Description

Technical Field

[0001] This invention belongs to the field of steel coil coating technology, specifically relating to a vertical steel coil coating device. Background Technology

[0002] Horizontal coating machines are the mainstream equipment for vacuum coating. The vacuum chamber has a horizontal layout, and the workpiece is clamped horizontally and rotated / transported along the horizontal axis. Combined with processes such as magnetron sputtering and electron beam evaporation, the workpiece surface is formed through processes such as vacuuming, plasma cleaning, coating, and thickness control. The core consists of a horizontal vacuum chamber, a gas extraction system, a horizontal workpiece rack, a target / evaporation source, and various monitoring systems. Compared with vertical models, it is more convenient for loading and unloading, has better coating uniformity, is suitable for large-scale batch processing of large / long / tubular workpieces, and also has the characteristics of modularity and easy maintenance. It is widely used in the preparation of functional films and coatings for photovoltaic glass, LOW-E glass, electronic devices, optical components, etc.

[0003] In the field of traditional horizontal coating machine technology, horizontal coating machines, designed to meet the process requirements of large-scale continuous coating production, typically have an overall layout length of tens of meters. Due to this structural limitation, a significant distance exists between the winding and unwinding mechanisms used for material transport. In actual coating production, the material must be transported from the unwinding to the winding mechanism to complete the coating process. However, within the transport section between these two mechanisms, there is a loss section where the material cannot effectively participate in the coating operation. The length of this loss section is directly related to the material's specifications; the material's length determines the actual size of this ineffective loss section, directly impacting the overall waste during production. The longer the material, the more significant the ineffective loss, resulting in more pronounced material waste, significantly increasing raw material costs and reducing overall production efficiency. Summary of the Invention

[0004] The purpose of this invention is to provide a vertical steel coil coating device to solve the problems of large ineffective loss of coating material and serious waste of raw materials caused by the long winding and unwinding distance of traditional horizontal coating machines.

[0005] To achieve the above objectives, this invention provides a vertical steel coil coating device, including a base frame, and further comprising: a storage chamber, rotating tubes, a guiding mechanism, a guide frame, and a conveying mechanism. The storage chamber is fixedly connected to the top of the base frame, and the top of the storage chamber is connected to a coating chamber capable of coating steel strips. A storage opening is provided on one side of the storage chamber. Two rotating tubes are provided, each rotatably connected to the storage chamber. Each of the two rotating tubes is provided with multiple tensioning rods for tightening the steel coils via a support mechanism. The support mechanism is used to support the expansion or contraction of adjacent tensioning rods. The guiding mechanism is disposed in the storage chamber and the coating chamber, and is used to change the conveying direction of the steel strips. The guide frame is fixedly connected to one side of the base frame, and is located at the bottom of the storage opening. The conveying mechanism is disposed on the guide frame, and is used to support the steel coils entering and exiting the storage chamber.

[0006] To support the steel coil entering the storage chamber and to support its rotation during unwinding at one end, the support mechanism includes a carriage, support rods, push rods, and a drive assembly. The rotating tube has multiple grooves, and the carriage is slidably connected within these grooves. Multiple support rods are rotatably connected to the rotating tube. Multiple push rods are rotatably connected to the carriage. Each tensioning rod is rotatably connected to the other end of each adjacent support rod and push rod. The drive assembly is located inside the rotating tube and drives the carriage to move within it. The drive assembly includes a fixed plate, a drive screw, and a first motor. The fixed plate is fixedly connected to one end of the rotating tube, and one end of the drive screw is rotatably connected to the fixed plate. The carriage has a threaded hole, and the drive screw is threaded into this hole. The first motor is mounted on the other side of the fixed plate, and its output end is fixedly connected to the drive screw.

[0007] In order to guide the steel coil during the conveying and unfolding process and change the direction of one end of the steel coil, the guiding mechanism includes: guide rollers and heaters. Multiple guide rollers are provided, and multiple guide rollers are rotatably connected to the storage chamber and the coating chamber. Multiple heaters are provided, and multiple heaters are installed in the storage chamber and the coating chamber.

[0008] For conveying or storing steel coils indoors or outdoors, the conveying mechanism includes: a moving platform, rotating rods, guide rails, and a drive assembly. The moving platform is located at the top of the guide frame. There are two rotating rods, both rotatably connected to the bottom of the moving platform. Moving wheels are fixedly connected to both ends of the two rotating rods. There are two guide rails, both fixedly connected to the top of the guide frame. Moving wheels located on both sides of the moving platform contact the two guide rails respectively. The drive assembly is mounted on the moving platform and is used to drive the moving platform to move on the guide rails. The drive assembly includes: sprockets, a second motor, and a chain. There are two sprockets, one of which is fixedly connected to the rotating rod. The second motor is mounted at the top of the moving platform, and the other sprocket is fixedly connected to the output end of the second motor. The chain drive is connected between the two sprockets.

[0009] To control the opening and closing of the storage opening, a door panel is hinged to the storage opening. The other side of the door panel is sealed and closed by a locking mechanism. The locking mechanism includes an electric cylinder and a pressing block. The electric cylinder is installed on one side of the storage chamber, and the pressing block is fixedly connected to the output end of the electric cylinder.

[0010] The significant technical advantages of this invention are as follows: by vertically connecting the storage chamber and the coating chamber, the steel strip completes unwinding, coating, and winding within a vertical space, greatly shortening the travel distance of the steel strip in the non-coating area, thereby significantly reducing the length of the ineffective loss section and saving coating material. Simultaneously, the centralized arrangement of the unwinding and winding mechanisms reduces the equipment footprint and the number of operators required. Attached Figure Description

[0020] Example 1, please refer to Figures 1-8This invention illustrates a vertical steel coil coating apparatus according to an embodiment of the present invention, including a base frame 1, and further including: a storage chamber 2, a rotating tube 5, a guiding mechanism, a guide frame 7, and a conveying mechanism. The storage chamber 2 is fixedly connected to the top of the base frame 1, and the top of the storage chamber 2 is connected to a coating chamber 3 capable of coating steel strips. A storage opening 4 is provided on one side of the storage chamber 2. Two rotating tubes 5 are provided, and both rotating tubes 5 are rotatably connected to the storage chamber 2. Each of the two rotating tubes 5 is provided with multiple tensioning rods 6 for tightening the steel coils through a support mechanism. The support mechanism is used to support the expansion or contraction of adjacent tensioning rods 6. The guiding mechanism is set in the storage chamber 2 and the coating chamber 3 to change the conveying direction of the steel strip. The guide frame 7 is fixedly connected to one side of the base frame 1 and is located at the bottom of the storage opening 4. The conveying mechanism is set on the guide frame 7 to support the steel coils entering and exiting the storage chamber 2.

[0021] The vertical layout reduces the travel distance of the steel strip between the coating and non-coating areas from tens of meters in traditional horizontal equipment to just a few meters, significantly reducing the length of "ineffective sections." The arrangement of the guide rollers 15 ensures stable tension of the steel strip during turning, and the heater 16 enhances the surface activity of the material before coating, further strengthening the coating adhesion. The machine has a compact structure, making it suitable for factory layouts with limited space, and is especially suitable for continuous coating production of large-diameter steel coils, effectively improving material utilization and production efficiency.

[0022] The support mechanism includes: a carriage 8, support rods 10, push rods 11, and a drive assembly. Multiple grooves 9 are provided on the rotating tube 5, and the carriage 8 is slidably connected within these grooves. Multiple support rods 10 are provided, each rotatably connected to the rotating tube 5. Multiple push rods 11 are provided, each rotatably connected to the carriage 8. Each tension rod 6 is rotatably connected to the other end of each adjacent support rod 10 and push rod 11. The drive assembly is located inside the rotating tube 5 and is used to drive the carriage 8 to move within the rotating tube 5. The drive assembly includes: a fixed plate 12, a drive screw 13, and a first motor 14. The fixed plate 12 is fixedly connected to one end of the rotating tube 5, and one end of the drive screw 13 rotates. The slide 8 is connected to the fixed plate 12 and has a screw hole. The drive screw 13 is threaded into the screw hole. The first motor 14 is installed on the other side of the fixed plate 12 and the output end of the first motor 14 is fixedly connected to the drive screw 13. When it is necessary to support and fix the hollow position of the steel coil, the first motor 14 drives the drive screw 13 to rotate. When the drive screw 13 rotates, it drives the slide 8 to move in the rotating tube 5 and the slide groove 9. The movement of the slide 8 drives the push rod 11 to swing, so that an adjacent push rod 11 and a support rod 10 perform a scissor movement, thereby driving the tension rod 6 to lift up and fix the steel coil. This realizes the expansion and contraction of the tension rod 6 to adapt to steel coils with different inner diameters.

[0023] The guiding mechanism includes: guide rollers 15 and heaters 16. Multiple guide rollers 15 are provided, and multiple guide rollers 15 are rotatably connected in the storage chamber 2 and the coating chamber 3. Multiple heaters 16 are provided, and multiple heaters 16 are installed in the storage chamber 2 and the coating chamber 3 to guide the steel strip. The heaters 16 are used to preheat the steel strip to improve the coating adhesion.

[0024] The conveying mechanism includes: a movable table 17, rotating rods 18, guide rails 20, and a drive assembly. The movable table 17 is located at the top of the guide frame 7. Two rotating rods 18 are provided, each rotatably connected to the bottom end of the movable table 17. Two wheels 19 are fixedly connected to both ends of each rotating rod 18. Two guide rails 20 are provided, each fixedly connected to the top of the guide frame 7. The wheels 19 located on both sides of the movable table 17 contact the two guide rails 20 respectively. The drive assembly is mounted on the movable table 17 and is used to drive the movable table 17 to move on the guide rails 20. The drive assembly includes: sprockets 21, a second motor 22, and a chain 23. Two sprockets 21 are provided. One sprocket 21 is fixedly connected to the rotating rod 18. A second motor 22 is mounted on the top of the moving platform 17. Another sprocket 21 is fixedly connected to the output end of the second motor 22. A chain 23 is driven between the two sprockets 21. The second motor 22 drives the sprockets 21 to rotate, and the chain 23 drives the rotating rod 18 to rotate. When the rotating rod 18 rotates, it drives the moving wheel 19 to roll on the guide rail 20, thereby supporting the moving platform 17 to move on the guide frame 7, thus moving the moving platform 17 to the storage port 4. This is used to drive the moving platform 17 to move along the guide rail 20, realizing the automatic feeding and unloading of steel coils. A door panel 24 is hinged to the storage opening 4. The other side of the door panel 24 is sealed and closed by a locking mechanism. The locking mechanism includes an electric cylinder 25 and a pressing block 26. The electric cylinder 25 is installed on one side of the storage chamber 2. The pressing block 26 is fixedly connected to the output end of the electric cylinder 25. The electric cylinder 25 drives the pressing block 26 to press the door panel 24 to ensure that the storage chamber 2 is sealed.

[0025] Working principle, when steel coils need to be coated: Material loading stage: A trolley needs to be placed on the moving table 17 to hoist the steel coil onto the trolley. Then, the second motor 22 drives the sprocket 21 to rotate, and the chain 23 drives the two sprockets 21 to rotate, thereby driving the rotating rod 18 to rotate. When the rotating rod 18 rotates, it drives the moving wheel 19 to roll on the guide rail 20, thereby supporting the moving table 17 to move on the guide frame 7, thereby moving the moving table 17 to the storage port 4. Then the moving trolley enters the storage room. During this process, the hollow part of the steel coil is inserted into the adjacent tension rods 6. Tensioning and fixing stage: The first motor 14 drives the drive screw 13 to rotate. When the drive screw 13 rotates, it drives the slide 8 to move in the rotating tube 5 and the slide groove 9. The movement of the slide 8 drives the push rod 11 to swing, so that an adjacent push rod 11 and a support rod 10 perform a scissor movement, thereby driving the tension rod 6 to lift up, and then tightening the inner wall of the steel coil to fix the steel coil. Threading and Coating Stage: The rotating tube 5 rotates within the storage chamber 2, supporting the unfolding of the steel coil. The unfolded steel coil passes through multiple guide rollers 15, which change the direction of one end. After passing through the guide rollers 15, the coil is wound onto multiple tension rods 6. The rotation of two rotating rods 18 transports the steel coil, shortening the transport distance. The heater 16 enhances the coating effect of the steel coil. Coiling and unloading stage: After the steel coil is conveyed, the trolley is moved to the other end of the storage chamber 2, the tension rod 6 releases the support of the steel coil, thereby moving the coiled steel coil to the moving table 17, and the second motor 22 rotates in the opposite direction to unload the steel coil.

[0026] Example 2, please refer to Figures 9-10 To guide and correct the deviation of the steel coil during transport, a vertical steel coil coating device also includes a deviation correction mechanism. The deviation correction mechanism includes a stabilizing plate 27, a moving rod 28, a support rod 29, a sliding box 30, and a first electric cylinder 31. The stabilizing plate 27 is fixedly connected to the inner wall of the coating chamber. Two linkage rods 32 are rotatably connected to the stabilizing plate 27. The moving rod 28 is rotatably connected to the other end of the two linkage rods 32. The support rod 29 is fixedly connected to the bottom end of the moving rod 28. A moving frame 33 is slidably connected to the support rod 29. A deviation correction wheel 34 is rotatably connected to the moving frame 33. A guide groove is opened in the deviation correction wheel 34. The sliding box 30 is fixedly connected to the top end of the moving rod 28. A drive frame 35 is slidably connected inside the sliding box 30. The first electric cylinder 31 is installed on one side of the coating chamber. The output end of the first electric cylinder 31 passes through the coating chamber and is fixedly connected to the drive frame 35.

[0027] The working principle is as follows: when it is necessary to correct the deviation of the steel coil during conveying, both sides of the steel coil contact the guide grooves opened on the two correction wheels 34 respectively. At this time, the moving frame 33 slides adaptively on the support rod 29. When the steel coil deviates during conveying, the first electric cylinder 31 drives the drive frame 35 to move. When the drive frame 35 moves, it slides adaptively in the sliding box 30, thereby driving the sliding box 30 and the moving rod 28 to move. When the moving rod 28 moves, the two linkage rods 32 swing on the stabilizing rod, thereby pushing the steel coil to move, thus correcting the deviation of the steel coil and preventing the steel coil from deviating during conveying.
