Description

Slitting machine blade detection and grinding system

The present invention relates to the technical field of slitting machines, and in particular to a slitting machine blade detection and grinding system that can automatically perform slitting resistance detection and blade grinding operations on the annular belt-shaped blade of the slitting material sheet in the slitting machine.

The current slitting machine structure used to cut plastic, rubber and other material sheets into substrates of a predetermined thickness mainly has a cutting wheel on the left and right sides of the machine base, and an endless belt-shaped cutting knife is wound around the two cutting wheels. The cutting wheel is connected to a driving motor, so that when the slitting machine is started, the endless belt-shaped cutting knife can be driven by the two cutting wheels together. When the sheet of plastic, rubber and other materials is fed into the slitting area of the machine base of the slitting machine through the feeding mechanism, the sheet is cut by the cutting knife into a substrate of a predetermined thickness and output.

During the process of the slitting machine slitting the sheet into a substrate of a predetermined thickness, the cutter is often worn due to continuous slitting. The cutter becomes blunt due to wear, and the resistance of the cutter slitting the sheet increases, resulting in the cutter cutting the sheet not being smooth. Therefore, the existing slitting machine is equipped with two sets of sharpening mechanisms in the machine base. When the cutter is worn and blunt, the operator manually operates the sharpening mechanism to sharpen the blade of the cutter.

However, the knife sharpening mechanism of the above-mentioned slicing machine must be manually operated by the operator during use. The operator must judge the timing and state of sharpening based on experience, which is time-consuming and labor-intensive. In addition, during the sharpening process, the surface of the sharpening wheel is prone to retaining scraps after sharpening, which affects the sharpening performance, making it difficult to effectively perform the cutting operation.

The purpose of the present invention is to provide a slicing machine blade detection and grinding system to solve the inconvenience of the existing slicing machine's manual operation of the blade sharpening mechanism to grind the ring-shaped blade.

In order to achieve the above-mentioned purpose, the present invention provides a slicing machine cutter detection and grinding system, which can be installed in a machine base of a slicing machine, adjacent to the endless cutter driven by two cutter wheels in the slicing machine and the axle of the cutter wheels. The slicing machine cutter detection and grinding system is controlled by a computer of the slicing machine and includes: a slicing resistance detector, which can be connected to the axle of the cutter wheel, the slicing resistance detector is electrically connected to the computer, and can continuously or intermittently automatically detect the torque when the cutter wheel is driven, and transmitting the detected torque value to the computer, which determines whether the received torque value is greater than a preset value, and then decides whether to stop the sharpening mode or switch to the sharpening mode; and an electric sharpening device, which is arranged in the base of the slicing machine, and the electric sharpening device includes one or two electric sharpening modules controlled by the computer, each of which is controlled by the computer and can sharpen the blade of the cutter and withdraw the cutter and can automatically remove the debris generated by the cutter after grinding.

Through the overall creation of the above-mentioned slitting machine blade detection and grinding system, the slitting machine can continuously or intermittently detect whether the cutter is sharp during the process of cutting the plastic, rubber and other materials into substrates of predetermined thickness by combining the slitting resistance detector with the computer. When it is judged that the cutter has become blunt due to wear, resulting in the cutter cutting the sheet smoothly and the resistance increasing, the computer judges that the slitting resistance value detected by the slitting resistance detector is greater than the preset value, and the computer will automatically advance the electric knife sharpening device to perform the blade grinding of the cutter. The cutting machine can grind the blade and automatically remove the debris generated after the blade is ground. At the same time, the cutting resistance detector is combined with the computer to detect whether the blade is sharp. When the computer judges that the cutting resistance value detected by the cutting resistance detector is less than the preset value, the computer will make the electric sharpening device automatically stop the blade grinding of the blade and withdraw the blade. Therefore, the present invention provides a blade detection and grinding system for a cutting machine that can automatically perform blade detection and grinding operations, solving the inconvenience of the existing cutting machine using a manually operated sharpening mechanism to grind the ring-shaped blade.

As shown in FIG. 1 and FIG. 3, it discloses a partial schematic diagram of a slicing machine cutter detection and grinding system according to an embodiment of the present invention applied to a slicing machine. As can be seen from the figure, it can be installed in the machine base 1 of the slicing machine, adjacent to an endless cutter driven by two cutter wheels 10 in the slicing machine and an axle 101 of the cutter wheel 10. The slicing machine cutter detection and grinding system 2 is controlled by a computer of the slicing machine, and the slicing machine cutter detection and grinding system 2 includes a slicing resistance detector 20 and an electric sharpening device 30.

As shown in FIG1 , the cutting resistance detector 20 is installed in the cutting machine and connected to the axle 101 of the cutting wheel 10. The cutting resistance detector 20 is electrically connected to the computer and can continuously or intermittently detect the torque when the cutting wheel 10 is driven, and transmit the detected torque value to the computer. The computer determines whether the received torque value is greater than the preset value, and then decides to stop the sharpening mode or switch to the sharpening mode. The cutting resistance detector 20 can be a torque detector. The torque detector is a known product, and its specific structure and torque detection method are not described here.

As shown in Figures 1 to 4, the electric knife sharpening device 30 includes one or two sets of electric knife sharpening modules 30A, 30B controlled by a computer. Each of the electric knife sharpening modules 30A, 30B is controlled by a computer and can sharpen one side of the blade of the endless belt-shaped cutter and can automatically clean the debris generated after the cutter is sharpened. In this embodiment, the electric knife sharpening device 30 includes two sets of electric knife sharpening modules 30A, 30B, which are used to sharpen the two sides of the blade of the endless belt-shaped cutter respectively.

As shown in FIGS. 1 to 4 , the electric knife sharpening module 30A, 30B includes a knife holder 31 , a knife sharpening wheel 32 , a knife wheel motor 33 , a knife feed drive assembly 34 and a cleaning component 35 . The knife seat 31 has a pivot end 311, and the pivot end 311 is combined with the pivot 312 to pivot in the machine base 1. The grinding wheel 32 is pivoted in the knife seat 31. The knife wheel motor 33 is installed on the knife seat 31 and connected to the grinding wheel 32. The knife wheel motor 33 is controlled by a computer. The feed drive assembly 34 is arranged on the machine base 1 and connected to the knife seat 31. The feed drive assembly 34 can be controlled by a computer to drive the knife seat 31 to rotate with the pivot 312 as the rotation center until the grinding wheel 32 contacts the blade side of the cutter and retreats from the cutter. In this embodiment, the grinding wheels 32 of the two electric sharpening modules 30A and 30B are in a misaligned state.

As shown in FIGS. 1 to 4 , the feed drive assembly 34 includes a screw 341 and a servo motor 342. The screw 341 is threadedly connected to the tool holder 31. The servo motor 342 is installed on the machine base 1 and controlled by a computer. The spindle of the servo motor 342 is combined with a universal coupling 343 to connect the screw 341, so that the feed drive assembly 34 can be controlled by the computer to drive the grinding wheel 32 in the tool holder 31 to contact the blade of the cutter (i.e., feed) and retract the cutter (i.e., retract). The servo motor 342 of the controlled computer is combined with the screw 341 to be threadedly connected to the tool holder 31 that can rotate in the machine base 1, so that the state of the grinding wheel 32 in the tool holder 31 contacting the cutter can be fine-tuned to control the grinding amount of the cutter. The feed drive assembly 34 can also be replaced by other equivalent drive assembly components.

As shown in FIG. 4 , the cleaning component 35 is installed in the base 1 and can be connected to an external working fluid supply source. The working fluid can be a gas such as air or a liquid such as water. The cleaning component 35 can be controlled by a computer to spray pressurized working fluid toward the grinding wheel 32 to remove the debris left on the surface of the grinding wheel 32 during grinding, so that the grinding wheel 32 can maintain its grinding performance.

Regarding the use of the slitting machine cutter detection grinding system 2 of the present invention in the slitting machine, please refer to Figures 1 to 2 and Figures 5 to 6. When the slitting machine is started, the ring-shaped cutter 11 is driven by the two cutter wheels 10. When the sheet 40 of plastic, rubber or other materials is fed into the slitting area of the slitting machine through the feeding mechanism, the cutter 11 cuts the sheet 40 into a substrate of a predetermined thickness and outputs it.

When the slitting machine is slitting the sheet 40 into a substrate of a predetermined thickness, the cutter will be worn due to continuous slitting of the sheet 40. The slitting machine cutter detection and grinding system 2 of the present invention uses a slitting resistance detector 20 in combination with a computer to continuously or intermittently detect whether the cutter 11 is sharp. The cutter 11 will become blunt due to wear, resulting in uneven cutting and increased slitting resistance when the cutter 11 slitting the sheet 40. The slitting resistance detector 20 can detect whether the cutter 11 is slitting the sheet 40. The cutting resistance value at that time is transmitted to the computer. When the computer judges that the cutting resistance value detected by the cutting resistance detector 20 is greater than the preset value, it switches to the sharpening mode. The computer controls the electric sharpening device 30 to automatically advance the knife to perform the blade sharpening of the cutter 11. At the same time, the computer controls the cleaning component 35 to spray the pressurized working fluid toward the sharpening wheel 32 to remove the debris left on the surface of the sharpening wheel 32 during sharpening, so that the sharpening wheel 32 can maintain its sharpening performance.

Among them, the two electric knife sharpening modules 30A and 30B of the electric knife sharpening device 30 are respectively controlled by a computer, so that the servo motor 342 drives the screw 341 to rotate and drives the knife sharpening wheel 32 of the knife seat 31 to contact the blade of the cutter 11. At the same time, the knife sharpening wheel 32 is driven by the knife wheel motor 33 controlled by the computer to perform the grinding operation on the cutter 11, and at the same time, the cleaning component 35 is used to remove the debris remaining on the surface of the knife sharpening wheel 32. During the process of the electric knife sharpening device 30 sharpening the blade of the cutter 11, the cutting resistance detector 20 is combined with the computer to detect whether the cutter 11 is sharp. When the computer judges that the cutting resistance value detected by the cutting resistance detector 20 is less than the preset value, it switches to the stop sharpening mode, and the computer makes the electric knife sharpening device 30 automatically stop sharpening the blade of the cutter 11 and withdraw the cutter, and stops the cleaning component 35 from spraying the pressurized working fluid. Therefore, the present invention provides a cutter detection and grinding system 2 for a cutter that can automatically perform cutter detection and grinding operations, solving the inconvenience problem of the existing cutter machine using a manually operated sharpening mechanism to grind the ring-shaped cutter.
