Description

Technical Field

[0001] This utility model relates to the field of membrane processing equipment technology, and in particular to an edge-gathering mechanism. Background Technology

[0002] Currently, in the production process of films, such as BOPP film and stretch film, it is necessary to trim the film edges to determine the width and remove excess material. The edge-collecting mechanism is used to collect and roll up these trimmed edges. Traditionally, during operation, the waste material is collected by the left-right movement of the winding device and the winding reel. This can lead to unstable tension, uneven winding, and inconvenient operation. In addition, during the winding process, the winding reel rotates continuously at high speed. If the operator mishandles the process and clothing comes into contact with the edge material, the friction generated by the rotation can instantly pull the contacting object into the winding reel. This can also cause the worker to rotate with the winding reel, and during the rotation, the worker's body may be thrown against the equipment, causing injury or death. Utility Model Content

The support plate is also provided with a rocker arm that drives the receiving tray to rotate. A cylinder is fixedly connected to the support plate. The piston rod of the cylinder is rotatably connected to one end of the floating roller arm. A resistance ruler is also provided on one end of the cylinder and the floating roller arm.

[0025] Example

[0026] like Figures 1 to 5 As shown, this utility model proposes an edge-gathering mechanism, including a support plate 1 and a film 3. An adjustment mechanism is used to adjust the tension of the film 3. A bracket 9 is fixedly connected to the support plate 1, and a take-up tray 10 for winding the film 3 is rotatably connected to the bracket 9. The take-up tray 10 is rotatably connected to the bracket 9 and is used to wind the edge material generated by cutting the film 3. A winding slot 101 is provided on the take-up tray 10 to facilitate the insertion and winding of the edge material. The take-up tray 10 has a winding slot 101 for inserting the film. The winding slot 101 is used to insert the edge material of the film 3, so that the edge material can be neatly wound on the take-up tray 10, ensuring the winding effect. The clamping plate of the take-up tray 10 away from the bracket 9 is detachable. The two clamping plates form the winding slot 101, which ensures that the wound edge material can be taken out after the movable clamping plate is removed.

[0027] Among them, such as Figure 1 As shown, the support plate 1 is equipped with an adjustment mechanism, which includes a transition wheel 2, a floating roller arm 4, a wire guide 5, and a rubber pressure roller 8, all sequentially arranged on the support plate 1 to support the film 3. The rubber pressure roller 8 is pressed down by the cylinder 6, working in conjunction with the floating roller arm 4 to press the edge material into the winding slot 101. Through elastic contact, the edge material is subjected to uniform force, ensuring tight winding without loosening. The transition wheel 2 guides the trimmed film 3, allowing it to move along a predetermined path and ensuring smooth film transport. The floating roller arm 4 is rotatably connected to the piston rod of the cylinder 6, adjusting the tension of the film 3 by swinging. Changes in tension are monitored by a resistance ruler 7. The support plate 1 also includes a rocker arm 11 that drives the take-up tray 10 to rotate. The rocker arm 11 drives the take-up tray 10 to rotate and facilitates manual adjustment of the angle of the take-up tray 10, improving operational convenience. A cylinder 6 is fixedly connected to the support plate 1. The cylinder 6 drives the floating roller arm 4 to swing by extending and retracting its piston rod, thereby adjusting the tension of the film 3. The amount of extension and retraction is controlled by the control system based on the signal fed back by the resistance ruler 7. The piston rod of the cylinder 6 is rotatably connected to one end of the floating roller arm 4. A resistance ruler 7 is also provided on one end of the cylinder 6 and the floating roller arm 4. The resistance ruler 7 monitors the position change of the floating roller arm in real time, converts it into an electrical signal, and feeds it back to the control system to adjust the action of the cylinder 6.

[0028] In addition, such as Figure 4 , Figure 5As shown, a brake mechanism is installed on the bracket 9, which is opened by abutment. The brake mechanism includes a rotating seat 95 fixedly connected to the bracket 9. A stop rod 96 is rotatably connected inside the rotating seat 95. One end of the stop rod 96 is connected to a stop head, and the other end is connected to a brake pad 97. Under the abutment of the trigger lever 94, the stop rod 96 rotates, causing the brake pad 97 to press against the take-up tray 10, thereby braking the take-up tray 10. A stop head 98 is fixedly connected to one end of the stop rod 96. When the stop head 98 is abutted by the trigger lever 94, it causes the stop rod 96 to rotate, which is the key component for triggering the brake mechanism. A first spring 99 is fixedly connected inside the rotating seat 95. One end of the first spring 99 is fixed to the inner wall of the rotating seat 95, and the other end is fixed to the stop rod 96. It plays a buffering role when the brake mechanism is activated, and at the same time helps the stop rod 96 to return to its original position. The end of the first spring 99 away from the inner wall of the rotating seat 95 is fixedly connected to the stop rod 96. The braking mechanism linkage process is as follows: personnel are drawn in, trigger lever 94 is blocked, connecting rod 93 pushes the abutment 98, abutment 96 rotates and causes brake pad 97 to stick to the receiving tray 10, first spring 99 buffers the braking impact force, and second spring 901 resets trigger lever 94.

[0029] It is worth noting that, such as Figures 2 to 4 As shown, the support 9 is also equipped with a stop mechanism to drive the brake mechanism. The stop mechanism includes a rotating shaft block 102 fixedly connected to the take-up tray 10. The rotating shaft block 102 is rotatably connected to the support 9. A retaining sleeve 92 is movably fitted on the rotating shaft block 102. A connecting rod 93 is fixedly connected to the outer wall of the retaining sleeve 92. A trigger rod 94 that abuts against the abutment head 98 is fixedly connected to the end of the connecting rod 93 away from the retaining sleeve 92. When a worker is accidentally caught in the take-up tray 10, the trigger rod 94 will abut against the trigger rod 94. The trigger rod 94 will drive the abutment head 98 to move through the connecting rod 93, thereby activating the brake mechanism. A protective baffle 91 is also fixedly connected to the support 9. The protective baffle 91 is fixed to the support 9 to prevent edge material from splashing during the winding process, thus playing a safety protection role.

[0030] Furthermore, such as Figures 4 to 5 As shown, a brake pad 97 is fixedly connected to the end of the stop rod 96 away from the stop head 98. The brake pad 97 is made of high-friction rubber. When it contacts the raised surface of the take-up tray 10, it increases the friction force to quickly stop the take-up tray 10. The raised design further enhances the braking effect. The side of the take-up tray 10 near the ferrule 92 has multiple raised protrusions, which increase the friction force of the contact.

[0031] Furthermore, such as Figure 4As shown, a second spring 901 is fixedly connected to the rotating seat 95. One end of the second spring 901 is fixed to the rotating seat 95, and the other end is fixed to the connecting rod 93. After the braking mechanism is activated, it helps the connecting rod 93 and the trigger lever 94 to reset, ensuring the normal operation of the mechanism. The end of the second spring 901 away from the rotating seat 95 is fixedly connected to the connecting rod 93.

[0032] In this embodiment, when using the edge-gathering mechanism, the trimmed film 3 is guided by the transition wheel 2 and tension controlled by the floating roller swing arm 4. When the tension is low, the resistance gauge 7 installed at the connection between the cylinder 6 and the floating roller swing arm 4 monitors its position change in real time to reflect the film tension and feeds the signal back to the control system. Based on this, the extension and retraction of the cylinder 6 are adjusted, and the floating roller swing arm 4 is driven to swing upward through the retraction of the fisheye joint to tighten the film 3, thereby achieving dynamic tension balance and ensuring stable tension during the edge-gathering process. At the same time, when the film 3 is bonded to the rubber pressure roller 8, the retraction of the cylinder 6 causes the end of the floating roller swing arm 4 to press tightly against the rubber pressure roller 8, so that the film 3 is subjected to uniform force in real time and maintains a neat and compact winding state.

[0033] When the film 3 is wrapped around the receiving tray 10, due to operator error, it gets caught in the receiving tray 10 and begins to rotate. Simultaneously, the operator caught in the receiving tray 10 will rotate along its trajectory. This causes the operator to press against the trigger lever 94, which then drives the connecting rod 93 to press against the abutment 98. This causes the abutment 98 to rotate the abutment rod 96 towards the receiving tray 10. The abutment rod 96 then causes the brake pad 97 to press tightly against the protruding side of the receiving tray 10, thus stopping the receiving tray 10 and preventing further injury to the operator caught in the rotating film.

[0034] The preferred embodiments of this utility model described above are merely illustrative of the present utility model. These preferred embodiments do not exhaustively describe all details, nor do they limit the utility model to any specific implementation. Clearly, many modifications and variations can be made based on the content of this specification. This specification selects and specifically describes these embodiments to better explain the principles and practical applications of this utility model, thereby enabling those skilled in the art to better understand and utilize it. This utility model is limited only by the claims and their full scope and equivalents.
