Description

Technical Field

[0001] The invention relates to the technical field of down suction devices, and in particular to a dust-free down suction device for down products. Background Art

[0002] The down suction device is a special equipment that uses the negative pressure principle to achieve down adsorption, transportation, collection and processing. It is widely used in down processing, clothing manufacturing, home textile production and other fields. In the down product production line, the down suction device can "suck" the down from the storage bin through the pipe and transport it to the filling machine, sewing machine, filling equipment and other downstream stations, thereby avoiding scattering and loss caused by manual handling. At the same time, non-contact transportation is achieved through airflow control, which is suitable for the fluffy and light characteristics of down, and also avoids down damage or agglomeration caused by mechanical extrusion.

[0003] When in use, the existing down suction device lacks measures for dealing with the down attached to the inner wall of the conveying tube, and also lacks a mechanism for adaptively adjusting the processing strength according to the humidity of the down. As the down suction operation continues, down will continue to adhere to the inner wall of the conveying tube. These down will affect the airflow in the tube and reduce the down suction efficiency. The attached down has different humidity and different adhesion to the tube wall, so the required processing strength is also different. At the same time, in terms of impurity treatment, the existing technology is also difficult to effectively control the impurities in the down material, which will affect the quality of the subsequently processed down products. For the removal of impurities, corresponding adaptive adjustment measures are also needed, so that the device can automatically adjust the impurity removal strength according to the humidity of the conveyed down. In the process of conveying the down material, down clumps are also prone to aggregation. The size of the groups that can be gathered by down with different humidity and the adhesion strength to each other are also different, which also requires corresponding solutions.

[0015] Compared with the prior art, the technical solution provided by the present invention has the following beneficial effects:

[0016] 1. The present invention is capable of adaptively adjusting the working power of the ventilation fan by setting up an adaptive ventilation and anti-down component, wherein the humidity sensor installed on the inner wall of the No. 1 conveying pipe monitors the humidity in the pipe in real time. When the humidity changes, the data is transmitted to the PLC controller. The PLC controller controls the wind speed of the ventilation fan according to a preset program. When the humidity is high, the ventilation fan increases the wind speed and sends air into the pipe through multiple air outlets on the air outlet pipe, and then cooperates with the rotating component to remove the down attached to the inner wall of the pipe by wind force. At the same time, it can also increase air circulation, effectively prevent down material from accumulating and clogging in the pipe due to moisture, and improve conveying efficiency.

[0017] 2. The present invention is capable of achieving efficient separation of impurities in down materials by providing an adaptive impurity removal component. The electric push rod is extended and retracted according to the instructions of the PLC controller, and drives the No. 3 conveying pipe to swing up and down to a certain extent through the moving block and the No. 1 connecting rod. During the shaking process, the down material in the No. 3 conveying pipe moves relative to the pipe wall. Due to the effects of gravity and inertia, impurities are more likely to fall into the collecting box through the multiple filter holes on the lower end face of the No. 3 conveying pipe. This adaptive impurity removal method can flexibly adjust the propulsion stroke, i.e., the impurity removal force, of the electric push rod through the PLC controller according to the humidity of the down material, thereby achieving efficient impurity removal, effectively improving the purity of the down material, and laying the foundation for the subsequent high-quality production of down products.

[0018] 3. The present invention is capable of achieving efficient breaking up of down balls by providing an adaptive down ball breaking component. When the electric push rod pushes the moving block to move, the connecting block drives the conductive ring to slide on the variable resistance rod, changes the circuit resistance, and thus controls the speed of the No. 2 motor. The No. 2 motor drives the sliding rod and the breaking frame to move back and forth up and down in the No. 3 conveying pipe through the No. 2 turntable and the No. 2 connecting rod. The movement speed can be automatically adjusted according to the humidity of the down material. For down balls with high humidity, large aggregation and tighter density, the speed of the No. 2 motor is accelerated, and the breaking frame will break them up at a higher frequency. For down balls with low humidity, small aggregation and looser density, the speed is reduced, which can avoid damage to the down fibers caused by excessive breaking up. Compared with the traditional fixed speed breaking method, this adaptive breaking method can more accurately process down balls in different states, ensure the uniformity of the down material, and improve the filling quality and thermal insulation performance of down products.

The disassembly frame 610 is located in the No. 3 conveying pipe 17.

[0037] The working principle of the present invention is as follows: when absorbing down, the input end of the No. 1 conveying pipe 13 is extended into the area to be absorbed down, and then the duct exhaust fan 12 is started. After the duct exhaust fan 12 starts working, negative pressure suction is formed in the entire down material conveying channel. Under the action of negative pressure, the external down material first enters the device through the No. 1 conveying pipe 13. The humidity sensor 21 on the inner wall of the No. 1 conveying pipe 13 monitors the humidity of the down material in the pipe in real time. At the same time, the humidity sensor 21 converts the humidity signal into an electrical signal and feeds it back to the PLC controller 22. The PLC controller 22 receives the humidity signal and feeds it back to the PLC controller 22. After receiving the signal, the command is immediately issued according to the preset program to control the ventilation fan 23 to work, and the wind speed of the ventilation fan 23 is adjusted according to the humidity. The greater the humidity of the velvet material, the greater the wind speed provided by the ventilation fan 23. After the ventilation fan 23 is started, the air is blown into the No. 1 conveying pipe 13, the rotating conveying pipe 15 and the No. 2 conveying pipe 14 from the air outlet 26 through the air supply pipe 24 and the air outlet pipe 25. Through continuous airflow, the air circulation in the pipeline is guaranteed to prevent the accumulation and blockage in the pipeline due to the high humidity of the velvet material. The ventilation fan 23 and the pipeline exhaust fan 12 work At the same time, the No. 1 motor 31 is started, and the No. 1 rotating shaft 32 at its output end begins to rotate, and the No. 1 gear 33 at the side end of the No. 1 rotating shaft 32 rotates accordingly. Since the No. 1 gear 33 is meshed with the No. 2 gear 34 circumferentially fixedly connected to the rotating conveying pipe 15, the rotation of the No. 1 gear 33 drives the No. 2 gear 34 to rotate, thereby realizing the rotation of the rotating conveying pipe 15. The air supply pipe 24 and the air outlet pipe 25 will rotate along with the rotating conveying pipe 15. Therefore, the air outlet 26 of the air outlet pipe 25 will also rotate in the No. 1 conveying pipe 13 and the No. 2 conveying pipe 15 when discharging air. The delivery pipe 14 makes a circular motion. During the transportation process, the fluff will adhere to the inner wall of the pipe due to humidity and other reasons. The air outlet pipe 25 and the delivery pipe rotate relative to each other, so that the wind can blow away the fluff attached to the inner wall of the No. 1 delivery pipe 13 and the No. 2 delivery pipe 14, thereby effectively preventing the accumulation and adhesion of the fluff inside the pipe. At the same time, the wind force can be adaptively adjusted according to the humidity of the fluff, which is more in line with actual use needs. In addition, the operation through wind power can also reduce the humidity of the fluff in the pipe, which is more conducive to the subsequent delivery of the fluff.

[0038] When the No. 1 rotating shaft 32 rotates, the driving wheel 51 circumferentially fixedly connected to the No. 1 rotating shaft 32 will also rotate synchronously, and the driving wheel 51 transmits power to the driven wheel 52 circumferentially fixedly connected to the No. 2 rotating shaft 42 through the transmission belt 53. The driven wheel 52 drives the No. 2 rotating shaft 42 to rotate. When the No. 2 rotating shaft 42 rotates, the No. 1 turntable 43 will also rotate accordingly. The velvet passes through the rotating conveying pipe 15 and the No. 2 conveying pipe 14 and enters the No. 3 conveying pipe 17 under the suction of the duct exhaust fan 12. At this time, the PLC controller 22 controls the operation of the electric push rod 45 through a preset program according to the signal provided by the humidity sensor 21, thereby determining the propulsion stroke of the electric push rod 45. The greater the humidity of the velvet material, the greater the impurity removal force required, because the greater the adhesion between the impurities and the fluff, the greater the propulsion stroke of the electric push rod 45. The longer the range, the farther the moving block 47 is from the center of the No. 1 turntable 43. Therefore, under the condition that the speed of the No. 1 motor 31 is fixed, the up and down movement amplitude of the No. 3 conveying pipe 17 is greater, and the impurity removal force and frequency are also greater. When the No. 1 turntable 43 rotates, it will drive the electric push rod 45 and the moving block 47 to perform circular motion. The moving block 47 drives the No. 3 conveying pipe 17 to rock back and forth up and down through the No. 1 connecting rod 48. During the rocking process of the No. 3 conveying pipe 17, the velvet material in the pipe moves relative to the pipe wall. The mixed impurities, such as feather stems, dander, dust particles, etc., are more likely to fall into the collecting box 49 below through the multiple filter holes 410 provided on the lower end surface of the No. 3 conveying pipe 17 due to the effects of gravity and inertia, thereby achieving effective separation of impurities in the velvet material and improving the purity of the velvet material.

[0039] In the process of the electric push rod 45 pushing the moving block 47 to move, the connecting block 64 fixedly connected to the side wall of the moving block 47 will slide in the through groove 63, and the connecting block 64 drives the conductive ring 65 to slide on the variable resistance rod 62, thereby changing the circuit resistance. Since the conductive ring 65 is electrically connected to the No. 2 motor 66, the change in resistance will cause the current passing through the No. 2 motor 66 to change, thereby controlling the speed of the No. 2 motor 66. When the No. 2 motor 66 rotates, the No. 2 turntable 67 at its output end rotates accordingly. The No. 2 turntable 67 drives the slide bar 69 to move up and down in the No. 3 conveying pipe 17 through the No. 2 connecting rod 68, and the dismantling frame 610 at the bottom of the slide bar 69 will also rotate synchronously When the down material is relatively wet and the gathered down balls are relatively large and compact, the electric push rod 45 has a relatively large advancement stroke, the conductive ring 65 slides a relatively long distance on the variable resistance rod 62, the circuit resistance is relatively small, and the speed of the second motor 66 is accelerated. Therefore, the breaking frame 610 breaks up the down balls at a faster frequency. Similarly, when the down material is relatively wet and the gathered down balls are relatively small and loose, the speed of the second motor 66 is slowed down, and the breaking frame 610 breaks up the down balls at a lower frequency. Through the adaptive adjustment measures, it is possible to effectively avoid excessive breaking up and damaging the down fibers, achieve adaptive breaking up of the down balls, and ensure the uniformity of the down material.

[0040] The down material processed by the adaptive impurity removal component 4 and the adaptive down ball breaking component 6 enters the filter bag 110 in sequence through the No. 3 conveying pipe 17, the No. 2 corrugated hose 18, and the material conveying pipe 19 under the continuous suction of the duct exhaust fan 12. When the down material moves in the filter bag 110, the large-volume down has a large mass. When the airflow passes through the filter material, it is easier to move along the airflow direction due to inertia. Small dust has a small mass and is easily blocked by the filter material fibers to change its movement trajectory and will be intercepted, thereby achieving further dust removal for the down material. The pure down material after filtration enters the collection box 111 for collection. When the down material is needed later, it can be discharged through the discharge pipe 112 for subsequent processing such as filling and sewing of down products.

Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein.
