Description

Technical Field

[0001] This invention relates to the field of wire mesh weaving equipment technology, and in particular to a continuous high-strength wire mesh weaving equipment with pre-warping function. Background Technology

[0002] Existing wire mesh weaving equipment requires a warping process before weaving the metal wire mesh. Currently, this process is mostly accomplished using a separate warping machine. This machine primarily winds the wire from the spool onto the warping roller through a series of components, then removes the warping roller and installs it on the wire mesh weaving equipment for weaving. After the wire on the warping roller is woven, it must be removed from the equipment again, and the process is repeated. This method not only consumes a significant amount of manpower and energy during wire mesh weaving, but also results in large production intervals, impacting production efficiency. Furthermore, existing warping equipment typically uses fixed reeds or dividers to guide and separate the warp threads. This makes it difficult to flexibly adjust the spacing between the dividers or reeds according to process requirements. When producing different specifications of metal wire mesh, the required warp density varies, and fixed-spacing dividers cannot meet the production needs of various metal wire mesh varieties and specifications. Summary of the Invention

[0003] The purpose of this invention is to provide a continuous high-strength wire mesh weaving device with pre-warping function, thereby solving the technical problems mentioned in the background art.

[0004] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: This invention discloses a continuous high-strength wire mesh weaving device with pre-warping function, comprising a pay-off frame and a warping device. The pay-off frame has multiple yarn storage cylinders rotatably mounted for supplying warp yarns. The warping device includes a frame, with a warp yarn guiding mechanism at one end and two warping rollers rotatably mounted at the other end. The two warping rollers are spaced apart vertically, and two warping motors are fixedly mounted on the outer side of the frame to drive the rotation of the two warping rollers. The warp yarn guiding mechanism includes a guide frame fixedly mounted on the upper part of the frame, with multiple slides slidably mounted on the guide frame in the horizontal direction. The guide frame also has a warp yarn spacing adjustment mechanism for adjusting the spacing between the slides, and a warp yarn straightening mechanism is fixedly mounted at the bottom of each slide.

[0005] Furthermore, the frame is equipped with two guide rollers that are staggered in height at the position between the wire feeding frame and the guide frame. The wire fed by the wire storage drum passes around the two guide rollers and then enters the guide frame.

[0006] Furthermore, two horizontal guide slides are fixedly arranged at intervals on the guide frame, and each slide has through holes near its upper and lower ends that slide in cooperation with the two guide slides.

[0007] Furthermore, the guide frame has an adjustment plate slidably mounted on the back side of the plurality of carriages in a vertical direction, and the guide frame is provided with a drive assembly for driving the adjustment plate to slide linearly; the adjustment plate is provided with a plurality of adjustment slots spaced apart, the plurality of adjustment slots are distributed in a fan-shaped pattern, and the distance between each pair of adjacent adjustment slots gradually increases from top to bottom; each adjustment slot corresponds to each carriage, and each carriage has a mating post fixedly mounted on the back side that slides in cooperation with the corresponding adjustment slot.

[0008] Furthermore, guide rails are fixedly installed vertically on the two inner side walls of the guide frame, and two guide sliders are symmetrically fixedly installed on both sides of the adjustment plate, which slide in cooperation with the two guide rails respectively.

[0009] Furthermore, the drive assembly includes a crossbeam fixedly disposed on the upper part of the guide frame at one end away from the plurality of carriages, a vertical transmission screw rotatably disposed at the bottom of the crossbeam, and a servo motor for driving the transmission screw to rotate fixedly disposed at the top of the crossbeam; a transmission sleeve threadedly connected to the transmission screw is fixedly disposed on the side of the adjusting plate opposite to the plurality of carriages.

[0010] Furthermore, the side of the adjusting plate opposite to the plurality of carriages is fixedly connected to the outer peripheral wall of the transmission screw sleeve via a connecting block.

[0011] Furthermore, each of the warp straightening mechanisms includes a mounting frame, with a connecting plate fixedly provided at one upper end of the mounting frame for fixed connection with the bottom of the corresponding carriage. Two wheel seats are arranged opposite each other inside the mounting frame, and straightening groove wheels are rotatably provided at the close ends of the two wheel seats, through which the warp passes.

[0012] Furthermore, vertical connecting slide rods are slidably provided on the upper and lower end plates of the mounting frame, and one end of each connecting slide rod located inside the mounting frame is fixedly connected to one of the two wheel seats. A spring is sleeved on each connecting slide rod at the position between the corresponding wheel seat and the end plate of the mounting frame. Limiting heads are fixedly provided on the one end of each connecting slide rod located outside the mounting frame.

[0013] Furthermore, each of the mounting frames has two support seats symmetrically fixed at one end facing the wire feeding frame. A horizontal wire guide tube is fixedly installed between the two support seats. The axis of the wire guide tube is directly opposite the middle of the two straightening groove wheels, and a tapered wire guide hole is opened in the middle of the wire guide tube.

[0014] Compared with the prior art, the beneficial technical effects of the present invention are as follows: This invention employs a dual warping roller cyclic switching working mode. While one warping roller feeds warp yarns to the weaving machine for weaving, the other warping roller simultaneously performs warping processing. The two warping rollers work alternately and seamlessly, eliminating production interruptions caused by the disassembly and replacement of warping rollers between the warping machine and weaving equipment in traditional processes. This continuous operation method not only reduces equipment downtime but also avoids the manpower and time wasted on repeatedly disassembling the warping rollers, significantly improving the production efficiency of metal wire mesh.

[0015] This invention uses a servo motor to drive a transmission screw to rotate, causing the adjustment plate to move vertically. The inclined adjustment slots simultaneously move all the slides horizontally, thus completing the adjustment of all slide spacing in one go. This can meet the process requirements of different specifications of metal wire mesh for warp spacing and enhance the versatility of the equipment.

[0016] Each carriage of this invention is equipped with a warp straightening mechanism at its bottom. This mechanism employs two opposing straightening grooved wheels, with the warp thread passing between the grooves of the two wheels. Under the elastic force of the spring, the two straightening grooved wheels maintain a constant clamping pressure on the warp thread, effectively straightening bent or curled metal warp threads, eliminating residual stress in the warp thread itself. When the straightened warp thread enters the warping roller, the tension is uniform and the arrangement is neat, providing high-quality warp thread raw materials for subsequent weaving processes, which is beneficial to improving the flatness and weaving quality of the metal wire mesh.

[0017] The warp straightening mechanism of the present invention has a lead-in spool with a tapered lead-in hole at the front end. The axis of the lead-in spool is aligned with the middle position of the two straightening groove wheels. When the warp enters the equipment, it first passes through the lead-in hole. The tapered hole structure plays a guiding and centering role, accurately guiding the warp to the working area between the two straightening groove wheels. This effectively avoids problems such as warp deviation, skipping grooves, or tangling during the transmission process, ensuring the stability and reliability of the equipment during long-term operation.

[0020] like Figures 1-5 As shown, a continuous high-strength wire mesh weaving device with pre-warping function includes a pay-off frame 1 and a warping device. Multiple yarn storage cylinders 2 for supplying warp yarns are rotatably mounted on the pay-off frame 1. The warping device includes a frame 3, with a warp yarn guiding mechanism at one end and two warping rollers 4 rotatably mounted at the other end. The two warping rollers 4 are spaced apart vertically, and two warping motors (not shown in the figure) are fixedly mounted on the outer side of the frame 3 to drive the rotation of the two warping rollers 4.

[0021] The warp guiding mechanism includes a guide frame 5 fixedly installed on the upper part of the frame 3. Multiple slides 6 are slidably installed on the guide frame 5 in the horizontal direction. The guide frame 5 is also provided with a warp spacing adjustment mechanism for adjusting the spacing between each slide 6. A warp straightening mechanism is fixedly installed at the bottom of each slide 6.

[0022] In addition, the frame 3 has two guide rollers 7 installed at different heights in a rotatable position between the wire feeding frame 1 and the guide frame 5. The wire fed by the wire storage drum 2 passes around the two guide rollers 7 and enters the guide frame 5, and is then conveyed by the guide frame 5 to one of the warping rollers 4 for warping.

[0023] In operation, this invention first drives one of the warping motors to rotate the corresponding warping roller 4. The metal warp threads fed by the multiple wire storage cylinders 2 on the wire feeding frame 1 are fed to the rotating warping roller 4 through the warp thread guiding mechanism for warping processing. After the warping roller 4 has completed warping, it can feed the processed warp threads to the weaving machine for metal wire mesh weaving. At the same time, another warping motor drives another warping roller 4 to rotate, and the metal warp threads are fed to the other warping roller 4 through the warp thread guiding mechanism for warping processing. That is, the two warping rollers 4 cycle through the working mode of warping processing and feeding metal warp threads to the weaving machine, which can realize continuous operation of warping processing and weaving frame weaving, thereby reducing labor input and improving the production efficiency of metal wire mesh.

[0024] In this embodiment, two horizontal guide slide rods 8 are fixedly installed at intervals on the guide frame 5. Each slide 6 has through holes near its upper and lower ends that slide in cooperation with the two guide slide rods 8, thereby allowing multiple slides 6 to be slidably installed on the guide frame 5.

[0025] The guide frame 5 has an adjusting plate 9 slidably mounted vertically on the back side of the multiple slides 6. Specifically, guide rails 10 are fixedly mounted vertically on the two inner sidewalls of the guide frame 5, and two guide sliders 11, which slide and cooperate with the two guide rails 10, are symmetrically fixedly mounted on both sides of the adjusting plate 9. The guide frame is provided with a drive assembly for driving the adjusting plate to slide linearly. The drive assembly includes a crossbeam 12 fixedly mounted on the upper part of the guide frame 5 away from the multiple slides 6. A vertical transmission screw 13 is rotatably mounted on the bottom of the crossbeam 12, and a servo motor 14 for driving the transmission screw 13 to rotate is fixedly mounted on the top of the crossbeam 12. A transmission sleeve 15 threadedly connected to the transmission screw 13 is fixedly connected to the side of the adjusting plate 9 away from the multiple slides 6. The side of the adjusting plate 9 away from the multiple slides is fixedly connected to the outer peripheral wall of the transmission sleeve 15 through a connecting block 16.

[0026] The adjusting plate 9 is provided with multiple adjusting grooves 17 spaced apart. These grooves are arranged in a fan-shaped pattern, with the distance between adjacent grooves gradually increasing from top to bottom. Each adjusting groove 17 corresponds to a slide 6, and each slide 6 has a fixed mating post 18 that slides in slidable with the corresponding adjusting groove 17. When the servo motor 14 drives the transmission screw 13 to rotate, the transmission sleeve 15 remains threadedly connected to the transmission screw 13, converting the rotational motion of the transmission screw 13 into linear motion of the adjusting plate 9 in the vertical direction. As the adjusting plate 9 moves linearly in the vertical direction, the mating post 18 on each slide 6 slides in slidable with the adjusting groove 17 on the adjusting plate 9. The adjusting plate 9 then moves horizontally by tilting the adjusting groove 17, causing the mating post 18 and the corresponding slide 6 to move in the horizontal direction. This changes the distance between adjacent slides 6, thus adjusting the spacing of the metal warp wire guides to meet the weaving requirements of different specifications of metal wire mesh.

[0027] In this embodiment, each of the warp straightening mechanisms includes a mounting frame 19. A connecting plate 20 for fixed connection to the bottom of the corresponding carriage 6 is fixedly disposed at one upper end of the mounting frame 19. Two wheel seats 21 are mounted opposite each other inside the mounting frame 20. Straightening grooved wheels 22 are rotatably mounted at the adjacent ends of the two wheel seats 21. The warp threads pass through the grooves of the two straightening grooved wheels 22, thereby straightening the warp threads that are bent by the two oppositely arranged straightening grooved wheels 22.

[0028] As a further improvement to this embodiment, vertical connecting slide rods 23 are slidably mounted on the upper and lower end plates of the mounting frame 19, respectively. One end of each connecting slide rod 23 located inside the mounting frame 19 is fixedly connected to one of the two wheel seats 21. A spring 24 is fitted onto each connecting slide rod 21 at the portion located between the corresponding wheel seat 21 and the end plate of the mounting frame 19. Limit heads 25 are fixedly mounted on the outer ends of each connecting slide rod 23. Under the action of the springs 24 on the connecting slide rods 23, the two wheel seats 21 and the straightening groove wheel 22 will have a relative movement tendency. Thus, the two straightening groove wheels 22 jointly apply straightening pressure to the warp yarn, ensuring the straightening effect of the warp yarn and meeting the straightening requirements for warp yarns of different outer diameters.

[0029] In addition, each of the mounting frames 19 is symmetrically fixed with two support seats 26 at one end facing the wire feeding frame 1. A horizontal wire guide tube 27 is fixedly connected between the two support seats 26. The axis of the wire guide tube 27 is directly opposite the middle of the two straightening groove rollers 22, and a conical wire guide hole 28 is opened in the middle of the wire guide tube 27. The warp wire can be gradually guided to the middle of the two straightening groove rollers 22 through the wire guide hole 28 of the wire guide tube 27, so as to avoid misalignment during the warp wire transmission process.

[0030] The embodiments described above are merely preferred embodiments of the present invention and are not intended to limit the scope of the present invention. Various modifications and improvements made by those skilled in the art to the technical solutions of the present invention without departing from the spirit of the present invention should fall within the protection scope defined by the claims of the present invention.
