Description

TECHNICAL FIELD

[0001] The utility model belongs to mica product technical field relates to a mica paper double -sided gluing device. BACKGROUND

[0002] Mica paper as widely used heat insulation, insulation, fireproof material, often according to the need and metal wire mesh, glass fiber cloth and other materials composite use, due to the scale structure of mica, in the composite process, often glue is coated on mica paper, then again with other materials paste composite, thus, it can effectively reinforce mica paper, also can utilize the surface microstructure of mica paper to realize the uniform adhesion of glue, the existing mica paper gluing generally utilizes the mode of indirect contact glue roller and mica paper, makes glue roller first contact glue and then remove mica paper, makes glue adhere to mica paper, often does not carry out glue scraping (avoid scratching mica paper) and glue supplementing (glue supplementing can cause glue layer to be too thick or uneven), this mode is simple, but the reinforcing effect of mica paper is weak, this is because the glue permeability of mica paper itself is poor, short contact with glue cannot make glue evenly spread on both sides of mica paper and reinforce mica paper, relatively, the uniformity of glue coating is also poor. SUMMARY

[0003] The utility model aims at the above-mentioned problem existing in prior art, provides a mica paper double -sided gluing device, and the technical problem to be solved by the utility model is how to improve the glue coating quality of mica paper.

[0004] The utility model discloses a mica paper double -sided gluing device, and the technical problem to be solved by the utility model is how to improve the glue coating quality of mica paper.

[0005] Further, the glue scraping roller is rotatably connected to the side wall of the glue box through the overrunning clutch.

[0006] After the mica paper is released from the unwinding roller, it passes through the cloth feeding roller, between the two cloth clamping rollers and each scraping roller in turn, and is finally pulled out. The mica paper between the two cloth clamping rollers is glued so that glue is attached to both sides. Under the action of the scraping roller, part of the glue is removed and flows downstream along the inclined surface of the mica paper between the adjacent scraping rollers and is recovered into the glue storage tank. After the action of multiple scraping rollers, not only can the attached glue be homogenized, but the glue can also be squeezed multiple times, which is beneficial to the penetration of the glue on the mica paper and improves the strength of the mica paper after the glue is cured. In addition, an overrunning clutch can be used to connect the scraping roller so that there is a speed difference between the mica paper and the scraping roller, thereby moderately increasing the scraping strength and extrusion strength of the scraping roller on the mica paper surface. BRIEF DESCRIPTION OF THE DRAWINGS

[0007] Figure 1 It is a structural diagram of the double-sided gluing device for mica paper.

[0008] In the figure, 1, unwinding roller; 2, glue box; 21, glue storage tank; 3, pull-out roller; 4, glue scraping roller; 5, cloth feeding roller; 6, cloth clamping roller. DETAILED DESCRIPTION

[0009] The following are specific embodiments of the present invention and the accompanying drawings to further describe the technical solution of the present invention, but the present invention is not limited to these embodiments.

[0010] like Figure 1 The double-sided gluing device for mica paper shown includes a discharge roller 1, a glue box 2 and a pull-out roller 3. The glue box 2 includes a glue storage tank 21 and several glue scraping rollers 4 located above the glue storage tank 21. A cloth feed roller 5 is provided on the side of the glue storage tank 21 close to the discharge roller 1. Two cloth clamping rollers 6 are provided between the cloth feed roller 5 and the lowermost glue scraping roller 4. The cloth clamping rollers 6 are located below the glue liquid level in the glue storage tank 21. The glue scraping rollers 4 are arranged in sequence from bottom to top, and the planes where adjacent glue coating rollers are located are inclined at an angle of 30 to 60 degrees to the horizontal plane; the glue scraping rollers 4 are rotatably connected to the side wall of the glue box 2 through an overrunning clutch.

[0011] After the mica paper is unwound by the unwinding roller 1, it passes through the cloth feeding roller 5, between the two cloth clamping rollers 6 and each scraping roller 4 in sequence, and is finally pulled out. The mica paper between the two cloth clamping rollers 6 is glued so that glue is attached to both sides. Under the action of the scraping roller 4, part of the glue is removed and flows downstream along the inclined surface of the mica paper between the adjacent scraping rollers 4 and is recovered into the glue storage tank 21. After the action of multiple scraping rollers 4, not only can the attached glue be homogenized, but the glue can also be squeezed multiple times, which is beneficial to the penetration of the glue on the mica paper and improves the strength of the mica paper after the glue is cured. In addition, an overrunning clutch can be used to connect the scraping roller 4 so that there is a speed difference between the mica paper and the scraping roller 4, thereby appropriately increasing the scraping strength and extrusion strength of the scraping roller 4 on the surface of the mica paper.

[0012] The specific embodiments described herein are merely illustrative of the spirit of the present application. Those skilled in the art of the present application can make various modifications or supplements to the described specific embodiments or replace them with similar ways, but will not deviate from the spirit of the present application or exceed the scope defined by the appended claims.
