Description

Technical Field

[0001] This utility model relates to the field of equipment technology, specifically to a glue applicator. Background Technology

[0002] Wall stickers typically consist of a printed film and a composite board layer. The designs on the stickers are printed on the printed film, such as... Figure 1 As shown, during manufacturing, a glue applicator with a glue spraying die 3 is generally used to bond the printed film 2 to the composite board layer 4. However, since the glue spraying part of the glue spraying die 3 is made of metal, and the pattern printed on the printed film 2 is the side that needs to be glued; in order to avoid the glue spraying die 3 scratching the pattern on the printed film 2, a protective layer is first bonded to the side of the printed film 2 with the pattern, and then the printed film 2 is bonded to the composite board layer 4 through the bonding mechanism 6. This method is not only complicated in terms of processing, but also time-consuming and material-intensive. Utility Model Content

[0003] The purpose of this invention is to provide a glue applicator to solve the problems mentioned in the background section.

[0004] To achieve the above objectives, the present invention provides the following technical solution: a glue coating machine, including a frame, a composite mechanism on the frame, a glue applicator roller on one side of the composite mechanism, and a glue spraying head on one side of the glue applicator roller; the frame is also provided with a pressure roller, and the movement of the pressure roller causes the printing film to contact the glue applicator roller, so as to transfer the glue on the glue applicator roller to the printing film.

[0005] As a preferred technical solution of this utility model: the frame is further provided with a support, and the support rotates on the frame to make the printing film material contact the glue roller.

[0006] As a preferred technical solution of this utility model: the frame is further provided with a driving component, and the driving component is connected to the bottom of the support to realize the contact between the pressure roller and the glue roller.

[0007] As a preferred technical solution of this utility model, the rotation direction of the glue-applying roller is completely opposite to the rotation direction of the pressure roller.

[0008] As a preferred technical solution of this utility model, the pressure roller is a rubber roller.

[0009] The beneficial effects of this utility model using the above technical solution are as follows: the die head sprays glue onto the glue-applying roller, and then the pressure roller contacts the glue-applying roller, thus effectively avoiding direct contact between the printed film and the die head. Furthermore, since the printing film can complete the glue application without direct contact with the die head, the printing film does not need to be pre-coated before glue application. In summary, since the printing film does not need to be pre-coated, the processing technology for wall sticker lamination can be simplified, reducing the processing cost of wall stickers; the fact that no coated film is needed when applying glue to the printed film also helps to increase the processing speed of wall stickers, thereby improving production efficiency; and the fact that no coated film is needed when applying glue to the printed film also reduces the use of coated film, further reducing waste generated during wall sticker production. Therefore, although this equipment is a simple optimization of the structure of an existing glue-applying machine, this simple structural optimization achieves many advantages, such as reducing waste generation in wall sticker production, simplifying the wall sticker processing technology, reducing costs, and improving efficiency.

[0014] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout.

In the description of this utility model, it should be understood that the terms "upper," "lower," "front," "upper surface," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as limiting this utility model.

[0015] Please see Figure 1-3The present invention provides an embodiment of a glue coating machine, comprising a frame 1, a composite mechanism 6 on the frame 1, a glue applicator roller 5 on one side of the composite mechanism 6, and a glue spraying head 3 on one side of the glue applicator roller 5; the frame 1 is also provided with a pressure roller 7, and the movement of the pressure roller 7 causes the printing film 2 to contact the glue applicator roller 5, so as to transfer the glue on the glue applicator roller 5 to the printing film 2.

[0016] In summary, the glue spraying head 3 sprays glue onto the glue application roller 5, and then the pressure roller 7 contacts the glue application roller 5. Therefore, direct contact between the printing film 2 and the glue spraying head 3 can be effectively avoided. At the same time, since the printing film 2 can complete the glue application without direct contact with the glue spraying head 3, the printing film 2 does not need to be pre-coated before applying glue.

[0017] In summary, since the printing film 2 does not require pre-coating, the processing technology for wall sticker lamination can be simplified, thereby reducing the processing cost of wall stickers; since the printing film 2 does not require the use of a pre-coated film during adhesive application, it is beneficial to increase the processing speed of wall stickers, thereby improving the production efficiency of wall stickers; since the printing film does not require the use of a pre-coated film during adhesive application, the use of pre-coated film can also be reduced, thereby reducing the generation of waste during the wall sticker production process.

[0018] Based on this, although the equipment is a simple optimization of the structure of the existing glue applicator, it can achieve many advantages such as reducing waste output in wall sticker production, simplifying the wall sticker processing technology, reducing costs and improving efficiency.

[0019] There are various ways in which the pressure roller 7 approaches the glue roller 5. For example, the frame 1 is also provided with a bracket 8, and the bracket 8 rotates on the frame 1 to make the printing film 2 contact the glue roller 5. Specifically, the middle part of the bracket 8 is connected to the frame 1 by a pin, so that the bracket 8 can rotate on the frame 1 along the pin to make the pressure roller 7 approach the glue roller 5. For example, a translation method can also be used, that is, the bracket 8 slides parallel to the bracket 8 to make the pressure roller 7 approach the glue roller 5.

[0020] Furthermore, since the frame 1 is also equipped with a driving component 9, which is connected to the bottom of the support 8, the pressure roller 7 and the glue-applying roller 5 can be brought into contact. Therefore, the driving component 9 can be used to move the support 8, thereby driving the pressure roller 7 closer to the glue-applying roller 5. For example, when the driving component 9 is a cylinder, the output shaft of the cylinder is connected to the bottom shaft pin of the support 8, and the middle part of the support 8 is rotatably connected to the frame 1 through a pin. Therefore, when the cylinder shaft of the cylinder extends, it can cause the pressure roller 7 to approach the glue-applying roller 5, and when the cylinder shaft shortens, it can cause the pressure roller 7 to separate from the glue-applying roller 5.

[0021] Since the adhesive is a high-viscosity coating, during use, the rotation direction of the glue-applying roller 5 is completely opposite to that of the pressure roller 7. By transferring the coating onto the substrate through friction, the efficiency of adhesive transfer can be improved.

[0022] In addition, since the pressure roller 7 is a rubber roller, the softness of the rubber roller is used to reduce the damage to the printing film 2 caused by the pressure roller 7 during rotation.

[0023] The embodiments of this utility model have been described in detail above with reference to the accompanying drawings, but this utility model is not limited to the described embodiments. For those skilled in the art, various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of this utility model, and these variations still fall within the protection scope of this utility model.
