Description

Technical Field

[0001] This invention relates to the field of coating machine oven technology, specifically a flexible substrate coating machine oven. Background Technology

[0002] Coating machines are mainly used for surface coating processes of films, paper, etc. They coat rolls of substrate with a layer of adhesive, paint or ink with specific functions, and after drying, cut them into sheets or roll them up. They use special multi-functional coating heads to achieve various forms of surface coating. The unwinding and winding of the coating machine are equipped with a full-speed automatic film splicing mechanism. Coating machines have been widely used in papermaking, film making, lithium-ion battery and other fields.

[0003] During the use of the coating machine, it is necessary to remove excess solvent from the coating layer of the flexible substrate to complete the curing of the substrate coating layer, substrate surface modification or related physicochemical reactions. The existing coating machine oven has low drying efficiency and cannot dry multiple flexible substrates at the same time. Excess solvent in the substrate coating cannot evaporate quickly, and the coated substrate needs to stay in the oven for a long time, which affects the normal production and use of flexible substrates. Summary of the Invention

[0004] The purpose of this invention is to provide a flexible substrate coating machine oven to solve the problem of inconvenience in using existing coating machine ovens.

[0005] To achieve the above objectives, the present invention provides the following technical solution: A flexible substrate coating machine drying oven includes a drying chamber and further includes: The drying chamber contains a heating roller, a movable plate and a partition. The movable plate has a sliding groove, and movable blocks are located on both sides of the sliding groove. A support plate is rotatably positioned between two movable blocks. Each support plate has a square groove, and a heating roller for drying the substrate is installed inside the square groove. A connecting pipe is located on both sides of the heating roller, and the connecting pipe is rotatably mounted on the support plate. An air inlet pipe is located outside the support plate and is connected to the interior of multiple heating rollers. Multiple air outlets are located outside the heating rollers. A fixed plate is located between the two support plates, and a horizontal plate is located at the bottom of the fixed plate. Multiple air outlet pipes are located on the horizontal plate.

The drive assembly, connected to the rotating rod, drives the piston to move left and right to introduce hot air into the intake pipe; The lifting mechanism, installed inside the drying chamber, can move the movable plate up and down.

[0006] Based on the above technical solutions, the present invention also provides the following optional technical solutions: In one alternative embodiment: the drive assembly includes a motor, a gear, and a transmission frame. The motor is located at the bottom of the partition, and the rotating end of the motor is connected to a rotating rod. A gear is located outside the rotating rod. A transmission rod is located on the side wall of the piston. One end of the transmission rod passes through a fixed cylinder and is connected to a transmission frame. A rack that meshes with the gear is located inside the transmission frame.

[0007] In one alternative embodiment: the lifting mechanism includes a screw, a lifting plate, and a connecting rod; a slider is slidably disposed on the outside of the movable plate; a connecting rod is disposed on the slider; the bottom end of the connecting rod is rotatably connected to the lifting plate; a screw is disposed on the partition plate; and the bottom end of the screw is rotatably disposed on the lifting plate.

[0012] Compared with the prior art, the beneficial effects of the present invention are as follows: The flexible substrate coating machine oven can simultaneously heat and dry multiple substrates, resulting in higher drying efficiency. The substrate passes horizontally between two heating rollers, and rotating fan blades blow hot air upwards to dry the substrate. The transmission frame drives the piston to move, and the hot air is forced into the inlet pipe through the outlet pipe. The hot air then enters the heating rollers along the inlet pipe, where it heats and dries the substrate body passing through it. The hot air is then discharged along the outlet and air duct, resulting in better drying of the substrate and achieving rapid drying of the flexible substrate, thus improving the production efficiency of flexible substrates.
