Description

Technical Field

[0001] This invention relates to an automatic paper cutting system, its installation method, and its cutting method. Background Technology

[0002] Currently, corrugated cardboard box printing mainly uses two printing methods: offset printing and flexographic direct printing. Offset printing involves laminating corrugated paper and linerboard into a single sheet of single-sided corrugated cardboard, then laminating the offset-printed linerboard onto the single-sided corrugated cardboard to form the cardboard box. Single-sheet offset printing with lamination produces high-quality, durable images and is widely used in the production of high-end colored cardboard boxes and cartons. However, the following problems hinder the further development of offset printing:

[0003] (1) Solvent-based inks contain volatile organic solvents such as toluene, gasoline, and ethyl acetate, which are toxic and flammable and cause pollution to human body, packaged goods and environment.

[0004] (2) The use of laminating adhesive to bond non-degradable plastic film after printing further aggravates environmental pollution and makes recycling more difficult, which does not meet environmental protection requirements.

[0005] (3) The production process is complex and the production cycle is long, which cannot meet the requirements of large-volume and rapid delivery.

[0006] Flexographic direct printing involves printing on a single sheet of corrugated cardboard blanks, which are composed of linerboard, corrugated paper, and face paper. Flexographic printing uses water-based inks, making it environmentally friendly. However, because it prints directly on the cardboard, the paper surface flatness is poor, printing precision is low, and the cardboard strength is reduced during the printing process. Although it is widely used by carton manufacturers in China, it ultimately struggles to meet the increasingly higher demands from customers for both packaging cost and printing quality.

Finally, pass the flexographic face paper tape through the tensioning input guide wheel, tensioning lower press guide wheel, tensioning upper push guide wheel, and tensioning output guide wheel in sequence, and adjust the elasticity of the tensioning lower pressure spring and the tensioning upper push spring.

[0022] Step D, assemble the cross-cutting device; first, install the upper cross-cutting blade on the upper cross-cutting shaft and the lower cross-cutting blade on the lower cross-cutting shaft; then, symmetrically install the upper and lower cross-cutting shafts on both sides of the flexographic printing paper tape output by the marking device.

[0023] Step E, assemble the longitudinal cutting device; first, install the longitudinal cutting platform and the longitudinal cutting rotary cutter on both sides of the flexographic printing paper tape output by the transverse cutting device;

[0024] Step F: Assemble the segmentation device. First, symmetrically install the slow-speed lower damping roller and the slow-speed upper pressure roller on both sides of the flexographic paper tape output from the slitting device. Then, symmetrically install the fast-speed lower roller and the fast-speed upper pressure roller on both sides of the flexographic paper tape output from the slow-speed lower damping roller and the slow-speed upper pressure roller. Next, adjust the rotational speed of the slow-speed upper pressure roller and the fast-speed upper pressure roller and the friction force on the flexographic paper tape.

[0025] Step G: Assemble the storage device; install the storage guide wheel on the lower right side of the segmented rapid lower roller, install the storage air vent below the segmented rapid lower roller, and install the storage basket on the right side of the segmented rapid lower roller.

[0026] A method for cutting face sheets into blocks, using an automatic face sheet cutting system, includes a cross-cutting device that intermittently processes transverse openings on a flexographic face sheet strip, a longitudinal cutting device located to the right of the cross-cutting device that continuously processes longitudinal openings on the flexographic face sheet strip, and a block-splitting device located to the right of the longitudinal cutting device that divides the flexographic face sheet strip into blocks of face sheets; a smart label is glued to the front of the block of face sheet, a temperature-sensitive ink is printed on the back of the block of face sheet, and a stamp is affixed to the surface of the block of face sheet.

[0027] Step 1: Pass the flexographic printing paper tape sequentially through the tension input guide roller, tension lower guide roller, tension upper guide roller, tension output guide roller, the gap between the stamp on the lower end of the N-shaped arm of the stamping machine and the lower U-shaped arm of the stamping adjustment screw, below the label coating machine, below the label rotary disc, above the ink roller, the gap between the upper and lower cross-cutting blades, the gap between the lower longitudinal cutting platform and the longitudinal rotary cutting blade, the gap between the slow lower damping roller and the slow upper pressure roller, the gap between the fast lower roller and the fast upper pressure roller, and above the storage guide roller; add ink to the stamping ink sponge; place the smart label in the label storage box;

[0029] Step 3: First, start the motor to drive the stamping output shaft.

The stamping upper stamp intermittently stamps both sides of the flexographic paper tape. After the stamping upper stamp leaves the flexographic paper tape, the stamping ink sponge uses capillary action to apply ink to the stamping ink brush. The stamping ink swing arm drives the stamping ink brush to rotate and apply ink to the stamping upper stamp.

[0030] Step four: First, the label output cylinder drives the label conical pusher plate to push the smart label along the label guide groove into the label conical guide opening located directly above; then, the label suction cup uses negative pressure to adsorb the smart label; second, the label rotating disk rotates 180 degrees and moves above the flexographic paper tape; third, the label gluing machine applies glue to the upper surface of the flexographic paper tape; immediately afterward, the label radial telescopic cylinder pushes the label suction cup to the gluing area, while the label suction cup applies positive pressure air to the smart label.

[0031] Simultaneously with step four, the ink roller rotates to apply the temperature-sensitive ink from the temperature-sensitive ink storage tank to the lower surface of the flexographic printing paper tape;

[0032] Step 5: The upper and lower cross-cutting shafts rotate, and the upper and lower cross-cutting blades intermittently make cross-cuts.

[0033] Step 6: Continuously cut the flexographic printing paper strip longitudinally with a rotary cutter;

[0034] Step 7: The slow-speed upper pressure roller of the segmentation is actively driven, and the slow-speed lower damping roller of the segmentation is driven; the fast-speed lower roller of the segmentation is driven, and the fast-speed upper pressure roller of the segmentation is actively driven, thus breaking the longitudinally cut flexographic paper strip into segmented paper.

[0035] Step 8: The storage guide wheel tilts the paper into the storage basket. After hitting the storage baffle, the paper is horizontally stacked and falls into the storage basket under the action of the storage air blower on the lower surface of the paper.

[0067] Step 1: Pass the flexographic printing paper tape 8 sequentially through the tension input guide wheel 11, tension downward guide wheel 14, tension upper guide wheel 17, tension output guide wheel 19, the gap between the stamp 26 at the lower end of the stamping upper n-shaped arm 24 and the stamping lower U-shaped arm 28 at the upper end of the stamping adjusting screw 27, below the label gluing machine 41, below the label rotating disk 32, above the ink roller brush 44, the gap between the cross-cutting upper cutter 46 and the cross-cutting lower cutter 48, the gap between the longitudinal cutting lower platform 49 and the longitudinal cutting rotary cutter 50, the gap between the segmented slow lower damping roller 51 and the segmented slow upper pressure roller 52, the gap between the segmented fast lower roller 53 and the segmented fast upper pressure roller 54, and above the storage guide wheel 55; add printing ink to the stamping ink sponge 30; place the smart label 36 in the label storage box 37;

[0068] Step two: First, adjust the tension of the lower tension spring 15 and the upper tension spring 18; adjust the rotation speed of the slow-speed upper pressure roller 52 and the fast-speed upper pressure roller 54 and the friction force on the flexographic printing paper strip 8; adjust the air force of the storage air outlet 58 and the position of the storage basket 56; then, start the paper tensioning device 1, the stamping device 2, the marking device 3, the cross-cutting device 4, the longitudinal cutting device 5, the segmentation device 6, and the storage device 7.

[0069] Step 3: First, start the motor to drive the stamping output shaft 21. The stamping output shaft 21 controls the stamping rectangular guide frame 23 through the stamping eccentric wheel 22, which drives the upper n-shaped arm 24 and the lower U-shaped arm 28 to move up and down intermittently along their respective stamping guide sleeves 25. The stamping stamp 26 intermittently stamps the flexographic paper tape 8 on both sides. When the stamping stamp 26 leaves the flexographic paper tape 8, the stamping ink sponge 30 uses capillary action to apply ink to the stamping ink brush 31. The stamping ink swing arm 29 drives the stamping ink brush 31 to rotate and apply ink to the stamping stamp 26.

[0070] Step four: First, the label output cylinder 38 drives the label conical pusher 39 to push the smart label 36 along the label guide groove 40 into the label conical guide opening 35 located directly above; then, the label suction cup 34 uses negative pressure to adsorb the smart label 36; next, the label rotating disk 32 rotates 180 degrees and moves above the flexographic paper tape 8; then, the label gluing machine 41 applies glue to the upper surface of the flexographic paper tape 8; immediately afterward, the label radial telescopic cylinder 33 pushes the label suction cup 34 to the gluing area, while the label suction cup 34 applies positive pressure air to the smart label 36.

[0071] Simultaneously with step four, the ink roller 44 rotates to apply the temperature-sensitive ink in the temperature-sensitive ink storage tank 43 to the lower surface of the flexographic printing paper tape 8.

[0072] Step 5: The upper cross-cutting shaft 45 and the lower cross-cutting shaft 47 rotate, and the upper cross-cutting blade 46 and the lower cross-cutting blade 48 perform intermittent cross-cutting.

[0073] Step 6: Continuously cut the flexographic paper strips 8 on 50 pairs of slitting rotary cutters;

[0074] Step 7: The slow-speed upper pressure roller 52 of the segmentation is actively driven, and the slow-speed lower damping roller 51 of the segmentation is driven; the fast lower roller 53 of the segmentation is driven, and the fast upper pressure roller 54 of the segmentation is actively driven, so as to break the longitudinally cut flexographic paper strip 8 into segmented paper strips 9.

[0075] Step 8: The storage guide wheel 55 tilts the sheet paper 9 into the storage basket 56. After the sheet paper 9 hits the storage baffle 57, it falls horizontally into the storage basket 56 under the action of the storage air blower 58 blowing horizontally on the lower surface of the sheet paper 9.

[0076] When using this invention, the flexographic printing paper strip 8 is processed into segmented paper sheets 9 through the paper tensioning device 1, stamping device 2, marking device 3, cross-cutting device 4, longitudinal-cutting device 5, segmenting device 6, and storage device 7, and multiple sheets are processed and cut simultaneously. The surface is marked, resulting in high precision, low scrap rate, and high efficiency. The tensioning lower guide wheel 14, tensioning lower spring 15, tensioning upper guide wheel 17, and tensioning upper spring 18 achieve automatic flexible tensioning, and the tensioning output guide wheel 19 achieves directional output. The stamping output shaft 21, stamping eccentric wheel 22, stamping rectangular guide frame 23, stamping upper N-shaped arm 24 / stamping lower U-shaped arm 28, and stamping upper stamp 26 achieve intermittent stamping, which is highly efficient. The stamping guide sleeve 25 provides guidance, and the stamping interval time is adjusted by the stamping adjustment screw 27. The stamping ink brush 31 uses capillary action to absorb ink from the stamping ink sponge 30 and applies ink to the stamp 26 on the stamp at regular intervals via the stamping ink swing arm 29.

[0077] The label rotating disk 32 rotates precisely, and the label radial telescopic cylinder 33 drives the label suction cup 34 to move radially, picking up or pushing out the smart label 36. The label conical guide port 35 facilitates automatic guidance and alignment. The label output cylinder 38, label conical push plate 39, label guide push groove 40, and smart label output are delivered to the adhesive area. The ink lifting frame 42 drives the ink roller brush 44 to brush ink at a fixed distance. Intermittent transverse pre-cutting is achieved through the transverse cutting upper rotating shaft 45, transverse cutting upper cutter 46, transverse cutting lower rotating shaft 47, and transverse cutting lower cutter 48. The longitudinal cutting lower platform 49 and longitudinal cutting rotary cutter 50 cut it into a strip structure. The segmented slow-speed lower damping wheel 51 achieves deceleration. By adjusting the pressure and speed of the segmented fast upper pressure wheel 54 to be greater than that of the segmented slow upper pressure wheel 52, the strip structure is truly cut into a sheet structure. The sheet paper is neatly stacked into the storage basket 56 through the storage inlet wheel 55, storage baffle 57, and storage air outlet 58.

[0078] This invention is reasonably designed, low in cost, sturdy and durable, safe and reliable, simple to operate, time-saving and labor-saving, cost-saving, compact in structure and easy to use.
