Technical Field

[0001] This invention relates to the field of wire rod rust removal technology, and specifically to a wire rod rust removal mechanism. Background Technology

[0002] Wire rod, also known as coiled steel, typically refers to small-diameter round steel coils; the diameter of wire rod is generally in the range of 5-19mm. Before use, wire rod usually undergoes peeling, rust removal, and grinding. Existing wire rod rust removal mechanisms cannot adapt to wire rods of different diameters, causing inconvenience for rust removal of wire rods of different sizes, and the rust removal effect is also unsatisfactory. To solve the above problems, this invention provides a wire rod rust removal mechanism. Summary of the Invention

[0003] To address the aforementioned technical shortcomings, the present invention aims to provide a wire rod rust removal mechanism. Under the drive of the drive mechanism, the outer tube, inner tube, and grinding belt rotate synchronously, allowing the grinding belt to grind the outer surface of the wire rod. By setting a detachable limiting arc plate to adapt to wire rods of different sizes, effective rust removal can be ensured for wire rods of different sizes. This solves the technical problems mentioned in the background art.

[0004] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: The present invention provides a wire rod rust removal mechanism, comprising: an inner tube, a grinding belt for grinding the wire rod, and a limiting arc plate for attaching the grinding belt to the outer side of the wire rod; a support ring plate is integrally provided on the outer periphery of both ends of the inner tube, the wire rod extends along the axis of the inner tube, the wire rod is straightened by an existing straightening mechanism after entering the inner tube, and at the same time, the wire rod moves forward at a constant speed along the axis of the inner tube under the action of a traction mechanism to facilitate rust removal; two pulleys symmetrical about the axis of the inner tube are rotatably mounted on the outer side of the support ring plate, the axes of the two pulleys are located on the same diameter of the inner tube, the grinding belt is wrapped around the outer side of the pulleys, and the rotation of one pulley can drive the two pulleys and the grinding belt to rotate synchronously; Two limiting arc plates are symmetrically arranged on the outer side of the wire rod, and the axes of the two pulleys are located on the axis of symmetry of the two limiting arc plates to ensure that the grinding belt has the maximum contact area with the outer side of the wire rod. In addition, the diameter of the pulleys is much larger than the diameter of the wire rod to avoid interference between the two sides of the grinding belt. The grinding belt is located between the outer side of the wire rod and the inner side of the limiting arc plates, so that the grinding belt is attached to the outer side of the wire rod. Two supporting ring plates are coaxially fixedly installed on the inner side of both ends of the outer tube. Under the drive of the drive mechanism, the outer tube, the inner tube and the grinding belt rotate synchronously, so that the grinding belt grinds the outer side of the wire rod. By setting detachable limiting arc plates to adapt to wire rods of different sizes, effective rust removal can be ensured for wire rods of different sizes.

[0005] Preferably, slots are provided at both ends of the limiting arc plate, and rollers are rotatably installed between the two side walls of the slots. The grinding belt is wound around the outside of the rollers and extends to the inside of the limiting arc plate. By rotatably installing rollers at both ends of the limiting arc plate, the grinding belt transmission jamming is avoided, the smoothness of the grinding belt is improved, and thus the grinding effect is improved.

[0007] Preferably, a rectangular protrusion is integrally provided at the center of the outer side of the limiting arc plate, and a rectangular limiting bucket is fixedly installed at the output end of the electric telescopic rod. The rectangular protrusion is matched and installed inside the rectangular limiting bucket, and the rectangular protrusion and the rectangular limiting bucket are fastened together by several screws. The limiting arc plate can be set to be detachable to adapt to wire rods of different sizes.

[0008] Preferably, the outer tube is fixedly mounted on the outside of the support ring plate at both ends by screws, and the outer tube is rotatably mounted on the support plate; the driving mechanism includes a first servo motor mounted on the side of the support plate, a first drive gear fixedly mounted on the output end of the first servo motor, a first external gear ring provided on the outside of the outer tube, and the first drive gear meshing with the first external gear ring; the first servo motor realizes synchronous driving of the outer tube, the inner tube and the grinding belt, thereby effectively grinding the grinding strip.

[0009] Preferably, the plane containing the axles of the two pulleys on the outer side of one support ring plate is coplanar with the plane containing the axles of the two pulleys on the outer side of the other support ring plate; the axles of the pulleys on the outer side of the support ring plate are coaxially and fixedly connected to the axles of the pulleys on the outer side of the other support ring plate via a first connecting shaft; a second external gear ring is coaxially provided on the outer side of the first connecting shaft; a second servo motor is fixedly installed on the inner side of one support ring plate; the output end of the second servo motor is fixedly connected to a second drive gear; the second drive gear meshes with the second external gear ring; when the grinding belt rotates around the wire rod to perform grinding, the second servo motor drives the two grinding belts to transmit synchronously, thereby avoiding the grinding belts grinding the wire rod at the same position for a long time, which would result in poor grinding effect; the transmission of the grinding belts improves the grinding effect.

[0010] Preferably, the plane containing the axes of the two pulleys on the outer side of one support ring plate is perpendicular to the plane containing the axes of the two pulleys on the outer side of the other support ring plate; the axle of the pulley on the outer side of one support ring plate is fixedly connected to a second connecting shaft, the second connecting shaft is rotatably mounted on the inner side of the other support ring plate, a third external gear ring is coaxially provided on the outer side of the second connecting shaft, a third servo motor is fixedly mounted on the inner side of one support ring plate, the output end of the third servo motor is fixedly connected to a third drive gear, the third drive gear meshes with the third external gear ring, and the second connecting shaft drives the pulley on the outer side of the other support ring plate to rotate through a transmission mechanism; this achieves the misalignment of the grinding positions of the two grinding belts at the same time, completes the same grinding effect, reduces the number of grinding rotations required, and improves grinding efficiency.

[0011] Preferably, the transmission mechanism includes a transmission belt, a pulley is coaxially provided on the outer side of the second connecting shaft, one end of the shaft of one pulley extends to the inner side of the support ring plate and is coaxially connected to another pulley, the two pulleys are connected by transmission belt, and a tensioning wheel for tensioning both sides of the transmission belt is rotatably installed on the inner side of the support ring plate; the transmission mechanism ensures that the two grinding belts rotate synchronously; at the same time, two tensioning wheels are provided to ensure the stable operation of the transmission mechanism.

[0012] The beneficial effects of this invention are as follows: Driven by a drive mechanism, the outer tube, inner tube, and grinding belt rotate synchronously, allowing the grinding belt to grind the outer surface of the wire rod. By setting a detachable limiting arc plate to adapt to wire rods of different sizes, the invention can ensure effective rust removal for wire rods of different sizes.

[0013] When the grinding belt rotates around the wire rod to perform grinding, the second servo motor drives the two grinding belts to transmit synchronously, thereby avoiding the grinding belts grinding the wire rod at the same position for a long time, which would result in poor grinding effect; the transmission of the grinding belts improves the grinding effect.

[0014] The third servo motor of this invention drives the third drive gear, the third external gear ring, and the transmission mechanism to rotate, thereby achieving the misalignment of the grinding positions of the two grinding belts at the same time, completing the same grinding effect, reducing the number of grinding rotations required, and improving grinding efficiency.

Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention. Example

[0026] like Figures 1 to 3As shown, the present invention provides a wire rod rust removal mechanism, comprising: an inner tube 1, a grinding belt 3 for grinding the wire rod 2, and a limiting arc plate 4 for attaching the grinding belt 3 to the outer side of the wire rod 2. Support ring plates 11 are integrally provided coaxially on the outer periphery of both ends of the inner tube 1. The wire rod 2 extends along the axis of the inner tube 1. Upon entering the inner tube 1, the wire rod 2 is straightened by an existing straightening mechanism. Simultaneously, under the action of a traction mechanism, the wire rod 2 moves forward at a uniform speed along the axis of the inner tube 1 to facilitate rust removal. Two pulleys 31 symmetrically mounted about the axis of the inner tube 1 are rotatably mounted on the outer side of the support ring plate 11. The axes of the two pulleys 31 are located on the same diameter of the inner tube 1. The grinding belt 3 is wound around the outer side of the pulleys 31. The rotation of one pulley 31 can drive the two pulleys 31 and the grinding belt 3 to rotate synchronously.

[0027] Two limiting arc plates 4 are symmetrically arranged on the outer side of the wire rod 2. The axes of the two pulleys 31 are located on the axis of symmetry of the two limiting arc plates 4 to ensure that the grinding belt 3 has the maximum contact area with the outer side of the wire rod 2. In addition, the diameter of the pulleys 31 is much larger than the diameter of the wire rod 2 to avoid interference between the two sides of the grinding belt 3. The grinding belt 3 is located between the outer side of the wire rod 2 and the inner side of the limiting arc plates 4, so that the grinding belt 3 is attached to the outer side of the wire rod 2. Two support ring plates 11 are coaxially fixedly installed on the inner side of both ends of the outer tube 5. Under the drive of the drive mechanism, the outer tube 5, the inner tube 1 and the grinding belt 3 rotate synchronously, so that the grinding belt 3 grinds the outer side of the wire rod 2. In this embodiment, under the drive of the drive mechanism, the outer tube 5, the inner tube 1 and the grinding belt 3 rotate synchronously, so that the grinding belt 3 grinds the outer side of the wire rod 2. By setting the detachable limiting arc plates 4 to adapt to wire rods 2 of different sizes, it is possible to ensure effective rust removal for wire rods 2 of different sizes.

[0028] For further details, please refer to Figure 2 and Figure 3 As shown, slots are opened at both ends of the limiting arc plate 4, and rollers 44 are rotatably installed between the two side walls of the slots. The grinding belt 3 is wound around the outside of the rollers 44 and extends to the inside of the limiting arc plate 4. By rotatably installing rollers 44 at both ends of the limiting arc plate 4, the transmission of the grinding belt 3 is prevented from jamming, the smoothness of the grinding belt 3 is improved, and thus the grinding effect is improved.

[0029] For further details, please refer to Figure 2 As shown, the limiting arc plate 4 is detachably installed at the output end of the electric telescopic rod 41. The end of the electric telescopic rod 41 is fixedly installed on the side of the L-shaped plate 42, and the L-shaped plate 42 is fixedly installed on the outer side of the support ring plate 11, ensuring the stable installation of the electric telescopic rod 41. Furthermore, a rectangular protrusion 43 is integrally provided at the center of the outer side of the limiting arc plate 4. A rectangular limiting bucket 411 is fixedly installed at the output end of the electric telescopic rod 41. The rectangular protrusion 43 is matched and installed inside the rectangular limiting bucket 411. The rectangular protrusion 43 and the rectangular limiting bucket 411 are fastened together by several screws. The detachable limiting arc plate 4 is provided to adapt to wire rods 2 of different sizes.

[0030] Furthermore, as shown in the figure, the outer tube 5 is fixedly installed on the outside of the support ring plate 11 by screws at both ends, and the outer tube 5 is rotatably installed on the support plate 6; the driving mechanism includes a first servo motor 61 installed on the side of the support plate 6, a first drive gear 62 fixedly installed at the output end of the first servo motor 61, a first external gear ring 51 provided on the outside of the outer tube 5, and the first drive gear 62 meshing with the first external gear ring 51; the first servo motor 61 realizes synchronous driving of the outer tube 5, the inner tube 1 and the grinding belt 3, thereby effectively grinding the grinding disc 2. Example

[0031] Please see Figure 4 and Figure 5 As shown, based on Embodiment 1, the plane containing the axis of the two pulleys 31 on the outer side of one support ring plate 11 is coplanar with the plane containing the axis of the two pulleys 31 on the outer side of another support ring plate 11; the axle of the pulley 31 on the outer side of the support ring plate 11 is coaxially fixedly connected to the axle of the pulley 31 on the outer side of the other support ring plate 11 through a first connecting shaft 71; a second external gear ring 72 is coaxially provided on the outer side of the first connecting shaft 71; a second servo motor 73 is fixedly installed on the inner side of one support ring plate 11; the output end of the second servo motor 73 is fixedly connected to a second drive gear 731; the second drive gear 731 meshes with the second external gear ring 72; when the grinding belt 3 rotates around the wire rod 2 to achieve grinding, the second servo motor 73 drives the two grinding belts 3 to transmit synchronously, thereby avoiding the grinding belts 3 from grinding the wire rod 2 at the same position for a long time, resulting in poor grinding effect; the transmission of the grinding belts 3 improves the grinding effect. Example

[0032] Please see Figures 5 to 8 As shown, the plane containing the axes of the two pulleys 31 on the outer side of one support ring plate 11 is perpendicular to the plane containing the axes of the two pulleys 31 on the outer side of the other support ring plate 11. This arrangement ensures that the grinding positions of the two grinding belts 3 are misaligned at the same time, achieving the same grinding effect, reducing the number of grinding rotations required, and improving grinding efficiency. The axle of the pulley 31 on the outer side of one support ring plate 11 is fixedly connected to the second connecting shaft 81. The second connecting shaft 81 is rotatably installed on the inner side of the other support ring plate 11. A third external gear ring 82 is coaxially provided on the outer side of the second connecting shaft 81. A third servo motor 83 is fixedly installed on the inner side of one support ring plate 11. The output end of the third servo motor 83 is fixedly connected to the third drive gear 831. The third drive gear 831 meshes with the third external gear ring 82. The second connecting shaft 81 drives the pulleys 31 on the outer side of the other support ring plate 11 to rotate through the transmission mechanism. In this embodiment, the third servo motor 83 drives the third drive gear 831, the third external gear ring 82 and the transmission mechanism to rotate, thereby achieving the misalignment of the grinding positions of the two grinding belts 3 at the same time, completing the same grinding effect, reducing the number of grinding rotations required, and improving grinding efficiency.

[0033] Furthermore, the transmission mechanism includes a transmission belt 84, a pulley 85 coaxially disposed on the outer side of the second connecting shaft 81, and one end of the shaft of one pulley 31 extending to the inner side of the support ring plate 11 coaxially connected to another pulley 85. The two pulleys 85 are connected by transmission belt 84. Tensioning pulleys 86 on both sides of the transmission belt 84 are rotatably mounted on the inner side of the support ring plate 11. The transmission mechanism ensures that the two grinding belts 3 rotate synchronously. At the same time, two tensioning pulleys 86 are provided to ensure the stable operation of the transmission mechanism.
