Description

Technical Field

[0001] The utility model relates to the technical field of self-adhesive label cutting, in particular to a self-adhesive label cutting device. Background Art

[0002] Self-adhesive labels, also known as self-adhesive labels, are mainly used for liquid detergents and popular personal care products. Film materials are mainly used for mid-to-high-end daily chemical products. Popular personal care products and household liquid detergents account for a large proportion of the market, so corresponding paper materials are used more. Self-adhesive labels need to be cut using cutting equipment during the production process.

[0003] For example, Chinese patent (CN220807556U) discloses a self-adhesive label cutting machine, which includes a workbench, with grooves at both ends of the top of the workbench, a motor fixedly installed on one side of the workbench, and a rotating shaft of the motor passing through one side of the workbench and fixedly connected to a threaded rod. By arranging the groove, the motor, the threaded rod, the threaded cylinder, the guide assembly and the third plate body for coordinated use, when using this device to perform equidistant cutting of self-adhesive labels, after the self-adhesive label is placed on the top of the workbench, the two third plates can be moved by turning on the motor switch to achieve centering of the self-adhesive label, thereby ensuring equidistant cutting of the self-adhesive label, solving the problem in the prior art that when cutting self-adhesive labels, the middle position of the self-adhesive label to be cut needs to be manually placed directly under the cutter to achieve uniform cutting of the self-adhesive label, which is inconvenient and time-consuming to operate.

[0004] The above scheme still has the following technical deficiencies: the above scheme uses two cylinders to drive the pressure plate to press the self-adhesive label, and uses one cylinder to drive the cutting knife to cut the self-adhesive label. The above scheme uses a total of three cylinders, which has a high manufacturing cost and is more complicated to operate. At the same time, the above scheme is not convenient for adjusting the cutting position of the cutting knife. Based on this, a cutting device for self-adhesive labels is proposed.

[0040] The working principle of the above embodiment is:

[0041] When it is necessary to cut the self-adhesive label symmetrically, the self-adhesive label is placed on the base 1, and the second motor 202 is started. The output shaft of the second motor 202 rotates to drive the bidirectional screw 203 to rotate, and the bidirectional screw 203 drives the two alignment plates 205 to make relative movement.

After the cutting knife 508 and the limit assembly are adjusted to the specified position, the first motor 502 is turned off and the hydraulic cylinder 506 is started to cut the self-adhesive label.
