The central housing contains a front drive group and a rear drive group that are horizontally opposed to each other, forming the core double-horizontal opposed crankshaft drive mechanism. The front drive group and the rear drive group drive the frame opening mechanism. The drive motor placed in the lower machine base is the power source, which can lower the center of gravity and improve the stability of the whole machine.

The connecting rod gate knife is located between the two sets of push-pull gate knives to form a double-horizontal opposition, which drives the frame component to perform the opening operation, realizing precise zoned coordinated transmission and improving the efficiency and regularity of the ribbon during high-speed operation.

Description

Technical Field

[0001] This application relates to the field of ribbon weaving machine technology, and more particularly to a double horizontal opposed crankshaft driven ribbon weaving machine. Background Technology

[0002] The weaving mechanism of a ribbon loom is a textile machine used to process yarns into various types of ribbons through warp and weft interlacing and weaving processes. Its core function is to precisely control the shedding, weft insertion, and weft beat-up actions. Its structural stability directly determines the density uniformity and dimensional accuracy of the ribbon. However, due to the simple local structural design, existing ribbon looms are prone to vibration during high-speed operation, and the vibration will be amplified as the rotation speed increases. Since the weaving accuracy of the ribbon depends on the synchronization of each mechanism, the positioning accuracy, and the tension stability of the yarn, vibration will directly disrupt this balance and directly lead to a decline in the quality of the ribbon product.

[0028] This application discloses a double-horizontal opposed crankshaft driven ribbon weaving machine. Through a layered layout of a lower machine base, a central housing, a weaving mechanism, and a ribbon take-up mechanism, the machine achieves a modular arrangement. The double-horizontal opposed crankshafts formed by the front and rear double crankshaft groups enable precise, zoned power output, reducing the load pressure of a single drive group while ensuring consistency in front and rear movements. Since the hem frame opening mechanism consists of a push-pull cutter component, a connecting rod cutter component, and a hem frame component, and the front and rear double crankshaft groups drive both the push-pull and connecting rod cutter components, with the connecting rod cutter component located between the two sets of push-pull cutter components, the combination of the two cutters forms a complementary drive. This enables multi-angle, stable opening of the hem frame, allowing for simultaneous opening of multiple hem frames, improving ribbon weaving production efficiency, and solving the problem of existing ribbon weaving machines having simple layouts that are prone to wobbling during high-speed weaving, affecting product quality and machine lifespan.

[0055] Reference Figures 1-7A dual-horizontal opposed crankshaft driven ribbon weaving machine includes a lower frame 1, a frame 11 mounted on one side of the lower frame 1, a central housing 2 connected to the lower frame 1 and mounted on it, and a crankshaft drive mechanism connected to the crankshaft drive mechanism. A hem frame shedding mechanism 5 is also mounted above the central housing 2. A weaving mechanism 6 and a ribbon take-up mechanism 7 are also mounted above the central housing 2. The weaving mechanism 6 is located between the hem frame shedding mechanism 5 and the ribbon take-up mechanism 7. This modular design, with the lower frame 1, central housing 2, and other components installed separately, avoids equipment swaying and shifting during high-speed weaving. Simultaneously, the weaving mechanism 6 is positioned between the shedding mechanism and the take-up mechanism, closely aligning with the core ribbon weaving process of shedding, weaving, and take-up, reducing tension loss in the ribbon transmission path. To mitigate the risks of wear and offset, the brown frame opening mechanism 5 includes a push-pull shut-off component 51 and a connecting rod shut-off component 52. The central housing 2 includes a front housing 21 and a rear housing 22 that are interconnected. The crankshaft drive mechanism includes a front drive group 3 and a rear drive group 4, which are located on the front housing 21 and the rear housing 22, respectively. The central housing 2 is split into front and rear connected structures, so that the front drive group 3 and the rear drive group 4 in the crankshaft drive mechanism are correspondingly placed separately. This ensures the compact installation of the drive mechanism and avoids mutual interference between the front and rear drive components. The crankshaft drive mechanism directly links with the brown frame opening mechanism 5, resulting in a short transmission path and low power loss. This ensures the coordination between the opening action and the weaving action, laying the foundation for the subsequent weaving accuracy.

[0056] The front drive assembly 3 includes a first front crankshaft assembly 31 and a second front crankshaft assembly 32 installed at the front and rear ends of the front housing 21. The second front crankshaft assembly 32 includes drive wheels 321 and rear synchronous pulleys 322 located on both sides of the front housing 21. The drive wheels 321 and rear synchronous pulleys 322 are connected to the first front spindle 323. A drive motor 12 is installed in the lower base 1. The drive motor 12 is connected to a drive pulley 121 and is connected to the drive pulley 321 via a synchronous belt. The drive motor 12 adopts a servo drive motor 12 in the prior art. The synchronous belt drive has the advantages of precise transmission ratio and no slippage, and can transmit the motor power without deviation. The dual front-end spindles result in lower power loss than traditional gear transmissions, making them suitable for the high-speed operation requirements of ribbon weaving machines. The front-end first crankshaft assembly 31 includes a front-end second spindle 311, which is mounted on the front-end housing 21. One end of the front-end second spindle 311 extends to the outside of the front-end housing 21 and is fitted with a front synchronous pulley 312. The front synchronous pulley 312 is connected to the rear synchronous pulley 322 via a synchronous belt. Through the layout of the front-end first crankshaft assembly 31 and the front-end second crankshaft assembly 32, dual-path power output from the front end is achieved, distributing the drive load, improving the stability of the front-end drive, and avoiding wear and deformation caused by long-term high-load operation of a single crankshaft.

[0057] Several first eccentric wheels 324 and second eccentric wheels 313 are respectively installed on the first main shaft 323 and the second main shaft 311 at intervals. The first eccentric wheels 324 and second eccentric wheels 313 are distributed on both sides inside the front housing 21 and connected to the push-pull gate component 51. The eccentric wheel interval distribution design can accurately match the multiple execution units of the push-pull gate component 51 to realize multi-position synchronous push-pull drive, ensure the consistency of action in each area of ​​the push-pull gate component 51, avoid uneven opening of the brown frame caused by local lag or advance of action, and the two types of eccentric wheels are placed on both sides of the housing to make the front drive load evenly distributed, avoid the main shaft bending and housing deformation caused by the concentrated load on one side, and extend the service life of the main shaft and housing. At the same time, the eccentric wheel transmission can accurately convert the rotational motion of the main shaft into the linear reciprocating motion of the push-pull gate component 51, with high transmission efficiency and fast action response, which is suitable for the high-speed weaving needs of the ribbon loom and improves weaving efficiency.

[0058] The rear drive group 4 includes a rear first main shaft 41 and a rear second main shaft 42 spaced apart. The rear first main shaft 41 is mounted on the rear housing 22. The two ends of the rear first main shaft 41 are equipped with a first synchronous pulley 411 and a second synchronous pulley 412, which are located on both sides of the rear housing 22. The front second main shaft 311 is also equipped with a driven pulley 3111 and is connected to the first synchronous pulley 411 through a synchronous belt. The rear second main shaft 42 is equipped with a third synchronous pulley 421. The second synchronous pulley 412 is connected to the third synchronous pulley 421 through a double-sided toothed belt. The power source of the rear drive group 4 is the front second main shaft 311, realizing unified input and zoned output of the whole machine's power, ensuring the speed synchronization of the front drive group 3 and the rear drive group 4, and avoiding weaving misalignment caused by the disconnection of the front and rear actions.

[0059] Several third eccentric wheels 43 are staggered on the first rear spindle 41 and the second rear spindle 42. The third eccentric wheels 43 are connected to the connecting rod gate component 52, which is located between two sets of push-pull gate components 51. Both the connecting rod gate component 52 and the push-pull gate component 51 are connected to the frame component 53. The staggered installation of the third eccentric wheels 43 on the first rear spindle 41 and the second rear spindle 42 can adapt to the movement trajectory of the connecting rod gate component 52, converting the rotational motion of the spindle into the precise swing of the connecting rod. This drives the palm frame component 53 to move, with controllable stroke, improving the opening accuracy. The connecting rod closing component 52 is located between the two sets of push-pull closing components 51, forming a palm frame drive layout with push-pull on both sides and connecting rod in the middle. This achieves double horizontal opposition and completes the composite drive for palm frame opening. It can meet the opening requirements of conventional webbing and also adapt to the multi-dimensional opening action of complex webbing, improving the weaving adaptability of the equipment, improving the response speed of the opening action, matching the high-speed weaving rhythm, and improving the webbing production efficiency.

[0060] Based on the above structure, the drive motor 12 inside the lower base 1 is started. The motor drives the drive wheel 321 of the front second crankshaft assembly 32 to rotate via the drive pulley 121 and the synchronous belt, thereby driving the front first main shaft 323 to rotate. The rear synchronous pulley 322 on the front first main shaft 323 is linked to the front synchronous pulley 312 of the front first crankshaft assembly 31 via the synchronous belt, driving the front second main shaft 311 to rotate synchronously, completing the synchronous power transmission of the front double crankshaft assembly. At this time, the first and second eccentric pulleys 313 on the front double main shafts rotate with the main shaft, converting the rotational motion into linear reciprocating motion, driving the push-pull switch components 51 on both sides to move. At the same time, the driven pulley on the front second main shaft 311 transmits power to the first synchronous pulley 411 of the rear first main shaft 41 via the synchronous belt, driving the rear first main shaft 41 to rotate. The second synchronous pulleys 412 at both ends of the rear first main shaft 41 are connected to the drive pulley 321 of the drive second main shaft 311 to rotate via the synchronous belt. The third synchronous pulley 421 of the second main shaft 42 at the rear end, which is linked by the double-sided toothed belt, achieves precise synchronous rotation of the two main shafts at the rear end. The third eccentric pulley 43, which is installed alternately on the two main shafts at the rear end, rotates with the main shaft, converting the rotational motion into the swing of the connecting rod, which drives the connecting rod closing knife component 52 located between the two sets of push-pull closing knife components 51 to move, forming an intermediate driving force. The double horizontal opposing coordinated action formed by the push-pull closing knife component 51 and the connecting rod closing knife component 52 controls the lifting and opening and closing of the frame according to the requirements of the webbing pattern, so that the warp yarn forms a stable weaving opening. The weaving mechanism 6 is located between the shedding mechanism and the take-up mechanism. After the frame forms the weaving opening, it completes the introduction and interlacing process of the weft yarn to form the required webbing, and finally it is synchronously taken up by the tape take-up mechanism 7. The partitioned drive and synchronous transmission structure of the double horizontal opposing crankshaft ensures the consistency of the shedding accuracy and weaving rhythm, and improves the efficiency of the webbing and the regularity of the product.

[0061] In one embodiment, reference is made to Figure 1 , Figure 4 , Figure 6 and Figure 7The connecting rod-type knife-operated component 52 includes a push-pull connecting rod 521, which is mounted on the third eccentric wheel 43. The other end of the push-pull connecting rod 521 is connected to a lower connecting rod 522, which is connected to an upper connecting rod 523. The upper connecting rod 523 is connected to a knife-operated component 524. The connecting rod assembly has a multi-stage hinged structure. The knife-operated component 524 is the actuating end. When the first rear spindle 41 and the second rear spindle 42 rotate, the knife-operated components 524 intersect and form a height difference, utilizing the crank-connecting rod mechanism... The principle of dynamic conversion is that when the first main shaft 41 and the second main shaft 42 at the rear end rotate, they drive the third eccentric wheel 43 to make a circular motion. The eccentric wheel drives the push-pull connecting rod 521 to make a reciprocating swing. Through the force transmission and motion direction adjustment of the lower connecting rod 522 and the upper connecting rod 523, the swing of the push-pull connecting rod 521 is converted into the precise swing motion of the shut-off piece 524 around the axis. The opposing rotation of the two main shafts at the rear end causes multiple shut-off pieces 524 to swing in an alternating manner and form a height difference, which in turn drives the connected brown frame to achieve the staggered warp opening.

[0062] In one embodiment, reference is made to Figure 1 , Figure 3 , Figure 4 and Figure 5 The push-pull gate knife component 51 includes a long-handled gate knife 511 and a short-handled gate knife 512. A long push-pull connecting rod 3241 is installed on the first eccentric wheel 324, and a short push-pull connecting rod 3131 is installed on the second eccentric wheel 313. The first eccentric wheel 324 is connected to the long-handled gate knife 511 through the long push-pull connecting rod 3241, and the second eccentric wheel 313 is connected to the short-handled gate knife 512 through the short push-pull connecting rod 3131. The eccentric wheels of the front first crankshaft assembly 31 and the front second crankshaft assembly 32 rotate synchronously. By utilizing the difference in connecting rod length, the circular motion of the eccentric wheels is converted into reciprocating push-pull motions of different strokes for the long-handled gate knife 511 and the short-handled gate knife 512. The long push-pull connecting rod 3241 drives the long-handled gate knife 511 to achieve a large stroke swing, and the short push-pull connecting rod 3131 drives the short-handled gate knife 512 to achieve a small stroke swing. The two stroke gate knife movements are adapted to the different opening width requirements of the brown frame.

[0063] In one embodiment, reference is made to Figure 1 , Figure 3 , Figure 4 and Figure 6 The push-pull gate knife component 51 also includes a first gate knife shaft component 513, which passes through the front end housing 21 and is fixed thereto. Both the short-handled gate knife 512 and the long-handled gate knife 511 have a first bearing hole. The short-handled gate knife 512 and the long-handled gate knife 511 are mounted side by side on the first gate knife shaft component 513 through the first bearing hole.

[0064] The connecting rod knife assembly 52 also includes a second knife shaft 525, which passes through the rear end housing 22 and is fixed thereon. The knife 524 has a second bearing hole. Several knife 524 are mounted side by side on the second knife shaft 525 through the second bearing hole. The push-pull knife assembly 51 and the connecting rod knife assembly 52 provide a stable rotation and swing fulcrum for the knife with the fixed shaft, limiting the movement trajectory of the knife and preventing lateral deviation and jamming during knife movement. At the same time, the side-by-side mounting method ensures that all the knives on the same shaft move synchronously, ensuring that the opening action of multiple frames is consistent, thereby improving processing efficiency.

[0065] In one embodiment, reference is made to Figure 1 , Figure 3 and Figure 4 The outer side of the rear housing 22 is connected to a pulley 221 via a shaft. Two sets of pulleys 221 are provided and distributed at intervals at the upper and lower ends of the third synchronous pulley 421. By utilizing the changing direction of the pulleys 221 and the double-sided meshing characteristics of the double-sided toothed belt, the direction of power transmission is reversed. When the first main shaft 41 at the rear drives the second synchronous pulley 412 to rotate forward, the double-sided toothed belt, guided by the upper and lower pulleys 221, drives the third synchronous pulley 421 to rotate in reverse synchronously.

[0066] The double-sided toothed belt meshes with the second synchronous pulley 412, the third synchronous pulley 421, and two sets of pulleys 221 respectively. Through the cooperation of the double-sided toothed belt and the pulleys 221, when the second synchronous pulley 412 rotates forward, the third synchronous pulley 421 rotates in reverse synchronously. When the first main shaft 41 at the rear rotates, it drives the second synchronous pulley 412 to rotate forward. The double-sided toothed belt moves under the drive of the second synchronous pulley 412. Guided by the upper and lower sets of pulleys 221, it changes the transmission direction and drives the third synchronous pulley 421 to rotate in reverse, so that the second synchronous pulley 412 and the third synchronous pulley 421 can rotate in the same direction. This makes the staggered action of the connecting rod knife precise and controllable, ensuring the staggered swing of the knife part 524 and the symmetrical opening of the frame.

[0067] In one embodiment, reference is made to Figure 1 , Figure 5 , Figure 6 , Figure 7 and Figure 11 The brown frame component 53 includes a brown frame body 531 and a fixed edge strip 532. The brown frame body 531 has a stand. Several brown frame bodies 531 are connected to the push-pull switch component 51 and the connecting rod switch component 52 respectively through the stand. The push-pull switch component 51 and the connecting rod switch component 52 drive the movement of the brown frame body 531.

[0068] The fixed edge strip 532 has an opening, and the brown frame body 531 is partially inserted into the opening to connect the brown frame body 531 and the fixed edge strip 532. The fixed edge strip 532 has threaded holes that communicate with the opening. The threaded holes are used to fasten the brown frame body 531 through the four corner nuts. The legs of the brown frame body 531 are inserted into the opening of the fixed edge strip 532. The dimensional tolerance control of the opening enables the rapid positioning of the brown frame body 531. The perpendicularity and parallelism of the brown frame body 531 can be guaranteed without additional calibration tools. When the four corner nuts are tightened through the threaded holes, they squeeze the legs of the brown frame body 531 from the side to form a ring-shaped fixation, so that there is no relative displacement between the brown frame body 531 and the fixed edge strip 532. Furthermore, a single group of brown frame bodies 531 can be disassembled by loosening the nuts without disassembling the whole body. This is suitable for warp yarn specification replacement or brown frame repair needs.

[0069] In one embodiment, reference is made to Figure 1 , Figure 2 , Figure 7 and Figure 11 The frame 11 has side plates 111 on both sides. The side plates 111 can be connected by welding steel plates. The slots 1111 are rectangular. The brown frame component 53 is located between the two sets of side plates 111. The side plates 111 have several slots 1111 distributed at intervals. By embedding the two sides of several fixed edge strips 532 into the slots 1111 respectively, the brown frame component 53 can move relative to each other along the length of the slots 1111. The linear slots 1111 provide precise motion guidance for the brown frame component 53, limiting the movement direction of the brown frame component 53 to a straight up-and-down reciprocating motion along the slots 1111. This prevents the brown frame component 53 from deviating, jamming, or deviating from its movement trajectory under the action of the closing knife component. At the same time, the interval distribution of the slots 1111 matches the number of brown frame components 53, so that each brown frame component 53 has an independent movement track, preventing the brown frame components 53 from colliding or tangling with each other, and ensuring the smoothness and accuracy of the opening operation of the brown frame component 53.

[0070] In one embodiment, reference is made to Figure 1 and Figure 2 The frame 11 is equipped with a warp yarn breakage protection device 13 and a weft yarn feeding device 8. The weft yarn feeding device 8 is located between the warp yarn breakage protection device 13 and the brown frame opening mechanism 5. The warp yarn breakage protection device 13 is an independent monitoring structure.

[0071] The weft feeding device 8 includes a yarn feeding wall plate 81, which is mounted on the frame 11. A yarn feeding shaft 82 is installed between the yarn feeding wall plates 81. One end of the yarn feeding shaft 82 extends to the outside of the machine base and is equipped with a driven wheel 821. A driving wheel 3231 is also installed on the front first main shaft 323. The driven wheel 821 and the driving wheel 3231 are located on the same horizontal plane and are connected by a synchronous belt. A yarn feeding wheel 822 is installed on the yarn feeding shaft 82, which is directly driven by the power of the front first main shaft 323. The weft yarn feeding device 8 mechanically synchronizes the weft yarn feeding speed with the warp yarn shedding frequency, avoiding defects such as uneven weft yarn density, weft yarn accumulation, or breakage caused by excessively fast or slow weft yarn feeding, and ensuring the coordination of weft insertion and beat-up processes. Meanwhile, the warp yarn breakage protection device 13 monitors the tension and integrity of the warp yarn in real time. When warp yarn breaks or loosens, the device immediately triggers a stop command to prevent the equipment from continuing to weave when there is no warp yarn or the warp yarn is abnormal, thus avoiding the generation of defective products from the source and reducing raw material loss.

[0072] In one embodiment, reference is made to Figure 1 , Figure 7 and Figure 10 The switch blade component 524 includes a switch blade arm 5241 and a switch blade 5242. The switch blade arm 5241 has a recess 52411. When the switch blade 5242 is inserted into the recess 52411, a portion of the switch blade 5242 is located on the outer periphery of the switch blade arm 5241. The inner wall of the recess 52411 matches the outer periphery of the switch blade 5242. The recess 52411 provides precise installation positioning for the switch blade 5242.

[0073] Bolt holes are evenly distributed on the recessed part 52411. The bolt holes in the recessed part 52411 are countersunk holes, and the bolt heads are not exposed to avoid collision with the brown frame component 53. The switch blade 5242 is provided with mounting holes at the positions corresponding to the bolt holes. When the bolt holes and mounting holes are aligned and connected with bolts, the switch blade 5242 is fixedly installed on the switch arm 5241. The switch blade 5242 is a vulnerable part that is in direct contact with the brown frame. It is prone to wear due to long-term swinging friction. The split structure allows for individual disassembly and replacement without replacing the entire switch component 524. Furthermore, the positioning pin formed by the bolts can ensure the positional accuracy of the switch blade 5242 after installation and the fitting gap with the switch arm 5241.

[0074] In one embodiment, reference is made to Figure 1 , Figure 2 , Figure 8 and Figure 9The weaving mechanism 6 includes a weaving box 61, on which a needle holder 62 is mounted. The needle holder 62 is equipped with several weaving heads 621 spaced apart. The spaced distribution of the weaving heads 621 ensures uniform weaving density across the entire width of the webbing. The tips of the knitting needles 6311 are polished to reduce friction with the warp yarns and prevent the warp yarns from being scratched or broken. A knitting needle shaft 63 rotates inside the weaving box 61. Several knitting needle arms 631 spaced apart are mounted on the knitting needle shaft 63. Each knitting needle arm 631 has a knitting needle 6311. The knitting needle arms 631 drive the knitting needles 6311 to perform reciprocating piercing and hooking motions, thereby interlacing the weft yarns and warp yarns to form a fabric tape.

[0075] The tape winding mechanism 7 includes a winding wall plate 71, which is mounted on the frame 11. Two sets of belt guide shafts 72 are rotatably arranged between the winding wall plates 71, forming a gap between the two sets of belt guide shafts 72 through which the tape passes. A fixed shaft 73 is also provided on the winding wall plate 71, and a belt pressing handle 731 is installed on the fixed shaft 73. Several belt pressing handles 731 are provided and are spaced apart along the length of the fixed shaft 73. The belt guide shafts 72 can be made of rubber with anti-slip texture to prevent the tape from slipping during winding. The woven tape passes through the gap of the belt guide shafts 72, and the anti-slip texture prevents the tape from shifting. The belt pressing handles 731 control the tape winding tension by adjusting the pressing force.

[0076] In one embodiment, reference is made to Figure 1 and Figure 12 The front box 21 has a support platform 211 on which the tape winding mechanism 7 is placed. The weaving box 61 is located in the middle of the front box 21. The bottom of the front box 21 has machine feet 212 around its perimeter and is fixed to the lower machine base 1. Bearing seats 213 are provided on both sides of the front box 21 for placing the first front main shaft 323 and the second front main shaft 311. Traditional ribbon weaving machines use two wall panels spliced ​​together, with bearings installed on the left and right wall panels respectively. The weaving mechanism 6, main shaft and steel buckle shaft are placed between the two wall panels. The installation accuracy is not high and the stability is relatively low. After long-term operation of the machine, the left and right wall panels are prone to misalignment and deformation. By using an integrated box 2 in the middle, the traditional splicing of two left and right wall panels is abandoned, thereby improving the processing accuracy of the box, avoiding the accuracy error caused by the splicing installation of the traditional structure, improving the overall strength and accuracy of the weaving mechanism, and reducing the vibration and noise of the ribbon weaving machine.
