The second valve is intermittently opened under the control of the PLC, when the second valve is opened, air in the first branch pipe 20 can be discharged through the driving pipe 22, so that the driving plate 23 is driven to move upwards, the first spring 24 is stretched, so that a nut of the ball screw pair 27 is driven to move along a screw of the ball screw pair 27, so that the screw of the ball screw pair 27 can be driven to rotate, the second gear 28 is driven to rotate, the first gear 29 is driven to rotate through the meshing of the first gear 29 and the second gear 28, so that the knocking block 32 can be driven to rotate, when the second valve is closed, air in the first branch pipe 20 cannot be discharged from the driving pipe 22, so that the driving plate 23 is driven to move downwards under the action of the restoring force of the first spring 24, so that the screw of the ball screw pair 27 can be driven to rotate reversely, so that the function of reverse rotation of the driving plate 32 is realized, so that the knocking block 32 can knock the feeding pipe, make the inlet pipe take place to shake to can accelerate the speed that the raw materials passes through the inlet pipe, promote reinforced work efficiency, also can reduce the raw materials simultaneously and block up in the inside of inlet pipe, prevent to influence the normal clear of reinforced work, the practicality is higher.

When the main body 2 is cooled, the water pumping assembly is controlled to work, clear water between the two fixing plates 21 can be guided into the cooling pipe 10, then the clear water is guided into the water tank 5 through the connecting pipe 11, heat on the main body 2 can be taken away through the flow of the clear water on the cooling pipe 10, so that the work of cooling and radiating the interior of the main body 2 can be realized, the phenomenon that plastic cannot be solidified and formed due to overhigh extrusion temperature is prevented, the influence on the quality of finished products is avoided, the reliability of the equipment is improved, when water absorbing heat flows in the connecting pipe 11, the rotating unit can be driven to work, the fan blades 17 are driven to rotate, the flow rate of air is accelerated, external air can enter the interior of the water tank 5 after impurity removal through the filter screen, then the air flows into the first branch pipe 20 through the second branch pipe 19, and flowing air exists in the second branch pipe 19, thereby can absorb the heat of water, thereby can take away the heat of water, realize the function of feedwater cooling, after the temperature of the water of the one side that is close to connecting pipe 11 of fixed plate 21 reduces, control first valve is opened, make the water of the one side that is close to connecting pipe 11 of fixed plate 21 can flow in between two fixed plates 21, thereby make the water after the cooling again by leading-in cooling pipe 10 in, thereby can realize the cyclic utilization of water, make the water in the leading-in cooling pipe 10 can keep lower temperature, thereby can be better absorb the heat on main part 2, thereby can promote the cooling radiating effect, the practicality is higher. The flow of the air in first branch pipe 20, can drive assembly work, make first gear 29 rotate, thereby can drive and strike piece 32 and rotate, when strike piece 32 rotate to support with the lug and lean on when, can drive and strike piece 32 and remove to the direction of keeping away from the inlet pipe, tensile elasticity rope 30, when strike piece 32 rotate to support with the lug and lean on when, under the effect of the restoring force of elasticity rope 30, can drive and strike piece 32 and remove to the direction that is close to the inlet pipe, through the rotation of striking piece 32, can be so that strike the piece 32 discontinuous and strike the inlet pipe, make the inlet pipe take place the shake, thereby can accelerate the speed that the raw materials passes through the inlet pipe, promote reinforced work efficiency, also can reduce the inside of raw materials jam at the inlet pipe simultaneously, prevent to influence the normal clear of reinforced work, the practicality is higher.

Compared with the prior art, the plastic extruder with the cooling function can realize the work of cooling and radiating the interior of the main body 2 through the cooling mechanism, prevent the plastic from being solidified and formed due to overhigh extrusion temperature, thereby avoiding the influence on the quality of finished products and improving the reliability of equipment, compared with the prior cooling mechanism, the cooling mechanism can also carry out air cooling work on water, thereby realizing the recycling of the water, leading the water led into the cooling pipe 10 to keep lower temperature, better absorbing the heat on the main body 2, thereby improving the cooling and radiating effect, and has higher practicability, the inlet pipe of the knocking block 32 can be knocked discontinuously through the auxiliary mechanism, so that the inlet pipe shakes, thereby accelerating the speed of raw materials passing through the inlet pipe, improving the working efficiency of feeding, and simultaneously reducing the blockage of the raw materials in the inlet pipe, prevent to influence the normal clear of reinforced work, the practicality is higher, compares with current complementary unit, and this complementary unit constructs as an organic whole link gear with cooling down, and the practicality is higher.

In light of the foregoing description of the preferred embodiment of the present invention, many modifications and variations will be apparent to those skilled in the art without departing from the spirit and scope of the invention. The technical scope of the present invention is not limited to the content of the specification, and must be determined according to the scope of the claims.
