Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of modified plastic particle production, in particular to a special waste plastic regenerative modified plastic particle production device for drainage board. BACKGROUND

[0002] The special regenerative modified plastic particle for drainage board is a special material made of recycled plastic as raw material after modification and enhancement, which has excellent anti-aging property, durability and drainage performance, and is the core raw material for producing environmentally friendly drainage board.

[0003] In the production process of the special regenerative modified plastic particle for drainage board, the processing quality and efficiency of the plastic raw material have a crucial influence on the performance and production cost of the final product. At present, although some plastic particle production devices exist in the market, there are still many problems to be solved in actual production and application. On the one hand, most of the existing production devices lack effective pretreatment links, and the plastic raw material often directly enters the subsequent processing process without being fully crushed and finely screened, which not only leads to uneven size of the raw material particles, affecting the uniformity and stability of plastic processing, and further reducing the quality of the special regenerative modified plastic particle for drainage board, but also may cause energy waste and low production efficiency due to the difficulty of fully melting and mixing of large pieces of raw material. On the other hand, in the raw material conveying aspect, most devices adopt continuous conveying mode, which is difficult to accurately control the conveying amount, and may cause the pretreatment mechanism to be inconvenient due to excessive load, and even cause equipment failure, affecting the continuity and stability of production. In addition, in the pretreatment process, due to the lack of effective auxiliary means, the plastic raw material is easy to accumulate and adhere in the pretreatment mechanism, which affects the crushing and screening effect, and further affects the quality and efficiency of subsequent plastic processing.

This not only enhances the uniformity and modification efficiency of subsequent melt blending, but also effectively ensures the stability and reliability of the final recycled granules in key indicators such as mechanical strength and weather resistance, laying a solid material foundation for the production of high-performance drainage boards.

[0021] In the above scheme, a vibration mechanism is installed. When the pretreatment mechanism is started, the two will be closely linked, synchronously activating the vibration mechanism to rhythmically vibrate the pretreatment components. In the crushing stage of plastic raw materials, vibration can effectively break the adhesion between raw material particles, making the raw materials looser and more uniform as they enter the crushing area, thereby greatly improving crushing efficiency and making the crushed particles more uniform in size. During the screening process, continuous vibration can promote the rapid flow of raw materials on the screen, effectively preventing fine particles from clogging the screen holes, greatly improving the accuracy and throughput of screening, and laying a solid foundation for subsequent high-quality production.

[0022] In the above solution, a conveying mechanism is installed to intermittently and evenly transport plastic raw materials to the pretreatment mechanism, avoiding problems such as equipment jamming and malfunction caused by raw material accumulation. This greatly reduces the frequency of equipment failures and effectively extends the service life of the equipment. At the same time, the uniform material conveying allows the pretreatment mechanism to fully exert its processing efficiency, and can fully and meticulously process each batch of raw materials, thereby ensuring the stable and reliable quality of the pretreated raw materials and laying a solid foundation for subsequent high-quality production.

[0046] Please see Figures 1-4 One end of the conveying pipe 202 is open, and an inlet 203 is provided on the conveying pipe 202 for feeding plastic raw materials into the conveying pipe 202. The conveying pipe 202 is inclined at a 45-degree angle to the horizontal plane, and the outlet end of the conveying pipe 202 is directly above the crushing box 301. The other end of the conveying pipe 202 is rotatably connected to a shaft 205. The shaft 205 is cylindrical and is used to support the installation of the first gear 210. One end of the shaft 205 passes through the conveying pipe 202 and is fixedly connected to one end of the screw rod 204.

The first gear 210 is fixedly mounted with limit blocks 206 to facilitate meshing with the teeth 208. The limit blocks 206 are used to support the sliding of the turntable 209. There are four limit blocks 206, which are symmetrically distributed in a ring around the shaft 205. The other end of the conveying pipe 202 is fixedly mounted with a first motor 207 to drive the turntable 209 to rotate. The turntable 209 is fixedly mounted on the shaft end of the first motor 207. The turntable 209 is used to support the installation of the teeth 208. The turntable 209 is circular in shape, and the teeth 208 are fixedly mounted on the turntable 209 to mesh with the first gear 210.

[0047] Please see Figure 1 , Figure 2 , Figure 5 , Figure 6 , Figure 7 and Figure 8The frame 304 is square in shape and horizontally positioned. It serves to receive the screen frame 303. A baffle 307 is fixedly installed on the inner wall of the crushing box 301.

The baffle 307 has a triangular cross-section, and there are two baffles 307 horizontally positioned. A second motor 310 is fixedly installed on the surface of the crushing box 301. The second motor 310 drives the first roller to rotate and is horizontally positioned. The crushing roller 309 includes a first roller and a second roller. The shaft of the second motor 310 passes through the inner wall of the crushing box 301 and is fixedly connected to the first roller. One end of the first roller and the second roller both pass through the crushing box 301 and are respectively fixedly installed with a second gear 308. There are two second gears 308. When the first roller rotates, it will synchronously drive the second roller to rotate. The rotation directions of the first roller and the second roller are opposite, so as to crush the plastic raw material. The two second gears 308 mesh with each other. One end of the second gear 308 is fixedly installed with a rotating rod 305. The rotating rod 305 is cylindrical and is used to support the installation of the protrusion 306. The rotating rod 305 is horizontal and the protrusion 306 is fixedly installed on the rotating rod 305. The cross-sectional shape of the protrusion 306 is right-angled triangle. The protrusion 306 is used to lift the circular roller 409 away from the surface of the rotating rod 305.

[0048] Please see Figure 1 , Figure 2 , Figure 9 and Figure 10 A connecting plate 408 is fixedly installed on the receiving plate 402. The connecting plate 408 is square in shape and is used to support the installation of the bracket 407. The connecting plate 408 is horizontally positioned, and a bracket 407 is fixedly installed at one end of the connecting plate 408. The bracket 407 is arched in shape and is used to support the installation of the circular roller 409.

A support rod 4 is fixedly installed at the bottom end of the receiving plate 402. 03. The support rod 403 is set to support the installation of the second striking block 405. The support rod 403 is L-shaped, and the second striking block 405 is fixedly installed at one end of the support rod 403. The second striking block 405 is set to strike the frame 304, thereby achieving the purpose of the vibrating screening frame 303, which is conducive to the screening of plastic raw materials. A spring 412 is fixedly installed on the inner wall of the box 401. One end of the spring 412 is fixedly connected to the limiting plate 411. The spring 412 is set to apply force to the roller 409 so that the roller 409 is in close contact with the surface of the rotating rod 305.

[0049] Working principle: During use, plastic raw materials are fed into the feed inlet 203. The plastic raw materials will enter the conveying pipe 202 through the feed inlet 203, and at the same time, the first motor 207 is started. When the first motor 207 is working, it will drive the turntable 209 to rotate. The initial state of the turntable 209 when rotating is shown in the attached figure. Figure 4 As shown, the turntable 209 slides on the inner wall of one of the limiting blocks 206. During its rotation, the turntable 209 drives the teeth 208 to rotate. When the teeth 208 mesh with the first gear 210, the turntable 209 has left the inner wall of the limiting block 206. The turntable 209 then drives the first gear 210 to rotate via the teeth 208 until the teeth 208 leave the surface of the first gear 210. At this point, the turntable 209 moves back into one of the limiting blocks 206, thus achieving rotation of the first gear 210. The motion limit function ensures that the tooth 208 meshes with the first gear 210 again. Through the above settings, the first gear 210 will rotate intermittently under the drive of the tooth 208 and the turntable 209. During the intermittent rotation of the first gear 210, the shaft 205 will rotate intermittently. During the intermittent rotation of the shaft 205, the screw rod 204 will rotate intermittently. The screw rod 204 will intermittently and evenly convey the plastic raw material into the crushing box 301, avoiding the situation of conveying too much at one time.

[0050] During the conveying of plastic raw materials, the second motor 310 is started. Since the crushing roller 309 includes a first roller and a second roller, the second motor 310 will drive the first roller to rotate. When the first roller rotates, it will drive the second roller to rotate through the second gear 308. The rotation direction of the second roller is opposite to that of the first roller. The plastic raw material will fall into the crushing box 301 through the conveying pipe 202 and slide between the first roller and the second roller through the baffles 307 on both sides, which is conducive to the crushing roller 309 crushing the plastic raw material. The crushed plastic raw material will fall into the screening frame 303 through the crushing box 301 and be filtered through the screening frame 303. The filtered plastic raw material will enter the plastic production component 5 through the frame 304 for processing.

[0051] Furthermore, during the crushing process of the plastic raw material, the second gear 308 will synchronously drive the rotating rod 305 to rotate. When the rotating rod 305 rotates, it will drive the protrusion 306 to rotate. Due to the setting of the spring 412, the roller 409 is tightly attached to the surface of the rotating rod 305. When the protrusion 306 moves to the roller 409, it will drive the roller 409 to leave the surface of the rotating rod 305. During the process of the roller 409 leaving the rotating rod 305, it will drive the limiting plate 411 to squeeze the spring 412 through the bracket 407, connecting plate 408, receiving plate 402 and connecting rod 410. When the protrusion 306 leaves the roller 409, the roller 409 will be under the spring 412. Under the action of 2, it once again presses against the surface of the rotating rod 305 until the protrusion 306 rotates to the roller 409 again. Through the above settings, the roller 409 will drive the receiving plate 402 to move back and forth through the bracket 407 and the connecting plate 408. During the back and forth movement, the receiving plate 402 will drive the first striking block 406 to strike the crushing box 301 through the striking rod, which is conducive to crushing the plastic raw materials and avoiding the occurrence of blockage. At the same time, the receiving plate 402 will also drive the second striking block 405 to strike the frame 304 through the support rod 403, thereby providing vibration force for the screening frame 303 so as to screen the crushed plastic raw materials.
