[0042] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0043] As 1 and Figure 2 As shown, the utility model provides a bag retaining frame, including a bag opening retaining platform 101 and a bottom supporting platform 102 , a retaining opening 3 for constraining the bag opening shape is formed on the bag opening retaining platform 101 , and the opening direction of the retaining opening 3 faces the bottom supporting platform 102 .

[0044] The bottom support 102 is used to support the bottom of the medicine bag 2 and keep the bag opening of the medicine bag 2 in the retaining opening 3 , and a space for the medicine bag 2 to expand is formed between the bag opening retaining platform 101 and the bottom support 102 .

[0045] When in use, firstly, the external mouth opener is placed into the holding opening 3, and then the top of the medicine bag 2 is placed into the bag holder 1 from the bottom support 102, and the opening of the medicine bag 2 is made to enter the holding opening 3 from the lower side of the holding opening 3, so that the opening of the medicine bag 2 is opened by the mouth opener in the holding opening 3, and after the medicine bag 2 is opened by the mouth opener, the opening of the medicine bag 2 is closely attached to the inner wall of the holding opening 3, thereby achieving the purpose of supporting the opening of the outer surface of the medicine bag 2 (the deformation state of the medicine bag is as shown in FIG. Figure 4 as shown).

[0046] Then the mouth-opening device is separated from the medicine bag 2, and the material discharge device injects the material into the medicine bag 2.

[0047] From the above process, it can be seen that the mouth opener does not contact the material, and the medicine bag 2 is retained by the retaining opening 3, which can avoid the risk of cross contamination between the retaining component 1 of the medicine bag 2 and the material, and can stably maintain the opening state of the medicine bag 2.

[0048] In this embodiment, the medicine bag 11 generally refers to: a paper medicine bag or an aluminum-plastic film medicine bag, and its material is generally required to have a certain ability to maintain shape (hardness), and the specific type is not limited.

[0049] In a preferred embodiment, the inner circumference of the opening 3 is kept equal to the outer circumference of the bag mouth of the medicine bag 2, and the inner circumference of the opening 3 is kept slightly larger, so that the state of the bag mouth can be maintained more stably, which can generally be 0 to 4 mm, but is not limited thereto.

[0050] Reference Figure 1 and Figure 5 As shown, the cross-section of the opening 3 is preferably set to a spindle shape, which is characterized in that the spindle-shaped structure has at least two corner ends, that is, two overlapping corner structures are formed after the bag mouth of the medicine bag 2 is opened, so that the bag mouth of the medicine bag 2 can better constrain itself according to the material characteristics to maintain the bag mouth shape.

[0051] Reference Figure 5 As shown, limiting grooves 301 are provided on the side walls of the two opposite corner ends of the spindle-shaped retaining opening 3, so that the medicine bag 2 is overlapped to form a corner edge portion 201 and is limited in the limiting grooves 301, that is, the two corner edges 201 of the medicine bag 2 are further limited by the limiting grooves 301 at the two corner ends of the retaining opening 3, so as to further limit the position of the bag opening of the medicine bag 2, so that the bag opening of the medicine bag 2 maintains a spindle-shaped opening state. The friction between the corner edges of the medicine bag 2 in the limiting grooves 301 can also prevent the medicine bag 2 from escaping from the limiting grooves 301 upwards to a certain extent.

[0052] In order to ensure that the medicine bag 2 cannot be separated from the limiting groove 301 upward, refer to Figure 1 and Figure 3 As shown, a limit stopper 5 is provided on the side of the retaining opening 3 of the bag opening retaining platform 101, and the limit stopper 5 blocks the opening of the limit groove 301 in the direction of the opening to limit the medicine bag 2 from escaping from the retaining opening 3 to the outside.

[0053] When the medicine bag 2 enters the retaining opening 3 from below the retaining opening 3, the top of the medicine bag 2 abuts against the lower end surface of the limit block 5 to block the upper end surface of the high bag opening retaining platform 101 of the medicine bag 2. Furthermore, the limit block 5 is arranged above the limit groove 301 to further limit the corner 201 of the medicine bag 2.

[0054] In order to facilitate the removal of the medicine bag 2 after filling, refer to Figure 1 , Figure 3 and Figure 5 As shown, one end of the bag mouth holding platform 101 is connected to one end of the bottom supporting platform 102 via a connecting plate 103, and the other end of the bag mouth holding platform 101 and the other end of the bottom supporting platform 102 are open.

[0055] A lateral opening 6 is provided on the bag opening holding platform 101 from the holding opening 3 to the opening direction, so that the user can take out the medicine bag 2 through the limiting groove 301 and the lateral opening 6 after the medicine bag 2 is filled with materials.

[0056] The lateral opening 6 and the limiting groove 301 are arranged in a staggered manner to prevent the corner 201 of the medicine bag 2 from entering the opening 6 after the medicine bag 2 is held in the opening 3 .

[0057] A further preferred embodiment is as follows: Figure 1 , Figure 3 and Figure 6 As shown, a groove 401 for limiting the bottom of the medicine bag 2 is opened on the bottom support 102, and the bottom of the groove 401 is a supporting plate 4, and the end of the groove 401 in the opening direction of the lateral opening 6 is an open structure to allow the medicine bag 2 to slide out.

[0058] In actual application, since it is not convenient to insert medicine bags into the top and sides of the medicine bag rack, an open groove 402 is set on the support plate 4 from the inner open structure to penetrate the open structure. The open groove 402 is used to place the medicine bags, so that the medicine bags can be inserted from the bottom without hindrance.

[0059] Preferably, the opening slot 402 is configured to be in a curved shape (eg, an S-shaped shape) so that after the medicine bag is opened, the curved opening slot 402 prevents the bottom of the medicine bag from entering, thereby avoiding the problem of the medicine bag being stuck in the opening slot 402 .

[0060] Based on the design of the above-mentioned bag holding frame, the utility model further provides the following specific embodiments to form a multi-station bag holding device.

[0061] Cylindrical bag holding device: see Figure 7 and Figure 8 As shown, the above-mentioned bag holders are assembled, and multiple bag holders are connected by a central column 7 and combined into a cylindrical structure to achieve the support of multiple medicine bags 2 in a limited space, with a small size and easy operation.

[0062] Furthermore, in the circular retaining component assembly, the circular retaining component assembly is driven to rotate, so as to facilitate the bagging of each retaining opening and the filling of materials.

[0063] Long bag holding device: refer to Fig.11 As shown, the above-mentioned bag holders are assembled, and multiple bag holders are connected as a whole through a linear body 8, which drives linear movement, thereby realizing long-distance transmission of the medicine bag 2 and multi-station operation, thereby improving the efficiency of the medicine bag 2 opening and filling.

[0064] Rotating bag holding device: refer to Fig. 9 and Fig.10 As shown, the above-mentioned bag holders are assembled, and multiple bag holders are connected as a whole through a rotating body 9, which drives the rotating body to reciprocate, thereby realizing long-distance reciprocating transmission of the medicine bag 2 and multi-station operation, thereby improving the efficiency of the medicine bag 2 opening and filling.
