Description

Technical Field

[0001] This invention relates to the field of welding wire preparation technology, and in particular to a welding wire preparation apparatus and method for multilayer plates with selectable core materials. This equipment can produce wound products that are convenient for production, use and transportation. Background Technology

[0002] Currently, there is a significant gap in the equipment and processes for preparing coiled welding wire for sheet metal. Existing welding wire preparation technologies primarily focus on processing single materials and cannot achieve the preparation of coiled welding wire for sheet metal. This is especially true for the preparation of welding wire for multi-layer sheet metal, where effective technical means and equipment support are lacking. This limitation not only restricts product diversity but also increases the complexity of the preparation process and production costs. Furthermore, the inability to automate operations necessitates greater manual intervention and monitoring, resulting in a failure to effectively improve work efficiency.

[0003] Therefore, there is an urgent need for a novel apparatus and method for preparing selective welding wire for multilayer plates, which can fill the current technological gap, improve preparation efficiency, and optimize product performance. This invention was born out of this context, aiming to solve the problems in the existing technology and provide a practical and efficient solution. Summary of the Invention

[0004] The present invention aims to solve the problems existing in the prior art by providing a welding wire preparation device and method for selecting core materials for multilayer plates. This device and method can complete the plate winding and automatically guide the selected core material into the center of the wound plate, thereby significantly improving work efficiency.

[0005] The technical solution adopted by this invention to solve its technical problem is as follows: a welding wire preparation device for multilayer board with optional core material, including a base, a three-roller winding mechanism above the base, the three-roller winding mechanism being used to wind the board fed into the equipment into an annular roll, the three-roller winding mechanism including two limiting plates fixedly mounted on the base and three winding shafts rotatably mounted between the two limiting plates, the three winding shafts including two fixed winding shafts at the bottom and one movable winding shaft at the top, a height adjustment device being provided between the movable winding shaft and the limiting plates; the height adjustment device can allow it to move up and down a certain distance within a certain range to support different thicknesses or support several boards to be put into the equipment for winding at the same time;

[0006] The three-roller plate winding mechanism is provided with a welding wire feeding device on one side above. The welding wire feeding device can select whether to add core material to the center of the annular coil as needed. The welding wire feeding device includes a threaded pipe for conveying the welding wire through. The threaded pipe is provided with internal threads. Rotating the threaded pipe can cause the internal core material to move outward for addition.

[0007] The welding wire feeding device is equipped with a limiting device, which is used to limit the size in the Z-axis direction during the plate processing and guide the plate to be wound in a predetermined direction so that the annular coil reaches the set thickness and diameter; the limiting device includes two limiting baffles on the left and right sides. When the three-roll plate winding mechanism moves to the limiting baffle, the plate can be wound into an annular coil of the corresponding diameter.

[0008] In a further improvement, the base is equipped with a main motor, and a large gear transmission mechanism is connected between the main motor and two fixed winding shafts. The large gear transmission mechanism includes a driving gear, a first driven gear, and a second driven gear. The driving gear is fixedly installed on the output shaft of the main motor, and the first driven gear and the second driven gear are respectively fixedly connected to the two fixed winding shafts. Both the first driven gear and the second driven gear are meshed with the driving gear.

[0009] To further improve the design, a circular fixing plate is provided behind the limiting baffle. The circular fixing plate is connected to a rotary drive device. The threaded pipe is fixedly connected to the circular fixing plate. The center of the circular fixing plate is provided with a wiring hole that communicates with the threaded pipe.

[0010] In a further improvement, the rotary drive device includes a small motor and a pinion transmission mechanism. The small motor is connected to the threaded pipe through the pinion transmission mechanism. The pinion transmission mechanism includes a pair of driving pinions, which are respectively fixedly connected to the threaded pipes on both sides.

[0011] To further improve the design, a width adjustment mechanism is provided between the limiting baffle and the circular fixed plate. The width adjustment mechanism includes a rotatable adjusting screw. The limiting baffle and the circular fixed plate are slidably connected, and the adjusting screw is threadedly connected to the limiting baffle.

[0012] In a further improvement, the height adjustment device includes a limiting rod and a bearing seat. A rolling bearing is fixedly installed on the bearing seat, and a movable winding shaft is fixedly installed on the rolling bearing. A limiting groove is provided on the limiting fixing plate, and the limiting groove is slidably connected to the bearing seat. The limiting rod is threadedly connected to the limiting fixing plate, and the lower end of the limiting rod is rotatably connected to the bearing seat.

[0013] The beneficial effects of this invention are as follows: In operation, the multi-layer board selective core material preparation device and method designed in this invention involves the board moving upwards and being wound via a winding shaft mechanism. During the winding process, a limiting device guides the board to be wound in a predetermined direction. When the set thickness and diameter are reached, the equipment automatically stops processing. A unique feature of this equipment is its ability to selectively add core material; that is, during the board winding process, core material can be added to the board according to actual processing needs. This device can wind boards with high hardness, and the winding is all completed automatically, with costs far lower than manual winding. Simultaneously, safety is greatly improved, and the number of steps is reduced. Attached Figure Description

[0020] The technical solutions of the embodiments of the present invention will now be fully and thoroughly described with reference to the accompanying drawings. Obviously, the described embodiments constitute only a portion of the embodiments of the present invention, and not all of them. Those skilled in the art can organize and design the components described and shown in the accompanying drawings of the embodiments of the present invention in various different configurations and design schemes based on these embodiments.

[0021] Therefore, the following detailed description of the embodiments of the invention shown in the accompanying drawings is not intended to limit the scope of protection of the invention, but merely illustrates selected embodiments of the invention. All other embodiments that can be obtained by those skilled in the art without innovative effort based on the embodiments of the invention should be considered within the scope of protection of the invention.

[0022] See attached document Figure 1-4 This embodiment describes a welding wire preparation device for multilayer sheet metal with optional core material, mainly comprising a device body and an operating procedure. The device body is based on a common winding mechanism design; the detailed structure and working principle of this mechanism will not be described in detail here. The device body includes a base 1, above which is a three-roller winding mechanism. The three-roller winding mechanism is used to wind the sheet metal fed into the equipment into a ring-shaped coil. The three-roller winding mechanism includes two limiting plates 2 fixedly mounted on the base 1 and three winding shafts rotatably mounted between the two limiting plates 2. The limiting plates 2 provide support for the transverse components of the equipment and restrict their position. The three winding shafts include two fixed winding shafts 5 at the bottom and one movable winding shaft 4 at the top. A height adjustment device is provided between the movable winding shaft 4 and the limiting plates 2; the height adjustment device allows it to move up and down a certain distance within a certain range to support different thicknesses or to support several sheets of different thicknesses being simultaneously fed into the equipment for winding.

[0023] The three-roller plate winding mechanism is provided with a welding wire feeding device on one side above. The welding wire feeding device can select whether to add core material to the center of the annular coil as needed. The welding wire feeding device includes a threaded pipe 12 for conveying the welding wire through. The threaded pipe 12 is provided with internal threads. Rotating the threaded pipe 12 can cause the internal core material to move outward for addition.

[0024] The wire feeding device is equipped with a limiting device, which is used to limit the size in the Z-axis direction during the plate processing and guide the plate to be wound in a predetermined direction so that the annular roll reaches the set thickness and diameter. The limiting device includes two limiting baffles 13 on the left and right sides. When the three-roll plate winding mechanism moves to the limiting baffle 13 while winding the plate, the plate can be wound into an annular roll of the corresponding diameter.

[0025] The base 1 is equipped with a main motor 3, which provides the necessary power source for the entire device. This ensures that the winding shaft can operate normally after the main motor 3 is powered on. A pair of driven gears 7 and 8 are located on the right side of the motor 3. These gears connect to subsequent components, transmitting the power generated by the main motor 3 to these components. A large gear transmission mechanism connects the main motor 3 to the two fixed winding shafts 5. The large gear transmission mechanism includes a driving gear, a first driven gear 7, and a second driven gear 8. The driving gear is fixedly mounted on the output shaft of the main motor 3. The first driven gear 7 and the second driven gear 8 are respectively fixedly connected to the two fixed winding shafts 5, and both the first driven gear 7 and the second driven gear 8 are meshed with the driving gear.

[0026] When using the sheet metal winding device designed in this invention, the main motor 3 is first turned on, and then the sheet metal is placed above the fixed winding shaft 5. The position of the movable winding shaft 4 is adjusted so that the distance between the fixed winding shaft 5 and the movable winding shaft 4 is greater than the thickness of the sheet metal. Subsequently, the sheet metal will gradually bend in the direction of movement of the three winding shafts.

[0027] The limiting baffle 13 is also used to limit the bending direction of the sheet. When the sheet is placed into the fixed winding shaft 5, the sheet will move upward continuously along the movement direction of the fixed winding shaft 5. When the movement contacts the movable winding shaft 4, the sheet will move along the movement direction of the movable winding shaft 5. When the sheet continues to move and contacts the limiting baffle 13, due to the restriction of the limiting baffle 13, the sheet will continue to be wound into a hollow roll with a smaller diameter inside the limiting baffle 13.

[0028] This device can complete the winding of sheet metal in one operation, greatly improving production efficiency. Furthermore, it can add a welding core or other materials inside the sheet metal after winding, a feature many similar devices cannot provide. This device is more cost-effective than other similar devices, giving it a significant competitive advantage. The operation process of this invention is also quite simple, greatly reducing redundant steps, saving operation time, and also reducing the workload of operators, thus improving work efficiency.

[0029] A circular fixing plate 6 is provided behind the limiting baffle 13. The circular fixing plate 6 is connected to a rotary drive device, which can drive the circular fixing plate 6 to perform winding operations. When the sheet material moves between the two circular fixing plates 6, the sheet material will be re-wound into a smaller diameter ring by the action of the two limiting baffles 13. The threaded pipe 12 is fixedly connected to the circular fixing plate 6, and the center of the circular fixing plate 6 is provided with a wiring hole that communicates with the threaded pipe 12.

[0030] The rotary drive device includes a small motor 18 and a pinion transmission mechanism 15. The small motor 18 is connected to the threaded pipe 12 through the pinion transmission mechanism 15. The pinion transmission mechanism 15 includes a pair of driving pinions 19, which are respectively fixedly connected to the threaded pipes 12 on both sides.

[0031] The L-shaped tray 20 is used to place and support various mating parts. A fixing block 17 is located above the L-shaped tray 20, which is used to fix the support rod 16. The fixing block 17 and the support rod 16 are connected and fitted together. A rotary drive device is mounted on the support rod 16. The rotation of a small gear in the rotary drive device drives the threaded pipe 12 to move back and forth. The threaded pipe 12 is a hollow structure, meaning its interior is hollow, and is used to hold the welding core. The purpose of the movement of the threaded pipe 12 is to allow the threaded pipe 12 to drive the welding core to move within a certain distance.

[0032] A width adjustment mechanism is provided between the limiting baffle 13 and the circular fixed plate 6. The width adjustment mechanism includes a rotatable adjusting screw. The limiting baffle 13 and the circular fixed plate 6 are slidably connected, and the adjusting screw is threadedly connected to the limiting baffle 13. This width adjustment device for the limiting baffle can adjust the width according to actual needs. The adjusting screw can adjust the width of the limiting baffle according to actual working conditions.

[0033] The height adjustment device includes a limiting rod 11 and a bearing seat. A rolling bearing 9 is fixedly installed on the bearing seat, supporting and allowing the rotation of the shaft. A movable winding shaft 4 is fixedly installed on the rolling bearing 9. The limiting fixing plate 2 is provided with a limiting slide groove 10, which is slidably connected to the bearing seat. The limiting rod 11 is threadedly connected to the limiting fixing plate 2, and the lower end of the limiting rod 11 is rotatably connected to the bearing seat. The movable winding shaft 4 is installed in the limiting slide groove 10, allowing it to move up and down a certain distance within the limiting slide groove 10 according to actual processing conditions to meet actual processing requirements. The movable winding shaft 4 can move up and down within the limiting slide groove 10 by rotating the limiting rod 11 clockwise or counterclockwise.

[0034] The base 1 is equipped with a coating device for applying a coating to the plate. The coating device includes a coating box 22, and a lifting platform mechanism 23 is provided between the coating box 22 and the base 1. The coating box 22 contains a coating agent that contacts and fixes the winding shaft 5. After the coating agent adheres to the fixed winding shaft 5, it can be rolled onto the surface of the plate to form a coating. The coating agent can be flux, water glass adhesive, or welding rod powder. The lifting platform mechanism 23 is used to adjust the height of the coating box 22, which facilitates the replacement of the coating agent. The lifting platform mechanism 23 adopts a scissor jack structure. Scraper assemblies 24 are provided on the left and right sides of the coating box 22. The scraper assembly 24 consists of an adjusting screw, a scraper plate, and a spring. The adjusting screw is threaded to the coating box. The scraper plate has a through hole that mates with the adjusting screw. The spring is located between the scraper plate and the coating box. By rotating the adjusting screw, the scraper plate can be moved left and right, which can adjust the gap between the scraper plate and the shaft and control the coating thickness.

[0035] The paint box 22 is provided with an extrusion channel 25 in the middle, which is located between two fixed winding shafts 5. The bottom of the extrusion channel 25 is provided with an inlet channel 26, and the two ends of the inlet channel 26 are connected to the paint box 22 with feed ports 27. The feed ports 27 are provided with a screw feeder 28.

[0036] In a preferred embodiment, one of the two limiting and fixing plates 2 may also be provided with a lead screw slide module on its upper part. The lead screw slide module is used to adjust the width between the upper parts of the two limiting and fixing plates 2 to adapt to the width of the plate and facilitate the rolling of narrow plates.

[0038] Step 1: Based on the thickness of the material to be processed, raise the movable winding shaft 4 located at the top of the equipment base 1 to a suitable height in advance;

[0039] Step 2: Adjust the limit baffle 13 to a suitable position according to the actual processing situation and the predetermined dimensions;

[0040] Step 3: Place several sheets of board in the equipment, specifically above the two fixed winding shafts 5 and below the single movable winding shaft 4.

[0041] Step 4: Install the welding wire in the threaded pipe 12 at the top of the equipment. Rotating the threaded pipe 12 will rotate the welding wire out and adjust it to the appropriate position.

[0042] Step 5: Turn on the main switch of the equipment. As the three winding shafts rotate, the board will gradually rotate upwards.

[0043] Step 6: When the sheet material moves to the upper limit baffle 13, the sheet material will be wound in the predetermined direction;
