Description

Technical Field

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

[0002] In industrial sectors such as mining, port transshipment, and building materials processing, conveyor belts are core equipment for the continuous transport of bulk materials (such as ore, coal, and sand), and their operational stability directly determines production efficiency.

[0003] The core function of conveyor belts is to realize the long-distance, continuous transport of materials. Their application scenarios have significant common characteristics. In high-impact material drop environments, when materials (such as ores with a particle size of 10-500mm and lump coal) fall onto the surface of the conveyor belt through devices such as feed hoppers and chutes, instantaneous impact loads are generated, which can easily cause local indentation and cracking of the conveyor belt. As a result, the conveyor belt will tear longitudinally or laterally due to shear force. At the same time, some materials (such as wet coal, clay, and cement clinker) are prone to adhering to the surface of the conveyor belt during the transport process. Adhering materials will enter the gap between idlers and rollers with the conveyor belt, or accumulate and clump in the return section, which can easily cause scratches on the surface of the conveyor belt due to the presence of foreign objects, thereby increasing the risk of tearing of the conveyor belt. To address this, we propose a tear-resistant conveyor belt. Summary of the Invention

Detailed Implementation

[0026] 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. Example

[0027] Please see Figures 1-7 The tear-resistant conveyor belt shown in the figure includes four supports 101 arranged symmetrically in pairs. A drive roller 103 is rotatably connected between two opposing supports 101. The two drive rollers 103 are connected by a drive belt 102. The belt also includes a support mechanism disposed between the two drive rollers 103 to support the material impact zone of the drive belt 102 and a processing mechanism for surface treatment of the return zone of the drive belt 102.

[0028] The support mechanism includes two first U-shaped plates 201 slidably connected between two transmission rollers 103. A first support roller 202 is rotatably connected to the side of the two first U-shaped plates 201 near the material drop area of ​​the transmission belt 102. The two first U-shaped plates 201 are connected to each other by a connecting plate 203. A second U-shaped plate 204 is connected to the side of the connecting plate 203 away from the first support roller 202 by an adjustment component. A second support roller 205 is rotatably connected to the side of the second U-shaped plate 204 away from the connecting plate 203. The inner surface of the transmission belt 102 is slidably connected to the two first support rollers 202 and the second support roller 205. The two brackets 101 are provided with buffer components for buffering the impact force received by the two first support rollers 202.

[0029] It should be noted here that: by setting up the support mechanism, the instantaneous impact force on the material drop area of ​​the transmission belt 102 is reduced under the action of the buffer component, thereby reducing the risk of longitudinal or transverse tearing of the transmission belt 102 due to the instantaneous impact shear force.

[0030] Please see Figure 3 and Figure 4 The buffer assembly shown in the figure includes a long strip plate 301 fixedly connected to the side of two adjacent supports 101 near the first support roller 202. Two first fixing plates 302 are fixedly connected between the two long strip plates 301. Two damping buffers 303 are respectively hinged to the side of the two first fixing plates 302 near the first support roller 202. The end of the four damping buffers 303 away from the first fixing plates 302 is hinged to the connecting plate 203.

[0031] It should be noted here that: by setting up the buffer component, the damping element of the damping buffer 303 interacts with the medium to convert the kinetic energy of the moving object into unusable energy such as heat energy and sound energy and dissipate it, thereby slowing down the movement speed of the transmission belt 102 and reducing the instantaneous impact force on the transmission belt 102.

[0032] Please see Figure 3 and Figure 4 The adjustment assembly shown in the figure includes a second fixing plate 401 fixedly connected to two opposite side walls of the connecting plate 203. T-shaped rods 402 are slidably connected to the two second fixing plates 401. One end of each of the two T-shaped rods 402 is connected to a second U-shaped plate 204. A push rod motor 403 is provided on the side of the connecting plate 203 away from the second support roller 205. An adjustment rod 404 is fixedly connected to the output end of the push rod motor 403. The end of the adjustment rod 404 away from the push rod motor 403 is connected to the second U-shaped plate 204 through a pressure sensor 405.

[0033] It should be noted here that by adjusting the settings of the components, the tension of the transmission belt 102 can be flexibly adjusted according to the usage of the transmission belt 102.

[0034] Please see Figure 5 and Figure 6 The processing mechanism shown in the figure includes a processing frame 501 slidably connected to the side of the transmission belt 102 away from the second support roller 205. The processing frame 501 is connected to a processing plate 502 via an extrusion assembly on the side of the transmission belt 102. A scraper 503 is fixedly connected to the side of the processing plate 502 away from the processing frame 501. The long strip 301 is provided with a pushing assembly for pushing the scraper 503.

[0035] It should be noted that, through the arrangement of the processing mechanism, the scraper 503 reciprocates laterally on the surface of the transmission belt 102 by the coordinated action of the moving component, the driving component, and the pushing component. This improves the scraper 503's effect on removing impurities adhering to the surface of the transmission belt 102, thereby ensuring the cleanliness of the transmission belt 102 surface. This reduces the risk of scratches on the conveyor belt surface due to the presence of foreign objects, and further reduces the risk of tearing of the conveyor belt.

[0036] Please see Figure 5 and Figure 6 The extrusion assembly shown in the figure includes an extrusion plate 601 slidably connected to the processing frame 501. The side of the processing plate 502 away from the scraper 503 is connected to the extrusion plate 601. A plurality of extrusion springs 602 are fixedly connected to the side of the extrusion plate 601 away from the processing plate 502. The end of each extrusion spring 602 away from the extrusion plate 601 is connected to the bottom wall of the processing frame 501.

[0037] It should be noted that the extrusion assembly facilitates the application of elastic extrusion force to the scraper 503, thereby ensuring that the scraper 503 remains in contact with the surface of the transmission belt 102.

[0038] Please see Figure 5 and Figure 6 The push assembly shown in the figure includes a third fixed plate 701 fixedly connected to the two long strip plates 301 near the processing frame 501. The two third fixed plates 701 are fixedly connected to push tubes 702. The two push tubes 702 near the processing frame 501 are connected to push rods 704 through guide components. The opposite ends of the two push rods 704 are connected to the processing frame 501. The ends of the two push rods 704 that are far apart from each other are located inside the push tubes 702 and are fixedly connected to push plates 703. The second U-shaped plate 204 is provided with a drive assembly for driving the push plates 703.

[0039] It should be noted here that by setting up the push component, it is easy to achieve reciprocating pushing of scraper 503.

[0040] Please see Figure 5 and Figure 6 The guide assembly shown in the figure includes a plurality of guide grooves 801 arranged in a ring array on the side wall of the push rod 704. Each guide groove 801 is slidably connected to a guide plate 802. The side of each guide plate 802 that is far away from each other is connected to the inner wall of the push tube 702.

[0041] It should be noted here that the guide component provides guidance and limit for the movement of the push rod 704.

[0042] Please see Figure 5 and Figure 6The driving assembly shown in the figure includes a fixed tube 901 fixedly connected to the side of the second U-shaped plate 204 near the push tube 702, a driving tube 902 fixedly connected to the side wall of the fixed tube 901, the side of the driving tube 902 away from the fixed tube 901 being connected to the push tube 702 through a corrugated tube 903, a driving plate 904 slidably connected inside the driving tube 902, and a moving assembly for reciprocating movement of the driving plate 904 provided in the fixed tube 901.

[0043] It should be noted here that the drive component is configured to facilitate the movement of the push rod 704.

[0044] Please see Figure 5 and Figure 6 The movable component shown in the figure includes a movable rod 1001 rotatably connected to a fixed tube 901. One end of the movable rod 1001 is connected to a second support roller 205. A triangular plate 1002 is fixedly connected to the side wall of the movable rod 1001. A sliding rod 1003 is slidably connected to the side of the drive tube 902 near the triangular plate 1002. One end of the sliding rod 1003 is connected to a drive plate 904. A return spring 1004 is fixedly connected to the side of the drive plate 904 away from the sliding rod 1003. The end of the return spring 1004 away from the drive plate 904 is connected to the bottom wall of the drive tube 902.

[0045] It should be noted that by setting up the moving component, the rotation of the second support roller 205 can be used to achieve reciprocating push of the drive plate 904, thereby saving energy expenditure while achieving reciprocating push of the push rod 704.

[0046] Please see Figure 3 and Figure 5 The figure shows that a collection assembly is provided between the two third fixed plates 701 for collecting impurities on the surface of the transmission belt 102. The collection assembly includes an L-shaped plate 1101 fixedly connected to the side of the two third fixed plates 701 away from the second support roller 205. A collection box 1102 is detachably connected between the two L-shaped plates 1101. The collection box 1102 is located below the scraper 503.

[0047] It should be noted here that the collection component is configured to collect impurities scraped off the surface of the drive belt 102.

[0048] Working principle: During use, the conveyor belt can transport materials by continuously driving the transmission belt 102. During the material transport process, the transmission belt 102 located between the two first support rollers 202 is placed in the material drop zone. When the material falls from the drop port onto the surface of the transmission belt 102, it will impact the surface of the transmission belt 102 under the action of gravity. When the transmission belt 102 is subjected to the impact of gravity, the drop zone of the transmission belt 102 will sink under the action of gravity, thereby causing the two first support rollers 202 to be impacted synchronously. During the synchronous impact of the two first support rollers 202, the damping element of the damping buffer 303 interacts with the medium to convert the kinetic energy of the moving object into unusable energy such as heat energy and sound energy and dissipate it, thereby slowing down the movement speed of the transmission belt 102 and reducing the instantaneous impact force on the transmission belt 102. This reduces the risk of longitudinal or transverse tearing of the transmission belt 102 due to the instantaneous impact shear force.

[0049] Furthermore, when the two first support rollers 202 are impacted and move downward, they will simultaneously push the second support roller 205 downward. In turn, the second support roller 205 pushes the return section of the transmission belt 102, so that the transmission belt 102 maintains tension stability. This ensures that the two first support rollers 202 and the transmission belt 102 maintain appropriate contact pressure, thus ensuring that the transmission belt 102 plays a better buffering role.

[0050] Simultaneously, during the transmission process of the transmission belt 102, the scraper 503, under the squeezing action of the extrusion assembly, abuts against the surface of the return section of the transmission belt 102. Thus, the scraping action of the scraper 503 achieves surface cleaning of the transmission belt 102. Furthermore, during the rotation of the second support roller 205, it synchronously drives the triangular plate 1002 on the side wall of the moving rod 1001 to rotate. During the rotation of the triangular plate 1002, when the triangular plate 1002 abuts against the sliding rod 1003, it will... Under the interaction force, the drive plate 904 at one end of the sliding rod 1003 moves in the drive tube 902. When the drive plate 904 moves in the drive tube 902, the gas in the drive tube 902 will be pushed from the bellows 903 to the push tube 702 under the squeezing action of the drive plate 904. Then, under the action of the air pressure difference, the push plate 703 in the push tube 702 will be pushed to move. Then, the push rod 704 will be used to move the scraper 503 in the processing frame 501 on the surface of the transmission belt 102.

[0051] When the triangular plate 1002 passes the sliding rod 1003, under the elastic action of the return spring 1004, it will drive the drive plate 904 to slide in the opposite direction within the drive tube 902. Then, under the action of air pressure difference, the scraper 503 in the processing frame 501 will move in the opposite direction on the surface of the transmission belt 102. Therefore, during the continuous rotation of the second support roller 205, the scraper 503 can reciprocate laterally on the surface of the transmission belt 102 by utilizing the cooperation of the moving component, the driving component, and the pushing component. This improves the treatment effect of the scraper 503 on the surface of the transmission belt 102, thereby ensuring the cleanliness of the surface of the transmission belt 102 and reducing the risk of scratches on the surface of the conveyor belt due to the presence of foreign objects, thus further reducing the risk of tearing of the conveyor belt.
