You mean while playing a record?.... I shall tell you a secret, eveytime you needle plays a record, it melts the vinyl a bit , just like that you can ice skate and melt the ice through the pressure.
But if you smell your vinyl then your needle is installed very wrong.
And needs to be replaced.

if you smell your platter, without playing a song , you have to watch if. it spins at normal speed without variation, then you can remove the platter and give your bearing one drup oil. But that ain't the problem.
you have to smell the motorunit, since it's a cheap turntable and ain't having good components, but start with following that link i gave you and you only have a motor with some electronics , a belt
and a bearing with a platter and in your case a builtin usb and phono-amplifier which are useless, because the quality is way too low. not much can go broke.
