Description

Technical Field

[0001] This utility model relates to the field of down processing technology, specifically to a down grading device for down garment production. Background Technology

[0002] Down jackets are outer garments filled with down feathers, and they have a large, rounded shape. Down jackets generally contain more than half duck down, and may also contain some small feathers. The duck down is cleaned, sterilized at high temperatures, and then used to fill the garment, resulting in a down jacket. Down jackets have good warmth retention.

[0003] In down production, raw materials, including feathers and down feathers, are mixed together. Before entering the processing equipment, they need to undergo pretreatment to separate the feathers and down feathers. Down feathers enter the equipment, while feathers are processed separately. Previously, without dedicated separation equipment, workers manually sorted the feathers off the conveyor belt, which was not only time-consuming and labor-intensive but also failed to completely separate the feathers, affecting the quality of the down products. Furthermore, different grades of down have different unit prices, necessitating grading of the down according to customer requirements.

[0004] In the prior art, patent document CN210321063U discloses a down sorting machine. In this technical solution, the down is first dispersed using an agitator before passing through a dryer, preventing it from sticking together and avoiding unnecessary problems caused by static electricity. The sorting process involves multi-stage separation, with a fan blowing the down into a sorting chamber shaped like an inverted cone funnel for easy collection. This technical solution utilizes air separation technology to classify down into different grades. The main principle is that different grades of down have different weights; during air separation, broken down feathers are blown the furthest, while other grades land closer to the air source. Therefore, this equipment is relatively long and occupies a large area.

[0005] Patent document CN210916374U discloses a down grading device for down jacket production. Driven by a motor, the device rotates a rotating box via a rotating rod. The rotating box disperses the down inside, which enters a dispersing chamber. The inner wall of the dispersing chamber is fixedly connected with elastic padding to reduce impact and protect the down. Driven by a fan, the down is blown to the bottom of the dispersing chamber. Under the action of a blower, the down moves along the spiral blades and is discharged from the outlet pipe. Due to the different qualities of the down, the lighter, higher-quality down is discharged first, facilitating grading and collection. This technical solution, by causing the down to move upwards, effectively reduces the floor space required for air separation of different grades of down. However, the down remaining in the grading box clogs the isolation mesh, which in turn affects the upward airflow, reducing the grading effect in the later stages. Moreover, when the down is broken up, it is only by the down thrown out of the rotating box hitting the elastic pad that the down is broken up, resulting in a weak down breaking effect. Utility Model Content

[0006] The main purpose of this invention is to provide a down grading device that is small in overall size, reduces the floor space required, and facilitates the grading of down of different grades.

[0007] To achieve the above objectives, the technical solution provided by this utility model is as follows: A down grading device for down garment production includes a housing, within which a dispersing cylinder is concentrically fixed. The upper end of the dispersing cylinder extends above the housing, and a feed pipe is fixed to the upper end of the dispersing cylinder. A dispersing component is disposed inside the dispersing cylinder. A guide cone sleeve is fixed inside the housing below the dispersing cylinder, with its upper end extending into the lower end of the dispersing cylinder. A discharge component is disposed between the guide cone sleeve and the lower end of the dispersing cylinder, capable of intermittently releasing down from the dispersing cylinder. Multiple arc-shaped grooves are evenly distributed around the outer circumference of the guide cone sleeve below the dispersing cylinder, and filter screens are fixed within the arc-shaped grooves. The bottom plate of the housing bulges upward in the middle, and the guide cone sleeve is fixed in the middle of the bottom plate of the housing. At the upper end of the shell, a mounting cavity is formed in the lower middle of the bottom plate. A storage ring cavity is formed on the inner and outer sides of the lower end of the shell. A fan is fixed in the mounting cavity. The air outlet of the fan is connected to the inside of the guide cone sleeve. A ring pipe is fixed in the mounting cavity. Multiple inner tubes are evenly distributed and fixed in the circumference of the storage ring cavity. One end of the inner tube in the storage ring cavity is sealed. Multiple outlet holes are opened in the inner tube in the storage ring cavity. The other end of the inner tube is fixedly connected to the ring pipe. An air inlet pipe is fixedly connected to the ring pipe. A spiral blade is fixed between the dispersing cylinder and the inner wall of the shell. The spiral blade forms a spiral channel between the dispersing cylinder and the shell. The upper end of the spiral channel is connected to the discharge pipe fixed at the upper end of the shell.

[0008] Specifically, the dispersing component includes a vertical sleeve concentrically fixed to the upper end of the guide cone sleeve, a lower motor fixed inside the vertical sleeve, the output shaft of the lower motor passing through the upper end of the vertical sleeve, the output shaft of the lower motor being rotatably connected to the upper end of the vertical sleeve through a sealed bearing, and multiple dispersing rods fixed on the output shaft of the lower motor above the vertical sleeve.

[0009] Specifically, an upper motor is concentrically fixed at the upper end of the dispersing cylinder, and the output shaft of the upper motor extends into the dispersing cylinder. The output shaft of the upper motor is rotatably connected to the upper end of the dispersing cylinder through a sealed bearing. A swing cylinder is concentrically arranged inside the dispersing cylinder. The swing cylinder is located above the dispersing assembly and is concentrically fixed to the output shaft of the upper motor. The down discharged from the feed pipe can fall into the swing cylinder. Multiple vertical grooves are opened on the lower part of the side wall of the swing cylinder.

[0010] Specifically, an upper conical sleeve is fixed inside the dispersing cylinder below the throwing cylinder, and the diameter of the upper end of the upper conical sleeve is larger than the diameter of the lower end.

[0011] Specifically, the feeding assembly includes a lower conical sleeve, the upper diameter of which is larger than the lower diameter. The upper end of the lower conical sleeve slides in contact with the inner edge of the wall of the dispersing cylinder. The upper end of the guide conical sleeve is located inside the lower end of the lower conical sleeve and contacts the lower end of the lower conical sleeve. Multiple fixing plates are fixed at the lower end of the dispersing cylinder, and vertical telescopic rods are fixed on each fixing plate. The telescopic ends of the telescopic rods are fixedly connected to the lower conical sleeve.

[0012] Specifically, multiple vibrators are fixed on the outer wall of the lower conical sleeve.

[0013] Specifically, the telescopic rod is an electric telescopic rod, and the telescopic rod, vibrator, and controller are electrically connected.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows: 1. The dual dispersing mechanism of the spinning tube and the dispersing rod ensures that the down is fully dispersed and avoids clumping. The addition of an upper conical sleeve guide structure allows the down to impact the tube wall a second time after being dispersed, further improving the dispersing efficiency per pass and reducing residual down clumps.

[0015] 2. Utilizing an airflow system consisting of a fan, an arc-shaped filter, and a spiral channel, lighter down feathers rise with the airflow and are discharged, while heavier down feathers fall and are collected. The fan speed is adjustable, enabling multi-stage air separation, such as first removing loose down feathers and then collecting down feathers of different weights in stages, thus improving the precision of the grading and the purity of the down feathers.

[0016] 3. The feeding component enables intermittent release of down, avoiding accumulation caused by a single drop; a vibrator is added to assist in the down's descent, ensuring that the down is evenly dispersed on the outside of the guide cone sleeve, improving the thickness consistency and airflow effect during air separation.

[0017] 4. The guide cone sleeve, spiral blades and material storage ring cavity are integrated to form a closed-loop system. The air flows through the spiral channel and rotates upward to be discharged. The material storage ring cavity is designed with ring pipe and inner pipe to support secondary air separation. After the blower blows up the material, it is sorted again, reducing manual intervention and realizing continuous automated production. Attached Figure Description

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0024] Example 1: Refer to Figures 1-4 As shown, a down grading device for down garment production includes a housing 1, a dispersing cylinder 2 concentrically fixed inside the housing 1, the upper end of the dispersing cylinder 2 extending above the housing 1, and a feed pipe 4 fixed to the upper end of the dispersing cylinder 2.

[0025] A guide cone sleeve 19 is fixed inside the shell 1 below the dispersing cylinder 2. The upper end of the guide cone sleeve 19 extends into the lower end of the dispersing cylinder 2. A discharge assembly is provided between the guide cone sleeve 19 and the lower end of the dispersing cylinder 2. The discharge assembly can intermittently release the down in the dispersing cylinder 2.

[0026] The dispersing cylinder 2 is equipped with a dispersing component.

[0027] The disintegration assembly includes a vertical sleeve 12 concentrically fixed to the upper end of the guide cone sleeve 19. A lower motor 13 is fixed inside the vertical sleeve 12. The output shaft of the lower motor 13 passes through the upper end of the vertical sleeve 12. The output shaft of the lower motor 13 is rotatably connected to the upper end of the vertical sleeve 12 through a sealed bearing. Multiple disintegration rods 14 are fixed on the output shaft of the lower motor 13 above the vertical sleeve 12.

[0028] An upper motor 3 is concentrically fixed at the upper end of the dispersing cylinder 2. The output shaft of the upper motor 3 extends into the dispersing cylinder 2. The output shaft of the upper motor 3 is rotatably connected to the upper end of the dispersing cylinder 2 through a sealed bearing. A spinning cylinder 9 is concentrically arranged inside the dispersing cylinder 2. The spinning cylinder 9 is located above the dispersing assembly. The spinning cylinder 9 is concentrically fixed to the output shaft of the upper motor 3. The down discharged from the feed pipe 4 can fall into the spinning cylinder 9. Multiple vertical grooves 10 are opened on the lower part of the side wall of the spinning cylinder 9.

[0029] The feeding assembly includes a lower cone sleeve 15, the upper diameter of which is larger than the lower diameter. The upper end of the lower cone sleeve 15 slides in contact with the inner edge of the wall of the dispersing cylinder 2. The upper end of the guide cone sleeve 19 is located inside the lower end of the lower cone sleeve 15 and contacts the lower end of the lower cone sleeve 15. Multiple fixing plates 17 are fixed at the lower end of the dispersing cylinder 2. Vertical telescopic rods 16 are fixed on each fixing plate 17. The telescopic ends of the telescopic rods 16 are fixedly connected to the lower cone sleeve 15.

[0030] Multiple arc-shaped grooves 20 are evenly distributed on the outer circumference of the guide cone sleeve 19 below the dispersing cylinder 2, and a filter screen is fixed in the arc-shaped groove 20.

[0031] The bottom plate of housing 1 protrudes upward in the middle, and the guide cone sleeve 19 is fixed to the upper middle part of the bottom plate of housing 1. The diameter of the lower end of the guide cone sleeve 19 is larger than the diameter of the upper end. An installation cavity 24 is formed in the lower middle part of the bottom plate of housing 1, and a material storage ring cavity 25 is formed on the inner and outer sides of the lower end of housing 1. A fan 6 is fixed in the installation cavity 24, and the air outlet of the fan 6 is connected to the inside of the guide cone sleeve 19.

[0032] An annular tube 7 is fixed inside the mounting cavity 24. Multiple inner tubes 21 are evenly distributed and fixed inside the storage annular cavity 25. One end of the inner tube 21 inside the storage annular cavity 25 is sealed. Multiple outlet holes 22 are opened in part of the inner tube 21 inside the storage annular cavity 25. The other end of the inner tube 21 is fixedly connected to the annular tube 7. An air inlet pipe 8 is fixedly connected to the annular tube 7.

[0033] A spiral blade 23 is fixed between the dispersing cylinder 2 and the inner wall of the shell 1. The spiral blade 23 forms a spiral channel between the dispersing cylinder 2 and the shell 1. The upper end of the spiral channel is connected to the discharge pipe 5 fixed at the upper end of the shell 1.

[0034] When this device is working, down enters the spinning drum 9 through the feed pipe 4. The upper motor 3, lower motor 13, and fan 6 are started. The upper motor 3 drives the spinning drum 9 to rotate. Under centrifugal force, the down inside the spinning drum 9 is thrown out from the vertical groove 10 and impacts the inner wall of the dispersing cylinder 2, thus achieving the first dispersal of the down. After the lower motor 13 starts, it drives the dispersing rod 14 to rotate, which can further disperse the down inside the dispersing cylinder.

[0035] After being dispersed twice, the down feathers fall between the lower cone sleeve 15 and the guide cone sleeve 19. The telescopic rod 16 is activated, causing the lower cone sleeve 15 to move upwards with a gap. As the lower cone sleeve 15 moves upwards, a gap is created between it and the guide cone sleeve 19. The down feathers pass through this gap and fall dispersed under the guidance of the guide cone sleeve 19. After the upper cone sleeve 11 returns to its original position, the down feathers stop moving downwards.

[0036] After the blower 6 is started, the air passes through the arc groove 20 and rotates upward in the spiral channel and is discharged from the discharge pipe 5. The down that slides down along the outer edge of the guide cone sleeve 19 can be blown by the air discharged from the arc groove 20. The lighter down moves with the air and is finally discharged from the discharge pipe 5, while the heavier down falls into the storage ring cavity 25.

[0037] In this embodiment, when air separation begins, the airflow of the blower 6 is set to the minimum level to first separate the loose down feathers. When further air separation of the down is required, the blower is connected to the air inlet pipe 8, allowing air to be discharged from the outlet 22. This blows up the down feathers in the storage ring cavity 25, and then the airflow of the blower 6 is increased to perform a second air separation of the down feathers in the storage ring cavity 25. By sequentially increasing the airflow of the blower 6, the down feathers can be graded and air-separated.

[0038] Example 2: Based on Example 1, referring to... Figure 3 As shown, an upper conical sleeve 11 is fixed inside the dispersing cylinder 2 below the throwing cylinder 9. The diameter of the upper end of the upper conical sleeve 11 is larger than the diameter of the lower end.

[0039] After the down feathers impact the inner wall of the dispersing cylinder 2, they gather towards the center of the dispersing cylinder 2 under the guidance of the upper conical sleeve 11 and are discharged from the lower end of the upper conical sleeve 11. When the dispersing rod 14 disperses the down feathers discharged from the lower end of the upper conical sleeve 11, it causes the down feathers to move towards the inner wall of the dispersing cylinder 2, allowing the down feathers to impact the inner wall of the dispersing cylinder 2 a second time. That is, during the rotation of the dispersing rod 14, the down feathers are dispersed again under the action of centrifugal force, further improving the dispersing effect of the down feathers.

[0040] Example 3: Based on Example 1, referring to... Figure 3 As shown, multiple vibrators 18 are fixed on the outer wall of the lower conical sleeve 15. The telescopic rod 16 is an electric telescopic rod 16, and the telescopic rod 16, vibrators 18 and controller are electrically connected.

[0041] When the telescopic rod 16 drives the lower cone sleeve 15 to move upward, the controller starts the vibrator 18. During the vibration of the vibrator 18, the down can be dispersed and fall, avoiding the accumulation of down during the process of sliding and dispersing outside the guide cone sleeve 19. That is, during the process of the down sliding and dispersing outside the guide cone sleeve 19, the uniformity of down thickness can be improved, which makes it easier for the air discharged from the arc groove 20 to perform air separation on the down.

[0042] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
