Description
Technical Field
[0001] This utility model relates to the field of labeling equipment technology, specifically a fully automatic labeling device for round bottles adapted to physiological seawater nasal sprays. Background Technology
[0002] In the field of medical device and daily care product manufacturing, physiological saline nasal sprays are a common product used for nasal cleaning and care. Their packaging mostly adopts a round bottle structure, and the bottle body must be affixed with a label containing product information, instructions for use, production batch number, etc. The accuracy and standardization of label affixing directly affect the product's appearance quality and market acceptance.
[0003] Traditional equipment relies solely on simple conveyor belts or tracks for transporting round bottles, lacking specialized alignment and guidance structures. Because the bottles are cylindrical, they are prone to rolling and shifting during transport due to vibration and uneven friction, leading to deviations when they reach the labeling station and consequently, skewed or misaligned labels. Therefore, those skilled in the art have provided a fully automated labeling device for round bottles adapted to physiological saline nasal sprays to address the problems mentioned in the background section. Utility Model Content
[0004] The purpose of this invention is to provide a fully automatic labeling device for round bottles adapted to physiological saline nasal sprayers, so as to solve the problems mentioned in the background art.
[0005] To achieve the above objectives, this utility model provides the following technical solution:
[0006] A fully automatic labeling device for round bottles adapted to physiological saline nasal sprays includes a work frame, a positioning structure, and a labeling structure. The work frame is characterized by having a conveyor belt inside, with several limiting strips fixedly connected to the outer surface of the conveyor belt, and anti-slip blocks fixedly connected to the limiting strips. A second motor is installed on the outer wall of the work frame, and the output end of the second motor is connected to the conveyor belt. Positioning structures are installed on both inner side walls of the work frame. A release film roller is installed inside the work frame, and a label unwinding roller is installed inside the work frame on one side of the release film roller. Two guide rollers are installed inside the work frame on the side of the label unwinding roller away from the release film roller, and the labeling structure is installed above the two guide rollers.
[0007] As a further embodiment of this utility model: the positioning structure includes a positioning sleeve, a threaded rod, a connecting sleeve, a movable plate, a rubber block, and a threaded sleeve. The positioning sleeve is fixedly connected to both inner side walls of the work frame. The threaded rod is rotatably connected to both inner side walls of the work frame and inside the positioning sleeve. The two threaded rods are fixedly connected to a first synchronous wheel through the work frame at opposite ends.
[0008] As a further improvement of this utility model: a first motor is provided on both outer side walls of the work frame, and the output end of the first motor is fixedly connected to the first synchronous pulley, and a threaded sleeve is threadedly connected to the threaded rod.
[0009] As a further embodiment of this utility model: a connecting sleeve is fixedly connected to one end of each of the two threaded sleeves, a movable plate is fixedly connected to one end of each of the two connecting sleeves, and a rubber block is fixedly connected to one end of each of the two movable plates.
[0010] As a further embodiment of this utility model: the labeling structure includes a rotating shaft, a disc, a protruding column, a limiting sleeve, a vertical plate, a movable sleeve, and a labeling block. The two inner side walls of the work frame are rotatably connected to rotating shafts. The two rotating shafts are respectively connected to a second synchronous wheel through the work frame at opposite ends. A synchronous belt is provided between the first synchronous wheel and the second synchronous wheel.
[0011] As a further embodiment of this utility model: a disc is fixedly connected to one end of each of the two rotating shafts, and a protruding column is fixedly connected to one end of each of the two discs; a limit sleeve is fixedly connected to the two inner side walls of the work frame, and a vertical plate is slidably connected inside the limit sleeve.
[0012] As a further embodiment of this utility model: a movable sleeve is fixedly connected to the top of the vertical plate through the limiting sleeve, and the protruding column is located inside the movable sleeve; a labeling block is fixedly connected to the bottom of the vertical plate through the limiting sleeve, and the labeling block is located between the two guide rollers.
[0013] As a further improvement of this utility model: a label recycling roller is provided inside the work frame and on the side of the guide roller away from the label unwinding roller. Both the release film roller and the label recycling roller are connected to an external drive motor. A sensor is provided on one inner side wall of the work frame.
[0014] Compared with the prior art, the beneficial effects of this utility model are:
[0015] 1. This device completes the positioning operation of the round bottle to be labeled through the setting of the positioning structure. When the sensor detects that the round bottle to be labeled has reached the positioning area, the sensor on the inner wall of the work frame will detect the round bottle and send a signal to shut down the second motor and start the first motor to drive the first synchronous wheel and the threaded rod to rotate. This will drive the connecting sleeve, the movable plate and the rubber block to move closer to the round bottle. The rubber block is elastic, which can not only fit tightly against the surface of the round bottle, but also avoid scratching the plastic bottle. Finally, the round bottle is centered in the labeling station, ensuring that the bottle does not shake and the label position is accurate during labeling.
[0016] 2. This device completes the labeling operation through the setting of the labeling structure. The first synchronous pulley, the synchronous belt and the second synchronous pulley work together to drive the two rotating shafts and the disc to rotate, which in turn drives the movable sleeve and the vertical plate to move downward. At this time, the vertical plate will drive the labeling block to move downward. The labeling block accurately presses the label conveyed by the guide roller onto the designated position of the round bottle. After the labeling is completed, the vertical plate drives the labeling block to return to its original position, waiting for the next round bottle to arrive before repeating the labeling action.
[0017] 3. This device uses a second motor to drive the conveyor belt, which transports the round bottles to be labeled to the work area. The limiting strips on the surface of the conveyor belt divide the round bottles into independent units for limiting operation to prevent them from colliding with each other. The anti-slip strips increase the friction between the round bottles and the conveyor belt, avoiding positional deviation caused by vibration during the transportation process, and ensuring that the round bottles enter the labeling station in a stable posture.

Detailed Implementation
[0024] 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.
[0025] Example 1: Refer to Figure 1-4 This embodiment provides a fully automatic labeling device for round bottles adapted to physiological saline nasal sprays, including a work frame 1, a positioning structure, and a labeling structure. The work frame 1 is characterized by having a conveyor belt 2 inside, with several limiting strips 3 fixedly connected to the outer surface of the conveyor belt 2, and anti-slip blocks 4 fixedly connected to the limiting strips 3. A second motor 25 is installed on the outer wall of the work frame 1, and the output end of the second motor 25 is connected to the conveyor belt 2. Positioning structures are installed on both inner side walls of the work frame 1. The work frame 1 is internally equipped with... A release film roller 13 is provided. Inside the work frame 1 and on one side of the release film roller 13, a label unwinding roller 14 is provided. Inside the work frame 1 and on the side of the label unwinding roller 14 away from the release film roller 13, two guide rollers 23 are provided. A labeling structure is provided above the two guide rollers 23. Inside the work frame 1 and on the side of the guide rollers 23 away from the label unwinding roller 14, a label recycling roller 24 is provided. Both the release film roller 13 and the label recycling roller 24 are connected to an external drive motor. A sensor 26 is provided on one inner side wall of the work frame 1.
[0026] The positioning structure includes a positioning sleeve 5, a threaded rod 6, a connecting sleeve 7, a movable plate 8, a rubber block 9, and a threaded sleeve 27. The positioning sleeve 5 is fixedly connected to both inner walls of the work frame 1. The threaded rod 6 is rotatably connected to both inner walls of the work frame 1 and inside the positioning sleeve 5. The two threaded rods 6 are fixedly connected to the first synchronous wheel 10 through the work frame 1 at opposite ends.
[0027] The work frame 1 is equipped with a first motor 11 on both outer side walls, and the output end of the first motor 11 is fixedly connected to the first synchronous pulley 10. The threaded rod 6 is threaded with a threaded sleeve 27. The two threaded sleeves 27 are fixedly connected to a connecting sleeve 7 at one end close to each other. The two connecting sleeves 7 are fixedly connected to a movable plate 8 at one end close to each other. The two movable plates 8 are fixedly connected to a rubber block 9 at one end close to each other.
[0028] In this implementation, the label is unloaded onto the roller, and the second motor 25 drives the conveyor belt 2 to transport the round bottles to be labeled to the work area. The limiting strips 3 on the surface of the conveyor belt divide the round bottles into independent units for limiting operation to prevent mutual collision. The anti-slip strips 4 increase the friction between the round bottles and the conveyor belt to avoid positional deviation caused by vibration during transportation, ensuring that the round bottles enter the labeling station in a stable posture. When the sensor detects that the round bottle to be labeled has reached the positioning area, the sensor 26 on the inner wall of the work frame 1 will detect the round bottle and send a signal to shut off the second motor 25. At the same time, the first motors 11 on both sides of the work frame will start to drive the first synchronous wheel 10 to rotate, which in turn drives the threaded rod 6 in the positioning sleeve 5 to rotate. The threaded rod 6 and the threaded sleeve 27 convert the rotational motion into linear motion through thread transmission, so that the connecting sleeve 7 and the movable plate 8 drive the rubber block 9 to move closer to the round bottle. The rubber block 9 is elastic, which can not only fit tightly to the surface of the round bottle, but also avoid scratching the plastic bottle body. Finally, the round bottle is centered in the labeling station to ensure that the bottle is properly positioned during labeling. Without shaking and with the label accurately positioned, the rolled label material is mounted on the label unwinding roller 14. At this point, the label roll has a composite structure of a label layer and a release film layer. The free end of the release film needs to be pre-drawn to the release film roller 13 and the label recovery roller 24. The release film roller 13 assists in peeling off the label, and the label recovery roller 24 recovers the peeled release film. Both the release film roller 13 and the label recovery roller 24 are driven by an external motor to provide power for the roll material transport. The label roll is fed from the label unwinding roller 14... After release, it is first slightly tilted and conveyed towards the labeling structure, passing around the two guide rollers 23 in sequence, and then fixed on the label recycling roller 24. The two guide rollers 23 are distributed on the left and right to guide the label roll to the labeling station directly below the labeling block 21, ensuring that the label conveying path is stable and flat. After the label roll passes the guide rollers 23, the label layer and the release film layer begin to separate. The peeled label layer continues to be conveyed forward and is finally conveyed to the bottom of the labeling block 21, waiting to be pasted onto the surface of the round bottle when the labeling block presses down.
[0029] Example 2: Refer to Figure 1-5 This embodiment is based on the previous embodiment, but differs from the previous embodiment in that the labeling structure includes a rotating shaft 15, a disc 16, a protruding column 17, a limiting sleeve 18, a vertical plate 19, a movable sleeve 20, and a labeling block 21. The two inner side walls of the work frame 1 are rotatably connected to the rotating shaft 15. The two rotating shafts 15 are fixedly connected to the second synchronous wheel 22 through the work frame 1 at opposite ends. A synchronous belt 12 is provided between the first synchronous wheel 10 and the second synchronous wheel 22.
[0030] Two rotating shafts 15 are fixedly connected to a disc 16 at one end close to each other, and two discs 16 are fixedly connected to a protruding column 17 at one end close to each other. Limiting sleeves 18 are fixedly connected to the two inner side walls of the work frame 1, and vertical plates 19 are slidably connected inside the limiting sleeves 18.
[0031] The top end of the vertical plate 19 is fixedly connected to the movable sleeve 20 through the limiting sleeve 18, and the protruding column 17 is located inside the movable sleeve 20. The bottom end of the vertical plate 19 is fixedly connected to the labeling block 21 through the limiting sleeve 18, and the labeling block 21 is located between the two guide rollers 23.
[0032] In this embodiment, while the first synchronous pulley 10 rotates, the second synchronous pulley 22 rotates synchronously through the transmission action of the synchronous belt 12, thereby driving the rotating shaft 15, which is fixedly connected to the second synchronous pulley 22, to rotate. The rotation of the rotating shaft 15 drives the disc 16 to perform circumferential motion. The protruding post 17 on the disc 16 is embedded in the movable sleeve 20 at the top of the vertical plate 19. As the disc 16 rotates, the protruding post 17 slides in the movable sleeve 20 and pushes the vertical plate 19 to move up and down along the limiting sleeve 18. The limiting sleeve 18 guides and limits the vertical plate 19 to ensure its stable movement trajectory. The label unwinding roller 14 continuously releases the roll material with the label. After being guided by the two guide rollers 23, the roll material... The label is precisely conveyed to the labeling station below the labeling block 21. During this process, the release film roller 13 works in conjunction with the peeling of the label to separate the label from the release film. The separated release film is then collected and wound by the label recycling roller 24. The release film roller 13 and the label recycling roller 24 are driven by an external drive motor. When the round bottle is positioned and arrives at the labeling station with the conveyor belt 2, the sensor 26 will detect that other round bottles have arrived at the positioning area and send a signal. At this time, the vertical plate 19 will drive the labeling block 21 to move downward. The labeling block 21 will accurately press the label conveyed by the guide roller 23 onto the designated position of the round bottle. After the labeling is completed, the vertical plate 19 will drive the labeling block 21 to reset upward, waiting for the next round bottle to arrive before repeating the labeling action.
