Description

Technical Field

[0001] The utility model relates to the field of air-conditioning filter processing equipment, in particular to a mesh edge ironing and cutting device. Background Art

[0002] PP mesh, also known as polypropylene mesh, is a mesh fabric made of polypropylene (PP) material. It has multiple properties and a wide range of applications. In the industrial field, polypropylene mesh is widely used in filtration, screening, protection, etc., such as air filter, liquid filter, industrial protection net, etc. The existing technology for trimming PP mesh can be referred to the attached Figure 1 As shown in FIG, the PP mesh is conveyed by a guide shaft assembly 10, and a cutter assembly 23 is rotatably mounted on an adjustment shaft 11. During the conveying process, the cutter assembly 23 trims the PP mesh. However, due to the pulling of the PP mesh edges by the real-time conveying of the mesh, and the difficulty of the cutter to ensure fast mesh severing, the mesh edges of the PP mesh often have loose threads, resulting in low mesh edge utilization. Summary of the Invention

[0003] In order to solve the above problems, the purpose of the present invention is to provide a mesh edge hot cutting device. During the processing, the edges of the PP mesh are softened and pressed, making it easier to cut, thereby alleviating the problem of edge frays and improving product quality.

[0004] In order to achieve the above-mentioned purpose, the present invention adopts the following technical solutions:

[0005] The device for hot-cutting mesh cloth is characterized in that it includes a cloth guide shaft group for conveying the mesh cloth, an adjusting shaft arranged next to the cloth guide path of the cloth guide shaft group, and a cutter assembly for cutting the mesh cloth; a bracket is rotatably provided on the adjusting shaft, and the cutter assembly is rotatably provided on the bracket; it is characterized in that a hot-cutting roller is also rotatably provided on the bracket, and the hot-cutting roller has a first heat source built in; the hot-cutting roller and the cutter assembly can rotate with the bracket relative to the adjusting shaft to make the hot-cutting roller and the cutter assembly close to or away from the cloth guide path; when the hot-cutting roller and the cutter assembly are in contact with the cloth guide path, the hot-cutting roller is located upstream of the cutter assembly.

[0006] The present invention employs the aforementioned technical solution, which relates to a device for hot-cutting mesh fabric. The device comprises a guide shaft assembly comprising multiple guide shafts for guiding the transport of PP mesh fabric. Within the transport path of the PP mesh, brackets on the adjustment shafts rotate relative to the adjustment shafts, thereby controlling the hot-cutting rollers and cutter assembly to move closer to or further from the guide path. During trimming, the hot-cutting rollers and cutter assembly follow the guide path of the PP mesh fabric. The edges of the PP mesh are first pressed by the hot-cutting rollers and then cut by the cutter assembly.

[0007] In this solution, a hot roller is installed upstream of the cutter assembly. This roller heat-presses and softens the edges of the PP mesh before the cutter assembly begins. Furthermore, during the cutting process, the hot roller presses the upstream edge of the PP mesh. This softens and presses the edges, making them easier to cut, reducing edge frays and improving product quality.

[0008] In a further embodiment, the cutter assembly includes a cutter frame rotatably mounted on a support, a cutter mounted on the cutter frame, and an elastic member that elastically presses against the cutter. This allows the blade to conform to the PP mesh during cutting, facilitating cutting.

[0009] In a specific solution, the elastic component is a spring, and the output end of the spring presses against the cutter.

[0010] Furthermore, the cutter in the cutter assembly is connected to a second heat source, which is an electric heating component. The cutter and the electric heating component are in contact and conduct heat. In this solution, the second heat source heats the cutter, and the heated cutter is more likely to cut the edge of the PP mesh.

[0011] In a further embodiment, the first heat source built into the ironing roller is an electric heating element, and the roller surface of the ironing roller and the electric heating element conduct heat to each other by radiation or contact. The electric heating element can conduct heat to the roller surface by radiation or by contact, ultimately requiring the roller surface of the ironing roller to reach the required temperature.

[0012] The electric heating component described in the above solution may specifically be a heating resistance wire.

[0013] In a specific embodiment, an adjusting ring is rotatably sleeved on the adjusting shaft, and the lower end of the bracket is fixed on the adjusting ring. BRIEF DESCRIPTION OF THE DRAWINGS

[0019] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of the technical features being referred to. Thus, a feature specified as "first" or "second" may explicitly or implicitly include one or more of such features. In the description of this utility model, unless otherwise specified, "plurality" means two or more, unless expressly limited otherwise.

[0020] In this utility model, unless otherwise specified or limited, the terms "install", "connect", "connect", "fix" and the like should be understood in a broad sense, for example, they can be fixedly connected, detachably connected, or integrally connected;

[0021] It can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, or it can be the internal communication between two components. For those skilled in the art, the specific meanings of the above terms in this utility model can be understood according to specific circumstances.

[0022] In the present invention, unless otherwise expressly specified or limited, a first feature being "above" or "below" a second feature may include the first and second features being in direct contact, or may include the first and second features being in contact not directly but through another feature between them. Moreover, a first feature being "above," "above," and "above" a second feature may include the first feature being directly above or obliquely above the second feature, or may simply mean that the first feature is higher in level than the second feature. A first feature being "below," "below," and "below" a second feature may include the first feature being directly below or obliquely below the second feature, or may simply mean that the first feature is lower in level than the second feature.

[0023] like Figure 2 and 3 As shown, this embodiment relates to a mesh ironing and cutting device, comprising a fabric guide shaft assembly 10 for conveying the mesh, an adjustment shaft 11 disposed adjacent to the fabric guide path of the fabric guide shaft assembly 10, and a cutter assembly 23 for cutting the mesh. A bracket 21 is rotatably mounted on the adjustment shaft 11. In a specific embodiment, an adjustment ring 12 is rotatably mounted on the adjustment shaft 11, with the lower end of the bracket 21 fixed to the adjustment ring 12. The cutter assembly 23 is rotatably mounted on the bracket 21. A heat roller 22 is also rotatably mounted on the bracket 21. The heat roller 22 incorporates a first heat source, which is an electric heating element. The roller surface of the heat roller 22 conducts heat to the electric heating element via radiation or contact. The electric heating element can conduct heat to the roller surface via radiation or contact, ultimately requiring the roller surface of the heat roller 22 to reach a desired temperature.

[0024] In a further solution, the electric heating component described in the above solution may specifically be a heating resistance wire.

[0025] The ironing roller 22 and the cutter assembly 23 can rotate with the bracket 21 relative to the adjustment shaft 11 to move the ironing roller 22 and the cutter assembly 23 closer to or further away from the cloth guide path. When the ironing roller 22 and the cutter assembly 23 are in contact with the cloth guide path, the ironing roller 22 is located upstream of the cutter assembly 23.

[0026] The fabric guide shaft assembly 10 in this mesh ironing and cutting device includes multiple fabric guide shafts 100, which guide the PP mesh. Within the PP mesh's conveying path, a bracket 21 on an adjustment shaft 11 rotates relative to the adjustment shaft 11, thereby controlling the movement of the ironing roller 22 and cutter assembly 23 toward or away from the fabric guide path. During trimming, the ironing roller 22 and cutter assembly 23 follow the PP mesh's fabric guide path. The edge of the PP mesh is first ironed and pressed by the ironing roller 22, and then cut by the cutter assembly 23.

[0027] In the above solution, the ironing roller 22 is positioned upstream of the cutter assembly 23. Before the cutter assembly 23 begins cutting, the ironing roller 22 heat-presses and softens the edges of the PP mesh. Furthermore, during the cutting process, the ironing roller 22 presses the upstream edge of the PP mesh. This softens and presses the edges of the PP mesh, making it easier to cut, thereby reducing edge frays and improving product quality.

[0028] like Figure 2As shown, the cutter assembly 23 includes a cutter frame 231 rotatably mounted on a bracket 21, a cutter 232 mounted on the cutter frame 231, and an elastic component 233. The elastic component 233 elastically presses against the cutter 232. This elasticity allows the blade to conform to the PP mesh during the cutting process, facilitating cutting. In a specific embodiment, the elastic component 233 is a spring, the output end of which presses against the cutter 232. Furthermore, a second heat source is connected to the cutter 232 in the cutter assembly 23. This second heat source is an electric heating component, and the cutter 232 and the electric heating component are in contact and conduct heat. In this embodiment, the second heat source heats the cutter 232, making it easier for the heated cutter 232 to cut the edge of the PP mesh.

[0029] In summary, when the mesh ironing and cutting device described in the above embodiment operates, the fabric guide assembly 10 conveys the PP mesh, while the ironing roller 22 and cutter assembly 23 follow the fabric guide path of the PP mesh. The edge of the PP mesh is first pressed by the ironing roller 22 to soften the edge. The heated cutter then cuts the mesh. During the cutting process, the ironing roller 22 presses the upstream edge of the PP mesh, allowing the cutter to cut more smoothly and preventing the occurrence of frayed edges.
