A plate feeding device

Abstract

This utility model relates to a sheet material feeding device, belonging to the field of sheet material feeding technology. The sheet material feeding device includes a worktable and a sheet material body disposed on top of the worktable. A storage rack for storing the sheet material body is fixedly connected to the top of the worktable. An intermittent continuous feeding mechanism for continuously feeding the sheet material body is provided inside the worktable. This sheet material feeding device uses a drive motor to rotate a transmission wheel, which in turn drives a driven wheel to rotate via a transmission belt. This allows the connecting seat to move on the transmission belt. A movable cover and a return spring are also included. When the movable cover moves to the bottom of the sheet material body, the sheet material body compresses the movable cover, thus compressing the return spring.

The feeding is not affected by the thickness of the sheet material body, and the feeding is highly smooth.

Description

Technical Field

[0001] This utility model relates to the field of sheet material feeding technology, specifically a sheet material feeding device. Background Technology

[0002] Sheet metal feeding is a crucial step in industrial production (such as sheet metal processing, furniture manufacturing, and automotive parts production) to transport sheet metal (metal sheets, wood sheets, plastic sheets, etc.) from storage locations to processing equipment (such as cutting machines, stamping machines, welding machines, etc.). Its efficiency and stability directly affect the overall capacity and processing precision of the production line. The core of sheet metal feeding is to achieve efficient, accurate, and stable transfer of sheet metal to the processing station, while avoiding damage to the sheet metal (such as scratches and deformation), and adapting to sheet metal of different specifications (size, thickness, material).

[0003] Chinese utility model patent CN220885850U discloses a sheet metal feeding device. The feeding platform is connected to a sheet metal lifting assembly and a pusher plate lifting assembly, and the pusher plate lifting assembly is connected to a pusher plate assembly. The pusher plate lifting assembly includes a pusher plate lifting electric push rod, which is connected to the middle of one end of the feeding platform. The push rod of the pusher plate lifting electric push rod is connected to a guide plate. The pusher plate assembly includes a pusher plate electric push rod, and the middle of one side of the guide plate is connected to the pusher plate electric push rod. This utility model relates to the field of sheet metal feeding technology, and particularly to a sheet metal feeding device. This utility model addresses the shortcomings of existing technologies by developing a sheet metal feeding device that enables the sheet metal to move along its height direction with equal sheet metal thickness, allowing the pusher plate to push the sheet metal one by one to the processing position, thus achieving feeding.

[0004] However, this utility model occupies a large space during use and requires synchronous operation of the electric push rod and motor. Since the consistency of operation between the electric push rod and motor is difficult to guarantee, it can easily affect the smoothness of the entire feeding process of the sheet metal feeding device. Furthermore, when feeding sheets of different thicknesses, the sheet metal feeding device needs to be readjusted, failing to meet the requirements for convenient feeding. Therefore, a sheet metal feeding device is proposed to solve the problems mentioned above. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a sheet metal feeding device that is not only smaller in size but also improves the smoothness of sheet metal feeding. It solves the problems of existing sheet metal feeding devices occupying a large space and requiring synchronized operation of an electric push rod and motor. Furthermore, the consistency of operation between the electric push rod and motor is difficult to guarantee, which can easily affect the smoothness of the entire feeding process. In addition, when feeding sheets of different thicknesses, the sheet metal feeding device needs to be readjusted, failing to meet the requirements for convenient feeding.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a sheet material feeding device, comprising a workbench and a sheet material body disposed on the top of the workbench, the sheet material feeding device further comprising a storage rack fixedly disposed on the top of the workbench and an intermittent continuous feeding mechanism disposed inside the workbench, the storage rack being able to centrally store the sheet material body, and the intermittent continuous feeding mechanism being able to continuously feed the sheet material body stored on the storage rack;

[0007] The intermittent continuous feeding mechanism includes a transmission wheel, a driven wheel, a transmission belt, a drive motor, and an elastic feeding structure. The transmission wheel is rotatably connected inside the worktable, and the driven wheel is rotatably connected inside the worktable on the side away from the transmission wheel. A transmission belt drives the transmission wheel and the driven wheel. A drive motor that can drive the transmission wheel is fixedly connected inside the worktable. An elastic feeding structure that can fit against the main body of the sheet is provided outside the transmission belt.

[0008] Furthermore, the elastic feeding structure includes a connecting seat fixedly connected to the outside of the transmission belt, a mounting shell fixedly connected to the bottom of the connecting seat, a movable cover extending to the bottom of the mounting shell slidably connected to the outside of the mounting shell, and a return spring fixedly connected between the movable cover and the mounting shell.

[0009] Furthermore, an anti-slip plate is fixedly connected to the side of the movable cover away from the connecting seat, and a movable groove adapted to the movable cover is provided on the upper surface of the workbench.

[0010] Furthermore, a positioning block extending into the interior of the mounting housing is fixedly connected to the inner wall of the movable cover, and a positioning groove adapted to the positioning block is provided on the outer wall of the mounting housing.

[0011] Furthermore, the plate feeding device also includes a roller conveying mechanism for conveying the plate body. The roller conveying mechanism is located on the worktable near the intermittent continuous feeding mechanism and is connected to the intermittent continuous feeding mechanism.

[0012] Furthermore, the roller conveying mechanism includes a mounting frame, a threaded rod, a movable frame, a first feeding cylinder, a rotating handle, and a second feeding cylinder. The mounting frame is fixedly connected to one side of the top of the worktable. The top of the mounting frame is threadedly connected to a threaded rod extending into it. The bottom end of the threaded rod is rotatably connected to the movable frame. The first feeding cylinder is rotatably connected inside the movable frame. The top end of the threaded rod is fixedly connected to a rotating handle. The second feeding cylinder is rotatably connected to the side of the worktable near the mounting frame.

[0013] Furthermore, the front and back of the movable frame are fixedly connected with limiting blocks extending into the interior of the mounting frame, and the inner wall of the mounting frame is provided with limiting grooves that are adapted to the limiting blocks.

[0014] Furthermore, the upper surface of the second feeding cylinder is tangent to the upper surface of the worktable, and a motor capable of driving the second feeding cylinder is fixedly connected inside the worktable.

[0015] Compared with the prior art, the present invention provides a plate feeding device, which has the following beneficial effects:

[0016] 1. This sheet material feeding device uses a drive motor to rotate a transmission wheel, which in turn drives a driven wheel via a transmission belt. This allows the connecting seat to move along the transmission belt. A movable cover and a return spring are also included. When the movable cover reaches the bottom of the sheet material, the sheet material compresses the movable cover, thus compressing the return spring. Simultaneously, an anti-slip plate allows the movable cover to move the sheet material to the right, effectively feeding the sheet material without being affected by its thickness, and with good smoothness.

[0017] 2. This sheet metal feeding device, by rotating a handle to drive a threaded rod, moves the movable frame and the first feeding cylinder downwards. A second feeding cylinder facilitates continued conveying of the sheet metal body, significantly improving feeding efficiency. This solves the problems of existing feeding devices, which occupy a large space and require synchronized operation of an electric push rod and motor. Furthermore, the inconsistent operation of the electric push rod and motor can affect the smoothness of the entire feeding process. Additionally, when feeding sheets of different thicknesses, the feeding device needs to be readjusted, failing to meet the requirements for convenient feeding. Attached Figure Description

[0023] 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.

[0024] Please see Figures 1 to 3 This embodiment of a sheet material feeding device includes a workbench 1 and a sheet material body 2 disposed on the top of the workbench 1. The sheet material feeding device also includes a storage rack 3 fixedly disposed on the top of the workbench 1 and an intermittent continuous feeding mechanism disposed inside the workbench 1. The storage rack 3 can centrally store the sheet material body 2, and the intermittent continuous feeding mechanism can continuously feed the sheet material body 2 stored on the storage rack 3. The intermittent continuous feeding mechanism includes a transmission wheel 4, a driven wheel 5, a transmission belt 6, a drive motor 7, and an elastic feeding structure. The transmission wheel 4 is rotatably connected to the inside of the workbench 1, and the driven wheel 5 is rotatably connected to the side of the inside of the workbench 1 away from the transmission wheel 4. The transmission belt 6 is connected between the transmission wheel 4 and the driven wheel 5. The drive motor 7, which can drive the transmission wheel 4, is fixedly connected inside the workbench 1. An elastic feeding structure that can fit against the sheet material body 2 is disposed outside the transmission belt 6.

[0025] Specifically, the elastic feeding structure includes a connecting seat 8 fixedly connected to the outside of the transmission belt 6, a mounting shell 9 fixedly connected to the bottom of the connecting seat 8, a movable cover 10 extending to the bottom of the mounting shell 9 slidably connected to the outside of the mounting shell 9, and a return spring 12 fixedly connected between the movable cover 10 and the mounting shell 9.

[0026] It should be noted that an anti-slip plate 11 is fixedly connected to the side of the movable cover 10 away from the connecting seat 8, an movable groove adapted to the movable cover 10 is opened on the upper surface of the workbench 1, a positioning block extending into the interior of the mounting housing 9 is fixedly connected to the inner wall of the movable cover 10, a positioning groove adapted to the positioning block is opened on the outer wall of the mounting housing 9, and a controller is fixedly connected to the front of the workbench 1.

[0027] It should be noted that by setting the drive motor 7 to drive the transmission wheel 4 to rotate, the transmission wheel 4 can drive the driven wheel 5 to rotate simultaneously through the transmission belt 6, so that the connecting seat 8 can move on the transmission belt 6. By setting the movable cover 10 and the return spring 12, when the movable cover 10 moves to the bottom of the plate body 2, the plate body 2 will squeeze the movable cover 10, thereby compressing the return spring 12. At the same time, through the anti-slip plate 11, the movable cover 10 can drive the plate body 2 to move to the right, thereby achieving the effect of feeding the plate body 2. Meanwhile, the drive motor 7 can run continuously, achieving the effect of intermittent continuous feeding, eliminating the need for a synchronous control system and greatly saving control costs.

[0028] Please see Figure 1 and Figure 4 In this embodiment, the plate feeding device further includes a roller conveying mechanism for conveying the plate body 2. The roller conveying mechanism is located on the workbench 1 near the intermittent continuous feeding mechanism. The roller conveying mechanism is connected to the intermittent continuous feeding mechanism. The roller conveying mechanism includes a mounting frame 13, a threaded rod 14, a movable frame 15, a first feeding cylinder 16, a rotating handle 17, and a second feeding cylinder 18. The mounting frame 13 is fixedly connected to one side of the top of the workbench 1. The top of the mounting frame 13 is threadedly connected to the threaded rod 14 extending into it. The bottom end of the threaded rod 14 is rotatably connected to the movable frame 15. The first feeding cylinder 16 is rotatably connected inside the movable frame 15. The top end of the threaded rod 14 is fixedly connected to the rotating handle 17. The second feeding cylinder 18 is rotatably connected to the side of the workbench 1 near the mounting frame 13.

[0029] Specifically, the front and back of the movable frame 15 are fixedly connected with limiting blocks extending into the interior of the mounting frame 13, and the inner wall of the mounting frame 13 is provided with limiting grooves that are adapted to the limiting blocks.

[0030] It should be noted that the upper surface of the second feeding cylinder 18 is tangent to the upper surface of the worktable 1, and a motor capable of driving the second feeding cylinder 18 is fixedly connected inside the worktable 1.

[0031] It should be noted that by rotating the rotating handle 17 to drive the threaded rod 14 to rotate, the movable frame 15 and the first feeding cylinder 16 can be moved downward. Furthermore, by setting the second feeding cylinder 18, it is convenient to continue conveying the main body of the plate 2, which greatly improves the feeding efficiency.

[0032] The working principle of the above embodiments is as follows:

[0033] First, the staff places the main body 2 of the sheet material inside the storage rack 3. Then, they rotate the rotating handle 17 to move the movable rack 15 downwards, so that the distance between the first feeding cylinder 16 and the second feeding cylinder 18 is the same as the thickness of the main body 2 of the sheet material. Then, they start the drive motor 7 to drive the transmission wheel 4 to rotate. When the connecting seat 8 moves to the bottom of the main body 2 of the sheet material, it drives the main body 2 of the sheet material to move to the right. At this time, the main body 2 of the sheet material is placed between the first feeding cylinder 16 and the second feeding cylinder 18. At the same time, when the motor drives the second feeding cylinder 18 to rotate, the main body 2 of the sheet material is fed.

[0034] The installation, connection, or setting methods disclosed in this embodiment are all common mechanical connection methods, and any method that achieves the desired beneficial effect can be implemented. Furthermore, all electrical components in this embodiment are electrically connected to the main controller and power supply. The main controller can be a conventional, known device such as a computer that performs control functions. Those skilled in the art can control the electrical components through simple programming, and the existing disclosed power connection technologies are common knowledge in the field. Therefore, this embodiment will not elaborate further on their specific structural composition and working principles.
