The two scraping mechanisms 56 on the opposite surfaces of the two L-shaped hanging plates 55 are respectively located on the opposite back sides of the upper and lower tube pulling rotating wheels 11, and the upper and lower sides of the horizontal parts of the two L-shaped hanging plates 55 are overlapped with the upper and lower sides of the inner wall of the slideway 52 respectively.

[0024] When drawing a glass tube, it is necessary to place the glass tube from the feeding hole 4 opened on the unloading top plate 3 into the gap between the tube drawing rotating wheels 11 on the left and right sides. With the help of the tube drawing rotating wheels 11 rotating in opposite directions on the left and right sides, the glass tube can be gradually squeezed and stretched downward. With the help of the height formed by the base bracket 2, it is convenient to finally remove the drawn glass tube. During processing, the positive and negative threaded rods 53 in the slide groove 52 opened on the long plate 51 can be driven to rotate by rotating the rotating handle 54. The threaded walls of the positive and negative threaded rods 53 with opposite threads on the left and right sides can be used to drive the two L-shaped hanging plates 55 to move closer to each other toward the tube drawing rotating wheel 11 until one end of the cleaning inclined plate 563 included in the scraping mechanism 56 is in contact with the outer wall of the tube drawing rotating wheel 11, and at the same time, impurities attached to the outer walls of the four tube drawing rotating wheels 11 are scraped off. After the cleaning inclined plate 563 cleans the tube drawing rotating wheel 11 each time, the positive and negative threaded rods 53 can be reversed by reversing the rotating handle 54, so that the two L-shaped hanging plates 55 drive the scraping mechanism 56 to gradually move away from the tube drawing rotating wheel 11.

[0025] like Figure 3 , Figure 4 As shown, the four scraping mechanisms 56 each include a fixed plate 561, a groove 562 is provided on the side of the fixed plate 561 close to the tube-pulling rotating wheel 11, a cleaning inclined plate 563 is movably connected below the side of the fixed plate 561 close to the tube-pulling rotating wheel 11, the side of the cleaning inclined plate 563 away from the fixed plate 561 overlaps the outer wall of the tube-pulling rotating wheel 11, a spring groove 564 is provided on the side of the cleaning inclined plate 563 close to the fixed plate 561, and four connecting springs 565 are evenly fixedly installed on the inner wall of the spring groove 564 away from the fixed plate 561. The four connecting springs 565 The other end of each of the self-cleaning box 57 is fixedly connected to the inner wall of the groove 562 near the cleaning inclined plate 563. A striking groove 571 penetrating the inner cavity is provided at the bottom of the self-cleaning box 57. The striking groove 571 is located above the cleaning inclined plate 563. A motor 572 is fixedly installed on the front side of the inner wall of the self-cleaning box 57. Four connecting rods 573 are fixedly installed in a circular array on the output shaft of the motor 572. The other ends of the four connecting rods 573 are fixedly installed with striking rubber balls 574. The four striking rubber balls 574 use the rotation of the output shaft of the motor 572 to knock on the top of the cleaning inclined plate 563 one by one.

[0026] When the cleaning inclined plate 563 is cleaned and away from the tube pulling rotating wheel 11, the motor 572 in the four self-cleaning boxes 57 is started to drive the striking rubber balls 574 at the other end of the four connecting rods 573 on the outer wall of the output shaft of the motor 572 to pass through the striking groove 571 to repeatedly strike the cleaning inclined plate 563, so that the cleaning inclined plate 563 is connected with the four connecting springs 565 in the spring groove 564 and the inner wall of the groove 562, and repeatedly vibrates at a high frequency on one side of the fixed plate 561, so that the debris attached to the cleaning inclined plate 563 is promptly shaken off and collected in the debris collection box 553.

[0027] like Figure 5 As shown, two T-shaped clamping grooves 551 are provided on the opposite surfaces of the two L-shaped hanging plates 55, and a T-shaped clamping plate 552 is clamped on the inner wall of the T-shaped clamping groove 551. A debris collection box 553 is fixedly installed on the side of the T-shaped clamping plate 552 close to the tube pulling rotating wheel 11, and the debris collection box 553 is located below the cleaning inclined plate 563. A threaded hole 554 is provided on the side of the T-shaped clamping plate 552 away from the debris collection box 553. Two threaded through holes 555 are provided on the opposite back surfaces of the two L-shaped hanging plates 55. After the T-shaped clamping plate 552 is clamped with the T-shaped clamping groove 551, the threaded hole 554 and the threaded through hole 555 are mutually penetrated, and a threaded rod 556 is threadedly installed in the inner cavity of the threaded through hole 555. The end of the threaded rod 556 close to the T-shaped clamping plate 552 is threadedly connected to the threaded hole 554, and the end of the threaded rod 556 away from the T-shaped clamping plate 552 is fixedly installed with a disassembly knob 557.

[0028] The scraped debris will fall into the debris collection box 553 below the cleaning inclined plate 563.

The entire debris collection box 553 can be directly pulled out from the T-shaped clamping groove 551 using the T-shaped clamping plate 552, which is convenient for cleaning debris. During installation, only the T-shaped clamping plate 552 needs to be aligned with the T-shaped clamping groove 551 and pushed to the bottom, and the disassembly and assembly knob 557 can be rotated again to drive the threaded rod 556 to pass through the threaded through hole 555 and install it with the threaded hole 554 to tighten it.

[0029] The following is a detailed description of the working principle of the automatic glass tube drawing machine.

[0030] like Figure 1-5As shown, when drawing a glass tube, it is necessary to put the glass tube from the feeding hole 4 opened on the unloading top plate 3 downward into the gap between the tube drawing rotating wheels 11 on the left and right sides. With the help of the tube drawing rotating wheels 11 rotating in opposite directions on the left and right sides, the glass tube can be gradually squeezed and stretched downward. With the help of the height formed by the base bracket 2, it is convenient to finally remove the drawn glass tube. During processing, the positive and negative threaded rods 53 in the slide groove 52 opened on the long plate 51 can be driven to rotate by rotating the rotating handle 54. The threaded walls of the positive and negative threaded rods 53 with opposite threads on the left and right sides can be used to drive the two L-shaped hanging plates 55 to move closer to each other and toward the tube drawing rotating wheels 11 until one end of the cleaning inclined plate 563 included in the scraping mechanism 56 is in contact with the outer wall of the tube drawing rotating wheel 11, and at the same time, the impurities attached to the outer walls of the four tube drawing rotating wheels 11 are scraped off, and the scraped debris will fall into the debris collection box 553 below the cleaning inclined plate 563. When the impurities in the debris collection box 553 need to be cleaned, the disassembly knob 557 can be directly rotated to drive the thread The rod 556 is rotated to move out of the threaded hole 554 until the limit of the T-shaped clamping plate 552 is released, so that the entire debris collection box 553 can be directly drawn out from the T-shaped clamping groove 551 by using the T-shaped clamping plate 552, which is convenient for cleaning debris. After each cleaning of the inclined plate 563 to clean the tube-pulling rotating wheel 11, the forward and reverse threaded rods 53 can be reversed by reversing the rotating handle 54, so that the two L-shaped hanging plates 55 drive the scraping mechanism 56 to gradually move away from the tube-pulling rotating wheel 11, and then the scraping mechanism 56 can be started again. By driving the motor 572 in the four self-cleaning boxes 57, the striking rubber balls 574 at the other end of the four connecting rods 573 on the outer wall of the output shaft of the motor 572 can be driven to pass through the striking groove 571 to repeatedly strike the cleaning inclined plate 563, so that the cleaning inclined plate 563 is connected with the four connecting springs 565 in the spring groove 564 and the inner wall of the groove 562, and repeatedly vibrates at a high frequency on one side of the fixed plate 561, so that the debris attached to the cleaning inclined plate 563 is promptly shaken off and collected in the debris collection box 553.

[0031] The above generally describes the present invention in detail, but it is obvious to a person skilled in the art that some modifications or improvements can be made to the present invention. Therefore, modifications or improvements that do not depart from the spirit of the present invention are within the scope of protection of the present invention.
