Description

Technical Field

[0001] This utility model belongs to the field of aluminum profile processing technology, and in particular relates to a feeding device for aluminum profile production and processing. Background Technology

[0002] Metal casting is a process in which molten metal is poured into a mold of a specific shape, and after cooling and solidification, a casting with a predetermined shape, size, and properties is obtained. Casting of other materials using the same process or equipment involves producing products with specific shapes, sizes, and properties from non-metallic materials such as plastics and ceramics through similar melting, pouring, and cooling processes. After the aluminum profiles are cast into sheet metal, they require further processing.

[0003] In existing aluminum profile processing, workers typically need to place the aluminum profiles on the processing table. This method has a low degree of automation and low feeding efficiency. It not only increases labor costs, but also puts workers in close proximity to the processing tools when feeding the aluminum profiles, which can easily cause injury. Therefore, we propose a feeding device for aluminum profile production and processing. Utility Model Content

[0004] The purpose of this invention is to provide a feeding device for aluminum profile production and processing. Specifically, by setting up a feeding assembly, the top aluminum plate on the placement plate is moved above the processing table. Then, a second motor drives a second threaded rod to rotate clockwise. At this time, a moving block, through a connecting rod, drives a push plate to move to the right. The push plate then pushes the top aluminum plate to the right, placing it on the processing table for processing. After processing, the next aluminum plate is fed, pushing the processed aluminum plate to the right onto a conveyor belt, which then transports the processed aluminum plate. This method automatically completes feeding and unloading, achieving a higher degree of automation, reducing manual operation, and improving safety. It solves the problem that existing aluminum profile processing methods typically require workers to place the aluminum profiles on the processing table, resulting in low automation, low feeding efficiency, and increased labor costs.

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0006] This utility model relates to a feeding device for aluminum profile production and processing, comprising a workbench, a processing device on the top of the workbench, a feeding assembly on the left side of the workbench, the feeding assembly including a fixed frame, a placement plate on the inner side of the fixed frame, several aluminum plates arranged vertically on the top of the placement plate, an L-shaped positioning plate fixedly connected to the top of the placement plate, a crossbeam fixedly connected to the left side of the inner wall of the fixed frame, a moving block slidably connected to the top of the crossbeam, a threaded hole I inside the moving block, a threaded rod II threadedly connected to the moving block through the threaded hole I, the left side of the threaded rod II rotatably connected to the fixed frame, and the right side of the threaded rod II rotatably connected to the right side of the crossbeam, a motor II fixedly connected to the left side of the fixed frame, the right output end of the motor II fixedly connected to the left side of the threaded rod II through a coupling, a connecting rod fixedly connected to the bottom of the moving block, and a push plate fixedly connected to one end of the bottom of the connecting rod;

[0007] A processing table is fixedly connected to the center of the top of the workbench. Auxiliary tables are set on the left and right sides of the processing table. The bottom of the auxiliary tables is fixedly connected to the top of the workbench. A conveyor belt is set inside the auxiliary table on the right side. A motor is fixedly connected to the front of the auxiliary table on the right side. When the motor is started, it drives the threaded rod to rotate clockwise. At this time, the moving block drives the push plate to move to the right through the connecting rod. The push plate pushes the top aluminum plate to the right, so that it moves to the processing table. After processing, the next aluminum plate is loaded, and the processed aluminum plate is pushed to the right onto the conveyor belt. The processed aluminum plate is then transported by the conveyor belt. This method can automatically complete the loading and unloading.

Support blocks are rotatably connected to the top and bottom of the threaded rod. The right sides of the two support blocks are fixedly connected to the left side of the fixing frame. A motor is fixedly connected to the top of the upper support block. Starting the motor drives the threaded rod to rotate clockwise, causing the lifting block to move the placement plate upward, which can transport the aluminum plates on the placement plate upward one by one.

[0009] Furthermore, the inner side of the L-shaped positioning plate contacts the surface of the aluminum plate, and both limiting posts are set on the left side of the placement plate. The bottom output end of the motor is fixedly connected to the top of the threaded rod through a coupling. A groove is opened at the bottom of the crossbeam, and the connecting rod is slidably connected inside the groove at the bottom of the crossbeam. A guide plate is set on the left side of the worktable, and two support rods are fixedly connected to the bottom of the guide plate. The bottom of each support rod is fixedly connected to the top of the worktable. The connecting rod slides in the groove on the crossbeam, which can play a limiting role and make the connecting rod move in a straight line.

[0010] Furthermore, two limiting plates are fixedly connected to the top of each of the two auxiliary platforms. A fixed clamping plate is fixedly connected to the rear position of the top of the processing platform, and a movable clamping plate is in contact with the front position of the top of the processing platform. A fixed plate is fixedly connected to the front of the processing platform, and an electric push rod is fixedly connected to the front of the fixed plate. The output end of the back of the electric push rod is fixedly connected to the front of the movable clamping plate. After the aluminum plate is moved onto the processing platform, the electric push rod is activated to drive the movable clamping plate to move backward. The movable clamping plate then cooperates with the fixed clamping plate to clamp and fix the aluminum plate, which facilitates subsequent processing operations.

[0011] Furthermore, transmission rollers are connected to both the left and right sides of the inner wall of the conveyor belt, and connecting shafts are fixedly connected to the central shafts of the two transmission rollers.

A support plate is in contact with the top of the inner wall of the conveyor belt, and the front and back of the support plate are fixedly connected to the inner wall of the auxiliary platform on the right. The support plate is used to support the aluminum plate on the conveyor belt and prevent the conveyor belt from denting.

[0012] Furthermore, the L-shaped positioning plate has a scale on its inner side, a fixing block is fixedly connected to the back of the L-shaped positioning plate, a threaded shaft is rotatably connected inside the fixing block, a throttle handle is fixedly connected to the bottom of the threaded shaft, and two limiting rods are fixedly connected to the top of the L-shaped positioning plate; since the limiting rods limit the lifting plate, the lifting plate can move in a straight line.

[0013] Furthermore, a lifting plate is provided above the L-shaped positioning plate, a contact sensor is fixedly connected to the bottom of the lifting plate, a controller is fixedly connected to the top of the lifting plate, a threaded shaft passes through the lifting plate and extends to the outside, the threaded shaft is threadedly connected to the lifting plate, the lifting plate is slidably limited by two limit rods, a pointer plate is fixedly connected to the right side of the contact sensor; the output signal terminal of the contact sensor is connected to the input port of the controller, and the output port of the controller is connected to a motor.

[0014] This utility model has the following beneficial effects:

[0015] 1. This utility model, through the setting of a feeding component, specifically moves the top aluminum plate on the placement plate to the processing table. Then, the starting motor drives the threaded rod to rotate clockwise. At this time, the moving block drives the push plate to move to the right through the connecting rod. The push plate then pushes the top aluminum plate to the right, moving it onto the processing table for processing. After processing, the next aluminum plate is fed, pushing the processed aluminum plate to the right onto the conveyor belt, which then transports the processed aluminum plate. This method can automatically complete the feeding and unloading, with a higher degree of automation, reducing manual operation, and improving safety.

[0016] 2. This utility model features a placement plate, specifically a placement plate on which multiple aluminum plates can be placed. After one aluminum plate is loaded, the motor is restarted to drive the threaded rod to rotate clockwise, causing the lifting block to move the placement plate upwards, thus moving the top aluminum plate to a position above the processing table. This facilitates the loading of aluminum plates one by one, achieving the function of material storage, and this loading method can improve loading efficiency.

[0017] 3. This utility model features a lifting plate. Specifically, rotating the handle drives the threaded shaft to rotate, causing the lifting plate to move up or down, thereby raising or lowering the contact sensor. By observing the position of the pointer plate on the scale, the position of the contact sensor can be determined. By adjusting the position of the contact sensor, aluminum plates of different thicknesses can be accurately raised to a position flush with the auxiliary table, facilitating subsequent loading.

[0018] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

[0039] One specific application of this embodiment is:

[0040] After aluminum profiles are cast, they cool and solidify to obtain castings with predetermined shapes, sizes, and properties. When these formed aluminum profiles need to be processed, the cast aluminum plates 123 are placed sequentially on the placement plate 122 by a robotic arm, and the cast aluminum plates 123 are brought into contact with the inner side of the L-shaped positioning plate 124, thereby positioning the cast aluminum plates 123. After multiple aluminum plates 123 are placed, the motor 224 is started to drive the threaded rod 222 to rotate clockwise, causing the lifting block 221 to move the placement plate 122. 22 moves upward, at which point the placement plate 122 slides on the limiting post 225. By raising the placement plate 122, the uppermost aluminum plate 123 comes into contact with the contact sensor 261. When the contact sensor 261 detects a contact signal, it sends it to the controller 262. Subsequently, the controller 262 controls the motor 224 to stop, allowing the aluminum plate 123 to rise accurately to the required position. Then, the push plate 253 pushes the uppermost aluminum plate 123 onto the auxiliary platform 14. The output signal terminal of the contact sensor 261 is connected to the control... The input port and output port of controller 262 are connected to motor 224. Before feeding, push plate 253 is positioned to the left of aluminum plate 123 on placement plate 122. When feeding is required, motor 255 is started to drive threaded rod 254 to rotate clockwise. At this time, moving block 251 drives push plate 253 to move to the right through connecting rod 252. Push plate 253 then pushes the uppermost aluminum plate 123 to the right, moving aluminum plate 123 to the auxiliary platform 14 on the left. Limiting plate 141 then positions aluminum plate 123. The aluminum plate 123 is moved onto the processing table 13 by the continuous pushing of the push plate 253. At this time, the push plate 253 stops moving and the motor 255 is started to drive the threaded rod 254 to rotate in the opposite direction, so that the push plate 253 moves to the left and resets. When the push plate 253 pushes the aluminum plate 123 onto the auxiliary table 14, the guide plate 2 is installed on the left side of the worktable 1 and is inclined, so it can guide the aluminum plate 123 and move the aluminum plate 123 smoothly to the top of the auxiliary table 14, avoiding jamming with the auxiliary table 14.

[0041] After the cast aluminum plate 123 is moved onto the processing table 13, the electric push rod 134 is activated to move the moving clamping plate 132 backward. The moving clamping plate 132 cooperates with the fixed clamping plate 131 to clamp and fix the aluminum plate 123. Then the processing equipment 11 can process the aluminum plate 123. During the processing, the motor 224 is activated again to drive the threaded rod 222 to rotate clockwise, so that the uppermost aluminum plate 123 moves upward again to contact the contact sensor 261. Then the upward movement of the aluminum plate 123 stops, and the aluminum plate 123 is lifted to the right by the push plate 253, so that the aluminum plate 123 moves to the left auxiliary table 14 to wait. The aluminum plate 123 on the processing table 13 is then ready to move. 3. After processing is completed, the electric push rod 134 drives the moving clamp 132 to reset forward, releasing the fixation of the aluminum plate 123. Then, the push plate 253 pushes the unprocessed aluminum plate 123 to the right, moving it to the processing table 13. The processed aluminum plate 123 is then pushed to the right, moving it to the conveyor belt 15 of the right auxiliary table 14. The conveyor belt 15 supports the aluminum plate 123 through the support plate 153. Then, the motor 142 is started to drive the connecting shaft 152 on the left to rotate clockwise. The transmission roller 151 on the left drives the conveyor belt 15 to the right, thus conveying the processed aluminum plate 123. At this time, the aluminum plate 123 on the processing table 13 is clamped and fixed for processing.

[0042] When feeding aluminum plates 123 of different thicknesses, the operator adjusts the position of the contact sensor 261 in advance. By rotating the handle 244, the threaded shaft 243 is rotated, and the lifting plate 126 will move up or down. Since the limit rod 245 limits the lifting plate 126, the lifting plate 126 can move in a straight line, thereby driving the contact sensor 261 to rise and fall. By observing the position of the pointer plate 263 on the scale 241, the position of the contact sensor 261 can be determined. By adjusting the position of the contact sensor 261, the aluminum plate 123 can be accurately raised to the same level as the auxiliary table 14 when feeding aluminum plates 123 of different thicknesses, which facilitates subsequent feeding.
