Liftable extension plates 6 are provided on both sides of the processing table 5. A lifting device for driving the extension plates 6 to rise and fall is provided on the processing table 5. When the extension plates 6 descend to contact the base 1, the upper surface of the extension plates 6 is flush with the upper surface of the processing table 5.

[0025] The lifting device includes two sets of mounting brackets 9 that are fixedly connected to both sides of the base 1. A lead screw 10 is rotatably connected to the inner wall of each mounting bracket 9. A motor 11 for driving the lead screw 10 to rotate is installed on the mounting bracket 9. A nut seat 12 is sleeved on each lead screw 10. The side wall of one side of the nut seat 12 fits against the inner wall of the mounting bracket 9 to prevent the nut seat 12 from rotating during movement. The nut seats 12 on both sides are fixedly connected to the side walls of the extension plates 6 on both sides.

[0026] The extension plate 6 is equipped with a fixing device for fixing leather. The side of the frame 2 near the processing table 5 is equipped with a movable push plate 7. The side wall of the frame 2 is equipped with a moving device for moving the push plate 7. The push plate 7 is used to push the waste material off the processing table 5.

[0027] The fixing device includes a fixing frame 21 that is fixedly connected to the upper end face of the extension plate 6. An electric push rod 22 is fixedly installed on the upper end face of the fixing frame 21. The output end of the electric push rod 22 is fixedly connected to a clamping plate 23 that is slidably connected to the inner wall of the fixing frame 21.

[0028] The moving device includes a through slot on the side wall of the frame 2 and a rack 13 that is slidably connected to the inner wall of the through slot. A horizontal plate 14 is fixedly connected to the side wall of the frame 2. A gear 15 that meshes with the rack 13 is rotatably connected to the horizontal plate 14. A second motor 16 for driving the gear 15 to rotate is installed on the horizontal plate 14. The second motor 16 is a servo motor. The output shaft of the second motor 16 is connected to the shaft of the gear 15. One end of the gear 15 is fixedly connected to the push plate 7.

[0029] A protruding rod 17 is fixedly connected to the upper end face of the base 1, and a groove 18 is provided on the lower end face of the rack 13 for the protruding rod 17 to be inserted and moved. A limiting block 19 is fixedly connected to the side wall of the end of the protruding rod 17 that is inserted into the groove 18, and a limiting groove 20 is provided on the inner wall of the groove 18 for the limiting block 19 to be inserted and moved.

[0030] A cavity 27 is provided inside the base 1. A material collection channel 8 is provided on the upper surface of the base 1. The material collection channel 8 is connected to the cavity 27. The material collection channel 8 is located on the side of the processing table 5 away from the frame 2. The side wall of the material collection channel 8 is flush with the side wall of the processing table 5. An opening communicating with the outside is provided on one side of the cavity 27. A door panel 24 is embedded in the opening. A collection box 25 for putting into the cavity 27 is fixedly connected to the side wall of the door panel 24. A door handle 26 is fixedly connected to the side wall of the door panel 24 away from the collection box 25.

[0031] Working principle: The leather to be punched is placed on the processing table 5, positioned below the punching bit 4. At this point, the edges of the leather rest on the extension plates 6 on both sides. The extended electric push rod 22 drives the clamping plate 23 to press down, clamping and fixing the edges of the leather onto the extension plates 6. Then, the hydraulic cylinder 3 and the punching bit 4 punch holes. After punching, the motor 11 drives the lead screw 10 to rotate, causing the nut seat 12 to move upwards. The nut seat 12 then lifts the extension plates 6, thus... The punched leather is lifted upwards, while the waste material generated from the drilling remains on the processing table 5 through the opening in the leather. Then, the motor 16 drives the gear 15 to rotate, which in turn drives the meshing rack 13 to move closer to the processing table 5. The push plate 7 will also be pushed towards the processing table 5. The lower end of the push plate 7 is flush with the upper end of the processing table 5, so the push plate 7 can pass under the leather and push the waste material remaining on the processing table 5 down, so that the waste material falls into the collection box 25 in the cavity 27 through the collection channel 8 for collection.

[0032] After collection, the gear 15 is driven to rotate in the opposite direction by motor 2 16, and the push plate 7 is driven to return to its original position by rack 13. Then, the lead screw 10 is driven to rotate in the opposite direction by motor 11, and the nut seat 12 and extension plate 6 are driven to descend back to their original positions. Then, the electric push rod 22 is shortened to lift the clamping plate 23, and the leather is removed for the next round of processing. The operator can hold the handle and pull the door panel 24 and the collection box 25 directly out of the cavity 27 to clean the waste in the collection box 25. The cleaning and collection are more convenient and save a lot of manpower.

[0033] Meanwhile, as the rack 13 moves with the rotation of the gear 15, one end of the protrusion 17 is always inserted into the groove 18, and the limiting block 19 is always inserted into the limiting groove 20. The side wall of the limiting block 19 fits against the inner wall of the limiting groove 20, making the rack 13 more stable during translation.

[0034] The above description is merely a preferred embodiment of this utility model. The protection scope of this utility model is not limited to the above embodiments. All technical solutions falling within the scope of this utility model's concept are protected. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of this utility model should also be considered within the protection scope of this utility model.
