[0002] Automated casting machines are stable and reliable in performance, simple and safe to operate, and are suitable for the production of thin-film ceramics, papermaking, plastics, electronic components and other industries. The working principle of the casting machine is that the mixed slurry in the feeding device flows from the trough to the carrier tape, and a blank film is formed through the relative movement of the carrier tape (PET film tape) and the casting blade. The blank film is sent into the drying oven by the carrier tape for drying. Since the mixed slurry is directly output and conveyed to the drying oven, the drying time is long and the casting efficiency is low, which reduces the production efficiency of the casting film. Content of the Utility Model

An outlet seat is arranged in the feeding box. An outlet is arranged at the bottom of one side of the outlet seat. A trough is arranged in the outlet seat and is connected with the outlet. A heat transfer layer is arranged at the bottom of the trough; a heating box is arranged below the heat transfer layer. The heating box is detachably arranged in the outlet seat. A plurality of heating rods are arranged in the heating box. The top of the heating box is open and the top surface is attached to the heat transfer layer. The heating box is made of heat-insulating material; the heat of the heating rods is transferred to the trough through the heat transfer layer, and the mixed slurry flows from the outlet to the carrier tape for output after being heated in the trough.

[0005] Further, in the utility model, the top of the outlet seat is open, and the mixed slurry can be poured into the trough from the top. The bottom surface of the trough is an inclined surface inclined towards the outlet.

[0006] Further, in the utility model, an installation groove for inserting the heating box is arranged in the outlet seat. A switch door for closing the installation groove is hinged and installed on the side wall of the outlet seat. A switch handle is arranged on the switch door.

[0007] Further, in the utility model, the heating box includes an outer box body and support partition plates arranged on both sides inside the outer box body. Installation columns are respectively arranged at both ends of the heating rods. Positioning sockets for positioning and inserting the two installation columns are respectively opened on the two support partition plates.

[0008] Further, in the utility model, a plurality of the heating rods are equidistantly distributed along the heat transfer layer.

[0009] The utility model has the following advantages compared with the prior art: by arranging a heating box, the mixed slurry can be preheated, so that the slurry flowing to the carrier tape has a certain temperature, reducing the heating time required for subsequent casting and drying, improving the casting efficiency. The whole heating box is heat-insulated, and heat is only transferred to the heat transfer layer through the top opening to heat the bottom of the material tank, effectively avoiding potential safety hazards. The heating box is convenient to install and remove, and the heating rods inside can be taken out and replaced, which is convenient for maintenance and can greatly improve the production efficiency of the casting film.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0015] The following specifically describes the specific embodiments of the utility model with reference to the accompanying drawings.

[0016] Embodiment:

[0017] As shown in the accompanying drawings, a specific embodiment of a preheating and feeding device for a casting machine of the utility model is shown. As Figure 1 , Figure 2 shown, it mainly includes a feeding box 2 installed on a frame 1. An outlet seat 3 is arranged in the feeding box 2. The top of the outlet seat 3 is open. An outlet port 3a is arranged at the bottom of one side of the outlet seat 3. A material tank 3b connected to the outlet port 3a is arranged in the outlet seat 3. The mixed slurry can be poured into the material tank 3b from the top. The bottom surface of the material tank 3b is an inclined surface inclined towards the outlet port 3a, which is convenient for the mixed slurry to flow out from the outlet port 3a.

[0018] A heat transfer layer 3c is arranged at the bottom of the material tank 3b, and a heating box 4 is arranged below the heat transfer layer 3c. The specific installation method of the heating box 4 is that an installation groove for inserting the heating box 4 is arranged in the outlet seat 3, and a switch door 7 for closing the installation groove is hingedly installed on the side wall of the outlet seat 3. As Figure 3As shown, a switch handle 7a is also provided on the switch door 7. The switch door 7 can be opened through the switch handle 7a, and the heating box 4 can be taken out from the installation groove of the discharge seat 3.

[0019] Specifically, the structure of the heating box 4 is that the heating box 4 includes an outer box body 4a and support partition plates 4b provided on both sides inside the outer box body 4a. A number of heating rods 5 are provided in the heating box 4. Installation columns 5a are respectively provided at both ends of the heating rod 5. Positioning sockets 4c for positioning and inserting the two installation columns 5a are respectively opened on the support partition plates 4b on both sides. When installing the heating rod 5, only the installation columns 5a at both ends need to be aligned with the positioning sockets 4c on the support partition plates 4b on both sides and inserted, as Figure 4 shown.

[0020] In this embodiment, as Figure 2 shown, the top of the heating box 4 is open and the top surface is in contact with the heat transfer layer 3c. The heating box 4 is integrally made of heat-insulating material. A number of heating rods 5 are evenly distributed along the heat transfer layer 3c. The heat of the heating rods 5 is transferred to the material tank 3b through the heat transfer layer 3c. The mixed slurry flows from the discharge port 3a to the carrier tape 6 for output after being heated in the material tank 3b.

[0021] The preheating and feeding device of the casting machine of the present utility model can preheat the mixed slurry by setting the heating box 4, so that the slurry flowing to the carrier tape 6 has a certain temperature, reducing the heating time required for subsequent casting and drying, improving the casting efficiency. The heating box 4 is integrally heat-insulated, and only transfers heat to the heat transfer layer 3c through the open top to heat the bottom of the material tank 3b, which can effectively avoid potential safety hazards.
