Description

Technical Field

[0001] The utility model relates to the technical field of cardboard production, in particular to a base paper water-extraction agent smearing device for degradable cardboard. Background Art

[0002] As global environmental issues become increasingly severe, the demand for environmentally friendly materials continues to grow. In the packaging industry, traditional plastic packaging is limited by its non-degradability, prompting the use of environmentally friendly materials such as biodegradable cardboard. However, these environmentally friendly materials often suffer from insufficient water resistance during use, limiting their application. Therefore, when producing biodegradable cardboard, a layer of water-repellent (hydrophobic agent) is often added to its surface to improve its water resistance.

[0003] The existing base paper water-repellent coating device for moisture-proof and easily degradable corrugated paper box production (Announcement No.: CN219547435U) includes a coating tank, a liquid inlet pipe to input water-repellent into the coating tank, and a residual discharge pipe to discharge the residual water-repellent in the coating tank; it also includes a roller, two purge pipes, two drying pipes, multiple nozzles, an adjustable bracket and an air source. The roller presses the base paper into the water-repellent. The two purge pipes and two drying pipes are installed on the coating tank through the adjustable bracket. The two purge pipes and two drying pipes are respectively arranged above the base paper, and another purge pipe and another drying pipe are arranged below the base paper. Multiple nozzles are installed on the two purge pipes and the two drying pipes. The air source delivers high-pressure cold air and high-pressure hot air to the two purge pipes and the two drying pipes respectively:

[0004] In the above scheme, since the base paper is completely immersed in the coating, thicker or more absorbent cardboard may absorb too much coating, causing the cardboard to become heavier, softer, or even deformed, seriously affecting its physical properties. Secondly, the impregnated cardboard takes a long time to dry, which not only consumes a lot of energy, but also reduces production efficiency and increases production costs. The operation of the impregnation method requires precise control of the impregnation time and depth, otherwise it is easy to cause uneven or excessive coating, which increases the difficulty of operation and technical requirements. Utility Model Content

[0005] The utility model aims to solve the shortcomings in the prior art and proposes a base paper water-extraction agent smearing device for degradable paperboard.

[0006] In order to achieve the above purpose, the present invention adopts the following technical solutions:

[0007] A device for applying a water-extraction agent to base paper for degradable cardboard comprises an operating table, on which a feed roller and a receiving roller are rotatably mounted, two mounting brackets are fixedly mounted, one of which is provided with two drive motors, and a driving shaft is fixedly mounted on the output end of each shaft of the drive motor, and an application roller is fixedly mounted on the driving shaft;

[0008] Two shielding covers are also fixedly installed on the mounting frame, and a wetting mechanism is provided on the operating table;

[0009] Two installation chambers are fixedly installed on the other installation frame, and a drying mechanism and a driving mechanism are arranged inside the two installation chambers.

[0010] As a further solution of the present invention, the wetting mechanism includes a hollow tube, a temporary storage box for smearing material and a water pump. There are two hollow tubes, and both hollow tubes are fixedly installed inside the corresponding shielding covers. Nozzles are evenly and equidistantly inlaid on the hollow tubes. Delivery pipes are inlaid on both hollow tubes, and the other end of the delivery pipes is fixedly installed on the output end of the water pump. The water pump and the temporary storage box for smearing material are connected by an extraction pipe.

[0011] As a further solution of the present invention, the nozzle is exposed from the shielding cover and can directly spray the solution onto the coating roller.

[0012] As a further solution of the present invention, the drying mechanism includes an installation shaft and a heating wire. The installation shaft is equidistantly and evenly rotated and installed inside the installation chamber. The installation shaft is fixedly installed with a blowing fan blade, and the heating wire is embedded and installed at the air inlet of the installation chamber.

[0013] As a further solution of the present invention, the driving mechanism includes a driven shaft, a synchronous belt is provided between the driven shaft and the driving shaft through a pulley sleeve, vertical bevel gears are fixedly installed on the driving shaft at equal intervals, and transverse bevel gears are fixedly installed at corresponding positions on the mounting shaft, and the vertical bevel gears are in a meshing relationship with the transverse bevel gears.

[0014] As a further solution of the present invention, dustproof nets are embedded and installed at the upper and lower ends of the two installation chambers.

[0015] Compared with the prior art, the present invention has the following beneficial effects:

[0016] 1. In the utility model, two smear rollers are used through the operating table, mounting frame, shielding cover, smear roller and wetting mechanism, which can ensure that both sides of the base paper can be evenly coated with the water-extraction agent. Moreover, since the nozzles are evenly distributed and sprayed directly on the smear roller, the water-extraction agent on the smear roller is very evenly distributed, thereby ensuring the consistency of the smearing on both sides of the base paper.

[0017] 2. In the present invention, through the drying structure, the fan blades in the two installation chambers can dry both sides of the base paper at the same time. The heating wire heats the incoming air, so that the blown air flow has a certain temperature, thereby accelerating the drying process of the water-extracting agent and shortening the drying time. The double-sided drying design can ensure that the moisture on both sides of the base paper is evenly removed, preventing the paper from deforming or warping due to single-sided drying, and improving the flatness and aesthetics of the cardboard.

[0018] 3. In the utility model, the driving mechanism utilizes the power provided by the driving motor of the coating roller to drive multiple blowing fan blades to rotate synchronously, which simplifies the structure of the system, reduces the number of driving sources, reduces the complexity of the equipment and maintenance costs, and the drying mechanism utilizes the existing power and does not require an additional motor or other driving source, reducing the loss in the energy conversion process and further improving the energy efficiency of the system.

[0028] Reference Figure 1 - Figure 5 A device for applying a water-extracting agent to base paper for degradable cardboard includes an operating table 1, on which a feed roller 2 and a receiving roller 3 are rotatably mounted. The feed roller 2 is used to introduce the base paper to be processed, and the receiving roller 3 is used to collect the processed paper. Other methods can also be used for feeding and receiving. For example, thicker paper can be fed by push-type feeding, which is not limited here.

[0029] Two mounting brackets 4 are fixedly mounted on the operating table 1, one of which is provided with two drive motors 11. A driving shaft 17 is fixedly mounted on the output end of the shaft of the drive motor 11, and a smear roller 6 is fixedly mounted on the driving shaft 17. The drive motor 11 provides a power source to enable the device to operate, and the driving shaft 17 transmits the rotational motion of the motor to the smear roller 6, so that the smear roller 6 evenly applies the water-extraction agent on the base paper.

[0030] Two shielding covers 5 are also fixedly mounted on the mounting frame 4. A wetting mechanism is provided on the operating table 1. The shielding cover 5 can prevent the water-extraction agent from splashing out and keep the working environment clean. The wetting mechanism is used to evenly distribute the water-extraction agent on the application roller 6 to ensure the uniformity of the distribution of the water-extraction agent, thereby ensuring the application effect.

[0031] Two installation chambers 14 are fixedly mounted on the other installation frame 4 , and a drying mechanism and a driving mechanism are provided inside the two installation chambers 14 .

[0032] The wetting mechanism includes a hollow tube 15, a temporary storage box for smear material 10 and a water pump 8. There are two hollow tubes 15, and both hollow tubes 15 are fixedly installed inside the corresponding shielding cover 5. Nozzles 16 are evenly and equidistantly inlaid on the hollow tubes 15.

[0033] The hollow tube 15 is used as a pipeline for conveying the water-extraction agent, the temporary storage box 10 stores the water-extraction agent, and the water pump 8 is responsible for pumping the water-extraction agent to the corresponding position. The two hollow tubes 15 correspond to the two coating rollers 6 respectively, and the nozzle 16 is used to spray the water-extraction agent evenly;

[0034] The two hollow tubes 15 are both inlaid with a delivery pipe 7 , and the other end of the delivery pipe 7 is fixedly installed at the output end of the water pump 8 . The water pump 8 and the temporary storage box 10 of the smear are connected through an extraction pipe 9 .

[0035] The water pump 8 can smoothly extract the water repellent inside the temporary storage box 10 through the extraction pipe 9, and then transport it to the inside of the hollow tube 15 through the delivery pipe 7, and then evenly spray it out through the nozzle 16;

[0036] The nozzle 16 is exposed from the shielding cover 5 and can directly spray the solution on the coating roller 6. The nozzle 16 is exposed to the outside to facilitate spraying the water-extracting agent, which can ensure that the water-extracting agent can evenly cover the surface of the coating roller 6.

[0037] The drying mechanism includes a mounting shaft 21 and a heating wire 24. The mounting shaft 21 is used to fix the blowing fan blades 22, and the heating wire 24 is a heating element. The mounting shaft 21 is equidistantly and evenly rotated and installed inside the mounting chamber 14. The blowing fan blades 22 are fixedly installed on the mounting shaft 21. The rotation of the mounting shaft 21 can drive the blowing fan blades 22 to rotate, and then the blowing fan blades 22 generate airflow to dry the paper. The heating wire 24 is embedded in the air inlet of the mounting chamber 14. The heating wire 24 heats the incoming air so that the blown gas has a certain temperature, which can improve the drying efficiency.

[0038] In this embodiment, the size and orientation of the fan blades 22 need to be selected according to actual needs. The ones shown in the figure are just for illustration and not for reality.

[0039] The driving mechanism includes a driven shaft 18, and a synchronous belt 12 is provided between the driven shaft 18 and the driving shaft 17 through a pulley 13. Vertical bevel gears 19 are fixedly installed on the driving shaft 17 at equal intervals, and a transverse bevel gear 20 is fixedly installed at the corresponding position of the mounting shaft 21. The vertical bevel gear 19 is in a meshing relationship with the transverse bevel gear 20.

[0040] The driven shaft 18 receives power transmission from the driving shaft 17 through the synchronous belt 12, so that the driven shaft 18 rotates synchronously, and then the vertical bevel gear 19 thereon moves synchronously. The vertical bevel gear 19 is in a meshing relationship with the transverse bevel gear 20, so the transverse bevel gear 20 can rotate synchronously, and then the mounting shaft 21 and the blowing fan blades 22 rotate, and the drying activity can be carried out without the need for multiple external drive sources.

[0041] Dust-proof nets 23 are embedded at the upper and lower ends of the two installation chambers 14 to prevent external dust from entering the interior of the installation chambers 14 and affecting the quality of paper.

[0042] The working process of the present invention is that the base paper is fed into the device through the feed roller 2 , and the feeding method can be selected according to the actual situation so that the base paper is in the space between the two coating rollers 6 and the two installation chambers 14 .

[0043] The driving motor 11 is started and drives the smear roller 6 to rotate through the driving shaft 17. When the base paper passes through the smear roller 6, the water-extracting agent on the smear roller 6 will be evenly coated on the base paper. The water pump 8 simultaneously extracts the water-extracting agent from the smear material storage box 10, and transports it to the delivery pipe 7 through the extraction pipe 9. Then, it is evenly sprayed on the smear roller 6 through the nozzle 16 on the hollow tube 15, ensuring that the two smear rollers 6 are stably in a wet state to ensure the smearing effect.

[0044] After being coated with a water-extraction agent, the base paper enters the space between the two mounting chambers 14. The blower blades 22 on the mounting shaft 21, linked to the coating mechanism via a drive mechanism, spray air heated by the heating wire 24 onto the base paper, rapidly drying it. The size and angle of the blower blades 22 can be adjusted to achieve optimal drying results. The dried base paper is then reeled up by the delivery roller 3, becoming the finished product.

[0045] The above shows and describes the basic principles, main features and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The above embodiments and descriptions are merely illustrative of the principles of the present invention. Various changes and improvements may be made to the present invention without departing from the spirit and scope of the present invention. Such changes and improvements are intended to fall within the scope of the present invention. The scope of protection claimed in this invention is defined by the appended claims and their equivalents.
