Therefore, different materials are mixed, stirred and then extruded to form particles for subsequent use. For example, a nylon plastic granulator with the publication number CN220242063U comprises a granulating box, a feeding conveyor belt and a discharging conveyor belt are installed in the granulating box, and a guide roller, a granulating blade, a cooling box, a filter screen cylinder, a cooling air head and vibrating beads are further arranged in the granulating box. The filter screen cylinder is detachably installed in the cooling box, and a plurality of filter screen openings are formed in the filter screen cylinder to facilitate screening of nylon plastic and granulating debris. A plurality of cooling air heads are installed in the filter screen cylinder to cool the nylon plastic after granulation and clean the granulating debris. The vibrating beads are arranged in multiple groups and are rotationally arranged in the filter screen cylinder. A discharge opening is formed in the lower side of the cooling box to discharge the granulating debris. Through the above technical solution, the problem that the debris generated during cutting of the cooled nylon plastic affects the normal granulation efficiency is solved.

However, the above-mentioned granulator still has the following shortcomings in actual use:

[0004] 1. The traditional granulator mostly sprays liquid to the material for cooling, and then cuts, but this cooling method is not thorough enough, and the center position of the material is not formed, which affects the smoothness of the granulation.

[0005] 2. And the liquid that cools the material is in contact with the high-heat material for a long time, which causes the overall temperature of the liquid to rise, and when the liquid needs to be recycled, it will affect the subsequent cooling of the material, so there is a lack of structure to cool the cooling liquid.

[0006] In view of the above problems, it is urgent to make innovative design on the basis of the original water-cooled cutting machine. SUMMARY

[0015] Preferably, the second movable cylinder is rotatably disposed on the top of the cooling box, and the cooling box is fixed to the top of the fixed box, and the edge of the piston plate slides against the inner wall of the cooling box.

[0016] Preferably, a water supply pipe and a water return pipe are respectively provided at the lower ends of both sides of the cooling box, and the cooling box, the water supply pipe, the water return pipe and the fixed box form a liquid circulation channel, and a one-way valve is provided in both the water supply pipe and the water return pipe.

[0017] Preferably, the upper end of the side of the cooling box is fixedly connected to one end of the gas supply pipe, and the other end of the gas supply pipe is fixed to the fixed box.

[0019] A method of using a non-metallic explosion-proof ball water-cooled pelletizer, the method comprising the following steps:

[0020] Step 1: Equipment debugging. Set the preset pressure threshold, preset temperature threshold, heating temperature of the melt extrusion mechanism, and cutting speed of the pelletizer through the touch screen.

[0021] Step 2: Prepare raw materials. The raw materials for non-metallic explosion-proof balls consist of nylon, 12% carbon fiber conductive filler, 10% main flame retardant, 100% flame retardant synergist, 2% additives, 0.2% anti-drip agent, 0.15% antioxidant, and 3% toughening agent.

[0025] Compared with the prior art, the beneficial effects of the present invention are: the non-metallic explosion-proof ball water-cooled pelletizer and its method of use directly extrudes the material into the cooling liquid and completes the pelletizing in the cooling liquid, which can improve the cooling effect. At the same time, the liquid after absorbing the heat of the material can be cooled down for recycling. The specific details are as follows:

[0026] 1. Through the threaded transmission between the first movable cylinder and the first reciprocating screw, the rack moves horizontally back and forth, and through the meshing transmission with the gear, the movable shaft rotates, thereby driving the scooping net to scoop up the particles. When the scooping net rotates clockwise, it can scoop up the particles and convey them to the receiving net. The material falls onto the receiving net for temporary draining. Then, the scooping net rotates counterclockwise and contacts the lower end face of the receiving net. By striking it, the receiving net can be driven to rotate, so that the drained material can fall onto the conveyor belt for conveying.

[0027] 2. The second movable cylinder drives the piston plate to rise and fall through the threaded transmission with the second reciprocating screw. When the piston plate rises, it can draw the liquid in the fixed box into the cooling box through the water supply pipe. After cooling, the piston plate falls and transfers the liquid in the cooling box to the fixed box through the return water pipe, realizing the recycling of liquid.

[0028] Furthermore, during the lifting and lowering of the piston plate, the gas at the top of the cooling box can be squeezed into the fixed cavity through the gas delivery pipe, and then discharged through the gas outlet and blown onto the material on the conveyor belt to dry the moisture on its surface.

[0038] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0039] Please see Figures 1-8 The present invention provides the following technical solution:

[0040] Example 1: To address the problems existing in the prior art, this example provides the following technical solution: a non-metallic explosion-proof ball water-cooled pelletizer, comprising a fixed box 1, a pelletizing blade 2 rotatably mounted on the inner wall of the fixed box 1 and driven by a motor, and the fixed box 1 containing liquid for cooling the material, and a material extrusion mechanism mounted on the side of the fixed box 1; further comprising: a scooping mechanism, located inside the fixed box 1, which intermittently scoops particles from the liquid inside the fixed box 1, and is connected to a circulation mechanism via a pulley mechanism; the circulation mechanism is located on the top of the fixed box 1 and cools the liquid inside the fixed box 1 by circulating the liquid; and a conveyor belt 21, installed on the side of the fixed box 1, used to convey the pelletized material.

[0041] Most existing pelletizers use liquid spraying to cool the material before cutting. However, this cooling method is not thorough enough, leaving some unformed particles in the center of the material, which affects the smoothness of pelletizing. Figures 1-5 and Figure 8As shown, the retrieval mechanism includes a movable shaft 3 that rotates through the fixed box 1, and a retrieval net 4 is fixed to the side of the movable shaft 3. The edge of the retrieval net 4 is in close contact with the inner bottom surface of the fixed box 1, and the rotation angle of the retrieval net 4 is less than 360°. A gear 5 is fixedly sleeved at the end of the movable shaft 3, and a rack 6 is meshed with the lower part of the gear 5. The side of the rack 6 slides in close contact with the side of the fixed box 1, and a first reciprocating screw 7 is fixed at the end of the rack 6. A first movable cylinder 8 is threaded on the outer side of the first reciprocating screw 7, and the first movable cylinder 8 rotates through the side of the protective box 9. The protective box 9 is fixed to the side of the fixed box 1, and the first movable cylinder 8 is connected to the output shaft of the motor through a belt pulley mechanism. After the material is granulated by the pelletizer 2, it is placed in the cooling liquid of the fixed box 1, which can cool it down and clean the particles. Then, driven by the motor, it is transported by belt pulley. The wheel mechanism drives the first movable cylinder 8 to rotate. Through the threaded transmission between the first movable cylinder 8 and the first reciprocating screw 7, the rack 6 can be driven to reciprocate horizontally. During the movement, the movable shaft 3 is driven to rotate through the meshing transmission with the gear 5. The movable shaft 3 can drive the scooping net 4 to rotate in the fixed box 1 to scoop up the particles. When the scooping net 4 rotates clockwise, it can scoop up the particles and convey them to the receiving net 22. When the scooping net 4 comes into contact with the receiving net 22, the vibration generated by the collision between the two causes the material to fall onto the receiving net 22 for temporary drainage. The excess liquid flows into the fixed box 1 for continued use. Afterward, the scooping net 4 rotates counterclockwise to contact the lower end face of the receiving net 22. By striking it, the receiving net 22 can be driven to rotate. At this time, the receiving net 22 rotates to an inclined state, so that the drained material can fall onto the conveyor belt 21 for conveying. Therefore, by driving the forward and reverse rotation of the scooping net 4 through the movable shaft 3, the intermittent scooping of the material is achieved.

[0042] Example 2: In existing pelletizers, prolonged contact between the cooling liquid and the high-heat material causes the overall temperature of the liquid to rise. When the liquid needs to be recycled, this affects subsequent cooling of the material. Therefore, there is a lack of a structure to cool the cooling liquid. This example addresses this issue through the following technical solution: Figure 2 and Figures 6-8As shown, the motor's output shaft is driven by a bevel gear set 10 meshing with a transmission shaft 11, and the transmission shaft 11 is connected to the second movable cylinder 12 via a pulley mechanism. The circulation mechanism includes a second reciprocating screw 13 threaded through the interior of the second movable cylinder 12, and a piston plate 14 is fixed to the bottom of the second reciprocating screw 13. The second movable cylinder 12 is rotatably mounted on the top of the cooling box 15, and the cooling box 15 is fixed to the top of the fixed box 1. The edge of the piston plate 14 slides against the inner wall of the cooling box 15. The cooling tank 15 is equipped with a water supply pipe 16 and a return pipe 17 at the lower ends of both sides, forming a liquid circulation channel with the cooling tank 15, water supply pipe 16, return pipe 17, and fixed box 1. Both the water supply pipe 16 and return pipe 17 are equipped with one-way valves. The upper end of the side of the cooling tank 15 is fixedly connected to one end of the air supply pipe 18, and the other end of the air supply pipe 18 is fixed to the fixed box 1. The cooling tank 15 is interconnected with the interior of the fixed cavity 19 through the air supply pipe 18, and the fixed cavity 19 is located within the fixed box 1. Inside box 1; air vents 20 are evenly provided on one side of the fixed box 1 near the conveyor belt 21, and a receiving mesh 22 is elastically rotatable on the inclined surface on the right side of the fixed box 1. The upper end of the receiving mesh 22 is inclined, and the lower end of the receiving mesh 22 is arc-shaped. The motor shaft can also drive the transmission shaft 11 to rotate through the meshing of the bevel gear group 10. The transmission shaft 11 drives the second movable cylinder 12 to rotate through the belt pulley mechanism. Then, the second movable cylinder 12 drives the piston plate 14 to rise and fall through the threaded transmission with the second reciprocating screw 13. When the piston plate 14 rises, it can draw the liquid in the fixed box 1 into the cooling box 15 through the water supply pipe 16. After cooling, the piston plate 14 descends and transfers the liquid in the cooling box 15 back to the fixed box 1 through the return water pipe 17, realizing the recycling of the liquid. During the lifting and lowering process of the piston plate 14, it can also squeeze the gas at the top of the cooling box 15 into the fixed cavity 19 through the air supply pipe 18, and then discharge it through the air outlet 20, blowing it onto the material on the conveyor belt 21 to dry the moisture on its surface.

The carbon fiber conductive filler is conductive carbon fiber, the main flame retardant is red phosphorus masterbatch, the flame retardant synergist is anhydrous zinc borate, the additive is silicone, the anti-drip agent is nano-organic montmorillonite, the antioxidant is BASF 1098, and the toughening agent is POE.

[0046] Step 3: Extrusion and pelletizing. While the material is being extruded, the motor is started to drive the pelletizing blade 2 to rotate and pelletize. Both the extruded material and the pelletizing blade 2 are inside the cooling liquid, so they can be cooled completely.
