[0060] The specific embodiments of the present invention are described in detail below in conjunction with the accompanying drawings. It should be understood that the specific embodiments described herein are only used to illustrate and explain the present invention, and are not used to limit the present invention.

[0061] The following describes the manufacturing method and manufacturing equipment of the non-metallic roller body according to the present invention with reference to the accompanying drawings. The roller body manufactured by the manufacturing method and manufacturing equipment has good structural strength and is easy to produce.

[0062] Traditional roller bodies are mostly made of metal, but the density of metal itself is relatively high, which leads to a large weight of the roller and high energy consumption when the belt conveyor is running. Some existing roller bodies are made of non-metallic materials, but due to the poor mechanical properties of non-metallic materials, a larger wall thickness is required to meet the design requirements, which also leads to a large weight of the roller and high energy consumption when the belt conveyor is running.

[0063] In view of this, see Figures 1 to 10 The manufacturing method of the non-metal roller body of the present application includes:

[0064] The non-metallic extruded cylindrical profile 100 is continuously outputted along the output direction X of the assembly line. The cylindrical profile 100 includes a cylindrical body 101 integrally extruded from a molding extrusion port and a plurality of reinforcing structures connected to the inner peripheral wall of the cylindrical body 101. The plurality of reinforcing structures are arranged along the circumference of the cylindrical body 101 and extend along the axial direction of the cylindrical body 101.

[0065] The cylindrical profile 100 is cut along a direction perpendicular to the output direction X of the assembly line to form a plurality of roller cylinders having a preset length along the output direction X of the assembly line.

[0066] Among them, the non-metallic material extruded cylindrical profile 100 is continuously output along the pipeline output direction X, that is, the non-metallic material cylindrical profile 100 is continuously extruded and formed along the pipeline output direction X. The cylindrical profile 100 includes a cylinder body 101 and a plurality of reinforcing structures connected to the inner circumferential wall of the cylinder body 101, the plurality of reinforcing structures are arranged along the circumference of the cylinder body 101 and extend along the axial direction of the cylinder body 101, and the cylinder body 101 and the plurality of reinforcing structures are extruded from the molding extrusion port as a whole. Since the cylindrical profile 100 is an extruded part, the reinforcing structures of the cylindrical profile 100 extend along the axial direction of the cylinder body 11 and have the same cross-sectional shape. Since the cylindrical profile 100 is a continuously extruded cylinder, it is necessary to cut the cylindrical profile 100 in a direction perpendicular to the pipeline output direction X to form a plurality of roller cylinders with a preset length along the pipeline output direction X, and the preset length of the roller cylinder can be set according to actual production needs.

[0067] The non-metallic roller body prepared by the manufacturing method and manufacturing equipment of the non-metallic roller body of the present application is an extruded part, which can realize the continuous production of the roller body and the flexible manufacturing in the length direction, that is, a set of molding molds can manufacture roller bodies of various lengths, which greatly saves the manufacturing cost of the roller body. In addition, a plurality of reinforcing structures can be integrally formed on the inner circumferential wall of the roller body during the manufacturing process of extrusion molding. The plurality of reinforcing structures are arranged along the circumference of the cylinder body and extend along the axial direction of the roller body. In this way, the structural strength of the non-metallic roller body is effectively enhanced, so that the roller body is not easily deformed when subjected to force, and when the thickness of the roller body made of non-metallic materials such as fiber-reinforced thermoplastic composite materials is relatively thin, it can still meet the structural strength required for normal operation, thereby making the overall structure of the roller body more stable and reliable.

[0068] Further, continuously outputting the extruded cylindrical profile 100 along the output direction X of the assembly line includes:

[0069] Continuously extruding the cylindrical profile 100 along the output direction X of the assembly line;

[0070] The cylindrical profile 100 is cooled and shaped by vacuum negative pressure and continuously output along the output direction X of the assembly line.

[0071] Thus, by cooling and shaping the cylindrical profile 100, deformation of the cylindrical profile 100 after extrusion can be avoided, thereby affecting the shape accuracy and strength of the cylindrical profile 100. In order to ensure the shaping effect of the cylindrical profile 100 during the cooling and shaping process, vacuum negative pressure can be used for cooling and shaping.

[0072] Furthermore, the manufacturing method of the non-metallic roller cylinder of the present application also includes: lathe processing the roller cylinder along the production line output direction X. In this way, the roller cylinder can be processed to a preset outer diameter size by lathe processing the roller cylinder, thereby improving the manufacturing accuracy of the roller cylinder; in addition, lathe processing the roller cylinder along the production line output direction X can make the entire production line manufacturing design of the roller cylinder more reasonable, without the need to add additional transfer procedures and transfer equipment for the roller cylinder, effectively improving production efficiency and reducing production costs. Among them, in the lathe processing step, in addition to lathe processing the outer peripheral wall of the roller cylinder, the structure of the inner peripheral wall of the roller cylinder can also be lathe processed, so that the roller cylinder is more suitable for assembly with the end cover seat of the roller, the assembly accuracy is better, and the assembled roller is more stable and reliable.

[0073] Optionally, after the cylindrical profile 100 is cooled and shaped by vacuum negative pressure and continuously outputted along the output direction X of the assembly line and before the roller cylinder is lathe-processed along the output direction X of the assembly line, the manufacturing method of the non-metallic roller cylinder further includes:

[0074] The cylinder profile 100 is cooled secondary so that when the roller cylinder is lathe-machined along the output direction X of the assembly line, the temperature difference between the roller cylinder and the room temperature is no more than 30°C.

[0075] like Figure 1 As shown, after the cylindrical profile 100 is cooled and shaped and before the cylindrical profile 100 is cut, the manufacturing method of the non-metallic roller cylinder of the present application also includes secondary cooling of the cylindrical profile 100 after cooling and shaping. The secondary cooling of the cylindrical profile 100 after cooling and shaping can ensure that the temperature difference between the roller cylinder 100 and the room temperature is no more than 30°C during lathe processing, effectively ensuring the processing performance and processing accuracy of the non-metallic roller cylinder. In addition, the secondary cooling of the cylindrical profile 100 after cooling and shaping can not only prevent the processing material of the non-metallic roller cylinder from being attached to the lathe tool, thereby ensuring the normal cutting of the roller cylinder, but also prevent the smearing of the material caused by the softening of the non-metallic roller cylinder, thereby reducing the impact on the surface roughness of the roller cylinder and avoiding the phenomenon of processing cracks.

[0076] Optionally, in order to ensure the manufacturing accuracy of the roller body during lathe processing, the minimum tolerance dimension of the outer diameter of the cylindrical profile 100 continuously output along the production line output direction X is greater than the maximum tolerance dimension of the outer diameter of the roller body after lathe processing.

[0077] Optionally, continuously outputting the cylindrical profile along the output direction X of the assembly line further includes: pulling and outputting the cylindrical profile 100 along the output direction X of the assembly line, so that the cylindrical profile 100 can be continuously output along the output direction X of the assembly line.

[0078] Furthermore, the reinforcement structure can be formed in various ways, which will be described below with examples.

[0079] like Figure 4 and Figure 5 As shown, in the cylinder profile 100 of the first embodiment, the reinforcement structure may include strip reinforcement ribs 102, which extend radially inward from the inner circumferential wall of the cylinder body 101 and extend axially. In this way, when the roller cylinder is subjected to force, multiple strip reinforcement ribs 102 can share the force in the axial direction, so that the roller cylinder is not easily deformed when subjected to force, and also when the roller cylinder made of non-metallic materials such as fiber-reinforced thermoplastic composite materials is thin, it can still meet the structural strength required for normal operation, thereby making the overall structure of the roller more stable and reliable. In addition, multiple strip reinforcement ribs 102 are arranged at equal intervals along the circumference of the roller cylinder, which can make the overall structural strength of the roller cylinder better and the force of each part more balanced.

[0080] Optionally, in the cylindrical profile 100 of the second embodiment, as Figure 7 and Figure 8 As shown, the strip reinforcing rib 102 includes a radial connecting end and a radially extending end connected to the inner circumferential wall of the cylinder body 101. The radially extending end of the strip reinforcing rib 102 can extend in the opposite direction along both ends of the circumference to form a reinforcing wing plate 103. In this way, the structural strength of the radially extending end of the strip reinforcing rib 102 can be effectively strengthened, and the radially extending end of the strip reinforcing rib 102 can be prevented from cracking and failing due to stress concentration, thereby further strengthening the overall structural strength of the roller cylinder.

[0081] Optionally, in the cylinder profile 100 of the third embodiment, any two adjacent reinforcing wing plates 103 extend in the circumferential direction and are connected to each other to form a reinforced inner cylinder 104 radially spaced from the cylinder body 101. Fig. 9 and Fig.10 As shown, the cylinder profile 100 includes a cylinder body 101, a plurality of strip-shaped reinforcing ribs 102 and a reinforcing inner cylinder 104. The plurality of strip-shaped reinforcing ribs 102 are arranged at equal intervals along the circumferential direction and radially extend inward from the inner circumferential wall of the cylinder body 101. The reinforcing inner cylinder 104 is radially spaced and concentrically arranged with the cylinder body 101. The reinforcing inner cylinder 104 is connected to the cylinder body 101 through the plurality of strip-shaped reinforcing ribs 102, that is, the plurality of strip-shaped reinforcing ribs 102 are connected between the outer circumferential wall of the reinforcing inner cylinder 104 and the inner circumferential wall of the cylinder body 101. The double-layer cylinder profile 100 has better structural strength and a more stable and reliable overall structure.

[0082] Of course, in addition to the above three embodiments, the cross-sectional shape of the reinforcement structure of the tubular profile 100 may be varied, for example, the cross-sectional shape of the reinforcement structure may be a triangle or other irregular shapes, etc., but the present application is not limited thereto.

[0083] Optionally, the material of the cylinder profile 100 may include a fiber-reinforced thermoplastic composite material or a thermoplastic resin. During the operation of the belt conveyor, when the roller is stuck, the sliding friction between the belt and the roller generates heat quickly. The metal roller cylinder has high strength and much higher temperature resistance than the belt, which can easily cause the high-value belt to eventually burn. Therefore, in some embodiments, the material of the roller cylinder is a fiber-reinforced thermoplastic composite material or a thermoplastic resin. The fiber-reinforced thermoplastic composite material or the thermoplastic resin is not resistant to high temperatures. For example, the maximum operating temperature of the glass fiber reinforced polypropylene composite material does not exceed 110°C. The temperature of the belt conveyor during normal operation is about 60°C. When the roller is stuck, the sliding friction between the belt and the roller generates heat quickly. The roller cylinder of the fiber-reinforced thermoplastic composite material or the thermoplastic resin can collapse quickly, thereby achieving the purpose of protecting the high-value belt.

[0084] In addition, when using resin materials, although the resin materials themselves have a low density, their mechanical properties are poor, resulting in a very large deadweight when meeting the design requirements. Fiber-reinforced thermoplastic composite materials have the advantages of excellent mechanical properties and low density. When fiber-reinforced thermoplastic composite materials are used to prepare rollers, it can not only effectively reduce the energy consumption of the belt conveyor during operation, but also effectively protect the belt, making the belt conveyor more stable and reliable as a whole. At the same time, compared with thermoplastic resins, fiber-reinforced thermoplastic composite materials have higher strength and modulus, as well as lower Poisson's ratio and expansion coefficient. In addition, the cylindrical profile 100 prepared from fiber-reinforced thermoplastic composite materials with lower Poisson's ratio and expansion coefficient is more stable and can be processed with high precision.

[0085] Optionally, the Young's modulus of the fiber-reinforced thermoplastic composite material of the present application is not less than 3.0 GPa. And / or; the Poisson's ratio of the fiber-reinforced thermoplastic composite material of the present application is not higher than 0.4. And / or; the shrinkage rate of the fiber-reinforced thermoplastic composite material of the present application is less than 1%.

[0086] During the extrusion molding process, since the thermoplastic material in the fiber-reinforced thermoplastic composite material is in a molten state, and the added fiber-reinforced material is in a solid state, the fiber-reinforced material is easily flipped onto the outer wall surface of the barrel profile 100, thereby making the surface of the barrel profile 100 rough, thereby increasing the friction between the barrel profile 100 and the belt during use. To this end, the barrel body 101 may have a surface layer 1012 and a structural layer 1011 that are radially stacked and formed by in-mold thermal composite molding. The material of the structural layer 1011 is a fiber-reinforced thermoplastic composite material, and the material of the surface layer 1012 may be a thermoplastic resin material without added fiber-reinforced material. Figure 6 As shown, the strip reinforcement ribs 102 extend radially inward from the inner peripheral wall of the structural layer 1011 and extend axially, that is, the strip reinforcement ribs 102 are integrally formed with the structural layer 1011 and are made of the same material as the structural layer. The surface layer 1012 and the structural layer 1011 are compatible, and physical or chemical compatibility, such as wettability, reactivity and mutual solubility, can be generated between the two, and the bonding strength between the two is high. Alternatively, the surface layer 1012 and the structural layer 1011 can be fixedly connected by an adhesive layer.

[0087] Optionally, the material of the structural layer may be a fiber-reinforced thermoplastic composite material, the fiber in the fiber-reinforced thermoplastic composite material may be one or more of glass fiber, basalt fiber, and carbon fiber. The thermoplastic resin in the fiber-reinforced thermoplastic composite material may be one or more of polyethylene, polypropylene, polyester, nylon, and polyphenylene sulfide.

[0088] Optionally, the material of the surface layer may be one or more of polyethylene, polypropylene, polyester, nylon, and polyphenylene sulfide. Alternatively, the material of the surface layer may be the same as the thermoplastic resin in the fiber-reinforced thermoplastic composite material in the structural layer.
