The resistance rod 10 is used in conjunction with the lifting assembly to assist in the winding of the glass fiber;

[0042] The wire locking mechanism includes a magnetic strip 81 connected to the inner surface of the knife box 6 and a magnetic sheet 83 movably arranged on the inner side of the magnetic control box 27. The bottom end of the magnetic sheet 83 is fixedly connected with a plurality of blade-attracting magnetic sheets 26 for attracting the blade 9 to realize automatic wire breaking. The blade 9 is an iron blade. The interior of the magnetic control box 27 is connected with a magnetic block 85 through a pair of rotating shafts. The magnetic block 85 is rotated to make it attract or repel the magnetic sheet 83. A baffle plate 84 is arranged between the magnetic sheet 83 and the magnetic block 85. The baffle plate 84 is an iron sheet. A motor 86 is installed on the side of the magnetic control box 27. The output shaft of the motor 86 is fixedly connected to one of the rotating shafts to control the magnetic attraction direction of the magnetic block 85.

[0043] The lifting assembly includes a connecting frame 121 fixedly connected to the lower end of the inner side of the knife box 6, and the other end of the connecting frame 121 is connected to a pair of connecting rods 122 for supporting the magnetic control box 27. The upper end of the connecting rod 122 is fixedly connected to a T-shaped slider 123. The lower surface of the magnetic control box 27 is provided with a pair of slide grooves 126. The two slide grooves 126 are provided with limiting inner grooves 127 for the T-shaped slider 123 to slide. The front surface of the T-shaped connecting plate 13 is provided with a vertical groove 131 for the magnetic control box 27 to slide vertically, and both ends of the T-shaped connecting plate 13 are provided with guide holes 132 for supporting the push rod 142. A through groove for limiting the knife box 6 is provided on the side of one of the support plates 30. The lower end of the through groove is recessed and installed with a hydraulic rod 126. The telescopic end of the hydraulic rod 126 is fixedly connected to the knife box 6. The inner wall of the lower end of the through groove is provided with a touch switch, and the touch switch is electrically connected to the electric telescopic rod a11.

[0044] A pair of wire guide rods 16 are connected to the outer surface of the support plate 4. The two wire guide rods 16 are located above one side of the rotating shaft 17 and are used for wire guiding and auxiliary wire cutting. Before wire cutting, the wire locking mechanism is located in the horizontal middle of the two wire guide rods 16, so that wire cutting and wire locking can be carried out smoothly.

[0045] In this embodiment, the glass fiber is drawn and wound on the outside of the sleeve roller 18. When the wire is wound, it passes through the lower end of the wire guide roller 3 and is located on the outside of the two wire guide rods 16. After the winding is completed, the external hydraulic telescopic rod is started to push the push plate 141 in the direction of the support plate 30, so that the T-shaped connecting plate 13 and the magnetic control box 27 are pushed close to the knife box 6 through the two push rods 142, so that the magnetic sheet 83 contacts the magnetic strip 81, and the motor 86 is started at the same time to drive the magnetic block 85 rotates 180 degrees, at this time, the magnetic block 85 repels the magnetic sheet 83, and the magnetic strip 81 attracts the magnetic sheet 83. A rectangular groove 82 is provided on the outer surface of the magnetic strip 81, so that the magnetic sheet 83 is stuck in the rectangular groove 82, and the silk thread is locked inside it; at the same time, the plurality of blade magnets 26 attract the blade 9, so that the blade 9 automatically moves outward to cut the silk thread. Since the silk thread is clamped between the magnetic strip 81 and the magnetic sheet 83, it will not shrink or loosen. After cutting, the sleeve roller 18 is removed and replaced with a new sleeve roller 18;

[0046] Next, the telescopic ends of the two electric telescopic rods b1422 are retracted to drive the magnetic control box 27 away from the knife box 6, and then the hydraulic rod 126 is started. The hydraulic rod 126 retracts and drives the knife box 6 to move downward. While the knife box 6 moves downward, the magnetic control box 27 is driven to slide downward through the connecting frame 121 and the connecting rod 122. When the bottom end of the knife box 6 contacts the touch switch on the inner wall of the lower end of the through groove, the electric telescopic rod a11 will be immediately started to drive the resistance rod 10 to move close to the sleeve roller 18, so that the silk thread is attached to the outer side of the sleeve roller 18, and the next wire drawing and winding is successfully completed;

[0047] Then, the electric telescopic rod b1422 is extended again, driving the magnetic control box 27 to the inner side of the knife box 6, and then the motor 86 is rotated 180 degrees in the opposite direction, so that the magnetic block 85 generates suction on the magnetic sheet 83, and the suction force of the magnetic block 85 is greater than the suction force of the magnetic strip 81, so that the magnetic sheet 83 stuck in the rectangular groove 82 returns to the inner end of the magnetic control box 27, and the electric telescopic rod b1422 is retracted to drive the magnetic control box 27 away from the knife box 6, and then the slide groove 126 is extended to drive the knife box 6 and the magnetic control box 27 to move upward, and finally the two push rods 142 are restored to their original state, which is convenient for the next wire locking and cutting.

[0048] Embodiment 2

[0049] This embodiment is further optimized on the basis of the first embodiment, and the same parts as the above technical solution are not repeated here. Figure 1 , Figure 2 , Figure 4 as well as Fig.10 In order to further and better realize the present invention, the following setting method is particularly adopted: a vertical plate 19 is fixedly connected to one side of the upper end of the mounting seat 5, and a positioning plate 21 is supported and slidably connected to the inner surface of the vertical plate 19 through a supporting slider 20, and the supporting slider 20 is vertically slidably connected to the inner surface of the vertical plate 19, and a limiting block 22 is installed on the inner side of the upper end of the positioning plate 21, and a supporting ring 23 for supporting the end of the sleeve roller 18 is installed on the inner surface of the limiting block 22, and the inner ring of the supporting ring 23 is rotatably connected to a force ring 231, and the force ring 231 is rotatably connected to the inner surface of the vertical plate 19. The inner circle recess of 31 is connected with a contact piece 232, and the end of the sleeve roller 18 can be inserted into the force circle 231, so that the sleeve roller 18 can support and limit its end when rotating; the side of the limit block 22 is fixedly connected with a steering rod 24, and the side of the support plate 30 is provided with a right-angle groove 25 for the steering rod 24 to slide, and also includes a horizontal positioning auxiliary mechanism for controlling the steering rod 24 synchronously with the push-pull mechanism. The state of the limit block 22 can be controlled while cutting and locking the wire, so as to facilitate the replacement of the sleeve roller 18;

[0050] The horizontal positioning auxiliary mechanism includes an L-shaped transmission plate 151 fixedly connected to the bottom end of the push plate 141 and slidingly passing through the corresponding support plate 30. The inner surface of the support plate 30 is rotatably connected to a threaded sleeve 153 through a support block. A screw 155 is inserted into the inner thread of the threaded sleeve 153, and the outer end of the screw 155 is fixedly connected to a U-shaped plug plate 156 detachably plugged into the upper end of the steering rod 24. Under the transmission of the horizontal positioning auxiliary mechanism, the U-shaped plug plate 156 can push and pull the steering rod 24, and the steering rod 24 can be separated from the U-shaped plug plate 156 when it moves downward and move upward. When moving, the U-shaped plug plate 156 can be inserted into the connecting groove at the upper end of the steering rod 24 again, and the inner surface of the corresponding support plate 30 is provided with a right-angle slide groove for the steering rod 24 to slide. The lower end of the L-shaped transmission plate 151 is fixedly connected with a rack 152, and the outer side of the threaded sleeve 153 is fixedly sleeved with a gear 154 that meshes with the rack 152 for transmission; the side of the connecting frame 121 is fixedly connected with a sleeve 124, and a transmission plate 125 fixedly connected to the positioning plate 21 is slidably inserted in the sleeve 124. The lifting assembly synchronously controls the position of the positioning plate 21 during the lifting and lowering process.

[0051] In this embodiment, by arranging a limit block 22 and a support ring 23 on the outer side of the rotating shaft 17, the force ring 231 inside the support ring 23 can support and limit the sleeve roller 18 on the outer side of the rotating shaft 17. When cutting, when the push plate 141 moves toward the sleeve roller 18, it will drive the L-shaped transmission plate 151 to move inward, so that the rack 152 and the gear 154 will be meshed and driven, driving the threaded sleeve 153 to rotate. While the threaded sleeve 153 is rotating, it will push the steering rod 24 to move to one side through the U-shaped plug plate 156, thereby driving the limit block 22 and the support ring 23 to separate from the end of the sleeve roller 18; when the knife box 6 and the magnetic control box 27 move downward, they will pass through the connecting frame 121 and the sleeve 1 24. The transmission plate 125 drives the positioning plate 21 to move downward. At this time, the roller 18 can be removed and replaced with a new one. During the return process, the knife box 6 and the magnetic control box 27 will first drive the positioning plate 21 to move upward, and the U-shaped plug plate 156 will be inserted into the groove at the upper end of the steering rod 24. Finally, when the push plate 141 is reset, it will drive the rack 152 to move back and engage with the gear 154 in the reverse direction to drive the screw 155 to move back, so that the force circle 231 is automatically stuck at the end of the new roller 18 again. While cutting the wire, it can not only lock the wire to prevent the wire from rebounding and loosening, but also complete the adjustment of the support ring 23, which is convenient for removing and replacing the roller 18.

[0052] Embodiment 3

[0053] like Figure 1 , Figure 4 , Fig. 9 As shown, the present invention provides an installation method for a glass fiber drawing machine that is convenient for replacing blades. When replacing and installing the blades:

[0054] Step 1: First, turn the bolt 292 to disengage its inner end from the threaded positioning groove, and then remove the blade locking plate 29 to one side;

[0055] Step 2: Take out the old blade to one side. Since the blade slides in the blade taking groove 28 through two pairs of limit sliders 91, the old blade can be taken out safely and quickly after the blade locking plate 29 is removed.

[0056] Step 3: insert a new blade into the blade taking slot 28, and make the two pairs of limit sliders 91 slide in the two pairs of horizontal slide slots 92 respectively. Next, insert the blade locking plate 29 into the blade taking slot 28, position the back of the blade, and the blade can slide to the inner side of the blade box 6 under the magnetic attraction of the blade magnet 26 to complete the shredding.

[0057] Step 4: After the knife locking plate 29 is inserted into the knife taking groove 28 , the bolt 292 is rotated so that its inner end is inserted into the threaded positioning groove, and the knife locking plate 29 is locked.

[0058] When the blade 9 is installed and replaced, no parts are needed to fix it. The blade 9 slides through the inner end of the blade box 6, and its back is positioned by the blade locking plate 29. Under the action of the magnetic attraction of the blade magnet 26, the blade 9 can slide to cut wire. When replacing, unscrew the bolt 292, remove the blade locking plate 29 to one side, take the blade 9 outward, put in a new blade 9, and then fix the blade locking plate 29 in the blade removal groove 28.
