The utility model solves the problem of manually toggling a hand wheel to control the negative pressure in the coating cylinder of the coating machine by regulating the exhaust valve. The utility model has the advantage of scientific and reasonable structure, simple operation and fine voltage regulation, which greatly improves the automation level of coating machine.
Description
Technical field: this utility model relates to pharmaceutical machine equipment, and particularly the interior negative pressure of coating machine coating cylinder is by the invention of the negative pressure controlling organization of computer control.
Background technology: in the prior art, at pharmaceutical industry various plain sheets are wrapped up sugar-coats, bag water-soluble film clothing, the machine thin film of being surrounded by all adopts the special equipment of high-efficiency coating machine, in the course of the work, the vacuum control system of high-efficiency coating machine is to be controlled by the air mass flow size of exhaust valve, and the air mass flow of control exhaust valve is to stir the size that handwheel is regulated the exhaust valve air door by craft, can only be arranged on the end face of coating machine because of this valve, and the height of coating machine will generally all surpass the human body height, so its operation is very inconvenient, and, thereby the coating quality of reduction coating machine also very poor by the manual voltage regulation performance of controlling.
Summary of the invention: in view of the problem that known technology exists, the purpose of this utility model aims to provide a kind of scientific and reasonable for structure, and is simple to operate, voltage regulation performance height, the pharmaceutical machine high-efficiency coating machine negative pressure controlling organization that automaticity is strong.For achieving the above object, this utility model is finished as follows: the negative pressure controlling organization of this pharmaceutical machine high-efficiency coating machine, be by exhaust valve, cylinder and computer are formed, be provided with valve block by valve shaft in the described exhaust valve, cylinder and back cylinder before described cylinder is divided into by the mandrel upper piston, its feature is provided with rocking arm in the end of described valve shaft, one end of described rocking arm and the mandrel of described cylinder are hinged, the preceding cylinder of described cylinder and back cylinder are connected by the pore on trachea and the two electric control reversing valves of 3 position-5 way respectively, the control power supply is electrically connected with described computer about on the two electric control reversing valves of described 3 position-5 way, described computer is put with the negative pressure probe in the coating machine coating cylinder and is connected, and the pendulum angle of described rocking arm is 90 °.This utility model adopts the negative pressure in the omnidistance control of the computer coating machine coating cylinder, its voltage regulation performance is good, greatly improved the coating quality of coating machine, compared, had with known technology, scientific structure, easy to operate, the automaticity advantages of higher has solved and has manually stirred the handwheel problem of difficult when exceeding human body because of coating machine height, the of the present utility model design successfully is an important breakthrough of pharmaceutical machine industry.
Description of drawings: this utility model has following accompanying drawing:
Fig. 1 is a structure principle chart of the present utility model.
The specific embodiment: accompanying drawing has been represented structure of the present utility model and embodiment, further describes a relevant details of embodiment below more in conjunction with the accompanying drawings.The negative pressure controlling organization of this pharmaceutical machine high-efficiency coating machine, be by exhaust valve, cylinder 9 and computer 1 are formed, be provided with valve block 13 by valve shaft 14 in the described exhaust valve, described valve shaft 14 is by two bearing block supports on the valve body, cylinder and back cylinder before described cylinder 9 is divided into by the piston on the mandrel 10, described cylinder 9 is fixed on the body of coating machine by cylinder block 7 usefulness screws 8, the end of described valve shaft 14 is provided with rocking arm 12; end of rocking arm 12 and the mandrel of cylinder 9 10 is hinged by oscillating bearing 11; the preceding cylinder of cylinder 9 and back cylinder are respectively by trachea 6; 6 ' with the two electric control reversing valves 3 of 3 position-5 way on pore 5; 5 ' connect; control power supply 4 about on the two electric control reversing valves 3 of described 3 position-5 way; 4 ' is electrically connected; described computer 1 and the negative pressure in the coating machine coating cylinder are popped one's head in and 2 be electrically connected; negative pressure is popped one's head in and 2 sensed the interior negative pressure value of coating cylinder and notify computer 1; instruction that computer 1 sends to control two pores 5 by the power supply of 3 position-5 way pair electric control reversing valves 3 with described computer 1; 5 ' air inlet or give vent to anger, the pendulum angle of described rocking arm 12 is 90 °.During this utility model work, the negative pressure value that negative pressure probe 2 is surveyed is sent to computer 1 to signal, give vent to anger in the two electric control reversing valve 3 left holes 5 of control system instruction 3 position-5 way in the computer 1 or right hole 5 ' give vent to anger, in the present embodiment, computerized control system is provided with negative pressure probe 2 and detects once for ten seconds, if transmitted number of the negative pressure value that detects is not when computer 1 decoded value meets the negative pressure value that sets, computer 1 instructs the two electric control reversing valves 3 of 3 position-5 way to work at once, the negative pressure value of described setting is 100Pa～150Pa, when with pore 5 ' air inlet that cylinder before the cylinder is communicated with, piston (not shown) on cylinder 9 inner spindle 10 retreats, the pore 5 that is communicated with cylinder behind the cylinder is given vent to anger, cylinder mandrel 10 drives rocking arm 12 left-hand rotations simultaneously, and valve block 13 is closed, and negative pressure value reduces.When pore 5 air inlets that are communicated with cylinder behind the cylinder, piston-advance on the cylinder inner spindle 10, the pore 5 that is communicated with cylinder before the cylinder ' give vent to anger, cylinder mandrel 10 drive rocking arms 12 are turned right valve block 13 are opened simultaneously, increase the air draft flow, negative pressure value increases, because the negative pressure probe 2 under computer 1 control is constantly detecting negative pressure value, computer 1 constantly instructs two electric control reversing valve 3 gas transmissions of 3 position-5 way, make the exhaust valve flow meet needed negative pressure value in the coating machine coating cylinder always, so its coating quality is greatly improved, pharmaceutical machine high-efficiency coating machine negative pressure controlling organization according to this utility model design motif made will bring positive result of use to pharmaceutical industry.
