Abstract
The utility model relates to a wire breaking detection device of a multi-wire cutting machine. The wire breaking detection device comprises guide rollers, a wire mesh is wound around the guide rollers, and polycrystalline silicon is placed on one side portion of the wire mesh. A metal wire is located on the outer side of the wire mesh. The two ends of an electric wire are connected to the metal wire, and the electric wire is connected with two junction boxes, a two-kilohm resistor, a twenty-four-volt power source, and a PLC in series. The wire breaking detection device has the advantages that the risk of an error shutdown is reduced, influences on the slice qualification rate caused by the shutdown are reduced, and working efficiency can be improved.
Description
Technical field
The utility model relates to cutting machine field, and particularly a kind of multi-line cutting machine cuts off line detector.
Background technology
Current traditional multi-line cutting machine, all with the cutting of metal steel wire, metal steel wire has very strong conductive capability, after metal steel wire gauze disconnects, High Rotation Speed due to guide wheel, metal steel wire can be thrown away, encounter on the baffle plate of installation of machine frame or guide wheel side, cause the fluctuation of gauze voltage, according to the size of magnitude of a voltage fluctuation, judge whether gauze breaks, cutting liquid also has certain conductive capability, when cutting liquid is thrown in baffle plate or frame, also can cause certain voltage pulsation, cause sometimes mistakenly stop machine, cause inefficiency to wait a bit shortcomings.
Utility model content
For the weak point existing in the problems referred to above, the utility model provides a kind of multi-line cutting machine broken thread detector.
For achieving the above object, the utility model provides a kind of multi-line cutting machine broken thread detector, comprising:
Deflector roll, is wound around gauze on described deflector roll, and described gauze sidepiece is placed with polysilicon;
Metal wire is positioned at described gauze outside;
Electric wire two ends are connected on described metal wire, are in series with two terminal boxes, 2k Ω resistance, 24V power supply and PLC controller on described electric wire.
Preferred as the utility model, described gauze is that resin thread is wound in.
As the utility model, further improve, described electric wire is connected with described metal wire by the clip at two ends.
The beneficial effects of the utility model are: equipment has reduced the risk of mistakenly stop machine, reduce because shutdown causes the impact on section qualification rate, the plurality of advantages such as increase work efficiency.
Accompanying drawing explanation
Fig. 1 is the structural representation of a kind of multi-line cutting machine broken thread detector of the utility model.
In figure: 1, deflector roll; 2, polysilicon; 3, gauze; 4, metal wire; 5, electric wire; 6, clip; 7, terminal box; 8, PLC controller; 9,24V power supply; 10,2k Ω resistance.
The specific embodiment
As shown in Figure 1, a kind of multi-line cutting machine broken thread detector described in the utility model embodiment, comprising: deflector roll 1, on described deflector roll 1, be wound around gauze 3, and described gauze 3 sidepieces are placed with polysilicon 2; Metal wire 4 is positioned at described gauze 3 outsides; Electric wire 5 two ends are connected on described metal wire 4, are in series with two terminal boxes 7,2k Ω resistance 10,24V power supply 9 and PLC controller 8 on described electric wire 5.Described gauze 3 clip 6 that described electric wire 5 passes through two ends for resin thread is wound in is connected with described metal wire 4.
Equipment has reduced the risk of mistakenly stop machine, reduces because shutdown causes the impact on section qualification rate, the plurality of advantages such as increase work efficiency.
One wires, a ground protection resistance, two terminal boxes; at the two ends of the axis of deflector roll, each fixes a little terminal box; when needs connection metal line; only the two ends of a wires need to be clipped in respectively on the clip in terminal box; the electric current of 24V power supply like this; will pass through metal wire, arrive on the input terminal of PLC controller digital quantity input module, become a high level signal input is capable.
When the metal wire of deflector roll axis direction, after the resin thread being disconnected cuts off, the electric current of 24V power supply cannot arrive PLC controller by metal wire, and what in PLC controller digital-quantity input terminal, receive is a low voltage signal.Once what receive in PLC digital-quantity input terminal is low voltage signal, just sends halt command, avoids finding time of gauze.
The positive pole of 24V power supply is connected to metal wire, the resistance of the 2k Ω that connected, and this 2k Ω resistance effectively guaranteed, when metal wire positive pole is encountered frame when (frame is connected with ground wire), can be excessive because of electric current, damage 24V power supply.
On the both sides of deflector roll axis, respectively installed a terminal box additional, metal clip has been housed in terminal box, can make metal wire connect very easily.
During concrete use: in the both sides of deflector roll, four angles that on gauze, line of cut the most easily throws away, consider the convenience of installation, select, on two angles of deflector roll below, terminal box is installed.By the suitable aluminum wire of a segment length, two ends are clipped in respectively on the metal clip of terminal box, and aluminum wire is very near near gauze, and distance is in 1CM.
When multi-line cutting machine is in cutting process, because certain reason causes after the line of cut disconnection on gauze, the line of cut that metal wire will be thrown away on gauze cuts off.
When being contained in the other metal wire of deflector roll axis; after the resin thread cut-out being disconnected; in the digital-quantity input terminal of controlling at PLC, can go into one by high level to low level variation, PLC, after receiving low level signal, will send halt command and can send alarm.
The effect of 2k Ω protective grounding resistance is while avoiding metal wire to connect one end direct ground connection of positive source; can, because electric current is excessive, cause power supply to damage, after the 2k resistance of having contacted in the line; will reduce the electric current after plus earth, avoid the damage of electric elements.
If need to restart cutting after solution fault, only need to again one section of new metal wire be connected in two other terminal boxes of deflector roll axis.
The foregoing is only preferred embodiment of the present utility model, be not limited to the utility model, for a person skilled in the art, the utility model can have various modifications and variations.All within spirit of the present utility model and principle, any modification of doing, be equal to replacement, improvement etc., within all should being included in protection domain of the present utility model.
