Description
Technical Field
[0001] The utility model relates to the technical field of flat knitting machines, in particular to a sinker cam for flat knitting machines. Background Art
[0002] The glove machine mainly realizes knitting through the head triangle knitting system and the sinker triangle to drive the knitting needles and sinker pieces to move respectively. The sinker piece is also called the sinker piece. In the knitting process, looping is an indispensable knitting requirement. The sinker piece and the sinker triangle form a knitting wire pressing mechanism to press the coil and help looping. Through the sinker triangle, the sinker piece is pushed to the specified position, so that the sinker piece can press the sinker arc between the two knitting needles, and prevent the sinker arc from rising with the needle, so as to complete the knitting action.
[0003] The sinker triangle usually controls the up and down movement of the sinker piece by controlling different positions on the sinker piece, wherein the sinker triangle has parallel upper and lower track curves, and utilizes multiple braided line segments on the upper and lower track curves to respectively control the upper and lower action surfaces of the sinker piece to achieve the purpose of assisting loop formation.
[0004] The upper track curve and the lower track curve of the existing sinker triangle used for double-sided weaving form a left weaving line segment and a right weaving line segment, and the main yarn and the elastic thread are woven together with the sinker piece. When weaving the elastic thread, the sinker piece needs to be used to insert the elastic thread and press the elastic thread down to the coil position and insert the elastic thread into the coil, so as to weave the elastic thread into the main yarn. However, each sinker piece needs to move along a predetermined track and insert the elastic thread. Moreover, there are too many sinkers involved in weaving, but too many insertion points of the elastic thread. In the process of pressing down the elastic thread, the elastic thread is easily broken. A sinker triangle for a horizontal knitting machine is specially proposed to solve the above problems. Utility Model Content

[0042] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installation", "connection" and "connection" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.
[0043] The utility model embodiment provides a sinker triangle for a flat knitting machine, such as Figure 1-2 As shown, it includes a mounting plate 2 and a triangular plate 1, a channel 3 is provided between the triangular plate 1 and the mounting plate 2 for the mounting end of the sinker to pass through, an upper track curve and a lower track curve are provided on the triangular plate 1, and a plurality of left weaving segments and a plurality of right weaving segments are provided on the upper track curve and the lower track curve, and the plurality of left weaving segments form a left main yarn weaving segment 5 and a left elastic weaving segment 4, and the plurality of right weaving segments form a right main yarn weaving segment 6. When the glove machine head moves to the left, the left main yarn weaving segment 5 and the left elastic weaving segment 4 control the sinker to run in the channel 3 to cooperate with the knitting needles to complete the weaving of the main yarn and the elastic line, and when the machine head moves to the right to reset, the sinker is controlled by the right weaving line segment to run in the channel 3 to cooperate with the knitting needles to complete the weaving of the main yarn. The basis for determining the above left and right directions is Figure 1 On the left and right sides of the paper.
[0044] like Figure 3-4As shown, in order to reduce the probability of the elastic thread being cut, thereby ensuring the stability of the elastic thread during the weaving process, in addition to the fixed head, the upper end surface of the triangle plate 1 is also provided with a first active head 7, wherein the first active head 7 is parallel to the fixed head front and back and is located on the left side of the left main yarn weaving section 5, and cooperates with the triangle plate 1 to weave the elastic thread, wherein the first active head 7 has a first state that causes the sinker to be lifted and a second state that does not change the movement trajectory of the sinker; specifically, the high and low sinkers are relative to the triangle plate 1 from In the process of passing through the fixed head and the first active head 7 from right to left, the first active head 7 is always in the first state, the fixed head and the first active head 7 respectively lift the high-position sinker and the low-position sinker, and the lifting heights are the same, and then the side wall of the triangle plate 1 makes the two of them drop to flatten the woven fabric, so that for the double-sided sinker triangle, it does not affect the double-sided weaving effect; in the process of the high and low sinkers passing through the fixed head and the first active head 7 from left to right relative to the triangle plate 1, the fixed head lifts the high sinker. Then the triangle plate 1 makes the high sinker drop down and insert the rubber line, and at the same time the low sinker makes the first active head 7 rotate rightward from the first state to the second state, so that the low sinker moves rightward along the original height direction, that is, in the process of weaving the rubber line, the high sinker is first lifted and then dropped by the action of the fixed head and the triangle plate 1, while the low sinker continues to move rightward along the original height direction, and finally only the high sinker moves the rubber line, and the rubber line is subsequently pressed, and the rubber line is wound around the top of the low sinker. However, the low-position sinker does not act on the elastic cord. Compared with the full-high (full-low) sinker acting on the elastic cord at the same time, the insertion points of the elastic cord are reduced under the above operation, and the probability of the elastic cord being broken is reduced. Moreover, under the requirement of "continuous" elastic cord, after the gloves are formed, the elastic cord woven into the cuff can be reduced, the size is smaller, the qualified rate is higher, and the elasticity is better. However, the cuff formed by the full-high (full-low) sinker simultaneously acting may cause the cuff width to be insufficiently retracted, and the size is too large and does not meet the standard because more elastic cord is woven into it. Specifically, the high-position sinker and the low-position sinker are set in "two intervals or one interval". In summary, a rotatable first active head 7 is set, which not only reduces the insertion position of the elastic cord during the weaving process of the elastic cord, reduces the probability of being broken, ensures the weaving process of the elastic cord, and does not affect the flattening of the fabric after weaving from right to left, ensuring the flattening effect of the sinker triangle and the sinker double-sided weaving.
[0045] Specifically, the upper end surface of the triangle plate 1 is provided with a first mounting groove 101 which is connected with the channel 3, and the lower part of the first movable head 7 is installed in the first mounting groove 101 through the first rotating shaft, and in the first state, the upper part of the first movable head 7 protrudes outside the first mounting groove 101 and contacts with the left groove wall of the first mounting groove 101, and the first mounting groove 101 has a space for the first movable head 7 to rotate to the right, and the height of the first movable head 7 is the same as that of the fixed head. In the second state, the first movable head 7 is located below the low-position sinker, so as not to interfere with the movement trajectory of the low-position sinker. Therefore, when the low-position sinker moves from right to left relative to the triangle plate 1, the first movable head 7 is always in the first state under the action of the low-position sinker, and plays the same role as the fixed head, so that the low-position sinker is lifted, and then descends under the action of the triangle plate 1 to flatten the fabric; so when the low-position sinker moves relative to the triangle plate 1 from right to left, the first movable head 7 is always in the first state under the action of the low-position sinker, and plays the same role as the fixed head, so that the low-position sinker is lifted, and then descends under the action of the triangle plate 1 to flatten the fabric; When the triangle plate 1 moves from right to left, the first active head 7 can be rotated to the right under the action of the low-position sinker, because the first mounting groove 101 has a rotation space, and rotates from the first state to the second state, and the original height direction of the low-position sinker moves to the right; and in order to facilitate the use of the second active head 9, a first reset member 8 is also arranged on the second rotating shaft, and the first reset member 8 is a torsion spring, and the left groove wall of the corresponding first mounting groove 101 is provided with a first limiting groove 102, and the protruding end of the torsion spring is located in the first limiting groove 102, so that during use, when the low-position sinker moves from right to left relative to the triangle plate 1 in the channel 3, the low-position sinker forces the second active head 9 to rotate to the right from the first state to the second state, and once the low-position sinker passes, the second active head 9 will be reset to the first state from the second state due to the action of the torsion spring; and the installation structure of the above-mentioned first active head 7 is simple and low in cost.
[0046] Specifically, the left elastic braiding section 4 includes a left elastic braiding section 1 41 for lifting the sinker and a left elastic braiding section 2 42 for lowering the sinker. The sinker is controlled by the left elastic braiding section 1 41 and the left elastic braiding section 2 42 to complete the action of pressing and pulling the elastic line. The right main yarn flattening section includes a right main yarn flattening section 65 for lifting the sinker and a left main yarn flattening section 2 56 for lowering the sinker, so as to flatten the fabric. Specifically, the left elastic braiding section 41 and the right main yarn flattening section 65 are respectively arranged on the left and right side walls of the upper end of the fixed head, and are provided for the high position sinker ( Figure 4 and Figure 6 The mark in the middle is H) walking, the right main yarn flattening second section 66 and the left elastic braiding second section 42 are respectively arranged on the left and right side walls of the lower end concave portion of the triangle plate 1; the upper part of the first active head 7 is provided with a low-position sinker ( Figure 4 and Figure 6 The second braiding section marked in the middle is L), and the second braiding section includes a first left braiding section 71 and a first right braiding section 72, which are respectively located on the left and right side walls of the upper end of the first active head 7 and are used for the low-position sinker to travel; Figure 3-4As shown, the machine head moves to the right, and the sinker moves from right to left relative to the triangle plate 1 in the channel 3, first passing through the right main yarn weaving section 6, and then passing through the first active head 7 and the fixed head, because the first active head 7 is in the first state and contacts with the left groove wall of the installation groove, the low sinker cannot force the first active head 7 to rotate to the left, and the low sinker moves and rises along the first right weaving section 72, and the high sinker moves along the right main yarn leveling section 65, wherein the height of the right main yarn leveling section 65 is flush with the height of the first right weaving section 72, so that the high and low sinkers have the same trajectory from right to left when weaving the main yarn, and then the high and low sinkers move and descend along the right main yarn leveling second section 66 together to ensure the consistency of the main yarn weaving leveling stage; as shown Figure 5-6 As shown, the machine head moves to the left, and the sinker moves from left to right relative to the triangle plate 1 in the channel 3. Since there is a rotation space on the right side of the first mounting groove 101, the low sinker will move along the first left weaving section 71, and make the lower part of the first active head 7 rotate to the right in the first mounting groove 101. The first active head 7 rotates from the first state to the second state, so that the low sinker continues to move along the original height, and the high sinker moves along the left elastic weaving section 41 and is lifted, so that the entire first left weaving section 71 is lower than the left elastic weaving section 41, and then moves down along the left elastic weaving section 2 42. Since the elastic line will only be pressed and stretched by the lifted high sinker, finally only the high sinker inserts the elastic line and presses the elastic line, and the elastic line bypasses from above the low sinker, and the low sinker does not act on the elastic line. Then the sinker continues to move along the left main yarn weaving section 5 and cooperates with the knitting needle to weave the main yarn.
[0047] Of course, preferably, when the first active head 7 is in the first state, the first active head 7 needs to be located directly in front of the fixed head, and the curvature of the weaving surface set on the right side wall of the first active head 7 and the weaving surface set on the right side wall of the fixed head at the corresponding height are the same, so as to ensure double-sided weaving and the consistency of the movement of the sinker in the fabric flattening stage after weaving from right to left.
[0048] In order to facilitate the installation of the first movable head 7, a mounting hole connected to the first mounting groove 101 is provided on the rear side wall of the triangular plate 1. A sealing plate 11 is installed in the mounting hole through bolts. The sealing plate 11 is used to seal the mounting hole. At the same time, the first rotating shaft is rotatably installed on the sealing plate 11.
[0049] When the sinker triangle is double-sidedly woven, in order to ensure the consistency of the double-sided weaving, the sinker plate is provided with two weaving line segments in the left main yarn weaving segment 5 and the right main yarn weaving segment 6 provided on the triangle bottom plate, so that the sinker plate is first pre-dropped to a certain height, and then dropped to the weaving height to perform the coil forming operation. However, during the weaving process of the elastic thread, the elastic thread is inserted before the yarn coil, that is, before the sinker plate acts on the left main yarn weaving segment 5, the sinker plate inserted with the elastic thread will continue to drop due to the effect of the second downward pressure on the weaving line segment. , so that the height of the sinker is too low, and the elastic rubber band is easily broken. In order to solve the above problem, preferably, the right main yarn weaving section 6 includes a right main yarn weaving sub-section that makes the sinker drop once and a right main yarn weaving third section 63 that makes the sinker drop twice. A rotatable second active head 9 is provided on the mounting plate 2. The right main yarn weaving third section 63 is arranged on the lower side wall of the second active head 9. The second active head 9 has a first state that makes the sinker drop and a second state that does not change the movement trajectory of the sinker. Specifically, Figure 3-4 As shown, the machine head moves to the right, and during the process of the sinker moving from right to left relative to the triangle plate 1, the second active head 9 is in the first state, and the sinker first moves along the right main yarn weaving section 6 to make the sinker drop for the first time. Since the left side wall of the second active head 9 abuts against the left side wall of the second mounting groove 21, the sinker then moves along the lower side wall of the second active head 9 to make the sinker drop for the second time to weave the main yarn, and in the above process, the second active head 9 is in the first state; during the process of the sinker moving from left to right relative to the triangle plate 1, as shown in FIG. Figure 5-6 As shown, the machine head moves to the left, the high and low position sinkers pass through the fixed head and the first active head 7, and then the sinkers (high and low position sinkers) contact the second active head 9, so that the second active head 9 rotates rightward from the first state to the second state, and at the same time, the sinkers move along the left main yarn weaving section 5, so that the sinkers are lowered for the second time, and the movement trajectory of the sinkers is not changed to weave the main yarn; it can be seen from the above that the design of the first active head 7 can completely carry out double-sided weaving of the fabric, and in the process of weaving the elastic thread, that is, the In the process of the sinker moving from left to right relative to the triangle plate 1, the high sinker for inserting the rubber thread will make the second active head 9 move rightward and rotate rightward to a certain height. The lower side wall of the second active head 9 will not act on the high sinker and will not interfere with the original movement trajectory of the high sinker, so that the high sinker will not drop again before weaving the left main yarn section 5, avoiding the excessive downward pressure distance of the rubber thread and the probability of the rubber thread being broken, further reducing the probability of the rubber thread being broken, and further improving the stability of the rubber thread weaving.
[0050] Specifically, the mounting plate 2 is provided with a second mounting groove 21 connected with the channel 3, and the upper part of the second movable head 9 is rotatably arranged in the second mounting groove 21 through the second rotating shaft. When the second movable head 9 is in the first state, the second movable head 9 contacts the left groove wall of the second mounting groove 21, and the right side of the second mounting groove 21 has a space for the second movable head 9 to rotate to the right. In the second state, the second movable head 9 is located above the sinker; specifically, in the process of the sinker moving from right to left relative to the triangular plate 1, under the action of the sinker, the sinker forces the left side wall of the second movable head 9 to contact the left groove wall of the second mounting groove 21. The wall is in contact with each other, so that after the raw piece has walked along the right main yarn weaving section 6, the raw piece will descend once and then continue to descend for the second time along the lower side wall of the second active head 9; in the process of the raw piece moving from left to right relative to the triangle plate 1, after the high and low position raw pieces pass through the fixed head and the first active head 7, the high position raw piece will make the upper part of the second active head 9 move rightward in the second mounting groove 21 until the second active head 9 moves from the first state to the second state, thereby not interfering with the movement trajectory of the original high position raw piece, and then move along the left main yarn weaving section 5, so that the raw piece will descend for the second time.
[0051] Specifically, in order to facilitate the use of the second active head 9, a second reset member 10 is further provided on the second rotating shaft, and the second reset member 10 is a torsion spring. The corresponding left groove wall of the second mounting groove 21 is provided with a second limiting groove 22, and the protruding end of the torsion spring is located in the second limiting groove 22. Therefore, during use, when the sinker moves from right to left relative to the triangular plate 1 in the channel 3, the sinker forces the second active head 9 to rotate rightward from the first state to the second state. Once the sinker passes, due to the action of the torsion spring, the second active head 9 will be reset to the first state from the second state.
[0052] Specifically, Figure 1 As shown, the left main yarn braiding section 5 includes a left main yarn braiding section 1 51, a left main yarn braiding section 2 52 and a left main yarn braiding section 3 53 arranged from left to right, the right main yarn braiding section 6 includes a right main yarn braiding section 1 61 and a right main yarn braiding section 2 62 arranged from right to left, and the lower side wall of the second active head 9 has a right main yarn braiding section 3 63; wherein the active head is in the first state, the right main yarn braiding section 3 63 is located on the left side of the right main yarn braiding section 2 62, as shown in FIG. Figure 3-4 As shown, the machine head moves to the right, and the sinker moves from right to left relative to the triangle plate 1. The second active head 9 is in the first state. The sinker first weaves a section 61 along the right main yarn to lift the sinker, and then weaves the second section 62 and the third section 63 along the right main yarn to lower the sinker for the second time, so as to weave the main yarn from right to left. Figure 5-6As shown, the machine head moves to the left, and during the process of the sinker moving from left to right relative to the triangle plate 1, the sinker first weaves a section 51 along the left main yarn to lift the sinker, and then weaves the sinker along the left main yarn second section 52 and the left main yarn third section 53 to lower the sinker for a second time, so as to weave the main yarn from left to right, and while the sinker moves to the right along the left main yarn weaving section 51, the upper part of the second active head 9 moves to the right in the second mounting groove 21, so that the sinker moves to the right from the first state to the second state relative to the triangle plate 1, without affecting the movement trajectory of the high-position sinker, and after the sinker passes through the second active head 9, the second active head 9 is restored to the first state under the action of the second reset member 10; it can be seen that in the sinker triangle capable of double-sided weaving, the lower side wall of the second active head 9 acts as the right main yarn weaving third section 63, which only works when the main yarn is weaved to the right, and does not act on the sinker under the action of the elastic thread weaving.
[0053] It should be noted that the second active head 9 is located between the main yarn braiding section and the elastic yarn braiding section. As for the left elastic braiding section 4, the left main yarn braiding section 5, the right main yarn braiding section 6, etc., the left and the right are only relative to each other.

Specifically, as Figure 1 As shown, the upper track curve is provided with a plurality of convex parts, and the lower track curve is provided with a plurality of concave parts, wherein a left elastic band braiding section 41, a left main yarn braiding section 51, a left main yarn braiding section 44, and a left main yarn flattening section 55 are located on the left side of each convex part, a left elastic band braiding section 2 42, a left main yarn braiding section 2 52, a left main yarn braiding section 3 53, and a left main yarn flattening section 2 56 are located on the right side of each inner concave part, and a left elastic band braiding section 41, a left elastic band braiding section 2 42, a left main yarn braiding section 51, a left main yarn braiding section 2 52, and a left main yarn flattening section 3 56 are located on the right side of each inner concave part. 53, the left main yarn weaving four sections 54, the left main yarn flattening one section 55 and the left main yarn flattening two sections 56 are arranged from left to right, and correspondingly, the right main yarn weaving one section 61, the right main yarn weaving four sections 64, the right main yarn flattening one section 65 are located on the right side of each convex part, the right main yarn weaving two sections 62 and the right main yarn flattening two sections 66 are located on the left side of each concave part, and the right main yarn weaving three sections 63 are located below the second active head 9, and the first right weaving section 72 arranged on the right side wall of the first active head 7 also participates in the same function as the right main yarn flattening one section 65, as shown in FIG. Figure 1As shown, in the first state, the right main yarn weaving section 61, the right main yarn weaving section 2 62, the right main yarn weaving section 3 63, the right main yarn weaving section 4 64, the right main yarn flattening section 1 65 and the right main yarn flattening section 2 66 are arranged from right to left, and the first right weaving section 72 is located directly in front of the right main yarn flattening section 1 65.
