Description

[0002] In the prior art, an ordinary large-bag packaging machine consists of a single feeding hopper, a vibrating feeder, and a feeding pipeline. That is, the feeding speed is adjusted by regulating the vibration amplitude of the vibrating feeder. Before reaching the set weight for high-speed feeding, the vibration amplitude of the vibrating feeder is large and the feeding speed is fast; after reaching the weight of the high-speed feeding device, the vibration amplitude of the vibrating feeder decreases, the feeding speed decreases, and the feeding accuracy increases, and the weight of the large bag can be accurately controlled to the final set weight.

[0003] The disadvantages of the above solution are as follows: To prevent inaccurate weight of the large bag, it is necessary to ensure the low-speed feeding accuracy of the vibrating feeder, and the low-speed feeding is slow. Due to the limited vibration adjustment range of the vibrating feeder, the high-speed feeding speed is also very limited.

[0034] Wherein, the discharging part 7 has a first preset weight and a second preset weight. When the discharging part 7 is less than the first preset weight, the first pneumatic slide valve 44 is closed, the second pneumatic slide valve 45 and the third pneumatic slide valve 46 are opened and the rotary valve 6 is opened; when the discharging part 7 is greater than the first preset weight and less than the second preset weight, the second pneumatic slide valve 45 and the rotary valve 6 are closed, the first pneumatic slide valve 44 is opened and the vibrating feeder 5 is opened; when the discharging part 7 is greater than the second preset weight, the vibrating feeder 5, the third pneumatic slide valve 46 and the first pneumatic slide valve 44 are closed.

[0035] With the above structure and Figure 1 , those skilled in the art can connect the feeding part 1 and the discharging part 7, and then packaging can be carried out at the position of the discharging part 7.

[0036] Specifically, the feeding section 1 has an outlet side 11 for discharging the raw materials in the discharging section 1. A first hopper 2 and a second hopper 3 are connected to the outlet side 11. A connecting pipe 4 is connected to the ends of the first hopper 2 and the second hopper 3 away from the feeding section 1. The position of the connecting pipe 4 away from the first hopper 2 and the second hopper 3 is fixedly connected to the discharging section 7. The above structure can stably connect the feeding section 1 and the discharging section 7, thereby achieving the purpose of packaging the raw materials as described above.

[0037] Further, those skilled in the art have made further settings to the connecting pipe 4. According to Figure 1 , the connecting pipe 4 is provided with a first inlet end 41 and a second inlet end 42 respectively connected to the first hopper 2 and the second hopper 3. That is, the first inlet end 41 is connected to the end of the first hopper 2 away from the feeding section 1, and the second inlet end 42 is connected to the end of the second hopper 3 away from the feeding section 1. The connecting pipe 4 is also provided with an outlet end 43 for connecting to the discharging section 7.

[0038] In the above settings, a first pneumatic slide valve 44 is installed near the first inlet end 41, a second pneumatic slide valve 45 is installed near the second inlet end 42, and a third pneumatic slide valve 46 is installed near the outlet end 43.

[0039] With the above structure, the opening and closing of the first inlet end 41, the second inlet end 42, and the outlet end 43 can be controlled. It should be noted that in this embodiment, those skilled in the art have also connected a rotary valve 6 between the second pneumatic slide valve 45 and the discharging section 7, and a vibrating feeder 5 is arranged between the first pneumatic slide valve 44 and the discharging section 7.

[0040] According to Figure 1 , the connecting pipe 4 is specifically Y-shaped, that is, there is a connection point in the middle of the connecting pipe 4. In the above settings, the rotary valve 6 is arranged between the second pneumatic slide valve 45 and the connection point, and the vibrating feeder 5 is arranged between the first pneumatic slide valve 44 and the connection point.

[0041] With the above structure, those skilled in the art can set the discharging section 7 to have a first preset weight and a second preset weight. Specifically, when the discharging section 7 is less than the first preset weight, the first pneumatic slide valve 44 is closed, the second pneumatic slide valve 45 and the third pneumatic slide valve 46 are opened and the rotary valve 6 is opened. That is, the raw materials in the feeding section 1 can be discharged into the connecting pipe only through the second hopper 3, and the raw materials are discharged into the discharging section 7 through the connecting pipe for packing.

[0042] When the weight of the discharging section 7 is greater than the first preset weight and less than the second preset weight, the second pneumatic slide valve 45 and the rotary valve 6 are closed, the first pneumatic slide valve 44 is opened, and the vibrating feeder 5 is opened. In the above-mentioned situation, it can be set that the raw materials are transported only through the first hopper 2, and the raw materials are discharged into the discharging section 7 through the connecting pipe for packing.

[0043] When the weight of the discharging section 7 is greater than the second preset weight, the vibrating feeder 5, the third pneumatic slide valve 46 and the first pneumatic slide valve 44 are closed. That is, when the weight of the discharging section 7 is greater than the second preset weight, the first hopper and the second hopper stop discharging raw materials continuously.

[0044] By setting the first preset weight and the second preset weight, and through the first hopper and the second hopper, the raw materials in the feeding section 1 can be gradually transported into the discharging section 7 for packing according to steps. When the weight of the discharging section 7 is greater than the second preset weight, the raw materials are no longer discharged into the discharging section 7 for packing.

[0045] It can be understood that in the above setting, the second preset weight is greater than the first preset weight. When the weight of the discharging section 7 is greater than the second preset weight, the vibrating feeder 5, the third pneumatic slide valve 46 and the first pneumatic slide valve 44 are closed in sequence, so that the overall packing can be stably stopped.

By arranging the first hopper 2 and the second hopper 3 in parallel, the discharging mode can be switched according to the actual situation, and there is no need to replace the hopper again.

[0048] In the above setting, preferably, the maximum inner diameter of the first hopper 2 is less than the maximum inner diameter of the second hopper 3. That is, when the weight of the discharging section 7 is less than the first preset weight, the second hopper 3 is used for rapid discharging. When the weight of the discharging section 7 is greater than the first preset weight and less than the second preset weight, the first hopper 2 is used for slow discharging.

[0049] During the slow discharging process, the vibrating feeder is used to assist in discharging, so that the raw materials can be stably transported to the discharging section 7.

[0050] Preferably, the feeding part 1 is further provided with an exhaust port 12 and a feeding port 13.

The air pressure inside the packaging machine can be balanced through the exhaust port 12. Among them, the filtering part 14 arranged in the feeding part can filter the conveyed air.

[0052] That is, in the process of pneumatically conveying the powder coating resin, the conveying air is discharged through the filtering part 14. Among them, the filtering part can be set as a bag-type resin filter.

[0053] In the connection structure of the above connecting pipe 4, preferably, both ends of the vibratory feeder 5 are flexibly connected to the connecting pipe 4, and the connecting pipe 4 is flexibly connected to the third pneumatic slide valve 46. Furthermore, it can effectively avoid the breakage or detachment of the connection part of the connecting pipe 4 due to the vibration of the connecting pipe 4 during operation, thereby improving the stability of the connection of the connecting pipe 4.

Lugs are installed on the parts of the plurality of bag-tipping cylinders 74 inside the outer frame, and the lugs are connected to the large bag, so that the plurality of bag-tipping cylinders lift and lower the large bag regularly.

[0055] That is, in the discharging part, those skilled in the art can set it to have an outer frame to protect the packaging of the raw material. By setting the connecting part 72 on the outer frame 7, the large bag for packaging can be fixed. During the process of conveying the raw material after fixing the large bag, a plurality of bag-tipping cylinders 74 can continue to be installed on the top of the outer frame 7.
