Description

Technical Field

[0001] The invention belongs to the technical field of down processing, and in particular relates to a manual sorting device for down cluster grading and an operating method thereof. Background Art

[0002] In the existing down processing lines, wind sorting equipment can be used to perform multi-stage sorting of down. However, impurities such as tiny non-down objects, clumps, and unqualified down fibers mixed between the down fibers cannot be removed by machines. Therefore, manual sorting steps are indispensable in the existing down processing flow.

[0003] The processing steps of manually sorting down require the cooperation of two operators. One operator is responsible for initially shaking out the accumulated down so that the down can be transported to the workbench of the next operator in a small amount and continuously. The next operator holds tweezers in one hand and cooperates with tweezers in the other hand to scatter the down. The impurities therein should be picked out after the down is completely spread out on the picking table. In this process, the problems of the down silk flying easily and being entangled easily will increase the workload of manual sorting and lead to low work efficiency. In actual operation, the operator can only grab a small amount of down each time to ensure that the down can be quickly spread out by the cooperation of hands and tweezers so as to observe the impurities mixed therein. Therefore, when continuously processing a large amount of down, the operator needs to grab the down and flatten the down at a high frequency. There is room for simplifying the operation and improving the efficiency in this process. In this regard, the present invention provides a manual sorting device for down flower grading and an operating method thereof. Summary of the invention

[0011] As a further optimization scheme of the present invention, the down recovery mechanism includes a cover cylinder which is sleeved on the outside of the feed pipe and the cover cylinder is connected to a discharge pipe through a feeding fan. The outside of the cover cylinder is connected to a plurality of wind hoods which correspond one by one to the electrostatic adsorption transmission mechanism.

DETAILED DESCRIPTION

[0028] The present application is described in further detail below. It is necessary to point out 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. Technicians in this field can make some non-essential improvements and adjustments to the present application based on the above application content.

[0029] Example 1

[0030] like Figure 1-7 As shown, the manual sorting equipment for down bud grading of this embodiment includes a frame consisting of a support platform 1 and a bracket 7 located above the support platform 1, and also includes a transfer mechanism 2 arranged on the support platform 1 and a feed pipe 4 connected to the transfer mechanism 2. A plurality of electrostatic adsorption conveying mechanisms 5 distributed in a ring array are arranged on the outer side of the transfer mechanism 2. A plurality of conveying licker-in rollers 3 corresponding to the electrostatic adsorption conveying mechanisms 5 are installed on the transfer mechanism 2. The thorns of the conveying licker-in roller 3 adopt a straight rod or cone thorn structure made of stainless steel. The length of the thorns is 0.5-1.5 cm. Shorter thorns can avoid excessive down being caught. The straight rod or cone thorn made of stainless steel is conducive to the down quickly detaching from the conveying licker-in roller 3 under the action of electrostatic adsorption. A down recovery mechanism is provided on the conveying route of the electrostatic adsorption conveying mechanism 5.

[0031] The electrostatic adsorption transmission mechanism 5 includes two driving rollers 501, and a conveyor belt 503 is provided on the outer side of the driving roller 501. The electrostatic adsorption transmission mechanism 5 also includes an electrostatic generating mechanism for continuously causing the conveyor belt 503 to be charged with static electricity. The material of the conveyor belt 503 can be selected from common fabrics that are prone to static electricity, including chemical fiber, pure cotton, polyester, acrylic fabrics and silk, or electrostatic dust-removing cloth on the market, preferably dark-colored material.

[0032] The transfer mechanism 2 is used to receive and disperse the down, the transfer roller 3 is used to grab the down in the transfer mechanism 2, and the electrostatic adsorption transfer mechanism 5 is used to adsorb the down on the transfer roller 3 and transport the adsorbed down to the manual impurity removal area and the recovery area in turn.

[0033] The manual sorting equipment for down grading comprises the following operating steps:

[0034] S1. Connect the feed pipe 4 to the down delivery pipeline, and place or connect the corresponding down collection piece at the outlet of the discharge pipe 9;

[0035] S2, first start the transfer mechanism 2, the electrostatic adsorption transmission mechanism 5, the transmission licker-in roller 3, the down recovery mechanism and the impurity recovery mechanism, and then start to input down into the feed pipe 4;

[0036] S3, the operator is located outside each electrostatic adsorption conveying mechanism 5, and the operator needs to be equipped with a foreign matter collector on his side. When the conveyor belt 503 conveys the down to the operator's sight, the operator can directly pick out the foreign matter (including non-down foreign matter, clumps, and unqualified down fibers, etc.) on the conveyor belt 503 with tweezers and then manually put them into the foreign matter collector to free the tweezers, and the qualified down will remain on the conveyor belt 503. The operator only needs to observe the continuously conveyed down on the conveyor belt 503 and pick out the foreign matter, which greatly simplifies the operation process, improves the sorting efficiency, and reduces the burden of manual labor;

[0037] S4. The qualified down remaining on the conveyor belt 503 will be sucked into the hood tube 8 through the wind hood 6 under the action of the airflow when passing through the recovery area, and finally output from the device through the discharge pipe 9.

[0038] Preferably, the transfer mechanism 2 includes a box body 201, the box body 201 is provided with output ports corresponding to the conveying licker-in rollers 3 one by one, a rotating frame 202 is provided at the center of the box body 201, and a plurality of elastic levers 204 distributed in a circular array and of different lengths are provided around the rotating frame 202, the elastic levers 204 are in an arc-shaped structure with the inner end at the top and the outer end at the bottom, the outer end of the elastic lever 204 extends downward and outward to the inner contour edge position of the box body 201 and is fixed to the box body 201, and a plurality of vertical rods 203 distributed in a circular array are provided on the rotating frame 202, and the inner ends of the elastic levers 204 extend to the intervals between the vertical rods 203;

[0039] After the down is input into the box 201, it will be freely accumulated and spread in the box 201. The gear group driving member arranged at the bottom of the box 201 can drive the rotating frame 202 to rotate continuously. During the continuous rotation of the rotating frame 202, the vertical rod 203 will intermittently collide with the inner end of the elastic lever 204, thereby causing the elastic lever 204 to vibrate as a whole. The continuous vibration of the elastic lever 204 in various directions can play the effect of breaking up the down, and the vibration range formed by the cooperation of the vertical rod 203 and the elastic lever 204 can cover any irregular inner cavity of the box 201, so that the down in the box 201 can be kept in a loose state. The conveying licker-in roller 3 can maintain the transfer effect of continuously grabbing a small amount of down during the rotation process, and the grabbed down can be scattered and distributed on the conveying licker-in roller 3. After these down are adsorbed on the conveyor belt 503, they are also scattered and distributed on the surface of the conveyor belt 503, which is conducive to fully exposing impurities and convenient for operators to observe and select.

[0040] Preferably, the electrostatic adsorption transmission mechanism 5 is inclined and the bases of the two driving rollers 501 are fixed on the support platform 1 and the bracket 7 respectively. The electrostatic adsorption transmission mechanism 5 also includes two adhesive tapes 502 wound around the driving rollers 501. The conveyor belt 503 is detachably connected to the driving rollers 501 through the adhesive tapes 502. The electrostatic generating mechanism includes two friction plates 504 located on the inner side of the conveyor belt 503 and in contact with the conveyor belt 503. The friction plate 504 is fixed on the base of the driving roller 501 through a mounting frame. The friction plate can be made of a glass plate, a rubber plate or a plate wrapped with flannel. The specific material is used in combination according to the material of the conveyor belt 503.

[0041] During the continuous rotation of the conveyor belt 503, its inner wall rubs against the surface of the friction plate 504 for a long time to generate static electricity, and the conveyor belt 503 is installed as a whole by bonding with the adhesive tape 502, which is convenient for regular replacement.

[0042] Preferably, the down recovery mechanism includes a hood tube 8 sleeved on the outside of the feed pipe 4 and the hood tube 8 is connected to a discharge pipe 9 through a feeding fan. The outside of the hood tube 8 is connected to a plurality of wind hoods 6 corresponding to the electrostatic adsorption transmission mechanism 5 one by one. The wind hood 6 is provided with a row of teeth whose ends are in contact with the surface of the conveyor belt 503. The row of teeth can scrape up the down adsorbed on the conveyor belt 503, thereby achieving a rapid recovery effect. Under the action of airflow, the down is output through the wind hood 6, the hood tube 8 and the discharge pipe 9 in turn. The cleaned conveyor belt 503 continues to rotate, and when passing through the conveying licker-in roller 3, it adsorbs the down to be sorted again, thereby achieving a continuous sorting effect.

[0043] Example 2

[0044] On the basis of Example 1, an impurity recovery mechanism is arranged on the support table 1, and the impurity recovery mechanism includes a collecting box 13 arranged on the support table 1, and the collecting box 13 is connected to a discharge pipe 14 through a feeding fan, and the outer side of the collecting box 13 is connected to a plurality of suction heads 11 corresponding to the electrostatic adsorption transmission mechanism 5 one by one through a connecting pipe 12, and a tool rack 10 for installing the suction head 11 is provided on the support table 1.

[0045] When picking out impurities, the operator can hold tweezers in one hand and the suction head 11 in the other hand. After picking out the impurities, the operator uses both hands to make the tweezers holding the impurities close to the suction port of the suction head 11, and then releases the tweezers to collect the impurities. The tweezers can be quickly emptied, which is convenient for the operator to quickly pick the continuously transported down. The picked impurities will be sucked into the collection box 13 through the connecting pipe 12 under the action of the airflow, and finally output from the device through the impurity discharge pipe 14.

[0046] 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.
