[0037] The specific implementation of the present utility model is described below in conjunction with the accompanying drawings.

[0038] like Figures 1 to 3As shown, the interior of the chassis 100 of the ton bag opening system of the utility model is separated into mutually independent grabbing bins 101, bag opening bins 102, recycling bins 103 and transmission boxes 104 by partitions. The grabbing bins 101, bag opening bins 102 and recycling bins 103 are arranged in parallel in sequence, and the transmission box 104 is located above the grabbing bins 101, bag opening bins 102 and recycling bins 103; fast doors 107 are respectively arranged between the grabbing bins 101, the grabbing bins 101 and the bag opening bins 102, and between the bag opening bins 102 and the recycling bins 103. The grabbing bins 101, the grabbing bins 101, the bag opening bins 102 and the external environment are isolated from each other by fast doors 107 and a sealed cover, and the grabbing bins 101, the bag opening bins 102, the recycling bins 103 and the transmission box 104 are separated into closed independent bins, thereby avoiding secondary contamination between the bins. The chassis 100 is provided with a dust collector 30, and the grabbing bin 101, the unpacking bin 102, and the recycling bin 103 are respectively provided with independent dust removal mechanisms 106, which are connected to the dust collector 30 through pipelines. Each independent dust removal mechanism 106 can remove dust impurities or dust in each bin to ensure the cleanliness of the material and meet the requirements of health safety and environmental safety. The grabbing bin 101, the unpacking bin 102, and the recycling bin 103 can be provided with an online dust concentration monitoring device to monitor the dust concentration in real time, and adjust the dust removal power according to the real-time dust concentration to prevent dust leakage when the rapid door 107 is opened to pollute other bins or the external environment.

[0039] like Figure 3 As shown, the grabbing bin 101 is provided with an automatic deviation correcting device 1, a bag hanging and lifting device 2, an air shower device 3, a bottom cleaning device 4 and a tearing and sticking component 5.

[0040] like Figure 3 As shown, the automatic deviation correcting device 1 is arranged below the bag hanging lifting device 2. Figure 4As shown, the automatic deflection correction device 1 includes a base frame 11, a slewing bearing 12 and a deflection correction turntable 13 are arranged on the top of the base frame 11, and the deflection correction turntable 13 is connected to the base frame 11 through the slewing bearing 12; the deflection correction turntable 13 is connected to the driving mechanism, and the driving mechanism can drive the deflection correction turntable 13 to rotate within the range of ±90° (i.e., 90° forward and reverse rotation); a position sensor is arranged on the outer side of the deflection correction turntable 13, and a plurality of rollers 14 are arranged on the deflection correction turntable 13 to facilitate the pallet to move with the ton bag 200. After the ton bag 200 is fed in through the pallet, it is placed on the deflection correction turntable 13 together with the pallet. The deflection correction turntable 13 is driven by the driving mechanism to rotate at a suitable angle according to the position of the hanging ear of the ton bag 200, so that the hanging ear of the ton bag 200 is directly opposite to the clamping device 24 of the bag hanging lifting device 2, so that the clamping device 24 of the bag hanging lifting device 2 can hang the bag smoothly and accurately, thereby improving the bag hanging efficiency. The automatic deviation correction device 1 determines whether the rotation angle is appropriate and whether the hanging ears of the ton bag 200 are aligned with the clamping device 24 through an image sensor, and the image sensor is arranged in the grabbing bin 101. The deviation correction turntable 13 of the automatic deviation correction device 1 can rotate within the range of ±90° to achieve angle adjustment, and can adjust the ton bag 200 in any irregular placement position to an angle that can achieve bag hanging, which reduces the requirements for placing the ton bag 200 on the pallet position, and also ensures the accuracy and success rate of the ton bag 200 hanging bag.

[0041] like Figure 5 As shown, the bag hanging lifting device 2 is provided with a bracket 21, an electric cylinder 22, a weighing device 23 and a clamping device 24. The bracket 21 is connected to the electric cylinder 22, and the electric cylinder 22 can drive the bracket 21 to rise and fall. The clamping devices 24 are respectively provided on the opposite sides of the bottom surface of the bracket 21 and the corresponding ears of the ton bag 200. The weighing device 23 is provided on the bracket 21, and the weighing device 23 has a built-in weighing sensor. The weighing sensor is used to judge the real-time situation of the material in the ton bag 200 after the ton bag 200 is broken, and to judge whether the material in the ton bag 200 has fallen out, so as to avoid the material remaining in the ton bag 200.

[0042] like Figure 3 As shown, the air shower device 3 is arranged on two opposite sides of the grabbing bin 101, an air outlet 31 is arranged at the upper part of the air shower device 3, and an air inlet 32 ​​is arranged at the lower part. The wind enters the grabbing bin 101 from the lower air inlet 32, flows upward and flows out from the upper air outlet 31, forming a circulating air path to blow away impurities on the surface of the ton bag 200.

[0043] like Figure 3 As shown, the bottom cleaning device 4 and the tear-off and sticking member 5 are arranged between the automatic deviation correcting device 1 and the bag hanging lifting device 2. After the ton bag 200 is lifted, the bottom cleaning device 4 and the tear-off and sticking member 5 correspond to the bottom of the ton bag 200. Figure 6As shown, the bottom cleaning device 4 includes a brush 41 and a linear module 42. The brush 41 is connected to the linear module 42. The linear module 42 can drive the brush 41 to move left and right along a straight line to clean the bottom of the ton bag 200 and remove impurities at the bottom of the ton bag 200. Figure 7 , Figure 8 As shown, the tear-off piece 5 is fixed on the chassis 100, corresponding to the Velcro 2001 at the bottom of the ton bag 200. When the ton bag 200 is transferred from the grabbing bin 101 to the unpacking bin 102, the tear-off piece 5 hooks the Velcro 2001 at the bottom of the ton bag 200. As the ton bag 200 moves, the Velcro 2001 is hooked and torn off by the tear-off piece 5, thereby exposing the broken bag part of the ton bag 200.

[0044] like Figure 3 As shown, a bag breaking assembly 6 , a plurality of beating devices 7 , and a powder delivery device 8 are arranged in the bag opening bin 102 .

[0045] The bag breaking assembly 6 includes a bag opening knife 61, a knife holder 62 and a silo 63. The bag opening knife 61 is fixed on the knife holder 62. The silo 63 is a cone bucket for easy material dropping. The bag opening knife 61 is located at the center of the top of the silo 63. The powder delivery device 8 is connected to the bottom of the silo 63. The chassis 100 is provided with an inspection port 105 corresponding to the bag breaking assembly 6, which is convenient for the inspection and replacement of the bag opening knife 61.

[0046] The flapping device 7 is arranged above the bag breaking assembly 6. Figure 3 , Fig. 9As shown, the flapping device 7 includes a flapping frame 71, a rope 72, a cylinder 73, and a plurality of pulleys 74. One end of the flapping frame 71 is rotatably hinged on a seat 75, and the seat 75 is fixed on the chassis 100; the middle of the flapping frame 71 is connected to one end of the rope 72, and the rope 72 passes through a plurality of fixed pulleys 74 upwards, and the other end is connected to the piston rod of the cylinder 73; the plurality of pulleys 74 guide and limit the direction of the rope 72, ensuring that the rope 72 moves on a specified path, and preventing the rope 72 from interfering with the movement of the ton bag 200 and the bag hanging lifting device 2. A guide wheel 76 is provided on the flapping frame 71, and the rope 72 passes through the guide wheel 76 and then is connected to the flapping frame 71, ensuring the movement path of the rope 72 and smoothly driving the flapping frame 71 to rotate. The cylinder 73 is arranged in the transmission box 104 at the top of the unpacking bin 102, and the rope 72 and the pulley 74 are located above the rupture of the ton bag 200. On the one hand, the cylinder 73 is arranged in the transmission box 104 outside the unpacking bin 102 as a driving cylinder, and is not affected by the materials in the unpacking bin 102, which not only saves the protective structure, but also avoids the failure or wear caused by the entry of materials; on the other hand, the cylinder 73 is arranged in the transmission box 104, and the rope 72 and the pulley 74 are arranged in the unpacking bin 102, but they are both located at the ton bag 200. Above the breach, only part of the beating frame 71 is located below the ton bag 200. When the material falls from the breach of the ton bag 200 under the action of gravity, it will not come into contact with the components above the breach, thereby avoiding contamination of the material due to contact and ensuring the quality of the material. When the ton bag 200 enters the bag opening bin 102, the beating frame 71 holds the bottom of the ton bag 200 to prevent the bottom bag from hitting the tip of the knife and scratching the ton bag 200. In addition, multiple groups of beating frames 71 form a cone when breaking the bag, which is conducive to the concentration of powder materials at the four corners of the ton bag 200 to the center of the bag. In the initial state of the beating device 7, that is, during the transfer of the ton bag 200 from the grabbing bin 101 to the unpacking bin 102, the beating frame 71 is in a horizontal state, which can play a certain protective role for the ton bag 200, so that the bottom of the ton bag 200 can be prevented from hitting the tip of the unpacking knife 61 in advance before and during the transfer, causing the material to fall in advance, which will not only affect the unpacking and dropping of the ton bag 200, but also easily cause pollution to the material. After the ton bag 200 is transferred to the right place and the bag is broken and the material is dropped, the cylinder 73 drives the beating frame 71 to swing and beat the ton bag 200 through the rope 72, assisting the dropping of the material, ensuring that all the materials in the ton bag 200 are discharged, and avoiding residual materials in the ton bag 200.

[0047] like Figure 3 As shown, a waste bag compression and sorting device 9 is provided in the recovery bin 103 .

[0048] like Fig.10As shown, a compression and folding device 92 is arranged in a frame 91 of the waste bag compression and sorting device 9, a movable recovery frame 93 is arranged on one side of the frame 91, the compression and folding device 92 and the recovery frame 93 are arranged in parallel front and back, and a limit lever 94 is arranged on the compression and folding device 92.

[0049] like Fig.11 As shown, the compression and folding device 92 includes a vertically arranged pressing frame 921 and a pressing frame 922. Fig.10 As shown, the pressing frame 921 is a square frame with unobstructed front and rear vertical surfaces, which is fixedly connected to the frame 91. The pressing frame 922 is a vertical plane frame, which is arranged in the frame 91 so as to be movable toward the pressing frame 921. The left and right ends of the pressing frame 922 are slidably arranged on the guide rods 911 of the frame 91, and the pressing frame 922 is connected to a driving mechanism, which can drive the pressing frame 922 to move along the guide rods 911 toward the pressing frame 921. A plurality of folding plates 923 are arranged between the pressing frame 921 and the pressing frame 922, and the folding plates 923, the folding plates 923, the pressing frame 921 and the pressing frame 922 are connected respectively by movable hinges 924, and the folding plates 923 can rotate around the movable hinges 924, and the plurality of folding plates 923 can be folded inwardly toward the inner side of the frame 91 or opened outwardly.

[0050] like Fig.12 As shown, a vertical pressing plate 931 is arranged in the recovery frame 93 and faces the compression and folding device 92, and the pressing plate 931 can move forward and backward facing the compression and folding device 92. Casters 932 are arranged at the bottom of the recovery frame 93, and the recovery frame 93 can be moved out as a whole through the casters 932.

[0051] like Fig.10 As shown, a part of the recovery frame 93 extends into the pressing frame 921 of the compression and folding device 92, and the limit lever 94 is arranged on the pressing frame 921. After the waste bag is pressed into the pressing frame 921 by the pressing frame 922, the limit lever 94 blocks the outside of the waste bag to prevent the waste bag from rebounding. After the waste bag is placed in the frame 91, the driving mechanism drives the pressing frame 922 to move toward the pressing frame 921, and the folding plate 923 folds inward to compress and fold the waste bag until the waste bag is pressed onto the pressing plate 931 of the recycling frame 93, and the limiting lever 94 presses the waste bag onto the pressing plate 931 (and at this time the pressing plate 931 moves backward by a distance of a compressed bag), and then the driving mechanism drives the pressing frame 922 and the folding plate 923 to open, and continue the recycling of the next waste bag; with the squeezing of subsequent waste bags, the front waste bag is gradually pressed into the recycling frame 93, until the recycling frame 93 is filled, the recycling frame 93 together with the collected waste bags are moved out as a whole, and the empty recycling frame 93 is replaced to continue the collection of waste bags.

[0052] The waste bag compression and sorting device 9 folds and compresses the waste bags through the compression and folding device 92 and then presses them into the recycling frame 93, so that storage is achieved in one step, which saves the manual folding procedure and saves time and labor.

[0053] like Fig.13 As shown, a sealed bagging device 95 can also be provided on the waste bag compression and sorting device 9 to seal and recycle the compressed waste bags. The sealed bagging device 95 includes an elastic support component 951 and a bag 952. The elastic support component 951 is fixed on the frame 91. The open end of the bag 952 is pressed by the elastic support component 951. The bag body of the bag 952 is inserted into the recycling frame 93. When the waste bag is recycled, the waste bag is pressed into the bag 952 to achieve sealed dust-free recycling of the waste bag and avoid the dust in the waste bag from affecting the environment.

[0054] Fig.13 a)-e) show the waste bag collection process of the waste bag compression and sorting device 9 with a sealing bagging device 95:

[0055] a) First, the cover bag 952 is fixed on the frame 91 through the elastic support assembly 951, the bag body of the cover bag 952 is inserted into the recycling frame 93, and the waste bag is continuously pressed into the cover bag 952 of the recycling frame 93 by the compression and folding device 92;

[0056] b) After the waste bags in a bag 952 are filled, the recycling frame 93 is moved out together with the bag 952 filled with waste bags, and then two tie ties 953 are tied to the open end of the bag 952. The two tie ties 953 are spaced apart. One tie 953 is used to tie the bag opening of the previous bag 952 (i.e., the bag 952 filled with waste bags) for sealing, and the other tie 953 is used to tie the bag bottom of the next bag 952 (i.e., the next bag 952 ready to collect waste bags) for sealing;

[0057] c) After the bag 952 is tied, it is cut from the area between the two tie ties 953, that is, the front and rear bags 952 are disconnected;

[0058] d) After the bag 952 is cut, the bag 952 filled with waste bags and sealed is removed from the recycling frame 93;

[0059] e) After the filled cover bag 952 is moved out, the recovery frame 93 is moved back in, and the next cover bag 952 is inserted into the recovery frame 93 to collect the waste bags of the next cover bag 952.

[0060] By repeatedly following the above steps a)-e), continuous, sealed and dust-free recycling of waste bags can be achieved.

[0061] like Figure 3As shown, a guide rail 10 and a belt transmission mechanism 20 are provided in the transmission box 104, and the bag hanging lifting device 2 is connected to the belt transmission mechanism 20. The bag hanging lifting device 2 moves back and forth in the grabbing bin 101, the bag opening bin 102 and the recovery bin 103 through the belt transmission mechanism 20 to transfer the ton bag 200. The belt transmission mechanism 20 includes a motor 201, a synchronous belt 202 and a slider assembly 203. The motor 201 is connected to one end of the synchronous belt 202, and the synchronous belt 202 and the slider assembly 203 are connected to the bag hanging lifting device 2. The slider assembly 203 is slidably arranged on the guide rail 10.

The bag hanging lifting device 2 is transported by the belt transmission mechanism 20, has a simple structure, stable operation, no metal friction is generated during the movement, and has a more efficient, safe and reliable structure.

[0062] When the utility model is actually used, first, the first fast door 107 is opened, and the latter two fast doors 107 are closed; the ton bag 200 is transferred to the automatic deviation-correcting device 1 together with the pallet, and with the assistance of the image sensor, the deviation-correcting turntable 13 of the automatic deviation-correcting device 1 drives the ton bag 200 to rotate for deviation correction until the hanging ear of the ton bag 200 is aligned with the positive clamping device 24 of the hanging bag lifting device 2; the hanging bag lifting device 2 moves downward until the hook of the positive clamping device 24 reaches directly below the hanging ear of the ton bag 200, and the automatic deviation-correcting device 1 can continue to rotate for fine adjustment, so that the hook of the clamping device 24 is more accurately hung on After the bag is hung, the bag lifting device 2 moves up to lift the ton bag 200, the automatic deviation correction device 1 rotates back to the origin, the pallet is taken out, and then the first fast door 107 is closed, and the air shower device 3 is started to purge the ton bag 200. At the same time, the linear module 42 of the bottom cleaning device 4 drives the brush 41 to clean the bottom of the ton bag 200; after the cleaning is completed, the air shower device 3 and the bottom cleaning device 4 are closed, and the second fast door 107 is opened. The bag lifting device 2 carries the ton bag 200 to the bag opening warehouse 102. During the transfer process, the tearing and sticking piece 5 takes advantage of the situation to lift the ton bag 200. 0 is hooked and torn off, exposing the broken bag part; the ton bag 200 is transferred to the top of the bag breaking component 6 in the bag opening bin 102.
