Description

Technical Field

[0001] This invention patent relates to the technical field of knitting, and particularly to an arbitrary loop sinker device for knitting machines. Background Art

[0002] An arbitrary loop sinker device refers to a device that can realize knitting loop structures at any part and any position of a fabric by driving the movement trajectories of guide needles and sinkers according to pattern instructions. Arbitrary loop socks can form loops at arbitrary positions according to human acupoints, thus having a massage and health care function; at the same time, the patterns composed of arbitrary loops can be worn inside out to show individuality, so they are increasingly favored by consumers.

[0003] The existing knitting machines mainly refer to the arbitrary loop sinker devices of sock machines, which mainly include the following two types:

[0004] The first type: When the 6-segment selector fully controls the device to knit half-loop, full-loop, arbitrary loop and other structures, the selection of needles needs to be participated by the 6-segment selector. Therefore, the knitting speed, stability and service life of this device are greatly restricted by the needle selection frequency, load and service life of the 6-segment selector itself.

[0005] The second type: An arbitrary loop sinker device composed of a 4-segment selector. When this device controls the sinker to knit an arbitrary loop structure, the selection of needles needs to be participated by the 4-segment selector. When knitting an arbitrary loop structure, the fastest knitting speed of this device is restricted by the 4-segment selector, and it will only be 2 / 3 of the first type of arbitrary loop sinker device mentioned above.

[0006] In view of this, the inventor of this case has conducted in-depth research on the above problems, and thus this case is generated on how to improve the knitting speed, stability and service life of the arbitrary loop sinker device. Summary of the Invention

[0007] The present invention provides an arbitrary loop sinker device for knitting machines with fast knitting speed, good stability and long service life.

[0008] An arbitrary terry sinker cover device for knitting machinery, including a sinker cover housing, a selector is installed on the side of the sinker cover housing, a left knife control device is provided on one side of the selector, and a right knife control device is provided on the other side. The bottom of the sinker cover housing is installed with inner eyebrows and outer eyebrows for loop formation. Inside the annular structure between the inner eyebrows and the outer eyebrows, an elastic outer eyebrow, a left eyebrow, a left dividing needle eyebrow, a right dividing needle eyebrow, and a right eyebrow are sequentially installed; the left knife control device includes: a left knife cylinder, a cylinder push rod is provided on the left knife cylinder, the cylinder push rod abuts against the left knife fixing plate, one side of the left knife fixing plate cooperates with the left knife positioning ring, and the other side is connected to the sinker cover housing through a left knife positioning screw. A left knife is connected to one side of the left knife fixing plate between the left knife positioning ring and the left knife positioning screw, and a left pull spring pin is installed on the other side. One end of the left return spring is connected to the left pull spring pin, and the other end of the left return spring is connected to the left knife cylinder; the right knife control device includes: a right knife cylinder, a cylinder push rod is provided on the right knife cylinder, the cylinder push rod abuts against the right knife fixing plate, one side of the right knife fixing plate cooperates with the right knife positioning ring, and the other side is connected to the sinker cover housing through a right knife positioning screw. A right knife is connected to one side of the right knife fixing plate between the right knife positioning ring and the right knife positioning screw, and a right pull spring pin is installed on the other side. One end of the right return spring is connected to the right pull spring pin, and the other end of the right return spring is connected to the right knife cylinder. This arbitrary terry sinker cover device for knitting machinery mainly uses the knitting needles controlled by the selector to cooperate with the sinker to control the yarn to form terries at arbitrary positions relative to the left eyebrow, left dividing needle eyebrow, right dividing needle eyebrow, and right eyebrow, achieving the technical purpose of high-speed knitting. When knitting semi-terries and full terries, the selector does not need to work, and the left and right knives directly control the running track of the sinker by entering and exiting. The arbitrary terry sinker cover device with the same knitting speed and stability as the conventional terry machine greatly improves the service life and equipment stability.

[0009] An elastic eyebrow is installed on the radial side of the sinker cover housing, and the elastic eyebrow is connected to an elastic eyebrow sliding bracket, and the elastic eyebrow sliding bracket slides relative to the radial chute of the sinker cover housing to control the elasticity of the elastic thread.

[0010] A door eyebrow flush with the radial direction is installed on the inner eyebrow, and the door eyebrow is connected to the sinker cover housing through a door eyebrow fixing plate.

[0011] The left dividing needle eyebrow, right dividing needle eyebrow, left eyebrow, right eyebrow, outer eyebrow, inner eyebrow, and elastic outer eyebrow are all fixed to the inner end face of the sinker cover housing by screws to improve the stability of the device.

[0012] The top of the selector is connected to the adjustment groove on the selector plate by screws. The selector plate is fixedly connected to the sinker cover housing, and the radial position of the selector is adjusted through the adjustment groove to control the control accuracy of the guide needle piece.

[0013] As a structural preference, the selector is a 6-segment selector.

[0014] A method for knitting an arbitrary terry stitch using a terry sinker device for knitting machines to achieve the knitting of an arbitrary terry stitch pattern. The knitting method involves preparing a matching pattern instruction according to the contour of the arbitrary terry stitch pattern. According to the pattern instruction, the selector drives the corresponding guide blade on the selector to move radially. At the same time, the guide blade rotates synchronously under the drive of the needle cylinder of the knitting machine. When knitting in the forward direction (i.e., clockwise knitting), the upper tip of the guide blade rotates to the left needle eyebrow, slides relative to the inner contour of the left needle eyebrow, and then is relayed by the left eyebrow and slides relative to the outer contour of the left eyebrow. While the guide blade is moving, it drives the rear foot on the sinker blade located in the same slot to move radially, thereby realizing the operation of the yarn raising trajectory of the knitting needle controlled by the selector. When knitting in the reverse direction (i.e., counterclockwise knitting), the upper tip of the guide blade rotates to the right needle eyebrow, slides relative to the inner contour of the right needle eyebrow, and then is relayed by the right eyebrow and slides relative to the outer contour of the right eyebrow. While the guide blade is moving, it drives the rear foot on the sinker blade located in the same slot to move radially, thereby realizing the operation of the yarn raising trajectory of the knitting needle. During the knitting process, for plain weave, since there is no pattern instruction, the selector does not participate in the work, and there is no radial driving force on the corresponding guide blade. Under the action of centrifugal force, the corresponding guide blade slides relative to the inner contour of the outer eyebrow and has no radial contact with the sinker blade located in the same slot. Under the action of centrifugal force, the rear foot of the corresponding sinker blade slides relative to the outer contour of the inner eyebrow, thereby realizing the operation of the plain weave trajectory of the knitting needle yarn and achieving the knitting of an arbitrary terry stitch pattern. That is, in any row of the fabric, a tissue with half terry and half plain weave achieves the knitting effect of a semi-terry tissue. It can also be that in any row of the fabric, all terry stitch patterns achieve the knitting effect of a full-terry tissue.

[0015] A knitting method for realizing half - loop fabric structure by using an arbitrary loop sinker device for knitting machines. According to the position of the half - loop in the fabric, back - foot loop sinker pieces are arranged correspondingly, and a matching pattern instruction is compiled. When running forward, the left knife is driven by the left - knife cylinder, limited by the left - knife positioning ring, rotates to the preset working position, and pushes the back - foot loop sinker pieces to move radially. At the same time, the back - foot loop sinker pieces rotate synchronously driven by the needle cylinder, and the back feet of all back - foot loop sinker pieces slide relative to the inner contour of the left eyebrow, thus realizing the operation of the yarn - raising trajectory of the knitting needles. When running backward, the right knife is driven by the right - knife cylinder, limited by the right - knife positioning ring, rotates to the preset working position, and pushes the back - foot loop sinker pieces to move radially. At the same time, the back - foot loop sinker pieces rotate synchronously driven by the needle cylinder, and the back feet of all back - foot loop sinker pieces slide relative to the inner contour of the right eyebrow, thus realizing the operation of the yarn - raising trajectory of the knitting needles. During the knitting process for plain weave, non - back - foot loop sinker pieces are arranged correspondingly. Whether the left knife and the right knife participate in the work or not, the non - back - foot loop sinker pieces have no contact with the left knife and the right knife. Under the action of centrifugal force, the back feet of the corresponding non - back - foot loop sinker pieces slide relative to the outer contour of the inner eyebrow, realizing the operation of the plain - weave trajectory of the knitting yarn. Thus, a fabric with half - loop and half - plain - weave in one row forms a knitting effect of half - loop fabric structure.

[0016] A knitting method for realizing full - loop fabric structure by using an arbitrary loop sinker device for knitting machines. When the fabric is of full - loop fabric structure, all sinker pieces need to use back - foot sinker pieces. According to the position of the full - loop in the fabric, a matching pattern instruction is compiled. When running forward, the left knife is driven by the left - knife cylinder, limited by the left - knife positioning ring, rotates to the preset working position, and pushes the back - foot sinker pieces to move radially. At the same time, the back - foot sinker pieces rotate synchronously driven by the needle cylinder, and the back feet of all back - foot sinker pieces slide relative to the inner contour of the left eyebrow, thus realizing the operation of the yarn - raising trajectory of the knitting yarn. When running backward, the right knife is driven by the right - knife cylinder, limited by the right - knife positioning ring, rotates to the preset working position, and pushes the back - foot sinker pieces to move radially. At the same time, the back - foot sinker pieces rotate synchronously driven by the needle cylinder, and the back feet of all back - foot sinker pieces slide relative to the inner contour of the right eyebrow, thus realizing the operation of the yarn - raising trajectory of the knitting yarn. Thus, a fabric with all - loop in one row forms a knitting effect of full - loop fabric structure. Among them, when knitting the cross - draw of non - full - loop fabrics, the left knife and the right knife must retract and do not participate in the work.

[0017] From the above implementation solutions, it is not difficult to see that the present invention has the following advantages:

[0018] 1. The present invention still selects a selector, thus effectively ensuring the knitting speed, stability of knitting any terry structure, and the service life of the selector itself. Through the left blade control device and the right blade control device, when knitting semi-terry structure and full-terry structure, the selector does not need to participate in needle selection, thus greatly reducing the usage frequency of the selector, ensuring the service life of the selector, and at the same time being not restricted by the needle selection frequency of the selector, making the knitting speed and stability the same as those of a conventional terry machine.

[0019] 2. The present invention realizes multiple terry knitting structures on the same device, greatly improving the knitting speed, reducing equipment failures, and increasing product quality. BRIEF DESCRIPTION OF THE DRAWINGS

[0029] Such as Figures 1-9Disclosed is an arbitrary terry sinker device for a knitting machine, including a sinker housing 9. A selector 23 is installed on the side of the sinker housing 9. On one side of the selector 23, there is a left knife control device, and on the other side, there is a right knife control device. At the bottom of the sinker housing 9, an inner eyebrow 13 and an outer eyebrow 15 for loop formation are installed. An elastic outer eyebrow 16, a left eyebrow 17, a left dividing needle eyebrow 10, a right dividing needle eyebrow 11, and a right eyebrow 12 are sequentially installed in the annular structure between the inner eyebrow 13 and the outer eyebrow 15.

[0030] The left knife control device includes: a left knife cylinder 2. There is a cylinder ejector rod on the left knife cylinder 2, and the cylinder ejector rod abuts against a left knife fixing plate 21. One side of the left knife fixing plate 21 cooperates with a left knife positioning ring 38, and the other side is connected to the sinker housing 9 through a left knife positioning screw 29. On one side of the left knife fixing plate 21 between the left knife positioning ring 38 and the left knife positioning screw 29, a left knife 20 is connected, and on the other side, a left pull spring pin 39 is installed. One end of a left return spring 40 is connected to the left pull spring pin 39, and the other end of the left return spring 40 is connected to the left knife cylinder 2. The left knife control device controls the rotation angle of the left knife 20 and is reset by the left return spring 40.

[0031] The right knife control device includes: a right knife cylinder 3. There is a cylinder ejector rod on the right knife cylinder 3, and the cylinder ejector rod abuts against a right knife fixing plate 5. One side of the right knife fixing plate 5 cooperates with a right knife positioning ring 6, and the other side is connected to the sinker housing 9 through a right knife positioning screw 41. On one side of the right knife fixing plate 5 between the right knife positioning ring 6 and the right knife positioning screw 41, a right knife 7 is connected, and on the other side, a right pull spring pin 22 is installed. One end of a right return spring 4 is connected to the right pull spring pin 22, and the other end of the right return spring 4 is connected to the right knife cylinder 3. The right knife control device controls the rotation angle of the right knife 7 and is reset by the right return spring 4.

[0032] As a structural preference, an elastic eyebrow 19 is installed on the radial side of the sinker housing 9. The elastic eyebrow 19 is connected to an elastic eyebrow sliding bracket 18, and the elastic eyebrow sliding bracket 18 slides in a chute relative to the radial direction of the sinker housing 9 to adjust the radial position of the elastic eyebrow 19. A door eyebrow 14 with a radial flush is installed on the inner eyebrow 13, and the door eyebrow 14 is connected to the sinker housing 9 through a door eyebrow fixing plate 8.

[0033] In order to further improve the stability and accuracy of the device, the left dividing needle eyebrow 10, the right dividing needle eyebrow 11, the left eyebrow 17, the right eyebrow 12, the outer eyebrow 15, the inner eyebrow 13, and the elastic outer eyebrow 16 are all fixed to the inner end face of the sinker housing 9 by screws. The top of the selector 23 is connected to an adjustment groove 42 on a selector plate 1 through a screw, and the selector plate 1 is fixedly connected to the sinker housing 9. The selector is a 6-segment selector.

[0034] A knitting method for any terry stitch using a terry sinker device for knitting machines. According to the contour of any terry stitch, a matching pattern instruction is compiled. According to the pattern instruction, the selector 23 drives the corresponding guide blade 25 on the selector 23 to move radially, and at the same time, the guide blade 25 rotates synchronously under the drive of the needle cylinder of the knitting machine. As Figure 3 When knitting forward, the upper tip 26 of the guide blade 25 rotates to the left knitting needle eyebrow 10, slides relative to the inner contour of the left knitting needle eyebrow 10, and then is relayed by the left eyebrow 17 and slides relative to the outer contour of the left eyebrow 17. While the guide blade 25 is moving, it drives the rear foot 27 on the sinker 28 located in the same slot to move radially, thereby realizing the operation of the yarn raising trajectory of the knitting needle controlled by the selector. The running trajectory of the upper tip 26 of the guide blade is shown as A in the figure, and the running trajectory of the rear foot 27 of the sinker is shown as B in the figure; As Figure 4 When knitting in reverse, the upper tip 26 of the guide blade 25 rotates to the right knitting needle eyebrow 11, slides relative to the inner contour of the right knitting needle eyebrow 11, and then is relayed by the right eyebrow 12 and slides relative to the outer contour of the right eyebrow 12. While the guide blade 25 is moving, it drives the rear foot 27 on the sinker 28 located in the same slot to move radially, thereby realizing the operation of the yarn raising trajectory of the knitting needle. The running trajectory of the upper tip 26 of the guide blade is shown as C in the figure, and the running trajectory of the rear foot 27 of the sinker is shown as D in the figure; During the knitting process for plain weave, since there is no pattern instruction, the selector 23 does not participate in the work, and there is no radial driving force for the corresponding guide blade 25. Under the action of centrifugal force, the corresponding guide blade 25 slides relative to the inner contour of the outer eyebrow 15 and has no radial contact with the sinker 28 located in the same slot. Under the action of centrifugal force, the rear foot 27 of the corresponding sinker 28 slides relative to the outer contour of the inner eyebrow 13, thereby realizing the operation of the yarn plain weave trajectory of the knitting needle. This knitting method for any terry stitch controlled by the selector 23 utilizes the high-speed needle selection performance of the selector 23 to realize the knitting of any terry stitch.

[0035] A knitting method for semi-terry stitch using a terry sinker device for knitting machines. According to the position of the semi-terry of the fabric, the back-foot terry sinkers 30 are arranged correspondingly, and a matching pattern instruction is compiled. As Figure 5 When knitting forward, the left knife 20, under the action of the left knife cylinder 2 and limited by the left knife positioning ring 38, rotates to the preset working position, pushes the back-foot terry sinkers 30 to move radially, and at the same time, the back-foot terry sinkers 30 rotate synchronously under the drive of the needle cylinder. The rear feet 31 of all the back-foot terry sinkers 30 slide relative to the inner contour of the left eyebrow 17, thereby realizing the operation of the yarn raising trajectory of the knitting needle. The selector does not work. The running trajectory of the upper tip 26 of the guide blade is shown as E in the figure, and the running trajectory of the rear foot 31 of the back-foot terry sinker is shown as F in the figure; As Figure 6When reversing, the right bearded knife 7 is under the action of the right bearded knife cylinder 3, limited by the right bearded knife positioning ring 6, rotates to the preset working position, pushes the bearded sinker 30 with a back leg to move radially. At the same time, the bearded sinker 30 with a back leg rotates synchronously driven by the needle cylinder. The back legs 31 of all the bearded sinkers 30 with a back leg slide relative to the inner contour of the right eyebrow 12, thereby realizing the operation of the knitting needle yarn raising trajectory. Its selector does not work. The running trajectory of the upper tip 26 of the guide needle piece is as shown by G in the figure, and the running trajectory of the back leg 31 of the bearded sinker with a back leg is as shown by H in the figure; as Figure 7 During the knitting process for plain weave, the corresponding arrangement is the beardless sinker 33. Whether the left bearded knife and the right bearded knife participate in the work or not, the beardless sinker 33 has no contact with the left bearded knife and the right bearded knife. Under the action of centrifugal force, the back legs 32 of the corresponding beardless sinkers 33 slide relative to the outer contour of the inner eyebrow 13, realizing the operation of the plain weave trajectory of the knitting yarn. Its selector does not work. The running trajectory of the upper tip 26 of the guide needle piece is as shown by J in the figure, and the running trajectory of the back leg 32 of the beardless sinker is as shown by K in the figure. The fabric formed in this way has a half-loop and half-plain weave in one course, achieving the knitting effect of a semi-loop structure. Since this knitting method of the semi-loop structure does not involve a selector in knitting, it reduces the equipment failure rate, extends the service life and improves the equipment stability.

[0036] A knitting method for realizing a full-loop structure using an arbitrary sinker cover device for a knitting machine. When the fabric is a full-loop structure, all sinkers need to use sinkers with back legs. According to the position of the full-loop of the fabric, a matching pattern instruction is compiled, such as Figure 8 When running forward, the left bearded knife 20 is under the action of the left bearded knife cylinder 2, limited by the left bearded knife positioning ring 38, rotates to the preset working position, pushes the bearded sinker 34 with a back leg to move radially. At the same time, the bearded sinker 34 with a back leg rotates synchronously driven by the needle cylinder. The back legs 35 of all the bearded sinkers 34 with a back leg slide relative to the inner contour of the left eyebrow 17, thereby realizing the operation of the knitting needle yarn raising trajectory. Its selector does not work. The running trajectory of the upper tip 26 of the guide needle piece is as shown by L in the figure, and the running trajectory of the back leg 35 of the bearded sinker with a back leg is as shown by M in the figure; as Figure 9 When reversing, the right bearded knife 7 is under the action of the right bearded knife cylinder 3, limited by the right bearded knife positioning ring 6, rotates to the preset working position, pushes the bearded sinker 34 with a back leg to move radially. At the same time, the bearded sinker 34 with a back leg rotates synchronously driven by the needle cylinder. The back legs 35 of all the bearded sinkers 34 with a back leg slide relative to the inner contour of the right eyebrow 12, thereby realizing the operation of the knitting needle yarn raising trajectory. Its selector does not work. The running trajectory of the upper tip 26 of the guide needle piece is as shown by N in the figure, and the running trajectory of the back leg 35 of the bearded sinker with a back leg is as shown by P in the figure. The fabric formed in this way has a full-loop structure in one course, achieving the knitting effect of a full-loop structure. Since this knitting method of the full-loop structure does not involve a selector in knitting, it reduces the equipment failure rate, extends the service life and improves the equipment stability.

A knitting method for realizing full-loop fabric by using an arbitrary sinker cover device for knitting machinery according to claim 1, characterized in that: When the fabric is full-loop fabric, all sinkers need to use sinkers with back feet. According to the position of the full-loop of the fabric, a matching pattern instruction is compiled. When running forward, under the action of the left cutter cylinder (2), the left cutter (20) is limited by the left cutter positioning ring (38) and rotates to a preset working position, pushing the sinkers with back feet (34) to move radially. At the same time, the sinkers with back feet (34) rotate synchronously driven by the needle cylinder. The back feet (35) of all the sinkers with back feet (34) slide relative to the inner contour of the left eyebrow (17), so as to realize the operation of the yarn raising trajectory of the knitting yarn. When running backward, under the action of the right cutter cylinder (3), the right cutter (7) is limited by the right cutter positioning ring (6) and rotates to a preset working position, pushing the sinkers with back feet (34) to move radially. At the same time, the sinkers with back feet (34) rotate synchronously driven by the needle cylinder. The back feet (35) of all the sinkers with back feet (34) slide relative to the inner contour of the right eyebrow (12), so as to realize the operation of the yarn raising trajectory of the knitting yarn.
