Description

Technical Field

[0001] This utility model relates to the field of steel packaging technology, and in particular to a manual packing device for horizontally coiled steel strips. Background Technology

[0002] Hot-rolled strip steel is an important industrial raw material, playing a vital role in the national economy. After hot rolling, the strip steel is coiled into coils by a coiler, and then transported by a coil transport trolley to the bundling station. There, it is bundled by a fully automatic bundling machine. After processes such as marking and weighing, it is finally hoisted into storage by an overhead crane. However, in actual production, occasional malfunctions of the fully automatic bundling machine occur, preventing the coils from being automatically bundled. In such cases, manual bundling is required after the coils have been moved to the ground. Manual bundling requires workers to pre-cut the steel strip to an appropriate length, then wrap the strip around the coil circumferentially, and use a steel strip bundling machine to connect both ends of the strip to the locking buckle. Excess strip is then cut off. This process requires workers to move the steel strip bundling machine manually, increasing their labor intensity. Furthermore, because the steel strip is pre-cut based on estimation, excess strip is often cut off after bundling, resulting in waste. Therefore, a device is needed to assist in the manual bundling of steel coils. Utility Model Content

[0003] To address the problems existing in the prior art, this utility model provides a manual packaging device for horizontally coiled steel strips, which reduces the labor intensity of workers and greatly increases the flexibility of packaging.

[0004] To achieve the above objectives, this utility model provides the following technical solution:

[0005] A manual packing device for horizontally coiled steel strip includes a column fixed to the ground, a swing arm axially connected to the column, two movable supports located on the swing arm, a strapping machine and a steel strip coil assembly respectively connected to the movable supports. The swing arm has movable grooves on both sides, and the movable supports have multiple rollers symmetrically arranged at their upper ends, with the rollers located within the movable grooves on both sides of the swing arm. The steel strip coil assembly includes a steel strip support plate, a steel strip fixing cover, and a cap. The steel strip support plate is perpendicular to the ground and has a support rod on one side for placing the steel strip coil. The steel strip fixing cover is movably sleeved on the outside of the support rod. The other end of the support rod has an external thread, and the cap has a mating internal thread, pressing the steel strip fixing cover against the steel strip support plate. The support rod has symmetrical positioning protrusions, and the steel strip fixing cover has positioning grooves that mate with the positioning protrusions.

[0006] The aforementioned manual packaging device for horizontally coiled steel strip includes a limiting shaft, a limiting plate, a limiting seat, a limiting disc, and a fixing plate on the steel strip support plate. The limiting seat and the fixing plate are arranged in parallel and fixedly connected to the side wall of the steel strip support plate. The limiting shaft is close to the side wall of the steel strip support plate and fixedly connected to it. Its other end is provided with a limiting connecting plate. Both ends of the limiting plate are provided with connecting shafts. One end of the connecting shaft passes through the limiting connecting plate and is provided with a handle. The other end passes through the limiting seat and is connected to the limiting disc. The other end of the limiting disc is provided with a rotating shaft, which is movably connected to the fixing plate. A return spring is sleeved on its outer side. The limiting disc is provided with limiting protrusions protruding from all sides. The limiting seat is provided with a limiting slot. The limiting protrusions cooperate with the limiting slots to limit the rotation direction of the limiting plate.

[0007] In the aforementioned manual packaging device for horizontally coiled steel strip, an electric hoist is provided between the movable support and the steel strip coil assembly. The electric hoist is mounted at the lower end of the movable support, and its hook is fixedly connected to the steel strip support plate by a steel wire rope.

[0008] The manual packaging device for the above-mentioned steel strip coil has multiple fixing rods on one side of the steel strip fixing cover, and the other end of the fixing rods abuts against the steel strip support plate.

[0009] The manual packaging device for horizontally coiled steel strips mentioned above also includes a guide shaft on the steel strip support plate.

[0010] The aforementioned manual packing device for horizontally coiled steel strips includes a spring balancer between the movable support and the strapping machine.

[0011] The manual packaging device for the above-mentioned strip coil has a swing arm connecting plate fixedly installed at the upper end of the column. The swing arm connecting plate is axially connected to the swing arm. One side of the swing arm is provided with two baffles, one end of which is connected to the swing arm and the other end extends outward from the swing arm.

[0012] The beneficial effects of adopting the above technical solution are as follows:

[0013] This utility model is installed on one side of the track of the coil transport trolley, with the swing arm and column axially connected. When manual bundling is not required, the swing arm is parallel to the movement direction of the coil transport trolley and will not affect the operation of the trolley. When manual bundling is required, the swing arm can be rotated to make it perpendicular to the movement direction of the coil transport trolley, dragging the strapping machine or steel strip coil assembly, causing the rollers to move along the swing arm, and driving the moving bracket and its components to move to the appropriate position along the swing arm. This eliminates the need to manually move the strapping machine or steel strip coil, reducing the labor intensity of workers and improving work efficiency. This utility model also uses a steel strip support plate, a steel strip fixing cover, and a cap to fix the steel strip roll under the movable support. When in use, the movable end of the steel strip roll is pulled directly to make it wrap around the steel roll in the circumference, and then the steel strip is cut by a strapping machine. There is no need for workers to pre-cut the steel strip according to the diameter of the steel roll, which makes the use of the steel strip more flexible and thus does not generate steel strip waste. In addition, the steel strip support plate is also equipped with a limiting plate. The rotation direction of the limiting plate is limited by the limiting seat and the limiting disc to ensure that the steel strip will not return to the steel strip roll after use.

[0021] like Figure 1 , 2 As shown, this utility model includes a column 1 fixed on the ground, a swing arm 2 located at the upper end of the column 1 and axially connected to the column 1, two movable supports 3 located on the swing arm 2, a strapping machine 4 and a steel strip roll assembly 5 respectively connected to the movable supports 3. The swing arm 2 is provided with movable grooves 21 on both sides. The movable supports 3 are symmetrically provided with multiple rollers 31 at the upper end. The multiple rollers 31 are located in the movable grooves 21 on both sides of the swing arm 2. By fixing the column 1 of this utility model to one side of the track of the coil transport trolley 9, the swing arm 2 is parallel to the moving direction of the coil transport trolley 9. The automatically bundled steel coils 8 can directly pass through the manual packaging station along the track. When there are steel coils 8 that need to be manually bundled, the operator can control the coil transport trolley 9 to stop moving, and then rotate the swing arm 2 so that the swing arm 2 is perpendicular to the moving direction of the coil transport trolley 9, and drag the strapping machine 4 or the steel strip roll assembly 5 to move it along the swing arm 2 to a suitable position, without having to move the strapping machine 4 or the steel strip roll 10 by hand.

[0022] like Figure 2 , 3As shown, the steel strip coil assembly 5 includes a steel strip support plate 51, a steel strip fixing cover 52, and a cap 53. The steel strip support plate 51 is set perpendicular to the ground, and a support rod 54 is provided on one side for placing the steel strip coil 10. The steel strip fixing cover 52 is movably sleeved on the outside of the support rod 54. The other end of the support rod 54 is provided with an external thread, and the cap 53 is provided with an internal thread that mates with it. The cap 53 presses the steel strip fixing cover 52 against the steel strip support plate 51. The support rod 54 is provided with symmetrical positioning protrusions 541, and the steel strip fixing cover 52 is provided with... A positioning groove 521 is provided. By engaging the positioning protrusion 541 in the positioning groove 521, the steel strip fixing cover 52 can be prevented from rotating with the steel strip roll 10. By placing the steel strip roll 10 on the support rod 54 and then using the steel strip fixing cover 52 to limit the steel strip roll 10, when manual bundling is required, the worker can directly pull the movable end of the steel strip roll 10 to make it wrap around the steel roll 8 in the circumference, and then use the bundling machine 4 to cut the steel strip. There is no need for the worker to pre-cut the steel strip according to the diameter of the steel roll 8, which makes the use of the steel strip more flexible and thus does not generate steel strip waste.

[0023] The steel strip fixing cover 52 of this utility model is provided with a plurality of fixing rods 522 on one side. The other end of the fixing rods 522 abuts against the steel strip support plate 51. The steel strip roll 10 is surrounded by the steel strip support plate 51, the steel strip fixing cover 52 and the fixing rods 522, which can prevent the steel strip roll 10 from being too loose.

[0024] like Figure 3-5As shown, the steel strip support plate 51 is provided with a limiting shaft 55, a limiting plate 56, a limiting seat 57, a limiting disc 58, and a fixing plate 59. The limiting seat 57 and the fixing plate 59 are arranged in parallel and are fixedly connected to the side wall of the steel strip support plate 51. The limiting shaft 55 is close to the side wall of the steel strip support plate 51 and is fixedly connected to the steel strip support plate 51. A limiting connecting plate 551 is provided at the end away from the steel strip support plate 51. Both ends of the limiting plate 56 are provided with connecting shafts. The connecting shaft at one end of the limiting plate 56 passes through the limiting connecting plate 551 and is provided with a handle 561. The other end passes through the limiting seat 57 and is connected to the limiting disc 58. The other end of the limiting disc 58 is provided with a rotating shaft 581. The rotating shaft 581 is movably connected to the fixing plate 59, and a return spring 582 is sleeved on its outer side. The limiting disc 58 is provided with... The device has protruding limiting protrusions 583 on all sides. The limiting seat 57 is provided with a limiting groove 571. The limiting protrusions 583 cooperate with the limiting groove 571 to limit the rotation direction of the limiting plate 56. When the steel strip needs to be pulled out, the limiting plate 56 is perpendicular to the ground, and the steel strip is located in the gap between the limiting shaft 55 and the limiting plate 56. When the steel strip is finished, you can hold the handle and push the limiting plate 56 towards the limiting seat 57 to make the limiting protrusions 583 leave the limiting groove 571. Then, rotate the handle 561 90° to make the limiting plate 56 parallel to the ground. After releasing the handle, under the action of the return spring 582, the limiting protrusions 583 are engaged in the limiting groove 571. At this time, the limiting plate 56 presses the steel strip against the limiting shaft 55, which can prevent the moving end of the steel strip from falling back onto the steel strip reel and facilitate the next use.

[0025] like Figure 1 As shown, an electric hoist 6 is provided between the movable support 3 and the steel strip coil assembly 5. The electric hoist 6 is mounted on the lower end of the movable support 3, and its hook is fixedly connected to the steel strip support plate 51 by a steel wire rope. The height of the steel strip coil assembly 5 can be adjusted by the electric hoist 6 to facilitate the replacement of the steel strip coil 10.

[0026] The present invention provides a spring balancer 7 between the movable support 3 and the strapping machine 4 for suspending the strapping machine 4. The spring balancer 7 can quickly reset the strapping machine 4, reducing the labor intensity of the workers.

[0027] like Figure 2 , 3 As shown, the steel strip support plate 51 is also provided with a guide shaft, which guides the movement path of the movable end of the steel strip coil 10.

[0028] like Figure 1As shown, a swing arm connecting plate 11 is fixedly provided on the upper end of the column 1. The swing arm connecting plate 11 is axially connected to the swing arm 2. Two baffles 22 are provided on one side of the swing arm 2. One end of the baffle is connected to the swing arm 2, and the other end extends outward from the swing arm 2. When the swing arm 2 is perpendicular to the moving direction of the winding trolley 9, the upper end of the baffle 22 contacts the side wall of the swing arm connecting plate 11, so that the swing arm 2 cannot continue to rotate, thus limiting the swing arm 2.

[0029] Work process:

[0030] 1. The coil transport trolley 9 transports steel coils 8 along the track. The axis of the steel coil 8 is perpendicular to its direction of movement. The column 1 of this utility model is fixed on one side of the track of the coil transport trolley 9. The swing arm 2 is parallel to the direction of movement of the coil transport trolley 9. The automatically bundled steel coils 8 can directly pass through the manual packaging station along the track. When there are steel coils 8 that need to be manually bundled, the staff can control the coil transport trolley 9 to stop moving, and then pull the steel strip coil assembly 5 or the strapping machine 4 to make the swing arm rotate until it is perpendicular to the direction of movement of the coil transport trolley 9. The strapping machine 4 or the steel strip coil assembly 5 is dragged, and the roller 31 can move in the moving slide 21, thereby changing the distance between the strapping machine 4 or the steel strip coil assembly 5 and the steel coil 8, which facilitates manual bundling.

[0031] 2. When the limiting plate 56 is perpendicular to the ground, the steel strip can be pulled out. The worker holds the movable end of the steel strip and wraps it around the steel coil 8 once. Then, a buckle is installed on the movable end of the steel strip. The strapping machine 4 is used to tighten the excess steel strip, bringing the steel strip close to the steel coil 8 to be packaged. Then, the two sides of the steel strip are connected by the buckle. Finally, the steel strip is cut, and the manual bundling of the steel coil 8 is completed. Then, the worker holds the handle 561 and pushes the limiting plate 56 towards the limiting seat 57, so that the limiting protrusion 583 leaves the limiting slot 571. Then, the handle 561 is rotated 90° so that the limiting plate 56 is parallel to the ground. After releasing the handle 561, under the action of the return spring 582, the limiting protrusion 583 is engaged in the limiting slot 571. At this time, the limiting plate 56 presses the steel strip against the limiting shaft 55, and the steel strip cannot be pulled out, which can prevent the movable end of the steel strip from retreating back onto the steel strip coil.

[0032] 3. When the steel strip is used up, use the electric hoist 6 to lower the position of the steel strip support plate 51, unscrew the cap 53, and remove the steel strip fixing cover 52. Put the new steel strip coil core on the support rod 54, and then engage the positioning groove 521 of the steel strip fixing cover 52 with the positioning protrusion 541 of the support rod 54. Tighten the cap 53 to complete the replacement of the steel strip coil 10.
