Description

Technical Field

[0001] The present invention relates to the technical field of PVC film waste recycling, and specifically provides a waste recycling machine for calendering treatment of PVC films. Background Art

[0002] PVC films are widely used and have important applications in many fields such as construction, packaging, decoration, and electronics. During the calendering production process of PVC films, a large amount of waste will inevitably be generated. For example, edge materials will be generated when cutting both sides of the PVC film before winding. If these wastes are not recycled, it will not only cause waste of resources, but also increase the costs of enterprises and put pressure on the environment. The waste recycling machine for calendering treatment of PVC films can recycle and reuse the waste generated during PVC calendering treatment, thus avoiding waste of resources. When the existing waste recycling machines for calendering treatment of PVC films are in use, the following technical problems still exist, such as: 1. When the existing waste recycling machines for calendering treatment of PVC films are in use, generally, the waste cannot be completely crushed in one pass. As a result, it is necessary to manually add the waste after one-pass crushing above the crushing structure so that the waste after one-pass crushing is crushed again. This method will increase the labor intensity of workers and has low efficiency. 2. When the existing waste recycling machines for calendering treatment of PVC films are in use, it is not convenient to completely discharge the crushed waste from the recycling machine. This is because after the waste is crushed, some of it will adhere to the inner bottom surface of the recycling machine, resulting in the inability to completely discharge the waste from the recycling machine. Therefore, a waste recycling machine for calendering treatment of PVC films is needed to solve the above problems. Summary of the Invention

[0003] The purpose of the present invention is to provide a waste recycling machine for calendering treatment of PVC films to solve the problems in the above background art that the existing waste recycling machines for calendering treatment of PVC films need to manually add the waste after one-pass crushing to the recycling machine for crushing, which has low efficiency, increases the labor intensity of workers, and is not convenient to completely discharge the crushed waste from the recycling machine.

[0004] To achieve the above purpose, the present invention provides the following technical solutions: A waste recycling machine for calendering treatment of PVC films, comprising a machine body and a reciprocating feeding mechanism. The lower surface of the machine body is provided with support seats, and the upper surface of the machine body is provided with a feeding port. At both ends of the inner bottom surface of the machine body, there are discharge ports, and a sealing block is connected to the discharge ports through a slide rail assembly. Two baffles are symmetrically arranged inside the machine body, and two mutually meshing crushing rollers are arranged between the baffles. The two shaft ends of the crushing rollers respectively penetrate through both sides of the machine body through bearings, and the rear ends of the two crushing rollers are connected through a gear transmission group.

[0005] Preferably, the structural shape of the discharge port matches the structural shape of the sealing block. The inner bottom surface of the machine body is inclined in an eight-shaped manner, and the upper surface of the sealing block is on the same plane as the inner bottom surface of the machine body.

[0006] Preferably, the reciprocating feeding mechanism includes a driving shaft and a baffle. Two supporting rods are symmetrically installed on the inner side surface of the machine body, and a lead screw is fixedly connected to each supporting rod. Screws are also distributed inside the machine body.

The limit rods are equiangularly distributed at one end of the driving shaft, and the other end of the driving shaft penetrates through the side surface of the machine body through a bearing. The other end of the driving shaft is connected to the corresponding shaft end of the crushing roller through a second belt transmission group. Above each baffle, there is a baffle connected to the inner side of the machine body, and the baffle movably penetrates through the corresponding chain.

[0007] Preferably, two C-shaped channels are formed inside the machine body by two baffles, and the chain penetrates through the C-shaped channel.

[0008] Preferably, the threads on the lead screw and the screw are both reciprocating threads. The thread rotation directions of the two threaded pipes opposite to each other at the same position are opposite, so that when the threaded pipes rotate in one direction, they can reciprocate on the lead screw or the screw, and the moving directions of all the threaded pipes in the same group can be kept consistent.

[0009] Preferably, the support rod is of a T-shaped structure, which is convenient for supporting it inside the machine body without affecting the installation of the chain and the support plate.

In addition, during discharging, the crushed waste can be discharged from the machine body more thoroughly: 1. Through the reciprocating feeding mechanism, the waste after primary crushing can be continuously transported to the position of the feeding port, which helps the crushing roller to crush again, facilitating more thorough crushing of the waste and being beneficial for its recycling and reuse; 2. During discharging, only need to pull the blocking block outwards to make the discharging port communicate with both sides inside and outside the machine body. At this time, through the reciprocating feeding mechanism, the support plate can continuously scrape the waste on the inner bottom surface of the machine body to the discharging port, thus facilitating more thorough discharging; 3. Through the threaded connection between the threaded pipe and the lead screw and between the threaded pipe and the screw rod, when the threaded pipe rotates, it can move along the lead screw or the screw rod, and then drive the support plate to move. Through the reciprocating movement of the support plate, it is not only beneficial to transport the waste on the inner bottom surface of the machine body above the crushing roller, but also can avoid setting a wider support plate, resulting in a large occupation of the internal space of the machine body.

[0017] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0018] Please refer to Figures 1-9 , the present invention provides the following technical solutions: Embodiment 1: To solve the problem that the waste recycling machine for PVC film calendering treatment in the past cannot completely discharge the crushed waste from the recycling machine, the following technical solutions are provided. Specifically, A waste recycling machine for PVC film calendering treatment includes a body 1 and a reciprocating feeding mechanism. A support base 2 is installed on the lower surface of the body 1, and a feed inlet 3 is provided on the upper surface of the body 1. Discharge ports are arranged at both ends of the inner bottom surface of the body 1, and a plugging block 5 is connected to the discharge ports through a slide rail assembly 4. Two baffles 13 are symmetrically arranged in the body 1, and two mutually meshing crushing rollers 9 are arranged between the baffles 13. The two shaft ends of the crushing roller 9 respectively penetrate through both sides of the body 1 through bearings, and the rear ends of the two crushing rollers 9 are connected through a gear transmission group 12. The front end of one of the two crushing rollers 9 is connected to a servo motor 7 through a first belt transmission group 8, and the servo motor 7 is installed on a motor frame 6, and the motor frame 6 is connected to the lower surface of the body 1.

[0019] The structural shape of the blanking port matches the structural shape of the plugging block 5. The inner bottom surface of the machine body 1 is inclined in a V shape, and the upper surface of the plugging block 5 is on the same plane as the inner bottom surface of the machine body 1. The lower part of the support seat 2 is in an H shape to avoid affecting the discharge of the crushed waste. Magnetic sheets are provided at the positions corresponding to the end of the plugging block 5 facing the machine body 1 and the machine body 1. The surfaces of the magnetic sheets on the plugging block 5 and the machine body 1 that face each other are opposite magnetic poles. During use, the plugging block 5 is pulled outwards to make the blanking port at the lower end of the machine body 1 penetrate both the inside and outside of the machine body 1. Thereafter, through the operation of the reciprocating feeding mechanism, the crushed waste on the inner bottom surface of the machine body 1 can be scraped towards the blanking port, so as to discharge the crushed waste from the machine body 1 more thoroughly.

[0020] Embodiment 2: To solve the problem that the waste recycling machine for PVC film calendering treatment in the past needed to manually pour the incompletely crushed waste back above the crushing mechanism, the following technical solution is provided. Specifically, a reciprocating feeding mechanism is installed inside the machine body 1, and the reciprocating feeding mechanism is connected to the shaft end of the corresponding crushing roller 9 through the belt transmission group II 11.

[0021] The reciprocating feeding mechanism includes a drive shaft 10 and a baffle 23. Two support rods 16 are symmetrically installed on the inner side surface of the machine body 1, and a lead screw 17 is fixedly connected to each support rod 16. A screw rod 22 is also distributed inside the machine body 1. Threaded pipes 18 are threadedly connected to the outer side of the screw rod 22 and both ends of the lead screw 17. There are 2 groups of threaded pipes 18, and the 2 groups of threaded pipes 18 are symmetrically arranged with respect to the axial plane of the machine body 1. Each group of threaded pipes 18 is arranged in 2 rows, and the 2 groups of threaded pipes 18 are symmetrically arranged with respect to another axial plane of the machine body 1. A sprocket 19 is key-connected to the outer side of the threaded pipe 18, and all the sprockets 19 in the same row are connected by a chain 14. Pallets 15 are evenly distributed between the chains 14 of the same group. Limit pipes 20 are equally angularly distributed at the outer ends of the threaded pipes 18 connected to both ends of the lead screw 17, and corresponding limit rods 21 are movably inserted into the limit pipes 20. The limit rods 21 are equally angularly distributed at one end of the drive shaft 10, and the other end of the drive shaft 10 passes through the side surface of the machine body 1 through a bearing. The other end of the drive shaft 10 is connected to the shaft end of the corresponding crushing roller 9 through a belt drive group two 11. Above each baffle 13, a baffle 23 connected to the inside of the machine body 1 is provided, and the baffle 23 movably penetrates through the corresponding chain 14. During use, the servo motor 7 drives the crushing roller 9 to rotate.

Through the chain 14, all the sprockets 19 can be synchronously rotated, and then all the threaded pipes 18 are driven to rotate. When the threaded pipe 18 rotates, because it is threadedly connected to the screw rod 22 and the lead screw 17, the threaded pipe 18 and the sprocket 19 and the chain 14 thereon can reciprocally move inside the machine body 1 synchronously, and then the baffle 13 can shovel up the waste materials at different positions on the inner bottom surface of the machine body 1, which helps the incompletely crushed waste materials to pass through the crushing again, and is beneficial to the recycling and reuse of waste materials.

[0022] Two C-shaped channels are formed inside the machine body 1 by two baffles 13, and the chain 14 penetrates through the C-shaped channels. The threads on the lead screw 17 and the screw rod 22 are both reciprocating threads. The thread rotation directions of the two threaded pipes 18 opposite to each other at the same position are opposite, so that when the threaded pipe 18 rotates unidirectionally, it can reciprocally move on the lead screw 17 or the screw rod 22, and the moving directions of all the threaded pipes 18 in the same group can be kept consistent. The support rod 16 is of a T-shaped structure, which is convenient to support it inside the machine body 1 and does not affect the installation of the chain 14 and the pallet 15. The distance between the two chains 14 in the same group is not greater than 1 / 3 of the front-back distance inside the machine body 1, which is convenient for the structure formed by the two chains 14 to have a larger moving range inside the machine body 1. The structural shape of the pallet 15 is T-shaped, and the pallet 15 is made of an elastic material, which is convenient to shovel up the incompletely crushed waste materials.
