Description

Technical Field

[0001] This utility model relates to the field of grooving knife technology, specifically a grooving knife for cardboard box processing. Background Technology

[0002] Cardboard box slotting knives are used to slot cardboard boxes. Common slotting knives usually have a serrated structure for cutting the cardboard. However, the serrated structure has a slow cutting speed and is prone to wear and damage, which is not conducive to long-term use.

[0003] Cutting can also be done with a blade. If the cutting force is too small, it will not be able to cut; if the cutting force is too large, it may cause the cardboard to deform, or even more seriously, the blade may be damaged by a collision. Utility Model Content

[0004] The purpose of this invention is to provide a grooving knife for cardboard box processing, which solves the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a grooving knife for cardboard box processing, comprising a mounting frame and a plurality of cutting heads, wherein the mounting frame is provided with a plurality of skeleton grooves, the cutting heads are installed in the skeleton grooves, and the cutting heads can slide back and forth in the skeleton grooves along the cutting direction of the blade, and metal springs are also installed in the skeleton grooves, the metal springs respectively abutting against the inner end of the cutting head and the bottom surface of the skeleton groove.

[0006] Preferably, several of the cutting heads are symmetrically arranged on opposite sides of the mounting frame, with the cutting heads on the same side forming a crescent shape.

[0007] Preferably, the mounting frame is square-shaped and has a longitudinal through slot.

[0008] Preferably, the cutter head is provided with a guide portion, and the mounting frame is provided with a guide groove that matches the guide portion.

[0009] Preferably, the mounting frame is covered with a cover on its side, and the cover covers several skeleton grooves.

[0010] Preferably, the cover is provided with a guide groove 2 that is adapted to the guide portion.

[0011] Preferably, the metal spring is in the shape of a wavy line.

[0012] Preferably, the mounting frame is further provided with a gripping opening.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0014] This invention features a blade and a metal spring. When the blade is cutting, the metal spring can counteract excess punching force and prevent the cardboard from deforming. If the punching force is too small, the elasticity of the metal spring can be converted into punching force, ensuring successful slotting and punching of the cardboard. Attached Figure Description

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] In the description of this utility model, it should be understood that the terms "center," "longitudinal," "lateral," "upper," "lower," "front," "rear," "left," "right," "horizontal," "vertical," "top," "inner," and "outer," etc., indicating the orientation or positional relationship, are based on the orientation or positional relationship shown in the accompanying drawings and are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model. Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0020] Please see Figures 1 to 3This utility model provides an embodiment of a grooving knife for cardboard box processing, comprising a mounting frame 1 and a plurality of blade heads 2. The mounting frame 1 is provided with a plurality of skeleton grooves 3, and the blade heads 2 are installed in the skeleton grooves 3, and the blade heads 2 can slide back and forth in the skeleton grooves 3 along the cutting direction of the blade. Metal springs 4 are also installed in the skeleton grooves 3, and the metal springs 4 abut against the inner end of the blade head 2 and the bottom surface of the skeleton groove 3 respectively. At the same time, a cover 5 is installed on the outside of the mounting frame 1, which can cover the plurality of skeleton grooves 3, so that the blade heads 3 and the metal springs 4 are installed in the skeleton grooves 3. During punching, the metal springs 4 can offset excess punching force to prevent cardboard deformation. If the punching force is too small, the elasticity of the metal springs 4 can be converted into punching force to ensure successful grooving and punching of the cardboard, while ensuring cutting efficiency.

[0021] Furthermore, several blades 2 are symmetrically arranged on opposite sides of the mounting frame 1. Several blades 2 on the same side are crescent-shaped, forming two crescent-shaped blade structures, which can improve cutting efficiency.

[0022] In this embodiment, the mounting frame 1 is square in shape and has a longitudinal through groove 6, through which the cut waste material can be discharged.

[0023] In this embodiment, the cutter head 2 is provided with a guide part 7, the mounting frame 1 is provided with a guide groove 8 that matches the guide part 7, and the cover 5 is provided with a guide groove 9 that matches the guide part 7. The two guide parts 7 are respectively inserted into the corresponding guide groove 8 and guide groove 9, and the guide parts 7 can slide along the corresponding guide groove 8 or guide groove 9. This structure can improve the accuracy direction of the cutter head 2 during stamping, and at the same time limit the cutter head 2 to prevent the cutter head 2 from dislodging from the skeleton groove 3.

[0024] In this embodiment, the metal spring 4 is in the shape of a wavy line; the above is one embodiment and does not limit the metal spring 4 to other shapes.

[0025] Furthermore, the mounting frame 1 is also provided with a grip opening 10, which makes it convenient for users to operate by hand and allows for manual cutting of the cardboard box, thus increasing the implementation method of the grooving knife.

[0026] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
