Description

Technical Field

[0001] The invention relates to the technical field of pharmaceutical packaging material coating, in particular to a PVDC coating device for producing pharmaceutical packaging materials with high barrier properties. Background Art

[0002] During the processing and production of some pharmaceutical packaging materials, polyvinylidene chloride (PVDC) is coated on the pharmaceutical packaging materials through coating equipment. PVDC has extremely high barrier properties and is excellent in blocking oxygen, moisture and odor. It plays a vital role in protecting the quality and safety of drugs.

[0003] However, the existing processing equipment has the following shortcomings:

[0004] Prior art, such as CN211587279U, this utility model belongs to the field of PVDC material production equipment, specifically discloses a PVDC coating equipment for producing pharmaceutical packaging materials with high barrier properties, including a workbench, a lifting frame, a storage box, a coating roller and a fixing device, wherein a conveying trough is provided on the workbench, and a symmetrical conveying frame is fixed to the inner bottom of the conveying trough, wherein a micro-speed motor is fixed in the conveying frame on one side, and a conveying roller is fixed at the output end of the micro-speed motor, and a conveying roller is rotatably arranged in the conveying frame on the other side, and the conveying rollers are connected by a conveyor belt; a plurality of fixing devices are fixed on the conveying belt, and the workbench is provided with a plurality of fixing devices, and the conveying rollers are connected by a conveyor belt; a plurality of fixing devices are fixed on the conveying belt, and the workbench is provided with a plurality of fixing devices, and the conveying rollers are connected by a conveyor belt; a plurality of fixing devices are fixed on the conveying belt, and the plurality of fixing devices are fixed on the conveying rollers; a ... Guide grooves are provided on both sides of the table, in which slide blocks are slidably connected, and a lifting frame is fixed on the slide block. Lifting cylinders are fixed on both sides of the workbench, and a lifting shaft is fixed on the output end of the lifting cylinder, and the lifting shaft is fixedly connected to the lifting frame, and a storage box is fixed on the lifting frame. This solves the problem that PVDC latex materials are often coated on the surface of drug packaging bags or drug packaging boxes during the production process of existing drug packaging materials, thereby providing moisture-proof, oxygen-blocking and other functions for the drugs. However, the coating of existing PVDC latex materials is all done manually, which is not only inefficient and has high labor costs, but also affects the production efficiency of drug packaging bags.

[0005] When the existing coating equipment is in use, it is not easy to control the temperature of the PVDC latex in the box, and it is easily affected by the temperature environment, and the temperature of the PVDC latex in the box is too high or too low. When the temperature of the PVDC latex in the box is too high, the viscosity of the latex may decrease, and the fluidity is enhanced, which makes it difficult to control the coating thickness during the coating process, and it is easy to have sagging, uneven thickness, etc. When the temperature is too low, the viscosity of the latex may increase, and the fluidity becomes worse. This will make the coating process difficult, and may cause uneven coating or even missing coating, which in turn causes the existing coating equipment to be inconvenient to control the temperature of the PVDC latex when in use, thereby affecting the coating effect.
