The support member 3 is connected to the end of the mounting member 1, and the containing member 8 is movably connected to the support member 3 through a connecting member 5, so as to support the connecting member 5 and the containing member 8.

[0029] The support member 3 is located in the middle of the end of the mounting member 1, and a guide surface 4 is provided on the support member 3 to ensure that the ultrafine calcium carbonate dropped onto the support member 3 can slide down to the containing part 8 inside the mounting member 1;

The power component 11 is movably connected to the first piece 91 and the second piece 92 through a pull wire, and is used to pull the two pieces to move, so that the ultrafine calcium carbonate on the two pieces falls and reaches the strip packaging bag below. The first piece 91 and the second piece 92 are both movably connected to the main body of the placement piece 9 through a torsion spring and a connecting shaft, and are used to support the first piece 91 and the second piece 92 so that they are placed horizontally; when the pull wire of the power component 11 is released, the first piece 91 and the second piece 92 can be driven to reset.

[0033] The guide surface 4 is symmetrical about the middle of the support member 3 , and the guide surface 4 is an inclined surface, which is used to ensure that the ultrafine calcium carbonate dropped onto the support member 3 can slide down to the containing part 8 inside the mounting member 1 .

[0036] The connecting member 5 is connected to the middle part of the supporting member 3 and the containing part 8, and the connecting member 5 includes an elastic element 6 and a protective member 7; the elastic element 6 is used to pull the containing part 8, and the protective member 7 is used to prevent the ultrafine calcium carbonate from reaching the middle member 93 and the elastic element 6, so that the fallen ultrafine calcium carbonate reaches the first member 91 and the second member 92.

[0037] The elastic element 6 is located between two protective members 7 . The elastic element 6 is specifically a spring and is used to detect the total mass of the ultrafine calcium carbonate on the containing part 8 . The protective member 7 is specifically an accordion cover.

[0038] The detection member 2 is specifically a proximity switch, which is used to detect whether the containing component 8 is close to each other, thereby obtaining the total mass of the containing component 8 and the ultrafine calcium carbonate thereon, and at the same time detecting whether the containing component 8 is reset. The number of the detection members 2 is not less than one, and the detection surface of the detection member 2 faces the containing component 8.

[0039] The first piece 91 and the second piece 92 are symmetrical with respect to the middle piece 93 . The power assembly 11 includes a cylinder and a push plate 12 . The cylinder body of the cylinder is fixedly connected to the middle piece 93 .

[0040] The first piece 91 and the second piece 92 are both provided with a pull ring 94 , and the push plate 12 is provided with a connecting portion.

[0041] The pull ring 94 on the first piece 91 and the pull ring 94 on the second piece 92 are symmetrical about the cylinder, and the pull ring 94 is connected to the connecting part through a pull wire, which is used to ensure that the power component 11 can drive the first piece 91 and the second piece 92 to rotate through the pull wire, so that the ultra-fine calcium carbonate thereon falls off.

[0042] The working principle of the utility model is as follows: before using an elastic ultrafine calcium carbonate packaging weight detection mechanism, an elastic ultrafine calcium carbonate packaging weight detection mechanism is installed on the packaging equipment, that is, the mounting member 1 of the elastic ultrafine calcium carbonate packaging weight detection mechanism is connected to the feeding pipe of the packaging equipment, at this time, the containing member 8 is located directly below the feeding pipe of the packaging equipment and above the sealing member of the packaging equipment, and then the packaging bag of the packaging equipment is pulled out from the upper part of the feeding pipe until the mounting member 1 covers the sealing member of the packaging equipment; when using an elastic ultrafine calcium carbonate packaging weight detection mechanism, the mounting member 1 is connected to the feeding pipe of the packaging equipment, and the containing member 8 is located directly below the feeding pipe of the packaging equipment and above the sealing member of the packaging equipment, and then the packaging bag of the packaging equipment is pulled out from the upper part of the feeding pipe until the mounting member 1 covers the sealing member of the packaging equipment; When the ultrafine calcium carbonate packaging weight detection mechanism is used: the feeding pipe of the packaging equipment supplies a certain amount of ultrafine calcium carbonate to the containing part 8 at a uniform speed. In this process, the ultrafine calcium carbonate reaches the containing part 8 through the guide surface 4 of the mounting part 1 and the supporting part 3. In this process, the ultrafine calcium carbonate on the containing part 8 increases, thereby increasing the pulling force of the containing part 8 on the connecting part 5. In this process, the containing part 8 slowly moves away from the supporting part 3. As the containing part 8 slowly moves away from the supporting part 3 until the detection part 2 detects the signal of the containing part 8, it is proved that the amount of ultrafine calcium carbonate on the containing part 8 is When the weight approaches the required weight, the detection member 2 transmits the detection signal to the external control system; under the control of the external control system, the feeding pipe of the packaging equipment stops supplying ultrafine calcium carbonate to the containing part 8, and the remaining ultrafine calcium carbonate in the mounting member 1 that is descending all falls onto the containing part 8. Further, under the control of the external control system, the power assembly 11 works, and in this process, the cylinder pulls the pull ring 94 on the first member 91 and the second member 92 through the push plate 12 and the pull wire, so that the first member 91 and the second member 92 overcome the pulling force of the torsion spring and rotate, and in this process, the ultrafine calcium carbonate on the containing part 8 falls off. The packaging bag falls into the packaging bag at the sealing component, and then the sealing component of the packaging equipment works to cut and seal the strip packaging bag, and then the packaging bag feeding mechanism of the packaging equipment works to drive the packaging bag to continue to descend for a distance. During this process, the cylinder drives the push plate 12 to reset, and the first piece 91 and the second piece 92 are reset under the action of the torsion spring. At the same time, the containing component 8 is reset to approach the supporting component 3 under the action of the connecting component 5, and the reset signal is detected by the detection component 2. When the containing component 8 is reset, the packaging equipment provides ultrafine calcium carbonate again under the control of the external control system; the above steps are repeated until the work is completed.
