Abstract

The utility model discloses a tension structure of a slitting machine, wherein a first support is arranged on one side of a tension mechanism, a first support is arranged on a cloth roll rack, two driving rollers are arranged on the tension mechanism, and tension rollers are arranged above the two driving rollers. The tension structure of the slitting machine can guarantee tension stability when cloths pass through, is not affected by the size of cloth rolls, enables wide cloths not easy to swing, and smoothly cuts to improve quality of slit products.

Description

A kind of tension structure of banding machine

Technical field

The utility model relates to a kind of banding machine, refers in particular to a kind of tension structure of banding machine.

Background technology

As shown in Figure 1, the disclosed split air conditioner of prior art, mainly by stretching device 10, slitting mechanism 20 and receiving mechanism (not shown), formed, stretching device 10 is for making cloth tensioning, slitting mechanism 20 cuts into wide cut coiled material the coiled material in a narrow margin of various applicable need of productions, receiving mechanism tightens up being suitable for producing coiled material in a narrow margin after shearing, yet, the tension force control of unreeling material and rolling material is that the tension force control of the key link that affects banding machine shearing quality, especially unreeling material directly affects shearing quality.

Two parallel drive rolls 101 are normally installed in prior art on stretching device 10, drive roll 101 is by the transmission of transmission device (not shown), then above two drive rolls 102, support 102 is set, cloth roll 103 is erected on support 102, need the cloth of itemize to be placed on the centre of two drive rolls 101, the tension force of cloth feeding relies on the friction force between two drive rolls 101 of cloth and bottom to control completely, when the coil diameter of cloth is larger, the own wt of cloth is also large, now friction force is also larger, it is relatively good that the tension force of feeding can regulate.

Yet, when cloth blowing is smaller to coil diameter, along with alleviating of own wt, and the friction force between two drive rolls 101 of bottom picking-up cloth reduces gradually, tension force is just uncontrollable, and in cutting process, wide cut cloth easily swings, make to cut unfairness, have a strong impact on itemize product design out.

Utility model content

The purpose of this utility model is to provide a kind of tension structure that improves the banding machine of shearing quality by increasing pressure.

For reaching above-mentioned purpose, solution of the present utility model is:

A tension structure for banding machine, arranges the first support in stretching device one side, and cloth roll is erected on the first support; Two drive rolls are set on stretching device, above two drive rolls, jockey pulley are set.

Further, two drive rolls be arranged in parallel, and the contact surface of jockey pulley and two drive rolls is tangent respectively.

Further, jockey pulley is erected at two drive roll tops by the second support in rotating mode.

Adopt after such scheme, the utility model cloth roll is by the first stent support, simultaneously, by jockey pulley by cloth presser on two drive rolls, because the weight of jockey pulley is fixed, therefore, can guarantee the tension stability that cloth passes through, and be not subject to the impact of cloth roll size, wide cut cloth be difficult for to be swung, cut smooth and improve itemize product design out.

Accompanying drawing explanation

Fig. 1 is prior art banding machine tension structure schematic diagram;

Fig. 2 is the utility model structural representation.

Label declaration

Stretching device 10 drive rolls 101

Support 102 cloth roll 103

Stretching device 1 first support 11

Drive roll 12 second supports 13

Slitting mechanism 2 cloth roll 3

Jockey pulley 4.

The specific embodiment

Below in conjunction with drawings and the specific embodiments, the utility model is described further.

Consult shown in Fig. 2, the tension structure of a kind of banding machine that the utility model discloses, is mainly comprised of stretching device 1, slitting mechanism 2 and receiving mechanism (not shown).

In stretching device 1 one sides, the first support 11 is set, cloth roll 3 is erected on the first support 11, and cloth roll 3 can be rotated around the first support 11.Two drive rolls 12 are set on stretching device 1, above two drive rolls 12, jockey pulley 4 are set.

For further increasing the friction drag of cloth, two drive rolls 12 be arranged in parallel, and the contact surface of jockey pulley 4 and two drive rolls 12 is tangent respectively.

Jockey pulley 4 is erected at two drive roll 12 tops by the second support 13 in rotating mode, and jockey pulley 4 is pressed on cloth all the time.

When the utility model is used, cloth roll 3 is erected on the first support 11, and cloth is laid on two drive rolls 12, is sheared, and tightened up by receiving mechanism through slitting mechanism 2 by it; Jockey pulley 4 by cloth presser on two drive rolls 12, thereby the stability of tension force while guaranteeing that cloth is sheared, and then improve shear after the quality of product.

The foregoing is only an embodiment of the present utility model, the not restriction to this case design, all equivalent variations of doing according to the design key of this case, all fall into the protection domain of this case.

Claims

1. a tension structure for banding machine, is characterized in that: in stretching device one side, the first support is set, cloth roll is erected on the first support; Two drive rolls are set on stretching device, above two drive rolls, jockey pulley are set.

2. the tension structure of a kind of banding machine as claimed in claim 1, is characterized in that: two drive rolls be arranged in parallel, and the contact surface of jockey pulley and two drive rolls is tangent respectively.
