DETAILED DESCRIPTION

[0023] The technical solutions in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the utility model.

[0024] The utility model provides a kind of slurry cleaning device, including the H-shaped scraper 2 of being set to the outer side of conveying belt 1 tail end, H-shaped scraper 2 is fixedly installed on rotating holder shaft 4 by scraper holder 3, and the both ends of rotating holder shaft 4 are rotatably connected on equipment support 5;

[0025] Tensioning mechanism is also installed on equipment support 5, and tensioning mechanism can make rotating holder shaft 4 have the tendency of rotating to conveying belt 1, so that the head of H-shaped scraper 2 keeps contact with conveying belt 1.

[0026] The above-mentioned slurry cleaning device, by the tensioning force of tensioning device, make rotating holder shaft 4 have the tendency of rotating, and the head of H-shaped scraper 2 is contacted with conveying belt 1 by the tendency of rotating.When slurry is spilled on conveying belt 1, with the operation of conveying belt 1, H-shaped scraper 2 contacted with conveying belt 1 can scrape slurry on conveying belt 1, so that conveying belt 1 keeps clean, avoid the appearance of gypsum board lower paper surface sticking slurry, improve gypsum board yield, reduce production cost.

[0027] Further, tensioning mechanism includes first threaded rod 6, spring 7 and connection plate 8;

[0028] One end of connection plate 8 is fixedly connected with rotating holder shaft 4, and the other end is provided with through hole sleeved on the outside of first threaded rod 6, and the diameter of through hole is greater than the diameter of first threaded rod 6;

[0029] The tail end of the first threaded rod 6 is fixedly connected to the equipment support 5, and the tail end of the first threaded rod 6 is connected with a first adjusting nut 9, the spring 7 is arranged between the connecting plate 8 and the first adjusting nut 9, and the head of the first threaded rod 6 is further connected with a second adjusting nut 10, and the second adjusting nut 10 is in abutment with the connecting plate 8.

[0030] If the head of the H-shaped scraper 2 wants to rotate away from the conveying belt 1, the connecting plate 8 connected with the rotating tool holder shaft 4 needs to compress the spring 7, so that the head of the H-shaped scraper 2 can be kept in abutment with the surface of the conveying belt 1 by the elastic force of the spring 7.

[0031] By rotating the first adjusting nut 9, the first adjusting nut 9 can compress the spring 7, so that the tension of the spring 7 on the H-shaped scraper 2 is increased, and the difficulty of the head of the H-shaped scraper 2 being separated from the conveying belt 1 is increased.

[0032] Since the diameter of the through hole of the connecting plate 8 is greater than the diameter of the first threaded rod 6, when the second adjusting nut 10 is rotated to move close to the first adjusting nut 9, the connecting plate 8 can be moved to the position of the first adjusting nut 9, so that the H-shaped scraper 2 is separated from the conveying belt 1. Conversely, when the second adjusting nut 10 is moved away from the first adjusting nut 9, the connecting plate 8 can be moved away from the first adjusting nut 9, so that the H-shaped scraper 2 abuts against the conveying belt 1.

[0033] It can be understood that the tensioning mechanism can also be directly provided as an air cylinder, and the two ends of the air cylinder are respectively hinged with the connecting plate 8 and the equipment rack, and by the extension and contraction of the air cylinder, the rotating tool holder shaft is controlled to rotate forward or reversely, so that the H-shaped scraper 2 abuts against or separates from the conveying belt 1.

[0034] Further, the slurry spilled at the head of the gypsum board can also be adhered to the belt pulley at the starting end of the second control section, causing the belt to deviate, and therefore the utility model also provides a pulley scraper 11, which is as follows:

[0035] The inner side of the starting end of the conveying belt 1 is provided with the pulley scraper 11, the head of the pulley scraper 11 is in abutment with the belt pulley at the starting end of the conveying belt 1, and the installation mode of the pulley scraper 11 is the same as that of the H-shaped scraper 2. The pulley scraper 11 can scrape off the slurry on the belt pulley, avoiding the deviation of the conveying belt 1.

[0036] Further, in order to ensure that the slurry on the conveying belt 1 is completely removed, the utility model adds a P-shaped scraper 12 on the basis of the H-shaped scraper 2, that is, the H-shaped scraper 2 is used for primary cleaning, and the P-shaped scraper 12 is used for secondary cleaning, which is as follows:

[0037] The P-shaped scraper 12 is fixedly installed on the lifting scraper shaft 13 through a scraper shaft, and the two ends of the lifting scraper shaft 13 are connected with a lifting mechanism. The lifting mechanism can drive the P-shaped scraper 12 to move up and down, so that the P-shaped scraper 12 is in contact with or away from the conveying belt 1.

[0038] The head of the P-shaped scraper 12 is vertically in contact with the conveying belt 1, and the scraping effect on the slurry is better.

[0039] Further, the lifting mechanism includes a second threaded rod 14, and the upper end of the second threaded rod 14 is fixedly connected with the lifting scraper shaft 13. The second threaded rod 14 is fixedly installed on the equipment support 5 through two fixed nuts 15.

[0040] When the height of the P-shaped scraper 12 needs to be adjusted, the two fixed nuts 15 are loosened, then the position of the second threaded rod 14 is moved up and down, and then the two fixed nuts 15 are tightened to fix the second threaded rod 14 on the platform of the equipment rack.

[0041] It can be understood that the lifting mechanism can be directly provided as an air cylinder, and the P-shaped scraper 12 is controlled to rise or fall through the extension and retraction of the air cylinder.

[0042] Further, the scraper holder 3 includes an insertion plate 16 fixedly installed on the rotating scraper shaft 4 or the lifting scraper shaft 13. The insertion plate 16 is inserted into a slot of the H-shaped scraper 2 or the P-shaped scraper 12, and a bolt 17 penetrates the insertion plate 16 and the scraper to fixedly connect the scraper with the insertion plate 16.
