Description

Technical Field

[0001] The utility model belongs to the technical field of dust removal devices, and more specifically, particularly relates to a dust removal device for the surface of a hook and loop fastener. Background Art

[0002] Velcro is a commonly used connecting material for clothing. Velcro is generally divided into two sides, one side is a barbed structure with hooks, and the other side is a plush round structure. The two sides of the Velcro are bonded by touching and can be separated by pulling, making the fabric connection convenient and fast. Due to the complex hook-like structure arranged on the barbed surface of the Velcro, a large amount of broken hair and dust are easily accumulated inside the barbed surface during the storage period, affecting the hygiene quality of the Velcro and the sticky properties of the barbed surface. The existing technology often uses a brush to repeatedly scrape to remove dust and debris on the barbed surface, which is easy to damage the hook-like structure of the barbed surface and has poor results.

The suction airflow inside the dust hood sucks the Velcro dust into the filter bag. The air permeability and dust adsorption of polyester fiber are utilized to ensure the gas flow, and the dust is retained in the filter bag. The shrinkage at the bottom of the air duct sprays high-speed airflow to blow out the dust on the Velcro, thereby realizing the synchronous operation of air blowing and air suction dust removal of the Velcro, improving the dust removal efficiency of the Velcro, and avoiding the damage of the bristle surface caused by repeated scraping by a traditional brush.

[0023] When the utility model performs dust removal work on the Velcro, first manually rotate the knob 15, and the knob 15 drives the bidirectional threaded rod 22 to rotate. Since the two groups of adjustment frames 25 are respectively meshed and connected to the forward threaded end and the reverse threaded end of the bidirectional threaded rod 22, the bidirectional threaded rod 22 drives the two groups of adjustment frames 25 to move left and right oppositely, and the opposite spacing distance between the two groups of adjustment frames 25 can be flexibly changed according to the width of the Velcro. When the Velcro is dusted inside the dust cover 20, the entry of external dust into the dust cover 20 is reduced, and then the two ends of the Velcro are respectively wound around the outer sides of the driven drum 14 and the active roller 8, the driving motor 16 drives the active roller 8 to rotate, the active roller 8 drives the active sleeve 9 installed on the left end to rotate, the active sleeve 9 drives the driven sleeve 13 to rotate through the belt, and the driven sleeve 13 drives the driven The drum 14 rotates, and the driven drum 14 and the active roller 8 drive the Velcro to move from front to back, and the suction motor 19 drives the fan 18 to rotate. During the rotation of the fan 18, air flow movement is generated, and the air flow moves to the air cylinder 3 from the dust hood 20, the air inlet pipe 6, the filter bag 24, and the air outlet pipe 5 in sequence, and finally the air flow is discharged at a high speed at the shrinkage at the bottom of the air cylinder 3. During the movement of the Velcro from front to back, the sticky tape bonded to the outer side of the pressure rod 12 sticks to the dust on the surface of the Velcro, and when the Velcro passes through the bottom end of the air cylinder 3, the air cylinder 3 blows air to the upper side of the Velcro to blow out the dust on the Velcro, and when the Velcro passes through the dust hood 20, the suction airflow inside the dust hood 20 sucks out the residual dust on the Velcro, and the residual dust enters the filter bag 24 from the air inlet pipe 6 to complete the dust removal work of the Velcro.

[0024] The two-way threaded rod 22 is engaged with the threaded through hole of the convex plate of the left adjusting frame 25, and the reverse threaded end of the two-way threaded rod 22 is engaged with the threaded through hole of the convex plate of the right adjusting frame 25, so that the two-way threaded rod 22 drives the two groups of adjusting frames 25 to move left and right along the guide rod 26, and the width of the front edge and the rear edge of the dust hood 20 is adjusted according to the width of the Velcro, so that the bottom opening of the dust hood 20 matches the width of the Velcro to prevent the opening from being too large and causing dust to be sucked in.

[0025] In the disclosed embodiment, there are two groups of pressure rods 12, one group of pressure rods 12 is located on the front side of the air duct 3, and the other group of pressure rods 12 is located on the rear side of the dust hood 20. The outer side surface of each group of pressure rods 12 is covered with adhesive tape. When the pressure rods 12 flatten and squeeze the Velcro, dust in the Velcro is removed.

[0026] In the disclosed embodiment, the filter bag 24 is made of a bag structure made of polyester fiber cloth. Polyester fiber has good adsorption properties for dust and can effectively block the dust sucked into the air inlet pipe 6 in the filter bag 24.

[0027] In the disclosed embodiment, the bottom end of the air duct 3 is a tapered structure, and the bottom opening of the air duct 3 is opposite to the pad 17 in vertical direction. The tapered structure is utilized to increase the air flow rate of the exhaust of the air duct 3, so that the high-speed airflow at the bottom opening of the air duct 3 can blow out the internal dust of the Velcro placed on the pad 17.

[0028] In the disclosed embodiment, the bottom of the brush 21 is densely covered with a large number of vertical hairs, and the brush 21 is blocked on the front side of the dust hood 20. The bottom ends of the vertical hairs hang and rub the dust inside the moving Velcro to remove dust, and prevent the dust blown out from the bottom of the air tube 3 from scattering into the dust hood 20.

[0029] The installation, connection or setting methods of all the above components are common mechanical methods, such as welding, threaded connection, screw connection, etc., and the specific structures, models and coefficient indicators of all its components are its own technology, as long as it can achieve its beneficial effects, it can be implemented. The above-mentioned drive motor 16 and suction motor 19 are common components on the market. When you buy them back and use them, you only need to connect them according to the instruction manual purchased together, so I will not repeat them here.
