Description
Technical Field
[0001] This utility model relates to the field of zirconia ceramic block technology, specifically a zirconia ceramic block processing and sealing machine. Background Technology
[0002] Currently, in the field of dental restorative materials, zirconia ceramic blocks are widely used in the fabrication of crowns, bridges, and implant abutments due to their excellent mechanical properties, biocompatibility, and aesthetics. During the processing of zirconia ceramic blocks, to maintain their integrity and prevent contamination, they are typically sealed in plastic packaging. Existing zirconia ceramic block sealing technologies mostly employ manual operation or simple semi-automated equipment. This involves placing the ceramic block between two layers of plastic film and then sealing it with heat to form a sealed bag, thus protecting the ceramic block for storage and transportation.
[0003] However, existing zirconia block encapsulation equipment generally suffers from problems such as cumbersome operation, low efficiency, and simple equipment structure. Traditional encapsulation methods often require operators to repeatedly perform steps such as feeding, positioning, and heat sealing, resulting in high labor intensity and difficulty in guaranteeing heat sealing quality. At the same time, existing equipment generally lacks a reasonable buffer protection mechanism, which can easily damage the ceramic blocks during the heat sealing process.
[0004] Therefore, there is an urgent need for a zirconia block processing and sealing machine with a reasonable structure and simple operation, which can improve production efficiency while ensuring sealing quality and better meet the development needs of the modern dental material processing industry.

Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.
[0038] Please see Figure 1-7 This utility model provides a technical solution: a zirconia ceramic block processing and sealing machine, comprising:
[0039] Frame 1, with a turntable motor 3 installed on the inner side of frame 1;
[0040] Turntable 2 is set on the top of frame 1. Turntable 2 is fixedly connected to the motor shaft of turntable motor 3. Several sets of mounting slots 6 are opened in a regular ring array on turntable 2. Material box 7 is connected to the mounting slot 6. Lower plastic film 8 is connected to the material box 7.
[0041] The upright frame 4 is fixed to the top of the frame 1. An assembly box 5 is fixedly connected to the front side of the upright frame 4. A plastic sealing cylinder 9 is installed inside the assembly box 5. A heat sealing component is connected to the output end of the plastic sealing cylinder 9. Four sets of guide rollers 15 and two sets of film coating rollers 16 are fixedly connected to the front side of the upright frame 4 in a regular matrix. An upper film 17 is wound on the film coating rollers 16 and the guide rollers 15. A limit handle 18 is installed on the film coating rollers 16 by bolts.
[0042] The heat-sealing assembly is suitable for heat-sealing the upper film 17 onto the lower plastic film 8.
[0043] Specifically, the coating roller 16 and the guide roller 15 are both mounted on the stand 4 via a fixed shaft, and the limit handle 18 is a detachable design.
[0044] Reference manual attached Figure 2 The heat-sealing components include:
[0045] Intermediate body 10 is fixedly connected to the output end of the plastic-sealed cylinder 9;
[0046] The upper fixing ring 11 is fixed to the outer side of the upper end of the intermediate body 10;
[0047] The lower movable ring 12 is connected to the lower end of the intermediate body 10, and the intermediate body 10 is movably inserted through the inner side of the lower movable ring 12.
[0048] Several sets of positioning rods 13 are fixedly connected to the top of the lower movable ring 12 in a regular circular array, and the upper end of the positioning rods 13 is inserted into the upper fixed ring 11 with a gap fit.
[0049] The electric heating plate 20 is fixedly connected to the bottom of the lower movable ring 12.
[0050] Specifically, the heat-sealing assembly is fixedly connected to the output end of the sealing cylinder 9, forming a precise and controllable pressure transmission system. The upper end of the intermediate body 10 is fixedly connected to the upper fixed ring 11, and the lower end of the intermediate body 10 is movably connected to the lower movable ring 12. A guiding structure is formed through the positioning rod 13, ensuring a stable and precise motion trajectory during the heat-sealing process. The electrothermal pressing plate 20 directly contacts the upper coating film 17 during the heat-sealing process and provides heat and pressure.
[0051] The heat-sealing assembly also includes:
[0052] Several sets of springs 14 are fixedly connected in a regular circular array between the upper fixed ring 11 and the lower movable ring 12, and several sets of positioning rods 13 are respectively inserted inside the several sets of springs 14.
[0053] Specifically, spring 14 forms a highly efficient buffer protection system. When the heat-sealing assembly moves downward under the drive of the sealing cylinder 9, spring 14 can effectively buffer the impact force, avoiding rigid contact between the heating plate 20 and the material carrier box 7. At the same time, the setting of spring 14 also makes the heat-sealing pressure more evenly distributed, ensuring the heat-sealing quality between the upper film 17 and the lower plastic film 8. In addition, the elasticity of spring 14 allows the heat-sealing assembly to automatically rebound after heat sealing, facilitating the lifting of the heat-sealing assembly and the rotation of the turntable 2, improving the operating efficiency and automation level of the equipment.
[0054] Reference manual attached Figure 4-5 The material container 7 includes a cup body 701 and an upper edge 702. The upper edge 702 is integrally connected to the outer upper end of the cup body 701, and a plurality of annular grooves 19 are formed in the top of the upper edge 702. Specifically, the outer diameter of the middle part of the cup body 701 is adapted to the inner diameter of the mounting slot 6. The cup body 701 is used to stably place itself in the mounting slot 6. The annular grooves 19 formed in the top of the upper edge 702 create a specific heat-sealing contact area, ensuring sealing performance during the heat-sealing process.
[0055] Reference manual attached Figure 6 The bottom of the heating plate 20 is integrally connected with several sets of annular protrusions 21. The material carrier 7 rotates to correspond vertically with the position of the heating plate 20, and the several sets of annular protrusions 21 are adapted to and connected to several sets of annular grooves 19 through lifting and lowering movements. Specifically, when the turntable 2 rotates to position the material carrier 7 directly below the heating plate 20, the sealing cylinder 9 drives the heat sealing assembly to descend, so that the annular protrusions 21 are precisely embedded in the annular grooves 19, forming a closed heat sealing pressure area. This "protrusion-groove" corresponding design firstly achieves the concentration of heat sealing pressure, so that heat and pressure are mainly concentrated at the contact point between the upper film 17 and the lower plastic film 8 that need to be sealed, improving heat sealing efficiency and quality; secondly, the precise fit between the annular protrusions 21 and the annular grooves 19 forms multiple sealing lines, so that even if a single sealing line has a minor defect, the multiple sealing structure can still ensure the overall sealing performance; thirdly, this structural design can also prevent the film from wrinkling or shifting during the heat sealing process, ensuring the flat and beautiful appearance of the plastic seal.
[0056] Reference manual attached Figure 1One end of the upper coating film 17 is connected to one set of coating rollers 16. After passing through four sets of guide rollers 15, the upper coating film 17 is connected to another set of coating rollers 16. The bottom of the upper coating film 17 is horizontally positioned between the heating plate 20 and the material box 7. Specifically, multi-point guiding control achieves a balanced distribution of film tension. The two sets of coating rollers 16, together with the limit handle 18, allow the operator to adjust the tightness and feed amount of the upper coating film 17 according to actual needs. This effectively solves the problems of easy wrinkling, displacement, or uneven tension of film in traditional plastic sealing equipment. At the same time, this design also facilitates the replacement and adjustment of the upper coating film 17, improving the convenience of equipment maintenance and work efficiency.
[0057] When using the equipment, first ensure that the heating platen 20 reaches the preset temperature. At the same time, check whether the upper film 17 is correctly installed between the film coating roller 16 and the guide roller 15, and adjust the limit handle 18 to control the film tension. During operation, place the lower plastic film 8 and the zirconia ceramic block in the material box 7 in sequence, and then drive the turntable 2 to rotate through the turntable motor 3 to accurately position the material box 7 at the heat sealing station. After the sealing cylinder 9 is activated, the intermediate body 10 drives the entire heat-sealing assembly to descend. When the bottom of the heating plate 20 presses the upper cover film 17 and the lower plastic film 8 onto the upper edge 702, the spring 14 begins to act as a buffer. The intermediate body 10 continues to descend a distance through the lower movable ring 12 and the heating plate 20. At the same time, the annular protrusion 21 at the bottom of the heating plate 20 precisely aligns with the annular groove 19 on the upper edge 702 of the carrier box 7. Under the combined action of heat and pressure, the upper cover film 17 and the lower plastic film 8 fuse and seal at the contact area, forming a sealed bag that completely encapsulates the ceramic block. After heat sealing is completed, the sealing cylinder 9 retracts, and the heat-sealing assembly rises back to its initial position under the rebound force of the spring 14. The turntable 2 rotates again to remove the sealed product and transport the next carrier box 7 to be sealed to the workstation. Overall, the structural design of this heat-sealing component greatly improves the accuracy and reliability of the molding process, ensures the consistency of the molding quality of zirconia blocks, and extends the product's shelf life.
[0058] As an additional note, the lower part of the lower plastic film 8 is box-shaped to accommodate the ceramic block, while the upper part has a ring-shaped structure for heat-sealing connection with the upper film 17. The overall shape of the lower plastic film 8 matches the shape of the material carrier box 7. The shape of the lower plastic film 8 can be prefabricated; please refer to the attached instruction manual. Figure 7The upper film 17 is specially designed with equally spaced release holes, which facilitates the precise separation of a circular plastic piece from the upper film 17 during stamping, serving as the "lid" of the sealed bag. During operation, the zirconia ceramic block is carefully placed on the box section of the lower plastic film 8. When the heat-sealing assembly operates, under the combined action of heat and pressure, the annular portion of the upper film 17 and the lower plastic film 8 fuse and seal at the contact area. Simultaneously, the release holes on the upper film 17 form a predetermined release line, creating a packaging structure that is both tightly sealed and easy to open later. The zirconia ceramic block is completely encapsulated in a sealed container composed of the box section of the lower plastic film 8 and the circular "lid" section of the upper film 17.
[0059] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
