Description

Technical Field

[0001] The utility model relates to the technical field of label processing equipment, in particular to a label cutting device with positioning and counting functions. Background Art

[0002] A label is an additional identification card or brand added to an object. It is used to mark product targets and categories or contents, such as keywords for determining targets, which are tools for oneself and others to find and locate their targets. Most of the labels referred to in the printing industry are printed materials used to identify the relevant instructions of their own products, and most of them have self-adhesive on the back, but some are printed without glue, which can also be called labels, and labels with glue are commonly known as "self-adhesive labels".

[0003] Patent document CN220030384U discloses a label cutting device, including a base, a limit block, a limit cylinder and a knife seat, the top of the base is provided with four strip grooves, the inside of the strip grooves are all rotatably connected with screw rods, the limit blocks are all threadedly connected to the outside of the screw rods and the bottom is slidably connected to the bottom of the inner wall of the strip grooves, the limit cylinders are all rotatably connected to one side of the limit block, the top of the base and one side of the limit block are fixedly connected with a U-shaped plate, and the knife seat is slidably connected to the inside of the U-shaped plate. The utility model solves the problem that the driving disk rotates one circle to drive the label forward a certain distance, and then continues to rotate to drive the label further forward, and in the process of gradually advancing, the two sides of the label lack a limit mechanism, so that when cutting, the label is easily offset during the forward process, causing the label to deviate from the bottom of the knife seat, and then causing the knife seat to be unable to completely cut the label, and a part of the label is still connected after cutting, which is not conducive to practical application.

[0057] In this embodiment, it is further configured that the feeding assembly includes a supporting side plate 21, a feeding roller 22, a fixed block 23, a movable roller 24 and a movable ring 25, and the supporting side plate is connected to the frame bolts; the feeding roller is installed at the end of the supporting side plate, and the feeding roller is used to store the label roll; the fixed block is installed on one side of the supporting side plate; the movable roller is installed in the fixed block, and one end of the movable roller is connected to the output end of the driving motor. The driving motor is not drawn in the figure, and the movable roller can assist the conveying roller in pulling and conveying the label roll; the movable ring is connected to the supporting side plate through a soft rod 26, and the soft rod can be bent and has a certain elasticity. The setting of the movable ring can stretch the label roll, tighten the label roll, and prevent the label roll from sticking. When the label roll is conveyed at a too fast speed, the label roll is tightened, driving the soft rod to rise; when the label roll is conveyed at a too slow speed, the movable ring can prevent the label roll from falling to the ground and being contaminated, and the soft rod can be bent.
