Description

Technical Field

[0001] This application relates to the field of ribbon weaving machine technology, and more particularly to a motor-driven annular ribbon weaving device. Background Technology

[0002] A ribbon loom is a textile machine specifically designed for weaving various ribbon-like fabrics. Its core function is to drive the warp feeding, weaving, and take-up mechanisms through a transmission system to work together, allowing the warp and weft yarns to interweave according to a preset pattern. The transmission system is the core component, and gear drive is the mainstream transmission method of traditional ribbon looms. It relies on the meshing of gears to transmit power and ensure the synchronous operation of each mechanism. However, the essence of gear transmission is rigid meshing to transmit power, and gear meshing has natural tooth backlash. After long-term operation, tooth surface wear will further expand the backlash, which can easily lead to large fluctuations in yarn tension. This can cause problems such as skipped stitches, broken yarns, uneven density, rough edges, and misaligned jacquard patterns in the ribbon. In particular, it cannot meet the requirements of high-end precision ribbon weaving, making it impossible to perform high-speed operation and easily causing ribbon quality defects. Summary of the Invention

[0003] The purpose of this invention is to provide a motor-driven annular webbing device to solve the above-mentioned problems.

[0004] The technical solution of this application is implemented as follows:

[0005] This application provides a motor-driven annular webbing device, including a machine base with a receiving cavity. The receiving cavity has an opening extending to the outside of the machine base. Two sets of openings are arranged at intervals. A support base is arranged on the machine base corresponding to the opening. The support base has holes communicating with the opening. Several circumferentially distributed support columns are arranged on the support base. The support columns have base plates. Needle plate seats are placed on the several base plates. Weaving components are installed on the needle plate seats. Two sets of winding mechanisms are arranged at intervals inside the receiving cavity. The two sets of winding mechanisms are respectively located below the two weaving components.

[0006] The weaving component includes a needle cylinder and a drive component. The needle cylinder is located inside the needle plate seat and has a hook on it. The bottom of the needle cylinder has a needle cylinder seat. The drive component is located inside the accommodating cavity and includes a machine housing. The machine housing is installed inside the machine base. A drive motor is installed on one side of the machine housing. A stator is provided inside the machine housing. A rotor is rotatably provided on the inner ring of the stator. The needle cylinder seat is installed on the rotor. The needle cylinder is rotated circumferentially by the rotor.

[0007] Several evenly distributed triangular seats are mounted on the supporting chassis, and the syringe is located between the triangular seats;

[0008] The winding mechanism includes a fabric roll support, a drive turntable is installed at the bottom of the fabric roll support, a gear transmission mechanism is installed inside the fabric roll support, and the gear transmission mechanism is connected to the winding roller and located inside the fabric roll support.

[0009] The gear transmission mechanism is also connected to two sets of spaced-apart traction rollers, forming a webbing flow area between the two sets of traction rollers, with the traction rollers located above the take-up roller.

[0010] The fabric roll support also has two sets of spaced limiting rods located above the pull roller;

[0011] A tensioning component is movably mounted on the limiting rod. The tensioning component includes a connecting seat with a through hole and is fitted onto the limiting rod, allowing the connecting seat to rotate around the limiting rod. One end of the connecting seat is provided with a protruding part with an opening. A roller is mounted inside the opening via a shaft. The roller is located on the outer periphery of the protruding part. When the fabric belt is in the flow area, the roller abuts against the fabric belt.

[0012] Several tensioning components are provided and distributed at intervals along the length of the limiting rod.

[0013] Furthermore, the machine platform is equipped with columns around its perimeter, and several columns are connected to support bases. Yarn feeding components are installed on the support bases. The yarn feeding components include supports, and several supports are arranged circumferentially on the support bases. Support rods are installed on the supports, and placement seats are provided on the support rods. Several placement seats form a receiving area for the yarn feeding frame.

[0014] Several yarn feeders are spaced apart on the yarn feeding frame;

[0015] The support is provided with several slots, which are spaced apart along the length of the support. When several support members are installed in different slots, the range of the receiving area expands or shrinks.

[0016] Furthermore, a limiting plate is provided on the support column. When the needle plate seat is located on the base plate, the limiting plate is located above the base plate. A threaded hole is provided through the limiting plate, and a limiting component is movably installed on the threaded hole. The limiting component includes a screw rod, which is threadedly connected to the threaded hole.

[0017] A pad is installed at one end of the screw facing the limiting plate, and a handwheel is installed at the other end. When the needle plate seat is located on the base plate, the rotation of the screw in the threaded hole causes the pad to abut against or move away from the top of the needle plate seat.

[0018] Furthermore, the top circumference of the needle plate holder is provided with several brackets, on which mounting plates are placed and located above the needle cylinder. Several yarn guides are provided on the side of the mounting plate facing the needle cylinder and distributed along the circumference of the mounting plate.

[0019] Furthermore, the connecting seat has a groove, and a portion of the protruding extension is movable within the groove. Through the relative movement of the protruding extension within the groove, the roller moves closer to or further away from the connecting seat.

[0020] Furthermore, the placement seat has a slot, and when the yarn supply frame is installed on the placement seat, part of the yarn supply frame is embedded in the slot.

[0021] Furthermore, the slot is provided with a threaded groove, and the outer periphery of the support member is provided with a threaded protrusion that matches the threaded groove. Through the cooperation of the threaded protrusion and the threaded groove, the support member is threadedly connected to the slot.

[0022] The advantages or beneficial effects of the above technical solutions include at least the following:

[0023] This application discloses a motor-driven annular weaving device. Based on a machine base, the accommodating cavity provides a closed installation space. Two sets of spaced openings connect to the holes in the supporting chassis, and a circumferential support column and base plate stably support the needle plate seat. Simultaneously, the weaving component mounted on it has two sets of winding mechanisms below, forming a dual-path parallel weaving unit, enabling simultaneous weaving operations at two stations. Since the needle cylinder used for weaving in the weaving component is mounted on the driving component, the drive motor in the driving component, through the linkage between the stator and rotor within the machine housing, directly drives the needle cylinder seat to rotate circumferentially. This results in a short transmission link, low loss, and precise control of the needle cylinder speed and angle, ensuring stable hook trajectory and avoiding transmission delay and accuracy degradation issues in gear transmission. At the same time, evenly distributed triangular seats on the supporting chassis surround and limit the needle cylinder, restricting radial displacement and ensuring coaxial rotation. This disperses the operating force and reduces component wear. By using the driving component to drive the needle cylinder to rotate, this method solves the problem that existing weaving machines cannot operate at high speeds, easily leading to weaving quality defects.

[0047] Reference Figures 1-6A motor-driven annular webbing device includes a machine base 1 with a receiving cavity 11. The receiving cavity 11 has openings 12 extending to the outside of the machine base 1, and the openings 12 are arranged in two sets at intervals. A supporting base 2 is provided on the machine base 1 corresponding to the positions of the openings 12. The supporting base 2 has holes communicating with the openings 12. Several circumferentially distributed support stands 21 are provided on the supporting base 2, and each support stand 21 has a base plate 211 on which needles are placed. The base 3 and needle plate base 3 are equipped with weaving components 4. The cavity 11 is provided with two sets of spaced winding mechanisms 5. The two sets of winding mechanisms 5 are located below the two weaving components 4 respectively. The machine base 1 is supported as a whole. The built-in cavity 11 is used to hide the drive component 42 and the winding mechanism 5, reduce space occupation and protect the core transmission components. The opening 12 provided in the cavity 11 is the channel for the webbing to fall from the weaving layer to the winding layer. The setting of the two sets of openings 12 can realize the simultaneous operation of two stations.

[0048] The weaving component 4 includes a needle cylinder 41 and a drive component 42. The drive component 42 adopts a hollow torque motor as used in the prior art. Its core feature is that the center of the motor rotor or stator is designed with a through-hole hollow hole. When the rotor rotates, the stator can remain stationary. At the same time, it retains the essential attributes of a torque motor, such as low speed, high torque, and direct drive without a reducer. The specific connection method is well known to those skilled in the art, so it will not be described in detail in this application. The needle cylinder 41 is located in the needle plate seat 3. The needle cylinder 41 has a hook 411 and a needle cylinder seat 412 at the bottom. The drive component 42 is located in the accommodating cavity 11 and includes a housing. 421. The housing 421 is installed inside the machine base 1. A drive motor 422 is installed on one side of the housing 421. A stator 423 is provided inside the housing 421. A rotor 424 is rotatably provided on the inner ring of the stator 423. The syringe holder 412 is installed on the rotor 424. The syringe 41 rotates in a circular motion through the rotor 424. After the drive motor 422 starts, it drives the rotor 424 inside the housing 421 to rotate at high speed and stably. Because the syringe holder 412 and the rotor 424 are rigidly connected, the rotor 424 directly links the syringe holder 412 and the syringe 41 to perform circular motion synchronously. The high coaxiality during the rotation lays the foundation for uniform knitting.

[0049] Several evenly distributed triangular seats 22 are installed on the supporting chassis 2. The cylinder 41 is located between the triangular seats 22. When the cylinder 41 rotates in a circle, the hook 411 on the surface moves synchronously with the cylinder 41. The hook 411 will continuously pass through the triangular seats 22 arranged around it. The contour trajectory of the triangular seats 22 provides precise guidance for the hook 411, and the yarn is continuously woven into a ring-shaped blank strip.

[0050] Based on the above structure, with the machine base 1 as the supporting foundation, the drive component 42 and the winding mechanism 5 are built into the accommodating cavity 11, and together with the supporting chassis 2, support stand 21, needle plate seat 3 and weaving component 4 at the corresponding positions of the external opening 12, an integrated architecture for weaving and winding is formed. During the weaving operation, the drive motor 422 drives the rotor part 424 inside the machine housing 421 to rotate. The rotor part 424, in conjunction with the needle cylinder seat 412 and the needle cylinder 41, performs a circular motion. As the needle cylinder 41 rotates with the needle cylinder 41, the hooks 411 on the needle cylinder 41 are guided by the circumferentially distributed triangular seats 22. The process involves hooking, looping, and weaving the yarn to form a circular webbing blank. With the cooperation of the drive component 42, a rapid rotational response can be achieved, avoiding the sluggish weaving process caused by the traditional motor drive. The woven webbing falls through the opening 12 and the holes of the supporting base 2 to the lower winding mechanism 5, which pulls and winds it up, realizing the continuous forming and collection of the circular webbing. This solves the problem that the existing weaving component 4 requires gears for step-by-step transmission, which causes a delay in transmission response and affects weaving efficiency and speed.

[0051] In one embodiment, reference is made to Figure 1 , Figure 2 , Figure 4 and Figure 8 The machine base 1 is also provided with columns 13 around its perimeter. Several columns 13 are connected to support bases 131. A yarn feeding component 6 is installed on the support base 131. The yarn feeding component 6 includes a support 61. Several supports 61 are provided and distributed circumferentially on the support base 131. Support rods 62 are installed on the support 61. Placement seats 621 are provided on the support rods 62. Placement seats 621 have slots 6211. Several placement seats 621 form a receiving area for the yarn feeding frame.

[0052] The yarn feeder has several yarn feeders spaced apart. The support 61 has several slots 611 spaced apart along the length of the support 61. When several support rods 62 are installed in different slots 611, the accommodating area expands or shrinks. The yarn feeder is placed in the accommodating area formed by multiple placement seats 621. The yarn feeders output yarn at intervals, accurately supplying the lower tube 41 hook 411 to meet the yarn requirements of the loop webbing. When the support rods 62 are installed in different slots 611, the distribution spacing of the placement seats 621 can be changed, thereby expanding or shrinking the accommodating area. It can adapt to multiple specifications of yarn feeders, solving the problem of insufficient adaptability of a single yarn feeder. It is compatible with the needs of different yarn types and different weaving volumes. At the same time, the circumferentially distributed support 61 and placement seats 621 make the yarn feeder evenly stressed. The spaced distribution of the yarn feeders makes the yarn output orderly, reduces yarn tangling, and achieves stable yarn feeding operation.

[0053] In one embodiment, reference is made to Figure 1 , Figure 2 , Figure 4 and Figure 6 The winding mechanism 5 includes a fabric roll support 51, a drive turntable 52 is installed at the bottom of the fabric roll support 51, and a gear transmission mechanism is installed inside the fabric roll support 51. The gear transmission mechanism adopts the multi-gear drive method in the prior art. The rotation method of the winding roller 53 and the pull roller 54 in the winding mechanism 5 is well known to those skilled in the art, so it will not be described in detail in this application. The gear transmission mechanism is connected to the winding roller 53 and is located inside the fabric roll support 51.

[0054] The gear transmission mechanism is also connected to two sets of spaced-apart traction rollers 54, forming a flow area for the webbing between the two sets of traction rollers 54. The traction rollers 54 are located above the take-up roller 53. The woven annular webbing falls into the flow area between the traction rollers 54. The two sets of traction rollers 54 are driven to rotate synchronously by the gear transmission mechanism to pull the webbing at a uniform speed, keeping the webbing taut and preventing it from loosening and deforming after weaving. The pulled and shaped webbing is then conveyed to the lower take-up roller 53. The take-up roller 53 is driven to rotate by the gear transmission mechanism to complete the orderly take-up of the webbing. By pulling before taking up, the traction rollers 54 are pulled and tensioned in advance to eliminate wrinkles generated during the webbing weaving process, making the webbing pattern flat and the width uniform. This prevents the webbing from stacking or skewing during take-up, and the webbing roll diameter is uniform after take-up, which is convenient for subsequent storage and processing.

[0055] In one embodiment, reference is made to Figure 1 , Figure 2 , Figure 4 and Figure 9 A limiting plate 212 is provided on the support stand 21. When the needle plate seat 3 is located on the base plate 211, the limiting plate 212 is located above the base plate 211. A threaded hole 2121 is provided through the limiting plate 212. A limiting component 7 is movably installed on the threaded hole 2121. The limiting component 7 includes a screw 71, which is threadedly connected to the threaded hole 2121. The thread on the screw 71 matches the threaded hole 2121 on the limiting plate 212.

[0056] A pad 72 is installed at one end of the screw 71 facing the limiting plate 212. The pad 72 can be made of rubber or silicone material as in the prior art. A handwheel 73 is installed at the other end. When the needle plate seat 3 is on the base plate 211, the rotation of the screw 71 in the threaded hole 2121 causes the pad 72 to abut or move away from the top of the needle plate seat 3. After the needle plate seat 3 is placed on the base plate 211, the handwheel 73 is rotated to drive the screw 71 to screw in or out in the threaded hole 2121, causing the pad 72 to move downward and abut against the top of the needle plate seat 3. This forms a two-way fixation of the base plate 211 support and the pad 72 pressing down in the limiting plate 212. This avoids the needle cylinder 41 rotating at high speed with the rotor 424 during the weaving process, which can cause slight movement of the needle plate seat 3. By pressing, the vertical displacement of the needle plate seat 3 is restricted, and the coaxiality of the rotation of the needle cylinder 41 is indirectly ensured.

[0057] In one embodiment, reference is made to Figure 1 , Figure 2 , Figure 4 , Figure 6 and Figure 7 The fabric roll support 51 also has two sets of spaced-apart limiting rods 55 located above the pull roller 54. The limiting rods 55 can be used to prevent the webbing from shifting position. A tensioning component 8 is movably mounted on the limiting rod 55. The tensioning component 8 is used to adjust the tension of the webbing. The tensioning component 8 includes a connecting seat 81, which has a through hole and is fitted onto the limiting rod 55, allowing the connecting seat 81 to rotate around the limiting rod 55. One end of the connecting seat 81 is provided with a protruding extension 82, which has an opening. A roller 821 is mounted in the opening via a shaft. Part of the roller 821 is located on the outer periphery of the protruding extension 82. When the fabric is in the flow area, the roller 821... Part 21 abuts against the webbing. Before the webbing falls to the pull roller 54 after weaving, it first contacts the roller 821 on the limit rod 55. The connecting seat 81 can rotate freely around the limit rod 55. The roller 821 rotates synchronously with the movement of the webbing, reducing wear on the surface of the webbing. With the setting of the tensioning component 8, when the webbing is slack, the connecting seat 81 can naturally droop under the action of gravity or the tension of the webbing. The roller 821 increases the pressure on the webbing and automatically tensions the webbing. When the tension of the webbing is too high, the connecting seat 81 rotates upward and the pressure of the roller 821 decreases, preventing the webbing from being pulled apart. The rolling contact of the roller 821 replaces the sliding friction, preventing the surface of the webbing from getting fuzzy or scratched, and ensuring the appearance and strength of the finished webbing.

[0058] Several tensioning components 8 are provided and are spaced apart along the length of the limiting rod 55, so that the force is evenly distributed in the width direction of the webbing and avoids local slack or over-tightness.

[0059] In one embodiment, reference is made to Figure 1 , Figure 2 and Figure 5 The top circumference of the needle plate has several brackets 31, on which a mounting plate 32 is placed and located above the needle cylinder 41. On the side of the mounting plate 32 facing the needle cylinder 41, several yarn guides 321 are arranged along the circumference of the mounting plate 32. The yarn output from the yarn feeder is first guided by the yarn guides 321 on the mounting plate 32. The yarn guides 321 are distributed along the circumference of the mounting plate 32 and match the circumferential rotation trajectory of the needle cylinder 41, so that the yarn is accurately delivered to the corresponding hook 411 on the needle cylinder 41. At the same time, the yarn guides 321 can comb the yarn to avoid multiple strands of yarn from tangling, and control the yarn delivery angle so that the hook 411 can smoothly hook the yarn, improving the stability of loop knitting. The yarn is directionally guided by the yarn guides 321 and directly reaches the working position of the hook 411, reducing the probability of missed stitches and wrong stitches, thereby improving weaving efficiency.

[0060] In one embodiment, reference is made to Figure 1 , Figure 2 , Figure 6 and Figure 7 The connecting seat 81 has a groove 811, and part of the protruding extension 82 is movable within the groove 811. Through the relative movement of the protruding extension 82 within the groove 811, the roller 821 moves closer to or further away from the connecting seat 81. According to the thickness, width, and material hardness of the webbing, the position of the protruding extension 82 within the groove 811 is moved to adjust the distance between the roller 821 and the connecting seat 81, thereby changing the tension of the roller 821 on the webbing. This adapts to the tension requirements of webbing of different specifications and materials, ensuring tension and wrinkle prevention while avoiding damage or breakage of the webbing. This solves the problem of insufficient adaptability of single tension force and expands the weaving range of the equipment.

[0061] In one embodiment, reference is made to Figure 1 , Figure 2 and Figure 8 The placement base 621 has a slot 6211. When the yarn supply frame is installed on the placement base 621, part of the yarn supply frame is embedded in the slot 6211. When the yarn supply frame is placed on the placement base 621, the bottom or side part is embedded in the slot 6211. The slot forms a lateral limit on the yarn supply frame. Combined with the limiting function of the original slot 6211, the yarn supply frame is fixed in both the lateral and longitudinal directions. This avoids the displacement of the yarn supply frame due to equipment vibration during weaving, reduces yarn tension fluctuations caused by the displacement of the yarn supply frame, reduces the probability of yarn breakage and skipped threads, and enhances stability. In addition, the slot 6211 can be used as the installation positioning reference for the yarn supply frame, which can quickly complete the placement of the yarn supply frame and improve the efficiency of changing frames and yarn.

[0062] In one embodiment, reference is made to Figure 1 , Figure 2 and Figure 3A control box is installed inside the machine base 1. A door 14 is hinged to the machine base 1. Heat dissipation vents are evenly distributed on the door 14. The heat dissipation vents allow the inside of the machine base 1 to communicate with the outside. The control box integrates the equipment control elements to provide control signals to components such as the drive motor 422 and the winding mechanism 5. The equipment control elements can be PLC controllers in the existing technology to coordinate the synchronous operation of various components. At the same time, when the equipment is running, the control elements will generate heat. The heat dissipation vents of the door 14 allow air convection inside and outside the machine base 1 to dissipate the heat inside the machine base 1 and prevent the control elements from aging due to high temperature.

[0063] In one embodiment, reference is made to Figure 1 , Figure 2 and Figure 8 The slot 611 is provided with a threaded groove 6111, and the outer periphery of the support rod 62 is provided with a threaded protrusion 622 that matches the threaded groove 6111. Through the cooperation of the threaded protrusion 622 and the threaded groove 6111, the support rod 62 is threadedly connected to the slot 611. The self-locking characteristic is achieved through the thread engagement, thereby solving the problem that the snap-fit ​​support rod 62 is prone to loosening and displacement due to equipment vibration, reducing the shaking of the yarn supply frame during conveying, avoiding defects such as yarn breakage, skipped stitches, and disordered webbing patterns caused by yarn supply deviation, and ensuring the quality of the finished ring webbing.
