Abstract

The invention discloses a thread take-off device of an embroidery awn cutter, which comprises an awn cutter frame, a level thread take-off roll which is arranged on the top of the frame, a plurality of bush-hooks which are arranged on the level thread take-off roll, two inclined thread take-off rolls which are positioned under the level thread take-off roll, a plurality of bush-hooks which are arranged on the inclined thread take-off roll, a dynamic drive device which is driven and connected with the level thread take-off roll and the inclined thread take-off roll, wherein two inclined thread take-off rolls and are matched with the level thread take-off roll to use on the frame in order to cut the thread when the angle between the embroidery and the radius thread is more than 45 degrees or less than 45 degrees, thereby the thread take-off device solves the difficulty that the traditional thread take-off device of the awn cutter can't cut the thread when the angle between the embroidery and the radius thread is less than 45 degrees, avoids artificial operation and improves the thread cut efficiency and the product quality.

Description

The thread hooking apparatus of embroidery shearing machine

Technical field

The present invention relates to a kind of embroidery shearing machine equipment, specifically, relate to a kind of thread hooking apparatus that carries out the embroidery shearing machine of trimming at various lines on the embroidery cloth.

Background technology

Traditional embroidery product all is to be main by artificial trimming head, workman's workload is big, effect is low, trimming is of poor quality, require operator's spirit high concentration during trimming, careless slightly can the leakage cut, cut unclean etc., at present, the manufacturer that has adopts shearing machine that embroidery is carried out trimming, its structure is the hook line roller that a level is installed on frame, on the hook line roller several billhooks are installed, in the embroidery rotating process, billhook is cut off the line on the embroidery with the rotation of hook line roller, has improved trimming efficient, reduced working strength of workers, but in use, because being horizontally disposed with of hook line roller, can only carrying out hook with the radial line direction greater than the line of 45 ° of angles to some and break, because the arrangement of the line on the embroidery, direction has nothing in common with each other, therefore the cutting facility of this shearing machine just can't carry out hook to some and the line of the little 45 ° of angles of radial line direction and breaks, and can only cut off by craft at present for such line, influence the trimming efficient and the product quality of embroidery.

Summary of the invention

The problem to be solved in the present invention provides the thread hooking apparatus of the embroidery shearing machine of a kind of trimming efficient that can improve embroidery and product quality.

For addressing the above problem, the technical solution used in the present invention is:

The thread hooking apparatus of embroidery shearing machine, comprise the shearing machine frame, it is characterized in that: the top of described frame is provided with horizontal hook line roller, on the described horizontal hook line roller several billhooks are installed, the below of described horizontal hook line roller is provided with two inclination hook line rollers, on the described inclination hook line roller several billhooks are installed, described horizontal hook line roller, inclination hook line roller are in transmission connection with Power Drive Unit respectively.

Below be the further improvement of the present invention to above technical scheme:

The lower horizontal of described frame is provided with crossbeam, and an end of described inclination hook line roller is connected with the crossbeam rotational support, and the angle between inclination hook line roller and the crossbeam is 10 °～60 °.

Described billhook comprises knife rest, on the described knife rest blade is installed, and the end of described knife rest has crooked knife rest head.

Described Power Drive Unit comprises motor, is respectively equipped with turning cylinder in described horizontal hook line roller, the inclination hook line roller, and described turning cylinder and motor are in transmission connection respectively.

Beneficial effect

The present invention adopts technique scheme, two inclination hook line rollers and horizontal hook line roller are set on frame to be used, both can be with disconnected greater than the line hook of 45 on the embroidery with the radial line angle, also can be with disconnected less than the line hook of 45 on the embroidery with the radial line angle, solved traditional shearing machine thread hooking apparatus can't with on the embroidery with the radial line angle less than the disconnected difficult problem of the line hook of 45, avoid manually-operated, improved trimming efficient and product quality.

Below in conjunction with the drawings and specific embodiments the technical program is described further:

Description of drawings
