The present invention provides a substrate double-surface hole-filling apparatus for carrying out a hole-filling operation on a substrate which has a first surface and a second surface, comprises a first feeding device, a first scraping device, a first drying device, a second feeding device, a second scraping device, a second drying device and a turnover device. The substrate double-surface hole-filling apparatus has a turnover device turning over the substrate which needs to be carried out with hole-filling operation. Therefore, the substrate double-surface hole-filling apparatus can automatically carry out the hole-filling operation on two surfaces of the substrate without manual turnover of the substrate, thus improving production efficiency.

A roll-to-roll electroless plating system, including a plating tank containing plating solution, and a web advance system for advancing a web of media along a web-transport path that passes through the plating tank. One or more fluid guides are positioned within the plating tank to redirect plating fluid containing gas bubbles introduced by a gas bubble source away from the web of media as it is advanced through the plating solution in the plating tank.

A swimming pool cleaning system for removing stains and deposits on the bottom and walls of a swimming pool. The cleaning system includes a cleaning tool having an elongated handle pivotally secured to a tool head, wherein the tool head dispenses a cleaning solution for removing stains and deposits. The tool head may also include an absorbent or sponge-like material thereon and one or more scrapers to help remove deposits. The tool head is in fluid communication with a container in which a cleaning solution can be stored. The container includes a pump thereon for allowing the user to selectively deliver the cleaning solution to the cleaning tool. Thus, the cleaning system allows a user to more easily remove stains and deposits from the walls and bottom of a pool.

A web transport system for transporting a web of media along a web-transport path including a fluid bar for guiding the web of media, and a scavenger blade positioned downstream of the fluid bar. A liquid is pumped through holes in an exterior bearing surface of the fluid bar, thereby pushing the web of media away from the fluid bar. The scavenger bar includes a blade edge facing the first surface of the web of media, the blade edge being spaced apart from the first surface of the web of media by a gap distance. The scavenger blade removes at least some liquid from the first surface of the web of media as it passes by the scavenger blade, thereby reducing the amount of liquid that is carried along to portions of the web-transport path that are downstream of the scavenger blade.

The present invention relates to an apparatus for processing a film by a squeezing force, including a stand, a soaking tank, as well as a feeding shaft, a roll shaft, a stepping motor and a scraping mechanism mounted to the stand, respectively, wherein the rotatable pressure roll shaft presses the film to the soaking tank; the scraping mechanism includes a first scraping shaft and a second scraping shaft which are connected to the stepping motor; an optocoupler switch is fixed to the stand; the stepping motor automatically finds the initial position via the optocoupler switch; and the stepping motor automatically adjusts the position and angle of the scraping mechanism according to a parameter.

The present disclosure provides a scraping device (700) for a stencil printer comprising: a scraper holder (710), a scraper (720) having a travel path for squeegeeing a material to be dispensed on a stencil (130), the scraper (720) being arranged oblique to the stencil (130) and to the rear of the travel path; a mounting assembly (730) configured to mount the scraper (720) to the scraper holder (710). The mounting assembly (730) is further configured to be able to adjust the inclination angle of the scraper (720) relative to the stencil (130) and to maintain the scraper (720) at an adjusted angular position.
