Description

Technical Field

[0001] This utility model relates to the field of material feeding technology, specifically to a lifting-type material feeder for shaft production lines. Background Technology

[0002] Shaft production lines are automated or semi-automated production systems specifically designed for producing various shaft parts. At the beginning of a shaft production line, workers usually need to manually move and place the shafts to be processed onto the production line. However, due to production needs, some production lines have high processing tables, making it difficult for workers to place the shafts on them. This is especially true for some heavy shafts, where the workers' handling is strenuous and the loading efficiency is low. Utility Model Content

[0003] The purpose of this utility model is to address the shortcomings of the existing technology by providing a special lifting feeder for shaft production lines, thereby solving the problems mentioned in the background art.

[0004] To achieve this objective, the present invention adopts the following technical solution:

[0005] A lifting-type feeder for shaft production lines includes a frame with a feeding bin for placing shafts mounted on the frame. A pusher opening is located at the rear end of the feeding bin, and a pusher device is installed at the pusher opening. The pusher device includes several movable push plates and fixed push plates, which are arranged in a stepped, alternating pattern. A drive device is also installed within the frame, and is connected to the movable push plates to drive their reciprocating up-and-down motion. When a movable push plate moves upward, the shafts in the feeding bin follow it to the adjacent fixed push plate at the rear end. When the movable push plate returns to its original position downward, the shafts on the fixed push plates move to the adjacent movable push plate at the rear end.

[0006] As a preferred embodiment of a lifting feeder for shaft production lines, the pushing device further includes a mounting base, on which the fixed push plates are fixedly mounted. A pushing frame is provided inside the mounting base, and the driving device is connected to the pushing frame. The movable push plate is fixedly mounted on the pushing frame, and the movable push plate is located on the side of the fixed push plate near the discharge bin. The gap between the fixed push plate and the movable push plate is smaller than the diameter of the shaft.

[0007] As a preferred embodiment of a lifting feeder for shaft production lines, the pusher frame is provided with several first and second steps on the side near the discharge bin. The first and second steps are alternately distributed. The movable pusher plate is installed on the first step, and the fixed pusher plate is located above the second step and maintains a first distance from it. The distance difference between the top of the movable pusher plate and the top of the adjacent fixed pusher plate at the rear end is a second distance. The first distance is slightly larger than the second distance, so that the highest movable position of the movable pusher plate is slightly higher than the adjacent fixed pusher plate at the rear end.

[0008] As a preferred embodiment of a lifting feeder for shaft production lines, the foremost movable push plate is located at the push port and is on the same horizontal plane as it. In the initial state, the movable push plate is lower than the adjacent fixed push plate at the rear end, and the fixed push plate is slightly higher than the adjacent movable push plate at the rear end.

[0009] As a preferred embodiment of a lifting feeder for shaft production lines, the driving device includes a driving cylinder installed in the frame, and the output end of the driving cylinder is connected to the pusher frame.

[0010] As a preferred embodiment of a lifting feeder for shaft production lines, the drive device further includes guide rods installed on the left and right sides of the mounting base, with several guide blocks slidably connected to the guide rods, and the guide blocks being connected to the pusher frame.

[0011] As a preferred embodiment of a lifting feeder for shaft production lines, a discharge plate is provided on top of the fixed push plate at the rear end, and the discharge plate is inclined downwards.

[0012] As a preferred embodiment of a lifting feeder for shaft production lines, both the movable push plate and the fixed push plate are inclined backward.

[0013] As a preferred embodiment of a lifting feeder for shaft production lines, the discharge bin is inclined backward.

[0014] As a preferred embodiment of a lifting feeder for shaft production lines, the bottom inner wall of the discharge bin is provided with several lifting strips at intervals.

[0015] The beneficial effects of this utility model are:

[0016] The feeding machine of this utility model adopts a lifting structure design. Through the coordinated action of multiple moving push plates and fixed push plates, the shafts in the unloading bin are gradually pushed upward and then conveyed to the production line via the discharge plate. The lifting height of the feeding machine can be flexibly adjusted. The actual use needs can be met by increasing or decreasing the number of push plates or adjusting the stroke of the moving push plates, so that the feeding machine has a large height adjustment range. Workers only need to place shafts in batches in the unloading bin, which is ergonomically designed. The handling intensity is low, and the feeding efficiency is effectively improved.

Therefore, the terms used to describe positional relationships in the drawings are only for illustrative purposes and should not be construed as limiting this patent. For those skilled in the art, the specific meaning of the above terms can be understood according to the specific circumstances.

[0029] In the description of this utility model, unless otherwise explicitly specified and limited, the term "connection" or similar designation indicating the connection relationship between components should be interpreted broadly. For example, it can refer to a fixed connection, a detachable connection, or an integral part; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium; it can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0030] like Figures 1 to 3 As shown, this utility model provides a special lifting feeder for shaft production lines, including a frame 1, which can be placed at the beginning of the production line. A feeding bin 2 for placing shafts is installed on the frame 1. A push port 21 is opened at the rear end of the feeding bin 2, and a push device 4 is installed at the push port 21. The push device 4 is mainly used to push the shafts in the feeding bin 2 onto the production line.

[0031] like Figure 4As shown, the feeding device 4 specifically includes a mounting base 43, a feeding frame 44, several movable feeding plates 41, and fixed feeding plates 42. The fixed feeding plates 42 are fixedly mounted on the mounting base 43, while the movable feeding plates 41 are fixedly mounted on the feeding frame 44. Both the movable feeding plates 41 and the fixed feeding plates 42 are vertically arranged, with a stepped, alternating distribution. The movable feeding plates 41 are positioned on the side of the fixed feeding plates 42 closest to the discharge bin 2. A drive device 3 is also installed inside the frame 1, connected to the feeding frame 44. After the drive device 3 is activated, it drives the movable feeding plates 41 on the feeding frame 44 to move up and down reciprocally, while the fixed feeding plates 42 remain fixed. When the moving push plate 41 is in the rising state, since the foremost moving push plate 41 is located at the push port 21 and is on the same horizontal plane as it, the shaft in the discharge bin 2 will move upward with the first moving push plate 41. When the shaft moves to a position slightly higher than the first fixed push plate 42, the shaft will slide onto the first fixed push plate 42. After the second moving push plate 41 is reset downward, the shaft will slide onto the second moving push plate 41 again and continue to rise with the second moving push plate 41. Through the coordinated action of multiple moving push plates 41 and fixed push plates 42, the shaft in the discharge bin 2 is gradually pushed upward and finally conveyed to the production line.

[0032] like Figure 5 As shown, to precisely control the stroke of the movable pusher plate 41, the pusher frame 44 in this embodiment is provided with several first steps 441 and second steps 442 on the side near the discharge bin 2. The first steps 441 and second steps 442 are alternately distributed. The movable pusher plate 41 is installed on the first step 441, while the fixed pusher plate 42 is located above the second step 442 and maintains a first distance from it. The distance difference between the top of the movable pusher plate 41 and the top of the fixed pusher plate 42 at the rear end is the second distance. After the drive device 3 is started, the drive device 3 drives the pusher frame 44 and the movable pusher plate 41 on the pusher frame 44. The movable push plate 41 moves upward. When the second step 442 abuts against the fixed push plate 42, the pusher frame 44 will stop moving. This is the highest position that the movable push plate 41 can reach, that is, the maximum stroke of the movable push plate 41 is the first distance. In order to ensure that the shaft on the movable push plate 41 can slide onto the adjacent fixed push plate 42 at the rear end, it is necessary to ensure that the first distance is slightly greater than the second distance during installation, so that the movable push plate 41 can be slightly higher than the adjacent fixed push plate 42 at the rear end after reaching the maximum stroke, thereby guiding the shaft to slide from the movable push plate 41 onto the adjacent fixed push plate 42 at the rear end.

[0033] Meanwhile, to ensure that the shaft on the fixed push plate 42 can slide onto the adjacent movable push plate 41 at the rear end when the movable push plate 41 is reset, the initial state of the fixed push plate 42 needs to be slightly higher than the adjacent movable push plate 41 at the rear end.

[0034] To ensure that the shaft can move from the movable push plate 41 to the adjacent fixed push plate 42 at the rear end, and can move from the fixed push plate 42 to the adjacent movable push plate 41 at the rear end, the movable push plate 41 and the fixed push plate 42 in this embodiment are preferably arranged to be tilted backward, so that the shaft on the movable push plate 41 or the fixed push plate 42 has a guiding force for backward movement.

[0035] The lifting height of the feeder in this embodiment can be flexibly adjusted. The actual usage needs can be met by increasing or decreasing the number of movable push plates 41 and fixed push plates 42 or adjusting the stroke of movable push plates 41. This gives the feeder a large height adjustment range. Workers only need to batch-load shaft parts in the ergonomically designed feeding bin 2, resulting in low handling intensity and effectively improving feeding efficiency.

[0036] To ensure that the movable push plate 41 can move up and down along the fixed push plate 42 and reduce friction, a gap is left between the movable push plate 41 and the fixed push plate 42 in this embodiment. At the same time, to prevent the shaft from falling out of the gap between the fixed push plate 42 and the movable push plate 41, the gap between the fixed push plate 42 and the movable push plate 41 in this embodiment is smaller than the diameter of the shaft.

[0037] like Figure 6 As shown, the driving device 3 in this embodiment specifically includes a driving cylinder 31 installed in the frame 1. The output end of the driving cylinder 31 is connected to the pusher frame 44. After the driving cylinder 31 is started, it can drive the pusher frame 44 and the movable push plate 41 on the pusher frame 44 to move up and down reciprocally.

[0038] Preferably, to improve the stability of the pusher frame 44 when it moves, the drive device 3 also includes guide rods 32 installed on the left and right sides of the mounting base 43. Several guide blocks 33 are slidably connected to the guide rods 32. The guide blocks 33 are connected to the pusher frame 44. When the pusher frame 44 moves, the guide rods 32 can provide guidance for it.

[0039] To facilitate the transfer of the shaft on the pusher 4 to the production line, in this embodiment, a discharge plate 5 is provided on the top of the fixed pusher 42 at the last end. The discharge plate 5 is preferably inclined downward. When the shaft moves to the fixed pusher 42 at the last end, the shaft will enter the production line under the guidance of the discharge plate 5.

[0040] Preferably, in order to guide the shafts in the discharge bin 2 to the push port 21, the discharge bin 2 in this embodiment is preferably tilted backward, so that the shafts in the discharge bin 2 move sequentially toward the push port 21. At the same time, in order to reduce the friction between the shafts and the bottom of the discharge bin 2, the bottom inner wall of the discharge bin 2 in this embodiment is provided with a number of lifting strips 22 at intervals. The shafts can be placed on the lifting strips 22, thereby reducing the contact area of ​​the shafts and allowing the shafts to slide in the discharge bin 2.

[0041] It is understood that, in this embodiment, the front end is the side closer to the discharge bin 2, and the rear end is the side farther away from the discharge bin 2.

[0042] It should be stated that the above-described specific embodiments are merely preferred embodiments of this utility model and the technical principles employed. Those skilled in the art should understand that various modifications, equivalent substitutions, and variations can be made to this utility model. However, such variations, as long as they do not depart from the spirit of this utility model, should be within the protection scope of this utility model. Furthermore, some terminology used in this application specification and claims is not limiting, but merely for ease of description.
