Description

Technical Field

[0001] This utility model relates to the field of gabion mesh weaving machine technology, and in particular to a synchronous drive mechanism for a gabion mesh weaving machine. Background Technology

[0002] Gabion mesh weaving machines, also known as hexagonal mesh weaving machines or gabion mesh weaving machines, work by using a series of coordinated mechanical movements to weave metal wires, such as galvanized steel wire or PVC-coated wire, into a hexagonal mesh structure. During the weaving process, both the warp and weft wires exert tension on the machine's moving components. This tension causes a rotational difference between the upper and lower cooperating weaving components as the machine rotates and winds. This rotational difference affects the weaving quality of the gabion mesh and also causes significant wear and tear on the equipment.

[0003] Utility model patent CN 220347089U discloses a gabion mesh weaving device, in which a rack driving the half-gears of the weaving components is driven by a rotating assembly. However, in this patent's technical solution, the core part of the rotating assembly, the third connecting shaft, uses two half-shafts coaxially assembled together. That is, there is a gap between the first shaft segment and the second shaft segment, and a second slip assembly is assembled there. Theoretically, the second slip assembly can adjust the rotational difference between the upper and lower weaving components. In reality, this half-shaft transmission, and the influence of the fit clearances between various parts, will inevitably increase the rotational deviation between the upper and lower weaving components. Moreover, the screw set screw structure of the second slip assembly is prone to damage after repeated impacts, leading to an increased failure rate.

[0004] Therefore, it is necessary to develop a new synchronous drive mechanism for gabion mesh weaving machines to address the above-mentioned shortcomings, which has become an urgent problem for those skilled in the art to solve. Utility Model Content

[0005] The purpose of this utility model is to provide a synchronous drive mechanism for a gabion mesh weaving machine, which uses a through shaft to synchronously drive the upper and lower rotation drive components, thereby improving the synchronization performance of the upper and lower rotation drive components.

[0006] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0007] This utility model discloses a synchronous drive mechanism for a gabion mesh weaving machine, used to drive the twisting wheel of the gabion mesh weaving machine to rotate. It includes a support frame, a drive unit, and upper and lower sets of rotation drive components. The rotation drive components include a drive rack, a gear support frame, a pinion, a drive gear, and a working rack. It also includes a main shaft and a bearing seat. The two drive gears are coaxially mounted at both ends of the main shaft. The drive unit is coaxially connected to the top end of the main shaft through a coupling. The bearing seat is mounted on the upright plate of the support frame through a bearing seat frame, and the bearing seat supports the middle part of the main shaft.

[0008] Furthermore, the rotation drive assembly also includes a slide plate, the drive rack is mounted on the slide plate by screws, and the working rack is mounted on the side of the slide plate facing the main unit of the equipment by screws; the bottom surface of the slide plate is provided with a plurality of bottom guide sliders, which slide on two horizontal support plates of the support frame; the inner side wall of the gear support frame is provided with an inner guide slider, and the slide plate and the drive rack slide on the inner guide slider away from the side wall of the pinion.

[0009] Furthermore, both the bottom guide slider and the inner guide slider are made of polytetrafluoroethylene sheet.

[0010] Furthermore, the two ends of the side wall of the gear support frame are connected to baffles by screws, and the baffles limit the end face of the inner guide slider.

[0011] Furthermore, it also includes a fine-tuning component disposed between the slide plate and the working rack, the fine-tuning component being capable of fine-tuning the front and rear positions of the working rack.

[0012] Furthermore, the fine-tuning assembly includes an adapter, an adjusting screw, a fixing block, and a pressure plate. The adapter is mounted on the rear side wall of the end of the working rack by screws. The bottoms of the two fixing blocks are fixedly connected to the top surface of the slide plate. The adjusting screw is threadedly connected to the coaxial threaded hole of the two fixing blocks. The protruding head of the adapter has a coaxial through hole at the position of the adjusting screw. A lock nut is threadedly connected to the adjusting screw, and the lock nut abuts against the side wall of the protruding head of the adapter. The pressure plate presses against the top surfaces of the fixing blocks and the working rack.

[0013] Furthermore, the fine-tuning component also includes a clamping plate, which is clamped onto the tooth surface of the working rack in conjunction with the adapter.

[0014] Furthermore, the number of lock nuts on the adjusting screw is four, with two lock nuts tightly fastened to the side wall of the adapter protrusion.

[0015] Furthermore, the number of the fine-tuning components is two sets, and each set is disposed on one of the slide plates in one of the two sets of rotation drive components.

[0016] Compared with the prior art, the beneficial technical effects of this utility model are as follows:

[0017] This utility model discloses a synchronous drive mechanism for a gabion mesh weaving machine. By employing a single through-shaft main shaft to synchronously drive the drive gears of the upper and lower rotating drive components, compared to a split-shaft method, transmission backlash is reduced, and differential movement between the upper and lower rotating drive components is eliminated. The central portion of the main shaft is supported by a bearing housing, simplifying the support method and ensuring stable operation. This synchronous drive mechanism for a gabion mesh weaving machine, using a through-shaft to synchronously drive the upper and lower rotating drive components, improves the synchronization performance of the upper and lower rotating drive components.

[0018] Furthermore, this invention employs bottom and inner guide sliders to guide sliding on the inner walls of the horizontal support plate and gear support frame of the support frame, increasing the guiding area and significantly reducing friction loss. Moreover, the use of PTFE sheet for the guide sliders significantly reduces noise during operation. By adding a fine-tuning component to one of the slide plates in each of the two sets of rotary drive assemblies, the fore-and-aft position of one working rack in each set of rotary drive assemblies can be finely adjusted. Fine-tuning the fore-and-aft position of the working rack allows for fine-tuning the initial position of the thread-tightening wheel, ensuring precise alignment between the thread-tightening wheel's split surface and the pull arm's slot. Through the cooperation of the adapter and adjusting screw, the axial position of the adapter's through-hole on the adjusting screw can be adjusted, thereby achieving fine-tuning of the working rack's fore-and-aft position. By pressing a pressure plate against the top surface of the fixing block and the working rack, the adjusted working rack can be finally tightened and fixed. By using a clamping plate in conjunction with the adapter to clamp and fix it to the tooth surface of the working rack, the adapter can be stably and securely installed. Attached Figure Description

[0025] The core of this utility model is to provide a synchronous drive mechanism for a gabion mesh weaving machine, which uses a through shaft to synchronously drive the upper and lower rotation drive components, thereby improving the synchronization performance of the upper and lower rotation drive components.

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of the present utility model, and not all of them. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present utility model. In the following detailed description of the accompanying drawings, the descriptions of top, bottom, left, and right are all relative to the accompanying drawings and should not be construed as limiting the present utility model.

[0027] Refer to the attached diagram. Figure 1 This is a three-dimensional structural diagram of the synchronous drive mechanism of the gabion mesh weaving machine of this utility model; Figure 2 for Figure 1 A schematic diagram of the three-dimensional structure after removing the top gear support frame and drive bracket; Figure 3 This is a three-dimensional structural diagram of the present invention from another angle; Figure 4 for Figure 1 A magnified schematic diagram of the structure of part I in the middle.

[0028] In one specific implementation, such as Figures 1-4 As shown, a synchronous drive mechanism for a gabion mesh weaving machine is used to drive the twisting wheel of the gabion mesh weaving machine to rotate. It includes a support frame 1, a drive unit 7, and upper and lower sets of rotation drive components. The rotation drive components include a drive rack 2, a gear support frame 3, a pinion 4, a drive gear 5, and a working rack 11. The synchronous drive mechanism of this gabion mesh weaving machine also includes a main shaft 6 and a bearing seat 12. Two drive gears 5 are coaxially mounted at both ends of the same main shaft 6. The drive unit 7 is coaxially connected to the top of the main shaft 6 via a coupling. The bearing seat 12 is mounted on the upright plate of the support frame 1 via a bearing seat bracket 101, and the bearing seat 12 supports the middle part of the main shaft 6.

[0029] The rotation drive assembly described in this invention adopts a structure consistent with existing technologies. The drive gear 5 drives four pinions 4 to rotate, and the pinions 4 drive the drive rack 2 to slide back and forth. This part of the structure will not be described in detail.

[0030] Specifically, such as Figure 1 and Figure 3 As shown, the drive unit 7 specifically adopts a hydraulic motor or a geared motor. The drive unit 7 is mounted on the gear support frame 3 of the rotation drive assembly described above via a drive bracket 10. The drive bracket 10 is an inverted U-shaped plate frame, which is installed at both ends of the top plate of the gear support frame 3 by screws.

[0031] By employing a single through-shaft main shaft 6 to synchronously drive the drive gears 5 of the upper and lower rotary drive components, the transmission backlash is reduced compared to a split-shaft method, and differential movement between the upper and lower rotary drive components is eliminated. The bearing housing 12 supports the middle portion of the main shaft 6, simplifying the support method and ensuring stable operation. This utility model's synchronous drive mechanism for a gabion mesh weaving machine uses a through-shaft to synchronously drive the upper and lower rotary drive components, improving their synchronization performance.

[0032] In one specific embodiment of this utility model, such as Figures 1-4 As shown, the rotation drive assembly also includes a slide plate 8. A drive rack 2 is mounted on the slide plate 8 with screws, and a working rack 11 is mounted on the side of the slide plate 8 facing the main machine with screws. The working rack 11 directly drives the twisting wheel of the braiding machine body. The drive rack 2 and the slide plate 8 are confined to the inside of the gear support frame 3. Multiple bottom guide sliders 801 are provided on the bottom surface of the slide plate 8, and these sliders are arranged at equal intervals. The bottom guide sliders 801 slide on two horizontal support plates of the support frame 1. An inner guide slider 301 is provided on the inner side wall of the gear support frame 3, and the slide plate 8 and the drive rack 2, facing away from the side wall of the pinion 4, slide guided by the inner guide slider 301.

[0033] Specifically, such as Figures 1-4 As shown, both the bottom guide slider 801 and the inner guide slider 301 are made of polytetrafluoroethylene (PTFE) sheet. PTFE material has good self-lubricating properties, which can significantly reduce wear.

[0034] Specifically, such as Figure 3 and Figure 4 As shown, baffles 302 are screwed to both ends of the side wall of the gear support frame 3, and the baffles 302 limit the end face of the inner guide slider 301. The end face of the baffles 302 does not contact the back of the slide plate 8 and the drive rack 2.

[0035] Compared to the existing technology that uses guide rail slots to limit and guide the drive rack 2, this invention uses a bottom guide slider 801 and an inner guide slider 301 to guide and slide on the horizontal support plate of the support frame 1 and the inner sidewall of the gear support frame 3, which increases the guiding area and significantly reduces friction loss. Furthermore, using polytetrafluoroethylene (PTFE) sheet to make the guide sliders can significantly reduce noise during operation.

[0036] In one specific embodiment of this utility model, such as Figures 1-4 As shown, the synchronous drive mechanism of the gabion mesh weaving machine of this utility model also includes a fine-tuning component 9, which is disposed between the slide plate 8 and the working rack 11. The fine-tuning component 9 can fine-tune the front and rear positions of the working rack 11.

[0037] Specifically, such as Figure 1 and Figure 2 As shown, there are two sets of fine-tuning components 9, each set on a slide plate 8 in one of the two sets of rotation drive components.

[0038] By adding a fine-tuning component 9 to one of the slide plates 8 in the two sets of rotary drive components, the front-to-back position of one working rack 11 in each set of rotary drive components can be finely adjusted. Fine-tuning the front-to-back position of the working rack 11 can fine-tune the initial position of the thread-tightening wheel, so that the split surface of the thread-tightening wheel and the slot of the pull arm are precisely aligned.

[0039] In one specific embodiment of this utility model, such as Figure 4 As shown, the fine-tuning component 9 includes an adapter 901, an adjusting screw 902, a fixing block 903, and a pressure plate 904. The adapter 901 is mounted on the rear side wall of the end of the working rack 11 by screws. The bottoms of the two fixing blocks 903 are fixedly connected to the top surface of the slide plate 8. The adjusting screw 902 is threaded into the coaxial threaded hole of the two fixing blocks 903. The protruding head of the adapter 901 has a coaxial through hole at the position of the adjusting screw 902, through which the adjusting screw 902 coaxially passes. The length direction of the adjusting screw 902 is parallel to the working rack 11. A lock nut is threaded onto the adjusting screw 902, and the lock nut abuts against the side wall of the protruding head of the adapter 901. The pressure plate 904 presses against the top surfaces of the fixing block 903 and the working rack 11, and the pressure plate 904 is fixed by screws connected to the threaded hole on the top surface of the slide plate 8.

[0040] Specifically, such as Figure 4 As shown, the fine-tuning component 9 also includes a clamping plate 905, which is clamped onto the tooth surface of the working rack 11 in conjunction with the adapter 901.

[0041] Specifically, such as Figure 4 As shown, the number of lock nuts on the adjusting screw 902 is four, with two lock nuts tightly fastened to the side wall of the protruding head of the adapter 901.

[0042] By cooperating with the adapter 901 and the adjusting screw 902, the axial position of the working rack 11 can be finely adjusted by adjusting the axial position of the through hole of the adapter 901 on the adjusting screw 902. The adjusted working rack 11 can be finally tightened and fixed by pressing the pressure plate 904 onto the top surface of the fixing block 903 and the working rack 11. The adapter 901 can be stably and securely installed by clamping the clamping plate 905 onto the tooth surface of the working rack 11 in conjunction with the adapter 901.

[0043] The working principle of the synchronous drive mechanism of this utility model gabion mesh weaving machine is as follows: The drive unit 7 drives the main shaft 6 to rotate through the coupling. The main shaft 6 drives the drive gears 5 at both ends to rotate synchronously. The drive gears 5 drive the four peripheral small gears 4 to rotate synchronously and transmit power to the drive rack 2. The drive rack 2 drives the slide plate 8 to move linearly in the guide direction. Because the two drive racks 2 are above and below the small gears 4 rotating in the same direction, the two drive racks 2 move synchronously in opposite directions. The slide plate 8 drives the working rack 11 to move linearly in opposite directions, thereby driving the twisting wheel to rotate. When the twisting wheel split surface and the pull arm are misaligned, the position of the lock nut on the screw 902 can be adjusted, thereby adjusting the position of the adapter 901, so that the working rack 11, which is fixedly connected to the adapter 901, moves back and forth to compensate for the misalignment. After adjustment, the fastening screws of the pressure plate 904 are tightened again.

[0044] In summary, the synchronous drive mechanism of this gabion mesh weaving machine uses a single through-shaft main shaft 6 to synchronously drive the drive gears 5 of the upper and lower rotating drive components. Compared to the split-shaft method, this reduces transmission clearance and eliminates differential movement between the upper and lower rotating drive components. The bearing seat 12 supports the middle of the main shaft 6, simplifying the support method and ensuring stable operation. The synchronous drive mechanism of this gabion mesh weaving machine uses a through-shaft to synchronously drive the upper and lower rotating drive components, improving their synchronization performance. Furthermore, the bottom guide slider 801 and inner guide slider 301 guide and slide on the horizontal support plate of the support frame 1 and the inner wall of the gear support frame 3, increasing the guiding area and significantly reducing friction loss. Moreover, using polytetrafluoroethylene (PTFE) sheet for the guide sliders significantly reduces noise during operation. By adding a fine-tuning component 9 to one of the slide plates 8 in each of the two sets of rotating drive components, the front-to-back position of one working rack 11 in each set of rotating drive components can be finely adjusted. Fine-tuning the front-to-back position of the working rack 11 allows for precise adjustment of the initial position of the thread-tightening wheel, ensuring accurate alignment between the thread-tightening wheel's split surface and the pull arm's slot. Through the cooperation of the adapter 901 and the adjusting screw 902, the axial position of the through hole in the adapter 901 on the adjusting screw 902 can be adjusted, thereby achieving fine-tuning of the front-to-back position of the working rack 11. By pressing the pressure plate 904 against the top surface of the fixing block 903 and the working rack 11, the adjusted working rack 11 can be finally tightened and fixed. By using the clamping plate 905 in conjunction with the adapter 901 to clamp and fix it onto the tooth surface of the working rack 11, the adapter 901 can be stably and securely installed.

[0045] The embodiments described above are merely preferred embodiments of the present utility model and are not intended to limit the scope of the present utility model. Various modifications and improvements made to the technical solutions of the present utility model by those skilled in the art without departing from the spirit of the present utility model should fall within the protection scope defined by the claims of the present utility model.
