When braiding single face fabric, can use forward and backward any one side to weave.Before and after also having single face wheel turn over interweave, stripping stockinette etc., along with development of times, the yarn of various raw material varieties is more and more; The difference of performance is also bigger; The technological requirement that adds braided fabric again is higher, can produce phenomenons such as fabric not knocking over of next door, dropped stitch, broadside, does not reach perfect effect; Defect rate is higher, and some technology also can't be produced.

The utility model content

The purpose of the utility model provides a kind of head cam system of computer flat knitting machine, and it can solve problems such as fabric not knocking over of next door, dropped stitch, broadside effectively.

In order to solve above-mentioned technical problem; The technical scheme of the utility model is: a kind of head cam system of computer flat knitting machine; Comprise the cam system base plate, the cam system base plate is provided with and blocks the circle triangle, and the said circle triangle that blocks is arranged on the position, the corresponding left and right sides when weaving the knitting needle withdrawal of needle.

Block the circle triangle and be lifted to the height of setting to the knitting needle in the preceding needle-bar, be higher than the height of former reset triangle, its needle position in the back the move up and down bottom gap of knitting needle of needle-bar braiding more little better, but the knitting needle that weaves in the back needle-bar that can not collide, rub.Knitting needle dislocation middle position be best in the needle-bar before and after when braiding, and the knitting needle before utilizing in the needle-bar is pushed down, stopped back needle-bar knitting needle when weaving and moves up and down and be difficult for the coil of knocking over, makes it can play the pressure knocking over, reaches the effect of normal braiding.

In the utility model cam system blocking the circle triangle utilize obverse rest knitting needle control, help to weave the knitting needle upper density higher, be difficult to knocking over and widening is frequent, the coil of no tractive control, the problem that in the braiding process, occurs.Blocking the circle triangle is to be raised to certain altitude to the rest knitting needle, stops corresponding knitting needle when braiding, to be difficult for knocking over and the loose major function of floating easily of coil, after function of use finishes; Be raised to the rest knitting needle of certain altitude; Under the effect of density triangular, return to original position, can not have side effects; Can enlarge the raw material that can not be suitable for originally, the scope of yarns, improve the qualification rate of braided fabric.

Description of drawings

Below in conjunction with the accompanying drawing and the specific embodiment the utility model is done further detailed explanation.

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

Fig. 2 is the utility model working state schematic representation.

The specific embodiment

As shown in Figure 1, the head cam system of the computer flat knitting machine of the utility model comprises the cam system base plate.

Knitting needle 3 is divided into braiding knitting needle 7, blocks circle knitting needle 9 and rest knitting needle 10 (being the non-circle knitting needle that blocks) according to the function in different phase, and is as shown in Figure 2.Because braiding knitting needle 7 knitting needle when withdrawal of needle begins to move up and down; Original coil that has hung on the knitting needle is higher owing to density, and coil is had knitting needle in arms, when knitting needle rises, follows immediately; Needle latch on the knitting needle can not rise coil and can't knocking over; And new yarn gets into the pinhock of knitting needle, and especially technological requirement narrowing back knocking over is more difficult, so just causes and can't normally weave.

The single face fabric is when braiding, and technological requirement needs widening, and particularly revolution is few at interval; The weaving textile that widening is more frequent because just continuously frequent widening, below the fabric of braiding seldom or do not have a tractive; So the coil 8 that on braiding knitting needle 7, has just formed is loose; Float easily, can not normally weave, dropped stitch, broadside, mashed limit etc. can occur.

The utility model cam system base plate is provided with and blocks circle triangle 2, and the said circle triangle 2 that blocks is arranged on the position, the corresponding left and right sides when weaving knitting needle 7 withdrawals of needle.

The increase of blocking circle triangle 2 is to be set in cam system 1 forward and backward corresponding withdrawal of needle left and right position, mainly utilizes corresponding rest knitting needle 10 to be controlled at the stable of knitting needle knocking over, lopping in the braiding process.Block circle triangle 2 and be applicable to that single face braiding, stripping elastic force and front and back single face wheel turn over and interweave etc. that its shape can be designed to monomer or assembly respectively according to the cam system of different type of machines.

On the forward and backward part of original cam system, be provided with respectively and block circle triangle 2; As shown in Figure 2; Before the circle triangle 2 that blocks that increases on the needle-bar 6 coupling cam systems 1 play the height of setting to preceding needle-bar 6 interior knitting needles 3, the height of raising is a height H as shown in Figure 1, is higher than the height of former reset triangle 4; Its needle position in the back the move up and down bottom gap of knitting needle of needle-bar 5 braiding more little better, but knitting needles 3 of braiding in the back needle-bar 5 that can not collide, rub.Knitting needle 3 dislocation middle positions are best in the needle-bar of front and back when braiding; Back needle-bar 5 coil 8 that braiding knitting needle 7 moves up and down and is difficult for knocking over when braiding is pushed down, stopped to knitting needle 3 before utilizing in the needle-bar 6; Make it can play the pressure knocking over, reach the effect of normal braiding.

Flat machine is the directional transverse braiding; Set about circle triangle 2 also is so block; Its position is a corresponding surface; Braiding knitting needle 7 then blocks circle triangle 2 and rises in advance or simultaneously and block circle knitting needle 9 when withdrawal of needle, stop the coil 8 that stops on the corresponding surface braiding knitting needle 7, makes the obverse braiding knitting needle 7 knocking overs normal work of rising.

The foregoing description limits the utility model never in any form, and every employing is equal to the technical scheme that replacement or the mode of equivalent transformation obtain and all drops in the protection domain of the utility model.
