Description

Technical Field

[0001] The utility model relates to the technical field of packaging bag production, in particular to a packaging bag tension control device. Background Technique

[0002] A packaging bag tension control device is an automated device used to ensure that the packaging bag remains properly tensioned during the packaging process. Through machinery and sensors, precise control is achieved to prevent the bag from being too loose or too tight, thereby improving packaging quality and production efficiency. This device is widely used in automated production lines in the food, pharmaceutical, and cosmetic industries, capable of increasing production efficiency, reducing human operation errors, and ensuring the consistency and stability of packaging quality.

[0003] After retrieval, the Chinese patent publication number is: CN216189794U, which discloses a tension control and adjustment device for packaging bag production, including a bottom plate and two fixed plates fixedly installed on the top of the bottom plate. On the opposite sides of the two fixed plates, an adjustment mechanism for tension control of the packaging bag is provided. For this tension control and adjustment device for packaging bag production, after the electric push rod extends and retracts, the movable shaft and the swing arm can rotate, thereby driving the connecting plate to move, and the connecting shaft and the tension roller move, so that the distance between the tension roller and the guide roller becomes larger or smaller, thereby adjusting the tension degree of the packaging bag passing through between the two tension rollers. Through the combined use of the lower anti-deviation block and the upper anti-deviation block, when the packaging bag passes through the front and rear inclined surfaces of the lower anti-deviation block and the upper anti-deviation block, the packaging bag can slide to the middle position between the lower anti-deviation block and the upper anti-deviation block, minimizing the deviation of the packaging bag during production and solving the problem of unobvious adjustment of the tension degree. However, in the actual use process, when adjusting the tension of packaging bags with too large an adjustment range, this device cannot complete it well and quickly, and the operation of the device needs to be paused first, and the device can only be run after the tension is adjusted, resulting in a reduction in production efficiency. Content of the Utility Model

[0004] In order to make up for the above deficiencies, the utility model provides a packaging bag tension control device, aiming to improve the problem in the prior art that it cannot be completed well and quickly, and the operation of the device needs to be paused first, and the device can only be run after the tension is adjusted, resulting in a reduction in production efficiency.

[0005] To achieve the above object, the utility model adopts the following technical solutions: A packaging bag tension control device includes a bottom plate. Fixed support plates are fixedly connected to the front and rear sides of the top of the bottom plate. A U-shaped plate is slidably connected to the bottom of the adjacent sides of the two fixed support plates.

Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0039] Refer to Figure 1 , Figure 3 and Figure 4 , an embodiment provided by the present invention: A packaging bag tension control device includes a bottom plate 1.

A fine adjustment mechanism 2 is arranged on the inner wall of the U-shaped plate 4. The fine adjustment mechanism 2 is used to finely adjust the position of the tensioning roller 1 12;

[0040] Specifically, when the tension needs to be adjusted, the electric telescopic rod 8 is activated, which can drive the moving bar 9 to move. At this time, the rotating support plates 10 on both sides thereof will move to the left side of the bottom plate 1, thereby driving the movement of the U-shaped plate 4 and the tensioning roller 12 above. As the U-shaped plate 4 moves towards the bottom of the bottom plate 1, the front rack 7 will be driven to move at this time, and through the meshing relationship, the gear 6 will rotate, and the rotating column 5 will drive the gear 6 on the other side to rotate.

[0045] Refer to Figure 1 、 Figure 2 and Figure 3 , at the top of the front end of the front fixed support plate 3, an alarm 20 is fixedly connected. Tension sensors 21 are arranged on both the front and rear sides of the first tension roller 12. A notch 26 is opened at the bottom of the front end of the front fixed support plate 3. At the top left of the adjacent ends of the two fixed support plates 3, a fixed block 22 is fixedly connected. A static brush 23 is fixedly connected to the bottom of the fixed block 22. At the right side of the front end of the front fixed support plate 3, a limiting block 24 is fixedly connected. A nameplate 25 is fixedly connected to the front side of the limiting block 24;

As the U-shaped plate 4 moves towards the bottom of the bottom plate 1, the front rack 7 will be driven to move at this time, and through the meshing relationship, the gear 6 will rotate, and the rotating column 5 will drive the gear 6 on the other side to rotate. Finally, the rear rack 7 will move towards the top of the bottom plate 1, so that the I-shaped plate 11 drives the second tension roller 13 to move towards the top of the bottom plate 1, so as to quickly complete the adjustment of the tension of the packaging bag. And through the fine adjustment mechanism 2, when the position of the first tension roller 12 needs to be finely adjusted, only need to rotate the regulating valve 206, which will drive the rotation of the threaded column 202. As the threaded column 202 rotates, the outer moving block 203 will move, and through the rotation of the sprocket 204, the outer chain 205 will be driven to rotate, so that the rear threaded column 202 will rotate together, realizing the simultaneous rotation of the two threaded columns 202, so that the position of the first tension roller 12 can be adjusted above the U-shaped plate 4, so as to ensure that it will not be loose or too tight.
