Detailed ways

The detailed description and technical content of the present invention are described as follows with reference to the drawings:

1 and 9, the present invention provides a flat knitting machine structure 100, the flat knitting machine structure 100 can change the size of a mouth 10 according to weaving requirements during the weaving process, and then a three-dimensional fabric 90 (Spacer Fabric , also known as spacer fabric), the thickness of the three-dimensional fabric 90 is changed during the weaving process. The flat knitting machine structure 100 includes two needle beds 11 , 12 and two horn systems 13 or 14 respectively disposed facing one of the needle beds 11 or 12 . Among them, the two needle beds 11 and 12 are the front and rear needle beds referred to in the industry today. The two needle beds 11 and 12 are respectively arranged at an inclination angle, and the two needle beds 11 and 12 are arranged at intervals between them. A gap is formed between. Each needle bed 11 has a plurality of knitting needles 15 and a plurality of detent plates 16 respectively corresponding to one of the knitting needles 15. These detent plates 16 in the present invention are not Schenker plates, although these detent plates 16 are designed as Movable, but these sky teeth 16 do not move when one of the correspondingly arranged knitting needles 15 moves. Moreover, the mouthpiece 10 of the present invention is defined by the two needle beds 11 , 12 facing these cams 16 , and the distance between the mouthpieces 10 is equal to the distance between the two facing cambers 16 . (as indicated by 101 in the figure). Referring to FIGS. 3 to 6 again, each knitting needle 15 has a butt 151 , and each tooth piece 16 has a control butt 161 disposed on the same side as each of the butts 151 . Further, in the present invention, each of the tooth pieces 16 is respectively stacked on one of the correspondingly arranged knitting needles 15 , and the needle butt 151 is arranged on the side of the knitting needle 15 away from a needle bed base 17 . The control butt 161 is disposed on the side of the tooth piece 16 away from the needle bed base 17 . Referring to FIG. 6 , each knitting needle 15 of the present invention can define a knitting needle extension line 152 , the butt 151 on the knitting needle 15 is located on the knitting needle extension line 152 , and is provided corresponding to the knitting needle 15 The control butt 161 on the sky gear 16 is also located on the knitting needle extension line 152 . Furthermore, in order for the control butt 161 and the needle butt 151 to be located on the same knitting needle extension line 152 , the length of each tooth piece 16 is shorter than the total length of the knitting needle 15 .

4 and 6 again, in one embodiment, the tooth piece 16 has an extension section 162 formed with the control butt 161 , a bending section 163 connecting the extension section 162 , and connecting the bending section 163 and a loop segment 164 juxtaposed with the leading edge of one of the needles 15. Further, the extension section 162 is stacked above the knitting needle 15, and the bent section 163 makes the hanging loop section 164 and the extension section 162 located on different extension lines, so that the hanging loop section 164 can be The knitting needles 15 are juxtaposed so as to perform looping when the knitting needles 15 move. Furthermore, each of the sky teeth 16 further has a disengagement wire installation hole 165 located in the hanging ring section 164 and at least one limit wire installation hole 166 located in the extension section 164 . Please refer to FIG. 5 and FIG. 6 , in one embodiment, the sky tooth 16 is implemented with two different thicknesses on the hanging ring section 164 . Further, the thickness of the sky tooth 16 on the hanging ring section 164 can be used The thickness is smaller than that of other parts, as shown in Figure 6. 2 and 4 again, each needle bed 11 has a plurality of sliding grooves 171 respectively formed on the needle bed base 17, and each tooth piece 16 has a hanging ring section 164 and is placed on the sliding groove 171. A bottom 167 within the groove 171.

2, 7 and 8, on the other hand, each horn system 13 or 14 is disposed facing one of the needle beds 11 or 12, respectively, and each horn system 13 or 14 is provided with these needle butts A needle horn 131 for placement of 151 and a tooth horn 132 for placement of these control heels 161. Each knitting needle horn 131 and each of the tooth horns 132 may be composed of at least one horn unit, and the knitting needle horn 131 has a continuous mountain portion and a valley portion, so that the The needle butt 151 travels a knitting stroke 153 towards the mouth 10 when each of the horn systems 13 or 14 is in operation. Moreover, in one embodiment, each horn 132 has a first connecting section 134 , a straight section 135 connected to the first connecting section 134 and a second connecting section 135 connected to the straight section 135 Section 136 , the first connecting section 134 and the second connecting section 136 taper toward the direction of the straight section 135 respectively, and the size of the straight section 135 remains unchanged. Further, the first connecting section 134 and the second connecting section 136 are designed to be tapered, so that the control heels 161 can be reliably guided after the ridge angle 132 is displaced. Furthermore, each of the horns 132 is respectively disposed on the side of one of the horn systems 13 or 14 facing the mouth 10 .

On the other hand, the horn 132 of the present invention determines the position of each horn 16, thereby changing the size of the mouth 10, the horn 132 of the horn 132 is not like the knitting needle horn 131 which has obvious undulations. The part and the valley part, the part of the horn 132 used to guide each horn 16 is mostly straight, but the horn 132 of the present invention must be controlled to have a displacement stroke 133, During the displacement stroke 133, the horn 132 of the horn 132 performs a one-dimensional movement relative to a horn bearing 137, and drives each horn 16 to displace at the same time, changing the position of each horn 16, so that the mouth When the size of the mouth 10 is changed, the aforementioned displacement of the mountain angle 132 of the celestial tooth is as shown in FIG. 2 and FIG. 3 .

On the other hand, each horn 132 of the present invention can be further connected to a moving mechanism, and the moving mechanism can drive the horn 132 to travel the displacement stroke 133 according to a control signal received, and the generation of the control signal can is based on a programming setting. In this way, during the weaving process of the three-dimensional fabric 90 , the thickness of the three-dimensional fabric 90 can be changed, and even more, the three-dimensional fabric 90 can have a concave-convex structure outside the plane.
