The present invention will be described in detail below with reference to the accompanying drawings in conjunction with embodiments.

An automatic feeding device of a core pressing machine is schematically shown in fig. 1-6, and in the embodiment shown in the figures, the feeding device comprises: lifting unit, feed bucket 1 and storage vat 2. Storage vat 2 is used for storing the required thick liquids of ceramic core processing, and feed bucket 1 is used for to the inside thick liquids that fills of storage vat 2, lifting unit is used for driving feed bucket 1 and carries out the action of going up and down to make the thick liquids of 1 inside of feed bucket 2 inside flows to the storage vat.

Specifically, the lifting assembly comprises a guide rail 31 and a connecting block 32, wherein the guide rail 31 is arranged on the side wall of the storage vat 2, and the length direction of the guide rail 31 is parallel to the height direction of the storage vat 2. The connecting block 32 is arranged on the guide rail 31 in a liftable manner, the feeding barrel 1 is connected with the connecting block 32, and the bottom of the feeding barrel 1 is communicated with the storage barrel 2 through the feeding guide pipe 4.

When the connecting block 32 moves upward along the guide rail 31, the height of the supply bucket 1 will rise, and since the supply bucket 1 is communicated with the storage bucket 2 through the supply conduit 4, the rise of the height of the supply bucket 1 will cause a pressure difference between the supply bucket 1 and the storage bucket 2. At this time, the slurry inside the feeding barrel 1 flows into the storage barrel 2 under the action of the pressure difference, so that the purpose of replenishing the slurry inside the storage barrel 2 is achieved.

For whether the convenience needs to supply thick liquids to storage vat 2 and judges, this embodiment should be equipped with first level sensor 61 in storage vat 2 inside. When the liquid level height of storage vat 2 inside was less than the height of arranging of first level sensor 61, first level sensor 61 can the signals, and the staff can order about connecting block 32 this moment and drive feed vat 1 and rise the action to make the inside thick liquids of feed vat 1 get into inside storage vat 2.

Optionally, in order to avoid the phenomenon that the slurry is too much inside the storage vat 2, the worker may further set a second liquid level sensor 62 inside the storage vat 2, and the second liquid level sensor 62 is located above the first liquid level sensor 61. When the liquid level height inside the storage vat 2 and the arrangement height of the second liquid level sensor 62 are parallel and level, the second liquid level sensor 62 sends a signal, and the worker can stop the ascending action of the connecting block 32 at the moment, so that the storage vat 2 is prevented from generating slurry overflow.

Correspondingly, the arrangement height of the first liquid level sensor 61 and the second liquid level sensor 62 can be adjusted by a worker according to actual conditions, so that the slurry content in the storage vat 2 can be controlled.

In actual operation, slurry used in the ceramic core process may have a high viscosity, and thus the inside of the feed tub 1 may be bottom-stuck, thereby hindering the flow of the slurry. In addition, when the slurry has a large viscosity, the process of replenishing the slurry inside the supply tub 1 by the staff may cause air bubbles inside the slurry. If the core press is used to form the ceramic core from slurry containing air bubbles, air holes are formed in the ceramic core, and the use effect of the ceramic core is further affected.

In order to solve the above problem, the material conveying device of this embodiment further includes a stirring assembly. Specifically, the stirring subassembly includes: a stirring motor 51, a stirring shaft 52 and stirring blades. Wherein the stirring shaft 52 is disposed inside the supply tub 1, and the stirring blades are disposed on the sidewall of the stirring shaft 52.

When in use, the staff can drive the stirring shaft 52 to rotate through the stirring motor 51, and the stirring blade will stir the slurry inside the feeding barrel 1. As shown in fig. 3, the stirring vanes in this embodiment may include a first stirring vane and a second stirring vane 54, the first stirring vane is disposed above the second stirring vane 54, and the outer edge of the second stirring vane 54 contacts the inner wall of the bottom of the supply tub 1.

When the stirring shaft 52 starts to rotate, since the outer edge of the second stirring blade 54 contacts the inner wall of the bottom of the feed tub 1, the slurry adhered to the inner wall of the bottom of the feed tub 1 will be scraped off by the second stirring blade 54. Through the process, the bottom sticking phenomenon inside the feeding barrel 1 can be eliminated, so that the slurry can flow to the inside of the storage barrel 2 conveniently.

Fig. 6 is a schematic structural diagram of the stirring assembly in this embodiment, and as shown in the figure, the first stirring blade may include a connecting section 531 and a degassing section 532. Wherein one end of the connecting section 531 is connected with the stirring shaft 52, the other end is connected with the degassing section 532, and the length direction of the degassing section 532 is parallel to the axial direction of the stirring shaft 52.

When the stirring shaft 52 starts to rotate, the connection section 531 will drive the degassing section 532 to rotate, and the degassing section 532 will stir the slurry inside the feed tank 1. The upward movement speed of the bubbles can be accelerated through the stirring process, so that the air content in the slurry is reduced, and pores in the finished ceramic core are avoided.

As a further alternative of this embodiment, since the high viscosity slurry generally has a faster solidification speed, in order to avoid the slurry from clogging the apparatus due to solidification, the feed tank 1 is externally provided with a first heating sleeve 71, the storage tank 2 is externally sleeved with a second heating sleeve 72, and the feed conduit 4 is externally sleeved with a heating sleeve 73.
