DETAILED DESCRIPTION

[0048] The directional words involved in this utility model are made based on the habits of this field, for example: front needle bed, rear needle bed, the front needle bed is the needle bed on the side that the operator directly faces and has the operation interface, and the rear needle bed is the needle bed on the side opposite to the front needle bed; the various components on the needle plate, such as needle grooves and knitting needles, are made based on the needle grooves on the needle plate of the flat knitting machine, and the needle grooves face the cylinder mouth (such as Figure 1 The arrow F in the figure is in the forward direction, away from the barrel mouth (such as Figure 1 The direction of the arrow B) is posterior, that is, the length direction of the needle groove is the front-to-back direction; the width direction of the needle groove is the inner-outer direction, the direction away from the paper surface is the outer direction, and the direction toward the paper surface is the inner direction; the depth direction of the needle groove is the up-down direction.

[0049] The present invention will be described in detail below with reference to the accompanying drawings and specific embodiments. Example 1

[0050] like Figure 1-2 As shown, this embodiment is a needle plate mechanism, including two needle beds Gq (see Figure 24 or 25) with the needle plate 8 on the rear needle bed Gh, a number of steel sheets 1 vertically arranged on the needle plate 8 and a number of needle grooves 4 formed by adjacent steel sheets 1, and a number of knockout plates 9 parallel to the front end of the needle plate, the knockout plates 9 are located in front of the corresponding positions of the steel sheets 1 and form the tube mouth a of the braided fabric with the front end of the needle plate 8; the needle plate mechanism of this embodiment also includes a number of spacers 2, which are arranged at the rear section of each needle groove, that is, the rear end of the spacer 2 is flush with the rear end of the needle groove 4, thereby the spacer 2 divides the rear section of the needle groove into two needle tracks 41 and 42 arranged on the left and right.

[0051] The structure of steel sheet 1 and spacer 2 is as follows Figure 3 The spacer 2 used in this embodiment is the first spacer. Its length is shorter than the length of the needle slot 4 and its length along the height direction is equal, that is, its length distribution along the height direction is basically the same. When this spacer 2 is placed in the needle slot rear section 4h, it forms an undivided front section 4q. In this embodiment, the needle slot front section 4q is shorter than the length of the knitting needle placed in the needle slot 4. Half of the needle slot width is compatible with the thickness of the thickest part of the placed knitting needle. Example 2

[0052] like Figure 4-6 As shown, this embodiment is a needle plate and knitting needle combination mechanism. Based on the needle plate mechanism of the above-mentioned embodiment 1, two knitting needles 31 and 32 arranged on the left and right and two control pins 51 and 52 respectively connected to the back of the needle bodies of the knitting needles 31 and 32 are further provided in each needle groove 4 of the needle plate mechanism.

[0053] like Figure 7 As shown, the knitting needles 31 and 32 have a hook 301, a needle tongue 302, a needle shaft 303 and a needle body 304. The two knitting needles 31 and 32 used in this embodiment are both second knitting needles. The thickness of the needle body of the second knitting needle is an uneven thickness structure along the length of the knitting needle. The thickness of the front part of the needle body is a thick part 3041 that is adapted to 1 / 2 the width of the needle groove, and the thickness of the back part of the needle body is a thin part 3042 that is not greater than the width of the needle track. The thick part is the thickest part of the needle body. Figure 6The two knitting needles 31 and 32 are placed opposite to each other in the needle groove, with the thick parts of the needle bodies touching each other. The lengths of the knitting needles 31 and 32 are both longer than the front section 4q of the needle groove, and the adjacent surfaces of the thick parts of the needle bodies are placed in contact with each other in the front section 4q of the needle groove that is not separated by the spacer 2. Most of the thin parts of the needle bodies of the knitting needles 31 and 32 are respectively arranged in the needle channels 41 and 42. The undivided front section of the needle groove 4 and the needle channel 41 (or 42) jointly accommodate the two second knitting needles 31 (or 32) of unequal thickness structures. When the two knitting needles 31 and 32 move forward (in the direction indicated by the arrow F in the figure) or backward (in the direction indicated by the arrow B in the figure), they are guided by the adjacent surface of the adjacent knitting needle and the groove wall of the corresponding side front section of the needle groove.

[0054] At least one needle clock 501 is positioned above each of the two control pins 51 and 52, which is pushed against by the corresponding knitting cam in the cam system T. When placed naturally without being pressed, the needle butt 501 is exposed from the needle slot. In this embodiment, the control pins are also provided with a needle clock 502, which is used to reset the knitting needles 31 and 32 when pushed against by the corresponding cam. A limiting protrusion 503 is provided below the control pins 51 and 52, and a limiting groove 401 is provided on the bottom surface of the needle slot 4 corresponding to the needle track position. The protrusion 503 cooperates with the limiting groove 401 to limit the forward movement of the control pin along the needle slot. The thickness of the control pins 51 and 52 is adapted to the width of the corresponding needle track 41 and 42, and they are guided by the side walls of the needle track during movement. Example 3

[0055] like Figure 8 As shown, this embodiment is a needle plate and needle assembly mechanism suitable for fully fashioned knitting. During fully fashioned knitting, one of the knitting needles 31 and 32 on the two needle tracks within a needle slot is in operation, while the other is inoperative. To this end, this embodiment also includes a selection mechanism in each needle slot. This selection mechanism consists of two needle selection units, which are respectively positioned on the corresponding two needle tracks 41 and 42 in each needle slot. This needle selection unit is commonly used and includes a pusher 61 (or 62) and a selector jack 71 (or 72). The pusher 61 (or 62) is positioned above the rear portion of the control stitch 51 (or 52) in each needle slot, and the selector jack 71 (or 72) is positioned above the rear portion of the pusher 61 (or 62). Therefore, the pushers 61 and 62 and the selector jacks 71 and 72 are all located at the rear end of the corresponding needle track. The needle selector 71, 72 is controlled by the knitting cam on the cam system T through the clock 702 and the upper front butt 701 thereon, and moves back and forth, and the rear butt 703 thereon pushes the push pieces 61, 62 to move forward, so that the gear slots 602 at different positions are engaged with the positioning core shaft, and the knitting needles are in different working positions, so that the knitting needles are in different knitting states.

[0056] The push pieces 61 and 62 are both provided with a plate clock 601 controlled by the pressure piece in the cam system of the flat knitting machine. The plate clock 601 is exposed to the needle path when it is not pressed by the pressure piece. At this time, the push pieces 61 and 62 do not act on the control stitches 51 and 52. The control stitches 51 and 52 are in a natural placement state without being pressed. The needle butt 501 is exposed to the needle groove and will be pushed by the corresponding knitting cam, so that the knitting needle moves forward in the needle groove and extends out of the tube mouth. During the movement, the control stitch is guided by the corresponding needle path side wall, and the knitting needle is guided by the groove wall on one side of the needle groove and the adjacent side of the adjacent knitting needle, and moves in the undivided front section 4q of the needle groove.

[0057] like Figure 9 As shown, when the push piece 61 (or 62) is pressed by the pressure piece in the cam system of the flat knitting machine, the pressure piece presses down the plate clock 601 of the push piece, and the push piece 61 (or 62) presses the control pin, such as the control pin 51, so that the control pin 51 is elastically deformed, and the needle clock 501 on it enters the needle track and is not pushed by the cam, and the corresponding knitting needle 31 does not work. At this time, the limiting protrusion 503 of the control pin 51 is embedded in the limiting groove 401. If the other knitting needle 32 in the same needle groove is in a working state, since the front parts of the needle bodies of the two knitting needles 31 and 32 in the same needle groove are in contact with each other, the non-working knitting needle 31 may be driven due to friction. However, the setting of the upper limit protrusion 503 of the control pin 51 and the upper limit groove 401 of the needle track in this embodiment limits the forward movement of the non-working knitting needle 31. Example 4

[0058] like Figure 10 As shown, this embodiment is a needle plate mechanism, including needle plates 8 respectively arranged on the front needle bed of the flat knitting machine, a plurality of steel sheets 1 arranged perpendicularly on the needle plate 8 and a plurality of needle grooves 4 formed by adjacent steel sheets 1, and a plurality of knockout plates 9 arranged parallel to the front end of the needle plate and at the front end of the steel sheets. The knockout plates 9 and the front end of the needle plate 8 constitute the tube mouth a of the knitted fabric; similarly, this embodiment is also provided with a plurality of spacers 2, which are arranged at the rear section 4h of each needle groove 4 to divide the rear section of the needle groove into two needle channels 41 and 42 arranged on the left and right, and the part not separated by the spacer 2 forms the front section of the needle groove 4.

[0059] The length of the spacer 2 in this embodiment is relatively short, so that the length of the undivided needle groove front section 4q is longer. The structure of the steel sheet 1 and the spacer 2 in this embodiment is the same as that in embodiment 1, which can be seen in FIG. Figure 3 . Example 5

[0060] like Figure 11-13As shown, this embodiment is a needle plate and knitting needle combination mechanism, which is based on the needle plate mechanism of the above-mentioned fourth embodiment, and also includes two knitting needles 31 and 32 arranged left and right in each needle groove 4 on the needle plate, control pins 51 and 52 respectively connected to the rear of the two knitting needles 31 and 32, and a selection mechanism arranged in each needle groove.

[0061] The knitting needles 31 and 32 used in this embodiment are first knitting needles. The needle body thickness of the knitting needle is uniform along the length of the knitting needle, and the thickness is adapted to the width of 1 / 2 of the needle groove. Figure 14 Therefore, when the spacer 2 is positioned in the rear section of the needle groove, to ensure that the two knitting needles 31 and 32 complete their knitting motion, the length of the undivided front section of the needle groove must be no less than the length required for the needles to reciprocate forward or backward within the groove. Therefore, the first knitting needle is entirely contained within the undivided front section 4q of the needle groove. During knitting, the adjacent surfaces of the needle shafts of the needles 31 and 32 fit together to form one guide surface for the other needle. The other guide surface is formed by the groove wall on the corresponding side of the front section 4q of the needle groove. The working needles complete the knitting motion guided by the guide surfaces. The connection between the control stitch 51 or 52 and the corresponding needle 31 or 52 is located in the front section 4q of the needle groove, which is not separated by the spacer. The rear side of this connection is located within the two needle tracks 41 or 42. During the knitting motion required by the control stitches 51 and 52, the needles always move within the undivided front section of the needle groove 4, and the control stitches mostly move within the needle tracks.

[0062] The structure of the selection mechanism of this embodiment and the function of the selection mechanism on the control pin are the same as those of the selection mechanism described in the third embodiment, and will not be described in detail. Example 6

[0063] like Figure 15 As shown, this embodiment is a needle plate and needle combination mechanism, which is also based on the needle plate mechanism in the above-mentioned embodiment 4, and has a structure basically the same as the needle plate and needle combination mechanism described in the embodiment 5. The difference is that: first, the knitting needles of this embodiment use the second knitting needles as described in the embodiment 2, that is, the knitting needles with unequal thickness structures, and the knitting needles 31 and 32 are provided with a thick portion adapted to 1 / 2 the width of the needle groove and a thin portion not greater than the width of the needle track, see Figure 7 Secondly, the length of the front section of the needle groove is comparable to the length of the knitting needle. When the control pins 51 and 52 drive the knitting needles 31 and 32 to extend forward in the needle groove, the knitting needles 31 and 32 are completely in the front section of the needle groove. When the knitting needles 31 and 32 are retracted, the thin parts of the knitting needles 31 and 32 are in the needle track 41 or 42. The knitting needles 31 and 32 are completely in the front section of the needle groove and the needle track. At this time, the control pins 51 and 52 are completely in the corresponding needle track. Example 7

[0064] This embodiment is a needle plate mechanism, such as Figure 16As shown, the needle plate mechanism includes a needle plate 8 respectively arranged on the front and rear needle beds of the flat knitting machine, a number of steel sheets 1 vertically arranged on the needle plate 8, a number of needle grooves 4 formed by adjacent steel sheets 1, and a number of spacers.

[0065] The spacer 2 used in this embodiment is the second spacer. The length of the second spacer 2 is the same as that of the steel sheet 1. A notch 21 is provided at the lower portion of the front section, so that the second spacer 2 has an unequal length structure in the longitudinal direction. Figure 17 The second spacer 2 is set in each needle groove 4 to separate the needle groove. The notch forms the undivided front section of the needle groove. The rear section of the second spacer on the rear side of the notch 21 forms the rear section of the needle groove at the corresponding needle groove position, and divides the rear section of the needle groove into two needle channels 41 and 42 arranged on the left and right. Example 8

[0066] like Figure 18-20 As shown, this embodiment is a needle plate and knitting needle combination mechanism, which is implemented on the needle plate mechanism of the above-mentioned embodiment seven, and also includes two knitting needles 31 and 32 arranged in each needle groove 4 and arranged on the left and right, and control pins 51 and 52 respectively connected to the rear of the two knitting needles 31 and 32, as well as a selection mechanism.

[0067] The two knitting needles 31 and 32 are third knitting needles, and a groove 3043 is provided on the inner or outer surface of the needle body of the third knitting needle, which is recessed into the side surface of the needle body and forms a convex portion with the side surface of the needle body as the top surface. The groove depth s is adapted to 1 / 2 the thickness of the second spacer. Figure 21 , the groove 3043 can be set on the needle body of the thick part of the second knitted unequal thickness structure, such as Figure 22 And the EE sectional view in the figure, it can also be set on the needle body of the first knitted equal thickness structure, such as Figure 23 In this embodiment, the grooves 3043 on the two third knitting needles are both located at the upper part of the needle body, thereby forming a protrusion below the groove. The two protrusions are respectively embedded in the notch 21 of the spacer, and the top surface of the protrusion, i.e., the side surface of the needle body, fits in the notch. Figure 21 .

[0068] The length of the notch 21 can be smaller than the length of the knitting needles 31 and 32, and a third knitting needle with a groove 3043 designed on the needle body based on the unequal thickness structure of the second knitting is used.

[0069] The length of the notch 21 can be greater than the length of the knitting needles 31 and 32, and a third knitting needle with a groove 3043 designed on the needle body of the uniform thickness structure of the first knitting is used. Embodiment 9
