Description

Technical Field

[0001] This utility model relates to the field of silicone paper drying technology, and in particular to a drying channel for a silicone paper coating machine. Background Technology

[0002] Silicone paper is a commonly used packaging paper, typically used in food packaging. It has a three-layer structure: a base paper, a coating layer, and a silicone oil layer. During production, the silicone paper is coated with silicone, and then dried in a drying tunnel.

[0003] Utility model patent CN213377625U discloses a drying channel for a silicone paper coating machine, including a housing of the drying channel, a conveying device for conveying silicone paper inside the housing, and a drying device for drying the silicone paper on the housing. This invention achieves the drying of silicone paper by spraying dry air directly onto the conveyor belt through evenly distributed air nozzles on the exhaust pipe. However, the equipment has many components, resulting in relatively high costs for both equipment purchase and maintenance.

[0004] Based on this, the present invention designs a drying channel for a silicone paper coating machine to solve the above-mentioned problems. Utility Model Content

[0005] The purpose of this invention is to provide a drying channel for a silicone paper coating machine, thereby solving the problems in the prior art.

[0006] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0007] A drying channel for a silicone paper coating machine includes a conveyor belt that horizontally runs through a drying device. The drying device includes a cover and a base. A heating tube is installed inside the cover. A heat collection air pipe is provided between the heating tube and the cover. The heat collection air pipe is connected to an air outlet pipe. An air inlet is opened on the cover, and the heat collection air pipe is connected to the air inlet pipe. A rotating drum is horizontally provided above the conveyor belt. One end of the rotating drum is connected to the air outlet pipe, and the other end is connected to the exhaust pipe. The air outlet pipe is connected to an exhaust fan.

[0008] The box cover is hinged to the base via a hinge shaft, and the box cover and the base are respectively provided with an upper opening and a lower opening to accommodate the conveyor belt.

[0009] A lifting column is installed between the lid and the base. The upper and lower ends of the lifting column are respectively hinged to the connecting ears. The connecting ears are fixed to the outer edge of the lid and the base by an L-shaped connecting plate.

[0010] Bearings are installed on both sides of the rotating drum. The bearings are rotatably mounted on the bracket, and the air outlet pipe and exhaust pipe are rotatably connected in the center of the bearing.

[0011] A dust filter is installed on the air inlet.

[0012] The heating element is fixed to the inner wall of the box cover by a mounting plate.

[0013] This utility model has the following beneficial effects:

[0014] This invention uses a heating tube to heat the silicone paper on the conveyor belt. The residual heat from the heating tube can also heat the heat collection duct, which in turn heats the rotating drum. The rotating drum can then be used for shaping. This invention is simpler than existing equipment, and the cover can be opened via a lifting column for easy maintenance. Attached Figure Description
