Abstract

The utility model discloses a coating machine, which comprises a guide roller. The guide roller comprises an arch mandrel and a flexible cylindrical shaft sleeved outside the arch mandrel, and the arch mandrel and the flexible cylindrical shaft can rotate relative to each other. The guide roller of the coating machine is provided with the arch mandrel, the middle height of the guide roller can be adjusted by rotating the angle of the arch mandrel, tension difference among the middle and two ends of a base material can be adjusted, the base material can be flatted, and coating can be uniform.

Description

A kind of coating machine

Technical field

The utility model relates to adhesive tape production equipment field, particularly relates to a kind of coating machine.

Background technology

Coating machine is used for the coating production of adhesive tape, and the groundwork process is glue, coating or the printing ink etc. that the base material of rolling are coated with the last layer specific function, and oven dry back rolling.In the coating production process, if find base material thickness 0.035 when following, the tension force of the centre of base material is different with the tension force on both sides; Mid portion is prone to the phenomenon that arches upward and give a discount; These a lot of physical properties with base material are relevant, like processing technology of fracture strength, percentage elongation, base material etc., as also adopting original straight barrel type guide roller base material unreeled and rolling; After rolling can appear in the finished product of then being produced arch upward in the centre, the phenomenon that the glue of surface-coated, coating or printing ink crawling are even.

For avoid this because of base material too thin; Thereby intermediate tension is developed the low similar olivary guide roller in high two, a kind of centre less than the even phenomenon of crawling that both sides tension force occurs in the prior art, can increase the middle tension force of base material; Make base material smooth docile, coating evenly.But in a single day this guide roller shape is confirmed just can't adjust, and the tension force situation of base material is relevant with numerous factors, thereby the intermediate tension of each volume base material is all different with the difference of both sides tension force, even the situation of intermediate tension greater than both sides tension force can occur.Re-use this olive shape guide roller and only can play the effect of running counter to desire.

The utility model content

The technical problem that the utility model mainly solves provides a kind of coating machine, can make coating evenly according to base material situation adjustment guide roller shape.

For solving the problems of the technologies described above; The technical scheme that the utility model adopts is: a kind of coating machine is provided; Comprise guide roller, said guide roller comprises: the flexible sleeve axle that the arch mandrel is outer with being enclosed within said arch mandrel can relatively rotate between said arch mandrel and the said flexible sleeve axle.

In preferred embodiment of the utility model, the middle peak of said arch mandrel and two-end-point difference in height are 8～15mm.

In preferred embodiment of the utility model, said flexible sleeve axle is the tubular structure that rubber or plastic production form.

In preferred embodiment of the utility model, said coating machine comprises two or more guide rollers.

The beneficial effect of the utility model is: the coating machine of the utility model, its guide roller have an arch mandrel, through rotating the angle of arch mandrel; Can adjust the intermediate altitude of guide roller; Thereby the centre of adjustment base material and the Tension Difference at two ends make base material smooth, and then make coating evenly.

Description of drawings

Fig. 1 is the structural representation of a preferred embodiment of guide roller in the utility model coating machine;

Fig. 2 is the another kind of status architecture sketch map of Fig. 1;

The mark of each parts is following in the accompanying drawing: 1 is the arch mandrel, and 2 is the flexible sleeve axle, and 21 are tensioning face.

The specific embodiment

Below in conjunction with accompanying drawing the preferred embodiment of the utility model is set forth in detail, thereby the protection domain of the utility model is made more explicit defining so that advantage of the utility model and characteristic can be easier to it will be appreciated by those skilled in the art that.

See also Fig. 1, the utility model embodiment comprises:

A kind of coating machine comprises that this guide roller comprises: arch mandrel 1 and flexible sleeve axle 2 like the described guide roller of Fig. 1 (not mark); Flexible sleeve axle 2 is straight barrel type, is sleeved on outside the arch mandrel 1, process because of flexible sleeve axle 2 adopts the material of flexible deformables such as rubber, plastics, thereby the contacted one side of arcuate surface of flexible sleeve axle 2 and arch mandrel 1 can outwards arch upward; Flexible sleeve axle 2 can relatively rotate with arch mandrel 1; The tensioning face of guide roller 21 is arch, and contacts with base material.The middle peak of arch mandrel 1 and two-end-point difference in height are 8～15mm.

Shown in Figure 2 is the another kind of duty of guide roller, and arch mandrel 1 is rotated 180 °, with the contacted tensioning face 21 of base material be the plane.

Preferably, coating machine comprises two or more guide rollers.

The course of work of the utility model coating machine is following: with rolls on guide roller; Rotate arch mandrel 1 according to the centre of base material and the tension force situation at two ends; Thereby adjustment and contacted tensioning face 21 radians of base material; Make the smooth docile back of base material fixed arch core axle 1, begin the coating program then.Lead in the process of volume at base material, arch mandrel 1 is motionless, and flexible sleeve axle 2 can rotate under the effect of drive unit, thereby can drive advancing of base material.

The guide roller of the utility model coating machine through rotating the angle of arch mandrel, can be adjusted the intermediate altitude of guide roller, thereby the centre of adjustment base material and the Tension Difference at two ends make base material smooth, and then makes coating evenly.

The above is merely the embodiment of the utility model; Be not thus the restriction the utility model claim; Every equivalent structure or equivalent flow process conversion that utilizes the utility model specification and accompanying drawing content to be done; Or directly or indirectly be used in other relevant technical fields, all in like manner be included in the scope of patent protection of the utility model.

Claims
