Abstract
The invention discloses a locking device of an air valve switch, which is arranged on the air valve switch and is characterized by comprising a sealing cavity, wherein a movable locking member is arranged in the sealing cavity and corresponds to a limiting block of the air valve switch and a gap position of a shell, a spring is sleeved on the locking member, an air hole is formed on the sealing cavity, and the sealing cavity is connected with an air compression device through the air hole. In the locking device of the air valve switch, two states of locking or unlocking the air valve switch are realized by adopting the combination of air pressure and spring force, the locking device is reasonable and compact in structure, and normal operation of spinning is not affected.
Description
Technical field:
The present invention relates to a kind of locking device of air valve switch, more particularly, is on ring spinner in broken yarn processing device, the device that air valve switch is locked.Produce for ring spinning, belong to technical field of textile machine.
Technical background:
In the past, applicant has successively applied for that number of patent application is 201110158644.X and 201110236299.7, two applications for a patent for invention of the broken yarn processing device of title ring spinner in the present invention.Above-mentioned two applications for a patent for invention all utilize the pressure state of yarn to twizzle, and different principle under guide and two kinds of states of broken yarn is designed two broken yarn processing device that utilizes the ring spinner of air valve switch principle.Above-mentioned two kinds of technical schemes solve the broken yarn problem occurring in ring spinning process effectively, normal spinning and broken yarn state can automatically switch, there is significant effect, but find through practice, also there is following problem: in ring spinning process, except two kinds of states of normal spinning and accidental broken yarn, also have another kind of state, when will doffing and change overhead cop, the full cylinder of cop repeats again spinning process one time.In this process, fine spining machine will stop, and on whole machine, all the cop of spindle will be changed.Now, on whole fine spining machine, all ingot position yarn all disappears to the pressure of twizzle, and under this state, existing broken yarn processing device can not be processed well.Therefore, in order to make the air valve switch can be in this course, yarn to twizzle pressure elimination situation under, keep normal spinning state, to after the operation of doffing completes, start normally spinning, be necessary within this period of time, air valve switch collective is locked.Cross after this period, then collective's releasing locking state, spin normally, and in time broken yarn processing is carried out in broken yarn ingot position.
Goal of the invention:
For above-mentioned situation, the present invention is to provide a kind of device that the air valve switch of broken yarn processing device on ring spinner is locked, and by locking device of the present invention, can effectively switch in and doff in operation, the opening and closing of broken yarn processing device.
It is as follows that the present invention realizes the technical scheme that above-mentioned purpose adopts, a kind of locking device of air valve switch, be installed on air valve switch, it is characterized in that: described locking device comprises annular seal space, in annular seal space, be provided with movable locking part, locking member is corresponding to the interstitial site of limited block and the housing of air valve switch, and spring housing is loaded on locking member, on annular seal space, offer pore, annular seal space is connected with air compression plant by pore.
Further:
In annular seal space, be provided with guide pillar, guide pillar has the cavity of hollow, locking member one end by spring top clamping in annular seal space, the other end of locking member is movable end, the movable end of locking member is located in the cavity of guide pillar, the movable end of locking member, corresponding to the gap between limited block and housing, is provided with sealing ring on locking member.
Described air compression plant comprises gas-distributing pipe, and gas-distributing pipe is connected with the pore on annular seal space, and main gas tube is connected with gas-distributing pipe, and air compressor is connected with main gas tube.
The locking device of air valve switch of the present invention, utilizes the combination of air pressure and spring force, reaches locking or does not lock two kinds of states of air valve switch, rational in infrastructure, compact, do not affect spinning normal operating.
Below by the drawings and specific embodiments, the invention will be further described.
Brief description of the drawings:
Fig. 1 is the locking device structure schematic diagram of embodiment of the present invention air valve switch.
Fig. 2 is the not locking state schematic diagram of locking device of embodiment of the present invention air valve switch.
Fig. 3 is the locking device locking state schematic diagram of embodiment of the present invention air valve switch.
Drawing reference numeral explanation: twizzle 1, yarn 2, pressure regulating block 3, twizzle turnover panel 4, compression spring 5, housing 6, valve rod 7, limited block 8, air nozzle 14, front magnetic assembly 16, rear magnetic assembly 17, positioning chamber 19, restores alignment pin 20, locking member 36, sealing ring 37, spring 38, pore 39, spring base 40, seal cover 41, gas-distributing pipe 42, main gas tube 43, cavity 44, guide pillar 45, cavity 451, air valve switch 100.
Detailed description of the invention:
As Fig. 1, shown in Fig. 2 and Fig. 3, the locking device of air valve switch of the present invention, be installed on housing 6, in housing 6, be provided with limited block 8, described locking device comprises cavity 44, cavity 44 is annular seal space, in the present embodiment, cavity 44 is by housing 6, seal cover 41 is combined to form, in cavity 44, be provided with guide pillar 45, locking member 36 is installed in cavity 44, locking member 36 one end are spring base 40, holding out against in the bottom of cavity 44 by spring 38 is on seal cover 41, locking member 36 other ends are movable end, can move up and down along guide pillar 45, the movable end of locking member 36 is corresponding to the gap between limited block 8 and housing 6, in the present embodiment, guide pillar 45 has the cavity 451 of hollow, the movable end of locking member 36 is located in the cavity 451 of guide pillar 45, and along moving up and down in cavity 451, sealing ring 37 is installed on locking member 36, by sealing ring 37, tightening seal between locking member 36 and guide pillar 45.On cavity 44, offer pore 39, gas-distributing pipe 42 is connected with cavity 44 by pore 39, and main gas tube 43 is connected with gas-distributing pipe 42, and main gas tube 43 can be connected with input compressed-air with air compressor (not shown).
Operation principle of the present invention is as follows:
1, in the time of yarn doff: as shown in Figure 3, open air compressor switch, compressed air enters gas-distributing pipe 42 from air compressor by main gas tube 43, entered in the annular seal space being formed by seal cover 41 and sealing ring 37 by pore 39 again, compressed air promotes locking member 36 and moves, Compress Spring 38, the movable end of locking member 36 props up in the gap between limited block 8 and housing 6, so just lock air valve switch 100, make limited block 8 in the time that yarn 2 has pressure or pressure to eliminate to twizzle 1, guarantee that limited block 8 is failure to actuate, air valve switch is in locking state, now, yarn can complete doff operation.
2, normally under spinning state: as shown in Figure 2, close air compressor switch, in main gas tube 43, air pressure is recovered atmospheric pressure, causes air pressure in annular seal space to recover atmospheric pressure, at this moment spring 38 resiliences, make locking member 36 return recovery original state, air valve switch is unlocked, and now, broken yarn processing mechanism returns to duty.At this moment, if broken yarn, yarn 2 is eliminated the pressure of twizzle 1, and at compression spring 5 and front magnetic assembly 16, under the effect of rear magnetic assembly 17, limited block 8 is with ovable valve stem 7 to move, and air valve is opened, and will produce like this rove and cut off action.
About operation principle and the mode of broken yarn processing device, the earlier application with reference to applicant: number of patent application is 201110158644.X and 201110236299.7, does not repeat them here.
