Description

Technical Field

[0001] This utility model relates to the technical field of dressing production equipment, specifically to a composite device for silicone gel foam dressings. Background Technology

[0002] Silicone gel foam dressings are used to cover non-chronic wounds on the body surface and absorb wound exudate. They have been widely used in clinical medical applications. This type of product has a wide range of uses and a large demand, while patients' quality requirements for these products are constantly increasing. In today's industrial production, the composite application of materials is becoming increasingly widespread. Traditional composite processes, such as thermoforming and adhesive bonding, have some limitations. Thermoforming may affect the physical properties of the material, leading to deformation or performance degradation; adhesive bonding may introduce chemical residues, affecting the product's breathability, safety, and environmental friendliness. Currently, most polyurethane foam and PU film are bonded by applying adhesive to the PU film and then bonding it to the foam, or by using a full-lamination process. This process results in poor breathability of the PU foam, failing to provide a better healing environment for patients, increasing the risk of wound infection and prolonging healing time.

[0003] Based on the above, this utility model proposes a composite device for silicone gel foam dressings, which can effectively solve the above problems. Utility Model Content

[0005] This utility model is achieved through the following technical solution: A composite device for silicone gel foam dressings includes a composite roller and a heating roller arranged vertically, and vertical plates distributed on both sides of the composite roller and the heating roller. The vertical plates have grooves extending in opposite directions vertically, and a first mounting seat and a second mounting seat are installed in the grooves. The two ends of the composite roller are rotatably connected to the first mounting seat, and the two ends of the heating roller are rotatably connected to the second mounting seat. The surface of the composite roller is provided with a plurality of arrayed dots, where the dots are non-composite areas and the remaining areas are composite areas.

[0006] According to the above technical solution, as a further preferred technical solution, the bottom of the upright plate is fixedly connected to a bottom plate, and the top of the upright plate is fixedly connected to a top plate.

[0007] According to the above technical solution, as a further preferred technical solution, the top plate is fixedly connected to a lifting mechanism for driving the composite roller to move up and down. The lifting mechanism includes a lifting cylinder installed on the top plate. The telescopic end of the lifting cylinder is fixedly connected to the lifting plate, and both sides of the lifting plate are fixedly connected to the first mounting base.

[0008] According to the above technical solution, as a further preferred technical solution, one end of the composite roller is fixedly connected to the output end of the first motor, and the first motor is fixedly connected to one of the first mounting seats.

[0009] According to the above technical solution, as a further preferred technical solution, one end of the heating roller is fixedly connected to the output end of the second motor, and the second motor is fixedly mounted on the base plate.

[0010] Compared with the prior art, this utility model has the following advantages and beneficial effects: This utility model provides a composite device for silicone gel foam dressings.
