[0041] Please refer to Figures 1 to 4 The present application provides a kind of membrane flat equipment, comprising:

[0042] Bottom plate 1, top plate 2 is horizontally provided by support above bottom plate 1;

[0043] Heating plate 3 is horizontally arranged on bottom plate 1, and a plurality of pressing plates 4 are further arranged above heating plate 3, and the pressing plate 4 is movably installed on top plate 2;

[0044] Driving device 5, driving device 5 is used to drive each pressing plate 4 to be close to or away from heating plate 3;

[0045] Roller 6, both ends of roller 6 are horizontally arranged between bottom plate 1 and top plate 2 by sliding groove assembly, and roller 6 is used to roll on the upper surface of heating plate 3.

[0046] In one embodiment, in order to achieve the effect of uniform heating, heating plate 3 is a metal plate, copper plate can be used to ensure rapid heat transfer and uniform distribution, and electric heating alloy wire in a serpentine or mesh layout is further arranged in heating plate 3, so that the electric heating alloy wire is uniformly distributed on heating plate 3.

[0047] Among them, the support is a plurality of columns, which are vertically arranged between the bottom plate 1 and the top plate 2, and the columns are located at the edge of the bottom plate 1, wherein the columns are connected between the bottom plate 1 and the top plate 2 in a detachable manner, such as threaded connection, which can provide stable support and enable the bottom plate 1 or the top plate 2 to be replaced.

[0048] In one of the embodiments, in order to adjust the distance between the bottom plate 1 and the top plate 2, the column can be a telescopic structure, which includes an upper connecting rod and a lower connecting rod, the upper connecting rod and the lower connecting rod are connected through a connecting cylinder, the connecting cylinder is threadedly connected with the upper connecting rod and the lower connecting rod, the threads on the outer walls of the upper connecting rod and the lower connecting rod are opposite, and a limiting structure is arranged at both ends of the connecting cylinder and used for axially limiting the upper connecting rod and the lower connecting rod.

[0049] In use, the film can be placed on the heating plate 3, and the roller 6 is used to roll on the film to smooth the wrinkles, while the roller 6 is working, the corresponding pressing plate 4 is driven by the driving device 5 to press the film at the smoothed part, so as to ensure the smoothing effect and avoid the rebound of the wrinkles due to untimely operation, so that the film can be as flat as possible before being clamped for smoothing, thereby reducing the influence on the subsequent process and the performance of the film.

[0050] For example, the sliding groove assembly includes a lower sliding rail 8, which is installed on the bottom plate 1, and the end of the roller 6 is provided with a roller, which is arranged to roll on the lower sliding rail 8, and the purpose of arranging the lower sliding rail 8 is to provide rolling guidance and support for the roller 6.

[0051] It should be further pointed out that, in order to adjust the height of the lower sliding rail 8, the lower sliding rail 8 can be arranged on the bottom plate 1 through a lifting mechanism, which can be a pneumatic cylinder, and the lower sliding rail 8 is close to the corresponding column, which can be guided by the column to lift the lower sliding rail 8, so that the distance between the rolling surface of the roller 6 and the heating plate 3 can be adjusted, and the present application can adapt to films of various thicknesses.

[0052] For example, the sliding groove assembly further includes an upper sliding rail 7, which is arranged on the support between the bottom plate 1 and the top plate 2, and the upper sliding rail 7 is horizontally located above the lower sliding rail 8, and the roller is arranged to roll between the upper sliding rail 7 and the corresponding lower sliding rail 8.

[0053] In one of the embodiments, in order to vertically limit the roller 6, the connection relationship between the upper sliding rail 7 and the support is detachable, so that the upper sliding rail 7 can be arranged at different heights of the support, so that the distance between the upper sliding rail 7 and the lower sliding rail 8 can be adjusted, and rollers of various sizes can be arranged to apply different pressures.

[0054] It should be further pointed out that, in order to replace and maintain the upper sliding rail 7, the upper sliding rail 7 can be detachably installed on the corresponding support through bolts, and the upper sliding rail 7 can also be installed by a lifting motor, which further enhances the convenience of height adjustment of the upper sliding rail 7.

[0055] It should be noted that the purpose of setting the upper slide rail 7 is to limit the drum 6, so as to avoid the drum 6 from jumping due to wrinkles, causing insufficient pressure and being unable to effectively smooth the wrinkles, so that the drum 6 can stably run along the length direction of the slide rail 7 when rolling. At the same time, the drum 6 is limited by the upper slide rail 7, so as to avoid the situation that the drum 6 cannot be flattened due to insufficient pressure when encountering wrinkles. Meanwhile, the limiting effect of the upper slide rail 7 makes the pressure applied by the drum 6 to the membrane uniform during the rolling process.

[0056] For example, the membrane flattening device further comprises at least one power device 9, which is used to drive the drum 6 to move along the length direction of the upper slide rail 7 and the lower slide rail 8.

[0057] In one embodiment, the power device 9 can be a telescopic motor, which is fixedly connected between the base plate 1. Rotating shafts are further arranged at both ends of the drum 6. The telescopic motor is connected to the rotating shafts at both ends of the drum 6 through a bearing. The inner ring of the bearing is sleeved on the rotating shaft, and the outer ring of the bearing is fixedly connected to the end of the telescopic rod.

[0058] For example, the rollers are gears, the upper slide rail 7 and the lower slide rail 8 are provided with racks along the length direction thereof, and grooves are arranged on the upper slide rail 7 or the lower slide rail 8. The power device 9 can slide horizontally along the grooves, and the power device 9 is used to drive the rollers to move along the corresponding racks. The connection mode of the gear and the rack avoids the drum 6 from idling at the original position.

[0059] In one embodiment, the power device 9 can also be a rotary motor. When driving the drum 6 to rotate, the power device 9 is limited by the corresponding grooves, so that the power device 9 will not rotate, and the rotation of the drum 6 will force the drum 6 to move between the upper slide rail 7 and the lower slide rail 8.

[0060] In the protective shell arranged on the outer wall of the power device 9, the power device 9 is protected and installed. The delivery end of the power device 9 extends out of the protective shell. Two insertion blocks are arranged on the protective shell. The insertion blocks are used to insert into the corresponding grooves to limit the power device 9 from rotating by itself during the process of driving the drum 6 to rotate, and at the same time, the power device 9 can slide along the length direction of the grooves.

[0061] For example, the outer wall of the drum 6 is further provided with a buffer layer.

[0062] It should be noted that the buffer layer can be made of silica gel or other buffer materials. Silica gel has excellent softness, elasticity and high temperature resistance, and good chemical stability, and is not easy to react with the proton membrane or the catalyst layer. In addition, silica gel material is easy to clean and replace, and is very suitable for flattening the wrinkles of the proton membrane and the catalyst layer, and protecting the membrane.

[0063] In one embodiment, the buffer layer is made of elastic material, which is high-temperature resistant rubber, so that the roller 6 can avoid damaging the film during rolling.

[0064] For example, the driving device 5 includes a plurality of driving units, each of which is used to drive a corresponding pressing plate 4 to move close to or away from the heating plate 3.

[0065] It should be noted that the driving unit is a pneumatic cylinder. When the roller 6 flattens the film, the corresponding driving unit timely uses the pressing plate 4 to press the film to avoid the rebound of the wrinkles and affect the flattening effect, so as to realize the independent driving of each pressing plate 4.

[0066] When each driving unit drives the pressing plate 4, a plurality of sensors can be arranged on the top plate 2, each sensor corresponding to a driving unit. After the sensor senses the passing of the roller 6, the corresponding driving unit drives the corresponding pressing plate 4 to press the heating plate 3.

[0067] Further, after the roller 6 is started, the first driving unit is started after n seconds, the second driving unit is started after n seconds from the start of the first driving unit, and so on, to ensure that the pressing plate 4 can timely press the film after the roller 6 passes and flattens.

[0068] In one embodiment, the sensor on the top plate 2 is a thermocouple sensor or a thermal resistance sensor, which is used to sense the movement of the pressing plate 4 or the corresponding driving unit.

[0069] For example, to avoid the film from shifting on the heating plate 3, the heating plate 3 is also provided with a plurality of suction holes a, all of which are uniformly distributed on the heating plate 3. A suction device is arranged in the bottom plate 1, which is used to provide negative pressure to all the suction holes a.

[0070] It should be noted that the suction device is a negative pressure pipeline, which is arranged in the bottom plate 1 and connected with all the suction holes a. The negative pressure pipeline is used to connect a negative pressure machine. In use, the negative pressure machine works to generate negative pressure, which is transmitted to each suction hole a through the negative pressure pipeline. The suction hole a adsorbs the film on the heating plate 3.

[0071] For example, the bottom plate 1 is also provided with a suction switch 10 and a temperature switch 11.

[0072] It should be noted that the suction switch 10 is used to control the working state of the suction hole a. At the same time, the suction switch 10 can be designed as a knob switch. By rotating the angle of the suction switch 10, the suction capacity of the suction hole a can be adjusted.

[0073] Further, the working state of the heating plate 3 is controlled by the temperature switch 11, wherein the temperature switch 11 can also be a rotary switch, and the heating temperature of the heating plate 3 is adjusted by rotating the temperature switch 11.

[0074] In summary, the membrane flatness equipment of the utility model utilizes the cylinder 6 to smooth the wrinkles on the membrane, and utilizes the driving device 5 to drive the corresponding pressing plate 4 in batches to press the flattened part of the membrane in time, so as to ensure the flattening effect, avoid the problem of wrinkle rebound caused by untimely operation, effectively reduce the generation of wrinkles, improve the flatness and quality of the membrane, and thus ensure the sealing performance and electrolysis efficiency of the electrolytic cell.

[0075] The above embodiment only exemplarily illustrates the principle and effect of the utility model, and is not used to limit the utility model. Any person skilled in the art can modify or change the above embodiment without departing from the spirit and category of the utility model. Therefore, all equivalent modifications or changes completed by those skilled in the art without departing from the spirit and technical thought of the utility model should be covered by the claims of the utility model.
