Description

Paper feeding deviation correcting device for aseptic beverage filling machine

technical field

The invention relates to a device in the technical field of machinery, in particular to a paper-feeding deviation correcting device for an aseptic beverage filling machine.

Background technique

In liquid beverage packaging machinery, packaging paper materials with fresh-keeping functions are usually packaged into containers for liquid beverages, such as pillow-shaped packaging, brick-shaped packaging, and roof-top packaging. These packaging containers are all made of rolls of packaging paper through mechanical forming, disinfection, sealing and other processing links. In this process, the packaging paper has to go through a long paper path, including extrusion rollers, pressure control rollers, etc. During the movement of the packaging paper, the paper will inevitably deviate in its transverse direction. If this deviation is not corrected, then the centered vertical seal will not be guaranteed in the subsequent vertical sealing process. . Therefore, during the paper feeding process, there must be a link or device to adjust the paper to a stable centering state. This correcting device for controlling paper feeding is used to complete this function.

Through literature search and patent search, it is found that Chinese Patent Publication No. CN 1316368A, invention patent, invention name: device for adjusting the lateral position of the packaging material belt. The patent reads as: a device for adjusting the lateral position of a belt of packaging material on a packaging machine for producing packages filled with food products, the device has a slider that is movable laterally relative to the belt and carries a a clamping member that moves the belt laterally; and an assembly that detects the corresponding defined position of the belt and automatically adjusts the position of the slider based on the signal generated by the optical sensor. The complex structure of this technology leads to relatively high control costs, and there are problems in accuracy and stability, and the effect of control and correction is not ideal.

Contents of the invention

The purpose of the present invention is to overcome the deficiencies of the prior art, and provide a paper-feeding and deviation-correcting device for an aseptic beverage filling machine, which has a simple mechanism, low cost, and high reliability, and solves the problems of packaging materials in the aseptic beverage filling machine. Paper path correction problem.

The present invention is realized through the following technical solutions, the present invention includes: fixed roller, deviation correcting roller, frame, sliding platform, sliding block, movable end bearing bracket, fixed end bearing bracket, fixed roller fixed on the frame, one end of deviation correcting roller The fixed end bearing bracket is fixed on the frame, the other end is fixed on the sliding block, the sliding block is placed in the sliding platform, the sliding platform is fixed on the frame, and the movable end bearing bracket is connected with the sliding block.

The sliding platform is provided with a guide groove, and the sliding block is placed in the guide groove of the sliding platform.

One end of the deviation correcting roller adopts a self-aligning ball bearing and is placed in the fixed end bearing support; the other end of the deviation correcting roller adopts a radial ball bearing and is placed in the movable end bearing bracket.

The surface of the sliding block has a chute at an angle of 45 degrees to the axis of the deviation correction roller.

The movable end bearing bracket is connected in the slide groove of the sliding block.

Driven by the power device, the packaging paper material moves along the direction from the fixed roller to the guide roller. The fixed roller and the guide roller form a pair of rollers to realize the guide function. The fixed roller is fixed on the frame through a cylindrical bearing, and the self-aligning ball bearing at one end of the correction roller is fixed, so that the correction roller can rotate around this bearing at an appropriate angle on the paper path plane, and the radial ball bearing at the other end is placed in a On the movable bracket, the position of the rotation axis of the correction roller is forced to change through this movable bracket. During the rotation process, the movable bracket forms a relatively rotatable rotary pair on a cylindrical arc surface. In this way, the position of the paper path can be controlled very flexibly by adjusting the angle between the fixed roller and the correction roller. The deviation correction control signal can be given by the photoelectric switches on both sides of the paper path, or by the deviation correction control signal generating mechanism.

The sliding platform is fixed on the frame and can slide along the direction of the guide groove. The movable end bearing support can slide in this chute. When the sliding block slides along the axis of the correction roller, the 45-degree chute will drive the movable end bearing bracket to rotate at a certain angle with the fixed bearing bracket as the center, so that the rotation axis of the correction roller can rotate relative to the axis of the fixed roller to form a suitable clip. horn. In this way, a pair of rollers consisting of the fixed roller and the correction roller can form a certain angle offset in the plane of the paper path, and the angle of the offset can be changed by controlling the movement of the packaging paper to the left or right to achieve the purpose of deviation correction.

Compared with the prior art, the paper-feeding deviation correcting device for the aseptic beverage filling machine of the present invention has simple mechanism, low cost and high reliability. During the movement, the paper may slide along the direction of the axis of the cylinder, resulting in deviation. The invention adjusts the position of the axis of the correction cylinder according to the direction of deviation of the paper, so that it deviates from the axis of the fixed cylinder by an angle, thereby controlling Offset and centering of paper stock.
