TECHNICAL FIELD

[0001] The present application relates to the technical field of filter cloth conveying, and in particular to an electrostatic adsorption type filter cloth conveying platform and a winding device. BACKGROUND

[0002] With the continuous development of industrial production, the efficiency and stability of filter cloth conveying are increasingly required. A high-efficiency and stable filter cloth conveying system can improve the efficiency of the entire production process, reduce production costs, and is of great significance to the development of related industries. It is widely used in chemical, food, pharmaceutical and other industries. In the production process of these industries, the conveying of filter cloth directly affects the quality of products and the continuity of production.

[0003] In the filter cloth conveying technology in the related art, in order to realize the carrying and conveying of filter cloth, a traditional conveying device is usually used to move the filter cloth to a specified position, for example, a plurality of upper and lower opposite conveying rollers are used to clamp the filter cloth and send it to the specified position. Another way is to use a conveying belt to convey the filter cloth, and the filter cloth is placed on the conveying belt, and the rotation of the conveying belt is relied on to realize the movement of the filter cloth. These methods meet the needs of filter cloth conveying to varying degrees.

[0004] However, the above-mentioned filter cloth conveying means has obvious defects. The traditional mechanical device is not flexible enough in controlling the tension of the filter cloth when conveying the filter cloth, which can easily cause wrinkles, deviation and other problems of the filter cloth during conveying, affecting the conveying effect. SUMMARY

[0005] In order to flexibly increase the surface tension of the filter cloth when conveying the filter cloth, the present application provides an electrostatic adsorption type filter cloth conveying platform.

[0006] In a first aspect, the electrostatic adsorption type filter cloth conveying platform provided by the present application adopts the following technical solution: An electrostatic adsorption type filter cloth conveying platform, comprising a workbench, the workbench comprising a plurality of load tables and a plurality of resistance tables arranged in sequence along a first direction, the load tables being used to carry the filter cloth in motion, and the resistance tables being used to grab the filter cloth in motion to increase the surface tension of the filter cloth; a carrying mechanism, the carrying mechanism comprising a plurality of moving units, the moving units comprising a grabbing mechanism capable of reciprocating along the first direction, the grabbing mechanism being used to grab the filter cloth and carry the filter cloth along the first direction.

[0007] By adopting the above technical solution, the load table of the workbench can carry the filter cloth in motion, the resistance table can grab the filter cloth in motion to increase the surface tension thereof, and the grabbing mechanism of the moving unit of the carrying mechanism can reciprocate along the first direction to grab and carry the filter cloth to move, thereby realizing the conveying of the filter cloth on the workbench.

[0008] Optionally, the gripping mechanism includes a first electrostatic generator.

[0009] By adopting the above technical solution, the first electrostatic generator rod is used to generate electrostatic adsorption of the filter cloth, thereby realizing the gripping of the filter cloth and facilitating the transport mechanism to carry the filter cloth along the first direction.

[0010] Optionally, the conveying mechanism further includes a track extending along a first direction, the track being equidistantly arranged along a second direction perpendicular to the first direction, and the moving unit further includes an electric slide and an electric turntable, the electric slide being slidably connected to the track, and the gripping mechanism being connected to the electric slide via the electric turntable.

[0011] By adopting the above technical solution, the track extends along the first direction and is equidistantly set in the second direction, providing a stable moving path for the moving unit; the electric slide is slidably connected to the track, enabling the moving unit to move back and forth along the first direction; the electric turntable connects the gripping mechanism and the electric slide, enabling the gripping mechanism to rotate, thereby changing the direction of the first electrostatic generator rod, which facilitates the adsorption of filter cloth and subsequent operations.

[0012] Optionally, the sum of the length and width of the first electrostatic generator is matched with twice the distance between the central axes of any two adjacent tracks, the number of tracks is not less than four, and the distance between the central axes of the two tracks furthest apart is not less than the width of the platform.

[0013] By adopting the above technical solution, the spacing between the first electrostatic generator and the adjacent track is matched, which can ensure that the first electrostatic generator of each moving unit is reasonably arranged during operation and avoid interference; with no less than 4 tracks and the distance between the farthest tracks is not less than the width of the platform, the requirements for filter cloth conveying can be met, and the moving units at multiple tracks can work synchronously, thereby improving the efficiency of filter cloth conveying.

[0014] Optionally, the transport stage includes a second electrostatic generator rod, the length of which is equal to the width of the stage.

[0015] By adopting the above technical solution, an obstruction platform including a second electrostatic generator is set in the electrostatic adsorption filter cloth conveying platform, and the length of the second electrostatic generator is equal to the width of the platform. This allows the obstruction platform to better grasp the filter cloth in motion and effectively increase the surface tension of the filter cloth.

[0016] Optionally, the platform is an air-floating platform.

[0017] By adopting the above technical solution, the air flotation platform can be used to support the moving filter cloth, which can reduce the friction between the filter cloth and the platform, making the movement of the filter cloth smoother, reducing the risk of filter cloth damage, and also helping to improve the stability and efficiency of filter cloth conveying.

[0018] Optionally, a tension monitoring mechanism is also included. The air source temperature of the air flotation platform is lower than the ambient temperature. The tension monitoring mechanism includes a control component and multiple infrared thermal imaging cameras. The infrared thermal imaging cameras are located above the workbench. The control component is simultaneously connected to the infrared thermal imaging cameras and the obstruction platform. The infrared thermal imaging cameras are used to capture the temperature field on the surface of the filter cloth. The control component is used to infer the tension distribution state from the changes in the temperature field on the filter cloth surface and control the obstruction platform according to the tension distribution.

[0019] By adopting the above technical solution and setting up a tension monitoring mechanism, the temperature field of the filter cloth surface changes due to the influence of tension, and the temperature field of the filter cloth surface is captured by an infrared thermal imaging camera. The control component can infer the tension distribution state based on the temperature field change, and then control the resistance stage according to the tension distribution to realize the monitoring and adjustment of the filter cloth tension.

[0020] Optionally, the working plane of the second electrostatic generator is kept horizontal with the surface of the air flotation platform, and the distance between the working planes of the first and second electrostatic generators is equal to the working height of the air flotation platform.

[0021] By adopting the above technical solution, the working plane of the second electrostatic generator is lower than the working height of the air flotation platform. When the second electrostatic generator is working, this distance allows the second electrostatic generator to pull the filter cloth with a small force to increase the tension, without affecting the normal transport of the filter cloth by the first electrostatic generator.

[0022] Secondly, this application provides a winding device, which adopts the following technical solution: A winding device includes an electrostatic adsorption filter cloth conveying platform as described above.

[0023] By adopting the above technical solution, the winding device can use the electrostatic adsorption filter cloth conveying platform to convey the filter cloth to the winding terminal, thereby maintaining uniform tension and stable operation of the filter cloth during the winding process.

[0024] In summary, this application includes at least one of the following beneficial technical effects: 1. The platform supports the moving filter cloth, while the conveying platform grips the moving filter cloth to increase surface tension, thus preventing wrinkles and deviations during filter cloth conveying and improving conveying efficiency. 2. The gripping mechanism of the conveying mechanism grips the filter cloth and carries it along the first direction to realize the filter cloth conveying, which avoids damage to the filter cloth caused by traditional mechanical conveying devices and can adapt to complex conveying needs. 3. Multiple moving units can work synchronously or alternately to circulate and transport the filter cloth, thereby improving the filter cloth transport efficiency and meeting production requirements.

[0028] The following is in conjunction with the appendix Figures 1-2 This application will be described in further detail.

[0029] This application discloses an electrostatic adsorption filter cloth conveying platform.

[0030] like Figure 1 and Figure 2 As shown, the electrostatic adsorption filter cloth conveying platform includes a worktable and a conveying mechanism. The worktable and the conveying mechanism work together to achieve efficient and stable conveying of the filter cloth. The worktable can bear and adjust the tension of the filter cloth, while the conveying mechanism can grasp and move the filter cloth. The two work together to improve the efficiency and stability of filter cloth conveying.

[0031] like Figure 1 and Figure 2 As shown, the worktable includes multiple carrying platforms and multiple obstruction platforms arranged sequentially along a first direction. The carrying platforms are used to support the moving filter cloth. These platforms can be air-float platforms 1, which suspend the filter cloth using the buoyancy of gas, reducing friction between the filter cloth and the carrying platforms and preventing damage. The air source temperature of the air-float platform 1 is lower than the ambient temperature, allowing the filter cloth to maintain a certain temperature difference during transport, which is beneficial for subsequent monitoring of the filter cloth tension using an infrared thermal imaging camera 7. The obstruction platforms are used to grip the moving filter cloth to increase its surface tension. Each obstruction platform includes a second electrostatic generator 2, the length of which is equal to the width of the carrying platform. This ensures that the second electrostatic generator 2 can fully cover the filter cloth, effectively increasing its surface tension. The working plane of the second electrostatic generator 2 is level with the surface of the air-float platform 1. When the second electrostatic generator 2 is working, this distance allows it to gently pull the filter cloth to change its tension without affecting the normal transport of the filter cloth by the first electrostatic generator 3.

[0032] like Figure 1 and Figure 2As shown, the conveying mechanism includes multiple moving units, each including a gripping mechanism capable of reciprocating along a first direction. The gripping mechanism grips the filter cloth and carries it along the first direction. The gripping mechanism includes a first electrostatic generator 3, which grips the filter cloth via electrostatic adsorption, offering advantages over traditional mechanical gripping methods such as stable gripping and no damage to the filter cloth. The conveying mechanism also includes tracks 4 extending along the first direction. These tracks 4 are equidistantly arranged along a second direction perpendicular to the first direction, with at least four tracks. The distance between the central axes of the two furthest tracks 4 is not less than the width of the platform, ensuring the conveying mechanism can cover the entire platform and achieve comprehensive filter cloth transport. The tracks 4 can be relatively fixed to the worktable via a frame 8. The moving unit also includes an electric slide 5 and an electric turntable 6. The electric slide 5 is slidably connected to the tracks 4, allowing it to move smoothly on the tracks 4 and providing power for filter cloth transport. The gripping mechanism is connected to the electric slide table 5 via an electric turntable 6. The electric turntable 6 can rotate the first electrostatic generator 3, thereby changing its direction to adapt to different working requirements. The sum of the length and width of the first electrostatic generator 3 matches twice the distance between the central axes of any two adjacent tracks 4. This ensures that the first electrostatic generators 3 on different tracks 4 can be rationally arranged and avoid mutual interference. The electric slide table 5 and the electric turntable 6 are common technologies in this field, so their structures will not be described in detail here.

[0033] like Figure 1 and Figure 2 As shown, this embodiment also includes a tension monitoring mechanism, which includes a control component and multiple infrared thermal imaging cameras 7. The infrared thermal imaging cameras 7 are located above the worktable. In this embodiment, the infrared thermal imaging cameras 7 are fixed to the frame 8, and the number of infrared thermal imaging cameras 7 is multiple and arranged in an array. The control component is simultaneously connected to the infrared thermal imaging cameras 7 and the conveying platform. The infrared thermal imaging cameras 7 are used to capture the temperature field on the surface of the filter cloth. Since the air source temperature of the air flotation platform 1 is lower than the ambient temperature, the temperature distribution of the filter cloth will be different under different tension states. The control component can infer the tension distribution state by the change in the temperature field on the surface of the filter cloth, and control the conveying platform according to the tension distribution, thereby realizing the automatic adjustment of the filter cloth tension and ensuring the stability of the filter cloth conveying.

[0034] In actual operation, there are multiple tracks 4. These multiple tracks 4 are divided into two groups. Starting from one side of the multiple tracks 4, the tracks 4 with odd numbers are in one group, and the tracks 4 with even numbers are in the other group. The moving units located at the same group of tracks 4 work synchronously. For example, in standby mode, the moving units at odd-numbered tracks 4 are located at the end of track 4, and the moving units at even-numbered tracks 4 are located at the beginning of track 4, with the first electrostatic generator rods 3 parallel to the first direction. Before starting work, the first electrostatic generator rods 3 of the moving units at odd-numbered tracks 4 rotate to be parallel to the second direction under the action of the electric turntable 6. When starting work, the first electrostatic generator rods 3 of the moving units at odd-numbered tracks 4 begin to adsorb the filter cloth and carry it along the first direction from the end of track 4 to the beginning of track 4. At the same time, the moving units at even-numbered tracks 4 quickly move along the first direction from the beginning of track 4 to the end of track 4. The direction of the first electrostatic generator rods 3 of the moving units at even-numbered tracks 4 remains parallel to the first direction and from the odd-numbered tracks 4... The first electrostatic generator 3 of the moving unit passes through the gap of the first electrostatic generator 3 at the even-numbered track 4; then, the moving unit at the even-numbered track 4 arrives at the end of track 4 first, and at the same time, the first electrostatic generator 3 of the moving unit at the even-numbered track 4 rotates to be parallel to the second direction under the action of the electric turntable 6; then, the first electrostatic generator 3 of the moving unit at the even-numbered track 4 starts to work to adsorb the filter cloth, and carries the filter cloth along the first direction from the end of track 4 to the beginning of track 4. During its movement, the moving unit at the odd-numbered track 4 carries the filter cloth to the beginning of track 4 and releases the filter cloth; then, the first electrostatic generator 3 of the moving unit at the odd-numbered track 4 rotates to be parallel to the first direction under the action of the electric turntable 6, and quickly moves from the beginning of track 4 to the end of track 4; then the cycle begins.

[0035] The implementation principle of the electrostatic adsorption filter cloth conveying platform in this application is as follows: This application uses electrostatic adsorption to grasp the filter cloth, avoiding the damage caused to the filter cloth by traditional mechanical grasping methods and improving the service life of the filter cloth. The design of the multi-track 4 and the synchronous operation of the moving unit make the filter cloth conveying more efficient. The use of the air flotation platform 1 reduces the friction between the filter cloth and the platform, further protecting the filter cloth. The tension monitoring mechanism can monitor the tension of the filter cloth in real time and automatically adjust it according to the tension distribution, ensuring the stability of the filter cloth conveying.

[0036] This application also discloses a winding device.

[0037] The winding device includes the electrostatic adsorption filter cloth conveying platform described in the above embodiments. The winding device can deliver the filter cloth to the winding terminal for winding through the electrostatic adsorption filter cloth conveying platform, maintaining the flatness and tension uniformity of the filter cloth during the conveying process, and ensuring that no wrinkles or uneven tension occur during the winding process.

[0038] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
