The third aspect of the invention provides a glass tube drawing machine, comprising a tube drawing mechanism and the glass tube drawing runway, wherein the tube drawing mechanism pulls a glass tube to be drawn on the glass tube drawing runway along a preset path, the glass tube drawing runway comprises at least one rolling support mechanism arranged along the preset path, and the rolling support mechanism comprises a support part 1 and a rolling assembly 2. The support part 1 comprises a horizontal support frame 11; the rolling assembly 2 is obliquely connected with the supporting frame 11, a supporting space 21 capable of supporting a glass tube to be pulled is formed above the rolling assembly 2, the rolling assembly 2 comprises a shaft lever 22, a rolling piece 23 and a bearing 24, the shaft lever 22 is obliquely connected with the supporting frame 11, the rolling piece 23 is provided with through holes 231 penetrating through two ends so as to be sleeved on the shaft lever 22, the outer edge of the bearing 24 is connected with the inner wall of the through hole 231 in a matched manner, and the inner edge of the bearing 24 is connected with the shaft lever 22 in a matched manner; wherein, the glass tube to be drawn drives the rolling element 23 to drive the bearing 24 to roll relative to the shaft lever 22 in the supporting space 21. In the process of drawing a glass tube, the inclined rolling assembly 2 can provide support for the glass tube to be drawn in the process of contacting the glass tube to be drawn, meanwhile, the supporting space 21 provides a moving channel for the glass tube to be drawn, the outer edge of the bearing 24 is connected with the inner wall of the through hole 231 in a matched manner, the inner edge of the bearing 24 is connected with the shaft lever 22 in a matched manner, the rolling element 23 is connected onto the shaft lever 22 through the bearing 24, and when the rolling element 23 is driven to roll due to friction with the glass tube to be drawn, the rolling element 23 is not directly contacted with the shaft lever 22 to be worn, and the rolling element 23 is directly contacted and rubbed with the shaft lever 22, so that the service life of the rolling element 23 is provided without frequent replacement. By the application of the invention, the problems that in the prior art, the graphite wheel is continuously rubbed by the rotating shaft, the rolling is abnormal after the abrasion degree of the central hole is increased, the rolling support requirement on the glass tube in the tube drawing process can not be normally met, and a large amount of cost is required for frequent replacement are solved.

Thus, various embodiments of the present disclosure have been described in detail. In order to avoid obscuring the concepts of the present disclosure, some details known in the art are not described. How to implement the solutions disclosed herein will be fully apparent to those skilled in the art from the above description.

Although some specific embodiments of the present disclosure have been described in detail by way of example, it should be understood by those skilled in the art that the above examples are for illustration only and are not intended to limit the scope of the present disclosure. It will be understood by those skilled in the art that the foregoing embodiments may be modified and equivalents substituted for elements thereof without departing from the scope and spirit of the disclosure. In particular, the technical features mentioned in the respective embodiments may be combined in any manner as long as there is no structural conflict.
