The limit rod 3 212 penetrates the mounting platform 29 and is slidably connected to the mounting platform 29. By setting the limit rod 1 210, the limit rod 211 and the limit rod 3 212, the connecting block 24, the lifting platform 27 and the mounting platform 29 can be limited at the same time, respectively, to ensure that the connecting block 24 and the lifting platform 27 are in a fixed position. When the mounting platform 29 performs linear motion, the connecting block 24, the lifting platform 27 and the mounting platform 29 can be stably moved. The upper surface of the mounting seat 1 is rotatably connected with a rotating rod 1 213, and the upper surface of the mounting seat 1 is rotatably connected with a rotating rod 214.

There are two groups of conical blocks 48, which are symmetrically arranged with the center line of the connecting shaft 47 as the symmetry axis. The cross-sectional shape of the connecting shaft 47 is T-shaped. At the same time, two groups of springs are sleeved on the outer arc surface of the connecting shaft 47. The conical block 48 is fixed to one end of the spring, and the connecting shaft 47 is fixed to the other end of the spring. Through this arrangement, after the conical block 48 is squeezed by the slot 46, the conical block 48 will pass through the spring to clamp the conical block 48 into the slot 46, so that the cylinder 42 is connected to the arc gear 1 44 or the arc gear 2 45. After the cylinder 42 is rotated by the motor 41, it can drive the arc gear 1 44 or the arc gear 2 45 to rotate. At the same time, the cylinder 4 2 can drive the connecting shaft 47 to move linearly. When the connecting shaft 47 drives the conical block 48 to disengage from the slot 46, the inner surface of the slot 46 will squeeze the curved surface of the conical block 48, so that the conical block 48 will disengage from the slot 46. At the same time, the arc gear 1 44 is limited by the support rod 43, so that the arc gear 1 44 can only rotate on the support rod 43 to ensure the stability of the arc gear 1 44. The slot 46 and the conical block 48 are in the same horizontal plane as the slot 46. The inner surface of the slot 46 is slidably connected to the curved surface of the conical block 48. The rear surface of the rotating rod 1 213 is fixedly connected with the arc gear 3 49, and the arc gear 3 49 is meshed with the arc gear 2 45. The left surface of the rotating rod 2 214 is fixedly connected with the arc gear 4 10, the arc gear four 410 is meshed with the arc gear one 44, and through the arrangement of the arc gear one 44, the arc gear two 45, the arc gear three 49 and the arc gear four 410, through the cooperation of the cylinder 42, the connecting shaft 47 and the motor 41, the threaded rod one 23 and the threaded rod two 26 can be controlled to rotate through the cooperation of the single motor 41 and the cylinder 42. By using the arrangement of the motor 41, the cylinder 42 and the conical block 48, the overall price of the labeling machine is reduced.

The inner surface of the slide groove 53 is provided with a limiting groove 56 in a linear array, and the inner surface of the limiting groove 56 is slidably connected to the buckle 55. The U-shaped slide bar 54 can be stably moved up and down by limiting the position of the U-shaped slide bar 54 by the slide groove 53.

[0022] Working principle: when it is necessary to adjust the mounting platform 29, start the cylinder 42, and the output shaft of the cylinder 42 drives the connecting shaft 47 to move toward the inner side of the arc gear 1 44. After the conical block 48 is parallel to the slot 46, the conical block 48 is ejected into the slot 46 of the arc gear 1 44 by the spring of the connecting shaft 47, so that the cylinder 42 is connected to the arc gear 1 44, and the motor 41 is started to drive the cylinder 42 to rotate clockwise or counterclockwise. When the arc gear 1 44 rotates clockwise or counterclockwise, it meshes with the arc gear 410, drives the rotating rod 214 to rotate, and then drives the threaded rod 26 to rotate through the transmission belt, and drives the lifting platform 27 to adjust the position on the X-axis on the limit rod 211 through the threaded rod 26. When it is necessary to adjust the position of the Y-axis of the mounting platform 29, it can be achieved by directly manually rotating the threaded rod 3 28. When it is necessary to adjust the position of the Z-axis of the mounting platform 29, the cylinder 4 2 drives the connecting shaft 47 to continue upward, and the inner surface of the slot 46 squeezes the conical block 48 out of the slot 46 and continues to move upward. When the conical block 48 moves into the slot 46 of the arc gear 2 45, the conical block 48 is re-rejected into the arc gear 2 45 by the spring, and the arc gear 2 45 is driven to rotate by the motor 41. The arc gear 2 45 will drive the arc gear 3 49 to rotate, and the threaded rod 1 23 is driven to rotate by the rotating rod 1 213 to control the connecting block 24 to move linearly on the Z axis on the limiting rod 1 210. At the same time, when the installation platform 29 needs to be slightly rotated for installation, the buckle 55 is pulled out from the U-shaped slide bar 54, and the mounting seat 1 can be rotated at this time. During the rotation process, it will move on the L-shaped mounting rod 52 through the bracket 57. When the mounting seat 1 rotates, the buckle 55 is re-engaged in the limiting groove 56 to limit the rotating mounting seat 1.
