Description

Technical Field

[0001] The invention belongs to the technical field of engineering material manufacturing, and in particular relates to a mesh product threading die, equipment and product. Background Art

[0002] The combination of wire mesh and fabric has significant advantages and wide demand in the construction field and other fields. This product combines the high strength, stability and durability of wire mesh with the flexibility and crack resistance of fabric, making it excellent in enhancing the tensile, compressive and crack resistance of structures. Especially in the construction field, it is widely used in projects such as concrete reinforcement, wall insulation, and waterproof layer reinforcement, which can effectively prevent cracking and structural deformation and increase the service life of buildings. In addition, the product is easy to install and light in weight, which can reduce construction costs and time, meeting the urgent needs of modern buildings for efficient, environmentally friendly and durable materials.

[0003] Take mesh products used in projects such as swimming pools, basements, and tunnels that require a high-strength waterproof barrier. The core characteristics of this material come from the clever combination of wire mesh and sheet fabric. The wire mesh gives the product excellent mechanical strength and stability, enabling it to withstand large tensile forces and stresses, thereby effectively preventing cracking and deformation. The sheet fabric is usually made of non-woven fabric or polyester fabric. Its flexibility and adhesion enable the waterproof membrane to fit closely to various complex substrates during the laying process, ensuring seamless coverage. In addition, the surface of the fabric is usually treated with a polymer coating or waterproof coating, which further enhances the product's waterproof performance and anti-aging ability. This combination of mesh and fabric not only enhances the overall durability of the material, but also provides excellent waterproof and moisture-proof properties, making it an ideal waterproof and shaping solution for high-demand scenarios.

[0004] At present, mesh products composed of metal wire mesh and planar fabric (of any material) face multiple problems and deficiencies in the manufacturing process, as shown below:

[0005] Complex and inefficient processing steps: Combining the planar metal mesh with the planar fabric is a key step in the manufacturing process. However, existing processing methods, including tying and connecting, bonding with a third material, or directly applying and fixing with construction site materials at the construction site, all have complex processes and cumbersome operations. These steps not only increase production time and reduce manufacturing efficiency, but may also lead to increased production costs.

[0006] Poor stability of finished products: Whether it is tied or bonded with a third material, the stability of the finished product is often difficult to guarantee due to the heterogeneity of the materials and the limitations of the connection method. This connection method is prone to problems such as falling off and separation during use, affecting the overall strength and durability of the product, and thus affecting the quality and safety of the project.

[0007] Adhesive material selection and compatibility issues: When using a third material for bonding, compatibility issues between different materials often plague the manufacturing process. The selection of adhesive materials must take into account the physical properties of the metal mesh and the fabric, and also ensure that the bonded materials can remain stable for a long time in various environments. However, due to the large differences in material properties, finding a suitable adhesive and ensuring its long-term effect has become a major challenge.

[0008] Uncontrollable on-site fixing: Although the practice of directly applying mesh products to the construction site and fixing them with on-site materials can simplify some manufacturing steps, it also introduces the risk of uncontrollable construction quality. During the construction process, the selection of fixing methods and materials often varies depending on the operating experience of the construction personnel and changes in on-site conditions, resulting in different fixing effects, thus affecting the quality and safety of the entire project.

[0009] Insufficient product consistency and standardization: Due to the limitations of existing manufacturing methods, it is difficult to achieve high consistency in the quality and specifications of mesh products. This difference makes it difficult to achieve product standardization in large-scale applications, which in turn affects the efficiency of construction and the quality of the final building.

[0010] Environmental and durability issues: Adhesives and other fixing materials may be affected by environmental factors such as high temperature, humidity, chemical corrosion, etc. during long-term use, resulting in performance degradation or even failure. These issues question the durability and reliability of mesh products, and they cannot fully meet the high durability requirements of modern architecture for materials.

[0011] In view of the above problems, the mesh products composed of metal wire mesh and planar fabric still have many deficiencies in the manufacturing process, and are in urgent need of technical improvement and innovation to improve the manufacturing efficiency, stability and standardization level of the products and meet the increasingly stringent quality requirements of construction projects.

[0017] The second purpose of the present invention is to provide a wire threading equipment for mesh products, comprising the mesh product wire threading mold according to any one of claims 1 to 4, characterized in that it comprises a fabric feeding roller, a mesh feeding roller, a die unit, a wire threading mechanism and a winding roller, wherein the fabric feeding roller and the mesh feeding roller are located on one side of the die unit and convey the fabric and the mesh to the die unit, and the winding roller is located on the other side of the die unit for winding up the mesh product; the die unit comprises N sets of the mesh product wire threading molds, the mesh product wire threading molds are arranged in a horizontal straight line in a direction perpendicular to the fabric and mesh feed, and the lower mold is located below the mesh surface body and the cloth surface body, the upper mold is located above the mesh surface body and the cloth surface body, one of the upper mold and the lower mold is fixed in position, and the other of the upper mold and the lower mold is connected to a die cylinder that drives its movement; the wire threading mechanism is located on one side of the end of the die unit, and the wire threading mechanism is provided with a wire threading drive roller for driving the transverse wire strip to insert the linear groove of the die unit and a cutter for cutting the wire strip.

[0023] The special mold for combining the metal mesh with the planar fabric proposed in the present invention innovatively solves many problems existing in the traditional processing methods and exhibits many significant advantages and effects.

[0024] First, the mold, through its unique temporary plastic effect, enables the planar fabric to form spaced ridges during processing. This design not only gives the fabric a better three-dimensional sense and structural support, but also provides a precise channel for the subsequent thread insertion. Through these ridges, the thread can be quickly inserted laterally, so that it acts as a suture between the fabric and the metal mesh. This suture effect does not require the use of additional adhesives or external materials, but relies entirely on the physical interlacing of the thread to achieve a stable combination of the metal mesh and the planar fabric. This combination method greatly improves the stability and reliability of the overall structure, ensuring the durability and tensile strength of the finished product.

[0025] Secondly, the design of the mold is not limited to achieving the combination of fabric and mesh, it also further strengthens the metal mesh during the threading process. Traditional metal meshes often require high-strength mesh materials to maintain structural stability when combined with other materials. This mold performs additional reinforcement on the mesh during the threading process, reducing the strength requirements of the metal mesh material. This feature allows the selection of lower-cost, lower-strength metal mesh materials, thereby reducing production costs without affecting the quality and performance of the finished product.

[0026] In addition, this mold simplifies the processing process and improves production efficiency. Since external bonding materials are no longer required, the process complexity and material preparation time are reduced during the production process, further reducing production costs. Its automated and integrated processing method makes large-scale production possible, significantly improving production efficiency and product consistency.

[0027] Finally, the structure achieved by the mold is not only physically stable and reliable, but also has good adaptability. The combination of surface fabric and metal mesh can be applied to various types of materials and different application scenarios, and has a wide range of application potential. This versatility makes the mold not only suitable for the manufacture of waterproof materials in swimming pool construction, but also can be extended to other fields that require similar combined structures, such as building protection nets, composite material structures, etc.

[0028] In summary, this special mold achieves an efficient and stable combination of metal grid and planar fabric through its unique design. It has many advantages such as low material cost, high production efficiency, strong structural stability, and wide versatility, providing a new solution for production and manufacturing in related fields.

[0037] In order to make the purpose, technical solution and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0038] In order to solve the problems of complex processing, poor stability, insufficient bonding compatibility, high construction uncontrollability and difficulty in standardization in the manufacturing process of mesh products composed of metal wire mesh and planar fabric, the present invention provides a mesh product threading die, equipment and product. In order to further illustrate the structure of the present invention, the detailed description is as follows in conjunction with the accompanying drawings:

[0039] Embodiment 1

[0040] See also Figure 1 , a mesh threading product, including a mesh surface body 1 and a cloth surface body 2, the mesh surface body is a rectangular mesh surface body, the mesh surface body and the cloth surface body are connected by transverse wire strips, and the transverse wire strips 3 span the longitudinal mesh wires of the mesh surface body and penetrate the cloth surface body in the cells of the mesh surface body. The mesh surface body is a planar mesh body composed of rib-like components with certain toughness and strength, which serves as the rigid basis of the mesh threading product. The cloth surface body is a flexible woven surface body, which selects different materials and weaving densities according to the specific application field, or has a waterproof coating or other functional layers, which are not limited here. This product is intended to include a combination product of a mesh surface body as a rib body and a cloth surface body as a functional surface body. For example, a new waterproof product for swimming pools.

[0041] In this embodiment, the mesh surface body is a metal mesh surface body formed by connecting transverse mesh wires and longitudinal mesh wires, and the mesh is a rectangular mesh. The transverse mesh wires and longitudinal mesh wires are straight metal wire strips with certain rigidity and toughness, which are welded or tied to form a planar metal mesh surface body. The mesh surface body and the cloth surface body are superimposed. The transverse wire strips are usually straight metal wires of the same material and thickness as the transverse mesh wires and the longitudinal mesh wires, and are required to have certain toughness and rigidity. The transverse wire strips are located on the outside of the mesh surface body, and the mesh surface body and the cloth surface body are sutured by interlacing the cloth surface body part in the unit grid. The transverse wire strips are interlaced through the face of the cloth surface body in the unit grid, and a bulge needs to be temporarily formed here, and the transverse wire strips pass through in a straight line to achieve the above-mentioned suture connection. That is, the mesh surface body is located between the cloth surface body and the transverse wire strips, and the transverse wire strips are sutured with the cloth surface body by interlacing the cloth surface body, so that the cloth surface body and the mesh surface body are connected into a product. This method of connecting the mesh surface body and the cloth surface body does not require the use of external connecting parts, such as binding parts, and the mesh surface body and the cloth surface body can be processed independently as prefabricated materials, and there is no assembly accuracy requirement between the two. After threading, the part of the cloth surface body serves as a connection, and there is no risk of separation. Most importantly, the special structural design of this mesh threading product, in addition to simplifying the structure and connection method of the product itself, provides a new process method for its production and manufacturing, that is, the mesh surface body and the cloth surface body as prefabricated materials can be connected through rapid horizontal threading, which greatly improves the processing efficiency.

[0042] Embodiment 2

[0043] See also Figure 2-Figure 6 A wire threading die for a mesh product comprises a lower die and an upper die, a ridge-shaped die gap is formed between the upper die 4 and the lower die 5 in a mold-closed state, two ends of the ridge-shaped die gap extend to both sides to the outer side surfaces of the upper die and the lower die, and a linear groove runs through the upper die and the lower die in the mold-closed state, the linear groove runs through the inclined surfaces on both sides of the ridge-shaped die gap, and the axis of the linear groove is parallel to the inner side surface of the plane die gap.

[0044] N groups of upper dies and lower dies are arranged in a transverse straight line. When the upper dies and lower dies are in a state of mold closing, the ridge-shaped mold gap is used to form transversely spaced protrusions on the cloth surface body described in the first embodiment. Through the feed control of the stacked mesh surface body and the cloth surface body, the protrusion is formed in the rectangular grid of the mesh surface body, and the direction of the protrusion is set on one side of the mesh surface body. When the upper dies and lower dies are in a state of maintaining the protrusion, that is, in a mold closing state, the N groups of upper dies and lower dies arranged in a transverse line jointly form a wire threading hole that transversely penetrates the protrusion. The wire threading hole is formed by connecting the upper and lower straight grooves. Under the guiding action of the wire threading hole, the transverse wire strip can quickly pass through all the protrusions. After the transverse wire strip is threaded, the upper dies and lower dies are opened to complete a longitudinal connection of the mesh surface body and the cloth surface body by a transverse wire strip.

[0045] In this embodiment, specifically, the upper part of the lower mold is the lower molding surface, and the lower part of the upper mold is the upper molding surface. This is a known technology in the field of mold design, and the molded material is formed into a desired shape through the mold gap formed between the two molding surfaces in the mold closing state.

[0046] The lower molding surface includes a lower plane portion located on both sides and an upper convex portion 5-2 located between the two lower plane portions 5-1 and forming a ridge-shaped protrusion upward. The upper molding surface includes an upper plane portion 4-1 located on both sides and an upper concave portion 4-2 located between the two upper plane portions and forming a concave shape upward. The shape of the lower convex portion and the upper concave portion fits and a ridge-shaped mold gap is formed between them, and a plane mold gap is formed between the upper plane portion and the lower plane portion. In the mold closing state, the ridge-shaped mold gap is consistent with the plane mold gap, and there is no restriction on the width of the gap. It is just a description of the molding space formed by forming the expected shape. And the shape description of the above-mentioned molding surface, its viewing angle is the direction perpendicular to the arrangement direction of the N groups of molds, that is, the longitudinal view from the grid surface body. The width between the roots of the two sides of the ridge-shaped protrusion is smaller than the lateral width of the rectangular grid of the grid surface body to ensure that the cloth surface body can form a protrusion in the rectangular grid.

[0047] The lower die is provided with a linear groove 6 that passes through the lower convex part, and the upper die is provided with a linear groove that passes through the two sides of the upper concave part. In the mold closing state, the lower convex part of the lower die is embedded in the upper concave part of the upper die. The combination of the upper die and the lower die in the mold closing state forms a rectangular cube as a whole. The linear groove of the lower die and the linear groove of the upper die form a transverse threading hole for threading wire guide, and this threading hole passes through this cube horizontally. The threading hole described here is not limited to a hole structure in its entirety, but a functional description. It is formed by connecting a plurality of linear grooves spaced apart in the upper and lower directions, and the cross-sectional shape formed by the linear grooves at the junction of the upper die and the lower die is a hole. The linear groove is a notch on the forming surface that is formed by the depression of the forming surface and is similar to a linear gap.

[0048] The side end faces of the upper die and the lower die are planes perpendicular to the axis of the linear groove. The two side end faces of the upper die form the ports of the linear groove. The inclined surface of the upper concave part of the upper die and the inclined surface of the upper convex part of the lower die are provided with corresponding ports, and the ports facing the same side form a flared shape. The flared shape is a trumpet-shaped structure, facing the direction of wire threading, to ensure that the front end of the transverse wire strip can smoothly pass through the linear groove. A chamfered structure is formed between the top of the upper convex part and the inclined surface forming the ridge. This design is to avoid the upper convex part from forming a hard pressure crease in the process of making the cloth body convex, and to avoid shear damage to the cloth body.

[0049] Embodiment 3

[0050] See also Figure 7 and Figure 8 A wire threading equipment for mesh products comprises a fabric feeding roller 7, a mesh feeding roller 8, a die unit 9, a wire threading mechanism 10 and a winding roller 11.

[0051] The fabric feed roller is a conveying roller used to convey the fabric body toward the die unit. It is a roller group composed of multiple rollers. The conveying structure and method of this flexible surface fabric belong to the known technology in the existing mechanical field, and ultimately the fabric body is conveyed toward the die unit in a horizontal and longitudinal direction and passes through the die unit.

[0052] The grid feed roller is a conveying roller used to convey the grid surface body toward the die unit. This grid feed roller refers to the main roller used to convey the grid surface body. It is a cylindrical roller as a whole, and its axis is parallel to the axis of the fabric feed roller, and both are horizontally arranged. The roller surface of the grid feed roller is evenly provided with convex teeth. The convex teeth are convex structures formed on the roller surface. This convex structure is evenly distributed on the roller surface. In the process of the grid surface body winding and contacting the roller surface, this convex structure is embedded in the rectangular grid of the grid surface body, so as to realize the driving of the rotating grid feed roller to feed the grid surface body. The grid feed roller is connected to the grid feed motor used to drive its rotation.

[0053] The winding roller is used to roll up the mesh surface product, that is, the combination of the mesh surface body and the cloth surface body, and the winding roller is connected to the winding motor. The winding roller is a roller group composed of multiple rollers. The automatic winding structure and method of this flexible surface cloth belong to the known technology in the existing mechanical field, and finally the combined product of the mesh surface body and the cloth surface body is rolled up. The axis of the winding roller is coaxial with the fabric feed roller and the grid feed roller, and both are horizontal. At the same time, the winding roller is also a component that provides feeding power for the mesh surface body and the cloth surface body. It is an active roller, which uses the winding force to provide synchronously moving feeding driving force for the mesh surface body and the cloth surface body.

[0054] The fabric feed roller and the mesh feed roller are located on one side of the die unit and feed the fabric and mesh to the die unit. The winding roller is located on the other side of the die unit and is used to wind up the mesh surface product. The mesh feed roller ultimately enables the mesh surface body to be transported to the die unit in a horizontal and longitudinal direction and pass through the die unit, and the mesh surface body is stacked and laid on the cloth surface body for synchronous feeding. This feeding method is achieved by designing the mesh feed roller, the fabric feed roller and the winding roller on the other side. Under the joint action of the three rollers, the mesh surface body and the cloth surface body intermittently pass through the die unit in a horizontal and longitudinal manner in which they are stacked horizontally and longitudinally from top to bottom.

[0055] The die pressing unit is a working unit that processes the mesh surface body and the cloth surface body that are fed synchronously, so that the cloth surface body forms a convexity at the rectangular grid of the corresponding mesh surface body. The die pressing unit is transversely arranged on the stacked mesh surface body and the cloth surface body.

[0056] Specifically, the die pressing unit includes N sets of mesh product threading dies, which are arranged in a horizontal straight line in a direction perpendicular to the fabric and mesh feed, and the lower die is located below the mesh surface body and the cloth surface body, and the upper die is located above the mesh surface body and the cloth surface body. Specifically, it can be understood that in the lateral direction of the mesh surface body and the cloth surface body forming a stacked and bonded horizontal surface body, the mesh product threading dies form spaced protrusions in the mold closing state, and this protrusion makes the cloth surface body form an upward protrusion in a row of lateral grids of the mesh surface body. And in the mold closing state, all mesh product threading dies in the die pressing unit form transversely through threading holes, which are guide channels for threading lateral wire strips.

[0057] One of the upper mold and the lower mold is fixed in position, and the other of the upper mold and the lower mold is connected to a die cylinder that drives its movement. In the present embodiment, the lower mold is fixed, and the upper mold is driven by a die cylinder. The upper mold of each mesh product threading mold is driven independently, and the fixed lower mold is not required. The lower molds of N sets of mesh product threading molds can be used as split types, or the lower molds of all sets of mesh product threading molds can be used as an integrated type. As for the specific fixing method of the lower mold, it can be fixed on the main frame of the equipment, which belongs to the conventional technology in the mechanical field. In the present embodiment, the die unit includes a lower beam body and an upper beam body that are arranged across the feeding direction of the fabric and the grid, the lower mold is fixed to the lower beam body, the die cylinder is fixed to the upper beam body, and the upper mold is installed on the cylinder rod that the die cylinder extends downward.

[0058] The wire threading mechanism is used to drive the transverse wire strip to pass through. The wire threading mechanism is located at one end of the die unit. The wire threading mechanism is provided with a wire threading drive roller for driving the transverse wire strip to insert into the linear groove of the die unit and a cutter for cutting the wire strip. The wire threading mechanism is a drive assembly that drives the wire strip to be inserted into the die unit transversely, and is intended to provide a driving force for the axial movement of the transverse wire strip. At present, in the field of machinery, there are a variety of known wire strip axial drive devices and cutter structures for real-time cutting of the wire strip.

[0059] In this embodiment, the wire threading drive roller includes an upper pressure roller 12 and a lower pressure roller 13, and one of the upper pressure roller and the lower pressure roller is connected to the wire threading drive motor. Specifically, the wire threading mechanism has a main frame, and two groups of pressure roller assemblies arranged front and back are installed on the main frame. Each group of pressure roller assemblies consists of an upper pressure roller and a lower pressure roller arranged up and down. In this embodiment, the lower pressure roller is a fixed roller, which is connected to the wire threading drive motor and is an active roller. The upper pressure roller is a clamping roller, and after installation, a preload force is maintained to squeeze the roller surface of the lower pressure roller. The transverse wire strip is clamped between the lower pressure roller and the upper pressure roller, and the wire feeding and wire threading are achieved by rotating the lower pressure roller. In order to ensure the stability of the transverse wire strip, the lower pressure roller or the upper pressure roller can be designed as a groove roller, that is, the outer circumferential surface is provided with a groove for maintaining the position of the transverse wire strip. This design also belongs to the conventional design in the mechanical field. In the upstream of the wire threading mechanism, a wire strip straightening mechanism 14 can be provided as needed to straighten the wound wire strip and then feed the wire.

[0060] The cutter is used to cut the transverse wire strips after the wire threading is completed. In this embodiment, the cutter 15 includes a cutter seat 16, a cutting head and a cutting drive motor for driving the cutting head. The cutter seat and the cutting head are provided with matching cutting edges. The side of the die unit corresponding to the cutter seat is provided with a wire strip lead-out hole aligned with the linear groove. The structural design of the blade of the cutter can be designed as an oblique blade, so that the end of the cut transverse wire strip forms a wedge-shaped section, forming a tip that is convenient for threading the wire.

[0061] In this embodiment, a trimming mechanism is included, which is arranged on both sides of the fabric and the grid and located behind the die unit. The trimming mechanism is provided with a cutter for cutting off the ends of the wire strips. The trimming mechanism is a cutter that moves up and down to cut off the extended parts of the two ends of the transverse wire strips after the wire threading is completed.

[0062] Embodiment 4

[0063] A wire threading process using the wire threading die for mesh products described in the second embodiment comprises the following steps:

[0064] S1.N group of mesh surface products threading dies are arranged horizontally;

[0065] S2. The mesh surface body and the cloth surface body are horizontally stacked between the lower mold and the upper mold;

[0066] S3.N group mesh surface product threading mold from the middle to both sides of the mold in sequence;

[0067] S4. Insert the transverse wire strip from one end into the linear groove of the wire threading mold of all mesh products.

[0068] In the wire threading process of the above-mentioned mesh product wire threading mold, the mesh product wire threading mold is closed in sequence from the middle to the two sides, which can avoid the stress tearing caused by the cloth surface body forming a wavy shape with spaced protrusions at the moment of closing the mold due to the simultaneous closing of all the mesh product wire threading molds. In the process method of the present technical scheme, at the moment of closing the middle mold, the two sides of the cloth surface body are still in a free state, which completely eliminates the tearing stress and avoids material damage.

[0069] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
