In the description of this application, it should also be noted that, unless otherwise clearly specified and limited, the terms "installation" and "connection" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be directly connected or indirectly connected. For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to the specific circumstances.

[0032] Figure 1 A schematic structural diagram of a labeling and printing device for test tubes according to an embodiment of the present application is shown.

[0033] See also Figure 1 An embodiment of the present application provides a labeling and printing device for a test tube, comprising: a paper supply device 1, a printing device 2, a first clamping mechanism 3 and a second clamping mechanism 4.

[0034] The paper supply device 1 includes a paper supply bin 11 and a paper supply mechanism 12, a clamping assembly 13 and label paper 14 arranged in the paper supply bin 11. The paper supply bin 11 has a first opening 111. The paper supply mechanism 12 is used to transport the label paper 14 to the first opening 111. The clamping assembly 13 is rotatably arranged at the first opening 111.

[0035] The first clamping mechanism 3 is arranged corresponding to the first opening 111 , and the first clamping mechanism 3 can approach the clamping assembly 13 to clamp the test tube T, and drive the test tube T to rotate so that the label paper 14 is attached to the test tube T, or the first clamping mechanism 3 is away from the clamping assembly 13 to release the test tube T.

[0036] The test tube T can be a round test tube or a test tube of other shapes, and can be made of glass or other non-metallic materials. The operator can manually place the test tube T near the first opening 111, and clamp the test tube T together with the first clamping mechanism 3 and the pressing assembly 13, and drive the test tube T to rotate so that the label paper 14 is attached to the test tube T. When the label paper 14 is attached to the test tube T, the first clamping mechanism 3 can be moved away from the pressing assembly 13 to release the test tube T.

[0037] The printing device 2 includes a printing chamber 21 and a printing head 22 . The printing chamber 21 is used to receive the test tube T with the label paper 14 attached thereto, and the printing head 22 extends into the printing chamber 21 .

[0038] The second clamping mechanism 4 is arranged opposite to the print head 22. The second clamping mechanism 4 can be close to the print head 22 to clamp the test tube T and drive the test tube T to rotate so that the print head 22 prints a label on the label paper 14, or the second clamping mechanism 4 can be away from the print head 22 to release the test tube T.

[0039] Optionally, the print head 22 is a thermal print head, and the label paper 14 is thermal paper. The thermal print head is provided with a plurality of semiconductor heating elements arranged in a dot matrix or a stripe matrix. Optionally, 320 square dots are provided on the print head 22, and the size of each square dot is 0.25 mm×0.25 mm. With this square dot matrix, after the print head 22 heats and contacts the thermal paper, the print dot can be printed at any position of the thermal paper, and the required pattern can be printed.

[0040] The working principle of the thermal print head 22 is: a transparent film is pasted on a light-colored material (usually paper) to form thermal paper. The semiconductor heating element on the print head 22 heats the transparent film for a period of time and turns it into a dark color (usually black, but also blue). The pattern is generated by a chemical reaction in the film caused by heating. This chemical reaction takes place at a certain temperature, and high temperature will accelerate this chemical reaction. When the temperature is lower than 60°C, it takes a long time, even several years, for the paper to turn dark; when the temperature is 200°C, this reaction will be completed within a few microseconds. The thermal printer selectively heats a certain position on the thermal paper, thereby generating a corresponding pattern.

[0041] The present application provides a label printing device, including a paper supply device 1, a first clamping mechanism 3, a printing device 2, and a second clamping mechanism 4. The paper supply device 1 includes a paper supply bin 11 and a paper supply mechanism 12, a pressing assembly 13, and a label paper 14 arranged in the paper supply bin 11. The paper supply bin 11 has a first opening 111. The paper supply mechanism 12 is used to transport the label paper 14 to the first opening 111. The pressing assembly 13 is rotatably arranged at the first opening 111. The first clamping mechanism 3 is arranged corresponding to the first opening 111. The first clamping mechanism 3 can approach the pressing assembly 13 to clamp the test tube T, and drive the test tube T to rotate so that the label paper 14 is attached to the test tube T, or the first clamping mechanism 3 is away from the pressing assembly 13 to release the test tube T. The printing device 2 includes a printing bin 21 and a printing head 22. The printing bin 21 is used to receive the test tube T with the label paper 14 attached, and the printing head 22 extends into the printing bin 21. The second clamping mechanism 4 is arranged opposite to the print head 22, and the second clamping mechanism 4 can be close to the print head 22 to clamp the test tube T, and drive the test tube T to rotate so that the print head 22 prints a label on the label paper 14, or the second clamping mechanism 4 can be away from the print head 22 to release the test tube T. The labeling and printing device can automatically attach the label paper 14 to the test tube T and automatically print the label on the label paper 14, which is convenient and fast to use, and improves the accuracy of printing the label on the test tube.

[0042] The specific structure of the labeling and printing device for test tubes provided in the embodiment of the present application is further described in detail below in conjunction with the accompanying drawings.

[0043] See again Figure 1 The paper feeding mechanism 12 includes a driving wheel 121, a guide wheel assembly 122 and a paper feeding wheel 123. One end of the label paper 14 is wound around the paper feeding wheel 123, and the other end is wound around the driving wheel 121 via the guide wheel assembly 122. The guide wheel assembly 122 includes at least a first guide wheel 1221 arranged between the clamping assemblies 13. The driving wheel 121 rotates to transport the label paper 14 to the first opening 111.

[0044] Optionally, the clamping assembly 13 includes a first clamping wheel 131 and a second clamping wheel 132, the first guide wheel 1221 is disposed between the first clamping wheel 131 and the second clamping wheel 132, and the label paper 14 is wound from the paper supply wheel 123 to the first guide wheel 1221, and then to the driving wheel 121. When the test tube T is located at the first opening 111, the first clamping mechanism 3 and the clamping assembly 13 clamp the test tube T together, so that the label paper 14 that has bypassed the first guide wheel 1221 is attached to the test tube T.

[0045] In some embodiments, the guide wheel assembly 122 also includes a plurality of second guide wheels 1222, and the plurality of second guide wheels 1222 are respectively arranged between the driving wheel 121 and the first guide wheel 1221 and between the paper supply wheel 123 and the first guide wheel 1221 to form two sections of label paper around the first guide wheel 1221, and the two sections of label paper are arranged at an acute angle θ.

[0046] Optionally, the label paper 14 includes a conveying paper and a plurality of sub-label papers pasted on the conveying paper, and the pressing component 13 is used to peel the sub-label paper from the conveying paper and paste the sub-label paper to the test tube T when the test tube T is close to the pressing component 13. The sub-label paper includes a relative pasting surface and a printing surface, the pasting surface is sticky and can be pasted on the conveying paper or the test tube T, and the printing surface is used to print information such as labels.

[0047] like Figure 1 As shown, a second guide wheel 1222 is provided between the driving wheel 121 and the first guide wheel 1221, and one end of the label paper 14 away from the paper supply wheel 123 is fixed on the driving wheel 121 to generate a preload force to drive the label paper 14 to move. Three second guide wheels 1222 are also provided between the paper supply wheel 123 and the first guide wheel 1221, wherein two second guide wheels 1222 are located on the side of the label paper 14 away from the paper supply wheel 123, and another second guide wheel 1222 is located between the aforementioned two second guide wheels 1222 and on the side of the label paper 14 close to the paper supply wheel 123, so that the tension of the label paper 14 between the driving wheel 121 and the paper supply wheel 123 can be increased by the guide wheel assembly 122.

[0048] In addition, the arrangement of the multiple second guide wheels 1222 of the guide wheel assembly 122 is such that the two sections of label paper that bypass the first guide wheel 1221 are set at an acute angle θ. Optionally, 30°≤θ≤60°, so that a section of sub-label paper of the label paper that moves to the first opening 111 can be peeled off from the conveying paper when it is about to bypass the first guide wheel 1221 and change direction, and pasted on the test tube T, and the conveying paper is wound on the driving wheel 121. As the first clamping mechanism 3 drives the test tube T to rotate, the first clamping wheel 131 can press one end of the sub-label paper to the test tube T, and the second clamping wheel 132 can press the other end of the sub-label paper to the test tube T to prevent the corners of the sub-label paper from curling up. Optionally, the length of the sub-label paper is less than or equal to the circumference of the test tube T, so that the sub-label paper can be completely pasted on the test tube T.

[0049] In some embodiments, the paper feeding mechanism 12 further includes a storage device 124, which is disposed downstream of the driving wheel 121. A second guide wheel 1222 is further disposed between the driving wheel 121 and the storage device 124, and is used to guide the conveyed paper from the driving wheel 121 to the storage device 124.

[0050] Optionally, the storage device 124 is a rotatable shaft, and one end of the label paper 14 away from the paper supply wheel 123 is fixed on the storage device 124 to generate a pre-tightening force to drive the label paper 14 to move. As the storage device 124 rotates, the conveying paper of the label paper 14 can be wound around the storage device 124.

[0051] like Figure 1 As shown, the two second guide wheels 1222 are arranged between the driving wheel 121 and the storage device 124, and the two second guide wheels 1222 are respectively located on the side of the conveying paper close to the driving wheel 121 and the side away from the driving wheel 121, thereby increasing the tensioning force of the conveying paper between the driving wheel 121 and the storage device 124, and preventing the sub-label paper of the label paper 14 from being unable to be peeled off from the conveying paper due to insufficient tensioning force.

[0052] In some embodiments, the printing chamber 21 includes a first portion 211 , a second portion 212 , and a third portion 213 which are sequentially distributed.

[0053] A second opening 2111 is provided at one end of the first portion 211 away from the second portion 212, and the second opening 2111 is used to receive a plurality of test tubes T released from the first clamping mechanism 3. Optionally, a buffer 2112 is further provided at the second opening 2111 of the first portion 211, and the longitudinal cross-section of the buffer 2112 is an arc-shaped structure bent toward the second portion 212, and is used to buffer the impact force of the plurality of test tubes T released from the first clamping mechanism 3, so as to prevent the test tubes T from being damaged by a large collision with the inner wall of the printing chamber 21.

[0054] A rotatable first stirring wheel 2121 is disposed in the second part 212. The first stirring wheel 2121 is provided with a plurality of first grooves 2122 along its circumference, and each first groove 2122 is used to accommodate a test tube T placed along its axial direction. The first stirring wheel 2121 can be driven to rotate by a driving motor, or can be manually rotated by an operator. The first stirring wheel 2121 can stir a plurality of randomly placed test tubes T, so that each test tube T can be placed in the first groove 2122 along its axial direction, thereby orderly adjusting the plurality of test tubes T and transporting them to the third part 213.

[0055] The third portion 213 is used to accommodate a plurality of test tubes T that fall off from the first stirring wheel 2121 , and the plurality of test tubes T are placed side by side along their own axis. The print head 22 and the second clamping mechanism 4 are disposed relatively to the third portion 213 .

[0056] Optionally, the first part 211, the second part 212 and the third part 213 of the printing chamber 21 are distributed in sequence in the vertical direction, so that after being stirred by the first stirring wheel 2121, the multiple test tubes T automatically fall off from the first groove 2122 of the first stirring wheel 2121 to the third part 213 under the action of their own gravity.

[0057] In some embodiments, the third portion 213 includes a straight segment 213a and an inclined segment 213b inclined relative to the straight segment 213a, the straight segment 213a is provided with a third opening 2131 running through it, the print head 22 and the second clamping mechanism 4 are arranged relative to the third opening 2131, and the inclined segment 213b is further provided with a fourth opening 2132 at one end away from the straight segment 213a for releasing the test tube T.

[0058] The print head 22 and the second clamping mechanism 4 are arranged relative to the third opening 2131 of the straight section 213a, so that the second clamping mechanism 4 can clamp the test tube T placed along its own axis and falling off from the first groove 2122 of the first stirring wheel 2121, and print a label on the test tube T through the print head 22. The test tube T with the label printed automatically slides into the inclined section 213b under the action of its own gravity, and is released through the fourth opening 2132.

[0059] In some embodiments, the printing device 2 further includes a sensor 5, which is disposed at the inclined section 213b and is used to count the number of test tubes T. Optionally, the sensor 5 is an infrared sensor. When the number of test tubes T counted by the sensor 5 is less than the number of test tubes T that can be stored in the inclined section 213b, the first stirring wheel 2121 can be continuously controlled to rotate to release more test tubes T, or the print head 22 can be continuously controlled to print labels on the test tubes T until the number of test tubes T counted by the sensor 5 is equal to the number of test tubes T that can be stored in the inclined section 213b. This arrangement can prevent the test tubes T from being blocked in the inclined section 213b.

[0060] Figure 2 Show Figure 1 The enlarged structural diagram of area A of the label printing device shown in FIG. Figure 3 Show Figure 2 A schematic cross-sectional structure diagram of the first clamping mechanism is shown.

[0061] like Figure 2 and Figure 3 As shown, the first clamping mechanism 3 includes a movable first support plate 30, a first driving device 33, a first roller 31 and a second roller 32, the first driving device 33 is fixedly connected to the first support plate 30, the first roller 31 is pivotally connected to the first support plate 30, and the second roller 32 is connected to the output shaft of the first driving device 33;

[0062] The first clamping mechanism 3 drives the first roller 31 and the second roller 32 to approach or move away from the pressing assembly 13 through the first supporting plate 30 , and drives the test tube T to rotate through the second roller 32 .

[0063] In some embodiments, the first clamping mechanism 3 further includes a fourth driving device, and an output shaft of the fourth driving device is connected to the first support plate 30 to drive the first support plate 30 to reciprocate or rotate relative to the clamping assembly 13 .

[0064] Optionally, the fourth driving device is a linear motion mechanism, for example, the fourth driving device includes a linear motor or a cylinder, a hydraulic cylinder, etc., which can drive the first support plate 30 to reciprocate relative to the clamping assembly 13. When the first clamping mechanism 3 needs to clamp the test tube T, the fourth driving device drives the first support plate 30 to drive the first roller 31 and the second roller 32 to move linearly toward the clamping assembly 13, and drives the second roller 32 to rotate the test tube T through the first driving device 33. When the first clamping mechanism 3 needs to release the test tube T, the fourth driving device drives the first support plate 30 to drive the first roller 31 and the second roller 32 to move linearly in a direction away from the clamping assembly 13.

[0065] Further optionally, the fourth drive device also includes a guide assembly, such as a guide rail and a slider slidably connected to the guide rail, wherein the slider is connected to the first support plate 30, thereby preventing the first support plate 30 from deflecting during the reciprocating movement relative to the clamping assembly 13.

[0066] Alternatively, if Figure 3 As shown, the fourth driving device is a rotary motion mechanism, such as a rotary motor, which can drive the first support plate 30 to reciprocate relative to the clamping assembly 13. When the fourth driving device drives the first support plate 30 to drive the first roller 31 and the second roller 32 to rotate toward the clamping assembly 13, for example, the first support plate 30 rotates in the counterclockwise direction, the first clamping mechanism 3 and the clamping assembly 13 can clamp the test tube T together, and at the same time, the first driving device 33 drives the second roller 32 to drive the test tube T to rotate, so as to paste the sub-label paper on the test tube T. When the sub-label paper is pasted, the fourth driving device drives the first support plate 30 to drive the first roller 31 and the second roller 32 to rotate in a direction away from the clamping assembly 13, for example, the first support plate 30 rotates in the clockwise direction, and the first clamping mechanism 3 and the clamping assembly 13 can release the test tube T together.

[0067] Further optionally, the fourth drive device also includes a reduction device, such as a reduction gear set according to a certain transmission ratio, and the output shaft of the reduction gear is connected to the first support plate 30, so as to increase the rotational torque of the first support plate 30, reduce the rotation speed of the first support plate 30, and prevent the first support plate 30 from rotating too fast and damaging the test tube T or the clamping assembly 13.

[0069] In some embodiments, Figure 4 As shown, the second clamping mechanism 4 includes a movable second support plate 40, a third driving device 43, a third roller 41 and a fourth roller 42. The third driving device 43 is fixedly connected to the second support plate 40, the third roller 41 is pivotally connected to the second support plate 40, and the fourth roller 42 is connected to the output shaft of the third driving device 43.

[0070] The second clamping mechanism 4 drives the third roller 41 and the fourth roller 42 to approach or move away from the print head 22 through the second supporting plate 40 , and drives the test tube T to rotate through the fourth roller 42 .

[0071] In some embodiments, the second clamping mechanism 4 further includes a fourth driving device (not shown in the figure), the output shaft of which is connected to the second support plate 40 to drive the second support plate 40 to reciprocate or rotate relative to the print head 22 .

When the second clamping mechanism 4 needs to clamp the test tube T, the fourth driving device drives the second support plate 40 to drive the third roller 41 and the fourth roller 42 to move linearly toward the print head 22, and drives the fourth roller 42 to rotate the test tube T through the first driving device 33. When the second clamping mechanism 4 needs to release the test tube T, the fourth driving device drives the second support plate 40 to drive the third roller 41 and the fourth roller 42 to move linearly in a direction away from the print head 22.

[0073] Further optionally, the fourth driving device also includes a guiding assembly, such as a guide rail and a slider slidably connected to the guide rail, wherein the slider is connected to the second support plate 40, thereby preventing the second support plate 40 from deflecting during the reciprocating movement relative to the print head 22.

[0074] Alternatively, if Figure 3As shown, the fourth driving device is a rotary motion mechanism, such as a rotary motor, which can drive the second support plate 40 to reciprocate relative to the print head 22. When the fourth driving device drives the second support plate 40 to drive the third roller 41 and the fourth roller 42 to rotate toward the print head 22, for example, the second support plate 40 rotates in the counterclockwise direction, the second clamping mechanism 4 and the print head 22 can clamp the test tube T together, and at the same time, the first driving device 33 drives the fourth roller 42 to drive the test tube T to rotate, so as to paste the sub-label paper on the test tube T. When the sub-label paper is pasted, the fourth driving device drives the second support plate 40 to drive the third roller 41 and the fourth roller 42 to rotate in a direction away from the print head 22, for example, the second support plate 40 rotates in the clockwise direction, and the second clamping mechanism 4 and the print head 22 can release the test tube T together.

[0075] Further optionally, the fourth drive device also includes a deceleration device, such as a reduction gear set according to a certain transmission ratio, and the output shaft of the reduction gear is connected to the second support plate 40, so as to increase the rotational torque of the second support plate 40, reduce the rotation speed of the second support plate 40, and prevent the second support plate 40 from rotating at too high a speed and damaging the test tube T or the print head 22.

The second stirring wheel 621 is provided with a plurality of second grooves 622 along its circumference, and each second groove 622 is used to accommodate a test tube T placed along its axial direction. The second stirring wheel 621 can be driven to rotate by a driving motor, or can be manually rotated by an operator. The second stirring wheel 621 can stir the multiple randomly placed test tubes T, so that each test tube T can be placed in the second groove 622 along its axial direction, thereby orderly adjusting the multiple randomly placed test tubes T and transporting them to the sixth part 63.

[0082] The sixth portion 63 is used to accommodate multiple test tubes T that fall off the second stirring wheel 621 , and the multiple test tubes T are placed side by side along their own axis. The sixth opening 631 is set at one end of the third portion 213 away from the second portion 212 to release the test tubes T.

[0083] Optionally, the fourth part 61, the fifth part 62 and the sixth part 63 of the storage bin 6 are distributed in sequence in the vertical direction, so that after being stirred by the second stirring wheel 621, the multiple test tubes T automatically fall off from the second groove 622 of the second stirring wheel 621 to the sixth part 63 under the action of their own gravity.

[0084] In some embodiments, Figure 5 As shown, the labeling and printing device also includes a shell 10, the shell 10 has a accommodating cavity and an outlet connected to the accommodating cavity, the accommodating cavity is used to accommodate the paper supply device 1, the printing device 2, the first clamping mechanism 3 and the storage bin 6, and the outlet corresponds to the sixth opening 631 of the storage bin 6, so that the test tube T with the printed label information can be taken out from the outlet, or a storage box 7 can be set at the outlet for storing the test tube T with the printed label information.

[0085] Optionally, the paper supply bin 11 and the storage bin 6 are arranged side by side above the printing device 2, and the first opening 111 of the paper supply bin 11 and the sixth opening 631 of the storage bin 6 are respectively arranged corresponding to the first clamping mechanism 3. A partition is arranged between the paper supply bin 11 and the storage bin 6 and the printing device 2, and a through hole is opened on the partition. Below the first clamping mechanism 3 is the printing bin 21, which is used to accommodate the test tube T with the label paper 14 attached thereto released from the first clamping mechanism 3.

[0086] The outer shell 10 accommodates the paper supply device 1, the printing device 2, the first clamping mechanism 3 and the storage bin 6 in the accommodating cavity. On the one hand, it can prevent dust and other impurities from falling into the first clamping mechanism 3 or the storage bin 6 and affecting the normal operation of the labeling and printing equipment. On the other hand, it improves the aesthetics of the labeling and printing equipment.
