CN209520966U - A dust removal system for a planetary cutting machine - Google Patents

Abstract

The utility model relates to a dust removal system of a planet cutting machine, which comprises a turntable assembly and a saw blade cutting head which are arranged on a box body, wherein the box body is provided with a chip removal port communicated with a dust remover; the dust hood is arranged in the inner cavity of the box body and wrapped outside the saw blade cutting head, and a chip suction port in the dust hood is communicated with the chip exhaust port. The utility model effectively improves the negative pressure around the cutting station by arranging the dust hood outside the saw blade cutting head, further timely sucks away the scraps generated by cutting and finally discharges the scraps into the dust remover by pipeline conveying; because the negative pressure of the surrounding space of the scraps is increased, the dust absorption effect is greatly improved, and more than 98 percent of the scraps in the box body can be removed.

Description

A dust removal system for a planetary cutting machine

technical field

The utility model relates to a planet cutting machine, in particular to a dust removal system of the planet cutting machine.

Background technique

At present, the dust removal system in the existing planetary cutting machine is shown in Figure 1, which includes a turntable 2, a saw blade cutting head 3 and a hydraulic station 5 arranged on the box body 1, wherein the saw blade cutting head 3 is arranged in the box body 1 cavity, and the box body 1 is provided with a chip discharge port 6 connected to its inner cavity; in actual use, a large amount of debris will be generated when the saw blade on the saw blade cutting head 3 cuts, and the debris is absorbed by the dust collector from the chip discharge port. Port 6 is sucked away to achieve the effect of dust removal. The chip discharge port 6 in the existing dust removal system is generally arranged at the bottom of the box body 1. The dust collection effect of the dust removal system mainly depends on the negative pressure in the area where the chips are located. The chips are generated from the saw blade cutting head 3, and the saw blade The cutting head 3 is directly installed in the large space of the box body 1, and the air leakage is serious. The negative air pressure generated in the inner cavity of the box body 1, especially the end of the cutting head 3 of the saw blade is very small, resulting in the dust collection of the traditional dust removal system. The effect is poor, and generally only about 50% of the debris can be sucked away.

Therefore, further improvements are required.

Utility model content

The purpose of the utility model is to overcome the shortcomings of the above-mentioned prior art, and provide a dust removal system for a planetary cutting machine with simple design, reasonable structure, reliable performance and good dust removal effect.

The purpose of this utility model is achieved in that:

A dust removal system for a planetary cutting machine, including a turntable assembly and a saw blade cutting head arranged on a box body, the box body is provided with a chip discharge port connected to a dust collector; it is characterized in that: the box inner cavity is provided with The dust suction cover is wrapped around the outside of the cutting head of the saw blade, and the chip suction port on the dust suction cover is connected to the chip discharge port.

The turntable assembly includes a driving turntable and a driven turntable that are coaxially connected to each other and rotate synchronously, and the cutting head of the saw blade is arranged on the drive turntable.

The driven turntable is provided with an air chamber and an air inlet connected to the air chamber, the chip suction port is connected to the air inlet through the air duct, and the chip discharge port is connected to the air chamber.

Slewing bearings are arranged on the driving turntable and/or the driven turntable.

The beneficial effects of the utility model are as follows:

By installing a dust cover outside the cutting head of the saw blade, the negative pressure around the cutting station can be effectively increased, and the debris generated just after cutting can be sucked away in time, and the debris is finally discharged into the dust collector through pipeline transportation; Due to the increased negative pressure in the surrounding space of the debris, the dust collection effect is greatly improved, and more than 98% of the debris in the box can be removed.

Fig. 2 is a cross-sectional view of a planetary cutting machine in an embodiment of the present invention.

Detailed ways

Below in conjunction with accompanying drawing and embodiment the utility model is described further.

Referring to Fig. 2, the dust removal system of this planetary cutting machine includes a turntable assembly and a saw blade cutting head 3 arranged on the box body 1. The box body 1 is provided with a chip discharge port 6 connected to the dust collector; There is a dust collection cover 10 , which is wrapped around the outside of the saw blade cutting head 3 , and the chip suction port 1001 on the dust suction cover 10 communicates with the chip discharge port 6 . The dust removal system can effectively increase the negative pressure around the cutting station by setting a dust suction cover 10 outside the saw blade cutting head 3, and then suck away the debris just generated after cutting in time, and finally discharge the debris through pipeline transportation. into the dust collector; due to the increased negative pressure in the surrounding space of the debris, the dust collection effect is greatly improved, and more than 98% of the debris in the box can be removed

Further, the turntable assembly includes a driving turntable 7 and a driven turntable 9 that are coaxially connected to each other and rotate synchronously. The saw blade cutting head 3 is arranged on the drive turntable 7; The connecting rods 8 are fixedly connected to each other.

Furthermore, the driven turntable 9 is provided with an air chamber 901 and an air inlet 902 connected to the air chamber 901, the chip suction port 1001 is connected to the air inlet 902 through the air duct 11, the chip discharge port 6 is connected to the ventilation chamber 901, and the chip discharge port 6 Set on the wallboard of box body 1.

Further speaking, slewing bearings 4 are respectively arranged on the driving turntable 7 and the driven turntable 9 .

The above is the preferred solution of the utility model, showing and describing the basic principle, main features and advantages of the utility model.
