Description

Technical Field

[0001] This utility model relates to the field of corrugated paper production technology, specifically to a peripheral heating corrugated roll preheating device. Background Technology

[0002] Corrugated rolls are a key component in carton manufacturing, responsible for pressing cardboard into a corrugated shape. The heating performance of the corrugated rolls directly affects the quality and output of the cartons. Traditional corrugated roll heating methods mainly involve heating the roll body or cylinder. To overcome the limitations of traditional heating methods, peripheral heating corrugated roll preheating devices have emerged. This technology achieves a more uniform and efficient heating effect by heating the corrugated roll around its periphery.

[0003] While peripheral heating can provide a uniform heating effect, the heating rate is relatively slow because heat needs to be transferred gradually from the outside of the roller to the inside. This may affect the overall efficiency of the production line, especially when it is necessary to quickly switch between different specifications or models of corrugated rollers. Utility Model Content

[0004] The purpose of this invention is to provide a peripheral heating corrugated roll preheating device. By cooperating with the winding wheel and the resistance heating plate, and indirectly controlling the winding and unwinding of the resistance heating plate through the motor-driven rotating column, the relative position of the resistance heating plate and the corrugated roll can be flexibly adjusted. The resistance heating plate unfolds and is close to the corrugated roll, efficiently heating the corrugated roll, increasing the preheating speed, reducing waiting time, and thus improving production efficiency. During non-preheating periods or equipment maintenance, the resistance heating plate can be retracted to avoid potential damage from prolonged exposure or inconvenience to the surrounding environment, extending the service life of the resistance heating plate. At the same time, it also saves space in the equipment, making the overall layout of the equipment more compact and reasonable.

[0005] To achieve the above objectives, a peripheral heating corrugated roll preheating device is provided, comprising: two support plates, a rotating shaft disposed between the two support plates, a winding wheel rotatably connected to the outer surface of the rotating shaft, a resistance heating plate wound onto the outer surface of the winding wheel, a motor fixedly connected to the side walls of the two support plates, a rotating column fixedly connected to the output end of the motor, a contact groove formed inside the rotating column, a contact block contacting the inside of the contact groove, and the upper surface of the contact block fixedly connected to the resistance heating plate. This design allows the heating plate to be stably fixed, ensuring uniform and reliable heating, and effectively improving the preheating effect.

[0006] According to the peripheral heating corrugated roll preheating device, a drive device is fixedly connected to the side walls of the two support plates, and a drive shaft is rotatably connected to the output end of the drive device. The introduction of the drive device makes the operation of the entire device more stable, improves the preheating efficiency and the durability of the equipment.

[0007] According to the peripheral heating corrugated roll preheating device, a corrugated roll is fixedly connected to the outer surface of the drive shaft, and the corrugated roll is located inside the resistance heating plate. This structural design allows the corrugated roll to be directly heated, improving the preheating speed and efficiency.

[0008] According to the aforementioned peripheral heating corrugated roll preheating device, a heating module is fixedly connected to the side of the two support plates away from the drive device, and the output end of the heating module is fixedly connected to the drive shaft. The heating module configuration allows for more concentrated heating, improving preheating effect and energy utilization.

[0009] According to the aforementioned peripheral heating corrugated roll preheating device, a control device is provided below the heating module, and the control device is fixedly connected to the support plate. The control device is compatible with the motor and the resistance heating plate. The introduction of the control device makes the entire preheating process more intelligent, allowing heating parameters to be adjusted according to actual needs, thereby improving preheating efficiency and equipment flexibility.

[0010] According to the peripheral heating corrugated roll preheating device, a first fixed column and a second fixed column are arranged between the two support plates, and a second guide roller is rotatably connected to the outer surface of the first fixed column. This design increases the stability of the device and ensures the correct position of the corrugated roll during the preheating process.

[0011] According to the peripheral heating corrugated roll preheating device, a first guide roller is rotatably connected to the outer surface of the second fixed column, and the first guide roller and the second guide roller are adapted to each other. The guide roller ensures that the corrugated roll remains stable during the preheating process, preventing uneven preheating caused by vibration or displacement.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] This utility model includes a support plate, a rotating shaft, a winding wheel, a resistance heating plate, a motor, a rotating column, a contact groove, and a contact block. The winding wheel and the resistance heating plate work together, and the motor drives the rotating column to indirectly control the opening and closing of the resistance heating plate. This allows for flexible adjustment of the relative position between the resistance heating plate and the corrugated roller. When the resistance heating plate is unfolded and close to the corrugated roller, it efficiently heats the roller, increasing preheating speed and reducing waiting time, thereby improving production efficiency. During non-preheating periods or equipment maintenance, the resistance heating plate can be retracted to prevent damage from prolonged exposure or inconvenience to the surrounding environment, extending its service life. It also saves space and makes the overall layout of the equipment more compact and rational.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figures 1-4This utility model provides a technical solution: a peripheral heating corrugated roll preheating device, comprising: two support plates 1, a rotating shaft 8 disposed between the two support plates 1, a winding wheel 7 rotatably connected to the outer surface of the rotating shaft 8, the winding wheel 7 being used to wind up and unwind a resistance heating plate 14, realizing the winding and unwinding function of the resistance heating plate 14, so that it can be unfolded to heat the corrugated roll 3 when needed, and retracted to save space when not needed, a motor 10 fixedly connected to the side wall of the two support plates 1, a rotating column 11 fixedly connected to the output end of the motor 10, the motor 10 providing power for the rotation of the rotating column 11, enabling it to drive the contact block 13 to move, a contact groove 12 is provided inside the rotating column 11, the contact block 13 is in contact inside the contact groove 12, and the upper surface of the contact block 13 is fixedly connected to the resistance heating plate 14, through the cooperation of the contact groove 12 and the contact block 13, the rotation of the rotating column 11 can drive the resistance heating plate 14 to perform winding and unwinding actions.

[0023] A drive device 2 is fixedly connected to the sidewalls of the two support plates 1. A drive shaft 9 is rotatably connected to the output end of the drive device 2. The drive device 2 provides rotational power to the drive shaft 9, enabling it to drive the corrugated roller 3 to operate. The corrugated roller 3 is fixedly connected to the outer surface of the drive shaft 9, and the corrugated roller 3 is located inside the resistance heating plate 14. The corrugated roller 3 is a key component in corrugated cardboard processing. The resistance heating plate 14 can preheat it, allowing it to better form the cardboard during operation. A heating module 6 is fixedly connected to the side of the two support plates 1 away from the drive device 2, and the output end of the heating module 6 is fixedly connected to the drive shaft 9. The heating module 6 heats the drive shaft 9, thereby heating the corrugated roller 3 through heat conduction, playing an auxiliary heating role and ensuring that the corrugated roller 3 is heated evenly. A control device 5 is located below the heating module 6, and the control device 5 and the support plate 1... The fixed connection and control device 5 are used to control and adjust the operation of the entire preheating device to ensure that all components work together. The control device 5 is compatible with the motor 10 and the resistance heating plate 14. The control device 5 can control the start, stop and speed of the motor 10, thereby controlling the opening and closing action of the resistance heating plate 14 and its relative position to the corrugated roller 3. It can also control parameters such as the heating power of the resistance heating plate 14. A first fixed column 16 and a second fixed column 17 are set between the two support plates 1. The outer surface of the first fixed column 16 is rotatably connected to the second guide roller 15, and the outer surface of the second fixed column 17 is rotatably connected to the first guide roller 4. The first guide roller 4 and the second guide roller 15 are compatible. The first guide roller 4 and the second guide roller 15 are used to guide the transmission path of the cardboard, so that the cardboard can pass smoothly through the corrugated roller 3 for processing, and ensure the stable conveying of the cardboard during the preheating and forming process.

[0024] Working principle: The motor 10 starts according to the set parameters, driving the rotating column 11 to rotate. The interaction between the internal contact groove 12 and the contact block 13 of the rotating column 11 causes the resistance heating plate 14 fixed on the contact block 13 to be gradually released from the take-up roller 7. As the resistance heating plate 14 is released, it surrounds the outside of the corrugated roller 3, further heating the corrugated roller 3 and bringing it to the preheating temperature required for operation. At this time, the control device 5 continuously monitors the heating status of the resistance heating plate 14 and the temperature of the corrugated roller 3, and makes real-time adjustments according to the preset temperature range. For example, when the temperature is too high, the power of the resistance heating plate 14 can be appropriately reduced or the winding speed of the motor 10 can be increased to make the resistance heating plate 14 slightly away from the corrugated roller 3. When the temperature is too low, the power of the resistance heating plate 14 can be increased or the winding speed of the motor 10 can be slowed down to make the resistance heating plate 14 fit more closely to the corrugated roller 3. After the preheating device completes the preheating, the control device 5 controls the motor 10 to reverse and rewind the resistance heating plate 14 back onto the take-up roller 7, and then the heating module 6 and the motor 10 are turned off.

[0025] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
