DETAILED DESCRIPTION

[0027] The present invention is further described in detail below in conjunction with specific implementation methods.

[0028] See Figure 1The cardboard cutting device comprises a workbench 1, the workbench 1 has four supporting legs 11, and the supporting legs 11 are provided with universal wheels 12. Figure 2 The top surface of the workbench 1 is provided with a vertical bearing 13. The paperboard manufacturing equipment also includes a carrier plate 2 for carrying the paperboard raw material 102. The bottom wall of the carrier plate 2 is provided with a rotating shaft 21. The bottom end of the rotating shaft 21 is inserted downward into the bearing 13 and can rotate around the bearing 13. Figure 1 The top surface of the carrier plate 2 includes a fixing area 25 for placing the paperboard raw material 102 for fixing. The portion of the carrier plate 2 located in the fixing area 25 is provided with a first bolt 22 extending upward, and a first nut 23 is sleeved on the outer side of the first bolt 22. Figure 3 The top surface of the carrier plate 2 also includes a cutting area 24 for cutting the paperboard raw material 102. The portion of the carrier plate 2 located in the cutting area 24 is provided with a slide groove 26, and a slide rod 7 is installed in the slide groove 26. The outer side of the slide rod 7 is sleeved with two left and right parallel sliders 8, as shown in FIG. Figure 6 , 7 The slider 8 is provided with a slider through hole 82 which is passed through from left to right, and the slide rod 7 passes through the slider through hole 82. The slider 8 is provided with an avoidance groove 81 which is passed through from top to bottom. Figure 5 The outer side of the slide rod 7 is provided with two limit seats 6 for limiting the position of the slide block 8. Figure 8 The rear wall thereof is concave toward the front to form a U-shaped groove 61, the U-shaped groove 61 is through the left and right sides, and the slide bar 7 passes through the U-shaped groove 61, as shown in FIG. Fig.10 The upper groove wall 62 and the lower groove wall 63 of the U-shaped groove 61 are both provided with a second bolt through hole 64. Fig.10 The limit seat 6 includes a second bolt 65 and a second nut 66. The second bolt 65 passes through the second bolt through hole 64 and cooperates with the second nut 66 to clamp the slide bar 7 between the upper groove wall 62 and the lower groove wall 63, thereby fixing the limit seat 6 on the slide bar 7. The two limit seats 6 move along the part of the slide bar 7 located between the two sliders 8. Figure 5 , one of the limit seats 6 is arranged on the right side of the left slider 8 to limit the slider 8 from moving to the right, and the other limit seat 6 is arranged on the left side of the right slider 8 to limit the slider 8 from moving to the left. These two limit seats 6 are the first limit members. A limit spring 101 is arranged between the two sliders 8. The left end of the limit spring 101 is connected to the left slider 8 to limit the slider 8 from moving to the left, and the right end of the limit spring 101 is connected to the right slider 8 to limit the slider 8 from moving to the right. The limit spring 101 is specifically connected to the part of the slider 8 located above the slider through hole 82. The limit spring 101 is the second limit member. Using the limit spring 101 for limiting can reduce the number of limit seats 6 used, thereby reducing the workload of fixing the limit seats 6 and improving work efficiency.

[0029] See Figure 1The paperboard manufacturing device further includes a pressing plate 3 for fixing the paperboard raw material 102, and a first bolt through hole 31 corresponding to the position of the first bolt 22 is opened on the pressing plate 3. Fig.11 The top surface of the workbench 1 is provided with a dust collecting frame 100 surrounding the outer side of the carrier plate 2, and a dust collecting drawer box 9 which can be pulled out from the front side of the dust collecting frame 100 is installed in the dust collecting frame 100. The dust collecting drawer box 9 is located below the carrier plate 2, and a dust collecting through hole 93 is opened on the top surface 91 of the dust collecting drawer box 9. The above-mentioned slide groove 26 and the avoidance groove 81 are both connected from top to bottom, and the bottom notch of the avoidance groove 81 is downwardly connected to the top surface 91 of the dust collecting drawer box 9, so that the paper scraps and dust falling into the avoidance groove 81 can fall from the bottom notch of the avoidance groove 81 into the top surface 91 of the dust collecting drawer box 9, thereby preventing the paper scraps and dust from accumulating in the avoidance groove 81. A mounting frame 4 is provided at the rear portion of the top surface of the workbench 1, on which a telescopic rod 41 which can be extended up and down and a telescopic rod motor 42 for driving the telescopic rod 41 are provided, a cross bar 43 is provided at the bottom end of the telescopic rod 41, on which two L-shaped tool holders 5 are provided, each tool holder 5 is provided with a cutting knife 51 and a cutting knife motor 52 for driving the cutting knife 51, and the two cutting knives 51 are arranged side by side on the left and right, and are both located above the carrier plate 2 and the pressing plate 3.

[0030] The cardboard manufacturing equipment is operated as follows: the operator removes the first nut 23 from the first bolt 22, and operates the pressing plate 3 to move upward away from the first bolt 22; puts the cardboard raw material 102 on the carrier 2, operates the pressing plate 3 to align the first bolt through hole 31 of the pressing plate 3 with the first bolt 22 of the carrier 2, and places the pressing plate 3 downward on the cardboard raw material 102, and then screws the first nut 23 onto the first bolt 22 and tightens it until the first nut 23 fixes the pressing plate 3 and the cardboard raw material 102 between the first nut 23 and the carrier 2, a part of the cardboard raw material 102 is fixed between the pressing plate 3 and the carrier 2, and a part is located in the cutting area 24 of the carrier 2 and is exposed outside the pressing plate 3; according to the position where the cardboard raw material 102 needs to be cut, the cutting knife 51 is operated to move along the cross bar 43 The cutting knife 51 is moved until it is aligned with the cutting position of the cardboard material 102, and the slider 8 is operated to move along the slide bar 7 until the avoidance groove 81 of the slider 8 is aligned with the cutting knife 51. Since the cutting area 24 of the carrier plate 2 is located at the front of the workbench 1 and away from the cutting knife 51, the operator needs to operate the carrier plate 2 to rotate the rotating shaft 21 around the bearing 13 to move the cutting area 24 of the carrier plate 2 to below the cutting knife 51. After the carrier plate 2 is moved, the knife holder 5 is operated to move on the cross bar 43 so that the cutting knife 51 is aligned with the cutting position of the cardboard material 102, and then the cutting knife motor 52 drives the cutting knife 51 to rotate, and the telescopic rod motor 42 drives the telescopic rod 41 to make the telescopic rod 41 move downward with the cutting knife 51 to cut the cardboard material 102, leaving the following mark on the cardboard material 102: Fig.12The operator can fold the paperboard material 102 along the dotted line to fold the paperboard material 102 into a paper box with an open top. During the downward cutting process of the cutting knife 51, if the cutting knife 51 is accidentally moved too far downward, the excessively moved part of the cutting knife 51 will extend into the avoidance groove 81, and will not cut the groove wall of the avoidance groove 81 and the part of the carrier 2 outside the avoidance groove 81, so that the carrier 2 will not become consumables, thereby reducing costs.

[0031] The above is only an implementation method of the invention, and does not limit the scope of patent protection. Those skilled in the art can make non-substantial changes or substitutions based on the invention, which still fall within the scope of patent protection.
