Description

Technical Field

[0001] The invention relates to the technical field of mixed plastic granulation, in particular to a short screw mixed plastic granulation production line. Background Art

[0002] The short screw mixed plastic granulation production line usually consists of an extruder, a feeding device, a heating and cooling system, a cooling water tank and a granulation device. The working process of the short screw mixed plastic granulation production line is generally as follows: first, the plastic raw material is added to the feeding device, and the raw material is transported to the screw of the extruder through the feeding device; then in the extruder, the screw rotates to transport, compress, mix and plasticize the material, and the heating and cooling system heats or cools the material to reach the appropriate processing temperature and viscosity; the plasticized material is extruded through the die head of the extruder to form a continuous strip or sheet material, which is then cooled through a cooling water tank, and finally the extruded material is cut into uniform plastic particles by the granulation device.

[0003] In the prior art, the cooling water trough is usually in the shape of a long rectangular parallelepiped. Since the temperature of the material rod extruded by the extruder is relatively high, in order to meet the cooling requirements, the length of the water trough is usually relatively long (generally about 3 meters), which requires a large site area, and the cooling speed is slow, which is not convenient for rapid cooling. Moreover, after the extruded plastic passes through the cooling water trough, its surface generally adheres to a lot of moisture. If this moisture is not dried, it will affect the quality of the subsequent plastic particles, causing them to stick together and mold during storage. Moreover, when the subsequent plastic particles are used for injection molding and other processing, the moisture may cause quality problems such as bubbles and surface defects in the products. In the prior art, a single surface of the extruded plastic is often dried by simple air cooling, while the bottom is difficult to dry, resulting in the extruded plastic cannot be evenly dried. Therefore, it is of great significance to study a new short screw mixed plastic granulation production line to solve the above problems. Summary of the invention

[0052] In this embodiment: through the transmission of the driving assembly 506 and the transmission assembly 508, the transmission assembly 508 drives the connecting rod assembly 509 to move, and the connecting rod assembly 509 drives the lower roller 5071 to move, so that the lower roller 5071 cooperates with the second spring 5075 to realize the reciprocating translational motion of the lower roller 5071, and the lower roller 5071 cooperates with the upper roller 5063 to realize the function of twisting the plasticized raw material, and the plasticized raw material can be twisted from the upward extension of the rotating drum 5031, so that when the cooling assembly 502 is sprayed again, it can cooperate with the twisted plasticized raw material for uniform spraying, which can further improve the cooling effect and facilitate the rapid molding of the plasticized raw material.

[0053] The working principle of the present invention is as follows: when plastic granulation is performed, the extrusion device 400 is controlled by the control device 200 to operate, the extrusion device 400 can perform pressurized plasticization treatment on the raw material, and the second motor 5061 drives the upper roller 5063 to rotate, so that the upper roller 5063 drives the first gear 5064 and the second gear 5072 to transmit, and the second gear 5072 drives the lower roller 5071 to rotate, so that the upper roller 5063 and the lower roller 5071 cooperate to convey the plasticized raw material;

[0054] The plasticized raw material is spirally transported from the drum 5031, and the first motor 5035 drives the belt transmission structure 5036 to drive the drum 5031 to rotate, and the drum 5031 drives the spiral blades 5033 to rotate, and the two spiral blades 5033 realize front-to-back convection, thereby rapidly cooling the plasticized raw material, and the liquid in the water tank 501 can be extracted by the water pump 5021 and transported upward, so that the liquid is further cooled by the cooling device 5023, and then sprayed from the spray head 5024 to cool the plasticized raw material;

[0055] Secondly, the rotation of the upper roller 5063 also drives the first bevel gear 5062 and the second bevel gear 5084 to transmit, the second bevel gear 5084 drives the rotating rod 5083 to rotate, the rotating rod 5083 drives the cam 5082 to rotate, the cam 5082 squeezes the ball 5092, the ball 5092 drives the lower roller 5071 to slide on the square plate 5073 through the annular ring 5091, so that the lower roller 5071 drives the second spring 5075 to deform, when the convex surface of the cam 5082 moves away from the ball 5092, the second spring 5075 drives the lower roller 5071 to reset, when the convex surface of the cam 5082 squeezes the ball 5092 again, the lower roller 5071 moves again, so that The cam 5082 can cooperate with the second spring 5075 to realize the reciprocating motion of the lower roller 5071, so that the lower roller 5071 can cooperate with the upper roller 5063 to realize the operation of twisting the plasticized raw material, and remove moisture by twisting. At the same time, the annular ring 5091 drives the swing rod 5094 to swing back and forth, so that the swing rod 5094 drives the shaft body 5058 to reciprocate through the opening 5095, and the shaft body 5058 drives the piston rod 5056 to reciprocate. The piston rod 5056 switches the air intake through two one-way valves 5057 and exhausts one-way through the one-way hose 5054, so that the connecting pipe 5051 supplies air and exhausts air through the air-drying head 5052, thereby performing an air-drying operation on the plasticized raw material;

[0056] After air drying, the plasticized raw material enters the granulation equipment 300 for granulation and discharging operation.
