Description

Technical Field

[0001] The present invention relates to the technical field of conveyor belts, and particularly to a conveyor belt with cold resistance performance for product transportation. Background Art

[0002] The conveyor belt is one of the important accessories in the belt conveyor. It mainly realizes kinetic energy transfer and object transportation through friction. The belt conveyor usually moves horizontally to transport materials. In order to further improve the conveying and transfer rate of materials during the production process, it usually cooperates with a hanging conveying system to achieve rapid transfer of materials. It mainly horizontally transports materials through the conveyor belt to a specific position, and then the hanging conveying system lifts and transports the materials to other areas.

[0003] In the fields of modern industry and logistics transportation, the conveyor belt, as an indispensable material transportation equipment, is widely used in various scenarios. However, in cold region operations and low-temperature storage environments, due to the influence of the low-temperature environment, the performance of ordinary conveyor belts will significantly decline, bringing many challenges to product transportation. Ordinary conveyor belts are usually made of polymer materials such as rubber and plastic. In a low-temperature environment, the activity of the molecular chain segments of these materials is greatly reduced, and the flexibility weakens, resulting in the hardening of the conveyor belt. Once the conveyor belt hardens, its bending performance and flexibility become poor. During operation, the conveyor belt and the roller not only increase the wear of the conveyor belt, but also are prone to slipping, reducing the conveying efficiency. In severe cases, it may even lead to the interruption of conveying, affecting the continuity of the entire production process.

[0004] Therefore, we propose a conveyor belt with cold resistance performance for product transportation. Summary of the Invention

Detailed implementation manners

[0040] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0041] Please refer to Figures 1 - 10 , a conveyor belt with cold resistance performance for product transportation in the illustration, including a frame 1 and a base belt 2 arranged inside the frame 1, and a hanging component for hanging and moving after transportation is arranged on one side of the frame 1;

[0042] It should be noted here that: after the conveyor belt transports the materials to the designated position, the transfer device will accurately transfer the materials to the hangers or pods of the intelligent suspended conveyor system, realizing the conversion of the materials from horizontal transportation to suspended transportation, facilitating the auxiliary intelligent transportation operation. The transfer device and the intelligent suspended conveyor system are conventional technical components in this application and are not elaborated here as they are part of the prior art;

[0043] It further includes rotating drums 3. There are two rotating drums 3, and both are rotatably installed on the inner wall of the frame 1. The base belt 2 is sleeved on the outer surfaces of the two rotating drums 3. A preheating frame 4 fixed to the frame 1 is provided on the inner ring surface of the base belt 2. A preheating mechanism for heating the inside of the base belt 2 is provided inside the preheating frame 4;

[0044] It should be noted that a driving device for rotating the rotating drum 3 is also connected to one of the rotating drums 3. Preferably, it is a reduction motor. By driving the rotation of the rotating drum 3 and the frictional force between the rotating drum 3 and the base belt 2, the base belt 2 is rotated on the outer surfaces of the two rotating drums 3, that is, the materials are horizontally transported to a specific position through the base belt 2, and then the materials are hoisted and transported to other areas through the suspended conveyor system;

[0045] It also should be noted that when the base belt 2 rotates on the surface of the rotating drum 3, a relatively closed internal closed area is formed among the preheating frame 4, the frame 1, the rotating drum 3, and the base belt 2. When the base belt 2 operates with the driving device, it drives the preheating mechanism to move synchronously. Thus, the top surface of the inner ring of the base belt 2 is preheated when it reaches the front end of the rotating drum 3, so that the base belt 2 is preheated to a certain temperature, enabling the base belt 2 to maintain its elasticity when rotating at the rotating drum 3, effectively avoiding the hardening phenomenon of the base belt 2 when rotating and transporting at the rotating drum 3, and improving its bending performance and flexibility;

[0046] A heat conduction frame 5 is provided on the periphery of the rotating drum 3 and is fixed to the inner wall of the frame 1. A temperature equalizing mechanism cooperating with the compressed heating mechanism is provided inside the heat conduction frame 5;

[0047] It should be noted that the heat-conducting frame 5 forms an external heat-insulating and heat-conducting interval with the side wall of the frame 1 and the outer ring surface of the baseband 2. When the preheating mechanism moves along with the driving device, the temperature equalizing mechanism also moves accordingly. As a result, when the baseband 2 rotates to the rotating drum 3, heat preservation treatment is carried out on the outer ring surface of the baseband 2 at this position. In cooperation with the preheating effect of the preheating mechanism on the inner ring of the baseband 2, through the heat conduction effect of the baseband 2 itself and the heat conduction effect of the temperature equalizing mechanism, the temperature difference between the inner and outer ring surfaces of the baseband 2 at the rotating drum 3 is maintained within a small range, keeping it in a stable temperature state, that is, the baseband 2 has a good temperature equalizing environment at the rotating drum 3, further avoiding the hardening phenomenon of the baseband 2 during operation, and effectively avoiding material aging and performance deterioration caused by temperature difference, greatly improving the service life of the baseband 2.

[0048] Furthermore, as Figure 1 , Figure 2 , Figure 3 , Figure 5 , Figure 6 , Figure 7 , Figure 8 and Figure 10 shown, specifically, the preheating mechanism includes a mounting frame 6, the mounting frame 6 is fixed on the outer surface of the frame 1, a rotating sleeve 7 coaxially connected with one of the rotating drums 3 is arranged on the inner wall of the mounting frame 6, a plurality of through holes 8 evenly distributed are formed on the outer surface of the rotating drum 3, and a heating pipe 9 fixed to the mounting frame 6 is sleeved on the outer end of the rotating sleeve 7;

[0049] A fixing plate 10, the fixing plate 10 is attached to the outer surface of the rotating drum 3 and fixed to the inner wall of the preheating frame 4. A moving plate 11 is slidably connected between the top surface of the fixing plate 10 and the bottom surface of the top of the baseband 2. A moving rod 12 is fixed to the outer surface of the moving plate 11, a reciprocating driving member cooperating with the rotating sleeve 7 is arranged at the end of the moving rod 12, and an automatic opening and closing member cooperating with the rotating drum 3 is arranged at the inner ring of the baseband 2;

[0050] It should be noted that one end of the heating pipe 9 away from the rotating sleeve 7 is externally connected to the air outlet pipe of a hot air blower, so as to supply hot air to the heating pipe 9, and the hot air enters the hollow rotating drum 3 through the rotating sleeve 7, and finally the hot air is sent into the closed interval of the preheating frame 4, the frame 1, the rotating drum 3 and the inner ring of the baseband 2 through the through holes 8;

[0051] The reciprocating driving member is arranged such that when the rotating drum 3 rotates continuously with the driving device, it drives the reciprocating driving member to perform reciprocating motion, thereby driving the moving rod 12 and the moving plate 11 to perform reciprocating motion at the inner ring surface of the fixing plate 10 and 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 member squeezes, causing the inner ring surface of the base belt 2 to be in an open state. Cooperating with the reciprocating driving member to drive the moving plate 11 to move, so that the hot air in the closed interval at the inner ring can better enter the inside of the base belt 2, strengthening the heat conduction effect of the base belt 2. At the same time, when the automatic opening and closing member of the base belt 2 moves to a separated state from the rotating drum 3, the inner ring of the base belt 2 is in a closed state at this time, so that heat preservation treatment can be formed at the inner ring of the base belt 2, effectively improving the internal temperature of the base belt 2 to be suitable, and effectively avoiding hardening during its operation.

[0052] Further, as Figure 1 and Figure 3 shown, specifically, the reciprocating driving member includes an incomplete gear 13, the incomplete gear 13 is tightly sleeved on the outer surface of the rotating sleeve 7, and a U-shaped rack bar 14 is slidably connected to the inner wall of the mounting frame 6, and the U-shaped rack bar 14 is meshed with the incomplete gear 13;

[0053] The connecting rod 15, the two ends of the connecting rod 15 are respectively fixed to the moving rod 12 and the U-shaped rack bar 14;

[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 action between the incomplete gear 13 and the U-shaped rack bar 14 and the sliding guiding action of the mounting frame 6 on the U-shaped rack frame, the U-shaped rack frame can reciprocate on the mounting frame 6, that is, drive the connecting rod 15 to perform synchronous reciprocating motion;

[0055] It should be noted that when the moving rod 12 drives the moving plate 11 to move away from the adjacent rotating drum 3, the fixing plate 10 and the preheating frame 4 are in a communicating state at this time, that is, hot air will enter between the top surface of the fixing 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 reverse direction later, when the automatic opening and closing member opens the area at the inner ring of the base belt 2, hot air will enter the inside of the base belt 2 by extrusion. 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 entering the inside of the base belt 2 is still in the internal space of the base belt 2. When the automatic opening and closing member of the base belt 2 is separated from the surface of the rotating drum 3, the inside of the base belt 2 forms a closed treatment at this time, storing the hot air, so as to form heat preservation treatment for the inner ring of the base belt 2, effectively avoiding hardening during the operation of the base belt 2, and effectively ensuring the service life of the base belt 2 when conveying materials.

[0056] Further, as shown in Figure 2 , Figure 3 , Figure 7 , Figure 8 , Figure 9 and Figure 10 it is worth specifically explaining that the automatic opening and closing member includes a hollow area 16. A plurality of hollow areas 16 are provided and are evenly arranged at the inner ring of the base belt 2. An extrusion channel 17 is communicated with the inner ring surface of the base belt 2. A blocking block 18 is arranged in the extrusion channel 17. A compression spring 19 that is fixed to the blocking block 18 and the inner wall of the hollow area 16 is arranged inside the hollow area 16;

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

[0058] It should be noted that the base belt 2 can be formed by a double-layer structure of the outer ring of the base belt 2 and the inner ring of the base belt 2 through pressing. The inner ring of the base belt 2 is based on a rubber cushion layer, and a hollow area 16 is formed in the middle. Subsequently, by arranging elastic partition strips 20 in the hollow area 16, several small intervals are formed in the hollow area 16. Under the condition that the elastic partition strips 20 ensure the use strength and toughness at the inner ring of the base belt 2, a hollow heat insulation space is formed;

[0059] The outer ring of the base belt 2 can adopt a low-temperature long-time vulcanization process, which can not only help reduce the stress concentration inside the rubber of the outer ring of the base belt 2, but also reduce the possibility of cracks appearing in a low-temperature environment. In addition, a cold-resistant plasticizer can be added to the outer ring of the base belt 2 to further improve the cold-resistant performance of the base belt 2;

[0060] It should be noted that after the inner ring and the outer ring of the base belt 2 are press-molded, due to the elastic force of the compression spring 19, the blocking block 18 elastically blocks the extrusion channel 17. When the base belt 2 rotates with the rotation of the rotating drum 3, when the bottom of the blocking block 18 comes into contact with the rotating drum 3, at this time, through the extrusion of the surface of the rotating drum 3 on the blocking block 18, the compression spring 19 can be compressed, so that the blocking block 18 moves towards the hollow area 16 of the inner ring of the base belt 2. At this time, the blocking block 18 opens the extrusion channel 17. With the driving of the reciprocating driving member and the reciprocating compression of the moving plate 11, the hollow area 16 is instantaneously filled with hot air, effectively improving the heat conduction performance of the base belt 2, avoiding the hardening phenomenon of the base belt 2, and ensuring its service life;

[0061] When the plugging block 18 moves along with the base belt 2, that is, when the plugging block 18 is separated from the surface of the rotating drum 3, at this time, due to the elastic force of the pressing spring 19, the plugging block 18 forms a closed treatment for the extrusion channel 17, that is, a heat preservation treatment for the hollow area 16 of the base belt 2, effectively reducing the cooling rate of the base belt 2 in cold area operations or low-temperature storage environments.

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

[0063] Further, as shown in Figure 7 , it is specifically worth noting that the outer surface of the plugging block 18 located in the hollow area 16 is provided with a groove, and one end of the pressing spring 19 is arranged in the groove. The setting of the groove can play a certain guiding and limiting role for the pressing spring 19 when the pressing spring 19 is compressed, and prevent the plugging block 18 from shifting to a certain extent.

[0064] Further, as shown in Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 8 , Figure 9 and Figure 10 , it is specifically worth noting that the temperature equalizing mechanism includes a sliding plate 21, the sliding plate 21 is slidably installed on the bottom top surface of the heat conduction frame 5, and a plurality of uniformly distributed air outlet holes 22 are opened on the top surface of the heat conduction frame 5. One end of the sliding plate 21 is fixed with a push rod 23, and a fixed frame 24 is fixed between the push rod 23 and the U-shaped rack frame;

[0065] The branch pipe 25 is located outside the sliding plate 21 and is communicated with the outer surface of the heat conduction frame 5. The other end of the branch pipe 25 penetrates through the installation frame 6 and is communicated with the bottom surface of the heat supply pipe 9;

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

[0067] Further, as shown in Figure 5 , Figure 7 and Figure 9 , it is specifically worth noting that the contact surface between the heat conduction frame 5 and the outer ring of the baseband 2 is an arc surface that matches each other, which can scrape the outer ring surface of the baseband 2 to a certain extent. Combined with the extrusion and blowing formed by the reciprocating movement 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 conduction frame 5 is arranged as an inclined slope, which is beneficial for the impurities scraped or blown to fall better.

[0068] Further, as shown in Figure 1 , Figure 2 , Figure 9 and Figure 10 , it is specifically worth noting that a wiping rod 26 is rotatably connected to the outer surface of one end of the fixed frame 24 away from the sliding plate 21. The wiping rod 26 is tangent to the outer ring surface of the baseband 2. The setting of the wiping rod 26 makes it reciprocate with the reciprocating driving member, thereby driving the wiping rod 26 to perform reciprocating rolling treatment, so as to better clean the bottom surface of the outer ring of the baseband 2 during operation.

[0069] Further, as shown in Figure 1 , Figure 2 , Figure 5 and Figure 9 , it is specifically worth noting that limiting strips 27 are arranged above both ends of the two heat conduction frames 5. The two limiting strips 27 are respectively fixed to the top inner wall of the frame 1. The bottom surface of the limiting strip 27 is attached to the top surface of the outer ring of the baseband 2. The setting of the limiting strip 27, combined with the heat conduction frame 5, guides and limits the top surface of the outer ring of the baseband 2, and guides and limits the inner ring surface of the baseband 2 through the preheating frame 4 and the rotating drum 3, thereby effectively improving the stability of the baseband 2 during operation.

[0070] This solution has the following working process: Through the drive of the drive device, the baseband 2 operates on the rack 1 by the frictional force with the rotating drum 3, that is, it drives the material to be transported and transferred on the outer ring top surface of the baseband 2 to the front end of the subsequent suspension conveying system. Through the mutual cooperation of the preheating mechanism and the temperature equalizing mechanism, that is, through the mutual cooperation of the rotating drum 3 and the reciprocating drive member, the moving plate 11 on the preheating frame 4 and the sliding plate 21 on the heat conducting frame 5 perform reciprocating motions synchronously, so as to synchronously conduct heat transfer treatment on the inner and outer ring surfaces of the baseband 2 at the rotating drum 3, enabling the inner and outer ring surfaces of the baseband 2 to maintain good temperature uniformity, avoiding the hardening phenomenon of the baseband 2 during operation, and effectively avoiding material aging and performance deterioration caused by temperature difference, greatly improving the service life of the baseband 2;

[0071] The setting of the automatic opening and closing member, through its extrusion with the rotating drum 3, can reciprocate the opening and closing states of the inner ring surface of the baseband 2, so that a closed heat preservation environment is presented in the hollow area 16 at the inner ring of the baseband 2, further improving the heat preservation performance of the inner ring of the baseband 2 when it is far from the rotating drum 3, reducing the cooling rate of the baseband 2 in cold area operations or low-temperature storage environments, and significantly reducing the possibility of the hardening phenomenon of the baseband 2 during operation.
