[0027] To further illustrate the technical means and effects adopted by this utility model in order to achieve the intended utility model purpose, the following detailed description of the specific implementation methods, structure, features and effects of this utility model is provided in conjunction with the accompanying drawings and preferred embodiments.

[0028] Please see Figures 1-6 As shown, the purpose of this embodiment is to provide an automatic feeding and scraping machine for plywood, including a mounting base 1. A sliding groove a12 is provided on the upper surface of the mounting base 1 near one edge. A clamping block a15 is slidably installed in the sliding groove a12. A feeding groove 32 is provided on the upper surface of the mounting base 1 near the other edge. It also includes a mounting plate a2, which is symmetrically fixedly installed on both sides of the upper surface of the mounting base 1. A sliding groove b21 is provided through the side wall of the mounting plate a2. A mounting block 22 is slidably installed in the sliding groove b21. A scraping mechanism 4 is rotatably installed between the two mounting blocks 22. The scraping mechanism 4 scrapes the upper surface of the plywood 14 between the two mounting blocks 22. The height of the scraping mechanism 4 can be changed by sliding the mounting blocks 22 to scrape the plywood 14 of different thicknesses. An upper motor is fixedly installed on one side of the mounting block 22. The output shaft of the upper motor is fixedly connected to the scraping mechanism 4. The upper motor provides power for the rotation of the scraping mechanism 4. Several support legs 11 are fixedly installed on the lower surface of the mounting base 1 to support the mounting base 1.

[0029] The scraping mechanism 4 includes at least a mounting shaft 41. Several limiting blocks 42 are fixedly mounted in a circular array on the side wall of the mounting shaft 41. Several fixing screw holes 421 are opened on the upper surface of the limiting blocks 42. Several scraping wheels 44 are snapped onto the mounting shaft 41. Several limiting plates b43 are snapped onto both sides of the scraping wheels 44. The mounting shaft 41 drives the scraping wheels 44 to rotate through the limiting blocks 42 to scrape the edge of the sheet 14.

[0030] A lead screw a121 is rotatably mounted inside the sliding groove a12. One end of the lead screw a121 passes through the mounting base 1 and protrudes to the outside. A lead screw nut a151 is fixedly mounted on one side of the clamping block a15. The lead screw nut a151 is threaded onto the lead screw a121. The clamping block a15 is engaged with the lead screw nut a151 within the sliding groove a12, and the lead screw nut a151 has a T-shaped structure that is adapted to the sliding groove a12. Rotating the lead screw a121 moves the clamping block a15, thereby moving the plate 14.

[0031] The clamping block a15 has an L-shaped structure. A spring 153 is fixedly installed on the lower surface of the protruding part of the clamping block a15, and a clamping block b152 is fixedly installed on the other end of the spring 153. Figure 6As shown, the lower surface edge of the clamping block b152 is rounded. The spring 153 pushes the clamping block b152 to fix the plate 14, thereby improving the stability during scraping. The rounded corner at the lower surface edge of the clamping block b152 prevents damage to the plate 14 when the clamping block b152 fixes the plate 14.

[0032] Several feeding rollers 321 are rotatably installed inside the feeding trough 32. Several mounting plates b3 are symmetrically fixed on both sides of the upper surface of the mounting base 1. The mounting plates b3 are located on both sides of the feeding trough 32. A cylinder 31 is fixedly installed inside the mounting plate b3. A limit plate a311 is fixedly installed at one end of the piston rod of the cylinder 31. A bevel angle inclined towards the bottom of the feeding trough 32 is opened on one side of the limit plate a311. When the cylinder 31 pushes the limit plate a311, it passes between the scraping mechanisms 4 on both sides of the plate 14 of different sizes, preventing the plate 14 from tilting and affecting the scraping effect.

[0033] A lead screw b211 is rotatably installed inside the sliding groove b21. One end of the lead screw b211 passes through the mounting plate a2 and is exposed to the outside. A lead screw nut b221 is fixedly installed on one side of the mounting block 22. The mounting block 22 and the lead screw nut b221 form an I-shaped structure. The lead screw nut b221 is threaded onto the lead screw b211. Rotating the lead screw b211 drives the mounting block 22 to move up and down, thereby changing the height of the scraping mechanism 4 and scraping the edges of plates 14 of different thicknesses.

[0034] A processing groove 13 is provided through the middle of the upper surface of the mounting base 1. A scraping mechanism 4 is rotatably installed in the processing groove 13. The scraping mechanism 4 scrapes the edge of the lower surface of the plate 14 through the processing groove 13. A lower motor is fixedly installed on the side wall of the processing groove 13. The output shaft of the lower motor is fixedly connected to the scraping mechanism 4. The lower motor provides power for the rotation of the scraping mechanism 4.

[0035] The side wall of the limiting plate b43 has a through-hole 431, and the side wall of the limiting plate b43 has a plurality of slots 432 that connect to the through-hole 431. The arc-shaped side wall of the limiting plate b43 has a through-hole 433 that connects to the slots 432. A positioning bolt is installed in the internal thread of the positioning bolt hole 433. Tightening the positioning bolt in the positioning bolt hole 433 will install it into the fixing bolt hole 421 to fix the position of the limiting plate a311.

[0036] In practical use, when a scraping machine is required, the sheet metal 14 is placed from the feeding trough 32. The feeding roller 321 drives the sheet metal 14 between the two scraping mechanisms 4. The cylinder 31 pushes the limiting plate a311 to align the sheet metal 14 between the two scraping mechanisms 4, preventing the sheet metal 14 from tilting and affecting the scraping effect. The screw b211 is rotated to drive the mounting block 22 to slide, thereby changing the height of the scraping mechanism 4 and scraping the sheet metal 14 of different thicknesses. The scraping mechanism 4, which is rotatably installed in the processing groove 13, scrapes the lower edge of the sheet metal 14. The scraping wheel 44 scrapes the edge of the plate 14. Different sizes of scraping wheels 44 are replaced according to the thickness and width of the plate 14. The scraping wheel 44 is fixed by the limiting plates a311 on both sides of the scraping wheel 44. The positioning bolts in the positioning screw holes 433 are screwed into the fixing screw holes 421 to fix the position of the limiting plates a311. The clamping block b152 is pushed by the spring 153 to fix the plate 14 to improve the stability of the plate 14 during processing. The rotating screw a121 drives the plate 14 to move. At the same time, the plate 14 is scraped by the scraping mechanism 4.
