Description

Technical Field

[0001] This utility model belongs to the field of heat exchanger fin processing technology, specifically a heat exchanger fin processing device that is easy to fix. Background Technology

[0002] The basic principle of a heat exchanger is to transfer heat through heat exchange between two fluids at different temperatures. The presence of fins significantly increases the effective heat transfer area of ​​the heat exchanger, allowing heat to be transferred from one side to the other in a shorter time. Compared to bare tubes without fins, finned tubes have a larger heat transfer area, thereby improving the overall heat transfer efficiency of the heat exchanger. Fins can generate a turbulence effect, break the flow boundary layer, reduce thermal resistance, and further enhance the heat transfer effect.

[0003] In the existing technology, when processing heat exchanger fins, it is impossible to rotate the clamped heat exchanger fins. It is necessary to release the clamps and rotate them manually, which wastes a lot of time and reduces production efficiency. Furthermore, when spraying anti-corrosion coating on heat exchanger fins, it is impossible to adjust the angle, which can easily lead to some small parts not being coated properly, thus reducing the service life of the heat exchanger fins. Utility Model Content

[0004] To overcome the above-mentioned defects, this utility model provides a heat exchanger fin processing device that is easy to fix, which solves the problem that in the prior art, when processing heat exchanger fins, it is impossible to rotate the clamped heat exchanger fins, and manual rotation is required after unclamping and fixing, which wastes a lot of time and reduces production efficiency.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a heat exchanger fin processing device for easy fixing, comprising a mounting plate, a support plate one, a support plate two, and a support baffle fixedly connected to the top of the mounting plate, the support plate one and the support plate two being located on opposite sides of the top of the mounting plate, the support baffle being located on one side of the top of the mounting plate, the support plate one and the support plate two being perpendicular to the support baffle, an air pump one being fixedly connected to one side of the support plate one, a telescopic rod one being fixedly connected to the output end of the air pump one, and a drive clamping plate being provided at one end of the telescopic rod one;

[0006] A motor is fixedly connected to one side of the second support plate. A rotating rod is rotatably connected to the second support plate. A rotating clamping plate is fixedly connected to one end of the rotating rod. A rectangular groove is provided on the support baffle. The rectangular groove is located near the top of the support baffle. A threaded rod is rotatably connected to the rectangular groove. An L-shaped slider is threaded onto the threaded rod. A support ring is fixedly connected to the top of the L-shaped slider. A spray pipe is rotatably connected to the support ring. Two limiting blocks are fixedly connected to the top of the support baffle. The two limiting blocks are symmetrically arranged about the spray pipe. A gear rack is slidably connected to the limiting blocks.

[0007] As a further embodiment of this utility model: one end of the rotating rod and the output end of the motor are both fixedly connected to pulleys, and belts are provided on the two pulleys.

[0008] As a further embodiment of this utility model: the telescopic rod is rotatably connected to the drive clamping plate, and the centers of the drive clamping plate and the rotating clamping plate are at the same level.

[0009] As a further embodiment of this utility model: a servo motor is fixedly connected to the top of one side of the support baffle, and gears are fixedly connected to the output end of the servo motor and the end of the threaded rod that passes through the support baffle, and the two gears mesh with each other.

[0010] As a further embodiment of this utility model: the surface of the spray tube is provided with a plurality of uniformly distributed spray nozzles, a drive gear is fixedly connected to the end of the spray tube away from the drive clamping plate, and a feed port is provided at one end of the spray tube.

[0012] Compared with the prior art, the beneficial effects of the present invention are:

[0013] 1. This convenient heat exchanger fin processing device, by setting up a telescopic rod, a motor and a rotating rod, uses an air pump to push the telescopic rod to extend and retract to clamp and fix the heat exchanger fins. Then, the motor is started, and under the action of the belt, it drives the two pulleys to rotate. The rotating rod drives the clamping plate to rotate, which in turn drives the clamped heat exchanger fins to rotate. This avoids manual rotation, saves time and improves production efficiency.

[0014] 2. This convenient heat exchanger fin processing device, by setting a drive gear, a limit block and a gear rack, uses an air pump to drive the telescopic rod to extend and retract, pushing the gear rack to slide within the two limit blocks. Under the meshing action of the drive gear and the gear rack, the spray pipe is rotated, thereby adjusting the spraying angle of the spray nozzle. This avoids some small parts not being sprayed in place, and improves the service life of the heat exchanger fins. Attached Figure Description

[0019] The technical solution of this patent is further described in detail below in conjunction with specific implementation methods.

[0020] like Figure 1-3 As shown, this utility model provides a technical solution: a heat exchanger fin processing device for easy fixing, including a mounting plate 1, a support plate 2, a support plate 3 and a support baffle 12 fixedly connected to the top of the mounting plate 1, a rotating rod 8 rotatably connected to the support plate 3, a rotating clamping plate 9 fixedly connected to one end of the rotating rod 8, a motor 7 fixedly connected to one side of the support plate 3, a pulley 10 fixedly connected to one end of the rotating rod 8 and the output end of the motor 7, and belts 11 provided on the two pulleys 10.

[0021] Support plate 12 and support plate 23 are located on both sides of the top of mounting plate 1, and support baffle 12 is located on one side of the top of mounting plate 1. Support plate 12 and support plate 23 are perpendicular to support baffle 12. Air pump 14 is fixedly connected to one side of support plate 12. Telescopic rod 15 is fixedly connected to the output end of air pump 14. One end of telescopic rod 15 is provided with drive clamping plate 6. Air pump 14 is driven to clamp and fix the heat exchanger fins through the action of telescopic rod 15. Telescopic rod 15 is rotatably connected to drive clamping plate 6. The centers of drive clamping plate 6 and rotating clamping plate 9 are at the same level. Because drive clamping plate 6 and rotating clamping plate 9 are set at the same level, the rotation of heat exchanger fins is avoided.

[0022] A rectangular groove 13 is provided on the support baffle 12. The rectangular groove 13 is located near the top of the support baffle 12. A threaded rod 14 is rotatably connected in the rectangular groove 13. An L-shaped slider 15 is threadedly connected to the threaded rod 14. A servo motor 16 is fixedly connected to the top of one side of the support baffle 12. Gears 17 are fixedly connected to the output end of the servo motor 16 and the end of the threaded rod 14 that passes through the support baffle 12. The two gears 17 mesh with each other. The servo motor 16 needs to frequently rotate forward and backward to drive the L-shaped slider 15 to slide back and forth in the rectangular groove 13. The sliding of the L-shaped slider 15 with the rectangular groove 13 avoids the L-shaped slider 15 from shaking when sliding. The mutual cooperation of the two gears 17 transmits power.

[0023] A support ring 18 is fixedly connected to the top of the L-shaped slider 15. A spray tube 19 is rotatably connected inside the support ring 18. The surface of the spray tube 19 has multiple evenly distributed spray nozzles 20. A drive gear 21 is fixedly connected to the surface of the end of the spray tube 19 away from the drive clamping plate 6. A feed port 26 is provided at one end of the spray tube 19. The feed port 26 is used to connect the anti-corrosion spraying material. The heat exchanger fins are sprayed through the evenly distributed spray nozzles 20 on the spray tube 19. The support ring 18 supports the spray tube 19 so that the spray tube 19 is kept horizontal with the heat exchanger fins.

[0024] Two limiting blocks 22 are fixedly connected to the top of the support baffle 12. The two limiting blocks 22 are symmetrically arranged about the spray pipe 19. A gear rack 23 is slidably connected inside the limiting blocks 22. One end of the gear rack 23 is fixedly connected to a telescopic rod 24. An air pump 25 is fixedly connected to the top of one side of the support baffle 12. One end of the telescopic rod 24 is fixedly connected to the output end of the air pump 25. The meshing of the drive gear 21 and the gear rack 23 can drive the spray pipe 19 to rotate. The symmetrical arrangement of the two limiting blocks 22 serves two purposes: first, to prevent the gear rack 23 from shifting when sliding; and second, to keep the rotation angles of the left and right sides of the spray pipe 19 consistent.

[0025] The working principle of this utility model is as follows: Before use, connect the anti-corrosion spraying material through the feed port 26, then place the heat exchanger fins between the drive clamping plate 6 and the rotating clamping plate 9. Start the air pump 4 to extend and retract the telescopic rod 5, which clamps and fixes the heat exchanger fins through the drive clamping plate 6 and the rotating clamping plate 9. Start the servo motor 16 to drive the two meshing gears 17 to rotate, which in turn drives the threaded rod 14 to rotate, thereby driving the L-shaped slider 15 to reciprocate within the rectangular groove 13. Then start the air pump 25 to extend and retract the telescopic rod 5. The extension and retraction of the second retractor 24 pushes the gear rack 23 to slide back and forth. Under the meshing action of the drive gear 21 and the gear rack 23, the spray pipe 19 is driven to rotate back and forth at a certain angle. The spray nozzle 20 sprays the heat exchanger fins held in the spray. When the L-shaped slider 15 moves from one side of the rectangular groove 13 to the other side, the motor 7 is started to rotate. Through the cooperation of the pulley 10 and the belt 11, the rotating rod 8 is driven to rotate, which in turn drives the heat exchanger fins held by the drive clamping plate 6 and the rotating clamping plate 9 to rotate half a turn before spraying again.

[0026] In the description of this utility model, it should be noted that, unless otherwise expressly specified or limited, the terms "installed," "connected," and "connected" should be understood in a broad sense. For example, they can refer to fixed connections, detachable connections, or integral connections; mechanical connections, electrical connections; direct connections, indirect connections through an intermediate medium, and internal communication between two components. Those skilled in the art will understand the specific meanings of the above terms in this utility model based on specific circumstances.
