DETAILED DESCRIPTION

[0028] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

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

[0030] A back plate 2 is arranged above the leading edge wheel paper feeding device 7, and the back plate 2 is fixedly mounted on the paper feeding part 1. A back support plate 21 is provided at the bottom of the back plate 2, and a back groove 22 is provided at the rear side of the back support plate 21, and a rear paper pushing assembly 6 is arranged at the rear side of the back plate 2; side positioning devices 3 are arranged on both sides of the back plate 2, and the side positioning devices 3 include side plates 31, and the bottom of the side plates 31 include side support plates 311, and a side of the side plate 31 away from the side support plates 311 is provided with a side paper pushing assembly 32; front positioning devices 4 are arranged at the front ends of the two side positioning devices 3, and the front positioning devices 4 include a front plate 41, and the bottom of the front plate 41 includes a front pressure plate 411, and a paper holding space 5 is provided between the front pressure plate 411 and the side support plates 311.

[0031] The back support plate 21 and the two side support plates 311 are used to jointly support the corrugated paper 8, and when supporting the corrugated paper 8, the corrugated direction of the corrugated paper 8 is perpendicular to the front surface of the back plate 2, and 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 pushing assembly 6 pushes the bottom piece of corrugated paper 8 away from the back support plate 21 from the position of the back groove 22, so that the front end of the corrugated paper 8 enters the interior of the paper holding space 5, and then the side paper pushing assemblies 32 on both sides push the corrugated paper 8 toward the middle, so that the corrugated paper 8 bends downward and separates from the side support plates 311.

[0032] In the above technical solution, if Figure 4 As shown, the rear paper pushing assembly 6 includes a linear driving component 61 , an output end of the linear driving component 61 is fixedly connected with a rear pushing plate 62 , and the rear pushing plate 62 is aligned with the back groove 22 .

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

[0034] In the above technical solution, if Figure 2-Figure 4 As shown, a side push plate 321 is movably connected to the side of the side plate 31, and 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, and a spring 323 is sleeved on the push rod 322. The two ends of the spring 323 are respectively pressed against the side push plate 321 and the push rod 322, and an oblique rod 325 is obliquely movably connected to the upper end of the push rod 322.

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

[0036] It should be noted that the linear drive component 61 can drive the rear push plate 62 and the mounting shaft 63 to move at the same time, 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 to bend it and separate 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. When printing, the corrugated paper 8 is first stacked, so that the back support plate 21 and the two side support plates 311 support the back groove 22 together, and the front positioning device 4 blocks the front side of the corrugated paper 8 but does not block the bottom piece of corrugated paper 8. When feeding paper, first, the linear drive component 61 drives the rear push plate 62 and the mounting shaft 63 to move simultaneously, and the mounting shaft 63 first drives the driving rod 324 and the inclined rod 325 to move, as shown in FIG. Figure 5 As shown, the inclined rod 325 drives the side push plate 321 to move away from the side plate 31 by pushing the push rod 322, so that the side push plate 321 is separated from the side support plate 311, and then the rear push plate 62 enters from the back groove 22 and pushes the bottom piece of corrugated paper 8 to move, so that the corrugated paper 8 is separated from the back support plate 21 and enters the paper holding space 5. In this way, the bottom corrugated paper 8 is supported by only two side support plates 311. Then, the linear driving component 61 drives the rear push plate 62 and the installation shaft 63 to return. At this time, the installation shaft 63 drives the side push plate 321 to move toward the side support plate 311 through the driving rod 324, the inclined rod 325, and the push rod 322 to push the end of the corrugated paper 8, so that the middle part of the corrugated paper 8 bends downward until the corrugated paper 8 is separated from the side support plate 311. In this way, the bottom layer of corrugated paper 8 falls onto the front edge wheel paper feeding device 7, and then the front edge wheel paper feeding device 7 transports the corrugated paper 8 to the printing section 11. Repeating the above operation can continuously feed paper.

[0038] It should be noted that when stacking corrugated paper 8, the corrugated direction of the corrugated paper 8 needs to 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 weaker, and the corrugated paper 8 is easy to bend downward. If the corrugated 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 stronger, and it is not easy to bend downward. If it bends downward, the corrugated paper 8 will be damaged and the corrugated paper 8 will have bending marks.

[0039] It should also be noted that since the corrugated direction of the corrugated paper 8 is perpendicular to the front surface of the back plate 2 and a large number of corrugated paper 8 are stacked together, the bottom layer of corrugated paper 8 is easy to bend, and the amount and degree of bending are uncertain. When the push plate 62 is pushed, it is possible to push more pieces of corrugated paper 8 to move. Some corrugated paper 8 will squeeze the front plate 41 and cause damage. The setting of the back support plate 21 can support the corrugated paper 8, making it difficult for the corrugated paper 8 to bend, thereby preventing such problems.

[0040] The above technical solution stacks the corrugated paper 8 on the back support plate 21 and the side support plate 311 through the arrangement of the back plate 2, the side positioning device 3 and the front positioning device 4. When feeding paper, it can be fed piece by piece to the front edge wheel paper feeding device 7, so that too much corrugated paper 8 will not be piled 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 rows of wheel marks will not be pressed on the corrugated paper 8, thereby ensuring the aesthetics of the finished product.

[0041] Refer to the instruction manual Figure 2-Figure 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 push the corrugated paper 8 to bend it because the corrugated paper 8 itself does not bend downward, and it is easy to cause squeezing damage to the two ends of the corrugated paper 8. Therefore, the following technical solutions are further proposed: Specifically, Figure 4 and Figure 5 As shown, a rotating shaft 42 is rotatably connected to the front pressing plate 411, and a cam 43 is fixedly installed at one 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 receiving space 5, so that the corrugated paper 8 bends downward.

[0042] Furthermore, a gear 44 is fixedly mounted on one end of the rotating shaft 42 away from the cam 43 , and a rack 45 is fixedly connected to the end of the driving rod 324 , and the rack 45 is meshed with the gear 44 .

[0043] It should be noted that, after the rear push plate 62 pushes the corrugated paper 8 into the paper containing space 5, when the two side push plates 321 push the corrugated paper 8, the driving rod 324 can also drive the rack 45 to move, and the rack 45 drives the rotating shaft 42 and the cam 43 to rotate through the gear 44, and the protruding part of the cam 43 pushes the corrugated paper 8 downward to make the corrugated paper 8 bend downward. In this way, when the side push plate 321 pushes the corrugated paper 8, the corrugated paper 8 can be directly pushed and bent downward without causing squeezing damage to the two ends of the corrugated paper 8.

[0044] Refer to the instruction manual Fig.10 When the two side push plates 321 push the lowest piece of corrugated paper 8 to separate from the side support plate 311, the two ends of the corrugated paper 8 may be squeezed and stuck with the two side surfaces of the side support plate 311, causing the problem of being unable to fall. When there is still corrugated paper 8 above, the next piece of corrugated paper 8 will push the stuck corrugated paper 8 downward, and when there is no corrugated paper 8 above, the piece of corrugated paper 8 may not be able to fall. Therefore, the following technical solution is further proposed: like Figure 5-Figure 7 and Fig.10 A through hole 410 is provided on the side wall of the front plate 41, and a pressure rod 46 is rotatably connected to the through hole 410 on the rotating shaft 42 through an elastic component. The elastic component is used to reset the pressure rod 46 toward the front plate 41. A baffle 47 is vertically inserted into the front plate 41, and the bottom of the baffle 47 extends to the inside of the through hole 410, and the upper end of the pressure rod 46 abuts against the bottom of the baffle 47, and the surface of the pressure rod 46 close to the side plate 31 coincides with the side of the side support plate 311.

[0045] 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 compression contact with the lower end of the baffle 47. When the last piece of corrugated paper 8 is stuck, the staff can pull the baffle 47 downward to separate the baffle 47 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 Fig.10 The corrugated paper 8 is separated from the side support plate 311 by moving in the direction of the arrow shown in the figure. After the machine is stopped, the staff can reset the baffle 47 and the pressure rod 46.

[0046] Refer to the instruction manual Figure 1 and Figure 8 The leading edge wheel paper feeding device 7 includes a paper feeding platform 71, a rotating driving component 72 is installed on one side of the paper feeding platform 71, a transmission shaft is installed at the output end of the rotating driving component 72, and a plurality of rollers 73 are installed on the transmission shaft, and the rollers 73 protrude from the surface of the paper feeding platform 71.

[0047] It should be noted that the rotary drive component 72 adopts a motor, and the rotary drive component 72 drives the transmission shaft and the roller 73 to rotate, thereby conveying the corrugated paper 8 toward the printing unit 11.

[0048] Refer to the instruction manual Figure 2-Figure 4 The fully automatic high-speed water-based ink printing machine also includes an adjusting device 9, which includes a guide shaft 91, a screw rod 92 and a second rotating driving component 93. Both ends of the guide shaft 91 and the screw rod 92 are installed on the paper feeding part 1. The second rotating driving component 93 is used to drive the screw rod 92 to rotate. A side plate 31 of one side positioning device 3 is movably sleeved on the guide shaft 91 and is threadedly connected to the screw rod 92. The side plate 31 of the other side positioning device 3 is fixedly installed on the guide shaft 91.

[0049] It should be noted that the second rotary drive component 93 adopts a motor, and the second rotary drive component 93 drives the side plate 31 to move, so as to adjust the position of the side positioning device 3 so as to adapt to corrugated paper 8 of different lengths.

[0050] Refer to the instruction manual Figure 5 A slide groove 312 is provided at the upper end of the side plate 31, and a slider 412 is fixedly connected to one side of the front plate 41. The slider 412 is slidably arranged inside the slide groove 312, and the slider 412 is fixed to the slide groove 312 by bolts.

[0051] It should be noted that the position of the slider 412 can be adjusted inside the slide groove 312 so as to accommodate corrugated paper 8 of different widths.

[0052] Finally: 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 in the protection scope of the present invention.
