Description

Technical Field

[0001] The utility model relates to a cutting device, in particular to a production and cutting device for automobile sound insulation cotton. Background Art

[0002] Sound insulation cotton has a good heat insulation effect. After being pasted inside the car hood, it can effectively prevent the high temperature of the engine from being directly transmitted to the hood, thereby protecting the paint on the surface of the hood, and at the same time avoiding the foggy hood affecting the vision on rainy days. On rainy days and in winter, due to the large temperature difference between the external temperature and the engine, coupled with the erosion of the hood by rain, the oxidation of the paint surface will be accelerated. Heat insulation cotton can protect the paint surface of the hood to a certain extent.

The cutting device for automobile sound insulation cotton production is set by setting a servo motor to start and drive the left and right adjustment screws to rotate, the left and right adjustment screws drive the threaded sleeve to move left and right, the left and right movement of the threaded sleeve drives the electric push rod at the bottom of the connecting rod to move left and right, and then the electric push rod is set to start and drive the pressure plate to move downward to press the sound insulation cotton, so that the sound insulation cotton can be fixed by adjusting the pressure plate movement at multiple angles, achieving the advantage of good fixing effect, thereby effectively solving the problem of poor fixing effect and serious reduction of product production quality during the cutting process of sound insulation cotton.

[0004] In the process of implementing the utility model, the inventors found that there are at least the following problems in this technology: after the device achieves the positioning purpose, it is necessary to cut the sound insulation cotton, but a fixed plate and a fixed rod are arranged above the moving structure of the device, which will interfere with the setting and operation of the subsequent cutting structure. Not only is the space for setting the cutting structure limited, but the cutting operation will also interfere with the moving operation, so that the cutting operation cannot be achieved after positioning is achieved.

According to the width of the sound insulation cotton, the angle of rotation of the servo motor 3 is controlled, thereby controlling the distance moved by the first moving block 5, so that the second moving frame 6 is located at the edge of the sound insulation cotton, which is convenient for positioning. When the position of the second moving frame 6 is determined, the second electric push rod 19 is started, so that the second moving frame 6 presses the edge of the sound insulation cotton. When cutting is required, the first electric push rod 8 is started at this time to drive the cutting blade 9 to move downward, and cooperate with the movement of the conveyor belt 11 on the sound insulation cotton to cut the sound insulation cotton.
