The utility model discloses a carding machine with a creeling structure, which belongs to the technical field of carding machines and is characterized by comprising a carding machine body, a control panel is arranged on the left side of the carding machine body, a support frame is fixedly connected to the front side of the carding machine body, and a switching component is rotatably connected to the inside of the support frame. The switching assembly comprises a connecting block, a positioning assembly is arranged in the connecting block, a cotton barrel is arranged on the surface of the positioning assembly, by arranging the positioning assembly, after the cotton barrel is connected to the surface of the connecting block in a sleeving mode, a trapezoidal block can extrude an inclined block when moving, and the inclined block can drive a positioning rod to move towards the side away from the trapezoidal block after being stressed; the positioning rods can move into the positioning grooves, so that the position of the cotton barrel can be limited, the phenomenon that the cotton barrel deviates and falls in the winding process is avoided, when the cotton barrel needs to be taken down, the trapezoidal blocks are reset, then the cotton barrel can be taken and placed quickly, and the convenience during barrel replacement is improved.

The utility model discloses a bearing device and pipe replacing equipment. The bearing device comprises a base, a first supporting piece and a second supporting piece. The first supporting piece is slidably connected with the base, and the sliding direction of the first supporting piece relative to the base is set as a first direction; the first supporting piece is provided with a first surface used for supporting one end of a pipe. The second supporting piece is connected with the base, and the second supporting piece and the first supporting piece are arranged in the first direction; the second supporting piece is provided with a second surface, the second surface is used for supporting the other end of the pipe, and the roughness of the second surface is smaller than that of the first surface. According to the supporting device, the supporting stability of the quartz tube and the moving convenience of the quartz tube can be both considered.

The present application discloses a baking paper uninterrupted full-automatic continuous pipe changing and rewinding device, relates to the rewinding device field, including the shell, the inner wall fixed mounting of shell has the fixed roller, the outer wall of fixed roller rotationally connects the winding drum, the side of shell is provided with the clamping mechanism, the clamping mechanism includes the fixed plate, the fixed plate one side fixed mounting has the No. 1 air cylinder, the No. 1 air cylinder one end fixed mounting has the No. 1 rack, the outer wall of No. 1 rack is engaged with the gear, the outer wall of gear is engaged with the No. 2 rack.The present application is provided with four groups of rubber blocks, because four groups of rubber blocks are rubber material, rubber material has elasticity, and then can better fit the inner wall of winding drum, secondly, rubber material has greater friction, can more firmly support the inner wall of winding drum and clamp, prevent falling when moving the winding drum.

The utility model discloses a quick pipe replacing device which comprises a pipe replacing support, a connecting support is arranged below the pipe replacing support, two connecting rods are detachably connected to the connecting support through a U-shaped plate, the two ends of each connecting rod are connected with idler wheels, a communicating pipe is fixedly connected to the pipe replacing support, and the communicating pipe is connected with a telescopic inner pipe through a flange. A telescopic inner pipe is arranged on the guide rail, a telescopic sleeve is arranged outside the telescopic inner pipe in a sleeved mode, a first connecting base is arranged on the telescopic inner pipe, a second connecting base is arranged on the telescopic sleeve, and the first connecting base and the second connecting base are connected through a hydraulic telescopic rod. Relative movement between the telescopic sleeve and the telescopic inner pipe is achieved in cooperation with the hydraulic telescopic rod, so that the mud pipe can be rapidly replaced, the stability of the whole pipe replacing device is enhanced by arranging the overturning-preventing support, and the situation that the pipe is accidentally inclined or overturned in the pipe replacing process is prevented.

The present invention provides a pressing assembly and a guiding sheath, relating to the field of medical devices. The present invention includes a deformable tube, and the deformable tube is communicated with a reflux joint; the deformable tube includes an elastic tube, and the elastic tube is made of an elastic material. When the deformable tube is subjected to force, the elastic tube bends, so that the flow cross-section inside the elastic tube changes, thereby changing the flow rate of the elastic tube. Compared with the prior art, the present invention realizes the adjustment of the flow rate of the reflux channel by controlling the bending degree of the elastic tube, making the flushing process more controllable. By optimizing the fluid flow state in the reflux channel, the present invention can, to a certain extent, reduce the fluctuation of the internal pressure in the body, reduce the potential damage risk to tissues, and at the same time improve the effect of lithotripsy flushing and discharge, and improve the safety and stability of medical operations.

This utility model discloses an automatic electrode changing nozzle locking mechanism for EDM drilling, including a rotating shaft bearing mounting base B and a spring. The left side of the rotating shaft bearing mounting base B is provided with a guide rod cylinder mounting base. The rotating shaft bearing mounting base B has two guide rod cylinders. A cylinder connecting plate is connected to the bottom of the rotating shaft bearing mounting base B. A rotary lifting sliding bearing is movably connected to the bottom of the cylinder connecting plate. A steel pipe rotating shaft is movably connected to the rotary lifting sliding bearing. A locking nozzle lifting sleeve is movably connected to the steel pipe rotating shaft. A manual grip wheel is fitted on the steel pipe rotating shaft. This utility model uses two springs for locking, increasing the locking effect and further ensuring the normal operation of the equipment.
