[0021] Example 1

[0022] like Figure 1 , Figure 2 and Figure 7 As shown, a plywood pre-pressing device for cleaning surface debris conveniently comprises a pre-pressing part, the pre-pressing part comprises a pre-pressing mechanism 1 for pre-pressing the template blank, a fixed-length cutting mechanism 2 located downstream of the pre-pressing mechanism 1 for cutting the template blank to a fixed length, and a cleaning mechanism 4 located downstream of the fixed-length cutting mechanism 2 for cleaning the surface debris of the template blank, and a conveying device 3 for conveying the template blank is provided on the pre-pressing platform of the pre-pressing mechanism 1. The cleaning mechanism 4 comprises a cleaning brush 41 and a fixing plate 40, the longitudinal section of the fixing plate 40 is an L-shaped structure, the fixing seat 411 of the cleaning brush 41 is detachably connected to the transverse plate of the fixing plate 40 by bolts 412, and the fixing plate 40 is an L-shaped structure, which is convenient for positioning the fixing seat 411 of the cleaning brush 41 and fixing. The front end of the transverse plate of the fixed plate 40 is tilted downward so that the cleaning brush 41 can be tilted downward so that the lower end of the cleaning brush 41 contacts the surface of the template blank. The two ends of the frame of the fixed-length cutting mechanism 2 are fixed with mounting plates 42. The two ends of the fixed plate 40 are movably connected to the connecting assembly on the mounting plate 42 through the shaft 401 so that the cleaning end of the cleaning brush can move up and down. In this embodiment, the connecting assembly includes a strip hole 43 opened on the mounting plate 42 and arranged obliquely downward from one end close to the fixed-length cutting mechanism. The shafts 401 at the two ends of the fixed plate 40 are movably inserted into the strip hole 43.

[0023] When in use, after the pre-pressing mechanism 1 pre-presses the template blank, the fixed-length cutting mechanism 2 cuts the template blank into a fixed length, and the conveying device 3 on the pre-pressing mechanism 1 continues to convey the template blank after the fixed-length cut. Since the lower end of the cleaning brush 41 is in contact with the conveying plane, during the template blank conveying process, the cleaning brush 41 is pushed forward by the template blank, and the shaft rod 401 on the fixed plate 40 rotates in the strip hole 43. According to the thickness of the template blank, the cleaning brush 41 is rotated upward and moves upward along the strip hole 43 through the shaft rod 401, so that the cleaning brush 41 is always in contact with the surface of the template blank, which is suitable for cleaning the broken pieces of templates with different thicknesses. When the template blank passes through, it is affected by gravity and the cleaning mechanism 4 moves downward along the strip hole 43 to reset.

[0025] like Figure 3, Figure 4 and Figure 7 As shown, a plywood pre-pressing device for cleaning surface debris conveniently comprises a pre-pressing part, the pre-pressing part comprises a pre-pressing mechanism 1 for pre-pressing the template blank, a fixed-length cutting mechanism 2 located downstream of the pre-pressing mechanism 1 for cutting the template blank to a fixed length, and a cleaning mechanism 4 located downstream of the fixed-length cutting mechanism 2 for cleaning the surface debris of the template blank, a conveying device 3 for conveying the template blank is provided on the pre-pressing platform of the pre-pressing mechanism 1, and the cleaning mechanism 4 comprises a cleaning brush 41 and a fixing plate 40, the fixing plate 40 has a longitudinal direction The cross-section is L-shaped, and the fixing seat 411 of the cleaning brush 41 is detachably connected to the transverse plate of the fixing plate 40 by bolts 412. The front end of the transverse plate of the fixing plate 40 is tilted downward so that the cleaning brush 41 can be tilted downward so that the lower end of the cleaning brush 41 contacts the surface of the template blank. The two ends of the frame of the fixed-length cutting mechanism 2 are fixed with mounting plates 42, and the two ends of the fixing plate 40 are movably connected to the connecting components on the mounting plate 42 by the shaft rod 401, so that the cleaning end of the cleaning brush can move up and down. In this embodiment, the connecting assembly includes a connecting seat 44, a movable rod 45 and a spring 46. A vertically extending groove 421 is provided on the mounting plate 42. The connecting seat 44 is slidably provided at the lower end of the groove 421. A cross bar 422 is connected to the upper end of the groove 421. The shaft rods 401 at both ends of the fixed plate 40 are rotatably connected to the connecting seat 44. A movable rod 45 is fixed to the upper end of the connecting seat 44, and the upper end of the movable rod 45 movably passes through the cross bar 422 and is connected to a nut. A movable spring 46 is provided on the outer sleeve of the movable rod 45.

[0026] When in use, after the pre-pressing mechanism 1 pre-presses the template blank, the fixed-length cutting mechanism 2 cuts the template blank into a fixed length, and the conveying device 3 on the pre-pressing mechanism 1 continues to convey the template blank after the fixed-length cut.
