Description

Technical Field

[0001] The utility model relates to the technical field of sandblasting machines, in particular to a sandblasting machine provided with a bar supporting roller. Background Art

[0002] A sandblasting machine is a type of air conveying machine that uses compressed air to transport powdered granular materials from one place to another in a pipeline. In the process of converting kinetic energy into potential energy, the high-speed moving sand particles are sprayed on the surface of the object, thereby improving the surface quality of the object. In the processing of rods, due to the beautification requirements of some customers for the surface of the rods, there is also a need for sandblasting of the rods. However, since the length of the rods far exceeds the length of the sandblasting chamber of the sandblasting machine, a single rod often needs to be sandblasted multiple times, which has the following problems. First, if the rods are located outside the sandblasting machine without support, it is easy for the center of gravity of the rods to be located outside the sandblasting machine. In this case, the rods may tilt, and in severe cases, even leave indentations on the rods located at the edge of the sandblasting chamber. Second, the rod perforation size for the sandblasting machine is fixed. When the rod size is much smaller than the hole size, there is a possibility that the metal sand of the sandblasting machine will leak out of the hole.

[0040] Embodiment Four

[0041] In view of the requirement of surface beautification of part of the rod, the metal sand with a diameter of 0.1 mm is replaced by the metal sand with a diameter of 0.3 mm. However, after the replacement, the weight of the metal sand is increased due to the increase of the diameter of the metal sand. The suction force provided by the negative pressure is insufficient to transfer the metal sand with a diameter of 0.3 mm. In order to solve the above problem, the spiral cage mechanism is arranged at the bottom of the iron sand recovery bin 3. The metal sand with a diameter of 0.3 mm is lifted to a certain height by the spiral cage mechanism, and then the metal sand is sucked into the sand blasting machine by the negative pressure to complete the recycling.
