[0035] Furthermore, the wire drawing assembly 3 includes a mounting base 24 installed on the upper surface of the workbench 1, and two groups of L-shaped fixing plates 25 are symmetrically bolted on both sides of the mounting base 24, and the L-shaped fixing plates 25 are bolted to the upper surface of the workbench 1. A feeding port is opened on the upper part of the mounting base 24, and a limiting groove 26 is opened on one side of the feeding port of the mounting base 24, and a positioning frame 27 is bolted and installed on the other side of the mounting base 24 corresponding to the limiting groove 26. A second motor 28 is installed on the upper part of the positioning frame 27, and a coupling is keyed to the output end of the second motor 28. The L-shaped fixing plate 25 is used to assist in limiting the mounting base 24, so that the mounting base 24 is more stable to use, and the feeding port opened on the upper part of the mounting base 24 is used to limit the two groups of feeding rollers 29, so that the feeding rollers 29 are more stable when rotating to complete the feeding work.
[0036] It is worth mentioning that two groups of feed rollers 29 are rotatably installed in the upper and lower parts of the feed port, and a group of protective grooves 30 are respectively opened in the middle of each group of feed rollers 29, and one end of the central axis of each group of feed rollers 29 is respectively connected to the coupling key, and the other end of the central axis of the feed roller 29 is rotatably installed in the limit groove 26, and the other end of the central axis of the feed roller 29 extends from the inside of the limit groove 26 and is threadedly installed with a limit nut 31. The protective groove 30 opened in the middle of the feed roller 29 presses the wire to be fed, and the two groups of feed rollers 29 are controlled to rotate relative to each other through the operation of the second motor 28 to continuously complete the wire feeding work.
[0037] Specifically, the wire cutting assembly 4 includes a base 32 installed on the upper surface of the workbench 1, a pressure tester 33 is installed on the upper part of the base 32, two groups of first limit rods 34 are symmetrically installed on the upper surface of the base 32 on both sides of the pressure tester 33, a movable cutter 42 is located on the upper part of the cutting table 35 between the two groups of first limit rods 34, a cutting table 35 is bolted to the top of the pressure tester 33, a V-groove 36 is provided on the upper surface of the cutting table 35, the top of the cutting table 35 is a wire cutting surface, and a cross-shaped V-groove 36 with an angle of 30 degrees and 45 degrees is provided on the wire cutting surface, the 30-degree "V" groove is a V-groove 36 used for the cutter 42 to generate shear force with the cutting knife to cut the glass fiber bundle, and the 45-degree V-groove 36 is a wire feeding groove, which is used to prevent the friction between the glass fiber bundle and the cutting surface of the cutting table 35 from being too large during cutting, thereby affecting the subsequent wire feeding.
[0038] In addition, a second mounting bracket 37 is bolted to the mounting position of the base 32 on the upper surface of the workbench 1, a third motor 38 is mounted at the top center of the second mounting bracket 37, an internal threaded tube 39 is key-connected and mounted on the output end of the third motor 38, an external threaded push rod 40 is threadedly mounted on the internal thread of the internal threaded tube 39, a limit plate 41 is fixedly mounted on the bottom of the external threaded push rod 40, a limit seat 44 is fixedly mounted on the top of the cutter 42, the limit plate 41 is rotatably mounted inside the limit seat 44, two sets of first sleeves 43 are symmetrically mounted on both sides of the cutter 42, and the first sleeves 43 The sliding sleeve is sleeved on the outer arc surface of the first limit rod 34. When the wire cutting operation is performed, the third motor 38 rotates rapidly to drive the cutter 42 to move downward rapidly through the thread, and contacts the glass fiber bundle and the cutting surface of the cutting table 35, thereby generating a shear force on the glass fiber bundle. While generating the shear force, the cutter 42 will generate a downward pressure on the cutting table 35. At this time, the downward pressure acts on the pressure tester 33 through the cutting table 35, and the pressure tester 33 is deformed, thereby detecting whether the pressure during cutting exceeds the limit, in order to prevent damage to the equipment due to excessive pressure during cutting.
[0039] Preferably, the tension testing assembly 5 includes a mounting table 45 mounted on the upper surface of the workbench 1, an electric push rod 46 is fixed on the upper surface of the mounting table 45, two groups of second limit rods 47 are symmetrically installed on the upper surface of the mounting table 45 at the rear side of the electric push rod 46, a pressure gauge 48 is bolted to the top of the electric push rod 46, an L-shaped mounting plate 49 is bolted to the upper surface of the pressure gauge 48, a slide groove 50 is opened in the middle of the L-shaped mounting plate 49, two groups of second sleeves 51 are installed on the rear side of the L-shaped mounting plate 49 corresponding to the two groups of second limit rods 47, and a main force measuring roller is rotatably installed on the front side of the L-shaped mounting plate 49 corresponding to the position of the slide groove 50 52, the Zener side of the L-shaped mounting plate 49 is located on both sides of the main force-measuring roller 52 and two groups of slave force-measuring rollers 53 are symmetrically installed for rotation.

The axes of the slave force-measuring rollers 53 on both sides are in the same horizontal plane. The main force-measuring roller 52 and the slave force-measuring rollers 53 on both sides are arranged alternately, so that when the glass fiber bundle passes through the main force-measuring roller 52 and the two groups of slave force-measuring rollers 53, a certain degree of bending will occur, which will then generate pressure on the pressure gauge 48, thereby generating downward pressure on the main force-measuring roller 52 on the L-shaped mounting plate 49.
[0040] Specifically, the wire feeding assembly 6 includes a base plate 55 installed on the upper surface of the workbench 1, and two groups of third limiting rods 56 are installed in the middle of the upper surface of the base plate 55. A feeding pipe 57 is installed through the middle of the two groups of third limiting rods 56. The two groups of third limiting rods 56 have different heights, which can ensure that the use angle of the feeding pipe 57 corresponds to the use position of the winding assembly 7, thereby ensuring the accuracy of wire feeding.
[0041] It is worth mentioning that the winding assembly 7 includes a frame 58 installed on the upper surface of the workbench 1, a guide roller 59 is rotatably installed on the upper surface of the frame 58, and a winding roller 60 is rotatably installed inside the frame 58.
