Description

Technical Field

[0001] The utility model relates to the technical field of adhesive backing machines, in particular to a adhesive backing machine which is convenient for adjusting the pressing thickness. Background Art

[0002] A gluing machine is an automated bonding device primarily used to bond adhesive materials to various substrates. Patent publication number CN217856984U discloses a gluing machine with adjustable adhesive amount and lamination thickness. This machine uses a motor to drive a screw to control a controlled scraper that moves closer to or away from a first pressure roller to adjust the adhesive thickness. This eliminates the drawbacks of traditional manual pulley control, which results in inaccurate adhesive thickness control and uneven movement of the two sides of the pressure roller, thus providing favorable conditions for subsequent processing steps. Furthermore, a second pressure roller located below can be moved to adjust the gap between it and the first pressure roller located above, thereby accommodating the gluing of sheets of varying thicknesses. However, this method creates a height difference between the second pressure roller located below and the sheet metal platform, and this height difference can change as adjustments are made, which can easily cause wrinkles in the substrate. Therefore, a gluing machine with easily adjustable lamination thickness is designed, which facilitates adjustment of both adhesive and lamination thicknesses while ensuring smooth introduction and removal of the substrate to prevent wrinkles.

DETAILED DESCRIPTION

[0020] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0021] Example:

[0022] See also Figure 1-4 The top of the frame 1 is rotatably connected to the lower pressing roller 2 by a rotating shaft, and the rotating shaft is rotatably connected to a U-shaped rotating frame 4 located above the lower pressing roller 2, and the U-shaped slide 5 is slidably matched on the U-shaped rotating frame 4, and the upper pressing roller 3 is rotatably connected on the U-shaped slide 5. A glue pressing driving part for driving the upper pressing roller 3 to rotate is provided on the U-shaped slide 5, and an angle adjustment mechanism for adjusting the inclination angle of the U-shaped rotating frame 4 is provided on the frame 1. A control scraping groove 9 is provided on one side of the upper pressing roller 3, which can be tilted toward the side of the upper pressing roller 3 and can be adjusted in angle. A glue outlet 10 is opened on the side of the control scraping groove 9 facing the upper pressing roller 3, and a fixed substrate introduction platform and a substrate outlet platform are respectively provided on both sides of the lower pressing roller 2.

[0023] Specifically, the U-shaped rotating frame 4 is provided with a lifting member for driving the U-shaped slide 5 to move up and down and slide. The lifting member includes a distance-adjusting drive cylinder 7 fixedly mounted on the U-shaped rotating frame 4. The output end of the distance-adjusting drive cylinder 7 is fixedly connected to the U-shaped slide 5. Through the lifting member, the U-shaped slide 5 is easily driven to move up and down on the U-shaped rotating frame 4. Starting the distance-adjusting drive cylinder 7 causes the output shaft of the distance-adjusting drive cylinder 7 to extend or shorten, thereby driving the U-shaped slide 5 to slide down or up on the U-shaped rotating frame 4.

[0024] Specifically, the angle adjustment mechanism includes an angle adjustment drive cylinder 8, the two ends of which are hinged to the frame 1 and the top of the U-shaped rotating frame 4 respectively, and the angle adjustment drive cylinder 8 is arranged in two groups and is arranged on both sides of the substrate lead-out platform. By extending or shortening the angle adjustment drive cylinder 8, the inclination angle of the U-shaped rotating frame 4 can be adjusted.

[0025] Specifically, the adhesive pressing drive component includes an adhesive motor 6 fixedly mounted on the U-shaped slide 5 , the output shaft of the adhesive motor 6 is fixedly connected to the upper pressing roller 3 , and starting the adhesive motor 6 can drive the upper pressing roller 3 to rotate.

[0026] Specifically, the frame 1 is fixedly connected to a support frame that supports the rotation of the quantity-controlled scraper 9, and the support frame is fixedly installed with an adjustment motor 11 that drives the rotation of the quantity-controlled scraper 9. The support frame is used to support the quantity-controlled scraper 9. Starting the adjustment motor 11 makes the output shaft of the adjustment motor 11 rotate clockwise or counterclockwise, thereby driving the quantity-controlled scraper 9 to rotate clockwise or counterclockwise.

[0027] Specifically, the substrate import platform and the substrate export platform include a loading platform 12 and a unloading platform 13 respectively, and the loading platform 12 and the unloading platform 13 are both rotatably and slidingly matched with the lower pressure roller 2 and fixedly connected to the frame 1, and the loading platform 12 is inclined upward toward the lower pressure roller 2 side, and the unloading platform 13 is inclined downward toward the side away from the lower pressure roller 2. The loading platform 12 and the unloading platform 13 are convenient for importing and exporting the substrates before and after the adhesive backing, respectively, while avoiding the accumulation of excess adhesive backing at the upper pressure roller 3, so that the adhesive backing flows to the side without adhesive backing along the inclination of the loading platform 12.

[0028] When in use, the substrate is input from the substrate inlet platform to between the lower pressing roller 2 and the upper pressing roller 3, the back glue pressing drive part is started, and the upper pressing roller 3 is driven to rotate, so that the back glue flowing out of the glue outlet 10 can flow to the upper pressing roller 3 and adhere to the top surface of the substrate through the rotation of the upper pressing roller 3. Then, under the action of the upper pressing roller 3 and the lower pressing roller 2, it is pressed and then exported through the substrate outlet platform. When the back glue thickness needs to be adjusted, the overall angle of the upper pressing roller 3 and the U-shaped rotating frame 4 can be directly adjusted through the angle adjustment mechanism, and then the distance from the glue outlet 10 can be adjusted. When the pressing thickness needs to be pressed, the position of the U-shaped slide 5 on the U-shaped rotating frame 4 can be adjusted to adjust the distance between the upper pressing roller 3 and the lower pressing roller 2. At the same time, the inclination angle of the control scraper groove 9 can be adjusted accordingly to redefine the distance between the glue outlet 10 and the upper pressing roller 3, that is, to redefine the back glue thickness.
