Description

Technical Field

[0001] This utility model relates to the field of cutting device technology, specifically a filter element cutting device. Background Technology

[0002] In the field of industrial filtration, filter elements are core components, and their production precision and efficiency directly affect the performance and cost of end products. In the traditional filter element production process, the counting of folds and cutting rely on manual operation, which exposes significant drawbacks such as low efficiency, insufficient precision, and high safety risks.

[0003] For example, the national authorized patent announcement number CN212601995U discloses an automatic filter element cutting device, which relates to the field of automatic cutting technology. This utility model includes a base; a fixed plate is provided on one side of the base, and a motor is fixedly connected to the top of the fixed plate. A transmission disc is fixedly connected to the output end of the motor, and a flat thread is provided on one side of the transmission disc; a fixed box is provided on one side of the base, and a channel is opened inside the fixed box. Two sliding rods, a moving block, and a slider are slidably fitted inside the channel. This utility model improves the efficiency of the cutting device by installing a motor above the fixed plate, causing the motor to drive the transmission disc to rotate, and the transmission disc to drive the moving block to move. This allows the two sliders to move towards the base along the channel. Springs are provided around the sliding rods to reduce impact force during the movement of the sliding rods, reducing wear on parts, thereby extending the service life of the device, enhancing the quality of the filter element, reducing the defect rate of the filter element, and improving the integrity of the filter element.

[0004] However, the aforementioned automatic filter cutting device cannot automatically fold the filter cartridge according to its thickness to cut it at the corresponding position during the filter cartridge cutting process. It cannot dynamically correct the cutting position according to the actual thickness, which will result in the length and folding thickness of the cut filter cartridge not conforming to the design standard. Especially when the thickness deviation is large, the phenomenon of "more folding and less cutting" or "less folding and more cutting" will occur, which will directly affect the filter cartridge filtration area and structural strength, resulting in unstable product performance.

[0005] Ensure that the number of folds in each filter element is consistent, meeting the design requirements for filtration area and structural strength. Utility Model Content

[0006] The purpose of this invention is to provide a filter element cutting device to solve the problem mentioned in the background art that the filter element cannot be automatically folded according to its thickness to cut it at the corresponding position during the filter element cutting process.

[0007] To achieve the above objectives, this utility model provides the following technical solution:

[0008] A filter cartridge cutting device includes: a U-shaped frame, a conveyor mounted inside the U-shaped frame, a folding cover rotatably mounted at the other end of the U-shaped frame, a folding pressing mechanism fixedly mounted inside the U-shaped frame, the pressing end of the folding pressing mechanism being able to flip and press against both ends between the conveyor and the folding cover to achieve pressing of the conveyed filter cartridge, and an n-shaped frame fixedly mounted on the upper surface of the U-shaped frame, a laser ranging sensor fixedly mounted inside the n-shaped frame.

[0009] Preferably, the signal transmitting end of the laser rangefinder is connected to the signal receiving end of the controller, while the control output end of the controller is electrically connected to the electrical control end of the conveyor and the folding pressing mechanism. The models of the laser rangefinder and the controller are VL53L0X and STM32F103C8T6, respectively.

[0010] Preferably, the lower surface of the folding cover is rotatably connected to the piston rod of the first electric push rod, and the other end of the first electric push rod is rotatably mounted on the upper surface inside the U-shaped frame. The first electric push rod is also controlled by the controller.

[0011] Preferably, a linear module is fixedly installed on the lower surface of the folding cover, and the moving block of the linear module slides through to the upper surface of the folding cover, and a cutter is fixedly installed on the upper surface.

[0012] Preferably, the folding pressing mechanism includes a U-shaped plate, with two sets of sliders slidably installed at both ends of the U-shaped plate. A second electric push rod is fixedly installed on the upper surface of each pair of sliders. A Y-shaped frame is fixedly installed at one end of the piston rod of the second electric push rod. A gear is rotatably installed between the Y-shaped frames, and a pressing rod is fixedly installed at one end of the outer surface of the gear.

[0013] Preferably, an L-shaped rod is fixedly installed at one end of the slider on one side of the second electric push rod, and a U-shaped sliding plate is fixedly installed on the upper surface of the L-shaped rod. The U-shaped sliding plate slides through both ends of the U-shaped frame, and a rack is fixedly installed inside the U-shaped sliding plate. The rack meshes with a gear, so that the gear can be pulled by the second electric push rod to roll inside the U-shaped sliding plate by meshing with the rack.

[0014] Preferably, a dual-axis motor is fixedly installed at the center of the upper surface of the U-shaped plate. One end of each output shaft of the dual-axis motor is fixedly installed with a threaded rod. The threaded rods are threaded through the sliders at both ends of the inner side of the two sets of second electric push rods, and the threaded rods fixedly installed at both ends of the dual-axis motor are designed to be opposite each other, so that it can slide synchronously inward or outward through the transmission of the two sets of second electric push rods.

[0015] Preferably, both the second electric actuator and the dual-axis motor are controlled by a controller.

[0016] Compared with the prior art, the beneficial effects of this utility model are:

[0017] 1. Through the design of a conveyor, laser rangefinder, folding cover, first electric push rod, linear module, cutter, and folding position pressing mechanism, during the filter element cutting process, a filter element of a specific size is placed on the surface of the conveyor. The filter element is conveyed forward with the conveyor. When it reaches the position between the conveyor and the folding cover, the laser rangefinder immediately detects the filter element and sends a signal to the controller. The controller then controls the conveyor to continue conveying the filter element for a precisely set length and then stop. At this point, half of the filter element is on the upper surface of the folding cover. This precise position control ensures the accuracy of the reference for subsequent folding and cutting processes, reduces manual intervention, and improves positioning accuracy. Subsequently, the controller controls the folding position pressing mechanism to flip and press against both ends of the upper surface in the middle of the filter element, providing stable pressing force for the filter element folding, preventing the filter element from shifting during folding, and ensuring folding quality. Next, the controller drives the first electric push rod to push the folding cover to flip, causing the filter element to fold along the center of the folding position pressing mechanism. This mechanically linked folding method can achieve standardized folding actions and ensure the consistency of each fold. After folding, the first electric push rod pulls the folding cover back to a horizontal position, and the folded filter element... The filter element can then be positioned on the conveyor surface and simultaneously within the detection range of the laser rangefinder sensor, allowing it to detect the filter element thickness in real time and feed the data back to the controller, forming a closed-loop control system. If the filter element thickness is detected as not meeting the set standard, the controller first activates the folding and pressing mechanism to pull the pressing end out of the filter element, and then repeats the above conveying, pressing, and folding steps until the filter element thickness meets the standard. This automated thickness detection and iterative folding mechanism can accurately control the filter element thickness, significantly improving the quality stability of the filter element and reducing the defect rate. When the filter element thickness reaches the standard, the controller controls the linear module to drive the cutter fixedly installed on the upper surface of the moving block to slide on the surface of the folded cover to the preset cutting position. Then, the first electric push rod is activated again to push the folded cover, driving the cutter to cut the filter element. The precise motion control of the linear module enables the cutter to quickly and accurately reach the cutting position, improving cutting efficiency and accuracy. The entire process realizes fully automated operation from conveying, folding, detection to cutting, reducing manual intervention, improving production efficiency, and reducing labor costs. At the same time, the closed-loop thickness detection and control system ensures the stability and consistency of filter element quality, improving the overall quality of the product.

[0018] 2. Through the design of a dual-axis motor, Y-shaped frame, gears, pressing rod, U-shaped slide plate, second electric push rod, threaded rod, and rack, after the center of the filter element is conveyed between the conveyor and the folding cover, the controller can activate the second electric push rod to pull the Y-shaped frame fixed at one end of the piston rod. The Y-shaped frame then drives the internally rotating gear to roll within the U-shaped slide plate through meshing with the rack. This causes the gear to rotate and press the pressing rod, which is fixed on the outer surface, onto both ends of the upper surface of the filter element. This pressing method, driven by gear and rack meshing, provides stable and uniform pressing force, effectively preventing the filter element from shifting during folding and greatly ensuring the reliability of the folding quality. After the filter element is folded, the pressing rod needs to be removed from the... When the folded filter element is pulled out, the dual-axis motor drives the threaded rods at both ends to drive the threaded slider, which in turn pushes the second electric push rod through the slider and slides outward synchronously within the U-shaped plate. The pushed second electric push rod then drives the Y-shaped frame and L-shaped rod to slide outward. The pushed Y-shaped frame and L-shaped rod then drive the pressing rod and the U-shaped slide plate to be pulled out from the U-shaped frame and the filter element, respectively. The entire extraction process is synchronized through the precise cooperation of the dual-axis motor and the threaded rod, ensuring the coordination and stability of the action. This not only avoids damage to the structure of the folded filter element but also allows for quick resetting, preparing the filter element for the folding cover to fold again. This significantly improves the continuity and efficiency of the production process, reduces downtime, and ensures the smooth operation of the production line. Attached Figure Description

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] like Figure 1 As shown, this embodiment provides a filter element cutting device, including: a U-shaped frame 1, a conveyor 101 is installed inside the U-shaped frame 1, a folding cover 104 is rotatably installed at the other end inside the U-shaped frame 1, a folding position pressing mechanism 2 is fixedly installed inside the U-shaped frame 1, the pressing end of the folding position pressing mechanism 2 can flip and press between the two ends between the conveyor 101 and the folding cover 104 to realize the pressing of the conveyed filter element, an n-shaped frame 102 is fixedly installed on the upper surface of the U-shaped frame 1, and a laser range sensor 103 is fixedly installed inside the n-shaped frame 102.

[0025] The signal transmitting end of the laser rangefinder 103 is connected to the signal receiving end of the controller, while the control output end of the controller is electrically connected to the electrical control end of the conveyor 101 and the folding and pressing mechanism 2. The models of the laser rangefinder 103 and the controller are VL53L0X and STM32F103C8T6, respectively.

[0026] The lower surface of the folding cover 104 is rotatably connected to the piston rod of the first electric push rod 105. The other end of the first electric push rod 105 is rotatably mounted on the upper surface inside the U-shaped frame 1. The first electric push rod 105 is also controlled by the controller.

[0027] A linear module 106 is fixedly installed on the lower surface of the folding cover 104. The moving block of the linear module 106 slides through to the upper surface of the folding cover 104, and a cutter 107 is fixedly installed on the upper surface.

[0028] Through the design of the conveyor 101, laser rangefinder 103, folding cover 104, first electric push rod 105, linear module 106, cutter 107, and folding position pressing mechanism 2, during the filter element cutting process, by placing a filter element of a specific size on the surface of the conveyor 101, the filter element is conveyed forward with the conveyor 101. When it reaches the position between the conveyor 101 and the folding cover 104, the laser rangefinder 103 immediately detects the filter element and sends a signal to the controller. The controller can then control the conveyor 101 to continue conveying the filter element for a precisely set length and then stop. At this time, half of the filter element is on the upper surface of the folding cover 104. This precise positioning... The control system ensures the accuracy of subsequent folding and cutting processes, reduces manual intervention, and improves positioning precision. Subsequently, the controller controls the folding pressing mechanism 2 to flip and press against both ends of the upper surface in the middle of the filter element, providing stable pressing force for folding and preventing displacement of the filter element during folding, thus ensuring folding quality. Next, the controller drives the first electric push rod 105 to push the folding cover 104 to flip, causing the filter element to fold along the center of the folding pressing mechanism 2. This mechanically linked folding method enables standardized folding actions, ensuring consistency in each fold. After folding, the first electric push rod 105 pulls the folding cover 104 back to its original position. The filter element is flat, and after folding, it can be placed back on the surface of conveyor 101 and simultaneously within the detection range of laser range sensor 103. This allows the laser range sensor to detect the filter element thickness in real time and feed the data back to the controller, forming a closed-loop control system. If the filter element thickness is detected to be below the set standard, the controller first activates the folding pressing mechanism 2 to pull the pressing end out of the filter element, and then repeats the above conveying, pressing, and folding steps until the filter element thickness meets the standard. This automated thickness detection and iterative folding mechanism can accurately control the filter element thickness, significantly improve the quality stability of the filter element, and reduce the defect rate. When the filter element thickness reaches the standard, the controller controls the linear module 106. The cutter 107, which is fixedly mounted on the upper surface of the moving block, slides on the surface of the folded cover 104 to the preset cutting position. Then, the first electric push rod 105 is activated again to push the folded cover 104, driving the cutter 107 to cut the filter element. The precise motion control of the linear module 106 enables the cutter 107 to reach the cutting position quickly and accurately, improving cutting efficiency and precision. The entire process realizes fully automated operation from conveying, folding, detection, and cutting, reducing manual intervention, improving production efficiency, and reducing labor costs. At the same time, the closed-loop thickness detection and control system ensures the stability and consistency of filter element quality, improving the overall quality of the product.

[0029] like Figures 2-3As shown, the folding pressing mechanism 2 includes a U-shaped plate 201. Two sets of sliders 210 are slidably installed at both ends of the U-shaped plate 201. A second electric push rod 208 is fixedly installed on the upper surface of each pair of sliders 210. A Y-shaped frame 203 is fixedly installed at one end of the piston rod of the second electric push rod 208. A gear 204 is rotatably installed between the Y-shaped frames 203. A pressing rod 205 is fixedly installed at one end of the outer surface of the gear 204.

[0030] An L-shaped rod 207 is fixedly installed at one end of the slider 210 on one side of the second electric push rod 208. A U-shaped slide plate 206 is fixedly installed on the upper surface of the L-shaped rod 207. The U-shaped slide plate 206 slides through both ends of the U-shaped frame 1. A rack 211 is fixedly installed inside the U-shaped slide plate 206. The rack 211 meshes with the gear 204, so that the gear 204 can be pulled by the second electric push rod 208 and roll inside the U-shaped slide plate 206 through meshing with the rack 211.

[0031] A dual-axis motor 202 is fixedly installed at the center of the upper surface of the U-shaped plate 201. A threaded rod 209 is fixedly installed at one end of each output shaft of the dual-axis motor 202. The threaded rod 209 is threaded through the sliders 210 at both ends of the inner side of the two sets of second electric push rods 208 respectively. The threaded rods 209 fixedly installed at both ends of the dual-axis motor 202 are designed to be opposite each other, so that it can slide synchronously inward or outward through the transmission of the two sets of second electric push rods 208.

[0032] The second electric actuator 208 and the dual-axis motor 202 are both controlled by the controller.

[0033] Through the design of a dual-axis motor 202, a Y-shaped frame 203, a gear 204, a pressing rod 205, a U-shaped sliding plate 206, a second electric push rod 208, a threaded rod 209, and a rack 211, after the center of the filter element is conveyed between the conveyor 101 and the folding cover 104, the controller can activate the second electric push rod 208 to pull the Y-shaped frame 203 fixedly installed at one end of the piston rod. The Y-shaped frame 203 then drives the internally rotating gear 204 to roll within the U-shaped sliding plate 206 through meshing with the rack 211. This allows the gear 204 to drive the pressing rod 205, which is fixedly installed on the outer surface, to flip and press it onto both ends of the upper surface of the middle of the filter element. This pressing method, driven by the meshing of the gear 204 and rack 211, provides a stable and uniform pressing force, effectively preventing the filter element from shifting during folding and greatly ensuring the reliability of the folding quality. After the filter element is folded, the pressing rod needs to be... When the control rod 205 is pulled out from the folded filter element, the dual-axis motor 202 can be activated to drive the threaded rods 209 at both ends and the threaded transmission slider 210 to push the second electric push rod 208 to slide outward synchronously within the U-shaped plate 201 through the slider 210. The pushed second electric push rod 208 can then drive the Y-shaped frame 203 and L-shaped rod 207 to slide outward. The pushed Y-shaped frame 203 and L-shaped rod 207 can then drive the pressing rod 205 and the U-shaped slide plate 206 to be pulled out from the U-shaped frame 1 and the filter element respectively. The entire extraction process is synchronized through the precise cooperation between the dual-axis motor 202 and the threaded rod 209, ensuring the coordination and stability of the action. This not only avoids damage to the structure of the folded filter element, but also allows for quick resetting, preparing for the folding cover 104 to fold the filter element again. This significantly improves the continuity and efficiency of the production process, reduces downtime, and ensures the smooth operation of the production line.

[0034] Based on the above technical solution, the working steps of this solution are summarized as follows: During the filter element cutting process, a filter element of a specific size is placed on the surface of the conveyor 101. The filter element is conveyed forward with the conveyor 101. When it reaches the position between the conveyor 101 and the folding cover 104, the laser range sensor 103 immediately detects the filter element and sends a signal to the controller. The controller then controls the conveyor 101 to continue conveying the filter element for a precisely set length and then stop. At this time, half of the filter element is on the upper surface of the folding cover 104. This precise position control ensures the accuracy of the reference for subsequent folding and cutting processes, reduces manual intervention, and improves positioning accuracy. Subsequently, the controller controls the second electric push rod 208. Pulling the piston rod activates the Y-shaped bracket 203, which is fixedly mounted at one end. This causes the internally rotating gear 204 to roll within the U-shaped slide plate 206, meshing with the rack 211. The gear 204 then causes the pressing rod 205, fixedly mounted on the outer surface, to flip and press against both ends of the upper surface of the filter element. Next, the controller drives the first electric push rod 105 to push the folding cover 104 to flip, folding the filter element along the center of the pressing rod 205. After folding, the first electric push rod 105 pulls the folding cover 104 back to a horizontal position. The folded filter element then rests on the surface of the conveyor 101 and is simultaneously within the detection range of the laser range sensor 103. Inside, the system monitors the filter element thickness in real time and feeds the data back to the controller, forming a closed-loop control system. If the filter element thickness is detected to be below the set standard, the controller first activates the dual-axis motor 202 to drive the threaded rods 209 at both ends and the threaded transmission slider 210 to push the second electric push rod 208. Through the slider 210, the second electric push rod 208 slides outward synchronously within the U-shaped plate 201. The pushed second electric push rod 208 then drives the Y-shaped frame 203 and L-shaped rod 207 to slide outward. The pushed Y-shaped frame 203 and L-shaped rod 207 then drive the pressing rod 205 and the U-shaped slide plate 206 to be pulled out from the U-shaped frame 1 and the filter element, respectively. Then, the second electric push rod 208 and the dual-axis motor 202 can be activated again to push the pressing rod 205 outward. 05. Flip and unfold, and pull the second electric push rod 208 back to its original position. Then, the controller controls the conveyor 101 to continue to transport half of the folded filter element to the upper surface of the folded cover 104. Then, the second electric push rod 208 can be started again to pull the Y-shaped frame 203 to drive the pressing rod 205 to press the filter element at both ends of the center part again and be flipped and folded by the folded cover 104 until the filter element thickness reaches the standard. When the filter element thickness reaches the standard, the controller controls the linear module 106 to drive the cutter 107 fixedly installed on the upper surface of the moving block to slide on the surface of the folded cover 104 to the preset cutting position. Then, the first electric push rod 105 is started again to push the folded cover 104 and drive the cutter 107 to cut the filter element.

[0035] In summary, this system enables fully automated operation of the entire process from conveying, folding, testing, and cutting, reducing manual intervention, improving production efficiency, and lowering labor costs. At the same time, the closed-loop thickness detection and control system ensures the stability and consistency of filter element quality, thereby improving the overall quality of the product.
