Description

Technical Field

[0001] This application relates to the field of granite processing technology, and in particular to a granite surface cleaning device. Background Technology

[0002] Granite slabs are a type of building and decorative material, primarily composed of a combination of various raw materials. After molding, granite slabs typically have a large amount of stone powder and other impurities adhering to their surface, requiring surface cleaning before further processing.

[0003] A cleaning device has been proposed in related technologies, including a conveyor frame, a gantry frame, a brush roller, and a motor. The gantry frame is mounted on the conveyor frame, and the motor is horizontally mounted on the gantry frame. The brush roller is connected to the motor's rotating shaft, and a gap is left between the brush roller and the conveyor frame for the stone to pass through. The stone is placed on the conveyor frame and transported. When it passes the bottom of the brush roller, the motor is started to drive the brush roller to rotate, thereby cleaning the surface of the granite slab.

[0004] The aforementioned technologies have a fixed spacing between the brush roller and the conveyor frame, making them unsuitable for cleaning the surface of granite slabs of different thicknesses. They are not very applicable and can only clean one side of the slab per unit time, resulting in low efficiency. Utility Model Content

[0005] To address the issues of limited applicability, low efficiency, and the inability to clean only one side of a granite slab per unit time due to the fixed spacing between the brush roller and the conveyor frame, this application provides a granite surface cleaning device.

[0006] The granite surface cleaning equipment provided in this application adopts the following technical solution:

[0007] A granite surface cleaning device includes a conveyor frame, mounting bases, an upper cleaning roller, and a lower cleaning roller. The conveyor frame has conveyor rollers rotatably connected to it along its width, and multiple conveyor rollers are spaced apart along the length of the conveyor frame. The mounting bases are located at both ends of the conveyor frame along its width, and the two ends of the lower cleaning roller are respectively connected to the two mounting bases. The top of the lower cleaning roller is flush with the top of the conveyor rollers. Sliding seats are slidably connected vertically to the mounting bases, and the two ends of the upper cleaning roller are rotatably connected to the two sliding seats. The mounting base is equipped with an adjustment mechanism for adjusting the height of the sliding seats and a drive mechanism for synchronously driving the upper and lower cleaning rollers to rotate.

[0008] By adopting the above technical solution, the conveyor rollers on the conveyor frame can rotate around their own width. Multiple conveyor rollers are spaced apart along the length of the conveyor frame, enabling the conveying of granite slabs. The lower cleaning roller is connected to the mounting base and its top is flush with the top of the conveyor roller. The upper cleaning roller is connected to the mounting base through a sliding seat and its height can be adjusted by an adjustment mechanism, allowing the upper and lower cleaning rollers to adapt to granite slabs of different thicknesses. The drive mechanism can synchronously drive the upper and lower cleaning rollers to rotate, cleaning the upper and lower surfaces of the granite slabs conveyed between the upper and lower cleaning rollers. This improves upon the problems of existing technologies where the distance between the brush roller and the conveyor frame is fixed, making it difficult to apply to the surface cleaning of granite slabs of different thicknesses, resulting in low applicability and low efficiency, as only one side of the slab can be cleaned per unit time.

[0009] Optionally, both the upper and lower cleaning rollers have water outlet cavities, and both have water outlet holes on their peripheral walls. Both have elastic sponges fitted onto their peripheral walls. The mounting base has a water-passing block with a water-receiving cavity. Both the upper and lower cleaning rollers are inserted into the water-passing block and communicate with the water-receiving cavity. The bottom of the conveyor frame has a water pump, and the outlet of the water pump is connected to the water-receiving cavity of the water-passing block through a pipe.

[0010] By adopting the above technical solution, the water pump delivers water from the bottom of the conveyor frame to the pipeline, and then the water is delivered to the water-receiving cavity of the water-passing block. Since the upper and lower cleaning rollers are both inserted into the water-passing block and connected to the water-receiving cavity, the water enters the water outlet cavity of the upper and lower cleaning rollers, and then flows out through the water outlet holes opened on the peripheral wall to the elastic sponge sleeved on the peripheral wall. During the process of the drive mechanism driving the upper and lower cleaning rollers to rotate, the elastic sponge contacts and rolls with the granite surface, thereby wetting and cleaning the granite surface. The cleaning effect is good, and it also saves water resources.

[0011] Optionally, the bottom of the conveyor frame is provided with a water collection tank with an open top. The water collection tank is provided with a water-permeable membrane that divides the water collection tank into a first chamber and a second chamber. The first chamber is located below the conveyor frame, and the water inlet of the water pump is connected to the second chamber through a pipe.

[0012] By adopting the above technical solution, the wastewater generated during cleaning falls from the board into the first chamber of the water collection tank. Impurities are isolated and filtered in the first chamber, while water passes through the permeable membrane into the second chamber. The water pump draws the filtered water from the second chamber, realizing the recycling of water resources and reducing water waste.

[0013] Optionally, the drive mechanism includes a rotary motor, a synchronous pulley, and an elastic synchronous belt. The synchronous pulley is coaxially connected to the upper and lower cleaning rollers, respectively. The elastic synchronous belt is wound around the two synchronous pulleys. The rotary motor is mounted on a mounting base, and the rotating shaft of the rotary motor is connected to the lower cleaning roller.

[0014] By adopting the above technical solution, the rotating motor drives the lower cleaning roller to rotate, and the synchronous wheel on the lower cleaning roller rotates accordingly. Since the elastic synchronous belt is wound around the synchronous wheels of the upper and lower cleaning rollers, the synchronous wheel on the upper cleaning roller will also rotate, thereby realizing the rotation of the upper cleaning roller. This enables the upper and lower cleaning rollers to rotate synchronously, cleaning the granite surface transported between the upper and lower cleaning rollers. Furthermore, since the upper and lower cleaning rollers rotate in the same direction, the frictional forces on the granite slabs cancel each other out, making the transport of granite slabs more stable.

[0015] Optionally, the adjusting mechanism includes an adjusting bolt, which is vertically threaded to the top of the mounting base. The top of the sliding base is provided with a fixed cylinder, and the bottom of the adjusting bolt is provided with a limiting plate, which is locked inside the fixed cylinder.

[0016] By adopting the above technical solution, rotating the adjusting bolt causes it to shift vertically as it is connected to the top of the mounting base via a vertical thread. Since the limiting disc at the bottom of the adjusting bolt is engaged within the fixed cylinder at the top of the sliding seat, the vertical displacement of the adjusting bolt causes the sliding seat to slide vertically on the mounting base, thereby adjusting the height of the upper cleaning roller to accommodate the cleaning needs of materials of different thicknesses. The adjustment mechanism has a simple structure and is easy to use.

[0017] Optionally, the mounting base is connected to a rotating rod at both the top and bottom, and the end of the rotating rod is provided with a scraper. The upper and lower scrapers are respectively used to abut against the upper and lower surfaces of the plate.

[0018] By adopting the above technical solution, when the granite slabs are conveyed by the conveyor frame, the scrapers at the upper and lower ends of the mounting base abut against the upper and lower surfaces of the slabs respectively, which can scrape off the moisture and impurities on the upper and lower surfaces of the slabs and further clean the surface of the slabs.

[0019] Optionally, the rotating rod is rotatably connected to the mounting base, and a tension spring is connected to the rotating rod. The other end of the tension spring is connected to the mounting base, and the tension spring tends to rotate the rotating rod until the scraper abuts against the plate.

[0020] By adopting the above technical solution, the rotating rod is rotatably connected to the mounting base, and tension is provided by the tension spring, so that the scraper can better contact the plate, thereby effectively scraping away residual water stains and impurities on the surface of the plate and improving the cleaning effect of granite surface.

[0021] In summary, this application includes at least one of the following beneficial technical effects:

[0022] 1. The coordinated arrangement of the mounting base, sliding base, upper cleaning roller, lower cleaning roller, adjustment mechanism and drive mechanism enables the cleaning equipment of this application to efficiently clean both sides of granite slabs at the same time, and it is applicable to the cleaning of slabs of different thicknesses. This improves the problem in the prior art that the distance between the brush roller and the conveyor frame is fixed, making it difficult to apply to the surface cleaning of granite slabs of different thicknesses, resulting in low applicability and low efficiency, as only one side of the slab can be cleaned per unit time.

[0023] 2. Water outlet cavities are opened in the upper and lower cleaning rollers and are combined with elastic sponges to allow water to be discharged during cleaning, thereby enhancing the cleaning effect and improving water resource utilization.

[0024] 3. The matching configuration of the rotating motor, synchronous pulley, and elastic synchronous belt allows the upper and lower cleaning rollers to rotate synchronously upon starting the rotating motor, thereby cleaning the granite surface conveyed between the upper and lower cleaning rollers. Furthermore, since the upper and lower cleaning rollers rotate in the same direction, the frictional forces on the granite slabs cancel each other out, resulting in smoother transport of the granite slabs.

Detailed Implementation

[0030] The following is in conjunction with the appendix Figure 1-3 This application will be described in further detail.

[0031] This application discloses a granite surface cleaning device. (Refer to...) Figure 1-2 The granite surface cleaning equipment includes a conveyor frame 1, a mounting base 2, an upper cleaning roller 3, and a lower cleaning roller 4. The conveyor frame 1 is used to transport granite slabs. Specifically, a conveyor roller 11 is rotatably connected to the top of the conveyor frame 1 around its width. Multiple conveyor rollers 11 are spaced apart along the length of the conveyor frame 1. A drive motor for rotating the conveyor rollers 11 can be installed on the conveyor frame 1. The conveyor rollers 11 are typically cylindrical, made of metal or hard plastic, and possess high strength and wear resistance. The conveyor rollers 11 are rotatably connected to the conveyor frame 1 via bearings, ensuring their rotational flexibility. The arrangement of multiple conveyor rollers 11 allows the granite slabs to move stably on the conveyor frame 1, facilitating subsequent cleaning operations.

[0032] Mounting base 2 is bolted to both ends of the conveyor frame 1 in the width direction. Mounting base 2 is generally made of metal, which has good strength and stability and can withstand various forces during the cleaning process. The two ends of the lower cleaning roller 4 are rotatably connected to the two mounting bases 2 through bearings. The top of the lower cleaning roller 4 is flush with the top of the conveyor roller 11. This arrangement ensures that the granite slabs are in full contact with the lower cleaning roller 4 during the conveying process, achieving effective cleaning of the lower surface of the slabs. A sliding groove 21 is horizontally opened on the mounting base 2 and extends vertically. A sliding seat 5 is vertically slidably locked in the groove 21. The sliding seat 5 can be a metal block. The two ends of the upper cleaning roller 3 are rotatably connected to the two sliding seats 5 through bearings. A gap is left between the upper cleaning roller 3 and the lower cleaning roller 4 for the granite slabs to pass through. Both the upper cleaning roller 3 and the lower cleaning roller 4 are fitted with elastic sponges 6, and both the upper cleaning roller 3 and the lower cleaning roller 4 are connected to a water spraying mechanism for spraying water toward the elastic sponges 6. The mounting base 2 is equipped with a drive mechanism for synchronously driving the upper cleaning roller 3 and the lower cleaning roller 4 to rotate, and the mounting base 2 is also equipped with an adjustment mechanism for adjusting the height of the sliding seat 5.

[0033] In use, granite slabs are placed on conveyor rollers 11 for transport. When passing between the upper cleaning roller 3 and the lower cleaning roller 4, water is sprayed onto the elastic sponge 6 via a water spraying mechanism. Simultaneously, a drive mechanism drives both the upper and lower cleaning rollers 3 and 4 to rotate, causing the elastic sponge 6 to rotate and clean the upper and lower surfaces of the granite slabs. This ensures that the granite slabs receive thorough and effective cleaning during transport. Furthermore, the height of the upper cleaning roller 3 can be flexibly adjusted according to the thickness of the granite slab, ensuring close contact between the upper cleaning roller 3 and the upper surface of the slab for optimal cleaning results. This technology overcomes the limitations of existing technologies where the fixed spacing between the brush roller and the conveyor frame makes it difficult to clean granite slabs of varying thicknesses, resulting in limited applicability and low efficiency as only one side of the slab can be cleaned per unit time.

[0034] For example, the drive mechanism includes a rotary motor 22, synchronous pulleys 23, and an elastic synchronous belt 24. The synchronous pulleys 23 are coaxially connected to the upper cleaning roller 3 and the lower cleaning roller 4, respectively. The elastic synchronous belt 24 is wound around the two synchronous pulleys 23. The rotary motor 22 is mounted on the mounting base 2, and the rotating shaft of the rotary motor 22 is connected to the lower cleaning roller 4. The rotary motor 22 is generally a three-phase asynchronous motor, characterized by strong power and stable operation. The synchronous pulleys 23 are made of metal with a special surface treatment to increase the friction between them and the elastic synchronous belt 24, ensuring the effectiveness of transmission. The elastic synchronous belt 24 has a certain degree of elasticity, which can adapt to changes in the distance between the synchronous pulleys 23, and can also buffer the impact force during transmission. When the rotary motor 22 starts, it drives the lower cleaning roller 4 to rotate. Through the transmission of the synchronous pulleys 23 and the elastic synchronous belt 24, the upper cleaning roller 3 also rotates synchronously, realizing the synchronous cleaning of the upper and lower surfaces of the granite slab. Furthermore, since the upper cleaning roller 3 and the lower cleaning roller 4 rotate in the same direction, the frictional forces on the granite slabs cancel each other out, making the transportation of the granite slabs more stable and improving the cleaning effect.

[0035] For example, refer to Figure 3 The adjustment mechanism includes an adjusting bolt 7, which is vertically threaded to the top of the mounting base 2. A fixed cylinder 51 is welded to the top of the sliding seat 5. A limiting plate 71 is provided at the bottom of the adjusting bolt 7, which is engaged within the fixed cylinder 51 and can rotate with the adjusting bolt 7 within the fixed cylinder 51. The adjusting bolt 7 is generally made of high-strength carbon steel with high thread precision, enabling precise height adjustment. The cooperation between the limiting plate 71 and the fixed cylinder 51 ensures that the adjusting bolt 7 can drive the sliding seat 5 to move up and down when rotating, without relative rotation. When it is necessary to adjust the height of the upper cleaning roller 3, rotating the adjusting bolt 7 causes the sliding seat 5 to slide up and down on the mounting base 2 via the limiting plate 71, thereby adjusting the height of the upper cleaning roller 3. The adjustment mechanism has a simple structure and is easy to use.

[0036] For example, refer to Figure 1 and Figure 2 The water spraying mechanism includes a water-passing block 25 and a water pump 8. The water-passing block 25 is bolted and fixed to the mounting base 2. A water-containing cavity 251 is formed inside the water-passing block 25. The outlet of the water pump 8 is connected to the water-containing cavity 251 of the water-passing block 25 through a pipe, and the inlet of the water pump 8 is connected to a water source. Both the upper cleaning roller 3 and the lower cleaning roller 4 have water outlet cavities 31. Water outlet holes 32 are formed on the peripheral walls of both the upper cleaning roller 3 and the lower cleaning roller 4. Both the upper cleaning roller 3 and the lower cleaning roller 4 are inserted into the water-passing block 25 and are connected to the water-containing cavity 251. The water pump 8 delivers water to the water-receiving cavity 251 of the water block 25, and then the water enters the water outlet cavity 31 of the upper cleaning roller 3 and the lower cleaning roller 4 through the water-receiving cavity 251. Finally, the water flows out from the water outlet 32 ​​onto the elastic sponge 6. The elastic sponge 6 has good water absorption and water retention properties, and can store the water flowing out from the water outlet 32, so as to achieve wetting and efficient cleaning of the granite slabs and high water resource utilization.

[0037] Furthermore, the bottom of the conveyor frame 1 is equipped with a water collection tank 9 with an open top. Inside the water collection tank 9, a permeable membrane 91 divides the tank into a first chamber and a second chamber. The first chamber is located below the conveyor frame 1, and the inlet of the water pump 8 is connected to the second chamber via a pipe. The water collection tank 9 is generally made of plastic, which is corrosion-resistant and lightweight. The permeable membrane 91 can be a filter cloth or a filter screen, capable of filtering impurities in the water and ensuring the cleanliness of the water entering the water pump 8. Wastewater generated during the cleaning process flows into the first chamber, is filtered by the permeable membrane 91, enters the second chamber, and is then pumped back into the cleaning system by the water pump 8, achieving water recycling and reducing water waste and cleaning costs.

[0038] In addition, rotating rods 26 are rotatably connected to both the top and bottom of the mounting base 2. A scraper 27 is located at the end of the rotating rod 26, and a tension spring 28 is connected to the rotating rod 26. The other end of the tension spring 28 is connected to the mounting base 2, and the tension spring 28 tends to rotate the rotating rod 26 until the scraper 27 abuts against the granite slab. The scraper 27 is made of rubber, which has good flexibility and wear resistance, effectively removing water stains and residual dirt from the surface of the granite slab. The tension spring 28 ensures that the scraper 27 is always in close contact with the surface of the granite slab, improving the scraping effect.

[0039] The implementation principle of this embodiment is as follows: During use, granite slabs are transported on conveyor rollers 11. Water pump 8 pumps water from the second chamber of water collection tank 9 into the water-receiving cavity 251 of water block 25 through a pipe. After entering the water outlet cavity 31 of the upper cleaning roller 3 and lower cleaning roller 4, the water enters the elastic sponge 6 through the water outlet hole 32. The rotating motor 22, driven by the synchronous pulley 23 and elastic synchronous belt 24, synchronously drives the upper cleaning roller 3 and lower cleaning roller 4 to rotate at high speed, thereby achieving efficient cleaning of both the upper and lower surfaces of the granite slabs simultaneously by the water-filled elastic sponge 6. Furthermore, by rotating the adjusting bolt 7, the sliding seat 5 can be raised and lowered, thereby adjusting the distance between the upper cleaning roller 3 and lower cleaning roller 4 to adapt to the cleaning operation of granite slabs of different thicknesses. This improves upon the problems of the existing technology where the distance between the brush roller and the conveyor frame is fixed, making it difficult to apply to the surface cleaning of granite slabs of different thicknesses, resulting in low applicability and low efficiency as only one side of the slab can be cleaned per unit time.

[0040] The above are all optional embodiments of this application and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
