A cutting machine with an automatic sharpening mechanism

Abstract

The invention belongs to the technical field of cutting machines and discloses a cutting machine with an automatic knife grinding mechanism. The cutting machine comprises a rack, as well as a discharging mechanism and an automatic cutting mechanism which are sequentially arranged inside a rack from top to bottom, wherein the discharging mechanism is used for releasing materials; the automatic cutting mechanism is used for cutting the materials and comprises a driving component, a cutting component and a knife grinding component; the cutting component comprises a backing plate, a mounting base,a travelling cart and a cutter; and the knife grinding component comprises rotating plate fixing seats, rotating plates, knife grinding bar telescopic fixed rods and knife grinding bars. The cuttingmachine is provided with an elastic knife grinding mechanism, so that automatic knife grinding operation corresponding to the cutting machine is effectively realized; without detaching any component,the operation is simple; and the driving component of the cutter still performs knife grinding drive in the specific knife grinding process, so that installation and use of the knife grinding drivingcomponent are effectively avoided, and further the structure of the whole knife grinding mechanism is simpler.

Description

technical field [0001] The invention belongs to the technical field of cutting machines, and in particular relates to a cutting machine with an automatic sharpening mechanism. Background technique [0002] A cutting machine refers to a machine that uses a knife to perform a specified cutting operation on a material. Taking a cutting machine for flexible materials such as cloth and film as an example, the cutting knife rubs against the material during the cutting process, which causes the cutting knife itself to wear to a certain extent. Therefore, the cutting knife needs to be sharpened after working for a period of time; in view of the above problems, if manual sharpening is used, there will be operations such as stopping the machine to pick up the knife, sharpening the knife, and reinstalling, which is not only troublesome to operate, but also has sharpening efficiency. Low, and the problem that affects the working efficiency of the cutting machine itself; [0003] To sum...

[0002] A cutting machine refers to a machine that uses a knife to perform a specified cutting operation on a material. Taking a cutting machine for flexible materials such as cloth and film as an example, the cutting knife rubs against the material during the cutting process, which causes the cutting knife itself to wear to a certain extent. Therefore, the cutting knife needs to be sharpened after working for a period of time; in view of the above problems, if manual sharpening is used, there will be operations such as stopping the machine to pick up the knife, sharpening the knife, and reinstalling, which is not only troublesome to operate, but also has sharpening efficiency. Low, and the problem that affects the working efficiency of the cutting machine itself;

[0003] To sum up the current situation, people thought of installing an automatic sharpening mechanism on the cutting machine, but most of the automatic sharpening mechanisms proposed in the prior art have problems with relatively complicated structures, and an independent sharpening mechanism needs to be set during the sharpening process. Knife drive components, resulting in an increase in the production cost and use cost of the cutting machine;

[0004] In addition, due to the characteristics of flexible materials such as cloth and film, problems such as wrinkling and edge curling are prone to occur during the cutting process, which affects the cutting quality
