Description

Technical Field

[0001] The utility model relates to the technical field of brakes for permanent magnet drums, in particular to a brake for permanent magnet drums. Background Art

[0002] A permanent magnet drum is an industrial device used to transport materials or drive mechanical equipment. It consists of a rotating drum with permanent magnets inside, which generates power through magnetic fields to achieve movement. This design gives permanent magnet drums advantages over traditional electric motors in some applications, such as achieving movement without the need for an external power source.

[0003] Permanent magnetic rollers are usually used in material conveying, mixing, screening and other occasions that require continuous and stable movement. They are widely used in various industries, including logistics, food processing, mining, building materials and other fields.

[0004] In industrial production, permanent magnet rollers are often used to transport materials or drive mechanical equipment. In order to ensure workplace safety, a reliable braking system is required to stop or control the movement of the roller to prevent accidents.

[0005] A brake for a permanent magnet drum is proposed, the purpose of which is to improve the control performance of the permanent magnet drum. By precisely controlling the force applied by the brake, the movement speed of the drum can be stopped or adjusted more accurately, thereby improving production efficiency and quality. Utility Model Content

[0006] In order to solve the above technical problems, the technical solution adopted by the utility model is:

[0007] A brake for a permanent magnet drum comprises a frame, on which a permanent magnet drum is arranged, a cooling mechanism is fixedly mounted on the top of the frame, a braking mechanism is arranged at one end of the permanent magnet drum, a friction mechanism is limitedly inserted at one end of the braking mechanism, the braking mechanism comprises a base plate; the friction mechanism comprises a multi-sided limiting groove; the cooling mechanism comprises a water storage tank.

[0008] A further improvement of the technical solution of the utility model is that a hydraulic cylinder is fixedly installed on one side of the top of the base plate, a push plate is fixedly installed on the right end of the hydraulic cylinder, a base block is fixedly installed on the left side of the push plate, and the braking mechanism also includes a damping block.

[0009] A further improvement of the technical solution of the utility model is that: the damping block is fixedly installed on the right end of the permanent magnet drum.

[0010] A further improvement of the technical solution of the utility model is that the friction mechanism is limitedly inserted at the left end of the base block.

[0011] A further improvement of the technical solution of the utility model is that the polygonal limiting groove is arranged at the left end of the base block of the brake mechanism, the brake mechanism is provided with a polygonal limiting block which is inserted and limited by the polygonal limiting groove, and a friction head is fixedly installed at the left end of the polygonal limiting block.

[0012] A further improvement of the technical solution of the utility model is that: the friction head is inserted into the left end of the brake mechanism through a multi-sided limiting block.

[0013] A further improvement of the technical solution of the utility model is that: a pipeline is connected through the right end of the water storage tank, a solenoid valve is connected through the bottom of the pipeline, and a nozzle is connected through the bottom of the solenoid valve.

[0014] A further improvement of the technical solution of the utility model is that the nozzle is located above the friction mechanism and the permanent magnetic roller.

[0015] Due to the adoption of the above technical solution, the utility model has achieved the following technical progress compared with the prior art:

[0016] The utility model provides a brake for a permanent magnet drum. When the permanent magnet drum is braked, the hydraulic oil cylinder contracts to drive the push plate to move toward the base plate, thereby pushing the base block to move toward the right end of the permanent magnet drum, and the friction mechanism is limited and plugged at the left end of the base block, and finally the left end of the friction mechanism is in contact with one end of a damping block fixedly installed at the right end of the permanent magnet drum. When the hydraulic oil cylinder applies a large pressure, the friction resistance between the friction mechanism and the damping block is increased, thereby braking the permanent magnet drum. By accurately controlling the pressure of the hydraulic oil cylinder, the applied force of the brake mechanism can be accurately controlled, so that more accurate stopping or adjustment of the movement speed of the drum can be achieved, thereby improving production efficiency and quality.

[0017] The utility model provides a brake for a permanent magnet drum. Long-term friction braking or frequent braking will shorten the life of the friction head of the friction mechanism, resulting in poor braking effect. The friction head is inserted into a multilateral limiting groove at the left end of the braking mechanism through a multilateral limiting block. The multilateral plug-in structure prevents rotation between the friction head and the braking mechanism, thereby providing a stable braking force. When replacing the friction head, the friction head can be directly pulled out of the braking mechanism through the multilateral limiting block for replacement. Regular replacement of the friction head is efficient and convenient, thereby maintaining the braking effect.

[0018] The utility model provides a brake for a permanent magnet drum. During long-term friction braking or frequent braking, the temperature of the friction point between the friction mechanism and the permanent magnet drum will rise sharply. During braking, the solenoid valve opens, so that the refrigeration liquid in the water storage tank enters the nozzle through the pipeline and is finally sprayed downward through the nozzle, thereby cooling the friction point between the friction mechanism and the permanent magnet drum, preventing friction fire, and extending the service life of the friction mechanism and the brake mechanism.

DETAILED DESCRIPTION

[0025] The present invention is further described in detail below in conjunction with the embodiments:

[0026] like Figure 1-2 As shown, the utility model provides a brake for a permanent magnet drum, comprising a frame 1, on which a permanent magnet drum 5 is arranged, a cooling mechanism 4 is fixedly installed on the top of the frame 1, a brake mechanism 2 is arranged at one end of the permanent magnet drum 5, and a friction mechanism 3 is limitedly inserted at one end of the brake mechanism 2.

[0027] like Figure 3 As shown, the utility model provides a technical solution: preferably, the braking mechanism 2 includes a base plate 22, a hydraulic cylinder 23 is fixedly installed on the top side of the base plate 22, a push plate 25 is fixedly installed on the right end of the hydraulic cylinder 23, and a base block 24 is fixedly installed on the left side of the push plate 25. The braking mechanism 2 also includes a damping block 21, the damping block 21 is fixedly installed on the right end of the permanent magnet roller 5, and the friction mechanism 3 is limitedly inserted at the left end of the base block 24.

[0028] In this embodiment, when the permanent magnet drum is braked with a brake, the hydraulic cylinder 23 contracts to drive the push plate 25 to move toward the base plate 22, thereby pushing the base block 24 to move toward the right end of the permanent magnet drum 5, and the friction mechanism 3 is limitedly inserted at the left end of the base block 24, so that the left end of the friction mechanism 3 is finally in contact with one end of the damping block 21 fixedly installed at the right end of the permanent magnet drum 5. When the hydraulic cylinder 23 applies a large pressure, the friction resistance between the friction mechanism 3 and the damping block 21 increases, thereby braking the permanent magnet drum 5. By accurately controlling the pressure of the hydraulic cylinder 23, the application force of the brake mechanism 2 can be accurately controlled, so as to achieve more accurate stopping or adjustment of the movement speed of the drum, thereby improving production efficiency and quality.

[0029] like Figure 4 As shown, the utility model provides a technical solution: preferably, the friction mechanism 3 includes a multilateral limit groove 33, the multilateral limit groove 33 is opened at the left end of the base block 24 of the brake mechanism 2, the brake mechanism 2 is limitedly inserted with a multilateral limit block 32 through the multilateral limit groove 33, and the left end of the multilateral limit block 32 is fixedly installed with a friction head 31, and the friction head 31 is limitedly inserted at the left end of the brake mechanism 2 through the multilateral limit block 32.

[0030] In this embodiment, long-term friction braking or frequent braking will shorten the life of the friction head 31 of the friction mechanism 3, resulting in a deterioration in the braking effect. The friction head 31 is inserted into the multilateral limiting groove 33 at the left end of the braking mechanism 2 through a multilateral limiting block 32. The multilateral plug-in structure prevents rotation between the friction head 31 and the braking mechanism 2, thereby providing a stable braking force. When replacing the friction head 31, the friction head 31 can be directly pulled out of the braking mechanism 2 through the multilateral limiting block 32 for replacement. Regular replacement of the friction head 31 is efficient and convenient, thereby maintaining the braking effect.

[0031] like Figure 5 As shown, the utility model provides a technical solution: preferably, the cooling mechanism 4 includes a water tank 41, the right end of the water tank 41 is connected with a pipeline 42, the bottom of the pipeline 42 is connected with a solenoid valve 43, the bottom of the solenoid valve 43 is connected with a nozzle 44, and the nozzle 44 is located above the friction mechanism 3 and the permanent magnet roller 5.

[0032] In this embodiment, during long-term friction braking or frequent braking, the temperature of the friction point between the friction mechanism 3 and the permanent magnet roller 5 will rise sharply. During braking, the solenoid valve 43 opens, allowing the refrigerant liquid in the water tank 41 to enter the nozzle 44 through the pipeline 42, and finally sprayed downward through the nozzle 44, thereby cooling the friction point between the friction mechanism 3 and the permanent magnet roller 5, preventing friction fire, and extending the service life of the friction mechanism 3 and the braking mechanism 2.

[0033] The working principle of the permanent magnet drum brake is described in detail below.

[0034] like Figure 1-5 As shown, when the permanent magnet roller is braked with a brake, the hydraulic cylinder 23 contracts to drive the push plate 25 to move toward the base plate 22, thereby pushing the base block 24 to move toward the right end of the permanent magnet roller 5, and the friction mechanism 3 is limited and inserted at the left end of the base block 24, and finally the left end of the friction mechanism 3 is in contact with one end of the damping block 21 fixedly installed at the right end of the permanent magnet roller 5. When the hydraulic cylinder 23 applies a large pressure, the friction resistance between the friction mechanism 3 and the damping block 21 increases, thereby braking the permanent magnet roller 5. By accurately controlling the pressure of the hydraulic cylinder 23, the applied force of the brake mechanism 2 can be accurately controlled to achieve more accurate stopping or adjustment of the movement speed of the roller, thereby improving production efficiency and quality. Long-term friction braking or frequent braking will shorten the life of the friction head 31 of the friction mechanism 3, resulting in poor braking effect, and friction The rubbing head 31 is limited and inserted into the multilateral limiting groove 33 at the left end of the braking mechanism 2 by a multilateral limiting block 32. The multilateral plug-in structure prevents rotation between the friction head 31 and the braking mechanism 2, providing stable braking force. When replacing the friction head 31, the friction head 31 can be directly pulled out from the braking mechanism 2 through the multilateral limiting block 32 for replacement. Regular replacement of the friction head 31 is efficient and convenient, and the braking effect is maintained. During long-term friction braking or frequent braking, the temperature at the friction point between the friction mechanism 3 and the permanent magnet roller 5 will rise sharply. During braking, the solenoid valve 43 opens, allowing the refrigerant liquid in the water tank 41 to enter the nozzle 44 through the pipeline 42, and finally sprayed downward through the nozzle 44, thereby cooling the friction point between the friction mechanism 3 and the permanent magnet roller 5, preventing friction fire, and extending the service life of the friction mechanism 3 and the braking mechanism 2.

[0035] The above generally describes the present invention in detail, but it is obvious to a person skilled in the art that some modifications or improvements can be made to the present invention. Therefore, modifications or improvements that do not deviate from the spirit of the present invention are within the scope of protection of the present invention.
