DETAILED DESCRIPTION

[0023] The utility model will be explained further in connection with the drawings:

[0024] The orientation terms involved in the paragraphs of detailed description are only for the convenience of the person skilled in the art to understand the technical solutions described in the application according to the visual orientation shown in the drawings. Except for explicit provisions and limitations, the terms "set", "install", "connect" and the like should be understood broadly, and the person skilled in the art can understand the specific meaning of the above terms in the utility model according to the specific circumstances.

[0025] As Figure 1 And Figure 2The illustrated multi-layer board processing plate deburring device comprises a main body 100, a conveying roller assembly 200, a roller brush assembly 300, a side brush assembly 400, a driving mechanism 500, the main body 100 is composed of a bearing platform 120 and an upper cover 110, a through cavity 101 is defined between the two, and a plurality of positioning and clamping assemblies 130 are installed at the opening of the through cavity 101; the conveying roller assembly 200 is provided in plurality and is installed at the position close to the opening of the through cavity 101; the roller brush assembly 300 is installed in the through cavity 101 and is adjacent to one of the conveying roller assemblies 200; the side brush assembly 400 is provided in plurality and is hingedly connected to the side of the roller brush assembly 300 away from the conveying roller in a symmetrical manner and is arranged adjacent to the roller brush assembly 300 and swings along the hinged point; the driving mechanism 500 is installed on the side of the bearing platform 120 away from the upper cover 110 and is connected with the conveying roller assembly 200, the roller brush assembly 300 and the side brush assembly 400; wherein the main body 100 of the conveying roller assembly 200 and the roller brush assembly 300 is the same structure, the difference is that the surface material of the roller is different. In this way, the multi-layer board to be processed enters the equipment through one end of the through cavity 101 and contacts the conveying roller assembly 200. The multi-layer board to be processed passes through the middle of the conveying roller assembly 200, and under the elastic action of the conveying roller assembly 200, it can automatically adapt to the thickness of the multi-layer board to be processed and clamp the multi-layer board to be processed. Not only can the clamping force of the rolling convey the multi-layer board to be processed at a constant speed into the equipment, but also can reduce the bouncing of the multi-layer board to be processed in the processing process through the clamping force, so that the multi-layer board can always remain stable, which not only improves the processing quality of the multi-layer board, but also improves the safety in the processing process. When the multi-layer board contacts the roller brush assembly 300, the roller brush assembly 300 and the conveying roller assembly 200 can also adapt to the thickness of the multi-layer board, and the continuously counterclockwise rotating roller brush can quickly and effectively clean the surface of the multi-layer board. At the same time, the roller brush assembly 300 cooperates with the conveying roller assembly 200 to fix the multi-layer board at multiple points, further improving the stability of the multi-layer board in the processing process. When the multi-layer board is driven by the conveying roller assembly 200, it continuously moves towards the other end of the through cavity 101, and after being processed by the roller brush assembly 300, the advancing end of the multi-layer board contacts the side brush assembly 400. Under the continuous movement of the multi-layer board, the side brush assembly 400 is pressed by the multi-layer board and deflects around the hinged point until the end of the side brush assembly 400 contacts the side wall of the multi-layer board and performs deburring and polishing work. After the side brush assembly 400 completes the polishing, it can be reset under its own elasticity and wait for the processing of the next multi-layer board. After being processed by the roller brush assembly 300 and the side brush assembly 400, the advancing end of the multi-layer board contacts the conveying roller assembly 200 at the other end of the through cavity 101 and is driven to send the multi-layer board out of the equipment.

[0026] As Figure 1As shown, the upper cover 110 is mounted with a plurality of dust suction pipes 111 on the side away from the support platform 120, and one end of the dust suction pipe 111 protrudes into the through cavity 101. In this way, the dust generated in the through cavity 101 can be timely extracted out of the equipment through the dust suction pipe 111, which not only optimizes the working environment, but also improves the working safety and avoids the risk of dust explosion

[0027] As shown in the drawings, Figure 3 As shown, the side brush assembly 400 includes a hinged support 410, a swing arm 420, a side roller brush 430, and a linkage assembly 440. The hinged support 410 includes a first support plate 411 and a second support plate 412, which are parallel to each other and connected to the inner wall of the through cavity 101. One end of the swing arm 420 is arranged between the first support plate 411 and the second support plate 412 and is hinged to both, and the other end is mounted with the side roller brush 430. The linkage assembly 440 is partially connected to the hinged support 410 and partially connected to the swing arm 420 and the side roller brush 430. In this way, the hinged support 410 and the swing arm 420 are hinged, and when the swing arm 420 is pressed by the end of the multi-layer board, the swing arm 420 can be offset around the hinge point until the side roller brush 430 abuts against the side wall of the multi-layer board and performs deburring work. With the cooperation of the hinged support 410 and the swing arm 420, the side brush assembly 400 has self-adaptive ability, and during the deburring process of multi-layer boards of different specifications, manual intervention is not required to adjust the distance of the side roller brush 430, effectively improving the self-adaptive processing capability of the equipment, and further improving the working efficiency and processing quality.

[0028] Optionally, a plurality of hinge springs are installed at the connection between the swing arm 420 and the hinged support 410. In this way, under the elastic action of the hinge springs, the swing arm 420 can be kept in close abutment with the side wall of the multi-layer board, ensuring the processing quality and uniformity of the deburring work. At the same time, after the swing arm 420 completes the deburring work and is separated from the side wall of the multi-layer board, it can be automatically reset for the next deburring work.

[0029] As shown in the drawings, Figure 3As shown, the linkage assembly 440 comprises a first linkage shaft 441, a second linkage shaft 442, a linkage belt 443, a transverse shaft 444, and a longitudinal shaft 445. The first linkage shaft 441 is located on the side of the first support plate 411 opposite the second support plate 412 and is rotatably connected to the first support plate 411. The first linkage shaft 441 is arranged at the end of the swing arm 420 where the side brush 430 is mounted, and the first linkage shaft 441 is fixedly connected to the side brush 430 through the swing arm 420. The linkage belt 443 is arranged between the first linkage shaft 441 and the second linkage shaft 442. The transverse shaft 444 is arranged adjacent to the first linkage shaft 441 and is engaged with the first linkage shaft 441. One end of the longitudinal shaft 445 is engaged with the transverse shaft 444, and the other end of the longitudinal shaft 445 passes through the first support plate 411, the second support plate 412, and the support platform 120 in sequence and is engaged with the driving mechanism 500. In this way, the first linkage shaft 441 is rotatably fixed above the first support plate 411 and is at the same level as the second linkage shaft 442 fixed above the side brush 430 at the other end of the swing arm 420, and the second linkage shaft 442 is fixedly connected to the side brush 430 through the swing arm 420, so that the two can rotate synchronously. At the same time, the second linkage shaft 442 can rotate synchronously with the first linkage shaft 441 through the connection of the linkage belt 443. Under the cooperation of the first linkage shaft 441, the transverse shaft 444, and the longitudinal shaft 445, the swing arm 420 can maintain the continuity of power during the offset process, so as to ensure that the side brush 430 can keep rotating continuously.

[0030] As Figure 4As shown, the brush roller assembly 300 comprises triangular supports 310, auxiliary spring rods 311, lifting plates 312, beam plates 313, main spring rods 314, upper brush rollers 320, lower brush rollers 330, the triangular supports 310 are provided in plurality, are hingedly connected to two ends of the upper brush rollers 320 respectively, and one end of each triangular support 310 is fixed with the auxiliary spring rods 311 in plurality; one end of the auxiliary spring rod 311 away from the triangular support 310 is fixed with the lifting plate 312 for connecting the upper cover 110; the beam plate 313 is fixed between the triangular supports 310, is adjacent to the upper brush roller 320, and one side of the beam plate 313 is provided with the main spring rods 314 in plurality; the lower brush roller 330 is embedded in the main body 100, is adjacent to the upper brush roller 320. In this way, the upper brush roller 320 is hung in the through cavity 101 through the cooperation of the triangular supports 310, the main spring rods 314 and the beam plate 313, so that it can be offset upward when subjected to pressure, and is automatically reset when losing pressure. And the upper brush roller 320 and the lower brush roller 330 are on the same straight line, and cooperate with each other, which not only can ensure the consistency and uniformity of the burr removal work, but also can ensure the clamping stability of the multi-layer board. In addition, in order to reduce the deformation of the upper brush roller 320 due to uneven force, the auxiliary spring rods 311 are installed above the triangular supports 310 as secondary support, and are fixedly connected with the inner wall of the upper cover 110 through the lifting plate 312, so as to offset the sinking force of the upper brush roller 320. At the same time, through the installed beam plate 313, the structural stability and the consistency of the offset of the upper brush roller 320 are further improved.

[0031] As shown in the figure, Figure 4 One end of the upper brush roller 320 protrudes out of the upper cover 110 and is provided with a linkage disc 321; one end of the lower brush roller 330 protrudes out of the bearing platform 120 and is provided with a multi-purpose connecting disc 331; the expansion wheel 332 is installed on one side of the linkage disc 321 and the multi-purpose connecting disc 331, and the linkage disc 321, the multi-purpose connecting disc 331 and the expansion wheel 332 are connected through the belt 333; wherein, the multi-purpose connecting disc 331 is connected with the linkage disc 321 and the expansion wheel 332 at the same time, and is also meshed and connected with the driving mechanism 500. In this way, in order to ensure that the linkage disc 321 and the multi-purpose connecting disc 331 can still maintain stable power output after being separated, the two are connected through the belt 333, and the tightness of the belt 333 can be automatically adjusted according to the offset of the linkage disc 321 through the expansion wheel 332 arranged therebetween, so that the belt 333 can always maintain close connection with the linkage disc 321 and the multi-purpose connecting disc 331.

[0032] Optionally, the expansion wheel 332 is provided with an expander 334 on one side. In this way, through the cooperation of the expansion wheel 332 and the expander 334, the connection stability of the belt 333 with the linkage disc 321 and the multi-purpose connecting disc 331 is ensured.

[0033] Optionally, the side wall of the multi-purpose connecting disc 331 is provided with a groove for connecting the belt 333, and the opening of the groove is provided with teeth on both sides for connecting the driving mechanism 500.

In this way, although the main body 100 of the conveying roller assembly 200 and the rolling brush assembly 300 are structurally the same, different wrapping materials can achieve different use effects. For example, the flexible material wrapped on the outside of the conveying roller assembly 200, including but not limited to rubber and silicone, can increase the friction with the multi-layer board by relying on its flexibility, and can maintain stable conveying capacity even when subjected to resistance from the rolling brush assembly 300 and the side brush assembly 400. The hard material wrapped on the rolling brush assembly 300, including but not limited to nylon and frosted material, and the hardness of the hard material is greater than that of wood, which can not only effectively remove burrs on the surface of the multi-layer board, but also can improve the service life of the upper rolling brush 320 and the lower rolling brush 330.
