DETAILED DESCRIPTION

[0023] The technical scheme in the embodiments of the utility model will be clearly and completely described in combination with the drawings in the embodiments of the utility model, obviously, the described embodiments only some embodiments of the utility model, not all embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary skilled person in the art without making creative labor belong to the scope of protection of the utility model.

[0024] The following gives specific embodiments.

[0025] AsFigures 1 to 5 As shown in the figure, a gas meter diaphragm uniform preheating device according to an embodiment of the present invention includes an operating table 1; a linear motor 11 is fixedly connected to the operating table 1; a support base 12 is fixedly connected to the output end of the linear motor 11; a connecting plate 13 is fixedly connected to the support base 12; multiple suction pipes 14 are connected to the connecting plate 13; a pair of connecting pipes 15 are connected to the connecting plate 13; the connecting pipes 15 are elastic structures; and a suction pump 16 is connected to the end of the connecting pipes 15; the operating table 1... A support frame 17 is fixedly connected to the upper part; multiple air supply pipes 18 are installed through the support frame 17; a connecting block 19 is fixedly connected to the end of the air supply pipe 18; multiple air outlet holes 110 are opened on the connecting block 19; the diaphragm body is placed on the air extraction pipe 14 and then the air extraction pump 16 is turned on. After the air extraction pump 16 is turned on, the air in the connecting pipe 15 is extracted, and a suction force is formed at the air extraction pipe 14 to adsorb and fix the diaphragm body. When the diaphragm body is fixed, the linear motor 11 is turned on, and the linear motor 11 moves forward. The diaphragm body is inserted into the support frame 17. When the linear motor 11 moves, it stretches the connecting pipe 15. At this time, hot air is injected into the air supply pipe 18. When the hot air is ejected from the multiple air outlets 110 on the connecting block 19 through the air supply pipe 18, it is blown between multiple suction pipes 14. When the hot air contacts the diaphragm surface, it preheats the diaphragm body. Because multiple suction pipes 14 are connected to the connecting plate 13, a negative pressure zone is formed at the suction pipes 14 when air is drawn into them. The diaphragm body is fixed in place, and the air extraction pipe 14 suspends the diaphragm body, which allows the diaphragm body to be heated more evenly on both sides during the preheating process. At the same time, the hot air in the air supply pipe 18 is ejected from the multiple air outlets 110 on the connecting block 19 and dispersed by the air outlets 110. The dispersed hot air can also make better contact with the diaphragm body, making the diaphragm body heat more evenly and reducing the uneven heating of the diaphragm body during the preheating process caused by placing the diaphragm body directly on the fixed platform.

[0026] like Figure 2 As shown, the suction pipe 14 is connected to a diffuser 2; the diffuser 2 has a funnel-shaped structure. When the diaphragm body is placed on the suction pipe 14, the diaphragm body and the diffuser 2 come into contact. At this time, the contact area between the suction pipe 14 and the diaphragm body increases. By connecting the diffuser 2 to the end of the suction pipe 14, the contact area between the suction pipe 14 and the diaphragm body can be increased when the suction pipe 14 adsorbs and fixes the diaphragm body, reducing the situation where the diaphragm body is deformed due to excessive suction at the suction pipe 14. At the same time, by adding the diffuser 2, the situation where the diaphragm body directly contacts the suction pipe 14 and the suction pipe 14 causes scratches to the diaphragm body can be reduced.

[0027] like Figure 3As shown, the diffusion port 2 is fixed with a mesh plate 3; the mesh plate 3 is provided with a plurality of mesh holes 31, when the diaphragm body is placed on the diffusion port 2, the diffusion port 2 fixes the diaphragm body, when the diaphragm body has residual debris generated during production, the mesh plate 3 blocks the debris, by fixing the mesh plate 3 on the diffusion port 2, and providing a plurality of mesh holes 31 on the mesh plate 3, the residual debris on the diaphragm body can be blocked when the diaphragm body is fixed, reducing the situation that the debris enters the suction pipe 14 and causes the suction pipe 14 to be blocked.

[0028] As shown in the Figure 4 As shown, the connecting plate 13 is fixed with a support column 4; the end of the support column 4 is fixed with a ball 41, when the diaphragm body is placed on the diffusion port 2, the ball 41 lifts the diaphragm body to make the diaphragm body fully stretched, by fixing the support column 4 on the connecting plate 13, and rotating the ball 41 on the support column 4, the diaphragm body can be lifted to maintain the tension of the diaphragm body when the diaphragm body is fixed, reducing the situation that the diaphragm body is unevenly heated due to wrinkles during preheating.

[0029] As shown in the Figure 5 As shown, the connecting block 19 is fixed with a connecting column 5; the end of the connecting column 5 is rotatably connected with a plurality of fan leaves 51, when the hot air enters the gas conveying pipe 18 and is sprayed out of the air outlet hole 110, the hot air pushes the fan leaves 51 to rotate, the rotating fan leaves 51 diffuse the hot air and send it between the plurality of suction pipes 14, when the hot air enters between the plurality of suction pipes 14, the hot air fully contacts the diaphragm body, by rotatably connecting the plurality of fan leaves 51 at the end of the connecting column 5, the hot air sprayed out of the air outlet hole 110 can be diffused when the diaphragm body is preheated, increasing the contact area between the hot air and the diaphragm body, and enhancing the preheating effect of the diaphragm body.

[0030] As shown in the Figure 5 As shown, the inner side wall of the support frame 17 is provided with a plurality of heat preservation curtains 6; the heat preservation curtains 6 are located between the operation table 1 and the support frame 17, when the diaphragm body is sent into the support frame 17 for preheating, the heat preservation curtains 6 block the hot air in the support frame 17, by fixing a plurality of heat preservation curtains 6 on the inner side wall of the support frame 17, the hot air can be blocked in the support frame 17 as much as possible when the diaphragm body is preheated, the temperature in the support frame 17 is maintained, and the heat loss is reduced.

[0031] Working principle: the diaphragm body is placed on the suction pipe 14, and then the suction pump 16 is started. When the suction pump 16 is started, the air in the connecting pipe 15 is sucked out to form suction on the diaphragm body at the suction pipe 14. When the diaphragm body is fixed, the linear motor 11 is started. When the linear motor 11 moves forward, the diaphragm body is sent into the support frame 17. At this time, hot air is injected into the gas supply pipe 18. When the hot air is injected from the multiple air outlet holes 110 on the connecting block 19 through the gas supply pipe 18, the hot air is sent to the multiple suction pipes 14. When the hot air contacts the surface of the diaphragm, the diaphragm body is preheated. When the diaphragm body is placed on the suction pipe 14, the diaphragm body contacts the diffusion port 2. At this time, the contact area between the suction pipe 14 and the diaphragm body increases. When the diaphragm body is placed on the diffusion port 2, the diffusion port 2 fixes the diaphragm body. When the diaphragm body has residual debris produced during production, the mesh plate 3 blocks the debris. When the diaphragm body is placed on the diffusion port 2, the ball 41 lifts the diaphragm body to make the diaphragm body fully stretch. When the hot air enters the gas supply pipe 18 and is injected from the air outlet hole 110, the hot air drives the fan blade 51 to rotate. The rotating fan blade 51 diffuses the hot air and sends it to the multiple suction pipes 14. When the hot air enters the multiple suction pipes 14, the hot air fully contacts the diaphragm body. When the diaphragm body is sent into the support frame 17 for preheating, the heat preservation curtain 6 blocks the hot air in the support frame 17. By fixing multiple heat preservation curtains 6 on the inner wall of the support frame 17, the hot air can be blocked in the support frame 17 as much as possible when the diaphragm body is preheated, the temperature in the support frame 17 is maintained, and the heat loss is reduced.

Those skilled in the art should understand that the present application is not limited to the above embodiments, and the above embodiments and descriptions in the specification are only to illustrate the principles of the present application. Without departing from the spirit and scope of the present application, various changes and improvements can be made to the present application, and these changes and improvements all fall within the scope of the claimed present application.
