Description

Technical Field

[0001] This invention relates to the field of dust removal equipment technology, specifically an automatic dust removal device applied to a yarn toy production line. Background Technology

[0002] Plush toys and yarn toys need to be dusted after production. Plush toys and yarn toys have a lot of fluff on their surface, so they need to be dusted by special dust removal equipment.

[0003] To facilitate dust removal from yarn or plush toys, existing technologies have made numerous improvements to dust removal devices. For example, patent publication number CN220590980U discloses a dust removal device for plush toy production, including a main body, vacuum cleaners on both sides, a dust removal mechanism inside the main body, and a filter mechanism inside the vacuum cleaners. This invention uses two sets of plug-in rods to compress springs, connecting the bottom plug-in rods to a coupling via a dust removal cylinder. The plug-in rods, subjected to spring rebound, fix the mounting block inside the coupling. A servo motor drives the coupling to rotate, causing the dust removal cylinder to rotate inside the main body. This allows for dust removal of the plush toys placed inside the dust removal cylinder. Dust and broken hairs are discharged through slots inside the dust removal cylinder. This also allows for the removal of external dust and broken hairs from the plush toys, and facilitates easy installation, disassembly, and cleaning. The operation is simple, quick, and convenient.

[0004] The aforementioned patents have significant beneficial effects, but in practical application, they still have the following shortcomings:

[0005] The aforementioned comparative document describes a dust removal process where toys are placed in a dust collection cylinder. However, in reality, toy production lines produce a large number of toys in batches. If the dust removal device described in the document is used, the toys need to be manually placed into the dust collection cylinder, and then manually removed after dust removal. This reduces the efficiency of dust removal. Therefore, there is an urgent need in the art to improve the automatic dust removal device used in yarn toy production lines to address the shortcomings of the prior art. Summary of the Invention

[0020] 4. In this invention, by setting an anti-jamming unit, the first telescopic device drives several anti-jamming strips to move up and down between the conveying rollers, preventing the yarn toy from getting stuck between the two conveying rollers and improving the efficiency of conveying the yarn toy.

[0021] 5. In this invention, by setting up an adjustable brush roller, the efficiency of brushing the surface of the yarn toy is improved, and it can be applied to yarn toys of different sizes.

[0035] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, other embodiments obtained by those skilled in the art without creative effort are all within the scope of protection of the present invention.

[0036] Please see Figures 1-10 An automatic dust removal device for use on a yarn toy production line includes a dust removal box 1 fixedly installed between two conveying devices. Several horizontal conveying rollers 2 adapted to the conveying devices are rotatably connected inside the dust removal box 1. The conveying rollers 2 have arc-shaped protrusions 3 on their sides. An electrode plate 5 fixedly installed at the top of the dust removal box 1 is located in the middle of the dust removal box 1. Dust collection plates 6 adapted to the electrode plates 5 are fixedly installed on opposite side walls of the dust removal box 1. A dust scraping unit 4 is provided on the dust removal box 1 for scraping dust off the dust collection plates 6. Dust collection grooves 8 are opened on opposite side walls of the dust removal box 1, located below the dust collection plates 6, for collecting dust. A dust ejection unit 9 is provided on the side of the dust removal box 1 for ejecting dust from the dust collection grooves 8. A drive unit 7 is provided on one side of the dust removal box 1 for simultaneously driving several conveying rollers 2 to rotate. An anti-jamming unit 10 is provided at the bottom of the dust removal box 1 to prevent toys from getting stuck between two adjacent conveying rollers 2.

[0037] Specifically, the dust collector 1 is fixedly installed between two conveying devices in the yarn toy production line. The conveying devices are existing known technology. The conveying devices transport the produced yarn toys into the dust collector 1. The drive unit 7 drives several conveying rollers 2 to rotate. The conveying rollers 2 have protrusions 3 on their sides. The protrusions 3 cause the yarn toys to bounce up and down inside the dust collector 1, releasing dust from the surface of the yarn toys into the dust collector 1. At the same time, a negative voltage is applied to the discharge electrode plate 5. The air molecules between the discharge electrode plate 5 and the dust collecting electrode plate 6 are ionized into positive ions and electrons. As the electrons move towards the dust collecting electrode plate 6, they encounter dust particles in the airflow. When electrons combine with dust particles, the dust particles become negatively charged. The charged dust then travels to the positive dust collection plate 6, where it is adsorbed. This process removes dust from the yarn toys during transport, improving the efficiency of dust removal on the yarn toy production line. Simultaneously, the dust scraping unit 4 is activated periodically or manually. This unit scrapes the dust adsorbed on the dust collection plate 6 into the dust collection trough 8, and the dust ejection unit 9 pushes the dust out of the trough 8, achieving automatic dust cleaning. The anti-jamming unit 10 prevents the yarn toys from getting stuck between the two conveyor rollers 2, further improving the transport efficiency of the yarn toys.

[0038] As a technical optimization of the present invention, the dust scraping unit 4 includes a first drive motor 12 fixedly installed on the upper part of the dust collection box 1. The dust collection box 1 is provided with two scraper strips 13 whose sides are in close contact with one side of the dust collection plate 6. The upper side of the scraper strip 13 is rotatably connected to a threaded post 14 that penetrates the upper part of the dust collection box 1. The upper part of the dust collection box 1 is provided with a plurality of first transmission wheels 15. One first transmission wheel 15 is fixedly installed on the output end side of the first drive motor 12. Two first transmission wheels 15 are rotatably connected to the upper part of the dust collection box 1 and are threadedly connected to the threaded post 14. A first transmission belt 16 for transmission is sleeved between the sides of two adjacent first transmission wheels 15.

[0039] Specifically, when it is necessary to scrape off the dust adsorbed on the dust collection plate 6, the first drive motor 12 is started. The output end of the first drive motor 12 drives one of the first transmission wheels 15 to rotate. The first transmission wheel 15 drives the other two first transmission wheels 15 to rotate through the transmission of the first transmission belt 16. When the first transmission wheel 15 rotates, it drives the threaded column 14 to move up and down, thereby achieving the effect of scraping the dust adsorbed on the dust collection plate 6 into the dust collection groove 8.

[0040] As a technical optimization of the present invention, the drive unit 7 includes a second drive motor 17 fixedly installed on one side of the dust collector 1, a drive shaft 18 extending to the outside fixedly installed at the end of the conveying roller 2, a second transmission wheel 19 fixedly installed on the side of the drive shaft 18 located on the outside, a second transmission belt 20 for transmission is sleeved between the sides of adjacent second transmission wheels 19, and the output end of the second drive motor 17 is fixedly installed with one of the drive shafts 18.

[0041] Specifically, the second drive motor 17 is started, and the output end of the second drive motor 17 drives one of the drive shafts 18 to rotate. The drive shaft 18 drives the second transmission wheel 19 on its side to rotate. The second transmission wheel 19 drives the other second transmission wheels 19 to rotate in sequence through the second transmission belt 20. The second transmission wheels 19 drive the drive shaft 18 to rotate, thereby achieving the effect of simultaneously driving several conveyor rollers 2 to rotate.

[0042] As a technical optimization of the present invention, the dust ejection unit 9 includes a third drive motor 21 fixedly installed on one side of the dust collection box 1, a fixing plate 22 adapted to the third drive motor 21 fixedly installed on the side of the dust collection box 1, a drive screw 23 with one end fixedly installed to the output end of the third drive motor 21 rotatably connected between the two fixing plates 22, a matching dust pusher plate 24 sliding in the dust collection trough 8, a connecting rod 26 extending to the outside fixedly connected to one side of the dust pusher plate 24, a through groove 25 adapted to the connecting rod 26 opened on the side of the dust collection box 1, and a moving block 27 threadedly connected to the drive screw 23 fixedly connected to the outer end of the connecting rod 26.

[0043] Specifically, when it is necessary to push the dust out of the dust collection trough 8, the third drive motor 21 is started. The output end of the third drive motor 21 drives the drive screw 23 to rotate. When the drive screw 23 rotates, it drives the moving block 27 to move. When the moving block 27 moves, it moves in the through groove 25 through the connecting rod 26, which drives the dust pusher 24 located in the dust collection trough 8 to move, thereby pushing the dust out of the dust collection trough 8.

[0044] As a technical optimization of the present invention, the anti-jamming unit 10 includes a first telescopic device 28 fixedly installed at the bottom of the dust collector 1. A movable plate 29 is fixedly installed at the upper telescopic end of the first telescopic device 28. A plurality of anti-jamming strips 30 are fixedly installed on the upper part of the movable plate 29. The anti-jamming strips 30 are located between two conveying rollers 2 and the spacing between the two conveying rollers 2 is adapted.

[0045] Specifically, when conveying the yarn toy, the first telescopic device 28 is activated. The telescopic end of the first telescopic device 28 moves up and down intermittently. The output end of the first telescopic device 28 drives the moving plate 29 to move. The moving plate 29 drives several anti-jamming strips 30 located between the conveying rollers 2 to move up and down, preventing the yarn toy from getting stuck between the two conveying rollers 2 and improving the conveying effect of the yarn toy.

[0046] As a technical optimization of the present invention, a dust collection device 31 for dust collection is provided on the upper part of the dust collection box 1. A dust collection pipe 32 is fixedly installed on one side of the dust collection device 31, and a dust collection cover 33 located on one side of the dust collection box 1 is fixedly installed at one end of the dust collection pipe 32.

[0047] Specifically, the dust hood 33 is located at the tail end of the dust collection box 1. When the dust collection device 31 is activated, it absorbs a small amount of dust that has overflowed to the outside of the dust collection box 1 in cooperation with the dust collection pipe 32. The dust collection device 31 is a known technology that can collect dust.

[0048] As a technical optimization of the present invention, two second telescopic devices 34 are fixedly installed on the upper part of the dust collector 1. The telescopic tube of the second telescopic device 34 extends into the interior of the dust collector 1 and is fixedly installed with a fixed frame 35. The brush roller 11 is rotatably connected in the fixed frame 35. A fourth drive motor 36 for driving the brush roller 11 to rotate is fixedly installed on one side of the fixed frame 35.

[0049] Specifically, the surface of the brush roller 11 is provided with bristles. By starting the fourth drive motor 36, the output end of the fourth drive motor 36 drives the brush roller 11 to rotate, and the brush roller 11 brushes the dust off the surface of the yarn toy. At the same time, the position of the fixing frame 35 in the dust removal box 1 can be adjusted by the second telescopic device 34, which is suitable for yarn toys of different sizes.

[0050] As a technical optimization of the present invention, a plurality of limiting posts 37 are fixedly installed on the upper side of the scraper 13. The limiting posts 37 penetrate through the upper part of the dust collector 1. The limiting posts 37 limit the scraper 13 when it moves, so as to prevent the scraper 13 from deviating and squeezing the dust collection plate 6 when it moves.

[0051] As a technical optimization of the present invention, the scraper 13 is inverted L-shaped, and the inner sidewall of the scraper 13 is provided with a splash-proof angle 38 to prevent dust from splashing out when scraping off the dust from the surface of the dust collection plate 6.
