Abstract
Description
Technical Field
[0001] This utility model relates to the field of waste material suction technology for punch presses, and specifically to an automatic waste material suction device. Background Technology
[0002] A punch press, as a pressure processing device, can apply pressure to materials through a die, thereby achieving deformations such as punching, bending, and stretching to achieve the desired shape and size.
[0003] Using a punching die, a punch press can precisely punch out the desired shape from the workpiece. Waste generated during punching is typically discharged through a funnel at the bottom of the press. This funnel is prone to clogging and needs to be collected by a waste suction machine into a waste bin. Existing waste suction machines maintain a vacuum during the suction process. When in use, the waste from the punch press is sucked into the waste hopper by a fan and falls into the waste bin. The punch press must then be stopped; otherwise, the waste bin cannot be removed due to the vacuum. After stopping the machine, the waste bin must be manually dragged out, lifted to the waste disposal area, and bagged for disposal. This not only consumes manpower due to frequent waste bin changes but also causes the punch press to stop, affecting production. Summary of the Invention
[0004] In order to overcome the shortcomings and deficiencies of the existing technology, the purpose of this utility model is to provide an automatic waste suction device.
[0005] The purpose of this utility model is achieved through the following technical solution: an automatic waste suction device, including a housing, a sealed box connected inside the housing, a vacuum fan fixedly installed on the top of the sealed box, a suction pipe penetrating the housing and communicating with the inlet of the sealed box, and a vacuum pipe communicating with the outlet of the sealed box and the inlet of the vacuum fan.

[0018] To facilitate understanding by those skilled in the art, the present invention will be further described below with reference to embodiments and accompanying drawings. The content mentioned in the embodiments is not intended to limit the present invention.
[0019] like Figure 1-3 As shown, an automatic waste suction device includes a housing 1, a sealed box 3 connected inside the housing 1, a vacuum fan 2 fixedly installed on the top of the sealed box 3, a suction pipe 4 penetrating the housing 1 and communicating with the inlet of the sealed box 3, and a vacuum pipe 5 communicating with the outlet of the sealed box 3 and the inlet of the vacuum fan 2. The sealed box 3 has two sealed discharge valves, which work together to ensure that the sealed box 3 can continue to be vacuumed when discharging waste.
[0020] When the automatic waste suction device is in use, the vacuum fan 2 continuously evacuates the sealed box 3 to provide suction to the suction pipe 4, so as to suck up the waste from the punch press. After a certain amount of waste is collected, a first sealed discharge valve is opened, allowing the waste to fall onto the next sealed discharge valve of the sealed box 3 and accumulate. At this time, the sealed box 3 can still maintain suction by continuously evacuating the vacuum. Then, the first sealed discharge valve is closed and the next sealed discharge valve is opened, allowing the accumulated waste to be discharged from the sealed box 3. In actual use, a ton bag can be set below the sealed box 3 to collect a large amount of waste for a longer period of time, and then the ton bag can be directly transferred and replaced by a forklift. There is no need for the punch press to frequently stop to remove the waste box, which is beneficial to improving the processing efficiency of the punch press.
[0021] Furthermore, the sealed box 3 includes a box body 31, a partition 32 sealed in the middle of the box body 31, a breathable separation tank 33 connected to the top of the partition 32 and communicating with the suction pipe 4, a first unloading hopper 34 connected to the bottom of the partition 32 and communicating with the breathable separation tank 33, a first sealed discharge valve 35 connected to the discharge port of the first unloading hopper 34, a second unloading hopper 36 connected to the bottom of the box body 31, and a second sealed discharge valve 37 connected to the discharge port of the second unloading hopper 36. The partition 32 is used to divide the box body 31 into a first closed space 6 and a second closed space 7. The breathable separation tank 33, the first closed space 6 and the vacuum pipe 5 are connected in sequence. Specifically, the vacuum blower 2 continuously evacuates the first enclosed space 6 and the permeable separation tank 33 of the sealed housing 3 through the vacuum pipe 5, providing suction force for the suction pipe 4 to suck up waste material from the punch press. Air and waste material separate in the permeable separation tank 33, and the waste material falls into the first unloading hopper 34. After a certain amount of waste material is collected, the first sealed discharge valve 35 is opened, allowing the waste material to fall through the second enclosed space 7 of the sealed housing 3 into the second unloading hopper 36 for accumulation. At this time, the sealed housing 3 can still maintain suction force by continuously evacuating the vacuum. Subsequently, the first sealed discharge valve 35 is closed, and the second sealed discharge valve 37 is opened, allowing the accumulated waste material to be discharged from the second unloading hopper 36. In actual use, a ton bag can be placed below the sealed housing 3 to collect a large amount of waste material for a longer period, which can then be directly transferred and replaced by a forklift, eliminating the need for frequent shutdowns of the punch press to retrieve the waste box, thus improving the processing efficiency of the punch press. Furthermore, the sealed housing 3 also includes a sealed maintenance door 38 hinged to the side of the housing body 31.

[0027] Furthermore, the first enclosed space 6 of the sealed housing 3 is equipped with a first air filter 14, and the vacuum tube 5 is connected to the first air filter 14. The first air filter 14 helps to intercept waste debris from entering the vacuum tube 5.
[0028] Furthermore, the automatic waste suction device also includes an air outlet pipe 15 that penetrates the housing 1 and is connected to the air outlet of the vacuum fan 2, and a silencer 16 installed on the air outlet pipe 15, which helps to reduce noise.
[0029] Furthermore, the housing 1 has a ton bag loading / unloading port 17, and the automatic waste suction device also includes a tray 18 housed in the ton bag loading / unloading port 17.
