Abstract
Description
Technical Field
[0001] This utility model relates to the field of glove machines, and in particular to a double-sided thread clamping scissor device and a glove machine. Background Technology
[0002] Current glove-making machines require cutting the yarn after knitting one finger and before knitting the next. This ensures straight fingers and prevents them from connecting. Otherwise, the uncut yarn would connect the fingers to the support. Traditional computerized glove machines typically only hold one yarn at a time. While some machines now offer the ability to hold two yarns, this is achieved through a combination of a pressure plate with a pressure hole and a movable plate. The pressure plate is positioned above the movable plate, and the pressure end of the movable plate must cover the pressure hole to hold two yarns simultaneously. However, because the movable plate is below the pressure plate, its rotation pulls up the yarn below it. This lower yarn, connected to the fabric, causes the fabric to sag upwards, tightening the loops and making it difficult for the needles to unravel, thus affecting the continuity of the knitting process. Utility Model Content
[0003] This utility model provides a double-sided thread clamping scissor device, which sets the swing clamping plate above the lower thread clamping plate. This can ensure the stability of the thread clamping while preventing the fabric loops from being pulled tight and affecting the weaving of the fabric.

[0037] Compared with the prior art, the beneficial effects of this utility model are as follows:
[0038] The lower clamping plate is positioned below the oscillating clamping plate, allowing the rotatable oscillating clamping plate's thread-pulling end to rotate above the lower clamping plate. This makes it easier to tighten the yarn above the lower clamping plate. Since the yarn above the lower clamping plate is connected to the grommet, pulling it down will not affect the fabric weaving. Furthermore, the yarn below the lower clamping plate is largely unaffected, and the loop size remains unchanged. Therefore, the coordination between the oscillating clamping plate and the lower clamping plate does not affect the fabric weaving, ensuring the continuity of the weaving process.

[0053] The technical solution of this utility model will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.
[0055] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.
[0056] This utility model embodiment provides a double-sided wire clamping scissor device, such as Figure 1-2 As shown, the assembly includes a scissor base 1, a transmission assembly 2, a clamping drive assembly 3, scissors 4, a hook 5, and a thread clamping assembly 6. The scissor base 1 has a first mounting surface 101 on its upper end. Both the scissors 4 and the thread clamping assembly 6 are mounted on the first mounting surface 101. The thread clamping assembly 6 is located above the scissors 4, and its clamping ends clamp two yarns respectively, which then work with the scissors 4 to cut the yarns. The transmission assembly 2 is located on the scissor base 1 and can be used to drive the scissors 4 to open and close for cutting the yarn, and can also drive the hook 5 from the thread clamping assembly. A single yarn is hooked into the clamping end of one of the yarn clamping components 6, or two yarns are hooked into the clamping end one after the other and clamped for cutting by the scissors 4. The clamping plate drive component 3 is installed on the scissor seat 1 and is used to drive the swinging clamping plate 61 in the yarn clamping component 6 to swing. The swinging clamping plate 61 can swing, while the other clamping plates in the yarn clamping component 6 are fixed. Thus, the two side walls of the swinging clamping plate 61 will cooperate with the fixed clamping plates inside, and cooperate with the transmission component 2 and the hook knife 5 to clamp, cut and release the two yarns.
[0057] Specifically, such as Figures 3-7As shown, the yarn clamping assembly 6 includes a rotatable swing clamp 61 and a fixedly disposed lower clamping plate 62. The swing clamp 61 includes a driving end and a yarn-pulling end. The clamp driving assembly 3 is connected to the driving end so that the yarn-pulling end swings around its rotation axis. The lower clamping plate 62 has a lower pressure hole. The two ends of the yarn-pulling end cooperate with the lower pressure hole to clamp multiple yarns. In order to solve the problem of the coil being pulled in when clamping the yarn, in this embodiment, the lower clamping plate 62 is located below the swing clamp 61, so that the yarn-pulling end of the rotatable swing clamp 61 rotates above the lower clamping plate 62, making it easy to tighten the yarn above the lower clamping plate 62. The yarn above the lower clamping plate 62 is connected to the grommet, so being pulled down will not affect the weaving of the fabric. The yarn below the lower clamping plate 62 is basically unaffected, and the coil size will not change. Therefore, the cooperation between the swing clamp 61 and the lower clamping plate 62 will not affect the weaving of the fabric and can ensure the continuity of the weaving.
[0058] Specifically, the yarn-pulling end has a first yarn-pulling end 611 and a second yarn-pulling end 612. The lower clamping plate 62, at its end away from the drive end, has a first lower clamping arm 621 and a second lower clamping arm 622 spaced apart. The first lower clamping arm 621 and the second lower clamping arm 622 form a lower pressing hole. Because the swing clamping plate 61 can swing, the positions of the first yarn-pulling end 611 and the second yarn-pulling end 612 can be varied. Thus, the first lower clamping arm 621 and the movable first yarn-pulling end 611 cooperate to clamp and release the first yarn at a first point. The second lower clamping arm... The second thread-pulling end 612, which can be moved to a variable position, is used in conjunction with the first thread-pulling end 622 to clamp and release the second yarn at the first point, thereby enabling clamping and releasing of the two yarns at the first point. Of course, the first lower clamping arm 621 and the second lower clamping arm 622 form a lower pressing hole. When the thread-pulling end of the swing clamping piece 61 covers the lower pressing hole downwards, the first thread-pulling end 611 and the first lower clamping arm 621 clamp the first yarn, and at the same time, the second thread-pulling end 612 and the second lower clamping arm 622 clamp the second yarn. Then, the thread-pulling end can be rotated accordingly according to the cutting needs.
[0059] Specifically, the yarn clamping assembly 6 also includes an upper yarn clamping plate 63, which is fixedly disposed above the swing clamping plate 61. On the one hand, it is used to further press the swing clamping plate 61, so that the swing clamping plate 61 swings stably between the upper yarn clamping plate 63 and the lower yarn clamping plate 62. On the other hand, the upper yarn clamping plate 63 can also cooperate with the swing clamping plate 61 to further clamp the two yarns, thereby forming a second clamping point. Specifically, the end of the upper yarn clamping plate 63 away from the driving end has a first upper clamping arm 631 and a second upper clamping arm 631 that are spaced apart from each other. The second upper clamping arm 632, also because the swinging clamping plate 61 can swing, allows the positions of the first yarn-pulling end 611 and the second yarn-pulling end 612 to be variable. Thus, the first upper clamping arm 631 and the variable-position first yarn-pulling end 611 work together to clamp and release the first yarn at a second point, and the second upper clamping arm 632 and the variable-position second yarn-pulling end 612 work together to clamp and release the second yarn at a second point, thereby enabling clamping and releasing of the two yarns at their second points. It should be noted that the first yarn passes sequentially through the inner side of the first upper clamping arm 631 and the outer side of the first yarn-pulling end 611, and is then clamped by the first upper clamping arm 631 and the first yarn-pulling end 611. Similarly, the second yarn passes sequentially through the inner side of the second upper clamping arm 632 and the outer side of the second yarn-pulling end 612, and is then clamped by the second upper clamping arm 632 and the second yarn-pulling end 612.
[0060] Specifically, such as Figure 5 and Figure 7 As shown, the yarn-pulling end has a first connecting section and a second connecting section on both sides. The first connecting section is located on the same side as the first yarn-pulling end 611, and the second connecting section is located on the same side as the second yarn-pulling end 612. The close ends of the first connecting section and the second connecting section are connected to form a tip, and the far ends are connected to the first yarn-pulling end 611 and the second yarn-pulling end 612 respectively, to form a first outer protrusion 614 and a second outer protrusion 615. The first outer protrusion 614 is used to prevent the yarn at the first yarn-pulling end 611 from coming off at the first yarn-pulling end 611, and the second outer protrusion 615 is used to prevent... The yarn at the second thread-pulling end 612 exits from the second thread-pulling end 612, thus ensuring stable yarn clamping. Correspondingly, the inner sidewalls of the first upper clamping arm 631 and the first lower clamping arm 621 form a first inner protrusion 623, and the inner sidewalls of the second upper clamping arm 632 and the second lower clamping arm 622 form a second inner protrusion 624. The first outer protrusion 614 and the first inner protrusion 623 respectively restrict the yarn in the lower pressing hole from disengaging therefrom, and the second outer protrusion 615 and the second inner protrusion 624 respectively restrict the yarn at the lower pressing hole from disengaging therefrom, ensuring stable yarn clamping. Furthermore, the first outer protrusion 614 and the second outer protrusion 615 are connected to the outer sidewalls of the first thread-pulling end 611 and the second thread-pulling end 612 through arc-shaped surfaces. The arc-shaped surfaces are not only aesthetically pleasing but also facilitate the transition during part processing.
[0061] Specifically, the installation method of the upper clamping piece 63, the swinging clamping piece 61, the lower clamping piece 62, and the scissors 4 is as follows: The driving end is provided with a driving hole 616. The swinging clamping piece 61 is provided with a first guide hole 617, a rotating hole 618, and a second guide hole 619. The first guide hole 617 and the second guide hole 619 are respectively located on both sides of the rotating hole 618. The driving end of the clamping piece driving assembly 3 is provided with a swinging rod 37. In this embodiment, the driving hole 616 is an oblong hole, and the swinging rod 37 is inserted into the driving hole 616. Correspondingly, since the upper clamping piece 63, the swinging clamping piece 61, and the lower clamping piece 62 are arranged sequentially from top to bottom... Only the swing clamp 61 can rotate. Correspondingly, the first mounting surface 101 is provided with a first mounting shaft 10 and a second mounting shaft 11. The transmission assembly 2 includes a drive shaft 21. The scissors 4 include fixed scissors 41 and flexible scissors 42. The flexible scissors 42 is provided with mounting holes. The flexible scissors 42 is located above the fixed scissors 41. The first mounting shaft 10 passes through the mounting end of the fixed scissors 41, the first through hole of the lower clamping plate 62, the first guide hole 617, and the first through hole on the upper clamping plate 63 in sequence. The second mounting shaft 11 fixes the mounting end of the scissors 41 and the second through hole on the lower clamping plate 62 in sequence. The first mounting shaft 10 and the second through hole on the rotating hole 618 and the upper clamping plate 63 are connected. The drive shaft 21 passes through the fixed scissors 41, and its upper end is set as a waist-shaped column. The waist-shaped column passes through the waist-shaped hole on the flexible scissors 42 that matches the waist-shaped column, the third through hole on the lower clamping plate 62, the second guide hole 619, and the third through hole on the upper clamping plate 63 in sequence. The first mounting shaft 10 and the waist-shaped column can move relative to the first guide hole 617 and the second guide hole 619, respectively. Thus, under the action of the swing rod 37, the swing rod 37 acts on the drive hole 616, so that the swinging clamping plate 61 can rotate relative to the second mounting shaft 11 through the rotating hole 618. Furthermore, the first mounting shaft 10 and the first guide hole 617 cooperate with the waist-shaped column and the second guide hole 619, which can play a certain role in fixing and guiding the swing of the swing clamp 61, making it swing stably. The upper clamping plate 63 and the lower clamping plate 62 are fixed by the action of the first mounting shaft 10, the second mounting shaft 11 and the waist-shaped column. The rotation of the waist-shaped column will drive the movable scissors 42 to rotate relative to the fixed scissors 41. Since the third through hole on the upper clamping plate 63 and the lower clamping plate 62 is a circular through hole, the waist-shaped column will only rotate in the circular through hole and will not drive the upper clamping plate 63 and the lower clamping plate 62 to move. It should be noted that the swing clamp 61 rotates relative to the second mounting shaft 11, and the second mounting shaft 11 is fixedly installed on the scissor 4 frame, so that the swing clamp 61 rotates more accurately and smoothly.
[0062] Furthermore, the yarn-pulling end cooperates with the lower pressing hole to clamp two yarns, and both can be used with scissors 4 to cut the yarn. The user can continuously cut the yarn at one end of the yarn-pulling end. It can be seen that no matter which end of the yarn the scissors 4 cuts, the free end of the yarn after cutting (the cut point of the yarn) will be located below the lower clamping plate 62. For example, after the first yarn-pulling end 611 and the second yarn-pulling end 612 have each clamped a cut yarn with the first lower clamping arm 621 and the second lower clamping arm 622 respectively, the user can continuously release and cut the yarn at one of the yarn-pulling ends (the yarn needs to be released before cutting, and then clamped for a new cutting). Although the scissors 4 will cut this yarn, the other clamped yarn will remain free. If the yarn end is not easily brought in and is cut again, leaving a small piece of yarn, this small piece of yarn will accumulate at the scissors 4, causing the yarn clamp to become loose. This will affect the swing stroke of the clamping plate and the scissors 4, resulting in incomplete operation and affecting normal weaving. Therefore, in this embodiment, a second mounting surface 102 is provided on the upper end of the scissors seat 1, and an air blowing component 7 is provided on the second mounting surface 102. The air blowing component 7 is located below the cutting edge of the scissors 4, and its air blowing port faces the lower pressing hole to blow the free end of the yarn into the lower pressing hole, preventing the scissors 4 from contacting the free end (cutting end) of the yarn. This avoids the situation where the free end of the other yarn is cut again and a small piece of yarn is left when continuously cutting the yarn at one end of the yarn puller, ensuring that the scissors device can stably and continuously clamp and cut. Specifically, the air blowing component 7 is set as an air nozzle with an external air pipe.
[0063] Furthermore, the yarn-pulling end is provided with a receiving hole 613, which is located above the lower pressing hole and the two are connected to form a receiving cavity. The receiving cavity formed by the receiving hole 613 and the lower pressing hole is larger, which allows the free end of the yarn blown by the air blowing element 7 to completely enter the receiving cavity and enter to a deeper depth, away from the scissors 4.
[0064] Specifically, the clamp drive assembly 3 includes a mounting plate 31, a drive member 32, a drive gear 33, a driven gear 34, and a rotating shaft 36. The mounting plate 31 is connected to the scissor seat 1, the drive member 32 is connected to the mounting plate 31, the rotating shaft 36 is rotatably mounted on the mounting plate 31, the drive gear 33 is mounted on the output shaft of the drive member 32, the driven gear 34 meshes with the drive gear 33, the end of the rotating shaft 36 away from the swing clamp 61 is connected to the driven gear 34, and the end of the rotating shaft 36 near the swing clamp 61 is provided with a swing rod 37. Under the drive of the drive member 32, the drive gear 33, and the driven gear 34, the rotating shaft 36 rotates. The swing rod 37 cooperates with the drive hole 616 at the swing clamp 61, so that the swing clamp 61 swings along its rotation axis. Specifically, a sensor 35 is also provided on the mounting plate 31. The sensing end of the sensor 35 faces the driven gear 34 and is used to determine the zero position of the driven gear 34 and the swing clamp 61, so that the wire clamping assembly 6 starts from the zero position every time it starts working, which facilitates the stable operation of the entire scissor device. The sensor 35 is an existing signal sensor 35, and a sensing plate is provided on the corresponding driven gear 34. The two work together to determine the zero position of the driven gear 34 and the swing clamp 61. Furthermore, since the swing clamp 61 swings only within a certain angle range, the corresponding driven gear 34 only needs to rotate a certain angle. Therefore, the driven gear 34 is set as an incomplete gear, and the angle between the two ends of the incomplete gear and its center line is no greater than 90 degrees. This satisfies the swing angle of the swing clamp 61 and reduces the installation space occupied by the driven gear 34. The driving component 32 can be a motor.
[0065] Specifically, the transmission component 2 in this utility model has the same structure as the transmission component 2 in the scissors 4 mechanism with double-layer wire clamping function disclosed in CN222332227U, which can drive the scissors 4 to open and close and drive the hook 5 to hook the wire. Its structure will not be described in detail here.
[0066] For ease of description, the first yarn-pulling end 611 and the first lower clamping arm 621 constitute the first clamping part, and the second yarn-pulling end 612 and the second lower clamping arm 622 constitute the second clamping part. Specifically, the movement of the upper clamping plate 63, the swinging clamping plate 61, the lower clamping plate 62, and the scissors 4 is as follows: When the fabric weaving begins, the scissors 4 is in a closed state, and the two ends of the yarn-pulling end in the yarn clamping assembly 6 and the lower pressing hole each clamp the yarn on different yarn feeders, such as... Figure 8 As shown, at this time, sensor 35 is in the zero position (driven gear 34 and swing clamp 61 are in the zero position). When it is necessary to release a yarn end (free end) during the weaving process, the yarn release action is explained using the first clamping part as an example. First, open the scissors 4, that is, under the drive of the drive shaft 21, the movable scissors 42 rotate in the N direction (e.g., Figure 9Then, driven by the drive component 32 within the clamp drive assembly 3, the drive gear 33 meshes with the driven gear 34, driving the rotating shaft 36 and the swing rod 37 to rotate. Then, through the engagement of the swing rod 37 with the drive hole 616, the swing clamp 61 is pushed to rotate around the second mounting shaft 11 in the N direction. At this time, the first lower clamp arm 621 and the first wire-feeding end 611 are spaced apart to form a first wire-feeding gap 8 (e.g., ...). Figure 10 As shown), the yarn end clamped in the first clamping part can be released from the first feed gap 8, achieving the purpose of feeding yarn from the first clamping part. Similarly, if the second clamping part feeds yarn in the same way, first open the scissors 4, that is, under the drive of the drive shaft 21, the movable scissors 42 rotate in the N direction (as shown). Figure 9 Then, driven by the drive unit 32, the swing rod 37 pushes the swing clamp 61 to rotate in the M direction. At this time, the second lower clamp arm 622 and the second wire-feeding end 612 are spaced apart to form a second wire-feeding gap 9 (e.g. Figure 11 As shown), the yarn end clamped at the second clamping part can be released from the second feeding gap 9, thus achieving the purpose of feeding yarn from the second clamping part.
[0067] If it is necessary to cut a yarn during the knitting process, let's take the cutting of the yarn at the first clamping part as an example to illustrate the yarn cutting action of the first clamping part. When cutting the yarn, the first clamping part must be in the yarn-releasing state, that is, a first yarn-releasing gap 8 must be left at the first clamping part (e.g., Figure 10 The flexible shears 42, under the action of the drive shaft 21, first rotate in the N direction to a certain opening (the opening for the hook 5 to pass through). The yarn to be cut is hooked into the first feed gap 8 by the hook 5. Then, under the drive of the drive unit 32, the swing rod 37 pushes the swing clamp 61 to rotate in the M direction. At this time, the yarn to be cut is pushed in the M direction by the first thread-pulling end 611 of the swing clamp 61 until it is clamped by the first thread-pulling end 611 and the first lower clamping arm 621 at the lower clamping plate 62. After that, the flexible shears 42, under the action of the drive shaft 21, rotates in the M direction to cut the clamped yarn, completing the cutting action of the first clamping part. Figure 8 As shown. Next, the wire cutting action is performed at the second clamping part. During the wire cutting, the second clamping part must be in the wire feeding state, that is, a second wire feeding gap 9 is left at the second clamping part (e.g., Figure 11 The flexible shears 42, under the action of the drive shaft 21, first rotate in the N direction to a certain opening (the opening for the hook 5 to pass through). The yarn to be cut is hooked into the second feed gap 9 by the hook 5. Then, under the drive of the drive unit 32, the swing rod 37 pushes the swing clamp 61 to rotate in the N direction. At this time, the yarn to be cut is pushed in the N direction by the second thread-pulling end 612 of the swing clamp 61 until it is clamped by the second thread-pulling end 612 and the second lower clamping arm 622 at the lower clamping plate 62. After that, the flexible shears 42, under the action of the drive shaft 21, rotates in the M direction to cut the clamped yarn, completing the cutting action of the second clamping part. Figure 8 As shown.
