DETAILED DESCRIPTION

[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] As attached Figure 1 To Attachment Figure 4 As shown:

[0023] Embodiment 1: The utility model provides a new head lifting structure of a fully automatic template sewing machine, including a main body 1, including a head bracket 101, and a head mechanism 102 arranged at the front end of the head bracket 101; a lifting mechanism 2, including a lifting component 201 arranged between the head bracket 101 and the head mechanism 102, an emergency stop component 202 arranged on the lifting component 201, and a connecting component 203 arranged between the lifting component 201 and the head mechanism 102.

[0024] Specifically, the lifting assembly 201 includes a fixed frame 2011 arranged on the top of the head bracket 101, a movable seat 2016 arranged on the top of the head mechanism 102, a reduction box 2013 arranged on the top of the fixed frame 2011, a motor 2012 arranged at the input end of the reduction box 2013, a screw rod 2014 arranged at the output end of the reduction box 2013, and a plum blossom limit column 2015 arranged at the bottom of the fixed frame 2011.

[0025] Furthermore, the screw rod 2014 is threadedly connected to the movable seat 2016 , and the plum blossom limiting column 2015 is slidably connected to the movable seat 2016 .

[0026] As can be seen from the above, when the motor 2012 is started during operation, the motor 2012 will drive the screw 2014 to rotate after being decelerated by the reduction gear box 2013, and then through the threaded connection between the screw 2014 and the movable seat 2016, the movable seat 2016 together with the machine head mechanism 102 will be driven to move up and down, and the plum blossom limit column 2015 will limit and guide the movable seat 2016 together with the machine head mechanism 102 to ensure the stability of the machine head mechanism 102 during the lifting process. The reduction gear box 2013 will reduce the speed of the motor 2012 driving the screw 2014, increase the torque, and ensure the lifting stability and lifting accuracy.

[0027] Embodiment 2: This embodiment is basically the same as the previous embodiment, except that the emergency stop assembly 202 includes guide rods 2021 arranged on both sides of the fixed frame 2011, a slider 2022 slidably arranged on the guide rods 2021, a pressure block 2025 arranged on both sides of the movable seat 2016, and an emergency stop button 2026 respectively arranged on both sides of the fixed frame 2011 and on the slider 2022.

[0028] Specifically, a limit bolt 2023 is threadedly provided on the slider 2022 , and an identification plate 2024 is provided at the rear end of the fixing frame 2011 .

[0029] Furthermore, the connecting assembly 203 includes a fixed plate 2031 arranged on both sides of the movable seat 2016, a connecting bolt 2032 respectively arranged between the head mechanism 102 and the movable seat 2016 and the fixed plate 2031, a reinforcement seat 2034 arranged at the rear end of the fixed frame 2011, and a connecting bolt 2033 respectively arranged between the head bracket 101 and the fixed frame 2011 and the reinforcement seat 2034.

[0030] As can be seen from the above, during the lifting process of the head mechanism 102, the pressing block 2025 will be driven to move synchronously. When the pressing block 2025 touches the emergency stop button 2026 upward or downward, the motor 2012 will be automatically powered off and stopped, so as to avoid the situation where the head mechanism 102 continues to move after moving to the highest or lowest position due to failure of the external control mechanism and the motor 2012, thereby causing structural damage. In addition, the staff can turn the limit bolt 2023 to release the limited state of the slider 2022, and then move the position of the emergency stop button 2026 under the instruction of the identification plate 2024, thereby controlling the machine. The maximum lifting distance of the head mechanism 102 can be determined by rotating the limit bolt 2023 to limit the position of the slider 2022 after completion. It can be adjusted according to actual needs to facilitate personnel use. The movable seat 2016 and the head mechanism 102 can be firmly fixed together through the connecting bolt 1 2032, and the fixed frame 2011 and the head bracket 101 can be firmly fixed together through the connecting bolt 2033 to ensure stability. When maintenance is required, the lifting mechanism 2 can be removed from the main body 1 by rotating the connecting bolt 1 2032 and the connecting bolt 2 2033 in turn, which is convenient for personnel to carry out maintenance work.
