Description

Technical Field

[0001] The present invention relates to the technical field of pathological tissue processing, and in particular to an immersion type automatic wax sealing machine for pathological tissue wax blocks. Background Art

[0002] Clinical pathological tissues are made into pathological tissue wax blocks after multiple processes. After the wax blocks are sliced and then subjected to staining, immunohistochemistry and other treatments, pathological information is provided for disease diagnosis. Thereafter, the wax blocks need to be wax-sealed due to medical norms and research requirements to isolate the contact and reaction between the tissues in the wax blocks and air, so as to maintain the pathological characteristics of the pathological tissues for a long time.

[0003] At present, the pure manual method is generally used for wax sealing after slicing of pathological tissue wax blocks. For example: using the embedding machine platform, pouring wax liquid on the plate to form a thin layer of wax liquid, and then gently pressing the pathological tissue wax block on the thin layer of wax liquid to form a wax sealing effect; using the embedding box preheating groove of the embedding machine, that is, holding the wax block to first make the pathological tissue surface contact with the wax liquid, and then gently sliding the same surface on the preheating groove platform for wax sealing; melting wax using tools such as rice cookers, laying the wax blocks flat, and then using a brush-like tool to dip wax liquid and quickly smear the pathological tissue block for wax sealing; using the wax sealing groove of some specific models of spreading and baking machines, injecting a small amount of molten wax liquid into the wax sealing groove, and putting each wax block into the wax sealing groove for wax sealing immediately after the slicing is completed.

[0004] The efficiency of such manual wax sealing methods is very low, and large-scale wax sealing operations cannot be carried out. Moreover, manual wax sealing not only cannot control the wax sealing thickness and the flatness of the wax surface, but may also cause the operator to inhale aerosolized wax liquid particles, which will have an adverse impact on health.

[0027] To describe in detail the technical content, achieved objectives, and effects of the present invention, the following is described in conjunction with the implementation mode and accompanied by the drawings.

[0028] Refer to the attached Figures 1 to 6 , an immersion type automatic wax sealing machine for pathological tissue wax blocks of the present invention includes a slot-type conveyor belt 1, a wax sedimentation tank 2, and a cooling device 3;

[0029] The slot-type conveyor belt 1 is disposed around the outer sides of the wax sedimentation tank 2 and the cooling device 3. A plurality of slots 11 penetrating through its surface are evenly formed on the surface of the slot-type conveyor belt 1. During the operation of the slot-type conveyor belt 1, the slots 11 sequentially pass above the wax sedimentation tank 2 and the cooling device 3.

[0030] The working principle of the present invention is as follows: The pathological tissue wax block is inserted into the slot 11 of the slot-type conveyor belt 1, and it is ensured that the side of the wax block where the pathological tissue is exposed (hereinafter referred to as the tissue side) faces downward. Subsequently, the slot-type conveyor belt 1 drives the wax block to pass above the wax sedimentation tank 2 under the drive of an external motor. At the same time, the tissue side of the wax block contacts the surface of the molten wax liquid in the lower wax sediment, so that the wax block is evenly coated with a layer of wax liquid. Finally, the wax block moves above the cooling device 3, and the cooling device 3 cools the wax liquid on the wax block to make the wax liquid solidify, thereby completing the wax sealing.

[0031] From the above description, it can be seen that the beneficial effects of the present invention are: the use of an immersed and automated wax sealing method greatly improves the wax sealing efficiency; by immersing the wax block in a wax settling tank for wax sealing, the smoothness of the wax block surface and the homogeneity of the quality of different wax blocks can be effectively guaranteed; after the wax block is waxed, the wax sealing surface is directly cooled by a cooling device to solidify it, thereby protecting the integrity of the wax block tissue surface during the wax sealing process; the automated wax sealing process can prevent operators from inhaling aerosol wax liquid particles.

[0032] Furthermore, a curved scraper 21 is provided on one side of the wax settling tank 2 close to the cooling device 3 .

[0033] As can be seen from the above description, the arc-shaped scraper can wipe off excess wax drops, thereby ensuring the smoothness of the wax sealing surface.

[0034] Furthermore, it also includes a material receiving platform 4 and a material guiding trough 5;

[0035] The receiving platform 4 is provided with a plurality of first wax block grooves 41 arranged in parallel, and a first pushing mechanism 42 is arranged in the wax block grooves. The receiving platform 4 is also provided with a first longitudinal groove 43 communicating with the first wax block grooves 41, and a first conveyor belt 44 is arranged at the bottom of the first longitudinal groove 43;

[0036] The material guide trough 5 is located between the material receiving platform 4 and the slot-type conveyor belt 1, and an entrance connected to the first longitudinal groove 43 is provided on one side of the material guide trough 5. An outlet is provided on the bottom of the material guide trough 5 close to the slot-type conveyor belt 1, and the outlet is located above the slot-type conveyor belt 1. A baffle plate 51 is provided on the top of the material guide trough 5, and the baffle plate 51 is located above the outlet. A toggle plate 52 is provided on the bottom of the material guide trough 5 away from the outlet.

[0037] As can be seen from the above description, multiple wax blocks can be stored in the first wax block groove, and the tissue surface of the wax block is perpendicular to the bottom surface of the first wax block groove, so that the tissue surface on the wax block and the bottom surface of the first wax block groove can be prevented from being squeezed and affecting the pathological tissue in the wax block. The pushing mechanism in the first longitudinal groove can push the wax block into the first longitudinal groove, and then the wax block is transported to the guide groove through the first conveyor belt. The toggle plate in the guide groove can push the wax block to the outlet under the drive of the internal motor. At the same time, since a baffle is provided on the top of the guide groove, when the wax block falls from the outlet into the card slot of the card slot type conveyor, the tissue surface of the wax block can automatically turn downward. A large number of wax blocks to be sealed with wax can be stored in the material receiving table at one time, so that there is no need to manually place the wax blocks on the card slot type conveyor belt repeatedly, further improving the wax sealing efficiency; the guide groove mainly plays the role of flipping the wax block, so that when the wax block is in the material receiving table, the tissue surface can be stored perpendicular to the horizontal plane, thereby avoiding squeezing and scratching between the tissue surface and the bottom surface of the material receiving table.

[0038] Further, telescopic clamping blocks 45 are provided on both sides of the first wax block groove 41.

[0039] As can be seen from the above description, the telescopic clamping blocks can ensure that only one wax block is pushed out of the first wax block groove each time.

[0040] Further, it further includes a collection table 7;

[0041] A plurality of second wax block grooves 71 arranged in parallel are formed on the collection table 7. A second longitudinal groove 72 communicating with the second wax block grooves 71 is also formed on the collection table 7. A second pushing mechanism 73 corresponding to the second wax block grooves 71 is provided on the side wall of the second longitudinal groove 72 away from the second wax block grooves 71. A second conveyor belt 74 is provided at the bottom of the second longitudinal groove 72.

[0042] As can be seen from the above description, after the wax block passes through the cooling device and moves to the end along the card slot conveyor belt, it will directly fall onto the second conveyor belt on the collection table. The second pushing mechanism can push the wax blocks into the second wax block grooves in sequence from the longitudinal groove for collection, and after the wax sealing is completed, the wax blocks can maintain the arrangement order and arrangement method when entering the machine, which is convenient for subsequent sorting and storage of the wax blocks.

[0043] Further, it further includes a temperature sensor and a heating device. The temperature sensor and the heating device are electrically connected, and both the temperature sensor and the heating device are fixedly connected to the wax settling tank 2.

[0044] Further, it further includes a wax storage tank 6 and a liquid level sensor. The wax storage tank 6 is communicated with the wax settling tank 2 through a switching valve. The liquid level sensor is fixedly connected to the wax settling tank 2, and the liquid level sensor is electrically connected to the switching valve of the wax storage tank 6.

[0045] As can be seen from the above description, the wax storage tank is filled with molten wax liquid. When the liquid level sensor senses that the liquid level in the wax settling tank is lower than the threshold value, the switching valve can be opened, so that the wax liquid in the wax storage tank flows into the wax settling tank for replenishment.

[0046] Further, the cooling device 3 is a cooling fan.
