Description

Technical Field

[0001] This invention belongs to the field of transportation device technology, specifically relating to a conveyor belt with an easy-to-disassemble lower idler roller mounting structure and a conveyor belt. Background Technology

[0002] Cigarette production involves multiple processes, from tobacco leaves to shredded tobacco and then to cigarettes. A large amount of shredded tobacco is fed upwards at an angle into a feeder, then falls out of the feeder and is fed to a disc feeder.

[0003] When transporting tobacco shreds, conveyor belts are generally used.

[0004] The lower idler is an essential component of the conveyor belt, mainly used to support the conveyor belt. The lower idler is in constant frictional contact with the conveyor belt, which can easily lead to damage to the idler bearing or wear through the idler shell. The performance of the lower idler directly affects the efficiency of the conveyor belt. Therefore, the lower idler often needs to be replaced during the operation of the conveyor belt.

[0005] The existing installation method for lower rollers mostly involves using U-bolts to fix the lower rollers to the angle steel welded to the intermediate frame. A set of lower rollers requires 2 U-bolts and 4 nuts, so the installation process for a set of lower rollers is complicated and time-consuming.

[0006] Meanwhile, in the field of tobacco leaf transportation, various supports are installed under the conveyor belt used to transport tobacco leaves. The lower idler roller is located under the conveyor belt, which may cause insufficient light and obstructed vision. When loading and unloading the idler roller, it may cause some interference and obstacles, making operation inconvenient and affecting the installation effect. Summary of the Invention

[0007] The purpose of this invention is to provide a conveyor belt with an easy-to-install and disassemble lower idler roller mounting structure and a conveyor belt, in order to solve the problem of inconvenient disassembly and assembly caused by the defects of the existing lower idler roller structure.

[0008] To achieve the above-mentioned technical objectives, the technical solution adopted by the present invention is as follows: A conveyor belt lower idler roller mounting structure that is easy to assemble and disassemble includes: The first lug and the second lug are installed on the side plates on both sides of the conveyor belt; The idler body is located below the belt, and the idler body includes an idler shaft; A connector is hinged to the first lug, and the connector has a degree of freedom to rotate up and down on the side near the second lug. The connector has a mounting hole, and one end of the roller shaft passes through the mounting hole; The lower end of the second lug has a notch, and the free end of the roller shaft is located inside the notch; A support block is movably installed inside the second ear, and the support block is located inside the notch and below the roller shaft.

[0009] Further specified, the connector is fixedly provided with a guide cylinder on the side near the second lug, and the guide cylinder is in communication with the mounting hole; The width of the free end of the guide cylinder is greater than the width of the mounting hole; The height of the free end of the guide cylinder is greater than the height of the mounting hole.

[0010] This structural design guides the roller shaft inserted into the mounting hole through the guide cylinder, making it easier for the end of the roller shaft to be inserted into the mounting hole of the connector, thus making installation more convenient.

[0011] Further specifying, the first lug has a mounting groove, and the connector is located within the mounting groove.

[0012] This structural design limits the maximum degree of freedom for the connector to deflect downwards by the bottom surface of the mounting groove, thus avoiding the problem of the connector being difficult to insert into the mounting hole due to excessive downward deflection before the lower roller is installed. It is highly practical.

[0013] Further specified, the first lug is fixedly provided with a first magnet at the top of the mounting groove; A second magnet is fixedly provided on the upper end face of the connector; The first magnet and the second magnet repel each other.

[0014] This structural design, through the mutual repulsion of the first and second magnets, causes the connector to automatically shift downwards on the side closer to the second lug before the lower roller is installed. This causes the mounting hole of the connector to shift downwards towards the second lug, making it easier to insert the roller shaft into the mounting hole, thus enhancing its practicality.

[0015] Furthermore, the hinge point between the connector and the first lug is located on the side of the connector's center of gravity away from the second lug.

[0016] This structural design, by setting the hinge point between the connector and the first lug on the side away from the second lug relative to the center of gravity of the connector, can directly utilize the weight of the connector itself to automatically deflect the connector downwards before the lower idler roller is installed.

[0017] Further specified, the support block is laterally slidably mounted on the second lug; The sidewall of the support block near the first awl is offset from top to bottom away from the first awl; The support block is screwed with a sliding bolt that passes laterally through the second ear on the side away from the first ear, and a compression spring is sleeved between the support block and the second ear on the sliding bolt.

[0018] This structural design, through the lateral sliding installation of the support block and the inclination of its side wall, allows the free end of the idler roller shaft to be inserted into the notch of the second lug by lifting it upwards. The free end of the idler roller shaft can then push against the inclination of the side wall, causing the support block to disengage from the movement path of the idler roller shaft. Once the end of the idler roller shaft disengages from the support block, the compression spring drives the support block to its reset position, thus providing support for the free end of the idler roller shaft. This design is easy to install and highly practical. When it is necessary to remove the idler roller, simply pull the sliding bolt outward or press the support block outward; disassembly is convenient.

[0019] Furthermore, both ends of the idler shaft are provided with rotation limiting mechanisms to limit the degree of freedom of the idler shaft to rotate around the first lug and / or the second lug after the idler body is installed.

[0020] This structural design limits the rotational freedom of the idler roller shaft after installation through a rotation limiting mechanism, avoiding wear on the first and / or second lugs due to the rotation of the idler roller shaft, making it highly practical.

[0021] Further specified, the first lug is provided with a first threaded hole, and the connector is provided with a through hole, the through hole communicating with the mounting hole; The end of the idler roller shaft is provided with a positioning hole in the axial direction; A first positioning bolt is screwed into the first threaded hole, and the first positioning bolt passes through the through hole and is installed in the positioning hole.

[0022] This structural design, which uses the first positioning bolt to precisely position the first support lug and the roller shaft, improves the installation accuracy of the roller body relative to the first support lug and is highly practical.

[0023] Furthermore, the second lug is provided with a second threaded hole; The end of the idler roller shaft is provided with a positioning hole in the axial direction; A second positioning bolt is screwed into the second threaded hole, and the second positioning bolt passes through the positioning hole.

[0024] This structural design uses the second positioning bolt to precisely position the second support lug and the roller shaft, and forms a second vertical support for the roller shaft on the basis of the support block, improving the installation accuracy of the roller body relative to the second support lug, and is highly practical.

[0025] A conveyor belt includes an idler body, two side plates, a belt body located between the two side plates, and the aforementioned conveyor belt with an easy-to-disassemble lower idler mounting structure. The first and second lugs are respectively mounted on a side plate; The idler roller body is installed between the first and second lugs and located below the belt.

[0026] The invention employing the above technical solution has the following advantages: The interplay of the first lug, second lug, idler shaft, connector, mounting hole, notch, and support block allows for easy installation. During installation, the idler shaft can be inserted into the connector of the first lug at an angle below the belt without touching it. Utilizing the deflection freedom of the connector, and by lifting the free end of the idler body upwards, the free end of the idler shaft is engaged in the notch of the second lug. Finally, it is supported and fixed by the support block, making installation convenient. During disassembly, simply detach the support block from the free end of the idler roller shaft, press the free end of the idler roller shaft downwards, and then pull the idler roller shaft out of the mounting hole of the connector. Disassembly is convenient. During installation, the idler roller does not need to excessively compress the belt, and it is well adaptable to situations where the conveyor belt has poor elasticity and high tension.

The symbols for the main components are explained below: Side plate 1, belt body 10 First ear 21, mounting slot 210, first magnet 211, second magnet 212 Second ear 22, notch 221 Roller body 3, roller shaft 31, groove 311, positioning hole 312 Connector 41, Mounting hole 411, Guide cylinder 412 Support block 42, sliding bolt 421, compression spring 422 First positioning bolt 51, first threaded hole 511, through hole 512, second threaded hole 513 Second positioning bolt 52. Detailed Implementation

[0028] The present invention will be described in detail below with reference to the accompanying drawings and specific embodiments. It should be noted that similar or identical parts are referred to by the same reference numerals in the drawings or description. Implementations not shown or described in the drawings are forms known to those skilled in the art. In addition, directional terms mentioned in the embodiments, such as "up," "down," "top," "bottom," "left," "right," "front," and "back," are only for reference to the directions in the drawings and are not intended to limit the scope of protection of the present invention.

[0029] like Figures 1 to 11 As shown, a conveyor belt lower idler roller mounting structure for easy assembly and disassembly according to the present invention includes: The first lug 21 and the second lug 22 are installed on the side plates 1 on both sides of the conveyor belt; The idler body 3 is located below the belt 10, and the idler body 3 includes an idler shaft 31; A connector 41 is hinged to the first lug 21, and the connector 41 has a degree of freedom to rotate up and down on the side near the second lug 22. The connector 41 has a mounting hole 411, and one end of the roller shaft 31 passes through the mounting hole 411; The lower end of the second ear 22 is provided with a notch 221, and the free end of the roller shaft 31 is located in the notch 221; A support block 42 is movably installed inside the second ear 22. The support block 42 is located inside the notch 221 and below the idler roller shaft 31.

[0030] The lower longitudinal section of notch 221 is narrow at the top and wide at the bottom.

[0031] By increasing the width of the lower end of the notch 221, the lower end of the idler roller shaft 31 can be more easily inserted into the notch 221, making installation more convenient and practical.

[0032] A guide cylinder 412 is fixedly provided on the side of the connector 41 near the second lug 22, and the guide cylinder 412 is connected to the mounting hole 411; The width of the free end of the guide cylinder 412 is greater than the width of the mounting hole 411; The height of the free end of the guide cylinder 412 is greater than the height of the mounting hole 411.

[0033] The guide tube 412 guides the roller shaft 31 inserted into the mounting hole 411, making it easier for the end of the roller shaft 31 to be inserted into the mounting hole 411 of the connector 41, thus making installation more convenient.

[0034] The first ear 21 has a mounting groove 210, and the connector 41 is located in the mounting groove 210.

[0035] In fact, the connector 41 can also be directly hinged to the side of the first lug 21 and the bottom surface of the mounting groove 210 can limit the maximum degree of freedom of the connector 41 to deflect downwards. This avoids the problem that the connector 41 is not easy to insert into the mounting hole 411 due to excessive downward deflection before the lower roller is installed. This is more practical.

[0036] The first ear 21 is fixedly provided with a first magnet 211 at the top of the mounting groove 210; A second magnet 212 is fixedly provided on the upper end face of the connector 41; The first magnet 211 and the second magnet 212 repel each other.

[0037] The mutual repulsion between the first magnet 211 and the second magnet 212 causes the connector 41 to automatically shift downwards on the side near the second lug 22 before the lower roller is installed. This causes the mounting hole 411 of the connector 41 to shift downwards towards the second lug 22, making it easier for the roller shaft 31 to be inserted into the mounting hole 411, which is highly practical.

[0038] The hinge point between the connector 41 and the first lug 21 is located on the side of the connector 41 away from the second lug 22.

[0039] By setting the hinge point between the connector 41 and the first lug 21 on the side away from the second lug 22 relative to the center of gravity of the connector 41, the connector 41 can be automatically deflected downwards before the lower idler roller is installed by directly utilizing its own weight.

[0040] The support block 42 is slidably mounted on the second lug 22; The sidewall of the support block 42 near the first lug 21 shifts from top to bottom away from the first lug 21; A sliding bolt 421, which is horizontally inserted through the second ear 22, is screwed onto the side of the support block 42 away from the first ear 21. A compression spring 422 is sleeved between the sliding bolt 421 and the second ear 22.

[0041] In practice, depending on the actual situation, the support block 42 can be detachably installed on the second lug 22 to support the free end of the idler roller shaft 31. In this embodiment, the support block 42 is laterally slidably installed, and its side wall is inclined. When the free end of the idler roller shaft 31 is inserted into the notch 221 of the second lug 22 by lifting upward, the free end of the idler roller shaft 31 can be used to push the inclined side wall in the opposite direction, so that the support block 42 is disengaged from the movement path of the idler roller shaft 31. After the end of the idler roller shaft 31 is disengaged from the support block 42, the compression spring 422 drives the support block 42 to return to its original position, thereby forming support for the free end of the idler roller shaft 31. It is easy to install and has strong practicality. When it is necessary to remove the idler roller, simply pull the sliding bolt 421 outward or press the support block 42 outward, making disassembly convenient.

[0042] Both ends of the idler shaft 31 are provided with rotation limiting mechanisms to limit the degree of freedom of the idler shaft 31 to rotate around the first lug 21 and / or the second lug 22 after the idler body 3 is installed.

[0043] The rotational freedom of the idler shaft 31 after installation is limited by the rotation limiting mechanism, which avoids the problem of wear on the first lug 21 and / or the second lug 22 due to the rotation of the idler shaft 31, and is highly practical.

[0044] The rotation limiting mechanism includes vertically formed grooves 311 on both sides of the roller shaft 31; The sidewalls of notch 221 and mounting hole 411 are both vertical planes; The groove 311 is attached to the corresponding vertical plane.

[0045] In practice, depending on the actual situation, a strip-shaped positioning groove can be opened on the upper end face of the roller shaft 31, and corresponding positioning pins can be set in the notch 221 and the mounting hole 411 to limit the rotational freedom of the roller shaft 31. In this embodiment, the rotational freedom of the roller shaft 31 is limited by the mutual contact between the groove 311 and the vertical plane. The structure is simple, easy to install, and highly practical.

[0046] The first lug 21 has a first threaded hole 511, and the connector 41 has a through hole 512, which communicates with the mounting hole 411. The end of the idler roller shaft 31 is provided with a positioning hole 312 in the axial direction; A first positioning bolt 51 is screwed into the first threaded hole 511, and the first positioning bolt 51 passes through the through hole and is installed in the positioning hole 312.

[0047] The first positioning bolt 51 is used to accurately position the first support ear 21 and the roller shaft 31, thereby improving the installation accuracy of the roller body 3 relative to the first support ear 21 and making it highly practical.

[0048] The second ear 22 has a second threaded hole 513; The end of the idler roller shaft 31 is provided with a positioning hole 312 in the axial direction; A second positioning bolt 52 is screwed into the second threaded hole 513, and the second positioning bolt 52 passes through the positioning hole 312.

[0049] The second positioning bolt 52 is used to precisely position the second support ear 22 and the roller shaft 31, and on the basis of the support block 42, a second vertical support for the roller shaft 31 is formed, which improves the installation accuracy of the roller body 3 relative to the second support ear 22 and has strong practicality.

[0050] A conveyor belt includes an idler body 3, two side plates 1, a belt body 10 located between the two side plates 1, and the aforementioned conveyor belt with an easy-to-disassemble lower idler mounting structure. The first ear 21 and the second ear 22 are respectively mounted on a side plate 1; The idler body 3 is installed between the first lug 21 and the second lug 22 and is located below the belt body 10.

[0051] In this embodiment, when it is necessary to replace the lower idler of the conveyor belt, remove the second positioning bolt 52, hold the idler body 3 by hand, and then pull the sliding bolt 421 outward, or press the support block 42 outward to make room for the movement path of the free end of the idler shaft 31. With the hinge point between the connector 41 and the first lug 21 as the center, the free end of the roller body 3 is deflected downward until the roller shaft 31 is completely disengaged from the second lug 22. Then, the roller shaft 31 is pulled out from the mounting hole 411 of the connector 41 to disassemble the roller. When it is necessary to reinstall the idler roller, support the idler roller body 3 and insert the idler roller body 3 into the belt body 10 from below with the first lug 21 in a higher position, so that the idler roller shaft 31 enters the mounting hole 411 under the guidance of the guide cylinder 412, and the first positioning bolt 51 passes through the positioning hole of the idler roller shaft 31. Then, the free end of the roller body 3 is lifted upward, and the free end of the roller shaft 31 is inserted into the notch 221 of the second lug 22, so that the free end of the roller shaft 31 rests against the inclined side wall of the support block 42. Continue lifting upwards, using the reverse pushing of the free end of the roller shaft 31 against the inclined side wall, causing the support block 42 to disengage from the movement path of the roller shaft 31, until the end of the roller shaft 31 disengages from the support block 42. Then, the compression spring 422 drives the support block 42 back to its original position, thereby forming support for the free end of the roller shaft 31. Finally, the second positioning bolt 52 is screwed into the second threaded hole 513, so that the second positioning bolt 52 passes through the positioning hole 312 at the free end of the roller shaft 31.

[0052] The foregoing has provided a detailed description of the easy-to-assemble and disassemble lower idler roller mounting structure and the conveyor belt provided by the present invention. The specific embodiments described are merely for the purpose of helping to understand the method and core ideas of the present invention. It should be noted that those skilled in the art can make various improvements and modifications to the present invention without departing from its principles, and these improvements and modifications also fall within the protection scope of the claims of the present invention.
