Description

Technical Field

[0001] This invention belongs to the technical field of down processing equipment, specifically relating to a down cluster and down fiber screening device for antibacterial down production and processing. Background Technology

[0002] In the production and processing of down products, the selection of down clusters and down fibers is a crucial step. Down clusters, as the main component of down, directly affect the warmth and appearance of down products due to their size, shape, and quality. Down fibers, on the other hand, are typically used as filling material, and their quality also influences the overall quality of the product.

[0003] Existing screening devices typically employ mechanical vibration or airflow separation, but these methods present several challenges in practical operation. First, mechanical vibration screening devices are prone to damaging the down clusters, affecting product quality. Second, while airflow separation devices can effectively separate down clusters and filaments, the separation effect is difficult to control precisely, and they are not effective at screening tiny filaments. Summary of the Invention

[0004] The purpose of this invention is to provide a down cluster and down fiber screening device for antibacterial down production and processing, so as to solve the problems mentioned in the background art.

[0005] The present invention achieves the above objectives through the following technical solutions:

[0006] This invention proposes a down cluster and down fiber screening device for antibacterial down production and processing, including a separation chamber, an airflow chamber and a side box symmetrically arranged on both sides of the separation chamber. The airflow chamber introduces horizontal airflow into the separation chamber through air holes, and the side box is used to receive the down fibers separated by the horizontal airflow.

[0007] The separation chamber is equipped with stirring blades that are driven to rotate by a rotating shaft, a screen one located at the bottom of the separation chamber, a screen two located on the side of the separation chamber opposite to the air hole, and a guide base located inside the separation chamber for conveying the fluff separated by screen two to screen one. The fluff enters screen two after passing through the guide base.

[0008] The aperture of the first screen is larger than that of the second screen.

[0009] Furthermore, the separation chamber is equipped with a drive wheel, which is connected to a driven wheel one via a belt one, and the driven wheel one is connected to a driven wheel two via a belt two.

[0010] The driven wheel is fixedly mounted on the end of the rotating shaft;

[0011] The second screen is installed at the connection between the separation chamber and the side box via a side frame. The side frame is provided with a gas chamber filled with gas. An elastic telescopic rod is provided between the side of the second screen and the gas chamber. A transmission slider is movably inserted into the gas chamber.

[0012] A conversion mechanism is provided at the center of the driven wheel 2. The conversion mechanism includes a transmission wheel coaxially arranged with the driven wheel 2. The outer ring of the transmission wheel is provided with a ring protrusion. When the driven wheel 2 rotates, it synchronously drives the transmission wheel to rotate. The ring protrusion periodically impacts the transmission slider, causing the screen 2 to vibrate periodically.

[0013] Furthermore, the guide base includes an inclined surface for receiving the separated fluff, a plurality of guide plates disposed on the inclined surface, and a transmission assembly for driving the guide plates to periodically rotate toward the side away from the screen. The end of the guide plate away from the screen is fixed to the inclined surface by a positioning shaft.

[0014] Furthermore, the transmission assembly includes a limiting channel disposed within the material guide base, an insertion block disposed within the limiting channel, an elastic element disposed within the limiting channel for resetting the insertion block, a pull rope disposed on one side of the insertion block, a winding roller disposed within the limiting channel for winding the pull rope, a guide wheel disposed within the limiting channel for guiding the pull rope, and a sliding plate disposed within the material guide base;

[0015] The guide plate has a slot on its side that is compatible with the plug-in block;

[0016] The pull rope passes over the take-up roller and the guide wheel and is connected to one end of the slide plate component. The other end of the slide plate component is hinged to a transmission rod. A connecting shaft is provided on the surface of the transmission wheel and at a location other than the wheel center. The end of the transmission rod away from the slide plate component is hinged to the connecting shaft.

[0017] Furthermore, the filter screen is curled around its perimeter, and a horizontal filtration surface is formed at the bottom of the filter screen. The angle formed by the horizontal filtration surface and the inclined surface of the feed guide base is less than 30 degrees.

[0018] The beneficial effects of this invention are as follows:

[0019] 1. The present invention compresses the gas in the air chamber by periodically impacting the transmission slider with the annular protrusion, thereby driving the filter screen to vibrate. Compared with the mechanical vibration in the prior art, the vibration amplitude in the present invention is smaller, and based on the presence of gas in the air chamber, the reciprocating vibration screening causes less damage to the down.

[0020] 2. This invention uses an active wheel to break up the fluff clusters and filaments, and simultaneously links the filter screen to vibrate periodically to achieve initial separation of the fluff clusters and filaments. Then, the conversion mechanism links the guide plate on the guide base to reciprocate and flip to further separate the unseparated fluff clusters and filaments. Attached Figure Description

[0029] The present application will now be described in further detail with reference to the accompanying drawings. It should be noted that the following specific embodiments are only used to further illustrate the present application and should not be construed as limiting the scope of protection of the present application. Those skilled in the art can make some non-essential improvements and adjustments to the present application based on the above application content.

[0030] Example 1

[0031] like Figure 1As shown, this embodiment proposes a down cluster and down filament screening device for antibacterial down production and processing, including a separation chamber 1, and an airflow chamber 2 and a side box 3 symmetrically arranged on both sides of the separation chamber 1. The airflow chamber 2 introduces horizontal airflow into the separation chamber 1 through the air hole 103 (a fan 21 is provided on the side of the airflow chamber 2 to generate airflow). The side box 3 is used to receive the down filaments separated by the horizontal airflow. The separation chamber 1 is equipped with a stirring blade driven to rotate by a rotating shaft 102, a screen 101 located at the bottom of the separation chamber 1, a screen 201 located on the side of the separation chamber 1 opposite to the air hole 103, and a guide base 104 located inside the separation chamber 1 for conveying the down clusters separated by the screen 201 to the screen 101. The down clusters enter the screen 201 after passing through the guide base 104. The aperture of the screen 101 is larger than that of the screen 201.

[0032] It should be noted that in this invention, both screen 101 and screen 301 are used to screen down and filaments. That is, the down will be separated and collected by the feed hopper 5 and feed hopper 6 at the bottom of the separation chamber 1, while the separated down will be collected on the plane of screen 101 and the down will be taken out by the feed port set at the rear of the separation chamber 1.

[0033] In this embodiment, by setting stirring blades driven by rotating shaft 102 in separation chamber 1, the fluff and filaments in separation chamber 1 can be initially dispersed to prevent them from sticking together. Then, the fluff is suspended and transported horizontally by horizontal airflow, which facilitates the first separation of fluff and fluff by screen 2 301. In addition, the aperture of screen 101 is larger than that of screen 2 301 in this invention. That is, the fluff that is not screened out by screen 2 301 in the first separation process (i.e., the separated fluff) enters screen 101 through the guide base 104.

[0034] Combination Figure 1 , 2 Preferably, the separation chamber 1 is equipped with a drive wheel 7 (which is electrically driven and not shown in the figure), the drive wheel 7 is connected to a driven wheel 8 via a belt 10, and the driven wheel 8 is connected to a driven wheel 9 via a belt 11; the driven wheel 8 is fixedly mounted on the end of the rotating shaft 102; the screen 301 is installed at the connection between the separation chamber 1 and the side box 3 via a side frame 31, and the side frame 31 is provided with a gas chamber 32 filled with gas. An elastic telescopic rod 33 is provided between the side of 301 and the air cavity 32, and a transmission slider 34 is movably inserted into the air cavity 32; a conversion mechanism 91 is provided at the center of the driven wheel 9, the conversion mechanism 91 includes a transmission wheel 911 coaxially arranged with the driven wheel 9, and an annular protrusion 913 is provided on the outer ring of the transmission wheel 911; when the driven wheel 9 rotates, it synchronously drives the transmission wheel 911 to rotate, and the annular protrusion 913 periodically impacts the transmission slider 34, causing the screen 301 to vibrate periodically.

[0035] In specific implementation, the ring protrusion 913 periodically impacts the transmission slider 34, and the slider 34 compresses the gas in the air chamber 32, thereby driving the screen 301 to vibrate periodically (in this embodiment, the side frame 31 can be set on the side of the screen 301, without hindering the normal screening process of the screen 301).

[0036] In this embodiment, the driving wheel 7 drives the driven wheel 8 to rotate, thereby driving the stirring blades. At the same time, the driven wheel 9 drives the transmission wheel 911 to rotate, thereby enabling the annular protrusion 913 to periodically impact the transmission slider 34, causing the screen 301 to vibrate periodically. That is, the present invention achieves synchronous driving of the stirring blades and the screen 301 in the separation chamber 1 and the side box 3, and the periodic vibration of the screen 301 assists in the initial separation of fluff and filaments.

[0037] Combination Figure 3 In this embodiment, the guide base 104 includes an inclined surface for receiving the separated fluff, a plurality of guide plates 1041 disposed on the inclined surface, and a transmission assembly for driving the guide plates 1041 to periodically rotate toward the side away from the screen 101. The end of the guide plate 1041 away from the screen 101 is fixed on the inclined surface by a positioning shaft.

[0038] Combination Figure 7 It is understood that in this embodiment, the guide plate 1041 can be driven by the transmission component to achieve periodic flipping, that is, the plate surface facing the lower end of the slope flips around the plate surface away from the lower end of the slope. In specific implementation, since there are several evenly distributed guide plates 1041 on the slope, the rapid periodic flipping of the guide plates 1041 helps to further separate the unseparated piles and filaments on the slope. Moreover, due to the specific flipping direction, the piles and the filaments attached to them can be quickly and slightly lifted, achieving a similar effect to vibration separation.

[0039] Preferably, the transmission assembly includes a limiting channel disposed within the guide base 104, an insertion block 1042 disposed within the limiting channel, an elastic member 1047 disposed within the limiting channel for resetting the insertion block 1042, a pull rope 1044 disposed on one side of the insertion block 1042, a take-up roller 1045 disposed within the limiting channel for winding the pull rope 1044, a guide wheel 1046 disposed within the limiting channel for guiding the pull rope 1044, and a guide wheel 1046 disposed within the limiting channel for guiding the pull rope 1044. The base 104 contains a sliding plate 1048; the guide plate 1041 has a slot 1043 on its side that is compatible with the plug block 1042; the pull rope 1044 passes around the take-up roller 1045 and the guide wheel 1046 and is connected to one end of the sliding plate 1048; the other end of the sliding plate 1048 is hinged to a transmission rod 92; a connecting shaft 912 is provided on the surface of the transmission wheel 911 at a location other than the wheel center; the end of the transmission rod 92 away from the sliding plate 1048 is hinged to the connecting shaft 912.

[0040] Combination Figure 1-6 In this embodiment, the drive wheel 7 can not only drive the stirring blades to rotate and the filter screen 301 to vibrate periodically, but also link the guide plate 1041 on the guide base 104 to rotate periodically. In this embodiment, the rotation is achieved by the transmission rod 92 driving the sliding plate 1048 to move periodically back and forth. The sliding plate 1048 drives the pull rope 1044 to rotate the winding roller 1045, so that the winding roller 1045 winds up the other end of the pull rope, pulling the plug block 1042 to move along the limiting channel. It first disengages from the plug slot 1043, and then, under the action of the elastic member 1047, the plug block 1042 hits the slot 1043, causing the guide plate 1041 on the inclined surface to jump slightly (forming a tendency to rotate), which helps to separate the filaments adhering to the fluff. After being screened by the filter screen 101, the fine separation of filaments of different sizes in the fluff is achieved.

[0041] Combination Figure 2 Preferably, the filter screen 101 is curled around its perimeter, and a horizontal filter surface is formed at the bottom of the filter screen 101. The angle formed by the horizontal filter surface and the inclined surface of the guide base 104 is less than 30 degrees, which increases the residence time of the fluff and filaments on the guide base 104. The fluff is separated by vibration through the guide plate 1041 which rotates back and forth with small amplitude.

[0042] According to an embodiment of the present invention, the present invention uses the drive wheel 7 to break up the fluff and filaments, and simultaneously links the filter screen 301 to vibrate periodically to achieve the initial separation of the fluff and filaments. Then, the conversion mechanism 91 links the guide plate 1041 on the guide base 104 to reciprocate and flip to separate the unseparated fluff and filaments again.

[0043] It will be apparent to those skilled in the art that the embodiments of the present invention are not limited to the details of the exemplary embodiments described above, and that the embodiments of the present invention can be implemented in other specific forms without departing from the spirit or essential characteristics of the embodiments of the present invention. Therefore, the embodiments should be considered exemplary and non-limiting in all respects, and the scope of the embodiments of the present invention is defined by the appended claims rather than the foregoing description.
