Description

Technical Field

[0001] This utility model belongs to the field of metal packaging container color printing technology, specifically relating to a metal color printing anti-scalding bracket structure. Background Technology

[0002] In the color printing process of metal packaging containers, drying the containers is a crucial step. Traditional drying and conveying methods often use simple supports or direct contact conveying, which present numerous drawbacks when facing high-temperature environments. On the one hand, direct contact conveying can easily cause burns to operators, posing a high safety risk, and the high temperature may damage the surface of the metal packaging containers, affecting the color printing quality. On the other hand, simple supports are difficult to operate stably in high-temperature environments, and are prone to deformation and damage, causing containers to shift or tip over during conveying, which not only reduces production efficiency but also increases the defect rate.

[0003] Furthermore, ensuring uniform container spacing, stable transport, and precise chain tension control during the conveying of metal packaging containers in the drying chamber are crucial for guaranteeing product quality and production efficiency. However, existing technologies have significant shortcomings in these areas. Traditional limiting structures cannot effectively cope with the complex temperature field changes within the drying chamber, easily leading to limiting failure due to thermal expansion and contraction, resulting in uncontrolled container spacing. Simultaneously, conventional chain tension adjustment methods are mostly manual, which is not only cumbersome but also difficult to dynamically adjust in real-time based on the chain's operating status, failing to meet the requirements of modern, efficient, and stable production. Utility Model Content

[0004] The purpose of this utility model is to provide a metal color printing anti-scalding bracket structure to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a metal color-printed anti-scalding bracket structure, comprising:

[0006] The drying chamber has a chain drive mechanism at its bottom, which drives the anti-scalding iron frame to move linearly within the drying chamber. The inner and outer chain plates of the chain drive mechanism are evenly provided with iron frame fixing seats for detaching and fixing to the bottom of the anti-scalding iron frame. The anti-scalding iron frame is vertically installed on the upper end of the iron frame fixing seat for anti-scalding conveying of metal packaging containers within the drying chamber.

[0007] The drying chamber is equipped with a limiting track at the top of its interior to limit the movement of the anti-scalding iron frame within the drying chamber and maintain it in a vertical state with equal spacing. The chain drive mechanism is slidably disposed on tension adjustment blocks on both sides of the bottom of the drying chamber exterior. The inner side of the tension adjustment block is rotatably connected to the drive shaft through bearing components, and a tension cylinder with a tension monitoring component is provided on one side of the tension adjustment block for adjusting the tension of the drive chain.

[0008] Preferably, a middle main shaft and a rear main shaft are sequentially provided on the rear side of the transmission main shaft, both of which are rotatably installed on the bottom inner side of the drying chamber body; transmission sprockets are symmetrically arranged at both ends of the transmission main shaft, the middle main shaft and the rear main shaft, and a chain body is wound around the transmission sprockets to drive the anti-scalding iron frame to transport the metal packaging containers in the drying chamber in an anti-scalding manner.

[0009] Preferably, the flower iron frame fixing base has an inverted U-shaped structure and is fixed to the inner and outer chain plates of the chain body by pins; the anti-scalding flower iron frame is vertically fixed to the upper end of the flower iron frame fixing base by bolts.

[0010] Preferably, tension grooves are provided at the bottom of both sides of the main body of the drying chamber, the tension adjusting block slides in the tension grooves, and the tensioning cylinder is located on the rear side of the tension grooves.

[0011] Preferably, the tension groove is a frame-shaped structure with an opening on one side, and a limiting groove is provided at the bottom of its interior; a limiting slider is slidably connected inside the limiting groove, and the limiting slider is fixed to the lower end of the tension adjusting block.

[0012] Preferably, both ends of the transmission main shaft pass through the strip grooves opened on both sides of the drying chamber body, extend into the tension sliding groove, and are rotatably connected to the inside of the tension adjusting block; one end of the transmission main shaft passes through to the outside of the tension adjusting block and is connected to the motor for transmission, and the motor is installed on the outer surface of the tension adjusting block at the bottom of one side of the drying chamber body.

[0013] Preferably, the inner sidewall of the anti-scalding iron frame is uniformly provided with anti-scalding wheels, and the outer two sides are uniformly provided with auxiliary supports in a U-shape. The inner side of the auxiliary support is also provided with anti-scalding wheels. The upper surface of the anti-scalding iron frame is provided with U-shaped limiting frames on both sides for sliding on the limiting track. The limiting track is symmetrically fixed to the lower end of the top plate inside the drying chamber.

[0014] Preferably, a pressure sensor is installed on the air pipe connected to the tensioning cylinder to monitor changes in cylinder thrust or hydraulic system pressure, so as to indirectly reflect and adjust the tension of the chain body.

[0015] Compared with the prior art, the technical effects and advantages of this utility model are as follows:

[0016] This utility model effectively isolates the direct transmission of high temperature to metal packaging containers by designing an anti-scalding iron frame and matching it with anti-scalding wheels, thus solving the problem of container surface burns caused by direct contact in traditional conveying methods; at the same time, the anti-scalding wheels on the auxiliary support further enhance the stable support and anti-scalding protection of the container, thereby improving the surface quality of color-printed products.

[0017] This utility model achieves precise positioning and movement of the anti-scalding iron frame within the drying chamber by cooperating with the limiting track strip at the top of the main body of the drying chamber and the U-shaped limiting frame at the top of the anti-scalding iron frame. This ensures that the metal packaging containers always maintain an equally spaced vertical state during transportation, effectively solving the problem of limiting failure and container transportation deviation caused by temperature changes in traditional limiting structures, and improving transportation stability and printing accuracy.

[0018] This invention, by incorporating a tension cylinder with a pressure sensor and a tension adjusting block, combined with the guiding function of tension and limit grooves, can monitor and automatically adjust the tension of the chain body in real time, replacing the traditional manual adjustment method. This ensures that the chain maintains a stable transmission state in high-temperature environments, reduces downtime maintenance caused by abnormal chain tension, and improves production efficiency and equipment operation stability.

For example, "connection" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium; it can be a connection within two components. For those skilled in the art, the specific meaning of the above terms in this utility model can be understood according to the specific circumstances.

[0026] Please see Figure 1-4 This utility model provides a technical solution: a metal color-printed anti-scalding bracket structure, comprising:

[0027] The drying chamber body 1 serves as a closed space for drying metal packaging containers after color printing. Its bottom interior is equipped with a chain drive mechanism 2, which continuously drives the anti-scalding iron frame 8 to move linearly along a preset path within the drying chamber. The chain drive mechanism 2 has iron frame fixing seats 3 evenly arranged on its inner and outer chain plates. These fixing seats are detachable, allowing for quick assembly and disassembly from the bottom of the anti-scalding iron frame 8, facilitating future maintenance and replacement. The anti-scalding iron frame 8 is vertically installed on the upper end of the fixing seat 3. Its main body is made of high-temperature resistant material, providing support and anti-scalding transport for the metal packaging containers within the drying chamber, preventing direct contact between the containers and high-temperature components.

[0028] The drying chamber body 1 has symmetrically arranged limiting rails 4 at its top interior. These rails cooperate with the upper structure of the anti-scalding iron frame 8 to precisely limit the movement of the anti-scalding iron frame 8 along the rails within the drying chamber, ensuring that it remains vertically aligned with equal spacing and guaranteeing conveying stability. The chain drive mechanism 2 is slidably arranged on tension adjustment blocks 5 on both sides of the bottom exterior of the drying chamber body 1. The inner side of the tension adjustment block 5 is rotatably connected to the main drive shaft 6 via bearing components. The bearing components reduce the frictional resistance of the main drive shaft 6 during rotation, improving transmission efficiency. Furthermore, a tension cylinder 7 with tension monitoring components is provided on one side of the tension adjustment block 5. The tension cylinder 7 is a standard cylinder of model SC63×200-S with a cylinder diameter of 63mm and a stroke of 200mm. It can adjust the tension of the drive chain in real time through telescopic movements, ensuring the stability of the chain drive.

[0029] The transmission main shaft 6 is followed by a middle main shaft 9 and a rear main shaft 10. The three are distributed in parallel and are rotatably mounted on the bottom of the drying chamber body 1 through a bearing structure, forming a multi-point support transmission system. Transmission sprockets 11 are symmetrically arranged at both ends of the transmission main shaft 6, the middle main shaft 9, and the rear main shaft 10. The tooth profile of each transmission sprocket 11 is adapted to the chain body 12, and the chain body 12 is wound around each transmission sprocket 11. Through the meshing transmission between the sprocket and the chain, the anti-scalding iron frame 8 is driven to continuously transport the metal packaging containers in the drying chamber in an anti-scalding manner.

[0030] The flower iron frame fixing base 3 has an inverted U-shaped structure, which can be adapted to the shape of the inner and outer chain plates of the chain, so that the flower iron frame fixing base 3 is firmly fixed to the inner and outer chain plates of the chain body 12 by pins, ensuring the connection strength; the anti-scalding flower iron frame 8 is vertically fixed to the upper end of the flower iron frame fixing base 3 by bolts. The bolt connection method makes it easy to adjust the installation position of the anti-scalding flower iron frame according to the different specifications of containers.

[0031] Tension grooves 13 are provided at the bottom of both sides of the main body 1 of the drying chamber. The grooves provide sliding guides for the tension adjusting block 5. The tension adjusting block 5 can slide horizontally in the tension groove 13 to achieve position adjustment. The tension cylinder 7 is located on the rear side of the tension groove 13. Its cylinder body is fixed at the corresponding position of the main body of the drying chamber. The piston rod is connected to the tension adjusting block 5 to provide driving force for the adjusting block.

[0032] The tension slide 13 is a frame structure with an opening on one side. The opening design facilitates the installation and maintenance of the tension adjusting block 5. The tension slide 13 has a limiting slide 14 at the bottom inside. The cross-sectional shape of the limiting slide 14 matches that of the limiting slider 15. The limiting slider 15, which is fixed to the lower surface of the tension adjusting block 5, slides inside the limiting slide 14. The two work together to prevent the tension adjusting block 5 from shifting or shaking during the sliding process, thus ensuring the adjustment accuracy.

[0033] The two ends of the drive shaft 6 pass through the strip grooves opened on both sides of the drying chamber body 1. These strip grooves provide space for adjusting the position of the drive shaft 6. The two ends of the shaft extend into the tension slide groove 13 and are rotatably connected to the inner side of the tension adjusting block 5, so that the position change of the adjusting block can synchronously drive the shaft to move. One end of the drive shaft 6 passes through to the outside of the tension adjusting block 5 and is connected to the motor 16. The motor 16 is a YVF2-100L2-4 variable frequency speed control motor with a power of 3kW and a rated speed of 1430r / min. It serves as a power source to provide rotational power for the drive shaft 6. The motor 16 is installed on the outer surface of the tension adjusting block 5 at the bottom of one side of the drying chamber body 1, which saves installation space and facilitates the maintenance of the motor 16.

[0034] The inner wall of the anti-scalding iron frame 8 is evenly provided with anti-scalding wheels 17. These wheels are made of high-temperature resistant and wear-resistant materials and can rotate with the movement of the container to reduce friction with the container surface. The outer two sides are evenly provided with U-shaped auxiliary supports 18. The auxiliary supports 18 provide lateral restraint for the container. The anti-scalding wheels 17 are also rotatably provided on one side of the auxiliary supports 18 to further enhance the anti-scalding effect and support stability. The upper surface of the anti-scalding iron frame 8 is provided with U-shaped limiting frames 19 on both sides. These frames are fitted with limiting rails 4 and are used to smoothly limit the sliding on the limiting rails 4. The limiting rails 4 are symmetrically fixed to the lower surface of the top plate at the top of the main body of the drying room 1. The top plate provides a stable installation base for the rails.

[0035] A pressure sensor 20 is installed on the air pipe connected to the tension cylinder 7. The pressure sensor 20 is an MPM480 diffused silicon pressure transmitter with a measurement range of 0-1MPa and an accuracy of 0.2%FS. It can monitor the air pressure changes in the air pipe in real time, thereby reflecting the cylinder thrust or hydraulic system pressure changes, and thus indirectly obtaining the tension force data of the chain body 12. The motor 16, the tension cylinder 7 and the pressure sensor 20 are linked and controlled by a PLC control system (using Siemens S7-1200 series PLC). When the pressure sensor 20 detects an abnormal tension force, the PLC sends a command to control the tension cylinder to extend and retract to adjust the position of the tension adjusting block 5. At the same time, the transmission speed can be adjusted by the frequency converter motor to ensure that the chain is always in the best tension state and transmission efficiency.

[0036] Specifically, during use, the conveying drive and transmission are as follows: the motor 16 drives the transmission main shaft 6 to rotate, and the transmission sprockets 11 at both ends of the transmission main shaft 6, the middle main shaft 9, and the rear main shaft 10 drive the chain body 12 to rotate. The flower iron frame fixing seat 3 (inverted U-shaped structure, fixed to the inner and outer chain plates) on the chain body 12 moves accordingly, thereby driving the anti-scalding flower iron frame 8, which is vertically fixed on it, to move linearly in the drying chamber body 1, so as to realize the anti-scalding conveying of metal packaging containers.

[0037] Stable positioning of anti-scalding iron frame 8: Anti-scalding iron frame 8 is equipped with anti-scalding wheels 17 inside the inner side and the auxiliary brackets 18 on both sides, which can reduce friction damage when in contact with metal packaging containers, and at the same time avoid scalding problems caused by direct contact with high temperature.

[0038] The U-shaped limiting frame 19 at the top of the anti-scalding iron frame 8 slides on the limiting track 4 at the top of the drying room. Combined with the orderly nature of the chain drive, it ensures that the frame remains vertically aligned with equal spacing during movement, preventing tilting.

[0039] Chain tension adjustment and monitoring: The tension of the chain body 12 is adjusted by the tension cylinder 7: The tension adjusting block 5 slides in the tension grooves 13 on both sides of the drying chamber (the lower limit slider 15 is guided along the limit groove 14), which drives the transmission main shaft 6 to move, thereby realizing the adjustment of chain tension.

[0040] The pressure sensor 20 on the air pipe of the tension cylinder 7 monitors the change in thrust, indirectly reflecting the chain tension, which facilitates precise control of the tension and avoids the chain being too loose or too tight, thus affecting the stability of the conveyor.

[0041] Overall coordinated operation: The metal packaging container is placed between the anti-scalding iron frame 8 and the anti-scalding wheels 17 of the auxiliary support 18, and passes through the drying chamber body 1 at a uniform speed with the chain transmission mechanism 2; during the process, the cooperation between the limiting track bar 4 and the anti-scalding iron frame 8 ensures the stability of the movement trajectory, and the tension adjustment system maintains the chain tension in real time, so as to achieve the anti-scalding and orderly transportation of the metal packaging container in the drying chamber, and meet the drying and anti-scalding requirements after color printing.

[0042] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
