The arrangement of the reinforcing ribs 10 effectively ensures the structural strength of the cooling cavity 18 and the cooling cavity 29, while reducing the resistance to the water flow, making the water flow smoother.

[0029] Specifically, two baffle plates 101 are symmetrically arranged inside the body 1, and the baffle plates 101 are arranged at an angle. The two baffle plates 101 are respectively located above the two rolling rollers 6. The setting of the baffle plates 101 is used to prevent the engineering plastics from flowing to the two sides of the two rolling rollers 6, so that the engineering plastics are concentrated between the two rolling rollers 6 for rolling. The rolling blocks 64 of the two rolling rollers 6 bite each other to roll the engineering plastics once. The engineering plastics after rolling may be in sheet form. After passing through the high-speed rotating crushing roller 7, the crushing effect of the engineering plastics is guaranteed.

A bottom cover 103 is hinged at the bottom of the crushing barrel 102, and one end of the bottom cover 103 away from the hinge is closed by adsorption with the crushing barrel 102 through an electromagnet, and it is more convenient to open the bottom cover 103 through the control of the electromagnet.

Later, the water inlet tank 4 and the drainage tank 5 can be connected through a pipeline on the rear side of the machine body 1 to form a communicating vessel principle, which can be recycled and more energy-saving.

[0032] Specifically, a surface fixed sleeve of the rotating shaft 61 is provided with a rolling gear 62, and the rolling gears 62 at both ends of the two rolling rollers 6 are meshed with each other. One of the surface fixed sleeves of the rotating shaft 61 is provided with a small gear 63. The two rolling rollers 6 roll the engineering plastics through relative rotation of the rolling gear 62, and perform preliminary rolling on the difficult-to-crush and large-piece engineering plastics, which greatly reduces the crushing difficulty of the crushing roller 7.

[0033] Specifically, one side of the driving box 3 is provided with a motor 1 31 and a motor 2 32, the output end of the motor 1 31 is provided with a driving gear 1 33 meshing with one of the crushing gears 62, the output end of the motor 2 32 is provided with a driving gear 2 34 transmission-connected with one of the rotating shafts 2 71, the motor 1 31 adopts a low-speed and high-torque reduction motor to ensure the crushing effect, the motor 2 32 adopts a high-speed servo motor to accurately control the rotation speed, the rotating shaft 2 71 is provided with a gear meshing with the driving gear 2 34 and the gear diameter is smaller than the driving gear 2 34, so that the driving gear 2 34 rotates one circle, which can drive the rotating shaft 2 71 and the crushing roller 7 to rotate multiple circles.

[0034] Specifically, guide plates 104 are hinged on both sides of the inner wall of the body 1, and the two guide plates 104 are respectively located above the two baffle plates 101, and rubber plates 105 and springs 106 are provided between the guide plates 104 and the baffle plates 101. The guide plates 104 support the engineering plastics inside the storage enclosure 2 through the resilience of the springs 106, and at the same time, when the engineering plastics are driven by the unloading rollers 13 to descend, they will perform a small reverse motion to adapt, so that large pieces of engineering plastics fall without getting stuck, and the rubber plates 105 can shield the engineering plastics to prevent the engineering plastics from getting stuck between the guide plates 104 and the baffle plates 101, and at the same time will not affect the flipping motion of the guide plates 104.

[0035] Specifically, a feeding roller 13 located between two guide plates 104 is rotatably arranged inside the machine body 1, and a circle of the feeding roller 13 is provided with a plurality of shifting blocks 131, and the engineering plastics to be crushed are poured into the interior of the storage enclosure 2, and the motor 31 is started to drive the rolling roller 6 to rotate, and the rolling roller 6 drives the feeding roller 13 to rotate, and the feeding roller 13 drives the shifting blocks 131 to shift the engineering plastics, thereby avoiding the situation that the engineering plastics are stuck and cannot fall, and automatic feeding is realized without manual intervention.

[0036] Specifically, one end of the unloading roller 13 extends to the interior of one of the driving boxes 3 and is provided with a large gear 132, and the large gear 132 is connected to the small gear 63 through a toothed belt transmission, see Figure 3 The pinion 63 and the large gear 132 are connected by a toothed belt transmission. The rolling roller 6 has to rotate multiple times to drive the unloading roller 13 to rotate one circle, thereby avoiding the situation where the unloading speed is too fast and affects the rolling efficiency.

[0037] In summary, the crushing equipment for engineering plastics can transport water for cooling to the rotating rolling roller 6 and crushing roller 7 through the water inlet pipe 11, which can effectively avoid the situation where the engineering plastics melt and adhere to the rolling roller 6 and the crushing roller 7 due to high temperature, thereby ensuring the crushing efficiency. The crushed engineering plastics can be crushed repeatedly inside the crushing barrel 102, further ensuring the crushing efficiency. The discharge is controlled by the discharge roller 13 and the guide plate 104, which effectively avoids the situation where the discharge is stuck.
