Description

Novel chock plug press clamp device

Technical Field

The utility model relates to the technical field of papermaking industry, in particular to a novel plug pressing and clamping device.

Background

The raw paper roll produced by the paper machine enters a storage warehouse after being rewound and cut, and after being subjected to subsequent processing station sections or cutting or packaging. In order to keep the paper roll in good shape during storage and transportation without influencing subsequent processing, a plug made of wood or plastic materials is generally needed to be plugged into a paper core tube in the center of the paper roll so as to prevent the situation that the paper rolls are mutually extruded or the paper core collapses after the paper core at the outer edge of the paper roll is wetted. At present, paper factories all adopt manual operation: according to the paper core specification of the paper roll, a proper paper core plug is selected, the paper core pipe is plugged with the plug in a lateral standing mode, and then the end of the plug is knocked by a hammer, so that the end face of the plug is ensured not to protrude out of the end face of the paper roll.

In application number: 202020009850.9, in the paper roll paper core plugging and clamping device, a pneumatic control swing arm is adopted to lift so as to conveniently adjust the lifting speed and strength; the chain transmission mode is adopted for clamping, so that the clamping force can be controlled according to actual conditions; the rotary central shaft of the left-right swinging mechanism adopts a self-made bearing seat matched with a tapered roller bearing, and can bear larger axial radial load. Experiments prove that the equipment can completely replace manual work, saves a great amount of human resources for paper enterprises, and improves the automatic production capacity of the paper enterprises. However, during practical use, the following disadvantages are found: 1. the clamping arm is a pneumatic swing mechanism, is easy to deform, and the whole stress point is a rotating point, so that loosening is easy to occur, and the choke plug is not pressed tightly; 2. the clamping arm is a swinging mechanism, so that the diameter range of the paper roll is limited relatively large; 3. a roll of paper having a width of less than 500mm cannot be pressed in.
