[0002] The quilting and embroidery machine is the main production equipment for quilting and embroidery of multi-layer fabrics such as clothing and bedding. The movement of the needle bar of the machine head is one of the two main movements of the quilting and embroidery machine to complete the pattern embroidery. At present, whether it is a quilting and embroidery machine, or a single quilting machine or embroidery machine, the up and down movement of the needle bar is driven by the same driving cam as the thread taking movement of the thread take-up lever.

[0004] The above-mentioned spring is single, and with continuous squeezing and resetting, the resetting elasticity becomes worse, which will also affect the frequency of quilting. In addition, no protective measures are taken for the spring, which causes the spring to rub for a long time, which easily causes the friction point to become thinner. Therefore, the force is uneven during squeezing and it is unable to provide a stable resetting problem. For this reason, we propose a multi-head double-row quilting and embroidery all-in-one machine.

The sleeve c603 has an active cavity 606, the outer wall of the rod b602 is connected to the plug b601, the outer wall of the rod a501 is movably connected to the spring a506, the inside of the rod a501 is movably connected to the piston 507, and the bottom of the piston 507 is movably connected to the piston 507. The part is connected to the disc 511 through a round rod 509, and the outer wall of the round rod 509 is movably connected to the limit spring 510. Side holes 508 are opened on both sides of the interior of the rod a501. The interior of the rod b602 includes a liquid storage chamber 608, a liquid inlet 609, an extrusion block 604, and a telescopic opening 610. The liquid storage chamber 608 is opened at the bottom of the rod b602, and the liquid inlet 609 is opened at the top of the liquid storage chamber 608. The extrusion block 604 is fixedly installed at the bottom of the rod b602, and the telescopic opening 610 is opened inside the extrusion block 604.

[0023] In this embodiment, by arranging the sleeve b6 and the sleeve a5, multiple springs a506 and spring b607 can be subjected to force during extrusion, so that the extrusion force is uniform, so that the reset speed will not be affected, and the use efficiency can be improved.

[0024] Specifically, the spring a506 and the rod a501 are both located inside the inner cavity 504, and the size of the disk 511 and the inner cavity 504 are adapted to each other.

[0025] In this embodiment, by providing an inner cavity 504, the spring a506 can be ensured to remain inside the sleeve rod a503 during the upward movement, and the bottom can allow the disc 511 to be squeezed with it, thereby facilitating subsequent resetting and use.

[0026] Specifically, the outer wall of the extension rod 605 and the interior of the telescopic opening 610 are adapted to each other, and the top of the extension rod 605 extends to the interior of the liquid storage cavity 608 .

[0027] In this embodiment, during operation, the extension rod 605 will extend into the interior of the card plug b601, which allows the lubricating liquid to adhere to the outer wall of the extension rod 605. When the extension rod 605 is pulled out and reset by the spring b607, the lubricating liquid will adhere to the outer wall of the spring b607, thereby playing a lubricating role and extending its service life.

[0028] Specifically, a connection port is provided at the top of the sleeve rod a503, the interior of the connection port and the outer wall of the rod a501 are sleeved together, and the disc 511 is twice the size of the connection port.

[0029] In this embodiment, the connecting port is provided so that the rod a501 can be freely extended and contracted, and the disc 511 is set to be twice the size of the connecting port so that the disc 511 will not fall out during the activity.

[0030] Working principle,

[0031] Step 1: Take out the card plug a502 and the card plug b601, and then inject lubricating liquid into the inside of the rod a501 and the rod b602. After the injection is completed, the card plug b601 and the card plug a502 are carded inside.

[0032] Step 2, during the working process, the needle rod 4 moves upward, causing the rod a501 fixedly connected to the outer wall of the sleeve a5 to extend from the inside of the sleeve rod a503, and the spring a506 will be retained in the inner cavity 504 during the movement, until the disc 511 extends from the bottom of the inner cavity 504 to the top of the inner cavity 504, which causes the disc 511 to squeeze the spring a506 on the outer wall, and when the spring a506 is squeezed, a rebound force will be formed to pull 14 back to its original position, and in the process of squeezing the spring a506, the disc 511 causes the piston 507 to extend from the inside of the rod a501, and the extended piston 507 will squeeze the limit spring 510, and when the spring a506 moves to the bottom of the rod a501, the seal of the side hole 508 is cancelled, which causes the lubricating fluid to extend from the inside of the side hole 508, which causes the outer wall of the spring a506 to contact with the lubricating fluid, thereby reducing the loss of the instrument and protecting the spring a506.

[0033] Step three, when the needle rod 4 moves downward, the rod b602 fixedly connected to the outer wall of the sleeve b6 will extend toward the inside of the sleeve c603. When extending, the extrusion block 604 will squeeze the spring b607 along the extension rod 605. When squeezed, it can be reset by the spring b607. When the extension rod 605 extends toward the inside of the rod b602, the lubricating liquid will adhere to the outer wall of the extension rod 605. When the extension rod 605 is pulled out and reset by the spring b607, the lubricating liquid will adhere to the outer wall of the spring b607, thereby playing a lubricating role and extending its service life.

[0034] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
