Description

Technical Field

[0001] The utility model relates to the technical field of expandable polystyrene production, in particular to a pipeline feeding structure for expandable polystyrene production. Background Art

[0002] Expandable polystyrene resin is mainly used for foaming and is used as thermal insulation, heat insulation, shockproof, packaging material and floating products. General expandable polystyrene is suitable for packaging materials, and flame retardant expandable polystyrene is suitable for construction and insulation materials. Expandable polystyrene resin is cut and processed into shape. When cutting raw materials, the internal cutting machine will inevitably cut out larger than the common size or repeatedly cut out crushed materials. Before packaging, manual or mechanical screening is often required to filter out materials that do not meet the size. This requires manual or mechanical filtering after unloading, which is costly and requires many processes. The current expandable polystyrene unloading pipeline does not have the screening function, and there are certain defects and deficiencies that need to be improved. Utility Model Content

[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] Example

[0024] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, an embodiment of the utility model proposes a pipeline feeding structure for expandable polystyrene production, including a feeding pipe body 1, a cavity 5 arranged obliquely, a removable screening component 3 is installed at the cavity 5 of the feeding pipe body 1, the screening component 3 includes a screening frame 301 adapted on the cavity 5, and a screening plate 302 fixedly connected to the inner side of the screening frame 301, a T-shaped protrusion 304 is fixedly connected to the bottom of the screening frame 301, the T-shaped protrusion 304 is adapted to the T-shaped track groove 7 correspondingly opened on the feeding pipe body 1, a discharge port 8 for slag discharge is opened on one side of the cavity 5 of the feeding pipe body 1, and a discharge pipe 4 is fixedly connected to the discharge port 8 of the feeding pipe body 1.

[0025] It should be noted that the feed tube body 1 is used for feeding the shredded expandable polystyrene resin particles. An inclined cavity 5 is provided on the feed tube body 1. The cavity 5 penetrates both sides of the feed tube body 1 for installing the screening component 3. The screening component 3 is composed of a screening frame 301 adapted to the cavity 5 and a screening plate 302 fixedly connected to the screening frame 301. The screening frame 301 and the screening plate 302 are both inclined. When the expandable polystyrene resin particles flow on the screening plate 302, the expandable polystyrene resin particles can be extended. The screening time of the particles is shortened, thereby increasing the screening effect. A T-shaped protrusion 304 is set at the bottom of the screening frame 301. During assembly, the T-shaped protrusion 304 is adapted to the T-shaped track groove 7 of the discharge pipe body 1 to support the screening frame 301, and can realize the sliding limit function during the assembly of the screening frame 301, which is convenient for the assembly of the screening frame 301. A discharge port 8 is opened on one side of the cavity 5 of the discharge pipe body 1, and the large particles screened out can be discharged through the discharge port 8 and the discharge pipe 4, thereby realizing the preliminary screening of the expandable polystyrene resin particles.

[0026] like Figure 4 As shown, in some embodiments, the upper surface of the screening frame 301 and the upper surface of the screening plate 302 are on the same horizontal plane.

[0027] It should be noted that the screening plate 302 is flush with the upper surface of the screening frame 301 to facilitate the flow of the expandable polystyrene resin particles.

[0028] like Figure 1 , Figure 2 and Figure 4 As shown, in some embodiments, a stop plate 303 is fixedly connected to one side of the screening frame 301, and a support 305 is fixedly connected to the other side of the screening frame 301, and a positioning seat 6 is fixedly connected to one side of the discharge pipe body 1 located at the cavity 5, and a screw 306 is threadedly connected to the corresponding holes of the positioning seat 6 and the support 305.

[0029] It should be noted that the setting of the stop plate 303 can play a stopping and limiting role when the screening frame 301 is assembled. During assembly, the screening frame 301 is adapted to the cavity 5, and the T-shaped protrusion 304 slides along the T-shaped track groove 7 to realize the assembly of the screening frame 301 on the cavity 5. After that, the stop plate 303 is abutted against one side of the discharge pipe body 1, and the support 305 is matched on one side of the positioning seat 6. The screw 306 is installed in the corresponding holes of the positioning seat 6 and the support 305 to fix the screening frame 301. When dismantling, the screw 306 can be disassembled, which is very convenient.

[0030] like Figure 3As shown, in some embodiments, a guide plate 9 is fixedly connected to the inner side of the feed pipe body 1 above the screening component 3 , and an opening 10 is formed on one side of the feed pipe body 1 located on the guide plate 9 .

[0031] It should be noted that the setting of the guide plate 9 can achieve the guiding effect of the expandable polystyrene resin particles, so that the expandable polystyrene resin particles flow into the upper part of the screening plate 302, and the expandable polystyrene resin particles are fully screened. By setting an opening 10 on one side of the feed pipe body 1, the clogging of the expandable polystyrene resin particles can be avoided.

[0032] like Figure 3 As shown, in some embodiments, the feed pipe body 1 is fixedly connected to a protective cover 2 on the outside of the opening 10 , and an inclined plate 11 is provided at the bottom of the protective cover 2 .

[0033] It should be noted that by fixing the protective cover 2 on the outside of the opening 10 of the discharge pipe body 1 and providing an inclined plate 11 at the bottom of the protective cover 2, the protective cover 2 can achieve the protective effect of the expandable polystyrene resin particles, and the setting of the inclined plate 11 facilitates the discharge of the expandable polystyrene resin particles.

[0034] like Figure 1 As shown, in some embodiments, the cross-section of the feed tube body 1 is rectangular.

[0035] It should be noted that the cross-section of the feed tube body 1 is rectangular. The rectangular feed tube does not affect the feeding of expandable polystyrene resin particles. At the same time, it is convenient for the opening of the cavity 5 and the installation of the screening component 3. Even if the cavity 5 is opened on the feed tube body 1, the overall strength of the feed tube body 1 can be guaranteed.

[0036] Finally, it should be noted that the above description is only a preferred embodiment of the utility model and is not intended to limit the utility model. Although the utility model is described in detail with reference to the above embodiments, those skilled in the art can still modify the technical solutions recorded in the above embodiments or replace some of the technical features therein by equivalents. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model shall be included in the protection scope of the utility model.
