Description

Technical Field

[0001] This utility model relates to a fluidized bed drying device for foam boxes, specifically a fluidized bed drying device for foam box production, belonging to the field of fluidized bed drying technology for foam boxes. Background Technology

[0002] Foam boxes are box-shaped packaging containers made of foamed plastic (porous plastic). Foam is a type of plastic with many tiny pores inside. Foam boxes are commonly used for transporting fruit and packaging other goods. Fluidized bed drying is a process that uses fluidized bed technology to dry the raw material particles used in foam box production.

[0003] In the prior art, the authorized publication number CN217979681U discloses a fluidized bed drying device for foam box production, which includes a drying box, two sets of support columns, a conveying structure and a heating structure. The two sets of support columns are arranged opposite each other on the inner side of the drying box; the conveying structure is arranged between the tops of the two sets of support columns; the heating structure is arranged on the top of the drying box; and the drying structure is arranged on the inner top wall of the drying box.

[0004] Currently, to automate the conveying of foam boxes into the drying chamber, a conveyor belt is used to transport the foam boxes for drying. However, because the bottom of the foam box is in contact with the conveyor belt wall, the airflow at the bottom of the foam box is obstructed, thus affecting the drying of the bottom of the foam box. Therefore, a flipping mechanism is required to flip the foam box. However, this structure requires a sensing mechanism to detect the position of the foam box, clamp the foam box, and then flip and put it down. This series of steps makes the foam box drying process very troublesome. Moreover, the flipping process of the foam box will affect the subsequent foam box drying operation, thus reducing the working efficiency of the fluidized bed dryer used for foam box production.

[0008] Preferably, the conveying mechanism includes a mounting plate with a mounting groove at its top. Two synchronous pulleys are rotatably connected to the inner wall of the mounting groove, and an inner plate is fixedly installed thereon.

[0013] This utility model provides a fluidized bed drying device for foam box production, which has the following beneficial effects: 1. This fluidized bed drying device for foam box production uses two sets of staggered conveying mechanisms with a gap between adjacent mechanisms. Gas can pass through the gap to dry the suspended bottom of the foam box. When the foam box moves to the other set of conveying mechanisms, the contact position between the conveying mechanism and the foam box changes, thereby drying the entire bottom of the foam box. This method does not require any flipping operation; it only requires moving the foam box. Therefore, it can effectively improve the convenience and efficiency of using the fluidized bed drying device for foam box production.
