Description

Technical Field

[0001] This invention belongs to the field of material processing technology, and specifically relates to a device for rapid and automatic melting of semi-solid materials. Background Technology

[0002] Currently, the melting of semi-solid matrices in the production processes of pharmaceuticals, cosmetics, and food industries still faces numerous technical challenges. Existing material melting machinery often lacks rapid heating and automatic lifting capabilities, and it also fails to adequately address the issue of material contamination. Furthermore, it is inadequate in terms of the convenience of material loading and unloading and the precision of temperature control. Existing equipment is relatively rudimentary in operation, lacking automated discharge design, resulting in low work efficiency and high labor intensity. In addition, the inaccurate temperature control of existing equipment easily leads to temperature exceeding limits or mechanical jamming, further causing problems such as poor flowability of semi-solid materials, difficulty in discharge, and material blockage.

[0003] Therefore, there is an urgent need for a melting device that can achieve rapid and uniform heating and melting, while also ensuring precise temperature control, automated lifting and lowering, and pollution prevention. Summary of the Invention

[0020] 4. The heating coil of this device uses a proportional regulating valve to control the temperature, and a temperature sensor is installed at the vacuum outlet, so the temperature control is accurate and the material temperature is uniform when heated by the heating coil.

[0021] 5. The heating coil of this device not only serves the purpose of heating, but also, during the process of the heating coil entering the material bucket, it can be hydraulically controlled to vibrate slightly. By slightly shifting the heating coil longitudinally and laterally, the material is appropriately stirred, which can also play a stirring role. No additional stirring mechanism is required, which further simplifies the device. Moreover, it can also achieve further uniformity of material temperature without manual intervention.

[0039] The working method of the above-mentioned rapid automatic melting device for semi-solid materials is as follows:

[0040] 1. Start the hydraulic station 7. The hydraulic station 7 controls the piston rod of the hydraulic cylinder 8 to rise. The piston rod of the hydraulic cylinder 8 drives the lower frame connecting rod 13 to rotate in the vertical plane with its connection point with the vertical support 10 as the fulcrum. At this time, the end of the lower frame connecting rod 13 connected to the connecting support 11 rotates counterclockwise, and this end rises. The connecting support 11, driven by the lower frame connecting rod 13, rotates counterclockwise and continuously rises. Driven by the connecting support 11, the upper frame connecting rod 12 rotates in the vertical plane with its connection point with the vertical support 10 as the fulcrum. At this time, the end of the upper frame connecting rod 12 connected to the connecting support 11 rotates counterclockwise and continuously rises. The lifting sleeve 5, driven by the upper frame connecting rod 12 and the lower frame connecting rod 13, rotates counterclockwise and continuously rises. The lifting sleeve 5 drives the coil fixing frame 19 and the heating coil 16 to rise continuously.

[0041] 2. When the steam coil 16 is raised to the highest position, the operator pushes the transport vehicle through the guide rail to move the material bucket 21 to the bottom of the working box 1. When the material bucket 21 touches the material bucket limit block 4, the operator stops pushing the transport vehicle, places the material bucket 21 containing the material at the designated position at the bottom of the working box 1, and the operator exits the transport vehicle and manually closes the box door.

[0042] 3. Operate the hydraulic station 7 to control the piston rod of the hydraulic cylinder 8 to slowly descend. As the piston rod of the hydraulic cylinder 8 slowly descends, the steam coil 16 also slowly descends. While descending, the steam coil 16 melts the semi-solid matrix in the material bucket 21. During the descent of the steam coil 16, the hydraulic cylinder 8 can be controlled to make the heating coil 16 slightly vibrate to stir the material and ensure the uniformity of the melting. When the steam coil 16 descends to its lowest position, the suction port of the vacuum suction pipe 15 is slightly higher than the bottom of the material bucket. When the material temperature reaches the set value (measured by the temperature sensor), the semi-solid matrix is ​​completely melted. The vacuum pump is turned on, and the melted material is sucked into the storage container through the vacuum suction pipe 15. When the material in the material bucket 21 is completely evacuated, the vacuum is broken.

[0043] 4. Control the hydraulic station 7. When the steam coil 16 is raised to the highest position, the operator takes out the empty material bucket 21 by means of a transport vehicle.
