Description

Technical Field

[0001] This utility model relates to the field of paper impregnation technology, and in particular to a device for adding impregnation adhesive to impregnated paper. Background Technology

[0002] In recent years, with the rapid development of my country's wood-based panel industry, impregnated paper veneer panels have become widely used due to their relatively low price, wide variety of colors and patterns, and good physical and mechanical properties. They are often used in conjunction with plywood to replace solid wood in the production of furniture and flooring.

[0003] Impregnation is the core part of impregnated paper production, typically using formulated urea-formaldehyde resin and melamine, either alone or in combination. However, it's important to note that in existing impregnation equipment, the liquid level in the impregnation tank decreases during the impregnation process, necessitating replenishment. Current methods for replenishing the impregnation liquid generally involve directly adding melamine to the impregnation tank, or manually or mechanically mixing the urea-formaldehyde resin and melamine before adding it to the tank. However, these methods have the following drawbacks:

[0004] 1. Existing impregnation equipment or impregnation tanks have a simple structure, usually a square cavity or tank. The impregnation liquid flows in from one side of the impregnation tank. Since the liquid inside the tank does not circulate, the liquid concentration of the impregnation liquid on the side near the impregnation liquid inlet is higher than that on the side away from the impregnation liquid inlet. This makes it easy for the impregnated paper to be impregnated unevenly.

[0005] 2. When the impregnated paper enters the impregnation tank for impregnation, contaminants such as debris on the surface of the impregnated paper will remain in the impregnation tank, causing contamination of the impregnation solution and affecting the impregnation effect of the impregnated paper.

[0006] Therefore, designing a paper impregnation adhesive feeding device that can solve the above-mentioned technical problems is a technical issue that needs to be addressed. Utility Model Content

[0007] In order to solve the above problems, the purpose of this utility model is to provide an impregnation adhesive feeding device for impregnated paper, so as to solve the problems of impregnation liquid not circulating in the impregnation tank after the existing impregnation liquid is added, and the different impregnation liquid concentrations affecting the impregnation effect.

[0008] To achieve the above objectives, the present invention adopts the following technical solution: including a chassis, a recovery liquid inlet pipe connected to one side of the chassis, a first inlet pipe and a second inlet pipe connected to the top of the chassis, a stirring device installed on the chassis, a power filtration device fixed inside the chassis, and a spraying device connected to the bottom of the chassis.

The impregnation liquid is filtered by a filter element to remove contaminants such as paper scraps. The filtered impregnation liquid enters the mixing chamber through an overflow hole. The first stirring component in the filtration chamber stirs the impregnation liquid in the filtration chamber to prevent sedimentation of the glue at the bottom. The second stirring component in the mixing chamber mixes the filtered impregnation liquid, the newly added urea-formaldehyde resin and melamine.

[0017] 2- This utility model changes the flow direction of the impregnation liquid by using an electric push rod, so that the mixed impregnation liquid in the mixing chamber is injected into the impregnation tank through the liquid outlet pipe before impregnation, and is evenly sprayed into the impregnation tank through the nozzle during impregnation, thereby improving the impregnation effect of the impregnated paper.

[0035] The spraying device 7 includes a liquid inlet hopper 71 connected to the mixing chamber 13, a solenoid valve 72 connected to the liquid outlet of the liquid inlet hopper 71 for controlling liquid flow, a flow conversion assembly 73 connected to the liquid outlet of the solenoid valve 72, a spraying assembly 74 connected to the flow conversion assembly 73, and a liquid outlet pipe 75 connected to the flow conversion assembly 73. The flow conversion assembly 73 includes a connecting body 731 and an electric push rod 732 movably passing through one side of the connecting body 731. A first liquid inlet channel 7311 is formed on the upper surface of the connecting body 731 along the vertical direction of the connecting body 731, and a second liquid inlet channel 7312 is formed on the side wall of the connecting body 731 along the horizontal direction of the connecting body 731. Liquid channel 7312; the lower end face of the connector 731 is provided with a third liquid inlet channel 7313 along the vertical direction of the connector 731, and the second liquid inlet channel 7312 extends in the opposite direction and is connected to the third liquid inlet channel 7313; the liquid spraying assembly 74 includes a liquid spraying box 741, a plurality of nozzles 742 fixed on the lower end face of the liquid spraying box 741, a second connecting water pipe 743 arranged in the liquid spraying box 741 and connected to the plurality of nozzles 742, and a third connecting water pipe 744 connecting the second water pipe and the second liquid inlet channel 7312; the liquid outlet pipe 75 is connected to the third liquid inlet channel 7313; the movable end of the electric push rod 732 is provided with a stop block 7321 for adjusting the liquid flow direction.

[0036] Furthermore, a door 14 is hinged to the housing 1 at a position corresponding to the filter compartment 62. Even further, a sealed door is hinged to the side of the filter compartment 62 opposite to the door 14. This facilitates regular replacement of the filter element 63 by the user.

[0037] Furthermore, the outer diameter of the stop 7321 is the same as the inner diameter of the second liquid inlet channel 7312, and the outer diameter of the electric push rod 732 is smaller than the inner diameter of the second liquid inlet channel 7312.

[0038] The working principle is roughly as follows:

[0039] The water pump 61 is used to pump the impregnation liquid in the impregnation tank into the filter chamber 12 inside the machine box 1 through the recovery liquid inlet pipe 2, and then into the filter chamber 62 through the first connecting water pipe 64 to filter the impregnation liquid; when the impregnation liquid enters the filter chamber 12 through the filter chamber 62 and enters the mixing chamber 13 through the overflow hole 111, the urea-formaldehyde resin and melamine or other impregnation liquid are mixed at the same time through the first inlet pipe 3 and the second inlet pipe 4.

[0040] In the initial state, when the impregnation solution is injected into the impregnation tank, such as Figure 2-3 As shown, the electric push rod 732 is pushed inward, causing the movable end block 7321 of the electric push rod 732 to move to the junction of the second liquid inlet channel 7312 and the first liquid inlet channel 7311, blocking the second liquid inlet channel 7312. This allows the impregnation liquid to pass through the solenoid valve 72 and flow from the first liquid inlet channel 7311, part of the second liquid inlet channel 7312, the third liquid inlet channel 7313, and into the outlet pipe 75. The liquid then flows from the storage end of the outlet pipe 75 into the impregnation tank, thereby injecting the impregnation liquid into the impregnation tank.

[0041] During the impregnation process of impregnated paper, when injecting the impregnation solution into the impregnation tank, such as Figure 4-5 As shown, the electric push rod 732 is extended outward, causing the stop block 7321 at the movable end of the electric push rod 732 to move to the junction of the second liquid inlet channel 7312 and the third liquid inlet channel 7313. This allows the impregnation liquid to pass through the solenoid valve 72 and flow from the first liquid inlet channel 7311, part of the second liquid inlet channel 7312, into the second connecting water pipe 743 and the third connecting water pipe 744, and then be evenly sprayed out from several nozzles 742.

Any equivalent structural transformations made based on the contents of this utility model specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
