Description

Technical Field

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

[0002] PVC film, whose main component is polyvinyl chloride, has other components added to enhance its heat resistance, toughness, ductility, etc. The top layer of this surface film is paint, the middle main component is polyvinyl chloride, and the bottom layer is backing adhesive. It is a popular and widely used synthetic material in the world today. PVC film can be divided into PVC soft film and PVC hard film.

[0003] In the prior art, such as Chinese Patent No. CN216727448U, a PVC film shredding device is disclosed, including a box body. An electric telescopic rod is fixedly connected to the left side of the top of the inner cavity of the box body, and a pressure plate is fixedly connected to the bottom of the electric telescopic rod. Heating wires are horizontally fixedly connected to both sides of the inner cavity of the pressure plate. A horizontal plate is fixedly connected to the top of the left side of the inner cavity of the box body, and a third motor is fixedly connected to the left side of the top of the rear side of the box body. This utility model solves the problems of existing PVC film shredding devices, which usually have a relatively simple shredding structure, resulting in poor shredding effect, and often cannot flatten the rolled-up rigid PVC film before shredding, which may affect the shredding effect of the rigid PVC film during use.

[0004] While the above-mentioned solution has the advantages mentioned above, its disadvantages are as follows: Although it can solve the problem of poor shredding effect caused by the simple shredding structure of existing PVC film shredding devices by setting up electric telescopic rods, pressure plates, heating wires, conveyor rollers, shredding rollers, auxiliary blades, cutting blades, driving gears, driven gears, belts, pulleys and controllers, the shredding rollers and cutting blades require separate motors for driving, resulting in higher production costs, a relatively high motor failure rate, and a relatively high frequency of motor maintenance. This necessitates stopping the operation of the shredding device, thus reducing the efficiency of film shredding. Furthermore, it is inconvenient to remove film debris from the bottom of the chamber, which is cumbersome and leads to low efficiency in film debris cleaning. Utility Model Content

[0005] The purpose of this invention is to address the problems in existing technologies where, although existing PVC film shredding devices can achieve good shredding results through the coordinated use of an electric telescopic rod, pressure plate, heating wire, conveyor roller, shredding roller, auxiliary blade, cutting blade, drive gear, driven gear, belt, pulley, and controller, the shredding structure is often too simple, resulting in poor shredding effect. However, the shredding roller and cutting blade require separate motors for driving, leading to high production costs, relatively high motor failure rates, and frequent motor maintenance. This necessitates stopping the shredding device, reducing film shredding efficiency. Furthermore, it is inconvenient to remove film debris from the bottom of the housing, resulting in low efficiency in film debris removal.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a shredding device for PVC film, comprising: a housing, and further comprising:

[0007] A top frame is fixedly connected to the top of the box body. Two shredding rollers are symmetrically rotatably connected to opposite sides of the inner wall of the top frame. A third gear is fixedly connected to one end of each shredding roller, and the teeth of the two third gears mesh. A cylindrical barrel is fixedly connected to the inner wall of the box body. A rotating rod three is rotatably connected to the bottom of the cylindrical barrel. Multiple cutting blades are fixedly connected at equal intervals to the outer surface of the rotating rod three. A bevel gear two is fixedly connected to one end of the rotating rod three. A rotating rod two is rotatably connected to one side of the box body. A bevel gear one is fixedly connected to one end of the rotating rod two. The bevel gear one and bevel gear two mesh with each other. A pulley two is fixedly connected to the other end of the rotating rod two. A pulley one is fixedly connected to one end of one of the shredding rollers. A belt strip is rotatably connected to the outer surfaces of pulley one and pulley two. A motor is fixedly connected to one side of the top frame. The output end of the motor is fixedly connected to the other end of one of the shredding rollers.

[0008] Preferably, the bottom of the top frame is inclined, and the top frame is connected to the box body.

[0009] Preferably, a connecting pipe is fixedly connected to the bottom of the cylinder, and the connecting pipe is connected to the cylinder.

[0010] Preferably, a cylinder is fixedly connected to the side of the box near the bottom, and the cylinder is fixedly connected to the connecting pipe, and the cylinder and the connecting pipe are in communication.

[0011] Preferably, a rotating rod is rotatably connected to the inner wall of the cylinder, the rotating rod is rotatably connected to the box body, and a helical blade is fixedly wound around the outer surface of the rotating rod, the outer surface of the helical blade being rotatably connected to the inside of the cylinder.

[0012] Preferably, a discharge pipe is fixedly connected to the outer surface of the cylinder, and the discharge pipe is connected to the cylinder.

[0013] Preferably, a first gear is fixedly connected to one end of the rotating rod one, and a second gear is fixedly connected to the outer surface of the rotating rod two, with the second gear meshing with the first gear.

[0014] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0015] 1. This utility model uses a controller to start a motor, causing its output shaft to drive one of the shredding rollers and a third gear to rotate. Then, with the meshing of two third gears, the other third gear and the shredding roller can rotate in the opposite direction, shredding the film. The shredded film falls into the inside of a cylindrical drum. Simultaneously, the rotation of one of the shredding rollers drives a first pulley to rotate. Then, with the cooperation of the first pulley, the belt, and the second pulley, the second pulley drives a second rotating rod and a first bevel gear to rotate. Finally, with the meshing of the first and second bevel gears, a third rotating rod and a cutting blade can rotate, performing a secondary shredding process on any insufficiently shredded film, ensuring thorough shredding. This design requires only one motor to drive the shredding roller and the cutting blade, thus reducing the production cost of the device, lowering the failure rate and maintenance frequency, and ultimately improving the efficiency of film shredding.

[0016] 2. In this utility model, the rotation of the second rotating rod drives the second gear to rotate. Then, with the meshing of the second gear and the first gear, the first gear drives the first rotating rod and the spiral blade to rotate. The shredded film inside the cylinder enters the cylinder through the connecting pipe. Through the rotation of the spiral blade, the film fragments are conveyed to the discharge pipe side, so that the film fragments are discharged from the discharge pipe. This makes it easy to discharge the film fragments from the bottom of the box, which is relatively simple and improves the efficiency of film fragment cleaning. Attached Figure Description

However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0025] Examples, such as Figure 1-4 As shown, this utility model provides a shredding device for PVC film, including: a housing 1, and a top frame 2, which is fixedly connected to the top of the housing 1. Two shredding rollers 201 are symmetrically rotatably connected to opposite sides of the inner wall of the top frame 2. A third gear 202 is fixedly connected to one end of each shredding roller 201, and the teeth of the two third gears 202 mesh. A cylinder 209 is fixedly connected to the inner wall of the housing 1. A rotating rod 210 is rotatably connected to the bottom of the cylinder 209. Multiple cutting blades 211 are fixedly connected at equal intervals to the outer surface of the rotating rod 210. One end of the rotating rod 210 is fixedly connected to... A bevel gear 212 is rotatably connected to one side of the housing 1, and a rotating rod 206 is rotatably connected to one end of the rotating rod 206. A bevel gear 208 is fixedly connected to one end of the rotating rod 206, and the bevel gear 208 meshes with the bevel gear 212. A pulley 205 is fixedly connected to the other end of the rotating rod 206. A pulley 203 is fixedly connected to one end of one of the chopping rollers 201. A belt strip 204 is rotatably connected to the outer surfaces of the pulleys 203 and 205. A motor 207 is fixedly connected to one side of the top frame 2, and the output end of the motor 207 is fixedly connected to the other end of one of the chopping rollers 201.

[0026] Furthermore, such as Figure 1-4As shown, the bottom of the top frame 2 is set to be inclined, and the top frame 2 is connected to the box body 1. The above setting makes it convenient for the shredded film to fall downwards.

[0027] Furthermore, such as Figure 1-4 As shown, a connecting pipe 107 is fixedly connected to the bottom of the cylindrical barrel 209. The connecting pipe 107 is connected to the cylindrical barrel 209. Through the above arrangement, the film debris inside the cylindrical barrel 209 can be discharged through the connecting pipe 107.

[0028] Furthermore, such as Figure 1-4 As shown, a cylinder 104 is fixedly connected to one side of the box 1 near the bottom. The cylinder 104 is fixedly connected to the connecting pipe 107, and the cylinder 104 and the connecting pipe 107 are connected. Through the setting of the connecting pipe 107, the film debris inside the cylinder 209 can fall into the cylinder 104.

[0029] Furthermore, such as Figure 1-4 As shown, a rotating rod 101 is rotatably connected to the inner wall of the cylinder 104. The rotating rod 101 is rotatably connected to the housing 1. A spiral blade 106 is fixedly wound around the outer surface of the rotating rod 101. The outer surface of the spiral blade 106 is rotatably connected to the inside of the cylinder 104. By rotating the rotating rod 101, the spiral blade 106 can be driven to rotate, thereby conveying the film debris inside the cylinder 104.

[0030] Furthermore, such as Figure 1-4 As shown, a discharge pipe 105 is fixedly connected to the outer surface of the cylinder 104. The discharge pipe 105 is connected to the cylinder 104. Through the above arrangement, the film debris inside the cylinder 104 can be discharged through the discharge pipe 105.

[0031] Furthermore, such as Figure 1-4 As shown, a first gear 102 is fixedly connected to one end of the rotating rod 101, and a second gear 103 is fixedly connected to the outer surface of the rotating rod 206. The second gear 103 meshes with the first gear 102. With the meshing of the second gear 103 and the first gear 102, when the second gear 103 rotates, it can drive the first gear 102 and the rotating rod 101 to rotate.

[0032] Working principle: In use, the film is fed from the top of the top frame 2, and the controller simultaneously starts the motor 207, causing its output shaft to drive one of the shredding rollers 201 and the third gear 202 to rotate. Then, with the two third gears 202 meshing, the other third gear 202 and the shredding roller 201 can rotate in the opposite direction, shredding the film. The shredded film falls into the inside of the cylinder 209. Simultaneously, the rotation of one of the shredding rollers 201 can drive the pulley 1 203 to rotate. Then, with the cooperation of the pulley 1 203, the belt 204 and the pulley 205, the pulley 205 can drive the rotating rod 206 and the bevel gear 1 208 to rotate. Then, with the meshing of the bevel gear 1 208 and the bevel gear 212, the rotating rod 3 210 and the cutting blade 211 can rotate, performing secondary shredding on the insufficiently shredded film. The film is thoroughly shredded, so that only one motor 207 is needed to drive the shredding roller 201 and the cutting blade 211, thereby reducing the production cost of the device, making the failure rate of the device relatively low, the maintenance frequency relatively low, and thus improving the efficiency of film shredding. Simultaneously, the rotation of the second rotating rod 206 can drive the second gear 103 to rotate. Then, with the meshing of the second gear 103 and the first gear 102, the first gear 102 can drive the rotating rod 101 and the spiral blade 106 to rotate. The shredded film inside the cylinder 209 will enter the inside of the cylinder 104 through the connecting pipe 107. Through the rotation of the spiral blade 106, the film fragments can be conveyed to the discharge pipe 105 side, so that the film fragments are discharged from the discharge pipe 105. This makes it easy to discharge the film fragments from the bottom of the box 1, which is relatively simple and improves the efficiency of film fragment cleaning.
