Abstract

A drying device that includes a drying furnace having an inlet and an outlet, a drying unit installed inside the drying furnace and for drying a to-be-dried object, a number of upper and lower rolls alternately arranged at internal top and bottom portions of the drying furnace, and a roll driver connected to the plurality of upper and lower rolls and moving the upper rolls upwardly and the lower rolls downwardly, wherein after the to-be-dried object is transferred from the inlet to the outlet, the roller driver moves the upper rolls downwardly, moves the lower rolls upwardly, or moves the upper rolls downwardly and the lower rolls upwardly.

First claim

What is claimed is:

1. A drying device comprising:
a drying furnace having an inlet and an outlet;
a drying unit installed inside the drying furnace and for drying a to-be-dried object;
a plurality of upper and lower rolls alternately arranged at internal top and bottom portions of the drying furnace, said top and bottom portions being on opposite sides of the drying furnace;
a roller driver connected to the plurality of upper and lower rolls and moving the upper rolls upwardly toward the top portion and the lower rolls downwardly toward the bottom portion;
a to-be-dried object connection unit attached to an exterior of the drying furnace adjacent to the outlet having a driving member and a connection member, said driving member includes a body containing a variable length part, said connection member is installed at a front end of the variable length part; and
a driving controller controlling the roller driver and the to-be-dried object connection unit, said driving controller extends the variable length part from the outlet in a telescoping manner linearly along the midline of the drying furnace between the plurality of upper rolls and the plurality of lower rolls out through the inlet with the connection member grasping the to-be-dried object outside of the drying furnace, upon grasping the to-be-dried object the driving controller retracts the variable length part pulling the to-be-dried object through the drying furnace linearly along the midline of the drying furnace and out through the outlet,
wherein when the to-be-dried object is transferred from the inlet to the outlet, the roller driver controlled by the driving controller moves the upper rolls downwardly toward the bottom portion and the lower rolls upwardly toward the upper portion with each of the upper and lower rollers moved individually, independently and sequentially in an up and down direction toward the upper rollers and/or the lower rollers according to a transfer location of the to-be-dried object as the to-be-dried object is pulled through the drying furnace.

2. The drying device of claim 1 , wherein the to-be-dried object connection unit transfers the to-be-dried object positioned inside the drying furnace from the inlet to the outlet along empty spaces between the plurality of upper and lower rolls.

3. The drying device of claim 1 , wherein the driving member includes one or more driving members.

4. The drying device of claim 1 , wherein the variable-length part is a bar antenna shape.

5. The drying device of claim 1 , wherein the connection member are tongs or clamps.

6. The drying device of claim 1 , wherein the drying device is an electrode plate drying device for a secondary battery.

7. A drying device comprising:
a drying furnace having an inlet and an outlet;
a drying unit installed inside the drying furnace and for drying a to-be-dried object;
a plurality of upper and lower rolls, said plurality of upper rolls arranged at an internal top portion of the drying furnace and said plurality lower rolls arranged at a bottom portion of the drying furnace in which the top portion of the drying furnace is on an opposite side of a midline of the drying furnace to the bottom portion of the drying furnace;
a roller driver connected to the plurality of upper rolls to move the plurality of upper rollers toward the bottom portion or the upper portion of the drying furnace and connected to the plurality of lower rolls to move the plurality of lower rolls toward the upper portion or the bottom portion of the drying furnace;
a to-be-dried object connection unit attached to an exterior of the drying furnace adjacent to the outlet having a driving member and a connection member, said driving member includes a body containing a variable length part, said connection member is installed at a front end of the variable length part; and
a driving controller controlling the roller driver and the to-be-dried object connection unit, said driving controller extends the variable length part from the outlet in a telescoping manner linearly along the midline of the drying furnace between the plurality of upper rolls and the plurality of lower rolls out through the inlet with the connection member grasping the to-be-dried object outside of the drying furnace, upon grasping the to-be-dried object the driving controller retracts the variable length part pulling the to-be-dried object through the drying furnace linearly along the midline of the drying furnace and out through the outlet,
wherein after the to-be-dried object is transferred from the inlet to the outlet, the roller driver controlled by the driving controller moves the upper rolls toward the bottom portion of the drying furnace and moves the lower rolls toward the upper portion of the drying furnace with each of the upper and lower rollers are moved individually, independently and sequentially in an up and down direction toward the upper rollers and/or the lower rollers according to a transfer location of the to-be-dried object as the to-be-dried object is pulled through the drying furnace.

8. The drying device of claim 7 , wherein the to-be-dried object connection unit transfers the to-be-dried object positioned inside the drying furnace from the inlet to the outlet along empty spaces between the plurality of upper and lower rolls.

9. The drying device of claim 7 , wherein the driving member includes one or more driving members.

10. The drying device of claim 7 , wherein the variable-length part has a bar antenna shape.

11. The drying device of claim 7 , wherein the connection member are tongs or clamps.

12. The drying device of claim 7 , wherein the drying device is an electrode plate drying device for a secondary battery.
