Abstract

The utility model relates to the technical field of a flat knitting machine, in particular to a yarn changing device. The yarn changing device comprises a yarn changing base and a plurality of electromagnets; a mounting seat is fixedly arranged on the yarn changing base; the electromagnets are arranged at the front end of the mounting seat; the rear end of the mounting seat is vertically and slidably connected with a plurality of sliding blocks corresponding to the electromagnets; the top of the mounting seat is rotatably connected with a plurality of needle feeding swinging rods corresponding to the electromagnets; and one end of each needle feeding swinging rod is pressed against the top of the corresponding electromagnet, and the other end of each needle feeding swinging rod is connected with the corresponding sliding block. According to the yarn changing device provided by the utility model, the sliding blocks are controlled to slide up and down so as to drive the needle feeding swinging rods to swing, thus, the electromagnets are electrified or de-energized to realize yarn changing actions; the structure of the yarn changing device is simple and rational; the cost is low, the installation is convenient; and the performance is stable and the use is convenient.

Description

Yarn changing unit

Technical field:

The utility model relates to the flat machine technical field, relates in particular to a kind of yarn changing unit that flat machine is used.

Background technology:

Computerized flat knitting machine is a kind of crosspointer plate latch needles weft knitting loom; Its triangle device is just as one group of plane cam; The stitch of knitting needle can get in the conduit of cam, moves triangle device, forces knitting needle in the needle tray of needle plate, to do elevating movement clocklike; And collude the action with needle through pin, just can yarns be become knitted fabric.Knitting needle is in uphill process, and coil progressively withdraws from pin and colludes, and opens needle, and withdraws from needle and hang on the shank; Knitting needle is in the decline process, and pin catches on the yarn that new pad is put, and its tractive is bent to coil; Original coil of while is then deviate from pin and is colluded; New coil passes from old coil, is together in series with old coil, and the coil string that numerous knitting needles is made into connects mutually and formed knitted fabric.

The yarn changing unit of existing Computerized flat knitting machine be electromagnet get when electric will with change the iron block jack-up that the yarn slide block is connected; And when electromagnet cuts off the power supply; Iron block loses that being supported under the gravity effect descends falls back to the normal position, and the continuous rising of iron block thus, descending drives the reciprocating action of changing the yarn slide block and reach the purpose of changing yarn.Yet existing yarn changing unit complex structure is difficult for assembling, and serviceability is unstable.

The utility model content:

The purpose of the utility model is exactly the deficiency that exists to prior art and a kind of yarn changing unit of rational in infrastructure, easy for installation, stable performance is provided.

To achieve these goals, the technical scheme of the utility model employing is:

Yarn changing unit; Include and change yarn base, a plurality of electromagnet, change on the yarn base and be fixed with mount pad, a plurality of electromagnet are arranged on the front end of mount pad; The rear end of mount pad vertically slidely connects a plurality of sliding shoes corresponding with electromagnet; The top of mount pad is rotatably connected to a plurality of corresponding with electromagnet pin forks that send, and send an end of pin fork to contact at corresponding electromagnet top, and its other end is connected with corresponding sliding shoe.

Offer connecting hole on the said sliding shoe, send the pin fork to extend in the connecting hole.

The bottom of said sliding shoe and change between the yarn base and be connected with spring.

The said pin fork that send is rotatably connected on the mount pad through support bar.

Said changing on the yarn base forms groove, and the bottom of electromagnet is stretched in the groove.

The top of said mount pad is fixed with top board, and top board is passed at the top of sliding shoe.

The rear end of said mount pad is fixed with spacing press strip.

Said electromagnet is fixed on the mount pad through installing plate.

The utility model beneficial effect is: the utility model includes and changes yarn base, a plurality of electromagnet, changes on the yarn base and is fixed with mount pad, and a plurality of electromagnet are arranged on the front end of mount pad; The rear end of mount pad vertically slidely connects a plurality of sliding shoes corresponding with electromagnet, and the top of mount pad is rotatably connected to a plurality of corresponding with electromagnet pin forks that send, and send an end of pin fork to contact at corresponding electromagnet top; Its other end is connected with corresponding sliding shoe; The utility model slides up and down to drive through the control sliding shoe and send the swing of pin fork, makes electromagnet energising or outage realize changing the yarn action, and is simple and reasonable; Cost is low; Easy for installation, stable performance, easy to use.

Description of drawings:

Fig. 1 is the structural representation of the utility model.

Fig. 2 is the structural representation at another visual angle of the utility model.

Fig. 3 is the decomposing schematic representation of the utility model.

The specific embodiment:

Below in conjunction with accompanying drawing the utility model is further described; See shown in Fig. 1～3 that yarn changing unit includes and changes yarn base 1, a plurality of electromagnet 2; Change and be fixed with mount pad 3 on the yarn base 1; A plurality of electromagnet 2 are arranged on the front end of mount pad 3, and the rear end of mount pad 3 vertically slidely connects the corresponding sliding shoe 4 of a plurality of and electromagnet 2, the top of mount pad 3 be rotatably connected to a plurality of and electromagnet 2 corresponding send pin fork 5; Send an end of pin fork 5 to contact at corresponding electromagnet 2 tops, its other end is connected with corresponding sliding shoe 4.

Offer connecting hole 41 on the sliding shoe 4, send pin fork 5 to extend in the connecting hole 41, make that can depress an end that send pin fork 5 when sliding shoe 4 glides makes and send the pin fork 5 swings, easy for installation, connect reliable.The bottom of sliding shoe 4 and change and be connected with spring 6 between the yarn base 1 makes sliding shoe 4 upwards to reset automatically.

Send pin fork 5 to be rotatably connected on the mount pad 3 through support bar 7, easy for installation.Change and form groove 11 on the yarn base 1, the bottom of electromagnet 2 is stretched in the groove 11, and the location is convenient.

The top of mount pad 3 is fixed with top board 8, and top board 8 is passed at the top of sliding shoe 4, makes sliding shoe 4 slide steadily.The rear end of mount pad 3 is fixed with spacing press strip 9, carries out spacing to sliding shoe 4.Electromagnet 2 is fixed on the mount pad 3 through installing plate 10, and is easy for installation.

The utility model slides up and down to drive through control sliding shoe 4 and send the pin fork 5 swings, makes electromagnet 2 energisings or outage realize changing the yarn action, and simple and reasonable, cost is low, and is easy for installation, and stable performance is easy to use.

Certainly, the above only is the preferred embodiment of the utility model, so all equivalences of doing according to the described structure of the utility model patent claim, characteristic and principle change or modify, includes in the utility model patent claim.
