This invention discloses a raw cotton impurity separation device, relating to the field of raw cotton impurity separation technology. The device includes a body, with a material cylinder fixed to its upper end. An inlet pipe is fixed to the upper end of one side of the material cylinder, and a chip removal pipe is fixed to the lower end of one side of the material cylinder. Several cotton inlets are opened through the lower end of the material cylinder, and these inlets are evenly distributed in an array. The interior of the material cylinder is interconnected through these cotton inlets. In the material-pulling structure of this invention, each pulling component corresponds to a cotton inlet. When the pulling spikes in the pulling component enter the material cylinder through the cotton inlets, the bevel gear at the end of the pulling spike engages with the bevel ring of the fixed unit, thereby converting the rotational motion of the pulling roller into the rotational motion of the pulling spikes. The friction and pulling force generated by the rotation pull the raw cotton out of the mixture. Due to the rotational motion of the pulling spikes, impurities are less likely to adhere to the pulling spikes or be pulled out along with the raw cotton, thus improving the impurity separation efficiency.

This invention belongs to the technical field of automotive sub-instrument panel assembly processing, specifically relating to a rapid changeover processing device for automotive sub-instrument panel assemblies. The device includes a laser welding apparatus and a rapid changeover fixture. The rapid changeover fixture comprises a fixture base, a mounting block, a threaded plate, and a screw. The mounting block is slidably connected to the upper part of the fixture base. The threaded plate is fixedly installed below the fixture base and has threaded holes on its surface. The screw is threaded into the threaded holes and has two limiting blocks at its upper end. A mounting cavity is slidably connected inside the mounting block, with the two limiting blocks located on the upper and lower sides of the mounting cavity, respectively. This device solves the problem that current processing of automotive sub-instrument panel assemblies requires multiple processing devices for multiple models, significantly increasing costs. Furthermore, the processing devices used cannot achieve rapid changeover, leading to reduced production efficiency and negatively impacting the assembly's production quality.

The utility model provides a novel passenger car vulcanized steel plate spring assembly which comprises a plurality of plate spring pieces and a fixing mechanism which are sequentially arranged in a laminated mode from top to bottom, abrasion-resistant rubber layers are vulcanized on the surfaces of the plate spring pieces, the fixing mechanism comprises a center bolt assembly and a clamp assembly, and the center bolt assembly comprises a center bolt and a fastening nut. Bolt through holes are formed in the multiple plate spring pieces, and the center bolt sequentially penetrates through the bolt through holes in the multiple plate spring pieces and then is connected with the fastening nut. The clamping hoop assembly comprises clamping hoop pieces arranged on the two sides of the multiple plate spring pieces, and wear-resisting rubber layers are vulcanized on the inner sides of the clamping hoop pieces. According to the novel passenger car vulcanized steel plate spring assembly, contact collision between the plate spring pieces and contact collision between the plate spring pieces and the clamp pieces in the vehicle running process can be avoided, so that noise and contact abrasion between the plate spring pieces and between the plate spring pieces and the clamp pieces are eliminated, the vehicle driving and riding comfort is effectively improved, the fatigue life of the steel plate springs is prolonged, and the service life of the steel plate springs is prolonged. The maintenance and use cost of the steel plate spring is reduced.

The utility model belongs to the field of geological exploration sampling, and particularly relates to a stabilizing mechanism for a geological exploration sampling device, which comprises an outer cylinder, a connecting rod is slidably connected to an inner cavity of the outer cylinder, a connecting plate is fixedly connected to one end of the connecting rod, and a supporting structure is arranged at the other end of the connecting rod; the extension plates and the transmission gear are integrally formed, the transmission gear and the extension plates are rotationally connected to the inner cavity of the support, when the extension plates are combined, a drill bit of the sampling device body in the inner cavity of the lifting cylinder can be protected, and the lifting cylinder can lift and slide along the inner cavity of the outer cylinder; as the tooth surface of the transmission gear abuts against one side of the transmission plate to form a meshing state, when the transmission cylinder descends, the transmission gear can be driven to drive the extension plate to synchronously rotate and unfold to form a supporting leg, and a bottom plate at the other end of the extension plate makes contact with the ground and can be fixedly connected with the ground by adopting a ground bolt to penetrate through an insertion hole. The effects of being portable and protecting the drill bit of the sampling device are achieved.

The present application relates to concrete pouring forming equipment technical field, disclose a kind of pouring forming equipment and the forming method for concrete prefabricated part processing, including rack, portal, suspension roller shaft and pipe making mould, the rack and portal are arranged in parallel, and the distance between rack and portal is fixed;The pouring forming equipment, by setting control shaft sleeve, rotary drive mechanism and shaft rod translation mechanism, so that the height and inclination angle of suspension roller cannot be changed while having rotation and linear movement function, so that after lifting pipe making mould, can first let the suspension roller shaft that cannot shake greatly be extracted from pipe making mould inside, to avoid when moving out pipe making mould, suspension roller shaft and cement pipe inner wall contact collision, simultaneously, by setting shaft rod cleaning mechanism, under the cooperation of rotary drive mechanism, in the process that suspension roller shaft is away from portal, surface will be wiped by cleaning brush plate, to avoid that concrete is adhered on the surface of suspension roller shaft.

This utility model belongs to the field of medical product recycling technology, and particularly relates to a storage box for infectious disease nursing instruments. It includes a storage box shell with an internal telescopic cavity. Multiple storage components are fixedly connected to the bottom of the telescopic cavity. Each storage component includes a supporting base plate, and a telescopic assembly is fixedly connected to the upper surface of the supporting base plate. The telescopic assembly includes a fixed plate with a sliding groove on its upper surface. A rotating wheel is rotatably connected inside the sliding groove, and a supporting plate is fixedly connected to the upper end of the rotating wheel. A storage box is fixedly connected to the upper end of the supporting plate. This infectious disease nursing instrument storage box, by rotating the drive end, causes a transmission column to drive a gear to mesh with a gear block, moving two supporting plates in opposite directions and causing the storage box to extend outwards. This allows instruments to be placed inside the storage box, reducing the area for disinfection and effectively preventing contact with the storage box.
