Technical Field
The utility model relates to a feeding mechanism, concretely relates to novel four thick material needle pay-off flush joint machines's feeding mechanism of needle.
Background
The feeding modes of the sewing machine are various; such as: lower feeding (feed by feed dog); needle feeding (feeding a machine needle and a feed dog together); the comprehensive feeding (the needle, the inner presser foot and the outer presser foot are fed together with the feed dog) and the like meet the requirements of sewing materials with different materials and different thicknesses respectively. In practice, however, special effects often need to be sewn out. For example, two hemp ropes need to be sewn into two layers of hemp cloth, and because the material belongs to a medium-thick material, a flat sewing machine adopting a comprehensive feeding mode must be used, but because of special effects required by sewing, the effect cannot be achieved by adopting the comprehensive feeding mode, but the effect can be achieved by adopting a feeding mode of needle feeding, and the flat sewing machine adopting the needle feeding is also suitable for sewing thin materials, so that the difficult problem is difficult to solve.
Referring to fig. 1 and 2, a feeding mechanism of a conventional four-needle thick material comprehensive feeding flat sewing machine comprises a needle rod swing frame 1 for swinging feeding, a processing hole is formed in the needle rod swing frame 1, a needle rod 2 penetrates through the needle rod, a needle clamp 3 is connected to the needle rod 2, the needle clamp 3 is connected with four machine needles 4, an inner pressing rod 8 also penetrates through another processing hole of the needle rod swing frame 1, the lower end of the inner pressing rod 8 is connected with an inner presser foot 7, an outer pressing rod 9 is connected with a presser foot mounting rack 10, and the presser foot mounting rack 10 is connected with two outer presser feet 11. In the actual sewing process, the needle bar 2 and the inner pressing rod 8 are simultaneously penetrated in the needle bar swing frame 1, when the inner pressing foot 7 and the outer pressing foot 11 are both pressed on a needle plate 5, the needle bar swing frame 1 starts to swing, the needle 4, the inner pressing foot 7 and a cloth feeding tooth 6 synchronously feed materials, and the outer pressing foot 11 is jacked up when the inner pressing foot 7 feeds the materials and is pressed down after the inner pressing foot 7 feeds the materials, so that the alternating up-and-down movement with the inner pressing foot 7 is formed, and the feeding system of the whole thick material comprehensive feeding flat sewing machine is completed.

Detailed Description
In order to make the technical means, creation features, achievement purposes and functions of the present invention easy to understand and understand, the present invention is further explained by combining with the specific drawings.
Referring to fig. 3 and 4, the feeding mechanism of the novel four-needle thick material needle feeding lockstitch sewing machine provided by the present invention comprises a needle rod swing frame 100 and an outer pressing rod 200.
The needle bar swing frame 100 is provided with two mounting holes, one of which is provided with the needle bar 110, and the other of which is provided with the internal compression rod 120.
A needle holder 111 is connected to the needle bar 110, and four needles 112 are connected to the needle holder 111.
The structure is changed to be convenient for switching, and the bottom end of the inner compression rod 120 is provided with a mounting end which is used for being matched and connected with the inner compression pin.
One end of the outer pressing rod 200 is connected to an outer pressing foot mounting bracket 210, and an outer pressing foot 220 is connected to the outer pressing foot mounting bracket 210.
For demountable installation between outer presser foot 220 and the outer presser foot mounting bracket 210, specifically can be equipped with a plurality of screw on the outer presser foot mounting bracket 210, and be equipped with a plurality of on the outer presser foot 220 and correspond the complex through-hole with the screw, just so can realize dismantling between outer presser foot 220 and the outer presser foot mounting bracket 210 and be connected through the screw.
The outer presser foot 220 is used for corresponding matching with four needles 112, specifically, four strip-shaped through grooves 221 are arranged on the outer presser foot 220, each through groove 221 is corresponding matched with one needle 112, and the front and back positions of the needles 112 in the strip-shaped through grooves 221 can be adjusted.
Through the implementation of the structure, in the actual sewing process, the needle bar 110 penetrates through the needle bar swinging frame 100, when the needle bar swinging frame 100 swings, the needle 112 and the feed dog 300 of the sewing machine synchronously feed, and because the inner pressing foot is not arranged below the inner pressing rod 120, the outer pressing foot 220 always presses on the needle plate 400 of the sewing machine during working to do no feeding action, so that a mode of feeding the needle and the feed dog together is formed, and the feeding system of the whole thick needle feeding flat sewing machine is completed.
The following is a specific working principle of the present application:
when the needle bar swing frame 100 swings, the needle bar 110 inserted thereinside starts swinging, the needle holder 111 starts swinging by the swinging of the needle bar 110, and the four needles 112 also reciprocate together, completing the feeding operation in synchronization with the feed dog 300. After the outer presser bar 200 is pressed down, the presser foot mounting frame 210 is also pressed down together, so that the outer presser foot 220 is also pressed on the needle plate 400, because the inner presser bar 120 is not provided with the original inner presser foot, the inner presser foot and the outer presser foot do not interact, the working state of the outer presser foot 220 is always the pressing state, only the needle 112 and the feed dog 300 are used for synchronous feeding, but in order to enlarge the pressing range of the outer presser foot 220, the needle 112 needs to pass through the outer presser foot 220 for working, and because the needle 112 does reciprocating swing, the long strip-shaped through groove 221 on the outer presser foot 220 needs to be opened to avoid the dry movement with the needle 112, and the feeding action is not hindered. This just provides the assurance for the change of original four needle thick material integrated feeding lockstitch machine to novel four needle thick material needle feeding lockstitch machine, and if need change back original pay-off mode, only need change outer presser foot 220, installs original interior presser foot and just can accomplish the pay-off mode conversion, just also easily solves the problem through the presser foot interchange.
The basic principles and the main features of the invention and the advantages of the invention have been shown and described above. It will be understood by those skilled in the art that the present invention is not limited to the above embodiments, and that the foregoing embodiments and descriptions are provided only to illustrate the principles of the present invention without departing from the spirit and scope of the present invention. The scope of the invention is defined by the appended claims and equivalents thereof.
