Preferably, the adjusting device further comprises a limiting device which is arranged on the mounting plate and corresponds to the needle.

Preferably, the limiting device comprises limiting plates symmetrically connected to two sides of the lower end of the mounting plate, compression springs connected to the lower ends of the side walls of the two limiting plates opposite to each other, and limiting blocks connected to the other ends of the compression springs and abutted against the side walls of the syringe needles.

Preferably, one side of the limiting block close to the needle head is of a semi-arc structure.

Compared with the prior art, the beneficial effects of the utility model are that: when quilting cotton quilt, through the ball groove of spheroid and lead screw lower extreme, when syringe needle and cotton quilt have had the needle and thread rigid contact, the syringe needle just can the moving direction, avoids rigid contact automatically, prevents the syringe needle fracture, and on the other hand guarantees that quilting needle and existing needle and thread can not intersect, causes the texture to be pleasing to the eye, and the syringe needle moves the in-process up, under limiting plate, stopper and compression spring's combined action, and the syringe needle resumes original position, guarantees the yield, has very strong practicality.

Drawings

FIG. 1 is a schematic structural view of the present invention;

fig. 2 is an enlarged schematic view of part a of the present invention.

In the figure: the quilting machine comprises a workbench 1, a lifting device 2, a quilting machine frame 3, a slide rail 4, a linear motor 5, a turbine screw rod lifter 6, a screw rod 61, a ball body 62, a needle 63, a limiting plate 64, a limiting block 65 and a compression spring 66.

Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

Referring to fig. 1-2, the present invention provides a technical solution:

a full-automatic multi-needle computer quilter comprises a workbench 1, a quilting machine frame 3, lifting devices 2 positioned at the lower ends of two sides of the quilting machine frame 3, a slide rail 4 positioned below a cross bar of the quilting machine frame 3, a linear motor 5 installed on the slide rail 4, and a turbine screw rod lifter 6 installed at the lower end of the linear motor 5, wherein the lifting devices 2 are hydraulic lifting and contracting rods and are used for adjusting the position of the quilting machine frame 3, a computer controller is installed at one side of the quilting machine frame 3 and is used for controlling the displacement of a needle 63, a screw rod 61 is installed at the output end of the turbine screw rod lifter 6, and an adjusting device capable of changing the position of the needle 63 is installed at the lower end of the screw rod 61 and is used for preventing the needle 63 from breaking.

The adjusting device comprises a mounting plate and a ball body 62, wherein the lower end of the mounting plate is provided with a plurality of ball grooves and is connected to the lower end of the screw rod 61, the ball body 62 is inserted into the ball grooves at the lower end of the mounting plate, and the lower end of the ball body 62 is fixedly connected with the needle 63.
