[0023] The bidirectional lead screw 4 and the right end of the hexagonal prism 8 are fixedly connected with a plurality of clamping columns 9 evenly distributed along the circumferential direction thereof; the right end of the lifting frame 3 on the right side is fixedly connected with a hinged frame 10 located between the bidirectional lead screw 4 and the hexagonal prism 8; a swing rod 11 is hinged at the right end of the hinged frame 10; the bidirectional lead screw 4 and the right end of the hexagonal prism 8 are slidably connected with a T-shaped connecting rod 12; a waist-shaped groove is provided on the left side of the connecting rod 12; the upper and lower sides of the swing rod 11 can be respectively inserted into the waist-shaped grooves on the corresponding sides; the outer wall of the connecting rod 12 is coaxially provided with a rotatable one; a plurality of insertion rods 14 evenly distributed along the circumferential direction thereof are fixedly connected at the left end; the insertion rod 14 can be inserted into the gap between the two clamping columns 9 on the corresponding sides.

[0024] like Figures 5 to 7 As shown, the clamping column 9, the articulated frame 10, the swing arm 11, the connecting rod 12, the spur gear 13 and the insertion rod 14 are arranged. The swing arm 11 can be used to drive the connecting rod 12 to move left and right, and at the same time drive the spur gear 13 on the corresponding side to move left and right. Then, when the insertion rod 14 on the spur gear 13 is inserted into the gap between the clamping column 9 on the corresponding side, the spur gear 13 can drive the corresponding bidirectional screw 4 or hexagonal prism 8 to rotate, thereby ensuring that the two will not rotate at the same time, that is, the width cannot be adjusted during cutting, and the cutting knife 7 does not rotate when the width is adjusted, which can ensure the safety of the device and avoid the cutting knife 7 rotating during adjustment and causing collision with other objects to cause losses or safety accidents.

[0025] The right end of the lifting frame 3 on the right side is rotatably connected to two upper and lower opposite rotating shafts 15, and the two rotating shafts 15 are connected through a toothed belt 16. The upper and lower ends of the front side of the toothed belt 16 are respectively engaged with the corresponding sides thereof. The right end of the lifting frame 3 on the right side is fixedly connected to a protective shell 17, and the right end of the protective shell 17 is fixedly connected to a rotating motor 18 coaxial with the rotating shaft 15 on the lower side, and the output end of the rotating motor 18 is fixedly connected to the rotating shaft 15 on the lower side.

[0026] like Figures 3 to 5As shown, a rotating shaft 15, a toothed belt 16 and a rotating motor 18 are provided. The rotating motor 18 can be used to drive the rotating shaft 15 to rotate, and then the toothed belt 16 can be used to drive the two spur gears 13 to rotate, ensuring that the spur gears 13 can rotate synchronously, thereby reducing the setting of the power source.

[0027] The opposite ends of the two moving frames 5 are respectively rotatably connected with bevel gears 19, the outer wall of the moving frame 5 is rotatably connected with a telescopic rod 20, the lower side of the telescopic rod 20 is rotatably connected with the cutting frame 6 on its corresponding side, the upper and lower ends of the telescopic rod 20 are respectively fixedly connected with bevel gears 21, the upper bevel gear 21 is meshed with the bevel gear 19 on its corresponding side, and the opposite ends of the two cutting knives 7 are respectively coaxially fixedly connected with helical gears 22, and the helical gear 22 is meshed with the bevel gear 21 on its corresponding side.

[0028] like Figure 6 As shown, the telescopic rod 20 includes two parts, namely a sleeve and an extension rod. The sleeve rod and the extension rod are slidably connected and cannot rotate relative to each other. The bevel gear 19, the bevel gear 21, the telescopic rod 20 and the helical gear 22 are arranged so that the hexagonal prism 8 can synchronously drive the two cutting knives 7 to rotate under the action of the bevel gear 19, the bevel gear 21, the telescopic rod 20 and the helical gear 22.

[0029] The upper end of the cutting frame 6 is fixedly connected with a return spring 23 located between the cutting frame 6 and the corresponding side moving frame 5 .

[0030] like Figure 6 As shown, setting a reset spring 23 can utilize the reset spring 23 to ensure that the cutting knife 7 always maintains contact with the soft porcelain, ensuring that the soft porcelain can be cut through to avoid adhesion, and can avoid the problem that the cutting knife 7 cannot rotate and is damaged due to interference contact with the protective plate, and at the same time can avoid the cutting knife 7 being stuck in the soft porcelain and causing damage when the cutting cannot be done.

[0031] The opposite ends of the two brackets 2 are respectively fixedly connected with hydraulic rods 24 , and the output ends of the hydraulic rods 24 are fixedly connected with the lifting frames 3 on the corresponding sides.

[0032] like Figure 5 As shown, the hydraulic rod 24 is provided so that the lifting frame 3 can be driven to move up and down by the hydraulic rod 24, thereby changing the position of the cutting knife 7.

[0033] An arc groove 25 is formed at the front end of the protective shell 17, and a lever 26 located in the arc groove 25 is fixedly connected to the lower side of the front end of the swing rod 11. An L-shaped fixing plate 27 is fixedly connected to the right end of the right bracket 2, and an inclined groove 28 is formed on the upper side of the fixing plate 27. The front end of the lever 26 is located in the inclined groove 28.

[0034] like Figures 5 and 6As shown, the arc groove 25, the lever 26, the fixing plate 27 and the inclined groove 28 are arranged to change the position of the spur gear 13 during the lifting process of the lifting frame 3, thereby ensuring that when the cutting knife 7 is raised to a certain height, it loses its power source and cannot continue to rotate. When the lifting frame 3 continues to rise, the insertion rod 14 on the upper spur gear 13 is inserted between the clamping columns 9 on the right side of the bidirectional screw 4, thereby enabling the width of the cutting knife 7 to be adjusted.

[0035] When the utility model is in use, the rotating motor 18 is started, and the toothed belt 16 can be driven to rotate through the rotating shaft 15, and then the spur gear 13 is driven to rotate through the toothed belt 16, and the insertion rod 14 on the upper spur gear 13 is connected with the corresponding side clamping column 9. At this time, the spur gear 13 can drive the bidirectional screw 4 to rotate, and the width of the left and right cutting knives 7 can be adjusted, and the width can be changed according to the required trimming width of soft porcelain, so as to facilitate production. After completion, the rotating motor 18 can be turned off;

[0036] After completing the width adjustment, the hydraulic rod 24 can be started to drive the lifting frame 3 to descend. During the descent of the lifting frame 3, the lever 26 moves leftward in the arc groove 25 under the action of the inclined groove 28. At this time, the lever 26 can drive the swing rod 11 to swing, and the upper spur gear 13 is disengaged from the bidirectional screw rod, and the lower spur gear 13 is connected with the hexagonal prism 8. When the lifting frame 3 descends to the lower end limit position, the lower spur gear 13 is completely connected with the hexagonal prism 8, and the cutting knife 7 contacts with the protection plate. The reset spring 23 shrinks to a certain extent, and then the rotating motor 18 is started. The rotating motor 18 can drive the toothed belt 16 to rotate the lower spur gear 13, and the spur gear 13 drives the hexagonal prism 8 to rotate. The hexagonal prism 8 drives the telescopic rod 20 to rotate through the action of the bevel gear 19 and the bevel gear 21. The telescopic rod 20 rotates through the lower bevel gear 21 and the bevel gear 22, thereby driving the two cutting knives 7 to rotate, and then the soft porcelain on the conveyor belt 1 can be trimmed and cut.

[0037] In the present invention, the rotary motor 18 and the hydraulic rod 24 are both prior art and will not be described in detail herein.

[0038] The specific embodiments described herein are merely examples of the spirit of the present invention. Those skilled in the art may make various modifications or additions to the specific embodiments described or replace them in similar ways, but they will not deviate from the spirit of the present invention or exceed the scope defined by the appended claims.
