Description

Technical Field

[0001] This utility model belongs to the field of rocker arm processing technology, and in particular relates to a hot air circulation drying device for paint on the surface of a rocker arm. Background Technology

[0002] The rocker arm commonly referred to in the internal combustion engines of automobiles, ships, motorcycles, and reciprocating aircraft engines is a type of rocker arm that transmits radial motion through the camshaft's cam angle, causing linear motion on the lift valve. This extends the rocker arm, and under the action of the camshaft's rotating blades, one end rises or falls, while the other end acts on the valve stem. When the camshaft blades raise the outer rocker arm, the internal force presses against the valve stem, opening the valve. When the outer rocker arm is allowed to return due to the camshaft's action, the inner rocker arm rises, allowing the valve spring to compress and close the valve. After machining, automotive rocker arms require painting, followed by drying, to provide wear-resistant and rust-proof protection.

[0003] After the rocker arm is coated with paint, it needs to be processed in a drying room. Hot air circulation drying room is often used to dry the rocker arm paint. During the drying process, the rocker arm is mostly in a static state. As the distance between the rocker arm and the hot air outlet varies, the uniformity of the heating of the rocker arm may be different. Therefore, a hot air circulation drying device for the rocker arm surface paint is needed. The rack can be rotated back and forth in the drying chamber, so that the rack drives the rocker arm to be heated evenly, thereby improving the uniformity of the rocker arm paint drying process. Utility Model Content

[0004] The purpose of this invention is to provide a hot air circulation drying device for paint on the surface of a rocker arm, in which the carrier rotates back and forth in the drying chamber, so that the carrier drives the rocker arm to be heated evenly, thereby improving the uniformity of paint drying process on the rocker arm and solving the technical problems mentioned in the background art.

[0009] Preferably, the top end of the L-shaped rod extends into the inner cavity of the slot frame, and a rotating sleeve is rotatably connected to the surface of the L-shaped rod, the rotating sleeve being in contact with the inner wall of the slot frame.

[0010] The beneficial effects of this utility model are:

[0011] 1. This utility model uses a turntable to drive the second rotating rod to rotate, which in turn moves the slot frame through the L-shaped rod. The slot frame then drives the gear to rotate back and forth through the rack. The gear then drives the material rack to rotate back and forth in the inner cavity of the drying box through the first rotating rod. This achieves the purpose of making the material rack rotate back and forth in the drying box, so that the material rack drives the rocker arm to be heated evenly, thereby improving the uniformity of paint drying process.

A groove frame 17 is fixedly connected to the bottom of the rack 16.

[0025] Example 2:

[0026] Figure 1-5 This invention illustrates an embodiment of a rocker arm surface paint hot air circulation drying device, comprising a drying chamber 1; a hot air circulation assembly 2 is mounted on the surface of the drying chamber 1; a material carrier 3 is provided in the inner cavity of the drying chamber 1; a bottom box 4 is bolted to the bottom of the drying chamber 1; a frame plate 5 is fixedly connected to the inner wall of the bottom box 4; two symmetrically arranged turntables 6 are rotatably connected to the surface of the frame plate 5; a belt 7 is connected to the surfaces of the two turntables 6 for transmission; a motor 8 is bolted to the surface of the frame plate 5; a U-shaped frame 9 is fixedly mounted on the inner wall of the bottom box 4; a rotating rod 10 is rotatably connected to the inner wall of the U-shaped frame 9; and casters 11 are mounted on the bottom of the material carrier 3. The casters 11 provide vertical support for the rotation of the material carrier 3 within the inner cavity of the drying chamber 1, preventing the material carrier 3 from tilting during rotation. When swaying occurs, a gear 12 is fixedly connected to the bottom end of the rotating rod 10, and a rotating rod 13 is rotatably connected to the inner wall of the U-shaped frame 9. The bottom end of the rotating rod 13 is fixedly connected to the turntable 6, and an L-shaped rod 14 is fixedly connected to the top end of the rotating rod 13.

[0027] Working Principle: When using this utility model, the user places the car rocker arm in the material rack 3, then closes the drying chamber 1 and turns on the hot air circulation component 2 for hot air drying. Subsequently, the motor 8 is turned on. At this time, under the transmission action of the belt 7, the turntable 6 drives the rotating rod 13 to rotate. Then, the rotating rod 13 moves the slot frame 17 through the L-shaped rod 14, causing the slot frame 17 to drive the gear 12 to reciprocate through the rack 16. During this process, the slide rail 15 limits the movement of the rack 16 and the slot frame 17, ensuring the stability of the rack 16 and the slot frame 17 during movement and preventing them from shaking during movement. Then, the gear 12 drives the material rack 3 to reciprocate in the inner cavity of the drying chamber 1 through the rotating rod 10, realizing the reciprocating rotation of the material rack in the drying chamber, so that the material rack drives the rocker arm to be heated evenly, thereby improving the uniformity of the paint drying process of the rocker arm.

[0028] In summary, this hot air circulation drying device for the surface paint of the rocker arm rotates by turning plate 6, which drives rotating rod 13 to rotate. Rotating rod 13 then moves slot frame 17 via L-shaped rod 14. Slot frame 17 drives gear 12 to rotate reciprocally via rack 16. Gear 12 then drives material rack 3 to rotate reciprocally within the drying chamber 1 via rotating rod 10. This achieves the goal of reciprocating rotation of the material rack within the drying chamber, ensuring that the material rack drives the rocker arm to be heated evenly, thereby improving the uniformity of paint drying during the rocker arm drying process.
