Therefore, a positioning and labeling mechanism for a special-shaped plastic box for contact lenses is proposed to solve the above-mentioned problems. Utility Model Content

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a contact lens special-shaped plastic box positioning labeling mechanism, comprising a dust cover, a transmission belt is connected to the lower side of the dust cover, a labeling mechanism for labeling the plastic box is arranged on the outer side of the dust cover, and a plurality of positioning mechanisms for positioning the plastic box are arranged on the outer side of the transmission belt;

The positioning and labeling mechanism for the special-shaped plastic box for contact lenses slides linearly left and right on the upper side of the positioning box through a connecting frame. At the same time, the suction force generated by the dust suction fan and the dust suction hose are used to absorb the dust on the surface of the plastic box and transfer it to the dust suction box, so that the labeling can be more firm.

[0016] 2. The positioning labeling mechanism for the special-shaped plastic box for contact lenses drives the turntable by a driving motor to rotate the labeling head in a circle, and labels according to the induction between the plastic box and the sensor, which solves the problem that some dust will adhere to the surface of the plastic box during the use of the positioning labeling device. During the labeling period, dust is likely to adhere to the surface of the label, which is more likely to fall off, resulting in the problem of weak label adsorption.

The positioning mechanism 3 comprises a positioning box 10 fixedly connected to the outer surface of the transmission belt 2, a connecting frame 14 slidably connected to the outer side of the positioning box 10, a dust collecting box 15 fixedly connected to the upper right end of the connecting frame 14, two dust collecting fans 18 embedded and installed on the right side surface of the dust collecting box 15, an adsorption pad 17 slidably connected to the inner wall of the dust collecting box 15, a dust collecting hose 16 connected to the left side of the dust collecting box 15, and a positioning mechanism arranged on the inner side of the positioning box 10.

[0024] Among them, the labeling mechanism includes a driving motor 9 fixedly mounted on the front end surface of the dust cover 1, a rotating shaft 4 fixedly connected to the output end of the driving motor 9, a turntable 5 fixedly sleeved on the outside of the rotating shaft 4, four electric push rods 6 fixedly mounted on the surface of the turntable 5, a labeling head 7 fixedly connected to the telescopic end of the electric push rod 6 and a sensor 8 embedded in the labeling head 7. The positioning mechanism includes a pull rod 11 slidably sleeved on the left and right sides of the positioning box 10, a spring 12 fixedly connected to the opposite side of the two pull rods 11 and a mold box 13 fixedly connected to the side of the pull rod 11 close to the spring 12. Slide grooves are provided on the left and right sides of the positioning box 10. The lower side of the connecting frame 14 is slidably connected in the slide groove. The left end of the upper side of the connecting frame 14 is fixedly connected with a handle. The four electric push rods 6 are arranged equidistantly in a circle.

[0025] The working principle of the above embodiment is:

[0026] The special-shaped plastic box is placed between two mold boxes 13 for shaping. In order to avoid the adhesion of dust and reduce the adsorption, the suction force generated by the dust suction fan 18 on one side of the dust suction box 15 is transmitted from the lower end of the dust suction hose 16 to the upper end of the plastic box to adsorb the dust attached to the surface. The connecting frame 14 reciprocates on the front and back sides of the positioning box 10 to absorb the dust at different positions of the plastic box. Then, the driving member drives the transmission belt 2 to drive the positioning box 10 and the plastic box to move into the dust cover 1. At the same time, the driving motor 9 on the surface of the dust cover 1 is synchronously turned on and drives the turntable 5 to rotate in a circle. When the sensor 8 in the labeling head 7 senses that an object is moving from below, the driving motor 9 will stop rotating, and the transmission belt 2 will also be disconnected. The output end of the electric push rod 6 drives the labeling head 7 to move linearly downward to fit and extrude the upper surface of the plastic box to complete the labeling.
