Description

Technical Field

[0001] This utility model relates to the field of film stretching equipment technology, and in particular to a PVC film stretching processing equipment. Background Technology

[0002] In the production of PVC film, in order to improve the mechanical properties, optical characteristics and functionalization level of PVC film, it is often necessary to perform stretching treatment. The molecular arrangement structure is changed through directional stretching process, thereby optimizing the physical properties.

[0003] Currently, most film stretching machines on the market use screws or other means to fix the two rolls, which are responsible for winding during the film stretching process, to the rotating shaft. After winding is completed, the screws need to be manually removed to remove the rolls from the rotating shaft and replace them. This results in low efficiency in removing and installing the rolls and long waiting times for the film stretching machine. Therefore, the efficiency of film stretching processing needs to be further improved.

[0004] Therefore, a PVC film stretching treatment device is proposed. Utility Model Content

[0005] To address the shortcomings of existing technologies, this invention provides a PVC film stretching processing device, which solves the problems mentioned in the background section.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A PVC film stretching processing device includes an electrical control box. A tray is fixedly installed on the top surface of the electrical control box. Winding mechanisms are respectively provided on the left and right sides of the top surface of the tray. Each winding mechanism includes a fixed plate and a movable plate. The fixed plate is fixedly installed on the top surface of the tray, and the movable plate is movably arranged on the top surface of the tray and is arranged opposite to the fixed plate. A rotating shaft is rotatably installed on the surface of both the fixed plate and the movable plate. A locking block is fixedly installed on the opposite surface of the two rotating shafts. A winding cylinder is slidably engaged on the surface of the two locking blocks. A synchronous moving component is provided on the surface of the left and right movable plates. A sliding drive component for driving the synchronous moving component is provided on the surface of the tray. A second motor for driving the rotating shaft is fixedly installed on the surface of the right fixed plate. A heating mechanism and a stretching mechanism are arranged sequentially from left to right between the two winding mechanisms.

[0008] Preferably, a baffle is fixedly installed on the surface of the rotating shaft, and the baffle protrudes around the perimeter of the locking block.

[0009] Preferably, the locking block is a cross-shaped locking block, and the front and rear sides of the winding cylinder are provided with cross-shaped locking grooves, and the cross-shaped locking block is slidably inserted into the cross-shaped locking grooves.

[0010] Preferably, the synchronous movement component includes a T-shaped slide groove, which is formed on the top surface of the support plate. A slider is slidably mounted on the inner wall surface of the T-shaped slide groove. The slider is fixedly mounted on the bottom surface of the moving plate. The moving plate is slidably arranged along the inner wall surface of the T-shaped slide groove. A connecting plate is fixedly connected to the back of the two moving plates. The length of the slider's movement range is at least 2.5 times the length of the block. The sliding drive component is used to drive the slider to move back and forth.

[0011] Preferably, the sliding drive assembly includes a first motor, which is fixedly mounted on the side of the support plate. A threaded rod is fixedly connected to the output end of the first motor. The threaded rod is rotatably disposed through a T-shaped groove on one side, and the slider on one side is threadedly mounted on the surface of the threaded rod.

[0012] Preferably, the heating mechanism includes a rotatably mounted electric heating roller, which is a hollow cylinder with heating wires uniformly arranged inside; the stretching mechanism includes a stretching roller, the height of which is greater than that of the winding drum and the electric heating roller.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows: When it is necessary to replace the winding cylinder, the sliding drive component drives the synchronous moving component, which in turn drives the two moving plates on the left and right to move back and forth synchronously. This makes it easy for the locking block to leave the surface of the winding cylinder or slide back into the winding cylinder. The two winding cylinders can be quickly removed and the new winding cylinder can be installed and fixed without the aid of tools. Compared with using tools to fix and disassemble the winding cylinder, the efficiency is higher, and the disassembly and assembly of the winding cylinder can be completed quickly, thereby reducing downtime and improving film stretching efficiency.

Winding mechanisms 3 are respectively provided on the left and right sides of the top surface of the tray 2. The winding mechanism 3 includes a fixed plate 301 and a movable plate 302. The fixed plate 301 is fixedly installed on the top surface of the tray 2. The movable plate 302 is movably arranged on the top surface of the tray 2 and is arranged opposite to the fixed plate 301. A rotating shaft 303 is rotatably installed on the surface of both the fixed plate 301 and the movable plate 302. A locking block 304 is fixedly installed on the opposite surface of the two rotating shafts 303. A winding cylinder 4 is slidably engaged on the surface of the two locking blocks 304. A synchronous moving component 5 is provided on the surface of the left and right movable plates 302. A sliding drive component 6 for driving the synchronous moving component 5 is provided on the surface of the tray 2. A second motor 7 for driving the rotating shaft 303 to rotate is fixedly installed on the surface of the right fixed plate 301. A heating mechanism 8 and a stretching mechanism 9 are arranged sequentially from left to right between the two winding mechanisms 3.

[0021] A baffle 305 is fixedly installed on the surface of the rotating shaft 303, and the baffle 305 protrudes around the locking block 304.

[0022] The locking block 304 is a cross-shaped locking block. The front and rear sides of the winding cylinder 4 are provided with cross-shaped slots, and the cross-shaped locking block is slidably inserted into the cross-shaped slots.

[0023] The synchronous moving component 5 includes a T-shaped slide 501, which is formed on the top surface of the support plate 2. A slider 502 is slidably installed on the inner wall surface of the T-shaped slide 501. The slider 502 is fixedly installed on the bottom surface of the moving plate 302. The moving plate 302 is slidably arranged along the inner wall surface of the T-shaped slide 501. A connecting plate 503 is fixedly connected to the back of the two moving plates 302. The length of the moving range of the slider 502 is at least 2.5 times the length of the support plate of the block 304. The sliding drive component 6 is used to drive the slider 502 to move back and forth.

[0024] The sliding drive assembly 6 includes a first motor 601, which is fixedly installed on the side of the support plate 2. A threaded rod 602 is fixedly connected to the output end of the first motor 601. The threaded rod 602 is rotatably arranged through a T-shaped slide groove 501 on one side in a front-back direction, and a slider 502 on one side is threadedly installed on the surface of the threaded rod 602.

[0025] The heating mechanism 8 includes a rotating electric heating roller 10, which is a hollow cylinder with heating wires evenly arranged inside. The stretching mechanism 9 includes a stretching roller 11, the height of which is greater than that of the winding drum 4 and the electric heating roller 10.

[0026] Working principle: The winding drum 4 for winding PVC film is placed between the front and rear clamping blocks 304. Due to the engagement of the clamping blocks 304, the winding drum 4 remains fixed relative to the clamping blocks 304. The output end of the second motor 7 drives the right-side rotating shaft 303 to rotate, which in turn drives the right-side clamping blocks 304 and the winding drum 4 to rotate synchronously. Thus, the PVC film originally wound on the surface of the left-side winding drum 4 is heated by the heating mechanism 8 and stretched by the stretching roller 11 and then wound onto the surface of the right-side winding drum 4, completing the stretching process of the PVC film. When it is necessary to replace the winding drum 4, the sliding drive assembly 6 drives the synchronous moving assembly 5, which drives the left and right moving plates 302 to move backward synchronously. The movement causes the locking block 304, which was originally slidably engaged with the rear side of the winding cylinder 4, to disengage from the surface of the winding cylinder 4. Then, the moving plate 302 continues to move backward, allowing the operator to manually slide the winding cylinder 4 off the surface of the locking block 304 on the front side. Both winding cylinders 4 can be removed simultaneously and quickly without the aid of tools. After the new winding cylinder 4 is slidably engaged with the surface of the locking block 304 on the front side, the moving plate 302 is pushed forward by the synchronous moving component 5, causing the locking block 304 on the rear side to also slide into the rear side of the winding cylinder 4, thus completing the installation of the winding cylinder 4. Compared with using tools to fix and disassemble the winding cylinder 4, this method is more efficient and can quickly complete the installation and disassembly of the winding cylinder 4, thereby reducing downtime and improving film pulling efficiency.

[0027] Specifically, the baffles 305 provided around the protruding card block 304 limit the winding cylinder 4 that is slidably mounted on the surface of the card block 304, preventing the winding cylinder 4 from sliding back and forth on the surface of the card block 304, thereby ensuring that the PVC film can be evenly wrapped around the surface of the winding cylinder 4 during winding.

[0028] Specifically, the cross-shaped slot and the cross-shaped block are used in conjunction to ensure that the winding drum 4 is evenly stressed when it is engaged on the surface of the block 304, thus ensuring that the winding drum 4 and the block 304 can rotate synchronously.

[0029] Specifically, when the slider 502 on one side moves back and forth under the action of the sliding drive assembly 6, it will drive the moving plate 302 on the other side to move back and forth through the moving plate 302 fixedly connected to the slider 502 and the connecting plate 503 fixedly connected to the two moving plates 302. At this time, the slider 502 on the other side slides in the T-shaped slide groove 501, realizing the synchronous back and forth movement control of the two moving plates 302 on the left and right.

[0030] Specifically, the output end of the first motor 601 drives the threaded rod 602 to rotate, causing the slider 502, which is threaded onto the surface of the threaded rod 602, to move back and forth along the inner wall surface of the T-shaped groove 501, thereby realizing the back and forth movement control of the moving plate 302.

[0031] Specifically, the heating roller 10 is heated by heating wire, which heats the PVC film attached to the heating roller 10, improves the flexibility and toughness of the PVC film, and makes it easier to be stretched when passing through the stretching roller 11 and less prone to breakage, thereby improving stretching efficiency and stretching effect.
