Abstract
Description
Technical Field
[0001] This invention relates to the field of welding wire production technology, and more specifically to a welding wire coil unwinding device. Background Technology
[0002] In the production of welding wire, thicker steel wires need to be drawn into thinner wires that meet specifications for further processing. The raw material for welding wire is a coil of steel wire wound into a disc. If the steel wire is directly unwound from the coil and then the movable end of the wire is inserted into the drawing equipment, there is a certain degree of danger during the release of the wire coil. During the drawing process, because the wire coil is coiled, there is significant internal stress in the wire, which can easily cause the wire to veer wildly during release, potentially damaging surrounding equipment or injuring workers, posing a considerable risk. Currently, there is no effective device to restrain the unwound steel wire coil to improve safety. Summary of the Invention
[0003] The purpose of this invention is to solve the above-mentioned problems by designing a wire coil unwinding device, which solves the problem of accidental injury that is easily caused during the conventional wire coil unwinding process.
[0004] The technical solution of the present invention to achieve the above objectives is a welding wire coil unloading device, comprising: A wire feeding frame having a guide channel extending vertically; A lifting frame is provided in the guide channel, which can slide up and down. The lifting frame is provided with a first guide wheel and a tension wheel. The first guide wheel is located below the tension wheel, and the tension wheel can swing up and down. A lifting control mechanism is used to control the vertical movement of the lifting frame relative to the guide channel; At least one feeding unit is located on one side of the wire feeding frame. The feeding unit includes a base, a tilting frame, and a driving mechanism. The lower end of the tilting frame is vertically rotatably connected to the base. The tilting frame includes a positioning rod for positioning the welding wire coil. The driving mechanism is mounted on the base and is used to drive the tilting frame to tilt up and down so as to vertically stack the steel wire coil. After being unwound, the welding wire coil threaded on the positioning rod can be passed into the guide channel from one side or top of the wire feeding frame. Then, after being wound at least one turn between the tension wheel and the first guide wheel, it can be released from the bottom of the wire feeding frame. The tension of the welding wire coil can be adjusted by changing the distance between the tension wheel and the first guide wheel.
[0005] Preferably, the lifting control mechanism includes a motor, a wire feeding reel, and a hanging wheel. The hanging wheel is located at the top of the guide channel and is rotatably connected to the wire feeding frame. The motor is fixedly installed on the top of the lifting frame and is used to drive the wire feeding reel to rotate to feed and unfeed the lifting rope. The movable end of the lifting rope on the wire feeding reel passes through the hanging wheel above and is fixedly connected to the lifting frame.
[0006] Preferably, the oscillating frame includes a chassis, a positioning rod fixed perpendicularly to the chassis, and a lever arm welded and fixed to one side of the bottom of the chassis. The bottom of the chassis is rotatably connected to the base via a rotating shaft, and the driving mechanism is connected to the end of the lever arm away from the chassis.
[0007] Preferably, the base has a receiving groove, the driving mechanism is a hydraulic cylinder, the output end of the hydraulic cylinder is hinged to one end of the lever arm away from the chassis, and the other end is hinged to the inner wall or bottom wall of the receiving groove.
[0008] Preferably, the base is provided with a support block for supporting the chassis.
[0009] Preferably, the lifting frame is hinged with a deflector rod that can deflect up and down, and the tensioning wheel is rotatably connected to the deflector rod via a rotating shaft.
[0010] Preferably, the lifting frame is provided with a tension adjusting cylinder, the output end of which is hinged to a rotating shaft for mounting a tensioning wheel, and the other end is hinged to the lifting frame.
[0011] Preferably, the guide channel extends at an angle, both vertically and horizontally.
[0012] Preferably, a take-up frame is provided on the outer side of the pay-off frame. The take-up frame is located near the top of the pay-off frame and has a take-up channel that runs vertically through the frame. The diameter of the take-up channel gradually decreases from bottom to top.
[0013] Preferably, there are two feeding mechanisms, located on both sides of the wire feeding frame, with the two tilting frames inclined towards each other.
[0014] Its advantages over existing technologies are: In this invention, the swaying frame is driven to deflect downward by a driving mechanism, so that the positioning rod on the swaying frame is laid flat, so that the welding wire coil can be hoisted and passed through the positioning rod. Then the driving mechanism drives the swaying frame to flip upward, thereby standing the positioning rod upright. The welding wire coil placed on the swaying frame is also stacked on the positioning rod, and the positioning rod will position the coil.
[0015] During the unwinding process, the movable end of the coil located on the sway frame passes through the top of the unwinding frame, then downwards through the lifting frame, and then sequentially passes through the first guide wheel and the tensioning wheel, winding at least one turn between the first guide wheel and the tensioning wheel. Finally, it exits from the bottom of the unwinding frame and enters the drawing equipment. When the drawing equipment pulls the coil, the coil located on the sway frame is automatically released. Under the constraint of a positioning rod of a certain length, the coil will not scatter or move around, causing no harm to the surrounding area, and will not injure workers, thus improving the safety of unwinding.
[0016] The lifting frame is moved downward by the lifting control mechanism to reduce its height so that the roll material can be manually passed through the first guide wheel and the tensioning wheel. The tensioning wheel can swing up and down to adjust the tension. Attached Figure Description

[0019] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.
[0020] A preferred embodiment of the present invention provides a wire feeding device that can constrain the wire during the feeding process, preventing it from moving around.
[0021] For details, see Figure 1-2 The wire feeding device mainly includes a wire feeding frame 1, a lifting frame 2, a lifting control mechanism 3, and two feeding units 4. The two feeding units 4 are located on both sides of the wire feeding frame 1, and can feed two sets of steel wire coils at the same time.
[0022] like Figure 2 , Figure 3 As shown, the wire feeding frame 1 is erected and fixed on the ground or platform. Both the wire feeding frame 1 and the lifting frame 2 are frame structures, which are spliced and welded together from plates and corner plates.
[0023] The wire feeding rack 1 has a guide channel, which may be continuous vertically or not. The guide channel extends from the bottom to the top of the wire feeding rack 1. The lifting frame 2 is placed within this guide channel. The lifting frame 2 can slide up and down relative to the guide channel via a slider and a slide rail, or it can slide up and down relative to the guide channel via rollers.
[0024] See Figure 3 , Figure 4 In this embodiment, the lifting control mechanism 3 includes a motor 31, a wire reel 32, a hanging wheel 33, and a hanging rope 34 wound on the wire reel 32. The motor 31 is fixedly installed on a flat plate on the top of the lifting frame 2, and the wire reel 32 is placed on a fixed seat (not shown in the figure) on the top of the lifting frame 2. The wire reel 32 can rotate relative to the fixed seat. The motor 31 is used to rotate the wire reel 32 so as to reel in and out the wire.
[0025] The sheave 33 is located at the top of the guide channel and is rotatably connected to the bottom of the top plate of the wire feeding frame 1. The suspension rope 34, wound on the wire feeding reel 32, passes through the sheave 33 above and is then fixedly connected to the lifting frame 2 downwards. The wire feeding reel 32 is driven to rotate by the motor 31, which controls the winding and unwinding of the suspension rope 34, thereby controlling the up and down movement of the lifting frame 2.
[0026] In this embodiment, the wire feeding frame 1 is inclined, and therefore the guide channel is also inclined. When the lifting frame 2 is hoisted, the inner wall of the guide channel on the wire feeding frame 1 can provide partial support for the lifting frame 2, thereby reducing the burden on the motor 31. If the lifting frame 2 adopts a straight up-and-down lifting method, the motor 31 needs to completely overcome the weight of the lifting frame 2 to control the lifting.
[0027] like Figure 4 , Figure 5 As shown, the shape of the lifting frame 2 is adapted to the shape of the guide channel. The first guide wheel 6 is located at the bottom or middle area of the lifting frame 2 and is rotatably connected to the lifting frame 2 via a rotating shaft.
[0028] The first guide wheel 6 has two grooves. In other embodiments, two first guide wheels 6 may be used, each with one groove.
[0029] Both the tensioning wheel 7 and the first guide wheel 6 are located inside the lifting frame 2. The tensioning wheel 7 is located above the first guide wheel 6 and is rotatably connected to one end of the sway bar 8 via a rotating shaft. The other end of the sway bar 8 is rotatably connected to the lifting frame 2. A tension adjustment cylinder 9 is installed inside the lifting frame 2. This tension adjustment cylinder 9 is vertically positioned with its output end facing upwards. The output end of the tension adjustment cylinder 9 is hinged or rotatably connected to the end of the rotating shaft on which the tensioning wheel 7 is mounted, away from the sway bar 8. The tension is controlled by the tension adjustment cylinder 9 to swing up and down. When the tensioning wheel 7 swings up and down, the sway bar 8 also deflects up and down, thereby adjusting the tension of the steel wire wound on the first guide wheel 6 and the tensioning wheel 7.
[0030] like Figure 7 , Figure 8 As shown, the feeding unit 4 mainly includes a base 41, a tilting frame 42, and a drive mechanism. The base 41 has a groove, and the drive mechanism is located within this groove. A bearing seat is provided on each of the two sides of the upper part of the base 41. The tilting frame 42 is rotatably connected to the bearing seat via a rotating shaft, allowing the tilting frame 42 to flip up and down relative to the base 41.
[0031] See Figure 8 The oscillating frame 42 mainly consists of a base 422, a lever arm 423, and a positioning rod 421. The positioning rod 421 is perpendicular to the base 422 and vertically fixed to it. A rotating sleeve is welded to one side of the bottom of the base 422, through which a rotating shaft passes. The base 422 is rotatably connected to the base 41 via the rotating sleeve and the rotating shaft. One end of the lever arm 423 is welded and fixed to one side of the base 422, and the other end extends outward along the radial direction of the base 422.
[0032] See Figure 7In this embodiment, the driving mechanism uses a hydraulic cylinder 43, which is preferably an oil cylinder with strong power. The output rod of the hydraulic cylinder 43 is hinged to the other end of the lever arm 423 (the end away from the chassis 422). The other end of the hydraulic cylinder 43 is hinged to the inner wall or bottom wall of the groove on the base 41.
[0033] See Figure 9 The output rod of the hydraulic cylinder 43 extends and retracts, driving the tilting frame 42 to rotate up and down relative to the base 41, so that the originally vertical positioning rod 421 rotates downward and remains horizontal. This allows the steel wire coil to be hoisted and threaded onto the positioning rod 421, thus completing the loading process quickly.
[0034] The positioning rod 421 passes through the wire coil, and then the hydraulic cylinder 43 drives the tilting frame 42 to flip upward and return to its original position, so that the wire coil will be stacked on the chassis 422 of the tilting frame 42.
[0035] In other implementation schemes, the drive mechanism may also be a motor 31, a cylinder, etc.
[0036] like Figure 9 As shown, two support blocks 10 are also provided at corresponding positions on the base 41. These two support blocks 10 are welded and fixed to both sides of the groove. When the base 422 of the deflector frame 42 returns to its original position, the support blocks 10 can support the base 422 and prevent the deflector frame 42 from deflecting to the other side.
[0037] In this embodiment, the positioning rod 421 is tilted to one side so that after the steel wire coil on the positioning rod 421 is released, the steel wire can approach and go up along the positioning rod 421, and enter the guide channel from the upper side of the wire feeding frame 1.
[0038] The positioning rods 421 of the two feeding units 4 are inclined towards each other. The wire feeding frame 1 is inclined to the side where the two feeding units 4 are located.
[0039] In this embodiment, the bottom surface of the base 41 is inclined, so the tilting bracket 42 mounted on the base 41 remains tilted. In other embodiments, the bottom surface of the base 41 can be designed as a horizontal plane, and the upper surface of the base 41 can be designed as an inclined plane. Alternatively, both the bottom and upper surfaces of the base 41 can be designed as horizontal planes, and the positioning rod 421 fixed on the chassis 422 can be designed as inclined.
[0040] like Figure 1 , Figure 6 As shown, a gathering frame 5 is provided on the inclined side of the pay-off frame 1. The gathering frame 5 is a frame structure. The gathering frame 5 is made up of multiple rings 51 of different diameters welded together by connecting strips 52. The diameter of the rings 51 in the gathering frame 5 increases from top to bottom, eventually forming a frustum-shaped structure, thus forming a frustum-shaped channel that runs vertically through the inside of the pay-off frame 1.
[0041] The take-up frame 5 is welded obliquely to the pay-off frame 1. The smallest opening end of the take-up frame 5 is close to the guide channel on the inner wall of the pay-off frame 1. After the wire coil on one of the feeding units 4 is released, the movable end of the wire coil enters upward from the largest opening of the take-up frame 5, then passes through the take-up frame 5 and exits from the smallest opening.
[0042] During the pulling process, the positioning rod 421 can restrain the steel wire to prevent it from moving around. The coiling frame 5 will further coil the steel wire so that it will not move when it comes into contact with the second guide wheel 11 at the top of the wire feeding frame 1. At the same time, it makes the bent steel wire straight after it comes out from the smallest opening of the coiling frame 5.
[0043] The second guide wheel 11 may not be provided at the top of the wire feeding frame 1. After the steel wire comes out from the gathering frame 5, the bracket passes down through the clearance hole on the top plate of the lifting frame 2.
[0044] See Figure 10 After the steel wire passes through the second guide wheel 11 located at the top of the wire feeding frame 1, it passes down through the clearance hole on the top plate of the lifting frame 2, then passes down through the first wire groove on the first guide wheel 6, then reverses direction and passes up through the tension wheel 7, then passes down through the second wire groove on the second guide wheel 11 and the second guide wheel 6, then passes down through the third guide wheel 12 located on the lower side of the wire feeding frame 1, passes through one side of the wire feeding frame 1, and enters the drawing equipment.
[0045] Motor 31 controls the lifting frame 2 to move downwards and reduce its height so that the steel wire can be manually looped onto the first guide wheel 6 and the tension wheel 7.
[0046] Once the wire coil on one feeding unit 4 has finished being laid out, the wire coil on another feeding unit 4 can be welded end to end to the wire coil on the feeding unit 4 that has finished being laid out. This allows for continuous laying out without the need to rewrap the wire on the lifting frame 2.
[0047] The above technical solutions only embody the preferred technical solutions of the present invention. Any modifications that may be made by those skilled in the art to certain parts thereof embody the principles of the present invention and fall within the protection scope of the present invention.
