The invention provides a dust removal device which comprises a base, a draught fan support, a draught fan, a dust removal structure, a dust brushing structure, a rotating seal cap and a motor. The base is suitable for being fixedly arranged; the draught fan support is fixedly arranged on the base; the draught fan is fixedly installed on the draught fan support and comprises an air draft tube and fan blades installed inside the air draft tube, and the air draft tube is provided with an air inlet and an air outlet; the dust removal structure is arranged in the middle of the air draft tube and comprises a filter net and a dust collection box arranged on the side, close to the air inlet, of the filter net, and the position of the dust collection box is lower than the air draft tube; the dust brushing structure is used for brushing dust adhering to the side, facing the air inlet, of the filter net, and the dust falls into the dust collection box. According to the dust removal device, the dust removal structure is arranged in the middle of the air draft tube, the dust brushing structure is arranged, when dust removal needs to be conducted on the filter net, the dust brushing structure is started to conduct cleaning on the filter net, dust removal can be conducted without disassembling the dust removal device, the dust is easy to remove, and the labor intensity is low; the dust cannot fly around, workers cannot inhale the dust, and the health of the workers cannot be affected.

A filter dust collector is disclosed. The filter dust collector includes a housing, filter cloths fixed to an inside of the housing, a filter body part disposed inside the housing and having filter insertion holes, a compressed air supply part coupled to peripheries of the filter insertion holes, a transfer part connected to the filter body part to move the filter body part and the compressed air supply part in a longitudinal direction, a duct suction port formed on a side surface of the housing to suck air to be filtered, a supply port formed on a side surface of the housing to discharge filtered air, and a dust discharge port formed on a side surface of the housing, wherein the filter cloths are positioned at the filter insertion holes, the filter body part and the compressed air supply part move in the longitudinal direction, and the compressed air supply part sprays compressed air to the filter cloths.

A paper feeding apparatus transports paper one by one through a transportation mechanism to an image forming unit of an image forming apparatus. The paper feeding apparatus includes a paper feed cassette to contain paper, a paper side guide arranged in the paper feed cassette to position the paper in a direction perpendicular or substantially perpendicular to a transport direction of the paper, and a dust removing roller arranged in the paper side guide and in contact with the paper contained in the paper feed cassette.

Optical displacement sensor may possess light-emitting element(s) for projecting light onto distance measurement target(s), and light-receiving element(s) capable of receiving light reflected from distance measurement target(s) and disposed such that light-receiving surface(s) thereof is or are substantially perpendicular to optical axis or axes R1 of projected light. Furthermore, such optical displacement sensor(s) may be equipped with slit(s) capable of narrowing light beam(s) projected toward distance measurement target(s), and slit(s) capable of narrowing light reflected from distance measurement target(s).

A cleaner configured in such a manner that dust removal operation can be optimally performed without the removal of a front housing, without the entry of dust into the filter due to the dust removal operation, and without a decrease in the suction force. A cleaner (1), wherein a coiled spring (29) for pressing a filter (28) so that the filter is retained in an extended attitude is provided within the filter (28) of a filter unit (4), a mounting plate (30) is secured to the front end of the filter (28), one end of a wire (38) is connected to the mounting plate (30), and the other end of the wire (38) is led out of the inside of the filter (28) to the outside at the rear of the body housing after being made to pass through the body housing (2). The filter (28) can be arbitrarily contracted by causing, through pulling operation of the other end of the wire (38), the mounting plate (30) to recede against the pressing force of the coiled spring (29).

The invention discloses a clamping device capable of clamping parts of different shapes, comprising a casing, a control cavity is arranged in the casing, a motor is fixedly installed on the upper end face of the control cavity, and a motor is fixedly installed on the bottom end face of the casing Pentagonal plate, a power shaft is connected to the lower side of the motor, the power shaft penetrates and rotates to connect the lower side wall of the casing and the pentagonal plate, and the power shaft is fixed in the control cavity The driving wheel and the rotating wheel are installed. The device can be matched with the inclined block and the sliding rod, so that the driven wheel and the driving wheel are disengaged, and the number of clamping rods for clamping parts can be changed, so that parts of different shapes can be clamped. The parts are clamped and adsorbed by the clamping rod and the suction cup, and the parts are clamped more firmly.
