Description

Technical Field

[0001] This utility model relates to the field of warp threading machines, and in particular to an automatic warp threading machine. Background Technology

[0002] In the textile industry, automatic warping machines are key equipment connecting spinning and weaving. Their core function is to achieve precise threading of yarn into heddles and reeds through the coordinated action of yarn feeding, guiding, and yarn exit components, which directly affects the production efficiency and finished product quality of fabrics.

[0003] In the prior art, patent publication number CN222226754U discloses a yarn feeding device for a warping machine, including a transmission box, a bracket, a vertical plate, a drive motor, a yarn guiding plate, a roller frame, and a yarn output plate. The bottom of the transmission box is fixedly connected to the left side of the top of the bracket, and the bottom of the vertical plate is fixedly connected to the right side of the top of the bracket. The drive motor is fixedly installed on the front side of the left side of the transmission box, and the output end of the drive motor is connected to the left side of the roller frame. The left side of the yarn guiding plate is fixedly connected to the top of the right side of the transmission box, and the right side of the yarn guiding plate is fixedly connected to the top of the left side of the bracket. The yarn output plate is located on the front side of the top of the bracket. A connecting groove is provided on the front side of both the transmission box and the vertical plate. A movable plate is movably connected to the bottom of the inner wall of the connecting groove. The movable plate is located on the left and right sides of the yarn output plate. A snap-fit ​​assembly is provided on both sides of the yarn output plate, and a limit assembly is provided inside the connecting groove.

[0004] The above solution has the following problems: 1. The roller frame lacks a tension adjustment mechanism, making it impossible to dynamically adjust the tension according to the yarn characteristics, and making it difficult to adapt to the stable transmission of multi-specification yarns; 2. The yarn guide plate is rigidly fixed to the transmission box and bracket, and there is no quick disassembly and assembly structure between it and the upright plate. The process of replacing the yarn guide plate is cumbersome and prone to installation and positioning deviation.

[0005] 3. The yarn exit plate lacks a combing function to further improve the straightness of the yarn. Utility Model Content

[0006] To address the current lack of tension adjustment mechanisms, which prevents dynamic tension adjustment based on yarn characteristics and hinders stable transmission of multi-specification yarns, this invention provides an automatic warping machine.

[0007] To solve the above problems, the technical solution adopted by this utility model is as follows: An automatic warping machine includes a base with vertically mounted plates on both sides. A yarn guide plate is installed in the center of the top surface of each plate. A roller frame is rotatably mounted in the center of each plate. A rotating platform is connected to the roller frame. The rotating platform is installed on one side of one of the plates. A yarn exit plate is mounted at the front end of the base via a linear translation mechanism. This automatic warping machine, through the roller frame connected to the rotating platform, can assist in dynamically adjusting the yarn transmission tension, solving the problem of existing roller frames lacking a tension adjustment mechanism and being unable to stably transmit multiple specifications of yarn. The yarn exit plate, mounted at the front end of the base via a linear translation mechanism, can assist in combing the yarn during translation to improve straightness, compensating for the lack of combing function in existing yarn exit plates.

[0008] Preferably, the roller frame includes two mounting plates; a rotating shaft is fixedly installed on the center of the outer side of each mounting plate; the two rotating shafts are rotatably mounted on two vertical plates respectively; two roller shafts are rotatably mounted between the two mounting plates; the two roller shafts are rotatably mounted at both ends of the mounting plates respectively; each roller shaft is connected to a motor; the motor is mounted on the mounting plate. Each of the two roller shafts corresponds to an independent motor, and the speed can be adjusted independently to dynamically adjust the transmission tension according to the yarn thickness, elasticity, and other characteristics, effectively avoiding yarn breakage or tangling due to unsuitable tension, and adapting to the stable transmission of multiple specifications of yarn; at the same time, the mounting plate can drive the entire roller frame to rotate on the vertical plate through the outer rotating shaft, which can adjust the angle of the roller frame to adapt to different yarn guiding tension requirements.

[0009] Preferably, the roller shaft has several guide grooves along its length to cooperate with the yarn guide plate. These guide grooves allow multiple yarns drawn from the yarn guide plate to be embedded into their respective independent guide grooves, achieving an independent yarn guide channel for each yarn. This effectively avoids mutual friction and tangling during the transmission of multiple yarns. Simultaneously, the cooperation between the guide grooves and the yarn guide plate precisely defines the yarn guide path, reducing yarn transmission deviation and ensuring the accuracy of subsequent roller guide and yarn exit from the yarn exit plate, further improving the warping quality.

[0010] Preferably, one of the upright plates has a through hole at its upper center; the through hole includes a circular hole; the circular hole has an elongated hole along its radial direction; a cylinder is fixedly mounted on one end of the yarn guide plate; a radial rod is fixedly mounted on the end of the cylinder along its radial direction; the length of the cylinder minus the width of the radial rod equals the thickness of the upright plate; the end of the yarn guide plate away from the cylinder is connected to another upright plate via a quick-release assembly. One end of the yarn guide plate is inserted into the circular hole of the upright plate through the cylinder, and after rotation, the radial rod is locked on the outside of the upright plate. The matching design of the length of the cylinder and the width of the radial rod allows the radial rod to fit against the upright plate, preventing the yarn guide plate from moving axially; the other end is connected to the opposite upright plate via the quick-release assembly, thus completing the assembly and disassembly of the yarn guide plate. This operation is convenient and ensures consistent installation position, effectively avoiding the influence of cumbersome assembly and disassembly or positioning deviation on the yarn guide path. It adapts to the need for quick replacement of yarn guide plates of different specifications, improving equipment adjustment efficiency.

[0011] Preferably, the quick-release assembly includes a bolt and a second cylinder fixedly disposed at the end of the yarn guide plate away from the first cylinder; a connecting block is slidably disposed on the second cylinder; a second through hole is formed on the connecting block; a third through hole is formed on the second cylinder corresponding to the second through hole; a clearance groove is formed on the upright plate to cooperate with the connecting block; a threaded hole is provided at the bottom of the clearance groove; the bolt passes through the second and third through holes and is threaded into the threaded hole. In the quick-release assembly, the connecting block can slide along the second cylinder and embed into the clearance groove of the upright plate to achieve pre-positioning; the bolt passes through the second through hole of the connecting block and the third through hole of the second cylinder and is screwed into the threaded hole of the clearance groove to be fixed. Only a single bolt needs to be turned to complete the assembly and disassembly of the yarn guide plate, making the operation convenient; at the same time, the combination of the pre-positioning structure and the bolt fixation can ensure the consistency of the installation position of the yarn guide plate, avoid positioning deviation from affecting the yarn guide path, and adapt to the needs of quick replacement of yarn guide plates of different specifications.

[0012] Preferably, the center line of the radial rod is parallel to the three axes of the through hole. This parallelism ensures that when one end of the yarn guide plate is positioned by the radial rod and the other end is fixed by the quick-release assembly bolts, the positioning directions at both ends are consistent, preventing tilting during yarn guide plate installation. It also simplifies the installation and alignment process, eliminating the need for repeated angle adjustments. This improves the ease of installation and removal of the yarn guide plate, ensures its stable posture, prevents deviations in positioning direction from affecting the yarn transmission path, and guarantees yarn guiding accuracy.

[0013] Preferably, the linear translation mechanism includes two rodless cylinders; the two rodless cylinders are respectively fixedly installed at the left and right ends of the front side of the base; the pistons of the rodless cylinders are connected to the yarn outlet plate through a bracket. The two rodless cylinders are symmetrically arranged at both ends of the front side of the base, and synchronously drive the yarn outlet plate to translate through the bracket, which can avoid the yarn outlet plate offset caused by unilateral drive and ensure translation stability; the rodless cylinders drive the yarn outlet plate to reciprocate, which can further straighten the yarn.

[0014] Preferably, the linear translation mechanism moves in a direction perpendicular to the center line of the yarn feeder. This perpendicular movement allows the yarn feeder to reciprocate along the fabric width direction to comb the yarn.

[0015] Preferably, the support includes a square rod; the square rod has four through holes; the support is connected to the piston of the rodless cylinder and the yarn outlet plate by bolts. The support adopts a square rod structure, which, together with the four through holes, connects the piston of the rodless cylinder and the yarn outlet plate by bolts. This not only improves the structural stability by using the square rod to prevent the yarn outlet plate from shifting, but also allows for convenient disassembly and subsequent adjustment by using bolts.

[0016] Preferably, the base has a mounting groove for the rodless cylinder; the rodless cylinder is bolted into the mounting groove. The mounting groove on the base can position the rodless cylinder, and the bolt fixing can prevent the rodless cylinder from shifting or shaking during operation. At the same time, it facilitates the disassembly and maintenance of the rodless cylinder and ensures the stability of the yarn feeding plate translation drive.

[0017] As can be seen from the above technical solutions, the advantages of this utility model include: the automatic warping machine connects to a rotating platform via a roller frame, which can assist in dynamically adjusting the yarn transmission tension, solving the problem that existing roller frames lack tension adjustment mechanisms and are difficult to adapt to the stable transmission of multi-specification yarns; the yarn output plate is installed at the front end of the base through a linear translation mechanism, which can assist in combing the yarn during translation to improve straightness, making up for the lack of combing function in existing yarn output plates. Two rodless cylinders are symmetrically arranged at both ends of the front side of the base, and synchronously drive the yarn output plate to translate through the bracket, which can avoid the yarn output plate offset caused by unilateral drive and ensure translation stability; the rodless cylinders drive the yarn output plate to move back and forth, which can further comb the straightness of the yarn.

Detailed Implementation

[0026] To make the objectives, features, and advantages of this utility model more apparent and understandable, the technical solutions of this utility model will be clearly and completely described below with reference to the accompanying drawings of the specific embodiments. Obviously, the embodiments described below are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this patent, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this patent.

[0027] like Figure 1-2 As shown, an automatic warping machine includes a base 1, with vertical plates 2 vertically arranged on both sides of the base 1; a yarn guide plate 3 is installed in the middle of the top surface of the vertical plate 2; a roller frame 4 is rotatably arranged in the middle of the vertical plate 2; the roller frame 4 is connected to a rotating platform 5; the rotating platform 5 is installed on one side of one of the vertical plates 2; and a yarn outlet plate 12 is installed at the front end of the base 1 through a linear translation mechanism.

[0028] The automatic warping machine is connected to the rotating platform 5 via the roller frame 4, which can assist in dynamically adjusting the yarn transmission tension, solving the problem that the existing roller frame 4 lacks a tension adjustment mechanism and is difficult to adapt to the stable transmission of multi-specification yarns; the front end of the base 1 is equipped with the yarn output plate 12 through a linear translation mechanism, which can assist in combing the yarn during the translation process to improve straightness, making up for the lack of combing function in the existing yarn output plate 12.

[0029] like Figure 3 and Figure 4 As shown, a through hole 6 is provided at the upper middle part of one of the upright plates 2; the through hole 6 includes a circular hole 601; the circular hole 601 has an elongated hole 602 in the radial direction; a cylinder 301 is fixedly provided at one end of the yarn guide plate 3; a radial rod 302 is fixedly provided at the end of the cylinder 301 in the radial direction; the length of the cylinder 301 minus the width of the radial rod 302 is equal to the thickness of the upright plate 2; the end of the yarn guide plate 3 away from the cylinder 301 is connected to another upright plate 2 through a quick-release assembly. The quick-release assembly includes a bolt 9 and a second cylinder 303 fixedly mounted on the end of the yarn guide plate 3 away from the first cylinder 301; a connecting block 7 is slidably mounted on the second cylinder 303; a second through hole 701 is provided on the connecting block 7; a third through hole 304 is provided on the second cylinder 303 corresponding to the second through hole 701; a clearance groove 8 is provided on the vertical plate 2 to mate with the connecting block 7; a threaded hole 801 is provided at the bottom of the clearance groove 8; the bolt 9 passes through the second through hole 701 and the third through hole 304 and is threaded into the threaded hole 801. The centerline of the radial rod 302 is parallel to the axis of the third through hole 304.

[0030] One end of the yarn guide plate 3 is inserted into the circular hole 601 of the vertical plate 2 through the cylinder 301. After rotation, the radial rod 302 is locked on the outside of the vertical plate 2. The matching design of the length of the cylinder 301 and the width of the radial rod 302 allows the radial rod 302 to fit against the vertical plate 2, preventing the yarn guide plate 3 from moving along the axial direction. The other end is connected to the vertical plate 2 through a quick-release assembly, which can complete the disassembly and assembly of the yarn guide plate 3. The operation is convenient and can ensure the consistency of the installation position. It effectively avoids the yarn guide path being affected by cumbersome disassembly and assembly or positioning deviation. It can adapt to the need for quick replacement of yarn guide plates 3 of different specifications and improve the efficiency of equipment adjustment. In the quick-release assembly, the connecting block 7 can slide along the second cylinder 303 and embed into the clearance groove 8 of the upright plate 2 for pre-positioning. The bolt 9 passes through the second through hole 701 of the connecting block 7 and the third through hole 304 of the second cylinder 303 and is screwed into the threaded hole 801 of the clearance groove 8 for fixation. Only a single bolt 9 needs to be turned to complete the disassembly and assembly of the yarn guide plate 3, making the operation convenient. At the same time, the pre-positioning structure and the fixed combination with the bolt 9 can ensure the consistency of the installation position of the yarn guide plate 3, avoid positioning deviation from affecting the yarn guide path, and adapt to the need for quick replacement of yarn guide plates 3 of different specifications. The center line of the radial rod 302 is parallel to the axis of the third through hole 304, which can ensure that when one end of the yarn guide plate 3 is positioned by the radial rod 302 and the other end is fixed by the bolt 9 of the quick-release assembly, the positioning direction of both ends is consistent, avoiding the tilting of the yarn guide plate 3 during installation. At the same time, it simplifies the installation alignment steps, eliminating the need for repeated angle adjustments, which not only improves the ease of disassembly and assembly of the yarn guide plate 3, but also ensures the stability of the yarn guide plate 3's posture, avoiding the influence of positioning direction deviation on the yarn transmission path and ensuring the accuracy of yarn guidance.

[0031] like Figure 5 As shown, the roller frame 4 includes two mounting plates 401; a rotating shaft 402 is fixedly installed on the middle of the outer side of each mounting plate 401; the two rotating shafts 402 are rotatably mounted on the two vertical plates 2 respectively; two roller shafts 403 are rotatably mounted between the two mounting plates 401; the two roller shafts 403 are rotatably mounted at both ends of the mounting plates 401 respectively; each roller shaft 403 is connected to a motor 404; the motor 404 is mounted on the mounting plate 401. Several guide grooves 405 are provided on the roller shafts 403 along the length direction to cooperate with the yarn guide plate 3.

[0032] Each of the two rollers 403 corresponds to an independent motor 404, whose speed can be adjusted to dynamically adjust the transmission tension according to the yarn thickness, elasticity, and other characteristics. This effectively prevents yarn breakage or tangling due to unsuitable tension and ensures stable transmission of various yarn specifications. Simultaneously, the mounting plate 401, via the outer rotating shaft 402, can drive the roller frame 4 to rotate on the vertical plate 2, adjusting the angle of the roller frame 4 to accommodate different yarn guiding tension requirements. Along the length of the rollers 403, several guide grooves 405 are provided in conjunction with the yarn guide plate 3. This allows multiple yarns led from the yarn guide plate 3 to be embedded into the independent guide grooves 405, achieving an independent yarn guiding channel for each yarn. This effectively prevents mutual friction and tangling during the transmission of multiple yarns. Furthermore, the cooperation between the guide grooves 405 and the yarn guide plate 3 precisely limits the yarn guiding path, reduces yarn transmission deviation, and ensures the accuracy of subsequent yarn guiding by the roller frame 4 and yarn exiting from the yarn exit plate 12, further improving the warping quality.

[0033] like Figure 6 As shown, the linear translation mechanism includes two rodless cylinders 10; the two rodless cylinders 10 are respectively fixedly installed at the left and right ends of the front side of the base 1; the pistons of the rodless cylinders 10 are connected to the yarn outlet plate 12 through the bracket 11. The moving direction of the linear translation mechanism is perpendicular to the center line of the yarn guide plate 3. The bracket 11 includes a square rod 1101; a through hole 1102 is opened on the square rod 1101; the bracket 11 is connected to the piston of the rodless cylinder 10 and the yarn outlet plate 12 by bolts. The base 1 has a mounting groove 101 to accommodate the rodless cylinder 10; the rodless cylinder 10 is installed in the mounting groove 101 by bolts.

[0034] Two rodless cylinders 10 are symmetrically arranged at both ends of the front side of the base 1. They synchronously drive the yarn outlet plate 12 to move horizontally via the bracket 11, preventing displacement of the yarn outlet plate 12 caused by unilateral drive and ensuring translational stability. The rodless cylinders 10 drive the yarn outlet plate 12 to reciprocate, further straightening the yarn. The linear translation mechanism moves perpendicular to the center line of the yarn guide plate 3, allowing the yarn outlet plate 12 to reciprocate along the fabric width direction to straighten the yarn. The bracket 11 adopts a square rod 1101 structure, which, along with through holes 1102, connects the piston of the rodless cylinder 10 to the yarn outlet plate 12 via bolts 9. This structure uses the square rod 1101 to improve structural stability and prevent displacement of the yarn outlet plate 12, while also allowing for convenient disassembly and subsequent adjustment via bolts 9. The mounting slot 101 on the base 1 positions the rodless cylinder 10, and the bolts 9 secure it to prevent displacement and shaking during operation, while also facilitating disassembly and maintenance of the rodless cylinder 10 and ensuring the stability of the translational drive of the yarn outlet plate 12.

[0035] In other alternative embodiments, the linear translation mechanism includes a lead screw and a guide rod. One lead screw is located on one side of the front end of the base 1, and the guide rod is located on the other side of the front end of the base 1. The lead screw is connected to a motor for driving its rotation. The nut of the lead screw is connected to a bracket 11, and the other bracket 11 is slidably mounted on the guide rod.

[0036] The working principle of this built-in warping machine is to achieve precise and stable yarn transmission through the coordinated action of yarn feeding, tension adjustment, carding, and yarn exit. The specific process is as follows: After the yarn is drawn out from the yarn supply end, it first enters the yarn guide plate 3 on the top surface of the vertical plate 2. The yarn guide plate 3 ensures the stability of the installation posture by cooperating with the cylindrical 301 and the radial rod 302 through the through hole 6 and the quick-release assembly, so that the yarn is orderly discharged along the preset path. The discharged yarn is embedded into the guide groove 405 of the roller shaft 403 of the roller frame 4, so as to realize the independent separation of individual yarns and avoid mutual entanglement.

[0037] Subsequently, the yarn enters the double roller shaft 403 between the two mounting plates 401. The roller frame 4 can be adjusted as a whole through the rotating platform 5. At the same time, the two roller shafts 403 are driven by independent motors 404. By adjusting the speed difference between the two roller shafts 403 and the angle of the roller frame 4, the yarn thickness, elasticity and other characteristics are dynamically adapted to achieve precise adjustment of the transmission tension and prevent the yarn from breaking or loosening and tangling.

[0038] After tension adjustment, the yarn enters the yarn exit plate 12. The double rodless cylinders 10 at the front end of the base 1 synchronously drive the yarn exit plate 12 to move in a direction perpendicular to the center line of the yarn guide plate 3, i.e., the fabric width direction. During the movement, the yarn is combed, further eliminating yarn twists and wrinkles and improving straightness. The square rod 1101 structure of the bracket 11 and the mounting groove 101 of the base 1 ensure that the yarn exit plate 12 moves stably without deviation, and finally the flat yarn is accurately led out to the subsequent warping process.

[0039] Throughout the process, the quick-release structure of the yarn guide plate 3 can be quickly replaced according to the yarn specifications without affecting the consistency of the yarn guiding path, thus achieving efficient adaptation of multiple yarn specifications.

Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention.
