Abstract
The utility model discloses an injection molding machine safety door switch unit, injection molding machine safety door switch unit include inverter motor, converter, host computer, fluted disc, proximity switch, drive mechanism, the fluted disc is fixed in inverter motor's pivot, and proximity switch detects the rotation of the fluted disc teeth of a cogwheel, and proximity switch's signal transmission gives the host computer, and the host computer passes through converter control inverter motor according to preset program, and inverter motor actuation transmission mechanism carries out the action of switch door. This switching device can control the switch door process of emergency exit accurately.
Description
Technical field
This utility model relates to switching device.
Background technology
Existing injection molding machine safety door has two kinds of control modes: one is pneumatic control, and another kind is Electronic control. Both of which is defective: during pneumatic control safety door switch, and the speed controling ability of safety door is poor; During Electronic control, but owing to the Electrically operated gate big small distance of enabling is non-adjustable, cause that some occasion is opened the door apart from long, affecting the cycle of injection machine execution action, and need multiple mechanical strokes switch, travel switch is easily bad, inconvenience is installed, it is therefore desirable to improve injection molding machine safety door opening device.
Utility model content
Technical problem to be solved in the utility model is to overcome the above-mentioned deficiency of prior art to provide a kind of injection molding machine safety door switching device, is accurately controlled the switch gate process of safety door.
The technical scheme in the invention for solving the above technical problem is: injection molding machine safety door switching device includes frequency conversion motor, converter, host computer, fluted disc, proximity switch, drive mechanism; Fluted disc is fixed on the rotating shaft of frequency conversion motor, the rotation of the proximity switch detection fluted disc gear teeth, and the signal of proximity switch is transferred to host computer, and host computer is according to pre-set programs by Frequency Converter Control frequency conversion motor, and frequency conversion motor drive transmission device performs switch gate action.
Preferred drive mechanism includes Timing Belt, and the rotating shaft of frequency conversion motor is fixed synchronous pulley, and synchronous pulley drives Timing Belt.
Compared with prior art, the utility model has the advantage of: fluted disc and frequency conversion motor rotating shaft are fixed, proximity switch calculates the swing offset of frequency conversion motor rotating shaft by detecting the quantity of the gear teeth of fluted disc, these information can be stored by host computer, owing to passing through to detect number of teeth acquisition displacement information, can pass through to increase the quantity of the fluted disc gear teeth, arrange transmission ratios etc., accurately obtain the position of safety door, it is simple to be accurately controlled the speed of switch gate, stroke. Host computer according to the requirement of the condition of use, can be preset the program of host computer, accurately control the rotating speed of frequency conversion motor so that speed when controlling switch gate. During switch gate, proximity switch detection stroke host computer detects stroke, this process of persistent loop according to Stroke Control frequency conversion motor proximity switch, only exists one and controls loop, simplifies control flow. Adopt Timing Belt steady soft ground transmission, meet injection molding machine safety door and use the requirement of environment.
Accompanying drawing explanation
Fig. 1 is the part-structure schematic diagram of this utility model embodiment.
Fig. 2 is the structural representation of another direction of observation of Fig. 1.
Detailed description of the invention
Below in conjunction with accompanying drawing, embodiment, this utility model is further illustrated.
Injection molding machine safety door switching device, including frequency conversion motor, converter, host computer, fluted disc, proximity switch and drive mechanism.
As shown in Figure 1 and Figure 2, frequency conversion motor 3 is fixed on fixing plate 2, and fixing plate 2 is fixed on the lower section of track 1, sliding rail when track 1 moves as injection molding machine safety door. Frequency conversion motor 3 arranges converter, the velocity of rotation of Frequency Converter Control frequency conversion motor rotating shaft. Fluted disc 5 is fixed on frequency conversion motor rotating shaft, coaxially can rotate with speed with rotating shaft, and being arranged around of fluted disc 5 can sense the proximity switch 7 that the gear teeth of fluted disc rotate, and proximity switch 7 is fixed on fixing plate 2 by support 6. Also fixing synchronous pulley 4 in the rotating shaft of frequency conversion motor 3, can drive Timing Belt 8 when synchronous pulley 4 rotates with rotating shaft, Timing Belt 8 can drive safety door to perform switch gate action by other parts of drive mechanism.
Host computer is connected with converter, proximity switch 7 by electric wiring, and host computer can receive, process the signal of proximity switch 7. Being host computer setting command also by pre-set programs, host computer performs order and command signal is transferred to converter and controls frequency conversion motor 3.
Obviously, drive mechanism is not limited to Timing Belt, also can be replaced by other drive mechanism.
Use the process of this device switch injection molding machine safety door:
First detection, relevant parameter is set: be fixing owing to each gear teeth turn over the stroke of proximity switch, detect, by proximity switch 7, the number of teeth that fluted disc in switch gate process rotates to detect safety door and completely close or from completely closing to the total kilometres fully opened, total number of teeth, total kilometres, total number of teeth be stored in host computer from fully opening to. In actual switch door process, the speed of first half term, the second half speed is relatively slow, according to this feature, it is possible to set the stroke in the stroke of fast phase, at a slow speed stage by host computer.
When needing switch safety door, by the state modulator converter preset in host computer, start frequency conversion motor, frequency conversion motor drives drive mechanism to perform to open the door or action of closing the door, when execution action, proximity switch continues to detect the number of teeth that fluted disc turns over, and host computer is according to Tooth Number Calculation stroke. When the stroke that stroke arrives fast phase being detected, host computer is slack-off by the rotating speed of Frequency Converter Control frequency conversion motor; When detecting that stroke reaches total kilometres, host computer is stopped by Frequency Converter Control frequency conversion motor.
