Description

Technical Field

[0001] This utility model relates to the field of heat insulation cover technology, specifically an adjustable heat insulation cover for a rubber tire processing device. Background Technology

[0002] Rubber tires are suitable for supporting and bearing the weight of vehicles. They can withstand the weight of the vehicle, including the body, passengers, and cargo, and distribute it evenly on the road surface to ensure the stability and safety of the vehicle. At the same time, the rubber material of the tire has a certain degree of elasticity and flexibility, which can adapt to the undulations and changes of different road surfaces, reducing the bumps and vibrations of the vehicle during driving. The material of rubber tires is made by mixing raw materials such as natural rubber, synthetic rubber, carbon black, chemical additives (such as antioxidants, anti-ozone agents, anti-aging agents, etc.), fiber materials, and steel wire in a certain proportion, and then processing them through open mixing, extrusion, calendering, bead forming, cord cutting, and vulcanization.

[0003] The vulcanization process involves placing a green tire into the mold of a vulcanizing machine and vulcanizing it under appropriate time and conditions using a high-temperature heating medium such as steam. This process gives the tire the appearance, pattern, text, and tread design of a finished product. To prevent heat leakage from the inside of the mold during vulcanization, an insulation cover is usually used to enclose the mold, improving the utilization rate of the high-temperature medium and reducing energy waste. Although the insulation cover can insulate the mold, after changing the mold, different mold sizes require the same insulation cover. Since the insulation cover cannot adapt to different mold sizes and needs to be replaced, it reduces the versatility of the insulation cover. Therefore, there is an urgent need for an adjustable insulation cover for rubber tire processing equipment to solve the above problems. Utility Model Content

[0004] The purpose of this utility model is to provide an adjustable heat insulation cover for a rubber tire processing device, so as to solve the problem mentioned in the background art that after changing the mold, due to the different specifications and dimensions of the mold, it is necessary to equip it with a heat insulation cover of the same specification. Since the heat insulation cover cannot adapt to molds of different specifications and dimensions, it is also necessary to replace the heat insulation cover, which reduces the versatility of the heat insulation cover.

[0005] To achieve the above objectives, this utility model provides the following technical solution: It includes a vulcanizing machine base, a machine cover, an upper mold, and a lower mold. The lower mold is installed above the vulcanizing machine base, and the upper mold is installed inside the machine cover, with the upper mold positioned above the lower mold. A drain pipe is installed above the machine cover. An upper insulation cover is connected to the outer surface of the machine cover. A lower insulation cover is slidably connected to the outer surface of the upper insulation cover. A base one is connected to the outer surface of the lower insulation cover. A guide rod is connected to the outer surface of the base one. A base two is connected to the outer surface of the upper insulation cover. The outer surface of the guide rod is slidably connected to the inner wall of the base two. A first spring is sleeved on the outside of the guide rod. A sliding sleeve is connected to the outer surface of the upper insulation cover. A push rod is slidably connected to the inner wall of the sliding sleeve. A pressure ring is connected to the bottom end of the push rod. A second spring is sleeved on the outside of the push rod. A sealing ring is installed below the pressure ring, and the sealing ring is positioned above the upper insulation cover.

[0006] A sliding rod is installed above the vulcanizing machine base, a frame is connected to the outer surface of the machine cover, a support frame is connected to the outer surface of the frame, and the inner wall of the support frame is slidably connected to the outer surface of the sliding rod.

[0007] The top of the slide bar is connected to a top plate, and a hydraulic cylinder is installed above the top plate. The output end of the hydraulic cylinder passes through the top plate and is connected to the upper surface of the machine cover.

[0008] One end of the first spring is connected to the upper surface of the first base, and the other end of the first spring is connected to the lower surface of the second base.

[0009] The top of the guide rod is connected to a limiting block, and one side of the limiting block is in contact with the upper surface of the base.

[0010] The inner wall of the sliding sleeve is threaded with an adjusting sleeve, and one end of the adjusting sleeve located outside the sliding sleeve is connected to a four-corner head.

[0011] The outer surface of the push rod is connected to a relay ring. One side of the relay ring is in contact with the inner bottom wall of the sliding sleeve. One end of the second spring is in contact with the other side of the relay ring, and the other end of the second spring is in contact with the end of the adjusting sleeve located inside the sliding sleeve.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] 1. The adjustable heat insulation cover for a rubber tire processing device of this utility model, through the cooperation of an upper heat insulation cover, a lower heat insulation cover and a first spring, allows the lower heat insulation cover to receive support force through a base one and a guide rod, while the upper heat insulation cover provides support force to the guide rod through a base two, maintaining the stability of the lower heat insulation cover when moving up and down. The first spring provides spring push for the lower heat insulation cover to move downward and contact the vulcanizing machine base, enclosing the upper and lower molds inside. By moving the lower heat insulation cover up and down, the position and space can be expanded, enabling the enclosure of upper and lower molds of various specifications, confining heat inside the lower and upper heat insulation covers, and improving the versatility of the heat insulation cover.

[0014] 2. The adjustable heat insulation cover pressure ring, sealing ring, and second spring of the rubber tire processing device of this utility model cooperate to provide elastic pushing force to the pressure ring through the second spring, pushing the pressure ring downward to apply pressure. At the same time as the pressure ring moves downward, it pushes the sealing ring to tightly contact the connection between the upper and lower heat insulation covers, filling the gap at the connection between the upper and lower heat insulation covers and improving the sealing performance of the upper and lower heat insulation covers.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figure 1-5 This utility model provides an adjustable heat insulation cover for a rubber tire processing device, including a vulcanizing machine base 1, a machine cover 2, an upper mold 3, and a lower mold 4. The lower mold 4 is installed above the vulcanizing machine base 1, and the upper mold 3 is installed inside the machine cover 2, with the upper mold 3 located above the lower mold 4. The green tire is wrapped inside the upper mold 3 and the lower mold 4, and the green tire is heated. After being heated, the green tire has the appearance, tread, and pattern of a tire.

[0023] A drain pipe 5 is installed on the top of the hood 2. When the green tire is heated, it will generate a lot of hot air. The hot air contains harmful substances. The toxic and harmful gases are discharged to the outside through the drain pipe 5. A valve is installed on the outside of the drain pipe 5. The valve is closed during the vulcanization operation to prevent heat from leaking to the outside. The valve is opened after the vulcanization operation is completed.

[0024] The outer surface of the machine cover 2 is connected to an upper heat insulation cover 6. The outer surface of the upper heat insulation cover 6 is slidably connected to a lower heat insulation cover 7. The outer surface of the lower heat insulation cover 7 is connected to a base 1 8. The outer surface of the base 1 8 is connected to a guide rod 9. The outer surface of the upper heat insulation cover 6 is connected to a base 2 10. The outer surface of the guide rod 9 is slidably connected to the inner wall of the base 2 10. A first spring 11 is sleeved on the outside of the guide rod 9. After the lower heat insulation cover 7 moves downward, the lower heat insulation cover 7 contacts the vulcanizing machine base 1. The excessive part of the lower heat insulation cover 7 will slide upward. While the lower heat insulation cover 7 slides, it compresses the first spring 11 through the base 1 8. The base 2 10 provides support above the first spring 11. The first spring 11 provides support through the guide rod 9 to maintain the stability of the first spring 11 when it is elastically contracted. There are multiple bases 1 8, base 2 10, guide rod 9, and second spring 15, which surround the lower heat insulation cover 7.

[0025] A sliding sleeve 12 is connected to the outer surface of the upper insulation cover 6. A push rod 13 is slidably connected to the inner wall of the sliding sleeve 12. A pressure ring 14 is connected to the bottom end of the push rod 13. A second spring 15 is sleeved on the outside of the push rod 13. The sliding sleeve 12 maintains the stability of the push rod 13 when it moves. After the lower insulation cover 7 moves upward, the upper insulation cover 6 contacts the sealing ring 16. The sealing ring 16 is installed below the pressure ring 14 and is located above the upper insulation cover 6. The sealing ring 16 fills the gap between the upper insulation cover 6 and the lower insulation cover 7 to prevent heat from leaking from the gap between the lower insulation cover 7 and the upper insulation cover 6, thereby improving the sealing between the lower insulation cover 7 and the upper insulation cover 6. There are multiple sliding sleeves 12, push rods 13, and second springs 15, and they are arranged in a circle around the upper insulation cover 6.

[0026] A slide bar 17 is installed above the vulcanizing machine base 1. A frame 18 is connected to the outer surface of the machine cover 2. A support frame 19 is connected to the outer surface of the frame 18. The inner wall of the support frame 19 is slidably connected to the outer surface of the slide bar 17. There are four slide bars 17, which are located at the four corners of the vulcanizing machine base 1. There are two frames 18, which enclose the machine cover 2. Two support frames 19 are installed on the outside of each frame 18. The support frames 19 slide with the slide bar 17 to provide support for the frame 18 and the machine cover 2, and maintain the stability of the machine cover 2 when it moves up and down.

[0027] The top of the slide bar 17 is connected to the top plate 20. A hydraulic cylinder 21 is installed above the top plate 20. The output end of the hydraulic cylinder 21 passes through the top plate 20 and is connected to the upper surface of the machine cover 2. The hydraulic cylinder 21 serves as the power source to provide power for the movement of the machine cover 2. When the machine cover 2 moves up and down, it drives the upper insulation cover 6, the lower insulation cover 7 and the upper mold 3 to move at the same time.

[0028] One end of the first spring 11 is connected to the upper surface of the base 8, and the other end of the first spring 11 is connected to the lower surface of the base 10. The first spring 11 provides elastic support for the lower insulation cover 7, pushing the lower insulation cover 7 to move downward. When the lower insulation cover 7 contacts the vulcanizing machine base 1, the pushing of the first spring 11 keeps the lower insulation cover 7 in tight contact with the vulcanizing machine base 1, preventing heat from leaking to the outside from the contact point between the vulcanizing machine base 1 and the lower insulation cover 7.

[0029] The top of the guide rod 9 is connected to a limiting block 22. One side of the limiting block 22 is in contact with the upper surface of the base 10. The guide rod 9 provides resistance through the limiting ring to prevent the guide rod 9 from detaching from the base 10.

[0030] An adjusting sleeve 23 is threaded onto the inner wall of the sliding sleeve 12. A four-cornered head 24 is connected to one end of the adjusting sleeve 23 outside the sliding sleeve 12. The four-cornered head 24 facilitates contact with a wrench or other tools, allowing the adjusting sleeve 23 to rotate. Rotation of the adjusting sleeve 23 changes its position, altering the extension distance of the second spring 15 and thus changing the elastic support force of the second spring 15 on the force ring 25. A force ring 25 is connected to the outer surface of the push rod 13, with one side of the force ring 25 contacting the inner bottom wall of the sliding sleeve 12. The second spring 15 is in contact with one end of the second spring 15 and the other end of the second spring 15 is in contact with the end of the adjusting sleeve 23 located inside the sliding sleeve 12. The push rod 13 receives the elastic pushing force of the second spring 15 through the relay ring 25. After the push rod 13 moves to the upward position, it drives the relay ring 25 to move to the same position. The relay ring 25 applies pressure to the second spring 15, compressing the second spring 15. The compressed second spring 15 generates a counter-pushing force, which pushes the relay ring 25 to drive the push rod 13 to apply pressure to the pressure ring 14.

[0031] Working principle: When the upper mold 3 and lower mold 4 need to be closed, the hydraulic cylinder 21 is activated to push the machine cover 2 and the upper mold 3 to move downwards. At the same time, the machine cover 2 moves downwards, causing the upper insulation cover 6 and the lower insulation cover 7 to move downwards simultaneously. Then, the upper mold 3 and the lower mold 4 close, enclosing the green tire inside. At the same time, the lower insulation cover 7 contacts the vulcanizing machine base 1. While the lower insulation cover 7 is in contact with the vulcanizing machine base 1, it slides outside the upper insulation cover 6. Meanwhile, the upper insulation cover 6 compresses the first spring 11 through the base 2 10, and the lower insulation cover 7 receives the elastic pushing force provided by the first spring 11 through the base 1 8, so that the lower insulation cover 7 is in tight contact with the vulcanizing machine base 1. Then, the sealing ring 16 contacts the lower insulation cover 7. The sealing ring 16 is squeezed by the lower insulation cover 7 and the pressure ring 14. The sealing ring 16 fills the gap between the lower insulation cover 7 and the upper insulation cover 6, improving the sealing performance between the lower insulation cover 7 and the upper insulation cover 6.

[0032] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
