Description

Technical Field

[0001] This invention relates to the field of steel coil and sheet roll forming equipment, and more particularly to a heavy-duty uncoiler expansion and contraction roll forming equipment. Background Technology

[0002] Heavy-duty uncoiler roll forming equipment is widely used in the unwinding, slitting, and rewinding of materials such as metals, paper, and plastic films, especially in production environments that require high loads and high-speed operation. With the increasing demands of industrial production, traditional roll forming systems can no longer meet the requirements for high precision, high efficiency, and stability. In metal processing, paper manufacturing, and plastic film production, the main task of the uncoiler is to unwind the raw materials on the roll and feed them into the production line for further processing.

[0003] Existing technologies, such as the invention with publication number CN110479793B, disclose a complete set of automatic uncoiling and centering equipment. This patent includes an uncoiling machine, a trolley, a centering and heightening device, and a pressure roller device. The bottom surface of the uncoiling machine has two parallel slide rails, and the upper end of the uncoiling machine has a roll. The trolley includes a drive unit, a base, and a centering clamping device. The drive unit drives the base to slide back and forth on the slide rails. The base has a lifting hydraulic cylinder, the output end of which is connected to the centering clamping device. The centering and heightening device includes two columns, each with a sensor. The pressure roller device includes a pressure roller bracket, a pressure arm, and a pressure roller hydraulic cylinder. The pressure roller bracket stands on one side of the roll, and one end of the pressure arm is hinged to the pressure roller bracket. The other end of the pressure arm has a drive roller. One end of the pressure roller hydraulic cylinder is connected to the pressure roller bracket, and the other end is connected to the pressure arm. This invention can achieve automated winding and centering of the roll material, saving manpower, with a high degree of intelligence, and precise centering.

[0004] During the operation of heavy-duty uncoiler expansion and contraction roll equipment, water droplets may condense on the surface of the roll and the roll and the roll and become damp due to ambient humidity, day and night temperature differences, or condensation carried by the strip itself. This can lead to corrosion of the strip surface, a decline in product quality, and accelerated oxidation and rust of the core mechanical components of the expansion and contraction roll, shortening the equipment's lifespan. Furthermore, the slippery surface during high-speed uncoiling can cause tension fluctuations, affecting production stability and efficiency. Summary of the Invention

[0005] The purpose of this invention is to solve the problems existing in the technology of heavy-duty uncoiler expansion and contraction roll equipment. During operation, water droplets will condense on the surface of the roll and the roll and the roll and become damp due to ambient humidity, day and night temperature difference or condensation carried by the strip itself. This will lead to corrosion of the strip surface, deterioration of product quality, and the damp environment will accelerate the oxidation and rust of the core mechanical components of the expansion and contraction roll, shorten the equipment life, and cause tension fluctuations due to the wet surface during high-speed uncoiling, affecting production stability and efficiency.

[0008] Preferably, a baffle is fixedly connected to one side of the connecting plate. The cross-section of the baffle is arc-shaped, and the cross-sectional dimensions of the baffle are adapted to the cross-sectional dimensions of the wind frame.

[0009] The effect achieved by the above components is that the arc-shaped design of the baffle is adapted to the cross-section of the air frame, which can effectively block the loss of hot air, ensure that the hot air is concentrated on the surface of the drum, reduce energy loss, and improve drying efficiency and uniformity.

[0012] Preferably, a positioning plate is fixedly connected to the surface of the adjusting rail at the position corresponding to the rotating plate. The positioning plate has an "L" shaped cross-section, and its inner wall is engaged with the surface of the rotating plate.

[0013] The above components achieve the following effects: the "L"-shaped design of the positioning plate can engage the rotating plate, providing additional fixing points to prevent the rotating plate from rotating or vibrating accidentally during equipment operation, thereby enhancing the overall stability of the drying device and ensuring that the air frame is always in the optimal working position.

[0014] Preferably, a guide ring is fixedly connected to the inner wall of the docking cover. The cross-section of the guide ring is arc-shaped, and the cross-section of the end of the guide ring near the connecting pipe is constricted.

[0015] The effects achieved by the above components are as follows: the arc-shaped and constricted design of the guide ring can optimize the airflow path, reduce the turbulence and loss of hot air in the docking hood, guide the airflow into the connecting pipe efficiently, improve the hot air delivery efficiency, and thus enhance the drying effect.

[0016] Preferably, a positioning device is provided on the side wall surface of the motor drive seat corresponding to the position of the drying device. The positioning device includes a slide rail, one side of which is fixedly connected to the surface of the motor drive seat. A side plate is slidably connected to the inner wall of the slide rail.

Several locking blocks are fixedly connected to the lower surface of the pressing plate. The locking blocks have a pointed conical cross-section. A rack is fixedly connected to the upper surface of the adjusting rail. The tooth surface of the rack engages with the surface of the locking blocks.

[0017] The effects achieved by the above components are as follows: the positioning device makes the position of the adjusting block adjustable through the sliding connection of the slide rail and the side plate; the adjusting rod and the pressing plate control the engagement of the locking block with the rack, which can quickly lock the position of the adjusting block, prevent the air frame from moving during the drying process, and ensure accurate drying position; the pointed conical design of the locking block enhances the biting force with the rack and improves the positioning reliability.

[0018] Preferably, the arc surface of the adjusting rod is fitted with a first spring, and the two ends of the first spring are fixedly connected to the extrusion plate and the side plate, respectively.

[0019] The effect achieved by the above components is that the first spring provides elastic force, which causes the pressing plate to automatically reset after the adjustment rod is operated, simplifying the adjustment process of the positioning device and improving the convenience and efficiency of operation.

[0020] Preferably, both sides of the upper surface of the side plate have sliding limit rods that slide through them, and the bottom end of the limit rods is fixedly connected to the surface of the extrusion plate.

[0021] The aforementioned components achieve the following effects: the limiting rod is fixedly connected to the extrusion plate to prevent the extrusion plate from rotating or shifting during movement, ensuring that the locking block and the rack are always accurately engaged, thereby improving the stability and accuracy of the positioning device.

[0022] Preferably, a maintenance device is provided on the upper sidewall surface of the air frame. The maintenance device includes an adjusting plate, one side of which is fixedly connected to the upper sidewall surface of the air frame. A through-tube slides through the inner wall of the adjusting plate. A lubricating oil pipe is fixedly connected to the upper end of the through-tube. An application block, which is a sponge block, is fixedly connected to the bottom end of the through-tube. A closed ring is fixedly connected to the arc surface of the inner wall of the through-tube. A closing post slides through the inner wall of the closed ring. Both sides of the arc surface of the closing post are open. The closed column is provided with an inlay hole. A sealing ring is fixedly connected to the bottom surface of the closed column. Movable grooves are provided on both sides of the inner wall of the closed column.

The two ends of the second spring are fixedly connected to the fixing ring and the adjusting plate, respectively.

[0023] The effects achieved by the above components are as follows: the maintenance device allows the coating block to contact the surface of the roll through the sliding connection of the adjusting plate and the through pipe; the lubricating oil pipe delivers lubricating oil to the coating block to achieve automatic lubrication of the roll; the closing ring and closing column control the flow of lubricating oil, and the adsorption effect between the magnetic block and the magnetic ring ensures the seal and prevents leakage; the second spring provides pressure to make the coating block stick tightly to the roll, apply lubricating oil evenly, reduce wear, and extend the service life of the equipment.

[0024] Preferably, a top block is fixedly connected to the bottom of the inner wall of the closed column, and the cross-section of the top block is conical.

[0025] The effect achieved by the above components is that the pointed cone design of the top block can pierce the blockage in the lubricating oil pipe or help the lubricating oil flow, ensuring smooth output of lubricating oil, preventing the maintenance device from failing due to blockage, and improving lubrication reliability.

[0026] Compared with the prior art, the advantages and positive effects of the present invention are as follows:

[0027] 1. In this invention, by setting up a drying device, and utilizing a sliding adjustable block and a rotatable rotating plate, the position and angle of the air frame are flexibly and precisely adjusted, making it adaptable to different specifications of rollers. The reset function of the coil spring ensures the convenience and stability of the adjustment. Hot air is efficiently introduced into the semi-circular air frame through the drying fan, conical docking cover, and connecting pipe, and is evenly sprayed onto the roller and roller surface by multiple nozzles, forming a directional and concentrated drying area. This allows for both lubrication and drying protection of the roller surface, and further provides anti-corrosion maintenance for the roller's arc surface.

[0028] 2. In this invention, a positioning device is used to achieve smooth movement of the entire drying device by utilizing the sliding cooperation between the slide rail and the side plate. A spring-driven adjusting rod and a pressing plate with a pointed conical locking block form a reliable ratchet locking mechanism with the rack and pinion. This device is simple to operate, enabling rapid locking and releasing of the adjusting block on the adjusting rail, effectively preventing accidental displacement of the drying device during operation under vibration conditions, and ensuring continuous stability and positional accuracy during the drying process.

[0029] 3. In this invention, a maintenance device integrates the lubrication function onto the air frame. A spring-loaded through-tube ensures the sponge applicator remains in contact with the drum surface. A magnetically adsorbed closed column and magnetic ring control the flow of lubricating oil, achieving automatic and uniform lubrication of the drum during equipment operation. The pointed cone design of the top block effectively prevents potential oil passage blockage. This device performs lubrication maintenance simultaneously with unwinding, reducing downtime, lowering the cost and safety risks of manual lubrication, and significantly extending the service life of core components such as the drum.

[0046] like Figure 8 and Figure 9 As shown, the maintenance device 7 includes an adjusting plate 706. One side of the adjusting plate 706 is fixedly connected to the upper side wall surface of the air frame 512. A through pipe 702 slides through the inner wall of the adjusting plate 706.

The inner wall of column 708 is provided with movable grooves 713 on both sides. A magnetic block 712 is slidably connected to the inner wall of the movable groove 713.

A top block 709 is fixedly connected to the bottom end of the inner wall of the closed column 708. The cross-section of the top block 709 is conical.

[0047] The overall working principle is as follows: during the long-term operation of the core pressure roller and unwinding roller driven by the motor drive seat 2 and the roller shaft 3, the automatic lubrication device integrated on the air frame 512 controls the opening and closing of the lubricating oil circuit through the magnetic control principle, and the lubricating oil is evenly applied to the surface of the roll by the sponge applicator 703 to achieve online automatic lubrication, reduce wear, and extend the service life of the equipment. At the same time, the hot air generated by the drying fan 514 is transported through the pipeline to the semi-circular air frame 512, which can flexibly adjust the position and angle, and finally sprayed evenly from multiple nozzles 513 to dry the lubricating oil applied to the arc surface of the roller shaft 3, and further perform anti-corrosion protection. In this process, the drying fan 514 is first started under the command of the controller 4 as a hot air source, and the generated hot air first enters the docking cover 515. The guide ring 516 inside the docking cover 515, with its unique constricted design, effectively gathers airflow, reduces turbulence and pressure loss, and allows hot air to enter the connecting pipe 517 more smoothly and efficiently. The hot air is then transported through the connecting pipe 517 to the semi-circular cross-section of the air frame 512, and finally ejected from multiple nozzles 513 evenly distributed on the inner wall of the air frame 512. This semi-circular design, combined with multiple nozzles 513, forms a wraparound, uniform drying area on the surface of the roll. The entire drying device 5 can move horizontally as a whole to accommodate rolls of different diameters or widths via the sliding connection between the adjusting block 502 and the adjusting rail 501. Fine angle adjustments are made via the rotating component 518. When operating the turntable 5186, the sliding groove 5187 on its surface drives the sliding rod 5184 to move, thereby causing the rotating plate 503 to rotate around its connection point with the fixed frame 504. The coil spring 505 always provides a restoring torque, increasing the stability of the system. Once the angle is adjusted to the correct position, tightening the auxiliary shaft 5185 will lock the slide bar 5184 and fix the angle. Furthermore, the positioning plate 5182 can serve as a fixing point for the rotating plate 503, providing additional stability. The air frame 512 is slidably connected to the connecting groove 508 on the connecting plate 507 via the connecting post 509 and locked with the connecting shaft 510, enabling quick installation and disassembly of the air frame 512 for easy maintenance. Through the above adjustments, it is ensured that the hot air ejected from the nozzle 513 always acts precisely and concentratedly on the key surfaces of the roller 3 and the drum, effectively improving drying efficiency and quality.

[0048] The positioning device 6 ensures that the adjusted drying device 5 will not shift under equipment vibration. During this process, the side plate 62 is connected to the motor drive seat 2 via the slide rail 61, and its bottom end is fixed to the adjusting block 502 of the drying device 5. Therefore, the movement of the drying device 5 directly drives the side plate 62 to move together. When the position needs to be adjusted, press down the adjusting rod 65 to compress the first spring 67, which drives the pressing plate 64 and the pointed cone-shaped locking block 68 at its bottom to move down, so that the locking block 68 disengages from the tooth surface of the rack 63. At this time, the side plate 62 and the adjusting block 502 can slide freely. When the position is determined, release the adjusting rod 65, and the restoring force of the first spring 67 will push the pressing plate 64 and the locking block 68 upward, so that the locking block 68 is firmly locked into the tooth groove of the rack 63. Since the locking block 68 is cone-shaped, it forms a self-locking effect with the rack 63, generating huge friction force, which effectively prevents accidental sliding in any direction. The limiting rod 66 passes through the side plate 62 and is fixed to the extrusion plate 64, ensuring that the extrusion plate 64 will not rotate during the up and down movement, maintaining the accuracy of the engagement between the locking block 68 and the rack 63, thus providing an absolutely stable working position for the drying device 5 in the event of strong equipment vibration.

[0049] The lubricating oil pipe 701 introduces lubricating oil into the through pipe 702. Under the pressure of the second spring 705 and guided by the adjusting plate 706, the entire through pipe 702 ensures that the coating block 703 at its bottom is always in close contact with the surface of the roll with slight pressure. In the non-lubricated or standby state, the magnetic ring 711 and the magnetic block 712 inside the closing column 708 attract each other. At this time, the top of the closing column 708 blocks the oil passage at the closing ring 707, and the sealing ring 714 at the bottom also ensures the seal at the bottom, preventing lubricating oil from flowing out. When lubrication is required, the magnetic ring 711 is manually slid. Since the magnetic ring 711 and the magnetic block 712 are in an attracted and fixed state, the magnetic ring 711 can drive the magnetic blocks 712 on both sides of the closing column 708 to slide synchronously, thereby moving the closing column 708 downward. When the inlay hole 710 on the closing column 708 moves to the oil passage of the through pipe 702, the lubricating oil flows down through the inlay hole 710, wets the coating block 703, and then coats the surface of the drum. The top block 709 at the bottom of the closing column 708 is cone-shaped. When it moves up and down, it can pierce the gel or blockage that may form in the oil passage, keep the oil passage unobstructed, realize the on-demand, controllable and automated lubrication process, ensure that the surface of the drum is uniformly lubricated, reduce wear, extend the equipment life, and avoid the waste and pollution of lubricating oil.
