[0022] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.
[0023] Reference Figure 1-Figure 4 The top of the hydraulic cylinder 6 is fixed with a plurality of hydraulic cylinders 6, and one end of the hydraulic rods of the plurality of hydraulic cylinders 6 is fixed with a connecting plate 7 by bolts. The top of the upper support 4 is fixed with a plurality of connecting rods 12, and the top of the connecting rod 12 is slidably connected with the connecting plate 7 and the top of the support frame 3. The connecting plate 7 is driven by the hydraulic cylinder 6 to move, and then the upper support 4 is driven to move under the connection action of the connecting rod 12, thereby adjusting the distance between the upper support 4 and the lower support 2, and then adjusting the distance between the two feed pressing rollers 5 to adapt to the working environment. To flatten cardboards of different thicknesses, the outer wall of the connecting rod 12 between the upper support 4 and the connecting plate 7 is sleeved with a spring 14, and the flattening of the cardboard is buffered by the sliding connection between the connecting rod 12 and the connecting plate 7 and the top of the support frame 3 and the action of the spring 14, thereby avoiding damage to the cardboard. The outer wall of the connecting rod 12 above the connecting plate 7 is sleeved with a limit ring 13, and the outer wall of one end of the upper support 4 and the outer wall of one end of the lower support 2 are both rotatably connected with a hollow worm 9, which is engaged with the worm gear 8. The outer wall of one end of the lower support 2 is fixed with a motor 10 by bolts, and the output end of the motor 10 is fixed with a square rod 11 by bolts. The square rod 11 is slidably inserted with the two hollow worm gears 9, and the lower rod 11 is driven by the motor 10 to rotate, thereby driving the hollow worm gear 9 to rotate, and then driving the feed pressure roller 5 to rotate under the action of the engagement of the hollow worm gear 9 with the worm gear 8, thereby flattening the cardboard.
[0024] A plurality of auxiliary pressure rollers 15 are rotatably connected between the inner walls on both sides of the lower support 2 and the inner walls on both sides of the upper support 4. The other end between the inner walls on both sides of the lower support 2 and the other end between the inner walls on both sides of the upper support 4 are rotatably connected with a discharge pressure roller 16. The cardboard is conveyed to between the two discharge pressure rollers 16 through the auxiliary pressure rollers 15. One end between the feed pressure roller 5 and the discharge pressure roller 16 is connected to a belt 17 through a pulley drive. Under the transmission action of the belt 17, the discharge pressure roller 16 is driven to rotate, thereby further flattening the cardboard. The top of the base 1 A side seat 18 is fixed by bolts, and two limit plates 19 are slidably connected to the top of the side seat 18 by opening a slide groove. A two-way threaded rod 20 is rotatably inserted between the inner walls on both sides of the side seat 18, and the limit plate 19 is threadedly sleeved with the two-way threaded rod 20. Two guide rods 21 are welded between the inner walls on both sides of the side seat 18, and the limit plate 19 is slidably sleeved with the guide rod 21. Twisting the two-way threaded rod 20 drives the limit plate 19 to move along the guide rod 21, thereby adjusting the distance between the two limit plates 19 so as to flatten cardboards of different widths.
[0025] The working principle of this embodiment is as follows: when in use, first, the two-way threaded rod 20 is screwed to drive the limit plate 19 to move along the guide rod 21, thereby adjusting the distance between the two limit plates 19 to flatten cardboards of different widths. Then, the connecting plate 7 is moved under the drive of the hydraulic cylinder 6, and then the upper support 4 is moved under the connection of the connecting rod 12, thereby adjusting the distance between the upper support 4 and the lower support 2, and then adjusting the distance between the two feeding rollers 5 to suit the flattening of cardboards of different thicknesses. Then, the cardboard is placed on the side seat 18 and the cardboard is flattened. The cardboard is located between the two limit plates 19, and then the cardboard is pushed toward the feed roller 5. Then, the lower rod 11 is driven by the motor 10 to rotate, thereby driving the hollow worm 9 to rotate, and then the feed roller 5 is driven to rotate under the action of the engagement of the hollow worm 9 and the worm gear 8, thereby flattening the cardboard and conveying it forward. Then, under the action of the auxiliary pressure roller 15, it is conveyed to between the two discharge pressure rollers 16, and then, under the transmission action of the belt 17, the discharge pressure roller 16 is driven to rotate, thereby further flattening the cardboard and conveying it outward.
