Description

Technical Field

[0001] The utility model relates to the technical field of curing furnace accessories, in particular to a curing furnace with a discharge port having a secondary time-delay alarm function. Background Art

[0002] The curing furnace is a baking device in the quartz crystal production process. In the absence of a fully automatic production line, the materials are collected manually after baking in the curing furnace. The original device has only one alarm design. When the alarm sounds, most of the material tray at the discharge port is still in the equipment channel. In addition, there are many equipment in the workshop. When there are similar alarm devices or the sound is not loud, employees cannot correctly judge the material collection time. Therefore, materials are often not collected in time or forgotten, causing the material tray to be blocked at the exit, which will cause the conveyor belt to be stuck and damage the machine, and the internal material tray to overturn. Due to the strict requirements on materials, once the materials are baked and turned over, they will be reworked and produced, which is not only time-consuming and material-intensive, but also affects delivery time and other serious machine failures and large production losses.

[0003] For example, a material inlet and outlet transmission device for a drying and curing furnace with publication number CN217497653U includes a material transmission belt, a bottom plate is arranged at the lower side of the material transmission belt, and vertical plates are fixedly connected at the front and rear sides above the bottom plate, a rotating seat is connected to the vertical plate by bolts, the rotating seat is inserted into the vertical plate, and the positions of the rotating seats at the front and rear sides correspond to each other front to back, a rotating shaft is rotatably connected in the rotating seat by a bearing, and a roller body is connected between the rotating shafts at the front and rear sides by a coupling, and bristles are installed on the outer wall of the roller body, and the bristles are in contact with the lower end of the material transmission belt, and the rear end of the rotating shaft on the rear side extends to the rear side of the installed rotating seat, and the rotating shaft is driven to rotate by a motor, thereby driving the roller body to rotate, and the material transmission belt is cleaned by the bristles, and there is no need for staff to stop the machine for manual cleaning. It is easy to use and has high efficiency.

[0004] The above technical solution has the problem of poor reminder effect during material discharging in practical application.

[0005] Therefore, it is necessary to invent a curing furnace with a discharge port having a secondary delayed alarm function to solve the above problems. Utility Model Content
