Those skilled in the art will understand the specific meanings of these terms in this utility model based on the specific circumstances.

[0029] See also Figure 1-2A labeling machine includes a conveyor belt 1, a label paper conveying device 2 is provided on the right side of the conveyor belt 1, a labeling roller 3 is rotatably connected to the left side of the label paper conveying device 2, a hydraulic press 4 is provided on the left side of the conveyor belt 1, a clamping assembly 5 is fixedly installed on the right side of the hydraulic press 4, bottles 6 are placed on the conveyor belt 1, and a light sensor switch 7 is provided at the front end of the conveyor belt 1.

[0030] See also Figure 3-6 The clamping assembly 5 includes a square plate 501, the rear end of the square plate 501 is fixed to the hydraulic press 4, a right clamp 502 is installed on the right side of the front end of the square plate 501, two fixed plates 503 and a connecting block 504 distributed up and down are installed on the left side of the front end of the square plate 501, a round rod 505 is fixedly installed between each fixed plate 503 and the right clamp 502, the two round rods 505 are jointly plugged with a left clamp 506, the rear end of the left clamp 506 is provided with two protrusions 507, a screw 508 is fixed on the left side, the screw 508 passes through the connecting block 504 and is threadedly connected to the adjusting wheel 510, each round rod 505 is sleeved with a spring 509, and the left clamp 506 and the right clamp 502 are both rotatably connected with a clamping roller 511.

[0031] It should be noted that the hydraulic press 4 is controlled by the light-sensing switch 7 to push the clamping assembly 5 to clamp the bottle 6. At the same time, during the clamping process, the adjustment wheel 510 can be rotated to expand or reduce the distance between the two clamping rollers 511 according to the different sizes of the bottles 6, so that the clamping of bottles 6 of different sizes is more stable.

[0032] In this embodiment, the conveyor belt 1 includes a conveyor belt and a conveyor frame. Several upright bottles 6 are placed on the conveyor belt. The bottles 6 move along with the conveyor belt. The conveyor belt 1 is provided with a groove 1 at the clamping component 5 and the label paper conveying device 2.

[0033] It should be noted that after the bottle 6 is clamped and labeled, the hydraulic press 4 returns to its initial state. At this time, the bottle 6 moves along with the conveyor belt. During the clamping and labeling process, there should be sliding friction between the bottom of the bottle 6 and the top of the conveyor belt. At the same time, the transport frame can effectively prevent the bottle 6 from tipping over due to unstable center of gravity during transportation.

[0034] In this embodiment, a motor is installed above the labeling roller 3 to drive it, and a light switch 7 is located at the front end of the labeling device. The light switch 7 controls the hydraulic press 4 and the motor on the labeling roller 3.

[0035] It should be noted that the motor above the labeling roller 3 drives it to rotate, and at the same time drives the bottle 6 to rotate, completing the labeling of the bottle 6. The motor is turned on and off once when the hydraulic press 4 reciprocates for one bottle 6.

[0036] In this embodiment, the bottle 6 is located between two clamping rollers 511 and one labeling roller 3, and is tightly connected with static friction at the connection point. The clamping roller 511 and the labeling roller 3 are both higher than the upper surface of the conveyor belt.

[0037] It should be noted that the bottle 6 can be effectively clamped by two clamping rollers 511 and one labeling roller 3. At the same time, when the labeling roller 3 drives the bottle 6 to rotate, the two clamping rollers 511 are also forced to rotate. The clamping roller 511 also has the function of flattening the label paper to prevent the label paper from having burrs.

[0038] In this embodiment, the spring 509 is sleeved on the round rod 505 and clamped between the right clamp 502 and the left clamp 506. The spring 509 is always in a stretched state, and the connector is located in the center of the left side of the front end of the square plate 501.

[0039] It should be noted that the provision of the spring 509 makes it more difficult for the adjusting wheel 510 to rotate by itself, thereby preventing the adjusting wheel 510 from rotating due to the vibration of the body during the operation of the device. At the same time, the addition of the spring 509 makes the sliding of the left clamp 506 more stable.

[0040] In this embodiment, two grooves 2 are formed in the front end of the square plate 501 and are distributed vertically. The grooves 2 are strip-shaped with a convex cross-section. The left clamp 506 slides in the grooves 2 of the square plate 501 through the protrusion 507 .

[0041] It should be noted that the round rod 505 and the protrusion 507 together ensure that the left clamp 506 is more accurate in the process of sliding left and right, and no clamping deviation will occur, which will lead to label distortion.

[0042] In this embodiment, an annular groove three is opened at the left end of the connecting block 504, and a circular through hole one is opened in the middle. The screw 508 passes through the through hole one and is threadedly connected to the adjusting wheel 510. The adjusting roller is rotated and clamped on the left end of the connector through the groove three.

[0043] It should be noted that when the adjusting wheel 510 is rotated, the adjusting wheel 510 remains in position, and the position of its internal thread changes, forcing the screw 508 to move left and right. The clamping distance is adjusted through this structure, which is not only convenient for adjustment but also makes the clamping more secure.

[0044] To sum up: when the light sensor switch 7 detects that the bottle 6 passes by, it sends an electrical signal, the hydraulic press 4 works, and the labeling roller 3 remains stationary. When the two clamping rollers 511 and the labeling roller 3 clamp the bottle 6, the light sensor switch 7 sends a signal again to drive the labeling roller 3 to rotate. When the labeling roller 3 rotates, it drives the bottle 6 to rotate. At the same time, the bottle 6 drives the two clamping rollers 511 to rotate. The clamping roller 511 has the function of clamping and flattening the labeling paper. For round bottles 6 with different radii, the screw 508 can be moved by rotating the adjusting wheel 510, and the screw 508 drives the left clamp 506 to move, so as to clamp and label bottles 6 with different diameters. At the same time, a slider and a round rod 505 are provided to jointly maintain the stability of the clamping slide, and the clamping distance can be manually adjusted, which is more convenient to use.

[0045] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
