Detailed Description
The present invention is described in detail and technical content with reference to the accompanying drawings, wherein:
referring to fig. 1 and 9, the present invention provides a flat knitting machine structure 100, in which the size of a nozzle 10 can be changed according to the weaving requirement during the weaving process of the flat knitting machine structure 100, so as to change the thickness of a three-dimensional Fabric 90(Spacer Fabric) during the weaving process of the three-dimensional Fabric 90. The flat knitting machine structure 100 includes two needle beds 11, 12 and two cam systems 13 or 14 disposed facing one of the needle beds 11 or 12, respectively. Wherein, the two needle beds 11, 12 are the front needle bed and the back needle bed in the present industry, the two needle beds 11, 12 are respectively disposed at an inclined angle, and the two needle beds 11, 12 are disposed at intervals to form a gap therebetween. Each needle bed 11 has a plurality of knitting needles 15 and a plurality of top plates 16 respectively corresponding to one knitting needle 15, the top plates 16 are non-sinkers, the top plates 16 are designed to be movable, but the top plates 16 do not move when one knitting needle 15 corresponding to the one knitting needle 15 is moved. Moreover, the mouth 10 of the invention is delimited by the facing crown pieces 16 of the two needle beds 11, 12, the distance of the mouth 10 being equal to the distance between the facing crown pieces 16 (indicated by 101 in the figure). Referring to fig. 3 to 6, each knitting needle 15 has a butt 151, and each pick 16 has a control butt 161 disposed on the same side as each butt 151. Furthermore, the present invention makes each of the pick 16 overlap with one of the knitting needles 15 correspondingly, the butt 151 is disposed on a side of the knitting needle 15 away from a needle bed seat 17, and the control butt 161 is disposed on a side of the pick 16 away from the needle bed seat 17. Referring to fig. 6, each of the knitting needles 15 of the present invention defines a needle extension 152, the butt 151 of the knitting needle 15 is located on the needle extension 152, and the control butt 161 of the crown gear 16 corresponding to the knitting needle 15 is also located on the needle extension 152. Furthermore, in order to make the control butt 161 and the needle butt 151 located on the same needle extension 152, the length of each of the crown gear pieces 16 is shorter than the total length of the knitting needle 15.
Referring to fig. 4 and 6, in one embodiment, the crown plate 16 has an extension 162 formed with the control heel 161, a bending section 163 connected to the extension 162, and a hooking ring section 164 connected to the bending section 163 and juxtaposed to the front edge of one of the knitting needles 15. Furthermore, the extension 162 is overlapped above the knitting needle 15, and the bending section 163 makes the hanging ring section 164 and the extension 162 located on different extension lines, and makes the hanging ring section 164 parallel to the knitting needle 15 for hanging ring when the knitting needle 15 is operated. Furthermore, each of the plurality of antenna blades 16 further has a knock-out wire mounting hole 165 located in the hanging ring section 164 and at least one restraining wire mounting hole 166 located in the extending section 164. Referring to fig. 5 and 6, in one embodiment, the crown plate 16 is implemented in the suspension ring section 164 with two different thicknesses, and further, the thickness of the crown plate 16 in the suspension ring section 164 can be implemented with a smaller thickness than other portions, as shown in fig. 6. Referring to fig. 2 and 4, each needle bed 11 has a plurality of sliding slots 171 respectively formed on the needle bed base 17, and each top plate 16 has a bottom 167 located on the suspension loop section 164 and disposed in the sliding slot 171.
Referring to fig. 2, 7 and 8, on the other hand, each cam system 13 or 14 is disposed facing one of the needle beds 11 or 12, and each cam system 13 or 14 has a knitting needle cam 131 for receiving the needle butts 151 and a one-day tooth cam 132 for receiving the control butts 161. Each needle cam 131 and each of the top plate cams 132 may be formed of at least one cam unit, and the needle cam 131 has a continuous cam portion and a continuous valley portion, so that the butt 151 disposed therein advances a knitting stroke 153 toward the nozzle 10 when each cam system 13 or 14 operates. Moreover, in an embodiment, each of the top tooth plate corners 132 has a first connecting section 134, a straight section 135 connected to the first connecting section 134, and a second connecting section 136 connected to the straight section 135, wherein the first connecting section 134 and the second connecting section 136 respectively taper toward the straight section 135, and the size of the straight section 135 is not changed. Further, the first and second lead segments 134, 136 are tapered in order to securely guide the control heels 161 after the displacement of the zenith tooth angle 132. Furthermore, each of the roof tooth piece angles 132 is disposed on one of the angle systems 13 or 14 facing the nozzle 10.
In summary, the Tianqi piece peak 132 of the present invention determines the position of each Tianqi piece 16, and thus changes the size of the nozzle 10, the Tianqi piece peak 132 does not have the peak portion and the valley portion with obvious fluctuation like the knitting needle peak 131, the Tianqi piece peak 132 is used to guide the position of each Tianqi piece 16 to be mostly straight, but the Tianqi piece peak 132 of the present invention is controlled to have a displacement stroke 133, in the displacement stroke 133, the Tianqi piece peak 132 performs a one-dimensional motion relative to a peak bearing 137, and simultaneously drives each Tianqi piece 16 to displace, so as to change the position of each Tianqi piece 16, and change the size of the nozzle 10, and the displacement of the Tianqi piece peak 132 is as shown in fig. 2 and 3.
In summary, each of the Tianchi blade mountain angles 132 of the present invention may further be connected to a moving mechanism, the moving mechanism may drive the Tianchi blade mountain angle 132 to move the displacement stroke 133 according to a received control signal, and the generation of the control signal may be set based on a program. Therefore, in the process of weaving the three-dimensional fabric 90, the thickness of the three-dimensional fabric 90 is changed, and further, the three-dimensional fabric 90 can generate an out-of-plane concave-convex structure.
