Thus, the resistance generated by the action of the scissor blade each time is relatively large, and the loop on the sinker blade has a shaping process and is not immediately cut off. The second scissor triangle block is added, the shearing action groove is cancelled, the second scissor triangle block and the first scissor triangle block are arranged in an interval and cycle, and thus the resistance generated by the scissor blade is only half of the previous resistance.

[0024] 3. The width of the reset platform of the reset triangle is increased, and the needle of the reset platform section can only maintain the previous state, so that the possibility of disorder is reduced.

[0025] 4. The improved oblique port shearing jacquard needle disc outer ring has a notch, which can better fix the bottom yarn and prevent it from swinging, so that the loop tension is stable and the fabric surface is flat. BRIEF DESCRIPTION OF DRAWINGS

[0040] The present application will be further described in conjunction with the drawings and specific embodiments.

[0041] Reference Figures 5-14The embodiment of the present application discloses a new automatic shearing loop pile jacquard machine, which comprises a rack (not shown in the figure), a lower bottom plate 1 arranged on the rack, a lower gear 17 arranged on one side of the lower bottom plate 1, a lower cam seat 21 arranged on the lower bottom plate 1, a lower cam 23 arranged on the inner side of the lower cam seat 21, a needle cylinder 12 arranged on one side of the lower bottom plate 1, a gauze piece 13 arranged on the needle cylinder 12, a shearing blade 24 matched with the gauze piece 13, a shearing cam 6 matched with the shearing blade 24, a needle disc 11 arranged above the needle cylinder 12, a needle 8 arranged on the needle disc 11, an upper cam seat 9 arranged above the needle 8, an upper cam 10 arranged on the upper cam seat 9 and matched with the needle 8, and a yarn feeding rod 712 arranged above the needle 8 on the rack.

[0042] Reference Figure 7 The end face of the needle disc 11 close to the shearing cam seat 4 is a needle disc opening, the needle disc opening has a notch 30, after the bottom yarn m and the loop yarn m are hooked by the needle 8, the other end of the bottom yarn m is hooked on the notch 30 of the end face of the needle disc 11 close to the shearing cam seat 4, the existence of the notch 30 acts on the bottom yarn m, the stability of the bottom yarn m is greatly improved, even if the gauze piece 13 swings up and down, but one end of the bottom yarn m is hooked by the needle 8, and the other end is hooked on the notch 30 of the needle disc 11, compared with the prior art, the bottom yarn m is more stable, the tightness of the loop is more uniform, and the flatness of the cloth surface is further improved.

[0043] In the embodiment of the present application, the notch 30 of the needle disc 11 is inverted conical, and the angle F between one side of the notch and the side surface of the needle disc opening is 30°-50° Figure 7 ).

[0044] Based on the above scheme, the notch 30 can also be C-shaped.

[0045] The needle cylinder 12 is arranged on the rack, and the gauze ring 32 is arranged on the needle cylinder 12. Figure 4 In the prior art, the upper end face of the needle cylinder 12 is flush with the upper end face of the gauze ring 32, which is a common setting for those skilled in the art and is a conventional setting in the field, the upper end of the needle cylinder 12 is a needle cylinder opening 31, the top of the needle cylinder opening 31 is a flat surface, and Figure 3 A channel is formed between the needle cylinder 12 and the needle disc 11, a blowing gas nozzle 5 is arranged on the rack, the channel is located on the air duct of the airflow blown by the blowing gas nozzle 5, and the generated lint is blown away from the channel through the airflow of the blowing gas nozzle 5 during the production process.

[0046] The inverted conical notch 30 can make the inlet cross section of the channel larger than the outlet cross section, the larger inlet cross section facilitates the airflow blown by the blowing gas nozzle 5 to enter the channel, and the smaller cross section at the outlet end can increase the flow rate of the air, so that the effect of blowing away the lint is better.

[0047] In this embodiment, the upper end surface of the needle cylinder 12 is lowered so that the height difference E between the upper end surface of the needle cylinder 12 and the upper end surface of the gill ring 32 is 2-4 mm. In this embodiment, the height difference is 2 mm.

[0048] As shown in the figure, the angle C between the top inclined surface of the needle cylinder 12 and the side of the needle cylinder 12 close to the gill ring 32 is 30°-60°, and in this embodiment, the angle is 45°. The width of the horizontal section D of the needle cylinder port 31 at the top of the needle cylinder 12 is 0.3-2 mm, and in this embodiment, the width is 0.6 cm.

[0049] By lowering the height of the upper end surface of the needle cylinder 12, the channel is expanded, and the lint is more easily blown out of the channel. In combination with the inverted conical notch 30, the channel is further expanded.

[0050] Reference Figure 8 In the prior art, the scissor triangle ring 6 is composed of a plurality of first scissor triangle blocks 2, and forms a circular ring. The first scissor triangle block 2 is provided with a first guide groove 25, and the first guide groove 25 is provided with a cutting action groove 26. When the cutter blade 24 moves into the cutting action groove 26, the cutter blade 24 is actuated to cut the loop.

[0051] In actual production, the resistance generated by the action of the cutter blade each time is relatively large. The loop on the gill blade has a shaping process, and the newly generated loop does not need to be cut immediately.

[0052] The scissor triangle ring 6 of the present application is composed of a first scissor triangle block 2 and a second scissor triangle block 27. The second scissor triangle block 27 is provided with a first guide groove 25, and the cutting action groove 26 is cancelled. The first scissor triangle block 2 and the second scissor triangle block 27 are arranged in sequence and at intervals, and form a circular ring-shaped scissor triangle ring 6.

[0053] When the cutter blade 24 moves on the scissor triangle ring 6, it will move through the first guide groove 25 on the first scissor triangle block 2 and the first guide groove 25 on the second scissor triangle block 27 in sequence. Only when it moves in the first guide groove 25 of the first scissor triangle block 2 will it be guided by the cutting action groove 26. Therefore, the running resistance can be greatly reduced, energy consumption can be reduced, and the service life of the cutter blade 24 can be improved. Since the shaping process is not immediately required for the newly generated loop, the interval between the cutter blade 24 and the second scissor triangle block 27 will not affect the cutting of the loop, and will not reduce the production quality.

[0054] Reference Figure 4, In the prior art, the rack is provided with a lower triangular seat 21, a plurality of reset triangles 22 are arranged on the lower triangular seat 21, a second guide groove 28 is formed on the reset triangle 22, the reset triangle 22 has a reset platform 29 on the second guide groove 28, a lower needle cylinder 15 is arranged on the rack, a jacquard piece 16 is movably arranged on the lower needle cylinder 15, an intermediate piece 14 is movably arranged on the needle cylinder 12, the lower end of the intermediate piece 14 is linked with the upper end of the jacquard piece 16, and the upper end of the intermediate piece 14 is linked with the lower end of the gauze piece 13.

[0055] The upper end of the jacquard piece 16 is provided with a slide column, the slide column can walk in the reset triangle 22, when walking to the section of the second guide groove 28 located on the reset platform 29, the jacquard piece 16 acts, drives the intermediate piece 14, and further drives the gauze piece 13 to act.

[0056] Further, in order to increase the stability of the gauze piece 13, the width of the reset platform 29 is increased from 13.28mm in the prior art to 20-28mm, and the embodiment of the present application adopts 26.82mm.

[0057] The reset platform 29 of the reset triangle 22 is widened, when the jacquard piece 16 walks in the section of the second guide groove 28 located on the reset platform 29, the gauze piece 13 can only maintain the previous state, so that the possibility of disorder is reduced.
