Description

Technical Field

[0001] The invention relates to the technical field of furniture surface cleaning, in particular to a machine for removing impurities from the surface of furniture before painting. Background Art

[0002] With the rapid development of the furniture manufacturing industry, the quality requirements for furniture surface treatment are also increasing. In the furniture production process, a large amount of wood chips and dust will inevitably be generated during the cutting, polishing and other processing steps. These fine particles are easy to adhere to the surface of the furniture. If they are not effectively removed, it will directly affect the subsequent painting process and the quality of the final product.

[0003] Traditional methods of removing impurities from furniture surfaces mainly include using tools such as air guns, rags or brushes for cleaning. However, these methods all have certain limitations. First, although using an air gun to blow can quickly remove some larger particles of wood chips, the dust it creates will cause fine dust in the air to fall back onto the surface of the furniture, causing secondary pollution. Secondly, during the wiping process, the rag can easily carry the adsorbed dust and wood chips to other parts, creating new pollution points. The brush also faces similar problems. Especially after the brush has been used for a period of time, it will accumulate a certain amount of impurities, further affecting the cleaning effect. The existence of these problems will not only increase the labor intensity of workers, but also incomplete cleaning will cause bulges to form after the paint solidifies, resulting in problems such as an uneven surface, which will seriously affect the aesthetics and durability of the furniture products. Summary of the Invention

[0004] In order to overcome the shortcomings of existing furniture surface impurity removal methods that cause impurities to return to the furniture surface, forming secondary pollution, and the impurity removal effect is poor, which not only increases the labor intensity of workers but also affects the subsequent painting effect, the purpose of the present invention is to provide a furniture surface impurity removal machine before painting.

[0008] As an improvement of the above solution, the moving mechanism includes: a screw motor installed on the guide frame; a moving block slidably connected to the guide frame, and the screw of the screw motor is threadedly connected to the moving block, and the bottom of the moving block is connected to the sliding plate.

[0009] As an improvement of the above-mentioned scheme, the retraction mechanism includes: a connecting spring, which is wound on the guide frame, and the two ends of the connecting spring are respectively connected to the sliding rod and the guide frame; a connecting seat, which is symmetrically connected to the side of the guide frame; a guide wheel, which is rotatably connected to the connecting seat; a pull rope, which is wound on the guide wheel, and one end of the pull rope is connected to the moving block, and the other end of the pull rope slides through the inside of the sliding rod; a limit block, which is connected to the other end of the pull rope, and the limit block contacts the side of the sliding rod; an elastic rope, which is symmetrically connected to the guide frame, and the end of the elastic rope is connected to the other end of the pull rope; a limit rod, which is symmetrically connected to the guide frame, and the sliding rod is slidably connected to the limit rod.

[0013] Beneficial effects: 1. The present invention can achieve efficient removal of impurities on the surface of furniture through the precise cooperation between the brushless motor, rotating drum, pressure roller and microfiber cloth. Specifically, the brushless motor drives the microfiber cloth to rotate, and the microfiber cloth is tightly attached to the surface of the furniture through the action of the rotating wheel, and its ultra-fine fiber characteristics are used to capture and absorb dust and particulate matter. This design can not only quickly remove larger particles of wood chips, but also effectively absorb fine dust, avoiding the secondary pollution problem caused by airflow or manual wiping in traditional methods. In addition, the vacuum cleaner is connected to the fixed cover through a connecting pipe, which can further enhance the cleaning effect under the action of negative pressure, ensuring that the furniture surface is clean and free of impurities.

[0014] 2. The present invention uses a fitting component and a rotating wheel to work together, allowing the microfiber cloth to flexibly adapt to various bumps and depressions on the furniture surface. When encountering uneven areas, the rotating wheel automatically adjusts its position to ensure that the microfiber cloth always adheres to the furniture surface. This design can greatly improve the comprehensiveness and effectiveness of cleaning. Even right-angle areas or other hard-to-reach areas on the furniture surface can be thoroughly cleaned. Especially when dealing with furniture with complex textures or decorative details, the system can ensure that every corner is cleaned, improving the quality of the final product.

[0015] 3. The present invention can adjust the turning radius of the right end of the microfiber cloth through the synergistic effect of the cleaning component and the bonding component. Specifically, when it is necessary to clean the right-angled area of the furniture surface, the screw motor drives the moving block to the right, driving the sliding plate and the roller to move closer to the inside of the microfiber cloth. At the same time, the pull rope and the connecting spring cause the rotating wheel to separate from the inside of the microfiber cloth, thereby reducing the turning radius of the right end of the microfiber cloth. This design allows the microfiber cloth to easily reach the right-angled areas or narrow parts of the furniture surface, completing the efficient cleaning of these hard-to-reach areas. Compared with the problem that traditional methods cannot effectively handle complex structures, this function can significantly improve the applicability and cleaning ability of the equipment, ensuring that every detail of the furniture surface can be thoroughly cleaned, providing a higher-quality surface foundation for the subsequent painting process. At the same time, this adjustment mechanism can also simplify the operating process, reduce manual intervention, and improve work efficiency.

[0016] 4. The present invention forms a multifunctional impurity removal mechanism through the cooperation of the first drive motor, the rotating rod, the rubber roller and the beating rod with the second drive motor and the brush rod. The beating rod knocks the part of the microfiber cloth on the outside with impurities to loosen it, and the brush rod further brushes and cleans it to ensure that the impurities are completely separated from the microfiber cloth. This combination not only improves the cleaning efficiency, but also ensures that the microfiber cloth always maintains a high adsorption capacity, ensuring the smooth progress of the subsequent painting process and improving the aesthetics and durability of the furniture products.

[0030] like Figure 5 and Figure 6As shown, the cleaning assembly includes a sliding plate 17, a roller 18, a moving mechanism and a retraction mechanism. The sliding plate 17 is slidably connected to the lower right side of the guide frame 11, and the roller 18 is rotatably connected to the right side of the sliding plate 17. The guide frame 11 is provided with a moving mechanism for driving the sliding plate 17 to move, so as to drive the roller 18 to move to contact the inner side of the microfiber cloth 6. The guide frame 11 is also provided with a retraction mechanism for controlling the retraction of the rotating wheel 7 to disengage the rotating wheel 7 from the inner side of the microfiber cloth 6; the moving mechanism includes a screw motor 19 and a moving block 20. The screw motor 19 is installed on the left side of the guide frame 11, and the moving block 20 is slidably connected to the lower part of the guide frame 11, and the screw of the screw motor 19 is threadedly connected to the moving block 20, and the bottom of the moving block 20 is fixedly connected to the sliding plate 17; the retraction mechanism includes a connecting spring 21, a connecting seat 22, a guide wheel 23, and a pull rope 24, limit block 2401, elastic rope 25 and limit rod 26, two connecting springs 21 are wound on the guide frame 11, and the two ends of the connecting spring 21 are respectively connected to the left side of the sliding rod 12 and the left part of the guide frame 11, the right side of the guide frame 11 is symmetrically connected to the connecting seat 22 front and back, the two connecting seats 22 are rotatably connected to the guide wheels 23, and the two guide wheels 23 are wound with a pull rope 24, the lower ends of the two pull ropes 24 are connected to the right side of the moving block 20, the upper ends of the two pull ropes 24 slide through the inside of the sliding rod 12, and the upper ends of the two pull ropes 24 are connected to the limit block 2401, the right side of the limit block 2401 contacts the left side of the sliding rod 12, and an elastic rope 25 is connected between the upper ends of the two pull ropes 24 and the upper left side of the guide frame 11, the right part of the guide frame 11 is symmetrically connected to the limit rod 26 front and back, and the sliding rod 12 is slidably connected to the two limit rods 26.

[0031] Initially, the connecting spring 21 and the elastic rope 25 are both in a stretched state; first, connect the connecting tube 10 to the vacuum cleaner, then hold the connecting tube 10 and place the right end of the microfiber cloth 6 against the surface of the furniture. The rotating wheel 7 and the swing frame 15 are squeezed by the furniture and swing upward relative to the sliding rod 12, causing the torsion spring 16 to deform. Under the elastic force of the torsion spring 16, a force is applied to the swing frame 15 and the rotating wheel 7 to swing downward, causing the rotating wheel 7 to press the right end of the microfiber cloth 6 tightly against the surface of the furniture; then start the vacuum cleaner, which can extract air from the fixed cover 9 through the connecting tube 10, forming a negative pressure state inside the fixed cover 9. At this time, an upward suction force is generated at the bottom of the fixed cover 9, and the outside air can enter the frame 8 through the air intake grille 2 and pass through the microfiber cloth 6 into the fixed cover 9, so that an upward airflow is formed between the frame 8 and the fixed cover 9, and then the brushless motor 3 is started, the brushless motor 3 can drive the microfiber cloth 6 to rotate, the rotating drum 4 and the pressure roller 5 are both used to assist the microfiber cloth 6 to rotate, the microfiber cloth 6 can wipe the surface of the furniture, and the ultrafine fibers on the microfiber cloth 6 can effectively capture and absorb impurities such as dust and particulate matter, so that the impurities on the surface of the furniture adhere to the outside of the microfiber cloth 6, and then the worker controls the right end of the microfiber cloth 6 to stick to the When the right end of the microfiber cloth 6 moves along the surface of the furniture, the surface of the furniture can be fully cleaned. When the part of the outer side of the microfiber cloth 6 with impurities is rotated between the square frame 8 and the fixed cover 9, the airflow will take away these impurities, thereby ensuring that the outer side of the microfiber cloth 6 is always in contact with the furniture surface with a clean part, ensuring a good impurity removal effect. When the right end of the microfiber cloth 6 moves along the surface of the furniture, if it encounters a raised part, the rotating wheel 7 corresponding to the raised part will be pushed upward, the microfiber cloth 6 will deform adaptively, and the rotating wheel 7 will drive the corresponding swing frame 15 to rotate upward, so that the corresponding torsion spring 16 continues to deform, and the rest The rotating wheel 7 will not be lifted up, so that the microfiber cloth 6 can remove impurities around the raised parts. When the microfiber cloth 6 passes over the raised parts, the corresponding torsion spring 16 will slightly return to its original shape, driving the corresponding swing frame 15 and the rotating wheel 7 to rotate downward, so that the microfiber cloth 6 returns to its original shape. Similarly, when encountering a concave part, the corresponding torsion spring 16 will drive the swing frame 15 and the rotating wheel 7 to rotate downward, so that the microfiber cloth 6 adaptively deforms and fits the concave part, ensuring the impurity removal effect. When the microfiber cloth 6 passes over the concave part, the swing frame 15 and the rotating wheel 7 will be pressed and rotated upward to restore, so that the microfiber cloth 6 returns to its original shape.When it is necessary to remove impurities from the right-angled part of the furniture surface, it is only necessary to control the screw motor 19 to drive the moving block 20 to move to the right. The moving block 20 can drive the sliding plate 17 and the roller 18 to move to the right, so that the roller 18 gradually approaches the inner side of the microfiber cloth 6, and the moving block 20 will relax the pull rope 24. At this time, the connecting spring 21 and the elastic rope 25 will return to their original state. The connecting spring 21 can drive the sliding rod 12 to move to the left. The sliding rod 12 can drive the swing frame 15 and the rotating wheel 7 to move to the left, so that the rotating wheel 7 gradually moves away from the inner side of the microfiber cloth 6. The elastic rope 25 can pull the upper end of the pull rope 24 to move to the left, and the pull rope 24 can drive the limit block 2401 to move to the left. When the connecting spring 21 is completely restored to its original state, the sliding rod 12 is The left side of the movable rod 12 will contact the left end of the limiting rod 26, and the limiting rod 26 will play a limiting role, so that the sliding rod 12, the swing frame 15 and the rotating wheel 7 will no longer move to the left, while the moving block 20, the sliding plate 17 and the roller 18 will continue to move to the right, and the elastic rope 25 will continue to restore its original state, driving the upper end of the pull rope 24 and the limiting block 2401 to move to the left, so that the limiting block 2401 is separated from the left side of the sliding rod 12. Through the action of the elastic rope 25, the part of the pull rope 24 that is relaxed by the moving block 20 can be completely retracted, ensuring that the pull rope 24 is always in a straight state and preventing the pull rope 24 from being separated from the guide wheel 23. At this time, the roller 18 will contact the inner side of the microfiber cloth 6 and can tighten the microfiber cloth 6 (such as; Figure 2 As shown), this can reduce the turning radius of the right end of the microfiber cloth 6, so that the right end of the microfiber cloth 6 can penetrate into the right-angle area of the furniture surface to complete the impurity removal work; when it is necessary to switch the roller 18 and the rotating wheel 7, it is only necessary to control the screw motor 19 to drive the moving block 20 to move to the left and reset. The moving block 20 can drive the sliding plate 17 and the roller 18 to move to the left, so that the roller 18 gradually moves away from the inner side of the microfiber cloth 6, and the moving block 20 can pull the limit block 2401 to the right and reset through the pull rope 24, so that the elastic rope 25 is stretched. When the limit block 2401 contacts the left side of the sliding rod 12, the limit block 2401 will push the sliding rod 12 to move to the right, and the connecting spring 21 is stretched, so that the left side of the sliding rod 12 is separated from the limit rod 26, and the sliding rod 12 can drive the swing frame 15 and the rotating wheel 7 to move to the right and reset, so that the rotating wheel 7 contacts the inner side of the microfiber cloth 6.

[0032] like Figure 7 and Figure 8 As shown, it also includes a first drive motor 27, a rotating rod 28, a rubber roller 29 and a beating rod 30. Two first drive motors 27 are installed on the left part of the rear mounting plate 1. The output shafts of the two first drive motors 27 are connected to the rotating rods 28. The two rotating rods 28 are both located inside the frame 8. The left and right sides of the two rotating rods 28 are connected to multiple rubber rollers 29. The multiple rubber rollers 29 on the same side are connected with a beating rod 30, and the beating rod 30 can contact the inner side of the microfiber cloth 6 as the rotating rod 28 rotates.

[0033] like Figure 9 As shown, it also includes a second drive motor 31 and a brush rod 32. The second drive motor 31 is symmetrically installed on the left and right sides of the rear side of the fixed cover 9. The brush rod 32 is symmetrically rotated inside the fixed cover 9. The rear ends of the rotating shafts of the two brush rods 32 are respectively connected to the output shafts of the two second drive motors 31, and the brush rods 32 are in contact with the outer side of the microfiber cloth 6.

[0034] When the device is in use, the rotating rod 28, rubber roller 29 and beating rod 30 can be driven to rotate by the first drive motor 27, and the brush rod 32 can be driven to rotate by the second drive motor 31; when the part of the outside of the microfiber cloth 6 with impurities attached rotates to between the square frame 8 and the fixed cover 9, the beating rod 30 can knock and slap the part of the outside of the microfiber cloth 6 with impurities attached to make the impurities fall off, and at the same time, the brush rod 32 can brush and clean the part of the outside of the microfiber cloth 6 with impurities attached to ensure that the impurities are completely separated from the microfiber cloth 6 so that the vacuum cleaner can suck them away and ensure the subsequent impurity removal effect; in the process of the beating rod 30 knocking and slapping the inner side of the microfiber cloth 6, since the microfiber cloth 6 is in a taut state, the pressure on the beating rod 30 can cause the rubber roller 29 to bend and deform, without squeezing and deforming the microfiber cloth 6.

[0035] like Figure 1 As shown, it also includes a support plate 33 and a roller 34. The support plate 33 is connected to the left side of the bottom of the two mounting plates 1, and the left and right sides of the lower parts of the two support plates 33 are rotatably connected to the rollers 34; the rollers 34 can support the device, so that the microfiber cloth 6 remains in an inclined state, and the worker does not need to use his hands to stabilize the position of the device all the time, saving time and effort. In addition, the rollers 34 can roll on the surface of the furniture to assist the microfiber cloth 6 in moving on the surface of the furniture.

[0036] The above description is only a specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any technician familiar with this technical field can easily think of changes or replacements within the technical scope disclosed by the present invention, which should be covered by the scope of protection of the present invention.
