Description

Technical Field

[0001] The utility model belongs to the technical field of plate transport devices, in particular to a traceless plate turning machine. Background Art

[0002] During sheet processing, sheets sometimes need to be coated with glue to form semi-finished sheets. The glue on the sheets faces numerous challenges during transportation and turnover. Firstly, the fluidity of the glue must be precisely controlled to ensure uniform application across the sheets, avoiding problems such as overpenetration, sagging, and insufficient filling, which can affect bonding performance and the overall quality of the sheets. Furthermore, external factors such as vibration and impact during transportation and turnover can easily cause bubbles and voids in the glue, further weakening the bond.

[0003] On the other hand, the glue attached to the sheet forms a physical obstruction after curing, potentially blocking the sheet along the conveyor path, reducing conveying efficiency and increasing wear on conveying equipment. Furthermore, glue adhesion can alter the sheet's size, shape, or weight, affecting conveying accuracy and subsequent processing or assembly quality. Sheets are easily damaged during flipping, leaving marks that compromise the product's appearance and performance. Utility Model Content

When in use, the flip plate rack 31 is first flipped to the arrangement area of ​​the roller 21. After the plate is transported to the flip plate rack 31, the movable clamping plate 341 moves toward the fixed clamping plate 342 (the flip plate rack 31 can be driven to flip up slightly first) to clamp the plate. The flip plate rack 31 provides stable support for the plate. Movable clamping plates 341 and fixed clamping plates 342 are set on both sides to improve the clamping force and uniformity, so that the plate can be stably clamped and flipped under traceless conditions, thereby improving processing efficiency and product quality.

[0025] Furthermore, an auxiliary wheel 23 is fixedly connected to the middle of the conveying shaft 22, which can provide auxiliary support for the middle part of the plate and improve the flatness of the plate; in this embodiment, it can be transmitted through the gear 24 and the toothed belt and driven by a conventional motor.

[0026] Furthermore, a guide rail 332 is fixedly connected to the flip plate frame 31, and the guide rail 332 is slidably connected to a guide block 331. The guide block 331 is fixedly connected to the movable splint 341, ensuring that the movable splint 341 can move smoothly and accurately under the drive of the telescopic drive device 32, further improving the reliability of plate clamping and processing accuracy.

[0027] Furthermore, a flip seat 36 is installed on the frame 1, and the flip shaft 37 is rotatably connected to the flip seat 36. The flip drive device 35 includes a motor 351 and a reducer 352. The motor 351 is driven and connected to the reducer 352, and the reducer 352 is driven and connected to the flip shaft 37, providing a stable and controllable driving force for the flip shaft 37, ensuring the stable operation of the flip mechanism 3 and the accuracy of the flip.

[0028] Furthermore, the flipping drive device 35 is arranged at one end of the flipping shaft 37, and the other end of the flipping shaft 37 is fixedly connected to the brake disc 6. The frame 1 is also fixedly connected to the brake 7, and the brake 7 is operable to be frictionally connected to the brake disc 6, so that the flip mechanism 3 can respond quickly when it needs to stop or position, thereby improving the safety and operational flexibility of the equipment.

[0030] Furthermore, after flipping, the first cantilever 311 and the second cantilever 312 enter the gap where the conveying unit 2 is arranged, and the flipping mechanism can be operated to flip to below the conveying unit 2, thereby avoiding interference between the flipping plate frame 31 and the conveying unit 2 during the flipping process, and at the same time reducing the height of the equipment, which is convenient for operation and maintenance.

[0031] Furthermore, the first cantilever 311 and the second cantilever 312 are symmetrically arranged on the left and right, and the reinforcing connecting rod 313 is arranged at the outer ends of the first cantilever 311 and the second cantilever 312, so that the flip plate frame 31 is more balanced when subjected to force, thereby enhancing its stability; the arrangement of the reinforcing connecting rod 313 at the outer end further enhances the stability of the entire structure.

[0032] Furthermore, the roller 21 is a conical wheel, and the diameter of the conical wheel is set to be larger at the far end and smaller near the near end relative to the middle of the flip shaft 37, so that the plate can better fit the roller 21 during the conveying process, reducing friction and scratches. At the same time, it has a centering effect, which also helps to smoothly convey and flip the plate.

[0033] Furthermore, a water tank 4 is provided on the frame 1, and the roller 21 extends into the water tank 4. The roller 21 can rotate and use the water in the water tank 4 to wash away the glue attached to the surface, thereby further improving the traceless effect, which is particularly suitable for rubber plates.

The positioning member 51 and the straightening member 52 are respectively arranged on both sides of the movable clamping space and arranged in the installation area of ​​the conveying unit 2. The positioning member 51 and the straightening member 52 are both hinged to the frame 1. The straightening drive device 53 adopts a cylinder and is driven by a connecting rod assembly to be connected to the straightening member 52, so that it flips toward one side of the movable clamping space, thereby hitting or pushing the plate to move toward the alignment member 51 to achieve the straightening of the plate, which can better position the plate, facilitate clamping and flipping, and better position the plate to ensure that the plate is in the correct position before entering the movable clamping space, facilitate clamping and flipping, and further improve processing efficiency and product quality.

[0035] Specifically, the electric motor 351 may be a servo drive motor, and the telescopic drive device 32 may be a cylinder.
