Description

Technical Field

[0001] This utility model relates to the field of nursing pad processing technology, specifically to an environmentally friendly nursing pad cutting device. Background Technology

[0002] A search revealed Chinese Patent Publication No. CN220261236U, which discloses a slitting device for nursing pads. The device includes a base, where the rotation of a circular block drives the rotation of a square rod, which in turn drives the rotation of blades. A movable component allows a group of blades to move at equal distances along the square rod, thereby adjusting the cutting size of the nursing pads. This enables a single machine to slit nursing pads of different sizes, improving the machine's slitting efficiency. However, the existing technology described above has the following drawbacks: the nursing pads are prone to sliding and shifting during the slitting process, making manual pressing and fixing extremely inconvenient and risky. Therefore, an environmentally friendly nursing pad slitting device is proposed to address these problems. Utility Model Content

The front and rear sides of the inner wall of the housing 61 are provided with strip holes that are adapted to the movement trajectory of the U-shaped plate 65.

[0030] The electric push rod 51 drives the lifting plate 52 to move vertically, causing the slitting component 7 to approach or move away from the nursing pad, achieving precise control of the slitting height. The servo motor 62 drives the threaded rod 63 to rotate, causing the threaded block 64 to drive the U-shaped plate 65 to move horizontally, adjusting the lateral position of the slitting blade 707 to adapt to different slitting size requirements. The high-precision control of the servo motor ensures that the slitting spacing error is less than 0.1mm, meeting the strict standards of medical-grade nursing pads.

The moving block 706 can slide on the frame 705. The position is fixed by the snap-fit ​​structure between the rectangular frame 708 and the fixing spring 709, so as to realize the quick replacement and fine adjustment of the slitting blade 707. The slitting blade 707 is made of high carbon steel with a hardness of HRC58-62, ensuring that the cutting edge is flat and burr-free.

[0032] The pressing mechanism 8 includes a rectangular plate 81. The rectangular plates 81 are fixedly installed on both the left and right sides of the box body 61, and a pressing block 82 is fixedly installed on the bottom of the rectangular plate 81.

[0033] During use, check the stability of the base 1, frame 2, and support assembly 3. Confirm that the electrical components such as the electric push rod 51, servo motor 62, and rotary motor 702 are properly connected. The buffer spring 48 provides sufficient extension and retraction space, ensuring the limiting roller 49 remains in contact with the nursing pad. Clean the surface of the support base plate 33 to ensure it is free of impurities or residue, preventing scratches on the nursing pad during slitting. Lay the nursing pad flat on the support base plate 33, aligning the edges with the inside of the limiting roller 49, ensuring the material is flat and wrinkle-free. If multiple nursing pads need to be slit and stacked, each... Place release paper between layers to prevent adhesion. Control the rotation of threaded rod 63 via servo motor 62 to move U-shaped plate 65 to the target position. Calibrate the lateral spacing of slitting blades 707. Start electric push rod 51 to slowly lower lifting plate 52 so that slitting blades 707 contact the surface of nursing pad. Adjust to the appropriate depth via pressure sensor or manual testing. Adjust the rotation speed of rotary motor 702 according to the material of nursing pad to ensure a balance between cutting efficiency and edge quality. Press the start button. During operation, observe the equipment's vibration and noise status. If any abnormality is found, stop the machine immediately for inspection.

[0034] After slitting, the pressing mechanism 8 and slitting assembly 7 automatically reset. Remove the slitting nursing pad and check the quality of the slitting edges. If burrs, adhesion, or dimensional deviations occur, the parameters need to be readjusted or the blades replaced. Clean the debris on the support base plate 33 and limit roller 49. Use compressed air or a soft brush to clean the inside of the equipment to avoid residue affecting the next use. After daily use, clean and lubricate the slitting blade 707 to prevent rust or wear. Check the elastic coefficient of elastic elements such as the telescopic spring 43 and buffer spring 48 weekly. If loosening or breakage is found, replace them in time. Perform insulation testing on electrical components such as the servo motor 62 and rotary motor 702 monthly to ensure safe operation of the equipment.

[0035] Furthermore, any content not described in detail in this specification is existing technology known to those skilled in the art.

[0036] In summary, the environmentally friendly nursing pad slitting device, by setting a limiting mechanism 4 and a pressing mechanism 8, connects the fixed frame 41 and the moving frame 42 through a telescopic spring 43 to form an elastic buffer structure. The limiting roller 49 is connected to the bottom of the horizontal plate 44 through a vertical rod 45 and a buffer spring 48. During slitting, pressure is applied to the edge of the nursing pad to prevent material displacement or wrinkling and to ensure slitting accuracy. The pressure block 82 is fixed below the rectangular plate 81 and moves down synchronously with the adjusting component 6 during slitting. When the pressure block 82 contacts the moving frame 42, it will squeeze it down, so that the limiting roller 49 presses the surface of the nursing pad to prevent the material from bulging or shifting due to the impact of the blade. This achieves the purpose of preventing the nursing pad from shifting and solves the problem that the nursing pad is prone to sliding and shifting during the slitting process, which is extremely inconvenient and poses certain risks when manually pressing and fixing it.
