On the other hand, the labeling device has certain limitations on the specifications of medicine bottles and cannot be compatible with various sizes of medicine bottles, which cannot meet the practical requirements of various nuclear medicine preparation manufacturers. Finally, it cannot add customized functions based on changes in the usage environment, such as changes in transmission structure and product materials. Summary of the Invention

[0005] Preferably, the acrylic pressure plate is equipped with a slotted locking handle for locking, which is axially fixed by locking screws and has a rotating screw to adjust the rotational force, facilitating manual operation while saving installation space. The transparent acrylic pressure plate above the label paper allows observation of the label paper's usage and installation position through a viewing window.

[0006] Preferably, the limiting sleeve is made of polyurethane, which has a certain degree of flexibility and rigidity and can be adjusted according to the size of the paper to accommodate different label paper sizes.

[0007] Preferably, in use, the bottle is placed between two driven rollers, the cylinder pushes the driven rollers, the bottle moves towards and contacts the driving roller, and the driving roller drives the bottle to rotate.

[0008] Preferably, the locking shaft is an eccentric shaft; the second surface of the rotating shaft is sandblasted to increase the friction between the paper and the rotating shaft.

[0009] Preferably, the traction module further includes a pin for limiting the rotation shaft of the traction module.

[0013] To make this utility model more apparent and understandable, preferred embodiments are described in detail below with reference to the accompanying drawings.

[0014] like Figure 1-2 As shown, this utility model provides a small automatic inkjet labeling device for nuclear-grade environments, which includes a label paper installation module, a label paper guiding module, a label paper position detection sensor 7, a label peeling module, a labeling module, a traction module, and a waste paper collection module.

[0015] The label mounting module includes a rotating shaft for rotating the label, and an acrylic pressure plate 1 for limiting the label at the top of the rotating shaft. A locking handle 3 is mounted on the acrylic pressure plate 1 for locking.

[0016] The label paper guiding module includes a rotating shaft 4 for rotating and guiding the label paper, and limiting sleeves 5 are provided at both ends of the rotating shaft 4. The limiting sleeves 5 are made of polyurethane.

[0018] The labeling module includes a drive roller 12, a pair of driven rollers 15, and a cylinder 14. The drive roller 12 has a rotating shaft 13 driven by a motor. The driven rollers 15 are connected to the output end of the cylinder 14. In use, the bottle is placed between the two driven rollers 15. The cylinder 14 pushes the driven rollers 15, and the bottle moves towards and contacts the drive roller 12. The drive roller 12 then rotates the bottle.

[0019] The traction module includes a locking shaft 8 and a rotating shaft 9 for pulling the bottom paper. The locking shaft 8 is an eccentric shaft; the surface of the rotating shaft 9 is sandblasted.

[0020] The waste paper collection module includes a rotating shaft for winding up the bottom paper and a pin for limiting the rotating shaft.

[0021] Example

[0022] In this embodiment, the label paper is advanced by a traction mechanism, and the label is separated by a peeling mechanism. After the separated label comes into contact with the bottle, the bottle's rotational force drives the label to rotate, thus realizing the labeling function. The inkjet printer is installed in the middle of the equipment to realize real-time marking. The driven roller is connected to the cylinder and is distributed in a V-shape. When the bottle is in position, the cylinder lifts the bottle and drives it to contact the active roller, thereby driving the bottle to rotate. The V-shape can realize the positioning of the bottle, and the gap left in the middle can realize the labeling function of medicine bottles of different sizes.

[0023] The above-mentioned equipment has a compact overall structure, with the transmission structure installed at the bottom and the functional components installed at the top, adopting an up-and-down layout that greatly reduces the installation size of the equipment. The equipment's structure is independently designed and can be adjusted according to different customer needs to meet their usage requirements.

[0024] As a preferred technical solution, in this embodiment, the label paper is made of transparent PVC backing paper and is white. When the label paper passes through the sensor, the sensor cannot receive the transmitted light due to the obstruction of the label, and the sensor has no signal. When it passes through the transparent gap, the light can pass through the transparent backing paper and hit the transmitting end. The sensor receives the signal, and the control system controls the motor to stop rotating, thus completing the labeling of a bottle.

[0025] As a preferred technical solution, in this embodiment, the single-piece locking handle is made of carbon steel with a painted end, which has high strength. The single-piece structure reduces the installation space and facilitates manual operation to complete the replacement of the label.

[0026] As a preferred technical solution, in this embodiment, all rotating shafts are made of 30Cr13 material with hard chrome plating, which greatly increases the wear resistance of the shafts. Bearings are installed at both ends of the shafts, making the rotation smoother and without jamming.

[0027] As a preferred technical solution, in this embodiment, the limiting sleeve is made of polyurethane, with a circular structure in appearance, an inner diameter smaller than the shaft diameter, and an opening of 3mm at one end, which can allow it to stop at any position in the axial direction. In addition, the polyurethane material has a certain degree of elasticity and will not damage the label paper.

[0028] As a preferred technical solution, in this embodiment, the pin is U-shaped and used to fix waste paper. It is interference-fitted with the mounting hole of the roll, and can directly fix the waste paper after insertion. It is simple to operate and easy to process.

[0029] As a preferred technical solution, in this embodiment, the label peeling plate is made of 304 stainless steel, and the head is made of small V-shape to ensure the separation of the label from the backing paper. Scale lines are used on the top of the label peeling plate to ensure that the label is installed in basically the same position each time, preventing the label paper error after human installation from affecting the labeling accuracy.

[0030] As a preferred technical solution, in this embodiment, the active roller is made of polyurethane material, which has a certain amount of deformability to prevent excessive extrusion pressure from damaging the bottle itself. On the other hand, the friction of the polyurethane surface is greater than that of other plastic materials, ensuring that the bottle and the active roller can rotate synchronously.
