Description

Technical field:

[0001] The invention belongs to the technical field of labels, and in particular relates to a device for producing self-adhesive labels for medical stickers. Background technology:

[0002] Since self-adhesive labels do not need to be applied with glue when pasting, which saves pasting time, they are conveniently and quickly used in various occasions. Self-adhesive labels are also called self-adhesive labels, instant stickers, and instant stickers. The self-adhesive labels commonly used now include a substrate layer, an adhesive layer, and a release paper layer. The release paper is bonded to the substrate by an adhesive, and then processed by printing, die-cutting, etc. to become a finished label. Another use of self-adhesive labels is to be used as medical patches. Existing medical patches generally include a substrate layer 1, a coating layer 2, an ointment layer 4, and a release paper 3. The adhesive is coated on the lower part of the substrate layer 1 to form the coating layer 2. The ointment layer 4 is pasted on the coating layer 2 in the middle of the lower side of the substrate layer 1. The release paper 3 is bonded to the coating layer 2 around the substrate layer 1, and the ointment layer is fastened between the substrate layer 1 and the release paper 3. In the production process of medical patches, the self-adhesive label is generally cut into the required shape and size, and then the release paper of the self-adhesive label is torn off, the ointment patch is placed on the substrate layer, and then the release paper is pasted. During the entire preparation process, workers are required to operate manually, the discharge amount and discharge position are difficult to control, the product quality is uneven, and with the gradual increase in labor costs, a production line is arranged with several to more than a dozen operators, which puts a heavy economic burden on the company. In addition, this medicine package is placed on the inner side of the adhesive layer, resulting in the area of ​​direct contact with the skin accounting for only one-third of the adhesive layer, which greatly reduces the firmness of the paste, especially when it is pasted on the joint position. With the movement of the joint and the influence of sweat, the medicine patch will inevitably fall off. Furthermore, the adhesive layer is a full-coated type, resulting in poor air permeability of the medicine package, especially in summer, and the comfort of use is extremely low. In order to solve the above problems, the inventor has designed a new type of medical patch, and at the same time provides a medical patch self-adhesive label required for the production of a medical patch, as well as a corresponding new type of medical patch production device and a medical patch self-adhesive label production device.
