Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of paper roll rewinding, in particular to a paper unloading device for a rewinding machine. Background Art
[0002] The 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 paper machine in sequence. After rewinding, the paper is made into finished paper for shipment. It has become a development trend in the papermaking machinery industry to use AC drive instead of DC drive for rewinders. The paper rolls rolled by the paper reel are relatively soft, and may be damaged or broken inside, with uneven edges on both sides and paper width. They cannot be directly used in paper processing or printing machines. Most types of paper (such as newsprint, letterpress printing paper, packaging paper, etc.) must be trimmed, slit, and spliced by the rewinder, and rewound on the paper roll core to form finished paper rolls of certain specifications and certain tightness requirements before they can be shipped. Since the mother roll is cut into multiple sets of finished paper, the equipment at each station of the rewinder moves frequently, and manual entry is required to conduct inspections and interventions, as well as equipment operation adjustments. In addition, many personal injury accidents have occurred in paper mills over the years, and most of them occurred at the rewinding station, with a very high risk factor. After the finished paper is rewound, the unloading platform takes over the finished paper and drops it to the drop roller plane. If an operator mistakenly enters the drop roller area due to weak safety awareness or other personal reasons, the unloading platform continues to work, and the roller rolls to the plane, it will cause serious squeezing and personal injury to the person entering, or even death on the spot. Summary of the invention

[0014] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0015] See also Figure 1-4 The utility model provides a technical solution: a paper unloading device of a rewinding machine, comprising a workbench 1, on which a rewinding mechanism 2 and a paper unloading mechanism 3 are arranged, and an arc-shaped slide rail 4 is arranged at the bottom end of the workbench 1.
[0016] The paper unloading mechanism 3 includes a rewinding bracket 31, on which a rotating shaft 32 is provided. The rotating shaft 32 is installed on brackets on both sides of the workbench 1, and the rotating shaft 32 is retractable. A rewinding paper roller 33 is provided on the rotating shaft 32. The rewinding bracket 31 is provided with a slide groove 38, and the rewinding paper roller 33 can slide in the slide groove 38. When the rewinding process is carried out, the rotating shaft 32 is in an extended state, and the rotating shaft 32 extends into the interior of the rewinding paper roller 33 and drives the rewinding paper roller 33 to rotate; when the rewinding process is completed, the rotating shaft 32 is retracted, and the rewinding paper roller 33 can slide down in the slide groove 38.
[0017] A slider 34 is provided at the bottom of the rewinding bracket 31, and the slider 34 is arranged in the arc slide rail 4. An arc motor 41 is provided in the arc slide rail 4. The slider 34 is arranged on the arc motor 41. Through the operation of the arc motor 41, the slider 34 is driven to make an arc motion on the arc slide rail 4, thereby driving the rewinding bracket 31 to swing with the rotating shaft 32 as the center. When the rewinding process is carried out, the rewinding bracket 31 is in a vertical state; when the rewinding process is completed, the rewinding bracket 31 moves toward the paper unloading platform to unload the paper roll.
[0018] The two ends of the arc-shaped slide rail 4 are provided with limit plates 42 , and the limit plates 42 are provided with buffer plates 43 . The buffer plates 43 are provided with a plurality of buffer rods, so as to play a buffering role when the slider 34 slides to the two ends of the arc-shaped slide rail 4 to protect the equipment.
[0019] The rewinding mechanism 2 includes a paper winding roller 21, a plurality of paper pressing rollers 22 are arranged behind the paper winding roller 21, a plurality of paper guide rollers 23 are arranged behind the plurality of paper pressing rollers 22, a rewinding bottom roller 24 is arranged behind the plurality of paper guide rollers 23, and both ends of the paper winding roller 21, the paper pressing roller 22 and the paper guide roller 23 are fixed on the brackets on both sides of the workbench 1.
[0020] The two ends of the rewinding bottom roller 24 are connected to the rewinding bracket 31 through a connecting rod 25, and a spring is arranged inside the connecting rod 25. The rewinding bottom roller 24 is tangent to the paper roll on the rewinding paper roller 33 through the action of the spring to ensure that the rewinding bottom roller 24 can resist the paper roll wound on the rewinding paper roller 33.
[0021] A paper unloading platform 35 is provided at the end of the arc-shaped slide rail 4, and a placement platform 36 is provided between the arc-shaped slide rail 4 and the paper unloading platform 35. A plurality of buffer strips 37 are provided on the paper unloading platform 35. When the rewinding paper roller 33 slides to the bottom of the slide groove 38, it separates from the rewinding bracket 31 and falls into the placement platform 36. The staff can pull out the rewinding paper roller 33 only after confirming that the quality of the paper roll is correct, and then push the paper roll down. Through the buffering effect of the plurality of buffer strips 37 on the paper unloading platform 35, the paper roll falls slowly, and there is no safety hazard throughout the process. A cart can be placed behind the paper unloading platform 35 for subsequent collection and transportation of the paper roll.
[0022] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
