As the utility model discloses a preferred technical scheme, the fixed baffle that is equipped with in bending plate both sides prevents that the waste wood bits from spilling from the side, improves the ability of taking out waste wood bits.

As a preferred technical scheme of the utility model, sand light area lower extreme one side is arranged in to the bent plate lower extreme, and with sand light area contactless, can not hinder the work in sand light area, the diameter of bent plate is the same with the diameter of convulsions chamber lower extreme, and the effect of taking out useless saw-dust is strengthened.

As a preferred technical scheme of the utility model, it is equipped with two sets ofly to go out the tuber pipe, still includes the air exhauster, and is connected with a tuber pipe, and this air exhauster is low-power air exhauster, need not high-power air exhauster.

Compared with the prior art, the beneficial effects of the utility model are that:

the utility model discloses narrow wide setting down in well convulsions chamber through going out the union coupling air exhauster, improves and takes out the sweeps effect, is close to sand light area lower extreme through the bending plate, and the sweeps of being convenient for gets into the intracavity portion of induced drafting, has further improved the discharge of sweeps.

In the figure: 1. sanding the belt; 2. rotating the guide roller; 3. an air draft cavity; 31. an air outlet pipe; 32. a bending plate; 33. and a baffle plate.

Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

Referring to fig. 1-2, the utility model provides an air draft mechanism for a wide belt sander, which comprises a sanding belt 1, wherein the sanding belt 1 is driven to rotate by a rotating guide roller 2, when the sanding belt 1 is sanded, waste scraps are ejected from the sanding belt 1 at the lower end, an air draft cavity 3 is fixedly arranged at one side of the sanding belt 1, the air draft cavity 3 is hollow and is sheet-shaped, the lower end of the air draft cavity 3 is open and has the same diameter as the sanding belt 1, the upper end of the air draft cavity 3 is blocked and has the diameter smaller than the diameter of the lower end, the thickness of the air draft cavity 3 is gradually reduced from top to bottom, a bending plate 32 is fixedly arranged at one side of the lower end of the air draft cavity 3, which is far away from the sanding belt 1, two sides of the bending plate 32 are fixedly provided with baffle plates 33, which prevent waste scraps from escaping from the side edges, the lower end of the bending plate 32 is arranged at one side of the sanding belt 1 and is not in contact, the effectual of accomodating to the sweeps, the sweeps most can both enter into convulsions chamber 3 insides through

bent plate

32, and 3 fixed being equipped with air-out pipes 31 in convulsions chamber upper end, and air-out pipes 31 link up with 3 insides in convulsions chamber mutually, and air-out pipes 31 are equipped with two sets ofly, still include the air exhauster, and are connected with air-out pipes 31, and this air exhauster is equipped with two sets ofly, and is low-power air exhauster, need not high-power air exhauster.
