Technical Field

[0001] This utility model relates to the field of leather production technology, and in particular to a leather sorting table. Background Technology

[0002] Leather is animal hide that has been processed through hair removal, tanning, and other techniques. It retains the natural grain and luster on the surface and is composed of tightly woven natural protein fibers, giving it resistance to decay and flexibility.

[0003] Currently, leather production requires personnel to sort leather and remove damaged or defective leather. Most leather sorting is done manually. Traditional sorting requires multiple people to lift the entire piece of leather to the inspection table and then inspect it from multiple angles. During the handling and movement of the leather, the heavy weight of the leather and the back-and-forth handling can easily cause muscle strain for workers, resulting in low sorting efficiency. Utility Model Content

Detailed Implementation

[0020] The technical solution of this utility model will be further described below with reference to the accompanying drawings and embodiments.

[0021] Example:

[0022] Reference Figures 1-3 This device is a leather sorting table, including a fixed plate 1, a fixed frame 2 and a detection table 3 fixed on the fixed plate 1, a plurality of transport rollers 4 for transporting leather on the fixed frame 2, and a transfer assembly for moving the leather to the detection table 3 on the fixed frame 2 and in the transport direction of the plurality of transport rollers 4. The transfer assembly includes a cylinder 6, a drive block 7, a rotating plate 8 with a plurality of balls on its top, and a flipping component. The cylinder 6 is fixed on the fixed frame 2, and the extension and retraction direction of the cylinder 6 is parallel to the transport direction of the plurality of transport rollers 4. The drive block 7 is L-shaped and slides horizontally on the fixed plate 1. Figure 1 and Figure 2 As shown, a horizontal groove 9 is provided on the fixed plate 1, and a slider 10 is fixed on the side wall of the drive block 7. The slider 10 slides into the groove 9 to realize the sliding of the drive block 7 on the fixed plate 1. The rotating plate 8 is located above the drive block 7 and is horizontally slidably disposed on the fixed plate 1. A horizontal sliding hole 11 is provided on the fixed plate 1, and a sliding rod 12 is fixed on the side wall of the rotating plate 8. The end of the sliding rod 12 slides through the sliding hole 11 to realize the sliding of the rotating plate 8 on the fixed plate 1.

[0023] like Figure 1 and Figure 2 As shown, one end of the drive block 7 is fixed to the telescopic end of the cylinder 6, and the other end of the drive block 7 is vertically upward and hinged to the bottom of the rotating plate 8. A drive groove 15 is provided at the bottom of the rotating plate 8, and a drive rod 16 is rotatably mounted in the drive groove 15. The top of the drive block 7 is fixed to the drive rod 16, and the drive rod 16 is coaxial with the slide rod 12. The flipping component is provided on the fixed plate 1 and includes a gear 13 and a rack 14. The gear 13 is fixedly sleeved on the end of the slide rod 12 away from the rotating plate 8, and the rack 14 is horizontally fixed on the fixed plate 1. The gear 13 and the rack 14 mesh with each other. With this arrangement, the drive rod 16 can be driven by the telescopic movement of the cylinder 6 to slide the rotating plate 8, and the rotating plate 8 can be flipped by the meshing of the gear 13 and the rack 14. The top surface of the rotating plate 8 is lower than or equal to the top surface of several conveying rollers 4 in the horizontal state. A support block 17 is fixed on the fixed plate 1 to support the rotating plate 8 when it is in the horizontal state.

[0024] like Figure 1 and Figure 3 As shown, the inspection platform 3 is equipped with an inspection plate 5 for receiving leather that slides off the rotating plate 8 after it is flipped over. A motor 18 is fixed to the bottom of the inspection platform 3, and a rotating rod 19 is fixed to the axis of the inspection plate 5. Both the output end of the motor 18 and the rotating rod 19 are equipped with meshing bevel gears 20. This configuration allows the motor 18 to drive its output end to rotate, and the two bevel gears 20 to slowly rotate the rotating rod 19 and the inspection plate 5, further rotating the leather that falls onto the inspection plate 5. A light 21 is mounted on the fixed plate 1 above the inspection platform 3.

[0025] Working principle:

[0026] In use, the leather is first transported by several transport rollers 4 on the fixed frame 2. When the leather is transported to the transfer assembly area, the cylinder 6 is activated, and its telescopic end pushes the drive block 7 to slide horizontally along the slide groove 9 on the fixed plate 1. One end of the drive block 7 is fixedly connected to the telescopic end of the cylinder 6, and the other end is fixedly connected upward to the drive rod 16 rotating at the bottom of the rotating plate 8. The movement of the drive block 7 drives the rotating plate 8 to slide horizontally on the fixed plate 1 through the drive rod 16 fixed to its top. In the initial sliding stage, since the rotating plate 8 is in a horizontal position and its top surface is lower than or equal to the top surface of the transport rollers 4, the leather can smoothly transition from the transport rollers 4 to the balls of the rotating plate 8. As the rotating plate 8 continues to move horizontally, the gear 13 fixed to the end of the slide rod 12 rolls and meshes along the rack 14 fixed on the fixed plate 1, forcing the slide rod 12 and the entire rotating plate 8 to begin to rotate around the axis. When the rotating plate 8 rotates to a certain angle, the leather on it slides off the balls under the action of gravity and falls onto the detection plate 5 on the detection table 3.

[0027] At this time, the motor 18 at the bottom of the inspection table 3 is started. The output of the motor 18 drives the rotating rod 19 at the axis of the inspection plate 5 through a pair of meshing bevel gears 20, causing the inspection plate 5 and the leather on it to rotate slowly. At the same time, the light 21 on the fixed plate 1 above the inspection table 3 provides illumination, allowing the operator to observe all sides of the leather while it is rotating and to sort the inspected leather. After the rotating plate 8 completes unloading, the cylinder 6 retracts, the drive block 7 moves in the opposite direction, causing the rotating plate 8 to first flip back to a horizontal position, and then slide horizontally back to its initial position, where it is supported by the support block 17 on the fixed plate 1, ready to receive the next piece of leather.

[0028] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the spirit and scope of the technical solutions of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
