Description

Technical Field

[0001] This application belongs to the field of sandblasting machine technology, and particularly relates to a sandblasting machine with easily adjustable spray flow rate. Background Technology

[0002] A sandblasting machine is a device that uses compressed air as power. The working pressure established by the compressed air in the tank forces the abrasive material through the sand outlet valve into the sand delivery pipe and out through the nozzle to be sprayed onto the surface being processed, thereby improving the surface quality of the object. Sandblasting machines can give the surface of the workpiece a certain degree of cleanliness and different roughness, thus improving the mechanical properties of the workpiece surface. Therefore, sandblasting machines are widely used in the market.

[0003] However, existing sandblasting machines cannot adjust the flow rate of the sandblasting material during use, making them inconvenient to operate. This issue needs to be addressed. Utility Model Content

[0004] The purpose of this application is to address the aforementioned technical problems by providing a sandblasting machine that facilitates the adjustment of the jet flow rate, enabling the regulation of the jet flow rate of the sandblasting material.

A connecting pipe is connected between the extraction pipe and the injection head, and the connecting pipe is equipped with a second air pressure source; The adjustment mechanism includes an adjustment block, which is movably installed in the metering tank.

[0006] In the blasting zone, the workpiece to be sandblasted is placed on the blasting worktable. It can be placed directly on the blasting worktable or clamped on the blasting worktable using tooling fixtures. The blasting head sprays high-speed moving sandblasting material onto the workpiece to achieve the sandblasting process. The sandblasting chamber stores sandblasting material to supply the sandblasting head. The wheel in the sandblasting chamber is driven to rotate by a motor. During the rotation, the sandblasting material enters the metering tank. When the metering tank rotates to the extraction pipe, the extraction pipe has a slot that corresponds to and fits the wheel. The extraction pipe has an airflow provided by a first air pressure source, which blows the sandblasting material out of the metering tank, allowing the sandblasting material to move through the extraction pipe to the connecting pipe. The connecting pipe has an airflow provided by a second air pressure source. The sandblasting material moves with the airflow in the connecting pipe and is sprayed out by the blasting head. The adjusting mechanism controls the movement of the adjusting block in the metering tank to adjust the capacity of the metering tank. When the adjusting block moves towards the axis of the wheel, the capacity of the metering tank increases, thereby adjusting the amount of sandblasting material sprayed from the blasting head.

[0007] Furthermore, the adjustment mechanism includes: The adjustment section is installed and connected to the adjustment block; The wheel body is provided with a movable groove that is movably connected to the adjustment part.

[0008] Furthermore, the adjustment mechanism also includes: An adjusting disc is movably mounted in the wheel body. The adjusting disc is provided with adjusting grooves, which are evenly distributed in an arc shape around the axis of the adjusting disc. The adjustment section is equipped with an adjustment wheel corresponding to the adjustment groove.

[0009] Furthermore, the adjustment mechanism also includes: The worm gear is coaxially connected to the adjusting disc; The worm gear is mounted on the wheel body and connected to the worm wheel.

[0010] Furthermore, the sandblasting machine body also includes: The collection shell is placed below the spraying worktable; The collection pipe connects the collection shell and the sandblasting chamber.

[0011] Furthermore, the sandblasting chamber is equipped with a secondary storage chamber connected to the collection pipe.

[0012] Furthermore, the spraying worktable includes: Through holes are evenly distributed on the spraying worktable.

[0013] Furthermore, the sandblasting machine body also includes: The vibratory motor is installed on the outer wall of the sandblasting chamber.

[0014] The beneficial effects of this application are: 1. During the rotation of the wheel, the sandblasting material enters the metering tank. When the metering tank rotates to the extraction pipe, the extraction pipe blows the sandblasting material out of the metering tank. 2. The adjusting mechanism controls the movement of the adjusting block in the metering tank, thereby adjusting the capacity of the metering tank and thus adjusting the amount of sandblasting material sprayed from the spray head.

[0015] 3. When the adjusting disc rotates, the adjusting wheel moves in the adjusting groove, and the adjusting part moves in the movable groove to achieve the adjustment of the moving block in the quantitative groove. Attached Figure Description
