Description

Technical Field

[0001] The utility model relates to the technical field of glass fiber slitting devices, in particular to a glass fiber slitting and rewinding device. Background Art

[0002] Glass fiber can be used in the circuit board industry because of its good insulation, heat resistance, and mechanical strength. Specifically, the sheet-shaped glass fiber material is laid between the layers of a multi-layer circuit board to achieve its insulation effect. Therefore, the glass fiber needs to be striped or sliced ​​before laying so that it matches the size of the circuit board.

[0003] In the application process of existing glass fiber, a strip cutting device is used to cut wide glass fiber into strips and slices before laying it for use. The wide glass fiber is cut in two directions perpendicular to each other within its surface and then formed into sheet glass fiber materials for stacking. Stacking will result in poor integrity between multiple sheet materials, making them difficult to store or transport. In addition, the existing cutting method generally uses a cutting knife to cut the glass fiber on one side. This cutting method is prone to burrs and rough edges on the side after cutting, which affects the quality of the cut strips and thus affects the normal use of the glass fiber. Deburring may be required later. Utility Model Content

[0031] The following are specific embodiments of the present invention and the accompanying drawings to further describe the technical solution of the present invention, but the present invention is not limited to these embodiments.

[0032] like Figures 1 to 8 As shown, a glass fiber slitting and rewinding device includes a slitting device 100 and a rewinding device 200. The slitting device 100 includes a frame 10, a loading mechanism 1, a slitting mechanism 2 and a feeding mechanism 3. The feeding mechanism 1 is arranged on the frame 10 for loading wide-width glass fibers 300. The slitting mechanism 2 includes a rotating shaft 2a and a mounting frame 22 arranged on the frame 10. Four circular knives 210 are arranged on the rotating shaft 2a. Four pneumatic slitting knives 220 are arranged on the mounting frame 22. The pneumatic slitting knives 220 and the circular knives 210 are close to each other and staggered and abutted to jointly cut the wide-width glass fibers 300 fed by the loading mechanism 1 into narrow-width glass fibers. The feeding mechanism 3 is arranged on the frame 10 for feeding the narrow-width glass fibers. The rewinding device 200 is arranged beside the slitting device 100 for rewinding the narrow-width glass fibers.

[0033] In the present invention, the wide glass fiber 300 that has not been cut into strips is placed on the feeding mechanism 1, and the feeding mechanism 1 and the feeding mechanism 3 provide power to feed the glass fiber. Therefore, the wide glass fiber 300 passes through the stripping mechanism 2 from bottom to top, and the rotating shaft 2a in the stripping mechanism 2 drives the four circular knives 210 to rotate. After the pneumatic slitting knife 220 is started, it approaches the circular knife 210 and forms a state of offset contact with the circular knife 210. The sides of the two that are close to each other rotate in the same direction (for example, both sides that are close to each other rotate upward or both rotate downward). ), the wide glass fiber 300 located between the two is cut. This cutting method is similar to the action of cutting with scissors, replacing the conventional cutting method of using a circular knife 210 or a pneumatic slitting knife 220 alone to pierce the wide glass fiber 300. The wide glass fiber 300 can be cut into strips more smoothly, and the formation of burrs at the cutting position can be avoided, thereby improving the quality of the cutting and stripping. The narrow glass fiber after cutting and stripping continues to be conveyed by the feeding mechanism 3, and is wound into a roll at the rewinding device 200. Since the utility model has four circular knives 210 and four pneumatic slitting knives 220 respectively, the knives on both sides are used to cut and remove the side burrs of the wide glass fiber 300 respectively, and the middle knife is used to cut and strip the wide glass fiber 300 into three narrow glass fibers, and the three narrow glass fibers are wound into three independent rolls by the rewinding device 200 for later use; and it is precisely because of the coordinated use of the circular knife 210 and the pneumatic slitting knife 220 that the appearance of side burrs of the narrow glass fiber after cutting and stripping is avoided, it is more convenient to store or use the narrow glass fiber in a roll form, and there is no need to remove the burrs of the narrow glass fiber in a rolled or spread state later, thereby improving the cutting quality and processing efficiency.

[0034] like Figure 4As shown, the feeding mechanism 1 includes a lower bracket 122 and a mounting plate 112. The lower bracket 122 is arranged on the frame 10, and a feeding roller 1c for carrying the wide glass fiber 300 is rotatably provided thereon. The mounting plate 112 is arranged on the frame 10, and a first rotating shaft 1a is rotatably provided thereon. After the first rotating shaft 1a abuts against the second rotating shaft 1b on the frame 10, the wide glass fiber 300 on the feeding roller 1c is fed to the slitting mechanism 2. The first rotating shaft 1a and the first motor 111 are both arranged on the mounting plate 112. The mounting plate 112 is movably arranged on the frame 10 through the first guide rail pair 1132, and can be driven by the first cylinder 1131 to translate to realize the translation of the first rotating shaft 1a. When the first cylinder 1131 drives the first rotating shaft 1a driven by the first motor 111 to move toward the second rotating shaft 1b and abut against it, the clamping friction and mutual movement between the two can enable the wide glass fiber 300 passing through the two to be moved and fed. Matching with it, the unloading roller 1c can also rotate, and a gear is fixed at one end of it, and the unloading roller 1c can be driven to rotate by meshing the gear with the gear at the output end of the second motor 121 arranged on the lower bracket 122; to facilitate the rotation of the unloading roller 1c, rollers 124 can also be fixed at both ends of it, and the rotation of the unloading roller 1c is realized by the rotation of the roller 124 on the lower bracket 122; a rolling groove 1221 is provided on the lower bracket 122, and the roller 124 can rotate or roll in situ in the rolling groove 1221. When it is necessary to position the unloading roller 1c carrying the wide glass fiber 300 on the lower bracket 122, the roller 124 and the rolling groove 1221 are used to rotate the unloading roller 1c. The cooperation of 221 and the rolling of roller 124 in the rolling groove 1221 can realize the precise meshing of the gear on the discharge roller 1c and the gear at the output end of the second motor 121, so that the second motor 121 can drive the discharge roller 1c to rotate subsequently, and a push-down cylinder 1251 is arranged on the lower bracket 122, and a lower pressure block 1252 with an arc surface structure is arranged at the output end of the push-down cylinder 1251. The arc surface of the lower pressure block 1252 abuts against the arc surface of the roller 124, which can limit the translation of the roller 124 to prevent the two meshing gears from disengaging, and the abutment between the roller 124 and the lower pressure block 1252 will not affect the normal rotation of the discharge roller 1c.

[0035] The feeding mechanism 1 further includes a sensor 1233. A hydraulic cylinder 1231 is provided on the frame 10. The lower bracket 122 is horizontally slidably arranged on the frame 10 through the second guide rail pair 1232, and is connected to the output end of the hydraulic cylinder 1231. The sensor 1233 is used to detect the side of the wide glass fiber 300. When the side of the wide glass fiber 300 is offset during the feeding process, the sensor 1233 feeds back the offset information to the system to control the hydraulic cylinder 1231 to drive the lower bracket 122 to translate along the second guide rail pair 1232 to adjust the side of the wide glass fiber 300 to be located at the correct feeding position, thereby ensuring the accuracy of cutting and slitting.

[0036] like Figure 5 and 6 As shown, the mounting frame 22 includes a fixed frame 221 and an adjustment frame 222. The fixed frame 221 is arranged on the frame 10. The fixed frame 221 is provided with a horizontal guide rail. The number of the adjustment frames 222 matches the number of the pneumatic slitting knives 220 and is also four. The four adjustment frames 222 are respectively arranged on the guide rails through sliders 2221 to be horizontally slidable for carrying the pneumatic slitting knives 220. The position of the pneumatic slitting knives 220 can be adjusted by setting the position of the adjustment frame 222 relative to the fixed frame 221, so as to meet the requirements of cutting the wide width glass fiber 300 of different widths and the requirements of cutting it into narrow width glass fibers of different widths. In addition, a first heating plate 24 can be arranged on the side of the adjustment frame 222 close to the circular knife 210 to heat the wide width glass fiber 300 before cutting and stripping to make it soft and easy to cut, and to reduce the burrs and cutting debris after cutting.

[0037] As shown in Figure 2, the glass fiber slitting and rewinding equipment also includes a side material collecting mechanism 5. A pair of side material collecting mechanisms 5 are arranged on the frame 10 and are located above the pneumatic slitting knife 220 on the side. The side material collecting mechanism 5 includes a rotating motor arranged on the frame 10 and a winding roller arranged at the output end of the rotating motor, which can reel in the waste side materials cut from both sides of the wide glass fiber 300.

[0038] like Figure 7 As shown, the feeding mechanism 3 includes an upper material guide roller 3a, a first active feeding roller 3b, a first driven feeding roller 3b′, a second active feeding roller (not shown), a second driven feeding roller 3c′ and a lower material guide roller 3e. The first active feeding roller 3b and the second active feeding roller are respectively driven to rotate by a third motor 311, and the first driven feeding roller 3b′ and the second driven feeding roller 3c′ are respectively driven to move downward by a vertical cylinder 3111 and abut against the first active feeding roller 3b and the second active feeding roller, and are used to feed the narrow width glass fiber cut by the slitting mechanism through friction and rotation.

[0039] The feeding mechanism 3 also includes an adjustment component, which includes a lifting cylinder 321 arranged on the frame 10, and a tensioning roller 3d arranged at the output end of the lifting cylinder 321. The tensioning roller 3d is located between multiple driven feeding rollers. The lifting and lowering of the tensioning roller 3d driven by the lifting cylinder 321 can realize the tensioning and feeding of the narrow width glass fiber after cutting and slitting.

[0040] Combination Figure 3 and Figure 8As shown, a cutting mechanism 4 can also be arranged on the frame 10 in the slitting device 100. The cutting mechanism 4 is arranged above the feeding mechanism 3, and includes a driving motor 411, a transmission shaft 412, a cam rod 413 and a cutting knife 414. The transmission shaft 412 is rotatably arranged on the frame 10 and is connected to the driving motor 411. Two cam rods 413 are arranged on the transmission shaft 412, and a cutting knife 414 is arranged at the lower end. Both sides of the cutting knife 414 are embedded in the vertical slide groove 4141 on the frame 10. The driving motor 411 drives the transmission shaft 412 to drive the cam rod 413 to swing up and down, and drives the cutting knife 414 to move vertically along the vertical slide groove 4141 to realize the cutting action of multiple narrow glass fibers, so that the narrow glass fibers can be cut into sheets for use; a second heating plate 33 can also be arranged on the frame 10 to heat the narrow glass fibers before being cut by the cutting mechanism 4. It should be noted that when the cutting mechanism 4 is used, it is not necessary to rewind the narrow width glass fiber through the rewinding device 200 .

[0041] In addition, a dust suction duct 60 may be provided on the frame 10, which is connected to the first dust suction port 23 beside the pneumatic slitting knife 220 and the second dust suction port 42 beside the cutting knife 414 for absorbing cutting debris.
