Description

Technical Field

[0001] The invention relates to the technical field of conveyor belt disassembly and assembly, and in particular to a can conveyor belt disassembly and assembly device and a disassembly and assembly method. Background Art

[0002] During the production process of cans, conveyor belts are required for transportation. Conveyor belts are usually set horizontally. At the same time, since the can conveyor belt is formed by hingedly connecting multiple groups of conveyor belt units with the same structure, and driven by a driving wheel and tensioned by a tensioning roller, the conveying stability of the conveyor belt is ensured to prevent tooth slippage. However, during the use of the conveyor belt, it is inevitable that the conveyor belt will be damaged or worn, and the conveyor belt needs to be maintained. At this time, the conveyor belt needs to be disassembled and assembled.

[0003] During the actual disassembly and assembly process of the conveyor belt, it was found that it was necessary to open the driving wheel protective cover and release the tensioning roller, then remove the driving wheel, and possibly remove the guide rail before the conveyor belt can be disassembled and assembled. The operation was too troublesome. In actual production, it was found that during partial disassembly, the conveyor belt could be tightened to a certain degree and maintained for a period of time, and two smaller screwdrivers or awls could be used by hand to insert them into the gaps or holes in the conveyor belt and tighten them in opposite directions. However, this method tests the arm strength of the staff and is quite strenuous. Alternatively, the staff can stand on the conveyor belt and manually reverse the motor to tighten the conveyor belt, but this method poses a safety hazard.

[0004] The above two methods used in production practice have defects such as instability, low efficiency, unsafety, and prone to accidents. Therefore, the present invention solves the above problems through a can conveyor belt disassembly and assembly device and a disassembly and assembly method. Summary of the invention

[0007] Preferably, the limiting tooth claw is configured as a first claw unit, the track is arranged along the width direction of the mounting plate, and the first claw units are four groups, and each group of first claw units is arranged perpendicular to the mounting plate.

[0011] Preferably, it also includes an anti-slip assembly mounted on the mounting plate, wherein the anti-slip assembly is connected to each group of second claw tooth units.

[0012] Preferably, the anti-slip assembly includes a receiving groove opened on the mounting plate, a pull plate is slidably installed in the receiving groove, a connecting column is fixed on the top of the pull plate, and the number of the connecting columns is the same as the number of the second claw tooth units, a tensioning rope is fixedly connected to each group of connecting columns, and the other end of each group of tensioning ropes passes through the corresponding second claw tooth unit and is connected to the top of the moving claw.

[0013] Preferably, the connecting column and the second claw unit correspond one to one, and the end of the tensioning rope passes through the second threaded column, the second sliding seat, and the fixed claw from top to bottom in sequence and is connected to the hanging seat.

[0014] Preferably, the opposite side walls of the fixed claw and the movable claw are both inclined and horn-shaped, and the hanging seat is located on a side close to the tensioning ratchet body.

[0015] The present invention also discloses a method for disassembling and assembling a can conveyor belt, and the specific steps are as follows: S1: When disassembling the conveyor belt, first adjust the first hook unit and the second hook unit accordingly, that is, manually loosen the second fastening nut, then adjust the position of the second claw unit according to the hole spacing on the conveyor belt, and then tighten the second fastening nut so that the distance between two adjacent groups of second claw units is the same as the distance between two adjacent holes on the conveyor belt; S2: inserting the adjusted second claw unit on both sides of the conveyor belt unit to be disassembled, that is, installing the first claw unit and the second claw unit on two groups of conveyor belt units adjacent to the conveyor belt unit to be disassembled, respectively, to isolate the conveyor belt unit to be disassembled; S3: Operate the tensioning ratchet body so that the dynamic tensioning belt is gradually wound on the tensioning ratchet body.

When the first claw unit slides in the track, the anti-flipping effect of the first claw unit is guaranteed. In this way, the tightening operation of the conveyor belt can be easily achieved by tightening the ratchet body, which facilitates the disassembly and assembly of the conveyor belt and reduces the difficulty of disassembly and assembly of the conveyor belt.

[0017] 2. The present invention optimizes the limiting tooth claw as the second claw tooth unit, and cooperates with the use of the anti-slip assembly.

DETAILED DESCRIPTION

[0020] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0021] Embodiment 1: like Figures 1 to 3 As shown, the present embodiment discloses a can conveyor belt disassembly and assembly device, comprising a tensioning ratchet body 1, on which a fixed tensioning belt 2 is fixedly sleeved, on which a dynamic tensioning belt 3 is wound and assembled, and on which a first hook unit 4 is mounted on the other end of the fixed tensioning belt 2, and on which a second hook unit 5 is mounted on the other end of the dynamic tensioning belt 3, and the second hook unit 5 has the same structural composition as the first hook unit 4. When in use, only the first hook unit 4 and the second hook unit 5 need to be inserted into the gap on the conveyor belt, and then the tensioning ratchet body 1 can be reciprocated to tighten the dynamic tensioning belt 3, and then the first hook unit 4 and the second hook unit 5 can be used to tighten the conveyor belt, thereby facilitating the disassembly and assembly of the conveyor belt.

[0022] See also Figure 3The second hook claw unit 5 includes a mounting plate 7, a track 8 is provided on the mounting plate 7, and multiple groups of limiting claws with the same structure are installed in the track 8. The limiting claws are arranged as first claw units 6. The track 8 is arranged along the width direction of the mounting plate 7, and there are four groups of first claw units 6. Each group of first claw units 6 is arranged perpendicular to the mounting plate 7, and the limiting claws are inserted into the gaps on the conveyor belt, which can well realize the limiting property between the disassembly and assembly device and the conveyor belt.

[0023] See also Figure 3 The first claw unit 6 includes a first slide seat 61 slidably assembled in the track 8, a first hook body 62 is fixedly installed at the bottom of the first slide seat 61, a first threaded column 63 is fixed at the top of the first slide seat 61, a first fastening nut 64 is threadedly connected to the first threaded column 63, and the first fastening nut 64 is attached to the top of the mounting plate 7.

[0024] When in use, the first claw unit 6 can be moved in the track 8, that is, the first slide seat 61 is moved, which can drive the first hook claw body 62 to move synchronously, so as to facilitate the adjustment of the distance between the two adjacent groups of first claw units 6, so as to match the distance between the gaps on the conveyor belt and improve the adaptability. When the first claw unit 6 slides in the track 8, the anti-flip effect of the first claw unit 6 is guaranteed. In this way, the tightening operation of the conveyor belt can be easily achieved by tightening the ratchet body 1, so that the disassembly and assembly of the conveyor belt can be completed conveniently.

[0025] Embodiment 2: During the use of Example 1, it was found that: since the conveyor belt is formed by hingedly connecting multiple groups of conveyor belt units with the same structure, when the two separated groups of conveyor belt units are tightened by the disassembly and assembly device, the tightening effect can be achieved, but the conveyor belt cannot be disassembled and assembled if the tension is not enough. However, once the tension is too high, since the limit tooth claw is perpendicular to the conveyor belt, it is easy for the conveyor belt unit at the position of the limit tooth claw to deflect during the continuous tightening of the conveyor belt. In this way, during the continuous operation of the tensioning ratchet body 1 to tighten the conveyor belt unit, the limit tooth claw will fall off from the pores on the conveyor belt unit, resulting in the failure of the conveyor belt tightening operation. If the limit tooth claw is designed to be curved or hook-shaped, it is difficult to install the limit tooth claw in the pores on the conveyor belt, and the operation is more troublesome. Based on this, the present embodiment optimizes and improves the limit tooth claw, specifically as follows: See also Figure 4-Figure 7 The limiting tooth claw is set as a second claw unit 9, and the second claw unit 9 is divided into four groups. Each group of second claw units 9 is vertically arranged on the mounting plate 7. The second claw unit 9 can also be moved in the track 8, which is convenient for real-time adjustment according to the distance between the gaps on the conveyor belt.

[0026] See also Figure 7The second claw unit 9 includes a second slide 91 slidably assembled in the track 8, a fixed claw 92 is fixedly installed at the bottom of the second slide 91, a second threaded column 93 is fixed on the top of the second slide 91, a second fastening nut 94 is threadedly connected to the second threaded column 93, and the second fastening nut 94 is attached to the top of the mounting plate 7. The operation method is the same as that of the first claw unit 6 in Example 1, and the position adjustment and fixation of the second claw unit 9 can be easily completed.

[0027] It is worth noting that a movable claw 96 is hingedly installed on the outer bottom side of the fixed claw 92 through a hinged shaft sleeve 95, and a hanging seat 97 is fixed on the top of the movable claw 96. The opposite side walls of the fixed claw 92 and the movable claw 96 are both inclined and trumpet-shaped. The hanging seat 97 is located on the side close to the tensioning ratchet body 1, and also includes an anti-slip assembly 10 installed on the mounting plate 7. The anti-slip assembly 10 is connected to each group of second claw tooth units 9. In this way, the first hook claw body 62 in Example 1 is split into a hinged fixed claw 92 and a movable claw 96, which can drive the anti-slip assembly 10 to move during the process of tightening the conveyor belt, so that it drives the movable claw 96 to flip relative to the fixed claw 92, thereby completing the self-locking of the conveyor belt.

[0028] Please refer to 5- Figure 7 The anti-slip assembly 10 includes a receiving groove 105 opened on the mounting plate 7, and a pull plate 101 is slidably installed in the receiving groove 105. A slider 104 is arranged on the side wall of the pull plate 101, and a slide groove is opened on the inner wall of the receiving groove 105, which is convenient for the slider 104 to slide in the slide groove, thereby ensuring the stability of the pull plate 101 when sliding in the receiving groove 105. A connecting column 102 is fixed on the top of the pull plate 101, and the number of the connecting columns 102 is the same as the number of the second claw tooth units 9. A tensioning rope 103 is fixedly connected to each group of connecting columns 102, and the other end of each group of tensioning ropes 103 passes through the corresponding second claw tooth unit 9 and is connected to the top of the movable claw 96. The connecting column 102 and the second claw tooth unit 9 correspond one to one, and the end of the tensioning rope 103 passes through the second threaded column 93, the second slide seat 91, and the fixed claw 92 from top to bottom in sequence and is connected to the hanging seat 97.

[0029] In actual use, after the corresponding adjustment of the distance between the first hook unit 4 and the second hook unit 5 and the gap on the conveyor belt is completed, the first hook unit 4 and the second hook unit 5 are inserted into the separated conveyor belt units, and then the tensioning ratchet body 1 is operated to cause the dynamic tensioning belt 3 to be gradually wound on the tensioning ratchet body 1. At this time, the conveyor belt is gradually tightened and maintained. At the same time, the dynamic tensioning belt 3 will continue to generate tension on the pulling plate 101, causing the pulling plate 101 to move in the receiving groove 105, and the mounting plate 7 and the limiting tooth claw are limited on the conveyor belt, so the pulling plate 101 will pull the tensioning rope 103 to move, and then the moving claw 96 is driven by the pulling action of the tensioning rope 103 to rotate around the hinge sleeve 95 towards the direction close to the fixed claw 92, so that an obtuse angle is formed between the fixed claw 92 and the moving claw 96, that is, a barb shape is formed, which can realize the self-locking of the conveyor belt by the limiting tooth claw during the process of tightening the conveyor belt, greatly improve the installation limit degree of the disassembly and assembly device on the conveyor belt, prevent self-detachment, and improve the safety of use.

[0030] It should be noted that when there is no tensioning force on the dynamic tensioning belt 3, there is naturally no tension on the tensioning plate 101. At this time, the tensioning rope 103 will not have a pulling force on the movable claw 96. At this time, the movable claw 96 is in a vertical state, which is convenient for the limiting tooth claw to detach from the gap on the conveyor belt. The operation is convenient and safe.

[0031] Embodiment 3: This embodiment discloses a method for disassembling and assembling a can conveyor belt, and the specific steps are as follows: S1: When the conveyor belt is disassembled, the first hook unit 4 and the second hook unit 5 are first adjusted accordingly, that is, the second fastening nut 94 is manually loosened, and then the position of the second claw unit 9 is adjusted according to the hole spacing on the conveyor belt, and then the second fastening nut 94 is tightened, so that the distance between two adjacent groups of second claw units 9 is the same as the distance between two adjacent holes on the conveyor belt; S2: inserting the adjusted second claw unit 9 on both sides of the conveyor belt unit to be disassembled, that is, installing the first hook unit 4 and the second hook unit 5 on two groups of conveyor belt units adjacent to the conveyor belt unit to be disassembled, respectively, to isolate the conveyor belt unit to be disassembled; S3: Operate the tensioning ratchet body 1 so that the movable tensioning belt 3 is gradually wound on the tensioning ratchet body 1. At this time, the conveyor belt is gradually tightened and maintained. During the tightening process of the conveyor belt, the tensioning belt pulls the movable claw 96 through the anti-slip assembly 10, so that an obtuse angle is formed between the movable claw 96 and the fixed claw 92, ensuring that the movable claw 96 is stuck in the gap of the conveyor belt and does not fall off during tightening. After the conveyor belt is tightened, the conveyor belt unit to be disassembled becomes loose, and the staff can remove the conveyor belt unit to be disassembled, and then remove the remaining conveyor belt units in turn; S4: When installing the conveyor belt, connect the conveyor belt units in sequence and install them on the conveyor drive wheel. When installing the last set of conveyor belt units, follow the above steps and use the disassembly and assembly device to keep the last two sets of conveyor belt units in a tensioned state. Then install the last set of conveyor belt units on the last two sets of conveyor belt units. Loosen the tensioning ratchet body 1 to complete the installation.

[0032] Finally, it should be noted that the above are only preferred embodiments of the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, it is still possible for those skilled in the art to modify the technical solutions described in the aforementioned embodiments, or to make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
