A first synchronous pulley is connected to the motor shaft, and a second synchronous pulley is connected to the synchronous shaft assembly. A belt is fitted around the outside of the first and second synchronous pulleys.

Different speed settings can be adjusted according to the rock hardness, reducing polishing time and improving efficiency.

Description

Technical Field

[0001] This utility model relates to the field of jewelry processing, and in particular to a two-speed variable-speed roller-type rock polishing machine. Background Technology

[0002] A drum-type rock polishing machine is a common type of rock surface treatment equipment, mainly used in geological specimen preparation, building material processing (such as marble and granite polishing), and jewelry and jade processing. Its basic principle is to use the rotation of the drum to cause the rock sample to rub against abrasives (such as silicon carbide, corundum, etc.), thereby achieving surface polishing.

[0003] Despite the widespread use of drum polishers, the following technical problems still exist:

[0004] Polishing efficiency is low and the cycle is long. Traditional drum polishing machines usually require 24 to 72 hours of continuous operation to achieve the ideal smoothness, especially for high-hardness rocks (such as quartzite and granite), which takes even longer.

[0005] Poor polishing uniformity occurs because the rock sample is randomly tumbled inside the drum, resulting in inconsistent polishing levels in different areas. Some areas may be over-polished while others are under-polished. For irregularly shaped rocks (such as flaky shale or basalt with many edges), the polishing effect is even worse, and the sample may even be damaged due to collisions.

[0006] Traditional drum polishing machines are energy-intensive and noisy, relying on high-power motors (typically 2.2~5.5 kW) for drive. Due to low mechanical transmission efficiency, they consume a lot of energy. The continuous collision between the drum and rocks and abrasives generates significant noise (75~90 dB), affecting the working environment.

[0007] In order to solve the problems existing in the background technology, this utility model provides a two-speed variable drum-type rock polishing machine. Utility Model Content

[0008] The purpose of this invention is to address the shortcomings of existing technologies by providing a two-speed variable-speed drum-type rock polishing machine.

[0009] To achieve the above objectives, the present invention adopts the following technical solution:

[0010] A two-speed variable-speed roller-type rock polishing machine includes a main base, an equipment box on one side of the main base, a PCB board, a capacitor and a motor inside the equipment box, a bottom cover on the bottom surface of one side of the equipment box, a two-speed switch on the side of the equipment box, a synchronous shaft assembly located behind the equipment box on the main base, a roller assembly above the synchronous shaft assembly, a first synchronous pulley connected to the motor shaft, a second synchronous pulley connected to the synchronous shaft assembly, and a belt sleeved on the outside of the first and second synchronous pulleys.

[0011] Furthermore, the synchronous shaft assembly includes a long synchronous shaft and a short synchronous shaft, with the end of the long synchronous shaft connected to the center of the second synchronous pulley. Furthermore, both the long and short synchronous shafts are connected to the main body base via shaft brackets.

[0012] Furthermore, the roller assembly includes a metal drum and a rubber drum disposed inside the metal drum, both of which are internal hexagonal drums.

[0013] Furthermore, the roller assembly also includes a metal cap and a rubber cap. The outer edge of one side of the metal barrel has a post, and the outer edge of the rubber barrel, the metal cap, and the rubber cap all have insertion holes. The insertion holes on the outer edge of the rubber barrel, the insertion holes on the rubber cap, and the insertion holes on the metal cap are sequentially inserted into the post, and the end of the post is connected to a female head for fixing.

[0014] Furthermore, the outer periphery of both ends of the metal barrel is provided with rolled edges, and both ends of the long synchronous shaft and the short synchronous shaft are provided with roller frames, with the rolled edges mounted on the roller frames.

[0015] Furthermore, a faceplate is affixed to one side of the equipment box on the main base.

[0016] Furthermore, foot pads are provided on the bottom surface of the main base.

[0017] Furthermore, the transmission ratio of the first pulley and the second pulley is 3.9:1.

[0018] Furthermore, the width of the belt is 5mm.

[0019] The beneficial effects of this utility model are as follows: the inner liner shape is changed to hexagonal, which makes the rock sample form a directional movement during the tumbling process, improving the polishing uniformity; the U-shaped groove synchronous wheel and the leather ring have great structural elasticity, increasing the adjustable space and effectively reducing the noise caused by friction force generated in the transmission; different speed gears can be adjusted according to the rock hardness, reducing polishing time and improving efficiency.
