Description

Technical Field

[0001] This utility model belongs to the field of RO reverse osmosis membrane treatment technology, and in particular relates to an RO reverse osmosis flow guide cloth tension control device. Background Technology

[0002] RO reverse osmosis membranes are core components in the water treatment field. During their production, the flow guide cloth (also known as "mesh" or "support layer") is a key material for spiral wound membrane elements and requires high-precision tension control during the winding process. The tension stability of the flow guide cloth directly affects the sealing performance, antifouling ability, and service life of the membrane element: insufficient tension can easily lead to fabric wrinkles and interlayer slippage, resulting in a decrease in desalination rate; excessive tension will stretch the fabric fibers or even tear them, leading to an increase in scrap rate.

[0003] Based on the technical effects of the existing technologies and solutions, there are still areas that need optimization: the existing tension control requires the use of detection instruments for detection and control. If the detection instruments are affected by moisture, the sensitivity will decrease, resulting in unstable tension control; or if a single floating roller is used, the take-up roller that works with it cannot be adjusted in real time according to the tension of the guide cloth, which will also lead to unstable tension control during take-up. Utility Model Content

[0004] To address the problems existing in the prior art, this utility model provides a tension control device for RO reverse osmosis guide cloth. Existing tension control requires the use of detection instruments for detection and control. If the detection instruments are affected by moisture, the sensitivity will decrease, resulting in unstable tension control. Alternatively, if a single floating roller is used, the take-up roller that works with it cannot be adjusted in real time according to the tension of the guide cloth, which will also lead to unstable tension control during take-up.

[0005] This invention is achieved as follows: an RO reverse osmosis guide cloth tension control device, comprising,

[0006] A support mechanism includes a support plate, with support columns at both ends of the top of the support plate, a floating component on the opposite side of the support columns, and a transmission component on one side of the floating component.

[0007] A winding mechanism includes support members disposed at both ends of the top of a support plate, and a winding assembly is disposed on the opposite side of the support members.

[0008] In a preferred embodiment of this invention, the floating component includes a floating groove formed on the surface of the support column, a floating block slidably connected to the surface of the floating groove, a floating column provided on the inner wall of the floating block, a floating roller provided on the opposite side of the floating column, and an adjustment component provided at the bottom of the floating block. The floating component can respond in real time to changes in the tension of the guide cloth by sliding the floating roller in the floating groove, and achieve adaptive tension balance through the linkage of the floating block.

[0009] In a preferred embodiment of this invention, the transmission component includes a transmission rod disposed on one side of the floating column. The outer side of the transmission rod is slidably connected to the inner wall of the positioning block, and the rear side of the positioning block is fixedly connected to the front side of the support column. The right side of the transmission rod is provided with a plurality of teeth. The transmission component utilizes the tooth structure of the transmission rod to convert the displacement of the floating roller into a mechanical transmission signal, providing a basis for linkage control of tension adjustment at the winding end.

[0010] In a preferred embodiment of this invention, the winding assembly includes a winding roller disposed on the opposite side of the support member. A motor for transmission is disposed on the front side of the winding roller, and the rear side of the motor is fixedly connected to the front side of the rotating plate. Two rotating plates are disposed and evenly distributed on the opposite side of the support member. A support ring is disposed on the opposite side of the rotating plate. The winding assembly drives the winding roller through the motor, and combined with the support and positioning of the rotating plate, realizes the automated transmission of winding of the guide cloth, ensuring winding efficiency and stability.

[0011] In a preferred embodiment of this invention, the adjusting component includes an adjusting groove formed on the surface of the floating groove. An adjusting block is slidably connected to the surface of the adjusting groove. The opposite side of each adjusting block is fixedly connected to the opposite side of the floating block. A spring is provided at the bottom of the floating block, and a damper is provided inside the spring. The bottoms of both the spring and the damper are fixedly connected to the surface of the adjusting groove. The combination of the spring and the damper in the adjusting component provides elastic buffering and damping suppression for the floating roller, avoiding fabric stretching damage or loosening caused by sudden tension changes.

[0012] In a preferred embodiment of this invention, rotating rods extend through both the front and rear sides of the support member and the rotating plate. Gears are fixedly connected to the outer side of the rotating rods, and the surface of the gears meshes with the teeth. The meshing transmission between the gears and the teeth converts the vertical displacement of the floating roller into the rotational adjustment of the rotating rod at the winding end, thereby realizing the mechanical linkage control of tension changes and winding speed.

[0013] As a preferred embodiment of this utility model, a torsion spring is provided on the rear side of the gear, and the rear side of the torsion spring is fixedly connected to the front side of the support member. The torsion spring and the rotating rod are sleeved together. The torsion spring, through the elastic restoring force sleeved on the rotating rod, assists the gear to automatically reset after tension adjustment, maintains the dynamic balance of the system and reduces mechanical lag.

[0014] As a preferred embodiment of this utility model, the front side of the take-up roller is provided with an installation groove, and an installation block is slidably connected to the surface of the installation groove. The front side of the installation block is drivenly connected to the output end of the motor. The sliding connection structure between the installation groove and the installation block facilitates the quick disassembly and maintenance of the take-up roller, improving the ease of use and maintenance efficiency of the device.

[0015] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0016] This invention, by setting up a floating component, a transmission component, and an adjustment component, allows the floating roller to be squeezed or pushed up and down by a spring when tension changes cause it to be squeezed. The transmission component converts the up and down displacement into rotational motion through the meshing of teeth and gears, directly driving the position adjustment of the take-up roller, so that it can adapt to the tension change and change the take-up position, thus realizing dynamic adaptive adjustment of tension and take-up. The setting of mounting groove and mounting block facilitates the disassembly, assembly, and maintenance of the take-up roller. Attached Figure Description

[0025] The structure of this utility model will now be described in detail with reference to the accompanying drawings.

[0026] like Figures 1 to 6 As shown in the figure, an embodiment of the present invention provides an RO reverse osmosis guide cloth tension control device, comprising,

[0027] The support mechanism 100 includes a support plate 101, with support columns 102 at both ends of the top of the support plate 101, a floating component 103 on the opposite side of the support column 102, and a transmission component 104 on one side of the floating component 103.

[0028] The winding mechanism 200 includes support members 201 disposed at both ends of the top of the support plate 101, and a winding assembly 202 disposed on the opposite side of the support members 201.

[0029] refer to Figures 1-4 The floating component 103 includes a floating groove 103a formed on the surface of the support column 102, a floating block 103b slidably connected to the surface of the floating groove 103a, a floating column 103c provided on the inner wall of the floating block 103b, a floating roller 103d provided on the opposite side of the floating column 103c, and an adjusting component 105 provided at the bottom of the floating block 103b.

[0030] Using the above scheme: the floating component 103 can respond to the tension change of the guide cloth in real time by sliding the floating roller 103d in the floating groove 103a, and achieve adaptive tension balance through the linkage of the floating block 103b.

[0031] refer to Figures 1-5The transmission component 104 includes a transmission rod 104a disposed on one side of the floating column 103c. The outer side of the transmission rod 104a is slidably connected to the inner wall of the positioning block 104b. The rear side of the positioning block 104b is fixedly connected to the front side of the support column 102. A plurality of teeth 104c are provided on the right side of the transmission rod 104a.

[0032] Using the above scheme: the transmission component 104 uses the tooth 104c structure of the transmission rod 104a to convert the displacement of the floating roller 103d into a mechanical transmission signal, providing a basis for linkage control for tension adjustment at the winding end.

[0033] refer to Figure 1 , 6 The winding assembly 202 includes a winding roller 202a disposed on the opposite side of the support member 201. A motor 202b for transmission is disposed on the front side of the winding roller 202a. The rear side of the motor 202b is fixedly connected to the front side of the rotating plate 202c. Two rotating plates 202c are disposed and evenly distributed on the opposite side of the support member 201. A support ring 202d is disposed on the opposite side of the rotating plate 202c.

[0034] Using the above solution: the winding assembly 202 drives the winding roller 202a through the motor 202b, and combined with the support and positioning of the rotating plate 202c, realizes the automated transmission of the guide cloth winding, and ensures winding efficiency and stability.

[0035] refer to Figure 1 , 2 The adjusting component 105 includes an adjusting groove 105a formed on the surface of the floating groove 103a. An adjusting block 105b is slidably connected to the surface of the adjusting groove 105a. The opposite side of the adjusting block 105b is fixedly connected to the opposite side of the floating block 103b. A spring 105c is provided at the bottom of the floating block 103b. A damper 105d is provided inside the spring 105c. The bottoms of the spring 105c and the damper 105d are fixedly connected to the surface of the adjusting groove 105a.

[0036] The above solution is adopted: the spring 105c in the adjusting component 105 is combined with the damper 105d to provide elastic buffering and damping suppression for the floating roller 103d, so as to avoid the stretching damage or loosening of the fabric caused by sudden tension changes.

[0037] refer to Figure 1 , 5 Rotating rods 203 extend through both the front and rear sides of the support member 201 and the rotating plate 202c. A gear 204 is fixedly connected to the outer side of the rotating rod 203, and the surface of the gear 204 meshes with the teeth 104c.

[0038] The above scheme is adopted: the meshing transmission of gear 204 and tooth 104c converts the vertical displacement of floating roller 103d into the rotation adjustment of winding end rotating rod 203, thereby realizing the mechanical linkage control of tension change and winding speed.

[0039] refer to Figure 5 A torsion spring 205 is provided on the rear side of the gear 204. The rear side of the torsion spring 205 is fixedly connected to the front side of the support member 201. The torsion spring 205 and the rotating rod 203 are sleeved together.

[0040] Using the above scheme: the torsion spring 205, through the elastic restoring force sleeved on the rotating rod 203, enables the auxiliary gear 204 to automatically reset after tension adjustment, maintaining the dynamic balance of the system and reducing mechanical lag.

[0041] refer to Figure 1 , 6 The front side of the take-up roller 202a has an installation groove 206, and an installation block 207 is slidably connected to the surface of the installation groove 206. The front side of the installation block 207 is connected to the output end of the motor 202b.

[0042] The above solution, with its sliding connection structure between the mounting groove 206 and the mounting block 207, facilitates the quick disassembly and maintenance of the winding roller 202a, improving the ease of use and maintenance efficiency of the device.

[0043] The working principle of this utility model:

[0044] When using a tension control device;

[0045] First, when the tension of the guide cloth changes, the floating roller 103d is subjected to tension or thrust, which drives the floating block 103b to slide up and down along the floating groove 103a of the support column 102. At this time, the spring 105c in the adjusting component 105 provides elastic support, and the damper 105d suppresses oscillation, forming a preliminary buffer. Second, the displacement of the floating column 103c gives the tooth 104c structure conversion signal to the surface of the transmission rod 104a, and the lateral movement of the transmission rod 104a drives the gear 204 meshing with it to rotate.

[0046] When gear 204 transmits rotational motion to rotating plate 202c via rotating rod 203, the elastic reset function of torsion spring 205 ensures transmission accuracy and provides a certain rotation limit. Rotating plate 202c adapts the tension state of take-up roller 202a to guide cloth according to the rotation angle of rotating rod 203, thereby achieving real-time matching of take-up and tension.

[0047] The sliding of the mounting groove 206 and the mounting block 207 allows for quick replacement of the take-up roller 202a. During maintenance, disassembly can be completed simply by pulling the mounting block 207 laterally. The support ring 202d ensures that the take-up roller 202a is more stable during rotation and will not slip due to the mounting groove 206 and the mounting block 207. When it is necessary to disassemble or assemble the take-up roller 202a, the mounting groove 206 should be facing the bottom.

[0048] In summary: Existing tension control devices for RO reverse osmosis guide cloth require the use of detection instruments for detection and control. If the detection instruments are affected by moisture, their sensitivity will decrease, leading to unstable tension control. Alternatively, if a single floating roller is used, the take-up roller that works with it cannot adjust in real time according to the tension of the guide cloth, which will also lead to unstable tension control during take-up.
