Description

Technical Field

[0001] This utility model relates to the field of cable processing equipment technology, and in particular to a cable tinning flux drying machine. Background Technology

[0002] During cable manufacturing, a layer of metallic tin is typically plated onto the outside of the cable. This process involves passing the cable through a high-temperature molten tin bath in a soldering furnace, where the tin is deposited onto the cable. This high-temperature molten tin usually contains flux, such as rosin, organic acids, solvents, and additives. After the cable passes through the molten tin and is plated with metallic tin, flux residue often remains on the tin layer. This flux not only affects the cable's appearance, such as causing "black spots," but also its performance. For example, residual flux can seep into the cable's braided layer, affecting its performance; the rosin resin in the residual flux can reduce the surface insulation resistance of the cable, causing signal interference; and under high-temperature conditions, the residual flux may decompose or carbonize, damaging the cable's protective layer and affecting its stability. In existing technologies, the flux residue after tinning cables is usually removed by air drying. However, the method of removing flux by air drying has the following technical problems: some flux is difficult to evaporate and dry at room temperature, the evaporation rate is slow, and there is still a lot of flux residue after the cable is dried, which has an adverse effect on the quality of the cable. Utility Model Content

[0003] The technical problem this utility model aims to solve is to provide a cable tinning flux dryer, addressing the shortcomings of existing technologies. This flux dryer allows cables to pass sequentially through an inlet guide mechanism, a tunnel furnace inlet, a cable conveying tunnel, a tunnel furnace outlet, and an outlet guide mechanism. Inside the cable conveying tunnel, a heating device heats the cables, causing the residual flux after tinning to evaporate rapidly. As the cables pass through the cable conveying tunnel, they also move through an air outlet cavity. Air blown by a blower passes through a duct and the air outlet cavity, then blows onto the cables within the cavity, removing the evaporated flux. The combined action of the heating device and the blower ensures rapid evaporation and removal of residual flux from the cables, preventing appearance issues such as "black spots," avoiding flux affecting cable performance, reducing potential quality problems, and improving the cable quality pass rate.

[0004] To solve the above-mentioned technical problems, the technical solution of this utility model is: a cable immersion flux drying machine, comprising a frame, a tunnel furnace, an inlet guide mechanism, an outlet guide mechanism, a blower, and an outlet chamber. The tunnel furnace is horizontally installed on the upper end of the frame. Inside the tunnel furnace, a cable conveying tunnel and a heating device are provided. The heating device is located at the rear side of the cable conveying tunnel. One end of the tunnel furnace has a tunnel furnace inlet, and the inlet guide mechanism is installed outside the tunnel furnace inlet. The other end of the tunnel furnace has a tunnel furnace outlet. The guiding mechanism is installed outside the tunnel furnace outlet. The cable can pass through the inlet guiding mechanism, the tunnel furnace inlet, the cable conveying tunnel, the tunnel furnace outlet, and the outlet guiding mechanism in sequence. The cable conveying tunnel has air outlet chambers at both ends, with openings at both ends, allowing the cable to move through. The blower is installed at the lower end of the frame and includes an air inlet and an air outlet. A duct connects the blower's air outlet to the two air outlet chambers, allowing the air blown by the blower to pass through the duct and the air outlet chambers before being blown out.

[0005] As a further explanation of this utility model: Preferably, the air inlet of the blower is connected to an air filter, and the air duct is a "Y"-shaped air duct. The lower end of the "Y"-shaped air duct is connected to the air outlet of the blower, and the upper two ends of the "Y"-shaped air duct are respectively connected to two air outlet chambers.

[0006] Preferably, the tunnel furnace is provided with a cover, which is movably hinged to the rear end of the tunnel furnace, and a handle is provided on the cover.

[0007] Preferably, the inlet guide mechanism includes a first guide rod support, on which a plurality of first guide rods are vertically mounted, and there is a gap between adjacent first guide rods for transmitting and guiding cables; the outlet guide mechanism includes a second guide rod support, on which a plurality of second guide rods are vertically mounted, and there is a gap between adjacent second guide rods for transmitting and guiding cables.

[0008] Preferably, the heating device is an electric heating wire heating device.

[0009] Preferably, the cable tinning flux drying machine further includes a control device, which is installed on the rear end of the frame and electrically connected to the blower and the heating device respectively, for controlling the operation of the blower and the heating device.

[0010] The beneficial effects of this utility model are as follows: This flux dryer allows cables to pass sequentially through the inlet guide mechanism, the tunnel furnace inlet, the cable conveying tunnel, the tunnel furnace outlet, and the outlet guide mechanism. Inside the cable conveying tunnel, the heating device heats the cables, causing the flux remaining after tinning to evaporate rapidly. As the cables pass through the cable conveying tunnel, they can also move through the air outlet cavity. The air blown by the blower passes through the air duct and the air outlet cavity, blowing towards the cables inside the cavity, thus removing the evaporated flux. The combined action of the heating device and the blower rapidly evaporates and removes the residual flux from the cables, preventing appearance problems such as "black spots" and ensuring that flux does not affect cable performance. This reduces potential quality issues and improves the cable quality pass rate. Attached Figure Description

[0014] The structural and working principles of this utility model will be further described in detail below with reference to the accompanying drawings.

[0015] like Figures 1-3 As shown, this utility model is a cable immersion flux drying machine, including a frame 1, a tunnel furnace 2, an inlet guide mechanism 3, an outlet guide mechanism 4, a blower 5, and an outlet chamber 6. The tunnel furnace 2 is horizontally installed on the upper end of the frame 1. The tunnel furnace 2 is provided with a cable conveying tunnel 21 and a heating device 22. The heating device 22 is located on the rear side of the cable conveying tunnel 21. One end of the tunnel furnace 2 is provided with a tunnel furnace inlet 23, and the inlet guide mechanism 3 is installed outside the tunnel furnace inlet 23. The other end of the tunnel furnace 2 is provided with a tunnel furnace outlet 24, and the outlet guide mechanism 4 is installed in the tunnel furnace outlet 6. Outside the tunnel furnace outlet 24, the cable can pass sequentially through the inlet guide mechanism 3, the tunnel furnace inlet 23, the cable conveying tunnel 21, the tunnel furnace outlet 24, and the outlet guide mechanism 4; the cable conveying tunnel 21 is provided with air outlet chambers 6 at both ends, and the air outlet chambers 6 are open at both ends, allowing the cable to move through the air outlet chambers 6. The blower 5 is installed at the lower end of the frame 1. The blower 5 includes an air inlet 51 and an air outlet 52. The air outlet 52 of the blower 5 is connected to the two air outlet chambers 6 by a guide pipe 7, and the air blown by the blower 5 can be blown out through the guide pipe 7 and the air outlet chambers 6.

[0016] In the operation of this utility model, the cable first passes through a tin-immersion furnace, the structure of which is described in the applicant's patent ZL202222880115.7. After tin immersion, the cable is coated with a layer of metallic tin. Then, the cable continues to pass through the cable tin-immersion flux drying machine of this utility model. The cable passes sequentially through the inlet guide mechanism 3, the tunnel furnace inlet 23, the cable conveying tunnel 21, the tunnel furnace outlet 24, and the outlet guide mechanism 4. Inside the cable conveying tunnel, the heating device can heat the cable to evaporate the flux remaining after tin immersion. As the cable passes through the cable conveying tunnel 21, it can also move through the two air outlet chambers 6. The air blown by the blower 5 can be blown out through the air guide pipe 7 and the air outlet chambers 6, and blown towards the cable inside the air outlet chambers 6, so that the flux evaporated on the cable is blown away. Under the combined action of the heating device 22 and the blower 5, the flux remaining on the cable can be quickly evaporated and blown away. Therefore, this utility model can quickly eliminate residual flux on the cable, avoid appearance problems such as "black spots" on the cable, prevent flux on the cable from affecting the cable performance, reduce quality risks, and improve the cable quality pass rate.

[0017] like Figure 1 and Figure 2 As shown, the air inlet 51 of the blower 5 is connected to an air filter 8, which can filter out impurities in the air and prevent impurities from sticking to the solder layer of the cable when blown towards it. The air guide duct 7 is a "Y"-shaped air guide duct 7. The lower end of the "Y"-shaped air guide duct 7 is connected to the air outlet 52 of the blower 5, and the upper two ends of the "Y"-shaped air guide duct 7 are respectively connected to two air outlet chambers 6. By using the "Y"-shaped air guide duct 7, one blower 5 can blow air into two air outlet chambers 6. The inner wall of the air outlet chamber 6 is provided with multiple air outlet holes, which can blow air onto the cable passing through the air outlet chamber.

[0018] like Figures 1-3 As shown, a cover 25 is provided on the tunnel furnace 2, and the cover 25 is hinged to the rear end of the tunnel furnace 2. A handle 26 is provided on the cover 25. The cover 25 has two advantages: firstly, it facilitates the manual passage of cables through the cable conveying tunnel 21 and the air outlet 6 by the staff during the initial debugging of the dryer and the cable threading; secondly, it facilitates the staff to check the cable passing status in real time during the operation of the cable tinning flux dryer.

[0019] like Figure 1 and Figure 2As shown, the inlet guide mechanism 3 includes a first guide rod support 31, on which a plurality of first guide rods 32 are vertically mounted, with gaps between adjacent first guide rods 32 for transmitting and guiding cables; the outlet guide mechanism 4 includes a second guide rod support 41, on which a plurality of second guide rods 42 are vertically mounted, with gaps between adjacent second guide rods 42 for transmitting and guiding cables. In this embodiment, four first guide rods 32 and four second guide rods 42 are provided, enabling the transmission and guidance of three cables at a time.

[0020] like Figure 3 As shown, in a preferred embodiment of this utility model, the heating device 22 is an electric heating wire heating device 22.

[0021] like Figure 1 and Figure 2 As shown, the cable tinning flux drying machine also includes a control device 9, which is installed on the rear end of the frame 1. The control device 9 is electrically connected to the blower 5 and the heating device 22 respectively, and is used to control the operation of the blower 5 and the heating device 22. The control device 9 is equipped with a power-on button, a power-off button, an emergency stop button, and buttons for adjusting the blower speed and heating temperature.
