Further, the tip of the blade 23 is located in the opening 25 of the groove 21, and the moving direction of the blade 23 is the same as the extension direction of the opening 25 of the groove 21. In this way, by movably connecting the cutting device 12 on the sliding rod 40 and placing the tip of the blade 23 in the opening 25 of the groove 21, the tool can be hidden while cutting large-size cardboard, thereby improving the safety of the cutting process and reducing the safety problems caused by the exposure of the blade 23.

[0062] Please continue to refer to Figures 1 to 4 The present application proposes a large-size cardboard cutting workbench 00, wherein the difference between the length of the right column 05 in the extension direction and the length of the left column 04 in the extension direction is greater than or equal to 30 mm.

[0063] Specifically, the large-size cardboard cutting workbench 00 includes a support frame 01, a table 07, a cutting device 12, and a limiting device 11. The table 07 is fixed on the side of the support frame 01 away from the ground, and the cutting device 12 and the limiting device 11 are located on the side of the table 07 away from the support frame 01. In an optional embodiment provided in the present application, along the direction perpendicular to the plane where the bottom frame 02 is located, the height of the left column 04 in the support frame 01 is lower than the height of the right column 05, so that the height of the left side 08 of the table 07 is lower than the height of the right side 10. Further, the difference between the length of the right column 05 in the extension direction and the length of the left column 04 in the extension direction is greater than or equal to 30 mm. Specifically, the difference between the length of the right column 05 in the extension direction and the length of the left column 04 in the extension direction can be: 30 mm, 31 mm, 32 mm, 33 mm, 34 mm, 35 mm, 36 mm, 37 mm, 38 mm, 39 mm, 40 mm, 41 mm, 42 mm, 43 mm, 44 mm, 45 mm, 46 mm, 47 mm, 48 mm, 49 mm, 50 mm, 51 mm, 52 mm, 53 mm, 54 mm, 55 mm, 56 mm, 57 mm, 58 mm, 59 mm, 60 mm, 61 mm, 62 mm, 63 mm, 64 mm, 65 mm, 66 mm, 67 mm, 68 mm, 69 mm, 70 mm, 71 mm, 72 mm, 73 mm, 74 mm, 75 mm, 76 mm, 77 mm, 78 mm, 7 7mm, 38mm, 39mm, 40mm, 45mm, 50mm, 55mm, 60mm, etc., are not listed here one by one. It is only necessary that the difference between the length of the right column 05 in the extension direction and the length of the left column 04 in the extension direction is greater than or equal to 30mm. When the difference between the length of the right column 05 in the extension direction and the length of the left column 04 in the extension direction is less than 30mm, the inclination angle of the table 07 is small, which may easily cause the cutting device 12 to automatically fall back insensitively or the sliding process to get stuck. In this way, by setting the height difference between the left column 04 and the right column 05 in the support frame 01, the left side 08 of the table 07 can be made lower than the right side 10, so that the operator can make the cutting device 12 automatically fall back to the side of the left stop block 19 along the slide bar 40 after completing the cutting without electric or manual operation, so as to facilitate the subsequent cutting work, reduce the operation process, and reduce manpower consumption.

[0064] Please continue to refer to Figures 1 to 4 The present application proposes a large-size cardboard cutting workbench 00, wherein the difference between the thickness of the right side 10 and the thickness of the left side 08 of the table 07 is greater than or equal to 30 mm.

[0065] The large-size cardboard cutting workbench 00 includes a support frame 01, a table 07, a cutting device 12, and a limiting device 11.

In an optional embodiment provided in the present application, along the direction perpendicular to the plane where the bottom frame 02 is located, the thickness of the left side 08 of the table 07 is lower than the thickness of the right side 10, that is, the height of the left side 08 of the table 07 is lower than the height of the right side 10. Further, the height difference between the right side 10 of the table 07 and the left side 08 is greater than or equal to 30 mm. Specifically, the height difference between the right side 10 of the table 07 and the left side 08 can be: 30 mm, 31 mm, 32 mm, 33 mm, 34 mm, 35 mm, 36 mm, 37mm, 38mm, 39mm, 40mm, 45mm, 50mm, 55mm, 60mm, etc. are not listed here one by one. It is only necessary that the thickness of the right side 10 of the table 07 is greater than or equal to 30mm than the thickness of the left side 08. When the difference between the thickness of the right side 10 of the table 07 and the thickness of the left side 08 is less than 30mm, the inclination angle of the table 07 is too small, which may cause the cutting device 12 to automatically fall back insensitively or the sliding process to get stuck. In this way, by setting the thickness difference between the left side 08 and the right side of the table 07, the left side 08 of the table 07 can be made lower than the right side 10. Further, after the operator completes the cutting, the cutting device 12 can automatically fall back to the side of the left stopper 19 along the slide bar 40 without electric or manual operation, which facilitates the subsequent cutting work, reduces the operating procedures, and reduces manpower consumption.

[0066] It should be noted that the thickness of the platform 07 increases gradually and evenly from the left side 08 to the right side 10 .

[0070] In summary, the large-size cardboard cutting workbench provided by the utility model achieves at least the following beneficial effects:

[0071] By designing the height difference between the left column and the right column or the thickness difference between the left side and the right side of the table, the cutting device can automatically fall back to the end with the lower horizontal edge height after cutting without electric or manual operation, which is convenient for subsequent cutting of cardboard and saves manpower and material resources; the limit strip can limit the cardboard to be cut and reduce the cardboard loss caused by the movement of the cardboard.

[0072] By arranging a left retaining edge on the left side plate of the table, sliding support can be provided for the limiting device while limiting the left side. The first positioning ruler arranged on the side of the left retaining edge facing the left stop block can accurately measure the size of the cardboard during the cutting process. The certain height of the base table can make the first positioning ruler and the cardboard not be in the same plane, thereby reducing the wear of the first positioning ruler during the measurement and cutting process. The specific structural design of the limiting device can flexibly adjust the positioning of the cardboard during the cutting process without blocking the first positioning ruler, which is convenient for the operator to observe. The handle is simple and easy to operate, will not cause the limit bar to shake, and improves the cutting accuracy.

[0073] By fixing the first positioning ruler on the left side of the table and fixing the second positioning ruler on the right side opposite to the first positioning ruler, when manually cutting large cardboard, the large-size cardboard can be abutted against the first positioning ruler and the second positioning ruler to achieve accurate positioning of the cutting, reduce cutting errors, and improve cutting accuracy.

[0074] By limiting the measuring lengths of the first positioning ruler and the second positioning ruler, the placement and measurement requirements of large cardboards of different cutting sizes can be adapted, thereby adapting to the packaging requirements of furniture of different sizes.

[0075] By fixing the groove on the outside of the horizontal edge of the table and making the groove flush with the table, there can be no height difference between the groove and the table, thereby reducing problems such as uneven cutting and cutting errors caused by the height difference between the table and the groove.

[0076] By movably connecting the cutting device on the slide bar and placing the tip of the blade in the opening of the groove, the cutter can be hidden while cutting large-sized cardboard, thereby improving the safety of the cutting process and reducing safety issues caused by the exposure of the blade.
