Abstract
The utility model discloses an edge cutting device for a loom. The edge cutting device comprises a heating cord R, a switch K and a transformer T which are installed on an outer edge supporting cover of the loom, the heating cord R and the switch K are in series connection through conducting wires, the primary side of the transformer T is in connection with an alternative power source through the conducting wires, and the secondary side of the transformer T is connected with the heating cord R and the switch K which are in series connection through the conducting wires. The edge cutting device for a loom has high reliability without needing daily maintenance.
Description
Technical field
The device of the sheared edge weft yarn that the utility model uses when relating to a kind of loom shuttle changing specifically is that device is cut on a kind of limit that is used for loom.
Background technology
At present, it generally is that device is cut on mechanical shearing limit that device is cut on the limit of prior art, and this device is after using a period of time, and the blade place of its blade is easy to rust and cuts continuous limit weft yarn, to such an extent as to cause the flaw on the cloth cover.Especially when shearing a thick weft yarn or multiply weft yarn, this easier appearance of situation of cutting continuous limit weft yarn.In order to address the above problem, the limit must be cut old blade on the device and remove and more renew blade, perhaps old blade be ground and reinstall on the loom after sharp, but in this process, not only waste time and energy, and incured loss through delay the ordinary production of loom, caused loss to factory.In sum, the limit of prior art is cut device not only reliability is low but also need carry out regular maintenance.
The utility model content
The technical problems to be solved in the utility model is, overcomes the defective of above prior art, provides the high and limit that is used for loom that need not regular maintenance of a kind of reliability to cut device.
The technical solution of the utility model is, provide a kind of limit that is used for loom to cut device, it comprises and is installed in heating wire R, K switch and the transformer T that the outer temple of loom covers, described heating wire R and K switch are connected in series by lead, the primary side of described transformer T is connected by lead with AC power, and the secondary side of transformer T is connected by lead with heating wire R with the K switch that is connected in series.
After adopting above structure, the utility model compared with prior art, the utility model is used for the limit of loom and cuts the heating principle that device utilizes resistance (heating wire), can the limit weft yarn be scalded disconnected by heating wire when the loom shuttle changing, its reliability height has guaranteed the effect that cut on the limit.And the limit that the utility model is used for loom is cut device and be need not regular maintenance, can not incur loss through delay the ordinary production of loom owing to regular maintenance, has guaranteed the benefit of factory.
As improvement, the utility model is used for the limit of loom and cuts the potentiometer RP that device also comprises an adjustable voltage, regulates the effect of temperature to guarantee that further the limit is cut of heating wire by regulation voltage.
Description of drawings
Accompanying drawing is the circuit theory diagrams that device is cut on limit that the utility model is used for loom.
The specific embodiment
The utility model is described in further detail below in conjunction with the drawings and specific embodiments.
As shown in drawings, the utility model is used for the limit of loom and cuts device, comprise the heating wire R, K switch and the transformer T that are installed on the outer temple lid of loom (just the Unit Installation position is cut on the prior mechanical limit), the end of heating wire R and an end of K switch are connected in series with lead.In the present embodiment, use is the alternating current of 220V.
The primary side of described transformer T is connected by lead with AC power, the secondary side of transformer T is connected by lead with heating wire R with the K switch that is connected in series and is meant: the primary side of transformer T (input) is two inputs, is connected with zero line with the live wire of 220V AC power respectively by lead respectively; An output port of the secondary side of transformer T (output) is connected with another output port of transformer T through K switch, heating wire R, forms a series circuit.
The described limit that is used for loom is cut device and is also comprised potentiometer RP, described potentiometer RP one end is connected with the secondary side lead of transformer T, the other end of potentiometer RP is connected with heating wire R with the K switch that is connected in series, that is to say that potentiometer RP is connected in the series circuit of transformer T secondary side.In use can come regulation voltage to regulate the effect of temperature to guarantee that the limit is cut of heating wire by resistor R P.
Described K switch and potentiometer RP are the tap changer of an one, and the temperature of adjustable economize on electricity heated filament R when opening switch makes the limit cut the more convenient operation of device.
In the present embodiment, transformer T places in the power supply box, and the one tap changer of K switch and potentiometer RP is installed on the power supply box panel.
During the utility model work, transformer T changes the 220V alternating current into the 24V alternating current, and when loom started, tap changer was opened and by the voltage on this switch adjusting heating wire, heating wire R heating power is started working.Close when loom, close tap changer, stop power supply.
Transformer T in the utility model can also be the transformer T of input 380V; This is also in protection domain of the present utility model.
Claims (2)
