Embodiment

[0020] see figure 1 and figure 2 , the wedge-type unwinding material shaft used in the production line of disposable sanitary products includes a fixed shaft 1, which is a stepped shaft, and the end of the large-diameter section is a flange for fixed installation on the frame; The small-diameter section is successively fitted with a left guide sleeve 2A, a right guide sleeve 2B, a spacer 6 and a compression spring 11. The spacer 6 is installed on the fixed shaft 1 through a key, and the spacer 6 is connected with the fixed shaft 1 through a key and cannot be rotated. , but it can slide axially along the fixed shaft when the hand wheel 8 is screwed in and out. The end of the small-diameter section of the fixed shaft 1 is connected to the handwheel 8 through thread fit. The inner end of the handwheel 8 is provided with a ring groove. touch.

[0021] Both the left guide sleeve 2A and the right guide sleeve 2B are flange-shaped, and the material is nylon. The small diameter e...

Abstract

The invention relates to a wedge-block-type unwinding shaft used in a production line of disposable hygienic products. In the invention, a fixed shaft is a stepped shaft, a small-diameter section of the fixed shaft is sequentially sheathed with two guide sleeves, a spacer bush and a compression spring, and an end part of the small-diameter section of the fixed shaft is in threaded connection witha hand wheel; one end of the compression spring is positioned in a circular groove of the hand wheel, and the other end of the compression spring is in contact with an end face of the spacer bush; locking sleeves are sheathed on small-diameter sections of the two guide sleeves, sleeves are sheathed outside the locking sleeves, four axial expansion pin grooves are uniformly distributed on each sleeve, and each expansion pin groove is internally equipped with an expansion pin; each expansion pin is in the shape of a wedge block, and an oblique plane of each expansion pin corresponds to each locking sleeve; and a taper sleeve is inserted between the locking sleeve and the sleeve which are positioned at one end adjacent to the spacer bush, a conical tube is arranged at one side of the taper sleeve, a cylindrical tube is arranged at the other side of the taper sleeve, and the conical surface of the conical tube of the taper sleeve is in contact with the oblique planes of the four expansionpins in a fit manner. The wedge-block-type unwinding shaft has the advantages of compact and delicate structure and reasonable design, and is convenient in use; unwinding resistance can be controlledby adjusting the hand wheel; and material coils can be fixed, assembled and disassembled quickly through the expansion pins.

Description

technical field [0001] The invention belongs to the technical field of disposable sanitary products production line equipment, and in particular relates to a material unwinding and fixing shaft on a disposable sanitary product production line. Background technique [0002] The material unwinding fixed shaft is an important device in the disposable sanitary product production line. Through this device, some special materials that need passive unwinding on the disposable sanitary product production line can be unrolled in a timely and stable manner according to production needs. At present, there are various structures of this device. Bearings are often used to connect the barrel and the fixed shaft. Resistance is applied to one side of the barrel, and the roll is manually fixed. It is troublesome to install and fix the material, the resistance adjustment range is small, and it is easy to jump during work. The unwinding is unstable, the constant tension of the material cannot ...
