Technical Field
[0001] This utility model relates to the field of knitting technology, specifically to a knitting machine head and a flat knitting machine with a sinker plate for pressing the float yarn. Background Technology
[0002] Existing flat knitting machines mainly include a needle plate and a knitting head. The needle plate has several sinker slots, and each sinker slot contains a rotatable sinker. The knitting head is equipped with multiple sets of sinker movable triangles for driving the sinker to close and open. There is a normally open channel between adjacent sinker movable triangles. Each set of sinker movable triangles consists of a left movable triangle and a right movable triangle. During the start-up of the flat knitting machine, one of the left movable triangles is normally closed and the other is normally open. The normally closed triangle is used to drive the sinker to close and press the yarn on both sides of the needle plate, while the normally open triangle does not press the sinker. The sinker is in a relaxed state, and the yarn is also in a relaxed state.
[0003] The existing flat knitting machine uses a knitting head with multiple sets of movable sinker triangles to drive the sinker. This technology works well for single-thread knitting, but for knitted products with jacquard requirements, it is prone to problems where the needle cannot catch the yarn, leading to missed stitches and loops in the knitted product. Utility Model Content
[0004] The purpose of this invention is to provide a knitting machine head and a flat knitting machine with a sinker plate pressing float yarn triangle. By adding a sinker plate pressing float yarn triangle between adjacent sinker plate movable triangle assemblies on the knitting machine head, the length of the float yarn is greatly shortened. The float yarn is then pressed down by the sinker plate pressing float yarn triangle near the knitting needle, which solves the problem that the pressing positions of adjacent sinker plate movable triangle assemblies on existing knitting machine heads are far apart, making it easy for the knitting needle to fail to hook the float yarn, thus affecting the quality and effect of the knitted products.
[0005] A knitting machine head with sinker plate pressing and floating yarn triangles includes sinker plate movable triangle components and sinker plate pressing and floating yarn triangles mounted on the head frame. There are two or more sets of sinker plate movable triangle components, which are distributed at intervals on the head frame. A sinker plate pressing and floating yarn triangle is provided between each two adjacent sets of sinker plate movable triangle components. Both the sinker plate movable triangle components and the sinker plate pressing and floating yarn triangles are used to drive the sinker plates on both sides to gather and press the floating yarn.
[0006] The knitting machine head described above features two or more sets of spaced-apart movable triangular sinker assemblies on the head frame, with sinker-pressing float triangles positioned between adjacent sets of these assemblies. This solution replaces the normally open structural components between adjacent movable triangular sinker assemblies in existing knitting machine heads, achieving this without altering the overall structure of the existing knitting machine head. The knitting machine head is ingeniously conceived, simple in structure, and easy to manufacture, install, and operate. Meanwhile, this technical solution replaces the normally open structural component between adjacent sinker movable triangle components in the existing knitting machine head with the sinker pressing float triangle in this solution, which greatly shortens the length of the float. This allows the float to be pressed down by the sinker pressing float triangle near the knitting needle, solving the problem that the driving position distance between adjacent sinker movable triangle groups in the existing knitting machine head is too far, which easily leads to the knitting needle not being able to hook the float, affecting knitting efficiency, product quality and effect. This technical solution can achieve single-sided jacquard knitting as well as double-sided jacquard knitting. Single-sided jacquard knitting will not have jacquard thread marks on the back, and double-sided jacquard knitting can achieve different colors or patterns on both sides, greatly improving the efficiency and quality of knitted products.
[0007] Furthermore, each set of settling plate movable triangular components includes a settling plate triangular assembly fixing bracket and a settling plate triangular base plate. The settling plate triangular base plate is fixed on the settling plate triangular assembly fixing bracket. A settling plate movable triangular drive plate is provided behind the settling plate triangular base plate, and a settling plate movable triangle is provided in front of the settling plate triangular base plate. The back of the settling plate movable triangle is connected to the settling plate movable triangular drive plate.
[0008] In the above technical solution, the setting of the settling plate triangular assembly fixing bracket is used to install the settling plate triangular base plate, so that the settling plate triangular base plate is installed on the knitting machine head frame through the settling plate triangular assembly fixing bracket; the setting of the settling plate triangular base plate is used to install and support the settling plate movable triangular; the setting of the settling plate movable triangular drive plate behind the settling plate triangular base plate is used to connect the settling plate movable triangular and drive the settling plate movable triangular to move, so that the settling plate movable triangular is driven by the settling plate movable triangular drive plate to drive the settling plate to retract and realize the pressing action; in this technical solution, the settling plate movable triangular drive plate is provided with a forward protruding connecting block, and the settling plate triangular base plate is provided with a movable space for the connecting block to reciprocate, the connecting block passes through the movable space and connects with the settling plate movable triangular, driving the settling plate movable triangular to move.
[0009] Furthermore, each set of sinker movable triangle components includes two sinker movable triangles. During the operation of the knitting machine head, one sinker movable triangle in each set of sinker movable triangle components is used to drive the sinker to move and press the yarn, while the other sinker movable triangle relaxes the sinker to loosen the yarn.
[0010] In the above technical solution, in the sinker movable triangle assembly, only one of the two sinker movable triangles drives the sinker to move and press the yarn during the knitting machine head's movement in one direction, while the other sinker movable triangle is normally open and used to relax the sinker to allow the yarn to be in a relaxed state. During the knitting machine head's reciprocating movement, the sinker movable triangle that originally drove the sinker becomes normally open and is used to relax the sinker, thereby allowing the yarn to be in a relaxed state. The normally open sinker movable triangle is placed in a position that can drive the sinker to move and press the yarn. This arrangement of two sinker movable triangles in each group allows the knitting machine head to achieve reciprocating motion without changing the triangles.
[0011] Furthermore, the settling plate pressure line triangle is located in the middle of one side of the settling plate and has a settling plate floating channel that runs through the settling plate pressure line triangle, which is used to drive the settling plate on the needle plate to float and reciprocate.
[0012] In the above technical solution, the floating channel of the sinker on the sinker-supported float triangle is used to accommodate the sinker and allow it to float along the channel. This floating channel design allows the sinker to first retract and press the float, then release it, allowing both the sinker and float to return to their original positions. After the float returns, the sinker is driven to retract and press the float again. This reciprocating action of retracting, releasing, and retracting the float ensures that any float that might have been missed or incompletely pressed during the previous sinker retraction and pressing operation returns to its original position before another retraction and pressing operation is performed. This ensures no missed pressing and prevents the needle from snagging the yarn, thus ensuring the quality and effect of the knitting.
[0013] Furthermore, the two ends of the settling plate floating channel are guide ends, and the middle of the settling plate floating channel is a pressing part, which enables the settling plate to achieve floating reciprocating pressing of the floating line.
[0014] In the above technical solution, both ends of the sinker floating channel are set as guide ends. During the operation of the knitting machine head, the guide ends can guide the sinker, allowing it to quickly enter the sinker floating channel. Within the sinker floating channel, the sinker performs actions such as closing and pressing the float yarn, releasing the float yarn, and then closing and pressing the float yarn again before exiting the sinker floating yarn pressing channel through the guide ends to enter the next station. The middle of the sinker floating channel is set as the middle pressing section, enabling the sinker to perform floating reciprocating pressing of the float yarn. This reciprocating pressing operation, where the sinker first closes and presses the float yarn, then releases it to return it to its original position, and then closes and presses the float yarn again, ensures that any float yarn that may have been missed or incompletely pressed during the previous sinker pressing operation returns to its original position before the next pressing operation is performed. This ensures no missed pressing and prevents the needle from snagging the yarn, thus ensuring the knitting quality and effect.
[0015] Furthermore, the pressure line section has a wave-shaped design, which allows the sinker to reciprocate and press the floating line at least twice.
[0016] In the above technical solution, the pressure section is preferably designed with a wave-like shape, ensuring that the settling plate reciprocates and presses the floating line at least twice, thus guaranteeing the floating line pressure. Specifically, ensuring that the settling plate presses the floating line at least twice gives any missed pressure a chance to return and allow the settling plate to press the floating line again. Moreover, the wave-like design of the pressure section makes it easier for the settling plate to pass through the channel where the pressure section is located, effectively ensuring smooth operation of the equipment and improving its operating efficiency.
[0017] As one of the preferred solutions to the above technical solution, the pressure part is configured with an "M" structure, including a pressure position L1 and a pressure position L2, and there is a concave area between the pressure position L1 and the pressure position L2.
[0018] In this technical solution, the "M" structure's pressure section forms two pressure points: L1 and L2. A concave area is formed between L1 and L2. When the knitting machine head is running, L1 first contacts the corresponding sinker, causing the sinker to close and press down the float. Floats not pressed down by the sinker enter the concave area between L1 and L2. This concave area is used to release the sinker and allow the float to return to its original position. By setting a concave area between adjacent pressure points, the sinker floating channel drives the sinker to close and press down the float during operation. After the sinker closes and presses down the float, it releases and allows the float to return to its original position. This ensures that when the next pressure point of the sinker floating channel is reached, it drives the sinker to close and press down the float again. This allows the small amount of float that was missed in the previous sinker closure to be pressed down again, preparing for the needle to catch the thread and ensuring that the needle does not miss the thread, thereby ensuring the knitting quality and effect. The concave area setting ensures that the float yarn is not pressed by the sinker at the corresponding position and returns to its free state. As the knitting machine head moves, the L2 pressing position moves forward, driving the sinker to move and close again to press the float yarn. This allows the small amount of float yarn that was missed by the sinker driven by the L1 pressing position to be pressed again by the sinker driven by the L2 pressing position after returning to its original position. This ensures that all float yarns enter the needle area under the pressing of the sinker and are then hooked by the needles to knit the product.
[0019] As a preferred embodiment of the above technical solution, the pressure part is a "connected double M" structure, including pressure position L1, pressure position L2 and pressure position L3, and the area between pressure position L1 and pressure position L2, and the area between pressure position L2 and pressure position L3 are concave areas.
[0020] In this technical solution, the "one-piece double M" structure's pressing section forms three pressing positions: L1, L2, and L3. Its working principle is the same as the pressing section of the "M" structure. The difference is that, compared to the "M" structure's pressing section, it includes an additional floating thread return and re-pressing action. Whether to use the "M" structure's pressing section or the "one-piece double M" structure's pressing section depends on the specific operating performance of the knitting machine.
[0021] Furthermore, the settling plate pressure line triangle is provided with a fixing part, which is located above or below the settling plate channel. The fixing part has one or more mounting holes, and the settling plate pressure line triangle is mounted on the machine head frame at the mounting holes.
[0022] In the above technical solution, the setting of the fixing part on the settling plate pressure line triangle is used to install and fix the settling plate pressure line triangle on the head frame. Specifically, the settling plate pressure line triangle can be fixed on the head frame by the fixing part at the mounting hole, or the settling plate pressure line triangle can be detachably installed on the head frame by the adjusting part at the mounting hole.
[0023] A flat knitting machine includes a needle plate assembly, which comprises two needle plates arranged at opposite inclinations. Each needle plate has a plurality of sinker receiving grooves at its end, and sinkers are rotatably connected within these grooves. Above the needle plates is a yarn feeding assembly fixed to the flat knitting machine and a knitting head with sinker-loaded cams that can reciprocate along the direction of the needle plates. The movable sinker cam assembly in the knitting head drives the sinkers to press the yarn, and the sinker-loaded cam in the knitting head drives the sinkers to reciprocate in a floating manner to press the yarn.
[0024] In the above technical solution, the needle plate of the flat knitting machine is provided with several rotatable sinkers. Above the needle plate is a knitting head that moves along the length of the needle plate. The knitting head is provided with two or more sets of sinker movable triangular assemblies, and sinker pressing and floating yarn triangles are set between adjacent sets of sinker movable triangular assemblies. Each set of sinker movable triangular assemblies includes a first sinker movable triangle and a second sinker movable triangle. The first and second sinker movable triangles are staggered in front and behind during operation. Different sinker movable triangles drive the sinker movement when the knitting head moves back and forth. That is, in each set of sinker movable triangular assemblies, one of the first and second sinker movable triangles is in working state to drive the sinker movement to realize the pressing operation, while the other is in a normally open state. The existing technology, which uses a sinker to release the float and return it to its original position, employs a two-triangle configuration in each group. This results in a significant distance between the sinker triangle in the first group and the one in the second group, causing the float to be far from the knitting position of the yarn at the pressing position. Consequently, the angle between the float and the needle plate is small, preventing the needle from hooking the yarn and leading to issues like loops and / or loose threads in the knitted product. This new technology addresses this by adding a sinker triangle between adjacent groups of sinker triangles. This triangle increases the driving position of the sinker, effectively shortening the float length and ensuring the needle can hook it, thus guaranteeing the quality and effect of the knitted product.
[0025] Furthermore, the yarn feeding assembly includes a yarn nozzle, and the distance between the L1 pressing position on the sinker pressing tassel and the yarn nozzle is greater than the distance between the L2 pressing position and the yarn nozzle. In the sinker movable tassel assembly, the distance between the sinker movable tassel used to drive the sinker movement and the yarn nozzle is greater than the distance between the L1 pressing position on the sinker pressing tassel and the yarn nozzle.
[0026] In the above technical solution, the movable triangle component of the sinker is positioned away from the yarn feeder relative to the sinker pressing float triangle, and the L1 pressing position in the sinker pressing float triangle is positioned away from the yarn feeder relative to the L2 pressing position. This allows the movable triangle component of the sinker to first contact the sinker and drive the sinker to move to press the float yarn, and then the L1 pressing position and L2 pressing position in the sinker pressing float triangle press the float yarn in sequence, ensuring the pressing effect of the float yarn.
[0027] Compared with the prior art, the knitting machine head and flat knitting machine with sinker plate pressing float triangle of this utility model have the following advantages:
[0028] First, the design is ingenious. This utility model adds a sinker plate pressure float triangle to the traditional knitting machine head and places the sinker plate pressure float triangle between adjacent sinker plate movable triangle components. It replaces the normally open structural component between adjacent sinker plate movable triangle components in the existing knitting machine head. It can be achieved by replacing only one part of the existing knitting machine head without changing the overall structure of the existing knitting machine head. The overall design of this knitting machine head is ingenious, and the structure is simple, easy to process, install and operate.
[0029] Secondly, it offers high knitting efficiency and excellent knitting quality and effect. This invention replaces the normally open structural component between adjacent sinker cam assemblies in existing knitting machine heads with the sinker cam pressing float cam in this solution. A float pressing position is added between the two sets of sinker cam assemblies, significantly shortening the float length. This allows the float to be pressed down near the needle by the sinker cam pressing float cam, solving the problem of the existing knitting machine heads having a large distance between the driving positions of adjacent sinker cam assemblies, which easily leads to the needle not being able to hook the float, affecting knitting efficiency, product quality, and effect. This invention can not only perform single-sided jacquard knitting but also double-sided jacquard knitting. Single-sided jacquard knitting will not leave jacquard thread marks on the back, while double-sided jacquard knitting can achieve different colors or patterns on both sides, greatly improving the efficiency and quality of knitted products.

Detailed Implementation
[0038] Reference Figure 1 and Figure 2According to a non-limiting embodiment of this utility model, a knitting machine head with a sinker plate pressing and floating line triangle 130 includes a sinker plate triangle structure 100 mounted on the head frame (not shown in the figure). The sinker plate triangle structure 100 includes a sinker plate movable triangle assembly 120 and a sinker plate pressing and floating line triangle 130. A left reset triangle 110 and a right reset triangle 140 are respectively provided on the outer side of the sinker plate movable triangle assembly 120 located at both ends. There are two or more sets of sinker plate movable triangle assemblies 120, which are distributed at intervals on the head frame. A sinker plate pressing and floating line triangle 130 is provided between each two adjacent sets of sinker plate movable triangle assemblies 120. Both the sinker plate movable triangle assembly 120 and the sinker plate pressing and floating line triangle 130 are used to drive the sinker plates on the needle plates 210 on both sides to close and press and float the thread. In this embodiment, the left reset triangle 110 and right reset triangle 140 of the knitting machine head are used to reset the sinker when entering and exiting the sinker triangle structure 100, facilitating subsequent pressing operations. In this embodiment, by setting two or more sets of spaced sinker movable triangle components 120 on the machine head frame, and setting sinker pressing and floating triangles 130 between adjacent sets of sinker movable triangle components 120, the sinker pressing and floating triangles 130 are placed between adjacent sinker movable triangle components 120 to replace the normally open structural components between adjacent sinker movable triangle components 120 in the existing knitting machine head. This can be achieved by replacing only one component in the existing knitting machine head without changing the overall structure of the existing knitting machine head. The overall design of this knitting machine head is ingenious, and the structure is simple, easy to process, install and operate. Meanwhile, the technical solution of this embodiment replaces the normally open structural component between adjacent sinker movable triangle components 120 in the existing knitting machine head with the sinker pressing float triangle 130 in this solution, which greatly shortens the length of the float. This allows the float to be pressed by the sinker near the needle by the pressing float triangle 130, solving the problem that the driving position distance between adjacent sinker movable triangle components 120 in the existing knitting machine head is too far, which easily leads to the knitting needle not being able to hook the float, affecting knitting efficiency, product quality and effect. The knitting machine head of this embodiment can be used on a flat knitting machine to realize single-sided jacquard knitting as well as double-sided jacquard knitting. Single-sided jacquard knitting will not have jacquard thread marks on the back, and double-sided jacquard knitting can realize different colors or patterns on both sides, which greatly improves the efficiency and quality of knitted products.
[0039] Reference Figure 1 and Figure 2In a non-limiting embodiment of this utility model, each set of settling plate movable triangular assembly 120 includes a settling plate triangular assembly fixing bracket 121 and a settling plate triangular base plate 122. The settling plate triangular base plate 122 is fixed on the settling plate triangular assembly fixing bracket 121. A settling plate movable triangular drive component (not shown in the figure) is provided behind the settling plate triangular base plate 122. Settling plate movable triangles 124 and 125 are provided in front of the settling plate triangular base plate 122. Each settling plate movable triangle 124 and 125 is provided with a settling plate channel 126. The back of the settling plate movable triangles 124 and 125 is connected to the settling plate movable triangular drive component. In this embodiment, the settling plate triangular assembly fixing bracket 121 is used to install the settling plate triangular base plate 122, so that the settling plate triangular base plate 122 is installed onto the knitting machine head frame via the settling plate triangular assembly fixing bracket 121; the settling plate triangular base plate 122 is used to install and support the settling plate movable triangles 124 and 125; the settling plate movable triangle driving component behind the settling plate triangular base plate 122 is used to connect the settling plate movable triangles 124 and 125 and drive the settling plate movable triangles. The movement of 124 and 125 causes the settling plate movable triangles 124 and 125 to retract under the drive of the settling plate movable triangle drive component, thereby achieving the pressing action. In this embodiment, the settling plate movable triangle drive component is provided with a forward-protruding connecting block 127, and the settling plate triangle base plate 122 is provided with a movable space 123 for the connecting block 127 to reciprocate. The connecting block 127 passes through the movable space 123 and connects with the settling plate movable triangles 124 and 125, thereby driving the settling plate movable triangles 124 and 125 to move.
[0040] Reference Figure 1 , Figure 2 and Figure 7 In a non-limiting embodiment of this utility model, each set of movable sinker triangle components 120 includes two movable sinker triangles 124 and 125. During the operation of the knitting machine head, one movable sinker triangle in each set of movable sinker triangle components drives the sinker to move and press the yarn, while the other movable sinker triangle relaxes the sinker to loosen the yarn. In this embodiment, when the knitting machine head moves in one direction, only one movable sinker triangle 124 or 125 drives the sinker to move and press the yarn, while the other movable sinker triangle is normally open and used to relax the sinker to allow the yarn to be in a relaxed state. Specifically, this implementation example Figure 7 As shown, sink The settling plate is relaxed by the movable triangle 125, while the settling plate is driven by the movable triangle 124 to move and press the floating line.During the reciprocating motion of the knitting machine head, the movable triangle of the sinker, which originally drove the sinker to move, becomes normally open to relax the sinker and thus relax the yarn. The normally open movable triangle of the sinker is placed in a position that can drive the sinker to move and press the yarn. The setting of two movable triangles of the sinker in each group allows the knitting machine head to achieve reciprocating motion without changing the triangle.
[0041] Reference Figures 1 to 3 In a non-limiting embodiment of this utility model, the sinker plate pressure-float triangle 130 is located on one side of the sinker plate, and a sinker plate floating channel 131 is provided through the sinker plate pressure-float triangle 130 to drive the sinker plate on the needle plate 210 to reciprocate in a floating manner to press the float yarn. In this embodiment, the sinker plate floating channel 131 on the sinker plate pressure-float triangle 130 is used to accommodate the sinker plate and make the sinker plate float along the sinker plate floating channel 131. The design of the sinker plate floating channel 131 enables the sinker plate to form a reciprocating pressing-float yarn action of pressing, loosening, and pressing again. This ensures that when the sinker plate closes and presses the float yarn in the previous operation, some individual yarns that were not pressed may return to their original position first, and then the operation of closing and pressing the float yarn is performed again. This effectively reduces the possibility of single yarns being missed, ensures that there is no missed pressing, ensures that the needle does not miss the yarn, and thus ensures the knitting quality and effect.
[0042] Reference Figures 1 to 3 In a non-limiting embodiment of the present invention, the two ends of the settling plate floating channel 131 are guide ends, and the middle pressing part of the settling plate floating channel 131 enables the settling plate to achieve floating reciprocating pressing of the floating line. In this embodiment, the two ends of the sinker floating channel 131 are set as guide ends. During the operation of the knitting machine head, the guide ends can provide guidance for the sinker, allowing the sinker to quickly enter the sinker floating channel 131. The sinker then performs a series of actions within the sinker floating channel 131, including closing and pressing the float yarn, releasing the float yarn, and then closing and pressing the float yarn again before exiting the sinker floating channel through the guide ends to enter the next station. The middle of the sinker floating channel 131 is set as the pressing part, and the sinker performs a floating reciprocating pressing operation. This reciprocating pressing operation, where the sinker first closes and presses the float yarn, then releases the float yarn to return the yarn to its position, and then closes and presses the float yarn again, ensures that any float yarn that may have been missed or not fully pressed during the previous sinker pressing operation returns to its position before the next pressing operation is performed. This ensures that there is no missed pressing and that the knitting needle does not snag the yarn, thereby ensuring the knitting quality and effect.
[0043] Reference Figure 3 and Figure 4In a non-limiting embodiment of this utility model, the pressure line section is designed with a wave-like shape, allowing the settling plate to reciprocate and press the floating line at least twice. In this embodiment, the pressure line section is preferably designed with a wave-like shape, ensuring that the settling plate reciprocates and presses the floating line at least twice, thus guaranteeing the floating line pressure. Specifically, ensuring that the settling plate presses the floating line at least twice gives any missed pressure on the floating line at least one opportunity to return and allow the settling plate to press the floating line again. Moreover, the wave-like design of the pressure line section makes it easier for the settling plate to pass through the channel where the pressure line section is located, effectively ensuring smooth operation of the equipment and improving its operating efficiency.
[0044] like Figure 3 As shown, as one of the preferred solutions in this embodiment, the pressing part is configured with an "inverted M" structure, including pressing position L1 and pressing position L2, with a concave area between pressing position L1 and pressing position L2. In this embodiment, the pressing part configured with an "inverted M" structure forms two pressing positions, L1 and L2, and a concave area is formed between pressing position L1 and pressing position L2. When the knitting machine head runs above the needle plate 210, the sinker at pressing position L1 is driven inward by the sinker floating channel 131 to press the float yarn. Then, the drive on the sinker is released in the area between pressing position L1 and pressing position L2, and both the sinker and the float yarn return to their original positions. After the yarn returns to its original position, the sinker at pressing position L2 is driven inward by the sinker floating channel 131. The L2 pressure point of position 31 drives inward to press the float yarn again, so that the float yarn is first pressed by the sinker plate of the L1 pressure point, then relaxes and returns to its original position in the area between the L1 and L2 pressure points, and is pressed by the sinker plate of the L2 pressure point again. This causes any individual yarns that may have been missed by the sinker plate driven by the L1 pressure point to relax and return to their original position in the concave area between the L1 and L2 pressure points, and is then pressed by the sinker plate driven by the L2 pressure point again. This ensures that all float yarns enter the knitting needle area under the pressure of the sinker plate, and are then knitted by the knitting needle.
[0045] like Figure 4 As shown, as a second preferred embodiment, the pressing section is a "reverse double-M" structure, including pressing positions L1, L2, and L3. The areas between L1 and L2, and between L2 and L3, are concave regions. In this embodiment, the "reverse double-M" structure forms three pressing positions: L1, L2, and L3. The working principle of this embodiment is the same as that of the "reverse M" structure pressing section. The difference is that, compared to the "reverse M" structure, there is an additional yarn return and re-pressing action. Whether to use the "reverse M" or "reverse double-M" structure pressing section depends on the specific operating performance of the flat knitting machine.
[0046] Reference Figure 3 and Figure 4 The concave area is used to relax the sinker and allow the yarn to return to its original position. A concave area is formed between adjacent pressing positions so that after the sinker floating channel 131 drives the sinker to close and press the floating yarn during operation, the sinker enters the concave area on the sinker floating channel 131. Within this concave area, the sinker floating channel 131 no longer drives the sinker; that is, there is no external force driving the sinker to relax and return to a free state. Simultaneously, the yarn, after losing the pressing force of the sinker, also returns to a free floating state. This concave area ensures that when the next pressing position of the sinker floating channel 131 is reached, it again drives the sinker to close and press the floating yarn, allowing any small amount of floating yarn missed during the previous sinker closure to be pressed back down by the closed sinker, preparing for the needle to catch the yarn and ensuring that the needle does not miss any yarn, thereby ensuring the knitting quality and effect.
[0047] Reference Figure 3 and Figure 4 In a non-limiting embodiment of this utility model, the settling plate pressure-float triangle 130 is provided with a fixing part 132. The fixing part 132 is located above or below the settling plate floating channel 131. The fixing part 132 has one or more mounting holes, and the settling plate pressure-float triangle 130 is mounted on the head frame at the mounting holes. In this embodiment, the fixing part 132 on the settling plate pressure-float triangle 130 is located below the settling plate floating channel 131. Of course, in actual installation, the fixing part 132 can also be located above the settling plate floating channel 131, or above or below the settling plate floating channel 131, depending on the actual situation. The fixing principle is the same. The fixing part 132 is provided for installing and fixing the settling plate pressure float triangle 130 on the head frame. Specifically, the settling plate pressure float triangle 130 can be fixed on the head frame by the fixing part at the mounting hole, or the settling plate pressure float triangle 130 can be detachably installed on the head frame by the adjusting part at the mounting hole.
[0048] Reference Figures 5 to 7 According to a non-limiting embodiment of this utility model, a flat knitting machine includes two sets of needle plate assemblies 200 arranged in a triangular pattern on the machine table. Each needle plate assembly 200 includes a needle plate 210, and the end of each needle plate 210 is provided with a plurality of sinker receiving grooves (not shown in the figure). Sinkers 220 are rotatably connected within the sinker receiving grooves. The upper part of the needle plate assembly 200 is provided with... Figure 6 and Figure 7 The yarn feeding assembly 300 fixed on the flat knitting machine is shown, and as shown in the figure. Figures 1 to 4The knitting machine head shown includes a sinker-plate pressure-float triangle 130. The knitting machine head includes a sinker-plate triangle structure 100. A movable sinker-plate triangle component 120 in the sinker-plate triangle structure 100 drives the sinker-plate to press the yarn. The sinker-plate pressure-float triangle 130 in the knitting machine head drives the sinker-plate 220 to reciprocate in a floating manner to press the yarn. In this embodiment, the yarn feeding assembly 300 includes a yarn feeder 310. The distance from the L1 pressing position on the sinker-plate pressure-float triangle 130 to the yarn feeder 310 is greater than the distance from the L2 pressing position to the yarn feeder 310. The distance from the movable sinker-plate triangle 124 in the movable sinker-plate triangle component 120, which drives the sinker-plate movement, to the yarn feeder is greater than the distance from the L1 pressing position on the sinker-plate pressure-float triangle 130 to the yarn feeder 310. In this embodiment, as shown... Figure 7As shown, M2, the closest point to the yarn feeder, is the normal yarn feeding position. M1, outside of M2, is the normal loop forming and unwinding position. L2 and L1 are the two pressing positions of the sinker pressing cam 130, and a concave area is set between the L1 and L2 pressing positions. The sinker movable cam assembly 120 is set away from the yarn feeder 310 relative to the sinker pressing cam 130. The L1 pressing position in the sinker pressing cam 130 is set away from the yarn feeder 310 relative to the L2 pressing position. This ensures that when the knitting machine head is running above the needle plate 210, the sinker movable cam assembly 120 first contacts the sinker and drives the sinker to move to press the floating yarn. Then, the L1 and L2 pressing positions in the sinker pressing cam 130 press the floating yarn in sequence to ensure the pressing effect of the floating yarn. The needle plate 210 of the flat knitting machine is equipped with several rotatable sinker plates 220. Above the needle plate assembly 200 is a knitting head that moves along the length of the needle plate 210. The knitting head is equipped with two or more sets of sinker plate movable triangle assemblies 120, and sinker plate pressing and floating yarn triangles 130 are arranged between adjacent sets of sinker plate movable triangle assemblies 120. Each set of sinker plate movable triangle assemblies 120 includes a first sinker plate movable triangle 124 and a second sinker plate movable triangle 125. The first sinker plate movable triangle 124 and the second sinker plate movable triangle 125 are arranged alternately in front and behind during operation. Different sinker plate movable triangles drive the sinker plate movement when the knitting head moves back and forth. That is, in each set of sinker plate movable triangle assemblies 120, one of the two movable triangles, the first sinker plate movable triangle 124 and the second sinker plate movable triangle 125, is in working state to drive the sinker plate movement to realize the pressing and floating yarn operation. In the first embodiment, one setter is in the normally open state, releasing the yarn and returning it to its original position. The arrangement of two movable triangles in each group results in a greater distance between the movable triangles in the first and second groups that drive the sinker to press the float, leading to a greater distance between the float at the pressing position and the knitting position 230 where the yarn is fed. This results in a smaller angle between the float and the needle plate 210, making it difficult for the needle to catch the yarn, causing problems such as loops and / or missing yarn in the knitted product. In this embodiment, a sinker pressing float triangle 130 is set between adjacent sets of movable sinker triangles. This increases the driving position of the sinker pressing float triangle 130, effectively shortening the length of the float and ensuring that the needle can catch it, thus ensuring the quality and effect of the knitted product.
