Detailed Implementation

[0025] To make the objectives, technical solutions and advantages of this utility model clearer, the utility model will be described in further detail below with reference to the accompanying drawings.

[0026] Example 1

[0027] See Figure 1This utility model provides a medical pad, including a packaging bag and a medical pad body inside. The medical pad body includes a bottom layer 1, a core layer 2, and a surface layer 3 arranged sequentially from bottom to top. The bottom layer 1 is a water-repellent layer, specifically a water-repellent non-woven fabric. The surface layer 3 is an absorbent layer, specifically a hydrophilic non-woven fabric. The core layer 2 includes an absorbent fiber layer and multiple absorbent particles evenly distributed within it (the absorbent particles located in the absorbent fiber layer will fall off and are in the form of tiny powder). The absorbent fiber layer can specifically be a wood pulp layer, and the absorbent particles can specifically be absorbent polymer particles. The structure of the core layer 2 can be found in the descriptions of application numbers CN 201921755112.2, CN 202122836517.2, CN 202011323903.5, or CN 201410306236.8. The bottom layer 1 and the top layer 3 have their four sides aligned and ultrasonically welded together to form a rectangular frame welded section, creating a bag-like structure. The core layer 2 is located within this bag-like structure, slightly smaller than the rectangular frame welded section, with its four sides positioned adjacent to the corresponding sides of the rectangular frame welded section (with small gaps to facilitate water absorption and expansion). The upper surface of the core layer 2 has absorbent particles (which may fall into the interlayer formed by the core layer 2 and the top layer 3), while its lower surface does not have absorbent particles (during preparation, they are absorbed through natural falling and the particle suction nozzle 20).

[0028] In this embodiment of the invention, the surface layer 3 comprises multiple layers of hydrophilic nonwoven fabric (specifically two layers, to prevent absorbent particles from passing through the surface layer 3). The multiple layers of hydrophilic nonwoven fabric are stacked together and their four sides are welded together by ultrasonic welding. The packaging bag is a rectangular bag that fits with the medical pad body and is made of two layers of dialysis paper (for easy sterilization) sealed on all four sides.

The pressure roller is arranged in a left-to-right direction and is located on the upper side of the core layer 2. The conveying speed of the negative pressure conveyor belt 10 is greater than the speed of the first pair of roller conveying devices 8 to ensure that the core layers 2 on it are evenly spaced.

[0033] The core layer traction device 18 is used to pull the core layer 2 backward, then diagonally downward to the front of the correction device 7 to form an inclined section (making it easier for the water-absorbing particles on the lower side of the core layer 2 to fall off during the bending and conveying process), then upward to the correction device 7, and then backward to the first pair of roller conveying device 8. Specifically, the core layer traction device 18 includes multiple (specifically 2-4) first traction rollers, a second traction roller below the front of the correction device 7, and a third traction roller below the rear of the correction device 7. The multiple first traction rollers are arranged side by side and are located behind the core layer unwinding device 6. The second traction roller is located below the rear of the first traction roller, and the third traction roller is located directly in front of the first pair of roller conveying device 8. Both the second and third traction rollers are provided with two limiting rings arranged side by side (coaxially). The two limiting rings are located on the adjacent outer sides of the left and right sides of the core layer 2 (there is a certain gap between the limiting rings and the corresponding sides of the core layer 2 to ensure correction adjustment). The core layer 2 output from the core layer unwinding device 6 passes through multiple first traction rollers, then through a second traction roller to form an inclined section, then upwards through the correction device 7, and finally backwards through a third traction roller. The first traction roller, the second traction roller, and the third traction roller are all arranged in the left-right direction.

It is used to receive naturally falling absorbent particles. Specifically, the powder receiving trough 19 may include a front inclined trough and a rear horizontal trough. The inclined trough is arranged diagonally downward from front to back and is located directly below the inclined section, while the horizontal trough is arranged along the front-to-back direction and is located directly below the correction device 7.

[0035] The composite molding device 11 is a roller-type ultrasonic welding structure. Its welding roller is located above the core layer 2, and its circumference has a H-shaped welding point area that mates with the core layer 2. This area is used to weld the four sides of the bottom layer 1 and the top layer 3. Specifically, the composite molding device 11 includes a welding platform (with a smooth upper surface) arranged in the front-rear direction, a second pair of roller conveying devices 21 directly behind the welding platform, a lower composite roller 22 adjacent to the front of the welding platform, an ultrasonic welding structure on the welding platform, and an upper composite roller 23 above the lower composite roller 22. The welding platform is flush with the negative pressure conveyor belt 10 and is located directly behind it. Both the lower composite roller 22 and the upper composite roller 23 are arranged in the left-right direction. The lower composite roller 22 is located adjacent to the rear of the negative pressure conveyor belt 10, and the upper composite roller 23 is located above the rear of the lower composite roller 22. The second pair of roller conveying devices 21 is located directly in front of the product slitting device 12 and includes two rubber rollers arranged side-by-side. The H-shaped welding area includes two annular welding area arranged side-by-side and a strip welding area between them. The two annular welding area are located at the left and right ends of the welding roller of the ultrasonic welding structure to weld the left and right sides of the product. They are located at the left and right ends of the surface layer 3 and adjacent to the outer side of the corresponding ends of the core layer 2, coaxially arranged on the circumference of the welding roller. The strip welding area is arranged in the left-right direction and is used to weld the area between the corresponding ends of two adjacent core layers 2 (the welding area is located adjacent to the front or rear of the core layer 2, corresponding to the front and rear ends of two adjacent products). One rotation of the welding roller is sufficient to weld one product.

[0036] The particle suction nozzle 20 is arranged in the left and right direction. It is located in front of the bottom layer 1, below the negative pressure conveyor belt 10 and the lower composite roller 22, and directly below the core layer 2. The suction port at the top of the nozzle faces the lower side of the core layer 2. It is used to absorb (the suction force should not be too large so as not to affect the rearward conveying of the core layer 2) the water-absorbing particles on the lower side of the core layer 2.

[0037] Specifically, in this embodiment of the invention, both the product slitting device 12 and the packaging slitting device are roller cutting structures, and each has a conveyor belt arranged in the front-to-back direction behind it (a second visual inspection structure can be installed above it).
