A worktable is provided on the upper outer surface of the base. A double-roller crushing device for improving the crushing efficiency of plastic particles is provided on the upper outer surface of the worktable. A feed inlet is provided on the upper outer surface of the double-roller crushing device, a discharge plate is provided on one side of the outer surface of the double-roller crushing device, and a baffle plate is fixedly installed on one side of the outer surface of the double-roller crushing device. A screening and recycling device for improving the detection of plastic particle crushing effect is provided below the discharge plate. The modified plastic particle crushing and mixing device of this utility model, by incorporating a double-roller crushing device, allows plastic raw materials to be fed into the crushing chamber through the feed inlet. The two sets of rotating crushing rollers can crush the raw materials. The structure is simple, not only improving the crushing efficiency of plastic particles and increasing work efficiency, but also ensuring thorough crushing of the plastic raw materials and improving product quality.

[0004] In existing crushing and mixing devices, screening plates are required to screen the crushed plastic particles during the processing. Over time, dust and impurities from the crushing process tend to accumulate on the screening plates, causing the screen holes to become clogged, which in turn reduces screening efficiency and affects processing efficiency.

Therefore, this invention proposes a modified plastic granule raw material crushing and stirring device.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a modified plastic granule raw material crushing and mixing device, comprising a crushing component and a mixing component, wherein the crushing component is provided with an air jet component, the mixing component is provided with a mixing component, the crushing component includes a crushing box, and crushing rollers are symmetrically installed inside the crushing box, the mixing component includes a mixing tank and a mixing motor, a drive shaft is installed inside the mixing tank, and multiple mixing rollers are distributed on the outer side of the drive shaft, a screening plate is provided inside the crushing box, and the air jet component includes an air pump and an air storage tank, a conveying pipe is connected to the side of the air storage tank, an air jet frame is installed at one end of the conveying pipe, and multiple high-pressure nozzles are distributed on the air jet frame.

[0012] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0013] 1. In this utility model, the operation of the air pump is beneficial to filling the air tank with high-pressure gas. The high-pressure gas is transported to the inside of the air jet frame through the delivery pipe and sprayed out through multiple high-pressure nozzles. This is beneficial to achieve reverse air blowing cleaning of the screening plate, which helps to blow away the impurities and dust accumulated on the screening plate, reducing the clogging of the screening plate, reducing the manual cleaning cost, and thus improving the cleaning efficiency.

It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0022] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0023] Example 1: As Figures 1-5As shown, this utility model provides a technical solution: a modified plastic granule raw material crushing and mixing device, including a crushing component 1 and a mixing component 2. The crushing component 1 is equipped with an air jet component 3, and the mixing component 2 has a mixing component 4 inside. The crushing component 1 includes a crushing chamber 101, with crushing rollers 102 symmetrically installed inside the crushing chamber 101. The mixing component 2 includes a mixing tank 201 and a mixing motor 202. A drive shaft 204 is installed inside the mixing tank 201, and multiple mixing rollers 205 are distributed on the outer side of the drive shaft 204. The crushing box 101 is equipped with a screening plate 105. The jet assembly 3 includes an air pump 301 and an air tank 302. A conveying pipe 303 is connected to the side of the air tank 302. An air jet frame 304 is installed at one end of the conveying pipe 303. Multiple high-pressure nozzles are distributed on the air jet frame 304. A gear disk 103 is connected to one end of the crushing roller 102. A servo motor 104 is installed at one end of one of the gear disks 103. A slide rail 106 is symmetrically installed at one end of the crushing box 101. A sealing plate 107 is movably installed inside the slide rail 106.

[0024] In this embodiment, a servo motor 104 electrically drives one of the gear disks 103 to rotate. The gear disk 103 meshes with the other gear disk 103, which facilitates the rotation of the two crushing rollers 102, thereby crushing the plastic particles. The screening plate 105 facilitates the screening of the crushed plastic particles. Qualified plastic particles enter the interior of the mixing tank 201 through the connecting pipe 108. The movable sealing plate 107 moves inside the slide rail 106, which facilitates the feeding of larger plastic particles. The air pump 301 operates to facilitate the feeding of the storage tank. The gas tank 302 is filled with high-pressure gas, which is then transported through the delivery pipe 303 to the inside of the jet frame 304 and sprayed out through multiple high-pressure nozzles. This facilitates reverse air blowing cleaning of the screening plate 105, helps to blow away impurities and dust accumulated on the screening plate 105, reduces clogging of the screening plate 105, and lowers the cost of manual cleaning, thereby improving cleaning efficiency. The stirring motor 202 electrically drives the transmission shaft 204 to rotate, which in turn drives the stirring roller 205 to rotate, thus facilitating the mixing and stirring of plastic particles and additives.

[0025] Example 2: Figures 1-5 As shown, the mixing component 4 includes a scraper frame 401, which is mounted on the drive shaft 204. Multiple scraper blades 402 are distributed on the scraper frame 401. A connecting pipe 108 is connected to the bottom of the crushing box 101. The bottom of the connecting pipe 108 is connected to the top of the mixing tank 201. A discharge pipe 206 is connected to the bottom of the mixing tank 201, and a feed inlet 203 is connected to the top of the mixing tank 201.

[0026] In this embodiment, the scraper frame 401 is set outside the drive shaft 204. The drive shaft 204 facilitates the rotation of the scraper frame 401 and the scraper blade 402. The scraper frame 401 is useful for scraping the inner wall of the mixing tank 201, and the scraper blade 402 is useful for scraping the bottom of the mixing tank 201. This effectively reduces the amount of material adhering to the inner wall of the mixing tank 201, thereby facilitating thorough mixing of the material, improving mixing efficiency, and finally causing the material to be discharged through the discharge pipe 206.

[0027] The working principle of this embodiment is as follows: In use, firstly, the servo motor 104 electrically drives one of the gear disks 103 to rotate. The gear disk 103 meshes with the other gear disk 103, facilitating the rotation of the two crushing rollers 102, thereby crushing the plastic particles. The screening plate 105 facilitates the screening of the crushed plastic particles. Qualified plastic particles enter the mixing tank 201 through the connecting pipe 108. The movable sealing plate 107 moves within the slide rail 106, facilitating the discharge of larger plastic particles. Then, the stirring motor 202 electrically drives the transmission shaft 204 to rotate, which in turn drives the stirring roller 205 to rotate, thus facilitating the mixing of the plastic particles and additives. The transmission shaft 204 has… The scraper frame 401 and scraper blade 402 are driven to rotate. The scraper frame 401 is useful for scraping the inner wall of the mixing tank 201, and the scraper blade 402 is useful for scraping the bottom of the mixing tank 201. This effectively reduces the amount of material adhering to the inner wall of the mixing tank 201, which in turn facilitates the thorough mixing of the material. Finally, the material is discharged through the discharge pipe 206. After processing, the air pump 301 is used to fill the air tank 302 with high-pressure gas. The high-pressure gas is transported to the air jet frame 304 through the conveying pipe 303 and sprayed out through multiple high-pressure nozzles. This is beneficial for reverse air blowing cleaning of the screening plate 105, which helps to blow away the impurities and dust accumulated on the screening plate 105 and reduces the clogging of the screening plate 105.
