TECHNICAL FIELD

[0001] The application relates to the technical field of mesh belt furnaces, and particularly relates to an automatic feeding and discharging device of an electronic ceramic silver-burning mesh belt furnace. BACKGROUND

[0002] The mesh belt furnace is a sintering furnace for realizing continuous conveying of parts in the furnace by a mesh belt protected by a muffle, and is mainly used for sintering of powder metallurgy products and reduction of metal powder, and pre-burning, burning or heat treatment process of electronic products in a protective atmosphere or air. The whole set of equipment is generally composed of a furnace body, a mesh belt transmission system and a temperature control system. The mesh belt furnace controls the temperature rise and temperature preservation through a temperature control instrument, and the temperature is fixed in several stages. The product is slowly pushed into the mesh belt, and after passing through different temperature stages, the heat treatment process is completed.

[0003] When the mesh belt furnace is used for sintering processing of parts, the common automatic feeding and discharging mechanism is a stepped elevator device which uniformly pushes the materials to the mesh belt conveyor, uniformly discharges the sintered materials, and has good use effect. However, the existing automatic feeding and discharging mechanism only has the function of simply conveying materials, and when discharging, the sintered parts often carry high temperature, and usually need to be cooled for a period of time before the materials can be collected, so that the processing efficiency is low.

[0004] Therefore, the application provides an automatic feeding and discharging device of an electronic ceramic silver-burning mesh belt furnace to solve the above problems. CONTENT OF THE INVENTION

Compared with the existing ordinary feeding and discharging equipment, the device can directly cool the high-temperature parts when discharging, and can quickly collect the materials without additional waiting or additional processing, thereby improving the processing efficiency.

[0014] The device installs a water receiving groove at the tail end of the cooling tank, the spring net receives the water hanging parts output from the transmission belt, the parts fall on the spring net and are discharged along the slope, and the spring net is contacted when falling to bounce, so that the water on the surface of the parts is shaken off and falls through the spring net surface into the water receiving groove, and the waste water is separated, facilitating subsequent part collection.

[0023] The automatic cooling and discharging mechanism 4 comprises a cooling tank 41 fixedly installed on the mesh belt conveyor 1 and away from the stepped feeding elevator 3 and filled with cooling liquid, and a transmission belt 43 fixedly installed in the cooling tank 41 and gradually rising in height from the end close to the mesh belt conveyor 1 to the end away from the mesh belt conveyor 1.

[0024] In use, the parts to be processed are poured into the stepped feeding elevator 3, the stepped feeding elevator 3 automatically lifts the materials to the mesh belt conveyor 1, the mesh belt conveyor 1 conveys the parts to the sintering furnace 2 for multi-step sintering, then the formed parts are output to the cooling tank 41, the cooling liquid in the cooling tank 41 directly cools the high-temperature parts, and at the same time, the driving motor 45 is started, the driving motor 45 drives the transmission belt 43 to rotate, the parts cooled in the cooling tank 41 are lifted out of the cooling tank 41 by the transmission belt 43 for collection, compared with the existing ordinary feeding and discharging equipment, the device can directly cool the high-temperature parts when discharging, and the collection can be quickly performed without additional waiting or additional processing, thereby improving the processing efficiency.

[0025] Specifically, the end of the mesh belt conveyor 1 away from the stepped feeding elevator 3 is fixedly installed with a guide hopper 42 extending towards the upper side of the cooling tank 41 and gradually descending in height. In use, the inclined guide hopper 42 receives the high-temperature parts output from the mesh belt conveyor 1, and directly guides the parts to the transmission belt 43 through the inclined surface, so that the transmission belt 43 can stably receive the parts and reduce the falling of the parts.

[0026] More specifically, a circulation pipe 46 is fixedly installed on the outer side wall of the cooling tank 41 in communication, and a condenser 47 is fixedly installed on the circulation pipe 46 in communication. In use, the condenser 47 circulates and cools the water in the cooling tank 41 through the circulation pipe 46, so that the cooling solution in the cooling tank 41 is always at a relatively low temperature, thereby ensuring the cooling efficiency.

[0027] Further, the outer side wall of the conveying belt 43 is fixedly installed with a plurality of evenly distributed material hanging strips 48. In use, the conveying belt 43 blocks the parts when conveying the parts, preventing the parts from rolling back along the surface of the conveying belt 43 during the rising process, thereby improving the conveying efficiency.

[0028] Embodiment 2

[0029] Different from embodiment 1, the parts are hung with water on the surface when collecting the parts, which is inconvenient for storage.
