[0038] Working principle

[0039] First, the staff clamps the extruded plastic strips to be pelletized between the clamping electric wheels 81 in the four clamping channels 19, and continuously passes cooling water through the cooling channel 10, and then starts the equipment power supply;

[0040] After being powered on, the clamping electric wheel 81 rotates to drive the plastic strip to move and gradually extend out of the clamping channel 19. At this time, the cutter head rotation motor 68 arranged on one side of the clamping block 14 drives the cutter head rotating shaft 65 to rotate. The rotation of the cutter head rotating shaft 65 drives the cutter head rotating block 62 and the cutter head connecting rods 71 arranged in a circumferential array outside the cutter head rotating block 62 to rotate. The rotation of the cutter head connecting rods 71 causes the granulating cutter 18 to cut the extended plastic strip with a fixed length while rotating around the cutter head rotating shaft 65. During the rotation of the cutter head connecting rods 71, due to the action of the four lifting-promoting protrusions 67 fixed on the surface of the rotating shaft motor housing 66, the cutter head connecting rods 71 are regularly lifted. Therefore, when the granulating cutter 18 finishes cutting the approaching plastic strip, the cutter head connecting rods 71 are lifted, causing the granulating cutter 18 to move away from the surface of the clamping block 14, thereby separating the cut plastic particles from the original plastic strip to improve the separation degree and prevent adhesion between the particles. When the separation of the particles is completed, since the end of the cutter head connecting rod 71 is fixedly connected to the cutter head moving slider 63 and a moving slider return spring 64 is arranged on one side of the cutter head moving slider 63, the cutter head connecting rods 71 will return to the original height under the action of the moving slider return spring 64 and reattach to the surface of the clamping block 14 for the next granulation;

[0041] The plastic particles separated from the plastic strip enter the lower water chamber 72 under the drive of the cooling water and are first intercepted by the first water filter net 42 arranged at the upper end of the lower water chamber 72. When enough plastic particles accumulate on the surface area of the first water filter net 42, the water passing ability decreases. Therefore, the particle filter rack 41 is pressed down under the action of the cooling water. At this time, since the left supporting plate 24 and the right supporting plate 47 are respectively arranged on both sides below the particle filter rack 41, the left supporting plate 24 and the right supporting plate 47 are pressed down and moved by the particle filter rack 41, driving the left transmission belt 23 and the right transmission belt 48 on both sides to move;

[0042] The movement of the left conveyor belt 23 causes the left support plate 24 on the side away from the particle filter rack 41 to move upward under the movement of the left conveyor belt 23 and finally replace the position of the original left support plate 24. The movement of the right conveyor belt 48 drives the rotation of the right rotating pulleys 46 at the upper and lower ends. The rotation of the right rotating pulleys 46 drives the rotation of the right rotating shaft 45 fixedly connected thereto. The rotation of the right rotating shaft 45 drives the movement of the upper power belt 44 arranged outside. The movement of the upper power belt 44 causes the replacement belt driving shaft 43 connected thereto to rotate. The rotation of the replacement belt driving shaft 43 drives the movement of the replacement conveyor belt 40 sleeved outside. The movement of the replacement conveyor belt 40 transports the particle filter rack 41 placed on the upper surface of the replacement conveyor belt 40 inward and finally replaces the position of the original particle filter rack 41. At the same time, when the particle filter rack 41 moves to the end of the replacement conveyor belt 40 and enters the water discharge chamber 72, the left support plate 24 and the right support plate 47 that have moved up from below have replaced the positions of the original left support plate 24 and the right support plate 47. Therefore, after the new particle filter rack 41 disengages from the replacement conveyor belt 40, it moves forward and stops moving after hitting the left limit plate 25 on the surface of the left support plate 24. At this time, the lower sides of both sides of the particle filter rack 41 are supported by the left support plate 24 and the right support plate 47 respectively;

[0043] During the downward movement of the original particle filter rack 41, it will contact the trigger slider 50 arranged on one side of the water discharge chamber 72 and press it into the rear chute. At this time, the movement of the trigger slider 50 drives the rear trigger rod 49 to move inward and activates the translation amplification motor 36 on one side of the trigger rod 49 to make it work. Subsequently, the translation amplification motor 36 pulls the lower sliding amplification rod 54 backward. Since the sliding amplification rod 54 is pulled, the water discharge seal plate 75 connected to the sliding amplification rod 54 through the seal plate pull rod 53 also moves backward and opens the channel of the water discharge chamber 72. Subsequently, the particle filter rack 41 is washed into the filter water tank support bracket 33 below by the cooling water. After the particle filter rack 41 leaves the trigger slider 50, the trigger slider 50 resets under the action of the slider return spring 51, and the sliding amplification rod 54 resets under the action of the translation amplification motor 36 to make the water discharge seal plate 75 reset to re-seal the water discharge chamber 72;

[0044] After the original particle filter rack 41 enters the filter water tank support bracket 33, the plastic particles in the particle filter rack 41 start to drain water. The water flowing into the filter water tank 31 is pumped by the filter water tank water pump 76 on one side and flows through the filter water tank water pipe 77 and the connecting water pipe 78. Under the action of the action body water pump 79, it is transported upward through the rising circulation water pipe 13 into the horizontal circulation water pipe 12, enters the upper circulation water pipe 11 through the horizontal circulation water pipe 12 and finally flows back into the cooling channel 10. During this process, the cooling water is cooled down to achieve the purpose of circulating cooling;

[0045] During the water drainage process of the original particle filter rack 41, the new particle filter rack 41 continues the original process. Therefore, the cooling water continuously enters the water drainage circulation water channel 37 on one side through the water drainage cavity 72 and flows back into the cooling channel 10 under the action of the moving body water pump 79. During this process, the water wheel fan blades 27 arranged on the opposite side of the water drainage circulation water channel 37 are continuously washed by the water flow, thus driving the rotation of the water wheel 26. During the rotation of the water wheel 26, the swing rod slider 29 below is regularly squeezed. When the pressure of the water wheel fan blades 27 is lost, the swing rod slider 29 is pushed back to its original position by the swing rod return spring 28 behind. When the swing rod slider 29 reciprocates, it drives the swing rod 58 below to reciprocate. Since the longitudinal swing connecting rod 59 is arranged at the lower end of the swing rod 58 and the longitudinal swing connecting rod 59 is fixedly connected to the filter water tank support bracket 33, the filter water tank support bracket 33 will reciprocate, driving the particle filter rack 41 in the filter water tank support bracket 33 to reciprocate. Therefore, the plastic particles in the particle filter rack 41 move back and forth to achieve a better filtering effect. The staff only needs to take out the particle filter rack 41 in the filter water tank support bracket 33 every once in a while, pour out the internal plastic particles and put them into the filter rack replacement cavity 39.
