This invention presents a water-cooled sanding table that uniquely integrates a cooling and thermal energy reclamation system. It features a motor-driven sanding belt, a compressor-regulated cooling system with a water tank, evaporator, and condensing coils, alongside an aluminum plate for direct heat transfer from the sanding process. This setup not only prevents heat damage to both workpiece and sanding belt, allowing for higher speed operations without damage, but also captures and repurposes the generated thermal energy. The expelled heat can be utilized for heating spaces or water, showcasing the invention's contribution to energy efficiency and sustainability. This system's ability to enhance processing quality while conservatively managing energy exemplifies a significant advancement in the field.

A speed-adjustable belt-disc sander is provided. The speed-adjustable belt-disc sander includes an electric motor, a first pitch adjustable pulley driven by the electric motor, a second pitch adjustable pulley driven by the first pitch adjustable pulley, a v-belt connecting the first pitch adjustable pulley and the second pitch adjustable pulley, a first pulley driven by the second pitch adjustable pulley, a second pulley driven by the first pulley, a belt sander assembly driven by the second pulley, and a speed adjusting device designed to control an effective belt diameter of the second pitch adjustable pulley, thereby controlling the speed of the belt sander assembly.

A platen apparatus includes a housing having multiple vents; a turbine wheel rotatably attached to a rear section of the housing, the wheel having a circular body and a circumferential face without a coating thereon, the body includes vanes, each vane being a hole which extends through the body from one side to an opposing side of the wheel; a support belt engaged in tension about the circumferential face of the wheel; and the rear section of the housing is at least partially open so that a portion of the circumferential face of the wheel is exposed outside the housing. The vanes are arranged adjacent to the vents, and each provide a flow channel through which air is drawn in from a first side of the housing through the wheel body and released at a second, opposite side of the housing.

A conveyor platform structure includes a platform having a first coupling portion and a second coupling portion respectively disposed on its two side edges adjacent to the front side and the rear side thereof. A driven shaft assembly is pivotally connected to one end of two adjustable extension units, while the other ends of the two adjustable extension units are connected to the first coupling portion of the platform. A driving shaft assembly is pivotally connected to one end of two fixed extension plates, while the other ends of the two fixed extension plates are connected to the second coupling portion of the platform. A conveyor belt is installed between the driven shaft assembly and the driving shaft assembly. The components of the adjustable extension units are simplified to achieve the effect of reducing manufacturing costs.

A polishing system includes a robotic polishing assembly, a belt removal assembly, and a controller. The robotic polishing assembly includes an end effector. The end effector includes a polishing arm, a motor, and a tool head. The tool head extends along a lengthwise axis between and to an inner end and a tip end. The tool head includes a belt tensioner, a roller, and an abrasive belt. The belt tensioner is configured to bias the tip end outward from the inner end. The abrasive belt is disposed on the motor and the roller. The belt removal assembly includes a first lateral arm, a second lateral arm, and a back stop. The controller includes a processor in communication with a non-transitory memory storing instructions, which instructions when executed by the processor, cause the processor to: identify an end-of-life condition is present for the abrasive belt and remove the abrasive belt from the tool head.
