Description

Technical Field

[0001] The utility model relates to the technical field of polystyrene insulation box production, in particular to a polystyrene insulation box production preheating device. Background Art

[0002] According to different production processes, polystyrene foam is divided into two types: molded polystyrene board (EPS) and extruded polystyrene board (XPS). The interior of the extruded polystyrene insulation board (XPS) is an independent closed bubble structure. It is an environmentally friendly insulation material with beneficial properties such as low thermal conductivity, high pressure resistance, moisture resistance, airtightness, non-absorption, light weight, corrosion resistance, and long service life.

[0003] After searching, it was found that Chinese patent announcement No. CN219519091U discloses a polystyrene insulation board raw material preheating device. The device can retain large pieces of raw materials in the heating box for further heating through a filter plate, and can clamp small-volume block raw materials on the filter net through a filter net, and further heat them in the insulation box to melt into a raw liquid, thereby preventing the block raw materials from directly entering the discharging mechanism and clogging the discharging mechanism. However, during the heating process of the device, it is difficult to fully mix the raw materials accumulated inside the insulation box with the heat, resulting in poor heating effect of the raw materials accumulated inside after some of the raw materials are heated, affecting the dissolution efficiency, so it is necessary to improve the existing device to meet actual needs. Utility Model Content

[0004] 1. Technical issues to be resolved

[0005] In view of the deficiencies in the prior art, the utility model provides a preheating device for the production of a polystyrene insulation box, which has the advantages of first avoiding blockages during the feeding process, and secondly separating the raw materials by size, so that the raw materials dissolve more rapidly during the heating process, thereby preventing large pieces of raw materials from affecting the heating and dissolving effect, and at the same time stirring the raw materials inside the heating bin to promote the internal dissolution effect, thereby solving the above-mentioned technical problems.

[0010] Preferably, two groups of discharge leakage plates are provided.

[0011] Through the above technical scheme, the raw materials crushed by the crushing knife fall into the heating bin through two sets of discharge leak plates and the discharge pipe, while larger pieces of raw materials continue to stay in the feed barrel through the isolation of the discharge leak plates until the crushing knife continues to crush them to a suitable size that leaks out of the discharge leak plates and falls into the heating bin. This structure separates the size of the raw materials, so that the raw materials dissolve more quickly during the heating process, avoiding large pieces of raw materials affecting the heating and dissolving effect.

[0014] Preferably, a stirring shaft is fixedly mounted at the axis of the first motor, and a stirring rod is fixedly mounted at the bottom end of the outer peripheral surface of the stirring shaft.

[0016] Preferably, a group of discharge valves are fixedly installed on the side of the discharge pipe.

[0017] Through the above technical solution, when the raw materials are completely decomposed, the discharge valve is opened to allow the dissolved raw materials inside the heating bin to be discharged through the discharge pipe, which is convenient for unloading.
