Background

When sealing elements such as sealing strips, sealing gaskets and the like are produced, a cutting machine is required to cut raw materials into strips with required widths; in the slitting process, the slitter needs to use a winding shaft to wind the slit material strips. In the prior art, a sub-scroll generally adopts an air inflation shaft, an air bag is arranged in the air inflation shaft, and when the air bag is inflated, the diameter of the air inflation shaft is increased, so that an inner bushing of a material roll can be inflated; when the gas in the air bag is discharged, the diameter of the air expansion shaft is reduced, and the rolled material can be rolled down.

Although the inflatable shaft is convenient to use, the inflatable shaft is not suitable for working environment without an air source because the inflatable shaft needs the air source when working.

Disclosure of Invention

Therefore, the utility model aims to provide a winding shaft device to solve the technical problem of winding materials cut by a slitting machine under the condition of no air source.

The winding shaft device comprises a middle shaft assembly and a winding Zhang Zhou assembly;

the middle shaft assembly comprises a shaft rod, a left conical supporting sleeve and a right conical supporting sleeve which are sleeved on the shaft rod and are in sliding fit with the shaft rod, a hand wheel for pushing the right conical supporting sleeve to move to the left side of the shaft rod, and a limiting piece arranged on the shaft rod and used for preventing the left conical supporting sleeve from moving to the left side, wherein the hand wheel is in threaded fit with the shaft rod;

the folding shaft assembly comprises a folding shaft Zhang Zhoutao and a spring folding ring, the folding shaft sleeve is composed of a plurality of shaft flaps which are arranged in an array mode along the circumferential direction, the left end of the folding shaft sleeve Zhang Zhoutao is provided with a conical hole matched with a left conical supporting sleeve, the right end of the folding shaft sleeve Zhang Zhoutao is provided with a conical hole matched with a right conical supporting sleeve, and annular grooves for installing the spring folding ring are respectively formed in the left end and the right end of the folding shaft sleeve Zhang Zhoutao.

Further, the winding shaft device also comprises a universal coupling connected with the right end of the shaft lever.

Further, the limiting piece is a screw.

The utility model has the beneficial effects that:

according to the winding shaft device, the right conical supporting sleeve is pushed by the hand wheel to move left to expand the winding shaft sleeve, the elastic force of the elastic winding ring is used for winding Zhang Zhoutao, and the winding shaft device does not depend on an air source during working and has better adaptability.

Detailed Description

The utility model is further described below with reference to the drawings and examples.

As shown in the figure, the winding shaft device of the embodiment comprises a middle shaft assembly and a winding Zhang Zhou assembly.

The middle shaft assembly comprises a shaft rod 1, a left conical supporting sleeve 2 and a right conical supporting sleeve 3 which are sleeved on the shaft rod and are in sliding fit with the shaft rod, a hand wheel 4 for pushing the right conical supporting sleeve to move to the left side of the shaft rod, and a limiting piece 5 arranged on the shaft rod and used for preventing the left conical supporting sleeve from moving to the left side, wherein the hand wheel is in threaded fit with the shaft rod. In this embodiment, the limiting member 5 is a screw; of course, in different embodiments, the limiting member 5 may also be in other forms such as a limiting pin or a limiting ring.

The folding shaft assembly comprises a folding shaft sleeve 6 and an elastic folding ring 7, the folding shaft sleeve is composed of a plurality of shaft flaps which are arranged in an array mode along the circumferential direction, the left end of the folding shaft sleeve Zhang Zhoutao is provided with a conical hole matched with a left conical supporting sleeve, the right end of the folding shaft sleeve Zhang Zhoutao is provided with a conical hole matched with a right conical supporting sleeve, and annular grooves for installing the elastic folding ring are respectively formed in the left end and the right end of the folding shaft sleeve Zhang Zhoutao.

In this embodiment, when the diameter of the winding shaft sleeve 6 needs to be increased, the right conical supporting sleeve is pushed to move left by the hand wheel, and the axial flap of the winding shaft sleeve 6 is pushed to move radially outwards by the left movement of the right conical supporting sleeve, so that the diameter of the winding shaft sleeve 6 is increased. When the diameter of the telescopic shaft sleeve 6 needs to be contracted and reset, the hand wheel is rotated to enable the telescopic shaft sleeve 6 to move rightwards, at the moment, the elastic telescopic ring 7 contracts under the elasticity, and the elastic telescopic ring 7 contracts to push the telescopic shaft sleeve 6 to move inwards in the radial direction, so that the diameter of the telescopic shaft sleeve 6 is contracted and reset. The winding shaft device in the embodiment does not depend on an air source in working and has good adaptability.

As an improvement of the above embodiment, the winding shaft device further comprises a universal coupling 8 connected with the right end of the shaft lever. The right-hand member of axostylus axostyle 1 passes through universal joint and is connected with the rolling motor in this improvement, is provided with bearing 9 on the left end of axostylus axostyle, and bearing 9 sets up in the U-shaped groove in the frame during the installation, sets up limit structure to the bearing in the U-shaped groove. When the material roll on the winding shaft sleeve 6 needs to be dismounted, the shaft lever 1 can be rotated around the joint shaft of the universal coupling 8, so that the left end of the shaft lever is separated from the frame, and the material roll can be conveniently dismounted from the winding shaft device.

Finally, it is noted that the above embodiments are only for illustrating the technical solution of the present utility model and not for limiting the same, and although the present utility model has been described in detail with reference to the preferred embodiments, it should be understood by those skilled in the art that modifications and equivalents may be made thereto without departing from the spirit and scope of the technical solution of the present utility model, which is intended to be covered by the scope of the claims of the present utility model.
