Description

Technical Field

[0001] The utility model relates to the field of paper mold wet blank drying devices, in particular to a paper mold drying equipment tray and paper mold drying equipment. Background Art

[0002] With the popularization and improvement of environmental awareness, more and more industries are using paper mold products to replace plastic products, giving rise to a variety of paper mold production and manufacturing equipment. Paper mold drying is an important part of the paper mold production and manufacturing process. Paper mold drying equipment places the wet paper mold on a tray and transports it to the drying area. It draws air from the vents on the tray and dries the wet paper mold into shape, producing a variety of paper mold products.

[0003] However, the ventilation holes on the tray of the current paper mold drying equipment are evenly distributed mesh holes, and the wet paper mold blanks can only be evenly air-drawn. For the wet paper mold blanks with two structures, due to the inconsistent structures of the two parts, if the same amount of air suction is used for drying on both sides, the part with a simple structure will inevitably be dried earlier than the part with a complex structure, resulting in a waste of air consumption in the simple structure part and extending the drying time of the entire product. The current unreasonable distribution of air suction volume on the tray of the paper mold drying equipment needs to be improved urgently. Utility Model Content

[0004] The purpose of the utility model is to overcome the shortcomings of the prior art and provide a paper mold drying equipment tray, which is equipped with two convection structures with different convection areas. When drying wet paper mold blanks with the two structures, the air suction amount is reasonably distributed, the drying time is shortened, and the drying effect of the wet paper mold blank drying device is improved.

For the wet paper mold blanks with two structures, the complex structural part is placed on the first convection structure with a larger convection area, and the simple structural part is placed on the second convection structure with a smaller convection area. When air suction is used to dry the wet paper mold blanks, due to the different convection areas, the air suction amount allocated to the first convection structure is larger, and the air suction amount allocated to the second convection structure is smaller, thereby achieving the effect of reasonably distributing the air consumption.

[0009] Preferably, a support bar is provided between the first convection structure and the second convection structure, and a protrusion is provided between two adjacent storage stations, the support bar and the protrusion are used to support at least a part of the wet paper mold blanks to prevent the wet paper mold blanks from becoming soft and deformed and reduce the loss of the wet paper mold blanks. In addition, the protrusion also serves to block adjacent wet paper mold blanks to avoid shaking during transportation of the tray of the paper mold drying equipment, and the displacement and collision of two adjacent wet paper mold blanks, which may cause damage to the wet paper mold blanks.

[0010] Preferably, the pallet body includes a pallet frame with a hollow structure, so that the weight of the pallet frame is evenly distributed on the borders on both sides, reducing the load on the conveyor belt and improving the stability of the pallet body during movement; the first placing plate and the second placing plate are an integrated structure, and the first placing plate and the second placing plate are arranged on the pallet frame to keep the wet paper mold blanks at a fixed interval.

[0011] Preferably, the recessed portion is in an inverted trapezoidal shape, and the second convection holes are strip-shaped, and the second convection holes are evenly distributed on the bottom surface and side walls of the recessed portion, so that the bottom surfaces of wet paper mold blanks of different areas can retain space between the tray body, thereby increasing the contact area between the suction airflow and the bottom surface of the wet paper mold blank, and improving the drying effect of the wet paper mold blank drying device.

[0012] Preferably, the support bar is a V-shaped bent plate; the V-shaped triangular structure enables the center of gravity of the support bar to be located at the lower part, thereby stabilizing the support bar on the pallet body.

[0013] The utility model also provides a paper mold drying equipment, which includes a frame, a drying chamber, a conveyor line and a pneumatic turning device, wherein the drying chamber is arranged in the frame, the pneumatic turning device is arranged at the feeding end of the conveyor line, the conveyor line is arranged in a coil along the drying chamber, and the paper mold drying equipment tray is arranged on the conveyor line through a latch, and the latch is connected to the paper mold drying equipment tray through a connecting arm, so that the paper mold drying equipment tray remains horizontal during the conveying process, thereby preventing the wet paper mold blanks from falling.

[0014] Preferably, a blocking plate and a discharge chute are provided on the lower conveyor line outside the frame, the blocking plate is used to block the connection arm from moving forward when the tray of the paper mold drying equipment moves forward along the conveyor line, so that the tray body is tilted, thereby realizing the flipping and unloading of the tray of the paper mold drying equipment, and a support plate is provided on the discharge chute, and the support bar is used to correspond to the support plate during unloading, so as to realize the unloading of the wet paper mold blank at the accurate position of the unloading end.

[0015] Preferably, the pneumatic flipping device is arranged at the feed end of the conveyor line.
