Technical Field
[0001] The utility model belongs to the technical field of dilution, in particular to a filler dilution device for polyurethane resin production. Background Art
[0002] Polyurethane resin is a polymer made of isocyanate (monomer) and hydroxyl compound. It is known as the "fifth largest plastic" and is widely used in many fields of the national economy due to its excellent performance, such as surface finishing of wooden furniture and metal, thermal insulation, thermal insulation and waterproofing of house buildings, etc. When producing polyurethane resin, in order to reduce the viscosity and solid content of polyurethane resin, thereby improving its operability during production and use, making it have better fluidity, and can be better coated on the required surface, improving production efficiency and quality, it is often diluted during the mixing operation;
[0003] At present, most of the existing polyurethane resin dilution methods are directly through manual feeding of materials. In addition to the high labor cost, the manual feeding method is also prone to errors, which affects the production quality and is difficult to ensure work efficiency.
[0004] In order to solve the above problems, the present application proposes a filler dilution device for polyurethane resin production. Utility Model Content
[0005] The purpose of the utility model is to provide a filler dilution device for polyurethane resin production, which solves the problems raised in the above background technology.
[0006] In order to solve the above technical problems, the utility model is realized by the following technical solutions:
[0007] The utility model discloses a filler dilution device for producing polyurethane resin, comprising: a stirring tank and a top cover at its upper end; a filler tank is arranged on one side of the upper end of the top cover, a feeding pipe for feeding filler is arranged on one side of the filler tank, a lower hopper for docking with the feeding pipe is arranged on the upper end of one side of the top cover, an extension pipe for docking with the lower hopper and applying filler to different height positions inside the stirring tank to promote dilution is arranged on the lower end of one side of the top cover; an inner rotating shaft is arranged inside the extension pipe, a sealing block for driving the filler to overflow is arranged on the outer side of the inner rotating shaft, a side groove is opened on one side of the extension pipe, and the sealing block is also used to seal the side groove to prevent the filler from leaking in advance.
[0008] Furthermore, the upper end of the top cover is also provided with an upper rotating shaft that drives the extension tube to rotate and control the filling state. The lower end of the upper rotating shaft is rotatably installed inside the shaft seat at the upper end of the top cover, and the shaft seat is located on the side of the filling tank adjacent to the outer side of the lower hopper.
[0009] Furthermore, a sealing box is provided inside the lower hopper to prevent fillers from entering the interior and clogging the gaps.
[0010] Furthermore, a toothed belt is provided inside the sealing box for transmitting the rotational power of the upper rotating shaft to the inner rotating shaft.
[0011] Furthermore, a transition portion meshingly connected to the toothed belt is provided on the outer side of the upper end of the inner rotating shaft.
[0012] Furthermore, the lower end of the lower hopper is provided with an inner support ring that connects to the extension pipe to prevent the filler from escaping outwards.
[0013] Furthermore, two side surfaces of the sealing block form an angle to confine the filler inside for easy subsequent application and use.
[0014] The utility model has the following beneficial effects:
[0015] The utility model can add an extension pipe under the top cover, and then the filler can be directly put into the extension pipe after being applied to the inside of the lower hopper by the feeding pipe for subsequent delivery. This process can directly replace manual labor, achieve efficient delivery operation, avoid errors and ensure product production quality.
[0016] After the utility model stores the filler to be put in through the extension tube, the upper rotating shaft can be used to drive the sealing block to rotate to release the blockage of the opposite side groove. At this time, the filler can be directly applied to the inside of the mixing tank and dispersed at different height positions of the mixing tank to promote mixing efficiency. While improving the dilution efficiency, it effectively avoids the situation where the top is put in but the dilution effect cannot be fully exerted.
[0017] Of course, any product implementing the present invention does not necessarily need to achieve all of the advantages described above at the same time. BRIEF DESCRIPTION OF THE DRAWINGS

[0027] See also Figure 1-4 As shown, the utility model is a filler dilution device for polyurethane resin production, comprising: a stirring tank 1 and a top cover 2 at its upper end;
[0028] A filling tank 3 is arranged on one side of the upper end of the top cover 2, a feeding pipe 5 for feeding the filling is arranged on one side of the filling tank 3, a lower hopper 4 docking with the feeding pipe 5 is arranged on the upper end of one side of the top cover 2, and an extension pipe 6 docking with the lower hopper 4 to apply the filling to different height positions inside the mixing tank 1 to promote dilution is arranged on the lower end of one side of the top cover 2;
[0029] An inner rotating shaft 7 is arranged inside the extension tube 6, and a sealing block 8 is arranged outside the inner rotating shaft 7 to drive the filler to overflow. A side groove 9 is opened on one side of the extension tube 6, and the sealing block 8 is also used to seal the side groove 9 to prevent the filler from leaking in advance;
[0030] This embodiment provides a dilution filler delivery mechanism during polyurethane resin production, which uses an extension tube 6 to penetrate into the interior of the mixing tank 1. When delivering the filler, it can be directly delivered to different height positions inside the mixing tank 1 to increase the contact area between the filler and the raw material and improve the dilution efficiency.
[0031] Among them, the upper end of the top cover 2 is also provided with an upper rotating shaft 10 which drives the extension tube 6 to rotate and control the filling state. The lower end of the upper rotating shaft 10 is rotatably installed inside the shaft seat 13 at the upper end of the top cover 2. The shaft seat 13 is located on the side of the filling tank 3 adjacent to the outer side of the lower hopper 4. The upper end of the upper rotating shaft 10 is a wheel mechanism, and the rotation angle can also be controlled by adding a rotating motor.
[0032] A sealing box 11 is provided inside the lower hopper 4 to prevent fillers from entering the interior and clogging the gaps, thereby ensuring the operational stability of the internal mechanism.
[0033] A toothed belt 12 is disposed inside the sealing box 11 to transmit the rotational power of the upper rotating shaft 10 to the inner rotating shaft 7 .

[0036] The two side surfaces of the sealing block 8 form an angle to limit the filler inside for easy subsequent application and use.
[0037] It is understandable that the utility model can directly apply the dilution filler to various height positions inside the equipment without manual placement, so as to accelerate its dilution efficiency and avoid excessive filler accumulation at the upper position affecting the dilution efficiency.
[0038] A specific application of the operation process of this embodiment is as follows: when in use, the filler is first transported to the interior of the lower hopper 4 through the feed pipe 5, and then the seasoning is automatically stored on one side of the extension tube 6, and is confined in a certain area by the two side surfaces of the sealing block 8, and then the upper rotating shaft 10 is rotated to drive the inner rotating shaft 7 to rotate via the toothed belt 12. At this time, the sealing block 8 rotates to push the filler and release the blockage of the side groove 9, and then the filler is automatically applied to different height positions inside the mixing tank 1 to increase the contact area with the raw materials and promote dilution, so as to improve the production efficiency and dilution quality of the polyurethane resin.
