Description

Technical Field

[0001] This utility model relates to the field of corrugated paper production technology, specifically to a five-layer corrugated cardboard manufacturing equipment. Background Technology

[0002] Corrugated cardboard is a multi-layered laminate, also known as corrugated paperboard. It is made of at least one layer of corrugated paper and one layer of linerboard (also called boxboard) bonded together, and has good elasticity and extensibility. It is mainly used to manufacture cartons, carton fillings, and other packaging materials for fragile goods.

[0003] Chinese Patent CN206154783U discloses a five-layer corrugated cardboard manufacturing equipment with preheating function, including a face paper unwinding section, a face paper adjusting section, a face paper correcting section, a pressing and drying section, a corrugated paper a forming section, a corrugated paper a correcting section, a corrugated paper b forming section, a corrugated paper b correcting section, a glue applicator, and a main drive roller disposed between the face paper correcting section and the pressing and drying section, face paper, corrugated paper a, and corrugated paper b; the face paper adjusting section includes a drive roller disposed above the face paper unwinding section, a conveyor bridge, and... The guide roller a, which works in conjunction with the drive roller to form a parabolic segment of the face paper, contacts the upper surface of the conveyor bridge. Sensors a and b, used to control the linear speed ratio between the drive roller and the main drive roller, are installed on the conveyor bridge. The corrugated paper a and corrugated paper b correction sections are located at the front end of the laminator. The machine also includes a preheating roller, a preheating plate a, and a preheating plate b. This design overcomes the problems of difficult face paper correction, easy damage to the face paper during long-distance pulling, difficulty in stable control of the face paper conveying speed, insufficient strength of the produced paperboard, and failure to meet the production requirements of different layer numbers of paperboard.

[0004] However, in the above technical solution, the active roller is only used in conjunction with the guide roller b to form a parabolic shape of the face paper on the conveyor bridge. This makes the face paper loose when it enters the suction correction device, which is easy to correct. However, the device is equipped with a preheating roller, a preheating plate a, and a preheating plate b to preheat and dry the face paper and the two layers of core paper. During the drying process, the core paper on the preheating plate b, which is in the middle position, is subjected to heat radiation from the upper and lower preheating structures, which causes more water loss and makes it easy to cause quality problems in subsequent production. Utility Model Content

[0005] The purpose of this invention is to address the problems existing in the background technology by proposing a five-layer corrugated cardboard manufacturing equipment.

[0006] The technical solution of this utility model is as follows: A five-layer corrugated cardboard manufacturing equipment includes a frame connected to a preheating structure, which includes a heating roller, a first heating plate, and a second heating plate, which are vertically mounted on the frame from top to bottom; a temperature control component connected to the frame, which includes a microwave moisture sensor, a temperature sensor, a diversion pipe, spray heads, and a recycling component, which is mounted on the frame.

[0013] Compared with the prior art, the above-mentioned technical solution of this utility model has the following beneficial technical effects:

[0014] In this invention, a temperature control component is installed on the first heating plate located between the heating roller and the second heating plate. The component detects the moisture content of the core paper on the first heating plate and sends the information to an external control device. The control device then controls the spray nozzles to spray water mist for humidification, preventing the core paper from having too low a moisture content, which could cause problems during subsequent pressing and drying.

[0024] In an optional embodiment, the mounting frame consists of a frame 10 and multiple mounting brackets.

The mounting brackets are connected to the frame 10 by bolts to facilitate later maintenance. The mounting brackets are arranged sequentially from the feed end to the discharge end of the machine frame 1 as a first mounting bracket 11, a second mounting bracket 12, and a third mounting bracket 13. The first mounting bracket 11 is connected to a diversion pipe 7, the third mounting bracket 13 is equipped with a microwave moisture sensor 5 and a temperature sensor 6, and the second mounting bracket 12 is connected to the recycling component 9.

[0025] In an optional embodiment, the spray head 8 is tilted at 45 degrees, and the spraying direction of the spray head 8 forms a 135-degree angle with the movement of the core paper. The setting of the angle between the spray head 8 and the moving direction of the core paper can increase the contact time and range between the water mist and the core paper, and avoid poor humidification effect due to excessive contact time.

[0026] In an optional embodiment, the recovery unit 9 consists of a suction head 14, a connecting pipe 15, a centrifugal fan 16, an air-water separator 17, an air inlet pipe 18, a drain pipe 19, an exhaust pipe 20, and an adjusting component.

The air inlet end of the air-water separator 17 is connected to the air inlet pipe 18, and the air inlet pipe 18 is connected to the suction head 14. The suction head 14 has L-shaped connecting plates connected to both ends, and the adjusting component is connected to the suction head 14. The air outlet end and the water outlet end of the air-water separator 17 are respectively connected to the exhaust pipe 20 and the drain pipe 19. The exhaust pipe 20 is connected to the air inlet end of the centrifugal fan 16.

[0027] In an optional embodiment, the suction head 14 is tilted at an angle of 30 degrees; the angle of the suction head 14 can be adjusted to fit different sizes of corrugated paper.

[0028] In an optional embodiment, the adjusting component includes a telescopic device 21, a movable frame 22, and symmetrically arranged tilting components. The telescopic device 21 is connected to the second mounting frame 12. The telescopic device 21 may be, but is not limited to, an electric telescopic rod.

[0029] In an optional embodiment, the tilting member includes an adjusting handle 23, a moving rod 24, and an elastic member 25. The moving rod 24 is slidably connected to the connecting plate. One end of the moving rod 24 is connected to the adjusting handle 23, and the other end of the moving rod is slidably connected to the limiting hole. The elastic member 25 is sleeved on the outside of the moving rod 24, and both ends of the elastic member 25 are respectively connected to the protrusions on the moving rod 24 and the connecting plate. The elastic member 25 may be, but is not limited to, a spring.

[0030] In summary, when this utility model is used, the two processed core papers and the face paper are gradually moved onto the first clamping plate, the second heating plate 4, and the heating roller 2 by the conveying equipment. After being heated by the three heating devices, the core paper and the face paper enter the pressing and drying equipment. During preheating, the microwave moisture sensor 5 and the temperature sensor 6 can detect the moisture content and temperature of the core paper in the middle position. Water is supplied by an external water supply device into the diversion pipe 7 and sprayed through the spray head 8 to generate water mist to humidify the core paper, preventing the middle core paper from becoming too dry due to the heat radiation from the heating roller 2 and the second heating plate 4. The water mist combines with the hot air to produce humid air. After the centrifugal fan 16 is started, it generates negative pressure and draws air through the suction head 14. Humid and hot air enters through the connecting pipe 15 and the air inlet pipe 18 and enters the air-water separator 17, where moisture and air are separated. The air can enter the centrifugal fan 16 through the exhaust pipe 20 and then be returned or discharged directly through an external pipe. The water is collected and discharged through the drain pipe 19 at the bottom of the air-water separator 17. For corrugated cardboard of different sizes, the height and angle of the suction head 14 can be adjusted. The height of the moving frame 22 and the suction head 14 can be adjusted by the telescopic device 21. After pulling the adjusting handle 23 to stretch the elastic element 25, the suction head 14 can be rotated with its rotating connection and the center. The limiting hole on the moving frame 22 and the moving rod 24 cooperate to limit it to a fixed angle.

[0031] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited thereto. Various changes can be made within the scope of knowledge possessed by those skilled in the art without departing from the spirit of the present invention.
