Description

Technical Field

[0001] This utility model belongs to the field of heat exchanger manufacturing technology, and in particular relates to a winding device for heat exchanger manufacturing. Background Technology

[0002] A heat exchanger, also known as a heat exchanger, is a device used to transfer heat from a hot fluid to a cold fluid to meet specified process requirements. It is an industrial application of convective heat transfer and heat conduction. Heat exchangers are common equipment in chemical, petroleum, power, food and many other industrial sectors, and play an important role in production.

[0003] In existing tubular heat exchangers, rubber scrapers are typically used to clean the fin surface during fin winding to ensure better adhesion between the fins and the base tube. However, during cleaning, the prolonged contact and friction between the fins and the rubber scraper generates heat. Excessive heat can damage the rubber scraper, reducing its cleaning effectiveness. The common method for fixing rubber scrapers is with bolts, which requires time-consuming replacements, resulting in low work efficiency. Therefore, we provide a winding device for heat exchanger production. Utility Model Content

[0004] The purpose of this invention is to provide a winding device for heat exchanger production. The device moves a base plate to move a rubber scraper, detaching it from the mounting bracket for easy replacement. This simple and quick operation reduces replacement time and improves work efficiency. Furthermore, the protective cover prevents accidental detachment of the rubber scraper from the mounting bracket due to accidental contact. This invention also solves the problem of existing systems where prolonged contact and friction between the fins and the rubber scraper generates heat, which can damage the scraper and reduce its cleaning effectiveness, necessitating replacement.

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0009] The protective cover and the mounting bracket are obstructed. The bottom of the spring is fixedly connected to the inner wall of the mounting bracket. The rubber scraper is moved by the movement of the base plate, so that it is detached from the mounting bracket. Then the rubber scraper can be replaced. The operation is simple and the rubber scraper can be replaced quickly, reducing replacement time and improving work efficiency. The protective cover can also prevent the rubber scraper from accidentally detaching from the mounting bracket due to accidental contact.

[0037] Please see Figures 1-5 As shown, this utility model is a winding device for producing heat exchangers, including a winding mechanism 1, which is used to wind the heat exchanger.

The rubber scraper 222 can then be replaced. The operation is simple, allowing for quick replacement of the rubber scraper 222, reducing replacement time and improving work efficiency. Furthermore, the protective covers 223 prevent accidental detachment of the rubber scraper 222 from the mounting bracket 221 due to accidental contact.

[0040] The winding mechanism 1 includes a power assembly 11 for providing power for winding; and

[0041] Rotating component 12 is located inside power component 11 and is used to drive the fins to move. After the power component 11 is started, it drives the rotating component 12 to rotate and begin to wind the fins.

[0044] The power assembly 11 includes a processing table 111, which includes a motor 112 fixedly connected to the bottom of the processing table 111. The output end of the motor 112 on the right side is fixedly connected to a threaded rod 121 via a coupling. A pulley 113 is fixedly connected to the outer surface of the threaded rod 121.

[0045] The rotating assembly 12 includes a support platform rotatably connected to the top of the processing table 111. There are two support platforms.

A limit rod 123 is fixedly connected to the side of the two support platforms that are close to each other. The left side of the support platform is fixedly connected to the inner wall of the pulley 115. A base tube 3 is fixedly connected inside the triangular chuck 122. The outer surface of the base tube 3 is rotatably connected to the inner wall of the support platform on the right side.

[0046] The adjusting assembly 21 includes a guide plate 211 slidably connected to the outer surface of the limiting rod 123. The inner wall of the guide plate 211 is threadedly connected to the outer surface of the threaded rod 121. A support frame 212 is fixedly connected to the top of the guide plate 211. A guide wheel 213 contacts the left side of the support frame 212. An adjusting bolt 214 is fixedly connected to the inner wall of the guide wheel 213. The inner wall of the support frame 212 is rotatably connected to the outer surface of the base tube 3. The support frame 212 is viewed from the right side of the adjusting bolt 214. The outer surface of the adjusting bolt 214 is adapted to the threaded hole inside the support frame 212. The base tube 3 and the fins are clamped by the triangular clamp 122. The guide wheel 213 is moved to the left by rotating the adjusting bolt 214. Then, the fins are moved by moving the guide wheel 213, so as to avoid the fins from shifting or tilting when winding the fins.

[0047] The locking assembly 23 includes a pressing block 231 slidably connected to the left and right sides of the mounting bracket 221. A limit rod 232 is slidably connected to the inner wall of the pressing block 231. One end of the limit rod 232 away from the pressing block 231 is fixedly connected to the inner wall of the mounting bracket 221. A spring 233 is sleeved on the outer surface of the limit rod 232. The right side of the spring 233 is fixedly connected to the inner wall of the mounting bracket 221. The outer surface of the pressing block 231 is engaged with the inner wall of the base plate 224.

[0048] A specific application of this embodiment is as follows: In use, the base tube 3 is first installed from right to left, passing through the support frame 212 and extending into the triangular clamp 122. Then, the fins are passed through the mounting frame 221 and the guide wheel 213, so that the fins contact the inner wall of the adjusting bolt 214 of the rubber scraper 222, and the fins are wrapped around the surface of the base tube 3. Then, the base tube 3 and the fins are clamped by the triangular clamp 122. Then, the adjusting bolt 214 is rotated, and the rotation of the adjusting bolt 214 pulls the guide wheel 213 to move to the left. Then, the movement of the guide wheel 213 drives the fins. To prevent fin misalignment or skew during fin winding, the motor 112 is started after adjustment. The motor 112 drives the threaded rod 121 to rotate, which in turn moves the guide plate 211 to the right. Simultaneously, the rotation of the threaded rod 121 drives the pulley 113 to rotate, which in turn drives the pulley 115 via belt 114. The pulley 115 then drives the triangular chuck 122, which in turn drives the base... The tube 3 and fins rotate, causing the fins to wrap around the surface of the base tube 3. This wrapping process continuously pulls the fins, which are then cleaned by a rubber scraper 222 to remove impurities and ensure better adhesion to the base tube 3. However, prolonged friction between the scraper and the fins can damage the scraper, reducing its effectiveness. At this point, the protective cover 223 is pushed upwards, exposing the extrusion block 231. The extrusion block 231 is then pushed inwards, further compressing... When block 231 moves inward, it will release the lock on base plate 224 and compress spring 233. After base plate 224 is released from lock, spring 225 will rebound and push base plate 224 upward. Then, the movement of base plate 224 will drive rubber scraper 222 to move, causing it to detach from mounting bracket 221. Rubber scraper 222 can then be replaced. The operation is simple and the rubber scraper 222 can be replaced quickly, reducing replacement time and improving work efficiency. In addition, the protective cover 223 can prevent the rubber scraper 222 from accidentally detaching from mounting bracket 221 due to accidental contact.
