Abstract
Description
Technical Field
[0001] This utility model relates to an improved invention of packaging bag processing equipment, and in particular to a winding mechanism of packaging bag processing equipment. Background Technology
[0002] The sides of the roll are coated with adhesive longitudinally and sealed longitudinally to form a continuous bag blank. If there are no inserts on both sides of the bag blank, the middle part of the bag blank has three layers and the two sides have two layers. If there are inserts on both sides of the bag blank, the middle part of the bag blank has three layers and the two sides have four layers. During the winding process, the thickness difference between the parts with more layers and the parts with fewer layers accumulates. The thicker the roll, the greater the difference. It is easy for the roll to collapse during the winding process, and the amount of bag blank wound in one winding is small. Summary of the Invention
[0003] In view of the technical problems existing in the background art, the technical problem solved by this utility model is to provide a winding mechanism for packaging bag processing equipment that can wind up a large quantity at one time and is not easy to collapse.
[0004] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: the winding mechanism of the packaging bag processing equipment is characterized by including a winding power roller, a moving component that causes the substrate to reciprocate laterally and achieves lateral misalignment of the substrate during winding, and a detector for collecting substrate edge information. The winding power roller is connected to a motor, the substrate conveying direction is forward, and the winding power roller is in front of the moving component. The detector and the moving component are both connected to a controller. The detector sends the collected substrate edge information to the controller, and the controller sends instructions to the moving component based on the received substrate edge information.
[0005] This invention uses a moving component to make the forward-feeding substrate move laterally back and forth. The range of the lateral back and forth movement is controlled by a controller. In this way, the winding substrate is laterally misaligned, so that the part with more layers is evenly distributed laterally and will not be concentrated in one position. This makes the thickness distribution of the wound roll even in the lateral direction, less prone to collapse, and allows for the winding of more material at one time.
[0006] Preferably, the moving component includes a moving base and a driving member for driving the moving base to move left and right or swing back and forth. A first guide roller and a second guide roller are rotatably disposed on the moving base. The second guide roller is disposed in front of the first guide roller, and the substrate passes around the first guide roller and the second guide roller in sequence.
[0007] Preferably, the movable seat is slidably mounted on the first guide rail and the second guide rail, which are inclinedly mounted on the machine base and longitudinally symmetrical. When one end of the movable seat moves upward along the first guide rail, the other end moves downward along the second guide rail. The first and second guide rollers tilt, causing the forward-pulled substrate to shift accordingly. When the movable seat swings in opposite directions along the first and second guide rails, the first and second guide rollers tilt in opposite directions, causing the forward-pulled substrate to shift accordingly, thus causing the wound substrate to be laterally misaligned.
[0008] Preferably, the driving component includes a motor, a telescopic rod, and a connecting rod. One end of the connecting rod is rotatably connected to the telescopic rod, and the other end of the connecting rod is connected to the movable seat. The motor is connected to the telescopic rod and drives the telescopic rod to extend and retract laterally. The motor drives the telescopic rod to extend and retract, which in turn causes the movable seat to swing back and forth along the first and second guide rails, resulting in more stable mechanical transmission.
[0009] Preferably, the detector is a slotted photoelectric sensor and is positioned in front of the moving part. The slotted photoelectric sensor has a groove for the edge of the substrate to enter. Continuously collecting edge information of the substrate allows for precise control of the substrate's lateral movement range, improving the winding effect. Attached Figure Description

[0016] The following describes the embodiments and related details and working principles of this utility model with reference to the accompanying drawings. The winding mechanism of this packaging bag processing equipment includes a winding power roller 5, a moving component that causes the substrate 1 to reciprocate laterally and achieves lateral misalignment of the wound substrate, and a detector 4 that collects edge information of the substrate 1. The wound substrate can also be referred to as a material roll 7. The winding power roller 5 is connected to a motor. The substrate 1 is conveyed forward, and the winding power roller 5 is in front of the moving component. The substrate 1 is wound around the winding power roller 5 onto a winding shaft 6. The winding shaft 6 is close to the winding power roller 5, and its surface is always in contact with the winding power roller 5. When the winding power roller 5 rotates, it drives the winding shaft 6 to rotate through friction. The two rotate in opposite directions, and the substrate 1 is wound onto the winding shaft 6. The detector 4 and the moving component are both connected to a controller. The detector 4 sends the collected edge information of the substrate 1 to the controller, and the controller sends instructions to the moving component based on the received edge information of the substrate 1. The detector 4 is a groove-shaped photoelectric eye and is located in front of the moving part. That is, the substrate being pulled forward passes through the detector first. The groove-shaped photoelectric eye has a groove for the edge of the substrate 1 to enter. The substrate 1 passes through the groove-shaped photoelectric eye, and the groove-shaped photoelectric eye continuously collects the edge information of the substrate 1.
[0017] The moving component causes the substrate 1 to move laterally back and forth. The range of this lateral movement is controlled by a controller. For example, if the substrate 1 moves laterally by 6 centimeters, and the detector 4 detects a 3-centimeter shift to the left at the edge of the substrate 1, the controller sends a command to the moving component to shift the substrate 1 to the right. Similarly, if the detector 4 detects a 3-centimeter shift to the right at the edge of the substrate 1, the controller sends a command to the moving component to shift the substrate 1 to the left. This process is repeated to precisely control the range of lateral movement of the substrate 1. Simultaneously, the left and right shifts of the substrate 1 cause lateral misalignment of the substrate 1 on the take-up shaft 6. Figure 5 In the middle, the substrate 1 of the adjacent inner and outer layers is staggered laterally. The part with more layers is evenly distributed laterally and will not be concentrated in one position. For example, the longitudinal seal in the middle is thicker and 5 cm wide, while other parts are thinner. After the lateral staggered winding, assuming the offset range is 6 cm, the longitudinal seal in the middle of the wound roll 7 is laterally expanded to 11 cm. The lateral thickness distribution is even, so it is not easy to collapse and more can be wound at once. Moreover, one side edge of the inner layer is covered by the outer layer. As the layers are wound one by one, the edge of the inner layer is compacted, the side crease is more stable, and the formed bag is straighter.
[0018] The moving component includes a movable seat 8 and a driving component that drives the movable seat to move left and right or swing back and forth. A first guide roller 2 and a second guide roller 3 are rotatably mounted on the movable seat 8. The second guide roller 3 is positioned in front of the first guide roller 2, and the substrate 1 passes around the first guide roller 2 and the second guide roller 3 in sequence. When the movable seat 8 moves to the right or swings clockwise, the substrate 1 shifts to the right; conversely, the substrate 1 shifts to the left. Swinging the movable seat 8 is preferred to reduce the impact on the substrate 1 in the input direction. The movable seat 8 is slidably mounted on a first guide rail 11 and a second guide rail 12. The first guide rail 11 and the second guide rail 12 are inclined on the machine base and are longitudinally symmetrical. The driving component includes a motor 13, a telescopic rod 10, and a connecting rod 9. One end of the connecting rod 9 is rotatably connected to the telescopic rod 10, and the other end of the connecting rod 9 is connected to the movable seat 8. The motor 13 is connected to the telescopic rod 10 and drives the telescopic rod 10 to extend and retract laterally. Motor 13 drives telescopic rod 10 to extend and retract, while telescopic rod 10 drives movable seat 8 to swing back and forth along first guide rail 11 and second guide rail 12, making the mechanical transmission more stable. (See attached image) Figure 2-4 When the telescopic rod 10 retracts, the left end of the movable seat 8 moves upward along the first guide rail 11, and the right end moves downward along the second guide rail 12. The first guide roller 2 and the second guide roller 3 swing clockwise, and the substrate 1 that is being pulled forward shifts to the right. When the telescopic rod 10 extends, the movable seat 8 swings in opposite directions along the first guide rail 11 and the second guide rail 12. That is, the left end of the movable seat 8 moves downward along the first guide rail 11, and the right end moves upward along the second guide rail 12. The first guide roller 2 and the second guide roller 3 tilt in opposite directions, and the substrate 1 that is being pulled forward shifts to the left. This causes the wound roll to be laterally misaligned.
