Description

Technical Field

[0001] This application relates to the technical field of rubber product manufacturing equipment, and in particular to a spatially compact multi-layer automatic cooling device for continuous production of rubber materials. Background Technology

[0002] Rubber is an indispensable material in modern industry, widely used in automobiles, construction, electronics, medical and other fields. With the advancement of technology and the continuous growth of market demand, the efficiency and quality requirements of rubber production are also increasing. In the production process of rubber products (such as sealing strips, conveyor belts, tire parts), the materials are usually in a high-temperature state (e.g., 80°C-150°C) after mixing, extrusion or calendering, and must be cooled to near room temperature before cutting, winding or further processing.

[0003] Currently, factories generally use two cooling methods. One is a long-distance single-layer cooling line, where materials slowly pass through a cooling water tank or suspended air-cooling line that is tens of meters long. This method occupies a huge area, and the cooling efficiency is limited by the effective heat dissipation length. In addition, the utilization rate of factory space is low. The other method is a multi-layer immersion water tank. Although it saves floor space, it has many drawbacks, such as high resource and energy consumption, easy contamination of water quality by rubber materials (especially those containing certain additives) or surface impact by water quality, the need for subsequent drying and dehydration, increased processes and energy consumption, and unsuitability for certain processes (such as when the surface needs to remain tacky). Summary of the Invention

[0004] To address the issue of low heat dissipation efficiency in rubber products, this application provides a space-intensive multi-layer automatic cooling device for continuous production of rubber materials.

[0005] This application provides a spatially compact, multi-layer automatic cooling device for continuous rubber material production, employing the following technical solution: A space-intensive multi-layer automatic cooling device for continuous rubber material production includes a movable frame comprising several mounting frames. A horizontally arranged conveyor belt is mounted on the top surface of each mounting frame. The conveying directions of adjacent conveyor belts are opposite. The discharge end of each conveyor belt is located above the next layer of conveyor belt. A feeding plate is mounted at the inlet end of the topmost conveyor belt, and a discharge plate is mounted at the outlet end of the bottommost conveyor belt. Several axial flow fans are mounted at the top of the movable frame, spaced apart along the length of the conveyor belts, and located above the topmost conveyor belt. Several air coolers are mounted on the sides of the movable frame, spaced apart vertically.

[0006] By adopting the above technical solution, the high-temperature rubber material is first conveyed to the top conveyor belt via a feeding plate and then transported forward. Cool air from an axial fan blows directly onto the surface of the high-temperature rubber material from top to bottom, providing the most effective initial rapid cooling. After reaching the end of the top conveyor belt, the high-temperature rubber material, having lost its support, falls freely under its own gravity to the next conveyor belt and continues to be transported in the opposite direction. Simultaneously, the cool air from the air conditioner continues to cool the high-temperature rubber material. Direct contact between the high-temperature rubber material and the cooled conveyor belt also facilitates heat transfer. This process is repeated layer by layer, with the rubber material moving along a continuous... The material continues its downward zigzag path until it is output from the bottom conveyor belt to the discharge plate, thus completing the cooling of the high-temperature rubber material. Through the vertical multi-layer zigzag material flow channel design, the traditional horizontal cooling line of tens of meters long is integrated into a vertical space, reducing the floor space by more than 70%. It is particularly suitable for the renovation of space-constrained factories or the construction of new compact production lines. The combination of top strong wind initial cooling and multi-layer contact cooling allows the material to achieve double-sided heat dissipation (convection on the upper surface and conduction on the lower surface) on each layer, and to receive brief natural heat dissipation during the descent. The total heat exchange area is much larger than that of single-layer cooling, achieving rapid and uniform cooling.

[0007] Preferably, the top surface of the mounting frame is fixed with two fixed plates and two adjusting plates. A drive roller is rotatably mounted between the two fixed plates, and a driven roller is rotatably mounted between the two adjusting plates. The drive roller and the driven roller are arranged vertically in an alternating manner. The conveyor belt is wound around the outer periphery of the drive roller and the driven roller. The moving frame is provided with a drive component for driving the drive roller to rotate.

[0008] By adopting the above technical solution, the driving component drives the active roller to rotate, and the active roller drives the conveyor belt to move, thereby conveying the high-temperature rubber material.

[0009] Preferably, the driving component includes two motors and several chains. The output end of each motor is coaxially fixed with a drive gear, and the end of the driving roller is coaxially fixed with a driven gear one and a driven gear two. The several chains include a drive chain and a transmission chain. The drive chain is wound around the outer periphery of the drive gear and the adjacent driven gear one, and the transmission chain is wound around the outer periphery of the driven gear one and the adjacent driven gear two.

[0010] By adopting the above technical solution, the motor drives the drive gear to rotate, the drive gear drives the adjacent driven gear one to rotate through the drive chain, the driven gear one drives the coaxial drive roller and driven gear two to rotate, the driven gear two drives the adjacent driven gear one to rotate through the transmission chain, the driven gear one then drives the coaxial drive roller and driven gear two to rotate, thereby driving several drive rollers in the same column to rotate in the same direction, thus making the conveying directions of two adjacent conveyor belts opposite.

[0011] Preferably, the movable frame is equipped with a plurality of tension gears, each of which corresponds to a transmission chain, and the transmission chain meshes with the corresponding tension gear.

[0012] By adopting the above technical solution, the transmission chain is tensioned using a tensioning gear to compensate for chain wear and maintain stable chain transmission.

[0013] Preferably, the adjusting plate is located at the feed end of the conveyor belt, and a horizontally arranged adjusting groove is provided on the side of the adjusting plate. The adjusting block slides and engages with the adjusting plate along the length direction of the conveyor belt through the adjusting groove. Adjusting blocks are rotatably installed at both ends of the driven roller, and adjusting screws are rotatably installed on the side of the adjusting blocks. A threaded hole communicating with the adjusting groove is provided on the side of the adjusting plate, and the adjusting screw is threadedly connected to the adjusting plate through the threaded hole. A tensioning member for tensioning the conveyor belt is provided on the mounting frame.

[0014] By adopting the above technical solution, rotating the adjusting screw causes the adjusting block to move horizontally within the adjusting groove, thereby adjusting the position of the feed end of the conveyor belt. This allows even larger high-temperature rubber materials to fall smoothly onto the top of the conveyor belt, ensuring the smooth transport of the high-temperature rubber materials on the conveyor belt.

[0015] Preferably, two control plates are mounted on the top surface of the mounting frame, and sliding grooves are respectively opened on the opposite inner sides of the two control plates. The control plates are mounted with sliders that slide vertically through the sliding grooves. The tensioning member includes a tensioning roller rotatably mounted between the two sliders, and the outer peripheral surface of the tensioning roller can abut against the outer peripheral surface of the adjacent conveyor belt.

[0016] By adopting the above technical solution and controlling the height of the tension roller, the tension roller is made to fit tightly against the outer circumference of the conveyor belt, preventing the conveyor belt from sagging excessively due to the weight of the material and its own tension, thus ensuring smooth material conveying.

[0017] Preferably, the control plate has a feed slot on its side that communicates with the slide groove, a positioning screw is inserted in the feed slot, the positioning screw is threadedly connected to the slider, and the nut of the positioning screw can abut against the side of the control plate.

[0018] By adopting the above technical solution, after adjusting the height of the tension roller, the positioning screw is rotated so that the nut of the positioning screw can abut against the side of the control plate, thereby fixing the height of the tension roller.

[0019] Preferably, a vertically arranged control screw is rotatably mounted on the inner bottom surface of the slide groove. A guide block is sleeved on the outer periphery of the control screw, and the guide block is threadedly engaged with the control screw. A guide sleeve is sleeved on the outer periphery of the guide block, and the guide sleeve slides vertically with the control plate through the slide groove. A spring is fixed on the top surface of the guide block, and the top end of the spring is fixedly connected to the inner top surface of the guide sleeve. The top surface of the guide sleeve can abut against the bottom surface of the slider.

[0020] By adopting the above technical solution, the positioning screw is first loosened, and then the control screw is rotated. The control screw pushes the guide block upward, so that the top surface of the guide sleeve abuts against the bottom surface of the slider. Then, the guide block is moved upward, and the guide block compresses the spring, which increases the elastic force of the spring. When the operator adjusts the position of the feed end of the conveyor belt, the conveyor belt may become loose. Under the action of the spring, the tension roller always keeps in close contact with the conveyor belt, thereby ensuring that the conveyor belt remains taut during the adjustment process.

[0021] Preferably, a worm gear is fixedly sleeved on the outer periphery of the control screw, a worm is rotatably mounted between the two control plates, the worm meshes with the worm gear, and a knob is fixed to one end of the worm.

[0022] By adopting the above technical solution, rotating the knob drives the worm gear to rotate, which in turn drives two worm wheels to rotate synchronously. The worm wheels then drive the control screw to rotate, thereby adjusting the position of the guide block and thus controlling the degree of spring compression.

[0023] Preferably, the conveyor belt is a mesh-like rigid rubber layer.

[0024] By adopting the above technical solution, the mesh structure of the conveyor belt increases the contact area between the rubber material, the cooling air, and the conveyor belt, providing good air permeability, which is conducive to the penetration of cold air and enhances convective heat transfer. In addition, the rigidity of the conveyor belt ensures the flatness of the support.

[0025] In summary, this application includes at least one of the following beneficial technical effects: The high-temperature rubber material is first conveyed to the top conveyor belt via a feeding plate and then carried forward. The cold air output by the axial fan blows directly onto the surface of the high-temperature rubber material from top to bottom, achieving the most effective initial rapid cooling. After the high-temperature rubber material is conveyed to the end of the top conveyor belt, it falls freely to the next layer of conveyor belt under its own gravity due to the loss of support, and then turns to the opposite direction to continue being conveyed. At the same time, the cold air output by the air cooler continues to cool the high-temperature rubber material. The direct contact between the high-temperature rubber material and the cooled conveyor belt also enables heat transfer. This process is repeated layer by layer. The rubber material descends along a continuous zigzag path on the moving frame until it is output from the bottom conveyor belt to the discharge plate, thus completing the cooling of the high-temperature rubber material. Through the vertical multi-layer "zigzag" material flow channel design, the traditional horizontal cooling line that is tens of meters long is integrated into a vertical space, reducing the floor space by more than 70%, which is particularly suitable for the renovation of space-constrained factories or the construction of new compact production lines. By combining top-mounted strong airflow initial cooling with multi-layer contact cooling, the material can achieve double-sided heat dissipation (convection on the upper surface and conduction on the lower surface) in each layer, and receive brief natural heat dissipation during the fall. The total heat exchange area is much larger than that of single-layer cooling, achieving rapid and uniform cooling. Attached Figure Description

[0032] The following is in conjunction with the appendix Figure 1-5 This application will be described in further detail.

[0033] This application discloses a spatially compact multi-layer automatic cooling device for continuous production of rubber materials.

[0034] Reference Figure 1 and Figure 2 A space-intensive, multi-layered automatic cooling device for continuous rubber production includes a movable frame 1 with several casters 16 mounted on its bottom. The movable frame 1 comprises five vertically spaced mounting frames 11, with a horizontally arranged conveyor belt 2 on the top surface of each frame 11. The conveyor belt 2 is a mesh-like rigid rubber layer. The mesh structure of the conveyor belt 2 increases the contact area between the rubber material, cooling air, and the conveyor belt 2, providing good air permeability, facilitating cold air penetration, enhancing convective heat transfer, and ensuring flat support due to the rigid nature of the conveyor belt 2.

[0035] Reference Figure 1 The conveying directions of two adjacent conveyor belts 2 are opposite, and the discharge end of conveyor belt 2 is located above the next layer of conveyor belt 2. The top layer of conveyor belt 2 has a feeding plate 12 at its inlet, and the bottom layer of conveyor belt 2 has a discharge plate 13 at its outlet. Several axial flow fans 14 are installed at the top of the moving frame 1, spaced apart along the length of the conveyor belt 2, and located above the top layer of conveyor belt 2. Several air coolers 15 are installed on the sides of the moving frame 1, spaced apart vertically.

[0036] The high-temperature rubber material is first conveyed to the top conveyor belt 2 via the feeding plate 12 and then conveyed forward. The cold air output by the axial fan 14 blows directly onto the surface of the high-temperature rubber material from top to bottom, achieving the most effective initial rapid cooling. After the high-temperature rubber material is conveyed to the end of the top conveyor belt 2, it falls freely to the next layer conveyor belt 2 under its own gravity due to the loss of support, and then turns to the opposite direction to continue conveying. At the same time, the cold air output by the air cooler 15 continues to cool the high-temperature rubber material. This process is repeated layer by layer. The high-temperature rubber material descends along a continuous zigzag path on the moving frame 1 until it is output from the bottom conveyor belt 2 to the discharge plate 13, thus completing the cooling of the high-temperature rubber material.

[0037] Reference Figure 3 and Figure 4 The top surface of the mounting frame 11 is fixed with two fixed plates 21 and two adjusting plates 23. A drive roller 22 is rotatably mounted between the two fixed plates 21, and a driven roller 24 is rotatably mounted between the two adjusting plates 23. The drive roller 22 and the driven roller 24 are arranged vertically in an alternating pattern, and the conveyor belt 2 is wound around the outer periphery of the drive roller 22 and the driven roller 24. Two motors 25 and several chains 26 are mounted on the moving frame 1. A drive gear 251 is coaxially fixed to the output end of the motor 25. A driven gear 1 221 and a driven gear 222 are coaxially fixed to the end of the drive roller 22. The several chains 26 include a drive chain 261 and a transmission chain 262. The drive chain 261 is wound around the outer periphery of the drive gear 251 and the adjacent driven gear 1 221, and the transmission chain 262 is wound around the outer periphery of the driven gear 1 221 and the adjacent driven gear 222. Several tension gears 27 are installed on the movable frame 1. Each tension gear 27 corresponds to a transmission chain 262, and the transmission chain 262 meshes with the corresponding tension gear 27. The tension gears 27 are used to tension the transmission chain 262 to compensate for chain wear and maintain stable chain transmission.

[0038] Motor 25 drives drive gear 251 to rotate. Drive gear 251 drives adjacent driven gear 1 221 to rotate via drive chain 261. Driven gear 1 221 drives coaxial drive roller 22 and driven gear 222 to rotate. Driven gear 222 drives adjacent driven gear 1 221 to rotate via transmission chain 262. Driven gear 1 221 then drives coaxial drive roller 22 and driven gear 222 to rotate, thereby driving several drive rollers 22 in the same column to rotate in the same direction, thus making the conveying directions of two adjacent conveyor belts 2 opposite.

[0039] Reference Figure 3The adjusting plate 23 is located at the feed end of the conveyor belt 2, and a horizontally arranged adjusting groove 231 is provided on the side of the adjusting plate 23. Adjusting blocks 241 are rotatably installed at both ends of the driven roller 24, and the adjusting blocks 241 slide and engage with the adjusting plate 23 along the length direction of the conveyor belt 2 through the adjusting groove 231. An adjusting screw 232 is rotatably installed on the side of the adjusting block 241, and a threaded hole 233 communicating with the adjusting groove 231 is provided on the side of the adjusting plate 23. The adjusting screw 232 is threadedly connected to the adjusting plate 23 through the threaded hole 233.

[0040] Rotating the adjusting screw 232 causes the adjusting block 241 to move horizontally within the adjusting groove 231, thereby adjusting the position of the feed end of the conveyor belt 2. This allows larger high-temperature rubber materials to fall smoothly onto the top of the conveyor belt 2, ensuring the smooth transport of the high-temperature rubber materials on the conveyor belt 2.

[0041] Reference Figure 1 and Figure 5 Two control plates 3 are mounted on the top surface of the mounting frame 11. Slide grooves 31 are respectively formed on the inner sides of the two control plates 3, and sliders 32 are mounted on the control plates 3 by sliding vertically through the slide grooves 31. A tension roller 33 is rotatably mounted between the two sliders 32, and the outer circumferential surface of the tension roller 33 can abut against the outer circumferential surface of the adjacent conveyor belt 2. By controlling the height of the tension roller 33, it is ensured that the tension roller 33 is in close contact with the outer circumferential surface of the conveyor belt 2, preventing the conveyor belt 2 from sagging excessively due to the weight of the material and its own tension, thus ensuring smooth material conveying.

[0042] Reference Figure 1 and Figure 5 The control plate 3 has a feed groove 34 on its side that communicates with the slide groove 31, and a positioning screw 35 passes through the feed groove 34. The positioning screw 35 is threadedly connected to the slider 32, and the nut of the positioning screw 35 can abut against the side of the control plate 3. After adjusting the height of the tension roller 33, the positioning screw 35 is rotated so that the nut of the positioning screw 35 can abut against the side of the control plate 3, thereby fixing the height of the tension roller 33.

[0043] Reference Figure 1 and Figure 5A vertically mounted control screw 41 is rotatably mounted on the inner bottom surface of the slide groove 31. A guide block 42 is sleeved on the outer periphery of the control screw 41, and the guide block 42 is threadedly engaged with the control screw 41. A guide sleeve 4 is sleeved on the outer periphery of the guide block 42, and the guide sleeve 4 slides vertically with the control piece 3 through the slide groove 31. The top surface of the guide sleeve 4 can abut against the bottom surface of the slider 32. A spring 43 is fixed on the top surface of the guide block 42, and the top end of the spring 43 is fixedly connected to the inner top surface of the guide sleeve 4. A worm gear 44 is fixedly sleeved on the outer periphery of the control screw 41. A worm 45 is rotatably mounted between the two control pieces 3, and the worm 45 meshes with the worm gear 44. A knob 46 is fixed to one end of the worm 45.

[0044] First, loosen the positioning screw 35 and rotate the knob 46. The knob 46 drives the worm gear 45 to rotate, which in turn drives the two worm wheels 44 to rotate synchronously. The worm wheels 44 drive the control screw 41 to rotate, which in turn pushes the guide block 42 upward, so that the top surface of the guide sleeve 4 abuts against the bottom surface of the slider 32. Then, continue to move the guide block 42 upward, which compresses the spring 43, increasing the elasticity of the spring 43. When the operator adjusts the position of the feed end of the conveyor belt 2, the conveyor belt 2 may become loose. Under the elasticity of the spring 43, the tension roller 33 always keeps in close contact with the conveyor belt 2, thus ensuring that the conveyor belt 2 remains taut during the adjustment process.

[0045] The implementation principle of a space-intensive multi-layer automatic cooling device for continuous production of rubber materials according to an embodiment of this application is as follows: The high-temperature rubber material is first conveyed to the top conveyor belt 2 through the feeding plate 12 and is conveyed forward along it. The cold air output by the axial fan 14 blows directly from top to bottom onto the surface of the high-temperature rubber material for the most effective initial rapid cooling. After the high-temperature rubber material is conveyed to the end of the top conveyor belt 2, it falls freely to the next layer conveyor belt 2 under its own gravity due to the loss of support, and turns to the opposite direction to continue conveying. At the same time, the cold air output by the air cooler 15 continues to cool the high-temperature rubber material. This process is repeated layer by layer. The rubber material goes down along a continuous zigzag path on the moving frame 1 until it is output from the bottom conveyor belt 2 to the discharge plate 13, thereby completing the cooling of the high-temperature rubber material.

[0046] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
