The invention discloses a device used for rat brain tissue slicing and layering. The device comprises a slicing module, wherein the slicing module is provided with a plurality of cutter grooves with equal spacing, and fresh rat brain tissues are placed on the slicing module in slicing operation. The device is characterized in that the slicing module is embedded in a rectangular cavity on an operation desk, a cutter with a tool rest is arranged above the slicing module, two blades which are mutually parallel and vertical downwards are arranged below the tool rest, spacing between the two blades is just equal to distance between two cutter grooves of the slicing module, the cutter is connected with the upper end of a vertical arm, and the lower end of the vertical arm is connected with a mechanism which can move along the front length direction of the operation desk for positioning.

The invention discloses a shaping device for extruding and slicing tobacco leaves. The invention comprises a frame, an inlet and an outlet respectively arranged on the upper and lower sides of the frame, and are arranged on the frame to roll against each other to shape the tobacco leaves. The driving cutting roller and the driven light roller of the slice, the driving motor for driving the driven smooth roller and the driving cutting roller to roll the slice, and the driving motor fixed on the frame and positioned above the driving cutting roller for blowing down The gas stripping tube from the drop-shaped tobacco leaves to the discharge port; the active cutting roller includes a forming part on its surface for pressing and forming the tobacco leaves and a positive part arranged hollow along its central axis for feeding compressed air. A pressure part, an air source element for providing an air source, and a plurality of communication pipes connected between the positive pressure part and the forming part for releasing pressure to the forming part to separate the shaped tobacco leaves from the forming part.

The invention discloses a monocrystalline silicon rod slicing device, the structure of which comprises a distribution box, a cutting head, an introduction device, a processing table, a fixing seat, and a base. The head is matched with the introduction device, and the beneficial effect of the present invention is that when the sandwich layer on the clamp head is in contact with the monocrystalline silicon rod, the magnetic properties of the two magnetic blocks are different, and the mutual attraction strengthens the clamping force of the clamp head , under the double function, the clamping head can clamp and fix the single crystal silicon rod, and the two movable grooves can be pushed out and replaced according to the diameter of the single crystal silicon rod and adapted to the size of the single crystal silicon rod. When the first movable slot and the two fixed slots are on the same arc, stop the outward movement, and at the same time apply force to the single crystal silicon rod, so that the single crystal silicon rod is fixed, thereby preventing the single crystal silicon rod from being impacted by the wire saw. Displacement occurs to ensure that the position of the single crystal silicon rod is relatively fixed during processing, and further guarantees the slice quality of the single crystal silicon rod.

The invention relates to the technical field of pathological slicing equipment, and more particularly, to a sliding type large slicer, comprising: a slicing table, a slicing knife mechanism, a slicing control mechanism, a fixed limit mechanism and a push limit mechanism; The control mechanism is matched and connected to the slicing table; the slicing control mechanism is matched and connected with the slicing knife mechanism to drive the slicing knife mechanism to slice the pathological samples placed on the slicing table; the fixing The limit mechanism and the push limit mechanism are relatively matched on the slicing table to limit and fix the pathological sample; the slice knife mechanism is matched with the fixed limit mechanism and the push limit mechanism between. The invention is convenient for cutting pathological samples into pathological slices with clear tissue structure, which is helpful for preserving the complete morphological structure of the pathological slice tissue, and is beneficial to accurate pathological diagnosis.

The invention discloses a multi-wire cutting machine guide wheel wire groove and a machining method of the multi-wire cutting machine guide wheel wire groove. A left straight side portion and a right straight side portion are formed by a multi-wire cutting machine guide wheel on the basis of each traditional V-shaped groove, wherein each left straight side portion and each right straight side portion are parallel to the center line of one wire groove. According to the structure, the axial width of each V-shaped groove is reduced, even under the action of the axial acting force F, the cutting steel wire is prevented from generating transitional axial deviation, and therefore the defects of line marks, steps and the like generated on the surface of a crystal slice are reduced. In addition, the cutting steel wire is completely contained in each wire groove through one left straight side portion and one right straight side portion located at the two sides of one V-shaped groove. A component force FS, generated on the side wall of each V-shaped wire groove, of the axial acting force F is weakened due to the fact that the component force FS is restrained by the extrusion force of one left straight side portion or one right straight side portion, so that the difficulty for the cutting steel wire to move towards each groove top is increased, the wire jumping accident of the cutting steel wire is avoided, and therefore the slice quality of the crystal slice in the whole process of production is guaranteed.
