Abstract

The utility model relates to a preservative film cutting device, comprising a sliding rail and a cutting knife seat hiding a cutting edge. The cutting knife seat is arranged on the sliding rail along which the cutting knife seat can slide. The surface of the sliding rail corresponding to the cutting knife seat coats an adsorbed layer made of high molecular material for the adsorption of a preservative film. Therefore, the utility model can raise the convenient performance of cutting the preservative film.

Description

Preservative film cutting device

Technical field

The utility model relates to a kind of preservative film cutting device, is meant a kind of preservative film cutting device through surfaction especially, can flatten a preservative film fast, and then improves the convenience that uses.

Background technology

As shown in Figure 1, the preservative film cutting device of generally commonly using 1 includes a slide rail 2, and the cutting tool rest 3 being located at slide rail 2 and can sliding relatively, wherein, slide rail 2 is located at the outside of a preservative film box body A, therefore, the user can pull out the preservative film B in the box body A earlier, and preservative film B is smooth on slide rail 2, promote cutting tool rest 3 again, cut preservative film B with cutting tool rest 3 built-in blade (not shown) simultaneously.

Yet,, make between preservative film B and slide rail 2 surfaces to have absorption affinity hardly because slide rail 2 surfaces are smooth smooth plane, therefore, in cutting preservative film B, preservative film B is easy to generate fold with extremely, and then the smoothness of obstruction cutting action, cause user's inconvenience.

Be head it off, common means are on the cutting tool rest a plurality of rollers to be installed, but this practice will increase the cost that the cutting tool rest is made assembling, and the gap between each roller and slide rail surface must be controlled at (because preservative film is quite thin) in certain scope, in case produce excessive gap, the effect that then flattens preservative film will be had a greatly reduced quality, and therefore need other better solution.

Summary of the invention

At the problems referred to above, main purpose of the present utility model is to provide a kind of preservative film cutting device, and it can effectively flatten preservative film fast, makes cutting action more smooth and easy, increases the convenience that uses.

Secondary objective of the present utility model is to provide a kind of preservative film cutting device, and it is simple in structure, can effectively reduce and make and assembly cost.

For achieving the above object, a kind of preservative film cutting device provided by the utility model, it includes a slide rail, an and cutting tool rest of being located at slide rail slidably, wherein, the cutting tool rest is built-in a blade, and slide rail then is coated with the adsorption layer of a macromolecular material corresponding to the surface of cutting tool rest, is used to adsorb a preservative film.

Wherein, adsorption layer can be selected polyvinyl chloride (PVC), polyethylene (PE), polypropylene (PP), plastic of poly vinyl acetate (EVA), third butadiene styrene resin macromolecular materials such as (ABS) for use, because the material of adsorption layer is close with the preservative film material, therefore, when adsorption layer and preservative film are quite pressed close to, will produce absorption affinity between the two.

By this, the user can pull out a preservative film, and fit in the surface of adsorption layer easily, and can keep the smooth of preservative film by the absorption affinity between adsorption layer and preservative film, make preservative film be difficult for producing fold, with utilizing cutting tool rest cutting preservative film, process is quick and convenient, and moves smooth and easy and steady.

The specific embodiment

In order to describe structure of the present utility model and characteristics place in detail, preferred embodiment and conjunction with figs. below existing the act describe.

As shown in Figure 4, be a kind of preservative film cutting device 10 provided by the utility model, it is located at a preservative film box body 40 outsides, includes a slide rail 20, and a cutting tool rest 30 of being located at slide rail 20 slidably, wherein:

As Fig. 2, shown in Figure 3, slide rail 20 offers the chute 21 of an inverted T shape, then is provided with an adhesive sheet 22 with respect to a side of chute 21 openings, is used to be pasted on preservative film box body 40.In addition, the opening both side surface of chute 21 also uses the extrusion coated mode to be coated with the adsorption layer 23 of a macromolecular material (adopting polyvinylchloride in the present embodiment), is used to adsorb a preservative film 41.

Cutting tool rest 30 protrudes out the sliding part 31 of inverted T shape to embed chute 21 and can slide relatively, and sliding part 31 also along the major axis of chute 21 to being provided with a blade 32 with cutting preservative film 41, in addition, cutting tool rest 30 is concaved with the pushing and pressing part 33 of an arc with respect to an end of sliding part 31, is convenient to user's hand pushing and pressing cutting tool rest 30 that slides.

Thus, as shown in Figure 4, the utility model can utilize adhesive sheet 22 to be pasted on a side of preservative film box body 40, pull out the preservative film 41 in the box again, and preservative film 41 evened up adsorption layer 23 surfaces that fit in slide rail 20, simultaneously preservative film 41 will be adsorbed fixing, so the user easily slippage cutting tool rest 30 cut preservative films 41, process is convenient and quick, and preservative film 41 will keep its flatness and can guarantee that the smooth and easy of cutting action is with stable.

In sum, the utility model is a unique and novel design, the design of ingenious utilization adsorption layer and promote the smooth and easy and quality of preservative film cutting, and can not cause the significantly increase of cost of manufacture, can reach the purpose of this utility model really.

The above only is an embodiment of the present utility model, is not to be used for limiting scope of patent protection of the present utility model, thus the equivalence that all utilization the utility model specifications and claim content are done variation, all should be in scope of patent protection of the present utility model.
