Description

Technical Field

[0001] This invention relates to the field of fine sorting technology for agricultural products, specifically to a mechanism for preventing the lint from scattering. Background Technology

[0002] Down refers to the finest, shortest, softest, and most abundant hairs in a fur coat. These hairs make up approximately 95% to 98% of the total hair fiber and come in various shapes, such as curved, spiral, straight, and curly, giving the fur a fluffy and dense feel. Down forms an insulating layer within the fur coat, preventing air circulation and effectively reducing heat loss from the animal's body, thus providing excellent warmth.

[0003] After washing and grading by air sieving, the fluff yields primary fluff, which contains many dander, grease particles, and small hair stalks (hereinafter collectively referred to as 'fine impurities'). Due to their surface characteristics, these fine impurities adhere to the fluff and are difficult to remove by air sieving. To further improve the quality of the fluff, manual intervention is required, using a combination of sieving and manual sorting to remove these fine impurities.

[0004] The general procedure is as follows: A clump of lint is laid flat on a sieve basket, and the sieve is rotated back and forth to sift out skin flakes and grease particles. The lint is then turned over, and the sieve is rotated again, repeating this process until almost all the skin flakes and grease particles have been sieved out. However, the lint is very prone to scattering during this turning process, so it must be done very slowly, resulting in low sieving efficiency. Finally, workers pick out the lint from after the skin flakes and grease particles have been sieved out, using tweezers to remove the small hairs. This picking process also requires careful handling of the lint, otherwise it is easily flung away. Therefore, to improve sorting efficiency, it is necessary to increase the efficiency of turning and picking, and to prevent the lint from scattering for too long during this process.

[0005] Therefore, a lint-preventing mechanism is designed. This mechanism should be able to cooperate with manual operation to achieve semi-automatic operation of lint screening and manual selection, and prevent lint from being scattered for too long during the operation, thereby improving the efficiency of lint sorting. Summary of the Invention

[0006] The purpose of this invention is to provide a lint-preventing mechanism to solve the problems described in the background art.

[0007] The technical solution of this invention is implemented as follows:

[0008] A lint-preventing mechanism includes a first support and a mounting platform on the first support, as well as a controller and an electrostatic generator. A circular through-hole is formed on the upper surface of the mounting platform, and a horizontally arranged first annular frame is rotatably mounted within the through-hole. A screen is installed inside the first annular frame. A reciprocating drive mechanism is also provided on the mounting platform to drive the first annular frame to rotate back and forth. A transparent annular cylindrical cover is also provided on the upper surface of the first annular frame. An opening with a closable door is formed on the side wall of the annular cylindrical cover. A second annular frame slides horizontally up and down inside the annular cylindrical cover, and an electrostatic adsorption mesh is installed inside the second annular frame. The second ring frame is electrically connected to the electrostatic generator. A connecting frame is also fixed at the upper end of the second ring frame, and a support frame is also fixed at the upper end of the mounting platform. A lifting control component is fixed on the support frame. The lifting control component is driven by the connecting frame to drive the second ring frame to move up and down inside the ring column cover. A collection cover with an opening at the upper end is also fixed at the lower end of the mounting platform. The collection cover covers the bottom of the through hole. An opening is opened at the bottom of the collection cover. A ventilation mechanism is connected to the outside of the opening. An air inlet is opened on the side wall of the collection cover. An air supply mechanism is connected to the outside of the air inlet. The reciprocating drive mechanism, the electrostatic generator, the lifting control component, the air supply mechanism, and the exhaust mechanism are all electrically connected to the controller.

[0009] When using the above method, open the door and place the lint into the circular cylindrical cover. Start the electrostatic generator to attach static electricity to the electrostatic adsorption mesh. Then, start the reciprocating drive mechanism to rotate the first circular frame back and forth, causing reciprocating motion between the screen and the lint, thus sifting off dander and grease particles. After sifting for a period of time, when the workers can no longer clearly observe the sifting off of dander and grease particles, turn on the air supply mechanism.

[0010] The air supply mechanism pushes airflow into the collection hood. The airflow blows the lint on the screen through the screen. When the worker observes that all the lint has been blown onto the electrostatic adsorption net, the air supply mechanism is turned off and the exhaust mechanism is turned on. The exhaust mechanism draws air outward, causing the airflow inside the annular hood to flow downward through the electrostatic adsorption net. Because the overall volume of the lint is relatively large, it is easily carried away by the downward airflow and detached from the electrostatic adsorption net. The small lint sticks are smaller in volume and less affected by the airflow, so they can remain on the electrostatic adsorption net.

[0011] Once the worker observes that all the lint has been brought onto the screen, the exhaust system is turned off. The up-and-down movement of the lint effectively tumbles it, and during this tumbling, small lint strands are removed by an electrostatic adsorption screen. During the screening process, workers can use adhesive rollers and brushes to electrostatically adsorb and remove these small lint strands from the screen.

[0012] By incorporating a lifting control component, the second circular frame can move up and down, thereby driving the electrostatic adsorption net to move up and down. This allows workers to adjust the height of the electrostatic adsorption net during the lint blowing process, based on actual conditions (different grades of lint have different weights, and different effects of being blown away and drawn back by the wind). When lint is blown up, this prevents lint from failing to reach the electrostatic adsorption net or taking too long to do so, shortening the lint dispersion time and reducing waiting time. When lint falls, this prevents lint from failing to detach from the electrostatic adsorption net or taking too long to detach, shortening the time lint leaves the screen. Furthermore, the adjustable voltage function of the electrostatic generator allows for timely adjustment of the electrostatic voltage according to the actual adsorption situation, ensuring that the electrostatic adsorption net effectively adsorbs small lint sticks but not lint during ventilation.

[0013] After repeated operations, once the workers observe that the fine impurities have been completely removed, they can shut down all the equipment, open the door of the circular cylindrical cover, and remove all the lint.

[0014] This device can effectively achieve rapid tumbling of fluff within the circular cylindrical enclosure, and shorten the fluff dispersion time during the tumbling process, preventing excessive fluff dispersion time and improving the screening efficiency of the screen. At the same time, it can effectively remove small fluff stalks during the fluff tumbling process, changing the traditional manual sorting process and improving the overall efficiency of fluff purification operations.

[0015] A further technical solution is that the inner wall of the through hole protrudes inward to form a circular flange, the first circular frame is mounted on the flange, the outer wall of the first circular frame slides against the inner wall of the through hole, and the bottom of the first circular frame slides against the top of the flange.

[0016] A further technical solution is that the reciprocating drive mechanism includes an arc-shaped rack fixed to the upper end of the first circular frame, the arc-shaped rack being located outside the circular cylindrical cover. The reciprocating drive mechanism also includes a slide rail located on the upper surface of the mounting platform, and a straight rack slidably connected to the slide rail. The arc-shaped rack meshes with the straight rack. A telescopic cylinder is also fixed to the upper surface of the mounting platform, and the telescopic cylinder is connected to a five-position three-way solenoid valve. A connecting rod is also fixed to the straight rack. The telescopic rod of the telescopic cylinder drives the connecting rod, thereby driving the straight rack to reciprocate linearly in the slide rail. The five-position three-way solenoid valve is electrically connected to the controller.

[0017] When using the above scheme, the telescopic cylinder drives the connecting rod to move back and forth, the connecting rod drives the straight rack to move back and forth, the straight rack moves back and forth, thereby driving the circular rack to rotate back and forth, and the circular rack rotates back and forth, driving the first circular frame to rotate back and forth, thereby realizing the reciprocating sieving motion of the screen.

[0018] A further technical solution is that the support frame includes a vertical frame fixed to the upper end of the mounting platform, a horizontal frame is provided at the top of the vertical frame, the lifting control component is an electric push rod, the electric push rod is fixed to the bottom of the horizontal frame, the telescopic rod of the electric push rod extends downward and is fixedly connected to the connecting frame, and the electric push rod is electrically connected to the controller.

[0019] A further technical solution is that the bottom wall of the collection hood is also provided with multiple collection hoppers, and the bottom opening of the collection hopper is the passage. The exhaust mechanism includes a collection box located below the collection hood. The top of the collection box has multiple openings, and the number of openings on the top of the collection box is the same as the number of collection hoppers. The bottom of the collection hopper is also connected to the openings on the top of the collection box one by one through connecting pipes. Valves are provided in the connecting pipes. The side wall of the collection box is also provided with an exhaust port. An exhaust pipe is connected to the outside of the exhaust port. An exhaust fan is connected to the end of the exhaust pipe. The exhaust fan is electrically connected to the controller.

[0020] When using the above method, dander and grease particles fall into the collection hopper. When the exhaust fan starts, a negative pressure is generated in the collection box, which then draws air from the collection hood through the connecting pipe, simultaneously drawing the dander and grease particles from the collection hopper into the collection box for collection. Multiple collection hoppers and their bottom openings ensure that the drawn-in airflow acts evenly throughout the entire annular hood. By installing valves in the connecting pipes, the flow diameter can be changed, thus finely adjusting the suction level at the opening of each collection hopper, making the suction at each opening similar, and ensuring that the lint inside the annular hood receives uniform suction.

[0021] A further technical solution is that the air inlet is a long strip-shaped air inlet, and the air supply mechanism includes a conversion pipe located outside the collection hood. One end of the conversion pipe is connected to the air inlet, and the other end of the conversion pipe is connected to a blower. The blower is electrically connected to the controller. The airflow from the blower passes through the conversion pipe and the air inlet and is blown obliquely upward toward the screen. The air inlet of the blower can also be equipped with a blower cover that can be opened and closed.

[0022] When using the above scheme, the airflow from the blower is converted into a long strip shape through the conversion structure, resulting in a wider blowing range. When exhausting, the fan cover serves as the air inlet for the blower, thereby increasing the suction force of the exhaust fan within the collection hood.

[0023] A further technical solution is that there are two air inlets, which are respectively distributed on opposite side walls of the collection hood, and each air inlet is equipped with an air supply mechanism.

[0024] When using the above scheme, by setting two opposing air inlets, the distribution of the rising airflow can be made more uniform.

[0025] A further technical solution is that the connecting pipe includes an upper connecting pipe, a middle connecting pipe and a lower connecting pipe. The upper connecting pipe is connected to the opening at the bottom of the collecting hopper, the lower connecting pipe is connected to the opening at the top of the summing box, the middle connecting pipe is used to connect the upper connecting pipe and the lower connecting pipe, and the valve of the connecting pipe is located in the upper connecting pipe.

[0026] A further technical solution is that the side wall of the collection box is also provided with an opening, and the opening of the side wall of the collection box can be sealed with a door that can be opened and closed. The inside of the collection box is also provided with a detachable filter screen, which is located above the air extraction port.

[0027] When using the above solution, the filter screen also filters and collects skin flakes and grease particles, and the filter screen can be removed for cleaning and replacement by opening the collection box door.

[0028] A further technical solution is that a second support is provided at the bottom of the collection cover and the conversion pipe.

[0029] The beneficial effects of this invention are as follows:

[0030] 1. High-efficiency tumbling and screening: Through the reciprocating drive mechanism and screen, the lint, dander, and oil particles are effectively screened off. The rising and falling airflow inside the annular column cover, combined with the electrostatic adsorption net, effectively achieves rapid tumbling of the lint, reduces the time of lint dispersion, and prevents lint from being dispersed for a long time. At the same time, during the tumbling process, the electrostatic adsorption net effectively adsorbs small lint that is difficult to screen out by the screen.

[0031] 2. Electrostatic adsorption to remove small lint stems: Electrostatic adsorption nets are used to remove small lint stems from the fluff, changing the traditional manual sorting process and improving the overall efficiency of fluff purification.

[0032] 3. Adjustable Adsorption Effect: The electrostatic generator features adjustable voltage, allowing for timely adjustments based on actual adsorption conditions to ensure effective adsorption of small hairs without attracting lint. The lifting control unit allows the electrostatic adsorption net to be moved up and down to accommodate lint of varying weights, shortening lint dispersion time and reducing waiting time.

[0033] 4. Uniform air extraction and material collection: The design of multiple collection hoppers and hopper openings, combined with the valve adjustment in the connecting pipe, achieves uniform airflow distribution within the annular column hood, effectively collecting skin flakes and grease particles.

[0034] 5. Optimize airflow blowing and exhaust: The airflow blown out by the blower is transformed into a long strip shape through the conversion structure, expanding the blowing range; during exhaust, the design of the blower cover enhances the suction force inside the collection hood, and the opposing air inlets make the rising airflow distribution more uniform.
