Abstract
The utility model discloses a frequency changing speed regulating weft storing device which relates to a weft supplying device of a weaving machine. The utility model is mainly composed of control circuit board and an AC asynchronous motor and is characterized in that a high pressure frequency changing circuit is adopted to arrange all AC and DC frequency changing circuit boards including a rectifying and a filter circuits into the weft storing device to make the weft storing device become to a novel frequency changing speed regulating weft storing device which directly uses commercial power for working without depending on traditional special power boxes. With the omission of traditional heavy power boxes and the direct use of commercial power, the utility model brings much convenience to users, and the total cost is reduced obviously. In addition, the middle links are decreased, so that the reliability of the utility model is enhanced obviously.
Description
The utility model frequency control weft accumulator be a kind of be used for shuttleless loom for Weft handling device, can with domestic and international various gripper shuttle looms, Rapier looms and the supporting use of knitting machine.
Domestic and international various types of frequency control weft accumulators all need the configure dedicated power supply box to be its power supply in use at present.These power source special casees convert the lower alternating current of voltage earlier to by the inner high-power transformer civil power that voltage is higher (China is 50Hz three-phase 380V or single-phase 220V), resupply weft accumulator through rectifying and wave-filtering or after becoming direct current.Power supply box output voltage difference because of each weft accumulator manufactory production.The weft accumulator of different model generally can not use with a kind of power supply box, so bring many inconvenience for user's use.
At above-mentioned shortcoming, the utility model weft accumulator is intended to not rely under the prerequisite of power supply box, and a kind of novel frequency control weft accumulator that can directly use civil power is provided.
For achieving the above object, done following innovation in the design of the present utility model: (one) has adopted the high-pressure frequency-conversion circuit of operating voltage greater than 300V.(2) the high-pressure frequency-conversion circuit directly uses the high voltage direct current that obtains from the commercial power rectification.(3) whole variable frequency regulating speed control circuit boards that will comprise rectification circuit are packed in the weft accumulator, weft accumulator are become do not rely on the power source special case and directly use the novel frequency control weft accumulator (being electromechanical integration equipment) of an integral body of civil power work.
Structure of the present utility model: mainly constitute by control circuit board (4) and AC asynchronous motor (3), its technical characterictic is that control circuit board (4) is contained in the weft accumulator, near motor (3) next door, circuit board (4) comprises rectifier (10), current-limiting resistance (11), filter condenser (12) and field ring shift switch (14～19) etc., the input of rectifier (10) is connected on the attaching plug (2) through fuse (9), attaching plug directly is inserted on the commercial power socket (1) during use, and the output of rectifier (10) links to each other with filter condenser (12) through current-limiting resistance (11).On the axle of motor (3), be equipped with, connect attaching plug (2), promptly construct a complete novel frequency control storage line device around yarn dish (7) and storage yarn drum (6).The operation principle of control circuit is that civil power is introduced by socket (1), be divided into two-way by attaching plug (2) through fuse (9): route rectifier (a 10) rectification, obtain a high voltage direct current (more than 300V) by current-limiting resistance (11) and through capacitor (12) filtering, the inverter circuit that this high voltage direct current is formed through field ring shift switch (14～19) becomes the alternating current of virtual value and changeable frequency, and drive motor group (12); Another road is through wattage transformer (21) step-down, obtains direct-current power supply field ring shift switch driver (28) about 12V by rectifier (22) rectification and voltage-stablizer (23) voltage stabilizing; Direct current about 12V obtains 5V direct current supply microcontroller (27) crystal (25) through voltage-stablizer (24) provides microcontroller (27) stable clock frequencies, the user can control the duty of microcontroller (27) by switch (26), microcontroller (27) sends various control signals for field ring shift switch driver (28) according to fuzzy control principle, field ring shift switch driver (28) is strict to drive field ring shift switch (14～19) by control signal, at last by the different synthetic required alternating current of open and close combination of field ring shift switch (14～19).
The utility model is owing to directly use civil power, bring great convenience to the user, particularly to being configured weft accumulator but want to increase the old user of weft accumulator quantity, with no longer for the weft accumulator intending increasing because of manufacturer's difference, the capacity of power supply box is can not compatibling problem anxious.Because of having saved heavy power supply box, the manufacturing cost of weft accumulator system is obviously reduced in addition,, the reliability of weft accumulator is significantly improved more because of the minimizing of intermediate link.
Fig. 1 is the mechanical structure schematic diagram of the utility model frequency control weft accumulator.Among the figure: 1, commercial power socket; 2, weft accumulator attaching plug; 3, AC asynchronous motor; 4, control circuit board; 5, cover plate; 6, storage yarn drum; 7, around the yarn dish.
Fig. 2 is the schematic diagram of the utility model frequency control weft accumulator control circuit.Among the figure: 2, weft accumulator attaching plug; 9, fuse; 10, rectifier; 11, current-limiting resistance; 12, capacitor; 13, bleeder resistor; 14～19, field ring shift switch; 20, motor winding; 21, wattage transformer; 22, rectifier; 23, voltage-stablizer; 24, voltage-stablizer; 25, crystal; 26, switch; 27, microcontroller; 28, field ring shift switch driver.
The installation of the utility model weft accumulator, use are very easily, and the user only need attach it to plug on the support and just can use.Because rotating speed of motor is control automatically, need not the user and be provided with.For the loom of existing weft accumulator, supporting the utility model weft accumulator is also very convenient, and weft accumulator is rack-mount, picks out civil power in loom electric cabinet or first wife's weft accumulator power supply, receives weft accumulator by socket (2), and weft accumulator can operate as normal.
