Description

Technical Field

[0001] The utility model relates to the technical field of label trimming, in particular to an automatic guiding device for label trimming. Background Art

[0002] The automatic guide device used in the label trimming process is an important part of the label printing and cutting equipment. It can realize the precise and stable movement of the label during the cutting process and achieve accurate trimming. In the process of label trimming, the excess edge of the label is usually detached and the label is kept rolled up.

[0003] According to the Chinese patent publication number CN210795250U, "A device for trimming and winding rolls of rolled labels", it is mainly described that the distance between the cutters is adjusted by setting a cutter roller. The existing cutter rollers of the strip cutting machine are equipped with multiple cutters, which can rotate with the cutter roller to trim or cut the labels. However, the cutters on the existing cutter rollers are not easy to adjust the spacing, and the mounting rollers and winding rollers at both ends of the strip cutting machine need to be adjusted. The adjustment effect is often not good, which easily causes dimensional deviation in trimming or cutting. The cutter of the device is fixed to the cutter roller by bolts, which is very convenient to disassemble and adjust, and has multiple threaded fixing holes for installation. In combination with the mounting rollers and winding rollers at both ends, deviation in adjustment is avoided, and the quality of strip cutting and cutting is more in line with the standard. In this process, the machine will deviate under long-term trimming conditions, resulting in poor cutting accuracy.

[0004] Therefore, an automatic guiding device for label trimming is proposed to solve the problem that the machine will deviate under long-term trimming conditions during the process, resulting in poor cutting accuracy. Utility Model Content

[0017] Please refer to Figure 1-3An automatic guiding device for label trimming shown in the figure comprises a fixed frame 1, two fixed frames 1 are provided, a conveying mechanism 2 is provided on the fixed frame 1, the conveying mechanism 2 comprises a conveyor belt, the conveying mechanism 2 cooperates with a pressure roller 10, and can realize the movement of a label strip (a long strip composed of multiple labels), a fixed frame 3 is fixedly connected to the upper side of the fixed frame 1, two fixed sleeves 4 are sleeved on the fixed frame 3, a distance sensor 5 is fixedly connected to the bottom end of the fixed sleeve 4, and the distance sensor 5 is used to monitor the edge of the label strip, a driving motor is fixedly connected to one side of the fixed frame 3 and a rotating rod 7 is fixedly connected to the output end of the driving motor, a rotating plate 8 is fixedly connected to the rotating rod 7, and the driving motor drives the rotating rod 7 and the rotating plate 8 to rotate, so that the pressure roller 10 or the threaded roller 11 can contact the conveyor belt of the conveying mechanism 2 alone, and the two threaded rollers 11 can contact the conveyor belt of the conveying mechanism 2 separately. The thread directions of the roller 11 are opposite, and a transmission frame 9 is fixedly connected to one side of the rotating plate 8, and a driving motor is fixedly connected to one side of the transmission frame 9, and a pressure roller 10 is fixedly connected to the output end of the driving motor. A threaded roller 11 is rotatably connected between the two opposite rotating plates 8. A card slot 12 is provided on the fixed frame 1, and a first push rod 13 is fixedly connected in the card slot 12. The first push rod 13 and the second push rod 16 are both electric push rods. The output end of the first push rod 13 is fixedly connected to the lower mold 14, and the first push rod 13 drives the lower mold 14 to move. The two fixed frames 1 are located at the lower mold 14 and are fixedly connected to a fixed cover 15, and a second push rod 16 is fixedly connected in the fixed cover 15. The output end of the second push rod 16 is fixedly connected to the upper mold 17, and the second push rod 16 extends so that the upper mold 17 squeezes the lower mold 14, thereby realizing label trimming.

[0018] Among them, the lower mold 14 is in contact with the auxiliary roller 20, and the auxiliary roller 20 is connected to the bottom side of the connecting frame 19 through a rotating shaft. The connecting frame 19 is fixedly connected to the bottom end of the spring rod 18, and the spring rod 18 is fixedly connected to two sides away from each other in the fixed cover 15. By setting the auxiliary roller 20, the moving label can maintain contact with the lower mold 14.

[0019] The top roller 21 is rotatably connected to the lower mold 14 , and the grooves are located on two sides of the lower mold 14 that are far away from each other. By providing the top roller 21 , the friction between the label and the lower mold 14 can be reduced when the label moves.

[0020] A cushion block 22 is disposed in the card slot 12 , and the cushion block 22 contacts the bottom end of the lower die 14 . By disposing the cushion block 22 , the stability of the lower die 14 during die cutting can be increased.

[0022] Working principle: Place the label strip on the conveyor belt of the conveying mechanism 2. Under normal circumstances, the pressure roller 10 and the conveyor belt of the conveying mechanism 2 are in contact with the label strip, and the conveyor belt cooperates with the pressure roller 10 to move the label strip. When the four distance sensors 5 detect that the label strip is offset, the drive motor on the fixed frame 3 drives the rotating rod 7 to rotate, and makes the threaded roller 11 on one side of the rotating plate 8 contact the label strip and generate a pushing force, so that the label strip is accurately guided. At this time, the first push rod 13 and the second push rod 16 make the upper mold 17 and the lower mold 14 close together to cut the edge of the label strip. In this process, the top roller 21 reduces the friction between the label strip and the lower mold 14 when it moves. At the same time, the auxiliary roller 20 can make the label strip close to the lower mold 14 during the die-cutting process.
