Description

Technical Field

[0001] The utility model belongs to the technical field of glass fiber production for pipeline repair, and particularly relates to a glass fiber cloth glue coating device. Background Art

[0002] A glass fiber cloth is a fabric woven from glass fibers. In the prior art, the glass fiber cloth is generally conveyed by a driving roller shaft and enters a glue tank filled with resin glue. The glass fiber cloth with a uniformly covered glue surface is dried in an oven to form a semi-cured sheet. However, when the glass fiber cloth is completely immersed in the glue tank for dipping, it is difficult to accurately control the glue content of the glass fiber cloth after dipping, which is not conducive to the quality control of glass fiber production. At the same time, the glass fiber cloth coming out of the glue tank is easy to adhere to the glue liquid and drip down, resulting in a large amount of glue waste and affecting the working environment. Summary of the Utility Model

[0003] The utility model provides a glass fiber cloth glue coating device, which solves the technical problems such as difficult control of the dipping amount and large waste of the existing dipping device.

[0004] The utility model can be realized by the following technical solutions:

[0005] A glass fiber cloth glue coating device for glue liquid with relatively low viscosity includes a glass fiber cloth traction-transmitted by a winding and unwinding mechanism. The glass fiber cloth is obliquely downward conveyed. At the high end of its oblique position, a glue coating mechanism is horizontally arranged. At the low end of its oblique position, a driving winding roller is arranged, and an included angle capable of storing glue is formed between the two. The glue coating mechanism is used for uniformly spraying glue liquid along the width direction of the top surface of the glass fiber cloth. The winding and unwinding mechanism is used for unwinding, winding and conveying the glass fiber cloth, and making the bottom surface of the glass fiber cloth adhere to the glue liquid at the included angle at the winding position.

[0006] A recovery mechanism is arranged directly below the oblique position of the glass fiber cloth. The recovery mechanism is used for receiving and recovering the missed glue liquid.

[0007] Further, the glue coating mechanism includes a glue storage tank. A plurality of pipelines are uniformly and spacedly communicated with the bottom surface of the glue storage tank. The free end of each pipeline is communicated with a triangular nozzle, and they are arranged in sequence along the width direction of the glass fiber cloth. An inlet and an air inlet are arranged on the top surface of the glue storage tank. The air inlet is communicated with an air compressor. The air compressor is used for conveying air into the interior of the glue storage tank to apply pressure to the glue in the glue storage tank.

[0008] Further, these triangular nozzles are arranged in a row, closely attached to each other, and the total length formed is greater than the width of the glass fiber cloth. A guiding plate is arranged on the outside of each of the two outermost triangular nozzles. Each guiding plate is used for accumulating glue liquid and guiding it to flow down along the corresponding side of the glass fiber cloth.

[0009] Each of the triangular nozzles includes a triangular cavity. The apex angle of the triangular cavity communicates with the free end of the pipe and the valve. A plurality of through holes are evenly spaced on the bottom surface, and these through holes are arranged in a row along the width direction of the fiberglass cloth.

[0010] Furthermore, the winding and unwinding mechanism includes a driven unwinding roller, a plurality of transmission rollers, and a driving winding roller arranged along the conveying direction of the fiberglass cloth. The driving winding roller is arranged obliquely below the nearest transmission roller group, forming an obliquely downward conveying surface for the fiberglass cloth. The transmission roller group includes a plurality of transmission rollers arranged parallel and spaced up and down. They gradually approach the driving winding roller from top to bottom, and when the fiberglass cloth is conveyed to the driving winding roller through any one of them, the included angles formed are all different.

[0011] Furthermore, the recovery mechanism includes an adhesive receiving groove arranged directly below the area where the fiberglass cloth is obliquely downward conveyed to the driving winding roller. Upward bends are provided at the edge positions of the adhesive receiving groove, and a plurality of moving wheels are provided on its bottom surface.

[0012] The beneficial technical effects of the present utility model are as follows:

[0013] 1. The gluing mechanism is used to first evenly apply glue to the top surface of the fiberglass cloth, so that the glue can be evenly sprayed on the top surface of the fiberglass cloth and can flow into the corner for storage at the same time. Then, the winding and unwinding mechanism is used to make the bottom surface of the fiberglass cloth adhere to the glue from the corner, completing the double-sided impregnation of the fiberglass cloth. Compared with the one-time complete impregnation method of the glue tank, the gluing device of the present utility model can accurately control the glue spraying amount of the gluing mechanism and the corner size, thereby accurately controlling the glue content of the fiberglass cloth, greatly reducing glue waste, providing guarantee for the subsequent fiberglass production quality, and having stronger practicability.

[0014] 2. The gluing mechanism adopts a pressured spraying method, and the spraying amount is relatively controllable. At the same time, a guiding plate is added to collect the sprayed glue of the triangular nozzles at the edge positions, making them as much as possible meet the spraying requirements, increasing the glue content at the edge positions of the fiberglass cloth, and ensuring the uniform impregnation of the fiberglass cloth.

[0015] 3. Using the gluing device of the present utility model can achieve double-sided impregnation of the top surface first and then the bottom surface. The transmission rollers on the obliquely downward conveying surface of the fiberglass cloth will continuously contact the glue and need to be cleaned according to the actual situation, but most of them are on the bottom surface of the fiberglass cloth and will not contact the glue in a large area. Compared with the glue tank type one-time impregnation device, the disassembly and cleaning times will be greatly reduced, which can greatly reduce the workload of operators and improve work efficiency.

Specific embodiments

[0021] The following details the specific embodiments of the present utility model in conjunction with the accompanying drawings and preferred embodiments.

[0022] As Figures 1-3 shown, the present utility model provides a glass fiber cloth glue spraying device for glue with relatively low viscosity, such as being sprayed onto the glass fiber cloth and being able to flow by itself. It includes a glass fiber cloth conveyed by the rewinding and unwinding mechanism 1. The glass fiber cloth is conveyed obliquely downward. At the high end of its oblique position, a glue spraying mechanism 2 is horizontally arranged. At the low end of its oblique position, an active winding roller 11 is arranged, and an angle capable of storing glue is formed between the two. The glue spraying mechanism 2 is used to evenly spray glue along the width direction of the top surface of the glass fiber cloth. The rewinding and unwinding mechanism 1 is used for unwinding, winding, and conveying the glass fiber cloth, and making the bottom surface of the glass fiber cloth adhere to the glue at the angle during the winding position; A recycling mechanism 3 is arranged directly below the oblique position of the glass fiber cloth, and the recycling mechanism 3 is used to receive and recycle the leaked glue. Compared with the one-time double-sided impregnation in the prior art, the glue spraying device of the present utility model can first impregnate the top surface of the glass fiber cloth and then impregnate the bottom surface of the glass fiber cloth. The glue spraying amount on the top surface of the glass fiber cloth is controlled by the glue spraying mechanism, and the impregnation of the bottom surface of the glass fiber cloth is realized by using the glue stored at the angle. By adjusting the size of the angle, the impregnation amount of the bottom surface of the glass fiber cloth can be controlled, so as to accurately control the overall glue content of the glass fiber cloth, provide guarantee for the quality of glass fiber production, have stronger practicability, and be convenient for popularization and application.

[0023] Specifically as follows:

[0024] First, the winding and unwinding mechanism 1, the glue spraying mechanism 2, and the recycling mechanism 3 can all be arranged on the frame 4. The winding and unwinding mechanism 1 includes a driven unwinding roller 11, a plurality of driving rollers 12, and a driving winding roller 13 mounted on the frame. Both ends of these rollers can be mounted on the frame 4. Among them, the driving winding roller 13 is mounted obliquely below the nearest driving roller group, forming an obliquely downward conveying surface for the fiberglass cloth. The driving roller group includes a plurality of driving rollers arranged parallel and spaced apart vertically. They gradually approach the driving winding roller 13 from top to bottom. When the fiberglass cloth is conveyed to the driving winding roller 13 through any one of them, the formed included angles are all different. The ends of these driving rollers can be respectively mounted on the corresponding bent vertical plates 14, and the two bent vertical plates 14 are mounted on the frame 4, and the specific positions can be determined according to the requirements of the included angle size.

[0025] Since the glue spraying mechanism 2 is arranged at the high end of the oblique position, in addition to being impregnated into the top surface of the fiberglass cloth, the glue liquid sprayed out from it will also flow downward along the inclined surface until the included angle, forming an accumulation and storage. In this way, the wound fiberglass cloth can adhere to the glue liquid at the included angle, realizing the impregnation of the bottom surface of the fiberglass cloth.

[0026] To achieve the accumulation and storage, we can control the distance between the driving winding roller 13 and the nearest plurality of driving rollers 12, not too large, to avoid excessive penetration of the glue liquid into the fiberglass cloth or even leakage onto the recycling mechanism 3. We also need to control the glue spraying amount of the glue spraying mechanism 2, the conveying speed of the fiberglass cloth, the angle of the included angle, etc. They are all obtained through actual tests, with the aim of storing enough glue liquid to meet the impregnation requirements of the bottom surface of the fiberglass cloth.

[0027] In this way, according to the process requirements of fiberglass preparation, for different types of fiberglass corresponding to the glue content of the fiberglass cloth, different positions of the driving rollers can be used to convey the fiberglass cloth, so that the fiberglass cloth and the driving winding roller 13 form an included angle that meets the requirements, thereby enabling different degrees of sizing on the bottom surface of the fiberglass cloth. That is, with the help of the driving winding roller 13, the non-glue-sprayed bottom surface of the wound fiberglass cloth can adhere to the glue liquid at the included angle, realizing double-sided impregnation. We can also adjust the distance between the driving winding roller 13 and the oblique position of the fiberglass cloth, the winding force, etc. according to actual needs, so that the non-glue-sprayed bottom surface is further evenly sized.

[0028] The glue spraying mechanism 2 includes a glue storage tank 21 spanning above the fiberglass cloth. A plurality of pipes 22 are uniformly and spacedly connected to the bottom surface of the glue storage tank 21. The free end of each pipe 22 is connected to a triangular nozzle 23, and they are arranged in sequence along the width direction of the fiberglass cloth. These triangular nozzles 23 are arranged in a row, closely adjacent to each other. Each triangular nozzle 23 includes a triangular cavity. The apex angle of the triangular cavity is connected to the free end of the pipe 22, and a plurality of through holes are uniformly and spacedly arranged on the bottom surface. These through holes are also arranged in a row along the width direction of the fiberglass cloth. We can design the glue storage tank 21 to have a structure that is generally a quadrangular prism, with the lower part of its cross-section being a sharp angle shape. All the pipes 22 are arranged at the bottom end of the sharp angle. Of course, an adjustment valve can be provided on each pipe 22 to further control the glue flow rate. The through holes on the bottom surface of each triangular cavity are arranged, and the flow rate of the triangular nozzle 23 is set so that the glue sprayed onto the fiberglass cloth can cover the entire cloth surface by self-flowing and can also flow to the corners to gather.

[0029] To ensure that the glue can be smoothly sprayed from the nozzle onto the fiberglass cloth, we need to apply pressure to the glue surface inside the glue storage tank 21. Therefore, an air inlet 24 is provided on the top surface of the glue storage tank 21. The air inlet 24 is connected to an air compressor, which is used to convey air into the interior of the glue storage tank to apply pressure to the glue inside the glue storage tank. In this way, the pressurized gas generated by the air compressor acts on the glue surface, which is more conducive to pushing the glue to continuously spray out from the nozzle and evenly sprinkle onto the surface of the fiberglass cloth.

[0030] At the same time, since it is difficult for the applied pressure to evenly reach all positions on the glue surface, usually, the pressure at the central position of the glue storage tank 21 is relatively large, and the pressure at the edge position is relatively small. Therefore, the less glue is sprayed out from the triangular nozzles farther away from the central position, and even intermittent spraying may occur. Therefore, we also set the total length formed by the continuously arranged triangular nozzles to be greater than the width of the fiberglass cloth. A guiding plate 25 is provided on the outside of each of the two outermost triangular nozzles. Each guiding plate 25 is obliquely arranged, which can accumulate the glue and guide it to flow down along the corresponding side of the fiberglass cloth, thereby compensating for the glue spraying amount at the edge position to a certain extent to meet the process requirements.

[0031] In addition, a glue inlet 26 is provided on the top surface of the glue storage tank to facilitate adding glue to the glue storage tank.

[0032] Considering that glue leakage mostly occurs at the glue spraying and winding positions, the recycling mechanism 3 includes a glue receiving tank arranged directly below the area where the fiberglass cloth is obliquely conveyed downward to the active winding roller, as Figure 4 shown. Upward bends are provided at the edge positions of the glue receiving tank, and a plurality of moving wheels are provided on its bottom surface to facilitate moving and dumping or cleaning the glue. The upward bends can prevent glue from leaking sideways and better protect the working environment.

[0033] Although the specific embodiments of the present utility model have been described above, those skilled in the art should understand that these are only examples. Without departing from the principle and essence of the present utility model, various changes or modifications can be made to these embodiments. Therefore, the protection scope of the present utility model is defined by the appended claims.
