Description

A garbage bag breaking device

technical field

The invention belongs to the field of mechanical equipment, in particular to a bag breaking device.

technical background

The bag breaker is an automatic cutting device widely used in chemical industry, garbage disposal, building materials, metallurgy, environmental protection and other fields. It mainly includes components such as motors, belts, and cutters. In recent years, when dealing with materials that endanger human health or have strong odor, toxic, flammable, and high dust, bag breaking devices are often used to separate bag materials. The general processing steps are: belt conveyor automatically feeding bags, cutting and breaking bags, bag material separation and unloading.

With the further improvement of environmental protection requirements, the standard of garbage classification is also improved accordingly. The preferred process is increased to first break the bag, separate the bag material, and then classify the garbage. Therefore, the use of bag breaking devices in the field of garbage disposal is becoming more and more common. At present, most domestic waste treatment plants use dual-shaft shredders to shred the original waste and then classify it. This method of processing will shatter plastic packaging bags, glass bottles, and a small amount of construction waste without sorting, making it difficult to sort the debris later. On the one hand, the difficulty of sorting and the risk factor of sorting personnel have been greatly improved. On the other hand, broken glass and construction waste enter the composting workshop with other garbage, and enter the farmland with the organic fertilizer, which is difficult to decompose naturally and will cause irreversible harm to the cultivated land and crops.

SUMMARY OF THE INVENTION

The purpose of the present invention is to provide a bag breaking device, which avoids cutting sharp objects such as glass products and construction waste, and prevents the sorting difficulties caused by mixing large wastes after being broken.

For achieving the above object, the technical scheme of the present invention is:

The garbage bag breaking device of the present invention includes a tool holder main body (901), a blade (902), a movable shaft (909), a compression spring (907) and a pressing plate (908).

The movable shaft (909) is fixedly connected to the main body of the tool holder (901), the pressing plate (908) is movably connected to the lower part of the main body of the tool holder (901) through the movable shaft (909), and the compression spring (907) is connected to the movable shaft ( 909) is set as the center, and is fixed on the main body of the tool holder (901).

The tool holder main body (901) is provided with several beams perpendicular to the axial direction to fix several sets of blades (902), and the press plate (908) is provided with slits (910) into which the blades (902) can be inserted.

When the pressing plate (908) is pressed down to the bottom, the knife holder main body (901) moves at a lower speed under the action of the compression spring (907), and is inserted into the knife slit (910). When the tool holder body (901) moves upward, the pressing plate (908) rebounds under the action of the compression spring (907).

The garbage bag breaking device further comprises a motor (1), a driving pulley (2) and a cam (8). Fixed connection.

Further, the compression spring (907) is fixed on the tool holder main body (901), and is arranged in parallel with the blade (902).

Preferably, the axial edge of the blanking plate (908) is bent obliquely upward, and the blanking plate (908) is bent upwards by 90° with the side perpendicular to the axial direction, and is placed in the frame of the tool holder body (901).

Preferably, no less than 4 blades (902) are provided in each group.

The beneficial effects of the present invention are:

The bag breaking device of the present invention can be vertically arranged above the belt conveyor to cut the bagged garbage on the conveyor belt. The compression spring slows down the pressing speed of the blade, avoids shredding glass or building materials and other fragile waste, ensures the rapid progress of the sorting task, and ensures the safety of the sorting personnel.

Detailed ways

The garbage bag breaking device shown in FIG. 1 includes a tool holder body 901 , a blade 902 , a compression spring 907 , a pressing plate 908 and a movable shaft 909 .

The movable shaft 909 is fixedly connected to the tool holder main body 901 , the pressing plate 908 is movably connected to the lower part of the tool holder main body 901 through the movable shaft 909 , and the compression spring 907 is arranged around the movable shaft 909 and fixed on the tool holder main body 901 .

The tool holder main body 901 is provided with several beams perpendicular to the axial direction to fix several sets of blades 902 , and the pressing plate 908 has a slit 910 into which the blades 902 can be inserted.

When the pressing plate 908 is pressed down to the bottom, the main body 901 of the knife holder moves down at a lower speed under the action of the compression spring 907 and is inserted into the knife slit 910 . When the tool holder body 901 moves upward, the pressing plate 908 rebounds under the action of the compression spring 907 .

The compression spring 907 is fixed on the main body 901 of the tool holder through a fixing nut 906 and is arranged in parallel with the blade 902 .

Preferably, the axial edge of the pressing plate 908 is bent obliquely upward, and its width is larger than the width of the tool holder main body 901 , so that the rubbish that is broken after being pressed will not enter above the pressing plate 908 by mistake. The pressing plate 908 is bent upwards by 90° with the side perpendicular to the axial direction, and is placed in the frame of the main body 901 of the tool holder to ensure the stability of the position of the pressing plate.

Preferably, no less than 4 blades 902 are provided in each group.

Further, as shown in FIG. 2 , the garbage bag breaking device also includes a motor 1, a driving pulley 2, a transmission belt 3, a driven pulley 4, a sprocket 5, a chain 6, a cam mounting seat 7, a cam 8, and a knife rest. 9.

The tool holder 9 includes a tool holder body 901 , a blade 902 , a blade pressing plate 903 , a rubber pad 904 , a bolt 905 , a fixing nut 906 , a compression spring 907 and a pressing plate 908 .

The motor 1 is directly connected to the drive pulley 2 , the drive pulley 2 is connected to the driven pulley 4 through the transmission belt 3 to rotate, and the driven pulley 4 transmits power to the cam 8 through the sprocket 5 . The tool holder main body 901 is fixedly connected with the cam 8, and after the machine is turned on, the cam 8 drives the tool holder 901 to rotate.

The pressing plate 908 is movably connected with the main body 901 of the tool holder by the movable shaft 909 , the pressing spring 907 is centered on the moving shaft 909 and is fixed under the main body 901 of the tool holder, and the blade 902 is arranged between the pressing plate 903 of the blade and the rubber pad 904 . During this time, bolts 905 fix the blade pressing plate 903 , the blade 902 and the rubber pad 904 on the beam of the main body of the blade holder 901 to ensure the stability of the blade 902 .

During operation, the bag breaking device of the present invention is vertically arranged on the belt conveyor for transporting garbage bags. With the rotation of the cam 8, the pressing plate 908 contacts and compresses the bagged garbage, the compression spring 907 compresses, and the blade 902 is removed from the knife seam. Insert and swipe in 910, after the garbage bag is punctured, the blade 902 is lifted up with the knife holder body 901, and the pressing plate 908 quickly rebounds with the compression spring 907, reducing the obstruction to the conveying of the garbage bag.

The above-mentioned garbage bag breaking device can be applied to the preliminary garbage classification of the garbage yard, breaking the bag quickly and conveniently without breaking other fragile garbage such as glass products and construction waste.
