Description

Technical Field

[0001] This utility model relates to the field of industrial production unpacking technology, and in particular to a fully automatic multi-layer bag unpacking machine. Background Technology

[0002] In industrial production, especially in industries such as chemicals, food, and pharmaceuticals, multi-layered packaging bags are widely used to package raw materials. These bags are typically made of multiple layers of different materials, possessing high strength and sealing properties, effectively protecting the internal materials from external environmental influences. However, before these raw materials can be incorporated into the production process, the packaging bags must be opened and the internal materials separated.

[0003] Traditional unpacking methods rely mainly on manual operation, which is not only inefficient and labor-intensive, but also poses potential safety hazards. Multi-layered packaging bags are made of different composite materials, and the layers are tightly bonded together, making it difficult to disassemble and separate them at once. During the unpacking process, it is necessary to ensure that the internal materials can be poured out smoothly and evenly to avoid blockages and accumulation.

The outer wall of the large driving gear 321 is meshed with a large driven gear 322. The output end of the large driven gear 322 is connected to a limit gear 323. The output end of the limit gear 323 is connected to a crushing auger 324. The outer wall of the large driving gear 321 away from the large driven gear 322 is connected to a rotating shaft 314 through a gear.

[0027] The output end of the first synchronous pulley 304 is connected to a rotating rod 309 through the guide plate 1. The output ends of the drive gears 308 are all connected to rotating rods 309. A positioning block 310 is connected to the outer wall of the rotating rod 309, and multiple guide plates 311 are connected to the outer wall of each positioning block 310. A limiting cylinder 312 is connected to the end of the rotating rod 309 away from the first synchronous pulley 304. The motor 302 is connected to the first synchronous pulley 304 via a first output shaft 303. The first synchronous pulley 304 is connected to two first synchronous belts 306 via a limiting seat 305.

[0028] In this system, motor 302 starts, serving as the power source for the entire system. The output of motor 302 transmits power through a first output shaft 303, which is connected to a first synchronous pulley 304, causing the pulley to rotate. The first synchronous pulley 304, through a first synchronous belt 306 on its outer wall, drives two second synchronous pulleys 307 to rotate. The outputs of the two second synchronous pulleys 307 are connected to a drive gear 308 via a transmission shaft, thus the drive gear 308 also begins to rotate. The drive gear 308 meshes with a first driven gear 313, transmitting power to the driven gear 313. 08 transmits power through the connected rotating rod 309. The rotating rod 309 drives multiple guide plates 311 to rotate through the positioning block 310 connected to the outer wall. The packaging bag is fed from above the guide plate 1. The multiple guide plates 311 guide the falling material to avoid blockage and achieve uniform feeding. The second synchronous wheel 307 at the end away from the active gear 308 transmits power to the rotating shaft 314 through the transmission shaft. The rotating shaft 314 drives the unpacking blades 315 on the outer wall to rotate. When the packaging bag is guided to the action area of ​​the unpacking blades 315, the rotating unpacking blades 315 will cut or tear the packaging bag, creating conditions for the subsequent material to fall.

[0029] The rotational kinetic energy of the rotating shaft 314 is output through the second output shaft 316. The second output shaft 316 drives the third synchronous pulley 317 to rotate. The third synchronous pulley 317 transmits power to two parallel or sequentially arranged fourth synchronous pulleys 319 through the second synchronous belt 318 on its outer wall. The outer walls of the two second driven gears 320 mesh with each other. This meshing method is usually used to transmit power to another shaft and may play a role in synchronization or changing direction. The output end of the second driven gear 320 near the downstream screening screen plate 2 is connected to the large driving gear 321 through the transmission shaft and drives it to rotate. The large driving gear 321 meshes with the large driven gear 322. This large gear transmission pair may be used to further transmit power or adjust the speed and torque. The large driving gear 321 is connected to the crushing auger 324 through its connecting shaft and drives the crushing auger 324 to rotate. The rotating crushing auger 324 agitates, crushes and pushes the material in the packaging bag that has been cut by the unpacking blades 315. The function of the crushing auger 324 is to further crush the material and effectively separate the material from the packaging bag fragments, so that the material can pass smoothly through the subsequent screening screen 2 and other structures.

[0030] It should be noted that this utility model is a fully automatic multi-layer bag unpacking machine. In use, firstly, the motor 302 starts, outputting power through the first output shaft 303. The first output shaft 303 is connected to the first synchronous pulley 304, causing the first synchronous pulley 304 to rotate. The first synchronous pulley 304 drives two second synchronous pulleys 307 to rotate via the first synchronous belt 306 on the outer wall. The output ends of the two second synchronous pulleys 307 are connected to a drive gear 308, so the drive gear 308 also begins to rotate. Secondly, the drive gear 308 meshes with the first driven gear 313, transmitting power to the first driven gear 313. Simultaneously, the drive gear 308 also transmits power through the connected rotating rod 309. The rotating rod 309 transmits power through the positioning block 310 connected to the outer wall. Multiple guide plates 311 rotate, and the packaging bag is fed from above the guide plate 1. The multiple guide plates 311 guide the falling material to avoid blockage and achieve uniform feeding. The second synchronous wheel 307, which is away from the active gear 308, transmits power to the rotating shaft 314 through the transmission shaft. The rotating shaft 314 drives the unpacking blades 315 on the outer wall to rotate. The unpacking blades 315 are used to cut the falling packaging bag. Then, the second output shaft 316 transmits the rotational kinetic energy of the rotating shaft 314. When the packaging bag is guided to the action area of ​​the unpacking blades 315, the rotating unpacking blades 315 will cut or tear the packaging bag, creating conditions for the subsequent material to fall. The rotational kinetic energy of the rotating shaft 314 is output through the second output shaft 316. The second output shaft 316 drives the third synchronous wheel 317 to rotate. The third synchronous wheel 317 transmits power to two parallel or sequentially arranged fourth synchronous wheels 319 through the second synchronous belt 318 on its outer wall. Then, the outer walls of the two second driven gears 320 mesh with each other. This meshing method is typically used to transmit power to another shaft and may serve to synchronize or change direction. The output end of the second driven gear 320, located near one end of the subsequent processing screen plate 2, is connected to the large driving gear 321 via a transmission shaft and drives it to rotate. The large driving gear 321 meshes with the large driven gear 322. This large gear transmission pair may be used to further transmit power or adjust the speed and torque. The large driving gear 321 is connected to the crushing auger 324 via its connecting shaft, driving the crushing auger 324 to rotate. The rotating crushing auger 324 agitates, crushes, and pushes the material inside the packaging bag that has been cut by the unpacking blades 315. The function of the crushing auger 324 is to further crush the material and effectively separate the material from the packaging bag fragments, allowing the material to pass smoothly through the subsequent screen plate 2 and other structures. Finally, after the crushed packaging bag and material are screened by the screen plate 2, the material falls to the bottom of the screen plate 2, and the packaging bag falls onto the screen plate 2.
