Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of roller structure of conveying belt, in particular to a roller of conveying belt. BACKGROUND

[0002] In the conveying belt equipment, the traditional roller structure mainly relies on simple rolling contact to realize the movement of goods in horizontal and vertical directions, and the inclined conveying device is generally not provided with a forward and reverse motor, because in the design of the inclined conveying device, the main consideration is how to effectively convey the materials from high to low, and such design often focuses more on the directionality and continuity of conveying, rather than frequent forward and reverse rotation, and the forward and reverse motor is usually used in application scenarios that need to frequently change the conveying direction, such as sorting systems or bidirectional conveying lines. In the inclined conveying device, unless there is a special requirement, a forward and reverse motor is generally not provided to increase complexity and cost (including maintenance cost).

[0003] The existing roller is generally fixedly connected with the output shaft of the motor, and through the clockwise rotation of the motor, the roller and the conveying belt on the roller are driven to rotate synchronously, so as to carry the goods on the conveying belt to a low place (a vehicle or a ship);

[0004] When the goods are conveyed from high to low, the conveying belt automatically moves downward (without the need for active reverse rotation of the motor) when the gravity of the goods is large, at which time the motor stops moving, but the output shaft of the motor reversely rotates (passively rotates) with the roller, and when the output shaft of the motor passively rotates (the output shaft of the motor idles), a reverse load is applied to the motor and mechanical wear is caused, which affects the service life of the motor.

[0005] Therefore, the present application provides a roller of conveying belt. SUMMARY

[0006] The present application aims to provide a roller of conveying belt to solve the problems in the background.

[0007] To achieve the above-mentioned purpose, the present application provides a roller of conveying belt, comprising two roller bodies in driving cooperation with the conveying belt, and a communication cylinder rotatably connected between the two roller bodies, wherein the end of each roller body is rotatably connected with a rotating disc, and a side groove is formed at the edge of the rotating disc;

[0008] Further comprising a rolling disc located in the side groove and a movable plate in driving cooperation with the rolling disc, wherein the rolling disc is in frictional rolling cooperation with the side groove and the roller body, a compression member is arranged between the side groove and the movable plate, and a limiting rod penetrating the rotating disc is fixedly connected to the middle part of the communication cylinder;

[0009] When the conveying belt drives the goods to automatically move downward, the rolling disc rotates and the rotating disc remains stationary;

[0010] When the conveying belt is driven by the motor to move the goods downwards, the rolling disc is clamped between the side groove and the roller body, and the rotating disc rotates.

[0011] Further, the end of the movable plate is in a trapezoidal structure, and the rotating disc is provided with a sliding groove in sliding fit with the end of the movable plate.

[0012] Further, the end of the movable plate is hingedly connected with a rotating plate, the rotating disc is rotatably connected with a convex plate, the rotating plate movably penetrates through the convex plate, and the end of the rotating plate is in abutting fit with the limiting rod.

[0013] Further, the limiting rod is fixedly connected with an engaging ring, and the rotating plate is fixedly connected with a clamping plate in clamping fit with the engaging ring.

[0014] Further, the convex plate is in clamping fit with the engaging ring.

[0015] Further, the connecting tube is fixedly connected with a connecting plate, and the connecting plate is fixedly connected with the limiting rod.

[0016] Further, the fixed seat is further provided, the roller body is fixedly connected with a limiting ring in sliding fit with the fixed seat, the fixed seat is provided with a sliding groove, the sliding groove is slidably connected with a sliding block, the sliding block is threadedly provided with a threaded rod, and the outer surface of the threaded rod movably sleeved with an abutting tube.

[0017] Further, the sliding block is fixedly connected with a limiting tube on both sides, the abutting tube is located between the threaded rod and the abutting tube, the threaded rod is fixedly connected with an abutting block in abutting fit with the limiting tube on both ends, and the end of the abutting block is in a circular truncated cone shape.

[0018] Further, the rotating disc is fixedly connected with a rotating shaft in the middle, the rotating shaft is rotatably connected with a mounting seat on the end, and one of the rotating shafts is fixedly connected with the output shaft of the motor.

[0019] Further, the fixed seat is fixedly connected with the limiting rod, the connecting plate is self-rotatably provided with a friction wheel, and the outer surface of the end of the roller body is provided with a friction groove in rolling friction with the friction wheel.

[0020] Compared with the prior art, the beneficial effects of the present application are:

[0021] The rotating disc is connected with the roller body, and can limit or allow the self-rotation of the roller body, the cooperation of the side groove and the rolling disc can keep the roller body stable under the action of the gravity of the goods, and avoid the motor idling;

[0022] The setting of the movable plate and the compression part ensures that the rotating disc does not rotate counterclockwise when the gravity of the goods is large, effectively protecting the motor, the friction wheel and the friction groove design, ensuring that the rotation of one drum body can drive the synchronous rotation of another drum body without external power, thereby improving the overall efficiency of the system. The cooperation of the limiting ring, the sliding block and the pressing cylinder further stabilizes the position of the drum body, ensuring the stability and reliability of the rotation. The friction wheel and the friction groove structure enable the system to realize stable conveying without motor driving through the gravity of the goods, while ensuring the efficient operation of the motor, reducing unnecessary wear and energy consumption.

[0023] Under the action of the gravity of the goods, the conveying belt drives the drum body to rotate, the movable plate and the rolling disc cooperate through the side groove to prevent the rotating disc from rotating counterclockwise, the friction wheel and the friction groove ensure the synchronous rotation of the other drum body, and the limiting ring and the sliding block further stabilize the position of the drum body, thereby realizing efficient and energy-saving conveying effect.

DETAILED DESCRIPTION

[0038] The technical solutions in the embodiments of the application will be clearly and completely described below with reference to the drawings in the embodiments of the application. Obviously, the described embodiments are only part of the embodiments of the application, rather than all the embodiments of the application. Based on the embodiments in the application, all other embodiments obtained by a person of ordinary skill in the art without creative work fall within the protection scope of the application.

[0039] Please refer to Figures 1-13 The application provides a roller for a conveying belt, which comprises two roller bodies 1 that are in transmission cooperation with the conveying belt, a communication cylinder 2 that is rotatably connected between the two roller bodies 1 (the thickness of the communication cylinder is set to be thinner than the roller body 1, the conveying belt does not contact the communication cylinder, and the outer surface of the communication cylinder is smooth), a rotating disc 3 that is rotatably connected to the end of the roller body 1, and a side groove 4 that is formed at the edge of the rotating disc 3.

[0040] A rotating shaft 23 is inserted and fixed in the middle of the rotating disc 3, and a mounting seat 24 is rotatably connected to the end of the rotating shaft 23. One of the rotating shafts 23 is fixedly connected with the output shaft of a motor.

[0041] The two roller bodies 1 are positioned and connected through the communication cylinder 2. The communication cylinder 2 is fixedly connected with a connecting plate 14 (in a T-shaped structure), the connecting plate 14 is fixedly connected with the limiting rod 8 and the fixed seat 15, the fixed seat 15 is fixedly connected with the limiting rod 8, and the limiting rod 8, the fixed seat 15 and the connecting plate 14 limit the two roller bodies 1 that are rotatably connected to the communication cylinder to be coaxially distributed, and do not affect the original rotation of the roller body 1.

[0042] The connecting plate 14 is provided with a friction wheel 25 rotating with the connecting plate 14, and the outer surface of the end of the drum body 1 is provided with a friction groove 26 for rolling friction with the friction wheel 25, and the friction groove 26 does not contact the conveying belt. When one of the drum bodies 1 rotates at the original position, the friction wheel 25 on the connecting plate 14 rotates, thereby synchronously rotating the other drum body 1. In the present application, the friction wheel 25 can be replaced by a gear, and the friction groove 26 can be provided with an external gear ring meshing with the gear. The outer diameter of the external gear ring is smaller than the outer diameter of the drum body 1, so as to avoid the external gear ring contacting the conveying belt and damaging the conveying belt.

[0043] It is worth noting that the friction wheel 25 rotatingly connected with the connecting plate 14 in the present application can also be arranged inside the connecting cylinder. The inner surface of the end of the drum body 1 is provided with a friction groove 26 for rolling friction with the friction wheel 25.

[0044] Further comprising a rolling disc 5 located in the edge groove 4 and a movable plate 6 rotatingly matched with the rolling disc 5. The rolling disc 5 is rollingly matched with the edge groove 4 and the drum body 1. The edge groove 4 is provided with a compression member 7 between the edge groove 4 and the movable plate 6. The connecting cylinder 2 is fixedly connected with a limiting rod 8 penetrating the rotating disc 3.

[0045] The end of the movable plate 6 is in a trapezoidal structure, and the rotating disc 3 is provided with a sliding groove 9 slidingly matched with the end of the movable plate 6.

[0046] When the conveying belt automatically moves downward (at this time, the motor stops moving, the weight of the goods is large, and the conveying belt automatically drives downward), the conveying belt drives the drum body 1 to rotate at the original position. The inner wall of the drum body 1 rotating at the original position drives the rolling disc 5 to rotate counterclockwise, and the rolling disc 5 presses the movable plate 6 to move along the sliding groove 9, thereby extruding the compression member 7. The rotating disc 3 remains stationary, thereby ensuring that the output shaft of the motor does not reverse and idle.

[0047] The end of the movable plate 6 is hingedly connected with a rotating plate 10, and the rotating disc 3 is rotatingly connected with a convex plate 11. The rotating plate 10 movably penetrates the convex plate 11, and the end of the rotating plate 10 is abuttingly matched with the limiting rod 8. When the movable plate 6 moves along the sliding groove 9 and extrudes the compression member 7, the rotating plate 10 rotates about the convex plate 11 as the rotating shaft, and the rotating plate 10 adaptively slides along the convex plate 11, thereby making the end of the rotating plate 10 abuttingly located on the limiting rod 8 at the fixed position, thereby further reacting to fix the rotating disc 3, so as to keep the rotating disc 3 stationary.

[0048] When the motor is started, the rotating disc 3 rotates counterclockwise when the conveying belt moves downward under the action of the motor, thereby driving the rolling disc 5 to make a circular motion. The rolling disc 5 is located between the edge groove 4 and the drum body 1, and the rolling disc 5 is clamped between the edge groove 4 and the drum body 1. The compression member 7 is relaxed, and the rotating disc 3 driving the drum body 1 to synchronously rotate counterclockwise facilitates conveying the goods with small weight on the conveying belt downward.

[0049] Wherein, the compression piece 7 relaxes, the rotating plate 10 is away from the limiting rod 8, the restriction to the rotating disc 3 is released, and the rotation of the rotating disc 3 is ensured.

[0050] The limiting rod 8 is fixedly connected with an engaging ring 12, and the rotating plate 10 is fixedly connected with a clamping plate 13 clamped with the engaging ring 12, so that the rotating plate 10 contacts the limiting rod 8, and the rotating disc 3 is further kept stable and non-rotating.

[0051] Further, the convex plate 11 is clamped with the engaging ring 12, and the rotating disc 3 is kept stable and non-rotating by the rotation of the convex plate 11 and the pressing of the engaging ring 12.

[0052] The end of the drum body 1 is fixedly connected with a limiting ring 16 in sliding cooperation with a fixed seat 15, the fixed seat 15 is provided with a sliding groove 17, the sliding groove 17 is slidably connected with a sliding block 18, the sliding block 18 is screwed with a threaded rod 19, the threaded rod 19 is movably sleeved with a pressing cylinder 20, and the sliding cooperation of the limiting ring 16 and the fixed seat 15 further ensures the stability of the original position of the drum body 1.

[0053] Further, the sliding block 18 is slid along the sliding groove 17, so that the pressing cylinder 20 on the threaded rod 19 contacts the limiting ring 16, and the original position of the limiting ring 16 and the drum body 1 is further ensured.

[0054] The sliding block 18 is fixedly connected with a limiting cylinder 21 on both sides, the pressing cylinder 20 is located between the threaded rod 19 and the pressing cylinder 20, the threaded rod 19 is fixedly connected with a pressing block 22 in pressing cooperation with the limiting cylinder 21 at both ends, and the end of the pressing block 22 is in the shape of a circular truncated cone.

[0055] After the pressing cylinder 20 contacts the limiting ring 16, the self-rotating threaded rod 19 makes the two sliding blocks 18 move away from each other (the threaded directions of the two sliding blocks 18 are opposite, so that the two sliding blocks 18 move away from each other), the sliding block 18 drives the limiting cylinder 21 to move, and the outer sides of the two sliding blocks 18 are tightly pressed against the side of the sliding groove 17, so as to fix the positions of the sliding block 18 and the pressing cylinder 20.

[0056] Further, the limiting cylinder 21 moves and presses the end of the pressing block 22, so as to enhance the stability between the sliding block 18 and the fixed seat 15.
