There are intermediate plates 135 between the right-angle groove 138 and the adjacent rectangular grooves 133, and between the adjacent rectangular grooves 133. The front side of each intermediate plate 135 is provided with an intermediate plate waist groove 136, and the rear side of each intermediate plate 135 is provided with an intermediate plate pin 137. A right-angle plate 140 is provided in each rectangular groove 133, and two right-angle plate pins 142 are provided on the right-angle side of the right-angle plate 140. The two right-angle plate pins 142 are slidably connected to the corresponding two rectangular grooves. shaped groove guide hole 134, a right angle plate vertical pin 143 is provided on the rear side of the right angle plate pin 142 on the left side, the right angle plate vertical pin 143 is slidably connected to the corresponding middle plate waist groove 136, and a No. 2 spring 190 is provided between each corresponding right angle plate vertical pin 143 and the middle plate pin 137, and the two sides of the No. 2 spring 190 are respectively fixedly connected to the corresponding right angle plate vertical pin 143 and the middle plate pin 137, and there is a gap between the bottom of each right angle plate 140 and the bottom of the rectangular groove 133, and the lower part of the middle rod cross pin 152 of each middle rod 150 is slidably connected to the inclined surface 141 at the front of the corresponding right angle plate 140 or the inclined surface of the right angle groove 138.

[0029] The rigidity of the No. 3 spring 210 is greater than that of the No. 2 spring 190. When the driving rod 160 corresponding to each rectangular slot 133 is pushed to the left, the corresponding intermediate rod 150 is pushed to the left under the drive of the driving rod 160, the No. 1 spring 180 is compressed, and when the intermediate rod 150 moves to the left, the intermediate rod cross pin 152 slides along the inclined surface 141 of the corresponding right-angle plate 140, the right-angle plate 140 is pushed to the rear side, and the No. 2 spring 190 is compressed. When the intermediate rod 150 moves to the leftmost side, the intermediate rod cross pin 152 moves to the bottom of the right-angle plate 140, and the right-angle plate 140 is reset under the action of the No. 2 spring 190, and the intermediate rod cross pin 152 is stuck at the bottom of the corresponding right-angle plate 140 and In the gap at the bottom of the rectangular groove 133, the middle rod 150 remains at the current position and does not move. When the middle rod 150 moves to the left, it drives the baffle 170 connected thereto to move to the left, and the material 410 on the conveyor belt 400 is blocked. When the driving assembly 300 moves from front to back, each baffle 170 is pushed out in turn, and the material 410 on the conveyor belt 400 is intercepted by each baffle 170 in turn. The material is precisely changed in distance, and the material in a group of baffles 170 is grouped. When the driving assembly 300 moves to the driving rod 160 on the rear side, the driving rod 160 and the middle rod 150 on the rear side are pushed, and the middle rod 150 on the rear side is pushed. The middle bar cross pin 152 of the rod 150 slides along the inclined surface of the right-angle groove 138, and the driving plate 130 is pushed to move backward by the middle bar cross pin 152, and the No. 3 spring 210 is compressed. When the middle bar 150 on the rear side moves to the leftmost side, the middle bar cross pin 152 of the front group of middle bars 150 is disengaged from the gap between the right-angle plate 140 and the rectangular groove 133, and a group of middle bars 150 and baffles 170 are quickly and synchronously reset under the action of the No. 1 spring 180. Since a group of middle bars 150 and baffles 170 are reset at the same time, a group of materials that are grouped and variable in distance begin to be transported downward at the same time. When the middle bar 150 on the rear side is After 150 moves to the leftmost side, the corresponding driving rod 160 slides over the cam 320, and the middle rod 150 on the rearmost side is reset under the action of the corresponding spring No. 180, and the driving plate 130 is also reset under the action of the spring No. 3 210, and then the motor 240 reverses, and the driving assembly 300 quickly moves to the front side to start the pitch change and grouping of the next group of materials. Since the speed of the motor 240 can be adjusted, the rhythm of grouping and pitch change can be adjusted according to the rhythm of grouping and pitch change of the conveyor belt 400. The distance between a group of baffles 170 is accurate, and a group of baffles 170 is quickly reset at the same time, which ensures the accurate distance adjustment of the material.

[0030] An operating method of an acupuncture instrument assembly auxiliary device includes the following steps: a first step, when the device is in the initial position, the driving component 300 is at the frontmost side of the device; a second step, when the material 410 on the conveyor belt 400 begins to be conveyed, the motor 240 is started, and the motor 240 drives the lead screw 230 to rotate when it rotates, and the lead screw 230 drives the driving component 300 to move backward, and the cam 320 pushes the driving rod 160 and the corresponding middle rod 150 to the left in sequence from front to back, and the baffles 170 extend to the left in sequence, and the materials are intercepted by a group of baffles 170 in sequence. After the driving component 300 pushes the driving rod 160 on the rear side, a group of baffles 170 quickly resets, and the grouped and variable-length materials begin to be transferred to the next process by the conveyor belt 400.

[0031] The driving assembly 300, the base 110, the driving rod 160, the intermediate rod 150, the gear 220, the driving plate 130, and the right-angle plate 140 cooperate with each other to achieve the purpose of a group of intermediate rods 150 and baffles 170 being pushed in sequence and quickly reset at the same time, ensuring that the materials can be intercepted and grouped in sequence, and that the materials after the grouping distance change can be sent out at the same time. The distance between a group of baffles 170 is accurate, ensuring the accurate distance adjustment and grouping of the materials. The action time of each baffle 170 can be controlled by the speed of the motor 240, so that the device can adapt to the adjustment of the rhythm of the production line. The driving assembly 300, the base 110, the driving rod 160, the intermediate rod 150, and the gear 220 cooperate with each other to enlarge the pushing distance of the driving rod 160, making the device more compact.
