Description

Technical Field

[0001] This utility model relates to the field of polyurethane compound processing technology, and in particular to an automatic material discharge system. Background Technology

[0002] Polyurethane composite materials are an important industrial product with excellent thermal insulation, waterproofing, and flame retardant properties, and are widely used in construction, industry, and transportation. In the production and processing of polyurethane composite materials, automated feeding systems are often used to automatically discharge the materials for subsequent molding processes. This significantly reduces manual operation time and labor intensity, enabling rapid and continuous material discharge, improving production efficiency, and enhancing product quality.

[0003] Existing Chinese patents, such as CN 215137314 U, disclose an automatic discharge and separation device for polyurethane resin, which achieves automatic discharge and automatic cleaning of debris on the filter screen. However, during the feeding process, the polyurethane material tends to concentrate in the middle of the filter screen. It only flows to the sides of the filter screen for filtration as the amount of polyurethane material increases, resulting in poor filtration efficiency and easy clogging of the filter screen. This affects the discharge efficiency of the discharge system and is detrimental to the subsequent processing of the polyurethane material. Utility Model Content

[0004] This invention proposes an automatic discharge system to solve the problems of poor filtration effect of polyurethane materials in existing discharge systems and easy clogging of the filter screen.

[0005] To achieve the above objectives, the present invention provides the following technical solution: an automatic material discharge system, comprising a storage box with a sealed door hinged to the front, a feeding hopper installed on the top of the storage box, a discharge pipe connected to the bottom, and a filter screen installed inside the storage box, and a liquid distribution component installed inside the storage box.

[0006] The liquid distribution assembly includes a distribution plate, a fixing rod is installed between the bottom of the distribution plate and the inner wall of the storage tank, and the distribution plate is directly above the filter screen. The top of the distribution plate has multiple through first discharge holes, and the outer wall of the distribution plate has multiple through second discharge holes.

[0007] Preferably, the outer wall of the diversion plate is provided with multiple diversion grooves, and the top of each diversion groove extends to the upper end face of the diversion plate, and the bottom of each groove is connected to multiple second discharge holes.

[0008] Preferably, the storage box is further provided with a cleaning component for cleaning the filter screen, and the cleaning component includes a fixed box installed on one side of the storage box and a mounting plate on the top of the filter screen. A movable plate is provided on one side of the mounting plate, and a cleaning brush that contacts the top of the filter screen is installed at the bottom of the movable plate. An electric telescopic rod is installed on one side of the fixed box, and the telescopic end of the electric telescopic rod extends into the interior of the storage box and is fixedly connected to one side of the mounting plate. A waste discharge pipe for discharging waste from the filter screen is also connected to the side of the storage box away from the fixed box.

[0009] Preferably, two snap-fit ​​blocks are installed on one side of the movable plate, and a snap-fit ​​groove is provided on the mounting plate for the two snap-fit ​​blocks to snap into each other. A handle is also fixed on the side of the movable plate away from the mounting plate.

[0010] Preferably, a sealing ring is also installed on the side of the mounting plate away from the moving plate, and a sealing groove that mates with the sealing ring is provided on the inner wall of the storage box.

[0011] Preferably, a downwardly inclined baffle is also installed on the inner wall of the storage box, and the baffle is positioned above the movable plate and the mounting plate.

[0012] The technical effects and advantages provided by this utility model in the above technical solution are as follows:

[0013] (1) By setting up the diversion and distribution component, when feeding, a portion of the polyurethane mixture falls onto the filter screen through the first discharge hole, a portion of the polyurethane mixture flows along the outer wall of the diversion plate and falls onto the filter screen through the second discharge hole, and the remaining portion of the polyurethane mixture is scattered along the edge of the bottom of the diversion plate and falls onto the filter screen. This achieves diversion of the polyurethane mixture, so that the polyurethane mixture falls evenly onto the filter screen, thereby facilitating the uniform filtration of the polyurethane mixture. This not only improves the filtration effect of the polyurethane mixture, but also avoids a large amount of polyurethane mixture accumulating on the filter screen, which would cause the filter screen to become clogged. This improves the filtration efficiency of the polyurethane mixture, thereby achieving high-efficiency filtration of the polyurethane mixture. This is beneficial for the rapid discharge of the discharge system and facilitates the subsequent processing of the polyurethane mixture.

[0014] (2) By setting up the snap-fit ​​block and snap-fit ​​slot, the cleaning brush can be quickly disassembled and assembled, which facilitates the regular cleaning or replacement of the cleaning brush, thus promoting the normal use of the cleaning brush and ensuring the cleaning effect of the cleaning brush on the filter screen.

Detailed Implementation

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] like Figures 1-4As shown, an automatic material discharge system includes a storage box 1 with a sealed door hinged to the front, a feeding hopper 2 installed on the top of the storage box 1, a discharge pipe 5 connected to the bottom, a filter screen 6 installed inside the storage box 1, and a liquid distribution component installed inside the storage box 1; an electric valve for easy opening and closing is installed on the discharge pipe 5.

[0026] The diversion and distribution assembly includes a diversion plate 7. A fixing rod 11 is installed between the bottom of the diversion plate 7 and the inner wall of the storage tank 1. The diversion plate 7 is located directly above the filter screen 6. The top of the diversion plate 7 has multiple through first discharge holes 8, and the outer wall of the diversion plate 7 has multiple through second discharge holes 9. The diversion plate 7 is a frustum-shaped structure with a small top diameter and a large bottom diameter.

[0027] As described above, during use, the polyurethane composite material can be added into the storage tank 1 through the feeding hopper 2. At this time, the polyurethane composite material falls onto the filter screen 6 and is filtered by the filter screen 6 before accumulating at the bottom of the storage tank 1 to remove impurities mixed in with the polyurethane composite material. When it is necessary to discharge the polyurethane composite material, the electric valve can be opened to allow the polyurethane composite material to be automatically discharged through the discharge pipe 5, so as to facilitate its feeding into the subsequent molding process and thus complete the processing of the polyurethane product.

[0028] Furthermore, when the polyurethane composite material is added into the storage tank 1, it first falls onto the distribution plate 7. At this time, a portion of the polyurethane composite material falls onto the filter screen 6 through the first discharge hole 8, another portion flows along the outer wall of the distribution plate 7 and falls onto the filter screen 6 through the second discharge hole 9, while the remaining portion of the polyurethane composite material scatters along the bottom edge of the distribution plate 7 and falls onto the filter screen 6. This achieves the diversion of the polyurethane composite material, ensuring that it falls evenly onto the filter screen 6, thus facilitating uniform filtration. This not only improves the filtration effect of the polyurethane composite material but also prevents a large amount of polyurethane composite material from accumulating on the filter screen 6 and causing blockage, thereby improving the filtration efficiency and achieving high-efficiency filtration. This also facilitates rapid discharge from the discharge system and convenient subsequent processing of the polyurethane composite material.

[0029] Furthermore, such as Figure 3 and Figure 4 As shown, the outer wall of the distribution plate 7 is also provided with multiple flow channels 10, and the tops of the multiple flow channels 10 extend to the upper end face of the distribution plate 7, and the bottoms are respectively connected to multiple second discharge holes 9. When the polyurethane composite material falls onto the distribution plate 7, the polyurethane composite material can be quickly guided into the second discharge holes 9 through the multiple flow channels 10, and then fall onto the filter screen 6 for filtration through the second discharge holes 9. This facilitates the diversion of the polyurethane composite material, further realizes the uniform filtration of the polyurethane composite material, and improves the filtration efficiency.

[0030] Meanwhile, in this embodiment, such as Figure 1 , Figure 2 as well as Figures 5-7 As shown, the storage tank 1 is also equipped with a cleaning component for cleaning the filter screen 6. The cleaning component includes a fixed box installed on one side of the storage tank 1 and a mounting plate 14 on the top of the filter screen 6. A movable plate 12 is provided on one side of the mounting plate 14, and a cleaning brush 13 that contacts the top of the filter screen 6 is installed at the bottom of the movable plate 12. The cleaning brush 13 can be a brush. An electric telescopic rod 4 is installed on one side of the fixed box, and the telescopic end of the electric telescopic rod 4 extends into the interior of the storage tank 1 and is fixedly connected to one side of the mounting plate 14. A waste discharge pipe 3 for discharging waste from the filter screen 6 is also connected to the side of the storage tank 1 away from the fixed box. The waste discharge pipe 3 has a gate that is easy to open and close.

[0031] When the filter screen 6 needs cleaning, the waste discharge pipe 3 can be opened, and the mounting plate 14 can be moved by the electric telescopic rod 4. Then, the mounting plate 14 drives the moving plate 12 to move along the top of the filter screen 6. After that, the moving plate 12 drives the cleaning brush 13 to move along the upper surface of the filter screen 6 to clean the filter screen 6 and push the cleaned waste into the waste discharge pipe 3, and then discharge it through the waste discharge pipe 3. This completes the cleaning of the filter screen 6, thereby preventing the filter screen 6 from becoming clogged and ensuring the filtration effect of the filter screen 6.

[0032] Furthermore, in order to ensure the airtightness of storage box 1, such as Figure 2 as well as Figures 5-7 As shown, a sealing ring 15 is also installed on the side of the mounting plate 14 away from the moving plate 12, and a sealing groove that matches the sealing ring 15 is provided on the inner wall of the storage box 1.

[0033] Furthermore, to prevent the polyurethane composite material from falling directly onto the movable plate 12, such as... Figure 2 and Figure 5 As shown, a downwardly inclined baffle is also installed on the inner wall of the storage box 1, and the baffle is above the moving plate 12 and the mounting plate 14. One side of the moving plate 12 is also obliquely cut to form an inclined part, which facilitates the diversion of the polyurethane composite material attached to its surface and reduces the residue of polyurethane composite material.

[0034] In another embodiment, such as Figure 2 as well as Figures 5-7 As shown, two snap-fit ​​blocks 16 are installed on one side of the movable plate 12, and a snap-fit ​​groove 17 is provided on the mounting plate 14 for the two snap-fit ​​blocks 16 to snap into. A handle is also fixed on the side of the movable plate 12 away from the mounting plate 14.

[0035] When the cleaning brush 13 needs to be cleaned or replaced, the sealed box door can be opened first, and then the moving plate 12 can be moved to the middle of the filter screen 6 by the electric telescopic rod 4. Then, the moving plate 12 can be pulled upward by the handle, so that the snap-fit ​​block 16 can be pulled out from the snap-fit ​​groove 17 to separate the moving plate 12 from the mounting plate 14. Then, the cleaning brush 13 at the bottom of the moving plate 12 can be cleaned or replaced. After cleaning or replacement, the moving plate 12 can be snapped onto one side of the mounting plate 14 by the snap-fit ​​block 16 and the snap-fit ​​groove 17 to install and fix the cleaning brush 13. This enables the quick disassembly and assembly of the cleaning brush 13, which is convenient for the regular cleaning or replacement of the cleaning brush 13. This is conducive to the normal use of the cleaning brush 13 and ensures the cleaning effect of the cleaning brush 13 on the filter screen 6.

[0036] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
