[0002] Cling film is a plastic packaging product, usually made through polymerization reaction with ethylene as the masterbatch. Cling film can be divided into three categories: the first is polyethylene, referred to as PE, which is mainly used for food packaging and is harmless to the human body. It is also used to preserve fruits and vegetables; the second is polyvinyl chloride, referred to as PVC, which can also be used for food packaging, but it is harmful to the human body; the third is polyvinylidene chloride, referred to as PVDC, which is mainly used for packaging of cooked food, ham and other products. Cling film has moderate oxygen permeability and moisture permeability, which regulates the oxygen and water content around the preserved food, blocks dust, and thus prolongs the shelf life of food.

[0045] When the present invention is in use, firstly, the two reciprocating cylinders 703 corresponding to the first combining hole 305 and the second combining hole 307 on the separation mechanism 7 are controlled by the controller to work, and the sliding rod 705 in the sliding rod connecting hole 702 on the cylinder body 701 and the sleeve 706 on the sliding rod 705 are moved toward the direction of the down-feeding mechanism 3 by the reciprocating cylinder 703, and the sleeve 706 is driven to move away from the limited installation roller assembly 604 coupled thereto by the movement of the sliding rod 705, and at the same time, the end of the sliding rod 705 away from the sleeve 706 moves to the inside of the first combining hole 305 and the second combining hole 307 on the rotating arm 306, and then the first electro-hydraulic push rod 302 on the down-feeding mechanism 3 is controlled by the controller to work, and the top is telescoped by the first electro-hydraulic push rod 302 The fixing plate 303 on the end and the connecting piece 304 installed on the fixing plate 303 move downward, and the first connecting hole 305 moves downward to drive the rotating arm 306 to move downward, thereby driving the sliding rod 705 coupled in the first connecting hole 305 and the second connecting hole 307 to rotate around the connecting shaft 5 in a circle, and the cylinder body 701, the sliding rod 705 and the sleeve 706 are staggered with the limit installation roller assembly 604, so as to install the cling film reel 12. After the installation is completed, the rotating arm 306 is pushed to the original position by the first electro-hydraulic push rod 302, and then the cylinder body 701 on the separation mechanism 7 is controlled by the controller to push the sliding rod 705 and the sleeve 706 back, thereby re-coupling the sleeve 706 and the limit installation roller assembly 604, and then the second servo is used to control the cylinder body 701 on the separation mechanism 7 to push the sliding rod 705 and the sleeve 706 back. The servo motor 603 works to drive the limit installation roller assembly 604 on the same plane as the guide roller 11 to rotate for winding. After the cling film roll tube 12 is wound, the controller controls the first servo motor 501 to rotate and drive the connecting shaft 5 to rotate 90°. The connecting shaft 5 rotates 90° to drive the limit installation roller assembly 604 on the winding mechanism 6 to rotate 90°, thereby rotating the limit installation roller assembly 604 for winding to the top. At the same time, the limit installation roller assembly 604 at the bottom rotates to the position where the original limit installation roller assembly 604 is in the same plane as the guide roller 11. Then, the controller controls the third servo motor 802 to work, and the third servo motor 802 drives the first rotating shaft 801 to rotate. The first rotating shaft 801 rotates to drive the connecting arm 803.

In the process of winding, the lower pressing mechanism 10 can also make the cling film wind smoothly. At the same time, through the setting of the limit column 401 of the limit rod 1002,The second pressing roller 1007 is always kept in contact with the position-limiting installation roller assembly 604, and the cut cling film falls and hangs on the position-limiting installation roller assembly 604 to be rolled up by gravity. The second pressing roller 1007 is pressed, and the second servo motor 603 on the position-limiting installation roller assembly 604 to be rolled up works to roll up the next cling film roll tube 12, so that the cling film roll tube 12 can be replaced without stopping the device, and the rolling efficiency is improved.

[0047] See also Figure 1-9 , which is different from Example 1 in that:

[0049] Two sliding grooves 60411 are provided on both ends of the inner wall of the first inner cavity 60417, and sliders 60413 are slidably installed inside the sliding grooves 60411. A spring 60412 is fixedly connected to one end of the slider 60413 close to the connecting block 6043, and one end of the spring 60412 away from the slider 60413 is fixedly connected to the inner wall of the sliding groove 60411. A third rotating member 60414 is fixedly installed on the top of the slider 60413, and a second connecting rod 60415 is rotatably installed on the third rotating member 60414. A fourth rotating member 60416 is rotatably installed on one end of the second connecting rod 60415 away from the third rotating member 60414, and the fourth rotating member 60416 is fixedly installed on the bottom surface of the arc-shaped top block 60410.

[0050] When the cling film roll 12 is installed, the sleeve 706 is recoupled with the limit installation roller assembly 604, and the protrusion 7061 in the sleeve 706 passes through the matching connecting block 6043 and the connecting column 6044 to abut against the top plate 6046 on the sleeve 6045, and the top plate 6046 is pushed inward, and the top plate 6046 moves inward to drive the sleeve 6045 to move, and the movement of the sleeve 6045 drives the first rotating member 6047 on the sleeve 6045 to move, and the movement of the first rotating member 6047 drives the first rotating member 6047 to drive ... The first connecting rod 6048 rotatably mounted on the moving member 6047 moves upward, thereby moving the second rotating member 6049 on the first connecting rod 6048 and the arc-shaped top block 60410 on the second rotating member 6049 upward, and the arc-shaped top block 60410 moves upward to drive the second connecting rod 60415 to move, and the second connecting rod 60415 moves to drive the third rotating member 60414 and the slider 60413 at the bottom of the third rotating member 60414 to move, and the slider 60413 moves to stretch the spring 60412, thereby The installed cling film roll tube 12 is tightened to limit the position, and the user controls the moving position of the sliding rod 705 to control the moving distance of the protrusion 7061 inside the limit installation roller assembly 604, which is convenient for limiting and fixing the cling film roll tube 12 of different specifications, improving the stability when the cling film is rolled up, and avoiding the situation that the cling film roll tube 12 cannot be rolled up due to a gap between the cling film roll tube 12 and the limit installation roller assembly 604 after installation. At the same time, when replacing the cling film roll tube 12, the protrusion 7061 is away from the top plate 6046, When the top plate 6046 loses its thrust, the spring 60412 releases its pulling force to pull back the slider 60413 and the third rotating member 60414, the second connecting rod 60415 and the fourth rotating member 60416 on the slider 60413, thereby pulling the arc-shaped top block 60410 back into the through opening 6042, so that the arc-shaped top block 60410 cancels the limit on the cling film roll 12, making it easier for the user to take it out. By limiting the linkage between the roller assembly 604 and the sleeve 706, there is no need to additionally set up a drive for the limiting device, thereby improving the practicality of the device.

[0051] The above are only preferred specific implementation modes of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical solutions and inventive concepts of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
