[0001] The utility model relates to the technical field of dust collection equipment for a plate processing center, in particular to a dust collection device for a cutting machine with air blowing and bilateral dust collection. Background Art

[0002] With the emergence of microprocessors, the world has entered a brand-new numerical control era. Machine tools with multi-axis control that can only be achieved by computers have rapidly emerged, enabling the wood processing industry to enter an era of automation and intelligence. The application of numerical control wood processing centers in the wood processing field has become increasingly common.

[0003] In the prior art, a numerical control wood processing center can complete operations such as routing, vertical drilling, and grooving. With the aid of the wood processing center, it is convenient to process wood and can improve production efficiency. Existing domestic numerical control wood processing centers usually include a processing bed, a gantry, a sliding table, and a machine head. A table cushion for carrying plates is provided at the upper end of the processing bed. The gantry is horizontally movably arranged on the processing bed, the sliding table is longitudinally movably arranged on the gantry, the machine head is vertically movably arranged on the sliding table, and a pushing and dust collection mechanism is arranged on the gantry. Although it can perform pushing and dust collection through the pushing and dust collection mechanism, generally, only a number of dust collection holes are provided at the bottom of the pushing and dust collection mechanism, and dust and debris generated after plate processing are sucked through the dust collection holes. However, due to the limited dust collection capacity of the dust collection holes, some stubborn dust and debris cannot be sucked out, resulting in some un-sucked dust and debris remaining and poor dust collection effect.

[0004] Therefore, it is necessary to research a new technology to solve the above problems. Content of the Utility Model

[0005] In view of this, aiming at the deficiencies existing in the prior art, the main purpose of the utility model is to provide a dust collection device for a cutting machine with air blowing and bilateral dust collection, which can blow up un-sucked dust and debris through an air blowing mechanism and then suck them through the dust collection holes, thereby greatly improving the dust collection effect.

[0006] To achieve the above purpose, the utility model adopts the following technical solutions:

[0007] A dust collection device for a cutting machine with air blowing and bilateral dust collection includes a pushing plate, a pushing and dust collection cover, and a driving mechanism. The pushing plate is connected to the rear end of the pushing and dust collection cover and extends downward outside the lower end of the pushing and dust collection cover. The driving mechanism is connected to the upper end of the pushing and dust collection cover. A number of dust collection holes communicating with the dust collection cavity inside the pushing and dust collection cover are provided at the lower end of the pushing and dust collection cover. An air blowing mechanism is provided at the lower end of the pushing and dust collection cover for blowing up dust and debris, and the driving mechanism is used to drive the pushing and dust collection cover to move.

[0010] As a preferred solution, the blowing mechanism includes a blowing nozzle, and the blowing port of the blowing nozzle is exposed at the lower end of the material-pushing dust suction hood.

[0011] As a preferred solution, cleaning ears are connected to both the left and right ends of the material-pushing dust suction hood.

[0012] As a preferred solution, the driving mechanism includes a driving unit, a fixed rod, a first connecting rod, a second connecting rod, and a linkage rod. One end of the fixed rod is provided with a fixing plate portion for fixedly connecting to an external structure. One end of the driving unit is hinged to the other end of the fixed rod. The other end of the driving unit is connected to a movable rod, and the end of the movable rod away from the driving unit is connected to the linkage rod. One end of the first connecting rod is hinged to the fixed rod, and the other end is hinged to the linkage rod.

[0014] As a preferred solution, the upper end of the material-pushing dust suction hood is fixedly connected to the connecting plate of the linkage rod by screws.

[0015] The utility model has obvious advantages and beneficial effects compared with the prior art. Specifically, as can be seen from the above technical solution, it mainly sets a plurality of dust suction holes at the lower end of the material pushing and dust suction hood, and a blowing mechanism is arranged at the lower end of the material pushing and dust suction hood, so that the blowing mechanism is used to blow up dust and debris. In this way, it can blow up the dust and debris that have not been completely sucked by the blowing mechanism and then suck them through the dust suction holes, thus greatly improving the dust suction effect.

A plurality of dust suction holes communicating with the dust suction cavity inside the pushing dust collection cover 20 are provided at the lower end of the pushing dust collection cover 20. The driving mechanism 30 is used to drive the pushing dust collection cover 20 to move. And, in this embodiment, there are two driving mechanisms 30, and the two driving mechanisms 30 are arranged symmetrically left and right.

[0035] The driving mechanism 30 includes a driving unit 31, a fixed rod 32, a first connecting rod 33, a second connecting rod 34, and a linkage rod 35.
