Description

Technical Field

[0001] The utility model relates to the field of label production, in particular to a double-layer label laminating structure based on a laminator. Background Art

[0002] At present, in the field of self-adhesive label production, the labels are generally single-layer self-adhesive labels. When manufacturers use them, they can directly tear the labels off the release paper and paste them on their own products for sale. Therefore, the laminating equipment for single-layer self-adhesive labels is relatively common, and such equipment is only equipped with one laminating mechanism. However, with the increasing market demand for label styles, types, functions, etc., the market for double-layer self-adhesive labels is becoming more and more open. Label manufacturers can choose a double-layer label laminator with a high price, which can directly obtain double-layer labels in one pass of the material, but the price of purchasing the equipment is relatively expensive, and it is difficult for small and medium-sized manufacturers to be equipped; or after passing through the laminator once, put it back into the laminator and pass through it again to laminate the second layer of labels. Although this method can save the cost of purchasing new equipment, the work efficiency is low, the production time is twice that of the single layer, and the machine needs to be stopped for feeding before re-feeding, which further increases the working hours and reduces the work efficiency. Content of the Utility Model

[0003] The purpose of this application is to provide a double-layer label laminating structure based on a laminator, aiming to solve the problems existing in the prior art.

[0014] The technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model. Apparently, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0015] As Figure 1 shown, a double-sided label laminating structure based on a laminating machine, the laminating structure includes a secondary unwinding roller 1 and a secondary laminating roller 2 arranged between the original machine laminating roller and the rewinding roller 13, and a water-cooling roller 3 is arranged in a rolling cooperation under the secondary laminating roller 2. The original laminating machine is provided with a primary unwinding roller 4 and a feeding roller 5 installed on the frame 17 at the upstream. A primary laminating roller 6 is arranged on the front side of the primary unwinding roller 4 and the feeding roller 5; a bottom roller 7 is arranged in a rolling cooperation under the primary laminating roller 6, and a single-sided adhesive label is made by pressing between the primary laminating roller 6 and the bottom roller 7.

[0016] In order to connect the original machine pressure roller and the secondary pressure roller, a conveying roller 8 is arranged between the bottom roller 7 and the water-cooled roller 3.

[0017] A paper guiding roller 9 is arranged in a staggered manner below the secondary unwinding roller 1, so that an obtuse angle vertex is formed between the paper guiding roller 9 and the secondary laminating roller 2. A separating knife 10 is arranged between the paper guiding roller 9 and the secondary laminating roller 2. The front end of the separating knife 10 is close to but does not touch the surface of the secondary laminating roller 2. The front end of the separating knife 10 is an acute angle. The upper side surface of the separating knife 10 connected to the acute angle is an inclined surface with the same angle as the label material conveying path. The lower side surface of the separating knife 10 connected to the acute angle is a horizontal plane for facilitating backward paper guiding. A recovery guiding roller 11 is arranged at the rear side of the separating knife 10, and a recovery roller 12 is arranged above the recovery guiding roller 11. The recovery guiding roller 11 forms an obtuse angle vertex between the recovery roller 12 and the separating knife 10.

[0018] Both the recovery roller 12 and the secondary unwinding roller 1 are installed on an extension frame 14 connected to the machine frame 17. Magnetic powder clutches are installed on the rotating shafts of the recovery roller 12 and the secondary unwinding roller 1. The rotation speed of the rollers is controlled by the magnetic powder clutches to feed the material according to the situation. Both the recovery roller 12 and the secondary unwinding roller 1 are air shaft. The magnetic powder clutch and the air inflation structure of the air shaft are both arranged in the extension frame 14.

[0019] There are two water-cooled rollers 3, and a conveying platform 15 is installed between the two water-cooled rollers 3; the front and rear end faces of the conveying platform 15 are concave arcs, and the radian matches the radian of the water-cooled roller 3. The material of the conveying platform 15 is metal. The two water-cooled rollers 3 can enhance the water-cooling effect, and the conveying platform 15 with good thermal conductivity can extend the cooling time to achieve rapid cooling of the label.

[0020] Both ends of the primary laminating roller 6 and the secondary laminating roller 2 are connected with lifting cylinders 16. The lifting of the laminating rollers is controlled by the lifting cylinders 16, so as to adjust the distance between the laminating rollers and the bottom roller 7.

[0021] The usage method of the present utility model is as Figure 2 shown. The base paper and the self-adhesive label are subjected to the first lamination on a laminating machine to obtain a label paper with a layer of self-adhesive label. Specifically, the feeding roller 5 conveys the base paper for feeding. A self-adhesive label roll is installed on the primary unwinding roller 4. The base paper and the self-adhesive label are laminated by the primary laminating roller 6 and the bottom roller 7 together, and the self-adhesive label is laminated onto the base paper.

[0022] Subsequently, the label paper with an adhesive label is conveyed by the conveying roller 8 to between the secondary laminating roller 2 and the water-cooling roller 3. During the process, an adhesive label roll is installed on the secondary unwinding roller 1. The adhesive label roll rotates clockwise to release the label. The label bypasses the paper guide roller 9 from below and then bypasses the separating knife 10 from above. At the front end of the separating knife 10, the adhesive label is separated from its self-adhesive release paper. The release paper bypasses the recovery guide roller 11 backward and is wound on the recovery roller 12. After the adhesive label is separated from the release paper, it is pressed by the secondary laminating roller 2 onto the top surface of the label paper with an adhesive label, forming a label paper with two layers of adhesive labels. The label paper with two layers of adhesive labels is cooled when passing through the water-cooling roller 3 and the conveying platform 15, and is wound up by the take-up roller 13.

[0023] For those skilled in the art, it is obvious that the present utility model is not limited to the details of the above-described exemplary embodiments, and without departing from the spirit or basic characteristics of the present utility model, the present utility model can be implemented in other specific forms. Therefore, from any point of view, the embodiments should be regarded as exemplary and non-restrictive. The scope of the present utility model is defined by the appended claims rather than the above description. Therefore, all changes falling within the meaning and scope of the equivalent elements of the claims are intended to be included in the present utility model. Any reference signs in the claims should not be construed as limiting the claims involved.
