Description

Technical Field

[0001] The utility model belongs to the technical field of paper cutting equipment, and particularly relates to a printing paper cutting device. Background Art

[0002] Printing paper is commonly a kind of packaging printing paper printed with patterns, trademarks, words, etc. It generally includes kraft paper, moisture-proof paper, sandwich paper, white paper, label paper, etc. Packaging printing paper generally requires a relatively large thickness, a smooth and flat paper surface, and can withstand large temperature differences and humidity without wrinkling or damage. Existing printing paper generally needs to be cut into specified sizes or shapes during processing to facilitate the packaging of similar products. When cutting, workers need to unroll the paper roll and cut the paper.

[0003] When cutting paper, the two sides of the paper are prone to misalignment relative to the cutting tool, and the paper is prone to skew during the cutting process, affecting the cutting quality. Summary of the Utility Model

[0004] In view of the above deficiencies, the utility model provides a printing paper cutting device, which realizes the assistance for unrolling the printing paper roll by arranging a driving mechanism on the driving frame; lays the paper on the extension platform to ensure the dimensional accuracy of the cut paper and facilitate the measurement of the paper distance; and arranges flattening mechanisms on both sides of the cutting tool to prevent the paper from misaligning when cutting the paper, thereby improving the cutting quality of the paper.

[0005] The utility model is realized by the following technical solutions:

[0006] A printing paper cutting device includes a support assembly, an extension platform, and a cutting mechanism. The support assembly includes a paper roll frame and a driving frame. The printing paper roll is arranged on the paper roll frame. The driving frame includes a driving roller and a driving motor. The extension platform is provided with a flat surface for carrying the paper. The cutting mechanism is located between the support assembly and the extension platform. The cutting mechanism includes a cutting table, a cross beam track, and a cutter. A cutting hole is opened on the cutting table, and the extending direction of the cutting hole is the same as the extending direction of the printing paper roll. The cross beam track is fixedly arranged above the cutting hole. The cutter includes a sliding seat installed on the cross beam track, a first motor, a cutting tool, a tool cover, a second motor, and a flattening mechanism. The first motor can drive the sliding seat to move relative to the cross beam track. The cutting tool extends into the cutting hole, and the cutting tool is installed on the sliding seat through the tool cover. The second motor can drive the cutting tool to rotate. The flattening mechanism is installed on both sides of the tool cover and presses the paper to the cutting table to prevent the paper from misaligning when cutting the paper and improve the quality of the cut paper.

[0007] Further, the flattening mechanism includes a housing and a pressing wheel. The housing is fixed to the tool cover. The housing has a vertically downward opening, and the pressing wheel is located at the opening below the housing. By using the pressing wheel to squeeze the paper, the pressing wheel can move along with the sliding seat, facilitating the squeezing of the paper on both sides of the cutting tool, effectively preventing the paper from being misaligned, and improving the cutting quality of the paper.

[0008] Further, the flattening mechanism further includes a sliding groove, a bearing installed in the sliding groove, and a compression spring connecting the bearing and the sliding groove. The sliding groove is vertically arranged, the bearing can move vertically along the sliding groove, both ends of the pressing wheel are installed on the housing through the bearing, and the compression spring has a vertically downward pressing force on the pressing wheel through the bearing, realizing the elastic squeezing of the paper, which can not only play a role in squeezing the paper, but also enable the pressing wheel to roll along with the sliding seat.

[0009] Further, the housing of the bearing is square, and the bearing is slidably connected to the sliding groove.

[0010] Further, at least two flattening mechanisms are provided, and the flattening mechanisms are symmetrically distributed relative to the tool cover, improving the stability of the paper when the cutting tool cuts the paper.

[0011] Further, the cutting mechanism further includes a supporting roller located on one side of the cutting table close to the driving frame. The cutting table protrudes upward from the extension platform, reducing the resistance of the paper movement increased due to the setting of the cutting table.

[0012] Further, the two sides of the cutting table are provided with rounded corners to prevent the cutting table from scratching the paper.

[0013] Further, the surface of the cutting table is coated with a Teflon coating. The Teflon coating has a low coefficient of friction and good wear resistance, reducing the friction between the cutting table and the paper and facilitating the movement of the paper to the extension platform.

[0014] Further, the extension platform includes a supporting table, a slide rail, and a positioning baffle. The slide rails are fixed on both sides of the supporting table. The positioning baffle is installed between the two supporting tables and above the extension plane. The positioning baffle can slide relative to the supporting table along the extension direction of the slide rail. Scale lines are provided on the slide rail to realize the measurement of the dragging length of the paper, which helps to accurately cut the paper with a set length.

[0031] As Figures 1 to 6 shown, a printing paper cutting device includes a support assembly 1, an extension platform 2, and a cutting mechanism 3. The support assembly 1 includes a paper roller frame 11 and a drive frame 12. The printing paper roller 4 is mounted on the paper roller frame 11. The drive frame 12 includes a drive roller 121 and a drive motor 122. The extension platform 2 is provided with a flat surface 21 for carrying the paper 5. The cutting mechanism 3 is located between the support assembly 1 and the extension platform 2. The cutting mechanism 3 includes a cutting table 31, a cross beam track 32, and a cutter 33. A cutting hole 311 is formed in the cutting table 31. The extending direction of the cutting hole 311 is the same as the extending direction of the printing paper roller 4. The cross beam track 32 is fixedly provided above the cutting hole 311. The cutter 33 includes a sliding seat 331 mounted on the cross beam track 32, a first motor 332, a cutting tool 333, a tool cover 334, a second motor 335, and a flattening mechanism 34. The first motor 332 can drive the sliding seat 331 to move relative to the cross beam track 32. The cutting tool 333 extends into the cutting hole 311, and the cutting tool 333 is mounted on the sliding seat 331 through the tool cover 334. The second motor 335 can drive the cutting tool 333 to rotate. The flattening mechanism 34 is mounted on both sides of the tool cover 334 and presses the paper 5 against the cutting table 31 to prevent the paper 5 from being misaligned when cutting the paper 5 and improve the quality of cutting the paper 5.

[0032] In one embodiment, first, the printing paper roll 4 is mounted on the paper roll holder 11 of the support assembly 1, and then the end of the paper 5 is dragged around the driving roller 121. The driving motor 122 is started, and the driving motor 122 drives the driving roller 121 to rotate, thereby facilitating the separation of the paper 5 from the printing paper roll 4. Under the combined action of the driving motor 122 and manual dragging, the paper 5 is passed through the cutting mechanism 3. Then, the paper 5 is dragged to a set distance and laid on the flattening surface 21. The second motor 335 is started, and the second motor 335 drives the cutting tool 333 to rotate, so that the cutting tool 333 is in a high-speed rotation state. It should be noted that the cutting tool 333 partially extends into the cutting hole 311. Finally, the first motor 332 is started, and the first motor 332 drives the sliding seat 331 to move along the extension direction of the crossbeam track 32, so that the cutting tool 333 moves along the extension direction of the cutting hole 311, and the cutting tool 333 cuts the paper 5 laid on the cutting table 31.

[0033] During cutting, since the flattening mechanism 34 is installed on both sides of the tool cover 334, the flattening mechanism 34 squeezes the paper 5 on both sides of the cutting tool 333 to squeeze the paper 5 onto the surface of the cutting table 31. Since the paper 5 on both sides of the cutting tool 333 is squeezed, the cutting force of the cutting tool 333 on the paper 5 basically does not form a drag on the paper 5, thereby improving the cutting quality of the paper 5.

[0034] Preferably, the flattening mechanism 34 includes a housing 341 and a pressing wheel 342. The housing 341 is fixed to the tool cover 334. The housing 341 has a vertically downward opening, and the pressing wheel 342 is located at the opening below the housing 341. By using the pressing wheel 342 to squeeze the paper 5, the pressing wheel 342 can move along with the sliding seat 331, which is convenient for squeezing the paper 5 on both sides of the cutting tool 333, effectively preventing the paper 5 from being misaligned, and improving the cutting quality of the paper 5.

[0035] Preferably, the flattening mechanism 34 further includes a sliding groove 343, a bearing 344 installed in the sliding groove 343, and a compression spring 345 connecting the bearing 344 and the sliding groove 343. The sliding groove 343 is vertically arranged, the bearing 344 can move vertically along the sliding groove 343, both ends of the pressing wheel 342 are installed on the housing 341 through the bearing 344, and the compression spring 345 has a vertically downward pressing force on the pressing wheel 342 through the bearing 344, realizing elastic extrusion of the paper 5, which can not only play a role in squeezing the paper 5, but also enable the pressing wheel 342 to roll along with the sliding seat 331.

[0036] Preferably, the housing 341 of the bearing 344 is square, and the bearing 344 is slidably connected to the sliding groove 343.

[0037] In one embodiment, the pressing wheel 342 is embedded and installed at the bottom of the housing 341 and can move vertically along the housing 341. Specifically, both ends of the pressing wheel 342 are installed in the sliding grooves 343 on both sides of the housing 341 through square bearings 344, and a compression spring 345 that presses the bearing 344 is provided in the sliding groove 343, so that the pressing wheel 342 forms a pressing force on the paper 5. The bearing 344 is slidably installed in the sliding groove 343 and can slide vertically along the sliding groove 343. Since the housing 341 is fixed to the tool cover 334, when the sliding seat 331 drives the tool cover 334 to move, the pressing wheel 342 installed at the bottom of the housing 341 rotates, so that the pressing wheel 342 rolls relative to the paper 5. It should be noted that when the pressing wheel 342 rolls, it can still play a role in pressing the paper 5, but the pressing position on the paper 5 changes. Also, because the pressing wheel 342 is located on both sides of the tool cover 334, when the cutting tool 333 moves, the pressing wheel 342 is always located on both sides of the cutting tool 333, effectively improving the stability of the paper 5 on both sides of the cutting tool 333.

[0038] Preferably, at least two flattening mechanisms 34 are provided, and the flattening mechanisms 34 are symmetrically distributed relative to the tool cover 334 to improve the stability of the paper 5 when the cutting tool 333 cuts the paper 5.

[0039] Preferably, the cutting mechanism 3 further includes a support roller 35 located on the side of the cutting table 31 close to the driving frame 12. The cutting table 31 protrudes upward from the extension platform 2 to reduce the moving resistance of the paper 5 increased due to the setting of the cutting table 31.

[0040] In one embodiment, since the cutting table 31 protrudes from the extension platform 2, the paper 5 is likely to have a sliding friction with the cutting table at the cutting platform, increasing the moving resistance of the paper 5. By providing a support roller 35 on one side of the cutting table 31, a rolling friction occurs between the paper 5 and the support roller 35, which helps to reduce the frictional resistance between the paper 5 and the cutting table 31.

[0041] Preferably, the two sides of the cutting table 31 are provided with rounded corners to prevent the cutting table 31 from scratching the paper 5.

[0042] Preferably, the surface of the cutting table 31 is coated with a Teflon coating. The Teflon coating has a low coefficient of friction and good wear resistance, reducing the frictional force between the cutting table 31 and the paper 5 and facilitating the movement of the paper 5 to the extension platform 2.

[0043] Preferably, the extension platform 2 includes a support table 22, a slide rail 23, and a positioning baffle 24. The slide rail 23 is fixedly arranged on both sides of the support table. The positioning baffle 24 is installed between the two support tables and above the extension plane 21. The positioning baffle 24 can slide relative to the support table 22 along the extension direction of the slide rail 23. Scale lines are provided on the slide rail 23 to measure the dragging length of the paper 5, which helps to accurately cut the paper 5 with a set length.

[0044] In an embodiment, the positioning baffle 24 can be slid relative to the slide rail 23 to a set position in advance. When dragging the paper 5, it is only necessary to drag the paper 5 to the position of the positioning baffle 24 to determine the cutting distance of the paper 5. There is no need to measure the cutting length of each piece of paper 5 one by one, improving the cutting efficiency.

[0045] When adopting the above-mentioned printing paper cutting device, by setting a driving mechanism on the driving frame 12, the assistance for the unfolding of the printing paper roll 4 is realized; the paper 5 is laid on the extension platform 2 to ensure the dimensional accuracy of the cut paper 5 and facilitate the measurement of the distance of the paper 5; by arranging flattening mechanisms 34 on both sides of the cutting tool 333, the dislocation of the paper 5 during the cutting of the paper 5 is prevented, improving the cutting quality of the paper 5.

[0046] The above are only the embodiments of the present application and are not used to limit the present application. For those skilled in the art, various changes and modifications can be made to the present application. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included within the scope of the claims of the present application.
