Description

Technical Field

[0001] This invention relates to the field of down filling material preparation technology, specifically a method and apparatus for preparing down filling material. Background Technology

[0002] Common down filling materials include duck down and duck down, which need to be prepared and processed by a preparation device before being filled into down jackets.

[0003] Most preparation devices typically include the following steps when preparing down filling: washing and disinfection, dehydration and drying, packaging and storage, etc. Among them, when dehydrating and drying down filling, some preparation devices allow down filling to enter a filter cylinder, and then the liquid in the down filling seeps out from the outer wall of the filter cylinder under the action of centrifugal force by rotating inside the filter cylinder.

[0004] While the above methods can achieve dehydration and drying, the down filling material adheres to the inner wall of the filter cylinder during rotation, causing blockage and affecting the dehydration quality of the down filling. This reduces the overall efficiency of down filling preparation. Therefore, we propose a method and apparatus for preparing down filling materials. Summary of the Invention

[0005] The purpose of this invention is to provide a method and apparatus for preparing down filling for down jackets, so as to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention provides the following technical solution: A down filling preparation apparatus includes a dehydration and drying device, a cleaning device, and a vacuum collection device connected to the input and output ends of the dehydration and drying device, respectively. The dehydration and drying device includes a housing, and a filter cylinder driven to rotate by a rotating device is rotatably disposed inside the housing. A feed pipe is provided at the top axis of the filter cylinder, penetrating the housing and communicating with the cleaning device. A sealing plate is rotatably disposed at the bottom of the inner cavity of the filter cylinder. A discharge part communicating with the vacuum collection device is provided on the sealing plate. An anti-clogging auxiliary mechanism is provided at the top of the sealing plate. The anti-clogging auxiliary mechanism includes a bearing shaft that is rotatably inserted into the sealing plate. A cleaning seat is sleeved on the outer wall of the bearing shaft above the sealing plate. A brush is provided on the outer side of the cleaning seat for contacting the inner wall of the filter cylinder.

[0007] A further improvement is that the discharge component includes a flow seat embedded in the top of the sealing disc and located inside the cleaning seat. The bottom of the flow seat passes through the axis of the sealing disc and extends into a hollow seat below the filter cylinder. The hollow seat is located on the inner wall of the bottom of the housing and is connected to the vacuum collection device through an adsorption tube.

[0008] A further improvement is that the upper end of the cleaning seat is connected to a connecting rod via a horizontal sliding member. The connecting rod is slidably connected to an annular guide rail on the inner wall of the top of the filter cylinder via a slider movably sleeved on the outer wall. The annular guide rail is provided with a pushing member for slidingly abutting the end of the connecting rod away from the horizontal sliding member. The pushing member is used to intermittently push the connecting rod to drive the cleaning seat to move along the bearing axis when the filter cylinder rotates. It also includes a connecting member for driving the cleaning seat to reset.

[0009] A further improvement is that an eccentric block is provided on the part of the bearing shaft located inside the cleaning seat, the eccentric block is used to drive the cleaning seat to move laterally, a driven gear is sleeved on the outer wall of the bearing shaft below the sealing plate, and a toothed ring is provided on the inner wall of the filter cylinder for meshing with the driven gear.

[0010] A further improvement is that the connecting member includes a bearing member sleeved on the outside of the bearing shaft. The inner wall of the bearing member is slidably connected to the vertical groove of the outer wall of the bearing shaft through a sliding block. The inner wall of the vertical groove is provided with an elastic connecting member two for driving the sliding block to reset. The two ends of the bearing member are respectively connected to the inner walls of the two sides of the cleaning seat through an elastic connecting member one.

[0011] A further improvement is that the inner side of the cleaning seat is provided with several sets of dispersion columns from top to bottom.

[0012] A further improvement is that the hollow seat is also connected to an air supply device through a vent pipe. Both the vent pipe and the adsorption pipe are equipped with control valves. A driven shaft is rotatably installed inside the hollow seat. A baffle for sealing the flow seat at one end of the hollow seat is provided on one side of the outer wall of the driven shaft. The driven shaft is connected to the bearing shaft in a driving connection.

[0013] A further improvement is that the actuating member includes an annular plate and a number of arc-shaped protrusions arranged in a circular array on one side of the annular plate.

[0014] A further improvement is that the inner circumferential wall of the housing is provided with several sets of heating elements.

[0015] A method for preparing down filling for a down jacket, utilizing the aforementioned preparation apparatus, includes the following steps: S1: After the down filling is cleaned by the cleaning equipment, it enters the filter cylinder through the feed pipe. Turn on the rotating equipment, and the rotating equipment drives the filter cylinder to rotate, so that the down filling is dehydrated and dried. When the filter cylinder is rotating, the brush parts rub against the inner wall of the filter cylinder to remove the down filling adhering to the inner wall of the filter cylinder. S2: After the down filling is dehydrated and dried in step S, the dehydrated and dried down filling is collected by a vacuum collection device.

[0016] Compared with the prior art, the beneficial effects of the present invention are: when the filter cylinder rotates, it rotates relative to the brush on the sealing plate. The brush can remove the down filling material attached to the inner wall of the filter cylinder by rubbing the inner wall of the filter cylinder, reducing the chance of filter cylinder clogging, ensuring the dehydration quality of the down filling material, and also improving the overall efficiency of the down filling material preparation work.

[0018] 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.

[0019] Example 1 Please see the appendix Figure 1 - Appendix Figure 3 A down filling preparation apparatus includes a dehydration and drying device 1, a cleaning device 2 and a vacuum collection device 3 respectively connected to the input and output ends of the dehydration and drying device 1; The above-mentioned dehydration, washing and vacuum collection are routine steps in the preparation of down fillings in existing down jackets, and will not be described in detail here. The washing equipment 2 is, for example, a washing machine, and the vacuum collection equipment 3 includes, for example, a collection shell and a vacuum device. The dehydration and drying equipment 1 includes a housing 4, and the inner circumference of the housing 4 is provided with several sets of heating elements 27, such as electric heating rods. The housing 4 is rotatably provided with a filter cylinder 6 driven to rotate by a rotating device 7. Specifically, the rotating device 7 includes a motor located at the top of the housing 4 and a gear set (two sets of meshing gears) that drive the output end of the motor and the filter cylinder 6. With this arrangement, the down filling after washing is dehydrated and dried under the centrifugal action of the filter cylinder 6. The filter cylinder 6 has a feed pipe 5 that passes through the housing 4 and is connected to the cleaning equipment 2 at the top axis. Specifically, the feed pipe 5 is fixedly connected to the housing 4, and a bearing is provided at the connection between the feed pipe 5 and the filter cylinder 6 so that the feed pipe 5 will not be affected by the rotation of the filter cylinder 6. The bottom of the inner cavity of the filter cylinder 6 is provided with a sealing plate 8 that rotates through a bearing. The sealing plate 8 is provided with a discharge part that is connected to the vacuum collection device 3. The top of the sealing plate 8 is provided with an anti-clogging auxiliary mechanism to prevent the down filling in the filter cylinder 6 from clogging the filter cylinder 6 and affecting the dehydration quality. The anti-blocking auxiliary mechanism in this device preferably uses two sets, symmetrically arranged on both sides of the sealing plate 8; The anti-clogging auxiliary mechanism includes a bearing shaft 9 that is rotatably inserted into the sealing plate 8. A bearing is provided at the connection between the bearing shaft 9 and the sealing plate 8. Its bottom end is rotatably connected to the bottom inner wall of the housing 4, so that the bearing shaft 9 will not rotate with the filter cylinder 6. The outer wall of the bearing shaft 9 above the sealing plate 8 is fitted with a cleaning seat 11. The outer side of the cleaning seat 11 is provided with a brush 12 for contacting the inner wall of the filter cylinder 6. When the filter cylinder 6 rotates, its inner wall rubs against the brush 12, so that the filter cylinder 6 will not clog the down filling and ensure the dehydration quality.

[0020] To prevent down from entering the cleaning seat 11, an elastic rubber sealing material can be installed at the connection between the cleaning seat 11 and the bearing shaft 9.

[0021] Please see the appendix Figure 4 Preferably, the discharge component in this embodiment includes a flow seat 22 embedded in the top of the sealing plate 8 and located inside the cleaning seat 11. The bottom of the flow seat 22 passes through the axis of the sealing plate 8 and extends into the hollow seat 23 below the filter cylinder 6. The hollow seat 23 is located on the bottom inner wall of the housing 4. The hollow seat 23 is connected to the vacuum collection device 3 through the adsorption tube 26. After the down filling is dehydrated and dried, the vacuum collection device 3 generates a vacuum adsorption force to extract the down filling in the filter cylinder 6. The down filling in the vacuum collection device 3 can be manually filled or otherwise prepared.

[0022] Please see the appendix Figure 5 Preferably, in this embodiment, the upper end of the cleaning seat 11 is connected to a connecting rod 18 via a horizontal sliding member 16. The horizontal sliding member 16 includes, for example, a horizontally arranged I-shaped rod and protrusions respectively provided at both ends of the top of the cleaning seat 11 and sleeved on the outer wall of the I-shaped rod. The horizontal sliding member 16 restricts the horizontal movement of the cleaning seat 11 and prevents it from rotating. The connecting rod 18 is slidably connected to the annular guide rail 17 on the top inner wall of the filter cylinder 6 via a slider that is movably sleeved on the outer wall. The annular guide rail 17 is coaxial with the filter cylinder 6. When the filter cylinder 6 rotates, it drives the annular guide rail 17, and then the annular guide rail 17 rotates relative to the connecting rod 18. The annular guide rail 17 is provided with a pusher 19 for sliding abutting the end of the connecting rod 18 away from the horizontal sliding member 16. The pusher 19 is used to intermittently push the connecting rod 18 to drive the cleaning seat 11 to move along the axis of the bearing shaft 9 when the filter cylinder 6 rotates. It also includes a connecting member for driving the cleaning seat 11 to reset. For example, please see the appendix. Figure 6 The actuating member 19 includes an annular plate 191 and several sets of arc-shaped protrusions 192 arranged in an annular array on one side of the annular plate 191. The annular plate 191 rotates with the annular guide rail 17, and then intermittently actuates the connecting rod 18 through the arc-shaped protrusions 192, so that the connecting rod 18 drives the horizontal sliding member 16 relative to the slider. The horizontal sliding member 16 drives the cleaning seat 11 to move along the axis of the bearing shaft 9. With this arrangement, the treatment effect of the brush member 12 on the down filling material attached to the inner wall of the filter cylinder 6 can be effectively improved.

[0023] Preferably, in this embodiment, the bearing shaft 9 is provided with an eccentric block 20 located eccentrically inside the cleaning seat 11. The eccentric block 20 is used to drive the cleaning seat 11 to move laterally. The outer wall of the bearing shaft 9 is fitted with a driven gear 24 below the sealing plate 8. The inner wall of the filter cylinder 6 is provided with a toothed ring 10 for meshing with the driven gear 24. When the filter cylinder 6 rotates, its toothed ring 10 rotates relative to the driven gear 24, thereby causing the driven gear 24 to drive the bearing shaft 9 to rotate. The bearing shaft 9 drives the eccentric block 20 to reciprocate in contact with the inner wall of the cleaning seat 11, causing the cleaning seat 11 to move laterally and generating a lateral vibration force. This not only improves the treatment effect of the brush 12 on the down filling material attached to the inner wall of the filter cylinder 6, but also makes it less likely for the down filling material to remain or adhere to the brush 12 and the cleaning seat 11.

[0024] Preferably, the connector in this embodiment includes a bearing 13 sleeved on the outside of the bearing shaft 9. The inner wall of the bearing 13 is slidably connected to the vertical groove of the outer wall of the bearing shaft 9 through a sliding block. The rotation of the bearing shaft 9 drives the sliding block, which causes the inner ring of the bearing 13 to rotate relative to its outer ring. The inner wall of the vertical groove is provided with an elastic connector 2 15 for driving the sliding block to reset. The two ends of the bearing 13 are respectively connected to the inner walls of the two sides of the cleaning seat 11 through an elastic connector 14. Both the elastic connector 2 15 and the elastic connector 14 are springs. The elastic connector 2 15 is used to drive the cleaning seat 11 to move upward, and the elastic connector 14 is used to drive the cleaning seat 11 to move horizontally and reset.

[0025] Preferably, the inner side of the cleaning seat 11 in this embodiment is provided with several sets of dispersing columns 21 from top to bottom. As the cleaning seat 11 moves up and down, the dispersing columns 21 can disperse the dehydrated down filling. The dispersing columns 21 include, for example, a horizontal main rod and support rods evenly arranged on the outer wall of the main rod. At the same time, the dispersing columns 21 can vibrate with the cleaning seat 11, which also effectively prevents down filling from remaining or adhering to its outer wall.

[0026] Preferably, the hollow seat 23 in this embodiment is also connected to an air supply device via a vent pipe 25, such as an air supply pump. Both the vent pipe 25 and the adsorption pipe 26 are equipped with control valves. A driven shaft 28 is rotatably provided inside the hollow seat 23. A baffle 29 for sealing the flow seat 22 at one end of the hollow seat 23 is provided on one side of the outer wall of the driven shaft 28. The driven shaft 28 is drivenly connected to the bearing shaft 9, for example, the driven shaft 28 and the bearing shaft 9 are drivenly connected via a sprocket drive assembly (including sprockets and chains). After dehydration and drying for a period of time, the moisture content in the down filling decreases and the weight of the down filling decreases. By opening the control valve in the vent pipe 25 and closing the control valve in the adsorption pipe 26, gas can be intermittently sprayed from the flow seat 22 into the filter cylinder 6, causing the down filling in the filter cylinder 6 to move upward. When the baffle 29 blocks the flow seat 22 at one end of the hollow seat 23, no gas is sprayed from the flow seat 22, and some of the down filling moves downward under its own weight. In this way, the down filling can move up and down in the filter cylinder 6 under the influence of gas and its own weight, colliding with the dispersion column 21, making it less likely for the down filling to clump together.

[0027] A method for preparing down filling for a down jacket, utilizing the preparation apparatus described above, includes the following steps: S1: After being cleaned by the cleaning equipment 2, the down filling enters the filter cylinder 6 through the feed pipe 5. The rotating equipment 7 is turned on, and the rotating equipment 7 drives the filter cylinder 6 to rotate, so that the down filling is dehydrated and dried. When the filter cylinder 6 is rotating, the brush 12 rubs the inner wall of the filter cylinder 6 to remove the down filling adhering to the inner wall of the filter cylinder 6. S2: After the down filling is dehydrated and dried in step S1, the dehydrated and dried down filling is collected by vacuum collection device 3.

[0028] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
