Description

Technical Field

[0001] The utility model relates to the technical field of non-woven fabric processing machinery, in particular to a dust removal and sterilization device for non-woven fabric processing. Background Art

[0002] Non-woven fabric dust removal usually uses a large area of ​​air blowing in the dust removal box to separate the dust attached to the non-woven fabric from the non-woven fabric, and discharges the raised dust through the negative pressure adsorption tube installed on the top of the box. The distance between the adsorption tube and the non-woven fabric is large, and a wide space is required for adsorption. A large suction force is required to ensure the dust removal effect during adsorption. However, the greater the suction force, the greater the noise. The noisy sound affects the working environment of employees. The large distance between the adsorption tube and the non-woven fabric also makes it difficult to completely adsorb the dust.

The air outlet end of the air supply pipe is connected to the inside of the air outlet pipe, and the air inlet of the air supply pipe passes through and is fixedly arranged on the rear end surface of the outer box. The ultraviolet lamp is arranged on the inner wall of the outer box above and / or below the non-woven fabric on the discharge side of the inner box.

[0006] A further improvement is that an auxiliary structure is provided inside the outer box for increasing the ultraviolet irradiation time of the non-woven fabric to improve the sterilization effect.

[0007] A further improvement is that the auxiliary structure is a plurality of guide rollers staggered up and down for the non-woven fabric to be wound around in sequence to increase the longitudinal stroke, and the guide rollers are rotatably arranged on the inner wall of the outer box.

[0008] Further improvements are: the air outlet duct is a hollow cylinder with two end faces tightly fitted together, a fixed seat is provided at the lower end of the air outlet duct, the fixed seat is fixedly arranged at the bottom of the inner box, an arc groove adapted to the outside of the air outlet duct is opened on the upper end face of the fixed seat, the air outlet duct is horizontally fixed on the fixed seat, a number of air outlets are evenly opened on the upper end of the air outlet duct, an interface communicating with the outside is provided on the rear end face of the air outlet duct, and the air outlet end of the air supply pipe is connected to the interface.

[0009] A further improvement is that: the number of the air outlet tubes is two, the air supply pipe is a Y-shaped connecting pipe, the two symmetrical air outlet ends of the Y-shaped connecting pipe are respectively connected to the interface, and the air inlet of the Y-shaped connecting pipe is connected to the branch fan.

[0010] A further improvement is that the adsorption tube is a corrugated tube that can adapt to the up and down movement of the box cover.

[0011] A further improvement is that a feed channel and a discharge channel are fixedly arranged on the outer wall of the inner box at the inner feed port and the inner discharge port respectively, and a pair of restraining rollers are rotatably arranged in the feed channel and the discharge channel for restraining the upper and lower positions of the non-woven fabric to prevent the non-woven fabric from moving up and down due to wind force and causing wear on the box body of the inner box, and a restraining gap is formed between the pair of restraining rollers for the non-woven fabric to pass through.

[0012] A further improvement is that: inside the outer box, clamping rollers for clamping and conveying non-woven fabrics are rotatably arranged on the outer feed port and the inner feed port respectively, the two ends of the clamping rollers are rotatably arranged on the inner wall of the outer box, and a driving structure for synchronously driving two groups of clamping rollers is arranged on the outer wall of the outer box.

[0013] By adopting the above technical solution, the beneficial effects of the utility model are:

Only the inner feed port and the inner discharge port of the inner box are connected to the outer box. When the adsorption tube is working, the gas in the outer box will enter the inner box along the feed channel and the discharge channel, preventing dust from escaping from the inner box and adsorbing on the inner wall of the outer box.

[0015] 2. In this case, the cover of the inner box is detachable to facilitate the winding of non-woven fabric and cleaning of the inner box. The adsorption tube adopts a corrugated tube, which can be well used for the disassembly and assembly of the cover.

[0016] 3. In this case, an auxiliary structure is set up, through a number of guide rollers staggered up and down, the ultraviolet irradiation time is increased by increasing the longitudinal stroke without increasing the lateral stroke, thereby improving the sterilization effect.

[0017] 4. In this case, the air outlet tube arranged at the bottom of the inner box can be close to the non-woven fabric and blow air directly to the lower surface of the non-woven fabric. Under the action of the restraining roller, the non-woven fabric will not float over a large range and cause wear to the inner box. BRIEF DESCRIPTION OF THE DRAWINGS
