[0062] Embodiment 1

[0063] This embodiment provides a device for a liquid storage bag to convey liquid, as Figures 1 to 3 shown. The device sequentially includes a frame base 1, a support member 2, and a placement platform 3 from bottom to top; the placement platform 3 is movably fixed on the support member 2 through a movable member 26; a gear transmission device 16 is arranged inside the support member 2, and the gear transmission device 16 is connected to the movable member 26 and used to drive the placement platform 3 to rotate.

[0064] The support member 2 respectively includes a first support member 21 and a second support member 22 connected to both sides of the placement platform 3; the first support member 21 and the second support member 22 are fixedly connected to the frame base 1, and the first support member 21 and the second support member 22 are located on two opposite sides of the edge of the frame base 1.

[0065] The gear transmission device 16 is arranged on one side of the support plate close to the second support member 22; the gear transmission device 16 includes a first gear 17, a second gear 18, and a conveyor belt 19; the first gear 17 and the second gear 18 are connected by the conveyor belt 19; a detachable support plate 20 is arranged outside the first support member 21, and an operation handle 15 is arranged at a position corresponding to the second gear 18 on the side of the support plate away from the second support member 22. The operation handle 15 is fixedly connected to the second gear 18 and used to drive the gear transmission device 16 to rotate; the placement platform 3 is movably connected to the first gear 17 through the movable member 26; the placement platform 3 is movably connected to the second support member 22 at a position opposite to the first gear 17 through the movable member 26.

[0066] In this embodiment, the gear transmission device 16 is movably connected to the storage platform 3. By controlling the gear transmission device 16, the rotation of the storage platform 3 is realized, and thus the hanging angle of the liquid storage bag on the storage platform 3 is controlled. The force required for rotation is not large, and only one operator is needed to rotate the operating handle. Before the liquid medicine is pre-filtered, only one operator is needed to fix the liquid storage bag on the storage platform 3 of the device. After the liquid medicine is filtered into the liquid storage bag, only one operator needs to operate the handle to rotate the storage platform 3 in real time, and then the operation of injecting the liquid medicine into the filling glass dispenser can be completed. The filling efficiency is relatively high, and it is more labor-saving, safe and convenient. Moreover, the detachable support plate 20 arranged outside the first support member 21 can, on the one hand, prevent the operator from directly contacting the gear transmission device 16, improving the safety of device operation; on the other hand, when the gear transmission device 16 is damaged, such as problems like gear rusting and conveyor belt 19 jamming, it is convenient to disassemble and repair.

[0067] The storage platform 3 includes a platform bottom plate 10, a baffle 11 and a hanging member 9; the hanging member 9 is arranged at the middle position of one side of the storage platform 3 perpendicular to the first support member 21; the baffle 11 includes first baffles 12 arranged on both sides of one side of the storage platform 3 parallel to the first support member 21 and a second baffle 13 on one side opposite to the hanging member 9; a groove 14 is arranged in the middle of the second baffle 13.

[0068] In this embodiment, the storage platform 3 is used to place the liquid storage bag, which can be laid flat on the platform bottom plate 10 to complete the pre-filtration of the liquid medicine; or its angle can be adjusted at any time until the liquid storage bag is vertically suspended to complete the filling. Further, the first baffle 12, the second baffle 13 and their grooves 14 are arranged to assist in supporting the hanging liquid storage bag to a certain extent, prevent it from falling, and improve the operation safety; making it more convenient and fast for the operator to take the liquid or fill the liquid.

[0069] The device further includes a moving member 5 arranged at the bottom of the frame base 1; the moving member 5 includes rollers. The frame base 1 includes a bottom plate 7, a layer of partition plate 8 and enclosing plates 6 arranged on both sides of the partition plate 8, and the plane where the enclosing plates 6 are located is parallel to the plane where the support member 2 is located; the partition plate 8 is arranged parallel to the bottom plate 7, and the bottom plate 7 is perpendicular to the enclosing plates 6.

[0070] In this embodiment, the moving member 5 arranged at the bottom of the frame base 1 enables the operator to move the position of the device as needed at any time, and it is not necessary for multiple operators to complete the movement of the device. Moreover, the arrangement of the partition plate 8 can be used to store items, reducing the time for the operator to go back and forth to get the required items, being more time-saving and labor-saving, and meeting the actual application requirements.

[0071] The device further includes a gantry 4 connected to the support member 2; the gantry 4 includes a cross beam 25, a first connecting member 23, and a second connecting member 24; the top ends of the first connecting member 23 and the second connecting member 24 are connected by the cross beam 25; one end of the first connecting member 23 opposite to the top end is connected to the first support member 212; the first connecting member 23 is parallel to the first support member 21; one end of the second connecting member 24 opposite to the top end is connected to the second support member 22; the second connecting member 24 is parallel to the second support member 22 and their central axes overlap; the second connecting member 24 and the second support member 22 are integrally formed parts.

[0072] In this embodiment, the gantry 4 in the device can, on the one hand, serve as a handle when the device is moved, and on the other hand, be used to support the storage platform 3, with a certain load-bearing function, making the device more stable when moving.

[0073] In this embodiment, the direction in which the hanging member 9 points to the groove 14 is defined as the x-direction for the device, and the rotation angle range of the storage platform 3 from the horizontal position to the x-direction is 0 to 90°; the overall length, width, and height dimensions of the device are 800mm * 800mm * 2000mm.

[0074] Embodiment 2

[0075] This embodiment provides a device for a liquid storage bag to convey liquid. Except that the frame base 1 of the device includes three layers of partitions 8, the rest of the structure is the same as that in Embodiment 1.

[0076] The device provided in this embodiment can also store a large number of operating supplies compared with Embodiment 1, improving the space utilization rate of the device.

[0077] Embodiment 3

[0078] This embodiment provides a device for a liquid storage bag to convey liquid. Except that a detachable support plate 20 is not arranged outside the first support member 21, the rest are the same as those in Embodiment 1.

[0079] The device provided in this embodiment can still realize the rotation of the storage platform 3, realize the real-time adjustment of the hanging angle of the liquid storage bag, and improve the filling efficiency. However, since the detachable support plate 20 is not arranged outside the first support member 21 in the device provided in this embodiment, the gear transmission device 16 is exposed, which is easy to be damaged and dangerous, and the safety performance of the device is poor.

[0080] Embodiment 4

[0081] This embodiment provides a device for a liquid storage bag to convey liquid. Except that the baffle 11 is not arranged on the storage platform 3, the rest are the same as those in Embodiment 1.

[0082] Compared with Embodiment 1, the liquid storage bag on the storage platform 3 of the device provided in this embodiment is suspended in the air without the auxiliary support of the baffle 11, resulting in the risk of falling due to the heavy weight of the liquid storage bag.

[0083] Comparative Example 1

[0084] This comparative example provides a device for a liquid storage bag to convey liquid. Except for not providing the gear transmission device 16, the rest of the device is the same as that in Embodiment 1.

[0085] Since the device provided in this comparative example lacks the gear transmission device 16 to regulate the rotation of the storage platform 3, there is only a fixed hanging angle for the liquid storage bag on the storage platform 3, which cannot meet the requirement of quickly completing the filling of a relatively large and heavy liquid storage bag. There is still a need for 4 to 6 operators to lift and tilt the operation, which is time-consuming and laborious, and the safety is poor.

[0086] In summary, the present invention provides a device for a liquid storage bag to convey liquid. The device is connected to the storage platform by setting a gear transmission device to drive the rotation of the storage platform, so as to adjust the hanging angle of the liquid storage bag on the storage platform in real time. Before the pre-filtration of the liquid medicine, only 1 operator is required to lay and fix the liquid storage bag on the storage platform for pre-filtration. After the liquid medicine is filtered into the liquid storage bag, only 1 operator can complete the adjustment of the hanging angle of the liquid storage bag until the liquid medicine is successfully filled, without the need for 4 to 6 operators to perform the lifting and tilting operations, improving the filling efficiency, reducing the labor and operation time, and the operation is safe. Moreover, the device further sets at least one layer of partition on the frame base and a moving part at the bottom, and further sets a baffle on the storage platform and a gantry, further improving the mobility, space utilization rate and safety of the device.

[0087] The applicant declares that the present invention uses the above embodiments to illustrate the detailed structural features of the present invention, but the present invention is not limited to the above detailed structural features, that is, it does not mean that the present invention must rely on the above detailed structural features to be implemented. Those skilled in the art should understand that any improvement to the present invention, the equivalent replacement of the components selected by the present invention, the addition of auxiliary components, and the selection of specific methods, etc., all fall within the protection scope and the disclosure scope of the present invention.
