Description

Technical Field

[0001] This utility model relates to the field of extruder technology, specifically to a plastic pultrusion equipment with waste recycling function. Background Technology

[0002] Plastic pultrusion equipment, also known as an extruder, is a type of plastic machinery. Extruders can be classified into right-angle extruders and angled extruders based on the angle between the material flow direction at the die head and the screw centerline. Screw extruders rely on the pressure and shearing force generated by the rotation of the screw to fully plasticize and uniformly mix the material, which is then formed through a die.

[0003] As shown in the reference case "An extruder with waste recycling function" (publication number CN217670932U), the residual material on the inner wall of the extruder can be scraped off, and then the scraped material can be recycled through the recycling structure, so that the device has the function of waste recycling, thereby avoiding waste of resources.

[0004] Existing extruders typically require multiple disassembly steps and rely on additional drive components to complete the cleaning process when recycling waste material from the inner wall of the extrusion tube. This cumbersome operation not only increases the workload of recycling and maintenance but also seriously affects the ease of use and production efficiency of the equipment.

[0005] Based on this, this utility model designs a plastic pultrusion equipment with waste recycling function to solve the above problems. Utility Model Content

[0006] In view of the above-mentioned shortcomings of the existing technology, the present invention provides a plastic pultrusion equipment with waste recycling function.

[0007] To achieve the above objectives, this utility model provides the following technical solution:

[0008] A plastic pultrusion device with waste recycling function includes a plastic extruder, an extrusion head fixedly installed on one side of the plastic extruder, and a control seat fixedly installed on the surface of the plastic extruder; a waste recycling mechanism, which is disposed on one side of the plastic extruder for convenient recycling of waste inside the plastic extruder; wherein, the waste recycling mechanism includes an extrusion tube fixedly installed inside the plastic extruder, an auger rod rotatably installed inside the extrusion tube, a recycling component disposed on one side of the plastic extruder, and a limit component disposed on one side of the recycling component.

[0009] Furthermore, the recycling assembly includes a placement frame fixedly installed on one side of a plastic extruder. A cover plate is provided on the surface of the plastic extruder, one side of which extends to one side of the extrusion tube. The placement frame is fixedly installed on one side of the plastic extruder. A recycling ring is provided inside the placement frame. A guide groove is formed on the surface of the recycling ring. The shape of the guide groove is adapted to the blades of the auger rod.

[0010] Furthermore, the diameter of the recycling ring is the same as that inside the extrusion tube, and a scraper ring is fixedly installed on the surface of the recycling ring.

[0011] Furthermore, the scraper ring has two storage grooves on its surface, with the two storage grooves located on both sides of the scraper ring.

[0012] Furthermore, the limiting component includes movable grooves formed on the surfaces of the plastic extruder and the extrusion tube, and the cover plate is slidably connected to two of the movable grooves simultaneously.

[0013] Furthermore, a movable block is fixedly installed on the surface of the scraper ring, and the movable block is used in conjunction with the movable groove.

[0014] Furthermore, a guide frame is fixedly installed on the surface of the plastic extruder, the guide frame is located on one side of the cover plate, and a limiting plate is slidably installed on the surface of the guide frame, the limiting plate being located on one side of the cover plate.

[0015] Furthermore, the surface of the limiting plate has two friction grooves, which are equidistantly distributed. Beneficial effects

[0016] 1. When waste needs to be recycled, the extruder head can be removed, and the waste inside the extrusion tube can be easily cleaned and recycled through the recycling component, improving recycling efficiency and reducing operation difficulty. The limit component can ensure the normal use of the plastic extruder and extrusion tube when the recycling component is not in use.

[0017] 2. When the cover plate is not disassembled, the cover plate can be limited by sliding the limiting plate to the top of the cover plate, thereby ensuring that the cover plate is stably fixed when the plastic extruder is used. When moving the limiting plate, the friction force can be increased by the two friction grooves, thereby ensuring stable movement. Attached Figure Description

Detailed Implementation

[0025] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0026] The present invention will be further described below with reference to the embodiments.

[0027] In some embodiments, please refer to the appendix to the instruction manual. Figure 1-4 A plastic pultrusion device with waste recycling function includes a plastic extruder 1, an extrusion head 11 fixedly installed on one side of the plastic extruder 1, and a control seat 2 fixedly installed on the surface of the plastic extruder 1; a waste recycling mechanism 3, which is provided on one side of the plastic extruder 1 for convenient recycling of waste inside the plastic extruder 1; wherein, the waste recycling mechanism 3 includes an extrusion tube 31 fixedly installed inside the plastic extruder 1, an auger rod 12 rotatably installed inside the extrusion tube 31, a recycling component 32 provided on one side of the plastic extruder 1, and a limit component 33 provided on one side of the recycling component 32.

[0028] In one embodiment of this utility model, when it is necessary to recycle waste, the extruder head 11 can be removed, and the waste on the inner wall of the extrusion tube 31 can be cleaned and recycled conveniently through the recycling component 32, thereby improving recycling efficiency and reducing operational difficulty. The limiting component 33 can ensure the normal use of the plastic extruder 1 and the extrusion tube 31 when the recycling component 32 is not in use.

[0029] The plastic extruder 1 is mainly composed of basic components such as barrel, auger rod 12, heating device, cooling system, control seat 2, extrusion tube 31 and extrusion head 11. The recycling component 32 and the limiting component 33 enable convenient recycling of waste materials without changing the core structure and function of the plastic extruder 1, ensuring that the plastic extruder 1 maintains efficient and stable operation under normal production conditions.

[0030] In some embodiments, such as Figure 2 and Figure 3 As shown, the recycling assembly 32 includes a placement frame 21 fixedly installed on one side of the plastic extruder 1. A cover plate 321 is provided on the surface of the plastic extruder 1. One side of the cover plate 321 extends to one side of the extrusion tube 31. The placement frame 21 is fixedly installed on one side of the plastic extruder 1. A recycling ring 322 is provided inside the placement frame 21. A guide groove 323 is provided on the surface of the recycling ring 322. The shape of the guide groove 323 is adapted to the blades of the auger rod 12.

[0031] In one embodiment of this utility model, the recycling ring 322 slides in contact with the guide groove 323 that matches the blade of the auger rod 12. When the auger rod 12 rotates normally, it can passively drive the recycling ring 322 to slide along the inner axial direction of the extrusion tube 31. No additional power system is required. The rotational motion of the existing auger rod 12 can be used to synchronously drive the recycling ring 322 to scrape and clean the inner wall of the extrusion tube 31, thereby improving the convenience of waste recycling.

[0032] The diameter of the recovery ring 322 is the same as that of the inside of the extrusion tube 31, and a scraper ring 325 is fixedly installed on the surface of the recovery ring 322.

[0033] In one embodiment of this utility model, when the recycling ring 322 moves, the scraper ring 325 closely adheres to the inner wall surface of the extrusion tube 31. As the recycling ring 322 slides axially, it scrapes off the waste material remaining on the inner wall of the extrusion tube 31.

[0034] Two storage slots 326 are formed on the surface of the scraper ring 325, and the two storage slots 326 are located on both sides of the scraper ring 325 respectively.

[0035] In one embodiment of this utility model, when the scraper ring 325 is recycling waste, the two storage slots 326 are used to temporarily collect and store the waste scraped off from the inner wall of the extrusion tube 31. When the recycling ring 322 moves the scraper ring 325 along with the rotation and sliding of the auger rod 12, the scraped waste will first fall into the two storage slots 326 on the surface of the scraper ring 325, thus preventing the waste from scattering during the cleaning process.

[0036] In some embodiments, such as Figure 2 and Figure 4 As shown, the limiting component 33 includes a moving groove 331 formed on the surface of the plastic extruder 1 and the extrusion tube 31, and the cover plate 321 is slidably connected to both moving grooves 331.

[0037] In one embodiment of this utility model, when recycling is required, the cover plate 321 is separated from the moving groove 331, and the recycling ring 322 can be placed in for waste recycling. At the same time, the side of the cover plate 321 located inside the extrusion tube 31 can be easily cleaned.

[0038] A movable block 324 is fixedly installed on the surface of the scraper ring 325, and the movable block 324 is used in conjunction with the movable groove 331.

[0039] In one embodiment of this utility model, when the scraper ring 325 is inserted, the moving block 324 is located in the moving groove 331 to limit and guide the scraper ring 325, so that the scraper ring 325 moves smoothly along the axial direction of the extrusion tube 31 under the drive of the recovery ring 322, ensuring that the scraper ring 325 is in close contact with the inner wall of the extrusion tube 31, thereby improving the stability and accuracy of waste scraping.

[0040] A guide frame 332 is fixedly installed on the surface of the plastic extruder 1. The guide frame 332 is located on one side of the cover plate 321. A limit plate 333 is slidably installed on the surface of the guide frame 332. The limit plate 333 is located on one side of the cover plate 321.

[0041] In one embodiment of this utility model, when the cover plate 321 is not disassembled, the cover plate 321 can be limited by sliding the limiting plate 333 to the top of the cover plate 321, thereby ensuring that the cover plate 321 is stably fixed when the plastic extruder 1 is in use.

[0042] The surface of the limiting plate 333 has two friction grooves 334, which are equidistantly distributed.

[0043] In one embodiment of this utility model, when moving the limiting plate 333, the friction force can be increased by the two friction grooves 334, thereby ensuring stable movement.

[0044] In this embodiment of the invention, the recovery ring 322 slides in contact with the guide groove 323 that matches the blades of the auger rod 12. When the auger rod 12 rotates normally, it passively drives the recovery ring 322 to slide axially along the inside of the extrusion tube 31. No additional power system is required; the rotational motion of the existing auger rod 12 can synchronously drive the recovery ring 322 to scrape and clean the inner wall of the extrusion tube 31, improving the convenience of waste recycling. When the scraper ring 325 is inserted, the moving block 324 is located in the moving groove 331 to limit and guide the scraper ring 325, allowing it to move smoothly along the axial direction of the extrusion tube 31 under the drive of the recovery ring 322. This ensures that the scraper ring 325 is tightly attached to the inner wall of the extrusion tube 31, improving the stability and accuracy of waste scraping. As the recovery ring 322 moves... At the same time, the scraper ring 325 is closely attached to the inner wall surface of the extrusion tube 31. As the recovery ring 322 slides axially, it scrapes off the waste material remaining on the inner wall of the extrusion tube 31. When the scraper ring 325 is recycling waste material, the two storage slots 326 are used to temporarily collect and store the waste material scraped off from the inner wall of the extrusion tube 31. When the recovery ring 322 moves with the rotation and sliding of the auger rod 12, the scraped waste material will first fall into the two storage slots 326 on the surface of the scraper ring 325 to prevent the waste material from scattering during the cleaning process. When recycling is required, the cover plate 321 is separated from the moving slot 331, and the recovery ring 322 can be put in for waste recycling. At the same time, it is also convenient to clean the side of the cover plate 321 located inside the extrusion tube 31.

Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features.
