Description

Technical Field

[0001] This utility model relates to the field of papermaking raw material technology, specifically to a pulp ratio adjustment mechanism for corrugated paper production. Background Technology

[0002] Corrugated paper consists of three layers: an outer paper layer, an inner paper layer, and a corrugated core board. The outer and inner paper layers are bonded to the inner and outer sides of the corrugated core board using adhesives to create corrugated paper. The production of the outer paper layer, inner paper layer, and corrugated core board all require main fiber pulp and other fiber pulps. For example, in the production of the outer paper layer, the main fiber pulp and other fiber pulps are added to a mixer in a specific ratio and mixed to obtain the outer fiber pulp. This pulp is then used in a papermaking machine to form the outer paper layer. Currently, the mixing of main fiber pulp and other fiber pulps is mostly done manually. Manual mixing allows for estimation of the raw materials, leading to uneven fiber pulp proportions and affecting the paper's strength. Utility Model Content

[0003] Based on this, the purpose of this utility model is to provide a pulp ratio adjustment mechanism for corrugated paper production, so as to solve the technical problems mentioned in the background.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a pulp proportioning adjustment mechanism for corrugated paper production, comprising a mixer and a pulp preparation tank. The mixer has inlets on both sides of its top and a discharge port at its bottom. The inlets are connected to the bottom of the pulp preparation tank via inlet pipes. The pulp preparation tank is mounted on a support and its bottom is higher than the top of the mixer. The pulp preparation tank contains a float and a level switch, and both the float and the level switch contain magnetic elements.

[0005] Furthermore, the slurry preparation tank is equipped with a fixed rod, the float is sleeved on the fixed rod and floats on the liquid surface, a sliding groove is fixed on the inner wall of the slurry preparation tank near the float, a slider is provided in the sliding groove, the liquid level switch is fixed on the slider, an adjusting rod is fixed above the slider, the top of the adjusting rod passes through the top of the slurry preparation tank, and a fixing block for fixing the adjusting rod is provided on the top of the bagasse slurry preparation tank.

[0006] Furthermore, the slurry preparation tank has a feed inlet on one side of its top, which is connected to a submersible pump installed in the slurry tank via a pipe, and the liquid level switch is electrically connected to the submersible pump.

[0007] Furthermore, a solenoid valve is provided at the outlet of the slurry preparation box.

[0008] In summary, the present invention has the following main advantages:

[0009] This invention uses an internal float and level switch to control the submersible pump to disconnect, ensuring precise mixing of the pulp extracted into the tank. This saves labor costs, improves work efficiency, and enhances the strength of the paper stock. Furthermore, the bottom of the pulp preparation tank is higher than the top of the mixer. After the mixed pulp in the mixer has been discharged from the discharge port, simply opening the solenoid valve at the bottom outlet of the pulp preparation tank allows all the remaining pulp to be discharged into the mixer for immediate mixing, further improving work efficiency. Attached Figure Description

[0010] Figure 1 This is a schematic diagram of the structure of this utility model;

[0011] Figure 2 This is a schematic diagram of the internal structure of the material preparation box of this utility model. Detailed Implementation

[0012] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0013] The embodiments of this utility model will be described below based on its overall structure.

[0014] like Figure 1 As shown, this utility model includes a mixer 1 and a slurry preparation tank 2. The mixer 1 has inlets 11 on both sides of its top and a discharge port 12 at its bottom. The inlets 11 are connected to the bottom of the slurry preparation tank 2 via inlet pipes 4. This utility model has two slurry preparation tanks 2, each connected to an inlet 11 via inlet pipes 4. Since the two slurry preparation tanks 2 have the same structure and function, only one is shown in this application. The specific internal structure and working principle of the mixer 1 are existing technology and common technical knowledge, therefore they will not be described further in this application. The slurry preparation tank 2 is mounted on a bracket 3 with its bottom higher than the top of the mixer 1. A solenoid valve 6 is provided at the discharge port of the slurry preparation tank 2. By setting the slurry preparation tank 2 higher than the mixer 1, when it is necessary to add material to the mixer 1, only the solenoid valve 6 needs to be opened, without any external force.

[0015] like Figure 2As shown, the pulp preparation tank 2 is equipped with a float ball 21 and a level switch 22. A fixed rod 23 is also provided inside the pulp preparation tank 2. The float ball 21 is fitted onto the fixed rod 23 and floats on the liquid surface. A groove 24 is fixed to the inner wall of the pulp preparation tank 2 near the float ball 21. A slider 25 is installed inside the groove 24. The level switch 22 is fixed to the slider 24. An adjusting rod 26 is fixed above the slider 25. The top of the adjusting rod 26 passes through the top of the pulp preparation tank 2. The bagasse pulp preparation tank... The top of the material tank 2 is equipped with a fixing block 27 for fixing the adjusting rod 26. When it is necessary to adjust the height of the liquid level switch 22, loosen the bolt 28 on the fixing block 27 to allow the adjusting rod 26 to move up and down. The adjusting rod 26 drives the liquid level switch 22 fixed on the slider 25 to move up and down. After adjusting to the appropriate height, tighten the bolt 28. The top side of the pulp preparation tank 2 is equipped with a feed inlet, which is connected to the submersible pump 5 installed in the bagasse pulp tank 4 through a pipe. Both the float 21 and the level switch 22 are equipped with magnetic elements. When slurry is pumped into the slurry preparation tank 2, the float 21, which floats on the surface of the slurry, rises with the rise of the liquid level. When it approaches or is level with the level switch 22, the magnetic element inside the float 21 triggers the magnetic element inside the level switch 22, causing the level switch 22 to send a power-off signal to the submersible pump, stopping the pumping of slurry into the slurry preparation tank 2, thus achieving accurate metering. The float 21, level switch 22, and the level switch 22 controlling the submersible pump 5 in this application all adopt existing technologies and can be purchased and installed on the market.

[0016] Although embodiments of the present invention have been shown and described, these specific embodiments are merely explanations of the present invention and are not intended to limit the invention. The specific features, structures, materials, or characteristics described may be combined in any suitable manner in one or more embodiments or examples. After reading this specification, those skilled in the art may make modifications, substitutions, and variations to the embodiments as needed without departing from the principles and spirit of the present invention, provided that such modifications, substitutions, and variations are within the scope of the claims of the present invention and are protected by patent law.
