[0025] To make the objectives, technical solutions, and advantages of this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of this application.

[0026] In the description of the embodiments of this application, it should be noted that, unless otherwise explicitly specified and limited, the terms "connected" and "linked" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in the embodiments of this application based on the specific circumstances.

[0027] In addition, the terms "first", "second", etc. are used only for descriptive purposes and are not to be construed as indicating or implying relative importance or an indicated number of features. Thus, features defined with "first", "second" can explicitly or implicitly include one or more of the features. In the description of the present application, the meaning of "a plurality of" is two or more, unless otherwise explicitly and specifically limited.

[0028] The application will be described below with reference to the drawings. Figures 1 to 2 The aluminum ingot conveying device of the present application is described.

[0029] Please refer to Figures 1 to 2 The aluminum ingot conveying device provided by the embodiments of the present application comprises a mounting frame 1, a conveying assembly 2, a first emergency stop assembly 3 and a second emergency stop assembly 4. The conveying assembly 2 comprises a conveying belt 21, a first driving unit 22 and a plurality of transmission rollers 23. The plurality of transmission rollers 23 are parallel to each other and are rotatably connected to the mounting frame 1. The plurality of transmission rollers 23 are drivingly connected through the conveying belt 21. The first driving unit 22 is connected to one of the transmission rollers 23 and is used to drive the transmission roller 23 to rotate. The first emergency stop assembly 3 comprises an emergency stop button 31 and a control module. The emergency stop button 31 and the first driving unit 22 are electrically connected to the control module. The second emergency stop assembly 4 comprises a brake wheel 41, a brake member 42 and a second driving unit 43. The brake wheel 41 is sleeved on one of the transmission rollers 23. The second driving unit 43 is connected to the brake member 42 and is used to drive the brake member 42 to move to contact the brake wheel 41.

[0030] Specifically, the first driving unit 22 drives the transmission roller 23 connected thereto to rotate, so that the conveying belt 21 operates to convey the aluminum ingot. Since the plurality of transmission rollers 23 are drivingly connected through the conveying belt 21, the motion states of the plurality of transmission rollers 23 are consistent. When the transmission roller 23 connected to the first driving unit 22 rotates, the other transmission rollers 23 also rotate synchronously, so that the brake wheel 41 also rotates. Since the emergency stop button 31 and the first driving unit 22 are electrically connected to the control module, when an abnormal situation occurs, the emergency stop button 31 can be pressed, so that the control module controls the first driving unit 22 to stop driving the transmission roller 23, thereby stopping the aluminum ingot conveying device. After the aluminum ingot conveying device is stopped, due to the existence of inertia, the transmission roller 23 lacking power driving will continue to rotate for a certain period of time. At this time, the second driving unit 43 can drive the brake member 42 to move to contact the brake wheel 41, and the brake member 42 and the brake wheel 41 are frictionally connected, so as to brake the brake wheel 41, thereby rapidly braking the transmission roller 23.

[0031] The aluminum ingot conveying device of the embodiment of the application can make the control module control the first driving unit 22 to stop working by pressing the emergency stop button 31, so that the transmission roller 23 loses power, and also drive the brake member 42 to move to contact the brake wheel 41 by the second driving unit 43, brake the brake wheel 41 by using the friction force, thereby braking the transmission roller 23 which loses power, avoiding the transmission roller 23 from continuing to operate due to inertia, and effectively solving the problem that the aluminum ingot conveying machine cannot quickly and urgently stop.

[0032] Please refer to Figure 2 In some embodiments, the first driving unit 22 comprises a motor 221, a belt 222 and two pulleys 223, the two pulleys 223 are respectively sleeved on the output shaft of the motor 221 and the transmission roller 23, and the two pulleys 223 are drivingly connected by the belt 222. The motor 221 drives the pulley 223 connected thereto to rotate, and then drives the other pulley 223 to rotate through the belt 222, and finally drives the transmission roller 23 to rotate. The motor 221 is electrically connected with the control module, and the start and stop of the motor 221 is controlled by the control module.

[0033] Please refer to Figure 1 In some embodiments, the mounting frame 1 comprises two frame bodies arranged at intervals, and the opposite ends of the transmission roller 23 are respectively rotatably connected with the two frame bodies; the number of the emergency stop buttons 31 is multiple, and multiple emergency stop buttons 31 are arranged at intervals on the side of the frame body away from the transmission roller 23 along the conveying direction.

[0034] Specifically, by arranging multiple emergency stop buttons 31 on the two frame bodies, and arranging the multiple emergency stop buttons 31 on the frame body at intervals along the conveying direction, when an abnormal situation occurs, the worker can choose to press the emergency stop button 31 nearby, so that the aluminum ingot conveying device can completely stop operating at the fastest speed, thereby reducing the probability of safety accidents. When the emergency stop button 31 is not pressed, the emergency stop button 31 is arranged flush or concave relative to the surface of the frame body, so as to avoid the worker from accidentally touching the emergency stop button 31.

[0035] The multiple emergency stop buttons 31 are electrically connected with the control module, and the emergency stop button 31 is configured such that as long as any one or more of the multiple emergency stop buttons 31 is pressed, the control module controls the motor 221 to stop running; when all the emergency stop buttons 31 are reset, the motor 221 is restarted, and the aluminum ingot conveying device can be restarted. The existence of the multiple emergency stop buttons 31 makes the other emergency stop buttons 31 continue to function when part of the emergency stop buttons 31 are damaged.

[0036] Please refer to Figure 1 In some embodiments, the aluminum ingot conveying device further comprises a warning device 5, and the warning device 5 is electrically connected with the control module.

[0037] Specifically, the warning device 5 can be arranged on the mounting frame 1, and the warning device 5 can be at least one of a warning light, a sound alarm and the like. For example, the warning light is green in the normal state, and turns red when the emergency stop button 31 is pressed; the sound alarm does not emit sound in the normal state, and emits an alarm sound when the emergency stop button 31 is pressed. The embodiment sets the warning device 5, thereby warning the workers when the aluminum ingot conveying device is in the emergency stop state, reminding the workers to check the safety hazards and reset the emergency stop button 31.

[0038] Referring to Figure 2 In some embodiments, the side of the brake member 42 facing the brake wheel 41 is a circular arc surface, which is matched with the outer circumferential surface of the brake wheel 41, and is used to abut against the outer circumferential surface of the brake wheel 41.

[0039] Specifically, the side of the brake member 42 facing the brake wheel 41 is a circular arc surface, which is matched with the outer circumferential surface of the brake wheel 41, and is used to abut against the outer circumferential surface of the brake wheel 41.

[0040] In other embodiments, the side of the brake member 42 facing the brake wheel 41 is provided with a circular arc-shaped groove, the bottom surface of the circular arc-shaped groove is used to abut against the outer circumferential surface of the brake wheel 41, and when the bottom surface of the circular arc-shaped groove abuts against the outer circumferential surface of the brake wheel 41, the opposite sides of the brake wheel 41 along the axial direction abut against the inner side walls of the opposite sides of the circular arc-shaped groove one by one.

[0041] Specifically, the side of the brake member 42 facing the brake wheel 41 is a circular arc surface, which is matched with the outer circumferential surface of the brake wheel 41, and is used to abut against the outer circumferential surface of the brake wheel 41.

[0042] In addition, the inner side walls of the opposite sides of the circular arc-shaped groove can also limit the brake wheel 41, thereby preventing the brake wheel 41 from swinging.

[0043] In some embodiments, the inner wall of the circular-arc-shaped groove is provided with a rough protective pad.

[0044] Specifically, the rough protective pad can be a silica gel pad or a rubber pad with certain elasticity and rough surface. When the braking member 42 abuts against the braking wheel 41, the rough protective pad is located between the braking wheel 41 and the inner wall of the circular-arc-shaped groove. The rough protective pad can be slightly deformed under the extrusion, so as to avoid the hard contact between the braking member 42 and the braking wheel 41. In addition, when the braking wheel 41 is braked, the braking wheel 41 does not directly rub against the braking member 42, but rubs against the rough protective pad, which can reduce the wear of the braking wheel 41 and the braking member 42, and also reduce the noise generated by friction. The inner wall of the circular-arc-shaped groove includes an inner bottom surface and an inner side wall.

[0045] In some embodiments, the width between the opposite two sides of the circular-arc-shaped groove gradually decreases in the direction from the slot opening to the slot bottom of the circular-arc-shaped groove; and the thickness of the braking wheel 41 along the axis direction gradually decreases in the direction from the middle part to the outer peripheral surface of the braking wheel 41.

[0046] Specifically, by setting the width of the slot opening of the circular-arc-shaped groove to be greater than the width of the slot bottom, and setting the thickness of the edge of the braking wheel 41 to be less than the thickness of the middle part, the edge of the braking wheel 41 can more easily enter the inside of the circular-arc-shaped groove when the braking member 42 approaches the braking wheel 41, which reduces the positioning accuracy requirement. The cross section of the circular-arc-shaped groove is in a horn shape structure. When the pressure between the bottom surface of the circular-arc-shaped groove and the outer peripheral surface of the braking wheel 41 increases, the pressure between the inner side wall of the circular-arc-shaped groove and the side surface of the braking wheel 41 also increases, so as to increase the friction force between the braking member 42 and the braking wheel 41, and the braking effect on the braking wheel 41 is better.

[0047] In some embodiments, the second driving unit 43 is electrically connected with the control module. When the emergency stop button 31 is pressed, the control module first controls the first driving unit 22 to stop running, and then controls the second driving unit 43 to drive the braking member 42 to brake the braking wheel 41.

[0048] Please refer to Figures 1 to 2 In some embodiments, the mounting rack 1 has a cavity inside, and the second emergency stop assembly 4 is arranged in the cavity. The second driving unit 43 includes a pneumatic cylinder 431, a connecting rod 432 and a limiting plate 433. The pneumatic cylinder 431 and the limiting plate 433 are both connected with the inner wall of the cavity. One end of the connecting rod 432 is coaxially connected with the piston rod of the pneumatic cylinder 431, and the other end penetrates through the limiting plate 433 and is connected with the side of the braking member 42 away from the braking wheel 41.

[0049] Specifically, the two frame bodies of the mounting frame 1 are internally provided with cavities, the number of the brake wheels 41 and the second emergency stop assemblies 4 is two, the two brake wheels 41 are respectively sleeved on opposite ends of the corresponding transmission rollers 23, and each cavity is internally provided with one brake wheel 41 and one second emergency stop assembly 4, and the second emergency stop assembly 4 is used for braking the brake wheel 41 in the same cavity.

[0050] In the embodiment, the brake wheel 41 and the second emergency stop assembly 4 are arranged in the cavities to be hidden. The cylinder 431 is electrically connected with the control module, the control module controls the extension and retraction of the cylinder 431, and then drives the brake piece 42 to move close to or away from the brake wheel 41 through the connecting rod 432. The limiting plate 433 is provided with a first limiting hole for the connecting rod 432 to pass through, and the first limiting hole can limit the connecting rod 432, so as to ensure that the connecting rod 432 moves along the axis direction of the piston rod of the cylinder 431.

[0051] Please refer to Figures 1 to 2 In some embodiments, the driving unit further comprises a first push plate 434, a second push plate 435, a guide rod 436, a spring 437 and a limiting block 438, the first push plate 434 is connected with one end of the connecting rod 432 away from the brake piece 42, the second push plate 435 is located on one side of the first push plate 434 away from the brake piece 42, the second push plate 435 is connected with the piston rod of the cylinder 431, the axis direction of the guide rod 436 is parallel to the axis direction of the cylinder 431, the first end of the guide rod 436 is connected with the first push plate 434, the second end of the guide rod 436 penetrates through the second push plate 435, the spring 437 is sleeved on the guide rod 436, and the spring 437 is located on the first push plate 434 and the second push plate 435, and the limiting block 438 is connected with the second end of the guide rod 436.

[0052] Specifically, the piston rod of the cylinder 431 is driven to extend and retract, so as to drive the second push plate 435 to move close to or away from the first push plate 434, when the second push plate 435 moves close to the first push plate 434, the spring 437 is compressed, the rebound force of the spring 437 drives the first push plate 434 to move away from the second push plate 435, so that the first push plate 434 drives the connecting rod 432 and the brake piece 42 to move close to the brake wheel 41. The spring 437 can prevent the pressure between the brake piece 42 and the brake wheel 41 from being too large. The second push plate 435 is provided with a second limiting hole for the guide piece to pass through, and the second limiting hole is used for limiting the guide piece; the limiting block 438 cannot pass through the second limiting hole, so as to prevent the guide rod 436 from being separated from the second push plate 435.
