Description

Technical Field

[0001] This utility model belongs to the field of polishing machine technology, specifically a surface polishing machine for cast iron products. Background Technology

[0002] Cast iron products are metal products made from cast iron as the main raw material through processes such as smelting, casting, cooling, and cleaning. They are widely used in many fields such as the automotive industry, machinery manufacturing, and construction. During the production process, cast iron products may have burrs on their surface, which require polishing. By placing the cast iron products and abrasive together into a drum polishing machine, the drum is rotated by a geared motor, causing the cast iron products and abrasive to rub and collide with each other, thereby removing impurities such as burrs and oxide scale from the surface of the cast iron products and improving the surface finish of the workpiece.

[0003] In existing technologies, small debris falls off cast iron products during the polishing process. When these debris comes into contact with the surface of the cast iron product at a certain speed and force, it may cause micro-cutting or plastic deformation, resulting in damage to the surface of the cast iron product. Moreover, some sharp small debris can easily cause scratches or indentations on the surface of the cast iron product, affecting the polishing effect. To address this issue, we propose a surface polishing machine for cast iron products. Utility Model Content

[0005] To achieve the above objectives, this utility model provides the following technical solution: a surface polishing machine for cast iron products, including a base frame and a rotating drum body rotatably mounted on the base frame. The rotating drum body is provided with a removal mechanism for removing debris. The removal mechanism includes a base plate embedded in the bottom of the rotating drum body. The base plate has multiple sets of triangular mesh holes inside for debris to fall off during the rotation of the rotating drum body.

[0006] Multiple sets of movable plates are evenly distributed at the bottom of the base plate and along its length. A fixed plate is fixedly installed at the end of each movable plate. A U-shaped vertical plate is fixedly installed at the bottom of the main body of the rotating drum. Two sets of screws are fixedly installed on the surface of the fixed plate.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] (1) This utility model uses a designed removal mechanism. The triangular mesh on the bottom plate works in conjunction with the low-speed rotation of the main body of the rotating drum to achieve automatic falling of debris by gravity. When the bottom plate rotates to the bottom of the main body of the rotating drum, the internal debris falls through the triangular mesh onto the inclined mesh plate, which significantly reduces the amount of debris in the main body of the rotating drum. This reduces the risk of debris causing micro-cutting, scratches and indentations on the surface of cast iron products, ensuring polishing quality. Moreover, the size of the triangular mesh can be flexibly changed according to the type of cast iron products, abrasive specifications and debris size. This ensures effective filtration of debris of different sizes and prevents abrasive leakage due to excessively large aperture, thus improving the applicability of the device.

[0016] (2) This utility model combines a long pipe, a nozzle and a connector. After polishing, some debris adheres to the inner wall of the baffle and the rubber baffle. The water supply pipe is connected through the connector. The long pipe can evenly distribute the water flow to multiple nozzles to form a high-pressure water mist to directionally rinse the attached debris. Compared with manual cleaning, it greatly improves cleaning efficiency, saves labor costs and reduces labor intensity. Attached Figure Description

Detailed Implementation

[0026] The technical solution of this utility model will be clearly and completely described below with reference to the embodiments. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0027] Example 1

[0028] Please see Figures 1-7 This utility model provides a technical solution: a surface polishing machine for cast iron products, including a base frame 103 and a rotating drum body 102 rotatably mounted on the base frame 103. The rotating drum body 102 is provided with a removal mechanism for removing debris. The removal mechanism includes a base plate 202 embedded in the bottom of the rotating drum body 102. The interior of the base plate 202 has multiple sets of triangular mesh holes 204. The bottom of the base plate 202 and the base plate 202 are evenly distributed with multiple sets of moving plates 203. The ends of the moving plates 203 are fixedly provided with fixed plates 205. The bottom of the rotating drum body 102 is fixedly provided with a U-shaped vertical plate 206. The surface of the fixed plate 205 is fixedly provided with two sets of screws 207. The outside of the screws 207 is respectively provided with a fixed ring and a threaded ring 208. The threaded ring 208 is connected to the screws 207 by threads, while the fixed ring is fixed to the screws 207.

[0029] Both the front and back of the rotating drum body 102 are provided with baffles 200. Two sets of connecting frames 201 are fixedly provided on the top of the baffles 200, and two sets of bottom columns are fixedly provided between the bottom of the connecting frames 201 and the base frame 103.

[0030] Multiple sets of rubber baffles 209 are distributed at the bottom of the baffle 200 and along the length of the baffle 200. The side view of the baffle 200 is a V-shaped structure.

[0031] This invention utilizes a designed removal mechanism. The triangular mesh 204 on the base plate 202 works in conjunction with the low-speed rotation of the rotating drum body 102, allowing debris to fall automatically under gravity. When the base plate 202 rotates to the bottom of the rotating drum body 102, the internal debris falls through the triangular mesh 204 onto the inclined mesh plate 104, significantly reducing the amount of debris inside the rotating drum body 102. This lowers the risk of debris causing micro-cutting, scratches, and indentations on the surface of cast iron products, ensuring polishing quality. Furthermore, the size of the triangular mesh 204 can be flexibly adjusted according to the type of cast iron product, abrasive specifications, and debris size, ensuring effective filtration of debris of different sizes while preventing abrasive leakage due to excessively large apertures, thus improving the applicability of the device.

[0032] In summary, the cover plate 101 is opened, and then the cast iron products and abrasive are placed into the rotating drum body 102 through the inlet at the open cover plate 101. Next, the cover plate 101 is closed, and the reduction motor 100 is started to drive the rotating drum body 102 to rotate at a slow speed. This satisfies the need for polishing the cast iron products and also allows small debris inside the rotating drum body 102 to fall to the bottom of the rotating drum body 102 due to gravity when the triangular mesh 204 on the bottom plate 202 is at the top of the rotating drum body 102. (It will not splash outward from the triangular mesh 204). At this time, the abrasive and the cast iron roll together inside the rotating drum body 102. The abrasive polishes the cast iron product by deburring. However, some small debris will fall off the cast iron product during the polishing process. When the bottom plate 202 on the rotating drum body 102 rotates to a position close to the bottom of the rotating drum body 102, the debris inside the rotating drum body 102 falls from the multiple triangular meshes 204 on the bottom plate 202 to the inclined mesh plate 104 below. This reduces the amount of small debris inside the main body 102 of the rotating drum, thereby reducing the impact of debris on cast iron products. Furthermore, the size of the triangular mesh 204 can be adjusted as needed. During adjustment, the threaded ring 208 is rotated away from the fixed plate 205 to loosen it. Then, the fixed plate 205 is moved towards or away from the apex of the triangular mesh 204. The moving fixed plate 205 then drives the screw 207 to slide within the U-shaped vertical plate 206, causing multiple sets of moving plates 203 to move towards or away from the apex of the triangular mesh 204. When the moving plate 203 approaches the apex of the triangular mesh 204, the size of the triangular mesh 204 begins to decrease. If the moving plate 203 moves away from the apex of the triangular mesh 204, the size of the triangular mesh 204 begins to increase. After adjustment, the threaded ring 208 is rotated towards the fixed plate 205 to tighten it, thus fixing the screw 207 and adjusting the size of the triangular mesh 204.

[0033] Meanwhile, when the main body 102 of the rotating drum rotates at a slow speed, some small debris is also prone to splashing outwards. At this time, the two sets of baffles 200 are set to block and protect the small debris that splashes out. At the same time, the multiple sets of rubber baffles 209 at the bottom of the baffles 200 also block and protect the small debris that splashes out, thus avoiding the chance of small debris splashing outwards.

[0034] Example 2

[0035] Please refer to Example 1. Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 7 and Figure 8 A long pipe 300 is fixedly installed on the top inner wall of the baffle 200, a number of nozzles 301 are fixedly installed at the bottom of the long pipe 300, and a connector 302 is fixedly installed at the top of the long pipe 300.

[0036] This invention combines a long pipe 300, a nozzle 301, and a connector 302. After polishing, some debris adheres to the inner wall of the baffle 200 and the rubber baffle 209. The water supply pipe is connected through the connector 302, and the long pipe 300 can evenly distribute the water flow to multiple nozzles 301 to form a high-pressure water mist to directionally rinse the attached debris. Compared with manual cleaning, this greatly improves cleaning efficiency, saves labor costs, and reduces labor intensity.

[0037] In summary, after polishing is complete, the main body 102 of the rotating drum stops rotating, and the cover plate 101 is located at the top of the main body 102 of the rotating drum. Then, the cover plate 101 is opened and the polished cast iron product is taken out. During the rotation of the main body 102, some debris splashes outward and is blocked by the baffle 200. At this time, many debris easily adheres to the inner wall surface of the baffle 200 and the inner wall surface of the rubber baffle 209. Then, by connecting a water supply pipe to the connector 302, water is sprayed onto the inner wall surface of the baffle 200 through multiple sets of nozzles 301 at the bottom of the long pipe 300 to rinse the attached small debris. During the rinsing process, the water flows down from the inner wall surface of the multiple sets of rubber baffles 209. At this time, the water flow can also rinse the small debris attached to the inner wall surface of the rubber baffles 209, saving the labor of manual cleaning.

[0038] In this embodiment, bearing seats are provided on the top of both sides of the base frame 103 to facilitate the rotation of the rotating shaft. Rotating shafts are fixedly provided on both sides of the rotating drum body 102, and the ends of the rotating shafts pass through the interior of the bearing seats.

[0039] In this embodiment, a reduction motor 100 is fixedly installed on the base frame 103. The reduction motor 100 can drive the rotating drum body 102 to rotate. A first wheel is fixedly installed at the working end of the reduction motor 100, and a second wheel is fixedly installed at the end of the rotating shaft. A transmission belt is sleeved between the first wheel and the second wheel.

[0040] In this embodiment, a cover plate 101 is rotatably mounted on the top of the rotating drum body 102 via two sets of rotating columns. The free end of the cover plate 101 is fixedly connected to the rotating drum body 102 by bolts. The bolts can fix the free end of the cover plate 101 to the rotating drum body 102, making it convenient to open or close the cover plate 101. After the cover plate 101 is opened, the inlet is exposed, making it convenient to take out or put in cast iron products and abrasives.

[0041] In this embodiment, an inclined mesh plate 104 is fixedly installed on the base frame 103. When the abrasive in the main body 102 of the rotating drum is taken out, the main body 102 of the rotating drum is rotated to the inlet removal state, and then the abrasive in the main body 102 of the rotating drum is poured out and falls on the inclined mesh plate 104. Through the inclined mesh plate 104, some small debris that has not been completely removed can fall from the mesh holes in the inclined mesh plate 104 into the collection container placed below in advance.

[0042] The above embodiments are only used to illustrate the technical methods of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical methods of this utility model without departing from the spirit and scope of the technical methods of this utility model.
