[0002] The sandblasting machine uses compressed air as its power to form a high-speed jet beam to spray the material (copper ore sand, quartz sand, corundum, iron sand, Hainan sand) at high speed onto the surface of the workpiece to be processed, so that the appearance or shape of the outer surface of the workpiece changes. Due to the impact and cutting action of the abrasive on the workpiece surface, the surface of the workpiece acquires a certain degree of cleanliness and different degrees of roughness, and the mechanical properties of the workpiece surface are improved, thereby improving the fatigue resistance of the workpiece, increasing the adhesion between it and the coating, extending the durability of the coating, and also facilitating the leveling and decoration of the coating.

DETAILED DESCRIPTION

[0024] The following will be combined with the embodiments to clearly and completely describe the technical solution of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the utility model.

[0025] See also Figure 1-Figure 6 , the utility model provides a technical solution:

[0026] like Figure 1-Figure 2 As shown, a spraying component of a sandblasting device is used for spraying a cylindrical workpiece 6, the spraying component is located in a spraying box, the spraying component includes a first spraying mechanism 2 and a second spraying mechanism 3, the first spraying mechanism 2 is located on the upper side of the second spraying mechanism 3, a first conveyor belt 4 is provided below the first spraying mechanism 2, a second conveyor belt 5 is provided below the second spraying mechanism 3, the first conveyor belt 4 is provided with a limiting component 8 and a flipping component 7, the cylindrical workpiece 6 is fixed by the limiting component 8, the cylindrical workpiece 6 is flipped by the flipping component 7 and falls into the second conveyor belt 5.

[0027] Through the above technical solution, the cylindrical workpiece 6 is vertically fixed by the limiting assembly 8 at the feeding end of the first conveyor belt 4, and the cylindrical workpiece 6 is fed into the spray box 1 by the movement of the first conveyor belt 4. At this time, the top and one side of the cylindrical workpiece 6 are sandblasted and polished by the first spraying mechanism 2.

[0028] When the cylindrical workpiece 6 is driven by the first conveyor belt 4 to flip downward, the limiting assembly 8 is opened by the flipping assembly 7, and the cylindrical workpiece 6 falls from the limiting assembly 8 onto the second conveyor belt 5 below. At this time, the bottom surface of the cylindrical workpiece 6 faces upward, and the cylindrical workpiece 6 is moved by the second conveyor belt 5. The bottom surface and the side surface not sprayed by the first spraying mechanism 2 are sprayed by the second spraying mechanism 3. Then, the cylindrical workpiece 6 that has been sandblasted is sent out of the spraying box 1.

[0029] Through the cooperation of the first spraying mechanism 2 and the second spraying mechanism 3, sandblasting can be achieved on all parts of the cylindrical workpiece 6 to improve the grinding effect; at the same time, through the cooperation of the first conveyor belt 4, the second conveyor belt 5, the limiting component 8 and the flipping component 7, the cylindrical workpiece 6 can be automatically flipped, which reduces labor and improves sandblasting efficiency.

[0030] like Figure 1-Figure 4 As shown, the cylindrical workpiece 6 is placed between the stop block 82 and the first wedge block 84. The stop block 82 is a dovetail structure. The stop block 82 can be used to easily position the cylindrical workpiece 6. At the same time, under the action of the spring 85, the first wedge block 84 presses against the cylindrical workpiece 6, and the cylindrical workpiece 6 is clamped and fixed. When the cylindrical workpiece 6 is turned over by the first conveyor belt 4, the cylindrical workpiece 6 will not fall down under the action of the first wedge block 84 and the spring 85.

[0031] When the cylindrical workpiece 6 is completely facing downward, as the first conveyor belt 4 continues to rotate, the first wedge block 84 abuts against the second wedge block 71. Under the action of the inclined surface, the first wedge block 84 compresses the spring 85 to shrink to one side of the fixed block. At this time, the cylindrical workpiece 6 is released and falls under the action of gravity. It can be seen that since the flip assembly 7 is located below the spring 85, when the second wedge block 71 cooperates with the first wedge block 84, it will not contact and interfere with the spring 85 above. When the second wedge block 71 and the first wedge block 84 are staggered after the inclined surface is matched, the first wedge block 84 will reset under the action of the spring 85.

[0032] The cylindrical workpiece 6 dropped by the flipping assembly 7 will fall into the corresponding limiting ring 52 below. Since the distance from the highest point of the limiting ring 52 to the bottom plate 81 is greater than the height of the cylindrical workpiece 6, when the first conveying assembly rotates, the cylindrical workpiece 6 will not interfere or collide with the top of the limiting ring 52.

[0033] A bell mouth can be provided above the limiting ring 52 to facilitate the cylindrical workpiece 6 to fall smoothly into the limiting ring 52 . At this time, under the action of the limiting ring 52 , the cylindrical workpiece 6 will fall vertically downward until the bottom of the cylindrical workpiece 6 contacts the plate chain of the second conveyor belt 5 .

[0034] like Figure 5 and Figure 6 As shown, since the distance from the lowest point of the limiting ring 52 to the groove 51 is the same as the height of the cylindrical workpiece 6, when the cylindrical workpiece 6 contacts the plate chain of the second conveyor belt 5, the top of the cylindrical workpiece 6 has not completely separated from the limiting ring 52, and the cylindrical workpiece 6 will not move with the second conveyor belt 5. When the second conveyor belt 5 drives the plate chain to continue to move until the groove 51 approaches the cylindrical workpiece 6, the cylindrical workpiece 6 will fall into the groove 51, and the cylindrical workpiece 6 will be limited by the groove 51, and the cylindrical workpiece 6 will completely separate from the limiting ring 52, and the cylindrical workpiece 6 will move with the second conveyor belt 5.

[0035] Furthermore, the conveying directions of the first conveyor belt 4 and the second conveyor belt 5 are opposite, the feeding end of the first conveyor belt 4 extends out of the spray box 1, the discharging end of the second conveyor belt 5 extends out of the spray box 1, the first conveyor belt 4 is located above the second spray mechanism 3, and the second conveyor belt 5 is arranged correspondingly to the first conveyor belt 4. The spraying direction of the first spray mechanism 2 is opposite to the spraying direction of the second spray mechanism 3.

[0036] Through the above technical solution, the loading and dropping are located on the same side of the spray box 1, and one person can complete the loading and dropping of the cylindrical workpiece 6, which improves work efficiency and reduces costs. At the same time, the spraying directions of the first spray mechanism 2 and the second spray mechanism are opposite, and the cylindrical workpiece 6 is located in the middle of the two spraying directions, so the first spray mechanism 2 can be used to sandblast one side and the top surface of the cylindrical workpiece 6, and the second spray mechanism 3 can be used to sandblast the bottom surface and the other side of the cylindrical workpiece 6, so that all parts of the cylindrical workpiece 6 can be covered, and the sandblasting effect is improved.

[0037] The above is only a preferred embodiment of the utility model. It should be understood that the utility model is not limited to the form disclosed herein, and should not be regarded as excluding other embodiments, but can be used in various other combinations, modifications and environments, and can be modified within the scope of the concept described herein through the above teachings or the technology or knowledge of the relevant field. The changes and modifications made by those skilled in the art do not deviate from the spirit and scope of the utility model, and should be protected by the claims attached to the utility model.
