Description

Technical Field

[0001] The utility model belongs to the technical field of machinery, and relates to a combined sinker for a flat knitting machine, in particular to a normally closed sinker for a flat knitting machine. Background Technique

[0002] A sinker is a fitting for textile machinery and plays a role in pulling the coils on a flat knitting machine. The sinkers are arranged beside each knitting needle and can well control the old coils and new yarns on each knitting needle, which is beneficial to knitting three-dimensional fabrics with three-dimensional effects and is also convenient for fully-fashioned knitting such as opening bags and knitting door guards.

[0003] The sinkers are installed on the needle plate along with the knitting needles and are controlled by the triangular tracks on the machine head. The triangles make the sinkers move forward, press the fabric when the knitting needles rise to assist in loop withdrawal; or retreat when the knitting needles descend to prepare for loop doffing. The settings of the sinkers are generally divided into normally open or normally closed. The normally open sinkers press down the coils during knitting by the machine head and are in a disengaged state at other times, and are generally used in flat knitting machines with a bottom plate and can provide enough clearance in cooperation with the rising of the bottom plate; the normally closed sinkers are disengaged during knitting by the machine head, press down the coils after knitting is completed, and are also in a pressed state at other times, continuously applying pressure to the knitted fabric piece, and are generally applicable to equipment with low or no pulling force.

[0004] Most of the existing sinkers adopt a normally open structure and are almost all of one-piece setting. When in use, the position of the sinker after pressing down is usually at the connection between two coils. At this time, the acting force applied to the coils is relatively small. When the triangle drives the knitting needle to protrude for knitting, the old coil is easily driven by the knitting needle, which is not conducive to the knitting needle hooking the new yarn for loop formation; if the acting force applied by the sinker to the coils is increased, the coil is easily broken, and the use effect is not ideal.

[0005] To sum up, in order to solve the deficiencies in the structure of the existing sinkers for flat knitting machines, the utility model designs a combined sinker for a flat knitting machine with reasonable structure and good use effect. Summary of the Invention

[0006] The utility model provides a combined sinker for a flat knitting machine with reasonable structure and good use effect to solve the problems existing in the prior art.

[0007] The purpose of the utility model can be achieved by the following technical solutions: A combined sinker for a flat knitting machine, comprising:

[0008] A body installed at the front end of the needle plate of the flat knitting machine. The body is composed of a main piece and a sub-piece that are mutually attached. On the corresponding sides of the main piece and the sub-piece, they are respectively bent and extended to enclose a needle-passing channel;

[0009] Knitting needles are arranged on the needle plate. The above-mentioned body is installed between two adjacent knitting needles, and each knitting needle can pass through the needle-passing channel on the corresponding body when knitting the fabric.

[0010] A rotating shaft is arranged through the bottom of the main piece. The main piece drives the auxiliary piece to rotate around the rotating shaft to a specified position. When the coil on the fabric moves to this specified position along with the knitting needle, the main piece and the auxiliary piece are buckled on both sides of the corresponding coil.

[0011] As a further improvement of this case, the main piece includes a first base piece, and a first pressing piece extends outward from the first base piece. The auxiliary piece includes a second base piece, and a second pressing piece corresponding to the first pressing piece extends outward from the second base piece. The two pressing pieces enclose the above-mentioned needle-passing channel, and the ends of the two pressing pieces are buckled on both sides of the coil.

[0012] As a further improvement of this case, the first base piece is bent and transitioned to the first pressing piece, and the second base piece is bent and transitioned to the second pressing piece after being bent twice continuously.

[0013] As a further improvement of this case, the bending angle of the second pressing piece is greater than that of the first pressing piece, and the ends of the two pressing pieces are partially crossed.

[0014] As a further improvement of this case, a first notch is provided at the bottom of the first pressing piece, and a second notch is provided at the top of the second pressing piece. The first notch is located above the second notch.

[0015] As a further improvement of this case, reinforcing ribs are respectively fixed on the opposite sides of the two pressing pieces, and the reinforcing ribs extend along the corresponding pressing pieces in a curved manner.

[0016] As a further improvement of this case, two first positioning holes are provided on the first base piece, two second positioning holes corresponding to the two first positioning holes are provided on the second base piece, and an installation hole for the rotating shaft to pass through is further provided at the bottom of the first base piece.

[0017] Compared with the prior art, the structure of the present utility model is reasonably arranged. Through the combination of the main piece and the auxiliary piece, the main piece and the auxiliary piece respectively buckle the two sides of the corresponding coil, enhancing the control degree of the coil, ensuring the overall buckling of the sinker on the coil, and avoiding the coil moving along with the knitting needle when the knitting needle exits the needle, so that the coil cannot form a loop again; at the same time, a needle-passing channel is formed by the enclosure between the main piece and the auxiliary piece, providing space for the normal needle exit and needle return of the knitting needle, and avoiding the influence of the sinker structure on the needle plate structure of the computerized flat knitting machine.

Detailed implementation manners

[0025] Next, in combination with the embodiments and the drawings, the technical solutions of the present utility model will be further described.

[0026] As Figure 1 and Figure 2 shown, the combined computer flat knitting machine sinker of the present utility model includes:

[0027] A body 30, which is installed at the front end of the needle plate of the computer flat knitting machine. The body 30 is composed of a main piece 10 and a sub-piece 20 that are arranged in a mutually attached manner. On the corresponding sides of the main piece 10 and the sub-piece 20, they respectively bend and extend and enclose to form a needle-passing channel 42;

[0028] Knitting needles 41, which are arranged on the needle plate. The above-mentioned body 30 is installed between two adjacent knitting needles 41, and each knitting needle 41 can pass through the needle-passing channel 42 on the corresponding body 30 when knitting the fabric;

[0029] A rotating shaft 43, which is penetrated at the bottom of the main piece 10. The main piece 10 drives the sub-piece 20 to rotate around the rotating shaft 43 to a specified position. When the coil 50 on the fabric moves to this specified position along with the knitting needle 41, the main piece 10 and the sub-piece 20 are buckled on both sides of the corresponding coil 50.

[0030] Most of the existing sinkers adopt an open structure and are almost all one-piece. During use, the position of the sinker after being pressed down is usually at the connection between two coils. At this time, the force applied to the coil is relatively small. When the cam drives the knitting needle to protrude for knitting, the old coil is easily driven by the knitting needle, which is not conducive to the knitting needle hooking the new yarn to form a loop. If the force applied by the sinker to the coil is increased, the coil is easily broken. Therefore, the existing sinker structure has an unsatisfactory use effect.

[0031] For this reason, the present utility model provides a combined computer flat knitting machine sinker, especially a normally closed sinker. In the form of the combination of the main piece 10 and the auxiliary piece 20, the main piece 10 and the auxiliary piece 20 respectively fasten the two sides of the corresponding coil 50, enhancing the control degree of the coil 50 and ensuring the overall buckling of the sinker on the coil 50, so as to prevent the coil 50 from moving along with the knitting needle 41 when the knitting needle 41 protrudes and being unable to form a loop again. At the same time, a needle passing channel 42 is formed by the enclosure between the main piece 10 and the auxiliary piece 20, providing space for the normal protrusion and retraction of the knitting needle 41, and preventing the sinker structure from affecting the needle bed structure of the computer flat knitting machine.

[0032] The sinkers are actually arranged on the needle bed together with the knitting needles 41. Each knitting needle 41 is equipped with a sinker. The sinkers and the knitting needles 41 are arranged at intervals. Each sinker is coaxially arranged and connected by a rotating shaft 43.

[0033] During operation, the cams on the computer flat knitting machine drive each sinker to rotate a certain angle around the rotating shaft 43, and the sinker reaches the designated position. When the knitting needle 41 protrudes, the coil 50 on the knitting needle 41 will move a small distance accordingly. When the coil 50 reaches the position of the sinker, it is held by the main piece 10 and the auxiliary piece 20 and will no longer move up with the knitting needle 41, thereby realizing the buckling of the sinker body 30 (the main piece 10 and the auxiliary piece 20) on the coil 50 and ensuring that the coil 50 is completely buckled.

[0034] Specifically, in view of the relatively compact structure of the needle bed of the computer flat knitting machine, in the present utility model, it is preferred that the thicknesses of the main piece 10 and the auxiliary piece 20 are relatively thin, and the auxiliary piece 20 is attached to one side of the main piece 10. The space occupied after the main piece 10 and the auxiliary piece 20 are attached is close to the space occupied by the existing single sinker, so as to prevent affecting the operation of other components on the needle bed.

[0035] Among them, the corresponding sides of the main piece 10 and the auxiliary piece 20 are bent and extended, facilitating the sinker body 30 to surround and buckle from both sides of the coil 50, ensuring complete buckling of the coil 50 and preventing further movement of the coil 50. At the same time, the needle passing channel 42 formed between the main piece 10 and the auxiliary piece 20 also facilitates the protrusion and retraction of the knitting needle 41 and will not affect the normal operation of the knitting needle 41.

[0036] Such as Figure 5 and Figure 6As shown, preferably, the main piece 10 includes a first substrate 11, and a first pressing piece 12 extends outward from the first substrate 11. The auxiliary piece 20 includes a second substrate 21, and a second pressing piece 22 corresponding to the first pressing piece 12 is formed by extending outward from the second substrate 21. The two pressing pieces enclose the above-mentioned needle-passing channel 42, and the ends of the two pressing pieces are buckled on both sides of the coil 50.

[0037] In the present utility model, preferably, the main piece 10 is integrally formed by the first substrate 11 and the first pressing piece 12, and the auxiliary piece 20 is integrally formed by the second substrate 21 and the second pressing piece 22. Among them, the second substrate 21 is attached to the first substrate 11, and the second pressing piece 22 bends towards the first pressing piece 12 and encloses to form the above-mentioned needle-passing channel 42. During actual operation, the first pressing piece 12 and the second pressing piece 22 are buckled on the corresponding coil 50.

[0038] Furthermore, the first substrate 11 bends and transitions to the first pressing piece 12, and the second substrate 21 bends and transitions to the second pressing piece 22 after being bent twice continuously.

[0039] Preferably, the bending angle of the second pressing piece 22 is greater than that of the first pressing piece 12, and the ends of the two pressing pieces are partially crossed.

[0040] It is worth mentioning that the bending degrees of the first pressing piece 12 and the second pressing piece 22 are different here. In this embodiment, it is preferred that after the second pressing piece 22 is bent twice continuously relative to the second substrate 21 and is in a plane parallel to the second substrate 21, it bends towards the second pressing piece 22 again. At this time, the above-mentioned needle-passing channel 42 is formed between the first pressing piece 12 and the second pressing piece 22.

[0041] Preferably, the bending angle of the second pressing piece 22 is greater than that of the first pressing piece 12. After bending, the ends of the two pressing pieces are partially crossed. In view of the fact that the coil 50 is held when it moves to the position of the two pressing pieces, the structure in which the two pressing pieces are crossed here can further ensure the buckling effect of the two pressing pieces on the coil 50 and ensure that the coil 50 no longer moves.

[0042] Furthermore, a first notch 121 is formed at the bottom of the first pressing piece 12, and a second notch 221 is formed at the top of the second pressing piece 22. The first notch 121 is located above the second notch 221.

[0043] In this embodiment, it is preferred that after the two pressing pieces are bent, a part of the end of the second pressing piece 22 is located below the first pressing piece 12. The settings of the first notch 121 and the second notch 221 here facilitate the two pressing pieces not to interfere with each other when crossing.

[0044] Such as Figure 3 and Figure 4As shown, it is worth mentioning that after one loop formation is completed, the knitting needle 41 returns, and at this time, the cams drive each sinker body 30 (main piece 10, sub-piece 20) to rotate back and disengage from the coil 50. When the two pressing pieces on each sinker disengage from the coil 50, they will disengage from the knitting needle 41.

[0045] Preferably, the main piece 10 and the sub-piece 20 are made of elastic steel. The first pressing piece 12 and the second pressing piece 22 respectively disengage from the coil 50 against the knitting needle 41. Under the block of the knitting needle 41, the ends of the first pressing piece 12 and the second pressing piece 22 are separated from each other. After disengaging from the knitting needle 41, the ends of the first pressing piece 12 and the second pressing piece 22 are closed and crossed again under the elastic action. After the knitting needle 41 completely returns, the cams drive each sinker to rotate to the designated position again, waiting for the next buckling of the coil 50.

[0046] Preferably, reinforcing ribs 31 are respectively fixedly arranged on the opposite sides of the two pressing pieces, and the reinforcing ribs 31 extend along the corresponding pressing pieces in a curved manner. In view of the relatively thin thickness of the main piece 10 and the sub-piece 20, and the first pressing piece 12 and the second pressing piece 22 will frequently open and close, the setting of the reinforcing ribs 31 here can enhance the structural strength of the two pressing pieces, thereby increasing the overall service life of the sinker.

[0047] The length and width of the reinforcing ribs 31 can be set according to the actual size of the pressing pieces, and no limitation is made here.

[0048] Furthermore, two first positioning holes 111 are formed on the first base piece 11, two second positioning holes 211 corresponding to the two first positioning holes 111 are formed on the second base piece 21, and an installation hole 112 for the rotating shaft 43 to pass through is also formed at the bottom of the first base piece 11.

[0049] The setting of the first positioning holes 111 and the second positioning holes 211 here is convenient for the main piece 10 and the sub-piece 20 to be fitted and fixed on the one hand, and is also convenient for the sinker to be correctly installed at the corresponding position on the needle plate on the other hand. The setting of the installation hole 112 is convenient for the rotating shaft 43 to pass through, and can drive each sinker to rotate together during work, ensuring the smooth progress of the buckling work of the coil 50.

[0050] The structure of the combined flat knitting machine sinker is reasonably arranged. Through the combination of the main piece 10 and the sub-piece 20, the main piece 10 and the sub-piece 20 respectively buckle the two sides of the corresponding coil 50, enhancing the control degree of the coil 50, ensuring the overall buckling of the sinker to the coil 50, and avoiding the coil 50 moving along with the knitting needle 41 when the knitting needle 41 exits the needle and being unable to form a loop again. At the same time, a needle passing channel 42 is formed by enclosing between the main piece 10 and the sub-piece 20, providing space for the normal needle exit and return of the knitting needle 41, and avoiding the influence of the sinker structure on the needle plate structure of the flat knitting machine.

[0051] What is described in this text is only the preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Modifications, supplements or substitutions in a similar manner made by those skilled in the art to which the present utility model pertains to the specific embodiments described shall all be covered within the protection scope of the present utility model.
