For ordinary skilled in the art, the specific meaning of the above terms in the utility model can be understood according to the specific circumstances.

[0027] Figs. 1 to 4The utility model discloses a kind of filling screw cap devices with weighing protection function, and the filling screw cap device with weighing protection function of the embodiment, including the rotary conveying mechanism 1 for conveying container, rotary conveying mechanism 1 week side is equipped with first screw cap station 21 and filling station 31, first screw cap station 21 and filling station 31 correspond and are equipped with first screw cap mechanism 22 and filling mechanism 32, filling station 31 is equipped with weighing sensor 33, weighing sensor 33 is equipped with weighing support 34, weighing support 34 includes mounting base 41 and the contact portion 42 on mounting base 41, rotary conveying mechanism 1 includes carousel 11, for driving carousel 11 rotation rotation drive and for driving carousel 11 lifting lifting drive, carousel 11 is equipped with multiple container placing groove 12, container placing groove 12 below is equipped with bottle support assembly 5, first screw cap station 21 is equipped with height limiting piece 43 for limiting the descending height of bottle support assembly 5, the height of height limiting piece 43 is lower than contact portion 42, higher than mounting base 41.

[0028] The filling screw cap device with weighing protection function fills screw cap process as follows: container is placed in container placing groove 12, and holds container through bottle support assembly 5, rotation drive (not shown in the figure) drives carousel 11 rotation, when container rotates to first screw cap station 21, first screw cap mechanism 22 unscrews the cover of container, facilitates subsequent filling, when container rotates to filling station 31, filling mechanism 32 fills container, needs weighing after filling, when weighing, lifting drive (not shown in the figure) drives carousel 11 to descend, to drive bottle support assembly 5 and container to descend, then container contacts with the contact portion 42 of weighing sensor 33 and limits, bottle support assembly 5 continues to descend, no longer exerts the support force to container, at this time, weighing sensor 33 can be weighed to container after filling through the force transmission action of weighing support 34, since carousel 11 is overall descended, if bottle support assembly 5 continues to descend, possibly collides with the mounting base 41 of weighing sensor 33, exerts a pressure to weighing support 34, influence weighing precision, also possibly damage weighing sensor 33, therefore, height limiting piece 43 is set on first screw cap station 21, wherein the height of height limiting piece 43 is lower than contact portion 42, guarantees that container can fall on contact portion 42 and is weighed, and higher than mounting base 41, guarantees that bottle support assembly 5 will not contact mounting base 41, avoids influence weighing precision and damage weighing sensor 33.

[0029] Further, in the embodiment, the bottle holder assembly 5 comprises a first holder plate 51, a second holder plate 52, and an opening and closing driving mechanism 53 for driving the first holder plate 51 and the second holder plate 52 to relatively approach or move away from each other. When the turntable 11 rotates, the opening and closing driving mechanism 53 drives the first holder plate 51 and the second holder plate 52 to relatively approach each other to clamp the container, so as to avoid the container from moving due to centrifugal force during rotation. When weighing, the opening and closing driving mechanism 53 drives the first holder plate 51 and the second holder plate 52 to slightly move away from each other, so that the holder plate does not interfere with the contact part 42 when descending, and can abut against the height limiting part 43 when continuing to descend. At this time, the first holder plate 51 and the second holder plate 52 only have a supporting effect on the container, and do not have a clamping effect. The turntable 11 descends, and the container falls on the contact part 42. The first holder plate 51 and the second holder plate 52 no longer exert any external force on the container, so as to ensure the accuracy of weighing. The turntable 11 continues to descend, and stops descending when the holder plate on the first cap screwing station 21 abuts against the height limiting part 43, so as to protect the weighing sensor 33. After weighing is completed, the turntable 11 rises to hold the container, and then the opening and closing driving mechanism 53 drives the first holder plate 51 and the second holder plate 52 to relatively approach each other to clamp the container, so as to perform subsequent process steps.

The moving driving assembly 533 is used to drive the bearing portion 531 to move outward. The moving driving assembly 533 drives the bearing portion 531 to move outward, and drives the supporting plates to move away from each other. At this time, the reset spring 532 is compressed, the moving driving assembly 533 moves inward, and the guide sleeve 55 and the supporting plates also move inward under the elastic force of the reset spring 532. At this time, the moving driving assembly 533 plays a certain abutting buffering role, avoiding the supporting plates from being damaged due to the rebounding force.

Thus, the bearing portion 531 can be pushed outward or inward at the same time, and the opening and closing of the supporting plates can be realized.

[0034] Further, in the embodiment, the first supporting plate 51 and the second supporting plate 52 both comprise a bottom supporting plate 56 and a side clamping plate 57 perpendicular to the bottom supporting plate 56. The guide sleeve 55 is connected with the side clamping plate 57, and the side clamping plate 57 is provided with an avoiding groove used to avoid the mounting seat 541 and the guide rod 542. The bottom supporting plate 56 is used to support the bottom of the bottle body, and the side clamping plate 57 is used to clamp the container.
