Furthermore, the terms "first," "second," and the like are used solely to distinguish one from another, and are not to be construed as indicating or implying relative importance.

Please refer to fig. 1-6, the utility model provides a high-density surface fabric of high needle is with triangle mechanism, triangle mechanism includes triangle base 1 and sets up first triangle 2, second triangle 3 on triangle base 1 to and be located the third triangle 4 between first triangle 2 and the second triangle 3, the lower limit of first triangle 2 and the synthetic knitting track 6 that is used for injecing the motion of knitting needle 8 of the last side of third triangle 4, the lower limit of third triangle 4 and the synthetic auxiliary track 7 that is used for injecing the motion of knitting needle 8 of the last side of second triangle 3, and, the higher limit of second triangle 3 is equipped with upwards convex arch 12, the height of arch 12 just enables the top of knitting needle 8 to block the old coil of last needle, through the effect of blockking of knitting needle 8, helps the old coil in the last needle to move toward the needle bar direction, realizes moving back the circle.

In the specific implementation process, when the knitting needle 8 carries out knitting, the knitting needle 8 moves along the knitting track 6 under the action of the needle selector and the sinker, and can abut against an old coil of an upper needle in the moving process to assist the old coil to slide over a latch 14 of the upper needle and move to a needle rod 15, so that the coil is withdrawn. When the knitting needle 8 does not knit, the knitting needle 8 moves along the auxiliary track 7, the arranged bulge 12 enables the knitting needle 8 to move upwards, the upward movement time of the upward movement time exactly corresponds to the time point of the returning of the old loop of the upper needle, at the moment, the top end of the knitting needle 8 exactly corresponds to the old loop of the upper needle, the old loop is blocked by the knitting needle 8, when the upper needle moves forwards again, the old loop can smoothly slide to the needle rod 15 from the latch 14, and therefore the situation that the old loop cannot return due to the small loop of the high-needle high-density fabric is avoided, and the high-needle high-density transferring fabric knitting is realized.

In the prior art, the knitting needle 8 does not move upwards when not knitting, so that the old stitch on the knitting needle cannot be backed up. In the application, the bulge 12 is arranged at the second cam 3, so that the knitting needle 8 moves along the auxiliary track 7 when not performing a knitting task, and when the knitting needle 8 moves upwards along the bulge 12, the knitting needle 8 can block an old upper needle coil and assist the old upper needle coil to withdraw, and the purpose of successfully withdrawing the coil even if the coil arc is small during high-needle high-density knitting is achieved.

Specifically, as shown in fig. 6, since the thickness of the second cam 3 is larger than the thickness of the first cam 2 and the third cam 4, when the knitting needle 8 does not perform a knitting task, the needle foot still extends into the auxiliary track 7, and moves along the auxiliary track 7 by the upper side of the second cam 3 to assist the old loop of the upper needle to withdraw. Meanwhile, when the knitting needle 8 carries out a knitting task, the knitting needle 8 can run along the knitting track 6 under the action of the needle selector and the sinker, so that the knitting task is realized.

Specifically, in the cam mechanism with the above structure, the time when the knitting needle 8 moves to the position of the protrusion 12 is the time when the old loop of the upper needle is knocked over, and the position height of the protrusion 12 on the cam base is the position height of the top of the knitting needle 8 exceeding or being the same as the horizontal height of the upper needle when the protrusion jacks up the knitting needle. This is because the height of the projection 12 directly affects whether the needle 8 can help the needle to withdraw the loop, and therefore the height of the projection 12 ensures that the top of the needle 8 exceeds or at least is the same as the level of the needle, only so that when the needle 8 moves along the projection 12 does the top of the needle 8 abut against the old loop of the needle, so that it does not catch on the latch 14. In the specific implementation process, as the upper needle moves forwards when withdrawing the loop, the knitting needle 8 moves upwards under the action of the protrusion 12 to block the old loop, so that the old loop of the upper needle does not move along with the upper needle, and the old loop slides to the needle rod 15, thereby achieving the purpose of withdrawing the loop. Therefore, even if the loop of the high-needle high-density fabric is very small through the action of the bulge 12 and the knitting needle 8, the old loop can still slide to the needle rod 15 from the latch 14 to retreat due to the mutual assistance of the upper needle and the lower needle, and the high-needle high-density loop transfer fabric is knitted.

It should be noted that, in the embodiment of the present invention, the triangular mechanism may be used to define a motion trajectory of an upper needle, and may also be used to define a motion trajectory of a lower needle, and the knitting needle 8 may be the upper needle, and may also be the lower needle. However, in order to facilitate differentiation, in the embodiment of the present invention, the knitting needle 8 is a lower needle.

In the cam mechanism with the structure, the bulge 12 is arranged on the upper edge of the second cam 3, so that the old loop of the knitting needle can be assisted to withdraw when the knitting needle 8 moves along the auxiliary track 7. The auxiliary track 7 with the above structure is mainly used for the old loop of the upper needle to be withdrawn when the knitting needle 8 does not perform a knitting task, and the knitting track 6 is mainly used for enabling the knitting needle 8 to perform a knitting task, specifically what kind of knitting task can be realized, and is related to the structures of the first cam 2 and the third cam 4, and specifically as follows:

as one embodiment, as shown in fig. 1 and 3, the knitting track is a knitting track 16, which has an inverted V-shaped structure and is used for knitting a loop. Specifically, as shown in fig. 3, the looping track 16 includes, from right to left, a needle path inlet 18, a loop removing section 20, a yarn laying section 21, a closed section 22, a loop releasing section 23, and a needle path outlet 19. In the specific implementation process, when the knitting needle 8 performs a looping knitting task, the knitting needle enters from a needle track inlet 18 and moves upwards when passing through a loop withdrawing section 20, in the moving process, a latch 14 is opened, and an old coil in a needle structure slides over the latch 14 under the auxiliary action of an upper needle; then, the knitting needle 8 continues to move upwards, when the knitting needle reaches the highest position, the loop retreating is completely realized, then, the knitting needle 8 moves downwards, enters the yarn padding section 21, and hooks and pulls new yarns in the downward movement process to realize the yarn padding; the knitting needle 8 then continues to move downwards, enters the closed section 22, and during the movement, the latch 14 is closed, at this time, the new yarn is in the hook 13, and the old yarn is moved upwards by the needle bar 15; the knitting needle 8 continues to move downwards to perform yarn bending and doffing, the old yarn is withdrawn from the knitting needle 8 to form a loop to be sleeved on the new yarn, the new loop is positioned in the closed needle hook 13, and when the knitting needle 8 moves to the needle passage outlet 19, a looping knitting task is completed.

It should be noted that, when the knitting needle 8 performs the knitting task, the upper needle can also assist in the retreating of the upper needle while the upper needle can also assist in the retreating of the knitting needle 8 when passing through the retreating section 20, and therefore, the knitting of the high-needle high-density loop transfer fabric can be performed.

As another embodiment, the knitting track is a tuck track 17, as shown in fig. 2, which has an approximately trapezoidal structure for realizing the tuck knitting task. Specifically, as shown in fig. 4, the tucking track 17 includes a needle track inlet 18, a latch opening section 24, a tucking section 25, a closing section 22, and a needle track outlet 19, which are sequentially arranged from right to left, the tucking section 25 is a horizontal transverse line, and the position height of the knitting needle 8 is not changed when passing through the tucking section 25. In the specific implementation process, the knitting needle 8 enters the track from the needle track inlet 18, when the knitting needle passes through the latch opening section 24, the knitting needle 8 moves upwards, the latch 14 is opened in the moving process, however, the position height of the knitting needle 8 in the latch opening section 24 is lower, so that the knitting needle 14 does not perform stitch withdrawal after being opened, an old loop is still in the needle hook 13, then, the knitting needle 8 passes through the tucking section 25, the position height of the knitting needle 8 in the tucking section 25 is unchanged, only new yarn is hooked, and yarn padding is realized. After tucking, the knitting needle 8 moves downwards, enters the closed section 22, and the latch 14 is closed in the moving process, so that the new coil and the old coil are both positioned in the needle hook 13, and then the new coil and the old coil are moved out from the needle channel outlet 19, and a tucking task is completed.

Therefore, the triangular mechanism can realize different knitting tasks by arranging the knitting tracks 6 with different structures, and in the knitting process, if loops need to be withdrawn, the upper needle and the lower needle can mutually assist the old loops to withdraw, so that the knitting of the high-needle high-density loop transfer fabric is realized.

In the above embodiment, any one of knitting for the stitch forming and tucking task can be realized while assisting the old stitch in the stitch withdrawal, specifically depending on the structures of the first cam 2 and the third cam 4. However, the cam mechanism can only realize one single knitting task on the same cam mechanism, and when different patterns are knitted, the cam needs to be replaced, which is very troublesome. In order to solve this problem, in some embodiments, as shown in fig. 5, a fourth cam 5 is further disposed on the cam base 1, the fourth cam 5 is disposed below the second cam 3, and the upper side of the fourth cam 5 has a structure identical to or similar to that of the lower side of the first cam 2, so as to form an ejector pin track 26, the ejector pin track 26 is used for defining a motion track of an ejector pin 9, the top of the ejector pin 9 is abutted against the bottom of the knitting needle 8, and the knitting needle 8 is moved along the track of the ejector pin track 26 by the action of the ejector pin 9.

Specifically, thimble 9 sets up in the below of knitting needle 8, and thimble 9 top is not equipped with hook 13, and the lower part of thimble 9 is equipped with thimble stitch 11, thimble stitch 11 corresponds the entry of thimble track 26, and the top of thimble 9 and the bottom butt of knitting needle 8. In a specific implementation process, when the thimble 9 and the knitting needle 8 are both withdrawn, the thimble pin 11 moves along the upper side of the fourth cam 5, the top of the thimble 9 pushes the knitting needle 8 to move synchronously, meanwhile, the knitting needle pin 10 is positioned between the first cam 2 and the third cam 4 and is limited by the lower side of the first cam 2, and further, in the movement process, the thimble 9 and the knitting needle 8 are limited by the upper side of the fourth cam 5 and the lower side of the first cam 2.

More specifically, the first cam 2, the second cam 3, the third cam 4 and the fourth cam 5 are structured as shown in fig. 5, wherein the lower side of the first cam 2 and the upper side of the fourth cam 5 are inverted V-shaped structures, and the shapes thereof are the same as the aforementioned knitting tracks 16, so that the knitting needles 8 can be knitted for knitting stitches. The upper side of the third cam 4 is in a trapezoidal structure as described above, and the formed track is a tucking track 17, so that the tucking knitting task can be realized when the knitting needle 8 moves along the upper side of the third cam 4. In the specific implementation process, when the thimble 9 and the knitting needle 8 are both withdrawn, the thimble 9 moves along the upper side of the fourth cam 5 and pushes the knitting needle 8 to move along with the thimble, and meanwhile, the stitch 10 of the knitting needle is limited by the lower side of the first cam 2, so that under the action of the thimble 9 of the knitting needle 8, the motion track of the stitch between the first cam 2 and the third cam 4 is the track of the looping track 16, and the steps of looping back, padding, closing, knocking over and looping can be completed, and the looping knitting task is realized. When the thimble 9 does not discharge the needle and the knitting needle 8 discharges the needle, the stitch 10 of the knitting needle moves along the upper side of the third cam 4, thereby realizing the tuck knitting task.

Therefore, the triangle mechanism provided with the fourth triangle 5 can complete various work tasks, and specifically comprises the following steps: when the knitting needle 8 does not carry out a knitting task, the stitch 10 of the knitting needle moves along the upper side of the second cam 3, and the action of the bulge 12 can assist the upper needle in returning the loops, so that the purpose that when the knitting needle 8 does not carry out the knitting task, the upper needle can still be assisted in returning the loops is achieved, and the knitting of high-needle high-density fabrics is met. When the knitting needle 8 and the thimble 9 are both out of the knitting needle, the thimble 9 moves along the upper side of the fourth cam 5 to push the knitting needle 8 to perform the knitting task. And when the knitting needle 8 is out of the needle and the thimble 9 is not out of the needle, the knitting needle 8 moves along the upper side of the third cam 4 under the condition of not acting the thimble 9, and then the tuck knitting task is realized. Meanwhile, the knitting needle 8 can assist the old loops of the upper needle in retreating when performing the tasks of knitting and tucking, so that the knitting of the high-needle high-density loop transfer fabric can be realized.

In some embodiments, in order to better assist the old loop of the knitting needle 8 in the doffing, the first cam 2 is further provided with a needle pressing point 27, and the needle pressing point 27 is arranged at a position of the first cam 2 corresponding to the doffing section 23, and the position of the needle pressing point 27 is such that the hook 13 of the knitting needle 8 is lower than the needle track outlet 19, so that when the old loop is doffed, the hook 13 can move to a lower position, the pulling effect of the old loop is increased, and the old loop can be smoothly separated from the knitting needle 8.
