Description

Sagger self-limiting overturning pouring device

Technical Field

The utility model belongs to the technical field of the supporting facility of electronic kiln, concretely relates to casket-like bowl is from spacing upset pouring device.

Background

The electronic kiln is mainly used for, but not limited to, firing electronic powder materials, and typical examples of the electronic powder materials include color phosphors, lamp powder, barium titanate, strontium titanate, yttrium oxide, titanium dioxide, zirconium dioxide, bismuth oxide, aluminum oxide, lead zirconate titanate, ferrite magnetic powder, and lithium iron phosphate. In the process of sintering electronic powder material in an electronic kiln, raw material or electronic powder material to be sintered is loaded into a sagger which is customarily called a crucible, so that the raw material or the electronic powder material to be sintered enters the electronic kiln from the sagger containing the electronic powder material to be sintered, the sintered electronic powder material (clinker) is loaded by the sagger and discharged from the kiln, and the raw material or the clinker is usually crushed by an automatic crushing device such as an electronic powder material crusher introduced in CN103521314B and then conveyed to a sagger dumping device by a conveying device, such as an automatic sagger dumping device with a function of horizontally correcting a turning table roller shaft recommended by CN108955270A and an automatic sagger dumping device for an electronic powder material production line provided by CN 103512368B.

The automatic sagger pouring devices of the prior art, including but not limited to the two patents mentioned above, have the following drawbacks: firstly, because a set of overturning plate rollers which correspond to the space between the upper connecting supporting rod and the lower connecting supporting rod of the overturning plate and are rotatably supported between the front overturning plate and the rear overturning plate in an interval state are used in the structure system of the sagger overturning and pouring device, and the set of overturning plate rollers are driven by the overturning plate roller driving mechanism to move, a set of overturning plate rollers can be rotatably supported between the front overturning plate and the rear overturning plate by means of bearings (each overturning plate roller is provided with a pair of bearings), however, the bearings can be blocked or even deadly due to the diffusion of the material dust in the working cavity of the pouring mechanism, and the clamping is not required for a long time, when the bearing of one or more overturning plate rollers in the set of overturning plate rollers has the above-mentioned situation, the problem that the saggars introduced from the saggar inlet are conveyed to the position between the front overturning plate and the rear overturning plate by the group of overturning plate roller shafts cannot be avoided, such as slipping, poor conveying stability and even conveying failure cannot be achieved, so that the problem that the saggars can be conveyed in place under normal conditions by the group of overturning plate roller shafts arranged in the area between the front overturning plate and the rear overturning plate is very high in fault probability of clamping stagnation and even clamping of the bearings, and frequent inspection and replacement of the bearings are needed, so that on one hand, the maintenance workload and the use cost of equipment are increased, on the other hand, the workload of equipment management and protection personnel is increased, and on the other hand, the problem of production pause and the like can be caused if the saggars cannot be found and disposed in time; secondly, because a sagger front side clamping and placing mechanism and a sagger back side clamping and placing mechanism (also called as a clamping mechanism) which are mutually matched and act in a cooperative way are needed, the structure is very complicated, and once the sagger front side and/or back side clamping and placing mechanism fails or the action harmony of the front side and the back side clamping and placing mechanism is inconsistent, the sagger is very easy to fall and even damage.
