Description

A kind of flexible jig

Technical field

It the utility model is related to roll web production equipment technology, and in particular to one kind is applied on roll paper dividing and cutting machine Flexible jig.

Background technology

Roll web is widely used as sanitary paper, and the production process of roll web is：The volume of strip is produced in advance Coil paper, the roll web of strip is then cut into some sections, then each section of roll web is packed.

When cutting into some sections, it is necessary to there is the fixture for fixing the roll web of strip.And existing conventional brace, As shown in figure 1, its structure includes the relatively-stationary left side 1 ' in position and right side 2 ', both are in the arc plate of symmetric design Shape structure, by the roll web sandwiched of strip wherein.

Conventional brace has certain limitation：First, it does not have power drive, fully relies on and manually adjusts fixture, raw Produce less efficient, labour's intensity is big；Secondly, left side can not be movable and mobile, and after right side can only be extruded by product It is passive, small range is adaptively movable, the applicability that this allows for fixture is poor, when the roll web production of production different-diameter size , it is necessary to be changed and reinstalled to a whole set of fixture, calibrated during product, this has had a strong impact on production efficiency, and improves life Produce cost.

In the prior art, such as authorized announcement date disclosed for the Chinese patent CN103042554B of on 02 04th, 2015 A kind of roll paper dividing and cutting machine, wherein just including the interval paper advance mechanism includes to be slidingly arranged in frame along vertical equity Slide, transverse horizontal be arranged on slide be used for place the hopper of roll web, transverse horizontal is arranged between being used on slide Having a rest property promotes the belt pusher that the roll web in hopper moves forward, and the hopper is by the affixed side that is arranged on slide Plate and mobile side board surround, and the mobile side board is included positioned at the transportation section of the saw blade side and positioned at the saw blade opposite side Deferent segment, connection is provided with the slide and drives the mobile side board transportation section to be relatively fixed side plate movement with conveying The first cylinder and connection for clamping roll web drive the mobile side board deferent segment to be relatively fixed side plate movement with when cutting Compress the second cylinder of roll web；It is provided with the slide on the pressing plate above hopper deferent segment and connection driving pressing plate 3rd cylinder of lower movement.

Wherein, hopper is surrounded by the fixed side and mobile side board being arranged on slide, and mobile side board transportation section can be by The driving of one cylinder is relatively fixed side plate movement, clamps roll web in conveying, can prevent from running out of when roll web is being pushed ahead Hopper, mobile side board deferent segment can be driven by the second cylinder and be relatively fixed side plate movement, compressed roll web when cutting, can prevent Roll web beat when cutting causes otch out-of-flatness, the 3rd cylinder can roll web it is last all when drive pressing plate to be pressed from top Tight roll web, prevent because of the shorter beat when cutting of roll web or drop.

The technical scheme is additionally arranged three different cylinders of effect, produced on the basis of existing fixture as shown in Figure 1 When Anti-fall when respectively reaching pusher, clamp roll web and the purpose of anti-beat cut when roll web is shorter when cutting.But The technical scheme can not still meet the problem of equipment applicability is poor, can not produce the product of multiple sizes, and flexibility is low, simultaneously Overall complex in structure, equipment operating procedure is more in production, and production cost is higher.

Utility model content
