[0003] However, when the existing cutting equipment cuts glass tubes, due to the low toughness of the glass tubes and the inconvenience of heating the cutting parts of the glass tubes by the existing equipment, the glass tubes are prone to breakage during cutting, resulting in an uneven cutting surface of the glass tubes and affecting the quality. Moreover, the existing equipment is not convenient for clamping and limiting the glass tubes, so the glass tubes are prone to move during the cutting process, resulting in poor cutting effects. Content of the Utility Model
[0004] In order to overcome the above disadvantages, the utility model provides a glass tube cutting device for lamp tube manufacturing, which can effectively heat the cutting parts of the glass tubes, make the glass tubes cut more smoothly, and can also effectively clamp and limit the glass tubes, so that the cutting effect of the glass tubes is better.
[0005] A glass tube cutting device for lamp tube manufacturing includes a support base. A limiting ring is fixedly connected to the support base. The limiting ring is provided with a round hole. A motor is fixedly connected to the support base. A dial rod is fixedly connected to the output shaft of the motor. A limiting rotating shaft is rotatably connected to the support base. A torsion spring is connected between the limiting rotating shaft and the support base. A first gear is fixedly connected to the limiting rotating shaft. The dial rod contacts the first gear. A support rod is fixedly connected to the limiting rotating shaft. A cutting machine is fixedly connected to the top end of the support rod. A clamping assembly is arranged on the support base. The clamping assembly is connected to the support rod. When the motor is started, the dial rod rotates. The rotation of the dial rod drives the support rod to rotate intermittently, so that the clamping assembly clamps the glass tube, thereby stably limiting the glass tube.
[0006] Further explanation, the clamping assembly includes a limiting block. The limiting block is fixedly connected to the support base. A second gear is rotatably connected to the limiting block. Two sliding racks are slidably connected to the limiting block. Both of the two sliding racks are meshed with the second gear. Clamping blocks are fixedly connected to the mutually remote ends of the two sliding racks. A limiting shaft is fixedly connected to the bottom end of one of the clamping blocks. An arc-shaped rail is fixedly connected to the support rod. An arc-shaped groove is formed in the arc-shaped rail. The limiting shaft is slidably connected to the arc-shaped groove of the arc-shaped rail.
[0007] Further explanation: The clamping block is made of high-temperature resistant rubber material.
[0008] Further explanation: It further includes a heating block, and the heating block is fixedly connected to the limiting ring.
[0009] Further explanation: It further includes ball bearings, and a plurality of ball bearings are rotatably connected in the round holes of the limiting ring.
[0010] The beneficial effects of the present utility model are as follows: 1. In the present utility model, the motor drives the lever to rotate. The rotation of the lever will intermittently drive the limiting rotating shaft, the support rod and the cutting machine to rotate together through the first gear. The rotation of the cutting machine will contact the glass tube and cut the glass tube. At the same time, after the heating block is powered on, it will heat the cutting part of the glass tube, thereby increasing the toughness of the cutting part of the glass tube, making the glass tube cut more smoothly, and thus improving the quality of the glass tube.
[0011] 2. In the present utility model, the rotation of the support rod drives the arc track to rotate. The rotation of the arc track will push the limiting shaft to move. The movement of the limiting shaft will make the two clamping blocks move towards each other and clamp the glass tube through the second gear, thereby making the glass tube not easy to move, and thus being able to cut the glass tube more stably.

[0022] It further includes a heating block 16, the heating block 16 is connected to the limiting ring 2 by bolts, and the heating block 16 is used for heating the cutting part of the glass tube.
[0023] It further includes a plurality of balls 17, and a plurality of balls 17 are rotatably connected in the round hole of the limiting ring 2.
[0024] First, the staff passes the glass tube through the round hole of the limit ring 2.
