Description

Technical Field

[0001] This utility model relates to the field of collective doffing technology for spinning machines, specifically a herringbone-shaped collective doffing arm mounting base in the form of a split. Background Technology

[0002] The ring spinning machine is a highly efficient and automated textile equipment that can significantly reduce the labor intensity of workers and improve labor productivity. The collective doffing device can automatically remove all full bobbins from the ring spinning machine and replace them with empty bobbins, completing a series of actions such as yarn pulling, bobbin insertion, and bobbin feeding. The herringbone arm of the collective doffing device is a key component for achieving efficient and automated doffing. The herringbone arm mounting seat is fixed by fitting into the transmission rod and is connected to the long arm of the herringbone arm. In the existing technology, the collective doffing herringbone arm mounting seat is fastened to the transmission rod by a single screw at the bottom, which is difficult to withstand the bidirectional load of pressing and pulling the bobbin during the collective doffing process. This makes the herringbone arm mounting seat prone to movement, affecting the consistency of the collective doffing height, and consequently affecting the collective bobbin insertion and removal rate. Furthermore, after the mounting seat is worn or cracked, it is necessary to disassemble the transmission rod joint for scratching and replacement, resulting in low equipment maintenance efficiency. Summary of the Invention

[0003] To address the shortcomings of existing technologies, this utility model provides a half-type herringbone arm mounting base for collective doffing. This solves the problems of existing technologies where the herringbone arm mounting base for collective doffing is fastened to the transmission rod by a single screw at the bottom, which is insufficient to withstand the bidirectional load during the pressing and pulling of the tube in collective doffing. This makes the herringbone arm mounting base prone to movement, affecting the consistency of the collective doffing height and consequently the collective tube insertion and removal rate. Furthermore, the mounting base needs to be disassembled and the transmission rod joint needs to be scratched out for replacement after wear or cracking, resulting in low equipment maintenance efficiency.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a herringbone arm mounting base in the form of a split-type collective yarn doffing arm, comprising an upper mounting base, a lower mounting base at the bottom of the upper mounting base, arc-shaped protrusions at the top of the upper mounting base and the bottom of the lower mounting base, an arc-shaped groove on the side of the upper and lower mounting bases that are close to each other, a transmission rod connected to the inner wall of the arc-shaped groove, a transmission arm rotatably connected to the top of the upper mounting base, fixing holes equidistantly opened on both sides of the arc-shaped protrusions of the upper mounting base, threaded holes equidistantly opened on both sides of the arc-shaped groove of the lower mounting base, and hexagon socket head cap screws inserted into the inner wall of the fixing holes, the hexagon socket head cap screws being threadedly connected to the threaded holes.

[0005] Preferably, the top of the upper mounting base is provided with connecting plates on both sides of the arc-shaped protrusion, and the connecting plates are provided with mounting holes. The transmission arm is provided with shafts on both sides of one end near the upper mounting base, and the outer wall of the shaft is rotatably connected to a bushing. The bushing is rotatably connected to the mounting hole. The connecting plate is provided with an inner groove on the side near the transmission arm, and a nylon gasket is provided inside the inner groove. The nylon gasket is rotatably connected to the transmission arm.

[0006] Preferably, the bottom two sides of the connecting plate are provided with reinforcing connectors, and the two reinforcing connectors are respectively fixedly connected to the upper mounting base and the arc-shaped protrusion. The two sides of the connecting plate are provided with circular protrusions on the outer side of the mounting hole.

[0007] Preferably, the inner wall of the arc-shaped groove is provided with anti-slip textures at equal intervals.

[0008] Preferably, both sides of the outer wall of the upper and lower mounting bases are provided with arc angles.

[0009] This utility model provides a split-type herringbone arm mounting bracket for collective doffing. It offers the following advantages: This split-type herringbone arm mounting bracket, through the cooperation of an upper mounting base, a lower mounting base, an arc-shaped protrusion, an arc-shaped groove, a transmission rod, a transmission arm, a fixing hole, a threaded hole, and internal hexagonal bolts, divides the herringbone arm mounting bracket into an upper and lower mounting base. Four internal hexagonal bolts securely clamp and fix the transmission rod to the upper and lower mounting bases, preventing displacement or shaking of the herringbone arm mounting bracket during collective doffing operations. This effectively enhances the connection stability between the herringbone arm mounting bracket and the transmission rod, thereby ensuring the consistency of the collective doffing height. Furthermore, when the mounting bracket needs to be replaced, it can be removed from the transmission rod by rotating the internal hexagonal bolts without disassembling the transmission rod, improving the convenience of disassembly and replacement. This contributes to improving the stability and ease of installation and removal of the herringbone arm mounting bracket.

[0010] By cooperating with the upper mounting base, drive arm, connecting plate, mounting hole, shaft, and bushing, the connecting hole of the drive arm is aligned with the mounting hole, the bushing and shaft are inserted in sequence, and the shaft is fixed to connect the drive arm and the mounting base. During the A-arm drive process, the mounting base can support the A-arm and ensure the smooth and stable rotation of the A-arm, while greatly reducing friction and wear during operation. This can further improve the stability and durability of the A-arm connection structure. Attached Figure Description

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] In the existing technology, the herringbone arm mounting base for collective doffing is fastened to the transmission rod by a single screw at the bottom. This is difficult to withstand the bidirectional load during the pressing and pulling of the tube in the collective doffing process. This makes the herringbone arm mounting base prone to movement, which affects the consistency of the collective doffing height and consequently the collective tube insertion and removal rate. Furthermore, after the mounting base is worn or cracked, it is necessary to disassemble the transmission rod joint for scratching and replacement, resulting in low equipment maintenance efficiency.

[0019] In view of this, the present invention provides a split-type herringbone arm mounting base for collective doffing. Through the cooperation of an upper mounting base, a lower mounting base, an arc-shaped protrusion, an arc-shaped groove, a transmission rod, a transmission arm, a fixing hole, a threaded hole, and hexagon socket head cap screws, the herringbone arm mounting base adopts a split-type design, consisting of an upper mounting base and a lower mounting base. Four hexagon socket head cap screws securely clamp and fix the transmission rod to the upper and lower mounting bases, preventing displacement or shaking of the herringbone arm mounting base during collective doffing operations. This effectively enhances the connection stability between the herringbone arm mounting base and the transmission rod, thereby ensuring the consistency of the collective doffing height. Furthermore, when the mounting base needs to be replaced, the upper and lower mounting bases can be separated by rotating the hexagon socket head cap screws, allowing the herringbone arm mounting base to be removed from the transmission rod without disassembling the transmission rod, thus improving the convenience of disassembly and replacement of the herringbone arm mounting base.

[0020] Those skilled in the art should connect all electrical components and their compatible power supplies in this case via wires. Appropriate controllers and encoders should be selected according to the actual situation to meet control requirements. The specific connection and control sequence should refer to the working principle described below, where the electrical components are connected in sequence. The detailed connection methods are well-known in the art. The following mainly introduces the working principle and process, and will not describe the electrical control further.

[0021] Depend on Figure 1-5 It is known that a type of chevron-shaped collective yarn-winding herringbone arm mounting base includes an upper mounting base 1, a lower mounting base 2 at the bottom of the upper mounting base 1, arc-shaped protrusions 3 at the top of the upper mounting base 1 and the bottom of the lower mounting base 2, an arc-shaped groove 4 on the side of the upper mounting base 1 and the lower mounting base 2 that are close to each other, a transmission rod 5 connected to the inner wall of the arc-shaped groove 4, a transmission arm 6 rotatably connected to the top of the upper mounting base 1, fixing holes 7 equidistantly opened on both sides of the arc-shaped protrusion 3 on the upper mounting base 1, threaded holes 8 equidistantly opened on both sides of the arc-shaped groove 4 on the lower mounting base 2, and hexagonal socket bolts 9 inserted into the inner wall of the fixing holes 7, the hexagonal socket bolts 9 being threadedly connected to the threaded holes 8;

[0022] In the specific implementation process, it is worth noting that the herringbone arm mounting base is divided into upper mounting base 1 and lower mounting base 2 using a half-type configuration through the cooperation between the upper mounting base 1, lower mounting base 2, arc-shaped protrusion 3, arc-shaped groove 4, fixing hole 7, threaded hole 8, and internal hex bolt 9. The upper mounting base 1 and lower mounting base 2 are fixed by inserting the internal hex bolt 9 into the fixing hole 7 and tightening it in the threaded hole 8, thus forming the overall structure of the herringbone arm mounting base. Through the cooperation between the upper mounting base 1 and the transmission arm 6, the transmission arm 6, being the long arm structure of the herringbone arm, connects to the doffing lifting frame at the end furthest from the upper mounting base 1, and the middle of the transmission arm 6 is connected to... The short arm of the A-frame arm forms the A-frame support structure. The upper mounting base 1 is connected to the long arm of the A-frame arm via a shaft structure, which ensures smooth rotation and stable support of the A-frame arm. Through the cooperation between the upper mounting base 1, lower mounting base 2, arc-shaped protrusion 3, arc-shaped groove 4, transmission rod 5, fixing hole 7, threaded hole 8, and hexagon socket head cap screws 9, the upper mounting base 1 and lower mounting base 2 clamp the transmission rod 5 through the arc-shaped groove 4. By inserting four hexagon socket head cap screws 9 into the fixing hole 7 and screwing them into the threaded hole 8 of the lower mounting base 2 for tightening, the upper mounting base 1 and lower mounting base 2 securely clamp and fix the transmission rod 5, improving the connection between the A-frame arm mounting base and the transmission rod. The connection stability between components 5 prevents displacement or shaking of the herringbone arm mounting base during collective doffing operations, ensuring effective force transmission and thus guaranteeing consistent doffing height. Furthermore, when the mounting base needs replacement due to wear or cracking, the herringbone arm mounting base can be separated from the transmission rod 5 by rotating the hexagon socket head cap screw 9, eliminating the need to disassemble the transmission rod 5 and improving the ease of disassembly and replacement. The connection stability between the upper mounting base 1, lower mounting base 2, arc-shaped protrusion 3, arc-shaped groove 4, transmission rod 5, transmission arm 6, fixing hole 7, threaded hole 8, and hexagon socket head cap screw 9 ensures the stability of the herringbone arm mounting base. The herringbone arm mounting base adopts a split design, consisting of an upper mounting base 1 and a lower mounting base 2. Four hexagon socket bolts 9 securely clamp and fix the upper mounting base 1 and lower mounting base 2 to the transmission rod 5, preventing displacement or shaking of the herringbone arm mounting base during collective doffing operations. This effectively enhances the connection stability between the herringbone arm mounting base and the transmission rod 5, ensuring the consistency of the collective doffing height. Furthermore, when the mounting base needs replacement, rotating the hexagon socket bolts 9 separates the upper mounting base 1 and lower mounting base 2, allowing the herringbone arm mounting base to be removed from the transmission rod 5 without disassembling the transmission rod 5, thus improving the convenience of disassembly and replacement of the herringbone arm mounting base.

[0023] Furthermore, the top of the upper mounting base 1 is provided with connecting plates 10 on both sides of the arc-shaped protrusion 3. The connecting plates 10 are provided with mounting holes 11. The transmission arm 6 is provided with shafts 12 on both sides near the upper mounting base 1. The outer wall of the shaft 12 is rotatably connected to the bushing 13. The bushing 13 is rotatably connected to the mounting hole 11. The connecting plate 10 is provided with an inner groove 14 on the side near the transmission arm 6. The inner groove 14 is provided with a nylon gasket 15. The nylon gasket 15 is rotatably connected to the transmission arm 6.

[0024] In the specific implementation process, it is worth noting that, through the cooperation between the upper mounting base 1, the connecting plate 10, and the mounting hole 11, the connecting plate 10 is set on both sides of the top of the upper mounting base 1, and the mounting hole 11 is opened inside the connecting plate 10, forming the connection structure of the upper mounting base 1 for connection with the transmission arm 6. Through the cooperation between the transmission arm 6, the shaft 12, and the bushing 13, the bushing 13 is inserted into the outside of the shaft 12, and the shaft 12 is inserted into the connection hole of the transmission arm 6, forming the connection structure of the transmission arm 6. Through the cooperation between the upper mounting base 1, the transmission arm 6, the connecting plate 10, the mounting hole 11, the shaft 12, and the bushing 13, the connection hole of the transmission arm 6 is aligned with the mounting hole 11, the bushing 13 and the shaft 12 are inserted in sequence, and the shaft 12 is fixed, realizing the connection between the transmission arm 6 and the mounting base. During the transmission of the A-arm, the mounting base provides support for the A-arm, ensuring the smooth and stable rotation of the A-arm, greatly reducing friction and wear during operation, and further improving the stability and durability of the A-arm connection structure.

[0025] Furthermore, both sides of the bottom of the connecting plate 10 are provided with reinforcing connectors 16. The two reinforcing connectors 16 are fixedly connected to the upper mounting base 1 and the arc-shaped protrusion 3 respectively. Circular protrusions 19 are provided on both sides of the connecting plate 10 outside the mounting hole 11.

[0026] In the specific implementation process, it is worth noting that the cooperation between the upper mounting base 1, the arc-shaped protrusion 3, the connecting plate 10 and the reinforcing connector 16 improves the structural stability between the connecting plate 10 and the upper mounting base 1 and the arc-shaped protrusion 3, so that the entire structure can better disperse stress when facing external impact or long-term load, thereby significantly improving the overall durability and safety. The cooperation between the connecting plate 10 and the circular protrusion 19, and the thickening of the outer side of the connecting plate 10 located in the mounting hole 11, enhances the structural strength of the connecting plate 10 and improves the stability and durability of the overall structure.

[0027] Furthermore, the inner wall of the arc-shaped groove 4 is provided with anti-slip textures 17 at equal intervals;

[0028] In the specific implementation process, it is worth noting that through the cooperation between the upper mounting base 1, the lower mounting base 2, the arc groove 4, the transmission rod 5 and the anti-slip texture 17, the friction between the arc groove 4 and the transmission rod 5 is increased by opening the anti-slip texture 17 on the inner side of the arc groove 4, thereby further improving the connection stability between the herringbone arm mounting base and the transmission rod 5.

[0029] Furthermore, both sides of the outer walls of the upper mounting base 1 and the lower mounting base 2 are provided with arc angles of 18°.

[0030] In the specific implementation process, it is worth noting that by setting arc corners 18 at the four corners of the upper mounting base 1 and the lower mounting base 2, the risk of scratches caused by sharp edges and corners during the assembly or disassembly of the mounting base is effectively reduced, thus protecting the safety of the operators.
