Description

Technical Field

[0001] This invention relates to the field of packaging paper box processing technology, and more specifically, to a fully automatic high-speed water-based ink printing machine for packaging paper boxes. Background Technology

[0002] A high-speed water-based ink printer is a device specifically designed for water-based ink printing on corrugated cardboard. Its advantages lie in its high-speed, high-precision printing capabilities and the use of environmentally friendly water-based inks, which improves print quality while reducing environmental impact. Furthermore, its high degree of automation and high production efficiency significantly reduce labor costs.

[0003] Existing fully automatic high-speed water-based ink printing machines generally include a paper feeding section, a printing section, a slotting section, and a die-cutting section. The paper feeding section is used to transport corrugated cardboard to the printing section, which is used for multi-color printing such as four-color printing. The slotting and die-cutting sections are used for slotting and die-cutting the corrugated cardboard, respectively. Corrugated cardboard printed by a high-speed water-based ink printing machine can be directly folded into boxes for packaging.

[0004] The existing high-speed water-based ink printing press uses a leading-edge wheel feeding system, which means that corrugated cardboard is manually stacked at the feeding position and then fed by rollers. The corrugated cardboard is stacked quite high, with the upper corrugated cardboard pressing down on the lower corrugated cardboard. When the rollers feed the paper, the pressure between the rollers and the bottom corrugated cardboard is relatively large. During the feeding process, the rollers will leave rows of wheel marks on the corrugated cardboard, which reduces the appearance of the finished product. Summary of the Invention

[0005] The present invention provides a fully automatic high-speed water-based ink printing machine for packaging paper boxes. The problem to be solved is that when corrugated cardboard is stacked at a high height, the pressure between the roller and the bottom corrugated cardboard is relatively large. When feeding paper, the roller will press a row of wheel marks on the corrugated cardboard, which reduces the appearance of the finished product.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a fully automatic high-speed water-based ink printing machine for packaging cartons, comprising a paper feeding section and a printing section. A leading-edge wheel-type paper feeding device is provided on the inner side of the paper feeding section, which is used to feed corrugated paper to the printing section. A back plate is provided above the leading-edge wheel-type paper feeding device, and the back plate is fixedly installed on the paper feeding section. The bottom of the back plate has a back support plate, and a back groove is formed on the rear side of the back support plate. A rear pusher assembly is provided on the rear side of the back plate. Side positioning devices are provided on both sides of the back plate. Each side positioning device includes a side plate, and the bottom of the side plate has a side support plate. A side pusher assembly is provided on the side of the side plate away from the side support plate. Paper assembly; both side positioning devices are equipped with front positioning devices at their front ends. The front positioning device includes a front plate with a front pressure plate at the bottom. The space between the front pressure plate and the side support plate is a paper holding space. The back support plate and the two side support plates are used to support the corrugated paper together. When supporting the corrugated paper, the corrugation direction of the corrugated paper is perpendicular to the front surface of the back plate. The front plate is used to block the front side of the corrugated paper. When conveying the corrugated paper, the rear paper pusher assembly pushes the bottom corrugated paper away from the back support plate from the back groove position, so that the front end of the corrugated paper enters the interior of the paper holding space. Then, the side paper pusher assemblies on both sides push the corrugated paper towards the middle, so that the corrugated paper bends downward and detaches from the side support plate.

[0007] In a preferred embodiment, the back push paper assembly includes a linear drive component, the output end of which is fixedly connected to a back push plate, which is aligned with the back groove.

[0008] In a preferred embodiment, a side push plate is movably inserted into the side of the side plate, the lower surface of the side push plate coincides with the upper surface of the side support plate, a push rod is installed on the side push plate, a spring is sleeved on the push rod, the two ends of the spring are respectively pressed into the side push plate and the push rod, and an inclined rod is movably inserted into the upper end of the push rod.

[0009] In a preferred embodiment, one end of the slant bar is fixedly connected to a drive rod, and the rear paper pusher assembly also includes a mounting shaft, which is fixedly connected to the rear pusher plate, and one end of the drive rod is sleeved on the mounting shaft.

[0010] In a preferred embodiment, a rotating shaft is rotatably connected to the front pressure plate, and a cam is fixedly installed at the end of the rotating shaft away from the side plate. The cam is used to press down the corrugated paper located inside the paper-containing space, thereby causing the corrugated paper to bend and deform downward.

[0011] In a preferred embodiment, a gear is fixedly mounted on the end of the rotating shaft away from the cam, and a rack is fixedly connected to the end of the drive rod, with the rack meshing with the gear.

[0012] In a preferred embodiment, a passage is provided on the side wall of the front panel, and a pressure rod is rotatably connected to the pivot at the position of the passage via an elastic member. The elastic member is used to reset the pressure rod to the front panel. A baffle is vertically inserted into the front panel, the bottom of the baffle extends into the interior of the passage, and the upper end of the pressure rod abuts against the bottom of the baffle. The surface of the pressure rod near the side panel coincides with the side of the side support plate.

[0013] In a preferred embodiment, a groove is provided at the upper end of the side plate, and a slider is fixedly connected to one side of the front plate. The slider is slidably disposed inside the groove and is fixed to the groove by bolts.

[0014] In a preferred embodiment, the leading edge wheel type paper feeding device includes a paper feeding table, a rotary drive component 1 is mounted on one side of the paper feeding table, a transmission shaft is mounted on the output end of the rotary drive component 1, and a plurality of rollers are mounted on the transmission shaft, with the rollers protruding from the surface of the paper feeding table.

[0015] In a preferred embodiment, the fully automatic high-speed water-based ink printing machine further includes an adjustment device, which includes a guide shaft, a lead screw, and a second rotary drive component.

[0016] The technical effects and advantages of this invention are as follows: By setting up a back plate, a side positioning device, and a front positioning device, the corrugated paper is stacked on the back support plate and the side support plate. When feeding the paper, it can be fed to the front edge wheel paper feeding device one piece at a time, so that too much corrugated paper will not be piled up on the front edge wheel paper feeding device. When the rollers of the front edge wheel paper feeding device feed the paper, the pressure between the rollers and the corrugated paper is relatively small, and no rows of wheel marks will be pressed into the corrugated paper, thus ensuring the aesthetics of the finished product.

[0028] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0029] Refer to the instruction manual appendix Figures 1-10A fully automatic high-speed water-based ink printing machine for packaging paper boxes includes, in sequence, a paper feeding section 1, a printing section 11, a slotting section 12, and a die-cutting section 13. The printing section 11 is used to print on corrugated paper 8, the slotting section 12 is used for slotting, and the die-cutting section 13 is used for die-cutting. A leading edge wheel type paper feeding device 7 is provided on the inner side of the paper feeding section 1, which is used to feed the corrugated paper 8 to the printing section 11.

[0030] A back plate 2 is provided above the leading edge wheel type paper feeding device 7. The back plate 2 is fixedly installed on the paper feeding part 1. The bottom of the back plate 2 has a back support plate 21. A back groove 22 is opened on the rear side of the back support plate 21. A rear paper pusher assembly 6 is provided on the rear side of the back plate 2. Side positioning devices 3 are provided on both sides of the back plate 2. The side positioning device 3 includes a side plate 31. The bottom of the side plate 31 has a side support plate 311. A side paper pusher assembly 32 is provided on the side of the side plate 31 away from the side support plate 311. A front positioning device 4 is provided at the front end of each of the two side positioning devices 3. The front positioning device 4 includes a front plate 41. The bottom of the front plate 41 has a front pressure plate 411. The space between the front pressure plate 411 and the side support plate 311 is a paper holding space 5.

[0031] The back support plate 21 and the two side support plates 311 are used to support the corrugated paper 8 together. When supporting the corrugated paper 8, the corrugation direction of the corrugated paper 8 is perpendicular to the front surface of the back plate 2. The front plate 41 is used to block the front side of the corrugated paper 8. When conveying the corrugated paper 8, the rear paper pusher assembly 6 pushes the bottom corrugated paper 8 away from the back support plate 21 from the back groove 22, so that the front end of the corrugated paper 8 enters the interior of the paper holding space 5. Then, the side paper pusher assemblies 32 on both sides push the corrugated paper 8 towards the middle, so that the corrugated paper 8 bends downward and gets off the side support plate 311.

[0032] In the above technical solutions, such as Figure 4 As shown, the rear paper pusher assembly 6 includes a linear drive component 61, and a rear pusher plate 62 is fixedly connected to the output end of the linear drive component 61. The rear pusher plate 62 is aligned with the back groove 22.

[0033] It should be noted that the linear drive component 61 is a cylinder, which can drive the rear push plate 62 to push the bottom corrugated paper 8 from the position of the back groove 22.

[0034] In the above technical solutions, such as Figures 2-4 As shown, a side push plate 321 is movably inserted into the side of the side plate 31. The lower surface of the side push plate 321 coincides with the upper surface of the side support plate 311. A push rod 322 is installed on the side push plate 321. A spring 323 is sleeved on the push rod 322. The two ends of the spring 323 are pressed against the side push plate 321 and the push rod 322 respectively. A diagonal rod 325 is obliquely inserted into the upper end of the push rod 322.

[0035] Furthermore, one end of the inclined rod 325 is fixedly connected to a drive rod 324, and the rear paper pusher assembly 6 also includes a mounting shaft 63, which is fixedly connected to the rear pusher plate 62, and one end of the drive rod 324 is sleeved on the mounting shaft 63.

[0036] It should be noted that the linear drive component 61 can simultaneously drive the rear push plate 62 and the mounting shaft 63 to move. The mounting shaft 63 can drive the drive rod 324 to move. The drive rod 324 drives the inclined rod 325 to move. The inclined rod 325 can drive the push rod 322 and the side push plate 321 to move, so that the side push plate 321 can push the bottom layer of corrugated paper 8, causing it to bend and detach from the side support plate 311.

[0037] In this embodiment, the implementation method is as follows: the initial state is as follows Figure 3 , Figure 4 and Figure 6 As shown, the rear push plate 62 does not enter the back groove 22, while the side push plate 321 is located on the side support plate 311. During printing, corrugated paper 8 is first stacked, so that the back support plate 21 and the two side support plates 311 jointly support the back groove 22. The front positioning device 4 blocks the front side of the corrugated paper 8 but does not block the bottom corrugated paper 8. During paper feeding, firstly, the linear drive component 61 drives the rear push plate 62 and the mounting shaft 63 to move simultaneously. The mounting shaft 63 first drives the drive rod 324 and the diagonal rod 325 to move, as... Figure 5 As shown, the diagonal bar 325 pushes the push rod 322 to move the side push plate 321 away from the side plate 31, causing the side push plate 321 to disengage from the side support plate 311. Immediately afterwards, the rear push plate 62 enters from the back groove 22 and pushes the bottom corrugated paper 8 to move, causing the corrugated paper 8 to disengage from the back support plate 21 and enter the paper holding space 5. In this way, the bottom corrugated paper 8 is only supported by the two side support plates 311. Then, the linear drive component 61 drives the rear push plate 62 and the mounting shaft 63 back. At this time, the mounting shaft 63, through the drive rod 324, the diagonal rod 325, and the push rod 322, drives the side push plate 321 to move towards the side support plate 311, thereby pushing the end of the corrugated paper 8, causing the middle part of the corrugated paper 8 to bend downwards until the corrugated paper 8 detaches from the side support plate 311. In this way, the bottom layer of corrugated paper 8 falls onto the leading edge wheel paper feeding device 7, and is then transported to the printing section 11 by the leading edge wheel paper feeding device 7. Repeating the above operation allows for continuous paper feeding.

[0038] It should be noted that when stacking the corrugated paper 8, the corrugation direction of the corrugated paper 8 should be perpendicular to the front surface of the back plate 2. In this way, when the two side push plates 321 push the two ends of the corrugated paper 8, the bending resistance of the corrugated paper 8 is weak, and the corrugated paper 8 is easy to bend downward. However, if the corrugation direction of the corrugated paper 8 is parallel to the front surface of the back plate 2, then when the two ends of the corrugated paper 8 are pushed, the bending resistance of the corrugated paper 8 is strong, and it is not easy to bend downward. If it bends downward, it will damage the corrugated paper 8 and cause bending marks on the corrugated paper 8.

[0039] It should also be noted that, since the corrugation direction of the corrugated paper 8 is perpendicular to the front surface of the back plate 2, and there are a large number of corrugated paper 8 stacked together, the bottom layer of corrugated paper 8 is prone to bending. The number and degree of bending are uncertain. When the pusher plate 62 pushes, it may push more pieces of corrugated paper 8 to move. Some of the corrugated paper 8 may press against the front plate 41 and cause damage. The back support plate 21 can support the corrugated paper 8, making it less prone to bending and preventing such problems.

[0040] The above technical solution, through the setting of the back plate 2, the side positioning device 3 and the front positioning device 4, stacks the corrugated paper 8 on the back support plate 21 and the side support plate 311. When feeding paper, it can be fed to the front edge wheel paper feeding device 7 one by one, so that too much corrugated paper 8 will be piled up on the front edge wheel paper feeding device 7. When the roller 73 of the front edge wheel paper feeding device 7 feeds paper, the pressure between the roller 73 and the corrugated paper 8 is relatively small, and no rows of wheel marks will be pressed on the corrugated paper 8, thus ensuring the aesthetics of the finished product.

[0041] Refer to the instruction manual appendix Figures 2-6 When the two side push plates 321 push the two ends of the corrugated paper 8 to bend it, it may be difficult for the two side push plates 321 to bend the corrugated paper 8 because the corrugated paper 8 itself does not bend downwards, which may easily cause compression damage to the two ends of the corrugated paper 8. Therefore, the following technical solution is further proposed:

[0042] Specifically, such as Figure 4 and Figure 5 As shown, a rotating shaft 42 is rotatably connected to the front pressure plate 411. A cam 43 is fixedly installed at the end of the rotating shaft 42 away from the side plate 31. The cam 43 is used to press down the corrugated paper 8 located inside the paper-containing space 5, thereby causing the corrugated paper 8 to bend and deform downward.

[0043] Furthermore, a gear 44 is fixedly mounted on the end of the rotating shaft 42 away from the cam 43, and a rack 45 is fixedly connected to the end of the drive rod 324, with the rack 45 meshing with the gear 44.

[0044] It should be noted that when the rear push plate 62 pushes the corrugated paper 8 into the paper-containing space 5, the two side push plates 321 push the corrugated paper 8, and the drive rod 324 can also drive the rack 45 to move. The rack 45 drives the rotating shaft 42 and the cam 43 to rotate through the gear 44. The protruding part of the cam 43 pushes the corrugated paper 8 downward, causing the corrugated paper 8 to bend downward. In this way, when the side push plate 321 pushes the corrugated paper 8, it can directly push the corrugated paper 8 downward without causing squeezing and damage to the two ends of the corrugated paper 8.

[0045] Refer to the instruction manual appendix Figure 10 When the two side push plates 321 push the bottom corrugated paper 8 away from the side support plate 311, the two ends of the corrugated paper 8 may be squeezed and stuck against the two sides of the side support plate 311, causing it to be unable to fall. When there is corrugated paper 8 above, the next corrugated paper 8 will push the stuck corrugated paper 8 downward. However, when there is no corrugated paper 8 above, the corrugated paper 8 may not be able to fall. Therefore, the following technical solution is further proposed:

[0046] like Figures 5-7 and Figure 10 A passage 410 is provided on the side wall of the front plate 41. A pressure rod 46 is rotatably connected to the pivot 42 at the position of the passage 410 via an elastic member. The elastic member is used to reset the pressure rod 46 towards the front plate 41. A baffle 47 is vertically inserted into the front plate 41. The bottom of the baffle 47 extends into the interior of the passage 410, and the upper end of the pressure rod 46 abuts against the bottom of the baffle 47. The surface of the pressure rod 46 near the side plate 31 coincides with the side of the side support plate 311.

[0047] It should be noted that the elastic component is a torsion spring. Under normal conditions, the upper end of the pressure rod 46 is in contact with the lower end of the baffle 47. When the last piece of corrugated paper 8 is stuck, the worker can pull down the baffle 47 to disengage it from the pressure rod 46. In this way, the pressure rod 46 swings downward under the action of the torsion spring, pushing the end of the corrugated paper 8 (such as...) Figure 10 (In the direction of the arrow shown), the corrugated paper 8 is disengaged from the side support plate 311. After the machine is stopped, the staff can reset the baffle 47 and the pressure rod 46.

[0048] Refer to the instruction manual appendix Figure 1 and Figure 8 The leading edge wheel type paper feeding device 7 includes a paper feeding table 71. A rotary drive component 72 is installed on one side of the paper feeding table 71. A transmission shaft is installed at the output end of the rotary drive component 72. Several rollers 73 are installed on the transmission shaft. The rollers 73 protrude from the surface of the paper feeding table 71.

[0049] It should be noted that the rotary drive component 72 is a motor. The rotary drive component 72 drives the transmission shaft and roller 73 to rotate, thereby conveying the corrugated paper 8 towards the printing section 11.

[0050] Refer to the instruction manual appendix Figures 2-4 The fully automatic high-speed water-based ink printing machine also includes an adjustment device 9, which includes a guide shaft 91, a lead screw 92, and a rotary drive component 93. Both ends of the guide shaft 91 and the lead screw 92 are mounted on the paper feeding part 1. The rotary drive component 93 is used to drive the lead screw 92 to rotate. The side plate 31 of one side positioning device 3 is movably sleeved on the guide shaft 91 and threadedly connected to the lead screw 92. The side plate 31 of the other side positioning device 3 is fixedly mounted on the guide shaft 91.

[0051] It should be noted that the rotary drive component 2 93 is a motor. The rotary drive component 2 93 drives the side plate 31 to move, and the position of this side positioning device 3 can be adjusted so as to adapt to corrugated paper 8 of different lengths.

[0052] Refer to the instruction manual appendix Figure 5 The upper end of the side plate 31 is provided with a sliding groove 312, and a slider 412 is fixedly connected to one side of the front plate 41. The slider 412 is slidably disposed inside the sliding groove 312 and is fixed to the sliding groove 312 by bolts.

[0053] It should be noted that the slider 412 can be adjusted in position inside the groove 312, so as to accommodate corrugated paper 8 of different widths.

[0054] In conclusion, the above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
