Description

Technical Field

[0001] This utility model relates to the field of diaphragm production, and in particular to an oil suction device and a membrane stretching equipment. Background Technology

[0002] In existing membrane manufacturing processes, organic solvents such as dichloromethane are often used to remove white oil adhering to the membrane. White oil is a commonly used pore-forming agent in membrane production; incomplete removal not only affects membrane quality but may also cause unnecessary interference in subsequent processing. Currently, extraction with dichloromethane solution can effectively remove this white oil, thereby ensuring membrane quality.

[0003] However, the number and scale of extraction tanks directly affect the process speed of diaphragm production. In existing technologies, increasing the production speed typically requires increasing the number of extraction tanks, which undoubtedly leads to a significant increase in equipment investment and operating costs. Especially when production demand is high or production scale is expanded, increasing the number of extraction tanks not only requires substantial capital investment but also increases costs related to equipment maintenance, management, and energy consumption. Therefore, there is an urgent need for a low-investment solution to improve diaphragm production efficiency. Utility Model Content

[0004] In order to overcome the shortcomings of the prior art, this utility model provides an oil suction device and a membrane stretching device that can efficiently remove grease from the surface of a diaphragm.

[0005] The technical solution adopted by this utility model to solve its technical problem is:

[0006] An oil-absorbing device for removing grease adhering to the surface of a diaphragm, comprising:

[0007] A mounting frame and a first roller and a second roller mounted on the mounting frame via bearing seats. The first side of the diaphragm contacts the first roller, and the second side of the diaphragm contacts the second roller. Oil suction mechanisms are respectively provided at both ends of one side of the first roller and the second roller. These oil suction mechanisms are used to remove grease from the edges of the diaphragm passing through the first roller and the second roller. A mounting beam is fixedly mounted on the mounting frame. The oil suction mechanism includes: an oil suction roller mounted on the mounting beam and corresponding to the position on the diaphragm where oil removal is required; and an adsorption device connected to the oil suction roller, used to provide negative pressure during startup, allowing the oil suction roller to absorb grease from the diaphragm.

[0008] Furthermore, the oil suction mechanism also includes a cylinder disposed on the mounting beam, and the oil suction roller is mounted on the output end of the cylinder;

[0009] The cylinder pushes the oil suction roller toward the diaphragm, pressing the diaphragm onto the roller to suck up oil.

[0010] Furthermore, the mounting beam is provided with a guide rail, and the cylinder is connected to a slide block that cooperates with the guide rail, allowing the cylinder to slide on the guide rail via the slide block.

[0011] Furthermore, a fixing member is provided on the slide block. One end of the fixing member is threadedly connected to the slide block, and the other end abuts against the mounting beam. After adjusting the position of the slide block on the guide rail, the oil suction position of the oil suction roller can be fixed by rotating the fixing member.

[0012] Furthermore, a handle is provided at the end of the fastener away from the mounting beam.

[0013] Furthermore, limit blocks are provided at both ends of the guide rail.

[0014] Furthermore, the mounting frame is provided with a first driving member that is drivenly connected to the first roller body, and a second driving member that is drivenly connected to the second roller body.

[0015] Furthermore, both the first driving component and the second driving component are motors connected to a speed reducer.

[0016] Furthermore, the adsorption device comprises a vacuum pump, an oil suction pipe, and a control valve. The vacuum pump is connected to the oil suction roller through the oil suction pipe, and the negative pressure is adjusted by the control valve.

[0017] A membrane stretching device further includes an oil suction device arranged sequentially along the conveying path of the membrane, and an extraction device, wherein the extraction device is used to remove the remaining oil on the membrane after being treated by the oil suction device.

[0018] The beneficial effects of this utility model are:

[0019] This invention relates to an oil suction device and a membrane stretching apparatus. The first and second rollers of the oil suction device contact both sides of the diaphragm, effectively guiding the diaphragm as it passes through the suction rollers. Through negative pressure adsorption, most of the grease on the diaphragm is adsorbed and removed. Subsequently, the membrane stretching apparatus uses an extraction device to completely remove any remaining grease. Because the oil suction device significantly reduces the grease content on the diaphragm surface, the workload of the extraction equipment is greatly reduced, thereby improving solvent utilization efficiency, shortening extraction time, and reducing solvent consumption. This increases diaphragm production efficiency without increasing the number of extraction tanks. Attached Figure Description

[0031] The following will clearly and completely describe the concept, specific structure, and technical effects of this utility model in conjunction with embodiments and accompanying drawings, so as to fully understand the purpose, features, and effects of this utility model. Obviously, the described embodiments are only a part of the embodiments of this utility model, not all of them. Other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are all within the scope of protection of this utility model. Furthermore, all connections / linkages involved in the patent do not simply refer to direct contact between components, but rather to the ability to form a better connection structure by adding or reducing connecting accessories according to specific implementation conditions. The various technical features in this utility model can be combined interactively without contradicting each other.

[0032] Reference Figure 1 In the membrane stretching production line, the extraction device 400 of the membrane stretching equipment removes the remaining oil on the surface of the diaphragm 100. Since most of the oil is concentrated on the edges of both sides of the diaphragm 100 before entering the extraction device 400, the oil suction device of this invention removes the oil from the edges of both sides of the diaphragm 100, thereby effectively reducing the residual oil content on the diaphragm 100 before entering the extraction tank, and improving the extraction efficiency and quality of the extraction device 400.

[0033] Reference Figure 1-4An oil-absorbing device for removing grease from the surface of a diaphragm 100 includes: a mounting frame 200 and a first roller 220 and a second roller 230 mounted on the mounting frame 200 via a bearing seat 210. A first side of the diaphragm 100 contacts the first roller 220, and a second side of the diaphragm 100 contacts the second roller 230. Oil-absorbing mechanisms 300 are respectively provided at both ends of one side of the first roller 220 and the second roller 230. The oil-absorbing mechanisms 300 are used to remove grease from the edges of the diaphragm 100 passing through the first roller 220 and the second roller 230. It is understood that the diaphragm 100 changes its transmission direction via the first roller 220 and the second roller 230. By providing oil-absorbing mechanisms 300 along the transmission path, grease can be removed from the edges of both sides of the diaphragm 100. The grease referred to here is white oil. A mounting beam 240 is fixedly mounted on the mounting frame 200. The oil suction mechanism 300 includes: an oil suction roller 310, mounted on the mounting beam 240 and corresponding to the position on the diaphragm 100 where oil needs to be suctioned; and an adsorption device 320, connected to the oil suction roller 310, used to provide negative pressure during startup, allowing the oil suction roller 310 to absorb grease from the diaphragm 100. It is understood that the surface of the oil suction roller 310 can be made of a material with a certain degree of flexibility and adsorption, such as felt, to enhance the adsorption capacity for grease and provide good friction to ensure the smooth passage of the diaphragm 100. The adsorption device 320 includes a vacuum pump, an oil suction pipe, and a control valve, which can adjust the negative pressure as needed to ensure effective adsorption when the oil suction roller 310 contacts the diaphragm 100. Of course, the adsorption device 320 can be any device that provides adsorption function besides a vacuum pump; this is not limited here.

[0034] The oil suction device removes most of the grease from the edges of the diaphragm 100. The diaphragm 100 then enters the extraction device 400, where an extraction tank containing an extraction solution removes the grease from its surface. It is understood that by the time the diaphragm 100 enters the extraction device 400, most of the grease on its surface has already been removed by the oil suction device. Therefore, without adding an extraction tank, the production speed of the diaphragm 100 can be increased, significantly reducing production costs. It should be noted that the grease on the diaphragm 100 in this case is white oil, and the extraction solution in the extraction tank is dichloromethane liquid.

[0035] In some embodiments, refer to Figure 2-4The oil suction mechanism 300 further includes a cylinder 330 mounted on the mounting beam 240, and an oil suction roller 310 mounted on the output end of the cylinder 330. The cylinder 330 pushes the oil suction roller 310 towards the diaphragm 100, pressing the diaphragm 100 onto the roller body for oil suction. The function of the cylinder 330 is to control the contact pressure between the oil suction roller 310 and the diaphragm 100, thereby effectively removing grease from the edges of the diaphragm 100. The cylinder 330 can adjust the pressure and stroke as needed to ensure appropriate contact between the oil suction roller 310 and the diaphragm 100 during the suction process, thus avoiding excessive pressure or damage to the diaphragm 100. Simultaneously, the control system of the cylinder 330 can be linked with other equipment in the automated production line to achieve precise operation and an efficient oil suction process.

[0036] Furthermore, refer to Figure 4 The mounting beam 240 is equipped with a guide rail 241, and the cylinder 330 is connected to a slide block 340 that cooperates with the guide rail 241. The cylinder 330 can slide on the guide rail 241 via the slide block 340. It should be noted that the cylinder 330 is mainly used to control the contact distance between the oil suction roller 310 and the diaphragm 100, thereby adjusting the pressure of the oil suction roller 310 on the diaphragm 100 to ensure effective grease removal. The guide rail 241 is used to control the movement of the oil suction roller 310 in the width direction of the diaphragm 100, allowing the oil suction roller 310 to precisely adjust its relative position according to different widths of the diaphragm 100, thereby achieving all-round oil suction of the edge area of ​​the diaphragm 100. Through the cooperation of the guide rail 241 and the slide block 340, the oil suction roller 310 can slide smoothly in the width direction of the diaphragm 100, ensuring that the oil suction roller 310 maintains good contact with the edge of the diaphragm 100 regardless of changes in the size of the diaphragm 100 during production.

[0037] Furthermore, the guide rail 241 can be a single section or two sections. That is, the oil suction mechanisms 300 located at both ends of the diaphragm 100 can be installed on the same guide rail 241 or on different guide rails 241. Since the general operating condition of this utility model is to remove grease located on both sides of the diaphragm 100 through the oil suction mechanism 300, it is preferable to provide two shorter guide rails 241 at each end of the mounting beam 240.

[0038] Furthermore, refer to Figure 4A fixing member 350 is provided on the slide block 340. One end of the fixing member 350 is threadedly connected to the slide block 340, and the other end abuts against the mounting beam 240. After adjusting the position of the slide block 340 on the guide rail 241, the oil suction position of the oil suction roller 310 can be fixed by rotating the fixing member 350. It is understood that when adjusting the position of the slide block 340, the operator fixes the oil suction position of the oil suction roller 310 by rotating the fixing member 350. The operator can quickly adjust the position of the oil suction roller 310 under different production needs and ensure its stability by rotating the fixing member 350, preventing positional shift or loosening during operation. The threaded connection of the fixing member 350 is simple and easy to implement, providing a reliable positioning effect and ensuring accurate and stable contact between the oil suction roller 310 and the diaphragm 100.

[0039] Further, continue to refer to Figure 4 The handle 351 enhances the operator's rotational force on the fixing component 350, ensuring a more secure fixation of the oil suction roller 310 after adjustment. This prevents loosening or displacement during use, thus guaranteeing stable equipment operation. In other words, the operator can perform precise adjustments and fixations without tools, further improving the ease of operation of the equipment and the automation level of the production line.

[0040] Furthermore, limit blocks 242 are provided at both ends of the guide rail 241. The limit blocks 242 can prevent the slide 340 from sliding excessively on the guide rail 241, ensuring that the oil suction roller 310 always remains within the predetermined range of movement during operation. It can be understood that the limit blocks 242, through physical blocking, can limit the movement distance of the slide 340, avoiding equipment damage or positional displacement caused by excessive sliding, thereby ensuring the stability and accuracy of the production process.

[0041] In some embodiments, refer to Figure 1 The mounting frame 200 is equipped with a first drive member 250 that is driveably connected to the first roller body 220, and a second drive member 260 that is driveably connected to the second roller body 230. It is understood that the first drive member 250 and the second drive member 260 can achieve independent or synchronous control of the first roller body 220 and the second roller body 230, thereby realizing the adjustment and drive of the oil suction roller 310. Specifically, the first drive member 250 and the second drive member 260 can be a motor, a servo motor, or a pneumatic drive device, used to drive the rotation of the roller body, ensuring that it can generate the required power to drive the diaphragm 100 or other materials during operation. Preferably, the first drive member 250 and the second drive member 260 are motors.

[0042] Furthermore, both the first drive component 250 and the second drive component 260 are motors connected to a speed reducer. It is understood that the cooperation between the speed reducer and the motor enables the first roller 220 and the second roller 230 to operate at a lower speed and higher torque, thereby providing sufficient power to drive the diaphragm 100 for transmission, while reducing vibration and wear during the movement of the rollers.

[0043] The above is a detailed description of the preferred embodiments of the present utility model. However, the present utility model is not limited to the described embodiments. Those skilled in the art can make various equivalent modifications or substitutions without departing from the spirit of the present utility model. All such equivalent modifications or substitutions are included within the scope defined by the claims of this application.
