[0002] A tin furnace refers to a welding tool used in electronic welding, which can melt tin wire into tin water to meet the welding needs. The tin furnace is generally composed of two major parts: a body and a pot body. The body is provided with a control panel and a heating mechanism, and the pot body is mainly used to hold the molten tin. The pot bodies of existing tin furnaces are mostly open. When in use, the objects to be tinned can be directly immersed in the molten tin. This also causes impurities on the objects to be tinned to fall into the molten tin in the pot body. Subsequently, with heating, these impurities will produce a large amount of smoke, affecting the working environment. In order to solve this problem, a part of the molten tin is generally taken out of the pot body for use. However, how to take out the molten tin and make reasonable use of the taken out molten tin without causing waste is a problem that needs to be solved at present. Therefore, it is necessary to propose a tin furnace with a pneumatic tin discharging structure. Utility Model Content

[0023] A spacer ring 3 is fixedly mounted on the tin pot 2. The inner ring of the spacer ring 3 and the outer periphery of the spacer tube 4 are both provided with matching threads, and the two are threadedly connected.

[0024] Through the above technical scheme, the spacer ring 3 is connected to the tin pot 2 by screws, and the two can be disassembled. The spacer tube 4 is threadedly connected to the spacer ring 3, and the two can be easily disassembled. In this way, the spacer tube 4 and the temporary storage pot 5 can be removed for cleaning and maintenance, and the tin bar can also be placed in the tin pot 2.

[0025] A rotating hole is provided on the spacer ring 3, and the tin outlet tube 18 passes through the rotating hole and is rotatably connected to the rotating hole.

[0026] Through the above technical solution, the tin outlet tube 18 can be rotated so that it will not restrict the disassembly of the partition tube 4, and at the same time, the tin liquid can be discharged into the temporary storage pot 5.

[0027] A limiting ring 19 is provided on the spacer cylinder 4 , and the limiting ring 19 is in contact with the top of the spacer ring 3 .

[0028] Through the above technical solution, the limiting ring 19 allows the spacer 4 to be positioned when the spacer ring 3 is connected and installed.

[0029] A heating plate 21 is provided at the bottom of the temporary storage pot 5 .

[0030] Through the above technical solution, the heating plate 21 can continuously heat the tin liquid extracted from the temporary storage pot 5 to prevent it from solidifying.

[0031] A sealing ring 20 is provided at the bottom end of the temporary storage pot 5 , and the sealing ring 20 is in contact with the bottom end of the partition tube 4 .

[0032] Through the above technical solution, the sealing ring 20 allows the temporary storage pot 5 to maintain contact with the partition tube 4, thereby ensuring the sealing of the entire tin pot 2.

[0033] The reverse thrust mechanism includes a support frame 7 fixedly mounted on the partition 4, a slide rod 8 is slidably mounted on the support frame 7, the bottom end of the slide rod 8 is fixedly connected to the bottom inner wall of the temporary storage pot 5, a stop block 9 is arranged at the top of the temporary storage pot 5, a spring 10 is sleeved on the slide rod 8, and the two ends of the spring 10 are in contact with the support frame 7 and the stop block 9 respectively.

[0034] Through the above technical solution, the reverse thrust can limit the temporary storage pot 5, and can also lower the temporary storage pot 5 by pressing with external force, so that the temporary storage pot 5 can be switched between the closed state and the unloading state.

[0035] The air supply mechanism includes a motor 11 and a valve cylinder 14 fixedly installed on one side of the tin furnace body 1. A bent rod 12 is rotatably installed on one side of the tin furnace body 1. One end of the bent rod 12 is fixedly connected to the output shaft of the motor 11. A pull rod 13 is rotatably connected to the bent rod 12. A piston 15 is slidably installed in the valve cylinder 14. One end of the pull rod 13 is hinged to the piston 15. Two one-way valves 16 are arranged on the valve cylinder 14. One end of the air inlet pipe 17 is connected to one of the one-way valves 16.

[0036] Through the above technical solution, the gas supply mechanism can stably deliver gas into the tin pot 2, thereby increasing the air pressure in the tin pot 2, thereby achieving tin discharge by means of air pressure.

[0037] The implementation principle of a tin furnace with a pneumatic tin discharging structure in the embodiment of the present application is:

[0038] Step 1: Before use, remove the spacer 4 from the spacer ring 3, then put the tin material or tin bar to be melted into the tin pot 2, then install the spacer 4, start the tin furnace body 1 to heat the tin pot 2, so as to melt the tin bar, at this time, the bottom end of the tin outlet tube 18 is immersed in the tin liquid;

[0039] The second step: start the air supply mechanism, the motor 11 drives the crankshaft 12 to rotate, thereby pulling the piston 15 through the pull rod 13. During the movement of the piston 15, air is sucked into the valve cylinder 14 through one of the one-way valves 16, and then the sucked air is pushed into the air inlet pipe 17 through the other one-way valve 16, and then the air is transported to the tin pot 2 through the air inlet pipe 17, and this is repeated. When the air pressure in the tin pot 2 becomes high, the tin liquid will be squeezed into the tin outlet pipe 18, and then the tin liquid will be discharged into the temporary storage pot 5 through the tin outlet pipe 18, thereby realizing the removal of the tin liquid, and at this time, the heating plate 21 can continue to heat the tin liquid in the temporary storage pot 5 to prevent it from solidifying. When in use, the material to be tinned can be directly immersed in the temporary storage pot 5;

[0040] The third step: when the remaining tin liquid needs to be recovered and stored after use, the slide bar 8 is pressed by the stop block 9, and the temporary storage pot 5 is driven down while squeezing the spring 10, until the filter hole 6 on the temporary storage pot 5 is offset from the partition tube 4. At this time, the remaining tin liquid in the temporary storage pot 5 will seep through the filter hole 6 and flow back into the tin pot 2. In this process, the filter hole 6 can filter the impurities floating on the surface of the tin liquid.

[0041] The above-mentioned implementation modes are only preferred implementation modes of the present invention, and cannot be used to limit the protection scope of the present invention. Any non-substantial changes and substitutions made by technicians in this field on the basis of the present invention shall fall within the scope of protection required by the present invention.
