First clamping jaw and the second clamping jaw, first clamping jaw of finger cylinder are fixedly connected with upper needle plate, open up on the upper needle plate and wear pawl
Hole, second clamping jaw of finger cylinder is passed through in pawl hole and is fixedly connected with lower needle plate from wearing for upper needle plate, described to wear in pawl hole
With for avoiding the mobile avoiding space of the second clamping jaw.
Further, multipair sliding block is provided in the clamping jaw fixed plate, each pair of sliding block is fixedly installed respectively and in clamping jaw
Fixed plate two sides, each pair of sliding block arrange that the inner side of slider offers upper hopper chute under respectively along clamping jaw fixed plate length direction
Sliding slot, upper and lower needle plate are located between each pair of sliding block, and the upper needle plate two sides are located in the upper hopper chute of two side slides, institute
Lower needle plate two sides are stated to be located in the gliding groove of two side slides.
Further, the upper row's needle being arranged below the upper needle plate is two rows, the lower row's needle being arranged below the lower needle plate
For two rows.
The beneficial effects of the present invention are:
The present invention provides a kind of cloth gripping mechanism, the crawl to cloth may be implemented, and grasping stability is reliable every time.
The cloth gripping mechanism moves back and forth after being inserted into cloth by upper and lower row's needle, design on fabric surface is made to generate tension,
It realizes the crawl of cloth, takes cloth process reliable and stable, and cloth can be made to be removed in the state of keeping smooth, it is ensured that take
The quality of cloth.

Specific embodiment
Presently in connection with attached drawing, the present invention is further illustrated.These attached drawings are simplified schematic diagram only with signal side
Formula illustrates basic structure of the invention, therefore it only shows the composition relevant to the invention.
As shown in Figure 1 to Figure 3, a kind of cloth gripping mechanism, including upper needle plate 2 and lower needle plate 3 are provided, upper needle plate 2 is under
Needle plate 3 is arranged in parallel and spacing up and down, and upper needle plate 2 and lower needle plate 3 do along needle plate length direction and move in parallel relatively.
There are two upper row's needles 21 for upper 2 lower end surface of needle plate setting, and there are two lower row's needle 31, upper rows for lower 3 lower end surface of needle plate setting
The quantity of needle 21 and lower row's needle 31 determines that target cloth area is larger, can be corresponding according to the practical cloth size to be taken
The quantity of needle 21 and lower row's needle 31 is arranged in increase.Multiple pin holes passed through for upper row's needle 21, pin hole tool are offered on lower needle plate 3
Have for avoiding the mobile avoiding space of upper row's needle 21, the needle point of upper row's needle 21 and lower row's needle 31 is in the same plane.
Parallel moving mechanism between above-mentioned upper needle plate 2 and lower needle plate 3 are as follows:
Finger cylinder 4 is installed, for finger cylinder 4 towards needle plate, finger cylinder 4 includes the first clamping jaw in clamping jaw fixed plate 1
With the second clamping jaw, the first clamping jaw of finger cylinder 4 is fixedly connected with upper needle plate 2, is opened up on upper needle plate 2 and is worn pawl hole, finger cylinder 4
The second clamping jaw pass through in pawl hole and be fixedly connected with lower needle plate 3 from wearing for upper needle plate 2, wear in pawl hole have for avoid second
The mobile avoiding space of clamping jaw.
To ensure movement stable in parallel between upper and lower needle plate, therefore, three pairs of sliding blocks 5 are provided in clamping jaw fixed plate 1, often
Sliding block 5 is fixedly installed respectively in 1 two sides of clamping jaw fixed plate, each pair of sliding block 5 is arranged along 1 length direction of clamping jaw fixed plate, sliding
5 inside of block offers upper hopper chute and gliding groove respectively, and upper and lower needle plate is located between each pair of sliding block 5, upper 2 two sides of needle plate difference
In the upper hopper chute of two side slides 5, lower 3 two sides of needle plate are located in the gliding groove of two side slides 5.
In actual operation, the needle point of upper row's needle 21 and lower row's needle 33 in cloth gripping mechanism is pierced into the cloth of lower section simultaneously
In material, then 4 operation of finger cylinder, finger cylinder 4 drives upper needle plate 2 and lower needle plate 3 to be displaced outwardly, and makes row's needle 21 under
Design on fabric surface is generated tension by row's needle 31, is caught cloth by the needle point in upper row's needle 21 and lower row's needle 31 insertion cloth, is formed
Grasp realizes the crawl to cloth.
Cloth gripping mechanism of the invention, maximum feature be, captured in quilting industry cloth is inconvenient to grab,
The problem of cloth stability difference is taken, and grabs the smooth corrugationless of process, takes cloth quality high.
Taking the above-mentioned ideal embodiment according to the present invention as inspiration, through the above description, relevant staff is complete
Various changes and amendments can be carried out without departing from the scope of the technological thought of the present invention' entirely.The technology of this invention
Property range is not limited to the contents of the specification, it is necessary to which the technical scope thereof is determined according to the scope of the claim.
