DETAILED DESCRIPTION

[0059] The present application will be further described in detail below with reference to the accompanying drawings.

[0060] The present embodiment is only an explanation of the present application, and is not a limitation of the present application. Those skilled in the art can make modifications to the present embodiment without creative contribution, as long as the modifications are within the scope of the claims of the present application.

[0061] The process design of the present application will be realized in the form of cooperation of box body design, equipment design and action design.

[0062] The present scheme relates to the inner liner bag 2, the packaging box 1, the ton bag feeding device 3 and the logistics conveying system 4.

[0063] Referring to Figure 1 , the inner liner bag 2 is provided with four openings 21 equidistantly arranged near the upper side, and a sealing ring is added inside the openings 21 to increase the strength. The inner liner bag 2 is provided with a filling port 22 at the top side. When the four openings 21 are hung and the whole inner liner bag 2 is fully stretched, the filling port 22 is located directly above the inner liner bag 2.

[0064] Referring to Figures 2-20 , the packaging box 1 comprises a box body 11, a box cover 12, a base frame 13, a fixing strap 14, a hook 15 and a cover plate 16.

[0065] The box body 11 has a containing cavity for placing the inner liner bag 2. The box cover 12 is placed on the upper side of the box body 11 for covering the box body 11. The bottom frame 13 is arranged on the lower side of the box body 11 for bearing the box body 11. The upper end surface of the box cover 12 is provided with a plurality of recessed areas 121. The lower end surface of the bottom frame 13 downwardly extends and is provided with a plurality of supporting legs 131 corresponding to the recessed areas 121.

[0066] The box body 11 plays a role of supporting the inner liner bag 2 from four sides, effectively preventing the inner liner bag 2 from toppling. In addition, the bottom frame 13 can be stacked on the upper side of the box cover 12 of another packaging box 1 through the cooperation of the supporting legs 131 and the recessed areas 121, realizing the stacking of a plurality of packaging boxes 1, thereby containing more inner liner bags 2 filled with powder in a unit area, and further containing more powder. The cooperation of the recessed areas 121 and the supporting legs 131 makes the bottom frame 13 not slide relative to the box cover 12 on the lower side, and is safer when stacked.

[0067] The bottom of the box body 11 is provided with a material leakage hole a. The inner liner bag 2 placed in the box body 11 can also be broken by a bag breaking head. The bag breaking head passes through the material leakage hole a from bottom to top, directly acts on the inner liner bag 2, and will not damage the box body 11.

[0068] The box body 11 comprises four side plates 111 arranged around and a bottom plate 112 arranged on the bottom side of the side plates 111 and forming a containing cavity for placing the inner liner bag 2 together with the side plates 111. The side plates 111 are rotationally assembled on the upper side of the bottom plate 112. When stored, the plurality of side plates 111 are respectively folded inwardly to greatly reduce the occupied space of the box body 11.

[0069] The four side plates 111 are respectively a first side plate 111a, a second side plate 111b and a fourth side plate 111d adjacent to the first side plate 111a, and a third side plate 111c opposite to the first side plate 111a. Each of the first side plate 111a close to the second side plate 111b on one side and close to the fourth side plate 111d on the other side, and the third side plate 111c close to the second side plate 111b on one side and close to the fourth side plate 111d on the other side is provided with a through channel 1111 from top to bottom. The packaging box 1 further comprises four fixing bands 14. Each of the fixing bands 14 passes through one of the through channels 1111. The lower end of the fixing band 14 is fixed in the bottom plate 112, and the upper end of the fixing band 14 extends out of the upper side of the through channel 1111 and forms a ring or a hook for hanging the box body 11.

[0070] By setting the fixed band 14, and the fixed band 14 through the passage 1111 of the side plate 111, one end is fixed in the bottom plate 112, the other end extends on the upper side of the passage 1111 and forms a ring or hook, so that the box 11 is hung by the fixed band 14, the fixed band 14 is directly transmitted to the bottom plate 112 by gravity, only the strength of the fixed band 14 and the bottom plate 112 is tested, and because the lower end of the fixed band 14 is directly fixed in the bottom plate 112 rather than the upper side of the bottom plate 112, the strength of the connection is greater, so that the high strength packaging box 1 is not easy to separate from the hanging when hoisting.

[0071] The four side plates 111 together form a rectangular frame. In this embodiment, the four side plates 111 form a rectangular box with a square cross section. The bottom plate 112 has a bottom plate wall around the bottom plate body in addition to the bottom plate body; the side plate 111 is rotatably mounted on the bottom plate wall.

[0072] The bottom plate 112 has a horizontal reinforcing rib 1124 inside and below the first side plate 111a and the third side plate 111c, and the lower end of the fixed band 14 is fixed to the end side of the reinforcing rib 1124. Take the first side plate 111a as an example, the lower end of the two fixed bands 14 on it is fixed to the two ends of the reinforcing rib 1124 respectively, keeping balance, which is also the reason why two passages 1111 are provided on two of the four side plates 111. In addition, the reinforcing rib 1124 is preferably a steel bar, which has sufficient strength.

[0073] Specifically, the lower end of the fixed band 14 is sleeve-shaped and sleeved on the end side of the reinforcing rib 1124. The inside of the bottom plate 112 corresponding to the first side plate 111a and the third side plate 111c is originally a cavity, which is filled after the fixed band 14 is sleeved, so as to fix the lower end of the fixed band 14 in the bottom plate 112.

[0074] The packaging box 1 also includes a plurality of flaps 113 arranged in the receiving cavity and located on the bottom plate 112. The middle part of the bottom plate 112 and the flaps 113 are provided with a material leakage hole a. The side of the flap 113 away from the material leakage hole a is a free end, and when the free end is lifted, the flap 113 forms a landslide inclined towards the material leakage hole a.

[0075] By setting multiple flip plates 113 on the bottom plate 112, the multiple flip plates 113 can be gathered together by lifting the flip plates 113 away from one side of the material leakage hole a, forming a landslide guiding the material leakage hole a, which helps to fully and quickly discharge the powder in the inner liner bag 2; when the flip plate 113 is in a flat state, the inner liner bag 2 can be accommodated in the accommodation cavity, so that the packaging box 1 can accommodate the inner liner bag 2 containing more powder, and when the powder in the inner liner bag 2 is partially discharged, the flip plate 113 is lifted to form a landslide to further discharge the powder.

[0076] The bottom plate 112 is provided with a top plate hole 1121 corresponding to each flip plate 113, and the top plate hole 1121 is located on the side of the bottom plate 112 away from the rotating shaft. Specifically, in this embodiment, the bottom plate 112 is provided with 2N top plate holes 1121, and each flip plate 113 corresponds to two top plate holes 1121. During operation, multiple external jacks pass through the top plate holes 1121 from bottom to top and continue to jack up upwardly, thereby lifting the free end of each flip plate 113 upwardly, and further gathering the multiple flip plates 113 together to form a landslide guiding the material leakage hole a. After the external jacks retract, they no longer support the flip plates 113, and the flip plates 113 no longer gather together but fall back onto the bottom plate 112.

[0077] The inner bottom wall of the bottom plate 112 is provided with multiple grooves 1122 communicating with the material leakage hole a, and each groove 1122 is provided with a flip plate 113; when the flip plate 113 is flat, the flip plate 113 is flush with the groove 1122. That is, the inner bottom wall of the bottom plate 112 is provided with multiple convex edges 1123, each of which extends from the inner side wall of the bottom plate 112 to the material leakage hole a, and the adjacent convex edges 1123 form the above-mentioned grooves 1122. When the flip plate 113 is flat, the flip plate 113 is flush with the convex edge 1123, forming a plane, so that the inner liner bag 2 can be better placed, and the powder in the inner liner bag 2 will not be left on the inner bottom wall due to the unevenness of the inner bottom wall of the bottom plate 112.

[0078] The outer contour of the inner bottom wall of the bottom plate 112 is also square. A groove 1122 is provided between each side of the inner bottom wall of the bottom plate 112 and the material leakage hole a; when the four flip plates 113 are lifted, they collectively form the gathering cavity b.

[0079] The packaging box 1 further comprises multiple hooks 15 provided on the inner wall of the box body 11 and close to the upper side, for hooking the inner liner bag 2. Since the inner wall of the box body 11 is provided with multiple hooks 15, the lifting straps or lifting rings of the inner liner bag 2 can be hung thereon to support the inner liner bag 2.

[0080] The inner wall of the box 11 is provided with a hook 15 placement groove 1112 on the upper side, and the hook 15 can be accommodated in the hook 15 placement groove 1112. The design of the hidden hook 15 makes the hook 15 hidden in the hook 15 placement groove 1112, and does not scratch the inner liner bag 2 when the inner liner bag 2 is put in. When the inner liner bag 2 needs to be opened, the hook 15 is taken out, and the handle of the inner liner bag 2 is hung on the hook 15. Preferably, the hook 15 is accommodated to fill the hook 15 placement groove 1112, so that the inner wall of the box 11 is smooth. The hidden hook 15 has various forms, and two schemes are listed below for description.

[0081] In this embodiment, four hook placement grooves 1112 are arranged on the inner wall of the box 11 near the top corner, and each hook placement groove 1112 is provided with a hook 15.

[0082] The packaging box 1 further comprises a cover plate 16 slidably assembled on the outer bottom side of the box 11, for opening or closing the material leakage hole a. That is, the cover plate 16 is slid to open or close the material leakage hole a. More specifically, the cover plate 16 comprises a first cover plate 161 slidably assembled on the outer bottom side of the box 11, and a second cover plate 162 slidably assembled on the outer bottom side of the box 11. The first cover plate 161 and the second cover plate 162 move towards or away from each other to close or open the material leakage hole a. Of course, the user can also slide one of the cover plates 16 to semi-close the material leakage hole a, and adjust the discharging speed.

[0083] The cover plate 16 is provided with a convex column 163 protruding downward away from the box 11, which facilitates sliding of the cover plate 16. The user can operate the convex column 163 to slide the cover plate 16, which is more convenient than directly sliding the cover plate 16. Each cover plate 16 is provided with two convex columns 163.

[0084] The bottom frame 13 is provided with a bottom frame material leakage avoiding hole 132 corresponding to the material leakage hole a, and a top plate avoiding hole 133 corresponding to the top plate hole 1121.

[0110] By arranging the packaging box 1 for placing the inner liner bag 2, when the inner liner bag 2 filled with powder is placed in the packaging box 1, the packaging box 1 supports the inner liner bag 2 from all sides to effectively prevent the inner liner bag 2 from toppling; in addition, the bag breaking head is always rotating during the operation of the ton bag feeding device 3 to prevent the powder from being blocked, thereby improving the powder feeding efficiency; at the same time, the vibration device 38 of the ton bag feeding device 3 makes intermittent vibration to shake the powder in the inner liner bag 2 in the packaging box 1 to fall, thereby further improving the powder feeding efficiency; during the discharging process, the top plate device 37 of the ton bag feeding device 3 makes intermittent lifting movement to drive the flap 113 of the packaging box 1 to make intermittent turning movement, so that the multiple flaps 113 are gathered together to form a landslide guiding the leakage hole a of the packaging box 1, which helps the powder in the inner liner bag 2 to be fully and quickly discharged, thereby further improving the powder feeding efficiency.

[0111] Specifically, referring to Figure 24 , the step S1 includes the following steps:

[0112] S11, hanging the inner liner bag 2 on the hook 15 of the packaging box 1;

[0113] S12, filling the powder into the inner liner bag 2 through the filling port 22 of the inner liner bag 2;

[0114] S13, transporting the packaging box 1 to the transport carrier 41 and conveying to the feeding port 45;

[0115] S14, the transport carrier 41 places the packaging box 1 on the conveyor 42 at the feeding port 45;

[0116] S15, after the packaging box 1 is lifted by the elevator 43, it enters the conveying line 47 and is sent to above the receiving port of the ton bag feeding device 3 in the feeding area 48.

[0117] As a preferred solution, in step S13, the box cover 12 is first covered; then the packaging box 1 is carried onto the transport carrier 41, and the packaging box 1 is stacked on the transport carrier 41 in at least two layers. Compared with the ton bag being placed on the transport carrier 41 in one layer, the use of the present transport method can stack the inner liner bags 2 filled with powder through the packaging box 1, so that more powder can be transported at one time during transportation.

[0118] Specifically, referring to Figure 25 , step S2 includes the following steps:

[0119] S21, the packaging box 1 is positioned by the positioning device 32 and locked by the locking device 33;

[0120] S22, the cover plate 16 of the packaging box 1 is opened, and the receiving port cover plate is opened;

[0121] S23, the receiving port is raised and engaged with the material leakage hole a of the packaging box 1.

[0122] Before the receiving port is engaged with the material leakage hole a of the packaging box 1, the packaging box 1 is first positioned by the positioning device 32, and then locked by the locking device 33, which improves the docking accuracy of the receiving port and the material leakage hole a, and also prevents the receiving port and the material leakage hole a from deviating during the material feeding process.

[0123] In addition, since the packaging box 1 is provided with the cover plate 16 for opening or closing the material leakage hole a, the cover plate 16 can be controlled to close the material leakage hole a when the powder is fed to the specified weight, so as to realize quantitative feeding. The cover plate 16 also plays a role in protecting the inner liner bag 2 when it is closed. The receiving port cover plate is provided at the receiving port, which is opened during work and closed during non-use, so as to prevent dust and the like from falling into the receiving port, and also effectively protect the broken bag head lamp in the receiving port.

[0124] Since the receiving port is raised and engaged with the material leakage hole a of the packaging box 1 in step S23, the receiving port needs to be reset in step S4.

[0125] Step S21 specifically includes: after the packaging box 1 is moved to above the receiving port by the moving mechanism, the positioning device 32 is used to position the box body 11; after positioning, the moving mechanism is lowered to place the packaging box 1 on the positioning device 32; the moving mechanism is moved to a standby position; and then the locking device 33 locks the packaging box 1 on the ton bag feeding device 3. The positioning device 32 used in the present solution includes four edge-arranged corner guards for positioning the outer shape of the packaging box 1. The locking device 33 used in the present solution includes two oppositely arranged box pushing plates, and the lower side of the box pushing plate is provided with a box pushing plate moving mechanism for driving the horizontal movement of the box pushing plate. When locking, the box pushing plate moving mechanism drives the box pushing plate to move horizontally inward to clamp the packaging box 1.

[0126] Step S22 is specifically: the receiving plate mechanism 361 pulls open the cover plate 16 at the bottom of the packaging box 1; the opening plate mechanism pulls open the receiving port cover plate.

[0127] More specifically, the receiving plate mechanism 361 includes: a pulling plate and a pulling plate moving mechanism. The pulling plate is sleeved on the convex column 163 of the packaging box 1, and the pulling plate moving mechanism moves horizontally to the outside to pull open the cover plate 16, exposing the material leakage hole a of the packaging box 1. The opening plate mechanism includes: a receiving port cover plate and a receiving port cover plate moving mechanism. The receiving port cover plate moving mechanism drives the receiving port cover plate to move outward along the horizontal direction to expose the receiving port of the ton bag feeding device 3.

[0128] Using the present feeding method, the whole process is automatically operated, and the feeding efficiency is greatly improved.

[0131] S2, the receiving port of the ton bag feeding device 3 is engaged with the material leakage hole a of the packaging box 1;

[0132] S3, when the powder is put into the specified weight or all is put in or reaches the specified time, the sound and light prompt the end of the feeding work, the bag breaking device 35 of the ton bag feeding device 3 starts, the bag breaking head rotates upward, pierces the inner liner bag 2, and then starts to discharge; during the discharging process, the bag breaking head is always rotating to prevent the powder from being blocked, and at the same time, the vibration device 38 of the ton bag feeding device 3 starts to vibrate intermittently; during the discharging process, the top plate device 37 of the ton bag feeding device 3 makes intermittent lifting motion to drive the intermittent overturning motion of the turning plate 113 of the packaging box 1;

[0133] S4, the bag breaking head descends and stops rotating; the top plate device 37 resets; the vibration device 38 stops vibrating;

[0134] S5, when the packaging box 1 is completely discharged, the empty box is returned to the conveying line 47 and then conveyed to the elevator 43 and lowered to the conveyor 42 at the discharge port 46; when the packaging box 1 is put into the specified amount of powder, the packaging box 1 containing the remaining powder is returned to the conveying line 47 for cyclic buffering until the feeding is completed;

[0135] S6, the empty box is picked up by the transport carrier 41 at the conveyor 42 at the discharge port 46 and returned.

[0136] In step S5, the weight of the powder put in can be measured by a metering device, and when the powder is put in to the specified weight, the mechanisms are reset, and the packaging box 1 containing the remaining powder returns to the conveying line 47 for cyclic buffering until the feeding is completed.

[0137] The packaging box 1 in the scheme is provided with four fixed bands, so that the packaging box 1 can be hoisted by hoisting equipment to be loaded onto or unloaded from the transport carrier 41, which is very convenient.

[0138] By using the feeding method, the whole process is automatically operated, and the feeding efficiency is greatly improved.
