Description

Technical Field

[0001] The utility model relates to the technical field of soldering flux production, in particular to an automatic feeding device. Background Art

[0002] The soldering flux is a chemical substance that can help and promote the soldering process, and also has a protective effect and prevents oxidation reactions. The soldering flux can be divided into solid, liquid and gas. Among them, the liquid soldering flux is a mixture with rosin as the main component, and the rosin resin soldering flux is generally composed of rosin, resin, halogenated activator, additives and organic solvents.

[0003] The patent with publication number CN211197918U discloses an automatic feeding device for flux production. By setting up a raw material box and a heating base, the raw materials in the raw material box can be heated, and then the heated raw materials are pumped into the storage funnel through the pump body. In this process, the raw materials will pass through the filter box to remove impurities in the raw materials, and the feeding amount is measured by a weighing sensor to achieve accurate feeding.

[0004] The above device has the following disadvantages when in use: the melted rosin has poor fluidity, and the device uses many pipes, so the raw materials are easy to adhere to the inner wall of the pipes, which is difficult to clean later. Secondly, the filter box is a closed design, and it is not convenient to clean when the internal filter is blocked. In addition, when heating the raw materials, the raw materials at the bottom of the raw material box melt quickly, and the raw materials at the top melt slowly, which affects the feeding efficiency, so further improvement is needed.

[0024] A plurality of mounting rods 15 are fixed to the lower surface of the bottom plate 1. In this embodiment, the device can be directly mounted and fixed on the top of the feed inlet of the production equipment through the mounting rods 15.

[0025] A feeding port 9 is provided on one side of the top of the heating box 6. Through the feeding port 9, the rosin raw material can be added into the heating box 6 inside.

[0026] The stirring assembly 7 includes a first motor 71 fixed to the top of the heating box 6. The bottom driving end of the first motor 71 is fixedly connected to a vertical shaft 72. A plurality of stirring rods 73 are fixed to the surface of the vertical shaft 72. An electromagnetic valve is fixed in the middle of the discharge pipe 11.

[0027] The first motor 71 of the stirring assembly 7 drives the vertical shaft 72 and the stirring rod 73 to rotate inside the heating box 6, so that the raw materials can be stirred, thereby accelerating the melting of the raw materials and improving the feeding efficiency.

[0028] The electromagnetic valve and the pressure sensor 10 are both electrically connected to the control cabinet 16 .

[0029] The amount of raw materials inside the heating box 6 can be monitored by the pressure sensor 10. When the electromagnetic valve is opened and the raw materials are discharged from the discharge pipe 11, the pressure sensor 10 monitors the amount of the discharged materials, and the control cabinet 16 can control the opening and closing of the electromagnetic valve.

[0032] Working principle: first add raw materials into the heating box 6 from the feeding port 9, then start the first motor 71 and the electric heating plate 8 to heat and stir the raw materials. When the raw materials are completely melted, the electromagnetic valve on the feeding pipe 11 is opened through the control cabinet 16. When the feeding amount reaches the set value, the control cabinet 16 controls the electromagnetic valve to close. During the feeding process, the second motor 131 drives the elbow 12 to rotate, so the raw materials discharged from the feeding pipe 11 will be dispersed on the surface of the filter 142 along the elbow 12, and the raw materials will be filtered through the filter 142. The filtered raw materials are discharged from the bottom of the filter bucket 141 and enter the production equipment. Since the top of the filter component 14 of the device is open, it is simpler and easier in the subsequent cleaning process.
