Description

Technical Field

[0001] This invention relates to the field of wool processing equipment technology, specifically to a wool sorting device and its usage method. Background Technology

[0002] Wool fabrics are widely used in the clothing industry due to their excellent warmth retention and wearing comfort. In the wool fabric production process, sorting is a crucial step in wool processing. Its main purpose is to meticulously classify the acquired wool of various qualities and types, ensuring that wool of the same type and quality is separated, while also removing impurities and stains. This step is essential for the efficiency of subsequent processing and the quality of the final wool products.

[0003] Existing sorting steps include breaking down, removing impurities, and quality grading. The breaking down and removing impurities is crucial, as it forms the basis for quality grading. This is because the collected wool contains a large number of particulate impurities and tends to clump together; without sufficient breaking down, grading is difficult. Current wool processing sorting equipment performs breaking down and removing impurities separately, resulting in low processing efficiency. Furthermore, most equipment uses mechanical breaking down (e.g., agitators), which can easily damage the wool and reduce its quality. In addition, the particle size of impurities in wool varies greatly, and the wool itself is quite fine; therefore, conventional filtration methods are insufficient for efficiently separating wool from these particulate impurities. Summary of the Invention

[0004] The purpose of this invention is to provide a wool sorting device and its usage method, which solves the defects of existing wool sorting devices, such as low efficiency in breaking down and removing impurities, easy damage to wool, and difficulty in efficiently separating particulate impurities.

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

[0006] A wool sorting device includes a scattering and impurity removal box and a sorting and collection box. The scattering and impurity removal box is equipped with a vent plate that divides the interior of the scattering and impurity removal box into an upper cavity and a lower cavity. The upper cavity is equipped with a feed inlet, and the top of the upper cavity is connected to the sorting and collection box through a flow channel. The lower cavity is connected to an air conveying component.

[0007] The feed inlet is used to feed wool into the upper cavity, and the air conveying component is used to convey gas into the lower cavity. The gas passes through the air permeable plate and acts on the wool to break it up. The wool then rises with the airflow and enters the sorting and collection box through the flow channel. Particle impurities in the wool remain on the air permeable plate.

[0008] A further improvement is that a double-gate sealing feeding mechanism is provided at the feed inlet.

[0009] A further improvement is that the flow channel is composed of an ascending section, a horizontal section and a descending section that are sequentially connected, and a first exhaust plate is provided at the position where the descending section and the horizontal section are connected, directly facing the horizontal section.

[0010] A further improvement is that a blower and a second exhaust plate are respectively provided at opposite positions on the side wall of the sorting and collection box. The blower is used to generate horizontal wind that blows towards the second exhaust plate. The bottom end of the descending section is located on the horizontal wind path. Several collection chambers are arranged sequentially inside the sorting and collection box along the horizontal wind path.

[0011] A further improvement is that the upper cavity is integrally formed from a constant diameter section and a variable diameter section. The constant diameter section is cylindrical, and the variable diameter section is located above the constant diameter section. The radius of the variable diameter section first increases and then decreases from bottom to top.

[0012] A further improvement is that a guide rod is vertically installed in the upper cavity, and a movable disc matching the size of the equal-diameter section is slidably mounted on the guide rod. The movable disc is provided with several first one-way valves, and several second one-way valves are provided on the bottom side wall of the upper cavity. The upper cavity is also provided with a drive mechanism for driving the movable disc to reciprocate between the equal-diameter section and the variable-diameter section along the guide rod. When the movable disc moves downward in the equal-diameter section, the first one-way valves open and the second one-way valves close, and the movable disc presses down to gradually shrink the wool. When the movable disc moves upward in the equal-diameter section, the first one-way valves close and the second one-way valves open, and external gas is injected into the upper cavity through the second one-way valves to diffuse the wool.

[0013] A further improvement is that a support frame is provided inside the variable diameter section of the upper cavity, and the guide rod is installed in the middle position of the upper cavity through the support frame.

[0014] A further improvement is that the speed at which the drive mechanism drives the movable disc to move downward along the guide rod is less than the speed at which it moves upward along the guide rod.

[0015] A further improvement is that the drive mechanism includes a rack mounted on the support frame and parallel to the guide rod, an incomplete gear mounted on the movable disk, and an elastic element connecting the movable disk and the support frame. When the incomplete gear is driven to rotate, it meshes with or disengages from the rack. When the incomplete gear meshes with the rack, it rolls downward along the rack, thereby driving the movable disk to move downward along the guide rod. When the incomplete gear disengages from the rack, the elastic element pulls the movable disk upward along the guide rod.

[0016] The present invention also provides a method of using a wool sorting device, the steps of which include: feeding the wool to be sorted into the upper cavity through the feed inlet, activating the air conveying device to deliver gas into the lower cavity, the gas passing through the permeable plate and acting on the wool, breaking up the wool and rising with the airflow before entering the sorting collection box through the flow channel, while the particulate impurities in the wool remain on the permeable plate, thus completing the sorting.

[0017] The beneficial effects of this invention are as follows:

[0018] (1) The equipment integrates the functions of wool breaking, impurity removal and sorting, with high processing efficiency. It mainly utilizes air action, which helps to reduce damage to wool. Compared with the impurity removal of filter screen, the removal effect of impurities of different particle sizes is significantly improved. It can also further dry wool and improve the sorting effect.

[0019] (2) The device is also equipped with a movable disc in its upper cavity. The up and down movement of the movable disc can cause the wool quilt to shrink and spread repeatedly, so as to promote its disintegration and the removal of particulate impurities.

[0020] (3) The equipment can roughly classify wool of different fineness by using airflow, thereby reducing the workload of fine sorting in the later stage. Attached Figure Description

[0025] 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.

[0026] Combination Figure 1-3As shown, a wool sorting device includes a dispersing and impurity removal box 1 and a sorting and collection box 2. The dispersing and impurity removal box 1 is equipped with a permeable plate 3 inside. The permeable plate 3 allows gas to pass through while preventing wool, particulate impurities, etc. from passing through. The permeable plate 3 divides the interior of the dispersing and impurity removal box 1 into an upper cavity 4 and a lower cavity 5. The upper cavity 4 is equipped with a feed inlet 6. The top of the upper cavity 4 is connected to the sorting and collection box 2 through a flow channel 7. The lower cavity 5 is connected to an air supply component 8, such as an air pump.

[0027] The feed inlet 6 is used to feed wool to be sorted into the upper cavity 4. The collected wool raw materials are damp and clumped together, and contain a large number of particulate impurities. The air conveying component 8 is used to convey gas into the lower cavity 5, and to make the gas flow upward and evenly through the permeable plate 3 to act on the wool. The airflow disperses and dehumidifies the wool, making it lighter. The wool will rise with the airflow and then enter the sorting and collection box 2 through the flow channel 7, where it will be sorted and collected. The particulate impurities in the wool will remain on the permeable plate 3, thus completing the sorting process. In addition, the upper cavity 4 of the dispersion and impurity removal box 1 can be connected in sections and can be detached, which makes it easy to pour out the particulate impurities on the permeable plate 3 after sorting.

[0028] Preferably, the present invention has a double-gate sealing feeding mechanism at the feed inlet 6, that is, two sealing gates are set up, one above the other. During feeding, the upper gate is opened first and the lower gate is closed to feed the wool in. Then the upper gate is closed and the lower gate is opened, and the wool falls into the cavity. In this way, the cavity is completely sealed during the entire feeding process and will not affect the sorting process.

[0029] Preferably, in this invention, the flow channel 7 is composed of an ascending section, a horizontal section and a descending section connected in sequence, and a first exhaust plate 9 is provided at the position where the descending section and the horizontal section are connected, directly facing the horizontal section. In this way, most of the airflow discharged from the upper cavity 4 will be directly discharged to the outside through the first exhaust plate 9, while the wool will fall freely into the sorting and collection box 2.

[0030] Preferably, in this invention, a blower 10 and a second exhaust plate 11 are respectively provided at opposite positions on the side wall of the sorting and collection box 2. The blower 10 is used to generate a horizontal wind blowing towards the second exhaust plate 11, and the bottom end of the descending section is located on the horizontal wind path. A plurality of collection chambers 12 are arranged sequentially along the horizontal wind path inside the sorting and collection box 2. When wool falls into the sorting and collection box 2, the airflow blown by the blower 10 will give the wool a horizontal force, causing the wool to fall in a parabolic manner with an initial velocity of horizontal. The amount of displacement of the wool in the horizontal direction during the falling process is related to its fineness; the finer the wool, the greater the displacement, and the coarser the wool, the smaller the displacement. Thus, it can be sorted and collected by different collection chambers 12. Of course, this is only a coarse sorting, and subsequent manual fine sorting by technicians is still required.

[0031] Preferably, in this invention, the upper cavity 4 is integrally formed from a constant diameter section and a variable diameter section. The constant diameter section is cylindrical, and the variable diameter section is located above the constant diameter section. The radius of the variable diameter section first increases and then decreases from bottom to top. This increases the volume of the variable diameter section, making it easier for wool to be dispersed within the variable diameter section. At the same time, the gas flow rate is slowed down, which is beneficial for the removal of particulate impurities.

[0032] Preferably, in this invention, a guide rod 13 is vertically mounted in the middle position of the upper cavity 4 via a support frame 17. A movable disc 14 matching the size of the equal-diameter section is slidably mounted on the guide rod 13. The outer peripheral edge of the movable disc 14 is in a sealing sliding fit with the inner wall of the equal-diameter section. A plurality of first one-way valves 15 are provided on the movable disc 14, and a plurality of second one-way valves 16 are provided on the bottom side wall of the upper cavity 4. The upper cavity 4 is also provided with a drive mechanism for driving the movable disc 14 to reciprocate along the guide rod 13 between the equal-diameter section and the variable-diameter section. When the movable disc 14 moves downward within the equal diameter section, the first one-way valve 15 opens and the second one-way valve 16 closes. The movable disc 14 presses down, causing the wool to gradually shrink. When the movable disc 14 moves upward within the equal diameter section, the first one-way valve 15 closes and the second one-way valve 16 opens. External gas is quickly injected into the upper cavity 4 through the second one-way valve 16, causing the wool to diffuse. In this way, the wool can be repeatedly contracted and diffused during the impact and dispersion process of the bottom gas, which significantly improves the dispersion effect and facilitates the removal of particulate impurities.

[0033] It should be noted that in this invention, the speed at which the driving mechanism drives the movable disk 14 to move downward along the guide rod 13 is less than the speed at which it moves upward along the guide rod 13. This results in the movable disk 14 moving slowly downward and quickly upward, causing the volume of the space below the movable disk 14 to expand rapidly, generating negative pressure. This allows external airflow to be quickly injected into the upper cavity 4 through the second one-way valve 16, impacting the wool from multiple directions and ensuring that the wool is fully diffused.

[0034] In this invention, the driving mechanism can be a conventional driving component such as an electric telescopic rod or a telescopic cylinder, but it needs to be equipped with a special controller to control its extension and retraction, as well as the specific speed.

[0035] Here, the present invention provides a preferred drive mechanism that significantly simplifies control. It includes a rack 18 mounted on a support frame 17 and parallel to a guide rod 13, an incomplete gear 19 mounted on a movable disk 14, and an elastic element 20, such as a tension spring, connecting the movable disk 14 and the support frame 17. The incomplete gear 19 engages or disengages with the rack 18 when driven by a power source (e.g., a motor). When engaged, the incomplete gear 19 rolls downwards along the rack 18, causing the movable disk 14 to move downwards along the guide rod 13. When disengaged, the movable disk 14 is unrestricted and moves rapidly upwards along the guide rod 13 under the pull of the elastic element 20. This drive mechanism can be driven by a conventional motor, which only needs to rotate at a constant speed in one direction, requiring minimal control and meeting speed requirements.

[0036] The present invention also provides a method of using a wool sorting device, the steps of which include: feeding the wool to be sorted into the upper cavity 4 through the feed port 6, activating the air supply device 8 to supply gas into the lower cavity 5, the gas passing through the permeable plate 3 and acting on the wool, breaking up the wool and rising with the airflow before entering the sorting collection box 2 through the flow channel 7, while the particulate impurities in the wool remain on the permeable plate 3, thus completing the sorting.

[0037] The embodiments described above are merely examples of several implementations of the present invention, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the present invention. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and these modifications and improvements all fall within the scope of protection of the present invention.
