Technical Field
[0001] This utility model relates to the field of sock machine technology, and more specifically, to a diamond-shaped press needle structure. Background Technology
[0002] Socks are an essential item in people's lives, serving not only to prevent chafing and slipping, but also to keep warm and absorb sweat. They are mainly composed of the toe, sole, heel, leg, and cuff. Different parts of the sock require different needle positions when knitting. Currently, the presser plate and cast-on knife in presser stitches need to be controlled separately, making it impossible to form an effective combination. Utility Model Content
[0003] The purpose of this utility model is to overcome the shortcomings of the prior art and provide a diamond-shaped pressure pin structure.
[0004] To achieve the above objectives, the present invention adopts the following technical solution:
[0005] This utility model discloses a diamond-shaped pressure needle structure, including a mounting base, a needle-starting knife assembly driven and connected inside the mounting base, a mounting plate mounted on the upper part of the mounting base, a diamond-shaped pressure needle mounted on the mounting plate, a pressure plate assembly hinged to the diamond-shaped pressure needle, a spring installed between the pressure plate assembly and the diamond-shaped pressure needle, and the needle-starting knife assembly abutting against the lower end of the pressure plate assembly.
[0006] Furthermore, the pressure plate assembly includes a vertically arranged transmission block, a pressure plate connected to the upper part of the transmission block, the pressure plate being horizontally arranged, a second mounting hole being provided at the connection between the transmission block and the pressure plate, a first mounting hole being provided on the central rhombus, and a mounting shaft passing through the first and second mounting holes.
[0007] Furthermore, a positioning hole is provided at the upper part of the middle rhombus, and the lower end of the spring is set in the positioning hole.
[0008] Furthermore, the mounting base has a stepped hole, and the needle-starting knife assembly includes a guide rod that passes through the stepped hole. The end of the guide rod outside the stepped hole is connected to a mounting block. The needle-starting knife is mounted on the side of the mounting block away from the guide rod. A pressure block is connected to the upper part of the mounting block, and the pressure block abuts against the left side of the lower end of the transmission block.
[0009] Furthermore, a support block is installed on the mounting base at the left side of the stepped hole.
[0010] Furthermore, the stepped hole includes a large-diameter section and a small-diameter section that are connected. A cylinder core is installed in the large-diameter section. The end of the guide rod away from the mounting block extends from the small-diameter section into the large-diameter section and is connected to the cylinder core. A second spring is installed in the large-diameter section. One end of the second spring abuts against the stepped seat at the connection between the small-diameter section and the large-diameter section, and the other end abuts against the cylinder core. A fixed seat is installed at the right end of the mounting seat at the position of the stepped hole. A through hole is opened on the fixed seat and is connected to the stepped hole.
[0011] Furthermore, a sealing ring is installed on the mounting base at the right end of the stepped hole.
[0012] Furthermore, a sealing groove is provided on the side of the fixing base facing the mounting base, and a sealing ring is provided in the sealing groove.
[0013] The beneficial effects of this utility model are: by installing a needle-starting knife assembly below the central diamond angle, it serves as a needle-following tool for sewing. At the same time, the movement of the needle-starting knife assembly controls the movement of the pressure plate assembly. When sewing the heel of the sock, the needle-starting knife assembly moves backward to control the pressure plate assembly to press down, and the pressure plate assembly presses down the needle to ensure the flatness of the heel of the sock. When sewing the toe, the needle-starting knife assembly moves forward to control the pressure plate assembly to rise, and the pressure plate assembly lifts up to satisfy the action when sewing the toe.

Detailed Implementation
[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0018] like Figures 1-2As shown, a type of diamond-shaped pressure needle structure includes a mounting base 1. A pressure needle knife 6 is mounted on the left end of the mounting base 1. A needle-lifting knife assembly 2 is driven and connected inside the mounting base 1. The needle-lifting knife assembly 2 includes a guide rod 9. The end of the guide rod 9 is connected to a mounting block 10. A needle-lifting knife 12 is connected to the left side of the mounting block 10. A pressure block 11 is connected to the upper part of the mounting block 10. A stepped hole 7 is opened in the mounting base 1. The stepped hole 7 includes a large-diameter section and a small-diameter section that are connected. A cylinder core 21 is provided in the large-diameter section. One end of the guide rod 9, away from the mounting block 10, extends from the small-diameter section into the large-diameter section and is connected to the cylinder core 21. A second spring 20 is provided in the large-diameter section. One end of the second spring 20 abuts against the stepped seat at the connection between the small-diameter section and the large-diameter section, and the other end abuts against the cylinder core 21. A fixed seat 23 is installed at the right end of the mounting base 1 at the position of the stepped hole 7. A through hole 24 is opened on the fixed seat 23 and is connected to the stepped hole 7.
[0019] Mounting plate 3 is mounted on the upper part of mounting base 1. A central rhombus 4 is connected to the left side of mounting plate 3. A pressure plate assembly 5 is rotatably connected to the central rhombus 4. A spring 14 is installed between the central rhombus 4 and the pressure plate assembly 5. The pressure plate assembly 5 includes a vertically arranged transmission block 16. A pressure plate 19 is connected to the upper part of the transmission block 16 and is horizontally arranged. The lower end of the transmission block 16 extends close to the mounting block 10. The right end face of the pressure block 11 abuts against the left side of the lower end of the transmission block 16.
[0020] During sewing, gas is pumped into the stepped hole 7 through the through hole 24, pushing the cylinder core 21 to move to the left within the stepped hole 7. The cylinder core 21 then drives the guide rod 9 to move to the left, while simultaneously compressing the second spring 20. The guide rod 9 drives the pressure block 11 on the mounting block 10 to move to the left. Under the action of the first spring 14, the pressure plate 19 and the transmission block 16 rotate clockwise, and the pressure plate 19 rises to meet the needle position requirements of the sewing head. At the same time, the needle-starting knife 12 on the mounting block 10 is pushed out to the left to serve as a needle picker at the sewing head. Gas is no longer pumped into the stepped hole 7 through the through hole 24. Under the action of the compressed second spring 20 returning to its original position, the cylinder core 21 drives the guide rod 9 to move to the right, thereby driving the pressure block 11 on the mounting block 10 to move to the right. The pressure block 11 compresses the transmission block 16, causing the pressure plate 19 to rotate counterclockwise and descend. The pressure plate 19 presses the needle down to meet the needle position requirements during processing at the heel of the sock, ensuring the flatness of the heel.
[0021] A sealing ring 22 is installed on the mounting base 1 at the right end of the stepped hole 7. The sealing ring 22 seals the end of the stepped hole 7 to prevent leakage of pumped gas.
[0022] The mounting base 23 covers the stepped hole 7, and a sealing groove 25 is provided on the side of the mounting base 1 facing the mounting base 1. A sealing ring 26 is provided in the sealing groove 25. The sealing ring 26 and the sealing groove 25 cooperate to achieve a seal between the mounting base 23 and the mounting base 1, preventing gas in the stepped hole 7 from leaking out from the gap between the mounting base 23 and the mounting base 1.
[0023] A second mounting hole 17 is provided at the connection between the transmission block 16 and the pressure plate 19, and a first mounting hole 15 is provided on the middle rhombus 4. A mounting shaft 18 is inserted into the first mounting hole 15 and the second mounting hole 17, thereby realizing the rotational connection between the middle rhombus 4 and the pressure plate assembly 5.
[0024] The middle rhombus 4 has a positioning hole 13 on its upper part, and the lower end of the spring 14 is set in the positioning hole 13. The middle rhombus 4 is positioned by the positioning hole 13.
[0025] A support block 8 is installed on the mounting base 1 at the left end of the stepped hole 7. The support block 8 supports the mounting block 10 and prevents the mounting block 10 from deflecting.
[0026] The above description is merely a preferred embodiment of this utility model. The protection scope of this utility model is not limited to the above embodiments. All technical solutions falling within the scope of this utility model's concept are protected. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of this utility model should also be considered within the protection scope of this utility model.
