The application relates to the technical field of battery production and processing, and discloses a die cutting waste collecting device for battery production, which comprises a collecting box provided with a first screw rod, a pre-pressing box in communication with the collecting box, a second screw rod coaxially fixedly connected with the first screw rod and located in the pre-pressing box, an exhaust box provided with a plurality of first air vents and second air vents, the first air vents being in communication with the collecting box, the second air vents being in communication with the pre-pressing box, a compression box in communication with the pre-pressing box, a sealing plate arranged in the compression box, a driving piece arranged in the compression box and used for driving the sealing plate to seal or open the communication part of the pre-pressing box and the compression box, a pressing plate connected with one end of the sealing plate in the length direction, a collecting box provided with an opening and closing door, the collecting box and the compression box being in communication through the opening and closing door, a spacing for extruding waste being formed between the opening and closing door and the pressing plate, and exhaust holes being formed in the part of the collecting box close to the opening and closing door. The application can improve the collecting efficiency.

This utility model relates to the field of straw baling technology. The straw compression and baling device includes a processing box, with a compression box fixedly connected to one side of the bottom of the processing box. Two crushing shafts are rotatably connected inside the processing box, each with multiple crushing blades on its surface. First gears meshing with each other are fixedly connected to the front of each of the two crushing shafts. A first servo motor is installed on the front of the processing box. Two pressure rollers are rotatably connected inside the processing box. Through the synergistic action of the crushing shafts and the pressure rollers, the straw is initially compacted by the pressure rollers immediately after crushing, effectively reducing the material's bulkiness. This solves the problem of loose accumulation caused by straw falling directly into the compression chamber after crushing in the prior art, significantly increasing the straw density in the compression chamber. A single compression can form larger and denser clumps of straw, reducing the number of compressions and improving overall baling efficiency.

The application provides a method for reducing vibration by slanting blast hole trenching blasting, which sets a starting blasting area in front of a main blasting area, and specifically comprises the following contents: (1) at least five rows of blast holes with equal depth are set in the starting blasting area, and a blast hole in the middle is taken as a middle row; all the blast holes are slanting blast holes; one half-blast hole is set in the middle row; the blast holes on both sides of the middle row are slanting blast holes which are inclined to a reference surface; (2) the total charge amount of the blast hole in the middle row is 50-60% of the hole depth; the total charge amount of the half-blast hole is one third to one half of the hole depth; the total charge amount of the blast holes on both sides of the middle row is 45-50% of the hole depth; (3) the half-blast hole is first blasted, then the blast holes in the middle row are blasted one by one, and finally the other blast holes in the starting blasting area are blasted one by one; when blasting the blast holes in the starting blasting area, the blast holes are blasted one by one with time delay. The technical scheme of the application can effectively reduce the blasting vibration intensity.
