Soft material cutting knife

The invention relates to a soft material cutting knife, in particular to a tool which can optimize the edge cutting process of a soft material.

With the increasing development of the production and production of the civilian production industry, chemical and chemical soft materials such as protective films have been widely used, and this type of soft material film needs to be divided into independents by cutting before finalizing the process. The finished product, and the cutting method in the prior art mainly uses the soft material attached to a carrier board to make a downward vertical characterization on the surface thereof by using a cutting knife, and then forms a seam to allow the processing personnel to use the soft material. The finished product tears away, and such a conventional means actually has its missing points.

First of all, it is very difficult to control the force of the tool under the soft cutting force. Therefore, the surface of the bottom carrier plate may be damaged due to the large force applied. Over time, the carrier plate needs to be replaced, and at the same time, the tool and the bearing are required. Due to long-term contact between the plates, the tool may be worn or passivated. In addition, since the slits cut by the cutting tool cannot cause the edge to break, the subsequent removal of the soft material from the carrier plate may occur. The action is not easy, the difficulty is generated in the processing, or the slit which is cut by the cutting tool is too thin, so the problem of the subsequent process cannot be satisfied in the process, and so on, the inventor of the present invention thinks and designs A soft material cutting knife, with a view to improving the lack of existing technology, And promote the implementation and utilization of the industry.

In view of the above-mentioned problems, the main object of the present invention is to provide a soft material cutting knife having novelty, advancement and industrial utilization, etc., in order to overcome the difficulties of the prior art.

In order to achieve the above object, the technical means adopted by the present invention is to design a soft material cutting blade comprising: a connecting portion; a cutting blade portion correspondingly disposed at a front end of the connecting portion, the cutting blade portion having a a bottom portion, wherein the cutting blade portion is provided with at least all of the blade portions; and abutting portion corresponding to the front end of the bottom portion of the cutting blade portion, which is horizontally level with the object to be cut during the cutting operation Face up.

Wherein, the upper surface of the cutting blade portion is formed with an upper plane, and the cutting blade portion respectively forms two first inclined walls disposed obliquely downward from the two side edges of the upper plane, and the number of the cutting edge portions is two And respectively disposed at the front end edges of the outer wall surfaces of the two first inclined walls, and further, at the bottom side edges of the two first inclined walls, further forming two inclined second inclined walls toward the inner side, the two The second inclined walls are joined to form the bottom of the cutting blade.

Wherein, the soft material cutting blade further comprises a break corresponding to the concave portion from the front end of the upper plane of the cutting blade portion and being concavely formed toward the rear side; wherein the cross section of the broken portion is close to the shape And the two first inclined walls form a thin blade-shaped cutting structure; wherein the opening has a bottom wall, and a bottom edge is further disposed between the front edge of the bottom wall and the abutting portion Wherein the front edge of the bottom blade portion is further provided with at least one leading edge.

The soft material cutting knife of the present invention is designed to utilize a structural fit, and further produces a shovel-like cutting structure at the front end, and a flat abutting portion is provided at the bottom end of the cutting structure, so as to cut the soft material. In the process, it can be used as a contact buffer surface with the carrier plate, which can avoid damage to the carrier plate or the tool due to excessive force, so as to improve the service life thereof. In addition, the present invention has two first inclined wall designs on both sides. In addition, at the same time of cutting, the soft material after cutting can be slightly tilted upward due to the oblique component force, and the vacuum breaking effect is obtained to break away from the bonding with the carrier plate, which makes the subsequent operator easier. The tearing off of the self-supporting plate provides a high degree of convenience in practical applications, and in order to make the above-mentioned objects, technical features and gains after actual implementation more obvious, it will be better implemented below. The examples are accompanied by a corresponding schema for a more detailed description.
