Description

TECHNICAL FIELD

[0001] The utility model relates to the field of coating felt processing, especially relates to a gluing device for coating felt production. BACKGROUND

[0002] Glass fiber felt is a new type of glass non-woven reinforcing base material, which is widely used in pultrusion, molding, winding, hand lay-up, vacuum forming and other glass steel forming processes due to its isotropy, good flow conductivity, good washability, good moldability, high mechanical strength, easy bubble discharge and other advantages. The fiber reinforced plastic products reinforced by the base material are widely used in aerospace, chemical corrosion prevention, automobiles, boats, sports equipment, building materials, electronics, electrical appliances, entertainment appliances and other fields.

[0003] At present, the glass fiber coating felt in China is generally prepared by covering a layer of coating on the surface of the glass fiber thin felt. At present, the existing gluing method is that a inclined glue plate is arranged above the glass fiber felt at the gluing process, a glue scraping roller is arranged beside the glue plate, an upper glue pipeline is arranged on the glue plate, the upper glue pipeline has a glue outlet, the inlet of the upper glue pipeline is connected to the glue tank containing glue liquid through the feeding pipeline, the glue liquid in the glue tank is conveyed to the upper glue pipeline through the feeding pipeline, and then flows out from the glue outlet of the upper glue pipeline. The flowing out glue liquid flows along the glue plate to the glass fiber felt and is evenly wiped by the glue scraping roller to complete the gluing process.

[0004] In the above process, although the glue liquid on the glue plate is evenly wiped by the glue scraping roller, the gluing effect is not very good even after subsequent wiping, especially the thickness of the glue at the glue supply point is thicker than that at other positions. In addition, when the glue liquid flows in the glue tank and various pipelines, it is inevitable that the glue liquid will carry some solid particle impurities, and these solid particle impurities will flow to the glass fiber felt with the glue liquid, which will cause two situations in the subsequent processing. The first situation is that the solid particle impurities are scraped away by the glue scraping roller, but the glue at the position of the solid particle impurities will form a downward concave point. The second situation is that the solid particle impurities adhere to the glass fiber felt and enter the next process. Either situation will affect the high quality of the final coating felt.

[0011] Further, the filter is connected with the glue outlet connecting pipe through a quick connector, and a valve is arranged on the glue outlet connecting pipe.

[0017] To further illustrate the technical means and effects adopted by this utility model in order to achieve the intended utility model purpose, the following detailed description of the specific implementation methods, structure, features and effects of this utility model is provided in conjunction with the accompanying drawings and preferred embodiments.

[0018] like Figure 1 , Figure 2 The diagram shows a sizing device for producing coated felt. This sizing device is installed at the glass fiber felt conveyor belt and includes...

[0019] A rubber plate 1 is set above the fiberglass mat conveyor belt. The rubber plate 1 is inclined, and the inclination direction of the rubber plate 1 gradually slopes from top to bottom towards the conveying direction of the fiberglass mat conveyor belt. A glue-applying pipe 2 is installed on the rubber plate 1. The glue-applying pipe 2 is a hollow cylindrical pipe, and both sides of the glue-applying pipe 2 are sealed. The glue-applying pipe 2 extends along the long axis of the rubber plate 1. At the bottom of the glue-applying pipe 2, there are several glue outlets arranged in parallel. Each glue outlet is provided with a glue-applying connector 3.

[0020] A filter 4 is installed at each glue dispensing pipe 3. The filter 4 is connected to the glue dispensing pipe 3 via a quick connector 5. A valve 6 is also installed on the glue dispensing pipe 3. The use of quick connectors 5 to connect the filter 4 to the glue dispensing pipe 3, combined with the design of the valves 6 on each glue dispensing pipe 3, allows for quick online replacement of the filter 4 when there are too many impurities or the filter 4 is damaged, without affecting the continuous production of the coated felt.

[0021] The glue inlet of the glue application pipe 2 is connected to a glue tank through a glue supply hose. A glue supply pump is also installed in the glue tank or on the glue supply hose.

[0022] The glue-applying pipe 2 is mounted on the glue plate 1 on both sides via mounting brackets. Each mounting bracket includes a mounting plate, the top of which is fixed to the glue-applying pipe 2, and a slot 9 at the bottom of the mounting plate for inserting the glue plate. The mounting plate and slot 9 allow the glue-applying pipe 2 to be directly placed on the glue plate 1 without the need for fixing, facilitating both installation and subsequent disassembly.

[0023] The mounting plate is an L-shaped structure formed by the joint of the first plate body 7 and the second plate body 8, wherein the first plate body 7 is parallel to the long axis direction of the glue feeding pipe 2, and the first plate body 7 is directly welded with the glue feeding pipe 2; the second plate body 8 is perpendicular to the glue feeding pipe 2, and the slot 9 is arranged on the second plate body 8. For the structure of the mounting plate, the L-shaped structure formed by the joint of the first plate body 7 and the second plate body 8 can more stably support the glue feeding pipe 2 during erection, and can avoid the shaking of the glue feeding pipe 2.

[0024] In the gluing device, the glue liquid in the glue tank is pumped into the glue feeding pipe 2, and then filtered through the filters 4, and the filtered glue liquid flows out from the glue outlets of the glue feeding pipe 2, so that multi-point glue supply is realized. By arranging multiple glue outlets on the glue feeding pipe, multi-point glue supply is realized, which facilitates subsequent cooperation with the glue scraping roller and realizes uniform glue supply. When the filter 4 needs to be cleaned or replaced, the valve 6 corresponding to the filter 4 is directly manually closed, the filter 4 is removed, and then the new filter 4 is connected with the quick connector 5, which is very convenient and fast.

[0025] The above is only a preferred embodiment of the present application, and does not limit the present application in any form. Although the present application has been disclosed as a preferred embodiment, it is not intended to limit the present application. Any person skilled in the art can make some changes or modifications to the above disclosed technical content to obtain equivalent embodiments with equivalent changes, without departing from the technical solution of the present application. Any modification, equivalent change and modification of the above embodiments, which does not depart from the technical solution of the present application, is still within the scope of the present application.
