Abstract

The invention discloses a doubling cutting device which comprises a cutting mechanism with a cutter capable of moving up and down and a limit box arranged in front of a cutter according to the conveying direction of doubling, the limit box is provided with a limit channel for the doubling to pass through, and the top surface of the limit channel tilts downwards from the inlet end of the doubling to the outlet end of the doubling. When the cutter is used for cutting the doubling, the doubling is continuously conveyed forwards to realize an automatic buffering process, and further the jumping phenomenon is avoided, so that the production safety is higher, and the cutting quality of the doubling is also ensured.

Description

A kind of doubling cutting means

Technical field

The present invention relates to a kind of doubling cutting means, be specifically related to doubling before cutting the improvement of the position-limited box that must pass through

Background technology

Data wire or the transmission line that is used for transfer of data, image or transmission of sound signals to some commonly used in the electronic devices such as LCD or computer.Common this data wire or transmission line etc. are not a single plain conductor; It is the wire harness that is formed by the mutual adhesion of connecting line that much thinner peripheries are coated with insulating barrier; Generally be many connecting lines to be sticky side by side process flat flat cable, be called for short doubling.When doubling is made, be to forward, make doubling, finally make the doubling finished product successively through postprocessing working procedures such as gluing, curing, cooling, cutting and connecting terminals through connecting gear.

are as illustrated in fig. 1 and 2, and the doubling cutting means generally includes cutting mechanism (1 '), cutting mechanism (1 ') have can be up and down cutting knife (10 ').Doubling is sent to cutting mechanism (1 ') below by connecting gear, after cutting, gets into next process.To cut the position accurate in order to make, and the doubling cutting means also comprises a position-limited box (2 ') that is arranged on cutting knife (10 ') the place ahead of cutting mechanism (1 '), the straight limit channels that the inner formation of position-limited box (2 ') can supply doubling to pass through.Sometimes, when needs cut many doublings simultaneously, position-limited box (2 ') can also play the effect of concentrating doubling, causes doubling to cut malposition, uneven in length in order to avoid wire rod is at random.

Referring to Fig. 3, in the prior art, when cutting knife (10 ') falls when doubling cut; Brief stay can be arranged in doubling; The connecting gear that transmits doubling then can continue to be fed forward doubling, and this is easy to cause that the output of doubling has some setbacks, and produces the phenomenon of wire jumper or twisted wire; Cause cut bad, when serious even can cause shutdown

Summary of the invention

technical problem to be solved by this invention is to overcome phenomenons such as being easy to generate wire jumper or twisted wire when doubling cuts in the prior art and cause cutting bad problem, and a kind of improved doubling cutting means is provided.

For solving above technical problem, the present invention takes following technical scheme:

a kind of doubling cutting means; Comprise cutting mechanism with cutting knife that can be up and down; Be arranged on the position-limited box in said cutting knife the place ahead by the direction of transfer of doubling; Said position-limited box has the limit channels that can supply doubling to pass through, and according to the present invention, the end face of said limit channels is downward-sloping towards the port of export of doubling from the entrance point of doubling.

preferably, said position-limited box comprises the cuboid box body of both ends open, is provided with one in the said box body from the swash plate of doubling entrance point to the downward-sloping extension of the doubling port of export.

are preferably gone back the edge and are provided with the vertical dividing plate of polylith with the perpendicular direction horizontal Tile of the transmission direction of doubling in the said position-limited box.If there are many doublings to cut simultaneously, dividing plate can be separated many doublings and avoid twisted wire.

preferably, the vertical plane at the whereabouts track place when said cutting knife cuts downwards overlaps with the end face of the doubling port of export of position-limited box.

Because the enforcement of above technical scheme, the present invention compared with prior art has following advantage:

doubling cutting means of the present invention is arranged to from the doubling entrance point end face of the limit channels of position-limited box towards doubling port of export inclined downward; The wire jumper phenomenon that can effectively avoid doubling in the process of cutting, to occur easily; Make production security higher, also guaranteed the quality that cuts of doubling simultaneously.

Embodiment

are done further detailed explanation below in conjunction with concrete embodiment to the present invention, but are not limited to these embodiment.

Embodiment 1

referring to Fig. 4 ~ 7, the doubling cutting means of present embodiment comprises the cutting mechanism 1 with cutting knife 10 that can be up and down, is arranged on the position-limited box 2 in cutting knife 10 the place aheads by the direction of transfer of doubling; Position-limited box 2 comprises the cuboid box body of both ends open; And in box body, be provided with one from the swash plate 20 of doubling entrance point to the downward-sloping extension of the doubling port of export; Constituted the limit channels that can supply doubling to pass through between the bottom of swash plate 20 and box body, sidewall; Obviously, the end face of this limit channels also is downward-sloping towards the port of export of doubling from the entrance point of doubling.

this limit channels makes cutting knife when doubling is cut, and doubling continues to have forwarded an automatic buffering course, and is unlikely to produce the wire jumper phenomenon.

structure of the position-limited box of present embodiment certainly are an embodiment of the present invention; Other position-limited box structure; As long as can make the limit channels that constitutes in the position-limited box have the end face of the inclination the same with present embodiment; Can realize the object of the invention, thereby all should be in protection scope of the present invention.

In present embodiment, go back the edge in the position-limited box 2 and be provided with the vertical dividing plate of polylith 21 with the perpendicular direction horizontal Tile of the transmission direction of doubling.When many doublings were cut simultaneously, dividing plate 21 can be separated many doublings, and this also can effectively be avoided twisted wire.

in addition; The vertical plane at the track place, whereabouts during cutting knife 10 cutting downwards overlaps with the end face of the doubling port of export of position-limited box 2; Perhaps position-limited box 2 at least should be very near from the cut surface of cutting knife 2; Make doubling when going out position-limited box 2, can be cut, this also can bring into play the effect of position-limited box 2 the biglyyest, and can make doubling cut more concordantly.

More than the present invention has been done detailed description; Its purpose is to let the personage that is familiar with this art can understand content of the present invention and implements; Can not limit protection scope of the present invention with this; All equivalences of doing according to spirit of the present invention change or modify, and all should be encompassed in protection scope of the present invention
