Description

Technical Field

[0001] The present invention relates to the technical field of wool processing equipment, and in particular to wool sorting equipment and a use method thereof. Background Art

[0002] Wool fabrics have excellent warmth retention and are comfortable to wear, and are widely used in the clothing field. In the wool fabric production process, the sorting process is an important part of the wool processing process. Its main purpose is to carefully classify the various qualities and types of wool purchased, ensure that wool of the same type and quality is separated, and remove impurities and stains. This step is crucial to the efficiency of the subsequent processing and the quality of the final wool products.

[0003] The existing sorting steps include breaking up, removing impurities and quality grading. Among them, the breaking up and removing impurities process is very important, which is the basis of quality grading, because the collected wool contains a large amount of particulate impurities and is easy to clump. If it is not fully broken up, it is difficult to grade. The existing wool processing sorting equipment performs the breaking up and removing impurities separately, with low processing efficiency, and most of them use mechanical breaking (such as stirring rods), which is easy to damage the wool and reduce the quality. In addition, the particle size of the particulate impurities in the wool varies, and the wool is relatively fine. Therefore, it is difficult to efficiently separate the wool from the particulate impurities through conventional filter separation measures. Summary of the invention

[0004] The object of the present invention is to provide a wool sorting device and a method for using the same, which solves the defects of the existing wool sorting device, such as low efficiency of breaking up and removing impurities, easy damage to wool, and difficulty in efficiently separating particulate impurities.

[0005] The present invention achieves the above-mentioned purpose through the following technical solutions:

[0006] A wool sorting device, comprising a scattering and impurity removal box and a classification and collection box, wherein a ventilation plate is provided inside the scattering and impurity removal box, and the ventilation plate divides the interior of the scattering and impurity removal box into an upper cavity and a lower cavity, wherein the upper cavity is provided with a feed inlet, and the top of the upper cavity is connected to the classification and collection box through a flow channel, and the lower cavity is connected with an air conveying member;

[0007] The feed port is used to feed wool into the upper cavity, and the gas conveying piece is used to convey gas into the lower cavity, and the gas passes through the air permeable plate to act on the wool, so as to break up the wool and enter the classification collection box through the flow channel after rising with the air flow, and the particulate 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 feeding port.

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

[0010] A further improvement is that a blowing member and a second exhaust plate are respectively provided at opposite positions on the side walls of the classification collection box, the blowing member is used to generate horizontal wind blowing towards the second exhaust plate, the bottom end of the descending section is located on the horizontal wind path, and a plurality of collection chambers are sequentially provided in the classification collection box along the direction of the horizontal wind path.

[0011] A further improvement is that the upper cavity is integrally formed by a constant diameter portion and a variable diameter portion, the constant diameter portion is cylindrical, the variable diameter portion is located above the constant diameter portion, and the radius of the variable diameter portion increases first 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 disk matching the size of the equal-diameter part is slidably provided on the guide rod. A plurality of first one-way valves are provided on the movable disk, and a plurality of second one-way valves are provided on the bottom side wall of the upper cavity. A driving mechanism for driving the movable disk to reciprocate between the equal-diameter part and the variable-diameter part along the guide rod is also provided in the upper cavity, and when the movable disk moves downward in the equal-diameter part, the first one-way valve opens and the second one-way valve closes, and the movable disk is pressed downward to gradually shrink the wool, and when the movable disk moves upward in the equal-diameter part, the first one-way valve closes and the second one-way valve opens, and the outside gas is poured into the upper cavity through the second one-way valve to diffuse the wool.

[0013] A further improvement is that a support frame is provided in the diameter-changing portion 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 driving mechanism drives the movable disk to move downward along the guide rod is lower than the speed at which the movable disk moves upward along the guide rod.

[0015] A further improvement is that the driving mechanism includes a rack provided on the support frame and parallel to the guide rod, an incomplete gear installed on the movable disk, and an elastic member connected between the movable disk and the support frame, wherein the incomplete gear engages with or disengages from the rack when driven by power, and when the incomplete gear engages with the rack, the incomplete gear rolls downward along the rack, thereby driving the movable disk to move downward along the guide rod, and when the incomplete gear disengages from the rack, the movable disk is pulled upward along the guide rod by the elastic member.

[0016] The present invention also provides a method for using a wool sorting device, the steps comprising: putting the wool to be sorted into the upper cavity from a feed port, starting the gas conveying component to convey gas into the lower cavity, the gas passing through the air permeable plate to act on the wool, breaking up the wool and rising with the air flow to enter a classification collection box through a flow channel, while the particulate impurities in the wool remain on the air permeable plate, and the sorting is completed.

[0017] The beneficial effects of the present invention are:

[0018] (1) The equipment integrates the functions of wool beating, impurity removal and classification, has high processing efficiency, and mainly utilizes the action of air, which helps to reduce damage to the wool.

DETAILED DESCRIPTION

[0025] The present application is further described in detail below in conjunction with the accompanying drawings. It is necessary to point out here that the following specific implementation methods are only used to further illustrate the present application and cannot be understood as limiting the scope of protection of the present application. Technical personnel in this field 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 comprises a scattering and impurity removal box 1 and a classification and collection box 2. A breathable plate 3 is arranged inside the scattering and impurity removal box 1. The breathable plate 3 can allow gas to pass through, but prevent wool, granular impurities, etc. from passing through. The breathable plate 3 divides the interior of the scattering and impurity removal box 1 into an upper cavity 4 and a lower cavity 5. The upper cavity 4 is provided with a feed inlet 6. The top of the upper cavity 4 is connected to the classification and collection box 2 through a flow channel 7. The lower cavity 5 is connected to a gas transmission member 8, such as an air pump, etc.;

[0027] Among them, the feed port 6 is used to put the wool to be sorted into the upper cavity 4, and the collected wool raw material is clumped due to moisture and mixed with a large amount of particulate impurities. The gas conveying part 8 is used to convey gas into the lower cavity 5, and make the gas evenly pass through the air permeable plate 3 upward to act on the wool. The wool is broken up and dehumidified by the air flow, and the wool becomes light and will rise with the air flow, and then enter the classification collection box 2 through the flow channel 7, and be classified and collected, while the particulate impurities in the wool remain on the air permeable plate 3, thereby completing the sorting process. In addition, the upper cavity 4 of the breaking and impurity removal box 1 can be connected in sections in a detachable manner, so that it is convenient to pour out the particulate impurities on the air permeable plate 3 after the sorting is completed.

[0028] Preferably, in the present invention, a double-gate sealed feeding mechanism is provided at the feeding port 6, that is, two upper and lower sealed gates are provided. When feeding, the upper gate is opened first, the lower gate is closed, and after the wool is fed in, 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, which will not affect the sorting process.

[0029] Preferably, the flow channel 7 in the present invention is composed of an ascending section, a horizontal section and a descending section which are connected in sequence, and a first exhaust plate 9 facing the horizontal section is provided at the junction of the descending section and the horizontal section, so that most of the airflow discharged from the upper cavity 4 will be directly discharged from the first exhaust plate 9 to the outside, and the wool will fall freely into the classification collection box 2.

[0030] Preferably, in the present invention, a blower 10 and a second exhaust plate 11 are respectively provided at opposite positions on the side wall of the classification collection box 2. The blower 10 is used to generate horizontal wind blowing toward the second exhaust plate 11. The bottom end of the descending section is located on the horizontal wind path. A plurality of collection chambers 12 are sequentially provided in the classification collection box 2 along the horizontal wind path. When the wool falls into the classification 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 being horizontal. The horizontal displacement of the wool 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, the wool can be classified and collected by different collection chambers 12. Of course, this is only a rough classification, and technicians will need to manually finely sort it later.

[0031] Preferably, the upper cavity 4 in the present invention is integrally formed by an equal diameter portion and a variable diameter portion, the equal diameter portion is cylindrical, the variable diameter portion is located above the equal diameter portion, and the radius of the variable diameter portion increases first and then decreases from bottom to top, so that the volume of the variable diameter portion is increased, the wool is easier to be dispersed in the variable diameter portion, and at the same time the gas flow rate is slowed down, which is conducive to the separation of particulate impurities.

[0032] Preferably, in the present invention, a guide rod 13 is vertically installed at the middle position in the upper cavity 4 through a support frame 17, and a movable disk 14 matching the size of the equal-diameter portion is slidably provided on the guide rod 13, and the outer peripheral edge of the movable disk 14 is sealed and slidably matched with the inner wall of the equal-diameter portion, and a plurality of first one-way valves 15 are provided on the movable disk 14, and a plurality of second one-way valves 16 are provided on the side wall of the bottom of the upper cavity 4. A driving mechanism for driving the movable disk 14 to reciprocate between the equal-diameter portion and the variable-diameter portion along the guide rod 13 is also provided in the upper cavity 4, and when When the movable disk 14 moves downward in the equal-diameter portion, the first one-way valve 15 opens and the second one-way valve 16 closes, and the movable disk 14 presses down to gradually shrink the wool. When the movable disk 14 moves upward in the equal-diameter portion, the first one-way valve 15 closes and the second one-way valve 16 opens, and the external gas quickly pours into the upper cavity 4 through the second one-way valve 16 to diffuse the wool. In this way, the wool can be repeatedly shrunk and diffused at the same time during the impact and dispersion process of the bottom gas, so that the dispersion effect is significantly improved and it is beneficial to the separation of particulate impurities.

[0033] It should be noted that the speed at which the above-mentioned driving mechanism drives the movable disk 14 to move downward along the guide rod 13 is lower than the speed at which it moves upward along the guide rod 13. In this way, the movable disk 14 moves slowly when moving downward and quickly when moving upward, so that the volume of the space below the movable disk 14 expands rapidly, generating negative pressure, allowing the external airflow to quickly flow into the upper cavity 4 through the second one-way valve 16, impacting the wool from multiple directions on all sides, and the wool is fully diffused.

[0034] The driving mechanism in the present invention can be a conventional driving member such as an electric telescopic rod, a telescopic cylinder, etc., but it needs to be equipped with a special controller to control the conversion of its telescopic and telescopic function, as well as the specific speed.

[0035] Here, the present invention provides a preferred driving mechanism, which is significantly simplified in control, and includes a rack 18 arranged on a support frame 17 and parallel to the guide rod 13, an incomplete gear 19 installed on the movable disk 14, and an elastic member 20 connected between the movable disk 14 and the support frame 17, such as a tension spring, the incomplete gear 19 is engaged with or disengaged from the rack 18 when the power drive (such as a motor) rotates, and when the incomplete gear 19 is engaged with the rack 18, the incomplete gear 19 will roll downward along the rack 18 when it rotates, thereby driving the movable disk 14 to move downward along the guide rod 13, and when the incomplete gear 19 is disengaged from the rack 18, the movable disk 14 is not restricted and will quickly move upward along the guide rod 13 under the pull of the elastic member 20. The driving mechanism can be driven by a conventional motor, and the motor only needs to rotate in one direction at a constant speed, without excessive control, and can meet the speed requirements.

[0036] The present invention also provides a method for using a wool sorting device, the steps comprising: feeding the wool to be sorted into the upper cavity 4 from the feed port 6, starting the gas conveying member 8, conveying gas into the lower cavity 5, the gas passing through the air permeable plate 3 to act on the wool, breaking up the wool and rising with the air flow to enter the classification collection box 2 through the flow channel 7, while the particulate impurities in the wool remain on the air permeable plate 3, and the sorting is completed.

[0037] The above-mentioned embodiments only express several implementation methods of the present invention, and the description thereof is relatively specific and detailed, but it cannot be understood as limiting the scope of the present invention. It should be pointed out that, for ordinary technicians in this field, several variations and improvements can be made without departing from the concept of the present invention, which all belong to the protection scope of the present invention.
