Description

Technical Field

[0001] The utility model relates to the technical field of aluminum profile feeding equipment, in particular to a feeding structure for aluminum profile rolling. Background Art

[0002] The stable, continuous and rapid development of China's national economy and high-tech has promoted the rapid development of China's aluminum smelting and aluminum profile processing industries. One of the most commonly used tools in aluminum profile processing equipment is the rolling tool. When processing aluminum profiles in factories, the scale of production is large, and the equipment needs to roll aluminum profiles of different thickness specifications. Before entering the rolling equipment, according to the specific production process, equipment configuration and product requirements, different forms of aluminum profiles (aluminum coils or aluminum sheets) are fed. They can both be used as raw materials for the rolling equipment.

[0003] The patent document with the application number 202220822181.6 discloses a feeding equipment for aluminum profile rolling, including: a controller is fixedly installed on the right side of the bottom plate; a feeding component is movably installed on the top of the bottom plate; a guiding component is fixedly installed on the front side of the bottom plate; the beneficial effects are as follows: the feeding equipment for aluminum profile rolling can be embedded in both ends of the inner circle of the aluminum coil through two mounting columns, so as to support the aluminum coil, and the aluminum coil can rotate through the first rotating shaft on the mounting column, thus facilitating the feeding of the aluminum material on the aluminum coil; and when the inner circle of the aluminum coil is larger, the second electric push rod is started, so that the second electric push rod drives the support plate to move, and the support plate is closely attached to the inner part of the inner circle of the aluminum coil.

[0004] However, during the transportation of the existing aluminum sheet, due to its own instability, external vibration and the lack of limiting equipment on the surface of the guide plate, the aluminum sheet may shift during transportation on the guide plate, and even may cause friction and jamming between multiple aluminum sheets, unable to move normally, resulting in the accumulation and blockage of aluminum sheets on the guide plate, affecting subsequent positioning and processing, and there may also be other potential safety hazards or even cause accidents. Content of the Utility Model

[0005] The utility model discloses a feeding structure for aluminum profile rolling, aiming to solve the technical problem that during the transportation of the existing aluminum sheet, due to its own instability, external vibration and the lack of limiting equipment on the surface of the guide plate, the aluminum sheet may shift during transportation on the guide plate, and even may cause friction and jamming between multiple aluminum sheets, unable to move normally, resulting in the accumulation and blockage of aluminum sheets on the guide plate, affecting subsequent positioning and processing, and there may also be other potential safety hazards or even cause accidents.

[0006] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0007] A feeding structure for aluminum profile rolling, including a workbench. Support columns are provided on the outer wall of the bottom of the workbench near the four corners. A first conveyor belt, a second conveyor belt and an inclined plate are provided on the top of the workbench. An installation opening is provided on the outer wall of the top of the inclined plate near one side outer wall. It further includes:

[0008] The first limiting mechanism: located on one outer wall of the workbench. The first limiting mechanism includes an installation frame, the installation frame is hinged to one outer wall of the workbench, upper connecting frames and lower connecting frames are respectively provided at both ends of the installation frame. A first threaded rod and a limiting rod are provided on the outer wall of the bottom of the upper connecting frame. A second limiting plate is connected to the outer wall of the first threaded rod through threads. One end of the lower connecting frame is connected to a second threaded rod through threads. One end of the second threaded rod is connected to a first limiting plate through a bearing. A knob is provided at the end of the second threaded rod far from the first limiting plate;

[0009] The second limiting mechanism: located on both sides of the first conveyor belt and the second conveyor belt.

[0010] Before use, according to the overall length of the aluminum profile plate, the user rotates the knob to drive the second threaded rod to rotate, thereby adjusting the distance between the first limiting plate and the second limiting plate. And according to the thickness of the aluminum profile plate, the user rotates the first threaded rod. At this time, the second limiting plate moves up and down on the first threaded rod under the limiting action of the limiting rod, thereby adjusting the distance between the second limiting plate and the upper surface of the inclined plate. Then, multiple aluminum profile plates to be processed are limited on both sides by the second limiting mechanism, and the first conveyor belt is used to move multiple aluminum profile plates to the inclined plate in sequence. Under normal circumstances, the position of the first limiting plate is below the position of the installation opening. When the output shaft of the first motor drives the second gear to rotate, it drives the first gear to rotate, and then drives the cam to rotate. Then, when the cam makes a circular motion and the overall center of gravity moves upward, it will push the first threaded rod upward, thereby driving the first limiting plate and the fixing frame to move upward as a whole for a certain distance. At this time, the aluminum profile plate on the first conveyor belt is intercepted by the first limiting plate, and the aluminum profile plate on the upper surface of the inclined plate moves down to the second conveyor belt. (According to actual needs, the rolling equipment can be set above the second conveyor belt). When the overall center of gravity of the convex block moves downward, the next aluminum profile plate to be processed smoothly enters the upper surface of the inclined plate. After the second limiting plate loses the upward force, it returns to its original position and intercepts the next aluminum profile plate to be processed. This device can prevent the aluminum profile plate from being blocked during the conveying process, can realize the individual feeding of aluminum profiles, improve the working efficiency of aluminum profile plate processing, and reduce the probability of safety accidents.

[0011] In a preferred embodiment, a fixing frame is provided on the outer wall of the bottom of the inclined plate. A first motor and a first gear are provided on one outer wall of the fixing frame. The output shaft of the first motor is fixedly connected to a second gear, and the second gear meshes with the first gear. A cam is provided on one outer wall of the first gear, and the speed ratio of the second gear to the first gear is 3:1.

[0012] During use, the first motor drives the second gear to rotate. Since the first gear is connected to the fixing frame by a bearing and due to the meshing action between the first gear and the second gear, the first gear rotates in place on the fixing frame, thereby driving the cam to perform a circular motion, providing power support for the up and down movement of the first limiting mechanism.

[0013] In a preferred embodiment, the second limiting mechanism includes two electric telescopic rods and two clamping plates. A push plate is provided at the movable end of the electric telescopic rod. Mounting grooves are formed on the outer walls of the opposite sides of the push plate. The two ends of the clamping plate are respectively slidably connected to the inner walls of the two mounting grooves. Seven equally spaced mounting rods and limiting springs are provided on the outer wall of the clamping plate close to the push plate. The limiting spring is wound around the circumferential outer wall of the mounting rod, and the end of the limiting spring away from the clamping plate is welded to the outer wall of the push plate. Seven equally spaced limiting grooves are formed on the outer wall of the push plate, and the mounting rod is inserted into the inner wall of the limiting groove. A number of balls are mounted on the opposite outer walls of the two clamping plates.

[0014] When the aluminum profile plate is on the first conveyor belt or the second conveyor belt, the clamping plate and the push plate maintain a certain distance through the cooperation of the limiting spring. At the same time, the two electric telescopic rods are started. Driven by the movable ends of the electric telescopic rods, the two push plates move closer to each other on both sides of the aluminum profile plate. When the clamping plate touches both sides of the aluminum profile plate, the push plate will continue to move and compress the limiting spring. The squeezing force between the ball and the aluminum profile plate plays a certain buffering role in compressing the limiting spring. The cooperation of the mounting rod and the limiting groove guides the movement of the clamping plate. At the same time, the outer wall of the mounting rod and the limiting spring cooperate to reduce the possibility of the limiting spring being bent and deformed. When the aluminum profile plate is limited, the first conveyor belt is used to drive the aluminum profile plate to move to the inclined plate or the second conveyor belt is used to drive the aluminum profile plate to move into the rolling equipment, improving the stability of the aluminum profile plate during the movement. The arranged balls can reduce the friction generated between the aluminum profile plate and the clamping plate.

[0015] As can be seen from the above, a feeding structure for aluminum profile rolling includes a workbench. Support columns are provided at the four corners of the outer wall of the bottom of the workbench. A first conveyor belt, a second conveyor belt and an inclined plate are provided on the top of the workbench. An installation opening is formed on the outer wall of the top of the inclined plate close to one outer wall. It further includes:

[0016] First limiting mechanism: Located on one outer wall of the workbench, the first limiting mechanism includes a mounting frame, the mounting frame is hinged to one outer wall of the workbench, upper connecting frames and lower connecting frames are respectively arranged at two ends of the mounting frame, a first threaded rod and a limiting rod are arranged on the bottom outer wall of the upper connecting frame, a second limiting plate is connected to the outer wall of the first threaded rod by a thread, one end of the lower connecting frame is connected to a second threaded rod by a thread, one end of the second threaded rod is connected to a first limiting plate through a bearing, and a knob is arranged at one end of the second threaded rod far away from the first limiting plate;

[0024] The following will clearly and completely describe the technical solutions in the embodiments of the present application in conjunction with the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. Usually, the components of the embodiments of the present application described and marked in the accompanying drawings here can be arranged and designed in various different configurations. Therefore, the following detailed description of the embodiments of the present application provided in the accompanying drawings is not intended to limit the scope of the present application claimed, but only represents the selected embodiments of the present application. All other embodiments obtained by those skilled in the art based on the embodiments of the present application without creative efforts belong to the scope of protection of the present application.

[0025] A feeding structure for aluminum profile rolling disclosed by the present utility model is mainly applied to the existing aluminum profile plates during the conveying process. Due to reasons such as their own instability, external vibration, and the lack of limiting devices on the surface of the guiding plate, the aluminum profile plates may shift during conveyance on the guiding plate, and even cause friction and jamming between multiple aluminum profile plates, making them unable to move normally, thus resulting in the accumulation and blockage of aluminum profile plates on the guiding plate, affecting subsequent positioning and processing, and there may also be other potential safety hazards or even accidents.

[0026] Refer to Figure 1 、 Figure 2 、 Figure 3 and Figure 5 , a feeding structure for aluminum profile rolling, includes a workbench 1. Support columns are provided on the outer wall of the bottom of the workbench 1 near the four corners. A first conveyor belt 2, a second conveyor belt 3, and an inclined plate 10 are provided on the top of the workbench 1. An installation opening is provided on the outer wall of the top of the inclined plate 10 near one side outer wall. It further includes:

[0027] The first limiting mechanism: located on one side outer wall of the workbench 1, the first limiting mechanism includes an installation frame. The installation frame is hinged to one side outer wall of the workbench 1. An upper connecting frame 4 and a lower connecting frame 15 are respectively provided at both ends of the installation frame. A first threaded rod 12 and a limiting rod are provided on the outer wall of the bottom of the upper connecting frame 4. A second limiting plate 13 is connected to the outer wall of the first threaded rod 12 through threads. One end of the lower connecting frame 15 is connected to a second threaded rod 14 through threads. One end of the second threaded rod 14 is connected to a first limiting plate 11 through a bearing. A knob is provided at the end of the second threaded rod 14 away from the first limiting plate 11.

[0028] The second limiting mechanism: located on both sides of the first conveyor belt 2 and the second conveyor belt 3.

[0029] Among them, the installation frame is a "U" - shaped structure, which is convenient for driving the first limiting plate 11 and the second limiting plate 13 to move up and down simultaneously, improving the adaptability of the first limiting mechanism.

[0030] During the specific use process, the first conveyor belt 2 and the second conveyor belt 3 are respectively located on both sides of the inclined plate 10. The second conveyor belt 3 and the bottom end of the inclined plate 10 are on the same straight line, and the top end of the inclined plate 10 and the first conveyor belt 2 are on the same straight line.

[0031] Among them, the inclined plate 10 is inclined at an angle of 30 degrees with the horizontal plane. Such a setting facilitates the use of the gravity of the aluminum profile to move downward along the surface of the inclined plate 10.

[0032] During the implementation process, a fixed frame is provided on the outer wall of the bottom of the inclined plate 10. A first motor 19 and a first gear 17 are provided on one outer wall of the fixed frame. The output shaft of the first motor 19 is fixedly connected with a second gear 18. The second gear 18 meshes with the first gear 17. A cam 16 is provided on one outer wall of the first gear 17. The speed ratio of the second gear 18 to the first gear 17 is 3:1. When in use, the first motor 19 drives the second gear 18 to rotate. Since the first gear 17 is connected to the fixed frame by a bearing method, and due to the meshing effect between the first gear 17 and the second gear 18, the first gear 17 rotates in place on the fixed frame, thereby driving the cam 16 to perform a circular motion and providing power support for the up and down movement of the first limiting mechanism.

[0033] Specifically, before use, according to the overall length of the aluminum profile, the user rotates the knob to drive the second threaded rod 14 to rotate, thereby adjusting the distance between the first limiting plate 11 and the second limiting plate 13. And according to the thickness of the aluminum profile, the user rotates the first threaded rod 12. At this time, the second limiting plate 13 moves up and down on the first threaded rod 12 through the limiting action of the limiting rod, thereby adjusting the distance between the second limiting plate 13 and the upper surface of the inclined plate 10. Then, multiple aluminum profiles to be processed are limited on both sides by the second limiting mechanism, and the first conveyor belt 2 is used to move multiple aluminum profiles to the inclined plate 10 in sequence. Under normal circumstances, the position of the first limiting plate 11 is below the position of the installation port. When the output shaft of the first motor 19 drives the second gear 18 to rotate, it drives the first gear 17 to rotate, and then drives the cam 16 to rotate. Then, when the cam 16 performs a circular motion and the overall center of gravity moves upward, it will push the first threaded rod 12 upward, thereby driving the first limiting plate 11 and the fixed frame to move upward as a whole by a certain distance. At this time, the aluminum profile on the first conveyor belt 2 is intercepted by the first limiting plate 11, and the aluminum profile on the upper surface of the inclined plate 10 moves down to the second conveyor belt 3. According to actual needs, the rolling equipment can be set above the second conveyor belt 3. When the overall center of gravity of the convex block moves downward, the next aluminum profile to be processed smoothly enters the upper surface of the inclined plate 10. After the second limiting plate 13 loses the upward force, it returns to its original position and intercepts the next aluminum profile to be processed. This device can prevent the aluminum profile from being blocked during the conveying process, can realize the individual feeding of the aluminum profile, improve the working efficiency of the aluminum profile processing, and reduce the probability of safety accidents.

[0034] Reference Figure 3

[0035] Specifically, when the first threaded rod 12 and the second limiting plate 13 cooperate to be lower than the upper surface of the inclined plate 10, the micro motor is started. The output shaft of the micro motor drives the roller 20 to rotate clockwise, thereby driving the aluminum plate to move towards the second conveyor belt 3, reducing the friction between the bottom of the aluminum plate and the upper surface of the inclined plate 10 and assisting the aluminum plate to move downward.

[0036] Reference Figure 1 and Figure 4

[0037] Specifically, when the aluminum plate is on the first conveyor belt 2 or the second conveyor belt 3, the clamping plate 6 and the push plate 5 maintain a certain distance through the cooperation of the limiting spring 8. At the same time, the two electric telescopic rods 21 are started. Driven by the movable ends of the electric telescopic rods 21, the two push plates 5 approach each other on both sides of the aluminum plate. When the clamping plate 6 touches both sides of the aluminum plate, the push plate 5 will continue to move and compress the limiting spring 8. The extrusion force between the ball 9 and the aluminum plate plays a certain buffering role in the compression of the limiting spring 8. The cooperation between the mounting rod 7 and the limiting groove plays a guiding role in the movement of the clamping plate 6. At the same time, the outer wall of the mounting rod 7 and the limiting spring 8 cooperate to reduce the possibility of the limiting spring 8 being bent and deformed. When the aluminum plate is limited, the first conveyor belt 2 is used to drive the aluminum plate to move to the inclined plate 10 or the second conveyor belt 3 is used to drive the aluminum plate to move into the rolling equipment, improving the stability of the aluminum plate during the movement. The provided ball 9 can reduce the friction generated between the aluminum plate and the clamping plate 6.

[0038] Working principle: Before use, according to the overall length of the aluminum profile plate, the user rotates the knob to drive the second threaded rod 14 to rotate, thereby adjusting the distance between the first limiting plate 11 and the second limiting plate 13. And according to the thickness of the aluminum profile plate, the user rotates the first threaded rod 12. At this time, the second limiting plate 13 moves up and down on the first threaded rod 12 under the limiting action of the limiting rod, thereby adjusting the distance between the second limiting plate 13 and the upper surface of the inclined plate 10. Then, multiple aluminum profile plates to be processed are limited on both sides by the second limiting mechanism, and the first conveyor belt 2 is used to move the multiple aluminum profile plates to the inclined plate 10 in sequence. Under normal circumstances, the position of the first limiting plate 11 is below the installation opening position. When the output shaft of the first motor 19 drives the second gear 18 to rotate, it drives the first gear 17 to rotate, and then drives the cam 16 to rotate. Then, when the cam 16 makes a circular motion and the overall center of gravity moves upward, it will push the first threaded rod 12 upward, thereby driving the first limiting plate 11 and the fixing frame to move upward as a whole by a certain distance. At this time, the aluminum profile plate on the first conveyor belt 2 is intercepted by the first limiting plate 11, and the aluminum profile plate on the upper surface of the inclined plate 10 moves down to the second conveyor belt 3. According to actual needs, the rolling equipment can be set above the second conveyor belt 3. When the overall center of gravity of the convex block moves downward, the next aluminum profile plate to be processed smoothly enters the upper surface of the inclined plate 10. After the second limiting plate 13 loses the upward force, it returns to its original position and intercepts the next aluminum profile plate to be processed.
