DETAILED DESCRIPTION

[0019] like Figure 1 As shown in the figure, this cardboard slitting, cutting and slotting integrated machine includes a cardboard slitting machine A, a cardboard cutting machine B and a cardboard slotting machine C. Fig.13 As shown, the cardboard slitting machine A is used to slit a large cardboard D into small cardboards F (4 to 24 pieces can be slit); Fig.14 As shown, the cardboard cutting machine B is used to cut the four corners of the small cardboard F; Fig.14 As shown, the cardboard slotting machine C is used to slot the small cardboard F, and the slotting line coincides with the cutting line, so that the four corners of the small cardboard F fall down, thereby completing the production of the finished cardboard product.

[0020] like Figure 1 and Figure 2 As shown, the cardboard slitting machine A includes a slitting and conveying device 1, a primary slitting device 2 and a secondary slitting device 4. The feeding direction of the secondary slitting device 4 is the same as the discharging direction (such as Figure 5 As shown, the cardboard enters from the right and exits from the left, so that the discharge port of the secondary slitting device 4 can be maintained at an appropriate height. The discharge port of the secondary slitting device 4 should be connected with the cardboard conveying device D, so that the cardboard conveying device D can also be maintained at an appropriate height. Since the cardboard conveying device D should be connected with the cardboard cutting machine B, the cardboard cutting machine B can be maintained at an appropriate height. Maintaining an appropriate height is not only convenient for observing the operation of the equipment, but also convenient for repair and maintenance); Fig.13As shown, the large cardboard D is transported by the slitting and conveying device 1 to the primary slitting device 2, which performs transverse slitting on the large cardboard D, and then enters the secondary slitting device 4, which performs longitudinal slitting on the middle cardboard E, thereby cutting it into small cardboards F.

[0021] like Figure 1 and Fig.10 As shown, the cardboard cutting machine B includes a cutting conveying device 70 and a cutting cutter 71 and a cutting roller 72 for cutting, wherein the cutting cutter 71 is located above the cutting roller 72; the cutting cutter 71 and the cutting roller 72 cooperate to cut the four corners of the small cardboard F. Since the cardboard conveying surface after the cardboard is separated is relatively low, in order to facilitate the replacement of the cutting cutter 71 (the cutting cutter 71 is a consumable part and needs to be frequently disassembled and ground), the cutting cutter 71 is arranged above the cutting roller 72 for easy disassembly; at the same time, since the small cardboard F is fed from the bottom of the primary slotting mechanism 9, the primary slotting cutter 91 of the primary slotting mechanism 9 slots the lower surface of the small cardboard F, and the cutting cutter 71 must be located above the cutting roller 72, and the cutting cutter 71 cuts the upper surface of the small cardboard F (cutting and slotting must be completed on the front and back sides of the cardboard respectively). Since the secant cutter 71 is above the secant pressure roller 72 , the secant cutter 71 will not be blocked by the secant pressure roller 72 , which makes it easy to adjust the position of the secant cutter 71 .

[0022] like Figure 1 and Fig. 9 As shown, the cardboard slotting machine C includes a slotting conveying mechanism 8, a primary slotting device 9 and a secondary slotting device 11. The small cardboard F after cutting the line is conveyed by the slotting conveying mechanism 8 and enters the primary slotting device 9, which slots the small cardboard F transversely, and then enters the secondary slotting device 11, which slots the small cardboard F longitudinally, thereby completing the production of the cardboard product.

[0023] In order to link the cardboard slitting machine A, cardboard cutting machine B and cardboard slotting machine C to achieve fully automated processing, such as Figure 1As shown, in the present invention, a cardboard conveying device D is connected to the discharge port of the secondary slitting device 4 (the cardboard conveying device D is a conventional conveying device, which can be a conveyor belt or a conveyor roller). The conveying direction of the cardboard conveying device D intersects with the discharge direction of the secondary slitting device 4, and the conveying surface of the cardboard conveying device D is lower than the discharge port of the secondary slitting device 4, so that the small cardboard F after slitting enters the cardboard conveying device D. Since the small cardboards F coming out of the secondary slitting device 4 may overlap, before entering the cardboard cutting machine B, it must be ensured that there is no gap between two adjacent small cardboards F. It must be in a separated state, so a cardboard separation mechanism 5 is provided at one end of the cardboard conveying device D, and the cutting cutter 71 of the cardboard cutting machine B is located in front of the cardboard separation mechanism D. After the small cardboard F is separated by the cardboard separation mechanism D, the cardboard cutting machine B cuts the small cardboard F, and the discharge end of the cardboard cutting machine B is connected with the slotting conveying mechanism 8 of the cardboard slotting machine C. After the small cardboard F is cut, it enters the slotting conveying mechanism 8 of the cardboard slotting machine C. Through the conveyance of the slotting conveying mechanism 8, the small cardboard F enters the primary slotting device 9 and the secondary slotting device 11 for slotting. Through this structure, the cardboard slitting machine A, the cardboard cutting machine B and the cardboard slotting machine C can be effectively linked, which significantly improves automation, reduces labor intensity and labor costs, and improves production efficiency. In addition, this cardboard cutting and grooving integrated machine has a very compact structure and a very reasonable layout. While completing the secondary cutting and secondary grooving, the cardboard conveying device D, the cardboard cutting machine B and the subsequent cardboard collecting device 6 can all be maintained at a suitable height, which is more conducive to future maintenance.

[0024] For the paperboard separating mechanism D, the present invention provides two embodiments.

[0025] Embodiment 1: This paperboard separation mechanism D can realize the storage and separation of small paperboards F. Figure 1 and Figure 7 As shown, the conveying surface of the cutting conveying device 70 is lower than the conveying surface of the cardboard conveying device 5, and the cardboard separation mechanism 5 includes a separation bin 50 and a separation front baffle 51, which are located above the conveying surface of the cutting conveying device 70, and there is a spacing between the separation front baffle 51 and the conveying surface of the cutting conveying device 70 that allows only one cardboard to pass through. Through this structure, the small cardboard F coming down from the cardboard conveying device 5 can fall onto the cutting conveying device 70 and be stacked in the separation bin 50. Since only one small cardboard F can pass between the separation front baffle 51 and the conveying surface of the cutting conveying device 70, the small cardboards F can be separated one by one and enter the subsequent cutting station. This cardboard separation mechanism D is suitable for the situation where the efficiency of the cardboard slitting machine A is greater than that of the cardboard cutting machine B, so it is difficult for the cardboard cutting machine B to digest the small cardboard F. The storage of materials through this cardboard separation mechanism D can appropriately alleviate this efficiency difference.

[0026] Embodiment 2: This paperboard separation mechanism D directly separates the small paperboards F. Figure 1 and Figure 8 As shown, the cardboard separation mechanism D includes a separation roller 52 and an upper pressing wheel 53, the upper pressing wheel 53 is located above the separation roller 52, and the small cardboard F passes between the upper pressing wheel 53 and the separation roller 52, and the linear speed of the separation roller 52 is greater than the conveying speed of the cardboard conveying device D. The cardboard separation mechanism D uses the linear speed of the separation roller 52 to be greater than the conveying speed of the cardboard conveying device D, and can quickly extract the small cardboard F and convey it to the cutting line conveying device 70, so that the small cardboard F can be separated. The cardboard separation mechanism D is suitable for the situation where the efficiency of the cardboard slitting machine A is equivalent to that of the cardboard cutting line machine B, and can be achieved by reducing the conveying speed of the cardboard slitting machine A.

[0027] At the same conveying speed, the efficiency of the cardboard slitting machine A is generally higher. One large cardboard D can produce four small cardboards F (or more) at a time, while the cardboard cutting machine B needs to cut the small cardboards F one by one. If one large cardboard D cuts out too many small cardboards F, it will be difficult for the cardboard cutting machine B to digest all the small cardboards F from the cardboard slitting machine A. Therefore, in order to ensure that the efficiency of the cardboard slitting machine A remains unchanged and to maximize production efficiency, the other end of the cardboard conveying device D is connected to the cardboard collecting device 6 or another cardboard cutting machine B for conveying. When the cardboard cutting machine B cannot digest all the small cardboards F from the cardboard slitting machine A, the small cardboards F from the cardboard slitting machine A can be transported to the cardboard collecting device 6 at the other end for stacking and storage through the reverse conveying of the cardboard conveying device D (such as Fig.14 As shown), or another cardboard cutting machine B and a cardboard slotting machine C are also configured at the other end of the cardboard conveying device D, so that the small cardboards F from the cardboard slitting machine A can be digested, thereby maximizing the processing efficiency.

[0028] like Figure 6 As shown, the cardboard collecting device 6 includes a stacking frame 60, a stacking platform 66 and a lifting power source. The stacking platform 66 is installed on the stacking frame 60 in a liftable manner, and the lifting power source can drive the stacking platform 66 to lift and lower. During operation, the small cardboards F from the cardboard conveying device D fall onto the stacking platform 66. As the small cardboards F are stacked, the lifting power source drives the stacking platform 66 to gradually descend, so that the small cardboards F can be stacked on the stacking platform 66. In addition, the stacking frame 60 is provided with a cardboard discharging window 68, and a cardboard pushing mechanism is provided opposite to the cardboard discharging window 68. The cardboard pushing mechanism includes a pushing plate 69 and a pushing power source for driving the cardboard pushing plate 69 to move forward and backward. When a certain amount of cardboard is stacked, the pushing power source drives the cardboard pushing plate 69 to move forward, so that the cardboard pushing plate 69 can push the cardboard out of the cardboard discharging window 68.

[0029] In order to arrange the cardboards, a positive cardboard stopper 61 is installed on the stacking frame 60, and the positive cardboard stopper 61 faces the direction in which the cardboards come in. A positive clapping board 62 is installed on the stacking frame 60, and the positive clapping board 62 is connected to a power source for driving the positive clapping board. The power source for driving the positive clapping board can drive the positive clapping board 62 to clap the cardboards in the direction of the positive cardboard stopper 61. Driven by the power source for driving the positive clapping board, the positive clapping board 62 claps the cardboards in the direction of the positive cardboard stopper 61, so that the cardboards are more neat in the positive direction.

[0030] In order to arrange the paperboards, a side paperboard stopper 63 is installed on the stacking frame 60, and the side paperboard stopper 63 is located on one side of the paper feeding direction. A side clapper 64 is installed on the stacking frame 60, and the side clapper 64 is connected to a power source for driving the side clapper. The power source for driving the side clapper can drive the side clapper 64 to clapper the paperboards toward the side paperboard stopper 63. Driven by the power source for driving the side clapper, the side clapper 64 claps the paperboards toward the side paperboard stopper 63, so that the paperboards are more neat in the lateral direction.

[0031] In order to stack the following paperboards while taking out the paperboards, a first paperboard supporting mechanism and a second paperboard supporting mechanism are installed on the stacking frame 60; the first paperboard supporting mechanism includes a first paperboard supporting rod 66 and a first paperboard supporting power source 660 that drives the first paperboard supporting rod 66 to move forward and backward; the second paperboard supporting mechanism includes a second paperboard supporting rod 67 and a second paperboard supporting power source 670 that drives the second paperboard supporting rod 67 to move forward and backward; the first paperboard supporting rod 66 and the second paperboard supporting rod 67 can move relative to each other to form a paper supporting surface. When the stacked paperboards are taken out, the first paperboard supporting rod 66 and the second paperboard supporting rod 67 can move relative to each other to form a paper supporting surface, and the following paperboards will temporarily fall on this paper supporting surface, and the stacked paperboards below can be taken out normally. When the stacked paperboards are taken out, the first paperboard supporting rod 66 and the second paperboard supporting rod 67 are relatively far away from each other, so that the paperboards fall on the stacking platform 66 and continue to be stacked.

[0032] like Figure 2 and Figure 3 As shown, the slitting conveyor 1 is connected with the feed port of the primary slitting device 2, the discharge port of the primary slitting device 2 is connected with the feed port of the secondary slitting device 4 through the transition conveyor 3, the discharge direction of the primary slitting device 2 is perpendicular to the conveying direction of the transition conveyor 3, and the feed direction of the secondary slitting device 4 is the same as the conveying direction of the transition conveyor 3. The large cardboard D enters the primary slitting device 2 through the slitting conveyor 1 for primary slitting, and the medium cardboard E that has been slid once enters the transition conveyor 3, and the transition conveyor 3 sends the medium cardboard E to the secondary slitting device 4, and the secondary slitting device 4 cuts the medium cardboard E into small cardboards F again.

[0033] like Figure 3As shown, the primary slitting device 2 includes a primary slitting knife 21, a primary slitting roller 22 and a primary slitting belt 24. The primary slitting belt 24 acts on the primary slitting roller 22 under the guidance of the guide roller, and the primary slitting knife 21 is located on one side of the primary slitting roller 22. The large cardboard D is attached to the primary slitting roller 22 under the action of the primary slitting belt 24. As the primary slitting roller 22 rotates, the large cardboard D moves, and the primary slitting knife 21 slits the large cardboard D. Figure 4 and Figure 5 As shown, the secondary slitting device 4 includes a secondary slitting knife 43 (a single slitting knife or two slitting knives can be used. Figure 5 As shown, if two slitting knives are used, one slitting knife 45 is below the cardboard, and the other secondary slitting knife 43 is above the cardboard, the two slitting knives are located in a line, and cooperate with each other to slit the cardboard), the secondary slitting roller 42 and the secondary paper pressing belt 44, the secondary paper pressing belt 44 acts on the secondary slitting roller 42 under the guidance of the guide roller, and the secondary slitting knife 43 is located on one side of the secondary slitting roller 42. Similarly, the middle cardboard E is attached to the secondary slitting roller 42 under the action of the secondary paper pressing belt 44. As the secondary slitting roller 42 rotates, the middle cardboard E moves, and the secondary slitting knife 43 slits the middle cardboard E into two small cardboards F. Of course, the feed port and the discharge port of the secondary slitting device 4 are both located at the top, and the feed direction is the same as the discharge direction, both in the same direction, such as Figure 5 As shown, the cardboard enters from the right and exits from the left, so that the discharge port of the secondary slitting device 4 can be maintained at an appropriate height. The discharge port of the secondary slitting device 4 must be connected with the cardboard conveying device D, so that the cardboard conveying device D can also be maintained at an appropriate height. Since the cardboard conveying device D must be connected with the cardboard cutting machine B, the cardboard cutting machine B can be maintained at an appropriate height. Maintaining an appropriate height is not only convenient for observing the operation of the equipment, but also convenient for repair and maintenance.

[0034] like Fig. 9 As shown, the discharging end of the slotting conveying device 8 is connected with the feeding end of the primary slotting device 9, the feeding end of the primary slotting device 9 is located at the bottom, the discharging end of the primary slotting device 9 is located at the top, the discharging end of the primary slotting device 9 is connected with the upper feeding device 10, the conveying direction of the upper feeding device 10 intersects with the discharging direction of the primary slotting device 9, the discharging end of the upper feeding device 10 is connected with the feeding end of the secondary slotting device 11, the feeding end of the secondary slotting device 11 is located at the upper end, and the discharging end of the secondary slotting device 11 is located at the lower end.

[0035] like Fig.12 As shown, the primary slotting device 9 includes a primary slotting knife 91, a primary slotting roller 90 and a primary slotting belt 92. The primary slotting belt 92 acts on the primary slotting roller 90 under the guidance of the guide roller, and the primary slotting knife 91 is located on one side of the primary slotting roller 90. The small cardboard F is attached to the primary slotting roller 90 under the action of the primary slotting belt 92. As the primary slotting roller 90 rotates, the small cardboard F moves, and the primary slotting knife 91 slots the small cardboard F. The secondary slotting device includes a secondary slotting knife, a secondary slotting roller and a secondary slotting belt. The secondary slotting belt acts on the secondary slotting roller under the guidance of the guide roller, and the secondary slotting knife is located on one side of the secondary slotting roller. The structure of the secondary slotting device is the same as that of the primary slotting device 9, except that the feeding and discharging directions are reversed up and down, which will not be repeated here.

One end of the blade of the longitudinal secant knife 711 is close to one end of the blade of the transverse secant knife 712. When the small cardboard F is between the secant pressure roller 72 and the semicircular knife (the linear speeds of the two are the same), the partial arc blade of the semicircular knife begins to roll into the cardboard, and is transported forward with the small cardboard F until the end of the blade of the semicircular knife leaves the cardboard, and a longitudinal secant line F1 is cut on the cardboard (as shown in FIG. 1 ).
