Technical Field
[0001] This utility model relates to the field of geogrid preparation, and in particular to a universal warp and weft interlacing weaving tool for multi-specification woven strips. Background Technology
[0002] Geogrids are common materials in civil engineering, used to enhance the stability of soil and rock matrices, distribute loads, and prevent deformation. Existing technologies generally employ two manufacturing processes for geogrids: one involves melting and extruding high-molecular polymer materials into sheets, cooling them, punching them, and then heating them with hot air to a highly elastic state, followed by stretching in the warp and weft directions to form a mesh; the other involves weaving geogrid strips, welding, snapping, or injection molding at the overlapping points of the warp and weft strips to form a gridded geogrid.
[0003] The aforementioned processes all have drawbacks to varying degrees. The punching and stretching process results in significant waste of raw materials, and due to technological limitations, the polymer molecular chains at the grid connection points cannot be fully stretched and oriented, with the current 50 kN / m² being a bottleneck. In contrast, a single grid strip is stretched to fully expand and orient the polymer molecular chains, allowing its tensile strength and elongation to approach their physical limits, thus maximizing the performance of the raw materials. Therefore, the weaving process can easily overcome the 50 kN / m² bottleneck of the punching and stretching process. In the weaving process, the traditional method of adjusting the openings of the warp strips is typically used, followed by pushing and interlacing single weft strips to form a woven grid with alternating warp and weft strips.
[0004] The aforementioned method presents two technical problems. First, during the pushing of the weft strip, the weft strip is frequently obstructed by longitudinal notches in the shuttle channel, which are used to adjust the warp strip's vertical position. This prevents the weft strip from completing the weft feeding process normally, requiring manual intervention. To improve efficiency, the warp and weft grid strips are typically layered, with the warp grid strips placed uniformly above or below the weft grid strips and welded at their intersection. While this layered preparation method avoids the process defect of the weft strip being obstructed during pushing, it still presents challenges. However, the layered setup results in low peel strength and poor stability of the overall geogrid system, greatly reducing the basic functions of geogrid in enhancing the stability of soil and rock matrix, distributing loads, and preventing deformation. To compensate for the low peel strength and poor stability caused by welding in the layered setup, a process of injection molding is usually used to reinforce the intersection of the warp and weft strips. In particular, even with the above process, the manufacturing speed of existing equipment is still at a low level due to unreasonable tooling and fixture configuration and the fact that the weft feeding process can only stably push one weft strip.
[0005] Secondly, the molds have low integration. Typically, two custom molds are configured at each intersection point, one above the other. This approach presents technical problems because each mold unit requires separate customization, production, and assembly, leading to difficulties in assembly and maintenance. Furthermore, the redundant mechanical configuration resulting from the interlocking or opposing closing action between modules significantly increases manufacturing and maintenance costs. In particular, existing molds only correspond to a single specification of grille strip, failing to flexibly adapt to grille strips of various widths.
[0006] There is currently no corresponding solution to the above problems. Utility Model Content
[0007] The purpose of this invention is to overcome the shortcomings of existing technologies and provide a simple, versatile, interwoven warp and weft geogrid strips that allows for high-speed, synchronous pushing of multiple weft strips during geogrid production. This results in high manufacturing efficiency, high modular integration, reasonable mechanical configuration, and convenient assembly and maintenance. Ultimately, this ensures overall system stability and high peel strength in geogrid applications, fulfilling the basic functions of geogrids in enhancing soil-rock matrix stability, distributing loads, and preventing deformation.
[0008] A general-purpose warp and weft interlacing weaving fixture for multi-specification braided strips consists of processing unit A and processing unit B. The connection method is that processing unit A and processing unit B are arranged alternately in the warp and weft directions or interlaced to form a matrix.
[0009] The processing unit A has a downward groove on its top and a first grid groove for the passage of a first woven strip. The two banks of the first grid groove are respectively provided with a bevel.
[0010] The processing unit B has a downward-facing groove and a second grid groove. The top of the bevel on the processing unit A is flush with the upper plane of the processing unit A, and the bottom of the bevel is flush with the bottom of the groove at both ends of the second grid groove on the processing unit B; for the passage of the second woven strip.
[0011] The first woven strip feed end is the inlet bank of the second grid groove of processing unit B, and the opposite end is the outlet bank. On the outlet bank, a first woven strip outlet guide slope is provided, and the bottom of the first woven strip outlet guide slope is flush with the bottom surface of the second grid groove of processing unit B.
[0012] The effect achieved in this way is that, after combining the above methods, based on the accompanying drawings in the specification... Figure 1In terms of direction, the first grid groove serves as a latitudinal channel, and the second grid groove is located below the first grid groove and is staggered based on the processing unit A, serving as a lower longitudinal channel.
[0013] The claiming bevel on processing unit A is connected to the second grid groove in processing unit B above it, forming an upper warp belt channel; that is, the upper warp belt channel starts from the bottom of one claiming bevel and runs upward along its slope, vertically through the first grid groove, and then runs downward along its slope from the top of another claiming bevel and exits from the bottom of the slope.
[0014] Based on the above channel configuration, a grid with interlaced warp and weft directions can be manufactured.
[0015] In particular, when the width of the grid strip is smaller than the first or second grid groove, during the weaving process, the grid strip, using the second grid groove as its path, adheres to the inner wall of the groove on the opposite side of the first weaving strip outlet guide slope. This achieves the following effect: when a grid strip perpendicular to it passes overhead, because the width of the grid strip cannot completely fill the second grid groove, the reserved gap may cause the end of the weaving strip passing laterally through the second grid groove to sink into the second grid groove and be blocked by the outlet bank of the second grid groove, resulting in obstruction of the weaving process. However, with the configuration of the first weaving strip outlet guide slope, the grid strip can be guided by its slope, avoiding obstruction during weaving. This effectively adapts to weaving grid strips of different widths.
[0016] The beneficial effects of this utility model are: it solves the problem of inconvenient grid strip weaving due to unreasonable tooling and fixture configuration in the prior art; and realizes the interlaced weaving of grid strips. In particular, by combining two specifications of weaving modules in an alternating manner, a channel for the interlaced weaving of grid strips is naturally formed between the two modules, thereby improving the weaving efficiency of the grid strips. Furthermore, the equipment has a high degree of integration and is easy to maintain. Attached Figure Description

[0026] The realization of the purpose, functional features and advantages of this utility model will be further explained in conjunction with the embodiments and with reference to the accompanying drawings. Detailed Implementation
[0027] Reference Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 and Figure 7 The present invention provides a general-purpose warp and weft interlaced weaving tool for multi-specification woven strips, which consists of processing unit A1 and processing unit B2. The connection method is that processing unit A1 and processing unit B2 are arranged alternately in the warp and weft directions or interlaced to form a matrix.
[0028] The processing unit A1 has a downward groove on its top and is provided with a first grid groove 11 for the passage of a first woven strip. The two banks of the first grid groove 11 are respectively provided with a bevel 12.
[0029] The processing unit B2 has a downward groove on its top, and is provided with a second grid groove 21. The top of the sloping opening 12 on the processing unit A1 is flush with the upper plane of the processing unit A1, and the bottom of the sloping opening 12 is flush with the bottom of the grooves at both ends of the second grid groove 21 on the processing unit B2; for the passage of the second woven strip.
[0030] The first woven strip feeding end is the inlet bank of the second grid groove 21 of processing unit B2, and the opposite end is the outlet bank. On the outlet bank, a first woven strip outlet guiding slope 22 is provided. The bottom of the first woven strip outlet guiding slope 22 is flush with the bottom surface of the second grid groove 21 of processing unit B2.
[0031] The effect achieved in this way is as shown in the attached diagram of the instruction manual. Figure 4 When combined as described above, the first grid groove 11 serves as a latitudinal channel, and the second grid groove 21 is located below the first grid groove 11 and is staggered based on the processing unit A1, serving as a lower longitudinal channel.
[0032] The claiming bevel 12 on the processing unit A1 is connected to the second grid groove 21 in the processing unit B2 above it, forming an upper warp belt channel; that is, the upper warp belt channel starts from the bottom of the slope of one claiming bevel 12, passes upward along its slope surface, passes vertically through the first grid groove 11, and then passes downward along its slope surface from the top of the slope of another claiming bevel 12, and exits from the bottom of the slope.
[0033] Based on the above channel configuration, a grid with interlaced warp and weft directions can be manufactured.
[0034] In particular, when the width of the grid strip is smaller than the first grid groove 11 or the second grid groove 21, when the grid strip is being woven, the grid strip following the path of the second grid groove 21 adheres to the inner sidewall of the groove opposite to the first woven strip outlet guide slope 22. This achieves the following effect: when a grid strip perpendicular to it passes over it, because the width of the grid strip cannot completely fill the second grid groove 21, the reserved gap may cause the end of the woven strip passing laterally through the second grid groove 21 to sink into the second grid groove 21 and be blocked by the outlet bank of the second grid groove 21, resulting in obstruction of the tape entry. However, with the configuration of the first woven strip outlet guide slope 22, the grid strip can be guided by its slope, thus avoiding obstruction during tape entry. This achieves the effect of adapting to the weaving of grid strips of different widths.
[0035] In Example 1, the top of the first braided strip outlet guide groove 22 is flush with the bottom of the first braided strip inlet end groove of the first grid groove 11 of the adjacent processing unit A1.
[0036] This achieves the effect of smooth threading.
[0037] In Example 2, the bottom of the first grid groove 11 of the processing unit A1 is an upwardly sloping surface, and the bottom of the first woven strip outlet end of the groove smoothly transitions to the outer edge of the inlet of the adjacent processing unit B2.
[0038] The effect achieved in this way is smoothing of the feed.
[0039] In Example 3, the inlet bank of the processing unit B2, corresponding to the position of the first grid groove 11 on the processing unit A1, is provided with a first woven strip inlet guide slope. The bottom of the slope smoothly transitions to the outlet end of the first grid groove 11 on the processing unit A1, and the top of the slope is flush with the upper plane of both banks of the second grid groove 21 of the processing unit B2.
[0040] This makes it easier to claim the item by wearing a tag.
[0041] In Example 4, the second grid groove 21 forms a smooth upward slope from the middle section to both ends, and the bottom of the slope of the claiming slope 12 on the processing unit A1 smoothly transitions with the bottom of the groove at the end of the second grid groove 21 on the processing unit B2.
[0042] This achieves the effect of smooth threading.
[0043] In Example 5, at least one of the tops of the claiming bevels 12 on the processing unit A1 is spaced apart from the first grid groove 11, and a second braided strip outlet claiming bevel 23 is provided in the spaced section. The top of the second braided strip outlet claiming bevel 23 is flush with the upper plane of the processing unit A1, and its bottom is flush with the bottom of the first grid groove 11.
[0044] The effect achieved is that, with the first woven strip outlet guide groove 22, when the width of the woven strip is less than the second grid groove 21, the second woven strip outlet acceptance groove 23 is conducive to guiding the grid strip, and based on its guiding effect, it ensures smooth weaving.
[0045] Example 6 describes a weaving module composed of at least one processing unit A1 and one processing unit B2, continuously arranged in four directions or two directions on the same horizontal plane. The weaving module is further divided into an upper weaving module and a lower weaving module. The positions of processing units A1 and B2 in the upper and lower weaving modules correspond to each other; that is, processing unit A1 in each upper weaving module corresponds to processing unit B2 in each lower weaving module. Conversely, processing unit B2 in each upper weaving module corresponds to processing unit A1 in each lower weaving module. The first grid groove 11 on processing unit A1 and the two banks of the second grid groove 21 on processing unit B2 combine to form a first weaving strip channel. Simultaneously, the second grid groove 21 of processing unit B2 corresponds to the bevel 12 on processing unit A1, forming a second weaving strip channel.
[0046] The effect achieved is as shown in the attached diagram in the instruction manual. Figure 3 , Figure 4 As shown, the upper and lower weaving modules are combined to form an interwoven tooling module.
[0047] In Example 7, the processing unit A1 and processing unit B2 on the same weaving module are connected as a single unit.
[0048] The effect achieved in this way is to reduce production costs.
[0049] Example 8: The weaving module includes a long strip weaving module that is integrally connected with the warp and weft directions alternating in sequence;
[0050] Alternatively, the warp and weft directions can be staggered to form a square woven module matrix in the form of a rectangular template.
[0051] The effect achieved in this way is to facilitate processing.
[0052] In Example 9, the slope of the claiming slope 12 is symmetrically arranged, and its slope gradually rises from the outer edges of both banks of the first grid groove 11 to the edge of the first grid groove 11, and the length of the claiming slope 12 is less than the width of both banks of the first grid groove 11.
[0053] This ensures smooth threading.
