Description

Technical Field

[0001] This invention belongs to the field of automatic knitting sock machine technology, specifically an automatic knitting sock machine with single and double tracks operating simultaneously and its usage method. Background Technology

[0002] Automatic sock knitting machines come in single-track and double-track versions. Single-track machines use a needle selector to determine the pattern of the socks. However, some special loop structures require double-track machines, where the thread needs to be fed in at two points within a loop. The latter requires significant modifications and alterations to the single-track machine, and also loses some of the selector's features. This not only reduces the choice of sock patterns but also increases the number of components and costs, causing many problems for sock manufacturers in actual production. Summary of the Invention

[0003] In view of the above situation and to overcome the defects of the prior art, the present invention provides an automatic sock knitting machine with single and double tracks running simultaneously and its method of use, which at least partially solves the above technical problems.

[0004] The technical solution adopted by the present invention is as follows: an automatic knitting sock machine with single and double paths, including a knife hole tile and a switching knife, wherein the knife hole tile is provided with a knife-shaped hole and the switching knife is configured to cooperate with the knife-shaped hole;

[0005] The switching blade is configured to function as a single-path automatic sock knitting machine when it does not pass through the blade-shaped hole; and as a double-path automatic sock knitting machine when the switching blade passes through the blade-shaped hole.

[0006] Furthermore, the switching blade is equipped with a feeding device, which can drive the switching blade to move, thereby enabling the switching blade to have two working states: one without passing through the blade-shaped hole and the other through the blade-shaped hole.

[0007] Furthermore, it also includes an operating table, on which a syringe, a middle plate, and a lower plate are provided;

[0008] The middle plate and the lower plate are respectively arranged circumferentially on the outside of the syringe, and the switching knife and the knife hole tile are respectively arranged above the middle plate.

[0009] Furthermore, the syringe barrel is provided with multiple knitting components through grooves, and the knitting components include knitting needles, jacquard needles, and bottom needles;

[0010] The jacquard needle is positioned between the knitting needle and the bottom needle, and the jacquard needle has a protrusion.

[0011] Furthermore, a grooved tile is provided below the middle plate, and the grooved tile has a groove.

[0012] The groove is configured such that when the protrusion moves downward, it can pass through the groove to ensure the movement of the jacquard needle.

[0013] Furthermore, it also includes a sedative tablet, which is positioned above the syringe;

[0014] The switch plate is configured such that when the switching blade passes through the blade hole, the inclined blade surface of the switching blade and the inclined surface of the blade hole combine to form a long downward movement trajectory of the knitting needle. The knitting needle moves up and down on the outside of the needle cylinder. When the needle cylinder and the blade hole plate make relative circular motion, the knitting needle realizes a curved path movement trajectory composed of the blade hole plate and the switching blade.

[0015] The curved path motion trajectory feeds the yarn in the needle into the motion plane of the sinker, achieving weaving with another yarn inside the needle cylinder.

[0016] Furthermore, it also includes a steel ring and a needle selector, the needle selector being mounted on the steel ring, and the steel ring being mounted on the lower plate.

[0017] Furthermore, the steel ring is provided with multiple grooves, and the number of needle selectors is multiple, with each needle selector being disposed on a groove of the steel ring.

[0018] The present invention also provides a method for using an automatic sock knitting machine with both single and double paths operating simultaneously. When the switching blade does not pass through the blade-shaped hole, it is a single-path automatic sock knitting machine; when the switching blade passes through the blade-shaped hole, it is a double-path automatic sock knitting machine.

[0019] Furthermore, when the switching blade passes through the blade-shaped hole:

[0020] The inclined blade surface of the switching blade and the inclined blade hole form a long downward movement trajectory of the knitting needle. The knitting needle moves up and down on the outside of the needle cylinder. When the needle cylinder and the blade hole tile make relative circular motion, the knitting needle realizes a curved path movement trajectory composed of the blade hole tile and the switching blade.

[0021] The curved path motion trajectory feeds the yarn in the needle into the motion plane of the sinker, achieving weaving with another yarn inside the needle cylinder.

[0022] The beneficial effects achieved by the present invention using the above structure are as follows:

[0023] (1) In this embodiment of the invention, the two tiles on the single-path machine are trimmed and an additional switching blade is added to achieve single-path / dual-path switching, which is low cost;

[0024] (2) The present invention makes a modification above the middle plate, which has a large space, making it easy to install and maintain, and does not occupy the space of the middle and lower plates. While introducing the second needle thread, it does not damage the space where the needle selector is installed, and can easily switch back to the single-path state. It can also be adjusted without affecting the number of single-path needle selectors. Attached Figure Description

[0036] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

They are only for the convenience of describing the embodiments of the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on the present invention.

[0038] In the existing technology, the single-channel machine needs to be modified and changed a lot, and the selector of the single-channel machine is also lost. Not only are there fewer choices of sock patterns, but the structure also increases many components and costs, which brings many problems to sock manufacturers in actual production.

[0039] The following embodiments are provided to solve the above problems:

[0040] An automatic sock knitting machine with single and double paths operating simultaneously includes a knife hole tile 1 and a switching knife 2. The knife hole tile 1 is provided with a knife-shaped hole 11, and the switching knife 2 is configured to cooperate with the knife-shaped hole 11.

[0041] The switching blade 2 is configured to be a single-path automatic sock knitting machine when it does not pass through the blade hole 11; and a double-path automatic sock knitting machine when the switching blade 2 passes through the blade hole 11.

[0042] In a further embodiment of this example, the switching blade 2 is provided with a feeding device 3, which can drive the switching blade 2 to move, thereby enabling the switching blade 2 to have two working states: one without passing through the blade-shaped hole 11 and the other through the blade-shaped hole 11.

[0043] In a further embodiment of this example, an operating table 4 is also included, on which a syringe 41, a middle plate 42, and a lower plate 43 are provided;

[0044] The middle plate 42 and the lower plate 43 are respectively arranged circumferentially on the outside of the syringe 41, and the switching knife 2 and the knife hole tile 1 are respectively arranged above the middle plate 42.

[0045] In a further embodiment of this example, a plurality of knitting components are provided inside the syringe 41 through grooves, and the knitting components include knitting needles 441, jacquard needles 442, and bottom needles 443;

[0046] The jacquard needle 442 is positioned between the knitting needle 441 and the bottom needle 443, and the jacquard needle 442 has a protrusion 444.

[0047] In a further embodiment of this example, a grooved tile 421 is provided below the middle plate 42, and the grooved tile 421 is provided with a notch 422;

[0048] The notch 422 is configured such that when the protrusion 444 moves downward, it can pass through the notch 422 to ensure the movement of the jacquard needle 442.

[0049] In a further embodiment of this example, a sedative tablet 5 is also included, which is disposed above the syringe 41;

[0050] The switch plate 5 is configured such that when the switching blade 2 passes through the blade hole 11, the inclined blade surface of the switching blade 2 and the inclined surface of the blade hole 11 combine to form a long-distance downward movement trajectory of the knitting needle. The knitting needle 441 moves up and down outside the needle cylinder 41. When the needle cylinder 41 and the blade hole tile 1 make relative circular movements, the knitting needle 441 realizes a curved path movement trajectory composed of the blade hole tile 1 and the switching blade 2.

[0051] The curved path motion trajectory feeds the yarn in the needle 441 into the motion plane of the sinker 5, achieving weaving with another yarn inside the cylinder 41.

[0052] In a further embodiment of this example, a steel ring 6 and a needle selector 7 are also included. The needle selector 7 is disposed on the steel ring 6, and the steel ring 6 is disposed on the lower plate 43.

[0053] In a further embodiment of this example, the steel ring 6 is provided with a plurality of grooves, and the number of needle selectors 7 is plurality of, with the plurality of needle selectors 7 respectively disposed on the grooves of the steel ring 6.

[0054] like Figure 1 and Figure 2 As shown, the perforated tile 1 has a knife-shaped hole 11, which allows the blade head of the switching blade 2 to pass through. The switching blade 2 is fixed to the perforated tile 1 by an aluminum base, which is equipped with a pneumatic or other feeding device 3 to control the advance and retraction of the switching blade 2.

[0055] After the switching blade 2 is advanced, its inclined blade surface and the inclined surface that originally existed in the blade hole tile 1 combine to form a long downward movement trajectory of the knitting needle 441. The knitting needle 441 has a straight groove on the outside of the needle cylinder 41 that allows it to move up and down. When the needle cylinder 41 and the blade hole tile 1 make relative circular motion, the knitting needle 441 can realize a curved path movement trajectory composed of the blade hole tile 1 and the switching blade 2.

[0056] This motion trajectory feeds the yarn in the needle 441 into the motion plane of the sinker 5, thereby achieving knitting with another yarn in the cylinder 41.

[0057] like Figure 3 As shown, the upper part of the operating table 4 has a lower plate 43 and a middle plate 42. There are many components directly on these two plates. The needle selector 7 for knitting patterns is also in this area. The needle selector 7 is located on the groove surface of the curved surface of the lower steel ring 6. The number of needle selectors 7 can determine the types and features of the knitting patterns of the sock machine.

[0058] This solution allows the needle selector 7 to remain unaffected by the improved design, achieving the same number of needle selectors as the original single-channel needle selector 7 in single-channel operation.

[0059] In the prior art, the needle selector 7 has multiple installation positions and multiple needle selectors 7 are set. If the installation position of the needle selector 7 is occupied by other components, the performance of the whole machine will be reduced. Ordinary dual-channel models are limited in overall performance because the second channel needs to occupy the positions of several needle selectors 7.

[0060] The lower plate 43 and the middle plate 42 contain a needle cylinder 41 with grooves, each groove containing a knitting component.

[0061] Above the middle plate 42 is a knife-hole tile 1, which also performs some of the functions of a single-channel machine.

[0062] Once the knife is fixed on the knife hole tile 1 and can switch between forward and backward movement, the single-path machine can be converted into a dual-path machine.

[0063] like Figure 4 As shown, the knitting needle 441 slides downward along the inclined surface of the knife hole tile 1 and the switching knife 2. The jacquard needle 442 also moves downward as the knitting needle 441 moves downward. There is a grooved tile 421 at the bottom. The grooved tile 421 needs to have a small notch, i.e., a notch 422, so that the protrusion of the jacquard needle 442 can move downward smoothly. The bottom needle 443 also moves downward in the same way. The bottom needle 443 has multiple protruding teeth.

[0064] like Figure 5 and Figure 6 The image shows the groove pattern of the grooved tile 421.

[0065] like Figure 7 As shown, in addition to the inclined surface with the guide pin protrusion on the blade head of the switching blade 2, a groove is also provided, so that after the needle moves a certain distance, it enters the smooth groove and stops sliding downward, and maintains a relatively horizontal movement trajectory, allowing the upper feed wire to complete the corresponding action.

[0066] It should be noted that in this embodiment of the invention, the two tiles on the single-path machine are trimmed and an additional cutter head is added to achieve single-path / dual-path switching, which is inexpensive.

[0067] This invention introduces a second knitting thread into a single-path sock knitting machine through a simple structure. Normal double-path machines also introduce the second knitting thread through the downward movement of the needle, but this requires a complex structure, adds many parts, increases costs, and occupies a lot of space between the middle and lower discs, which greatly affects the number of needle selectors. This invention achieves the introduction of a second path through a simple method with minimal impact on the original single-path mode and very low cost.

[0068] This invention enables it to have dual-channel functionality, the modified structure is simple, and it is applicable to single-channel models that are already in mass production, making it easy to promote and apply on a large scale.

[0069] The present invention modifies the upper part of the middle plate, which has a larger space, making it easier to install and maintain, without occupying the distance of the middle and lower plates. It can introduce the second needle thread without destroying the space where the needle selector is installed, and can easily switch back to single-path mode. It can also be adjusted without affecting the number of single-path needle selectors.

[0070] It should be noted that, in this document, relational terms such as "first" and "second" are used only to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such process, method, article, or apparatus.

[0071] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention.
