Description

Technical Field

[0001] This utility model relates to the technical field of spiral quartz tube production equipment, specifically a rotating device for producing spiral quartz tubes. Background Technology

[0002] The current mainstream production process for spiral quartz tubes uses a single-mold thermoforming technology. This involves winding molten quartz glass tubes onto a fixed-size mandrel at a specific temperature, followed by annealing to form a spiral structure. In the production of spiral quartz tubes, the design and functionality of the fixtures directly affect the diversified production and processing efficiency. Traditional fixtures have fixed structures, and the disassembly and installation steps are cumbersome, requiring machine downtime for adjustments, which seriously affects the continuous production rhythm. Each mold system can only produce spiral quartz tubes with a specific outer diameter. Changing product specifications requires a complete replacement of the mold system, and the mold replacement process takes as long as 4-8 hours, which seriously affects production efficiency. Furthermore, small-batch, multi-specification orders lead to a significant increase in mold amortization costs, thus increasing the production cost of spiral quartz tubes.

[0003] Therefore, we propose a rotating device for producing spiral quartz tubes. Utility Model Content

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0016] Please see Figure 1-6This utility model provides a technical solution: a rotating device for producing spiral quartz tubes, characterized in that it includes a base 1, a feeding mechanism 2, a mandrel 3, a slide rail 4, and a rack 5. The slide rail 4 and rack 5 are fixedly installed on the top of the base 1. An L-shaped moving rod 6 is installed on the slide rail 4. Two sets of baffles 41 are provided, with the two sets of baffles 41 respectively installed at both ends of the slide rail 4. A first reduction motor 7 is installed at the lower part of the L-shaped moving rod 6. A gear 8 is installed at the front end of the first reduction motor 7, and the gear 8 cooperates with the rack 5. A transmission shaft 9 is installed in the middle of the L-shaped moving rod 6, passing through the middle of the L-shaped moving rod 6 and movably connected to the L-shaped moving rod 6. A second reduction motor 10 is installed in the middle of the right side of the L-shaped moving rod 6, and the second reduction motor 10 is connected to the right end of the transmission shaft 9. A motor bracket 11 is set at the bottom of the second reduction motor 10, and the motor bracket 11 supports the second reduction motor 10. For support and fixation, the left end of the motor bracket 11 is fixedly connected to the L-shaped moving rod 6. The turntable 12 is fixedly installed on the left end of the transmission shaft 9. Threaded holes 13 are provided on the turntable 12, and multiple sets of threaded holes 13 are provided. The threaded holes 13 are arranged in an arc and gradually approach the center of the turntable 12. The fixing rod 14 is provided on the turntable 12, and the right end of the fixing rod 14 is provided with an external thread that mates with the threaded holes 13. A nut 15 is provided on the fixing rod 14. The fixing rod 14 is installed on the turntable 12 by mates with the threaded holes 13. The threaded holes 13 are arranged in an arc and gradually approach the center of the turntable 12, so that more threaded holes 13 are provided on the turntable 12, allowing for multiple installation options for the fixing rod 14. The fixing rod 14 has multiple dimensions of distance from the center of the turntable 12, so that the circular trajectory of the fixing rod 14 rotating around the mandrel 3 has multiple dimensions. Therefore, this device can produce spiral quartz tubes with different outer diameters. A clamp fixing block 16 is installed on the left end of the fixing rod 14, and a connecting shaft 17 is installed on the left end of the clamp fixing block 16. A first clamping plate 18 is provided on the left end of the connecting shaft 17, and a second clamping plate 19 is provided on the left side of the first clamping plate 18. A bolt 20 is provided between the first clamping plate 18 and the second clamping plate 19, and a nut 21 is provided on the bolt 20. When the first reduction motor 7 is started, the first reduction motor 7 drives the gear 8 to rotate. The gear 8 engages with the rack 5, causing the L-shaped moving rod 6 to move to the left. By rotating the nut 20, the first clamping plate 18 and the second clamping plate 19 are adjusted. The gap between them is clamped by the first clamping plate 18 and the second clamping plate 19 to one end of the quartz tube, causing the first reduction motor 7 to rotate in the opposite direction, causing the L-shaped moving rod 6 to move to the right. At the same time, the second reduction motor 10 is started. The second reduction motor 10 drives the turntable 12 to rotate through the transmission shaft 9. The turntable 12 drives the first clamping plate 18 and the second clamping plate 19 to rotate around the mandrel 3 through the fixing rod 14 and the clamp fixing block 16. This causes the quartz tube, which has been heated by the hydrogen-oxygen flame torch, to rotate around the mandrel 3, so that the quartz tube forms a spiral shape around the mandrel 3.

[0017] The fixture fixing block 16 has a mounting hole 160 in the middle of its right side, a through hole 161 at the top of the mounting hole 160, a limit groove 162 in the middle of the through hole 161, a positioning rod 163 inside the through hole 161, a limit plate 164 on the positioning rod 163, and a spring 165 at the top of the limit plate 164. The top of the fixed rod 14 is provided with a positioning port 141. Pulling the positioning rod 163 upward causes it to move upward and disengage from the positioning port 141, thus releasing the fixation of the fixed rod 14. The moving clamp fixing block 16 allows for the quick disassembly of the first clamping plate 18 and the second clamping plate 19. The replaced clamp fixing block 16 is then installed on the fixed rod 14. The spring 165 pushes the limiting plate 164 to drive the positioning rod 163 downward and lock it in place with the positioning port 141, thus completing the quick replacement of the first clamping plate 18 and the second clamping plate 19. The fixed rod 14 is equipped with the first clamping plate 18 and the second clamping plate 19 for fixing quartz tubes of different diameters. This device produces spiral products of quartz tubes of different diameters.

[0018] The bottom of the L-shaped moving rod 6 is provided with a sliding groove 61 that cooperates with the slide rail 4. The L-shaped moving rod 6 moves on the slide rail, and at the same time, the baffles 41 provided at both ends of the slide rail restrict the movement position of the L-shaped moving rod 6 to prevent the L-shaped moving rod 6 from disengaging from the slide rail 4. A bearing 171 is provided between the connecting shaft 17 and the clamp fixing block 16. When the first clamping plate 18 and the second clamping plate 19 rotate around the mandrel 3 to produce spiral quartz tubes, if the quartz tube is subjected to uneven force after initial cooling and shaping, the clamp fixing block 16 rotates through the bearing 171 to prevent the quartz tube from breaking due to uneven force.

[0019] Two sets of bolts 20 are provided, which pass through the front and rear ends of the first clamping plate 18 and the second clamping plate 19 respectively. Both the first clamping plate 18 and the second clamping plate 19 are provided with through holes that mate with the bolts 20. The bolts 20 pass through the through holes and mate with the nuts 21. Through the mate between the bolts 20 and the nuts 21, the first clamping plate 18 and the second clamping plate 19 fix the quartz tube. At the same time, when the screw nut 21 feels obvious resistance during the tightening process, the screw nut 21 is stopped from being turned to avoid over-tightening of the nut 21, which would cause the quartz tube to break.

[0020] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
