[0002] EPP plastic is a polypropylene plastic foam material, a highly crystalline polymer with excellent performance. Its unique and superior properties have made it the fastest-growing environmentally friendly new pressure-resistant, cushioning and thermal insulation material. EPP products have excellent shock absorption and energy absorption, high recovery rate after deformation, excellent heat resistance, chemical resistance, oil resistance and thermal insulation. In addition, its light weight can significantly reduce the weight of items. EPP plastic is mainly produced from polypropylene, a thermoplastic resin made by polymerizing propylene. It is a white, waxy material with a transparent and light appearance. Polypropylene has excellent heat resistance. Products can be sterilized at temperatures above 100°C and will not deform at 150°C without external forces.
[0003] The production process for automotive EPP tool boxes involves pre-pressing raw materials, steam molding, drying and shaping, and finished product assembly. A common drying method involves stacking the demolded tool boxes on a rack and placing the rack inside a drying chamber. Annular heating tubes are installed along the inner wall of the drying chamber. These tubes heat the chamber, raising the temperature within the chamber and allowing the demolded tool boxes to continue drying and shaping within the chamber.
[0004] However, this drying method requires an additional drying room, which occupies a larger area. Furthermore, this product is made to order, and during batch production, when demand is low, using a drying room for drying wastes significant energy. Furthermore, stacking tool boxes on a rack reduces the drying efficiency due to the large space and low air flow, which prevents the tool boxes in the middle from drying properly, making it difficult to ensure accurate drying and shaping.

[0023] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by those skilled in the art to which this application pertains. The terms used herein in the specification of this application are for the purpose of describing specific embodiments only and are not intended to limit this application. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.
[0024] The specific embodiment of the drying device for the EPP spare tire tool box involved in the present utility model is as follows: Figures 1 to 5 As shown, the EPP spare tire tool box drying device includes a drying base 1 and two or more drying boxes 2 stacked on the drying base 1. The number of the drying boxes 2 can be increased or decreased as needed, and is not specifically limited in this embodiment.
[0025] The drying device further comprises a mobile trolley 3 having a vehicle plate 31 on which the drying base 1 is fixed. The bottom of the mobile trolley 3 has wheels 32 and a handle 33 connected to one side.
[0026] The drying base 1 has an air distribution cavity 11 within it, a dry air inlet 12 on the drying base 1, and an air supply port 13 on the top of the drying base 1. The drying base 1 is a rectangular box-shaped structure as a whole, with two dry air inlets 12 arranged side by side on the left side wall. The dry air inlet 12 is used to connect to an external high-temperature, high-pressure dry air generating device, such as a steam heat exchanger, to dry and pressurize the air before it enters the drying base 1. Of course, the specific method of generating high-temperature, high-pressure dry air is not specifically limited, and those skilled in the art can make any selection based on actual needs.
[0027] The front side of the drying box 2 has a switch door 5, the top of the drying box 2 has an exhaust port 27, and the interior has several rows of support structures for placing the spare tire tool box 4. The support structures are arranged side by side at intervals in the left and right directions, and a spare tire tool box is placed between two adjacent support structures. Each row of the support structures includes a bottom support member arranged at the bottom of the drying box 2 and a top support member arranged at the top of the drying box 2. The bottom support member and the top support member are staggered in the left and right directions to support the spare tire tool box 4 in an inclined position.
[0028] Specifically, the bottom support members are several support cylinders 21 arranged in the front-to-back direction, and the top support members are top support plates 22 extending in the front-to-back direction and fixed to the top of the inner wall of the drying box 2. Each row of support cylinders 21 and each row of support plates 22 are staggered in the left-right direction. This allows the tool box 4 to be tilted when inserted between the support cylinders 21 and the support plates 22, thereby ensuring that the drying air directly contacts the side walls of the tool box 4. The tilted placement, combined with the vertical ventilation method, ensures that each tool box 4 has the same drying efficiency.
[0029] The bottom of the drying box 2 is located within the outer contour of the air supply port 13 and is provided with several rows of air vents 23 arranged side by side in the left-right direction. Each row of air vents 23 has at least two or more air vents 23, and each air vent 23 is connected to the air supply port 13. Each row of air vents 23 is arranged in one-to-one correspondence with each group of support structures. Specifically, the inner hole of the above-mentioned support tube 21 is connected to the air vents 23 corresponding to a row of air vents 23, that is, the support tube 21 and the air vents 23 are coaxially arranged, so that the inner hole of the support tube 21 constitutes the air inlet into the drying box 2. Such a design can effectively save the internal space of the drying box 2 and adapt to more space for placing tool boxes 4.
[0030] In order to achieve the positioning and plugging between the drying base 1 and the drying box 2, and between the drying boxes 2 and the drying boxes 2, the bottom of the drying box 2 has a bottom positioning structure for adapting and positioning with the top of the adjacent drying box 2 and / or the drying base 1, and the top of the drying box 2 has a top positioning structure for adapting and positioning with the bottom of the adjacent drying box 2.
[0031] Preferably, the bottom positioning structure is an angle iron 25 provided at the four corners of the drying box 2 and extending downward, and the top positioning structure is a positioning slot 26 provided at the four corners of the top of the drying box 2 and extending downward.
[0032] In order to ensure that the gas does not overflow from between the drying base 1 and the drying box 2, a positioning ring platform 24 is provided at the edge of the bottom of the drying box 2 corresponding to the air supply port 13, and a positioning ring groove 14 is provided on the drying base 1 corresponding to the outer side of the positioning ring platform 24. The bottom of the positioning ring groove 14 is padded with a sealing gasket 29, and the insertion depth of the positioning ring platform 24 is higher than the insertion depth of the angle iron 25.
[0033] In addition, in order to ensure that the gas does not overflow from between the drying boxes 2 , the exhaust port 27 is surrounded by a sealing ring groove 28 for sealingly mating with the bottom of the adjacent drying box 2 .
[0034] When the air in the lower drying box 2 enters the upper drying box 2, the high-temperature, high-pressure dry air carries some moisture, but due to the faster air flow rate, it can further dry the upper tool box 4. The drying effect can be comprehensively judged based on factors such as the actual molding temperature, air flow rate, and pressure, and the appropriate number of drying boxes 2 can be adaptively selected.
[0035] The cavity within the bottom positioning ring 24 of the drying box 2 plays the same role as the air distribution cavity 11 of the drying base 1, achieving the effect of uniform air distribution.
[0036] Finally, it should be noted that the above embodiments are only used to illustrate and not to limit the technical solutions of the present invention. Any equivalent replacement of the present invention and any modification or partial replacement that does not depart from the spirit and scope of the present invention should be included in the scope of protection of the claims of the present invention.
