[0002] Thermoplastic elastomer is also called artificial rubber or synthetic rubber. When processing it, a pelletizer is needed. The pelletizer is used to cut long strips of thermoplastic elastomer into small particles of thermoplastic elastomer of equal volume.

[0003] The Chinese utility model patent with the authorization announcement number CN217494834U discloses a TPE thermoplastic elastomer material pelletizer, including a base, a pelletizer assembly and a limit assembly. A pelletizer box is installed on the upper surface of the base. The pelletizer assembly includes a cylinder, a piston rod, a positioning telescopic rod, a blade and a fixed plate. The limit assembly is mainly composed of a pelletizer plate, a pelletizer groove and a fixed block. The two sides of the pelletizer plate are respectively provided with a feed port and a discharge port. Its working principle is: after the strip-shaped thermoplastic material enters the pelletizer plate, the piston rod on the cylinder will push the fixed plate downward, so that multiple sets of blades are embedded in multiple sets of pelletizer grooves, and the strip-shaped thermoplastic material is cut into granules. Through the cooperation between the blades with the same spacing and the pelletizer groove, the size of each thermoplastic elastomer is kept consistent to prevent the elastomer from sticking to the pelletizer mechanism.

[0004] However, the above technical solution has the following problems: when the blade cuts the thermoplastic elastomer, due to the strong viscosity of the thermoplastic elastomer, molten material often adheres to the blade, causing the blade to stick, affecting the subsequent cutting effect of the thermoplastic elastomer.

[0034] The above technical solution can be used to clean the blade 4. When the blade 4 cuts the thermoplastic elastomer, the surface will be attached with molten material. When the blade 4 reaches the lowest point, it touches the switch. The switch activates the second electric push rod 11 to push the movable plate 12 out of the through groove 26, so that the brush 13 on the surface of the movable plate 12 is close to the blade 4. When the first electric push rod 3 drives the blade 4 to rise, the blade 4 and the brush 13 rub against each other, and when the movable plate 12 moves, it will drive the piston plate 18 to move through the extension rod 19, and the piston plate 18 will drain the water in the piston box 17 through the drain pipe. 21 squeezes into the nozzle 22, the nozzle 22 sprays water onto the blade 4, and cooperates with the brush 13 to wash the blade 4 with water, so as to clean the molten material on the surface of the blade 4. When the blade 4 completely leaves the gap between the shells 8, the switch controls the second electric push rod 11 to drive the movable plate 12 and the brush 13 to retract into the through groove 26, and in the process of the movable plate 12 retracting, the piston plate 18 will be driven to move through the extension rod 19, and negative pressure will be created in the piston box 17, so that the water in the water storage chamber 14 is pumped into the piston box 17 through the suction pipe 20 for use in the next round of cutting.

[0035] Further, such as Figure 1 and Figure 2 As shown, a slide plate 5 is provided at the bottom of the housing 8, and the slide plate 5 is slidably matched with a slide rail 6 opened in the through opening 2.

When the shell 8 needs to be taken out of the pelletizing box 1 for maintenance, the locking knob 7 is rotated to release the limit on the slide 5, and the slide 5 is pushed out of the opening 2 of the pelletizing box 1 along the slide rail 6. The shell 8 can be taken out together with the slide 5, which is very convenient.

[0037] Further, such as Figure 2 and Figure 3 As shown, the slide plate 5 is provided with a groove 23 below the gap between the two shells 8, and the groove 23 is provided with a drainage groove 24, which is connected to the bottom groove 25 provided in the pelletizing box 1;

After the water storage chamber 14 is filled, the cover plate 16 is closed.

[0041] Working principle: When in use, first feed the thermoplastic elastomer from the material port 9, and drive the front end of the thermoplastic elastomer to move to the bottom of the blade 4 through the feeding mechanism of the pelletizer. The first electric push rod 3 pushes the blade 4 downward, and the blade 4 cuts the thermoplastic elastomer. When the blade 4 cuts the thermoplastic elastomer, the molten material will adhere to the surface. When the blade 4 reaches the lowest point, it touches the switch. The switch activates the second electric push rod 11 to push the movable plate 12 out of the through slot 26, so that the brush 13 on the surface of the movable plate 12 is close to the blade 4. When the first electric push rod 3 drives the blade 4 to rise, the blade 4 and the brush 13 rub against each other, and the movable plate 12 moves while passing The extension rod 19 drives the piston plate 18 to move, and the piston plate 18 squeezes the water in the piston box 17 into the nozzle 22 through the drain pipe 21. The nozzle 22 sprays water onto the blade 4, and cooperates with the brush 13 to wash the blade 4 with water, so as to clean the molten material on the surface of the blade 4. When the blade 4 completely leaves the gap between the shells 8, the switch controls the second electric push rod 11 to drive the movable plate 12 and the brush 13 to retract into the through groove 26, and in the process of retracting the movable plate 12, the piston plate 18 will be driven to move through the extension rod 19 to create negative pressure in the piston box 17, so that the water in the water storage chamber 14 is pumped into the piston box 17 through the suction pipe 20 for use in the next round of cutting.
