Description

Technical Field

[0001] This utility model relates to the technical field of corrugated cardboard box processing equipment, specifically to a vertical corrugated paper slotting machine applied to a digital printing machine. Background Technology

[0002] With the gradual advancement of technology, digital printing presses have developed rapidly. The emergence of digital printing presses has improved the printing quality of cartons, enabling the printing of richer patterns, and 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 printheads. In other words, the more printheads used, the higher the cost. This is reflected in the fact that the wider the printed material, the more printheads are needed, leading to higher operating costs.

[0003] Currently, traditional corrugated cardboard processing equipment uses transverse paper feeding. This means that slotting and die-cutting machines feed paper transversely to perform slotting and die-cutting on the transversely conveyed cardboard. Specifically, a current slotting machine includes two vertically arranged and interconnected shafts. One shaft is equipped with four cutter holders, which can slide along the shaft, allowing adjustment of the spacing between the cutter holders to accommodate cardboard of different widths. The cutter holders are equipped with arc-shaped cutters, which slot the cardboard during the circular pressing action of the two shafts, creating slots in the same direction as the conveying flow. Therefore, when using digital printing presses, because slotting and die-cutting machines feed paper transversely, the cardboard input to the digital printing press is always placed transversely. This necessitates the use of more printheads to print on the transversely conveyed cardboard, leading to increased printing costs.

[0004] Currently, in order to reduce the operating costs of digital printing machines, some manufacturers need to reverse the direction of the cardboard after printing when forming a production line with digital printing machines before they can continue production. During the reversal process, whether it is done by a reversal machine or manually, the cost of production is increased, and the space required for production is also increased.

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

[0006] The purpose of this utility model is to provide a vertical corrugated paper slotting machine for use in digital printing presses, in order to solve the above-mentioned technical problems. The utility model adopts the following technical solution:

[0007] A vertical corrugated paper slotting machine for use in a digital printing press includes two opposing wall panels. Between the wall panels, along the paperboard conveying direction, are sequentially arranged a crease roller group, a slotting roller group, a paper-carrying roller group, and a crease-contact roller group with a circular-to-circular structure. The slotting roller group includes:

[0008] An upper cutter shaft, the two ends of which are rotatably connected to the wall panel, and a rubber pad is arranged around the circumference of the upper cutter shaft;

[0009] The lower cutter shaft is rotatably connected at both ends to the wall panel and is arranged side by side with the upper cutter shaft in the vertical direction;

[0010] The blade holder comprises two blades, each slidably connected to the lower blade shaft along its axial direction. Each blade holder has four circumferentially spaced cutters extending along the axial direction of the lower blade shaft. Each cutter includes two opposing blades with a receiving groove spaced between them. A filler is provided within the receiving groove to fill it, and an elastic structure is provided on top of the filler. When the upper and lower blade rollers roll against each other to cut the cardboard, the cardboard cut and corresponding to the receiving groove presses against the elastic structure, causing it to deform elastically. This forces the waste material into the receiving groove during processing. After the cutter separates from the slotted cardboard, the waste material embedded in the receiving groove is elastically ejected.

[0011] Furthermore, the filling material is made of high-resilience sponge, with one end of the high-resilience sponge snapped into the bottom of the receiving groove, and the other end at the same horizontal height as the end of the blade.

[0012] Furthermore, the filler includes:

[0013] The base is fixedly mounted at the bottom of the receiving groove;

[0014] A top plate is located within the receiving groove and above the base, and the elastic structure is disposed between the base and the top plate to elastically support the top plate and position the top plate at the same horizontal height as the end of the blade.

[0015] Furthermore, the elastic structure includes a plurality of springs arranged side by side along the length of the receiving groove, with the two ends of the springs fixedly connected to the base and the top plate, respectively.

[0016] Furthermore, one of the cutters is configured as a corner cutter, the corner cutter comprising:

[0017] The main body extends along the axial direction of the tool holder;

[0018] An inclined portion, one end of which is formed on the outer side of the main body portion, and the other end is inclined toward one side of the main body portion.

[0019] Furthermore, a rubber pad corresponding to the tool holder is provided on the upper tool shaft. The rubber pad is slidably connected to the upper tool shaft along its axial direction, and the rubber pad covers the circumferential surface of the rubber pad.

[0020] Furthermore, the grooving roller group also includes a grooving drive mechanism. The grooving drive mechanism includes a grooving servo motor mounted on any one of the wall panels, and the grooving servo motor is connected to the lower cutter shaft. The grooving drive mechanism also includes a transmission mechanism for transmitting and connecting the upper cutter shaft and the lower cutter shaft, so that the upper cutter shaft and the lower cutter shaft rotate synchronously.

[0021] Furthermore, the tool holder includes a body, which is slidably connected to the lower tool shaft along the axial direction of the lower tool shaft. Four mounting positions are provided on the circumferential surface of the body. Each mounting position is provided along the axial direction of the body and includes a mounting surface arranged along the radial direction of the body and a clearance surface that intersects the mounting surface and forms an angle. The cutter is detachably mounted on the mounting surface by fasteners.

[0022] Furthermore, the pressure roller assembly includes:

[0023] The upper pressure shaft is rotatably connected to the wall panel at both ends, and an upper pressure fixing seat is slidably connected to the upper pressure shaft along the axial direction. An upper pressure wheel is fixedly installed on the upper pressure fixing seat, and two mutually spaced upper pressure protrusions are formed on the circumferential surface of the upper pressure wheel along the circumferential direction.

[0024] The pressure line is a lower shaft, with both ends rotatably connected to the wall panel. A lower pressure line fixing seat is slidably connected to the lower pressure line along the axial direction. A lower pressure line wheel is fixedly installed on the lower pressure line fixing seat. A lower pressure line protrusion is formed on the circumferential surface of the lower pressure line wheel along the circumferential direction. The lower pressure line protrusion is staggered with two upper pressure line protrusions.

[0025] Furthermore, the wire-contacting roller group includes:

[0026] The upper contact roller has two ends rotatably connected to the wall panel, and the circumferential surface of the upper contact roller is covered with a contact rubber sleeve.

[0027] The lower contact roller has its two ends rotatably connected to the wall panel, and a contact blade is detachably mounted on the lower contact roller. The contact blade extends along the axial direction of the lower contact roller, and the end of the contact blade protrudes from the circumferential surface of the lower contact roller.

[0028] The beneficial effects of this utility model are as follows:

[0029] This utility model provides a vertical corrugated paper slotting machine for digital printing presses. By extending the cutter along the axis of the cutter holder, during the circular pressing and slotting operation of the upper and lower cutter shafts, the cutter extends along the axis to cut the cardboard with a horizontally extending groove, thus completing the slotting process on the vertically conveyed cardboard. Simultaneously, the crimping cutter is positioned along the axis of the lower crimping roller, which also completes the processing of folding lines extending horizontally on the cardboard. Through the above configuration, the slotting and crimping processing of the vertically conveyed cardboard can be completed quickly. This allows for higher compatibility with digital printing presses, reducing the number of printheads used during printing, thus lowering the operating cost of the printing press. Furthermore, it eliminates the need for cardboard reversal operations, improving continuous production efficiency. Attached Figure Description

Detailed Implementation

[0045] To facilitate understanding by those skilled in the art, the present invention will be further described below with reference to embodiments and accompanying drawings. The content mentioned in the embodiments is not intended to limit the present invention. The present invention will be described in detail below with reference to the accompanying drawings.

[0046] like Figure 14 As shown, this is cardboard 800 that has been processed by this equipment. During the processing, cardboard 800 passes through... Figure 14As shown, the paper is fed vertically. Since the width of the paper passing through this equipment is relatively small, during the printing process by the digital printing press, the smaller width allows for fewer printheads to be used, reducing the operating cost of the digital printing press. When the paperboard 800 is fed vertically, if... Figure 14 As shown, the slots 804 defining the bottom and top of the carton on the cardboard 800 extend in the transverse direction of the cardboard 800. Similarly, the folding lines 803 used to fold the carton also extend in the transverse direction of the cardboard 800 and connect the two corresponding slots 804. The box height line 802 defining the carton height is set in the vertical direction of the cardboard 800. Therefore, this type of cardboard 800 cannot be processed by a conventional slotting machine. This equipment, by setting up the slotting roller group 30 and the crimping roller group 50, can process the cardboard 800 that is fed vertically, thus enabling better compatibility with digital printing machines. This avoids the need for conventional slotting and die-cutting processes followed by reversing the cardboard 800, improving production continuity and efficiency, and reducing the operating costs of digital printing machines.

[0047] This utility model embodiment provides a vertical corrugated paper slotting machine applied to a digital printing press. By extending the cutter 330 along the axial direction of the cutter holder 321, during the circular pressing 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 horizontally extending slots 804 into the paperboard 800, thereby completing the slotting process on the vertically conveyed paperboard 800. At the same time, the crimping knife 521 is set along the axial direction of the lower crimping roller 520, which can also... Folding lines 803 extending in the transverse direction of the cardboard 800 are processed on the cardboard 800. Through the above settings, the slotting and creasing processing of the vertically conveyed cardboard 800 can be completed quickly. This allows for higher compatibility with digital printing machines by processing the vertically conveyed cardboard 800, thereby reducing the number of printheads used during the printing process, thus reducing the operating cost of the printing machine. Furthermore, it eliminates the need for reversing the direction of the cardboard 800, improving the continuous production efficiency of the processing.

[0048] Specifically, such as Figure 1-8As shown, this embodiment provides a vertical corrugated paper slotting machine for use in a digital printing press, comprising two opposing wall panels 10. Between the wall panels 10, along the conveying direction of the paperboard 800, are sequentially arranged a circular-to-circular pressing roller group 20, a slotting roller group 30, a paper-carrying roller group 40, and a crease-touching roller group 50. The slotting roller group 30 includes an upper cutter shaft 310, a lower cutter shaft 320, and a cutter holder 321. Specifically, the upper cutter shaft 310 is rotatably connected to the wall panel 10 at both ends, and a rubber pad 311 is arranged around its circumference. The lower cutter shaft 320 is rotatably connected to the wall panel 10 at both ends and is arranged side-by-side with the upper cutter shaft 310 in the vertical direction. Two cutter holders 321 are included, each slidably connected to the lower cutter shaft 320 along its axial direction. Each cutter holder 321 is provided with four... A pair of cutters 330 are spaced apart along the circumference and extend along the axis of the lower cutter shaft 320. Each cutter 330 includes two opposing blades 331, with a receiving groove 332 spaced between the blades 331. A filler 340 is provided inside the receiving groove 332 to fill it. An elastic structure is provided on the filler 340. When the upper and lower cutter rollers roll against each other to cut the cardboard 800, the cardboard 800 that is cut and corresponds to the receiving groove 332 presses against the elastic structure to cause it to deform elastically. This causes the waste material to be squeezed and embedded into the receiving groove 332 during processing. After the cutter 330 separates from the slotted cardboard 800, the waste material embedded in the receiving groove 332 is elastically pushed out.

[0049] During the processing of cardboard 800, cardboard 800 is placed vertically and passes sequentially through the creasing roller group 20, the slotting roller group 30, the paper-carrying roller group 40, and the creasing roller group 50. When passing through the creasing roller group 20, the cardboard 800 is rolled to create the box height line 802 extending vertically along the cardboard 800. When passing through the slotting roller group 30, the cardboard 800 is slotted, creating the box height line 802 extending horizontally along the cardboard 800. The extended slot 804 and the line roller group include two rollers arranged side by side in the vertical direction. The two rollers roll against each other to pull the cardboard 800 to move within this arrangement, thus completing the auxiliary traction and conveying work of the cardboard 800. When the cardboard 800 passes through the line-fitting roller group 50, the line-fitting knife 521 mounted on the lower line-fitting roller 520 performs line-fitting processing on the cardboard 800, thereby creating a fold line 803 that extends along the transverse direction of the cardboard 800 and connects the two corresponding slots 804. The upper knife shaft 310 and the lower knife shaft 320 roll against each other to complete the grooving processing of the cardboard 800. Specifically, during the circular pressing and grooving process of the upper knife shaft 310 and the lower knife shaft 320, four cutters 330 mounted on the knife holder 321 roll relative to the upper knife shaft 310, thereby processing the cardboard 800 passing between the rubber pad 311 and the knife holder 321 during the rolling process, as shown in the figure. Figure 14 As shown, it can be seen that the cardboard 800 requires four cutting operations. First, the end of the cardboard 800 is cut. Then, the three pairs of laterally extending slots 804 on the cardboard 800 are cut sequentially. That is, the continuous rolling of the cutter 321 completes the cutting of the laterally extending slots 804 on the cardboard 800. While the cutter 321 is rolling, the cutter 330 cuts the cardboard 800, thus creating the slots 804. Because of the need for straight folding, the slots 804 have a certain width. Therefore, as... Figure 8As shown, the cutter 330 includes two opposing blades 331. These two opposing and spaced-apart blades 331 can process a slot 804 with a certain width requirement. A receiving groove 332 is provided between the blades 331. During the cutting process, due to the gap between the two blades 331, when cutting the cardboard 800, the cardboard 800 is cut by the two blades 331, generating waste material between them. This waste material is collected in the receiving groove 332. To prevent the waste material from accumulating in the receiving groove 332 and filling it, thus affecting subsequent slotting, further processing is required. In the process, a filler 340 is provided inside the receiving groove 332 to fill the receiving groove 332. An elastic structure is provided on the filler 340. When the upper and lower cutter rollers roll against each other to cut the cardboard 800, the cardboard 800 that is cut off and corresponds to the receiving groove 332 presses against the elastic structure to cause it to deform elastically. This causes the waste material to be squeezed into the receiving groove 332 during processing. After the cutter 330 separates from the slotted cardboard 800, the elastic structure releases its elastic potential energy to elastically push out the waste material embedded in the receiving groove 332. This allows the space inside the receiving groove 332 to be emptied, making it convenient to collect newly generated waste material when the cardboard 800 is processed again.

[0050] By setting the grooving roller group 30 in this technical solution, the vertically conveyed cardboard 800 can be made to form a groove 804 that extends in the horizontal direction. 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, thus ensuring the smooth progress of the grooving process.

[0051] like Figure 14As shown, at the end of the cardboard 800 is a connecting part 801. After being folded into a carton, the connecting part 801 is connected to the other end of the carton by nailing or gluing to form a carton body. During the processing of the connecting part 801, the portions at both ends of the connecting part 801 in the lateral direction are cut off to form a portion extending beyond the cardboard 800. This portion constitutes the connecting part 801 used to connect with the other end of the cardboard 800. To facilitate the processing of the connecting part 801, one of the four cutters 330 mounted on the cutter holder 321 is set as a corner cutter 333. The corner cutter 333 includes a main body 3331 and an inclined part 3332, which extends along the axial direction of the cutter holder 321. One end of the inclined part 3332 is formed at the outer end 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 part 801, the main body 3331 cuts the cardboard 800 in the transverse direction, and the inclined part 3332 cuts in the direction forming an angle with the transverse direction, thereby cutting off a portion of the end of the cardboard 800, and the remaining part forms the connecting part 801. It is worth noting that in this embodiment, the structure of the corner knife 333 can be the same as the structure of the other three cutting knives 330, or it can be a single thin-plate knife with a blade on its upper part, thereby cutting the cardboard 800.

[0052] In this embodiment, the filler 340 installed in the receiving groove 332 can be made of high-resilience sponge. One end of the high-resilience sponge is snapped into the bottom of the receiving groove 332, and the other end is at the same horizontal height as the end of the blade 331.

[0053] During the grooving process, the waste material formed by the cutter 330 on the cardboard 800 is embedded into the receiving groove 332 under the action of the rubber pad 311. At this time, it squeezes the sponge to make it elastically deform, thereby completing the cutting process of the groove 804. After the cutter head 321 lowers the cutter shaft 320 to rotate, the cutter 330 and the cardboard 800 are separated. The sponge releases elastic potential energy to elastically push out the waste material in the receiving groove 332, thereby emptying the receiving groove 332 and making it convenient for the next grooving process.

[0054] In another embodiment, the filler 340 includes a base and a top plate 342. The base is fixedly mounted at the bottom of the receiving groove 332. The top plate 342 is located within the receiving groove 332 and above the base. An elastic structure is disposed between the base and the top plate 342 to elastically support the top plate 342 and to position the top plate 342 at the same horizontal height as the end of the blade 331. In this embodiment, the top plate 342 closes the receiving groove 332, thereby preventing foreign objects from entering the receiving groove 332 and interfering with the elastic structure during the ungrooved processing. Simultaneously, it allows the cutter 330 to have a large contact surface during its contact with the cardboard 800, ensuring the stability of the grooving process on the cardboard 800. As the cutter holder 321 rotates with the lower cutter shaft 320, the cutter 330 gradually presses against the cardboard 800, causing the cardboard 800 to be cut by the cutter 330 under the action of the rubber pad 311. At this time, the cut waste material resists the action of the rubber pad 311. The compressive elastic structure causes elastic deformation, which in turn causes the top plate 342 to move toward the inside of the receiving groove 332, thereby allowing the waste material to be embedded into the receiving groove 332. As in the previous embodiment, after the cutter 330 and the cardboard 800 separate, the elastic structure releases elastic potential energy, thereby elastically pushing the waste material out of the receiving groove 332. In this embodiment, the top plate 342 is made of a rigid material, which gives it a certain strength. During the process of the elastic structure releasing elastic potential energy, the top plate 342 can be moved and lifted at various positions, pushing out all the waste material located in the receiving groove 332.

[0055] In this embodiment, the elastic structure includes a plurality of springs 343 arranged side by side along the length of the receiving groove 332, and the two ends of the springs 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 tool holder 321 is provided on the upper cutter shaft 310. The rubber pad seat 312 is slidably connected to the upper cutter shaft 310 along the axial direction, and the rubber pad 311 covers the circumferential surface of the rubber pad seat 312.

[0057] In this embodiment, the grooving roller assembly 30 further includes a grooving drive mechanism 350. The grooving drive mechanism includes a grooving servo grooving motor 351 mounted on any of the wall panels 10, and the grooving servo motor 351 is connected to the lower cutter shaft 320. The grooving drive mechanism 350 also includes a transmission mechanism for transmitting the connection between 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 drive device, the rotation speed of the lower cutter shaft 320 can be adjusted in a timely and quick manner, thereby enabling the four cutters 330 located on the cutter holder 321 to cut the cardboard 800 at different positions, that is, it can adapt to the processing of cardboard 800 with different vertical length dimensions.

[0058] In this embodiment, to facilitate the installation of the cutter 330, such as Figure 5-7 As shown, the tool holder 321 includes a body 322, which is slidably connected to the lower tool shaft 320 along the axial direction of the lower tool shaft 320. Four mounting positions 323 are provided on the circumferential surface of the body 322. The mounting positions 323 are provided along the axial direction of the body 322 and include a mounting surface 324 arranged along the radial direction of the body 322 and a clearance surface 325 that intersects with the mounting surface 324 and forms an angle. The cutter 330 is detachably mounted on the mounting surface 324 by fasteners.

[0059] During the installation of the cutter 330, several mutually spaced mounting holes are provided along the length of the bottom of the cutter 330. Threaded holes with the same spacing as the mounting holes are provided on the mounting surface 324. The cutter 330 is fastened to the mounting surface 324 of the mounting position 323 by bolts. To facilitate the installation and removal of the cutter 330, a clearance surface 325 is provided on the other side of the mounting position 323, thereby facilitating the operation of the bolts.

[0060] like Figure 9-11 As shown, the pressure roller assembly 20 includes an upper pressure roller shaft 210 and a lower pressure roller shaft 220. The upper pressure roller shaft 210 is rotatably connected to the wall panel 10 at both ends, and an upper pressure roller fixing seat 211 is slidably connected to the upper pressure roller shaft 210 along the axial direction. An upper pressure roller 212 is fixedly installed on the upper pressure roller fixing seat 211, and two mutually spaced upper pressure roller protrusions 213 are formed on the circumferential surface of the upper pressure roller 212 along the circumferential direction. The lower pressure roller shaft 220 is rotatably connected to the wall panel 10 at both ends, and a lower pressure roller fixing seat 221 is slidably connected to the lower pressure roller shaft 220 along the axial direction. A lower pressure roller 222 is fixedly installed on the lower pressure roller fixing seat 221, and a lower pressure roller protrusion 223 is formed on the circumferential surface of the lower pressure roller 222 along the circumferential direction. The lower pressure roller protrusion 223 and the two upper pressure roller protrusions 213 are arranged alternately.

[0061] During the processing of the box height line 802 on the cardboard 800 machine, the upper pressing wheel 212 rotates with the upper pressing shaft 210, and the lower pressing wheel 222 rotates with the lower pressing shaft 220, thereby performing circular pressing and crease processing on the cardboard 800 passing between the upper pressing shaft 210 and the lower pressing shaft 220. By staggering the lower pressing ring 223 and the upper pressing ring 213, the lower pressing ring 223 can press the cardboard 800 towards the space between the two upper pressing rings 213, so that the cardboard 800 is crushed at this position to form an indentation, making the box height line 802 formation more stable and reliable.

[0062] It is worth noting that a drive device is also configured on the pressure roller group 20. This drive device consists of a servo motor and a transmission structure, which drives the upper shaft 210 and the lower shaft 220 of the pressure roller to rotate.

[0063] like Figure 12-13 As shown, the wire-contacting roller assembly 50 provided in this embodiment includes an upper wire-contacting roller 510 and a lower wire-contacting roller 520. The upper wire-contacting roller 510 is rotatably connected to the wall plate 10 at both ends, and the circumferential surface of the upper wire-contacting roller 510 is covered with a wire-contacting rubber sleeve 511. The lower wire-contacting roller 520 is rotatably connected to the wall plate 10 at both ends, and a wire-contacting knife 521 is detachably mounted on the lower wire-contacting roller 520.
