Description

Unreeling rotating shaft

Technical Field

The utility model relates to the technical field of packaging machinery, in particular to unreel axis of rotation.

Background

In the color printing industry, the unreeling shaft commonly used at present is a paper shaft. The reliability of continuous long-time work of the paper unreeling shaft is poor, and after the paper unreeling shaft works continuously for a long time, the situations of slight deformation, poor toughness, easy damage and the like caused by high temperature easily occur, so that the production efficiency is influenced. Therefore, it is necessary to design a new unwinding shaft with long-term operational reliability.

SUMMERY OF THE UTILITY MODEL

In view of the above, the present invention is directed to an unwinding rotary shaft capable of using ultrasonic waves and laser light simultaneously as diagnostic and therapeutic media.

The purpose of the utility model is realized through the following technical scheme:

an unreeling rotating shaft comprises a shaft body, wherein two end faces of the shaft body are respectively connected with a joint, and the shaft body is detachably connected with the two joints;

one end of each of the two joints, which is far away from the shaft body, is provided with a connecting structure for connecting an output shaft of the motor;

furthermore, the connection mode of the shaft body and the two joints is conical surface connection.

Furthermore, two ends of the shaft body are provided with taper holes, and the axes of the taper holes are superposed with the axis of the shaft body; two the joints are provided with conical surfaces matched with the shaft body conical holes.

Further, the connection structure is a key groove, and the connection mode of the motor output shaft and the joint is key connection.

Further, the two joints are provided with bolts for further fastening the motor output shaft at the peripheries of the key grooves, the joints are provided with threaded holes matched with the bolts, and the positions of the threaded holes on the joints and the key grooves are in a diameter opposite situation with the joint centers so that the bolts can directly contact and press the motor output shaft.

The shaft body and the shaft body are made of carbon steel, so that the rotating shaft still has good toughness and strength during long-time continuous work, and adverse situations such as deformation and damage are avoided.

Since the technical scheme is used, the utility model discloses following beneficial effect has:

the utility model adopts the carbon steel as the material of the rotating shaft, improves the working reliability of the rotating shaft, avoids the situations of deformation, poor toughness and the like generated when the rotating shaft works continuously for a long time, and improves the production efficiency; the split design of the shaft body and the joint is adopted, so that the same butt joint can be suitable for shaft bodies with different lengths and different taper holes, the application range of the joint is widened, and the manufacturing cost of the joint is reduced; the conical surface connection of the joint and the shaft body has the functions of self-centering and torque transmission, and the connection structure is simple and reliable and has strong functionality; the bolt is used as a pressing part for further pressing the output shaft of the motor, and the pre-tightening stress can be adjusted by screwing the bolt, so that the operation is simple and the adaptability is strong.

Additional advantages, objects, and features of the invention will be set forth in part in the description which follows and in part will become apparent to those having ordinary skill in the art upon examination of the following or may be learned from practice of the invention. The objectives and other advantages of the invention may be realized and attained by the means of the instrumentalities and/or combinations particularly pointed out in the appended claims.

Drawings

The drawings of the present invention are described below.

FIG. 1 is a schematic structural view of example 1, and FIG. 2 is a schematic structural view of a joint of example 1; FIG. 3 is a schematic diagram of embodiment 2.

Detailed Description

The present invention will be further explained with reference to the drawings and examples.

Example 1

As shown in fig. 1-2, the unreeling rotating shaft provided in this embodiment includes a shaft body 1, two end surfaces of the shaft body 1 are respectively connected to a joint 2, and the shaft body 1 and the two joints 2 are detachably connected;

one end of each of the two joints 2, which is far away from the shaft body 1, is provided with a connecting structure for connecting an output shaft of a motor;

in this embodiment, the connection mode between the shaft body 1 and the two joints 2 is conical surface connection.

Two ends of the shaft body 1 are provided with taper holes, and the axes of the taper holes are superposed with the axis of the shaft body 1; two joints 2 are provided with conical surfaces matched with the conical holes of the shaft body 1.

In this embodiment, the connection structure on the joint is a key groove, and the connection mode of the motor output shaft and the joint 2 is a key connection, specifically, a flat key connection.

Two connect 2 the periphery of keyway be equipped with the bolt 3 that is used for further fastening motor output shaft, connect 2 and be equipped with the screw hole that cooperatees with bolt 3, the position on connecting 2 of screw hole is the relative situation of diameter with the keyway with connecting 2 centers to bolt 3 can direct contact, push down motor output shaft, and the effort of bolt and key is on a straight line, ensures that the bolt can not exert eccentric force to motor output shaft, increases the centering precision of device, improves the ride comfort.

The shaft body 1 and the shaft body 1 are made of carbon steel, so that the rotating shaft still has good toughness and strength during long-time continuous work, and adverse situations such as deformation and damage are avoided.

When the television set shaft is in work, the joints 2 at the two ends of the shaft body center and compress the shaft body 1 through the conical surfaces, and then the joints 2 are connected with the output shaft of the television set. The motor drives the shaft body 1 to rotate through the joint 2.

Example 2

This example differs from example 1 in that: the shaft body 1 and the joint 2 are connected by a bolt connection, as shown in fig. 3.

Finally, it is noted that the above embodiments are only used for illustrating the technical solutions of the present invention and not for limiting, and although the present invention has been described in detail with reference to the preferred embodiments, it should be understood by those skilled in the art that the technical solutions of the present invention can be modified or replaced by equivalents without departing from the spirit and scope of the technical solutions, which should be covered by the protection scope of the present invention.
