Description

Technical Field

[0001] The invention relates to the technical field of tire processing devices, in particular to a raw material extrusion device for tire processing. Background Art

[0002] Automobile tires are one of the important parts of automobiles. They are in direct contact with the road surface and work together with the automobile suspension to mitigate the impact of the car when it is driving, ensuring that the car has good ride comfort and driving smoothness; ensuring good adhesion between the wheels and the road surface; improving the car's traction, braking and passability; bearing the weight of the car, the important role played by tires on the car is increasingly valued by people. The airtight layer of automobile tires needs to extrude the molten rubber material and shape the molten rubber material into long strips. In order to improve the production efficiency of raw materials, extrusion devices are used to assist processing.

[0003] Specifically, in the process of using the spiral blades of the extrusion device to extrude the molten raw material, the spiral blades will drive the raw material to one side during rotation, but the extrusion will drive the raw material to move. During the movement of the raw material, air will be carried to cover the inside of the raw material, thereby causing bubbles to be filled into the raw material. If the raw material contains bubbles and is squeezed out, it will cause defects in the extruded long strips of raw material, affecting the product quality of the raw materials for tire production. So far, we have proposed a raw material extrusion device for tire processing. Summary of the invention

[0004] In view of the shortcomings of the existing raw material extrusion devices for tire processing, the present invention provides a raw material extrusion device for tire processing, which has the advantage that when the spiral blade is rotated to drive the raw material extrusion, a piston is installed inside the movable bin. When the piston pushes the raw material to be extruded into the extrusion tube, the appearance of air in the raw material inside the extrusion tube is reduced, which causes bubbles to appear after the raw material is extruded, thereby solving the problems raised in the above-mentioned background technology.

[0005] The present invention provides the following technical solution: a raw material extrusion device for tire processing comprises a hot melt tank, an upper cover is installed at the upper end of the hot melt tank, a rotating rod is arranged in the middle of the upper cover, a stirring rod is fixedly connected to the lower part of the rotating rod, a first water pipeline is fixedly connected to the outside of the rotating rod, a second water pipeline is fixedly connected to the outside of the first water pipeline, a discharge pipe is installed in the middle of the lower end of the hot melt tank, a movable bin is fixedly connected to the lower part of the discharge pipe, an extrusion pipe is fixedly connected to one side of the movable bin, a piston is movably sleeved inside the extrusion pipe, a push rod is fixedly connected to the end of the piston, a positioning pin is movably sleeved inside the push rod, a rotating disk is fixedly connected to the lower part of the positioning pin, a sealing sleeve is installed at the lower end of the rotating disk, a fan blade is movably sleeved inside the sealing sleeve, a blade is fixedly connected to the outside of the fan blade, and a forming pipe is fixedly connected to the other end of the extrusion pipe.

[0009] Preferably, a first one-way valve and a second one-way valve are respectively installed inside the discharge pipe and the extrusion pipe and at the connection with the movable bin, the piston is in close contact with the inner wall of the movable bin, and the first one-way valve and the second one-way valve are in the same direction.

[0010] Preferably, a transverse groove is provided inside the push rod, and the positioning pin is movably sleeved inside the transverse groove.

[0011] Preferably, the rotating disk and the fan blades are fixedly connected to each other, and the blades are arranged at equal intervals outside the fan blades.

[0012] Preferably, a first condenser and a second condenser are fixedly connected to both sides of the fan blade, a solidification device is fixedly connected to the outside of the end of the formed pipe, a third condenser is installed inside the solidification device, and the first condenser and the second condenser are connected at both ends of the solidification device.

[0013] Preferably, a spiral blade is installed inside the extrusion tube, and a motor is installed outside the spiral blade.

[0014] Compared with the existing raw material extrusion device for tire processing, the present invention has the following beneficial effects: 1. The raw material extrusion device for tire processing is arranged inside the sealing pad through the second water pipeline to maintain its sealing performance. At the same time, the water inlet pipe drives the raw material to be transported to the inside of the second water pipeline. At the same time, the second water pipeline drives the heating liquid to be transported to the inside of the vertical pipe. At the same time, during the rotation of the vertical pipe, the raw material can be stirred to improve the synchronous heating of the raw material during the stirring process and improve the hot melt stirring efficiency of the raw material.

[0015] 2. The raw material extrusion device for tire processing, when the push rod rotates, the rotating disk rotates, and the rotating disk drives the push rod to move back and forth inside the movable bin, and at the same time, the push rod drives the piston to move inside the movable bin. At the same time, during the circulation of the piston inside the movable bin, the first one-way valve and the second one-way valve can be driven to open, and the raw material inside the hot melt tank is absorbed and transported to the inside of the extrusion tube, thereby increasing the pressure during raw material extrusion, reducing the bubbles in the raw material, which affects the quality of the raw material, and avoiding the backflow of the extruded raw material.

[0016] 3. The raw material extrusion device for tire processing starts the motor to control the synchronous rotation of the rotating disk and the fan blades. The rotating disk rotates to drive the raw material extrusion to provide power, and the fan blades drive the blades to rotate. The blades drive the condensate to circulate and transport to provide power, ensuring that the raw material is automatically condensed and formed during the extrusion process, avoiding the need to cool the raw material through water during subsequent raw material extrusion, which causes water resource pollution.

The fan blades 24 drive the push rod 20 to rotate. During the rotation of the push rod 20, the piston 17 can be driven to move back and forth inside the movable chamber 15. At the same time, when the piston 17 moves, it drives the first one-way valve 18 or the second one-way valve 19 to open, so that the raw materials inside the hot melt tank 1 can be absorbed and squeezed into the extrusion tube 16, thereby increasing the pressure when the raw materials are extruded and reducing the gaps between the raw materials. The fan blades 24 rotate to drive the condensed liquid to circulate and be transported to the inside of the third condensation tube 31. At the same time, the water outlet 13 can condense the raw materials passing through the inside of the forming pipe 29 to avoid the need for condensation of the raw materials in water after extrusion, which leads to pollution of water resources.
