Description

Technical Field

[0001] This invention relates to the field of aluminum strip coating technology, and more particularly to an aluminum strip coating production apparatus. Background Technology

[0002] The aluminum foil roll coating production equipment for food packaging is a key piece of equipment in the aluminum processing and food packaging fields. Its core function is to continuously and uniformly coat the surface of aluminum foil for food packaging. By coating the surface of the aluminum foil with functional food-grade safety and barrier properties such as anti-corrosion and decoration, the corrosion resistance, abrasion resistance, appearance and texture barrier properties, temperature resistance and food safety adaptability of the aluminum foil for food packaging are significantly improved. This makes the aluminum foil for food packaging widely adaptable to the application needs of various food packaging scenarios such as food preservation packaging, cooked food sealing packaging, and snack moisture-proof packaging. It is the core link to realize the added value of aluminum foil products for food packaging.

[0003] In existing technologies, the conventional process of aluminum foil roll coating production equipment for food packaging mainly includes basic units such as unwinding, guiding, coating, and curing. Conventional equipment typically uses a single unwinding mechanism to transport the aluminum strip, controls the strip's trajectory through fixed guide rollers, and relies on a simple mechanical correction structure to adjust strip deviation. The core design of this type of equipment focuses on the basic coating application function, lacking targeted optimization in terms of operational stability and precision control. It generally adopts an integral correction roller structure and relies heavily on manual observation or a single sensor for deviation detection.

[0004] Existing technologies have significant shortcomings:

[0005] 1. During the conveying process of aluminum strip, lateral deviation is easily caused by factors such as fluctuation of unwinding tension and wear of guide rollers. Conventional correction mechanisms have a slow response and low adjustment accuracy, resulting in uneven coating edges and uneven thickness, which affects product quality.

[0006] 2. The lack of precise trajectory positioning and real-time monitoring mechanisms makes it impossible to dynamically capture changes in the aluminum strip's running trajectory, making it difficult to adapt to the production needs of aluminum strips with different widths and thicknesses.

[0007] 3. Most of the correction mechanisms are rigid and lack a buffer compensation structure. When the aluminum strip is conveyed at high speed, instantaneous stress concentration is likely to occur, causing scratches or tensile deformation on the surface of the aluminum strip.

[0008] 4. The overall structure lacks flexibility, the adjustment range of the guiding and correction components is limited, and the adaptability is poor. It is difficult to meet the process requirements of food-grade high-precision coating production and cannot fully adapt to the strict standards of product consistency in the food packaging industry.

[0012] As a preferred technical solution of the present invention, a guide pressure roller is rotatably installed between each pair of inverted support shafts, and an adjustment motor is fixedly installed on one side of each inverted support shaft. One set of inverted support shafts is fixedly installed on the lower surface of the mounting top plate and located at the front end of the mounting column, while the other set of inverted support shafts is fixedly installed at the front end of the equipment support side column.

[0013] As a preferred technical solution of the present invention, the trajectory positioning mechanism further includes a sliding mounting seat that is slidably mounted on the upper end of the probe mounting guide rail, and a vision probe is fixedly mounted on one side of the sliding mounting seat.

[0014] As a preferred technical solution of the present invention, the conveying correction mechanism includes a correction execution platform fixedly installed at the rear end of two straight plates. A correction sensor is fixedly installed at the lower end of the front surface of the correction execution platform, and a correction execution cylinder is fixedly installed on the front surface of the correction execution platform on one side of the correction sensor.

[0015] As a preferred technical solution of the present invention, the output end of the correction execution cylinder is rotatably mounted with an adjustment bracket, the adjustment bracket has a symmetrical structure, and a movable groove is opened on one side of the outer surface of the adjustment bracket. The output end of the correction drive motor is rotatably mounted with a roller end drive shaft head, and an inner support cylinder of the roller body is sleeved on the outside of the roller end drive shaft head.

[0016] As a preferred technical solution of the present invention, a roller end bearing cover is fixedly installed on one side of the roller end drive shaft head, a return spring is sleeved on one side of the outer surface of the roller end bearing cover, a linkage ring is fixedly installed on the other side of the roller end drive shaft head, two sets of outer rotating seats arranged at equal angles are fixedly installed on the outer surfaces of the linkage ring and the roller end bearing cover, a linkage adjustment plate corresponding to the outer rotating seat is rotatably installed on the outer side of the roller end bearing cover, and several corresponding independent correction rollers are fixedly installed at the rear end of each linkage adjustment plate.

[0017] As a preferred technical solution of the present invention, two sets of inner rotating seats are fixedly installed on both sides of the inner surface of the independent correction roller. The inner rotating seats correspond to the outer rotating seats fixedly installed on the outer surface of the roller end bearing cover and the linkage ring. Each inner rotating seat and the outer rotating seat are connected by a pin, and an adjustment buffer mechanism is rotatably installed between the two pins.

[0019] Compared with the prior art, the present invention has the following beneficial effects:

[0020] 1. This invention employs a monitoring mechanism combining a correction sensor and a vision probe. The vision probe can move flexibly along the guide rail to capture the aluminum strip's running trajectory in real time, and works with the correction sensor to accurately identify the offset. Simultaneously, through the combined design of an independent correction roller and a linkage adjustment plate, combined with the coordinated drive of the correction drive motor and the execution cylinder, it achieves rapid and accurate correction of the aluminum strip's offset, solving the problem of uneven coating caused by the lag and insufficient accuracy of the correction in the prior art.

Through the cooperation of the slide bar, buffer spring and slider guide groove, it can buffer the instantaneous stress during the aluminum belt conveying process and avoid surface scratches or tensile deformation caused by rigid adjustment. In addition, the elastic compensation effect of the return spring effectively balances the conveying tension, greatly reduces the wear of aluminum belt during high-speed operation and improves the product qualification rate.

[0022] 3. The spacing of the guide rollers can be flexibly adjusted via the motor, and the sliding mounting base of the trajectory positioning mechanism can adapt to the monitoring needs of aluminum strips of different widths. The modular design of the independent correction rollers also facilitates configuration adjustments according to production scenarios. Compared to the fixed structural design of existing technologies, this device can adapt to the coil coating production of aluminum strips of various specifications, reducing equipment replacement costs and improving production efficiency.

[0034] The following description is intended to disclose the invention and enable those skilled in the art to implement it. The preferred embodiments described below are merely examples, and other obvious variations will occur to those skilled in the art.

[0035] like Figures 1-10 The aluminum strip coil coating production device shown includes a mounting top plate 1. Two inverted support shafts 6 are fixedly installed on the lower surface of the mounting top plate 1. Symmetrical mounting columns 2 are fixedly installed on one side of the lower surface of the mounting top plate 1. Side support platforms 3 are fixedly installed on the front surfaces of the two mounting columns 2. An aluminum strip coil unwinding mechanism is fixedly installed on the upper end of the side support platforms 3. Equipment support side columns 12 are fixedly installed on the lower surface of the mounting top plate 1 at the rear end of the mounting columns 2. Side support shafts 5 are fixedly installed on one side surface of the equipment support side columns 12. Symmetrically arranged straight plates 27 are fixedly installed on the rear surface of the side support shafts 5. Another set of side support shafts 5 is fixedly installed on the side surface of the two straight plates 27 away from the equipment support side columns 12. A correction drive motor 9 is fixedly installed on the outer surface of one straight plate 27. A conveying correction mechanism is fixedly installed at the output end of the correction drive motor 9. A probe mounting guide rail 13 is fixedly installed on the upper end of the straight plate 27. A trajectory positioning mechanism is fixedly installed on the upper end of the probe mounting guide rail 13.

[0036] The device uses the mounting plate 1 as its core load-bearing foundation, with its lower surface supported by symmetrically distributed mounting columns 2. The mounting columns 2 not only connect the mounting plate 1 to the side support platforms 3, but also, through their rigid structure, resist vibrations generated during equipment operation, preventing foundation sway from affecting the accuracy of aluminum strip conveying. Side support platforms 3 are fixedly mounted on the front surfaces of both mounting columns 2. These side support platforms 3 provide a dedicated mounting platform for the aluminum strip unwinding mechanism. Their flat upper surfaces ensure the horizontality of the strip support shaft 4, thereby guaranteeing the coaxiality of the aluminum strip coil 7 during unwinding and reducing the risk of misalignment during the initial conveying stage.

[0037] The aluminum strip unwinding mechanism, as the starting unit for aluminum strip conveying, consists of a strip roll support shaft 4, an unwinding drive motor 8, and an aluminum strip roll 7. The strip roll support shaft 4 is fixedly installed on the upper end of the side support platform 3 and is made of high-strength alloy material. It can accommodate aluminum strip rolls 7 of different weights. The aluminum strip roll 7, which is rotatably installed between the two strip roll support shafts 4, is provided with stable driving force by the unwinding drive motor 8. The unwinding drive motor 8 adopts a variable frequency speed regulation design, which can precisely adjust the unwinding speed according to the requirements of subsequent coating processes, ensuring that the aluminum strip conveying rate matches the rhythm of coating, curing and other processes, and avoiding uneven tension caused by speed fluctuations.

[0038] Two sets of inverted support shafts 6 are fixedly installed on the lower surface of the mounting plate 1. One set is located at the front end of the mounting column 2, and the other set is fixed at the front end of the equipment support side column 12. The two sets of inverted support shafts 6 form a front-to-back guiding structure, providing a continuous and stable conveying path for the aluminum strip. A guide roller 16, rotatably installed between every two inverted support shafts 6, has a wear-resistant rubber coating on its surface, which enhances the friction with the aluminum strip surface, preventing slippage during conveying and avoiding scratches on the aluminum strip surface. An adjusting motor 10, fixedly installed on one side of the inverted support shafts 6, can adjust the spacing of the inverted support shafts 6 in real time through a screw drive structure, thereby changing the clamping force of the guide roller 16 on the aluminum strip to adapt to the conveying needs of aluminum strips of different thicknesses. Simultaneously, stable pressure control reduces lateral deviation of the aluminum strip caused by uneven tension.

[0039] The lower surface of the mounting plate 1, located at the rear end of the mounting column 2, serves as the equipment support side column 12. This not only provides a mounting carrier for the side support shaft 5 but also ensures the verticality and stability of the subsequent alignment mechanism installation through its own vertical support structure. The side support shaft 5 is fixedly mounted on one side surface of the equipment support side column 12, and its rear end is fixed with a symmetrical straight plate 27, forming the mounting frame for the alignment mechanism. The straight plate 27 is made of thickened steel plate, capable of withstanding the torque and vibration generated by the alignment drive motor 9 during operation, ensuring the stability of the alignment action.

[0040] The trajectory positioning mechanism, serving as the monitoring unit for the correction action, is primarily composed of a probe mounting rail 13, a sliding mounting base 14, and a vision probe 15. The probe mounting rail 13 is fixedly mounted on the upper end of the straight plate 27, employing a high-precision linear guide design with a surface hardened to ensure smooth sliding and positioning accuracy of the sliding mounting base 14. The sliding mounting base 14 is connected to a drive motor via a built-in ball screw, allowing for flexible position adjustment along the probe mounting rail 13. This, in turn, drives the fixedly mounted vision probe 15 to precisely adjust its monitoring range, adapting to the trajectory monitoring needs of aluminum strips of varying widths. The vision probe 15 utilizes a high-definition industrial camera to capture the running trajectory of the aluminum strip's surface and edges in real time. Image recognition algorithms convert the trajectory data into electrical signals, transmitting them to the control system to provide precise positional references for the correction action.

[0041] The conveying and correction mechanism, as the core execution unit of the device, undertakes the crucial function of correcting aluminum strip misalignment. It is fixed to the rear ends of two straight plates 27, forming an independent and compact correction module. The correction execution platform 11 serves as the mounting carrier for the correction sensor 17 and the correction execution cylinder 18. Its flat front surface ensures the coaxiality and levelness of the two components, guaranteeing consistency between detection and execution actions. The correction sensor 17 is fixedly installed at the lower end of the front surface of the correction execution platform 11. Utilizing infrared ranging, it can accurately detect the offset of the aluminum strip edge from the preset trajectory, with a detection accuracy of ±0.01mm. Together with the vision probe 15, it forms a dual monitoring mechanism, avoiding potential misjudgments that may occur with a single monitoring method.

[0042] The adjusting bracket 19, which is rotatably mounted on the output end of the corrective actuator cylinder 18, has a symmetrical structure. A movable groove 20 on one side of its outer surface provides adjustment space for the roller end drive shaft head 21, ensuring the coordinated movement of all components during the correction process. The roller end drive shaft head 21, rotatably mounted on the output end of the correction drive motor 9, is fixed to the internal support cylinder 28 of the roller body via a spline connection. The internal support cylinder 28 adopts a hollow cylindrical structure, reducing its own weight while ensuring structural rigidity through high-strength alloy material, providing stable support for the subsequent independent correction roller 23.

[0043] A roller end bearing cap 24, fixedly installed on one side of the roller end drive shaft head 21, seals and secures the internal bearing, preventing dust, oil, and other impurities from entering the bearing and affecting rotational accuracy. A return spring 26, fitted onto one side of the outer surface of the roller end bearing cap 24, returns the relevant components to their initial position via elastic restoring force after the correction action is completed, preparing for the next correction action. Simultaneously, during the correction process, elastic deformation balances some instantaneous stress, reducing rigid impact. A linkage ring 30, fixedly installed on the other side of the roller end drive shaft head 21, and two sets of equally angled outer rotating seats 25 are fixedly installed on the outer surface of both the roller end bearing cap 24 and the outer rotating seats 25. These outer rotating seats 25 are rotatably connected to the linkage adjustment plate 22 via pins 31, ensuring that the linkage adjustment plate 22 can be flexibly adjusted in angle.

[0044] Several independent correction rollers 23 are fixedly installed at the rear end of each linkage adjustment plate 22. Adopting a modular design, their number can be flexibly increased or decreased according to the width of the aluminum strip. The surface of each independent correction roller 23 is also coated with a wear-resistant and anti-slip coating. When in contact with the aluminum strip, they can achieve trajectory correction through friction while reducing damage to the aluminum strip surface. Two sets of inner rotating seats 29 are fixedly installed on both sides of the inner surface of each independent correction roller 23. These seats are precisely connected to the outer rotating seat 25 via pins 31, ensuring that the independent correction roller 23 can rotate flexibly around the pins 31 to adapt to the angle adjustment requirements during the correction process.

[0045] The adjustable buffer mechanism, rotatably mounted between two pins 31, serves as a "flexible compensation unit" for the correction action, effectively alleviating the instantaneous stress between the aluminum strip and the correction roller during high-speed conveying. The slide bar 32 in the adjustable buffer mechanism is connected to the inner rotating seat 29 via a pin 31 on one side. Symmetrical limiting pins 35, fixed to the lower end of its outer surface, are slidably mounted within the slider guide groove 37 of the mounting base 33, forming a stable sliding guide structure to prevent deviation during slide bar 32 movement. A slot 36 on the inner side of the slide bar 32 provides installation space for the buffer spring 34. The buffer spring 34 is fixedly mounted on the outer surface of the mounting base 33 and located inside the slot 36. When the independent correction roller 23 is subjected to an instantaneous impact force from the aluminum strip, the slide bar 32 slides along the slider guide groove 37, compressing the buffer spring 34. The spring's elastic deformation absorbs the impact force, preventing stretching deformation or surface scratches on the aluminum strip caused by rigid adjustment, thus ensuring the quality of the aluminum strip product.

[0046] Working principle:

[0047] The aluminum strip coil 7 is mounted on the side support platform 3 via the coil support shaft 4. After the unwinding drive motor 8 starts, it drives the aluminum strip coil 7 to unwind at a uniform speed. The aluminum strip passes through the guide rollers 16 between the inverted support shafts 6 at the front end of the mounting column 2, and is then conveyed towards the equipment support side column 12 on the lower surface of the mounting top plate 1. After being guided by the side support shaft 5, it enters the correction operation area built by the straight plate 27. After the trajectory is corrected by the conveying correction mechanism, the aluminum strip is temporarily stored by the dedicated take-up roller. After take-up, the aluminum strip is accurately sent to the glue coating area for surface treatment. During this process, the adjusting motor 10 can adjust the spacing of the inverted support shafts 6 in real time according to the thickness of the aluminum strip, so that the guide rollers 16 form a suitable clamping force on the aluminum strip. The side support shaft 5 and the straight plate 27 form a stable conveying and correction support frame. With the overall bearing and positioning of the mounting top plate 1, the coaxiality and stability of the linkage of each component are ensured. This ensures smooth conveying and avoids deformation of the aluminum strip due to excessive pressure, laying a stable conveying foundation for the subsequent take-up and glue coating processes.

[0048] The trajectory positioning mechanism is activated synchronously. The sliding mounting base 14 moves flexibly along the probe mounting guide rail 13 fixed at the upper end of the straight plate 27, driving the vision probe 15 to adjust its monitoring position to adapt to the production needs of aluminum strips of different widths. The mounting top plate 1 provides rigid vertical support for the side support shaft 5 and the straight plate 27 through the equipment support side column 12, ensuring the installation level of the probe mounting guide rail 13 and keeping the monitoring trajectory of the vision probe 15 accurate. The vision probe 15 captures the running trajectory of the aluminum strip surface and edge in real time and transmits the image data to the control system. At the same time, the correction sensor 17 on the correction execution platform 11 accurately detects the lateral offset of the aluminum strip, forming a complementary verification with the data from the vision probe 15, ensuring the accuracy and comprehensiveness of the offset information collection, providing a reliable basis for subsequent correction actions, and preventing the offset aluminum strip from entering the receiving stage and the glue coating area, thus affecting the processing accuracy.

[0049] When the control system detects a deviation in the aluminum strip, it immediately triggers the coordinated operation of the correction drive motor 9 fixed on the outside of the straight plate 27 and the correction execution cylinder 18 on the correction execution platform 11. The side support shaft 5 provides double-sided fixed support for the straight plate 27, offsetting the torque generated by the operation of the correction drive motor 9 and ensuring the stability of the correction action. The mounting top plate 1 rigidly connects the side support shaft 5, the straight plate 27, and the overall device through the equipment support side column 12 to prevent component shaking during the correction process. The correction drive motor 9 drives the internal support cylinder 28 of the roller body to rotate through the roller end drive shaft head 21. At the same time, the correction execution cylinder 18 pushes the adjusting bracket 19 to finely adjust the angle along the movable groove 20. Through the linkage, the roller end drive shaft head 21 and the connected components are shifted as a whole. The linkage adjustment plate 22 on the outside of the roller end bearing cover 24 rotates synchronously under the action of driving force, thereby driving each set of independent correction rollers 23 to adjust the contact angle. By using the friction between the independent correction rollers 23 and the surface of the aluminum strip, the offset direction is corrected in the opposite direction to achieve rapid correction and ensure that the aluminum strip enters the receiving stage and the subsequent coating area with a standard trajectory.

[0050] During the correction and adjustment process, the adjustment and buffer mechanism plays a crucial role. The straight plate 27 provides a fixed installation base for the entire conveying and correction mechanism. Together with the lateral limit of the side support shaft 5, it ensures that the movement of the adjustment and buffer mechanism always remains within the preset trajectory. When the independent correction roller 23 is subjected to instantaneous stress from the aluminum strip, the inner rotating seat 29 drives the slide bar 32 to slide along the slider guide groove 37 on the mounting base 33 through the pin 31. The limit pin 35 ensures the stability of the slide bar 32's movement trajectory. The buffer spring 34 in the empty groove 36 absorbs the impact force through compression and rebound, avoiding scratches or tensile deformation on the aluminum strip surface caused by rigid adjustment, and preventing damage to the aluminum strip surface from affecting the surface treatment effect of the coating area. Meanwhile, the return spring 26 on the outside of the roller end bearing cover 24 continuously provides elastic compensation to balance the conveying tension of the aluminum strip. The linkage ring 30, through the cooperation of the outer rotating seat 25 and the linkage adjustment plate 22, ensures that the actions of each set of independent correction rollers 23 are synchronized, further improving the correction accuracy and keeping the aluminum strip flat and intact after receiving. The overall bearing characteristics of the mounting top plate 1 ensure that the force of all the above-mentioned buffering and tension adjustment actions is evenly transmitted, avoiding local stress concentration that could damage the components.

[0051] In the surface treatment stage of the coating area, the aluminum strip, which has been temporarily stored and whose trajectory and surface condition meet the standards, is smoothly fed into the coating area. The inverted support shafts 6 on the lower surface of the mounting plate 1 and the side support shafts 5 form a continuous guide and conveying path. The correction area where the straight plate 27 is located is precisely connected to the coating area. Relying on the precise trajectory control and tension balance of this device in the early stage, the aluminum strip can maintain a uniform and stable running state in the coating area. The coating equipment can achieve uniform and precise coating treatment on the surface of the aluminum strip, and complete the application of functional coating on the surface of the aluminum strip. The guide roller 16 continuously provides stable guidance for the conveying of the aluminum strip in the coating area, while the side support shaft 5 performs a final lateral limit on the aluminum strip at the front end of the coating area to prevent the aluminum strip from shifting or wrinkling during the coating process, and ensure the process quality of the surface treatment.

[0052] The vision probe 15 and the correction sensor 17 maintain real-time monitoring. If the aluminum strip offset exceeds the set threshold, the control system will repeat the above correction process to form a continuous closed-loop adjustment. For aluminum strips of different specifications, the monitoring range of the vision probe 15 can be adjusted by sliding the mounting base 14, and the spacing of the guide rollers 16 can be changed by adjusting the motor 10. The modular design of the independent correction roller 23 can be flexibly adjusted according to production needs. The modular installation structure of the mounting top plate 1 provides a spatial basis for the adaptation and adjustment of each component. The connection method between the side support shaft 5 and the straight plate 27 can also be finely adjusted according to the width of the aluminum strip to ensure that the device is compatible with the production of aluminum strips of various widths and thicknesses, and ensures the regularity of aluminum strip receiving, the uniformity of surface treatment in the coating area, and the overall product quality of the aluminum strip throughout the process.
