[0002] Teflon (PTFE), or polytetrafluoroethylene, has excellent chemical stability, corrosion resistance, heat resistance, non-stickiness and other characteristics, and is known as the "king of plastics". Teflon coating is a high-performance coating with comprehensive advantages that other coatings cannot compete with. It is widely used in various industries and solves many problems in the fields of chemical, petroleum, and pharmaceuticals. Teflon mesh belt is also known as Teflon mesh belt, Teflon conveyor belt, Teflon conveyor belt, PTFE conveyor belt and high-temperature conveyor belt. Teflon mesh belt is made of glass fiber cloth coated with Teflon resin to make Teflon (PTFE) conveyor belt base fabric, and it often needs to be dried during its production process.

[0007] In order to improve the stability of the movement of the two hot air boxes, as a preferred drying device for producing Teflon-coated metal mesh of the utility model, the two hot air boxes are slidably connected to the front and rear sides of the inner wall of the second U-shaped frame through sliding grooves.

[0008] In order to facilitate connecting the two hot air boxes and the air outlet ends of the two hot air blowers respectively through hoses of sufficient length, as a preferred drying device for producing Teflon-coated metal mesh of the utility model, hose connectors are opened through the right sides of the two hot air boxes.

[0011] In order to facilitate the installation and fixation of the first U-shaped frame, as a preferred drying device for producing Teflon-coated metal mesh of the utility model, a plurality of second installation holes are opened through the bottom side of the inner wall of the second U-shaped frame.

[0012] Compared with the prior art, the beneficial effects of the utility model are as follows:

[0013] The Teflon metal mesh is conveyed to the inside of the second U-shaped frame by a conveyor belt, and then the hot air can be blown to the inside of the two hot air boxes along with two hoses through the hot air blowers on the upper and lower sides. Since a plurality of ventilation holes are opened through the outer wall of the conveyor belt, the hot air can be blown to the upper and lower sides of the Teflon metal mesh through the plurality of air outlet pipes on the upper and lower sides, thereby facilitating double-sided drying of the Teflon metal mesh to improve the drying quality. Compared with the natural air drying method, the drying efficiency is improved.
