Description

Technical Field

[0001] This utility model relates to the technical field of sandblasting equipment, specifically to a rear-end conveying mechanism for a sandblasting machine. Background Technology

[0002] Sandblasting is a process that uses the impact of a high-speed abrasive stream to clean and roughen the surface of a substrate. Powered by compressed air, it forms a high-speed jet that propels abrasive materials (copper ore sand, quartz sand, corundum, iron sand, Hainan sand) at high speed onto the surface of the workpiece. This alters the appearance or shape of the workpiece surface. Due to the impact and cutting action of the abrasive on the workpiece surface, the surface achieves a certain degree of cleanliness and varying roughness, improving the mechanical properties of the workpiece surface. This enhances the workpiece's fatigue resistance, increases adhesion between the workpiece and coatings, extends the durability of the coating film, and also facilitates coating leveling and decoration.

[0003] However, after sandblasting and polishing, personnel often need to conduct inspections. Traditional inspections can only check the upward-facing side of the workpiece, while the side of the workpiece in contact with the conveyor belt needs to be manually flipped over. Utility Model Content

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0015] This utility model embodiment provides a rear-end conveying mechanism for a sandblasting machine, such as... Figure 1-5 As shown, the device includes a base 1, a front worktable 2, a flipping mechanism 4, and a rear linkage mechanism 6. The front worktable 2 and the rear linkage mechanism 6 are arranged on the base 1 along its length, and the flipping mechanism 4 is positioned between the front worktable 2 and the rear linkage mechanism 6. The flipping mechanism 4 includes a drive motor 10, an arc-shaped frame 9, an arc-shaped plate 5, a movable insert plate 20, and a slide plate 21. The drive motor 10 is mounted on the front worktable 2, and the arc-shaped frame 9 is mounted on the output end of the drive motor 10. The arc-shaped plate 5 is mounted on the arc-shaped frame 9, and an opening 11 is provided on the arc-shaped plate 5. The slide plate 21 is vertically mounted on the arc-shaped frame 9, and the movable insert plate 20 is slidably fitted onto the slide plate 21. The movable insert plate 20 is adapted to the opening 11.

[0016] The flipping mechanism 4 also includes multiple drive wheels 3, which are equally spaced inside the arc plate 5 and the movable insert plate 20.

[0017] The rear-end linkage mechanism 6 includes a rear-end worktable 23, a fitting baffle 19, an insertion worktable 25, a first insertion rod holder 12, and a second insertion rod holder 13. The rear-end worktable 23 is mounted on the base 1, and the second insertion rod holder 13 is mounted on the rear-end worktable 23. The first insertion rod holder 12 is movably inserted into the second insertion rod holder 13, and the fitting baffle 19 is located at the end of the first insertion rod holder 12 away from the second insertion rod holder 13. The insertion worktable 25 is located between the two fitting baffles 19, passes through the opening 11, and corresponds to the front worktable 2.

[0018] The rear linkage mechanism 6 also includes two electrically operated telescopic rods 14, which are symmetrically arranged on both sides of the rear worktable 23. The movable ends of the electrically operated telescopic rods 14 are connected to the contact baffle 19.

[0019] The rear linkage mechanism 6 also includes a second drive slider 17, a vertical slide rail 18, a first drive slider 15, and a drive roller 22. A groove 8 is provided on the base 1, and the second drive slider 17 is slidably engaged in the groove 8. The vertical slide rail 18 is vertically mounted on the second drive slider 17, and the first drive slider 15 is slidably engaged in the vertical slide rail 18. The drive roller 22 is mounted on the first drive slider 15.

[0020] The rear linkage mechanism 6 also includes a first roller 16, a conveyor belt 7, and a second roller 24. The first roller 16 is pivotally connected to the insertion worktable 25, and the second roller 24 is pivotally connected to the rear worktable 23. The conveyor belt 7 is sleeved between the first roller 16, the drive roller 22, and the second roller 24.

[0021] Working Principle: During use, when personnel do not need to flip the workpiece for inspection, the movable insert plate 20 moves along the slide plate 21 to expose the opening 11. Simultaneously, the electric telescopic rod 14 extends, pushing the insert rod frame one 12 out from the insert rod frame two 13. At the same time, the second drive slider 17 moves, and the first drive slider 15 moves upward along the vertical slide rail 18, deforming the conveyor belt 7 between the first roller 16 and the second roller 24. This brings the conveyor belt 7 level with the insertion worktable 25. Then, the contact baffle 19 contacts the back of the arc-shaped frame 9, and the insertion worktable 25 contacts the front worktable 2, forming a complete linear conveying mechanism for convenient workpiece transfer.

[0022] When flipping is required, the insertion worktable 25 retracts, creating space for the opening 11. Then, the movable insertion plate 20 engages with the arc-shaped plate 5, forming an arc-shaped surface. As the workpiece moves onto the movable insertion plate 20, it is driven by the drive wheel 3 to move along the surface of the arc-shaped plate 5. Next, the drive motor 10 is controlled to flip the arc-shaped plate 5, and the workpiece flips under the action of centrifugal force.

[0023] In summary, the rear conveying mechanism of this sandblasting machine works in concert through the base 1, the front worktable 2, the flipping mechanism 4, and the rear linkage mechanism 6. This allows the machine to select between flipping and linear conveying. Flipping is activated when needed, while normal transport is possible by leaving through holes to facilitate the smooth passage of workpieces through the flipping device. This greatly simplifies operation.

[0024] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
