Description

Technical Field

[0001] This utility model relates to the field of shot blasting machine technology, and in particular to a mobile overhead conveyor shot blasting machine. Background Technology

[0002] Suspended through-type shot blasting machines are a common type of surface treatment equipment used for cleaning, rust removal, and surface treatment of various parts and workpieces. They are widely used in metal manufacturing, automotive industry, aerospace, casting, and welding.

[0003] A search of Chinese patent CN221111357U reveals an environmentally friendly overhead conveyor-type reinforced shot blasting machine, relating to the field of shot blasting machines. This invention addresses the problem of workpiece suspension in shot blasting machines. The machine includes a shot blasting chamber with an overhead conveyor rail mounted on its top surface via a bracket. Multiple sliders are slidably connected to the bottom surface of the overhead conveyor rail, and each slider has a suspension rod on its bottom surface. A guide opening is provided through the top surface of the shot blasting chamber. The application utilizes a limiting component to limit the suspension rods from the sliders, ensuring the rods are fixed outside the shot blasting chamber for easy workpiece suspension and stability during movement. The suspension rods can rotate inside the shot blasting chamber for easier workpiece processing. A baffle component blocks the through opening and guide opening, preventing debris from being ejected from the shot blasting chamber. Additionally, a counterweight at the bottom of the covering strip reduces the risk of the covering strip hooking onto the suspension hook, increasing the device's practicality.

[0004] Based on the above search results and existing technologies, the following findings were made:

[0005] In the above-mentioned technology, although the inside of the shot blasting machine can be sealed by the covering strip, and the parts can enter the shot blasting machine by passing through the covering strip, the collision between the parts and the covering strip may still cause the parts to fall off. Utility Model Content

[0006] To solve the above-mentioned technical problems, this utility model proposes a mobile overhead conveyor shot blasting machine that automatically opens and closes the movable door when entering the shot blasting machine, and seals the inside of the shot blasting machine while preventing parts from falling off due to collision.

[0007] The technical solution to achieve the purpose of this utility model is as follows: a mobile overhead conveyor shot blasting machine, including a shot blasting machine body, an overhead conveyor rail driven by an external device above the shot blasting machine body, an opening communicating with the interior of the shot blasting machine body at the top, multiple slides movably mounted on the overhead conveyor rail, the slides being able to move along the overhead conveyor rail, an mounting block fixedly mounted at the bottom of the slide, a suspension rod movably mounted on the mounting block, multiple hooks mounted on the suspension rod for suspending parts that need to be shot blasted, inlets and outlets on both sides of the shot blasting machine body, mounting shafts movably mounted inside the inlets and outlets, movable doors fixedly sleeved on the mounting shafts for sealing the interior of the shot blasting machine body, and a drive mechanism provided on the shot blasting machine body.

[0008] In some embodiments, the driving mechanism includes a transmission block, a driving rack, a driving gear, and push rods. The transmission block is a trapezoidal block that is movably installed inside the opening at a position corresponding to the movable door. The driving rack is fixedly installed on the side wall of the driving gear, and the driving gear is fixedly sleeved on the top of the mounting shaft. The driving rack and the driving gear mesh with each other. There are multiple push rods, which are respectively fixedly installed on the side wall of the mounting block.

[0009] In some embodiments, a mounting spring is installed inside the shot blasting machine body at a position corresponding to the transmission block, and the transmission block is movably mounted inside the shot blasting machine body by the mounting spring.

[0010] In some embodiments, a transmission groove is provided inside the opening, and a transmission rack is fixedly installed in the middle of the transmission groove.

[0011] In some embodiments, the mounting block is provided with a transmission mechanism, which includes a connecting gear, a rotating shaft and a transmission gear. The mounting block is a hollow rectangular structure, and the top of the suspension rod extends upward through the bottom wall of the mounting block and is located inside the mounting block. The connecting gear is fixedly installed on the top of the suspension rod.

[0012] In some embodiments, the rotating shaft is embedded in the side wall of the mounting block, the transmission gear is fixedly sleeved on the rotating shaft, and the transmission gear and the connecting gear mesh with each other.

[0013] Compared with existing technologies, the significant advantages of this invention are:

[0014] This invention utilizes a drive mechanism. When the slide moves along the overhead catenary guide rail to move components into the shot blasting machine body, the push rod moves with the slide and mounting block. When the push rod reaches the position of the transmission block, its continuous movement compresses the inclined surface of the transmission block. The compressed transmission block moves towards the interior of the shot blasting machine body, thereby driving the drive rack. The drive rack meshes with the drive gear, causing the drive gear to rotate. The drive gear, in turn, drives the movable door to rotate via the mounting shaft. This allows the inlet and outlet to be moved, enabling components to enter the shot blasting machine body for shot blasting. Because the transmission block is mounted with a spring, when the push rod separates from the transmission block, the transmission block resets under the spring's action. The movable door then re-seals the inlet and outlet, thus sealing the interior of the shot blasting machine body during shot blasting. This achieves the effect of automatically opening and closing the movable door when components enter the shot blasting machine, and while sealing the interior, it also prevents components from falling due to collisions.

Detailed Implementation

[0022] The present invention will now be described in detail, and the technical solutions in the embodiments of the present invention will be clearly and completely described. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present invention.

[0023] This utility model provides an improved, easily movable overhead conveyor shot blasting machine. The technical solution of this utility model is as follows:

[0024] like Figure 1 and Figure 3 As shown, a mobile overhead conveyor shot blasting machine includes a shot blasting machine body 1. An overhead conveyor guide rail 2 driven by an external device is provided above the shot blasting machine body 1. An opening 3 communicating with the interior of the shot blasting machine body 1 is provided at the top of the shot blasting machine body 1. Multiple slides 4 are movably installed on the overhead conveyor guide rail 2. The slides 4 can move along the overhead conveyor guide rail 2. An mounting block 5 is fixedly installed at the bottom of the slide 4. A suspension rod 6 is movably installed on the mounting block 5. Multiple hooks 7 are provided on the suspension rod 6. The hooks 7 are used to suspend the parts that need to be shot blasted. Inlet and outlet 8 are provided on both sides of the shot blasting machine body 1. An installation shaft 10 is movably installed inside the inlet and outlet 8. The installation shaft 10 has a cylindrical structure. A movable door 9 is fixedly sleeved on the installation shaft 10. The movable door 9 is used to seal the interior of the shot blasting machine body 1. A drive mechanism is provided on the shot blasting machine body 1.

[0025] The drive mechanism includes a transmission block 11, a drive rack 12, a drive gear 13, and push rods 14. The transmission block 11 is a trapezoidal block, movably installed inside the opening 3 corresponding to the movable door 9. The drive rack 12 is fixedly installed on the side wall of the drive gear 13, which is fixedly sleeved on the top of the mounting shaft 10, and the drive rack 12 and drive gear 13 mesh with each other. There are multiple push rods 14, each a rectangular strip, fixedly installed on the side wall of the mounting block 5. Through the drive mechanism, when the slide 4 moves on the overhead guide rail 2 to move the parts into the shot blasting machine body 1, the push rods 14 move with the slide 4 and mounting block 5. When the push rod 14 moves to the position of the transmission block 11, its continuous movement will compress the inclined surface of the transmission block 11. When block 11 is compressed, it moves toward the interior of the shot blasting machine body 1, thereby driving the drive rack 12 to move. The drive rack 12 meshes with the drive gear 13, causing the drive gear 13 to rotate. The drive gear 13 then drives the movable door 9 to rotate via the mounting shaft 10. At this time, the inlet and outlet 8 are driven, and the parts can enter the interior of the shot blasting machine body 1 for shot blasting cleaning. A mounting spring 15 is installed inside the shot blasting machine body 1 at the position corresponding to the transmission block 11. The transmission block 11 is movably mounted inside the shot blasting machine body 1 via the mounting spring 15. Since the transmission block 11 is mounted via the mounting spring 15, when the push rod 14 separates from the transmission block 11, the transmission block 11 will reset under the action of the mounting spring 15. At this time, the movable door 9 will also reseal the inlet and outlet 8, thereby sealing the interior of the shot blasting machine body 1 during shot blasting cleaning.

[0026] like Figure 1 and Figure 4 As shown, the opening 3 has a transmission groove 16 inside. The transmission groove 16 is a rectangular groove. A transmission rack 17 is fixedly installed in the middle of the transmission groove 16. The mounting block 5 has a transmission mechanism inside, which includes a connecting gear 18, a rotating shaft 19, and a transmission gear 20. The mounting block 5 is a hollow rectangular structure. The top of the suspension rod 6 extends upward through the bottom wall of the mounting block 5 and is located inside the mounting block 5. The connecting gear 18 is fixedly installed on the top of the suspension rod 6. The rotating shaft 19 is a cylindrical structure and is embedded in the mounting block 5. On the side wall of block 5, the transmission gear 20 is fixedly sleeved on the rotating shaft 19, and the transmission gear 20 meshes with the connecting gear 18. When the mounting block 5 moves into the interior of the opening 3, the transmission gear 20 will move into the interior of the transmission groove 16 and mesh with the transmission rack 17. As the mounting block 5 moves, the transmission gear 20 will be driven to rotate, which in turn will drive the connecting gear 18 to rotate. The connecting gear 18 will then drive the suspension rod 6 to rotate. The rotation of the suspension rod 6 will allow the parts to rotate inside the shot blasting machine body 1, improving the cleaning effect.

[0027] The specific working method is as follows:

[0028] With the drive mechanism in place, when the slide 4 moves on the overhead guide rail 2 to move the parts into the shot blasting machine body 1, the push rod 14 moves with the slide 4 and the mounting block 5. When the push rod 14 moves to the position of the transmission block 11, the continuous movement of the push rod 14 will squeeze the inclined surface of the transmission block 11. After being squeezed, the transmission block 11 will move towards the interior of the shot blasting machine body 1, thereby driving the drive rack 12 to move. The drive rack 12 and the drive gear 13 mesh with each other, and the drive gear 13 will be driven to rotate. The drive gear 13 can then drive the movable door 9 to rotate through the mounting shaft 10. At this time, the inlet and outlet 8 will be driven, and the parts can enter the interior of the shot blasting machine body 1 for shot blasting cleaning. Since the transmission block 11 is installed by the mounting spring 15, when the push rod 14 is separated from the transmission block 11, the transmission block 11 will be reset under the action of the mounting spring 15. At this time, the movable door 9 will also reseal the inlet and outlet 8, thereby sealing the interior of the shot blasting machine body 1 during shot blasting cleaning.
