[0002] Template sewing machines refer to fully automated template production that combines garment template CAD software, garment template sewing CAD software, and advanced CNC technology. This facilitates fully automated garment sewing, promotes the assembly line production of garment templates, and improves production efficiency and product quality. The transmission mechanism of a template sewing machine is a mechanical system used to drive the sewing template to move in a two-dimensional plane in conjunction with the sewing machine head to complete automated sewing.

[0003] However, existing transmission mechanisms typically rely on servo motors to control their movement. During high-speed operation of the sewing machine, intense mechanical vibrations can cause power and signal cables to loosen or detach, potentially leading to control malfunctions or motor stalling due to poor contact. Therefore, those skilled in the art have provided a template transmission mechanism for a template sewing machine to address the problems described in the background section. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a template transmission mechanism for a template sewing machine, which solves the problems mentioned in the background section.

A washer is movably sleeved on the outer sides of the upper and lower half-threaded columns, and a metal nut is threadedly connected to the outer sides of the upper and lower half-threaded columns.

[0007] As a further improvement of this utility model: the limiting protective sleeve and the servo motor are fixedly connected, and the outer wall of the metal nut is knurled.

[0008] As a further improvement of this utility model: a line interface is provided on one side of the outer wall of the servo motor, and the corresponding surfaces of the limiting protective sleeve and the limiting reinforcement sleeve are fitted together.

[0013] This utility model provides a template transmission mechanism for a template sewing machine, which has the following advantages compared with the prior art:

[0014] 1. This design discloses a template transmission mechanism for a template sewing machine. By incorporating a limit reinforcement mechanism, the limit reinforcement sleeve and limit protection sleeve are easily fixed. These sleeves reinforce the power and signal cables outside the servo motor, physically securing them to prevent loosening or detachment due to vibration. Furthermore, the mechanism blocks external dust and oil, reduces damage from mechanical collisions, and minimizes control malfunctions or motor stoppages caused by poor contact, thus ensuring the stability of the template transmission in the template sewing machine.

[0015] 2. The template transmission mechanism of the template sewing machine designed in this paper has a stabilizing mechanism. The support spring absorbs vibration energy through elastic deformation, and the damper can quickly dissipate energy, significantly reducing the risk of resonance. This avoids structural damage or accuracy deviation caused by high-frequency vibration of the servo motor. By controlling the vibration amplitude, it reduces faults such as loose connecting parts and disconnected lines, ensuring the continuous production needs of the template transmission of the template sewing machine.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0022] Please see Figure 1-4 This utility model provides a technical solution for a template transmission mechanism of a template sewing machine: A template transmission mechanism for a template sewing machine includes a mounting housing 1, an assembly bracket 2 fixed on one side of the mounting housing 1, a servo motor 3 fixed on one side of the assembly bracket 2, a ball screw 4 fixed at one end of the output shaft of the servo motor 3, a ball nut threadedly connected to the outer side of the ball screw 4, a movable bracket 5 fitted on the top of the ball nut, a limit sleeve 6 fixed at the bottom of the movable bracket 5, a limit track 7 installed on the top of the mounting housing 1, a limit reinforcement mechanism 8 provided on the outer side of the servo motor 3, and a stabilizing mechanism 9 connected to the outer side of the assembly bracket 2;

[0023] like Figure 1-3As shown, the limiting and reinforcing mechanism 8 includes a limiting protective sleeve 81. Lower threaded posts 82 are fixed to both sides of the limiting protective sleeve 81. A guide groove 83 is provided on the outer wall of the servo motor 3. An anti-disengagement slider 84 is slidably connected to the servo motor 3 through the guide groove 83. A limiting and reinforcing sleeve 85 is fixed to the bottom of the anti-disengagement slider 84. Upper threaded posts 86 are fixed to both sides of the limiting and reinforcing sleeve 85. A gasket 8 is movably fitted onto the outer sides of both the upper threaded posts 86 and the lower threaded posts 82. 7. The outer sides of the upper threaded post 86 and the lower threaded post 82 are connected by a metal nut 88. The limiting protective sleeve 81 and the servo motor 3 are fixedly connected. The outer wall of the metal nut 88 is knurled. A line interface is provided on one side of the outer wall of the servo motor 3. The corresponding surfaces of the limiting protective sleeve 81 and the limiting reinforcement sleeve 85 are fitted together. The inner walls of the limiting protective sleeve 81 and the limiting reinforcement sleeve 85 are both provided with arc grooves. The radius of the upper threaded post 86 and the radius of the lower threaded post 82 are equal.

[0024] like Figure 1 and Figure 4 As shown, the stabilizing mechanism 9 includes a fixed frame 91, a fixed housing 92 fixed to the top of the fixed frame 91, a support spring 93 provided on the inner bottom wall of the fixed housing 92, a lifting plate 94 fixed to the top of the support spring 93, a support sleeve 95 installed on the top of the lifting plate 94, a connecting sleeve 96 fixed to the top of the support sleeve 95, and a damper 97 installed at the bottom of the lifting plate 94. The fixed frame 91 and the assembly bracket 2 are fixedly connected, and the fixed housing 92 and the fixed frame 91 are welded together. The top of the connecting sleeve 96 is provided with an arc-shaped groove, which is adapted to the outer wall size of the servo motor 3.

[0025] The working principle of this utility model is as follows: By setting a limiting reinforcement mechanism 8, after the servo motor 3 and the corresponding power line and signal line are connected, one end of the power line and signal line are inserted into the servo motor 3. At this time, the outer wall of the power line and signal line is in contact with the inner wall of the arc-shaped groove opened by the limiting reinforcement mechanism 8. Then, the anti-disengagement slider 84 is pushed down, so that the anti-disengagement slider 84 drives the limiting reinforcement sleeve 85 to move, so that the upper half threaded post 86 on the outside of the limiting reinforcement sleeve 85 and the lower half threaded post 82 on the outside of the limiting protective sleeve 81 are in contact. Then, the washer 87 is movably sleeved on the outside of the lower half threaded post 82 and the upper half threaded post 86. Then, the metal nut 88 is threadedly connected to the lower half threaded post 82 and the upper half threaded post 86, which conveniently completes the fixing of the limiting reinforcement sleeve 85 and the limiting protective sleeve 81, so that the limiting protective sleeve 81 and the limiting reinforcement sleeve 85 reinforce the outside of the power line and signal line on the outside of the servo motor 3. By physically fixing the power line and signal line, the power line is prevented from being damaged by vibration. This system addresses issues such as loose or detached wiring and signal lines, and also blocks external dust, oil, and reduces damage from mechanical collisions. It minimizes control malfunctions or motor stoppages caused by poor contact, ensuring the stability of the template transmission in the template sewing machine. With a stabilizing mechanism 9, after the servo motor 3 is fixedly connected to the mounting housing 1 via the mounting bracket 2, a fixing frame 91 is fixed to the outside of the mounting bracket 2. The damper 97 and support spring 93 within the fixing frame 91 lift the lifting plate 94. The connecting sleeve 96 at the top of the support sleeve 95 corresponds to the servo motor 3, providing auxiliary support to the bottom of the servo motor 3. During operation, the support spring 93 absorbs vibration energy through elastic deformation, and the damper 97 quickly dissipates energy, significantly reducing the risk of resonance and preventing structural damage or accuracy deviation caused by high-frequency vibration of the servo motor 3. By controlling the vibration amplitude, it reduces faults such as loose connections and detached wiring, ensuring the continuous production needs of the template sewing machine's template transmission.

[0026] The above are merely preferred embodiments of this utility model. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principles of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model.
