Description

TECHNICAL FIELD

[0001] The utility model belongs to the technical field of the yarn cutting machine, and particularly relates to a non-damage yarn cutting machine. BACKGROUND

[0002] In order to guarantee the beauty of life clothes, song and dance or opera costumes, tablecloths, pillowcases, cushions and other daily necessities and screens, wall hangings and other furnishings, embroidery is often used to leave patterns or characters on the surface, and a yarn cutting machine is needed to cut the hanging line at the bottom of the embroidery pattern during the embroidery process.

[0003] At present, the existing yarn cutting machine blade design has defects, and there is a gap between the blade edge of the pick and the support seat. During work, the yarn that should be cut on the blade is easily stuck in the gap and cannot contact the blade edge, and is pulled off during the pick stage of the yarn cutting machine, resulting in the pattern appearing to be locked and scattered.

[0004] Therefore, in view of the above-mentioned problems of the existing yarn cutting machine blade design, the gap between the blade edge of the pick and the support seat, and the yarn being easily pulled off during work and not being cut, resulting in the pattern appearing to be locked and scattered, a non-damage yarn cutting machine is designed to improve the pick, so that all the yarn can be cut by the sharp blade edge during the pick work. INVENTION CONTENTS

[0005] In order to overcome the problem of the existing yarn cutting machine pick support seat and blade gap, and the yarn being easily pulled off during work and resulting in the pattern appearing to be locked and scattered.

[0006] The technical scheme of the utility model is: a non-damage yarn cutting machine, comprising a support base, a support platform, a pick composed of a blade and a support seat, and a moving block; the support base is provided with a support platform with a through groove, the woven fabric is fixed in the through groove of the support platform, the pick is arranged below the woven fabric, the mounting seat is composed of an arc plate and a support block fixedly connected to the arc plate, the blade is installed in the support block and is in the same horizontal plane as the support block, the moving block is arranged below the support platform, and the pick is installed on the moving block.

[0007] Preferably, the gap between the blade and the support seat is removed, the yarn path of the pick is smooth, the yarn can smoothly reach the blade inlet, so that the yarn is easily cut, thereby greatly reducing the pressure of the lock needle being pulled apart, preventing the problem of the lock needle being scattered, the support platform fixes the woven fabric above the pick, the moving block drives the pick to move left and right, and the yarn is cut.

[0008] As a preferred embodiment, the support platform has equidistantly arranged first anchor holes. A fixing thread is inserted into the first anchor hole, passing through the fabric and forming a link. The fixing thread first passes through the fabric and then through the first anchor hole and is then sewn onto the fabric, fixing the fabric in the through groove opened on the support platform. The through groove design facilitates embroidery on the fabric surface by manual labor or embroidery machine.

[0009] Preferably, a threaded rod is inserted into the support base, and a limiting post is fixedly connected inside the support base above the threaded rod. Rotating the threaded rod can drive the moving block and the pick knife installed on the moving block to move.

[0012] Preferably, a groove is provided on the left side of the movable block, and an electric slider that matches the groove is slidably connected in the groove. The position of the pick knife mounted on the slider is changed by the electric slider sliding in the groove, so as to change the position of the pick knife according to the size of the fabric and make it easier to move the pick knife to a position with more hanging threads for cutting.

[0013] As a preferred option, a mounting base with a second anchor hole is fixedly connected to the right side of the pick blade. The mounting base is close to the left side of the electric slider, and a screw is screwed into the second anchor hole. The pick blade is fixed to the electric slider through the mounting base. This design allows the pick blade to be disassembled and installed, so as to maintain and replace the blade and avoid blade wear or rust that would cause cutting difficulties.

[0014] The beneficial effects of this utility model are:

[0015] By designing a non-destructive yarn cutting machine, the gap between the blade and the support is eliminated, making the yarn path of the cutting blade smooth and allowing the yarn to reach the blade inlet smoothly so that the yarn can be easily cut. All the yarn can be cut by the sharp blade, which greatly reduces the pressure of the locking needle being pulled apart and prevents the problem of locking needle detachment.

[0016] The pick-up knife moves back and forth at the bottom of the support platform via an electric slider, while the moving block drives the pick-up knife to move left and right, thereby changing the position of the pick-up knife according to the size of the fabric being woven.

[0023] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0024] Please see Figures 1-5 This utility model provides an embodiment: a non-destructive yarn cutting machine includes a support base 1, a support platform 2, a pick-up knife composed of a blade 3 and a support seat 4, and a moving block 5; the support base 1 is equipped with a support platform 2 with a through groove, the fabric is fixed in the through groove of the support platform 2, and a pick-up knife is arranged below the fabric; the mounting base 14 is composed of an arc plate and a support block fixedly connected to the arc plate; the blade 3 is installed in the support block and is at the same level as the support block; a moving block 5 is arranged below the support platform 2, and the pick-up knife is installed on the moving block 5; by eliminating the gap that originally existed between the blade 3 and the support seat 4, the yarn path of the pick-up knife is made smooth, and the yarn can smoothly reach the blade inlet so that the yarn can be easily cut, thereby greatly reducing the pressure of the locking needle being pulled apart and preventing the problem of locking needle detachment; the support platform 2 fixes the fabric above the pick-up knife, and the moving block 5 drives the pick-up knife to move left and right to cut the yarn.

[0025] In this embodiment, the support platform 2 has equidistantly arranged anchor holes 6. A fixing thread that passes through the fabric and forms a loop is inserted into the anchor hole 6. A threaded rod 7 is inserted into the support base 1. A limiting post 8 located above the threaded rod 7 is fixedly connected to the support base 1. The moving block 5 has a screw hole that matches the threaded rod 7 and a slot that matches the limiting post 8. The moving block 5 is screwed onto the threaded rod 7 and sleeved onto the limiting post 8. A drive motor 9 is installed on the left side of the support base 1. The transmission element of the drive motor 9 is connected to the left end of the threaded rod 7. The fixing thread first passes through the fabric, then through the anchor hole 6, and is then sewn onto the fabric to fix the fabric to the support platform. The through slot on the 2nd is designed to facilitate embroidery on the fabric surface by hand or embroidery machine. Rotating the threaded rod 7 can drive the moving block 5 and the pick knife installed on the moving block 5 to move. The threaded rod 7, the limiting post 8 and the pick knife are initially stopped at the edge of the support platform to prevent obstruction of the central embroidery area. Under the restriction of the limiting post 8, the moving platform screwed to the threaded rod 7 cannot rotate with the threaded rod 7, but moves left and right on the path planned by the limiting post 8. By moving to the left, the yarn at the bottom of the fabric is cut. The drive motor 9 provides power to the threaded rod 7, so that the moving block 5 drives the pick knife to move automatically to the left, so that the yarn slides to the right onto the blade 3 and is then cut by the blade 3.

[0026] In this embodiment, a groove 10 is provided on the left side of the moving block 5. An electric slider 11 that matches the groove 10 is slidably connected in the groove 10. A mounting base 14 with a second anchoring hole 13 is fixedly connected to the right side of the pick knife. The mounting base 14 is close to the left side of the electric slider 11. A screw is screwed into the second anchoring hole 13. The front and rear positions of the pick knife mounted on the electric slider 11 can be changed by sliding the electric slider 11 in the groove 10, so that the position of the pick knife can be changed according to the size of the fabric. This makes it easier to move the pick knife to a position with more hanging threads for cutting. The pick knife is fixed on the slider by the mounting base 14. This design allows the pick knife to be disassembled and installed, so that the blade 3 can be maintained and replaced, avoiding the difficulty of cutting caused by the wear or rust of the blade 3.

[0027] When working, the staff first place the fabric on the support platform 2, then sew the fixing thread through the first anchor hole 6 onto the fabric to fix it, and then embroider the pattern on the fabric by hand or embroidery machine.

[0028] After the embroidery is completed, the electric slider 11 is activated according to the position of the center of the fabric. The electric slider 11 moves in the slide groove 10 to drive the pick knife to move back and forth at the bottom of the support platform 2. The pick knife is moved to the area where the hanging thread is concentrated. The drive motor 9 is activated, and the drive motor 9 drives the threaded rod 7 to rotate. Under the restriction of the limit post 8, the pick knife is moved to the left. During the leftward movement of the pick knife, the hanging thread slides to the right and enters the blade 3 of the pick knife, where it is cut by the blade 3. After cutting, the drive motor 9 is activated again to move the pick knife back to the right side.

[0029] When the blade 3 of the pick is damaged after a period of use, remove the screws screwed into the second anchor hole 13, remove the pick fixed to the mounting base 14, and then take the blade 3 out of the support base 4 for replacement. After replacement, install the pick onto the electric slider 11.

[0030] Through the above steps, a non-destructive yarn cutting machine is designed to eliminate the gap that originally existed between the blade 3 and the support 4, making the yarn path of the picker blade smooth and allowing the yarn to smoothly reach the blade inlet so that the yarn can be easily cut. All the yarn can be cut by the sharp blade 3, thereby greatly reducing the pressure of the locking needle being pulled apart and preventing the locking needle from coming apart. This solves the problem that there is a gap between the picker blade support 4 and the blade 3 in the existing yarn cutting machine, which easily pulls the yarn apart during operation, causing the locking frame of the pattern to come apart.

[0031] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present invention.
