Detailed Description

The invention is described in detail below by way of exemplary embodiments. It should be understood, however, that elements, structures and features of one embodiment may be beneficially incorporated in other embodiments without further recitation.

In the description of the present invention, it is to be noted that: (1) the terms "inner", "outer", "upper", "lower", "front", "rear", and the like, indicate orientations or positional relationships based on positional relationships shown in the drawings, are merely for convenience in describing the present invention and simplifying the description, and do not indicate or imply that the referred devices or elements must have a specific orientation, be constructed and operated in a specific orientation, and thus, should not be construed as limiting the present invention; (2) when an element is referred to as being "fixed to" or "supported from" another element, it can be directly on the other element or intervening elements may also be present; (3) when an element is referred to as being "connected" to another element, it can be directly connected to the other element or intervening elements may also be present; (4) the terms "first," "second," and the like are used for descriptive purposes only and are not to be construed as indicating or implying relative importance.

An embodiment of the present invention provides a cutting device, where fig. 1 is a schematic perspective view of the cutting device, fig. 2 is a side view of the cutting device shown in fig. 1, and fig. 3 is a top view of the cutting device shown in fig. 1. As shown in fig. 1 to 3, the cutting device includes a cutter body 1, a workbench 2 and a cutter holder 3, the workbench 2 is disposed on the cutter holder 3, a first blade 11 is disposed on one side of the cutter body 1, a cutter groove 21 is disposed on the surface of the workbench 2, second blades 22 are disposed on two sides of the cutter groove 21, one end of the cutter body 1 is hinged to the workbench 2, and the other end of the cutter body 1 can rotate around the hinge so that the first blade 11 is closed into the cutter groove 21 for cutting.

The cutting device that above-mentioned embodiment provided sets up second cutting edge 22 through sword groove 21 both sides, cooperates with first cutting edge 11, realizes the smooth cutting of panel, especially to the novel WPC SPC floor that has added the EVA buffer layer, can avoid appearing the phenomenon that can't once only cut off, and the incision is neat, pleasing to the eye, and cutting efficiency is high.

Fig. 4 is a cross-sectional view taken along a direction a-a in fig. 3, and as shown in fig. 4, as a preferred embodiment, the table 2 includes two vertically opposite supporting portions 23, one side of the supporting portion 23 facing the cutter body 1 is provided with the second cutting edge 22, and the cutter groove 21 is formed between the two supporting portions 23. Optionally, referring further to fig. 4, the two supporting portions 23 are fixedly connected by a pin. It will be appreciated that the above is provided for only one specific embodiment of the table 2 and that other configurations are possible.

Referring to fig. 4, in order to smoothly discharge the material, the supporting portion 23 is bent, and the width between the two supporting portions 23 is gradually increased from the second blade 22 to the blade holder 3.

Preferably, the width of the knife groove 21 is 6mm to 7mm, i.e. the distance between the two supports 23 at the position of the second blade 22 is 6mm to 7 mm. If the width of the siping 21 is too small, the cutting is very laborious, and if the width is too large, the cutting effect is affected. The cutter groove with the width range is optimal for the cutting effect of the novel WPC/SPC floor.

In a preferred embodiment, the angle of the second cutting edge 22 is 30 ° to 50 °. The smaller the angle is, the sharper the cutting edge is, the better the cutting effect is, but the abrasion is relatively fast, and the service life is short; the larger the angle, the poorer the cutting effect, but the wear is relatively slow and the service life is long. The cutting edge within the angle range provided by the embodiment can ensure the cutting effect, and the service life of the cutting edge is not influenced as much as possible; most preferably, the angle of the second cutting edge 22 is 45 °.

As a preferred embodiment, as shown in fig. 1, a limit baffle 4 is arranged at one end of the surface of the workbench 2 far away from the hinge joint to limit the movement of the cut object along the direction of the knife groove 21. In the present embodiment, the object to be cut is a floor, and when cutting is performed, the floor slides toward the outside of the table along the tool slot direction by the force of the cutter body 1, thereby affecting the cutting process. The movement of the floor can be limited by arranging the limiting baffle 4, and the smooth operation of the cutting process is ensured.

As a preferred embodiment, as shown in fig. 5, a fixing portion 41 is disposed at the bottom of the position-limiting baffle 4, and the fixing portion 41 is inserted into the knife slot 21 and is fixedly connected to the workbench 2. The embodiment provides only one fixing mode of the limit baffle 4, and a person skilled in the art can select other fixing modes according to actual needs.

In a preferred embodiment, the fixed part 41 is connected to the table 2 by two or more pins. In this embodiment, when the width of the floor to be cut is large, and the floor cannot be fixed by the limit baffle 4, the pin for connecting the fixing part 41 and the workbench 2 can be detached, only one pin is left, and the limit baffle 4 is rotated by 180 degrees to be flush with the table top of the workbench 2, so that the limit effect of the limit baffle 4 is cancelled.

The above embodiment is only one way to achieve the cutting of floors of different sizes, and those skilled in the art can also adopt other ways to achieve the cutting. For example, the knife slot 21 can be lengthened, positioning holes can be arranged at different positions on two sides of the knife slot 21 at intervals, and the limiting baffle 4 can be fixed at a proper position according to different widths of the floor.

In a preferred embodiment, in order to facilitate the cutting of the floor, the partial blade of the first blade 11 is provided with saw teeth.

As a preferred embodiment, as shown in fig. 1, the end of the knife body 1 away from the hinge is provided with a rod 5 to apply force to the knife body 1. Optionally, the end of the shaft 5 is provided with a handle 51 to facilitate gripping and application of force.

The above description is only a preferred embodiment of the present invention, and not intended to limit the present invention in other forms, and any person skilled in the art may apply the above modifications or changes to the equivalent embodiments with equivalent changes, without departing from the technical spirit of the present invention, and any simple modification, equivalent change and change made to the above embodiments according to the technical spirit of the present invention still belong to the protection scope of the technical spirit of the present invention.
