Description

Technical Field

[0001] The utility model relates to the technical field of scoring of paper-faced gypsum boards, in particular to scoring equipment for producing paper-faced gypsum boards. Background Art

[0002] Gypsum board is made from building gypsum as the primary raw material, with appropriate additives and fibers added to form the core, and a specially prepared paperboard as the facing. Gypsum board offers advantages such as light weight, sound and heat insulation, excellent workability, and simple installation. Gypsum board is available in four categories: standard, water-resistant, fire-resistant, and moisture-resistant.

[0003] Currently, automatic scoring of both sides of gypsum board is typically achieved by combining a conveying device with a scoring device. However, existing devices cannot accurately position the gypsum board. During the conveying process, the angle and position of the gypsum board are easily offset, resulting in tilted or asymmetrical scoring on both sides of the gypsum board, affecting the quality of the gypsum board. In view of this, we propose a scoring device for gypsum board production. Utility Model Content

DETAILED DESCRIPTION

[0028] The following will be combined with the accompanying drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0029] See also Figures 1-6 , a technical solution provided by the utility model:

[0030] A scoring device for producing gypsum board comprises two bases 1, between which a plurality of conveying rollers 2 are rotatably mounted. The plurality of conveying rollers 2 are equidistantly distributed along the length direction of the bases 1 for conveying the gypsum board.

[0031] In this embodiment, a guide device 3 is provided on the base 1 for guiding and positioning the gypsum board.

[0032] Specifically, the guide device 3 includes two extension plates 31, which are respectively fixedly connected to the tops of the two bases 1. The ends of the two extension plates 31 away from the conveyor roller 2 extend to the outside of the base 1. The ends of the two extension plates 31 away from the conveyor roller 2 are each provided with a sliding frame 32, which can slide on the surface of the extension plate 31. The sliding frame 32 includes two horizontal parts and a vertical part. The inner walls of the two horizontal parts are respectively fitted with the upper and lower surfaces of the extension plates 31, which can achieve the purpose of limiting and prevent the sliding frame 32 from moving up and down unintentionally. The tops of the two sliding frames 32 are fixedly connected with folding plates 33, and the two folding plates 33 are provided with scoring devices 4. The two scoring devices 4 are respectively used to score the edges of the two sides of the paper-faced gypsum board.

[0033] See also Figure 3 and Figure 4 The folding plate 33 comprises a vertical section 331 and an inclined section 332 connected to each other. The inclined section 332 extends outward and is used to guide the gypsum board between the two vertical sections 331. The two vertical sections 331 are parallel to each other and are used to limit the sides of the gypsum board to prevent it from shifting or tilting. Multiple guide wheels 34 are rotatably mounted within the folding plate 33. These guide wheels 34 are evenly spaced along the length of the folding plate 33. The guide wheels 34 contact the gypsum board to prevent friction between the sides of the gypsum board and the folding plate 33.

[0034] By adjusting the distance between the two folding plates 33 , the distance between the two sets of guide wheels 34 and the distance between the two scoring devices 4 can be adjusted simultaneously to adapt to gypsum boards of different specifications.

[0035] See also Figure 4 and Figure 5 A limit screw 35 is threadedly connected to the inner wall of the sliding frame 32, and one end of the limit screw 35 abuts against the surface of the extension plate 31 to limit the relative movement between the sliding frame 32 and the extension plate 31, thereby improving the stability of the folding plate 33.

[0036] In this embodiment, the guide device 3 also includes two rotating plates 37. These two rotating plates 37 are arranged in a cross-shaped configuration and are rotatably connected at their centers by a rotating shaft 39, which is used to control the synchronous movement of the two folding plates 33. To coordinate with this, the tops of the two folding plates 33 are fixedly connected to a limit frame 36, which has a sliding groove 361 defined at its top. Sliding rods 38 are fixedly connected to each end of the rotating plates 37, and the two sliding rods 38 are slidably connected to the two sliding grooves 361, respectively, to accommodate the position changes of their ends after the rotating plates 37 rotate. During use, pulling or pushing one of the folding plates 33 causes it to move, via the limit frame 36, driving the sliding rod 38, thereby causing the two rotating plates 37 to rotate.

[0037] See also Figure 6The base 1 is fixedly connected to a fixing frame 5. A socket is provided at the center of the fixing frame 5. The bottom end of the rotating shaft 39 passes through the two rotating plates 37 and is movably inserted into the socket. The socket and the rotating shaft 39 cooperate to limit the position of the rotating plates 37. When the limit frame 36 is pulled, it does not move horizontally via the slide bar 38, thereby allowing the two rotating plates 37 to rotate about the rotating shaft 39.

[0038] Since the rotating shaft 39 is movably connected to the insertion hole and the sliding frame 32 is sleeved on the extension plate 31, the guide device 3 and the scoring device 4 can be removed from the base 1, thereby facilitating the cleaning of gypsum dust in the two devices.

[0039] See also Figure 4 The scoring device 4 includes a connecting frame 41, which is fixedly connected to the top of the folding plate 33. A scoring motor 42 is fixedly connected to the connecting frame 41, and a scoring wheel 43 is fixedly connected to the output end of the scoring motor 42. When in use, the scoring wheel 43 is driven to rotate by the scoring motor 42 to score the paper-faced gypsum board on the conveying roller 2.

[0040] During use, the scoring apparatus for producing gypsum board of the present invention places the gypsum board to be processed on conveyor rollers 2. The conveyor rollers 2 convey the gypsum board, which is then guided by multiple guide wheels 34 on the inclined sections 332 of the folding plate 33, into the vertical sections 331 for horizontal movement. As the gypsum board moves, the scoring motor 42 drives the scoring wheels 43 to rotate, scoring both sides of the board.

[0041] When scoring gypsum boards of different widths is required, the limit screw 35 can be screwed upward to separate the bottom end of the limit screw 35 from the extension plate 31. Subsequently, one of the folding plates 33 is pulled or pushed to one side, which simultaneously drives the limit frame 36 fixed to its top to move. The limit frame 36 drives the slide rod 38 through the slide groove 361, thereby causing the two rotating plates 37 to rotate around the rotating shaft 39. The other end of the rotating plate 37 drives the other limit frame 36 to move through the slide rod 38, ultimately causing the two folding plates 33 to move synchronously in opposite directions, changing the distance between the two rows of guide wheels 34 to accommodate gypsum boards of different specifications.
