Description
Technical Field
[0001] This utility model relates to the field of decorative paper production technology, and in particular to a stirring device for decorative paper production. Background Technology
[0002] Decorative paper (also known as impregnated paper) is a type of paper that has undergone a special process and is commonly used for the decoration and protection of surfaces such as furniture, flooring, and walls. It consists of a paper base and impregnating resin. Through the resin impregnation process, it acquires properties such as abrasion resistance, high-temperature resistance, and moisture resistance. Decorative paper is widely used in interior decoration, building materials, furniture, flooring, and other fields, often serving as a surface decorative layer, and is characterized by its aesthetic appeal and durability. The production process of decorative paper requires an impregnation treatment, in which the paper base is immersed in a resin-containing solution. The resin solution needs to be stirred during preparation to ensure complete dissolution and achieve the desired viscosity.
[0003] However, existing mixing devices for decorative paper production only use one mixing method, such as mechanical mixing or gas mixing, and the mixing direction is always in one direction, resulting in poor mixing effect and uneven distribution of resin solution, which affects the final impregnation quality of decorative paper. Utility Model Content
[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a stirring device for decorative paper production.
[0005] To achieve the above objectives, the present invention adopts the following technical solution:
[0006] A mixing device for decorative paper production includes: a mixing box, a mixing shaft vertically penetrating and rotatably connected to the center of the top of the mixing box, mixing blades welded to the outer periphery of the mixing shaft inside the mixing box, a sleeve sleeved around the outer periphery of the mixing shaft, the sleeve penetrating the top of the mixing box and rotatably connected to the mixing box, four connecting pipes horizontally and evenly connected below the outer periphery of the sleeve, and the other end of the four connecting pipes connected to the same annular pipe, the bottom of the annular pipe connected to an L-shaped air outlet pipe;
[0007] The drive mechanism is used to drive the stirring shaft and the sleeve to rotate;
[0008] An air supply mechanism is used to supply air to the sleeve.
[0009] As a further technical solution of this utility model, three support legs are evenly welded to the bottom edge of the mixing tank, a controller is fixedly installed on one side of the outside of the mixing tank, a feeding port is opened on one side of the top of the mixing tank, and a top cover is provided on the top of the feeding port.
[0010] As a further technical solution of this utility model, a discharge port is provided at the center of the bottom of the mixing tank, and a discharge valve is installed on the discharge port. A vent pipe is vertically connected to one side of the top of the mixing tank, and a vent valve is installed on the vent pipe.
[0011] As a further technical solution of this utility model, the stirring blades are provided in multiples and are evenly distributed along the circumference and vertically on the outer periphery of the stirring shaft located inside the stirring box. The stirring shaft and the sleeve are rotatably connected, and the sleeve is hollow inside and has an open top structure.
[0012] As a further technical solution of this utility model, multiple L-shaped air outlet pipes are provided and evenly distributed along the circumference at the bottom of the annular pipe. The bottom end of the L-shaped air outlet pipe faces inward and is located at the bottom of the mixing tank. A waterproof and breathable membrane is installed at the bottom end of the L-shaped air outlet pipe.
[0013] As a further technical solution of this utility model, the driving mechanism includes a rotary motor, an F-type mounting bracket welded to the top of the mixing tank, the rotary motor being horizontally fixedly mounted inside the F-type mounting bracket, a driving bevel gear being fixedly mounted at the output end of the rotary motor, a first driven bevel gear welded to the outer periphery of the sleeve, and a second driven bevel gear welded to the outer periphery of the stirring shaft. The first and second driven bevel gears are symmetrically arranged, and both the first and second driven bevel gears mesh with the driving bevel gear. The sleeve passes through the F-type mounting bracket and is rotatably connected to the F-type mounting bracket, and the top end of the stirring shaft is rotatably connected to the bottom of the F-type mounting bracket.
[0014] The rotating motor is started, which drives the active bevel gear to rotate. The active bevel gear drives the sleeve to rotate forward through the first driven bevel gear, and drives the stirring shaft to rotate in the opposite direction through the second driven bevel gear. The sleeve drives the annular tube to rotate forward through the connecting pipe, and the annular tube drives multiple L-shaped air outlet pipes to rotate in the forward direction, thereby stirring the resin on the outer side of the mixing box in the forward direction. The stirring shaft drives multiple stirring blades to rotate in the opposite direction, thereby stirring the resin on the inner side of the mixing box in the reverse direction. The two stirring directions work together to enhance the stirring effect, making the resin solution more evenly distributed and ensuring the final impregnation quality of the decorative paper.
[0015] As a further technical solution of this utility model, the air supply mechanism includes a hot air blower, which is fixedly installed on one side of the top of the mixing tank. The air outlet of the hot air blower is connected to an L-shaped air supply pipe. The other end of the L-shaped air supply pipe is connected to and rotatably connected to the top of the sleeve. The mixing shaft passes through the L-shaped air supply pipe and is rotatably connected to the L-shaped air supply pipe.
[0016] The hot air generated by the hot air blower is directed to the sleeve through an L-shaped air supply pipe, then to the annular pipe through four connecting pipes, and finally sprayed into the resin at the bottom of the mixing tank through multiple L-shaped air outlet pipes. As the L-shaped air outlet pipes continuously revolve, the hot air sprayed from the bottom of the L-shaped air outlet pipes forms a spiral airflow that also stirs the resin. The combination of mechanical and gas stirring enhances the stirring effect, making the resin solution more evenly distributed and ensuring the final impregnation quality of the decorative paper. In addition, the hot air entering the resin can also heat the resin, accelerating its dissolution and increasing its fluidity.
[0017] The beneficial effects of this invention are as follows: it combines mechanical stirring and gas stirring, and the two stirring directions cooperate with each other, which enhances the stirring effect, makes the resin solution more evenly distributed, and ensures the final impregnation quality of the decorative paper; in addition, the hot air entering the resin can also heat the resin, accelerate the dissolution of the resin, and increase the fluidity of the resin.
