Description

Technical Field

[0001] The utility model relates to a multi-axis synchronous rotating cover opening structure. Background Art

[0002] In the IVD (in vitro diagnostic product) industry and the biopharmaceutical field, a standard boxed tubular packaging material is often used, usually with 24-96 or even more packaging materials per box. This packaging material is generally sealed by a screw-threaded cap, which is unscrewed for filling and then tightened when completed.

[0003] In order to improve operational efficiency, automated equipment is usually used to remove and cap the entire box of packaging materials at the same time, which requires that such equipment can achieve synchronous rotation when screwing the cap.

[0004] Currently, most of this type of equipment on the market is driven by multiple motors to rotate simultaneously, but this solution has the problems of complex structure and high cost. Therefore, a multi-axis synchronous rotation opening structure is proposed to solve the above problems. Utility Model Content

[0013] Preferably, the eccentric distances of the active eccentric shaft and the rotary cover eccentric shaft are completely equal.

[0015] Preferably, the drive plate is located between the rotating shaft mounting plate and the power element mounting plate.

[0025] The present invention will be further described below with reference to the accompanying drawings.

[0026] like Figure 1-4 The structure shown in FIG. 1 shows a multi-axis synchronous rotary capping mechanism, comprising multiple capping eccentric shafts 1, a support assembly, a rotating assembly, and a drive assembly. The multiple capping eccentric shafts 1 are rotatably connected to the support assembly, the upper end of which is connected to the drive assembly, the output end of which is connected to the rotating assembly, and the rotating assembly is connected to the multiple capping eccentric shafts 1. The number of capping eccentric shafts 1 can be increased or decreased as needed. In the embodiment, the number of rotating eccentric shafts is 24, and this number can be expanded to 48 or 96.

[0027] like Figure 2 As shown, the bracket assembly includes a rotating shaft mounting plate 2, four support columns 4 and a power element mounting plate 6. The upper end surface of the rotating shaft mounting plate 2 is connected to the four support columns 4, and the upper ends of the four support columns 4 are connected to the power element mounting plate 6; a plurality of first mounting holes 8 are opened on the rotating shaft mounting plate 2, and a plurality of rotary cover eccentric shafts 1 are rotatably connected in the first mounting holes 8; the upper end of the rotary cover eccentric shaft 1 passes through the first mounting hole 8 to connect the rotating assembly.

[0028] like Figure 2 As shown, the rotating assembly includes a drive plate 3, which is located between the rotating shaft mounting plate 2 and the power element mounting plate 6. The drive plate 3 is provided with multiple second mounting holes 9, into which the upper end of the eccentric shaft 1 of the rotary cap is fixedly connected. A third mounting hole 10 is provided in the middle of the upper end surface of the drive plate 3, into which the lower end of the active eccentric shaft 5 is rotatably connected, and the upper end of the active eccentric shaft 5 is connected to the driving assembly. The spacing between the multiple first mounting holes 8 on the rotating shaft mounting plate 2 is exactly the same as the spacing between the multiple second mounting holes 9 on the drive plate 3. The eccentric distances of the eccentric shafts of the active eccentric shaft 5 and the eccentric shaft 1 of the rotary cap are exactly the same.

[0029] like Figure 2As shown, the drive assembly includes a rotary power source 7 mounted on a power element mounting plate 6. The output end of the rotary power source 7 is fixedly connected to the upper end of the active eccentric shaft 5. The rotary power source 7 is a motor. Rotation of the rotary power source 7 drives the active eccentric shaft 5 to rotate about the rotary power source's rotation axis. Rotation of the short shaft on the eccentric shaft 5 connected to the drive plate rotates the drive plate 3, thereby simultaneously driving all the capping eccentric shafts 1 to rotate about the capping axis simultaneously and in the same direction, thereby achieving synchronous rotational power during capping.

[0030] like Figure 2 As shown, the rotation axes of all the eccentric shafts 1 of the rotary caps are parallel to each other, and all the eccentric shafts 1 of the rotary caps are fixed in the first mounting hole 8 on the rotary shaft mounting plate 2, and can freely rotate around the axis of each eccentric shaft 1 of the rotary caps, and cannot move axially. The rotary shaft mounting plate 2 is fixedly connected to the power element mounting plate 6 through the support column 4 and keeps the position unchanged, providing support for other parts. The rotary power source 7 is installed on the power element mounting plate 6, and the active eccentric shaft 5 is connected to the power source rotating shaft to drive it to rotate around the power source rotating axis. One side of the drive plate 3 is connected to the output eccentric end of the active eccentric shaft 5, and the other side is connected to the driving end of all the eccentric shafts 1 of the rotary caps. The rotary power source 7 can drive the active eccentric shaft 5 to rotate forward and reverse, and the active eccentric shaft 5 can drive the porous drive plate 3 to rotate around the rotary power source drive axis, and the porous drive plate 3 can drive all the eccentric shafts 1 of the rotary caps to rotate around the rotary cap axis.

[0031] The multi-axis synchronous rotary lid opening structure drives the active eccentric shaft 5 to rotate by rotating the rotary power source 7, and the rotation of the eccentric shaft 5 drives the porous driving plate 3 to rotate, thereby simultaneously driving all the rotary lid eccentric shafts 1 to rotate simultaneously and in the same direction, thereby obtaining synchronous rotary power when screwing the lid. The rotation direction of the rotary lid shaft can be changed by changing the rotation direction of the power source; only one rotary power drive is used to make multiple parallel shafts rotate simultaneously and synchronously and switch directions; the structure is simple and the cost is low.

[0032] like Figure 5 As shown, the number of the rotating power source 7 and the active eccentric shaft 5 can be four, and the four rotating power sources 7 are respectively installed at the four corners of the power element mounting plate 6, and the output end is respectively connected to an active eccentric shaft 5, and the lower ends of the four active eccentric shafts 5 are respectively rotatably connected to the four corners of the upper end surface of the driving plate 3. The rotation of the rotating power source 7 drives the driving plate 3 to rotate, and the execution power is stronger.
