Description

Technical Field

[0001] This invention relates to the field of conveyor belt technology, specifically to a cold-resistant conveyor belt for product transportation. Background Technology

[0002] The conveyor belt is one of the important components of a belt conveyor. It mainly uses friction to transfer kinetic energy and transport objects. Belt conveyors usually move horizontally to transport materials. In order to further improve the material conveying and transfer rate in the production process, it is usually used in conjunction with an overhead conveyor system to achieve rapid material transfer. The conveyor belt mainly transports materials horizontally to a specific location, and then the overhead conveyor system lifts the materials and transports them to other areas.

[0003] In modern industry and logistics, conveyor belts are indispensable material transport equipment and are widely used in various scenarios. However, in cold-region operations and low-temperature storage environments, the performance of ordinary conveyor belts will significantly decrease due to the effects of low temperatures, posing many challenges to product transportation. Ordinary conveyor belts are usually made of polymer materials such as rubber and plastics. In low-temperature environments, the activity of molecular chain segments in these materials is greatly reduced, and their flexibility weakens, leading to hardening of the conveyor belt. Once the conveyor belt hardens, its bending performance and flexibility deteriorate. During operation, the contact between the conveyor belt and the rollers not only increases the wear of the conveyor belt but also easily causes slippage, reducing conveying efficiency. In severe cases, it can even lead to conveying interruption, affecting the continuity of the entire production process.

[0004] Therefore, we propose a cold-resistant conveyor belt for product transportation. Summary of the Invention

[0011] A fixed plate is attached to the outer surface of the rotating drum and fixed to the inner wall of the preheating frame. A movable plate is slidably connected between the top surface of the fixed plate and the top and bottom surfaces of the base belt. A movable rod is fixed to the outer surface of the movable plate. A reciprocating drive component that cooperates with the rotating sleeve is provided at the end of the movable rod. An automatic opening and closing component that cooperates with the rotating drum is provided at the inner ring of the base belt.

[0012] Preferably, the reciprocating drive includes:

[0013] An incomplete gear is fastened to the outer surface of a rotating sleeve, and a U-shaped rack is slidably connected to the inner wall of the mounting frame, the U-shaped rack meshing with the incomplete gear.

[0015] Preferably, the automatic opening and closing component includes:

[0016] Hollow areas are provided, and multiple hollow areas are evenly arranged in the inner ring of the baseband. The hollow areas are connected to the inner ring surface of the baseband and are provided with extrusion channels. The extrusion channels are provided with sealing blocks. The hollow areas are provided with compression springs that are fixed to the sealing blocks and the inner wall of the hollow areas.

[0017] The elastic partition strips are provided in multiples and are fixed at equal intervals to the inner wall of the hollow area.

[0018] Preferably, the inner wall of the extrusion channel and the outer surfaces of both sides of the sealing block are inclined slopes, and the outer surfaces of both sides of the sealing block away from the compression spring are provided with elliptical air inlet grooves.

[0019] Preferably, the sealing block has a groove on the outer surface of the hollow area, and one end of the compression spring is disposed in the groove.

[0020] Preferably, the temperature equalization mechanism includes:

[0021] A sliding plate is slidably installed on the bottom top surface of the heat-conducting frame. The top surface of the heat-conducting frame has multiple evenly distributed air vents.

[0026] Compared with the prior art, the beneficial effects of the present invention are:

[0027] 1. This invention utilizes the combined action of a preheating mechanism and a temperature equalization mechanism to enable the moving plate on the preheating frame and the sliding plate on the heat conduction frame to reciprocate synchronously. This allows for simultaneous heat conduction treatment of the inner and outer ring surfaces of the baseband at the rotating drum, maintaining a good temperature uniformity between the inner and outer ring surfaces of the baseband. This prevents the baseband from hardening during operation and effectively avoids material aging and performance degradation caused by temperature differences, greatly improving the service life of the baseband.

[0028] 2. The automatic opening and closing component of this invention, through its squeezing action with the rotating drum, can repeatedly open and close the surface of the inner ring of the base belt, thereby creating a closed and heat-insulating environment in the hollow area of ​​the inner ring of the base belt. This further improves the heat insulation performance of the inner ring of the base belt when it is far away from the rotating drum, reduces the cooling rate of the base belt in cold-region operations or low-temperature storage environments, and significantly reduces the possibility of the base belt hardening during operation.

[0040] 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 skilled in the art without creative effort are within the scope of protection of the present invention.

[0041] Please see Figures 1-10 The diagram shows a cold-resistant conveyor belt for transporting products, including a frame 1 and a base belt 2 disposed inside the frame 1. A suspension component for rear suspension movement is provided on one side of the frame 1.

[0042] It should be noted here that after the conveyor belt transports the material to the designated position, the transfer device will accurately transfer the material to the hanger or pod of the intelligent overhead conveyor system, realizing the conversion of material from horizontal conveying to overhead conveying, which facilitates intelligent conveying operation. The transfer device and the intelligent overhead conveyor system are conventional technical components in this application and are existing technologies, so they will not be described in detail here.

[0043] It also includes rotating rollers 3, two of which are rotatably mounted on the inner wall of the frame 1, the base belt 2 is sleeved on the outer surface of the two rotating rollers 3, and a preheating frame 4 fixed to the frame 1 is provided on the inner ring surface of the base belt 2. The preheating frame 4 is provided with a preheating mechanism for heat treatment inside the base belt 2.

[0044] It should be noted that one of the rotating drums 3 is also connected to a drive device for rotating the rotating drum 3, preferably a geared motor. The drive device rotates the rotating drum 3 and the friction between the rotating drum 3 and the base belt 2, thereby enabling the base belt 2 to rotate on the outer surface of the two rotating drums 3. That is, the material is horizontally transported to a specific position through the base belt 2, and then the material is hoisted and transported to other areas through the overhead conveyor system.

[0045] It should also be noted that when the base belt 2 rotates on the surface of the rotating drum 3, a relatively closed internal enclosed area is formed between the preheating frame 4, the frame 1, the rotating drum 3 and the base belt 2. When the base belt 2 runs with the drive device, it drives the preheating mechanism to move synchronously. Thus, the top surface of the inner ring of the base belt 2 is preheated at the front end of the rotating drum 3, thereby preheating the base belt 2 to a certain temperature. This allows the base belt 2 to maintain its elasticity when rotating at the rotating drum 3, effectively preventing the base belt 2 from hardening when rotating and conveying at the rotating drum 3, and improving its bending performance and flexibility.

[0046] The heat-conducting frame 5 is located on the periphery of the rotating drum 3 and is fixed to the inner wall of the frame 1. The heat-conducting frame 5 is equipped with a temperature equalization mechanism that cooperates with the compression heating mechanism.

[0047] It should be noted that the heat-conducting frame 5 forms an external heat-conducting and insulating zone with the side wall of the frame 1 and the outer ring surface of the base belt 2. When the preheating mechanism moves with the drive device, its temperature equalization mechanism also moves accordingly. This allows the outer ring surface of the base belt 2 to be insulated when it reaches the rotating drum 3. Combined with the preheating effect of the preheating mechanism on the inner ring of the base belt 2, and through the heat conduction of the base belt 2 itself and the heat conduction effect of the temperature equalization mechanism, the temperature difference between the inner and outer ring surfaces of the base belt 2 at the rotating drum 3 is kept within a small range, maintaining a stable temperature state. That is, the base belt 2 is in a good temperature equalization environment at the rotating drum 3, further preventing the base belt 2 from hardening during operation. At the same time, it effectively avoids material aging and performance degradation caused by temperature difference, greatly improving the service life of the base belt 2.

[0048] Further as Figure 1 , Figure 2 , Figure 3 , Figure 5 , Figure 6 , Figure 7 , Figure 8 and Figure 10 As shown, it is worth noting that the preheating mechanism includes a mounting frame 6, which is fixed to the outer surface of the frame 1. The inner wall of the mounting frame 6 is provided with a rotating sleeve 7 that is coaxially connected with one of the rotating drums 3. The outer surface of the rotating drum 3 is provided with a plurality of evenly distributed through holes 8. The outer end of the rotating sleeve 7 is fitted with a heating pipe 9 that is fixed to the mounting frame 6.

[0049] A fixed plate 10 is attached to the outer surface of the rotating roller 3 and fixed to the inner wall of the preheating frame 4. A movable plate 11 is slidably connected between the top surface of the fixed plate 10 and the top and bottom surfaces of the base belt 2. A movable rod 12 is fixed to the outer surface of the movable plate 11. A reciprocating drive component that cooperates with the rotating sleeve 7 is provided at the end of the movable rod 12. An automatic opening and closing component that cooperates with the rotating roller 3 is provided at the inner ring of the base belt 2.

[0050] It should be noted that the end of the heating pipe 9 away from the rotating sleeve 7 is connected to the hot air outlet pipe of the hot air blower, which is used to provide hot air to the heating pipe 9. The hot air enters the hollow rotating drum 3 through the rotating sleeve 7, and finally is sent into the closed area of ​​the inner ring of the preheating frame 4, the frame 1, the rotating drum 3 and the base belt 2 through the through hole 8.

[0051] The reciprocating drive component is configured such that when the rotating drum 3 rotates continuously with the drive device, it drives the reciprocating drive component to reciprocate, thereby driving the moving rod 12 and the moving plate 11 to reciprocate between the fixed plate 10 and the inner ring surface of the base belt 2. When the inner ring of the base belt 2 moves to the surface of the rotating drum 3, the automatic opening and closing component squeezes, causing the inner ring surface of the base belt 2 to open. This, combined with the movement of the moving plate 11 driven by the reciprocating drive component, allows the hot air in the closed area of ​​the inner ring to enter the interior of the base belt 2 better, enhancing the heat conduction effect of the base belt 2. At the same time, when the automatic opening and closing component of the base belt 2 moves to the state of separation from the rotating drum 3, the inner ring of the base belt 2 is closed, thus forming a heat preservation treatment at the inner ring of the base belt 2. This effectively improves the internal temperature of the base belt 2 to a suitable level, effectively preventing hardening during operation.

[0052] Further as Figure 1 and Figure 3 As shown, it is worth noting that the reciprocating drive component includes an incomplete gear 13, which is fastened to the outer surface of the rotating sleeve 7. A U-shaped rack rod 14 is slidably connected to the inner wall of the mounting frame 6, and the U-shaped rack rod 14 is meshed with the incomplete gear 13.

[0053] Connecting rod 15, with its two ends fixed to moving rod 12 and U-shaped rack rod 14 respectively;

[0054] It should be noted that the incomplete gear 13 moves synchronously with the rotating drum 3 and the rotating sleeve 7. Due to the meshing of the incomplete gear 13 and the U-shaped rack 14 and the sliding guiding effect of the mounting frame 6 on the U-shaped rack 14, the U-shaped rack 14 can reciprocate on the mounting frame 6, which drives the connecting rod 15 to reciprocate synchronously.

[0055] It should be noted that when the moving rod 12 drives the moving plate 11 to move away from the nearby rotating drum 3, the fixed plate 10 and the preheating frame 4 are in a connected state. That is, hot air will enter between the top surface of the fixed plate 10, the top surface of the inner ring of the base belt 2, and the outer surface of the rotating drum 3. When the moving plate 11 moves in the opposite direction, when the automatic opening and closing component opens the area of ​​the inner ring of the base belt 2, hot air will enter the interior of the base belt 2 by compression. When the base belt 2 moves on the surface of the rotating drum 3, since the inner ring surface of the base belt 2 is in contact with the surface of the rotating drum 3, the hot air that has entered the interior of the base belt 2 is still in the interior space of the base belt 2. When the automatic opening and closing component of the base belt 2 separates from the surface of the rotating drum 3, the interior of the base belt 2 is sealed to store the hot air, thereby forming a heat preservation treatment for the inner ring of the base belt 2. This effectively prevents the base belt 2 from hardening during operation and effectively ensures the service life of the base belt 2 when conveying materials.

[0056] Further as Figure 2 , Figure 3 , Figure 7 , Figure 8 , Figure 9 and Figure 10 As shown, it is worth noting that the automatic opening and closing component includes a hollow area 16. Multiple hollow areas 16 are provided and evenly distributed in the inner ring of the base belt 2. A compression channel 17 is provided in the hollow area 16 and the inner ring surface of the base belt 2. A sealing block 18 is provided in the compression channel 17. A compression spring 19 is provided inside the hollow area 16 and is fixed to the sealing block 18 and the inner wall of the hollow area 16.

[0057] Elastic partition strip 20, multiple elastic partition strips are provided and the multiple partition strips are fixed at equal intervals to the inner wall of the hollow area 16;

[0058] It should be noted that the baseband 2 can be formed by pressing a double-layer structure consisting of an outer ring and an inner ring. The inner ring of the baseband 2 has a rubber pad as its base and a hollow area 16 is formed in the middle. Then, by setting an elastic partition strip 20 in the hollow area 16, the hollow area 16 is divided into several small intervals. While the elastic partition strip 20 ensures the strength and toughness of the inner ring of the baseband 2, a hollow heat insulation space is formed.

[0059] The outer ring of the base strip 2 can be vulcanized at low temperature for a long time, which can help reduce stress concentration inside the rubber of the outer ring of the base strip 2 and reduce the possibility of cracking in low temperature environment. In addition, cold-resistant plasticizers can be added to the outer ring of the base strip 2 to further improve the cold resistance of the base strip 2.

[0060] It should be noted that after the inner and outer rings of the baseband 2 are pressed and formed, the sealing block 18 forms an elastic seal on the extrusion channel 17 due to the elastic force of the compression spring 19. When the baseband 2 rotates with the rotating roller 3, when the bottom of the sealing block 18 contacts the rotating roller 3, the compression of the sealing block 18 by the surface of the rotating roller 3 can compress the compression spring 19, causing the sealing block 18 to move toward the hollow area 16 of the inner ring of the baseband 2. At this time, the sealing block 18 opens the extrusion channel 17. With the drive of the reciprocating drive and the reciprocating compression of the moving plate 11, the hollow area 16 is instantly filled with hot air, which effectively improves the heat conduction performance of the baseband 2, avoids the hardening phenomenon of the baseband 2, and ensures its service life.

[0061] When the sealing block 18 moves with the base belt 2, the sealing block 18 separates from the surface of the rotating roller 3. At this time, the sealing block 18 seals the extrusion channel 17 through the elastic force of the compression spring 19, which forms the heat preservation treatment of the hollow area 16 of the base belt 2, effectively reducing the cooling rate of the base belt 2 in cold operation or low temperature storage environment.

[0062] Further as Figure 6 , Figure 7 , Figure 8 and Figure 10 As shown, it is worth noting that the inner wall of the extrusion channel 17 and the outer surfaces of both sides of the sealing block 18 are both inclined slopes. Through the elastic force of multiple compression springs 19, the slope setting can effectively improve the relative sealing effect of the sealing block 18 on the extrusion channel 17. The outer surfaces of the sealing block 18 away from the compression springs 19 are provided with elliptical air inlet grooves. When the rotating roller 3 extrudes the sealing block 18, the elliptical air inlet grooves effectively improve the opening state of the sealing block 18 on the extrusion channel 17, so that the hollow area 16 can be quickly filled with heat.

[0063] Further as Figure 7 As shown, it is worth noting that the sealing block 18 has a groove on the outer surface of the hollow area 16, and one end of the compression spring 19 is located in the groove. When the compression spring 19 is compressed, the groove can guide and limit the compression spring 19 to a certain extent, thus preventing the sealing block 18 from shifting.

[0064] Further as Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 8 , Figure 9 and Figure 10 As shown, it is worth noting that the temperature equalization mechanism includes a sliding plate 21, which is slidably mounted on the bottom top surface of the heat conduction frame 5. The top surface of the heat conduction frame 5 has multiple evenly distributed air outlets 22. One end of the sliding plate 21 is fixed with a push rod 23, and a fixing frame 24 is fixed between the push rod 23 and the U-shaped rack rod 14.

[0065] Branch pipe 25 is located outside the sliding plate 21 and is connected to the outer surface of the heat-conducting frame 5. The other end of the branch pipe 25 passes through the mounting frame 6 and is connected to the bottom surface of the heating pipe 9.

[0066] It should be noted that the heat-conducting frame 5 and the outer ring of the baseband 2 are heated through the branch pipe 25. At this time, the fixed frame 24, the push rod 23 and the sliding plate 21 are moved by the reciprocating drive component. This allows the sliding plate 21 to move on the bottom and top surface of the heat-conducting frame 5. When the sliding plate 21 moves away from the fixed frame 24, it drives the hot air sent in through the branch pipe 25 to be squeezed out, so that the hot air flows out from the air outlet 22. This can not only conduct heat to the surface of the outer ring of the baseband 2 at the heat-conducting frame 5, but also blow air to clean the surface of the outer ring of the baseband 2 above the heat-conducting frame 5, effectively improving the cleaning effect of the surface of the outer ring of the baseband 2.

[0067] Further as Figure 5 , Figure 7 and Figure 9 As shown, it is worth noting that the contact surface between the heat-conducting frame 5 and the outer ring of the baseband 2 is a matching arc surface, which can scrape the surface of the outer ring of the baseband 2 to a certain extent. Combined with the squeezing and blowing formed by the reciprocating motion of the sliding plate 21, the cleaning effect of the outer ring surface of the baseband 2 is further improved. The top surface of the heat-conducting frame 5 is set with an inclined slope, which is conducive to the better falling off of the scraped or blown impurities.

[0068] Further as Figure 1 , Figure 2 , Figure 9 and Figure 10 As shown, it is worth noting that a wiping rod 26 is rotatably connected to the outer surface of the fixed frame 24 away from the sliding plate 21. The wiping rod 26 is tangential to the outer ring surface of the base belt 2. The wiping rod 26 is positioned so that it reciprocates with the reciprocating drive component, thereby driving the wiping rod 26 to perform reciprocating rolling processing, thus providing better cleaning of the bottom surface of the outer ring of the base belt 2 during operation.

[0069] Further as Figure 1 , Figure 2 , Figure 5 and Figure 9 As shown, it is worth noting that limit strips 27 are provided above both ends of the two heat-conducting frames 5. The two limit strips 27 are fixed to the top inner wall of the frame 1 respectively. The bottom surface of the limit strips 27 is attached to the top surface of the outer ring of the base belt 2. The setting of the limit strips 27, together with the heat-conducting frames 5, guides and limits the top surface of the outer ring of the base belt 2, and guides and limits the inner ring surface of the base belt 2 through the preheating frame 4 and the rotating roller 3, thereby effectively improving the stability of the base belt 2 during operation.

[0070] This solution has the following working process: Driven by the drive device, the base belt 2 moves on the frame 1 through friction with the rotating drum 3, thus conveying the material on the top surface of the outer ring of the base belt 2 to the front end of the subsequent overhead conveyor system. Through the cooperation of the preheating mechanism and the temperature equalization mechanism, that is, through the cooperation of the rotating drum 3 and the reciprocating drive component, the moving plate 11 on the preheating frame 4 and the sliding plate 21 on the heat conduction frame 5 move back and forth synchronously. This allows for simultaneous heat conduction treatment of the inner and outer ring surfaces of the base belt 2 at the rotating drum 3, ensuring that the inner and outer ring surfaces of the base belt 2 maintain a good temperature uniformity. This prevents the base belt 2 from hardening during operation and effectively avoids material aging and performance degradation caused by temperature differences, greatly improving the service life of the base belt 2.

[0071] The automatic opening and closing mechanism, through its squeezing action with the rotating drum 3, can repeatedly open and close the inner ring surface of the base belt 2, thereby creating a closed and insulated environment in the hollow area 16 of the inner ring of the base belt 2. This further improves the insulation performance of the inner ring of the base belt 2 when it is far away from the rotating drum 3, reduces the cooling rate of the base belt 2 in cold operation or low-temperature storage environments, and significantly reduces the possibility of the base belt 2 hardening during operation.
