Description

Technical Field

[0001] The utility model relates to the technical field of log carving machines, in particular to a log carving machine. Background Art

[0002] The existing patent publication number (CN220463126U) discloses an engraving machine dust hood, which belongs to the technical field of engraving machine dust hoods. The key points of its technical solution include a box body, a closing mechanism, a lifting mechanism and a connecting mechanism. Through the setting of the closing mechanism, the closing mechanism includes a dust suction groove, a connecting plate and a dust cover, so that the closing mechanism can prevent dust from splashing and spreading during the engraving process. At the same time, the closing mechanism can be connected with the lifting mechanism. Through the setting of the lifting mechanism, the lifting mechanism can be adjusted according to the engraving depth. The dust cover is raised and lowered and the dust is collected and transported. Therefore, the closing mechanism and the lifting mechanism are used in conjunction, which can shield the dust and prevent the dust from splashing and spreading. In the process of engraving, the dust cover can be adjusted up and down at any time according to the engraving depth. Through the setting of the connecting mechanism, the connecting mechanism can be connected with a vacuum cleaner to achieve the effect of dust removal.

[0003] However, the structural design is relatively complex, and there is not enough air intake space, which will lead to difficulty in air intake. In addition, when carving the step surface, the side of the "closing mechanism" may come into contact with the step surface of the log and interfere when the engraving machine moves horizontally, causing its "closing mechanism" to deform. Utility Model Content

[0004] The technical problem to be solved by the utility model is: in order to overcome the above problems, a log carving machine is provided, which solves the above problems.

[0005] The utility model solves the technical problem by adopting the following technical solutions:

The exhaust pipe joint is externally connected to an exhaust hose and exhausts air under the action of an exhaust pump, and exhaust ports connected to the negative pressure air cavity are provided at annular intervals on the inner wall of the integrated dust hood. When the exhaust pump is started, the negative pressure air cavity becomes a negative pressure state and the wood chips under the integrated dust hood are sucked away through the exhaust port. An embedding groove is provided on the lower end surface of the integrated dust hood, a colloid is fixedly provided in the embedding groove, and a brush is fixed in the colloid, and the lower end of the brush is against the upper end surface of the log.

[0009] Preferably, the engraving drill bit is driven by a transmission flexible shaft, thereby engraving the log fixed on the board support table, which effectively reduces the weight of the equipment.

[0010] Preferably, the length of the brush is greater than the maximum engraving depth of the engraving drill bit, thereby ensuring that the integrated dust hood will not interfere with the log.

[0011] Preferably, the width of the air extraction port is not greater than the inner diameter of the air extraction pipe joint.

[0022] An annular negative pressure air cavity 20 is provided in the integrated dust hood 17, and an exhaust pipe joint 19 connected to the negative pressure air cavity 20 is fixedly provided on the side of the integrated dust hood 17. The exhaust pipe joint 19 is externally connected to an exhaust hose and exhausts air under the action of an exhaust pump, and exhaust ports 21 connected to the negative pressure air cavity 20 are provided at annular intervals on the inner wall of the integrated dust hood 17. When the exhaust pump is started, the negative pressure air cavity 20 becomes a negative pressure state, and the wood chips under the integrated dust hood 17 are sucked away through the exhaust port 21. An embedding groove 22 is provided on the lower end surface of the integrated dust hood 17, a colloid 23 is fixedly provided in the embedding groove 22, and a brush 24 is fixedly provided in the colloid 23, and the lower end of the brush 24 is against the upper end surface of the log.

[0023] Preferably, the engraving drill bit 18 is driven by a transmission flexible shaft, thereby engraving the log fixed on the plate support platform 25, which effectively reduces the weight of the equipment.

[0024] Preferably, the length of the brush 24 is greater than the maximum engraving depth of the engraving drill bit 18, thereby ensuring that the integrated dust hood 17 does not interfere with the log.

[0025] Preferably, the width of the air extraction port 21 is not greater than the inner diameter of the air extraction pipe joint 19 .
