Description

Technical Field

[0001] This invention relates to the field of grid weaving technology, and more particularly to a grid horizontal and vertical weaving device. Background Technology

[0002] In modern engineering construction, agricultural production, environmental management, and many other fields, geogrids, as a material with good structural strength and permeability, are widely used in roadbed reinforcement, soil and water conservation, and fencing protection. In the production and manufacturing of geogrids, the weaving process is a key factor determining its performance and quality, and the quality of the horizontal and vertical weaving directly affects the tensile strength, stability, and service life of the product. Grid weaving is mostly accomplished using grid horizontal and vertical weaving machines. These machines consist of a pay-off mechanism, a wire feeding and guiding mechanism, a weaving execution mechanism, a traction and winding mechanism, and a control system. Their working principle is as follows: First, the warp and weft pay-off units of the pay-off mechanism output warp and weft threads respectively, and their respective tension adjustment devices adjust the grid tension in real time to ensure the grid is in a stable tension state. Next, the wire feeding and guiding mechanism takes effect; the warp threads are arranged into an evenly spaced parallel array by positioning combs, while the weft threads, guided by the guiding components, wait on one side of the warp array, preparing for weaving. After preparation, the control system drives the weaving actuator. The warp opening and closing device raises and lowers a portion of the warp in a regular pattern to form an interlaced weave. The weft insertion device carries the weft through the weave quickly to complete one interlacing. Then, the warp opening and closing device switches to form a new weave, and the weft insertion device moves in the opposite direction to complete the second interlacing. Through reciprocating motion, the warp and weft are interlaced. After each row of interlacing is completed, the traction roller of the traction winding mechanism moves the grid forward by one grid width. The winding roller rotates synchronously to wind the finished grid into a roll, ultimately forming a grid product with a stable structure.

[0003] However, after the horizontal and vertical grid weaving machine completes the weaving of several grids, the woven grids pass through the heat-pressing head in sequence. The heat-pressing head presses and fixes the horizontal grids onto multiple rows of vertical grids, ensuring a tight bond between the two. After heat pressing, the grids are conveyed to the winding stage. At this time, the pressure roller on one side of the winding roller applies pressure to the grids to maintain their tension during the winding process, ensuring a neat and tight winding. However, when the grid material wound on the unwinding mechanism is completely wound by the traction winding mechanism, that is, after the last section of grid passes through the pressure roller, the contact between the pressure roller and the grid disappears, and the tension on the woven grid also disappears. At this time, due to inertia or program settings, the traction winding mechanism continues to wind the woven grids, which causes the remaining grids on the winding device to become loose when they lose their tension constraint, affecting the storage and subsequent use of the finished grids. Therefore, it is necessary to design a horizontal and vertical grid weaving device.

[0004] It should be noted that the information disclosed in this background section is only for understanding the background technology of this application concept, and therefore may include information that does not constitute prior art. Summary of the Invention

[0005] This invention provides a grid horizontal and vertical weaving device to solve the problem that when the last section of the grid passes the pressure roller during winding, the tension disappears, but the traction continues to wind, resulting in loose and messy grid winding, which affects storage and use.

[0006] The present invention adopts the following technical solution: a grid horizontal and vertical weaving device.

[0009] Furthermore, the reinforcing part includes a connecting piece fixed to one side of the upper clamping plate. The connecting piece has a concave structure, and spherical protrusions are connected to both ends of the inner wall of the connecting piece by springs. Partial positions of the spherical protrusions are embedded in the inner wall of the connecting piece. A fastener is adapted to be installed on one side of the lower clamping plate and engages between the two sets of spherical protrusions. The shape of the fastener is adapted to the concave structure of the connecting piece and the spherical protrusions. In the initial state, there is a small gap between the fastener and the connecting piece.

[0010] Furthermore, the reset part includes two sets of reset rods fixed on the extension frame. A sliding pin block is slidably disposed on the reset rod. A pin groove is adapted to be opened in the reset rod for the sliding pin block to slide. A protrusion is provided on both sides of the sliding pin block. The pin groove is connected to a side groove for the protrusion to slide on both sides. The side groove cooperates with the protrusion. A vertically arranged sliding rod is fixed on the pulley. One end of the sliding rod movably passes through a sliding pin block. A waist groove is opened on the pin groove to allow the sliding rod to move. The waist groove is adapted to the movement of the sliding rod and provides a certain amount of movement. One end of the sliding rod is provided with an anti-detachment step. A buffer spring three is connected between the anti-detachment step and the upper surface of the sliding pin block. The buffer spring three is sleeved on the sliding rod. A spring two is connected between the sliding pin block and one end of the inner wall of the pin groove. The spring two is a damping spring with certain damping characteristics.

[0011] Furthermore, the unwinding mechanism includes a limiting frame, which has a concave structure. Multiple sets of dividing rods are evenly distributed between the limiting frames. An overlapping frame is installed on the side of each adjacent dividing rod that is close to each other. The overlapping frame has an overlapping end. A winding wheel is placed on the overlapping end of two sets of overlapping frames. The winding wheel has a roller shaft, and the winding wheel is overlapped on the overlapping end through the roller shaft. Two sets of horizontal frames are provided on one side of the overlapping frame, forming two sets of horizontal ends. Three sets of pressure limiting parts are provided between the two sets of horizontal ends of the horizontal frame. The pressure limiting parts include a support plate provided on the horizontal end. The support plate is horizontal and fixed parallel to the horizontal end. A U-shaped sleeve is fixed on the support plate by fasteners. The opening of the U-shaped sleeve faces the horizontal end and forms a clamping and fixing end with the support plate. A pressure holding rod is connected between the two sets of opposite fixing ends. A guide frame is fixed on the side of the horizontal frame. Round rods extend downward from the bottom ends of both sides of the guide frame. The two ends of the round rods are fixed to the bottom of the guide frame by supports.

[0012] Furthermore, the wire feeding guide mechanism includes a device frame disposed on one side of the guide frame, a guide part disposed on the device frame, the guide part including a base fixed on the device frame, an extension frame fixed on the base near both sides, a crossbar connecting one end of the two sets of extension frames, the crossbar horizontally spanning the top of the extension frame, connecting the two extension frames into one unit, wire threading blocks distributed at intervals on the crossbar, and through holes arranged vertically on the wire threading blocks.

[0013] Furthermore, a wire guide is fixed on the base platform and on one side of the first crossbar. The wire guide includes a base frame with a concave structure fixed on the base platform. The base frame has an upward opening. The second crossbar is supported on the base frame by two sets of I-shaped frames. The I-shaped frames include clamping blocks arranged vertically. The clamping blocks are mating block structures. A screw connects the upper and lower clamping blocks. The two ends of the second crossbar are respectively located between the two sets of clamping blocks of the I-shaped frame. A gap is formed between the second crossbars. The grid passing through the hole at the lower end of the wire guide block passes through the gap.

[0014] Furthermore, the side of the second crossbar is provided with a threading part for inserting the transverse grid into the upper and lower vertical grids. The threading part includes a concave frame two fixed to the side of the second crossbar. The opening of the concave frame two faces the second crossbar. A lead screw is installed on the concave frame two through a bearing. The lead screw is arranged along the length direction of the second crossbar.

[0015] Furthermore, auxiliary rollers are installed between the inner walls of the extension frame, and a rotating shaft is installed between the inner walls of the extension frame via bearings. Adjusting rods are fixedly sleeved near both ends of the rotating shaft, and a pressure roller is fixed between the two sets of adjusting rods. The pressure roller provides tension for the grid. Two cylinders are fixed on both sides of the inner wall of the equipment frame. The telescopic end of the cylinder is movably connected to the adjusting rod. The cylinder can drive the adjusting rod to rotate, so that the horizontal and vertical grids first pass over the bottom surface of the pressure roller, and then pass over the upper surface of the auxiliary roller. At this time, the upward slope formed by the horizontal and vertical grids is defined as the first slope, and the second slope is higher than the first slope.

[0016] The above-described at least one technical solution adopted in the embodiments of the present invention can achieve the following beneficial effects: A grid weaving device, integrating an unwinding mechanism, a wire feeding and guiding mechanism, a heat-sealing mechanism, a pressing mechanism, and a tensioning mechanism, effectively solves the problem of loose grid at the winding end of traditional equipment. The clamping part of the tensioning mechanism, in conjunction with a reinforcing part, can tightly clamp the grid through spring force and a mechanical locking structure when the last section of grid passes the pressure roller and the tension disappears, continuously providing stable tension. The reset part ensures smooth reset of the clamping part after the operation is completed, guaranteeing the stability of cyclic operation. Simultaneously, the cooperation of these mechanisms forms a closed-loop control from raw material unwinding to winding, ensuring weaving and heat-sealing accuracy while the dynamic tension compensation of the tensioning mechanism prevents loosening at the winding end due to tension loss, improving the winding quality of the finished grid and facilitating storage and subsequent use.

[0019] To further illustrate the technical means and effects of the present invention in achieving its intended purpose, the following detailed description of the specific implementation methods, structures, features, and effects of the present invention, in conjunction with the accompanying drawings and preferred embodiments, is provided below.

[0020] The technical solutions provided by the various embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0021] Example 1: Refer to Figures 1 to 3 As shown, an embodiment of the present invention provides a grid weaving device, including an unwinding mechanism 1, a wire feeding and guiding mechanism 2, a hot-pressing mechanism 3, a pressing mechanism 4, a tensioning mechanism 5, and a winding mechanism 6; The unwinding mechanism 1 includes a limiting frame 11, which has a concave structure and multiple sets of dividing rods 12 are evenly distributed between the limiting frames 11 to divide the internal space of the limiting frame 11 into multiple independent areas. An overlapping frame 13 is fixedly installed on the side of the adjacent dividing rods 12 that is close to each other. The overlapping frame 13 is an inverted "V" shape and has an overlapping end 131. A winding wheel 14 is placed on the overlapping end 131 of the two sets of overlapping frames 13. The winding wheel 14 has a roller shaft and is overlapped on the overlapping end 131 through the roller shaft, which facilitates quick loading and unloading and can maintain stable rotation during unwinding. Furthermore, two sets of horizontal frames 15 are provided on one side of the overlapping frame 13. The horizontal frame 15 is an inverted "F" shaped structure. This structure allows the horizontal frame 15 to naturally form two sets of horizontal ends. Three sets of pressure limiting parts are provided between the two sets of horizontal ends of the horizontal frame 15. The pressure limiting part includes a support plate 151 provided on the horizontal end. The support plate 151 is in the shape of a horizontal plate and is fixed parallel to the horizontal end. A U-shaped sleeve 152 is fixed on the support plate 151 by fasteners. The opening of the U-shaped sleeve 152 faces the horizontal end and forms a clamping and fixing end with the support plate 151. A pressure holding rod 153 is connected between the two sets of opposite fixing ends. The pressure holding rod 153 adopts a smooth cylindrical structure, which can reduce the wear on the surface of the grid. It should be noted that one set of pressure limiting parts is set on the bottom surface of the upper horizontal end of the cross frame 15, and the other two sets of pressure limiting parts are set side by side on the surface of the lower horizontal end of the cross frame 15, forming a staggered layout of the three sets of pressure limiting parts. After multiple sets of single grid raw materials are drawn out from the winding reel 14, they first pass upward through the gap between the two sets of pressure limiting parts at the lower end, and then go downward around the pressure holding rod 153 of the upper pressure limiting part, forming an "S" shaped material feeding path; This layout allows for multi-stage pressure control of the grid from different positions and heights. When the grid material passes through the pressure rod 153, a stable tension is formed by gravity and the contact pressure of the pressure rod 153. Even if the diameter of the winding wheel 14 gradually decreases during the unwinding process, the tension change can be compensated through the path design, and the tension can be continuously and stably applied to the grid, avoiding the phenomenon of sudden loosening and tightening during grid unwinding, and effectively ensuring the accuracy of subsequent wire feeding guidance and weaving processes.

[0022] Meanwhile, a guide frame 16 is fixed to the side of the cross frame 15. The guide frame 16 is generally long and flat, and is arranged parallel to the length of the cross frame 15. Round rods 161 extend downwards from the bottom ends of both sides of the guide frame 16. The round rods 161 have a cylindrical structure and are fixed to the bottom of the guide frame 16 at both ends by supports, and their surfaces are smoothed. After the tension of the bar screen material is adjusted in the pressure limiting section, it enters the area of ​​the guide frame 16, at which point the round rods 161 are suitable for contacting the bar screen surface. On the one hand, the cylindrical contour of the round rods 161 is used to flexibly guide the bar screen.

[0023] In order to carry out the next weaving operation on the unwound grid, such as Figures 4-7 As shown, a wire feeding guide mechanism 2 is provided on one side of the guide frame 16. The wire feeding guide mechanism 2 includes an equipment frame 21 provided on one side of the guide frame 16. The equipment frame 21 is securely assembled on the equipment body by fasteners. A guide part is provided on the equipment frame 21. The guide part is used to guide the multiple grids being unwound to move up and down, so as to facilitate the subsequent transverse grid insertion operation. The guide part includes a base platform 22 fixed on the equipment frame 21. An extension frame 23 is fixed on the base platform 22 near the two sides. The extension frame 23 is a plate-shaped structure that extends vertically upward. It is fixed vertically to the base platform 22 and provides installation support for the crossbar 24. A crossbar 24 connects one end of each of the two sets of extension frames 23. The crossbar 24 spans horizontally across the top of the extension frames 23, connecting the two extension frames 23 into a single unit and enhancing the overall structural stability of the guide section. Wire-passing blocks 25 are spaced apart on the crossbar 24 and are fixed to the side of the crossbar 24 with fasteners, facilitating adjustment and replacement according to the number of grids and spacing requirements. Simultaneously, the wire-passing blocks 25 have vertically arranged through holes 251. The diameter of the through holes 251 is adapted to the size of a single grid, allowing the grid to pass through smoothly. The through holes 251 provide initial positioning of the grids, guiding each grid along a predetermined path to the subsequent guide section. Meanwhile, a guide wire part is fixed on the base 22 and on one side of the first crossbar 24. The guide wire part includes a concave base frame 26 fixed on the base 22. The base frame 26 has an upward opening to provide installation space for the upper components. The second crossbar 29 is supported on the base frame 26 by two sets of I-beams. The I-beams are the key structures to ensure the stable installation of the second crossbar 29. The I-beams include upper and lower clamping blocks 27. The clamping blocks 27 are mating block structures. A screw 28 connects the upper and lower clamping blocks 27. By turning the screw 28, the gap between the clamping blocks 27 can be adjusted to achieve clamping and fixing of the second crossbar 29 and fine adjustment of its height, which can easily adapt to grids with different thicknesses and orientation requirements. Meanwhile, the two ends of the second crossbar 29 are respectively located between the two sets of clamping blocks 27 of the I-beam frame. With the clamping force of the clamping blocks 27, it is firmly installed above the base frame 26, and the second crossbar 29 forms a gap 210. The grid passing through the lower end of the threading block 25 through the hole 251 passes through the gap 210. The spatial constraint of the gap 210 keeps this part of the grid in the lower layer direction. The grid passing through the upper end of the threading block 25 through the hole 251 passes through the upper surface of the second crossbar 29. Relying on the support of the upper surface of the second crossbar 29, the grid keeps the grid in the upper layer direction. Through this layered guidance method, multiple grids are combed into an orderly array, creating conditions for the subsequent horizontal grid weaving operation, allowing the horizontal grids to be accurately inserted between the upper and lower grids, ensuring weaving accuracy and grid product quality.

[0024] Furthermore, a threading part is provided on the side of the second crossbar 29 to pass through the horizontal grid to the upper and lower vertical grids. The threading part includes a concave frame 217 fixed on the side of the second crossbar 29. The opening of the concave frame 217 faces the second crossbar 29, and a lead screw 218 is installed on the concave frame 217 through bearings. The lead screw 218 is arranged along the length of the second crossbar 29, and its two ends are rotatably connected to the concave frame 217 through bearings to ensure smooth rotation. A sliding seat 220 is threaded onto the lead screw 218. Guide rods 221 are fixed on both sides of the lead screw 218 on the concave frame 217, with the guide rods 221 parallel to the lead screw 218. The sliding seat 220 is slidably sleeved on both sets of guide rods 221, ensuring smooth linear movement of the sliding seat 220. A motor 219 is fixed to one end of the concave frame 217, and the output shaft of the motor 219 is rigidly connected to one end of the lead screw 218 via a coupling, driving the lead screw 218 to rotate in both directions. A pneumatic clamp 222 is provided on the sliding seat 220, and an opening slot 291 for the transverse grid to pass through is provided on the side of the crossbar 29. The clamp of the pneumatic clamp 222 faces the slot 291, forming an alignment for clamping and insertion. It should be noted that, in the initial state, the pneumatic clamp 222 is located at one end of the crossbar 29 under the drive of the sliding seat 220. When it is necessary to insert the transverse grid between the upper and lower vertical grids, the transverse grid is manually held and one end is aligned with the clamping mouth of the pneumatic clamp 222. The pneumatic clamp 222 is then activated to close its clamping head, thus firmly clamping one end of the transverse grid. At the same time, one end of the grid passes through the pneumatic clamp 222 and extends into the through groove 291, preparing for the subsequent transverse insertion action. At this time, with the help of the coordinated action of the lead screw 218 transmission and the guide rod 221 guidance, it can be ensured that the transverse grid accurately enters the preset position between the upper and lower vertical grids along the through groove 291.

[0025] Additionally, on the base platform 22, located on the side of the base frame 26, there are two sets of moving parts that clamp and move the two ends of the transverse grid after threading to the subsequent processing position. Each moving part includes a concave frame 211 fixedly installed on the base platform 22. The concave frame 211 opens upward, and two sets of parallel guide rods 212 are fixed on the concave frame 211. The guide rods 212 are arranged along the transverse grid conveying direction and are parallel to the lead screw 218 of the threading part to ensure accurate conveying trajectory. The two sets of guide rods 212 are slidably equipped with sliders 213, which can slide smoothly along the guide rods 212. A pneumatic clamp 216 is fixed on the slider 213, with the clamping jaws of the pneumatic clamp 216 facing the wire threading part, for clamping the end of the transverse grid. At the same time, a cylinder 214 is fixed at one end of the concave frame 211. The cylinder body of the cylinder 214 is fixed to the end of the concave frame 211, and its telescopic end passes through the end plate of one end of the concave frame 211 and is rigidly connected to the side of the slider 213, providing power for the movement of the slider.

[0026] After the threading section inserts the horizontal grid between the upper and lower vertical grids, one end of the horizontal grid will extend into the working range of the pneumatic clamp 216. At this time, the pneumatic clamp 216 first opens its clamping jaws, and then quickly closes to clamp the horizontal grid after the end of the horizontal grid is in place. Subsequently, the cylinder 214 is activated, and its telescopic end pushes the slider 213 to move away from the threading section along the guide rod 212, which drives the pneumatic clamp 216 and the clamped horizontal grid to move synchronously, smoothly transferring the woven grid to the subsequent processing position. The entire process is constrained by the guide rod 212 to ensure the transfer accuracy and prevent the grid from shifting or deforming during movement.

[0027] To heat-weld the horizontal grilles interspersed with the vertical grilles, such as Figures 4-5 As shown, a heat-sealing mechanism 3 is provided on the base platform 22. The heat-sealing mechanism 3 includes multiple sets of heat-sealing parts arranged on the base platform 22. The heat-sealing parts correspond to the direction of the woven grid and are distributed in an array. The number of heat-sealing parts is the same as the number of take-up wheels 14 to accommodate the simultaneous processing of multiple sets of grids. The heat-sealing part includes a heat-sealing seat 31 fixedly installed on the side of the base platform 22. The heat-sealing seat 31 provides a supporting base for the horizontal grid. The heat-sealing seat 31 is provided with a pad 311. The pad 311 is made of high temperature resistant material and has a smooth surface, which is suitable for placing the horizontal grid. Multiple sets of vertical grids pass over the upper surface of the heat-sealing seat 31 to maintain the interlacing state with the horizontal grid. Meanwhile, a second movable part 32 is installed on the side of the equipment rack 21. This second movable part 32 has a similar structure to the first movable part, and moves from... Figure 4It can be seen that it moves by guiding and driving components. The slider of the moving part 32 is defined as slider 321. A vertically arranged heating head 322 is fixed on slider 321. The heating head 322 is a heating element that can quickly heat up to achieve heat bonding. The heating head 322 moves up and down with slider 321. When it is close to the heat bonding seat 31, it heats and reinforces the intersection of the horizontal grid and the vertical grid. When it is away, it prepares for the next heat bonding. In addition, a frame 33 is fixedly installed on the equipment rack 21. The frame 33 integrates a PLC control system 331, which controls the operation of various equipment components (such as moving part one, moving part two 32, heat-sealing part, etc.) through preset programs, regulates the weaving and heat-sealing process, and ensures the automation and standardization of grid production.

[0028] It should be noted that after the pneumatic clamp 222 of the threading section inserts the horizontal grille between the upper and lower vertical grilles, both ends of the horizontal grille will simultaneously extend into the working range of the pneumatic clamp 216 of the two sets of moving parts (as can be seen from the layout in the figure, the two sets of moving parts are symmetrically distributed on both sides of the base 22, forming a continuous processing line with the threading section and the heat-sealing section). At this time, the two sets of pneumatic clamps 216 simultaneously open their jaws, waiting to receive the ends of the horizontal grille.

[0029] When it is necessary to transfer and heat-weld the transverse grid, the two sets of pneumatic clamps 216 close synchronously through pneumatic control, firmly clamping both ends of the transverse grid. Subsequently, the cylinder 214 is activated by air, and its telescopic end pushes the slider 213 to move along the guide rod 212 towards the heat-welding part, driving the pneumatic clamps 216 and the clamped transverse grid to move synchronously, smoothly transferring the woven grid onto the pad 311 of the heat-welding seat 31; At this point, the intersection of the horizontal and vertical grids is precisely within the working area of ​​the heating head 322. The second moving part 32 drives the heating head 322 to move downward, using high temperature to heat-bond and reinforce the intersection, completing a coordinated action of weaving-transferring-heat-bonding. Through the symmetrical design of the two sets of moving parts, the straightness and stability of the horizontal grid during the transfer and heat-bonding process are ensured. Combined with the PLC control system 331, automated and standardized production of grid weaving is realized, significantly improving production efficiency and product quality.

[0030] To provide tension to the horizontally and vertically woven grid after heat bonding, in order to facilitate subsequent winding operations, such as... Figure 8 and Figure 10As shown, a pressing mechanism 4 is provided on the equipment frame 21. The pressing mechanism 4 includes an extension frame 41 mounted on the equipment frame 21 via bearings. An auxiliary roller 42 is fixedly installed between the inner walls of the extension frame 41. A rotating shaft 44 is mounted between the inner walls of the extension frame 41 via bearings. Adjusting rods 45 are fixedly sleeved near both ends of the rotating shaft 44. A pressing roller 47 is fixed between the two sets of adjusting rods 45. The pressing roller 47 provides tension for the grid. A second cylinder 46 is fixed on both sides of the inner wall of the equipment frame 21. The telescopic end of the second cylinder 46 is movably connected to the adjusting rod 45. The second cylinder 46 can drive the adjusting rod 45 to rotate, thereby adjusting the position of the pressing roller 47. It should be noted that the vertical height of the pressure roller 47 from the ground is less than that of the auxiliary roller 42 from the ground, so that the horizontal and vertical grids after heat sealing first pass over the bottom surface of the pressure roller 47 and then around to the top surface of the auxiliary roller 42. The height difference between the two and the downward pressure of the pressure roller 47 provide stable tension for the grids, ensuring the smooth progress of subsequent winding operations. At this point, the horizontal and vertical grids first pass over the bottom surface of the pressure roller 47 and then around to the top surface of the auxiliary roller 42. The upward slope formed by the horizontal and vertical grids at this time is defined as the first slope. To address the issue of loose and messy winding caused by the loss of tension after the final section of the grid disappears after passing the pressure roller 47 during winding in a grid weaving machine, the following measures are taken: Figures 8-10 As shown, a tensioning mechanism 5 is provided on the extension frame 41. The tensioning mechanism 5 includes two sets of oppositely arranged guide parts installed on the extension frame 41. The guide parts are composed of guide inclined frames 51 installed on the extension frame 41. The upper surface of the guide inclined frame 51 is provided with a second slope. This slope is composed of an upward slope at one end and a horizontal slope at the other end. The second slope is higher than the first slope in the previous stage. The slope change is used to assist in the control of the grid tension. A groove 52 is provided on the second slope of the guide frame 51. A pulley 53 is slidably connected in the groove 52. The pulley 53 is equipped with a limiting shaft 54. At the same time, limiting grooves 55 are provided on both sides of the groove 52. The limiting shaft 54 ​​is adapted to slide in the limiting groove 55. The limiting groove 55 limits the limiting shaft 54, ensuring that the pulley 53 slides stably only along the groove 52, preventing the pulley 53 from leaving the groove 52, and ensuring the stability of the tensioning mechanism 5. In this way, the sliding of the pulley 53 in the groove 52 is limited, allowing the pulley 53 to move along a preset trajectory.

[0031] The pulley 53 is connected to the clamping part via the support roller 56. The clamping part includes an upper clamping plate 57 and a lower clamping plate 58 connected to one end of the support roller 56 and in a clamping state for the horizontal and vertical grids. The upper clamping plate 57 and the lower clamping plate 58 are connected at one end and a gap is left between them for the horizontal and vertical grids to pass through. The lower clamping plate 58 is provided with a clamping pad 581, which increases the friction between the clamping pad and the grid and improves the clamping stability. A clamping member 571 is movably and through the side of the upper clamping plate 57 near the lower clamping plate 58. The bottom surface of the clamping member 571 is designed with concave and convex features to enhance the biting force with the grid. The upper clamping plate 57 is provided with a through groove that is adapted to the lower clamping plate 58, which is suitable for the lower clamping plate 58 to move up and down along the through groove. An arched frame 59 is fixed on the upper clamping plate 57. The arched frame 59 passes through multiple sets of guide rods 510. One end of the guide rod 510 is connected to the upper surface of the clamping member 571. A spring 511 is sleeved on the guide rod 510. One end of the spring 511 is connected to the arched frame 59, and the other end is connected to the upper surface of the clamping member 571. The spring 511 provides downward pressing force for the clamping member 571. It should be noted that, in the initial state, the horizontal and vertical grids first pass the bottom surface of the pressing roller 47 and then wrap around to the upper surface of the auxiliary roller 42, forming an inclined state. The inclined grids generate an upward lifting force on the clamping member 571, causing the spring 511 to compress. At this time, there is a small gap between the clamping pad 581 of the lower clamping plate 58 and the horizontal and vertical grids. This gap is because the grids push the clamping member 571 upward, so that the clamping member 571 and the lower clamping plate 58 are not completely attached temporarily. However, the elastic force of the spring 511 always maintains a downward trend on the clamping member 571, so that the clamping member 571 continues to contact the grid surface and apply pre-tightening force, ensuring the stability of the grid tension during the normal winding stage.

[0032] Furthermore, when the tension disappears after the last section of the grid passes the pressure roller 47, the horizontal and vertical grids no longer exert an upward lifting force on the clamping member 571. The compression state of spring 511 is released, and the clamping member 571 moves rapidly downward under the elastic restoring force of spring 511 to cooperate with the clamping pad 581 to tightly clamp the horizontal and vertical grids. The elastic force of spring 511 is completely converted into clamping force, filling the gap caused by the disappearance of tension. At the same time, as the subsequent winding operation continues, the clamping part is moved synchronously. Since the clamping part stably clamps the grid, even if the grid itself is not under tension, the friction between the clamping part and the grid can maintain the tension during winding. In addition, because the second slope is higher than the first slope, when the clamping part moves synchronously with the horizontal and vertical grids during the winding operation, it can slide along the second slope and naturally and smoothly pass over the auxiliary roller 42 without mechanical interference with the auxiliary roller 42, ensuring the continuous and stable winding process.

[0033] It should be noted that a contact sensor is installed at one end of the chute 52 (which can be understood as the signal trigger point for winding termination in the figure). When the pulley 53 moves and slides to one end of the chute 52 along with the clamping part, the pulley 53 will touch the contact sensor. The contact sensor immediately sends a control signal to the PLC control system 331. After receiving the signal, the PLC control system 331 controls the winding operation to stop. At this time, one end of the horizontal and vertical grid is firmly pulled by the clamping part, maintaining the tension during winding and avoiding the problem of grid loosening caused by sudden stopping of winding. This ensures that the grid at the end of winding can also maintain a neat and tight state, guaranteeing the product quality during subsequent storage and use.

[0034] To further maintain the clamping force on the horizontal and vertical grilles, such as Figure 9 As shown, a reinforcing part is provided on the side of the upper clamping plate 57. The reinforcing part includes a connecting piece 514 fixed to one side of the upper clamping plate 57. The connecting piece 514 has a concave structure, and spherical protrusions 515 are connected to both ends of the inner wall of the connecting piece 514 by springs (the springs provide elastic extension force to the spherical protrusions 515, allowing them to move within a certain range). The spherical protrusions 515 are partially embedded in the inner wall of the connecting piece 514, and a fastener 513 that engages between the two sets of spherical protrusions 515 is adapted and installed on one side of the lower clamping plate 58. The shape of the fastener 513 is adapted to the concave structure of the mating part 514 and the spherical protrusion 515. In the initial state, there is a small gap between the fastener 513 and the mating part 514. When the upper and lower clamping plates 58 clamp the grid, the fastener 513 is inserted into the mating part 514, and the spherical protrusion 515 pops out under the action of the spring and is locked into the slot of the fastener 513, forming a mechanical lock. This further enhances the connection stability between the upper and lower clamping plates 58 and prevents the upper and lower clamping plates 58 from loosening due to vibration and other factors during the winding process, thereby maintaining the clamping force on the horizontal and vertical grids more reliably. In order to reset the clamping part after use, such as Figures 8-9 As shown, a reset part is provided on the extension frame 41. The reset part includes two sets of reset rods 516 fixed on the extension frame 41. The reset rods 516 provide a guide for the reset action. A sliding pin block 517 is slidably provided on the reset rod 516. A pin groove (not shown in the figure, providing trajectory space for the movement of the sliding pin block 517) is adapted to be opened in the reset rod 516 for the sliding pin block 517 to slide. The sliding pin block 517 has protrusions on both sides. The pin groove is connected to the two sides of the protrusions by side grooves 520 for the protrusions to slide. The side grooves 520 cooperate with the protrusions to restrict the rotation of the sliding pin block 517 and ensure its linear sliding. Meanwhile, a vertically arranged sliding rod 519 is fixed on the pulley 53. One end of the sliding rod 519 movably passes through the sliding pin block 517. The pin groove is connected to a waist groove 521 for the sliding rod 519 to move. The waist groove 521 is adapted to the movement of the sliding rod 519 and provides a certain amount of movement. One end of the sliding rod 519 is provided with an anti-detachment step. The anti-detachment step is used to prevent the sliding rod 519 from detaching from the sliding pin block 517. A buffer spring three is connected between the anti-detachment step and the upper surface of the sliding pin block 517. The buffer spring three is sleeved on the sliding rod 519 to provide elastic buffer for the pulley 53 to reset. A spring two 518 is connected between the sliding pin block 517 and one end of the inner wall of the pin groove. The spring two 518 provides an elastic limiting force for the pulley 53 to the initial position, so that the pulley 53 is kept in the preset initial position when there is no external force. After the clamping part completes the winding auxiliary action, the clamping part and the reinforcing part manually release the clamping constraint on the horizontal and vertical grids. Spring 518, relying on its own elastic restoring force, pulls the sliding pin 517 to slide along the reset rod 516, thereby driving the pulley 53 back to the initial position, realizing the reset of the clamping part, and providing a guarantee for the stable start of the next winding operation. Spring 518 can be set as a damping spring with certain damping characteristics (or a damping pad can be added to the connection end of spring 518 and sliding pin 517). The damping effect consumes the vibration energy when the spring is extended and retracted, and prevents the sliding pin 517 from swaying back and forth along the reset rod 516 under the action of the elastic restoring force of spring 518, ensuring that the pulley 53 can return to the initial position smoothly, and further ensuring the stability of the clamping part after reset. In order to wind up the finished horizontal and vertical grid, such as Figure 2 As shown, a winding mechanism 6 is provided on one side of the equipment frame 21. The winding mechanism 6 includes a winding frame 61 provided on one side of the equipment frame 21. Two sets of vertically arranged side frames 62 are fixed on the winding frame 61. A winding roller 64 is provided between the two sets of side frames 62 through rotating components such as bearings. The winding roller 64 is used to wind and wind the woven horizontal and vertical grid. At the same time, a drive unit 63 is provided on the side of one set of side frames 62. The drive unit 63 can be a power assembly. The power output end of the drive unit 63 is connected to the winding roller 64 for driving the winding roller 64 to rotate, thereby realizing the winding operation of the woven horizontal and vertical grid, making the winding process continuous and stable, and winding the grid orderly on the winding roller 64. Working principle: The unwinding mechanism 1 serves as the starting point for the raw material. The take-up roller 14 overlaps with the overlap frame 13 of the limiting frame 11 via a roller shaft, enabling rapid loading and unloading and stable unwinding. After the grid material is led out through the separator rod 12 and the overlap frame 13, it enters the pressure limiting part of the cross frame 15. The tension is stabilized by the contact pressure of the S-shaped material path and the pressure holding rod 153. Then, it is flexibly guided by the round rod 161 of the guide frame 16 and enters the wire feeding guide mechanism 2. In the wire feeding guide mechanism 2, the perforation 251 of the threading block 25 initially limits the grid. The base frame 26, the second cross bar 29 and other components guide the grid in layers (the lower grid passes through the spacing 210, and the upper grid passes through the upper surface of the second cross bar 29), combing multiple grids into an orderly array, creating conditions for the transverse grid to interweave and ensuring the subsequent weaving accuracy.

[0035] The pneumatic clamp 222 of the threading section clamps the horizontal grid and, with the transmission and guidance of the lead screw 218 and guide rod 221, precisely inserts it into the vertical grid to form an interlaced structure. The pneumatic clamp 216 of the moving section simultaneously clamps both ends of the grid and is driven by the cylinder 214 to move it to the heat-sealing mechanism 3. The moving section 32 drives the heat-sealing head 322 to move down to heat-seale and reinforce the interlacing points. The pressure roller 47 and the auxiliary roller 42 of the pressing mechanism 4 provide initial tension through the height difference. The clamping part of the tensioning mechanism 5 uses the elasticity of the spring 511 and the friction of the clamping part 571 to stabilize the tension. The reinforcement part enhances the clamping force through the mechanical locking of the spherical protrusion 515 and the fastener 513. The reset part uses the damping spring 518 to ensure that the clamping part resets smoothly after the operation is completed, avoiding loosening during winding and ensuring the winding quality.

[0036] After being heat-sealed and tensioned, the grid enters the winding mechanism 6. The drive unit 63 drives the winding roller 64 to rotate and achieve winding. During the winding process, the tensioning mechanism 5 compensates for tension changes in real time. The contact sensor at the end of the chute 52, in conjunction with the PLC control system 331, triggers a stop at the end of the winding, ensuring that the grid is neatly wound. From raw material unwinding to finished product winding, each mechanism, through the cooperation of mechanical structure and control system, forms an automated closed loop of unwinding-weaving-heat-sealing-tensioning-winding, ensuring continuous, stable, and high-quality grid production.
