Description

Technical Field

[0001] This utility model relates to the field of circular knitting machine technology, specifically to a needle cylinder triangular assembly for a circular knitting machine and a circular knitting machine. Background Technology

[0002] Circular knitting machines, also known as circular weft knitting machines, have developed rapidly and gained widespread use due to their numerous loop-forming systems, high speed, high output, rapid pattern changes, good fabric quality, fewer processes, and strong product adaptability.

[0003] An insert is provided on the circumferential side wall of the needle cylinder of a circular knitting machine, forming a carrier for the knitting needles. A cam assembly is located on the outer circumference of the needle cylinder, with a cam plate on its cam seat. The knitting needle is installed in the needle groove of the insert and fixed to the circumferential side wall of the needle cylinder by a spring and a pressure plate. The heel of the knitting needle is inserted into the needle guide groove of the cam plate. During operation, the needle cylinder drives the knitting needle to rotate, causing the needle to move up and down along the needle guide groove of the cam plate. The knitting needles on the needle cylinder cooperate with the knitting needles on the needle plate to perform knitting actions.

[0004] The inventors of this application have discovered that the pressure pin blocks are prone to tilting during assembly due to inaccurate fixing, causing friction between the top surface of the pressure pin block and the spring above it, resulting in wear and breakage of the spring after long-term operation; moreover, the gap between adjacent pressure pin blocks is very small, and the tilting of the pressure pin blocks will make it difficult to assemble adjacent pressure pin blocks and triangular seats.

[0041] The technical solution of this utility model will be described in detail below with specific embodiments. The following specific embodiments can be combined with each other, and the same or similar concepts or processes may not be described again in some embodiments.

[0042] As described in the background section of this application, the knitting needle is mounted on a insert and fixed to the needle cylinder by a spring and a pressure block. The needle heel is inserted into the needle groove of the triangular plate. During operation, the needle cylinder drives the knitting needle to rotate and moves the needle up and down along the needle groove of the triangular plate. The knitting needle on the needle cylinder cooperates with the knitting needle on the needle plate to perform knitting action.

[0043] The inventors of this application have discovered that the pressure pin blocks are prone to tilting during assembly due to inaccurate fixing, causing friction between the top surface of the pressure pin block and the spring above it, resulting in wear and breakage of the spring after long-term operation; moreover, the gap between adjacent pressure pin blocks is very small, and the tilting of the pressure pin blocks will make it difficult to assemble adjacent pressure pin blocks and triangular seats.

[0044] To address the aforementioned problems, the inventors of this application have proposed a technical solution, the specific embodiments of which are as follows:

[0045] Example 1

[0046] Figure 1 This is a schematic diagram of the triangular syringe assembly for a large circular knitting machine in Embodiment 1 of this utility model. Figure 2 This is an exploded view of the syringe triangular assembly in Embodiment 1 of this utility model. Figure 3 This is a partial cross-sectional view of the syringe triangular assembly in Embodiment 1 of this utility model. Figure 4 This is a schematic diagram of the guide block in Embodiment 1 of this utility model. Figure 5 This is a schematic diagram of the axial screw in Embodiment 1 of this utility model.

[0047] like Figures 1 to 5 As shown, the triangular assembly of the syringe for the large circular knitting machine in this embodiment includes: a triangular base 1, a triangular piece 2, a guide block 3, and a shaft screw 4.

[0048] The triangular base 1 is fixedly mounted on the triangular seat ring of the large circular knitting machine.

[0049] Triangular piece 2 is set on the side wall of triangular base 1.

[0050] The axial screw 4 includes: a nut 41, a first smooth circular section 42, and a first threaded section 43.

[0051] The first smooth circular segment 42 is located between the nut 41 and the first threaded segment 43, and the outer diameter of the first smooth circular segment 42 is slightly larger than the outer diameter of the first threaded segment 43.

[0052] The guide block 3 is provided with a fixed through hole 301 and an arc-shaped side wall 302.

[0053] The fixing through hole 301 of the guide block 3 is adapted to the first smooth circular segment 42 of the shaft screw 4, and the arc of the arc side wall 302 of the guide block 3 is adapted to correspond to the arc of the circular side wall of the syringe.

[0054] The top of the triangular base 1 is provided with a threaded hole 11, which includes a second smooth circular section and a second threaded section.

[0055] The second threaded section of the threaded hole 11 of the triangular base 1 is adapted to the first threaded section 43 of the shaft screw 4. The diameter of the second smooth circular section of the threaded hole 11 is adapted to the outer diameter of the first smooth circular section 42, and the length of the second smooth circular section is less than the length of the first smooth circular section 42.

[0056] The triangular base 1 has two threaded holes 11, which are arranged horizontally side by side. Correspondingly, the guide block 3 also has two fixing through holes 301, and the positions of the two fixing through holes 301 correspond to the positions of the two threaded holes 11.

[0057] Two axial screws 4 are inserted into the two fixing through holes 301 of the guide block 3 and into the threaded hole 11 of the triangular base 1. The first threaded section 43 of the axial screw 4 engages with the second threaded section of the triangular base 1. When the axial screw 4 is tightened, the nut 41 of the axial screw 4 abuts against the guide block 3, fixing the guide block 3 to the triangular base 1. The first smooth circular section 42 of the axial screw 4 passes through the second smooth circular section of the threaded hole 11 of the triangular base 1 and the fixing through hole 301 of the guide block 3, so that the guide block 3 is accurately positioned and firmly fixed on the triangular base 1, and will not loosen. It also keeps the top surface of the guide block 3 horizontal and will not contact the spring above it, thus preventing wear on the spring.

[0058] The arc-shaped sidewall 302 of the guide block 3 abuts against the knitting needle on the needle cylinder, pressing the knitting needle against the circumferential sidewall of the needle cylinder, so that the knitting needle can only move up and down along the axial direction and does not wobble radially.

[0059] It is not difficult to see from the above that the triangular syringe assembly for the large circular knitting machine in this embodiment is provided with a triangular base, a triangular piece, a guide block, and a shaft screw. The triangular piece is set on the triangular base. The shaft screw includes a nut, a first smooth circular segment, and a first threaded segment. The outer diameter of the first smooth circular segment is larger than the outer diameter of the first threaded segment. The guide block is provided with a fixed through hole and an arc-shaped sidewall. The triangular base is provided with a threaded hole, which includes a second smooth circular segment and a second threaded segment. The shaft screw passes through the fixed through hole and extends into the threaded hole of the triangular base, so that the guide block is fixed on the triangular base. In this embodiment, the triangular assembly for a large circular knitting machine has multiple triangular bases arranged in a circular pattern on the outer circumference of the syringe. The guide pressure block is fixed to the threaded hole of the triangular base by two axial screws, so that the guide pressure block is precisely positioned on the triangular base and firmly fixed. The top surface of the guide pressure block remains horizontal and does not tilt, and the multiple guide pressure blocks on the outer side of the syringe are located on the same horizontal plane. The guide pressure block will not come into contact with the spring above it and rub against it, thus preventing wear of the spring. Moreover, the guide pressure block is accurately positioned and remains horizontal, which facilitates the assembly of the triangular base and the guide pressure block.

[0060] Optionally, in this embodiment, the triangular syringe assembly for the large circular knitting machine has a right-angled L-shaped guide block 3, which includes a vertical plate 31 and a horizontal plate 32.

[0061] The fixed through hole 301 is set on the vertical plate 31, so that the vertical plate 31 is fixed to the threaded hole 11 of the triangular base 1 by the shaft screw 4. The outer side wall of the horizontal plate 32 is arc-shaped, which is the arc-shaped side wall 302 of the guide pressure block 3. The outer side wall of the horizontal plate 32 is used to hold the knitting needle and press the knitting needle against the circumferential side wall of the needle cylinder.

[0062] Optionally, the triangular assembly for the syringe of the large circular knitting machine in this embodiment also includes: a slider 5.

[0063] The triangular base 1 has a vertical groove 12 along its axial direction. The slider 5 is slidably disposed within the groove 12 of the triangular base 1 and is fixed by a connector. The triangular piece 2 is fixed to the slider 5 by screws, which facilitates the fixing and position adjustment of the triangular piece 2.

[0064] Furthermore, the triangular assembly for the syringe of the large circular knitting machine in this embodiment also includes: a limiting block 6.

[0065] The limiting block 6 is set on the triangular base 1, located below the slider 5. When the limiting block 6 abuts against the slider 5, it prevents the slider 5 from sliding and prevents the slider 5 from sliding down the triangular base 1.

[0066] Optionally, in this embodiment, the fixing through hole 301 of the guide block 3 of the large circular knitting machine needle tube triangular assembly is a stepped hole.

[0067] The larger end of the step of the fixed through hole 301 (stepped hole) is used for the nut 41 of the shaft screw 4 to be inserted.

[0068] Optionally, in this embodiment, the nut 41 of the shaft screw 4 of the large circular knitting machine triangular assembly is provided with a cross groove 411 for inserting a cross wrench to facilitate the rotation of the shaft screw 4.

Figure 6 Enlarged view of point A in the image. Figure 8 This is a partial schematic diagram of the circular knitting machine in Embodiment 2 of this utility model.

[0071] like Figures 6 to 8 As shown, the circular knitting machine of this embodiment includes: a circular knitting machine body and a cylinder triangular assembly as described in the above embodiment.

[0072] The knitting needles 120 of the large circular knitting machine body are mounted on the needle cylinder 110. The knitting needles 120 are surrounded by springs 130, so that the knitting needles 120 are attached to the circumferential side wall of the needle cylinder 110.

[0073] Multiple triangular bases 1 are arranged in a circular pattern on the outer circumference of the needle cylinder 110. Guide blocks 3 are mounted on the triangular bases 1 via shaft screws 4. The arcuate sidewall 302 of the guide blocks 3 abuts against the knitting needle 120, pressing the knitting needle 120 against the circumferential sidewall of the needle cylinder 110, preventing radial runout of the knitting needle 120 during up-and-down movement. At the same time, the guide blocks 3 are precisely positioned and firmly assembled on the triangular bases 1, with their top surfaces remaining horizontal. Furthermore, the top surfaces of multiple guide blocks 3 are located on the same horizontal plane, preventing the guide blocks 3 from contacting and rubbing against the spring 130 above them, thus avoiding wear on the spring 130. The precise positioning and horizontal alignment of the guide blocks 3 facilitates the assembly of multiple triangular bases and guide blocks on the outer side of the needle cylinder.

[0075] Furthermore, "above," "on top of," and "above" the first feature in relation to the second feature can mean that the first feature is directly above or diagonally above the second feature, or simply that the first feature is at a higher horizontal level than the second feature. Similarly, "below," "under," and "beneath" the first feature in relation to the second feature can mean that the first feature is directly below or diagonally below the second feature, or simply that the first feature is at a lower horizontal level than the second feature.
