Description

Technical Field

[0001] This invention relates to the field of conveyor belt mechanism technology, and specifically proposes a conveyor belt mechanism for conveying machinery. Background Technology

[0002] Conveyor belt mechanisms are one of the most core and common forms of long-distance continuous conveying machinery. They utilize a circulating flexible conveyor belt as a load-bearing and traction component to achieve long-distance continuous material transport along a specific route. The movement principle of the conveyor belt is friction drive. The rollers drag the entire heavy conveyor belt and the material on it through the friction between their surfaces and the conveyor belt. In order to ensure that the conveyor belt can move normally, efficiently, and stably, the surface of the rollers must be coated with rubber, which can significantly increase the friction coefficient of the roller surface, thereby generating greater traction, ensuring effective power transmission, and preventing slippage.

[0003] However, during transportation, the conveyor belt surface (especially the internal reinforcing skeleton or embedded hard impurities) will continuously and subtly scrape the rubber-coated surface like sandpaper. The microscopic protrusions on the rubber-coated surface are gradually worn down, which will cause the conveyor belt to slip. When slipping, the conveyor belt rubs against the roller at high speed, generating a lot of heat, which will severely wear down or even burn the conveyor belt surface and also affect the material conveying efficiency. Therefore, it is necessary to replace the rubber coating on the roller surface regularly. When replacing it, the entire conveying equipment must be shut down and the roller and conveyor belt must be disassembled. Especially for long-distance conveying mechanisms, the conveyor belt itself is very heavy. After disassembling and replacing the rubber coating, the conveyor belt must be reinstalled and the tension and anti-deviation adjustments must be made. Therefore, the whole operation process is not only cumbersome but also extremely time-consuming, affecting the material conveying efficiency.

[0004] Therefore, there is an urgent need for a conveyor belt mechanism for conveying machinery that facilitates the replacement of the rubber coating on the rollers. Summary of the Invention

[0005] To address the aforementioned problems, the present invention provides a conveyor belt mechanism for conveying machinery, which solves the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention employs the following technical solution: a conveyor belt mechanism for conveying machinery, comprising a conveyor belt for transporting materials and a frame for supporting installation; a roller assembly for driving the conveyor belt is mounted on the surface of the frame, and a drive assembly for driving the roller assembly to rotate is mounted on the surface of the frame; the roller assembly comprises three support components that can form a complete cylindrical shape; each support component comprises a support block with an arc-shaped cross-section; a detachable sleeve is slidably mounted on the surface of the support block; a self-rotating and replaceable rubber coating is fitted onto the surface of the sleeve; a rotatable circular roller is mounted on the inner side of the support block, the circular roller abuts against the inner wall of the rubber coating, and the rubber coating rotates to abut against the inner wall of the conveyor belt; the drive assembly comprises connectors fixedly mounted at both ends of the support blocks; the connectors at the same end of the three support blocks are fixedly mounted through a connecting assembly; the rubber coatings on the surfaces of the three sleeves are rotated and replaced sequentially for individually abutting against the inner wall of the conveyor belt; the sleeves on the surfaces of the three support blocks are disassembled and replaced sequentially for overall rotation and abutment against the inner wall of the conveyor belt.

[0007] Preferably, the surface of the support block has multiple sets of guide grooves, and the sleeve has a guide rod fixedly installed inside the sleeve, which corresponds to the position of the guide groove. The guide rod is movably installed inside the guide groove.

[0008] Preferably, the surface of the support block is provided with a mounting groove, and an electric actuator for driving the roller to move is fixedly installed inside the mounting groove. The roller is rotatably assembled in the mounting groove by a mounting bracket. The surface of the sleeve is provided with a through transverse groove, and the mounting bracket is located inside the transverse groove.

[0009] Preferably, the two ends of the sleeve are fixedly installed with anti-detachment edges protruding from their edges, and the two ends of the rubber coating abut against the surface of the anti-detachment edges.

[0010] Preferably, the connector has an arc-shaped cross-section, with a straight inner surface and an inclined surface on the other side. The connecting assembly includes a collar fitted onto the surface of the connector. The surface of the collar has a groove that matches the cross-sectional shape of the connector. The end of the collar is fitted with a rotating rod that drives its rotation.

[0011] Preferably, the collar is coaxially rotatably fitted with a support circular plate for supporting the inner side of the connector. The support circular plate is coaxially fixedly fitted with a rotating rod two. The rotating rod two is coaxially rotatably fitted with the rotating rod. The rotating rod two is fitted inside the frame. The frame is fitted with a threaded rod for driving the collar to translate.

[0012] Preferably, an arc-shaped outer ring is fixedly installed at one end of the inclined arc side of the connector, and the outer ring abuts against the inner wall of the frame.

[0013] Preferably, an electric actuator two is fixedly mounted on the surface of the supporting circular plate, and the output shaft of the electric actuator two abuts against the inner side of the corresponding connector.

[0014] Preferably, the drive assembly includes a mounting plate inside the frame, and gears are fitted on the surface of the mounting plate and the surface of the rotating rod. The two gears mesh to drive each other, and the end of the threaded rod abuts against the surface of the mounting plate.

[0015] The above technical solution has the following advantages or beneficial effects: 1. The present invention provides a conveyor belt mechanism for conveying machinery. By setting three support components, the roller assembly is divided into three parts. When the rubber coating on the surface of the roller assembly is worn smooth, the corresponding support component that is rotated away from the conveyor belt can be moved away from the other two support components, thereby replacing the rubber coating by rotation. The rubber coating of each support component is replaced in this way. The rubber coating replacement on each support component takes only a few minutes. It does not require disassembly and installation of long-distance conveyor belts, as well as subsequent debugging work, which effectively simplifies the rubber coating replacement operation process, greatly improves the efficiency of rubber coating replacement, reduces the overall replacement frequency, and reduces downtime.

[0016] 2. By setting up a sleeve, a support block, and a rubber coating, after all the rubber coatings have been replaced and used, the sleeve can be directly pulled out from the surface of the support block and a new sleeve with a new rubber coating can be installed. The whole process does not require the overall disassembly of the conveyor belt and roller assembly, which greatly improves the efficiency of rubber coating replacement and further reduces downtime.

Detailed Implementation

[0028] 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.

[0029] To enable those skilled in the art to better understand the present invention, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0030] Figure 1 A conveyor belt mechanism for conveying is disclosed, including a conveyor belt 1 for conveying materials and two roller assemblies 3. The conveyor belt 1 is sleeved on the surface of the two roller assemblies 3. The two roller assemblies 3 tension the conveyor belt. When the roller assemblies 3 rotate, they can drive the conveyor belt 1 to circulate. A frame 2 is installed at each end of the roller assembly 3. The frame 2 is supported on the ground. A drive assembly 4 is installed inside the frame 2. The drive assembly 4 is used to drive the roller assembly 3 to rotate.

[0031] like Figures 4-9 As shown, the roller assembly 3 includes three support components 31. Each support component 31 has a cross-section of one-third of a circle. After the three support components 31 are assembled, the cross-section is a complete circle. During the rotation of the roller assembly 3, there may be a situation where two of the support components 31 are in contact with the inner wall of the conveyor belt 1 while the other support component 31 is not in contact with the inner wall of the conveyor belt 1. At this time, the rotation of the roller assembly 3 is stopped, and the support component 31 at that position can be disassembled individually.

[0032] The support assembly 31 includes a support block 311 with an arc-shaped cross section. A sleeve 312, which is adapted to the shape of the support block 311, is slidably fitted onto the surface of the support block 311. In order to prevent the sleeve 312 from sliding during use, in this embodiment, two guide rods 6 are fixedly installed inside the sleeve 312. A guide groove 5 is opened at the corresponding position on the surface of the support block 311. The guide rods 6 are interference-fitted inside the guide groove 5. The surface of the sleeve 312 is fitted with a rubber coating 314, which is in contact with the inner wall of the conveyor belt 1. When the surface of the rubber coating 314 is worn smooth to a certain extent, the three support assemblies 31 can be rotated and moved to a position away from the conveyor belt 1 in sequence. After stopping the machine, the support assembly 31 at that position can be quickly removed and the rubber coating 314 on its surface can be quickly replaced. At this time, it is not necessary to disassemble the entire conveyor belt 1 and roller assembly 3, which reduces downtime and makes operation more convenient.

[0033] It should be noted that the wear of the 314 rubber coating to the point where it needs to be replaced is the result of long-term testing by those skilled in the art. This is to avoid frequent replacements that would increase operating costs, and also to prevent the conveyor belt 1 from slipping, which would cause the conveyor belt 1 to be subjected to high-speed friction and thus affect its normal use.

[0034] A transverse mounting groove 7 is formed on the surface of the support block 311. An electric actuator 8 is fixedly installed inside the mounting groove 7. A mounting frame 9 is installed on the arc-shaped inner side of the support block 311. A circular roller 313 is installed inside the mounting frame 9. A through transverse groove 10 is formed on the surface of the sleeve 312. The mounting frame 9 is located inside the transverse groove 10. A motor for driving the circular roller 313 to rotate is also mounted on the surface of the mounting frame 9. The surface of the circular roller 313 abuts against the inner wall of the rubber coating 314. The output rod of the electric actuator 8 is connected to the surface of the mounting frame 9. The rotation of the circular roller 313 causes the rubber coating 314 to rotate. When replacing the rubber coating 314 on the curved surface, after the rubber coating 314 is rotated and replaced, the electric push rod 8 pushes the mounting frame 9 to move. The round roller 313 on the surface of the mounting frame 9 can then press the rubber coating 314 against it, ensuring the stability of the installation after the rubber coating 314 is replaced. In order to prevent the rubber coating 314 from shifting when rotating, anti-detachment edges 11 are fixedly installed at both ends of the sleeve 312. The two ends of the rubber coating 314 abut against the surface of the anti-detachment edges 11. After all the rubber coatings 314 on the sleeve 312 have been rotated and replaced, the sleeve 312 can be directly pulled off the surface of the support block 311 to replace the rubber coating 314 as a whole.

[0035] like Figures 1-5As shown, the drive assembly 4 includes connectors 41 that are fixedly installed at both ends of the support block 311. The connectors 41 at the same end of the three support blocks 311 are installed and fixed by the connecting assembly 42. In order to further ensure the stability of the rubber coating 314 on the surface of the sleeve 312 during the conveying process of the conveyor belt 1, it is necessary to ensure that the adjacent support assemblies 31 can be connected more tightly. At this time, the friction between the adjacent rubber coatings 314 is greater and the stability is also higher.

[0036] The connector 41 has an arc-shaped cross-section, with the inner side of the connector 41 being a straight arc and the outer side being a sloping arc. The connecting assembly 42 includes a collar 421 that is sleeved on the surface of the connector 41. In this embodiment, the surface of the collar 421 has three slots 423. The inner wall shape of the slots 423 is adapted to the shape of the connector 41. The closer the collar 421 moves to the end of the support block 311, the more the sloping surface of the slots 423 will press against the sloping surface of the connector 41, thereby ensuring that the three connectors 41 are installed more tightly. A rotating rod 422 that can drive the collar 421 to rotate is fixedly installed at the end of the collar 421. When the rotating rod 422 rotates, it will drive the collar 421 to rotate, thereby driving the support assembly 31 to rotate through the collar 421. The rotating rod 422 is installed inside the frame 2.

[0037] Three connectors 41 have a support circular plate 12 movably mounted on their inner sides. The surface of the support circular plate 12 abuts against the inner wall of the connector 41. The support circular plate 12 is coaxially mounted with the collar 421. A rotating rod 13 is coaxially rotatably mounted on the surface of the support circular plate 12. The rotating rod 13 is fixedly mounted inside the frame 2. It should be noted that the rotating rod 422 and the rotating rod 13 are coaxially rotatably assembled. The surface of the rotating rod 13 is slidably fitted with a linear bearing (not shown in the figure). The rotating rod 422 is fixedly fitted onto the surface of the linear bearing to ensure that the rotating rod 422 can rotate and translate on the surface of the rotating rod 13. An arc-shaped outer ring 15 is fixedly mounted on one end of the inclined arc surface of the connector 41. The surface of the outer ring 15 abuts against the inner wall of the frame 2. The connector 41 is held and stabilized by the frame 2 and the support circular plate 12. The frame 2 is internally connected to the mounting plate 43. A gear 44 is rotatably mounted on the surface of the mounting plate 43. The same gear 44 is also mounted on the surface of the rotating rod 422. The two gears 44 mesh with each other. A motor (not shown in the figure) is mounted on the mounting plate 43 to drive the gear 44 to rotate. A threaded rod 14 is threaded on the surface of the frame 2. The end of the threaded rod 14 abuts against the surface of the mounting plate 43 to ensure that the collar 421 can tightly abut against the surface of the connector 41. It should be noted that, in order to ensure stability during the rotation of the roller assembly 3, after the collar 421 is stably abutting against the surface of the connector 41, the mounting plate 43 needs to be fixed inside the frame 2 by bolts.

[0038] To facilitate the disassembly of sleeve 312, an electric actuator 16 for moving the support assembly 31 is fixedly installed on the surface of the support circular plate 12. When the corresponding rubber coating 314 needs to be replaced after a certain period of use, the collar 421 moves away from the connector 41, and the output shaft of the electric actuator 16 pushes the corresponding connector 41 to move. At this time, the rubber coating 314 can be rotated for replacement. When the corresponding rubber coating 314 is worn to the point that it needs to be replaced as a whole, the collar 421 moves completely away from the connector 41, and the support assembly 31 at this position can be directly disassembled. The other two support assemblies 31 are clamped by the frame 2 and the support circular plate 12, making the disassembly and installation process more convenient.

[0039] It should be noted that in existing systems, both the roller assembly 3 and the conveyor belt 1 need to be completely disassembled. After disassembly and replacement of the roller assembly 3, the conveyor belt 1 needs to be reassembled onto the surface of the roller assembly 3. To ensure the normal conveying function of the conveyor belt 1, multiple tension and anti-deviation adjustments are required. However, in this invention, the roller assembly 3 is divided into three support components 31. During the rotation of the roller assembly 3, one support component 31 will not contact the conveyor belt 1. At this time, the support component 31 at this position moves away from the other two support components 31, and the rubber coating 314 is rotated and replaced by the roller 313. Although the rotation needs to be stopped for a few minutes each time the rubber coating 314 is replaced, the replacement process is automatic, which is not only more convenient to use but also effectively reduces the time required for replacement. The overall replacement frequency is reduced. When all the rubber coatings 314 are worn to a certain extent, it is only necessary to remove the sleeve 312 on the surface of the support component 31 away from the conveyor belt 1 to replace the rubber coatings 314, which is more convenient to use. Although the roller assembly 3 structure in this invention is more complex than that in the prior art, they are all conventional mechanical structures without high-cost precision parts. Therefore, the increased cost is low. Moreover, since the replacement time of the rubber coatings 314 is accelerated, the downtime of the conveyor belt 1 is effectively reduced, so the efficiency of the conveyor belt 1 in transporting materials is also higher, thus achieving higher efficiency. After one assembly, it can be reused. Therefore, the increased structural cost can be completely ignored. The above technical solution of this invention is a specific improvement based on the above-mentioned prior art and to solve the technical problems.
