Description

Technical Field

[0001] This utility model relates to the field of medical adhesive coating machinery, specifically to a medical hot melt adhesive coating device. Background Technology

[0002] Hot melt adhesives are frequently used for bonding in the manufacturing process of medical devices. For example, hot melt adhesive is required to bond the substrate and breathable film of a breathable dressing.

[0003] Hot melt adhesive coating machines are generally used to bond two fabrics together using molten adhesive. During operation, the base fabric is coated with adhesive by an applicator roller, while the bonding fabric is bonded to the base fabric on a laminating roller. Finally, the two fabrics are cooled and pressed together by a pressing device to complete the bonding process. However, in practical use, it has been found that it is necessary to select either transparent or white hot melt adhesive depending on the specific application. Changing the hot melt adhesive requires cleaning the adhesive cartridge, which is inconvenient.

[0004] Therefore, a new technical solution is needed in this field to solve the above problems. Summary of the Invention

[0005] To improve or solve the technical problem of inconvenient cleaning of glue cartridges in existing technologies, this utility model provides a medical hot melt adhesive coating device. The medical hot melt adhesive coating device includes: a frame; a feeding structure, including a first unwinding roller for feeding a first material and a second unwinding roller for feeding a second material; a first coating structure, including a first abutting roller and a first spray nozzle spaced apart from the first abutting roller, the first spray nozzle being connected to a first hot melt adhesive cartridge suitable for containing transparent hot melt adhesive; a second coating structure, including a second abutting roller and a second spray nozzle spaced apart from the second abutting roller, the second spray nozzle being connected to a second hot melt adhesive cartridge suitable for containing white hot melt adhesive; a pressing structure, including a first pressing roller and a second pressing roller arranged opposite to each other, configured to press the first material and the coated second material together; and a winding structure mounted on the frame.

[0006] This invention relates to a medical hot melt adhesive coating device, comprising a frame, a feeding structure, a first coating structure, a second coating structure, a pressing structure, and a winding structure. The feeding structure includes a first unwinding roller and a second unwinding roller, capable of feeding a first material and a second material. The first coating structure is used for spraying transparent hot melt adhesive, and the second coating structure is used for spraying white hot melt adhesive. When spraying transparent hot melt adhesive, the first coating structure is used; when spraying white hot melt adhesive, the second coating structure is used. This avoids adhesive changes, reduces the frequency of cleaning the adhesive cartridge, and improves the coating efficiency of the hot melt adhesive coating device. Through the above configuration, this invention provides a medical hot melt adhesive coating device with a first coating structure and a second coating structure. By using the first coating structure for spraying transparent hot melt adhesive and the second coating structure for spraying white hot melt adhesive, it avoids adhesive changes, reduces the frequency of cleaning the adhesive cartridge, and improves the coating efficiency of the hot melt adhesive coating device.

[0007] Furthermore, a first steering column and a second steering column for changing the orientation of the first material are provided between the first unwinding roll and the first pressing roll; a third steering column for changing the orientation of the second material is provided between the second unwinding roll and the second pressing roll; and the first adhesive coating structure is provided between the third steering column and the second pressing roll.

[0008] Furthermore, the feeding structure also includes a third unwinding roller for feeding a third material; the third unwinding roller is arranged above the third steering column and on the side of the third steering column close to the second unwinding roller.

[0009] Furthermore, a fourth steering column is provided below the second abutment roller, the fourth steering column being configured to guide the second material from the second unwinding roller to the second abutment roller.

[0010] Furthermore, a collection trough is provided below the first and second glue spray heads.

[0011] Furthermore, the winding structure includes a guide roller arranged below the first pressing roller and a winding roller rotatably mounted on the frame.

[0012] In summary, compared with the prior art, this utility model has the following beneficial effects:

[0013] The first coating structure can be used for spraying transparent hot melt adhesive, and the second coating structure can be used for spraying white hot melt adhesive. When it is necessary to spray transparent hot melt adhesive, the first coating structure is used for coating, and when it is necessary to spray white hot melt adhesive, the second coating structure is used for coating. This avoids the need to change adhesives, thereby reducing the frequency of cleaning the adhesive cartridge and improving the coating efficiency of the hot melt coating device.
