Description

Technical Field

[0001] This utility model relates to a cardboard processing equipment, specifically a cardboard slotting integrated machine for slotting cardboard. Background Technology

[0002] A bidirectional cardboard slotting machine is a machine that can slot cardboard both longitudinally and transversely. A typical bidirectional cardboard slotting machine includes two slotting mechanisms: a longitudinal slotting mechanism for longitudinal slotting and a transverse slotting mechanism for transverse slotting. A connecting conveyor mechanism connects the two slotting mechanisms. Cardboard from the longitudinal slotting mechanism first enters the connecting conveyor, which then feeds the cardboard into the transverse slotting mechanism. Both the longitudinal and transverse slotting mechanisms generally include slotting rollers, slotting knives, belts, and multiple tension rollers. Guided by the tension rollers, the belt acts on the slotting rollers, forming a cardboard inlet and an outlet. The cardboard enters through the inlet, and as the slotting rollers and belt rotate, the cardboard exits through the outlet. The slotting knives located on one side of the slotting rollers then slot the cardboard.

[0003] Some cardboard requires a large number of transverse and longitudinal slots. When there are too many slots and each pair of adjacent slots is very close together, the existing slotting blades cannot simultaneously handle the number of slots while also creating adjacent slots (adjacent slotting blades cannot get close enough). This prevents all types of slotting from being completed in a single feed, necessitating manual transfer from one slotting machine to another for the remaining work. If the number of slots on the cardboard is excessive, more transfers may be required to complete the task. Furthermore, since the cardboard is die-cut after printing, the reference edges on the cardboard can deform during multiple transfers, affecting the accuracy of subsequent slotting processes.

[0004] Ordinary two-way cardboard slotting machines are designed to a fixed size according to specifications. Therefore, only a limited number of slotting blades can be installed on the blade beam where the slotting blades are installed, which cannot meet the requirements for slotting more grooves. If the size of the two-way cardboard slotting machine is increased, the size of the parts must also be increased accordingly. This places higher demands on the processing accuracy of the parts and the rigidity of the whole machine, and makes debugging more troublesome. If the processing accuracy of the parts is not high, the cardboard slotting accuracy will not meet the requirements. Summary of the Invention

[0005] In view of the shortcomings of the existing technology, this utility model innovatively provides a multi-unit structure multi-linkage bidirectional cardboard slotting integrated machine.

[0006] This multi-linkage bidirectional cardboard slotting integrated machine includes a first cardboard slotting machine, which comprises a first feeding mechanism, a first longitudinal slotting mechanism, a first connecting conveying mechanism, a first transverse slotting mechanism, and a first discharging mechanism. The first feeding mechanism is connected to the feeding end of the first longitudinal slotting mechanism, and the discharging end of the first longitudinal slotting mechanism is connected to the first connecting conveying mechanism. The conveying direction of the first connecting conveying mechanism intersects with the discharging direction of the first longitudinal slotting mechanism. The first connecting conveying mechanism is connected to the feeding end of the first transverse slotting mechanism, and the discharging end of the first transverse slotting mechanism is connected to the first discharging mechanism. The machine is characterized in that the conveying direction of the first discharging mechanism intersects with the discharging direction of the first transverse slotting mechanism, and a second cardboard slotting machine is located in front of the discharging end of the first discharging mechanism. The second cardboard slotting machine comprises a second feeding mechanism and a second longitudinal slotting mechanism, which are connected to the first discharging mechanism and to the feeding end of the second longitudinal slotting mechanism.

[0007] The second cardboard slotting machine includes a second connecting conveying mechanism, a second transverse slotting mechanism, and a second discharging mechanism. The conveying direction of the second connecting conveying mechanism intersects with the discharging direction of the second longitudinal slotting mechanism. The second connecting conveying mechanism is connected to the feeding end of the second transverse slotting mechanism. The discharging end of the second transverse slotting mechanism is connected to the second discharging mechanism. The conveying direction of the second discharging mechanism intersects with the discharging direction of the second transverse slotting mechanism.

[0008] The second discharge mechanism is connected to the third cardboard slotting machine for conveying. The third cardboard slotting machine includes a third feeding mechanism, a third longitudinal slotting mechanism, a third connecting conveying mechanism, a third transverse slotting mechanism, and a third discharge mechanism.

[0009] The first feeding mechanism is provided with a first longitudinal paperboard correction mechanism, and the second feeding mechanism is provided with a second longitudinal paperboard correction mechanism. The first longitudinal paperboard correction mechanism is located on one side of the first feeding mechanism, and the second longitudinal paperboard correction mechanism is located on the other side of the second feeding mechanism.

[0010] The first discharge mechanism consists of several inclined rollers and can convey the cardboard to the side.

[0011] The feeding end of the first longitudinal grooving mechanism is located at the top, and the discharging end of the first longitudinal grooving mechanism is located at the bottom. The feeding end of the first transverse grooving mechanism is located at the bottom, and the discharging end of the first transverse grooving mechanism is located at the top. The feeding end of the second longitudinal grooving mechanism is located at the top, and the discharging end of the second longitudinal grooving mechanism is located at the bottom.

[0012] The first longitudinal grooving mechanism, the first transverse grooving mechanism, and the second longitudinal grooving mechanism all include a grooving roller, a grooving knife, a belt, and multiple tension rollers. The belt acts on the grooving roller under the guidance of the multiple tension rollers and forms a paperboard inlet and a paperboard outlet. The grooving knife is located on one side of the grooving roller.

[0013] A chip removal mechanism is installed on the first transverse grooving mechanism. The chip removal mechanism includes a chip removal pipe, an air suction pipe, and an exhaust fan. The exhaust fan is connected to the air suction pipe, and the air suction pipe is connected to the chip removal pipe. The chip removal pipe is used to remove the paper chips that fall off when the cardboard is grooved.

[0014] The multi-linkage bidirectional cardboard slotting machine provided by this utility model can not only meet the requirements for the number of slots, but also allow adjacent slots to be closer together, thus meeting different slotting spacing requirements. Attached Figure Description

[0018] like Figure 1 As shown, this multi-linkage bidirectional cardboard slotting integrated machine includes a first cardboard slotting machine 1. The first cardboard slotting machine 1 includes a first feeding mechanism 10 (including a conveyor belt or conveyor roller group), a first longitudinal slotting mechanism 11, a first connecting conveying mechanism 12 (including a conveyor belt or conveyor roller group), a first transverse slotting mechanism 13, and a first discharging mechanism 14 (including a conveyor belt or conveyor roller group). The first feeding mechanism 10 is used to convey the cardboard forward, the first longitudinal slotting mechanism 11 is used to perform longitudinal slotting on the cardboard, the first connecting conveying mechanism 12 is used to send the longitudinally slotted cardboard to the first transverse slotting mechanism 13, the first transverse slotting mechanism 13 is used to perform transverse slotting on the cardboard, and the first discharging mechanism 14 is used to send the bidirectional slotted cardboard to the next unit.

[0019] like Figure 1As shown, the first feeding mechanism 10 is connected to the feeding end of the first longitudinal slotting mechanism 11. The cardboard is fed into the first longitudinal slotting mechanism 11 through the first feeding mechanism 10, where longitudinal slotting is completed. The discharge end of the first longitudinal slotting mechanism 11 is connected to the first connecting conveyor 12. After longitudinal slotting is completed in the first longitudinal slotting mechanism 11, the cardboard enters the first connecting conveyor 12. The conveying direction of the first connecting conveyor 12 intersects with the discharge direction of the first longitudinal slotting mechanism 11, thus changing the conveying angle of the cardboard. The first connecting conveyor 12 is connected to the feeding end of the first transverse slotting mechanism 13, where the cardboard is conveyed to the first transverse slotting mechanism 13, where transverse slotting is completed (e.g., ...). Figure 3 (As shown); the discharge end of the first transverse grooving mechanism 13 is connected to the first discharge mechanism 14. The conveying direction of the first discharge mechanism 14 intersects with the discharge direction of the first transverse grooving mechanism 13, so the conveying angle of the cardboard is changed again and is the same as the conveying direction of the first feeding mechanism 10. A second cardboard slotting machine 2 is provided in front of the discharge end of the first discharge mechanism 14. The second cardboard slotting machine 2 includes a second feeding mechanism 20 and a second longitudinal grooving mechanism 21. The second feeding mechanism 20 is connected to the first discharge mechanism 14 (the second feeding mechanism 20 and the first discharge mechanism 14 can be an integral structure, that is, the same feeding mechanism, or they can be separate structures). The first discharge mechanism 14 delivers the cardboard that has completed one bidirectional grooving to the second feeding mechanism 20. The second feeding mechanism 20 is connected to the feeding end of the second longitudinal grooving mechanism 21, so the second feeding mechanism 20 delivers the cardboard to the second longitudinal grooving mechanism 21 for a second longitudinal grooving. This structure can significantly increase the number of slots on the paperboard, and on multiple units, the spacing between longitudinal slots on the paperboard can be brought infinitely close, thus greatly satisfying the slotting requirements of various types of paperboard.

[0020] like Figure 1 As shown, the second cardboard slotting machine 2 includes a second connecting conveyor mechanism 22, a second transverse slotting mechanism 23, and a second discharge mechanism 24. The conveying direction of the second connecting conveyor mechanism 22 intersects with the discharge direction of the second longitudinal slotting mechanism 21. The second connecting conveyor mechanism 22 is connected to the inlet end of the second transverse slotting mechanism 23, and the discharge end of the second transverse slotting mechanism 23 is connected to the second discharge mechanism 24. The conveying direction of the second discharge mechanism 24 intersects with the discharge direction of the second transverse slotting mechanism 23. Similar to the first cardboard slotting machine 1, the second transverse slotting mechanism 23 of the second cardboard slotting machine 2 can perform a second transverse slotting on the cardboard. This structure can significantly increase the number of slots on the cardboard, and on multiple units, the spacing between the transverse slots on the cardboard can be infinitely close, thereby greatly satisfying the slotting requirements of various types of cardboard.

[0021] To enable the third longitudinal and third transverse slotting, the second discharge mechanism 24 is connected to the third cardboard slotting machine 3. The third cardboard slotting machine 3 includes a third feeding mechanism 30, a third longitudinal slotting mechanism 31, a third connecting conveying mechanism 32, a third transverse slotting mechanism 33, and a third discharge mechanism 34. Similar to the first cardboard slotting machine 1 and the second cardboard slotting machine 2, the third cardboard slotting machine 3 performs the third longitudinal and third transverse slotting on the cardboard, which can further increase the number of slots.

[0022] In order to ensure that the cardboard always enters the slotting mechanism along a reference line on one side of the cardboard for slotting, such as Figure 1 As shown, a first longitudinal paperboard correction mechanism 15 is provided on the first feeding mechanism 10, and a second longitudinal paperboard correction mechanism 25 is provided on the second feeding mechanism 20. The first longitudinal paperboard correction mechanism 15 is located on one side of the first feeding mechanism 10, for example... Figure 1 The first longitudinal paperboard correction mechanism 15 is located to the right of the first feeding mechanism 10, so that the reference edge for the paperboard slotting is the right side of the paperboard. Figure 3 The thickened line on the side of the middle cardboard is the reference edge. The second longitudinal cardboard correction mechanism 25 is located on the other side of the second feeding mechanism 20, for example... Figure 1 The second longitudinal cardboard correction mechanism 25 is located to the left of the second feeding mechanism 20. Since the cardboard on the second feeding mechanism 20 has rotated 180° relative to the cardboard on the first feeding mechanism 10, the reference edge for cardboard slotting is still the right side of the cardboard. Because the cardboard enters the slotting mechanism with the right side of the cardboard as the reference, the longitudinal slotting mechanisms of all units can adjust the distance between the slotting cutter and the right side of the cardboard, making it easier to adjust the cardboard slotting position and improving slotting accuracy.

[0023] Similarly, a first transverse cardboard correction mechanism is provided on the first connecting conveyor mechanism 12, and a second transverse cardboard correction mechanism is provided on the second connecting conveyor mechanism 22. The first transverse cardboard correction mechanism is located on one side of the first connecting conveyor mechanism 12, and the second transverse cardboard correction mechanism is located on the other side of the second connecting conveyor mechanism 22. The purpose and function of the first transverse cardboard correction mechanism and the second transverse cardboard correction mechanism are the same as those of the first longitudinal cardboard correction mechanism 15 and the second longitudinal cardboard correction mechanism 25, and will not be elaborated further here.

[0024] It is worth mentioning that the first longitudinal paperboard correction mechanism 15, the first transverse paperboard correction mechanism, the second longitudinal paperboard correction mechanism 25, and the second transverse paperboard correction mechanism are all existing technologies. Their structure consists of a side plate and a row of inclined wheels. The row of inclined wheels transports the paperboard forward at an angle, and the paperboard moves forward against the side plate. In this way, the paperboard can enter the slotting mechanism for slotting with the side plate as a reference.

[0025] The first discharge mechanism 14 consists of several inclined rollers. Through these inclined rollers, the first discharge mechanism 14 can transport the paperboard to the side, so that the paperboard can approach the second longitudinal paperboard correction mechanism 25. The second longitudinal paperboard correction mechanism 25 can correct the position of the paperboard and send it into the second longitudinal slotting mechanism 21.

[0026] The feeding end of the first longitudinal slotting mechanism 11 is located at the top, and the discharging end of the first longitudinal slotting mechanism 11 is located at the bottom. The feeding end of the first transverse slotting mechanism 13 is located at the bottom, and the discharging end of the first transverse slotting mechanism 13 is located at the top. The feeding end of the second longitudinal slotting mechanism 21 is located at the top, and the discharging end of the second longitudinal slotting mechanism 21 is located at the bottom. This layout allows the cardboard to be discharged from a high position, so that after the cardboard is slotted, it can fall one by one to complete automatic stacking.

[0027] like Figure 2 As shown, the first longitudinal grooving mechanism 11, the first transverse grooving mechanism 13, the second longitudinal grooving mechanism 21, the second transverse grooving mechanism 22, the third longitudinal grooving mechanism 31, and the third transverse grooving mechanism 33 all include a grooving roller 60, a grooving knife 61, a belt 62, and multiple tension rollers 63 (including rollers that serve as guides and rollers that serve as tensioners). Under the guidance of the multiple tension rollers 63, the belt 62 acts on the grooving roller 60 and forms a paperboard inlet and a paperboard outlet. The paperboard enters from the paperboard inlet and is pressed onto the grooving roller 60 by the belt 62. As the grooving roller 60 and the belt 62 rotate, the paperboard moves, and the grooving knife 61 located on one side of the grooving roller 60 grooves the paperboard.

[0028] Finally, it is worth mentioning that when the cardboard is slotted by the first transverse slotting mechanism 13, the paper scraps will fly upwards because the cardboard moves from bottom to top. In order to collect the paper scraps that fall during the slotting process, a scrap suction mechanism is installed on the first transverse slotting mechanism 13. The scrap suction mechanism includes a scrap suction pipe 17, an air suction pipe 16, and an exhaust fan. The exhaust fan is connected to the air suction pipe 16, and the air suction pipe 16 is connected to the scrap suction pipe 17. The scrap suction pipe 17 is positioned at the slotting location of the cardboard. Through the exhaust fan, the scrap suction pipe 17 can collect the paper scraps that fall during the slotting process. The paper scraps enter the air suction pipe 16 from the scrap suction pipe 17, and the air suction pipe 16 then sends the paper scraps to the scrap collection box.
