[0032] The following will specifically describe the preferred embodiments of the present invention in conjunction with the accompanying drawings. The accompanying drawings form a part of this application and are used together with the embodiments of the present invention to explain the principles of the present invention, rather than to limit the scope of the present invention

[0033] A glue-applying raw material stirring device for wood substrate sheets in this embodiment relates to the technical field of plywood preparation. By fixing both ends of the main stirring shaft, two fulcrums are provided for the main stirring shaft, improving the impact resistance of the main stirring shaft and preventing the main stirring shaft from being damaged

[0034] Please refer to Figures 1 to 6 , a glue-applying raw material stirring device for wood substrate sheets in this embodiment includes: a stirring tank 100, a main stirring component 200, and a sub-stirring component 300. The stirring tank 100 includes a tank body 110 for storing glue and a heating jacket 120. The heating jacket 120 is sleeved outside the tank body 110. The heating jacket 120 can heat the glue, thereby reducing its viscosity and reducing the resistance borne by the equipment during the stirring process, making the stirring easier

[0035] The main stirring component 200 includes a rotatable main stirring paddle 210. The bottom of the main stirring paddle 210 passes through the tank body 110 and is rotatably connected to the ground. It can share the overall weight of the main stirring paddle 210, reduce the rotation resistance and friction, thereby reducing the wear of the stirring equipment. It can also provide a second support point for the main stirring paddle 210, enhancing the impact resistance and strain resistance of the main stirring paddle 210 and protecting the main stirring paddle 210 from being damaged

[0036] The sub-stirring component 300 includes a rotatable sub-stirring paddle 310. The sub-stirring paddle 310 is arranged relative to the inner wall of the tank body 110, which can push the glue at the relatively edge part in the tank body 110 to flow, making the flow rate of the glue in contact with the inner wall of the tank body 110 much greater than that of the glue in the middle of the tank body 110, and preventing the glue from adhering to the inner wall of the tank body 110. The driving power of the sub-stirring paddle 310 is relatively smaller than that of the main stirring paddle 210. During the heat preservation process of the glue, the sub-stirring paddle 310 can replace the main stirring paddle 210, prevent the glue from sticking to the inner wall of the tank body 110, shorten the working duration of the main stirring paddle 210, and reduce the intensity of the external impact and wear on the main stirring paddle 210, protecting the main stirring paddle 210 from being damaged

[0037] In some embodiments, please refer to Figure 4, the heating jacket 120 includes a jacket body 121 which is arranged around the bottom of the tank body 110. The jacket body 121 is arranged to fit the inner wall of the tank body 110, so that efficient heat conduction can be achieved between the jacket body 121 and the tank body 110. A sandwich layer 122 for storing a medium is provided in the jacket body 121. The medium can be steam, water or oil. The medium can heat the surface of the jacket body 121 evenly, ensuring that the adhesive liquid in the mixing tank 100 is evenly heated in the entire bottom area, reducing local viscosity changes caused by uneven heat, helping to reduce the burden on the main stirring paddle 210, extending the service life of the equipment, and at the same time reducing equipment wear caused by high viscosity.

[0038] It should be supplemented that the medium in the sandwich layer 122 can effectively isolate the external environment, reduce heat dissipation, and ensure the maximization of energy utilization during the heating process.

[0039] As a further implementation method, please continue to refer to Figure 4 , an input port 123 and an output port 124 are provided on the sandwich layer 122. The input port 123 and the output port 124 are respectively connected to the sandwich layer 122. The input port 123 is arranged at the bottom of the sandwich layer 122, and the output port 124 is arranged at the top of the sandwich layer 122. The input port 123 and the output port 124 can be respectively connected through pipelines, and the medium is circulated and transported into the sandwich layer 122.

[0040] This circulation mode can keep the temperature of the heating medium stable, so that the jacket body 121 can provide uniform heat, prevent local overheating or cooling, and ensure that the adhesive liquid is heated uniformly.

[0041] In some embodiments, please continue to refer to Figure 4 , the bottom of the main stirring paddle 210 is connected to the bottom of the tank body 110 through a mechanical seal structure, which can effectively prevent the leakage of the adhesive liquid or other media during the stirring process. The mechanical seal provides a highly reliable sealing effect, ensuring that the media in the mixing tank 100 will not leak out, and at the same time preventing external pollutants from entering the inside of the tank body 110.

[0042] In the specific implementation process, the mechanical seal structure can be selected such as single-end face seal, double-end face seal, spring seal, etc.

[0043] The bottom of the main stirring paddle 210 extends relative to the ground and is connected to the ground through a thrust bearing. The thrust bearing shares the weight of the stirring paddle and the axial force during operation, reduces the wear and impact on the stirring paddle and its connection parts, and thus extends the service life of the equipment.

[0044] The main stirring paddle 210 is connected to the ground through a thrust bearing, providing an additional support point. This design increases the stability of the stirring paddle, reduces the structural instability problems caused by vibrations or eccentric forces generated during the rotation process, and thus improves the overall balance and reliability of the stirring system.

[0045] In some embodiments, referring to Figures 3 to 5 , the main stirring assembly 200 further includes a driving motor 220 and a protective sleeve 230. The top of the main stirring paddle 210 passes through the top opening of the tank body 110 and is connected to the driving motor 220. The driving motor 220 is connected to the frame through a bracket. The driving motor 220 can be firmly fixed and can provide power for the rotation of the main stirring paddle 210.

[0046] The protective sleeve 230 is sleeved on the main stirring paddle 210 and is connected to the frame. The protective sleeve 230 can protect the servo motor and the transmission system, preventing dust, liquid, chemical substances or other possible contaminants from entering the interior of the motor. This achieves an extended service life and reliability, and reduces the risk of failures caused by the external environment.

[0047] At the same time, the protective sleeve 230 can also prevent operators from directly contacting rotating parts or high-temperature parts during the working process, reducing the risk of accidental injuries.

[0048] It should be supplemented that an infrared sensor is provided at the top opening of the tank body 110. The infrared sensor is electrically connected to the servo motor. When the infrared sensor is triggered due to a person or a raw material bucket falling into the tank body 110, the power supply of the servo motor can be cut off, realizing an emergency stop of the main stirring paddle 210 and ensuring the safety of personnel and equipment.

[0049] In some embodiments, referring to Figure 4 , the middle part of the auxiliary stirring paddle 310 is rotatably connected to the tank body 110. An installation hole is opened on one side of the top of the tank body 110. The auxiliary stirring paddle 310 is connected to the installation hole through a bearing. The auxiliary stirring paddle 310 can rotate relative to the tank body 110 under the drive of the outside world to stir the glue liquid and avoid the glue liquid sticking to the inner wall of the tank body 110.

[0050] One end of the auxiliary stirring paddle 310 extends relatively into the interior of the tank body 110. Both the auxiliary stirring paddle 310 and the main stirring paddle 210 are located inside the tank body 110. The two are arranged at a relative interval and can move relatively independently. The auxiliary stirring paddle 310 and the main stirring paddle 210 can rotate independently to complete the corresponding stirring functions. They can also rotate simultaneously to provide an additional stirring and flowing effect, enhancing the overall stirring effect and improving the uniformity and quality of the glue liquid.

[0051] During use, when the main stirring paddle 210 continuously stirs the glue liquid until it is completely formed, the main stirring paddle 210 can be powered off and stopped. Only the auxiliary stirring paddle 310 needs to be started and the auxiliary stirring paddle 310 is kept rotating intermittently, which can prevent the sedimentation of the glue liquid, and can also promote the rapid flow of the glue liquid near the inner wall of the tank body 110, avoiding the adhesion of the glue liquid to the inner wall of the tank body 110. The setting of the auxiliary stirring paddle 310 can shorten the working duration of the main stirring paddle 210 and reduce the wear of the main stirring paddle 210.

[0052] In some embodiments, please refer to Figure 3 and Figure 4 , the tank body 110 further includes an openable and closable discharge port 130, and the discharge port 130 can discharge the glue liquid located in the tank body 110. The discharge port 130 is arranged at the bottom of the tank body 110 and is offset relative to the main stirring paddle 210. The offset setting of the discharge port 130 can prevent the glue liquid from interfering with the main stirring paddle 210 during the discharge process, thereby improving the operation safety. It can also prevent the staff from directly contacting the stirring paddle during the operation, effectively reducing the risk of accidents.

[0053] In some embodiments, please refer to Figure 1 and Figure 2 , the glue raw material stirring device for wood substrate sheets further includes a workbench 400. The workbench 400 is arranged around the tank body 110, and a working space adapted to the top opening of the tank body 110 is provided at the top of the workbench 400, so as to facilitate the operations of workers such as feeding, sampling, and adjusting equipment, improving the work efficiency and comfort.

[0054] In the specific implementation process, a platform is provided at the top of the workbench 400, and the height of the platform is adapted to the top opening of the tank body 110, so as to facilitate the operation of workers. A step ladder is provided on one side of the platform, and workers can use the step ladder to get on and off the platform.

[0055] In some embodiments, please refer to Figure 1 and Figure 6 , the glue raw material stirring device for wood substrate sheets further includes a powder adding component 500. The powder adding component 500 includes a material accumulating hopper 510 for storing powder and a screw conveyor 520. The two ends of the screw conveyor 520 are respectively connected to the material accumulating hopper 510 and the tank body 110. The screw conveyor 520 enables the powder to be accurately conveyed into the mixing tank 100, and the raw material of the powder in the tank body 110 can be accurately controlled, avoiding the problems of too much or too little that may occur during manual addition, ensuring the accuracy of the powder ratio in each production, and thus ensuring the quality consistency of the final product.

[0056] The screw conveyor 520 is a closed system that can effectively prevent the leakage of powder into the air during transportation, reducing dust pollution. It improves the cleanliness of the operating environment and helps to maintain a healthy and safe working environment.

[0057] The above is only a preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any changes or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed by the present invention should be covered by the present invention.
