Description

Technical Field

[0001] The utility model relates to the technical field of drying equipment, in particular to the technical field of time-adjustable drying equipment. Background Art

[0002] In the prior art, workpieces are typically dried by conveying them to a drying box via a conveyor belt. As the conveyor belt unloads the workpieces from the drying box, the drying process is complete. However, the loading and unloading times of these drying machines are typically set and cannot be adjusted. Some workpieces are larger and require more time to dry. Using the same drying time can result in incomplete drying. Utility Model Content

[0003] The purpose of this utility model is to solve the problems in the prior art and to provide a time-adjustable drying device that can solve the above problems.

[0004] To achieve the above-mentioned purpose, the utility model proposes a time-adjustable drying equipment, including a conveyor belt, a drying box and a hot air blower. The conveyor belt is driven by a conveyor roller, and the conveyor roller is driven to rotate by a rotating motor. The rotating motor is connected to a frequency converter, which controls the speed of the rotating motor. The frequency converter is connected to a controller. A drying box is provided above the conveyor belt, and a hot air blower is provided in the drying box. A mounting bracket is provided on the feed side of the drying box, and a visual inspection device is installed on the mounting bracket. The visual inspection device is connected to the controller.

[0005] Preferably, a blowing bracket is provided on the feed side of the mounting bracket, a blowing box is installed on the blowing bracket, and a drain trough is provided below the blowing box.

[0006] Preferably, the air inlet of the blowing box is connected to one end of the air pipe, and a heat collecting cover is provided on the discharge side of the conveyor belt, and the heat collecting cover is connected to the other end of the air pipe.

[0007] Preferably, the air pipe is fixed on the top of the drying box.

[0008] The beneficial effects of the present invention are as follows: the present invention arranges a visual inspection device in front of the drying box, performs a visual inspection on the workpiece before the workpiece enters the drying box, adjusts the conveying speed of the conveyor belt according to the inspected size, thereby controlling the drying time of the workpiece, and can automatically adjust the time of feeding and discharging the material into the drying box, which is very convenient; before entering the drying box, the workpiece is blown with air by a powerful fan in the blowing box to remove a large amount of water droplets first, thereby reducing the moisture entering the drying box and improving the drying efficiency; the blowing box can use the residual heat after drying to blow air, thereby reducing resource waste.

[0009] The features and advantages of the present invention will be described in detail through embodiments with reference to the accompanying drawings. BRIEF DESCRIPTION OF THE DRAWINGS
