[0044] When implementing it, Figures 1 to 3 As shown, a main mesh 20 and an auxiliary mesh 30 are provided on one side of the triangular base plate 10, and a buffer component is provided on the auxiliary mesh 30 to prevent the knitting thread from breaking when the auxiliary mesh 30 collides with the needle.

[0045] A mesh motor 40 for changing the position of the main mesh 20 and the auxiliary mesh 30 is provided on the other side of the triangle base plate 10. A switching electromagnet 50 for driving the knitting triangle 21 and the transfer triangle 31 is provided between the mesh motor 40. The switching electromagnet 50 drives the switching of the knitting triangle 21 and the transfer triangle 31 to switch the knitting mode, and cooperates with the main mesh 20 and the auxiliary mesh 30 to realize multi-stage density knitting in the same row of knitting process. Specifically, the main mesh 20 and the auxiliary mesh 30 each correspond to a density of knitting for the knitted fabric during knitting.

[0046] Specifically, Figures 1 to 3 As shown, the triangular base plate 10 is provided with a slide groove for the movement of the main degree 20 and the auxiliary degree 30. The main degree 20 is connected to the main degree control block. The main degree 20 is located on one side of the triangular base plate 10, and the main degree control block is located on the other side of the triangular base plate 10; the auxiliary degree 30 is connected to the auxiliary degree control block 32. The auxiliary degree 30 is located on one side of the triangular base plate 10, and the auxiliary degree control block 32 is located on the other side of the triangular base plate 10. The auxiliary degree 30 is located above the main degree 20.

[0047] like Figures 4 to 6 As shown, the drawings of this embodiment take the auxiliary mesh control block 32 as an example. The main mesh control block and the auxiliary mesh control block 32 are respectively connected to the mesh rack 41 through the mesh bearing 35. The output end of the mesh motor 40 is provided with a mesh gear 42, and the mesh rack 41 is meshed with the mesh gear 42. The mesh motor 40 drives the mesh gear 42 to rotate, and the mesh gear 42 rotates to drive the mesh rack 41 to move; the main mesh control block and the auxiliary mesh control block 32 have the same working principle. The main mesh control block is not shown in the drawings. The main mesh control block is provided with a mesh bearing groove for sliding the mesh bearing 35.

The main mesh control block drives the main mesh 20 to move in the slide groove on the triangular base plate 10 as the mesh bearing 35 slides.

Specifically, the auxiliary mesh control block 32 is detachably or / and movably connected to the push block 33, and the push block 33 can rotate on the auxiliary mesh control block 32. A boss 34 is provided on the side where the auxiliary mesh control block 32 is connected to the push block 33, and a mesh bearing groove for sliding a mesh bearing 35 is provided between the boss 34 and the push block 33. The movement of the mesh rack 41 drives the mesh bearing 35 on the auxiliary mesh control block 32 to slide in the mesh bearing groove, and the auxiliary mesh control block 32 drives the auxiliary mesh 30 to slide in the slide groove on the triangular base plate 10 as the mesh bearing 35 slides.

[0049] Specifically, Figures 4 to 6 As shown, the auxiliary mesh control block 32 is provided with a first groove, the push block 33 is provided with a second groove, and compression springs 36 are provided in the first groove and the second groove. When the auxiliary mesh 30 collides with the needle, the push block 33 does not collide with the needle. Due to the effect of inertia, the push block 33 rotates relative to the auxiliary mesh control block 32, thereby compressing the compression spring 36 located between the auxiliary mesh control block 32 and the push block 33. After the compression spring 36 is compressed, an elastic force is generated, which acts on the auxiliary mesh control block 32 and the push block 33, and then acts on the auxiliary mesh 30, so that the auxiliary mesh 30 can buffer the collision with the needle, thereby avoiding the breakage of the knitted thread when the auxiliary mesh 30 hits the needle.

[0050] Preferably, if Figures 1 to 3 As shown, the mesh motor 40 includes a main mesh motor 43 for driving the main mesh 20 to move and an auxiliary mesh motor 44 for driving the auxiliary mesh 30 to move. The main mesh motor 43 and the auxiliary mesh motor 44 are alternately arranged on the triangle bottom plate 10 in a step-by-step manner, and the auxiliary mesh motor 44 is located above the main mesh motor 43.

The switching of the weaving triangle 21 and the turning needle triangle 31 is used to switch the weaving mode, cooperate with the main mesh 20 or the auxiliary mesh 30 to slide on the triangle base plate 10, change the bending depth of the knitting needle, control the coil size, adjust and change the knitting density, and realize one row of weaving and multi-segment density weaving.

[0052] Preferably, if Figure 1 , Figure 3 , Figure 8 As shown, the triangular base plate 10 is further provided with a plurality of needle selectors 60, which are located below the main mesh 20 and the auxiliary mesh 30, and between the needle selectors 60 there are laterally provided workstation electromagnets 72 for driving the state switching of the needle receiving presser leg 70 and the loop collecting presser leg 71, the workstation electromagnets 72 are arranged on the triangular base plate 10 through magnet fixing seats 73, and the workstation electromagnets 72 are arranged parallel to the triangular base plate 10.

[0053] Specifically, Figures 8 to 10 As shown, the needle press leg 70 and the ring press leg 71 are arranged side by side on the press leg seat 75 through a rotating pin 74, and the press leg seat 75 is connected to the magnet fixing seat 73, and the connection method can be a fixed connection; the needle press leg 70 and the ring press leg 71 are sleeved on the rotating pin 74 through a torsion spring 76.

[0054] Preferably, if Figures 8 to 10 As shown, in this embodiment, the number of needle press legs 70 is two, the number of loop press legs 71 is one, the loop press leg 71 is located between the two needle press legs 70, the number of work station electromagnets 72 matches the number of needle press legs 70 and the loop press legs 71, the output ends of the work station electromagnets 72 are respectively connected to one end of the needle press legs 70 or the loop press legs 71, each work station electromagnet 72 respectively drives the needle press leg 70 or the loop press leg 71 to rotate on the rotating pin 74 through the torsion spring 76, the rotation of the needle press leg 70 and the loop press leg 71 cooperates with the main mesh 20 or the auxiliary mesh 30 to move on the triangle base plate 10 for knitting.

[0055] Preferably, if Fig.11 As shown, a push-pin assembly is provided on the triangular base plate 10, and the push-pin assembly is located below the needle selector 60. The push-pin assembly includes a needle selection reset triangle 80 and a sensor 81 for sensing the position of a push-pin slide plate 82. Specifically, the needle selection reset triangle 80 is arranged on the triangular base plate 10 through a push-pin triangle seat. The push-pin triangle seat is provided with a push-pin bearing for relative movement with the push-pin slide plate 82. The push-pin slide plate 82 is provided with a switching groove for sliding of the push-pin bearing 83 and a groove for sensing the position of the sensor 81. The switching groove is a thickened Z-shape. The push-pin bearing 83 slides in the switching groove to drive the push-pin triangle to switch the state, so that the needle selector 60 resets the needle selection.

[0056] Preferably, the sensor 81 is connected to the mainboard of the computer flat knitting machine. In the present embodiment, the sensor 81 may be a magnetic sensor. When the position of the switching slide 82 moves abnormally, the sensor 81 senses the position of the switching slide 821 and sends a signal to the mainboard of the computer flat knitting machine, and issues an abnormal alarm or warning in time to reduce the production of defective products.

[0057] The structures and working principles of the knitting cam, the transfer cam, the needle selector, the needle receiving presser leg and the tuck presser leg are existing mature technologies and will not be described in detail here.

[0058] The present invention provides a flat knitting machine mountain plate capable of knitting in multiple density sections. When the knitting density is actually adjusted, the switching electromagnet 50 drives the needle transfer lever 51 to rotate around its midpoint or fulcrum, driving the knitting guide rod 52 or the needle transfer guide rod 53 to move forward and backward. When the knitting cam 21 moves forward with the knitting guide rod 52, the main mesh motor 43 cooperates with the mesh gear 42 to rotate and drive the mesh rack 41 to move. The mesh bearing 35 on the mesh rack 41 slides on the mesh bearing groove of the main mesh control block, driving the main mesh 20 to slide on the cam bottom plate 10, knitting is performed, and a knitting density is achieved.

[0059] When the transfer cam 31 moves forward with the transfer guide rod 53, it cooperates with the auxiliary mesh motor 44 to drive the mesh gear 42 to rotate and drive the mesh rack 41 to move, and the mesh bearing 35 on the mesh rack 41 slides in the mesh bearing groove between the auxiliary mesh control block 32 and the push block 33, driving the auxiliary mesh 30 to slide on the cam bottom plate 10 to perform knitting and achieve another knitting density;

[0060] The switching electromagnet 50 drives the knitting cam 21 and the transfer cam 31 to switch the knitting mode, and cooperates with the main mesh 20 and the auxiliary mesh 30 to perform multi-density knitting in the same row of knitting.

[0061] At the same time, the work station electromagnet 72 drives the needle press leg 70 or the loop press leg 71 to rotate on the rotating pin 74 through the torsion spring 76. The rotation of the needle press leg 70 and the loop press leg 71 cooperates with the main mesh 20 or the auxiliary mesh 30 to move on the triangular base plate 10 for knitting.

[0062] When the auxiliary mesh collides with the needle, the push block 33 rotates relative to the auxiliary mesh control block 32 due to the effect of inertia, thereby compressing the compression spring 36 located between the auxiliary mesh control block 32 and the push block 33. After being compressed, the compression spring 36 generates elastic force, which acts on the auxiliary mesh control block 32 and the push block 33, and then acts on the auxiliary mesh 30, so that the auxiliary mesh 30 can buffer the collision with the needle, thereby avoiding the breakage of the knitted thread when the auxiliary mesh 30 collides with the needle.

[0063] When the needle selection reset triangle 80 is in an abnormal state, the sensor 81 senses the position of the switching slide 82 and sends a signal to the computer flat knitting machine mainboard, issuing an abnormal alarm or early warning in time to facilitate maintenance so that the needle selector can be reset normally.

[0064] Compared with the prior art, the present invention provides a flat knitting machine mountain plate capable of weaving in multiple density sections, and a secondary mesh buffer component is arranged on the secondary mesh to avoid the problem of the knitting thread breaking when the secondary mesh collides with the needle and affecting the production efficiency. The knitting triangle and the needle transfer triangle are switched by switching electromagnets to switch the knitting mode, and the main mesh and the secondary mesh are coordinated to achieve multiple density weaving in the same row of knitting. The present invention provides a flat knitting machine mountain plate capable of weaving in multiple density sections, which can not only achieve multiple density weaving in the same row of knitting, but also improve the production efficiency and reduce the production cost caused by motor damage.

These terms are used only to more conveniently describe and explain the essence of the present invention; interpreting them as any additional limitation is contrary to the spirit of the present invention.
