Description

Technical Field

[0001] This utility model belongs to the field of PE film production technology, specifically relating to a PE film dispensing mechanism. Background Technology

[0002] PE film is the simplest high-molecular organic compound in terms of structure and is one of the most widely used polymer materials in the world today. Blow molding is a common method for producing PE film. First, plastic particles are heated to a molten state, then extruded into a mold to form a thin-walled tube. Then, compressed air is used to inflate the thin-walled tube in the mold into a thin film tube. After the thin film tube is cooled and shaped by an air ring, it is flattened to form a laminated film. Finally, the film is unwound and wound up.

[0003] Chinese Patent CN217293440U discloses a PE film dispensing mechanism, including a frame, an active clamping arm, and a driven clamping arm. The active and driven clamping arms are movably connected to the frame via a drive assembly. A film dispensing roller rotation assembly is fixed to the active and driven clamping arms. Positioning frames are installed at both ends of the frame. The drive assembly includes a telescopic cylinder fixed to the top of the frame. The telescopic end of the telescopic cylinder is fixed to a first slider. The first slider is slidably connected to a groove opened in the frame. An active clamping arm is installed at the bottom of the first slider. A slide is symmetrically installed at the bottom of the frame. A second slider is slidably connected to both sides of the slide, and the second sliders on both sides of the slide are respectively fixed to the active and driven clamping arms. A gear disk is rotatably connected to the center of the bottom of the frame. An active rack that meshes with one side of the gear disk is installed on the top side of the active clamping arm, and a driven rack that meshes with the other side of the gear disk is installed on the top side of the driven clamping arm.

[0004] Regarding the aforementioned related technologies, the inventors have discovered at least the following problems: During the production of PE film, due to its inherent physical properties and the mechanical stress during the production process, the surface of the PE film is prone to wrinkles. If the uneven PE film is directly wound up, it will easily affect the subsequent processing quality of the PE film. Utility Model Content

Detailed Implementation

[0020] The present invention will be further described below with reference to the embodiments.

[0021] The following embodiments are used to illustrate the present invention, but should not be used to limit the scope of protection of the present invention. The conditions in the embodiments can be further adjusted according to specific conditions, and simple improvements to the method of the present invention under the premise of the concept of the present invention are all within the scope of protection claimed by the present invention.

[0022] Please see Figure 1-3 This utility model provides a PE film dispensing mechanism, including a frame 1, a winding mechanism 2, and a leveling mechanism 3. The frame 1 includes a base 11 and side seats 12 fixedly connected to both sides of the base 11. The winding mechanism 2 includes a support seat 21 slidably installed between the two side seats 12, a support arm 22 rotatably installed on the support seat 21, and a first adjusting member 23 for adjusting the distance between the two support seats 21. A first motor 24 for driving the support arm 22 to rotate is fixedly installed on one of the support seats 21. With the setting of the winding mechanism 2, when dispensing the film, the roller for winding the PE film is placed between the two support arms 22. The first adjusting member 23 is activated to adjust the distance between the two support seats 21, so that the two support arms 22 are respectively pressed against the two ends of the roller. Then, the first motor 24 can be activated to drive the support arm 22 to rotate, so that the support arm 22 drives the roller to rotate, thereby winding the PE film.

[0023] Specifically, the first adjusting component 23 includes a bidirectional screw 231 rotatably mounted between the two side seats 12 and a second motor 232 for driving the bidirectional screw 231 to rotate. Two support seats 21 are respectively sleeved on both sides of the bidirectional screw 231 and threadedly connected to the bidirectional screw 231. The first adjusting component 23 also includes a guide rod 233 fixedly mounted between the two side seats 12. The support seats 21 are slidably sleeved on the guide rod 233. By setting the first adjusting component 23, the second motor 232 can be started to drive the bidirectional screw 231 to rotate, so that the bidirectional screw 231 drives the two support seats 21 to move relative to or opposite to each other along the guide rod 233, thereby adjusting the distance between the two support arms 22, which is convenient for installing rollers of different lengths.

[0024] Specifically, the leveling mechanism 3 includes a guide roller 31 rotatably mounted between two side seats 12, a leveling roller 32 disposed on one side of the guide roller 31, and a second adjusting member 33 for adjusting the distance between the leveling roller 32 and the guide roller 31. With the setting of the leveling mechanism 3, when the film is exiting, the PE film can pass between the guide roller 31 and the leveling roller 32, and then the PE film is wound onto the roller. The distance between the leveling roller 32 and the guide roller 31 is adjusted by the second adjusting member 33, so that the leveling roller 32 cooperates with the guide roller 31 to squeeze the PE film, eliminate wrinkles on the surface of the PE film, level the PE film and then rewind it, so as to avoid affecting the subsequent processing quality of the PE film.

[0025] Specifically, the second adjusting component 33 includes a support shaft 331 rotatably mounted between the two side seats 12 and a third motor 332 for driving the support shaft 331 to rotate. Both ends of the support shaft 331 are fixedly connected to connecting arms 333. The leveling roller 32 is rotatably mounted between the two connecting arms 333. By setting the second adjusting component 33, the third motor 332 can be started to drive the support shaft 331 to rotate, so that the support shaft 331 drives the connecting arms 333 to rotate. The connecting arms 333 drive the leveling roller 32 to move around the support shaft 331 in a circle, thereby facilitating the adjustment of the distance between the leveling roller 32 and the guide roller 31, and facilitating the leveling of PE films of different thicknesses.

[0026] A controller 13 is provided on one side of the side seat 12. The first motor 24, the second motor 232 and the third motor 332 are all electrically connected to the controller 13. The first motor 24, the second motor 232 and the third motor 332 are all controlled by the controller 13.

[0027] The working principle and usage process of this utility model are as follows: First, during film output, the PE film winding roller is placed between the two support arms 22. The second motor 232 can be started to drive the bidirectional screw 231 to rotate, causing the bidirectional screw 231 to drive the two support seats 21 to move relative to or in opposite directions along the guide rod 233. This allows adjustment of the distance between the two support arms 22, ensuring that the two support arms 22 are respectively pressed against both ends of the roller. Then, the PE film can be passed between the guide roller 31 and the leveling roller 32, and then the PE film is wound onto the roller. Finally, the third motor 332 can be started. The support shaft 331 is driven to rotate, which in turn drives the connecting arm 333 to rotate. The connecting arm 333 drives the leveling roller 32 to move around the support shaft 331 in a circular motion. The distance between the leveling roller 32 and the guide roller 31 is adjusted according to the thickness of the PE film. Then, the first motor 24 can be started to drive the support arm 22 to rotate, which in turn drives the roller to rotate and wind up the PE film. The leveling roller 32 works with the guide roller 31 to squeeze the PE film, eliminating wrinkles on the surface of the PE film. The PE film is leveled before being wound up to avoid affecting the subsequent processing quality of the PE film.
