Description

Technical Field

[0001] The invention belongs to the technical field of environmentally friendly paper box production, and in particular relates to an elastically clamped environmentally friendly paper box shearing device. Background Art

[0002] With the increasing awareness of environmental protection, the market demand for paper packaging materials is growing. In particular, environmentally friendly cartons, as an important form of packaging, have been widely used in the food, daily necessities and other industries. In the production process of environmentally friendly cartons, precise cutting technology is the key link to ensure the accuracy of the size, shape and appearance quality of the cartons. In the existing carton production process, cutting is carried out by cutting the paper into a fixed shape with a knife. When cutting, the cartons will go through automatic feeding, positioning, pressing and other links, striving to ensure the accuracy and consistency of each piece of paper during the cutting process. Especially in batch production, it is a common production method to stack multiple cartons and then cut them as a whole. This can improve production efficiency and reduce production time.

[0003] In the existing technology, most carton cutting devices use mechanical clamping or pressing devices to fix the position of the carton to ensure that the carton does not move too much during the cutting process. However, traditional clamping devices or pressing mechanisms may not be able to provide sufficiently uniform pressure when multiple carton boxes are stacked. Especially under the demand for efficient mass production, the pressure distribution is often uneven, which can easily lead to sliding or inaccurate positioning between the stacked carton boxes. The fixing device clamps or presses, however, these rigid devices may cause excessive pressure on the carton, resulting in damage to the carton, especially when the material of the environmentally friendly carton is thinner and more fragile. The carton may be damaged, deformed or the surface damaged due to excessive pressing force. For this reason, we design an elastically clamped environmentally friendly carton cutting device to provide another technical solution to the above technical problems. Summary of the Invention

[0026] Reference Figure 1-7 An elastically clamped environmentally friendly carton shearing device comprises a rectangular processing table 1, vertical support legs 2 are fixed at both ends of the bottom of the rectangular processing table 1, a movable rectangular support plate 4 is provided at one end of the top of the rectangular processing table 1, a liftable shearing knife 3 is provided on the top of the rectangular processing table 1, and a moving mechanism for moving the rectangular support plate 4 is provided at one end of the rectangular processing table 1;

[0027] The moving mechanism includes two L-shaped support columns 5, and L-shaped support columns 5 are fixed on both sides of the bottom of the rectangular processing table 1. A rectangular lifting block 7 is fixed to the output end of the L-shaped support column 5. One end of the rectangular lifting block 7 is rotatably connected to an oblique rotating column 9. The top of the oblique rotating column 9 is rotatably connected to a rectangular connecting block 10. A longitudinal sliding plate 11 is fixed to the top of the rectangular connecting block 10. A longitudinal mounting plate 14 is provided at the end of the longitudinal sliding plate 11 away from the rectangular support plate 4. An adjustment component for adjusting the position of the longitudinal mounting plate 14 is provided at one end of the longitudinal sliding plate 11;

[0028] The rectangular lifting block 7 and the oblique rotating column 9, as well as the oblique rotating column 9 and the rectangular connecting block 10, are rotatably connected via pins. The setting of the pins enables the rectangular lifting block 7 and the oblique rotating column 9, as well as the oblique rotating column 9 and the rectangular connecting block 10 to rotate better.

[0029] Both sides of the longitudinal sliding plate 11 are slidably connected to transverse polished rods 13, one end of which is fixed with a U-shaped support column 12, and the bottom of the U-shaped support column 12 is fixedly connected to the rectangular processing table 1, thereby enabling the longitudinal sliding plate 11 to slide transversely on the outside of the transverse polished rod 13;

[0030] Circular sliding holes adapted to the transverse polished rods 13 are provided on both sides of the interior of the longitudinal sliding plate 11. The transverse polished rods 13 are located inside the circular sliding holes and are slidably connected to the longitudinal sliding plate 11 through the circular sliding holes. The arrangement of the circular sliding holes enables the longitudinal sliding plate 11 to slide on the outside of the transverse polished rods 13, so that the transverse polished rods 13 can guide the movement trajectory of the longitudinal sliding plate 11.

[0031] Here, the operation of the first vertical hydraulic cylinder 6 enables the rectangular lifting block 7 to descend. The descent of the rectangular lifting block 7 enables the longitudinal sliding plate 11 to slide outside the transverse polished rod 13 through the oblique rotating column 9 and the rectangular connecting block 10, thereby enabling the longitudinal sliding plate 11 to move toward the outside of the carton.

[0032] The adjustment assembly includes a longitudinal threaded rod 15, the internal thread of the longitudinal mounting plate 14 is connected to the longitudinal threaded rod 15, one end of the longitudinal threaded rod 15 is fixed to a handwheel 16, the longitudinal threaded rod 15 is close to one end of the longitudinal sliding plate 11 and is rotatably connected to the longitudinal sliding plate 11 through a bearing, and longitudinal circular tubes 17 are fixed on both sides of the longitudinal mounting plate 14, the longitudinal circular tubes 17 pass through the interior of the longitudinal sliding plate 11 and are slidably connected to the longitudinal sliding plate 11, one end of the interior of the longitudinal circular tube 17 is slidably connected to a longitudinal sliding column 18, the longitudinal sliding column 18 is close to one end of the rectangular support plate 4 and is fixedly connected to the rectangular support plate 4;

[0033] A circular sliding block 19 is fixed to the end of the longitudinal sliding column 18 away from the rectangular support plate 4, and the circular sliding block 19 is located inside the longitudinal circular tube 17. A transverse rigid spring 20 is provided on the end of the circular sliding block 19 away from the longitudinal sliding column 18 and located inside the longitudinal circular tube 17, so that the movement of the longitudinal sliding column 18 enables the circular sliding block 19 to move inside the longitudinal circular tube 17;

[0034] A circular chute is provided inside the longitudinal circular tube 17. The circular sliding block 19 is located inside the circular chute and is slidably connected to the longitudinal circular tube 17 through the circular chute. The circular chute enables the circular sliding block 19 to slide inside the longitudinal circular tube 17. The sliding of the circular sliding block 19 causes the transverse rigid spring 20 to be deformed by force.

[0035] An anti-slip pad is provided at one end of the rectangular support plate 4 away from the longitudinal sliding column 18. The surface of the anti-slip pad is evenly distributed with anti-slip grooves. The anti-slip grooves are provided so that the rectangular support plate 4 can better fit the carton to be cut, preventing the carton from shifting during cutting.

[0036] Here, the hand wheel 16 is rotated, and the rotation of the hand wheel 16 enables the longitudinal threaded rod 15 to rotate, and the rotation of the longitudinal threaded rod 15 enables the longitudinal mounting plate 14 to move, and the movement of the longitudinal mounting plate 14 enables the rectangular support plate 4 to adjust its position to adapt to the position of the carton. When the rectangular support plate 4 is in contact with the carton, the transverse rigid spring 20 is provided, so that the rectangular support plate 4 can exert a certain force on the edge of the carton to prevent the carton from being displaced during shearing, and can prevent the rectangular support plate 4 from causing excessive pressure on the carton to cause damage to the carton, thereby improving the quality of shearing;

The shearing knife 3 is located inside the longitudinal support plate 22 and is slidably connected to the longitudinal support plate 22. A longitudinal fixing plate 21 is fixed to the top of the shearing knife 3. The longitudinal fixing plate 21 and the longitudinal support plate 22 are fixed by bolts. Through the operation of the second vertical hydraulic cylinder 8, the longitudinal support plate 22 can be vertically lifted and lowered, thereby enabling the height position of the shearing knife 3 to be adjusted, so that the shearing knife 3 can cut the carton;

[0038] Here, the operation of the second vertical hydraulic cylinder 8 enables the longitudinal support plate 22 to be lifted and lowered vertically, thereby enabling the shearing knife 3 to shear the carton. Through the setting of the bolts, the longitudinal fixing plate 21 can be disassembled from the longitudinal support plate 22 to facilitate the replacement of the shearing knife 3.

[0039] Working principle: The operation of the first vertical hydraulic cylinder 6 enables the rectangular lifting block 7 to descend. The descent of the rectangular lifting block 7 enables the longitudinal sliding plate 11 to slide outside the transverse polished rod 13 through the oblique rotating column 9 and the rectangular connecting block 10, thereby enabling the longitudinal sliding plate 11 to move toward the outside of the carton;

[0040] The hand wheel 16 is rotated. The rotation of the hand wheel 16 enables the longitudinal threaded rod 15 to rotate. The rotation of the longitudinal threaded rod 15 enables the longitudinal mounting plate 14 to move. The movement of the longitudinal mounting plate 14 enables the rectangular support plate 4 to adjust its position to adapt to the position of the carton. When the rectangular support plate 4 is in contact with the carton, the transverse rigid spring 20 is provided so that the rectangular support plate 4 can exert a certain force on the edge of the carton to prevent the carton from being displaced during shearing, and can prevent the rectangular support plate 4 from causing damage to the carton due to excessive pressure on the carton, thereby improving the quality of shearing.

[0041] The operation of the second vertical hydraulic cylinder 8 enables the longitudinal support plate 22 to be lifted and lowered vertically, thereby enabling the shearing knife 3 to shear the carton. Through the setting of the bolts, the longitudinal fixing plate 21 can be disassembled from the longitudinal support plate 22 to facilitate the replacement of the shearing knife 3.
