Description

Technical Field

[0001] The present invention relates to the technical field of PVC recycling, and specifically to a granulating mechanism for PVC recycled materials used in the processing of environmentally friendly mixed glue. Background Technique

[0002] In order to avoid waste of PVC resources, the most common way to recycle and reuse PVC waste is to make it into environmentally friendly mixed glue for reuse. During the manufacturing process of the mixed glue, PVC recycled materials need to be added to a crushing box to be cut into granular form. The granular recycled materials are discharged through a discharge port. A screen is provided in the discharge port, and the screen can screen out the particles that meet the production requirements for discharging. In the actual production process, there are two reasons for frequently replacing the screen. On the one hand, different sizes of recycled material particles are usually required according to different production demands. In this case, different screens need to be replaced according to the requirements to collect the recycled material particles that meet the demands. On the other hand, after the screen is used for a certain period of time, recycled material particles will get stuck in its screen holes, resulting in blockage of the screen. It needs to be disassembled and cleaned. However, the screen is installed inside the discharge port, and the discharge port is at the lower end of the entire device. Due to the limitation of the internal space of the discharge port and the position of the discharge port, the installation and disassembly of the screen are very inconvenient, which in turn affects the working efficiency of screen replacement. In addition, after the blocked screen is disassembled, it also requires special cleaning by staff, which is rather troublesome and increases the working intensity of the staff.

[0015] Compared with the prior art, the invention has the following advantages:

[0016] 1. A load-bearing positioning plate is installed at the lower end of the load-bearing frame. When installing the screening carrier plate, simply place it on the load-bearing positioning plate, and then pull the driving operation plate to quickly push the screening carrier plate into the discharge hole, achieving automatic locking installation of the screening carrier plate, which is very convenient.

Moreover, the environmentally friendly mixed glue made from recycled PVC materials can be used for anti-collision sheets of products such as gloves, knee pads, and elbow pads.

[0017] 2. When the load-bearing positioning plate drives the screening carrier plate to move into the discharge hole, with the cooperation of the movable plate, the fixation between the screening carrier plate and the load-bearing positioning plate can be achieved, thereby ensuring the stability of the screening carrier plate during movement. At the same time, it will also drive the screening carrier frame to move upward relative to the screening carrier plate, so that the screening plugging strip is inserted into the screening channel, making the first screening slot and the second screening slot form a complete screening hole for facilitating the screening of particles.

[0018] 3. In addition, when it is necessary to disassemble the screening carrier plate, pull out the plugging positioning block from the positioning lower jack, and under the action of the first return spring and the self-gravity of the screening carrier plate, it will withdraw from the discharge port and at the same time achieve unlocking of the screening carrier plate, facilitating its quick removal. And the screening carrier frame moves downward relative to the screening carrier plate under the action of the second return spring and its own gravity. In this way, the first screening slot and the second screening slot can be separated and misaligned, so that particles cannot get stuck in the screening hole, and they can be directly poured out or they can automatically fall, which is very convenient and greatly reduces the cleaning work intensity of the staff.

[0040] A plug-in positioning rod 8 is inserted into the installation movable hole 14. A matching end plate 81 is fixedly arranged at the upper end of the plug-in positioning rod 8, and a plug-in positioning block 82 is fixedly arranged at the lower end. When the plug-in positioning block 82 is not inserted into the positioning lower jack 21, it is in contact with the upper end surface of the driving operation plate 2. In addition, when the plug-in positioning block 82 fixes the driving operation plate 2, it is inserted into the positioning lower jack 21.

[0041] The PVC recycled material is added from the feeding tray 162 into the crushing box body 16 for crushing. In the crushing box body 16, sharp-edged cutting tools are used to ensure the crushing efficiency. The crushed particles come out from the discharge port 161 through the sieve carrier plate 5 and the sieve bearing frame 6. Particles with a volume of 1 - 125 mm³ can be made according to needs. Moreover, the environmentally friendly mixed glue made from the PVC recycled material can be used on the anti-collision pieces of products such as gloves, knee pads, and elbow pads. When installing the sieve carrier plate 5, it is placed on the bearing positioning plate 3, that is, the positioning through hole 56 is sleeved on the positioning connecting block 33 to achieve the positioning of the sieve carrier plate 5. Then, the driving operation plate 2 is pulled. Under the action of the connecting driving link 26, the bearing positioning plate 3 is pushed upward. Furthermore, under the action of the bearing positioning plate 3, the sieve carrier plate 5 is driven to move upward and inserted into the discharge port 161 to achieve automatic locking installation. During the upward movement of the bearing positioning plate 3, under the action of the driving connection slideway 181, the matching movable plate 4 is driven to move toward the positioning connecting block 33. In this way, the plugging fixing rod 43 is inserted into the inner plugging connection hole 57 and contacts the plugging guiding rod 71. The insertion of the plugging fixing rod 43 into the inner plugging connection hole 57 realizes the fixed connection between the sieve carrier plate 5 and the bearing positioning plate 3, thus ensuring the stability of the sieve carrier plate 5 during movement. In addition, as the plugging fixing rod 43 moves, it will push the plugging guiding rod 71 to move. In this way, the connecting movable plate 7 is driven to move away from the positioning matching connecting plate 55. In this way, under the action of the first connecting carrier rod 72, the connecting plate frame 73 is pulled to move toward the positioning matching connecting plate 55. As the connecting plate frame 73 moves, under the action of the second connecting carrier rod 76, the sieve bearing frame 6 is pushed to move upward relative to the sieve carrier plate 5, so that the sieve plugging strip 62 is inserted into the sieve channel 52 until the upper end surface of the sieve plugging strip 62 is flush with the upper end surface of the sieve carrier plate 5. At this time, the first sieve slot 53 and the second sieve slot 63 are aligned and closed together to form a sieve hole, which can screen the particles. At the same time, the positioning lower insertion hole 21 is aligned with the plugging positioning rod 8. Under the action of gravity, the plugging positioning rod 8 moves downward, and the plugging positioning block 82 is inserted into the positioning lower insertion hole 21 to realize the fixation of the driving operation plate 2, thus completing the installation of the sieve carrier plate 5. When it is necessary to replace the sieve carrier plate 5 or clean the sieve hole, the plugging positioning rod 8 is pulled upward so that the plugging positioning block 82 exits the positioning lower insertion hole 21. Then, under the action of the first return spring 25 and the self-gravity of the sieve carrier plate 5, the sieve carrier plate 5 moves downward and exits the discharge port 161. Moreover, at the same time, the automatic unlocking of the sieve carrier plate 5 can be realized, and it can be quickly removed. In addition, during the downward movement of the sieve carrier plate 5, under the action of the second return spring 74 and the self-gravity of the sieve bearing frame 6, the sieve bearing frame 6 moves downward relative to the sieve carrier plate 5 to reset. In this way, the first sieve slot 53 and the second sieve slot 63 can be separated and misaligned, so that the particles stuck in the sieve hole either fall directly,Either in the screening channel 52, where rapid removal of particles can be carried out, which is very convenient.
