Abstract
A reeding machine short circuit self-stopping protection device is used for reeding machine short circuit self-stopping. Two ends of an input end of a transformer are respectively connected with a fuse and a control switch. Two ends of an output end of the transformer are respectively connected with two ends of a spreader, and a travel switch is in parallel connection with the spreader after being in series connection with a warp absorbing device. The reeding machine short circuit self-stopping protection device is characterized in that a normally open contact of a universal relay coil and a normally open contact of a universal relay are respectively installed at an input end of the transformer and an output end of the transformer, a start button is additionally installed at the input end of the transformer, the start button is in parallel connection with the normally open contact of the universal relay, and the universal relay coil is in parallel connection with the spreader. Due to the fact that the technology that the universal relay controls a circuit instantaneously is adopted, interference is little, sensitivity of action is high, and circuit damage to a reeding machine caused by a short circuit of external objective factors is effectively overcome, and therefore repair strength and repair cost are greatly reduced.
Description
Technical field
The present invention relates to a kind of cotton mill Weaving device, specifically Self-stop protector for short circuit of reeding machine, belong to the cotton spinning equipment technical field.
Background technology
At present, shown in Figure 2 in G177 type reeding machine at known reeding machine, sequence number 1 is fuse; Sequence number 2 is air switch; Sequence number 4 is transformer; Sequence number 5 is spreader; Sequence number 6 is travel switch; Sequence number 7 is for inhaling through device.Suction is all the 36V end that directly is connected on transformer 4 through device 7 and spreader 5, protects the facility protective effects not obvious although air switch 2 and fuse 1 etc. are housed; And inhaling through device 7 is all external equipment with spreader 5, in actual production, due to the accident contact of metal, is easy to cause electrical short-circuit on the denting frame, burns the transformer 4 in circuit, has strengthened the reeding machine maintenance cost.
Summary of the invention
For the reeding machine external short circuit that overcomes prior art can not automatic stop protection transformer deficiency; goal of the invention of the present invention is to provide a kind of Self-stop protector for short circuit of reeding machine; when the outside produces short circuit, the input of the power supply of the transformer that immediately breaks, thus the protection transformer is not burnt.
For achieving the above object, the two ends of type transformer input of the present invention are connected with fuse, control switch respectively, the two ends of transformer output are connected with the two ends of spreader, travel switch is in parallel with spreader after device is connected with suction, it is characterized in that: the input and the output that general-purpose relay coil and general-purpose relay normally opened contact are arranged on respectively transformer, and the input at transformer installs start button additional, start button is in parallel with the general-purpose relay normally opened contact, and the general-purpose relay coil is in parallel with spreader.
The present invention is due to the technology that adopts general-purpose relay moment control loop, disturbs littlely, and action highly sensitive can effectively overcome the circuit to reeding machine that the short circuit of extraneous objective factor causes and injure, thereby greatly reduce repair density and maintenance cost.
Description of drawings
Fig. 1 is circuit theory diagrams of the present invention;
Fig. 2 is the circuit theory diagrams of prior art.
Embodiment
As shown in Figure 1, transformer 4 of the present invention) two ends of input are connected with fuse 1, control switch 2 respectively, the two ends of transformer 4 outputs are connected with the two ends of spreader 5, travel switch 6 is in parallel with spreader 5 after device 7 is connected with suction, general-purpose relay coil 8 and general-purpose relay normally opened contact 9 are arranged on respectively input and the output of transformer 4, and the input at transformer 4 installs start button 3 additional, start button 3 is in parallel with general-purpose relay normally opened contact 9, and general-purpose relay coil 8 is in parallel with spreader 5.
Operation principle of the present invention is: first with control switch 2 closures, and crawl start button 3, transformer 4 energisings, and general-purpose relay coil 8 and spreader 5 also mutually deserved 36V electricity, spreader 5 is started working, general-purpose relay normally opened contact 9 closures, and reeding machine also begins normal operation.When the outside generation of denting short circuit; the 36V output of transformer 4 cuts off the power supply immediately; general-purpose relay coil 8 dead electricity; general-purpose relay normally opened contact 9 disconnects immediately; the 380V input power supply of transformer 4 disconnects immediately; whole down circuitry, reeding machine quits work, thereby has protected whole circuit.
