Description

Technical Field

[0001] This utility model relates to the technical field of heat exchanger tube winding equipment, specifically a tube winding device for winding a wound tube heat exchanger. Background Technology

[0002] Spiral-tube heat exchangers offer unparalleled advantages over conventional shell-and-tube heat exchangers. They boast a wide applicable temperature range, adaptability to thermal shock, self-relief of thermal stress, and high compactness. Their unique structure allows for fully developed flow fields with no dead zones. Most notably, by incorporating multiple tubes (single tube in the shell side), they can simultaneously exchange heat from multiple fluid streams within a single unit. The production of spiral-tube heat exchangers requires a winding process, necessitating specialized winding equipment for this purpose.

[0003] Patent CN222679221U discloses a winding device for winding tube heat exchangers. The device consists of a threaded rod, a limiting block, a knob, a connecting plate, a second sleeve, and a first lead screw. Rotating the knob moves it along the threaded rod, which in turn moves the limiting block. As the limiting block moves, it causes the connecting plate to move along the first lead screw, thus rotating the second sleeve. This allows for easy adjustment of the position of the second sleeve and the limiting block, and facilitates control of the winding height.

[0004] However, the equipment still has some shortcomings in actual use. On the one hand, the top of the tube to be wound lacks a fixing structure. During the winding process, the tube is prone to instability such as shaking and displacement due to uneven force or external interference. This directly affects the winding accuracy and quality, and may lead to problems such as inconsistent winding tightness and irregular shape, which in turn affects the subsequent assembly and performance of the heat exchanger. On the other hand, the device requires manual rotation of the handle to drive the clamping plate to tighten the tube to be wound. This manual operation method is not only labor-intensive but also slow, greatly limiting the improvement of processing efficiency.

[0005] Based on this, a winding device for winding tube heat exchangers is now provided, which can eliminate the drawbacks of existing devices. Utility Model Content

[0024] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments.

[0025] In one embodiment, such as Figure 1As shown, a tube winding device for winding a tube-type heat exchanger includes a base 100, two symmetrical support plates 101 on the base 100, an operating table 102 on the support plates 101, a rotating seat 200 with an automatic clamping mechanism rotatably mounted on the operating table 102, a first drive assembly 300 at the lower end of the rotating seat 200, a stabilizing frame 400 on one side of the rotating seat 200, and a guide tube assembly 500 on the stabilizing frame 400. In use, the tube to be wound is installed on the rotating seat 200, the bottom end of the tube to be wound is fixed by the automatic clamping mechanism, the top end of the tube to be wound is fixed by the stabilizing frame 400, and then the tube is passed through the guide tube assembly 500 and fixed on the tube to be wound. Then, the rotating seat 200 is driven to rotate by the first drive assembly 300 to start the winding process of the tube to be wound.

[0026] In one embodiment, such as Figure 3 As shown, the top of the rotating seat 200 is provided with a first sliding groove 201, and the first sliding groove 201 is provided with a first limiting groove 202. The middle position of the rotating seat 200 is provided with a shaft 213 for installing the tube to be wound. The shaft 213 plays a positioning role for the tube to be wound, ensuring that the tube to be wound can be stably installed on the rotating seat 200 during the winding process. The automatic clamping mechanism is slidably installed in the first sliding groove 201. The automatic clamping mechanism can fix and clamp the lower end of the tube to be wound, so that the tube to be wound can rotate together with the rotating seat 200.

[0027] In one embodiment, such as Figure 3 As shown, the automatic clamping mechanism includes a clamping block 203 disposed on the upper end of the rotating seat 200. The clamping block 203 has anti-slip teeth 204 on one side, which can increase the friction between the clamping block 203 and the tube to be wound, prevent the tube to be wound from sliding during the winding process, and ensure the stability of the winding. The lower end of the clamping block 203 is provided with a guide block 205, which is slidably installed in the first slide groove 201. The guide block 205 is provided with first limiting blocks 206 on both sides, which are slidably installed in the first limiting groove 202. The lower end of the guide block 205 is provided with a drive column 207, and the lower end of the drive column 207 is provided with a second drive assembly. The second drive assembly drives the drive column 207, the guide block 205 and the clamping block 203 to move together along the first slide groove 201 to realize the automatic clamping and loosening of the tube to be wound.

[0028] In one embodiment, such as Figure 3As shown, the second drive assembly includes a circular plate 208 rotatably mounted in a rotating seat 200. The circular plate 208 has an arc-shaped groove 209. The lower end of the drive column 207 is slidably mounted in the arc-shaped groove 209. The lower end of the circular plate 208 is provided with a worm gear 210. A worm 211 is meshed with one side of the worm gear 210. A first motor 212 is provided at one end of the worm 211. When the first motor 212 starts, it drives the worm 211 to rotate. The worm 211 meshes with the worm gear 210, causing the circular plate 208 to rotate. When the circular plate 208 rotates, the arc-shaped groove 209 drives the drive column 207 to perform a circular motion. At the same time, since the drive column 207 slides in the first sliding groove 201, the circular motion is converted into linear motion. This causes the drive column 207, guide block 205, and clamping block 203 to move together along the first sliding groove 201 to achieve automatic clamping and loosening of the pipe to be wound.

[0029] In one embodiment, such as Figure 2 As shown, the first drive assembly 300 includes a second motor 301 mounted on the base 100. The output end of the second motor 301 is provided with a rotating shaft 302. The upper end of the rotating shaft 302 is connected to the rotating seat 200. A first pulley 303 is provided on the rotating shaft 302. When the second motor 301 is working, it drives the rotating shaft 302 to rotate, thereby driving the rotating seat 200 and then driving the pipe to be wound to rotate.

[0030] In one embodiment, such as Figure 2 As shown, the stabilizer 400 includes a vertical plate 401 fixed to one side of the operating table 102. A horizontal plate 402 is hinged to the top of the vertical plate 401. A vertical rod 403 is rotatably mounted on one end of the horizontal plate 402. A knob 404 is provided at the top of the vertical rod 403. A conical seat 405 is provided at the lower end of the vertical rod 403. A connecting seat 406 is provided at the bottom end of the conical seat 405. The connecting seat 406 is threadedly connected to the shaft 213. In use, by rotating the knob 404, the connecting seat 406 is threadedly connected to the shaft 213. At the same time, the conical seat 405 is pressed against the upper end of the tube to be wound, thereby preventing the tube to be wound from shaking, shifting or other unstable phenomena during the winding process.

[0031] In one embodiment, such as Figure 2As shown, the conduit assembly 500 includes a second slide groove 501 disposed on a vertical plate 401. A second limiting groove 502 is provided on one side of the second slide groove 501. A conduit seat 503 is slidably installed in the second slide groove 501. The conduit seat 503 is provided with a through hole 504 for installing a winding tube. A second limiting block 505 is provided on one side of the conduit seat 503. A reciprocating screw 506 is threadedly connected to the conduit seat 503. A second pulley 507 is provided at the lower end of the reciprocating screw 506. In use, the winding tube passes through the through hole 504. During the winding process of the tube to be wound, the reciprocating screw 506 rotates, causing the reciprocating screw 506 to move upward along the second slide groove 501, driving the winding tube to move upward synchronously, so that the winding tube can be evenly wound around the outside of the tube to be wound.

[0032] In one embodiment, such as Figure 2 As shown, the second limiting block 505 is slidably installed in the second limiting groove 502. The second pulley 507 is connected to the first pulley 303 through a belt ring 508. When the first driving assembly 300 drives the rotating seat 200 to rotate, the second pulley 507 is driven to rotate through the belt ring 508, which in turn causes the reciprocating screw 506 to rotate. The reciprocating screw 506 is threadedly connected to the guide seat 503, thereby driving the guide seat 503 to move along the second sliding groove 501.

[0033] The above embodiment discloses a tube winding device for winding a tube-type heat exchanger. In use, the tube to be wound is first installed on the shaft 213. Then, the first motor 212 is started, driving the worm gear 211 to rotate. The worm gear 211 meshes with the worm wheel 210, causing the circular plate 208 to rotate. When the circular plate 208 rotates, the arc-shaped groove 209 drives the drive column 207 to perform circular motion. Simultaneously, because the drive column 207 slides within the first sliding groove 201, the circular motion is converted into linear motion. This causes the drive column 207, guide block 205, and clamping block 203 to move together along the first sliding groove 201, achieving automatic clamping of the tube to be wound. Then, by rotating the knob 404, the connecting seat 406 and the shaft... The rod 213 is threaded, and the tapered seat 405 is pressed against the upper end of the tube to be wound. Then the tube is passed through the through hole 504 and fixed to the lower end of the tube to be wound. Next, the second motor 301 is started to drive the rotating seat 200 to rotate the tube to be wound and perform the winding process. At the same time, when the first drive assembly 300 drives the rotating seat 200 to rotate, the second pulley 507 is driven to rotate through the belt ring 508, which in turn causes the reciprocating screw 506 to rotate. The reciprocating screw 506 is threadedly connected to the guide seat 503, thereby driving the guide seat 503 to move upward along the second slide groove 501, driving the tube to move upward synchronously, so that the tube can be evenly wound on the outside of the tube to be wound.

[0034] The above description is merely a specific embodiment of this application, but the scope of protection of this application is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this application should be included within the scope of protection of this application. Therefore, the scope of protection of this application should be determined by the scope of the claims.
