[0016] Compared with the prior art, the present invention provides a winding device for packaging material production, which has the following beneficial effects:

[0017] 1. The present invention is provided with a shrinking component. First, the packaging material is placed on the device plate. After the packaging material is wrapped, the pull ring is grasped and the movable plate slides on the inner wall of the connecting sleeve to rotate the clamping plate. The clamping plate is rotated to the surface of the sliding box by grasping the two pull rings. When the fixed plate moves to the surface of the sliding box, the clamping plate is first moved by contacting the friction plate with the surface of the clamping box. The position of the fixed plate on the clamping box is determined according to the volume of the packaging material after winding. When it moves to the required position, the pull ring is pulled to push the connecting block into the clamping hole for connection. By providing this component, packaging materials of different quantities and volumes can be compressed and packaged after winding.

[0018] 2. The present invention is provided with a contraction arc plate and a reset block. During the connection process, the surface of the connecting box will squeeze the air bag, squeezing the gas in the air bag into the expansion ring. After absorbing the gas, the expansion ring will expand and stretch upward, and then the impact block on the top of the expansion ring will impact the pressing plate. The impacted pressing plate will squeeze the connecting ring at the bottom, thereby pressing the moving block downward into the air pressure groove, and pushing the adjusting block to slide in the air pressure groove through the moving block. After being pushed, the adjusting block presses the clamping rod downward to clamp and cover the fixed plate with the contraction arc plate on its surface, and finally fixes it with the reset block and the surface of the hook block. By providing this component, the splint and the sliding box surface can be more firmly connected to prevent the splint from being separated from the sliding box surface during the process of moving the packaging material up and down.

[0019] 4. The present invention is provided with a winding component, and the rotating column is rotated to move the holding plate downward. After the cloth is lowered, it contacts the surface of the packaging material. Since the top distribution of the clamping block and the surface of the magnetic block are both made of magnetic materials, the two form a magnetic field so that they attract each other and enter the inside of the clamping ring through the top part of the clamping block and are magnetically connected to the magnetic block. The clamping ring moves downward through contact to generate a magnetic connection with the surface of the magnetic block, and the cloth roll is clamped by the clamping ring. By providing this component, the cloth roll can be quickly used to quickly reel up the packaging material.

[0020] 4. The present invention is provided with a compression component and a crushing component. When the crushing component is used to squeeze the packaging material in the roll of cloth, the packaging material will contact and collide with the rolling plate to cause it to move in the roll of cloth. In the process of the crushing component compressing the packaging material, the air in the roll of cloth will be squeezed and discharged into the ventilation groove and discharged outward through the air outlet cavity. By providing this component, the air in the roll of cloth can be squeezed and discharged outward more quickly. BRIEF DESCRIPTION OF THE DRAWINGS
