Description

Technical Field

[0001] This invention relates to the field of textile technology, and in particular to a triangle for high-needle, high-density fabrics. Background Technology

[0002] Existing needle guide triangles typically have only one needle track, which defines the path of the needle. Therefore, different needle tracks can be used to knit different patterned fabrics. However, when knitting high-gauge, high-density fabrics, due to the small loop size and large needle latch, the upper and lower needles usually need to cooperate to help the old loop slide over the needle latch and be unhooked. For example, when the upper needle is unhooking the old loop, the lower needle moves upwards, its exit height exactly matching the height of the old loop on the upper needle, and it presses against the back of the upper needle. As the upper needle extends forward, the lower needle blocks the old loop from moving forward with it, creating a relative movement between the old loop and the upper needle. This allows the old loop to slide out of the upper needle's hook, successfully passing over the needle latch and achieving unhooking. However, when knitting some patterned fabrics, sometimes the needle does not exit, preventing the old loop on the upper needle from unhooking, thus hindering the knitting of high-gauge, high-density transfer fabrics. Therefore, existing technology needs improvement and enhancement. Summary of the Invention

[0003] In view of the shortcomings of the prior art, the purpose of the present invention is to provide a triangle for high-needle, high-density fabrics, which aims to solve the defect in the prior art that the old loops are difficult to unwind when knitting high-needle, high-density fabrics due to the small size of the loops.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] A triangular mechanism for high-needle, high-density fabrics includes a triangular base and a first triangle, a second triangle, and a third triangle located between the first and second triangles, all disposed on the triangular base. The lower edge of the first triangle and the upper edge of the third triangle form a knitting track for limiting the movement of the knitting needle. The lower edge of the third triangle and the upper edge of the second triangle form an auxiliary track for limiting the old loops in the needle to be unhooked. The auxiliary track has an upwardly protruding protrusion on the upper edge of the second triangle, which is used to lift the knitting needle upwards to assist the unhooking of the old loops in the needle.

[0006] In the triangular mechanism for high-needle, high-density fabric, the height of the protrusion is such that when the protrusion pushes the knitting needle upward, the height of the knitting needle hook is at least equal to or greater than the horizontal height of the upper needle.

[0007] In the triangular structure for the high-needle, high-density fabric, the thickness of the second triangle is greater than the thickness of the first triangle and the third triangle.

[0008] In the triangular mechanism for the high-needle, high-density fabric, the weaving track is a looping track or a tucking track.

[0009] In the triangular mechanism for high-needle, high-density fabrics, the looping track has an inverted V-shaped structure, including a needle track inlet, a loop-removing section, a padding section, a closed section, a loop-removing section, and a needle track outlet.

[0010] In the triangular mechanism for high-needle, high-density fabrics, the loop track has a trapezoidal structure, including a needle path inlet, a needle tongue opening section, a padding section, a closed section, and a needle path outlet.

[0011] In the high-needle, high-density fabric triangular mechanism, a fourth triangle is also provided on the triangular base. The upper structure of the fourth triangle is the same as the lower structure of the first triangle. The upper side of the fourth triangle is used to form a needle track. The needle track is used to limit the movement trajectory of the needle. The needle is used to drive the knitting needle.

[0012] In the triangular mechanism for high-needle, high-density fabric, the top of the top needle does not have a needle hook and abuts against the bottom of the knitting needle. The top needle is used to make the knitting needle move along the trajectory of the top needle track.

[0013] In the triangular structure for high-needle, high-density fabric, the lower side of the first triangle and the upper side of the fourth triangle are both inverted V-shaped structures, and the upper side of the third triangle is a trapezoidal structure.

[0014] In the triangular mechanism for high-needle, high-density fabric, the first triangle is also provided with a pressing point. The pressing point is located at the position of the loop-off section of the first triangle, and its position height is lower than the position height of the needle path exit.

[0015] Beneficial effects:

[0016] This invention provides a high-needle, high-density triangular mechanism. By setting a first triangle, a second triangle, and a third triangle, a knitting track for performing the knitting task and an auxiliary track for assisting the unwinding of old loops on the upper needle are formed. A protrusion is provided on the upper edge of the second triangle, allowing the needle foot to move along the auxiliary track when the needle is not performing a knitting task. This allows the top of the needle to block the old loop on the upper needle from moving towards the needle bar, thus assisting in the unwinding of the old loop on the upper needle. This triangular mechanism enables the knitting needle to unwind smaller loops regardless of whether a knitting task is being performed, thereby achieving the knitting of high-needle, high-density transfer fabrics.

Detailed Implementation

[0024] This invention provides a high-needle, high-density triangular mechanism. To make the objectives, technical solutions, and effects of this invention clearer and more explicit, the following embodiments are provided for further detailed explanation. It should be understood that the specific embodiments described herein are only for explaining this invention and are not intended to limit this invention.

They are only for the convenience of describing 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, and therefore should not be construed as a limitation of the present invention. In addition, the terms "first," "second," etc., are only used to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0026] Please see Figure 1-6This invention provides a triangular mechanism for high-needle, high-density fabrics. The triangular mechanism includes a triangular base 1 and a first triangle 2 and a second triangle 3 disposed on the triangular base 1, and a third triangle 4 located between the first triangle 2 and the second triangle 3. The lower edge of the first triangle 2 and the upper edge of the third triangle 4 form a knitting track 6 for limiting the movement of the knitting needle 8. The lower edge of the third triangle 4 and the upper edge of the second triangle 3 form an auxiliary track 7 for limiting the movement of the knitting needle 8. Furthermore, the upper edge of the second triangle 3 is provided with an upwardly protruding protrusion 12. The height of the protrusion 12 is just enough to allow the top of the knitting needle 8 to block the old loop of the upper needle. Through the blocking effect of the knitting needle 8, the old loop in the upper needle is helped to move towards the needle bar, thereby realizing loop removal.

[0027] In the specific implementation process, when the knitting needle 8 is knitting, through the action of the needle selector and sinker, the knitting needle 8 moves along the knitting track 6. During the movement, it can block the old loop of the upper needle, assisting the old loop to slide past the needle tongue 14 of the upper needle and move to the needle bar 15, thus realizing the loop release. When the knitting needle 8 is not knitting, the knitting needle 8 moves along the auxiliary track 7. The protrusion 12 set therein allows the knitting needle 8 to move upward, and the time of its upward movement corresponds exactly to the time point when the old loop of the upper needle is released. At this time, the top of the knitting needle 8 corresponds exactly to the old loop of the upper needle. By blocking the old loop with the knitting needle 8, when the upper needle moves forward again, the old loop can smoothly slide from the needle tongue 14 to the needle bar 15, thereby avoiding the situation where the old loop cannot be released due to the small loop size of the high-needle, high-density fabric, thus realizing the knitting of high-needle, high-density transfer fabric.

[0028] In existing technology, since the knitting needle 8 does not move upward when not knitting, it cannot assist in unwinding the old loop of the upper needle. However, this application provides a protrusion 12 at the second triangle 3, so that the knitting needle 8 moves along the auxiliary track 7 when not knitting. When the knitting needle 8 moves upward along the protrusion 12, it can block the old loop of the upper needle, assisting in unwinding the old loop of the upper needle. This achieves the goal of smoothly unwinding even when the loop arc is small during high-density knitting.

[0029] Specifically, such as Figure 6 As shown, the thickness of the second triangle 3 is greater than the thickness of the first triangle 2 and the third triangle 4. Therefore, when the knitting needle 8 is not performing a knitting task, its needle can still extend into the auxiliary track 7 and move along the auxiliary track 7 under the action of the second triangle 3, assisting the old loop of the upper needle to unwind. At the same time, when the knitting needle 8 is performing a knitting task, through the action of the needle selector and the sinker, the knitting needle 8 can run along the knitting track 6 to complete the knitting task.

[0030] Specifically, in the triangular mechanism described above, the time it takes for the knitting needle 8 to reach the position of the protrusion 12 is the time it takes for the old loop of the upper needle to come off the loop. The height of the protrusion 12 is such that the height of the top of the knitting needle 8 exceeds or is the same as the horizontal height of the upper needle. This is because the height of the protrusion 12 directly affects whether the knitting needle 8 can help the upper needle come off the loop. Therefore, the height of the protrusion 12 must ensure that the height of the top of the knitting needle 8 exceeds or is at least the same as the horizontal height of the upper needle. Only in this way can the top of the knitting needle 8 abut against the old loop of the upper needle when it moves along the protrusion 12, preventing it from getting stuck at the needle tongue 14. In the specific implementation process, since the upper needle moves forward when coming off the loop, when the knitting needle 8 moves upward under the action of the protrusion 12 to block the old loop, the old loop of the upper needle does not move with the upper needle, and thus the old loop slides to the needle bar 15, achieving the purpose of coming off the loop. Therefore, through the action of the protrusion 12 and the knitting needle 8, even if the loop of the high-needle, high-density fabric is very small, the old loop can still slide from the needle tongue 14 to the needle bar 15 to be unrolled due to the mutual assistance of the purl and knitting needles, thus realizing the knitting of the high-needle, high-density transfer fabric.

[0031] It should be noted that the triangular mechanism described in this embodiment of the invention can be used to limit the movement trajectory of the upper needle or the lower needle. The knitting needle 8 can be either an upper needle or a lower needle. However, for ease of distinction, in the embodiments of the present invention, the knitting needle 8 is described as a lower needle.

[0032] In the triangular mechanism described above, a protrusion 12 is provided on the upper side of the second triangle 3 to assist the old loops of the needle 8 in unwinding when it moves along the auxiliary track 7. The auxiliary track 7 is mainly used to unwind the old loops of the needle 8 even when it is not performing a knitting task. The knitting track 6 is mainly used to enable the needle 8 to perform a knitting task. The specific knitting task it can perform depends on the structure of the first triangle 2 and the third triangle 4, as detailed below:

[0033] As one implementation method, such as Figure 1 , Figure 3 As shown, the weaving track is a loop track 16, with an inverted V-shaped structure, used to achieve the loop weaving task. Specifically, as... Figure 3As shown, the looping track 16 includes, from right to left, a needle track inlet 18, a loop-removing section 20, a yarn padding section 21, a closed section 22, a loop-removing section 23, and a needle track outlet 19. In the specific implementation process, when the knitting needle 8 performs the loop knitting task, it enters through the needle path entrance 18. When it passes through the loop-removal section 20, it moves upward. During the movement, the needle tongue 14 opens, and the old loop located in the needle structure slides past the needle tongue 14 with the assistance of the upper needle. Then, the knitting needle 8 continues to move upward. When it reaches the highest point, the loop is completely removed. Then, the knitting needle 8 moves downward and enters the yarn-laying section 21. During the downward movement, it hooks and pulls the new yarn to achieve yarn-laying. Then, the knitting needle 8 continues to move downward and enters the closing section 22. During the movement, the needle tongue 14 closes. At this time, the new yarn is in the needle hook 13, and the old yarn moves upward from the needle bar 15. The knitting needle 8 continues to move downward to perform yarn bending and loop removal. The old yarn exits from the knitting needle 8, forming a loop, which is wrapped on the new yarn. The new loop is located in the closed needle hook 13. When the knitting needle 8 moves to the needle path exit 19, one loop knitting task is completed.

[0034] It should be noted that when knitting needle 8 performs the above-mentioned knitting task, it can also assist the purl needle in turning the loop when passing through the turning loop section 20. The purl needle can also assist knitting needle 8 in turning the loop. Therefore, it is possible to knit high-needle, high-density knitting fabric.

[0035] As another implementation, the woven track is a loop track 17, such as... Figure 2 As shown, its structure is approximately trapezoidal, used to achieve the task of weaving loops. Specifically, as... Figure 4 As shown, the tucking track 17 includes, from right to left, a needle path inlet 18, a needle tongue opening section 24, a tucking section 25, a closing section 22, and a needle path outlet 19. The tucking section 25 is a horizontal line, and the position height of the knitting needle 8 does not change when it passes through the tucking section 25. In specific implementation, the knitting needle 8 enters the track through the needle path inlet 18. When it passes through the needle tongue opening section 24, the knitting needle 8 moves upward, and the needle tongue 14 opens during the movement. However, the position height of the knitting needle 8 in the needle tongue opening section 24 is relatively low. Therefore, after the needle tongue 14 opens, it does not unwind the loop, and the old loop remains inside the needle hook 13. Then, the knitting needle 8 passes through the tucking section 25, where the position height of the knitting needle 8 remains unchanged, only hooking and pulling the new yarn to achieve yarn padding. After gathering the loops, the needle 8 moves downwards and enters the closed section 22. During the movement, the needle tongue 14 closes, so that both the new and old loops are inside the needle hook 13. Then it exits from the needle path exit 19, completing one gathering task.

[0036] Therefore, the above-mentioned triangular mechanism can achieve different knitting tasks by setting different knitting tracks 6. In the process of knitting, if it is necessary to unwind the loop, the upper needle and the lower needle can assist each other in unwinding the old loop, thereby realizing the knitting of high-needle, high-density transfer fabric.

[0037] In the above embodiments, while assisting in the unwinding of the old coil, either coil forming or coil gathering can be achieved during weaving, depending on the structure of the first triangle 2 and the third triangle 4. However, the above-mentioned triangle mechanism can only perform a single weaving task on the same triangle mechanism. When weaving different patterns, the triangles need to be changed, which is very troublesome. To address this problem, in some embodiments, such as... Figure 5 As shown, the triangular base 1 is also provided with a fourth triangle 5, which is located below the second triangle 3. The structure of the upper part of the fourth triangle 5 is the same as or similar to the structure of the lower part of the first triangle 2, forming a thimble track 26. The thimble track 26 is used to limit the movement trajectory of the thimble 9. The top of the thimble 9 abuts against the bottom of the knitting needle 8. Through the action of the thimble 9, the knitting needle 8 moves along the trajectory of the thimble track 26.

[0038] Specifically, the thimble 9 is positioned below the knitting needle 8. The thimble 9 does not have a needle hook 13 at its top, and its lower part has a thimble needle foot 11. The thimble needle foot 11 corresponds to the entrance of the thimble track 26, and the top of the thimble 9 abuts against the bottom of the knitting needle 8. In practice, when both the thimble 9 and the knitting needle 8 are engaged, the thimble needle foot 11 moves along the upper edge of the fourth triangle 5, while the top of the thimble 9 pushes the knitting needle 8 to move synchronously. Simultaneously, the knitting needle foot 10 is positioned between the first triangle 2 and the third triangle 4, and is restricted by the lower edge of the first triangle 2. Therefore, during movement, the thimble 9 and the knitting needle 8 are essentially constrained by the upper edge of the fourth triangle 5 and the lower edge of the first triangle 2.

[0039] More specifically, the structures of the first triangle 2, the second triangle 3, the third triangle 4, and the fourth triangle 5 are as follows: Figure 5 As shown, the lower edge of the first triangle 2 and the upper edge of the fourth triangle 5 are inverted V-shaped structures, the same shape as the aforementioned loop-forming track 16, thus enabling the knitting needle 8 to perform loop-forming knitting. The upper edge of the third triangle 4 has the aforementioned trapezoidal structure, forming a loop-forming track 17. When the knitting needle 8 moves along the upper edge of the third triangle 4, it can perform loop-forming knitting. In specific implementation, when both the top needle 9 and the knitting needle 8 are out, the top needle 9 moves along the upper edge of the fourth triangle 5, simultaneously pushing the knitting needle 8 to move along with it. At the same time, the needle foot 10 is also restricted by the lower edge of the first triangle 2. Therefore, under the action of the top needle 9, the movement trajectory of the needle foot between the first triangle 2 and the third triangle 4 is the trajectory of the loop-forming track 16, which can complete the steps of loop removal, yarn padding, closing, loop release, and loop formation, thus achieving the loop-forming knitting task. When the thimble 9 stops and the knitting needle 8 stops, the knitting needle 10 moves along the upper edge of the third triangle 4, thus completing the task of knitting in circles.

[0040] Therefore, the triangular mechanism with the fourth triangle 5 can perform multiple tasks. Specifically, when the knitting needle 8 is not knitting, the needle foot 10 moves along the upper edge of the second triangle 3. Through the action of the protrusion 12, it assists the upper needle in unwinding loops, thus achieving the goal of assisting the upper needle in unwinding loops even when the knitting needle 8 is not knitting, satisfying the knitting of high-needle, high-density fabrics. When both the knitting needle 8 and the top needle 9 are engaged, the top needle 9 moves along the upper edge of the fourth triangle 5, pushing the knitting needle 8 to perform a loop-forming knitting task. When the knitting needle 8 is engaged and the top needle 9 is not engaged, the knitting needle 8 moves along the upper edge of the third triangle 4 without the action of the top needle 9, thereby achieving a tuck-knitting task. At the same time, since the knitting needle 8 can assist the upper needle in unwinding old loops when performing both loop-forming and tuck-knitting tasks, it can achieve the knitting of high-needle, high-density transfer-loop fabrics.

[0041] In some embodiments, in order to better help the old loop of the knitting needle 8 to come off the loop, the first triangle 2 is also provided with a pressing point 27. The pressing point 27 is set at the position of the first triangle 2 corresponding to the loop-off section 23. Its position height can make the needle hook 13 of the knitting needle 8 lower than the height of the needle passage exit 19. Therefore, when the old loop comes off the loop, the needle hook 13 can move to a lower position, increasing the pulling effect of the old loop, so that the old loop can be smoothly detached from the knitting needle 8.

[0042] In summary, the high-needle, high-density triangular mechanism of the present invention, by setting a first triangle, a second triangle, and a third triangle, forms a knitting track for performing the knitting task and an auxiliary track for assisting the old loops of the upper needle to unwind. Furthermore, a protrusion is provided on the second triangle, which allows the needle foot of the knitting needle to move along the auxiliary track when the knitting needle is not performing the knitting task, and the top of the knitting needle can assist the old loops of the upper needle to unwind, thereby realizing the knitting of high-needle, high-density fabric.
