Description

Technical Field

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

[0002] Flux helps to lower welding temperature, improve weld quality, prevent oxidation and corrosion, and also enhance the fluidity of solder and reduce the surface tension of welding. The raw materials for making flux include alcohol, resin, phenolic compounds, ethylene glycol, castor oil, rosin, paraffin, etc. During the production and processing of flux, the raw materials need to be added through feeding equipment to ensure production efficiency.

[0003] According to a publicly disclosed automatic feeding device for flux production (publication number: CN211197918U), in the above application, a user puts rosin raw materials into a raw material box, and then heats and melts the rosin raw materials through a heating base, and the melted rosin enters the liquid infusion pipe along the liquid inlet pipe through a feeding pump, and impurities in the rosin liquid are filtered through a filter box, and the filtered rosin liquid flows into a storage funnel from a second discharge valve through a liquid outlet pipe. By setting a weighing sensor, when the weight of the rosin raw materials in the storage funnel reaches a specified weight, the second discharge valve is controlled to be closed, and the first discharge valve is opened at the same time, so that the rosin raw materials flow into the guide trough and are fed through the guide trough.

[0004] However, in actual use of the above equipment, the rosin raw material is heated and melted, and then weighed before adding to ensure the effect of adding. The rosin raw material is rosin powder, which will cause agglomeration due to improper storage and contact with water vapor in the air. At the same time, the rosin powder needs to be fused with alcohol to make rosin water as a raw material for addition. The agglomerated rosin powder will reduce the speed of fusion with alcohol, thereby reducing the efficiency of adding. In view of this, we proposed an automatic feeding device. Utility Model Content

[0005] The purpose of the utility model is to provide an automatic feeding device to solve the problems raised in the above background technology.

[0009] A pressure roller is fixedly connected to one end of the rotating shaft away from the mounting groove, a sieve plate is arranged at the bottom of the pressure roller, the reciprocating screw is connected to an auxiliary rod through a transmission belt, and a stirring shaft is fixedly connected to the surface of the auxiliary rod.

[0010] Preferably, the surface of the pressing roller is in contact with the upper surface of the sieve plate, and the surface of the moving block is in contact with the inner wall of the material storage shell.

[0011] Preferably, the side of the rotating block away from the rotating shaft is arranged in an inclined shape, and the side of the contact block close to the rotating block is arranged in an inclined shape.

[0012] Preferably, the end of the auxiliary rod is rotatably connected to the inner wall of the storage shell, and the auxiliary rod is located at the lower end of the storage shell, driving the alcohol to flow and merge with the rosin powder.

[0013] Preferably, a protrusion is fixedly connected to the surface of the rotating block, and the outer surface of the protrusion is matched with the inner surface of the embedding groove.

[0014] Preferably, the embedding groove is provided on the surface of the contact block, and the embedding groove is convenient for fitting with the protrusion.

[0015] Compared with the prior art, the utility model provides an automatic feeding device, which has the following beneficial effects:

[0016] 1. The automatic feeding equipment is provided with a valve to introduce alcohol into the liquid inlet pipe and then put it into the storage shell. The rosin powder is put through the screening of the sieve plate so that the rosin powder with smaller particles can contact with the alcohol for easy fusion. The motor drives the reciprocating screw to rotate the auxiliary rod through the transmission belt, so that the stirring shaft stirs the rosin powder and the alcohol to ensure the fusion effect of the two. The moving block drives the pressure roller to move left and right following the rotation of the reciprocating screw. When the pressure roller moves toward the left side, the contact block contacts the rounded corner of the rotating block so that the resistance of the positive rotation of the rotating shaft becomes smaller to crush the agglomerated rosin powder. When the pressure roller moves toward the right side, the inclined surface of the contact block and the rotating block increases the resistance of the reverse rotation of the rotating shaft to flatten the rosin powder, prevent accumulation from reducing the efficiency of fusion with alcohol, and then make the rosin and alcohol fully fused for feeding when the solder resist is produced, avoid the agglomeration of rosin powder and the influence of rosin water on the feeding, and improve the stability of feeding.

[0017] 2. The automatic feeding equipment, by setting the cooperation between the convex block and the embedded groove, ensures that when the pressure roller moves toward the right, the resistance between the contact block and the rotating block can be guaranteed, and then the pressure roller can flatten the rosin powder when moving on the surface of the screen plate, thereby ensuring that the rosin powder contacts the screen plate evenly and improving the efficiency of the rosin powder falling and fusing with alcohol.

[0025] In one embodiment of the utility model, the surface of the pressure roller 15 is attached to the upper surface of the screen plate 16, the surface of the moving block 11 is attached to the inner wall of the material storage shell 6, the side of the rotating block 14 away from the rotating shaft 21 is arranged in an inclined shape, the side of the contact block 13 close to the rotating block 14 is arranged in an inclined shape, the end of the auxiliary rod 17 is rotatably connected to the inner wall of the material storage shell 6, the surface of the rotating block 14 is fixedly connected with a protrusion 19, the outer surface of the protrusion 19 is adapted to the inner surface of the embedding groove 20, the embedding groove 20 is opened on the surface of the contact block 13, and a feeding tank is arranged on the top of the weighing sensor 3, and a liquid pump A 2 extracts the raw material from the inside of the storage shell 6 and discharges it to the inside of the feeding tank through a pipeline for weighing. After the weighing reaches the target, the raw material is discharged to the feeding tank 5 through a liquid pump 2 4 for feeding. A feed port is provided on the top of the storage shell 6, and a sealing cover is provided on the top of the feed port. The liquid inlet pipe 7 is convenient for introducing alcohol by connecting to an external pipeline. The valve 8 controls the flow of alcohol into the storage shell 6. The contact block 13 and the rotating block 14 are inclined and the shorter end is rounded. The protrusion 19 is fixedly installed on the side of the rotating block 14 away from the rounded corner, and the embedded groove 20 is provided on the side of the contact block 13 away from the rounded corner.

[0026] In the utility model, when the soldering flux needs to be added with raw materials, the rosin powder is put into the storage shell 6, the liquid inlet pipe 7 introduces alcohol through the valve 8, the rosin powder will fall on the sieve plate 16, and the rosin powder that can pass through the sieve hole will contact with the alcohol, the motor 9 is turned on, and the motor 9 drives the reciprocating screw 10 to rotate.

At the same time, the pressure roller 15 encounters the agglomerated rosin powder on the surface of the sieve plate 16, and the pressure roller 15 moves toward the left side. When moving, the pressure roller 15 contacts the raised rosin powder, which will drive the rotating shaft 21 to rotate forward inside the installation groove 12, so that the rotating block 14 rotates with the rotating shaft 21. The rounded corners of the rotating block 14 and the contact block 13 make the resistance to the forward rotation of the rotating shaft 21 smaller, thereby crushing the raised rosin powder. When the pressure roller 15 moves toward the right side, the rotating block 14 and the contact block 13 fit each other, so that the resistance to the rotation of the rotating shaft 21 inside the installation groove 12 increases. At this time, the protrusion 19 will be inserted into the embedded groove 20, making it impossible for the pressure roller 15 to rotate. The pressure roller 15 flattens the rosin powder on the surface of the screen plate 16 to prevent the rosin powder from accumulating at one place on the screen plate 16 and causing the falling speed to decrease, thereby ensuring the efficiency of feeding.
