Description
Technical field
This utility model relates to a kind of pharmaceutical equipment, particularly relates to the coating machine that a kind of kettle temperature can be controlled automatically.
Background technology
In medical solid preparation such as pill production process, to cover pill abnormal smells from the patient, protection against the tide, lucifuge in order reaching, to discharge purposes such as position and rate of release when the control pill uses, need carry out a Cotton seeds to pill.With sugar material or other can film forming coated materials at the outer surface of pill, become tight adhesion at one or more layers different thickness on surface, different elastic multifunction protection layer after making its drying, this multifunction protection layer just is called coating.
At present, the equipment that pill is carried out coating is called the coating machine, and existing coating machine is in operation; Temperature in its coating pan is generally all changing; Need manual work to keep watch on and control, thereby keep temperature to be positioned at about the rated temperature, strengthened the amount of labour; And go wrong easily, the underproof pill of some coatings appears.
The utility model content
The purpose of this utility model promptly is to overcome the deficiency of present technology, and the coating machine that provides a kind of kettle temperature to control automatically uses the strict control of PLC controller kettle temperature, can keep pill under rated temperature, to work.
This utility model is realized through following technical scheme: the coating machine that kettle temperature can be controlled automatically, comprise motor and coating pan, and described coating pan is through an actuating device; By the driven by motor rotation, it also comprises a controlled room temperature hot air apparatus and PLC controller, and described controlled room temperature hot air apparatus comprises constant temperature cabinet and blower fan; Constant temperature cabinet is provided with air inlet and air outlet; Also be provided with heater in the constant temperature cabinet, the control end of heater connects the PLC controller through an electromagnetic valve, and described air inlet connects blower fan; Air outlet is communicated in the coating pan through pipeline; Coating pan pot mouth is provided with seal glass, also is provided with a temperature sensor in the coating pan, and the signal output part of temperature sensor connects the PLC controller.
Described coating pan is a Corm Eleocharitis formula coating pan.
Described heater is adjustable heater strip of temperature or infrared heating device, and heater is used to the constant temperature cabinet heating.
Also be provided with an exhaust outlet on the described seal glass; After hot blast in the constant temperature cabinet got in the coating pan, the air pressure in the coating pan increased, if continue to increase after a certain amount of; Hot blast in the constant temperature cabinet can't get in the coating pan; So an exhaust outlet need be set, the hot blast in the constant temperature cabinet circles round in coating pan and discharges through exhaust outlet behind the circle again, also can take away a part of steam.
The operation principle of this utility model: the pill that will process is put into coating pan; Coating solution is sprinkled upon on the pill, installs seal glass, rated temperature in the pot is set on the PLC controller; Start blower fan, heater and motor respectively; Coating pan begins rotation, and this moment, pill began to do continuous complex track motion under the drive of coating pan, made coating solution to be wrapped in equably on the pill; Hot blast is arranged simultaneously to the pill dry tack free in the coating pan, make the pill surface form firm surface film fast.In the coating process, when kettle temperature was lower than rated temperature, heater promptly can Fast Heating; When kettle temperature reached rated temperature soon, heater promptly began slowly to heat; Reach rated temperature up to kettle temperature, heater promptly stops heating; When kettle temperature was lower than rated temperature once more, heater promptly began task again.Coating takes off seal glass and can pill be taken out after accomplishing.
The beneficial effect of this utility model is: use the strict control of PLC controller kettle temperature, can keep pill under rated temperature, to work, this utility model also has simple in structure, low cost and other advantages.
Description of drawings
Fig. 1 is the structural representation of this utility model;
