By setting the push plate 26, when using the wire drawing furnace to perform heat treatment wire drawing on glass fragments, the glass fragments can be placed inside the groove box 21. By adjusting the operating parameters of the motor 22 through the control box on one side of the machine body 1, the motor 22 is operated at regular intervals to drive the first screw 23 to rotate, so that the slide bar 25 moves a certain distance in the direction of the guide plate 27 on the outer surface of the first screw 23 and the inner wall of the slide groove 24. The glass fragments inside the groove box 21 are pushed by the push plate 26 in the direction of the guide plate 27 and pass through the surface of the guide plate 27 and enter the inside of the melting box 5 for processing. By setting the feeding device 2, by adding glass fragments into the groove box 21 and adjusting the operating parameters of the motor 22, the motor 22 is operated to drive the first screw 23 to rotate to control the regular movement of the push plate 26 to push the glass fragments inside the groove box 21 into the inside of the melting box 5, so that the inside of the melting box 5 can be regularly added with glass fragments, without the need to add glass fragments manually, reducing the cost when using the wire drawing furnace and improving the stability of the wire drawing furnace during operation.
[0029] Refer to Figures 1-4As shown, in this embodiment: an auxiliary rod 28 is fixedly connected to one side of the push plate 26, the top of the auxiliary rod 28 is an inclined surface, and the bottom end of the auxiliary rod 28 slides on the bottom end of the inner wall of the groove box 21. When the push plate 26 moves to push out the glass fragments inside the groove box 21, the auxiliary rod 28 can improve the pushing effect of the push plate 26, so that the glass fragments are not easily stuck between the bottom end of the push plate 26 and the bottom end of the inner wall of the groove box 21. A positioning ring 29 is fixedly connected to one side of the outer surface of the groove box 21, and the end of the first screw 23 away from the motor 22 rotates on the inner wall of the positioning ring 29. By setting the positioning ring 29, the angle between the end of the first screw 23 away from the motor 22 and the end close to the motor 22 can be further limited, thereby improving the stability of the first screw 23 when rotating.
[0030] Reference Figures 1-4 As shown, in this embodiment: a guide groove 210 is provided on the outer surface of the guide plate 27, and the guide groove 210 is a tapered groove. The inner wall width of the guide groove 210 away from the end of the slot box 21 is smaller than the inner wall width close to the end of the slot box 21. By setting the tapered guide groove 210, the glass fragments will be concentrated in the middle position of the guide plate 27 when moving through the surface of the guide plate 27, and are not easy to fall from the two sides of the guide plate 27. One end of the sliding rod 25 is fixedly connected to a positioning rod 211, and one side of the positioning rod 211 slides on one side of the slot box 21. When the first screw 23 rotates to control the movement of the sliding rod 25, one side of the positioning rod 211 will slide on one side of the outer surface of the slot box 21, thereby further limiting the angle between the sliding rod 25 and the slot box 21, increasing the stability of the sliding rod 25 when moving, and avoiding shaking of the sliding rod 25 when moving as much as possible.
[0031] Reference Figure 1 , Figure 2 and Figure 4 As shown, in the present embodiment: an adjusting device 3 is provided on the outer surface of the guide plate 27, the adjusting device 3 includes a sliding plate 31, the outer surface of the sliding plate 31 is slidably connected to the bottom end of the inner wall of the guide plate 27, the bottom end of the sliding plate 31 is fixedly connected to the second screw 32, and one side of the bottom end of the trough box 21 is rotatably connected to a threaded barrel 33, the inner wall of the threaded barrel 33 is threadedly connected to the outer surface of the second screw 32. When using the feeding device 2, the threaded barrel 33 can be rotated at the bottom end of the trough box 21 to make the second screw 32 move on the inner wall of the threaded barrel 33, driving the sliding plate 31 to slide on the inner wall of the guide plate 27 to adjust the length of the sliding plate 31 extending out of the guide plate 27. By changing the total length of the guide plate 27 and the sliding plate 31, the flexibility of the feeding device 2 when in use is improved.
[0032] Reference Figure 1 , Figure 2 and Figure 4As shown, in the present embodiment: a plurality of ridges 34 are fixedly connected to the outer surface of the threaded barrel 33, and the members of the ridges 34 are distributed around the outer surface of the threaded barrel 33. Holding the ridges 34 on the outer surface of the threaded barrel 33 can increase the friction between the hand and the outer surface of the threaded barrel 33 when in contact, making it more convenient and less likely to slip when rotating the threaded barrel 33. A positioning block 35 is fixedly connected to the bottom end of the guide plate 27, and the end of the threaded barrel 33 away from the groove box 21 rotates on the inner wall of the positioning block 35. When the threaded barrel 33 is rotated to adjust the position of the sliding plate 31, one end of the threaded barrel 33 will rotate on the inner wall of the positioning block 35, further limiting the angle between the threaded barrel 33 and the groove box 21, and avoiding as much as possible the deviation of the angle of the threaded barrel 33 when the threaded barrel 33 is rotated.
[0033] Working principle: When using the wire drawing furnace to heat-treat glass fragments, first rotate the threaded barrel 33 at the bottom of the groove box 21 to control the second screw 32 to move on the inner wall of the threaded barrel 33, drive the sliding plate 31 to slide on the inner wall of the guide plate 27, and adjust the length of the sliding plate 31 extending out of the guide plate 27. Then, add a large amount of glass fragments into the groove box 21, and control the operation of the electric heating tube 4 through the control box on one side of the body 1. The melting box 5 is heated by the electric heating tube 4, and the operating parameters of the motor 22 are adjusted so that the motor 22 operates at a certain time to drive the first screw 23 to rotate, so that the sliding rod 25 is in the first screw 23. The outer surface and the inner wall of the slide groove 24 move a certain distance in the direction of the guide plate 27, and the glass fragments inside the trough box 21 are pushed in the direction of the guide plate 27 by the push plate 26 through the guide groove 210 on the surface of the guide plate 27 and the surface of the sliding plate 31 into the interior of the melting box 5. After the glass fragments enter the interior of the melting box 5, the glass fragments are melted into liquid by high temperature, and then the liquid glass flows out through the through hole at the bottom of the inner wall of the melting box 5 for drawing. After the glass fragments inside the trough box 21 are used up, the motor 22 is operated again to drive the first screw 23 to rotate and control the push plate 26 to move in the direction of the motor 22, so as to add glass fragments to the interior of the trough box 21 again.
