Description

Technical Field

[0001] This invention belongs to the field of down processing technology, specifically relating to a manual sorting device for grading down clusters and its operating method. Background Technology

[0002] On existing down processing lines, air sorting equipment can be used to sort down in multiple stages. However, small non-down particles, clumps, and substandard down fibers mixed in between cannot be removed by machine. Therefore, manual sorting is indispensable in the existing down processing flow.

[0003] The manual sorting of down requires two operators. One operator is responsible for initially shaking the piled down to ensure it is conveyed to the next operator's workbench in small, continuous batches. The next operator uses tweezers in one hand and the other to spread the down evenly on the sorting table before picking out impurities. During this process, the easy movement and tangling of down fibers increases the workload and reduces efficiency. In practice, operators can only grab a small amount of down at a time to quickly spread it out using their hands and tweezers to observe any impurities. Therefore, when processing large quantities of down continuously, operators need to frequently grab and spread the down. There is room for simplification and efficiency improvement in this process. To address this, this invention provides a manual sorting device and its operating method for down cluster grading. Summary of the Invention

[0004] The purpose of this invention is to provide a manual sorting device for grading down fluff and its operating method in order to solve the above-mentioned problems.

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

[0006] This invention provides a manual sorting device for grading down fluff, including a frame consisting of a support platform and a bracket located above the support platform, a transfer mechanism located on the support platform and a feed pipe connected to the transfer mechanism, a number of electrostatic adsorption conveying mechanisms arranged in a ring array on the outside of the transfer mechanism, a number of conveying rollers corresponding one-to-one with the electrostatic adsorption conveying mechanisms installed on the transfer mechanism, and a down recycling mechanism on the conveying route of the electrostatic adsorption conveying mechanism.

[0007] The electrostatic adsorption conveying mechanism includes two drive rollers, with a conveyor belt sleeved on the outside of the drive rollers. The electrostatic adsorption conveying mechanism also includes an electrostatic generating mechanism that keeps the conveyor belt continuously charged with static electricity.

[0008] The transfer mechanism is used to collect and disperse down feathers, the conveying roller is used to grab down feathers in the transfer mechanism, and the electrostatic adsorption conveying mechanism is used to adsorb down feathers on the conveying roller and transport the adsorbed down feathers to the manual cleaning area and the recycling area in sequence.

[0009] As a further optimization of the present invention, the transfer mechanism includes a housing with output ports corresponding to the conveying spikes. A rotating frame is provided at the center of the housing, and a number of elastic levers of different lengths are arranged in a circular array around the rotating frame. The elastic levers have an arc-shaped structure with the inner end on top and the outer end on the bottom. The outer end of the elastic lever extends downward and outward to the inner contour edge of the housing and is fixed to the housing. A number of vertical bars are arranged in a circular array on the rotating frame, and the inner ends of the elastic levers all extend to the intervals between the vertical bars.

[0010] As a further optimization of the present invention, the electrostatic adsorption conveying mechanism is inclined and the bases of the two drive rollers are respectively fixed on the support platform and the bracket. The electrostatic adsorption conveying mechanism also includes two adhesive tapes wrapped around the drive rollers. The conveyor belt is detachably connected to the drive rollers through the adhesive tapes. The electrostatic generating mechanism includes two friction plates located on the inner side of the conveyor belt and in contact with the conveyor belt. The friction plates are fixed on the base of the drive rollers by the mounting bracket.

[0011] As a further optimization of the present invention, the down recycling mechanism includes a cover sleeved on the outside of the feed pipe and a discharge pipe connected to the cover sleeve through a feeding fan. The outside of the cover sleeve is connected to a number of wind hoods that correspond one-to-one with the electrostatic adsorption conveying mechanism. The wind hoods are provided with toothed ribs whose ends are attached to the surface of the conveyor belt.

[0012] As a further optimization of the present invention, an impurity recovery mechanism is provided on the support platform. The impurity recovery mechanism includes a collection box provided on the support platform, and a discharge pipe is connected to the collection box through a feeding fan. Several suction heads corresponding to the electrostatic adsorption and conveying mechanism are connected to the outside of the collection box through a pipe. A tool rack for installing the suction heads is provided on the support platform.

[0013] This invention provides an operating method for a manual sorting device for grading down fluff, comprising the following steps:

[0014] S1. Connect the feed pipe to the down conveying pipe, and place or connect the corresponding down collecting device and impurity collecting device at the outlet of the discharge pipe and the impurity discharge pipe respectively.

[0015] S2. First, turn on the transfer mechanism, electrostatic adsorption conveying mechanism, conveying licker roller, down recovery mechanism and impurity recovery mechanism, and then start feeding down into the feed pipe.

[0016] S3. The operator is positioned outside each electrostatic adsorption conveying mechanism, holding tweezers in one hand and a suction head in the other. After the conveyor belt delivers the down into the operator's line of sight, the operator can use the tweezers to directly pick out the impurities on the conveyor belt. The qualified down will remain on the conveyor belt. The operator uses both hands to move the tweezers holding the impurities close to the suction port of the suction head, and then releases the tweezers to collect the impurities and quickly free up the tweezers, making it convenient for the operator to quickly pick out the continuously conveyed down.

[0017] S4. Qualified down feathers left on the conveyor belt will be sucked into the hood under the action of airflow when passing through the recycling area, and finally output through the discharge pipe. Impurities that are picked out will be sucked into the collection box through the pipe under the action of airflow, and finally output through the discharge pipe.

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

[0019] This invention incorporates a transfer mechanism along the down transport route to disperse the down. Through the combined action of a conveyor roller and an electrostatic adsorption conveyor, the scattered down is transferred and spread evenly onto a conveyor belt. Firstly, the spread-out down on the conveyor belt fully exposes impurities trapped within it. The continuous rotation of the conveyor belt ensures continuous down transport, replacing the existing manual process of grabbing and spreading the down. Operators only need to observe the down on the conveyor belt and remove impurities, significantly reducing manual labor and improving processing efficiency. Secondly, the conveyor belt, in conjunction with the electrostatic generator, utilizes electrostatic adsorption to attract the down, preventing it from flying around. After sorting, airflow easily removes the down from the conveyor belt, greatly enhancing operational convenience. Attached Figure Description

[0028] The present application will now be described in further detail. 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.

[0029] Example 1

[0030] like Figure 1-7 As shown, the manual sorting equipment for down feather grading in this embodiment includes a frame consisting of a support platform 1 and a bracket 7 located above the support platform 1. It also includes a transfer mechanism 2 on the support platform 1 and a feed pipe 4 connected to the transfer mechanism 2. Several electrostatic adsorption conveying mechanisms 5 arranged in a ring array are provided on the outside of the transfer mechanism 2. Several conveying spikes 3 corresponding one-to-one with the electrostatic adsorption conveying mechanisms 5 are installed on the transfer mechanism 2. The spikes of the conveying spikes 3 are made of stainless steel straight rods or conical spikes. The length of the spikes is 0.5-1.5cm. Shorter spikes can avoid grabbing too much down. The stainless steel straight rods or conical spikes are conducive to the down quickly leaving the conveying spikes 3 under the electrostatic adsorption. A down recycling mechanism is provided on the conveying route of the electrostatic adsorption conveying mechanism 5.

[0031] The electrostatic adsorption conveying mechanism 5 includes two drive rollers 501, and a conveyor belt 503 is sleeved on the outside of the drive rollers 501. The electrostatic adsorption conveying mechanism 5 also includes an electrostatic generating mechanism that keeps the conveyor belt 503 continuously charged with static electricity. The material of the conveyor belt 503 can be common materials that are prone to static electricity, including chemical fiber, pure cotton, polyester, acrylic fabric and silk, or commercially available electrostatic dust removal cloth, preferably dark-colored materials.

[0032] The transfer mechanism 2 is used to collect down and disperse it. The conveying roller 3 is used to grab the down in the transfer mechanism 2. The electrostatic adsorption conveying mechanism 5 is used to adsorb the down on the conveying roller 3 and transport the adsorbed down to the manual cleaning area and the recycling area in sequence.

[0033] The manual sorting equipment for grading down fluff includes the following steps:

[0034] S1. Connect the feed pipe 4 to the down conveying pipe, and place or connect the corresponding down collecting device at the outlet of the discharge pipe 9.

[0035] S2. First, turn on the transfer mechanism 2, electrostatic adsorption conveying mechanism 5, conveying roller 3, down recovery mechanism and impurity recovery mechanism, and then start feeding down into the feed pipe 4.

[0036] S3. The operator is located outside each electrostatic adsorption conveying mechanism 5. An impurity collection device needs to be equipped at the side of the operator. After the conveyor belt 503 delivers the down into the operator's line of sight, the operator can use tweezers to directly pick out the impurities (including non-down impurities, clumps, and unqualified down fibers) on the conveyor belt 503 and manually put them into the impurity collection device to free up the tweezers. Qualified down will remain on the conveyor belt 503. The operator only needs to observe the down continuously conveyed on the conveyor belt 503 and pick out the impurities, which greatly simplifies the operation process, improves the sorting efficiency, and reduces the burden of manual labor.

[0037] S4. Qualified down feathers left on the conveyor belt 503 will be sucked into the hood 8 by the airflow under the action of the air hood 6 when passing through the recycling area, and finally output from the equipment through the discharge pipe 9.

[0038] Preferably, the transfer mechanism 2 includes a housing 201, on which output ports corresponding to the conveying spiked rollers 3 are provided. A rotating frame 202 is provided at the center of the housing 201, and a number of elastic levers 204 of different lengths are arranged in a circular array around the rotating frame 202. The elastic levers 204 have an arc-shaped structure with the inner end on top and the outer end on the bottom. The outer end of the elastic lever 204 extends downward and outward to the inner contour edge of the housing 201 and is fixed to the housing 201. A number of vertical rods 203 are arranged in a circular array on the rotating frame 202, and the inner ends of the elastic levers 204 all extend to the intervals between the vertical rods 203.

[0039] After the down comforter is fed into the box 201, it will freely accumulate and spread inside the box 201. The gear set drive unit 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 all directions can disperse the down. The vibration range formed by the cooperation of the vertical rod 203 and the elastic lever 204 can cover any irregular cavity inside the box 201, so that the down inside the box 201 can remain in a loose state. During the rotation, the conveyor roller 3 can maintain the effect of continuously grabbing a small amount of down for transfer. The grabbed down can be scattered on the conveyor roller 3. After these down comforters are adsorbed onto the conveyor belt 503, they are also scattered on the surface of the conveyor belt 503, which is conducive to fully exposing impurities and making it convenient for operators to observe and pick them.

[0040] Preferably, the electrostatic adsorption conveying mechanism 5 is inclined and the bases of the two drive rollers 501 are respectively fixed on the support platform 1 and the bracket 7. The electrostatic adsorption conveying mechanism 5 also includes two adhesive tapes 502 wrapped around the drive rollers 501. The conveyor belt 503 is detachably connected to the drive 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 plates 504 are fixed on the base of the drive rollers 501 by the mounting bracket. The friction plates can be made of glass, rubber or a sheet covered with velvet. The specific material is used in combination with the material of the conveyor belt 503.

[0041] During the continuous rotation of the conveyor belt 503, its inner wall generates static electricity by rubbing against the surface of the friction plate 504 for a long time. The entire conveyor belt 503 is installed by bonding with the adhesive tape 502, which facilitates regular replacement.

[0042] Preferably, the down recycling mechanism includes a cover cylinder 8 sleeved on the outside of the feed pipe 4, and a discharge pipe 9 connected to the cover cylinder 8 via a feeding fan. Several air hoods 6 corresponding one-to-one with the electrostatic adsorption conveying mechanism 5 are connected to the outside of the cover cylinder 8. The air hood 6 is provided with teeth that are attached to the surface of the conveyor belt 503 at their ends. The teeth can scrape up the down adsorbed on the conveyor belt 503 to achieve a rapid recycling effect. Under the action of airflow, the down passes through the air hood 6, the cover cylinder 8 and the discharge pipe 9 in sequence and is output. The cleaned conveyor belt 503 continues to rotate and when it passes through the conveyor roller 3, it adsorbs the down to be sorted again, thereby achieving a continuous sorting effect.

[0043] Example 2

[0044] Based on Embodiment 1, an impurity recovery mechanism is provided on the support platform 1. The impurity recovery mechanism includes a collection box 13 provided on the support platform 1, and a discharge pipe 14 is connected to the collection box 13 through a feeding fan. A plurality of suction heads 11 corresponding to the electrostatic adsorption conveying mechanism 5 are connected to the outside of the collection box 13 through a pipe 12. A tool rack 10 for installing the suction heads 11 is provided on the support platform 1.

[0045] When picking out impurities, the operator can hold tweezers in one hand and suction head 11 in the other. After picking out the impurities, the operator can use both hands to bring the tweezers holding the impurities close to the suction port of suction head 11, and then release the tweezers to collect the impurities. This allows the tweezers to be quickly freed up, making it convenient for the operator to quickly pick out the continuously conveyed down. The picked-out impurities will be sucked into collection box 13 through pipe 12 under the action of airflow, and finally output from the equipment through impurity discharge pipe 14.

[0046] 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.
