The invention discloses a powerful yarn clearer for a textile machine, which relates to the technical field of textile machinery and includes a machine body. The middle parts of both sides of the machine body are connected with a feed pipe and a discharge pipe, and the feed pipe and the discharge pipe are extended. In the machine body, a bellows is fitted with a gap between the outer circumference of the feed pipe and the discharge pipe in the machine body. One side of the bellows is fixedly connected to the inner wall of the machine body and the same connecting pipe is connected to the upper and lower ends. The connecting pipe is far away from the One end of the bellows is connected to the output end of the fan, and the fan is fixedly connected to the inner wall of the machine body. When cleaning a row of yarns, the present invention outputs to the surface of the yarn through two sets of fans, connecting pipes, bellows and air supply pipes. Against the wind, during the blowing process of the opposite wind, the two-way blowing and cleaning of the yarn surface is stronger than the cleaning effect of the one-way wind.

The invention discloses a tool for a CNC tool grinder. Its structure includes a positioning box, a fixing block, and a cooling pipe. The bottom of the fixing block is welded to the top of the positioning box. One end of the cooling pipe is embedded in the front side of the fixing block. The beneficial effects of the present invention The reason is that the rotating shaft is driven by the driving machine to rotate, and under the cooperation of the clamping groove and the block, the tool of the grinding machine is rotated to process the tool. The tool is processed by a block, so as to increase the processing power of the tool and facilitate the grinding of the tool. A large amount of waste chips are generated under the friction between the grinding machine tool and the processed tool. The waste chips are separated by the baffle to avoid the operator. Cause damage, under the suction of the magnetic block, the waste chips enter the chip discharge pipe and move up to the inside of the isolation chamber, and at the same time, the guide plate stores the waste chips for a short time to prevent the waste chips from falling back into the grinder.

The invention relates to the field of underwater construction equipment, in particular to an auger bit with an openable bottom baffle. The auger bit further comprises a spiral-vane bit shank, a centering sleeve at the bottom of the bit and cutter teeth. The auger bit is characterized by further comprising a tubular side baffle and at least two layers of horizontal baffles disposed at the bottom of the tubular side baffle. The tubular side baffle is fixed at the bottom of the bit shank. Each horizontal baffle is provided with an opening. The horizontal baffles relatively rotate to open or close the openings. With the openable bottom baffle, soil is prevented from falling back into a hole when the bit is turned out. In addition, the hollow shank and the through holes on the centering sleeve and the shank guarantee evacuation of the bottom of the hole when the bit is turned out, so that the problem of shrinkage is avoided.

The invention provides a high-efficiency lifting device for food processing, comprising a bottom plate, a lifting pipe is fixedly connected to the upper surface of the bottom plate, a power mechanism is provided on one side of the lifting pipe, and a second inner wall of the lifting pipe is movably connected to one side. A transmission roller, one side of the second transmission roller is movably connected with a conveyor belt, one side of the conveyor belt is fixedly connected with a plurality of tipping buckets, an inner wall of one side of the lifting pipe is movably connected with a first transmission roller, and the first transmission roller is movable with the conveyor belt Both ends of the first transmission roller are fixedly connected with a disc, and one side of the disc is fixedly connected with a swing rod. The invention can not only scrape and lift the material at the bottom of the lifting pipe to the top of the lifting pipe through the tipping bucket, save human resources and improve the work efficiency, but also can avoid the material falling back to the bottom again, improve the work efficiency of the device, and can The phenomenon of slipping and shaking of the device is prevented, and the stability of the device is improved.

The invention discloses a numerically controlled lathe with an alarm function. The structure includes a numerically controlled body, a control panel, an observation port and a base. The numerically controlled body includes a motor, a fixture, a baffle, a material guide belt, a separation device, a water pipe, and a transmission machine. , the guide belt includes a positioning rod, a runner, an isolation belt, and a waste chute; the isolation belt includes a guide plate, an isolation plate, and a waste chamber; the separation device includes a conveyor belt, a bite groove, a drive shaft, and a support rod; Rollers, teeth, and support rods include fixed blocks and brushes. When the water level alarm device sounds, the conveyor is started. Because the bite grooves on the inside of the conveyor belt and the teeth engage with each other, the drive drives the drive shaft to rotate, and the drive shaft rotates to drive the isolation belt. Rotate, the isolation belt will bring the waste chips in the waste chip chute to the separation device, and a brush is installed on the support rod. Chips block the water pipe, so as to avoid the accumulation of coolant and cause the CNC machine body to rust.

The invention provides an underground floater cleaning grass fisher. The grass fisher comprises a disc, a tray, a grass fisher rod, a first inner tube, a tray tightening wire and multiple mechanical grabbers, each mechanical grabber comprises a detecting leg, a detecting leg cross arm and a detecting tongue, one end of each detecting leg cross arm is caught on the tray and faces the center of thetray, the other end of each detecting leg cross arm is fixed to the upper end of the corresponding detecting leg and hinged to the edge of the disc together with the detecting leg, the included angleof each detection leg cross arm and the corresponding detecting leg is smaller than 90 degrees, each detecting tongue is installed at the lower end of the corresponding detecting leg through a rotating shaft, the free end of each detecting tongue faces the axis of the disc and can rotate around the rotating shaft to reach the horizontal position to the lowest. The grass fisher is low in cost, lowin weight, easy to operate and convenient to use, and has a good application prospect.

The invention provides a quilt basking device, belongs to the technical field of machinery, and solves the technical problems of low sunlight utilization ratio during quilt baking in the prior art. The quilt basking device comprises a rectangular plate-shaped quilt basking plate, wherein the quilt basking plate is arranged in the horizontal direction; a clip for clamping a quilt is arranged on the upper surface of the quilt basking plate; a flapping mechanism for flapping the surface of the quilt is arranged on the upper surface of the quilt basking plate; a plurality of through holes allowing light rays to pass through are formed in the surface of the quilt basking plate. The quilt basking device further comprises a bottom plate parallel to the quilt basking plate; the bottom plate is positioned under the quilt basking plate; the bottom plate and the quilt basking plate are fixedly connected through four supporting columns. The quilt basking device also comprises at least one inclined first reflecting plate; the inner end of the first reflecting plate and the side wall of the bottom plate are connected into a whole and form an obtuse angle; the outer end of the first reflecting plate extends slantways and upwards; a second reflecting plate is also fixed on the upper surface of the bottom plate.
