TECHNICAL FIELD

[0001] The present application relates to the field of computerized flat knitting machines, in particular to a triangular knitting system with warp-weft mixed knitting function. BACKGROUND

[0002] A computerized flat knitting machine is a double needle bar latch needle weft knitting machine. Through the machine head and the triangular mechanism arranged on the triangular base plate of the machine head, i.e. the triangular system, the knitting needles arranged in the needle groove of the needle bed (needle plate) are driven to move up and down along the needle groove during the reciprocating movement of the machine head along the guide rail, and the knitting of the fabric is completed under the cooperation of the triangular mechanism and the pulling mechanism.

[0003] In the prior patent CN223304647U of the Cixing Company, it is attempted to add warp knitting function to the computerized flat knitting machine, i.e. on the basis of the original triangular system, a part of functional triangles are added so that certain warp knitting actions can be performed after weft knitting to add some warp knitting patterns.

[0004] However, according to the disclosed technical solution, it can only be used in the case of tight lifting eyes and tight knitting (tight lifting eyes and tight knitting refer to the situation that after passing through the middle mountain triangle, the knitting needles do not continue to descend along the density triangle, but continue to translate under the action of the pressure leg and directly enter the warp knitting triangle area), which means that a part of normal knitting function of the computerized flat knitting machine is abandoned in exchange for limited warp knitting function.

[0005] Based on the above problems, the present inventors have further researched and developed a triangular knitting system with warp-weft mixed knitting function, which can have a part of warp knitting function on the premise of retaining the original normal knitting function. SUMMARY

[0006] In order to achieve the above-mentioned purpose, the technical solution of the present application is as follows: A triangular knitting system with warp-weft mixed knitting function is arranged on a triangular base plate, which comprises a middle mountain triangle area for weft knitting, the side of the middle mountain triangle area is provided with a degree eye triangle, the side of the degree eye triangle is provided with a homing triangle and a needle pushing triangle, and the needle pushing triangle is arranged below the homing triangle; when the flat knitting machine needs to perform warp knitting after normal knitting, the first needle butt of the long needle passes through the knitting path of the middle mountain triangle area, first descends along the degree eye triangle, then rises through the needle pushing triangle, and then exits through the homing triangle; or when the flat knitting machine needs to perform warp knitting after tight knitting, the first needle butt of the long needle passes through the knitting path of the middle mountain triangle area, and then translates from the surface of the degree eye triangle to the homing triangle to exit; or when the flat knitting machine needs to perform warp knitting after tight lifting eyes, the first needle butt of the long needle passes through the lifting eye path of the middle mountain triangle area, and then translates from the surface of the degree eye triangle to the homing triangle to exit.

[0007] The middle triangle region is a main weft knitting region, which generally includes an upper middle triangle forming a normal knitting track, a lower middle triangle (the drop stitch knitting is that the needle butt of the long needle directly slides from the surface of the lower middle triangle without passing through the upper middle triangle), and a dish mountain triangle and a lifting needle triangle arranged below the lower middle triangle, and the degree triangle is also commonly called the density triangle in China; the above-mentioned triangles are commonly used triangles of the computerized flat knitting machine, which will not be described here. The existing computerized flat knitting machine generally adopts a three-system structure, that is, three weft knitting systems with consistent structures are arranged on one machine head, and the improved triangle system is arranged on the left side and the right side of the machine head (which cannot be used for the middle system), and when a double knitting system or a single knitting system is arranged on one machine head, the technical solution can also be arranged on both sides of the machine head.

[0008] The combination needle (also referred to as the whole combination needle) of the flat knitting machine generally includes a knitting needle with a needle hook, a long needle (the needle butt of which acts with the middle triangle region), a spring needle (the needle butt of which acts with the drop stitch pressing block, the needle cleaning triangle), and a selection needle (which acts with the selection needle).

[0009] In order to facilitate understanding, the triangle base plate is taken as a reference, and the movement of the knitting needle relative to the triangle base plate is described (in fact, the machine head drives the triangle base plate to move back and forth, and drives the knitting needle to move up and down on the needle bed).

[0010] In the above technical solution, in addition to the function of performing warp knitting after tight drop stitch and tight knitting as described in CN223304647U, the function of performing warp knitting after normal knitting is completed (that is, the normal knitting can be completed by descending along the degree triangle, and then the warp knitting is performed by ascending the pushing needle triangle) can also be realized.

[0011] Further, the homing triangle is provided with a one-way channel at the lower part, the entrance of the one-way channel is from the top of the pushing needle triangle, and the one-way channel and the bottom of the upper middle triangle are at the same horizontal height; when the warp knitting is performed after the normal knitting, the tight knitting and the tight drop stitch, the first needle butt of the long needle passes out through the one-way channel.

[0012] Further, the drop stitch pressing block is arranged below the middle triangle region, and the drop stitch pressing block is provided with an interface needle pressing block on each side; the drop stitch pressing block and the interface needle pressing block can be extended and retracted relative to the triangle base plate.

[0013] Further, when the flat knitting machine performs warp knitting after normal knitting, the needle butt of the spring needle translates above the drop stitch pressing block and the interface needle pressing block, and the two interface needle pressing blocks do not retract into the triangle base plate.

[0014] Further, when the flat knitting machine performs warp knitting after tight knitting, the needle butt of the spring needle translates above the two interface needle pressing blocks, and the drop stitch pressing block retracts into the triangle base plate.

[0015] Furthermore, when the flat knitting machine performs warp knitting after the tight hanging pattern, the needle heel of the spring needle moves horizontally across the surface of the hanging pattern pressure block, and the needle receiving pressure block on the side near the return triangle does not retract into the triangle base plate, while the needle receiving pressure block on the other side retracts into the triangle base plate.

[0016] Furthermore, after warp knitting is completed, when the knitting head drives the triangular base plate to run in the opposite direction, the first heel of the long needle passes through the bottom of the return triangle and presses the pusher triangle into the triangular base plate; at the same time, the pusher triangle has the function of actively retracting the triangular base plate.

[0017] To achieve the above function, the pusher triangle only needs to be made into an inclined slope on one side of the needle heel return position, and a reset spring is set inside its triangular base plate. In this way, when the needle heel is driven by the machine head to run in the reverse direction, the pusher triangle can be pressed into the triangular base plate without damaging the needle heel.

[0018] When normal knitting is being performed without warp knitting, the pusher cam is in a non-working retracted state. In the flat knitting machine, the active retraction of the cam into the cam base plate is generally controlled by an electromagnetic switch (i.e., a return spring achieves passive reset, and the electromagnetic switch determines whether the cam extends out of the cam base plate and is in a working state. This structure is described in detail in the applicant's prior application and will not be described here).

[0019] Furthermore, a guard triangle is set above the return triangle, and a guard triangle is set above the eyelet triangle. When the flat knitting machine performs warp knitting after normal knitting, the second heel of the long needle passes under the guard triangle. When the flat knitting machine performs warp knitting after tight weaving or tight hanging, the second heel of the long needle passes under the guard and guard triangle of the hanging.

[0020] The protective triangle plays a supporting and limiting role during warp knitting.

[0021] Furthermore, a protrusion is provided below the one-way channel, which limits and guides the first needle heel of the long needle when warp knitting is not being performed or the knitting head is moving in the opposite direction.

[0022] Furthermore, the triangular weaving system is located on both sides of the flat knitting machine head.

[0023] This technical feature is explained in the preceding text.

[0024] By adopting the above solution, the present invention has the following advantages compared with the prior art: The main function of the computerized flat knitting machine is achieved by using the combination of the push-back triangle and the return triangle. This allows the machine to perform warp knitting after normal knitting, tight stitching, or tight knitting. While ensuring the original functions of the computerized flat knitting machine, it also enables warp knitting on the machine. Attached Figure Description

[0027] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0028] A typical computerized flat knitting machine has a three-system structure. This embodiment will be described using the triangular system located on the right side of the three systems as an example (which is symmetrical to the system on the left side).

[0029] like Figure 1As shown, a triangular knitting system with warp and weft mixed knitting function is set on a triangular base plate. It includes a knitting triangular area located at the upper part of the triangular base plate and a needle selection triangular area located at the lower part. Correspondingly, the combination needles of the flat knitting machine include knitting needles 1, long needles 2, spring needles 3, and needle selection 4 from top to bottom. The needle selection triangular area includes a needle selector 17 and various needle selection triangles 18. Corresponding to this are the needle selection 4 in the combination needles. The needle selection includes multiple needle heels for linkage with the needle selector and various needle selection triangles. This area is not the focus of this invention and will not be described in detail here.

[0030] The knitting triangle area includes the upper middle mountain triangle 11 and the lower middle mountain triangle 12 located in the middle, and the left-hand angled triangle 802 and the right-hand angled triangle 801 located on both sides of the upper middle mountain triangle 11, the left-starting triangle 13 and the right-starting triangle located on both sides of the lower middle mountain triangle 12, the hanging eyelet block 15 located below the lower middle mountain triangle 12, and the left-connecting needle block 141 and the right-connecting needle block 142 located on both sides of the hanging eyelet block 15. When the triangle system also has a turning needle function, a turning needle triangle 10 and a pointed mountain triangle are also set above the upper middle mountain triangle 11. On both sides of the turning needle triangle 10 and above the corresponding angled triangles, there are left-hand angled guards 901 and right-hand angled guards 902. On the right side of the right-hand angled guard 902, there is a guard triangle 7, and a return triangle 6 located below the guard triangle 7. The return triangle 6 is immediately below the push needle triangle 5, and the push needle triangle 5 is below the clearing needle triangle 16.

[0031] The combination needles corresponding to the knitting triangle area are long needles 2 and spring needles 3. The needle heel 301 of the spring needle can be linked with the hanging eyelet block 15, the left connecting needle block 141, the right connecting needle block 142, and the clearing needle triangle.

[0032] The second heel 202 of the long needle corresponds to the left eye guard 901, the right eye guard 902, and the guard triangle 7 (because this embodiment does not involve turning the needle and shifting the circle, the turning needle triangle 10 can be in the state of retracting the triangle base plate, so the turning needle triangle 10, etc. will not be described in detail); the first heel 201 of the long needle can be linked with the left starting needle triangle 13, the left eye triangle 802, the upper middle mountain triangle 11, the lower middle mountain triangle 12, the right eye triangle 801, the push needle triangle 5, and the return triangle 6 (because this embodiment is a right triangle system, the right starting needle triangle is not involved).

[0033] The bottom edge of the guard triangle 7 is relatively straight. A one-way channel 601 is provided at the lower part of the return triangle 6. The entrance of the one-way channel 601 is inclined relative to the top of the pusher triangle 5 (from the base of the triangle to the surface of the return triangle 6). Below the one-way channel 601 is a downward protrusion for use when warp knitting or reverse needle movement is not performed. In this embodiment, the pusher triangle 5 has a slanted structure on the left side, which needs to be able to connect to the first needle heel 201 emerging from the right needle triangle 801. The right side has a slanted structure, which needs to work with the aforementioned protrusion of the return triangle 6 to press the pusher triangle 5 into the base of the triangle when the first needle heel 201 moves back from right to left.

[0034] Based on the aforementioned structure, the different weaving methods are explained as follows ( Figures 2-4 (Taking the example of the knitting needles moving from left to right relative to the triangular base plate) like Figure 2 As shown, when preparing to perform warp knitting after normal knitting: The needle selection triangle on the left side of the needle selection area is in working condition, lifting the bottom needle heel of the needle selection, so that the needle heel of the spring needle slides over the left end of the left needle receiving block 141, the hanging eye block 15, and the right needle receiving block 142 without being linked to them.

[0035] Correspondingly, the first heel 201 of the long needle begins from the starting triangle on the left, enters the normal knitting track between the upper middle triangle 11 and the lower middle triangle 12, and then descends through the right-hand measuring triangle. At this point, the needle completes the normal knitting process of rising, hooking yarn, and then descending at the needle bed opening. Afterward, the first heel 201 continues to move to the right, moves upward along the left side of the pusher triangle 5, hooks yarn in coordination with the warp yarn feeder, and exits through the one-way channel 601 of the return triangle 6. The second heel 202 of the long needle follows the trajectory of the first heel 201, passing under the upper measuring guard and guard triangle 7.

[0036] like Figure 3 As shown, when preparing to perform warp knitting after tight weaving: The needle selection triangle in the needle selection area is in the retracted triangle state, while the left needle receiving block 141 and the right needle receiving block 142 are in the working state, and the hanging eye block 15 is in the non-working retracted state, so that the needle heel of the spring needle slides over the surface of the left needle receiving block 141 and the right needle receiving block 142, but is not affected by the hanging eye block 15.

[0037] Correspondingly, the first heel 201 of the long needle starts from the starting triangle on the left, enters the knitting track between the upper middle triangle 11 and the lower middle triangle 12, and then moves across the surface of the right angle triangle 801 (at this time, due to the action of the right connecting needle block 142, the first heel 201 is in a "semi-floating" state and can pass through the surface of the right angle triangle 801), and directly enters the one-way channel 601 of the return triangle 6; the second heel 202 of the long needle also follows the trajectory of the first heel 201.

[0038] like Figure 4 As shown, when preparing to perform warp knitting after the initial stitching: The needle selection triangle in the needle selection area is in the retracted triangle state, while the left needle receiving block 141 is in the retracted non-working state, and the eyelet block 15 and the right needle receiving block 142 are in the working state. The needle heel of the spring needle slides over the surface of the eyelet block 15 and the right needle receiving block 142.

[0039] Correspondingly, the first heel 201 of the long needle starts from the starting triangle on the left. Due to the action of the hanging eye block 15, it no longer enters the knitting track between the upper middle mountain triangle 11 and the lower middle mountain triangle 12, but slides directly across the surface of the lower middle mountain triangle 12 and directly enters the one-way channel 601 of the return triangle 6; the second heel 202 of the long needle also follows the trajectory of the first heel 201.

[0040] like Figure 5 As shown, during normal weaving without warp knitting: Set the pusher triangle 5 to the non-working state, and actively retract it into the triangle base plate. The path of each needle heel is aligned with... Figure 2 The result is consistent with the previous result, except that when the first heel 201 of the long needle reaches the push triangle 5, it no longer rises to the return triangle 6.

[0041] like Figure 6 As shown, after the knitting is completed, when the knitting head drives the cam to move in the opposite direction (equivalent to the knitting needles moving from right to left): The main point is that the first heel of the long stitch, 201, descends under the influence of the protrusion of the return triangle 6, and its subsequent trajectory is similar to... Figure 7 The trajectory shown is consistent with the reverse movement after normal weaving.

[0042] The pusher triangle 5 is in a non-working state when knitting normally and not warp knitting. However, when warp knitting is in progress, the first stitch heel 201 that returns can press the pusher triangle 5 into the triangle base plate through the inclined surface on the right side of the pusher triangle 5.

[0043] The above are merely specific embodiments of the present invention. Furthermore, terms such as "upper," "lower," "left," "right," and "middle" used in the present invention are for reference only and are not absolute limitations. Any non-substantial modifications made using the present invention shall be considered as infringing upon the protection scope of the present invention.
