Description

Technical Field

[0001] The invention relates to the field of textile equipment, in particular to a weft knitting exchange yarn adding jacquard machine. Background Art

[0002] Weft-knitted plated fabrics are a type of fabric produced on a single-sided circular knitting machine. They are characterized by having all or some of the loops formed by two yarns, with the loops formed by the two yarns positioned on the front and back of the fabric as required. These fabrics can be categorized as fully plated or partially plated. This patent relates to weft-knitted fully plated fabrics.

[0003] Currently, weft-knitted added yarn fabrics are primarily produced on four-needle, single-jersey circular knitting machines. These fabrics are generally solid-colored, with pattern formation primarily achieved through post-processing, such as printing, embossing, and burn-out. These processes require printing, embossing, and burn-out, requiring significant equipment and processes, increasing production costs and environmental pollution. Computerized jacquard single-jersey circular knitting machines primarily produce structural jacquard fabrics. However, when producing colored jacquard fabrics, the size of the pattern is limited due to the length of the floating threads.

[0004] Chinese patent application No. 201410785334.4 discloses a weft-knitted single-sided exchange-padded jacquard fabric. This fabric utilizes a single-sided plain weft stitch as its basic weave. A single-sided circular knitting machine with four needle tracks is equipped with an exchange-padded yarn feeding device for each loop forming system. The left and right yarn guide fingers of the exchange-padded yarn feeding device, respectively, feed colored yarns A and B into the loop forming system simultaneously. Under the control of a control system, the exchange-padded yarns are exchanged and combined with pattern information to form the jacquard fabric. This single-sided jacquard fabric is produced on a single-sided circular knitting machine equipped with a four-needle track exchange-padded yarn feeding device and control system. The pattern is formed by alternating two colored yarns on the front of the fabric. This jacquard fabric has no restrictions on pattern size and a uniform and stable weave structure.

[0005] The above patent discloses that an exchangeable yarn feeding device is used to realize the exchange of color A yarn and color B yarn. Specifically, color A yarn and color B yarn are respectively passed through the corresponding yarn guide holes of the two yarn guide fingers; when one air valve is opened, the yarn guide finger at the corresponding position is pushed to move radially toward the inside of the needle cylinder, so that the reset spring is tensioned, the yarn guide finger approaches the knitting needle, and the color A yarn in the corresponding yarn guide hole is padded into the knitting needle to form the face yarn. At this time, the other air valve is closed, the yarn guide finger at the corresponding position is away from the knitting needle, and the color B yarn passed through the corresponding yarn guide hole is padded into the needle. The knitting needles form the ground yarn; when one air valve is closed, the return spring returns to the corresponding position to move the yarn guide finger radially toward the outside of the needle cylinder, so that the corresponding yarn guide hole is away from the knitting needle, and the A-colored yarn in the corresponding yarn guide hole is padded into the knitting needle to form the ground yarn. At this time, the other air valve is opened, and the B-colored yarn is padded into the knitting needle to form the surface yarn; however, when the A-colored yarn and the B-colored yarn are bent into loops and the coils are kept stable by the sinker, the coils formed by the A-colored yarn and the B-colored yarn are shifted, causing the woven fabric to become loose and the quality of the fabric product to decline.

[0036] A winding device, the winding device being arranged at the output end of the weaving device;

[0037] The yarn feeding device, yarn feeding device, weaving device and winding device are electrically connected to the control system respectively;

[0038] The knitting device includes a needle cylinder 1, a sinker ring 2, a knitting needle 3, a cam seat 4, a cam 5, a sinker 6, an auxiliary sinker 7, a sinker cam seat 8, a sinker cam 9, a connecting needle 10, a jacquard piece 11 and a needle selector 12. The sinker ring 2 is arranged on the upper side of the needle cylinder 1, and the sinker ring 2 has an upper needle groove 21. The sinker 6 and the auxiliary sinker 7 are arranged in the same upper needle groove 21. The sinker cam seat 8 is arranged on the upper side of the sinker ring 2. The sinker cam 9 is arranged on the lower surface of the sinker cam seat 8. The sinker cam 9 has a needle butt for the sinker 6 and the auxiliary sinker 7 to slide. The sinker track 91 and the auxiliary sinker track 92 are provided on the outer surface of the needle cylinder 1 with a lower needle groove 11. The knitting needle 3, the connecting needle 10 and the jacquard piece 11 are arranged in the same lower needle groove 11. The connecting needle 10 is provided on the lower side of the knitting needle 3 and is movably connected to the knitting needle 3. The jacquard piece 11 is provided on the lower side of the connecting needle 10 and is connected to the connecting needle 10. The needle selector 12 is provided on the outer side of the jacquard piece 11 and is in contact with the jacquard piece 11. The cam seat 4 is provided on the outer side of the circumference of the needle cylinder 1. The cam 5 is provided on the cam seat 4. The cam 5 has a knitting needle track 51 and a connecting needle track 52 for sliding the butts of the knitting needle 3 and the connecting needle 10.

[0039] The weft knitting exchange and adding yarn jacquard machine uses a yarn feeding device to evenly feed the A color yarn and the B color yarn respectively, so that the feeding of the A color yarn and the B color yarn is stable, and then the A color yarn and the B color yarn are continuously fed through the yarn feeding device while keeping the tension of the A color yarn and the B color yarn stable, and the yarn feeding device alternately changes the inlay yarn horizontal angle of the A color yarn and the B color yarn, and then the A color yarn and the B color yarn are input into the weaving device for weaving. That is, when the adding yarn jacquard needs to be exchanged, the yarn feeding device is controlled to change the inlay yarn horizontal angle of the A color yarn and the B color yarn according to the designed pattern, so that the A color yarn forms the surface yarn and the B color yarn forms the bottom yarn, or the A color yarn forms the bottom yarn. The A-colored yarn forms the bottom yarn, and the B-colored yarn forms the surface yarn. Thus, the alternating colors of the floating lines formed in the weaving of the A-colored yarn and the B-colored yarn on the same surface form a corresponding jacquard pattern. Specifically, in the weaving process, the alternating A-colored yarn and B-colored yarn are hooked by the knitting needle 3 and then narrowed. At the same time, the sinker 6 and the auxiliary sinker 7 narrow the needle, so that the A-colored yarn and the B-colored yarn are bent into loops, and then the sinker 6 and the auxiliary sinker 7 are used to remove the needle to maintain the loops formed by the bent yarns of the A-colored yarn and the B-colored yarn, and they can be maintained in the corresponding looping position, so that the woven fabric is not easy to fall apart, thereby ensuring the quality of the fabric product.

[0040] It is worth noting that the tension of the color yarn A input into the weaving device is greater than the tension of the color yarn B. When bending the yarn, the color yarn B is on the inside of the hook of the knitting needle 3. When forming a loop, the color yarn A is close to the inside of the hook of the knitting needle 3.

[0041] Specifically, refer to Figure 3 and Figure 4 As shown, the sinker 6 includes a first plate 61, a first butt 62 provided at the rear end of the first plate 61, and a first butt 63 provided in the middle of the first plate 61. A first groove 64 and a second groove 65 are sequentially provided on the front side edge of the first butt 63 along the longitudinal direction, so that the first butt 63 forms a first protrusion 66 and a second protrusion 67. The width of the first protrusion 66 is smaller than the width of the second protrusion 67. An arc structure 68 is provided on the outer edge of the second protrusion 67. The auxiliary sinker 7 includes a second plate 71, a second butt 72 provided at the rear end of the second plate 71, and a second butt 73 provided in the middle of the second plate 71. A third groove 74 is provided on the front side edge of the second butt 73, so that the second butt 73 forms a third protrusion 75. When the sinker 6 and the auxiliary sinker 7 overlap, the third protrusion 75 covers the first groove 64. The length of the first plate 61 is smaller than the length of the second plate 71.

[0042] So, reference Figure 2As shown, during the loop forming process, the knitting needle 3 narrows down after hooking the yarn, and the sinker 6 and the auxiliary sinker 7 narrow down together, and the narrowing speed of the sinker 6 is greater than the narrowing speed of the auxiliary sinker 7, so that the old loop formed by weaving the A-colored yarn and the B-colored yarn passes through the first groove 64 and is pressed on the upper edge of the second projection 67 by the third protrusion 75 of the auxiliary sinker 7 and passes through the third groove 75. When the auxiliary sinker 7 is distanced from the sinker 6, the A-colored yarn and the B-colored yarn are flipped, so that the loop formation of the A-colored yarn and the B-colored yarn is stable, thereby improving the quality of the product.

[0043] In this embodiment, reference Figure 5 and Figure 6 As shown, the yarn feeding device includes a housing 101, a driving motor 102, a rotating shaft 103, a first yarn guide wheel 104, a second yarn guide wheel 105, two yarn feeding assemblies 106, two yarn outlet assemblies 107, two tensioning force adjustment assemblies 108 and a yarn pad horizontal angle adjustment assembly 109, the driving motor 102 is fixed on the housing 101, the rotating shaft 103 is rotatably arranged on the housing 101 along the vertical direction and is connected to the driving motor 102, the first yarn guide wheel 104 and the second yarn guide wheel 105 are sequentially arranged on the rotating shaft 103 along the vertical direction, the two yarn feeding assemblies 106 are respectively arranged on the yarn inlet side of the first yarn guide wheel 104 and the second yarn guide wheel 105, The yarn assembly 106 has a yarn inlet porcelain eye 1061, and the two tension adjustment assemblies 108 are provided on the housing 101 and are respectively distributed on the circumferential sides of the first yarn guide wheel 104 and the second yarn guide wheel 105. The tension adjustment assembly 108 has a movable yarn guide frame 1081, and the free end of the movable yarn guide frame 1081 has a yarn guide porcelain eye 1082. The tension adjustment assembly 108 is connected to the yarn inlet assembly 106 so that the yarn guide porcelain eye 1082 moves synchronously with the yarn inlet porcelain eye 1061. The two yarn outlet assemblies 107 are respectively provided on the yarn outlet sides of the first yarn guide wheel 104 and the second yarn guide wheel 105. The yarn pad horizontal angle adjustment assembly 109 is provided at the output end of the yarn outlet assembly 107;

[0044] Colored yarn A and colored yarn B enter through the yarn-feeding porcelain eyes 1061 on the two yarn-feeding components 106 respectively, and are wound around the first yarn guide wheel 104 and the second yarn guide wheel 105 respectively. The driving motor 102 synchronously drives the first yarn guide wheel 104 and the second yarn guide wheel 105 to move, thereby driving the synchronous delivery of colored yarn A and colored yarn B, and then bypasses the yarn-feeding porcelain eyes 1082 on the tensioning force adjusting component 108, and is introduced into the yarn padding horizontal angle adjusting component 109 through the yarn-discharging component 107. The yarn padding horizontal angle adjusting component 109 adjusts the yarn padding horizontal angle of colored yarn A and colored yarn B. Angle, such alternating and repeated adjustments may easily cause changes in the conveying tension of color yarn A and color yarn B. The tension adjustment component 108 is connected to the yarn feeding component 106, so that the yarn guide porcelain eye 1082 and the yarn feeding porcelain eye 1061 move synchronously, so that the storage yarn amount wound on the first yarn guide wheel 104 and the second yarn guide wheel 105 changes, and the swing angle of color yarn A and color yarn B and the distance from the first yarn guide wheel and the second yarn guide wheel all change, so that the tension of color yarn A and color yarn B can be maintained when adjusting the horizontal angle of the pad yarn, thereby ensuring the weaving quality.

[0045] The yarn feeding assembly 106 includes a yarn feeding swing frame 1062, a yarn feeding plate 1063 provided at the outer end of the yarn feeding swing frame 1062, and the yarn feeding porcelain eye 1061 is provided on the yarn feeding plate 1063;

[0046] The yarn discharging assembly 107 includes a yarn discharging plate 1072 fixed on the housing 101 and a yarn discharging porcelain eye 1071 provided on the yarn discharging plate 1072;

[0047] The tensioning force adjustment assembly 108 includes a rotating shaft 1083 rotatably provided on the housing 101, a plate 1084 is fixedly provided on the rotating shaft 1083, and the plate 1084 has a first extension portion and a second extension portion protruding outwardly in the radial direction of the rotating shaft 1083, a torsion spring 1085 is provided between the rotating shaft 1083 and the housing 101, an end of the movable yarn guide frame 1081 away from the yarn guide porcelain eye 1082 is fixedly connected to the first extension portion, and an end of the yarn feed swing frame 1081 away from the yarn feed porcelain eye 1061 is fixedly connected to the second extension portion, so that the yarn feed swing frame 1062 and the movable yarn guide frame 1081 both swing synchronously along the rotating shaft;

[0048] The central axis of the rotating shaft 1083 is parallel to the central axis of the rotating shaft 103 and does not overlap;

[0049] The movable yarn guide frame 1081 is in an "L"-shaped structure, so that the yarn guide eye 1082 moves in an arc when the movable yarn guide frame 1081 swings;

[0050] When the yarn padding horizontal angle adjustment component acts on the A-colored yarn and the B-colored yarn, the tension of the A-colored yarn and the B-colored yarn changes, thereby acting on the movable yarn guide frame 1081 to swing, so that the yarn guide porcelain eye 1082 on the movable yarn guide frame 1081 moves closer to or away from the first yarn guide wheel 104 and the second yarn guide wheel 105 along the arc, and drives the yarn feed porcelain eye 1061 on the yarn feed swing frame 1062 to swing through the rotating shaft 1083, thereby realizing synchronous adjustment of the yarn feed and yarn guide angles, thereby improving the adjustment accuracy and adjustment range, and achieving a good tension adjustment effect of the A-colored yarn and the B-colored yarn.

[0051] The inlay yarn horizontal angle adjustment component 109 includes two guide grooves 201 arranged side by side on the shell 101 along the longitudinal direction, and a slide 202 is slidably provided in the two guide grooves 201. A second yarn guide porcelain eye 203 is provided in the middle of each slide 202, and a magnet 204 is provided on the upper and lower surfaces of each slide 202. An electromagnet 205 is provided at the upper and lower ends of each guide groove 201, and each electromagnet 205 is electrically connected to the control system.

[0052] By controlling the electromagnets 205 at the upper and lower ends of the guide groove 201 to be energized, the electromagnets 205 cooperate with the magnets 204 to achieve the sliding of the slide 202, thereby adjusting the horizontal angle of the yarn pad. This structure has a fast response speed and can quickly ensure the angular accuracy of the horizontal angle of the yarn pad.

[0053] The first yarn guide wheel 104 and the second yarn guide wheel 105 can move in the axial direction of the rotating shaft. Specifically, the outer surface of the rotating shaft 103 is provided with a convex strip 114 in the axial direction, and the inner surfaces of the first yarn guide wheel 104 and the second yarn guide wheel 105 are provided with a groove 115 that cooperates with the convex strip 114. The cooperation between the convex strip 114 and the groove 115 is a prior art, and no further details are given here. A first spring 111 is provided between the upper surface of the first yarn guide wheel 104 and the housing 101, and a second spring 111 is provided between the lower surface of the first yarn guide wheel 104 and the upper surface of the second yarn guide wheel 105. 2. A third spring 113 is provided between the lower surface of the second yarn guide wheel 105 and the housing 101. Through the arrangement of the first spring 111, the second spring 112 and the third spring 113, the first yarn guide wheel 104 and the second yarn guide wheel 105 achieve dynamic balance. When the tension of the color yarn A and the color yarn B changes, the first yarn guide wheel 104 and the second yarn guide wheel 105 can be driven to move synchronously along the axial direction of the rotating shaft, and then the color yarn A and the color yarn B are synchronously adjusted, so that the color yarn A and the color yarn B are linked during the conveying process, thereby improving the efficiency of the tension adjustment and ensuring the quality of the product.
