Description

Technical Field

[0001] This utility model relates to the field of dressing cutting technology, and in particular to a cutting device for silver ion dressings. Background Technology

[0002] Pathogens such as Staphylococcus aureus, Candida, and Escherichia coli can easily multiply on wounds, making infected wounds difficult to heal. Medical dressings are protective coverings placed over wounds to help control bleeding, prevent infection, and absorb secretions. Silver can kill 650 different pathogens. Its bactericidal mechanism is that silver can block electron transport within bacteria, increasing the stability of bacterial DNA and thus weakening bacterial cell replication. Silver can also damage bacterial structure and receptor function, forming insoluble, ineffective metabolic compounds. Therefore, silver ion dressings require auxiliary slitting processing during production.

[0003] Existing slitting equipment is not convenient for cleaning the surface of dressing tapes. Since dressing tapes are prone to adhering to dust, debris and other tiny particles during production, transportation or storage, if they are not thoroughly removed before slitting, these impurities will be embedded in the slitting surface with the cutting blade, resulting in rough product edges and an increased risk of bacterial growth, which directly affects the integrity and biocompatibility of the silver ion antibacterial coating. Therefore, this application provides a slitting device for silver ion dressings to meet the needs. Utility Model Content

[0025] like Figure 1 and Figure 2As shown, the embodiment of this utility model provides a silver ion dressing slitting device, including a slitting frame 1, a base frame 2 installed at the bottom of the slitting frame 1, and leveling knobs 3 installed at the four corners of the bottom of the base frame 2. The base frame 2 and the leveling knobs 3 are threaded together. Through the threaded connection between the base frame 2 and the leveling knobs 3, the height of the four corners of the device can be finely adjusted by rotating the leveling knobs 3 to ensure that the slitting frame 1 is in a horizontal state and to avoid the device shaking during operation.

[0026] The slitting frame 1 is horizontally fixed with a receiving platform 25 at its top. A winding roller 4 is symmetrically rotated on the top of the slitting frame 1. A servo motor 5 for assisting the rotation of the winding roller 4 is installed on the outer side of the slitting frame 1. The slitting frame 1 has an installation port for the end of the winding roller 4 to be installed. A positioning cavity is provided at the installation port.

A rotating motor 12 for rotating the auxiliary rotating column 13 is mounted on one of the protruding blocks. The slitting blade 15 is composed of two semi-circular blades. A collar 14 is provided on the outer side of the slitting blade 15. The two collars 14 are fixed together by bolts. A positioning bolt 17 is threaded on one collar 14. A positioning hole 171 is drilled on the rotating column 13. The positioning hole 171 and the positioning bolt 17 are fitted together.

[0029] The slitting blade 15 is fixed by the collar 14 bolt and the positioning bolt 17 is inserted into the positioning hole 171. Different specifications of blades can be quickly replaced. With the length scale line of the scale plate 16, the slitting width can be precisely adjusted to meet the production needs of multi-specification silver ion dressings.

[0030] The other collar 14 is provided with a limiting strip 141 protruding from it, and a limiting groove 131 is horizontally formed on the outer side of the rotating column 13. The limiting strip 141 and the limiting groove 131 slide together.

A scale plate 16 is embedded at the top outer edge of the rotating column 13. The scale plate 16 is engraved with length scale lines. Through the scale plate 16, the position of the collar 14 after adjustment can be effectively determined during operation.

[0031] like Figure 1 , Figure 4 and Figure 5 As shown, a protruding block is provided at the top of the slitting frame 1, and a lower pressure roller 18 is rotatably provided at the protruding block. A dust collection assembly 19 for surface cleaning of the auxiliary dressing tape 24 is installed at the top of the slitting frame 1.

A number of dust collection holes are installed at equal intervals in the bottom and top of the cleaning chamber of the dust collection box 20. The number of dust collection holes are connected to the guide tube 23. The guide tube 23 is connected to the dust collection chamber. The air outlet of the guide tube 23 is connected to the air inlet of the industrial vacuum cleaner.

[0032] The dust and debris on the surface of the dressing tape 24 are removed before the slitting process by the dust suction component 19, which has a dual design of cleaning brush 22 and suction holes, thus avoiding contamination of the slitting surface by impurities and improving product quality.

[0033] The working principle of the technical solution provided by this utility model is as follows: The leveling knobs 3 at the four corners of the base frame 2 adjust the level of the equipment through threads. During installation, the end of the winding roller 4 is inserted into the installation port. The positioning component 6 in the positioning cavity at the installation port pushes the positioning insert 7 into the end of the winding roller 4 through the ejection spring 9 on the guide rod 8. Pulling the protruding ring 10 can realize the quick fixing and installation of the winding roller 4. The winding roller 4, which is symmetrically rotated on the top of the slitting frame 1, is driven to rotate by the servo motor 5 to realize the active conveying of the dressing tape 24. During operation, the dressing tape 24 passes through the dust suction component 19, the pressure roller 18 and the slitting component 11 in sequence from the winding roller 4. The pressure roller 18 and the slitting blade 15 work together to ensure that the dressing tape 24 remains flat during slitting. The guide rod 21 inside the dust collection box 20 in the dust collection assembly 19 guides the movement of the dressing tape 24 and causes the cleaning brush 22 to rotate and clean the two sides of the dressing tape 24. The dust collection holes at the bottom and top are connected to the dust collection chamber through the guide tube 23. The industrial vacuum cleaner is started to achieve synchronous dust adsorption during the slitting process. In the slitting assembly 11, the rotating column 13 is driven to rotate by the rotating motor 12. The slitting blade 15 mounted on it is composed of two semi-circular blades. The collar 14 is fixed by bolts. The positioning bolt 17 is inserted into the positioning hole 171 of the rotating column 13 to achieve axial positioning. The limiting strip 141 cooperates with the limiting groove 131 of the rotating column 13 to prevent circumferential movement. The scale plate 16 embedded on the top of the rotating column 13 can intuitively adjust the slitting width. The rotating column 13 is driven to rotate by the rotating motor 12, which drives the slitting blade 15 to rotate, thereby slitting the dressing tape 24.
