Description

Technical Field

[0001] This utility model relates to the field of winding device technology, specifically a high-speed winding device for reverse osmosis membrane nonwoven fabric with a flexible buffer structure. Background Technology

[0002] Currently, non-woven fabric is the main material used as the support layer for reverse osmosis membranes. However, non-woven fabric support materials prepared with different materials and processes have significant performance differences. How to optimize the production conditions and product quality of reverse osmosis membranes by improving the preparation process of non-woven fabric support materials has become a current research focus.

[0003] When winding up the nonwoven fabric of the reverse osmosis membrane, a winding device is required. However, the winding device does not have a buffer structure, which can cause the nonwoven fabric of the reverse osmosis membrane to wrinkle, be stretched, or even break during the winding process. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a high-speed winding device for reverse osmosis membrane nonwoven fabric with a flexible buffer structure. It has the advantages of providing winding and buffering for reverse osmosis membrane nonwoven fabric, thus solving the problem that the winding device does not have a buffering function when winding reverse osmosis membrane nonwoven fabric.

[0005] This utility model discloses a high-speed winding device for nonwoven reverse osmosis membrane fabric with a flexible buffer structure. It includes a worktable, a winding assembly on the left side of the top of the worktable, two material guiding assemblies on the right side of the top of the worktable, and a buffer assembly on one side of each of the two material guiding assemblies. Each buffer assembly includes a frame, the bottom of which is fixedly connected to the worktable. Slide rods are provided on both sides of the inner cavity of the frame. Slide sleeves are movably fitted onto the surface of each slide rod. A shock-absorbing spring is provided at the connection between the top of the slide sleeve and the frame, and the shock-absorbing spring is fitted onto the surface of the slide rod. A threaded sleeve is fitted onto the bottom of the slide rod surface, and a threaded groove adapted to the threaded sleeve is formed at the bottom of the slide rod surface. The two corresponding sides of the slide sleeves can rotate. With the buffer roller connected, this invention provides a buffering function for the reverse osmosis membrane nonwoven fabric. First, the screw sleeve is rotated, and the sliding sleeve is limited by the threaded groove on the sliding rod. The upward movement of the sliding sleeve limits the damping force of the shock-absorbing spring. When the reverse osmosis membrane nonwoven fabric is transmitted through the buffer roller, the impact force is transmitted to the sliding sleeve. At this time, the sliding sleeve moves on the sliding rod, and the impact force is transmitted to the shock-absorbing spring through the sliding sleeve. The shock-absorbing spring can reduce the impact force to a minimum. This makes the reverse osmosis membrane nonwoven fabric more effective when winding, avoiding the situation where the winding device does not have a buffer structure, which would cause the reverse osmosis membrane nonwoven fabric to wrinkle, tensile damage, or even breakage during the winding process.

[0006] This invention relates to a high-speed winding device for reverse osmosis membrane nonwoven fabric with a flexible buffer structure. The winding assembly includes a concave plate, the bottom of which is fixedly connected to a worktable. A first mounting plate is movably connected to one end of the inner cavity of the concave plate, and a motor is provided at the other end of the concave plate. The output end of the motor passes through and extends into the inner cavity of the concave plate, where a second mounting plate is provided. When it is necessary to wind up the reverse osmosis membrane nonwoven fabric, the winding roller is first installed on the first and second mounting plates. At this time, the motor runs, driving the second mounting plate to rotate. The second and first mounting plates cooperate with the winding roller to rotate, thereby winding up the reverse osmosis membrane nonwoven fabric.

[0007] This invention relates to a high-speed winding device for reverse osmosis membrane nonwoven fabric with a flexible buffer structure. The guiding component includes two connecting plates, the bottoms of which are fixedly connected to the worktable. A guiding roller is rotatably connected to one side of each connecting plate. The guiding roller can limit the movement of the reverse osmosis membrane nonwoven fabric during winding, thus preventing the reverse osmosis membrane nonwoven fabric from shifting during winding and thus avoiding poor winding effect.

[0008] The present invention relates to a high-speed winding device for reverse osmosis membrane nonwoven fabric with a flexible buffer structure, wherein the surface of the screw sleeve is provided with anti-slip threads, and the screw sleeve is located below the sliding sleeve.

[0009] This utility model discloses a high-speed winding device for reverse osmosis membrane nonwoven fabric with a flexible buffer structure, wherein a movable rod is fixedly connected to the outer side of the sliding sleeve, and sliding grooves adapted to the movable rod are provided on both sides of the inner cavity of the frame.

[0010] This utility model discloses a high-speed winding device for nonwoven fabric of reverse osmosis membrane with a flexible buffer structure. The bottom of the worktable is provided with an anti-slip pad, and the bottom of the anti-slip pad is provided with anti-slip particles. The anti-slip pad can prevent the worktable from slipping, so that the components on the worktable can perform better when in use and avoid the worktable from shaking during use, which would lead to the instability of the components on the worktable.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0012] 1. When the reverse osmosis membrane nonwoven fabric needs to play a buffering role, this utility model first rotates the screw sleeve. The threaded groove on the slide rod can limit the sliding sleeve. The upward movement of the sliding sleeve can limit the shock absorption force of the shock-absorbing spring. When the reverse osmosis membrane nonwoven fabric is transmitted through the buffer roller, the impact force is transmitted to the sliding sleeve through the buffer roller. At this time, the sliding sleeve will move on the slide rod. The impact force can be transmitted to the shock-absorbing spring through the sliding sleeve. The shock-absorbing spring can reduce the impact force to a minimum. In this way, the reverse osmosis membrane nonwoven fabric has a better effect when winding. It avoids the reverse osmosis membrane nonwoven fabric from having no buffer structure, which would cause the reverse osmosis membrane nonwoven fabric to wrinkle, tensile damage or even breakage during the winding process.

[0013] 2. When it is necessary to wind up the nonwoven fabric of the reverse osmosis membrane, the winding roller is first installed on the first mounting plate and the second mounting plate. At this time, the motor runs and drives the second mounting plate to rotate. The winding roller rotates in cooperation with the second mounting plate and the first mounting plate, and then the nonwoven fabric of the reverse osmosis membrane can be wound up by the winding roller.

[0014] Anti-slip mats can prevent the workbench from slipping, which makes the parts on the workbench work better and avoids the workbench from shaking during use, thus preventing the parts on the workbench from being unstable.

[0015] The guide roller can limit the movement of the reverse osmosis membrane nonwoven fabric during winding, thus preventing the reverse osmosis membrane nonwoven fabric from shifting during winding and thus avoiding poor winding effect. Attached Figure Description

[0023] The following drawings will disclose several embodiments of this utility model. For clarity, many practical details will be described in the following description. However, it should be understood that these practical details should not be used to limit this utility model. That is, in some embodiments of this utility model, these practical details are not essential. In addition, for the sake of simplicity, some conventional structures and components will be shown in the drawings in a simple schematic manner.

[0024] Please see Figure 1-5 This utility model discloses a high-speed winding device for reverse osmosis membrane nonwoven fabric with a flexible buffer structure. It includes a worktable 1, a winding assembly 2 on the left side of the top of the worktable 1, two guide assemblies 4 on the right side of the top of the worktable 1, and a buffer assembly 3 on one side of each guide assembly 4. The buffer assembly 3 includes a frame 301, the bottom of which is fixedly connected to the worktable 1. Slide rods 304 are provided on both sides of the inner cavity of the frame 301. Slide sleeves 303 are movably fitted onto the surface of the slide rods 304. A shock-absorbing spring 306 is provided at the connection between the top of the slide sleeve 303 and the frame 301, and the shock-absorbing spring 306 is fitted onto the surface of the slide rod 304. A threaded sleeve 308 is fitted onto the bottom of the surface of the slide rod 304, and a threaded groove 309 adapted to the threaded sleeve 308 is opened at the bottom of the surface of the slide rod 304. A rotatable connection is made between one side of each of the two slide sleeves 303 and the other side of the frame 301. The buffer roller 305 is used in this invention to buffer the reverse osmosis membrane nonwoven fabric. First, the screw sleeve 308 is rotated, and the sliding sleeve 303 is limited by the threaded groove 309 on the sliding rod 304. The upward movement of the sliding sleeve 303 can limit the shock absorption force of the shock-absorbing spring 306. When the reverse osmosis membrane nonwoven fabric is transmitted through the buffer roller 305, the impact force is transmitted to the sliding sleeve 303 through the buffer roller 305. At this time, the sliding sleeve 303 will move on the sliding rod 304, and the impact force can be transmitted to the shock-absorbing spring 306 through the sliding sleeve 303. The shock-absorbing spring 306 can reduce the impact force to a minimum. In this way, the reverse osmosis membrane nonwoven fabric has a better effect when winding, avoiding the reverse osmosis membrane nonwoven fabric that does not have a buffer structure, which would cause surface wrinkling, tensile damage or even breakage during the winding process.

[0025] The winding assembly 2 includes a concave plate 201, the bottom of which is fixedly connected to the workbench 1. A first mounting plate 202 is movably connected to one end of the inner cavity of the concave plate 201, and a motor 204 is provided at the other end of the concave plate 201. The output end of the motor 204 extends through and into the inner cavity of the concave plate 201, where a second mounting plate 203 is provided. When it is necessary to wind up the reverse osmosis membrane nonwoven fabric, the winding roller is first installed on the first mounting plate 202 and the second mounting plate 203. At this time, the motor 204 runs, driving the second mounting plate 203 to rotate. The second mounting plate 203 and the first mounting plate 202 cooperate with the winding roller to rotate, thereby winding up the reverse osmosis membrane nonwoven fabric.

[0026] The material guiding assembly 4 includes two connecting plates 401, and the bottom of the two connecting plates 401 is fixedly connected to the worktable 1. A guide roller 402 is rotatably connected to one side of the two connecting plates 401. The guide roller 402 can limit the movement of the reverse osmosis membrane nonwoven fabric when it is being wound up, thus avoiding the reverse osmosis membrane nonwoven fabric from shifting during winding, which would result in poor winding effect.

[0027] The surface of the threaded sleeve 308 is provided with anti-slip threads, and the threaded sleeve 308 is located below the sliding sleeve 303.

[0028] A movable rod 307 is fixedly connected to the outer side of the sliding sleeve 303, and sliding grooves 302 adapted to the movable rod 307 are provided on both sides of the inner cavity of the frame 301.

[0029] The bottom of the workbench 1 is provided with an anti-slip pad 5, and the bottom of the anti-slip pad 5 is provided with anti-slip particles. The anti-slip pad 5 can prevent the workbench 1 from slipping, so that the parts on the workbench 1 can perform better when in use, and avoid the workbench 1 from shaking during use, which would lead to the instability of the parts on the workbench 1.

[0030] When using this utility model: When the reverse osmosis membrane nonwoven fabric needs to play a buffering role, first rotate the screw sleeve 308. The threaded groove 309 on the slide rod 304 can limit the slide sleeve 303. The upward movement of the slide sleeve 303 can limit the shock absorption force of the shock-absorbing spring 306. When the reverse osmosis membrane nonwoven fabric is transmitted through the buffer roller 305, the impact force is transmitted to the slide sleeve 303 through the buffer roller 305. At this time, the slide sleeve 303 will move on the slide rod 304. The impact force can be transmitted to the shock-absorbing spring 306 through the slide sleeve 303. The shock-absorbing spring 306 can reduce the impact force to a minimum. In this way, the reverse osmosis membrane nonwoven fabric has a better effect when winding. It avoids the reverse osmosis membrane nonwoven fabric from having no buffer structure, which would cause the reverse osmosis membrane nonwoven fabric to wrinkle, tensile damage or even breakage during the winding process.
