Detailed ways

The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

Referring to FIG. 1 , it is a schematic structural diagram of an automatic waste discharge die-cutting machine according to an embodiment of the present invention. The automatic waste discharge die cutting machine of this embodiment includes a die cutting mechanism, a feeding mechanism 20, a material pulling mechanism 30 and a waste discharge mechanism.

The die-cutting mechanism includes a base 11 , an upper die holder 12 , a lower die holder 13 and a die-cutting knife assembly 14 . The lower mold base 13 is connected to the base 11 through the hydraulic mechanism 15 and forms a waste material tank 110 between the base 11. The lower mold base 13 is provided with a blanking hole 130 corresponding to the waste material tank 110, and the upper mold base 12 is arranged on the lower mold base 13. Above the mold base 13, and the upper mold base 12 can reciprocate up and down in the vertical direction relative to the lower mold base 13. The structure of the die cutter assembly 14 is shown in Figure 2 and Figure 3, the die cutter assembly 14 includes a cutter body 141, a buffer spring 142 and an ejector post 143, and the cutter body 141 is connected to the bottom of the upper die base 12 through a buffer spring 142. On the side, the tool body 141 has a through hole 144 that matches the blanking hole 130, and a knife edge 145 that forms a closed ring is provided around the through hole 144. The ejector column 143 is installed on the lower side of the upper mold base 12 and is located 145 and the upper die base 12, the ejector column 143 is matched with the through hole 144.

The feeding mechanism 20 and the pulling mechanism 30 are arranged on both sides of the upper mold base 12 and the lower mold base 13 respectively, the feeding mechanism 20 is used for conveying the material line 1 , and the material pulling mechanism 30 is used for pulling the material line 1 .

The exhaust mechanism includes a cylinder 41 , an air blowing part 42 and an air suction part 43 . The cylinder 41, the blowing part 42 and the suction part 43 are connected by a pipeline 44, the cylinder body 411 of the cylinder 41 is fixed on the base 11, the piston rod 412 of the cylinder 41 is fixedly connected with the upper mold base 12, and the blowing part 42 The blowing port of the blowing port and the suction port of the suction part 43 are respectively positioned at the both sides of the waste tank 110, the blowing port of the blowing part 42 is provided with a rubber sheet 421 which prevents air intake, and the bottom of the suction port of the suction part 43 is provided with a seal. waste collection box 45, the pipeline 44 between the suction part 43 and the blowing part 42 is provided with a one-way valve 441, wherein, when the upper mold base 12 moves to the lower mold base 13, the one-way valve 441 blocks the pipeline 44. The blowing port of the blowing part 42 blows the waste to the suction port of the suction part 43; when the upper mold base 12 moves upward, the one-way valve 441 communicates with the pipeline 44, and the suction port of the suction part 43 sucks the waste Waste collection box 45 .

Optionally, there are multiple air cylinders 41 , and the multiple air cylinders 41 are arranged in a straight line on one side of the base 11 , and each air cylinder 41 corresponds to its own air blowing portion 42 and air suction portion 43 . The increase in the number of the cylinders 41 can increase the displacement, make the blowing more powerful, and the cleaning of waste becomes more effective and thorough.

In this embodiment, the waste material collection box 45 is detachably connected to the suction part 43, so that the waste material collection box 45 can be replaced after being filled with waste materials.

When the automatic waste discharge die-cutting machine of this embodiment is working, when the cutter body 141 moves downward with the upper die base 13, the blade 145 first contacts and die-cuts the raw material. Since the blade 145 is a closed ring, the die-cut The waste material is the same as the closed ring, and then the tool body 141 continues to move downward along with the upper mold base 13. At this time, the buffer spring 142 is compressed, and the ejector column 143 pushes the waste material into the waste material groove 110 through the through hole 145.

When the upper mold base 12 moved upwards, the one-way valve 441 communicated with the pipeline 44, so the suction port of the suction part 43 began to suck air, and the waste was sucked into the suction port and fell into the waste collection box 45 under the action of gravity. The rubber sheet 421 of the air part 42 blocks the blowing port due to air pressure, preventing waste from entering the blowing part 42 through the blowing port. When the upper mold base 12 moves to the lower mold base 13, the one-way valve 441 blocks the pipeline 44 to prevent gas from entering the suction part 43 from the pipeline 44, so the gas can only be blown out from the blowing port of the blowing part 42, so that waste The waste in the tank 110 will be continuously blown to the suction port of the suction part 43, and accumulate near the suction port.

Through the above method, the automatic waste discharge die-cutting machine tool of the embodiment of the present invention die-cuts the raw material during the pressing process through the blade on the tool body, and the ejector column pushes the die-cut waste material into the waste material during the continuous pressing process of the tool body Groove, while the piston rod of the cylinder realizes circular blowing and air suction with the up and down reciprocating movement of the upper mold base. When blowing, the waste is blown to the suction port, and when inhaling, the waste is sucked by the suction port. Finally, the waste is blown by gravity It falls into the waste collection box under the action, avoiding the problem of manual cleaning taking time and affecting safety, so that the waste can be collected automatically without stopping the machine, which can facilitate the collection of waste, making waste cleaning more effective and thorough, and improving production efficiency. .

The above is only an embodiment of the present invention, and does not limit the patent scope of the present invention. Any equivalent structure or equivalent process conversion made by using the description of the present invention and the contents of the accompanying drawings, or directly or indirectly used in other related technologies fields, are all included in the scope of patent protection of the present invention in the same way.
