The clamping assembly is used to clamp and tension the fiberglass cloth, and the glue scraping assembly is used to scrape off the excess glue on the fiberglass cloth.

[0027] Specifically, a collection groove 103 is formed at the top of the base 1. By providing the collection groove 103 at the top of the base 1, the glue that drops during the glue scraping process can be collected, improving the subsequent cleaning effect. In addition, support pads 104 are fixedly arranged at the bottom of the base 1. There are two to ten groups of support pads 104 arranged evenly, preferably four groups, which can improve the stability of the base 1.

[0028] For the frame 101, it is fixedly arranged at the top of the base 1, and the frame 101 is approximately in an inverted "C" structure.

[0029] For the clamping assembly, it includes a first clamping seat 105, a second clamping seat 2, a clamping portion disposed on the first clamping seat 105 and the second clamping seat 2, and a driving portion for driving the second clamping seat 2 to approach or move away from the first clamping seat 105. Specifically, in this embodiment, the first clamping seat 105 is fixedly arranged at one end of the frame 101, the second clamping seat 2 is slidably arranged at the other end of the frame 101, the clamping portion is arranged in both the first clamping seat 105 and the second clamping seat 2, and a driving portion for driving the second clamping seat 2 to slide is arranged on the frame 101.

[0030] During use, the two ends of the fiberglass cloth can be respectively fixed on the first clamping seat 105 and the second clamping seat 2 through the clamping portion, and then the second clamping seat 2 is driven by the driving portion to move away from or close to the first clamping seat 105, so that the fiberglass cloth can be tensioned, and the tension degree of the fiberglass cloth can be conveniently adjusted, improving the use effect.

[0031] For the glue scraping assembly, it includes a mounting seat 4 and two scrapers 501 whose tops can slide towards each other in the mounting seat 4. Specifically, in this embodiment, the mounting seat 4 is slidably arranged at the top of the frame 101, the tops of the two scrapers 501 are both slidably arranged in the mounting seat 4, and an adjusting assembly for adjusting the distance between the two scrapers 501 is arranged on the mounting seat 4. Through the adjusting assembly, the two scrapers 501 can be driven to approach or move away from each other, which can not only scrape off the excess glue on both sides of the fiberglass cloth, but also adjust the thickness of the glue on both sides of the fiberglass cloth, improving the glue coating quality.

[0032] There are various ways to implement the above-mentioned driving portion. In this embodiment, refer to Figure 1 and Figure 2, the driving part can adopt a cylinder, an electric telescopic cylinder or a hydraulic cylinder, aiming to drive the second clamping seat 2 to slide. In this embodiment, the driving is designed as follows: a first screw rod 202 is rotatably arranged on the second clamping seat 2, and the first screw rod 202 has self-locking property. The first screw rod 202 is threadedly connected to the other end of the frame 101, and a first knob 203 is fixedly arranged at one end of the first screw rod 202 far away from the second clamping seat 2. When in use, by driving the first screw rod 202 to rotate through the first knob 203, the second clamping seat 2 can be driven to approach or move away from the first clamping seat 105, which is convenient for adjusting the tension of the glass fiber cloth and improving the use effect.

[0033] To guide the sliding second clamping seat 2, in this embodiment, referring to Figure 1 and Figure 2 , a guide rod 204 is fixedly arranged on the second clamping seat 2. Preferably, two groups of guide rods 204 are symmetrically arranged. One ends of the two groups of guide rods 204 far away from the second clamping seat 2 are both slidably connected to the side part of the frame 101. When in use, by fixedly arranging the guide rod 204 on the second clamping seat 2, the second clamping seat 2 can be ensured to slide smoothly.

[0034] Regarding the clamping part involved above, there are also various realizable ways. In this embodiment, referring to Figures 1 - 3 , the clamping part can adopt pneumatic clamping or hydraulic clamping. The clamping part is designed as two pairs of clamping plates 3, and one pair includes two groups. First limiting grooves 201 are respectively formed in the first clamping seat 105 and the second clamping seat 2. The two pairs of clamping plates 3 are respectively slidably connected to the corresponding first limiting grooves 201, and a first bidirectional screw rod 301 is rotatably arranged in both groups of first limiting grooves 201. The clamping plates 3 are respectively threadedly connected to the corresponding first bidirectional screw rod 301, and a second knob 302 is fixedly arranged at one end of the first bidirectional screw rod 301 extending out of the first limiting groove 201. When in use, by driving the first bidirectional screw rod 301 to rotate through the second knob 302, the two groups of clamping plates 3 can be driven to approach or move away from each other simultaneously, realizing the clamping effect on the glass fiber cloth.

In this embodiment, referring to Figure 1 , Figure 2 and Figure 4, the adjusting assembly can be adjusted by manually driving the squeegee 501 or by using pneumatic, hydraulic or other means of adjustment. In this embodiment, the adjusting assembly is designed as follows: two sets of symmetrically arranged fixed rods 5 are both slidably arranged on the mounting seat 4, and the two squeegees 501 are respectively fixedly arranged on the inner walls of the two fixed rods 5. A second limiting groove 401 is formed in the mounting seat 4, and a second bidirectional screw is rotatably arranged in the second limiting groove 401. One end of the two fixed rods 5 extending into the second limiting groove 401 is threadedly connected to the second bidirectional screw. A third knob 502 is fixedly arranged at one end of the second bidirectional screw extending out of the second limiting groove 401. When in use, by driving the second bidirectional screw to rotate through the third knob 502, the two squeegees 501 can be driven to approach or move away from each other simultaneously, which can not only scrape off the excess glue on the fiberglass cloth, but also adjust the thickness of the glue and improve the glue coating quality.

[0036] To achieve the glue scraping treatment for the entire fiberglass cloth, in this embodiment, referring to Figure 1 , Figure 2 and Figure 4 , a guiding groove 102 is formed at the top of the frame 101, the bottom of the mounting seat 4 is slidably arranged in the guiding groove 102, and a grip rod is rotatably arranged at the top of the mounting seat 4, which is convenient for pushing the mounting seat 4 to slide along the guiding groove 102. Moreover, the cross-section of the guiding groove 102 is in a T-shaped structure, which can ensure the reliable sliding of the mounting seat 4 and prevent the mounting seat 4 from shaking during glue scraping, thus affecting the glue coating quality.
