Abstract

The utility model discloses a kind of full-automatic Sewing machines anti-chiseling down device, it comprises presser feet, presser feet drive plate, compression spring, cylinder, Pneumatic pressure hand and lifting screw, presser feet drive plate upper end is connected with the presser bar that can be arranged on up or down on head, lower end is connected with described presser feet, compression spring is sleeved on presser bar and this compression spring is arranged between head and presser feet drive plate, cylinder is fixed in head side, this cylinder piston rod by connecting plate and described Pneumatic pressure hand affixed, promoting screw level is arranged on connecting plate, presser feet drive plate is formed with one near the lower end, side of connecting plate can hold the breach promoting screw, driven by control cylinder and promote screw and then drive presser feet drive plate to move up and down.When sewing, by cylinder, presser feet is given, now presser feet pushes down cloth by compression spring, thus ensures in the process of sewing, and sewing cloth keeps impaction state always.Thus ensure not bore suede.

Description

Full-automatic Sewing machines anti-chiseling down device
Technical field
The utility model relates to a kind of full-automatic Sewing machines, especially a kind of full-automatic Sewing machines anti-chiseling down device.
Background technology
Because manual flat seam machine needs manual operations, require higher to the technical merit of operative employee, labour intensity is large, and production efficiency and yield rate are not high.Therefore full-automatic Sewing machines has started alternative manual flat seam machine and has been widely used.The presser feet of full-automatic Sewing machines is all adopt the eccentric wheel by connecting main shaft to drive presser feet reciprocating motion, i.e. presser feet reciprocating motion along with the reciprocating motion of shank when sewing.The technique of sewing eider down cut-parts is divided into two kinds of modes, and the first is exactly the lines and then go to fill suede of first sewing, and the second is exactly first fill suede and then go sewing.Full-automatic Sewing machines carry out the second technique sewing time, sewing thread can adopt cotton thread, but due to cotton thread surface roughness higher, and eider down cut-parts sew time do not carry out compressing thus cause sewing process in bore suede.Therefore, a kind of device can avoiding boring suede when this sewing is needed.
Summary of the invention
The technical problems to be solved in the utility model is to provide a kind of full-automatic Sewing machines anti-chiseling down device effectively can avoiding boring suede.
In order to solve the problems of the technologies described above, the utility model comprises presser feet, presser feet drive plate, compression spring, cylinder, Pneumatic pressure hand and lifting screw, described presser feet drive plate upper end is connected with the presser bar that can be arranged on up or down on head, lower end is connected with described presser feet, described compression spring is sleeved on presser bar and this compression spring is arranged between head and presser feet drive plate, described cylinder is fixed in head side, this cylinder piston rod by connecting plate and described Pneumatic pressure hand affixed, described lifting screw level is arranged on connecting plate, described presser feet drive plate is formed with one near the lower end, side of connecting plate can hold the breach promoting screw, driven by control cylinder and promote screw and then drive presser feet drive plate to move up and down.
Described Pneumatic pressure hand is arranged on the below of presser feet and sewing needle, and this Pneumatic pressure is formed with the pin hole passed for sewing needle on hand.
The upper surface of described Pneumatic pressure hand and lower surface are plane and the area of upper surface is greater than the area of lower surface, rounding off between the upper and lower surface of this Pneumatic pressure hand.
The beneficial effects of the utility model are: when sewing, by cylinder, presser feet is given, now presser feet pushes down cloth by compression spring, thus ensure in the process of sewing, and sewing cloth keeps impaction state always.Thus ensure not bore suede.

Fig. 2 is the schematic front view of the utility model full-automatic Sewing machines anti-chiseling down device.
Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail:
See Fig. 1 and Fig. 2, full-automatic Sewing machines anti-chiseling down device of the present utility model comprises presser feet 2, presser feet drive plate 3, compression spring 4, cylinder 5, Pneumatic pressure hand 6 and lifting screw 7, described presser feet drive plate 3 upper end is connected with the presser bar that can be arranged on up or down on head 1, lower end is connected with described presser feet 2, described compression spring 4 is sleeved on presser bar and this compression spring 4 is arranged between head 1 and presser feet drive plate 3, described cylinder 5 is fixed in head 1 side, this cylinder 5 piston rod by connecting plate and described Pneumatic pressure hand 6 affixed, described lifting screw 7 level is arranged on connecting plate, described presser feet drive plate 3 is formed with one near the lower end, side of connecting plate can hold the breach promoting screw 7, driven by control cylinder 5 and promote screw 7 and then drive presser feet drive plate 3 to move up and down.
Described Pneumatic pressure hand 6 is arranged on the below of presser feet 2 and sewing needle, and this Pneumatic pressure hand 6 is formed with the pin hole passed for sewing needle.
The upper surface of described Pneumatic pressure hand 6 and lower surface are plane and the area of upper surface is greater than the area of lower surface, rounding off between the upper and lower surface of this Pneumatic pressure hand 6.The structural design of rounding off can avoid Pneumatic pressure hand 6 to scratch cloth, so that makes troubles to processing.
When sewing, by cylinder 5, presser feet 2 is given, now presser feet 2 pushes down cloth by compression spring 4, thus ensures in the process of sewing, and sewing cloth keeps impaction state always.Thus ensure not bore suede.
In sum, content of the present utility model is not limited in the above-described embodiment, and those skilled in the art can propose other embodiment within technological guidance's thought of the present utility model, but these embodiments are all included within scope of the present utility model.
