Description

Technical Field

[0001] The present invention belongs to the technical field of optical fiber cable processing equipment, and particularly relates to an optical fiber cable synchronous feeding and cutting device. Background Art

[0002] In the existing Chinese patent database, a patent named an optical fiber cable cutting device is disclosed, with the application number CN202022677912.6 and the application date November 19, 2020. An optical fiber cable cutting device includes a machine body. A bearing is fixedly connected to the top of the machine body. A driven gear is fixedly connected to the inner cavity of the bearing. A first threaded rod is threadedly connected to the axis of the driven gear. The bottom of the first threaded rod penetrates into the inner cavity of the machine body and is fixedly connected to a cutting knife. The right side of the driven gear meshes with a driving gear. A motor is fixedly connected to the top of the driving gear. The top of the motor is fixedly connected to a mounting plate. The bottom of the mounting plate is fixedly connected to the top of the machine body. By the combined use of the machine body, bearing, driven gear, first threaded rod, cutting knife, driving gear, motor, mounting plate, storage battery, clamping plate, second threaded rod and base, the present utility model can automatically cut the optical fiber cable, saving time and effort, greatly improving the installation efficiency, and bringing great convenience to communication work.

[0003] Currently, when cutting optical fibers, scissors are used to process each optical fiber. The operator needs to hold the optical fiber by hand, run along the path of the optical fiber, and quickly cut the optical fiber with scissors, resulting in very low efficiency. At the same time, the cutting length of the optical fiber needs to be manually determined, which is relatively difficult to operate for longer optical fibers, easily leading to uneven lengths of the cut optical fibers and non-smooth and flat cut surfaces. The manual operation process is also time-consuming and laborious. This solution aims to propose an optical fiber cable synchronous feeding and cutting device that can integrate feeding and cutting, and synchronously cut the optical fiber cable after feeding is completed. Summary of the Invention

[0004] The technical problem to be solved by the present invention is how to complete the automatic cutting of optical fiber cables, and at the same time overcome the need for manual feeding in the prior art, and be able to complete the feeding and cutting of optical fiber cables in sequence and synchronously. To improve its deficiencies, the present invention provides an optical fiber cable synchronous feeding and cutting device.

[0005] To achieve the above object, the present invention is realized through the following technical solutions:

[0006] An optical fiber cable synchronous feeding and cutting device includes a workbench, on which a set of upper conveying wheels and lower conveying wheels are arranged. A number of limiting blocks are arranged on the surface of the upper conveying wheel. Each limiting block is radially and uniformly distributed with the axis of the upper conveying wheel as the center line. A swing block is rotatably connected to the center of the upper conveying wheel. A swing claw for abutting against the limiting block is arranged on the swing block. The swing claw is rotatably connected to the swing block through a pin shaft. A torsion spring is also arranged on the pin shaft. An extension section is integrally arranged on the side surface of the swing block. A through hole for the limiting block to pass through is opened on the extension section. A fixing plate is arranged on the upper surface of the workbench. A limiting shaft is integrally arranged on the upper part of the fixing plate. The lower surface of the extension section is lapped on the limiting shaft. A first shaft body is arranged on the back of the fixing plate. A second shaft body is arranged on the back of the free end of the extension section. A tension spring is arranged between the first shaft body and the second shaft body. A driving runner is arranged on the workbench. A number of abutting blocks for swinging the extension section are arranged on the driving runner. A cutting component is also arranged on the back of the extension section. When the extension section is lapped on the limiting shaft, the cutting blade in the cutting component is perpendicular to the tabletop of the workbench, and a through hole is opened on the workbench directly below the cutting component.

[0007] As a preferred solution, the cutting component includes a fixing seat fixed to the back of the extension part. A blade mounting seat is connected to the bottom of the fixing seat. The blade mounting seat includes a U-shaped part bolted to the fixing seat. A vertical plate part is integrally arranged on the outer surface of the middle section of the U-shaped part. A blade slot is opened on the lower surface of the vertical plate part. The root of the cutting blade is arranged in the blade slot and is connected to the vertical plate part through a bolt.

[0008] As a preferred solution, a vertical plate is integrally arranged on the edge of the upper surface of the workbench. The upper conveying wheel and the driving runner are both rotatably connected to the vertical plate.

[0009] As a preferred solution, a motor mounting plate is arranged on the back of the vertical plate. A driving motor is arranged on the motor mounting plate.

[0010] As a preferred solution, the abutting block is arranged in a T shape. The horizontal section of the abutting block is fixed to the surface of the driving runner through a bolt, and the free end of the vertical section of the abutting block protrudes from the outer peripheral surface of the driving runner.

[0011] As a preferred solution, a number of weight-reducing holes are opened on the driving runner.

[0012] Compared with the prior art, the beneficial effects of the present invention are:

[0013] 1. The device drives the rotating wheel to rotate, squeezes the extension section to rotate counterclockwise, and makes the upper conveying wheel rotate counterclockwise by swinging the claw against the limit block, so that the upper conveying wheel cooperates with the lower conveying wheel to feed the optical fiber cable forward until the resistance block on the driving rotating wheel is separated from the extension section. Due to the reset effect of the tension spring, the extension section instantly swings clockwise at high speed, so that the cutting component cuts the optical fiber cable on the workbench;

[0014] 2. During the rotation of the driving wheel, due to the intermittent contact between the several abutment blocks and the extension section, the optical fiber and cable that have been cut can be discharged, and the next section of optical fiber and cable to be cut can be fed at the same time;

[0015] 3. The detachable setting of the cut-off component improves the convenience of replacement after long-term use, thereby ensuring the flatness of the cut end surface of the optical fiber cable; the device is suitable for industrial production and has strong practicality.

DETAILED DESCRIPTION

[0021] The technical solution of the present application is further described below in conjunction with the accompanying drawings and embodiments.

[0022] like Figures 1-4As shown in the figure, it is a synchronous feeding and cutting device for optical fiber cables, including a workbench 1. A set of upper conveying wheels 2 and lower conveying wheels 3 are arranged on the workbench 1. A number of limiting blocks 4 are arranged on the surface of the upper conveying wheel 2. Each limiting block 4 is radially and evenly distributed with the axis of the upper conveying wheel 2 as the center line. A swing block 5 is rotatably connected at the center of the upper conveying wheel 2. A swing claw 6 for abutting against the limiting block 4 is arranged on the swing block 5. The swing claw 6 is rotatably connected to the swing block 5 through a pin shaft 7. A torsion spring is also arranged on the pin shaft 7. An extension section 8 is integrally arranged on the side surface of the swing block 5. A through hole 9 for the limiting block 4 to pass through is opened on the extension section 8. A fixing plate 10 is arranged on the upper surface of the workbench 1. A limiting shaft 11 is integrally arranged on the upper part of the fixing plate 10. The lower surface of the extension section 8 is lapped on the limiting shaft 11. A first shaft body 12 is arranged on the back of the fixing plate 10. A second shaft body 13 is arranged on the back of the free end of the extension section 8. A tension spring 14 is arranged between the first shaft body 12 and the second shaft body 13. A driving runner 15 is arranged on the workbench 1. A number of abutting blocks 16 for swinging the extension section 8 are arranged on the driving runner 15. A cutting assembly is also arranged on the back of the extension section 8. When the extension section 8 is lapped at the limiting shaft 11, the cutting blade 17 in the cutting assembly is arranged perpendicular to the tabletop of the workbench 1. A through hole 18 is opened on the workbench 1 directly below the cutting assembly. The cutting assembly includes a fixing seat 19 fixed to the back of the extension part. The bottom of the fixing seat 19 is connected with a blade mounting seat 20. The blade mounting seat 20 includes a U-shaped part bolted to the fixing seat 19. A vertical plate part is integrally arranged on the outer surface of the middle section of the U-shaped part. A blade clamping groove 21 is opened on the lower surface of the vertical plate part. The root of the cutting blade 17 is arranged in the blade clamping groove 21 and is connected with the vertical plate part through a bolt. A vertical plate 22 is integrally arranged on the edge of the upper surface of the workbench 1. Both the upper conveying wheel 2 and the driving runner 15 are rotatably connected to the vertical plate 22. A motor mounting plate 23 is arranged on the back of the vertical plate 22. A driving motor 24 is arranged on the motor mounting plate 23. The abutting block 16 is arranged in a T shape. The horizontal section of the abutting block 16 is fixed on the surface of the driving runner 15 through a bolt. The free end of the vertical section of the abutting block 16 protrudes from the outer peripheral surface of the driving runner 15. A number of weight-reducing holes 25 are opened on the driving runner 15.

[0023] During operation, the operator passes the optical fiber cable through between the upper conveying wheel 2 and the lower conveying wheel 3 until one end of the optical fiber cable abuts against the left end face of the cutting blade 17. Then, the driving motor 24 is started to rotate the driving runner 15. The abutting block 16 rotates clockwise along with the driving runner 15. When it contacts the extension section 8, it drives the extension section 8 and the swing block 5 to rotate counterclockwise. After the upper part of the swing claw 6 connected to the swing block 5 abuts against the limit block 4, while squeezing the limit block 4, the upper conveying wheel 2 and the lower conveying wheel 3 rotate towards each other linearly, thus completing the feeding of the optical fiber cable. The horizontal feeding of the optical fiber cable continues until the abutting block 16 on the driving runner 15 disengages from the extension section 8. At this time, due to the reset action of the tension spring 14, the swing block 5 rotates clockwise to return to its original position until the extension section 8 is lapped on the limit shaft 11 on the upper part of the fixed plate 10. During the clockwise rotation of the swing block 5, the cutting blade 17 in the cutting component cuts the optical fiber cable located at the through hole 18. When the next abutting block 16 contacts the extension section 8, the previous actions are repeated, and at the same time, the subsequent optical fiber cable pushes the already cut optical fiber cable for discharging;

[0024] Due to the setting of the torsion spring, the swing claw 6 can only abut against the limit block 4 and rotate counterclockwise. When the swing block 5 rotates clockwise to reset, after the lower part of the swing claw 6 contacts the limit block 4, the swing claw 6 swings counterclockwise, so that the swing block 5 can continue to swing clockwise. In this solution, the upper rotating wheel is set to only rotate counterclockwise, and at the same time, the lower rotating wheel is set to only rotate clockwise to ensure the feeding stability of the optical fiber cable.

[0025] The present invention is not limited to the above embodiments. Based on the technical solutions disclosed in the present invention, those skilled in the art can make some substitutions and deformations to some technical features without creative labor according to the disclosed technical content, and these substitutions and deformations are all within the protection scope of the present invention.
