Description

Technical Field

[0001] The present invention belongs to the technical field of steel coil packaging, and in particular relates to a circumferential packaging device and a packaging method for steel coils. Background Art

[0002] Hot-rolled narrow strip steel, a key raw material in the steel processing industry, is experiencing growing market demand. Hot-rolled narrow strip steel production lines roll steel billets into strips meeting dimensional requirements. Vertical coilers then coil the finished strips into coils for delivery. To ensure smooth coil finishing and collection, as well as safe transportation, coil packaging is essential. The quality of the packaging significantly impacts the production efficiency of downstream processes and the stability of coil transportation.

[0003] Existing steel coil strapping equipment, whether using through-hole or circumferential strapping, uses steel strapping specifically designed for finished product packaging with a thickness of less than 1.2mm. The strapping is secured with a head-to-tail clip-on method. If thicker strapping is used, existing technology cannot achieve proper wrapping and tightening of the strapping. Furthermore, when thicker strapping is used, the head-to-tail clip-on method results in low connection strength at the clips. Strapping straps with a thickness of less than 1.2mm have limited strength, and the clip-on method offers poor stability. Consequently, strapping frequently breaks or disengages during downstream processing or transportation, causing the steel coils to loosen, disrupting normal production and wasting manpower and resources.

A linear bearing 110 matching the guide rod 109 is fixed on the clamping mounting plate 111. The guide rod 109 is installed on the inner side of the linear bearing 110. The linear bearing 110 plays a guiding role during the movement of the clamping mounting plate 111.

[0127] The height of the clamping roller 108 is greater than the height of the steel coil 7 to be processed, and the full-size steel coil can be clamped to ensure the clamping effect.

[0128] The conveying roller and the clamping roller 108 are both structural parts made of wear-resistant steel. The conveying roller and the clamping roller 108 made of wear-resistant steel have good wear resistance and extend the service life of the device.

[0129] The conveyor rollers in the conveyor roller group are provided with gears. The gears of adjacent conveyor rollers are meshed through connecting gears to achieve synchronous and unidirectional rotation of the conveyor rollers. The conveyor roller group includes a conveyor roller group 102 and a conveyor roller group 2 103. The drive assembly includes a motor 104 and a motor 2 105.

[0131] Working process of steel coil packaging and rotating transport device 1:

[0132] Steel coil conveying workflow:

[0133] Motor 1 104 drives the conveyor rollers in conveyor roller group 102 to rotate, and motor 2 105 drives the conveyor rollers in conveyor roller group 2 103 to rotate. The two rotate in the same direction. Conveyor roller group 102 and conveyor roller group 2 103 receive the steel coils transported by the upstream transport roller and continue to transport the steel coils downstream, or transport the steel coils to the center position of the steel coil packaging and rotating transport device 1 to wait for packaging.

[0134] Tightening steel coil workflow:

[0135] After the steel coil is transported to the center of the steel coil packaging and rotating transport device 1, the output shaft of the clamping cylinder 107 extends, pushing the two clamping mounting plates 111 toward each other, causing the clamping rollers 108 on the two clamping mounting plates 111 to clamp the steel coil 7 to be processed. Motor 1 104 and motor 2 105 are controlled to rotate in opposite directions. At this time, the conveyor rollers in conveyor roller group 102 and conveyor roller group 2 103 rotate in opposite directions, driving the steel coil 7 to be processed. Under the clamping action of the four clamping rollers 108, the outer ring of the steel coil is tightened. This tightening of the outer ring of the steel coil makes the packaged steel coil more secure.

[0136] Wrap and tighten the strapping belt 6 working process:

[0137] After the head of the strapping tape 6 is welded to the tongue and tail of the steel coil 7 to be processed, the output shaft of the tightening cylinder 107 extends, pushing the two clamping mounting plates 111 toward each other, causing the clamping rollers 108 on the two clamping mounting plates 111 to tightly grip the steel coil 7 to be processed. Motor 1 104 and motor 2 105 are controlled to rotate in opposite directions. At this time, the conveyor rollers in conveyor roller group 102 and conveyor roller group 2 103 rotate in opposite directions, driving the steel coil 7 to be processed to rotate. During the rotation of the steel coil, the clamping roller 108 presses the strapping tape 6 brought into the steel coil against the outer circumference of the steel coil, making it fit tightly. As the steel coil rotates, the strapping tape 6 is tightly wrapped around the outer circumference of the steel coil. This system can achieve the winding and tightening of thick strapping tape 6 with a thickness of 2mm-3mm during the steel coil packaging process, improving the quality of steel coil packaging.

[0138] By adjusting the rotation direction of motor 1 104 and motor 2 105 to control the same or opposite rotation directions of the conveyor rollers in conveyor roller group 1 102 and conveyor roller group 2 103, the transportation or rotation of the steel coil 7 to be processed can be achieved. The arrangement of the device is more compact and can be seamlessly connected with the steel coil transport roller line to achieve the transportation and rotation of the steel coil.

[0139] like Figures 7 to 9As shown, the steel coil packing tape 6 welding device 2 includes a welding base 201, a welding assembly 202, and a pressure wheel 203.

[0144] A welding slide 221 is fixed to the end surfaces of the welding base 201 and the inverted L-shaped guide plate 216 adjacent to the welding guide channel. Made of nylon, this material offers excellent wear resistance, extending the life of the device. Its smooth surface also reduces resistance to the movement of the pressing guide block 207.

A limit bolt 210 is correspondingly provided on the limit plate 215 and is threadedly connected to the limit mounting seat 209. The limit bolt 210 limits the movement of the welding assembly 202 and prevents the welding assembly 202 from being damaged. The stud of the limit bolt 210 limits the limit plate 215. A buffer 211 is fixed to the end of the stud adjacent to the limit plate 215. The buffer 211 acts as a buffer to prevent the limit bolt 210 from damaging the limit plate 215, making the limiting process more stable and reducing the shaking of the welding assembly 202.

[0149] Working process of steel coil strapping 6 welding device 2:

[0150] During each steel coil packaging process, the strapping tape 6 needs to be welded twice, the first welding of the strapping tape 6 head and the second welding of the strapping tape 6 tail. The specific working process of the strapping tape 6 welding device is as follows:

[0151] In step 1, when the head of the strapping tape 6 reaches the welding position, the output shaft of the clamping cylinder 107 extends, pushing the clamping wheel 203 to move in the direction of the steel coil. The clamping wheel 203 presses the head of the strapping tape 6 against the steel coil tongue. Then, the output shaft of the welding drive cylinder 107 extends, pushing the welding machine assembly toward the steel coil until the limit plate 215 on the welding machine assembly contacts the buffer 211 and is limited. At this time, the position sensor 2 receives the position signal of the limit plate 215, and the output shaft of the welding drive cylinder 107 stops. The welding machine assembly starts welding, welding the head of the strapping tape 6 to the steel coil tongue, and forming two corresponding welding points with the welding gun 20201-1 and the welding gun 20201-2 of the welding machine assembly.

[0152] Step 2: After welding is completed, the output shaft of the welding drive cylinder 107 contracts, pulling the welding machine assembly to reset. The position sensor detects the position signal of the limit plate 215, and the output shaft of the drive cylinder 107 stops contracting. The pressure wheel 203 keeps the strapping belt 6 pressed. The annular groove on the pressure wheel 203 prevents the strapping belt 6 from shifting up and down during the packaging process.

[0153] Step 3: When the tail of the strapping tape 6 reaches the welding position, the welding drive cylinder 107 repeats the action in step 1 to complete the welding of the tail of the strapping tape 6.

[0154] The welding process is simple and improves work efficiency compared to manual welding. The contact between the strapping tape 6 and the side wall of the steel coil is closer, which improves the welding strength and makes the connection between the strapping tape 6 and the steel coil tighter.

Every two vertical guide wheels 405 are correspondingly arranged to form a guide wheel group; a roller guide channel is formed between the two vertical guide wheels 405 of each guide wheel group; the strapping belt 6 moves in the roller guide channel, and the vertical guide wheel 405 and the flat guide wheel 403 rotate with the movement of the strapping belt 6, thereby reducing scratches on the strapping belt.

[0158] The roller guide channel of each guide wheel group is correspondingly provided with a flat guide wheel 403 group, and the flat guide wheel group includes two flat guide wheels 403, which are rotatably connected to the guide base 401.

[0191] Working process of steel coil packing and conveying device 4:

[0192] The strapping process involves preparatory work before feeding, which is only performed before the first wrapping or after replacing the strapping rolls. The outermost coil of the strapping roll is manually fed into the strapping feeder. The strapping head passes through the tensioning assembly 302, the strap length detection assembly 303, and the pinch assembly 304, until it reaches the cutting position of the strap cutting assembly 305. The handle in the tensioning assembly 302 is turned to move the active tensioning roller 30202 toward the fixed tensioning roller 30201, adjusting the gap between them and tightening the strapping roll 6. The handle in the strap length detection assembly 303 is turned to move the tensioning roller 30302 toward the detection roller 30301 until it presses the strapping roll 6 against the detection roller 30301. The output shaft of the cylinder 107 in the pinch assembly 304 is retracted, maintaining a certain opening between the active pinch roller 30402 and the driven pinch roller 30401 to allow the strap 6 to pass through. The output shaft of the hydraulic cylinder in the strap cutting assembly 305 is in a retracted state, and a certain gap is maintained between the movable cutting blade 30502 and the fixed cutting blade 30501 to allow the strapping belt 6 to pass through.

[0193] Tape feeding process:

[0194] The output shaft of the cylinder 107 in the pinch assembly 304 extends, pushing the pinch slide 30405 to move. This causes the driven pinch roller 30401 on the pinch slide 30405 to press the strapping tape 6 against the active pinch roller 30402. The servo motor then rotates the active pinch roller 30402, driving the strapping tape 6 forward and conveying it through the shear assembly 305 toward the steel coil. The tensioning assembly 302 clamps the strapping tape 6, creating a certain tension between the pinch assembly 304 and the tensioning assembly 302. This tension straightens the strapping tape 6, facilitating subsequent conveying. During the conveying of the strapping tape 6, the detection roller 30301 of the strap length detection assembly 303 rotates passively, and the encoder 30303 connected to it detects the conveyed length of the strapping tape 6 in real time. When the encoder 30303 detects that the conveying length of the strapping tape 6 reaches the set value, the clamping assembly 304 stops feeding the tape, and the output shaft of the hydraulic cylinder in the tape cutting assembly 305 extends, quickly pushing the movable cutting blade 30502 toward the fixed cutting blade 30501 to cut the strapping tape 6.

[0195] The machine can automatically feed thick strapping tape 6 continuously during the packaging process, automatically control the length of the strapping tape, and automatically cut the strapping tape, thus realizing the automation of the strapping process and greatly improving the efficiency of steel coil packaging.

[0203] Working process of steel coil strapping 6 feeding device 5:

[0204] Feeding operation process: The brake pad of the brake 507 is in the open state and does not brake the brake disc 506. The feeding disc 501 can rotate freely under the action of external force. When the steel coil is packaged, the belt feeding device pulls the strapping belt 6 to move at a constant speed. The strapping belt 6 is pulled by the strapping belt 6 and rotates together with the feeding disc 501. The strapping belt 6 is continuously released during the passive rotation process. The belt feeding device element transports the released strapping belt 6 to the packaging position.

The process of installing and disassembling the feed tray 501 is simple and convenient, which improves the work efficiency of replacing or replenishing 6 rolls of strapping tape.

[0208] The offline operation process of installing 6 rolls of strapping tape on the feeding tray 501 is as follows: first place 6 rolls of strapping tape on the feeding tray 501, fit the center hole of 6 rolls of strapping tape on the positioning boss 50101, turn the tightening bolt 505 to tighten the inner wall of the strapping tape 6, and fix the 6 rolls of strapping tape on the feeding tray 501. The process of installing 6 rolls of strapping tape is convenient and improves work efficiency.

[0209] The operation process of the packaging equipment is simple and automated

[0210] The strapping equipment uses thick steel strapping (6) with a thickness of 2-3mm to strap steel coils. The ends of the strapping strap (6) are welded to the ends of the steel coil tongue. The inherent strength of the thick strapping strap (6) and the welded attachment method provide a more secure and reliable strapping quality.
