Description

Technical Field

[0001] This invention relates to the field of filter screen manufacturing equipment technology, and more specifically, to a production process for filter screen manufacturing equipment and its filter screen. Background Technology

[0002] In the traditional filter screen production process, there are many problems: First, in the filter screen raw material transportation stage, due to the lack of an effective tension adjustment device, the filter screen raw material is prone to loosening and wrinkling during transportation, resulting in unstable and discontinuous material transportation, which in turn affects the quality of subsequent cutting and forming, making the cut mesh structure size inaccurate and the shape irregular, thus reducing the filtration performance of the filter screen.

[0003] Secondly, regarding the cutting and forming process, traditional cutting equipment lacks sufficient guiding precision. The cutting mold is prone to shifting during movement, resulting in the upper and lower molds not fitting precisely. This makes it impossible to cut a mesh structure that meets the preset specifications in one go, requiring multiple cuts or manual corrections, which increases production time and costs while reducing production efficiency. Moreover, the transfer process of the formed mesh lacks automation and precise positioning, which can easily cause damage and positional deviations to the mesh, affecting the subsequent assembly quality. Summary of the Invention

[0004] In view of the shortcomings of the existing technology, the purpose of this invention is to provide a production process for a high-efficiency, precise and automated filter manufacturing equipment and its filter.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a production process for a filter screen manufacturing equipment, including the following specific operation steps: S1, raw material preparation: placing the filter screen raw material on the tray support of the feeding and conveying mechanism, adjusting the tension adjustment component so that the filter screen raw material maintains a preset tension during the conveying process, and can be stably and continuously output to the cutting mechanism; S2. Mesh Cutting and Forming: The drive device drives the upper mold to move vertically downwards and precisely fits with the lower mold fixed on the worktable. Using the matching forming surfaces of the upper and lower molds, the filter screen is cut to the preset diameter size in one go. During the cutting process, the guide rod precisely restricts the movement direction of the cutting mold, and the formed mesh fabric is pressed against the first equidistant rotating frame. At the same time, it is rotated to the trimming station. After being trimmed by the edge trimming gun, it is placed in the second rotating bracket and rotated again to the assembly station. Then, the sliding seat carries the feeding and transporting mechanism to move back and forth along the length direction, entering the cutting cycle, forming an equidistant and swaying cutting effect. S3. Frame Forming: The annular workpiece is placed into the loading cylinder and enters the annular stretching die holder in an orderly manner through the transport track. The transmission component of the stretching and shaping mechanism is activated. The second cylinder drives the sliding platform to move along the width direction of the guide rail, and the first cylinder drives the horizontal moving platform to move along the length direction of the guide rail. The linkage gripper assembly is precisely moved above the annular stretching die holder and is in a standby state. The stamping gun in the annular stretching die holder is activated to precisely extrude and shape the annular workpiece, completing one shaping operation. S4. Secondary cutting and shaping of the space frame: The pneumatic clamp of the linkage gripper assembly precisely clamps the space frame and transfers it to the bottom of the punching gun. The formed space frame is then cut and shaped a second time. The cut space frame is then smoothly transferred to the next assembly station by the pneumatic clamp again. S5. Assembly and Forming: The mesh fabric delivered to the assembly station is precisely aligned with the mesh frame that has been transferred to the position. The assembly top rod is raised to perform preliminary positioning of the mesh fabric and the mesh frame. The pressing component is activated, and the drive motor drives the pressing mold base to move vertically downward. The pressing table works together to evenly press the connection between the mesh fabric and the mesh frame, completing the overall riveting and forming operation of the filter screen.

[0006] The present invention is further configured such that: the first equidistant rotating bracket and the second equidistant rotating bracket in S2 are controlled to rotate by a first motor and a second motor, respectively; and the outer rotating shafts of the first motor and the second motor are provided with rotating scales, and a positioning detector adapted to the rotating scales is provided on one side of the rotating scales to detect whether the rotation is in place. The specific steps are as follows: S21. When the first motor and the second motor drive the first equidistant rotating bracket and the second equidistant rotating bracket to rotate respectively, the positioning detector will continuously monitor the rotation scale and accurately identify the position change of the rotation scale. Once the rotating shaft fails to rotate to the preset scale position, the positioning detector will immediately capture this information and respond quickly. It will send a specific signal to the entire control system to stop the machine operation and correct the rotating bracket.

[0007] The present invention is further configured such that: the assembly station in S4 is also equipped with an infrared detector for detecting objects, and the specific operation is as follows: S41. When an installation accessory enters the detection range, the infrared light will be reflected or blocked, and the signal will be interrupted, indicating that the installation accessory is in place and waiting for the next instruction; if the infrared light signal is not interrupted, it means that the installation accessory has not been transmitted to the correct position, and the signal will be transmitted to the control system, and the installation accessory needs to be picked up and transmitted again.

[0008] This application also provides a filter screen manufactured according to the production process of a filter screen manufacturing equipment, including an annular mesh frame and a mesh fabric pressed and fixed to the open end of the annular mesh frame. The mesh frame has an inner wall and an outer wall, and the mesh fabric is fixedly connected by the inner wall and the outer wall at the opening pressing against each other.

[0009] The present invention is further configured such that the diameter of the mesh frame is 0.9-0.95 times the depth of the mesh.

[0010] 1. In the raw material preparation stage, by placing the filter screen material on the tray support of the feeding and conveying mechanism and adjusting the tension adjustment component, the filter screen material can maintain the preset tension during the conveying process, ensuring the integrity and uniformity of the mesh during cutting and reducing the defect rate caused by unstable raw material conveying. The drive device drives the upper and lower dies to precisely fit together, cutting the mesh diameter in one go. The first equidistant rotating support ensures cutting accuracy, and automated transfer and cyclic operation improve production efficiency. The annular workpiece enters the annular stamping die base via the transport track. The stretching and shaping mechanism is precisely positioned, and the stamping gun precisely shapes it, ensuring that the mesh frame specifications meet the requirements. The pneumatic clamp precisely transfers the mesh frame for secondary cutting and shaping, eliminating the deviation of the first forming and improving the overall quality of the mesh frame. The mesh and mesh frame are precisely aligned, the top rod is installed for positioning, and the clamping component is evenly pressed, enhancing the structural strength and stability of the filter screen and extending its service life.

[0011] 2. In the cutting and forming stage of the filter screen manufacturing equipment, the first and second equidistant rotating supports are controlled by the first and second motors, respectively. The rotating shaft on the outside of the motor is equipped with a rotation scale and a positioning detector. The positioning detector continuously monitors the rotation scale and accurately identifies position changes, which can ensure that the rotating frame rotates to the preset precise position, improve the accuracy of the mesh transfer, and thus improve the production precision and quality of the filter screen. Once the rotating shaft does not reach the preset scale, the detector can promptly provide feedback, stop the machine operation and correct the rotating frame, enhance production stability, reduce failures and losses, improve production efficiency, reduce labor costs, reduce human interference, and ensure the consistency of product quality.

[0012] 3. Installing infrared detectors at the assembly station of the filter manufacturing equipment allows for precise determination of whether installation components are in place. By detecting infrared light reflection, obstruction, and signal interruption, the position of the components can be quickly identified, ensuring that they accurately reach their assembly positions. This provides a reliable foundation for subsequent assembly operations and improves assembly accuracy. It also ensures smooth production flow. When an installation component is detected as not being properly transferred, a signal is promptly transmitted to the control system, and the component is re-clamped and transferred. This avoids assembly errors or stoppages caused by component positioning issues, reduces the time cost of manual troubleshooting and adjustments, improves overall production efficiency, and guarantees the efficient and stable operation of the filter manufacturing process.

[0013] 4. The mesh frame secures the mesh fabric by pressing the inner and outer walls together at the opening, creating a tight bond between the mesh and the frame. This effectively prevents the mesh from detaching from the frame during filter use, ensuring the overall stability of the filter structure and extending its lifespan. Whether subjected to the impact of water or airflow during normal filtration or external forces during installation and disassembly, the mesh remains firmly attached to the frame, ensuring the filter continues to perform its filtration function. When the diameter of the filter frame is less than 0.9 times the depth of the mesh, the mesh is difficult to install, the filtration area is reduced, and the fluid resistance increases. When the diameter of the filter frame is greater than 0.95 times the depth of the mesh, the diameter is too large, and the mesh cannot be fully tensioned within the frame, resulting in slackness and poor structural stability. Furthermore, when fluid passes through the filter, it tends to pass quickly through the wrinkles or slack areas of the mesh rather than evenly across the entire mesh, thus reducing overall filtration efficiency. Therefore, the optimal diameter of the filter frame is 0.9-0.95 times the depth of the mesh. This suitable diameter-to-depth ratio allows the mesh to fully expand within the frame, increasing the filtration area and ensuring more even fluid distribution as it passes through the filter, reducing the possibility of localized clogging and further improving the filter's filtration efficiency.

[0016] For ease of explanation, spatial relative terms such as “up,” “down,” “left,” and “right” are used in the embodiments to describe the relationship of one element or feature shown in the figures relative to another element or feature. It should be understood that, in addition to the orientations shown in the figures, spatial terms are intended to include different orientations of the device in use or operation. For example, if the device in the figures is inverted, an element described as being “down” of other elements or features would be positioned “up” of those other elements or features. Therefore, the exemplary term “down” can encompass both up and down orientations. The device may be positioned in other ways (rotated 90 degrees or in other orientations), and the spatial relative descriptions used herein will be interpreted accordingly.

[0018] Figures 1 to 2 The production process of a filter screen manufacturing equipment shown includes the following specific operation steps: S1, Raw material preparation: Place the filter screen raw material on the tray support of the feeding and conveying mechanism, adjust the tension adjustment component so that the filter screen raw material maintains the preset tension during the conveying process and can be output smoothly and continuously to the cutting mechanism; S2, Mesh Fabric 2 Cutting and Forming: The drive device drives the upper mold to move vertically downwards and precisely fits with the lower mold fixed on the worktable. Using the matching forming surfaces of the upper and lower molds, the filter screen is cut to the preset diameter size in one go. During the cutting process, the guide rod precisely restricts the movement direction of the cutting mold, and the formed mesh fabric 2 is pressed against the first equidistant rotating frame. At the same time, it is rotated to the trimming station. After being trimmed by the edge trimming gun, it is located in the second rotating bracket and rotated again to the assembly station. Then, the sliding seat carries the feeding and transporting mechanism to move back and forth along the length direction, entering the cutting cycle, forming an equidistant and swaying cutting effect. S3, Forming and Manufacturing of Space Frame 1: The annular workpiece is placed into the feeding cylinder and enters the annular stretching die holder in an orderly manner through the transport track. The transmission component of the stretching and shaping mechanism is activated. The second cylinder drives the sliding platform to move along the width direction of the guide rail, and the first cylinder drives the horizontal moving platform to move along the length direction of the guide rail. The linkage gripper assembly is precisely moved above the annular stretching die holder and is in a standby state. The stamping gun in the annular stretching die holder is activated to precisely extrude and shape the annular workpiece, completing one shaping operation. S4. Secondary cutting and shaping of space frame 1: The pneumatic clamp of the linkage gripper assembly precisely clamps the space frame 1 and transfers it to the bottom of the punching gun. The formed space frame 1 is then subjected to secondary cutting and shaping. The cut space frame 1 is then smoothly transferred to the next assembly station by the pneumatic clamp again. S5. Assembly and Forming: The mesh fabric 2 delivered to the assembly station is precisely aligned with the mesh frame 1 that has been transferred to the position. The assembly top rod is raised to perform preliminary positioning of the mesh fabric 2 and the mesh frame 1. The pressing component is started, and the drive motor drives the pressing mold base to move vertically downward. The pressing table is used to uniformly press the connection between the mesh fabric 2 and the mesh frame 1 to complete the overall riveting and forming of the filter screen.

[0019] In the raw material preparation stage, by placing the filter screen material on the tray support of the feeding and conveying mechanism and adjusting the tension adjustment component, the filter screen material can maintain the preset tension during the conveying process, ensuring the integrity and uniformity of the mesh during the cutting process and reducing the defect rate caused by unstable material conveying. The drive device drives the upper and lower dies to fit precisely, cutting the mesh sheet diameter in one go. The first equidistant rotating support ensures cutting accuracy, and automated transfer and cyclic operation improve production efficiency. The annular workpiece enters the annular stamping die seat via the transport track. The stretching and shaping mechanism is precisely positioned, and the stamping gun is precisely shaped to ensure that the mesh frame specifications meet the requirements. The air clamp precisely transfers the mesh frame 1 for secondary cutting and shaping, eliminating the deviation of the first forming and improving the overall quality of the mesh frame 1. The mesh 2 is precisely aligned with the mesh frame 1, the top rod is installed for positioning, and the clamping component is evenly clamped, enhancing the strength and stability of the filter screen structure and extending its service life. The sliding seat carries the feeding and conveying mechanism to reciprocate along the length direction, entering the cutting cycle, forming an equidistant and swaying cutting effect, realizing full utilization of raw materials and saving costs.

[0020] The first and second equidistant rotating brackets in S2 are controlled to rotate by the first and second motors, respectively. Rotation scales are provided on the outer rotating shafts of the first and second motors, and a matching positioning detector is provided on one side of each rotation scale to detect whether the rotation is in place. The specific steps are as follows: S21. When the first motor and the second motor drive the first equidistant rotating bracket and the second equidistant rotating bracket to rotate respectively, the positioning detector will continuously monitor the rotation scale and accurately identify the position change of the rotation scale. Once the rotating shaft fails to rotate to the preset scale position, the positioning detector will immediately capture this information and respond quickly. It will send a specific signal to the entire control system to stop the machine operation and correct the rotating bracket.

[0021] In the stamping and forming stage of the filter manufacturing equipment, the first and second equidistant rotating supports are controlled by the first and second motors, respectively. The rotating shaft on the outside of the motor is equipped with a rotation scale and a positioning detector. The positioning detector continuously monitors the rotation scale and accurately identifies position changes, which can ensure that the rotating frame rotates to the preset precise position, improve the transfer accuracy of the mesh fabric 2, and thus improve the production precision and quality of the filter. Once the rotating shaft fails to reach the preset scale, the detector can promptly provide feedback, stop the machine operation and correct the rotating frame, enhance production stability, reduce failures and losses, improve production efficiency, reduce labor costs, reduce human interference, and ensure the consistency of product quality.

[0022] The assembly station in S4 is also equipped with an infrared detector for detecting objects, and the specific operation is as follows: S41. When an installation accessory enters the detection range, the infrared light will be reflected or blocked, and the signal will be interrupted, indicating that the installation accessory is in place and waiting for the next instruction; if the infrared light signal is not interrupted, it means that the installation accessory has not been transmitted to the correct position, and the signal will be transmitted to the control system, and the installation accessory needs to be picked up and transmitted again.

[0023] Infrared detectors installed at the assembly station of filter manufacturing equipment can accurately determine whether the installation parts are in place. By detecting infrared light reflection, obstruction, and signal interruption, the position of the installation parts can be quickly identified, ensuring that the parts are accurately positioned for assembly. This provides a reliable basis for subsequent assembly operations and improves assembly accuracy. It also ensures the smoothness of the production process. When an installation part is detected as not being properly transferred, a signal is promptly transmitted to the control system, and the part is re-clamped and transferred, avoiding assembly errors or stoppages caused by part positioning issues. This reduces the time cost of manual troubleshooting and adjustments, improves overall production efficiency, and ensures the efficient and stable operation of the filter manufacturing process.

[0024] This application also provides a filter screen manufactured according to the production process of a filter screen manufacturing equipment, including an annular mesh frame 1 and a mesh fabric 2 pressed and fixed to the open end of the annular mesh frame 1. The mesh frame 1 has an inner wall and an outer wall. The mesh fabric 2 is fixedly connected to the mesh frame 1 by the mutual pressing of the inner wall and the outer wall at the opening. This pressing and fixing method makes the mesh fabric 2 and the mesh frame 1 form a tight bond. During the use of the filter screen, it can effectively prevent the mesh fabric 2 from falling off the mesh frame 1, ensuring the stability of the overall structure of the filter screen and extending the service life of the filter screen. Whether it is subjected to the impact of water flow or air flow during normal filtration operation, or subjected to external forces during installation and disassembly, the mesh fabric 2 can be firmly attached to the mesh frame 1, ensuring that the filter screen continues to perform its filtration function.

[0025] When the diameter of the mesh frame 1 is less than 0.9 times the depth of the mesh 2, the mesh 2 is difficult to install, the filtration area is reduced, and the fluid resistance increases. When the diameter of the mesh frame 1 is greater than 0.95 times the depth of the mesh 2, the diameter of the mesh frame 1 is too large, and the mesh 2 cannot be fully tensioned within the mesh frame 1, resulting in slackness and poor structural stability. Furthermore, when the fluid passes through the filter, it tends to pass quickly through the wrinkles or slack areas of the mesh 2 instead of passing evenly through the entire mesh 2, thus reducing the overall filtration efficiency. Therefore, the optimal diameter of the mesh frame 1 is 0.9-0.95 times the depth of the mesh 2. A suitable diameter-to-depth ratio allows the mesh 2 to fully expand within the mesh frame 1, increasing the filtration area and ensuring a more uniform distribution of fluid as it passes through the filter, reducing the possibility of localized blockage and further improving the filtration efficiency. The above description is merely a preferred embodiment of the present invention and is not intended to limit the invention. Ordinary variations and substitutions made by those skilled in the art within the scope of the present invention should be included within the protection scope of the present invention.
