Abstract
Description
Technical Field
[0001] This utility model relates to the field of uncoiler technology, and in particular to an uncoiler for preventing strip steel from uncoiling. Background Technology
[0002] Section steel is a type of strip steel with a specific cross-sectional shape and size. The production process of section steel includes feeding, leveling, punching, roll forming, straightening, and cutting. Currently, section steel on the market is further processed from steel strip coils. In the production process of section steel, the steel strip needs to be transported to an uncoiler to be uncoiled before it can proceed to subsequent forming processes.
[0003] In traditional strip coil uncoiling operations, strip coils often suddenly unwind during the uncoiling process. This is because there is a lack of effective anti-unwinding measures. The elasticity and internal stress of the strip coil itself make it easy to loosen spontaneously when not being pulled. This can not only cause the strip to entangle and knot, affecting subsequent processing, but also cause scratches and damage to the strip surface, reducing product quality. Utility Model Content
[0004] The purpose of this invention is to provide an uncoiler for preventing strip steel from uncoiling, so as to solve at least one of the problems mentioned in the background art.
[0005] To achieve the above objectives, this utility model provides the following technical solution: an uncoiler for preventing strip steel from uncoiling, comprising a mounting base, and further comprising:
[0006] A limiting mechanism is provided, which is mounted on a mounting base. The limiting mechanism includes a rotating shaft mounted on the mounting base. The limiting mechanism is used to ensure that the strip does not rotate freely with the rotating shaft when the strip is uncoiled, thereby achieving the function of limiting the movement.
[0007] An extrusion mechanism is mounted on a mounting base. The extrusion mechanism includes a rectangular mounting plate mounted on the mounting base. The extrusion mechanism is used to extrude and limit the strip steel when uncoiling it, ensuring that the extruded position of the strip steel is always lower than the horizontal position of the rotating shaft, thereby achieving continuous tension of the strip steel and preventing the strip steel from spreading out.
[0008] Preferably, the limiting mechanism includes a rotating shaft rotatably mounted on the mounting base, the rotating shaft rotatably passing through the mounting base, and a steel coil fixedly sleeved on the rotating shaft.
[0009] Preferably, the limiting mechanism further includes two limiting components, each including a square hollow frame fixedly installed on the right side of the mounting base, with strip grooves respectively formed on the top inner wall and bottom inner wall of the square hollow frame.
[0010] Preferably, the limiting component further includes two rectangular sliding plates slidably installed in two strip grooves, with limiting springs fixedly installed on the opposite sides of the two rectangular sliding plates, and the opposite ends of the two limiting springs fixedly connected to the front inner wall and the back inner wall of the square hollow frame, respectively.
[0011] Preferably, two rotating blocks are fixedly sleeved on the rotating shaft, and rollers are rotatably mounted on the top and bottom ends of the two rotating blocks respectively.
[0012] Preferably, the extrusion mechanism includes a rectangular mounting plate fixedly installed on the top of the mounting base, a hydraulic cylinder fixedly installed at the bottom of the rectangular mounting plate, a chamfered mounting plate fixedly installed at the output end of the hydraulic cylinder, and an extrusion roller rotatably installed inside the chamfered mounting plate.
[0013] Preferably, strip mounting plates are fixedly installed on the left and right inner walls of the mounting base, and a limit roller is rotatably installed on the side of the two strip mounting plates that are close to each other.
[0014] Preferably, the front end of the strip coil passes through the limiting roller and the extrusion roller, and the strip coil is in contact with both the limiting roller and the extrusion roller.
[0015] The beneficial effects of this utility model are as follows:
[0016] In this utility model:
[0017] 1. During use, pulling one end of the strip coil causes it to unwind. Activating the hydraulic cylinder lowers the C-shaped mounting plate, which in turn lowers the extrusion rollers. The extrusion rollers then compress the strip coil, causing it to descend and deform until its bottom side contacts the limit rollers. At this point, because the coil is pulled higher than the extrusion rollers during descent, it is tightened, effectively preventing it from suddenly unwinding when not being pulled. The extrusion rollers and limit rollers also reduce friction with the strip coil during pulling, allowing for smooth unwinding.
[0018] 2. When the strip coil is pulled, it will drive the rotating shaft to rotate. The rotating shaft will drive two rotating blocks to rotate synchronously. The rotating blocks will drive the rollers to rotate. The rollers will simultaneously contact the two rectangular sliding plates inside the square hollow frame. When the rollers contact the rectangular sliding plates, the rectangular sliding plates will move away from the rotating shaft. At this time, the limit spring will be compressed and deformed. The compression force generated by the limit spring will limit the rotation of the rotating shaft, thereby ensuring that the rotating shaft will not rotate freely. This prevents the rotating shaft from rotating freely when the strip coil is pulled, thus preventing the strip coil from loosening due to free rotation. Attached Figure Description

Detailed Implementation
[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0026] This utility model provides, for example Figure 1-5An uncoiler for preventing strip steel from uncoiling is shown, comprising a mounting base 1 and further comprising: a limiting mechanism, which is mounted on the mounting base 1 and includes a rotating shaft 101 mounted on the mounting base 1; the limiting mechanism ensures that the strip steel does not rotate freely with the rotating shaft 101 during uncoiling, thereby achieving a limiting function; and a pressing mechanism, which is mounted on the mounting base 1 and includes a rectangular mounting plate 2 mounted on the mounting base 1; the pressing mechanism presses and limits the strip steel during uncoiling, ensuring that the pressed position of the strip steel is always below the horizontal position of the rotating shaft 101, thereby achieving continuous tension of the strip steel and preventing it from uncoiling. The limiting mechanism includes a rotating shaft 101 rotatably mounted on the mounting base 1, the rotating shaft 101 rotatably passing through the mounting base 1, and a strip steel coil 102 fixedly sleeved on the rotating shaft 101. The limiting mechanism also includes two limiting components. Each limiting component includes a square hollow frame 103 fixedly mounted on the right side of the mounting base 1. Strip grooves 104 are respectively formed on the top and bottom inner walls of the square hollow frame 103. The limiting components also include two rectangular sliding plates 105 slidably mounted within the two strip grooves 104. Limiting springs 106 are fixedly mounted on the opposite sides of the two rectangular sliding plates 105, and the opposite ends of the two limiting springs 106 are fixedly connected to the front and back inner walls of the square hollow frame 103, respectively. Two rotating blocks 107 are fixedly sleeved on the rotating shaft 101, and rollers 108 are rotatably mounted on the top and bottom ends of the two rotating blocks 107, respectively.
[0027] When the strip coil 102 is pulled, it will drive the rotating shaft 101 to rotate. The rotating shaft 101 will drive the two rotating blocks 107 to rotate synchronously. The rotating blocks 107 will drive the roller 108 to rotate. The roller 108 will simultaneously contact the two rectangular slide plates 105 inside the square hollow frame 103. When the roller 108 contacts the rectangular slide plate 105, the rectangular slide plate 105 will move away from the rotating shaft 101. At this time, the limiting spring 106 will be compressed and deformed. The compression force generated by the limiting spring 106 will limit the rotation of the rotating shaft 101, thereby ensuring that the rotating shaft 101 will not rotate freely. This will prevent the rotating shaft 101 from rotating freely when the strip coil 102 is pulled, and prevent the strip coil 102 from becoming loose due to free rotation.
[0028] The extrusion mechanism includes a rectangular mounting plate 2 fixedly mounted on the top of the mounting base 1. A hydraulic cylinder 201 is fixedly mounted on the bottom of the rectangular mounting plate 2. A U-shaped mounting plate 202 is fixedly mounted on the output end of the hydraulic cylinder 201. An extrusion roller 203 is rotatably mounted inside the U-shaped mounting plate 202. Strip-shaped mounting plates 204 are fixedly mounted on the left and right inner walls of the mounting base 1, respectively. A limit roller 205 is rotatably mounted on the side of the two strip-shaped mounting plates 204 that are close to each other. The front end of the strip coil 102 passes through the limit roller 205 and the extrusion roller 203, and the strip coil 102 is in contact with both the limit roller 205 and the extrusion roller 203.
[0029] During use, one end of the strip coil 102 is pulled to unwind it. The hydraulic cylinder 201 is activated, which drives the C-shaped mounting plate 202 to descend. The C-shaped mounting plate 202 then drives the extrusion roller 203 to descend, which in turn extrudes the strip coil 102. The strip coil 102 descends and undergoes a certain deformation until its bottom side contacts the limit roller 205. At this point, because the position of the strip coil 102 during descent is higher than the position of the extrusion roller 203, the strip coil 102 is tightened, effectively preventing it from suddenly unwinding when not being pulled. The extrusion roller 203 and the limit roller 205 can reduce the friction with the strip coil 102 when it is pulled, allowing the strip coil 102 to unwind smoothly.
[0030] The working principle of the uncoiler for preventing strip steel from uncoiling provided by this utility model is as follows:
[0031] During use, one end of the strip coil 102 is pulled to unwind it. The hydraulic cylinder 201 is activated, which drives the C-shaped mounting plate 202 to descend. The C-shaped mounting plate 202 then drives the extrusion roller 203 to descend, which in turn extrudes the strip coil 102. The strip coil 102 descends and undergoes a certain deformation until its bottom side contacts the limit roller 205. At this point, because the position of the strip coil 102 during descent is higher than the position of the extrusion roller 203, the strip coil 102 is tightened, effectively preventing it from suddenly unwinding when not being pulled. The extrusion roller 203 and the limit roller 205 can reduce the friction with the strip coil 102 when it is pulled, allowing the strip coil 102 to unwind smoothly.
[0032] When the strip coil 102 is pulled, it will drive the rotating shaft 101 to rotate. The rotating shaft 101 will drive the two rotating blocks 107 to rotate synchronously. The rotating blocks 107 will drive the roller 108 to rotate. The roller 108 will simultaneously contact the two rectangular slide plates 105 inside the square hollow frame 103. When the roller 108 contacts the rectangular slide plate 105, the rectangular slide plate 105 will move away from the rotating shaft 101. At this time, the limiting spring 106 will be compressed and deformed. The compression force generated by the limiting spring 106 will limit the rotation of the rotating shaft 101, thereby ensuring that the rotating shaft 101 will not rotate freely. This will prevent the rotating shaft 101 from rotating freely when the strip coil 102 is pulled, and prevent the strip coil 102 from becoming loose due to free rotation.
[0033] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
