Description

Stretch film correction device

technical field

The utility model relates to stretch film packaging equipment, in particular to a stretch film deviation correcting device of the stretch film packaging equipment.

Background technique

Stretch film often deviates left and right during the conveying process before blister thermoforming, so it is necessary to set up a special deviation correcting component to correct the deviation, and the deviation correcting component in the prior art has a complex structure and high cost.

Contents of the invention

Aiming at the deficiencies of the prior art, the purpose of this utility model is to provide a stretch film deviation correcting device used in the stretch film conveying process, which has a simple structure and good deviation correction effect.

The utility model is implemented through the following technical solutions:

Stretch film deviation correction device is characterized in that it includes left and right deviation correction rollers. The left deviation correction roller is composed of left upper roller and left lower roller. The upper left and left lower rollers are relatively movable. The rolling film feeding direction of the left deviation correcting roller is inclined to the left to the traction and conveying direction of the stretch film; the right deviation correcting roller is composed of the upper right roller and the lower right roller, and the relative movement between the upper right and lower right rollers is set. When the right deviation correction works, the upper right and right The lower rollers are pressed against each other, and the rolling film feeding direction of the right deviation correcting roller is inclined to the right to the traction and conveying direction of the stretched film.

After adopting the above technical scheme, the working principle of the stretch film deviation correction device is: when the stretch film deviation occurs to the right, the right probe will detect the corresponding information, so the left deviation correction roller is put into the left deviation correction work, and the left upper and left lower rollers Press the left side of the stretch film tightly, since the rolling film feeding direction after the upper left and lower left rollers press the stretch film is inclined to the left to the traction and conveying direction of the stretch film, so the stretch film is being pulled and conveyed forward At the same time, it will also be rolled and pulled to the left, so that the stretch film will move to the left to achieve deviation correction; when the stretch film deviates to the left during the conveying process, the left probe will detect the corresponding information, so the right deviation correction roller will be put into operation. Right side correction work, the upper right and lower right rollers press the right side of the stretch film tightly, because the rolling film feeding direction after the upper right and lower right rollers press the stretch film is inclined to the right to the traction and conveying direction of the stretch film, so The stretched film is also rolled and drawn to the right while being pulled forward, so that the stretched film moves to the right to achieve deviation correction. The structure of the above-mentioned deviation correcting action is very simple, and the deviation correcting effect is very ideal. Compared with the prior art, it has outstanding substantive features and remarkable progress.

Preferably, the left tilt angle is controlled between 25-40 degrees, and the right tilt angle is controlled between 25-40 degrees.

Preferably, the lower left roller is fixedly set, the upper left roller is movable and pushed by the left cylinder, the lower right roller is fixed, and the upper right roller is movable and pushed by the right cylinder.

detailed description

As shown in Figure 1, the stretch film correction device of the present utility model includes left and right correction rollers, and the left correction roller is composed of a left upper roller 1 and a left lower roller 2, and the left lower roller 2 is fixedly arranged, and the roller seat 6 of the left lower roller 2 is on the lower fixed plate 14 is fixedly installed, and the left upper roller 1 is movable. The roller seat 5 of the left upper roller 1 is connected with the left cylinder 9 and is pushed by the left cylinder 9. The left cylinder 9 is fixedly installed on the upper fixed plate. When the left deviation is corrected, the left upper and left lower rollers They are pressed against each other, the rolling film feeding direction of the left deviation correcting roller is inclined to the left in the traction and conveying direction of the stretch film, and the left inclination angle is 25-40 degrees; the right deviation correcting roller is composed of the upper right roller 3 and the lower right roller 4, The lower right roller 4 is fixedly arranged, and the roller seat 8 of the lower right roller 4 is fixedly installed on the lower fixed plate 14, and the upper right roller 3 is movable, and the roller seat 7 of the upper right roller 3 is connected with the right cylinder 10 and is promoted by the right cylinder 10. The cylinder 10 is fixedly installed on the upper fixing plate. When the right deviation correction is working, the upper right and lower right rollers are pressed against each other. The rolling film feeding direction of the right deviation correcting roller is inclined to the right to the traction and conveying direction of the stretch film, and the right inclination angle is 25° -40 degree angle; the stretch film feeding end of the left correction roller is equipped with a left probe 11 that tracks and detects the position of the left side of the stretch film, and the left probe 11 controls the action of the right cylinder 10, and the stretch film of the right correction roller is fed into End is provided with the right probe 12 of tracking detection stretch film right side, and right probe 12 controls the action of left cylinder 9.

The working process of the present utility model is: as shown in Figure 2, the stretched film A passes between the left and right deviation correction rollers after being guided by the guide roller 13. When the stretched film A deviates to the right during the conveyance process, the right probe 12 will The corresponding information is detected, so the left cylinder 9 is controlled to move, the upper left roller 1 and the lower left roller 2 will press the left side of the stretch film A tightly, and the direction of rolling film feeding after the upper left and lower left rollers compress the stretch film is inclined to the left Depending on the traction and conveying direction of the stretched film, the stretched film will also be rolled and drawn to the left while being pulled forward, so that the stretched film A will move to the left to achieve deviation correction; when the stretched film A If deviation occurs to the left during the conveying process, the left probe 11 will detect the corresponding information, so the right cylinder 10 will be controlled to move, and the upper right roller 3 and the lower right roller 4 will press the right side of the stretch film A tightly. After the roller presses the stretch film, the direction of rolling film feeding is inclined to the right in the direction of traction and conveying of the stretch film, so the stretch film will also be rolled and drawn to the right while being pulled forward, so that the stretch film A produces a movement to the right for skew correction.
