The tension spring 53 is extended and retracted by the inner cylinder 52 sliding in the outer cylinder 51, so that the mounting frame 21 can be moved away from or close to the frame 10, so as to adjust the distance between the two mounting frames 21 and adjust the cutting length of the material plate.

[0035] refer to Figure 2 and Figure 5 The pushing mechanism 60 includes a supporting tube 61, a short push rod 62, a long push rod 63 and a boss 64. The supporting tube 61 is fixedly installed between the rotating table 42 and the mounting tube 32, and the supporting tube 61 and the rotating table 42 are coaxially arranged. There are two short push rods 62 and two long push rods 63, and they are slidably assembled inside the supporting tube 61 along the radial direction of the supporting tube 61. The two short push rods 62 and the two long push rods 63 are symmetrically distributed in the supporting tube 61, and the short push rods 62 and the long push rods 63 are perpendicular to each other. There are two bosses 64 respectively fixedly installed on opposite sides of the two mounting frames 21. The short push rods 62 and the long push rods 63 can both abut against the bosses 64 during rotation and push the bosses 64 to make the two mounting frames 21 move away from each other. When the rotating table 42 rotates to rotate the adsorption table 30 to adjust the direction of the material sheet, the support tube 61 can rotate synchronously, so that the short push rod 62 gradually moves away from the boss 64 during rotation, and the long push rod 63 presses against the boss 64 during rotation, pushing the boss 64 to make the two mounting frames 21 move away from each other, and support the two mounting frames 21 to a farther position, so that the distance between the cutters 23 is increased, and then the cutter 23 can cut the short side of the material sheet, and the short push rod 62 and the long push rod 63 are slid in the support tube 61 to adjust their extension length, so that the support spacing of the two mounting frames 21 can be adjusted, and then the spacing between the two cutters 23 is changed, and the cutting length is adjusted, so as to facilitate cutting of material sheets of different sizes.

[0036] refer to Figure 5-Figure 8 The adjusting mechanism 70 includes a column 71, a ring body 72, an upper frame body 73, a lower frame body 74 and a connecting shaft 75. The column 71 is coaxially fixed to the middle part of the support cylinder 61. The ring body 72 has two ends respectively rotatably assembled at the upper and lower ends of the column 71. The upper frame body 73 and the lower frame body 74 are arc-shaped, and both have two. The two upper frames 73 are both arranged on the side wall of the ring body 72 located at the top, and the two lower frames 74 are both arranged on the side wall of the ring body 72 located at the bottom. There are a plurality of connecting shafts 75 respectively arranged in the upper frame body 73 and the lower frame body 74. The ends of the connecting shafts 75 in the two upper frames 73 are respectively fixedly mounted on the two short push rods 62, and the ends of the connecting shafts 75 in the two lower frames 74 are respectively fixedly mounted on the two long push rods 63. By rotating the ring body 72 outside the column 71, when driving the upper frame body 73 to rotate, the connecting shaft 75 can be pushed to drive the short push rod 62 to slide, and the extension length of the two short push rods 62 in the support tube 61 is adjusted, and the cutting position of the long side of the material plate by the cutter 23 is adjusted. When driving the lower frame body 74 to rotate, the connecting shaft 75 can be pushed to drive the long push rod 63 to slide, and the extension length of the two long push rods 63 in the support tube 61 is adjusted, and the cutting position of the width side of the material plate by the cutter 23 is adjusted.

[0037] Two symmetrical arc grooves 611 are provided on the side wall of the support cylinder 61, and connecting rods 612 are slidably mounted inside the two arc grooves 611. One end of the two connecting rods 612 extends into the support cylinder 61 and is fixedly connected to the upper frame 73 and the lower frame 74 respectively. The other ends of the two connecting rods 612 are fixedly installed with locking plates 613 located on the outside of the support cylinder 61. The internal threads of the locking plates 613 are connected with locking bolts 614. A plurality of bolt holes 615 matching the locking bolts 614 are provided on the side wall of the support cylinder 61 along its circumferential direction, and the tail end of the locking bolt 614 is threadedly connected to one of them. In the bolt hole 615, by pushing the locking plate 613 to drive the connecting rod 612 to slide in the arc groove 611, the upper frame 73 or the lower frame 74 can be rotated with the ring body 72, and then the extension length of the short push rod 62 or the long push rod 63 in the support tube 61 is adjusted to adjust the support distance of the two mounting frames 21, and then the locking bolt 614 is rotated to make its tail end screwed into the corresponding bolt hole 615, so that the position of the upper frame 73 or the lower frame 74 can be locked so that it can no longer rotate, and then the extension length of the short push rod 62 or the long push rod 63 is locked, so as to adjust the equipment to cut material plates of different sizes.

[0038] Working principle: according to the size of the required material sheet, adjust the short push rod 62 and the long push rod 63 to the appropriate extension length, and the short push rod 62 supports the two mounting frames 21 to the appropriate distance, and then the conveyor belt 12 conveys the material sheet to between the two mounting frames 21, so that the two long sides of the material sheet enter the support platform 22 in the two mounting frames 21 respectively, and the vacuum pump cooperates with the vacuum suction cup 31 to adsorb the material sheet, and then the hydraulic cylinder 212 pushes the knife holder 211 down, and after the pressing plate 214 presses the material sheet, the cutter 23 cuts the long side of the material sheet, and the collection box 217 recycles the cut waste; The knife holder 211 is lifted and reset, and the motor 43 drives the rotating table 42 to rotate 90 degrees, driving the adsorption table 30 and the material sheet to rotate synchronously. At the same time, the support cylinder 61 rotates with the rotating table 42, so that the short push rod 62 gradually moves away from the boss 64 during the rotation, and the long push rod 63 contacts the boss 64 during the rotation, pushing the boss 64 to move the two mounting frames 21 away from each other, increasing the distance between the two mounting frames 21, so that the short side of the material sheet moves to the support table 22 during the rotation, and then the cutter 23 cuts, completing the trimming of the four sides of the material sheet; After cutting is completed, the rotating table 42 rotates and resets, the long push rod 63 moves away from the boss 64, and the two mounting frames 21 approach each other under the action of the tension spring 53. The boss 64 is supported by the short push rod 62 again, and the vacuum pump is adjusted to release the adsorption of the vacuum suction cup 31 on the material sheet, so that the conveyor belt 12 outputs the cut material sheet and unloads the new material sheet, and conveys the new material sheet between the two mounting frames 21 for a new round of trimming processing.

[0039] In the present invention, the short push rod 62, the long push rod 63 and the boss 64 cooperate with each other to better adjust the distance between the two mounting frames 21, and can quickly determine the distance between the two cutters 23 to ensure that the material plate reaches the required length after trimming. After one set of opposite sides of the material plate is trimmed, the distance between the two cutters 23 can be quickly adjusted by rotating the material plate and the short push rod 62 and the long push rod 63, so that the cutter 23 is accurately moved to the corresponding position required for the cutting of the other set of opposite sides of the material plate, and the uncut opposite sides of the material plate are synchronously fed under the cutter 23, and then the cutting is quickly completed, and the material plate is cut to the required size. Without the need for multiple sets of cutting equipment to cooperate, the cutting of the four sides of the material plate can be completed efficiently and accurately, reducing the trimming cost. At the same time, it can also reduce the equipment footprint, shorten the material plate conveying process, and reduce the risk of the material plate being scratched and damaged during conveying. By adjusting the length of the short push rod 62 and the long push rod 63 extending in the support tube 61, the support distance of the short push rod 62 and the long push rod 63 to the two mounting frames 21 can be adjusted, and then the cutting distance between the two cutters 23 can be adjusted to facilitate the trimming of material plates of different sizes, thereby improving the versatility of the equipment and expanding the scope of application of the equipment.

A person skilled in the art may change, modify, replace and vary the above embodiments within the scope of the present invention.
