Description
Technical Field
[0001] This utility model relates to a packaging device, and more particularly to a device that can assist workers in wrapping packaging straps around the outer wall of a steel coil, belonging to the technical field of steel coil auxiliary packaging equipment. Background Technology
[0002] Steel coils need to be packaged before leaving the factory to ensure they don't unravel during transport. Currently, the packaging is done manually. Workers pull the end of the strapping, winding it around the coil, and then use a handheld strapping machine to secure it. During this process, the strapping is coiled, and when needed, the end is manually pulled to extend the required length, winding it around the coil before packaging. This process is time-consuming, labor-intensive, and inefficient. The manual pulling of the strapping is strenuous, and each loop of strapping requires manual winding around the coil, further extending packaging time and slowing production. Therefore, a device is needed to assist workers in pulling the strapping and quickly winding it around the coil, thereby improving packaging efficiency. Utility Model Content

[0015] See Figure 1 and Figure 2 This utility model includes a strapping band limiting part, a lifting part, a winding part, and a pulling part; the strapping band limiting part is used to hold the strapping band roll, ensuring that it can be smoothly released; there are two lifting parts, which are symmetrically arranged on both sides of the winding part; the lifting parts are used to drive the winding part to rise and fall, thereby ensuring that the winding part can be smoothly fitted onto the outer ring of the steel coil or leave the steel coil; the pulling part is arranged on the winding part; the pulling part is used to pull the strapping band, ensuring that the strapping band can move along the winding part until the strapping band smoothly wraps around the target steel coil; the strapping band limiting part is set on the ground, and the strapping band is placed inside the strapping band limiting part.
[0016] The strapping band limiting section includes a bottom disc 1, a top disc 2, a turntable 3, a center rod 4, and a rotating roller 5. Multiple casters are evenly distributed on the bottom surface of the bottom disc 1. The bottom end of the center rod 4 is located at the center of the top surface of the bottom disc 1. The turntable 3 has a hole in its center, through which the center rod 4 passes. Multiple omnidirectional balls are provided on the bottom surface of the turntable 3, and these balls press against the top surface of the bottom disc 1. The strapping band roll has a hole in its center, allowing the center rod 4 to pass directly through and rest on the turntable 3 during installation. When the strapping band is pulled, it rotates. The presence of the turntable 3 ensures that it rotates along with the strapping band, and the omnidirectional balls minimize the impact on the turntable 3's rotation. Rotational friction ensures that the force required to pull the strapping is as small as possible; there are multiple rotating rollers 5, which are evenly arranged along the circumferential direction of the bottom disc 1 at the edge of the top surface of the bottom disc 1, and the bottom end of the rotating roller 5 is axially connected to the top surface of the bottom disc 1; the function of the rotating roller 5 is to prevent the strapping roll from detaching and to reduce the friction between the strapping roll and the rotating roller 5 during rotation. The rotating roller 5 can rotate, which reduces the friction on the outer edge of the strapping roll to a certain extent when it rotates; the top disc 2 has a hole in the center, and the center rod 4 passes through the center hole of the top disc 2, and the top disc 2 presses against the top of the rotating roller 5; the function of the top disc 2 is to prevent the strapping roll from detaching from the strapping restraint part during use.
[0017] The winding section includes a semi-circular guide plate 6, a semi-circular baffle 7, and electric cylinders 8. The arc-shaped inner wall of the semi-circular guide plate 6 has a guide groove along its arc-shaped trajectory. The channel for the packing strap to subsequently wind around the steel coil is the arc-shaped guide groove. The packing strap slides within the guide groove of the semi-circular guide plate 6 until the end of the packing strap smoothly winds around the steel coil more than half a turn. There are multiple electric cylinders 8, all located on the top surface of the outer wall of the semi-circular guide plate 6, and the end of the piston rod of each electric cylinder 8 is connected to the semi-circular baffle 7. The top surface is connected, and the axis of the piston rod of the electric cylinder 8 and the axis of the semi-circular baffle 7 are both perpendicular lines; the arc-shaped outer wall of the semi-circular baffle 7 presses against the arc-shaped inner wall of the semi-circular guide plate 6; when the piston rod of the electric cylinder 8 is in the retracted state, the semi-circular baffle 7 blocks the guide groove of the semi-circular guide plate 6. In this state, the packing strap can move smoothly around the guide groove and will not detach from the guide groove of the semi-circular guide plate 6; the axis of the semi-circular baffle 7 and the axis of the semi-circular guide plate 6 coincide.
[0018] The strapping section includes a horizontal plate 9, a square frame 10, strapping components, and a square limiting cylinder 11. The horizontal plate 9 is located at one end of the bottom surface of the semi-circular guide plate 6. The square frame 10 is located at the end of the horizontal plate 9 away from the semi-circular guide plate 6. There are two strapping components, both of which are located on the square frame 10. The square limiting cylinder 11 is located at the end of the square frame 10 away from the semi-circular guide plate 6 via a bracket. The square limiting cylinder 11 provides guidance for the strapping, ensuring that it can enter between the two strapping components.
[0019] The strapping component includes a motor 12 and a clamping roller 13; the motor 12 is disposed on the top surface of the square frame 10, and its output shaft passes through the side wall of the square frame 10; the end of the output shaft of the motor 12 is connected to the top of the clamping roller 13, and the bottom end of the clamping roller 13 is axially connected to the bottom end face of the inner wall of the square frame 10; the strapping is clamped between the two clamping rollers 13; when the motor 12 drives the clamping roller 13 to rotate, the strapping held between the two rotating clamping rollers is clamped and moved forward, and the end of the strapping is pushed forward to move around the guide groove of the semi-circular guide plate 6, and then around the steel coil.
[0020] Two lifting sections are respectively connected to both ends of the arc-shaped outer wall of the semi-circular guide plate 6; the lifting section includes a base plate 14, a guide cylinder 15, a lifting rod 16, a hydraulic cylinder 17, and a top plate 18; universal wheels are provided at the four corners of the bottom end face of the base plate 14; the guide cylinder 15 is located at one end of the top end face of the base plate 14, and a counterweight is provided at the other end of the top end face of the base plate 14; the lifting rod 16 is inserted into the hole at the top end of the guide cylinder 15; the hydraulic cylinder 17 is located on the outer wall of the guide cylinder 15, and the end of its piston rod is connected to the top end of the lifting rod 16; the hydraulic cylinder 17 can reliably drive the lifting rod 16 to rise and fall; the top plate 18 is located on the top end face of the lifting rod 16; the top plate 18 is connected to one end of the arc-shaped outer wall of the semi-circular guide plate 6 through a bracket.
[0021] Operating principle:
[0022] When the packing tape is used up, the replenishment steps are as follows: lift the top disc 2 and place the new packing tape roll on the turntable 3. The center rod 4 passes through the center hole of the packing tape roll. Then cover the top disc 2 and pull the end of the packing tape to the square limiting cylinder 11, so that the end of the packing tape passes between the two clamping rollers 13 and extends into the end opening of the semi-circular guide plate.
[0023] When it is necessary to pack the steel coil, push the device to move it in front of the steel coil, or wait for the steel coil to move directly under the semi-circular guide plate. Once the steel coil is directly under the semi-circular guide plate 6, start the hydraulic cylinder 17 to drive the lifting rod 16 to descend. The descent of the lifting rod 16 will also drive the semi-circular guide plate 6 to descend until the semi-circular guide plate 6 is in a suitable position outside the steel coil. Then stop the action of the hydraulic cylinder 17, and start the two motors 12 to drive the two clamping rollers 13 to rotate, driving the end of the packing strap forward. The packing strap moves along the guide groove of the semi-circular guide plate until the end of the packing strap extends out from the other end of the guide groove of the semi-circular guide plate. Then start the electric cylinder 8, and the semi-circular baffle 7 moves upward, exposing the packing strap. The worker holds the packing strap with one hand. At the end of the strapping strap, the other hand holds a portion of the strapping strap located between the clamping roller and the end of the semi-circular guide plate, pulling the strapping strap out from the semi-circular guide plate. At this time, the strapping strap surrounds the steel coil. The worker holds the strapping machine and uses it to bundle and pack the steel coil. After the strapping machine finishes its operation, the strapping strap is cut off, and the cut-off part is already wrapped around the steel coil. Then the worker inserts the end of the strapping strap back into the guide groove of the semi-circular guide plate, and controls the electric cylinder 8 to reset, causing the semi-circular baffle 7 to block the guide groove of the semi-circular guide plate again. Then the hydraulic cylinder moves upward, and the semi-circular guide plate leaves the steel coil. Then wait for the next steel coil to move to the underside of the semi-circular guide plate, and then repeat the above actions. Repeat this process to bundle and pack each steel coil.
