Abstract
The invention relates to a film cutting-off device, which comprises an installing plate and a coiling roller used for coiling a film, wherein a press roller pressed on the film of the coiling roller is arranged on the installing plate. The film cutting device is characterized in that a cutter swinging arm is hinged onto the installing plate, a cutter capable of cutting off the film is arranged on one end, near the coiling roller, of the cutter swinging arm, a pressing and brushing block capable of flattening the film onto the coiling roller when the film is cut off by the cutter is arranged on the cutter, and a driving mechanism driving the cutter swinging arm to rotate is arranged on the installing plate. The film cutting-off device has the advantages that the structure is simple, the film can be stably coiled after being cut off by the cutter, and cut tailings are fewer.
Description
[technical field]
The present invention relates to a kind of film cutting device.
[background technology]
Film, when rolling completes, needs film to cut off, then changes winding up roller and carry out rolling.Existing rolling-up mechanism, all there is some problem in the rolling structure as printer, dry compound machine etc.: the first, and the tailing that rolling splicing cutting knife cuts off is longer; The second, moment the suddenly disappearing due to memberane stress that the tailing of rolling is cutting off, tailing is easy to be crimped and collects, and for some specialities, may affect its rolling effect.
[summary of the invention]
The object of the invention is to overcome the deficiencies in the prior art, provide a kind of tailing few and film is cut off the film cutting device of rear steady rolling.
In order to solve the problem, the present invention by the following technical solutions:
A kind of film cutting device, comprise the winding up roller of adapter plate and volume film, described adapter plate is provided with the pressure roller be pressed on winding up roller film, it is characterized in that: described adapter plate is hinged with cutting knife swing arm, described cutting knife swing arm is provided with the cutting knife that can cut off film near one end of described winding up roller, described cutting knife is provided with and film flattening can be pressed in pressure brush block on winding up roller when cutting knife cuts off film, and described adapter plate is provided with the driver train that the cutting knife swing arm described in driving is rotated.
A kind of film cutting device as above, it is characterized in that: described cutting knife swing arm is provided with the cutting knife transmission gear that cutting knife swing arm can be driven to rotate around hinge, described driver train comprises the driving cylinder be fixed on described adapter plate, described driving cylinder cylinder axis one end is provided with and is hinged on described adapter plate and can cylinder is driven to promote the transmission swing arm of rotating, and described transmission swing arm is provided with the swing arm tooth engaged with described cutting knife transmission gear.
Beneficial effect of the present invention has: when cutting knife cuts off film, pressure brush block can push down tailing immediately, can pulsation-free rolling on winding up roller, so just, the tailing crimping of rolling can not be caused because film cuts off the unexpected disappearance of rear film tension force, and in order to press brush block can be pressed on winding up roller after cutting knife cuts off film, cutting knife must as much as possible near winding up roller, and the tailing cut off like this is shorter.
[accompanying drawing explanation]
Schematic front view when Fig. 1 is cut-out film of the present invention;
Schematic front view when Fig. 2 is non-blank of the present invention.
[detailed description of the invention]
Below in conjunction with accompanying drawing and detailed description of the invention, the present invention is described in further detail:
As illustrated in fig. 1 and 2, a kind of film cutting device, comprise the winding up roller 2 of adapter plate 1 and volume film, adapter plate 1 is provided with the pressure roller 3 be pressed on winding up roller 2 film, adapter plate 1 is hinged with cutting knife swing arm 4, cutting knife swing arm 4 is provided with the cutting knife 5 that can cut off film near one end of winding up roller 2, the blade of cutting knife 5 is downward, and cutting knife 5 needs as much as possible near winding up roller 2.Cutting knife 5 is provided with when cutting knife 5 cuts off film, film flattening can be pressed in the pressure brush block 6 on winding up roller 2, pressure brush block 6 is located at cutting knife 5 on the end wall of winding up roller 2, when cutting off film, immediately film tailing can be pressed to winding up roller 2, thus the tailing of cut-out is smoothed rolling, guarantee that tailing is smooth, and do not affect tailing use, reach the loss-free object of rolling.Adapter plate 1 is provided with the driver train 7 driving cutting knife swing arm 4 to rotate.Cutting knife swing arm 4 is provided with the cutting knife transmission gear 41 that cutting knife swing arm 4 can be driven to rotate around hinge, driver train 7 comprises the driving cylinder 71 be fixed on adapter plate 1, drive cylinder 71 cylinder axis one end to be provided with and be hinged on adapter plate 1 and can cylinder 71 driven to promote the transmission swing arm 72 of rotating, transmission swing arm 72 can be cam, cylinder axis is connected to one end of cam lobe, and transmission swing arm 72 is provided with the swing arm tooth 73 engaged with cutting knife transmission gear 41.When driving cylinder 71 to stretch, can promote transmission swing arm 72 and rotate around hinge, the swing arm tooth 73 in transmission swing arm 72 is with moving knife transmission gear 41, and cutting knife swing arm 4 is rotated around hinge, thus drives cutting knife 5 to carry out blank.Have in diagram and connected by slewing arrangement by two windings up roller 2, two winding up roller, after a roller rolling is complete, rotates and change another roller.
