Packaging paper unwinding device

Abstract

The invention provides a packaging paper unwinding device. The device comprises a supporting base, a center shaft and two bearing bases. The two bearing bases are oppositely fixed to the supporting base, a bearing is mounted in each bearing base, the two ends of the center shaft are arranged in the corresponding bearings in a penetrating manner, and the center shaft is in clearance fit with the inner ring of each bearing, so that the center shaft can be drawn out from the two bearings and can rotate relative to the bearings. The two bearing bases are placed on the supporting base, each bearingbase is internally provided with the bearing, the center shaft and the inner rings of the bearings are in clearance fit, when a paper roll needs to be unwound, the center shaft is pulled out, the paper roll is arranged on the center shaft in a sleeving manner along one end of the center shaft from the position between the two bearing bases, through pulling of the end of the paper roll, the paperroll is driven to roll to achieve unwinding, due to the fact that the center shaft is arranged in the two bearing bases in a penetrating manner, shaking or falling of the center shaft can be avoided,and convenience and stability of unwinding can be improved.

Description

technical field [0001] The invention relates to a wrapping paper unwinding device. Background technique [0002] After the stainless steel coil is processed, it needs to be packed with wrapping paper to protect the stainless steel coil. Usually wrapping paper rolls are unwound by an unwinding device. The existing unwinding device requires manual work or a hoist to place the central shaft of the paper roll on the open bearing seat, which is cumbersome to operate, and the central shaft has poor stability on the open bearing seat, and it is easy to shake or fall off, which is highly dangerous. In addition, because the wrapping paper roll is heavy, the existing unwinding device needs manpower to cooperate with rotating the paper roll to unwind, which is cumbersome to operate, time-consuming and laborious, and seriously affects work efficiency. Therefore, it is urgent to design a new wrapping paper unwinding device to solve the problems mentioned above. Contents of the invent...
