Description

Technical Field

[0001] This utility model relates to the field of tin-melting heating devices, specifically a tin-melting heating device for tin plating of copper strips. Background Technology

[0002] Each existing copper strip tinning machine has a hot-dip tinning device. The melting tank of the hot-dip tinning device is a cuboid, and the heating tubes heat the outside of the melting tank, which can tin-plate multiple copper strips at the same time.

[0003] The hot-dip tinning equipment of this structure has the following disadvantages in use: the melting tank is short, the copper strip travels too short a distance in the melting tank, and the retention time is too short, which makes the preheating time of the copper strip too short when tinning. In addition, when the copper strip separates from the molten tin, the molten tin is affected by the tension and sticks to the surface of the copper strip, resulting in uneven coating thickness of the produced tin-plated copper strip. Summary of the Invention

[0004] Based on this, the purpose of this utility model is to provide a molten tin heating device for tin plating copper strip, so as to solve the technical problem that the preheating time of copper strip during tin plating is too short, and the molten tin liquid adheres to the surface of copper strip due to tension when the copper strip separates from the molten tin, resulting in uneven plating thickness of the produced tin-plated copper strip.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a tin-melting heating device for tin plating copper strip, comprising a heating furnace and a heating box embedded and fixed in the heating furnace. Mounting plates are fixed at both ends of the heating furnace. Grooves are provided on both sides of the top surface of the mounting plates. Mounting rods are fixed between two of the grooves. A tin-scraping mechanism is slidably sleeved between two mounting rods on the same side. A preheating plate is provided on the side wall of the heating box. Heat-conducting frames are fixed on both sides of the top surface of the preheating plate. A heat-conducting plate is elastically arranged between two heat-conducting frames.

[0006] The present invention is further configured such that the heating furnace is equipped with a switch and a display screen, and an electric heating plate connected to the heating box is embedded and fixed inside the heating furnace.

[0007] The present invention is further configured such that sliding rods are fixed on both sides of the top surface of the heat-conducting plate, a first spring is sleeved on the bottom end of the sliding rod, and the top end of the sliding rod is slidably inserted into the heat-conducting frame.

[0008] The present invention is further configured such that a second spring is sleeved at both ends of the mounting rod, and a baffle is threaded onto the mounting rod.

[0009] The present invention is further configured such that the solder scraping mechanism includes a mounting shaft and a cleaning rod rotatably sleeved on the mounting shaft, and both ends of the mounting shaft are slidably sleeved on the mounting rod.

[0010] The present invention is further configured such that both ends of the cleaning rod are provided with protrusions, and a copper strip body is embedded between the two cleaning rods.

[0011] The present invention is further configured such that a positioning rod is fixed at the bottom of the inner wall of the heating box, the copper strip body is tightly connected to the outer wall of the positioning rod, and the copper strip body is positioned below the heat-conducting plate.

[0012] In summary, this utility model has the following beneficial effects: By installing a preheating plate on the heating chamber, the copper strip slides on the top of the preheating plate before tin plating. A first spring on the sliding rod pushes the heat-conducting plate to connect tightly with the copper strip, thus preheating the copper strip. Simultaneously, a positioning rod moves the copper strip to the bottom of the heating chamber, increasing the residence time of the copper strip in the heating chamber and improving the tin plating effect. Furthermore, by fixing mounting plates at both ends of the heating furnace, and fixing mounting rods in grooves at the top of the mounting plates, a second spring pushes two mounting shafts to move towards each other. Simultaneously, a cleaning rod rotating on the mounting shaft scrapes off excess molten tin from the side wall of the copper strip. A baffle rotates on the mounting rod to adjust its position, thereby adjusting the spring force and the squeezing force of the two cleaning rods on the copper strip, preventing molten tin from sticking to the copper strip.

[0018] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0019] A molten tin heating device for tin plating copper strip, such as Figure 1-4 As shown, the device includes a heating furnace 1 and a heating box 4 embedded and fixed in the heating furnace 1. Both ends of the heating furnace 1 are fixed with mounting plates 5. The top surface of the mounting plate 5 is provided with grooves 10 on both sides. The mounting rods 16 are fixed between the two grooves 10. The two mounting rods 16 on the same side are slidably connected with a solder scraping mechanism. The side wall of the heating box 4 is provided with a preheating plate 6. The top surface of the preheating plate 6 is fixed with heat conduction frames 9 on both sides. The heat conduction plate 8 is elastically arranged between the two heat conduction frames 9.

[0020] A switch 2 and a display screen 7 are respectively installed on the heating furnace 1. An electric heating plate 12 connected to the heating box 4 is embedded and fixed in the heating furnace 1. Slide rods 15 are fixed on both sides of the top surface of the heat-conducting plate 8. A first spring 14 is sleeved on the bottom end of the slide rod 15. The top end of the slide rod 15 is slidably inserted into the heat-conducting frame 9. The copper strip body 3 slides on the top of the preheating plate 6 before tin plating. The first spring 14 on the slide rod 15 pushes the heat-conducting plate 8 to connect tightly with the copper strip body 3, so that the preheating plate 6 and the heat-conducting plate 8 preheat the copper strip body 3. At the same time, the positioning rod 13 moves the copper strip body 3 to the bottom of the heating box 4, thereby increasing the residence time of the copper strip body 3 in the heating box 4.

[0021] Furthermore, both ends of the mounting rod 16 are fitted with second springs 17, and a baffle 18 is threaded onto the mounting rod 16. The tin scraping mechanism includes a mounting shaft 20 and a cleaning rod 11 rotatably fitted onto the mounting shaft 20. Both ends of the mounting shaft 20 are slidably fitted onto the mounting rod 16. Both ends of the cleaning rod 11 are provided with protrusions 19, and a copper strip body 3 is embedded between the two cleaning rods 11. A positioning rod 13 is fixed to the bottom of the inner wall of the heating box 4. The copper strip body 3 is tightly connected to the outer wall of the positioning rod 13, and the copper strip body 3 is located below the heat-conducting plate 8. The second spring 17 pushes the two mounting shafts 20 to move towards each other. At the same time, the cleaning rod 11 rotatably fitted onto the mounting shaft 20 scrapes off excess molten tin from the side wall of the copper strip body 3. The baffle 18 rotates on the mounting rod 16 to adjust its position, thereby adjusting the elastic force of the spring and the squeezing force of the two cleaning rods 11 on the copper strip body 3.

[0022] The working principle of this utility model is as follows: During use, the copper strip body 3 is passed through the heat-conducting plate 8, the positioning rod 13, and the cleaning rod 11 in sequence. Molten solder is then placed in the heating box 4 to melt. During the movement of the copper strip, it slides at the top of the preheating plate 6. The first spring 14 on the slide rod 15 pushes the heat-conducting plate 8 to connect tightly with the copper strip body 3, thereby preheating the copper strip body 3 by the preheating plate 6 and the heat-conducting plate 8. At the same time, the positioning rod 13 moves the copper strip body 3 to the bottom of the heating box 4, increasing the residence time of the copper strip body 3 in the heating box 4. The second spring 17 pushes the two mounting shafts 20 to move towards each other. At the same time, the cleaning rod 11, which is rotatably set on the mounting shaft 20, scrapes off the excess molten solder on the side wall of the copper strip body 3. The baffle 18 rotates on the mounting rod 16 to adjust its position, thereby adjusting the elasticity of the spring and the squeezing force of the two cleaning rods 11 on the copper strip body 3, avoiding the situation of molten solder sticking to the copper strip body 3.
