[0063] In order to make the purpose, technical solutions and advantages of the present application clearer, the present application is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and are not intended to limit the present application. It should be noted that the illustrations provided in the present embodiment only illustrate the basic concept of the present invention in a schematic manner, so the drawings only show components related to the present invention rather than the number, shape and size of components in actual implementation. The form, quantity and proportion of each component in actual implementation can be a random change, and its component layout form may also be more complicated.

[0064] A material bag clamping assembly, see Figure 1 and Figure 2The clamping assembly includes a material bag, a clamping assembly 40 and a pressing assembly 50. The material bag includes a bag opening 10 and a bag body 20. The bag opening 10 is hard and used for discharging materials, and the bag body 20 is soft and used for accommodating materials; the clamping assembly 40 is detachably clamped on the bag opening 10 through an opening and closing structure; one end of the pressing assembly 50 is a pressing end, and the other end is a pressing end. The middle part of the pressing assembly 50 is connected to the clamping assembly 40, and the pressing assembly 50 is detachably connected to the material bag through the clamping assembly 40; by pressing the pressing end, the pressing end can be driven to rotate around the middle part of the pressing assembly 50 and open, and when the pressing end is closed, it is used to press the bag body 20 to form a seal for the material bag when the bag opening 10 is opened.

[0065] The clamping assembly 40 and the clamping assembly 50 are detachable from the material bag, so that the clamping assembly 40 and the clamping assembly 50 can be reused, and the material bag is disposable, which can effectively reduce the use cost of the entire clamping assembly; when in use, the clamping assembly 40 is detachably clamped with the hard bag opening 10, and the clamping assembly 50 is connected to the clamping assembly 40, so that the clamping assembly 40 and the clamping assembly 50 can be removed from the material bag. Since the clamping assembly 50 is provided with a pressing end and a clamping end, the pressing end can be driven to open and close, so that the material bag is sealed when the clamping end is closed, thereby ensuring the sealing of the material inside the material bag; before opening the bag opening 10 of the material bag, the clamping assembly 40 and the clamping assembly 50 are installed on the material bag, the clamping assembly 40 is clamped with the bag opening 10, and the clamping end is pressed against the corresponding position of the bag body 20 The bag is then placed in the bag, and then the bag opening 10 is opened to connect the material bag to the docking machine or other material taking structures. After the docking is completed, the pressing end is pressed to open the pressing end or the clamping assembly 40 and the pressing assembly 50 are removed, or the pressing end is pressed through other structures, so that the docking machine or the material taking structure can discharge the material in the material bag to complete the material transfer. At the same time, it is ensured that the material is always in a sealed state during the period from the opening of the material bag to the docking process, and the material bag can be separated from the discharge connection device of the bag opening 10 after the material taking is completed. During operation, the clamping assembly 40 and the pressing assembly 50 do not come into direct contact with the material, avoiding the problem that the existing material bag adapter is difficult to clean, greatly reducing the use cost, improving the convenience of using the clamping assembly 40 and the pressing assembly 50, and also improving the shelf life of the material, with good protection effect on the material.

[0066] In one embodiment, see Figure 1 and Figure 2 When using the docking machine to export materials, the pressing end can be driven to rotate manually or automatically, so that the clamping end is opened to realize the export of the material in the material bag; the clamping component 40 and the clamping component 50 can also be directly removed so that the material can be freely exported.

[0067] In some embodiments of the present application, see Figure 3 , Figure 4 and Figure 5 The material bag further comprises a cover 30 and a stop spring 11. The cover 30 is threadedly connected to the bag opening 10 and is used to close the material bag. The stop spring 11 is fixed to the bag opening 10 and extends along the outer wall of the bag opening 10. When the stop spring 11 extends and abuts against the inner wall of the cover 30, the cover 30 is pressed by the stop spring 11 and cannot be screwed out of the bag opening 10. When the stop spring 11 is compressed and radially retracted, the cover 30 can be screwed out of the bag opening 10. In this way, by providing the cover 30 and the corresponding stop spring 11, the connection between the cover 30 and the bag opening 10 is made tighter. When the stop spring 11 is not compressed or radially retracted, the stop spring 11 will maintain a radial abutment state with the inner wall of the cover 30, preventing the cover 30 from loosening and falling out or being pulled out.

[0068] In one embodiment, see Figure 3 and Figure 4 The cover 30 is threadedly connected or tightly fitted with the bag opening 10. As long as the tight connection structure between the cover 30 and the bag opening 10 can be guaranteed, the corresponding connection method can be adopted; when the cover 30 is threadedly connected to the bag opening 10, the stop spring 11 abuts against the inner wall of the cover 30, so that the cover 30 cannot be screwed out of the bag opening 10.

[0069] In some embodiments of the present application, see Figure 3 and Figure 4, the width direction of the stop spring piece 11 is parallel to the axial direction of the bag opening 10, a part of the stop spring piece 11 in the width direction is covered by the cover 30, and the other part of the stop spring piece 11 in the width direction extends out of the cover 30 and drives the stop spring piece 11 to retract radially through the closing of the clamping assembly 40; there are at least two stop spring pieces 11 and they are evenly distributed along the outer periphery of the bag opening 10. In this way, the width direction of the stop spring piece 11 is set to be parallel to the axial direction of the bag opening 10, which is convenient for applying force to the stop spring piece 11 and making the stop spring piece 11 retract radially; since the stop spring piece 11 is partially in the area covered by the cover 30, the stop spring piece 11 is partially exposed from the cover 30 and corresponds to the position of the clamping assembly 40, after the clamping assembly 40 is installed on the bag opening 10, the clamping structure of the clamping assembly 40 is closed, and while the clamping assembly 40 and the pressing assembly 50 are connected to the material bag, the stop spring piece 11 is subjected to the clamping assembly. 40's pressure and radially retracts, so that the cover 30 is in an openable state; from this usage, it can be seen that the setting of the stop spring piece 11 has the effect of preventing the cover 30 from being opened before the clamping assembly 40 and the clamping assembly 50 are not installed, and plays an action guiding effect, which can effectively reduce the risk of introducing air caused by misoperation; if the cover 30 is opened before the clamping assembly 40 and the clamping assembly 50 are not installed, the material in the material bag will be in an open state, resulting in the problem that the material cannot be sealed and is easy to be contaminated. The structure of the present application can effectively avoid this situation.

[0070] In one embodiment, the corresponding installation sequence is to install the clamping assembly 40 and the clamping assembly 50 with the material bag, so that the clamping assembly 40 is clamped with the bag opening 10, so that the clamping assembly 50 presses the corresponding position of the bag body 20 and forms a seal with the material in the bag body 20, and then open the bag opening 10. At this time, the material in the bag body 20 will remain sealed under the action of the clamping assembly 50; then dock the bag opening 10 with the docking machine to ensure the sealing of the material during the docking process, and at the same time avoid opening the bag opening 10 before the clamping assembly 40 and the clamping assembly 50 are installed, thereby enhancing the protection of the sealing effect of the material in the material bag.

[0071] In some embodiments of the present application, see Figure 3 The sealing plug 31 is located at the bottom of the sealing plug 30 and is used to clamp with the bag opening 10 and form a sealing structure with the bag opening 10. In this way, the sealing plug 31 is provided so that after the sealing plug 31 is threadedly connected with the bag opening 10, the two form a sealing structure at the bottom of the sealing plug 31, thereby ensuring the sealing of the material inside the bag body 20 after the sealing plug 30 is connected with the bag opening 10.

[0072] In one embodiment, see Figure 3The sealing plug 31 can be cylindrical in shape, and the cylindrical sealing plug 31 is completely inserted into the bag opening 10 and seals the bag opening 10; the sealing plug 31 can be annular in shape, and one end of the annular sealing plug 31 extends into the bag opening 10, and the other end of the annular sealing plug 31 is connected to the bottom of the cover 30, and the thickness of the sealing plug 31 gradually decreases in the direction away from the bottom of the cover 30, so that the sealing plug 31 can be easily inserted into the bag opening 10. At the same time, the sealing plug 31 at the end is thinner to facilitate the deformation of the sealing plug 31, thereby facilitating the deformation of the sealing plug 31 and the insertion of the bag opening 10, so as to ensure the sealing of the material inside the bag body 20 after the cover 30 is connected to the bag opening 10.

[0073] In some embodiments of the present application, see Figure 6 , Figure 7 and Figure 8 The clamping assembly 40 includes a first movable part 41, a second movable part 42 and a connecting shaft 43. The connecting shaft 43 is disposed at one end of the clamping assembly 40. One ends of the first movable part 41 and the second movable part 42 are both rotatably connected through the connecting shaft 43, and the other ends of the first movable part 41 and the second movable part 42 form a detachable clamping structure. In this way, the clamping assembly 40 forms a structure in which one end of the first movable part 41 and the second movable part 42 are hinged around the connecting shaft 43 by providing the first movable part 41 and the second movable part 42 that can rotate relatively, so that the other ends of the first movable part 41 and the second movable part 42 form a detachable structure through the clamping structure, thereby facilitating the connection or disassembly of the clamping assembly 40 and the bag opening 10, and improving the efficiency of disassembly and installation.

[0074] In one embodiment, see Figure 6 When the snap-fit ​​structure is set, the parts where the first movable part 41 and the second movable part 42 form the snap-fit ​​structure are both located at the same end. For example, an L-shaped hook structure is provided at the end of the first movable part 41, and a corresponding buckle is provided at the end of the second movable part 42. The end of the buckle close to the hook structure is an inclined surface and a structure with a reduced thickness is formed on the buckle, thereby facilitating the connection and separation of the buckle and the hook structure.

[0075] In some embodiments of the present application, see Figure 3The material bag also includes a clamping platform 12, which is fixed on the bag opening 10 and radially extends along the outer wall of the bag opening 10; the clamping assembly 40 includes a first air avoidance hole 44 and a second air avoidance hole 45, the first air avoidance hole 44 is located in the middle of the clamping assembly 40 and is used to accommodate the bag opening 10, and the middle parts of the first movable part 41 and the second movable part 42 are both convex semicircular cavity structures; the second air avoidance hole 45 is used for the penetration of the clamping platform 12, and the second air avoidance hole 45 is opened along the length direction of the clamping assembly 40, and the second air avoidance hole 45 is a through hole that penetrates the first movable part 41 and the second movable part 42; wherein, when the clamping assembly 40 is clamped on the clamping platform 12, the clamping platform 12 simultaneously passes through the second air avoidance hole 45 on the first movable part 41 and the second movable part 42. In this way, the corresponding clamping platform 12 and the corresponding second air-avoiding hole 45 are provided, so that when the clamping assembly 40 is fixed on the material bag, the clamping platform 12 can simultaneously pass through the second air-avoiding holes 45 on the first movable part 41 and the second movable part 42, so that when the first movable part 41 and the second movable part 42 are clamped together, the clamping platform 12 is used to facilitate the positioning of the clamping assembly 40 when it is installed on the bag opening 10, and to prevent the clamping assembly 40 from falling off from the bag opening 10. It is also convenient for the clamping assembly 40 to be quickly disassembled from the bag opening 10 when the clamping structure of the first movable part 41 and the second movable part 42 is disassembled. Therefore, the clamping platform 12 and the corresponding second air-avoiding hole 45 structure are provided to achieve rapid positioning of the clamping structure and the bag opening 10 when they are installed, and also ensure rapid disassembly of the clamping structure. The first air-avoiding hole 44 is provided to facilitate the columnar bag opening 10 to extend from the middle of the clamping assembly 40 when the clamping assembly 40 is closed.

[0076] In one embodiment, see Figure 3 The stop spring piece 11 is located above the clamping platform 12. Since the clamping platform 12 is clamped with the second air-avoiding hole 45, part of the clamping assembly 40 is located above the clamping platform 12, and part of the clamping assembly 40 is located below the clamping platform 12. Since the top of the bag opening 10 is used to connect the docking machine and the cover 30, the stop spring piece 11 is arranged above the clamping platform 12, which facilitates the stop spring piece 11 to be partially located in the area covered by the cover 30 and partially located in the area covered by the clamping assembly 40, so that the stop spring piece 11 can be squeezed synchronously after the clamping assembly 40 is installed, so that the stop spring piece 11 is radially retracted, so that the cover 30 can be screwed out.

[0077] In one embodiment, see Figure 3 There is no restriction on the shape of the clamping platform 12. The clamping platform 12 extends radially along the bag opening 10. The edge of the clamping platform 12 can be surrounded by a circular or polygonal structure. The radial dimension of the clamping platform 12 needs to be such that after the clamping assembly 40 is installed, the clamping platform 12 can expose the second air avoidance hole 45, thereby preventing the clamping assembly 40 and the clamping platform 12 from falling out after being clamped.

[0078] In one embodiment, see Figure 6 , Figure 7 and Figure 8 The inner wall of the first air avoidance hole 44 is in shape with the outer wall of the bag opening 10, and a threaded air avoidance groove that is in shape with the external thread of the bag opening 10 can be opened on the inner wall of the first air avoidance hole 44 to improve the tightness of the connection between the first air avoidance hole 44 and the bag opening 10, thereby reducing the shaking of the clamping assembly 40 after installation.

[0079] In some embodiments of the present application, see Figure 6 , Figure 7 and Figure 8 The clamping assembly 40 includes a first connecting rod 46 and a second connecting rod 47. The first connecting rod 46 has at least two rods and extends along the outer wall of the first avoidance hole 44, and the first connecting rod 46 is fixed to the first movable part 41; the second connecting rod 47 has at least two rods and extends along the outer wall of the first avoidance hole 44, and the second connecting rod 47 is fixed to the second movable part 42; wherein, the first connecting rod 46 and the second connecting rod 47 extend in opposite directions, and the two sides of the middle part of the clamping assembly 50 are respectively connected to the first connecting rod 46 and the second connecting rod 47, and the clamping assembly 50 forms a rotatable hinged structure at the connection position. In this way, since the clamping assembly 40 is connected to the clamping assembly 50, and the clamping assembly 50 rotates around the connection position with the clamping assembly 40, the corresponding first connecting rod 46 and the second connecting rod 47 are set on the clamping assembly 40, and the first connecting rod 46 and the second connecting rod 47 are hingedly connected to the clamping assembly 50, so that the clamping assembly 50 can rotate along the hinge with the first connecting rod 46 and the second connecting rod 47 at the same time, thereby opening or closing the clamping end of the clamping assembly 50.

[0080] In some embodiments of the present application, see Fig. 9The clamping assembly 50 includes a pressing piece 51 and a rotating shaft 52. There are two pressing pieces 51, which are symmetrically arranged and form a V-shaped structure. The upper end of the V-shaped structure serves as a pressing end, and the lower end of the V-shaped structure serves as a clamping end. The middle part of the V-shaped structure is connected to the clamping assembly 40; the clamping end is opened by pressing the upper end of the V-shaped structure; there are two rotating shafts 52, which are located in the middle part of the V-shaped structure, and the two pressing pieces 51 are respectively connected to the first connecting rod 46 or the second connecting rod 47 through different rotating shafts 52. In this way, by setting the clamping assembly 50 into a V shape, when the corresponding clamping assembly 50 is installed and not subjected to external force, the clamping end at the lower end of the V shape is in a closed state, and the pressing end at the upper end of the V shape is in an open state; when the pressing end is pressed, the clamping assembly 50 will rotate around the connection position between the middle part of the V shape and the clamping assembly 40, and the clamping end at the lower end of the V shape will be opened; two rotating shafts 52 are set, so that when the clamping assembly 50 is connected to the clamping assembly 40 through the rotating shafts 52, two hinged structures will be formed, thereby facilitating the opening or closing of the clamping structure.

[0081] In one embodiment, after the pressing member 51 is installed and in a relaxed state, the pressing end will keep pressing the material bag. After the rotating shaft 52 connects the pressing member 51 to the clamping assembly 40, the two ends of the rotating shaft 52 are clamped by connecting nuts 56 to prevent the connection structure from falling out.

[0082] In some embodiments of the present application, see Fig. 9 The clamping assembly 50 includes a torsion spring 53, which is clamped on the clamping assembly 40 and the clamping assembly 50 at the same time. The torsion spring 53 is connected to the middle part of the clamping assembly 50, and the clamping assembly 50 can be opened and closed around the torsion spring 53. In this way, by providing the torsion spring 53, the clamping assembly 40 and the clamping assembly 50 form a hinge structure that can rotate relatively. After the position of the clamping assembly 40 is fixed, by providing the torsion spring 53, the clamping assembly 50 can be rotated around the position connected to the clamping assembly 40. Since the clamping assembly 50 is V-shaped, the pressing end of the clamping assembly 50 can be opened or closed by pressing the pressing end.

[0083] In one embodiment, after the clamping assembly 40 and the pressing assembly 50 are installed, during the opening or closing process of the pressing end, the position of the clamping assembly 40 is fixed relative to the position of the material bag, and the pressing assembly 50 rotates relative to the clamping assembly 40. Both the clamping assembly 40 and the pressing assembly 50 are provided with a receiving groove 48, which is used to receive and clamp the torsion spring 53, so that the torsion spring 53 can be clamped on the clamping assembly 40 and the pressing assembly 50 at the same time.

[0084] In some embodiments of the present application, see Figure 1The bag body 20 includes a main accommodating chamber 21 and a narrow liquid passage 22. The main accommodating chamber 21 is used to accommodate materials and is located at the lower part of the bag body 20; the narrow liquid passage 22 is located at the upper part of the bag body 20, and the narrow liquid passage 22 is a long and narrow channel structure. The narrow liquid passage 22 is used to connect the main accommodating chamber 21 and the bag mouth 10; the clamping assembly 50 includes a pressing plate 54 and a sealing strip 55. There are two pressing plates 54 and they are arranged opposite to each other. The pressing plate 54 is located at the clamping end and is used to clamp the narrow liquid passage 22; the sealing strip 55 is deformable and clamps the narrow liquid passage 22, and the sealing strips 55 are connected to the abutting surfaces of the two pressing plates 54 when they are closed. In this way, the bag body 20 is provided with a main containing chamber 21 and a narrow liquid passage 22, so that when the bag body 20 is compressed and sealed by the compression assembly 50, the material can be concentrated in the main containing chamber 21, so that the pressure plate 54 can compress the narrow liquid passage 22 to achieve sealing of the material; the pressure plate 54 is provided to facilitate squeezing the narrow liquid passage 22 to a certain width, thereby improving the sealing effect of the bag body 20; the sealing strip 55 is provided, and the narrow liquid passage 22 is compressed by deformation of the sealing strip 55, thereby ensuring the sealing of the material in the main containing chamber 21.

[0085] In one embodiment, see Figure 3 When the sealing strips 55 on the two pressure plates 54 are set, there are the following situations:

[0086] Only one sealing strip 55 is connected to the pressing plate 54. The sealing strip 55 has at least one sealing strip. The sealing strip 55 can be deformed to a certain extent and press the narrow liquid passage 22 and the other pressing plate 54 to seal. If there are multiple sealing strips 55, the multiple sealing strips 55 can be arranged in parallel.

[0087] Both pressure plates 54 are connected with sealing strips 55, and each pressure plate 54 has at least one sealing strip 55. The sealing strips 55 on the two pressure plates 54 can be arranged relative to each other. When the sealing strips 55 are deformed and have a sealing effect, the sealing strips 55 on the two pressure plates 54 that are opposite to each other can be arranged at positions where they can abut against each other, that is, the abutting structure of the cross section during sealing is, in sequence, the pressure plate 54, the sealing strip 55, the narrow liquid opening 22, the sealing strip 55 and the pressure plate 54; specifically, two sealing strips 55 can be arranged on each pressure plate 54, and the sealing strips 55 form a corresponding structure in which they abut against each other.

[0088] In one embodiment, see Figure 3 The pressing plate 54 is provided with a corresponding installation groove, and the sealing strip 55 is partially located in the installation groove and partially protrudes from the installation groove, so as to ensure that the sealing strip 55 is squeezed and deformed to ensure sealing. The pressing plate 54 can be used as a part of the pressing member 51, or the pressing plate 54 can be used as an independent structure installed on the pressing member 51 through a connecting structure.

[0089] A liquid guiding system includes a material bag clamping assembly, and the system also includes a connector, which is connected to the bag opening 10 and is used to guide the material in the material bag when the pressing end is opened; the pressing end is magnetic, and an electromagnet is provided next to the position where the connector is connected to the bag opening 10, and the pressing end is driven to rotate and the pressing end is opened by energizing the electromagnet.

[0090] In this proposal, see Figure 1 and Figure 2 , by setting the clamping assembly 40 and the pressing structure, the material bag is pressed and sealed, so that when the material bag needs to be docked with the connecting machine, the material bag is first connected with the clamping assembly 40 and the pressing structure, and the pressing structure is used to press the bag body 20 to achieve the sealing of the bag body 20, and then the cover 30 is opened to expose the top of the material bag. At this time, the bag body 20 is sealed with the internal material through the pressing end of the pressing assembly 50; then the connecting machine is docked with the bag opening 10. After the docking is completed, the electromagnet of the connecting machine is energized. Since the pressing end is magnetic, the pressing end of the pressing assembly 50 can be driven by the electromagnet to rotate toward the middle, so that the pressing end of the pressing assembly 50 can be opened. At this time, the connecting machine can export the material in the material bag, thereby achieving the effect of keeping the material sealed during the entire process of taking the material from the material bag. In addition, by setting up an electromagnet, whether the pressing end is in a closed state can be controlled by controlling whether the electromagnet is charged or the magnitude of the charge, thereby controlling the connection or disconnection between the material bag and the connector.
