Description

Technical Field

[0001] This utility model relates to the field of corrugated cardboard processing technology, and in particular to a preheating device for corrugated cardboard processing. Background Technology

[0002] A preheating device for corrugated cardboard processing, disclosed in publication number CN214563356U, specifically includes a steam generator, a throttling valve, a steam shell, a condensate tank, and a water pump, all connected sequentially by pipes to form a circuit. The steam shell has a rectangular longitudinal section, with its bottom surface inclined to the horizontal plane, making the bottom surface higher in the front and lower in the back. The top and bottom surfaces of the steam shell each have two or more air outlets, arranged sequentially from left to right. A first air inlet is located on the left side of the steam shell, and an air outlet is located at the bottom of the right side. A condensate tank is provided, allowing steam to enter the steam shell. Part of the steam is ejected from the air outlets, while the other part is discharged from the first air outlet into the condensate tank. Water is stored in the condensate tank through inlet and outlet to exchange heat with the steam, causing it to condense into water, which is then fed back into the steam generator along with the water in the condensate tank for steam recovery and reuse. In existing preheating devices for corrugated cardboard processing, some steam condenses on the surface of the corrugated cardboard during the heating process, resulting in water droplets adhering to the surface. Manually cleaning these water droplets is inconvenient, time-consuming, and labor-intensive. Therefore, we propose a preheating device for corrugated cardboard processing. Utility Model Content

[0003] The purpose of this invention is to solve the problem that in the existing technology, during the heating process of the preheating device for corrugated cardboard processing, some steam will condense on the surface of the corrugated cardboard, resulting in water droplets adhering to the surface of the corrugated cardboard. Manually cleaning the water droplets is inconvenient, time-consuming and laborious. Therefore, this invention proposes a preheating device for corrugated cardboard processing.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] Design a preheating device for corrugated cardboard processing, including a water tank. The upper end of the water tank is provided with an outer ring, and brackets are fixedly installed on both sides of the outer ring. The lower ends of the brackets are fixedly connected to the water tank. The top of the water tank has several equidistantly distributed ventilation slots that penetrate the water tank. A heating element is fixedly installed inside the water tank, and a water inlet pipe is fixedly installed and connected to the outside of the water tank.

[0006] A side plate is fixedly installed at one end of the outer ring. Four suction cups are arranged in a four-corner pattern inside the outer ring. A pipe is rotatably installed through the side plate. One end of the pipe is connected to and fixedly installed with a connecting pipe. A negative pressure mechanism is installed on the outer ring and is connected to one end of the pipe. A driving mechanism is installed on the water tank and is connected to the pipe. Several evenly distributed ventilation slots are opened at the lower end of the outer ring, and all ventilation slots penetrate the outer ring.

[0007] Furthermore, a sealing gasket is fixedly connected to the lower end of each suction cup.

[0008] Furthermore, the negative pressure mechanism includes a negative pressure pump, which is fixedly installed on the outer sleeve ring. The air inlet end of the negative pressure pump is connected to and fixedly installed with an air inlet pipe. The other end of the air inlet pipe is rotatably installed at one end of the pipeline. The air inlet pipe is connected to the pipeline, and a valve is installed on the air inlet pipe.

[0009] Furthermore, a temperature detector is installed on the outside of the water tank.

[0010] Furthermore, the drive mechanism includes a motor, which is fixedly mounted on the water tank. Pulleys are fixedly mounted on both the output shaft end of the motor and the pipe, and a belt is installed between the two pulleys.

[0011] The present invention discloses a preheating device for corrugated cardboard processing, which has the following advantages: The device absorbs gas in the pipeline by setting a negative pressure mechanism, thereby creating a negative pressure inside the pipeline and the suction cup. This creates a negative pressure state in both the connecting pipe and the suction cup, thus adsorbing the corrugated cardboard onto the suction cup. By adding a certain amount of water to the water tank and heating the water in the tank with a heating element, steam is generated in the water tank. The steam passes through the venting groove and then through the venting groove on the outer ring, thereby preheating one side of the single-sided corrugated cardboard. This improves the adhesion between the single-sided corrugated cardboard and the facing paper. After preheating, the pipe is rotated, allowing the corrugated cardboard to rotate synchronously with the pipe. This centrifugal force is used to shake off the water droplets on the surface of the corrugated cardboard, thus replacing manual cleaning and saving manpower. Attached Figure Description

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0017] Example 1:

[0018] Reference Figure 1-3 A preheating device for corrugated cardboard processing includes a water tank 1. An outer ring 3 is provided at the upper end of the water tank 1. Supports 2 are fixedly installed on both sides of the outer ring 3, and the lower ends of the supports 2 are fixedly connected to the water tank 1. Several equidistantly distributed ventilation slots 4 are opened at the top of the water tank 1, penetrating the water tank 1. Heating elements 5 are fixedly installed inside the water tank 1, and a water inlet pipe 6 is fixedly installed and connected to the outside of the water tank 1. A side plate 7 is fixedly installed at one end of the outer ring 3. Four suction cups 8 are arranged at four corners inside the outer ring 3. A pipe 9 is rotatably installed through the side plate 7, and one end of the pipe 9 is connected and fixedly installed with a connecting pipe 10. A negative pressure mechanism is installed on the outer ring 3, connected to one end of the pipe 9. A driving mechanism is installed on the water tank 1, connected to the pipe 9. Several evenly distributed ventilation slots 17 are opened at the lower end of the outer ring 3, all penetrating the outer ring 3.

[0019] Working principle: The cardboard is placed inside the outer ring 3 and in contact with the four suction cups 8. The negative pressure mechanism absorbs the gas in the pipe 9 and creates a negative pressure inside it, thus creating a negative pressure state in both the connecting pipe 10 and the suction cups 8. This allows the corrugated cardboard to be adsorbed onto the suction cups 8. A certain amount of water is added to the water tank 1, and the water in the water tank 1 is heated by the heating element 5. Steam is generated in the water tank 1 and passes through the venting groove 4 and then through the venting groove 17 on the outer ring 3. This steam preheats one side of the single-sided corrugated cardboard, thereby improving the adhesion between the single-sided corrugated cardboard and the face paper. After preheating, the pipe 9 is rotated, allowing the corrugated cardboard and the pipe 9 to rotate synchronously. This centrifugal force is used to shake off the water droplets on the surface of the corrugated cardboard, thus replacing manual cleaning and saving manpower.

[0020] Example 2:

[0021] Reference Figure 1-3In another preferred embodiment of this utility model, the difference from Embodiment 1 is that a sealing gasket 11 is fixedly connected to the lower port of the suction cup 8. The negative pressure mechanism includes a negative pressure pump 12, which is fixedly installed on the outer ring 3. The air inlet end of the negative pressure pump 12 is connected to and fixedly installed with an air inlet pipe 13. The other end of the air inlet pipe 13 is rotatably installed at one end of the pipe 9. The air inlet pipe 13 is connected to the pipe 9, and a valve is installed on the air inlet pipe 13. A temperature detector is installed outside the water tank 1. The drive mechanism includes a motor 14, which is fixedly installed on the water tank 1. Pulleys 15 are fixedly installed on both the output shaft end of the motor 14 and the pipe 9. A belt 16 is installed between the two pulleys 15.

[0022] Working principle: By setting a sealing gasket 11 at the lower end of the suction cup 8, the sealing between the suction cup 8 and the cardboard can be improved. By starting the negative pressure pump 12 and drawing air into the air inlet pipe 13 to a negative pressure state, the suction cup 8 is also in a negative pressure state, thereby adsorbing the cardboard. The motor 14 drives the pulley 15 to rotate, which in turn drives the belt 16 to the pipe 9. Thus, the pipe 9, the connecting pipe 10, the suction cup 8, and the cardboard rotate synchronously, allowing the corrugated cardboard to rotate synchronously with the pipe 9, thereby using centrifugal force to shake off the water droplets on the surface of the corrugated cardboard.

[0023] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
