Embodiment 1

[0113] Goal: It is necessary to obtain 5 patches of molding specifications with a coating thickness of 0.1mm, a width of 170mm, and a length of 350mm.

[0114] use Figure 1 to Figure 7 equipment shown.

[0115] Methods include:

[0116] 1. In the hot-melt adhesive container 2 with a temperature control of 150°C, add the materials, and stir with the agitator 1 continuously for a long time. The color of the stirred materials is evenly mixed, and the glue reaches a molten state;

[0117] 2. Set the temperature of the flat nozzle slit coating cutter head 4 and the adhesive coating support roller 5 at 150°C, adopt a digital temperature controller, and the temperature control stability accuracy is ±0.5°C;

[0118] 3. Open the pneumatic switch 3 for ventilation, and after 3 minutes rely on the gravity of 5.95ml glue flow into the coating cutter head 4, then close the pneumatic switch 3;

[0119] 4. Adjust the pressure value of the precision pressure reducing valve 86 to 0.1bar, p...

Abstract

The invention relates to the field of medical equipment, in particular to hot melt adhesive preparation and coating integrated equipment and hot melt adhesive preparation and coating method. The equipment comprises an agitator, a melt coating assembly, a coating film assembly and a control assembly, wherein the melt coating assembly comprises a hot melt adhesive container, a pneumatic switch and a flat nozzle slit coating tool bit; the bottom surface of the hot melt adhesive container is provided with a material outlet, the material outlet is communicated with the flat nozzle slit coating tool bit, and the pneumatic switch is arranged on a communicated channel; and the coating film assembly comprises a back glue coating supporting roller used for bearing a coating film, and the coating film is clamped between the back glue coating supporting roller and the flat nozzle slit coating tool bit. According to the hot melt adhesive preparation and coating integrated equipment, small-batch and customized manufacturing of medical patches can be met.

Description

technical field [0001] The invention relates to the field of medical equipment, in particular to an integrated equipment and method for hot melt adhesive preparation and coating. Background technique [0002] At present, the small-batch production process of hot-melt adhesive patches includes: heating the container containing the hot-melt adhesive material to a preset temperature, using a stirrer to stir and mix the material for a long time, and then mixing and stirring the prepared hot-melt adhesive in a high-temperature state Pour into the coating device for release film coating, after the coating is completed, paste the backing, and finally cut to obtain the required patch product. [0003] During the transfer process of the hot melt adhesive material after stirring and mixing at high temperature, the temperature of the material is likely to drop during the operation process, and the material is semi-cured and difficult to add to the coating equipment. Rapid operation is ...
