Description

Technical Field

[0001] This utility model relates to the technical field of decorative paper preparation apparatus, and in particular to a decorative paper preparation apparatus. Background Technology

[0002] Decorative paper undergoes a backing adhesive process during its preparation, where adhesive is applied to the back of the paper to make it waterproof, moisture-proof, and resistant to corrosion. Currently, the adhesive is applied through direct contact with the paper, which results in a bulky structure, inconvenient heat preservation of the adhesive, high energy consumption, and difficulty in cleaning.

[0003] This proposal is put forward in order to improve and optimize the above-mentioned problems or shortcomings. Utility Model Content

[0004] An apparatus for preparing decorative paper, used to apply adhesive to the back of the decorative paper so that it can form a protective film after light curing, thereby providing waterproof and moisture-proof protection for the decorative paper, comprising:

[0005] Two bearing seats and an aluminum alloy glue brush roller with both ends rotatably arranged relative to the bearing seats. The aluminum alloy glue brush roller has a cavity for holding glue and an overflow nozzle communicating with the cavity on the outer wall of the aluminum alloy glue brush roller. The glue is supplied into the aluminum alloy glue brush roller after being pressurized and forms uniform glue dots on the outer wall surface of the aluminum alloy glue brush roller through the overflow nozzle under pressure.

[0006] A sponge sleeve is fixed to the outside of the aluminum alloy glue roller. Its thickness exceeds that of the glue overflow nozzle. The sponge sleeve absorbs and homogenizes the glue squeezed out from the glue overflow nozzle. When the decorative paper presses over the part of the sponge sleeve, the glue is squeezed out and applied to the back of the decorative paper.

[0007] Preferably, an electric heating rod coaxial with the aluminum alloy glue brush roller is disposed inside the aluminum alloy glue brush roller to heat and keep the glue entering the inner cavity of the aluminum alloy glue brush roller at a certain temperature. A conductive slip ring is embedded through one end of the aluminum alloy glue brush roller, and a power supply is connected through the conductive slip ring to achieve stable power supply when the aluminum alloy glue brush roller rotates.

[0008] Preferably, a drive motor is provided at one end of the bearing housing, and a first gear is coaxially mounted on one end of the aluminum alloy brushing roller shaft and fixed by a flat key. A second gear is coaxially mounted on the shaft of the drive motor and fixed by a flat key. The first gear and the second gear mesh, so that the aluminum alloy brushing roller is driven to rotate by the drive motor.

[0009] Preferably, after the decorative paper is pressed onto the sponge sleeve, the sum of the compression of the sponge sleeve and the length of the overflow nozzle is less than the thickness of the sponge sleeve.

[0010] Preferably, a glue supply pipe is provided at one end of the aluminum alloy glue brush roller, wherein the glue supply pipe and the aluminum alloy glue brush roller are connected by a rotary sealing pipe joint, and the glue is pressed into the aluminum alloy glue brush roller through the glue supply pipe.

[0011] Preferably, the inner wall of the aluminum alloy glue brush roller is provided with a heat insulation coating, which effectively extends the heat preservation performance of the aluminum alloy glue brush roller.

[0012] The advantages and positive effects of this utility model are:

[0013] 1. The closed-loop glue supply effectively prevents dust from getting into the glue during the application process. The structure is simple, the glue is well heated and kept warm, making it easy to apply. The external sponge sleeve prevents glue from dripping and allows it to be better pressed onto the back of the decorative paper. Attached Figure Description
