[0027] Specific operation as follows, paraffin block is placed in the lifting plate 2 inside, by rotating the threaded rod 3 so that the clamping plate 4 along the lifting plate 2 surface sliding, so that the lifting plate 2 cooperate lifting plate 2 to paraffin block clamped, and the end face of paraffin block protruding from the clamping plate 4, lifting plate 2 end face in order to accept the section, and lifting plate 2 through the section machine body 1 inside the drive source such as motor screw or electric push rod lifting movement, in the lifting plate 2 down, spring telescopic rod piston 509 itself first from the contraction state downward, when it extends to the limit because of the lifting plate 2 continue to drop down the spring telescopic rod piston 509 as a whole, at this time the first one-way valve 502 open while the second one-way valve 504 closed, so that the water tank in the flow medium along the first transmission pipe 503 into the transfer cylinder 501 inside, while the lifting plate 2 carrying paraffin block lifting, spring telescopic rod piston 509 itself first from the extension state to the contraction state, when the contraction to the limit spring telescopic rod piston 509 as a whole, at this time the first one-way valve 502 closed while the second one-way valve 504 open, at this time the transfer cylinder 501 inside the flow medium along the second transmission pipe 505 into the transmission box 506 inside, so that the telescopic piston 507 carrying blade base 508 extension, thus the blade body 605 fixed distance close to paraffin block, constantly repeat the above operation, because the blade body 605 each time the distance is fixed so that the paraffin block can be evenly cut into several pieces of thin slice;

[0028] Among them, the transfer cylinder 501 inside injection or discharge flow medium, is in the spring telescopic rod piston 509 itself completely extended or completely retracted, such as paraffin block lifting height exceeds the blade body 605 height after the spring telescopic rod piston 509 itself completely retracted, and then the flow medium is injected into the transmission box 506 inside, at this time the blade body 605 just extended, thus avoid paraffin block from the bottom up the blade body 605 is extended from the paraffin block movement with the extension of the conflict;

[0029] After the section, pipe valve 510 open, so that the transmission box 506 inside the flow medium through the backflow pipe 511 to the water tank inside, at this time the telescopic piston 507, blade base 508 carrying blade body 605 natural contraction reset, in order to use next time;

[0030] Based on the above description, the present application uses the principle that the lifting plate 2 clamps the paraffin block to carry out repeated lifting motion, injects a quantitative flowing medium into the inside of the transfer cylinder 501 when descending each time, and injects the flowing medium in the inside of the transfer cylinder 501 into the inside of the transmission box 506 when the paraffin block rises, so that the blade body 605 is adapted to the overhanging fixed distance of the paraffin block with each lifting, thereby realizing the rapid slicing of the paraffin block while ensuring the uniformity of each slice, and using the elastic expansion and contraction effect of the spring expansion rod piston 509, the blade body 605 will produce a delay effect when moving each time with the lifting of the lifting plate 2, so as to avoid the paraffin block from rising from the bottom, and the blade body 605 will be stretched out to interfere with the movement of the paraffin block.

[0031] As shown in Figures 1-5 The surface of the blade base 508 is fixed with a blade assembly 6, the blade assembly 6 comprises a driving motor 601, a rotating lead screw 602 and a moving sleeve base 603, the output end of the driving motor 601 is connected with the rotating lead screw 602, the outer wall of the rotating lead screw 602 is sleeved with the moving sleeve base 603, the end of the rotating lead screw 602 away from the driving motor 601 is rotationally connected with the blade base 508, and the rotating lead screw 602 is arranged in a horizontal state, the blade assembly 6 further comprises a blade fixed seat 604, the moving sleeve base 603 is sleeved with the blade fixed seat 604, the blade fixed seat 604 is arranged in an inclined state, and the blade fixed seat 604 is slidably connected with the blade base 508, the blade assembly 6 further comprises a blade body 605, the blade fixed seat 604 is inserted with the blade body 605, the blade assembly 6 further comprises a spacing strip 606, the surface of the blade body 605 is equidistantly distributed with the spacing strip 606, the bottom end of the spacing strip 606 is fixedly connected with the surface of the blade fixed seat 604, and the top of the spacing strip 606 is located at the cutting edge of the blade body 605;

[0032] The specific operation is as follows: when the blade base 508 carries the blade body 605 to move each time, the displacement sensor inside the blade base 508 senses the movement, drives the rotating lead screw 602 to rotate to make the moving sleeve base 603 on the surface of the rotating lead screw 602 carry the blade fixing seat 604 and the blade body 605 to translate a preset distance, and the preset distance is the interval between two adjacent spacing strips 606. The spacing strips 606 divide the surface of the blade body 605 into a plurality of slice areas. After one slice area has already sliced the paraffin block, the rotating lead screw 602 is driven by the driving motor 601 to rotate so that the blade body 605 moves, so that the next slice area of the blade body 605 replaces the used slice area, so that the same area is not used for slicing operation each time the blade body 605 slices the paraffin block, so as to prevent the risk of cross contamination of the sliced thin slices, and the spacing strips 606 separate each slice area to prevent the slice residues on the surface of each slice area from spreading, so that the blade body 605 does not need to be frequently replaced to ensure the cleanliness of each thin slice.

[0033] In summary, the pathological slice rapid preparation device with convenient operation is used. First, the paraffin block is placed on the inner side of the lifting plate 2. The clamping plate 4 is slid along the surface of the lifting plate 2 by rotating the threaded rod 3, so that the lifting plate 2 clamps the paraffin block in cooperation with the lifting plate 2. The lifting plate 2 is lifted and lowered by the driving source in the slicer body 1, such as a motor lead screw or an electric push rod. When the lifting plate 2 is lowered, the spring telescopic rod piston 509 itself first extends downward from the retracted state. When it extends to the limit, the spring telescopic rod piston 509 is lowered as a whole due to the continuous lowering of the lifting plate 2. At this time, the first one-way valve 502 is opened and the second one-way valve 504 is closed, so that the flow medium in the water tank is injected into the transfer cylinder 501 inside along the first transmission pipe 503. When the lifting plate 2 carrying the paraffin block is lifted, the spring telescopic rod piston 509 itself changes from the extended state to the retracted state. When it is retracted to the limit, the spring telescopic rod piston 509 is raised as a whole. At this time, the first one-way valve 502 is closed and the second one-way valve 504 is opened. At this time, the flow medium in the transfer cylinder 501 enters the transmission box 506 inside along the second transmission pipe 505, so that the telescopic piston 507 carries the blade base 508 to extend. Thus, the blade body 605 is fixedly close to the paraffin block. The above operation is repeatedly performed. Since the moving distance of the blade body 605 is fixed each time, the paraffin block can be uniformly cut into a plurality of thin slices;

[0034] Wherein when the flow medium is injected or discharged in the inside of the transfer cylinder 501, the spring telescopic rod piston 509 is fully stretched or fully retracted, and after the height of the paraffin block exceeds the height of the blade body 605, the spring telescopic rod piston 509 is fully retracted, and then the flow medium is injected into the inside of the transmission box 506, and at this time, the blade body 605 is stretched, thereby avoiding the interference and conflict between the movement of the paraffin block and the stretching of the blade body 605 from the bottom.

[0035] When the blade base 508 carries the blade body 605 to move each time, the displacement sensor in the inside of the blade base 508 senses the movement, drives the motor 601 to rotate the rotating lead screw 602 to make the moving sleeve base 603 on the surface of the rotating lead screw 602 carry the blade fixing seat 604 and the blade body 605 to translate a preset distance, and the preset distance is the interval between two adjacent interval strips 606, the interval strips 606 divide the surface of the blade body 605 into a plurality of slice areas, after a slice area has already sliced the paraffin block, the rotating lead screw 602 is driven by the motor 601 to rotate, so that the blade body 605 moves, thereby replacing the used slice area with the next slice area of the blade body 605, so that the same area is not used for slicing operation each time the paraffin block is sliced by the blade body 605.

[0036] The embodiments of the present application are given for illustration and description only, and are not exhaustive or limiting to the present application. Many modifications and variations will be apparent to those of ordinary skill in the art. The embodiments are chosen and described in order to best explain the principles of the application and its practical application, and to enable others skilled in the art to understand the application for various embodiments with various modifications as are suited to the particular use contemplated.
