Abstract

An automatic tin-adding machine for adding a plurality of tin rods to a molten tin tank comprises a base, two transmission shafts, at least one first flexible transmission member, a plurality of tin rod carrying members, a tin stock detector, a drive and a circuit control system. The base has a tin rod adding opening corresponding to the molten tin tank. The two transmission shafts are pivoted on the base side by side. The at least one first flexible transmission member is sleeved on the two transmission shafts. The tin rod carrying members are fixed to the first flexible transmission member and configured to carry the tin rods. The tin stock detector is configured to detect the stock of tin liquid in the molten tin tank. The drive is connected to one of the transmission shafts. The circuit control system comprises a circuit control unit.

First claim

What is claimed is:

1 . An automatic tin-adding machine for adding a plurality of tin rods to a molten tin tank, comprising:
a base having a tin rod adding opening corresponding to the molten tin tank; two transmission shafts pivoted on the base side by side; at least one first flexible transmission member sleeved on the two transmission shafts; a plurality of tin rod carrying members fixed to the first flexible transmission member and configured to carry the tin rods; a tin stock detector configured to detect the stock of tin liquid in the molten tin tank; a drive connected to one of the transmission shafts; and a circuit control system comprising a circuit control unit electrically connected to the tin stock detector and the drive, wherein when the tin stock detector detects that the stock of tin liquid in the molten tin tank is less than a predetermined stock, the circuit control unit control the drive to drive one of the transmission shafts to rotate for driving the tin rod carrying members move relative to the base along a transmission path to pass over the tin rod adding opening, so that at least one of the tin rods falls from the tin rod adding opening to the molten tin tank.

2 . The automatic tin-adding machine according to claim 1 , further comprising a tin rod support plate between the base and the tin rod carrying member, wherein the tin rod support plate has a spout corresponding to the tin rod adding opening.

3 . The automatic tin-adding machine according to claim 1 , wherein each of the two transmission shafts comprises a axle and at least one first transmission chainring, the first transmission chainring is fixed to the axle while the first flexible transmission member engages with the two first transmission chainrings.

4 . The automatic tin-adding machine according to claim 3 , further comprising a plurality of installation members fixed to the first flexible transmission member, wherein the tin rod carrying member is fixed to the installation member.

5 . The automatic tin-adding machine according to claim 3 , wherein the number of at least one first transmission chainrings is two, the number of the at least one first flexible transmission members is two, the opposite two ends of the tin rod carrying member are fixed to the two first flexible transmission members respectively.

6 . The automatic tin-adding machine according to claim 3 , further comprising a second flexible transmission member, wherein one of the transmission shafts further comprises a second transmission chainring fixed to the axle, the drive comprises a driving motor and a driving chainring, the driving motor has a driving shaft, the driving chainring is fixed to the driving shaft, the second flexible transmission member engages with the driving chainring and the second transmission chainring for making the driving motor drive the two driving shafts to rotate.

7 . The automatic tin-adding machine according to claim 1 , further comprising a top plate installed on one end of the two transmission shafts away from the base.

8 . The automatic tin-adding machine according to claim 1 , wherein the circuit control system further comprises a power indicator unit and an operation indicator unit, the power indicator unit is configured to show the power state of the automatic tin-adding machine, and the operation indicator unit is configured to show the operation state of the automatic tin-adding machine.

9 . The automatic tin-adding machine according to claim 1 , wherein the circuit control system further comprises a function selection unit having an automatic mode and a enforcing mode, when the automatic tin-adding machine is in the automatic mode, the circuit control unit controls the operation of the drive based on the signal of the tin stock detector, and when the automatic tin-adding machine is in the enforcing mode, the circuit control unit controls and forces the drive to operate.

10 . The automatic tin-adding machine according to claim 1 , wherein the circuit control system further comprises a tin rod detection unit configured to detect the stock of the tin rod carrying members.

11 . The automatic tin-adding machine according to claim 1 , wherein the circuit control system further comprises a failure alert unit configured to show the abnormal state of the automatic tin-adding machine.

12 . The automatic tin-adding machine according to claim 1 , wherein the circuit control system further comprises a time control unit configured to control the operation frequency of the drive to be greater than a predetermined value.
