Description

Technical Field

[0001] This utility model relates to the field of extruder technology, specifically to a PS recycled plastic wire extruder. Background Technology

[0002] Recycled PS plastic refers to polystyrene-based plastics, which are currently widely used. Plastic production requires plastic extruders, which are production equipment that plasticizes raw materials and shapes them through a die. Types include twin-screw extruders, single-screw extruders, multi-screw extruders, and screwless extruders. During operation, the plastic material enters one end of the extruder from the feed hopper. The screw drives the material forward, and during this process, the material is heated and softened. Under the shearing and compression action of the screw, the material melts into a viscous flow state and is finally extruded through the die at the other end of the extruder. However, some residue remains in the device after molding, requiring cleaning to prevent affecting subsequent use.

[0003] A search of Chinese patent CN216100300U reveals a cleaning device for an ABS engineering plastic extruder. The device includes an arc-shaped groove above a placement platform, a fixed frame mounted above the platform, and the platform and frame fixedly connected by bolts. A fastening screw is mounted on one side of the fixed frame, and the fixed frame is threadedly connected to the fastening screw. A sliding ring is provided on the outer side of the cleaning cylinder, and a rotating ring is provided on the outer side of the sliding ring. A pressure box is located above the rotating ring, and the rotating ring is inserted into the pressure box.

[0004] The aforementioned patent utilizes a fastening screw to ensure stability during the cleaning process. The cleaning process consists of a rotating ring and a scraper, which can effectively scrape off the residue on the inner wall of the extrusion cylinder. However, it cannot remove the residue between the gaps in the device, resulting in some of the scraped residue remaining in the extrusion cylinder. This leads to an unsatisfactory cleaning effect and affects the subsequent use of the plastic extruder. Utility Model Content

[0029] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0030] Example 1:

[0031] Reference Figure 1-4 A PS recycled plastic wire extruder includes a base plate 1, with an extruder body 2 mounted on top of the base plate 1. The extruder body 2 includes a drive motor 201 and two housings 202. The output shaft of the drive motor 201 is fixedly connected to a spiral discharge roller 203 via a coupling. The spiral discharge roller 203 is located between the two housings 202. An adjustment assembly 3 is provided in the inner cavity of the base plate 1. The adjustment assembly 3 includes a dual-shaft motor 301 fixedly installed in the inner cavity of the base plate 1. The output shafts on both sides of the dual-shaft motor 301 are fixedly connected to a first threaded rod 302 via a coupling. A first threaded sleeve 303 is threadedly connected to the surface of the first threaded rod 302. The top of the first threaded sleeve 303 is fixedly... A fixing plate 304 is connected, and the opposite sides of the two fixing plates 304 are respectively fixedly connected to two outer shells 202. The inner walls of the two outer shells 202 are provided with heating blocks 204. By setting up the drive motor 201, the outer shells 202, the spiral discharge roller 203 and the heating blocks 204, a plastic extruder is constructed, which can process plastic. After processing, the two outer shells 202 can be quickly disassembled and separated by adjusting the setting of component 3, exposing the spiral discharge roller 203. At this time, it is convenient for the user to clean the molten plastic material adhering to the inner walls of the two outer shells 202 and the surface of the spiral discharge roller 203, thus improving the cleaning effect.

[0032] Example 2:

[0033] Reference Figure 2 , Figure 3 and Figure 4A lifting assembly 4 is provided on the top left side of the base plate 1. The lifting assembly 4 includes a lifting box 401 fixedly connected to the top left side of the base plate 1. A lifting motor 402 is fixedly connected to the bottom of the inner cavity of the lifting box 401. The output shaft of the lifting motor 402 is fixedly connected to a second threaded rod 403 via a coupling. A second threaded sleeve 404 is threadedly connected to the surface of the second threaded rod 403. A hopper 13 is fixedly connected to the right side of the second threaded sleeve 404 via a connector, which allows for height adjustment of the hopper 13 to facilitate feeding the extruder. On opposite sides of the two outer shells 202, there are respectively a mounting groove 5 and a mounting block 6 for mutual cooperation. The mounting block 6 is located in the inner cavity of the mounting groove 5, which can increase the sealing when the two outer shells 202 are assembled together. First sliding grooves 7 are provided on both sides of the bottom of the inner cavity of the base plate 1. A first slider 8 is slidably connected to the inner cavity of the first sliding groove 7. The top of the first slider 8 is fixedly connected to the first threaded sleeve 303, which allows for movement of the first threaded sleeve 303. The limiting and guiding movement increases the stability when the first threaded rod 302 drives the first threaded sleeve 303 to move. A second slide groove 9 is provided on the left side of the inner cavity of the lifting box 401. A second slider 10 is slidably connected to the inner cavity of the second slide groove 9. The right side of the second slider 10 is fixedly connected to the first threaded sleeve 303, which can limit and guide the movement of the second threaded sleeve 404, increasing the stability when the second threaded rod 403 drives the second threaded sleeve 404 to move. A support block 11 is fixedly connected to the bottom of the drive motor 201. The bottom of the support block 11 is fixedly connected to the bottom plate 1, which can support and fix the bottom of the drive motor 201. Thus, after the two outer shells 202 are disassembled, the drive motor 201 and the spiral discharge roller 203 can be supported, increasing the stability during cleaning. A feed arc hole 12 is provided on the left side of the top of the opposite side of the two outer shells 202. The discharge valve at the bottom of the hopper 13 is located in the inner cavity of the two feed arc holes 12, which can facilitate the addition of raw materials into the extruder for processing.

[0034] The working principle is as follows:

[0035] When in use, the raw material is poured into the hopper 13, and then the raw material in the hopper 13 can be added into the extruder body 2 by controlling the discharge valve. This allows for the processing of plastics, including conveying, compacting, melting, etc., and finally shaping the plastics.

[0036] After processing is completed, the lifting motor 402 is started to drive the second threaded rod 403 to move upward. The second threaded rod 403 drives the second threaded sleeve 404 to move upward, which in turn drives the hopper 13 to move upward, so that the discharge valve at the bottom of the hopper 13 moves out from the inner cavity of the two inlet arc holes 12. Then, the dual-axis motor 301 is started to drive the two first threaded rods 302 to rotate. Due to the design of the positive and negative threads on the surface of the two first threaded rods 302, the two first threaded sleeves 303 can be driven to move in opposite directions at the same time. The two first threaded sleeves 303 can drive the fixing plate 304 to move in opposite directions, which can then drive the two outer shells 202 to be disassembled and separated, exposing the spiral discharge roller 203. At this time, it is convenient for the user to clean the molten plastic material adhering to the inner wall of the two outer shells 202 and the surface of the spiral discharge roller 203, thus improving the cleaning effect.

[0037] After cleaning is completed, start the dual-axis motor 301 to drive the two first threaded rods 302 to rotate in opposite directions, which will drive the two outer shells 202 to close together, so that the mounting block 6 enters the mounting groove 5, which can increase the sealing of the two outer shells 202 and facilitate the next plastic processing operation.

[0038] In summary, this PS recycled plastic wire extruder, by setting up a drive motor 201, a housing 202, a spiral discharge roller 203, and a heating block 204, together constitutes a plastic extruder capable of processing plastics. After processing is completed, the two housings 202 can be quickly disassembled and separated by adjusting the settings of component 3, exposing the spiral discharge roller 203. This allows the user to easily clean the molten plastic material adhering to the inner walls of the two housings 202 and the surface of the spiral discharge roller 203, improving the cleaning effect.
