Description

Technical Field

[0001] This utility model relates to the technical field of strip steel coiling devices, specifically, to a strip steel coiling mechanism for a hot-dip galvanizing production line. Background Technology

[0002] Steel strip is a narrow and long steel plate produced by various steel rolling mills to meet the needs of industrialized production of various metal or mechanical products in different industrial sectors. Hot-dip galvanizing is a process required during the production of steel strip. The main purpose of hot-dip galvanizing is to prevent corrosion and extend its service life. Hot-dip galvanizing is a process in which steel strip is immersed in molten zinc. Through the reaction between iron and zinc, a dense zinc-iron alloy layer is formed on the surface of the steel strip, providing strong corrosion protection. Simultaneously, due to the good ductility and adhesion of zinc, the coating is less prone to damage during various forming processes after hot-dip galvanizing, and it exhibits strong wear resistance during use. Through hot-dip galvanizing, the service life of steel strip is significantly extended, especially in harsh environments.

[0003] Existing strip coiling devices are inconvenient for disassembling the wound strip coils. Furthermore, during the coiling process, the strip is prone to springing back due to stress, increasing the gap in the coil and hindering further coiling. The springing strip can also easily separate from the coiling rod, posing a significant safety hazard during coiling. To address these issues, a strip coiling mechanism for hot-dip galvanizing production lines is proposed. This mechanism utilizes a coiling rod detachable from two sets of connecting plates and a pressure roller whose position is movable during coiling to compress the strip from the side of the coil, thus resolving the aforementioned problems. Utility Model Content

[0004] This utility model proposes a strip steel coiling mechanism for a hot-dip galvanizing production line, which solves the problems in related technologies such as the difficulty in disassembling and removing the coiled strip steel and the springing of the coiled strip steel due to the stress of the strip steel itself during the coiling process.

[0005] The technical solution of this utility model is as follows:

[0006] A strip steel coiling mechanism for a hot-dip galvanizing production line includes a coiling table. A symmetrical groove is formed at the top of the coiling table, and a positioning plate is slidably connected to the top of the groove. A coiling assembly is provided inside the positioning plate. The coiling assembly includes a connecting plate fixedly connected to the inner wall of the positioning plate. A rotating plate is rotatably connected inside the connecting plate. A coiling rod is provided between the two rotating plates. Sliding rods are symmetrically slidably connected to both ends of the coiling rod. A stop is fixedly connected to the outer end of the sliding rod, and the stop engages with the rotating plate. A connecting plate is symmetrically fixedly connected to the inner wall of the connecting plate.

[0007] Optionally, the outer end of the rotating plate is provided with a protrusion, and the outer end of the abutment is provided with a groove. Both the protrusion and the groove are in the shape of a cross. The winding assembly also includes a servo motor fixedly connected to the outer end of one of the connecting plates, and the output end of the servo motor is fixedly connected to the rotating plate.

[0008] Optionally, the winding assembly further includes a support rod fixedly connected inside the connecting plate, the connecting block and the support rod being slidably connected, and a spring being sleeved on the outer end of the support rod, the spring being fixedly connected between the connecting block and the connecting plate.

[0009] Optionally, a slider is slidably connected inside the chute, and the slider is fixedly connected to the positioning plate. A bidirectional lead screw is rotatably connected inside the winding table, and the bidirectional lead screw is threadedly connected to the slider.

[0015] In this invention, the rotating plate and the outer end of the abutment are arranged in a star-shaped pattern with protrusions and grooves to engage the coiling rod between two sets of positioning plates. At the same time, the sliding rod can slide inside the coiling rod, which makes it easy to remove the strip steel coil formed by winding the outer end of the coiling rod. During the coiling process, the extrusion roller squeezes the strip steel coil from the outer end to prevent the strip steel coil from springing open due to stress, thus preventing danger during the coiling process.

[0027] Example 1

[0028] Reference Figures 1-4 This is the first embodiment of the present invention, which proposes a strip steel winding mechanism for a hot-dip galvanizing production line. The mechanism includes a winding table 1, with symmetrically symmetrically arranged grooves 2 at the top of the winding table 1. A positioning plate 3 is slidably connected to the top of the grooves 2. A winding assembly 4 is provided inside the positioning plate 3. The winding assembly 4 includes a connecting plate 401 fixedly connected to the inner wall of the positioning plate 3. A rotating plate 402 is rotatably connected inside the connecting plate 401. A winding rod 403 is provided between the two rotating plates 402. Sliding rods 404 are symmetrically slidably connected to both ends of the winding rod 403. A stop 405 is fixedly connected to the outer end of the sliding rod 404 and engages with the rotating plate 402. A connecting plate 406 is symmetrically fixedly connected to the inner wall of the connecting plate 401. A connecting block 407 is slidably connected inside the connecting plate 406, and a pressing roller 408 is rotatably connected to the outer end of the connecting block 407. The purpose of this setup is that, when coiling the strip steel, firstly, the distance between the two positioning plates 3 is adjusted at the top of the coiling table 1, and then the two abutments 405 are respectively engaged between the rotating plates 402 inside the connecting plate 401. The outer end of the coiling rod 403 is provided with a slot, and one end of the strip steel is engaged with the inside of the slot. When the coiling rod 403 rotates, the strip steel is coiled into shape. As the radius of the strip steel coil increases, the connecting block 407 slides inside the connecting plate 406. The extrusion roller 408 at the outer end of the connecting block 407 extrudes the strip steel coil from the outer end, preventing the strip steel coil from being stressed and springing open during the coiling process, thus preventing danger during the strip steel coiling process.

[0029] Optionally, the outer end of the rotating plate 402 is provided with a protrusion, and the outer end of the abutment 405 is provided with a groove. Both the protrusion and the groove are in a star shape. The winding assembly 4 also includes a servo motor 409 fixedly connected to the outer end of one of the connecting plates 401. The output end of the servo motor 409 is fixedly connected to the rotating plate 402. The purpose of this arrangement is that the star-shaped protrusion and groove enhance the stability of the engagement between the abutment 405 and the rotating plate 402. The servo motor 409 is used to drive the winding rod 403 between the two rotating plates 402 to rotate, thereby winding the strip steel.

[0030] Optionally, the winding assembly 4 further includes a support rod 4010 fixedly connected inside the connecting plate 406. The connecting block 407 is slidably connected to the support rod 4010, and a spring 4011 is sleeved on the outer end of the support rod 4010. The spring 4011 is fixedly connected between the connecting block 407 and the connecting plate 406. The purpose of this arrangement is that the elastic force generated by the spring 4011 increases the squeezing force of the extrusion roller 408 on the outer side of the driven roll, and the support rod 4010 prevents the connecting block 407 from loosening from the inside of the connecting plate 406.

[0031] Example 2

[0032] Reference Figures 1-5 This is the second embodiment of the present invention, which differs from the first embodiment in that:

[0033] Compared to embodiment 1, the further slid groove 2 has a slider 5 internally connected to it, and the slider 5 is fixedly connected to the positioning plate 3. The winding table 1 has a bidirectional lead screw 6 internally connected to it, and the bidirectional lead screw 6 is threadedly connected to the slider 5. The purpose of this arrangement is that when adjusting the distance between the two sets of positioning plates 3, rotating the bidirectional lead screw 6 causes the two sets of sliders 5 to move the positioning plates 3 in opposite directions at the top of the winding table 1.

[0034] Optionally, a side rod 7 is symmetrically fixedly connected to one side of the winding table 1, a guide rail 8 is symmetrically fixedly connected to the inner wall of the side rod 7, a clamp 9 is slidably connected to the top of the guide rail 8, a chuck 10 is rotatably connected inside the clamp 9, the side rod 7 is provided in two sets, a rotating rod 11 is rotatably connected to the bottom of the clamp 9, a clamping plate 12 is rotatably connected between the two rotating rods 11, an included angle is provided between the two rotating rods 11, a nut is fixedly connected to the outer end of the clamping plate 12, a connecting screw 13 is rotatably connected to the internal thread of the nut, and the connecting screw 13 is rotatably connected to the winding table 1. The purpose of this setup is that the strip steel is prone to shifting during the winding process, which affects the flatness of the side end of the strip steel after winding. During the winding process, the two sides of the strip steel move between the chucks 9 and the rollers 10. At the same time, by rotating the connecting screw 13, the clamping plate 12 moves at the outer end of the connecting screw 13, which causes the rotating rod 11 to drive the clamping plate 9 to move at the top of the guide rail 8, thereby adjusting the distance between the two sets of rollers 10. This is suitable for clamping strip steel of different widths.

[0035] Optionally, a tripod 14 is fixedly connected to the top of the side rod 7, and a straightening roller 15 is rotatably connected between the two tripods 14. There are three straightening rollers 15 arranged in a triangle. The purpose of this arrangement is that the three sets of straightening rollers 15 arranged in a triangle inside the tripod 14 can both convey the strip steel and straighten it.
