[0029] The technologies, methods and equipment known to ordinary technicians in the relevant fields may not be discussed in detail, but in appropriate cases, the technologies, methods and equipment should be regarded as part of the specification. As mentioned in the above background technology, in the production process of the glass tube drawing machine, the stable rotation of the rotating tube with the main shaft under the drive of the main shaft is an important guarantee for ensuring the processing quality of the glass tube drawing machine. For this reason, a clamping mechanism is required to clamp the rotating tube on the main shaft through a sleeve and other connecting parts. However, due to the high pressure of the clamping mechanism, it is easy to cause damage and deformation of the sleeve and other connecting parts, and the sleeve and other connecting parts need to be repaired or replaced, thereby affecting normal production and increasing equipment maintenance and operation costs. Based on this, the inventors of the present application provide a rotating device and a glass tube drawing machine for a glass tube drawing machine in one or more embodiments. The rotating device of the glass tube drawing machine increases the structural strength and bearing pressure of the sleeve by setting a rib plate, avoids the problem of damage and deformation of the sleeve caused by the clamping mechanism when applying a large pressure, ensures normal production and reduces the operation and maintenance costs of the equipment. It is believed that it can solve one or more problems in the prior art.

[0030] In view of the above-mentioned technical problems, the utility model provides a rotating device for a glass tube drawing machine, such as Figure 1 and Figure 2 As shown, it includes: a rotating tube 1, which includes a first end and a second end; a large shaft 2, which includes a front end and a rear end, and the front end is inserted into the rotating tube 1 from the second end and is connected to the first end; a sleeve 3, which includes a cylinder 4, a pressure ring 5 and a rib plate 6, and the cylinder 4 is sleeved on the large shaft 2, and the cylinder 4 includes a pressure-applying end and a pressure-receiving end, and the pressure ring 5 is arranged on the pressure-receiving end and abuts against the second end, one end of the rib plate 6 is connected to the cylinder 4, and the other end is connected to the pressure ring 5 to strengthen the structural strength of the sleeve 3; a clamping mechanism, which is arranged on the large shaft 2 and is connected to the pressure-applying end to apply an extrusion force to the sleeve 3 to clamp the rotating tube 1 on the large shaft 2.

[0031] Specifically, to ensure that the rotating tube 1 can rotate stably with the main shaft 2, the clamping mechanism applies pressure to the pressure-applying end of the sleeve 3, and the sleeve 3 transmits the extrusion force to the pressure ring 5 set on the pressure-receiving end. The pressure ring 5 applies pressure to the rotating tube 1 to press the rotating tube 1 on the main shaft 2. The rib plate 6 can strengthen the connection structure strength of the cylinder 4 and the pressure ring 5 and the bearing pressure of the sleeve 3 to prevent the pressure ring 5 from being deformed and damaged under a pressure of about 500 kilograms and an ambient temperature of more than 1000 degrees. Furthermore, the rib plate 6, the cylinder 4 and the pressure ring 5 need to be connected by full welding to ensure the connection strength.

[0032] Compared with the prior art, the rotating device of a glass tube drawing machine of the present application increases the structural strength and bearing pressure of the sleeve 3 by providing a rib plate 6, thereby avoiding the problem of damage and deformation of the sleeve 3 caused by the clamping mechanism when applying a large pressure, thereby ensuring normal production while reducing the operation and maintenance costs of the equipment.

[0033] In some embodiments, the ribs 6 include a plurality of ribs, and the plurality of ribs 6 are arranged along the circumference of the pressure-bearing end. The structural strength of the sleeve 3 and the bearing pressure of the pressure ring 5 are further ensured by the plurality of ribs 6. Furthermore, the plurality of pressure rings 5 ​​can be arranged at equal intervals along the circumference of the pressure-bearing end to ensure the balance and stability of the pressure system of the sleeve 3.

[0034] In some embodiments, Figure 2 As shown, the rotating device of the glass tube drawing machine also includes a locking mechanism, which includes a threaded hole 7 and a bolt. The threaded hole 7 is opened on the pressure end, and the bolt passes through the threaded hole 7 and abuts on the main shaft 2 to lock the sleeve 3 on the main shaft 2. The sleeve 3 can be locked on the main shaft 2 through the locking mechanism, avoiding the problem of the sleeve 3 shaking and affecting normal production.

[0035] In some embodiments, the locking mechanism includes multiple locking mechanisms, and the multiple locking mechanisms are arranged along the circumference of the pressure end. The multiple locking mechanisms further avoid the problem of the sleeve 3 shaking. Specifically, the multiple locking mechanisms can also be arranged at equal intervals along the circumference of the pressure end.

[0036] In some embodiments, Figure 1 As shown, the clamping mechanism includes a spring 8 and an adjusting nut 9. The spring 8 is sleeved on the main shaft 2, one end of which is connected to the pressure end, and the other end is connected to the adjusting nut 9. The adjusting nut 9 is movably arranged on the main shaft 2 to adjust the clamping force applied by the clamping mechanism to the sleeve 3. The function of the clamping mechanism to apply extrusion force to the sleeve 3 is realized by the spring 8 and the adjusting nut 9. Specifically, the spring 8 must have a certain elastic modulus to ensure that it can generate sufficient extrusion force on the sleeve 3. Furthermore, a spare nut can be provided on the main shaft 2 to prevent the adjusting nut 9 from loosening during the rotation of the main shaft 2. In order to ensure the balance of the extrusion force applied by the spring 8 to the sleeve 3, the spring 8 and the pressure end can be connected together through a connecting plate.

[0037] In some embodiments, Figure 1 As shown, the rotating device of the glass tube drawing machine also includes a gland 10, and the second end is connected to the pressure-receiving end through the gland 10. The gland 10 strengthens the integrity of the connection between the rotating tube 1 and the sleeve 3, ensuring the stability of the force when the sleeve 3 squeezes the rotating tube 1.

[0038] In some embodiments, the rotating device of the glass tube drawing machine further includes a motor, which is connected to the rear end to drive the main shaft 2 to rotate. The main shaft 2 rotates through the drive of the motor, thereby driving the rotating tube 1 to rotate synchronously.

[0039] In some embodiments, Figure 3 As shown, the rotating device of the glass tube drawing machine further includes a support block 11, which is arranged in the rotating tube 1, and one end of the support block 11 is connected to the inner wall of the rotating tube 1, and the other end is abutted against the main shaft 2. The support block 11 further ensures the integrity of the connection between the rotating tube 1 and the main shaft 2, avoiding the problem of rotation shaking during the production process.

[0040] In some embodiments, Figure 1 As shown, the rotating device of the glass tube drawing machine further includes a baffle 12, which is arranged on the sleeve 3. The baffle 12 plays a protective role, preventing the glass liquid on the rotating tube 1 from splashing onto other parts of the glass tube drawing machine during the production process.

[0041] On the other hand, the utility model provides a glass tube drawing machine, including the above-mentioned rotating device of the glass tube drawing machine. The structural strength and bearing pressure of the sleeve 3 are increased by the rib plate 6, the problem of damage and deformation of the pressure ring 5 is avoided, and the maintenance cost of the glass tube drawing machine is saved.

[0042] In summary, compared with the prior art, the present invention provides a rotating device for a glass tube drawing machine and a glass tube drawing machine. The rotating device of the glass tube drawing machine increases the structural strength and bearing pressure of the sleeve 3 by setting a rib plate 6, thereby avoiding the problem of damage and deformation of the sleeve 3 caused by the clamping mechanism when a large pressure is applied, thereby ensuring normal production while reducing the operation and maintenance costs of the equipment; the sleeve 3 can be locked on the main shaft 2 through the locking mechanism, thereby avoiding the problem of the sleeve 3 shaking and affecting normal production.
