Description

Technical Field

[0001] This utility model relates to the field of polishing equipment technology, and more specifically, to a centrifugal grinding and polishing machine. Background Technology

[0002] Centrifugal polishing machines utilize the principle of centrifugal force to achieve high-speed polishing of workpieces within a polishing container. They employ a drive wheel driven by a rotating drum that revolves around its axis, while also rotating itself. This rotational friction significantly accelerates the speed of the workpiece being polished, causing the polishing abrasive within the container to undergo high-speed grinding. This results in the workpiece and the polishing abrasive tumbling and rubbing against each other at high speed within the working container, achieving the desired grinding state within the fixed container.

[0003] Abrasive is loaded into the polishing container, and the workpiece to be polished is placed inside. The friction between the workpiece and the abrasive polishes its surface. The abrasive needs to be replaced periodically to ensure high-quality polishing. Typically, an inclined guide plate is added to the bottom of the polishing container to tilt the abrasive out of the container, allowing it to slide automatically down the guide plate to the equipment's outlet for easy unloading and replacement. During unloading, abrasive often becomes stuck on the guide plate, requiring manual intervention to clean it out. This unloading method is inefficient and poses significant safety hazards due to the need for manual intervention. To address this issue, this application proposes a centrifugal grinding and polishing machine with high unloading efficiency and safety performance. Utility Model Content

[0004] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a centrifugal grinding and polishing machine with high unloading efficiency and high safety performance.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a centrifugal grinding and polishing machine, comprising a housing with an opening and a polishing container device located inside the housing, wherein a material guiding device is provided below the polishing container device, the material guiding device comprising a shaking plate, a receiving plate and a driving assembly, the receiving plate being located at the opening of the housing, the shaking plate being inclined, with its steeper end being mounted on the inner wall of the housing via rotating blocks on both sides, and its lower end extending to abut against the receiving plate, the driving assembly comprising a driving plate located at the bottom of the shaking plate and a driving part for driving the driving plate to move up and down.

[0006] The present invention is further configured such that: the driving part includes a driving source, a slide and a driving block, the driving block is fixed on the slide and driven to move left and right by the driving source, and the end of the driving plate is provided with a wavy concave-convex strip, so the end of the driving block abuts against the concave-convex strip.

[0007] The present invention is further configured such that: a toothed belt is provided at the bottom of the slide, and a gear is engaged on the toothed belt, and the drive source is connected to the gear.

[0008] The present invention is further configured such that: the driving source is a motor, and the output end of the motor is connected to a gear.

[0009] The present invention is further configured such that: the driving source includes a driving shaft, one end of which is connected to a gear, and the other end extends to the outside of the housing and is equipped with a handwheel.

[0010] By adopting the above technical solution, when unloading the abrasive in the polishing container device, the material is unloaded by the up-and-down moving shaking plate, which makes it less likely for the abrasive to be stuck or blocked, and allows it to move quickly to the opening of the machine casing, which facilitates rapid unloading, reduces manual operation by reaching into the machine casing, and avoids safety hazards.

[0016] Reference Figures 1 to 4 The embodiments of this utility model will be further described below.

[0017] A centrifugal grinding and polishing machine includes a housing 1 with an opening and a polishing container device 2 located inside the housing 1. A material guiding device is provided below the polishing container device 2. The material guiding device includes a shaking plate 3, a receiving plate 4, and a driving assembly. The receiving plate 4 is located at the opening of the housing 1. The shaking plate 3 is inclined, with its steeper end mounted on both sides of the inner wall of the housing 1 via rotating blocks 30, and its shorter end extending to abut against the receiving plate 4. The driving assembly includes a driving plate 31 located at the bottom of the shaking plate 3 and a driving part for driving the driving plate 31 to move up and down.

[0018] The driving unit includes a driving source 32, a slide 33, and a driving block 34. The driving block 34 is fixed on the slide 33 and is driven by the driving source 32 to move left and right. The end of the driving plate 31 is provided with a wavy convex and concave strip 310, so the end of the driving block 34 abuts against the convex and concave strip 310. The bottom of the slide 33 is provided with a toothed belt 330, on which a gear 35 meshes. The driving source 32 is connected to the gear 35.

[0019] The drive source 32 is a motor 320, and the output end of the motor 320 is connected to the gear 35. Using the motor 320 for drive increases automation. After the polishing container 2 is tilted to pour abrasive, the abrasive moves along the inclined surface of the shaking plate 3 to the receiving plate 4, facilitating unloading by the operator at the opening of the housing 1. During unloading, to prevent abrasive from remaining on the shaking plate 3, the motor 320 drives the gear 35 to rotate. The gear 35, in conjunction with the toothed belt 330, enables the slide block 33 to slide left and right. The slide block 33 drives the drive block 34 to move left and right. The end of the drive block 34 continuously contacts the uneven strip 310 on the drive plate 31. Through the contact of the end faces of different thicknesses on the uneven strip 310, the shaking plate 3 moves up and down, accelerating the movement of the abrasive and achieving rapid unloading.

[0020] The drive source 32 includes a drive shaft 321, one end of which is driven through a gear 35, and the other end extends to the outside of the housing 1 and is equipped with a handwheel 322. By operating the handwheel 322, the drive shaft 321 is rotated, which in turn rotates the gear 35. The gear 35 and the toothed belt 330 on the slide block 33 cooperate to achieve the left and right displacement of the drive block 34, thereby driving the shaking plate 3 to move up and down. This manual method reduces production costs, and manual operation is sufficient in case of material blockage.

[0021] The above description is merely a preferred embodiment of this utility model. The protection scope of this utility model is not limited to the above embodiments. All technical solutions falling within the scope of this utility model's concept are protected. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of this utility model should also be considered within the protection scope of this utility model.
