Description

Technical Field

[0001] The utility model relates to the technical field of coating devices, in particular to a coating device used for gluing thin glass fiber cloth. Background Art

[0002] Gluing and coating glass fiber cloth in preparation for the next process of cutting is an essential special process equipment in the glass fiber cloth production process, and its performance directly affects the quality and style of glass fiber cloth. The glue coating device is a set of devices that continuously transmit glue and evenly coat the glass fiber cloth surface. Through the rotation of the glue wheel, the outer wheel surface of the glue wheel contacts the glue in the glue groove, and then carries the glue to coat the glass fiber cloth surface moving at a uniform speed. The glass fiber cloth fiber yarn is infiltrated by the glue and then dried, bundled and solidified. After the next cutting, there will be no problem of silk falling off the cut surface.

[0003] The existing gluing method is a single glue-drawing coating wheel, which draws glue once and then applies it to the cloth surface. This method of gluing carries a large amount of glue that is difficult to control, and there is also a lot of glue condensed on the side of the outer ring of the coating wheel. Especially in the gluing of thin glass fiber cloth, it is easy to cause too much glue and too thick glue, and the glue penetrates and spreads outward on the thin cloth surface, so that the quality of the thin glass fiber cloth after gluing, such as thickness and uniformity, does not meet the standards.

[0004] Therefore, it is urgent to improve the design of a glue coating device that can reduce and easily control the amount of glue carried and has good uniformity, while reducing the problem of glue condensation on the side of the outer ring of the coating wheel, and improving the quality and stability of glue coating on thin glass fiber cloth. Utility Model Content

[0005] The purpose of the present invention is to solve at least one of the above technical deficiencies.

[0006] Therefore, one purpose of the utility model is to provide a coating device for gluing thin glass fiber cloth to solve the problems mentioned in the background technology and overcome the shortcomings of the prior art.

[0007] In order to achieve the above-mentioned purpose, an embodiment of one aspect of the utility model provides a coating device for gluing thin glass fiber cloth, comprising a mounting base plate, the top surface of the mounting base plate is fixedly installed with two symmetrically distributed first brackets by bolts, a first connecting shaft is rotatably connected between the two first brackets by bearings, a glue-drawing wheel is fixedly connected to the outer surface of the first connecting shaft, two symmetrically distributed second brackets are fixedly installed on the top surface of the mounting base plate by bolts, a second connecting shaft is rotatably connected between the second brackets by bearings, a coating wheel is fixedly connected to the outer surface of the second connecting shaft, a rubber ring is fixedly connected to the outer surface of the coating wheel, the glue-drawing wheel is located obliquely below the coating wheel, a glue groove is arranged between the two first brackets, the bottom of the glue groove is fixedly connected to the mounting base plate, and the bottom of the glue-drawing wheel is located inside the glue groove.

[0008] Preferably, any of the above schemes is that the outer sides of the first bracket and the second bracket are fixedly connected to the driving motor, and the first connecting shaft and the second connecting shaft are fixedly connected to the output end of the driving motor.

[0009] Preferably, any of the above schemes is that a glue inlet pipe and a glue outlet pipe are fixedly connected to the side of the glue groove, a valve is provided on one side of the glue inlet pipe and the glue outlet pipe, and the glue inlet pipe and the glue outlet pipe are connected to the glue storage tank.

[0010] Preferably, any of the above solutions is that the coating wheel is made of stainless steel, and the coating wheel is equal in length to the rubber introducing wheel.

[0011] Preferably, any of the above schemes is that the material of the rubber ring is silicone, the thickness of the rubber ring is 7 mm, and the hardness of the rubber ring is 75±3°.

[0012] Preferably, any of the above schemes is that the angle between the axis line of the coating wheel and the rubber introducing wheel and the plane is 45°, and the depth of the contact surface between the rubber ring and the rubber introducing wheel is 0.5 mm.

[0013] Compared with the prior art, the advantages and beneficial effects of the utility model are:

[0014] 1. The prior art is to apply glue directly to the glass fiber cloth after the glue wheel draws the glue once. The new device solution adds a coating wheel on the basis of the original glue drawing wheel. After the diameter of the glue drawing wheel is reduced and the thickness is reduced, the effect of transferring glue in the middle transition can be achieved. The driving motor can drive the glue drawing wheel to rotate. After the glue drawing wheel contacts the glue inside the glue groove, the outer wheel surface of the glue drawing wheel brings out the glue. By reducing the size and thickness of the glue drawing wheel, the amount of glue carried is reduced, which effectively meets the demand for subsequent coating on thin cloth.

[0015] 2. The added coating wheel is connected to the second bracket through a bearing, and can also be driven by a driving motor. The coating wheel does not need to be in direct contact with the glue groove. The outer wheel surface of the coating wheel contacts the outer wheel surface of the glue guide wheel, receiving the glue brought from the glue groove by the glue guide wheel, and then coating it on the fiberglass cloth surface, further reducing the amount of glue carried. At the same time, the coating wheel only carries the required amount of glue on the outer wheel surface, and there will be no glue condensation on the side of the outer ring, reducing the risk of excessive glue expansion when the coating wheel surface contacts the fiberglass cloth surface for glue coating.

[0016] 3. The outer ring of the coated wheel is wrapped with a layer of rubber ring. The original outer ring wheel surface is a steel plate, stainless steel material, which is relatively smooth and not easy to hang glue. The glue is easy to condense downwards under the action of gravity, resulting in uneven coating. The rubber ring is made of silicone. The rubber wheel surface increases the friction, which can better and more evenly hang the glue on the wheel surface, and when it is coated on the fiberglass cloth surface, it ensures the uniformity of the glue coating.
