[0023] The present utility model will be described in detail below. The technical solutions in the embodiments of the present utility model are clearly and completely described. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0024] The present utility model provides a feeding mechanism for coating a plastic multi-faceted rotating mirror through improvement. The technical solution of the present utility model is as follows:

[0025] As Figure 1 - Figure 3 shown, a feeding mechanism for coating a plastic multi-faceted rotating mirror includes a base 1. A groove is formed on the top wall surface of the base 1. A first motor 2 is arranged inside the groove. A rotating rod 21 is fixedly installed at the output end of the first motor 2. A second motor 3 is also included;

[0026] The second motor 3 is fixedly installed on the side wall of the base 1. A lead screw 31 is fixedly installed at the output end of the second motor 3. An opening groove 11 is formed on the top wall surface of the base 1. The lead screw 31 is rotatably installed on the inner side wall of the opening groove 11. A moving block 32 is spirally installed on the side wall of the lead screw 31. The moving block 32 is in a "T" shape. A sleeve 4 is rotatably installed on the side wall of the moving block 32. A limiting groove 41 is arranged inside the sleeve 4. The longitudinal section of the limiting groove 41 is in a cross shape. Four guiding blocks 43 are equidistantly installed on the inner side wall of the sleeve 4. One side wall surface of the guiding block 43 is inclined, and the guiding block 43 is aligned with the opening of the limiting groove 41. The arrangement of the guiding block 43 facilitates the alignment of the limiting groove 41 with the connecting rod 22, preventing the sleeve 4 from rotating under the action of external force, resulting in the subsequent connecting rod 22 being unable to be clamped inside the limiting groove 41. The side wall of the rotating rod 21 corresponds to the inner side wall of the sleeve 4. A connecting rod 22 is fixedly installed on the side wall of the rotating rod 21 close to the moving block 32. The longitudinal section of the connecting rod 22 is also in a cross shape. The connecting rod 22 is slidably installed on the inner side wall of the limiting groove 41. The connecting rod 22 corresponds to the limiting groove 41. A mirror body 6 is sleeved outside the sleeve 4. A central axis hole 61 is arranged inside the mirror body 6;

[0027] The mirror body 6 is sleeved on the sleeve 4. The second motor 3 is started. The second motor 3 drives the lead screw 31 to rotate. The rotation of the lead screw 31 drives the moving block 32 to move towards the direction of the first motor 2. During the movement of the moving block 32, the connecting rod 22 will enter the inside of the sleeve 4 and contact the guiding block 43, squeezing the guiding block 43, thereby driving the sleeve 4 to rotate, so that the connecting rod 22 is slidably installed on the inner side wall of the limiting groove 41 to fix the sleeve 4. Then the first motor 2 is started. The first motor 2 drives the rotating rod 21 to rotate. The rotation of the rotating rod 21 drives the connecting rod 22 to rotate, thereby driving the sleeve 4 relatively fixed to the connecting rod 22 to rotate, and further driving the mirror body 6 to rotate. The coating is started according to the designed coating process. After the coating is completed, the second motor 3 drives the lead screw 31 to rotate in the reverse direction to drive the sleeve 4 away from the connecting rod 22, and the mirror body 6 is taken off. The operation is convenient and fast.

[0028] It should be noted that the shapes of the connecting rod 22 and the limiting groove 41 can be set to polygonal shapes, but the shapes of the connecting rod 22 and the limiting groove 41 need to correspond to each other, and the number of the guiding blocks 43 corresponds to the openings of the limiting grooves 41.

[0029] As Figure 1 shown, in an embodiment, an installation frame 7 is arranged outside the first motor 2. Threaded holes are opened at both ends of the installation frame 7, and bolts 71 are spirally installed inside the threaded holes. The installation frame 7 and the base 1 are fixed by the bolts 71. A rubber pad is fixedly installed on the inner side wall of the installation frame 7. The rubber pad is provided to prevent the rotating rod 21 from being worn. A battery slot 12 is opened on the top wall surface of the base 1, and a battery body 8 is arranged inside the battery slot 12. The battery body 8 is electrically connected to the first motor 2 and the second motor 3 respectively.

[0030] As Figure 1 and Figure 3 shown, in an embodiment, two sliding grooves 42 are opened on the side wall of the sleeve 4. The two sliding grooves 42 correspond to each other. Two sliding blocks 62 are fixedly installed on the inner side wall of the central axis hole 61. The two sliding blocks 62 are respectively slidably installed on the inner side walls of the sliding grooves 42. The sliding blocks 62 and the sliding grooves 42 are provided to facilitate the limiting of the mirror body 6 and facilitate driving the mirror body 6 to rotate with the rotation of the sleeve 4. A baffle 5 is fixedly installed on the side wall of the sleeve 4, and a baffle 5 is also fixedly installed on the side wall of the rotating rod 21. The baffle 5 is provided to facilitate the limiting of the mirror body 6 and prevent the mirror body 6 from moving horizontally;

[0031] During the process of placing the mirror body 6 on the sleeve 4, the sliding block 62 is clamped on the inner side wall of the sliding groove 42, so that the mirror body 6 rotates together with the sleeve 4 when the sleeve 4 rotates, improving the rotation stability of the mirror body 6.

[0032] The specific working method is as follows: The mirror body 6 is sleeved on the sleeve 4, the second motor 3 is started, the second motor 3 drives the lead screw 31 to rotate, the lead screw 31 rotates to drive the moving block 32 to move towards the direction of the first motor 2. During the movement of the moving block 32, the connecting rod 22 will enter the inside of the sleeve 4, contact the guiding block 43, and squeeze the guiding block 43, thereby driving the sleeve 4 to rotate, so that the connecting rod 22 is slidably installed on the inner side wall of the limiting groove 41 to fix the sleeve 4. Then the first motor 2 is started, the first motor 2 drives the rotating rod 21 to rotate, the rotating rod 21 rotates to drive the connecting rod 22 to rotate, thereby driving the sleeve 4 relatively fixed to the connecting rod 22 to rotate, and further driving the mirror body 6 to rotate. The coating is started according to the designed coating process. After the coating is completed, the second motor 3 drives the lead screw 31 to rotate in the reverse direction to drive the sleeve 4 away from the connecting rod 22, and the mirror body 6 is taken off. The operation is convenient and fast.

Matters not covered by the present utility model belong to the common general knowledge of those skilled in the art.
