Description

Technical Field

[0001] This application relates to the field of weaving machinery accessories, and in particular to a device for reed turning and pushing. Background Technology

[0002] The reed is a key component in weaving machinery and is widely used in the production of filter products such as polyester mesh and metal mesh. It is mainly used to determine the warp yarn arrangement density and fabric width, and has an important impact on the stability of the weaving process and product quality.

[0003] In the production of reeds, it is often necessary to flip and push the reeds, especially to flip them 180°, to meet the requirements of subsequent processes such as glue injection, reed placement, or handling. However, reeds are often quite long, heavy, and structurally prone to deformation under stress. Therefore, the flipping and pushing process requires a high degree of operational stability, synchronization, and positioning accuracy.

[0004] Currently, reed production mostly employs manual flipping and pushing methods, requiring multiple people to work together. This method is labor-intensive, inefficient, and struggles to precisely control the flipping angle and the uniformity of force application. Furthermore, uneven force distribution, angle deviations, and inaccurate positioning are prone to occur during the flipping process, leading to damage such as reed tooth breakage and reed distortion. This not only affects the quality of the finished reed but also negatively impacts the precision and stability of subsequent woven products. Therefore, the existing manual flipping and pushing methods cannot meet the demands for efficient, stable, and low-damage flipping operations in reed production. Summary of the Invention

[0019] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

Those skilled in the art can understand the specific meaning of the above terms in the embodiments of the present invention according to the specific circumstances.

[0021] Please refer to Figures 1-6 As shown, this embodiment of the invention provides a device for flipping and pushing a reed, including a frame 1, a first mounting plate 2, a pushing mechanism 3, a transmission mechanism 4, a flipping mechanism 5, a second mounting plate 6, a first fixing rod group 7, and a second fixing rod group 8.

[0022] The frame 1 is a vertical frame structure, including a top plate 10, support legs 11, connecting plates 12, and a support plate 13. There are four support legs 11, evenly distributed at the four corners of the bottom surface of the top plate 10. The four support legs 11 are divided into two groups, with a connecting plate 12 positioned between the bottom of the two support legs 11 in each group. A support plate 13 is positioned between the two support legs 11 in each group. The two ends of the support plate 13 are connected to the top plate 10 and the connecting plate 12, respectively. The connecting plate 12 provides a fixed position for the bottom of the support plate 13 and can connect two support legs 11, making the frame 1 more stable. The bottom of the support legs 11 is equipped with mounting feet for easy leveling and fixing of the equipment.

[0023] The top plate 10 of the frame 1 includes two sets of slots, which are respectively disposed on both sides of the top plate 10. Each set of slots includes two tilting and swinging slots 101 and one pushing slot 102. The tilting and swinging slots 101 and the pushing slots 102 are parallel. The pushing slots 102 of the two sets of slots are adjacent to each other. The pushing slot 102 is a through slot extending inward from the side of the top plate 10.

[0024] Both the first mounting plate 2 and the second mounting plate 6 are disposed within the inner cavity of the frame 1, with the first mounting plate 2 located at the top. Specifically, the four corners of the first mounting plate 2 are fixed to the upper parts of the four support legs 11. The four corners of the second mounting plate 6 are fixed to the middle parts of the two support legs 11 and the two support plates 13. Further, the four corners of the first mounting plate 2 are fixed to the upper parts of the four support legs 11 by fixing brackets 21 and bolts. The four corners of the second mounting plate 6 are fixed to the middle parts of the two support legs 11 and the two support plates 13 by fixing brackets 21 and bolts. The first mounting plate 2 is an integral plate structure.

[0025] The pushing mechanism 3 includes two sets, both of which are mounted on the first mounting plate 2 and located at the pushing slot 102 of the corresponding slot group, and are configured to push the reed to the designated position.

[0026] The transmission mechanism 4 is mounted on the second mounting plate 6 and is fixed to the frame 1 by the first fixing rod group 7.

[0027] The flipping mechanism 5 includes two sets. One end of each flipping mechanism 5 is connected to the transmission mechanism 4, and the other end is located at the two flipping swing slots 101 of the corresponding slot group, and is fixed to the frame 1 by the second fixed rod group 8. It is used to perform a flipping action under the drive of the transmission mechanism 4 when the pushing mechanism 3 pushes the reed to the designated position so that the reed flips.

[0028] The device for flipping and pushing a reed provided in this application embodiment initially places the reed in the pushing groove 102 of the top plate 10 of the frame 1. The pushing mechanism 3 is activated, pushing the reed along the pushing groove 102 to the designated position. This action is achieved smoothly by the pushing mechanism 3 being mounted on the first mounting plate 2. Once the reed reaches the designated position, the transmission mechanism 4 starts working, driving the flipping mechanism 5 through its structure fixed to the second mounting plate 6 and the first fixed rod group 7. One end of the flipping mechanism 5 is connected to the transmission mechanism 4, and the other end is located at the flipping swing groove 101 and fixed to the frame 1 by the second fixed rod group 8, ensuring stable support. Driven by the transmission mechanism 4, the flipping mechanism 5 performs a flipping action, causing the reed to complete a 180-degree flip to adapt to subsequent processes. The device for flipping and pushing a reed provided in this application embodiment, through the coordinated automated operation of the pushing mechanism 3 and the flipping mechanism 5, solves the problem of low work efficiency caused by manual flipping, significantly reducing labor costs and time consumption. The entire automated process requires no manual intervention. The sequential push and flip actions ensure operational continuity and reliability. Simultaneously, the synchronous control of the two flipping mechanisms 5 avoids uneven force application and flipping angle deviations during multi-operation, eliminating mechanical damage such as reed tooth breakage or reed twisting, thereby improving production quality and finished product qualification rate. Through the integrated design of the frame 1, slot groups, first mounting plate 2, and second mounting plate 6, combined with the collaborative work of the push mechanism 3 and flipping mechanism 5, the device achieves automatic pushing and flipping of the reed, significantly improving operational efficiency. The frame design of the slot groups on both sides of the top plate 10 of the frame 1 and the double mounting plates, as well as the arrangement of the first fixed rod group 7, second fixed rod group 8, and slot groups, provides versatility and adaptability, enabling the device to adapt to the pushing and flipping needs of reeds of different specifications, enhancing the flexibility and scalability of the production line, and achieving an overall efficient, reliable, and highly adaptable working effect. It meets the requirements for efficient, stable, and low-damage flipping operations during reed production.

[0029] The present invention overcomes the shortcomings of existing steel reed turning and pushing processes, which rely on manual operation, have low turning efficiency, poor operational stability, insufficient positioning accuracy, and are prone to damage to the steel reed. It provides a steel reed turning device and turning method to achieve efficient, stable and precise turning of the steel reed, thereby improving the automation level of the steel reed production process and the stability of product quality.

[0030] The pushing mechanism 3, transmission mechanism 4, and flipping mechanism 5 work together to enable the device to perform sequential actions of conveying and flipping the reed. After the reed is transported to the designated position, the flipping mechanism 5 begins to flip it. This device has a simple structure, high reliability, and can effectively flip long workpieces such as reeds. It can achieve automatic flipping of the reed, and the operator can directly operate the reed on the workbench. It can solve the problem of the difficulty in flipping existing reeds. The flipping mechanism 5 works in conjunction with the pushing mechanism 3, has a simple structure, and is easy to debug and replace.

[0031] like Figure 3 and Figure 5 As shown, the pushing mechanism 3 includes a guide rail 30, a slider 31, a sliding plate 32, a first driving component 33, a second driving component 35, a U-shaped stop 36, a connecting seat 37, and an L-shaped stop 38. The first driving component 33 can be a servo motor. The guide rail 30 includes at least one rail, which is arranged parallel to the first mounting plate 2. If there are two or more guide rails 30, they are arranged parallel to each other. Preferably, as shown... Figure 3 and Figure 5 As shown, the guide rail 30 includes two rails, which is both cost-effective and ensures the stability of the sliding plate 32 during sliding. The guide rail 30 can be a linear guide rail.

[0032] The slider 31 includes at least one slider 31, which is slidably mounted on each guide rail 30. A sliding plate 32 is mounted on the slider 31. The sliding plate 32 is a machined integral plate. The output end of the first drive unit 33 is connected to the sliding plate 32. The first drive unit 33 is fixed to the end of the first mounting plate 2 via a triangular mounting base 34, and its output shaft is connected to the sliding plate 32 via a threaded hole. The two first drive units 33 are driven by a synchronous control signal to ensure that the movement speed, stroke, and phase of the two sets of pushing mechanisms 3 are completely consistent. An adjustment hole is provided on the sliding platform for fine-tuning the drive connection position.

[0033] The top of the U-shaped stop 36 is fixed to the output shaft of the second drive member 35. The top of the U-shaped stop 36 and the output shaft of the second drive member 35 are connected through a threaded hole. The connecting seat 37 is engaged inside the U-shaped stop 36, and the first bolt 39 passes between the two side walls of the U-shaped stop 36 and the two side walls of the connecting seat 37. The U-shaped stop 36 and the first bolt 39 are slidably connected to the side of the connecting seat 37 through a sliding groove. One end of the L-shaped stop 38 is located in the inner cavity of the connecting seat 37 and is hinged by the first bolt 39 and the second bolt 3A. The other end is located at the push groove 102. The sliding groove of the connecting seat 37 allows the U-shaped stop 36 to slide and control the angle of the L-shaped stop 38. The position can be adjusted perpendicular to the pushing direction to adapt to different material specifications.

[0034] The pushing mechanism 3 provided in this embodiment firstly involves a first driving component 33 (such as a servo motor) connected to a sliding plate 32 via an output shaft, driving the sliding plate 32 to move on a guide rail 30. The guide rail 30 is parallel to the first mounting plate 2, and the slider 31 slides on the guide rail 30, supporting the movement of the sliding plate 32. When the first driving component 33 is activated, the output shaft drives the sliding plate 32 to move linearly along the guide rail 30, providing the basic power for the pushing action. Simultaneously, the output shaft of the second driving component 35 is fixed to a U-shaped stop 36 via a threaded hole. A connecting seat 37 is fitted inside the U-shaped stop 36, and a first bolt 39 passes between the U-shaped stop 36 and the connecting seat 37, allowing the U-shaped stop 36 to slide along the groove of the connecting seat 37. One end of an L-shaped stop 38 is hinged to the inner cavity of the connecting seat 37 and fixed by a first bolt 39 and a second bolt 3A, while the other end is located at the pushing groove 102. During the pushing process, the second drive component 35 adjusts the stroke of the U-shaped stop 36 in the slide groove, thereby adjusting the angle of the L-shaped stop 38. This, in turn, drives the L-shaped stop 38 via the connecting seat 37, precisely pushing the reed to the designated position in the pushing groove 102. For example, when the reed is placed in the pushing groove 102, the first drive component 33 pushes the sliding plate 32 forward, causing the L-shaped stop 38 to contact the reed and apply a pushing force. The sliding design of the U-shaped stop 36 and the connecting seat 37 allows for fine-tuning of the position and angle of the L-shaped stop 38 to accommodate reeds of different specifications. The entire working process is controlled in a coordinated manner. The guide rail 30 and the slider 31 ensure smooth guidance, the first drive component 33 provides the main pushing force, the second drive component 35 adjusts the angle, the U-shaped stop 36 and the connecting seat 37 achieve a flexible connection, and the L-shaped stop 38 directly performs the pushing action. This pushing mechanism 3 uses the first drive component 33 to drive the sliding plate 32 to move linearly on the guide rail 30. Two sets of pushing mechanisms 3 are synchronously controlled, and with the high-precision guidance of the linear guide rail 30, the reed is automatically pushed and flipped. After the operation is completed, the first driving component 33 rotates, driving the sliding plate 32 to reset, waiting for the next cycle.

[0035] The push mechanism 3 reduces manual intervention and improves efficiency through automated pushing. The linear design of the guide rail 30 and slider 31 ensures the accuracy of the pushing path, preventing the reed from shifting or being damaged during movement. The sliding mechanism of the U-shaped stop 36 and connecting seat 37 allows for quick adjustment, enabling the device to adapt to reeds of different sizes and enhancing versatility. The hinged design of the L-shaped stop 38 provides angular flexibility, ensuring uniform force on the reed during pushing and reducing the risk of reed tooth breakage. Overall, the device of this embodiment reduces labor costs and time consumption while improving production quality and finished product qualification rate.

[0036] The device for flipping and pushing the reed also includes a limit switch A. A limit switch A is installed at the end position of at least one sliding plate 32 of the pushing mechanism 3 on the second mounting plate 6. Limit switch A is electrically connected to the first drive member 33. When the sliding plate 32 of the pushing mechanism 3 moves to the designated position, it touches the limit switch A, and the signal causes the first drive member 33 to stop working. During operation, this ensures that the reed is accurately pushed to the flipping position, avoiding overtravel. Automatic stopping improves pushing accuracy and reduces errors; the electrical connection enables instant response, optimizes the work cycle, thereby improving overall efficiency and reducing the need for manual intervention. If the first drive member 33 is high-power, the device also includes a relay, with limit switch A electrically connected to the relay, and the relay electrically connected to the first drive member 33, thereby ensuring the contact life of limit switch A.

[0037] like Figure 3 and Figure 5 A schematic diagram of a single limit switch A is shown. Since the pushing mechanism 3 moves synchronously, setting one limit switch A can save costs while achieving the required functions of the device. Optionally, there can be two limit switches A, with one limit switch A installed at the end position of the sliding plate 32 of each pushing mechanism 3, thus enabling one switch to be used as a backup.

[0038] like Figure 2 As shown, the transmission mechanism 4 includes a third drive component 40, a drive gear 41, a first bearing assembly 42, a transmission gear 43, a first main shaft 44, a second bearing assembly 45, and a driven gear 46. The third drive component 40 can be a servo motor.

[0039] The third drive component 40 is mounted on the second mounting plate 6, and a drive gear 41 is sleeved on the output shaft. This third drive component 40 can be a servo motor. The servo motor is fixed to the second mounting plate 6 by bolts, and the output shaft is connected to the drive gear 41 by a key.

[0040] A first bearing assembly 42 is provided on each side of the transmission gear 43. The transmission gear 43 and the two first bearing assemblies 42 are all sleeved on the first main shaft 44. The two first bearing assemblies 42 are fixed to the first fixed rod group 7 so that the transmission gear 43 is fixed to the frame 1 through the first fixed rod group 7. The drive gear 41 meshes with the transmission gear 43.

[0041] A driven gear 46 and two second bearing assemblies 45 are respectively fitted at both ends of the first main shaft 44. The two second bearing assemblies 45 are respectively positioned on both sides of the driven gear 46 at corresponding locations. The two second bearing assemblies 45 are fixed to the first fixed rod assembly 7, so that the driven gear 46 is fixed to the frame 1 via the first fixed rod assembly 7. The transmission gear 43 located in the middle of the first main shaft 44 smoothly transmits force to both sides. Both driven gears 46 are fixed to the frame 1 via the first fixed rod assembly 7. Figure 2 As shown, the first fixed rod group 7 includes six fixed rods, and the driven gear 46 and the transmission gear 43 are fixed by two fixed rods respectively.

[0042] The transmission mechanism 4 in this embodiment of the application transmits power based on a gear system. A third driving component 40 (such as a servo motor) is fixed to the second mounting plate 6, and its output shaft is fitted with a driving gear 41. The driving gear 41 meshes with a transmission gear 43, and first bearing assemblies 42 are provided on both sides of the transmission gear 43 to support rotation. A first main shaft 44 passes through the transmission gear 43 and two second bearing assemblies 45, which are fixed to the first fixed rod group 7 to ensure structural stability. When the driving gear 41 rotates, it drives the transmission gear 43 to rotate, and the transmission gear 43 then drives the first main shaft 44 to move. A driven gear 46 is fitted at each end of the first main shaft 44, and second bearing assemblies 45 are also provided on both sides of each driven gear 46, similarly fixed to the first fixed rod group 7. For example, when the third driving component 40 is activated, the driving gear 41 drives the transmission gear 43, and the transmission gear 43 transmits power to the driven gears 46 on both sides through the first main shaft 44; the first bearing assemblies 42 and the second bearing assemblies 45 respectively bear radial and axial loads to prevent gear misalignment. During operation, the precise coordination of each component ensures uniform power distribution: the driving gear 41 serves as the input source, the transmission gear 43 serves as the intermediary, the driven gear 46 outputs power to the flipping mechanism 5, and the first fixed rod group 7 provides rigid support.

[0043] The transmission mechanism 4 in this embodiment achieves power synchronization through multi-stage gear meshing, ensuring coordinated operation of the flipping mechanism 5. The use of the first bearing assembly 42 and the second bearing assembly 45 reduces friction and vibration, extending equipment life. The fixing design of the first fixed rod group 7 enhances overall rigidity, preventing loosening or deformation during transmission. It solves the synchronization problem in manual operation, improves the reliability and accuracy of reed flipping, and thus improves production efficiency and finished product quality.

[0044] like Figure 2 and Figure 3As shown, the transmission mechanism 4 also includes a coupling 47. A coupling 47 is fitted onto the first main shaft 44 between the transmission gear 43 and each driven gear 46. This facilitates the disassembly and installation of the first main shaft 44. Adding the coupling 47 to the transmission mechanism 4 simplifies assembly and maintenance. For example, when the first main shaft 44 needs to be disassembled or installed, the coupling 47 allows the first main shaft 44 to be connected in sections, absorbing minor deviations through its flexible structure to ensure smooth gear meshing. During operation, power is transmitted from the transmission gear 43 to the driven gear 46 via the coupling 47, which acts as a buffer to prevent transmission failure due to installation errors. This makes the assembly of the first main shaft 44 easier, eliminating the need for precise alignment, improving maintainability and reliability, reducing assembly time, and lowering maintenance costs; the buffering function of the coupling 47 protects the gears from impact damage, extending the life of the transmission system. Overall, this enhances the adaptability and durability of the device.

[0045] like Figure 6 As shown, the flipping mechanism 5 includes a drive gear 50, a third bearing assembly 51, a second main shaft 52, a flipping component 53, and a connecting rod 54. The drive gear 50 meshes with the transmission mechanism 4 and is fixed to the second main shaft 52, with a third bearing assembly 51 on each side. Specifically, the drive gear 50 meshes with the driven gear 46 of the transmission mechanism 4. The drive gear 50 is fixed to the second main shaft 52 via a key fit. Two third bearing assemblies 51 are fitted onto the second main shaft 52. A set of flipping components 53 is fixed to each end of the second main shaft 52.

[0046] Each set of tilting components 53 includes a crank 531, a first rod end spherical bearing 532, a connecting rod 533, a second rod end spherical bearing 534, a first tilting rod 535, and a second tilting rod 536. The first ends of the crank 531 of each set of tilting components 53 are respectively fitted onto both ends of the second main shaft 52. When stationary, the two crank 531s are at a 180° angle. This ensures that the first tilting rod 535 and the second tilting rod 536 at the ends of the two sets of tilting components 53 are symmetrically arranged, guaranteeing that the phase and stroke of the dual-station movement are consistent.

[0047] Specifically, the first end of the crankshaft 531 is fixed to the second spindle 52 by a double-ended bolt. The second spindle 52 drives the crankshaft 531 to rotate. For example, the crankshaft 531 is 70 mm long.

[0048] The second end of the crankshaft 531 is connected to the first end of the first rod end spherical bearing 532. The crankshaft 531 is connected to the second main shaft 52 as the driving element. The first rod end spherical bearing 532 has a size of φ10.

[0049] The second end of the first rod end spherical bearing 532 is connected to the first end of the connecting rod 533. The second end of the connecting rod 533 is connected to the first end of the second rod end spherical bearing 534. The second end of the second rod end spherical bearing 534 is connected to the first end of the first tilting rod 535. The second rod end spherical bearing 534 has a size of φ10. The total length of the connecting rod 533, the first rod end spherical bearing 532, and the second rod end spherical bearing 534 is 280mm.

[0050] The second end of the first flipping rod 535 is connected to the first end of the second flipping rod 536, and the first flipping rod 535 and the second flipping rod 536 are at a preset angle. The second ends of the first flipping rods 535 of the two sets of flipping assemblies 53 are connected by a connecting rod 54. Figure 4 As shown, the connecting rod 54 passes through the two tilting swing slots 101 on the top plate 10 of the frame 1, and the second tilting rods 536 are respectively located at the corresponding tilting swing slots 101, so that the two second tilting rods 536 swing in the same phase. The end first tilting rod 535 and the second tilting rod 536 swing through the connecting rod 533, and the first tilting rod 535 and the second tilting rod 536 of the two sets of tilting components 53 achieve a swing amplitude of 180° through the connecting rod 54.

[0051] The flipping mechanism 5 adopts a crank-rocker structure, powered by a third drive member 40 and driven by gears. The crank 531 is the driving member and rotates at a constant speed around its axis. The crank 531 drives the connecting rod 533, causing it to reciprocate. The connecting rod 533 acts as a swing arm and is the main component of the flipping mechanism 5 for flipping the reed. The first flipping rod 535 and the second flipping rod 536 swing through the connecting rod 533. The drive gear 41, driven gear 46, and transmission gear 43 of the transmission mechanism 4, along with the drive gear 50 of the flipping mechanism 5, achieve multi-stage gear transmission, connected in series via the first main shaft 44. By adjusting the gear ratio between the drive gear 41 and driven gear 46, and between the transmission gear 43 and drive gear 50, the motion frequency and stroke can be changed. This ensures that when the crank 531 rotates, it can drive the first flipping rod 535 and the second flipping rod 536 to reciprocate.

[0052] The flipping mechanism 5 uses multi-stage gear series transmission to ensure that the movement phase of the two sets of connecting rods 533 and the flipping rod is consistent. The gears and connecting rods 533 are rigidly transmitted without elastic deformation, and can withstand large axial and radial loads. By adjusting the gear ratio, the length of the connecting rod 533, and the motor speed, it can flexibly adapt to the operating requirements of different strokes, frequencies and loads.

[0053] The operation of the flipping mechanism 5 in this embodiment involves a complex linkage system. A drive gear 50 meshes with the driven gear 46 of the transmission mechanism 4 and is fixed to the second main shaft 52. Third bearing assemblies 51 are provided on both sides of the second main shaft 52 to support rotation. A set of flipping assemblies 53 is fixed to each end of the second main shaft 52. Each set includes a crank 531, a first rod end spherical bearing 532, a connecting rod 533, a second rod end spherical bearing 534, a first flipping rod 535, and a second flipping rod 536. The first end of the crank 531 is fixed to the second main shaft 52, and the second end is connected to the first rod end spherical bearing 532. The other end of the first rod end spherical bearing 532 is connected to the connecting rod 533, which in turn is connected to the first flipping rod 535 via the second rod end spherical bearing 534. The first flipping rod 535 and the second flipping rod 536 are at a preset angle (e.g., 130°), and the two sets of flipping assemblies 53 are synchronized via a connecting rod 54. For example, when the drive gear 50 rotates, the second main shaft 52 drives the crank 531 to rotate. The crank 531 pulls the connecting rod 533 through the first rod end spherical bearing 532. The connecting rod 533 then drives the first tilting rod 535 and the second tilting rod 536 to swing at the tilting swing groove 101 through the second rod end spherical bearing 534. The connecting rod 54 connects the two sets of first tilting rods 535 to ensure consistent action. During operation, the linkage of each component realizes the 180-degree rotation of the reed: the crank 531 acts as the driving component, the spherical bearing provides a flexible connection, the connecting rod 533 transmits power, and the tilting rod performs the swinging motion.

[0054] The flipping mechanism 5 of this embodiment achieves smooth flipping and efficient synchronization. The crank-rocker structure optimizes the motion trajectory, reducing mechanical impact; the spherical bearing allows for minor adjustments, preventing rigid damage; and the connecting rod 54 ensures synchronization between two workstations, improving flipping accuracy. This solves the asynchrony problem in manual flipping, reduces equipment wear, and improves production quality.

[0055] Optionally, the preset angle is 130°. The 130° preset angle directly affects the flipping trajectory and ensures that the second flipping rod 536 is below the top plate 10 of the frame 1 during a certain flipping process. The first flipping rod 535 and the second flipping rod 536 are fixed at a 130° angle, which optimizes the swing path through design. For example, when the flipping mechanism 5 operates, the crank 531 drives the connecting rod 533, and the 130° angle maximizes the swing range of the first flipping rod 535 and the second flipping rod 536, ensuring that the reed completes a 180-degree flip at the flipping swing groove 101. During operation, this angle calculation is based on mechanical analysis, reducing ineffective strokes and improving efficiency. Optimized angles reduce energy loss, making the flipping action more efficient; precise trajectory control reduces the risk of reed twisting and improves the finished product yield. Overall, this enhances the reliability and production efficiency of the device.

[0056] The connecting rod 533 has a forward and reverse thread adjustment section in the middle, making it a length-adjustable connecting rod 533, thus allowing for fine-tuning of its length and reciprocating stroke. For example, when assembling or adapting to different sizes of reeds, the operator rotates the adjustment section of the connecting rod 533 to change its length; this affects the lever arm distance from the crank rod 531 to the tilting rod, thereby adjusting the tilting amplitude. During operation, the adjustment section remains stable during the movement of the tilting mechanism 5, ensuring continuous power transmission. The fine-tuning function allows the device to handle reeds of different sizes, reducing the need for parts replacement; precise control of the tilting stroke avoids over- or under-rotation. This reduces production costs and enhances the versatility of the production line.

[0057] The device for reed flipping and pushing also includes a limit switch 9. A limit switch 9 is installed on the bottom surface of the top plate 10 of the frame 1 at the position of at least one set of flipping swing slots 101. The limit switch 9 is electrically connected to the transmission mechanism 4, specifically, the limit switch 9 is electrically connected to the third drive member 40. When the first flipping rod 535 or the second flipping rod 536 of the flipping mechanism 5 swings to its limit position, it touches the limit switch 9, triggering a signal to stop the third drive member 40, preventing over-flipping and ensuring that the action is within a safe range, thus achieving safe control of the working process. The automatic stop function avoids mechanical overload and reduces equipment damage; the electrical connection design simplifies control and improves response speed. It solves the shortcomings of manual monitoring and reduces the failure rate. If the third drive member 40 is high-power, the device also includes a relay, with the limit switch 9 electrically connected to the relay, and the relay electrically connected to the third drive member 40, thereby ensuring the contact life of the limit switch 9.

[0058] The figure shows a schematic diagram of a single limit switch 9. Since the flipping mechanism 5 moves synchronously, setting one limit switch 9 can save costs while achieving the required functions of the device. Optionally, there can be two limit switches 9, with one limit switch 9 installed at the position of the flipping swing slot 101 in each group of slots, thus achieving one for backup.

[0059] All the aforementioned bearing assemblies are detachably connected to the fixing rod assembly via bolts, facilitating future maintenance and replacement. Each bearing assembly includes a bearing housing and an angular contact ball bearing. The angular contact ball bearing is installed inside the bearing housing to ensure the coaxiality and stability of the transmission between gears.
