Description

Technical Field

[0001] This utility model relates to the field of weighing mechanism technology, specifically to a quantitative weighing mechanism for solder production. Background Technology

[0002] Solder production refers to the process of manufacturing low-temperature molten alloy materials for metal bonding through precise ingredient mixing, melting and alloying, and shaping. Solder bars are formed by casting and cooling, solder wires need to be rolled, stretched, and infused with flux cores, and solder paste requires mixing atomized alloy powder with flux paste. Strict quality control is required throughout the production process, ultimately producing solder bars (wave soldering), solder wires (manual soldering), or solder paste (SMT mounting) to meet the requirements of conductive and strong connections in electronic soldering.

[0003] Chinese utility model patent CN217016232U discloses a solder quantitative feeding mixer, which includes "a mixing tank is provided on the carrier plate, a through hole is provided in the middle of the carrier plate, a discharge pipe connected to the mixing tank is passed through the through hole, a solenoid valve is provided on the discharge pipe, a receiving tank is provided below the discharge pipe, and a weighing platform is provided at the bottom of the receiving tank"; however, in the solder production process, the ratio of raw materials is very critical, especially the quantity of some important materials, which often affects the solder performance. When the mixer of this device is used for production, manual weighing and feeding is easy to produce errors and is slow. Utility Model Content

[0004] The purpose of this invention is to provide a quantitative weighing mechanism for solder production to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a quantitative weighing mechanism for solder production, comprising a device frame, an internal stirring device, and an upper part of the device frame; the device frame includes a stirring tank, the upper end of which has a quantitative feeding port; the stirring device includes a drive motor, a transmission rod rotatably mounted on the front end of the drive motor, and a stirring blade fixedly mounted on the outer surface of the transmission rod; the quantitative feeding structure includes a mounting frame, both sides of the inner wall of the mounting frame have sliding grooves, a connecting pipe is fixedly mounted on the upper end of the mounting frame, a storage funnel is inserted into the upper end of the connecting pipe, a sliding plate is slidably mounted inside the mounting frame, and a measuring tube is fixedly mounted on the lower end of the sliding plate, the connecting pipe having the same inner diameter as the measuring tube.

[0006] The beneficial effects of this utility model are as follows: By adding sufficient solder material into the storage funnel, the material flows into the measuring tube through the connecting pipe. When the measuring tube is full, push the handle to move the sliding plate and the measuring tube to the outlet. At this time, the cover plate opens due to gravity, and the material inside the measuring tube falls into the mixing tank for stirring. This device can quantitatively add various materials during use, eliminating the need for manual proportioning of the amount of material to be stirred each time. Only a measuring tube of the corresponding size needs to be set.

[0007] To ensure the stability of the mixing tank during operation: The mixing tank is further configured such that: four support legs are fixedly installed at the lower end of the mixing tank; a first feed inlet is fixedly installed on one side of the mixing tank; and a bearing is rotatably installed on one side of the mixing tank.

[0008] By adopting the above technical solution and installing bearings, the stability of the mixing tank will not be affected when the agitator is driven.

[0009] To enable the release of the produced raw materials: The mixing tank is further configured such that a discharge port is fixedly installed at the lower end of the mixing tank, and a discharge plate is inserted into the discharge port.

[0010] By adopting the above technical solution, the unloading plate is inserted into the discharge port during processing to prevent the raw material from flowing out. When production is completed, the unloading plate is pulled out to release the solder.

[0011] To achieve the effect of quick replacement of the measuring tube: The mounting frame is further configured such that a baffle is bolted to one side of the mounting frame, a connecting plate is fixedly mounted to one side of the measuring tube, and a handle is fixedly mounted to one side of the connecting plate.

[0012] By adopting the above technical solution, the bolts used to fix the baffle can be loosened, the baffle can be removed, the sliding plate can be slid out, and then a measuring tube of the required size can be installed to meet the production needs of different solders.

[0013] To enable easy opening and closing of the measuring tube: The configuration is further defined as follows: a fixing rod is fixedly installed inside the connecting plate, the fixing rod passes through both sides of the connecting plate, and two movable connecting parts are rotatably installed on the outer surface of the fixing rod. The two movable connecting parts are symmetrically distributed on both sides of the connecting plate, and the same cover plate is fixedly installed on one side of the two movable connecting parts. The cover plate is in contact with the surface of the mounting frame base, and limit rings are fixedly installed on both sides of the fixing rod.

[0014] By adopting the above technical solution, when the handle is pulled back, the base plate of the mounting frame will push the cover plate to cover the measuring tube. The measuring tube will slide to the bottom of the connecting tube. At this time, the measuring tube and the connecting tube are in contact. The raw material inside the storage funnel will flow into the measuring tube. When the measuring tube is full, push the handle to move the measuring tube to the left. At this time, the cover plate will open due to gravity, and the material inside the measuring tube will fall into the mixing tank.

[0015] The parts of the device not covered herein are the same as or can be implemented using existing technologies. Attached Figure Description

[0020] In this embodiment, as Figure 1 and Figure 2 As shown, four support legs 102 are fixedly installed at the lower end of the mixing tank 101, a first feed inlet 103 is fixedly installed on one side of the mixing tank 101, and a bearing 105 is rotatably installed on one side of the mixing tank 101.

[0021] In this embodiment, as Figure 1 and Figure 2 As shown, a discharge port 106 is fixedly installed at the lower end of the mixing tank 101, and a discharge plate 107 is inserted into the discharge port 106.

[0022] In this embodiment, as Figure 1 , Figure 4 and Figure 5 As shown, a baffle 303 is bolted to one side of the mounting frame 301, a connecting plate 308 is fixedly installed on one side of the measuring tube 307, and a handle 309 is fixedly installed on one side of the connecting plate 308.

[0023] In this embodiment, as Figure 1 , Figure 4 and Figure 5 As shown, a fixing rod 310 is fixedly installed inside the connecting plate 308. The fixing rod 310 passes through both sides of the connecting plate 308. Two movable connecting parts 311 are rotatably installed on the outer surface of the fixing rod 310. The two movable connecting parts 311 are symmetrically distributed on both sides of the connecting plate 308.

[0024] The working process of this solder production quantitative weighing mechanism is as follows: First, the user selects a measuring tube 307 of the appropriate capacity and installs it inside the mounting frame 301. A relatively large amount of raw material is added to the mixing tank 101 through the first inlet 103. Then, the required raw material is added to the storage funnel 305. The raw material flows into the measuring tube 307 through the connecting pipe 304. When the measuring tube 307 is full, the raw material stops flowing. At this point, the user grasps the handle 309 and pushes the sliding plate 306 to move the measuring tube 307 forward synchronously. The cover plate 312 opens due to gravity, and the raw material inside the measuring tube 307 flows into the mixing tank. Inside the barrel 101, start the drive motor 201 (model: YVF2-160M-4) to drive the transmission rod 202 and the stirring blade 203 to rotate, mixing the internal raw materials. After completion, pull out the discharge plate 107 and take out the solder from the discharge port 106. Then pull the measuring tube 307 backward. The bottom plate of the mounting frame 301 will press against the cover plate 312 and retract it, covering the bottom of the measuring tube 307. After the measuring tube 307 is reset, the raw materials inside the storage funnel 305 will flow into the measuring tube 307 again. Finally, repeat the above operation.
