Description

Technical Field

[0001] The present invention relates to the technical field of medical equipment, in particular to an automatic smear machine. Background Art

[0002] An automatic smear machine is a medical device that is mainly used to prepare cytological smears, that is, to automatically and evenly spread cell samples on a slide for subsequent microscopic examination and diagnosis. This equipment greatly improves the efficiency and quality of sample preparation through automated operation and reduces human errors.

[0003] However, in actual operation, due to the different smear sample preparation process, the thickness and size of the paint coating required for different smears are different; thus, in actual work, it is necessary to manually adjust the paint tube diameter of the automatic coating machine to meet different paint coating requirements through different sizes of paint tube diameters.

[0004] Therefore, in order to improve work efficiency, we propose an automatic coating machine which can achieve different coating requirements. Summary of the invention

[0005] In view of the defects in the prior art, the present invention provides an automatic smearing machine to achieve different coating size requirements of smears.

[0006] In the first aspect, the present invention provides an automatic coating machine, comprising: a coating machine body; a coating assembly, the coating assembly is installed on the coating machine body, and the coating assembly is driven to work by the coating machine body; the coating assembly includes a main coating tube, one end of the main coating tube is connected to the coating machine body, and the other end of the main coating tube is connected to the sheet to be coated; and a rotary sprayer, the rotary sprayer is installed in the coating assembly and is located in the main coating tube, wherein the rotary sprayer includes a fixed ring block, a driving member and a rotating ring block; the fixed ring block is provided with a mounting ring groove, the driving member is installed in the mounting ring groove, and the rotating ring block is rotatably installed in the fixed ring block; the driving member includes no less than three electromagnetic blocks, the electromagnetic blocks are evenly arranged in the mounting ring groove, and the electromagnetic blocks are connected to an external power supply, and are magnetically connected to the rotating ring block, and drive the rotating ring block to rotate; wherein the three electromagnetic blocks are energized at intervals, and only one electromagnetic block is energized at any time.

[0007] Furthermore, the rotating ring block includes a main ring body and a mounting block, the main ring body is provided with a fixing groove, the mounting block is mounted on the fixing groove, and the mounting block is magnetically connected to the electromagnetic block. In actual use, the main ring body in this design is made of non-magnetic material, among which plastic material is used. In this way, it can be ensured that the mounting block is independently subjected to the magnetic attraction force. In this way, the mounting block can drive the main ring body to rotate under the magnetic attraction drive of the electromagnetic block, thereby realizing the overall rotation of the rotating ring block. In this way, the paint fluid connected through the main paint pipe can be rotated and sprayed out.

[0008] Furthermore, the rotating ring block also includes a stabilizing block, the main ring body is provided with a stabilizing groove; the stabilizing block is installed in the stabilizing groove; the weight of the stabilizing block is the same as the weight of the mounting block, and the stabilizing groove is arranged at a relative position to the fixing groove and is level with the fixing groove. In actual use, the purpose of this design is to ensure that the rotating ring block can remain level when rotating and reduce its deflection; in this way, the speed can be controlled to effectively control the range of the paint spraying through the rotating ring block.

[0009] Furthermore, the coating assembly also includes a reducing pipe, which is installed on the main coating pipe and communicates with the main coating pipe. In actual use, the purpose of this design is to achieve effective diameter change, so that the coating width and thickness of the coating can be changed, so that the scope of application can be improved, and the manual tube replacement method previously used can be avoided, which is similar to the function of changing a knife, so that costs can be greatly saved and overall work efficiency can be improved.

[0010] Furthermore, the reducer pipe includes no less than three connected tapered sleeves, wherein the diameters of the connected tapered sleeves along the direction close to the main coating pipe decrease in sequence. In actual use, the connecting tapered sleeves in this design have different sizes, and the arithmetic difference decreasing method of the diameters can effectively maintain the connection, and also facilitate the subsequent realization of the diameter-changing function.

[0011] Furthermore, the connecting conical sleeve is also provided with an abutting outer platform and an abutting inner platform, wherein the abutting outer platform is provided at one end of the connecting conical sleeve, and the abutting inner platform is provided at the other end of the connecting conical sleeve, wherein any two adjacent connecting conical sleeves are connected via the abutting outer platform and the abutting inner platform. In actual use, the purpose of this design is to facilitate the connection of any two adjacent connecting conical sleeves, so that the three connecting conical sleeves connected in sequence can be effectively connected and communicated.

[0012] Furthermore, the coating component also includes a magnetic suction component, and the magnetic suction component includes a fixed mounting ring plate and an electromagnetic ring block. The electromagnetic ring block is provided with two pieces, and the fixed mounting ring plate is fixedly mounted on the coating machine body and covers the main coating tube; wherein the two electromagnetic ring blocks are mounted on the fixed mounting ring plate and are arranged horizontally opposite to each other. In actual use, the purpose of this design is to realize the control of the stretching and recovery of the above-mentioned connecting conical sleeve. When the connecting conical sleeve is stretched, the coating can only pass through the connecting conical sleeve in turn, and the size of the coating discharged at last is the smallest, which is convenient for small coating. When the conical sleeve is recovered, the coating is discharged directly without passing through in turn. In this way, the size of the coating discharged is larger. In this way, the coating discharge is large, and a larger range of coating coating can be performed. In this way, the coating size is changed without replacing the coating tube.

[0013] Furthermore, the connecting conical sleeve includes a main pipe body and a metal ring sleeve, wherein the main pipe body is covered outside the metal ring sleeve; and the metal ring sleeve is magnetically connected to the electromagnetic ring block. In actual use, the main pipe body is made of non-magnetic material, and is actually made of plastic material, while the metal ring sleeve is magnetically connected to the electromagnetic ring block, wherein the magnetic attraction force generated when the electromagnetic ring block is energized at the same time will be magnetically connected to the metal ring sleeve, so that the connecting conical sleeve is driven by the internal metal ring sleeve to achieve upward movement; and when the magnetism of the electromagnetic ring block disappears, the connecting conical sleeve falls downward under the weight of the metal ring sleeve inside it until it is stretched. In order to facilitate the adjustment of deflection, the electromagnetic ring block used can be energized on one side, so that when the metal ring in the connecting conical sleeve is subjected to magnetic attraction on one side, it can deflect and adjust; then the electromagnetic ring block at that location is powered off, and the electromagnetic ring block on the other side is powered on, so that the connecting conical sleeve can move to the other side. In this way, by shaking the connecting conical sleeve left and right, the material can be discharged. In this way, before the coating work, the paint can be avoided from accumulating in the connecting conical sleeve and affecting the discharging effect. In addition, when the two electromagnetic ring blocks are energized at intervals, the shaking effect can be effectively accelerated.

[0014] It can be seen from the above technical solution that the automatic smear machine provided by the present invention has the following beneficial effects:

[0015] (1) In actual use, the main coating tube in the coating assembly used in the design serves to communicate with the smear machine body, and the smear machine body is used to make cytological smears;

[0016] (2) The rotary sprayer arranged in the main coating tube can effectively spray the coating passing therethrough evenly, so that the coating process can be controlled; thus, manual intervention can be reduced, work efficiency can be improved, and different coating requirements can be effectively met;

[0017] (3) At the same time, the driving member is provided with no less than three electromagnetic blocks, which can effectively drive the rotation of the rotating ring block by controlling the power-on sequence and duration of the electromagnetic blocks; thereby, the installation area requirements are greatly reduced, making the structure of the overall component more compact and more integrated.
