Description

Technical Field

[0001] The utility model relates to the technical field of PVC rubber material processing, in particular to a crushing device used for PVC rubber material processing. Background Art

[0002] PVC, or polyvinyl chloride, is a polymer formed by the free radical polymerization of vinyl chloride monomer in the presence of initiators such as peroxides and azo compounds, or under the influence of light or heat. During the PVC processing process, crushing equipment is often required to break up and cut large pieces of PVC to facilitate subsequent processing and handling of fine particles. Due to the high viscosity of PVC, blade crushers are commonly used for crushing.

[0003] When using a blade crusher, after starting the motor, the shaft with the blade rotates, and after feeding the material into the crusher, the blade is used to cut it. However, in existing blade crushers, only the blade inside the machine is used for cutting, and there is no pre-cutting structure at the feeding port. It takes a long time to cut the PVC rubber material into the required particle size, and the cutting efficiency is average. In addition, a screen is provided in the crusher to screen the particles that meet the size after cutting. However, the screen is installed with screws, and installation and removal require the operation of multiple screws, which is time-consuming and labor-intensive. In some crushers, the screen is installed by plugging, which has poor stability after installation, thus affecting the use effect. Utility Model Content

The rotating plate 501 and the front end plate 502 are fixedly connected by the connecting rod 504. The connecting shaft 503 is connected to the rotating plate 501 and the front end plate 502, and the end of the connecting shaft 503 is connected to the bearing seat 3. The crushing knife 505 is installed on the connecting rod 504, the feed port 506 is opened on the front end plate 502, and the pre-cutter 507 is fixed in the feed port 506 on the front end plate 502. Through the setting of the cutting structure 5, the pre-cutter 507 and the feed port 506 are provided on the front end plate 502, which can be pre-cut during the feeding process, and then used in conjunction with the crushing knife 505 on the connecting rod 504 to crush the pre-cut materials, thereby increasing the crushing effect and shortening the crushing time.

[0021] When the equipment is used to crush PVC rubber, the equipment is stably placed by the bracket 9. After starting the motor 11 on the support plate 10, the motor 11 drives the cutting structure 5 at the bearing seat 3 to rotate through the pulley and the belt. The connecting shaft 503 rotates with the rotating plate 501 and the front end plate 502. The entire cutting structure 5 rotates and the material is fed through the feed hopper 8 on the flip cover 2. The PVC rubber first contacts the pre-cutter 507 at the front end plate 502. Under the action of the pre-cutter 507, the PVC rubber is initially crushed and fed through the feed port 506. The initially crushed PVC rubber material after feeding is further crushed under the action of the crushing knife 505 on the connecting rod 504. After crushing, the fine particles pass through the screening structure 6 and fall to the bottom of the crushing box 1, and are finally discharged through the discharge hopper 7, while the larger materials continue to be crushed until they meet the requirements for discharge. In this way, the crushing of the PVC rubber material is achieved, which is convenient for the rapid subsequent processing. When necessary, the equipment can be stopped, the locking screw can be opened, and the flip cover 2 can be opened to inspect the cutting structure 5 inside the equipment. The structure is simple and the operation is convenient.

[0022] According to the above embodiment, the screening structure 6 includes a screen 601, a through hole 602, a circular hole 603, a bottom plate 604, a stud 605, a nut 606, a fastening plate 607, a guide inclined plate 608, an assembly groove 609, an elastic frame 610, an assembly block 611, a cylinder 612 and a spring 613. The through hole 602 is provided on the screen 601, the circular hole 603 is provided on the horizontal plate at the end of the screen 601, the bottom plate 604 is fixedly connected to the stud 605, and the stud 605 passes through the circular hole 603, the nut 606 is connected to the stud 605, the fastening plate 607 is fixedly connected to the guide inclined plate 608, the assembly groove 609 is provided on the bottom plate 604 and the fastening plate 607, the elastic frame 610 is connected between the bottom plate 604 and the fastening plate 607 through the assembly block 611, and the cylinder 612 is fixed to the elastic frame 6 10, the spring 613 is sleeved on the cylinder 612, and the screening structure 6 is adopted. The bottom plate 604, the tightening plate 607, the guide inclined plate 608, the elastic frame 610 and the spring 613 are arranged at the end of the screen 601, so that the entire screening structure 6 is installed in a snap-on manner, and the installation and disassembly are convenient and quick. After the screen 601 is installed, the tightening plate 607, the elastic frame 610 and the spring 613 can ensure the stability after installation and the use effect. The elastic frame 610 is installed between the tightening plate 607 and the bottom plate 604 through the assembly block 611, which can be quickly installed and disassembled, and is convenient for quick replacement.

It has high stability after installation and can also be disassembled for corresponding operations, with high flexibility in use.

[0023] Before installing the screening structure 6, the elastic frame 610 is set between the holding plate 607 and the bottom plate 604 using the assembly groove 609 and the assembly block 611, and then the bottom plate 604 is set on the horizontal plate at the end of the screen 601. The stud 605 passes through the circular hole 603, and the nut 606 is installed on the stud 605 to fix it, thereby completing the assembly of the entire screening structure 6. When installing the screening structure 6, the screen 601 is stuck into the arc-shaped slot on the inner wall of the crushing box 1. In this process, the guide inclined plate 608 plays a guiding role, so that the holding plate 607 moves toward the bottom plate 604 and compresses the elastic frame 610 and the spring 613 on the cylinder 612. When the screen After the installation of 601 is completed, the clamping plate 607 contacts the fixed plate 4. Under the joint action of the elastic frame 610 and the spring 613, the clamping plate 607 is in close contact with the fixed plate 4, thereby ensuring the installation stability of the screen 601. During use, the through holes 602 on the screen 601 are used to screen the material. The material smaller than the through hole 602 passes through the screen 601 and is discharged from the lower hopper 7. The material larger than the through hole 602 continues to stay on the screen 601. The cutting structure 5 can be used to continue cutting until the material is smaller than the through hole 602 for falling. When necessary, the screening structure 6 can be quickly disassembled for cleaning and other operations. The structure is simple and the operation is flexible and convenient.
