on the other hand, when the cutting blade 6 is positioned at one side close to the fixed support 10, one end of the driving slider 12, which is provided with the trigger inclined plane 40, is positioned in the limiting U-shaped shell 11, and the slider 26 mounted on the driving slider 12 is in contact with the tail end of the sliding groove 39 formed in the limiting U-shaped shell 11, so that the limiting U-shaped shell 11 mounted on the limiting U-shaped shell 11 is driven to move while the driving slider 12 moves relative to the compression bar 1, and in the moving process of the limiting U-shaped shell 11, when one end, which is close to the fixed support 10, of the limiting U-shaped shell 11 is separated from the knocking plate 4, the limiting U-shaped shell 11 loses the support limitation on the knocking plate 4, and at this time, the knocking plate 4 swings downwards under the action of the second plate spring 15, the knocking plate 4 swings downwards to drive the swinging plate 20 mounted on the limiting U-shaped shell, and the swinging plate 20; in an initial state, the swinging plate is in an inclined state in the knocking plate under the action of the first plate spring, namely, two knocking blocks arranged on the swinging plate are distributed in the knocking plate in a vertically staggered manner, so that the knocking block 13 arranged on the knocking plate 4 and close to one end of the first plate spring is preferentially contacted with a ceramic tile in the downward swinging process, after the knocking block 13 is contacted with the ceramic tile, the ceramic tile reversely applies an upward reaction force to the knocking block 13, so that the knocking block 13 reversely swings upwards, the reverse swinging of the knocking block 13 drives the other knocking block 13 to swing downwards through the swinging plate 20, when the two knocking blocks 13 are completely contacted with the ceramic tile in the swinging process, the two knocking blocks 13 jointly press the ceramic tile downwards, and because the side, which is not knocked, of the ceramic tile is pressed by hand, the ceramic tile is separated from two ends of the cutting line after the side, which is not pressed by hand, is knocked, namely the ceramic tile is cut; after the ceramic tile is cut, the pressing rod 1 is lifted upwards, when the pressing rod 1 is lifted upwards, the pressing rod 1 can drive the knocking plate 4 and the driving slider 12 to swing upwards, the driving slider 12 swings upwards to drive the cutting blade 6 to swing upwards, when the cutting blade 6 swings upwards and loses resistance, the driving slider 12 slides towards one side close to the fixed support 10 under the action of the reset spring 3, the driving slider 12 slides to drive the first gear 31 installed on the inner side to move relative to the pressing rod 1, the third rotating shaft 38 rotates reversely through the transmission of the rack 30, the second gear 32, the third gear 33, the fourth gear 34 and the fifth gear 36 when the first gear 31 moves upwards, the mounting frame 23 swings to drive the cutting blade 6 to swing and reset; when the driving slider 12 moves in a resetting way, the driving slider can drive the limiting U-shaped shell to reset together, but because the slider 26 arranged on the driving slider 12 is not contacted with the front end of the sliding chute 39 formed on the limiting U-shaped shell 11 at the beginning, when the driving slider and the limiting U-shaped shell move in a resetting way, after the upper end of the limiting U-shaped shell is contacted with the knocking plate, the driving slider 12 can move relative to the limiting U-shaped shell 11, when the driving slider 12 starts to move relative to the limiting U-shaped shell 11, the end of the driving slider 12 with the triggering inclined surface 40 can firstly slide out of the limiting U-shaped shell 11, then the end of the adjusting slider with the triggering inclined surface is contacted with the lower side surface of the end of the knocking plate 4 far away from the fixed bracket 10, the driving slider 12 can press the knocking plate 4 to make the knocking plate 4 swing upwards under the action of the triggering inclined surface 40, the driving slider 12 moves to the lower side of the knocking plate 4, when the slide block 26 installed on the driving slide block 12 contacts the front end of the slide slot 39 opened on the limiting U-shaped shell 11, the driving slide block 12 drives the limiting U-shaped shell 11 to move, as shown in fig. 11, the same end of the limiting U-shaped shell and the inclined plane of the driving slide block is also provided with a U-shaped shell inclined plane 43, and when the inclined plane on the limiting U-shaped shell contacts the knocking plate, the limiting U-shaped shell moves to the lower side of the knocking plate 4 under the pulling of the driving slide block and the cooperation of the inclined plane on the limiting U-shaped shell; the two knocking blocks 13 arranged on the knocking plate 4 can reset under the action of the first plate spring 14; the second plate spring 15 is forced to prepare for the next time during the swinging up of the striking plate 4, and finally the driving slider 12, the cutting blade 6, and the restraining U-shaped housing 11 are all reset to the initial state.
In summary, the following steps:
in the cutting process of the traditional cutting machine, firstly, the cutting knife needs to be pulled to slide on a specified cutting line on a ceramic tile once, and then, two sides of the cutting line are manually pressed downwards to separate the ceramic tile from two ends of the cutting line; in the cutting machine designed by the invention, only the pressing rod 1 needs to be pressed downwards in the use process, so that the pressing rod 1 drives the cutting blade 6 to swing downwards, the cutting blade 6 is driven to swing reversely by the ceramic tile, the driving slider for installing the cutting blade 6 is triggered by the swinging of the cutting blade 6 to slide on the pressing rod 1, the driving slider 12 slides to drive the cutting blade 6 to slide relative to the ceramic tile, the ceramic tile is cut, after the cutting is finished, the knocking plate 4 installed on the pressing rod 1 can be triggered to knock the ceramic tile downwards, so that the ceramic tile is separated from two ends of the cutting line, and the ceramic tile is cut off, and the cutting machine is convenient and; according to the cutting machine, the compression amount of the return spring 3 is increased continuously while the pressure rod 1 swings downwards, and the pressure of the return spring 3 is increased continuously; the angle between the pressure rod 1 and the mounting frame 23 is continuously increased along with the downward swinging of the pressure rod 1, the moment arm of the cutting blade 6 under the pressure of the return spring 3 is continuously reduced, namely the moment arm of the return spring 3 under the pressure of the return spring 3 is reduced while the pressure of the return spring 3 is increased, the moment arm and the moment arm are combined, the cutting force applied to the cutting blade 6 by the return spring 3 can keep a basically stable state, namely the cutting stability of the cutting machine on the ceramic tile is relatively good; according to the cutting machine designed by the invention, the cutting force of the cutting blade 6 in the cutting machine on the ceramic tile can be adjusted by adjusting the elastic strength of the return spring 3, namely, the cutting machine can adapt to different types of ceramic tiles by replacing the return springs 3 with different strengths.
