Description

Technical Field

[0001] The invention relates to the field of long-pile knitting machines, in particular to a needle cylinder with a needle stabilizing mechanism, a long-pile knitting machine and a needle stabilizing method. Background Art

[0002] A long-pile knitting machine is a machine for weaving long-pile knitted fabrics, also known as an artificial fur knitting machine. On a double-needle-bed multi-bar latch needle long-pile warp knitting machine, double-layer grey cloth can be woven. The long-pile grey cloth is made by cutting the wool yarn extension line in the middle. When a long-pile grey cloth with a longer surface pile is required, the knitting needles of the long-pile knitting machine need to perform a long-distance needle withdrawal action. In order not to affect the normal knitting of the knitting needles, the needle groove completely covers the entire needle withdrawal process. The knitting needles will have a process of moving away from the needle groove. During this process, the knitting needles are prone to deflection, affecting the quality of the finished product, and even seriously affecting the knitting process. Summary of the invention

[0003] The main purpose of the present invention is to overcome the shortcomings of the prior art and provide a needle cylinder with a needle stabilizing mechanism, a long-pile knitting machine and a needle stabilizing method, which can stabilize the entire needle withdrawal process when knitting ultra-long-pile blank fabrics without affecting the normal knitting of the knitting needles.

[0004] The present invention adopts the following technical solution:

[0005] A syringe with a needle stabilizing mechanism comprises a syringe body, a needle groove and a knitting needle, wherein the needle groove is arranged on the outside of the syringe body, and the knitting needle is arranged in the needle groove. It also comprises a needle stabilizing guide ring, which is arranged on the upper end of the syringe body and coaxially arranged with the syringe body. A needle stabilizing groove is provided on the outer peripheral surface of the needle stabilizing guide ring, the needle stabilizing groove corresponds to the needle groove one by one, and the upper section of the knitting needle that has separated from the needle groove can be guided by the needle stabilizing groove, and the needle stabilizing groove is arranged so that when the upper end of the knitting needle passes through the needle stabilizing groove, its hook portion is exposed outside so as not to interfere with weaving.

[0006] Furthermore, the bottom of the needle stabilizing groove and the bottom of the needle groove are located on the same straight line, and the depth of the needle stabilizing groove is shallower than the depth of the needle groove.

[0007] Furthermore, the depth of the needle stabilizing groove is 0.8-1.2 mm.

[0008] Furthermore, a mounting seat is formed inside the syringe body, and the needle stabilizing guide ring is detachably arranged on the mounting seat by means of bolts.

[0009] Furthermore, it also includes a needle pressing plate arranged opposite to the needle stabilizing groove, wherein the needle pressing plate is arranged at the hillside position of the mountain-shaped track formed by the needle withdrawal action of the knitting needle, and the knitting can move between the needle pressing plate and the needle stabilizing groove.

[0010] Furthermore, the needle pressing plate is directly opposite to the central position of the needle stabilizing groove.

[0011] Furthermore, a circular arc-shaped transition portion is formed on the needle pressing plate.

[0012] Furthermore, the knitting needle is a knife hook needle.

[0013] A long-pile knitting machine comprises an upper needle disc and a needle cylinder with a needle stabilizing mechanism as described above, wherein the needle stabilizing guide ring is located between the needle cylinder body and the upper needle disc.

[0014] A needle stabilizing method for a long-pile knitting machine, wherein the needle withdrawal action of the knitting needle includes two processes, an upward movement process and a downward movement process, and is characterized in that: during the upward movement process, the knitting needle moves upward, and the upper end of the knitting needle disengages from the needle groove and enters the needle stabilizing groove and is guided by the needle stabilizing groove to continue moving upward, and when the head of the knitting needle is higher than the needle pressing plate, the knitting needle contacts the needle pressing plate and is guided by the needle pressing plate to enter between the needle pressing plate and the needle stabilizing groove and continue to move upward until it moves into place; during the downward movement process, the knitting needle moves downward, slowly disengages from the needle pressing plate during the movement, and is guided by the needle stabilizing groove to continue moving downward to complete the entire needle withdrawal action.

[0015] It can be seen from the above description of the present invention that, compared with the prior art, the present invention has the following beneficial effects:

[0016] First, by providing a stabilizing needle guide ring and a stabilizing needle groove on the stabilizing needle guide ring, the upper section of the knitting needle that is separated from the needle groove during the needle withdrawal process can enter the stabilizing needle groove and be guided by the stabilizing needle groove, which does not affect the knitting of the knitting needle and ensures that the knitting needle will not deflect during the knitting process;

[0017] Second, the bottom of the stabilizing needle groove and the bottom of the needle groove are located on the same straight line, so that the knitting needle can enter the stabilizing needle groove more conveniently and accurately and be guided by the stabilizing needle groove, ensuring the accuracy of the knitting process. At the same time, the depth of the stabilizing needle groove is shallower than that of the needle groove, avoiding the stabilizing needle groove affecting the knitting of the knitting needle;

[0018] Third, the depth of the needle stabilizing groove is 0.8mm to 1.2mm to ensure that when the upper end of the knitting needle passes through the needle stabilizing groove, the hook is always exposed outside the needle stabilizing groove so as not to interfere with knitting;

[0019] Fourth, the needle guide ring can be detachably arranged on the syringe. When cleaning or overhauling, the needle guide ring can be removed separately, which is convenient for cleaning and overhauling of the needle guide ring;

[0020] Fifth, the upper end of the knitting needle entering the stabilizing needle groove is restricted in the stabilizing needle groove by the needle pressing plate arranged directly opposite to the stabilizing needle groove, so as to further prevent the knitting needle from swinging;

[0021] Sixth, a circular arc transition portion is formed on the needle pressing plate, so that the upper end of the knitting needle can smoothly enter between the needle pressing plate and the needle stabilizing groove, avoiding the knitting needle from being damaged due to the rigid contact between the needle pressing plate and the needle pressing plate caused by the deflection of the knitting needle before entering the needle pressing plate;

[0022] Seventh, a mounting column is arranged on the top surface of the mountain corner mounting seat, and a needle pressing plate is arranged on the mounting column, so that the overall layout of the long-pile knitting machine is more rigorous and the space occupied is reduced.

DETAILED DESCRIPTION

[0027] The present invention is further described below through specific implementation modes.

[0028] Reference Figures 1 to 3 The present invention discloses a needle cylinder with a needle stabilizing mechanism, a long-pile knitting machine and a needle stabilizing method. The long-pile knitting machine comprises an upper needle disk 1, a needle cylinder 2 and a lower corner mounting seat 3. The lower corner mounting seat 3 is arranged opposite to the outer side of the needle cylinder 2 for mounting a knitting needle corner block. The needle cylinder 2 comprises a needle cylinder body 20, a needle groove 21, a knitting needle 22, a mounting seat 23, a needle stabilizing guide ring 24 and a needle pressing plate 25. The needle groove 21 is arranged on the outer side of the needle cylinder body 20, and the knitting needle 22 is a knife hook needle and is arranged in the needle groove 21. The needle stabilizing guide ring 24 is arranged between the upper needle disk 1 and the needle cylinder 2 and is arranged coaxially with the needle cylinder body 20. A mounting seat 23 is formed on the inner side of the needle cylinder body 20. The needle stabilizing guide ring 24 is detachably arranged on the mounting seat 23 by bolts. The needle pressing plate 25 is arranged on the lower corner mounting seat 3 and opposite to the needle stabilizing guide ring 24.

[0029] A needle stabilizing groove 240 is provided on the outer peripheral surface of the needle stabilizing guide ring 24, and the needle stabilizing groove 240 corresponds to the needle groove 21 one by one and the upper section of the knitting needle 22 that has separated from the needle groove 21 can be guided by the needle stabilizing groove 240, the bottom of the needle stabilizing groove 240 and the bottom of the needle groove 21 are located on the same straight line and the depth of the needle stabilizing groove 240 is shallower than the depth of the needle groove 21 to ensure that when the upper end of the knitting needle 22 passes through the needle stabilizing groove 240, its hook portion is exposed to the outside so as not to interfere with knitting, and the depth of the needle stabilizing groove 240 is 0.8-1.2mm, and the depth can be changed according to the actual model size of the knitting needle 22.

[0030] The needle pressing plate 25 is arranged at the center of the needle stabilizing groove 240. Figure 3The knitting needle 22 will form a mountain-shaped undulating trajectory during the entire needle-out process. The needle presser plate 25 is arranged on the hillside position of the mountain-shaped trajectory formed by the needle-out action of the knitting needle 22, and the knitting needle 22 can move between the needle presser plate 25 and the needle stabilizing groove 240. A circular arc-shaped transition portion 250 is formed on the needle presser plate 25. The transition portion 250 ensures that the knitting needle 22 can smoothly transition between the needle presser plate 25 and the needle stabilizing groove 240. A mounting column 30 is arranged on the top surface of the lower mountain corner mounting seat 3, and the needle presser plate 25 is arranged on the mounting column 30.

[0031] Continue to refer to Figures 1 to 3 When the present invention is used, when the knitting needle 22 needs to perform a long-distance needle-out action, the stabilizing needle guide ring 24 is installed on the mounting seat 23, and the needle pressing plate 25 is installed on the mounting column 30. During the needle-out process, the upper section of the knitting needle 22 detaches from the needle groove 21 and enters the stabilizing needle groove 240 and is guided by the stabilizing needle groove 240. The knitting needle 22 moves a distance in the stabilizing needle groove 240 until the head of the knitting needle 22 (the head of the knitting needle 22 includes the hook portion and the knife portion of the knife hook needle) is completely higher than the needle pressing plate 25. The knitting needle 22 contacts the transition portion 250 of the needle pressing plate 25 and is guided by the transition portion 250 to slide between the needle pressing plate 25 and the stabilizing needle groove 240 to continue the needle-out action. During the descending process, when the head of the knitting needle 22 approaches and has not yet contacted the pressure array plate 25, the knitting needle 22 detaches from the needle pressing plate 25 and continues to descend under the guidance of the stabilizing needle groove 240 until the entire needle-out action is completed.

[0032] The above is only a specific implementation of the present invention, but the design concept of the present invention is not limited to this. Any non-substantial changes to the present invention using this concept shall be deemed as an infringement of the protection scope of the present invention.
