Description

Technical Field

[0001] This utility model relates to the field of conveyor belt technology, specifically a braking and limiting device for a conveyor belt. Background Technology

[0002] In modern industrial production and logistics, conveyor belts are widely used as important material conveying equipment on various production lines for the continuous and efficient transport of various goods, such as food, pharmaceuticals, and spare parts. With their advantages of large conveying capacity, simple structure, and convenient maintenance, conveyor belts play an indispensable role in many industries.

[0003] During the operation of conveyor belts, situations often arise requiring an emergency stop. Typically, this is achieved by de-energizing the motor and allowing the equipment to gradually stop due to its own friction. However, relying solely on friction for braking results in a slow braking process, preventing the conveyor belt from stopping quickly. In emergency braking scenarios, this inability to respond promptly may cause goods to continue moving, increasing the risk of collision damage. When goods deviate to the edge of the conveyor belt, they can easily fall off, making it difficult to adjust their position. Therefore, this invention provides a braking and limiting device for conveyor belts. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a braking and limiting device for conveyor belts. This solves the problem that during the operation of conveyor belts, situations often require emergency stops. Typically, braking relies on the frictional force of the equipment itself after the motor is powered off, which is slow and prevents the conveyor belt from stopping quickly. In emergency braking scenarios, this inability to respond promptly may cause goods to continue moving, increasing the risk of collision damage. Furthermore, when goods deviate to the edge of the conveyor belt, they can easily fall off, making it difficult to adjust their position on the belt.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a braking and limiting device for a transport belt, comprising a support frame, wherein a conveying mechanism for the transport belt equipment is provided on the support frame, and the conveying mechanism includes:

[0006] The braking assembly includes a support housing fixed to the upper end of a support frame, a support shaft rotatably connected through the inside of the support housing, a positioning tooth fixed to one end of the support shaft, a positioning wheel fixed to the side wall of the support frame, and a positioning block connected by an elastic component inside the positioning wheel.

[0007] The limiting component includes a mounting bracket that supports the fixing of the side wall of the housing, and a sliding bracket is slidably connected inside the mounting bracket, with a limiting bracket fixed at one end of the sliding bracket.

[0008] Preferably, a motor is provided on the inner side of the support frame, a chain wheel is provided at the output end of the motor, and a chain body is provided on the outer side of the chain wheel. A chain wheel connected to the chain body is fixed on the outer wall of the support shaft, and a roller body is fixed at one end of the support shaft. A conveyor belt body is provided on the outer wall of the roller body.

[0009] Preferably, the positioning wheel has a cavity groove inside, the inner wall of the cavity groove is provided with a spring, the positioning block is located at the other end of the spring, and a connecting shaft is fixed to the inner wall of the cavity groove, and the other end of the positioning block is rotatably connected to the connecting shaft.

[0010] Preferably, the outer wall of the positioning tooth is provided with a tooth groove, and one end of the positioning block is engaged with the tooth groove.

[0011] Preferably, the side wall of the mounting bracket is rotatably connected to a screw, the side wall of the sliding bracket is fixed with a connecting plate, and the screws are threaded together.

[0012] Preferably, the limiting bracket has an L-shaped structure, and rotatable sliding shafts are evenly arranged inside the limiting bracket.

[0013] Beneficial effects

[0014] This invention provides a braking and limiting device for a transport conveyor belt. Compared with the prior art, it has the following advantages:

[0015] Firstly, the positioning teeth of this utility model rotate synchronously with the support shaft, and the positioning block is tightly attached to the surface of the positioning teeth under the action of the spring. When an emergency stop is required, the motor is powered off, the support shaft decelerates, and the positioning block is engaged in the tooth groove due to the spring thrust. The self-locking structure is formed by the rotation of the connecting shaft, preventing the support shaft from continuing to rotate. The engaging structure between the positioning block and the positioning teeth can effectively prevent the support shaft from rotating, quickly stop the main body of the conveyor belt, prevent the conveyor belt from continuing to move due to inertia, and reduce the risk of collision damage and slippage of goods.

[0016] Secondly, the screw on the side wall of the rotating mounting bracket of this utility model is threadedly connected to the connecting plate fixed to the side wall of the sliding bracket. The rotation of the screw drives the sliding bracket to slide inside the mounting bracket, thereby driving the limit bracket to move and adjust the position of the limit bracket to prevent the transported goods from deviating on both sides and reduce the material falling off due to the mesh belt running off track. When the main body of the transport mesh belt is running, if the item deviates, it will contact the rotatable sliding shaft inside the limit bracket. The rotatable design of the sliding shaft can reduce the friction between it and the goods. Moreover, the limit brackets are independently set on both sides of the transport mesh belt and can be adjusted individually to control the position of the transported items on the mesh belt. The overall operation is simple and convenient. Attached Figure Description

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Please see Figures 1-4 This utility model provides a technical solution: a braking and limiting device for a transport mesh belt, including a support frame 1, on which a conveying mechanism for the transport mesh belt equipment is provided, the conveying mechanism including:

[0024] The braking assembly includes a support housing 2 fixed to the upper end of a support frame 1, a support shaft 201 rotatably connected through the inside of the support housing 2, a positioning tooth 302 fixed to one end of the support shaft 201, a positioning wheel 3 fixed to the side wall of the support frame 1, and a positioning block 305 connected by an elastic component inside the positioning wheel 3.

[0025] The limiting component includes a mounting bracket 5 that supports the side wall of the housing 2 for fixing, and a sliding bracket 6 that is slidably connected inside the mounting bracket 5. One end of the sliding bracket 6 is fixed with a limiting bracket 601.

[0026] In a preferred embodiment, a motor 4 is provided on the inner side of the support frame 1, a chain wheel is provided at the output end of the motor 4, and a chain body 401 is provided on the outer side of the chain wheel. A chain wheel connected to the chain body 401 is fixed on the outer wall of the support shaft 201, and a roller body 202 is fixed at one end of the support shaft 201. A conveyor belt body 203 is provided on the outer wall of the roller body 202. A cavity groove 301 is opened inside the positioning wheel 3. A spring 306 is provided on the inner wall of the cavity groove 301. A positioning block 305 is located at the other end of the spring 306. A connecting shaft 304 is fixed on the inner wall of the cavity groove 301, and the other end of the positioning block 305 is rotatably connected to the connecting shaft 304. A tooth groove 303 is opened on the outer wall of the positioning tooth 302, and one end of the positioning block 305 is engaged with the tooth groove 303.

[0027] When the motor 4 starts, the chain wheel at its output end drives the chain wheel on the outer wall of the support shaft 201 to rotate through the chain body 401, thereby causing the support shaft 201 to rotate. The roller body 202 fixed at one end of the support shaft 201 rotates synchronously, thereby driving the conveyor belt body 203 to run.

[0028] Furthermore, the positioning teeth 302 rotate synchronously with the support shaft 201, and the positioning block 305 is tightly attached to the surface of the positioning teeth 302 under the action of the spring 306. When an emergency stop is required, the motor 4 is de-energized, the support shaft 201 decelerates, and the positioning block 305 is engaged in the tooth groove 303 due to the thrust of the spring 306. Through the rotational connection of the connecting shaft 304, a self-locking mechanism is formed, preventing the support shaft 201 from continuing to rotate. The engaging structure between the positioning block 305 and the positioning teeth 302 can effectively prevent the support shaft 201 from rotating, quickly stop the transport belt body 203 from running, prevent the transport belt from continuing to move due to inertia, and reduce the risk of cargo collision damage and slippage.

[0029] In a preferred embodiment, a screw 501 is rotatably connected to the side wall of the mounting bracket 5, and a connecting plate 502 is fixed to the side wall of the sliding bracket 6. The screws 501 are threaded together, and the limiting bracket 601 has an L-shaped structure. Rotatable sliding shafts 602 are evenly arranged inside the limiting bracket 601. Rotating the screw 501 on the side wall of the mounting bracket 5 causes the screw 501 to be threadedly connected to the connecting plate 502 fixed to the side wall of the sliding bracket 6. The rotation of the screw 501 drives the sliding bracket 6 to slide inside the mounting bracket 5, thereby moving the limiting bracket 601 and adjusting its position to prevent the transported goods from shifting to either side and reduce material falling due to the mesh belt running off-center. When the main body of the conveyor belt 203 is running, if the items run off-center, they will come into contact with the rotatable sliding shafts 602 inside the limiting bracket 601. The rotatable design of the sliding shafts 602 can reduce the friction between them and the goods.

[0030] Furthermore, any content not described in detail in this specification is existing technology known to those skilled in the art.

[0031] When the braking and limiting device for the conveyor belt is working, the motor 4 starts, and the chain wheel at its output end drives the chain wheel on the outer wall of the support shaft 201 to rotate through the chain body 401, causing the support shaft 201 to rotate, which in turn drives the roller body 202 fixed at one end to rotate synchronously, and finally drives the conveyor belt body 203 to run. During this process, the positioning teeth 302, which rotate synchronously with the support shaft 201, are tightly pressed against the positioning block 305 under the action of the spring 306. When an emergency occurs and it is necessary to stop, the motor 4 is de-energized, the support shaft 201 decelerates, and the positioning block 305 is driven into the tooth groove 303 of the positioning teeth 302 under the thrust of the spring 306. It forms a self-locking mechanism through the rotational connection with the connecting shaft 304 fixed to the inner wall of the cavity groove 301, preventing the support shaft 201 from continuing to rotate, quickly stopping the conveyor belt body 203, preventing it from continuing to move due to inertia, and reducing the risk of cargo collision damage and slippage.

[0032] Meanwhile, rotating the screw 501 on the side wall of the mounting bracket 5 causes the sliding bracket 6 to slide inside the mounting bracket 5 because the screw 501 is threadedly connected to the connecting plate 502 fixed to the side wall of the sliding bracket 6. This rotation drives the sliding bracket 6 to slide inside the mounting bracket 5, thereby moving the limiting bracket 601, which has an L-shaped structure and is uniformly provided with rotatable sliding shafts 602 inside. This adjusts the position of the limiting bracket 601, preventing the transported goods from shifting to both sides and reducing the material falling off due to the mesh belt running off-center. When the transport mesh belt body 203 is running, if the items run off-center, they will come into contact with the sliding shafts 602 inside the limiting bracket 601. The rotatable design of the sliding shafts 602 can reduce the friction between them and the goods.
