Description

Technical Field

[0001] The utility model relates to the field of flat knitting machines, in particular to a sinker control mechanism for multiple systems. Background Art

[0002] Computerized flat knitting machine is a double needle plate latch needle weft knitting loom. Its triangle system is like a set of flat cams. The needle feet can enter the groove of the cam. The triangle system is moved to force the needle to make regular lifting and lowering movements in the needle groove. Through the action of the needle hook and the needle tongue, the yarn can be knitted into a knitted fabric. During the rising process of the knitting needle, the coil gradually withdraws from the needle hook, opens the needle tongue, and withdraws the needle tongue to hang on the needle bar; during the descent of the knitting needle, the needle hook hooks the newly placed yarn and pulls it to bend into a coil. At the same time, the original coil is removed from the needle hook, and the new coil passes through the old coil and is connected in series with the old coil. The coil strings formed by numerous knitting are connected to each other to form a knitted fabric.

[0003] The sinker is arranged next to each knitting needle. The sinker is set on the spacer and isolated from each other by the spacer. The sinker controls the old coil and new yarn on each knitting needle, assists the knitting needle to withdraw the coil, and can be rotated open relative to the needle bed mouth (weaving mouth) to make room for loop formation.

[0004] For example, in the prior patent CN116219619A (reference document 1), the needle push triangle system of the knitting machine, i.e., the sinker control device, is disclosed. Figure 6 As shown, it is arranged on a general weaving cam system, acts on the heel of the sinker, and pushes the sinker to swing.

[0005] However, the above-mentioned comparative document 1 uses multiple sets of push needles and connecting rods for a triangular weaving system, while the existing flat knitting machines more commonly use 2-4 sets of triangular systems. If the above-mentioned sinker control method is adopted, it will be too complicated and increase the burden on the machine head.

[0006] Therefore, the inventor conducted further research and developed a sinker control mechanism for multiple systems, which resulted in the present invention. Utility Model Content

[0007] The utility model aims to provide a sinker control mechanism for multiple systems, which has a simple structure and stable control and can improve weaving efficiency.

[0008] In order to achieve the above purpose, the technical solution of the utility model is as follows:

[0009] A sinker control mechanism for multiple systems includes a fixed bottom plate,

[0010] A guide groove acting on the heel of the sinker is provided on one side of the fixed bottom plate, and the guide groove crosses the fixed bottom plate and is symmetrically distributed on the left and right sides;

[0011] The guide groove includes an initial position, a needle starting position, an avoidance position, and an adjustment position from the side to the middle. The initial position and the avoidance position are of the same height, the needle starting position is located between the initial position and the avoidance position and is relatively high, the adjustment position is located in the middle, and the adjustment position is provided with an adjustment block that can move up and down.

[0012] When the sinker is in the initial position, the wire pressing part is lifted to the highest position. The initial position ensures that the sinker is in this position (left and right cycle) after each row of weaving is completed, so as to ensure that the shaking table can work normally when the circle is moved;

[0013] When the sinker is in the needle raising position, when starting to knit, the position of the thread pressing part (corresponding to the position of the needle raising triangle) slightly presses the coil to prevent the coil from rising with the knitting needle. It is also the starting position for the dynamic adjustment of loop or tuck knitting, and it is also the position that can ensure the normal operation of the shaking table.

[0014] When the sinker is in the avoidance position, the needle is hooking and bending the yarn, and the thread pressing part of the sinker is in the avoidance state to prevent the yarn from being pressed and wound on the pressing part surface, affecting the looping effect;

[0015] When the sinker is in the adjustment position, dynamic adjustment can be performed, and the thread pressing part can adjust the depth of the thread pressing through the adjustment block according to the size of the braided coil.

[0016] Furthermore, a connecting rod is provided on the other side of the fixed base plate, which can move relative to the fixed base plate, and a transverse driving groove is opened on the connecting rod, with an upward protrusion in the middle of the driving groove, and two rolling members are also provided in the driving groove, which are respectively linked to the two adjustment blocks. When the connecting rod moves, the rolling member can be lifted up by the protrusion, and the corresponding adjustment block moves upward in the guide groove.

[0017] By driving the connecting rod to move laterally, the rolling element can be moved to the raised portion, thereby selecting the position of the adjustment block in the guide groove, so that the heel position of the sinker can be selectively changed, thereby changing the pressing depth of the sinker.

[0018] Furthermore, the guide groove is from left to center or from right to center, with the groove tops of different heights of its sections as the standard: L1 section zero position, L2 section middle position, L3 section zero position, L4 section middle position, L5 section high position, L6 section middle position, and the sections of different heights are connected by continuous bevel edges.

[0019] L1 corresponds to the initial position, L2 corresponds to the needle starting position, L3 corresponds to the avoidance position, L5 corresponds to the adjustment position, L4 is the transition between the avoidance position and the adjustment position, and L6 is the transition between the two adjustment positions;

[0020] The zero position corresponds to the sinker not participating in the coil control; the middle position corresponds to the sinker participating in the control but not deeply pressing the coil (slightly pressing). At the zero position and the middle position, the front and rear needle beds can perform the coil transfer operation without worrying about the sinker colliding; the high position of the guide groove corresponds to the sinker deeply participating in the coil pressing to achieve the maximum bending depth (that is, the maximum swing amplitude).

[0021] Furthermore, the rolling element and the adjusting block are connected via respective mounting seats, and the mounting seats are arranged in a sliding groove that passes through the fixed bottom plate.

[0022] Furthermore, the slide groove is vertically or obliquely distributed relative to the guide groove.

[0023] Furthermore, a toothed edge is provided on the bottom edge of the connecting rod corresponding to the protruding portion, and the toothed edge is linked with the gear, and the gear is driven by the motor to move the connecting rod relative to the fixed bottom plate.

[0024] Since the guide grooves are symmetrically distributed and the protrusion is located in the middle of the driving groove, the gear of the driving connecting rod is set in the middle, which has the highest stability and is also convenient for debugging.

[0025] Furthermore, when one adjusting block rises in the adjusting position, the other adjusting block remains stationary.

[0026] After adopting the above scheme, the utility model has the following advantages compared with the prior art:

[0027] The pressing depth of the sinker during back and forth lateral movement can be controlled by a drive and a connecting rod, and the structure is simple and the operation is stable. At the same time, it can ensure that the sinkers will not collide with each other during the transfer of the circle. BRIEF DESCRIPTION OF THE DRAWINGS

[0040] The utility model is further described below in conjunction with the accompanying drawings and specific embodiments.

[0041] A sinker control mechanism for multiple systems includes a fixed base plate 1 (also called a mother plate in the prior art). The fixed base plate 1 mainly has a guide groove 2 on the front side for interacting with the sinker heel, and a movable groove on the back side for a connecting rod 3 to move horizontally to the left and right.

[0042] like Figure 1 As shown, refer to Figure 3 The guide groove 2 is a structure that penetrates the fixed bottom plate 1 and has different heights. The entrances at both ends are larger and then gradually shrink to facilitate the introduction of the sinker heel.

[0043] Based on the midline of the guide groove 2, it is symmetrically arranged on the left and right. Therefore, according to the height of each segment, it can be divided into L1 segment zero position, L2 segment mid position, L3 segment zero position, L4 segment mid position, L5 segment high position, L6 segment mid position (reference Figure 3 ), wherein, in the middle L5-L6 section (L6 mainly plays a transitional role), two adjustment blocks 21 are arranged, and the top of the adjustment block 21 is flush with the lower bottom edge of the L2, L4, and L6 sections; the above-mentioned zero position, middle position, and high position correspond to: the zero position corresponds to the sinker not participating in the coil control; the middle position corresponds to the sinker participating in the control but not performing deep pressing of the coil, at which time the front and rear needle beds can perform the coil transfer operation without worrying about the sinker causing collision; the high position of the guide groove 2 corresponds to the sinker deeply participating in the coil pressing, which can reach the maximum pressing depth.

[0044] like Figure 2As shown, a gear 31 is arranged in the middle of the bottom of the connecting rod 3, and the gear 31 is driven by a motor 32. A driving groove 4 is arranged on the connecting rod 3. The driving groove 4 is a structure with a middle protrusion and two sides arranged horizontally. It is also symmetrical with the middle of the protrusion as the reference line. Two rolling elements 41 are arranged in the driving groove 4, which correspond to the adjustment block 21 respectively; that is, in this embodiment, two oblique and through-type slide grooves are opened on the fixed bottom plate 1, and a mounting seat 5 is arranged in the slide groove. The mounting seat 5 is connected to the rolling element 41 and the adjustment block 21 respectively. When the connecting rod 3 is pushed to move horizontally in the moving groove, the relative height of the rolling element 41 changes due to the action of the driving groove 4, thereby pushing the height of the adjustment block 21 in the guide groove 2 to change. When one of the rolling elements 41 is pushed to the highest point of the protrusion, the corresponding adjustment block 21 will rise in the guide groove 2, so that the sinker becomes deep pressing when passing through the L5 section.

[0045] refer to Figure 4 The needle beds on both sides of the flat knitting machine are provided with sinkers 6 at the weaving opening, and the position corresponding to the heel of the sinker 6 is the guide groove 2 of the fixed bottom plate 1. Figure 4 The fixed bottom plate 1 in the figure is only a schematic diagram. In fact, the entire fixed bottom plate is arranged perpendicular to the picture. When the machine head moves back and forth, the heel of the sinker moves back and forth in the guide groove.

[0046] Figure 5 The state of the sinker in the guide groove 2 is the state of the initial position 22, that is, the zero position ( Figure 5-8 The fixed base plate shown in the figure is only a schematic diagram and does not constitute a relationship of size, relative position, etc.).

[0047] like Figure 6 As shown, the heel of the sinker in this state is in the middle position in the guide groove 2 (also corresponding to the needle starting position 23), that is, the sinker has participated in the work, but has not yet reached the maximum pressing depth. The needle beds on both sides can be shaken and transferred, and the sinkers will not interfere with each other.

[0048] like Figure 7 As shown, when the sinker is in the avoidance position 24, its state is the same as Figure 5 Similarly, the corresponding knitting needle is hooking the yarn and bending the yarn.

[0049] like Figure 8 As shown, the pressing portion 61 of the left sinker is in the maximum pressing depth state, that is, the state when the adjustment block rises in L5, and the right sinker is in a slight pressing state, that is, the state when it is in the middle position. By adjusting the up and down movement of the adjustment block in the adjustment position 25, the size of the required weaving coil is adjusted.

[0050] The above are only specific embodiments of the present utility model. At the same time, all words such as "upper, lower, left, right, middle" involved in the present utility model are for reference only and are not absolutely limiting. Any non-substantial changes made using the present utility model shall be deemed as an infringement of the protection scope of the present utility model.
