Background Technology
[0002] Gypsum board is a material made primarily of building gypsum. Paper-faced gypsum board, on the other hand, is a lightweight board made with gypsum slurry as the core and paper as the facing on both sides. It is characterized by its light weight, sound insulation, heat insulation, strong processing performance, and simple construction methods. During the production process of gypsum board, in order to obtain the required dimensions to form products of different specifications and models, cutting devices such as cutters are used to cut the gypsum board, which has been rolled by a roll forming machine, to the predetermined dimensions. At this time, the gypsum core in the gypsum board is broken, forming gypsum dust and gypsum particles. These dust and particles fall onto the surface of the gypsum board and the ground, causing environmental pollution and harming the health of operators. Furthermore, the dust and particles remaining on the surface of the gypsum board may cause scratches and other defects affecting the appearance quality of the product during subsequent production processes. Utility Model Content
[0003] The purpose of this disclosure is to provide a dust collection device for gypsum board production, which can effectively collect gypsum dust and gypsum particles, thereby reducing environmental pollution and ensuring the appearance quality of gypsum board products.

[0021] The implementation and use of the embodiments are discussed in detail below. However, it should be understood that the specific embodiments discussed are merely illustrative of particular ways of implementing and using this disclosure, and are not intended to limit the scope of this disclosure. The descriptions of the structural positions of various components, such as up, down, top, bottom, etc., are not absolute but relative.

[0024] In this document, unless otherwise explicitly specified, terms such as "attachment" and "connection" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal connection of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this document according to the specific circumstances.
[0025] It is recognized that during the production of gypsum board, the gypsum board, after being rolled by a roll forming machine, is cut into predetermined sizes to form products of different specifications and models. The gypsum dust and particles generated during cutting not only cause environmental pollution but may also affect the appearance quality of the gypsum board products. Typically, receiving troughs are installed on the ground at the cutting location. These troughs can collect and hold the falling gypsum particles to some extent, but their effect on controlling airborne dust is minimal, and there are still health risks for operators when cleaning the receiving troughs.
[0026] Based on the concept of this disclosure, a dust collection device is proposed that can be applied to a gypsum board production system to effectively collect gypsum dust and gypsum particles at the cutting location, reducing dust dispersion without adversely affecting the gypsum board production line. Furthermore, this disclosure also proposes a gypsum board production system incorporating the aforementioned dust collection device.
[0027] Specifically, in combination Figure 1 and Figure 2 The illustrated gypsum board production system mainly includes a conveying device 10 and a cutting device 20. The conveying device 10 includes multiple conveying rollers 11 for conveying roll-formed gypsum boards 30 and cut gypsum boards 30 along the conveying direction D. When the gypsum board 30 is conveyed to the cutting device 20, the cutting device 20, for example, includes a cutter and cuts the entire gypsum board to a predetermined size during conveying. The cut gypsum board is then conveyed by the conveying rollers 11 to a drying device. It should be understood that the gypsum board production system does not only include the devices shown in the figures, and the construction of the conveying device 10 and the cutting device 20 shown is merely an example. Figure 1 For clarity, the conveying device upstream of the cutting device 20 is omitted, and the plasterboard 30 is schematically shown as having been cut.
[0028] Figure 1 As can be seen, according to one embodiment of the present disclosure, the dust collection device 40 is arranged downstream of and adjacent to the cutting device 20. In this way, the dust collection device 40 can reduce the diffusion of dust and particles from the cutting point of the gypsum board, protect the health of the operators, and ensure the appearance quality of the gypsum board product.
[0029] Combination Figures 3 to 5 An exemplary embodiment of a dust collection device 40 is shown. The dust collection device 40 includes an upper dust collection hood 41 and a lower dust collection hood 42, which are arranged opposite to each other to form a dust collection space S. A channel P for gypsum board to pass through is provided between the upper dust collection hood 41 and the lower dust collection hood 42. It should be understood that the size of the channel P should be as close as possible to the thickness of the gypsum board, and suitable for the passage of end caps and tail caps with a larger thickness than the gypsum board during production system startup, thereby not affecting the normal conveying of the gypsum board and effectively preventing dust from flying outside the dust collection device. Applications: Figure 1 and Figure 2 In the gypsum board production system shown, the upper dust collection hood 41 of the dust collection device 40 is arranged above the conveyor rollers 11 of the conveying device 10, and the lower dust collection hood 42 is arranged below the conveying device 10, as shown. Figure 2 shown.
[0030] Advantageously, the dust collection device 40 substantially covers the entire width of the conveyor 10; more specifically, the passage P between the upper dust collection hood 41 and the lower dust collection hood 42 at least substantially covers the entire width of the conveyor 10. Furthermore, advantageously, the dust collection device 40 has a dimension of 300 mm to 700 mm along the conveying direction D of the gypsum board 30, that is, a dimension in the length direction of the conveyor 10, preferably 500 mm. Thus, the dust collection device 40 does not adversely affect the normal conveying of gypsum board on the production line and can effectively collect and remove dust and particles generated during cutting within a reasonable conveying range.
[0031] To effectively collect gypsum dust and gypsum particles, the dust collection device 40 also includes a fan, combined with... Figure 3 As shown, the fan 43 is arranged on the upper dust collection hood 41 to apply air pressure to the surface of the gypsum board passing through the channel P, that is, to apply air pressure on a plane perpendicular to the airflow direction. In this way, the dust and particles generated from cutting the gypsum board can be blown off by the fan and collected in the lower dust collection hood 43.
[0032] In some embodiments, the dust collection device 40 further includes a dust collector 44, which is attached to the lower dust collection hood 42 via a pipe 45 and applies suction to draw out dust and particles from the lower dust collection hood 42 and transfer them to the dust collector 44. Figure 2 As shown. Depending on the needs, the dust collector 44 can be arranged away from the conveying device and attached to the lower dust collection hood 42 by the pipe 45. This is beneficial for the layout of the various devices on the production line and can avoid secondary pollution to the environment and gypsum board at the cutting position when cleaning the dust and particles in the dust collector 44.
[0033] The duct 45 may be provided with an interface 451 for attachment to the lower dust collection hood 42. In some embodiments, the fan 43 and the duct 45 may be arranged on opposite sides of the dust collection device 40, such as... Figure 3 As an example, when the fan 43 applies air pressure, dust and particles are collected in the lower dust collection hood 42 and accumulate on one side relative to the fan 43, thus making it easy to be conveyed to the dust collector 44 via the duct 45.
[0034] In some embodiments, the lower dust collection hood 42 may be configured to gradually increase in size from the side where the fan 43 is arranged toward the side where the duct 45 is arranged, such as... Figures 3 to 5 As shown. With this structure, larger plaster particles will move towards pipe 45 and accumulate at the inlet end 452 of interface 451, such as... Figure 5 As shown, it is thus easier to be sucked away by the dust collector 44.
[0035] Advantageously, the channel P has an inlet 46 and an outlet 47 arranged along the conveying direction of the gypsum board, the inlet 46 and / or the outlet 47 being provided with cleaning components to clean the surface of the gypsum board passing through the channel P, wherein the cleaning components are attached to an upper dust collection hood 41. In some embodiments, the cleaning components may be as follows: Figure 4 The diagram shows a flexible curtain 461 attached at the entrance 46 to the upper dust collection hood 41, and as shown in the diagram. Figure 3 The brush 471 is attached to the upper dust collection hood 41 at the outlet 47. Based on different specifications or thicknesses of gypsum board, the flexible baffle 461 and / or brush 471 can be designed with different dimensions and / or tilt angles. The flexible baffle 461 and / or brush 471 contact the passing gypsum board, so that the dust collection device 40 forms a substantially enclosed dust collection space. This not only cleans dust and particles from the surface of the gypsum board but also prevents dust and particles from drifting outside the dust collection device, while not obstructing the normal passage of gypsum board, end caps, and tail caps. Furthermore, when the dust collector 44 is started, the substantially enclosed dust collection device 40 also helps to create a negative pressure environment, facilitating the dust collector 44 to use greater suction force to suck away dust and particles through the pipe 45.
[0036] The dust collection device 40 may be equipped with connecting parts suitable for attachment to a conveying device. For example... Figure 3 As exemplified, the connecting components may include, for example, pressure plates 48 and corner support members 49 arranged on both sides of the dust collection device 40 (one side is shown as an example in the figure), thereby enabling... Figure 1 The device is shown mounted on the conveyor via fasteners. It should be understood that any other suitable connecting component capable of attaching the dust collection device to the conveyor may be used, and no limitation is made herein.
[0037] After the production system starts, combined with Figure 1 and Figure 2 As shown, the roll-formed gypsum board 30 is conveyed to the cutting device 20 via the conveying roller 11 of the conveying device 10, where it is cut. Simultaneously, the fan of the dust collection device 40, located downstream of the cutting device 20, generates air pressure, blowing off the dust and particles generated during cutting from the surface of the gypsum board 30 and causing them to fall into the lower dust collection hood 42. After further cleaning by the cleaning components at the outlet of the dust collection device 40, the gypsum board 30 passing through the dust collection device 40 has a good surface quality. Furthermore, the dust and particles in the lower dust collection hood 42 can be drawn into the dust collector 44 via the pipe 45 under the negative pressure generated by the dust collector 44, preventing the accumulation of dust and particles in the dust collection device 40.
[0038] The dust collection device disclosed herein can avoid environmental pollution caused by gypsum board cutting during gypsum board production, and can remove gypsum dust and particles from the surface of gypsum board, improving the appearance quality of gypsum board products. Furthermore, the dust collector's design effectively reduces the labor intensity of operators and prevents secondary pollution.
[0039] It should be understood here that the embodiments shown in the figures only illustrate various alternative shapes, sizes and arrangements of the dust collection device according to the present disclosure; however, they are merely illustrative and not limiting. Other shapes, sizes and arrangements may be adopted without departing from the spirit and scope of the present disclosure.
[0040] The technical content and features of this disclosure have been disclosed above. However, it is understood that those skilled in the art can make various changes and improvements to the above-disclosed concept under the inventive concept of this disclosure, but all such changes and improvements fall within the protection scope of this disclosure. The description of the above embodiments is illustrative rather than restrictive, and the protection scope of this disclosure is determined by the claims.
