Description

Technical Field

[0001] The invention relates to the field of textile machinery, in particular to an edge group of a circular knitting machine and a circular knitting machine. Background Art

[0002] Knitted air layer fabrics are comfortable to the touch, fluffy and soft, wick away sweat and keep warm, and are moisture-absorbent and breathable. They are widely used in the preparation of sportswear, casual wear, and professional wear. As an air layer fabric with excellent performance, the "Five-in-One" type of knitted air layer fabric came into being. Fig.17 The "five-piece" knitted air layer fabric shown in the figure forms a surface layer, a sub-surface layer, a hollow layer, a sub-inner layer and an inner layer in sequence from the surface to the inside.

[0069] See also Figure 1 An embodiment of the present invention provides a tuck pressing piece 10 for a circular knitting machine. The tuck pressing piece 10 comprises a tuck pressing portion 11, a tuck introducing portion 12 and a tuck pressing piece mounting portion 13. The tuck pressing portion 11 and the tuck introducing portion 12 are located at the same end of the tuck pressing piece mounting portion 13. The tuck pressing portion 11 forms a tuck pressing plane 1101 on one side away from the tuck pressing piece mounting portion 13, and the tuck introducing portion 12 forms a tuck introducing curved surface 1201 on one side away from the tuck pressing piece mounting portion 13. The tuck introducing curved surface 1201 is bent toward the tuck pressing piece mounting portion 13, and the tuck pressing plane 1101 is smoothly connected to the tuck introducing curved surface 1201.

[0070] In the tuck yarn pressing piece 10 of the present embodiment, the movement trajectory of the yarn can be limited during the tuck process mainly through the cooperation of the tuck introduction part 12 and the tuck yarn pressing part 11, thereby reducing the risk of the coil floating. Specifically, through the cooperation of the tuck introduction curved surface 1201 and the tuck yarn pressing plane 1101, the yarn smoothly transitions to the yarn pressing plane 1101 along the introduction curved surface 1201, and maintains a stable position state under the action of the yarn pressing plane, which is conducive to good control of the position of the yarn, reducing the risk of the coil floating, and improving the quality of the fabric.

[0071] Furthermore, during use of the tuck yarn pressing piece 10 in this embodiment, the tuck yarn pressing portion 11, the tuck yarn introducing portion 12 and the tuck yarn pressing piece mounting portion 13 cooperate with each other to support each other, are not easily deformed during processing, can maintain a stable structure, and are conducive to improving the stability of the tuck yarn.

[0072] It is understood that the "plane" and "curved surface" in the present invention refer to two types of surfaces. A "plane" can be understood as a surface with the same slope at all locations, and a "curved surface" can be understood as a surface with a certain curvature.

[0073] In a specific example, the loop pressing piece 10 is composed of a loop pressing portion 11, a loop introducing portion 12 and a loop pressing piece mounting portion 13, the loop pressing portion 11 and the loop introducing portion 12 are located at the same end of the loop pressing piece mounting portion 13; the side of the loop pressing portion 11 away from the loop pressing piece mounting portion 13 forms a loop pressing plane 1101, the side of the loop introducing portion 12 away from the loop pressing piece mounting portion 13 forms a loop introducing curved surface 1201, the loop introducing curved surface 1201 is bent toward the loop pressing piece mounting portion 13, and the loop pressing plane 1101 is smoothly connected to the loop introducing curved surface 1201.

[0074] In a specific example, the tuck yarn pressing plane 1101 is tangent to the tuck introduction curved surface 1201. At this time, the tuck yarn pressing plane 1101 and the tuck introduction curved surface 1201 can have a better smooth transition, so that the yarn moves smoothly along the tuck yarn pressing plane 1101 and the tuck introduction curved surface 1201, further improving the quality of the tuck.

[0075] Please refer again Figure 1 , the tuck yarn pressing part 11 extends toward one side of the tuck yarn pressing piece mounting part 13, and the tuck yarn introduction part 12 extends toward the other side of the tuck yarn pressing piece mounting part 13. At this time, a clearance area is formed between the extended end of the tuck yarn pressing part 11 and the tuck yarn pressing piece mounting part 13, and a clearance area is formed between the extended end of the tuck yarn introduction part 12 and the tuck yarn pressing piece mounting part 13. In this way, the neatness of the installation can be improved, and other components in the circular knitting machine are prevented from interfering with the tuck yarn pressing piece 10.

[0076] Furthermore, the distance between the end of the tuck yarn pressing portion 11 away from the tuck yarn pressing piece mounting portion 13 and the tuck yarn pressing piece mounting portion 13 is 5 cm to 10 cm. Figure 1 The distance range represented by a in the figure is 5 cm to 10 cm. Within this distance range, the tuck pressing piece 10 is better adapted to the length of the tuck yarn to maintain stable tuck. Optionally, the distance between the end of the tuck pressing portion 11 away from the tuck pressing piece mounting portion 13 and the tuck pressing piece mounting portion 13 is 5 cm, 6 cm, 7 cm, 8 cm, 9 cm or 10 cm.

[0077] Furthermore, an end surface 1102 of the tuck yarn pressing portion 11 away from the tuck yarn pressing piece mounting portion 13 is perpendicular to the tuck yarn pressing plane 1101 .

[0078] In a specific example, the distance between the end of the tuck introduction portion 12 away from the tuck pressing piece installation portion 13 and the tuck pressing piece installation portion 13 is 2 cm to 5 cm. Figure 1The distance range represented by b in the figure is 2 cm to 5 cm. Within this distance range, the tuck introduction part 12 stably introduces the yarn, further improving the stability of the tuck. Optionally, the distance between the end of the tuck introduction part 12 away from the tuck pressing piece installation part 13 and the tuck pressing piece installation part 13 is 2 cm, 2.5 cm, 3 cm, 3.5 cm, 4 cm, 4.5 cm or 5 cm.

[0079] Optionally, the extended end of the tuck yarn pressing portion 11 is smoothly connected to the tuck yarn pressing piece mounting portion 13, and the extended end of the tuck yarn introducing portion 12 is smoothly connected to the tuck yarn pressing piece mounting portion 13. In this way, the force of the yarn on the tuck yarn pressing portion 11 can be effectively dispersed, so that the tuck yarn pressing piece 10 maintains better structural stability.

[0080] Furthermore, a surface of the tuck yarn pressing portion 11 close to the tuck yarn pressing piece mounting portion 13 is flush with a surface of the tuck yarn introducing portion 12 close to the tuck yarn pressing piece mounting portion 13 .

[0081] In a specific example, the tuck pressing piece installation portion 13 is provided with a through hole 1301, and the through hole 1301 is used to install the tuck pressing piece 10 of the circular knitting machine. For example, the tuck pressing piece 10 is installed on the circular knitting machine through the through hole 1301.

[0082] Further, the through hole 1301 has a clearance space for adjusting the installation position of the circular knitting machine tuck yarn pressing piece 10. The through hole 1301 is provided with the clearance space, and the installation position of the tuck yarn pressing piece 10 can be conveniently controlled.

[0083] In a specific example, the tuck yarn pressing portion 11, the tuck introduction portion 12 and the tuck yarn pressing piece installation portion 13 are an integrally formed structure. This is convenient for processing and molding, and is also conducive to maintaining a stable structure of the tuck yarn pressing piece 10. Optionally, the tuck yarn pressing portion 11 is a hard tuck yarn pressing portion 11, and the tuck introduction portion 12 is a hard tuck introduction portion 12.

[0084] In a specific example, the thickness of the tuck yarn pressing portion 11 is 0.5 cm to 1 cm, and the thickness of the tuck yarn introduction portion 12 is 0.5 cm to 1 cm. For example, the thickness of the tuck yarn pressing portion 11 may be, but not limited to, 0.5 cm, 0.6 cm, 0.7 cm, 0.8 cm, 0.9 cm or 1 cm. The thickness of the tuck yarn introduction portion 12 may be, but not limited to, 0.5 cm, 0.6 cm, 0.7 cm, 0.8 cm, 0.9 cm or 1 cm. Further, the thickness of the tuck yarn pressing portion 11 is equal to the thickness of the tuck yarn introduction portion 12. Furthermore, the thickness of the tuck yarn pressing portion 11, the thickness of the tuck yarn introduction portion 12, and the thickness of the tuck yarn pressing piece mounting portion 13 are all equal. At this time, the tuck yarn pressing piece 10 maintains an overall uniform thickness.

[0085] In a specific example, the tuck yarn pressing plane 1101 is a smooth plane, and the tuck introduction curved surface 1201 is a smooth curved surface.

[0086] Another embodiment of the present invention provides a yarn pressing device, which includes a tuck-in yarn pressing piece 10.

[0087] Another embodiment of the present invention provides a circular knitting machine, which includes a tuck-in yarn pressing piece 10.

[0088] See also Figure 2 An embodiment of the present invention provides a circular knitting machine loop pressing piece 20. The loop pressing piece 20 includes a loop pressing portion 21 and a loop pressing piece mounting portion 22, wherein the loop pressing portion 21 is located at one end of the loop pressing piece mounting portion 22; a side of the loop pressing portion 21 away from the loop pressing piece mounting portion 22 forms a first sub-yarn pressing plane 2101, a transition curved surface 2102, and a second sub-yarn pressing plane 2103 connected in sequence, wherein the first sub-yarn pressing plane 2101 is parallel to the second sub-yarn pressing plane 2103, the first sub-yarn pressing plane 2101 protrudes from the second sub-yarn pressing plane 2103, and the first sub-yarn pressing plane 2101 and the second sub-yarn pressing plane 2103 are respectively smoothly connected to the transition curved surface 2102.

[0089] In the looping yarn pressing piece 20 of this embodiment, the movement trajectory of the yarn is limited mainly by the cooperation of the first sub-yarn pressing plane 2101, the transition curved surface 2102 and the second sub-yarn pressing plane 2103. In this way, during the looping process, the trajectory of the yarn and the looping path can be well buffered, and the trajectory of the yarn is adjusted to a certain extent by the transition curved surface 2102, and the tension of the yarn is appropriately released. In this way, while improving the stability of the looping, the problem of holes in the fabric during the looping process can be effectively avoided, thereby improving the yield rate and quality of the fabric.

[0090] In a specific example, the height of the first sub-yarn pressing plane 2101 protruding from the second sub-yarn pressing plane 2103 is 1 mm to 9 mm. Figure 2 The distance range represented by c is 1 mm to 9 mm. Optionally, the height of the first sub-yarn pressing plane 2101 protruding from the second sub-yarn pressing plane 2103 is 1 mm, 2 mm, 3 mm, 4 mm, 5 mm, 6 mm, 7 mm, 8 mm or 9 mm. If the height of the first sub-yarn pressing plane 2101 protruding from the second sub-yarn pressing plane 2103 is too small, it is difficult to achieve a good transition effect, and if the height is too large, it may cause excessive displacement of the yarn, which has an adverse effect on loop formation.

[0091] In a specific example, the first sub-yarn pressing plane 2101 is tangent to the transition curved surface 2102, and the second sub-yarn pressing plane 2103 is tangent to the transition curved surface 2102. At this time, the yarn can transition more smoothly between the first sub-yarn pressing plane 2101 and the transition curved surface 2102, and between the transition curved surface 2102 and the second sub-yarn pressing plane 2103, effectively ensuring the loop quality of the yarn.

[0092] Furthermore, the distance between the end of the looping yarn pressing portion 21 away from the looping yarn pressing piece mounting portion 22 and the looping yarn pressing piece mounting portion 22 is 5 cm to 10 cm. Figure 2 The distance range represented by d in the figure is 5 cm to 10 cm. Within this distance range, the looping pressing piece 20 is better adapted to the length of the looping yarn to maintain stable looping. Optionally, the distance between the end of the looping pressing piece 21 away from the looping pressing piece mounting part 22 and the looping pressing piece mounting part 22 is 5 cm, 6 cm, 7 cm, 8 cm, 9 cm or 10 cm.

[0093] Furthermore, an end surface 2104 of the loop-forming yarn pressing portion 21 away from the loop-forming yarn pressing piece mounting portion 22 is perpendicular to the first sub-yarn pressing plane 2101 .

[0094] In a specific example, the looping yarn pressing piece 20 further includes a looping introduction portion 23, and the looping introduction portion 23 and the looping yarn pressing portion 21 are located at the same end of the looping yarn pressing piece mounting portion 22; the looping introduction portion 23 forms a looping introduction curved surface 2301 on a side away from the looping yarn pressing piece mounting portion 22, and the looping introduction curved surface 2301 is bent toward the looping yarn pressing piece mounting portion 22; the looping introduction curved surface 2301 is smoothly connected to the first sub-yarn pressing plane 2101. Through the arrangement of the looping introduction portion 23, the yarn can enter the yarn pressing position of the looping yarn pressing piece 20 more stably, thereby improving the stability of the looping. Optionally, the looping introduction curved surface 2301 is tangent to the first sub-yarn pressing plane 2101.

[0095] In a specific example, the looping yarn pressing portion 21 extends toward one side of the looping yarn pressing piece mounting portion 22, and the looping introduction portion 23 extends toward the other side of the looping yarn pressing piece mounting portion 22. At this time, a clearance area is formed between the extended end of the looping yarn pressing portion 21 and the looping yarn pressing piece mounting portion 22, and a clearance area is also formed between the extended end of the looping introduction portion 23 and the looping yarn pressing piece mounting portion 22, which facilitates the installation of the looping yarn pressing piece 20 and the coordination with other components.

[0096] Furthermore, the distance between the end of the loop introduction part 23 away from the loop pressing piece installation part 22 and the loop pressing piece installation part 22 is 2 cm to 5 cm. Figure 2The distance range represented by e in the figure is 2 cm to 5 cm. Within this distance range, the loop introduction part 23 introduces the yarn stably, further improving the stability of the loop. Optionally, the distance between the end of the loop introduction part 23 away from the loop pressing piece installation part 22 and the loop pressing piece installation part 22 is 2 cm, 2.5 cm, 3 cm, 3.5 cm, 4 cm, 4.5 cm or 5 cm.

[0097] In a specific example, the extended end of the looping yarn pressing part 21 is smoothly connected to the looping yarn pressing piece mounting part 22, and the extended end of the looping introduction part 23 is smoothly connected to the looping yarn pressing piece mounting part 22. In this way, the force of the yarn on the looping yarn pressing part 21 can be effectively dispersed, so that the looping yarn pressing part 21 maintains better stability.

[0098] Further, a surface of the looping yarn pressing portion 21 close to the looping yarn pressing piece mounting portion 22 is flush with a surface of the looping yarn introducing portion 23 close to the looping yarn pressing piece mounting portion 22 .

[0099] In a specific example, the loop pressing piece installation part 22 is provided with a through hole 2201, and the through hole 2201 is used to install the circular knitting machine loop pressing piece 20. For example, the loop pressing piece 20 is installed on the circular knitting machine through the through hole 2201.

[0100] Further, the through hole 2201 has a clearance space for adjusting the installation position of the circular knitting machine loop pressing piece 20. The through hole 2201 is provided with the clearance space, and the installation position of the loop pressing piece 20 can be conveniently controlled.

[0101] In a specific example, the looping yarn pressing part 21, the looping introduction part 23 and the looping yarn pressing sheet mounting part 22 are an integrally formed structure. This is convenient for processing and molding, and is also conducive to maintaining a stable structure of the looping yarn pressing sheet 20. Optionally, the looping yarn pressing part 21 is a hard looping yarn pressing part 21, and the looping introduction part 23 is a hard looping introduction part 23.

[0102] In a specific example, the thickness of the loop pressing yarn portion 21 is 0.5 cm to 1 cm, and the thickness of the loop introduction portion 23 is 0.5 cm to 1 cm. For example, the thickness of the loop pressing yarn portion 21 may be, but not limited to, 0.5 cm, 0.6 cm, 0.7 cm, 0.8 cm, 0.9 cm or 1 cm. The thickness of the loop introduction portion 23 may be, but not limited to, 0.5 cm, 0.6 cm, 0.7 cm, 0.8 cm, 0.9 cm or 1 cm. Further, the thickness of the loop pressing yarn portion 21 is equal to the thickness of the loop introduction portion 23. Furthermore, the thickness of the loop pressing yarn portion 21, the thickness of the loop introduction portion 23 and the thickness of the loop pressing yarn sheet mounting portion 22 are all equal. At this time, the loop pressing yarn sheet 20 maintains an overall uniform thickness.

[0103] In a specific example, the first sub-yarn pressing plane 2101 is a smooth plane, the second sub-yarn pressing plane 2103 is a smooth plane, the transition curved surface 2102 is a smooth curved surface, and the loop introduction curved surface 2301 is a smooth curved surface.

[0104] Another embodiment of the present invention provides a yarn pressing device 30 , which includes a loop-forming yarn pressing piece 20 .

[0105] See also Figure 3 In a specific example, the yarn pressing device 30 includes a yarn pressing sheet base 31, a loop pressing sheet 10 and a loop pressing sheet 20, and the loop pressing sheet 10 and the loop pressing sheet 20 are movably connected to the yarn pressing sheet base 31 respectively.

[0106] Further, the tuck yarn pressing piece 10 and the looping yarn pressing piece 20 are arranged in parallel. Optionally, the tuck yarn pressing piece 10 and the looping yarn pressing piece 20 are arranged horizontally. Optionally, the tuck yarn pressing piece 10 and the looping yarn pressing piece 20 are located at the same height.

[0107] Furthermore, the yarn pressing plane 1101 of the tucking yarn pressing portion 11, the first sub-yarn pressing plane 2101 of the looping yarn pressing portion 21 and the second sub-yarn pressing plane 2103 of the looping yarn pressing portion 21 are located in the same plane.

[0108] In a specific example, the yarn pressing device 30 also includes a first sub-base 32, a second sub-base 33, a third sub-base 34 and a fourth sub-base 35. The first sub-base 32 and the second sub-base 33 are movably connected to the yarn pressing sheet base 31, and the first sub-base 32 and the second sub-base 33 can move along the first direction on the yarn pressing sheet base 31 respectively. The third sub-base 34 is movably connected to the first sub-base 32, and the third sub-base 34 can move along the second direction on the first sub-base 32. The fourth sub-base 35 is movably connected to the second sub-base 33, and the fourth sub-base 35 can move along the second direction on the second sub-base 33. The tuck yarn pressing sheet 10 is movably connected to the third sub-base 34, and the tuck yarn pressing sheet 10 can move along the third direction on the third sub-base 34. The looping yarn pressing sheet 20 is movably connected to the fourth sub-base 35, and the looping yarn pressing sheet 20 can move along the third direction on the fourth sub-base 35.

[0109] Further, the first direction, the second direction and the third direction are perpendicular to each other. Optionally, the first direction is the X-axis direction, the second direction is the Y-axis direction, and the third direction is the Z-axis direction.

[0111] Another embodiment of the present invention provides a circular knitting machine, which includes a loop-forming yarn pressing piece 20.

[0112] Another embodiment of the present invention provides a circular knitting machine, which includes a yarn pressing device 30.

[0113] See also Figure 4 and 5 An embodiment of the present invention provides a needle-containing corner block 40 for a circular knitting machine. The needle-containing corner block 40 includes a needle-containing base 41, a first needle-containing stopper 42, and a second needle-containing stopper 43; the first needle-containing stopper 42 and the second needle-containing stopper 43 both protrude from the needle-containing base 41, and there is a gap between the first needle-containing stopper 42 and the second needle-containing stopper 43 to form a knitting needle track 44 for the knitting needle to pass through.

[0114] The first needle-containing position-limiting member 42 has a first needle-containing introduction portion 4201 and a second needle-containing outlet portion 4302, and the second needle-containing position-limiting member 43 has a second needle-containing introduction portion 4301 and a second needle-containing outlet portion 4302; the first needle-containing introduction portion 4201 and the second needle-containing introduction portion 4301 cooperate to form a first needle-containing introduction track, the first needle-containing outlet portion 4202 and the second needle-containing outlet portion 4302 cooperate to form a needle-containing outlet track, the first needle-containing outlet portion 4202 has a first needle-containing outlet plane 42021, the first needle-containing outlet plane 42021 faces the second needle-containing outlet portion 4302, the second needle-containing outlet portion 4302 has a second needle-containing outlet plane 43021, the second needle-containing outlet plane 43021 faces the first needle-containing outlet portion 4202, and the first needle-containing outlet plane 42021 and the second needle-containing outlet plane 43021 are parallel.

[0115] Knitted air layer fabrics are widely favored by consumers for their comfortable feel, fluffy and soft, perspiration-wicking and warm, moisture-absorbing and breathable properties. They are widely used in the preparation of sportswear, casual wear and professional wear. Currently, the most commonly used are "sandwich" type knitted air layer fabrics, such as Fig.16 As shown. Fig.16 In the "sandwich" knitted air layer fabric shown, the yarn count of the middle layer connects the surface layer and the inner layer through a tuck structure to form a "sandwich" type knitted air layer fabric.

[0116] Although the "sandwich" type knitted air layer fabric has a good texture, during use, the yarn count of the middle layer is easy to drill out of the inner layer and the surface layer, resulting in problems such as yarn leakage and pilling, resulting in an uneven surface of the fabric. Based on these defects of the "sandwich" type knitted air layer fabric, the "five-piece" type knitted air layer fabric emerged. Fig.17 The "Five-in-One" type knitted air layer fabric shown in the figure forms a surface layer, a sub-surface layer, a hollow layer, a sub-inner layer and an inner layer in sequence from the surface to the inside. This design can improve the surface performance of the "Sandwich" type knitted air layer fabric to a certain extent. However, it is difficult for traditional knitting equipment to continue to form the surface layer and inner layer of the "Five-in-One" type knitted air layer fabric while maintaining the "Sandwich" needle structure.

[0117] In the needle-containing corner block 40 of the present embodiment, through the cooperation of the first needle-containing stopper 42 and the second needle-containing stopper 43, the first needle-containing introduction part 4201 and the second needle-containing introduction part 4301 cooperate to form a first needle-containing introduction track, the first needle-containing lead-out part 4202 and the second needle-containing lead-out part 4302 cooperate to form a needle-containing lead-out track, the first needle-containing lead-out part 4202 has a first needle-containing lead-out plane 42021, the second needle-containing lead-out part 4302 has a second needle-containing lead-out plane 43021, and the first needle-containing lead-out plane 42021 and the second lead-out plane are parallel. At this time, when the needle-containing corner block 40 is used, the knitting needle can be guided on the lead-out track so that the yarn can neither be de-looped nor looped, so that the surface layer and the inner layer of the "sandwich" type knitted air layer fabric can be formed smoothly on the basis of the "sandwich" needle-containing structure, thereby improving the quality of the fabric.

[0118] In a specific example, the first needle-containing introduction part 4201 has a first needle-containing introduction curved surface 42011, which faces the second needle-containing introduction part 4301, and the second needle-containing introduction part 4301 has a second needle-containing introduction curved surface 43011, which faces the first needle-containing introduction curved surface 43011. In the introduction direction, the distance between the first needle-containing introduction curved surface 42011 and the second needle-containing introduction curved surface 43011 gradually decreases. In this way, the knitting needles can be more smoothly introduced into the needle-containing corner block 40.

[0119] Furthermore, the first needle-containing introduction part 4201 and the second needle-containing introduction part 4301 are in an eight-shape at the position of the introduction port.

[0120] Please refer again Figure 4In a specific needle-containing corner block 40, along the introduction direction, the lead-out end of the needle-containing lead-out track is lower than the lead-in end of the needle-containing lead-in track. Specifically, the needle-containing lead-out track is horizontally arranged. More specifically, along the introduction direction, the slope of the first needle-containing lead-in curved surface 42011 is a negative value. The slope of the first needle-containing lead-out plane 42021 is 0. The slope of the second needle-containing lead-out plane 43021 is 0.

[0121] In a specific example, the first needle-containing lead-out plane 42021 is set horizontally, and the second needle-containing lead-out plane 43021 is set horizontally.

[0122] Please refer again Figure 5 In another specific example, in the needle-containing corner block 40, along the introduction direction, the lead-out end of the needle-containing lead-out track is higher than the lead-in end of the needle-containing lead-in track. Specifically, the needle-containing lead-out track is horizontally arranged. More specifically, the slope of the first needle-containing lead-in curved surface 42011 is a positive value. The slope of the first needle-containing lead-out plane 42021 is 0. The slope of the second needle-containing lead-out plane 43021 is 0.

[0123] In a specific example, the first needle-containing lead-out plane 42021 is set horizontally, and the second needle-containing lead-out plane 43021 is set horizontally.

[0124] In a specific example, the first needle-containing introduction curved surface 42011 and the first needle-containing exporting plane 42021 are smoothly connected, and the second needle-containing introduction curved surface 43011 and the second needle-containing exporting plane 43021 are smoothly connected.

[0125] Please refer again Figure 4 or Figure 5 The first needle-containing position-limiting member 42 also has a first needle-containing transition portion 4203, and the second needle-containing position-limiting member 43 also has a second needle-containing transition portion 4303. The two ends of the first needle-containing transition portion 4203 are respectively connected to the first needle-containing introduction portion 4201 and the first needle-containing outlet portion 4202, and the two ends of the second needle-containing transition portion 4303 are respectively connected to the second needle-containing introduction portion 4301 and the second needle-containing outlet portion 4302.

[0126] Specifically, the first needle-containing transition portion 4203 has a first needle-containing transition surface 42031, which faces the second needle-containing transition portion 4303, and the second needle-containing transition portion 4303 has a second needle-containing transition surface 43031, which faces the first needle-containing transition portion 4203; the two ends of the first needle-containing transition surface 42031 are smoothly connected to the first needle-containing introduction surface 42011 and the first needle-containing export plane 42021, respectively, and the two ends of the second needle-containing transition surface 43031 are smoothly connected to the second needle-containing introduction surface 43011 and the second needle-containing export plane 43021, respectively.

[0127] More specifically, the first needle-containing transition curved surface 42031 is parallel to the second needle-containing transition curved surface 43031. This can effectively improve the stability of the knitting needles moving in the track.

[0128] In a specific example, the needle-containing corner block 40 further includes a mounting hole 45, which penetrates the corner block for mounting the needle-containing corner block 40. Optionally, the mounting hole 45 is staggered with the knitting needle track 44. Further, the mounting hole 45 is provided on the second limiting member.

[0129] Another embodiment of the present invention provides a circular knitting machine corner seat, which includes the needle-containing corner block 40.

[0130] Another embodiment of the present invention provides an edge group for a circular knitting machine, which includes the needle-containing edge block 40 .

[0131] Another embodiment of the present invention provides a circular knitting machine, which includes the needle-containing corner block 40 .

[0132] Referring to Figure 6, another embodiment of the present invention provides a circular knitting machine needle-out angle block 50. The needle-out angle block 50 includes a needle-out base 51, a first needle-out stopper 52, and a second needle-out stopper 53; the first needle-out stopper 52 and the second needle-out stopper 53 both protrude from the needle-out base 51, and there is a gap between the first needle-out stopper 52 and the second needle-out stopper 53 to form a knitting needle track 54 for the knitting needle to pass through.

[0133] The first needle-exit stopper 52 has a first needle-exit introduction portion 5201, a first needle-exit lifting portion 5202, a first needle-exit flat portion 5203, a first needle-exit re-raising portion 5204, and a first needle-exit descending portion 5205, which are arranged in sequence. The second needle-exit stopper 53 has a second needle-exit introduction portion 5301, a second needle-exit lifting portion 5302, a second needle-exit flat portion 5303, a second needle-exit re-raising portion 5304, and a second needle-exit descending portion 5305, which are arranged in sequence.

[0134] The first needle outlet introduction portion 5201 and the second needle outlet introduction portion 5301 cooperate to form a needle outlet introduction track, the first needle outlet lifting portion 5202 and the second needle outlet lifting portion 5302 cooperate to form a needle outlet lifting track, the first needle outlet flat portion 5203 and the second needle outlet flat portion 5303 cooperate to form a needle outlet flat track, the first needle outlet re-raising portion 5204 and the second needle outlet re-raising portion 5304 cooperate to form a needle outlet re-raising track, and the first needle outlet descending portion 5205 and the second needle outlet descending portion 5305 cooperate to form a needle outlet guide track.

[0135] When processing the "five-piece" type knitted air fabric, the surface of the fabric obtained by traditional knitting equipment is prone to problems such as needle marks and thread leakage, which will greatly reduce the surface quality of the fabric. In the needle outlet angle block 50 of this embodiment, through the cooperation of the first needle outlet stopper 52 and the second needle outlet stopper 53, a needle outlet introduction track, a needle outlet lifting track, a needle outlet gentle track, a needle outlet re-lifting track and a needle outlet track are formed in sequence along the movement direction of the knitting needle. By designing the structure of the needle outlet angle block 50, a plurality of tracks of different heights are formed on the needle outlet angle block 50, so that during the knitting process, in the needle outlet stage, through the cooperation of each track, the adjustment of the needle outlet track of the knitting needle can effectively improve the yarn tension, effectively reduce the risk of needle marks, thread leakage and other problems on the surface of the fabric, and improve the surface quality of the fabric.

[0136] In a specific example, the first needle outlet introduction portion 5201 has a first needle outlet introduction curved surface, which faces the second needle outlet introduction portion 5301; the first needle outlet lifting portion 5202 has a first needle outlet lifting curved surface, which faces the second needle outlet lifting portion 5302; the first needle outlet flat portion 5203 has a first needle outlet flat plane, which faces the second needle outlet flat portion 5303; the first needle outlet re-raising portion 5204 has a first needle outlet re-raising curved surface, which faces the second needle outlet re-raising portion 5304; the first needle outlet descending portion 5205 has a first needle outlet descending curved surface, which faces the second needle outlet descending portion 5305. The second needle introduction part 5301 has a second needle introduction curved surface, which faces the first needle introduction part 5201; the second needle lifting part 5302 has a second needle lifting curved surface, which faces the first needle lifting part 5202; the second needle flat part 5303 has a second needle flat plane, which faces the first needle flat part 5203; the second needle re-raising part 5304 has a second needle re-raising curved surface, which faces the first needle re-raising part 5204; the second needle descending part 5305 has a second needle descending curved surface, which faces the first needle descending part 5205. Through the design of curved surfaces and planes, a knitting needle track 54 that is more suitable for knitting needles to be needled is obtained, so that the knitting needles can move stably and smoothly in the track, which is conducive to improving the stability of needles and further improving the surface quality of fabrics.

[0137] Furthermore, along the introduction direction, the distance between the first needle-outlet introduction curved surface and the second needle-outlet introduction curved surface gradually decreases, so that the knitting needles can be introduced into the needle-outlet corner block 50 more smoothly.

[0138] Furthermore, the first needle introduction portion 5201 and the second needle introduction portion 5301 are in an eight-shape at the position of the introduction port.

[0139] In a specific example, the first needle lifting curved surface is parallel to the second needle lifting curved surface, the first needle flat plane is parallel to the second needle flat plane, the first needle re-raising curved surface is parallel to the second needle re-raising curved surface, and the first needle descending curved surface is parallel to the second needle descending curved surface. In this case, the corresponding surfaces can be kept at a uniform distance, and the knitting needle can be more stably confined in the knitting needle track 54.

[0140] Furthermore, the first needle introduction curved surface, the first needle lifting curved surface, the first needle outlet flat plane, the first needle outlet re-raising curved surface and the first needle outlet descending curved surface are smoothly connected in sequence; the second needle introduction curved surface, the second needle outlet lifting curved surface, the second needle outlet flat plane, the second needle outlet re-raising curved surface and the second needle outlet descending curved surface are smoothly connected in sequence.

[0141] In a specific example, the leading end of the first needle exit descending curved surface is flush with the first needle exit flat plane, and the leading end of the second needle exit descending curved surface is flush with the second needle exit flat plane. At this time, the leading end of the needle exit guide track is at the same height as the flat track, which can make the knitting needle more stably lead out of the needle exit corner block 50. At the same time, making the leading height of the knitting needle at the same height as the flat track avoids additional knitting of the yarn in the needle exit corner block 50, which can further improve the surface quality of the fabric.

[0142] In a specific example, the height difference between the beginning and the end of the first needle-outlet re-rising curved surface is 4.5 cm to 5.5 cm. Optionally, the height difference between the beginning and the end of the first needle-outlet re-rising curved surface is 4.5 cm, 4.6 cm, 4.7 cm, 4.8 cm, 4.9 cm, 5.0 cm, 5.1 cm, 5.2 cm, 5.3 cm, 5.4 cm or 5.5 cm.

[0143] It is understandable that the height difference between the beginning and the end of the second needle-outlet re-rising curved surface is 4.5 cm to 5.5 cm. Optionally, the height difference between the beginning and the end of the second needle-outlet re-rising curved surface is 4.5 cm, 4.6 cm, 4.7 cm, 4.8 cm, 4.9 cm, 5.0 cm, 5.1 cm, 5.2 cm, 5.3 cm, 5.4 cm or 5.5 cm.

[0144] In a specific example, the needle-out corner block 50 further includes a mounting hole 55, which penetrates the corner block for mounting the needle-out corner block 50. Optionally, the mounting hole 55 is staggered with the knitting needle track 54. Further, the mounting hole 55 is provided on the second stopper.

[0145] Another embodiment of the present invention provides a circular knitting machine corner seat, which includes the needle outlet corner block 50 described above.

[0146] Another embodiment of the present invention provides an edge group for a circular knitting machine, which includes the needle outlet edge block 50 described above.

[0147] Another embodiment of the present invention provides a circular knitting machine, which includes the needle outlet corner block 50 described above.

[0148] See also Figure 7 In another embodiment of the present invention, there is provided a flat needle corner block 60 on an upper plate of a circular knitting machine. The flat needle corner block 60 on the upper plate comprises a flat needle base 61, a first flat needle stopper 62 and a second flat needle stopper 63; the first flat needle stopper 62 and the second flat needle stopper 63 both protrude from the flat needle base 61, and there is a gap between the first flat needle stopper 62 and the second flat needle stopper 63 to form a knitting needle track for the knitting needle to pass through. The two ends of the first flat needle stopper 62 respectively form a first flat needle introduction part 6201 and a first flat needle outlet part 6202, and the two ends of the second flat needle stopper 63 respectively form a second flat needle introduction part 6301 and a second flat needle outlet part 6302; the first flat needle introduction part 6201 and the second flat needle introduction part 6301 cooperate to form a flat needle introduction track, and the first flat needle outlet part 6202 and the second flat needle outlet part 6302 cooperate to form a flat needle outlet track 64. In the needle exit direction, the lead-out end of the flat needle lead-out track 64 is located in front of the lead-in end of the flat needle lead-in track.

[0149] Plain stitch is a common knitting stage in the textile process. In the plain stitch stage, the knitting needle mainly hooks the yarn and maintains the shape of the yarn to promote the smooth progress of knitting. At present, although plain stitch knitting is relatively mature and can basically meet the requirements of the textile process for plain stitch. However, in the traditional plain stitch process, due to the structural design constraints of the knitting needle corner block, the stability of the yarn shape is poor, and the problem of loose coils is prone to occur, which in turn leads to reduced fabric quality.

[0150] In the upper plate flat needle corner block 60 of the present embodiment, the structure of the corner block is designed so that the first flat needle stopper 62 and the second flat needle stopper 63 cooperate with each other to guide the movement trajectory of the knitting needle, so that the knitting needle moves stably and effectively maintains the shape of the yarn. Specifically, the two ends of the first flat needle stopper 62 respectively form the first flat needle introduction part 6201 and the first flat needle outlet part 6202, and the two ends of the second flat needle stopper 63 respectively form the second flat needle introduction part 6301 and the second flat needle outlet part 6302; the first flat needle introduction part 6201 and the second flat needle introduction part 6301 cooperate to form a flat needle introduction track, and the first flat needle outlet part 6202 and the second flat needle outlet part 6302 cooperate to form a flat needle outlet track 64. The knitting needle moves stably in the introduction track and the outlet track to maintain the shape of the yarn. In addition, along the needle outlet direction, the outlet end of the flat needle outlet track 64 is located in front of the introduction end of the flat needle introduction track. By setting the lead-out end of the flat needle lead-out track 64 in front of the lead-in end of the flat needle lead-in track, the shape of the yarn can be further maintained, especially the stable shape of the yarn loop arc, effectively avoiding the problem of loose coils and improving the quality of the fabric.

[0151] Furthermore, in the upper plate flat needle corner block 60 of the present embodiment, the upper plate flat needle corners are integrated into a whole corner block, which can further maintain the smoothness of the knitting needle operation, further improve the stability of the yarn shape, and thus improve the quality of the fabric.

[0152] In a specific example, the first flat needle introduction portion 6201 has a first flat needle introduction curved surface, which faces the second flat needle introduction portion 6301; the first flat needle outlet portion 6202 has a first flat needle outlet curved surface, which faces the second flat needle outlet portion 6302; the second flat needle introduction portion 6301 has a second flat needle introduction curved surface, which faces the first flat needle introduction portion 6201; the second flat needle outlet portion 6302 has a second flat needle outlet curved surface, which faces the first flat needle outlet portion 6202; the first flat needle outlet curved surface is parallel to the second flat needle outlet curved surface.

[0153] Furthermore, the first flat needle lead-out curved surface is a circular arc surface, and the second flat needle lead-out curved surface is a circular arc surface. In this case, the movement of the knitting needle can be made smoother, and the knitting effect can be further improved.

[0154] In a specific example, a side of the first flat needle stopper 62 away from the knitting needle track has a clearance groove 6203, and the clearance groove 6203 is used to install a yarn pressing piece. By setting the clearance groove 6203, a yarn pressing piece can be installed in the clearance groove 6203, thereby limiting the position of the yarn during the knitting process to a certain extent, reducing the risk of defects such as coil floating during the knitting process.

[0155] Please refer again Figure 7 In a specific example, the clearance groove 6203 is located outside the needle track. Figure 7 In the corner block shown, the clearance groove 6203 is located on the first flat needle limiting member 62.

[0156] In a specific example, along the introduction direction, the distance between the first flat needle introduction curved surface and the second flat needle introduction curved surface gradually decreases.

[0157] Furthermore, the first flat needle introduction part 6201 and the second flat needle introduction part 6301 are in an eight-shape at the position of the introduction port.

[0158] Furthermore, the first flat needle introduction curved surface is smoothly connected to the first flat needle outlet curved surface; the second flat needle introduction curved surface is smoothly connected to the second flat needle outlet curved surface.

[0159] In a specific example, the upper plate flat needle corner block 60 further includes a mounting hole 65, which penetrates the corner block for mounting the upper plate flat needle corner block 60. Optionally, the mounting hole 65 is staggered with the needle track. Further, the mounting hole 65 is provided on the first stopper. Furthermore, there are multiple mounting holes 65, and the multiple mounting holes 65 are distributed on the first stopper for stably mounting the upper plate flat needle corner block 60. Figure 7 In the upper plate flat needle corner block 60 shown, there are two mounting holes 65, and the two mounting holes 65 are respectively located at two ends of the first limiting member.

[0160] Another embodiment of the present invention provides a circular knitting machine corner seat, which includes the upper plate flat needle corner block 60.

[0161] Another embodiment of the present invention provides an edge group for a circular knitting machine, which includes the upper plate flat needle edge block 60 .

[0162] Another embodiment of the present invention provides a circular knitting machine, which includes the upper plate flat needle corner block 60 .

[0163] See also Figure 8 In another embodiment of the present invention, there is provided an edge group 70 of a circular knitting machine. The edge group 70 of the circular knitting machine comprises an upper edge seat 71 and a lower edge seat 72. The upper edge seat 71 and the lower edge seat 72 cooperate to introduce the upper knitting needles and the lower knitting needles respectively; the knitting needle introduction end of the upper edge seat 71 is flush with the knitting needle introduction end of the lower edge seat 72.

[0166] The width of the first upper plate needle-containing corner block 7101 is equal to the width of the first lower plate needle-containing corner block 7201; the width of the second upper plate needle-containing corner block 7102 is equal to the width of the second lower plate needle-containing corner block 7202; the sum of the widths of the first upper plate needle-exiting corner block 7103 and the third upper plate needle-containing corner block 7104 is equal to the width of the first lower plate flat needle corner block 7203; the sum of the widths of the second upper plate needle-exiting corner block 7105 and the fourth upper plate needle-containing corner block 7106 is equal to the width of the second lower plate flat needle corner block 7204; the sum of the widths of the lower plate needle-exiting corner block 7205, the third lower plate needle-containing corner block 7206, the fourth lower plate needle-containing corner block 7207 and the fifth lower plate needle-containing corner block 7208 is equal to the width of the upper plate flat needle corner block 7107.

[0167] In the circular knitting machine corner group 70 in this embodiment, the upper plate corner seat 71 and the lower plate corner seat 72 are set, so that the circular knitting machine corner group 70 is more suitable for knitting "five-piece" type air knitted fabrics. Specifically, by setting the upper plate corner seat 71 and the lower plate corner seat 72 respectively, the needle-containing corner blocks, the needle-out corner blocks and the flat needle corner blocks are reasonably arranged, and the corner blocks of the upper plate corner seat 71 correspond to the corner blocks of the lower plate corner seat 72. When the circular knitting machine corner group 70 is used to knit "five-piece" type air knitted fabrics, a stable "five-piece" structure can be formed, thereby improving the quality of the "five-piece" type air knitted fabrics.

[0168] Specifically, the first upper needle-containing corner block 7101 includes a first needle-containing base, a first needle-containing limiter and a second needle-containing limiter; the first needle-containing limiter and the second needle-containing limiter both protrude from the first needle-containing base, and there is a gap between the first needle-containing limiter and the second needle-containing limiter to form a knitting needle track for the knitting needle to pass through. The first needle-containing position-limiting member has a first needle-containing introduction portion and a first needle-containing outlet portion, and the second needle-containing position-limiting member has a second needle-containing introduction portion and a second needle-containing outlet portion; the first needle-containing introduction portion and the second needle-containing introduction portion cooperate to form a first needle-containing introduction track, and the first needle-containing outlet portion and the second needle-containing outlet portion cooperate to form a needle-containing outlet track, the first needle-containing outlet portion has a first needle-containing outlet plane, the first needle-containing outlet plane faces the second needle-containing outlet portion, the second needle-containing outlet portion has a second needle-containing outlet plane, the second needle-containing outlet plane faces the first needle-containing outlet portion, and the first needle-containing outlet plane and the second needle-containing outlet plane are parallel; along the introduction direction, the outlet end of the outlet track of the first upper plate needle-containing corner block 7101 is lower than the introduction end of the first needle-containing introduction track.

[0169] By designing the structure of the first upper needle-containing corner block 7101, it is possible to smoothly form the surface and inner layers of the "sandwich" type knitted air layer fabric on the basis of the "sandwich" needle-containing structure, thereby further improving the quality of the fabric.

[0170] It can be understood that the shape of the knitting needle track of the first upper plate containing needle corner block 7101 is similar to Figure 5 The shape of the corresponding knitting needle track containing the needle corner block is mirror-symmetrical.

[0171] Furthermore, the second upper plate needle-containing corner block 7102 includes a second needle-containing base, a third needle-containing limiter and a fourth needle-containing limiter; the third needle-containing limiter and the fourth needle-containing limiter both protrude from the second needle-containing base, and there is a gap between the third needle-containing limiter and the fourth needle-containing limiter to form a knitting needle track for the knitting needle to pass through. The third needle-containing position-limiting member has a third needle-containing introduction portion and a third needle-containing outlet portion, and the fourth needle-containing position-limiting member has a fourth needle-containing introduction portion and a fourth needle-containing outlet portion; the third needle-containing introduction portion and the fourth needle-containing introduction portion cooperate to form a second needle-containing introduction track, the third needle-containing outlet portion and the fourth needle-containing outlet portion cooperate to form a needle-containing outlet track, the third needle-containing outlet portion has a third needle-containing outlet plane, the third needle-containing outlet plane faces the fourth needle-containing outlet portion, the fourth needle-containing outlet portion has a fourth needle-containing outlet plane, the fourth needle-containing outlet plane faces the third needle-containing outlet portion, and the third needle-containing outlet plane is parallel to the fourth needle-containing outlet plane; along the introduction direction, the outlet end of the outlet track of the second upper plate needle-containing corner block 7102 is higher than the introduction end of the second needle-containing introduction track.

[0172] It can be understood that the shape of the knitting needle track of the second upper plate containing needle corner block 7102 is similar to Figure 4The shape of the corresponding knitting needle track containing the needle corner block is mirror-symmetrical.

[0175] It is understandable that the first lower plate needle-containing corner block 7201 can be Figure 5 The second lower plate needle-containing corner block 7202 may be Figure 4 The needle-shaped corner block shown.

[0176] In a specific example, the first upper plate needle-out angle block 7103 includes a needle-out base, a first needle-out stopper and a second needle-out stopper; the first needle-out stopper and the second needle-out stopper both protrude from the needle-out base, and there is a gap between the first needle-out stopper and the second needle-out stopper to form a knitting needle track for the knitting needle to pass through. The first needle-out stopper has a first needle-out introduction portion, a first needle-out lifting portion, a first needle-out flat portion, a first needle-out re-raising portion and a first needle-out descending portion arranged in sequence. The second needle-out stopper has a second needle-out introduction portion, a second needle-out lifting portion, a second needle-out flat portion, a second needle-out re-raising portion and a second needle-out descending portion arranged in sequence.

[0178] By designing the structure of the first upper disk needle outlet angle block 7103, a plurality of tracks of different heights are formed on the first upper disk needle outlet angle block 7103. In this way, during the knitting process, at the needle outlet stage, through the coordination of various tracks, the adjustment of the needle outlet trajectory can effectively improve the yarn tension, effectively reduce the risks of needle marks, thread leakage and other problems on the fabric surface, and improve the surface quality of the fabric.

[0179] Furthermore, the shape of the needle track of the second upper disk needle outlet angle block 7105 is the same as the shape of the needle track of the first upper disk needle outlet angle block 7103, and the shape of the needle track of the lower disk needle outlet angle block 7205 is mirror-symmetrical to the shape of the needle track of the first upper disk needle outlet angle block 7103.

[0180] It is understandable that the lower plate needle corner block 7205 can be Figure 6 The needle exit corner block shown.

In the needle outlet direction, the outlet end of the flat needle outlet track is located in front of the introduction end of the flat needle introduction track.

[0182] By designing the structure of the upper flat needle corner block 7107, the outlet end of the flat needle outlet track is arranged in front of the inlet end of the flat needle inlet track, so as to further maintain the shape of the yarn, especially maintain the stable shape of the yarn loop arc, effectively avoid the problem of loose coils, and improve the quality of the fabric. Furthermore, in the upper flat needle corner block 7107 of this embodiment, the upper flat needle corners are integrated into a whole corner block, which can further maintain the smoothness of the knitting needle operation, further improve the stability of the yarn shape, and thus improve the quality of the fabric.

[0183] It is understandable that the upper plate flat needle corner block 7107 can be Figure 7 The upper plate flat needle edge block 7107 is shown.

[0184] In a specific example, the first lower plate flat needle corner block 7203 has a knitting needle track, which is divided into an introduction section and a smooth section; along the introduction direction, the opening of the introduction section gradually decreases, and the opening size of the smooth section remains unchanged. Optionally, the smooth section is arranged horizontally.

[0185] Furthermore, the shape of the knitting needle track of the second lower plate flat needle corner block is the same as the shape of the knitting needle track of the first lower plate flat needle corner block 7203.
