The sensor is used to detect the moving distance of the piston rod 220.
Specifically, the piston rod 220 can move downwards and stretch into the stock chest, and the piston rod 220 stops moving after contacting the oxalic acid in the stock chest, and the sensor is used for measuring the moving distance of the piston rod 220. According to the initial distance from the bottom of the stock chest to the bottom of the piston rod 220 and the moving distance of the piston rod 220, whether oxalic acid exists in the stock chest is judged, and the height of the oxalic acid in the stock chest can be converted, so that the amount of the oxalic acid is calculated. For example, the bottom wall of the storage tank has an area S, the initial distance between the bottom wall and the piston rod 220 is H0, and when the piston rod 220 moves towards the storage tank by a distance H2 and then presses the oxalic acid to stop moving, the height of the oxalic acid in the storage tank is H0-H1, and the volume is S x (H0-H1). The amount of the oxalic acid can be used for controlling the amount of the oxalic acid entering the degreasing furnace after the amount of the oxalic acid is calculated, so that the workpiece in the degreasing furnace is completely degreased, and the large waste of the oxalic acid is avoided.

Specifically, the two ends of the piston rod 220 are located outside the cylinder body 210, i.e., the driving cylinder 200 is a double-headed driving cylinder. The sliding rod 320 of the displacement sensor 300 abuts against one end of the piston rod 220 far away from the base 100, so that the piston rod 220 moves, and the elastic member can push the sliding rod 320 to move, thereby detecting the moving distance of the piston rod 220, and the displacement sensor has a simple structure and low cost.

In particular, the measuring block 222 can be replaced according to the size of the magazine, so that the size and shape of the measuring block 222 is adapted to the size and shape of the magazine. Furthermore, it will be appreciated that, as the apparatus is operated for a prolonged period of time, there may be a slight offset in the relative position of the measuring block 222 and the magazine, resulting in the measuring block 222 colliding with the side walls of the magazine and wearing away as the measuring block 222 moves downwardly into the magazine. Since the measuring block 222 is detachably connected to the rod 221 in this embodiment, when the measuring block 222 is worn, only the measuring block 222 needs to be replaced, and the whole material detecting device does not need to be replaced, so as to save cost.
