Description

Technical Field

[0001] The utility model belongs to the technical field of steel material processing and packaging machinery, and in particular relates to an automatic paper storage and feeding device for steel coil packaging, which is suitable for paper feeding for steel coil packaging. Background Art

[0002] The coil wrapping machine is a widely used wrapping equipment in the metallurgical industry. According to the packaging requirements and the different types of materials, there are many types of this machine, including straight pull type, horizontal type, reciprocating type, straight travel type, tray type, turntable type, etc., but the core principle of the winding device is basically the same; it is widely used in the wrapping of copper strips, steel strips, steel coils, aluminum strips, bearings, steel wires, welding wires, cables, tires, hoses and other types of annular objects. After wrapping, the product not only looks beautiful, but also has good moisture-proof, dust-proof, rust-proof, anti-aging, and accidental damage-proof functions.

[0003] At present, the direct-pull winding machine is used to drive the paper tray to release the paper while the C ring rotates to wrap the paper. This paper release method has the following defects:

[0004] 1. When starting to wrap the paper, you must pull the paper tape (taking VCI paper as an example) close to the steel coil by hand, and start the C-ring winding of the direct-pull winding machine at the same time. This method is unsafe and poses a great safety hazard to the operator's limbs.

[0005] 2. When winding, if the operator pulls the paper close to the steel coil by hand but does not start the C ring first, and then starts the C ring winding after the operator takes his hand away, although this operation is relatively safe, the work efficiency is low and the output is affected.

[0006] 3. The straight-pull wrapping machine uses a C-ring to wrap and pull the rust-proof paper tray to feed the paper. The paper tray at this time is a reverse resistance to the tightness of the wrapped paper. This resistance also changes greatly due to the size of the paper tray and the speed of its stillness or rotation. The tightness of the wrapped paper tape will be inconsistent, and the paper may even break, resulting in an unsightly appearance of the product packaging.

[0007] 4. When the paper tape of the paper tray is not enough to wrap a steel coil, the remaining paper tape can only be discarded or half of the coil can be wrapped and then replaced with paper to continue wrapping. Doing so will either waste paper tape or time, resulting in increased production costs or reduced time efficiency. Utility Model Content

[0008] The utility model aims to provide an automatic paper storage and feeding device for steel coil packaging in view of the above problems existing in the prior art.

[0009] The above-mentioned purpose of the utility model is achieved by the following technical means:

[0010] An automatic paper storage and feeding device for steel coil packaging includes a paper tray installation device, a paper feeding device, a paper storage box and an automatic clamping and feeding device. The rust-proof paper tray is installed on the paper tray installation device. The rust-proof paper wrapped on the rust-proof paper tray is clamped by the paper feeding device and conveyed to the paper storage box for stacking. The rust-proof paper tape at the bottom of the paper storage box is pulled out of the paper storage box and bypasses a rotating roller. The automatic clamping and feeding device includes a longitudinal propulsion cylinder, a pneumatic chuck and a transverse propulsion cylinder. The fixed part of the longitudinal propulsion cylinder is arranged on the sliding part of the transverse propulsion cylinder. The fixed part of the pneumatic chuck is arranged on the sliding part of the longitudinal propulsion cylinder. The pneumatic chuck is located on the side of the rust-proof paper tape bypassing the rotating roller.

[0011] As described above, the paper tray installation device includes an expansion and contraction paper supporting shaft, a paper supporting shaft bearing seat, a paper release brake cylinder, a paper release brake disc and a paper release rotating shaft. The paper release rotating shaft is installed on the bracket through the paper supporting shaft bearing seat. The paper release rotating shaft is connected to the expansion and contraction paper supporting shaft axis. A paper release brake disc is also installed on the paper release rotating shaft. The paper release brake cylinder is connected to the brake pad, and the brake pad is located on the side of the paper release brake disc.

[0012] As described above, the paper feeding device includes a paper feeding motor, a paper pressing active wheel, a paper pressing passive wheel and a paper pressing double-rod cylinder. The paper feeding motor is fixed on a bracket, and the rotating shaft of the paper feeding motor is connected to the paper pressing active wheel. The rust-proof paper belt pulled out from the rust-proof paper tray is located between the paper pressing active wheel and the paper pressing passive wheel. The rotating shaft of the paper pressing passive wheel is movably arranged on the passive wheel bracket, the passive wheel bracket is connected to the telescopic part of the paper pressing double-rod cylinder, and the fixed part of the paper pressing double-rod cylinder is arranged on the bracket.

[0013] As mentioned above, the top of the paper storage box is open, and a distance sensor is arranged above the paper storage box.

[0014] As mentioned above, a visual window is provided on the side of the paper storage box.

[0015] An automatic paper storage and feeding device for steel coil packaging also includes a shearing device, which includes a paper cutting motor, a paper cutting head and a paper cutting seat. The paper cutting motor is connected to the paper cutting head, and the paper cutting head and the paper cutting seat are respectively located on both sides of the rust-proof paper belt.

[0016] Compared with the prior art, the utility model has the following beneficial effects:

[0017] 1. It can realize the automatic feeding of rust-proof paper tape in the packaging of steel coils, thus improving the transportation efficiency;

[0018] 2. In the automatic feeding of rust-proof paper tape, no manual intervention is required, reducing the risk of injury to workers;

[0019] 3. During the automatic feeding of the anti-rust paper tape, the anti-rust paper tape is buffered and stacked in the paper storage box. The anti-rust paper tray is not directly pulled during the steel coil packaging process, reducing the risk of the anti-rust paper tape breaking.

[0020] 4. The anti-rust paper tray is easy to replace. When installing a new anti-rust paper tray, just stick the anti-rust paper tape of the new anti-rust paper tray with the anti-rust paper tape in the paper box. This saves the use of anti-rust paper tape and can replace the anti-rust paper tray when the straight-pull winding machine is winding without stopping the machine. BRIEF DESCRIPTION OF THE DRAWINGS

[0026] In order to facilitate those skilled in the art to understand and implement the present invention, the present invention is further described in detail below in conjunction with embodiments. The embodiments described herein are only used to illustrate and explain the present invention and are not intended to limit the present invention.

[0027] An automatic paper storage and feeding device for steel coil packaging includes a paper tray installation device 1, a paper feeding device 2, a paper storage box 3 and an automatic clamping and feeding device 4. The rust-proof paper tray is arranged in the paper tray installation device 1. The paper tray installation device 1 is used to install the rust-proof paper tray. The rust-proof paper wound on the rust-proof paper tray is clamped and transmitted by the paper feeding device 2. The rust-proof paper tape on the rust-proof paper tray is fed into the paper storage box 3 through the paper feeding device 2 and stacked. Since the rust-proof paper tape is continuously fed into the paper storage box 3, the rust-proof paper tape is stacked from bottom to top in the paper storage box 3. The anti-rust paper tape at the bottom is pulled out of the paper box 3 from the side of the paper box 3 and bypasses the rotating roller 5. The automatic clamping and conveying device 4 includes a longitudinal propulsion cylinder 4-1, a pneumatic chuck 4-2, and a transverse propulsion cylinder 4-3. The fixed part of the longitudinal propulsion cylinder 4-1 is arranged on the sliding part of the transverse propulsion cylinder 4-3, the fixed part of the pneumatic chuck 4-2 is arranged on the sliding part of the longitudinal propulsion cylinder 4-1, the fixed part of the transverse propulsion cylinder 4-3 is arranged on the bracket, and the pneumatic chuck 4-2 is located on the side of the anti-rust paper tape bypassing the rotating roller 5.

[0028] When the broken end portion of the anti-rust paper tape is transmitted to the C-ring stage of the straight-pull winding machine: the longitudinal propulsion cylinder 4-1 drives the pneumatic chuck 4-2 to approach the broken end portion of the anti-rust paper tape that bypasses the rotating roller 5, and the pneumatic chuck 4-2 clamps the broken end portion of the anti-rust paper tape that bypasses the rotating roller 5. The transverse propulsion cylinder 4-3 drives the longitudinal propulsion cylinder 4-1 and the pneumatic chuck 4-2 to move transversely, thereby driving the broken end portion of the anti-rust paper tape to move transversely to the C-ring of the straight-pull winding machine, and the pneumatic chuck 4-2 releases the clamping of the anti-rust paper tape. The longitudinal propulsion cylinder 4-1 drives the pneumatic chuck 4-2 to retract, and the C-ring of the straight-pull winding machine uses the anti-rust paper tape to wrap the steel coil, and the transverse propulsion cylinder 4-3 drives the pneumatic chuck 4-2 back to the initial position, that is, the pneumatic chuck 4-2 is located on the side of the anti-rust paper tape that bypasses the rotating roller 5. The damage to human body caused by paper feeding during the movement of the C ring of the direct pull paper wrapping machine is reduced, and the conveying efficiency of the rust-proof paper belt is improved. The direct pull paper wrapping machine and its component C ring are both existing structures, and the utility model does not provide a detailed description of their structure.

[0029] As a preferred solution, an automatic paper storage and feeding device for steel coil packaging also includes a shearing device 6, which includes a paper cutting motor, a paper cutting head and a paper cutting seat. The paper cutting motor is connected to the paper cutting head, and the paper cutting head and the paper cutting seat are respectively located on both sides of the rust-proof paper tape. After the steel coil packaging is completed, the paper cutting motor pushes the paper cutting head toward the paper cutting seat to cut off the rust-proof paper tape, and then the paper cutting motor drives the paper cutting head to retract. After the paper cutting head retracts, the space between the paper cutting head and the paper cutting seat can be used for the pneumatic chuck 4-2 to pass through.

[0030] As a preferred solution, the paper tray installation device 1 includes an expansion and contraction paper supporting shaft 1-1, a paper supporting shaft bearing seat 1-2, a paper release brake cylinder 1-3, a paper release brake disc 1-4, and a paper release rotating shaft 1-5. The paper release rotating shaft 1-5 is installed on the bracket through the paper supporting shaft bearing seat 1-2. The paper release rotating shaft 1-5 is axially connected to the expansion and contraction paper supporting shaft 1-1. A paper release brake disc 1-4 is also installed on the paper release rotating shaft 1-5. The paper release brake cylinder 1-3 is connected to the brake pad, and the brake pad is located on the side of the paper release brake disc 1-4. The inner ring of the rust-proof paper tray is set on the expansion and contraction paper bearing shaft 1-1. The expansion and contraction paper bearing shaft 1-1 is an existing component and can achieve radial diameter change. After the inner ring of the rust-proof paper tray is set on the expansion and contraction paper bearing shaft 1-1, the radial size of the expansion and contraction paper bearing shaft 1-1 becomes larger, so that the rust-proof paper tray is fixed. When the rust-proof paper tray is removed, the radial size of the expansion and contraction paper bearing shaft 1-1 becomes smaller, and the rust-proof paper tray can be removed from the expansion and contraction paper bearing shaft 1-1. After the rust-proof paper tray is installed, the rust-proof paper belt is pulled out of the rust-proof paper tray under the drive of the paper feeding device 2, and the paper placing rotating shaft 1-5 is set in the inner ring of the paper bearing shaft bearing seat 1-2, so that the rust-proof paper tray can achieve self-rotation. When the paper feeding device 2 stops working, the paper release brake cylinder 1-3 drives the brake pad to brake the paper release brake disc 1-4, thereby braking the rotation of the rust-proof paper disc; when the paper feeding device 2 is working, the paper release brake cylinder 1-3 drives the brake pad to not brake the paper release brake disc 1-4, and the rust-proof paper disc can rotate.

[0031] As a preferred embodiment, the paper feeding device 2 includes a paper feeding motor 2-1, a paper pressing active wheel 2-2, a paper pressing passive wheel 2-3, and a paper pressing double-rod cylinder 2-4. The paper feeding motor 2-1 is fixed on a bracket, and the rotating shaft of the paper feeding motor 2-1 is connected to the paper pressing active wheel 2-2. The paper pressing active wheel 2-2 and the paper pressing passive wheel 2-3 are arranged opposite to each other and are located on both sides of the rust-proof paper belt pulled out from the rust-proof paper tray. The rotating shaft of the paper pressing passive wheel 2-3 is movably arranged on the passive wheel bracket, that is, the paper pressing passive wheel 2-3 can realize self-rotation, the passive wheel bracket is connected to the telescopic part of the paper pressing double-rod cylinder 2-4, and the fixed part of the paper pressing double-rod cylinder 2-4 is arranged on the bracket. When the paper feeding device 2 is working, the telescopic part of the paper pressing double-rod cylinder 2-4 is extended, and the paper pressing passive wheel 2-3 moves toward the paper pressing active wheel 2-2 until the rust-proof paper tape is clamped between the paper pressing passive wheel 2-3 and the paper pressing active wheel 2-2, and the paper releasing motor 2-1 works to drive the paper pressing active wheel 2-2 to rotate, and the rust-proof paper tape is pulled out from the rust-proof paper tray under the action of the friction force between the paper pressing passive wheel 2-3 and the paper pressing active wheel 2-2, and is transported to the paper storage box 3. Preferably, the outer surface of the paper pressing passive wheel 2-3 is provided with embossing.

[0032] The top of the paper storage box 3 is open, and a distance sensor is arranged on the top of the paper storage box 3. The distance sensor is used to measure the stacking height of the rust-proof paper tape in the paper storage box 3. When the stacking height is higher than the set height threshold, the paper feeding device 2 is controlled to stop working. A visual window is arranged on the side of the paper storage box 3 for observing the stacking height.

[0033] When the anti-rust paper disc is used up, the anti-rust paper disc is removed from the paper disc installation device 1, and a new anti-rust paper disc is installed, and the anti-rust paper tape of the new anti-rust paper disc is bonded to the anti-rust paper tape in the paper storage box 3. This saves the use of the anti-rust paper tape and can be carried out during the winding operation of the straight-pull winding machine without stopping the machine.

[0034] It should be noted that the embodiments described in the present invention are merely examples of the spirit of the present invention. Those skilled in the art of the present invention may make various modifications or additions to the embodiments described or replace them in similar ways, but they will not deviate from the spirit of the present invention or exceed the scope defined by the attached claims.
