However, in the actual production process, especially in the development and pilot stage of new casting equipment products, sheet-like film belts with different specifications are needed. In order to obtain different sized tape for sheet casting apparatus, the cutting is usually done manually. As a result, the cutting size precision is poor, the production efficiency is low, and when strip-shaped film strips of several meters, tens of meters, or even hundreds of meters smaller than the full width are required, the manual cutting mode for the casting equipment cannot be realized.

The principle of the basic scheme is as follows: the slurry is continuously supplied to the casting box by the slurry supply module, the casting box casts or coats the slurry on the base band to form a film band, and the film band is conveyed to a driving roller and a cutting roller of the cutting device through the conveying device. And in the conveying process of the film belt conveyed by the driving roller and the cutting roller, when the film belt needs to be cut, the combined cam is rotated. When the combined cam rotates, the jacking cam is abutted against the cutting rack, so that the cutting rack moves towards the driving roller. At the moment, the cutting cam in the combined cam is abutted against the cutting scissors, so that the cutting scissors cut the film belt.
The film belt is continuously conveyed to the cutting roller because the driving roller still continuously rotates in the cutting process, and the cutting roller moves a distance to the driving roller at the moment, so that the redundancy of the film belt exists between the driving roller and the cutting roller. The redundant film strips may be folded, and when the cutting machine frame returns to the original position, the folded film strips are continuously transmitted to the cutting roller and are extruded by the cutting roller, and finally the folding of the finished film strips is caused. In the device, when the cutting frame moves to the driving roller, the piston and the cylinder body relatively move, and pressure gas is generated in the cylinder body. Pressure gas in the cylinder body blows to the membrane strip through the air guide pipe, so that redundant membrane strips are tensioned, and the folding of the redundant membrane strips is avoided.
The beneficial effect of this basic scheme lies in:
1. this device can cut through machinery, and it is low to have avoided the manual work to cut the productivity that causes, can't cut the condition in longer membrane area.
2. This device is through the removal that cuts the frame, makes the inside pressure gas that produces of cylinder body blow to redundant membrane area and make it expand, has avoided the folding of redundant membrane area, leads to the defect of finished product membrane area.
3. The device is characterized in that the cutting device is arranged behind the driving roller, so that when the cutting device cuts the film strip, the normal conveying of the film strip before the driving roller is not influenced.
4. The device enables the cutting machine frame to move towards the driving roller when the film strip is cut, so that redundant films are arranged between the driving roller and the cutting roller, the film strip is prevented from being pulled when the film strip is cut to influence the transmission of the film strip before the driving roller, and the influence of the cutting on the operation of the whole equipment is minimized.
The first optimization scheme is as follows: the cutting machine is characterized in that a vertical sliding groove is formed in the cutting machine frame, two ends of the cutting roller are connected in the vertical sliding groove in a sliding mode, and a lifting wedge block used for lifting the cutting roller is fixed between the cutting roller and the driving roller. When the cutting frame moves towards the driving roller, the cutting roller moves to the inclined plane of the lifting wedge block along with the driving roller, so that the cutting roller is separated from the film belt. Thereby when making the membrane area cut, the film area is not crowded to the cutting roll, avoids the membrane area to receive the pulling force of cutting the roller when cutting, and then prevents that the membrane area from receiving in the same direction as.
And the second optimization scheme is as follows: the cylinder body is fixed with an anti-falling wheel for preventing the membrane belt from falling off the ground. The redundant membrane strip is hung by the anti-drop wheel, and the redundant membrane strip is prevented from dropping to the ground when being too long.
And the optimization scheme is three: the far end profile of the jacking cam is arc-shaped. When the far-end profile abuts against the cutting machine frame, the machine frame does not move towards the driving roller any more when the cam rotates during the arc-shaped far-end profile, so that the film belt is kept static during cutting, and the film belt is further prevented from being pulled and damaged when being cut.
And the optimization scheme is four: cut and cut including last scissors and lower scissors, go up and cut respectively first gear of fixedly connected with and second gear with lower scissors, first gear and second gear meshing, first gear and second gear rotate to be connected in cutting the frame, and the torsional spring that resets is installed with the rotation junction that cuts the frame to first gear. The setting up of first gear and second gear makes cut on or cut down and receive the cam conflict messenger that cuts, and cut on and cut down can synchronous motion, the unilateral power that utilizes the cam to provide in the adaptation this device.
