The application discloses a high-precision structure printing plate roller grinding machine, which comprises a protection module for supporting and protecting the device, a clamping module for clamping and driving the printing plate roller, a grinding module for grinding the surface of the printing plate roller, a distance adjusting module for adjusting the distance between the grinding module and the printing plate roller according to the diameter of the printing plate roller and a cooling module for setting the cooling of the printing plate roller, wherein the protection module comprises a protection shell, and the clamping module comprises a clamping piece. The distance between the grinding module and the printing plate roller can be accurately adjusted according to the need through the distance adjusting module, the application range of the device is improved, the linkage between the driving roller and the screw rod can save the power source, which is favorable for saving the manufacturing cost, the water spraying can be blocked through the water baffle and the baffle, the water splashing is avoided, and the phenomenon of the staff is not favorable.

The application belongs to the technical field of spinning frame, especially a single spindle roving feeding self-stopping device. The existing yarn spindle to be replaced still needs to be placed manually, which undoubtedly increases the labor of workers and is low in efficiency and inconvenient to use. The present application proposes the following scheme, which comprises a spinning frame, one side of the spinning frame is provided with a replacement frame, the replacement frame is provided with two groups of yarn spindle holders for alternate use; the replacement frame comprises a first support and a second support fixedly arranged on the ground, and a rotating rod is arranged between the first support and the second support. In the application, the cooperation of the feeding box, the conveyor and the replacement frame can drive the empty tube to move below the yarn spindle holder and drive the yarn spindle holder on one side to rotate and insert into the empty tube. At the same time, the empty tube can be brought to the right position without manual placement. In the process of rotating the yarn spindle holder on one side, the tube yarn on the yarn spindle holder on the other side will automatically fall into the collecting box without manual unloading, which is more convenient to use.

This invention relates to an asphalt pavement repair device, belonging to the field of pavement repair technology. It includes a pavement, a repair groove carved into the pavement, two counterweights, and a vehicle body. The vehicle body is positioned on the pavement and located on one side of the repair groove. The two counterweights are located on opposite sides of the repair groove, and a common first screw connects the two counterweights. A first motor is fixedly connected to the inner wall of one side of one of the counterweights. This invention uses a second motor to drive a connecting plate downwards to compact the repair material. Simultaneously, it uses a jaw to drive a punching rod to press a punching plate, further compacting the repair material and preventing it from sticking to the backflow box and the punching plate. The first screw not only moves the vehicle body across the repair groove but also moves the spray nozzle back and forth for even spraying and moves the compaction plate up and down to further compact the repair material within the repair groove, reducing the need for an additional power source.

This utility model relates to the technical field of tree pruning devices, and discloses a garden tree pruning clamp saw, including a fixed base, a fixed claw clamp and a movable claw clamp on the fixed base, the fixed claw clamp being fixed to the fixed base; a slide block is slidably mounted on the fixed base, and the movable claw clamp is driven to the slide block through an elastic connector; the movable claw clamp is located between the slide block and the fixed claw clamp; a power mechanism is installed on the fixed base to drive the slide block to move closer to or away from the fixed claw clamp, and the power mechanism is driven to the slide block; an electric saw is rotatably mounted on the slide block, and the electric saw is driven to the movable claw clamp through a linkage mechanism, the linkage mechanism being used to drive the electric saw to rotate. This utility model, when the movable claw clamp moves closer to the fixed claw clamp and clamps the tree trunk, drives the electric saw to rotate through the linkage mechanism, thereby achieving tree trunk pruning, reducing the power source, and lowering power consumption; at the same time, the mechanical transmission eliminates the need for pipelines, the structure is simple, not easily damaged, and has good practicality.
