[0023] Please refer to Figure 2 Figure 3 ​​In the embodiment, the second screw rod support seat 8 is provided with a driven synchronous wheel 19 connected with the double screw rod 5 at the center of the surface, the driven synchronous wheel 19 is provided with a driving synchronous wheel 20 away from the right side of the connecting frame 24, the driving synchronous wheel 20 is provided with a synchronous belt 21 in transmission connection with the surface of the driven synchronous wheel 19, which can realize efficient and stable power transmission, avoid the slip phenomenon in the traditional transmission, ensure the driving force of the stepping motor 22 to be accurately transmitted to the double screw rod 5, thereby improving the synchronization and precision of the opening and closing action of the left and right blocking pieces 4, the driving synchronous wheel 20 is provided with a motor seat 12 fixedly connected with the bending frame 1, the motor seat 12 is provided with the stepping motor 22 in rotation connection with the driving synchronous wheel 20 at the front end, the driving synchronous wheel 20 is provided with the motor seat 12 fixedly connected with the bending frame 1, and the stepping motor 22 is provided at the front end of the motor seat 12 in rotation connection with the driving synchronous wheel 20, which can ensure the stable fixation of the stepping motor 22, reduce the vibration and displacement during operation, and improve the reliability of the transmission system. At the same time, the fixed connection of the motor seat 12 and the bending frame 1 enhances the rigidity of the overall structure, so that the power output of the stepping motor 22 is more accurate and stable.

[0024] Please refer to Figure 3 Figure 4 In the embodiment, the left screw rod nut 9 is provided with an induction sheet 13 away from the center of the left connecting frame 2, and the induction sheet 13 is provided with a slot photoelectric support 14 at the lower end, which can realize accurate detection of the position of the left screw rod nut 9. Through the cooperation of the slot photoelectric switch and the induction sheet 13, the movement state of the left screw rod nut 9 can be monitored in real time, and the signal can be fed back to the control system, so that the opening and closing positions of the left and right blocking pieces 4 are accurate. The slot photoelectric support 14 is provided with a detection slot photoelectric switch 23 away from the stepping motor 22, which can accurately detect the position of the left screw rod nut 9 and feed back the signal to the control system in time. Through the real-time monitoring of the detection slot photoelectric switch 23, it can be ensured that the left and right blocking pieces 4 accurately reach the preset position during the opening and closing process, and packaging errors caused by position deviation are avoided.

[0025] ​In the process of working, the stepper motor 22 is started according to the instruction of the control system, drives the double screw rod 5 to rotate through the synchronous belt 21, and the left-hand screw rod nut 9 and the right-hand screw rod nut 10 at both ends of the double screw rod 5 move in opposite directions. The left-hand screw rod nut 9 and the right-hand screw rod nut 10 drive the left connecting frame 2 and the right connecting frame 24 to slide along the guide rail 17 through the connecting plate 6 respectively, and the sliding block 16 on the left connecting frame 2 and the right connecting frame 24 ensures smooth movement without shaking. The left connecting frame 2 and the right connecting frame 24 drive the left blocking piece 3 and the right blocking piece 4 to move inward or outward respectively, and the opening and closing range of the blocking piece is determined by the rotation angle of the stepper motor 22, which ensures that the required material width is covered, and the material is positioned and blocked. When the left and right blocking pieces 4 are opened to the maximum set position, gloves or other materials are sent into the blocking area, and the groove-shaped photoelectric switch monitors the position of the blocking piece in real time to ensure that it stays in the correct position. The stepper motor 22 rotates in reverse to drive the left and right blocking pieces 4 to move inward and fix the material in the specified area. The minimum position of the blocking piece is detected and confirmed by the photoelectric switch to ensure that the material does not shift, and then packaging can be performed.

[0026] Through the above steps, the opening and closing actions of the left and right blocking pieces 4 are completely synchronized through the cooperation of left-hand and right-hand threads, avoiding errors caused by inconsistent unilateral movement. The stepper motor 22 can accurately control the rotation angle to achieve precise adjustment of the position of the blocking piece. The entire opening and closing process is driven by the stepper motor 22 without the need for manual intervention. At the same time, the automatic cutting mechanism can quickly cut off the material after packaging is completed. The opening and closing travel of the blocking piece can be flexibly set by adjusting the rotation angle of the stepper motor 22 to adapt to the needs of products of different sizes. The black insulating sleeve 15 effectively prevents electrical interference and protects the safety of the equipment and operating personnel. Even if the stepper motor 22 has a small error, the photoelectric switch can correct it in time to ensure stable operation of the equipment. The synchronous belt 21 transmission system has no slipping phenomenon, and the power transmission is stable and reliable. The existing blocking mechanisms on the market are mostly rotary or up-down lifting types, which cannot block high-position materials. Moreover, traditional packaging machines may use unilateral drive or non-synchronous transmission methods, which can cause the opening and closing actions of the left and right blocking pieces 4 to be out of sync.
