[0044] Reference Figure 1-Figure 3 The embodiment of the present application provides a ton bag 13 bag opening machine, including a frame 1, a silo 2 is arranged on the frame 1, a loading port 21 is opened on the top of the silo 2, and further includes:

[0045] A bag breaking knife 3 is arranged in the bin body 2;

[0046] A dust removal mechanism is disposed in the bin body 2 and located above the bag breaking knife 3; and

[0047] A cover plate is movably disposed on the frame 1 , and the cover plate has a first state of covering the loading port 21 and a second state of opening the loading port 21 .

[0048] When the cover is in the second state, the loading port 21 is opened, and the ton bag 13 can be transferred to the lifting position directly above the warehouse body 2 by a forklift or an automatic guided vehicle. After that, the ton bag 13 can be moved down and placed inside the warehouse body 2 through the loading port 21 for subsequent unpacking operations. During the process of the ton bag 13 moving down in the warehouse body 2, until the bag-breaking knife 3 acts on the bottom of the ton bag 13, the ton bag 13 is punctured to achieve automatic bag breaking; the material in the ton bag 13 flows out of the warehouse body 2 through the rupture on the ton bag 13. During the process of material outflow, high-level dust can be removed by the dust removal mechanism. During the unpacking operation, the cover can be controlled to be in the first state to cover the loading port 21 to prevent the material from flying around through the loading port 21. At the same time, when the ton bag 13 unpacking machine is in the standby or shutdown state, the cover can also be controlled to be in the first state to cover the loading port 21 to prevent debris from falling into the warehouse body 2.

[0049] In summary, the ton bag 13 opening machine provided in this embodiment reduces the involvement of technicians in the process of opening the ton bag 13, reduces manual operation procedures, and greatly reduces the labor intensity of technicians.

[0050] Among them, the ton bag 13 in the embodiment of the present application can also be called a container bag or a woven bag, which is a large plastic bag used to store and transport bulk materials. The ton bag 13 is usually made of polypropylene fiber, and has the characteristics of high strength, wear resistance, waterproof and moisture-proof, and easy loading and unloading. The ton bag 13 is usually designed as a cube or a rectangular parallelepiped. When in use, one or more openings can be set on the surface of the ton bag 13 to facilitate pouring or unloading of bulk materials, such as chemicals, grains, minerals, building materials, etc. Secondly, the ton bag 13 can also be suspended using a lifting ring or other lifting device for easy transportation.

[0051] In some embodiments, the cover plate is movably arranged on the frame 1, and the cover plate has a first state of covering the loading port 21 and a second state of opening the loading port 21. The movement of the cover plate can be achieved by any achievable driving component, such as a cylinder or a motor, etc. to move or rotate to achieve the opening or covering of the loading port 21. Of course, the cover plate can also include a first cover plate and a second cover plate, and the opening and covering of the loading port 21 can be achieved by the movement of the first cover plate and the second cover plate approaching or moving away from each other. The movement of the first cover plate and the second cover plate can be driven separately by two driving components, or a driving component can be connected with a transmission component to achieve synchronous drive, such as a motor and a gear rack matching method, or a motor and a bidirectional screw rod matching method. The specific connection structure of the above-mentioned driving method can refer to the prior art, and this embodiment does not limit this.

[0052] Combination Figure 4 In some embodiments, the bag breaking knife 3 has a notch 31, that is, the bag breaking knife 3 is arranged in a C-shaped structure as a whole. Through the setting of the notch 31, when the bag breaking knife 3 acts on the ton bag 13, it can ensure that the ton bag 13 can be opened, and the bag opening after opening will not fall from the whole bag, effectively preventing the debris of the ton bag 13 from falling into the warehouse body 2.

[0053] Among them, the bag breaking knife 3 is made of hard material to ensure effective bag breaking effect. Optionally, the blade of the bag breaking knife 3 is made of high hardness and wear-resistant metal material 440C. In addition, in order to ensure the bag breaking effect, the blade of the bag breaking knife 3 can be supported at multiple points without extrusion deformation, ensuring smooth bag breaking without burrs.

[0054] Specifically, the bag-breaking knife 3 can be fixedly arranged in the bin body 2, or can be detachably arranged in the bin body 2. That is, the bag-breaking knife 3 can be welded inside the bin body 2, or can be detachably connected to the bin body 2 by bolts or other connection methods. As an example, a pin is provided between the bag-breaking knife 3 and the bin body 2, and the pin passes through the bin body 2 and is connected by bolts on the outside of the bin body 2. This connection method not only facilitates the disassembly and replacement of the bag-breaking knife 3, but also prevents the situation where the bolts fall off in the bin body 2.

[0055] In some embodiments, a screen 9 is provided in the bin body 2, and the screen 9 is located below the bag breaking knife 3. The setting of the screen 9 can collect the fallen bag skin to prevent the bag skin from being mixed with the material and entering the next process together. At the same time, the setting of the screen 9 can also have a certain effect of breaking up the material and reducing the agglomeration of the material. Among them, the screen 9 can be detachably arranged in the bin body 2, and the screen 9 can adopt any detachable connection method in the prior art, which will not be described in detail in this embodiment. In this way, technicians can replace screens 9 with different apertures according to the properties of different materials.

[0056] Reference Figure 1-Figure 2 Of course, the silo 2 is also provided with a weighing module 10 and a second vibrator 11, and the silo 2 is weighed by the weighing module 10, and the silo 2 is vibrated by the second vibrator 11. Among them, the weighing module 10 can intuitively understand the situation in the silo 2 through the weight data; that is, when the ton bag 13 is not placed in the silo 2, the weighing module 10 detects the weight of the silo 2. When the ton bag 13 is placed in the silo 2, and as the ton bag 13 gradually interacts with the bag breaking knife 3, the weight detected by the weighing module 10 gradually increases, and after the ton bag 13 is completely located on the bag breaking knife 3, the weight value detected by the weighing module 10 remains stable. At this time, the technician can understand that the bag breaking operation is being carried out inside the silo 2. Of course, according to the weight detected by the weighing component, the technician can also assist in understanding the bag breaking situation of the ton bag 13 and the material unloading speed and unloading amount.

[0057] Specifically, after the ton bag 13 gradually moves downward from the feeding port 21 and the bottom of the ton bag 13 contacts the bag breaking knife 3, the ton bag 13 is controlled to fall a specified distance to complete the bag breaking. After the bag breaking is completed, the ton bag 13 is controlled to rise, and the material begins to fall by itself due to its own gravity. The gravity of the ton bag 13 is used to perform automatic bag breaking to realize automatic bag opening.

[0058] It can be known that the material is transported to the next process through the feed pipe at the bottom of the silo 2. Specifically, a rotary valve 12 is arranged between the bottom of the silo 2 and the feed pipe. When the material falls from the silo 2 into the rotary valve 12 under the action of negative pressure, the powdered material accumulates in the silo 2 and bridging is likely to occur. When the weighing module 10 detects that bridging exists in the silo 2, the second vibrator 11 is controlled to work, and the second vibrator 11 breaks the arch to ensure smooth material falling.

[0059] In order to ensure the weighing and vibration effects, a plurality of weighing modules 10 may be provided, and the plurality of weighing modules 10 may be evenly spaced around the hopper body 2. A plurality of second vibrators 11 may also be provided, and the plurality of second vibrators 11 may be evenly spaced around the hopper body 2.

[0060] Reference Figure 1-Figure 6 In some embodiments, the dust removal mechanism includes a first dust removal component 4, which includes a circular tube 41, a plurality of receiving ports 42 are spaced apart on the inner side of the circular tube 41, and a discharge port 43 is provided on the outer side of the circular tube 41, and the discharge port 43 is used to connect the conveying pipe; the circular tube 41 is located above the broken knife bag, and the material located on the upper side of the interior of the silo 2 is collected through the receiving port 42, and the collected material is transported to the conveying pipe through the discharge port 43 of the circular tube 41, and transported to the next process, thereby reducing material waste.

[0061] In addition, in order to ensure the directionality of material transportation, the conveying pipe is also connected to a first negative pressure machine. The first negative pressure member can be a first fan, etc., so that the material moves toward the conveying pipe under the action of negative pressure.

[0062] Of course, the lower port of the bin body 2 is connected to the rotary valve 12, and the unloading speed and accuracy are controlled by controlling the rotation rate; the acceleration chamber below the rotary valve 12 is loaded with negative pressure by the loading fan to accelerate the material transportation, and it can also be connected to the conveying pipe to reduce material waste.

[0063] The dust removal mechanism also includes a second dust removal component 5, which includes an annular tube 51. The annular tube 51 is located above the circular tube 41, and a plurality of dust suction ports 52 are spaced apart on the inner side thereof. A dust outlet 53 is provided on the outer side of the circular tube 41, and the dust outlet 53 is used to connect to a dust removal pipe. The dust in the bin body 2 is sucked into the annular tube 51 through the dust outlet 53, and the dust is collected centrally through the dust removal pipe.

[0064] Of course, the dust removal pipe may also be connected to a second negative pressure component, which may be a second fan, etc. The negative pressure absorption effect is achieved through the operation of the second fan.

[0065] The dust suction port 52 may be provided with a trapezoidal oblique cross-section structure, so that the accumulated materials automatically fall back, thereby preventing dust accumulation from affecting the dust removal effect.

[0066] Optionally, the dust removal mechanism also includes a lifting assembly 6, the movable end of the lifting assembly 6 is connected to the annular tube 51, and the height between the annular tube 51 and the circular ring tube 41 is adjusted; by adjusting the height between the annular tube 51 and the circular ring tube 41, the best dust removal effect can be achieved according to different materials.

[0067] Among them, the lifting assembly 6 can be any component that can achieve lifting in the prior art, such as a cylinder, a hydraulic cylinder or an electric push rod. Exemplarily, the lifting assembly 6 includes a screw, which is arranged vertically, one end of the screw is connected to the warehouse body 2, the annular tube 41 is arranged on the warehouse body 2, the annular tube 51 cooperates with the screw, and the screw penetrates the annular tube 51 along its own axial direction; that is, the height of the annular tube 51 can be adjusted by rotating the screw, and then the height between the annular tube 51 and the annular tube 41 can be adjusted. It can be known that the screw and the warehouse body 2 can be fixedly connected, at this time, the screw and the annular tube 51 are penetrated, and nuts connected to the screw thread are arranged on the upper and lower sides of the annular tube 51 or the lower side of the annular tube 51, and the annular tube 51 is supported by the nut. In addition, the screw can also be fixedly connected to the annular tube 51, and the screw and the warehouse body 2 are screwed together.

[0068] Of course, in order to ensure the stability of the annular tube 51, two or more lifting assemblies 6 can be provided.

[0069] Reference Figure 1-Figure 6 In some embodiments, a material-swatting mechanism 7 is provided on the frame 1, and the material-swatting end of the material-swatting mechanism 7 is movably arranged at the loading port 21 and acts on the ton bag 13; by setting the material-swatting mechanism 7 after the ton bag 13 is opened, during the process of automatic material dropping, the material dropping speed in the ton bag 13 can be accelerated, and when the material in the ton bag 13 is less, the material in the ton bag 13 can also be beaten out, thereby ensuring the reliability of the material dropping of the ton bag 13, reducing the amount of material adhering to the ton bag 13, and reducing loss.

[0070] The material shooting mechanism 7 comprises:

[0071] A swing arm 71 is hingedly disposed on the frame 1;

[0072] A driving member 72, wherein a movable end of the driving member 72 is connected to one end of the swing arm 71, and the other end of the swing arm 71 is a material-striking end and is located at the feeding port 21;

[0073] The material-snapping mechanism 7 is symmetrically arranged in two groups, and the material-snapping ends of the swing arms 71 of the two groups of the material-snapping mechanism 7 move synchronously toward the direction of approaching or moving away from each other.

[0074] The driving member 72 may be a structure such as a cylinder, an electric push rod, or a motor and a connecting rod assembly, so as to ensure that the swing arm 71 can swing back and forth to act on the ton bag 13. As an example, the driving member 72 in this embodiment adopts a driving cylinder, one end of which is hinged to the frame 1, and the other end of which is hinged to the end of the swing arm 71; during the extension and retraction of the driving cylinder piston rod, the swing arm 71 swings back and forth with the part hinged to the frame 1 as the center, thereby ensuring that the material-slapping end of the swing arm 71 can swing back and forth, and ensuring the material-slapping effect.

[0075] The first vibrator 8 is provided on the material-beating end, and the first vibrator 8 can increase the vibration effect during the material-beating process, and further improve the cleaning effect of the residual materials in the ton bag 13. The first vibrator 8 can be a high-frequency vibrator, and when the ton bag 13 gravity-drops to the final bag-cleaning stage, high-frequency vibration is used to clean the residue in the bag.

[0076] In summary, when the ton bag 13 opening machine provided by the present application is used, the ton bag 13 is first moved to the top of the loading port 21, and the cover plate moves to open the loading port 21, and then the ton bag 13 is controlled to fall into the bin body 2 for bag cutting. After the bottom of the ton bag 13 contacts the bag breaking knife 3, it falls to the specified stroke to complete the bag breaking. After the bag breaking is completed, the ton bag 13 is controlled to rise, and the material begins to fall by gravity; the automatic bag opening uses the gravity of the ton bag 13 to perform automatic bag breaking, and the weighing module 10 assists in checking the bag breaking situation. When the ton bag 13 is opened, the dust removal mechanism is automatically opened, and the receiving port 42 of the circular tube 41 absorbs the material into the conveying pipe to reduce material waste; the upper layer adopts a trapezoidal oblique cross-section dust suction port 52, which is connected to the dust removal pipe to remove high-level dust. During the material dropping process, when the weighing module 10 detects that there is less material left in the bag according to the material dropping rate at the opening of the ton bag 13, the material slapping mechanism 7 starts to operate, and the ton bag 13 is slapped by the swing of the swing arm 71, and the material slapping mechanisms 7 on both sides cooperate with each other to cover the entire material dropping process of the ton bag 13, and the first vibrator 8 is combined with high-frequency vibration to shake the material in the bag into the silo 2, and the material dropping process is completed after the bag is cleared. After the ton bag 13 is completed, the crane will lift the empty bag to the bag picking area for manual bag collection, and the powder material will be sent under negative pressure. In the process of falling from the silo 2 into the rotary valve 12, the powder material will accumulate in the silo 2 and bridges will easily occur. When the weighing module 10 detects that there is a bridge in the silo 2, the second vibrator 11 is turned on to break the arch to ensure smooth powder dropping. The weighing module 10 detects the progress of feeding. When the negative pressure of the material in the silo 2 is sent, it is determined that the feeding is completed, and the program performs the return step, and the feeding is completed.
