[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0024] Reference Figure 1-5 A discharge device suitable for high-viscosity plastic particles includes a base 1, a heating cylinder 2 on the base 1, a feeding hopper 3 on the heating cylinder 2, a screw rod 4 inside the heating cylinder 2, the screw rod 4 being driven by a motor, a cooling mechanism 5 at the end of the heating cylinder 2 away from the feeding hopper 3, a cutting mechanism 6 on the cooling mechanism 5, and a storage tank 7 below the cutting mechanism 6.

[0025] When using this device, plastic raw materials are fed into the heating cylinder 2 through the feeding hopper 3. The heating cylinder 2 heats the plastic raw materials, and then the motor drives the screw rod 4 to rotate, thereby pushing the plastic raw materials in the heating cylinder 2 towards the cooling mechanism 5. The plastic strips extruded from the heating cylinder 2 enter the cooling mechanism 5, allowing the plastic strips to cool and solidify rapidly. The cooled plastic strips enter the cutting mechanism 6, which cuts the plastic strips into granules and discharges them into the storage bin 7, thus completing the collection of plastic granules.

[0026] Specifically, in this embodiment, a discharge plate 8 is threadedly installed at one end of the heating cylinder 2 near the cooling mechanism 5. The discharge plate 8 has several rows of discharge holes 9, so that the plastic raw material heated and melted in the heating cylinder 2 will be discharged from the heating cylinder 2 through the discharge plate 8 under the extrusion action. Then, through the arrangement of several rows of discharge holes 9 on the discharge plate 8, the plastic raw material will be extruded into several plastic strips at the same time through several rows of discharge holes 9, thereby improving the production efficiency of plastic strips.

[0027] Specifically, in this embodiment, a filter screen 10 is provided between the screw rod 4 and the discharge plate 8, so that the heated and melted plastic raw material will first come into contact with the filter screen 10 before entering the discharge plate 8, thereby filtering the plastic raw material through the filter screen 10 before it is extruded, thereby filtering out impurities in the plastic raw material and further improving the purity of the plastic raw material.

[0028] Specifically, in this embodiment, the cooling mechanism 5 includes a water storage tank 51 installed on the base 1, a cooling box 52 installed on the water storage tank 51, and a plurality of through holes 53 opened on the cooling box 52. The plurality of through holes 53 correspond to the positions of the discharge hole 9. The size of the through holes 53 is larger than the size of the discharge hole 9, so that the extruded plastic strip will enter the cooling box 52 through the plurality of through holes 53, be cooled by the cold water in the cooling box 52, and then enter the cutting mechanism 6 through the through holes 53 on the other side of the cooling box 52, so that the plastic strip can be quickly formed before the cutting process.

[0029] Specifically, in this embodiment, a water outlet pipe 54 is connected between the water storage tank 51 and the cooling tank 52. One end of the water outlet pipe 54 is connected to a water pump, so that when the water level in the cooling tank 52 drops, water can be introduced into the water storage tank 51 through the water outlet pipe 54, thereby ensuring that the water level in the cooling tank 52 remains at the same height, achieving the effect of cooling all the plastic strips. At the same time, the water in the cooling tank 52 can circulate with the water in the water storage tank 51, thereby keeping the water in the cooling tank 52 at a low temperature.

[0030] Specifically, in this embodiment, a plurality of guide plates 55 are installed inside the cooling box 52. Each guide plate 55 has a groove 56. The groove 56 corresponds to the position of each row of through holes 53, so that when the plastic strip enters the cooling box 52 through the through hole 53, it will enter the guide plate 55. The guide plate 55 limits the movement direction of the plastic strip, so that the plastic strip can accurately enter the through hole 53 on the other side and move to the outside of the cooling box 52 through the through hole 53 on that side.

[0031] Specifically, in this embodiment, the cutting mechanism 6 includes several cutting tables 61 mounted on the cooling box 52. The same blade assembly 62 is slidably connected to the several cutting tables 61. The blade assembly 62 is composed of several blades connected together. The output shaft of the cylinder 63 is connected to the blade assembly 62. The cylinder 63 is mounted on the side of the cooling box 52 near the storage tank 7. When the plastic strip moves to the cutting table 61, the cylinder 63 is activated. The cylinder 63 moves up and down reciprocatingly, driving the blade assembly 62 to move up and down in a circular motion at the same time, thereby achieving the purpose of cutting the plastic strip.

[0032] The above are merely preferred embodiments of this utility model, but the scope of protection of this utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in this utility model, based on the technical solution and inventive concept of this utility model, should be included within the scope of protection of this utility model.
