Description

TECHNICAL FIELD

[0001] The present application relates to a box cutting machine. BACKGROUND

[0002] The box cutting machine (also called box cutting machine or box cutting machine) is a cutting equipment for paperboard, corrugated paperboard, plastic board and other materials, widely used in packaging industry, especially for designing new cartons, paper boxes and other paper packaging products. It can accurately cut according to the set size to ensure that the die-cut paperboard is consistent with the size of the designed paper packaging box.

[0003] The box cutting machine usually has a cutting table and a cutting head that can move freely along the cutting table. The cutting head carries a cutting knife and is precisely controlled and quickly moved to cut the paperboard with the cutting knife. The paper is fixed on the cutting table through small air suction holes on the cutting table. In the existing cutting process, the cutting knife needs to be continuously fed downward and retracted upward. During the retraction process, the cutting knife is easy to move upward with the paperboard, although the moving distance is small, but it will directly affect the smoothness of the cutting line, and it is also easy to affect the cutting accuracy of the next knife. In addition, during the cutting process, the blade will extrude and rub the edge of the paper at the cutting position. Due to the limited adsorption force of the air suction hole on the local paper, it is easy to cause deformation and damage of the paper. CONTENT OF THE UTILITY MODEL

[0004] In order to solve the above technical problems, the purpose of the present application is to provide a box cutting machine with high cutting precision and smooth cutting line.

[0005] In order to achieve the above purpose, the utility model provides a box cutting machine, which comprises a workbench with air suction hole soft pad and a cutting head assembly, the workbench has a work surface capable of adsorbing the paper blank to be cut and extending along the XY plane, the cutting head assembly comprises a cutting head and a sliding drive mechanism for driving the cutting head to slide along the X axis and the Y axis respectively, the cutting head comprises a tool holder, a cutting blade capable of being detachably clamped in the middle of the tool holder and having a cutting tip, a lifting drive motor for driving the tool holder to move along the Z axis direction, and a rotary drive motor for driving the tool holder to rotate around the rotary shaft extending along the Z axis direction, the cutting head further comprises a sponge component, and the cutting tip is located on the upper side of the lower end of the sponge component.

[0006] In a possible implementation, the cutting tip is 1-3mm away from the lower end of the sponge component.

[0007] In a possible implementation, the sliding drive mechanism is a gantry mechanism.

[0008] In a possible implementation, the cutting head further comprises a ring sleeve coupled to the outside of the knife holder, and the sponge component is located inside the ring sleeve and coupled to the inner wall of the ring sleeve and / or the outer surface of the knife holder.

[0009] In a possible implementation, the sponge component is bonded to the inner wall of the ring sleeve and / or the outer surface of the knife holder.

[0010] In a possible implementation, the middle part of the knife holder is provided with a mounting groove for mounting the cutting blade, and the knife holder is further provided with a locking screw hole penetrating the inside and outside and intersecting with the mounting groove, and the cutting blade can be locked on the knife holder by a locking screw passing through the locking screw hole.

[0011] In a possible implementation, the ring sleeve is provided with a through hole for the locking screw to pass through.

[0012] In a possible implementation, the ring sleeve is provided with a plurality of screw holes arranged circumferentially, and the ring sleeve is abutted against the outer wall of the knife holder by a plurality of abutting screws arranged in the plurality of screw holes.

[0013] In a possible implementation, the sponge component comprises two sponge bodies arranged oppositely, and the cutting blade is located between the two sponge bodies.

[0014] In a possible implementation, a gap of 1-2 mm is left between the cutting blade and the sponge component.

[0015] The box-type cutting machine provided in the application comprises a cutting head, a cutting blade and a sponge component. The sponge component is arranged around the cutting tip of the cutting blade and the lower end of the sponge component is lower than the cutting tip. When the cutting blade cuts downward, the sponge component generates a downward elastic force to fix the paper cutting edge on the cutting pad. When the cutting blade retreats upward, the sponge gradually recovers. Since the cutting tip is located above the lower end of the sponge component, the sponge always has a downward elastic force to keep the paper on the workbench before the cutting blade and the paper separate, thereby ensuring the smoothness of the cutting line. Moreover, since the paper always remains in the original position, better cutting precision can be obtained after cutting. BRIEF DESCRIPTION OF DRAWINGS

However, it will be appreciated that various exemplary embodiments can be practiced without these specific details, or in an implementation that is not one of the specific embodiments. In other instances, well-known structures and functions are not described in detail in order to avoid obscuring the application. Also, various exemplary embodiments can be different but not necessarily mutually exclusive. For example, the specific shape, structure, and characteristics of an exemplary embodiment can be used or implemented in another exemplary embodiment without departing from the concept of the present application.

[0024] Referring to Figure 1 which illustrates an example of a box-type cutting machine 100. The box-type cutting machine 100 includes a worktable 1 and a cutting head assembly 2. The worktable 1 is provided with air suction hole soft pads and has a work surface 11 capable of supporting a paper blank to be cut, which extends along the XY plane.

The cutting head 21 includes a blade holder 211, a cutting blade 212 detachably clamped in the middle of the blade holder 211 and having a cutting tip 2121, a lifting drive motor 213 that drives the blade holder 211 to move along the Z-axis, and a rotary drive motor 214 that drives the blade holder 211 to rotate together about a rotation axis L1 extending along the Z-axis.

[0026] In this example, the tool holder 211 is fixed at the lower end of the upright 210 extending along the axial direction, and the upright 210 is simultaneously connected to the lifting drive motor 213 and the rotation drive motor 214.

[0027] The cutting head 21 also includes a sponge component 215, and the cutting tip 2121 of the cutting blade 212 is located above the lower end portion 2151 of the sponge component 215. In some embodiments, the distance D1 between the cutting tip 2121 and the lower end portion 2151 of the sponge component 215 is 1-3 mm.

[0028] The cutting head 21 also includes a ring sleeve 216. The ring sleeve 216 is fitted onto the outside of the cutter holder 211. The ring sleeve 216 is configured to position the sponge component 215.
