Description

Technical Field

[0001] This invention discloses a knitting machine and knitting process with adjustable knitting density for knitted fabrics, belonging to the field of knitted fabric textile technology. Background Technology

[0002] Knitted fabric is a type of fabric formed by bending yarn into loops and interlocking them using knitting needles. The difference between knitted and woven fabrics lies in the form of the yarn within the fabric. Knitting is divided into weft knitting and warp knitting, and knitted fabrics are widely used in clothing fabrics and linings, home textiles, and other products. In weft knitting, knitting is typically done using needles on a circular knitting machine to form loops. However, because the diameter of the cylinder is standard, the number of needles installed and the number of needles produced are essentially fixed. Therefore, the difference in the fabric's structure lies in the pattern, which cannot be adjusted according to the stitch count. In other words, currently, with a single cylinder, it is impossible to knit both high-stitch-count and low-stitch-count fabrics by changing the number of needles produced. Therefore, there is an urgent need to develop a new type of knitting machine to meet production needs. Summary of the Invention

[0003] The purpose of this invention is to solve the problems in the prior art by providing a knitting machine and knitting process with adjustable knitting density for knitted fabrics.

[0004] The present invention achieves the above-mentioned objective through the following technical solution: a knitting machine with adjustable knitting density for knitted fabric, comprising a cylinder, a first knitting needle, a first knitting triangle, a triangle holder, and a fixed base. The triangle holder is fixed on the fixed base. The first knitting triangle includes a cast-on block, a return block, and a plain knitting block. Multiple sets of the cast-on block, return block, and plain knitting block are arranged in sequence and distributed around the outer periphery of the cylinder. Each cast-on block, return block, and plain knitting block is provided with a cast-on groove, a return groove, and a plain knitting groove, respectively. The cylinder is provided with a mounting groove, and an adjusting component for controlling the sliding state of the first knitting needle is provided in the mounting groove. The adjusting component includes a sliding plate and a guide plate. The sliding plate and the guide plate are both slidably disposed in the mounting groove, and the two ends of the sliding plate are respectively connected to the first needle and the guide plate with a first insert rod and a second insert rod. The first needle has a first groove for the first insert rod to slide at the end near the sliding plate. The first groove has an L-shaped structure and includes a first horizontal groove and a first vertical groove. The guide plate has a second groove for the second insert rod to slide at the end near the sliding plate. The second groove is a horizontal groove. The sliding plate is also provided with a needle heel that slides along the starting groove, the return groove and the flat needle groove. The outer side of the flat needle block is provided with a power component for driving the sliding plate to slide along the first horizontal groove and the second groove.

[0005] Preferably, both ends of the sliding plate are provided with protrusions, which face the triangular seat and have notches. The needle heel is located between the two protrusions. The power assembly includes a power component and a drive rod mounted on the power component. The power component is a cylinder or an electric telescopic rod. One end of the drive rod has the same shape as the protrusions and is fixedly connected to the power component. The drive rod is slidably disposed with respect to the triangular seat.

[0006] Preferably, one end of the sliding piece is provided with a guide groove for the first knitting needle to slide vertically, and the other end has a positioning groove that cooperates with the sliding piece.

[0007] Preferably, the mounting groove is provided with two positioning plates corresponding to the position of the first knitting needle. The positioning plates are provided with grooves. The first knitting needle is vertically slidably disposed between the two positioning plates. The outer periphery of the needle cylinder is fixed with a first positioning ring and a second positioning ring. The first positioning ring cooperates with the groove. The second positioning ring is located outside the guide plate. The first positioning ring and the second positioning ring are respectively used to prevent the first knitting needle and the guide plate from sliding towards the triangular seat along with the sliding plate.

[0008] Preferably, it further includes a sinker plate, a sinker plate, and a second knitting triangle. The sinker plate is located on the upper outer side of the needle cylinder. The sinker plate is horizontally slidably disposed on the sinker plate. The second knitting triangle is located above the sinker plate and is used to drive the sinker plate to slide. The sinker plate is arranged at intervals with the first knitting needle.

[0009] Preferably, it further includes a needle plate, a second knitting needle, and a third knitting triangle. The needle plate is located above the needle cylinder. The second knitting needle is horizontally slidably disposed on the needle plate. The third knitting triangle is located above the second knitting needle and is used to drive the second knitting needle to slide. The second knitting needle and the first knitting needle are arranged alternately.

[0010] A knitting process for adjustable knitting density of knitted fabric includes the following steps:

[0011] S1: Install the first needle, guide plate, sliding plate and positioning plate in the mounting groove of the needle cylinder, keeping the height of the needle heel on the sliding plate protruding from the outside of the needle cylinder to the minimum.

[0012] S2: Arrange multiple cast-on blocks, backstitch blocks and plain stitch blocks in groups of three, and record the group of cast-on blocks, backstitch blocks and plain stitch blocks as a knitting path. Then fix it on the triangle base, and at the same time make the needle heels on the sliding plate aligned with the cast-on groove, backstitch groove and plain stitch groove, and the needle heels have room to move in the direction closer to the triangle base.

[0013] S3: Install the power unit at the position of the flat pin block corresponding to the triangular seat, and make one end of all the drive rods located in the notch on the corresponding sliding plate;

[0014] S4: The needle cylinder is driven to rotate by the transmission structure inside the knitting machine. When the sliding plate rotates with the needle cylinder, its needle heel slides along the starting groove, return groove and flat groove. When the needle heel slides to the flat groove, the height of the protrusion on the sliding plate is consistent with the end of the drive rod.

[0015] S5: Set the motion state of the power component corresponding to the flat needle block. In the first state, all drive rods remain stationary, and the needle heel on the sliding plate slides along the start-up groove and return groove to drive the first needle to complete the needle-out knitting action. In the second state, the power component in the first knitting path drives the drive rod and the sliding plate to slide towards the cam seat, so that when the sliding plate slides along the start-up groove, return groove and flat needle groove, the first needle in this knitting path remains in the non-needle-out state. If the first needle needs to remain non-needle-out in the subsequent second knitting path or other knitting paths, the power component in other knitting paths needs to drive the drive rod to move the same distance towards the cam seat to avoid the rotation of the protrusion on the sliding plate. If the first needle needs to re-emerge and knit in the subsequent second knitting path or other knitting paths, the power component in this knitting path needs to drive the drive rod and the sliding plate to move away from the cam seat.

[0016] Compared with the prior art, the beneficial effects of the present invention are:

[0017] By changing the installation structure of the first needle, the sliding plate can slide within the first groove driven by the power component. When the first insert rod and the first vertical groove are misaligned, the needle heel on the sliding plate can drive the first needle out to complete the knitting action as it slides along the starting and returning grooves. When the first insert rod and the first vertical groove are aligned, the first needle remains stationary as the needle heel slides along the starting and returning grooves. This allows the number of needles produced from the cylinder to be changed. This knitting machine can selectively knit high-count and low-count fabrics, and the position of the first needle can also be adjusted as needed, making control simple and convenient.

[0025] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0026] Example 1

[0027] like Figures 1-4As shown, a knitting machine with adjustable knitting density for knitted fabric includes a cylinder 2, a first knitting needle 1, a first knitting cam 13, a cam seat 5, and a fixed seat 6. The cam seat 5 is fixed on the fixed seat 6. The first knitting cam 13 includes a starting block 14, a return block 15, and a flat knitting block 19. Multiple sets of the starting block 14, return block 15, and flat knitting block 19 are arranged in sequence and distributed around the outer periphery of the cylinder 2. The starting block 14, return block 15, and flat knitting block 19 are respectively provided with a starting groove 20, a return groove 21, and a flat knitting groove 22. The cylinder 2 is provided with a mounting groove 7. An adjusting component for controlling the sliding state of the first knitting needle 1 is provided in the mounting groove 7. The adjusting component includes a sliding piece 10 and a guide piece 11. Both the sliding piece 10 and the guide piece 11 are... The sliding plate 10 is slidably disposed in the mounting groove 7, and the two ends of the sliding plate 10 are respectively connected to the first needle 1 and the guide plate 11 with the first insert rod 23 and the second insert rod 32. The first needle 1 has a first groove 4 for the first insert rod 23 to slide at one end near the sliding plate 10. The first groove 4 has an L-shaped structure and includes a first horizontal groove 24 and a first vertical groove 25. The guide plate 11 has a second groove 31 for the second insert rod 32 to slide at one end near the sliding plate 10. The second groove 31 is a horizontal groove. The sliding plate 10 is also provided with a needle heel 29 that slides along the starting groove 20, the return groove 21 and the flat needle groove 22. The outer side of the flat needle block 19 is provided with a power component 3 for driving the sliding plate 10 to slide along the first horizontal groove 24 and the second groove 31.

[0028] Both ends of the sliding plate 10 are provided with protrusions 26, which face the triangular seat 5 and have notches 27. The needle heel 29 is located between the two protrusions 26. The power assembly 3 includes a power component 16 and a drive rod 18 mounted on the power component 16. The power component 16 is a cylinder or an electric telescopic rod. One end of the drive rod 18 has the same shape as the protrusions 26 and is fixedly connected to the power component 16. The drive rod 18 is slidably disposed with the triangular seat 5. The notches 27 of the protrusions 26 face the triangular seat 5. When installed, one end of the drive rod 18 engages with the notch 27 on one of the sliding plates 10. When the transmission assembly inside the knitting machine drives the needle cylinder 2 to rotate, the sliding plate 10 and the first needle 1 move with the needle cylinder 2. When rotating synchronously, the protrusion 26 will not interfere with the drive rod 18. When it is necessary to make one or more sliding pieces 10 slide horizontally a certain distance towards the triangular seat 5, and knowing the rotation speed of the syringe 2, when the protrusion 26 on a certain sliding piece 10 rotates to the state aligned with the drive rod 18, the power member 16 drives the drive rod 18 to move towards the triangular seat 5 in a short time. If the next adjacent sliding piece 10 needs to maintain the previous state, the power member 16 needs to continue to drive the drive rod 18 to move the same distance away from the triangular seat 5 after the previous sliding piece 10 slides horizontally, so as to avoid interference between the drive rod 18 and the protrusion 26 on the next sliding piece 10.

[0029] One end of the sliding plate 10 is provided with a guide groove 28 for the vertical sliding of the first knitting needle 1, and the other end has a positioning groove 30 that cooperates with the sliding plate 10. The thickness of the first knitting needle 1 is less than that of the mounting groove 7. Therefore, when there is relative movement between the sliding plate 10 and the first knitting needle 1, it is necessary to ensure that the first knitting needle 1 is centered in the mounting groove 7, and at the same time allow the first insert rod 23 to slide smoothly in the first sliding groove 4.

[0030] Two positioning plates 9 are provided in the mounting slot 7 corresponding to the position of the first knitting needle 1. The positioning plates 9 are provided with grooves 17. The first knitting needle 1 is vertically slidably positioned between the two positioning plates 9. The outer periphery of the needle cylinder 2 is fixed with a first positioning ring 8 and a second positioning ring 12. The first positioning ring 8 cooperates with the groove 17. The second positioning ring 12 is located outside the guide plate 11. The first positioning ring 8 and the second positioning ring 12 are respectively used to prevent the first knitting needle 1 and the guide plate 11 from sliding towards the triangle seat 5 along with the sliding plate 10. The positioning plates 9 can play a positioning and guiding role during the knitting process of the first knitting needle 1. At the same time, they also increase the sliding resistance between the positioning plates 9 and the first knitting needle 1. When the first insert rod 23 slides in the first vertical groove 25, the sliding plate 10 can slide with the starting groove 20 and the return groove 21, while the first knitting needle 1 remains stationary. In this embodiment, the first positioning ring 8 restricts the vertical sliding of the positioning plate 9. The first positioning ring 8 and the second positioning ring 12 can also prevent the first knitting needle 1 and the guide plate 11 from sliding synchronously when the sliding plate 10 slides horizontally.

[0031] like Figure 5 As shown, the knitting machine also includes a sinker plate 35, a sinker plate 33, and a second knitting triangle 34. The sinker plate 35 is located on the upper outer side of the needle cylinder 2. The sinker plate 33 is horizontally slidably disposed on the sinker plate 35. The second knitting triangle 34 is located above the sinker plate 33 and is used to drive the sinker plate 33 to slide. The sinker plate 33 is arranged alternately with the first needle 1. After the first needle 1 exits the needle, it hooks the yarn. The sinker plate 33 slides horizontally in the sinker plate 35 and supports the yarn on both sides of the first needle 1, thereby realizing loop knitting. In this way, the first needle 1 and the sinker plate 33 can work together to knit a single-sided fabric.

[0032] A knitting process for adjustable knitting density of knitted fabric includes the following steps:

[0033] S1: Install the first knitting needle 1, guide plate 11, sliding plate 10 and positioning plate 9 in the mounting groove 7 of the needle cylinder 2, and keep the height of the needle heel 29 on the sliding plate 10 protruding from the outside of the needle cylinder 2 at the minimum.

[0034] S2: Arrange multiple starting blocks 14, back stitch blocks 15 and plain stitch blocks 19 in groups of three, and mark this group of starting blocks 14, back stitch blocks 15 and plain stitch blocks 19 as a knitting path. Then fix it on the triangle base 5, and at the same time, align the needle heels 29 on the sliding plate 10 with the starting groove 20, back stitch groove 21 and plain stitch groove 22, and allow the needle heels 29 to move towards the triangle base 5.

[0035] S3: Install the power assembly 3 at the position of the flat pin block 19 corresponding to the triangular seat 5, and make one end of all the drive rods 18 located in the notch 27 on the corresponding sliding plate 10;

[0036] S4: The transmission structure inside the knitting machine drives the cylinder 2 to rotate. When the sliding plate 10 rotates with the cylinder 2, its needle heel 29 slides along the starting groove 20, the return groove 21 and the flat needle groove 22. When the needle heel 29 slides to the position of the flat needle groove 22, the height of the protrusion 26 on the sliding plate 10 is consistent with the end of the drive rod 18.

[0037] S5: Set the motion state of the power component 3 corresponding to the flat needle block 19. In the first state, all drive rods 18 remain stationary. The needle heel 29 on the sliding plate 10 slides along the start-up groove 20 and return groove 21 to drive the first needle 1 to complete the needle-out knitting action. In the second state, the power component 16 in the first knitting path drives the drive rod 18 and the sliding plate 10 to slide towards the cam seat 5 so that when the sliding plate 10 slides along the start-up groove 20, return groove 21 and flat needle groove 22, the first needle 1 in this knitting path remains in the non-needle-out state. If the first needle 1 needs to remain non-needle-out in the second knitting path or other knitting paths, the power component 16 in other knitting paths needs to drive the drive rod 18 to move the same distance towards the cam seat 5 to avoid the rotation of the protrusion 26 on the sliding plate 10. If the first needle 1 needs to re-emerge and knit in the second knitting path or other knitting paths, the power component 16 in this knitting path needs to drive the drive rod 18 and the sliding plate 10 to move away from the cam seat 5.

[0038] Example 2

[0039] like Figure 6 As shown, the difference between this embodiment and the previous embodiment is that in this embodiment, the sinker plate 35, sinker plate and second knitting triangle 34 in embodiment 1 are replaced with needle plate 38, second knitting needle 36 and third knitting triangle 37. The needle plate 38 is located above the needle cylinder 2. The second knitting needle 36 is horizontally slidably arranged on the needle plate 38. The third knitting triangle 37 is located above the second knitting needle 36 and is used to drive the second knitting needle 36 to slide. The second knitting needle 36 and the first knitting needle 1 are arranged alternately. The first knitting needle 1 and the second knitting needle 36 hook the yarn to form a loop when they come out of the needle, so that double-sided fabric can be knitted.

[0040] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the invention can be implemented in other specific forms without departing from its spirit or essential characteristics.
