Description

Technical Field

[0001] This utility model relates to the field of rust removal machine technology, specifically a rust removal cylinder for a rust removal machine. Background Technology

[0002] In the field of metal processing, rust removal from metal surfaces is a crucial and fundamental process. Rust can have many adverse effects on the performance, appearance, and subsequent processing of metals. For example, it can reduce the corrosion resistance of metals and cause uneven metal surfaces, thus affecting the quality of subsequent coating or joining operations.

[0003] Traditional rust removal methods, such as manual sanding and wire brush cleaning, have significant drawbacks. Manual sanding is not only extremely labor-intensive, requiring workers to expend a great deal of physical strength, but also has very low rust removal efficiency, making it difficult to meet the needs of large-scale, high-efficiency production, thus affecting the overall service life of the equipment. Therefore, a rust removal cylinder for a rust removal machine is proposed to solve the above problems. Utility Model Content

[0004] The purpose of this utility model is to provide a rust removal cylinder for a rust removal machine to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a rust removal cylinder for a rust removal machine, comprising a cylinder body, a servo motor disposed inside the port of the cylinder body, one end of the servo motor being connected to a rotating shaft, a first gear being connected to the rotating shaft, and a second gear meshing with one side of the first gear, a roller being disposed inside the second gear, a spring being connected inside the roller via a helical rod, and a connecting rod being connected to the other end of the spring, the other end of the connecting rod being connected to a mounting base, a rust removal scraper being fixedly connected to the lower end of the mounting base, and a collection box being disposed at the bottom of the inner end of the cylinder body.

[0006] Preferably, one end of the rotating shaft is fixedly connected to the servo motor, and the other end is rotatably connected to the cylinder. The rotating shaft has two sets of gears distributed on the left and right sides of the lower end of the second gear, and the first gear and the second gear mesh with each other.

[0007] Preferably, the roller is provided with rectangular grooves evenly spaced on it.

[0008] Preferably, the outer surface of the spiral rod is evenly distributed with threads, the spiral rod is threaded into the inner wall of the drum, and the inner wall of the drum is provided with a threaded slot that matches it.

[0009] Preferably, the connecting rod is configured in an inverted T-shape, with one end of the connecting rod movably inserted into the helical rod, and the helical rod having a slot inside that mates with the connecting rod. Both ends of the spring are fixedly connected to the helical rod and the connecting rod.

[0010] Preferably, the other end of the connecting rod is inserted into the mounting base, and a locking bolt is inserted into the mounting base. The connecting rod has a locking groove that cooperates with the locking bolt.

[0011] Preferably, both ends of the collection box are movably engaged with the cylinder by locking blocks, and the inner wall of the cylinder is provided with a slot that cooperates with the locking blocks.

[0012] This utility model provides a rust removal cylinder for a rust removal machine, which has the following beneficial effects: the cylinder structure allows for continuous or batch loading of workpieces to be processed, realizing uninterrupted rust removal operations, and is especially suitable for processing a large number of small metal parts (such as screws, nuts, precision parts, etc.), with efficiency far exceeding manual grinding. All workpieces undergo the same processing process and time in the cylinder, avoiding product quality differences caused by fatigue and uneven force during manual operation.

[0013] One of the core advantages is the design of the spring components and connecting rods. This allows the scraper to adaptively press against the workpiece surface. For irregularly shaped or uneven workpieces, the spring provides constant and gentle pressure, ensuring effective rust removal while preventing damage to the metal substrate due to excessive pressure (such as excessive scratching or deformation). The collection box at the bottom of the cylinder effectively collects and processes rust dust, debris, and flaking material generated during the rust removal process. This prevents dust from spreading, greatly improves the air quality in the working environment, protects worker health, and meets the environmental protection requirements of modern production, facilitating the centralized collection and recycling of waste.

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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.

[0018] like Figures 1 to 4 As shown, this embodiment proposes a rust removal cylinder for a rust removal machine, including a cylinder body 1. A servo motor 2 is installed inside the port of the cylinder body 1, and one end of the servo motor 2 is connected to a rotating shaft 3. A first gear 4 is connected to the rotating shaft 3, and a second gear 5 is meshed on one side of the first gear 4. A roller 6 is provided inside the second gear 5. A spring 8 is connected inside the roller 6 through a spiral rod 7, and the other end of the spring 8 is connected to a connecting rod 9. The other end of the connecting rod 9 is connected to a mounting base 10. A rust removal scraper 11 is fixedly connected to the lower end of the mounting base 10. A collection box 12 is provided at the bottom of the inside of the cylinder body 1.

[0019] One end of the rotating shaft 3 is fixedly connected to the servo motor 2, and the other end is rotatably connected to the cylinder 1. The rotating shaft 3 has two sets distributed on the left and right sides of the lower end of the second gear 5. The first gear 4 meshes with the second gear 5. The two sets of rotating shafts 3 are symmetrically distributed on both sides of the second gear 5 and mesh with it, forming a stable three-point support transmission structure. This structure can counteract the radial force when the single gear is driven, reduce the shaking and noise when the drum 6 rotates, and improve the overall running stability. The method of fixing one end of the rotating shaft 3 and rotatably connecting the other end ensures efficient power transmission and reduces shaft wear caused by long-term operation.

[0020] The roller 6 has rectangular slots evenly distributed on it. The left and right ends of the collection box 12 are movably engaged with the cylinder 1 by locking blocks. The inner wall of the cylinder 1 has slots that cooperate with the locking blocks. The rectangular slots can efficiently discharge rust chips generated during the rust removal process, preventing them from accumulating inside the roller 6 and affecting the rust removal effect. The movable connection structure between the locking blocks and the slots allows the collection box 12 to be quickly disassembled and assembled, making it convenient to clean rust chips. It also has good sealing performance, reducing the leakage of rust chips and environmental pollution.

[0021] The outer surface of the spiral rod 7 is evenly threaded. The spiral rod 7 is threaded into the inner wall of the roller 6, and the inner wall of the roller 6 has a threaded slot that mates with it. The connecting rod 9 is designed with an inverted T-shape. One end of the connecting rod 9 is movably inserted into the spiral rod 7, and the spiral rod 7 has a slot that mates with the connecting rod 9. Both ends of the spring 8 are fixedly connected to the spiral rod 7 and the connecting rod 9. The other end of the connecting rod 9 is inserted into the mounting base 10, and the mounting base 10 has a locking bolt. The connecting rod 9 has a locking groove that mates with the locking bolt. The spiral rod 7 is connected to the roller 6 by threads. The extension length of the rust removal scraper 11 can be precisely adjusted by rotation to adapt to different rust thicknesses or workpiece surface flatness requirements. The elastic buffering effect of the spring 8 allows the rust removal scraper 11 to maintain appropriate pressure when in contact with the workpiece, ensuring rust removal force while avoiding damage to the rust removal scraper 11 or workpiece caused by hard contact. The inverted T-shaped design limits the radial sway of the connecting rod 9, ensuring the stability of the rust removal scraper 11 during high-speed rotation. The cooperation between the locking bolt and the locking groove facilitates quick replacement of different types of rust removal scrapers 11 (such as scrapers of different hardness and shape) and can firmly fix them during operation to prevent them from falling off.

[0022] Working principle: First, place the workpiece in the drum 6, turn on the servo motor 2, and the motor drives the rotating shaft 3 to rotate. The first gear 4 and the second gear 5 on the rotating shaft 3 mesh, driving the drum 6 to rotate. The extension length of the rust removal scraper 11 is adjusted by the screw rod 7 so that it contacts the surface to be rusted. The spring 8 plays a buffering role to ensure that there is appropriate pressure between the scraper and the workpiece. When the drum 6 rotates, the rust removal scraper 11 scrapes the surface of the workpiece to remove the rust layer. The scraped rust chips fall into the collection box 12 below through the opening on the drum 6. Turn off the motor, take out the collection box 12 to clean the rust chips, and replace or adjust the scraper if necessary.
