Detailed Implementation

[0018] The technical solution of this utility model will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0019] In the description of this utility model, it should be understood that the orientation or positional relationship indicated by terms such as "upper", "lower", "left", "right", "inner", "outer", "front", "back", "horizontal", and "vertical" are based on the orientation or positional relationship shown in the accompanying drawings and are only for the convenience of describing this utility model, and are not intended to indicate or imply that the device or component referred to must have a specific orientation, and therefore should not be construed as a limitation of this utility model.

[0020] It should be noted that the terms "horizontal" and "vertical" in this utility model are used to describe approximate positional relationships, and not strictly "horizontal plane" or "vertical plane". Example

[0021] Please refer to Figures 1 to 3 As shown, this embodiment provides a test tube labeling device, including: a fixing mechanism, wherein the fixing mechanism is vertically provided with a fixing groove 30, the fixing groove 30 being used to vertically insert test tubes; a second including a tube-spinning mechanism, the tube-spinning mechanism including a plurality of vertically arranged rotating rollers 31 and a rotating roller motor, the rotating roller motor being drivenly connected to at least one of the rotating rollers 31, all the rotating rollers 31 being arranged in a ring at intervals to form a tube-spinning cavity, the tube-spinning cavity being coaxially arranged with the fixing groove 30, so that the sidewall of the test tube in the fixing groove 30 is in line contact with all the rotating rollers 31; a third including a main printing mechanism, the main printing mechanism being used to print labels, the main printing mechanism being provided with a label outlet, the label outlet being aligned and engaged with the sidewall of the tube-spinning cavity, so that the label at the label outlet is in contact with the sidewall of the test tube in the tube-spinning cavity.

[0022] This utility model discloses a test tube labeling device. A fixing mechanism with a fixing groove 30 is provided within the fixing mechanism for inserting test tubes to be labeled, thus limiting their position and preventing positional and angular deviations during labeling. A rotating tube mechanism is provided, comprising several rotating rollers 31 and a rotating roller 31 motor. All rotating rollers 31 are arranged in a ring at intervals to form a rotating tube cavity, which is coaxial with the fixing groove 30. This ensures that the test tubes located in the fixing groove 30 are also located within the rotating tube cavity, with the sidewalls of the test tubes in line contact with all rotating rollers 31. The rotating roller 31 motor drives at least one rotating roller 31 to rotate, thereby rotating the test tubes through friction. As the tube rotates, the remaining rollers 31 passively rotate with the test tube under the action of friction, thereby stabilizing the position and angle of the test tube during rotation. By setting up a main printing mechanism, labels to be affixed to the test tubes are printed, and the label outlet of the main printing mechanism is aligned with the side wall of the rotating tube cavity, so that the printed labels ejected from the label outlet contact the side wall of the test tube inside the rotating tube cavity. As the test tube rotates, the ejected labels can be attached to the surface of the test tube. Through the cooperation of the above features, this test tube labeling device can effectively solve the problem that when the production or usage of test tubes is large, the manual labeling workload is large and the work efficiency is low, which cannot meet the needs.

[0023] It should be noted that the main printing mechanism mentioned above can be any label printer in the existing technology, as long as it can print labels for affixing.

[0024] To further explain the specific structure of the fixing mechanism, the fixing mechanism includes a fixing frame 32 and a pair of limiting semi-cylinders 33, the two limiting semi-cylinders 33 being able to engage to form the fixing groove 30; at least one of the limiting semi-cylinders 33 is slidably connected to the fixing frame 32 so that the two limiting semi-cylinders 33 can move closer to or further away from each other.

[0025] With the above settings, the width of the fixing groove 30 can be varied to accommodate different types of test tubes. It can effectively fix test tubes with different outer diameters. Specifically, the test tube is fixed by two limiting half-cylinders 33 clamping together.

[0026] To further explain the sliding structure of the limiting half-cylinder 33, one of the limiting half-cylinders 33 is fixedly connected to the fixed frame 32, and the other limiting half-cylinder 33 is slidably connected to the fixed frame 32; the limiting half-cylinder 33 slidably connected to the fixed frame 32 is provided with a rack 331, the rack 331 is arranged parallel to the sliding direction of the corresponding limiting half-cylinder 33, the rack 331 meshes with a fixed gear 332, the fixed gear 332 is driven by a fixed motor, and the fixed motor is fixedly connected to the fixed frame 32.

[0027] With the above settings, one limiting half-cylinder 33 is fixedly connected to the fixed frame 32, so that the two limiting half-cylinders 33 can be moved closer or further apart simply by moving the other limiting half-cylinder 33; by setting a fixed motor, a fixed gear 332 and a rack 331, the fixed motor drives the fixed gear 332 to rotate, and through the meshing of the fixed gear 332 and the rack 331, the limiting half-cylinder 33 slides on the fixed frame 32.

[0028] To ensure the stability of the test tube clamping and fixation while avoiding hard contact between the limiting half-cylinder 33 and the test tube, which could damage the test tube structure, the fixing frame 32 is slidably connected to a slide block 34. The slide block 34 is connected to the sliding limiting half-cylinder 33 through an elastic buffer component. The sliding direction of the slide block 34 is collinear with the sliding direction of the corresponding limiting half-cylinder 33. The rack 331 is provided on the slide block 34.

[0029] With the above settings, under the premise that the limiting half-cylinder 33 is clamped to the test tube, the elastic buffer component is used for elastic buffering to avoid irreversible deformation of the test tube caused by hard contact.

[0030] To further explain the specific structure of the elastic buffer assembly, the elastic buffer assembly includes multiple spring slide rods 35, the two ends of which are connected to the slide block 34 and the limiting half cylinder 33 respectively, so that the slide block 34 and the limiting half cylinder 33 are elastically spaced apart; the sliding direction of the spring slide rods 35 is parallel to that of the slide block 34.

[0031] It should be noted that the aforementioned spring slide rod 35 refers to a rod-shaped component fitted with a spring. One end of the rod is fixedly connected to the slide block 34, and the other end is slidably fitted with the limiting half-cylinder 33. The spring is clamped between the slide block 34 and the limiting half-cylinder 33.

[0032] To directly avoid hard contact between the fixed groove 30 and the test tube, the rotating roller 31 is rolled on the groove wall of the fixed groove 30; when the two limiting half cylinders 33 are engaged, all the rotating rollers 31 are arranged parallel to the test tube located in the fixed groove 30 and are in contact with the side wall line of the test tube located in the fixed groove 30.

[0033] With the above settings, the rotating roller 31 replaces the groove wall of the fixed groove 30 to contact the side wall of the test tube. The roller surface of the rotating roller 31 can be covered with a rubber layer, which can not only avoid hard contact, but also increase friction and facilitate the rotation of the test tube.

[0034] To facilitate tube removal, the top and bottom ends of the fixing groove 30 are both through the fixing mechanism.

[0035] With the above settings, after labeling is completed, the two limiting half-cylinders 33 are moved a certain distance apart, and the test tubes can automatically fall from the bottom of the fixing groove 30. Simply place a tray directly below the fixing groove 30 to receive the test tubes.

[0036] To guide the insertion of the test tube, each of the limiting half-cylinders 33 is provided with multiple edge-finding rods 36 horizontally. The distance between the edge-finding rods 36 and the rotating rollers 31 provided on the side wall of the corresponding limiting half-cylinder 33 is slightly larger than the outer diameter of the test tube. The top of the other limiting half-cylinder 33 is provided with a fifth detector 37, which is used to detect whether there is a test tube in the fixing groove 30.

[0037] With the above settings, the test tube is inserted between the limiting half-cylinder 33 and the edge-finding stop bar 36, and then the two limiting half-cylinders 33 are controlled to move closer to each other and clamp the test tube.

[0038] To further explain the specific structure of the main printing mechanism, the main printing mechanism includes a main unit 38, a main printer 381, and a main printing paper 382; the main printer 381 and the main printing paper 382 are both located on the main unit 38, the main printer 381 is provided with a paper inlet and a label outlet, and the main printing paper 382 enters from the paper inlet and exits from the label outlet.

[0039] In order to print classification labels, the above-mentioned test tube labeling device also includes a secondary printer 39, which is used to print classification labels.

[0040] With the above settings, the secondary printer 39 can be used to print classification labels separately, and the printed classification labels can be directly dropped into the tray below.

[0041] It should be noted that the aforementioned secondary printer 39 can be any type of label printer in the prior art.

[0042] The above description is only a preferred embodiment of the present utility model and does not limit the implementation method and protection scope of the present utility model. Those skilled in the art should realize that all solutions obtained by equivalent substitutions and obvious changes made based on the description and illustrations of the present utility model should be included within the protection scope of the present utility model.
