Description

Technical Field

[0001] This utility model relates to the field of impregnation technology, specifically to a fiberglass cloth impregnation device. Background Technology

[0002] Fiberglass cloth is a fabric woven from glass fibers. It has properties such as insulation, heat insulation, corrosion resistance, non-combustibility, high temperature resistance, and high strength. It is mainly used as an insulating material, a reinforcing material for fiberglass, a chemical filter cloth, a high-pressure steam insulation material, a fireproof product, a high-elasticity transmission belt, a building material, and a wall covering.

[0003] In existing equipment, after producing fiberglass cloth, it needs to be impregnated with glue to increase its strength and adhesion. After the fiberglass cloth is automatically impregnated with glue, a large amount of glue residue remains on the surface, resulting in glue waste that cannot be recycled. It also leads to uneven glue application on the fiberglass cloth, affecting the product quality.

[0004] For example, in application number CN202222635614.X, a glass fiber impregnation device is described. A single scraper can recover a small amount of glue, but as the scraper is used, glue tends to accumulate on it, making it impossible to completely recover the glue. This results in uneven coating of the glass fiber cloth on both sides, affecting the overall product quality. Utility Model Content

[0005] One object of this invention is to solve at least the aforementioned problems and / or defects, and to provide at least the advantages described below.

[0006] To achieve these objectives and other advantages according to the present invention, a fiberglass cloth impregnation device is provided, comprising: an upper half-box and a lower half-box detachably connected, wherein the upper half-box has symmetrically arranged inlet and outlet at both ends; an impregnation tank for impregnating the fiberglass cloth, which is disposed in the lower half-box, and further comprising:

[0007] Between the fabric inlet and the fabric outlet, there are sequentially arranged rollers: a first set of rollers, a second set of rollers, a third set of rollers, and a fourth set of rollers that are rotatably connected to the upper half of the box.

[0008] A trapezoidal scraper is installed between the third and fourth sets of rollers. One end of the trapezoidal scraper is slidably connected to the top of the upper half of the box, and the other end is attached to the front of the fiberglass cloth.

[0009] A gear-type scraper assembly is connected to the rotating shaft of the first set of drive motors and is positioned in the upper half of the box, directly opposite the trapezoidal scraper. The scraper edge of the gear-type scraper assembly is in contact with the back of the fiberglass cloth.

[0010] The glue storage tank is located within the lower half of the box and directly below the gear-type scraper assembly. Preferably, the structure of the first set of rollers includes:

[0011] Roller A1 is rotatably connected to the upper half of the box;

[0012] The telescopic assembly has its top end connected to the upper half of the box and its bottom end provided with a semi-circular telescopic shell. A roller A2 is rotatably connected inside the telescopic shell, and the fiberglass cloth is sandwiched between the roller A1 and the roller A2.

[0013] The structure of the fourth set of rollers is the same as that of the first set of rollers.

[0014] Preferably, the trapezoidal scraper has the following structure:

[0015] The scraper has a trapezoidal structure that is shorter in the front and longer in the back.

[0016] The T-shaped slide is located at the top of the upper half of the box body;

[0017] A slider assembly, one end of which is connected to the scraper, and the other end of which is provided with a T-shaped slider that is slidably connected to the T-shaped groove;

[0018] The telescopic rod is installed on the side of the upper half of the box and is fixedly connected to the slider assembly.

[0019] Preferably, the structure of the glue storage tank includes:

[0020] The glue storage tank is provided with a feed inlet and a second observation window on the outer wall of the lower half of the box. The height of the second observation window is equal to the top of the glue storage tank.

[0021] Similarly, the impregnation tank is equipped with an inlet and a first observation window.

[0022] Preferably, the structure of the second set of rollers includes:

[0023] A support frame is located at the top of the upper half of the box and is positioned directly opposite the impregnation tank. Rollers B1, B2 and B3 are rotatably mounted on the bottom of the support frame.

[0024] Preferably, the upper half of the box body has multiple sets of L-shaped buckles with through holes on its outer wall;

[0025] The lower half of the box body has a rectangular limiting block with a through hole positioned opposite to the L-shaped buckle on its outer wall. The L-shaped buckle and the rectangular limiting block are bolted together.

[0026] This utility model has at least the following beneficial effects:

[0027] This invention improves the overall quality of fiberglass cloth by installing a trapezoidal scraper and a gear-type scraper assembly before the cloth exit after the fiberglass cloth has been impregnated with adhesive. When the fiberglass cloth passes through, the trapezoidal scraper scrapes off the excess adhesive on the front side of the fiberglass cloth, while the gear-type scraper assembly scrapes off the excess adhesive on the back side of the fiberglass cloth. The adhesive falls into the adhesive storage tank directly below, and the recycled adhesive flows back into the impregnation tank. At the same time, a fourth set of rollers at the cloth exit smooths the remaining adhesive on both sides of the fiberglass cloth after the adhesive is applied, so that the adhesive is evenly applied to the fiberglass cloth and leaves from the cloth exit for the next operation.

[0028] The first set of rollers at the inlet can squeeze the fiberglass cloth to expel internal air, so that the glue can penetrate and fill the fiberglass cloth more fully after it enters the impregnation tank.

[0029] Other advantages, objectives and features of this invention will be partly apparent from the following description, and partly understood by those skilled in the art through study and practice of this invention. Attached Figure Description

[0039] The following is a detailed description of this novel experimental device with reference to the accompanying drawings:

[0040] Figure 1-4 This invention discloses a fiberglass cloth impregnation device, comprising: an upper half-box 13 and a lower half-box 14 detachably connected, wherein the upper half-box 13 has a cloth inlet 11 and a cloth outlet 12 symmetrically arranged at both ends; an impregnation tank 2 for impregnating fiberglass cloth 10, which is disposed within the lower half-box 14; and further comprising:

[0041] Between the fabric inlet 11 and the fabric outlet 12, there are sequentially arranged rollers 3, 4, 5 and 9 that are rotatably connected to the upper half of the box 13.

[0042] A trapezoidal scraper 6 is installed between the third set of rollers 4 and the fourth set of rollers 9. One end of the trapezoidal scraper 6 is slidably connected to the top of the upper half of the box 13, and the other end is attached to the front of the fiberglass cloth 10.

[0043] The gear-type scraper assembly 7 is connected to the rotating shaft of the first drive motor 71 and is positioned directly opposite the trapezoidal scraper 6. It is located inside the upper half of the box 13, and the scraper edge of the gear-type scraper assembly 7 is attached to the back of the fiberglass cloth 10.

[0044] The glue storage tank 8 is located inside the lower half of the box 14 and directly below the gear-shaped scraper assembly 7.

[0045] Working principle:

[0046] Before the housing is installed and fixed, the operator sequentially uses the first set of rollers 3, the second set of rollers 4, the third set of rollers 5 and the fourth set of rollers 9 to set the position of the fiberglass cloth 10 in the upper half of the housing 13, ensuring that the fiberglass cloth 10 can be moved and operated in the upper half of the housing 13. Then the upper half of the housing 13 is installed relative to the lower half of the housing 14 to achieve dust prevention of the device.

[0047] Before the fiberglass cloth 10 enters the box through the inlet 11 and is impregnated with glue, the air inside the fiberglass cloth 10 is squeezed by the first set of rollers 3 so that the glue can be fully filled after the fiberglass cloth 10 enters the impregnation tank 2. At this time, guided by the second set of rollers 4, the fiberglass cloth 10 begins the impregnation operation in the impregnation tank 2.

[0048] After the fiberglass cloth 10 has completed the glue impregnation process, it enters the third set of rollers 5 under the guidance of the second set of rollers 4. The trapezoidal scraper 6 moves back and forth on the front of the fiberglass cloth 10, so that the excess glue is scraped off by the two ends of the trapezoidal scraper 6 and falls into the glue storage tank 8 at the bottom for recycling. At the same time, the gear-type scraper group 7, driven by the first set of drive motors 71, scrapes off the excess glue on the back of the fiberglass cloth 10 with the edge of the scraper and falls into the glue storage tank 8 at the bottom for recycling. The gear-type scraper group 7 is designed to be continuously rotatable, which can prevent the glue from sticking to the device.

[0049] After the glue application is completed, the fiberglass cloth 10 enters the fourth set of rollers 9. The glue on both sides of the fiberglass cloth 10 is applied by the fourth set of rollers 9 to make the glue evenly applied. Finally, the fiberglass cloth 10 leaves from the cloth outlet 12, completing the glue impregnation.

[0050] This utility model features a detachable upper and lower box structure, which improves the sealing of the device and ensures that no dust enters during the entire impregnation process. This effectively prevents dust from sticking to the fiberglass cloth 10, causing unevenness on the surface and affecting the overall quality.

[0051] In the above scheme, the structure of the first set of rollers 3 includes:

[0052] Roller A1 is rotatably connected inside the upper half of the box 13;

[0053] The telescopic component 31 has its top end connected to the upper half box 13 and its bottom end provided with a semi-arc telescopic shell 32. A roller A2 is rotatably connected inside the telescopic shell 32, and the fiberglass cloth clamp 10 is held between the roller A1 and the roller A2.

[0054] The structure of the fourth set of rollers 9 is the same as that of the first set of rollers 3.

[0055] Working principle:

[0056] When the fiberglass cloth 10 passes through the first set of rollers 3 set in the upper half of the box 13, the telescopic component 31 (in actual use, a telescopic rod or telescopic bar connected to an external power source can be selected) adjusts its height downward so that the rollers A2 and A1 in the telescopic shell 32 are fully clamped and squeezed, thereby expelling the air remaining in the fiberglass cloth 10 and ensuring that the glue can be fully filled when it enters the impregnation tank 2.

[0057] Similarly, when the fiberglass cloth 10 passes through the fourth set of rollers 9, the telescopic components on it cause the two rollers to squeeze and cooperate, so that the glue residue on both sides of the fiberglass cloth 10 is evenly coated. After being evenly coated on both sides of the fiberglass cloth 10, it leaves from the outlet 12, effectively improving the overall quality of the product.

[0058] As described above, the structure of the trapezoidal scraper 6 includes:

[0059] The scraper 60 has a trapezoidal structure that is shorter at the front and longer at the back.

[0060] T-shaped chute 61 is located at the top of the upper half of the box 13;

[0061] The slider assembly 62 has one end connected to the scraper 60, and the other end is provided with a T-shaped slider 620 that is slidably connected to the T-shaped groove 61.

[0062] The telescopic rod 63 is installed on the side of the upper half of the box 13 and is fixedly connected to the slider assembly 62.

[0063] Working principle:

[0064] When the fiberglass cloth 10 is impregnated with glue and enters the third set of rollers 5, the telescopic rod 63 on the trapezoidal scraper 6 (in actual use, a telescopic rod or telescopic bar connected to an external power supply can be selected) drives the T-shaped slider 620 of the slider group 62 to slide horizontally left and right in the T-shaped groove 61. At this time, the excess glue on the surface of the fiberglass cloth 10 will fall into the glue storage tank 8 along the scraper 60, realizing the recycling of glue and avoiding waste.

[0065] The trapezoidal structure of the scraper 60, which is shorter at the front and longer at the back, can effectively allow excess glue to fall into the glue storage tank 8 along the edge of the scraper 60 as it moves left and right.

[0066] As described above, the structure of the glue storage tank 8 includes:

[0067] The glue storage tank 8 is provided with a feed inlet 81 and a second observation window 82 on the outer wall of the lower half of the box 14. The height of the second observation window 82 is equal to the uppermost part of the glue storage tank 8.

[0068] Similarly, the impregnation tank 2 is provided with an inlet 20 and an observation window 21.

[0069] Working principle:

[0070] During the glue dipping operation, the operator can observe the glue recycling status in the glue storage tank 8 through the second observation window 82 of the lower half of the box 14. When the visible height of the glue recycling is about to exceed the second observation window 82, the glue can be extracted for recycling or reuse.

[0071] Similarly, the operator can observe the usage of glue in the dipping tank 2 through the observation window 21 and replenish the glue in time through the filling port 20.

[0072] In actual use, to make it easier to determine the amount of glue used, scale lines can be set next to observation window 21 and observation window 82 on the outer wall of the lower half of the box 14.

[0073] As described above, the structure of the second set of rollers 4 includes:

[0074] The support frame 40 is located at the top of the upper half of the box 13 and is positioned directly opposite the impregnation tank 2. The bottom of the support frame 40 is rotatably equipped with rollers B1, B2 and B3. In actual use, when the fiberglass cloth 10 passes through the second set of rollers 4, the design of the three sets of rollers B1, B2 and B3 enables the fiberglass cloth 10 to be impregnated in an S-shape, further ensuring sufficient impregnation.

[0075] As described above, the outer wall of the upper box 13 is provided with multiple sets of L-shaped buckles 130 with through holes;

[0076] The lower half of the box 14 has a rectangular limiting block 140 with a through hole on its outer wall opposite to the L-shaped buckle. The L-shaped buckle 130 and the rectangular limiting block 140 are bolted together.

[0077] Working principle:

[0078] Before the impregnation process, the fiberglass cloth 10 passes through the upper half of the box 13 in sequence, passing through the first set of rollers 3, the second set of rollers 4, the third set of rollers 5, the fourth set of rollers 9, the trapezoidal scraper 6, and the gear-type scraper group 7. Then, the entire upper half of the box 13 is aligned with the lower half of the box 14 for installation. After the L-shaped buckle 130 is inserted into the rectangular limiting semi-enclosed shape, it is connected by bolts through the through hole to fix the upper half of the box 13 and the lower half of the box 14.

[0079] Although the embodiments of this utility model have been disclosed above, they are not limited to the applications listed in the specification and embodiments. They can be applied to various fields suitable for this utility model. For those skilled in the art, other modifications can be easily made. Therefore, without departing from the general concept defined by the claims and their equivalents, this utility model is not limited to the specific details and the illustrations shown and described herein.
