[0031] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below in conjunction with specific implementation methods.

[0032] like Figures 1 to 8 As shown, a diaphragm compressor diaphragm 10 heat treatment equipment includes a frame 1, a lifting device 2, a support frame 3, a rotating assembly 4, a positioning assembly 5, a heating assembly 6 and a driving device 7. The bottom of the frame 1 is slidably connected to two sealed boxes 8 that can move closer to or away from each other through the driving device 7. The support frame 3 is arranged between the two sealed boxes 8 and is lifted and lowered by the lifting device 2. A plurality of support plates 31 are provided on the support frame 3, and a positioning assembly 5 is provided on the support plate 31. The positioning assembly 5 is used to support and fix the diaphragm 10; the heating assembly 6 includes a plurality of groups of induction coils 1 61 and induction coils 2 62.

[0033] The two sealing boxes 8 are close to each other to form a sealed cavity, and the induction coil 1 61 and the induction coil 2 62 are connected to form a complete induction coil, and at the same time, the disk 57 in the positioning component 5 is driven to approach the diaphragm 10 and the driving roller 43 in the rotating component 4, so that the roller clamps the diaphragm 10 while transmitting the power of the driving roller 43 to the diaphragm 10, causing the diaphragm 10 to rotate in the induction coil; a conveyor line 9 is provided on both sides of the left and right sides of the support frame 3.

[0034] In this embodiment, the heating component 6 also includes a bracket 1 63 and a bracket 2 64, the induction coil 1 61 is fixedly connected to the bracket 1 63, the bracket 1 63 is fixedly connected to the sealing box 8, and a plurality of push plates 65 are also provided on the bracket 1 63, the induction coil 2 62 is fixedly connected to the bracket 2 64, and the bracket 2 64 is fixedly connected to another sealing box 8.

[0035] In this embodiment, the positioning assembly 5 includes a trapezoidal block 50, which is slidably connected to the support plate 31.

The slide bar 1 52 is slidably connected to the stopper 311 on the support plate 31, and the slide bar 2 53 is slidably connected to the stopper 2 312 on the support plate 31. A spring 54 is sleeved on the slide bar 1 52 between the rack 1 51 and the stopper 311.

The diaphragm 10 is arranged between the four rollers 58 and is located on the disc 57.

[0036] In this embodiment, one base of the trapezoidal block 50 facing the push plate 65 is wider than the other base. This ensures that when the push plate 65 pushes the trapezoidal block 50, the oblique edge of the trapezoidal block 50 forces the two racks to move away from each other. A proximity switch 59 is also provided on the support plate 31. One of the sealed boxes 8 is equipped with an air pipe 81 that communicates with the interior. Air pipe 81 is connected to a vacuum pump and a nitrogen gas source.

[0037] In this embodiment, the rotating assembly 4 includes a fixed frame 41 and a rotating motor 42. There are two fixed frames 41, both of which are fixedly connected to the sealing box 8. A driving roller 43 is rotatably connected inside the fixed frame 41. A synchronous wheel is provided at the bottom of the driving roller 43. The two synchronous wheels are connected by a synchronous belt 44. The rotating motor 42 is fixedly connected to one of the fixed frames 41, and its output shaft is connected to the driving roller 43 on the same side.

[0038] In this embodiment, the lifting device 2 includes a base 20 and a lifting motor 21. A drive block 22 is rotatably connected to the base 20. A screw 23 is internally threadedly connected to the drive block 22. A lifting plate 24 is fixedly connected to the top of the screw 23. The support frame 3 is fixedly connected to the lifting plate 24. A support rod 25 is fixedly connected to the bottom of the lifting plate 24. The support rod 25 is slidably connected to the base 20. Gear 1 26 is fixedly connected to the outer side of the drive block 22. The lifting motor 21 is fixedly connected to the base 20, and its output shaft is fixedly connected to gear 27. Gear 1 26 meshes with gear 2 27. The top of the screw 23 has a smooth, unthreaded area. The sealing box 8 is provided with a semicircular notch for the support rod 25 and screw 23 to pass through. The semicircular notch is also sealed.

[0039] In this embodiment, the driving device 7 includes a driving motor 71, which is fixedly connected to the frame 1, and its output shaft is fixedly connected to a driving gear 72, and racks 73 are engaged on both sides of the driving gear 72. The two racks 73 are respectively fixedly connected to the two sealing boxes 8.

[0040] Working process and principle:

[0041] Initially, the two sealing boxes 8 are in a state of being away from each other, and the roller 58 on the uppermost positioning component 5 is flush with the upper surface of the conveyor line 9. The conveyor line 9 is running, and a baffle is provided on the outside of the conveyor line 9 to limit the diaphragm 10 on the conveyor line 9. When a diaphragm 10 is conveyed to the positioning component 5 through the conveyor line 9 and the uppermost proximity switch 59 detects that the diaphragm 10 reaches above the positioning component 5, the conveyor line 9 is paused.

[0042] The lifting motor 21 rotates gear 1 26 via gear 2 27, causing the driver block 22 to rotate. This rotation drives the screw upward, thereby raising the lifting plate 24 to a certain height. The diaphragm 10 then enters between the four rollers 58 and is supported by the disc 57. At this point, the angle between the two connecting rods 56 on the same side is minimal, and the four rollers 58 have not yet contacted the edges of the diaphragm 10, only serving as a preliminary limit for the diaphragm 10. The unopened positioning assembly 5 can smoothly pass through the middle of the conveyor line 9.

[0043] At the same time, the roller 58 on the second positioning component 5 also rises to be flush with the upper surface of the conveyor line 9, and the conveyor line 9 starts again, so that the second diaphragm 10 enters above the two positioning components 5. And so on, all the diaphragms 10 are placed between the four rollers 58 of the same positioning component 5, completing the initial positioning of all the diaphragms 10, and the lifting plate 24 continues to rise until the entire support frame 3 enters the area that can be sealed by the sealing box 8.

[0044] Then the driving motor 71 is started, causing the driving gear 72 to rotate, prompting the two racks 73 to drive the two sealing boxes 8 to move closer to each other. The contact surfaces of the two sealing boxes 8 are provided with sealing gaskets to assist in sealing.

[0045] In the process of the two sealing boxes 8 approaching each other, the push plate 65 acts on the trapezoidal block 50, causing the trapezoidal block 50 to move. The inclined surface of the trapezoidal block 50 presses against the slide bar 2 53, causing the two slide bars 2 53 to move away from each other. The spring 54 is compressed, and the two racks 1 51 move from the center to both sides. The clamping gear 55 rotates, and the angle between the two connecting rods 56 increases. The roller 58 moves toward the edge of the driving roller 43 and the diaphragm 10, and finally contacts the disc 57 and the driving roller 43, and the roller 58 contacts the diaphragm 10. When the roller 58 contacts the diaphragm 10, the diaphragm 10 can be clamped between the four rollers 58 to achieve fixation.

[0046] When the two sealed boxes 8 approach each other, the induction coil 1 61 and the induction coil 2 62 also approach each other, and finally the diaphragm 10 is put into the complete induction coil after the induction coil 1 61 and the induction coil 2 62 are connected.

[0047] The air in the closed cavity of the two sealed boxes 8 is then evacuated to prevent the oxygen remaining in the air from oxidizing the diaphragm 10 when the diaphragm 10 is heated.

[0048] After the air is exhausted, the rotating motor 42 is started, and all the driving rollers 43 rotate synchronously, driving all the discs 57 to rotate. The discs 57 and the rollers 58 contact the diaphragm 10, causing the diaphragm 10 to rotate.

[0049] Current flows from induction coil 1 61 to induction coil 2 62 and then out of induction coil 1 61, forming a closed loop. The complete induction coil now induction heats the diaphragm 10. Because the induction coil covers the entire diameter of the diaphragm 10, all diaphragms 10 and every location on the diaphragm 10 can be heated simultaneously as the diaphragm 10 rotates. This avoids the disadvantage of not being able to simultaneously heat deeper diaphragms 10 and areas when stacking diaphragms 10, and facilitates uniform heat treatment time and intensity for each diaphragm 10.

[0050] After the heat treatment of the diaphragm 10 is completed, nitrogen is introduced from the air source to cool the diaphragm 10. After cooling, the sealing boxes 8 move away from each other, the trapezoidal block 50 and the rack 51 are reset under the action of the spring 54, the angle of the connecting rod 56 becomes smaller, the roller 58 moves away from the edge of the diaphragm 10 and the driving roller 43, and the diaphragm 10 is loosened and stops rotating.

[0051] After that, the support frame 3 is lowered to a certain height each time, so that the diaphragm 10 returns to the conveyor line 9, and the conveyor line 9 is started in the reverse direction, driving the diaphragm 10 to separate from the positioning component 5, thereby realizing automatic unloading of the diaphragm 10.

[0052] It is understood from common technical knowledge that the present invention may be implemented by other embodiments that do not depart from its spirit or essential features. Therefore, the embodiments disclosed above are, in all respects, merely illustrative and not exclusive. All modifications within the scope of the present invention or equivalent to the scope of the present invention are intended to be encompassed by the present invention.
