The integrated hoop production equipment 100 provided by this application can sequentially cut, fold, and bend the steel strip to achieve integrated processing of hoops, improve production efficiency, and meet the needs of mass production of hoops of different sizes.

[0077] like Figure 1 As shown, an embodiment of this application provides an integrated hoop production equipment 100, which includes a cutting unit 120, a conveying unit 130, a folding unit 140, and a bending unit 150.

[0078] The cutting unit 120 is used to cut the steel strip into segments of a preset length. The input end of the conveying unit 130 is arranged adjacent to the cutting unit 120. The folding unit 140 is arranged adjacent to the output end of the conveying unit 130. The bending unit 150 is arranged adjacent to the output end of the folding unit 140. The cut steel strip is conveyed to the folding unit 140 through the output end of the conveying unit 130. The folding unit 140 folds up the edge of the steel strip and then conveys it to the bending unit 150. The bending unit 150 bends the folded steel strip multiple times to form a sleeve.

[0079] In some embodiments, the integrated hoop production equipment 100 further includes a base frame 160, on which a cutting unit 120, a conveying unit 130, a folding unit 140, and a bending unit 150 are sequentially mounted.

[0080] The base frame 160 includes a frame made up of multiple pipes and an installation platform plate located on the top side of the frame. Each unit is installed on the installation platform plate in sequence, and the output end of each unit is kept on the same straight line. The steel belt conveyor is fast and the feeding is convenient.

[0081] The base frame 160 can be installed as a single unit, with all units mounted on a unified base frame 160, or it can be installed in sections, with different units mounted on different base frames 160, and multiple base frames 160 can be spliced ​​together to form a whole. The base plate of the base frame 160 is also equipped with adjustable feet for adjusting the height of the base frame 160.

[0082] like Figure 9 As shown, in some embodiments, the folding unit 140 includes a fixing assembly 142 and a blade holder assembly 145 mounted on the base frame 160.

[0083] Combined Figure 11 As shown, the fixing assembly 142 includes a folded edge support 1421, a booster cylinder 1425, a side pressure cylinder 1426, an outer pressure plate 1427, a working plate 1428, and a fastening plate 1429.

[0084] The booster cylinder 1425 is installed on the top side of the folded edge support 1421, and the fastening plate 1429 is fixed to the output end of the booster cylinder 1425. In this embodiment, there are two booster cylinders 1425, and the two booster cylinders 1425 are respectively connected to the two ends of the fastening plate 1429.

[0085] The working plate 1428 is installed below the fastening plate 1429. The side pressure cylinder 1426 and the outer pressure plate 1427 are installed on the outside of the folding support 1421. The outer pressure plate 1427 is fixed to the output end of the side pressure cylinder 1426 and is adjacent to the outer side of the working plate 1428. An inner limiting component is provided on the side of the working plate 1428 away from the outer pressure plate 1427. When the steel strip is conveyed between the working plate 1428 and the fastening plate 1429, the side pressure cylinder 1426 is activated, driving the outer pressure plate 1427 to move closer to the working plate 1428. The outer pressure plate 1427 and the inner limiting component limit and fix both sides of the steel strip. Then, the booster cylinder 1425 is activated, driving the fastening plate 1429 to move downward, fixing the steel strip between the working plate 1428 and the fastening plate 1429.

[0086] The inner limiting assembly has at least two limiting wheel groups 134. Each limiting wheel is distributed along the inner side of the steel strip on the same straight line. The position of the limiting wheel is adjustable and cooperates with the outer pressure plate 1427 to form different distances, which can limit the steel strip of different widths to adapt to the folding of steel strips of various width specifications.

[0087] When the steel strip is threaded onto the working plate 1428, the outer pressure plate 1427 and the inner limiting assembly limit and fix the two sides of the steel strip. Then, driven by the booster cylinder 1425 and the side pressure cylinder 1426, the fastening plate 1429 presses the steel strip onto the working plate 1428. Then, the side pressure cylinder 1426 drives the outer pressure plate 1427 to reset, and the output end of the tool holder assembly 145 aligns with the edge of the fixed steel strip, folding up the edge of the steel strip.

[0088] Combined Figure 13 As shown, in some embodiments, the blade holder assembly 145 includes a base 1451, a folding cylinder 1452, a folding blade holder 1453, a folding blade 1454, and a slide rail 1455. The base 1451 is mounted on the bottom side of the fixing assembly 142. The folding cylinder 1452, the folding blade holder 1453, the folding blade 1454, and the slide rail 1455 are all mounted on the base 1451. There are two slide rails 1455, which are symmetrically arranged on both sides of the base 1451. The output end of the folding cylinder 1452 is fixed to the folding blade holder 1453. The folding blade holder 1453 is slidably connected to the slide rail 1455. The folding blade 1454 is fixedly mounted on the end of the folding blade holder 1453 away from the folding cylinder 1452.

[0089] The folding blade 1454 is mounted on the base frame 160 and aligned with the edge of the steel strip. After the steel strip is fixed by the fixing component 142, the folding cylinder 1452 drives the folding blade 1454 to move upward along the slide rail 1455, folding up the edge of the steel strip to complete the folding operation. After the steel strip is folded, the folding cylinder 1452 and the booster cylinder 1425 reset, and the steel strip is conveyed forward.

[0090] In some embodiments, the folding unit 140 further includes an active traction component 141, a driven traction component 143, and a guide component 144. The active traction component 141 and the driven traction component 143 are connected in a transmission manner and are located at both ends of the fixed component 142, respectively, for the input and output of the steel strip. The guide component 144 is disposed on the side of the driven traction component 143 away from the fixed component 142, for guiding the output of the steel strip.

[0091] The input side of the active traction component 141 is adjacent to the side of the conveying unit 130 away from the cutting unit 120. The driven traction component 143 is located between the fixed component 142 and the guide component 144. The driven traction component 143 is drively connected to the active traction component 141 and is used for the input and output of the steel belt, respectively. The fixed component 142 is disposed between the active traction component 141 and the driven traction component 143.

[0092] Combined Figure 10As shown, the active traction assembly 141 includes a guide seat 1411, a guide roller 1412, a first guide wheel group 1413, an active traction support 1414, a traction motor 1415, a third pressing cylinder 1416, a first metering wheel 1417, a third pressing roller 1418, and a third conveying roller 1419.

[0093] The guide seat 1411 and the active traction support 1414 are sequentially fixed on the base frame 160. The guide roller 1412 is mounted on the guide seat 1411 and is arranged adjacent to the output end of the conveying unit 130. The guide roller 1412 includes two rollers arranged at a relative distance to limit the vertical deviation of the steel belt. The first guide wheel group 1413 includes two guide wheels with adjustable spacing. The two guide wheels are arranged opposite to each other on both sides of the guide seat 1411. By adjusting the distance between the two guide wheels, steel belts of different widths can be limited. During the conveying process of the steel belt, the two guide wheels are distributed on both sides of the steel belt to limit the conveying direction of the steel belt and prevent the steel belt from deviating.

[0094] A traction motor 1415 is mounted on one side of the active traction support 1414. The output end of the traction motor 1415 is connected to the first conveying roller 1517 via a transmission structure, which can be a belt drive or a chain drive. Two third clamping cylinders 1416 are provided and mounted on the active traction support 1414. The output ends of the two third clamping cylinders 1416 are respectively connected to both ends of the third clamping roller. When the steel belt is guided by the first guide wheel group 1413 into the space between the third clamping roller and the third conveying roller 1419, the third clamping cylinder 1416 operates, driving the first clamping roller to move downward, thereby causing both sides of the steel belt to press against the first clamping roller and the first conveying roller 1517 respectively. At the same time, driven by the traction motor 1415, the first conveying roller 1517 rotates, thereby driving the steel belt forward to the fixed assembly 142. The first measuring wheel 1417 is installed on the side of the active traction support 1414 away from the guide seat 1411. During the steel belt conveying process, the steel belt abuts against the first measuring wheel 1417, thereby controlling the conveying length of the steel belt.

[0095] Combined Figure 12 As shown, the driven traction assembly 143 includes a driven traction support 1431, a fourth pressing cylinder 1432, a fourth pressing roller 1433, a fourth conveying roller 1434, and a transmission wheel 1435.

[0096] In this embodiment, the transmission wheel 1435 is a pulley and is connected to the traction motor 1415 via a belt. A tensioning wheel can also be provided to adjust the belt tension. After the steel strip is folded, it is conveyed between the second pressing roller 1534 and the second conveying roller 1539. The fourth pressing cylinder 1432 is activated, driving the second pressing roller 1534 to move downward, so that the steel strip is pressed between the second pressing roller 1534 and the second conveying roller 1539. Under the drive of the traction motor 1415, the second conveying roller 1539 rotates, driving the steel strip to the next process.

[0097] Combined Figure 11 As shown, the guide assembly 144 includes a second guide plate 1441, a second measuring wheel 1442, and a second guide wheel assembly 1443. The second guide plate 1441 is mounted on the base frame 160, and the second guide wheel assembly 1443 is mounted on one side of the second guide plate 1441. The position of the second guide wheel assembly 1443 is adjustable to accommodate different sizes of steel belts. The second measuring wheel 1442 is mounted on the side of the second guide plate 1441 near the driven traction assembly 143. After the steel belt is folded, it is output through the driven traction assembly 143, and the steel belt contacts the second measuring wheel 1442. During the conveying process, the steel belt sequentially contacts the first measuring wheel 1417 and the second measuring wheel 1442, achieving accurate measurement of the steel belt conveying.

[0098] In some embodiments, the fixing assembly 142 further includes an intermediate drive motor 1422, an intermediate clamping cylinder 1423, and an intermediate conveying roller assembly 1424. The intermediate conveying roller assembly 1424 is located on one side near the active traction assembly 141. The intermediate conveying roller assembly 1424 includes an upper conveying roller and a lower conveying roller arranged at a distance from each other. The intermediate drive motor 1422 is mounted on one side of the folding support 1421 and is connected to the lower conveying roller in a driving connection. The output end of the intermediate clamping cylinder 1423 is connected to the upper conveying roller. When the steel strip is conveyed to the intermediate conveying roller assembly 1424, the intermediate clamping cylinder 1423 operates, driving the upper conveying roller to move downward, thereby causing both sides of the steel strip to abut against the upper and lower conveying rollers respectively. At the same time, the intermediate drive motor 1422 drives the lower conveying roller to rotate, further ensuring the stable conveying of the steel strip.

[0099] In some embodiments, the folding unit 140 further includes a first positioning component 146, which is located between the active traction component 141 and the fixing component 142, and is used to position the front end of the steel strip to facilitate the measurement of the conveying length.

[0100] Combined Figure 14As shown, the first positioning component 146 includes a positioning cylinder 1461, a positioning plate 1462, and a guide plate 1463. The positioning cylinder 1461 and the guide plate 1463 are both mounted on the base frame 160. The output end of the positioning cylinder 1461 is fixedly connected to the positioning plate 1462. The positioning plate 1462 is located on the side of the guide plate 1463 that is close to the active traction component 141.

[0101] Before the folding operation, the positioning plate 1462 extends under the action of the positioning cylinder 1461. The steel belt is input through the active traction component 141. The front end of the steel belt is blocked by the positioning plate 1462 and abuts against the first measuring wheel 1417, serving as the starting length measurement point. After the steel belt aligns with the positioning plate 1462, the positioning cylinder 1461 drives the positioning plate 1462 to retract, and the steel belt continues to be conveyed to the fixing component 142. The steel belt passes through the active traction component 141, the first positioning component 146, and the fixing component 142 in sequence. After the folding is completed, the steel belt is output through the driven traction component 143 and the guide component 144, and abuts against the second measuring wheel 1442, realizing accurate measurement of the steel belt conveying during the folding process.

[0102] like Figure 15 As shown, in some embodiments, the bending unit 150 includes a bending assembly 153.

[0103] Combined Figure 18 As shown, the bending assembly 153 includes a bending support 1531, a second pressing cylinder 1532, a pressing plate 1533, a second pressing roller 1534, a second conveying roller 1539, a first bending roller 1535, a second bending roller 1536, a bending plate 1537, and a stop roller 1538.

[0104] The bending support 1531 is mounted on the base frame 160. The first bending roller 1535 and the second bending roller 1536 are arranged opposite each other on the same side of the bending support 1531. A bending motor and a synchronous pulley are mounted on the side of the bending support 1531 away from the second bending roller 1536. The output end of the bending motor is connected to the second bending roller 1536.

[0105] The bending plate 1537 has a U-shaped structure. The output shaft of the bending motor is connected to both the first bending roller 1535 and the bending plate 1537. The second bending roller 1536 is rotatably mounted on the bending plate 1537. Driven by the bending motor, the first bending roller 1535 and the bending plate 1537 rotate simultaneously, and the steel strip located between the first bending roller 1535 and the second bending roller 1536 is bent.

[0106] The stop roller 1538 is installed on the side of the bending support 1531 away from the bending assembly. During the bending process of the steel strip, the stop roller 1538 abuts against the inner side of the steel strip to prevent the steel strip from shifting.

[0107] In some embodiments, the bending unit 150 further includes a feeding assembly 151, which is disposed adjacent to the folding unit 140 and is used to convey the folded steel strip to the bending assembly 153.

[0108] Combined Figure 16 As shown, the feeding assembly 151 includes a feeding support 1511, a feeding motor 1512, a feeding roller 1513, a third guide wheel group 1514, a first clamping cylinder 1515, a first clamping roller 1516, a first conveying roller 1517, and a first tensioning roller 1518. The feeding support 1511 is mounted on the base frame 160. The feeding roller 1513 is arranged adjacent to the folding unit 140 and is used to limit the vertical offset of the steel strip. The third guide wheel group 1514 is located on the side of the feeding roller 1513 away from the folding unit 140. The second guide wheel includes two guide wheels with adjustable spacing. By adjusting the distance between the two guide wheels, the limiting requirements for steel strips of different widths can be met. The feeding motor 1512 is installed on one side of the feeding support 1511 and is connected to the first conveying roller 1517. The first pressing cylinder 1515 is installed on the top side of the feeding support 1511 and its output end is connected to the first pressing roller 1516. When the steel strip is conveyed between the first pressing roller 1516 and the first conveying roller 1517 via the feeding roller 1513 and the third guide wheel group 1514, the first pressing cylinder 1515 drives the first pressing roller 1516 to move downward, so that both sides of the steel strip abut against the first pressing roller 1516 and the first conveying roller 1517 respectively. At the same time, the feeding motor 1512 starts, driving the first conveying roller 1517 to rotate and conveying the steel strip to the next station.

[0109] The second pressing roller 1534 is positioned on the side of the first bending roller 1535 near the folding unit 140. A second conveying roller 1539 is positioned opposite the second pressing roller 1534. The second pressing cylinder 1532 is mounted on the top of the bending support 1531, and its output end is connected to the second pressing roller 1534. A synchronous pulley is coaxially arranged with the second conveying roller 1539 and is connected to the feeding motor 1512 via a belt. When the steel strip is conveyed to the second pressing roller 1534, the second pressing cylinder 1532 drives the second pressing roller 1534 downwards, causing the two sides of the steel strip to be respectively connected to the second pressing roller 1534 and the second conveying roller 1539. Simultaneously, driven by the bending motor and the synchronous pulley, the second conveying roller 1539 rotates, conveying the steel strip.

[0110] The feed support 1511 is also equipped with a first tensioning wheel 1518 on the side near the bending assembly 153. The tension of the belt between the feed motor 1512 and the second conveying roller 1539 is adjusted by the first tensioning wheel 1518.

[0111] In some embodiments, the bending unit 150 further includes a first guide component 152, which is disposed between the feeding component 151 and the bending component 153 for guiding the steel strip between the feeding component 151 and the bending component 153.

[0112] Combined Figure 17 As shown, the first guide assembly 152 includes a mounting plate 1521, a guide seat 1522, a third guide plate 1523, a fourth guide wheel assembly 1524, and a first limiting plate 1525. The mounting plate 1521 is fixed to the base frame 160 via the guide seat 1522. The third guide plate 1523 is installed in the middle of the mounting plate 1521 to serve as a conveying channel for the steel strip. The fourth guide wheel assembly 1524 includes two guide wheels with adjustable spacing. The two guide wheels are installed on both sides of the third guide plate 1523. By adjusting the distance between the two guide wheels, the limiting requirements for steel strips of different widths can be met. The first limiting plate 1525 is disposed at one end of the mounting plate 1521 near the feeding assembly 151. In this embodiment, there are two first limiting plates 1525, which are arranged opposite to each other on both sides of the mounting plate 1521. The two first limiting plates 1525 are open and play a role in limiting and guiding the steel strip so that the steel strip can pass through the first guide assembly 152.

[0113] In some embodiments, the bending unit 150 further includes a second positioning component 154, which is positioned on the side of the bending component 153 away from the first guide component 152, for accurately positioning the bending distance of the steel strip.

[0114] Combined Figure 19 As shown, the second positioning component 154 is disposed at the output end of the bending component 153. The second positioning component 154 includes a support plate 1541, a guide rod cylinder 1542, a connecting plate 1543, a first blocking plate 1544, a second blocking plate 1545, an adjusting component 1546, and a control switch 1547.

[0115] Both the guide rod cylinder 1542 and the support plate 1541 are mounted on the base frame 160. The output end of the guide rod cylinder 1542 is connected to the connecting plate 1543. The first blocking plate 1544 is mounted on the connecting plate 1543. Driven by the guide rod cylinder 1542, the first blocking plate 1544 moves up and down. The support plate 1541 is mounted above the connecting plate 1543, with reserved space for the lifting and lowering of the connecting plate 1543. The first blocking plate 1544 has a waist-shaped groove, and the position of the first blocking plate 1544 on the connecting plate 1543 is adjusted by the cooperation of the waist-shaped groove and bolts.

[0116] The second blocking plate 1545 is installed on the top side of the support plate 1541. The adjusting member 1546 is connected to the second blocking plate 1545 and controls the movement of the second blocking plate 1545. The control switch 1547 is installed on the second blocking plate 1545. In this embodiment, the adjusting member 1546 is a manual slide, and the second blocking plate is fixed to the slider of the manual slide.

[0117] When the top of the steel strip contacts the first stop plate 1544, the feed motor 1512 stops rotating, and the steel strip stops moving forward. The steel strip is fixed by the first pressure roller 1516 and the second pressure roller 1534. The bending motor drives the bending plate 1537 and the first bending roller 1535 to rotate, performing the first bending of the steel strip. After the first bending is completed, the top of the steel strip is in a raised state.

[0118] After the first bend, the feed motor 1512 starts, and the steel strip is fed forward again. When the top of the steel strip contacts the control switch 1547, the bending motor starts to bend the steel strip again. After multiple bending operations, the straight steel strip is bent into a rectangular frame.

[0119] In some embodiments, the cutting unit 120 includes a corner-cutting device 121 and a cutting device 123. The corner-cutting device 121 is used to cut a corner on a preset portion of the steel strip to obtain a corner notch, and the cutting device 123 cuts the steel strip along the baseline of the corner notch.

[0120] like Figure 3 As shown, in some embodiments, the corner-cutting device 121 includes a corner-cutting mounting base 1216, a first pressure plate 1215, a lower cutter 1214, a corner-cutting cylinder 1211, a first connector 1212, and an upper cutter 1213. The corner-cutting mounting base 1216 is fixed on the base frame 160. The first pressure plate 1215 and the lower cutter 1214 are both mounted on the corner-cutting mounting base 1216. The corner-cutting cylinder 1211 is located on the side of the lower cutter 1214 away from the corner-cutting mounting base 1216. The first connector 1212 is fixed to the output end of the corner-cutting cylinder 1211. The upper cutter 1213 is mounted on the first connector 1212. A gap is left between the first pressure plate 1215 and the corner-cutting mounting base 1216 for the steel strip to pass through. Under the shearing cooperation of the upper cutter 1213 and the lower cutter 1214, the preset part of the steel strip forms a corner notch.

[0121] Specifically, through the setting of the first pressure plate 1215, when the steel strip is conveyed to the corner cutting device 121, the steel strip is restricted between the first limiting plate and the corner cutting mounting seat 1216 to facilitate the corner cutting operation. The upper cutter 1213 and the lower cutter 1214 are both distributed on the same side of the steel strip and are staggered. During the corner cutting process, the corner cutting cylinder 1211 pushes the upper cutter 1213 downward. The downward movement of the upper cutter 1213 and the lower cutter 1214 form an interlaced shearing force, cutting off a corner on one side of the steel strip to form a corner notch. After the corner cutting is completed, the corner cutting cylinder 1211 retracts, the upper cutter 1213 resets, and the steel strip can continue to be conveyed to the next process.

[0122] Combined Figure 5 As shown, the cutting device 123 includes a cutting mounting base 1236, a first guide plate 1234, a lower cutting blade 1235, a cutting cylinder 1231, a second connector 1232, and an upper cutting blade 1233. The cutting mounting base 1236 is fixed on the base frame 160. The first guide plate 1234 is mounted on the cutting mounting base 1236. The lower cutting blade 1235 is fixedly connected to the first guide plate 1234. The cutting cylinder 1231 is located on the side of the lower cutting blade 1235 away from the cutting mounting base 1236. The second connector 1232 is fixed to the output end of the cutting cylinder 1231. The upper cutting blade 1233 is mounted on the second connector 1232. The upper cutting blade 1233 and the lower cutting blade 1235 are staggered to cut the steel strip.

[0123] Specifically, two first guide plates 1234 are provided and are positioned opposite each other on both sides of the lower cutting blade 1235. The two sides of the lower cutting blade 1235 are fixed to the two first guide plates 1234 by bolts, and its blade back abuts against the cutting mounting base 1236, with the blade edge facing the blade edge of the upper cutting blade 1233. After the steel strip is punched, the steel strip is conveyed to the channel between the two first guide plates 1234, and the bottom side of the steel strip abuts against the lower cutting blade 1235. When the cut corner of the steel strip is located between the upper cutting blade 1233 and the lower cutting blade 1235, the cutting cylinder 1231 drives the upper cutting blade 1233 to move downward. Due to the staggered distribution of the upper cutting blade 1233 and the lower cutting blade 1235, the downward movement of the upper cutting blade 1233 and the lower cutting blade 1235 form an interlaced shearing force, cutting the steel strip along the cut corner. After the cutting is completed, the cutting cylinder 1231 retracts, the upper cutting blade 1233 resets, and the steel strip can continue to be conveyed to the next process.

[0124] like Figure 6 As shown, in some embodiments, a limiting groove 1237 is formed on the contact side of the first guide plate 1234 and the lower cutting blade 1235, and the upper cutting blade 1233 passes through the limiting groove 1237.

[0125] Specifically, the limiting groove 1237 and the lower cutting blade 1235 are arranged adjacent to each other. The lower cutting blade 1235 serves as one side wall of the limiting groove 1237, so that when the upper cutting blade 1233 passes through the limiting groove 1237, the upper cutting blade 1233 and the lower cutting blade 1235 come into contact. The cutting edges of both the upper cutting blade 1233 and the lower cutting blade 1235 correspond to the uniform cutting line of the steel strip, completing the cutting operation. The limiting groove 1237 prevents the upper cutting blade from deviating during movement, ensuring the cutting efficiency and quality of the steel strip.

[0126] In some embodiments, the cutting unit 120 further includes a punching device 122, which is disposed between the corner cutting device 121 and the cutting device 123.

[0127] Combined Figure 4 As shown, the punching device 122 includes a punching mounting base 1226, a second pressure plate 1225, a lower punching cutter 1224, a punching cylinder 1221, a third connector 1222, and an upper punching cutter 1223. The punching mounting base 1226 is fixed on the base frame 160. The second pressure plate 1225 and the lower punching cutter 1224 are mounted on the punching mounting base 1226. The punching cylinder 1221 is located on the side of the lower punching cutter 1224 away from the punching mounting base 1226. The third connector 1222 is fixed to the output end of the punching cylinder 1221. The upper punching cutter 1223 is mounted on the third connector 1222. A gap is left between the second pressure plate 1225 and the punching mounting base 1226 for the steel strip to pass through. Under the impact cooperation of the upper punching cutter 1223 and the lower punching cutter 1224, a through hole is formed at the preset point of the steel strip.

[0128] Specifically, through the setting of the second pressure plate 1225, when the steel strip is conveyed to the punching device 122, the steel strip is restricted between the second limiting plate and the punching mounting base 1226 to facilitate the punching operation. The second limiting plate has a channel for the upper punching cutter 1223 to pass through. With the steel strip restricted between the second limiting plate and the lower punching cutter 1224, during the punching process, the punching cylinder 1221 pushes the upper punching cutter 1223 downwards. The downward movement of the upper punching cutter 1223 and the lower punching cutter 1224 create an alternating shearing force, impacting the preset point of the steel strip to form a through hole. After punching is completed, the punching cylinder 1221 retracts, the upper punching cutter 1223 resets, and the steel strip can continue to be conveyed to the next process.

[0129] Based on the dimensions of the hoop product, a suitable steel strip length can be selected as the cutting point. The corner-cutting device 121 marks the cutting point on the steel strip to facilitate subsequent drilling and cutting positioning. After corner cutting, the steel strip is conveyed to the punching device 122. Punching points are set based on the distance between the hole positions and the edge of the steel strip, using the corner as a reference. Depending on the required number of holes, the punching device 122 can continuously punch different parts of the steel strip during conveying to form multiple intermittent punches. After punching, the steel strip continues to be conveyed to the cutting device 123. When the corner is conveyed to the blade of the cutting device 123, the cutting device 123 cuts along the corner notch reference line, completing the fixed-length cutting of the steel strip.

[0130] In some embodiments, the integrated hoop production equipment 100 further includes a straightening and pressing unit 110, which has an input end and an output end. The steel strip passes through the straightening and pressing unit 110 via the input end. The straightening and pressing unit 110 straightens and presses the steel strip and outputs it from the output end. The corner cutting device 121 is arranged adjacent to the output end of the straightening and pressing unit 110.

[0131] Specifically, the steel strip retains its bending toughness during the unwinding process. The steel strip enters through the input end of the straightening and forming unit 110. After being straightened by the straightening component of the straightening and forming unit 110, the steel strip is in a straight state. After being further processed by the forming component, the steel strip is pressed into a preset shape and output to the corner cutting device 121 through the output end of the straightening and forming unit 110.

[0132] Combined Figure 2 As shown, the straightening and forming unit 110 includes a second guide assembly 112, a straightening roller group 116, a forming roller group 117, and a drive motor 118. The second guide assembly 112 is located at the input end of the straightening and forming unit 110 and is used to limit the conveying direction of the steel strip. Simultaneously, the second guide assembly 112 can adjust the spacing of the guide wheels according to the width of the steel strip to achieve the limiting and guiding function of steel strips of different widths. The second guide assembly 112 is located on one side of the straightening roller group 116, and the forming roller group 117 is located on the other side. The drive motor 118 is connected to both the straightening roller group 116 and the forming roller group 117.

[0133] In some embodiments, the second guide assembly 112 includes a fifth guide wheel group 1121 and a sixth guide wheel group 1122. The fifth guide wheel group 1121 is used to limit the vertical height of the steel belt, and the guide width of the sixth guide wheel group 1122 is adjustable to limit the horizontal conveying direction of steel belts of different widths. The fifth guide wheel group 1121 consists of upper and lower guide wheels arranged opposite each other, forming a gap between the upper and lower guide wheels to facilitate the conveying of the steel belt. There are multiple sixth guide wheel groups 1122, each of which includes two guide wheels arranged on both sides, and the distance between the two guide wheels is adjustable. This allows for limiting the movement of steel belts of different widths. During the conveying process of the steel belt, the two guide wheels are distributed on both sides of the steel belt to limit the conveying direction of the steel belt and prevent the steel belt from deviating and failing to be conveyed to the next processing unit.

[0134] In one embodiment, a pressing roller group 115 is provided on the connection side between the straightening roller group 116 and the second guide assembly 112. The pressing roller group 115 includes an adjustable upper pressing roller and a fixed roller corresponding to the upper pressing roller. An adjusting cylinder 114 is provided above the upper pressing roller. By adjusting the extension and retraction of the output end of the adjusting cylinder 114, the upper pressing roller is driven to move closer to the fixed roller. After the steel strip is guided to the pressing roller group 115 by the second guide assembly 112, the adjusting cylinder 114 pushes the lower pressing roller to press the steel strip against the fixed roller. Under the action of the drive motor 118, the fixed roller and the lower pressing roller rotate, conveying the steel strip to the straightening roller group 116.

[0135] In one embodiment, multiple straightening roller groups 116 can be provided to improve the straightening strength of the steel strip. Each straightening roller group 116 includes an upper straightening roller and a lower straightening roller, with a channel for the steel strip to pass through between the upper and lower straightening rollers. Both the upper and lower straightening rollers are in contact with both sides of the steel strip, and under the drive of the drive motor 118, the upper and lower straightening rollers rotate and straighten the steel strip.

[0136] In one embodiment, the forming roller group 117 and the straightening roller group 116 are arranged adjacent to each other. Multiple forming roller groups 117 can also be provided to improve the forming effect of the steel strip. Each forming roller group 117 includes an upper forming roller and a lower forming roller. The upper forming roller and the lower forming roller are provided with protrusions and depressions for pressing and forming. The upper forming roller and the lower forming roller rotate under the drive of the drive motor 118 to press the straightened steel strip into a preset shape.

[0137] In some embodiments, the straightening and forming unit 110 further includes a frame 111 mounted on a base frame 160, and a second guide assembly 112 disposed at one end of the frame 111. The pressing roller group 115, the straightening roller group 116, and the forming roller group 117 are all mounted on the frame 111. The end of the frame 111 where the pressing roller group 115 is mounted is also provided with a groove for adjusting the output end of the cylinder 114 to pass through. The frame 111 is used to fix and spatially position each component.

[0138] In some embodiments, a drive motor 118 is mounted on one side of a frame 111, and a plurality of gears 113 are mounted on the side of the frame 111 away from the drive motor 118, all of which mesh with each other. The pressing roller group 115, the straightening roller group 116, and the forming roller group 117 are fixedly connected to different gears 113, respectively. The output shaft of the drive motor 118 is connected to one of the gears 113. Through the transmission of the gears 113, the drive motor 118 drives the pressing roller group 115, the straightening roller group 116, and the forming roller group 117 to rotate, thereby realizing the feeding, straightening, and forming operations of the steel strip.

[0139] In some embodiments, the integrated production equipment 100 for sleeve clamps further includes a conveying unit 130, which is disposed on the side of the cutting device 123 away from the punching device 122, for conveying the cut steel strip to the folding unit 140.

[0140] Combined Figure 7 As shown, the conveying unit 130 includes multiple drive components 131, a receiving plate 133, a limiting wheel set 134, and a second limiting plate 132. The drive components 131 are mounted on the base frame 160. The two ends of the receiving plate 133 are respectively connected to two adjacent drive components 131. The limiting wheel set 134 is mounted on both sides of the receiving plate 133. The limiting width of the limiting wheel is adjustable to limit steel strips of different widths. The second limiting plate 132 is fixed to the middle of the receiving plate 133, and a channel for the steel strip to pass through is preset between the second limiting plate 132 and the receiving plate 133.

[0141] Specifically, the number of drive assemblies 131 can be two, three, four, etc., and can be reasonably set according to the length of the steel belt and the site requirements. A receiving plate 133 is provided between each pair of adjacent drive assemblies 131 for the transmission of the steel belt. In this embodiment, the number of drive assemblies 131 is three.

[0142] Each receiving plate 133 is provided with at least one second limiting plate 132. A gap is left between the second limiting plate 132 and the receiving plate 133 for the passage of the steel belt. The two ends of the second limiting plate 132 are raised relative to the middle to form an opening structure, facilitating the entry and exit of the steel belt. Multiple limiting wheel sets 134 are provided, and each limiting wheel set 134 includes limiting wheels disposed on both sides of the load-bearing plate.， The spacing between each set of limit wheels is adjustable to limit steel strips of different widths. The second limit plate 132 limits the vertical offset of the steel strip. Adjusting the spacing between each set of limit wheels allows for limiting steel strips of different widths. During the conveying process, the two limit wheels are distributed on both sides of the steel strip to restrict its conveying direction, preventing deviation and ensuring it can be conveyed to the next processing unit.

[0143] The end of the steel strip enters the conveying unit 130 via the drive assembly 131 closest to the cutting device 123, passes through the drive assembly 131 in the middle in sequence, and is finally output via the drive assembly 131 furthest from the cutting device 123.

[0144] like Figure 8 As shown, in some embodiments, the drive assembly 131 includes a drive support 1314, a driven conveying roller 1312, an active conveying roller 1313, and a pressing cylinder 1311. The drive support 1314 is fixedly mounted on the base frame 160. The driven conveying roller 1312 and the active conveying roller 1313 are both rotatably mounted on the drive support 1314. Two pressing cylinders 1311 are provided and relatively fixed on the side of the drive support 1314 away from the base frame 160.
