Description

Digital-controlled carving machine with wood chip clearing function

Technical field

The utility model is related to wood carving machine tool, more particularly to a kind of digital-controlled carving machine with wood chip clearing function.

Background technology

Engraving machine is a kind of embossment, flat carving, through-carved work or the default shape of cutting to be carried out to plank, furniture, acrylic etc. The plant equipment of shape.Equipped with the digital engraving machine of digital control system, due to its high precision, the CAD for designing can be introduced directly into Drawing, is widely used in furniture manufacturing field.

General digital-controlled carving machine includes digital control system and is controlled by it carrying out the engraving machine of template cutting, engraving machine sheet Body has including lathe bed, and plank to be carved is fixed on lathe bed, is additionally provided with what is acted relative to lathe bed along XYZ coordinate on lathe bed Main shaft, spindle nose sets the milling cutter of incised slab, and milling cutter is passed by default under the drive of main shaft according to the control of digital control system Path, carves on plank or cuts out preset shape.Milling cutter can produce substantial amounts of wood chip in incised slab, not only do The further cutting of milling cutter is disturbed, and, less particle can diffuse the health that operator is influenceed to airport in wood chip.

For this problem, Authorization Notice No. is a kind of automatic clear to be disclosed in the utility model patent of CN204641217U The digital-controlled carving machine of scrap is managed, it lays a deck panels in lathe bed upper surface, and some grooves for penetrating panel are offered on panel, Lathe bed top panel underface set with scrap bucket, its bottom is connected with a sack cleaner, be provided with around milling cutter with , be swept to scrap in groove using brush by the brush of milling cutter motion, is allowed to be reclaimed into scrap bucket through groove, works as scrap When scrap in bucket is accumulated to a certain amount of, opening sack cleaner carries out the recovery of scrap.

In structure disclosed in the patent, although brush can be swept near groove scrap, in order to ensure panel Intensity, groove will not be set too much, therefore, there is more dead angle on panel, brush takes here scrap to, and scrap also cannot Discharged by groove, piled up in the region that will be enclosed in brush, influence milling cutter work.

Utility model content

The purpose of this utility model is to provide a kind of digital-controlled carving machine with wood chip clearing function, and it is by wood chip The change of position is collected, makes just be taken away by wood chip collection device after producing wood chip on milling cutter, reduction wood chip is near milling cutter Accumulation.

Above-mentioned purpose of the present utility model technical scheme is that：One kind has wood chip clearing function Digital-controlled carving machine, include lathe bed and the main shaft acted relative to lathe bed, it is detachable on the main shaft to be provided with one and be servo-actuated Frame, the lower end of the arbitrary-movement articulator is provided with the brush of the milling cutter for surrounding main shaft lower end, and being additionally provided with one on the arbitrary-movement articulator wears The chip-removal hole of saturating arbitrary-movement articulator upper surface, the chip-removal hole passes through the external sack cleaner of flexible pipe.

Milling cutter is enclosed by using the brush of above-mentioned technical proposal, arbitrary-movement articulator lower end, makes the wood in milling cutter process Bits are enclosed below arbitrary-movement articulator, and the chip-removal hole on arbitrary-movement articulator is communicated to the wood chip storage region below arbitrary-movement articulator, sack cleaner Suction force by flexible pipe and chip-removal hole, the wood chip in region that can be surrounded brush is taken away at any time, prevents wood chip attached in main shaft It is near to pile up.Compared to prior art, this wood chip cleaning form is no longer changed to lathe bed structure, therefore can overcome existing In technology on panel dead angle problem, wood chip is produced at any time drains in the presence of sack cleaner at any time.And brush is in itself Can prevent wood chip from flying out to lathe bed other positions, lift the clean-up performance of engraving machine working environment.

Preferably, the arbitrary-movement articulator includes：

Connecting plate, upper end is detachably connected with the main shaft；

Top board, level is fixedly held to connecting plate bottom, the open-work that is passed through for milling cutter is provided with the top board and for even Connect the chip-removal hole of flexible pipe；
