Description

Technical Field

[0001] The invention relates to the technical field of corrugated paper box processing equipment, and in particular to a vertical creasing and slotting machine for a digital printing machine. Background Art

[0002] With the gradual advancement of science and technology, the technology of digital printing machines has developed more and more rapidly. The emergence of digital printing machines has improved the printing quality of cartons and can print richer patterns. It has been widely used in the high-end printing and packaging industry. Compared with traditional printing equipment, the cost of digital printing is mainly reflected in the nozzles. In other words, the more nozzles are used, the higher the cost. The larger the width of the printed material, the more nozzles are used, which leads to higher cost.

[0003] At present, traditional corrugated box processing equipment all adopts horizontal paper feeding, that is, slotting and die-cutting machines all feed paper horizontally, so as to perform slotting, die-cutting and other processing on the horizontally conveyed cardboard. Specifically, for the current slotting machine, it includes two shafts arranged side by side and connected by transmission, one of which is equipped with four knife seats, and the knife seats can be slidably connected to the shaft along the axial direction, so that the spacing between the knife seats can be adjusted to adapt to cardboards of different widths. The knife seats are equipped with arc knives, so that the cardboard is slotted when the two shafts perform a circular pressing action. At this time, a slot is opened on the cardboard in the same direction as the conveying direction. Therefore, when a digital printing machine is used for printing, since the slotting and die-cutting machines all feed and process paper horizontally, the cardboard input into the digital printing machine is placed horizontally. Therefore, the digital printing machine needs to use more nozzles to print the horizontally conveyed cardboard, which leads to an increase in printing costs.

[0004] At present, in order to reduce the use cost of digital printing machines, some manufacturers need to reverse the cardboard after printing when forming a production line with a digital printing machine before continuing production. During the reversing process, whether it is through a reversing machine or manual reversing, the cost of the production process is increased, and the space required for production is also increased.

[0005] Therefore, a technical solution is urgently needed to solve the above technical problems. Summary of the invention

DETAILED DESCRIPTION

[0045] In order to facilitate the understanding of those skilled in the art, the present invention is further described below in conjunction with the embodiments and drawings, and the contents mentioned in the embodiments are not intended to limit the present invention. The present invention is described in detail below in conjunction with the drawings.

[0046] like Fig.14 As shown in FIG. 1 , the cardboard 800 is processed by the device. During the processing, the cardboard 800 is processed as follows. Fig.14 As shown in the vertical conveying, the width of the paper passing through the device is small. Therefore, in the process of printing by the digital printing press, the width of the paper passing through the digital printing press is small, which can reduce the number of nozzles used and reduce the cost of using the digital printing press. When the paperboard 800 is conveyed vertically, as shown in the vertical conveying, Fig.14As shown, the notches 804 defining the bottom and top parts of the carton on the cardboard 800 are extended in the transverse direction of the cardboard 800. At the same time, the folding line 803 used to fold the carton is also extended in the transverse direction of the cardboard 800 and connects two corresponding notches 804, and the box height line 802 defining the height of the carton is set in the vertical direction of the cardboard 800. Therefore, the cardboard 800 of this structure is different from being processed by a conventional slotting machine. The present device can process the cardboard 800 that is fed vertically by setting the slotting roller group 30 and the contact line roller group 50, so that it can be better adapted to the digital printing machine, avoiding the conventional slotting and die-cutting processing and then performing the reversing operation on the cardboard 800, which can improve the continuity and efficiency of production and reduce the use cost of the digital printing machine.

[0047] The embodiment of the present invention provides a vertical creasing and slotting machine for a digital printing machine. By extending the cutter 330 along the axial direction of the cutter seat 321, during the round creasing and slotting operation of the upper cutter shaft 310 and the lower cutter shaft 320, the cutter 330 extending along the axial direction can cut the cardboard 800 to form a slot 804 extending in the transverse direction, thereby completing the slotting process of the vertically transported cardboard 800. At the same time, the line contact knife 521 is arranged along the axial direction of the lower line contact roller 520, thereby also completing the A folding line 803 extending in the transverse direction of the cardboard 800 is processed on the cardboard 800. Through the above-mentioned arrangement, the slotting and line-touching processing of the vertically conveyed cardboard 800 can be quickly completed, so that the vertically conveyed cardboard 800 can be processed to achieve higher adaptability to the digital printing machine, so that the number of nozzles used in the digital printing machine can be reduced during the printing process, thereby reducing the use cost of the printing machine, and there is no need to perform the reversing operation of the cardboard 800, thereby improving the continuous production efficiency of the processing.

[0048] Specifically, Figure 1-8As shown, the present embodiment provides a vertical crimping and grooving machine for a digital printing machine, comprising two wall panels 10 opposite to each other, wherein a crimping roller group 20, a grooving roller group 30, a paper belt roller group 40 and a line contact roller group 50 with a circular crimping structure are sequentially arranged between the wall panels 10 along the conveying direction of the cardboard 800, wherein the grooving roller group 30 comprises: an upper knife shaft 310, a lower knife shaft 320 and a knife seat 321, specifically, both ends of the upper knife shaft 310 are rotatably connected to the wall panel 10, and a rubber pad 311 is arranged around the circumference of the upper knife shaft 310; both ends of the lower knife shaft 320 are rotatably connected to the wall panel 10, and are arranged side by side with the upper knife shaft 310 in the up and down direction; the knife seat 321 comprises two, and both are slidably connected to the lower knife shaft 320 along the axial direction of the lower knife shaft 320, and the knife seat 321 is provided with four The cutters 330 are arranged at intervals in the circumferential direction, and the cutters 330 are extended along the axial direction of the lower cutter shaft 320. The cutters 330 include two blades 331 facing each other, and a receiving groove 332 is arranged between the blades 331. A filling piece 340 is arranged in the receiving groove 332, and the filling piece 340 is used to fill the receiving groove 332. An elastic structure is arranged on the filling piece 340. When the upper knife roller and the lower knife roller roll against each other to cut the cardboard 800, the cut cardboard 800 corresponding to the receiving groove 332 presses the elastic structure to make it elastically deformed, so that the waste is squeezed and embedded in the receiving groove 332 during processing. After the cutter 330 is separated from the slotted cardboard 800, the waste embedded in the receiving groove 332 is elastically pushed out.

[0049] During the processing of the cardboard 800, the cardboard 800 is placed vertically and passes through the crimping roller group 20, the slotting roller group 30, the paper belt roller group 40 and the line contact roller group 50 in sequence. In the process of passing through the crimping roller group 20, the cardboard 800 is rolled by the crimping roller group 20 to process a box height line 802 extending along the vertical direction of the cardboard 800. In the process of passing through the slotting roller group 30, the slotting roller group 30 performs slotting processing on the cardboard 800 to process a box height line 802 extending along the horizontal direction of the cardboard 800. The extended slot 804, the belt line roller group includes two rollers arranged side by side in the vertical direction, the two rollers roll against each other to pull the cardboard 800 to move in this setting, so as to complete the auxiliary traction and conveying work of the cardboard 800; when the cardboard 800 passes through the line contact roller group 50, the line contact knife 521 installed on the lower line contact roller 520 performs line contact processing on the cardboard 800, so as to process a folding line 803 extending along the transverse direction of the cardboard 800 and connecting two corresponding slots 804. The upper knife shaft 310 and the lower knife shaft 320 roll against each other to complete the slotting process of the cardboard 800. Specifically, during the process of the upper knife shaft 310 and the lower knife shaft 320 performing the round-to-round slotting process, the four cutters 330 installed on the knife seat 321 complete the rolling corresponding to the upper knife shaft 310, so as to process the cardboard 800 passing between the rubber pad 311 and the knife seat 321 during the rolling process, as shown in the figure. Fig.14 As shown, it can be known that four cutting operations are required on the cardboard 800, which are the first cutting of the end of the cardboard 800, and then the cutting of the three pairs of transversely extending notches 804 on the cardboard 800. That is to say, the continuous rolling of the knife holder 321 can complete the processing of the transversely extending notches 804 on the cardboard 800; when the knife holder 321 rolls, the cutter 330 cuts the cardboard 800, thereby cutting the notches 804 on the cardboard 800. In order to facilitate straight-line folding, the notches 804 have a certain width. Therefore, as shown in FIG. Figure 8As shown, the cutter 330 includes two blades 331 opposed to each other. The two blades 331 opposed to each other and spaced apart can process the slot 804 with a certain width requirement. At the same time, a receiving groove 332 is spaced apart between the blades 331. During the cutting process, since there is a certain gap between the two blades 331, when the cardboard 800 is cut, the cardboard 800 is cut by the two blades 331 and waste is generated between the two blades 331. At this time, the waste generated when the cardboard 800 is cut is stored in the receiving groove 332. In order to prevent the waste from accumulating in the receiving groove 332 and filling the receiving groove 332 to affect the subsequent slotting, Operation, a filling piece 340 is arranged in the receiving groove 332, and the filling piece 340 is used to fill the receiving groove 332, and an elastic structure is arranged on the filling piece 340. When the upper knife roller and the lower knife roller roll against each other to cut the cardboard 800, the cut cardboard 800 corresponding to the receiving groove 332 presses the elastic structure to make it elastically deformed, so that the waste is squeezed and embedded in the receiving groove 332 during processing. After the cutter 330 is separated from the slotted cardboard 800, the elastic structure releases elastic potential energy to elastically push out the waste embedded in the receiving groove 332, so that the space in the receiving groove 332 can be emptied, which can facilitate the storage of newly generated waste when the cardboard 800 is processed next time.

[0050] By setting the grooving roller group 30 through the technical solution, the groove 804 extending along the horizontal direction of the vertically transported cardboard 800 can be completed. At the same time, during the grooving process of the cardboard 800, the waste material can be automatically removed to prevent the waste material from clogging the receiving groove 332, thereby ensuring the smooth progress of the grooving process.

[0051] like Fig.14As shown, at the end of the cardboard 800 is the connecting portion 801 of the cardboard 800. After folding into a carton, the connecting portion 801 is connected to the other end of the carton by nailing or gluing to form a box body. During the processing of the connecting portion 801, the parts at both ends of the connecting portion 801 in the transverse direction are cut off to form a part extending beyond the cardboard 800. The part constitutes the connecting portion 801 used to connect to the other end of the cardboard 800. In order to facilitate the processing of the connecting portion 801, one of the four cutters 330 installed on the knife seat 321 is set as a corner knife 333. The corner knife 333 includes a main body 3331 and an inclined portion 3332, wherein the inclined portion 3332 is extended along the axial direction of the knife seat 321; one end of the inclined portion 3332 is formed at the end of the outer side of the main body 3331, and the other end is inclined toward one side of the main body 3331. During the processing of the connecting portion 801, the main body 3331 cuts the cardboard 800 along the horizontal direction, and the inclined portion 3332 cuts along the direction forming an angle with the horizontal direction, thereby cutting off a part of the end of the cardboard 800, and the remaining part constitutes the connecting portion 801. It is worth noting that in this embodiment, the structure of the corner knife 333 can be the same as that of the other three cutters 330, or it can be a single thin-sheet tool with a blade arranged on its upper part to cut the cardboard 800.

[0052] In this embodiment, the filling piece 340 installed in the receiving groove 332 can be made of high-resilience sponge, one end of the high-resilience sponge is clamped on the bottom of the receiving groove 332, and the other end is at the same level as the end of the blade 331.

[0053] During the slotting process, the waste material formed by the cutter 330 on the cardboard 800 is embedded in the receiving groove 332 under the action of the rubber pad 311. At this time, it squeezes the sponge to make it elastically deform, so as to complete the cutting process of the notch 804. After the knife shaft 320 rotates under the knife seat 321, so that the cutter 330 and the cardboard 800 are separated from each other, the sponge releases its elastic potential energy to elastically push out the waste material in the receiving groove 332, thereby emptying the receiving groove 332, so as to facilitate the next slotting process.

[0054] In another embodiment, the filler 340 includes a base and a top plate 342, wherein the base is fixedly mounted at the bottom of the receiving groove 332; the top plate 342 is located in the receiving groove 332 and above the base, and an elastic structure is arranged between the base and the top plate 342 to elastically support the top plate 342 and make the top plate 342 at the same level as the end of the blade 331. In this embodiment, the top plate 342 closes the receiving groove 332, so that foreign matter can be prevented from entering the receiving groove 332 and interfering with the elastic structure during the non-grooving process. At the same time, the cutter 330 can have a larger contact surface during the contact between the cutter 330 and the paperboard 800, thereby ensuring the stability of the groove processing of the paperboard 800. When the cutter seat 321 rotates with the lower cutter shaft 320, the cutter 330 gradually presses the paperboard 800 so that the paperboard 800 is cut by the cutter 330 under the action of the rubber pad 311. At this time, the cut waste is pressed against the rubber pad 311. The elastic structure is compressed to cause elastic deformation, thereby causing the top plate 342 to move toward the inside of the receiving groove 332, so that the waste can be embedded in the receiving groove 332. As in the previous embodiment, after the cutter 330 and the paperboard 800 are separated from each other, the elastic structure releases elastic potential energy to elastically push the waste out of the receiving groove 332. In this embodiment, the top plate 342 is made of hard material, so that it has a certain strength. In the process of releasing the elastic potential energy of the elastic structure, the top plate 342 can be moved and lifted up at various positions, so that all the waste in the receiving groove 332 can be pushed out.

[0055] In this embodiment, the elastic structure includes a plurality of springs 343 arranged side by side along the length direction of the receiving groove 332 , and two ends of the spring 343 are fixedly connected to the base and the top plate 342 respectively.

[0056] In this embodiment, in order to facilitate the replacement of the rubber pad 311, a rubber pad seat 312 corresponding to the knife seat 321 is provided on the upper knife shaft 310, and the rubber pad seat 312 is slidably connected to it along the axial direction of the upper knife shaft 310, and the rubber pad 311 wraps the circumferential surface of the rubber pad seat 312.

[0057] In this embodiment, the slotting roller group 30 also includes a slotting drive mechanism 350, which includes a slotting servo slotting motor 351 installed on any wallboard 10, and the slotting servo motor 351 is transmission-connected to the lower cutter shaft 320, and the slotting drive mechanism 350 also includes a transmission mechanism for transmitting and connecting the upper cutter shaft 310 and the lower cutter shaft 320, so that the upper cutter shaft 310 and the lower cutter shaft 320 rotate synchronously. By using the servo motor 351 as a driving device, the rotation speed of the lower cutter shaft 320 can be adjusted promptly and quickly, so that the four cutters 330 located on the cutter seat 321 can cut the cardboard 800 at different positions, that is, it can adapt to the processing of cardboards 800 of different vertical lengths.

[0058] In this embodiment, in order to facilitate the installation of the cutter 330, as shown in FIG. Figure 5-7 As shown, the knife seat 321 includes a seat body 322, and the seat body 322 is slidably connected to the lower knife shaft 320 along the axial direction of the lower knife shaft 320. Four mounting positions 323 are opened on the circumferential surface of the seat body 322. The mounting positions 323 are opened along the axial direction of the seat body 322, and include a mounting surface 324 arranged along the radial direction of the seat body 322 and an avoidance surface 325 intersecting with the mounting surface 324 and forming an angle. The cutter 330 is detachably mounted on the mounting surface 324 by fasteners.

[0059] During the installation of the cutter 330, a plurality of mutually spaced installation holes are provided along the length of the bottom of the cutter 330, and threaded holes with the same spacing distance as the installation holes are provided on the installation surface 324. The cutter 330 is fixed to the installation surface 324 of the installation position 323 by bolts. In order to facilitate the loading and unloading of the cutter 330, an avoidance surface 325 is provided on the other side of the installation position 323 to facilitate the operation of the bolts.
