Description

Technical Field

[0001] The invention relates to the technical field of glass fiber production and processing, in particular to a wire drawing and plastic coating device for glass fiber production and processing. Background Art

[0002] Glass fiber is a thin filament made of glass, commonly used to enhance the strength and durability of materials. Its primary component is silicate, produced through processes such as melting and drawing. Glass fiber boasts lightweight, high strength, corrosion resistance, and insulation properties, making it widely used in construction, automotive, aerospace, electronics, and sports equipment. During production and processing, the fiberglass filaments are coated with a plastic material to enhance their corrosion resistance, wear resistance, weather resistance, and electrical insulation.

[0003] The Chinese invention patent with announcement number CN119528428B discloses a drawing and coating device for glass fiber production and processing, including a base, a first vertical frame is fixedly installed on one side of the top of the base, a mounting seat is fixedly installed on the top of the first vertical frame, a drawing mechanism is fixedly installed on the side of the mounting seat away from the first vertical frame, a second vertical frame is fixedly installed on the top of the base close to the first vertical frame, a heating crucible used in conjunction with the drawing mechanism is fixedly installed on the top of the second vertical frame, a plastic coating part is fixedly installed on the bottom of the drawing mechanism, and a winding mechanism is fixedly installed on the top of the base. This invention sets a drawing mechanism and uses the plastic coating part and the winding mechanism in combination to perform glass fiber drawing and plastic coating processing and continuous and uniform winding and winding of the glass fiber without stopping the machine, reducing the accumulation of glass liquid, thereby improving the overall drawing efficiency of the glass liquid.

[0004] However, the above patent still has the following shortcomings during actual use: the patent starts the second motor to drive the second worm to drive the second worm wheel to rotate, so that the cutting disk can rotate synchronously with the buffer frame to prevent the glass solution from leaking, but the rotation angle of the cutting disk is limited by the two mounting frames. When the drawing crucible on the left needs to be used, the fixed auxiliary frame just contacts the two mounting frames. The buffer frame can rotate in the opposite direction and the drawing crucible on the left replaces the drawing crucible at the bottom, but the fixed auxiliary frame cannot rotate in the opposite direction, which causes the drawing crucible at the bottom to be unable to be sealed by the cutting disk, resulting in leakage of the glass solution.

Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0022] See also Figure 1-10 The present invention describes the above technical solution in detail through the following embodiments: A drawing and plastic coating device for glass fiber production and processing, comprising a base 1, a vertical frame 2 and a winding mechanism 3, wherein a heating crucible 4, a drawing mechanism 5 and a plastic coating part 6 are sequentially arranged on the vertical frame 2 from top to bottom, a discharge valve 41 is provided at the bottom of the heating crucible 4, the drawing mechanism 5 comprises a first suspension 51, a circular buffer frame 52 and a second suspension 53, a rotating mechanism 54 is provided on the first suspension 51, four embedded grooves 521 arranged at equal angles around the circumference of the circular buffer frame 52 are provided on the inner bottom wall, a detachable fan-shaped drawing crucible 522 is provided in the embedded groove 521, the four fan-shaped drawing crucibles 522 have different numbers of holes, and a rotating card is provided at the center of the inner bottom wall of the circular buffer frame 52. A mounting column 523 is provided, on which two symmetrically arranged partition scrapers 524 are provided, and a feeding area 525 is formed between the two partition scrapers 524. A cutting assembly 55 for selectively opening the bottom of a fan-shaped drawing crucible 522 is provided on the second suspension 53. The first suspension 51 and the second suspension 53 are spaced apart from top to bottom on the longitudinal frame 2. The circular buffer frame 52 is rotatably arranged on the first suspension 51. The rotating mechanism 54 is transmission-connected to the circular buffer frame 52. The cutting assembly 55 is arranged on the second suspension 53. The bottom of the circular buffer frame 52 is arranged in the cutting assembly 55. The longitudinal frame 2 and the winding mechanism 3 are both arranged on the base 1.

[0023] The present invention adopts a circular buffer frame 52, which can be driven to rotate by a rotating mechanism 54, so that the feeding area 525 can be docked with another fan-shaped drawing crucible 522, and the partition scraper 524 can transfer the glass solution in the feeding area 525. The fan-shaped drawing crucible 522 docked with the feeding area 525 can be opened by the cutting assembly 55, and the remaining three fan-shaped drawing crucibles 522 are blocked by the cutting assembly 55, thereby avoiding leakage of the glass solution.

[0024] When using this device, first connect the coating solvent output system to the coating part 6, and then introduce the glass solution into the heating crucible 4 for heating. After the heating is completed, open the discharge valve 41, and the glass solution can be directly discharged into the feeding area 525. When it is necessary to change the fan-shaped drawing crucible 522 connected to the feeding area 525, first drive the circular buffer frame 52 to rotate through the rotating mechanism 54. The rotating mechanism 54 includes two first rotating seats 541, a first motor 542, a worm 543 and a worm gear 544. The two first rotating seats 541 are symmetrically arranged on the top of the first suspension 51, the first motor 542 is arranged on the outer wall of one of the first rotating seats 541, and the worm 543 is rotatably arranged on the two first rotating seats 541, and one end of the worm 543 is connected to the output end of the first motor 542, and the worm gear 544 is arranged on the outer wall of the circular buffer frame 52, and the worm gear 544 is engaged with the worm 543.

[0025] The first motor 542 drives the worm 543 to rotate. After the worm 543 rotates, it drives the worm wheel 544 to rotate. The worm wheel 544 drives the circular buffer frame 52 to rotate on the first suspension 51. The mounting column 523 and the cutting assembly 55 do not rotate synchronously with the circular buffer frame 52. Therefore, the positions of the two partition scrapers 524 will not change. The two partition scrapers 524 can scrape and drive the glass solution in the feeding area 525 synchronously, so that the glass solution always remains in the feeding area 525. After the feeding area 525 is docked with the fan-shaped drawing crucible 522 that needs to be replaced, the first motor 542 stops working.

[0026] In this process, the cutting component 55 can cut the filamentous glass fiber. The cutting component 55 includes a plug-in block 551 with a polygonal cross section, an annular guide rail 553, an annular slider 554 and a round bottom plate 552.

A blade 5522 is provided at the notch 5521, an arc-shaped connecting strip 5523 is provided at the top of the circular bottom plate 552, the insert block 551 is arranged at the bottom of the mounting column 523, the annular guide rail 553 is arranged on the outer wall of the circular buffer frame 52, the annular slider 554 is slidably set on the annular guide rail 553, the second suspension 53 is fixedly connected to the annular slider 554, the arc-shaped connecting strip 5523 is fixedly connected to the bottom of the annular slider 554, and the circular bottom plate 552 is in conflict with the bottom of the fan-shaped drawing crucible 522.

[0027] After the circular buffer frame 52 rotates, the four fan-shaped drawing crucibles 522 also rotate synchronously with the circular buffer frame 52. The fan-shaped drawing crucible 522 that is discharging filamentous glass fibers gradually approaches the blade 5522, and the blade 5522 can cut the filamentous glass fibers one by one. Then, the bottom of the fan-shaped drawing crucible 522 gradually collides with the inner bottom wall of the circular bottom plate 552. The fan-shaped drawing crucible 522 is blocked by the circular bottom plate 552. The polygonal cross-section plug 551 cooperates with the slot to avoid deflection. After that, the next fan-shaped drawing crucible 522 docks with the feeding area 525, and new filamentous glass fibers can be discharged.

[0028] Afterwards, the filamentous glass fiber passes through the plastic-coated part 6, and the filamentous glass fiber is plastic-coated by the plastic-coated part 6.
