[0042] Reference Figure 1-11 A thermoplastic elastomer raw material processing device includes a support structure 14, and a crushing tank 1 is provided in the support structure 14. The bottom of the crushing tank 1 is connected to a discharge pipe 101, and a feeding control valve is provided in the discharge pipe 101 for controlling the feeding of the crushing tank 1. The top of the crushing tank 1 is connected to a tank cover 102 by bolts. A feeding hopper 103 is connected to the surface of the crushing tank 1 near the top. The crushing tank 1 is provided with a crushing component, and a washing and drying component is provided on the crushing component. A screening structure is connected in the support structure 14 and is located below the discharge pipe 101. The crushing component drives the screening structure to work through a linkage component 13.

[0043] The crushing assembly includes a servo motor 2, and the output end of the servo motor 2 is connected to a rotating drum 3. The rotating drum 3 is connected to a turning screw 4 and a crushing rod. When the servo motor 2 rotates, it can drive the rotating drum 3 to rotate. The rotating drum 3 drives the turning screw 4 and the crushing rod to rotate, which is used to turn the material in the crushing tank 1 and crush it into particles.

[0044] The rinsing and drying assembly includes through holes A301 and B501, a protective shell 7, and a tee fitting. By connecting the external hot air dryer and water pump to the rotating drum 3, during rinsing, the water pump injects water into the rotating drum 3 through the tee fitting and through hole A301, and then the water enters the crushing rod from the rotating drum 3 and is sprayed out from through hole B501. The material is rinsed while the crushing assembly rotates counterclockwise to turn it over. After rinsing, the hot air dryer blows hot air into the rotating drum 3 through the tee fitting and through hole A301, and then into the crushing rod. Finally, hot air is sprayed out from through hole B501, and the material is dried with hot air while the crushing assembly rotates counterclockwise to turn it over.

[0045] When crushing is required, the servo motor 2 drives the drum 3 to rotate clockwise, and the drum 3 drives the turning screw 4 and the crushing rod to rotate clockwise. The turning screw 4 turns the material over, and the crushing rod crushes the material into granules.

[0046] The screening structure includes a screening box 161 and an end cover 162. The screening box 161 is connected to a discharge hopper 163, and a screening component 164 is provided in the screening box 161.

[0047] Reference Figure 1-11The servo motor 2 is mounted on the top center of the can cover 102 via a motor bracket. The end of the rotating drum 3 away from the servo motor 2 passes through the can cover 102 and extends into the crushing can 1. The material turning screw 4 connected to the surface of the rotating drum 3 is located in the crushing can 1. When the servo motor 2 starts and drives the rotating drum 3 to rotate, the rotating drum 3 drives the material turning screw 4 to rotate and turn the material in the crushing can 1. The crushing rods include multiple stirring rod cylinders 5 connected to the rotating drum 3 by threaded connection, and the surface of the stirring rod cylinder 5 is connected to the crushing blade 6 by bolts. When the rotating drum 3 drives the stirring rod cylinder 5 to rotate, the stirring rod cylinder 5 crushes the material in the crushing can 1 through the crushing blade 6.

[0048] Reference Figure 1-11 The support structure 14 includes an inner frame 141 connected to the crushing tank 1, and an outer frame 142 connected to the outside of the inner frame 141. A support block 15 is connected to the outer frame 142 through a folded support block. A placement opening 151 is provided at the middle of the top of the support block 15. Two placement slots 152 are provided on the top of the support block 15. The two placement slots 152 are connected to the outer ring of the support block and are symmetrical with respect to the placement opening 151. Two sets of fixing blocks 153 are fixedly connected to the top of the support block 15 and are located on both sides of the placement opening 151.

[0049] Reference Figure 1-11 The screening box 161 is inserted into the placement port 151, and one side of the screening box 161 is connected to the end cover 162 by bolts. The screening box 161 is located between two sets of fixing blocks 153 and is locked by bolts. The top of the screening box 161 is connected to the feed pipe 1611 that is sleeved outside the discharge pipe 101, and the outer ring of the screening box 161 has a discharge port 1612. The discharge hopper 163 is connected to the discharge port 1612 on the surface of the screening box 161, and the bottom of the screening box 161 has a screening hole 1613.

[0050] Reference Figure 1-11 The linkage assembly 13 includes a shaft 131 connected to the upper side of the outer frame 142 via a positioning block 133. A pulley B132 and a bevel gear A134 are respectively connected to the top and bottom of the surface of the shaft 131. The linkage assembly 13 also includes a pulley A12 connected to the surface of the rotating drum 3. The pulley A12 is connected to the pulley B132 via a transmission belt. In this way, the rotating drum 3 drives the pulley B132 to rotate, the pulley B132 drives the pulley A12 to rotate via the transmission belt, the pulley A12 drives the shaft 131 to rotate, and the shaft 131 drives the bevel gear A134 to rotate.

[0051] The screening component 164 includes a rotating rod 1641 that rotatably passes through the screening box 161 and the end cover 162, and the two ends of the rotating rod 1641 extend to the outside of the screening box 161 and the end cover 162, respectively. One end of the rotating rod 1641 is connected to a bevel gear A134 that meshes with the bevel gear B1642 and is located outside the screening box 161. A tilting screening component 1643 is connected to the surface of the rotating rod 1641 and is located in the screening box 161. The tilting screening component 1643 includes a sleeve, and multiple screening plates are arranged circumferentially on the surface of the sleeve 1643.

[0052] During operation, shaft 131 drives rotating rod 1641 to rotate via bevel gear A134 meshing with bevel gear B1642. Rotating rod 1641 drives tilting screen 1643 to rotate within screening box 161. When material needs to be discharged, servo motor 2 rotates counterclockwise, driving drum 3 to rotate, which in turn drives shaft 131 to rotate. Shaft 131 then drives rotating rod 1641 to rotate, which in turn drives screening plate to rotate counterclockwise. This opens the discharge control valve in discharge pipe 101 at the bottom of crushing tank 1, allowing the washed and crushed particles in crushing tank 1 to fall into adjacent screening box 161. Between the two screening plates, a perforation is provided on the surface of the screening plate. The crushed material in the granules falls through the perforation on the screening plate to the bottom of the screening box 161 and falls through the screening hole 1613. As the rotating rod 1641 drives the screening plate to rotate in the screening box 161, the two adjacent screening plates drive the crushed granules to move counterclockwise in the screening box 161. When the granules between the two adjacent screening plates pass through the screening hole 1613, the crushed material in the granules is screened out. The crushed granules remaining in the screening box 161 are driven by the screening plates to reach the discharge port 1612 and slide out from the discharge hopper 163.

[0053] Reference Figure 1-11 Through hole A301 is opened on the surface of the rotating drum 3, and through hole B501 is opened on the surface of the stirring rod cylinder 5. The protective shell 7 is connected to the surface of the stirring rod cylinder 5 by bolts and covers the through hole B501. Through hole B501 allows water and hot air to flow out. Through hole C701 is opened on the surface of the protective shell 7, which also allows water and hot air to flow out. The protective shell 7 and through hole C701 can prevent granules and debris from entering the stirring rod cylinder 5 through through hole B501.

[0054] Reference Figure 1-11The tee includes a sleeve 8 and a tee pipe 9. One end of the tee pipe 9 is connected to the sleeve 8 by a threaded connection. One-way valves 10 are provided on the surface of the tee pipe 9 near both ends. The one-way valves 10 only allow water or hot air to enter the tee pipe 9 and will not return. The sleeve 8 is sleeved on the surface of the rotating drum 3 through a sealed bearing and covers the outside of the through hole A301. An annular cavity is formed between the inner wall of the sleeve 8 and the outer wall of the rotating drum 3 and is connected to the tee pipe 9. The two ends of the tee pipe 9 are respectively connected to the external hot air dryer equipment and the water supply pump.

[0055] When it is necessary to clean the material in the crushing tank 1, the water supply pump supplies water to the three-way pipe 9. The water source enters the annular cavity and enters the rotating drum 3 through the through hole A301. After the water fills the rotating drum 3, it enters the stirring rod cylinder 5 and is sprayed out from the through hole B501. It also reaches the crushing tank 1 through the through hole C701, and is cleaned while stirring and turning the material.

[0056] When drying is required, the water supply pump is turned off, the hot air dryer is started and hot air is blown into the three-way pipe 9. The hot air enters the annular cavity and enters the rotating drum 3 through the through hole A301. After the hot air fills the rotating drum 3, it enters the stirring rod cylinder 5 and is sprayed out through the through hole B501. It then reaches the crushing tank 1 through the through hole C701, and dries the material while stirring and turning it.

[0057] Reference Figure 1-11 The three-way pipe 9 penetrates the crushing tank 1 and is secured and positioned by fasteners 11. The fasteners 11 include a connecting ring 111 connected to the surface of the crushing tank 1. Multiple clamping plates 112 are connected to the surface of the connecting ring 111. The multiple clamping plates 112 are arranged in a circle. The outer surfaces of the multiple clamping plates 112 are fitted with clamping screw rings 113 by threaded connection. In the initial state, the clamping screw rings 113 are attached to the surface of the connecting ring 111, and the multiple clamping plates 112 are separated from the connecting ring 111. The inner surfaces of the multiple clamping plates 112 are provided with anti-slip layer. In use, the three-way pipe 9 penetrates the crushing tank 1 and the connecting ring 111 and is located between the multiple clamping plates 112. Then, the clamping screw rings 113 are rotated away from the connecting ring 111, and the multiple clamping plates 112 are brought closer together and clamped to the surface of the three-way pipe 9 by the anti-slip layer, thereby locking and fixing the three-way pipe 9 penetrating the crushing tank 1.

[0058] Reference Figure 1-11 The inner frame 141 includes a connecting ring connected to the surface of the crushing tank 1, and a plug block is fixedly connected to the surface of the connecting ring. The number of plug blocks is at least three. The outer frame 142 includes a support block that is fitted around the plug block. A support rod is fixedly connected to the bottom of the support block. The support blocks are connected to each other by a reinforcing rod, so that the outer frame 142 and the inner frame 141 cooperate to support the crushing tank 1.
