Description

Technical Field

[0001] The present application relates to the technical field of cardboard processing, and in particular to a cardboard cutting structure. Background Art

[0002] During the initial processing of cardboard, although the main structure of the cardboard is basically formed, its edges often fail to achieve the desired smoothness and refinement, which directly affects the overall quality of the product. Therefore, to ensure the final quality of the cardboard product, its edges must be further refined through a professional cutting process.

[0003] At the forefront of relevant technological exploration, patented invention CN118219128B proposes an innovative automatic square plate grinding machine, featuring a highly automated and intelligent design. It integrates transverse and longitudinal conveying components and a reversing assembly, efficiently completing the automated transport and direction change of cardboard. Furthermore, the machine cleverly incorporates cutting assemblies on both sides of the transverse and longitudinal conveying assemblies. Leveraging the precise coordination of the tensioning wheel and cutting belt, coupled with the powerful drive source, the machine achieves precise cutting of the cardboard edges.

[0004] However, while this cutting mechanism demonstrated high efficiency and precision in cutting cardboard edges, its technical limitations gradually became apparent during practical application. In particular, after the initial cut of the cutting strip, debris and impurities often remain along the cardboard edges. This residue not only detracts from the product's aesthetics but can also interfere with subsequent processing. Currently, additional workers are required to manually clean these residues, which undoubtedly increases labor costs and reduces production efficiency, leaving room for improvement. Utility Model Content

[0008] By adopting the above technical solution, during the cardboard processing, the cardboard is placed on the cutting table in advance and slides through the conveying assembly. The two edges of the cardboard are cut when passing through the cutting assembly, and then the cleaning cotton on the fixed block is used to clean the edges of the cardboard just cut, and the debris on the edges of the cardboard is wiped away; thereby simplifying the cleaning process of the cardboard edge debris and improving the overall cardboard processing efficiency.

[0009] Optionally, a positioning plug is fixedly provided on the bottom side of the fixing block, and a positioning slot for the positioning plug to be inserted and fixed is provided on the slide rail.

[0010] By adopting the above technical solution, due to the matching arrangement of the positioning insert and the positioning slot, during the installation of the fixing block, the positioning insert on the fixing block is inserted into the positioning slot, thereby facilitating the installation and removal of the fixing block.

[0011] Optionally, an elastic clamping piece is provided on the outer surface of the positioning plug block, and a positioning groove for inserting the elastic clamping piece is provided on the inner wall of the positioning slot.

[0012] By adopting the above technical solution, when the positioning block is inserted into the positioning slot, the elastic clip on the positioning block is inserted into the positioning groove in the positioning slot, thereby improving the installation stability of the positioning block in the positioning slot.

[0013] Optionally, a fixing notch for inserting cleaning cotton is provided on the fixing block, and a locking screw hole connected to the fixing notch is provided on the side of the fixing block; a locking bolt is provided above the cutting table; the locking bolt is screwed into and passes through the locking screw hole, and then tightened against the cleaning cotton inside the fixing notch.

[0014] By adopting the above technical solution, when installing the cleaning cotton, due to the setting of the fixing notch and the locking bolt, the staff will place the cleaning cotton into the fixing notch in advance, and then screw the locking bolt into and through the locking screw hole, so that the end of the locking bolt is tightly pressed against the cleaning cotton inside the fixing notch; it is convenient for fixing the cleaning cotton and replacing it later.

[0015] Optionally, the locking bolt is a butterfly bolt.

[0016] By adopting the above technical solution, since the locking bolt is a butterfly bolt, the user can directly manually rotate the locking bolt.

[0017] Optionally, a guiding slope is provided on the opening edge of the fixing notch.

[0018] By adopting the above technical solution, it is convenient to insert the cleaning cotton into the interior of the fixed notch along the guiding slope, thereby facilitating the installation of the cleaning cotton.

[0019] Optionally, the conveying assembly comprises a plurality of guide wheels rotatably arranged on the slide rail, and a driving member fixed on the slide rail to drive the guide wheels to rotate, and the outer circumferential surface of the guide wheels is provided with a guide ring groove for the paperboard edge to be inserted.

[0020] By using the above technical scheme, in the paperboard conveying process, the opposite edges of the paperboard are respectively clamped into the guide ring grooves on the opposite guide wheels, and then the driving member is started to drive the guide wheels to rotate, and the guide wheels will drive the paperboard to slide when rotating, thereby realizing automatic transportation of the paperboard.

[0021] Optionally, a support frame is fixed on one side of the cutting table, the cutting assembly comprises two tensioning wheels rotatably arranged on the support frame, and a power member fixed on the support frame to drive the tensioning wheels to rotate, and the outer circumferences of the two tensioning wheels are jointly provided with a cutting belt.

[0022] By using the above technical scheme, when the cutting assembly grinds and cuts the edges of the paperboard, the power member drives the tensioning wheels to rotate, and then the cutting belt rotates, and the edges of the paperboard are ground by the high-speed rotating cutting belt. Since it is soft cutting, the vibration and noise generated are small, and the influence on the working environment during processing is reduced.

[0023] In summary, the present application includes at least one of the following beneficial technical effects:

[0024] 1. In the processing of paperboard, the paperboard is placed on the cutting table in advance and slides through the conveying assembly, and the edges of the paperboard are cut and processed when passing through the cutting assembly, and then the cleaning cotton on the fixing block is used to clean the edges of the paperboard after cutting, and the debris on the edges of the paperboard is wiped and cleaned. This simplifies the cleaning process of the paperboard edge debris and improves the overall processing efficiency of the paperboard. BRIEF DESCRIPTION OF DRAWINGS
