Description

Technical Field

[0001] The utility model relates to cardboard processing equipment, in particular to a cardboard cutting and slotting integrated machine. Background Art

[0002] Cardboard slitting machine is a device that cuts large cardboard into small cardboards, such as Figure 11 As shown. Cardboard cutting machine is a device for cutting cardboard, such as Figure 12 As shown, the cardboard cutting machine can cut the four corners on one side of the cardboard ( Figure 12 F1 and F2 in the figure); and the cardboard slotting machine is a device for slotting cardboard tightly. The cardboard slotting machine generally includes a primary slotting device and a secondary slotting device. The primary slotting device and the secondary slotting device slot the other side of the cardboard in turn. Since the slotting is to open a V-shaped groove on the other side of the cardboard that coincides with the cut line ( Figure 12 (See F3 and F4 in the figure). This causes the four corners of the cardboard to fall off due to the overlap of the cut lines and the V-grooves. Existing cardboard slitting machines are all independent. Cardboard sheets from the slitting machines are manually transferred to a cardboard cutting machine for cutting. After cutting, they are transferred to a slotting machine for slotting, resulting in the finished cardboard with the corners removed.

[0025] like Figure 1 As shown in FIG, this cardboard cutting and slotting machine includes a cardboard cutting machine A, a cardboard cutting machine B and a cardboard slotting machine C. Figure 11 As shown, the cardboard slitting machine A is used to cut large cardboard D into small cardboard F; Figure 12 As shown, the cardboard cutting machine B is used to cut the four corners of the small cardboard F; Figure 12 As shown, the cardboard slotting machine C is used to slot the small cardboard F. 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.

[0026] like Figure 1 and Figure 2 As shown, the cardboard slitting machine A includes a slitting and conveying device 1 and a slitting device 4. The feeding direction of the slitting device 4 is the same as the discharging direction (as shown in FIG. Figure 5As shown, the cardboard enters from the right and exits from the left, so that the discharge port of the slitting device 4 can be maintained at an appropriate height. The discharge port of the slitting device 4 must be connected to 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 to 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 for repair and maintenance. Of course, a slitting device 4 with a feed port and a discharge port arranged above and below can also be used); as shown in FIG. Figure 11 As shown, a large cardboard D is conveyed by the slitting and conveying device 1 and enters the slitting device 4, which slits the large cardboard D into small cardboards F. Of course, the cardboard slitting machine A can also be a model with a primary slitting function (horizontal slitting) and a secondary slitting function (vertical slitting).

[0027] like Figure 1 and Figure 8 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. The cutting cutter 71 and the cutting roller 72 cooperate to cut the four corners of the small cardboard F.

[0028] like Figure 1 and Figure 9 As shown, the cardboard slotting machine C includes a slotting conveyor 8, a primary slotting device 9, and a secondary slotting device 11. The cut cardboard F is conveyed by the slotting conveyor 8 to the primary slotting device 9, which slots it transversely. The cardboard F then enters the secondary slotting device 11, which slots it longitudinally, completing the production of the finished cardboard.

[0029] 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, the present invention is connected with a cardboard conveying device D (the cardboard conveying device D is a conventional conveying device, which can be a conveyor belt or a conveyor roller) in front of the discharge port of the slitting device 4. The conveying direction of the cardboard conveying device D intersects with the discharge direction of the slitting device 4. The conveying surface of the cardboard conveying device D is lower than the discharge port of the slitting device 4. In this way, the small cardboards F that have been cut after entering the cardboard conveying device D. Since the small cardboards F that come out of the slitting device 4 may overlap, it must be ensured that there is a gap between the two adjacent small cardboards F before entering the cardboard cutting machine B. Therefore, a cardboard separation mechanism 5 is provided at one end of the cardboard conveyor device D. The cutting blade 71 of the cardboard cutting machine B is located in front of the cardboard separation mechanism 5. After the small cardboard F is separated by the cardboard separation mechanism 5, the cardboard cutting machine B cuts the small cardboard F. The discharge end of the cardboard cutting machine B is connected to the slotting conveyor device 8 of the cardboard slotting machine C. After the small cardboard F is cut, it enters the slotting conveyor device 8 of the cardboard slotting machine C. After being transported by the slotting conveyor device 8, the small cardboard F enters the primary slotting device 9 and the secondary slotting device 11 for slotting. This structure effectively links the cardboard slitting machine A, the cardboard cutting machine B, and the cardboard slotting machine C, significantly improving automation, reducing labor intensity and labor costs, and increasing production efficiency. In addition, this cardboard slitting, cutting, and slotting all-in-one machine has a very compact structure and a very reasonable layout. While completing cardboard slitting and secondary slotting, the cardboard conveyor device D, the cardboard cutting machine B, and the subsequent cardboard collection device 6 can all be maintained at a suitable height, which is more convenient for future maintenance and upkeep.

[0030] For the cardboard separating mechanism 5 , the present invention provides two embodiments.

[0031] Example 1: This cardboard separation mechanism 5 can realize the storage and separation of small cardboards F. Figure 1 and Figure 5 As shown, the conveying surface of the cutting conveyor 70 is lower than that of the cardboard conveyor D. The cardboard separating mechanism 5 includes a separation hopper 50 and a separation front baffle 51. These are located above the conveying surface of the cutting conveyor 70. There is a gap between the separation front baffle 51 and the conveying surface of the cutting conveyor 70, allowing only one cardboard to pass through. This structure allows small cardboards F from the cardboard conveyor D to fall onto the cutting conveyor 70 and be stacked within the separation hopper 50. Because only one small cardboard F can pass between the separation front baffle 51 and the conveying surface of the cutting conveyor 70, the small cardboards F can be separated one by one and sent to the subsequent cutting station. This cardboard separating mechanism 5 is suitable for situations where the efficiency of the cardboard slitting machine A is greater than that of the cardboard cutting machine B. Therefore, the cardboard cutting machine B has difficulty processing the small cardboards F. Using this cardboard separating mechanism 5 to store the cardboard can alleviate this efficiency difference.

[0032] Example 2: This paperboard separation mechanism 5 directly separates the small paperboards F. Figure 1 and Figure 6 As shown, this cardboard separation mechanism 5 includes a separation roller 52 and an upper pressure roller 53. The upper pressure roller 53 is located above the separation roller 52. The small cardboard F passes between the upper pressure roller 53 and the separation roller 52. The linear speed of the separation roller 52 is greater than the conveying speed of the cardboard conveyor D. This cardboard separation mechanism 5 utilizes the linear speed of the separation roller 52 to be greater than the conveying speed of the cardboard conveyor D, allowing the small cardboard F to be quickly extracted and conveyed to the cutting line conveyor 70, thereby also achieving separation of the small cardboard F. This cardboard separation mechanism 5 is suitable for situations where the efficiency of the cardboard slitting machine A is comparable to that of the cardboard cutting line machine B. This can be achieved by reducing the conveying speed of the cardboard slitting machine A.

[0033] At the same conveying speed, the efficiency of the cardboard slitting machine A is generally higher. One large cardboard D can produce two 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 too many small cardboards F are cut out from a large cardboard D, it will be difficult for the cardboard cutting machine B to digest all the small cardboards F produced by 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 (the cardboard collecting device 6 includes a collection platform) or another cardboard cutting machine B for conveying. When the cardboard cutting machine B cannot digest all the small cardboards F produced by the cardboard slitting machine A, the small cardboards F produced by 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 Figure 12 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 produced by the cardboard slitting machine A can be digested, thereby maximizing the processing efficiency.

[0034] like Figure 2 and Figure 3 As shown. The large cardboard D enters the cutting device 4 through the cutting and conveying device 1, and the cutting device 4 cuts the large cardboard D into small cardboards F again. Figure 4 As shown, the slitting device 4 includes a slitting knife 43 (a single slitting knife or two slitting knives can be used. Figure 5As shown, if two slitting knives are used, one slitting knife 45 is below the cardboard, and the other 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 slitting roller 42 and the pressing belt 44, the pressing belt 44 acts on the slitting roller 42 under the guidance of the guide roller, and the slitting knife 43 is located on one side of the slitting roller 42. The large cardboard D is attached to the slitting roller 42 under the action of the pressing belt 44. As the slitting roller 42 rotates, the large cardboard D moves, and the slitting knife 43 cuts the large cardboard D into two small cardboards F. Of course, the feed port and the discharge port of the slitting device 4 are both located at the top, and the feed direction is the same as the discharge direction, both facing in the same direction, as shown in FIG. Figure 4 As shown, the cardboard enters from the right and exits from the left, so that the discharge port of the slitting device 4 can be maintained at an appropriate height. The discharge port of the 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, this can also keep the cardboard cutting machine B 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.

[0035] like Figure 7 As shown, the discharge end of the slotting conveyor 8 is connected to the feed end of the primary slotting device 9, the feed end of the primary slotting device 9 is located at the bottom, and the discharge end of the primary slotting device 9 is located at the top. The discharge end of the primary slotting device 9 is connected to the upper feeding device 10, and the conveying direction of the upper feeding device 10 intersects with the discharge direction of the primary slotting device 9. The discharge end of the upper feeding device 10 is connected to the feed end of the secondary slotting device 11, and the feed end of the secondary slotting device 11 is located at the top, and the discharge end of the secondary slotting device 11 is located at the bottom. The small cardboard F with the cut lines is fed into the primary slotting device 9 through the slotting conveyor 8 for primary slotting (a transverse slot F3 is opened on the small cardboard F, as shown in FIG. Figure 12 As shown in FIG, the small cardboard F after the first slotting enters the upper feeding device 10, and the upper feeding device 10 feeds the small cardboard F to the secondary slotting device 11, and the secondary slotting device 11 performs a secondary slotting on the small cardboard F (a longitudinal slot F4 is opened on the small cardboard F, as shown in FIG. Figure 12 As shown), finally, the small cardboard F is slotted horizontally and vertically.

[0036] like Figure 10As shown, the primary slotting device 9 includes a primary slotting blade 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 a guide roller, and the primary slotting blade 91 is located on one side of the primary slotting roller 90. A 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 blade 91 slots the small cardboard F. The secondary slotting device includes a secondary slotting blade, a secondary slotting roller, and a secondary slotting belt. The secondary slotting belt acts on the secondary slotting roller under the guidance of a guide roller, and the secondary slotting blade is located on one side of the secondary slotting roller. The structure of the secondary slotting device is identical to that of the primary slotting device 9, except that the feed and discharge directions are reversed. This will not be described in detail here.

[0037] like Figure 9 As shown, the guillotine cutter 71 includes a transverse guillotine cutter 712 and a longitudinal guillotine cutter 711. Both the transverse guillotine cutter 712 and the longitudinal guillotine cutter 711 are mounted on a guillotine cutter holder 710. The guillotine cutter holder 710 is mounted on a guillotine rotating shaft 713. The guillotine rotating shaft 713 is connected to a guillotine power source that drives the guillotine rotating shaft 713. The longitudinal guillotine cutter 711 is a semicircular cutter, and the transverse guillotine cutter 712 is a flat cutter. One end of the blade of the longitudinal guillotine cutter 711 is close to one end of the blade of the transverse guillotine cutter 712. When the small cardboard F is between the guillotine pressure roller 72 and the semicircular cutter (the linear speeds of the two are the same), the partial arc blade of the semicircular cutter begins to press into the cardboard, and as the small cardboard F is transported forward, until the end of the blade of the semicircular cutter leaves the cardboard, a longitudinal guillotine line F1 is cut on the cardboard (as shown in FIG. 1 ). Figure 12 As shown), at the same time, the transverse cutting knife 712 is rolled into the cardboard, cutting a transverse cutting line F2 on the small cardboard F (as shown). Figure 12 As shown), an L-shaped cutting line can be cut on the small cardboard F.
