Description

Technical Field

[0001] This invention relates to the field of flux-cored welding wire technology, and more specifically, to a flux-cored welding wire filling device. Background Technology

[0002] Flux-cored welding wire is a special type of welding wire used for welding. Its core contains welding flux, which is wrapped around a metal wire. Flux-cored welding wire is used for gas-shielded welding, such as MIG welding and MAG welding. The role of the core flux is to provide shielding gas, alloying elements, flux, etc., to optimize the welding process and improve weld quality. In the manufacturing process, a suitable steel strip raw material is first selected, usually low-carbon steel or stainless steel strip, and fed into a rolling mill. After rolling, the steel strip is processed into a U-shaped cross-section, which is the basic shape of the outer layer of the flux-cored welding wire. The U-shaped steel strip provides internal volume for subsequent filling of flux. Different fluxes are formulated according to welding requirements and the performance requirements of the flux-cored welding wire. The composition of the flux powder usually includes metal powder, flux, alloying elements, gas generator, etc., with the aim of improving the formation of shielding gas, the fluidity of the weld pool, and the quality of the weld.

[0003] When filling the cavity of the U-shaped steel strip with the prepared powder, it is usually done by conveying the powder into the U-shaped steel strip through a conveyor belt. During this process, gaps or uneven parts are easily generated between the powder particles, which will affect the subsequent welding quality. Summary of the Invention

[0004] To overcome the above deficiencies, the present invention provides a flux-cored wire filling device that overcomes or at least partially solves the above technical problems.

[0005] This invention is implemented as follows: This invention provides a flux-cored wire filling device, comprising a base frame and a material tank. A frame is mounted on the surface of the base frame, and the material tank is mounted on the surface of the frame for storing flux powder. A primary filling mechanism is mounted on the surface of the frame, the primary filling mechanism comprising: A drive roller is rotatably mounted in the inner cavity of the frame, and a guide roller and a tension roller are also rotatably mounted in the inner cavity of the frame; A conveyor belt, which is sleeved on the surface of the drive roller, guide roller and tension roller, is used to convey medicine powder; The waste material bin is installed on the surface of the frame and is used to collect waste material. The inner wall of the waste material bin is symmetrically fixed with brackets, and a receiving plate is installed between the two brackets. A vibrating block is fixedly installed at the bottom of the receiving plate.

[0006] In a preferred embodiment, a discharge valve is installed at the bottom of the material tank to control the discharge speed, and guide wheels are symmetrically rotated on the surface of the base frame. A U-shaped steel strip passes between two sets of guide wheels and is in contact with the surface of the receiving plate.

[0007] In a preferred embodiment, a first motor is fixedly installed on the side wall of the frame, and the output end of the first motor is fixedly connected to the transmission roller for driving the conveyor belt to rotate. A slider is slidably installed on the side wall of the waste material box, and a crossbar is fixedly installed on the side wall of the slider. A protrusion is fixedly installed on the surface of the crossbar, and the protrusion is in contact with the surface of the vibrating block.

[0008] In a preferred embodiment, a pull rod is installed at one end of the slider, a push plate is fixedly installed at one end of the pull rod, and a first spring is installed in the inner cavity of the waste material box. One end of the first spring is fixedly connected to the push plate and is used to drive the pull rod to move.

[0009] In a preferred embodiment, a rotating shaft is rotatably mounted inside the waste material bin, and a lever is symmetrically fixedly mounted on the surface of the rotating shaft for driving the push plate to move. A second motor is fixedly mounted on the side wall of the waste material bin, and the output end of the second motor is fixedly connected to the rotating shaft for driving the rotating shaft to rotate.

[0010] In a preferred embodiment, a cleaning roller is fixedly installed at one end of the rotating shaft. The surface of the cleaning roller is covered with bristles, which contact the inner wall of the U-shaped steel strip to clean the inner cavity of the U-shaped steel strip.

[0011] By setting up a primary filling mechanism, the powder in the material tank can be sent to the surface of the conveyor belt through the feeding valve. Then, the first motor drives the transmission roller and the conveyor belt to rotate, conveying the powder into the cavity of the U-shaped steel belt. Subsequently, the second motor drives the rotating shaft to rotate. As the rotating shaft rotates, when the actuating rod contacts the push plate, the first spring is compressed, the pull rod drives the crossbar to move backward, and the protrusion squeezes the vibrating block, thereby vibrating the receiving plate and transmitting the vibration to the surface of the U-shaped steel belt, thereby eliminating gaps or uneven parts between the powder particles and ensuring the quality of subsequent welding.

[0012] In a preferred embodiment, a secondary filling mechanism is installed on the surface of the waste material box for secondary filling of the U-shaped steel strip. The secondary filling mechanism includes a packing cylinder, a discharge hole, and a negative pressure pump. The packing cylinder is fixedly installed on the side wall of the waste material box, and a discharge hole is opened at the bottom of the packing cylinder. The negative pressure pump is installed on the side wall of the waste material box, and a hose is connected between the suction end of the negative pressure pump and the bottom of the waste material box. A hose is also connected between the discharge end of the negative pressure pump and the packing cylinder.

[0013] In a preferred embodiment, a sleeve is rotatably fitted onto the surface of the packing cylinder, and a through hole is formed on the surface of the sleeve. A mounting frame is fixedly installed on the side wall of the waste material box, and a vision camera is fixedly installed at the bottom of the mounting frame for observing the filling status of the Chinese medicine powder in the U-shaped steel strip.

[0014] In a preferred embodiment, a gear is fixedly installed on the side wall of the sleeve, an electric telescopic rod is fixedly installed on the surface of the mounting bracket, and a toothed plate is fixedly installed on the telescopic end of the electric telescopic rod. The toothed plate meshes with the gear to drive the sleeve to rotate.

[0015] By setting up a secondary filling mechanism and using a vision camera, the filling status of the medicine powder in the U-shaped steel strip can be observed. When the amount of medicine powder in the U-shaped steel strip is not up to standard, the electric telescopic rod is extended, driving the toothed plate to move down, thereby driving the gear to rotate the sleeve clockwise by 45 degrees, so that the through hole and the discharge hole are connected, and the medicine powder in the filling cylinder can fall down to refill the U-shaped steel strip and ensure the filling quality.

[0016] In a preferred embodiment, an impact frame is fixedly installed on the side wall of the sleeve, and an impact rod is symmetrically slidably installed in the inner cavity of the impact frame. A contact block is fixedly installed at one end of the impact rod, and a limit block is fixedly installed on the surface of the impact rod. A second spring is sleeved on the surface of the impact rod, with one end of the second spring fixedly connected to the impact frame and the other end of the second spring fixedly connected to the contact block for driving the impact rod to move outward. An extrusion block is fixedly installed on the surface of the guide roller for pushing the contact block to move. A scraper is slidably installed in the inner cavity of the waste material box for scraping off the powder overflowing from the surface of the U-shaped steel strip. A third spring is installed in the inner cavity of the waste material box, with one end of the third spring fixedly connected to the scraper for driving the scraper to press tightly against the surface of the U-shaped steel strip.

[0017] By setting an impact rod, the electric telescopic rod drives the sleeve to rotate 45 degrees clockwise. When the through hole and the discharge hole are connected, the impact frame rotates synchronously, so that the contact block and the extrusion block come into contact. When the guide roller rotates, the extrusion block can drive the contact block to swing the impact rod and impact the sleeve, ensuring that the powder is smoothly discharged from the discharge hole and improving the filling efficiency.

[0018] The present invention provides a flux-cored wire filling device, the beneficial effects of which include: By setting up a primary filling mechanism, the powder in the material tank can be sent to the surface of the conveyor belt through the feeding valve. Then, the first motor drives the transmission roller and the conveyor belt to rotate, conveying the powder into the cavity of the U-shaped steel belt. Subsequently, the second motor drives the rotating shaft to rotate. As the rotating shaft rotates, when the actuating rod contacts the push plate, the first spring is compressed, the pull rod drives the crossbar to move backward, and the protrusion squeezes the vibrating block, thereby vibrating the receiving plate and transmitting the vibration to the surface of the U-shaped steel belt, thereby eliminating gaps or uneven parts between the powder particles and ensuring the quality of subsequent welding.

[0019] 2. By setting up a secondary filling mechanism and using a vision camera, the filling status of the medicine powder in the U-shaped steel strip can be observed. When the amount of medicine powder in the U-shaped steel strip is not up to standard, the electric telescopic rod is extended, driving the toothed plate to move down, thereby driving the gear to rotate the sleeve clockwise by 45 degrees, so that the through hole and the discharge hole are connected, and the medicine powder in the filling cylinder can fall down to refill the U-shaped steel strip and ensure the filling quality.

[0020] 3. By setting an impact rod, the electric telescopic rod drives the sleeve to rotate 45 degrees clockwise. When the through hole and the discharge hole are connected, the impact frame rotates synchronously, so that the contact block and the extrusion block come into contact. When the guide roller rotates, the extrusion block can drive the contact block to swing the impact rod and impact the sleeve, ensuring that the powder is smoothly discharged from the discharge hole and improving the filling efficiency.

Medicine powder in material tank 3 can be sent to the surface of conveyor belt 704 through discharge valve 4. Then, the first motor 705 can drive the drive roller 701 and conveyor belt 704 to rotate to convey medicine powder.

[0037] Reference Figures 1-8 As shown, in a preferred embodiment, a waste material bin 706 is installed on the surface of the frame 2 for collecting waste material. Supports 707 are symmetrically fixed to the inner wall of the waste material bin 706, and a receiving plate 708 is installed between the two supports 707.

A slider 710 is slidably installed on the side wall of the waste material bin 706, and a crossbar 711 is fixedly installed on the side wall of the slider 710. A protrusion 712 is fixedly installed on the surface of the crossbar 711, and the protrusion 712 contacts the surface of the vibrating block 709. When the slider 710 moves the crossbar 711, the protrusion 712 can squeeze the vibrating block 709, thereby vibrating the receiving plate 708 and transmitting the vibration to the surface of the U-shaped steel strip 6, thus eliminating gaps or uneven parts between the powder particles and ensuring the subsequent welding quality.

[0038] Reference Figures 1-8As shown, in a preferred embodiment, a pull rod 713 is installed at one end of the slider 710, and a push plate 714 is fixedly installed at one end of the pull rod 713.

The output end of the second motor 718 is fixedly connected to the rotating shaft 716 and is used to drive the rotating shaft 716 to rotate. As the rotating shaft 716 rotates, when the toggle rod 717 contacts the push plate 714, the first spring 715 is compressed, and the pull rod 713 drives the crossbar 711 to move backward. When the toggle rod 717 disengages from the push plate 714, the first spring 715 returns to its original position, and the pull rod 713 drives the crossbar 711 to move in the opposite direction.

[0039] Reference Figures 1-8 As shown, in a preferred embodiment, a cleaning roller 719 is fixedly installed at one end of the rotating shaft 716. The surface of the cleaning roller 719 is equipped with bristles 720, which contact the inner wall of the U-shaped steel strip 6 to clean the inner cavity of the U-shaped steel strip 6. When the second motor 718 drives the rotating shaft 716 to rotate, it drives the cleaning roller 719 and the bristles 720 to rotate synchronously, thereby cleaning the dust and impurities in the inner cavity of the U-shaped steel strip 6 and ensuring the quality of subsequent welding.

[0040] In a preferred embodiment, during use, the U-shaped steel belt 6 is passed between two sets of guide wheels 5. The powder in the material tank 3 is delivered to the surface of the conveyor belt 704 through the feeding valve 4. Then, the transmission roller 701 and the conveyor belt 704 are driven to rotate by the first motor 705, conveying the powder into the cavity of the U-shaped steel belt 6. Subsequently, the rotating shaft 716 is driven to rotate by the second motor 718. As the rotating shaft 716 rotates, when the actuating rod 717 contacts the push plate 714, the first spring 715 is compressed, and the pull rod 713 drives the crossbar 711 to move backward. When the actuating rod 717 disengages from the push plate 714, the first spring 715 returns to its original position, driving the pull rod 713 to drive the crossbar 711 to move in the opposite direction. The protrusion 712 squeezes the vibrating block 709, thereby vibrating the receiving plate 708 and transmitting the vibration to the surface of the U-shaped steel belt 6, thereby eliminating gaps or uneven parts between the powder particles and ensuring the quality of subsequent welding.

[0041] Reference Figures 1-12As shown, in a preferred embodiment, a secondary filling mechanism 8 is installed on the surface of the waste material bin 706 for secondary filling of the U-shaped steel strip 6. The secondary filling mechanism 8 includes a packing cylinder 801, a discharge hole 802, and a negative pressure pump 803. The packing cylinder 801 is fixedly installed on the side wall of the waste material bin 706, and a discharge hole 802 is opened at the bottom of the packing cylinder 801. The negative pressure pump 803 is installed on the side wall of the waste material bin 706. A hose is connected between the suction end of the negative pressure pump 803 and the bottom of the waste material bin 706, and a hose is also connected between the discharge end of the negative pressure pump 803 and the packing cylinder 801. The waste material can be discharged through the negative pressure pump 803. The powder in the box 706 is fed into the packing cylinder 801. A sleeve 804 is rotatably fitted onto the surface of the packing cylinder 801. A through hole 805 is opened on the surface of the sleeve 804. By rotating the sleeve 804, when the through hole 805 is connected to the discharge hole 802, the powder in the packing cylinder 801 can fall downwards to perform secondary filling of the U-shaped steel strip 6 and ensure the filling quality. A mounting frame 806 is fixedly installed on the side wall of the surplus material box 706. A vision camera 807 is fixedly installed at the bottom of the mounting frame 806 to observe the filling status of the powder in the U-shaped steel strip 6, thereby controlling the connection between the through hole 805 and the discharge hole 802.

[0042] Reference Figures 1-12 As shown, in a preferred embodiment, a gear 808 is fixedly installed on the side wall of the sleeve 804, and an electric telescopic rod 809 is fixedly installed on the surface of the mounting bracket 806. A toothed plate 810 is fixedly installed at the telescopic end of the electric telescopic rod 809. The toothed plate 810 meshes with the gear 808 to drive the sleeve 804 to rotate. The filling status of the medicine powder in the U-shaped steel strip 6 can be observed through the vision camera 807. When the filling amount of medicine powder in the U-shaped steel strip 6 is not up to standard, the electric telescopic rod 809 is extended, driving the toothed plate 810 to move downward, thereby driving the gear 808 to drive the sleeve 804 to rotate 45 degrees clockwise, so that the through hole 805 and the discharge hole 802 are connected, and the medicine powder in the filling cylinder 801 can fall downward to refill the U-shaped steel strip 6 and ensure the filling quality.

[0043] Reference Figures 1-12As shown, in a preferred embodiment, an impact frame 811 is fixedly installed on the side wall of the sleeve 804. An impact rod 812 is symmetrically slidably installed inside the impact frame 811 to impact the sleeve 804, ensuring that the powder is smoothly discharged from the discharge hole 802. A contact block 813 is fixedly installed at one end of the impact rod 812, and a limit block 814 is fixedly installed on the surface of the impact rod 812. A second spring 815 is sleeved on the surface of the impact rod 812. One end of the second spring 815 is fixedly connected to the impact frame 811, and the other end of the second spring 815 is fixedly connected to the contact block 813, for driving the impact rod 812 to move outward. A pressing block 816 is fixedly installed on the surface of the guide roller 702 for pushing the contact block 813 to move. An electric telescopic rod is also included. When the drive sleeve 804 rotates clockwise by 45 degrees, making the through hole 805 connected to the discharge hole 802, it drives the impact frame 811 to rotate synchronously, so that the contact block 813 contacts the extrusion block 816. When the guide roller 702 rotates, the extrusion block 816 drives the contact block 813 to drive the impact rod 812 to swing, impacting the sleeve 804, ensuring that the powder is smoothly discharged from the discharge hole 802 and improving the filling efficiency. The inner cavity of the residual material box 706 is slidably equipped with a scraper 817, which is used to scrape off the powder overflowing from the surface of the U-shaped steel strip 6. The inner cavity of the residual material box 706 is equipped with a third spring 818, one end of which is fixedly connected to the scraper 817, which is used to drive the scraper 817 to stick tightly to the surface of the U-shaped steel strip 6.

[0044] In a preferred embodiment, during use, the filling status of the medicine powder in the U-shaped steel strip 6 can be observed through the vision camera 807. When the filling amount of medicine powder in the U-shaped steel strip 6 is not up to standard, the electric telescopic rod 809 is extended, driving the toothed plate 810 to move downward, thereby driving the gear 808 to rotate the sleeve 804 clockwise by 45 degrees, so that the through hole 805 is connected to the discharge hole 802, and the medicine powder in the filling cylinder 801 can fall downward to refill the U-shaped steel strip 6, ensuring the filling quality.

[0045] In a preferred embodiment, the electric telescopic rod 809 drives the sleeve 804 to rotate 45 degrees clockwise, so that the through hole 805 is connected to the discharge hole 802. This causes the impact frame 811 to rotate synchronously, so that the contact block 813 contacts the extrusion block 816. When the guide roller 702 rotates, the extrusion block 816 can drive the contact block 813 to drive the impact rod 812 to swing and impact the sleeve 804, ensuring that the powder is smoothly discharged from the discharge hole 802 and improving the filling efficiency.

[0046] Specifically, the working principle of this flux-cored welding wire filling device is as follows: In use, the U-shaped steel strip 6 is passed between two sets of guide wheels 5. The flux powder in the material tank 3 is sent to the surface of the conveyor belt 704 through the feeding valve 4. Then, the transmission roller 701 and the conveyor belt 704 are driven to rotate by the first motor 705, which conveys the flux powder into the cavity of the U-shaped steel strip 6. Then, the rotating shaft 716 is driven to rotate by the second motor 718. As the rotating shaft 716 rotates, when the actuating rod 717 contacts the push plate 714, the first spring 715 is compressed, and the pull rod 713 drives the crossbar 711 to move backward. When the actuating rod 717 disengages from the push plate 714, the first spring 715 returns to its original position, and the pull rod 713 drives the crossbar 711 to move in the opposite direction. The protrusion 712 squeezes the vibrating block 709, thereby vibrating the receiving plate 708 and transmitting the vibration to the surface of the U-shaped steel strip 6, thereby eliminating gaps or uneven parts between the flux powder and ensuring the subsequent welding quality.

[0047] The filling of the medicine powder in the U-shaped steel strip 6 can be observed through the vision camera 807. When the filling amount of medicine powder in the U-shaped steel strip 6 is not up to standard, the electric telescopic rod 809 is extended, and the toothed plate 810 is driven to move down, thereby driving the gear 808 to rotate the sleeve 804 clockwise by 45 degrees, so that the through hole 805 and the discharge hole 802 are connected, and the medicine powder in the filling cylinder 801 can fall down to refill the U-shaped steel strip 6 to ensure the filling quality.

[0048] Furthermore, when the electric telescopic rod 809 drives the sleeve 804 to rotate 45 degrees clockwise, so that the through hole 805 is connected to the discharge hole 802, it drives the impact frame 811 to rotate synchronously, so that the contact block 813 contacts the extrusion block 816. When the guide roller 702 rotates, the extrusion block 816 can drive the contact block 813 to drive the impact rod 812 to swing and impact the sleeve 804, ensuring that the powder is smoothly discharged from the discharge hole 802 and improving the filling efficiency.

[0049] The above are merely preferred embodiments of the present invention and are not intended to limit the present invention.
