Description

Technical Field

[0001] The present application relates to the technical field of stone processing, and in particular to a stone protective agent roller coating machine. Background Art

[0002] Stone protective agent is a liquid specially used to protect stone. It is mainly composed of solution (active ingredient), solvent (diluent), and a small amount of additives. The basic function is to brush, spray, apply, roll, pour and soak. The protective agent is evenly distributed on the surface of the stone or penetrates into the inside of the stone, thus forming a kind of protection. This protection makes the stone waterproof, anti-fouling, acid and alkali resistant, anti-aging, anti-freeze and thaw, thereby improving the service life of the stone and the decorative performance of the stone.

[0003] Protective agents can be used during the processing of stone to ensure that the stone has better durability and beauty in subsequent use. At the same time, stone protective agents can also be used in the daily maintenance of stone. Through regular or irregular maintenance work, the protective effect of the stone can be further enhanced and its service life can be extended.

[0004] Currently, stone protective agent spraying methods mostly use manual brushing or simple spraying equipment. This method is not only inefficient, but also difficult to ensure the uniformity and coverage of the protective agent on the stone surface. In addition, the brushing device cannot meet the needs of various stone specifications, resulting in waste of stone protective agent. Therefore, the present application provides a stone protective agent roller coating machine. Utility Model Content

[0022] The present application is further described in detail below with reference to the accompanying drawings.

[0023] Example, see Figure 1 、 Figure 2 、 Figure 3 and Figure 4, A stone protective agent roller coater, comprising a frame 1 and a conveyor belt 2 installed on the frame 1. A cleaning device 3, a protective agent storage device 4 and a roller coating device 5 are installed on the frame 1. The roller coating device 5 includes a U-shaped roller coating bracket 50. The U-shaped roller coating bracket 50 is installed on the frame 1 and is located above the conveyor belt 2. A roller coating motor 51 is installed at one end of the U-shaped roller coating bracket 50 away from the conveyor belt 2. The output end of the roller coating motor 51 passes through the U-shaped roller coating bracket 50 and is located above the conveyor belt 2. A driving gear 52 is fixedly installed at the output end of the roller coating motor 51. A driven gear 53 is meshed with the driving gear 52. One side of the driven gear 53 is rotatably connected to the U-shaped roller coating bracket 50. A roller coater 54 capable of adapting to stones of different sizes is fixedly installed on the other side of the driven gear 53. The other end of the roller coater 54 is rotatably connected to an adjusting plate 55 (here, the rotational connection between the roller coater 54 and the adjusting plate 55 can also be a direct rotational connection or achieved through other components, and can be freely selected according to the actual situation. For example, bearings are directly installed on the roller coater 54 and the adjusting plate 55, etc.). The other end of the adjusting plate 55 is slidably connected to the upper end of the U-shaped roller coating bracket 50. One side of the adjusting plate 55 away from the roller coater 54 is connected to an adjusting rod 56. The adjusting rod 56 passes through one end of the U-shaped roller coating bracket 50 away from the adjusting plate 55 and is threadedly connected to the U-shaped roller coating bracket 50.

[0024] Specifically, the roller coater 54 includes an elastic roller coating cylinder 540 and a roller coating layer 541 installed on the outside of the elastic roller coating cylinder 540.

[0025] The elastic roller coating cylinder 540 is preferably a spring, and the roller coating layer 541 is preferably a sponge.

[0026] During actual work, according to the size of the stone, rotate the adjusting rod 56. Since the adjusting rod 56 is threadedly connected to the adjusting plate 55, while rotating the adjusting rod 56, the adjusting plate 55 pushes the elastic roller coating cylinder 540 to be compressed and then changes the length of the elastic roller coating cylinder 540 itself, so as to adapt to the size of the stone. When roller coating the protective agent on the surfaces of different stones, since the elastic roller coating cylinder 540 can be adjusted by itself, compared with the case where the roller coating cylinder cannot adjust its own length, waste of the protective agent is saved.

[0027] In the embodiment of the present disclosure, in order to maintain the length of the adjusted elastic roller coating barrel 540 during operation, a long strip-shaped through hole is opened at the upper end of the U-shaped roller coating bracket 50, and the upper end of the adjustment plate 55 is placed in the through hole. The upper end of the adjustment plate 55 is fixedly mounted with a horizontal plate 550, and the horizontal plate 550 is fixedly mounted with a vertical plate 551. The inner surface of the vertical plate 551 is clamped to the surface of the U-shaped roller coating bracket 50. The vertical plate 551 is provided with a threaded hole, and the threaded hole is threaded with a bolt 552. When the size of the stone is confirmed, by rotating the adjustment rod 56, the adjustment rod 56 pushes the adjustment plate 55 and thus adjusts the elastic roller coating barrel 540 to the same size as the stone. Then, the bolt 552 is tightened. The bolt 552 firmly connects the adjustment plate 55 and the U-shaped roller coating bracket 50 to prevent the elastic roller coating barrel 540 from changing its length during operation.

[0028] In the embodiment of the present disclosure, the protective agent storage device 4 includes a liquid storage cylinder 40 and a liquid outlet pipe 41 installed on the liquid storage cylinder 40. The other end of the liquid outlet pipe 41 is connected to a high-pressure pump 42, and the liquid outlet of the high-pressure pump 42 is connected to a high-pressure pipe 43. The other end of the high-pressure pipe 43 is installed with a protective agent nozzle 44, and the protective agent nozzle 44 is arranged in the elastic roller coating cylinder 540.

[0029] Specifically, the high-pressure pump 42 is preferably a plunger pump.

[0030] Specifically, the protective agent nozzle 44 is provided with a plurality of nozzles, and the spraying directions of the plurality of protective agent nozzles are different.

[0031] In an embodiment of the present disclosure, the cleaning device 3 includes a pair of cleaning brackets 30, which are installed on the frame 1 and located on both sides of the conveyor belt 2. The pair of cleaning brackets 30 are installed with a connecting plate 31. A roller brush 32 is rotatably connected between the pair of cleaning brackets 30, and the roller brush 32 is located below the connecting plate 31. A roller motor 33 is fixedly installed at one end of the roller brush 32, and the roller motor 33 is fixedly installed on the frame 1.

[0032] A cleaning nozzle 34 is mounted on the connecting plate 31 , an air inlet of the cleaning nozzle 34 is connected to an air inlet pipe 35 , and the other end of the air inlet pipe 35 is connected to an air pump 36 . There are multiple cleaning nozzles 34 , all of which face the roller brush 32 .

[0033] In the specific implementation process, according to the size of the stone, rotate the adjusting rod 56. The adjusting rod 56 pushes the adjusting plate 55, and then adjusts the elastic roller coating cylinder 540 to be the same size as the stone. Then tighten the bolt 552. The bolt 552 fixes the adjusting plate 55 and the U-shaped roller coating bracket 50 together. Start the roller coating motor 51, the roller motor 33, the high-pressure pump 42 and the air pump 36. Place the stone on the conveyor belt 2. During the conveying process of the stone, the roller motor 33 drives the roller brush 32 to clean the surface of the stone. At the same time, the air pump 36 conveys high-pressure gas through the cleaning nozzle 34 to clean the surface of the stone. During the conveying process of the cleaned stone on the conveyor belt 2, the high-pressure pump 42 sprays the protective agent into the elastic roller coating cylinder 540. The roller coating motor 51 drives the elastic roller to rotate, and performs protective agent roller coating on the stone on the conveyor belt 2.

[0034] The embodiments of this specific implementation manner are all preferred embodiments of this application, and do not limit the protection scope of the application accordingly. Therefore, all equivalent changes made according to the structure, shape, and principle of this application shall be covered within the protection scope of this application.
