Wherein, one end of the first threaded rod 302 far away from the output shaft of the rotating motor 301 is rotatably connected to the left side surface of the right side plate 1, the threaded cylinder 303 is slidably connected to the outer side of the limiting rod 305, the positioning assembly comprises a movable opening 306 arranged on the front surface of the take-up block 304, the movable opening 306 is used for a produced nose bridge strip to pass through and then is wound on the winding wheel 2, springs 307 are fixed on the left side surface and the right side surface of the take-up block 304, extrusion plates 308 are fixed on the opposite sides of the two springs 307, bolt rods 309 are fixedly arranged on the opposite sides of the two extrusion plates 308, the nose bridge strip can be fixed by the bolt rods 309 to prevent the nose bridge strip from loosening after the nose bridge strip is wound, rubber rings are fixed on the inner peripheral wall of the movable opening 306, the rubber rings are soft, so that the friction force generated when the nose bridge strip passes through can be reduced, the nose bridge strip is prevented from being worn off, the springs 307 are sleeved on the outer sides of the bolt rods 309, movable openings for inserting the bolt rods 309 are arranged on the left side and the right side surface of the take-up block 304, the movable hole is clearance fitted with the latch rod 309.

It can be understood that when the first threaded rod 302 rotates, the threaded cylinder 303 moves left and right on the outer side of the first threaded rod 302, and the two limiting rods 305 limit the threaded cylinder 303 to prevent it from rotating during the process of moving left and right.

It should be noted that, when the pressing plate 308 contacts the side plate 1, the pressing plate 308 will be subjected to a force, and this force will make the pressing plate 308 move towards the wire-rewinding block 304, and drive the latch rod 309 to move towards the corresponding direction, so as to complete the fixing of the nose bridge strip.

Referring to fig. 3, the auxiliary positioning mechanism 4 in this embodiment includes a dual-shaft motor 401 fixed on the right side of the right side plate 1, a second threaded rod 402 driven by the dual-shaft motor to make a circular motion is fixed on the outer side of the output shaft on both upper and lower sides of the dual-shaft motor 401, a sleeve 403 in which the outer side of the second threaded rod 402 makes a vertical linear motion is in threaded connection with the outer side of the second threaded rod, a connecting rod 404 is fixed on the left side surface of the sleeve 403, a positioning ring 405 is fixed on the opposite side of the two connecting rods 404, the positioning ring 405 is in a semicircular shape and can roll and fix a nose bridge strip, two sliding grooves 406 are formed on the right side surface of the left side plate 1, and a sliding block 407 is slidably connected inside the sliding grooves 406.

The right side face of the sliding block 407 and one end, far away from the sleeve 403, of the connecting rod 404 are fixed, two limiting plates are perpendicularly fixed to the right side face of the right side plate 1, the second threaded rod 402 is rotatably connected inside the limiting plates, and the limiting plates support and limit the second threaded rod 402.

It can be understood that, when the two sleeves 403 move relatively, the sliding block 407 slides inside the sliding slot 406, which also acts as a limit for the two sleeves 403 to prevent the sleeves 403 from rotating.

The working principle of the embodiment is as follows:

(1) when the nose bridge strip is rolled up, the two side plates 1 are static, the rolling wheel 2 rotates between the two side plates 1, in the rotating process of the rolling wheel 2, the nose bridge strip is wound on the outer surface of the rolling wheel 2 through the movable opening 306 in the front of the take-up block 304, so that the nose bridge strip is collected together and is rolled on the outer surface of the rolling wheel 2, after the rolling is finished, a worker drives the rotating motor 301 through driving the output shaft of the rotating motor 301 to rotate to drive the first threaded rod 302 to rotate, in the rotating process of the first threaded rod 302, the threaded cylinder 303 makes left-right linear motion on the outer side of the first threaded rod 302, the threaded cylinder 303 slides on the outer side of the limiting rod 305, when the threaded cylinder 303 moves to the leftmost side, the left side extrusion plate 308 is in contact with the right side surface of the left side plate 1, the extrusion plate 308 is forced to the right, and the left side spring 307 is compressed, the left latch rod 309 will move to the right, when the left latch rod 309 contacts the nose bridge bar, which is now secured.

(2) Then, the worker can cut off the rolled nose bridge strip, so that the joint left by the nose bridge head is fixed on the inner peripheral wall of the movable opening 306, the rolled nose bridge strip roll cannot loosen, the worker can also control the rotating motor 301 to move the threaded barrel 303 to the rightmost position, the right side extrusion plate 308 is in contact with the left side surface of the right side plate 1, the nose bridge strip can be fixed through the movement of the right side bolt rod 309, after the joint left by the nose bridge strip is fixed, the worker can control the double-shaft motor 401, at the moment, two output shafts of the double-shaft motor 401 start to rotate to drive the two second threaded rods 402 to rotate, because the thread directions of the outer surfaces of the two second threaded rods 402 are opposite, the two sleeves move relatively, when the rolled nose bridge strip roll needs to be pressed, the two sleeves 403 simultaneously move towards each other, the connecting rod 404 and the positioning ring 405 are driven to move towards the rolled nose bridge strip roll, when the locating ring 405 contacts with the nose bridge strip roll, the nose bridge strip roll is clamped by the two locating rings 405, and the phenomenon that the rolled nose bridge strip roll cannot loosen is guaranteed.
