[0027] The principles and characteristics of the utility model are described below in combination with the drawings, and the examples are only used to explain the utility model and are not used to limit the scope of the utility model.

[0028] The utility model provides the following preferred embodiment:

[0029] Embodiment one, as Figures 1-6 Shown, a plastic particle water tray cutting mechanism, including bottom plate 1 still includes transport mechanism, cutting mechanism and and cleaning mechanism,

[0030] Transport mechanism includes discharge tray 3 multiple discharge holes 4 and conveying assembly, conveying assembly sets up at the top of bottom plate 1, discharge tray 3 sets up at one end of conveying assembly, multiple discharge holes 4 all are set up on discharge tray 3,

[0031] Cutting mechanism includes cutterhead 5, shell 2 and rotating assembly, shell 2 sets up at the top of bottom plate 1, rotating assembly sets up in shell 2 interior, cutterhead 5 sets up on rotating assembly,

[0032] Cleaning mechanism includes sliding assembly, transmission assembly and cleaning assembly, transmission assembly sets up at one side of shell 2, sliding assembly sets up at the top of shell 2, cleaning assembly sets up between shell 2 and sliding assembly.

[0033] As Figures 1-6 Shown, conveying assembly includes transport pipe 6, auger 7 and first motor 9, transport pipe 6 sets up at the top of bottom plate 1, the top of transport pipe 6 is provided with feed inlet 8, first motor 9 is fixedly set up at one end of transport pipe 6, auger 7 is fixedly connected with the output shaft of first motor 9, auger 7 rotationally sets up in transport pipe 6, discharge tray 3 is fixedly set up at one end of transport pipe 6 away from first motor 9,

[0034] When needing to cut plastic particles, first melt state plastic is placed into feed inlet 8, the plastic in feed inlet 8 is driven under auger 7 and flows in transport pipe 6, and is extruded under the thrust of auger 7 on the discharge hole 4 set on the surface of discharge tray 3, when the plastic is extruded, the cutting mechanism on the other side of discharge tray 3 will cut the plastic extruded from discharge hole 4, to form plastic particles.

[0035] As Figures 1-6 Shown, rotating assembly includes second motor 10, rotating shaft 11, blade 12 and L-shaped plate 13, L-shaped plate 13 is fixedly set up at one end of shell 2, second motor 10 is fixedly set up at the top of L-shaped plate 13, rotating shaft 11 rotationally sets up in shell 2, and rotating shaft 11 is fixedly connected with the output end of second motor 10, blade 12 is set up on the outer wall of rotating shaft 11, cutterhead 5 is set up at one end of rotating shaft 11 away from second motor 10, and the outer wall of cutterhead 5 is provided with multiple blades 14, and discharge outlet 35 is set up below shell 2.

[0036] When the plastic extruded from the discharge hole 4 is cut, the second motor 10 drives the rotating shaft 11 to rotate, drives the cutter head 5 to rotate, and further drives the plurality of blades 14 to rotate, so as to cut the extruded plastic. At the same time, the water injection pipe 28 above the shell 2 is connected to an external water source to inject water into the shell 2, so that the plastic particles just cut by the blades 14 enter the water for rapid cooling. When the rotating shaft 11 drives the blades 14 to rotate, the blades 12 on the surface of the rotating shaft 11 also rotate synchronously. Through the stirring of the blades 12, the plastic particles are stirred to prevent a plurality of plastic particles with high temperature from adhering together, thereby affecting the product quality. The stirred plastic particles and water are discharged together through the discharge port 35.

[0037] As shown in Figures 1-6 , the cleaning assembly includes a water injection pipe 28, a drainage pipe 29, an impact pipe 31, a water spraying pipe 32, a storage barrel 30, and two one-way valves 34. The storage barrel 30 is installed above the shell 2, the water injection pipe 28 is arranged above the shell 2, the two ends of the drainage pipe 29 are respectively communicated with the water injection pipe 28 and the storage barrel 30, and the two ends of the impact pipe 31 are respectively communicated with the storage barrel 30 and the water spraying pipe 32. Specifically, a plurality of nozzles are installed on the surface of the water spraying pipe 32, and the two one-way valves 34 are arranged on the drainage pipe 29 and the impact pipe 31, respectively.

[0038] After a long time of cutting, the surface of the blades 14 may be adhered or have plastic particles. These plastic particles will affect the cutting of the cutter. Through the transmission assembly and the sliding assembly, the sliding rod 26 and the piston 27 slide in the storage barrel 30. When the piston 27 moves away from the sliding rod 26, the water in the storage barrel 30 is squeezed out through the impact pipe 31, and the water is sprayed to the surface of the blades 14 through the water spraying pipe 32. Because the diameter of the impact pipe 31 is smaller than that of the storage barrel 30, the water flow is accelerated, and finally the water spraying pipe 32 is used to flush the blades 14, so that the plastic particles adhered to the blades 14 fall off.

[0039] When the piston 27 moves towards the sliding rod 26, under the action of negative pressure, the water in the water injection pipe 28 can enter the storage barrel 30 through the drainage pipe 29 for storage, so as to facilitate the squeezing out of water for the next time, thereby facilitating the next time of flushing.

[0040] As shown in Figures 1-6 , the transmission assembly includes a belt 19, a vertical plate 20, a transmission rod 21, two belt pulleys 18, and two support plates 22. The vertical plate 20 is arranged above the bottom plate 1, the two support plates 22 are fixedly arranged on one side of the vertical plate 20, the transmission rod 21 is rotatably arranged on the two support plates 22, the two belt pulleys 18 are fixedly arranged on the transmission rod 21 and the rotating shaft 11, respectively, and the belt 19 is sleeved on the two belt pulleys 18.

[0041] It should be noted that in actual use, the diameter of the pulley 18 on the transmission rod 21 is smaller than that of the pulley 18 on the rotating shaft 11.

[0042] When the rotating shaft 11 rotates, it drives one pulley 18 to rotate, which drives another pulley 18 to rotate through the belt 19, thereby driving the transmission rod 21 to rotate. When the transmission rod 21 rotates, it drives the rotating disc 23 to rotate. The rotating shaft 11 drives the blade 14 to rotate by the force of the transmission rod 21, reducing the number of driving sources.

[0043] As shown in Figures 1-6 , the sliding assembly includes a rotating disc 23, a rotating rod 24, a hinged rod 25, a sliding rod 26, and a piston 27. The rotating disc 23 is fixedly arranged at one end of the transmission rod 21 away from the pulley 18. The rotating rod 24 is fixedly arranged at one side of the rotating disc 23 away from the transmission rod 21. The hinged rod 25 is rotatably connected to the rotating rod 24 and the sliding rod 26 at both ends. The piston 27 is fixedly arranged at one end of the sliding rod 26 away from the hinged rod 25. The sliding rod 26 is slidingly arranged at one end of the storage barrel 30. The piston 27 is slidingly arranged inside the storage barrel 30.

[0044] When the rotating disc 23 rotates, it drives the rotating rod 24 to rotate. When the rotating rod 24 rotates, it drives the sliding rod 26 and the piston 27 to slide inside the storage barrel 30 through the hinged rod 25.

[0045] As shown in Figures 1-6 , the inside of the shell 2 is provided with a fixed plate 33. One end of the fixed plate 33 away from the shell 2 is fixedly connected with the water spraying pipe 32.

[0046] The fixed plate 33 fixes the water spraying pipe 32, preventing the water flow from washing away the water spraying pipe 32, and allowing the spraying direction of the water spraying pipe 32 to be aligned with the blade 14, thereby improving the spraying efficiency.
