Description

Technical Field

[0001] The present disclosure relates to the technical field of steel strip winding, and in particular to a guide device of a steel strip coiler and a steel strip coiler. Background Art

[0002] Galvanized steel strip is manufactured from ordinary steel strip through a series of processes, including pickling, galvanizing, and packaging. Due to its excellent corrosion resistance, it is widely used. It is primarily used to manufacture metal products that are cold-processed, rather than galvanized. Examples include lightweight steel keels, fence posts, gutters, rolling doors, and bridge frames. In existing technology, medium-width steel strip is first galvanized in a hot-melt zinc bath, coating all surfaces with zinc. After galvanizing, the strip is then cut into thin strips of the required width for packaging by a slitting machine. The thin strips are then coiled for subsequent use.

[0003] The guide devices of existing steel strapping coilers generally have a low degree of automation, a non-compact structure, and occupy a large amount of space, resulting in poor performance. In the prior art, some guide devices are configured as a swing-arm floating structure to meet the requirements of subsequent non-floating coilers that cannot rewind the steel strap. When a non-floating coiler is used, the use of a swing-arm floating guide device can achieve rewinding of the steel strap, so the swing-arm floating guide device is very popular in use. However, the swing-arm floating guide device is prone to causing wear on the edges of the steel strap during rewinding, affecting the product quality of the steel strap. In addition, the guide arm is mechanical and cannot be operated automatically. Summary of the Invention

DETAILED DESCRIPTION

[0026] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present application is described in detail below with reference to the accompanying drawings. The description in this section is only exemplary and explanatory and should not have any limiting effect on the scope of protection of the present application.

[0027] like Figures 1 to 4 The first embodiment of the present application is shown. Figure 1 The diagram shows a schematic diagram of two groups of guide devices 1000, each group of guide devices 1000 includes: a first base 1100, the first base 1100 is provided with a first linear guide rail 1110, a first horizontal drive mechanism 1120 and a guide mechanism, the guide mechanism is clamped in the first linear guide rail 1110, the first horizontal drive mechanism 1120 drives the guide mechanism to move along the first linear guide rail 1110; the guide mechanism includes a guide wheel assembly 1210, a shearing knife assembly 1220 and a shearing drive assembly 1230, the shearing knife assembly 1220 is arranged on one side of the guide wheel assembly 1210, and the shearing drive assembly 1230 drives the shearing knife assembly 1220 to move toward or away from the guide wheel assembly 1210.

[0028] In this embodiment, the first horizontal drive mechanism 1120 is configured as a hydraulic cylinder drive structure. In other embodiments, the first horizontal drive mechanism 1120 can also be configured as other drive structures capable of driving the guide mechanism to move horizontally. The first horizontal drive mechanism 1120 is used to adjust the horizontal position of the guide mechanism so that the guide mechanism is adjusted to an appropriate position relative to the subsequent coiler.

[0029] In a preferred embodiment, the guide wheel assembly 1210 includes a first guide wheel 1211, a second guide wheel 1212, and a third guide wheel 1213, which are sequentially arranged in the conveying direction of the steel strip 2000. The shear blade assembly 1220 is arranged between the first guide wheel 1211 and the second guide wheel 1212, or between the second guide wheel 1212 and the third guide wheel 1213. In this embodiment, the shear blade assembly 1220 is used to cut the steel strip 2000 conveyed in the guide wheel assembly 1210. When the coiler reaches the winding length or weight of the steel strip 2000, the shear blade assembly 1220 cuts the steel strip 2000 conveyed in the guide device 1000.

[0030] Preferably, the diameter of the first guide wheel 1211 is larger than the diameters of the second guide wheel 1212 and the third guide wheel 1213. The first guide wheel 1211 and the third guide wheel 1213 are grooved wheels, and the second guide wheel 1212 is a flat wheel.

[0031] In this preferred embodiment, the first guide wheel 1211 adopts a groove wheel with a larger diameter so as not to cause the steel belt 2000 to bend and deform when it initially contacts and guides the steel belt 2000, thereby completing the initial guiding of the steel belt 2000; the second guide wheel 1212 adopts a flat wheel to make the steel belt 2000 form an S-shape with a smaller curvature, which can stabilize the transmission of the steel belt 2000; the third guide wheel 1213 is closest to the winder, so it adopts a groove wheel with a smaller diameter to accurately guide the steel belt 2000.

[0032] In a preferred embodiment, the shearing drive assembly 1230 includes a first vertical driving hydraulic cylinder 1231, the piston end of the first vertical driving hydraulic cylinder 1231 is connected to a shearing slider 1232, and the shearing slider 1232 is provided with a curved slide 1233 of a set shape extending along the moving direction of the piston end of the first vertical driving hydraulic cylinder 1231; the shearing knife assembly 1220 includes a cam 1221 and a shearing part, the cam 1221 is clamped in the curved slide 1233, and the first vertical driving hydraulic cylinder 1231 drives the shearing part to move horizontally through the cam 1221 clamped in the curved slide 1233.

[0033] In this preferred embodiment, the first vertical drive hydraulic cylinder 1231 drives the shear slider 1232 to move up and down in the vertical space, thereby causing the cam 1221 in the curved slide 1233 connected to the shear slider 1232 to move to different curved sections in the curved slide 1233, thereby causing the cam 1221 to move horizontally, thereby realizing horizontal movement of the shearing part and completing the shearing and cutting process of the steel strip 2000.

[0034] In a preferred embodiment, the shearing portion includes a movable shearing knife 1222 and a static shearing knife 1223. The movable shearing knife 1222 is fixedly connected to the cam 1221 on the side close to the guide wheel assembly 1210. The static shearing knife 1223 is fixed between the first guide wheel 1211 and the second guide wheel 1212. The movable shearing knife 1222 and the static shearing knife 1223 are arranged opposite to each other. The steel belt 2000 transmitted in the guide wheel assembly 1210 passes through the gap between the movable shearing knife 1222 and the static shearing knife 1223.

[0035] In this preferred embodiment, the shearing portion shears the steel belt 2000 when the steel belt 2000 is transmitted between the first guide wheel 1211 and the second guide wheel 1212. In other embodiments, the shearing portion can also be set at a position corresponding to the second guide wheel 1212 and the third guide wheel 1213. In this embodiment, the shearing static knife 1223 is fixed, and the first vertical driving hydraulic cylinder 1231 drives the shearing slider 1232 to move up and down, thereby driving the shearing movable knife 1222 connected to the cam 1221 to move horizontally. When the steel strip 2000 needs to be sheared, the first vertical driving hydraulic cylinder 1231 drives the shearing slider 1232 to move down and move the shearing movable knife 1222 toward the direction of the shearing static knife 1223, so that the steel strip 2000 transmitted between the shearing movable knife 1222 and the shearing static knife 1223 is squeezed and cut; when the steel strip 2000 is cut, the first vertical driving hydraulic cylinder 1231 drives the shearing slider 1232 to move up and move the shearing movable knife 1222 away from the shearing static knife 1223, so that the steel strip 2000 is normally transmitted on each guide wheel of the guide wheel assembly 1210.

[0036] In a preferred embodiment, the guide mechanism also includes a fixing component, which includes a guide main plate 1310 and a guide sub-plate 1320. The guide main plate 1310 is provided with a first protrusion 1311, and the first protrusion 1311 can be slidably clamped in the first linear guide rail 1110; the guide sub-plate 1320 is arranged opposite to the guide main plate 1310, and is fixedly connected to the guide main plate 1310 through a connecting block 1312; the surface of the guide main plate 1310 close to the guide sub-plate 1320 is provided with a shearing seat 1330, and the shearing slider 1232 can be slidably clamped on the shearing seat 1330; the two sides of the shearing static knife 1223 are respectively fixed on the guide main plate 1310 and the guide sub-plate 1320.

[0037] In this preferred embodiment, the guide mechanism is fixed on the first base 1100 through the guide main board 1310, and a first protrusion 1311 is set on the guide main board 1310 corresponding to the first base 1100. The first protrusion 1311 is engaged with the first linear guide rail 1110 on the first base 1100 to achieve a slidable connection to the first base 1100, and the overall sliding of the guide mechanism is achieved by the sliding of the guide main board 1310 on the first base 1100. In this preferred embodiment, a shear seat 1330 is fixed on the guide main plate 1310 between the guide main plate 1310 and the guide sub-plate 1320, and a T-shaped groove is provided on the shear seat 1330. The shear slider 1232 can be slidably clamped on the shear seat 1330, so that when the first vertical driving hydraulic cylinder 1231 drives the shear slider 1232 to move vertically up and down, the shear slider 1232 moves along the shear seat 1330, that is, the shear seat 1330 guides the shear slider 1232, thereby making the movement process of the shear slider 1232 more stable.

[0038] In a preferred embodiment, the curvature of the curved slide 1233 is set according to a set rule, so that when the shearing movable knife 1222 moves toward the shearing static knife 1223, the moving speed of the shearing movable knife 1222 gradually decreases.

[0039] In this preferred embodiment, the curved slide 1233 is configured such that the horizontal distance between the end of the curved slide 1233 closest to the first vertical drive hydraulic cylinder 1231 and the static shear blade 1223 is shorter than the horizontal distance between the end of the curved slide 1233 further away from the first vertical drive hydraulic cylinder 1231 and the static shear blade 1223. In other words, the curved slide 1233 extends and curves from the bottom end to the top end toward the static shear blade 1223. As the first vertical drive hydraulic cylinder 1231 drives the shear slider 1232 downward, the cam 1221 moves within the curved slide 1233 from the bottom end to the top end, causing the movable shear blade 1222 to gradually approach the static shear blade 1223. In addition, the curvature of the curved slide 1233 is set to gradually decrease from the bottom to the top, that is, in the process of the shearing movable knife 1222 approaching the shearing static knife 1223, the curvature of the bottom end of the curved slide 1233 where the cam 1221 is initially located is larger, and the curvature of the top end of the curved slide 1233 where the cam 1221 is finally located is smaller, thereby achieving the goal of gradually reducing the moving speed of the shearing movable knife 1222 in the process of approaching the shearing static knife 1223. In this preferred embodiment, the purpose of setting the initial moving speed of the shearing movable knife 1222 to be faster is to quickly feed it to a position closer to the shearing static knife 1223, and in the final stage of the movement of the shearing movable knife 1222, the moving speed is smaller and it reaches the shearing position slowly, which serves to increase the shear force during shearing with the shearing static knife 1223.

[0040] In a preferred embodiment, a guide block 1340 is provided between the guide main plate 1310 and the guide sub-plate 1320 corresponding to the shearing movable knife 1222. The guide block 1340 is provided with a guide square groove, and the shearing movable knife 1222 can be slidably engaged in the guide square groove.

[0041] In this preferred embodiment, the shearing movable knife 1222 is clamped in the guide square groove of the guide block 1340, so that the shearing movable knife 1222 moves along the guide square groove during movement, thereby enabling the guide block 1340 to provide horizontal guidance for the shearing movable knife 1222 during movement, ensuring the stability of the horizontal movement of the shearing movable knife 1222 and the precise positioning and shearing with the shearing static knife 1223.

[0042] like Figure 5 and Figure 6 The second embodiment of the present application is shown as a schematic diagram, comprising: at least one set of the guide device 1000, a winding mechanism, and a floating drive mechanism of the first embodiment of the present application; the guide device 1000 is disposed on one side of the winding mechanism and transfers the transported steel strip 2000 to the winding mechanism. In this embodiment, the guide device 1000 guides and transfers the steel strip 2000 to be wound onto the winding mechanism, which then winds and reels the steel strip 2000. The floating drive mechanism is used to horizontally move the winding mechanism back and forth, enabling the winding mechanism to rewind and rewind the steel strip 2000.

[0043] Preferably, the reel includes two sets of guide devices 1000, and the two sets of guide devices 1000 are independently controlled. In this preferred embodiment, the two sets of guide devices 1000 can share a common base, and each guide device 1000 is driven to move by its own first horizontal drive mechanism 1120.

[0044] The floating drive mechanism includes a fixed base 4100, on which a servo motor 4200 is mounted. The movable end of the servo motor 4200 is connected to a ball screw 4400 via a first reducer 4300. A screw nut 4500 is threadedly sleeved on the ball screw 4400.

[0045] The winding mechanism includes a floating base 3100, which is fixedly connected to the screw nut 4500 via a push-pull block 3200. A second linear guide rail 4600 is provided on the fixed base 4100 corresponding to the floating base 3100, and the floating base 3100 is slidably engaged in the second linear guide rail 4600.

[0046] A winding motor 3300 is provided on the floating base 3100 , and a movable end of the winding motor 3300 is connected to a winding portion 3500 via a second reducer 3400 ; each group of the guide devices 1000 is provided corresponding to the winding portion 3500 .

[0047] In this embodiment, a fixed base 4100 is fixed at the work site. The piston end of a servo motor 4200 is connected to a first reducer 4300. In this embodiment, the first reducer 4300 is a reducer dedicated to the servo motor 4200. The output end of the first reducer 4300 is connected to the end of a ball screw 4400. The servo motor 4200 drives the ball screw 4400 to rotate, driving the screw nut 4500, which is threaded onto the ball screw 4400, to move back and forth horizontally. This in turn drives the floating base 3100, which is connected to the screw nut 4500, to move back and forth horizontally. In this embodiment, the structure and function of the winding unit 3500 are well-established in the prior art and will not be further described here.

[0048] In this embodiment, a limiting guide groove is provided in the push-pull block 3200, and the floating base 3100 is slidably connected to the push-pull block 3200 through a connecting part that is clamped in the limiting guide groove, so that during the horizontal movement of the screw nut 4500, the floating base 3100 is driven to move synchronously through the push-pull block 3200. At the same time, the push-pull block 3200 plays the role of horizontal single-degree-of-freedom limiting on the floating base 3100, ensuring the movement accuracy of the floating base 3100, so that the winding mechanism can perform the winding work normally.

[0049] In this embodiment, a winding motor 3300 is mounted on the floating base 3100. The piston end of the winding motor 3300 is connected to the second reducer 3400, which in turn is connected to the winding shaft of the winding unit 3500. Specifically, the winding motor 3300 drives the winding unit 3500 to rotate, thereby enabling the winding unit 3500 to normally wind the steel strip 2000. In this embodiment, when the servo motor 4200 is not operating, the winding mechanism performs normal single-strand winding. When the servo motor 4200 is operating, the floating base 3100 moves horizontally on the fixed base 4100, enabling the winding mechanism to perform a forward-backward, double-wound winding of the steel strip 2000. This increases the winding length of a single reel of steel strip 2000 and improves winding efficiency.

[0050] In this embodiment, the number of guide devices 1000 provided in groups is consistent with the number of reels of steel strip 2000 that are simultaneously wound. That is, when the guide devices 1000 are provided in one group, a single steel strip 2000 is transferred to the winding mechanism at a time, so the winding mechanism winds a single reel of steel strip 2000 at a time. When the guide devices 1000 are provided in two groups, two steel strips 2000 are transferred to the winding mechanism at a time, so the winding mechanism winds two reels of steel strip 2000 at a time. The same applies to other groups. Taking the case of two groups of guide devices 1000 as an example, when the servo motor 4200 is not operating, the winding mechanism simultaneously winds two reels of normal single-wound steel strip 2000. When the servo motor 4200 is operating, the winding mechanism simultaneously winds two reels of double-wound steel strip 2000, thereby increasing both the winding length and the winding efficiency.
