Abstract

The invention discloses a dancing roll. The dancing roll comprises a center roll and roll seats arranged at the two ends of the center roll, wherein a first stopping cylinder and a pressing cylinder are fixed to the periphery of the center roll, the center roll is sleeved with a plurality of cylindrical aluminum alloy rollers, the cylindrical aluminum alloy rollers are arranged between the first stopping cylinder and the pressing cylinder, and are arranged in the axial direction of the center roll, the cylindrical aluminum alloy rollers are connected with the center roll through bearings corresponding to the cylindrical aluminum alloy rollers respectively, the first stopping cylinder abuts against an external end bearing arranged on one side of the first stopping cylinder on the center roll, the pressing cylinder is fixedly connected with the cylindrical aluminum alloy roller which is adjacent to the pressing cylinder, the end, close to the cylindrical aluminum alloy roller, of the pressing cylinder is attached to the center roll through a bearing bush, the end, far away from the cylindrical aluminum alloy roller, of the pressing cylinder is connected with the center roll through the external end bearing, the external end bearing is limited through a second stopping cylinder, and the first stopping cylinder and the second stopping cylinder are fixed to the periphery of the center roll. According to the dancing roll, a paper tape can be conveniently pulled, and the paper tape is prevented from breakage when being pulled.

Description

Dancing roll

Technical field

The present invention relates to dancing roll.

Background technology

At present conventional dancing roll, because self roller is heavy very large, can hinder the traction of paper tape, can allow paper tape distract fractured when serious.

Summary of the invention

The object of the present invention is to provide a kind of dancing roll, the traction that it can facilitate paper tape, prevents paper tape distract fractured.

For achieving the above object, technical scheme of the present invention is a kind of dancing roll of design, comprises breast roll and the roller seat that is positioned at center shaft two ends;

Described breast roll periphery is fixed the first stop bit cylinder and clamping cylinder;

Described breast roll overlaps between the first stop bit cylinder and clamping cylinder some aluminum alloy round cylindrical drum along breast roll axial array;

Described rotatingcylindrical drum is connected with breast roll by each self-corresponding bearing;

Described the first stop bit cylinder props up the outer side bearing that is positioned at the first stop bit cylinder one side on breast roll;

Described clamping cylinder and the rotatingcylindrical drum being adjacent are fixed, described clamping cylinder reclines by bearing shell and breast roll near one end of this rotatingcylindrical drum, described clamping cylinder is connected with breast roll by side bearing away from one end of this rotatingcylindrical drum, and described side bearing is spacing by the second stop bit cylinder;

Described the first stop bit cylinder, the second stop bit cylinder are fixed on breast roll periphery.

Preferably, described the first stop bit cylinder stretches in the rotatingcylindrical drum being adjacent.

Preferably, described clamping cylinder stretches in its adjacent rotatingcylindrical drum.

Advantage of the present invention and beneficial effect are: a kind of dancing roll is provided, and the traction that it can facilitate paper tape, prevents paper tape distract fractured.

By single dancing roll being changed into the form of a plurality of aluminum alloy round cylindrical drum, by a plurality of aluminum alloy round cylindrical drum, being contacted respectively with paper tape, because aluminum alloy round cylindrical drum self is low weight, and is sectional type, paper tape traction can be very smooth and easy, paper tape distract fractured can not occur.

Accompanying drawing explanation

Fig. 1 is schematic diagram of the present invention.

The specific embodiment

Below in conjunction with drawings and Examples, the specific embodiment of the present invention is further described.Following examples are only for technical scheme of the present invention is more clearly described, and can not limit the scope of the invention with this.

The concrete technical scheme of implementing of the present invention is:

As shown in Figure 1, a kind of dancing roll, comprises breast roll 1 and the roller seat 2 that is positioned at center shaft two ends;

Described breast roll 1 periphery is fixed the first stop bit cylinder 3 and clamping cylinder 4;

Described breast roll 1 has some aluminum alloy round cylindrical drum 5 along breast roll 1 axial array at the first stop bit cylinder 3 and 4 covers of clamping cylinder;

Described rotatingcylindrical drum 5 is connected with breast roll 1 by each self-corresponding bearing 6;

Described the first stop bit cylinder 3 props up the outer side bearing 7 that is positioned at the first stop bit cylinder 3 one sides on breast roll 1;

Described clamping cylinder 4 and the rotatingcylindrical drum 8 being adjacent are fixing, described clamping cylinder 4 reclines by bearing shell and breast roll 1 near one end of this rotatingcylindrical drum 8, described clamping cylinder 4 is connected with breast roll 1 by side bearing 9 away from one end of this rotatingcylindrical drum 8, and described side bearing 9 is spacing by the second stop bit cylinder 10;

Described the first stop bit cylinder 3, the second stop bit cylinder 10 are fixed on breast roll 1 periphery.

Described the first stop bit cylinder 3 stretches in the rotatingcylindrical drum 5 being adjacent.

Described clamping cylinder 4 stretches in its adjacent rotatingcylindrical drum 5.

 

The above is only the preferred embodiment of the present invention; it should be pointed out that for those skilled in the art, do not departing under the prerequisite of the technology of the present invention principle; can also make some improvements and modifications, these improvements and modifications also should be considered as protection scope of the present invention.
