Description

Technical Field

[0001] This utility model relates to the technical field of ceramic tile bottom washing machines, specifically a reciprocating bottom washing machine. Background Technology

[0002] In the traditional tile processing industry, tile bottom cleaning machines are key pieces of equipment, undertaking the important task of cleaning the bottom of tiles. Their core working principle typically relies on one or more sets of rollers. The rotation of the rollers moves the tiles, and the friction between the roller surface and the tile bottom removes impurities, stains, or residues, achieving the purpose of cleaning.

[0003] However, after prolonged and intensive cleaning, the middle section of the roller often experiences significant wear due to the increased pressure and friction, resulting in what is known as "bottoming out." This means the surface material of the middle section of the roller is worn away, exposing the underlying metal or harder material. This not only reduces cleaning effectiveness but can also scratch or damage the bottom of the tiles.

[0004] Meanwhile, the ends of the roller experience relatively less contact with the tiles or less friction, resulting in less wear, or even almost no wear in some cases. This uneven wear phenomenon, where the middle rubs against the bottom while the ends don't, not only shortens the roller's lifespan and increases equipment maintenance costs, but also affects the overall cleaning efficiency and quality of the tile washing machine.

[0037] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "assembly," and "connection" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0038] The following is combined Figures 1 to 6 This describes a reciprocating bottom washing machine according to an embodiment of the present utility model.

[0039] A reciprocating bottom washing machine includes a frame 1. An upper conveying device 2 is provided at the top of the frame 1, and a lower conveying device 3 and a washing device 4 are provided at the bottom of the frame 1. The washing device 4 includes a washing mounting plate 41, a self-rotating component 42, a left and right reciprocating component 43, and a washing roller 44. The lower conveying device 3 includes a plurality of conveying rollers 31, which are arranged side by side at the bottom of the frame 1. The washing rollers 44 are spaced apart between the plurality of conveying rollers 31.

[0040] The bottom of the frame 1 is slidably connected to the cleaning mounting plate 41. The top of the cleaning mounting plate 41 is equipped with the self-rotating component 42, the left-right reciprocating component 43 and the cleaning drum 44. The driving end of the self-rotating component 42 is fixedly connected to the cleaning drum 44. The left-right reciprocating component 43 is used to drive the cleaning drum 44 to reciprocate in the left-right direction.

[0041] The conveying roller 31 is used to convey materials at the bottom of the frame 1, the upper conveying device 2 is used to convey materials at the top of the frame 1, and the cleaning roller 44 is used to clean the bottom wall of the materials.

[0042] An upper conveyor 2 is installed above the material, and a lower conveyor 3 is installed below the material. When both the upper and lower conveyors 2 and 3 are activated simultaneously, they apply forces from both the top and bottom of the material, clamping and conveying it backward. This material clamping and conveying method can more stably control the movement of the material, avoiding deviation, shaking, or even falling during the conveying process, greatly improving the stability and reliability of material conveying.

[0043] The cleaning device 4 is located at the bottom of the material. The rotating component 42 drives the cleaning drum 44 to rotate rapidly around its own axis, generating strong friction and scrubbing action on the bottom wall of the material. This allows it to penetrate deep into the tiny crevices and textures of the material's bottom wall, effectively removing stubborn stains, oil, rust, and other impurities. Simultaneously, the reciprocating component 43 drives the cleaning drum 44 to reciprocate in the left-right direction, further expanding the cleaning range of the cleaning drum 44 and ensuring that different areas of the material's bottom wall are cleaned evenly and thoroughly.

[0044] By combining rotation and reciprocating motion in the cleaning process, not only is comprehensive and deep cleaning of the bottom wall of the material achieved, greatly improving the cleaning effect, but the cleaning roller also wears more evenly, solving the problem of severe local wear caused by the unidirectional movement of the traditional cleaning roller 44.

[0045] The left and right reciprocating assembly 43 includes left and right movable plates 431 and left and right reciprocating power components 432. The left and right movable plates 431 are slidably connected to the top of the cleaning mounting plate 41. The left and right reciprocating power components 432 are mounted on the cleaning mounting plate 41. The driving end of the left and right reciprocating power components 432 is fixedly connected to the left and right movable plates 431. The movement direction of the left and right reciprocating power components 432 is the left and right direction.

[0046] The self-rotating component 42 and the cleaning roller 44 are mounted on the left and right movable plates 431.

[0047] It is worth noting that the left-right reciprocating power component 432 is a cylinder. When the left-right reciprocating power component 432 is activated, it drives the left and right movable plates 431 to slide back and forth in the left-right direction. Since both the self-rotating component 42 and the cleaning roller 44 are mounted on the left and right movable plates 431, it is ensured that the cleaning roller 44 has the ability to perform both left-right reciprocating motion and self-rotation.

[0048] The left and right movable plates 431 are slidably connected to the cleaning mounting plate 41, which not only limits the movement direction of the left and right movable plates 431, but also reduces the friction and shaking of the left and right movable plates 431 during the movement, making the movement of the cleaning roller 44 more precise in the left and right direction, which is conducive to uniform and effective cleaning of the bottom of the material.

[0049] The self-rotating assembly 42 includes a self-rotating power component 421 and a mounting bearing 422. The mounting bearing 422 is mounted on the left and right movable plates 431. The left and right ends of the cleaning roller 44 are respectively connected to the mounting bearing 422. The driving end of the self-rotating power component 421 is fixedly connected to the cleaning roller 44. The self-rotating power component 421 is mounted on the left and right movable plates 431.

[0050] In this embodiment, the rotation power component 421 is a servo motor. The rotation power component 421 is directly mounted on the left and right movable plates 431, and its drive end is fixedly connected to the cleaning drum 44. This ensures that the rotation of the cleaning drum 44 is not disturbed by the movement of other components, allowing for stable and continuous rotation. During the cleaning process, the rotation power component 421 provides continuous power to the cleaning drum 44, ensuring that the cleaning drum 44 rotates at a constant speed, thereby achieving uniform and effective cleaning of the bottom of the material.

[0051] The mounting bearing 422 can securely mount the cleaning roller 44 on the left and right movable plates 431. The mounting bearing 422 can provide low-friction, high-precision support for the rotation of the cleaning roller 44, enabling the cleaning roller 44 to rotate flexibly during its rotation, reducing energy loss and heat accumulation caused by friction, and improving the efficiency and stability of rotation.

[0052] refer to Figure 6 This is a simplified schematic diagram of the cleaning device 4. It is worth noting that the area between the two mounting bearings 422 is the passageway for the tile. To ensure that the cleaning roller 44 can clean the bottom wall of the tile, the passageway is much larger than the length / width of the tile.

[0053] The cleaning device 4 also includes a lifting power component 45 and a lifting frame 46. The lifting frame 46 is installed at the bottom of the frame 1 and is slidably connected to the cleaning mounting plate 41. The driving end of the lifting power component 45 is fixedly connected to the bottom wall of the cleaning mounting plate 41. The moving direction of the cleaning mounting plate 41 is vertical.

[0054] The lifting power component 45 is a cylinder. When the lifting power component 45 is activated, it can precisely drive the cleaning mounting plate 41 to slide vertically along the lifting frame 46, ensuring that the cleaning roller 44 can contact the bottom wall of the material, thereby achieving the effect of cleaning the bottom wall of the material.

[0055] Because the cleaning mounting plate 41 can be raised and lowered, this reciprocating bottom washing machine can be flexibly adjusted according to the height of different materials. Whether the materials are tall or short, the height of the cleaning mounting plate 41 can be adjusted to maintain a suitable distance between the cleaning roller 44 and the bottom of the material, thereby achieving the best cleaning effect and improving the versatility and adaptability of the equipment.

[0056] The upper conveying device 2 includes an upper conveying power component 21, an upper conveying rotating shaft 22, a pulley 23, and a belt 24;

[0057] The top of the frame 1 is provided with an upper conveyor mounting plate 29. Two upper conveyor mounting plates 29 are respectively installed at the front and rear ends of the frame 1. The upper conveyor mounting plate 29 is rotatably mounted with an upper conveyor rotating shaft 22. The length direction of the upper conveyor rotating shaft 22 is the left and right direction. Multiple pulleys 23 are fixedly sleeved on the upper conveyor rotating shaft 22. Multiple belts 24 are provided. The belts 24 are sleeved on two pulleys 23 that are arranged opposite each other in the front and rear direction. Multiple belts 24 are arranged side by side.

[0058] The upper conveying power component 21 is disposed on one of the upper conveying mounting plates 29, and the driving end of the upper conveying power component 21 is fixedly connected to one of the upper conveying rotating shafts 22.

[0059] In this embodiment, the upper conveying power component 21 is a motor. When the upper conveying power component 21 is started, it can drive the upper conveying rotating shaft 22 on the same side to rotate. The upper conveying rotating shaft 22 drives the fixedly sleeved pulley 23 to rotate. The rotation of the pulley 23 drives the belt 24 to rotate, thereby making the oppositely arranged pulley 23 and the upper conveying rotating shaft 22 rotate synchronously.

[0060] Since the two upper conveyor shafts 22 are respectively set on the front and rear sides of the frame 1, the belt 24 can cover the entire working area on the frame 1. The material located at the front, middle or rear of the frame 1 can be smoothly conveyed by the belt 24.

[0061] Reference Figure 1 The frame 1 is equipped with multiple belts 24, which are arranged in the left and right directions. This effectively extends the conveying range from the traditional middle area to the left and right ends of the frame 1, ensuring that no matter where the material is located in the lateral position of the frame 1, it can be covered and conveyed by at least one belt 24, truly achieving seamless coverage of the conveying.

[0062] The top of the frame 1 has multiple pressure mounting plates 25 arranged in the front-to-back direction. The length direction of the pressure mounting plates 25 is the left-to-right direction. A pressure cylinder 26 is fixedly installed at the bottom of the pressure mounting plate 25. The output end of the pressure cylinder 26 is fixedly connected to the top wall of the pressure beam 20. The bottom of the pressure beam 20 is connected to the top of the wear-resistant plate 28 through a buffer spring 27. The wear-resistant plate 28 is located between the upper belt section and the lower belt section. The bottom wall of the wear-resistant plate 28 abuts against the inner wall of the lower belt section of the belt 24.

[0063] Multiple pressure mounting plates 25 are arranged on the top of the frame 1 in the front-to-back direction and in the left-to-right direction in the length direction. This layout allows the pressure beams 20 and wear-resistant plates 28 to be evenly distributed in the material conveying area.

[0064] The output end of the pressure cylinder 26 is fixedly connected to the pressure beam 20. By controlling the extension and retraction of the pressure cylinder 26, the height of the pressure beam 20 can be precisely adjusted, so that the wear-resistant plate 28 presses down on the belt 24, thereby achieving stable pressing of the material by the belt 24.

[0065] When the belt 24 drives the conveying of materials, the wear-resistant plate 28 can ensure that the lower belt section of the belt 24 is in close contact with the materials, increase the friction of the lower belt section on the materials, effectively counteract various external forces that may affect the materials during the conveying process, thereby preventing the materials from jumping and ensuring the stability of the materials during the conveying process.

[0066] In addition, the buffer spring 27 also serves as a buffer. When materials are subjected to external impacts or vibrate due to their unevenness during the conveying process, the buffer spring 27 can absorb and disperse this energy, reducing the impact force on the materials and equipment and protecting them from damage.

[0067] It is worth noting that the conveyor device 2 in this solution is also equipped with a tensioning structure. The tensioning structure can keep the belt 24 in a uniform tension state on the frame 1, reduce the swaying and shaking of the belt 24, and ensure the stable and efficient operation of the conveying system. The tensioning structure is a common structure and will not be described in detail here.

[0068] The lower conveying device 3 also includes a lower conveying power component 32, a lower conveying drive shaft 33, a lower conveying drive gear 35, and a lower conveying transmission gear 34. The lower conveying drive shaft 33 is rotatably mounted on both the left and right sides of the frame 1. The length direction of the lower conveying drive shaft 33 is the front-to-back direction. Multiple lower conveying drive gears 35 are fixedly sleeved on the lower conveying drive shaft 33. The multiple lower conveying drive gears 35 are arranged opposite to multiple conveying rollers 31. The lower conveying transmission gears 34 are fixedly sleeved on both the left and right ends of the conveying rollers 31. The lower conveying drive gears 35 and the lower conveying transmission gears 34 on the same side mesh with each other. The length direction of the conveying rollers 31 is the left-to-right direction.

[0069] The drive end of the lower conveying power component 32 is fixedly connected to the lower conveying drive shaft 33.

[0070] The lower conveyor power component 32 is a motor. When the lower conveyor power component 32 is started, it transmits power to the lower conveyor drive shaft 33, which is fixedly connected to it. This drives the lower conveyor drive shaft 33 and the lower conveyor drive gear 35 on the same side to rotate synchronously. Since the lower conveyor drive gear 35 meshes with the lower conveyor transmission gear 34 on the same side, it drives multiple conveyor rollers 31 to rotate in the same direction and at the same speed, ensuring the smooth and continuous operation of the lower conveyor device 3 and providing reliable power for the normal operation of the reciprocating bottom washing machine.

[0071] The frame 1 has a lower conveying drive shaft 33 rotatably mounted on both its left and right sides, and lower conveying transmission gears 34 are fixedly fitted at both ends of the conveying rollers 31. This dual-side drive design ensures that the conveying rollers 31 receive uniform power input on both sides, avoiding problems such as uneven force distribution and unstable rotation caused by single-side drive. The uniform power distribution ensures the smooth rotation of the conveying rollers 31, thereby enabling the material to maintain a stable motion state during conveying and reducing material swaying and deviation.

[0072] The bottom of the frame 1 is also provided with a spray main pipe 5 and spray branch pipes 51. The spray main pipe 5 is installed in the front-to-back direction, and the spray branch pipes 51 are installed in the left-to-right direction. The spray main pipe 5 is interconnected with multiple spray branch pipes 51, and multiple spray branch pipes 51 are spaced apart between multiple conveying rollers 31.

[0073] The spray branch pipe 51 is provided with multiple spray holes with upward openings.

[0074] Multiple spray pipes 51 are spaced apart between multiple conveyor rollers 31, allowing the spraying range of the spray pipes 51 to cover most of the frame 1. Whether at the front, middle, or rear of the material frame 1, the spray pipes 51 can spray the material, avoiding the occurrence of cleaning dead corners and ensuring that all parts of the material are effectively cleaned. This more effectively removes dirt and impurities attached to the bottom of the material, improving the accuracy and efficiency of cleaning.

[0075] The main spray pipe 5 and multiple spray branch pipes 51 are perpendicular to each other and interconnected. This structure ensures that the water flowing in from the main spray pipe 5 can be evenly distributed to each spray branch pipe 51. The spray water volume obtained by each spray branch pipe 51 is relatively stable, which makes the intensity and range of the water flow sprayed from the spray hole more uniform, further improving the uniformity of cleaning.

[0076] The conveying roller 31 is fixedly fitted with multiple coaxially arranged wear-resistant rollers.

[0077] Wear-resistant rollers can greatly reduce the frictional resistance between the object and the conveying roller 31, allowing the object to move more smoothly during the conveying process. This reduces energy loss and slows down the conveying speed caused by excessive frictional resistance, improves the conveying efficiency of the reciprocating bottom washing machine, and helps to improve the overall production efficiency.

[0078] The wear-resistant rollers are installed on the conveyor roller 31 in a fixed manner. When the wear-resistant rollers are worn or damaged, they can be easily disassembled and replaced without replacing the entire conveyor roller 31, which reduces the difficulty and cost of maintenance and improves the maintainability of the equipment.

[0079] The outer ring of the cleaning roller 44 is provided with a wire brush.

[0080] Steel wire rollers possess high hardness and toughness, generating significant friction during the cleaning process. As the cleaning drum rotates, the steel wire rollers make full contact with the surface of the object being cleaned, penetrating deep into tiny crevices and depressions to effectively remove stubborn stains, oil, rust, and other impurities. This greatly improves the thoroughness and effectiveness of the cleaning, resulting in a cleaner surface.

[0081] The technical principles of this utility model have been described above with reference to specific embodiments. These descriptions are merely for explaining the principles of this utility model and should not be construed as limiting the scope of protection of this utility model in any way. Based on this explanation, those skilled in the art can readily conceive of other specific embodiments of this utility model without any inventive effort, and these embodiments will all fall within the scope of protection of this utility model.
