Abstract
Description
Technical Field
[0001] This utility model relates to the field of net curtain cleaning technology, and in particular to an automatic net curtain cleaning device. Background Technology
[0002] Currently, in the nonwoven fabric production process, a suction fan tightly attaches the yarn bundles from the yarn feeder to the mesh curtain. Then, as the mesh curtain rotates, it is conveyed forward to form the finished product. Over time, due to production processes and environmental factors, a large amount of dust, airborne fibers, and other debris accumulates on the mesh curtain, clogging the mesh openings and weakening the suction effect. This results in uneven mesh laying, affecting product quality and causing varying degrees of reduction in uniformity and strength.
[0003] Existing methods for cleaning mesh curtains typically involve manual cleaning, cleaning brushes fixed to the outside of the mesh curtain, or cleaning rollers mounted on the outside of the mesh curtain. Manual cleaning is time-consuming, labor-intensive, and affects production efficiency. The cleaning direction of the cleaning brushes and rollers is fixed, and some fibers extend along the cleaning direction, or dust remains on the mesh curtain through the gaps in the cleaning brushes or rollers, causing more and more debris to accumulate on the mesh curtain, which seriously affects the suction effect and product quality.
[0004] Therefore, an automatic cleaning device for net curtains that can continuously change the cleaning direction is needed. Utility Model Content
[0005] This invention addresses the shortcomings of existing technologies by providing an automatic cleaning device for net curtains. This device uses a drive mechanism and a reciprocating motion mechanism to drive a cleaning brush to reciprocate on the net curtain, thereby continuously changing the cleaning direction of the brush and improving cleaning efficiency. It is simple, efficient, safe, reliable, and easy to operate.
[0006] This utility model is achieved through the following technical solution: It provides an automatic cleaning device for a mesh curtain, including a support frame with a cleaning brush mounted on it. The cleaning brush is located on the outer side of the mesh curtain and is fitted close to it. The support frame has a slide rail parallel to the mesh curtain, and the angle between the axis of the slide rail and the transmission direction of the mesh curtain is greater than 0°. The cleaning brush slides on the slide rail, and the support frame has a drive mechanism that drives the cleaning brush to reciprocate along the slide rail via a reciprocating motion mechanism. The drive mechanism and the reciprocating motion mechanism drive the cleaning brush to reciprocate on the mesh curtain, thereby continuously changing the cleaning direction of the cleaning brush and improving cleaning efficiency.
[0007] As an optimization, a rotating shaft extending axially along the slide rail is mounted on the bracket, and the slide rail is fixed on the rotating shaft. The rotating shaft is connected to the drive roller of the mesh curtain through a transmission mechanism, and the rotating shaft and the drive roller are located on opposite sides of the mesh curtain. The transmission mechanism connects the rotating shaft and the drive roller of the mesh curtain, thereby causing the cleaning brush to rotate and the direction of rotation of the cleaning brush to be opposite to the transmission direction of the mesh curtain, thereby increasing the relative sliding distance between the cleaning brush and the mesh curtain and improving the cleaning effect.
[0008] As an optimization, the reciprocating motion mechanism includes a driving bevel gear coaxially fixed on a rotating shaft. The driving bevel gear meshes with a driven bevel gear whose axis is perpendicular to the axis of the rotating shaft. The driven bevel gear is hinged to a slider via a transmission rod. The hinge axis of the transmission rod is parallel to the axis of the driven bevel gear, and the transmission rod is hinged at a position of the driven bevel gear away from the axis. The slider slides on the rotating shaft, and a through hole is opened on the slider, with the rotating shaft rotating within the through hole. The slider is connected to a cleaning brush. By connecting the reciprocating motion mechanism and the rotating shaft, the rotation of the rotating shaft and the reciprocating motion of the cleaning brush share the same drive mechanism, reducing the cost of cleaning the screen curtain.
[0009] As an optimization, the driven bevel gears are arranged opposite each other and located on both sides of the driving bevel gear; the stability of the reciprocating motion of the cleaning brush is increased by the driven bevel gears arranged opposite each other on both sides of the driving bevel gear.
[0010] As an optimization, a fan A is installed on the inside of the mesh curtain, and the air outlet of the fan A faces the cleaning brush; the air outlet of the fan A causes the part of the fibers, feathers and other debris that is not attached to the mesh curtain to float towards the cleaning brush, thereby improving the cleaning effect.
[0011] As an optimization, a fan B is provided on the outside of the mesh curtain, and a cleaning brush is located at the air inlet of the fan B; debris falling from the mesh curtain is collected through the air inlet of the fan B, preventing debris from re-adhering to the mesh curtain and improving the cleaning effect.
[0012] The beneficial effects of this utility model are as follows: the driving mechanism and reciprocating motion mechanism drive the cleaning brush to reciprocate on the mesh curtain, thereby continuously changing the cleaning direction of the cleaning brush and thus improving cleaning efficiency. The transmission mechanism connects the rotating shaft and the transmission roller of the mesh curtain, thereby causing the cleaning brush to rotate and making the rotation direction of the cleaning brush opposite to the transmission direction of the mesh curtain, thereby increasing the relative sliding distance between the cleaning brush and the mesh curtain and improving the cleaning effect. The reciprocating motion mechanism is connected to the rotating shaft, so that the rotation of the rotating shaft and the reciprocating motion of the cleaning brush share the same driving mechanism, reducing the cleaning cost of the mesh curtain.
