Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of die-cutting processing, in particular to a die-cutting structure and a die-cutting machine for label webs. Background Art
[0002] A product label refers to the logo and sticker of a product, including text, patterns, etc. As a carrier for carrying product information, it is generally pasted on the product. Usually, labels are pasted on a tape at regular intervals and wound into a web for supply. A label is a composite material with a fabric made of paper, film or other materials, coated with an adhesive on the back and a silicone-coated release paper as the backing paper. It needs to go through processing procedures such as printing and die-cutting to become a finished label. Among them, the web includes a main body part and the backing paper. After the web goes through the die-cutting process, multiple spaced-apart labels and waste materials will be formed. It is necessary to peel or remove the die-cut waste materials adhered to the surface of the backing paper, otherwise it will affect the subsequent use of the label. With the development of labels, in order to facilitate the use of users, when die-cutting the web, a tear line will be die-cut on the backing paper part between two adjacent labels to facilitate the user to separate the two labels.
[0003] In the related art, when die-cutting waste materials and the backing paper of labels, the die-cutting tool for waste materials and the die-cutting tool for the tear line are both arranged above the web, so that the outer shape of the label product and the tear line of the backing paper are processed from the same surface. At this time, when die-cutting the tear line on the backing paper, the label needs to be die-cut together. At this time, the waste material part of the label will be pierced to die-cut the backing paper. Therefore, when separating the waste material from the backing paper, the waste material part may be pulled off, resulting in difficult waste discharge and thus low machine production efficiency.
[0004] Therefore, the prior art needs to be improved. Summary of the Utility Model
[0005] In order to make up for the deficiencies of the prior art, this application proposes a die-cutting structure and a die-cutting machine for label webs.
[0006] In a first aspect, the following technical solution is adopted for a die-cutting structure for label webs provided by the utility model:
[0007] A die-cutting structure for label webs includes an upper pressing table and a lower pressing table. The upper pressing table and the lower pressing table are respectively arranged on an external frame. The upper pressing table and the lower pressing table move towards each other. A product cutting knife is arranged on a side surface of the upper pressing table close to the lower pressing table. It is characterized in that: a backing paper cutting knife is arranged on a side surface of the lower pressing table close to the upper pressing table, and the backing paper cutting knife is used to form a tear line on the backing paper.
[0008] Preferably, positioning posts are provided on the lower pressing table, and positioning holes for the positioning posts to pass through are provided on the upper pressing table.
[0009] Preferably, a plurality of positioning posts are provided and are evenly distributed at the edge of the side of the lower pressing table close to the upper pressing table; the positioning holes are provided corresponding to the number and positions of the positioning posts.
[0010] Preferably, the side of the positioning post close to the upper pressing table is provided with a tip.
[0011] In a second aspect, the present utility model further provides an electronic atomization device adopting the following technical solution:
[0012] A die-cutting machine includes the above die-cutting structure.
[0013] In summary, the present application includes at least one of the following beneficial technical effects:
[0014] 1. When die-cutting the label web, the web will move in the form of a strip between the upper pressing table and the lower pressing table under the action of an external mechanism. At this time, under the action of the external frame, the upper pressing table and the lower pressing table will move towards each other, so that the product cutting knife on the upper pressing table cuts the main part of the web to form, and the base paper cutting knife on the lower pressing table directly die-cuts the base paper to complete one die-cutting of the web. In this design method, the punching of the web is carried out on the main part and the base paper respectively, so that the pressure of the tool die is dispersed and the operation process is more stable. At the same time, when die-cutting the tear line, the base paper is directly die-cut, and there is no need to die-cut the waste material, which can avoid the phenomenon that the waste material is not pulled off when the label is separated from the waste material. The waste discharge is relatively smooth, and there is no need to add additional auxiliary materials for waste discharge, saving costs.
[0015] 2. Due to the design of the positioning holes and the positioning posts, the upper pressing table can always move along the length direction of the positioning posts during the die-cutting process, so that the running stability of the upper pressing table is better, and it can be ensured as much as possible that the product cutting knife is always in the correct position during die-cutting, reducing the waste of the web.

[0019] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.
[0020] The embodiment of the present application discloses a die-cutting structure for label webs. Refer to Figure 1 , the die-cutting structure for label webs includes an upper pressing table 1 and a lower pressing table 2. Both the upper pressing table 1 and the lower pressing table 2 are rectangular plate-shaped and are made of hard metal. The upper pressing table 1 and the lower pressing table 2 are respectively connected to different positions of an external frame, and the upper pressing table 1 and the lower pressing table 2 are arranged at a relative interval. Moreover, under the action of the external frame, the upper pressing table 1 and the lower pressing table 2 can move towards each other. On the side surface of the upper pressing table 1 close to the lower pressing table 2, there is a product cutting knife 11. The product cutting knife 11 is used to cut the main part of the web into labels arranged at equal intervals. According to the different shapes of the labels, different-shaped product cutting knives 11 can be selected. In this embodiment, the shape of the product cutting knife 11 is a rectangular tube to stamp the labels into rectangular sizes. On the side surface of the lower pressing table 2 close to the upper pressing table 1, there is a waste paper cutting knife. The waste paper cutting knife acts on the base paper to cut a tear line at a predetermined position of the base paper.
[0021] Refer to Figure 1 , when die-cutting and stamping the label web, the web is fed between the upper pressing table 1 and the lower pressing table 2 in the form of a tape under the action of external equipment. At this time, the upper pressing table 1 moves downward by a predetermined distance so that the product cutting knife 11 separates the main part of the web into labels and waste. The lower pressing table 2 moves upward by a predetermined distance to cut a tear line in the base paper between two adjacent labels. In this design, the upper pressing table 1 punches the outer shape of the main part of the web from the front of the material, and the lower pressing table 2 punches the tear line from the back of the base paper, so that the two acting forces act on the upper and lower surfaces of the web respectively, which can disperse the pressure of the die, making the web more stable during the die-cutting and stamping operation. At the same time, when cutting the tear line, the base paper cutting knife 21 can directly die-cut the base paper without piercing the main part of the web, which can avoid the phenomenon that the waste is not pulled off when the label and the waste are separated, and the waste discharge is relatively smooth. There is no need to add additional auxiliary materials for waste discharge, saving costs.
[0022] Refer to Figure 1, in order to accurately position the upper platen 1 and ensure good stability, positioning posts 3 are provided on the lower platen 2. The positioning posts 3 are in the shape of cylindrical rods and are integrally provided on the lower platen 2. At the same time, positioning holes 12 are provided at the corresponding positions on the upper platen 1 for the positioning posts 3 to pass through. The part of the positioning post 3 close to the upper platen 1 is set to be a tip. In order to make the upper platen 1 operate more stably, multiple positioning posts 3 are provided, and the positioning holes 12 are provided corresponding to the positioning posts 3. The positioning posts 3 are evenly distributed on the four peripheral edges of the lower platen 2, so that during the die-cutting process, the upper platen 1 always moves along the length direction of the positioning posts 3, making the operation stability of the upper platen 1 better, and can ensure that the product cutting knife 11 is always in the correct position during die-cutting as much as possible, reducing the waste of the rolled material.
[0023] The present utility model also provides a die-cutting machine, including the above-mentioned die-cutting mechanism. The die-cutting machine of this embodiment also has the above beneficial effects and will not be elaborated one by one here.
[0024] The above are all the preferred embodiments of this application. The protection scope of this application is not limited accordingly. Therefore, all equivalent changes made according to the structure, shape, and principle of this application should be covered within the protection scope of this application.
