Description

Technical Field

[0001] The invention relates to the technical field of flux-cored welding wire processing, and in particular to a flux-cored welding wire processing device. Background Art

[0002] Flux-cored welding wire is made of low-carbon steel or low-alloy steel with good plasticity. Its manufacturing method is to first roll the steel strip into a U-shaped cross-section, then add the welding powder prepared according to the dosage into the U-shaped steel strip, compact it with a rolling mill, and finally draw it. Flux-cored welding wire can be easily designed into welding materials for various purposes (wear-resistant, high-strength, heat-resistant, corrosion-resistant, low-temperature resistant, etc.) by adjusting the type and proportion of the alloy composition of the welding powder. Because its alloy composition can be flexibly and conveniently adjusted, many varieties of flux-cored welding wire cannot be smelted and rolled with solid welding wire.

[0003] Patent CN118180694A discloses a flux-cored welding wire forming and processing device and its use method, comprising a base plate, the upper surface of which is fixedly mounted a strip guide rail, the ends of which are provided with U-shaped guide grooves, and the discharge end of which is fixedly mounted a tapered drawing tube. This invention uses a drive motor to rotate a fixed sleeve mounted on a transmission shaft, causing multiple rotating rods mounted on the outer surface of the fixed sleeve to rotate evenly and swing, thereby allowing the striking blocks fixed on the ends of the rotating rods to strike the upper and lower sides of a C-shaped plate during rotation. Since the hopper is mounted on the support rods via an elastic support mechanism, the C-shaped plate can drive the hopper to vibrate up and down when struck, thereby facilitating the flux in the hopper to fall into the U-shaped steel strip through the two discharge pipes, thus preventing the flux from agglomerating, making it difficult to discharge the flux, and resulting in uneven flux filling.

[0004] In the flux-cored wire forming processing device in the above patent, during the process of applying flux, the rotating rod is controlled to rotate to knock the C-type plate up and down to drive the hopper to vibrate up and down, so as to realize the discharge of the two discharge pipes. However, when discharging, as the mass of the hopper changes, its vibration amplitude will also change, resulting in uneven discharge; and when the flux placed in the steel belt is driven to the bottom of the two pressing wheels by the movement of the steel belt, although it can be suppressed, the flux will be dispersed to both sides due to the squeezing force of the pressing wheels during pressing. Especially when the unit flux filling mass is large, this effect will be more obvious. The pressed flux will be squeezed by the flux being pressed at the edge, and will crack or disperse to varying degrees, resulting in uneven flux filling and poor flux core forming quality. Summary of the Invention

[0034] To make the objectives, technical solutions and advantages of the embodiments of the present invention more clear, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention.

[0035] Example 1, as Figures 1-9 As shown, a drug feeding device for processing flux-cored welding wire includes a drug feeding seat 1, a U-shaped guide groove 11 is provided on the front side of the drug feeding seat 1, a limit strip 12 is fixedly connected to the right side of the U-shaped guide groove 11, a shaping section 2 is slidably connected in the U-shaped guide groove 11, a shaping section 2 has a shaping drug groove and a drug delivery cavity at the bottom, a displacement sensor 21 is fixedly connected to the upper end of the shaping section 2, a drug supply tube 22 is fixedly plugged into the top rear side of the drug delivery cavity, and a pressure relief cavity is provided on the top front side, a pressure relief block 23 is slidably connected to the bottom of the pressure relief cavity, and a sealing partition 4 is provided on the left and right sides of the shaping drug groove respectively;

[0036] There is a partition in the middle of the drug delivery cavity and is rotatably connected to a spiral conveying rod 3. A driving assembly is provided on the right side of the partition. A spiral spring 34 is provided between the driving assembly and the spiral conveying rod 3. An adjusting assembly for adjusting the up and down movement of the sealing partition 4 and the left and right movement of the forming section 2 is provided on the right side of the driving assembly. A medicine storage tank 6 is fixedly connected to the top of the upper medicine seat 1. The bottom of the medicine storage tank 6 is contracted to form a medicine outlet docking with the medicine supply pipe 22, and a dredging assembly is provided in the medicine storage tank 6.

[0037] A U-shaped chute for the steel strip to pass through is provided on the periphery of the bottom of the shaping section 2, and the shaping chute can be combined with the steel strip to form a columnar chamber.

[0038] When applying medicine, the steel strip is passed through the bottom of the shaping section 2 along the U-shaped guide groove 11 by the external conveying mechanism and outputted outwards, and then the steel strip is pressed into a circle in cooperation with the pressing mechanism set on the left side of the medicine-applying seat 1, and the operation of the driving component is controlled. The driving component drives the dredging component to continuously dredge the solder in the medicine storage tank 6 to avoid the solder from arching and agglomerating, ensuring its smooth output, thereby improving the subsequent pressing and forming speed. The synchronous driving component drives the volute spring 34 to rotate the spiral conveying rod 3. As the spiral conveying rod 3 rotates, the solder in the medicine storage tank 6 is pressed under the influence of gravity and dredging. When the component is toggled, the medicine falls into the medicine delivery cavity through the medicine outlet and the medicine supply tube 22, and is continuously input into the shaped medicine groove as the spiral conveying rod 3 rotates. Subsequently, as the solder is continuously delivered to the shaped medicine groove, it is hindered by the left sealing partition 4 and the solder is continuously accumulated and compacted in the shaped medicine groove. Later, when the medicine delivery cavity is also filled with solder, the spiral conveying rod 3 rotates and the conveying resistance is too large to rotate, and the spiral spring 34 automatically deforms to make the adjustment component operate to control the right sealing partition 4 to move downward, cutting the solder into fixed specifications. It can be combined with the steel strip to form a columnar chamber, so the solder is prefabricated into a cylindrical shape, which is convenient for subsequent wrapping with the steel strip. When the steel strip is rolled into a circular shape to wrap the solder, the solder is not easy to loosen due to the compaction effect. Subsequently, as the driving component continues to operate, the sealing partition 4 on the left automatically moves up to open the left port of the shaping tank. When the synchronous adjustment component is in operation, it squeezes the limit strip 12, thereby driving the shaping section 2 to move to the left as a whole to push this section of solder to the previous section of solder in a regular docking, thereby avoiding unevenness and cracking during solder pressing through closed compaction molding. The loose problem is solved and the quality of the flux core is improved. During this period, the displacement sensor 21 monitors the moving distance of the shaping section 2. When the moving distance just reaches the distance where the current section of solder and the previous section of solder are connected, the external conveying mechanism drives the steel belt to shift and switch to convey a new soldering section, and at the same time moves the pressed solder to the position of the previous section of solder, and then cooperates with the control pressure relief block 23 to automatically move upward, increasing the volume of the conveying chamber, thereby reducing the rotation resistance of the spiral conveying rod 3, and the spiral spring 34 can drive each part to quickly and automatically reset, so that the soldering and molding operation can be carried out again.

[0039] Example 2, as Figure 2-Figure 4 As shown, based on the above embodiment, a drive component structure is provided:

[0040] The drive assembly includes a transmission disc 32 rotatably connected to the right wall of the partition, the transmission disc 32 is fixedly connected to the spiral conveying rod 3, a guide sleeve 33 is rotatably connected to the inner wall of the transmission disc 32, and a spiral spring 34 is fixedly connected between the guide sleeve 33 and the transmission disc 32;

[0041] A bracket is provided at the top of the U-shaped guide groove 11, and a driving shaft 5 is rotatably connected to the bracket. The driving shaft 5 is driven by a motor installed on the right wall of the bracket. The upper end of the shaping section 2 is rotatably connected to a transmission sleeve 26 that is movably clamped on the driving shaft 5, and a transmission belt is movably connected between the transmission sleeve 26 and the guide sleeve 33.

[0042] The drive shaft 5 drives the transmission sleeve 26 to rotate, and the transmission sleeve 26 drives the guide sleeve 33 to rotate through the transmission belt. The guide sleeve 33 drives the transmission plate 32 through the volute spring 34 to rotate the spiral conveying rod 3, thereby conveying the solder. When in use, the elastic force of the volute spring 34 is large enough to prevent the volute spring 34 from deforming prematurely before the solder is compacted, thereby driving the adjustment component to operate;

[0043] Since the transmission sleeve 26 is movably connected to the drive shaft 5, when the shaping section 2 moves to the left to push the compacted solder, the drive shaft 5 still stably drives the guide sleeve 33 to rotate, so that after the shaping medicine groove and the drug delivery cavity are filled with solder and the spiral conveying rod 3 cannot rotate, the spiral spring 34 can automatically deform to allow the adjustment component to control the two sealing partitions 4 to cut and release the solder.

[0044] Example 3, as Figure 2 and Figure 7-Figure 8 As shown, based on the above embodiment, a dredging component structure is provided:

[0045] The dredging assembly includes an elastic gear sleeve 61 that is slidably sleeved on the bottom of the medicine storage tank 6. A T-shaped dredging rod 62 is fixedly connected to the inner wall of the elastic gear sleeve 61. A movable groove that is adapted to the elastic gear sleeve 61 is provided on the outer wall of the bottom of the medicine storage tank 6. The T-shaped dredging rod 62 is slidably inserted into the upper wall of the inner cavity of the medicine storage tank 6. The outer periphery of the T-shaped dredging rod 62 is fixedly connected to a linearly arranged multi-row dredging cross bar 63. The left end of the driving shaft 5 is fixedly sleeved with a missing gear 51 that can engage with the elastic gear sleeve 61.

[0046] While the driving assembly drives the spiral conveying rod 3 to transport the solder, the driving shaft 5 drives the missing gear 51 to move the elastic gear sleeve 61 upward, and the elastic gear sleeve 61 drives the T-shaped dredging rod 62 to move each dredging cross bar 63 upward. When the missing gear 51 disengages from the elastic gear sleeve 61, the elastic gear sleeve 61 drives the T-shaped dredging rod 62 and each dredging cross bar 63 to automatically move down and reset under the action of its own elastic force. As the driving shaft 5 drives the missing gear 51 to continue to rotate, the T-shaped dredging rod 62 drives each dredging cross bar 63 to move back and forth up and down to dredge the solder in the medicine storage tank 6, avoid arching and agglomeration, and ensure smooth solder feeding.

[0047] Example 4, as Figure 2 and Figure 9 As shown, based on the above embodiment, a drug supply tube 22 structure is provided:

[0048] A sealing portion is formed on the top edge of the medicine supply tube 22 to movably abut against the medicine outlet.

[0049] When the solder is compacted in the shaped solder groove and pushed to connect with the front solder, the sealing portion at the top of the supply pipe 22 can seal the outlet at the bottom of the storage tank 6 to temporarily interrupt the supply and avoid leakage.

[0050] Example 5, as Figure 3-Figure 7 As shown, based on the above embodiment, an adjustment component structure is provided:

[0051] The adjustment assembly includes a crank tube 42 rotatably connected to the left and right sides of the upper end of the shaping section 2. An L-shaped slide groove 41 is provided on the sealing partition 4. The crank tube 42 is movably engaged with the L-shaped slide groove 41. A guide groove 1 43 and a guide groove 2 44 are respectively provided in the left and right crank tubes 42. An L-shaped guide rod 45 is movably inserted between the crank tubes 42 on both sides. The L-shaped guide rod 45 is provided with two pin protrusions 1 46 that are movably engaged with the guide groove 1 43 and the guide groove 2 44 respectively. The L-shaped guide rod 45 is fixedly connected to the limit bar 12.

[0052] The inner wall of the guide sleeve 33 is slidably engaged with a core sleeve 47 that is movably sleeved on the spiral conveying rod 3. The core sleeve 47 is fixedly connected to the L-shaped guide rod 45. The inner wall of the core sleeve 47 is provided with a pin protrusion 48, and the outer periphery of the spiral conveying rod 3 is provided with a spiral groove 31 that is movably engaged with the pin protrusion 48.

[0053] Furthermore, the guide groove 1 43 is composed of a combination of straight grooves 1 on both sides and an arc groove 1 in the middle, and the guide groove 2 44 is composed of a combination of an arc groove 2 on the left and a straight groove 2 on the right.

[0054] The L-shaped guide rod 45 drives the pin 46 on the right side to squeeze the arc groove 2 on the left side of the guide groove 2 44, thereby driving the crank tube 42 to deflect backward, squeezing the L-shaped slide 41 so that the sealing partition 4 on the right side moves down, cutting off the compacted solder, and the left side. The left side pin convex 146 moves along the straight groove 1 on the left side of the guide groove 143, and the left crank tube 42 still keeps driving the corresponding sealing partition 4 to be fixed, so as to ensure that the left end of the solder will not release pressure and cause the solder to move and deform when the solder is cut off. When the solder is cut off, the right side pin convex 146 is clamped by the arc groove 2 on the left side of the guide groove 144 to the straight groove 2 on the right side, and the left side pin convex 146 is clamped by the straight groove 1 on the left side of the guide groove 143 to the arc groove 1 in the middle, thereby driving the left crank tube 42 to deflect upward, squeezing the L-shaped slide 41 to drive the left sealing partition 4 to move upward, so as to release the cut solder. As the L-shaped guide rod 45 continues to move right, the left side pin convex 146 is clamped by the arc groove 1 in the middle of the guide groove 143 to the straight groove 1 on the right side, and the right side pin convex 146 continues to move along the straight groove 2 on the right side of the guide groove 144 to clamp and move, and the two sealing partitions 4 maintain a stable left-open and right-closed state;

[0055] When the L-shaped guide rod 45 moves to the right, it is limited by the limiting strip 12. When the L-shaped guide rod 45 moves to the right on the shaping section 2, it relatively pushes the shaping section 2 (the shaping section 2 can be made of a lightweight and hard carbon fiber material to reduce the weight and facilitate movement) to move to the left, thereby using the sealing partition 4 on the right to push the solder to dock with the solder in the front section. This method of applying solder not only avoids uneven solder, but also avoids the occurrence of loose cracking on both sides when the solder is pressed.

[0056] Example 6: Figure 2-Figure 3 As shown, based on the above embodiment:

[0057] The left and right sealing partitions 4 are both slidably plugged into the shaping section 2 and slidably connected to the front wall of the upper medicine seat 1 , and can both seal one side of the corresponding shaped medicine groove.

[0058] Through this design, when the crank tube 42 deflects and drives the sealing partition 4 to move up and down, it is ensured that the sealing partition 4 is under balanced force and moves smoothly; when the left sealing partition 4 seals the left side of the shaping medicine groove, the accumulated solder can be reliably compacted and will not leak; when the right sealing partition 4 seals the right side of the shaping medicine groove, it is ensured that the solder will not leak when being pushed.

[0059] Example 7, as Figure 3 As shown, based on the above embodiment:

[0060] The displacement sensor 21 is movably sleeved on the L-shaped guide rod 45 and is used to monitor the movement distance of the L-shaped guide rod 45 .

[0061] When the L-shaped guide rod 45 moves to the right and pushes the limit bar 12 to make the forming section 2 move to the left and push the solder to connect with the front section of solder, the L-shaped guide rod 45 moves relatively through the displacement sensor 21, thereby monitoring the movement distance of the forming section 2. When the movement distance just reaches the distance where this section of solder connects with the front section of solder, the displacement sensor 21 can feedback control the external conveying mechanism to drive the steel belt to shift and switch to convey a new soldering section, and at the same time move the pressed solder to the position of the front section of solder.

[0062] Example eight, as Figure 9 As shown, based on the above embodiment, a pressure relief block 23 control structure is provided:

[0063] A supporting mesh plate 24 is fixedly connected to the top of the pressure relief chamber. An electric push rod 25 is fixedly connected between the supporting mesh plate 24 and the pressure relief block 23 . The electric push rod 25 is electrically connected to the displacement sensor 21 .

[0064] When the displacement sensor 21 feedback controls the external conveying mechanism to drive the steel belt to shift and switch to convey a new soldering section, and at the same time moves the pressed solder to the position of the front solder section, the electric push rod 25 automatically controls the electric push rod 25 to contract and drive the pressure relief block 23 to move upward according to the feedback signal of the displacement sensor 21, so as to increase the volume of the conveying chamber. Under the action of the elastic force accumulated by the compression of the vortex spring 34, the vortex spring 34 releases the elastic potential energy and at the same time drives the spiral conveying rod 3 to squeeze the accumulated solder into the pressure relief block 23. The vortex spring 34 automatically resets relative to the guide sleeve 33, thereby driving the adjustment component and the forming section 2 to partially reset, so as to perform the solder applying and forming operation again.

Various modifications to these embodiments will be readily apparent to one skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention.
