[0017] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0018] This utility model provides, for example Figure 1-5 The positioning and guiding structure of a contact lens packaging line shown includes a guiding component 3 disposed between the contact lens conveyor belt 1 and the packaging box conveyor belt 2. The guiding component 3 guides the contact lens 4 from the contact lens conveyor belt 1 to the packaging box 5 on the packaging box conveyor belt 2 through an external pushing structure. The material guiding assembly 3 includes a base 31, with symmetrical material guiding plates 32 mounted on the top of the base 31. The contact lens 4 passes directly through the symmetrical material guiding plates 32. The top of the base 31 is provided with multiple adjustment slots 33, and multiple positioning rods 34 are provided in the adjustment slots 33. The bottom of the material guiding plate 32 is provided with a moving plate 321 that matches the adjustment slots 33. The moving plate 321 is provided with positioning holes 322 that match the positioning rods 34. A locking assembly 6 is provided on the outer side of the moving plate 32 in the middle, which locks the material guiding plate 32 onto the positioning rods 34.

[0019] Specifically, a moving groove 323 is provided on the outer side of the moving plate 321 below the center of the guide plate 32, located on both sides of the positioning hole 322. A limiting groove 324 is provided in the moving groove 323, and a locking component 6 is installed in the moving groove 323 and the limiting groove 324.

[0020] Specifically, the locking assembly 6 includes two locking blocks 61. The opposite sides of the two locking blocks 61 are provided with arc-shaped grooves 62 that match the positioning rods 34. The back of the locking block 61 is provided with a moving block 63 that matches the moving groove 323. The bottom edge of the moving block 63 is provided with a limiting strip 631 that matches the limiting groove 324. The inner locking block 61 is provided with a positioning strip 611 on one side and a positioning groove 612 that matches the positioning strip 611 on one side. The locking blocks 61 are also provided with corresponding locking grooves 64. A fastening plate 65 is inserted into the locking groove 64.

[0021] Specifically, the locking blocks 61 on both sides are staggered. When the arc grooves 62 are both matched and tightly attached to the outer wall of the positioning rod 34, the locking grooves 64 on both sides correspond. The inner wall of one locking groove 64 is provided with vertical moving grooves 641 on both sides. The bottom of the fastening plate 65 is provided with vertical moving blocks 651 that match the vertical moving grooves 641. The fastening plate 65 is set in the locking groove 64 on one side. When the locking grooves 64 on both sides correspond, the fastening plate 65 is inserted into the locking grooves 64 on both sides from the top.

[0022] Specifically, the fastening plate 65 has anti-slip textures 652 on both sides of its top.

[0023] Specifically, each locking block 61 has multiple evenly spaced push-pull grooves 613 on one side of its top. The top area of ​​the outer locking block 61 is larger than that of the inner locking block 61. The length of the movable block 63 fixed on one side of the two locking blocks 61 is adapted to their positional relationship.

[0024] Specifically, the ends of the two guide plates 32 are designed as symmetrical arcs.

[0025] In this embodiment, the guide assembly 3 is first installed between the contact lens conveyor belt 1 and the packaging box conveyor belt 2, ensuring that the base 31 is horizontally fixed and the ends of the two conveyor belts are aligned with the inlet and outlet of the guide plate 32. The movable plate 321 at the bottom of the guide plate 32 is embedded into the adjustment groove 33 of the base 31, so that the guide plates 32 are symmetrically distributed, with the arc-shaped structure at the end facing the side of the contact lens conveyor belt 1. The positioning rod 34 is inserted into the preset installation position of the adjustment groove 33, so that the positioning hole 322 on the movable plate 321 fits onto the outside of the positioning rod 34, initially defining the position of the guide plate 32. Assemble the locking assembly 6: Insert the moving blocks 63 of the two locking blocks 61 into the moving grooves 323 of the moving plate 321, and the limiting strips 631 are inserted into the limiting grooves 324; the positioning strips 611 of the inner locking block 61 are inserted into the positioning grooves 612 of the outer locking block 61, so that the two locking blocks 61 are staggered and fitted together.

[0026] In this embodiment, according to the specifications of the contact lens 4, the guide plate 32 is moved along the adjustment groove 33 to adjust the distance between the two guide plates 32, ensuring that the contact lens 4 can pass through smoothly without deviation. After the distance is determined, the locking blocks 61 on both sides are pushed so that the arc groove 62 completely fits the outer wall of the positioning rod 34. At this time, the locking grooves 64 of the locking blocks 61 on both sides are precisely aligned. The fastening plate 65 is inserted into the aligned locking groove 64 from the top, so that the vertical moving block 651 is embedded in the vertical moving groove 641. The anti-slip texture 652 presses the fastening plate 65 to the bottom, completing the locking of the guide plate 32.

[0027] In this embodiment, the contact lens conveyor belt 1 and the packaging box conveyor belt 2 are activated. The packaging box 5 moves at a constant speed along the packaging box conveyor belt 2 to below the outlet of the guide assembly 3. The external pushing structure pushes the contact lenses 4 on the contact lens conveyor belt 1 between the two guide plates 32, and they enter the guide channel along the arc-shaped ends of the guide plates 32. Under the limiting action of the symmetrical guide plates 32, the contact lenses 4 accurately fall into the corresponding packaging box 5 below, completing the positioning and guiding process.

[0028] In this embodiment, the guide plate 32 can move laterally along the positioning rod 34 through the cooperation of the moving plate 321 and the adjusting groove 33. Combined with the arrangement of multiple adjusting grooves 33 and positioning rods 34, it can quickly adapt to contact lenses 4 of different sizes. The disassembly and locking operation of the locking assembly 6 is simple; the position of the locking block 61 can be easily adjusted through the push-pull groove 613, and the spacing adjustment can be completed without complex tools.

[0029] In this embodiment, the arc-shaped groove 62 of the locking block 61 fits tightly against the positioning rod 34, and together with the positioning strip 611 and the positioning groove 612, it prevents the guide plate 32 from shifting during the material guiding process. The fastening plate 65, through the limiting of the vertical moving block 651 and the vertical moving groove 641, ensures that the locking assembly 6 does not loosen after locking, further ensuring the consistency of the material guiding path.

[0030] In this embodiment, the ends of the guide plates 32 adopt a symmetrical arc design to reduce collisions and jamming when the contact lenses 4 enter the guide channel, thereby reducing the risk of product damage. The inner wall of the guide channel formed by the two guide plates 32 is smooth, which, together with the uniform speed of the conveyor belt, enables a smooth transition of the contact lenses 4 from the conveyor belt to the packaging box.

[0031] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
