Description

Technical Field

[0001] The utility model relates to a gluing device, in particular to a gluing device for a solventless laminator. Background Art

[0002] In the modern packaging and printing industries, the solventless lamination technology has been widely used. Compared with the traditional solvent-based lamination technology, the solventless lamination technology has the advantages of environmental protection, low cost, high safety, etc. However, in the process of solventless lamination, the gluing quality and efficiency directly affect the final quality of the composite film and the production efficiency. There are some technical defects in the existing gluing devices, mainly including the following points:

[0003] When the existing gluing device is gluing, the gluing is often uneven, resulting in defects such as bubbles and voids on the surface of the composite film, which affects the quality of the composite film. This is mainly due to the unreasonable design of the gluing brush or gluing roller, resulting in uneven distribution of the glue.

[0004] Since the gluing process requires an open environment, the existing gluing device is easily contaminated by dust and impurities, resulting in a decrease in the purity of the glue. In addition, the glue is easily volatilized in the open environment, increasing the use cost of the glue and the safety hazards in the production process.

[0005] The existing gluing device has a complex structure, which is inconvenient for operation and maintenance. When adding glue or cleaning the equipment, complex operations often need to be carried out after shutting down the machine, increasing the maintenance cost and downtime, and reducing the production efficiency.

[0006] Since there is a lack of effective guiding and fixing for the composite film during the conveying process, the composite film is prone to deviation or breakage, affecting the continuity of production and the product quality. Content of the Utility Model

[0007] To solve the above problems, the following technical solutions are proposed:

[0008] A gluing device for a solventless laminator, including a glue box. A driving roller is arranged in the glue box. A gluing device is arranged in the glue box below the driving roller. The gluing device includes a gluing roller and a gluing brush arranged on the gluing roller. When the gluing brush moves to the top of the gluing roller, the gluing brush can contact the bottom of the driving roller. An installation platform is arranged on the top of the glue box of the gluing brush. The installation platform is a horizontal platform arranged perpendicular to the side wall of the glue box. A guiding roller is arranged on each of the installation platforms on both sides of the glue box. The guiding roller is installed on the installation platform through an installation frame.

[0009] Furthermore, it further includes a dust-proof cover. The dust-proof cover is installed on the installation platform. An outlet and an inlet are respectively arranged on the dust-proof cover.

[0010] Furthermore, a coupling part is arranged on the installation platform. The dust-proof cover is sleeved on the coupling part, and the inner side wall of the dust-proof cover is coupled with the coupling part.

[0011] Further, there are two glue-brushing blocks arranged above the glue-applying roller. There is a gap in the diameters of the two glue-brushing blocks. Both ends of the glue-brushing blocks are fixedly connected to the dust-proof cover through mounting rods.

[0012] Further, the glue-brushing blocks are made of rubber.

[0013] Further, both the driving roller and the glue-applying roller are driven by motors.

[0014] Further, a glue-filling funnel is arranged on the side wall of the glue box.

[0015] The beneficial effects of the present utility model are as follows:

[0016] By arranging the glue-applying roller and the glue-brushing brush, when the glue-brushing brush moves to the top of the glue-applying roller, it can contact the bottom of the driving roller, ensuring that the glue is evenly coated on the composite film. The design of the two glue-brushing blocks makes the glue on the composite film more uniform, thereby improving the glue application quality of the composite film and reducing bubbles and unevenness.

[0017] The design of the dust-proof cover can effectively prevent dust and impurities from entering the glue application device, keep the glue pure, and extend the service life of the equipment. At the same time, the outlet and inlet designs of the dust-proof cover ensure a closed environment for the composite film during the glue application process, reduce the volatilization and waste of the glue, and improve economic benefits.

[0018] The arrangement of the mounting table and the guiding roller enables the composite film to pass through the glue application device smoothly, reducing the deviation and breakage of the composite film. The design of the glue-filling funnel facilitates the addition and replacement of the glue, simplifies the operation process, and reduces the maintenance time and cost.

[0019] The design of the glue-applying roller, the driving roller and the motor drive makes the entire glue application device simple in structure, easy to manufacture and maintain, and improves the reliability and durability of the equipment. Description of the Drawings

[0025] Solventless laminating machine glue application device, including glue box 1, a driving roller 3 is arranged in the glue box 1, a glue application device is arranged in the glue box 1 below the driving roller 3, the glue application device includes a glue application roller 21 and a glue application brush 22 arranged on the glue application roller 21. When the glue application brush 22 moves to the top of the glue application roller 21, the glue application brush 22 can contact the bottom of the driving roller 3. An installation platform 11 is arranged on the top of the glue box 1 of the glue application brush 22. The installation platform is a horizontal platform arranged perpendicular to the side wall of the glue box 1. A guiding roller 4 is arranged on each of the installation platforms 11 on both sides of the glue box 1. The guiding roller 4 is installed on the installation platform 11 through an installation frame 41. The glue is located at the bottom of the glue box 1, and the height of the glue is preferably not more than that of the glue application roller 21. The composite film first passes through one of the guiding rollers 4, then passes through the bottom of the driving roller 3, and then leaves the glue box 1 from the other guiding roller 4. The rotation of the glue application roller 21 enables the glue application brush 22 to apply glue to the composite film passing through the bottom of the driving roller 3. It also includes a dust-proof cover 6, the dust-proof cover 6 is installed on the installation platform 11, and an outlet 61 and an inlet 62 are respectively opened on the dust-proof cover 6. The composite film enters the glue box 1 through the inlet 62 and leaves the glue box 1 through the outlet 61. A coupling part 12 is arranged on the installation platform 11, the dust-proof cover 6 is sleeved on the coupling part 12, and the inner side wall of the dust-proof cover 6 is coupled with the coupling part 12. Two brush blocks 51 are arranged above the glue application roller 21, there is a gap in the diameters of the two brush blocks 51, and both ends of the brush blocks 51 are fixedly connected to the dust-proof cover 6 through installation rods 5. When the composite film passes between the two brush blocks 51, the brush blocks 51 can make the glue on the composite film more uniform. The brush blocks 51 are made of rubber material. Both the driving roller 3 and the glue application roller 21 are driven by motors. A glue application funnel 13 is arranged on the side wall of the glue box 1. Glue can be added to the glue box 1 through the glue application funnel 13.

[0026] The working principle of the present utility model is as follows:

[0027] The composite film enters the glue box 1 through the guiding rollers 4 installed on both sides of the glue box 1, first passes through one guiding roller 4, then passes through the bottom of the driving roller 3, and finally leaves the glue box 1 from the other guiding roller 4. The guiding rollers 4 ensure the smooth entry and exit of the composite film into and out of the glue application area. The glue application roller 21 is driven by a motor to rotate, driving the glue application brush 22 to move in the glue box 1. When the glue application brush 22 moves to the top of the glue application roller 21, the glue application brush 22 can contact the bottom of the driving roller 3, evenly coating the glue on the composite film. The rotation of the glue application roller 21 ensures the continuous supply and uniform distribution of the glue. The two brush blocks 51 arranged above the glue application roller 21 are fixedly connected to the dust-proof cover 6 through the installation rods 5, so that when the composite film passes between the two brush blocks 51, the brush blocks 51 can make the glue on the composite film more uniform. This design further improves the uniformity and quality of glue application.

[0028] The dust cover 6 is installed on the mounting table 11. The dust cover 6 is sleeved on the coupling part 12 through the coupling part 12, ensuring a tight connection between the inner side wall of the dust cover 6 and the coupling part 12. The design of the dust cover 6 effectively prevents dust and impurities from entering the gluing device, keeping the gluing environment clean.

[0029] When glue needs to be added, the operation can be carried out through the glue filling funnel 13 on the side wall of the glue box 1. The glue filling funnel 13 is designed at the top of the glue box 1, facilitating the filling and replacement of glue, ensuring the continuous operation of the equipment and the simplicity of operation.

[0030] The drive roller 3 and the gluing roller 21 are both driven by motors, ensuring the efficient operation of the gluing device. The precise control of the motors makes the gluing process more stable and reliable, improving the working efficiency of the equipment.
