Description

Technical Field

[0001] The utility model relates to the technical field of bubble film production, in particular to a bubble film machine winding device. Background Art

[0002] Bubble wrap is a clean, lightweight packaging material consisting of a layer of small bubbles attached to a plastic film to provide cushioning protection for items. These bubbles are circular protrusions filled with enclosed air that help absorb shock and prevent damage to goods during handling, mailing, or transportation.

[0003] In the prior art, the comparative document publication number CN221543493U discloses a bubble film machine winding device, which can tension the bubble film and adjust the winding tightness of the bubble film. However, after the winding is completed, the bubble film needs to be cut. When cutting, the bubble film loses its tension, causing the bubble film to be scattered. In addition, during the winding process of the bubble film, the required number of meters is different, so the winding thickness of the bubble film is different. Therefore, the winding shaft needs to be set to a higher position, which makes it inconvenient for employees to remove the rolled bubble film. For this reason, we disclose a bubble film machine winding device. Utility Model Content

[0004] The utility model provides a rewinding device for a bubble film machine. After rewinding is completed, no matter how thick the rewound bubble film is, two driving components are started to make the bubble film roll close to the extrusion plate, so that the height of the bubble film roll is reduced and the limit on the rewinding shaft is released at the same time, which is convenient for taking out and will not make the bubble film roll scatter. This solves the problem that the traditional device needs to cut the bubble film after rewinding is completed. When cutting, the bubble film loses tension, thereby causing the bubble film to scatter. At the same time, since the rewinding shaft needs to be set to a higher position, it is inconvenient for employees to take off the rewound bubble film.

[0021] The present invention will be further described below in conjunction with specific embodiments. However, people familiar with the art should understand that the detailed description given here in conjunction with the drawings is for better explanation, and the structure of the present invention must go beyond these limited embodiments. For some equivalent replacement solutions or common means, they will not be described in detail herein, but they still fall within the scope of protection of this application.

[0022] Figures 1 to 4 This is the best embodiment of the present invention, Figures 1 to 5 The utility model is further described.

[0023] The utility model discloses a bubble film machine winding device, comprising a workbench 1, a fixed column 2 fixedly mounted on the top of the workbench 1, a movable column 3 slidably mounted on the top of the workbench 1 is provided on one side of the fixed column 2, a winding mechanism is mounted on the fixed column 2 and the movable column 3; a movable mechanism for moving the movable column 3 is mounted on the top of the workbench 1;

[0024] The moving mechanism is slidably mounted on the extrusion plate 13 on the top of the workbench 1. The bottom of the extrusion plate 13 is fixedly connected to the top of the workbench 1 through an extrusion spring 14. Two U-shaped fixing rods 17 are fixedly mounted on the top of the workbench 1. Sliders 18 are slidably sleeved on the two U-shaped fixing rods 17. The sides of the two slides 18 that are close to each other are fixedly connected to the two sides of the moving column 3. Four sliding rods 15 are fixedly mounted on the bottom of the extrusion plate 13. Four sliding grooves are provided on the top of the workbench 1. The four sliding rods 15 are respectively slidably mounted in the four sliding grooves. The sides of the two sliders 18 that are away from each other are rotatably mounted with rotating rods 16. The top ends of the two rotating rods 16 are respectively rotatably mounted on the sides of the two adjacent slide rods 15.

[0025] The winding mechanism includes two drive assemblies respectively mounted on the fixed column 2 and the movable column 3. Both drive assemblies are mounted with a movable block 7 connected through the drive assembly. A winding motor 8 is fixedly mounted on the side of the movable block 7 located on the fixed column 2. A rotating shaft 9 is fixedly mounted on the output end of the winding motor 8. A rectangular groove 25 is opened on the side of the rotating shaft 9 close to the movable column 3. A rectangular block 10 is movably mounted in the rectangular groove 25. The side of the rectangular block 10 extends to the outside of the rectangular groove 25 and is fixedly mounted with a winding shaft 11. A support sleeve 12 is fixedly mounted on the side of the other movable block 7. One end of the winding shaft 11 extends into the support sleeve 12.

[0026] By means of the above structure: when in use, the bubble film roll is connected to the winding shaft 11, and the winding motor 8 is started to drive the winding shaft 11 to rotate, thereby performing the winding operation. After the winding is completed, no matter how thick the rolled bubble film is, the two driving components are started to make the bubble film roll close to the extrusion plate 13, so that the height of the bubble film roll is reduced, and at the same time, the limit on the winding shaft 11 is released, which is convenient for taking and will not make the bubble film roll scattered.

[0027] The moving mechanism also includes two U-shaped blocks 21 fixedly mounted on the top of the fixed column 2, and a U-shaped plug rod 19 is slidably mounted in the two U-shaped blocks 21. The sides of the two slide bars 15 close to the U-shaped blocks 21 are provided with a card slot 22. The two ends of the U-shaped plug rod 19 are respectively in contact with the sides of the two adjacent slide bars 15, and the two card slots 22 correspond to the two ends of the U-shaped plug rod 19 respectively; two return springs 20 are fixedly mounted on the side of the U-shaped plug rod 19 close to the fixed column 2, and the ends of the two return springs 20 away from the U-shaped plug rod 19 are fixedly mounted on the side of the fixed column 2.

[0028] In this embodiment, the bubble film roll squeezes the extrusion plate 13, thereby causing the extrusion plate 13 to move downward, and the extrusion spring 14 is deformed. The movement of the extrusion plate 13 drives the two rotating rods 16 to rotate, and the rotation of the two rotating rods 16 drives the two sliders 18 to move, thereby causing the movable column 3 to move away from the fixed column 2. The movement of the movable column 3 drives the support sleeve 12 to move, and the movement of the support sleeve 12 causes the winding shaft 11 to separate from the support sleeve 12. When the slot 22 corresponds to the position of the U-shaped insertion rod 19, the distance between the support sleeve 12 and the winding shaft 11 is greater than the groove depth of the rectangular groove 25. Since the reset spring 20 is in a deformed state, under the action of the reset spring 20, the U-shaped insertion rod 19 is inserted into the slot 22 to complete the fixation of the extrusion plate 13, so that the extrusion plate 13 is tightly attached to the bubble film roll, and the bubble film roll will not be scattered, thereby realizing automatic disengagement and fixation of bubble film rolls of different thicknesses.

[0029] The height of the connection between the rotating rod 16 and the slide bar 15 is greater than the height of the connection between the rotating rod 16 and the slider 18. The advantage of this arrangement is that the extrusion plate 13 can drive the slider 18 away from the fixed column 2 through the rotating rod 16 when descending.

[0030] The driving assembly includes a moving groove 4 opened on the side of the fixed column 2 or the moving column 3, a servo motor 5 is fixedly installed on the top inner wall of the moving groove 4, a screw rod 6 is fixedly installed on the output end of the servo motor 5, and a moving block 7 is threadedly sleeved on the screw rod 6. The moving block 7 is slidably installed in the moving groove 4, and the side of the moving block 7 is fixedly connected to the side of the winding motor 8 or the support sleeve 12.

[0031] In this embodiment, the two servo motors 5 are started to make the two screw rods 6 rotate clockwise, thereby making the two moving blocks 7 move downward. The movement of the two moving blocks 7 drives the winding shaft 11 and the bubble film roll to move downward, so that the bubble film roll can be placed on the extrusion plate 13 for easy later removal.

[0032] Two groups of vertical plates 23 are fixedly installed on the top of the workbench 1. Two guide shafts 24 are rotatably installed on the sides of the two vertical plates 23 close to each other. When in use, the bubble film is passed through the four guide shafts 24 and then connected to the winding shaft 11. The bubble film can be aligned through the guide shafts 24.

[0033] The working principle and use process of the utility model are as follows: when in use, the bubble film is passed through the four guide shafts 24 and connected to the winding shaft 11, and then the rotating shaft 9 is rotated by starting the winding motor 8. The rotating shaft 9 drives the rectangular block 10 and the winding shaft 11 to rotate through the rectangular slot 25, thereby performing the winding operation;

[0034] After the rewinding is completed, the rewinding motor 8 is stopped. At this time, no matter how thick the rewound bubble film is, the two servo motors 5 are started to make the two screw rods 6 rotate clockwise, thereby making the two moving blocks 7 move downward, and the two moving blocks 7 move to drive the rewinding shaft 11 and the bubble film roll to move downward. When the bubble film rolls of different thicknesses come into contact with the extrusion plate 13, the bubble film roll squeezes the extrusion plate 13, thereby making the extrusion plate 13 move downward, and the extrusion spring 14 is deformed. The movement of the extrusion plate 13 drives the two rotating rods 16 to rotate, and the rotation of the two rotating rods 16 drives the two sliders 18 to move, thereby making the moving column 3 move away. The movable column 3 moves away from the fixed column 2, driving the support sleeve 12 to move. The movement of the support sleeve 12 causes the winding shaft 11 to separate from the support sleeve 12. When the slot 22 corresponds to the position of the U-shaped insertion rod 19, the distance between the support sleeve 12 and the winding shaft 11 is greater than the depth of the rectangular slot 25. Since the return spring 20 is in a deformed state, the U-shaped insertion rod 19 is inserted into the slot 22 under the action of the return spring 20 to complete the fixation of the extrusion plate 13, so that the extrusion plate 13 is tightly attached to the bubble film roll, and the bubble film roll will not be scattered, thereby realizing automatic detachment and fixation of bubble film rolls of different thicknesses;

[0035] At this time, the bubble film roll can be cut, and then the bubble film roll cut can be fixed with tape. After the fixation is completed, the bubble film roll is moved toward the moving column 3 to drive the reeling shaft 11 to move. The reeling shaft 11 moves so that the rectangular block 10 is out of the rectangular groove 25. At this time, the reeling shaft 11 can be taken out, and then the rectangular block 10 on the new reeling shaft 11 is aligned with the rectangular groove 25 and placed, and the reset spring 20 is pulled to move it out of the slot 22. Under the reaction force of the extrusion spring 14, the extrusion plate 13 and the moving column 3 are restored to their original state, thereby completing the fixation of the new reeling shaft 11, and then starting the two servo motors 5 to make the two screw rods 6 rotate counterclockwise to restore the device to its original state.

[0036] The above are merely preferred embodiments of the present invention and are not intended to limit the present invention in any other manner. Any person skilled in the art may utilize the above disclosed technical content to modify or remodel the present invention into equivalent embodiments. However, any simple modifications, equivalent variations, and modifications to the above embodiments that do not depart from the technical content of the present invention and are based on the technical essence of the present invention shall still fall within the scope of protection of the present invention.
