Abstract
Description
Technical Field
[0001] This utility model belongs to the field of sheet processing technology, and in particular relates to a PET sheet slitting machine with waste recycling. Background Technology
[0002] According to the published patent CN212374542U, a slitting machine capable of simultaneously recycling waste materials is described. The slitting assembly further includes a pressure regulating component, which comprises an adjusting block, an adjusting screw, a trapezoidal pressure plate, and a circular shaft sealing plate. The adjusting block is mounted on the second vertical plate. The adjusting screw longitudinally passes through the adjusting block and is threadedly connected to it. The lower end of the adjusting screw contacts but is not connected to the upper end of the trapezoidal pressure plate. The circular shaft sealing plate is located at both ends of the upper roller, and the lower end of the trapezoidal pressure plate is connected to the circular shaft sealing plate. Through the provided waste recycling mechanism, such as a flat scraper, it can simultaneously recycle slitting waste PET sheets and the separated backing paper from double-sided tape, effectively reducing resource waste and lowering production costs to some extent. Furthermore, the pressure regulating component allows for convenient adjustment of the pressure during pressing and slitting, facilitating the production requirements of different product specifications and improving the machine's applicability. However, the following shortcomings still exist:
[0003] After completion, the above equipment simply processes and slits the wood. However, since finished products and waste are generated during the board processing, if the dimensions of the finished products and waste products are too similar, some finished products may be mistakenly classified into the waste area, resulting in material waste.

A second hollow rod is rotatably connected to the outer wall of the other end of the connecting block. A support rod is slidably connected to the inner walls of both the first and second hollow rods. A support block is rotatably connected to the outer wall of the support rod. A recycling mechanism is provided on the outer wall of the base.
[0008] Furthermore, a first damper is fixedly connected to the outer wall of the connecting block, the outer wall of the first damper is fixedly connected to the inner wall of the light-shielding box, a first spring is fixedly connected to the outer wall of the first damper, the outer wall of the first positioning block is fixedly connected to the inner wall of the light-shielding box, the outer wall of the second hollow rod is rotatably connected to the inner wall of the first positioning block, and the outer wall of the connecting block is slidably connected to the inner wall of the light-shielding box.
[0009] Furthermore, the recycling mechanism includes a fixed block, the outer wall of which is fixedly connected to the outer wall of the base, a motor is fixedly connected to the inner wall of the fixed block, the output end of the motor is fixedly connected to a connecting shaft via a coupling, and a first pulley is fixedly connected to the outer wall of the connecting shaft.
[0010] Furthermore, the outer wall of the first pulley is rotatably connected to the outer wall of the fixed block, the inner wall of the first pulley is driven by a belt, the outer wall of the belt away from the connecting shaft is driven by a second pulley, the outer wall of the second pulley is fixedly connected to a first connecting shaft, and the outer wall of the first connecting shaft is rotatably connected to the outer wall of the fixed block.
[0011] Furthermore, a first gear is fixedly connected to the outer wall of the end of the first connecting shaft away from the second pulley, a second gear meshes with the outer wall of the first gear, a second connecting shaft is fixedly connected to the outer wall of the second gear, and the outer wall of the second connecting shaft is rotatably connected to the outer wall of the fixed block.
[0012] Furthermore, rollers are fixedly connected to the outer walls of both the first and second connecting shafts, and a recycling groove is provided on the inner wall of the base. The outer wall of the rollers is rotatably connected to the inner wall of the recycling groove.
[0013] Furthermore, a limiting block is fixedly connected to the outer wall of the connecting shaft, and a plurality of first sliders are slidably connected to the inner wall of the limiting block.

A second damper is fixedly connected to the outer wall of the first slider, and a second spring is fixedly connected to the outer wall of the second damper.
[0015] This utility model has the following beneficial effects:
[0016] 1. This utility model incorporates a bidirectional threaded rod and a moving block. The rotation of the bidirectional threaded rod drives the two moving blocks to move in opposite directions. During the movement of the moving blocks, the first hollow rod rotates around the moving block, while the connecting block moves inside the light-shielding box. This also causes the moving block to move the laser cutting machine at the bottom. This achieves the goal of adjusting the spacing of the laser cutting machine while the moving block is moved by the rotation of the bidirectional threaded rod. This prevents the problem that if the finished products and waste products are too similar in size during the sheet metal processing, some finished products may be mistakenly classified into the waste area, resulting in material waste.
[0017] 2. This utility model incorporates a roller and a rubber roller. Because the first gear meshes with the second gear, the first gear drives the second gear to rotate in the opposite direction, causing the second gear to rotate the second connecting shaft. Since the outer sides of both the first and second connecting shafts are connected to identical rollers, the opposite rotation of the two rollers clamps one end of the waste material and pushes it into the recycling trough below. This achieves the goal of squeezing the waste material into the recycling trough through the opposite rotation of the two rollers, and flattening the waste material through the pressure of the rubber roller. This prevents the waste material from easily curling at the edges due to its own tension after cutting the sheet metal. Curled waste material would occupy extra space in the collection bin, leading to reduced recycling efficiency.
[0018] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.
[0029] Please see Figure 1-6 As shown, this utility model is a PET sheet slitting machine with waste recycling, including a base 1. A light shield 101 is fixedly connected to the top outer wall of the base 1 to block the strong light emitted by the laser cutting machine 205 when cutting objects.
[0030] The inner wall of the light-shielding box 101 is provided with a cutting mechanism 2. The cutting mechanism 2 includes a knob 201. The outer wall of the knob 201 is rotatably connected to the outer wall of the light-shielding box 101. A bidirectional threaded rod 202 is fixedly connected to the outer wall of the knob 201. A moving block 203 is threadedly connected to the outer wall of the bidirectional threaded rod 202. A first positioning block 204 is rotatably connected to the outer wall of the bidirectional threaded rod 202. The rotation of the bidirectional threaded rod 202 pushes the two moving blocks 203 to move in opposite directions, while the first positioning block 204 limits the movement range of the moving blocks 203. The bottom outer surface of the first positioning block 204 and the moving block 203 are connected. Laser cutting machines 205 are fixedly connected to the walls. The movement of the moving block 203 drives the two laser cutting machines 205 to move. Since the first positioning block 204 cannot move, the position of the laser cutting machine 205 at the bottom of the first positioning block 204 is fixed. Several first hollow rods 206 are rotatably connected to the inner wall of the moving block 203. A connecting block 208 is rotatably connected to the outer wall of one end of the first hollow rod 206 away from the moving block 203, and a second hollow rod 207 is rotatably connected to the outer wall of the other end of the connecting block 208. The first hollow rods 206 rotate around the interior of the moving block 203. While rotating, the connecting block 208 is moved, causing the second hollow rod 207 to rotate around the first positioning block 204. Support rods 209 are slidably connected to the inner walls of both the first hollow rod 206 and the second hollow rod 207. A support block 210 is rotatably connected to the outer wall of the support rod 209. The rotation of the first hollow rod 206 and the second hollow rod 207 pushes the support rod 209 to rotate around the support block 210, thus supporting the rotation of the first hollow rod 206 and the second hollow rod 207 using the support rod 209. A recycling mechanism 3 is provided on the outer wall of the base 1. A first damper 211 is fixedly connected to the outer wall of the connecting block 208. The outer wall of the first damper 211 is fixedly connected to the inner wall of the light-shielding box 101. A first spring 212 is fixedly connected to the outer wall of the first damper 211. The pressure generated when the connecting block 208 moves is relieved by using the first damper 211 and the first spring 212 on the outer side of the connecting block 208. The outer wall of the first positioning block 204 is fixedly connected to the inner wall of the light-shielding box 101. The outer wall of the second hollow rod 207 is rotatably connected to the inner wall of the first positioning block 204. The outer wall of the connecting block 208 is slidably connected to the inner wall of the light-shielding box 101.
[0031] The recycling mechanism 3 includes a fixed block 301. The outer wall of the fixed block 301 is fixedly connected to the outer wall of the base 1. A motor 302 is fixedly connected to the inner wall of the fixed block 301. The motor 302 is started. The output end of the motor 302 is fixedly connected to a connecting shaft 303 via a coupling. A first pulley 304 is fixedly connected to the outer wall of the connecting shaft 303. The outer wall of the first pulley 304 is rotatably connected to the outer wall of the fixed block 301. A belt 305 is driven through the inner wall of the first pulley 304. A second pulley 306 is driven through the outer wall of the end of the belt 305 away from the connecting shaft 303. The first pulley 304 and the second pulley 306 are simultaneously connected by both ends of the belt 305, so that the first pulley 304 and the second pulley 306 rotate simultaneously through the drive of the belt 305. A first connecting shaft 307 is fixedly connected to the outer wall of the second pulley 306. The outer wall of the first connecting shaft 307 is fixedly connected to the inner wall of the fixed block 301. The outer wall of the fixing block 301 is rotatably connected to support the rotation of the second pulley 306. The outer wall of the first connecting shaft 307 away from the second pulley 306 is fixedly connected to the first gear 308. The outer wall of the first gear 308 meshes with the second gear 309. Through the meshing of the first gear 308 and the second gear 309, the first gear 308 drives the second gear 309 to rotate in the opposite direction. The outer wall of the second gear 309 is fixedly connected to the second connecting shaft 310. The outer wall of the second connecting shaft 310 is rotatably connected to the outer wall of the fixing block 301. The outer walls of the first connecting shaft 307 and the second connecting shaft 310 are both fixedly connected to the rollers 311. Through the reverse rotation of the first gear 308 and the second gear 309, the two rollers 311 are driven to rotate in the opposite direction. The inner wall of the base 1 is provided with a recycling groove 312. The outer wall of the rollers 311 is rotatably connected to the inner wall of the recycling groove 312.
[0032] A limiting block 313 is fixedly connected to the outer wall of the connecting shaft 303. A plurality of first sliders 314 are slidably connected to the inner wall of the limiting block 313. A connecting rod 315 is rotatably connected to the inner wall of the plurality of first sliders 314. A second positioning block 316 is rotatably connected to the outer wall of the end of the connecting rod 315 away from the first sliders 314. The rotation of the connecting rod 315 pushes the first sliders 314 to move along the interior of the limiting block 313, while simultaneously pulling down the second positioning block 316, causing the surface of the rubber roller 317 to bend and deform. The outer wall of the second positioning block 316... A rubber roller 317 is fixedly connected, and the outer wall of the rubber roller 317 is fixedly connected to the outer wall of the connecting shaft 303. A second damper 318 is fixedly connected to the outer wall of the first slider 314. The second damper 318 is used to relieve the pressure when the first slider 314 moves. A second spring 319 is fixedly connected to the outer wall of the second damper 318. The second damper 318 is pre-set to automatically stretch the outer second spring 319 when it is pulled outward. The elasticity of the second spring 319 is used to increase the support force of the connecting rod 315 on the rubber roller 317.
[0033] One specific application of this embodiment is:
[0034] When the operator needs to use the equipment, the raw material to be cut is placed on the surface of the base 1, then pushed into the light-shielding box 101. The operator then turns the knob 201 to rotate the bidirectional threaded rod 202 inside the light-shielding box 101. The rotation of the bidirectional threaded rod 202 pushes two moving blocks 203 to move in opposite directions, causing the moving blocks 203 to move the laser cutter 205 at the bottom. During the movement of the moving blocks 203, the first hollow rod 206 rotates around the moving blocks 203, simultaneously causing the connecting block 208 to move inside the light-shielding box 101. The movement of the connecting block 208 compresses the first damper 211 and the first spring 212 inside the light-shielding box 101. The first damper 211 and the first spring 212 absorb the pressure when the connecting block 208 moves. During the movement of the connecting block 208, the second hollow rod 207 will rotate around the first positioning block 204. Since the first positioning block 204 is fixed inside the light-shielding box 101, the rotation of the second hollow rod 207 restricts the movement of the connecting block 208. At the same time, the rotation of the first hollow rod 206 and the second hollow rod 207 will push multiple identical two-pronged support rods 209 to rotate around the same support block 210 simultaneously, and cause the other end of the support rod 209 to move along the inside of the connected first hollow rod 206 or second hollow rod 207, thereby affecting the first hollow rod 206. The rotation of the second hollow rod 207 is supported, and laser cutting machines 205 are fixed at the bottom of both the moving block 203 and the first positioning block 204. The first positioning block 204 cannot move, so the width of the finished product after cutting the raw material can be quickly controlled by adjusting the distance between the moving block 203 and the first positioning block 204. Then, multiple laser cutting machines 205 are started and the raw material is pushed through the light shield box 101 and cut into multiple pieces by the laser cutting machines 205. Since the edges of the raw material after cutting are not wide enough and do not meet the standards, they become waste products. By continuously pushing these waste products, they will be placed on the outside of the rubber roller 317, and the motor 302 is started in advance to drive the connecting shaft 303 to rotate, while driving multiple rubber rollers. Roller 317 rotates, using the friction of its surface to push waste forward. Two identical first pulleys 304 are connected to the outside of connecting shaft 303. The rotation of the first pulleys 304 drives belt 305, which in turn drives a second pulley 306. This belt 305 drives both the second and first pulleys 304 to rotate simultaneously. The rotation of the second pulley 306 then drives the first connecting shaft 307 to rotate, which in turn drives the first gear 308. Since the first gear 308 meshes with the second gear 309, it pushes the second gear 309 to rotate in the opposite direction.The second gear 309 drives the second connecting shaft 310 to rotate. Since the first connecting shaft 307 and the second connecting shaft 310 are simultaneously connected to identical rollers 311 on their outer sides, the opposing rotation of the two rollers 311 clamps one end of the waste product and pushes it into the lower recycling trough 312. During the rotation of the rubber roller 317, the surface of the rubber roller 317 contacts the surface of the waste product. The size of the waste product compresses the rubber roller 317, causing it to deform and pushing multiple second positioning blocks 316 inside the rubber roller 317. The second positioning block 316 drives the connecting rod 315 to rotate around the second positioning block 316, while simultaneously pushing the connecting rod 315 to move inside the limiting block 313. The movement of the connecting rod 315 pulls the second damper 318 to relieve the pressure generated by the movement of the first slider 314. The elasticity of the second spring 319 located on the outside of the second damper 318 pulls the first slider 314 back, thereby increasing the support force of the connecting rod 315 on the rubber roller 317, and thus increasing the squeezing force of the rubber roller 317 on the waste product.
