The invention relates to the technical field of shredding machine blade replacement, and discloses a shredding machine blade quick replacement mechanism which comprises a rotating roller, a pre-positioning mechanism is arranged on the outer side of the rotating roller, and a fixing mechanism is arranged in the rotating roller; the pre-positioning mechanism comprises a plurality of fixing frames, the inner wall of each fixing frame is fixedly connected with the outer surface of the rotating roller, two cutter bodies are slidably connected to the inner wall of each fixing frame, positioning columns are fixedly connected to the side faces, close to each other, of each set of cutter bodies, and the outer surface of each positioning column is slidably connected with the inner wall of the corresponding fixing frame. According to the rapid replacement mechanism for the shredder blade, by arranging the fixing frame, a stable mounting and bearing foundation can be provided for the cutter body, meanwhile, pre-positioning of the cutter body is achieved in cooperation with the magnetic attraction effect of a positioning column and a powerful magnet, and when an operator slides the cutter body into the fixing frame, the positioning column can move along the guide track of the fixing frame; and the adsorption force is generated.

The application belongs to the technical field of galvanized steel wire production, and discloses a production device and process for galvanized steel wire, which comprises a table top provided with a frame on the top, an adjusting mechanism arranged above the frame, and a scraping mechanism arranged inside the frame, wherein the adjusting mechanism comprises movable blocks, the number of the movable blocks is two, and the two movable blocks are respectively fixedly installed on the two sides of the top of the frame. By setting the air cylinder, the push-pull block, the first circular block and the movable blocks, the push-pull block drives the first circular block to move left or right by starting the air cylinder, so that the two movable blocks drive the two drive motors to move towards or away from each other, thereby the spacing of the two brushes can be adjusted, the brushes can better fit the steel wires of different diameters, the steel wires can be well brushed and cleaned, the cleaning effect of the steel wires is improved, and the subsequent galvanizing processing quality is improved.

The utility model discloses an automatic tool changer for a CNC (computerized numerical control) machining center, which relates to the technical field of CNC milling machines and comprises a machining table, a machining mechanism is mounted on the inner side of the machining table, a tool is detachably mounted on the machining mechanism through a mounting seat at the bottom of the machining mechanism, and a tool changing component is arranged on the mounting seat. According to the automatic tool changer for the CNC machining center, by arranging the tool changing assembly, when a tool is mounted, the tool is upwards inserted into the inner side of a mounting base to push a lifting rod to move upwards, then through linkage of the lifting rod, a rack, a gear, a pushing piece and a movable plate, all clamping rotating blocks are pushed to rotate together and clamped to the inner side of a mounting groove of the tool, and the tool is mounted in the mounting groove; therefore, the situation that the clamping effect of the cutter is unstable due to the fact that the soft block and the soft strip are clamped and limited and lose elasticity and even are damaged due to friction in long-term use is avoided, and the machining effect is also guaranteed.

This utility model relates to a crystal head testing and error-proofing device in the field of crystal head error-proofing technology. It includes a processing table with a rectangular hole. A rectangular plate is rotatably connected inside the rectangular hole via a pair of rotating shafts. When adjusting the angle of the crystal head, the moving frame must be manually pulled upwards to remove the lower end of the connector from the insertion slot. Simultaneously, the connector block pulls up a spring, causing it to be stretched further. Then, the rectangular plate is rotated up and down, causing the crystal head to rotate up and down as well, thereby adjusting the angle of the crystal head. After adjusting the angle, the external force applied to the moving frame is removed, causing the spring to pull the connector block, the moving frame, and the connector downwards together, allowing the lower end of the connector to be inserted into the corresponding insertion slot, thus fixing the rotating shaft and the rectangular plate. This application provides a simple and time-saving procedure for adjusting the crystal head, making it convenient for personnel to use when processing and testing crystal heads.

The utility model discloses a filter screen plate structure in a coal gas heater in the technical field of coal gas heaters, which comprises a heating box, a heat exchange tube is arranged in the heating box, a filter screen plate body is movably mounted on the inner wall of the heating box, a square box is fixedly mounted at the front end of the filter screen plate body, and a filter screen plate is arranged in the square box. The other end of the square box penetrates through the heating box and is fixedly connected with a baffle. Through the arrangement of the clamping groove, the inserting plate and the limiting assembly, when a worker needs to detach the filter screen plate body for cleaning, the inserting plate can move through the limiting assembly and is pulled out of the clamping groove, and therefore the limiting effect of the square box and the filter screen plate body can be relieved; the filter screen plate body can be pulled out of the heating box by pulling the handle, so that the filter screen plate body can be detached without using additional tools, the operation is convenient and fast, and the cleaning work of the filter screen plate body by workers is facilitated.
