[0020] Example embodiments will now be described more fully with reference to the accompanying drawings. However, example embodiments can be implemented in a variety of forms and should not be construed as limited to the embodiments set forth herein; rather, these embodiments are provided to make the present invention more comprehensive and complete and to fully convey the concepts of example embodiments to those skilled in the art. The same reference numerals in the figures represent the same or similar structures, and thus their repeated description will be omitted.

[0021] The words expressing positions and directions described in the present utility model are all explained by taking the drawings as examples, but they can be changed as needed, and all the changes are included in the protection scope of the present utility model.

[0022] Reference Figure 1-3 The utility model provides a jet polishing machine, comprising: a workbench 1, a circulating polishing component 2 and an air nozzle 6.

[0023] A working cavity is provided inside the workbench 1, and a station for placing a workpiece is provided inside the working cavity. The working cavity provided inside the workbench 1 is a hollow cavity.

[0024] The circulating polishing assembly 2 includes a conveyor belt 3, a mixer 4 and a material receiving bin 5. The mixer 4 is arranged in the working chamber and has a relative output port and an inlet. The conveyor belt 3 is used to transport the abrasive particles in the material receiving bin 5 to the inlet of the mixer 4. The interior of the conveyor belt 3 is driven by a motor, and the power supply of the motor is connected to an external control cabinet.

[0025] The air nozzle 6 is arranged inside the workbench 1, and the spray direction of the air nozzle 6 intersects with the direction of the output port of the mixer 4, and is used to drive the material output from the output port to polish the workpiece on the workstation. The spray direction of the air nozzle 6 intersects with the direction of the output port of the mixer 4. When working, the abrasive particles are lifted to the top mixer 4 through the conveyor belt 3. Under the uniform centrifugal action of the mixer 4, the abrasive particles are fully stirred and evenly mixed, and then the abrasive particles are discharged from the output port, and are accelerated by the air nozzle 6 and blown to the surface of the workpiece to perform cyclic polishing on the surface of the workpiece. Avoid the dispersion of dust or particulate matter, which may cause the operator to inhale and affect their health. In addition, under the acceleration of the airflow and cyclic polishing, the surface of the workpiece can be effectively polished. And it will not affect the size of the workpiece surface.

[0026] In one embodiment, the end of the air nozzle 6 away from the workpiece is connected to an air pump, and the air pump is used to suck in external gas. The power supply of the air pump is connected to an external control cabinet. When working, the air pump pressurizes the external gas and ejects it from the air nozzle 6. The gas ejected from the air nozzle 6 carries abrasive particles and drives the abrasive particles toward the surface of the workpiece for polishing. The accelerated abrasive particles can effectively impact and polish the surface of the workpiece, and polish the surface of the workpiece to avoid burrs or redundant parts on the surface of the workpiece, which affects subsequent processing and machining.

[0027] In one embodiment, the conveyor belt 3 is rotatably connected to the inside of the working chamber, and is used to lift the abrasive particles in the receiving bin 5 to the input port of the mixer 4. The conveyor belt 3 rotates during operation, and carries the abrasive particles at the bottom of the receiving bin 5 to the mixer 4 at the top following the rotation of the conveyor belt 3, without the need for manual repeated collection of the abrasive particles, and the abrasive particles are circulated and polished.

[0028] In one embodiment, a rack 7 is further included, which is overlapped in the working chamber for placing workpieces. The rack 7 can be a hollow structure, with both ends overlapped in the working chamber, and the abrasive particles can fall into the material receiving bin 5 through the rack 7 after being flushed.

[0029] In one embodiment, the material receiving bin 5 is located at the bottom of the working chamber, and its opening faces upward.

[0030] Although the embodiments of the utility model have been shown and described above, it can be understood that the above embodiments are exemplary and cannot be understood as limitations on the utility model. Ordinary technicians in the field can change, modify, replace and modify the above embodiments within the scope of the utility model without departing from the principles and purpose of the utility model. All of these changes should fall within the scope of protection of the claims of the utility model.
