Description

Technical Field

[0001] This utility model relates to the field of folding machine technology, specifically to an automatic roll-up and roll-down device for seamless folding of pad film in a folding machine. Background Technology

[0002] A bending machine, also known as a folding machine, produces creases on the surface of a sheet metal when it comes into contact with the lower die during the bending process. Some high-precision sheets, such as mirror sheets, need to avoid these creases during processing. Therefore, a thin film needs to be placed between the lower die and the sheet metal during the bending process. However, placing the film manually is not only inefficient, but the film is also easy to move, making bending inconvenient. Utility Model Content

[0003] The technical problem to be solved by this utility model is to provide an automatic roll-up and roll-down device for seamless edge folding of a folding machine, which addresses the shortcomings of the prior art.

[0004] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows: An automatic unwinding and rewinding device for seamless edge folding in an edge folding machine includes an unwinding bracket and a rewinding bracket, which are located on both sides of the lower die of the edge folding machine. The unwinding bracket is equipped with an unwinding wheel, and the rewinding bracket is equipped with a rewinding wheel. A plastic film is wound between the unwinding wheel and the rewinding wheel, covering the lower die. An unwinding bearing seat is mounted on the unwinding bracket, and an unwinding shaft is connected to the unwinding bearing seat. The unwinding wheel is connected to the unwinding shaft. A rewinding bearing seat is mounted on the rewinding bracket, and a rewinding shaft is connected to the rewinding bearing seat. The rewinding wheel is connected to the rewinding shaft. A motor bracket is mounted on the rewinding bracket, and a motor is mounted on the motor bracket. The output shaft of the motor is connected to the rewinding shaft.

[0005] Furthermore, the unwinding shaft passes through the unwinding bearing seat and is connected to a damping wheel. A fixed shaft is connected to the unwinding bracket, and a damping arm is connected to the fixed shaft. One end of the damping arm is connected to a roller, which contacts the damping wheel. A damping block is provided at the other end of the damping arm. The damping block is mounted on the unwinding bracket. The damping block has a mounting hole, and a spring and a spring top post are provided in the mounting hole. One end of the spring is connected to the damping arm, and an adjusting screw is installed on the damping block. The adjusting screw pushes the spring top post.

[0006] Furthermore, an adjusting rod is installed above the unwinding bracket and the winding bracket, and a guide wheel is installed above the adjusting rod, through which the plastic film passes.

[0007] Furthermore, the unwinding bracket and the winding bracket are machined with waist-shaped grooves, and the adjusting rod is connected to the waist-shaped grooves.

[0008] Furthermore, guide rods and guide wheel are mounted on the surfaces of the unwinding bracket and the winding bracket, and the plastic film passes between the guide rods and the guide wheel.

[0009] Compared with the prior art, the present invention provides an automatic film roll feeding and receiving device for crease-free folding in folding machines. This device can automatically feed and receive plastic film, which not only solves the crease problem, but also automatically feeds the film step by step according to the number of times the film can be used and the length of the workpiece to be folded. This replaces the manual work of feeding and changing the film, while ensuring the quality control of the folded product and improving the folding efficiency. Attached Figure Description

[0011] The technical solutions in the embodiments of this utility model will be clearly and completely described below.

[0012] like Figures 1-6 As shown, an automatic unwinding and rewinding pad film roll device for seamless edge folding in an edge folding machine includes an unwinding bracket 1 and a rewinding bracket 2. The unwinding bracket 1 and the rewinding bracket 2 are respectively located on both sides of the lower die 3 of the edge folding machine. An unwinding wheel 4 is provided on the unwinding bracket 1, and a rewinding wheel 5 is provided on the rewinding bracket 2. A plastic film 6 is wound between the unwinding wheel 4 and the rewinding wheel 5. The plastic film 6 covers the lower die 3. During edge folding, the unwinding wheel 4 unwinds the plastic film 6, placing it under the board material for edge folding, while the rewinding wheel 5 rewinds the plastic film 6.

[0013] The unwinding bracket 1 is equipped with an unwinding bearing seat 7, and an unwinding shaft is connected to the unwinding bearing seat 7. The unwinding wheel 4 is connected to the unwinding shaft, and a fixing screw 8 is installed at the end of the unwinding shaft to fix the unwinding wheel 4 to the unwinding shaft. A damping device is installed on the unwinding bracket 1. The damping device provides resistance during the unwinding process of the unwinding wheel 4 to prevent the plastic film 6 from unwinding.

[0014] In this embodiment, the unwinding shaft passes through the unwinding bearing seat 7 and is connected to a damping wheel 9. A fixed shaft is connected to the unwinding bracket 1, and a damping arm 10 is connected to the fixed shaft. One end of the damping arm 10 is connected to a roller 11, which contacts the damping wheel 9. The other end of the damping arm 10 is provided with a damping block 12. The damping block 12 has a mounting groove, and the damping block 12 is mounted on the unwinding bracket 1 by screws at the mounting groove. The damping block 12 has a mounting hole, and a spring 13 and a spring top post are provided in the mounting hole. One end of the spring 13 is connected to the damping arm, and a spring hole is machined at the end of the damping arm. One end of the spring 13 is connected to the spring hole. An adjusting screw 14 is installed on the damping block 12. The adjusting screw 14 pushes the spring top post, and the spring top post squeezes the spring 13, causing the damping arm to rotate and push the roller 11 to press against the damping wheel 9, thereby generating resistance during the unwinding process of the unwinding wheel 4.

[0015] The winding bracket 1 is equipped with a winding bearing seat 15, and a winding shaft is connected to the winding bearing seat 15. The winding wheel 5 is connected to the winding shaft, and a fixing screw 8 is also installed at the end of the winding shaft to fix the winding wheel 5 to the winding shaft. The winding bracket 2 is equipped with a motor bracket, and a motor 16 is installed on the motor bracket. The output shaft of the motor 16 is connected to the winding shaft. The motor 16 controls the rotation of the winding wheel 5 to wind up the plastic film 6.

[0016] Guide rods 17 and guide wheels 18 are installed on the surfaces of the unwinding bracket 1 and the winding bracket 2. Plastic film 6 passes through the guide rods 17 and guide wheels 18. An adjusting rod 19 is installed above the unwinding bracket 1 and the winding bracket 2. A guide wheel 20 is installed above the adjusting rod 19. Plastic film 6 passes through the guide wheel 20.

[0017] In this embodiment, the unwinding bracket 1 and the winding bracket 2 are machined with waist-shaped grooves 21. The waist-shaped grooves 21 are connected to the adjusting rod 19 by connecting screws 22 with handles. By setting the waist-shaped grooves 21, the height of the plastic film 6 on the guide wheel 20 is adjusted so that it can be adapted to the processing of different models of folding machines.

[0018] This utility model is not limited to the embodiments described. Those skilled in the art can still make some modifications or changes without departing from the spirit and scope of this utility model. Therefore, the scope of protection of this utility model shall be determined by the scope defined in the claims.
