Description

Carving knife

Technical field

The utility model relates to die-cutting machine technical field, particularly relates to a kind of carving knife in circular pressing and cutting machine.

Background technology

The viscous layer that die cutting product generally comprises one deck release liners, protective layer and is positioned between the two.Die cutting product is widely used in automobile making, electron trade, especially in flat-panel screens, mobile digital industry.According to the shape of electronic product inner frame, the die-cutting rule punching press of given shape or roll mode cross cutting is utilized to go out specific shape.Then the protective layer of overburden removing, is covered in die cutting product on the inner frame of electronic product, then peels release liners, is finally utilized by the shell of electronic product the viscosity of viscous layer to firmly fix inner frame and the shell of electronic product.

The die-cutting rule of circular pressing and cutting machine and the working portion of bed are cylindrical shape, and are cut by die cutting product by the extruding of die-cutting rule and bed.Die-cutting rule of the prior art comprises roll shaft and the some dise knifes be fixedly installed.As time goes on, can there is certain wearing and tearing even breach in dise knife, thus cause the barycenter of dise knife to offset, and then cause shaking of whole carving knife.If but occur that dise knife wearing and tearing or breach just change dise knife, then can increase the manufacturing cost of enterprise.

In view of this, be necessary to be improved the carving knife in circular pressing and cutting machine of the prior art, to solve the problem.

Utility model content

The purpose of this utility model is open a kind of carving knife, prevents the dise knife in carving knife from causing centroid motion and causing beating of dise knife because of wearing and tearing or breach, and reduces enterprise and change the cost of dise knife.

For realizing above-mentioned utility model object, the utility model discloses a kind of carving knife, comprising base, be vertically set on the riser on base plate, the phase of described riser arranges bearing to the inside, connects the roll shaft of bearing, described roll shaft arranges some dise knifes, and dise knife is by sleeve fixing dise knife

The side of described sleeve is provided with some annular recess, accommodates balancing weight in described annular recess.

As further improvement of the utility model, described annular recess uniform intervals centered by the central through hole of sleeve distributes and runs through described sleeve.

As further improvement of the utility model, described roll shaft is provided with external screw thread, and the sidewall of the central through hole of described sleeve has internal thread, and sleeve moves along the direction extending longitudinally of roll shaft by the external screw thread of roll shaft.

As further improvement of the utility model, between described sleeve and dise knife, be also provided with buffers packet covering layer.

As further improvement of the utility model, described buffers packet covering layer is the rubber of annular.

Compared with prior art, the beneficial effects of the utility model are: in the utility model, do not offset by the barycenter putting into balancing weight to guarantee the dise knife that wearing and tearing or breach occur in annular recess, prevent rocking of whole carving knife, reduce the cost that enterprise changes dise knife.

Detailed description of the invention

Below in conjunction with each embodiment shown in the drawings, the utility model is described in detail.

A kind of detailed description of the invention of the utility model carving knife shown in please refer to the drawing 1 to Fig. 4.

As shown in Figures 1 and 2, in the present embodiment, this carving knife 100, comprise base 50, be vertically set on the riser 10 on base plate, the phase of described riser arranges bearing 20 to the inside, connects the roll shaft 30 of bearing, described roll shaft 30 arranges some dise knifes 40, and dise knife 40 is by sleeve 401 fixing dise knife 40; Wherein, the side of this sleeve 401 is provided with some annular recess 411, accommodates balancing weight 412 in described annular recess 411.Buffers packet covering layer 402 is also provided with between sleeve 401 and dise knife 40; Concrete, this buffers packet covering layer 402 is the rubber of annular.In the present embodiment, the both sides of each dise knife 40 arrange the rubber of two-layer annular respectively, by the rubber of annular, significantly reduce the vibration of dise knife 40 during slitting operation, improve the quality of die cutting product.

Shown in ginseng Fig. 3, in the present embodiment, this annular recess 411 uniform intervals centered by the central through hole 413 of sleeve 401 distributes and runs through described sleeve 401.In the present embodiment; each sleeve 401 is symmetrical arranged four annular recess 411; certainly also the quantity of this annular recess 411 can be set to six or two, as long as guarantee that annular recess 411 uniform intervals centered by the central through hole 413 of sleeve 401 distributes.

Shown in reference Fig. 4, when carving knife 100 to employ after a period of time after wearing and tearing or breach occur dise knife 40, balancing weight (not shown) can be put into guarantee that the barycenter of certain dise knife 40 does not offset in this annular recess 411, prevent whole carving knife 100 from shaking.Specifically, the balancing weight putting into annular recess 411 can be the metal derby of back with gum, and by doing " dynamic balancing " to determine the concrete installation site of balancing weight to the dise knife 40 that wearing and tearing or breach occur.

Further, in the present embodiment, this roll shaft 30 is provided with external screw thread, and the sidewall of the central through hole 413 of described sleeve 401 has internal thread, and sleeve 401 moves along the direction extending longitudinally of roll shaft 30 by the external screw thread of roll shaft 30.

A series of detailed description listed is above only illustrating for feasibility embodiment of the present utility model; they are also not used to limit protection domain of the present utility model, all do not depart from the utility model skill equivalent implementations of doing of spirit or change all should be included within protection domain of the present utility model.

In addition, be to be understood that, although this description is described according to embodiment, but not each embodiment only comprises an independently technical scheme, this narrating mode of description is only for clarity sake, those skilled in the art should by description integrally, and the technical scheme in each embodiment also through appropriately combined, can form other embodiments that it will be appreciated by those skilled in the art that.
