[0023] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this utility model, and should not be construed as limiting this utility model.

[0024] The plywood veneer surface treatment device of the present invention will now be described with reference to the accompanying drawings.

[0025] like Figures 1-5 As shown, the plywood veneer surface treatment device provided in this embodiment of the utility model includes a treatment box 1, a waste transfer mechanism 2 and a surface cleaning mechanism 4. The waste transfer mechanism 2 is arranged on both sides of the treatment box 1 and includes a negative pressure fan 21 and a blower 22 respectively arranged on both sides of the treatment box 1.

[0026] The surface cleaning mechanism 4 is located inside the processing box 1 and includes a pressing roller 41 and a brush roller 42. The pressing roller 41 has two parts, one above the other, and the brush roller 42 is rotatably located inside the pressing roller 41.

[0027] Specifically, during the cleaning process of the veneer 5, the veneer 5 is fed between two upper and lower pressing rollers 41. As the pressing rollers 41 rotate, they transport the veneer 5 while simultaneously clamping it stably. During clamping, the brush roller 42 on the inner side of the pressing roller 41 creates a speed difference relative to the pressing roller 41. The brush roller 42 cleans the veneer 5 clamped by the pressing roller 41, reducing deformation and damage to the veneer 5 during cleaning and resulting in a more thorough cleaning. After cleaning, the waste generated by the veneer 5 is blown away from the surface of the veneer 5 by the blower 22, and then collected by the negative pressure fan 21, making the surface of the veneer 5 even cleaner.

[0028] In one embodiment of this utility model, such as Figures 3-5 As shown, the interior of the processing box 1 is equipped with a cleaning drive motor 45, which drives the pressing roller 41 and the brush roller 42 to rotate. The pressing roller 41 is a cylindrical structure with a hollowed-out surface, and the radius of the brush roller 42 is larger than the radius of the pressing roller 41.

[0029] A differential drive assembly 47 is provided between the cleaning drive motor 45 and the pressing roller 41 and the brush roller 42, including a planetary gear unit, a pressing roller rotor 43 and a brush roller shaft 44. The brush roller shaft 44 is located at the center of the brush roller 42. The pressing roller rotor 43 is rotatably mounted on the brush roller shaft 44 through a bearing 477. The pressing roller rotor 43 is fixedly connected to the pressing roller 41.

[0030] The planetary gear unit includes an external gear ring 471, planetary gears 475, and a sun gear 476. The external gear ring 471 is connected to the press roller rotator 43 via a coupling 472. The planetary gears 475 are located inside the external gear ring 471, and the sun gear 476 is located inside the planetary gears 475. The two ends of the sun gear 476 are connected to the output shaft of the cleaning drive motor 45 and the brush roller shaft 44, respectively. A planetary gear carrier 473 is provided on the planetary gears 475, and the planetary gear carrier 473 is fixedly connected to the housing of the cleaning drive motor 45 via a gear carrier fixing rod 474.

[0031] Specifically, during the rotation of the pressing roller 41 and the brush roller 42, the cleaning drive motor 45 drives the sun gear 476 and the brush roller shaft 44 to rotate synchronously. At the same time, the rotation of the sun gear 476 meshes with the planet gear 475, driving the planet gear 475 to rotate. The planet gear 475 meshes with the outer gear ring 471, driving the outer gear ring 471 to rotate. Since the circumference of the outer gear ring 471 is greater than that of the sun gear 476, the rotation speed of the outer gear ring 471 is slower than that of the sun gear 476. Consequently, the rotation speed of the brush roller shaft 44 is greater than that of the pressing roller pivot 43, and thus the rotation speed of the brush roller 42 is greater than that of the pressing roller 41. Thus, a speed difference is formed between the brush roller 42 and the pressing roller 41.

[0032] Since the pressing roller 41 is a cylindrical structure with a hollowed-out surface, and the radius of the brush roller 42 is larger than the radius of the pressing roller 41, the brush tip on the high-speed rotating brush roller 42 can pass through the pressing roller 41 and clean the single board 5 at the bottom of the pressing roller 41 through the speed difference.

[0033] In one embodiment of this utility model, such as Figures 3-5 As shown, there are two cleaning drive motors 45, one above the other. Each of the two cleaning drive motors 45 is connected to a planetary gear unit to drive the two pressing rollers 41 to rotate synchronously in opposite directions and continuously transport the single board 5 to the right. A spacing adjustment arm 46 is also provided between the two cleaning drive motors 45 to adjust the clamping spacing between the two pressing rollers 41 according to the different thicknesses of the single board 5.

[0034] In one embodiment of this utility model, such as Figures 3-5 As shown, the air inlet of the negative pressure fan 21 is provided with an air inlet 212, and the air outlet of the blower 22 is provided with an air outlet 221. Both the air inlet 212 and the air outlet 221 are provided with two parts, one above the other, and the air inlet 212 and the air outlet 221 are on the same horizontal line. The air outlet of the negative pressure fan 21 is provided with a waste outlet 211.

[0035] Specifically, the high-speed airflow blown out by the outlet 221 travels horizontally to the inlet 212 and is absorbed. During this process, the waste debris swept off the surface of the panel 5 is mixed with the airflow and transferred. Since both the inlet 212 and the outlet 221 are provided with two parts, one at the top and one at the bottom, both sides of the panel 5 can be cleaned simultaneously. Finally, the airflow containing waste debris drawn back by the negative pressure fan 21 is discharged through the waste outlet 211.

[0036] In one embodiment of this utility model, such as Figures 1-3 As shown, the processing chamber 1 is provided with an inlet 11 and an outlet 12. A feeding assembly 3 is provided inside both the inlet 11 and the outlet 12. The feeding assembly 3 includes a feeding roller 32. A feeding drive motor 31 for driving the feeding roller 32 is provided on the outside of the processing chamber 1. A sedimentation hopper door 15 is provided at the bottom of the processing chamber 1. A base 13 is provided on the lower surface of the processing chamber 1, and a mounting bracket 14 is provided on the base 13.

[0037] Specifically, the inlet 11 and outlet 12 are used for the single board 5 to enter and exit the processing box 1. During the process of the single board 5 entering and exiting the processing box 1, the single board 5 is continuously transported by the feeding roller 32, making the transmission process of the single board 5 more stable. The waste residue remaining in the processing box 1 is deposited at the bottom of the processing box 1, and the deposited waste residue can be removed later by opening the deposit hopper door 15. In addition, the bottom of the processing box 1 is mounted on the base 13 by the bracket 14, which facilitates the upward opening of the processing box 1 to maintain its internal structure.

[0038] To clearly illustrate the above embodiments, refer to Figures 1-5 The working principle of the plywood veneer surface treatment device of this utility model is as follows: In the process of cleaning the surface of veneer 5, veneer 5 is first put into the feed port 11. The veneer 5 is continuously transported by the feeding roller 32 and then passed out from the discharge port 12 by the two pressing rollers 41.

[0039] When the single board 5 enters between the upper and lower pressing rollers 41, the cleaning drive motor 45 drives the sun gear 476 and the brush roller shaft 44 to rotate synchronously. At the same time, the sun gear 476 drives the outer gear ring 471 to rotate. Since the circumference of the outer gear ring 471 is greater than the circumference of the sun gear 476, the rotation speed of the outer gear ring 471 is slower than that of the sun gear 476. Consequently, the rotation speed of the brush roller 42 is greater than that of the pressing roller 41, and a speed difference is formed between the brush roller 42 and the pressing roller 41.

[0040] During the rotation of the pressing roller 41, the single-layer board 5 is transported and stably clamped. Since the pressing roller 41 has a hollowed-out cylindrical structure, and the radius of the brush roller 42 is larger than that of the pressing roller 41, the brush tip on the high-speed rotating brush roller 42 can penetrate the pressing roller 41 and clean the single-layer board 5 at the bottom of the pressing roller 41. Furthermore, the brush roller 42 cleans the single-layer board 5 clamped by the pressing roller 41, reducing deformation and damage to the single-layer board 5 during cleaning, resulting in a more thorough cleaning.

[0041] After cleaning, the high-speed airflow blown from the outlet 221 travels horizontally to the inlet 212 and is absorbed. During this process, the debris swept from the surface of the panel 5 is mixed with the airflow and transferred. Since both the inlet 212 and the outlet 221 have two parts, one at the top and one at the bottom, both sides of the panel 5 can be cleaned simultaneously. Finally, the airflow containing debris drawn back by the negative pressure fan 21 is discharged through the waste outlet 211, making the surface of the panel 5 even cleaner.

[0042] Although embodiments of the present invention have been shown and described above, it is understood that the above embodiments are exemplary and should not be construed as limiting the present invention. Those skilled in the art can make changes, modifications, substitutions and variations to the above embodiments within the scope of the present invention.
