Description

Technical Field

[0001] This utility model relates to the field of flux drying technology, and in particular to a flux drying box that prevents dry burning. Background Technology

[0002] Flux is a granular welding material used to provide wettability and protection to the weld joint. It is composed of various chemical components, including resins, activators, fluxes, and flow agents. When flux is exposed to air or stored for a long time, some hygroscopic substances, such as sodium chloride and ammonium chloride, may be present in the flux components or additives. These substances are hygroscopic and will absorb moisture from the surrounding environment. Alternatively, when flux is exposed to a humid environment, they will absorb moisture from the surrounding environment, resulting in a certain amount of water in the flux. Therefore, flux needs to be thoroughly dried in a drying oven before use to avoid affecting the welding process due to damp flux.

[0003] A search revealed a flux drying box published in Chinese Utility Model Patent Publication No. CN106196939B, which describes a method to prevent dry burning of the flux. This method uses a pressure sensor to detect the addition of flux inside the drying box before controlling the motor to rotate. A photoelectric sensor detects the rotation of the drying box before the heating element starts heating, ensuring effective flux drying and preventing dry burning. However, since the flux particles are placed together, they tend to stick together after absorbing moisture. Direct drying would prevent these sticky particles from separating, affecting subsequent welding. Separating the clumps of flux during welding increases welding time. Therefore, a flux drying box that effectively separates the sticky flux is needed. Utility Model Content

[0004] The main objective of this invention is to provide a flux drying oven that prevents dry burning, which can effectively solve the problems in the background art.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0006] A flux drying box for preventing dry burning includes a drying frame and a filter frame. A drying fan is fixedly connected to the inner wall of both the front and back of the drying frame. An inner mesh and an outer mesh are fixedly connected to the inner wall of the drying fan. A mounting bracket is fixedly connected to the inner wall of the filter frame. A filter screen is fixedly connected to the inner wall of the mounting bracket. A support column is fixedly connected to the lower surface of the filter frame. A box body is fixedly connected to the bottom end of the support column.

[0007] In order to provide power for the rotation of the shaft, as a flux drying box to prevent dry burning according to this utility model, a first servo motor is fixedly connected to the lower surface of the mounting bracket, the output end of the first servo motor is fixedly connected to the shaft, and a dividing blade is fixedly connected to the outer surface of the shaft.

[0008] In order to provide power for the rotation of the rotating rod, as a flux drying box to prevent dry burning according to this utility model, a support frame is fixedly connected to the inner wall of the box, and a second servo motor is fixedly connected to one side of the box.

[0009] In order to separate the bonded flux, as a flux drying box to prevent dry burning according to this utility model, the output end of the second servo motor is fixedly connected to a rotating rod, and the outer surface of the rotating rod is fixedly connected to a dividing plate.

[0010] In order to achieve the effect of supporting the box, as a flux drying box for preventing dry burning according to this utility model, the inner bottom wall of the box is fixedly connected with a support rod, and the lower surface of the box is fixedly connected with a support leg.

[0011] In order to achieve the effect of collecting the dried flux, as a flux drying box to prevent dry burning according to this utility model, a heating frame is fixedly connected to the upper surface of the support rod, a heating plate is fixedly connected to the inner bottom wall of the heating frame, and a collection frame is provided on the inner wall of the lower surface of the box.

[0012] To facilitate ventilation, the flux drying box of this utility model, which is designed to prevent dry burning, has baffles fixedly connected to the inner walls of both the front and back sides of the box, and the front of the baffles has ventilation openings.

[0013] In order to facilitate the entry of the flux to be dried into the box, as a flux drying box to prevent dry burning according to this utility model, a top cover is fixedly connected to the upper surface of the box body, and a feed port is fixedly connected to the upper surface of the top cover.

[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0015] 1. This flux drying box for preventing dry burning, through the arrangement of a drying frame, drying fan, inner screen, outer screen, filter frame, mounting bracket, and filter screen, allows a large amount of flux to enter the box from the inlet. The flux first passes through a dividing disc, which is rotated by a rotating rod, initially dispersing the clumps of flux. As the flux falls through the drying frame, the activated drying fan performs initial drying. Afterward, the flux falls onto the filter screen in the filter frame, where a second servo motor drives a rotating shaft, causing the dividing blades to rotate on the filter screen, further breaking up any remaining clumps of flux. The dispersed flux then falls through the filter screen onto the heating plate of the heating frame, and finally rolls from the inclined heating frame into the collection frame. This process effectively disperses the dried flux, facilitating subsequent flux processing and avoiding time wasted on manually dispersing the flux.

[0016] 2. This flux drying oven, designed to prevent dry burning, is equipped with a drying frame, a drying fan, a heating frame, and a heating plate. Both the drying frame and the heating frame are made of high-temperature resistant materials, such as ceramics. Furthermore, the oven employs multi-stage drying to prevent the heating structures from accumulating together. The drying fan and the heating plate concentrate heat within the drying frame and the heating frame, and the heating temperature of both is limited, thus preventing dry burning inside the drying oven.

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] Example 1

[0027] like Figure 1-7 As shown, a flux drying box for preventing dry burning includes a drying frame 1 and a filter frame 5. A drying fan 2 is fixedly connected to the inner wall of the front and back of the drying frame 1. An inner mesh 3 is fixedly connected to the inner wall of the drying fan 2, and an outer mesh 4 is fixedly connected to the inner wall of the drying fan 2. A mounting frame 6 is fixedly connected to the inner wall of the filter frame 5, and a filter screen 7 is fixedly connected to the inner wall of the mounting frame 6. A support column 13 is fixedly connected to the lower surface of the filter frame 5, and a box body 12 is fixedly connected to the bottom end of the support column 13.

[0028] In practical use, the drying chamber mainly consists of four parts: a primary dividing structure composed of a dividing plate 16, a primary drying structure composed of a drying frame 1, an inner mesh 3, an outer mesh 4, a filter frame 5, a mounting bracket 6, and a filter screen 7. The secondary dividing and filtering structure is composed of a dividing plate 16, a primary drying structure composed of a drying frame 1, a secondary dividing and filtering structure composed of a filter frame 5, and a secondary drying structure composed of a heating frame 18. When drying the flux, the first servo motor 8 and the second servo motor 14 are started. A large amount of flux enters the chamber 12 from the inlet 25, first passing through the dividing plate 16. The dividing plate 16 is rotated by the rotating rod 15, which disperses the flux. The flux is initially dispersed as it falls through the drying frame 1 and is dried for the first time by the activated drying fan 2. Afterward, the flux falls onto the filter screen 7 in the filter frame 5. The second servo motor 14 drives the rotating shaft 9 to rotate, causing the dividing blade 10 to rotate on the filter screen 7, breaking up the flux that is still stuck together. The dispersed flux can fall through the filter screen 7 onto the heating plate 19 of the heating frame 18, and finally roll from the inclined heating frame 18 into the collection frame 20. This disperses the dried flux that has gathered together, making subsequent flux work easier and avoiding wasting time on manually dispersing the flux.

[0029] In this embodiment, a first servo motor 8 is fixedly connected to the lower surface of the mounting bracket 6, a rotating shaft 9 is fixedly connected to the output end of the first servo motor 8, and a dividing blade 10 is fixedly connected to the outer surface of the rotating shaft 9.

[0030] In practical use, the first servo motor 8 provides power for the rotation of the shaft 9.

[0031] In this embodiment, a support frame 11 is fixedly connected to the inner wall of the housing 12, and a second servo motor 14 is fixedly connected to one side of the housing 12.

[0032] In practical use, the second servo motor 14 provides power for the rotation of the rotating rod 15.

[0033] In this embodiment, a rotating rod 15 is fixedly connected to the output end of the second servo motor 14, and a dividing disk 16 is fixedly connected to the outer surface of the rotating rod 15.

[0034] In practical use, the adhesive flux is separated by the partition disk 16.

[0035] In this embodiment, a support rod 17 is fixedly connected to the inner bottom wall of the box 12, and a support leg 21 is fixedly connected to the lower surface of the box 12.

[0036] In practical use, the support legs 21 are used to support the box 12.

[0037] In this embodiment, a heating frame 18 is fixedly connected to the upper surface of the support rod 17, a heating plate 19 is fixedly connected to the inner bottom wall of the heating frame 18, and a collection frame 20 is provided on the inner wall of the lower surface of the box 12.

[0038] In practical use, the dried flux is collected through the collection box 20.

[0039] In this embodiment, baffles 22 are fixedly connected to the inner walls of the front and back sides of the box 12, and ventilation openings 23 are provided on the front of the baffles 22.

[0040] In practical use, ventilation is conveniently provided through the vent 23.

[0041] In this embodiment, a top cover 24 is fixedly connected to the upper surface of the box 12, and a feed inlet 25 is fixedly connected to the upper surface of the top cover 24.

[0042] In practical use, the feed inlet 25 facilitates the entry of the flux to be dried into the box.

[0043] Working principle: When drying the flux, the first servo motor 8 and the second servo motor 14 are started. A large amount of flux enters the box 12 from the feed port 25. It first passes through the dividing plate 16, which is driven by the rotating rod 15 to rotate, thus dispersing the flux that is gathered together for the first time. When the flux falls from the drying frame 1, it is dried for the first time by the starting drying fan 2. Then the flux falls onto the filter screen 7 in the filter frame 5. The second servo motor 14 drives the rotating shaft 9 to rotate, so that the dividing blade 10 rotates on the filter screen 7, breaking up the flux that is still stuck together. The dispersed flux can fall onto the heating plate 19 of the heating frame 18 through the filter screen 7, and finally rolls into the collection frame 20 from the inclined heating frame 18.
