Description

Technical Field

[0001] The utility model relates to the technical field of paper towel production, in particular to an unwinding device for roll paper production. Background Art

[0002] With the development of society and the advancement of science and technology, automated production has replaced manual production methods. In the automated production process of paper towels, the unloading device for raw material roll paper is an indispensable equipment.

[0003] However, the existing raw material roll paper unloading device has a single function and cannot fix the roll paper wheels of different lengths well. Each time the roll paper wheel is replaced, the matching connecting shaft needs to be replaced, which has low work efficiency and requires a long shutdown time.

[0004] For example, patent CN215625527U discloses a paper roll unloading device. When the device is in use, due to the different specifications of the paper roll wheels, the inner diameters of the paper roll shafts are different. The inner diameters of the different roll shafts can only be adjusted through the through holes. Since the position of each through hole is fixed, it cannot adapt to multiple specifications. The paper roll wheels of different specifications can only be selected according to the through holes that have been opened, which makes it less flexible. Utility Model Content

[0005] The utility model aims to solve the problems in the background technology and proposes an unwinding device for roll paper production.

DETAILED DESCRIPTION

[0022] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention.

[0023] Reference Figure 1-3 A reeling device for roll paper production includes a reel 1, extension columns 5 are fixedly installed at both ends of the reel 1, assembly seats 2 are fixedly installed at both ends of the reel 1, multiple electric telescopic rods 3 are fixedly installed on the side of each assembly seat 2, and multiple electric telescopic rods 3 with corresponding positions are jointly installed with baffles 4, each baffle 4 is in contact with the outer side of the reel 1, and each baffle 4 is against the paper reel 6, and the paper reel 6 is sleeved on the outer side of the reel 1, and the baffle 4 is driven by the electric telescopic rod 3 to clamp and fix the paper reel 6.

[0024] A plurality of through slots 7 are symmetrically provided on the outer side of the winding roller 1, each through slot 7 is passed through a pressure plate 8, and each pressure plate 8 is against the inner wall of the paper reel 6, a driving mechanism is provided in the winding roller 1, and the driving mechanism drives each pressure plate 8 to move outward, the driving mechanism includes a motor 12, a first fixed disk 9 and a second fixed disk 10 are respectively fixedly installed in the winding roller 1, and the motor 12 is fixedly installed on the first fixed disk 9, and a threaded rod 13 is connected to the output shaft of the motor 12, and the other end of the threaded rod 13 is rotatably connected to the second fixed disk 10, a nut 14 is threadedly connected to the threaded rod 13, and the rotation of the threaded rod 13 drives the nut 14 to move.

[0025] A plurality of connecting rod mechanisms are provided on the nut 14, and each connecting rod mechanism is connected to the corresponding pressure plate 8. The connecting rod mechanism includes a rotating seat 15, and the rotating seat 15 is fixedly mounted on the outside of the nut 14. A connecting rod 11 is rotatably connected to the rotating seat 15. A slide seat 17 is slidably connected to the side of each pressure plate 8. A slide groove 16 is provided on the outside of each pressure plate 8, and the slide seat 17 is slidably connected in the corresponding slide groove 16, and the other end of the connecting rod 11 is rotatably connected to the corresponding slide seat 17. It is worth mentioning that the slide seat 17 is U-shaped. When the connecting rod 11 is moved to a horizontal state through the nut 14, the device is in a state where it can clamp the paper roll 6 of the maximum specification, and then the connecting rod 11 is limited by the slide seat 17 to keep it in a horizontal state.

[0026] A plurality of correction mechanisms are provided on the side of the second fixed disk 10, and each correction mechanism is connected to the pressure plate 8 at the corresponding position. The correction mechanism includes a fixed seat 19, which is fixedly installed on the side of the second fixed disk 10. A telescopic support 18 is fixedly installed on the side of the fixed seat 19, and the other end of the telescopic support 18 is fixedly installed on the side of the pressure plate 8 at the corresponding position. The pressure plate 8 is assisted in alignment by the telescopic support 18 to keep it in the same horizontal direction as the roller 1.

[0027] When the utility model is used, the staff first sets the paper roll to be unwound on the outside of the roller 1, and then rotates and clamps the extension columns 5 fixedly installed at both ends of the roller 1 on the fixing mechanism of the external device. Since the fixing mechanism is a prior art, it will not be described in detail here, and then the whole device is vacated.
