Description

Technical Field

[0001] This invention relates to the field of tire processing equipment technology, specifically to a raw material extrusion device for tire processing. Background Technology

[0002] Car tires are one of the most important components of a car. They come into direct contact with the road surface and, together with the car's suspension, mitigate the impact of driving, ensuring good ride comfort and smoothness; ensuring good adhesion between the wheels and the road surface; improving the car's traction, braking, and handling; and bearing the weight of the car. The important role of tires in automobiles is increasingly recognized. The airtight layer of a car tire requires the extrusion of molten rubber material, shaping the molten rubber material into a long strip. To improve raw material production efficiency, extrusion equipment is used to assist in the processing.

[0003] Specifically, in the process of extruding molten raw materials using the spiral blades of the extrusion device, the spiral blades rotate and push the raw materials to one side. However, this pushing will cause the raw materials to move. During the movement of the raw materials, air will be carried and covered inside the raw materials, resulting in air bubbles being injected into the raw materials. If the raw materials contain air bubbles and are extruded, it will cause defects in the extruded strip-shaped raw materials, affecting the product quality of tire production raw materials. Therefore, we propose a raw material extrusion device for tire processing. Summary of the Invention

[0004] To address the shortcomings of existing tire processing raw material extrusion devices, this invention provides a tire processing raw material extrusion device that features a piston installed inside the movable chamber during the raw material extrusion process driven by the rotation of the spiral blades. When the piston pushes the raw material into the extrusion tube, it reduces the air formation inside the extrusion tube, thus preventing air bubbles from forming after the raw material is extruded. This solves the problems mentioned in the background art.

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

[0006] Preferably, the upper cover has an inlet on one side, the hot melt tank has an opening in the middle of its lower end, and the discharge pipe is conical.

[0007] Preferably, a sealing gasket is fixedly connected inside the hot melt tank, wherein the sealing gasket is fitted onto the outside of the second water supply pipe, and an inlet pipe is installed in sequence on the hot melt tank, and the inlet pipe is interconnected with the inside of the second water supply pipe.

[0008] Preferably, a vertical pipe is fixedly connected inside the first water supply pipe, a rotating base is fixedly connected to the lower part of the vertical pipe, a water outlet pipe is fixedly connected to one side of the lower end of the hot melt tank, a water outlet is opened at the upper end of the water outlet pipe, a water outlet hole is opened inside the lower end of the rotating base, and the rotating base is kept in a close fit with the base of the hot melt tank.

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

[0010] Preferably, the push rod has a transverse groove inside, 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 on the outside of 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 to the two 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 existing raw material extrusion devices for tire processing, the present invention has the following advantages:

[0015] 1. The raw material extrusion device for tire processing is installed inside the sealing gasket through a second water supply pipe to maintain its sealing performance. At the same time, the water inlet pipe drives the raw material to be transported into the second water supply pipe, and the second water supply pipe drives the heated liquid to be transported into the vertical pipe. During the rotation of the vertical pipe, the raw material can be stirred to improve the efficiency of the raw material hot melting and stirring process by simultaneously heating the raw material.

[0016] 2. In this tire processing raw material extrusion device, 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 chamber. At the same time, the push rod drives the piston to move inside the movable chamber. During the piston's cyclical movement inside the movable chamber, it can drive the first one-way valve and the second one-way valve to open, thereby absorbing the raw material inside the hot melt tank and transporting it to the inside of the extrusion tube. This increases the pressure of the raw material during extrusion, reduces the presence of air bubbles in the raw material, thus preventing it from affecting the quality of the raw material, and also prevents the extruded raw material from flowing back.

[0017] 3. The raw material extrusion device for tire processing controls the rotating disk and fan blades to rotate synchronously by starting the motor. The rotating disk drives the raw material to be extruded, and the fan blades drive the blades to rotate, while the blades drive the condensate to circulate and provide power. This ensures that the raw material is automatically condensed and formed during the extrusion process, avoiding the need to cool the raw material with water during subsequent extrusion, which would lead to water pollution.

[0025] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present invention.

[0026] Please see Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6 A raw material extrusion device for tire processing includes a hot melt tank 1. A top cover 2 is installed at the upper end of the hot melt tank 1, sealing the upper end of the tank. A rotating rod 4 is located in the middle of the top cover 2, and a stirring rod 5 is fixedly connected to the lower part of the rotating rod 4. A first water supply pipe 6 is fixedly connected to the outside of the rotating rod 4. High-temperature liquid is transported into the interior of the first water supply pipe 6, and the first water supply pipe 6 heats the liquid during stirring, improving the heating and melting efficiency of the raw material. A second water supply pipe 7 is fixedly connected to the outside of the first water supply pipe 6. A discharge pipe 14 is installed in the middle of the lower end of the hot melt tank 1, and a movable chamber 15 is fixedly connected to the lower part of the discharge pipe 14. An extrusion pipe 16 is fixedly connected to one side of the movable chamber 15. The movable chamber 15 and the extrusion tube 16 provide power for the extrusion of raw materials. A piston 17 is movably sleeved inside the movable chamber 15. A push rod 20 is fixedly connected to the end of the piston 17. A positioning pin 22 is movably sleeved inside the push rod 20. A rotating disk 21 is fixedly connected to the lower part of the positioning pin 22. When the rotating disk 21 rotates, it controls the positioning pin 22 to drive the push rod 20 to perform cyclical motion. A sealing sleeve 23 is installed at the lower end of the rotating disk 21. A fan blade 24 is movably sleeved inside the sealing sleeve 23. The fan blade 24 drives the blade 25 to rotate. The blade 25 drives the pipeline to discharge. The blade 25 is fixedly connected to the outside of the fan blade 24. A forming pipe 29 is fixedly connected to the other end of the extrusion tube 16. The raw material is extruded through the forming pipe 29.

[0027] Please see Figure 1 The upper cover 2 has an inlet 3 on one side, and the hot melt tank 1 has an opening in the middle of the lower end. The discharge pipe 14 is conical. The raw materials for tire processing can be put into the hot melt tank 1 through the inlet 3. The raw materials are heated, melted and stirred inside the hot melt tank 1. After stirring, they are transported to the inside of the discharge pipe 14 and then to the inside of the extrusion device. The raw materials can also be discharged through the extrusion device.

[0028] Please see Figure 3A sealing gasket 8 is fixedly connected inside the hot melt tank 1. The sealing gasket 8 is sleeved on the outside of the second water supply pipe 7. A water inlet pipe 9 is installed in sequence in the hot melt tank 1. The water inlet pipe 9 is interconnected with the inside of the second water supply pipe 7. The second water supply pipe 7 is fitted inside the hot melt tank 1, while the sealing gasket 8 is clamped on the outside of the second water supply pipe 7. That is, the sealing gasket 8 seals the end of the second water supply pipe 7 and limits the second water supply pipe 7 inside the hot melt tank 1. This prevents the position of the second water supply pipe 7 from shifting when encountering pressure during the raw material stirring process. At the same time, the heating liquid can be transported to the inside of the second water supply pipe 7 and the first water supply pipe 6 through the water inlet pipe 9. The first water supply pipe 6 and the second water supply pipe 7 are used to heat and melt the raw material accumulated in the middle of the hot melt tank 1, thereby improving the hot melting efficiency of the raw material.

[0029] Please see Figure 3 and Figure 6 A vertical pipe 10 is fixedly connected inside the first water supply pipe 6. A rotating base 11 is fixedly connected to the lower part of the vertical pipe 10. A water outlet pipe 12 is fixedly connected to one side of the lower end of the hot melt tank 1. A water outlet 13 is opened at the upper end of the water outlet pipe 12. A water outlet hole is opened inside the lower end of the rotating base 11. The rotating base 11 is kept in close contact with the base of the hot melt tank 1. The rotating base 11 is installed at the lower end of the hot melt tank 1. The rotating base 11 rotates synchronously with the stirring rod 5 to avoid the rotating base 11 being fixed in position, which would cause the raw materials to stick to the outside of the rotating base 11 and affect the stirring efficiency of the raw materials. The rotating base 11 can transmit high-temperature liquid. When the lower opening of the rotating base 11 coincides with the water outlet 13, the heated liquid can be discharged. The vertical pipe 10 is set inside the hot melt tank 1. The vertical pipe 10 rotates synchronously with the stirring rod 5. The vertical pipe 10 can improve the stirring efficiency of the material motor.

[0030] Please see Figure 5 A first one-way valve 18 and a second one-way valve 19 are respectively installed inside the discharge pipe 14 and the extrusion pipe 16 and at the connection with the movable chamber 15. The piston 17 is in close contact with the inner wall of the movable chamber 15. At the same time, the first one-way valve 18 and the second one-way valve 19 are oriented in the same direction. With the first one-way valve 18 and the second one-way valve 19 installed inside the discharge pipe 14 and the extrusion pipe 16, when the piston 17 is moved to the rear end, the first one-way valve 18 opens and the second one-way valve 19 seals, so that the raw material processed inside the hot melt tank 1 can be transported to the interior of the movable chamber 15. At the same time, when the piston 17 is pushed to the front end, the second one-way valve 19 opens and the first one-way valve 18 seals, that is, the raw material is squeezed into the interior of the extrusion pipe 16 under pressure, which improves the tightness of the compression when the raw material is extruded.

[0031] Please see Figure 2The push rod 20 has a transverse groove inside, and the positioning pin 22 is movably sleeved inside the transverse groove. When the rotating disk 21 rotates, the rotating disk 21 drives the positioning pin 22 to push the push rod 20 to rotate. Thus, the push rod 20 drives the piston 17 to reciprocate in the movable chamber 15.

[0032] Please see Figure 2 The rotating disk 21 and the fan blade 24 are fixedly connected to each other. The blades 25 are arranged at equal intervals on the outside of the fan blade 24. The rotating disk 21 and the fan blade 24 are fixedly connected to each other. That is, when the fan blade 24 rotates, it can drive the rotating disk 21 to rotate synchronously. At the same time, the blades 25 are installed on the outside of the fan blade 24. When the fan blade 24 drives the blades 25 to rotate, the blades 25 can push the condensed liquid to circulate and transport.

[0033] Please see Figure 1 The fan blade 24 is fixedly connected to the two sides of the first condenser pipe 26 and the second condenser pipe 27. The solidification device 30 is fixedly connected to the outside of the end of the forming pipe 29. The solidification device 30 is installed inside the solidification device 30. The first condenser pipe 26 and the second condenser pipe 27 are connected to the two ends of the solidification device 30. The first condenser pipe 26 and the second condenser pipe 27 are installed at the two ends of the solidification device 30. At the same time, when the blade 25 rotates and drives the liquid to flow, the liquid can be transported to the inside of the solidification device 30 through the first condenser pipe 26 and the second condenser pipe 27. At the same time, the solidification device 30 can condense the raw material passing through the inside of the forming pipe 29 to avoid the raw material from being squeezed out and needing to solidify when it comes into contact with water, which would cause water pollution.

[0034] Please see Figure 1 The extrusion tube 16 has a spiral blade 28 installed inside, and a motor is installed outside the spiral blade 28. By starting the motor installed on one side of the spiral blade 28, the motor controls the spiral blade 28 to rotate, and the spiral blade 28 provides power when the raw material is extruded.

[0035] Working principle: During use, the raw materials are fed into the hot melt tank 1 through the feed inlet 3. The heating device installed inside the hot melt tank 1 is activated, and high-temperature liquid is injected from the water inlet pipe 9. This heats and melts the raw materials. Simultaneously, the rotating rod 4 drives the stirring rod 5 to stir the raw materials. The rotating rod 4 also drives the first water supply pipe 6 and the second water supply pipe 7 to rotate. The heated raw materials are sequentially fed into the stirring rod 5, the first water supply pipe 6, and the vertical pipe 10, improving the heating efficiency inside the hot melt tank 1. The heated liquid is discharged through the water outlet pipe 12, and the fan blades 24 are activated at the same time. The fan blade 24 drives the push rod 20 to rotate. During the rotation of the push rod 20, the piston 17 can 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 material inside the hot melt tank 1 can be absorbed and squeezed into the extrusion tube 16, increasing the pressure of the raw material during extrusion and reducing the gaps between the raw materials. In addition, the fan blade 24 rotates, driving the condensed liquid to circulate and transport to the interior of the third condenser tube 31. Meanwhile, the water outlet 13 can condense the raw material passing through the forming pipe 29, avoiding the need for the raw material to condense upon contact with water after extrusion, which would pollute water resources.

[0036] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
