[0023] In this embodiment, the lifting and moving assembly includes two pairs of T-shaped cylinders 11 fixedly connected to the lower wall of the housing.

[0025] In this embodiment, the air guiding mechanism includes an annular baffle plate 2, which is mounted on the cylinder 1, and a fan 3 is mounted on one end of the annular baffle plate 2.
[0026] Its detailed connection method is a well-known technology in this field. The following mainly introduces the working principle and process, and the specific work is as follows.
[0027] Example: During the processing of plastic products, if the debris is not cleaned up in time, the small debris can easily enter the guide rail or other precision parts if blown by air, resulting in debris contamination. In order to facilitate the collection of large debris and prevent smaller debris from flying around, a debris collection device placed at the lower end of the processing equipment is designed.
[0028] In use, the device is moved to the working position by the casters 21 and then locked. The cylinder 18 is activated, and the second connecting rod 19 drives a pair of first rods 14 to move inside the two pairs of fixed plates 13. At this time, the first rack 15 can drive the meshing first gear 16 to rotate. The first gear 16 located on the same first connecting rod 17 rotates simultaneously. At this time, the first gear 16 meshes with the second rack 20, thereby moving the second rod 22 inside the T-shaped cylinder 11, thus opening the device. The height of the second rod 22 is adjusted, thereby aligning the annular baffle 2 with the bottom of the chip-producing end, so that the device can be conveniently adjusted for different heights.
[0029] At this time, the annular baffle plate 2 is located below the chip discharge end. At this time, the blower 3 is started. As the exhaust end of the blower 3 blows the air down through the inclined angle of the guide rod 4, the debris entering the cylinder 1 can be screened by the guide rod 4. Due to the design of double screening, the air entering the cylinder 1 can be guided by the C-shaped air guide plate 9, so that debris of different sizes can be collected in the filter bag inside the collection box 5 through the guide rod 4 and the isosceles trapezoidal discharge plate 8. Smaller debris can be guided by the frustum-shaped cylinder 10 and collected through the drawer 6. After the collection is full, it can be easily cleaned by taking out the drawer 6. Since the screening process is only for screening large particles, smaller particles such as dust will be collected in the filter bag corresponding to different screening mechanisms as the blower blows during the air blowing process.
[0030] With the assistance of a fan and guide components, the gas flows in a C-shape inside the cylinder 1, thereby blowing and collecting debris of different sizes. The equipment can be moved and adjusted to different positions and heights to adapt to the height of plastic processing equipment, thus achieving timely cleaning and collection of debris. It has a simple structure, is easy to maintain, has low cost, and is convenient to match the debris collection of different equipment.
