[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0029] This utility model provides a technical solution: such as Figure 1 As shown in this embodiment, an automatic packaging production line labeling device includes a mounting plate 100, a label conveying assembly 200, a label pressing assembly 300, a baffle 400, and a label quantity detection assembly 500. The label conveying assembly 200 consists of a feeding unit and a receiving unit, which are respectively located on the upper sides of the mounting plate 100. The label pressing assembly 300 is located in the middle of the upper part of the mounting plate 100. The baffle 400 is located on the side of the mounting plate 100. The baffle 400 and the label pressing assembly 300 are located on symmetrical sides of the conveyor belt. The label quantity detection assembly 500 is located on one side of the feeding unit and is used to detect the remaining amount of labels. When the remaining amount is insufficient, it reminds the staff.

[0030] like Figure 4 As shown, the feeding unit and the receiving unit have the same structure. The feeding unit includes a roller 201, a first U-shaped plate 202, and a positioning plate 203. The bottom of the roller 201 is rotatably mounted on the upper end of the mounting plate 100. The first U-shaped plate 202 is located on the side of the roller 201 and is fixedly connected to the side wall of the mounting plate 100. The upper end of the first U-shaped plate 202 is provided with a positioning plate 203. The positioning plate 203 has two fixing holes 204 and the upper end of the first U-shaped plate 202 has two mating holes 205. The two mating holes 205 correspond one-to-one with the two fixing holes 204. The diameter of the mating holes 205 is equal to the diameter of the fixing holes 204. The positioning plate 203 is also fixedly provided with a positioning sleeve 206, which is rotatably adapted to the upper end of the roller 201.

[0031] like Figure 3 As shown, the label quantity detection component 500 includes two movable rods 501, two guide sleeves 502, a reset switch 504, and an alarm 505. The two guide sleeves 502 are respectively fixedly installed on the side wall of the first U-shaped plate 202 away from the roller 201. The two movable rods 501 are respectively slidably engaged with the two guide sleeves 502. The two movable rods 501 also slide through the first U-shaped plate 202. The reset switch 504 and the alarm 505 are located at the upper end of one of the movable rods 501. The end of the reset switch 504 near the guide sleeve 502 is inclined. The reset switch 504 and the alarm 505 are electrically connected.

[0032] like Figure 3 As shown, the label quantity detection assembly 500 also includes a second U-shaped plate 506, a guide rod 507, a spring 508, and a third U-shaped plate 509. The second U-shaped plate 506 is disposed on the side of the movable rod 501 away from the roller 201. The second U-shaped plate 506 is fixedly connected to the two movable rods 501. The third U-shaped plate 509 is also fixedly installed on the side wall of the first U-shaped plate 202 away from the roller 201. The opening directions of the third U-shaped plate 509 and the second U-shaped plate 506 are opposite to each other. The guide rod 507 is fixedly connected to the middle of the side wall of the second U-shaped plate 506 away from the roller 201. The other end of the guide rod 507 slides through the third U-shaped plate 509. The spring 508 is fixedly connected between the third U-shaped plate 509 and the second U-shaped plate 506. The spring 508 is wound around the outer surface of the guide rod 507.

[0033] When spring 508 is compressed, the second U-shaped plate 506 moves towards the roller 201 under its pressure, causing the two movable rods 501 to move towards the roller 201. This causes the ends of the movable rods 501 to press against the upper and lower sides of the label roll. As the label roll is used, its thickness gradually decreases. Under the action of spring 508, the movable rods 501 continue to move towards the roller 201. When the thickness of the label roll becomes too small, the reset switch 504 enters the guide sleeve 502 and is thus opened by pressure. After the reset switch 504 is opened, the alarm 505 is activated, thus reminding the staff in advance that the label quantity is insufficient and needs to be replaced. When replacing the roller 201, a locking bar can be used to secure it between the second U-shaped plate 506 and the first U-shaped plate 202 (e.g., ...). Figure 3 As shown), this avoids the movable rod 501 affecting the replacement of the roller 201. The spring 508 needs to meet the following condition: when the alarm 505 is triggered, it is still in a compressed state. Its specific model can be selected according to the requirements, and there is no restriction here.

[0034] The distance between the two movable rods 501 is greater than the height of the label. This design ensures that the movable rods 501 will only contact the blank space on the label roll, preventing the movable rods 501 from directly contacting the label.

[0035] like Figure 6 As shown, the movable rod 501 has an installation groove 511 at one end near the roller 201. A roller 503 is installed in the installation groove 511. The upper and lower ends of the roller 503 are rotatably connected to the two inner walls of the installation groove 511 through a rotating shaft.

[0036] The roller 503 prevents the movable rod 501 from directly contacting the label roll, thus avoiding excessive resistance to the rotation of the label roll.

[0037] like Figure 3 As shown, a through groove 510 is provided in the middle of the first U-shaped plate 202.

[0038] The movement of the second U-shaped plate 506 can be prevented from being disturbed by the through slot 510.

[0039] like Figure 5 As shown, the feeding unit also includes a rotating seat 208, which is located below the roller 201. The rotating seat 208 is rotatably mounted inside the mounting plate 100. A circular groove is provided at the upper end of the rotating seat 208. The diameter of the circular groove is equal to the bottom diameter of the roller 201. A keyway is provided on the inner wall of the circular groove. A limit key is provided on the bottom side wall of the roller 201. The limit key and the keyway are compatible with each other. The bottom of the roller 201 is rotatably connected to the mounting plate 100 through the rotating seat 208.

[0040] During installation, the bottom of the roller 201 is inserted into the upper circular groove of the rotating seat 208. Through the matching of the keyway and the limit key, it can be ensured that the roller 201 and the rotating seat 208 will not rotate relative to each other, while ensuring that the bottom of the roller 201 rotates relative to the mounting plate 100. Then, the positioning sleeve 206 on the positioning plate 203 is fitted onto the upper end of the roller 201. At this time, the fixing hole 204 on the positioning plate 203 is aligned with the mating hole 205 on the first U-shaped plate 202. Through the cooperation of bolts and nuts, the positioning plate 203 and the first U-shaped plate 202 are fixed together, thereby completing the installation of the roller 201.

[0041] like Figure 1 As shown, a motor 207 is provided below the rotating seat 208 of the receiving unit. The motor 207 is fixedly installed on the bottom of the mounting plate 100, and the output shaft of the motor 207 is fixedly connected to the rotating seat 208.

[0042] The motor 207 drives the rotating seat 208 to rotate, which in turn drives the winding roller 201 of the receiving unit to rotate, thereby winding up the label roll.

[0043] like Figure 2 As shown, the label pressing assembly 300 includes a cylinder 301, a pressure plate 302, and a guide roller 303. The cylinder 301 is fixedly installed at the upper middle part of the mounting plate 100. The pressure plate 302 is fixedly installed at the end of the telescopic rod of the cylinder 301. Guide rollers 303 are respectively provided on both sides of the pressure plate 302. The guide rollers 303 are rotatably connected to the mounting plate 100.

[0044] The two ends of the label tape are located on two rollers 201 respectively. The label tape will span two guide rollers 303 and pressure plate 302. The two guide rollers 303 can guide the label tape so that the label between the two guide rollers 303 is parallel to the pressure plate 302, which makes it convenient for the pressure plate 302 to press the label. During operation, the conveyor belt is located between the baffle 400 and the label pressing assembly 300. When the workpiece on the conveyor belt moves between the pressure plate 302 and the baffle 400, the cylinder 301 will extend the telescopic rod so that the label is attached to the workpiece. The baffle 400 can support the other side of the workpiece.

[0045] The wiring diagrams for the motor 207, reset switch 504, alarm 505, conveyor belt, and cylinder 301 in this utility model are common knowledge in the field. Their working principles are known technologies. The appropriate model is selected according to actual use. Therefore, the control methods and wiring layouts for the motor 207, reset switch 504, alarm 505, conveyor belt, and cylinder 301 will not be explained in detail.

[0046] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
