Description

Technical Field

[0001] The present invention relates to the technical field of roller structures of conveyor belts, in particular to a roller of a conveyor belt. Background Art

[0002] In conveyor belts, traditional roller structures rely primarily on simple rolling contact to achieve horizontal and vertical movement of goods. Inclined conveyors generally do not have forward and reverse motors. This is because inclined conveyor belts are designed primarily to efficiently transport materials from high to low locations. Such designs often prioritize directionality and continuity over frequent forward and reverse rotation. Forward and reverse motors are typically used in applications requiring frequent changes in conveying direction, such as sorting systems or bidirectional conveyor lines. Unless specifically required, inclined conveyors generally do not have forward and reverse motors, adding complexity and cost (including maintenance).

[0003] The existing roller is generally connected and fixed to the output shaft of the motor. The clockwise rotation of the motor drives the roller and the conveyor belt on the roller to rotate synchronously, so that the goods on the conveyor belt are transported to a lower place (car, ship); When goods are transported from a high place to a low place, if the weight of the goods is large, the conveyor belt automatically moves downward (without the need for the motor to actively reverse). At this time, the motor stops moving, but the output shaft of the motor will still rotate in the opposite direction with the roller (passive rotation). When the motor output shaft rotates passively (the motor output shaft idles), it is equivalent to applying a reverse load and mechanical wear to the motor, which affects the service life of the motor.

[0004] For this purpose, we propose a roller for a conveyor belt. Summary of the Invention

[0005] The object of the present invention is to provide a roller for a conveyor belt to solve the problems raised in the above background technology.

[0006] To achieve the above object, the present invention provides a roller for a conveyor belt, comprising two roller bodies that cooperate with the conveyor belt transmission, a connecting cylinder rotatably connected between the two roller bodies, a turntable rotatably connected to the ends of the roller bodies, and a side groove formed at the edge of the turntable; It also includes a roller located in the side groove and a movable plate that rotates with the roller. The roller is frictionally and rollingly engaged with the side groove and the drum body. A compression member is provided between the side groove and the movable plate. A limiting rod that penetrates the turntable is fixedly connected to the middle of the connecting tube. When the conveyor belt drives the goods to move downward automatically, the roller rotates and the turntable remains stationary; When the conveyor belt drives the goods downward under the action of the motor, the roller is clamped between the side groove and the drum body, and the turntable rotates.

[0007] Furthermore, the end of the movable plate is in a trapezoidal structure, and the turntable is provided with a sliding groove that slidably cooperates with the end of the movable plate.

[0008] Furthermore, the end of the movable plate is hinged with a rotating plate, a convex plate is rotatably connected in the turntable, the rotating plate movably passes through the convex plate, and the end of the rotating plate is pressed and fitted with a limiting rod.

[0009] Furthermore, an engaging ring is fixedly connected to the limiting rod, and a clamping plate clamped with the engaging ring is fixedly connected to the rotating plate.

[0010] Furthermore, the convex plate is snap-fitted with the engaging ring.

[0011] Furthermore, a connecting plate is fixedly connected to the connecting tube, and the connecting plate is fixedly connected to the limiting rod.

[0012] Furthermore, it also includes a fixed seat, the end of the roller body is fixedly connected to a limit ring that slides with the fixed seat, the fixed seat is provided with a sliding groove, a slider is slidably connected in the sliding groove, a threaded rod is threaded on the slider, and a pressure cylinder is movably sleeved on the outer surface of the threaded rod.

[0013] Furthermore, both sides of the slider are fixedly connected to the limiting cylinder, the pressing cylinder is located between the threaded rod and the pressing cylinder, and both ends of the threaded rod are fixedly connected to pressing blocks that press against the limiting cylinder, and the ends of the pressing blocks are truncated cone-shaped.

[0014] Furthermore, a rotating shaft is inserted and fixed in the middle of the turntable, and the ends of the rotating shaft are rotatably connected to mounting seats, and one of the rotating shafts is connected and fixed to the output shaft of the motor.

[0015] Furthermore, the fixing seat is connected and fixed to the limiting rod, a friction wheel is rotated on the connecting plate, and a friction groove for rolling friction with the friction wheel is provided on the outer surface of the end of the roller body.

[0016] Compared with the prior art, the present invention has the following beneficial effects: The turntable is connected to the drum body and can limit or allow the rotation of the drum body. Through the cooperation of the side groove and the roller, the drum body can be kept stable under the action of the gravity of the goods to prevent the motor from idling. The provision of a movable plate and compression member ensures that the turntable will not rotate counterclockwise when the weight of the cargo is high, effectively protecting the motor. The design of the friction wheel and friction groove ensures that when there is no external power, the rotation of one roller body can drive the synchronous rotation of the other roller body, thereby improving the overall efficiency of the system. The combination of the limit ring, slider, and pressure cylinder further stabilizes the position of the roller body and ensures the stability and reliability of the rotation. The friction wheel and friction groove structure enables the system to achieve smooth conveying through the weight of the cargo without motor drive, while ensuring the efficient operation of the motor and reducing unnecessary wear and energy consumption.

[0017] Under the action of the gravity of the goods, the conveyor belt drives the roller body to rotate. The movable plate and the roller cooperate through the side groove to prevent the turntable from rotating counterclockwise. The friction wheel and the friction groove ensure that the other roller body rotates synchronously. The limit ring and the slider further stabilize the position of the roller body, thereby achieving efficient and energy-saving conveying. BRIEF DESCRIPTION OF THE DRAWINGS

[0020] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0021] See also Figures 1-13 The present invention provides a roller for a conveyor belt, comprising two roller bodies 1 that cooperate with the conveyor belt transmission, a connecting tube 2 being rotatably connected between the two roller bodies 1 (the thickness of the connecting tube is set to be thinner than that of the roller bodies 1, the conveyor belt and the connecting tube do not contact each other, and the outer surface of the connecting tube is set to be smooth), a turntable 3 being rotatably connected to the end of the roller body 1, and a side groove 4 is opened on the edge of the turntable 3; A rotating shaft 23 is inserted and fixed in the middle of the turntable 3, and the ends of the rotating shaft 23 are rotatably connected to the mounting base 24, and one of the rotating shafts 23 is connected and fixed to the output shaft of the motor.

[0022] The two roller bodies 1 are butted together through the connecting tube 2. A connecting plate 14 (in a T-shaped structure) is fixedly connected to the connecting tube 2. The connecting plate 14 is connected and fixed to the limiting rod 8 and the fixing seat 15. The fixing seat 15 is connected and fixed to the limiting rod 8. The limiting rod 8, the fixing seat 15 and the connecting plate 14 restrict the two roller bodies 1 rotatably connected to the connecting tube to maintain coaxial distribution without affecting the rotation of the roller bodies 1 in their original positions. A friction wheel 25 rotates on the connecting plate 14, and a friction groove 26 is provided on the outer surface of the end of the roller body 1 for rolling friction with the friction wheel 25. The friction groove 26 does not contact the conveyor belt. When one of the roller bodies 1 rotates in its original position, it drives the friction wheel 25 on the connecting plate 14 to rotate, thereby causing the other roller body 1 to rotate synchronously. In this application, the friction wheel 25 can be replaced by a gear, and an external gear ring that meshes with the gear can be provided in the friction groove 26. The outer diameter of the external gear ring is smaller than the outer diameter of the roller body 1 to prevent the external gear ring from contacting the conveyor belt and damaging the conveyor belt. It is worth noting that the friction wheel 25 rotatably connected to the connecting plate 14 in the present application can also be arranged inside the connecting cylinder, and 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.

[0023] It also includes a roller 5 located in the side groove 4 and a movable plate 6 that rotates with the roller 5. The roller 5 is in frictional rolling cooperation with the side groove 4 and the drum body 1. A compression member 7 is provided between the side groove 4 and the movable plate 6. A limiting rod 8 that penetrates the turntable 3 is fixedly connected to the middle of the connecting tube 2. The end of the movable plate 6 is in a trapezoidal structure, and the turntable 3 is provided with a sliding groove 9 that is slidably matched with the end of the movable plate 6.

[0024] When the conveyor belt drives the goods to move downward automatically (the motor stops at this time, the weight of the goods is large, and the conveyor belt automatically drives downward), the conveyor belt drives the roller body 1 to rotate at its original position, and the inner wall of the rotating roller body 1 drives the roller 5 to rotate counterclockwise, and presses the movable plate 6 to move along the sliding groove 9, squeezing the compression member 7, and the turntable 3 remains stationary, thus ensuring that the output shaft of the motor does not rotate idly in the reverse direction; The end of the movable plate 6 is hinged with a rotating plate 10, and a convex plate 11 is rotatably connected to the turntable 3. The rotating plate 10 moves through the convex plate 11, and the end of the rotating plate 10 is pressed against the limit rod 8; when the movable plate 6 moves along the sliding groove 9 and squeezes the compression member 7, it drives the rotating plate 10 to rotate with the convex plate 11 as the rotation axis, and the rotating plate 10 slides adaptively along the convex plate 11, so that the end of the tilted rotating plate 10 is pressed against the limit rod 8 in the fixed position, thereby further reacting to fix the turntable 3, so that the turntable 3 remains stationary.

[0025] The motor starts and rotates. When the conveyor belt drives the goods downward under the action of the motor, the turntable 3 rotates counterclockwise, driving the roller 5 to make a circular motion. The roller 5 is located between the side groove 4 and the roller body 1. The roller 5 is stuck between the side groove 4 and the roller body 1, and the compression member 7 is relaxed. The turntable 3 that makes a circular motion drives the roller body 1 to rotate counterclockwise synchronously, which is convenient for conveying the light goods on the conveyor belt down. The compression member 7 is relaxed, so that the rotating plate 10 is away from the limiting rod 8 , thereby releasing the restriction on the turntable 3 and ensuring the rotation of the turntable 3 .

[0026] An engaging ring 12 is fixedly connected to the limit rod 8, and a clamping plate 13 that is clamped with the engaging ring 12 is fixedly connected to the rotating plate 10. Through the cooperation between the clamping plate 13 and the engaging ring 12, when the rotating plate 10 contacts the limit rod 8, the turntable 3 is further kept stable and does not rotate.

[0027] Furthermore, the convex plate 11 is engaged with the meshing ring 12 , and the rotation of the convex plate 11 presses the meshing ring 12 , thereby enhancing the stability of the turntable 3 so as to keep it stable and not rotate.

[0028] The end of the drum body 1 is fixedly connected to a limiting ring 16 that slides with the fixing seat 15. The fixing seat 15 is provided with a sliding groove 17. A slider 18 is slidably connected to the sliding groove 17. The slider 18 is threaded with a threaded rod 19. The outer surface of the threaded rod 19 is movably sleeved with a pressure cylinder 20. The sliding cooperation between the limiting ring 16 and the fixing seat 15 further ensures the stability of the original position rotation of the drum body 1. Furthermore, by sliding the slider 18 along the slide groove 17 , the pressing cylinder 20 on the threaded rod 19 contacts the limiting ring 16 , further ensuring that the limiting ring 16 and the drum body 1 rotate in their original positions.

[0029] Both sides of the slider 18 are fixedly connected to the limit cylinder 21, and the pressing cylinder 20 is located between the threaded rod 19 and the pressing cylinder 20. The two ends of the threaded rod 19 are fixedly connected to the pressing blocks 22 that press against the limit cylinder 21. The ends of the pressing blocks 22 are truncated cone-shaped. After the pressing cylinder 20 contacts the limiting ring 16, the threaded rod 19 rotates, causing the two sliders 18 to move away from each other (the threads of the two sliders 18 are distributed in opposite directions, thereby ensuring that the two sliders 18 move away from each other). The sliders 18 drive the limiting cylinder 21 to move, and the outer sides of the two sliders 18 tightly press against the sides of the chute 17, thereby fixing the positions of the sliders 18 and the pressing cylinder 20. Furthermore, the limiting cylinder 21 moves to press the end of the pressing block 22 , thereby enhancing the stability between the slider 18 and the fixing seat 15 .
