Description
Technical Field
[0001] This utility model belongs to the technical field of double-cylinder sock machines, and specifically relates to a needle transfer structure on a double-cylinder sock machine. Background Technology
[0002] Double-cylinder sock knitting machines are used to knit more complex socks. They are equipped with an upper cylinder and a lower cylinder, and through the cooperation of needle guide plates, double-ended needles, etc., they can knit socks with raised and recessed patterns.
[0003] In existing technologies, the upper syringe typically uses a transfer rhombus structure to control the up-and-down movement of the guide needle plate, which in turn controls the transfer of the double-headed needle between the upper and lower syringe barrels. However, most current transfer rhombus structures lack relevant limiting structures. That is, after the guide needle plate finishes its upward movement, it may unnecessarily jump upward due to inertia. This unstable fluctuation limits the machine's operating speed and is not conducive to improving production efficiency. Utility Model Content
[0004] The purpose of this invention is to address the aforementioned problems in the existing technology by proposing a needle transfer structure for a double-needle sock machine.
[0005] To achieve the innovative objectives of this utility model, the following technical solutions can be used: A needle transfer structure for a double-needle sock machine includes a mounting plate. The mounting plate has a transfer rhombus on its arc-shaped inner side. The transfer rhombus includes a guide slope that can cooperate with the needle feet of the needle guide plate and guide them upward. The bottom of the guide slope is connected to the horizontal needle track surface, and a limiting rhombus is provided above the top of the slope.
[0006] This utility model's transfer rhombus structure is suitable for use in double-cylinder sock knitting machines. Its mounting plate extends vertically along a straight line and circumferentially along an arc, forming a circular arc plate. This mounting plate, along with other similar structural components, forms a cylindrical upper needle cylinder. The needle guide slides along the inner needle track via the needle feet. A guide slope is provided on the upstream side of the transfer rhombus, connecting to the needle track and guiding the needle guide upwards. This allows the double-ended needles connected to the needle guide to transfer between the lower and upper needle cylinders, creating a textured pattern on the sock surface. Furthermore, a limiting rhombus is provided above the transfer rhombus to apply a downward limit after the needle guide is guided upwards, preventing excessive upward jumping due to inertia and ensuring smooth movement of the needle guide, thus improving production efficiency. Specific details regarding the interaction between the double-ended needles and the needle guide are existing technology and will not be elaborated further.
[0007] In the above-mentioned needle transfer structure of the double-needle sock machine, the guide slope includes an inclined plane and a connecting arc surface. One end of the connecting arc surface is smoothly connected to the lower end of the inclined plane, and the other end is smoothly connected to the needle track surface.
[0008] The guide slope mainly guides the pins that slide in contact with it upwards through the inclined plane. The inclined plane slopes upwards towards the upstream direction, while the connecting arc surface is used to achieve a smooth transition from the needle track surface to the inclined plane, ensuring that the pins slide smoothly onto the inclined plane.
[0009] In the needle transfer structure of the aforementioned double-needle sock machine, the angle between the inclined plane and the needle track surface is between 150 and 160 degrees.
[0010] The angle of the inclined plane is related to the stability of the upward guidance of the guide pin. An excessively large angle requires a longer circumferential length, increasing the space required for installation. An excessively small angle can easily cause large fluctuations during upward guidance, increasing the possibility of pin breakage and limiting the maximum operating speed. The angle in this design is between 150-160 degrees, providing smooth upward sliding guidance of the guide pin with minimal fluctuations, which helps improve operating speed and production efficiency. 155 degrees is the preferred angle. Note: The angle described here is based on the assumption that the mounting plate is flattened into a plate shape; the radius of the connecting arc surface is similarly considered.
[0011] In the aforementioned needle transfer structure of the double-needle sock machine, the radius of the connecting arc surface is between 10-14 mm.
[0012] The function of the connecting arc surface is equivalent to adjusting the movement direction of the stitch from horizontal to oblique upward. The radius of this arc surface is directly related to the speed of this change. Too large or too small a radius may affect stability. The radius of the connecting arc surface in this solution is between 10-14mm to ensure a smooth transition. 12mm is the preferred radius.
[0013] In the above-mentioned needle transfer structure of the double needle cylinder sock machine, the upper end of the inclined plane is connected to the transfer top surface of the transfer rhombus, the transfer top surface and the inclined plane are rounded, and the limiting rhombus is located above the transfer top surface.
[0014] The rounded corners between the inclined plane and the transfer top surface allow the pin to slide smoothly out of the guide slope. The limiting rhombus is located in the extension direction of the inclined plane, which is equivalent to the inertial direction of the pin, ensuring effective cooperation with the pin and guiding the pin towards the transfer top surface to avoid jumping.
[0015] In the above-mentioned needle transfer structure of the double needle cylinder sock machine, the limiting rhombus is detachably fixed to the arc-shaped inner side of the mounting plate, and the limiting rhombus has a limiting inclined surface facing the top of the guide slope at least at the upstream end.
[0016] The limiting angle can be fixed by a structure such as bolts to ensure flexible disassembly. The limiting bevel is used to make specific contact with the upper end of the pin to achieve downward and upward guiding and limiting of the top surface.
[0017] In the above-mentioned needle transfer structure of the double-needle sock machine, the apex of the slope is located below the limiting slope, and the limiting slope extends radially and is a straight or curved surface.
[0018] The limiting bevel is used to guide the pin towards the needle passage between the limiting rhombus and the transfer rhombus. The limiting bevel can be a straight or curved surface. In other words, the limiting bevel and the limiting bottom surface of the limiting rhombus together achieve downward limiting of the pin to prevent it from jumping. The extension direction of the limiting bevel is consistent with the extension direction of the pin tip, increasing the contact area between the two and reducing the wear rate.
[0019] In the needle transfer structure of the double-cylinder sock machine described above, a needle passage is formed between the limiting bottom surface of the limiting rhombus and the transferring top surface of the transfer rhombus for the needle to pass through, and the limiting bottom surface and the limiting inclined surface are smoothly connected by rounded corners.
[0020] The height of the needle passage is adapted to the height of the needle, ensuring that the needle passes through smoothly and stably. The bottom surface of the limiting plate and the inclined surface of the limiting plate are provided with rounded corners, which realizes a smooth transition from the contact between the top of the needle and the contact between the inclined surface of the limiting plate and the contact between the bottom surface of the limiting plate.
[0021] In the above-mentioned needle transfer structure of the double needle cylinder sock machine, the downstream end of the limiting rhombus is provided with a relief slope that is smoothly connected to the bottom surface of the limiting, and the relief slope slopes downwards and downstream. The upstream and downstream ends of the limiting rhombus are acute triangles, and the middle part is rectangular. The yielding slope and the limiting slope are located on the lower side of the triangle.
[0022] The yielding ramp provides clearance for the upward guidance of the pin in the downstream direction. The vertical cross-sections at both ends of the limiting rhombus are acute triangles, with the vertical sides of the triangles connected to the middle section. The downward-sloping sides form the yielding ramp or limiting ramp. The acute triangle has greater structural strength. Furthermore, the downstream end of the limiting rhombus extends to the side of the mounting plate, and a notch is provided on the radially outer side of this downstream end to prevent interference with the downstream splicing mechanism.
[0023] In the aforementioned needle transfer structure of the double-needle sock machine, the guide slope, the limiting rhombus, and the transfer rhombus all extend radially relative to the center of the mounting plate.
[0024] The extension directions of the guide slope, limiting rhombus, and transfer rhombus are adapted to the extension direction of the pin, ensuring the contact area between the corresponding mating surface and the pin, and reducing the wear rate.
[0025] Compared with the prior art, the present invention has the following main advantages: 1. A guide slope is provided on the upstream side of the transfer rhombus. This guide slope is connected to the needle track and can guide the guide needle plate upward, so that the double-headed needle connected to the guide needle plate can be transferred between the lower needle cylinder and the upper needle cylinder, thereby achieving the effect of knitting concave and convex textures on the surface of the sock. In addition, a limiting rhombus is provided above the transfer rhombus to apply a downward limit after the guide needle plate is guided upward, so as to prevent the guide needle plate from jumping too much upward due to inertia, ensuring the smooth movement of the guide needle plate and helping to improve production efficiency.
[0026] 2. The included angle of the inclined plane is between 150 and 160 degrees, which provides smooth upward sliding guidance for the guide pin with little fluctuation, thus helping to improve operating speed and production efficiency.
[0027] 3. The radius of the connecting arc surface is between 10-14mm to ensure a smooth transition, with 12mm being the preferred radius.
[0028] 4. The rounded corners between the inclined plane and the transfer top surface allow the pin to slide smoothly out of the guide slope. The limiting rhombus is located in the extension direction of the inclined plane, which is equivalent to being located in the inertial direction of the pin, ensuring effective cooperation with the pin and guiding the pin towards the transfer top surface to avoid jumping.
[0029] 5. The vertical cross-sections at both ends of the limiting rhombus are acute triangles. The vertical side of the triangle is connected to the middle part, and the downward-sloping side forms a yielding slope or limiting slope. The acute triangle has greater structural strength.
[0030] 6. The extension directions of the guide slope, limiting rhombus, and transfer rhombus are adapted to the extension direction of the pin, ensuring the contact area between the corresponding mating surface and the pin, and reducing the wear rate. Attached Figure Description

[0032] In the diagram, 1 is the mounting plate, 2 is the upper syringe, 3 is the transfer rhombus, 4 is the guide slope, 5 is the needle track surface, 6 is the limiting rhombus, 7 is the inclined plane, 8 is the connecting arc surface, 9 is the transfer top surface, 10 is the limiting slope, 11 is the limiting bottom surface, 12 is the needle passage, 13 is the yielding slope, and 14 is the notch. Detailed Implementation
[0033] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.
[0034] Specific implementation examples Figure 1-3 As shown, the needle transfer structure of this double needle cylinder sock machine includes a mounting plate 1. The inner arc-shaped side of the mounting plate 1 is provided with a transfer rhombus 3. The transfer rhombus 3 includes a guide slope 4 that can cooperate with the needle foot of the guide needle plate to guide upward. The bottom of the guide slope 4 is connected to the horizontal needle track surface 5, and a limiting rhombus 6 is provided above the top of the slope.
[0035] Specifically, the mounting plate 1 is an arc-shaped plate, and a guide slope 4 is provided on the upstream side of the transfer rhombus 3. The guide slope 4 is connected to the needle track surface 5, which can guide the guide needle plate upward, so that the double-headed needle connected to the guide needle plate can be transferred between the lower needle cylinder and the upper needle cylinder, thereby achieving the effect of knitting concave and convex textures on the surface of the sock. In addition, a limiting rhombus 6 is provided above the transfer rhombus 3, which is used to apply a downward limit after the guide needle plate is guided upward, so as to prevent the guide needle plate from jumping too much upward due to inertia, ensuring the smooth movement of the guide needle plate and helping to improve production efficiency.
[0036] like Figure 1 , 2 As shown, the guide slope 4 includes an inclined plane 7 and a connecting arc surface 8. One end of the connecting arc surface 8 is smoothly connected to the lower end of the inclined plane 7, and the other end is smoothly connected to the needle track surface 5. The angle between the inclined plane 7 and the needle track surface 5 is 155 degrees, and the radius of the connecting arc surface 8 is 12mm. The upper end of the inclined plane 7 is connected to the transfer top surface 9 of the transfer rhombus 3. The transfer top surface 9 and the inclined plane 7 have rounded corners, and the limiting rhombus 6 is located above the transfer top surface 9.
[0037] Specifically, the guide slope 4 primarily guides the needle upwards via the inclined plane 7, while the connecting arc surface 8 facilitates a smooth transition between the needle track surface 5 and the inclined plane 7, ensuring the needle slides smoothly onto the inclined plane 7. The angle between the inclined plane 7 and the needle track surface 5 is 155 degrees, and the radius of the connecting arc surface 8 is 12mm, resulting in smooth upward sliding of the guide needle with minimal fluctuations, thus improving operating speed and production efficiency. The rounded corner between the inclined plane 7 and the transfer top surface 9 allows the needle to slide smoothly off the guide slope 4. The limiting rhombus 6 is located in the extension direction of the inclined plane 7, which is equivalent to being located in the inertial direction of the needle, ensuring effective engagement with the needle and guiding it towards the transfer top surface 9 to prevent jumping.
[0038] like Figure 2 , 3 As shown, the limiting rhombus 6 is detachably fixed to the arc-shaped inner surface of the mounting plate 1. The limiting rhombus 6 has a limiting inclined surface 10 at its upstream end facing the top of the guide slope 4, and a yielding inclined surface 13 at its downstream end that smoothly connects to the limiting bottom surface 11. The yielding inclined surface 13 slopes downwards towards the downstream direction. The upstream and downstream ends of the limiting rhombus 6 form an acute triangle, with a rectangular middle section. The yielding inclined surface 13 and the limiting inclined surface 10 are located on the lower side of the triangle. The top of the slope is located below the limiting inclined surface 10, which extends radially and is a straight surface. A needle passage 12 for the needle to pass through is formed between the limiting bottom surface 11 of the limiting rhombus 6 and the transferring top surface 9 of the transferring rhombus 3. The limiting bottom surface 11 and the limiting inclined surface 10 are smoothly connected by rounded corners.
[0039] Specifically, the limiting rhombus 6 is fixed by a bolt structure to ensure flexible disassembly. The limiting slope 10 is used to contact the upper end of the pin to guide and limit its downward movement and transfer to the top surface 9. The yielding slope 13 provides yielding for the upward guidance of the pin by the downstream mechanism. The vertical cross-sections at both ends of the limiting rhombus 6 are acute triangles, with the vertical side of the triangle connected to the middle part. The downward sloping side forms the yielding slope 13 or the limiting slope 10. The acute triangle has greater structural strength. The downstream end of the limiting rhombus 6 extends to the side of the mounting plate 1, and a notch 14 is provided on the radially outer side of this downstream end to avoid interference with the downstream splicing mechanism. The limiting inclined surface 10 guides the needle to the needle passage channel 12 between the limiting rhombus 6 and the transfer rhombus 3. Specifically, the limiting inclined surface 10 is a straight surface. In other words, the limiting inclined surface 10 and the limiting bottom surface 11 of the limiting rhombus 6 together achieve anti-runaway limiting of the needle. The extending direction of the limiting inclined surface 10 is consistent with the extending direction of the needle tip, increasing the contact area and reducing the wear rate. The height of the needle passage channel 12 is adapted to the height of the needle, ensuring smooth and stable passage. A rounded corner is provided between the limiting bottom surface 11 and the limiting inclined surface 10, achieving a smooth transition from contact between the needle tip and the limiting inclined surface 10 to contact between the needle tip and the limiting bottom surface 11.
[0040] In this embodiment, the guide slope 4, the limiting rhombus 6, and the transfer rhombus 3 all extend radially relative to the center of the mounting plate 1, that is, the extension direction is adapted to the extension direction of the pin, which ensures the contact area between the corresponding mating surface and the pin and reduces the wear rate.
[0041] Specific working principle: The guide needle plate moves circumferentially inside the upper syringe 2. When upward guidance is required, the needle foot slides from the needle track surface 5 through the connecting arc surface 8 onto the inclined plane 7. The guide needle plate begins to move upward, controlling the double-headed needle to move upward into the syringe 2. At the end of the upward stroke, the needle foot leaves the guide slope 4 through a rounded corner. The top of the needle foot contacts the limiting plane 10 and is guided downward. It slides steadily on the transfer top surface 9 and continues to move to the relevant mechanism behind after sliding out of the needle passage 12.

Those skilled in the art to which this utility model pertains may make various modifications or additions to the described specific embodiments or use similar methods to substitute them, without departing from the spirit of this utility model or exceeding the scope defined by the appended claims.
