Description

Technical Field

[0001] The present application relates to the field of knitting technology, and in particular to a sendin device and a machine head having the sendin device. Background Art

[0002] The computerized flat knitting machine is a double-needle plate latch needle weft knitting loom, and the sinker device is an important component of the computerized flat knitting machine. The computerized flat knitting machine has a needle row plate, on which knitting needles are arranged, and the knitting needles perform knitting work. The needle row plate is generally also provided with a sinker, and the sinker has a pressing part and a lifting part. When weaving, the sinker device is used to lift the lifting part of the sinker to drive the sinker to rotate, so that the pressing part of the sinker presses the coil downward. The current sinker device has a large limitation on the adjustment range of the sinker. When pressing down on the weaving threads with different breaking strengths, its ability to adjust the pressing range is poor, which leads to poor weaving effect for the weaving threads with different breaking strengths.

[0003] With respect to the above-mentioned related technologies, the inventors believe that the current computerized flat knitting machine has a defect in that the sinker has a poor ability to adjust the downward pressure of wires with different breaking strengths. Summary of the invention

[0004] In order to improve the ability of the sinker to adjust the downward pressure of the yarns with different breaking strengths, the present application provides a sinker device and a machine head having the sinker device.

[0005] The present application provides a signal device and a head having the signal device, which adopts the following technical solutions:

[0006] A sinker device includes a mounting assembly and a sliding assembly, wherein the mounting assembly includes a mounting plate, and the sliding assembly includes a lifting block, wherein the lifting block is provided with a lifting groove, wherein the lifting groove is used to accommodate a lifting portion of a sinker plate, and wherein the mounting plate is provided with an adjusting groove, wherein the adjusting groove includes a first horizontal groove section and a first inclined groove section, wherein the first horizontal groove section and the first inclined groove section are alternately arranged, wherein the height position of the first horizontal groove section is successively reduced, and wherein at least three first horizontal groove sections are arranged, and wherein the lifting block is fixedly connected with an adjusting member, wherein the adjusting member has a circular adjusting portion, and wherein the adjusting portion is slidably matched with the adjusting groove; wherein the groove width of the first horizontal groove section is equal to the diameter of the adjusting portion, and the groove width of the first inclined groove section is also equal to the diameter of the adjusting portion.

[0007] By adopting the above technical solution, the adjusting member and the adjusting groove are slidably matched. For the weaving wire with lower breaking strength, the adjusting member is moved to the first horizontal groove section with lower position, so as to reduce the situation that the weaving wire is damaged and broken by excessive pressure of the sinker. For the weaving wire with higher breaking strength, the adjusting member is moved to the first horizontal groove section with higher position, so as to increase the downward pressure amplitude of the sinker on the weaving wire. Therefore, for the weaving wires with different breaking strengths, the adjusting member can be adjusted to different first horizontal groove sections according to their breaking strengths, so that the weaving wires are in a better weaving state.

[0008] In addition, when the position adjusting member switches to the first horizontal slot section with a large height difference, the multi-stage first inclined slot section can produce a better buffering effect, making the position adjusting member move more smoothly during height adjustment, thereby making the adjustment action of the sinker on the sinker more gentle, reducing the impulse of the downward pressure part of the sinker. Moreover, through the multi-stage adjustment method, the sinker can have a larger rotation range, and the downward pressure part of the sinker can press the coil lower, exerting a greater downward pressure on the fabric, thereby playing a better bottom auxiliary role. For some specific patterns, the downward pressure of the sinker on the fabric can replace the bottom lifting device.

[0009] Optionally, a first circular arc groove section is arranged between the adjacent first horizontal groove section and the first inclined groove section; the first circular arc groove section has a first inner arc wall and a first outer arc wall; the diameter of the first inner arc wall is smaller than the groove width of the first horizontal groove section, and the radius of the first outer arc wall is smaller than or equal to the groove width of the first horizontal groove section.

[0010] By adopting the above technical scheme, the adjusting part moves in the adjusting groove to adjust the position of the lifting block. During the movement of the adjusting part, the first circular arc groove section allows the adjusting part to receive a better transition effect when entering the first inclined groove section from the first horizontal groove section, or when entering the first inclined groove section from the first horizontal groove section, thereby making the movement of the adjusting part smoother and the position adjustment effect of the lifting block smoother and more stable; the radius of the first outer arc wall is less than or equal to the groove width of the first horizontal groove section, and the adjusting part is not easily obstructed when passing through the first circular arc groove section, thereby ensuring smooth movement of the adjusting part in the first circular arc groove section; the diameter of the first inner arc wall is less than the groove width of the first horizontal groove section, that is, the space occupied by the first circular arc groove section is controlled, so that the setting space of the first horizontal groove section and the first inclined groove section is stable.

[0011] Optionally, the diameter of the first inner arc wall is equal to 1 / 3 of the width of the first horizontal slot segment, and the diameter of the first outer arc wall is equal to the width of the first horizontal slot segment.

[0012] By adopting the above technical solution, the diameter of the first outer arc wall is equal to the slot width of the first horizontal slot segment, and the diameter of the first inner arc wall is equal to 1 / 3 of the slot width of the first horizontal slot segment. At this time, the movement of the adjustment part in the circular arc slot segment is smooth and stable.

[0013] Optionally, the lengths of the first inclined groove sections decrease gradually from low to high positions.

[0014] By adopting the above technical scheme, the lengths of the first inclined groove sections from low to high positions are gradually reduced, that is, the length of the first inclined groove section at the lower position is larger, which makes the height difference between the two first horizontal groove sections connected by the first inclined groove section at the lower position larger, and when the signal device starts to push the sinker, the adjustment part reaches a higher position faster, and the initial pushing effect of the signal device on the sinker is obvious; and the length of the first inclined groove section at the higher position is smaller, which makes the height difference between the two first horizontal groove sections locked and connected by the first inclined groove section at the higher position smaller, and when the signal device adjusts the pushing amplitude of the sinker, the adjustment effect is relatively smooth.

[0015] Optionally, the curvature of the first inner arc wall is equal to the curvature of the first outer arc wall, and the length of the first inclined groove segment at the highest position is 0.

[0016] By adopting the above technical solution, the length of the highest first inclined slot segment is 0. At this time, the two adjacent first horizontal slot segments are transitioned through two first circular arc slot segments, which minimizes the height difference between the highest first horizontal slot segment and the second highest first horizontal slot segment. When the adjustment part switches between the highest first horizontal slot segment and the second highest first horizontal slot segment, the signal device can adjust the downward pressure of the weaving thread most smoothly. The curvature of the first inner arc wall is equal to the curvature of the first outer arc wall, so that the two adjacent first circular arc slot segments can form central symmetry. At this time, the two adjacent first circular arc slot segments achieve a smoother transition effect.

[0017] Optionally, the adjustment groove further includes a second horizontal groove section and a second inclined groove section, the height positions of the second horizontal groove sections are successively increased, and the lowest first horizontal groove section is connected to the lowest second horizontal groove section.

[0018] By adopting the above technical scheme, the adjusting groove includes a second horizontal groove section, that is, the adjusting groove has more horizontal groove sections. On the one hand, the selectable moving directions of the adjusting member are increased, and on the other hand, the room for setting the height of the horizontal groove section is increased, thereby increasing the selectable position height of the adjusting member and improving the design flexibility and use flexibility of the signal device.

[0019] Optionally, the sliding assembly includes a horizontal slide, the mounting plate is provided with a horizontal slide, the horizontal slide is fixedly connected with a horizontal slide, and the horizontal slide is slidably matched with the horizontal slide; the horizontal slide is provided with a vertical slide, the number of the vertical slides is equal to the adjustment grooves and the positions correspond one to one, the lifting block is fixedly connected with a vertical slide, the vertical slide is slidably matched with the vertical slide, and the adjustment member is fixed to the vertical slide.

[0020] By adopting the above technical solution, the horizontal slide is fixed to the horizontal slide plate and slides with the horizontal slide groove, so that the horizontal slide plate is slidably connected to the mounting plate. The vertical slide is fixed to the lifting block and slides with the vertical slide groove, so that the lifting block and the horizontal slide plate slide vertically. When the horizontal slide plate slides in the horizontal direction, the adjustment part slides in the adjustment groove, and then the vertical slide plate slides in the vertical slide groove, that is, the lifting block slides vertically through the relative movement of the horizontal slide plate and the mounting plate, and the lifting control effect of multiple lifting blocks can be achieved simultaneously.

[0021] Optionally, the horizontal slide includes a spacer portion, a horizontal sliding portion and a smooth limiting portion connected in sequence, the horizontal sliding portion slidingly cooperates with the horizontal slide groove, the spacer portion is attached to the side of the mounting plate facing the horizontal slide, and the smooth limiting portion is attached to the side of the mounting plate facing away from the horizontal slide; the vertical slide includes a vertical sliding portion and a vertical sliding limiting portion, the vertical sliding portion is fixed to the lifting block, the vertical sliding portion slidingly cooperates with the vertical slide groove, and the vertical sliding limiting portion is attached to the horizontal slide.

[0022] By adopting the above technical solution, the spacer part and the smooth limit part clamp the mounting plate, so that the sliding cooperation effect between the horizontal slide and the horizontal slide groove is stable. At the same time, the vertical slide limit part and the lifting block clamp the horizontal slide, so that the sliding cooperation effect between the vertical slide and the vertical slide groove is stable.

[0023] Optionally, the horizontal slide is fixedly provided with a guide assembly, the number of the guide assemblies is equal to the number of the lifting blocks and the positions correspond one to one, the guide assembly includes two guide blocks, the lifting block is located between the two guide blocks at corresponding positions, and the spacing between the two guide blocks is equal to the length of the lifting block; the guide block is also connected to a guide plate, and the lifting block is provided with a guide groove for slidingly cooperating with the guide plate.

[0026] By adopting the above technical solution, the driving motor drives the gear to rotate, and the meshing of the gear and the rack causes the rack to move, thereby driving the horizontal slide to slide, thereby achieving a better movement control effect.

[0027] In summary, the signaling device of the present application includes at least one of the following beneficial technical effects:

In particular, when the height difference between the two adjacent first horizontal slot sections 121 is the smallest, the length of the first inclined slot section 122 is 0, and at this time, the two adjacent first horizontal slot sections 121 transition through the two first arc slot sections 123. In this embodiment, the length of the first inclined slot section 122 located at the top is preferably 0, so that the height difference between the highest first horizontal slot section 121 and the second highest first horizontal slot section 121 is the smallest, and at this time, the pressure adjustment of the weaving thread by the signal device is the smallest, that is, the downward pressure adjustment of the weaving thread is the most gentle.

[0046] In other embodiments, the number of the first horizontal slot sections 121 can be set according to the specific system settings on the machine head, and the diameter of the adjustment portion 61 and the slot width of the first horizontal slot sections 121 can be reasonably set according to the size of the mounting plate 1.

[0047] Reference Figure 5, the lifting block 5 is provided with a lifting groove 51, and the lifting groove 51 is used to accommodate the lifting part of the sinker. The lifting groove 51 includes two upper lifting groove sections 511 and a flat lifting groove section 512, and the two upper lifting groove sections 511 are located on both sides of the flat lifting groove section 512, and the bottom wall of the upper lifting groove section 511 gradually decreases from the side close to the flat lifting groove section 512 to the side away from the flat lifting groove section 512. A guide assembly 8 is also fixedly provided on the horizontal slide 2, and the number of guide assemblies 8 is equal to that of the lifting block 5 and the positions correspond one to one. The guide assembly 8 includes two guide blocks 81, and the two guide blocks 81 are respectively located on both sides of the lifting block 5 at the corresponding position, and the spacing between the two guide blocks 81 is equal to the length of the lifting block 5 to horizontally limit the lifting block 5. There is also a guide piece 811 on the side where the two guide blocks 81 of the same guide assembly 8 are close to each other, and the position of the lifting block 5 corresponding to the guide piece 811 is provided with a guide groove 52, and the guide piece 811 is slidably matched with the guide groove 52 at the corresponding position. The guide groove 52 is connected to the upper lifting groove section 511, and the angle between the bottom edge of the guide piece 811 and the bottom wall of the horizontal lifting groove section 512 is less than 10 degrees, which can be 5 degrees or 0 degrees. When the positioning member 6 is located in the highest horizontal groove section, the minimum distance between the bottom edge of the guide piece 811 and the bottom wall of the horizontal lifting groove section 512 is equal to or greater than the width of the horizontal lifting groove section 512.

[0048] On the other hand, this embodiment discloses a head, referring to Figure 3 and Figure 7 , including a machine head body and the above-mentioned signal device, a mounting angle plate 9 is provided on the side of the mounting plate 1 facing away from the horizontal slide 2, the mounting angle plate 9 includes a first connecting portion 91 and a second connecting portion 92, the first connecting portion 91 is fixed to the mounting plate 1 by screws, a pad is preferably provided between the first connecting portion 91 and the mounting plate 1, the pad and the first connecting portion 91 are simultaneously fixed to the mounting plate 1 by screws.

[0049] The equal dimensions mentioned in this embodiment are basic equal dimensions in mechanical design, and dimensional tolerances can be set on this basis. For example, the slot width of the first horizontal slot segment 121 is equal to the diameter of the adjustment portion 61, which means that the basic dimension of the slot width of the first horizontal slot segment 121 is equal to the basic dimension of the diameter of the adjustment portion 61. The slot width of the first horizontal slot segment 121 can be set with an upper deviation on the basis of the basic dimension, and the diameter of the adjustment portion 61 can be set with a lower deviation on the basis of the basic dimension, so that the sliding fit between the adjustment portion 61 and the first horizontal slot segment 121 is stable.

[0050] Example 2

[0051] The difference between Example 2 and Example 1 is that: Figure 6 , there is a height difference between any second horizontal slot section 124 and any first horizontal slot section 121. Compared with embodiment 1, in this embodiment, the position adjustment of the lifting block 5 by the adjustment part 61 in the second horizontal slot section 124 is different from that by the adjustment part 61 in the first horizontal slot section 121, so that the sinker device has more adjustment range options.

[0052] The implementation principle of a sender device and a machine head with the sender device in an embodiment of the present application is as follows: the adjusting member 6 cooperates with the adjusting slot 12 to move the lifting block 5. For the weaving wire with lower breaking strength, the adjusting member 6 is moved to a lower horizontal slot section to reduce the situation where the weaving wire is damaged and broken due to excessive pressure from the sinker. For the weaving wire with higher breaking strength, the adjusting member 6 is moved to a higher horizontal slot section to increase the downward pressure of the sinker on the weaving wire. Therefore, for the weaving wires with different breaking strengths, the adjusting member 6 can be respectively located in different horizontal slot sections to make the weaving wire in a better weaving state. In addition, when the adjusting member 6 switches the horizontal slot section with a larger height difference, the multi-section inclined slot section can produce a better buffering effect, so that the action of the adjusting member 6 during height adjustment is smoother, thereby making the adjustment action of the sinker block on the sinker smoother, reducing the impulse of the downward pressure part of the sinker. Moreover, through multi-stage adjustment, the sinker can be set to rotate in a larger range, and the downward pressure part of the sinker can press the coil lower, exerting a greater downward pressure on the fabric, thereby playing a better auxiliary role in bottoming. For some specific patterns, the downward pressure of the sinker on the fabric can replace the bottoming device.

[0053] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
