Summary of the invention:
The purpose of this utility model be to provide a kind of compress dynamics evenly, cost, make the regularity of fabric dividing obtain significantly improving the cloth presser on layout machine.
The utility model is achieved in that
Cloth presser on layout machine, include two spaced matrixes, between two matrixes, be provided with compress axle and presser foot, on compress axle, be elasticly connected with compress bar, compress bar and compress axle be arranged in parallel, are provided with compress motor on the matrix of a side, and compress motor drives compress axle to rotate by drive unit, the action of compress motor is controlled by controller, between described compress axle and compress bar, by compress spring leaf elasticity, is connected.
Above-mentioned drive unit is: include the compress motor cam on the motor shaft that is arranged on compress motor, it is external and be installed with and dial bar that a side group is stretched out in one end of compress axle, dialling bar is connected by extension spring elasticity with compress motor cam, on a side of compress motor or matrix, be provided with the limit switch coordinating with compress motor cam, compress motor cam touches limit switch control compress motor and stops operating, compress electric machine rotation drives compress motor cam wheel to dial bar and then driving compress axle and compress bar and rotates the effect that reaches compress, compress motor stops operating, extension spring resets compress bar.
Between above-mentioned presser foot and matrix, by being connected flat tube, connect.
The baseplane of above-mentioned compress bar is provided with sponge.
The utility model compared to existing technology outstanding advantage is:
1, between compress bar of the present utility model and compress axle, by spring leaf elasticity, be connected, the uniformity when elasticity by spring leaf itself regulates compress bar compress, make compress dynamics with and uniformity be all improved, and make the regularity of fabric dividing obtain significantly improving;
2, the utility model has changed two electromagnet in original structure into a compress motor, has reduced production cost.
The specific embodiment:
With specific embodiment, the utility model is further described below, referring to Fig. 1-2:
Cloth presser on layout machine, include two spaced matrixes 1, take cutter arm as matrix 1, between two matrixes 1, be provided with compress axle 2 and presser foot 3, be elasticly connected with compress bar 4 on compress axle 2, compress bar 4 be arranged in parallel with compress axle 2, on the matrix 1 of a side, be provided with compress motor 5, compress motor 5 drives compress axle 2 to rotate by drive unit, and the action of compress motor 5 is controlled by controller, between described compress axle 2 and compress bar 4, by compress spring leaf 9 elasticity, is connected.
Above-mentioned drive unit is: include the compress motor cam 6 on the motor shaft that is arranged on compress motor 5, one end of compress axle 2 is stretched out outside a side group body 1 and is installed with and dials bar 7, dial bar 7 and dial bar for aluminium, dialling bar 7 is connected by extension spring 8 elasticity with compress motor cam 6, on group bar 7, be provided with screw, on compress motor cam 6, be provided with through hole, one end of extension spring hooks on screw, the other end hooks on through hole, on a side of compress motor 5 or matrix 1, be provided with the limit switch coordinating with compress motor cam 6, compress motor cam 6 touches limit switch control compress motor 5 and stops operating, compress motor 5 rotates and drives compress motor cam 6 effect group bars 7 and then driving compress axle 2 and compress bar 4 to rotate the effect that reaches compress, compress motor 5 stops operating, extension spring 8 resets compress bar 4.
Drive unit can also be: be arranged on pitch wheel on motor shaft and compress axle 2, on motor shaft, be installed with sensing chip, on sensing chip, be provided with two with compress axle 2 reset modes and compress state position blade one to one, on compress motor 5, be provided with the inductor of sensitive sheet, compress motor 5 rotates, by meshed gears, drive compress axle 2 and compress bar 4 to rotate the effect that reaches compress, sensing chip rotates with motor shaft, when inductor senses sensing chip, now compress bar 4 is in compress state, compress motor 5 stops operating, when compress bar 4 resets, drive motors rotates backward, when inductor senses sensing chip, compress bar 4 resets, compress motor 5 stops operating.
Between above-mentioned presser foot 3 and matrix 1, by being connected flat tube 10, connect.
The baseplane of above-mentioned compress bar 4 is provided with sponge.It is large that sponge is chosen frictional force, harder sponge.
The utility model carries out Qie Bu to after cloth presses signal cutting knife.
Operation principle of the present utility model is:
Two ends as matrix 1, form whole framework with connecting flat tube 10 by cutting knife wall, are connected the uniformity when elasticity by itself regulates compress bar 4 compress between compress axle 2 and compress bar 4 by compress spring leaf 9; During work when machine direction of travel is not when putting cloth state, compress motor 5 rotates counterclockwise, drive 6 rotations of compress motor cam to stir aluminium and dial bar 7, thereby make compress axle 2 rotate the effect that reaches compress, when compress motor cam 6 forwards the end to, touch limit switch and stop 5 rotations of compress motor, then reset by extension spring 8 compress bars.
Above-described embodiment is only one of preferred embodiment of the present utility model; not with this, limit practical range of the present utility model; therefore: all equivalences of doing according to shape of the present utility model, structure, principle change, within all should being covered by protection domain of the present utility model.
