Abstract

A roller assembly includes a workbench, a roller module located above the workbench, and a locking assembly coupled to the roller module and configured to position the roller module above the workbench. The roller module includes a driving device and a pressure roller. The driving device is coupled to the pressure roller through a crank assembly. The crank assembly drives the pressure roller to move along a track to roll on a work-piece positioned on the workbench.

First claim

What is claimed is:

1. A roller assembly comprising:
a workbench;
a roller module located above the workbench; and
a locking assembly coupled to the roller module and configured to position the roller module above the workbench;
wherein the roller module comprises a driving device and a pressure roller;
wherein the driving device is coupled to the pressure roller through a crank assembly; and
wherein the crank assembly drives the pressure roller to move along a track to roll on a work-piece positioned on the workbench;
wherein the locking assembly is movably mounted on the workbench, the locking assembly is provided with a linking assembly comprising a fixing bar and a handle, the fixing bar is coupled to the roller module, the handle is configured to drive the fixing bar to move the roller module and lock a position of the roller module.

2. The roller assembly of claim 1 , wherein the workbench comprises a platform and a pair of support frames; the platform holds the work-piece in place; the pair of support frames is erected on opposite sides of the platform; a top of each of the support frames comprises a sliding board; the locking assembly is located on the sliding boards to allow the sliding boards to move and adjust a position of the roller module above the workbench.

3. The roller assembly of claim 2 , wherein the sliding board defines a sliding groove; the sliding groove receives a sliding seat of the locking assembly; the linking assembly is mounted on the sliding seat.

4. The roller assembly of claim 1 , wherein the roller module comprises a first guide board and a second guide board; the first guide board and the second guide board are spaced apart and face each other; the first guide board is located above the second guide board; the driving device is located on the first guide board; the crank assembly is located between the first guide board and the second guide board; the crank assembly is coupled to the pressure roller; the pressure roller faces the work-piece; an upper surface of the second guide board defines the track.

5. The roller assembly of claim 4 , wherein the driving device is a rotary handle located on an upper surface of the first guide board and pivotably coupled to the crank assembly; the crank assembly is rotationally driven by the driving device.

6. The roller assembly of claim 4 , wherein the crank assembly comprises a first crank and a second crank; one end of the first crank is coupled to the driving device; a second end of the first crank is slidably coupled to a first end of the second crank; a joint between the second end of the first crank slidably coupled to the first end of the second crank is adjacent to the track defined in the upper surface of the second guide board; a second end of the second crank is coupled to the pressure roller.

7. The roller assembly of claim 6 , wherein the joint between the first crank and the second crank comprises two bearings facing the second guide board; the two bearings are received within the track of the second guide board; the two bearings are movable within the track; the track controls a rolling path of the pressure roller coupled to the second crank.

8. The roller assembly of claim 6 , wherein the track follows a path around the upper surface of the second guide board; the second guide board defines a space surrounded by the track; the space is hollow and open toward the workbench; the pressure roller coupled to the second crank is received within the space; the pressure roller is limited to move within the space.

9. The roller assembly of claim 7 , wherein the pressure roller comprises a mounting seat, a clamping block, a pressure bar, and a roller wheel; the mounting seat is coupled to the second crank; the clamping block is located on the mounting seat; the clamping block clamps the pressure bar; a stopping block is located at a top of the pressure bar to limit an upper movement of the pressure bar; the roller wheel is located at a bottom of the pressure bar; the stopping block limiting upper movement of the pressure bar causes the pressure bar to apply pressure toward the workbench.

10. The roller assembly of claim 9 , wherein a top of the pressure bar comprises a top block; an interior of the pressure block comprises a spring and an adjusting screw; the spring is located between the top block and the adjusting screw; the adjusting screw adjusts pressure of the spring to control a rolling pressure of the roller wheel.
