Rewinding mechanism for rechecking machine

Abstract

The invention provides a rewinding mechanism for a rechecking machine. The rewinding mechanism is characterized by comprising a rack, a transverse arranged U-shaped positioning groove, a power mechanism and a rotating shaft mechanism, wherein an output shaft of the power mechanism is provided with a clutch; the rotating shaft mechanism comprises a paper tube rotating shaft main body, a bearing connecting shaft, a bearing component and a transmission shaft with clutching teeth on the outer surface; the bearing component comprises a tubular bearing pedestal and a bearing; the bearing connectingshaft is connected to the bearing in a penetration manner; the transverse arranged U-shaped positioning groove is connected to a set screw in a penetration manner; the clutch comprises a movable sleeve which rotates along with the output shaft and can move forwards and backwards; and transmission teeth engaged with the clutching teeth on the transmission shaft are arranged in the inner cavity of the movable sleeve. Compared with the prior art, the rewinding mechanism has the advantages of being capable of substantially lowering noise and causing rechecking environments to be friendly.

Description

Technical field: [0001] The invention relates to a winding technology. Background technique: [0002] After the existing plastic film is produced, it needs to be rolled on a paper tube while inspecting its quality. In this process, the rolled plastic film needs to be continuously rolled away, and then replaced with a new paper tube. One technology uses two pairs of rollers to support the roller, the paper tube is sleeved on the roller, one end of the roller is equipped with a gear, and the gear meshes with the output gear of the power mechanism. The gear on the roller is movably positioned to the output gear, so that it meshes with the output gear to obtain rotation power, and at the same time, it is convenient to remove the roller after the plastic film is rolled to install the paper tube. In this technology, because the gear on the roller needs to move to the output gear to engage with it, it is determined by the nature of the roller transmission. When the roller rotates, the ...

Problems solved by technology

In this technology, because the gear on the roller needs to move to the output gear to mesh with it, it is determined by the nature of the roller transmission. When the roller rotates, the axis center will often deviate. In order to mesh smoothly, the roller The connection between the upper gear and the output gear should not be too precise, otherwise it will not be easy to carry out the meshing operation, which will lead to a large meshing gap between the roller shaft and the output gear. Due to the large meshing gap, when the output gear drives the gear on the roller to rotate, it will produce a lot of noise, especially when it is turned to the adjacent winding core

Its angular velocity is very fast (because the linear velocity is constant), and the noise at this time is particularly large, which has a great impact on the re-inspection environment
