[0002] The utility model also relates to a labeling machine. Background Art

[0003] At present, when hospitals conduct blood collection and testing, blood collection tubes are often used. In order to facilitate information alignment, labels are generally pasted on the outer wall of the blood collection tubes. Blood collection tubes can be divided into multiple types according to whether they contain additives and the types of additives, and are distinguished by different colors of tube caps. When hospitals conduct blood tests on patients, each patient often needs to undergo multiple tests. Different tests require the use of different types of blood collection tubes, and patient labels need to be pasted on the blood collection tubes before blood collection. This work is extremely cumbersome and labor-intensive. Relying solely on manual operation is time-consuming and laborious, and sometimes accidents such as selecting the wrong type of blood collection tube or missing or mislabeling patient labels may occur. For this reason, some hospitals use blood collection tube labeling machines to replace manual operation.

[0004] The labeling of blood collection tubes is mainly completed by driving the rotation of a rubber roller. After the blood collection tube is labeled and drops off for normal blood collection, the rubber roller in contact with the label will adhere to the back glue during use. When the back glue accumulates, the blood collection tube will adhere to it, and it cannot drop off normally, resulting in the machine malfunctioning and shutting down. Content of the Utility Model

[0030] Embodiment 1

[0031] As Figure 1 and Figure 2 shown, a rubber roller mechanism convenient for cleaning includes a main support shaft 901, a fixed thimble 902, a rubber roller spring 903, a rubber roller rubber 904, a main support shaft seal 905 and a main support shaft thimble 906;

[0032] The main support shaft 901 is vertically arranged. There is a hollow channel inside the main support shaft 901. A rubber roller spring 903 is installed in the hollow channel of the main support shaft 901. A fixed thimble 902 with its top inserted into one end of the hollow channel is installed at the bottom end of the main support shaft 901. The top end of the fixed thimble 902 abuts against the bottom end of the rubber roller spring 903;

[0033] A main support shaft seal 905 is installed at the top end of the main support shaft 901. The main support shaft seal 905 is sleeved outside the main support shaft thimble 906. The bottom end of the main support shaft thimble 906 is inserted into the other end of the hollow channel. The bottom end of the main support shaft thimble 906 abuts against the top end of the rubber roller spring 903. The main support shaft seal 905 is used to limit the vertical movement distance of the main support shaft thimble 906 to prevent the bottom end of the main support shaft thimble 906 from detaching from the hollow channel. A rubber roller rubber 904 is arranged outside the main support shaft 901.

[0034] In this embodiment, the rubber roller mechanism 9 has a simple structure and is convenient for installation and use. During installation, the fixed thimble 902 and the main support shaft thimble 906 on the rubber roller mechanism 9 are inserted into the through holes or installed on the machine through bearings. When there is too much back glue adhered to the rubber roller mechanism 9 and it needs to be cleaned, by pressing down the main support shaft thimble 906, the rubber roller spring 903 contracts, the main support shaft thimble 906 moves downward and disconnects from the installation part, and then the rubber roller mechanism 9 is removed. The rubber roller mechanism 9 is cleaned accordingly to remove the adhered back glue, and then the cleaned rubber roller mechanism 9 is installed back on the machine. The rubber roller mechanism 9 provided in this embodiment is convenient for disassembly and cleaning.

[0035] The outer diameter of the top end and the bottom end of the main support shaft thimble 906 is larger than the outer diameter of the middle part of the main support shaft thimble 906. A main support shaft seal 905 is sleeved outside the middle part of the main support shaft thimble 906. The inner diameter of the main support shaft seal 905 is larger than the outer diameter of the middle part of the main support shaft 901, and the inner diameter of the main support shaft seal 905 is smaller than the outer diameter of the top end and the bottom end of the main support shaft 901. The main support shaft seal 905 is used to limit the movement distance of the main support shaft thimble 906.

[0036] In this embodiment, the main support shaft seal 905 is used to limit the moving distance of the main support shaft thimble 906, preventing the main support shaft thimble 906 from detaching from the hollow channel inside the main support shaft 901 or being fully inserted into the hollow channel, which may cause the problem that the rubber roller mechanism 9 becomes inoperable.

[0037] Embodiment 2

[0038] As Figures 1 - 8 shown, a labeling machine includes a rubber roller mechanism 9 as shown in Embodiment 1, and further includes a mounting plate 1, a driving rubber roller fastener 4, a clamping mechanism 7, a manipulator clamp 2, and a labeling printer 8.

[0039] The driving rubber roller fastener 4, the clamping mechanism 7, and the labeling printer 8 are mounted on the top of the mounting plate 1;

[0040] An opening is provided on the mounting plate 1 between the driving rubber roller fastener 4 and the clamping mechanism 7, and a collection trough 10 is provided at intervals below the opening;

[0041] A vertically arranged driving rubber roller 6 is rotatably connected to the driving rubber roller fastener 4; two rubber roller mechanisms 9 are rotatably connected to the clamping mechanism 7; the manipulator clamp 2 is used to move the test tube 3; the clamping mechanism 7 is slidably connected to the top of the mounting plate 1 and can move closer to or away from the driving rubber roller fastener 4. The rubber roller mechanism 9 is used to cooperate with the driving rubber roller 6 to clamp and rotate the test tube 3. The bottom of the driving rubber roller 6 passes through the mounting plate 1 and is connected with a gear, and the driving rubber roller 6 is rotated by driving the gear to rotate; the manipulator clamp 2 and the labeling printer 8 are prior arts and will not be elaborated here.

[0042] In this embodiment, the manipulator clamp 2 is used to clamp the test tube 3 and then move the test tube 3 between the driving rubber roller fastener 4 and the clamping mechanism 7. Subsequently, the manipulator clamp 2 releases the test tube 3, and the test tube 3 drops downward; the clamping mechanism 7 moves towards the driving rubber roller fastener 4, and the two rubber roller mechanisms 9 cooperate with the driving rubber roller 6 to clamp the test tube 3; by driving the gear at the bottom of the driving rubber roller 6 to rotate, the test tube 3 and the two rubber roller mechanisms 9 are driven to rotate. The labeling printer 8 sends the label to the wall of the test tube 3 for pasting. As the test tube 3 rotates, the label pasting is completed. Subsequently, the clamping mechanism 7 moves away from the driving rubber roller fastener 4, and the test tube 3 moves downward and passes through the opening on the mounting plate 1 and falls into the collection trough 10 below the mounting plate 1.

[0043] A test tube inductor 5 is provided on one side of the driving rubber roller fastener 4. The test tube inductor 5 is used to transmit signals to a control device (not shown in the figure) and control the operation of the clamping mechanism 7 through the control device; the control device is a prior art and will not be elaborated here.

[0044] In this embodiment, the test tube sensor 5 is used to sense the position of the test tube 3. After the test tube sensor 5 senses the test tube 3, the clamping mechanism 7 quickly moves towards the driving rubber roller fastener 4, and clamps the test tube 3 through the driving rubber roller 6 and the rubber roller mechanism 9.

[0045] The clamping mechanism 7 includes a connecting member 701. At the top of one side surface of the connecting member 701, there is a test tube labeling duckbill 702; at the bottom of the connecting member 701, there is a slider 703. On the top surface of the mounting plate 1, there is a slide rail 704, and the slider 703 is slidably connected to the slide rail 704; at the top of the connecting member 701, there is a push rod electromagnet 705, and the push rod electromagnet 705 is used to control the movement of the connecting member 701 along the slide rail 704; the push rod electromagnet 705 is a prior art and will not be elaborated here.

[0046] In this embodiment, when the clamping mechanism 7 moves towards the driving rubber roller fastener 4, the test tube labeling duckbill 702 cooperates with the arc groove provided at the top of the driving rubber roller fastener 4 to clamp the test tube 3 to prevent the test tube 3 from falling downward; after the label is pasted, the clamping mechanism 7 moves away from the direction of the driving rubber roller 6 clamping member, and the test tube labeling duckbill 702 releases the test tube 3.

[0047] On one side of the connecting member 701, there is a rubber roller mechanism 9. The top end of the rubber roller mechanism 9 is inserted into the through hole provided on the test tube labeling duckbill 702 and is rotatably connected to the test tube edge labeling duckbill 702; the bottom end of the rubber roller mechanism 9 is inserted into the through hole provided at the bottom of the connecting member 701 and is rotatably connected to the connecting member 701.

[0048] Working principle: The manipulator clamp 2 transports the test tube 3 to the middle of the clamping mechanism 7 and the driving rubber roller fastener 4, and the manipulator clamp 2 releases the test tube 3, and the test tube 3 falls downward; the test tube sensor 5 senses the test tube 3 and transmits the signal to the control device that controls the operation of the clamping mechanism 7. The control device controls the push rod electromagnet 705 to push the connecting member 701 towards the driving rubber roller fastener 4. The test tube labeling duckbill 702 cooperates with the arc groove on the driving rubber roller fastener 4 to clamp the test tube 3, and the rubber roller mechanism 9 and the driving rubber roller 6 clamp the test tube 3; the driving rubber roller 6 rotates, and then drives the test tube 3 and the rubber roller mechanism 9 to rotate. The label printer 8 sends the label to the wall of the test tube 3 for pasting. As the test tube 3 rotates, the label pasting is completed. Then, the clamping mechanism 7 moves away from the driving rubber roller fastener 4, and the test tube 3 moves downward and passes through the opening on the mounting plate 1 and falls into the collection tank 10 located below the mounting plate 1.

[0049] When too much back glue adheres to the active rubber roller 6 on the rubber roller mechanism 9 and needs to be cleaned, by pressing down the main support shaft thimble 906, the main support shaft thimble 906 is disengaged from the through hole at the test tube labeling duckbill 702, and the rubber roller mechanism 9 can be simply and conveniently removed. Subsequently, corresponding cleaning is carried out to remove the back glue adhering to the rubber roller mechanism 9. After cleaning, press the main support shaft thimble 906 to install the rubber roller mechanism 9 back to its original position. Under the action of the rubber roller spring 903, the main support shaft thimble 906 is installed back to its original position.
