The slurry leaked from the gypsum board head is easy to stick to the surface of the flat belt of the second control section. After the flat belt rotates one circle, the slurry on the surface of the flat belt will stick to the lower paper surface of the next section of incoming gypsum board, thus producing defective gypsum board, increasing production costs and reducing production efficiency. Summary of the invention

[0008] As a preferred solution of the present invention, rotating rods are installed on both sides of the adsorption head in the moving direction of the conveyor belt to separate the adsorption head and the adsorption surface from the conveyor belt and maintain a fixed distance.

[0012] The second nozzle is arranged upstream of the adsorption head, and the spraying direction of the second nozzle is perpendicular to the surface of the conveyor belt to wet the slurry adhered to the surface of the conveyor belt.

[0013] As a preferred solution of the present invention, a box cover is provided at the upper end of the material collection box, and the box cover is fixedly installed on the equipment frame. A notch is provided on the upper part of the material collection box for the conveyor belt to pass through;

DETAILED DESCRIPTION

[0028] The following will be combined with the 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 described embodiments 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 creative work are within the scope of protection of the present invention.

[0029] The present invention specifically provides a composite conveyor belt slurry cleaning device, comprising:

[0030] A collection box 1 is arranged below the conveyor belt 2 and is used to collect the cleaned slurry 4;

[0031] The scraper 5 is rotatably installed in the collecting box 1 through a rotating shaft, and is used to scrape the slurry 4 on the surface of the conveyor belt 2, and the two side surfaces of the blade head of the scraper 5 are connected to the inner wall of the collecting box 1 through a tension spring 6, so that the blade head of the scraper 5 keeps in contact with the conveyor belt 2;

[0032] The adsorption head 7 and the suction pump 8 are both fixedly installed in the collecting box 1 , and the adsorption head 7 is located downstream of the scraper 5 to suck the residual slurry on the conveyor belt 2 .

[0033] When the slurry 4 is spilled on the conveyor belt 2, as the conveyor belt 2 runs, the scraper 5 in contact with the surface of the conveyor belt 2 will scrape off most of the slurry 4. When the conveyor belt 2 passes through the adsorption head 7, a small amount of slurry 4 remaining on the conveyor belt 2 that cannot be scraped off by the scraper 5 and adheres to the surface of the conveyor belt 2 will be separated from the conveyor belt 2 under the action of the strong suction force of the adsorption head 7, thereby achieving the purpose of completely removing the slurry 4 on the conveyor belt 2, avoiding the slurry 4 sticking to the paper surface of the gypsum board 3 from a controlled flow, thereby improving the yield rate and reducing production costs.

[0034] A sewage outlet (not shown) is arranged at the lower end of the aggregate box 1 .

[0035] Furthermore, rotating rods 9 are installed on both sides of the adsorption head 7 in the moving direction of the conveyor belt 2 to separate the adsorption head 7 and the adsorption surface from the conveyor belt 2 and maintain a fixed distance.

[0036] The reason for maintaining a certain distance is that if the adsorption head 7 is completely covered by the conveyor belt 2 , the adsorption head 7 and the conveyor belt 2 will adhere together due to the pressure difference, affecting the operation of the conveyor belt 2 .

[0037] Furthermore, by rotating the rod 9 to contact the conveyor belt 2 , the sliding friction between the adsorption head 7 and the conveyor belt 2 can be converted into rolling friction, thereby weakening the influence of the adsorption head 7 on the operation of the conveyor belt 2 .

[0038] Furthermore, according to the principle that the more diluted the slurry 4 is, the easier it is to separate from the conveyor belt 2, a first nozzle 10 is fixedly installed in the aggregate box 1, and the first nozzle 10 is connected to a water pump arranged outside the aggregate box 1 through a water pipe and a water pipe joint;

[0039] The first nozzle 10 is disposed upstream of the scraper 5 , and the nozzle is inclined toward the blade head of the scraper 5 to wet the slurry 4 and clean the scraper 5 .

[0040] By spraying water onto the blade head of the scraper 5 through the first nozzle 10, the slurry 4 can be moistened on the one hand, so that the slurry 4 on the conveyor belt 2 can be more easily removed; on the other hand, the high-pressure water can also directly wash away a portion of the slurry 4; and the high-pressure water can also continuously rinse the blade head to prevent the slurry 4 from wrapping around the blade tip, so that the blade head maintains a strong scraping ability; the cleaned water flows down along the blade head and can also clean the blade body to prevent the slurry 4 from clogging up on the scraper 5.

[0041] Furthermore, during actual use, although the scraper 5 can scrape off most of the slurry 4, a thin layer of slurry 4 will still remain on the surface of the conveyor belt 2, and after being squeezed and applied by the scraper 5, the adsorption force between the thin layer of slurry 4 and the conveyor belt 2 is stronger, resulting in the adsorption head 7 sucking and cleaning the slurry 4 layer. The suction force required is extremely large, and the cleaning may not be thorough.

[0042] To this end, the present invention further has a second nozzle 11 fixedly installed in the aggregate box 1, and the second nozzle 11 is connected to the water pump through a water pipe and a water pipe joint;

[0043] The second nozzle 11 is disposed upstream of the adsorption head 7 , and the spraying direction of the second nozzle 11 is perpendicular to the surface of the conveyor belt 2 so as to wet the slurry 4 adhered to the surface of the conveyor belt 2 .

[0044] The water flow vertically sprayed by the second nozzle 11 toward the conveyor belt 2 can directly dilute the slurry 4 layer, so that the slurry 4 with a higher density becomes slurry 4 water, and then the slurry 4 water enters the adsorption head 7 under the suction force of the adsorption head 7, and is discharged into the collection box 1 by the suction pump 8. Among them, the vertically sprayed water flow can more easily flush out the slurry 4 embedded in the surface defects of the conveyor belt 2 (such as the small pits on the surface of the conveyor belt 2). The slurry 4 embedded in the surface defects cannot be cleaned by the scraper 5, and can only be cleaned by the adsorption head 7.

[0045] Furthermore, a box cover 12 is provided at the upper end of the aggregate box 1, and the box cover 12 is fixedly mounted on the equipment frame. A notch 13 is provided at the upper part of the aggregate box 1 for the conveyor belt 2 to pass through; when cleaning the slurry 4, the box cover 12 fits with the aggregate box 1 to prevent the water slurry from splashing outward, thereby ensuring the cleanliness of the working environment;

[0046] The material collecting box 1 is fixedly mounted on the cylinder 14 and can rise or fall under the drive of the cylinder 14. When not in operation, the cylinder 14 contracts and the material collecting box 1 is away from the conveyor belt 2, so that the conveyor belt 2 or the equipment can be adjusted and repaired easily.

[0047] During operation, the cylinder 14 extends, the collecting box 1 moves upward, and the scraper 5 and the rotating rod contact the conveyor belt 2.

[0048] Furthermore, considering that the first nozzle 10 and the second nozzle 11 spray high-pressure water to the conveyor belt 2, the conveyor belt 2 will vibrate up and down, and if the vibration is transmitted to the starting end of the conveyor belt 2, the slurry 4 newly sprinkled on the starting end of the conveyor belt 2 may spread outward, and even spread to the lower surface of the gypsum board 3 on the conveyor belt 2. For this reason, the present invention is provided with a stabilizing component 15 downstream of the collecting box 1, and the stabilizing component 15 can generate elastic resistance to the vibrating or shaking conveyor belt 2 to reduce the vibration amplitude of the conveyor belt 2.

[0049] Furthermore, a plurality of stabilizing components 15 are arranged downstream of the aggregate box 1, the plurality of stabilizing components 15 are equidistant from the conveyor belt 2, and the elastic coefficients of the plurality of stabilizing components 15 gradually decrease in the direction away from the aggregate box 1, so that the vibration amplitude of the conveyor belt 2 gradually decreases.

[0050] The stabilizing component 15 can generate elastic resistance to the vibrating or shaking conveyor belt 2, and the distances between the multiple stabilizing components 15 and the conveyor belt 2 are equal. The elastic coefficients of the multiple stabilizing components 15 gradually decrease in the direction away from the aggregate box 1, so that the vibration amplitude of the conveyor belt 2 gradually decreases to avoid the vibration from being transmitted to the starting end of the conveyor belt 2.

[0051] Furthermore, the stabilizing assembly 15 includes two rollers 16 disposed on the upper and lower sides of the conveyor belt 2, the rollers 16 are in contact with the conveyor belt 2, the rollers 16 are mounted on a roller frame 17, and the roller frame 17 is mounted on a stand 18 through an elastic telescopic member;

[0052] Furthermore, the elastic coefficients of the elastic telescopic parts in the plurality of stabilizing components 15 gradually decrease in the direction away from the cleaning mechanism.

[0053] When the conveyor belt 2 vibrates, the conveyor belt 2 will drive the roller 16 in contact with it to move synchronously, compress the elastic member through the roller 16, and use the resistance and resilience generated by the elastic member to quickly reduce the vibration amplitude.

[0054] Since the roller 16 is rotatable, the roller 16 can be made to contact the conveyor belt 2 without causing any adverse effect on the conveyor belt 2 . The contact of the roller 16 with the conveyor belt 2 can increase the response speed of the stabilizing component 15 .

[0055] Furthermore, the elastic telescopic member includes a telescopic rod 19 whose two ends are respectively fixedly connected to the roller frame 17 and the vertical frame 18 , and a compression spring 20 is disposed on the outer sleeve of the telescopic rod 19 .

The protection scope of the present application is defined by the claims. Those skilled in the art may make various modifications or equivalent substitutions to the present application within the essence and protection scope of the present application, and such modifications or equivalent substitutions shall also be deemed to fall within the protection scope of the present application.
