Description

Technical Field

[0001] The utility model specifically relates to the technical field of die-cutting machines, in particular to an automatic waste cleaning die-cutting machine based on negative pressure adsorption. Background Art

[0002] During the die-cutting process, especially for continuous die-cutting of materials like film and paper, the cutting tools generate a large amount of scrap material of varying sizes. This scrap material often scatters directly in the die-cutting area and around the equipment. If not promptly cleaned, it can easily accumulate in the working gap between the tool and the base, causing equipment jams, obstruction of guide roller rotation, and even tool misalignment and increased wear. Furthermore, this waste accumulation can obstruct the normal conveying path of the film material, resulting in defective products such as wrinkles and misalignment. In severe cases, it can force the production line to shut down for waste removal, significantly impacting production continuity.

[0003] While the negative pressure adsorption waste collection systems currently used in die-cutting machines can achieve basic waste extraction, they suffer from significant process flaws. These systems lack effective waste classification capabilities, leading to the accumulation of waste of varying particle sizes during transport, particularly in the filter area, resulting in complex blockages. This blockage not only causes a rapid decrease in system vacuum, forcing frequent maintenance shutdowns, but also leads to waste backflow and contamination of the processing area. Furthermore, the compressed accumulation of mixed waste significantly increases the difficulty of subsequent recycling. Utility Model Content

The adsorption covers 30 are used to collect waste generated during the processing of the film 20, and the waste enters the interior of the cleaning mechanism 40 through the connecting pipe 31.

[0022] The cleaning mechanism 40 includes a box body 41 and two sieve plates 45 arranged inside the box body 41, and the interior of the box body 41 is provided with an arc plate 414 and a partition plate 415, and the arc plate 414 and the partition plate 415 divide the internal space of the box body 41 into a processing chamber, a first collecting chamber and a second collecting chamber, wherein the processing chamber is located on the inner side of the arc plate 414, and there are two first collecting chambers, which are respectively arranged on the left and right sides of the arc plate 414, and the second collecting chamber is located on the lower side of the arc plate 414. The processing chamber is used to screen the waste and divide the waste into large-volume waste and small-volume waste. The first collecting chamber is used to collect large-volume waste, and the second collecting chamber is used to collect small-volume waste; further, in the embodiment of the present application, the box body 41 is fixedly installed with a frame 46 inside the processing chamber, and the two sieve plates 45 are rotatably installed on the left and right sides of the frame 46 through the rotating shaft 461, and the outer ends of the sieve plates 45 are fixedly connected with the arc baffle 44, and the arc baffle 44 is fitted with the inner wall of the curved plate 414; a first opening 416 is provided at the side of the curved plate 414, and a second opening 417 is provided at the bottom of the curved plate 414. The first opening 416 is communicated with the first collecting chamber, and the second opening 417 is communicated with the second collecting chamber. In the initial state, the sieve plate 45 maintains a horizontal position, and the waste enters the interior of the box and contacts the sieve plate 45. Small-volume waste in the waste passes through the sieve plate 45 and enters the lower space of the processing chamber, while large-volume waste It stays on the sieve plate 45 for a period of time, and then the two sieve plates 45 are controlled to rotate downward. During the rotation, the sieve plates 45 drive the arc baffle 44 to slide along the arc plate 414.

When the sieve plate 45 is in a horizontal state, the sieve plate 45 sorts the waste. When the sieve plate 45 tilts downward, the second opening 417 is blocked by the arc-shaped baffle 44, and the air flow enters the exhaust port 412 from the first opening 416. During the flow of air, the waste on the sieve plate 45 is driven into the first collection chamber, thereby improving the screening efficiency of the waste and avoiding the waste from being retained in the processing chamber.

[0024] In addition, if Figure 3 As shown, it should be noted that a filter is provided at the connection between the exhaust pipe 43 and the box body 41 and at the connection between the exhaust port 412 and the box body 41. The filter is used to block the discharge of waste and prevent waste from entering the exhaust pipe 43 or the exhaust port 412.

[0025] In the embodiment of the present application, a feed port is provided at the upper portion of the processing chamber, and a sliding plate 47 and a fixed plate 471 are provided at the feed port.

The bottom of the cylinder 421 is fixedly installed inside the outer cover 42, and the telescopic end of the cylinder 421 is fixedly connected to the backplate 49. After the waste classification is completed, the box doors 413 of the first collection chamber and the second collection chamber are opened, and the telescopic end of the cylinder 421 is extended to control the movement of the backplate 49, so that the backplate 49 pushes the waste out of the first collection chamber and the second collection chamber.
