Description

Technical Field

[0001] This utility model relates to the field of decorative paper production technology, and in particular to a pulp treatment device for decorative paper production. Background Technology

[0002] Decorative paper is an essential raw material in many building materials products, such as low-pressure boards and high-pressure boards used in furniture and cabinets, as well as fireproof boards and flooring. Decorative paper requires high toughness during processing. This toughness depends not only on the strength of the raw fiber but also on its length. Currently, the pulverized raw material is mixed evenly with water to produce a pulp. However, this mixing process currently uses a stirring rod. Because the stirring rod is rigid, it easily breaks long fibers in the raw material during mixing, directly reducing the toughness of the finished decorative paper. Therefore, a pulp treatment device for decorative paper production is needed to meet this requirement. Utility Model Content

[0003] The purpose of this invention is to address the shortcomings of existing technologies where long fibers in raw materials are easily broken during pulp mixing, and to propose a pulp processing device for decorative paper production.

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

[0005] Design a pulp treatment device for decorative paper production, including a mixing tank. Multiple protective covers are fixed on the outer bottom wall of the mixing tank. An airbag column is connected and sealed to the bottom wall of the mixing tank inside each protective cover. An air guide pipe is connected and fixed to each protective cover. A diversion pipe is fixed to the multiple air guide pipes. An air exchange pipe is connected and fixed to the diversion pipe.

[0006] Preferably, the mixing box is provided with an auxiliary tilting mechanism.

[0007] Preferably, the auxiliary tilting mechanism includes a fixed frame, on which two support rods are fixed. Both support rods are rotatably mounted on the outer bottom wall of the mixing tank. A pulling mechanism is fixed to the mixing tank and the fixed frame.

[0008] Preferably, the pulling mechanism includes two connecting ropes, both of which are fixed to the mixing box, and a winding mechanism is fixed together on the two connecting ropes and the fixing frame.

[0009] Preferably, the winding mechanism includes a motor, which is fixed on the fixed frame. A rotating shaft is fixed on the output shaft of the motor, and the rotating shaft is rotatably mounted on the fixed frame and fixed to the two connecting ropes.

[0010] Preferably, a limiting rod is slidably provided on both of the connecting ropes, and the limiting rod is fixed on the fixing frame.

[0011] Preferably, a plurality of fixed columns are fixed on the fixed frame on one side of the rotating shaft, and a guide roller is fixed on the plurality of fixed columns together, the guide roller being inserted inside the mixing box.

[0012] The present invention discloses a pulp treatment device for decorative paper production, which has the following advantages: During use, the device utilizes changes in air pressure within multiple protective covers to allow multiple airbag columns to move in and out of the covers. The airbag columns extruded from the covers insert into the pulp in the mixing chamber. When the airbag columns return to the covers, the pulp in the mixing chamber enters the airbag columns within the covers, thus mixing the pulp. Furthermore, the airbag columns are flexible, ensuring that long fibers in the pulp are not broken during mixing, thereby ensuring the toughness of the decorative paper produced after subsequent processing.

[0020] 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.

[0021] Example 1

[0022] Reference Figure 1 , 2 3, 5, and 6, a pulp treatment device for decorative paper production, comprising a mixing tank 1, with multiple protective covers 3 fixed on the outer bottom wall of the mixing tank 1. Each protective cover 3 has an airbag column 2 connected and sealed to the bottom wall of the mixing tank 1. When the airbag column 2 is adsorbed into the protective cover 3, the airbag column 2 adheres to the inner side wall of the protective cover 3, and the shape of the airbag column 2 and the protective cover 3 matches, so that the protective cover 3 supports and protects the airbag column 2. Each protective cover 3 is connected and fixed with an air guide pipe 4, and multiple air guide pipes 4 are connected and fixed with a diversion pipe 5. The diversion pipe 5 is connected and fixed with an air exchange pipe 6, and an air pump is fixed on the air exchange pipe 6. The air pump is used to inflate and draw air, thereby regulating the air pressure inside the multiple protective covers 3.

[0023] During use, an air pump is used to alternately inflate and de-inflate multiple protective covers 3 through an air exchange pipe 6, a diversion pipe 5, and multiple air guide pipes 4. When multiple protective covers 3 are inflated, multiple airbag columns 2 in multiple protective covers 3 are pushed out and inserted into the slurry in the mixing box 1. When multiple protective covers 3 are de-inflated, multiple airbag columns 2 are sucked back into multiple protective covers 3, and the slurry in the mixing box 1 enters the multiple airbag columns 2 in multiple protective covers 3. In this process, the slurry in the mixing box 1 is mixed. Since multiple airbag columns 2 are soft, during the mixing process, it can ensure that the long fibers in the slurry will not be broken, thereby ensuring the toughness of the decorative paper produced by the subsequent processing of the slurry.

[0024] Example 2

[0025] In Example 1, although multiple airbag columns 2 can mix the slurry in the mixing tank 1, the bottom of the slurry in the mixing tank 1 plays a major role in mixing, resulting in a long mixing time. (Refer to...) Figure 1 , 23, 4 and 6, as another preferred embodiment of this utility model, differ from embodiment 1 in that the mixing box 1 is provided with an auxiliary tilting mechanism. The auxiliary tilting mechanism includes a fixed frame 8, on which two support rods 7 are fixed. Both support rods 7 are rotatably mounted on the outer bottom wall of the mixing box 1. A pulling mechanism is fixed on the mixing box 1 and the fixed frame 8. The pulling mechanism can pull the mixing box 1 to shake, thereby accelerating the mixing of the slurry in the mixing box 1.

[0026] The pulling mechanism includes two connecting ropes 13, both of which are fixed to the mixing box 1. A winding mechanism is fixed to both connecting ropes 13 and the fixed frame 8. The winding mechanism is used to wind and unwind the two connecting ropes 13. In addition, the rotating connection between the mixing box 1 and the two support rods 7 can drive the mixing box 1 to shake. The winding mechanism includes a motor 14, which is fixed to the fixed frame 8. A rotating shaft 11 is fixed to the output shaft of the motor 14. The rotating shaft 11 is rotatably mounted on the fixed frame 8 and is fixed to the two connecting ropes 13.

[0027] Limiting rods 12 are slidably mounted on both connecting ropes 13. The limiting rods 12 are fixed on the fixed frame 8. Multiple fixed columns 9 are fixed on the fixed frame 8 on one side of the rotating shaft 11. Guide rollers 10 are fixed on the multiple fixed columns 9. The guide rollers 10 are inserted inside the mixing box 1. When the mixing box 1 shakes, the position of the guide rollers 10 remains unchanged. Thus, the guide rollers 10 can mix the upper layer of slurry in the mixing box 1. In addition, the contact surface between the guide rollers 10 and the slurry is an arc surface, and the movement is gentle. Therefore, while mixing the upper layer of slurry in the mixing box 1, the long fibers in the slurry will not be damaged.

[0028] When in use, the motor 14 is started when multiple airbag columns 2 mix the lower layer of slurry in the mixing box 1. The motor 14 rotates the shaft 11 to retract and release the two connecting ropes 13. During the retraction and release process, the mixing box 1 shakes under the support of the two support rods 7. When the mixing box 1 shakes, it not only accelerates the mixing of the slurry in the mixing box 1, but also allows the guide roller 10 to come into contact with more of the upper layer of slurry inside the mixing box 1, thereby accelerating the mixing of the slurry in the mixing box 1.

[0029] 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.
