Abstract
Description
Technical Field
[0001] This utility model relates to a cardboard processing equipment, specifically a cardboard cutting and grooving machine. Background Technology
[0002] Some cardboard pieces need to have their four corners removed so that they can be folded into boxes or lids. Folding cardboard requires slotting the cardboard. For example... Figure 8 As shown, the existing paperboard process involves first using a paperboard cutting machine to partially cut lines on one side of the paperboard (e.g., ...). Figure 8 (As shown by the dotted lines), then a cardboard slotting machine cuts grooves along the cut lines on the other side of the cardboard. This causes the four corners of the cardboard to fall off because the cut lines and slotted lines coincide, resulting in cardboard that can be folded into boxes or lids. Existing cardboard cutting machines include a conveying mechanism and a cutting mechanism. The conveying mechanism includes conveyor rollers, and the cutting device includes a semi-circular blade, such as... Figure 9 As shown, the cardboard is conveyed by the conveyor rollers of the conveying device, and then the semi-circular blade 32 cooperates with the cutting roller 2 to cut a transverse slit B on the cardboard (the transverse slit B and the longitudinal slit A can be completed twice on the same cardboard cutting and slotting machine, simply by rotating the cardboard 90°; they can also be completed on two cardboard cutting and slotting machines; or a flat blade perpendicular to the semi-circular blade can be added to cut the longitudinal slit A on one cardboard cutting and slotting machine). However, the cutting motors 40 of existing cutting mechanisms are all installed horizontally (and the cutting motors 40 are relatively long in the horizontal direction), such as... Figure 7 As shown, the problem with this installation method is that when multi-channel cardboard cutting is required, multiple cutting motors need to be installed on the same crossbeam, such as... Figure 10 As shown, when dual-channel cardboard cutting is required, four cutting motors need to be installed on the same crossbeam. Since the cutting motors 30 are all installed horizontally, the interference between the two middle cutting motors 30 results in a relatively large minimum distance L between the two middle semi-circular blades 32. Since cardboard has different specifications, the cutting position is also different. If the minimum distance L between the two middle semi-circular blades 32 is smaller, the adjustment range of the cutting position is larger, which can better meet the processing requirements of different cardboard specifications and different cutting positions.

[0026] As Figure 1As shown, this cardboard cutting and slotting machine includes a paper feeding and conveying mechanism 1 and a slotting mechanism 4. The cardboard is fed forward through the paper feeding and conveying mechanism 1 (the paper feeding and conveying mechanism 1 includes a frame 10 and a conveying roller 11, which is the prior art) and enters the slotting mechanism 4 for cardboard slotting. The cardboard is cut while moving on the paper feeding and conveying mechanism 1.
[0027] The cardboard cutting is accomplished by the cooperation of the cutting roller 2 and the cutting mechanism 3, such as... Figure 2 As shown, the cutting roller 2 and the cutting mechanism 3 are mounted on the frame 10 and located on the conveying path of the paper feeding mechanism 1, with the cutting roller 2 located above the cutting mechanism 3.
[0028] like Figure 4 and Figure 5 As shown, the cutting mechanism 3 includes a base 34, a mounting plate 33, a semi-circular blade 32, a reducer 31, and a cutting motor 30 (servo motor). The mounting plate 33 is mounted on the base 34, the reducer 31 is mounted on the mounting plate 33, and the semi-circular blade 32 is mounted on a semi-circular blade mounting base 320. The output end of the reducer 31 is connected to the semi-circular blade mounting base 320, and the input end (one end of the output shaft) of the reducer 31 is connected to the output end of the cutting motor 30. The output end of the reducer 31 is perpendicular to the input end (the transmission structure of the reducer 31 can be made in this way). The output end of the cutting motor 30 is parallel to the blade surface of the semi-circular blade 32 (that is, the cutting motor 30 is mounted longitudinally). With this mounting method, the cutting motor 30 drives the reducer 31 to rotate the semi-circular blade mounting base 320 and the semi-circular blade 32. As the paperboard passes between the cutting roller 2 and the semi-circular blade 32, ... Figure 9 As shown, the semi-circular cutter 32 cuts lines on the cardboard. (As indicated...) Figure 3 As shown, in the case of a dual-channel four-cutting mechanism 3, since the cutting motor 30 is installed longitudinally, as... Figure 11 As shown, the distance L between the cutting motors 30 of the two middle cutting mechanisms 3 can be smaller, and the cutting motors 30 on the side can be closer to the frame 10. This makes the left and right adjustment range of the cutting mechanism 3 larger, thereby maximizing the processing needs of different specifications of cardboard.
[0029] In actual operation, the initial position of the cutting motor 30 may gradually shift after running for a period of time, thus affecting the cutting accuracy. To solve this problem, such as... Figure 4 and Figure 5As shown, the other end of the output shaft of the speed reducer 31 is connected with the induction disc 4 (the half-round knife 32 rotates by how many degrees, and the induction disc 4 also rotates by the corresponding angle), the induction disc 4 is provided with a long slot, and the induction disc 4 is provided with a slot photoelectric sensor 5 on one side. The slot photoelectric sensor 5 is controlled by the controller to control the cutting line motor 30. The equipment needs to be programmed to intervene after running for a period of time, and the program will automatically return to the original position once, that is, when the long slot of the induction disc 4 is aligned with the slot photoelectric sensor 5, the controller controls the cutting line motor 30 to complete the initial homing, thereby ensuring that the cutting line accuracy can be maintained for a long time.
[0030] In order to adjust the left and right positions of the cutting line mechanism 3, as shown in Figure 4 As shown, the base 34 is installed on the base sliding block 38, and as shown in Figure 3 A cross beam 12 extending left and right is installed on the rack 10, the cross beam 12 is provided with a guide rail 13, and the base sliding block 38 is slidingly arranged on the guide rail 13. By moving the position of the base sliding block 38 on the guide rail 13, the position of the cutting line mechanism 3 can be adjusted to meet the cutting line requirements of different specifications of paperboard.
[0031] In order to move and adjust the position of the cutting line mechanism 3, as shown in Figure 4 As shown, a rotatable adjusting gear 341 is installed on the base 34, and a rack parallel to the guide rail 13 is installed on the cross beam 12, and the adjusting gear 341 is engaged with the rack. When adjusting, only the adjusting gear 341 needs to be rotated to make the adjusting gear 341 move relative to the rack. Since the adjusting gear 341 is installed on the base 34 of the cutting line mechanism 3, the cutting line mechanism 3 can be adjusted. Of course, the adjusting gear 341 can also be connected with the adjusting motor for transmission, so as to realize automatic adjustment.
[0032] In order to adjust the up and down position of the half-round knife 32 to meet the requirements of different cutting line depths of paperboard, as shown in Figure 4 As shown in Figure 5 An adjusting seat 35 and a side plate 36 are installed on the base 34, and the adjusting seat 35 and the side plate 36 are fixedly connected, and the mounting plate 33 is movably installed between the adjusting seat 35 and the side plate 36, as shown in Figure 4As shown, the mounting plate 33 is provided with a rotating up-down adjusting screw 331 which is threadedly connected with the side plate 36, and the adjusting seat 35 is provided with a first long hole 351 extending upward and downward, and the first long hole 351 is provided with a first screw (not shown) which is threadedly connected with the mounting plate 33. When the up-down position of the half-round knife 32 needs to be adjusted, the up-down adjusting screw 331 is rotated, so that the mounting plate 33 can move up and down, and the half-round knife 32 is mounted on the mounting plate 33, so that the up-down position of the half-round knife 32 is adjusted, and when the up-down position is confirmed, the first screw is tightened to fix the mounting plate 33 on the adjusting seat 35, so that the up-down position of the half-round knife 32 is stable.
[0033] In order to guide the up-down movement of the adjusting seat 35, as shown, Figure 5 the adjusting seat 35 is connected with a first guide block 39 which is provided with a first guide groove extending upward and downward, and the mounting plate 33 is provided with a first guide protrusion 330 extending upward and downward, and the first guide protrusion 330 is arranged in the first guide groove. When the mounting plate 33 moves up and down, the first guide protrusion 330 moves up and down in the first guide groove, so that the up-down movement of the mounting plate 33 is more stable and accurate.
[0034] In order to adjust the front-rear position of the half-round knife 32 to adjust the cutting line position of the paperboard, as shown, Figure 5 the base 34 is provided with a second guide groove 343 extending forward and rearward, and the adjusting seat 35 is slidably arranged in the second guide groove 343, and the base 34 is provided with a rotating front-rear adjusting screw 342, as shown, Figure 4 the front-rear adjusting screw 342 is threadedly connected with the adjusting seat 35, and the adjusting seat 35 is provided with a second long hole 352 extending forward and rearward, and the second long hole 352 is provided with a second screw (not shown) which is threadedly connected with the base 34. When the front-rear position of the half-round knife 32 needs to be adjusted, the second screw is rotated, so that the adjusting seat 35 moves forward and rearward, and since the half-round knife 32 is mounted on the mounting plate 33 and the mounting plate 33 is fixed on the adjusting seat 35, the front-rear position of the half-round knife 32 is adjusted, and when the front-rear position is confirmed, the second screw is tightened to fix the adjusting seat 35 on the base 34, so that the front-rear position of the half-round knife 32 is stable.
[0035] In order to guide the front-rear movement of the adjusting seat 35, as shown, Figure 4As shown, the positioning block 37 is connected to the base 34 and located at one side of the side plate 36. The positioning block 37 is provided with a positioning protrusion 370 at the side close to the side plate 36. The side plate 36 is provided with a third guide slot extending in front and back direction. The positioning protrusion 370 is located in the third guide slot. When the adjusting seat 35 moves in front and back direction, the side plate 36 also moves in front and back direction together with the adjusting seat 35. Thus, the positioning protrusion 370 of the positioning block 37 moves in front and back direction in the third guide slot of the side plate 36. Thus, the movement of the adjusting seat 35 is more stable and accurate.
[0036] As mentioned above, the paperboard slitting and grooving machine further comprises a grooving mechanism 4. The grooving mechanism 4 comprises a grooving roller 42, a paper pressing belt 44 and a grooving cutter 41. The paper pressing belt 42 is wound around a guide roller 43 and acts on the grooving roller 42. The paper pressing belt 44 and the grooving roller 42 have a paperboard feeding port and a paperboard discharging port therebetween. After the paperboard is slit, it enters the grooving mechanism 4. Under the action of the paper pressing belt 44, the paperboard is attached to the grooving roller 42. With the rolling of the grooving roller 42 with the paperboard, the grooving cutter 41 at one side cuts grooves on the paperboard.
[0037] Finally, it is worth mentioning that, as Figure 4 With Figure 5 As shown, the paperboard is flexible. The paper passing supporting plate 6 is installed on the top of the mounting plate 33. The paper passing supporting plate 6 plays a supporting role between the conveying rollers 11 to prevent the paperboard from hanging and affecting the slitting depth.
