Description

Technical Field

[0001] This utility model relates to the field of welding wire winding technology, specifically to a reciprocating welding wire rewinding device. Background Technology

[0002] The welding materials used in automatic welding of long-distance pipelines are supplied in reels, mainly 20Kg large reels and 5Kg small reels. In actual construction, in order to save costs and reduce losses, the welding wire from the large reels needs to be transferred to the small reels for welding. There are two previous methods of transfer: one is to manually rotate the welding wire reel for winding, which is inefficient and labor-intensive; the other is to use a combination of mechanical and manual winding, which improves efficiency but results in uneven winding and easy tangling of the welding wire.

[0003] Chinese Patent CN206445027U discloses an automatic wire winding machine, which includes a frame, a fixed plate, a rotating shaft, a winding reel, a movable plate, a moving frame, a motor, and an operating panel. The fixed plate is fixed to the frame, and the rotating shaft is located at the center of the fixed plate. The fixed plate and the movable plate clamp the winding reel onto the rotating shaft. The movable plate is installed or removed via the moving frame. The rotating shaft and the moving frame are driven by different motors, and the operating panel is used to control the motor operation. Although this wire winding machine can achieve automatic wire winding, the winding process is continuous. During winding, the wire initially winds around the middle section of the take-up reel and then winds outwards from the middle. Therefore, the wire tends to accumulate in the middle of the take-up reel, reducing the overall quality of the wire. Utility Model Content

[0004] The main objective of this invention is to provide a reciprocating wire rewinding device that enables the welding wire to be evenly distributed on the spool during the winding process.

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

[0006] A reciprocating welding wire rewinding device includes a base plate, a winding assembly on the base plate, and a guide assembly for guiding the welding wire on the base plate in front of the winding assembly. The guide assembly includes a second motor fixed on the base plate, a reciprocating screw concentrically fixed on the output shaft of the second motor, the reciprocating screw being rotatably connected to the base plate, a connecting sleeve sleeved on the outside of the reciprocating screw, the connecting sleeve, the balls inside the connecting sleeve, and the reciprocating screw forming a ball reciprocating screw pair, a cover body on the top of the base plate, the cover body being fixedly connected to the connecting sleeve, the cover body being slidably connected to the base plate, the sliding direction of the cover body being parallel to the axial direction of the reciprocating screw, a guide member on the upper end of the cover body, the guide member including a support fixed on the cover body, a rotating seat rotatably connected inside the support body, the rotating seat and the support body being connected by a positioning assembly, a support plate fixed on the rotating seat, a groove being provided on the upper end of the support plate, when the rotating seat drives the support plate to rotate to a vertical state, the positioning assembly can position the rotating seat and the support plate.

[0007] Specifically, the winding assembly includes a first motor fixed to the upper end of the base plate, a rotating rod rotatably connected to the base, the rotating rod being concentric with the output shaft of the first motor, the output shaft of the first motor being fixedly connected to the rotating rod, a shaft being concentrically fixed to one end of the rotating rod, a baffle being fixed to the shaft, and a pressure plate being threaded to one end of the shaft.

[0008] Specifically, the rotating rod is rotatably connected to the bearing seat fixed on the base plate via a bearing.

[0009] Specifically, a control box is fixed to the upper end of the base plate. The control box contains a pulse generator, a first driver, and a second driver. Both the first motor and the second motor are servo motors. The pulse generator, the first driver, and the first motor are electrically connected. The pulse generator, the second driver, and the second motor are also electrically connected.

[0010] Specifically, a slide rail is fixed on the base plate, and a slider is slidably mounted on the slide rail, with the slider being fixedly connected to the cover.

[0011] Specifically, the rotating seat and the support are rotatably connected by a pin.

[0012] Specifically, the positioning component includes arc-shaped grooves on both sides of the support, the arc-shaped grooves being concentric with the pin shaft, and circular holes on both sides of the support, the circular holes communicating with the upper end of the arc-shaped grooves. A sliding rod passes through the arc-shaped grooves and the rotating seat, and is slidably connected to the support and the rotating seat. A spring is fitted on the sliding rod, one end of the spring being fixedly connected to the rotating seat, and the other end of the spring being fixedly connected to the sliding rod. Two outer rings are fixed on the sliding rod. When the rotating seat rotates to a vertical state, the outer rings correspond to the circular holes, and under the elastic force of the springs, the outer rings enter the circular holes on one side.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0014] 1. Through the linkage design of the ball reciprocating screw pair and the servo motor, combined with the transverse slide rail guide structure, the guide component drives the welding wire to achieve high-precision reciprocating motion in the axial direction of the spool. This dynamic adjustment mechanism can effectively prevent the welding wire from accumulating in the middle of the spool, ensure uniform distribution between winding layers, and significantly improve the welding wire winding quality.

[0015] 2. The design utilizes a threaded connection between the pressure plate and the retaining plate, allowing for quick fixing or disassembly of the material tray by tightening the pressure plate. It also accommodates the clamping needs of material trays of different sizes. Compared to traditional bolt fixing methods, this improves operational efficiency and requires no additional tools.

[0016] 3. The support plate and rotating seat are locked and unlocked with a spring and slide rod positioning assembly. After winding, pressing the slide rod releases the support plate, which can then be rotated and stored in a horizontal position. This reduces the overall size of the device, making it easier to transport and store, and is especially suitable for field operations.

[0017] 4. The control box integrates a pulse generator and dual drivers, precisely matching the speed ratio of the first and second motors through programming to ensure strict synchronization between wire feeding and lateral oscillation. The combination of slide rails and sliders further suppresses vibration deviation during guide movement, resulting in minimal positioning accuracy error.

[0018] 5. Both the winding and guiding components are driven by independent motors, and the control signals are centrally processed. By modifying the parameter configuration of the pulse generator, it can be adapted to different wire diameters, winding speeds, and reciprocating stroke requirements, enabling rapid switching between multiple process modes without the need for mechanical structure adjustments.
