Description

Technical Field

[0002] Nano calcium carbonate is a calcium carbonate material with a special particle size. It has the characteristics of fine particles, large specific surface area and high surface activation rate. The production process of nano calcium carbonate mainly includes carbonization method, double decomposition method, jacketed reactor method, emulsion method and electrochemical method. It is widely used in the plastic industry, ink products and rubber, coatings, chemical building materials, adhesives and sealants and other industries. It plays an important role in many fields and is one of the indispensable high-performance inorganic materials in modern industry. It needs to be weighed to measure its data during the production process.

[0003] At present, most of the existing weighing devices have a relatively simple structure. When a large amount of calcium carbonate needs to be weighed, the existing devices cannot be adjusted according to the corresponding amount. Personnel may need to use multiple weighing devices to share the weighing or weigh only a portion of the calcium carbonate at a time, which makes the weighing process time-consuming and labor-intensive, and also increases a certain amount of use cost, resulting in a decrease in the practicality of the device. Therefore, we propose a nano calcium carbonate weighing device to solve the above problems. Utility Model Content

[0025] Furthermore, the lifting assembly includes a connecting plate 3 arranged on one side of the weighing box 1, and the connecting plate 3 is U-shaped, and a motor 5 is fixedly installed on the top of the connecting plate 3 through a bracket, and the output end of the motor 5 is driven and connected to a screw rod 4, and the bottom end of the screw rod 4 passes through the upper side wall of the connecting plate 3 and is rotatably connected to the top of the lower side wall. A screw sleeve 6 is sleeved on the outside of the screw rod 4, and one side of the outer ring of the screw sleeve 6 is fixedly connected to the adjacent side wall of the first baffle plate 7 through a connecting block. Specifically, through the setting of the screw sleeve 6, by starting the motor 5 to drive the screw 4 to rotate, the screw sleeve 6 is vertically displaced along the guide rod, and the screw sleeve 6 then drives the first baffle plate 7 and the second baffle plate 8 to displace together through the connecting block, so that the first baffle plate 7 and the second baffle plate 8 are lifted and lowered and can resist the calcium carbonate loaded on the top of the weighing box 1, so as to avoid the situation where the calcium carbonate is vibrated and falls during the weighing process to affect the weighing data effect, thereby improving the practicability of the device.

[0026] Furthermore, the positioning component includes a mounting shell 11 arranged on one side of the weighing box 1, one side of the mounting shell 11 is open, and one side surface of the mounting shell 11 located at the opening is fixedly connected to the side wall of the weighing box 1, a limiting plate 13 is provided inside the mounting shell 11, one side of the limiting plate 13 is fixedly connected to an insert block 12 plugged into the jack and the slot, and the other side of the limiting plate 13 is fixedly connected to a pull rod 15, and one end of the pull rod 15 away from the limiting plate 13 passes through the side wall of the mounting shell 11 and is fixedly connected to the pull block.

When weighing, the second baffle 8 is moved to separate the two magnetic blocks 10.

[0029] Furthermore, a guide rod is provided inside the screw sleeve 6 and on one side of the screw rod 4, and the two ends of the guide rod are respectively fixedly connected to the sides of the two end walls of the connecting plate 3 that are close to each other.

[0031] When weighing, by holding the pull block and pulling the pull rod 15, the limit plate 13 is driven to move so that the plug block 12 is separated from one of the sockets and the slot to release the positioning of the expansion plate 2. At this time, the limit plate 13 moves to squeeze the spring 14, and the personnel pulls out the expansion plate 2 to expand the top space of the weighing box 1, and then releases the pull block to make the spring 14 lose the squeezing force and elastically push the limit plate 13 back to its position.
