Description

A base paper automatic humidifying device

Technical Field

The invention relates to the field of base paper humidification, and in particular to an automatic base paper humidification device.

Background technique

The background technology of the food packaging bag base paper humidification device mainly stems from the high requirements of the food packaging industry on the quality and stability of raw materials. As a packaging material that directly contacts food, the quality and safety of food packaging bags have an important impact on the quality and shelf life of food. As the main raw material of food packaging bags, the control of the moisture content of base paper is crucial to ensure the quality of packaging bags.

In the production process of food packaging bags, the moisture content of the base paper directly affects the subsequent processing links such as the forming, printing, and sealing of the packaging bags. If the moisture content of the base paper is too low, the packaging bag may be fragile and easy to tear, affecting the integrity of the packaging; while if the moisture content is too high, the packaging bag may become soft and deformed, affecting the appearance and practicality. Therefore, in order to ensure the quality and stability of food packaging bags, the moisture content of the base paper must be accurately controlled.

The existing humidification devices still need to be improved in terms of humidification uniformity. Since the base paper is affected by many factors during the humidification process, such as humidification amount, nozzle distribution, wind speed, etc., the humidification effect is often uneven and the precise control of the humidification amount is insufficient. This unevenness may cause the moisture content of some base paper to be too high or too low, thus affecting the quality of food packaging bags.

Therefore, it is particularly important to design a base paper humidification device that can evenly humidify the base paper and accurately control the humidification amount.

Optionally, drainage grooves are provided on the sides of the spray conveyor belt.

Optionally, an infrared thermometer is provided on the lifting frame, and an infrared moisture meter is provided on the atomization box.

Compared with the prior art, the beneficial effect of the present invention is that the rollers on the roller device can smooth the bent base paper that has been stored for a long time to facilitate humidification. The purpose of heating the base paper before humidification is because the base paper has been stored in a base paper warehouse with high humidity for a long time, which makes the moisture content of the inner and outer rolls of the base paper different. In addition, because the moisture content on the same side of the base paper is also different, it is easy to cause partial over-humidification or insufficient humidification during humidification.

Heating the base paper uniformly allows the moisture content of each part on the same surface to be controlled within a uniform humidity range, making it easier to humidify evenly. After the base paper is heated, its surface temperature rises, which makes the subsequent spray humidification more effective. When the water mist contacts the hot paper surface, the moisture is more easily absorbed and evenly distributed, thereby improving the humidity uniformity of the paper. Heating and humidification helps to stretch and soften the paper fibers, making the paper softer and smoother, and improving its printing and writing performance. At the same time, the bonding force between the humidified paper fibers is enhanced, and the strength of the paper will also be improved.

Compared with traditional humidification methods, the method of heating first and then spraying can make more efficient use of water resources and reduce waste. In addition, since the heating process may use efficient energy, the entire humidification process may also be more energy-efficient. By adjusting the heating temperature and the spraying amount, the humidification amount of the paper can be precisely controlled.

The method of heating first and then spraying humidification can make the paper maintain a certain stability during the humidification process and reduce deformation and curling.

The spray head is set to rotate so that the spray coverage area is larger and the spray head setting is reduced. At the same time, the use of spray can improve the humidification efficiency and make the humidification range more uniform. A drainage groove is set in the atomization box to drain the liquefied water of the spray, ensuring that there is no liquefied water in the atomization box to cause excessive humidification.

The heating device and the spray device are equipped with an infrared moisture meter, which can conveniently detect the moisture on the base paper to help users judge the humidification condition of the base paper.

Detailed ways

The following will clearly and completely describe the technical solutions of various embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

An embodiment of the present invention provides a base paper automatic humidification device.

Embodiment 1: The base paper humidifying device comprises a roller device 1, a heating device 2 and a spray device 3. The roller device 1 is provided with a support frame, and a support block 13 is provided on the support frame. The support block 13 is a trapezoidal shape with a narrow top and a wide bottom.

The support block 13 is provided on the opposite side of the support frame, and a roller 11 is provided on the support block 13. The two side shafts of the roller 11 are provided in the rotating shaft hole. The roller 11 can be removed from the support block 13, and the base paper 10 is provided on the roller 11.

The support frame of the roller device 1 is provided with rollers 14, which are arranged correspondingly up and down. The rollers 14 rotate up and down to flatten the base paper 10 on the roller 11. Because the base paper is curled and stored in the warehouse for a long time, the rollers 14 can properly flatten the base paper. A pressure sensor 12 is provided on the support block 13, and the pressure sensor 12 can sense the weight of the entire base paper.

The heating device 2 is provided with a conveyor belt 21 and a heating roller. A lifting frame 20 is provided at the end point of the conveyor belt 21. The lifting frame 20 is provided with a heating roller 22 with a lifting height. The heating roller 22 can adjust the gap between the upper and lower heating rollers. A rotating long axis is provided on both sides of the heating roller 22. Lifting slots are provided on both sides of the lifting frame 20. The rotating long axis moves in the lifting slots. A lifting block 28 is provided on the rotating long axis. A lifting shaft 29 is provided on the lifting block 28. A telescopic rod is provided on the top of the lifting shaft 29. The extension length of the telescopic rod is controlled by the lifting motor 23 on the top of the lifting frame 20. The lifting frame 20 is also provided with an air outlet 26, and a heater 24 is provided on the back plate of the air outlet 26. There are three heaters 24, and an air inlet is provided on the heater 24. The air enters the heater 24 from the air inlet. A heating wire is provided inside the heater 24. The incoming air is heated by the heating wire and blown out from the air outlet 26 of the lifting frame 20. A layer of filter is provided on the inner side of the air outlet 26, and the filter can prevent dust from falling. The air outlet 26 is provided with an oblique air outlet slot 27, and hot air is blown out from the air outlet slot 27. An infrared thermometer 25 is provided on the top of the heating roller 22.

A spray conveyor belt 33 is arranged on the support frame of the spray device 3, a square atomizing box is arranged on the conveyor belt, an atomizing water tank 30 is arranged on one side of the box, two spray pipes extend from the atomizing water tank 30 on the top cover of the atomizing box, a spray water pipe is arranged in the top cover of the atomizing box, four spray heads 32 are arranged in the atomizing box, the spray heads 32 are connected to the spray water pipe, a humidity detector is arranged in the atomizing box, a spray base is arranged on the spray head 32, a spray rotating shaft 34 is arranged on the spray base, four protruding spray shafts 35 are arranged on the lower side of the spray rotating shaft 34, and a plurality of spray ports 36 are opened on each spray shaft 35, and a drainage groove is opened on the side of the spray conveyor belt 33. An infrared moisture meter 31 is arranged above the end of the spray conveyor belt 33 to detect the moisture content on the base paper 10 after the spraying is completed. An atomizing plate is arranged in the spray water tank 30, and the pure water is atomized and sent into the atomizing box through the pipeline.

When in use, the base paper 10 on the roller device 1 is smoothed by the roller 14 and transported to the conveyor belt 21. The smoothed base paper 10 follows the conveyor belt 21 to the bottom of the air outlet 26. At this time, hot air blows from the air outlet slot 27 onto the conveyor belt 21, and the hot air preheats the base paper 10. At the same time, the hot air blown down will blow away the dust on the base paper 10. The base paper 10 on the conveyor belt 21 is slowly and evenly heated by the upper and lower heating rollers 22. At this time, the temperature on the plane of the base paper 10 is consistent, and the moisture content on the base paper 10 reaches the set value. The heated base paper 10 passes through the infrared thermometer above to detect the surface temperature and moisture content of the paper.

After uniform heating, the base paper 10 is transported from the heating roller 22 to the spray conveyor belt 33 and slowly enters the atomizing box. The humidity detector in the atomizing box detects the humidity inside the box and adjusts the spray volume. The spray shaft 34 on the spray head 32 rotates to rotate the entire spray head 32. At this time, a large amount of atomized water is sprayed from the spray port 36. The spray head 32 rotates to spray the atomized water evenly on the base paper 10. The residual water on the side wall of the atomizing box will flow down the side wall to the drainage groove and be discharged. After spray humidification, the base paper 10 passes through the infrared moisture meter 31 to detect the moisture content thereon.

The pressure sensor 12 of the device arranged on the roller device 1 will sense the pressure increase after the base paper 10 is installed. At this time, the heating device 2 and the spray device 3 start to work, the air outlet 26 starts to discharge air, the spray head starts to spray, and the humidity in the atomization box starts to increase. At the same time, the roller gap of the roller 14 can be manually adjusted to adapt to base papers 10 of different thicknesses. As the pressure on the pressure sensor 12 no longer changes, it means that the base paper 10 on the roller 11 has been used up. After a few minutes, the heating device 2 and the spray device 3 stop working. The purpose of these few minutes is to continue to heat and spray the base paper at the end until all the base paper 10 is humidified, which is also convenient for workers to replace new base paper humidification within these few minutes. This design can save resources, and spraying pure water can also greatly improve the utilization of water resources.

Embodiment 2: The roller 14 can be configured as an electrostatic roller, which can remove static electricity on the base paper 10 while smoothing the base paper 10. Other features are the same as those of Embodiment 1.

Embodiment 3: A re-working atomizing box is arranged at the rear end of the atomizing box, and its function is to perform secondary humidification on the base paper that has not been fully humidified for the first time, so as to control the moisture content of the base paper within the set range for subsequent processing. Other features are consistent with those of Embodiment 1.
