Description

Hand Push Belt Sander

technical field

The utility model relates to a grinding device, in particular to a hand-push abrasive belt grinding machine.

Background technique

Flat-plate welds are generally ground straight with abrasive belts. The welded seam after grinding with abrasive belt has narrow welding width and smooth welding seam. However, the general abrasive belt grinder is a fixed structure, which is very inconvenient to move, and the tension of the abrasive belt cannot be adjusted or the adjustment range is small, which limits the use effect of the abrasive belt grinder.

SUMMARY OF THE INVENTION

In view of the deficiencies in the prior art, in order to realize the grinding efficiency of the flat welding seam, the technical scheme provided by the present invention is as follows:

A hand-push abrasive belt grinder is characterized in that it comprises: a handle 1, a cylinder 2, a driving wheel 7, a driven wheel 8, a transmission wheel 9, an abrasive belt 4, and a motor 5;

The handle 1 is fixed with the bracket 6 , the cylinder 2 , the driving wheel 7 , the driven wheel 8 , and the motor 5 are installed on the bracket 6 , a rubber roller 3 is installed under the bracket 6 , and the transmission wheel 9 It is connected to the cylinder 2 , the motor 5 is connected to the driving wheel 7 , and the abrasive belt 4 surrounds the outer side of the driving wheel 7 , the driven wheel 8 and the transmission wheel 9 .

After the motor 5 is started, the driving wheel 7 is driven to rotate, thereby driving the driven wheel 8 and the transmission wheel 9 to rotate, and the abrasive belt 4 rotates. Adjusting the cylinder 2 drives the transmission wheel 9 to move up and down, so that the tension of the abrasive belt 4 can be greatly adjusted or replaced.

Beneficial effects: The hand-push abrasive belt grinder of the present utility model can easily move the abrasive belt grinder to any place through the handle and the rubber roller, and adjust the height of the transmission wheel up and down through the air cylinder, so that the abrasive belt can be stretched easily. Tightness adjustment.

Detailed ways

The utility model will be further described below with reference to the accompanying drawings and specific embodiments.

As shown in FIG. 1 and FIG. 2 , the hand-push type abrasive belt grinder in this embodiment is a schematic structural diagram of the hand-push type abrasive belt grinder in this embodiment.

(1) The hand-push belt grinder is composed of handle 1, cylinder 2, driving wheel 7, driven wheel 8, transmission wheel 9, abrasive belt 4, motor 5, etc.

(2) The handle 1 is fixed with the bracket 6 , and the cylinder 2 , the driving wheel 7 , the driven wheel 8 , and the motor 5 are installed on the bracket 6 .

(3) The rubber roller 3 is installed under the bracket 6 .

(4) The transmission wheel 9 is connected with the cylinder 2 .

(5) The motor 5 is connected to the driving wheel 7 .

(6) The abrasive belt 4 surrounds the outside of the driving wheel 7 , the driven wheel 8 and the transmission wheel 9 .

implementation plan:

After the motor 5 is started, the driving wheel 7 is driven to rotate, thereby driving the driven wheel 8 and the transmission wheel 9 to rotate, and the abrasive belt 4 rotates. The hand-push belt sander can be moved anywhere by pushing the handle 1 and the rubber roller 3. Adjusting the cylinder 2 drives the drive wheel 9 to move up and down, which can greatly adjust the tension of the abrasive belt 4, which is suitable for various grinding environments and facilitates the replacement of the abrasive belt.

The above embodiments are only to illustrate the technical idea of the present invention, and cannot limit the protection scope of the present invention. Any modification made on the basis of the technical solution according to the technical idea proposed by the present invention falls within the protection scope of the present invention. The technology not involved in the present invention can be realized by the existing technology.
