DETAILED DESCRIPTION
[0015] The technical solutions in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model.
[0016] Referring to Figure 1 A mother particle quantitative sub-packaging equipment comprises a storage box 1, a first weighing box 3, a discharging device 2, a second weighing assembly and a third weighing assembly, the discharging device 2 can convey the material in the storage box 1 to the first weighing box 3, the first weighing box 3 is communicated with a discharging port 8, and a fourth switch valve 11 is arranged between the first weighing box 3 and the discharging port 8, the first weighing box 3 releases the material to the discharging port 8 when the weight meets the qualified value, the first weighing box 3 releases the material to the second weighing assembly when the weight is greater than the qualified value, and the second weighing assembly performs a material reduction operation, and the first weighing box 3 releases the material to the third weighing assembly when the weight is less than the qualified value, and the third weighing assembly performs a material feeding operation.
[0017] Referring to Figure 1The device first stores the master batch in the storage tank, and then sends it to the first weighing tank through the feeding device. The first weighing tank detects the weight of the obtained material in real time, compares it with the preset qualified value, and makes three responses:
[0018] When the weighing result is just in the qualified interval, the fourth switch valve is immediately opened, and the material directly flows into the feeding port to complete the packaging, thereby saving the subsequent processing steps and maintaining the fastest production rhythm.
[0019] When the weighing result is overweight, the first weighing tank guides all the material to the second weighing assembly. The assembly starts the material reduction operation to quickly return the excess master batch to the system, so that the weight of the material is accurately returned to the target value. At the same time, the first weighing tank receives the next batch of material, and the whole process does not affect each other.
[0020] When the weighing result is underweight, the first weighing tank guides all the material to the third weighing assembly. The assembly supplements the insufficient part through the feeding operation and then sends it to the feeding port; at the same time, the first weighing tank also continues to receive the material at a high speed during the feeding, ensuring that the main process is not interrupted.
[0021] This working mode of "main weighing - error diversion - parallel correction" combines the three actions of weighing, feeding and reducing: the weighing correction is carried out in parallel with the next weighing, eliminating the waiting bottleneck of traditional devices during feeding or reducing, significantly shortening the single-bag packaging period, and improving the overall production capacity. Error processing is completed in the dedicated second and third weighing assemblies, avoiding frequent start and stop of the main weighing channel, reducing mechanical wear and improving weighing stability.
[0022] As an embodiment, the second weighing assembly includes a second weighing tank 6, the second weighing tank 6 is in communication with the first weighing tank 3, and the first switch valve 5 is arranged between the two. A material reduction device 4 is arranged between the second weighing tank 6 and the storage tank 1, and the material reduction device 4 can send the material in the second weighing tank 6 into the storage tank 1. The second weighing tank 6 is in communication with the feeding port 8, and the second switch valve 7 is arranged between the two.
[0023] When the weight of the material in the first weighing tank exceeds the set qualified value, the system controls the first switch valve to open, and the entire material in the first weighing tank is discharged into the second weighing tank. At this time, the first weighing tank is in an empty state, and can immediately prepare to receive the next batch of material, avoiding affecting the continuity of the main weighing process due to waiting for material reduction.
[0024] After the second weighing tank receives the material, it judges the weight to be reduced according to the weighing result, and sends the excess part back to the storage tank through the material reduction device until the remaining material meets the qualified value. Subsequently, the qualified material in the second weighing tank can be sent to the feeding port for packaging. This process realizes the rapid transfer and accurate reduction of overweight, and at the same time maintains the high-speed circulation of the main weighing tank to receive the material, thereby effectively improving the packaging efficiency of the whole device.
[0025] As an embodiment, the third weighing assembly comprises a third weighing tank 10, which is in communication with the first weighing tank 3 and has a fifth switch valve 12 therebetween, and is provided with a material supplementing device 13 between the third weighing tank 10 and the material storage tank 1, which is capable of sending the material in the material storage tank 1 into the third weighing tank 10, and the third weighing tank 10 is in communication with the material outlet 8 and is provided with a third switch valve 9 therebetween.
[0026] In this embodiment, when the weight of the material in the first weighing tank is lower than the set qualified value, the system controls the fifth switch valve to open, and the material in the first weighing tank is discharged into the third weighing tank. After the third weighing tank receives the part of the material, the current weight is detected by weighing, and the appropriate amount of material is transported from the material storage tank into the third weighing tank by the material supplementing device for supplementing until the total weight reaches the qualified value.
[0027] After the supplementing is completed, the third switch valve is opened to release the qualified material in the third weighing tank to the material outlet for packaging. During the whole process, the first weighing tank can start to receive the next batch of material in the empty state, so as to ensure that the main weighing process is not interrupted. The process completes the supplementing process through the third weighing tank, realizes the rapid correction under the condition of insufficient weighing, and improves the operation efficiency and continuous operation ability of the whole equipment.
[0028] As an embodiment, the whole system is connected to a controller, and the material outlet device 2, the first weighing tank 3, the material reducing device 4, the first switch valve 5, the second weighing tank 6, the second switch valve 7, the material outlet 8, the third switch valve 9, the third weighing tank 10, the fourth switch valve 11, the fifth switch valve 12, and the material supplementing device 13 are connected to the controller.
