"upper", "lower", "left", "right", and the like are used merely to indicate relative positional relationships, and when the absolute position of the object being described is changed, the relative positional relationships may also be changed accordingly.

To maintain the following description of the embodiments of the present invention clear and concise, a detailed description of known functions and known components of the utility model have been omitted.

As shown in fig. 1-2, a tin surface height sensing device includes a main body 7; the main body 7 comprises a back frame 71, a vertical column 76 vertically fixed on the front side of the back frame 71, two end plates 77 respectively fixed on the upper and lower ends of the vertical column 76, a speed reducing motor 72 fixed on the top of one end plate 77 above, a fixed block 75 and a movable block 78 arranged between the two end plates 77 and distributed up and down, two guide posts 73 vertically inserted between the fixed block 75 and the movable block 78, and a screw 74 vertically inserted and screwed in the fixed block 75; the upper end of the screw 74 is rotatably inserted into an upper end plate 77, the rotating shaft of the speed reducing motor 72 is vertically arranged downwards and is connected with the upper end of the screw 74, and the lower end of the screw 74 is movably connected to a lower end plate 77 downwards through a movable block 78; the movable block 78 is also fixed with a support 79, and the end of the support 79 is also fixed with a floating block 710.

The utility model provides a tin face height sensing device, still includes drain pan 1 and fixes at drain pan 1 top and with the inside top shell 2 that communicates each other of drain pan 1, drain pan 1 and top shell 2 parcel are in the outside of main part 7.

The bottom of the front side of the bottom shell 1 is provided with a notch 11, the supporting frame 79 is movably arranged in the notch 11, and the floating block 710 is arranged on the front side of the bottom shell 1.

A limiting block 711 is further fixed between the screw 74 and the two guide posts 73, and the limiting block 711 is arranged above the fixed block 75.

The front side of the bottom shell 1 is also embedded with a starting switch 4 and a closing switch 5, and the starting switch 4 and the closing switch 5 are both connected with a speed reducing motor 72.

The front side of the bottom shell 1 is also embedded with a power switch 3, and the power switch 3 is connected with a starting switch 4.

An emergency stop switch 6 is further embedded in the front side of the bottom shell 1, and the emergency stop switch 6 is connected with the closing switch 5.

The working principle is as follows: the back frame 71 is fixed on the edge of the opening of the tin bath so that the floating block 710 is positioned above the opening of the tin bath, a position sensor is taken and arranged on the inner wall of the opening of the tin bath and can sense the position of the floating block 710, and finally the power switch 3 and the emergency stop switch 6 are both connected with an external power supply.

The tin block is put into the tin bath and heated to form tin liquid, the height of the tin surface at the moment is close to the opening of the tin bath, and the bottom of the floating block 710 floats on the tin surface and is maintained at a certain height by virtue of the buoyancy of the tin liquid.

The start switch 4 is operated to start the speed reducing motor 72, and then the screw 74 is driven to rotate in the fixed block 75 by the rotating shaft, so that the fixed block 75 is driven to move downwards according to the principle of threaded connection until the bottom of the fixed block 75 is attached to the top of the movable block 78, the fixed block 75 is continuously driven to move downwards to drive the floating block 710 to overcome the buoyancy of the molten tin and slowly immerse the floating block into the molten tin, and when the floating block 710 is completely immersed into the molten tin, the speed reducing motor 72 is stopped.

When the amount of the tin liquid is slowly reduced, the height of the tin surface is slowly reduced, the top of the floating block 710 gradually floats out, the position sensor can sense the floating block 710 and enters a monitoring state, after the top of the floating block 710 is separated from the bottom of the fixed block 75, the position of the floating block 710 also descends for the same distance by virtue of the sliding connection between the movable block 78 and the two guide posts 73 every time the height of the tin surface descends, and the position sensor can sense the position change of the floating block 710 as long as the position of the floating block 710 continuously changes.

When the position sensor senses that the position of the floating block 710 is not moved, the bottom of the floating block 710 is touched with the bottom of the tin bath, and then the tin liquid is used up; then the position sensor can send a signal to an operator to remind the operator to add the tin blocks; if a fault occurs during use, the emergency stop switch 6 can be operated to cut off the power supply.

The utility model can automatically monitor the tin surface height in the tin bath in real time without frequent manual observation, thereby greatly facilitating the use; but also thoroughly avoids the condition that the copper wire can not be coated with tin due to the depletion of the tin liquid, thereby effectively ensuring the continuity of production to achieve the effects of time saving and labor saving.
