Description

Technical Field

[0001] The utility model relates to the technical field of zirconia processing equipment, and particularly relates to a continuous zirconia block cutting device. Background Art

[0002] Zirconia can be used to make porcelain teeth or all-ceramic teeth, and can also be made into zirconia beads. As a polishing raw material, zirconia beads can polish gold, silver or other metal objects. Zirconia can also be made into artificial gemstones after mixing with other materials, and its specific application scenarios are relatively extensive.

[0003] In the process of manufacturing porcelain teeth or all-ceramic teeth, first, zirconia needs to be pressed into blocks to form disc-shaped zirconia blocks. Then, the zirconia blocks are placed into a cutting device to cut out specific shapes. After taking them out, other processes such as sintering and forming are carried out to complete the production of porcelain teeth or all-ceramic teeth. Before cutting the disc-shaped zirconia blocks, special fixtures are required to fix them.

[0004] Currently, usually, workers manually place zirconia blocks into the fixture and use a screwdriver to install and tighten the fixing screws, so that the zirconia blocks are clamped and fixed. After the cutting action is completed, the fixture is manually loosened with a screwdriver to take out the semi-finished product to be sintered. The entire cutting process is relatively cumbersome, and the entire loading and unloading process completely depends on manual labor, resulting in low cutting efficiency. In addition, during the loading and unloading process, the operator's hands need to reach under the cutting mechanism, which also poses certain safety hazards.

[0056] A rotary table 34 is provided at the central position of the cutting box body 3, and the material clamping mechanism is fixed on the rotary table 34. A material taking station 31, a cutting station 32 and a material discharging station 33 are arranged in the cutting box body 3 along the circumferential direction of the rotary table 34 and directly below the moving path of the material clamping end of the material clamping mechanism.

[0057] The discharging end of the feeding mechanism 4 coincides with the material taking station 31.

[0058] The feeding end of the discharging mechanism coincides with the material discharging station 33.

By providing the guide assembly 45, and the guide assembly 45 and the ejection assembly 44 in this embodiment are respectively located on both sides of the material storage box 41, the ejection plate 444 can be kept in a horizontal state during the rising process, thereby avoiding the problem of material jamming.

[0066] Specifically, in this embodiment, if Figure 2 As shown, the optional feeding mechanism 4 further includes a horizontally arranged feeding channel plate 46, one end of which is arranged close to the top of the material storage box 41, and the other end of which extends into the cutting box 3 and overlaps with the material taking station 31;

After the linear driving structure drives the first clamping arm part and the second clamping arm part to gradually approach, the clamping components 11 of the first clamping arm part and the second clamping arm part will press the disc-shaped material 2 tightly from both sides, so as to realize the automatic fixation of the disc-shaped material 2.
