DETAILED DESCRIPTION

[0021] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0022] like Figures 1 to 7 As shown, the present invention provides a manually operated liquid packaging bag holder, comprising an annular chassis 1 and a bag opening fixing plate 2 arranged above the annular chassis 1, a plurality of support rods 3 are evenly arranged on the annular chassis 1, and the other end of each support rod 3 away from the annular chassis 1 is connected to the bag opening fixing plate 2, the liquid filling port of the packaging bag is fixed by the bag opening fixing plate 2, and the support rod 3 can be a circular tube body or a square tube body.

[0023] A packing bag entry 4 is formed between any two adjacent support rods 3 .

[0024] A packing bag placement groove 5 is formed in the annular chassis 1, and an elastic support net composed of multiple elastic bands 6 is provided on the packing bag placement groove 5. The elastic support net is deformed downward as the weight of the liquid in the packing bag increases.

[0025] The packaging process of this embodiment includes: placing the liquid packaging bag on the packaging bag placement groove 5 through the packaging bag placement port 4, with the bottom of the liquid packaging bag in contact with the elastic support net, and placing the bag opening of the liquid packaging bag on the bag opening fixing plate 2.

[0026] In order to make the packaging bag holder more simple, convenient and easy to use, the support rod 3 in this embodiment is fixedly connected to the annular chassis 1 by metal welding. The angle of the support rod 3 relative to the annular chassis 1 or the angle relative to the horizontal plane needs to be determined according to the actual size of the bag opening of the liquid packaging bag, that is, the size of the bag opening fixing plate 2 is determined.

[0027] Since the liquid filling bag opening of the liquid packaging bag is usually a circular deformable opening, the bag opening fixing plate 2 can specifically be a ring body, and the bag opening of the liquid packaging bag passes from the bottom to the top of the ring body, and then the bag opening is stretched open on the ring body.

[0028] In this embodiment, three support rods 3 are evenly connected to the annular chassis 1. The other ends of the three support rods 3 converge and connect to the bag opening fixing plate 2. The opening of the upper chassis is sized to fit the opening of the liquid packaging bag, allowing it to clamp the liquid packaging bag. A rotatable metal clamping ring is mounted on the upper chassis and can be attracted by a magnet to form a closed packaging bag buckle, preventing the packaging bag from falling under force and effectively preventing liquid leakage. To reduce the manufacturing cost of the bracket, a cross-elastic band can be used on the lower chassis of the bracket. The elastic band effectively holds the liquid packaging bag, providing a fixed and supportive function.

[0029] In this embodiment, if the bag opening of the liquid packaging bag is a fixed ring, then the bag opening needs to be clamped. For this purpose, the bag opening fixing plate 2 includes a plate body 21, and a notch 22 is provided near the edge of the plate body 21 for clamping the bag opening of the packaging bag.

[0030] If the bag opening of the packaging bag is a flexible and deformable structure, a semicircular snap ring 23 is connected to the disc body 21 located at the notch 22, and the two ends of the snap ring 23 are rotatably connected to the corresponding sides of the notch 22. At this time, the inner circle shape of the snap ring 23 is the same as the outer edge shape of the disc body 21.

[0031] If the bag opening of the packing bag is a fixed annular structure, the inner ring shape of the clamping ring 23 is complementary to the notch 22 , and the notch 22 can form a relatively complete circle through the clamping ring 23 to support the bag opening of the packing bag.

[0032] In this embodiment, cylindrical magnets 7 are provided on both ends of the snap ring 23. Mounting holes are provided on the corresponding surfaces of the notch 22 and the ends of the snap ring 23. The snap ring 23 deforms under the action of an external force, allowing the cylindrical magnets 7 to be mounted in the mounting holes. The cylindrical magnets 7 can rotate within the mounting holes. This facilitates the removal and release of the snap ring 23.

[0033] Of course, in this embodiment, the support rod 3 can also be made into a detachable structure, that is, one end of the support rod 3 is detachably connected to the bag opening fixing plate 2, and the other end is fixedly connected to the annular chassis 1. Then, by connecting the support rod 3 and different bag opening fixing plates 2 and the annular chassis 1, it can adapt to packaging bags with different opening sizes and liquid packaging bags with different volumes.

[0034] Therefore, the packing bag holder in this embodiment can be used to obtain various different specifications of packaging at low cost to adapt to various application scenarios, which is flexible and changeable. There is no need to produce a packing bag holder for each different specification of packing bag.

[0035] To this end, quick-release structures 10 are provided at both ends of the support rod 3, a first card slot 8 is provided on the annular chassis 1 to cooperate with the quick-release structure 10 at the top end of the support rod 3, and a second card slot 9 is provided on the disc body 21 to cooperate with the quick-release structure 10 at the bottom end of the support rod 3.

[0036] The second slot 9 is located on the inner surface of the annular chassis 1 and extends from the top to the bottom of the annular chassis 1 .

[0037] When the quick-release structure 10 at the bottom end of the support rod 3 is inserted into the second slot 9, the bottom of the support rod 3 is consistent with the bottom plane of the annular chassis 1, so the force applied to the support rod 3 can be directly transmitted to the ground, and the radial displacement can also be constrained by the annular chassis 1 to ensure the stability of the entire bracket when bearing weight.

[0038] Of course, the first card slot 8 and the second card slot 9 can be a countersunk structure, so as to be a quick-release structure.

[0039] In this embodiment, since different liquid packaging bags need to be packaged with different weights, the elastic support net is provided with a guide groove 31 on the inner surface of the support rod 3 along the length direction of the support rod 3. A guide rod 32 is provided in the guide groove 31. The top end of the guide rod 32 is rotatably connected to a guide block 33. The guide rod 32 can rotate around the guide block 33 as the rotation center to rotate the guide rod 32 out of the guide groove 31. The guide block 33 can move along the guide groove 31.

[0040] A locking structure 11 is provided on the guide block 33 , and the locking structure 11 is used to fix the position of the guide block 33 after it moves in the guide groove 31 .

[0041] The locking structure 11 includes a first through-hole 12 and a second through-hole 13 provided on the guide block 33. The first through-hole 12 is perpendicular to the side walls of the guide slot 31 and extends through the guide block 33. The second through-hole 13 is perpendicular to the bottom wall of the guide slot 31 and extends through the guide block 33. The first through-hole 12 and the second through-hole 13 intersect, dividing the first through-hole 12 into two parts.

[0042] A screw rod 14 is provided in the second through hole 13, and the screw rod 14 is threadedly connected to the second through hole 13. A guide bolt 15 is provided in the two parts of the first through hole 12 separated by the second through hole 13. An inclined wedge mechanism is formed between the inner end of the guide bolt 15 and the screw rod 14. When the screw rod 14 is axially displaced along the second through hole 13, the outer end of the guide bolt 15 protrudes from the surface of the guide block 33 and squeezes and contacts the inner wall of the guide groove 31.

[0043] At the same time, the length of the screw rod 14 can be set so that when the screw rod 14 moves axially along the second through hole 13 and the end thereof approaches the bottom wall of the guide groove 31 , the guide block 33 can also be squeezed and fixed.

[0044] Furthermore, in order to lock the position of the guide block 33 after adjustment in the guide groove 31 , the present embodiment can fix the angle or position of the guide rod 32 rotating around the guide block 33 .

[0045] Specifically, when the screw 14 drives the end of the guide bolt 15 to squeeze and contact the two side walls of the guide groove 31, the guide bolt 15 is moved outward along the axial direction of the first through hole 12 through inclined surface matching (that is, a conical structure 16 is coaxially mounted on the screw 14, and the side surface of the conical structure 16 and the inner end of the guide bolt 15 cooperate to form an inclined wedge mechanism).

[0046] The guide block 33 and the guide groove 31 are locked, and at the same time, the angle of the guide rod 32 after rotating around the guide block 33 can be fixed.

[0047] In specific implementation, it is necessary to symmetrically arrange two connecting plates 34 at the end of the guide rod 32, and the two connecting plates 34 are respectively connected to the guide bolts 15 on the corresponding sides of the first through hole 12. The connecting plates 34 are rotatably connected to the guide bolts 15, that is, the connecting plates 34 and the guide bolts 15 are rotatably connected, and the position of the connecting plates 34 on the guide bolts 15 is fixed.

[0048] When the guide bolt 15 moves axially along the first through hole 12, the connecting piece 34 contacts the side wall of the guide groove 31, thereby fixing the position of the connecting piece 34 by increasing the friction force, and thus the angle of the guide rod 32 can be fixed after adjustment (the guide rod 32 rotates around the guide bolt 15 through the connecting piece 34 or rotates with the guide bolt 15 as the rotation axis).

[0049] Of course, the guide block 33 needs to have a certain degree of deformation ability, that is, it can bend toward the side wall of the guide groove 31. A groove for the displacement of the connecting piece 34 needs to be provided on the side wall of the guide block 33. The groove is open to the side wall surface of the guide groove 31. The groove and the connecting piece 34 cooperate. The connecting piece 34 can be deformed from the groove toward the side wall of the guide groove 31. Part of the guide bolt 15 is exposed in the groove, or the part of the first through hole 12 passing through the groove is exposed.

[0050] The locking structure 11 provided in this embodiment is compact and simple. The position of the guide block 33 in the guide groove 31 can be locked by axial movement of the screw 14 in the second through hole 13, thereby adjusting the height of the guide rod 32 relative to the annular chassis 1 and the angle of the guide rod 32.

[0051] The guide groove 31 in this embodiment can extend to the bottom end of the support rod 3 and be open, and the guide rod 32 is arranged in the guide groove 31 and along the length direction of the guide groove 31. In this way, the height of the guide rod 32 relative to the annular chassis 1 is adjusted, that is, the height of the annular chassis 1 relative to the ground is adjusted to adapt to different discharge port heights. Further, the downward deformation ability of the elastic support net can be improved, that is, the carrying capacity of different liquid packaging bags.

[0052] This embodiment can be explained by taking a specific discharge scenario as an example (the actual use scenario is not limited), for example: for a small-scale manufacturer to produce epoxy resin glue, a 1-ton capacity reactor is used, and there is a discharge port at the bottom of the reactor, and the discharge speed is controlled by a manual valve.

[0053] Below the discharge port, a packaging rack in this embodiment is provided, comprising an open (plastic or stainless steel) funnel, a liquid packaging bag rack, and a liquid bag holder. Liquid bags are placed into the packaging bag rack through a packaging bag inlet 4. An electronic scale is located below the packaging bag rack, and the weight of the bag is determined by tare weighing (excluding the weight of the funnel, rack, and bulk bag) to ensure the accuracy of the bagged material. The use of the packaging bag rack not only saves machinery and equipment costs for small-scale manufacturers but is also highly suitable for low-cost laboratory research. For batch packaging operations, the packaging bag racks can simply be arranged.

[0054] Furthermore, the quick-release structure 10 and the locking structure 11 in this embodiment operate on the same principle (in this case, the second through-hole 9 does not penetrate the guide block 33). Countersunk holes that mate with the locking structure 11 can be provided on the sidewalls of the first and second slots 8, 9, or the working method of existing quick-release structures can be adopted, such as the quick-release structure of the grinding head of a dermabrasion machine. The purpose of the quick-release structure is to quickly connect and disconnect with the first and second slots 8, 9.

[0055] In this embodiment, when the guide rod 32 is provided, the bottom of the support rod 3 is open, allowing the guide rod 32 to extend from the open bottom of the support rod 3, and the quick-release structure 10 is fixedly provided at the bottom of the support rod 3, and the guide groove 31 only extends to the position of the quick-release structure 10.

[0056] The above embodiments are merely exemplary embodiments of the present application and are not intended to limit the scope of the present application. The scope of protection of the present application is defined by the claims. Those skilled in the art may make various modifications or equivalent substitutions to the present application within the essence and scope of protection of the present application, and such modifications or equivalent substitutions shall also be deemed to fall within the scope of protection of the present application.
