Description

Technical Field

[0001] The utility model belongs to the technical field of unpacking equipment, and in particular relates to an industrial powder and granular material unpacking machine. Background Art

[0002] Bag unpackers are primarily used in applications requiring the handling of bagged powdered or granular materials, such as chemical plants, pharmaceutical factories, food processing plants, electronics factories, and building materials factories. In these applications, powder bag unpackers can quickly and accurately unload powdered materials, improving production efficiency and reducing labor costs while protecting operator safety and environmental cleanliness.

[0003] During the unpacking operation, the material belt is driven by the conveying device to pass through the cutting station, discharge station and bag discharge station in sequence. At the cutting station, the cutting mechanism cuts the material bag open; at the discharge station, the material falls into the hopper; finally, at the bag discharge station, the empty bag is sent to the bag discharge bin and discharged directly from the bag discharge bin.

[0004] At present, a commonly used conveying device is to lift the material bag filled with material and send it to the cutting station, where the cutting mechanism at the cutting process cuts the material bag open; then it is lifted to the upper side of the hopper, that is, the unloading station, so that the material falls into the hopper, and then the empty bag is lifted to the bag discharge station, the empty bag is released, and finally it returns to the initial position to lift the next bag of material, and so on.

[0005] Only after the previous bag of material is unpacked and the conveying device is reset can the next bag of material be lifted and unpacked. That is, one complete stroke of the unpacking machine conveying device can only complete one unpacking operation. Therefore, the unpacking efficiency is low. Utility Model Content

[0111] Specifically, the support frame includes three support shafts 2091 and two support plates 2092. The three support shafts 2091 are distributed in a herringbone shape, and the two support plates 2092 are spaced apart to support the chain conveyor belt and prevent the chain conveyor belt from falling.

[0112] like Figures 6 to 9 As shown, in a specific embodiment of the industrial powder and granular material unpacking machine provided by an embodiment of the present utility model, the cutting mechanism includes a swing arm assembly, a cutting blade 3020, a blade drive assembly and a tension assembly, one end of the swing arm assembly is connected to the housing 1010, and the upper side of the swing arm assembly is fixedly connected to the rocker arm 3015; the cutting blade 3020 is connected to the other end of the swing arm assembly; the blade drive assembly is connected to the housing 1010, and the power output end is connected to the cutting blade 3020 to drive the cutting blade 3020 to rotate; one end of the tension assembly is connected to the free end of the rocker arm 3015, and the other end is connected to the housing 1010.

[0113] The swing arm assemblies of the two cutting mechanisms are suitable for rotating and opening in opposite directions under the push of the material bag, and the tension assembly is used to provide reverse tension for the swing arm assembly when the material bag pushes the swing arm assembly to rotate.

[0114] The two swing arm assemblies are arranged in an "V" shape on the upper side of the conveying mechanism of the unpacking machine; when the conveying mechanism transports the material bag through, the two swing arm assemblies are pushed open by the thrust of the conveying mechanism on the material bag. In this process, the front end and two sides of the material bag are cut open.

[0115] It should be noted that during operation, the material bag is transported by the chain conveyor assembly 2000. At the same time, a hook assembly is set to hook the material bag to provide sufficient thrust for the material bag. The two swing arm assemblies are pushed open by relying on the pushing force of the material bag and reset by the tension assembly. Therefore, after the two swing arm assemblies are opened, the spacing between the two cutting blades 3020 can change with the change of the width of the material, without the need to reset the parameters as the specifications of the material bag change, which is more convenient to use; at the same time, the tension assembly applies tension to the opened swing arm assembly. When the material is harder and the cutting blade 3020 cannot cut into the material, the cutting blade 3020 can rely on the tension of the tension assembly to press against the surface of the material bag, so that there is sufficient contact pressure between the cutting blade 3020 and the material bag to ensure the cutting effect.

[0116] like Figures 6 to 9 As shown, in a specific embodiment of the industrial powder and granular material unpacking machine provided by the embodiment of the present utility model, the swing arm assembly includes a shell 3090, an arm body 3012, a first shaft sleeve 3011, a second shaft sleeve 3013 and a knife shaft 3014, the shell 3090 is connected to the housing 1010; the arm body 3012 is arranged horizontally and has a cavity inside; the first shaft sleeve 3011 is inserted into the shell 3090 and rotates with the shell 3090. The first shaft sleeve 3011 The lower end is connected to one end of the arm body 3012, and the upper end is connected to the rocker arm 3015. The end of the rocker arm 3015 away from the first sleeve 3011 is the free end; the second sleeve 3013 is vertically arranged on the lower side of the arm body 3012, and the upper end is connected to the other end of the arm body 3012; the knife shaft 3014 is passed through the second sleeve 3013 and rotates with the second sleeve 3013; the cutting blade 3020 is connected to the lower end of the knife shaft 3014.

[0117] It should be noted that the arm body 3012, the first sleeve 3011, the second sleeve 3013 and the knife shaft 3014 form a "┌┘"-shaped structure, the cutting blade 3020 is arranged horizontally, the upper end is rotatably matched with the housing 1010, and the cutting blade 3020 is installed at the lower end.

[0118] Specifically, the blade drive assembly includes a transmission shaft 3031, a motor assembly 3032 and a transmission assembly. The transmission shaft 3031 is inserted into the first shaft sleeve 3011, and the lower end extends into the arm body 3012; the power output end of the motor assembly 3032 is connected to the transmission shaft 3031 to drive the transmission shaft 3031 to rotate; the transmission assembly is arranged in the arm body 3012; the transmission assembly includes a synchronous belt 3042 and two synchronous wheels 3041, and the two synchronous wheels 3041 are respectively connected to the transmission shaft 3031 and the blade shaft 3014, and the synchronous belt 3042 is sleeved on the two synchronous wheels 3041.

[0119] Specifically, the transmission assembly can also be a sprocket and chain 2031 or a pulley and belt, etc.

[0120] It should be noted that bearings are provided between the transmission shaft 3031 and the first shaft sleeve 3011 , between the first shaft sleeve 3011 and the shell 3090 , and between the knife shaft 3014 and the second first shaft sleeve 3011 to reduce friction.

[0121] like Figure 6 As shown, in a specific embodiment of the industrial powder and granular material unpacking machine provided by an embodiment of the present utility model, the pulling assembly includes a pull rod 3051 and a spring 3052, and the pull rod 3051 is rotatably matched with the housing 1010; one end of the spring 3052 is connected to the pull rod 3051, and the other end is connected to the end of the rocker arm 3015 away from the first sleeve 3011.

[0122] It should be noted that the pull rod 3051 is provided with a rotating shaft 4001, which is rotatably matched with the housing 1010 so that the spring 3052 only bears axial force without bearing torque.

[0123] like Figure 6 and Figure 7 As shown, in a specific embodiment of the industrial powder and granular unpacking machine provided by an embodiment of the present utility model, the cutting mechanism also includes a power-assisting cylinder 3060, a stopper 3070 and a sensor 3080, one end of the power-assisting cylinder 3060 is hinged to the free end of the rocker arm 3015, and the other end is hinged to the housing 1010; the power-assisting cylinder 3060 is used to provide an opening thrust for the rocker arm assembly, and the thrust is less than the resistance of the rocker arm assembly when it is opened; the stopper 3070 is connected to the housing 1010, and is suitable for abutting against the side of the rocker arm 3015 in the initial position toward the tension assembly; the sensor 3080 is fixedly arranged to detect the position of the rocker arm 3015.

[0124] It should be noted that if the thrust provided by the conveying assembly to the material bag is small and insufficient to overcome the resistance when the swing arm assembly rotates, the swing arm assembly will not be pushed and will remain on the conveying assembly, resulting in the inability to perform cutting operations; therefore, a power-assisting cylinder 3060 is provided, and while the material bag pushes the swing arm assembly, the power-assisting cylinder 3060 pushes the swing arm assembly to help the material bag push the swing arm assembly open, thereby preventing the material bag from being retained on the conveying assembly; and since the thrust of the separate power-assisting cylinder 3060 on the swing arm assembly is less than the resistance when the swing arm assembly is opened, it can still be ensured that the swing arm assembly is passively pushed open by the material bag, can still automatically adapt to the specifications of the material bag, and maintains a certain contact pressure between the cutting blade 3020 and the material bag to ensure the cutting effect.

[0125] In the initial state, rocker arm 3015 is close to sensor 3080. When the material bag begins to push against the rocker arm assembly, rocker arm 3015 rotates slightly, away from sensor 3080. Sensor 3080 detects this and sends a signal, causing booster cylinder 3060 to begin synchronous operation, providing assistance to the material bag. Specifically, sensor 3080 is a proximity switch, but it can also be a photoelectric sensor 3080, a micro switch, or other sensor that can detect the rotation of rocker arm 3015.

[0126] like Figure 1 and Figure 2 As shown, in a specific embodiment of the industrial powder and granular material unpacking machine provided by the embodiment of the present utility model, it also includes a bag blocking assembly, which is arranged on the upper side of one end of the chain conveyor assembly 2000 away from the feed port and is connected to the housing 1010. The bag blocking assembly is suitable for abutting the end of the upper half of the material bag that is cut horizontally. The bag blocking assembly includes a rotating shaft 4001, a bag blocking frame 4002, a connecting rod 4003, a limit plate 4004 and a baffle 4005. The rotating shaft 4001 001 at both ends rotate with the casing 1010; the bag blocking frame 4002 is arranged on the lower side of the rotating shaft 4001, and the bag blocking frame 4002 is suitable for abutting the end of the upper half of the material bag that is cut horizontally; one end of the connecting rod 4003 is connected to the rotating shaft 4001, and the other end is connected to the bag blocking frame 4002; the limiting plate 4004 is connected to one end of the rotating shaft 4001; the baffle 4005 is arranged on the side of the rotating shaft 4001 facing the feed port, and is suitable for abutting with the limiting plate 4004.

[0127] Specifically, the bag blocking frame 4002 is arranged on the upper side of the end of the conveyor belt. When the material bag moves to this position, the bag blocking frame 4002 abuts against the end of the upper half of the transversely cut material bag, and the lower half is hooked by the hook 2052. The movement continues, and the bag blocking frame 4002 cooperates with the hook 2052 to open the material bag, and the material falls into the bottom hopper 1011; the empty material bag enters between the bag rack 2080 and the chain conveyor belt, and is transported to the bag discharge bin 1012.

[0128] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent replacements and improvements made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
