Description

Technical Field

[0001] The utility model relates to the technical field of PVC particle processing, in particular to a super-soft PVC particle extrusion device. Background Art

[0002] PVC stands for polyvinyl chloride. PVC granules are a commonly used plastic semi-finished product. They are made by adding other ingredients to PVC to enhance its heat resistance, toughness, and ductility. PVC granules are heated and melted, then extruded and formed using an extruder, and then cut into granules. Traditional PVC granule extruders often use welding to install the cutting structure. In actual work, we found that this installation method is more troublesome for later maintenance because it is inconvenient to disassemble. If the cutter is damaged or stuck with plastic granules, the cutter must be removed separately. During removal, it is also restricted by the outer bracket, requiring multiple angles to remove the cutter, or the drive motor must be disassembled from the bracket. This disassembly process is multi-step, time-consuming, and inefficient. In addition, repeated disassembly and assembly of the motor will affect its service life. If plastic granules stuck to the cutter are cleaned directly on the machine, it will be restricted by the other parts of the machine structure. It may even cause the machine to start abnormally, causing harm to the user and reducing work safety.

Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making any creative efforts shall fall within the scope of protection of the present invention. Example

[0027] A super-soft PVC particle extrusion device includes an extrusion device body 1, a fixing ring 2 is welded to one end of the surface of the extrusion device body 1, and three end blocks 4 are integrally formed on one side of the fixing ring 2. A slot 5 is provided on one side of the end block 4, and a positioning plug 6 is inserted into the inside of the slot 5. A bracket 3 is provided on one side of the extrusion device body 1, and three positioning plugs 6 are fixedly connected to the bracket 3. A bolt column 1 7 is fixedly connected to one side of the positioning plug 6. Six bolt columns 2 9 are fixedly connected to the outside of the fixing ring 2, and a pressing piece 19 is sleeved on the bolt column 2 9 located on both sides of the bolt column 1 7 and the bolt column 1 7. A fastening nut 1 8 and a fastening nut 2 10 located on the outside of the pressing piece 19 are respectively threadedly installed on the bolt column 1 7 and the bolt column 2 9.

[0028] The specific usage process is as follows: When the cutter 18 is damaged or PVC particles are stuck on the cutter 18, in order to ensure the user's work safety and avoid working directly on the machine, the cutter 18 must be disassembled from the machine. When disassembling, the bracket 3 and the stepper motor 11 are removed from the extruder body 1, so that the stepper motor 11 does not need to be disassembled, and the service life of the stepper motor 11 will not be affected. When disassembling, first loosen and remove the fastening nut 2 10 and the fastening nut 1 8. When all the fastening nuts 2 10 and the fastening nuts 1 8 are removed, remove the pressing piece 19. At this time, the positioning plug 6 will not be restricted by the fastening nut 2 10 and the positioning plug 6, because the bolt column 1 7 is fixedly connected to the positioning plug Block 6, therefore, when all the fastening nuts 2 10 and fastening nuts 1 8 are completely removed, and the pressing piece 19 is also removed, the bracket 3 can be removed from the extrusion device body 1, and the positioning plug 6 will also be moved out of the slot 5, wherein the fixing ring 2 is fixed to the surface of the extrusion device body 1, and can also be welded to the surface of the extrusion device body 1 by welding. After removing the bracket 3 and the positioning plug 6 together, the stepper motor 11 can be removed together with the cutter 18 installed on the stepper motor 11. At this time, the side of the bracket 3 originally installed on the extrusion device body 1 is no longer restricted by the extrusion device body 1, so the cutter 18 can be easily and conveniently removed and replaced, and the cutter can also be more easily and conveniently replaced. 18 is cleaned of particles sticking on it, and a new cutter 18 is replaced, or particles sticking on the cutter 18 are cleaned off, then the stepper motor 11 is lifted and the bracket 3 is aligned with the discharge end of the extrusion device body 1, that is, aligned with the fixing ring 2 on the extrusion device body 1, wherein the positioning plug 6 on the bracket 3 is inserted into the inner portion of the end block 4, so that the bracket 3 can be positioned under the action of multiple slots 5 and the end block 4, and the end of the bracket 3 will also contact the outer wall of the fixing ring 2, thereby ensuring that the cutter 18 is installed in the appropriate position, realizing the positioning of the cutter 18, ensuring that the cutter 18 can accurately complete the pelletizing work without causing damage to the extrusion device body 1, and further adjusting the positioning plug 6. The limit makes the bolt column 1 7 and the positioning plug 6 on the same line, and then the pressing piece 19 can be quickly and accurately clamped to the corresponding bolt column 1 7 and the positioning plug 6. After the pressing piece 19 is clamped, the positioning plug 6 can be positioned, and the bracket 3 can also be positioned, which provides convenience for the subsequent installation of the fastening nut 1 8 and the fastening nut 2 10. Then the fastening nut 2 10 is tightened and fixed to the corresponding fastening nut 2 10, and the fastening nut 1 8 is tightened and fixed to the corresponding bolt column 1 7. In this way, the disassembly and assembly of the bracket 3 and the stepping motor 11 is completed, and the maintenance, replacement and cleaning of the cutter 18 are also completed. Therefore, a structural design that can be flexibly and quickly disassembled and assembled is adopted, and the bracket originally welded on the machine is replaced with a movable fixing method for installation.Therefore, when replacing the cutter blade and cleaning sticky materials on the cutter blade, the cutter blade can be flexibly and quickly removed for maintenance and cleaning, shortening the disassembly and assembly time, improving the maintenance and cleaning efficiency, and providing assistance and convenience for the user's maintenance work. During operation, raw materials are fed into the feed hopper 12, and the raw materials enter the extruder body 1 through the feed hopper 12, and then are extruded through the extruder body 1.

[0034] Specifically, the display 14 is set up to display the working status of the machine. The real-time parameters during operation will be displayed on the display 14 for the user to observe, so that the user can respond to emergencies in a timely manner and provide convenience for the user's work. This is the existing technology.

[0035] A material receiving device 15 is fixedly mounted on one side of the support leg 16 , and a conveyor belt 17 located below the extrusion device body 1 and the stepper motor 11 is fixedly mounted on the top of the support leg 16 , and the conveyor belt 17 is adapted to the material receiving device 15 .

[0036] Specifically, with the arrangement of the conveyor belt 17 and the material receiving device 15, the PVC plastic cut into particles will fall onto the conveyor belt 17, and then be transported toward the material receiving device 15, and finally fall into the material receiving device 15 to be collected. It should be noted that, according to actual usage requirements, the bottom end of the material receiving device 15 can also be connected to a suction device, so that the PVC particles can be automatically sucked away, completing the automatic feeding of the downward process, and providing assistance and convenience for the processing of PVC plastics. It should be noted that the upper opening width of the material receiving device 15 is greater than the width of the conveyor belt 17, so that all the materials can be collected to avoid material scattering.
