Abstract
The invention discloses a full automatic sewing machine velvet anti-drilling apparatus, which comprises a presser foot, a presser foot driving plate, a pressure spring, an air cylinder, a pneumatic presser hand and a lift bolt, wherein an upper end of the presser foot driving plate is fixedly connected to a presser foot bar mounted on a machine head with vertical movement and a lower end thereof is fixedly connected to the presser foot; the presser spring sleeves the presser foot bar and the presser spring is set between the machine head and the presser foot driving plate; the air cylinder is fixedly connected at one side of the machine head; the piston rod of the air cylinder is connected to the pneumatic presser hand through a connecting plate; the lift bolt is horizontally mounted on the connecting plate; a notch capable of containing the lift bolt is formed on a lower end at one side of the presser foot driving plate close to the connecting plate; and air cylinder is controlled to drive the lift bolt and further the lift bolt is driven to drive the presser foot driving plate to move vertically. When sewing, the presser foot is put down through the air cylinder; and at this time, a piece of cloth is pressed by the presser foot through the presser spring, thus the sewed cloth is ensured to be in the press state during the sewing process; and further velvet is ensured not to be drilled.
Description
Technical field
The present invention 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 problem to be solved in the present invention 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 present invention includes 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 invention has the beneficial effects as follows: when sewing, by cylinder, presser feet is given, now presser feet pushes down cloth by compression spring, thus ensure in the process of sewing, sewing cloth keeps impaction state always.Thus ensure not bore suede.
Accompanying drawing explanation
Fig. 1 is the perspective view of the present invention's full-automatic Sewing machines anti-chiseling down device;
Fig. 2 is the schematic front view of the present invention's full-automatic Sewing machines anti-chiseling down device.
Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the present invention is further detailed explanation:
See Fig. 1 and Fig. 2, full-automatic Sewing machines anti-chiseling down device of the present invention 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 invention 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 invention, but these embodiments all comprise within the scope of the present invention.
