Description

Technical Field

[0001] The utility model relates to the technical field of vacuum furnace feeding, in particular to a feeding device with anti-swaying effect for a vacuum furnace. Background Art

[0002] A vacuum furnace is a furnace that uses a vacuum system in a specific space called a furnace chamber. It is carefully assembled from components such as a vacuum pump, a vacuum measuring device, and a vacuum valve to discharge some of the materials in the furnace chamber, so that the pressure in the furnace chamber is less than a standard atmospheric pressure, and the space in the furnace chamber is thus in a vacuum state. This is a vacuum furnace, which is mainly used for ceramic firing, vacuum smelting, degassing of electric vacuum parts, annealing, brazing of metal parts, and ceramic-metal sealing. During the loading process of the vacuum furnace, in order to protect the staff, the materials are pushed into the furnace chamber with the help of special loading tools. In order to prevent the materials from falling during loading, they are pushed manually, with one hand pushing and the other hand supporting. Since the materials are heavy, the force can be better controlled during the manual pushing process to avoid the materials from being pushed too fast. However, the following problems still exist during the loading process:

[0003] 1. The materials are placed in the middle of the storage plate, and then the whole device is pushed to send the materials into the furnace. However, the materials have a certain gravity, and they are easy to shake back and forth and slide to the ground during the pushing process;

[0004] 2. Different materials have different sizes and specifications. How to adjust the limit space according to the size of the material to make it suitable for materials of various specifications is a problem that needs to be solved at present. Utility Model Content
