Description

Technical Field

[0001] This utility model relates to a leather processing equipment, and more particularly to a leather edge-wrapping machine. Background Technology

[0002] Existing leather wrapping machines use a twisting belt to wrap the long edge, which results in an insufficiently tight and flat wrapping, with gaps and bulges. If the short edge wrapping method is used, a pressure plate is needed to hold the material down for wrapping, which hinders the wrapping action of the wrapping plate, especially when wrapping irregular edges. Utility Model Content

[0003] In view of the technical problems existing in the background art, the present utility model aims to provide a leather edge-wrapping machine, which is designed to use a material transfer robot in conjunction with an edge-wrapping mechanism to perform edge wrapping.

[0004] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: This type of leather wrapping machine includes a conveying mechanism, which is equipped with a wrapping mechanism. The conveying direction of the conveying mechanism is defined as transverse. The conveying mechanism is also equipped with a positioning component. The wrapping mechanism and the positioning component are arranged sequentially along the transverse direction. A material transfer robot is connected between the wrapping mechanism and the positioning component. The positioning component includes a longitudinally moving push plate. The wrapping mechanism includes a wrapping plate, which moves longitudinally and is raised and lowered.

[0005] In this scheme, the pusher moves longitudinally to push the material into place, and then the material handling robot picks up the material and places it on the conveying mechanism at the edge-sealing mechanism. The edge-sealing mechanism then completes the edge-sealing process.

[0006] Preferably, the conveying mechanism includes a suction conveyor belt.

[0007] In this solution, the suction conveyor belt draws in materials from below, which does not obstruct the movement of the edge-sealing plate, especially when sealing irregular edges.

[0008] Preferably, the material transfer robot includes a movable frame, a mounting frame, and a suction frame connected together. The movable frame is laterally movable above the conveying mechanism, the mounting frame is vertically movable below the movable frame, two sets of suction frames are longitudinally movable and adjustable below the mounting frame, and multiple material transfer nozzles are laterally movable and adjustable on the suction frames.

[0009] In this design, the longitudinal movement of the suction rack and the lateral movement of the transfer nozzle can adapt to materials of different sizes, ensuring reliable adsorption of the material body without excessive sagging at the edges.

[0010] Preferably, there are two sets of push plates, which are mounted on the mounting base via mounting arms, and the mounting base is longitudinally movable.

[0011] In this scheme, two sets of push plates work together to push the materials into place, ensuring accurate positioning.

[0012] Preferably, the edge banding plate is mounted on the mounting plate via a connecting arm, the mounting plate is vertically mounted on the movable seat, and the movable seat is longitudinally movable.

[0013] In this scheme, the edge binding action is broken down into three steps: the edge binding board rises to erect the edge, the edge binding board moves longitudinally to fold the edge, and the edge binding board descends to press the edge.

[0014] Preferably, the movable seat has a square hole and a lifting power source. The lifting power source and the mounting plate are respectively disposed on both sides of the movable seat. The lifting power source is driven by a transmission block, which passes through the square hole and is connected to the mounting plate.

[0015] In this design, the square hole wall can limit the movement of the transmission block, thereby limiting the lifting and lowering of the edge banding plate.

[0016] Preferably, a brush is provided below the edge banding plate, and the top and side surfaces of the edge banding plate are curved.

[0017] In this solution, when the edge banding is moved longitudinally and folded, the brush can brush the side edge to remove air bubbles, and the curved transition avoids damage to the side surface of the edge banding when the edge is upright.

[0018] Preferably, the conveying mechanism is further equipped with a corner-beating mechanism, which is arranged sequentially in the transverse direction. The corner-beating mechanism includes a corner-beating wheel, a positioning plate, a pressure block, and a mounting beam. Two sets of mounting beams are arranged to move longitudinally. The positioning plate is arranged on the mounting beam, the pressure block is lifted and lowered on the mounting beam, and the corner-beating wheel is arranged to move longitudinally on the mounting beam. In the transverse direction, the corner-beating wheel is misaligned with the positioning plate and the pressure block.

[0019] In this scheme, the installation beam moves longitudinally, the positioning plate pushes the material to align, the pressure block descends to press down the wrapped side, and the corner rollers move longitudinally to flatten the side corners.

[0020] Preferably, the mounting beam is provided with a sliding seat for lateral movement adjustment, the positioning plate is disposed on the sliding seat, the positioning plate is connected to a connecting plate, the connecting plate is provided with a pressing cylinder, the pressing cylinder is drivenly connected to the pressing block, the sliding seat is provided with a corner-cutting cylinder, the corner-cutting cylinder is drivenly connected to a drive plate, the drive plate is provided with an adjusting seat for lifting adjustment, the adjusting seat is provided with a fixed seat for lateral movement adjustment, and the fixed seat is equipped with the corner-cutting wheel.

[0021] In this design, the lifting adjustment seat and the lateral movement adjustment fixed seat are adapted to cornering materials of different thicknesses and sizes. The positioning plate connects to the connecting plate, resulting in a compact structure.

[0022] Preferably, after the material transfer robot descends to its position, the edge banding plate first rises and then moves horizontally.

[0023] In this scheme, the edge-sealing plate rises to form a vertical edge, and the suction conveyor belt works in conjunction with the material transfer robot to reliably fix the material.

[0024] The beneficial effects of this utility model are as follows: after the pusher plate moves longitudinally to straighten the material, the material transfer robot picks up the material and places it on the conveyor mechanism at the edge-sealing mechanism, and the edge-sealing mechanism completes the edge-sealing; the edge-sealing plate rises to straighten the edge, and the suction conveyor belt, in conjunction with the material transfer robot, reliably fixes the material. Therefore, this utility model has substantial features and progress compared with the prior art. Attached Figure Description

[0037] See appendix Figure 1-4 In one embodiment of this invention, a leather wrapping machine is provided, including a conveying mechanism 1, which is equipped with a wrapping mechanism 2. The conveying direction of the conveying mechanism 1 is defined as transverse, and the conveying mechanism 1 includes a suction conveyor belt.

[0038] The conveying mechanism 1 is also equipped with a positioning component 3. The edge-binding mechanism 2 and the positioning component 3 are arranged sequentially in the horizontal direction. A material transfer robot 4 is connected between the edge-binding mechanism 2 and the positioning component 3. The material transfer robot 4 includes a moving frame 7, a mounting frame 8 and a suction frame 9 connected to each other. The moving frame 7 is arranged horizontally above the conveying mechanism 1. The mounting frame 8 is arranged vertically below the moving frame 7. Two sets of suction frames 9 are arranged vertically below the mounting frame 8. Multiple material transfer nozzles 10 are arranged horizontally on the suction frames 9.

[0039] The positioning component 3 includes a longitudinally movable push plate 5, which consists of two sets. The push plate 5 is mounted on the mounting base 12 via a mounting arm 11, and the mounting base 12 is longitudinally movable.

[0040] The edge-binding mechanism 2 includes an edge-binding plate 6, with a brush 19 below the edge-binding plate 6. The top and side surfaces of the edge-binding plate 6 are curved. The edge-binding plate 6 is mounted on the mounting plate 14 via a connecting arm 13. The movable seat 15 is longitudinally movable. The movable seat 15 has a square hole 16 and a lifting power source 17. The lifting power source 17 and the mounting plate 14 are respectively located on both sides of the movable seat 15. The lifting power source 17 is driven by a transmission block 18. The transmission block 18 passes through the square hole 16 and is connected to the mounting plate 14. After the material transfer robot 4 descends to its position, the edge-binding plate 6 first rises and then moves horizontally.

[0041] In this embodiment, the face paper starts from the feed end of the suction conveyor belt, and sequentially goes through the papering board, wrapping the long side, and corner trimming. After corner trimming, it is transferred by the robot arm for longitudinal conveying and the short side is wrapped. The papering board is a mature technology. When wrapping the long side, two sets of push plates 5 first push the material longitudinally to align it. The mounting frame 8 descends, the material transfer nozzle 10 absorbs the material, the mounting frame 8 rises, the moving frame 7 moves laterally to the edge wrapping mechanism 2, the mounting frame 8 descends into place, the two side edge wrapping plates 6 rise to stand up the side, the two side edge wrapping plates 6 move longitudinally to fold the side inward, and at the same time the material transfer robot arm 4 rises. After the two side edge wrapping plates 6 move longitudinally into place, they descend to complete the edge wrapping. Then the edge wrapping plates 6 rise.

[0042] Among them, the edge banding plate 6 can also move diagonally after rising (falling and moving longitudinally). Replacing the edge banding plate 6 changes the edge banding contour of the edge banding plate 6 to adapt to irregular edge banding. The material transfer frame is guided by a slide rail slider and is driven by a transverse motor through a synchronous belt. The mounting frame 8 is driven by a lifting motor through a screw and is set with guidance. The movement adjustment method of the suction frame 9 and the material transfer nozzle 10 is specifically a sliding positioning connection, which is a mature technology. The mounting seats 12 on both sides are driven by the same longitudinal motor through a screw and are set with guidance. The moving seat 15 is also driven by another longitudinal motor through a screw and is set with guidance. The lifting power source 17 is a motor, which drives the transmission block 18 through a screw.

[0043] In other alternative implementations, a chain can be used to drive a pusher to push the material, or the material can be lifted up during the descent of the transfer robot 4.

[0044] See appendix Figure 5-7The conveying mechanism 1 is also equipped with a corner-beating mechanism 23, which is arranged sequentially in the transverse direction. The corner-beating mechanism 23 includes a corner-beating wheel 24, a positioning plate 25, a pressure block 26, and a mounting beam 27. The two sets of mounting beams 27 are arranged longitudinally. In the transverse direction, the corner-beating wheel 24 is misaligned with the positioning plate 25 and the pressure block 26. A sliding seat 28 is provided on the mounting beam 27 for transverse movement adjustment. The positioning plate 25 is arranged on the sliding seat 28. The positioning plate 25 is connected to a connecting plate 29. A pressing cylinder is provided on the connecting plate 29. The pressing cylinder is drivenly connected to the pressure block 26. A corner-beating cylinder 31 is provided on the sliding seat 28. The corner-beating cylinder 31 is drivenly connected to a drive plate 32. An adjusting seat 33 is provided on the drive plate 32 for lifting adjustment. A fixed seat 34 is provided on the adjusting seat 33 for transverse movement adjustment. The corner-beating wheel 24 is installed on the fixed seat 34.

[0045] In this embodiment, the suction conveyor belt transports the material to the corner-cutting mechanism 23, the mounting beam 27 moves longitudinally, the two side positioning plates 25 push the material together, the edge-pressing cylinder drives the pressing block 26 to descend and press the side, and the corner-cutting cylinder 31 drives the corner-cutting wheel 24 to move longitudinally to complete the corner-cutting. The papering board, wrapping the long side and corner-cutting can be completed on a single suction conveyor belt, resulting in strong production continuity. The sliding seat 28 and the mounting beam 27 are connected by a sliding rail slider. The adjustment method of the adjusting seat 33 and the fixed seat 34 is a sliding positioning connection.

[0046] The above description represents the preferred embodiment of this utility model. It should be noted that the scope of protection of this utility model is not limited thereto. For those skilled in the art, various improvements, modifications, or equivalent substitutions can be made without departing from the equivalent inventive concept disclosed in this utility model, and these can also be considered as part of the scope of protection of this utility model.
