Description

TECHNICAL FIELD

[0001] The present application belongs to the mechanical technical field, and relates to a combined computerized flat knitting machine sinker, in particular to a normally closed computerized flat knitting machine sinker. BACKGROUND

[0002] The sinker is a kind of accessory for textile machinery, and plays a role of pulling loops on the computerized flat knitting machine. The sinker is arranged beside each needle, and can well control the old loops and new yarn on each needle, which is beneficial to weaving three-dimensional fabrics with three-dimensional effect, and facilitates full-form weaving such as bag opening and door access.

[0003] The sinker is installed on the needle plate with the needle, and is controlled by the cam rail on the machine head. The cam makes the sinker move forward, presses the fabric when the needle rises, and assists in loop withdrawal; or retreats when the needle descends, and prepares for loop withdrawal. The setting of the sinker is generally divided into normally open or normally closed. The normally open sinker presses the loop when the machine head weaves, and is in a disengaged state at other times, and is generally used in computerized flat knitting machines with a rise plate, which can provide sufficient clearance in cooperation with the rise plate. The normally closed sinker is disengaged when the machine head weaves, and presses the loop after weaving is completed, and is in a pressed state at other times, and continuously applies pressure to the woven piece. It is generally applicable to devices without tension rise.

[0004] Most of the existing sinkers adopt a normally open structure, and are mostly provided in a one-piece manner. When in use, the position of the sinker after being pressed down is usually at the connection between two loops, at which time the force applied to the loop is relatively small. When the needle is brought out to weave by the cam, the old loop is easily carried by the needle, which is not conducive to the needle picking up the new yarn to form a loop. If the force applied to the loop by the sinker is increased, the loop is easily broken, and the use effect is not ideal.

[0005] In view of the above, in order to solve the problems of the existing computerized flat knitting machine sinker structure, the present application designs a combined computerized flat knitting machine sinker with reasonable structure and good use effect. SUMMARY

[0006] The present application provides a combined computerized flat knitting machine sinker with reasonable structure and good use effect to solve the problems in the prior art.

[0007] The purpose of the present application can be achieved by the following technical scheme: a combined computerized flat knitting machine sinker, comprising:

[0008] A body is installed at the front end of the needle plate of the computerized flat knitting machine, and is composed of a main piece and a sub-piece arranged in close contact. The main piece and the sub-piece are respectively curved and extended on the corresponding side, and form a needle passing channel.

[0009] The knitting needle is arranged on the needle plate, the body is arranged between two adjacent knitting needles, and each knitting needle can pass through the needle passing channel on the corresponding body during knitting.

[0010] The rotating shaft is arranged at the bottom of the main sheet, the main sheet drives the auxiliary sheet to rotate around the rotating shaft to a specified position, and the loop on the fabric moves to the specified position with the knitting needle, and the main sheet and the auxiliary sheet are buckled on both sides of the corresponding loop.

[0011] As a further improvement of the present application, the main sheet comprises a first base sheet, the first base sheet extends outwardly to form a first pressing sheet, the auxiliary sheet comprises a second base sheet, the second base sheet extends outwardly to form a second pressing sheet corresponding to the first pressing sheet, and the two pressing sheets form the needle passing channel and the end portions of the two pressing sheets are buckled on both sides of the loop.

[0012] As a further improvement of the present application, the first base sheet is bent to the first pressing sheet, and the second base sheet is bent to the second pressing sheet after being bent twice.

[0013] As a further improvement of the present application, the angle of the second pressing sheet is greater than the angle of the first pressing sheet, and the end portions of the two pressing sheets are partially crossed.

[0014] As a further improvement of the present application, the first pressing sheet is provided with a first gap at the bottom, the second pressing sheet is provided with a second gap at the top, and the first gap is located above the second gap.

[0015] As a further improvement of the present application, the two pressing sheets are respectively provided with a reinforcing rib at the opposite side, and the reinforcing rib extends along the corresponding pressing sheet.

[0016] As a further improvement of the present application, the first base sheet is provided with two first positioning holes, the second base sheet is provided with two second positioning holes corresponding to the two first positioning holes, and the first base sheet is further provided with a mounting hole for the rotating shaft.

DETAILED DESCRIPTION

[0025] The technical solutions of the present application are further described below in combination with embodiments and the accompanying drawings.

[0026] As Figure 1 and Figure 2 shown, the combined computerized flat knitting machine sinker comprises:

[0027] The body 30 is installed at the front end of the needle plate of the computerized flat knitting machine, and the body 30 is composed of the main piece 10 and the auxiliary piece 20 arranged in close contact with each other, and the main piece 10 and the auxiliary piece 20 are respectively curved and extended on the corresponding side and are combined to form the needle passing channel 42;

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

[0029] The rotating shaft 43 is arranged at the bottom of the main piece 10, and the main piece 10 drives the auxiliary piece 20 to rotate around the rotating shaft 43 to a specified position, and when the loop 50 on the fabric moves to the specified position with the needle 41, the main piece 10 and the auxiliary piece 20 are buckled on the two sides of the corresponding loop 50.

[0030] Most of the existing sinkers adopt the normally open structure, and are mostly arranged in one piece. When in use, the position of the sinker after being pressed down is usually at the connection between two loops, at which time the force applied to the loop is relatively small. When the cam drives the needle to knit, the old loop is easily driven by the needle, which is not conducive to the needle to pick up the new yarn for loop knitting. If the force applied to the loop by the sinker is increased, the loop is easily broken, and therefore, the existing sinker structure is not ideal in use.

[0031] To this end, the application provides a combined sinker of a computerized flat knitting machine, in particular a normally closed sinker, which is combined by a main piece 10 and a secondary piece 20, so that the main piece 10 and the secondary piece 20 respectively hold two sides of a corresponding loop 50, thereby enhancing the control degree of the loop 50 and ensuring that the sinker as a whole holds down the loop 50, so as to avoid the loop 50 from moving with the needle 41 when the needle 41 is withdrawn, and thus failing to form a loop again; meanwhile, a needle passage 42 is formed between the main piece 10 and the secondary piece 20, thereby providing space for the needle 41 to normally withdraw and return, and avoiding the sinker structure from affecting the needle plate structure of the computerized flat knitting machine.

[0032] The sinker is actually arranged on the needle plate together with the needle 41, and each needle 41 is equipped with a sinker, which is arranged in a spaced manner with the needle 41 and coaxially arranged and connected through a rotating shaft 43.

[0033] In operation, each sinker is driven by a cam of the computerized flat knitting machine to rotate around the rotating shaft 43 by a certain angle, and the sinker reaches a designated position; when the needle 41 is withdrawn, the loop 50 on the needle 41 will move a small distance, and when the loop 50 reaches the position of the sinker, it will be held by the main piece 10 and the secondary piece 20 and will not move upward with the needle 41, so as to realize the holding down of the loop 50 by the sinker body 30 (the main piece 10 and the secondary piece 20), and ensure that the loop 50 is completely held down.

[0034] Specifically, in view of the compact structure of the needle plate of the computerized flat knitting machine, the thickness of the main piece 10 and the secondary piece 20 is relatively thin in the application, and the secondary piece 20 is attached to one side of the main piece 10, so that the space occupied by the main piece 10 and the secondary piece 20 after being attached is close to the space occupied by the existing single sinker, thereby avoiding affecting the work of other parts on the needle plate.

[0035] Specifically, in view of the compact structure of the needle plate of the computerized flat knitting machine, the thickness of the main piece 10 and the secondary piece 20 is relatively thin in the application, and the secondary piece 20 is attached to one side of the main piece 10, so that the space occupied by the main piece 10 and the secondary piece 20 after being attached is close to the space occupied by the existing single sinker, thereby avoiding affecting the work of other parts on the needle plate.

[0036] As shown in FIGS. 1 to 4, preferably, the main piece 10 comprises a first base piece 11, the first base piece 11 extends outward to form a first pressing piece 12, the secondary piece 20 comprises a second base piece 21, the second base piece 21 extends outward to form a second pressing piece 22 arranged correspondingly to the first pressing piece 12, the two pressing pieces form the needle passage 42 and the end portions of the two pressing pieces are held down on both sides of the loop 50. Figure 5 Figure 6

[0037] ​​The main piece 10 is preferably integrally formed by the first base piece 11 and the first pressing piece 12, and the auxiliary piece 20 is integrally formed by the second base piece 21 and the second pressing piece 22, wherein the second base piece 21 is attached to the first base piece 11, and the second pressing piece 22 is bent towards the first pressing piece 12 to form the needle passing channel 42, and in actual work, the first pressing piece 12 and the second pressing piece 22 are buckled on the corresponding coil 50.

[0038] Further, the first base piece 11 is bent to the first pressing piece 12, and the second base piece 21 is bent twice to the second pressing piece 22.

[0039] Preferably, the second pressing piece 22 is bent at an angle greater than the first pressing piece 12, and the two pressing piece end portions are partially crossed.

[0040] It is worth mentioning that the first pressing piece 12 and the second pressing piece 22 are not bent to the same extent, and in the embodiment, the second pressing piece 22 is bent again after being bent twice relative to the second base piece 21 and being in the parallel plane of the second base piece 21, and the first pressing piece 12 and the second pressing piece 22 form the needle passing channel 42.

[0041] Preferably, the second pressing piece 22 is bent at an angle greater than the first pressing piece 12, and the two pressing piece end portions are partially crossed.

[0042] Further, the first pressing piece 12 is provided with a first gap 121 at the bottom, and the second pressing piece 22 is provided with a second gap 221 at the top, and the first gap 121 is located above the second gap 221.

[0043] In the embodiment, the two pressing pieces are bent, and the end portion of the second pressing piece 22 is located below the first pressing piece 12, and the first gap 121 and the second gap 221 are provided to prevent interference when the two pressing pieces are crossed.

[0044] As shown in Figure 3 and Figure 4 It is worth mentioning that when the first loop is completed, the needle 41 is returned, and at this time, the cam drives each sinker body 30 (the main piece 10 and the auxiliary piece 20) to rotate back to separate from the coil 50, and the two pressing pieces on each sinker are separated from the needle 41 when separating from the coil 50.

[0045] Preferably, the main sheet 10 and the auxiliary sheet 20 are made of elastic steel material, the first pressing sheet 12 and the second pressing sheet 22 are respectively separated from the loop 50 by the knitting needle 41, and the first pressing sheet 12 and the second pressing sheet 22 are separated from each other at the end under the block of the knitting needle 41, and the end of the first pressing sheet 12 and the end of the second pressing sheet 22 are folded again under the elastic effect after being separated from the knitting needle 41; after the knitting needle 41 is completely returned, the cam again drives each sinker to rotate to the designated position, and waits for the next pressing of the loop 50.

[0046] Preferably, the two pressing sheets are respectively fixed with the reinforcing ribs 31 at the opposite sides, and the reinforcing ribs 31 extend along the corresponding pressing sheets. Since the thickness of the main sheet 10 and the auxiliary sheet 20 is relatively thin, and the first pressing sheet 12 and the second pressing sheet 22 frequently open and close, the reinforcing ribs 31 arranged here can enhance the structural strength of the two pressing sheets, thereby increasing the overall service life of the sinker.

[0047] The length and width of the reinforcing rib 31 can be set according to the actual size of the pressing sheet, which is not limited here.

[0048] Further, the first base sheet 11 is provided with two first positioning holes 111, the second base sheet 21 is provided with two second positioning holes 211 corresponding to the two first positioning holes 111, and the first base sheet 11 is further provided with a mounting hole 112 for the rotating shaft 43 to pass through.

[0049] The arrangement of the first positioning hole 111 and the second positioning hole 211 on the one hand facilitates the fixation of the main sheet 10 and the auxiliary sheet 20, and on the other hand facilitates the correct installation of the sinker at the corresponding position of the needle plate, and the arrangement of the mounting hole 112 facilitates the penetration of the rotating shaft 43, which can drive each sinker to rotate together during work, ensuring the smooth pressing of the loop 50.

[0050] The combined computerized flat knitting machine sinker structure is reasonably arranged, the main sheet 10 and the auxiliary sheet 20 are combined to hold the two sides of the corresponding loop 50, thereby enhancing the control of the loop 50 and ensuring the overall pressing of the sinker on the loop 50, avoiding the movement of the loop 50 when the knitting needle 41 is withdrawn, and the loop 50 cannot form a loop again; at the same time, the main sheet 10 and the auxiliary sheet 20 form a needle penetration channel 42, providing space for the normal withdrawal and return of the knitting needle 41, and avoiding the influence of the sinker structure on the needle plate structure of the computerized flat knitting machine.
