According to the cross-sectional shape of the filter bags, there are cylindrical filter bags, rectangular filter bags, trapezoidal filter bags, and irregularly shaped filter bags. Among them, in the process of processing cylindrical filter bags, a cutting device is required to cut the filter bag cloth.

[0003] A Chinese patent with authorization announcement number CN 216838707 U discloses a bottom cutting device for filter bag processing, including a fixed platform. A hydraulic cylinder is fixedly installed in the inner cavity of the fixed platform, and the output end of the hydraulic cylinder penetrates through the surface of the fixed platform. An operating frame is rotatably connected to the outer wall of the hydraulic cylinder. An assembly groove is opened at the bottom of the operating frame, and a cutting tool is engaged in the assembly groove. A engaging mechanism penetrating into the assembly groove is fixedly installed in the inner cavity of the side wall of the operating frame. A processing base is fixedly installed on the surface of the fixed platform. During operation, the output end of the hydraulic cylinder drives the operating frame to move downward, causing the cutting tool to cut the fabric placed on the surface of the processing base. This enables batch cutting of fabric, eliminating the need for traditional manual cutting and improving processing efficiency.

[0004] Existing cutting devices are prone to cutting errors caused by filter bag misalignment during the cutting process. Since the cutting line of the filter bag cannot be easily corrected, the device's correction effect is poor, affecting the cutting accuracy.

Detailed Implementation

[0013] 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 scope of protection of the present utility model.

[0014] Please see Figure 1-4As shown, a cutting device for filter bag processing includes a worktable 1, a support frame mounted on the bottom side of the worktable 1, a PLC controller 2 mounted on the worktable 1, a correction assembly mounted on the worktable 1, a positioning assembly mounted on the correction assembly, and a support frame 3 mounted on the correction assembly. A camera 301 is mounted on the support frame 3. A first guide plate 302 is mounted on the worktable 1 via a mounting bracket. A first moving groove 303 is formed within the first guide plate 302. A first stepper motor 304 is mounted on the side wall of the first guide plate 302 via a base. A first lead screw 305 is mounted on the output shaft of the first stepper motor 304. The first lead screw 305 is rotatably mounted on the inner wall of the first moving groove 303, and a [missing information - likely a component or component] is assembled within the first moving groove 303. The first movable block 306 and the first lead screw 305 are surrounded by two first nylon telescopic sleeves. The first nylon telescopic sleeves are installed on the side wall of the first movable block 306 and the inner wall of the first movable groove 303. A positioning assembly is installed on the first movable block 306. The positioning assembly includes a movable frame 4, which is fixedly connected to the first movable block 306. An electric cylinder 401 is installed on the movable frame 4. A lifting frame 402 is installed on the rod of the electric cylinder 401. The lifting frame 402 is slidably connected to the movable frame 4. A connecting rod 403 is rotatably installed on the lifting frame 402 via a rotating shaft. A positioning plate 404 is rotatably installed on the other end of the connecting rod 403 via a rotating shaft. Two first limit blocks 405 and two second limit blocks 406 are symmetrically installed on the lifting frame 402. A connecting block 407 is installed on 402, and two return springs 408 are installed on the connecting block 407. The other end of the return spring 408 is fixedly connected to the connecting rod 403. During operation, the existing cutting device is prone to cutting errors caused by the filter bag cloth 603 deviating during the cutting process. Because it is not easy to correct the cutting line of the filter bag cloth 603, the device's correction effect is poor, affecting the cutting accuracy. Before cutting, the filter bag cloth 603 is marked with ink to mark the cutting line. After cutting, the sides and bottom of the filter bag cloth 603 are sewn together to form a cylindrical filter bag. Therefore, the filter bag cloth 603 has a square structure and is marked with cutting lines. When cutting the filter bag cloth 603, the cutting line is marked with ink to mark the cutting line. The filter bag 603 is released by the releasing assembly and then conveyed to the cutting position, which is the cutting slot 5. The camera 301 is model acA2000-50gm. The camera 301 captures and monitors the filter bag 603 in real time with high definition and sends a signal to the PLC controller 2. The PLC controller 2 uses image processing and machine learning algorithms to determine the accurate position of the filter bag 603. When the camera 301 captures that the cutting line of the filter bag 603 is located at the cutting position, the PLC controller 2 will send a command to the power switch of the second motor 601 in the releasing assembly to cut off the drive power of the second motor 601. The releasing assembly stops releasing the filter bag 603. At this time, the cutting line of the filter bag 603 is located at the cutting position. The positioning assembly then presses the filter bag 603 to prevent it from shifting. This is achieved by the operation of the electric cylinder 401, whose lever moves the lifting frame 402 vertically downwards. When the two connecting rods 403 on the lifting frame 402 are suspended, they are pulled by the two return springs 408 and contact the two second limit blocks 406. The two connecting rods 403 form an "eight" shape. As the lifting frame 402 moves vertically downwards, it moves the two connecting rods 403 downwards, which in turn move the two positioning blocks 406. The plate 404 moves downward. When the two positioning plates 404 come into contact with the filter bag cloth 603, the lifting frame 402 continues to move downward. The two connecting rods 403 will rotate outward until they come into contact with the two first limit blocks 405. The two first limit blocks 405 limit the two connecting rods 403. During the outward rotation of the two connecting rods 403, the two positioning plates 404 will move synchronously and in opposite directions on the filter bag cloth 603 to flatten the filter bag cloth 603. Finally, they are pressed and fixed, thus achieving the pressing of the filter bag cloth 603. After the filter bag cloth 603 is pressed and positioned, the cutting line of the filter bag cloth 603 may deviate from the cutting position. Since the camera 301 performs high-definition image capture and real-time monitoring of the filter bag cloth 603, when the camera 301 detects that the cutting line of the filter bag cloth 603 has deviated from the cutting position, the PLC controller 2 controls the operation of the correction component. Specifically, the first stepper motor 304 operates, driving the first lead screw 305 to rotate. The first lead screw 305 drives the first moving block 306 on it to move horizontally. The first moving block 306 drives the moving frame 4 to move horizontally. The moving frame 4 drives the entire positioning component to move horizontally. The positioning component drives the pressed filter bag cloth 603 to move horizontally. Because the two positioning plates 404 and the filter bag cloth 603... The friction between the two positioning plates 3 is greater than the friction between the filter bag cloth 603 and the worktable 1. Therefore, the two positioning plates 404 can drive the filter bag cloth 603 to move horizontally. The filter bag cloth 603 moves slightly horizontally at the cutting position, which drives the cutting line on it to move slightly horizontally. When the cutting line is aligned with the cutting groove 5 of the cutting position, the PLC controller 2 will send a command to the power switch of the first stepper motor 304 to cut off the drive power of the first stepper motor 304. The correction component stops moving the filter bag cloth 603 horizontally. At this time, the cutting line of the filter bag cloth 603 is accurately aligned with the cutting groove 5. This structure can easily correct the cutting line of the filter bag cloth 603, which is conducive to improving the correction effect of the device and improving the cutting accuracy.

[0015] Please see Figure 5As shown, a cutting assembly is installed on the workbench 1. The cutting assembly includes a cutting groove 5. The workbench 1 has a cutting groove 5. A second guide plate 501 is installed on the bottom side of the workbench 1. A second moving groove 502 is opened inside the second guide plate 501. A second stepper motor 503 is installed on the side wall of the second guide plate 501 via a machine base. A second lead screw is installed on the output shaft of the second stepper motor 503. The second lead screw is rotatably installed on the inner wall of the second moving groove 502. A second moving block 504 is assembled inside the second moving groove 502. Two second nylon telescopic sleeves 505 are installed around the second lead screw. The second nylon telescopic sleeves 505 are installed on the second moving block. On the side wall of 504 and the inner wall of the second moving groove 502, a knife holder 506 is fixedly installed on the second moving block 504, and a circular knife 507 is rotatably installed on the knife holder 506. A first motor 508 is installed on the knife holder 506 via a machine base. The output shaft of the first motor 508 is fixedly connected to the rotating shaft of the circular knife 507. A loosening assembly is placed on one side of the worktable 1. The loosening assembly includes a fixing frame 6. A second motor 601 is installed on the fixing frame 6 via a machine base. A loosening roller 602 is installed on the output shaft of the second motor 601. Filter bag cloth 603 is wound on the loosening roller 602. Cutting lines are marked on the filter bag cloth 603. The worktable 1 is rotatably connected to a wheel frame. Guide wheel 604; During operation, the existing cutting device has difficulty connecting the filter bag cloth 603 during the cutting process, resulting in poor cutting efficiency. Through the operation of the release component, that is, the operation of the second motor 601, the release roller 602 is driven to rotate, and the release roller 602 drives the filter bag cloth 603 to rotate, releasing the filter bag cloth 603. After that, the released filter bag cloth 603 moves horizontally on the worktable 1 via the guide wheel 604 until the cutting line of the filter bag cloth 603 is in the cutting position. Then, the positioning component presses the filter bag cloth 603, and the correction component corrects the cutting line of the filter bag cloth 603. At this time, the filter bag cloth The cutting line of filter bag 603 is accurately aligned with the cutting groove 5. Then, the cutting assembly cuts the filter bag cloth 603 at the cutting line. That is, the first motor 508 operates, driving the circular knife 507 to rotate at high speed. At the same time, the second stepper motor 503 operates, driving the second lead screw to rotate. The second lead screw drives the second moving block 504 on it to move horizontally. The second moving block 504 drives the knife holder 506 to move horizontally. The knife holder 506 drives the high-speed rotating circular knife 507 to move horizontally. The circular knife 507 cuts the filter bag cloth 603 at the cutting line, realizing the rapid cutting of the filter bag cloth 603. After the cutting is completed, the circular knife 507 moves horizontally in the opposite direction and returns to its original position.By setting a first nylon telescopic sleeve and a second nylon telescopic sleeve 505 around the first lead screw 305 and the second lead screw, the first nylon telescopic sleeve and the second nylon telescopic sleeve 505 can protect the first lead screw 305 and the second lead screw, preventing the fibers generated during the cutting of the filter bag cloth 603 from affecting the first lead screw 305 and the second lead screw. Then, the above steps are repeated to cut the next piece of filter bag cloth 603, realizing the connected cutting of the filter bag cloth 603, which helps to improve the efficiency of cutting.

[0016] Working principle: Existing cutting devices are prone to cutting errors caused by filter bag fabric 603 misalignment during the cutting process. Because the cutting lines of the filter bag fabric 603 cannot be easily corrected, the device's correction effect is poor, affecting cutting accuracy. Before cutting, the filter bag fabric 603 has cutting lines marked with ink. After cutting, the sides and bottom of the filter bag fabric 603 are sewn together to form a cylindrical filter bag. Therefore, the filter bag fabric 603 has a square structure and is marked with cutting lines. During the cutting of the filter bag fabric 603, the filter bag fabric is... The filter bag 603 is released by the releasing assembly and then conveyed to the cutting position, which is located at cutting slot 5. Camera 301 (model ACA2000-50GM) captures high-definition images of the filter bag 603 in real time and sends signals to PLC controller 2. PLC controller 2 uses image processing and machine learning algorithms to determine the precise position of the filter bag 603. When camera 301 detects that the cutting line of the filter bag 603 is at the cutting position, PLC controller 2 sends a command to the power switch of the second motor 601 within the releasing assembly to cut the filter bag. The drive power of the second motor 601 is disconnected, and the loosening assembly stops loosening the filter bag cloth 603. At this time, the cutting line of the filter bag cloth 603 is located at the cutting position. Then, the positioning assembly presses the filter bag cloth 603 to prevent it from shifting. The electric cylinder 401 operates, and its lever drives the lifting frame 402 to move vertically downward. When the two connecting rods 403 on the lifting frame 402 are suspended, they are in contact with the two second limit blocks 406 due to the traction of the two return springs 408. The two connecting rods 403 have an "eight" structure. As the lifting frame 402 moves vertically downward, it drives the... The two connecting rods 403 move downwards, which in turn drive the two positioning plates 404 to move downwards. When the two positioning plates 404 come into contact with the filter bag cloth 603, the lifting frame 402 continues to move downwards, and the two connecting rods 403 will rotate outwards until they come into contact with the two first limit blocks 405. The two first limit blocks 405 limit the two connecting rods 403, while the two positioning plates 404 move synchronously and in opposite directions on the filter bag cloth 603 during the outward rotation of the two connecting rods 403, flattening the filter bag cloth 603 and finally pressing it to fix it, thus achieving the pressing of the filter bag cloth 603.After the filter bag cloth 603 is pressed and positioned, the cutting line of the filter bag cloth 603 may deviate from the cutting position. Because the camera 301 performs high-definition image capture and real-time monitoring of the filter bag cloth 603, when the camera 301 detects that the cutting line of the filter bag cloth 603 has deviated from the cutting position, the PLC controller 2 controls the operation of the correction component. Specifically, the first stepper motor 304 operates, driving the first lead screw 305 to rotate. The first lead screw 305 drives the first moving block 306 on it to move horizontally. The first moving block 306 drives the moving frame 4 to move horizontally. The moving frame 4 drives the entire positioning component to move horizontally. The positioning component then drives the pressed filter bag cloth 603 to move horizontally. Because the two... The friction between the positioning plate 404 and the filter bag 603 is greater than the friction between the filter bag 603 and the worktable 1. Therefore, the two positioning plates 404 can drive the filter bag 603 to move horizontally. The filter bag 603 moves slightly horizontally at the cutting position, causing the cutting line on it to move slightly horizontally. When the cutting line is aligned with the cutting groove 5 at the cutting position, the PLC controller 2 will send a command to the power switch of the first stepper motor 304 to cut off the drive power of the first stepper motor 304. The correction component stops moving the filter bag 603 horizontally. At this time, the cutting line of the filter bag 603 is accurately aligned with the cutting groove 5. This structure can easily correct the cutting line of the filter bag 603. This improves the device's correction effect and cutting accuracy. Existing cutting devices struggle to connect and cut the filter bag fabric 603, resulting in low efficiency. The new method addresses this by using a release assembly (second motor 601) to rotate the release roller 602, which in turn rotates the filter bag fabric 603, releasing it. The released filter bag fabric 603 then moves horizontally on the worktable 1 via guide wheels 604 until the cutting line is positioned. The positioning assembly then presses the filter bag fabric 603 firmly, and the correction assembly adjusts the cutting line. Correction is then performed. At this point, the cutting line of the filter bag cloth 603 is accurately aligned with the cutting groove 5. Then, the cutting assembly cuts the filter bag cloth 603 at the cutting line. Specifically, the first motor 508 operates, driving the circular knife 507 to rotate at high speed. At the same time, the second stepper motor 503 operates, driving the second lead screw to rotate. The second lead screw drives the second moving block 504 on it to move horizontally. The second moving block 504 drives the knife holder 506 to move horizontally. The knife holder 506 drives the high-speed rotating circular knife 507 to move horizontally. The circular knife 507 cuts the filter bag cloth 603 at the cutting line, realizing the rapid cutting of the filter bag cloth 603. After the cutting is completed, the circular knife 507 moves horizontally in the opposite direction and returns to its original position.By setting a first nylon telescopic sleeve and a second nylon telescopic sleeve 505 around the first lead screw 305 and the second lead screw, the first nylon telescopic sleeve and the second nylon telescopic sleeve 505 can protect the first lead screw 305 and the second lead screw, preventing the fibers generated during the cutting of the filter bag cloth 603 from affecting the first lead screw 305 and the second lead screw. Then, the above steps are repeated to cut the next piece of filter bag cloth 603, realizing the connected cutting of the filter bag cloth 603, which helps to improve the efficiency of cutting.
