Description

Technical Field

[0001] This utility model relates to the field of test tube labeling technology, specifically to a floor-standing test tube labeling machine. Background Technology

[0002] A test tube labeling machine is a machine that affixes labels to the surface of test tubes. The general workflow of existing test tube labeling machines is as follows: a batch of test tubes to be labeled are loaded into the test tube labeling machine, the machine identifies the position of the test tubes, then prepares an adhesive label, and then affixes the adhesive label to the body of each test tube in turn.

[0003] Existing test tube labeling machines generally have the following problems: (1) The requirements for the placement of test tubes are quite strict. Users need to neatly stack each test tube to be labeled in the labeling machine, which is extremely labor-intensive and inefficient; (2) Due to the strict requirements for the placement of test tubes, the test tubes to be labeled will not be moved during the labeling process. Instead, the labeling mechanism is used to apply the label to each test tube in turn. Since the labeling mechanism itself has a certain volume, the spacing between the test tubes to be labeled is also required to avoid the adjacent test tubes from hindering the movement of the labeling mechanism, which results in a significant reduction in the number of test tubes to be labeled per unit volume; (3) The labeled test tubes cannot be discharged by themselves after labeling and still need to be manually removed, which is labor-intensive and inefficient.

[0016] Compared with the prior art, this utility model has the following advantages and beneficial effects:

[0017] This utility model provides a floor-standing test tube labeling machine. By setting a loading frame with multiple loading tracks at its top and limiting the width of the tracks, test tubes to be labeled can be vertically inserted into the tracks while the bottom of the tube cap rests on the top surface of the tracks. This allows the test tubes to slide sequentially from the high end to the low end of the tracks, gradually and neatly stacking them within each track, thus achieving efficient and orderly stacking of the test tubes. Furthermore, by setting a pair of elastic clamps at the low end of the loading tracks and limiting the distance between them, the test tubes at the lowest point are clamped between the corresponding pair of elastic clamps.

The translation joint moves the tube-retrieving lever to directly above the test tube to be labeled, and the lifting joint moves the tube-retrieving lever downwards, pressing down on the corresponding test tube, causing it to move downwards and be squeezed outwards by the tube cap. The elastic clamps are extended until the test tube to be labeled falls into the receiving mechanism, allowing one of the neatly stacked test tubes on the loading rack to be accurately removed. After removal, the next test tube to be labeled is clamped between the corresponding elastic clamps under the gravity and pressure of the other test tubes. Repeating the above operation, all the test tubes to be labeled on the loading rack can be removed sequentially. By setting the labeling mechanism with its inlet connected to the receiving mechanism, the test tubes on the loading rack can be moved to the labeling mechanism for labeling without moving the labeling mechanism itself. This eliminates the need to deliberately increase the spacing between the test tubes and effectively increases the unit number of test tubes to be labeled in the labeling machine. Furthermore, by setting the tube transfer mechanism and tube discharge mechanism, the labeled test tubes are discharged from the labeling machine. Through the cooperation of the above features, this floor-standing test tube labeling machine can effectively solve the problems of existing test tube labeling machines, which have strict requirements on the placement of test tubes, require a large amount of neat stacking work, and have extremely low efficiency.

[0034] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the embodiments and accompanying drawings. The illustrative embodiments and descriptions of this utility model are only used to explain this utility model and are not intended to limit this utility model.

[0035] Please refer to Figures 1 to 9 This utility model provides a floor-standing test tube labeling machine, comprising: a loading frame 10, the top of which has multiple loading slides 12, the lower ends of which are located on the same horizontal line; the width of each loading slide 12 is slightly larger than the outer diameter of the test tube body to be labeled, but smaller than the outer diameter of the cap of the test tube to be labeled; a pair of elastic clips 15 are vertically provided at the lower end of each loading slide 12, the spacing of which is smaller than the outer diameter of the cap of the test tube to be labeled when the elastic clips 15 are in their natural state; and a tube-retrieving mechanism, which includes a translation pair, a lifting pair, a tube-retrieving lever 21, and a tube-retrieving mechanism; the translation pair extends along all the loading slides 12. The lower end of the 2nd section is moved horizontally, the lifting joint is located on the horizontal joint, the tube-retrieving lever 21 is located on the lifting joint and is directly above the line connecting the lower ends of all the loading slides 12, the connecting mechanism is located directly below the tube-retrieving lever 21, the tube-retrieving lever 21 is used to press down the test tube to be labeled between any pair of elastic clips 15 so that the test tube to be labeled falls into the connecting mechanism; the third section includes multiple labeling mechanisms, the inlets of all the labeling mechanisms are respectively connected to the connecting mechanism, the labeling mechanism is used to label the test tube to be labeled; the fourth section includes a tube-transfer mechanism and a tube-discharge mechanism, the tube-transfer mechanism and the tube-discharge mechanism are used to discharge the labeled test tube.

[0036] The floor-standing test tube labeling machine provided in this embodiment, by setting a loading rack 10 with multiple loading slides 12 on its top and limiting the width of the loading slides 12, allows the test tubes to be labeled to be vertically inserted into the loading slides 12 while the bottom surface of the tube cap rests on the top surface of the loading slides 12. This allows the test tubes to be labeled to slide sequentially along the loading slides 12 from the high end to the low end, and gradually and neatly stacked within each loading slide 12, thus achieving efficient and orderly stacking of the test tubes to be labeled. Based on this, by... A pair of elastic clamps 15 are provided at the lower end of the loading slide 12, and the distance between the pair of elastic clamps 15 is limited so that the test tube to be labeled at the lowest point is clamped between the corresponding pair of elastic clamps 15. A tube-retrieving mechanism is provided, which includes a translation pair, a lifting pair, a tube-retrieving lever 21, and a tube-connecting mechanism. The translation pair moves the tube-retrieving lever 21 to move it directly above the test tube to be labeled. The lifting pair moves the tube-retrieving lever 21 down to press down the corresponding test tube to be labeled, so that the test tube to be labeled moves down and passes through. By squeezing the cap outwards and opening the elastic clamp 15 until the test tube to be labeled falls into the connecting mechanism, one of the neatly stacked test tubes to be labeled on the loading rack 10 can be accurately removed. After removal, the next test tube to be labeled will be clamped between the corresponding elastic clamps 15 under the gravity and pressure of the other test tubes to be labeled. By repeating the above operation, all the test tubes to be labeled on the loading rack 10 can be removed in sequence. By setting the labeling mechanism so that its inlet is connected to the connecting mechanism, the connecting mechanism can be used to remove the test tubes on the loading rack 10. The test tubes are moved to the labeling mechanism for labeling without moving the labeling mechanism itself, thus eliminating the need to deliberately increase the spacing between the test tubes and effectively increasing the number of test tubes that can be labeled within the labeling machine. Furthermore, by setting up a tube transfer mechanism and a tube discharge mechanism, the labeled test tubes are discharged from the labeling machine. Through the cooperation of the above features, this floor-standing test tube labeling machine can effectively solve the problems of existing test tube labeling machines, which have strict requirements on the placement of test tubes, require a large amount of work for neat stacking, and have extremely low efficiency.

[0037] To further explain the specific structure of the loading rack 10 and the loading slide 12, the top of the loading rack 10 is provided with a loading surface 11, which is an inclined plane, so that the highest side of the loading surface 11 forms a loading side and the lowest side of the loading surface 11 forms a loading side; all the loading slides 12 are opened on the loading surface 11, and the two ends of the loading slide 12 are located on the loading side and the loading side, respectively.

[0038] To further explain the specific structure of the loading rack 10, the loading rack 10 includes a loading plate 101, a low-position support plate 102, and a high-position support plate 103; the loading plate 101 is inclined, the upper surface of the loading plate 101 is the loading surface, the loading slide 12 is formed on the loading plate 101, and the loading slide 12 passes through the loading plate 101 along the thickness direction of the loading plate 101; one side of the low-position support plate 102 is connected to the lowest side of the loading plate 101, and the opposite side is used to contact the ground; one side of the high-position support plate 103 is connected to the highest side of the loading plate 101, and the opposite side is used to contact the ground.

[0039] With the above settings, the loading rack 10 is made as lightweight as possible while ensuring structural and support performance, and does not obstruct the tube body of the test tube to be labeled, allowing the status of each test tube to be labeled to be clearly observed from the side.

[0040] Preferably, the loading plate 101, the low-position support plate 102, and the high-position support plate 103 are integrally formed.

[0041] To further enhance structural stability, the high-position support plate 103 is vertically arranged; the low-position support plate 102 is inclined toward the high-position support plate 103 and forms an acute angle with the loading plate 101; the middle parts of both the low-position support plate 102 and the high-position support plate 103 are hollowed out.

[0042] To accommodate test tubes of different diameters to be labeled, all the loading slides 12 have different widths; the loading slides 12 are straight slides, and all the loading slides 12 are arranged in parallel and at equal intervals.

[0043] To prevent unnecessary swaying when the test tubes to be labeled slide down, the loading slide 12 extends in a vertical plane; a guide sliding plate 14 is provided on each side of the loading plate 101 in the width direction, and the guide sliding plate 14 is arranged parallel to the loading slide 12; a gap is reserved between the guide sliding plate 14 and the loading plate 101, and the width of the gap is less than the length of the test tube to be labeled.

[0044] To further explain the specific mechanism of the lower end of the loading slide 12, the lower end of the loading slide 12 is configured to form a tube-retrieving port. The width of the tube-retrieving port is greater than the diameter of the cap of the test tube to be labeled. The elastic clamp 15 is located inside the tube-retrieving port. The top side of the elastic clamp 15 is inclined. When the test tube to be labeled is pressed down, the cap of the test tube to be labeled can be pressed in and open the elastic clamp 15. The loading side of the loading frame 10 is provided with a baffle 13. When the test tube to be labeled is located inside the tube-retrieving port, the test tube to be labeled contacts and is squeezed by the baffle 13.

[0045] It should be noted that during the free fall process when the test tube is pressed down by the tube removal lever 21, the baffle 13 can ensure that the tilt angle of the test tube is as small as possible when it falls, so that it can successfully fall into the tube receiving mechanism.

[0046] To further explain the specific structure of the baffle 13, the baffle 13 includes a front baffle 131 and a pair of side baffles 132; the front baffle 131 is located on the lowest side of the loading plate 101, the front baffle 131 is vertically arranged, and the top side of the front baffle 131 is higher than the lowest side of the loading plate 101; the two side baffles 132 are respectively located at both ends of the front baffle 131 in the length direction, and are vertically arranged, and are parallel to the loading slide 12.

[0047] In order to further improve the shielding area and overall structural performance of the side baffle 132, the side baffle 132 is wedge-shaped and matches the angle of the low support plate 102. The side of the side baffle 132 near the low support plate 102 is perpendicularly arranged and connected to the low support plate 102.

[0048] It should be noted that the tube-taking mechanism includes a base frame 20, and the translation pair is disposed on the base frame 20.

[0049] It should be noted that the above-mentioned lifting and translation joints can adopt any of the relevant mechanisms in the existing technology. For example, a slide rail and slider structure can be used in conjunction with a motor and track for driving, or a motor and gear set can be used for driving. Alternatively, a cylinder or hydraulic cylinder can be used for pushing and pulling, as long as it can achieve lifting or translation.

[0050] In order to make the tube picking lever 21 have a certain degree of elasticity, a large contact area, and be lightweight enough, the tube picking lever 21 includes a vertical plate 211 and a horizontal plate 212. The top of the vertical plate 211 is connected to the lifting pair, and the bottom is connected to the horizontal plate 212, so that the tube picking lever 21 is L-shaped. The bottom surface of the horizontal plate 212 is used to contact and press down the test tube to be labeled.

[0051] With the above settings, even if the test tube to be labeled is tilted to a certain extent, it can be effectively pressed down and corrected by the tube removal lever.

[0052] To further optimize the structure of the tube-retrieving lever 21 and improve its stress distribution, the longitudinal lever 211 includes a vertical portion 2111 and an inclined portion 2112. The top of the vertical portion 2111 is connected to the lifting joint. The top of the inclined portion 2112 is connected to the bottom of the vertical portion 2111, and the bottom is connected to the horizontal lever 212. The inclined portion 2112 is set at an obtuse angle to the vertical portion 2111, so that the middle part of the horizontal lever 212 is located directly below the vertical portion 2111.

[0053] To improve the overall structural performance of the tube-retrieving lever 21, the vertical part 2111, the inclined part 2112, and the horizontal piece 212 are integrally formed.

[0054] In order to indicate and calibrate the displacement distance of the translation pair, the frame 20 is provided with a channel code plate 22. The channel code plate 22 extends along the moving direction of the translation pair, and the channel code plate 22 is provided with a plurality of code teeth evenly spaced along the length direction. The code teeth are used to indicate and calibrate the displacement distance of the translation pair.

[0055] To further explain the specific structure of the take-up mechanism, the take-up mechanism includes a tube transfer hopper 23 and a positioning horizontal plate 30; the tube transfer hopper 23 is vertically arranged on the translation joint, with the opening of the tube transfer hopper 23 facing upwards, and the lowest point of the tube take-up lever 21 located above the opening of the tube transfer hopper 23 and close to the loading frame 10; the outlet diameter of the tube transfer hopper 23 is slightly larger than the diameter of the test tube to be labeled; the positioning horizontal plate 30 is horizontally arranged below the tube transfer hopper 23 and extends along the moving direction of the translation joint. The plate 30 has a plurality of positioning holes 31 spaced apart. The positioning holes 31 vertically penetrate the positioning plate 30. The diameter of the positioning holes 31 is slightly larger than the diameter of the pre-labeled test tubes. Any one of the positioning holes 31 can be aligned with the outlet of the tube transfer hopper 23. The labeling mechanism corresponds one-to-one with the positioning holes 31. The labeling mechanism is provided with a test tube groove 32. The test tube groove 32 is located directly below the corresponding positioning hole 31 and aligned with the corresponding positioning hole 31. The labeling mechanism is used to label the test tubes to be labeled that fall into the test tube groove 32.

[0056] With the above setup, the shape of the tube transfer bucket 23 is used to effectively collect and catch the falling test tubes to be labeled. Then, the tubes are lifted by the positioning plate 30 and move together with the tube transfer bucket 23. When the tube transfer bucket 23 moves to be aligned with any of the positioning holes 31, the test tubes to be labeled will fall into the positioning holes 31 and into the test tube slots 32 of the corresponding labeling mechanism.

[0057] In order to keep the test tubes to be labeled in the tube transfer container 23 in a vertical position so as to facilitate sliding out during subsequent tube removal, the tube transfer container 23 includes a conical part 231 and a vertical cylindrical part 232. The conical part 231 and the vertical cylindrical part 232 are coaxially connected and communicate with each other. The inner diameter of the vertical cylindrical part 232 is slightly larger than the diameter of the test tubes to be labeled.

[0058] To further prevent the test tubes to be labeled from falling out of the opening of the tube transfer hopper 23, an arc-shaped baffle 233 is provided at the opening of the conical part 231, and the slope of the baffle 233 matches the slope of the conical part 231.

[0059] Preferably, the translation pair is provided with a monitoring optocoupler 24, which is used to monitor the amount of test tubes to be labeled loaded on the loading rack.

[0060] To further explain the specific shape of the positioning plate 30, the positioning plate 30 is strip-shaped, and all the positioning holes 31 are evenly spaced along the length of the positioning plate 30; the labeling mechanism is provided with a base plate 33, which is arranged parallel to the bottom of the positioning plate 30 and connected to the positioning plate 30 through a support plate 34. The support plate 34 is provided on the opposite two sides of the base plate 33 and is arranged perpendicular to the positioning plate 30.

[0061] The above settings create a certain height difference between the positioning plate 30 and the base plate 33, which allows for radial positioning of the test tubes to be labeled at two different heights, thereby effectively ensuring their vertical setting.

[0062] In order to effectively support the entire device, all the substrates 33 are located on the same plane; multiple support legs 35 are vertically provided at the bottom of the substrates 33, and all the support legs 35 are of the same length.

[0063] To further explain the specific structure of the labeling mechanism, the labeling mechanism includes a printer 36 and a labeling machine 37, which are respectively disposed on the top surface of the substrate 33; the printer 36 is used to print labels; the labeling machine 37 is used to affix the labels to the tube wall of the test tube to be labeled.

[0064] It should be noted that the printer 36 and labeling machine 37 mentioned above can be any of the relevant devices in the prior art, as long as they can print the label and send it to the side wall of the test tube to be labeled.

[0065] Preferably, the test tube trough 32 is located in the labeling machine 37.

[0066] To further ensure the verticality of the test tubes to be labeled, a clamping mechanism is provided on the side wall of the test tube groove 32. The clamping mechanism is used to clamp the test tubes to be labeled in the test tube groove 32.

[0067] To further explain the specific structure of the clamping mechanism, the clamping mechanism includes a pair of jaws and an opening and closing mechanism. The jaws are slidably arranged along the radial direction of the test tube groove 32, and the opening and closing mechanism is used to control the two jaws to move closer or further apart from each other.

[0068] Optionally, the opening and closing mechanism is a pneumatic cylinder or a hydraulic cylinder. Two pneumatic or hydraulic cylinders push the two grippers closer together or further apart via push rods to achieve clamping.

[0069] Optionally, the opening and closing mechanism includes a motor and a double-ended screw. The motor is driven by the double-ended screw, and the threads at both ends of the double-ended screw are arranged in opposite directions. The two grippers are screwed onto both ends of the double-ended screw, respectively. The motor drives the double-ended screw to rotate, thereby causing the grippers screwed onto its two ends to move closer or further apart, thus performing clamping.

[0070] To further facilitate labeling, the test tube slot 32 is equipped with a horizontal rotation mechanism. The gripper and the opening and closing mechanism are both located in the rotation mechanism, which can drive the test tube to be labeled to rotate around the axis.

[0071] With the above settings, the rotating mechanism drives the gripper to rotate, thereby causing the test tube to be labeled held by the gripper to rotate synchronously. When the labeling machine 37 presses the label against the wall of the test tube to be labeled, the rotation of the test tube will roll the label from one side to the other.

[0072] To further explain the specific structure of the tube transfer mechanism, the bottom of the test tube trough 32 is provided with an opening and closing stop (not shown in the figure); the tube transfer mechanism includes a tube transfer track 40 and a tube transfer bucket 42; the tube transfer track 40 is slidably provided with a movable seat 41, and the movable seat 41 is connected to the tube transfer track 40 through a driving mechanism; the tube transfer bucket 42 is vertically arranged on the movable seat 41, the opening of the tube transfer bucket 42 is arranged facing upward, the tube transfer bucket 42 is located directly below the test tube trough 32, and slides along the line connecting all the test tube troughs 32, and the tube transfer bucket 42 is used to hold labeled test tubes.

[0073] With the above settings, once the test tubes to be labeled in the test tube trough 32 have been labeled, the opening and closing lever will move aside, and the labeled test tubes will fall from the test tube trough 32 and into the transfer hopper 42 located below.

[0074] It should be noted that in this embodiment, the opening and closing lever is a rod-shaped object with a single-end rotatable connection. It is connected to one side by a motor. When it is rotated to the horizontal, it is horizontal to the bottom of the test tube tank 32 to close it. When it is rotated to the vertical downward, the bottom of the test tube tank 32 is open.

[0075] It should be noted that the bottom of the transfer container 42 is sealed to prevent labeled test tubes from falling out of its bottom.

[0076] To further explain the specific structure of the drive mechanism, the drive mechanism includes a driving roller 43, a driven roller 44, a transmission belt 45, and a tube-moving motor 46; the driving roller 43 and the driven roller 44 are respectively rotatably disposed at both ends of the tube-moving track 40, and the driving roller 43 and the driven roller 44 are arranged in parallel and located in the same plane; the transmission belt 45 is wound around and supported on the driving roller 43 and the driven roller 44, and the moving seat 41 is fixedly connected to the transmission belt 45; the tube-moving motor 46 is disposed on the tube-moving track 40 and is drively connected to the driving roller 43.

[0077] To prevent the drive belt 45 from disengaging from the drive roller 43 and the driven roller 44, the drive roller 43 and the driven roller 44 have grooves 431 cut inward on their wheel surfaces, and the width of the grooves 431 matches the width of the drive belt 45.

[0078] In order to improve the transmission force and avoid unnecessary relative slippage between the transmission belt 45 and the driving roller 43 and the driven roller 44, the groove surface of the belt groove 431 is provided with transmission teeth; the inner surface of the transmission belt 45 is provided with tooth grooves 451 that match the transmission teeth.

[0079] To further explain the specific structure of the transfer track 40, the transfer track 40 includes a longitudinal plate 401 and a transverse plate 402. The longitudinal plate 401 and the transverse plate 402 are strip-shaped plates of the same length extending horizontally. The bottom edge of the longitudinal plate 401 is connected to the side of the transverse plate 402 in the width direction, so that the transfer track 40 is L-shaped. The movable seat 41 is slidably connected to the longitudinal plate 401. The driving roller 43 and the driven roller 44 are respectively located at both ends of the longitudinal plate 401 in the length direction, and are both perpendicular to the longitudinal plate 401.

[0080] In order to monitor the displacement of the movable seat 41, a positioning strip 47 is provided on the top edge of the longitudinal plate 401. The positioning strip 47 extends along the length direction of the longitudinal plate 401, and a plurality of positioning points 471 are provided at intervals along the length direction of the positioning strip 47.

[0081] To further explain the specific structure of the tube transfer bucket 42, the tube transfer bucket 42 includes a conical part 421 and a cylindrical part 422, the conical part 421 and the cylindrical part 422 being coaxially connected; the outer wall of the cylindrical part 422 is detachably inserted into the movable seat 41.

[0082] To further facilitate monitoring of the displacement of the movable seat 41 and to avoid contact and compression between the conical part 421 and the longitudinal plate 401, the cylindrical part 422 is positioned close to the longitudinal plate 401, and the height of the conical part 421 is higher than the height of the top edge of the longitudinal plate 401.

[0083] Preferably, in order to ensure that the test tube to be labeled is properly inserted into the transfer container 42, the inner diameter of the cylindrical part 422 is slightly larger than the outer diameter of the tube body of the test tube to be labeled, and smaller than the outer diameter of the cap of the test tube to be labeled.

[0084] To further explain the specific structure of the tube dispensing mechanism, an axial clearance groove 423 is formed on one side wall of the tube transfer hopper 42, with both ends of the clearance groove 423 penetrating both ends of the tube transfer hopper 42. The tube dispensing mechanism includes a tube dispensing frame 50, a lifting mechanism, a tube dispensing transfer hopper 51, and a tube dispensing slide 52. A tube dispensing lever 424 is slidably mounted on the tube dispensing frame 50 in the vertical direction. The lifting mechanism is located on the tube dispensing frame 50 and causes the tube dispensing lever 424 to rise or fall. The tube dispensing transfer hopper 51 is slightly larger than the outer diameter of the test tube to be dispensed. The tube dispensing transfer hopper 51 is vertically mounted on the tube dispensing frame 50, with the opening of the tube dispensing transfer hopper 51 facing downwards. A tube outlet groove 511 is formed along the axial direction of the wall. The two ends of the tube outlet groove 511 respectively pass through the two ends of the tube outlet transfer bucket 51. The tube outlet groove 511 can be aligned with the clearance groove 423. The tube outlet lever 424 matches the clearance groove 423 and the tube outlet groove 511 and is partially inserted into the clearance groove 423 or the tube outlet groove 511. The tube outlet lever 424 is used to lift the labeled test tube in the tube transfer bucket 42 into the tube outlet transfer bucket 51 and continue to lift it out of the tube outlet transfer bucket 51. The tube outlet slide 52 is provided on the tube outlet rack 50 and is located above the tube outlet transfer bucket 51. It is connected to the top of the tube outlet transfer bucket 51, and the connection point is the highest point of the tube outlet slide 52.

[0085] With the above setup, when discharging the tube, the tube transfer hopper 42 carries the labeled test tube to a position directly below the tube discharging hopper 51. Then, the lifting mechanism drives the tube discharging lever 424 upward until it contacts the bottom of the labeled test tube in the tube transfer hopper 42. The tube discharging lever 424 continues to rise, transferring the labeled test tube from the tube transfer hopper 42 to the tube discharging hopper 51. Continuing to rise, it transfers the tube to the highest point of the tube discharging slide 52, and then slides along the tube discharging slide 52 from the highest point to the lowest point, thus achieving the smooth discharging of the labeled test tube.

[0086] To further explain the specific structure of the tube transfer container 51, the tube transfer container 51 is cylindrical, and the inner diameter of the tube transfer container 51 is slightly larger than the outer diameter of the test tube to be labeled; the length of the tube transfer container 51 is greater than the length of the test tube to be labeled.

[0087] It should be noted that the opening diameter of the funnel is larger than the inner diameter of the funnel body to facilitate the insertion of test tubes to be labeled.

[0088] To further explain the specific structure of the lifting mechanism, the lifting mechanism includes a top roller 53, a bottom roller 54, and a lifting belt 55; the top roller 53 and the bottom roller 54 are respectively located at the top and bottom ends of the tube outlet frame 50, the axes of the top roller 53 and the bottom roller 54 are parallel and located in the same vertical plane, and the top roller 53 or the bottom roller 54 is driven by a lifting motor; the lifting belt 55 is wound around and supported by the top roller 53 and the bottom roller 53; the tube outlet frame 50 is slidably connected to a lifting seat 56 in the vertical direction, the lifting seat 56 is fixedly connected to the lifting belt 55, and the tube outlet lever 424 is located on the lifting seat 56.

[0089] To prevent the labeled test tubes pushed out by the tube ejector 424 from falling back into the tube transfer hopper 51, a pair of elastic limiting plates 512 are provided at the top of the tube transfer hopper 51. The two elastic limiting plates 512 are clamped against the side wall of the tube transfer hopper 51. When the elastic limiting plates 512 are in their natural state, the distance between the two elastic limiting plates 512 is slightly smaller than the outer diameter of the test tube. The elastic limiting plates 512 are vertical strips, and the top of the elastic limiting plates 512 is bent inward at an obtuse angle.

[0090] By setting elastic limiting plates 512, when the labeled test tube rises to the top of the tube transfer hopper 51, the top of the labeled test tube first squeezes the two elastic limiting plates 512 outward, so that the two elastic limiting plates 512 move away from each other until the entire labeled test tube is squeezed out between the two elastic limiting plates 512. Then the two elastic limiting plates 512 are reset, and the distance between them is less than the outer diameter of the tube body of the labeled test tube, so as to prevent the labeled test tube from falling back into the tube transfer hopper 51.

[0091] To prevent the test tubes to be discharged from falling out from both sides of the discharge slide 52 when they are lifted out to the discharge slide 52, the discharge slide 52 is provided with slide walls 521 on both sides, and the height of the slide walls 521 is greater than half the length of the test tubes to be discharged.

[0092] The outlet slide 52 is provided with two branches, which are located on the same vertical plane and extend in opposite directions. A channel divider 522 is hinged at the highest point of the outlet slide 52, and the hinge shaft of the channel divider 522 is located directly above the top of the outlet transfer bucket 51. The hinge shaft of the channel divider 522 is connected to a channel divider motor.

[0093] By setting the channel divider 522, when in use, simply use the channel divider motor to turn the channel divider 522 to a specific angle so that one side completely covers the top of the tube transfer bucket 51, and the lifted test tube to be labeled can be guided to slide to the corresponding branch.

[0094] Preferably, to avoid the test tubes to be labeled accumulating at the highest point of the tube exit slide 52, the slopes of the two branches are different, and the entrance width of the branch with a gentler slope is narrower than the exit width, and the width of the branch transitions smoothly.

[0095] The specific embodiments described above further illustrate the purpose, technical solution, and beneficial effects of this utility model. It should be understood that the above description is only a specific embodiment of this utility model and is not intended to limit the scope of protection of this utility model.
