A kind ofly enter clamp device for film transverse drawing mill
Technical field
The present invention relates to a kind of film transverse drawing mill, specifically, relate to and a kind ofly enter clamp device for film transverse drawing mill, belong to cellulose membrane technical field.
Background technology
Transverse drawing mill is a kind of device film being carried out to cross directional stretch, form primarily of guide rail and chain folder, guide rail is are pivotably for no reason, the each guide rail in both sides, chain is installed on guide rail can free-open-close flexibly, synchronous operation under driven by motor, guide rail broadens, gradually to realize the cross directional stretch to sheet material simultaneously.In the operational process of equipment, entering folder is a very important link.Current drawing machine is mainly used in the higher material of the deflections such as PET, enter to clamp to be equipped with shearing roller, lifting tray etc., but this deflection of the picture cellulose membrane material that high humility is not larger again, soft due to it, traditional folder mode that enters very easily causes its distortion wrinkling, causes and cannot enter folder.
Summary of the invention
The problem to be solved in the present invention is for above deficiency, there is provided a kind of and enter clamp device for film transverse drawing mill, overcome in prior art the defect entering clamp device, adopt of the present invention enter clamp device, have structure simple, easy to operate, enter to press from both sides the advantage that efficiency is high, security is high.
For overcoming the above problems, the technical solution adopted in the present invention is: a kind ofly enter clamp device for film transverse drawing mill, it is characterized in that, comprises pallet.
A kind of prioritization scheme, pallet is hollow sealing casing, and its surface is provided with several pores.
Further, the shape of pallet is front wide and rear narrow.
Further, pore is uniformly distributed and size is identical.
Further, the both sides of pallet are respectively equipped with compressed-air atomizer.
Further, pallet, compressed-air atomizer are communicated with compressed air piping respectively.
Further, upper deflector roll, the lower guide roll that cellulose membrane can be compressed after also comprising cooperation.
Further, pallet is arranged on lower guide roll side.
Further, enter clamp device to coordinate with drawing machine.
Further, the drawing machine clamp mouth part that clamp device is arranged on drawing machine is entered.
The present invention adopts above technical scheme, compared with prior art, has the following advantages:
1, because there is the carrying of pallet, solve cellulose membrane because of conduct oneself with dignity sagging cause cannot go up folder, operation is very easy.
2, adopt the mode of air cushion, cellulose membrane no longer contact with tray surface, reduces friction force during cellulose membrane operation, and it is very high to enter to press from both sides efficiency, and empirical tests, reaches 100%; And traditional pallet must contact with cellulose membrane, under the impact of friction force, cellulose membrane distortion is wrinkling, causes folder difficulty.
Cellulose membrane is fixed by the pressure 3, in utilization between deflector roll, lower guide roll, cellulose membrane is played and supports effect that is fixing and guiding, both cellulose membrane can have been prevented sagging because conducting oneself with dignity, can prevent again air-flow from being blown afloat by cellulose membrane, play an important role to the even running of cellulose membrane, the equipment of ensure that can long-time continuous run.
Cellulose membrane limit is blown in jaws by the air-flow 4, utilizing compressed-air atomizer to eject, and meet accident when avoiding manual operation is pressed from both sides injury, substantially increases the security into folder operation.
Below in conjunction with drawings and Examples, the invention will be further described.
Description of the invention provides in order to example with for the purpose of describing, and is not exhaustively or limit the invention to disclosed form.Many modifications and variations are obvious for the ordinary skill in the art.Selecting and describing embodiment is in order to principle of the present invention and practical application are better described, and enables those of ordinary skill in the art understand the present invention thus design the various embodiments with various amendment being suitable for special-purpose.

Embodiment
Embodiment 1, as Fig. 1, Fig. 2, Fig. 3, shown in Fig. 4, a kind ofly enter clamp device for film transverse drawing mill, comprise foundation plate 1, pallet 3, foundation plate 1 has guide roller support 2, guide roller support 2 is provided with two upper deflector rolls 4 that cellulose membrane can be compressed after coordinating, lower guide roll 9, upper deflector roll 4, bearing 7 is respectively equipped with between lower guide roll 9 and its rotating shaft, one end of upper deflector roll 4 is hinged by bearing pin 5 and guide roller support 2, the other end of upper deflector roll 4 is provided with handle 6, pallet 3 is arranged on lower guide roll 9 side, be fixed on foundation plate 1 by tray supporter 8, the both sides of pallet 3 are respectively equipped with compressed-air atomizer 11, pallet 3 is front wide and rear narrow hollow sealing casing, pallet 3, compressed-air atomizer 11 respectively with tensimeter 10, compressed air piping 12 is communicated with, the surface uniform of pallet 3 is distributed with the identical pore of several sizes 14, enter clamp device to coordinate with drawing machine 15, be arranged on drawing machine jaws 13 place of drawing machine 15.
Concrete use operation is as follows: by pallet 3, lower guide roll 9 and drawing machine jaws 13 adjust to sustained height, before using, pressurized air valve is opened, pressurized air is passed in pallet 3, controlling opening of valve controls air inflow, tensimeter 10 expression is counted to and reaches predetermined value, pressurized air is discharged by the pore of pallet 3 surface uniform distribution, one deck air cushion is formed on pallet 3 surface, upper deflector roll 4 one end is forced in by handle 6, upper deflector roll 4 other end rotates around bearing pin 5, now moist cellulose film is passed between upper lower guide roll, upper deflector roll 4 relies on self gravitation by moist cellulose film compacting on lower guide roll 9, the thickness that air inflow changes air cushion is controlled by control valve, prevent moist cellulose film and pallet 3 surface contact, the resistance that increased fiber element film advances, two deflector rolls simultaneously play support and fixation to cellulose membrane, both cellulose membrane can have been prevented sagging because conducting oneself with dignity, can prevent again air-flow from being blown afloat by cellulose membrane.
Now opening installation is at the switch of the compressed-air atomizer 11 of pallet 3 both sides, air-flow is utilized to blow in drawing machine jaws 13 by cellulose membrane limit, during drawing machine running, drawing machine jaws 13 is closed, film limit is clamped, under the traction of drawing machine, cellulose membrane completes clip process through this device, enters folder rate and reaches 100%.
