Description

Technical Field

[0001] The utility model relates to the field of glass fiber cloth processing, and more specifically, to a device for removing air bubbles after impregnating glass fiber cloth with glue. Background Art

[0002] Glass fiber cloth is an inorganic non-metallic material with very good performance, having advantages such as good insulation, high heat resistance, good corrosion resistance, and high mechanical strength. The appearance of glass fiber cloth products is smooth and beautiful, the weaving density is uniform and soft, and it can have good conformability even when laid on uneven surfaces.

[0003] After being woven, glass fiber cloth is generally supported in the warp and weft directions. Therefore, when impregnating with glue, due to the warp and weft directions, voids will appear at the grid-like nodes, and thus air bubbles are most likely to appear in the voids during impregnation. In the prior art, air bubbles are removed after semi-curing after impregnation. When removing air bubbles, generally the impregnated glass fiber cloth is directly passed between two pressure rollers, and the pressure rollers are heated to soften the glue and directly pressed to remove air bubbles. However, some air bubbles will remain inside the voids, so that the air in the air bubbles cannot be discharged during pressing and still remains in the glue coating of the glass fiber cloth, resulting in poor air bubble removal effect.

[0004] For the problems in the related art, no effective solution has been proposed yet. Summary of the Utility Model

[0005] In view of the problems in the related art, the present utility model proposes a device for removing air bubbles after impregnating glass fiber cloth with glue to overcome the above-mentioned technical problems existing in the prior related art.

[0006] The technical solution of the present utility model is realized as follows: A device for removing air bubbles after impregnating glass fiber cloth with glue includes a bottom plate, and anti-overflow plates are symmetrically installed on the sides of the bottom plate. Among them, a bubble elimination component is installed on one side between the anti-overflow plates, a winding component is installed on the other side between the anti-overflow plates, and a closing component is installed on the side of the middle of the anti-overflow plates.

[0007] Furthermore, the bubble elimination component includes a rotating roller, and a number of needle pricks are installed on the rotating roller. The needle pricks are arranged irregularly and densely on the rotating roller. A driving motor is installed outside one of the anti-overflow plates, and the output end of the driving motor is connected to the rotating roller.

[0008] Furthermore, the winding component includes a winding shaft, the winding shaft is installed on the side between the anti-overflow plates away from the rotating roller, and a winding roller is sleeved on the winding shaft.

[0009] Further, the closing assembly includes two rectangular grooves which are respectively formed in the two overflow prevention plates, and on the side of the overflow prevention plates near the rotating roller, an electric heating rod is slidably installed between the rectangular grooves, and a pressure roller is rotatably installed between the overflow prevention plates on the outer side of the electric heating rod.

[0010] Further, a support plate is installed on the outer side of the top end of the overflow prevention plate outside the rectangular groove, a support telescopic rod is installed at the bottom end of the support plate, a positioning ring is installed at the bottom end of the support telescopic rod, a downward pressure spring is installed between the cavity tube of the support telescopic rod and the positioning ring, and a bottom surface pressing assembly is installed between the winding roller and the pressure roller.

[0011] Further, the bottom surface pressing assembly includes a load-bearing rod which is installed between the overflow prevention plates below the side near the pressure roller, a bottom pressure ring is rotatably installed on the outer side of the load-bearing rod, the bottom pressure ring is in contact with the pressure roller, and the bottom pressure ring is made of a soft material.

[0012] Further, a direction-changing rod is installed above the load-bearing rod between the overflow prevention plates, a direction-changing sleeve is rotatably installed on the outer side of the direction-changing rod, and the phase-changing sleeve is made of a soft material.

[0013] The utility model provides a device for removing air bubbles after sizing of fiberglass cloth, and the beneficial effects are as follows:

[0014] 1. When removing air bubbles, the utility model can directly pierce the air bubbles on the fiberglass cloth, so that the air in the colloid is discharged in two times. The air pierced through in the colloid on the upper surface of the fiberglass cloth is discharged from top to bottom, and then the fiberglass cloth is redirected, so that the glue holes at the bottom of the colloid are in a V shape, and the internal air is discharged while being pressed by the bottom pressure ring, thereby completing the elimination of air bubbles. At the same time, the overflow prevention plate is used to prevent the softened colloid from being extruded to the outside of the bottom plate, so as to completely discharge the air bubbles inside the colloid and prevent the air from remaining in the colloid, resulting in incomplete elimination of air bubbles.

[0015] 2. After the fiberglass cloth is sized, when the colloid is in a semi-cured state, the fiberglass cloth is passed through the bottom of the needle of the rotating roller. At this time, the fiberglass cloth will be pierced by the needle, and then it will be further conveyed to the pressure roller, and pressed by the pressure roller. The colloid is softened by electric heating. At this time, the pierced colloid will be closed, and the internal air will be discharged from the holes pierced at the bottom side of the fiberglass cloth. Further, the fiberglass cloth will pass through the bottom of the pressure roller to between the bottom pressure ring and the pressure roller. Because the fiberglass cloth has an upward inclination angle, the holes pierced in the colloid at the bottom of the fiberglass cloth will be in a V shape, making the shape from inside to outside be narrow inside and wide outside. When passing through the bottom pressure ring, the glue holes will be closed by the bottom pressure ring, so that the internal air is extruded, and then softened again and adhered to the fiberglass cloth. Finally, the fiberglass cloth is conveyed to the winding shaft through the rotation of the direction-changing sleeve for winding. Brief Description of the Drawings

Detailed Embodiment

[0022] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the drawings in the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, rather than all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art belong to the scope of protection of the present invention.

[0023] As Figures 1-3 shown, a bubble removing device for fiberglass cloth after dipping in glue according to an embodiment of the present invention includes a bottom plate 1. Anti-overflow plates 2 are symmetrically installed on the sides of the bottom plate 1. Among them, a bubble elimination component 3 is installed on one side between the anti-overflow plates 2, and a winding component 4 is installed on the other side between the anti-overflow plates 2. Among them, a closing component 5 is installed on the side of the middle part of the anti-overflow plates 2.

[0024] Through the cooperation of the bubble elimination component 3 and the closing component 5 provided, when removing bubbles, the bubbles on the fiberglass cloth can be directly punctured, enabling the air in the colloid to be discharged in two times. The air punctured in the colloid on the upper surface of the fiberglass cloth is discharged from top to bottom. Subsequently, the fiberglass cloth is redirected, so that the glue holes at the bottom of the colloid are in a V shape, and while the internal air is discharged through the bottom pressing ring 5082, pressing is carried out, thereby completing the bubble elimination, and thus achieving the complete discharge of the bubbles inside the colloid, preventing air from existing in the colloid, which may lead to incomplete bubble elimination.

[0025] In addition, as Figures 1-3As shown, in one embodiment, the bubble eliminating component 3 includes a rotating roller 301, on which a number of needle prickers 302 are installed. The needle prickers 302 are arranged irregularly and densely on the rotating roller 301. A driving motor 303 is installed outside one of the overflow prevention plates 2, and the output end of the driving motor 303 is connected to the rotating roller 301. The winding component 4 includes a winding shaft 401, which is installed on one side of the overflow prevention plates 2 away from the rotating roller 301. A winding roller 402 is sleeved on the winding shaft 401. The closing component 5 includes two rectangular grooves 501, which are respectively opened on the two overflow prevention plates 2 and on the side of the overflow prevention plates 2 close to the rotating roller 301. An electric heating rod 502 is slidably installed between the rectangular grooves 501. A pressing roller 503 is rotatably installed outside the electric heating rod 502 between the overflow prevention plates 2. A support plate 504 is installed outside the top end of the overflow prevention plate 2 outside the rectangular groove 501. A support telescopic rod 505 is installed at the bottom end of the support plate 504, and a positioning ring 506 is installed at the bottom end of the support telescopic rod 505. A downward pressing spring 507 is installed between the cavity tube of the support telescopic rod 505 and the positioning ring 506. A bottom surface pressing component 508 is installed between the winding roller 402 and the pressing roller 503. The bottom surface pressing component 508 includes a bearing rod 5081, which is installed at the lower side of the edge of the overflow prevention plates 2 close to the pressing roller 503. A bottom pressing ring 5082 is rotatably installed outside the bearing rod 5081. The bottom pressing ring 5082 is in contact with the pressing roller 503, and the bottom pressing ring 5082 is made of a soft material. A deflecting rod 5083 is installed above the bearing rod 5081 between the overflow prevention plates 2. A deflecting sleeve 5084 is rotatably installed outside the deflecting rod 5083, and the deflecting sleeve is made of a soft material. After the glass fiber cloth is impregnated with glue, when the glue is in a semi-cured state, the glass fiber cloth is passed through the bottom of the needle prickers 302 of the rotating roller 301. At this time, the glass fiber cloth will be punctured by the needle prickers 302 and further conveyed to the pressing roller 503 for pressing. The glue is softened by electric heating. At this time, the punctured glue will close, and the internal air will be discharged from the holes punctured on the bottom side of the glass fiber cloth. Further, the glass fiber cloth will pass through the bottom of the pressing roller 503 to between the bottom pressing ring 5082 and the pressing roller 503. Because the glass fiber cloth has an upward inclination angle, the holes punctured in the glue at the bottom of the glass fiber cloth will be V-shaped, making the shape narrow inside and wide outside from the inside to the outside. When passing through the bottom pressing ring 5082, the glue holes will be closed by the bottom pressing ring 5082, so that the internal air is extruded, and thus is softened again and adhered to the glass fiber cloth. Finally, the glass fiber cloth is conveyed to the winding shaft 401 for winding through the rotation of the deflecting sleeve 5084; in addition, the bottom pressing ring 5082 and the deflecting sleeve can both be made of soft materials such as silica gel and rubber.

[0026] Based on the above solution, when the utility model is actually applied, its working principle or operation process is as follows: After the fiberglass cloth is impregnated with glue, when the glue is in a semi-cured state, the fiberglass cloth is passed through the bottom of the needle 302 of the rotating roller 301. At this time, the fiberglass cloth will be pierced by the needle 302 and further conveyed to the pressure roller 503. The pressure roller 503 is used for pressing. The glue is softened by electric heating. At this time, the pierced glue will close, and the internal air will be discharged from the holes pierced on the bottom side of the fiberglass cloth. Further, the fiberglass cloth will pass through the bottom of the pressure roller 503 to between the bottom pressure ring 5082 and the pressure roller 503. Because the fiberglass cloth has an upward inclination angle, the holes pierced in the glue at the bottom of the fiberglass cloth will be V-shaped, making the shape narrow inside and wide outside from the inside to the outside. When passing through the bottom pressure ring 5082, the glue holes will be closed by the bottom pressure ring 5082, so that the internal air is extruded, and then softened again and adhered to the fiberglass cloth. Finally, the fiberglass cloth is conveyed to the winding shaft 401 for winding through the rotation of the direction-changing sleeve 5084.

[0027] With the above solution of the utility model, the utility model can achieve directly piercing the bubbles on the fiberglass cloth when removing bubbles, so that the air in the glue is discharged in two times. The air pierced in the glue on the upper surface of the fiberglass cloth is discharged from top to bottom, and then the fiberglass cloth is deflected, so that the glue holes at the bottom of the glue are V-shaped, and the internal air is discharged while being pressed by the bottom pressure ring 5082, thus completing the bubble elimination, and achieving the complete discharge of the bubbles inside the glue, preventing the problem that the air in the glue causes incomplete bubble elimination.

[0028] The above are only the preferred embodiments of the utility model and are not intended to limit the utility model. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the utility model shall be included in the protection scope of the utility model.
