Description

Technical Field

[0001] The invention belongs to the technical field of transportation devices, and in particular relates to a lower roller installation structure for a conveyor belt which is easy to disassemble and assemble, and a conveyor belt. Background Art

[0002] Cigarette production requires multiple processes from tobacco leaves to tobacco shreds and then to the production of cigarette sticks. Among them, a large amount of tobacco shreds must be transported upward into the dropper at an angle, and then fall out of the dropper and then transported to the disc feeder.

[0003] When transporting tobacco, a conveyor belt is generally used for transportation.

[0004] The lower roller is a necessary component of the conveyor belt and is mainly used to support the conveyor belt. The lower roller is in long-term friction contact with the conveyor belt, which may easily cause the roller bearing to be damaged or the roller shell to be worn out. The performance of the lower roller directly affects the efficiency of the conveyor belt. Therefore, the lower roller often needs to be replaced during the operation of the conveyor belt.

[0005] Most of the existing installation methods of lower rollers use U-bolts to fix the lower rollers to the angle steel welded on the middle frame. A set of lower rollers requires 2 U-bolts and 4 nuts. Therefore, the process of installing a set of lower rollers is cumbersome and time-consuming.

[0006] At the same time, in the field of tobacco transportation, various brackets are installed under the conveyor belt used to transport tobacco leaves, and the lower rollers are located under the conveyor belt, resulting in insufficient light and blocked vision. When loading and unloading the rollers, certain interference and obstruction may occur, resulting in inconvenient operation and affecting the installation effect. Summary of the invention

[0007] The purpose of the present invention is to provide a lower roller installation structure and a conveyor belt that are easy to disassemble and assemble for a conveyor belt, so as to solve the problem of inconvenient disassembly and assembly caused by structural defects of the lower rollers of the existing conveyor belts.

[0008] In order to achieve the above technical objectives, the technical solution adopted by the present invention is as follows: A lower roller installation structure for a conveyor belt that is easy to assemble and disassemble comprises: The first and second lugs are installed on the side plates on both sides of the conveyor belt; A roller body located below the belt body, wherein the roller body includes a roller shaft; A connecting piece is hinged on the first support ear, and the connecting piece has a degree of freedom of upward and downward deflection on a side close to the second support ear; The connecting piece is provided with a mounting hole, and one end of the roller shaft is inserted into the mounting hole; A notch is formed at the lower end of the second support ear, and the free end of the roller shaft is located in the notch; A support block is movably installed inside the second support ear, and the support block is located in the notch and below the roller shaft.

[0009] It is further defined that a guide cylinder is fixedly provided on a side of the connecting member close to the second support ear, and the guide cylinder is communicated with the mounting hole; The width dimension of the free end of the guide cylinder is greater than the width dimension of the mounting hole; The height dimension of the free end of the guide cylinder is greater than the height dimension of the mounting hole.

[0010] Such a structural design guides the roller shaft inserted into the mounting hole through the guide cylinder, so that the end of the roller shaft can be more easily inserted into the mounting hole of the connecting piece, and the installation is more convenient.

[0011] It is further defined that a mounting groove is formed on the first support ear, and the connecting member is located in the mounting groove.

[0012] This structural design limits the maximum freedom of the connecting member to deflect downward by the bottom surface of the mounting groove, thereby avoiding the problem of the connecting member being inconvenient to insert the roller shaft into the mounting hole due to excessive downward deflection before the lower roller is installed. The structural design is very practical.

[0013] It is further defined that the first ear is fixedly provided with a first magnet at the top of the mounting slot; A second magnet is fixedly provided on the upper end surface of the connecting member; The first magnet and the second magnet repel each other.

[0014] Such a structural design, through the mutual repulsion between the first magnet and the second magnet, causes the connecting member to automatically shift downward on the side close to the second ear before the lower roller is installed on the connecting member, so that the mounting hole of the connecting member, in this state, is in a state of shifting from top to bottom toward the second ear, so that the roller shaft can be more conveniently inserted into the mounting hole, and the practicality is strong.

[0015] It is further defined that the hinge point between the connecting member and the first support ear is located on a side of the center of gravity of the connecting member away from the second support ear.

[0016] This structural design, by setting the hinge point between the connector and the first ear at a side away from the second ear relative to the center of gravity of the connector, can directly utilize the connector's own gravity to automatically deflect the connector downward before installing the lower roller.

[0017] It is further defined that the support block is laterally slidably mounted on the second lug; The side wall of the support block close to the first support ear is offset from top to bottom in a direction away from the first support ear; A sliding bolt transversely penetrating the second support ear is threadedly connected to the support block on one side away from the first support ear, and a compression spring is sleeved between the support block and the second support ear.

[0018] Such a structural design is installed by lateral sliding of the support block, in coordination with the inclination of its side wall. When the free end of the roller shaft is inserted into the notch of the second support ear by lifting upward, the free end of the roller shaft can be used to push the inclined side wall in the opposite direction, so that the support block is separated from the movement path of the roller shaft until the end of the roller shaft is separated from the support block, and the support block is driven by the compression spring to reset, thereby forming support for the free end of the roller shaft. The installation is convenient and the practicability is strong. When the lower roller needs to be disassembled, the sliding bolt is pulled outward or the supporting block is pressed outward, which makes disassembly convenient.

[0019] It is further defined that both ends of the roller shaft are provided with a rotation limiting mechanism for limiting the freedom of the roller shaft to rotate around the first support ear and / or the second support ear after the roller body is installed.

[0020] Such a structural design limits the rotational freedom of the roller shaft after installation through the rotation limiting mechanism, thereby avoiding the problem of wear of the first lug and / or the second lug due to the rotation of the roller shaft, and is highly practical.

[0021] It is further defined that a first threaded hole is formed on the first support ear, a through hole is formed on the connecting member, and the through hole is connected to the mounting hole; A positioning hole is axially provided at the end of the roller shaft; A first positioning bolt is threaded in the first threaded hole, and the first positioning bolt passes through the through hole and is arranged in the positioning hole.

[0022] Such a structural design can accurately position the first support ear and the roller shaft through the first positioning bolt, thereby improving the installation accuracy of the roller body relative to the first support ear and having strong practicality.

[0023] It is further defined that the second lug is provided with a second threaded hole; A positioning hole is axially provided at the end of the roller shaft; A second positioning bolt is threaded in the second threaded hole, and the second positioning bolt passes through the positioning hole.

[0024] This structural design can accurately position the second support ear and the roller shaft through the second positioning bolt, and form a second vertical support for the roller shaft based on the support block, thereby improving the installation accuracy of the roller body relative to the second support ear and having strong practicality.

[0025] A conveyor belt comprises a roller body, two side plates, a belt body located between the two side plates and a lower roller mounting structure for the conveyor belt that is easy to disassemble and assemble; The first support ear and the second support ear are respectively mounted on a side plate; The roller body is installed between the first support ear and the second support ear and is located below the belt body.

[0026] The invention adopting the above technical solution has the following advantages: Through the mutual cooperation of the first support ear, the second support ear, the roller shaft, the connecting piece, the mounting hole, the notch and the support block, during installation, one end of the roller shaft can be inserted into the connecting piece of the first support ear at an inclined angle below the belt body without touching the belt body, and the free end of the roller shaft is inserted into the notch of the second support ear by using the deflection freedom of the connecting piece and then lifting the free end of the roller body upward, and finally supported and fixed by the support block, so that the installation is convenient; When disassembling, the support block is separated from the support of the free end of the roller shaft, and the free end of the roller shaft is pressed downward, and then the roller shaft is pulled out from the mounting hole of the connecting piece, which is convenient for disassembly; When the present invention is installed, the roller body does not need to excessively squeeze the belt body, and the adaptability is good when the belt body of the conveyor belt has poor elasticity and high tension.

DETAILED DESCRIPTION

[0028] The present invention will be described in detail below in conjunction with the accompanying drawings and specific embodiments. It should be noted that in the drawings or descriptions of the specification, similar or identical parts use the same figure numbers, and the implementation methods not shown or described in the drawings are forms known to ordinary technicians in the relevant technical field. In addition, the directional terms mentioned in the embodiments, such as "upper", "lower", "top", "bottom", "left", "right", "front", "back", etc., are only referenced to the directions of the drawings and are not used to limit the scope of protection of the present invention.

[0029] like Figures 1 to 11 As shown, a lower roller installation structure for a conveyor belt that is easy to assemble and disassemble of the present invention comprises: A first lug 21 and a second lug 22 mounted on the side plates 1 on both sides of the conveyor belt; A roller body 3 is located below the belt body 10, and the roller body 3 includes a roller shaft 31; A connecting piece 41 is hinged on the first ear 21, and the connecting piece 41 has the freedom to deflect up and down on the side close to the second ear 22; The connecting member 41 is provided with a mounting hole 411, and one end of the roller shaft 31 is inserted into the mounting hole 411; A notch 221 is formed at the lower end of the second support ear 22, and the free end of the roller shaft 31 is located in the notch 221; A support block 42 is movably mounted inside the second support ear 22 . The support block 42 is located inside the notch 221 and below the roller shaft 31 .

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

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

[0032] A guide cylinder 412 is fixedly provided on one side of the connecting member 41 close to the second support ear 22, and the guide cylinder 412 is communicated with 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 dimension of the free end of the guide cylinder 412 is greater than the height dimension of the mounting hole 411 .

[0033] The roller shaft 31 inserted into the mounting hole 411 is guided by the guide cylinder 412 so that the end of the roller shaft 31 can be more easily inserted into the mounting hole 411 of the connector 41, making installation more convenient.

[0034] The first ear 21 defines a mounting groove 210 , and the connecting member 41 is located in the mounting groove 210 .

[0035] In fact, the connecting member 41 can also be directly hinged on the side of the first support ear 21 to limit the maximum freedom of the connecting member 41 to deflect downward through the bottom of the mounting groove 210, so as to avoid the problem that the connecting member 41 is inconvenient to insert the roller shaft 31 into the mounting hole 411 due to excessive downward deflection before the lower roller is installed. This is very practical.

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

[0037] Through the mutual repulsion between the first magnet 211 and the second magnet 212, before the lower roller is installed on the connecting member 41, the side of the connecting member 41 close to the second support ear 22 is automatically offset downward, so that the mounting hole 411 of the connecting member 41 is in a state of being offset from top to bottom toward the second support ear 22, so that the roller shaft 31 can be more conveniently inserted into the mounting hole 411, which is more practical.

[0038] The hinge point between the connecting member 41 and the first support ear 21 is located on the side of the center of gravity of the connecting member 41 away from the second support ear 22 .

[0039] By setting the hinge point between the connecting member 41 and the first support ear 21 at a side away from the second support ear 22 relative to the center of gravity of the connecting member 41, the gravity of the connecting member 41 itself can be directly utilized to automatically deflect the connecting member 41 downward before installing the lower roller.

[0040] The support block 42 is laterally slidably mounted on the second ear 22; The side wall of the support block 42 close to the first support ear 21 is offset from top to bottom in a direction away from the first support ear 21; A sliding bolt 421 transversely passing through the second support ear 22 is threadedly connected to the support block 42 on one side away from the first support ear 21 , and a compression spring 422 is sleeved between the sliding bolt 421 and the second support ear 22 .

[0041] In fact, according to actual conditions, the support block 42 can be detachably installed on the second support ear 22 to achieve support for the free end of the roller shaft 31. In this embodiment, the support block 42 is installed by lateral sliding, and its side wall is tilted. When the free end of the roller shaft 31 is inserted into the notch 221 of the second support ear 22 by lifting upward, the free end of the roller shaft 31 can be used to push the inclined side wall in the opposite direction, so that the support block 42 is separated from the movement path of the roller shaft 31 until the end of the roller shaft 31 is separated from the support block 42, and the compression spring 422 drives the support block 42 to reset, thereby forming support for the free end of the roller shaft 31, which is easy to install and has strong practicality. When the lower roller needs to be disassembled, the sliding bolt 421 is pulled outward, or the supporting block 42 is pressed outward, which makes disassembly convenient.

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

[0043] The rotational freedom of the roller shaft 31 after installation is limited by the rotation limiting mechanism, so as to avoid the problem of wear of the first lug 21 and / or the second lug 22 due to the rotation of the roller shaft 31, and the practicability is strong.

[0044] The rotation limiting mechanism includes grooves 311 vertically opened on both sides of the roller shaft 31; The side walls of the notch 221 and the mounting hole 411 are both vertical planes; The groove 311 abuts against the corresponding vertical plane.

[0045] In fact, according to actual conditions, it is also possible to choose to open a strip positioning groove on the upper end surface of the roller shaft 31, and set corresponding positioning columns in the notch 221 and the mounting hole 411 to achieve the limitation of the rotational freedom of the roller shaft 31. This embodiment limits the rotational freedom of the roller shaft 31 by the mutual abutment of the groove 311 and the vertical plane. It has a simple structure, is easy to install, and is highly practical.

[0046] A first threaded hole 511 is formed on the first ear 21, and a through hole 512 is formed on the connecting member 41, and the through hole is connected to the mounting hole 411; A positioning hole 312 is axially opened at the end of the roller shaft 31; A first positioning bolt 51 is threadedly connected in the first threaded hole 511 , and the first positioning bolt 51 passes through the through hole and is arranged 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 the practicability is strong.

[0048] A second threaded hole 513 is formed on the second ear 22; A positioning hole 312 is axially opened at the end of the roller shaft 31; A second positioning bolt 52 is threadedly connected in the second threaded hole 513 , and the second positioning bolt 52 passes through the positioning hole 312 .

[0049] The second lug 22 and the roller shaft 31 are precisely positioned by the second positioning bolt 52, and a second vertical support for the roller shaft 31 is formed on the basis of the support block 42, thereby improving the installation accuracy of the roller body 3 relative to the second lug 22, and having strong practicality.

[0050] A conveyor belt comprises a roller body 3, two side plates 1, a belt body 10 located between the two side plates 1, and a lower roller mounting structure for the conveyor belt that is easy to disassemble and assemble; The first ear 21 and the second ear 22 are respectively mounted on a side plate 1; The roller body 3 is installed between the first support ear 21 and the second support ear 22 and is located below the belt body 10 .

[0051] In this embodiment, when the lower roller of the conveyor belt needs to be replaced, the second positioning bolt 52 is removed, the roller body 3 is supported by hand, and then the sliding bolt 421 is pulled outward, or the support block 42 is pressed outward to make way for the free end of the roller shaft 31 to move; With the hinge point between the connecting piece 41 and the first support ear 21 as the center, the free end of the roller body 3 is deflected downward until the roller shaft 31 is completely separated from the second support ear 22, and then the roller shaft 31 is pulled out from the mounting hole 411 of the connecting piece 41, and the lower roller can be disassembled; When the lower roller needs to be reinstalled, the roller body 3 is supported, and the roller body 3 is inserted from the bottom of the belt body 10 with the first ear 21 in a higher state, so that the roller shaft 31 enters the installation hole 411 under the guidance of the guide cylinder 412, and the first positioning bolt 51 is inserted into the positioning hole of the 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 support ear 22, so that the free end of the roller shaft 31 is pressed against the inclined side wall of the support block 42; Continue to lift upward, and use the free end of the roller shaft 31 to push the inclined side wall in the opposite direction, so that the support block 42 disengages from the movement path of the roller shaft 31, until the end of the roller shaft 31 disengages from the support block 42, and the compression spring 422 drives the support block 42 to reset, thereby forming support for the free end of the roller shaft 31, and finally screw the second positioning bolt 52 into the second threaded hole 513, so that the second positioning bolt 52 is inserted into the positioning hole 312 at the free end of the roller shaft 31.
