Description

Technical Field

[0001] This utility model relates to the field of packaging technology for traditional Chinese medicine liquids, and in particular to a packaging material roll detection structure for an automatic labeling and packaging machine for traditional Chinese medicine. Background Technology

[0002] Traditional Chinese medicine packaging encompasses processes such as herbal pretreatment, measurement, and encapsulation. While traditionally, manual paper wrapping was common, automated packaging machines are now widely used, enabling integrated operations such as weighing, filling, sealing, and labeling. For example, herbal medicine factories use machines to mass-produce herbs like Astragalus membranaceus, and hospital pharmacies customize packaging for granules. This ensures accurate dosage and allows for labeling with information such as the herbal name, specifications, and production date, facilitating storage and use.

[0003] The automatic labeling and packaging machine for traditional Chinese medicine can automatically complete processes such as weighing, filling, labeling, and sealing, with high efficiency and accurate label information. It is suitable for bulk packaging of medicinal materials such as astragalus and codonopsis in Chinese herbal medicine processing plants, as well as for boxed labeling of pills and tablets in Chinese patent medicine plants. It can also be used for personalized packaging of Chinese herbal medicine granules in hospital pharmacies, meeting the automated packaging needs of different scenarios.

[0004] In existing technologies, some packaging machines require manual detection and replacement after the packaging roll is used up. If the manual detection is not timely, the medicine liquid will continue to be fed, causing the medicine liquid to drip, thus wasting the medicine liquid and affecting the cleanliness of the working environment. To address this issue, a packaging roll detection structure for an automatic labeling and packaging machine for traditional Chinese medicine is proposed. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a packaging material roll detection structure for an automatic labeling and packaging machine for traditional Chinese medicine. It aims to improve the problem in some existing packaging machines that require manual detection and replacement after the packaging roll is used up. If the manual detection is not timely, the medicine liquid will continue to be fed, resulting in the medicine liquid dripping.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A packaging material roll detection structure for an automatic labeling and packaging machine for traditional Chinese medicine includes a drive motor, a drive rod fixedly connected to the drive end of the drive motor, a fixed plate fixedly connected to the outer wall of the drive rod, a sensing plate fixedly connected to the outer wall of the fixed plate, a fixing screw threadedly connected to the inner wall of the sensing plate, a fixing screw threadedly connected to the outer wall of the fixing screw to the inner wall of the fixed plate, a mounting shaft rotatably connected to the outer wall of the drive rod, a mounting bracket detachably connected to the top of the mounting shaft, and a sensor fixedly connected to the inner wall of the mounting bracket.

[0008] As a further description of the above technical solution:

[0009] A mounting plate is fixedly connected to the top of the mounting shaft, and a mounting column is detachably connected to the inner wall of the mounting plate.

[0010] As a further description of the above technical solution:

[0011] The inner wall of the mounting column is fixedly connected with multiple limiting columns, and the outer wall of each of the multiple limiting columns is fitted with a return spring.

[0012] As a further description of the above technical solution:

[0013] Each of the multiple reset springs has a fixing block fixedly connected to its top, and the outer walls of the multiple fixing blocks are in contact with the outer wall of the mounting bracket.

[0014] As a further description of the above technical solution:

[0015] A wire is fixedly connected to the inner wall of the sensor, and an alarm module is fixedly connected to one end of the wire.

[0016] As a further description of the above technical solution:

[0017] The outer wall of the mounting plate is detachably connected to the outer wall of the mounting frame, and the outer wall of the mounting column is detachably connected to the inner wall of the mounting frame.

[0018] This utility model has the following beneficial effects:

[0019] 1. In this utility model, when the packaging roll is used up, the drive motor will stop driving the drive rod to rotate, thereby stopping the rotation of the fixed plate and causing the sensing plate to stop rotating as well. When the sensor detects that the sensing plate is no longer rotating, it determines that the fixed plate is no longer rotating. Therefore, the sensor will transmit the signal to the alarm through the wire. At this time, the alarm will sound an alarm to remind the staff to replace the packaging roll, thus preventing the waste of medicine caused by the packaging roll stopping while the feeding is still in progress and the staff not notifying in time.

[0020] 2. In this utility model, when the sensor needs to be disassembled for maintenance or replacement, the fixing block is pressed. The pressing of the fixing block will cause it to retract into the inner wall of the mounting column under the action of the return spring. Then, the mounting column can be pulled out to remove the mounting bracket and the sensor. When installation is required, the mounting column is inserted, and the return spring will control the fixing block to pop out and lock onto the outer wall of the mounting bracket, thereby achieving installation and fixation.

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0028] Reference Figures 1 to 3 This utility model provides an embodiment of a packaging material roll detection structure for an automatic labeling and packaging machine for traditional Chinese medicine, including a drive motor 1. A drive rod 2 is fixedly connected to the drive end of the drive motor 1. The drive rod 2 can rotate under the drive of the drive motor 1 to transmit power. A fixed disk 14 is fixedly connected to the outer wall of the drive rod 2. The fixed disk 14 rotates with the drive rod 2 to drive the sensor 6 to move. The sensor 6 is fixedly connected to the outer wall of the fixed disk 14. When the sensor 6 rotates with the fixed disk 14, its protrusions and grooves will alternate at the sensor 5 to trigger detection. A fixing screw 7 is threadedly connected to the inner wall of the sensor 6. The fixing screw 7 is used to firmly install the sensor 6 on the fixed disk 14.

[0029] The outer wall of the fixing screw 7 is threaded to the inner wall of the fixing plate 14. The threaded connection enables the sensor 6 to be detachably fixed to the fixing plate 14. The outer wall of the drive rod 2 is rotatably connected to the mounting shaft 15, which provides rotational support for the drive rod 2. The top of the mounting shaft 15 is detachably connected to the mounting bracket 4, which is used to install the sensor 5 and fix its position. The inner wall of the mounting bracket 4 is fixedly connected to the sensor 5, which is used to detect the rotation state of the sensor 6 to determine whether the packaging roll is used up. The top of the mounting shaft 15 is fixedly connected to the mounting plate 3, which is used to connect the mounting column 13 and provide an installation base. The inner wall of the mounting plate 3 is detachably connected to the mounting column 13, which can be inserted into the mounting bracket 4 to install and fix the sensor 5.

[0030] Reference Figures 2 to 4 Multiple limiting posts 12 are fixedly connected to the inner wall of the mounting post 13. The limiting posts 12 are used to limit the movement trajectory of the reset spring 11 to prevent displacement. The outer walls of the multiple limiting posts 12 are all fitted with reset springs 11. The reset springs 11 are compressed when the fixing block 10 is pressed and reset when released to push the fixing block 10 out. The tops of the multiple reset springs 11 are fixedly connected with fixing blocks 10. Under the action of the reset springs 11, the fixing blocks 10 can lock the outer wall of the mounting frame 4 to fix the mounting post 13. The outer walls of the multiple fixing blocks 10 are in contact with the outer wall of the mounting frame 4. In the contact state, the fixing blocks 10 can limit and fix the mounting post 13.

[0031] A wire 8 is fixedly connected to the inner wall of the sensor 5. The wire 8 is used to transmit the signal detected by the sensor 5. One end of the wire 8 is fixedly connected to an alarm module 9. After receiving the signal from the sensor 5, the alarm module 9 issues an alarm to remind the staff. The outer wall of the mounting plate 3 is detachably connected to the outer wall of the mounting frame 4. The mounting plate 3 and the mounting frame 4 are fixed and disassembled through the detachable connection. The outer wall of the mounting column 13 is detachably connected to the inner wall of the mounting frame 4. The mounting column 13 is installed and disassembled in the mounting frame 4 through insertion and pop-out.

[0032] Working principle: When the packaging machine is used to automatically label traditional Chinese medicine, the drive rod 2 drives the fixed plate 14 to rotate. The rotation of the fixed plate 14 drives the sensor plate 6 to rotate. The protrusions and grooves between the sensor plates 6 alternate continuously at the detection point of the sensor 5. When the packaging roll is used up, the drive motor 1 will stop driving the drive rod 2 to rotate, and then the fixed plate 14 will also stop rotating. Since the fixed plate 14 stops rotating, the sensor plate 6 will also stop rotating. When the sensor 5 detects that the sensor plate 6 is no longer rotating, it determines that the fixed plate 14 is no longer rotating. Therefore, the sensor 5 will transmit a signal to the alarm through the wire 8. The alarm will then sound to remind the staff to replace the packaging roll, preventing the waste of medicine due to the packaging roll stopping while the feeding is still in progress and the staff not notifying in time.

[0033] When sensor 5 needs to be disassembled for inspection or replacement, press the fixing block 10. The pressing of the fixing block 10 will cause it to retract into the inner wall of the mounting post 13 under the action of the return spring 11. Then, pull out the mounting post 13 to remove the mounting bracket 4 and sensor 5. When installation is required, insert the mounting post 13. Then, the return spring 11 will control the fixing block 10 to pop out and lock into the outer wall of the mounting bracket 4, thereby achieving installation and fixation.

[0034] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
