Description

Technical Field

[0001] This utility model relates to the field of plastic film recycling production technology, and in particular to a plastic film recycling traction device. Background Technology

[0002] In the process of producing plastic film using the casting method, the width of the film is determined by the width of the casting die. Preparing casting dies of various sizes in advance is costly, and replacing casting dies is cumbersome, requiring significant time for adjustment after installation. Therefore, to meet the specified size requirements of plastic film, the plastic is typically trimmed during production to obtain a finished film of the specified width. Trimming the plastic film generates waste film, which can be recycled and remelted into granules to achieve waste reuse, reduce material waste, and save costs. Current film recycling processes typically involve manually, robotically, via conveyor belts, or traction equipment to feed waste into the melting and granulation recycling port. This is inefficient and poses certain safety hazards, and the process of discharging waste can also cause film scattering, affecting the cleanliness of the surrounding environment.

[0022] Plastic film waste is generated after trimming. This waste film can be recycled and remelted into granules to achieve waste reuse, reduce material waste, and save costs. Some of this waste film is shredded into film fragments and then fed into the melting and granulation recycling port by hand, robotic arms, or conveyor belts. However, this method is inefficient and poses certain safety hazards. Other waste film is rewound into rolls for later collection, storage, or reuse. For the reuse of these rolls, current technology generally involves manually or using traction equipment to unwind the single rolls and guide them into the melting and granulation equipment. However, existing traction equipment is inefficient.

[0023] Reference Figures 1 to 4 This utility model provides a plastic film recycling traction device, including a base 100, an unwinding mechanism and a traction mechanism 300; the unwinding mechanism is disposed on the base 100, and the unwinding mechanism includes a plurality of film unwinding components 200, each film unwinding component 200 including a feeding roller 210, and the plurality of film unwinding components 200 are spaced apart; specifically, the plurality of feeding rollers 210 are spaced apart, and each feeding roller 210 can be fitted with at least one waste film roll to be processed.

[0024] The traction mechanism 300 is mounted on the base 100 and is located on one side of the unwinding mechanism. The traction mechanism 300 can simultaneously traction multiple films 400. Specifically, the traction mechanism 300 can simultaneously traction multiple waste film rolls sleeved on multiple unwinding rollers 210 to unwind the films 400, and enable multiple films 400 to move simultaneously toward the traction mechanism 300.

[0025] By setting up multiple spaced-apart feeding rollers 210, each of which can be fitted with a roll of waste film to be processed, the traction mechanism 300 can simultaneously traction the waste film rolls on multiple feeding rollers 210. This allows multiple sheets of film 400 to be continuously and coordinatedly tractioned and fed into the melting and granulation equipment for processing within the same time. Maintaining an appropriate distance between the multiple feeding rollers 210 ensures that the waste film rolls on adjacent feeding rollers do not interfere with or entangle each other during the unwinding operation of each waste film roll, effectively avoiding downtime caused by film 400 overlap or friction, and improving the continuity and stability of equipment operation. This not only achieves synchronous unwinding and traction feeding of multiple rolls of waste film, significantly increasing the processing capacity of film 400 per unit time, but also significantly improves traction efficiency by processing multiple rolls simultaneously, thereby effectively improving the overall processing efficiency of the film 400 recycling and granulation process, demonstrating good practicality and economic benefits.

[0026] According to some embodiments of this application, refer to Figure 2 Multiple film unwinding assemblies 200 are arranged at intervals along a straight line. Specifically, the traction mechanism 300 is located behind the unwinding mechanism, and the traction mechanism 300 and the multiple film unwinding assemblies 200 are arranged on the same straight line. The traction mechanism 300 can simultaneously pull one end of the waste film rolls on multiple film unwinding assemblies 200 from front to back, unwinding the film 400 of the waste film rolls, and can simultaneously pull and unwind multiple films 400, which can effectively reduce the traction force requirement of the traction mechanism 300.

[0027] Furthermore, referring to Figure 2 The feeding rollers 210 of the multiple film feeding assemblies 200 are arranged parallel to each other and spaced apart. Specifically, the axial direction of the feeding rollers 210 of the multiple film feeding assemblies 200 is perpendicular to the straight direction of the multiple film feeding assemblies 200 arranged at intervals, which can further reduce the traction force requirement of the traction mechanism 300 and reduce the shaking of the film feeding assembly 200 during traction operation.

[0028] According to some embodiments of this application, refer to Figure 2Each film feeding assembly 200 also includes two opposing support seats 220, which are respectively connected to the two ends of the corresponding feeding roller 210 and are rotatably connected to the corresponding feeding roller 210. The two support seats 220 are used to support the feeding roller 210 and allow the feeding roller 210 to rotate on them.

[0029] Furthermore, referring to Figure 3 The support base 220 is equipped with a rolling module 230, which is rotatably connected to the feed roller 210. Specifically, the rolling module 230 is located on the upper side of the support base 220, and the feed roller 210 can be placed on the rolling module 230 from top to bottom. By using the rolling module 230, the frictional force when the feed roller 210 rotates relative to the support base 220 can be reduced, thereby improving the efficiency of unwinding the waste film roll and further reducing the traction force requirement of the traction mechanism 300.

[0030] Furthermore, referring to Figure 3 The rolling module 230 includes two rollers 231 arranged opposite to each other. The two rollers 231 are respectively arranged below the opposite sides of the feeding roller 210 in the radial direction, and the two rollers 231 together support the feeding roller 210.

[0031] It is understood that in some other embodiments, the rolling module 230 may also be a crescent-shaped roller bearing.

[0032] It is understood that, in some other embodiments, reference is made to... Figure 2 The feeding roller 210 is provided with multiple spacer rings 211. Multiple waste film rolls can be sleeved on the feeding roller 210 along its axial direction. One waste film roll is placed between two adjacent spacer rings 211. At this time, the spacer rings 211 play the role of blocking the two adjacent waste film rolls, preventing the two adjacent waste film rolls from sticking together during the traction of the film 400, so that each waste film roll can rotate at the most appropriate angular velocity without interfering with each other.

[0033] According to some embodiments of this application, refer to Figure 4The traction mechanism 300 includes a first traction roller 310, a second traction roller 320, and a drive assembly 330. The first traction roller 310 and the second traction roller 320 are vertically adjacent and spaced apart. The first traction roller 310 and the second traction roller 320 are respectively connected to the drive assembly 330 for transmission. The drive assembly 330 is configured to drive the first traction roller 310 and the second traction roller 320 to rotate in opposite directions. Specifically, the gap between the opposing first traction roller 310 and the second traction roller 320 is used for traction and allows multiple films 400 to pass through. It can be understood that at the gap position between the first traction roller 310 and the second traction roller 320, the peripheral surface of the first traction roller 310 moves from front to back below the gap, and the peripheral surface of the second traction roller 320 moves from front to back above the gap.

[0034] Furthermore, referring to Figure 4 The drive assembly 330 includes a motor 331, a first transmission gear 332, and a second transmission gear 333. The first transmission gear 332 is driven to the output end of the motor 331, and the second transmission gear 333 is driven to the first transmission gear 332. The first transmission gear 332 is driven to one end of the first traction roller 310, and the second transmission gear 333 is driven to one end of the second traction roller 320. The motor 331 drives the first transmission gear 332 to rotate around its own axis; the rotation of the first transmission gear 332 drives the second transmission gear 333 to rotate, and the rotation of the first transmission gear 332 also drives the first traction roller 310 to rotate around its axis; the rotation of the second transmission gear 333 drives the second traction roller 320 to rotate around its axis. The rotation directions of the first transmission gear 332 and the second transmission gear 333 are opposite, therefore the rotation directions of the first traction roller 310 and the second traction roller 320 are opposite.

[0035] Furthermore, referring to Figure 4 Both the first traction roller 310 and the second traction roller 320 have anti-slip textures on their peripheral surfaces. The anti-slip textures can improve the effect of simultaneously traction of multiple films 400 and reduce the slippage of the films 400 relative to the first traction roller 310 or the second traction roller 320.

[0036] Furthermore, referring to Figure 1 and Figure 4The traction mechanism 300 also includes a frame 340, which includes an inlet 341 and an outlet 342. A first traction roller 310, a second traction roller 320, and a drive assembly 330 are all mounted on the frame 340, and both the first traction roller 310 and the second traction roller 320 are positioned between the inlet 341 and the outlet 342. Specifically, the first traction roller 310 is positioned between the inlet 341 and the outlet 342, and the second traction roller 320 is also positioned between the inlet 341 and the outlet 342. During the opposite rotation of the first traction roller 310 and the second traction roller 320, they can traction and drive multiple films 400 to move from the inlet 341 towards the outlet 342, i.e., from front to back, and ultimately simultaneously traction multiple films 400 to the melt granulation equipment.

[0037] Working principle: Multiple waste film rolls are respectively mounted on multiple feeding rollers 210, and then the feeding rollers 210 are mounted on the rolling module 230 of the support base 220; the worker or robot pulls one end of the film 400 wound by the multiple waste film rolls to the traction mechanism 300 and through the gap between the first traction roller 310 and the second traction roller 320; the motor 331 drives the first traction roller 310 and the second traction roller 320 to rotate in opposite directions through the first transmission gear 332 and the second transmission gear 333 respectively, driving the multiple films 400 to be pulled and unwound at the same time; the first traction roller 310 and the second traction roller 320 cooperate to drive the multiple films 400 to move from the feed port 341 of the frame 340 to the discharge port 342, that is, from front to back, and finally can simultaneously pull the multiple films 400 into the melt granulation equipment.
