Description

Technical Field

[0001] The present invention relates to the technical field of heat exchanger processing, and in particular to a production line for heat exchanger processing. Background Art

[0002] When processing existing heat exchangers, they are generally assembled bit by bit on an assembly line. After assembly is completed, the heat exchanger is removed from the assembly line for packaging, or is packaged directly on the assembly line. However, for some larger heat exchangers, they are generally packaged in a set manner, that is, the packaging box is controlled to be placed on the outside of the heat exchanger, and then the whole is turned over. When the packaging box is turned over, since the heat exchanger inside the packaging box is large and heavy, it may cause marks on the packaging box, resulting in a lower aesthetics of the packaging box. Therefore, a production line for heat exchanger processing is needed to solve the above problem. Summary of the Invention

[0039] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0040] Example 1

[0041] like Figure 1-7As shown, the present invention provides a technical solution: a production line for heat exchanger processing, comprising a first transmission mechanism 1 and a blanking mechanism 2, a second transmission mechanism 3 is provided on one side of the first transmission mechanism 1, a support frame 4 is provided on the top of the second transmission mechanism 3, a packaging box 5 is provided on the top of the support frame 4, the blanking mechanism 2 comprises a shell 21, a fixing groove 22 is provided at the bottom of the shell 21, two rotating plates 23 are rotatably connected to the inner wall of the fixing groove 22, a gear 24 is fixedly connected to one side of the two rotating plates 23, a rack 25 is provided on the outer surface of the gear 24, a fixing mechanism 26 is provided on the outer surface of the rack 25, a lifting mechanism 29 is provided at the bottom of the fixing mechanism 26, a magnetic body 210 is provided at the bottom of the lifting mechanism 29, and the outer surface of the magnetic body 210 is fixedly connected to the mounting plate 211. Two slide grooves 27 are provided at the bottom of the shell 21. The inner walls of the two slide grooves 27 are slidably connected with slide plates 28. The slide grooves 27 and the slide plates 28 can limit the lifting mechanism 29 and prevent the gear 24 from contacting the fixing mechanism 26. One side of the shell 21 is fixedly connected to a base 212. A stepper motor 213 is fixedly provided on the top of the base 212. One end of the stepper motor 213 is connected to a shaft, and one end of the shaft rotates and passes through the inside of the fixing groove 22. One end of the shaft is fixedly connected to one side of the rotating plate 23. The two gears 24 are rotatably connected through a rack 25. The outer surface of the rack 25 is slidably connected to the inner wall of the rotating plate 23. The rack 25 is slidably connected to the inner wall of the rotating plate 23, so that the rack 25 can be limited to increase the structural stability of the equipment.

[0042] In this embodiment, during use, the first transmission mechanism 1 transmits the heat exchanger. After the heat exchanger is assembled, the unloading mechanism 2 removes the heat exchanger from the first transmission mechanism 1. Specifically, the lifting mechanism 29 controls the magnetic body 210 to descend. After the magnetic body 210 descends to the top of the heat exchanger, the magnetic body 210 is turned on. The magnetic body 210 is an electromagnet, which is a device that can generate electromagnetic energy when energized. The magnetic body 210 is then fixed to the top of the heat exchanger. The lifting mechanism 29 controls the magnetic body 210 to move upward. The movement of the magnetic body 210 drives the heat exchanger to move. The stepper motor 213 is then turned on. The stepper motor 213 drives the rotating plate 23 to rotate through the shaft. The rotation of the rotating plate 23 drives one of the gears 24 to rotate, and the rack 25 is meshed with the gear 24. Therefore, the rotation of one of the gears 24 will drive the rotation of the other gear 24, and at the same time, the rack 25 rotates between the gears 24. At this time, the rack 25 drives the lifting mechanism 29 to move through the fixing mechanism 26, and the movement of the lifting mechanism 29 drives the magnetic body 210 to move, and the movement of the magnetic body 210 drives the heat exchanger to move. At this time, under the action of the stepping motor 213, the heat exchanger is moved to the second transmission mechanism 3. When the heat exchanger reaches the top of the packaging box 5 above the second transmission mechanism 3, the lifting mechanism 29 controls the magnetic body 210 to move downward. When the bottom of the heat exchanger contacts the bottom surface of the packaging box 5, the magnetic body 210 can be closed, and then the other mechanisms can be restored to their original positions. At this time, the packaging box 5 above the second transmission mechanism 3 does not need to be flipped over to be packaged, thereby avoiding the packaging box 5 having strangle marks.

[0043] Example 2

[0044] like Figure 4-5As shown, the lifting mechanism 29 includes a fixed plate 291, and a plurality of hydraulic rods 292 are provided on the top of the fixed plate 291. The bottom ends of the plurality of hydraulic rods 292 all slide through the bottom of the fixed plate 291, and a support plate 293 is fixedly connected between the outer surfaces of the plurality of hydraulic rods 292. The top of the fixed plate 291 is fixedly connected to the bottom of the slide plate 28, and the plurality of hydraulic rods 292 can be fixed by the support plate 293 to increase the structural stability of the equipment. A support plate 2911 is fixedly connected between the bottom ends of the plurality of hydraulic rods 292, and a mounting hole is provided on the top of the support plate 2911, and the inner wall of the mounting hole is slidably connected to the outer surface of the magnetic body 210. The bottom of the support plate 2911 is fixedly connected to the top of the mounting plate 211 by a first bolt, and the magnetic body 210 can be fixed by the support plate 2911, so that the magnetic body 210 is fixed on the support plate 2911. A connecting groove is provided, and a first clamping plate 294 is fixedly connected to the inner wall of the connecting groove, and two threaded rods 296 are fixedly connected to the bottom of the first clamping plate 294, and a second clamping plate 295 is slidably connected between the outer surfaces of the threaded rods 296, and a protective pad 297 is slidably connected to the outer surface of the threaded rods 296. A nut 298 is threadedly connected to the outer surface of the threaded rods 296, and the connecting wire 299 can be fixed by the first clamping plate 294 and the second clamping plate 295 to prevent the threaded wire 2910 from moving when the connecting wire 299 is stretched. A connecting wire 299 is fixedly connected between one side of the first clamping plate 294 and the second clamping plate 295, and one end of the connecting wire 299 is electrically connected to the threaded wire 2910, and one end of the threaded wire 2910 is electrically connected to the top of the magnetic body 210. The threaded wire 2910 can prevent the magnetic body 210 from breaking due to wire entanglement when it moves.

[0045] In this embodiment, when the lifting mechanism 29 moves, the extension and retraction of the hydraulic rod 292 first drives the support plate 2911 to move, and the movement of the support plate 2911 drives the mounting plate 211 to move, thereby driving the magnetic body 210 to move up and down. When the magnetic body 210 moves, the stretchable characteristics of the threaded wire 2910 can avoid short circuit of the wiring of the magnetic body 210. During use, when the connecting wire 299 and the threaded wire 2910 need to be repaired, the nut 298 is rotated to move it downward, and then the second clamping plate 295 can be moved away from the connecting wire 299. At this time, the connecting wire 299 and the threaded wire 2910 can be repaired, and the connecting wire 299 can be fixed by the first clamping plate 294 and the second clamping plate 295, thereby preventing the connecting wire 299 from moving when the threaded wire 2910 is stretched, thereby making the structure of the connecting wire 299 more stable.

[0046] Example 3

[0047] like Figure 3 and Figure 7 As shown, the fixing mechanism 26 includes a fixing shell 261, the bottom of the fixing shell 261 is fixedly connected to the top of the fixing plate 291 by a second bolt, and the fixing shell 261 is fixedly connected to the fixing plate 291 by the second bolt, so as to facilitate the removal and installation of the fixing plate 291, and the outer surface of the fixing shell 261 is slidably connected to the convex plate 262, and the top of the fixing shell 261 is fixedly connected to a plurality of fixing rods 263, and the top of the convex plate 262 is provided with a plurality of sliding holes, and the inner wall of the sliding hole is slidably connected to the outer surface of the fixing rod 263, and the convex plate 262 can be limited by the fixing rod 263 so that the convex plate 262 can move up and down better, and the top of the convex plate 262 is fixedly connected with a plurality of springs 264, and the top of the spring 264 is fixedly connected to the top of the fixing rod 263, and the top of the fixing shell 261 is provided with a plurality of sliding holes 266, and the inner wall of the sliding hole 266 is slidably connected to a plurality of screws adapted to the rack 25 The top of the block 265 is fixedly connected to the bottom of the convex plate 262, and the outer surface of the block 265 is slidably connected to the inner wall of the rack 25. The block 265 can enter the gap of the rack 25, thereby engaging the rack 25, and then the rack 25 moves to drive the lifting mechanism 29 to move. The outer surface of the fixed shell 261 is fixedly connected to a plurality of connecting plates 267, and a card plate 2610 is rotatably connected between one side of the connecting plate 267. The outer surfaces of both sides of the two card plates 2610 are provided with a rotating groove, and the inner wall of the rotating groove is rotatably connected to a rotating rod 268. One end of the rotating rod 268 is fixedly connected to one side of the connecting plate 267, and one side of the connecting plate 267 is fixedly connected to a torsion spring 269. One end of the torsion spring 269 is fixedly connected to the inner wall of one side of the rotating groove. The torsion spring 269 can be limited by the rotating rod 268 to prevent the torsion spring 269 from bending, thereby increasing the service life of the torsion spring 269.

[0048] When the cam 262 is in contact with the top of the fixed shell 261, the card plate 2610 is pressed against the top of the cam 262, and the card plate 2610 is pressed against the top of the fixed shell 261. When the cam 262 is in contact with the top of the fixed shell 261, the card plate 2610 is pressed against the top of the cam 262 under the action of the torsion spring 269, and the installation is completed.

[0049] Working principle:

[0050] like Figure 1-7As shown, the first transmission mechanism 1 transmits the heat exchanger. After the heat exchanger is assembled, the unloading mechanism 2 removes the heat exchanger from the first transmission mechanism 1. The specific method of use is that the lifting mechanism 29 controls the magnetic body 210 to descend. After the magnetic body 210 descends to the top of the heat exchanger, the magnetic body 210 is turned on. The magnetic body 210 is an electromagnet, which is a device that can generate electromagnetics when energized. The magnetic body 210 is then fixed to the top of the heat exchanger, and then the lifting mechanism 29 controls the magnetic body 210 to move upward. The movement of the magnetic body 210 drives the heat exchanger to move, and then the stepper motor 213 is turned on. The stepper motor 213 drives the rotating plate 23 to rotate through the shaft, and the rotation of the rotating plate 23 drives one of the gears 24 to rotate, and through The rack 25 is meshed with the gear 24, so that the rotation of one gear 24 drives the other gear 24 to rotate, and the rack 25 rotates between the gears 24. At this time, the rack 25 drives the lifting mechanism 29 to move through the fixing mechanism 26, and the movement of the lifting mechanism 29 drives the magnetic body 210 to move, and the movement of the magnetic body 210 drives the heat exchanger to move. At this time, under the action of the stepping motor 213, the heat exchanger is moved to the second transmission mechanism 3. When the heat exchanger reaches the top of the packaging box 5 above the second transmission mechanism 3, the lifting mechanism 29 controls the magnetic body 210 to move downward. When the bottom of the heat exchanger contacts the bottom surface of the packaging box 5, the magnetic body 210 can be closed, and then the other mechanisms are restored to their original positions. The packaging box 5 on the second transmission mechanism 3 does not need to be turned over before packaging, thereby avoiding the packaging box 5 having strangle marks. When the lifting mechanism 29 moves, the extension and contraction of the hydraulic rod 292 first drives the support plate 2911 to move, and the movement of the support plate 2911 drives the installation plate 211 to move, thereby driving the magnetic body 210 to move up and down. When the magnetic body 210 moves, the stretchable characteristics of the threaded wire 2910 can avoid the short circuit of the wiring of the magnetic body 210. In use, when it is necessary to repair the connecting wire 299 and the threaded wire 2910, the nut 298 is turned to move it downward, and then the second clamping plate 295 can be moved away from the connecting wire 299. At this time, the connecting wire 299 and the threaded wire 2 910 is repaired, and the connecting wire 299 can be fixed by the first clamping plate 294 and the second clamping plate 295, thereby preventing the connecting wire 299 from moving when the threaded wire 2910 is stretched, thereby making the structure of the connecting wire 299 more stable, swinging the two clamping plates 2610, and the clamping plate 2610 moves and separates from the convex plate 262. At this time, the convex plate 262 moves upward under the action of the spring 264, and the movement of the convex plate 262 drives the block 265 to move, and the block 265 moves and separates from the rack 25. After that, when the rack 25 rotates on the gear 24, it will not drive the lifting mechanism 29 to move. At this time, the gear 24 and the rack 25 can be adjusted and repaired. During installation, the convex plate 262 is controlled to move downward.After the convex plate 262 contacts the top of the clamping plate 2610, the added force causes the convex plate 262 to move downward. At this time, the convex plate 262 squeezes the clamping plate 2610, causing the clamping plate 2610 to rotate outward. When the convex plate 262 contacts the top of the fixed shell 261, the clamping plate 2610 contacts the top of the convex plate 262 under the action of the torsion spring 269, and the installation is completed.
