3, summary of the invention:
In order to overcome the deficiencies in the prior art, the purpose of this utility model provides a kind of Sewing machines with automatic thread trimming device.
The utility model is achieved by the following technical solution: it comprises workbench, is installed in Sewing machines main frame and pedal above the workbench, it also comprises automatic thread trimming device in addition, this automatic thread trimming device comprises heating wire cutter and negative pressure suction spool, the heating wire cutter is installed in negative pressure and inhales the spool top, negative pressure inhale needle plate that the spool top is arranged on Sewing machines near, the heating wire cutter is connected with power supply by lead.
Above-mentioned described automatic thread trimming device also comprises controller and photoelectric sensor, and the signal output part of photoelectric sensor connects the signal input part of controller, and the output of controller is connected the signal input part of heating wire heater circuit.
Above-mentioned described automatic thread trimming device also comprises pneumatic inductive switch, pneumatic inductive switch is connected the middle part of tracheae, one end of tracheae connects negative pressure and inhales spool, pin type air valve on the other end connecting pin pedal of tracheae, and the signal output part of pneumatic inductive switch connects the signal input part of controller.
Above-mentioned described negative pressure is inhaled spool and can be made up of with the plastic cement pipe that is enclosed within the copper pipe afterbody the copper pipe of front end
The utility model compared with prior art has following advantage: 1) automatic thread trimming device adopts the heating wire cutter, and number of parts is little, and is simple in structure, low cost of manufacture; 2) do not need to lubricate, lubricating oil can not be bonded on the cloth, guarantees product quality; 3) the heating wire cutter can be changed easily, and maintenance cost is low; 4), make equipment advanced more in conjunction with original existing electric sewer; 5) photoelectric sensor is installed, can survey the people when work, ability preheating heating wire cutter, when Sewing machines carries out trimming, signal is opened and sent to pneumatic inductive switch, makes controller further improve heating wire cutter temperature, so that trimming, this control mode is saves energy effectively, has prolonged the heating wire cutter life simultaneously.
4, description of drawings:
Below in conjunction with accompanying drawing the utility model is done detailed explanation:
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the partial view of sewing machine host part among Fig. 1;
Fig. 3 is the structural representation that the utility model heating wire cutter and negative pressure are inhaled spool;
Fig. 4 is control circuit figure of the present utility model.
5, the specific embodiment:
As Fig. 1, Fig. 2, shown in Figure 3, the utility model comprises workbench 1, is installed in Sewing machines main frame 2 and pedal 3 above the workbench 1, it also comprises automatic thread trimming device in addition, this automatic thread trimming device comprises heating wire cutter 4 and negative pressure suction spool 5, heating wire cutter 4 is installed in negative pressure and inhales spool 5 tops, negative pressure inhale needle plate 6 that spool 5 tops are arranged on Sewing machines near, heating wire cutter 4 is connected with power supply by lead.
As Fig. 1, shown in Figure 4, automatic thread trimming device also comprises controller 7 and photoelectric sensor 8, and the signal output part of photoelectric sensor 8 connects the signal input part of controller 7, and the output of controller 7 is connected the signal input part of heating wire heater circuit 9.Automatic thread trimming device also comprises pneumatic inductive switch 10, pneumatic inductive switch 10 is connected the middle part of tracheae 11, one end of tracheae 11 connects negative pressure and inhales spool 5, pin type air valve 12 on the other end connecting pin pedal 3 of tracheae 11, the signal output part of pneumatic inductive switch 10 connects the signal input part of controller 7.
Negative pressure is inhaled spool 5 and can be made up of with the plastic cement pipe 14 that is enclosed within copper pipe 13 afterbodys the copper pipe 13 of front end.
The utility model operation principle is: as Fig. 1, Fig. 2, Fig. 3, shown in Figure 4, the utility model is a kind of electric sewer, on pedal 3, be connected with pin type air valve 12, pin type air valve 12 is three-way air valves, the air intake of three-way air valve connects compressor, two delivery outlets of three-way air valve connect the driving cylinder that negative pressure is inhaled spool 5 and cloth-pressing device respectively, when the people leaves Sewing machines and stops to step on pedal 3, pin type air valve 12 is closed, pneumatic inductive switch 10 disconnects and photoelectric sensor 8 does not have output signal, the output pin A of controller 7 is in low level, controllable silicon D does not have conducting, heating wire heater circuit 9 cuts off the power supply fully, preparation before the people is sitting in Sewing machines, photoelectric sensor 8 output signals are to single-chip microcomputer (being controller 7) the inside, controllable silicon D in the single-chip microcomputer output signal control heating wire heater circuit 9 in certain angle of flow scope conducting, heating wire cutter 4 gets electric preheating, when the people steps on pedal 3 connection pin type air valves 12 acquisition sources of the gas preparation suction lines, gas in the pin type air valve 12 is delivered to negative pressure suction spool 5 by pneumatic inductive switch 10 and is made it end generation negative inspiratory pressure, pneumatic inductive switch 10 output signals are to single-chip microcomputer (being controller 7) simultaneously, controllable silicon D in the single-chip microcomputer output signal control heating wire heater circuit 9 in bigger angle of flow scope conducting, heating wire cutter 4 gets the electric higher temperature of bringing up to, and negative pressure suction spool 5 sucks the end of a thread and stick on the heating wire cutter 4 and fused.
