Technical Field

[0001] The utility model relates to the field of polyurethane foam production, in particular to an antifreeze polyurethane foam sealant filtering device. Background Technique

[0002] Polyurethane is divided into two types: soft polyurethane and rigid polyurethane. Soft polyurethane mainly has a thermoplastic linear structure. It has better stability, chemical resistance, resilience and mechanical properties than PVC foaming materials, has smaller compression deformation, and has good heat insulation, sound insulation, earthquake resistance and anti-toxic properties. Therefore, it is used as packaging, sound insulation and filtering materials. Rigid polyurethane plastics are light in weight, have excellent sound insulation and heat insulation properties, are resistant to chemical drugs, have good electrical properties, are easy to process, and have low water absorption. It is mainly used as a structural material for building, automobile, aviation industry and heat insulation. Polyurethane elastomers have properties between plastics and rubbers, are oil-resistant, wear-resistant, low-temperature resistant, aging-resistant, have high hardness and elasticity, and are mainly used in the shoe-making industry and the medical industry. Polyurethane can also be used to make adhesives, coatings and synthetic leather.

Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0031] To further understand the content of the present invention, the present invention will be described in detail with reference to the accompanying drawings.

[0032] Referring to Figure 1 , a freeze-resistant polyurethane foam sealant filtering device of the present invention includes a filtering box 1. Support legs 2 are fixedly connected to the four corners of the bottom of the filtering box 1 to support the filtering box 1. A feeding box 3 penetrates and is fixedly connected to the right side of the top of the filtering box 1. A sealing plate 5 is arranged at the upper end of the feeding box 3 to seal the filtering box 1 to avoid contact with air. The sealing plate 5 is rotatably connected to the feeding box 3 through a hinge 4. The sealing plate 5 is opened through the handle and the hinge 4, so that the polyurethane enters the filtering box 1 for filtering.

[0033] Referring to Figure 2 - Figure 4, linear guide rails 10 are fixedly connected to the inner walls at both the front and rear ends of the filtration box 1. The limiting blocks on the left and right sides of the linear guide rails 10 limit and control the sliding block 11 to prevent the sliding block 11 from derailing. The outer wall of the linear guide rail 10 is slidably connected to the sliding block 11. A first motor 12 is fixedly connected to the rear end of the front sliding block 11. The output end of the first motor 12 is fixedly connected to a groove box 13.

A filter screen plate 14 is arranged inside the groove box 13. A rotating plate 16 is arranged on the left side of the groove box 13. A rotating assembly is arranged at the bottom of the groove box 13. The rotating assembly includes a support plate 20. The support plate 20 is fixedly connected to the bottom of the front and rear ends of the groove box 13. A second motor 19 is fixedly connected through and inside the rear support plate 20. The output end of the second motor 19 is fixedly connected to a rotating rod 21. Cam 22s are fixedly connected to the outer circles at both the front and rear ends of the rotating rod 21. Springs 23 are fixedly connected to the inner walls at both the front and rear ends of the groove box 13, and the springs 23 are fixedly connected to the filter screen plate 14. The groove box 13 is moved to the bottom of the feed box 3 through the linear guide rail 10 and the sliding block 11. Polyurethane is poured into it. The second motor 19 drives the rotating rod 21 to rotate. The rotation of the rotating rod 21 drives the cams 22 at both the front and rear ends to rotate. The cams 22 contact the filter screen plate 14 at the top, causing the filter screen plate 14 to move up and down inside the groove box 13. The springs 23 at both the front and rear ends of the filter screen plate 14 cause the filter screen plate 14 to shake, filtering the impurities in the polyurethane. The filtered impurities then flow downward through the discharge hopper 9. The polyurethane inside is controlled through the discharge pipe and the control valve at the bottom of the filtration box 1.

[0034] Refer to Figure 2 - Figure 4 , chutes 7 are opened on the inner walls at both the front and rear ends on the left side of the filtration box 1. Sliders 6 are slidably connected to the inner walls of the chutes 7. There is a sealing gasket on the left side of the slider 6 to seal the holes of the chutes 7 and prevent contact with the external air. A waste chip box 8 is fixedly connected between the sliders 6. A discharge hopper 9 is fixedly connected to the inside on the right side of the filtration box 1, and the discharge hopper 9 penetrates through the filtration box 1. The filter screen plate 14 and the rotating plate 16 are rotatably connected through a hydraulic cylinder 17 at both the front and rear ends. The rotating plate 16 and the groove box 13 are rotatably connected through a rotating shaft 18. The impurities that are not filtered out are on the upper end of the filter screen plate 14. The linear guide rail 10 and the sliding block 11 move the groove box 13. The first motor 12 drives the groove box 13 to move, causing the groove box 13 to flip. Through the movement of the hydraulic cylinder 17, the rotating plate 16 is opened, and the impurities on the upper end of the filter screen plate 14 are poured into the waste chip box 8. The waste chip box 8 is taken out through the handle. The slider 6 slides on the inner wall of the chute 7 to take out the waste chip box 8.

[0035] Working principle: The sealing plate 5 is opened by the handle and the hinge 4, so that the polyurethane enters the filter box 1 for filtering, and the groove box 13 is moved to the bottom of the feed box 3 by the linear guide 10 and the sliding block 11, and the polyurethane is poured into the inside, and the rotating rod 21 is driven to rotate by the second motor 19, and the cams 22 at the front and rear ends are driven to rotate by the rotation of the rotating rod 21, and the cams 22 are contacted with the top filter plate 14, so that the filter plate 14 moves up and down in the groove box 13, and the springs 23 at the front and rear ends of the filter plate 14 are used to make the filter plate 14 shake, so as to remove impurities. Filter, the filtered impurities then flow downward through the discharge hopper 9, and the internal polyurethane is controlled by the discharge pipe and the control valve at the bottom of the filter box 1.
