Description

Technical Field

[0001] This utility model relates to the field of electric welding machine technology, and in particular to a feeding mechanism and its fixed electric welding machine. Background Technology

[0002] A welding machine is essentially a transformer with a drooping output characteristic, converting 220V and 380V AC power into low-voltage DC power. Welding machines are generally classified into two types according to the type of output power: AC power and DC power. A DC welding machine can also be considered a high-power rectifier with positive and negative terminals. When AC power is input, it is transformed by the transformer and then rectified by the rectifier, resulting in a power output with a drooping output characteristic. A huge voltage change occurs when the output terminal is switched on and off. When the two poles are momentarily short-circuited, an electric arc is ignited. The generated electric arc is used to melt the welding rod and welding material, and after cooling, they are joined together.

[0003] Currently, welding machines are divided into two types based on their working position: one is mobile, which is used for small welding machines and is easy to move and carry; the other is stationary, which is suitable for large welding machines. For stationary welding machines, current welding machines do not have an auxiliary feeding mechanism, which makes it difficult to feed heavier welding materials and also prevents the welding site from being pre-cleaned, so improvements are needed. Utility Model Content

[0004] The purpose of this utility model is to provide a feeding mechanism and a fixing welding machine thereof to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a feeding mechanism, including a base, a lifting platform, a bottom plate, and a cleaning roller. The lifting platform is movably arranged on one side of the top of the base. A top groove is opened on one side of the lifting platform. Multiple rotating gears are movably arranged inside the top groove. A horizontal plate is connected to the top of the rotating gears through a support rod. A vertical plate is connected to the top side of the horizontal plate. A cleaning roller is installed on the outside of the vertical plate through a rotating rod, and the cleaning roller is located at the top of the lifting platform.

[0006] Preferably, the bottom end of the base is provided with a support leg, and the side of the lifting platform slides on the support leg.

[0007] Preferably, the bottom of the base is equipped with a base plate via support legs, and a lifting cylinder is installed at the center of the bottom end of the base plate. The output end of the lifting cylinder is connected to the center of the bottom end of the lifting platform.

[0008] Preferably, an outer casing is provided on the inner side of the vertical plate, and a transmission gear one and a transmission gear two that mesh with each other are installed inside the outer casing, and the axis of the transmission gear one is connected to the rotating rod at one end of the cleaning roller.

[0009] Preferably, a drive motor is mounted on the outer side of the housing, and the output end of the drive motor is connected to the axis of the transmission gear two via an output rod.

[0010] Preferably, an internal toothed plate is movably arranged inside the top groove, and the internal toothed plate is meshed with multiple rotating toothed discs. A side-push cylinder is arranged on the side of the base, and the output end of the side-push cylinder is connected to one end of the internal toothed plate.

[0011] Another objective of this utility model is to provide a fixed welding machine, including a welding machine body, wherein the welding machine body is disposed at the top of the base.

[0012] The technical effects and advantages of this utility model are as follows: This application features a lifting platform on the side of the spot welding machine, which can be pushed by a lifting cylinder. During loading and feeding, the lifting platform can descend to the bottom of the base, thus assisting in loading and feeding, saving time and effort. Multiple cleaning rollers are installed on the side of the base. When the lifting platform lifts the welding material onto the base, the welding material comes into contact with the cleaning rollers. The cleaning rollers then rotate under the drive of the motor, continuously rubbing against the welding material to remove dust and impurities from the surface of the welding material. This makes it less prone to false welds during welding, resulting in higher welding quality. After cleaning, when welding begins, the rotating toothed disc at the bottom of the cleaning roller can rotate, thereby adjusting the direction of the cleaning roller. The cleaning roller discharges material in a front-to-back manner, without affecting the normal welding of the workpiece. Attached Figure Description

[0018] This utility model provides, for example Figure 1-3 The feeding mechanism shown includes a base 1, a lifting platform 2, a base plate 3, and a cleaning roller 8. The lifting platform 2 is movably arranged on one side of the top of the base 1. A top groove 5 is opened on one side of the lifting platform 2. Multiple rotating gears 9 are movably arranged inside the top groove 5. The top of the rotating gears 9 is connected to a horizontal plate 10 through a support rod. A vertical plate 11 is connected to the top side of the horizontal plate 10.

[0019] like Figure 1 , Figure 2 and Figure 3 As shown, this utility model discloses a feeding mechanism and its fixed welding machine. Specifically, the bottom end of the base 1 is provided with a support leg, and the side of the lifting platform 2 slides on the support leg. The support leg and the base 1 are integrally formed.

[0020] like Figure 1 , Figure 2 and Figure 3 As shown, this utility model discloses a feeding mechanism and its fixed welding machine. Specifically, a base plate 3 is installed on the bottom of the base 1 via support legs. A lifting cylinder 4 is installed at the center of the bottom end of the base plate 3. The output end of the lifting cylinder 4 is connected to the middle of the bottom end of the lifting platform 2. The lifting cylinder 4 is a commercially available device known to those skilled in the art. Here, we are only using it without making any structural or functional improvements, and we will not elaborate further.

[0021] like Figure 1 , Figure 2 and Figure 3 As shown, this utility model discloses a feeding mechanism and its fixed welding machine. Specifically, an outer shell 12 is provided on the inner side of the vertical plate 11. Inside the outer shell 12, a transmission gear 14 and a transmission gear 15 that mesh with each other are installed. The shaft of the transmission gear 14 is connected to the rotating rod at one end of the cleaning roller 8. Both the transmission gear 14 and the transmission gear 15 are metal gears. The transmission gear 14 and the transmission gear 15 are commercially available devices known to those skilled in the art. Here, we are only using them without making any structural or functional improvements. We will not elaborate further here.

[0022] like Figure 1 , Figure 2 and Figure 3 As shown, this utility model discloses a feeding mechanism and its fixed welding machine. Specifically, a drive motor 13 is installed on the outside of the outer shell 12, and the output end of the drive motor 13 is connected to the shaft of the transmission gear 15 through the output rod. The drive motor 13 is a commercially available device known to those skilled in the art. Here, we are only using it without making any structural or functional improvements, and we will not elaborate further.

[0023] like Figure 1 , Figure 2 and Figure 3 As shown, this utility model discloses a feeding mechanism and its fixed welding machine. Specifically, an internal toothed plate 7 is movably arranged inside the top groove 5, and the internal toothed plate 7 is meshed with multiple rotating toothed discs 9. A side-push cylinder 6 is arranged on the side of the base 1. The output end of the side-push cylinder 6 is connected to one end of the internal toothed plate 7. The side-push cylinder 6 is a commercially available device known to those skilled in the art. Here, we are only using it without making any structural or functional improvements. We will not elaborate further here. The side-push cylinder 6 moves the internal toothed plate 7 inside the top groove 5. When the internal toothed plate 7 moves, it meshes with multiple rotating toothed discs 9, thereby allowing the rotating toothed discs 9 at the bottom of the cleaning roller 8 to rotate, thereby driving the cleaning roller 8 to adjust its direction.

[0024] The working principle of this utility model is as follows: During welding, the material is first loaded. Under the action of the lifting cylinder 4, the lifting platform 2 descends to the bottom of the base 1. Then, the workpiece to be welded is placed on the lifting platform 2. The lifting cylinder 4 is activated again, and the lifting platform 2 begins to rise under the push of the cylinder until it rises to the same platform as the base 1. This makes loading more time-saving and labor-saving. Multiple cleaning rollers 8 are set on the side of the base 1. When the lifting platform 2 lifts the workpiece to be welded onto the base 1, the workpiece can contact the cleaning rollers 8. Then, the cleaning rollers 8, driven by the drive motor 13, are driven by the transmission gear 14 and the transmission gear 15 and begin to rotate. The cleaning rollers 8 continuously contact the welding material. Friction is applied to remove dust and impurities from the surface of the welding material, making it less prone to false welds and resulting in higher welding quality. After the welding material is cleaned, the cleaning roller 8 needs to be withdrawn before welding begins. This can be achieved by moving the inner toothed plate 7 inside the top groove 5 using the side push cylinder 6. When the inner toothed plate 7 moves, it meshes with multiple rotating toothed discs 9, causing the rotating toothed discs 9 at the bottom of the cleaning roller 8 to rotate. This, in turn, causes the cleaning roller 8 to change its orientation from horizontal to vertical and is positioned on the top side of the base 1. The multiple cleaning rollers 8 are arranged in a front-to-back arrangement, which does not affect the normal welding of the workpiece. Then, the workpiece is welded by the welding machine body 16. After welding, the material is fed back by the lifting platform 2.
