Description

Technical Field

[0001] This invention relates to the field of drying equipment accessories technology, and in particular to an integrally molded wall panel and its preparation process and application. Background Technology

[0002] Mesh belt dryers are commonly used in industrial production for material drying. Their main structure includes a mesh belt, unpowered and driven rollers to support and guide the belt, and wall panels for mounting and securing these components, as well as for material shielding and sealing. Currently, most existing mesh belt dryers use modular wall panels, meaning that functions such as material shielding, belt conveying, sampling, and wind protection require the assembly of multiple independent components.

[0003] However, the components of the split wall panel need to be manufactured and processed separately before being assembled on-site. This not only results in a cumbersome production process and low production efficiency, but also makes it prone to gaps and installation deviations at the joints, affecting the overall sealing of the equipment. In addition, existing wall panels lack a guiding structure for the mesh belt and a material shielding structure. During operation, the edges of the mesh belt are prone to detaching from the guide track, and material residue on the mesh belt can easily fall from the gap between the mesh belt and the wall panel and from the installation point of the non-powered roller. This not only affects the normal operation of the drying equipment, but also increases the difficulty of cleaning and maintenance costs. In view of this, the present invention proposes an integrally molded wall panel to meet the usage requirements of mesh belt drying equipment. Summary of the Invention

[0004] This invention provides an integrally molded wall panel, its preparation process, and its application, to solve the technical problems of cumbersome production processes and low production efficiency of existing mesh belt drying equipment for split wall panels.

[0005] To solve the above-mentioned technical problems, the present invention provides the following technical solution: An integrally molded wall panel is mounted on the side of a drying equipment frame. The wall panel is formed by roll forming in one step. The wall panel is bent to form a boss on the side facing inward of the drying equipment frame. The wall panel above the boss is bent to form a rail groove, so that the boss and the rail groove are distributed along the length of the wall panel. Several mounting holes are opened on the boss along the length of the wall panel. The wall panel above the rail groove is inclined to form a slope on the side facing outward of the drying equipment frame.

[0006] Optionally, the angle between the slope and the horizontal plane is in the range of 70° to 80°, and the length of the slope is in the range of 160 to 185 mm.

[0007] Optionally, the boss, the rail groove, and the slope plate are provided in three sets along the width direction of the wall panel. The top of the wall panel is provided with a flange facing the outside of the drying equipment frame. The flange length is 10mm. The bottom of the wall panel is provided with a protruding edge. The protruding edge is 10mm long along the width direction of the wall panel. The flange and the protruding edge are used to connect to the drying equipment frame.

[0008] Optionally, the wall panel has a length of 6300mm, a width of 855-856mm, and a thickness of 0.9-1.1mm.

[0009] Optionally, the wall panel has adapter openings at both ends corresponding to the bosses and rail grooves for mounting the driven rollers of the drying equipment for guiding the mesh belt. A sampling hole is provided at the top of the wall panel for taking samples from the mesh belt during the drying process.

[0010] Optionally, the sampling hole has a radius of 55mm, the mounting hole is an oblong hole with a length of 61mm, a width of 46mm, and an arc radius of 23mm, and 10 mounting holes are provided along the length of the wall panel.

[0011] Optionally, the bending height of the boss is 60mm, the bending depth of the boss is 36mm, the bending height of the rail groove is 6mm, and the bending depth of the rail groove is 36mm.

[0012] Optionally, the bends of the wall panels are provided with rounded chamfers with a radius of 2mm.

[0013] A process for manufacturing an integrally molded wall panel includes the following steps: Step 1, Raw material preparation: Select metal sheets suitable for the working environment of the mesh belt drying equipment as raw materials. The raw material size is pre-treated according to the finished parameters of the wall panel to ensure that the length of the raw material is not less than 6300mm, the width is not less than 856mm, the thickness is 0.9~1.1mm, and the surface of the raw material is free from defects such as scratches, rust, and dents. Step 2, raw material pretreatment: Place the prepared metal sheet into the pretreatment equipment and perform degreasing, rust removal and phosphating treatment in sequence to remove oil, rust and impurities from the surface of the sheet and form a uniform phosphating film on the surface of the sheet. After the pretreatment is completed, dry the sheet to ensure that the surface of the sheet is dry and free of moisture. Step 3, Hole making: Using CNC drilling equipment, holes are made at the preset positions on the wall panel (1), and the mounting holes (2), adapter holes (3) and sampling holes (4) are made in sequence. Among them, the mounting holes (2) are made into waist-shaped holes, and 10 holes are evenly opened along the length of the boss (5). The length of each mounting hole (2) is 61mm, the width is 46mm, and the radius of the arc is 23mm. The adapter holes (3) are made at the positions of the boss (5) and the rail groove (6) at both ends of the wall panel (1), and the size is adapted to the driven roller. The sampling holes (4) are made at the preset position above the wall panel (1), and the hole radius is 55mm. After the holes are made, the holes are ground to remove burrs. Step 4, Roll forming die adjustment: According to the structural design of the one-piece molded wall panel, adjust the die of the roll forming equipment, adjust the die to the preset parameters to ensure that the die can roll form the boss, track, slope, flange and convex edge in one pass. The bending height of the boss is adjusted to 60mm and the bending depth to 36mm, the bending height of the track is adjusted to 6mm and the bending depth to 36mm, the angle between the slope and the horizontal plane is adjusted to 77°~78° and the length is adjusted to 175~176mm, the flange length is adjusted to 10mm, and the convex edge length is adjusted to 10mm. At the same time, ensure that the three sets of bosses, track and slope are evenly distributed along the width of the board, and adjust the radius of the rounded corner of the die to 2mm. Step 5, One-time roll forming: The pre-treated metal sheet is fed into the calibrated roll forming equipment. Using continuous roll forming, the main structure of the wall panel is formed in one step through the extrusion and bending action of the mold. This includes the main plane of the wall panel, bosses, rails, slopes, flanges and protruding edges. It is ensured that after one-time roll forming, the dimensions and positions of each structure meet the wall panel size requirements, the wall panel has no splicing gaps, the structure is compact, and the inner radius of all bends in the wall panel is 1mm. Step Six, Finished Product Inspection and Packaging: Inspect the completed one-piece molded wall panels. The inspection includes: the length, width, and thickness of the wall panels; the dimensions of the bosses, tracks, bevels, flanges, and protruding edges; the dimensions of the mounting holes, adapter ports, and sampling holes; the absence of structural deformation, cracks, scratches, and the accuracy of the rounded corners; the surface flatness and sealing performance; rust-proof packaging is applied to qualified finished products, while unqualified products are returned to the corresponding process for rework until they meet the requirements.

[0014] The beneficial effects of the above-mentioned technical solution of the present invention are as follows: The wall panels of this application are manufactured using a one-time roll forming process, eliminating the need for subsequent splicing, simplifying the production process, enabling mass production, and reducing production difficulty and costs. At the same time, the wall panels are directly connected to the drying equipment frame through flanges and raised edges, making installation convenient and eliminating the need to splice and adjust multiple separate components, which greatly shortens the installation cycle and improves installation efficiency.

[0015] The wall panel of this application can be used to install a non-powered roller through the mounting holes on the boss. The rail groove allows the side of the mesh belt to be embedded. The non-powered roller and the driven roller cooperate to achieve smooth conveying of the mesh belt. The rail groove can effectively limit the mesh belt and prevent the mesh belt from deviating. The side of the mesh belt covers the non-powered roller. With the shielding effect of the rail groove and the slope plate, it can effectively prevent material residue from falling on the mesh belt, reduce equipment cleaning and maintenance costs, and prevent material waste.

[0016] This one-piece molded wall panel integrates material shielding, conveyor belt sealing, sampling, and wind protection functions, eliminating the need for separate shielding, sampling, and wind protection components. This simplifies the overall structure of the conveyor belt drying equipment, reduces space requirements, and lowers overall manufacturing costs. The sampling holes allow for sampling without stopping the machine, ensuring continuous production and improving efficiency. Furthermore, the panel is formed in a single roll forming process, resulting in high overall structural strength and resistance to deformation and damage. Precise bending radii at all bends prevent stress concentration and cracking, enhancing safety during use. Attached Figure Description

[0019] To make the technical problems, technical solutions and advantages of the present invention clearer, a detailed description will be given below in conjunction with the accompanying drawings and specific embodiments.

[0020] like Figures 1 to 7As shown, an embodiment of the present invention provides an integrally molded wall panel, which is side-mounted on the frame 10 of a drying equipment. It is mainly used in mesh belt drying equipment to achieve multiple functions such as material shielding, sealed conveying of the mesh belt 12, sampling, and wind protection. The integrally molded wall panel includes a wall panel 1, which is manufactured using a one-time roll forming process, eliminating the need for subsequent splicing. This effectively ensures the overall structural strength and sealing performance of the wall panel 1, while simplifying the production process and improving production efficiency. The specific dimensional parameters of the wall panel 1 are: length 6300mm, width 855-856mm, and thickness 0.9-1.1mm. The dimensions of the wall panel 1 are adapted to the installation of the drying equipment frame 10.

[0021] In this embodiment, the wall panel 1 is bent to the side facing the inside of the drying equipment frame 10 to form a boss 5. The bending height of the boss 5 is 60mm and the bending depth is 36mm. The boss 5 is distributed along the length of the wall panel 1 and is used to install the unpowered roller 11. Several mounting holes 2 are opened on the boss 5 along the length of the wall panel 1. The mounting holes 2 are oblong holes with dimensions of 61mm in length, 46mm in width, and 23mm in radius. Ten mounting holes 2 are evenly opened along the length of the wall panel 1. The mounting holes 2 are used to install the unpowered roller 11 in the drying equipment. The unpowered roller 11 rotates on the boss 5 through the mounting holes 2 to support and guide the mesh belt 12.

[0022] Furthermore, the wall panel 1 above the boss 5 is bent to form a rail groove 6. The rail groove 6 is parallel to the boss 5 and is also distributed along the length of the wall panel 1. The bending height of the rail groove 6 is 6mm and the bending depth is 36mm. The rail groove 6 is used for the side of the mesh belt 12 to be embedded. There is only a small gap between the mesh belt 12 and the rail groove 6, which can not only ensure the smooth operation of the mesh belt 12, but also limit the mesh belt 12 to prevent it from deviating during operation, and at the same time prevent material residue on the mesh belt from falling from the side of the mesh belt 12.

[0023] Furthermore, the wall panel 1 above the track groove 6 is inclined towards the outside of the drying equipment frame 10 to form a slope 7. The angle between the slope 7 and the horizontal plane is 77° to 78°, and the length of the slope 7 is 175 to 176 mm. The slope 7 is used to shield the material on the mesh belt 12 to prevent the material from falling off the mesh belt 12 during the drying process due to the operation of the mesh belt 12 and the flow of air. The slope 7 also has a windproof function to reduce heat loss during the drying process and improve drying efficiency.

[0024] To further improve the adaptability and performance of the wall panel 1, three sets of bosses 5, rail grooves 6, and slope plates 7 are evenly arranged along the width of the wall panel 1 to accommodate the installation of the three-layer mesh belt 12. A flange 8 is provided on the top side of the wall panel 1 facing the outside of the drying equipment frame 10, with a flange length of 10mm. A protruding edge 9 is provided at the bottom of the wall panel 1, with a length of 10mm along the width of the wall panel 1. The flange 8 and the protruding edge 9 are used to connect the wall panel 1 to the drying equipment frame 10, achieving a stable assembly between the wall panel 1 and the drying equipment frame 10.

[0025] In a further embodiment, the wall panel 1 has an adapter port 3 at both ends corresponding to the boss 5 and the rail groove 6. The size of the adapter port 3 matches the driven roller used to guide the mesh belt 12 in the drying equipment, and is used for the installation of the driven roller. The driven roller cooperates with the unpowered roller 11 to realize the smooth conveying of the mesh belt 12.

[0026] Furthermore, a sampling hole 4 is provided above the wall panel 1. The sampling hole 4 has a radius of 55mm and is used by workers to take samples from the mesh belt 12 for testing during the drying process without stopping the machine, thus ensuring the continuity of production.

[0027] In this embodiment, all bends of the wall panel 1 are provided with rounded chamfers with a radius of 2mm. This design can avoid stress concentration at the bends of the wall panel 1, prevent cracking and deformation at the bends during long-term use, and at the same time avoid sharp edges from causing scratches to workers, thus improving safety during use.

[0028] In this embodiment, the wall panel 1 is made of metal, which has good strength, wear resistance and high temperature resistance, and is suitable for the working environment of the mesh belt drying equipment. The one-time roll forming process can realize mass production, which greatly reduces production and installation costs. Moreover, the overall structure is compact, occupies little space, and is suitable for mesh belt drying equipment of different specifications.

[0029] This embodiment also provides a process for manufacturing an integrally molded wall panel, including the following steps: Step 1, Raw material preparation: Select metal sheets suitable for the working environment of the mesh belt drying equipment as raw materials. The metal sheets must have good strength, wear resistance and high temperature resistance. The raw material size is pre-treated according to the finished product parameters of wall panel 1 to ensure that the raw material length is not less than 6300mm, the width is not less than 856mm, the thickness is 0.9~1.1mm, and the raw material surface is free of scratches, rust, dents and other defects to avoid affecting the quality of subsequent roll forming. Step 2, Raw material pretreatment: Place the prepared metal sheet into the pretreatment equipment and perform degreasing, rust removal, and phosphating treatment in sequence to remove oil, rust, and impurities from the surface of the sheet and form a uniform phosphating film on the surface of the sheet, which enhances the corrosion resistance of the sheet and the forming stability during the subsequent rolling process; after the pretreatment is completed, dry the sheet to ensure that the surface of the sheet is dry and free of moisture, so as to avoid problems such as slippage and forming deviation during rolling. Step 3, Hole Making: Using CNC drilling equipment, holes are made at preset positions on wall panel 1, sequentially machining mounting holes 2, adapter openings 3, and sampling holes 4. Mounting holes 2 are machined as oblong holes, with 10 evenly spaced along the length of the boss 5. Each mounting hole 2 is 61mm long, 46mm wide, and has a radius of 23mm. Adapter openings 3 are machined at both ends of wall panel 1 corresponding to the boss 5 and the rail groove 6, with dimensions matching the driven roller to ensure smooth installation. Sampling holes 4 are machined at preset positions above wall panel 1, with a radius of 55mm, ensuring convenient sampling by personnel. After drilling, the hole openings are polished to remove burrs. Step 4, Roll forming die adjustment: According to the structural design of the one-piece molded wall panel 1, adjust the die of the roll forming equipment and adjust the die to the preset parameters to ensure that the die can roll form the boss 5, the track 6, the slope 7, the flange 8 and the raised edge 9 in one pass. The bending height of the boss 5 is adjusted to 60mm and the bending depth to 36mm, the bending height of the track 6 is adjusted to 6mm and the bending depth to 36mm, the angle between the slope 7 and the horizontal plane is adjusted to 77°~78° and the length is adjusted to 175~176mm, the length of the flange 8 is adjusted to 10mm, and the length of the raised edge 9 is adjusted to 10mm. At the same time, ensure that the three sets of bosses 5, track 6 and slope 7 are evenly distributed along the width of the board. The radius of the rounded chamfer of the die is adjusted to 2mm, which is consistent with the rounded chamfer requirement of the bending part of the wall panel 1. Step 5, One-time roll forming: The pre-treated metal sheet is fed into the calibrated roll forming equipment. Using continuous roll forming, the main structure of wall panel 1 is formed in one step through the extrusion and bending action of the mold. This includes the main plane of wall panel 1, boss 5, track groove 6, slope plate 7, flange 8 and protruding edge 9. This ensures that after one-time roll forming, the dimensions and positions of each structure meet the size requirements of wall panel 1. The wall panel 1 has no splicing gaps and a compact structure. At the same time, all the bends of wall panel 1 are simultaneously roll formed in one step, and the inner radius of the bend is 1mm. Step Six, Finished Product Inspection and Packaging: Inspect the completed one-piece molded wall panel 1. The inspection includes: the length, width, and thickness of the wall panel 1; the dimensions of the boss 5, track groove 6, slope plate 7, flange 8, and raised edge 9; the dimensions of the mounting hole 2, adapter port 3, and sampling hole 4; ensuring the structure is free from deformation, cracks, scratches, and the accuracy of the rounded corners; and ensuring the surface flatness and sealing performance. Qualified finished products are packaged with rust prevention measures to prevent rust and damage during transportation and storage. Unqualified products are returned to the corresponding process for rework until they meet the requirements. The entire process of manufacturing this one-piece molded wall panel is automated. It is rolled and formed in one step without splicing, resulting in high production efficiency. The parameters of each step are controllable, which can ensure the quality stability of the wall panel 1. Mass production can significantly reduce production and installation costs, while also being compatible with the use of mesh belt drying equipment.

[0030] The working process of the one-piece molded wall panel provided by this invention applied to a mesh belt drying equipment is as follows: The wall panel 1 is mounted upright on both sides of the drying equipment frame 10. It is securely connected to the drying equipment frame 10 through the flange 8 and the raised edge 9, ensuring the installation stability of the wall panel 1 and the overall sealing of the equipment. The non-powered roller 11 is installed through the mounting holes 2 of the boss 5 on the wall panel 1, and the driven roller is installed through the adapter ports 3 at both ends of the wall panel 1. The non-powered roller 11 and the driven roller cooperate with each other to form the support and guiding structure of the mesh belt 12. The side of the mesh belt 12 is embedded in the rail groove 6 of the wall panel 1. The small gap between the rail groove 6 and the mesh belt 12 plays a limiting role for the mesh belt 12, preventing the mesh belt 12 from deviating left or right during operation and ensuring that the mesh belt 12 transports materials smoothly and steadily. Furthermore, the non-powered roller 11 installed on the boss 5 is covered by the side of the mesh belt 12. With the shielding effect of the rail groove 6, it can effectively prevent material residue on the mesh belt 12 from falling from the installation point of the non-powered roller 11 and the side of the mesh belt 12. The inclined plate 7 above the rail groove 6 can shield the material on the mesh belt 12, preventing the material from falling during the drying process due to airflow, mesh belt operation and other factors. At the same time, the inclined plate 7 can prevent the heat inside the drying equipment from escaping outward, playing a role in windproofing and heat preservation, and improving drying efficiency. The wall panel 1 is formed by one-time roll forming without splicing gaps. With the tight connection between the flange 8 and the raised edge 9 and the drying equipment frame 10, the sealing performance of the equipment is further improved, reducing heat loss and material leakage.

[0031] During the material drying process, workers can directly sample from the mesh belt 12 through the sampling hole 4 above the wall panel 1 without stopping the machine. This ensures convenient sampling without affecting the continuity of production, and allows workers to promptly check the dryness of the material and adjust the drying parameters. This integrated wall panel 1 combines the functions of material shielding, mesh belt sealing and guiding, sampling port, and wind deflector. While ensuring stable guiding of the mesh belt 12, it effectively solves problems such as material residue falling and heat loss, ensuring the efficient and stable operation of the mesh belt drying equipment.

[0032] The above description represents the preferred embodiments of the present invention. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principles of the present invention, and these improvements and modifications should also be considered within the scope of protection of the present invention.
