The waste collection box 13 and the reject cylinder 12 are located on both sides of the conveying mechanism 3. The missing label detection camera 11 is used to detect whether the conveyed plastic bottles are missing labels. The adjustment mechanism 10 is used to install the missing label detection camera 11 and adjust its height, horizontal distance, and vertical distance.

[0028] In this embodiment, the adjustment mechanism 10 includes a height adjustment device, a lateral adjustment device, and a longitudinal adjustment device, wherein the lateral adjustment device is connected to the height adjustment device and the longitudinal adjustment device respectively, and the longitudinal adjustment device is connected to the missing label detection camera 11.

[0029] In this embodiment, the adjustment mechanism 10 further includes a support base 21, which is connected to the side of the conveying mechanism 3. The support base 21 is used to install the remaining adjustment devices. The height adjustment device includes a vertical slide bar 22, a vertical slider 23, a vertical screw 24, and a height adjustment knob 25. The vertical slide bars 22 are provided in two positions, opposite to each other and vertically arranged, and are connected and fixed to the support base 21 in any form. The vertical slider 23 is in the shape of a square and is sleeved on the vertical slide bar 22. The vertical screw 24 is threadedly connected to the vertical slide bar 23. The height adjustment knob 25 is fixed to the top of the vertical screw 24. By turning the height adjustment knob 25, i.e., turning the vertical screw 24, the vertical slide bar 23 is raised and lowered along the height direction of the vertical slide bar 22, thereby achieving height adjustment of the remaining structures connected to the vertical slider 23, i.e., the missing label detection camera 11. The lateral adjustment device includes a lateral slide bar 26, a lateral connecting plate 27, a lateral adjustment rod 28, and a lateral adjustment knob 29, wherein the lateral slide bar 26 is sleeved in the vertical slider 23 of the height adjustment device, and the end of the lateral slide bar 26 is connected and fixed to the longitudinal adjustment device in any form. There are two lateral slide bars 26, one above and one below, which are relatively parallel and arranged horizontally; the lateral connecting plates 27 are respectively fixed to the lateral slide bars 26 and connected with the lateral adjustment rod 28. There are two lateral connecting plates 27, which are symmetrically fixed at both ends of the lateral slide bar 26. The ends of the lateral slide bars 26 are connected by lateral connecting plates. The plate 27 is connected and fixed to the longitudinal adjustment device, and the transverse connecting plate 27 allows the transverse adjustment rod 28 to rotate inside it without generating a relative displacement in the transverse or longitudinal direction; the transverse adjustment rod 28 is threadedly connected to the middle position of the vertical slider 23; the transverse adjustment knob 29 is fixed to the end of the transverse adjustment rod 28 and is provided on the side of the transverse connecting plate 27; by turning the transverse adjustment knob 29, that is, turning the transverse adjustment rod 28, the transverse slide 26 is laterally extended and retracted relative to the vertical slider 23, thereby realizing the transverse distance adjustment of the remaining structures connected to the transverse slide 26, that is, the missing detection camera 11. The longitudinal adjustment device includes a fixing seat and a locking bolt. The fixing seat is composed of a vertically fixed fixing connecting plate 30 and a connecting plate 31. The fixing connecting plate 30 is provided with a plurality of threaded holes. The missing detection camera 11 is fixed in a threaded form, that is, it is fixed to the fixing connecting plate 30 with bolts; the connecting plate 31 is provided with a longitudinal adjustment hole, which is a waist-shaped hole. The locking bolt is passed through the waist-shaped hole to connect the connecting plate 31 to the transverse adjustment device (transverse connecting plate 27); the entire fixing seat moves relative to the transverse adjustment device along the length direction of the longitudinal adjustment hole, and after moving to the appropriate position, it is locked and fixed with a nut, etc., thereby realizing the longitudinal distance adjustment of the missing detection camera 11. The missing detection camera 11 in this device has an independent three-way adjustment function, which makes detection more convenient, more efficient, and more applicable.

[0030] In this embodiment, the drive motor 18 in the reduction motor is arranged vertically, and the upper portion of the drive motor 18 is connected to the reducer 19. The fixed plate 20 is a square plate structure, and the length of the fixed plate 20 is greater than that of the reducer 19. The encoder 8 is mounted on a mounting seat 32. The pulley group 9 and the mounting seat 32 are respectively mounted on the front and rear sides of the fixed plate 20. The pulley group 9 includes a main synchronous wheel, a synchronous belt, and a passive synchronous wheel. The main synchronous wheel is connected to the passive synchronous wheel through a synchronous belt. The main synchronous wheel is connected to the reducer 19, and the passive synchronous wheel is connected to the encoder 8 through a coupling. The mounting seat 32 is a columnar structure, which is fixed to the fixed plate 20 and can be fixed with bolts for easy assembly and disassembly. The coupling is arranged in the mounting seat 32. The mounting seat 32, or the encoder 8, is located on the side of the reducer 19, which can save space in front of the reducer 19 and facilitate the installation of the encoder 8. The encoder 8 in this device can know the operation status of the conveying mechanism 3, can assist in labeling, and ensure the speed and accuracy of labeling.

[0031] In this embodiment, the lifting mechanism 4 includes a lifting knob 33, a lifting block 34, a lifting screw 35, and a lifting guide rod 36. The lifting knob 33 is fixed to the lifting screw 35, the bottom of which is mounted on the chassis 1. The lifting block 34 is sleeved on the lifting guide rod 36 and is threadedly connected to the lifting screw 35. The label supply tray 5, the label dispensing mechanism 6, and the bottle-missing detection device 7 are mounted on the lifting block 34 via any frame structure. Turning the lifting knob 33, i.e., the lifting screw 35, causes the lifting block 34 to rise and fall along the height direction of the lifting screw 35 and the lifting guide rod 36, thereby causing the label supply tray 5, the label dispensing mechanism 6, and the bottle-missing detection device 7 to rise and fall. This facilitates adjustment of the labeling height, making it more convenient to use and more adaptable.

[0032] The working principle of this embodiment is: the conveying mechanism 3 is driven by the reduction motor to operate (at this time, the encoder 8 will upload the operating status to the human-machine interface control unit or other host computer in real time), so that the conveying mechanism 3 conveys the plastic-filled bottles from left to right. When the plastic-filled bottles pass through the labeling mechanism 6, the label supply plate 5 supplies the label and the labeling mechanism 6 takes out the label and sticks the label on the plastic-filled bottle. The labeled plastic-filled bottle continues to be conveyed to the right, and the missing label detection camera 11 detects whether the label is missing. The plastic-filled bottle that is detected as missing is then pushed out of the conveying mechanism 3 by the rejection cylinder 12, thus completing the entire conveying and labeling process.

[0033] The beneficial effects of this embodiment are: the entire conveying and labeling process of the labeling machine is more stable, detection is more convenient, efficiency is higher, applicability is stronger, the speed and accuracy of labeling are guaranteed, and it is easy to use.

[0034] Example 2

[0035] The difference between this embodiment and the first embodiment is that this labeling machine further includes a plurality of auxiliary brushes, which are arranged directly above the conveying mechanism 3 . The conveying mechanism 3 is provided with a plurality of auxiliary protrusions 37 , and the auxiliary brushes are used in conjunction with the auxiliary protrusions 37 .

[0036] In this embodiment, a plurality of mounting brackets 38 are provided on the side of the conveying mechanism 3, and the mounting brackets 38 are arbitrary rod frame structures; mounting rods 39 are installed on the mounting brackets 38, and mounting grooves 40 are provided in the mounting rods 39; the auxiliary brushes are fixedly installed in the mounting grooves 40, and the structural shapes of the two are adapted to each other.

[0037] In this embodiment, the auxiliary protrusion 37 is provided with a corresponding notch, the structural shape of which is adapted to the structural shape of the plastic-filled bottle. As the plastic-filled bottle is conveyed from left to right on the conveyor mechanism 3, when it passes the auxiliary brush, it is pushed backward (i.e., to the left). The resistance or thrust generated by the auxiliary brush pushes the plastic-filled bottle to the notch of the auxiliary protrusion 37, so that the plastic-filled bottle is closely adjacent to the auxiliary protrusion 37. This facilitates a closer arrangement of the plastic-filled bottles during conveyance, facilitating more stable conveying and labeling.

[0038] The beneficial effect of this embodiment is that by providing the auxiliary brushes and the auxiliary protrusions 37 , the entire conveying and labeling process of the labeling machine is more stable.

[0039] Example 3

[0040] The difference between this embodiment and the first embodiment is that the labeling machine further includes a telescopic mechanism, which is installed in the chassis 1 and connected to the foot 17 . The telescopic mechanism can drive the foot 17 to extend or retract into the chassis 1 .

[0041] In this embodiment, the telescopic mechanism can be implemented as lifting cylinders, distributed around the chassis 1, with the same number and arrangement as the feet 17. When the entire device needs to be operated, the telescopic mechanism drives the feet 17 out of the chassis 1, allowing the entire device to be supported and loaded by the feet 17, thus making the device more stable during operation. When the entire device needs to be transported or moved, the telescopic mechanism drives the feet 17 back into the chassis 1, allowing the entire device to be supported and loaded by the universal wheels 16. This allows the device to be transported and moved with only a small amount of force, making it more convenient and flexible to use.

[0042] The beneficial effect of this embodiment is that, by providing the telescopic mechanism, the labeling machine is more convenient to carry and move, and is more flexible and convenient to use.

[0043] The above description is merely a specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any changes, combinations, or substitutions that can be easily conceived by a person skilled in the art within the technical scope disclosed in the present invention should be included in the scope of protection of the present invention. Therefore, the scope of protection of the present invention should be based on the scope of protection of the claims.
