Description

Technical Field

[0001] This utility model relates to the field of PET film production technology, specifically to a PET film slitting waste recycling device. Background Technology

[0002] PET film is a type of packaging film with relatively comprehensive performance. Before use, it needs to be cut into the appropriate size using slitting equipment. Excess material after slitting PET film needs to be recycled.

[0003] Publication No. CN220218759U discloses a PET film slitting device. This device moves a protrusion to one side by rotating a bolt. During this movement, a support plate moves downwards, preventing the buffer anti-slip pad on the connecting plate from tightly contacting the horizontal plate. Then, the hollow sliders are moved, changing the distance between the cutting devices at the lower ends of the two hollow sliders. Rotating the bolt in the opposite direction causes the buffer anti-slip pad to contact and press against the horizontal plate, thus fixing the position of the cutting device and ultimately changing the width of the PET film to be cut. This device allows adjustment of the distance between the cutting devices to cut PET films of different widths. However, this patent still has the following problems in practical use:

[0004] This device moves the protrusion to one side by rotating the bolt, causing the support plate to move downwards. This prevents the buffer anti-slip pad on the connecting plate from tightly contacting the horizontal plate. Then, the hollow slider is moved, changing the distance between the cutting devices at the lower ends of the two hollow sliders. Finally, the bolt is rotated in the opposite direction, causing the buffer anti-slip pad to press and fix against the horizontal plate, thus fixing the position of the cutting device. When this device cuts PET film, the film strips on both sides may be uneven after cutting, even though the PET film between the cutting devices meets the requirements. Therefore, workers need to collect the leftover material. However, this device does not have a leftover material collection function, causing the leftover material generated from PET film cutting to accumulate on the workbench and other parts. As the leftover material increases, it may get between some moving parts of the equipment, causing the equipment to jam and be damaged, which will cause inconvenience to the workers.

[0005] A waste material recycling device for PET film slitting is proposed to solve the problems mentioned above. Utility Model Content

[0006] The purpose of this invention is to provide a waste material recycling device for PET film slitting, to solve the problem mentioned in the background art. This device uses a rotating bolt to move a protrusion to one side, causing the support plate to move downwards, preventing the buffer anti-slip pad on the connecting plate from tightly contacting the horizontal plate. Then, the hollow slider is moved, changing the distance between the cutting devices at the lower ends of the two hollow sliders. The bolt is then rotated in the opposite direction to press and fix the buffer anti-slip pad against the horizontal plate, thus fixing the position of the cutting device. However, when slitting PET film, this device may result in uneven film strips on both sides after slitting, even though the PET film specifications between the cutting devices meet the requirements. Therefore, workers need to recycle the waste material. However, this device lacks a waste material recycling function, causing waste material generated during PET film slitting to accumulate on the worktable and other areas. As the waste material increases, it may enter between moving parts of the equipment, leading to jamming and damage.

[0007] To achieve the above objectives, the present invention provides the following technical solution: a PET film slitting waste recycling device, comprising a recycling bin, a workbench on one side of the recycling bin, and a slitting machine on the top of the workbench; a winding mechanism is provided inside the recycling bin, and a connecting component is provided between the recycling bin and the workbench;

[0008] The winding mechanism includes a first extrusion roller and a second extrusion roller, which are rotatably connected to the upper interior of the recycling bin. A limit sleeve is fixedly installed on one side of the top of the recycling bin, and a limit rod is rotatably connected inside the limit sleeve. A first conical tooth is fixedly installed at one end of the first and second extrusion rollers, and a second conical tooth is symmetrically fixedly installed at both ends of the limit rod. A motor is fixedly installed at the end of the second extrusion roller away from the limit sleeve. A winding roller is rotatably connected inside the recycling bin. A first sprocket is fixedly installed at one end of the first extrusion roller, and a second sprocket is fixedly installed at one end of the winding roller. A chain meshes between the first and second sprockets. A mounting plate is inserted into one side of the bottom of the recycling bin.

[0009] Preferably, a fixed box is fixedly installed inside the mounting plate, and fixed rods are symmetrically fixedly connected inside the fixed box. A movable frame is slidably connected to the outside of the fixed rods, and one end of the movable frame passes through the fixed box and is slidably connected to the fixed box. A first retraction spring is sleeved on the outside of the fixed rods. Insert plates are symmetrically slidably connected between the fixed box and the mounting plate. Movable rods are symmetrically rotatably connected to both sides of the movable frame, and the end of the movable rod away from the movable frame is rotatably connected to the insert plate. Slots are symmetrically opened inside one side of the recycling bin, and the insert plates are inserted into the slots.

[0010] Preferably, the connecting assembly includes a limiting box, which is symmetrically embedded on one side of the top of the workbench. A limiting plate is fixedly installed on the side of the recycling bin near the workbench. A limiting groove is opened on one side of the workbench, and the limiting plate is inserted into the limiting groove. A pull rod is slidably connected inside the limiting box, and a pull plate is fixedly installed on the outside of the pull rod. A fixing tube is symmetrically fixedly installed on the top side of the inside of the limiting box. A squeezing rod is slidably connected to the lower inside of the fixing tube. A second contraction spring is provided inside the fixing tube. A moving plate is fixedly connected to the bottom of the pull rod. A sliding groove is symmetrically opened inside the side of the workbench near the limiting box. The moving plate is disposed inside the sliding groove and slidably connected to the sliding groove. A positioning block is welded to the bottom of each moving plate. A positioning groove is opened on the top of each limiting plate, and the positioning block is inserted into the positioning groove.

[0011] Preferably, a protective shell is fixedly installed on the side of the recycling bin near the limiting sleeve.

[0012] Preferably, one side of the motor is fixedly connected to the recycling bin.

[0013] Preferably, the bottom of the extrusion rod is fixedly connected to the pull plate.

[0014] Preferably, the first conical tooth and the second conical tooth are engaged in a meshing connection.

[0015] Compared with the prior art, the beneficial effects of this utility model are as follows: The PET film slitting waste material recycling device specifically includes the following: A motor drives the rotation of the second extrusion roller, the rotation of the first conical tooth drives the rotation of the second conical tooth, and the rotation of the second conical tooth drives the limiting rod to engage and rotate inside the limiting sleeve. At this time, the first and second extrusion rollers run relative to each other, using their rotation to compress the PET film waste material. Through the cooperation between the first sprocket, the second sprocket, and the chain, the rotation of the winding roller is driven, and the rotation of the winding roller winds up the flattened PET film. This achieves the effect of quickly collecting the waste material after PET film slitting. The compression of the PET film by the first and second extrusion rollers effectively reduces the volume of the PET film waste material. This significantly improves the efficiency of subsequent PET film winding, avoids uneven winding of PET film during recycling, and achieves the effect of recycling PET film scraps while slitting. It also greatly enhances the flexibility of the device during use. When the operator inserts the limiting plate into the limiting groove, they pull two sets of levers to slide inside the limiting box. The movement of the levers drives the movement of the pulling plate, which in turn drives the extrusion rod to slide inside the fixed tube. At this time, the second contraction spring is compressed and contracts. Using the tension generated by the second contraction spring, multiple sets of positioning blocks can be inserted into the positioning groove, thus achieving the effect of quickly fixing the limiting plate. This facilitates the rapid assembly and disassembly of the recycling box by the operator, allowing for selection of installation methods based on the actual use of the PET film slitting equipment, greatly improving the flexibility of the device during use.

[0016] 1. The motor drives the second extrusion roller to rotate, which in turn drives the first conical tooth to rotate, which in turn drives the second conical tooth to rotate. The second conical tooth then causes the limiting rod to engage and rotate inside the limiting sleeve. At this time, the first and second extrusion rollers run relative to each other, using their rotation to compress the PET film residue. The rotation of the first extrusion roller also drives the rotation of the first sprocket. Through the cooperation between the first sprocket, the second sprocket, and the chain, the winding roller is driven to rotate, winding up the flattened PET film. Finally, the operator pulls the mounting plate out of the pre-reserved slot on one side of the recycling bin, and then uses a knife to cut the wound PET film. The cut PET film is then removed, thus achieving the effect of quickly collecting the residue after PET film cutting. The compression of the PET film by the first and second extrusion rollers... This device effectively reduces the volume of leftover PET film, significantly improving subsequent PET film winding efficiency and preventing uneven winding during PET film recycling. It achieves simultaneous PET film cutting and recycling, greatly enhancing the flexibility of the device and providing convenience for operators. Operators insert the mounting plate into a pre-reserved slot on one side of the recycling bin. The moving frame slides between the fixed box and the fixed rod, compressing the first contraction spring. The movement of the moving frame drives the movement of two sets of movable rods. The rotation of the movable rods pulls the insert plate inside the fixed box. The operator then releases the moving frame, utilizing the restoring property of the first contraction spring to rotate the movable rod and push the insert plate, allowing it to engage with the slot. This enables quick installation and removal of the mounting plate, facilitating the recycling of PET film wrapped around the winding roller and significantly improving the efficiency of PET film waste recycling.

[0017] 2. The worker inserts the limiting plate into the limiting groove. Then, the worker pulls two sets of levers, which slide inside the limiting box. The movement of the levers moves the pulling plate, which in turn moves the squeezing rod inside the fixed tube. At this point, the second contraction spring is compressed, and the movement of the levers causes the moving plate to slide inside the slide groove. The worker then releases the levers, and the tension generated by the second contraction spring allows multiple positioning blocks to engage with the positioning groove, thus quickly fixing the limiting plate. This facilitates rapid assembly and disassembly of the recycling bin, allowing workers to select the appropriate installation method based on the actual usage of the PET film slitting equipment. This greatly improves the flexibility of the device and provides convenience for workers. Attached Figure Description

This greatly improves the flexibility of the device during use and brings convenience to the staff.

[0029] Working principle: Before using this PET film slitting waste recycling device, it is necessary to check the overall condition of the device to ensure it can operate normally. Figure 1 - Figure 5As shown, the PET film is cut by the slitting machine 102. The worker then passes the remaining material from both sides of the cut PET film through the recycling bin 1 and winds it onto the surface of the take-up roller 208. The worker then starts the motor 207, which drives the second extrusion roller 202 to rotate. The rotation of the second extrusion roller 202 drives the rotation of the first conical tooth 205, which in turn drives the rotation of the second conical tooth 206. The rotation of the second conical tooth 206 causes the limiting rod 204 to engage and rotate inside the limiting sleeve 203. At this time, the first extrusion roller 201 and the second extrusion roller 202 move relative to each other, utilizing the rotation of the first extrusion roller 201 and the second extrusion roller 202 to remove the remaining PET film. The material is compressed by extrusion. The rotation of the first extrusion roller 201 drives the rotation of the first sprocket 209. Through the cooperation between the first sprocket 209, the second sprocket 210, and the chain 211, the rotation of the winding roller 208 is driven. The rotation of the winding roller 208 winds up the flattened PET film. Finally, the worker pulls the mounting plate 212 out of the pre-reserved slot on one side of the recycling box 1, and then uses a knife to cut the wound PET film. Finally, the cut PET film is removed, thus achieving the effect of quickly collecting the remaining material after PET film cutting. The compression of the PET film by the first extrusion roller 201 and the second extrusion roller 202... The pressure effectively reduces the volume of PET film residue, greatly improving the subsequent PET film winding efficiency and avoiding uneven winding during PET film recycling. It achieves the effect of simultaneously cutting and recycling PET film residue, significantly increasing the flexibility of the device and providing convenience for operators. The operator inserts the mounting plate 212 into the pre-reserved slot on one side of the recycling bin 1. At this time, the operator pulls the moving frame 215 to slide between the fixed box 213 and the fixed rod 214. The first contraction spring 216 is compressed and contracts. The movement of the moving frame 215 drives the movement of the two sets of movable rods 218. The rotation of the movable rods 218 pulls the insert plate 217 in the fixed box 213. 13. The internal sliding mechanism is then activated by the worker releasing the moving frame 215. Utilizing the reset property of the first contraction spring 216, the movable rod 218 rotates, pushing the insertion plate 217 to move. This allows the insertion plate 217 to be inserted into the slot 219, enabling quick installation and removal of the mounting plate 212. This facilitates the recycling of the PET film wrapped around the surface of the take-up roller 208, greatly improving the efficiency of PET film waste recycling and providing convenience for workers. The protective shell 220 design prevents external impurities from adhering to the gears, extending the service life of the equipment's transmission structure and enhancing its practicality for workers.

[0030] The worker inserts the limiting plate 302 into the limiting groove 303. At this time, the worker pulls the two sets of pull rods 304 to slide inside the limiting box 301. The movement of the pull rods 304 drives the pull plate 305 to move. The movement of the pull plate 305 drives the squeezing rod 307 to slide inside the fixed tube 306. At this time, the second contraction spring 308 is compressed and contracted. The movement of the pull rods 304 drives the moving plate 309 to slide inside the slide groove 310. Then, the worker releases the pull rods 304. Using the tension generated by the second contraction spring 308, multiple sets of positioning blocks 311 can be inserted into the positioning groove 312, thereby achieving the effect of quickly fixing the limiting plate 302. This facilitates the worker's quick assembly and disassembly of the recycling box 1, and allows the worker to select the installation according to the actual use of the PET film slitting equipment. This greatly improves the flexibility of the device during use and brings convenience to the worker.
