There are many different types of Blister Packaging Machine since the manufacturers are different. The performance of domestic and imported products varies too. Currently, there are three types of Blister Packaging Machines, namely platen type, rotary type and platen-rotary type Blister Packing Machines based on structure.
The forming of Blister Packaging Machine is divided into rotary type and platen type. For the platen type, the effect of positive pressure forming is superior to that of vacuum forming, which is adopted by rotary type. In addition, the heat sealing is divided into rotary type and platen type. The rotary type outshines the platen type with regard to the sealing effect.
Solutions are provided as follows
It may encounter problems during blister forming, heat sealing, etc. Solutions are provided as follows:
(1) Check whether the PVC film is acceptable;
(2) Check whether the temperature of heating device is appropriate;
(3) Check whether the surface of heating device is attached with PVC;
(4) Check whether the forming mould is acceptable, the cavity is smooth, and the air hole is unobstructed;
(5) Check whether the cooling system of forming mould works normally and efficiently;
(6) For rotary type Blister Packaging Machine, check whether the vacuum degree and exhausting rate of negative pressure reach the normal values and whether the pipeline is subject to abnormal spoilage;
(7) For platen type Blister Packaging Machine, check whether the compressed air of positive pressure is clean and dry, whether the pressure and flow reach the normal values and whether the pipeline is subject to abnormal spoilage;
(8) For platen type Blister Packaging Machine,check whether the forming mould is parallel to and clamps PVC, and whether there is air leakage.
(1) Check whether the aluminium foil is acceptable, and whether the heat sealing surface is coated with satisfactory thermosol;
(2) Check whether the temperature of heating device is appropriate;
(3) Check whether the operation of PVC or aluminium foil is subject to abnormal resistance;
(4) Check whether the heat sealing mould is acceptable, whether the surface is smooth, and whether the blisters can be inserted into the cavity of heat sealing mould smoothly;
(5) Check whether the grid in heating plate is distinct and consistent in depth;
(6) Check whether the cooling system of heat sealing mould works normally and efficiently;
(7) Check whether the pressure required by heat sealing is normal;
(8) Check whether the upper and lower heat sealing moulds are parallel.
(1) The safety protective cover is open;
(2) Insufficient pressure of compressed air;
(3) Insufficient heating temperature;
(4) Run out of PVC film or alumimium foil;
(5) Run out of drugs to be packed;
(6) Mechanical overload at some work stations;
(7) Circuit overload.
Apart from the problems mentioned above, various problems may be encountered during application, and therefore requires concrete analysis is required. Finding out root cause is key to eliminating and solving the problem.
