It should also be understood that terms defined in general dictionaries should be interpreted to have meanings consistent with their meanings in the context of the relevant technology, and should not be interpreted in an idealized or extremely formalized sense, unless specifically defined here.

[0038] Techniques, methods and devices known to those skilled in the relevant art can not be discussed in detail, but in appropriate cases, the techniques, methods and devices should be considered as part of the specification.

[0039] An automatic feeding device for a laboratory microtome, such as Figures 1 to 3As shown, including the positioning frame 2 connected with the microtome 1, the positioning frame 2 as the skeleton of the automatic feeding device for the laboratory microtome, used to connect at the feeding port 10 of the microtome 1, both play a role in connection, and provide support and guidance for other components of the automatic feeding device for the laboratory microtome.

[0040] Other components mainly include feeding pressure plate 3 and spring assembly 4, wherein the positioning frame 2 provides support for the feeding pressure plate 3 and the spring assembly 4, and provides guidance for the up-down movement of the feeding pressure plate 3. The feeding pressure plate 3 under the extrusion of the spring assembly 4, under the guidance of the positioning frame 2, is used to directly press the material to be cut to step further to the feeding port 10 of the microtome 1. It should be noted that the step action is adapted to the continuous slicing of the microtome 1, that is, the spring assembly 4 presses the material to be cut to step further to the feeding port 10 of the microtome 1 every time a slice is cut. The spring assembly 4 not only provides support for the feeding pressure plate 3 under the counterforce of the positioning frame 2, but more importantly, can adjust the pre-tightening force of the material to be cut according to different sizes or different textures of the material to be cut.

[0041] Specifically, the feeding pressure plate 3 opposite to the feeding port 10 of the microtome 1 is slidably arranged along the positioning frame 2, and the spring assembly 4 is arranged between the top of the feeding pressure plate 3 and the positioning frame 2. That is, the feeding pressure plate 3 is adapted to the feeding port 10, and can press the material to be cut to the last piece, and the feeding pressure plate 3 does not interfere with the cutter in the feeding port 10. Specifically, when the axial size of the feeding port 10 is very small and directly close to the cutter of the microtome 1, the feeding pressure plate 3 is designed by shape and size not to enter the feeding port 10, only the lower end of the material to be cut passes through the feeding port 10 to contact the cutter of the microtome 1, as introduced in the background section of the present application, the microtome currently used by the applicant is the above-mentioned microtome, therefore the present embodiment mainly provides the improved embodiment as shown in Figure 1 .

[0042] If the axial size of the feeding port 10 is larger, the feeding pressure plate 3 is designed by shape and size to enter the feeding port 10 together with the material to be cut, at this time, a limiting structure is arranged at the upper end of the feeding pressure plate 3 to stop cooperation with the outer edge of the upper end of the feeding port 10, and the spacing between the limiting structure and the lower end of the feeding pressure plate 3 is smaller than the length of the feeding port 10, thereby avoiding the interference between the lower end of the feeding pressure plate 3 and the cutter of the microtome 1. Since the applicant does not use such a microtome at present, the present embodiment only provides a simple introduction of the corresponding technical solution for the possible technical problem, therefore the drawing is not shown.

[0043] Further, the spring assembly 4 comprises a spring cap 41 adjustably connected with the positioning frame 2, and a spring 42 is arranged in the spring cap 41 towards the top of the feeding platen 3, and the top of the feeding platen 3 is provided with a spring positioning seat 43 for plugging with the spring 42. The spring cap 41 is used for fixing the upper end of the spring 42, and the relative position between the spring cap 41 and the positioning frame 2 can be changed to adjust the pre-tightening force of the spring 42, and the spring positioning seat 43 is used for fixing the lower end of the spring 42.

[0044] On the basis of the above-mentioned embodiments, as a preferred embodiment of the automatic feeding device for the laboratory microtome, the positioning frame 2 comprises at least two upright columns 21, the bottom end of the upright column 21 is connected with the top surface 11 of the microtome 1 through an angle code 22, and the top end of the upright column 21 is connected through a cross beam 23. That is, the shape and structure of the positioning frame 2 can be various, for example, two upright columns 21 are combined with one cross beam 23 to form a door-shaped frame; for another example, three upright columns 21 are distributed at equal angles and combined with a Y-shaped cross beam 23 to form a more three-dimensional frame, and the like.

[0045] Among them, for the connection relationship between the upright column 21 and the top surface 11 of the microtome 1, the angle code 22 is only a convenient connection mode, that is, the vertical part of the angle code 22 is connected with the upright column 21, and the horizontal part of the angle code 22 is connected with the top surface 11 of the microtome 1. In addition, the upright column 21 can also be directly fixed on the top surface 11 of the microtome 1 through the thread at the lower end, and can also be connected with the top surface 11 of the microtome 1 through a clamping structure. As for the specific fixing mode, there are also various choices, such as screw connection, welding, plug-in connection and the like, and the person skilled in the art can select a suitable connection mode according to the actual needs.

[0046] On the basis of the above-mentioned embodiments, as a preferred embodiment of the automatic feeding device for the laboratory microtome, the cross beam 23 is provided with a threaded hole 231 penetrating up and down, the outer periphery of the spring cap 41 is provided with an external thread, and the spring cap 41 is connected with the threaded hole 231 of the cross beam 23 through the external thread. This embodiment provides a preferred structure design for the adjustable connection between the spring assembly 4 and the positioning frame 2, that is, the spring cap 41 is connected with the threaded hole 231 on the cross beam 23, and the length of the spring cap 41 can be set to one fourth of the length of the spring 42, so that the spring cap 41 has sufficient adjustment amount, and at the same time can provide sufficient positioning support for the spring 42.

[0047] On the basis of the above embodiment, as a preferred embodiment of the automatic feeding device for the laboratory microtome, a guide hole 31 is arranged on the feeding platen 3, and the guide hole 31 is in sliding fit with the stand column 21. This embodiment provides a preferred guide structure design when the feeding platen 3 moves up and down, that is, the stand column 21 of the positioning frame 2 is used as a guide column, and a corresponding guide hole 31 is directly arranged on the feeding platen 3. This not only has a simple structure and is convenient for manufacturing and assembling, but also realizes the guide by using the structure itself, so that the structure is compact and has better stability.

[0048] As another preferred embodiment of the automatic feeding device for the laboratory microtome, a guide groove is arranged on the outer edge of the feeding platen 3 in pairs with the stand column 21, and the guide groove is in sliding fit with the stand column 21. The guide structure design provided by this embodiment is simpler, and a hole does not need to be arranged on the feeding platen 3, but only a guide groove needs to be arranged.

[0049] On the basis of the above embodiment, as a preferred embodiment of the automatic feeding device for the laboratory microtome, a pull handle 33 is arranged through the cross beam 23, and the pull handle 33 is connected with the feeding platen 3. This embodiment provides a structure design convenient for operation. Since the space between the feeding platen 3 and the feeding port 10 of the microtome 1 is limited, if the operator directly pulls the feeding platen 3 upward by hand, the operator needs to coordinate the placement of the material to be cut at the same time, so that the operation is difficult. However, the pull handle 33 is used to pull the feeding platen 3 below the cross beam 23 from above, which is very fast, and there is no problem of interference with the placement of the material to be cut.

[0050] On the basis of the above embodiment, as a preferred embodiment of the automatic feeding device for the laboratory microtome, the pull handle 33 includes two pull columns 331 in penetrating fit with the cross beam 23, the two pull columns 331 are symmetrical about the spring cap 41, the upper ends of the two pull columns 331 are connected through a pull beam 332, and the lower ends of the two pull columns 331 are connected with the feeding platen 3.

[0051] On the basis of the above embodiment, as a preferred embodiment of the automatic feeding device for the laboratory microtome, the stand column 21 is connected to the top surface 11 of the microtome 1 through an angle code 22, a protruding pressing part 30 is arranged on the lower end surface of the feeding platen 3, and a sink 13 between the feeding port 10 and the top surface 11 is matched with the pressing part 30. This not only ensures that the feeding platen 3 is pressed in place, but also avoids that the feeding platen 3 enters the feeding port 10 and interferes with the cutter of the microtome 1.

[0052] On the basis of the above-mentioned embodiments, as a preferred embodiment of the automatic feeding device for the laboratory microtome, two sides of the spring assembly 4 are provided with auxiliary springs 44 which are symmetrical to each other, the auxiliary springs 44 are sleeved outside the lifting column 331 and the upper end is connected with the cross beam 23 and the lower end is connected with the feeding pressure plate 3, which further improves the reliability of automatic feeding.

[0055] The above shows and describes the basic principle, main features and beneficial effects of the present application. The above is only a preferred embodiment of the present application and does not limit the present application.
