Description

Technical Field

[0001] The utility model relates to the field of embroidery machines, in particular to an embroidery machine head. Background Art

[0002] Embroidery machine, embroidery machine, or embroidery machinery. When embroidery first started to break away from hand embroidery, the so-called embroidery machine at that time was not a real embroidery machine, because the embroidery machine at that time was a traditional sewing machine with a base plate with small round holes, the sewing needle kept going in and out, and the cloth stretched by the hand-held embroidery frame moved back and forth. In fact, this so-called embroidery machine is still a kind of hand embroidery. The embroidery machine head is the core component of the embroidery machine, and the embroidery machine needle is installed on the head.

[0003] According to the published patent 202022016922.5, an embroidery machine head includes a head body, a slot is provided at the bottom of the head body, a movable column is inserted into the outside of the head body, and limiting columns are fixedly connected to both sides of the movable column. The movable column and the limiting column are movably connected to the head body, and a fixed plate is fixedly connected to the outer surface of the movable column. The advantages of the utility model are: when disassembling the embroidery needle, only two pulling blocks need to be pulled to move the limiting top column out of the limiting hole, so that the needle sleeve can be quickly taken out downward, and then the embroidery needle can be directly pulled out, which makes it easy to replace the embroidery needle; when the embroidery needle is working, the vibration is transmitted to the needle sleeve, and the hydraulic shock absorber between the needle sleeve and the machine head body can absorb and reduce the vibration. The shock absorbing plate is a manganese-copper alloy with excellent shock absorbing and damping effect, thereby greatly improving the shock absorbing effect of the embroidery machine head. In the process of realizing the utility model, the inventor found that at least the following problems in the prior art have not been solved: when disassembling the embroidery needle, only two pulling blocks need to be pulled to move the limiting top column out of the limiting hole, so that the needle sleeve can be quickly taken out downward After the needle sleeve is removed, the embroidery needle can be directly pulled out, which makes it easy to replace the embroidery needle. This solves the problem of wear of the embroidery needle due to long-term work, and the existing embroidery machine head is inconvenient to disassemble the needle sleeve of the embroidery needle, so it is inconvenient to disassemble and replace the embroidery. However, during use, the traditional embroidery machine head can only conveniently disassemble and assemble the embroidery needle. This disassembly and assembly method uses a limiting top column to limit the position of both sides of the embroidery needle, but the connection area between the limiting top column and the needle sleeve is low, and the pull block is movable through the spring pulling method. There is a situation where the pull block shakes and moves during use, and the needle sleeve and the embroidery needle shake and move together, resulting in the overall stability of the embroidery needle is not very good, and the embroidery needle is easy to move and shake during the operation. For this reason, it is necessary to design a new technical solution to solve it. Utility Model Content

[0004] The utility model aims to overcome the deficiencies of the prior art, meet the actual needs, and provide an embroidery machine head to solve the problem that the current traditional embroidery machine head can only conveniently disassemble and assemble the embroidery needle. In this disassembly and assembly method, a limiting top column is used to limit the positions of the two sides of the embroidery needle. However, the connection area between the limiting top column and the needle sleeve is low, and the pull block is movable through the spring pulling method. There is a situation that the pull block shakes and displaces during use, and the needle sleeve and the embroidery needle shake and displace together, resulting in the overall stability of the embroidery needle is not very good, and the embroidery needle is easy to move and shake during operation. Technical problems.

[0006] The cylinder is connected to the bottom end of the fixing seat by screws;

[0007] The disassembly and assembly mechanism is connected to the bottom of the cylinder by screws, which can not only conveniently disassemble and assemble the embroidery machine head, but also limit and clamp the embroidery machine head, thereby improving the stability of the embroidery machine head during operation. The disassembly and assembly mechanism includes a limit housing, and a threaded rod runs through the inside of the limit housing;

[0008] A plug hole is provided at the bottom of the limiting shell, an embroidery needle body is inserted into the plug hole, one end of the embroidery needle body located in the limiting shell is detachably connected with a needle sleeve, a threaded rod passes through the needle sleeve, and nuts are threadedly connected at both ends of the threaded rod.

[0009] Preferably, both ends of the threaded rod are penetrated by fixing rings, the top of the fixing ring is connected to a telescopic tube by screws, and the top of the telescopic tube is connected to a fixing seat by screws.

[0010] Preferably, the telescopic cylinder includes a main telescopic cylinder, and the first and second auxiliary telescopic cylinders are penetrated by the upper and lower ends of the main telescopic cylinder, and the ends of the first and second auxiliary telescopic cylinders located in the main telescopic cylinder are respectively fixedly connected to the first damping block and the second damping block, and the ends of the first and second damping blocks away from the first and second auxiliary telescopic cylinders are fixedly connected to springs.

[0011] Preferably, the bottom of the limiting shell is connected to the limiting tube body by screws.

[0012] Preferably, both sides of the limiting tube body are connected with micro electric telescopic cylinders by screws, one side of the micro electric telescopic cylinder extends into the limiting tube body, and one end of the micro electric telescopic cylinder located in the limiting tube body is connected with an arc clamping plate by screws.

[0015] 1. The utility model combines the threaded rod, the needle sleeve and the fixing ring, not only can the threaded rod be used to limit the needle sleeve and the embroidery needle body, but also the needle sleeve and the embroidery needle body need to pass through the insertion hole of the limiting housing, so that the needle sleeve and the embroidery needle body can be double-limited and fixed. In addition, the threaded rod only needs to be pulled out to complete the rapid replacement operation of the embroidery needle body. Since the fixing ring passes through the threaded rod, the telescopic tube, spring and damping block on the top of the fixing ring can buffer the vibration of the threaded rod, the needle sleeve and the embroidery needle body. The disassembly and assembly mechanism is integrated with the vibration reduction mechanism, which solves the problem that the traditional embroidery machine head can only conveniently disassemble and assemble the embroidery needle. In this disassembly and assembly method, a limiting top column is used to limit the position of the two sides of the embroidery needle. However, the connection area between the limiting top column and the needle sleeve is low, and the pull block is movable through the spring pulling method. There is a situation that the pull block shakes and displaces during use, and the needle sleeve and the embroidery needle shake and displace together, resulting in the overall stability of the embroidery needle is not very good, and the embroidery needle is prone to displacement and shaking during operation. Technical problems.

[0016] 2. The utility model combines a limiting tube body, an electric telescopic cylinder and an arc-shaped clamping block. After the embroidery needle body passes through the limiting tube body and the insertion hole and enters the inside of the limiting shell, the electric telescopic cylinder drives the arc-shaped clamping block to clamp and limit the positions of the two sides of the embroidery needle body, thereby limiting and fixing the embroidery needle body, avoiding the problem of shaking and displacement of the embroidery needle body during use, and improving the stability of the embroidery needle body during operation.
