Description

[0002] The diaper core is the most important component of diapers. Its main function is to absorb and lock in liquids, keep the skin dry and prevent leakage. During the production and processing of diapers, the diaper core needs to be cut into suitable sizes according to the set dimensions using core cutting equipment.

[0004] However, in the prior art, before cutting the diaper core, it is necessary to first wrap it with a non-woven fabric, then use a flattening device to flatten it, then use a conveyor belt to feed it, and then use a cutting mechanism to cut the fed diaper core. Because the outside of the diaper core is wrapped with a non-woven fabric with a certain elasticity, the core has a certain elasticity as a whole when cutting. Due to the differences in the thickness of the cores of different batches and the tension applied to the non-woven fabric when wrapping, the overall elasticity of the diaper core is different. After cutting, the core will shrink to a certain extent. The core with high elasticity will shrink more, and the core with low elasticity will shrink less. The existing cutting equipment cannot adjust the cutting speed of the cutting tool during the core cutting process. Cutting different batches of cores at the same cutting speed will cause excessive size errors in the cut cores. Summary of the invention

[0033] Example 1: Reference Figure 1 - Fig. 9As shown, a diaper core cutting device includes a main mechanism 1, which includes a cutting frame 11, a feeding roller assembly 14 and a discharging roller assembly 15. The cutting frame 11 is fixedly connected to a cutting table 12 on the upper portion, and a cutting mechanism 2 is installed on the upper portion of the cutting frame 11. Limiting mechanisms 4 are respectively installed on both sides of the cutting mechanism 2, and the limiting mechanisms 4 are fixedly connected to the cutting frame 11. A monitoring mechanism 3 is arranged on one side of the cutting mechanism 2, and the monitoring mechanism 3 is installed between the discharging roller assembly 15 and the cutting mechanism 2, and the monitoring mechanism 3 is fixedly connected to the cutting frame 11.

[0034] The cutting mechanism 2 includes a No. 1 slide rail 21 and a No. 2 servo motor 29. The No. 1 slide rail 21 is fixedly installed on the cutting frame 11. The No. 1 slide rail 21 is vertically slidably connected to the inside thereof. The No. 1 slide rail 22 is rotatably connected to a cutting roller 25 on the side thereof.

[0036] The size monitoring system 6 is externally electrically connected to the cutting adjustment system 5, which includes a servo control system No. 1 51 and a servo control system No. 2 52. The servo control system No. 1 51 is electrically connected to the servo motor No. 2 29, and the servo control system No. 2 52 is electrically connected to the servo motor No. 3 43. The servo control system No. 1 51 adjusts the rotation speed of the servo motor No. 2 29 according to the control parameters output by the control parameter generation module 63, and the servo control system No. 2 52 controls the servo motor No. 3 43 according to the control parameters output by the control parameter generation module 63, thereby adjusting the position of the limit frame 47.

[0037] The main mechanism 1 includes a feed roller assembly 14 and a discharge roller assembly 15 . A waste recovery assembly 13 is installed below the cutting table 12 . The feed roller assembly 14 is rotatably connected to one end of the cutting frame 11 , and the discharge roller assembly 15 is rotatably connected to the other end of the cutting frame 11 .

[0038] The cutting mechanism 2 includes a No. 2 slide rail 27 fixedly mounted on the cutting frame 11, a No. 2 slider 28 is vertically slidably connected inside the No. 2 slide rail 27, a No. 2 servo motor 29 is mounted on one side of the No. 2 slider 28, and the output end of the No. 2 servo motor 29 passes through the No. 2 slider 28 and is fixedly connected to the end of the cutting roller 25.

[0039] The No. 1 slide rail 21 and the No. 2 slide rail 27 are respectively located on the cutting frame 11 at both ends of the cutting table 12. A No. 1 servo motor 23 is installed on the upper part of the No. 1 slide rail 21. The output end of the No. 1 servo motor 23 passes through the top of the No. 1 slide rail 21, and the output end of the No. 1 servo motor 23 is fixedly connected to a No. 1 adjusting screw rod 24. The No. 1 adjusting screw rod 24 is rotatably connected to the inside of the No. 1 slide rail 21, and the No. 1 adjusting screw rod 24 is threadedly connected to the No. 1 slider 22. A No. 1 fixing plate 210 is fixedly connected to the side of the No. 2 slide rail 27, and a No. 1 limiting rod 211 is fixedly connected to the bottom of the No. 1 fixing plate 210. A No. 1 limiting plate 212 is fixedly connected to the side of the No. 2 servo motor 29, and the No. 1 limiting rod 211 is plugged with the No. 1 limiting plate 212. A through groove is provided on the side of the No. 2 slide rail 27, and the end of the No. 2 servo motor 29 is located inside the through groove and fixedly connected to the No. 2 slider 28.

[0040] During the use of the present invention, the external feeding device passes the non-woven fabric wrapped and flattened diaper core through the middle of the feeding roller assembly 14, and then passes through the middle of the discharging roller assembly 15 to connect with the equipment of the next process. After the diaper core is loaded and connected, the cutting roller 25 and the cutter head 26 are driven by the second servo motor 29 to rotate, and the core is continuously cut by the cutter head 26. Before entering the next process, the cut core will pass under the high-speed camera 34. At this time, the high-speed camera 34 will capture the image of the cut diaper core, and at the same time, the image of the measurement reference target 38 is captured as the size monitoring system 6 to calculate the cutting size of the core reference, so as to accurately calculate the length of the core body after cutting. When it is detected that the length of the cut core body is too long, the control parameter generation module 63 calculates and generates the control parameter and transmits it to the No. 1 servo control system 51. The No. 1 servo control system 51 increases the rotation speed of the No. 2 servo motor 29, thereby increasing the cutting speed of the cutter head 26 on the moving core body, thereby reducing the length of the cut core body. When the length of the cut core body is too short, the rotation of the No. 2 servo motor 29 is reduced according to the above control logic, so that the size of the cut core body is lengthened, so that the core bodies of different batches can be accurately cut without stopping the machine for adjustment.

[0041] After the equipment has been running for a period of time, the cutter head 26 needs to be maintained or replaced. During the process of removing and reinstalling the cutter head 26, it is difficult to install the cutter head 26 back to its original position. When the cutting roller 25 drives the cutter head 26 to cut the core body, the height of the cutter head 26 protruding from the surface of the cutting roller 25 is insufficient, resulting in the gap between the cutter head 26 and the cutting table 12 being too large when the cutting roller 25 drives the cutter head 26 to cut the core body. The cutting depth of the core body by the cutter head 26 is insufficient, resulting in the inability to completely cut the core body. Therefore, after the cutter head 26 is maintained or replaced, the cutter head 26 needs to be repaired or replaced. The gap between the cutter head 26 and the cutting table 12 is adjusted, so that the cutter head 26 maintains an accurate cutting depth on the core body. When the gap between the cutter head 26 and the cutting table 12 is adjusted, the number of turns of the No. 1 servo motor 23 is controlled to drive the No. 1 adjusting screw 24 to rotate a corresponding number of times. Under the rotation action of the No. 1 adjusting screw 24, the No. 1 slider 22 is driven to slide along the No. 1 slide rail 21, thereby driving the cutting roller 25 and the cutter head 26 to move up and down, and then the gap between the cutter head 26 and the cutting table 12 is adjusted, so that the cutting depth of the core body by the cutter head 26 is accurate.

[0042] While the No. 1 slider 22 slides along the No. 1 slide rail 21, the No. 2 slider 28 slides along the No. 2 slide rail 27, stably limiting the two ends of the cutting roller 25, thereby improving the stability of the cutting roller 25 when moving. During the movement and operation of the No. 2 servo motor 29, the No. 1 limiting rod 211 is limited by the No. 1 limiting plate 212, thereby improving the stability of the No. 2 servo motor 29 during the movement and operation.

[0043] Embodiment 2: According to Figure 1 , Figure 3 , Figure 4 , Figure 5 and Figure 8 As shown, the monitoring mechanism 3 includes a mounting frame 31, a limiting groove is arranged inside the mounting frame 31, a limiting block 36 is slidably connected inside the limiting groove, a mounting plate 35 is fixedly connected to the side of the limiting block 36, a high-speed camera 34 is installed on the surface of the mounting plate 35, a No. 1 connecting frame 37 is fixedly connected to the side of the mounting plate 35, a measurement reference target 38 is installed at the bottom of the No. 1 connecting frame 37, an adjustment plate 33 is installed on the upper part of the high-speed camera 34, the adjustment plate 33 is threadedly connected to a No. 1 mounting adjustment screw 32, and the No. 1 mounting adjustment screw 32 is rotatably connected to the upper part of the mounting frame 31.

[0044] In the present invention, a monitoring mechanism 3 is installed on the upper part of the cutting frame 11 to adjust the left and right positions of the high-speed camera 34, so that it can accurately collect image information of the cut diaper core. When adjusting the position of the high-speed camera 34, the adjustment plate 33 and the high-speed camera 34 are driven to move by rotating the No. 1 installation adjustment screw 32, so that the left and right positions of the high-speed camera 34 can be accurately adjusted. During the movement of the high-speed camera 34, the mounting plate 35 drives the limit block 36 to slide along the limit groove of the mounting frame 31, and the movement of the mounting plate 35 and the high-speed camera 34 is limited by the limit block 36, thereby improving the stability of the high-speed camera 34 during the adjustment process.

[0045] Embodiment 3: According to Figure 1 , Figure 3 , Figure 4 and Fig. 9 As shown, the limiting mechanism 4 includes a No. 3 slide rail 41 and a No. 2 adjusting screw rod 44. The No. 3 slide rail 41 is fixedly installed on the cutting frame 11. The No. 3 slide rail 41 is slidably connected with a No. 3 slider 42 inside, and a No. 3 servo motor 43 is fixedly connected to the side of the No. 3 slide rail 41. The output end of the No. 3 servo motor 43 passes through the surface of the No. 3 slide rail 41, and the output end of the No. 3 servo motor 43 is fixedly connected to the No. 2 adjusting screw rod 44. The No. 2 adjusting screw rod 44 is rotatably connected to the No. 3 slide rail 41. The upper part of the No. 3 slider 42 is fixedly connected with a No. 2 connecting frame 45, and the No. 2 connecting frame 45 is threadedly connected with a No. 2 mounting adjusting screw rod 46. One end of the No. 2 mounting adjusting screw rod 46 is rotatably connected to a limiting frame 47. The upper part of the limiting frame 47 is fixedly connected with a No. 2 fixing plate 49, and the side of the limiting frame 47 is fixedly connected with a No. 2 limiting rod 410, which is plugged into the No. 2 connecting frame 45, and the surface of the limiting frame 47 is rotatably connected with a rotating roller 48.

[0046] During the cutting process of the diaper core, the width of the core is calculated by the size monitoring system 6, and the control parameters are generated according to the width of the processed core and transmitted to the No. 2 servo control system 52. The No. 3 servo motor 43 is controlled to rotate by the No. 2 servo control system 52, so as to accurately adjust the position of the limit frame 47 and the rotating roller 48, so that they can stably limit the two sides of the core. Before the initial cutting of the diaper core, according to the initial core width, the No. 2 installation adjustment screw 46 is rotated to drive the limit frame 47 and the rotating roller 48 to adjust the position. During the adjustment process, the No. 2 limit rod 410 is connected with the No. 2 connecting frame 45 to limit the movement of the limit frame 47, thereby improving the stability of the movement of the limit frame 47.

[0047] The use method and working principle of this device are as follows: the diaper core is inserted from the middle of the feed roller assembly 14 and then passes out from the middle of the discharge roller assembly 15. After the diaper core is loaded and connected, the cutting roller 25 and the cutter head 26 are driven by the second servo motor 29 to rotate, and the cutter head 26 is used to continuously cut the core. The cut core passes under the high-speed camera 34, and the high-speed camera 34 will capture images of the cut diaper core, and at the same time, the image of the measurement reference target 38 is captured as a reference for the size monitoring system 6 to calculate the cutting size of the core. The length of the cut core is accurately calculated. Specifically, when it is detected that the length of the cut core is too long, the control parameter generation module 63 calculates and generates the control parameter and transmits it to the No. 1 servo control system 51. The No. 1 servo control system 51 increases the rotation speed of the No. 2 servo motor 29, thereby increasing the cutting speed of the cutter head 26 on the moving core, thereby reducing the length of the cut core. When the length of the cut core is too short, the rotation of the No. 2 servo motor 29 is reduced according to the above control logic, thereby lengthening the size of the cut core.

[0048] During the cutting process of the diaper core, the width of the core is calculated by the size monitoring system 6, and the control parameters are generated according to the width of the processed core and transmitted to the second servo control system 52. The second servo control system 52 controls the rotation of the third servo motor 43, thereby accurately adjusting the positions of the limit frame 47 and the rotating roller 48;

[0049] Before the initial cutting of the diaper core, according to the width of the initial core, the second installation adjustment screw 46 is rotated to drive the limit frame 47 and the rotating roller 48 to adjust the position;
