Description

Technical Field

[0001] This invention belongs to the field of down processing technology and relates to a down processing and washing device. Background Technology

[0002] In the production of down products, the raw down must undergo thorough cleaning to remove impurities such as grease and dust. Traditional down cleaning typically involves two main steps: soaking and rubbing. Soaking aims to fully wet the down and initially separate attached substances, while rubbing is used to deeply remove stubborn stains. However, in traditional operations, soaking and rubbing are often performed on different equipment or at different workstations, resulting in problems such as process interruptions, cumbersome down transfer, easy down loss, and low overall efficiency.

[0003] Patent CN114277449B discloses a down cleaning device and method, comprising a water tank, a lifter, an openable container assembly, and a washing assembly. The openable container includes a container base and a T-shaped seat connected thereto. The lifter includes a raised platform connected to the T-shaped seat and an auxiliary platform welded to the rear end of the water tank. The washing assembly includes a side platform fixedly installed on the left end of the water tank and two rows of horizontally sliding brushes. This device can simultaneously perform soaking and washing of down, resulting in a thorough and clean cleaning effect. Furthermore, it requires minimal manual intervention throughout the cleaning process, thus saving labor.

[0004] However, the aforementioned device has the following shortcomings in actual use: It is immersed in water, while brushing takes place in the air after being removed from the water. Brushing relies mainly on the scraping action between the bristles and the surface of the down to remove stains, making it difficult to effectively clean the tangled down inside, resulting in insufficient and incomplete cleaning of the down. The cleaning efficiency has potential for improvement. Secondly, during the process of lifting the down out of the liquid, there is a lack of effective sealing measures, allowing the down to still come into contact with and carry floating grease from the liquid surface, leading to secondary contamination.

[0005] To address the above problems, this invention proposes a down processing and washing device. Summary of the Invention

[0006] To address the problems existing in the background art, the present invention proposes a down processing and washing device.

[0007] To achieve the above objectives, the technical solution adopted by the present invention is as follows: A down processing and washing apparatus includes a washing tank, and further includes: The motion mechanism is located above the washing pool. A support component, which is rotatably mounted on a motion mechanism; The top plate is slidably mounted on the upper end of the support member; An annular sidewall, located between the support and the top plate, comprises multiple connecting plates that are sequentially hinged together by a pivot. The first electric push rod and the second electric telescopic rod are both installed on the support member, which are located on both sides of the annular side wall and are respectively connected to at least one connecting plate. By controlling the extension and retraction of the first electric push rod and the second electric telescopic rod, the annular sidewall is driven to switch between an expanded state for soaking and loading / unloading and a retracted state for rubbing and washing.

[0008] Furthermore, each of the connecting plates is provided with a first limiting surface and a second limiting surface for limiting the relative rotation angle of adjacent connecting plates.

[0009] Furthermore, elastic sheets are fixedly connected between adjacent connecting plates.

[0010] Furthermore, the telescopic end of the first electric push rod is connected to an electrically controlled slide rail seat, and the electrically controlled slide rail seat is slidably connected to a first plate, which is connected to at least one connecting plate.

[0011] Furthermore, some of the rotating shafts are equipped with torsion springs to keep the corresponding connecting plates in a predetermined posture when no external force is applied.

[0012] Furthermore, multiple connecting plates are arranged in groups, wherein the stiffness coefficient of the first torsion spring on the first connecting group is greater than the stiffness coefficient of the second torsion spring on the second connecting group; the first torsion spring causes the first connecting group to be in a straight line when no external force is applied, and the second torsion spring causes the corresponding connecting plate to have a tendency to rotate inward.

[0013] Furthermore, the motion mechanism includes an electrically controlled slide rail and a cylinder; the electrically controlled slide rail is mounted on a mounting frame, the cylinder is mounted on the electrically controlled slide rail, the telescopic end of the cylinder is connected to a U-shaped plate, and a motor for driving the support component to rotate is mounted on the U-shaped plate.

[0014] Furthermore, a second perforated plate is installed on the top plate.

[0015] Furthermore, the support member includes a support frame and a first perforated plate; the first perforated plate is fixedly installed at the bottom of the support frame.

[0016] Compared with the prior art, the present invention has the following beneficial effects: During soaking, the annular sidewall, the first perforated plate, and the second perforated plate form a receiving cavity, allowing water to flow freely while effectively blocking down and preventing down loss. When the annular sidewall is in the first closed state, it performs a track-like movement, thereby kneading the down.

[0017] After cleaning, the annular sidewall is moved to the side of the support frame and top plate. During the rising process, the grease, scum and other pollutants floating on the surface of the cleaning liquid are completely isolated and cannot come into contact with the down, thus fundamentally avoiding secondary pollution of the down when it comes out of the water.

[0018] By alternating between two states, the annular sidewalls vibrate, overcoming the adhesion of wet down and allowing the down to fall off smoothly.

[0019] By deforming the annular sidewall, multiple processes such as soaking, scrubbing, pollution prevention, and unloading are integrated into one, which not only improves the cleaning effect but also significantly improves production efficiency and product quality. Attached Figure Description

[0022] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0023] like Figures 1-10 As shown, the technical solution adopted by the present invention is as follows: A down processing and washing device includes a washing pool 1, a motion mechanism, a support member, a top plate 9, and an annular sidewall.

[0024] like Figure 1 As shown, the motion mechanism is positioned above the cleaning tank 1. The motion mechanism includes an electrically controlled slide rail 2 and a cylinder 3. The electrically controlled slide rail 2 is fixed above the cleaning tank 1 by a mounting bracket. The electrically controlled slide rail 2 is horizontally positioned. The cylinder body of the cylinder 3 is mounted on the slider of the electrically controlled slide rail 2. The telescopic end of the cylinder 3 is vertically downward and fixedly connected to a U-shaped plate 4. The opening of the U-shaped plate 4 faces downward, and a motor 5 is fixedly mounted on one side of the U-shaped plate 4.

[0025] The support component is rotatably mounted on the motion mechanism. Specifically, the support component includes a support frame 6 and a first perforated plate 7, with the support frame 6 rotatably connected between the two ends of the U-shaped plate 4. The output shaft of the motor 5 is fixedly connected to the support frame 6, and the motor 5 drives the support frame 6 to rotate. The first perforated plate 7 is fixedly mounted on the bottom of the support frame 6.

[0026] like Figure 2 As shown, the top plate 9 is slidably mounted on the upper end of the support member. Specifically, an electric slide rail 8 is fixedly mounted on the upper end of the support frame 6, and the top plate 9 is fixedly connected to the slider of the electric slide rail 8. Driven by the electric slide rail 8, the top plate 9 slides relative to the support frame 6. A second perforated plate 10 is mounted on the top plate 9.

[0027] An annular sidewall is disposed between the support frame 6 and the top plate 9. The annular sidewall includes multiple connecting plates 11, which are sequentially hinged together by a pivot 12. The lower end of the annular sidewall is in sliding contact with the support member, and the upper end is in sliding contact with the top plate 9. The support frame 6, the top plate 9, and the annular sidewall together form a receiving cavity for accommodating down.

[0028] like Figure 5 , Figure 6As shown, each connecting plate 11 is provided with a first limiting surface 13 and a second limiting surface 14 for limiting the relative rotation angle between two adjacent connecting plates 11. Specifically, each connecting plate 11 has a first limiting surface 13 on both sides of its outward-facing end, and a second limiting surface 14 on both sides of its inward-facing end. When two adjacent connecting plates 11 are on the same straight line, they abut against each other through the first limiting surface 13. The annular sidewall is generally rectangular, and the connecting plate 11 located at the corner abuts against the adjacent connecting plate 11 through the second limiting surface 14.

[0029] To achieve a rectangular overall shape for the annular sidewall, torsion springs are installed on some of the rotating shafts 12, and the torsion springs are fixedly connected between the corresponding two connecting plates 11.

[0030] Specifically, multiple connecting plates 11 are arranged in groups, including a first connecting group 11a and a second connecting group 11b. For example... Figure 7 As shown, there are two first connection groups 11a, which are symmetrically arranged. Each first connection group 11a includes multiple connection plates 11. There are two second connection groups 11b, which are symmetrically arranged. Each second connection group 11b includes one connection plate 11.

[0031] The torsion spring installed in the first connecting group 11a is a first torsion spring. Under the action of the first torsion spring, when no external force is applied, the first connecting group 11a forms a straight line. The torsion springs installed on both sides of the second connecting group 11b are second torsion springs. Under the action of the second torsion springs, the connecting plates 11 on both sides of the second connecting group 11b tend to converge inward. The stiffness coefficient of the first torsion spring is greater than that of the second torsion spring.

[0032] An elastic sheet 15 is fixedly connected between two adjacent connecting plates 11. The elastic sheet 15 is made of a wear-resistant and corrosion-resistant elastic material. Its material includes, but is not limited to, thermoplastic polyurethane, thermoplastic polyester elastomer, silicone rubber, and elastic fabrics made of nylon, polyester, and spandex blends or coatings, or laminated materials composed of TPU and the above-mentioned fabrics. The elastic sheet 15 is used to prevent down comforters from getting caught in the gaps between the connecting plates 11.

[0033] A first electric push rod 16 and a second electric telescopic rod 19 are installed on the support frame 6 to drive the deformation of the annular sidewall. The first electric push rod 16 and the second electric telescopic rod 19 drive the annular sidewall to switch between an expanded state for soaking and loading / unloading and a contracted state for rubbing.

[0034] The first electric push rod 16 and the second electric telescopic rod 19 are respectively disposed on both sides of the annular sidewall. The telescopic end of the first electric push rod 16 is fixedly connected to an electrically controlled slide rail seat 17, and a first plate 18 is slidably connected to the electrically controlled slide rail seat 17. The first plate 18 is fixedly connected to at least one connecting plate 11 on the annular sidewall. The telescopic end of the second electric telescopic rod 19 is fixedly connected to a second plate 20, and the second plate 20 is fixedly connected to at least one connecting plate 11 on the annular sidewall. In this embodiment, the connecting plate 11 in the middle of one first connecting group 11a is fixedly connected to the first plate 18, and the connecting plate 11 in the middle of the other first connecting group 11a is fixedly connected to the second plate 20.

[0035] Working principle: In the initial state, such as Figure 7 As shown, the annular sidewall is in the unfolded state. Under the action of the first torsion spring and the second torsion spring, the annular sidewall is square. The two first connecting groups 11a are located on the top and bottom edges of the square, respectively, and the two second connecting groups 11b are located in the middle of the left and right edges of the square, respectively. At this time, the first perforated plate 7, the second perforated plate 10, and the annular sidewall together form a receiving cavity.

[0036] At the start of operation, first activate the electric slide rail 8, which drives the top plate 9 and its second perforated plate 10 to slide along the support frame 6, opening the top of the receiving cavity. Place the down to be cleaned into the receiving cavity, and then reset the top plate 9 via the electric slide rail 8, resealing the receiving cavity.

[0037] Next, cylinder 3 is extended, causing support frame 6 to move downwards via U-shaped plate 4, so that the receiving cavity is completely immersed in the cleaning solution in cleaning tank 1. The cleaning solution enters the receiving cavity through first perforated plate 7 and second perforated plate 10, making full contact with the down and initiating the soaking process.

[0038] During the soaking process, the cylinder 3 can preferably be controlled to perform a small-amplitude reciprocating extension and retraction movement, so that the entire receiving cavity will shake slightly in the cleaning solution, thereby driving the internal cleaning solution to flow, promoting the full immersion of the down and the initial separation of dirt.

[0039] After soaking for the predetermined time, the down in the receiving cavity is rubbed and washed. The first electric push rod 16 and the second electric telescopic rod 19 extend synchronously, pushing the first plate 18 and the second plate 20 to move towards each other. Since the first plate 18 and the second plate 20 are fixedly connected to the connecting plates 11 in the middle of the two first connecting groups 11a, the two first connecting groups 11a move inward as a whole. As the distance between the two first connecting groups 11a decreases, the elastic force of the second torsion springs on the connecting plates 11 on both sides of the second connecting group 11b is released, causing the two second connecting groups 11b to move away from each other. Under the coordinated guiding and limiting action of the first limiting surface 13 and the second limiting surface 14, the connecting plates 11 on the left and right sides move upward and downward. With the movement of the first plate 18 and the second plate 20, the annular sidewall gradually changes from its initial square state to a long, narrow first converged state, as... Figure 8 As shown.

[0040] Subsequently, the electrically controlled slide rail seat 17 is activated, driving the first plate 18 to perform reciprocating linear motion. The first plate 18, through the connecting plate 11 fixed to it, transmits the reciprocating motion to the annular sidewall in its first retracted state, causing the annular sidewall in its first retracted state to perform continuous track-like reciprocating motion. During this process, the connecting plate 11 located at the upper part of the annular sidewall moves in the opposite direction to the connecting plate 11 at the lower part, rubbing and squeezing the down feathers between them to quickly remove dirt from the down. The dirt removed is discharged into the cleaning tank 1 along with the cleaning liquid through the first perforated plate 7 and the second perforated plate 10.

[0041] During the washing process, some connecting plates 11 rotate continuously via the rotating shaft 12, causing the two second limiting surfaces 14 between adjacent connecting plates 11 to open and close continuously. The elastic sheets 15 provided between adjacent connecting plates 11 effectively prevent down comforters from getting caught in the gaps between adjacent connecting plates 11, ensuring the smooth progress of the washing process. Furthermore, the elastic sheets 15 on the rectangular sides are in a stretched state, which can knead the down and ensure the washing effect.

[0042] After washing, turn off the electric sliding rail seat 17 to stop the track movement of the annular side wall.

[0043] Then, the first electric push rod 16 can be shortened and the second electric telescopic rod 19 can be extended, so that the annular sidewall returns to its initial unfolded state. The cylinder 3 drives the support frame 6 to move up and down reciprocally, which drives the cleaning fluid to flow, so that the dirt washed off the down is discharged through the first perforated plate 7 and the second perforated plate 10, and the down is rinsed.

[0044] Then, by extending the first electric push rod 16 and the second electric telescopic rod 19, the annular sidewall moves to the first retracted state, as shown below. Figure 8As shown, as the annular sidewall gradually contracts, the volume of the receiving cavity gradually decreases, thereby squeezing out the cleaning fluid inside the receiving cavity. Then, the first electric push rod 16 continues to extend, while the second electric telescopic rod 19 is controlled to retract. This causes the annular sidewall, in its first contracted state, to move towards one side of the support frame 6, carrying the down feathers. This causes the upper end of the annular sidewall to detach from the second perforated plate 10 and the lower end to detach from the first perforated plate 7, allowing the annular sidewall to fit tightly against the side of the support frame 6 and the edge of the top plate 9, forming a sealed space at the top, bottom, and sides. The position and state of the annular sidewall at this time are as follows... Figure 9 As shown.

[0045] Next, the control cylinder 3 contracts, causing the support frame 6 to rise smoothly and vertically, completely detaching the support frame 6 from the liquid surface of the cleaning tank 1. Because the down comforter is completely sealed, during the ascent, grease, scum, and other contaminants floating on the surface of the cleaning liquid are completely isolated and cannot come into contact with the down, thus fundamentally preventing the down from being secondary contaminated when it exits the water.

[0046] Then, the first electric push rod 16 is retracted and the second electric telescopic rod 19 is extended, restoring the annular sidewall to its initial unfolded state. At this time, the cleaning fluid remaining in the receiving cavity drains out through the first perforated plate 7 and flows back to the cleaning tank 1.

[0047] Then, the electrically controlled slide rail 2 is activated, causing the U-shaped plate 4 and support frame 6 to move horizontally above the preset collection box. Subsequently, the electrically controlled slide rail 8 is activated again to open the top plate 9. The motor 5 is started, driving the support frame 6 to rotate 90 degrees (or 180 degrees as needed), and the down feathers fall into the collection box under their own gravity.

[0048] Because wet down has strong adhesive properties, it is difficult for it to completely detach by gravity alone. Therefore, the first electric push rod 16 and the second electric telescopic rod 19 extend, causing the first plate 18 and the second plate 20 to move closer together, thus changing the annular sidewall towards a first contracted state. When the annular sidewall moves to such a position... Figure 8 After the first retracted state is shown, the first electric push rod 16 and the second electric telescopic rod 19 are shortened, causing the first plate 18 and the second plate 20 to move away from each other, thus gradually unfolding the annular sidewall. Then, the first electric push rod 16 and the second electric telescopic rod 19 are further shortened, causing the connecting plates 11 on the top and bottom edges of the rectangle to move to the left and right sides, gradually lengthening the left and right sides of the rectangle until the distance between the first plate 18 and the second plate 20 is at its maximum, as shown. Figure 10 As shown, the annular sidewall is in the second contracted state at this time.

[0049] Similarly, by controlling the alternating extension and retraction of the first electric push rod 16 and the second electric telescopic rod 19, the annular sidewall alternates between a first retracted state and a second retracted state, creating a shaking effect. The down adhering to the connecting plate 11, the elastic sheet 15, and the first perforated plate 7 is loosened and peeled off by the shaking, and falls into the collection box below under gravity, achieving efficient and thorough unloading.

[0050] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
