Technical Field

[0001] This invention relates to the field of coating equipment technology, specifically to a coating apparatus for processing glass fiber cloth. Background Technology

[0002] Due to its high strength, high temperature resistance, corrosion resistance, and excellent insulation properties, fiberglass cloth has been widely used in many fields such as electronics, building materials, aerospace, and new energy. In the processing of fiberglass cloth, the coating process is a key link to improve its performance and expand its application scenarios. For example, by coating the cloth surface with different types of coatings such as resin, flame retardant, and waterproofing agent, fiberglass cloth can acquire specific functional properties to meet the needs of different scenarios.

[0003] However, existing coating equipment has a long overall production line and occupies a large area, making it impossible to adjust according to actual needs; at the same time, the equipment can only use a single coating and has poor adaptability to coating switching. If different materials are coated, the same equipment is prone to mixed pollution. Summary of the Invention

The pair of cylinder seats are respectively symmetrically disposed on the rear side wall of the drying chamber and the front side wall of the cover plate, and the cylinder seats are close to the top. One end of the pair of electric push rods is movably connected to the cylinder seat, and the telescopic end of the electric push rod is movably connected to the swing plate. The telescopic extension of the electric push rod drives the swing plate to rotate. The two ends of the pair of first guide rollers are each provided with a roller shaft. The roller shafts at both ends of the pair of first guide rollers respectively movably pass through the adjustment grooves and are inserted into the first bearings at both ends of the swing plates.

[0008] Preferably, the coating structure includes a driving unit and a supporting unit; the driving unit is fixedly disposed on the base, the supporting unit is fixedly disposed on the driving unit, and the supporting unit can be translated and rotated 90 degrees by the driving unit.

[0009] Preferably, the drive unit includes an electric slide rail, a transition shaft, a gear, and a limiting frame; the electric slide rail is fixedly mounted on the upper left wall of the base and is located in front of the center line; the electric slide rail is provided with a sliding seat that moves left and right, and a second bearing is embedded in the middle of the sliding seat; one end of the transition shaft is fixedly inserted into the middle of the second bearing, and the transition shaft can rotate through the second bearing; the gear is fixedly mounted in the middle of the transition shaft and is located above the electric slide rail; one end of the limiting frame is fixedly mounted on the upper wall of the base and fits against the side wall of the electric slide rail; the other end of the limiting frame corresponds to the gear, and the side wall of the other end of the limiting frame is provided with teeth that can mesh with the gear; the other end of the limiting frame has an L-shaped groove that communicates with the side wall of the teeth.

[0014] The coating device for processing fiberglass cloth proposed in this invention has the following advantages: This invention enables the alternating use of two sets of coating structures. The coating structure utilizes the linear motion of an electric slide rail to drive the detachable support unit in linear motion. During this motion, the gears and the toothed portion of the limiting frame contact and rotate, achieving linkage between linear motion and rotation. This allows for the replacement of the two coating structures, especially for coating different materials on the same equipment, preventing mixing. The drying structure is designed to be freely spliced ​​according to the actual production line length and combined according to the drying speed. Furthermore, if the drying structure is used for conveying a single coating material, it can assist in adjusting the tension of the conveyed material. If it is used for different coating materials, the position of the internal second guide roller can be replaced, using one second guide roller to convey one coating material for differentiation, also preventing mixing, and eliminating the need for disassembly and replacement. In summary, this invention achieves the following effects:

[0015] 1. The coating end directly distinguishes different coatings through a pair of alternating coating structures, eliminating the need for repeated cleaning of a single coating tank and preventing cross-contamination from the source. The drying end distinguishes different coating materials by switching the position of the second guide roller. The same drying structure can be adapted to multiple materials without the need for additional drying components, further enhancing the anti-mixing effect. The replacement of coating structures and the switching of guide roller positions do not require complex disassembly, but can be completed by mechanical linkage or simple adjustment, adapting to the production needs of small batches and multiple specifications, and significantly reducing downtime for material changeover.

[0016] 2. The base can be freely spliced ​​through staggered first adapter claws, and the drying structure can be docked relative to each other through the second adapter claws. The processing path can be flexibly extended according to the actual length of the production line and the production scale. Multiple drying structures can be used in combination. The number of bearing units can be adjusted according to the coating drying requirements (such as fast-drying and slow-drying coatings) to ensure drying uniformity and avoid coating peeling caused by mismatched drying speeds. The expansion process only requires splicing existing components. There is no need to add new core drive or control modules, which reduces the equipment cost for enterprises to expand production scale. Only the existing unwinding and rewinding equipment needs to be set at both ends of the equipment.

[0017] 3. The electric push rod and swing plate combination of the drying structure can precisely adjust the position of the first guide roller through mechanical transmission, and adapt to the thickness of the glass fiber cloth and the amount of coating in real time, so as to avoid wrinkles, stretching deformation or loosening deviation during the conveying process, and ensure the uniformity of coating and the flatness of the cloth surface. The replacement of the first guide roller of the drying structure can be achieved without disassembling the entire drying box through the detachable cover plate and related structures of the swing plate, simplifying the operation process.

[0027] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0028] Please see Figures 1-8 This invention provides a technical solution: a coating device for processing glass fiber cloth, comprising a base 1, several drying structures 2, and a pair of coating structures. The base 1 is rectangular, and first adapter claws 9 are symmetrically arranged at both ends of the base 1. The first adapter claws 9 are used for relative splicing of the base 1, and the first adapter claws 9 are staggered. Several drying structures 2 are fixedly arranged on the upper right wall of the base 1, and the several drying structures 2 can be connected to each other. A pair of coating structures are symmetrically arranged on the upper left wall of the base 1, and the coating structures are located below the drying structures 2. The drying structures 2 are used for drying, guiding, and adjusting the tension of the coated glass fiber cloth during conveying. The drying structures 2 can also replace the guide rollers according to the coating requirements. The pair of coating structures can be used interchangeably to fit different coatings and prevent mixing.

[0029] As a preferred embodiment, the drying structure 2 further includes a support 21, a drying chamber 22, two pairs of telescopic columns 23, a cover plate 24, several heating rods 25, two pairs of second adapter claws 26, and an adjustment unit 27. One end of the support 21 is fixedly mounted on the upper wall of the base 1 and located on the center line. The drying chamber 22 is a box without left, right, or front side walls, and has a concave structure. Telescopic openings are symmetrically arranged at both the upper and lower ends of the front side of the drying chamber 22. The drying chamber 22 is fixedly mounted on the other end of the support 21. Arc-shaped adjustment grooves 5 are symmetrically arranged in the middle of the rear side wall of the drying chamber 22. One end of each pair of telescopic columns 23 is movably inserted into the telescopic opening. The cover plate 24 is detachably fastened to the front side of the drying chamber 22, and the cover plate 24 is connected to the telescopic columns 23. The cover plate 24 is fixed to the drying chamber 22 with bolts. The middle of the cover plate 24 is provided with an adjustment groove 5 corresponding to the rear side wall of the drying chamber 22. One end of several electric heating rods 25 is fixedly fixed on the rear side wall of the drying chamber 22 at equal intervals, and the electric heating rods 25 are located above the adjustment groove 5. Two pairs of second adapter claws 26 are symmetrically arranged at the four corners of the upper wall of the drying chamber 22. The switching unit 27 is movably arranged on the cover plate 24. The drying chamber 22 is supported at a certain height by the bracket 21. The drying chamber 22 carries the cover plate 24 and the electric heating rods 25. The electric heating rods 25 can dry the material passing through the drying chamber 22. The second adapter claws 26 can splice the drying chamber 22. The switching unit 27 can adjust the tension of the conveyor or change the first guide roller 274 as needed.

[0030] More specifically, the coated fiberglass cloth passing through the drying chamber 22 is dried evenly by heating the electric heating rod 25; multiple drying structures 2 are connected relative to each other by the second adapter claw 26 on the upper wall of the drying chamber 22 to adapt to different production line lengths; an installation base is provided for the switching unit 27, and the guide and tension are adjusted by the adjustment groove 5 in conjunction with the switching unit 27; the cover plate 24 is designed to be detachable, which facilitates the maintenance of internal components and the replacement of guide rollers.

[0031] As a preferred embodiment, the switching unit 27 further includes a pair of swing plates 271, a pair of cylinder seats 272, a pair of electric push rods 273, and a pair of first guide rollers 274. The middle portions of the swing plates 271 are respectively movably disposed in the middle of the rear side wall of the drying oven 22 and the middle of the front side wall of the cover plate 24, with both ends of the swing plates 271 corresponding to the adjusting grooves 5. The movable connecting part in the middle of the swing plates 271 is located at the center of the adjusting grooves 5. First bearings 7 are embedded at both ends of the swing plates 271. The pair of cylinder seats 272 are symmetrically disposed on the rear side wall of the drying oven 22 and the front side wall of the cover plate 24, with the cylinder seats 272 near the top. One end of the electric push rod 273 is movably connected to the cylinder seat 272, and the telescopic end of the electric push rod 273 is movably connected to the swing plate 271. The telescopic extension of the electric push rod 273 drives the swing plate 271 to rotate. Both ends of the pair of first guide rollers 274 are provided with roller shafts. The roller shafts at both ends of the pair of first guide rollers 274 respectively pass through the adjustment groove 5 and are inserted into the first bearings 7 at both ends of the swing plate 271. Through the movable connection between the electric push rod 273 and the cylinder seat 272 and the swing plate 271, the swing plate 271 is driven to rotate about the central movable setting as the axis, thereby adjusting the height change at both ends of the swing plate 271, that is, adjusting the position of the first guide rollers 274.

[0032] More specifically, when the electric push rod 273 extends or retracts, it drives the swing plate 271 to rotate around the central movable connection point through the movable connection with the cylinder seat 272 and the swing plate 271. During the rotation of the swing plate 271, the height of both ends changes, which in turn drives the first guide roller 274 inserted in the first bearing 7 to move along the adjustment groove 5 to achieve position adjustment. By adjusting the position of the first guide roller 274, the tension of the glass fiber cloth during the conveying process can be flexibly adjusted, and the first guide roller 274 used for guidance can be replaced according to the coating requirements without complicated disassembly operations.

[0033] As a preferred embodiment, the coating structure further includes a driving unit 3 and a supporting unit 4; the driving unit 3 is fixedly disposed on the base 1, the supporting unit 4 is fixedly disposed on the driving unit 3, and the supporting unit 4 can be translated and rotated 90 degrees by the driving unit 3.

[0034] As a preferred embodiment, the drive unit 3 further includes an electric slide rail 31, a connecting shaft 32, a gear 33, and a limiting frame 34. The electric slide rail 31 is fixedly mounted on the upper left wall of the base 1, and is located in front of the centerline. A sliding block for left and right movement is provided on the electric slide rail 31, and a second bearing 8 is embedded in the middle of the sliding block. One end of the connecting shaft 32 is fixedly inserted into the middle of the second bearing 8, and the connecting shaft 32 can rotate through the second bearing 8. The gear 33 is fixedly fitted into the middle of the connecting shaft 32, and the gear 33 is located on the electric slide rail 31. Above, one end of the limiting frame 34 is fixedly mounted on the upper wall of the base 1 and fits against the side wall of the electric slide rail 31. The other end of the limiting frame 34 corresponds to the gear 33, and the side wall of the other end of the limiting frame 34 is provided with teeth that can mesh with the gear 33. The other end of the limiting frame 34 is provided with an L-shaped groove 6 that communicates with the side wall of the teeth. The electric slide rail 31 drives the bearing unit 4 to move, causing the gear 33 to contact the teeth on the side wall of the limiting frame 34 and be subjected to force, thereby causing the gear 33 to rotate, which drives the bearing unit 4 to rotate synchronously and adjust its direction during the translation process.

[0035] More specifically, after the electric slide rail 31 is started, it drives the slide base and the above adapter shaft 32, gear 33, and bearing unit 4 to move left and right synchronously. During the translation, the gear 33 contacts the teeth on the side wall of the limit frame 34 and is subjected to force, thereby driving the gear 33 to rotate. The gear 33 drives the adapter shaft 32 to rotate synchronously, realizing the linkage between translation and rotation. Through the above linkage structure, the bearing unit 4 fixed to the other end of the adapter shaft 32 is driven to complete the direction adjustment while translating, and finally realize the left and right translation and 90-degree rotation of the bearing unit 4, providing a guarantee for the replacement of the coating structure and the precise docking with the drying structure 2.

[0036] As a preferred embodiment, the supporting unit 4 further includes a material base 41, a pair of first baffles 42, a pair of second baffles 43, a second guide roller 44, several roller frames 45, several third guide rollers 46, and a locking rod 47. The material base 41 is rectangular, and an arc-shaped roller groove is formed in the middle of the upper wall of the material base 41. The lower wall of the material base 41 near one end is fixedly mounted on the other end of the adapter shaft 32. The material base 41 is eccentrically positioned. The pair of first baffles 42 are detachably mounted on the upper wall of the material base 41 and are symmetrical to each other. The pair of first baffles 42 are both right-angled trapezoidal structures, and the first baffles 42 have inclined walls on opposite sides. The pair of second baffles 43 are detachably fastened to both ends of the first baffles 42, and the lower wall of the second baffles 43 is flush with the upper wall of the first baffles 42. The upper walls of the material base 41 are sealed together. The two ends of the second guide roller 44 are movably inserted between the second baffles 43. Several roller frames 45 are T-shaped and are symmetrically arranged on the side walls of the first baffle 42. Several third guide rollers 46 are movably arranged between the roller frames 45, and the third guide rollers 46 are located above the first baffle 42. One end of the locking rod 47 is fixed to the lower wall of the material base 41, and the other end of the locking rod 47 is movably inserted into the groove 6 of the limiting frame 34. The material base 41 supports the first baffle 42 and the second baffle 43 to form a box with an inclined inner wall, which is used to centrally store the coating, so that the material can be effectively dipped after being guided by the second guide roller 44. It can also be disassembled for easy disassembly and cleaning later.

[0037] More specifically, the combination of the detachable first baffle 42, second baffle 43 and material seat 41 forms an enclosed space with an inclined inner wall, which can centrally store different types of coatings to meet the needs of multiple coatings. The fiberglass cloth is guided by the second guide roller 44 and smoothly enters the coating space to complete the dip coating operation. The inclined side wall of the first baffle 42 can ensure the uniform distribution of coatings and improve coating consistency. The third guide roller 46, together with the first guide roller 274 of the drying structure 2, realizes the continuous connection of the cloth conveying path after the carrying unit 4 is rotated 90 degrees to avoid deviation. The first baffle 42 and the second baffle 43 are both detachable, which facilitates the cleaning of coating residues, component inspection and coating replacement, and greatly reduces maintenance costs. The locking rod 47 and the sliding groove 6 of the limit frame 34 play a temporary limiting role in the translation and rotation of the carrying unit 4. When the material seat 41 is rotated from parallel to the electric slide rail 31 to relatively perpendicular, the locking rod 47 moves out of the sliding groove 6 to release the limit.

[0038] As a preferred option, the material holder 41 is rotated 90 degrees by the meshing of the gear 33 with the teeth of the limiting frame 34, so that the third guide roller 46 is parallel to the first guide roller 274; when the material holder 41 is rotated from parallel to the electric slide rail 31 to relatively perpendicular, the locking rod 47 moves out of the limiting frame 34 from one end of the slide groove 6.

[0039] Its detailed connection method is a well-known technology in this field. The following mainly introduces the working principle and process, and the specific work is as follows.

[0040] First, the equipment is placed stably on the base 1. According to the actual drying production line requirements, the base 1 can be connected through the first adapter claw 9. Then, multiple drying structures 2 are arranged and set up. The drying box 22 in the drying structure 2 is supported at a certain height by the bracket 21, and the drying box 22 is relatively stably connected through the second adapter claw 26 to realize the splicing and combination of the production line. Alternatively, the bracket 21 can be used to maintain the corresponding spacing by being located at the installation position of the base 1.

[0041] Then, the two sets of coating structures are symmetrically arranged at the left end of the base 1 as the input side. When the equipment is used for coating, one set of coating structures is started, that is, the electric slide rail 31 in the drive unit 3 is started, which drives the bearing unit 4 to move to the left. At this time, when the material seat 41 and the electric slide rail 31 are in a horizontal state, the locking rod 47 on the lower wall of the material seat 41 is inserted into the slide groove 6 of the limit frame 34 for limitation, that is, the bearing unit 4 moves linearly along the limit frame 34.

[0042] When one end of the seat rod moves to the end of the slide 6, the gear 33 meshes with the teeth of the side wall of the limit frame 34, and rotates under the force of the gear 33, which in turn drives the adapter shaft 32 to rotate with the help of the second bearing 8, and finally drives the bearing unit 4 to rotate 90 degrees; causing the material seat 41 to rotate from being horizontal with the electric slide rail 31 to being relatively vertical, and then the third guide roller 46 and the second guide roller 44 are relatively parallel to the first guide roller 274;

[0043] At this time, the fiberglass cloth is guided by the third guide roller 46 on the roller frame 45 into the space between the first baffles 42, and then passes through the second guide roller 44 between the second baffles 43 before entering the leftmost drying box 22. If the same coating is applied, the fiberglass cloth can be alternately passed through the first guide roller 274 for drying and conveying. The fiberglass cloth that alternately passes through the first guide roller 274 is extended and retracted by the electric push rod 273 in the switching unit 27, which drives the swing plate 271 to be rotated under force, thereby driving the first guide roller 274 to move along the arc-shaped adjustment groove 5, thereby changing the height position of both ends of the swing plate 271, so that a certain degree of tension adjustment can be achieved in each drying box 22.

[0044] When two coatings are applied, the fiberglass cloth only needs to be guided by the first guide roller 274 at one end of the swing plate 271 as it passes through the drying box 22. The fiberglass cloth drives the first guide roller 274 to rotate with the help of the first bearing 7 during the conveying process. When the coating is changed, the coating structure is replaced, and the electric push rod 273 is activated to adjust the height of the first guide roller 274 to prevent mixing.

[0045] When the bearing unit 4 is reset, after the gear 33 rotates 90 degrees, the locking rod 47 on the lower wall of the material seat 41 is re-embedded in the slide groove 6 and moves linearly under the obstruction of the limiting frame 34; for subsequent maintenance, the second baffle 43 can be removed first, then the corresponding second guide roller 44 can be removed, and finally the first baffle 42 can be removed.

[0046] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
