Technical Field

The utility model relates to the technical field of rewinding machines, in particular to an anti-deviating adhesive tape rewinding machine.

Background Art

Rewinder is a special equipment for paper, mica tape and film. Its purpose is to rewind the paper rolls (called base paper rolls) produced by the papermaking machine in sequence. After rewinding, the paper is made into finished paper and shipped out. Rewinder is generally used for rewinding, slitting and splitting mica tapes, paper and films. It is often used to slit wide rolls and plays an important role in subsequent re-slitting. It is a special equipment for paper, mica tape, film and tape.

When the existing rewinding machine is winding the tape, the product on the rewinding roller often has insufficient pulling force on the tape, which often causes wrinkles to form when the tape is wound, and the tape is easily loose when it is wound. At the same time, the position of the tape may shift during rewinding, resulting in a poor effect of the rubber ring after rewinding. Therefore, the utility model provides an anti-deviating tape rewinding machine.

DETAILED DESCRIPTION

Referring to Figures 1-3, the utility model provides a technical solution: an anti-deviation tape rewinding machine, including a processing plate 1, one end of the processing plate 1 is fixedly connected to two fixed columns A2, the upper ends of the two fixed columns A2 are rotatably connected to a conveying roller 3, one side of the fixed column A2 is provided with a pressing device, and the side of the pressing device away from the fixed column A2 is provided with two fixed columns B, the lower ends of the two fixed columns B14 are fixedly connected to the surface of the processing plate 1, and the upper ends of the two fixed columns B14 are rotatably connected to an auxiliary roller 15, the side of the fixed column B14 away from the pressing device is provided with two fixed columns C16, the lower ends of the two fixed columns C16 are fixedly connected to the surface of the processing plate 1, and the upper ends of the two fixed columns C16 are rotatably connected to a bidirectional screw rack 17, and the bidirectional screw Two limit plates 18 are threadedly connected to the surface of the frame 17, and one end of the processing plate 1 away from the fixed column A2 is fixedly connected to two mounting plates 19. A rewinding roller 21 is rotatably connected between the two mounting plates 19. One end of the rewinding roller 21 passes through the side wall of the mounting plate 19 and is installed with a motor 20. When the tape needs to be reeled up, one end of the tape can be passed through between the two conveying rollers 3 first, and then connected to the rewinding roller 21. Then, the pressing device is turned on to press down and stretch the surface of the tape, so that the surface of the tape becomes taut during rewinding, and there are no wrinkles on the surface of the rubber ring after rewinding. Then, the bidirectional screw frame 17 is rotated to make the two limit plates 18 on the surface of the bidirectional screw frame 17 close to each other, so as to limit the tapes of different widths and avoid the position of the tape from shifting during rewinding.

1 and 2, in this embodiment: the pressing device includes a pressing frame 7, the lower end of the pressing frame 7 is fixedly connected to the surface of the processing plate 1, and the upper end of the pressing frame 7 is installed with an electric push rod 8, the output end of the electric push rod 8 passes through the upper end of the pressing frame 7 and is fixedly connected with a fixed plate 9, both ends of the fixed plate 9 are slidably connected with a sliding column 10, and the lower end of the sliding column 10 is fixedly connected with a roller frame 12, a spring 11 is provided between the connection between the roller frame 12 and the sliding column 10, and the inner wall of the roller frame 12 is fixedly connected with a roller frame 13 , turn on the electric push rod 8, the output end of the electric push rod 8 drives the sliding columns 10 on both sides of the fixed plate 9 to move downward, and the sliding columns 10 drive the roller frame 13 in the roller frame 12 to move downward during the downward movement. When the roller frame 13 is squeezed with the surface of the tape, the roller frame 12 is pushed to squeeze the spring 11 upward. The elastic deformation of the spring 11 can prevent the roller frame 13 from excessively squeezing the surface of the tape, protecting the surface of the tape from damage, and at the same time making the surface of the tape tight during winding, and there is no wrinkle on the surface of the rubber ring after winding.

Referring to Figures 1 and 3, specifically, the side walls of the two fixed columns A2 are fixedly connected with fixed blocks 4, one side of the two fixed blocks 4 is rotatably connected with a movable rod 5, and a supporting roller 6 is rotatably connected between the two movable rods 5. By rotating the movable rod 5, the surface of the tape can be supported by the supporting roller 6, so that the winding process is smoother. One side of the two mounting plates 19 is fixedly connected with a supporting block 22, and two limiting rollers 23 are rotatably connected between the two supporting blocks 22. By limiting the surface of the tape by the two limiting rollers 23, wrinkles on the surface of the tape can be eliminated, so that the effect of the rubber ring after winding is better. A rotating frame 24 is rotatably connected between the two support blocks 22, and a cutting knife 25 is fixedly connected to the surface of the rotating frame 24, and the cutting knife 25 is located above the limiting roller 23. When the tape is wound, the rotating frame 24 can be rotated, and the rotating frame 24 drives the cutting knife 25 to cut the tape.

Working principle: when the tape needs to be rolled up, one end of the tape can be passed through the two conveyor rollers 3 first, and then the movable rod 5 can be rotated to support the surface of the tape through the support roller 6 to make the rolling process smoother. Then, one end of the tape is connected to the rewinding roller 21, and then the electric push rod 8 is turned on. The output end of the electric push rod 8 drives the sliding columns 10 on both sides of the fixed plate 9 to move downward. During the downward movement of the sliding column 10, the roller frame 13 in the roller frame 12 is driven to move downward. When the roller frame 13 is squeezed with the surface of the tape, the roller frame 12 is pushed upward. The extrusion spring 11 can prevent the roller frame 13 from over-extruding the tape surface through elastic deformation of the spring 11, thereby protecting the tape surface from damage. At the same time, it can also make the tape surface become tight during winding, and there will be no wrinkles on the rubber ring surface after winding. Then, the bidirectional screw frame 17 is rotated to make the two limit plates 18 on the surface of the bidirectional screw frame 17 close to each other, thereby limiting the position of tapes of different widths to prevent the tape position from shifting during winding. When the tape is wound, the rotating frame 24 can be rotated to drive the cutting knife 25 to cut the tape.
