Description

Heating device of spreader box.{The heating apparatus of spread box}

The present invention relates to a spreader box of a soft capsule molding machine, and more specifically, to a heating device for the spreader box to keep the liquid gelatin provided in the inner space of the spreader box from hardening.

.Generally, a soft capsule molding machine is equipped with a spreader box symmetrically on both left and right sides, and the spreader box supplies liquid gelatin onto a casting drum that rotates at low speed. In addition, the casting drum rotates at a constant speed to cool the liquid gelatin into a sheet, and surrounding guide rollers tow the solidified gelatin sheet of the casting drum and supply it to the molding device. At this time, the molding device laminates a pair of gelatin sheets pulled by left and right guide rollers and encapsulates them by cutting the edges while injecting a chemical solution between them.

Here, the spreader box of the soft capsule molding machine receives mixed and stirred liquid gelatin from the storage tank and supplies it to the casting drum rotating at low speed.

In particular, since the thickness of the gelatin sheet in the spreader box is different depending on the type and amount of chemical liquid, etc., the amount of gelatin supplied upward to the casting drum can be adjusted by adjusting the opening width of the outlet by changing the height of the blocking plate of the spreader box. It is well-equipped. At this time, the inner space of the spreader box is provided with a heating device to keep the liquid gelatin contained inside the inner space from hardening when supplying gelatin to the casting drum.

However, the internal space of the spreader box is limited, and in particular, when mixed and stirred liquid gelatin is supplied from the storage tank, high pressure exceeding the set pressure is generated for various reasons such as air, viscosity, and density difference, and liquid gelatin is oversupplied. , oversupplied gelatin overflows out of the spreader box, contaminating the surrounding area. And when the liquid gelatin overflows like this, the operation of the soft capsule molding machine is stopped before the viscous liquid gelatin hardens, and all the connecting components around the spreader box are separated one by one, and then the spreader box is removed. Each must be cleaned thoroughly.

In addition, even after production is completed, the spreader box must be disassembled and cleaned for each lot, which causes the inconvenience of having to install and demount the heater and sensors separately each time, and causes disconnection of connectors due to frequent disassembly. It was done.
