Description

Roll changing device

Technical Field

The utility model relates to a paper treatment facility especially relates to a roll changing device.

Background

In the process of making blueprint paper, multiple layers of coating are required on white paper. Due to the limited length of each roll, when a roll is about to run out, a stop is required to replace the new roll. However, intermittent shutdown can cause a significant reduction in processing efficiency and damage to the equipment.

In order to solve the aforementioned problems, it is common in factories to prepare a new roll of paper from a previous roll of paper, and then to stick the end of the new roll of paper to the old roll of paper, when the previous roll of paper is about to run out, so as to achieve the purpose of uninterrupted winding of paper on the equipment.

The above prior art solutions have the following drawbacks: since the manual pasting operation of the paper roll depends on the pasting technology of workers, the pasting unevenness and even the wrinkles between the paper of the new paper roll and the paper of the old paper roll can be caused by carelessness, and the later coating operation is difficult. Moreover, two workers are needed for matching to manually paste the paper, and the difficulty is high.

The mounting table 1 is a cuboid plate-shaped structure, and can be fixed with paper processing equipment, or a self-locking universal wheel can be mounted at the bottom of the mounting table 1, and the position locking mode can be performed according to the field condition.

With reference to fig. 1 and 2, the abutting mechanism 2 includes a fixing plate 21, a conveying roller 22, and a vertical telescopic driving member 23. The fixing plate 21 is a rectangular plate body which is located on the upper surface of the mounting table 1, and the long side of the fixing plate 21 is parallel to the short side of the mounting table 1. A sliding groove 212 is fixed on the ground of the fixing plate 21, a rail 11 which can be inserted into the sliding groove 212 is fixed on the upper surface of the mounting table 1, and the sliding groove 212 can be sleeved outside the rail 11 from one end of the rail 11 and can slide along the rail 11. One long-side end face of the fixing plate 21 is provided with two transverse telescopic driving members 211 for driving the fixing plate 21 to slide along the rail 11. The transverse telescopic driving member 211 can be an electric cylinder, an air cylinder, a hydraulic cylinder and other conventional telescopic structures.

The conveying roller 22 is a rubber roller, the conveying roller 22 is disposed above the fixing plate 21, and the conveying roller 22 is parallel to the long side of the fixing plate 21. Bearing blocks are installed at two ends of the conveying roller 22, and one side of each bearing block, which deviates from the conveying roller 22, is fixed with the corresponding vertical telescopic driving piece 23. Two vertical flexible driving pieces 23 are along vertical setting, and vertical flexible driving piece 23 keeps away from bearing frame one side and is fixed in on fixed plate 21, and two vertical flexible driving pieces 23 and two horizontal flexible driving pieces 211 one-to-one set up simultaneously. The vertical telescopic driving member 23 may be an electric cylinder, an air cylinder, a hydraulic cylinder or other conventional telescopic structure.

In order to glue the paper of a new paper roll, a gluing mechanism 3 is additionally arranged on the upper surface of one end of the fixing plate 21, which is far away from the transverse telescopic driving piece 211. The gluing mechanism 3 comprises a vertical rod 31 vertically fixed on the fixing plate 21, a pipeline 32 fixed on the top of the vertical rod 31 and parallel to the conveying roller 22, a spray head 33 communicated with one side of the pipeline 32 facing the conveying roller 22 and uniformly distributed along the pipeline 32, and a gluing box 34 communicated with the pipeline 32 through a hose 4.
