The invention discloses a print head module and a label printer. The print head module comprises a flat plate, a fixation frame and a spring sheet. A print head is arranged on the flat plate; and the spring sheet has a first end and a second end which are opposite, wherein the first end realizes fixation connection with the flat plate through combination and fixation of a first fixation portion and a second fixation portion, which are different in position and coplanar, of the first end with a first fixation member and a second fixation member of the flat plate; and the second end realizes fixed combination with the fixation frame through combination and fixation of a third fixation portion and a fourth fixation portion, which are different in position and coplanar, of the second end with a third fixation member and a fourth fixation member of the fixation frame, such that the two ends of the print head are equally stressed, the problems of wrinkling, paper jam and light-color printing due to unequal stress of the print head are prevented, and deflection is guaranteed.

The invention relates to a tooth chamfer tester of a tooth ring, and belongs to the technical field of tooth rings. The tester comprises a column arranged on a pedestal, the pedestal is supported by supporting legs, the pedestal is provided with a through hole for placing the tooth ring and at least three groups of spherical supporters, each group of spherical supporters supports the two side surfaces of a chamfer of the same tooth in the tooth ring, a positioning mandrel is further included, one end of the positioning mandrel is provided with a positioning cylinder matching the inner ring ofthe tooth ring, and the positioning mandrel and the positioning cylinder are arranged on the column in an up-down sliding way. Thus, detection time for the tooth chamber is shortened, the detection efficiency is improved, and the cost is reduced.

A powered tool constructed to drive a fastener into a workpiece includes a nosepiece assembly including a back plate and a front plate combining to define a path for a driver blade, the front plate being pivotally movable relative to the back plate between a closed position, in which the front plate and the back plate are in contact with each other, and an open position. The front plate is movable to an interim deflecting position between the closed position and the open position. A handle portion has an outer surface at least partially defining a grip, and an inner surface at least partially defining a chamber. The handle portion includes a substrate having at least one aperture, and an overmold configured for forming a gripping surface on the outer surface and for extending through the apertures into the chamber for forming a resilient mounting point.

The invention relates to a method for cutting and processing aluminum-plastic panels for building curtain walls, and relates to the technical field of building material preparation. A pressing device that is pressed onto the alignment device and a cutting device that cuts the aluminum-plastic panel, the alignment device includes a loading plate that is rotatably installed on the operating table, and one side of the loading plate is provided with a The table is rotatably installed, and the pressing device includes a fixed plate arranged on the first baffle plate and the second baffle plate. The present invention has the effect of higher efficiency and faster production in the actual cutting process.

The invention relates to a lint cotton opening device. The lint cotton opening device comprises an opening roller, an upper opening shell, a lower opening shell, a lint cotton throwing curve, a variable-frequency motor, a frequency converter, a spiked nail conveying belt and a transverse adjustable bearing seat. The upper opening shell and the lower opening shell are connected together via a sealing gasket to form an opening shell. The lint cotton throwing curve is mounted on the outlet side of the opening shell. The opening roll shaped in a cylinder is positioned at the inner center of the opening shell and portioned into an outer layer and an inner layer. The spiked nail conveying belt is capable of cooperating with a lint cotton scraping and evening plate to hook and pull lint cotton so as to preopen the lint cotton while conveying the to-be-checked lint cotton. The lint cotton opening device has the advantages that cotton bales can be fully opened via striking of spiked round-headed nails and rubbing of a bottom-shell fence structure, damage to cotton fibers is small, and foreign fiber trait is kept well.

A system for taking exhaust gas samples from internal combustion engines includes an exhaust gas duct comprising an outflow cross section and an exhaust gas inlet. The exhaust gas duct communicates with an exhaust gas source via the exhaust gas inlet. An air duct takes in ambient air via a filter. The outflow cross section is concentric in the air duct. A mixing zone is arranged downstream of the outflow cross section. A dilution tunnel has an exhaust gas / air mixture flow therethrough. An annular orifice is arranged downstream of the outflow cross section in the dilution tunnel. A flow deflection device is arranged upstream of the annular orifice and downstream of the outflow cross section. The flow deflection device deflects the exhaust gas / air mixture so that it departs from a center axis of the dilution tunnel immediately downstream of the flow deflection device in an axially symmetrical manner.

The invention discloses a rubbish can cleaning system and belongs to the technical field of environmental sanitation equipment. The rubbish can cleaning system comprises a driving source, a power spindle, a rotating arm, a rinsing assembly and a spraying mechanism. The rinsing assembly comprises a driving motor, a fixed base, a rotating shaft and a cleaning brush. The axis of the rotating shaft is perpendicular to the extension direction of the rotating arm. A fixed clamping sleeve is fixedly mounted at the end of the rotating arm, and a deflection assembly is fixedly sleeved with the fixed clamping sleeve. The fixed base is fixedly connected with a pair of connecting lug plates. The deflection assembly comprises a central spindle and an outer sleeve body, and the outer sleeve body is sleeved with the fixed clamping sleeve. The cross section of a hollow cavity of the outer sleeve body is square, and the four side faces of the central spindle right face the four corner sides of the hollow cavity of the outer sleeve body. Rubber bodies are plugged between the side faces of the central spindle and the corner sides of the hollow cavity of the outer sleeve body. The two ends of the central spindle are detachably connected with the connecting lug plates. The rubbish can cleaning system can ensure that the cleaning brush has deflection capacity, and accordingly the phenomenon that the outer wall of a rubbish can is abraded due to overlarge contact acting force between the cleaning brush and the outer wall of the rubbish can is avoided.
