Description

Technical Field

[0001] This utility model relates to the field of zirconia ceramic block technology, specifically a weighing device for processing high-precision zirconia ceramic blocks. Background Technology

[0002] Zirconia ceramic blocks are high-performance ceramic materials widely used in dental restorations, precision instrument manufacturing, and industrial applications, possessing excellent mechanical strength, wear resistance, and biocompatibility. In the processing of zirconia ceramic blocks, accurate weighing of raw materials is a crucial step in ensuring product quality. Current zirconia ceramic block processing typically uses ordinary electronic weighing devices to weigh the powdered raw materials, which are then transported to mixing equipment for further processing.

[0003] However, existing weighing instruments have several problems during use: Firstly, ordinary weighing instruments lack specific protective measures, making them susceptible to interference from external airflow and dust during the weighing process, leading to a decrease in weighing accuracy. Secondly, during use, operators need to frequently open the protective cover to add materials, and the connection structure between the protective cover and the weighing instrument is not robust enough, easily becoming loose and affecting the accuracy of the weighing data. Furthermore, the protective structure design of existing weighing instruments is unreasonable; operators need to fully open the protective cover when adding materials, increasing the interference of external factors on the weighing process and reducing work efficiency.

[0004] Therefore, there is an urgent need for a high-precision weighing device specifically designed for the processing of zirconia ceramic blocks. This weighing device should have a reasonable protective structure to effectively isolate external interference, as well as a stable locking mechanism to ensure the accuracy and stability of the weighing process, and to improve the convenience of material addition and work efficiency.

[0046] Please see Figure 1-6 This utility model provides a technical solution: a high-precision weighing device for processing zirconia ceramic blocks, comprising:

[0047] Weighing device 1;

[0048] The material loading platform 2 is set on the weighing device 1;

[0049] Protective mechanism 3 is installed on the weighing device 1. Protective mechanism 3 is suitable for protecting the material loading platform 2. Protective mechanism 3 includes:

[0050] An acrylic protective cover 31 is connected to the top of the weighing device 1 and is installed on the outside of the material loading platform 2.

[0051] The top cover 32 is fixedly connected to the top inner wall of the acrylic protective cover 31, and a feeding port 321 is provided inside the top cover 32;

[0052] Baffle 33 is connected to top cover 32;

[0053] The knob 34 is fixedly connected to the top of the baffle 33 and passes through the top of the top cover 32;

[0054] A locking mechanism 4 is provided between the protective mechanism 3 and the weighing device 1. The locking mechanism 4 is suitable for fixing the acrylic protective cover 31 to the weighing device 1.

[0055] Specifically, the structural design of the protective mechanism 3 effectively isolates the weighing device from external interference factors such as airflow and dust during use, ensuring the stability of the weighing environment. The acrylic protective cover 31 is made of transparent material, allowing operators to clearly observe the weighing process. The feeding port 321 on the top cover 32, combined with the design of the baffle 33, allows operators to add materials without fully opening the protective cover, reducing interference from external factors. The knob 34 makes the operation of the baffle 33 more convenient. The locking mechanism 4 ensures the stability of the connection between the acrylic protective cover 31 and the weighing device 1, avoiding weighing errors caused by the loosening of the protective cover during the weighing process. This structural combination effectively improves the accuracy and ease of operation of raw material weighing during the processing of zirconia ceramic blocks, solving the technical problems of insufficient protection and inconvenient operation of existing weighing devices.

[0056] Reference manual attached Figure 3-4 The top cover 32 has a movable channel 322 in its center, which connects to the feeding port 321. A baffle 33 moves within both the feeding port 321 and the movable channel 322, with its height matching the height of the movable channel 322. Specifically, this forms a compact and easy-to-operate feeding mechanism. This design allows the baffle 33 to rotate smoothly within the movable channel 322 without jamming or wobbling during adjustment, ensuring precise control of the opening and closing of the feeding port 321. Because the height of the baffle 33 matches the height of the movable channel 322, it prevents the baffle 33 from wobbling up and down during rotation, further improving operational stability. This structural design not only improves the convenience and accuracy of material addition but also effectively reduces potential disturbances during the weighing process, ensuring the accuracy of weighing data. It also improves work efficiency and solves the technical problem of existing weighing devices requiring the complete opening of the protective cover during material addition, which affects weighing accuracy.

[0057] Reference manual attached Figure 3-4Both the baffle 33 and the feed port 321 have a fan-shaped structure, with the central arc angle of the feed port 321 being smaller than that of the baffle 33. Specifically, the baffle 33 can rotate smoothly under the control of the knob 34, achieving precise blocking or opening of the feed port 321. Because the central arc angle of the feed port 321 is smaller than that of the baffle 33, it ensures that the baffle 33 can completely cover the feed port 321, preventing external dust, airflow, etc., from entering the protected area through the feed port 321 during the weighing process and affecting the weighing accuracy. At the same time, the operator can control the rotation angle of the baffle 33 by rotating the knob 34 according to actual needs, adjusting the opening size of the feed port 321 to adapt to the material addition requirements of different volumes and quantities, enhancing the flexibility of use. This fan-shaped structure design is not only simple in structure and convenient in operation, but also effectively solves the technical problems of insufficient protection and inconvenient operation during the material addition process of existing weighing instruments, improving the accuracy and work efficiency of the weighing process.

[0058] Reference manual attached Figure 6 The locking mechanism 4 includes:

[0059] Insert 41 is fixedly connected to the outer surface of acrylic protective cover 31;

[0060] Card holder 42 is fixedly connected to the top of the material carrier 2, and insert block 41 is connected to the inside of card holder 42;

[0061] Locking rod 43 is movably connected to insert block 41 and card slot 42;

[0062] Pull block 44 is fixedly connected to one end of locking rod 43;

[0063] Spring 45 is fixedly connected between pull block 44 and card holder 42.

[0064] Specifically, a locking mechanism 4, comprising a plug 41, a mounting base 42, a locking rod 43, a pull block 44, and a spring 45, achieves a stable connection between the acrylic protective cover 31 and the weighing device 1. The plug 41 is fixedly connected to the outer surface of the acrylic protective cover 31, and the mounting base 42 is fixedly connected to the top of the loading platform 2. The plug 41 is connected to the inner side of the mounting base 42. This design establishes a preliminary positioning between the acrylic protective cover 31 and the weighing device 1. The locking rod 43 is movably connected to the plug 41 and the mounting base 42, and its insertion locks the plug 41 and the mounting base 42. The pull block 44 is fixedly connected to one end of the locking rod 43, facilitating the operator to pull the locking rod 43. The spring 45 is fixedly connected between the pull block 44 and the mounting base 42, ensuring that the locking rod 43 automatically resets after release, maintaining the locked state. This multi-component collaborative locking mechanism design is not only simple in structure and easy to operate, but also has a firm and reliable connection, which improves the accuracy and stability of raw material weighing during the processing of zirconia ceramic blocks.

[0065] The mounting base 42 has a "C" shape, and the width of the insert 41 matches the inner width of the mounting base 42. Specifically, the "C"-shaped mounting base 42 provides a three-sided spatial constraint for the insert 41, enhancing connection stability and reducing the possibility of the insert 41 wobbling within the mounting base 42. The precise match between the width of the insert 41 and the inner width of the mounting base 42 ensures a tight fit of the insert 41 within the mounting base 42, eliminating connection gaps and improving the rigidity and stability of the overall structure. This design makes the connection between the acrylic protective cover 31 and the weighing device 1 more robust and reliable, effectively avoiding weighing errors caused by loosening of the protective cover during the weighing process.

[0066] Reference manual attached Figure 5-6 Both the insert block 41 and the card holder 42 have horizontally through-holes for locking, and the locking rod 43 is fitted through and connected to the locking holes with a clearance fit. Specifically, the horizontally through-hole design allows the locking rod 43 to pass smoothly through the insert block 41 and the card holder 42 to form a mechanical lock; the clearance fit design between the locking rod 43 and the locking hole ensures that the locking rod 43 can be smoothly inserted and withdrawn, and also ensures stability in the locked state.

[0067] Before use, the operator first needs to install the protective mechanism 3 onto the weighing device 1 using the locking mechanism 4. The operator holds the acrylic protective cover 31 and aligns the plug 41 fixedly connected to its outer surface with the "C"-shaped bracket 42 fixedly connected to the top of the loading platform 2. The operator pulls the locking rod 43 by pulling the pull block 44, causing the locking rod 43 to disengage from the center of the bracket 42. At this time, the spring 45 is in a stretched state. Then, the plug 41 is inserted into the inside of the bracket 42. Since the width of the plug 41 matches the width of the inside of the bracket 42, the plug 41 can be accurately positioned and firmly embedded. After the plug 41 is fully inserted into the inside of the bracket 42, the operator aligns the plug 41 with the horizontally through-hole in the bracket 42 and releases the pull block 44. Under the elastic force of the spring 45, the locking rod 43 automatically passes through the locking hole, forming a mechanical lock, thereby firmly connecting the acrylic protective cover 31 to the weighing device 1. When it is necessary to disassemble the protective mechanism 3, first pull the pull block 44 to make the locking rod 43 exit the locking hole, and then take out the acrylic protective cover 31 from the card seat 42.

[0068] Before weighing, the baffle 33 completely covers the feed port 321 on the top cover 32, forming a closed environment. When adding zirconia raw material, the operator turns the knob 34, causing the baffle 33, which is fixedly connected to it, to rotate within the movable channel 322 of the top cover 32. The operator can precisely adjust the opening size of the feed port 321 by controlling the rotation angle of the knob 34. After the material is added, the knob 34 is turned again to make the baffle 33 completely cover the feed port 321, restoring the airtightness of the weighing environment. At this time, the weighing device 1 accurately weighs the zirconia raw material on the loading platform 2 while isolating external interference. Throughout the process, because the acrylic protective cover 31 is firmly connected to the weighing device 1, and the opening and closing of the feed port 321 is precisely controlled by the baffle 33, the influence of external airflow, dust and other interference factors on the weighing accuracy is effectively reduced, improving the accuracy of raw material weighing and the convenience of operation during the processing of zirconia ceramic blocks.

[0069] 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.
