A weaving mechanism for a webbing machine

Abstract

The application provides a weaving mechanism for a loom, comprising a weaving head, an upper aluminum hand and a lower aluminum hand arranged at the upper and lower ends of the weaving head respectively, a crochet needle installed on the upper aluminum hand for performing a weft insertion action, a steel buckle seat connected to one end of the lower aluminum hand through a pull rod for receiving power input, and an integrated double shaft bearing connected between the upper and lower aluminum hands, which simplifies the overall structure and facilitates installation. The integrated double shaft bearing comprises a double shaft rod member, an integral outer ring sleeved on the double shaft rod member and forming an accommodation gap, and the two ends of the double shaft rod member respectively extend out of the integral outer ring and are rigidly connected with the upper and lower aluminum hands, so as to realize gapless rigid power transmission, reduce the transmission gap of a traditional connecting rod structure, and simultaneously form a stable two-point support structure by sleeving two groups of interval-distributed rolling body components in the integral outer ring, thereby fundamentally ensuring the absolute coaxiality of the two bearing units, effectively avoiding the eccentric load swing of the double shaft rod member, and significantly improving the support rigidity and operation stability.

Description

Technical Field

[0001] This application relates to the field of ribbon weaving machine technology, and more particularly to a weaving mechanism for a ribbon weaving machine. Background Technology

[0002] A ribbon weaving machine is a textile machine used to weave ribbons of various widths and widths. The weft hook oscillation mechanism is one of the core components of the weaving head of a ribbon weaving machine. Its function is to drive the weft hook to oscillate at high speed to complete the weft insertion action. However, the weft hook oscillation mechanism of existing ribbon weaving machines generally adopts a split bearing support structure. The two independent bearings are assembled by being separated by a spacer sleeve. It is difficult to ensure coaxiality during long-term high-speed reciprocating oscillation of the ribbon weaving machine, which will inevitably cause wear and eventually lead to mechanism failure. Frequent replacement of vulnerable parts is required, which increases the processing cost. Utility Model Content

[0003] The purpose of this invention is to provide a weaving mechanism for a ribbon weaving machine to solve the above-mentioned problems.

[0004] The technical solution of this application is implemented as follows: This application provides a weaving mechanism for a ribbon weaving machine, including a weaving head. The upper and lower ends of the weaving head are respectively provided with an upper aluminum hand and a lower aluminum hand. A hook is installed on the upper aluminum hand, and a pull rod is connected to one end of the lower aluminum hand for connecting to a steel buckle seat. An integrated double bearing is connected between the upper aluminum hand and the lower aluminum hand. When the steel buckle seat swings back and forth, it drives the lower aluminum hand to swing. The upper aluminum hand is driven to swing synchronously through the cooperation of the integrated double bearing. The integrated double bearing includes a double shaft member, which is fitted with an integral outer ring and forms an accommodating gap. The two ends of the double shaft member are located outside the integral outer ring and are respectively connected to the upper aluminum handle and the lower aluminum handle. The integral outer ring is fitted with two sets of spaced rolling elements. The two sets of rolling elements are coaxially installed in the receiving gap and are located in the upper and lower spaces of the receiving gap.

[0005] In one embodiment, the inner wall ring of the integral outer ring is provided with two sets of spaced inner wall raceways. Two sets of rolling element components are respectively installed between the inner wall raceway and the double shaft member.

[0006] In one embodiment, end face sealing rings are provided at the joints between both ends of the dual-axis rod and the integral outer ring. Two sets of radial sealing rings are also provided in the accommodating gap. The radial sealing rings are sleeved on the outer periphery of the double shaft member, and the two sets of rolling element components are located at both ends of the radial sealing rings.

[0007] In one embodiment, both the upper aluminum handle and the lower aluminum handle have through holes for the passage of the dual-axis rod, and one side of the through hole is provided with a bolt hole extending to the outside. The bolt hole has a threaded connection to a screw rod. When one end of the dual-axis rod is installed on the upper or lower aluminum handle, the screw rod abuts against part of the dual-axis rod through the threaded connection of the bolt hole.

[0008] In one embodiment, the rolling element component includes a retainer and a plurality of balls. The retainer is sleeved on the outer periphery of the dual-shaft member and located in the receiving gap. The retainer is provided with an outer ring raceway at the position corresponding to the inner wall raceway. Several balls are located between the retainer and the integral outer ring.

[0009] In one embodiment, the outer cylindrical surface of the integral outer ring and the inner cylindrical surface of the mounting hole of the weaving head fixing seat are interference fit.

[0010] In one embodiment, a weaving head is also provided with a strip plate.

[0011] The advantages or beneficial effects of the above technical solutions include at least the following: This application discloses a weaving mechanism for a ribbon weaving machine. The weaving head has an upper aluminum hand for mounting hooks and a lower aluminum hand connected to a steel buckle seat via a pull rod at its upper and lower ends. An integrated double bearing serves as the sole connecting and synchronizing component between the upper and lower aluminum hands. Therefore, when the steel buckle seat reciprocates and drives the lower aluminum hand to swing, the integrated double bearing directly drives the upper aluminum hand to swing synchronously, eliminating the need for an additional linkage synchronizing mechanism. Because the integrated double bearing employs an integral double-axis rod design, with its two ends extending from an integral outer ring and rigidly connected to the upper and lower aluminum hands, it achieves a backlash-free rigid power transmission between the upper and lower aluminum hands. This design completely eliminates the transmission backlash present in traditional linkage synchronization structures, ensuring complete consistency in the swing angle and angular velocity of the upper and lower aluminum hands. Furthermore, because the integrated double bearing adopts a single integral outer ring structure, and two sets of spaced rolling elements are coaxially installed within the accommodating gap formed by the integral outer ring and the double shaft members, a stable two-point support structure is formed. This ensures the absolute coaxiality of the two bearing units, avoids off-center loading and swaying of the double shaft members, and improves the support rigidity and operational stability of the mechanism. This not only extends the service life of the equipment but also reduces the difficulty of assembly and debugging and maintenance costs. Attached Figure Description

[0019] Reference Figures 1-6 A weaving mechanism for a ribbon weaving machine includes a weaving head 1. It is the mounting base of the entire mechanism, and adopts an integrated casting or welding structure to ensure sufficient rigidity and stability. The upper and lower ends of the weaving head 1 are respectively provided with an upper aluminum hand 11 and a lower aluminum hand 12. The upper aluminum hand 11 is equipped with a hook 111. The upper aluminum hand 11 serves as the mounting carrier for the hook 111. Its front end is designed with precise hook 111 mounting holes, which can realize quick replacement and precise positioning of the hook 111. The hook 111 is a key component that directly participates in weaving. The accuracy of its movement trajectory directly determines the quality of the webbing. One end of the lower aluminum hand 12 is connected to a pull rod 121 for connecting to the steel buckle seat. During the swinging process, the weft yarn is beaten up and pressed to the weft end. An integrated double bearing 2 is connected between the upper aluminum hand 11 and the lower aluminum hand 12. When the steel buckle seat swings back and forth, it drives the lower aluminum hand 12 to swing. Through the cooperation of the integrated double bearing 2, the upper aluminum hand 11 is driven to swing synchronously. The integrated double bearing 2 includes a double-shaft member 21, which is fitted with an integral outer ring 22 and forms an accommodating gap. The two ends of the double-shaft member 21 are located outside the integral outer ring 22 and are respectively connected to the upper aluminum hand 11 and the lower aluminum hand 12. The integrated double bearing 2 is the core component of the mechanism. It is made of high-precision seamless steel pipe or integral forging. The two ends extend outside the integral outer ring 22 and are rigidly connected to the upper aluminum hand 11 and the lower aluminum hand 12 by interference fit or bolt connection. The axis of the double-shaft member 21 is completely coincident with the swing axis of the upper aluminum hand 11 and the lower aluminum hand 12, ensuring that the force transmission is eccentric. Compared with the traditional structure in which the upper and lower aluminum hand 12 are respectively connected to two independent bearing inner rings, the integrated double-shaft member 21 eliminates the connection gap between the two inner rings and realizes rigid synchronization of the up and down movement. The integral outer ring 22 is fitted with two sets of spaced rolling elements 23. The two sets of rolling elements 23 are coaxially installed in the receiving gap, located in the upper and lower spaces of the receiving gap. The two sets of rolling elements 23 are coaxially installed in the receiving gap inside the integral outer ring 22, located in the upper and lower spaces respectively, forming two independent support points. The spaced distribution design forms a double-support structure, which not only effectively increases the support span and significantly improves the bearing's anti-overturning moment capability, but also allows the two sets of rolling elements 23 to share the load when the upper and lower aluminum handles 12 swing and generate an overturning moment, avoiding the uneven wear phenomenon that is prone to occur with single-support.

[0020] Based on the above structure, with the weaving head 1 as the basic carrier, the upper aluminum hand 11 with hook needles 111 installed at the upper and lower ends and the lower aluminum hand 12 connected to the steel buckle seat through the pull rod 121 are respectively provided. An integrated double bearing 2 is used as the only connection and synchronous transmission component of the upper and lower aluminum hands. The integrated double bearing 2 uses an integrated double shaft rod 21 as the common inner ring support of the two bearing units. Both ends extend out of the integral outer ring 22 and are rigidly connected to the upper and lower aluminum hands 12. With the integral outer ring 22 which is machined into a single piece, the coaxiality error problem of the assembly of the split bearing outer ring is avoided. At the same time, two sets of rolling element components 23 are installed coaxially at intervals inside the integral outer ring 22, located in the upper and lower spaces of the accommodating gap, forming two independent rotation support points with maximum spacing, ensuring the compactness of the structure and a significant improvement in assembly efficiency, and improving the overall synchronization accuracy. During operation, the main shaft of the weaving machine converts the rotational motion into the linear reciprocating motion of the pull rod 121 through the eccentric wheel mechanism. The pull rod 121 pulls the steel buckle seat to swing back and forth around the axis of the integrated double bearing 2. The steel buckle seat is rigidly connected to the lower aluminum hand 12, which synchronously drives the lower aluminum hand 12 to swing. The steel buckle installed on the steel buckle seat pushes the weft yarn introduced into the weaving point towards the main body of the weaving, completing the weft insertion process. The swing of the lower aluminum hand 12 is directly transmitted to the double shaft rod 21 through its rigid connection with the lower end of the double shaft rod 21, so that the double shaft rod 21 rotates synchronously around its own axis, thereby driving the upper aluminum hand 11 and the hook needle 111 to complete a series of actions such as weft insertion, hooking, and loop release, realizing high-speed continuous production of the weaving.

[0021] In one embodiment, reference is made to Figure 1 , Figure 3 and Figure 6The inner wall ring of the integral outer ring 22 is provided with two sets of spaced inner wall raceways 221. The rolling element components 23 are respectively installed between the inner wall raceways 221 and the double shaft member 21. The inner wall raceways 221 provide a precise running track for the rolling element components 23, restricting the axial movement and radial offset of the rolling element components 23, and avoiding bearing jamming and abnormal noise caused by rolling element misalignment. The two sets of rolling element components 23 run in independent raceways, without interfering with each other, and at the same time jointly support the rotation of the double shaft member 21. This structure integrates the inner and outer raceways of two traditional independent bearings into an integral outer ring 22 and an integral shaft, reducing the coaxiality error between split bearings. Moreover, the machining accuracy of the integral raceway is much higher than the assembly accuracy of two independent bearings, further improving the synchronization accuracy of the upper aluminum handle 11 and the lower aluminum handle 12.

[0022] In one embodiment, reference is made to Figure 1 , Figure 3 and Figure 4 Both ends of the dual-shaft member 21 and the joint of the integral outer ring 22 are provided with end face sealing rings 24. The end face sealing rings 24 serve as the first line of defense to prevent a large amount of fiber dust, yarn fuzz and oil stains present in the production environment of the ribbon machine from entering from the end face gaps at both ends of the bearing. Two sets of spaced radial sealing rings 25 are also provided in the accommodating gap. The radial sealing rings 25 are sleeved on the outer periphery of the double shaft member 21. The two sets of rolling element components 23 are located at both ends of the radial sealing rings 25. The radial sealing rings 25 serve as a second line of defense, further blocking a small amount of tiny contaminants that penetrate the first line of defense, while preventing the leakage of grease inside the bearing. The two sets of rolling element components 23 are completely enclosed in a sealed space formed by the two radial sealing rings 25, the integral outer ring 22, and the double shaft member 21, ensuring a clean lubrication environment and thus improving the overall service life of the integrated double bearing 2.

[0023] In one embodiment, reference is made to Figure 1 , Figure 2 , Figure 4 and Figure 5 Both the upper aluminum handle 11 and the lower aluminum handle 12 have through holes 3 for the dual-axis rod 21 to pass through. One side of the through hole 3 is provided with bolt holes extending to the outside. The through hole 3 can be used to install and position the dual-axis rod 21. The bolt hole threaded connection has a screw member 31. When one end of the dual-axis member 21 is installed on the upper aluminum hand 11 or the lower aluminum hand 12, the screw member 31 abuts against the dual-axis member 21 through the threaded connection of the bolt hole. The friction generated by the axial thrust of the screw firmly connects the dual-axis member 21 to the upper aluminum hand 11 and the lower aluminum hand 12, avoiding the keyway wear and loosening problems that are prone to occur under high-speed reciprocating oscillation of keyed connections, thereby improving the reliability of the connection. This connection method is a detachable rigid connection, which does not require machining keyways or threads on the dual-axis member 21, avoiding stress concentration on the shaft. At the same time, it is easy to install and disassemble. Assembly or replacement can be completed by tightening or loosening the screw. The tightness of the connection can be controlled by adjusting the tightening force of the screw, which is convenient for fine adjustment of the assembly accuracy.

[0024] In one embodiment, reference is made to Figure 1 , Figure 3 and Figure 6 The rolling element component 23 includes a retainer 231 and several balls 232. The retainer 231 is sleeved on the outer periphery of the double shaft member 21 and located in the receiving gap. The retainer 231 is provided with an outer ring raceway 2311 around the position of the inner wall raceway 221. Several balls 232 are located between the retainer 231 and the integral outer ring 22. The retainer 231 separates the balls 232 at equal intervals to prevent them from rubbing and colliding with each other, ensuring that the balls 232 bear the load evenly and run smoothly. The balls 232 make pure rolling motion between two precision-machined raceways, converting sliding friction into rolling friction, reducing power loss and heat generation, thereby reducing frictional resistance and wear, thus enabling them to withstand larger radial loads and a certain axial load, meeting the working conditions of high-speed reciprocating oscillation of the weaving machine.

[0025] In one embodiment, reference is made to Figure 1 , Figure 2 and Figure 4 The outer cylindrical surface of the integral outer ring 22 and the inner cylindrical surface of the mounting hole of the weaving head 1 fixing seat are interference fit. The interference fit generates huge radial pressure between the outer surface of the integral outer ring 22 and the inner surface of the mounting hole, forming a firm static connection. This connection method can effectively prevent the bearing outer ring from rotating or moving under the alternating load generated by high-speed reciprocating oscillation, thus ensuring the stability of the bearing support.

[0026] In one embodiment, reference is made to Figure 1 The weaving head 1 is also equipped with a guide plate 13, which is used to guide the direction of the webbing so that the webbing can be output smoothly and neatly after weaving, preventing the webbing from twisting, tangling or scratching, ensuring the surface quality of the webbing, and reducing downtime accidents caused by webbing tangling.
