[0027] Example 1: Please refer to Figure 1 , Figure 2 and Figure 4A roller assembly with a quick-release structure is disclosed. Each roller includes a roller body 1 and a quick-release structure, wherein the quick-release structure adopts a modular design. The quick-release structure includes a first mounting base 3, a baffle 2, a slot 6, and a limiting groove 7. The first mounting base 3 is rotatably connected to one end of the roller body 1, and the other end of the roller body 1 is rotatably connected to the slot 6. The baffle 2 is fixedly installed at the connection between the first mounting base 3 and the roller body 1. The inner wall of the slot 6 has a vertically opened limiting groove 7. The quick-release structure enables the roller assembly to be quickly disassembled on the workbench 10.

[0028] The roller assembly is mounted on the workbench 10. One end of the workbench 10 has a groove that matches the first mounting seat 3, and the other end of the workbench 10 is mounted on the second mounting seat 15. The second mounting seat 15 includes: a slider 16, a slide rail 17, a limiting strip 18, an electromagnetic fixing block 19, and a second motor 20. The slide rail 17 is fixedly mounted inside the second mounting seat 15. An electromagnetic fixing block 19 is fixedly mounted on one end of the slide rail 17. The slider 16 is movably mounted on the slide rail 17. The slider 16 matches the slot 6. A limiting strip 18 that matches the limiting slot 7 is mounted on the side of the slider 16. The slider 16, the slide rail 17, the limiting strip 18, and the electromagnetic fixing block 19 are all made of high-strength alloy steel. The second motor 20 is connected to the other end of the slide rail 17. The second motor 20 drives the slider 16 to slide on the slide rail 17 to fix the slot 6.

[0029] The workbench 10 is equipped with a first motor 11 on one side and a movable driven gear 14 on the other side. The output end of the first motor 11 is connected to a drive shaft 12. The other end of the drive shaft 12 is fixedly equipped with a driving gear 13. The driving gear 13 and the driven gear 14 mesh with the teeth 5 on the roller 4.

[0030] Furthermore, in continuous rolling production lines for metal sheets, the traditional method of replacing roller sets in hot-rolled steel plate production lines requires stopping the machine to disassemble the bolt structure, taking an average of 45 minutes. This quick-release roller set, however, is used. The production line is equipped with 24 roller sets 1, each with a diameter of φ200 mm × 1500 mm. Each roller set 1 has a 12 mm deep limiting groove 7 on its inner wall of the slot 6. When the third roller set 1 needs replacement due to high-temperature deformation, the operator triggers the second motor 20 (0.75 kW) inside the second mounting base 15, driving the slider 16 to retract 100 mm along the slide rail 17 made of high-strength 42CrMo alloy steel. The operating voltage is 24... When the electromagnetic fixing block 19 of the VDC is de-energized, it releases its magnetic attraction. At this time, the operator removes the deformed roller and aligns the cylindrical head structure of the first mounting seat 3 of the new roller (50mm in diameter) with the cylindrical groove at the end of the workbench 10. The roller 1 falls at a 15-degree angle, and the slot 6 automatically embeds into the base of the slider 16. The second motor 20 drives the slider 16 forward in the opposite direction, and the limiting strip 18 (10mm × 8mm in cross-section) is precisely inserted into the limiting groove 7 to achieve radial locking. At the same time, the electromagnetic fixing block 19 is energized to generate a 1500 N attraction force to complete axial fixing, which greatly shortens the time for changing rollers. After the production line restarts, through the meshing of the teeth 5 and the drive gear 13, the roller 1 maintains a stable linear speed of 2.8 m / s driven by the drive shaft 12 (40mm in diameter). Compared with the traditional equipment, this greatly reduces downtime losses when changing rollers.

[0031] Example 2: Please refer to Figure 1 , Figure 2 , Figure 3 and Figure 4 A roller assembly with a quick-release structure is disclosed. Each roller includes a roller body 1 and a quick-release structure, wherein the quick-release structure adopts a modular design. The quick-release structure includes a first mounting base 3, a baffle 2, a slot 6, and a limiting groove 7. The first mounting base 3 is rotatably connected to one end of the roller body 1, and the other end of the roller body 1 is rotatably connected to the slot 6. The baffle 2 is fixedly installed at the connection between the first mounting base 3 and the roller body 1. The inner wall of the slot 6 has a vertically opened limiting groove 7. The quick-release structure enables the roller assembly to be quickly disassembled on the workbench 10.

[0032] The two ends of the roller body 1 pass through the inner walls of the baffle 2 and the slot 6 respectively. One end of the roller body 1 extends into the cavity formed by the baffle 2 and the first mounting base 3. The roller body 1 in the cavity is equipped with a first bearing 8. The other end of the roller body 1 extends into the slot 6. The roller body 1 in the slot 6 is equipped with a second bearing 9.

[0033] The roller assembly is mounted on the workbench 10. One end of the workbench 10 has a groove that matches the first mounting seat 3, and the other end of the workbench 10 is mounted on the second mounting seat 15. The second mounting seat 15 includes: a slider 16, a slide rail 17, a limiting strip 18, an electromagnetic fixing block 19, and a second motor 20. The slide rail 17 is fixedly mounted inside the second mounting seat 15. An electromagnetic fixing block 19 is fixedly mounted on one end of the slide rail 17. The slider 16 is movably mounted on the slide rail 17. The slider 16 matches the slot 6. A limiting strip 18 that matches the limiting slot 7 is mounted on the side of the slider 16. The second motor 20 is connected to the other end of the slide rail 17. The second motor 20 drives the slider 16 to slide on the slide rail 17 to fix the slot 6.

[0034] The workbench 10 is equipped with a first motor 11 on one side and a movable driven gear 14 on the other side. The output end of the first motor 11 is connected to a drive shaft 12. The other end of the drive shaft 12 is fixedly equipped with a driving gear 13. The driving gear 13 and the driven gear 14 mesh with the teeth 5 on the roller 4.

[0035] Furthermore, the textile printing and dyeing material conveying system was upgraded. The original conveying rollers in the wide-width fabric dyeing and finishing plant used flange-connected roller groups, which required disassembling 32 sets of bearing seat bolts every week for cleaning. After the upgrade, this quick-release structure was adopted. The roller body 1 is made of 304 stainless steel, and the first bearing 8 and the second bearing 9 are configured at both ends. The bearings are SKF 6208 deep groove ball bearings. A double-layer nitrile rubber sealing ring is set at the joint between the baffle 2 and the roller body 1.

[0036] During maintenance, technicians unlock the safety pin, and the slider 16 inside the second mounting base 15 automatically retracts 100 mm under the drive of the second motor 20. Operators can lift the roller body 1 without tools. The tolerance fit between the slot 6 and the slider 16 has been optimized: the inner diameter tolerance of the slot 6 is controlled at H7 grade, and the outer diameter of the slider 16 adopts g6 grade tolerance. The fit clearance of 0.02-0.05 mm ensures no shaking. When installing after cleaning, the roller body 1 falls under its own weight, and the 5-degree guide slope at the top of the limit bar 18 automatically corrects the position. The electromagnetic fixing block 19 completes the energization and locking within 0.5 seconds. The disassembly time of the entire roller assembly is greatly shortened. Moreover, because the baffle 2 effectively prevents dye from seeping into the bearing, the failure rate of the equipment is greatly reduced. The transmission system adopts a modular gear set. The driving gear 13 with 28 teeth and the driven gear 14 with 32 teeth achieve a speed ratio of 1:1.14 by different numbers of teeth to meet the conveying tension requirements of different fabrics.

[0037] Example 3: Please refer to Figure 1 , Figure 2 and Figure 4A roller assembly with a quick-release structure is disclosed. Each roller includes a roller body 1 and a quick-release structure, wherein the quick-release structure adopts a modular design. The quick-release structure includes a first mounting base 3, a baffle 2, a slot 6, and a limiting groove 7. The first mounting base 3 is rotatably connected to one end of the roller body 1, and the other end of the roller body 1 is rotatably connected to the slot 6. The baffle 2 is fixedly installed at the connection between the first mounting base 3 and the roller body 1. The inner wall of the slot 6 has a vertically opened limiting groove 7. The quick-release structure enables the roller assembly to be quickly disassembled on the workbench 10.

[0038] The roller assembly is mounted on the workbench 10. One end of the workbench 10 has a groove that matches the first mounting seat 3, and the other end of the workbench 10 is mounted on the second mounting seat 15. The second mounting seat 15 includes: a slider 16, a slide rail 17, a limiting strip 18, an electromagnetic fixing block 19, and a second motor 20. The slide rail 17 is fixedly mounted inside the second mounting seat 15. An electromagnetic fixing block 19 is fixedly mounted on one end of the slide rail 17. The slider 16 is movably mounted on the slide rail 17. The slider 16 matches the slot 6. A limiting strip 18 that matches the limiting slot 7 is mounted on the side of the slider 16. The second motor 20 is connected to the other end of the slide rail 17. The second motor 20 drives the slider 16 to slide on the slide rail 17 to fix the slot 6.

[0039] The workbench 10 is equipped with a first motor 11 on one side and a movable driven gear 14 on the other side. The output end of the first motor 11 is connected to a drive shaft 12. The other end of the drive shaft 12 is fixedly equipped with a driving gear 13. The driving gear 13 and the driven gear 14 mesh with the teeth 5 on the roller 4.

[0040] Furthermore, the plastic sheet calendering equipment has been upgraded. In the PVC sheet production line, the traditional equipment requires hoisting equipment to replace the roller sets. This utility model is equipped with 36 sets of quick-release rollers on a 10-meter-long workbench 10. It features an innovative dual-power drive mode: the main drive end has a first motor 11 with a power of 7.5 kW, which is connected to the drive gear 13 through the drive shaft 12; the auxiliary end is equipped with a servo-controlled driven gear 14, which can move horizontally by 300 mm to adapt to different roller pitches.

[0041] When it is necessary to replace the surface-scratched roller 1, the operator first unlocks the safety pin. The second motor 20 drives the slider 16 to smoothly exit at a speed of 15 mm / s. The surface of the roller 1 is hard chrome plated and has double positioning at both ends: the cylindrical pin of the first mounting seat 3 forms initial positioning with the groove of the workbed 10; the limiting groove 7 in the slot 6 forms final positioning with the limiting strip 18, with a repeatability accuracy of 0.03 mm. After the new roller is installed, the electromagnetic fixing block 19 is pressurized in three stages: 0%, 50%, and 100% of the rated magnetic force to avoid impact loads. Under the working condition of 150℃, the radial runout of the roller 1 is less than 0.05 mm, which is far lower than the standard of 0.2 mm of the traditional structure. The transmission system realizes torque transmission through the hardened HRC58-62 teeth 5 of the roller 4. The single roller can maintain good synchronization accuracy even when bearing a maximum pressure of 1.8 tons, reducing the fluctuation of product quality.

[0042] Working principle: The operator checks the matching degree between the end groove of the workbed 10 and the first mounting seat 3, starts the second motor 20 of the second mounting seat 15, drives the slider 16 to retreat to the end of the slide rail 17, embeds the first mounting seat 3 of the roller into the groove of the workbed 10, slowly lowers the roller body 1, aligns the slot 6 with the base of the slider 16, triggers the second motor 20 to rotate forward, drives the slider 16 to move forward along the slide rail 17, the limit strip 18 is precisely inserted into the limit groove 7 on the inner wall of the slot 6, the electromagnetic fixing block 19 is energized to generate magnetic attraction force, fixes the roller, adjusts the position of the driven gear 14 to ensure that the driving gear 13 and the driven gear 14 can mesh with the teeth 5 on the roller 4, starts the first motor 11, drives the driving gear 13 through the transmission shaft 12, and forms a chain transmission through torque transmission, so that the entire roller group can operate. Before disassembling the roller group, a safety operation must be performed, disconnect the power supply of the first motor 11, and manually reverse the driven gear 14 to release the tension of the transmission system.

[0043] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description.
