Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of drying furnaces, in particular to a reverse rolling door device for drying furnaces. Background Art
[0002] Since the sprayed workpiece needs to be baked at a certain temperature for a certain period of time to meet the requirements of the paint, drying ovens are widely used in modern coating production lines, and the demand is gradually increasing. How to reasonably utilize space, reduce energy consumption, and reduce heat loss in drying ovens has also become a research direction in the optimization design of drying equipment.
[0003] Most of the existing drying furnaces that use a step-by-step suspended conveying system use a swing door device. When the workpiece is wider, the door of the drying furnace also becomes wider. When the door is open, it takes up more space on both sides, wasting space, resulting in a non-compact equipment layout and low space utilization of the factory building. Since the swing door is heavy and is directly installed on the drying furnace, its service life is shortened due to the long-term stress and vibration of the drying furnace. Utility Model Content

[0008] Preferably, a rotating shaft passing through both ends is provided in the middle of the rolling shutter machine case, the rolling shutter sprocket is sleeved on the outer surface of the rotating shaft and rotates synchronously, and the motor shaft of the rolling shutter motor is connected to the rotating shaft to provide power.
[0009] Preferably, the top rotating shaft is located directly above the rolling shutter machine box, the top sprocket is the same size as the rolling shutter sprocket and the upper and lower positions correspond one to one, so that the chain is in a vertical state.
[0010] Preferably, a door is provided at the front end of the drying oven chamber, and a sealing strip with a slot is provided around the door. Both ends of the insulation door panel are inserted into the sealing strip and can slide up and down, and both ends of the top of the insulation door panel are connected to the chain and rise and fall synchronously.
[0011] Preferably, the shutter motor is interlocked with the suspension conveying system. When the suspension conveying system transports the workpiece to the front of the drying furnace chamber, the shutter motor rotates forward to collect the insulation door panels into the shutter machine box so that the drying furnace chamber is in an open state.
[0012] Preferably, the shutter motor is interlocked with the suspension conveying system. When the suspension conveying system delivers the workpiece into the drying oven chamber and leaves, the shutter motor reverses to lift the insulation door panel from the shutter machine box to close the drying oven chamber.
[0013] The utility model provides a reverse rolling door device for a drying furnace, which has the following beneficial effects:
[0014] 1. The reverse rolling shutter door device used in the drying furnace has the effect of occupying a small space and making the equipment layout compact through the coordinated arrangement of the rolling shutter machine box, the chain and the thermal insulation door panel. When the drying furnace is opened, the thermal insulation door panel is rolled into the rolling shutter machine box and does not occupy the space around the drying furnace. The rolling shutter machine box is installed under the door opening of the drying furnace and does not interfere with the transportation of the workpiece, thereby making the reverse rolling shutter door occupy a small space and make the equipment layout compact.
[0015] 2. The reverse rolling shutter door device used in the drying furnace, through the coordinated arrangement of the rolling shutter machine case, chain and thermal insulation door panel, enables the reverse rolling shutter door device used in the drying furnace to avoid the drying furnace from being subjected to stress and vibration, thereby extending its service life. Since the rolling shutter machine case is directly installed on the ground, the drying furnace will not be subjected to stress. Since the thermal insulation door panel is pulled up by the chain and the support point of the chain is not on the drying furnace, the drying furnace will not be subjected to stress. Since the drying furnace only guides the movement of the thermal insulation door panel, the force is small, which can greatly reduce the impact of the vibration of the thermal insulation door panel on the drying furnace.

[0019] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

When the drier is reached, the cam 6 is engaged with the chain 7 and the control wheel 5. When the drier is reached, the cam 6 is engaged with the chain 7 and the control wheel 5. When the drier is reached, the cam 6 is engaged with the chain 7 and the control wheel 5. When the drier is reached, the cam 6 is engaged with the chain 7 and the control wheel 5. When the drier is reached, the cam 6 is engaged with the chain 7 and the control wheel 5. The front end of the drying furnace chamber 2 is provided with a door, and a sealing strip with a slot is provided around the door. The two ends of the thermal insulation door panel 9 are inserted into the sealing strip and can slide up and down. The two ends of the top of the thermal insulation door panel 9 are connected to the chain 8 and rise and fall synchronously. A suspension conveying system 10 is provided under the steel frame 1. The suspension conveying system 10 is used to transport workpieces. The roller shutter motor 5 is interlocked with the suspension conveying system 10, that is, the actions of the two cannot occur at the same time and run automatically in sequence according to the set steps. When the suspension conveying system 10 transports the workpiece to the front of the drying furnace chamber 2, the roller shutter motor 5 rotates forward to collect the thermal insulation door panel 9 into the roller shutter box 3 so that the drying furnace chamber 2 is in an open state. When the suspension conveying system 10 sends the workpiece into the drying furnace chamber 2 and leaves, the roller shutter motor 5 reverses to lift the thermal insulation door panel 9 from the roller shutter box 3 so that the drying furnace chamber 2 is in a closed state. The closed state can block the air heat exchange inside and outside the drying furnace chamber 2 as much as possible.
[0021] When in use, the thermal insulation door panel 9 is in an upward state for a long time. The thermal insulation door panel 9 can block the heat exchange of the air inside and outside the drying furnace chamber 2, so that the drying furnace chamber 2 is sealed and insulated. When it is necessary to add a workpiece to the drying furnace chamber 2, the workpiece is first lifted and transported to the front of the thermal insulation door panel 9 by the hanging conveying system 10. The roller shutter motor 5 is linked with the hanging conveying system 10. When the hanging conveying system 10 stops working, the roller shutter motor 5 starts working. The roller shutter motor 5 rotates forward to collect the thermal insulation door panel 9 into the roller shutter chassis 3, so that the drying furnace chamber 2 is in an open state. Further, the hanging conveying system 10 is After the workpiece is sent a little further in, it is unloaded, and the conveying system 10 is further suspended slightly away from the drying furnace chamber body 2 to make room for the worker to push the workpiece into the drying furnace. Furthermore, the roller shutter motor 5 is reversed to lift the thermal insulation door panel 9 from the roller shutter machine box 3 to close the drying furnace chamber body 2. Since the thermal insulation door panel 9 is rolled into the roller shutter machine box 3 when the drying furnace is opened and will not occupy the space around the drying furnace, the thermal insulation door panel 9 and other components are not directly installed on the drying furnace chamber body 2, so the reverse roller shutter door device will not damage the drying furnace chamber body 2 when used.
[0022] To sum up, when the drying furnace is opened, the reverse rolling shutter door device used in the drying furnace will roll the thermal insulation door panel 9 into the rolling shutter box 3 and will not occupy the space around the drying furnace. The rolling shutter box 3 is installed below the door opening of the drying furnace and will not interfere with the transportation of the workpiece, thereby making the reverse rolling shutter door occupy a small space and the equipment layout compact. Since the rolling shutter box 3 is directly installed on the ground, the drying furnace will not be subjected to stress. Since the thermal insulation door panel 9 is pulled up by the chain 8 and the support point of the chain 8 is not on the drying furnace, the drying furnace will not be subjected to stress. Since the drying furnace only guides the movement of the thermal insulation door panel 9, the force is small, which can greatly reduce the impact of the vibration of the thermal insulation door panel 9 on the drying furnace.
[0023] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
