AI Technical Summary
Existing settling plate control methods have failed to effectively solve the problems of yarn breakage or old loops not being pressed, resulting in difficulties in the weaving process.
By setting multiple movable triangles on the settling plate control base plate, the pressing degree of the settling plate can be flexibly adjusted. The pressing state of the settling plate can be adjusted in real time according to the needs of the weaving stage, ensuring that the new coil is not affected by the old coil and the old coil is not over-pressed.
This ensures that new coils are not affected by old coils during the weaving process, and that old coils are less likely to break, allowing the weaving to proceed smoothly and improving the weaving quality.

Technical Field
[0001] This utility model relates to the field of flat knitting machines, and specifically refers to a settling sheet control structure. Background Technology
[0002] A computerized flat knitting machine is a double-needle plate-latch weft knitting machine. Its cam system is like a set of planar cams. The needle feet can enter the grooves of the cams. Moving the cam system forces the needles to make regular up-and-down movements within the needle grooves. Through the actions of the needle hook and the needle latch, the yarn can be knitted into fabric. During the upward movement of the needle, the loops gradually exit the needle hook, the needle latch opens, and the needle latch exits and hangs on the needle bar. During the downward movement of the needle, the needle hook catches the newly placed yarn and pulls it to bend into a loop. At the same time, the existing loops exit the needle hook, and the new loops pass through the old loops and are connected in series. Numerous loops knitted together form the knitted fabric.
[0003] The sinker, positioned next to each needle, controls the old loops and new yarns on each needle, assisting the needle in unwinding. It can rotate and open relative to the needle bed (knitting edge) to make room for loop formation.
[0004] The existing sinker control method is relatively simple. Generally, the sinker is controlled by raising and lowering the triangle on the base plate to push the sinker heel, thereby adjusting the sinker. However, it does not strictly consider the problems that may occur in each weaving step, such as yarn breakage or old loops not being pressed down by the sinker and passing through the new loop.
[0005] Therefore, the inventors conducted further research and developed a settling plate control structure, which led to this invention. Utility Model Content
[0006] The purpose of this invention is to provide a settling plate control structure that controls the tightness of the coil through real-time adjustment of the settling plate.
[0007] To achieve the above objectives, the technical solution of this utility model is as follows:
[0008] A settling plate control structure, including
[0009] The control base plate is provided with a first area, a second area and a third area. The second area is located in the middle of the settlement plate control base plate and includes a left anti-lifting eye line area and a right anti-lifting eye line area. The first area and the third area are located on both sides of the second area.
[0010] Among them, the left and right anti-hanging eye line areas are each equipped with a movable triangle that can move up and down, and the first or third area is equipped with 1-2 movable triangles that can move up and down;
[0011] When the triangle in the first area on the left rises, the first area is the starting stitch area. The triangle in the left anti-hanging stitch area does not rise, while the triangle in the right anti-hanging stitch area rises.
[0012] When the triangle in the third area on the right rises, the third area is the starting stitch area. The triangle in the right anti-dangling stitch area does not rise, while the triangle in the left anti-dangling stitch area rises.
[0013] The knitting head moves back and forth relative to the fixed needle bed, meaning the knitting needles on the needle bed move back and forth relative to the triangular base plate on the knitting head. The left and right starting points are both referenced to the triangular base plate. Since the sinker plates work in coordination with their respective knitting needles, and the sinker plate control base plate is located above the triangular base plate, the knitting needles move from left to right, meaning the needle heel of the sinker plate moves from left to right on the sinker plate control base plate. Generally speaking, when the triangle on the sinker plate control base plate rises, it is equivalent to raising the heel of the sinker plate, causing the yarn pressing part (nozzle) of the sinker plate to press down on the loop. The above technical solution, by controlling the continuous swing of the sinker plates, flexibly adapts to the state of the yarn and knitting needles at each stage of knitting, thereby ensuring the smooth progress of knitting.
[0014] Furthermore, each of the first and third regions is provided with two movable triangles. When the first or third region is used as the starting point for pressing the line, one of the movable triangles applies medium pressing to the settling sheet when it rises, while the other movable triangle applies deep pressing to the settling sheet when it rises.
[0015] The degree to which the movable cam presses the sinker against the thread depends on the distance the knitting needle extends beyond the needle bed during the starting stitch.
[0016] Furthermore, the first / third area corresponds to the area where the starting triangle of the triangle base plate is located, and the second area corresponds to the area where the Zhongshan triangle of the triangle base plate is located.
[0017] Furthermore, on the outer side of the first or third region, there is also a pressure float triangle. When the needle is started on the left, the pressure float triangle on the right rises to press down the settling plate. When the needle is started on the right, the pressure float triangle on the left rises to press down the settling plate.
[0018] Before starting a new stitch after removing the old coil, press down on the old coil to prevent it from floating up.
[0019] Furthermore, when a pressure float triangle is provided, four movable triangles are also provided between the two pressure float triangles.
[0020] Furthermore, during the knitting process, the movable triangle in the second area controls the sinkers on both sides of the needle bed to be in a state of non-overlapping at the needle bed opening.
[0021] When turning the needle and moving the needle, the needle bed needs to be automatically adjusted by shaking the needle bed. Therefore, the sinkers on both sides cannot overlap at the needle bed opening, otherwise a collision will occur.
[0022] By adopting the above solution, this utility model has the following advantages compared with the prior art:
[0023] By adjusting the settling plate in real time, it can be ensured that the new coil is not affected by the old coil, and the old coil will not break due to being constantly pressed by the settling plate. Attached Figure Description

[0036] Fourth triangle 14, Fifth triangle 15, Sixth triangle 16, Fixed triangle 17;

[0039] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.
[0040] Since the knitting machine head moves back and forth, the functional triangles on the triangular base plate and the sinker control base plate are symmetrical. In this embodiment, with reference to the angle of the attached drawing, the knitting needle moves from right to left relative to the triangular base plate (in essence, the knitting head drives the triangular base plate to move, pushing the knitting needle to move on the needle bed). Correspondingly, in the sinker control base plate above the triangular base plate 2, the sinker heel also moves from right to left.
[0041] Meanwhile, in the actual flat knitting machine, the needle beds on both sides are set at a relative angle. The needle hooks are fed by the yarn feeder at the needle bed opening. The diagram in the instruction manual is only a schematic diagram for ease of explanation and does not represent the actual structural distribution. The triangular base plate 2 of the flat knitting machine commonly uses three sets of knitting triangle systems shared by all three (see attached diagram). Figure 8 ), in the appendix Figure 1-7 The image only shows one triangular system, in which... Figure 1 The diagram shows the division of the areas of the settlement control base plate 1 (the area division is only a rough reference and the dotted lines are not absolute). In the middle of the settlement control base plate 1 are two adjacent anti-lifting eyelet pressing areas, while the two sides of the settlement control base plate 1 are the starting pressing area / circular unwinding area. The latter two areas can be switched back and forth according to the different starting directions of the needle.
[0042] The following Example 1 illustrates the process by starting the needle on the right side and exiting it on the left side:
[0043] like Figure 2 As shown, under normal knitting conditions, when a new row of loops is started, the knitting needle 4 starts from the starting triangle 21 and rises (actually, the long needle heel below the knitting needle acts on the base plate 2 of the triangle and interacts with the starting triangle 21). At this time, the heel 31 of the sinker corresponding to the knitting needle begins to enter the track of the first triangle 11 on the sinker control base plate 1, driving the first triangle 11 to rise. Then, the heel 31 of the sinker is in a deep pressing state at the needle bed opening. The pressing parts of the sinkers 3 on both sides of the needle bed are in a staggered state in space. The old loops that have been knitted at the needle bed opening are pressed by the sinker 3, thereby ensuring that the knitting needle hook will not penetrate into the old loops in the deep pressing state when it extends.
[0044] like Figure 3As shown, the knitting needle continues to move upward along the starting triangle 21, and the needle hook begins to emerge from the needle bed opening. Correspondingly, the heel 31 of the corresponding sinker plate begins to move from the track of the first triangle 11 to the track of the second triangle 12. At this time, the second triangle 12 is also in an upward state, but its track position is lower than that of the first triangle 11. This is reflected in the sinker plate 3's pressing part being in a medium pressing state at the needle bed opening, which is equivalent to the sinker plate 3 loosening the pressing of the old loops somewhat (at this time, the existing yarn in the needle hook has not unhooked to form a loop, but can also be regarded as the newest "old loop"). This can prevent the old loops from breaking due to excessive pressing when the knitting needle continues to rise. Since the needle hook has now passed through to the needle bed opening, it will not pass through the old loops at the edge of the needle bed opening. Therefore, the heel 31 of the sinker plate can switch from a deep pressing state to a medium pressing state.
[0045] like Figure 4 As shown, at this time, the knitting needle has reached the top of the starting triangle 21 and is at the bottom of the middle triangle 22. At this time, the heel 31 of the sinker has entered the track of the second triangle 12, that is, the sinker 3 is in a medium pressure state. At this position, the sinker 3 can just seal the needle bed opening, preventing the old loop from following, but it will not put too much pressure on the loop to break the yarn, and it will not affect the subsequent yarn loop formation.
[0046] like Figure 5 As shown, after the knitting needle rises and falls through the cam 22 to prepare for hooking new yarn, the old loop begins to slide down from the needle tongue. If the loop cannot adhere to the needle bar at this point, the open needle tongue 41 may re-enter the old loop as the knitting needle 4 descends, failing to complete the unwinding of the old loop. Therefore, the fourth cam 14 needs to be raised here to bring the sinker 3 back into a deep pressing state, tightening the loop and preventing the needle tongue from inserting into the old loop. The third cam 13, between the second cam 12 and the fourth cam 14, is in a descending state during the aforementioned process, and will rise when the knitting head moves in the opposite direction. Therefore, the third cam 13 and the fourth cam 14 can be made into a split structure, that is, the upper half of the track they form can be made into a fixed cam 17, and the lower half is a movable cam, with the lower half considered as the main body of the third cam 13 and the fourth cam 14.
[0047] like Figure 6 As shown, the knitting needle continues to descend and hook the new yarn. Since the old loop is already below the needle tongue, the old loop begins to push the needle tongue to close as the knitting needle descends. The needle tongue can no longer insert the old loop. At this time, the heel 31 of the sinker begins to move from the track at the fourth triangle 14 to the track at the fifth triangle 15, which is in a descending state. At the needle bed opening, the sinker 3 begins to retreat to prevent the loop from breaking when the loop is unhooked later and to prevent it from affecting the formation of the new loop later.
[0048] like Figure 7As shown, since the subsequent knitting needles continue to descend after hooking the yarn to prepare to form a new loop, the old loop rises and begins to unravel. At this time, the sinker 3 does not need to perform the yarn pressing action. Therefore, the fifth triangle 15 and the sixth triangle 16 are in the descending state. When the heel 31 of the sinker passes, the sinker 3 retracts and is in the non-pressing state.
[0049] When the knitting needle moves from left to right relative to the triangular base plate 2, the triangle on the left side of the sinker control base plate 1 can be regarded as the first triangle 11, and the triangle on the right side can be regarded as the sixth triangle 16.
[0050] If the flat knitting machine is performing drop stitch knitting, the heel of the long needle will not pass through the Zhongshan triangle 22, and the knitting needle will not rise to the highest point of the needle bed. Therefore, at this time, the third triangle 13 and the fourth triangle 14 are both in a descending state during the drop stitch knitting process.
[0051] If you want to ensure that the old loops don't float up after the loops have unraveled and before the new loops are woven, you can add a pressing motion after that area, such as... Figure 9 In the second embodiment shown, the third triangle 13 and the fourth triangle 14 in the middle are still the anti-hanging stitch pressing area. The two sides of the anti-hanging stitch pressing area are the starting stitch pressing area / loop unwinding area. However, in the area of the second embodiment, only the second triangle 12 and the fifth triangle 15 are set in the starting stitch pressing area / loop unwinding area. The first triangle 11 and the sixth triangle 16 on the outermost side of the sinker control base plate 1 are used as sinker triangles to press the float. That is, after a loop is woven, the sinker 3 presses down once and then lifts up. The lifting action here is achieved by the fixed triangle 17.
[0052] Due to the limitation of the width of the triangular base plate 2, the solution in Embodiment 2 cannot be used in a single braiding system. Therefore, it is applied to a three-system. By setting one set on each side of the three-system, the old coil can be pressed into a floating wire before the machine head changes direction.
[0053] The above are merely specific embodiments of this utility model. Furthermore, terms such as "upper," "lower," "left," "right," and "middle" used in this utility model are for reference only and are not absolute limitations. Any non-substantial modifications made to this utility model shall be considered as infringing upon the protection scope of this utility model.
