A chiller is mounted on the vertical plate of the frame. This novel device facilitates adjustment of the cutting blade during operation, ensuring that the blade maintains close contact with the template surface, and its structure extends the service life of the blade.

[0004] When using existing high-efficiency underwater pelletizing devices, rubber and plastic pellets tend to accumulate on the screen plate, causing blockage and affecting the screening efficiency of the screen plate for rubber and plastic pellets. Utility Model Content

[0005] The purpose of this invention is to provide a high-efficiency underwater pelletizing device to solve the problem of easy clogging of the screen plate in an existing high-efficiency underwater pelletizing device.

[0006] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a high-efficiency underwater pelletizing device, including a pelletizing box, a pelletizing knife installed inside the pelletizing box and connected to a drive mechanism that drives its movement, a water spraying assembly installed on the pelletizing box, a cleaning structure provided on one side of the top of the pelletizing box, a feed inlet installed at the top of the pelletizing box, the pelletizing box being fixedly installed on a base, a screening box installed inside the base, the screening box being connected to the pelletizing box through a discharge channel, an anti-clogging structure provided inside the discharge channel, a discharge port installed on one side of the screening box, a screening component installed inside the screening box, and a striking mechanism for driving its movement provided below the screening component, the striking mechanism including a connecting shaft installed below the screening component, a fixed motor connected to the connecting shaft, and striking hammers evenly installed on the connecting shaft.

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] Please see Figures 1-5 The present invention provides a high-efficiency underwater pelletizing device, including a pelletizing box 7.

[0031] Reference Figures 1-5 As shown, a pelletizing blade 10 is installed inside the pelletizing box 7, and the pelletizing blade 10 is connected to the drive mechanism 1 that drives it to move. A water spraying assembly 9 is installed on the pelletizing box 7. The water spraying assembly 9 includes a water pump 901, a water pipe 902 and a water spray nozzle 903. The water pipe 902 is installed between the pelletizing box 7 and the screening box 3. The water pump 901 is installed on the water pipe 902, and a water spray nozzle 903 is installed at one end of the water pipe 902.

[0032] The top of the pelletizing box 7 is equipped with a feed inlet 8, and a cutting mold is installed inside the feed inlet 8. The pelletizing box 7 is fixedly installed on the base 2, and a screening box 3 is installed inside the base 2. The screening box 3 is connected to the pelletizing box 7 through the discharge channel 6.

[0033] A discharge port 5 is installed on one side of the screening box 3. A screening assembly 11 is installed inside the screening box 3. The screening assembly 11 is used to screen rubber and plastic granules. The screening assembly 11 includes a support 1101, a limiting spring 1102, a connector 1103 and a screen plate 1104. The support 1101 is installed on the inner wall of the screening box 3. The limiting springs 1102 are evenly installed on the support 1101 and the screen plate 1104 is installed on the limiting springs 1102. The screen plate 1104 has an inclined structure. The connector 1103 is installed between the screen plate 1104 and the inner wall of the screening box 3.

[0034] Below the screening component 11 is a striking mechanism 4 for moving it. The striking mechanism 4 includes a connecting shaft 403 installed below the screening component 11, a fixed motor 401 connected to the connecting shaft 403, and striking hammers 402 evenly installed on the connecting shaft 403. The striking hammers 402 are arranged at equal intervals on the connecting shaft 403.

[0035] Rubber and plastic materials enter the pelletizing box 7 through the feed port 8 and the cutting die. The driving mechanism 1 drives the pelletizing knife 10 to move, which cuts the rubber and plastic materials formed by the cutting die into pellets evenly. At the same time, the water pump 901 is started, and the water in the screening box 3 is sent to the spray nozzle 903 through the water pipe 902. The pellets are sprayed out through the spray nozzle 903 to form pellets. The formed rubber and plastic pellets enter the screening box 3 through the discharge channel 6. The screening component 11 screens them. During screening, the fixed motor 401 is started, the connecting shaft 403 rotates, the hammer 402 rotates, and pushes the screen plate 1104 to move upward. During the movement, the limit spring 1102 drives the screen plate 1104 to move, so that the screen plate 1104 shakes and vibrates to screen the rubber and plastic pellets to avoid the screen plate 1104 from clogging. The screened rubber and plastic pellets are discharged from the discharge port 5.

[0036] Reference Figure 2 and Figure 3 As shown, the discharge channel 6 is equipped with an anti-blocking structure 12. The anti-blocking structure 12 is used to continuously feed the rubber and plastic granules in the discharge channel 6 into the screening box 3 for automatic feeding. The anti-blocking structure 12 includes a belt assembly 1201, a spiral blade 1202, a driven gear 1203, a driving gear 1204, and a rotating shaft 1205. The spiral blade 1202 is installed inside the discharge channel 6. The driven gear 1203 is installed at the top of the spiral blade 1202, and the driving gear 1204 is meshed on one side of the driven gear 1203. The rotating shaft 1205 is coaxially installed on one side of the driving gear 1204. The rotating shaft 1205 is connected to the connecting shaft 403 through the belt assembly 1201.

[0037] When the striking mechanism 4 is in operation, the belt assembly 1201 drives the rotating shaft 1205 to rotate, the driving gear 1204 drives the driven gear 1203 to rotate, and the spiral blade 1202 rotates, continuously feeding the rubber and plastic granules in the discharge channel 6 into the screening box 3 for automatic feeding, thus avoiding the situation where rubber granules block the discharge channel 6.

[0038] Reference Figure 2 and Figure 5 As shown, a cleaning structure 13 is provided on one side of the top of the pelletizing box 7. The cleaning structure 13 is used to clean the rubber and plastic materials adhering to the pelletizing blade 10. The cleaning structure 13 includes a fixing frame 1301, a limiting groove 1302, a telescopic spring 1303 and a scraper 1304. The fixing frame 1301 is installed on one side of the top of the pelletizing box 7. The limiting groove 1302 is symmetrically opened on the inner side of the fixing frame 1301. The telescopic spring 1303 is evenly installed inside the limiting groove 1302, and a scraper 1304 is installed on one end of each telescopic spring 1303.

[0039] During pelletizing, the extension spring 1303 causes the scraper 1304 to move and contact the pelletizing blade 10. As the pelletizing blade 10 moves, the scraper 1304 can scrape off the rubber and plastic material adhering to the pelletizing blade 10, thereby cleaning it and improving pelletizing efficiency.
