Technical Field

[0001] The utility model belongs to the technical field of contact lens packaging boxes, and particularly relates to a labeling and positioning device for contact lens packaging boxes. Background Art

[0002] A contact lens packaging box is a product container specifically designed to store and protect contact lenses or colored contact lenses. When performing production operations, a special labeling and positioning device for contact lens packaging boxes is required to perform labeling operations on them.

[0003] A labeling and positioning device for contact lens packaging boxes with the authorization announcement number of CN 220363592 U includes a fixed frame. A conveyor belt is movably installed inside the fixed frame. A support frame is fixedly installed at the upper end of the conveyor belt. A hydraulic cylinder is fixedly installed at the upper end of the support frame. The lower end of the hydraulic cylinder penetrates through the inner cavity of the upper end of the support frame and is fixedly connected to the upper end of the labeling mechanism. Moving motors are fixedly installed on both sides of the upper end of the fixed frame. A moving lead screw is movably connected to one side of the moving motor. The labeling and positioning device for contact lens packaging boxes of the utility model can, through the moving and sliding mechanisms, adjust the distance and height of two clamping plates to perform positioning adjustment on packaging boxes of different sizes.

[0004] Although it can achieve positioning of packaging boxes of different sizes, there are still some problems in daily use. When driving the clamping plates to adapt to various size changes, it relies on the coordinated work of multiple motors, which inevitably raises the initial equipment investment cost, not only increases the assembly and debugging difficulty, but also puts forward higher requirements for the later maintenance work, and may also lead to an increase in maintenance costs and an extension of downtime, affecting the overall operation efficiency. Content of the Utility Model

[0005] In view of this, the utility model provides a labeling and positioning device for contact lens packaging boxes, which can complete all displacement adjustments with only a single motor through the positioning mechanism, effectively reducing the initial equipment cost and simplifying the later maintenance work, avoiding an increase in maintenance costs and an extension of downtime, and improving the overall operation efficiency.

[0006] To solve the above technical problems, the present utility model provides a labeling positioning device for a contact lens packaging box, which includes an electric conveyor belt and a positioning mechanism arranged on the electric conveyor belt. The positioning mechanism includes slide holes symmetrically arranged on the upper left and right sides of the front and back surfaces of the electric conveyor belt respectively. Slide rods are slidably connected in the slide holes, and the slide holes provide sliding guiding support for the slide rods. Positioning plates are provided at the inner ends of the two laterally adjacent slide rods, and the slide rods provide fixed support for the positioning plates. Connecting frames are provided at the outer ends of the two laterally adjacent slide rods, and the slide rods provide fixed installation support for the connecting frames. A U-shaped plate is provided in the middle of the upper surface of the electric conveyor belt. A bidirectional lead screw is rotatably connected between the rotation holes longitudinally symmetrically arranged on the front and back wall surfaces of the U-shaped plate, and the rotation holes provide rotational support for the bidirectional lead screw. Sleeve nuts are rotatably connected in the rotation holes provided in the middle of the inner ends of the upper sides of the connecting frames, and the rotation holes provide rotational support for the sleeve nuts. The front and rear ends of the bidirectional lead screw are respectively meshed and connected with the adjacent sleeve nuts on the same side.

[0007] The positioning mechanism further includes worm wheels respectively arranged on the outer arc surfaces of the sleeve nuts. A worm is rotatably connected between the upper left and right wall surfaces of the inner cavity of the connecting frame, and the connecting frame provides rotational support for the worm. The worm is respectively meshed and connected with the adjacent worm wheels on the same side. The right ends of the worms respectively pass through the corresponding openings provided on the connecting frames and extend to the outside, which can not only adjust the rotation of the sleeve nuts but also limit the sleeve nuts by using the self-locking characteristic of the meshing of the worm and the worm wheel.

[0008] The positioning mechanism further includes a motor arranged on the front surface of the U-shaped plate. The rear end of the output shaft of the motor is fixedly connected with the front end of the bidirectional lead screw, which serves to drive the bidirectional lead screw to rotate.

[0009] Rotating rollers are rotatably connected in the rotation grooves evenly arranged horizontally on the inner side surfaces of the positioning plates, which reduces the friction coefficient between the positioning plates and the contact lens packaging box; the rotating rollers are rubber rotating rollers.

[0010] Scale lines are provided on the outer arc surfaces of the slide rods, which is convenient for the staff to visually observe the moving distance of the slide rods.

[0011] The electric conveyor belt and the motor are both electrically connected to an external single-chip microcomputer to control the operation of each electrical component.

[0012] The beneficial effects of the above technical solutions of the present utility model are as follows:

[0013] 1. First, the relevant staff control the operation of the electric conveyor belt through an external single-chip microcomputer. The electric conveyor belt operates to transport the contact lens packaging boxes to be labeled. Meanwhile, it is restricted by two positioning plates to ensure that the contact lens packaging boxes move along a predetermined path. When encountering contact lens packaging boxes of different sizes, the relevant staff control the operation of the motor through an external single-chip microcomputer. The output shaft of the motor rotates to drive the double-threaded screw to rotate synchronously. When the double-threaded screw rotates, it drives the connecting frame, sliding rod, and positioning plate to move outward or inward synchronously through the double-threaded screw driving connection engaged with it, so as to meet the positioning requirements of contact lens packaging boxes of different sizes. Only a single motor is required to complete all displacement adjustments, effectively reducing the initial equipment cost and simplifying the later maintenance work, avoiding the increase in maintenance costs and the extension of downtime, and improving the overall operation efficiency.

[0014] 2. First, rotate the worm according to the shape of the contact lens packaging box. When the worm rotates, it drives the wire sleeve to rotate through the worm gear engaged with it. When the wire sleeve rotates, it drives the connecting frame, sliding rod, and positioning plate to move along the sliding hole through the double-threaded screw, thereby changing the relative position of a single positioning plate to meet the labeling requirements at different positions of the contact lens packaging box, and enabling different labeling positions of the contact lens packaging box to always be in the middle of the electric conveyor belt, greatly enhancing the flexibility and versatility of the labeling device.

[0015] 3. The rotating roller prevents the contact lens packaging box from being scratched and damaged during movement. Description of the Drawings

A U-shaped plate 203 is arranged in the middle of the upper surface of the electric conveyor belt 100. The U-shaped plate 203 is fixedly installed in the middle of the upper surface of the electric conveyor belt 100. A bidirectional lead screw 204 is rotatably connected between the rotation holes symmetrically arranged on the front and rear wall surfaces of the U-shaped plate 203. The bidirectional lead screw 204 is rotatably connected between the two rotation holes, and the rotation holes provide rotational support for the bidirectional lead screw 204. Sleeve nuts 205 are rotatably connected in the rotation holes arranged in the middle of the inner ends of the upper sides of the connection frames 202 respectively. The sleeve nuts 205 are respectively rotatably connected in the rotation holes, and the rotation holes provide rotational support for the sleeve nuts 205. The front and rear ends of the bidirectional lead screw 204 are respectively meshed and connected with the adjacent sleeve nuts 205 on the same side; the positioning mechanism further includes worm wheels 206 respectively arranged on the outer arc surfaces of the sleeve nuts 205. The worm wheels 206 are respectively fixedly installed in the middle of the outer arc surfaces of the sleeve nuts 205.

The connection frame 202 provides rotational support for the worm 207. The worm 207 is respectively meshed and connected with the adjacent worm wheels 206 on the same side. The right ends of the worm 207 respectively pass through the corresponding openings on the connection frame 202 and extend to the outside, which can not only adjust the rotation of the sleeve nut 205 but also limit the sleeve nut 205 by using the self-locking characteristic of the meshing of the worm 207 and the worm wheel 206; the positioning mechanism further includes a motor 208 arranged on the front surface of the U-shaped plate 203.

[0026] The working principle of a labeling positioning device for a contact lens packaging box provided by the present utility model is as follows: First, rotate the worm 207 according to the shape of the contact lens packaging box. When the worm 207 rotates, it drives the silk sleeve 205 to rotate through the worm gear 206 engaged therewith. When the silk sleeve 205 rotates, it drives the connecting frame 202, the sliding rod 200, and the positioning plate 201 to move along the sliding holes through the bidirectional lead screw 204, thereby changing the relative position of a single positioning plate 201 to meet the labeling requirements at different positions of the contact lens packaging box, enabling different labeling positions of the contact lens packaging box to always be in the middle of the electric conveyor belt 100, greatly enhancing the flexibility and versatility of the labeling device. First, relevant staff control the operation of the electric conveyor belt 100 through an external single-chip microcomputer. The electric conveyor belt 100 operates to convey the contact lens packaging box to be labeled for movement. At the same time, it is restricted by two positioning plates 201 to ensure that the contact lens packaging box advances along a predetermined path. When encountering contact lens packaging boxes of different sizes, relevant staff control the operation of the motor 208 through an external single-chip microcomputer. The output shaft of the motor 208 rotates to drive the bidirectional lead screw 204 to rotate synchronously. When the bidirectional lead screw 204 rotates, it drives the connecting frame 202, the sliding rod 200, and the positioning plate 201 to move outward or inward synchronously through the bidirectional lead screw 204 engaged therewith, so as to meet the positioning requirements for contact lens packaging boxes of different sizes. Only a single motor 208 is required to complete all displacement adjustments, effectively reducing the initial equipment cost and simplifying the subsequent maintenance work, avoiding the increase in maintenance costs and the extension of downtime, and improving the overall operation efficiency. The rotating rollers 300 prevent the contact lens packaging box from being scratched and damaged during movement.

[0027] As Figures 1-4 shown, scale lines 400 are provided on the outer arc surfaces of the sliding rods 200. The scale lines 400 are respectively fixedly arranged on the outer arc surfaces of the sliding rods 200, facilitating the staff to directly observe the distance moved by the sliding rods 200. The scale lines 400 facilitate the operator to adjust the specific position of the positioning mechanism.

[0028] In addition, it should be noted that in the description of the present utility model, unless otherwise clearly specified and defined, the terms "installation", "connection", and "coupling" should be understood in a broad sense. For example, it may be a fixed connection, a detachable connection, or an integral connection; it may be a mechanical connection or an electrical connection; it may be directly connected or indirectly connected through an intermediate medium, and it may be the communication inside two components. For those skilled in the art, the specific meanings of the above terms in the present utility model can be understood according to specific circumstances.

[0029] The above is the preferred embodiment of the present utility model. It should be pointed out that for those of ordinary skill in the art, without departing from the principle of the present utility model, several improvements and modifications can be made, and these improvements and modifications should also be regarded as the protection scope of the present utility model.
