Straight pull full open oven

This invention relates to an oven apparatus, and more particularly to a straight pull fully open oven apparatus.

An oven device suitable for a coating machine belongs to both sides of the door type and comprises an oven body and an inner space defined by the oven body. The oven body comprises a plurality of openable service ports, and the staff is When cleaning the internal space, the cleaning device can only be cleaned by opening the maintenance port, and the cleaning device is easy to cause a dead angle of cleaning, and cannot be cleaned, and the internal space is long-term. The dust and debris accumulated in the bottom layer are blown by the hot air passing through during the drying operation, and are mixed into the coating on the surface of the object to be coated, and contaminate the object to be coated, resulting in poor product yield and thus increased. manufacturing cost.

Another oven device of the prior art is of the clamshell type (single-single type), comprising two oven doors that can be opened up and down, each of the oven doors including a fixed side of the drive side, and a side opposite to the side of the drive and The operating edge that can be opened by the pneumatic cylinder can cause problems that cannot be cleaned up on the side of the transmission.

In addition, since the internal space is only connected to the outside through the maintenance ports, when the machine in the oven system is closed, the worker can only let the outside air enter the internal space by opening the maintenance ports. The speed of cooling is slow. At this time, if the staff cannot clean the interior space for a long time, it can only be cleaned in a high temperature environment, which causes a considerable degree of inconvenience.

Accordingly, it is an object of the present invention to provide a straight pull fully open oven apparatus that is easy to clean, fast to cool, and safe.

Therefore, the straight pull full-opening oven device of the present invention comprises a bracket unit, an oven unit, a gear synchronous lifting unit, at least one hot air unit and a safety unit.

The bracket unit includes four spaced apart uprights and a top frame disposed at the top end of the uprights. The uprights and the top frame cooperate to define an accommodation space.

The oven unit is disposed in the accommodating space, and includes a lower oven having a lower drying space, and an upper oven that is openably opened to the lower oven and has an upper drying space.

The upper oven is movable relative to the lower oven between a closed position and an open position. In the closed position, the upper oven cover is disposed in the lower oven, and in the open position, the upper oven is away from the lower oven.

The gear synchronous lifting unit is connected to the bracket unit and the upper oven for driving the upper oven to rise and fall between the open position and the closed position.

The hot air unit is disposed in the upper drying space in an up-and-down manner with the upper oven, and one end is disposed on the top frame, and a hot air is blown into the upper drying space and the lower drying space.

The safety unit includes four latch seats respectively disposed on the columns and four latch rods respectively slidably disposed horizontally through the corresponding latch seats. When the upper oven is in the open position, the upper oven is abutted against These latch pins.

The effect of the invention is that the upper synchronous oven and the hot air unit are lifted and lowered by the gear synchronous lifting unit, so that the worker has no dead angle during the cleaning, and the upper drying room can be raised to the open position through the upper oven. The drying space directly circulates with the outside air, and the safety unit improves the safety, thereby achieving the effects of convenient cleaning, rapid cooling, and good safety.
