Description

Technical Field

[0001] The utility model relates to the technical field of cutting equipment, in particular to a flat-press cutting equipment for cardboard manufacturing. Background Art

[0002] Flat pressing and cutting equipment is a special equipment mainly used to flatten and cut corrugated cardboard. It has functions such as flattening, compacting, shaping, and cutting.

[0003] A Chinese patent with authorization announcement number CN219445245U discloses a flat pressing and cutting device for cardboard manufacturing, comprising a base, a pressing roller portion arranged on one side of the base, and two groups of adjustment components arranged between the base and the pressing roller portion and rotatably connected to the pressing roller portion. Two threaded holes are symmetrically provided on the side walls on both sides of the base. The adjustment component comprises a long plate, a pressing plate arranged on one side of the long plate, and two bolts. Two through holes are symmetrically provided on the pressing plate, and the two through holes correspond to the two threaded holes respectively. The bolts pass through the through holes and engage in the threaded holes. By changing the length of the bolts screwed into the threaded holes, the distance between the pressing plate and the base member can be changed, and the force generated by the pressing plate on the long plate in the direction of the base changes. When the force is reduced, the pressure on the long plate is small, and the long plate can slide up and down to adjust the distance between the pressing roller portion and the base, thereby achieving the purpose that the pressing roller portion can flat press cardboards of different thicknesses.

[0004] In the above technical solution, when the distance between the pressure roller part and the base needs to be adjusted, four bolts need to be turned, which is rather cumbersome. In addition, when the distance between the pressure roller part and the base is shortened, the long plate moves downward. When the bottom of the long plate is lower than the bottom of the base, the entire device is in a tilted state, which makes it difficult for the device to operate normally.

[0005] Based on this, the utility model proposes a flat pressing and cutting device for cardboard manufacturing. Utility Model Content

[0006] In order to solve the above technical problems, the utility model proposes a flat pressing and cutting device for cardboard manufacturing, which can adjust the position of the pressing roller through a fixed component. When adjusting, it only needs to rotate the rotating rod, and the limiting component can be used to limit the moving direction of the cardboard to ensure that the moving direction of the cardboard will not change during the movement, thereby preventing it from falling off the base.

[0025] Further, such as Figure 1 and Figure 2 As shown, the cutting assembly 3 includes a support frame 31, a telescopic motor 32, a connecting plate 33 and a blade 34. The support frame 31 is fixedly connected to the base 1, and the cross-section of the support frame 31 is an inverted "U" shape. The telescopic motor 32 is fixed to the support frame 31 by bolts, and the connecting plate 33 is fixed to the output shaft of the telescopic motor 32 by bolts. The connecting plate 33 is slidably connected to the support frame 31, and the blade 34 is fixedly connected to the connecting plate 33. The length of the blade 34 is consistent with the length of the cutting groove 2.

[0026] Further, such as Figure 3 As shown, the fixing assembly 4 also includes a rotating column 45, a bevel gear 1 46 and a bevel gear 2 48. The two ends of the rotating column 45 are respectively rotatably connected to the two support boxes 41. The two bevel gears 1 46 are respectively rotatably connected in the two support boxes 41. The two bevel gears 1 46 and the two bevel gears 2 48 are symmetrical with the pressure roller 44 as the axis.
