Description

Technical Field

[0001] This invention relates to the technical field of labeling machines, and in particular to a self-adhesive round bottle labeling machine. Background Technology

[0002] A self-adhesive round bottle labeling machine is a device that affixes self-adhesive labels to the circumferential surface of round bottles. Various self-adhesive round bottle labeling machines are disclosed in the prior art. For example, Chinese invention patent CN111572929B discloses a round bottle labeling machine that includes a transport channel, side guards, a rotating body, an application pressing body, and a limiting plate. The side guards are welded to the upper surface of the transport channel, and the rotating body is installed on the side surface of the application pressing body. The bottle is placed between the application pressing body and the limiting plate. As the round bottle rotates past the application pressing body, the label moves with the bottle body to the fixed block. Extending the overall fixing force allows the connecting part to have a force point, extending the area of ​​the reverse force application at the connecting part. The other end will drag the swing angle and tilt it in the opposite direction, pressing it with an arc on both sides, so that it can be smoothly attached to the protrusion. The solid at the rear end fixes the force point of the swing edge, and the swing edge will be stressed through the rubber strip. The distance between the elastic balls will limit the overall bending force, which can limit the space range when the connecting part bends. When the round bottle is in contact, it can give it a certain fixed bending angle, allowing it to better push the next step.

[0003] However, the existing labeling machine mentioned above, like other labeling machines, only has one labeling station, and this single labeling station is not modularly designed, making it inconvenient to expand to multiple stations. In the process of labeling round bottles, positioning and labeling the round bottles at the labeling station takes a long time. The working method of only setting up one labeling station and labeling only one round bottle at a time is not conducive to improving work efficiency. Summary of the Invention

[0004] To solve the above-mentioned technical problems, the present invention provides a self-adhesive round bottle labeling machine that can achieve modular expansion of different numbers of labeling stations, automatically label multiple round bottles at one time, and improve work efficiency.

[0005] The self-adhesive round bottle labeling machine of the present invention includes a first roll frame and a second roll frame mounted on a main platform. The first roll frame is used to load the roll of self-adhesive labeling film, and the second roll frame is used to wind up the labeling film. It also includes: a conveyor belt mechanism mounted on the side of the main platform for conveying round bottles; a movable mounting and positioning roller mechanism is mounted on the side of the frame of the conveyor belt mechanism; the positioning roller mechanism is arranged opposite to the main platform; the positioning roller mechanism is provided with multiple positioning vertical roller groups for rolling and positioning the round bottles; the fixed end of a push cylinder is mounted on the frame of the conveyor belt mechanism; the piston rod of the push cylinder is drivenly connected to the positioning roller mechanism; a drive module mounted on the main platform, the drive module having a circumferential rotation output end and an angle control output end; and multiple labeling modules mounted on the main platform, the number of labeling modules being the same as the number of positioning vertical roller groups, the multiple labeling modules being arranged opposite to the multiple positioning vertical roller groups, and the components of the multiple labeling modules that roll the round bottles being drivenly connected to the circumferential rotation output end of the drive module. Multiple labeling module state switching components are connected to the angle control output of the drive module. The self-adhesive label film output from the first roll frame passes through the state switching components of multiple labeling modules in sequence and is then wound onto the second roll frame. The state switching components of multiple labeling modules can switch between the conveying state and the labeling state of the self-adhesive label film. The main platform is also equipped with necessary guide roller assemblies and tensioning assemblies for the self-adhesive label film, as well as drive mechanisms for the first and second roll frames, to ensure that the self-adhesive label film is conveyed rhythmically, stably, and reliably. The above is existing technology and will not be described in detail here. According to actual work needs, an appropriate number of labeling modules and the same number of positioning roller groups are set. The labeling modules are modularly designed and can be easily installed on the main platform to realize multiple labeling stations evenly arranged along the main platform. The spacing of the self-adhesive labels on the self-adhesive label film is optimized and matched with the spacing of multiple labeling modules so that multiple self-adhesive labels can match the multiple labeling work positions.During operation, a new reel is loaded onto reel holder one. After the self-adhesive labeling tape is pulled out, it passes sequentially around the guide roller assembly and tensioning assembly, and then sequentially around the state switching components of multiple labeling modules. The state switching components of multiple labeling modules switch to the labeling state. The conveyor belt mechanism operates to transport multiple upright round bottles backward, quantitatively transporting the same number of round bottles as the labeling modules. When multiple round bottles reach the positioning roller mechanism, the push cylinder action pushes the positioning roller mechanism towards the main platform, causing the multiple positioning vertical roller groups of the positioning roller mechanism to roll and press the multiple round bottles onto the rolling round bottle components of the multiple labeling modules. The drive module operates to drive the rolling round bottle components of the multiple labeling modules to rotate synchronously, causing the multiple round bottles to rotate. At the same time, reel holder one and reel holder two cooperate to transport the self-adhesive labeling tape, thereby causing multiple self-adhesive labels to be simultaneously applied to multiple round bottles. On the outer wall, the push cylinder resets, causing the positioning roller mechanism to retract and release multiple round bottles. The conveyor belt mechanism continues to transport these bottles backward, while simultaneously transporting the next batch of bottles to the positioning roller mechanism. During this process, the state switching components of multiple labeling modules switch to the self-adhesive label film conveying state. Roller frame one and roller frame two work together to quickly convey the length of multiple labels on the self-adhesive label film, ensuring that each labeling module corresponds to a new label in turn. The state switching components of multiple labeling modules then switch to the labeling state, preparing for the next labeling cycle. Compared to existing technologies, this method achieves modular expansion of different numbers of labeling stations by setting multiple labeling modules, enabling simultaneous automatic labeling of multiple round bottles at multiple stations. This offers greater applicability and significantly reduces the average labeling time for round bottles compared to traditional single-station labeling, thereby improving work efficiency.

[0006] Preferably, the labeling module includes: a base plate detachably mounted on the main platform; a drive roller rotatably mounted on the base plate via a vertical shaft; the drive roller is used to roll the round bottle; an input guide roller rotatably mounted on the base plate via a vertical shaft; the input guide roller is located behind the drive roller and is used to guide the input portion of the self-adhesive labeling film; and an output guide roller rotatably mounted on the base plate via a vertical shaft; the output guide roller is located to the side of the drive roller and is used to guide the output portion of the self-adhesive labeling film. A corner plate is mounted on a bracket. On the rotating shaft three, the angled plate is located on the side of the output guide roller. The angled plate is used for peeling and applying self-adhesive label film. Multiple base plates are evenly installed on the main platform by bolts. The drive roller is a component for rolling the round bottle. The output guide roller and the angled plate are state switching components. When conveying self-adhesive label film, the rotating shaft three rotates a certain angle, causing the angled plate to rotate to the side of the output guide roller facing the main platform. The end of the self-adhesive label film output from the roll frame one is guided by the input guide roller to the side facing the main platform and enters the labeling module. After being guided by the output guide roller towards one side of the conveyor belt mechanism, the labeling module outputs the labeling film, allowing the end of the self-adhesive label film to enter the next labeling module or be wound onto the reel holder two. At this time, the reel holder one and the reel holder two cooperate to convey the self-adhesive label film, so that multiple self-adhesive labels reach between the input guide roller and the output guide roller on the multiple base plates one respectively. At this time, the rotating shaft three reverses and resets, so that the angle plate cuts into the inside of the conveyed self-adhesive label film on the output guide roller, and the edge of the angle plate makes the self-adhesive label film sharply angled. An angled plate is pressed against the side wall of the drive roller. The acute angle causes the edge of the self-adhesive label to detach from the self-adhesive label film. At this time, the round bottle is rolled on the drive roller, causing the edge of the self-adhesive label to stick to the outer wall of the round bottle. The drive roller drives the round bottle to roll, and at the same time, it cooperates with the conveying of the self-adhesive label film, so that the self-adhesive label detaches from the film and is automatically attached to the round bottle. The above actions are repeated for continuous automatic labeling. The specific working principle and working effect of the angle plate and the acute angle of the self-adhesive label film are existing technologies and will not be described in detail here.

[0007] Preferably, the system further includes multiple gears 1 concentrically mounted on multiple rotating shafts 1, each gear 1 meshing with multiple gears 2, each gear 2 rotatably mounted on multiple base plates 1 via multiple rotating shafts 4, each rotating shaft 4 concentrically mounted with multiple driven wheels 1, the driven wheels 1 being sequentially connected and connected to the circumferential rotation output end of the drive module; and multiple gears 3 concentrically mounted on multiple rotating shafts 3, each gear 3 meshing with multiple gears 4, each gear 4 rotatably mounted on multiple base plates 1 via multiple rotating shafts 5, each rotating shaft 5 concentrically mounted with multiple driven wheels 2, the driven wheels 2 being sequentially connected and connected to the circumferential rotation output end of the drive module. The control output is connected to the transmission; the circumferential rotation output of the drive module synchronously drives multiple driven wheels to rotate, and the multiple driven wheels to synchronously drive multiple gears to rotate. The multiple gears to synchronously mesh with multiple gears to drive multiple driving rollers to rotate, thus achieving synchronous rotation drive of multiple driving rollers; the angle control output of the drive module synchronously drives multiple driven wheels to rotate at a certain angle, and the multiple driven wheels to synchronously drive multiple gears to rotate. The multiple gears to synchronously mesh with multiple gears to drive multiple output guide rollers and angle plates to rotate at a certain angle, thus achieving synchronous angle drive of multiple output guide rollers and multiple angle plates; modular transmission connection is achieved, which is convenient for expansion and setting, and the driving effect is stable.

[0008] Preferably, the multiple driven wheels 1 and multiple driven wheels 2 are synchronous wheels. The drive module includes a base plate 2 detachably mounted on the main platform. A motor and a servo motor 1 are mounted on the base plate 2. The output shaft of the motor is concentrically mounted with a driving synchronous wheel 1. The driving synchronous wheel 1 and the driven wheels 1, as well as the multiple driven wheels 1, are respectively connected by multiple synchronous belts 1. The output shaft of the servo motor 1 is concentrically mounted with a driving synchronous wheel 2. The driving synchronous wheel 2 and the driven wheels 2, as well as the multiple driven wheels 2, are respectively connected by multiple synchronous belts 2. The base plate 2 is bolted to the main platform. The driving synchronous wheel 1 rotates with the first driven wheel 1 via a synchronous belt 1, and the multiple driven wheels 1 rotate sequentially. The drive module is synchronously connected via multiple synchronous belts. A motor drives a primary synchronous pulley to rotate, which in turn drives a first driven pulley to rotate via a synchronous belt. Multiple driven pulleys are then driven to rotate synchronously via the remaining synchronous belts. A second primary synchronous pulley rotates with a first driven pulley via a synchronous belt. Multiple driven pulleys are then synchronously connected via multiple synchronous belts. A servo motor drives a second primary synchronous pulley to rotate, which in turn drives a first driven pulley to rotate via a synchronous belt. Multiple driven pulleys are then driven to rotate synchronously via the remaining synchronous belts. This modular design of the drive module ensures stable and reliable drive performance and facilitates expansion and deployment.

[0009] Preferably, it further includes multiple tensioning pulleys 1 elastically mounted on multiple base plates 1 and 2, the multiple tensioning pulleys 1 tensioning multiple synchronous belts 1 respectively; multiple tensioning pulleys 2 elastically mounted on multiple base plates 1 and 2, the multiple tensioning pulleys 2 tensioning multiple synchronous belts 2 respectively; through the tensioning action of the multiple tensioning pulleys 1 and multiple tensioning pulleys 2, stable transmission is achieved between the multiple driven pulleys 1 and the driving synchronous pulleys 1, and between the multiple synchronous belts 2 and the driving synchronous pulleys 2.

[0010] Preferably, the device further includes multiple push cylinders II, each mounted on multiple base plates I. Multiple scrapers are mounted on the piston rods of the multiple push cylinders II. These scrapers are located between the angle plates and the drive rollers on the multiple base plates I. The scrapers are used to lift the edges of the self-adhesive label and detach it from the self-adhesive label film. When the self-adhesive label film is fully conveyed and the angle plates cut into the inside of the self-adhesive label film, forming an acute angle, the piston rods of the multiple push cylinders II drive the multiple scrapers upwards. The tips of the scrapers then scrape into the acute angles, lifting the edges of the self-adhesive label and detaching it from the film. The multiple push cylinders II then reset, causing the scrapers to retract and descend, without interfering with the labeling action, thus improving the peeling effect of the self-adhesive label.

[0011] Preferably, it also includes a second servo motor mounted on the main platform. The output shaft of the second servo motor is fixedly connected to one end of the swing arm, and a movable guide roller is rotatably mounted on the other end of the swing arm. The movable guide roller provides rolling guidance for the self-adhesive label film tape that is wound into the second roll frame. The second servo motor drives the swing arm to swing. A torque sensor is set on the output shaft of the second servo motor or the swing arm. The swing arm drives the movable guide roller to actively tension the self-adhesive label film tape that is wound into the second roll frame. The active tensioning effect is detected in real time based on the detection data of the torque sensor. Thus, the second servo motor actively adjusts the output torque to keep the tension stable. This ensures that the self-adhesive label film tape quickly returns to tension when the relative positions of multiple output guide rollers and multiple corner plates switch, thereby improving work stability.

[0012] Preferably, the conveyor belt mechanism includes conveyor belt assembly one and conveyor belt assembly two. Conveyor belt assembly one is located at the front of the main platform, and conveyor belt assembly two is arranged opposite to the main platform. The output end of conveyor belt assembly one is connected to the input end of the side baffle. Side baffles are installed on both sides of conveyor belt assembly one and conveyor belt assembly two. The positioning roller mechanism and the push cylinder are both installed on the frame of conveyor belt assembly two. Conveyor belt assembly one conveys the upright round bottles at a uniform speed. Conveyor belt assembly two conveys multiple round bottles, the same number as multiple labeling modules, to the positioning roller mechanism and pauses. After multiple round bottles are labeled, conveyor belt assembly two starts again to convey multiple round bottles backward, which is practical.

[0013] Preferably, it also includes a driven shaft horizontally rotatably mounted on the frame of the second conveyor belt assembly. The driven shaft is connected to the drive shaft of the second conveyor belt assembly. A bevel gear is concentrically mounted at the end of the driven shaft. A vertical shaft is vertically rotatably mounted on the frame of the second conveyor belt assembly. A bevel gear is concentrically mounted at the lower end of the vertical shaft, and the bevel gear meshes with the first bevel gear. A dial is concentrically mounted at the upper end of the vertical shaft. The dial is located above the joint between the first and second conveyor belt assemblies. Multiple slots are evenly arranged around the edge of the dial. When the drive shaft of the second conveyor belt assembly rotates, it drives the driven shaft and the first bevel gear to rotate. The first bevel gear meshes with the second bevel gear to drive the drive shaft. The vertical shaft and the dial rotate to achieve linkage between the conveyor belt assembly two and the dial. When the dial rotates, it moves the round bottles conveyed on the conveyor belt assembly one by one onto the conveyor belt assembly two through the slots. By optimizing the transmission ratio between the bevel gear one and the dial and the spacing between multiple slots, the round bottles moved onto the conveyor belt assembly two are evenly distributed and the spacing matches the spacing of multiple labeling modules. When the round bottles are being labeled, the conveyor belt assembly two and the dial stop. The dial blocks the round bottles conveyed on the conveyor belt assembly one to prevent the round bottles from interfering with the labeling work, thus saving a round bottle fixed number release mechanism and making it highly practical.

[0014] Preferably, it also includes multiple photoelectric switches installed on the positioning roller mechanism, with each photoelectric switch facing a multiple positioning vertical roller group of the positioning roller mechanism; the multiple photoelectric switches are used to detect whether there is a round bottle between the multiple positioning vertical roller groups of the positioning roller mechanism; when all the multiple photoelectric switches detect a round bottle, the conveyor belt assembly two pauses and starts labeling work, thereby improving the degree of automation.

[0015] Compared with the prior art, the beneficial effects of the present invention are as follows: by setting multiple labeling modules, the modular expansion of different numbers of labeling stations is realized, and multiple labeling stations can be simultaneously and automatically labeled on multiple round bottles at one time, which is more applicable. Compared with the traditional single-station labeling, the average labeling time of round bottles is greatly reduced, thereby improving work efficiency. Attached Figure Description

Detailed Implementation

[0018] To facilitate understanding of the present invention, a more complete description will be given below with reference to the accompanying drawings. The present invention can be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete. Example 1

[0019] like Figures 1 to 9As shown, the self-adhesive round bottle labeling machine includes a reel frame 2 and a reel frame 3 mounted on the main platform 1. The reel frame 2 is used to load the reel of self-adhesive labeling film, and the reel frame 3 is used to wind up the labeling film. It also includes a conveyor belt mechanism 4 mounted on the side of the main platform 1 for conveying round bottles. A movable mounting and positioning roller mechanism 5 is mounted on the side of the frame of the conveyor belt mechanism 4. The positioning roller mechanism 5 is arranged opposite to the main platform 1 and has multiple positioning vertical roller groups for rolling and positioning the round bottles. The fixed end of a push cylinder 6 is mounted on the frame of the conveyor belt mechanism 4, and the piston rod of the push cylinder 6 is connected to the positioning roller mechanism 5 via a transmission connection. A drive module 7 is mounted on the main platform 1. Block 7 is equipped with a circumferential rotation output end and an angle control output end; multiple labeling modules 8 are installed on the main platform 1, the number of multiple labeling modules 8 is the same as the number of positioning vertical roller groups, the multiple labeling modules 8 are respectively arranged opposite to the multiple positioning vertical roller groups, the rolling bottle component of the multiple labeling modules 8 is connected to the circumferential rotation output end of the drive module 7, the state switching component of the multiple labeling modules 8 is connected to the angle control output end of the drive module 7, the self-adhesive labeling film tape output from the first roll frame 2 passes through the state switching component of the multiple labeling modules 8 in sequence and is then wound onto the second roll frame 3, the state switching component of the multiple labeling modules 8 can switch the self-adhesive labeling film tape conveying state and labeling state.

[0020] The main platform 1 is also equipped with necessary guide roller assemblies and tensioning assemblies for the self-adhesive labeling film, as well as drive mechanisms for the first and second roll frames 2 and 3, to ensure rhythmic, stable, and reliable conveying of the self-adhesive labeling film. This is existing technology and will not be described in detail here. A suitable number of labeling modules 8 and an equal number of positioning roller groups are set according to actual work needs. The labeling modules 8 are modularly designed and can be easily installed on the main platform 1, realizing multiple labeling stations evenly arranged along the main platform 1. The spacing of the self-adhesive labels on the self-adhesive labeling film is optimized, and this spacing is related to the spacing between the multiple labeling modules 8. The distance is matched so that multiple self-adhesive labels can be matched with the positions of multiple labeling operations. During operation, a new roll is loaded onto the roll holder 2. After the self-adhesive label film is pulled out, it passes through the guide roller assembly and tensioning assembly in sequence, and then passes through the state switching components of multiple labeling modules 8 in sequence. The state switching components of multiple labeling modules 8 switch to the labeling state. The conveyor belt mechanism 4 runs to transport multiple upright round bottles backward, and the same number of round bottles as the labeling modules 8 are transported quantitatively. When multiple round bottles reach the positioning roller mechanism 5, the push cylinder 6 is activated to push the positioning roller mechanism 5 towards the main platform 1, so that the positioning roller mechanism 5... Multiple positioning vertical roller groups respectively roll and press multiple round bottles onto the rolling round bottle components of multiple labeling modules 8. The drive module 7 drives the rolling round bottle components of multiple labeling modules 8 to rotate synchronously, causing the multiple round bottles to rotate. At the same time, the roller frame 1 2 and roller frame 2 3 cooperate to convey the self-adhesive label film, so that multiple self-adhesive labels are synchronously affixed to the outer wall of multiple round bottles. The push cylinder 6 resets, causing the positioning roller mechanism 5 to retract and release multiple round bottles. The conveyor belt mechanism 4 continues to convey multiple round bottles backward, while simultaneously conveying the next batch of multiple round bottles to the positioning roller mechanism 5. During this process, the state switching unit of multiple labeling modules 8... The device switches to the self-adhesive labeling film conveyor mode. The roller frame 1 2 and roller frame 2 3 work together to quickly convey the length of multiple labels of the self-adhesive labeling film, so that multiple labeling modules 8 correspond to a new label in sequence. The state switching components of multiple labeling modules 8 switch to the labeling state, preparing for the next labeling. Compared with the existing technology, by setting multiple labeling modules 8, the modular expansion of different numbers of labeling stations can be achieved, realizing the simultaneous automatic labeling of multiple round bottles at multiple labeling stations. It has higher applicability and greatly reduces the average labeling time of round bottles compared with traditional single-station labeling, thereby improving work efficiency.

[0021] The labeling module 8 includes a base plate 9 detachably mounted on the main platform 1. A drive roller 10 is rotatably mounted on the base plate 9 via a vertical shaft 1, and the drive roller 10 is used to roll the round bottle. An input guide roller 11 is rotatably mounted on the base plate 9 via a vertical shaft 2. The input guide roller 11 is located behind the drive roller 10 and is used to guide the input portion of the self-adhesive labeling film. An output guide roller 12 is rotatably mounted on the base plate 9 via a vertical shaft 3. The output guide roller 12 is located to the side of the drive roller 10 and is used to guide the self-adhesive labeling film. 12 is used for the output section of the self-adhesive labeling film tape. The angle plate 13 is mounted on the rotating part of the output guide roller 12 by a bracket. The angle plate 13 is located on the side of the output guide roller 12 and is used for peeling and applying the self-adhesive labeling film tape. It also includes a servo motor 31 mounted on the main platform 1. The output shaft of the servo motor 31 is fixedly connected to one end of the swing arm 32. The other end of the swing arm 32 is rotatably mounted with a moving guide roller 33. The moving guide roller 33 rolls and guides the self-adhesive labeling film tape that is wound into the reel frame 3.

[0022] Multiple base plates 9 are evenly installed on the main platform 1 by bolts. The drive roller 10 is a component for rolling the round bottle, and the output guide roller 12 and the angle plate 13 are state switching components. When conveying the self-adhesive label film, the rotating shaft 3 rotates at a certain angle, causing the angle plate 13 to rotate to the side of the output guide roller 12 facing the main platform 1. The end of the self-adhesive label film output from the reel frame 2 is guided by the input guide roller 11 to the side of the main platform 1 and enters the labeling module 8. After being guided by the output guide roller 12 to the side of the conveyor belt mechanism 4, it is output from the labeling module 8, so that the end of the self-adhesive label film enters the next labeling module 8 or is wound onto the reel frame 3. At this time, the reel frame 2 and the reel frame 3 cooperate to convey the self-adhesive label film, so that multiple self-adhesive labels reach multiple base plates 1. Between the input guide roller 11 and the output guide roller 12 on roller 9, the rotating shaft reverses and resets, causing the angle plate 13 to cut into the inside of the conveying self-adhesive label film on the output guide roller 12. The edge of the angle plate 13 presses the self-adhesive label film at an acute angle against the side wall of the drive roller 10. The acute angle causes the edge of the self-adhesive label to detach from the self-adhesive label film. At this time, the round bottle is rolled on the drive roller 10, causing the edge of the self-adhesive label to stick to the outer wall of the round bottle. The drive roller 10 drives the round bottle to roll, and at the same time, it cooperates with the conveying of the self-adhesive label film, so that the self-adhesive label detaches from the film and is automatically attached to the round bottle. The above actions are repeated for continuous automatic labeling. The specific working principle and working effect of the angle plate 13 and the acute angle of the self-adhesive label film are existing technologies and will not be described in detail here.

[0023] Servo motor 2 31 drives swing arm 32 to swing. A torque sensor is set on the output shaft of servo motor 2 31 or on swing arm 32. Swing arm 32 drives guide roller 33 to actively tension the self-adhesive label film tape that is wound into roll frame 2 3. The active tensioning effect is detected in real time based on the detection data of torque sensor. Thus, servo motor 2 31 actively adjusts the output torque to keep the tension stable. This ensures that the self-adhesive label film tape quickly returns to tension when the relative positions of multiple output guide rollers 12 and multiple angle plates 13 are switched, thereby improving working stability. Example 2

[0024] like Figures 1 to 10 As shown, based on the embodiment, it also includes multiple gears 14 concentrically mounted on multiple rotating shafts, each gear 14 meshing with multiple gears 15. The gears 15 are rotatably mounted on multiple base plates 9 via multiple rotating shafts 4. Multiple driven wheels 16 are concentrically mounted on the multiple rotating shafts 4, and the driven wheels 16 are sequentially connected and connected to the circumferential rotation output end of the drive module 7. Multiple gears 17 concentrically mounted on multiple rotating shafts 3, each gear 17 meshing with multiple gears 18. The gears 18 are rotatably mounted on the multiple base plates 9 via multiple rotating shafts 5, and multiple driven wheels 19 are concentrically mounted on the multiple rotating shafts 5, and the driven wheels 19 are sequentially connected and connected to the angle control output end of the drive module 7. The multiple driven wheels 16 and the multiple driven wheels 19 are... The synchronous pulley drive module 7 includes a base plate 20 detachably mounted on the main platform 1. A motor 21 and a servo motor 24 are mounted on the base plate 20. The output of the motor 21 is concentrically mounted with an active synchronous pulley 22. The active synchronous pulley 22 is connected to the driven pulley 16, and the driven pulleys 16 are connected to each other via multiple synchronous belts 23. The output shaft of the servo motor 24 is concentrically mounted with an active synchronous pulley 25. The active synchronous pulley 25 is connected to the driven pulley 19, and the driven pulleys 19 are connected to each other via multiple synchronous belts 26. The module also includes multiple tensioning pulleys 27 elastically mounted on multiple base plates 9 and base plate 20, which tension the multiple synchronous belts 23. Multiple tensioning pulleys 28 elastically mounted on multiple base plates 9 and base plate 20, which tension the multiple synchronous belts 26.

[0025] The base plate 20 is bolted to the main platform 1. Through the tensioning action of multiple tensioning rollers 27 and 28, stable transmission is achieved between the driven rollers 16 and the driving synchronous roller 22, and between the multiple synchronous belts 26 and the driving synchronous roller 25. The driving synchronous roller 22 rotates with the first driven roller 16 via a synchronous belt 23. The driven rollers 16 are sequentially connected synchronously via multiple synchronous belts 23. The motor 21 drives the driving synchronous roller 22 to rotate, which in turn drives the first driven roller 16 via a synchronous belt 23. The remaining synchronous belts 23 drive the driven rollers 16 to rotate synchronously. The driven rollers 16 synchronously drive multiple gears 25 to rotate, and the gears 25 synchronously mesh with multiple gears 14 to drive multiple driving rollers 10. The rotation enables synchronous rotation drive of multiple active rollers 10; the active synchronous wheel 25 rotates with the first driven wheel 19 via a synchronous belt 26, and the multiple driven wheels 19 are synchronously connected via multiple synchronous belts 26 in sequence. The servo motor 24 drives the active synchronous wheel 25 to rotate, and the active synchronous wheel 25 drives the first driven wheel 19 to rotate via a synchronous belt 26. The multiple driven wheels 19 are driven to rotate synchronously via the remaining synchronous belts 26. The multiple driven wheels 19 synchronously drive multiple gears 4 18 to rotate, and the multiple gears 4 18 synchronously mesh with multiple gears 3 17 to drive multiple output guide rollers 12 and angle plates 13 to rotate at a certain angle, thereby achieving synchronous angle drive of multiple output guide rollers 12 and multiple angle plates 13; modular transmission connection is achieved, which is convenient for expansion and setting, and the driving effect is stable.

[0026] It also includes multiple push cylinders 29 installed on multiple base plates 9 respectively. Multiple scrapers 30 are installed on the piston rod top of the multiple push cylinders 29 respectively. The multiple scrapers 30 are located between the corner plate 13 and the drive roller 10 on the multiple base plates 9 respectively. The multiple scrapers 30 are used to scrape up the edge of the self-adhesive label and separate it from the self-adhesive label film.

[0027] Once the self-adhesive label film tape is conveyed and multiple angle plates 13 cut into the inside of the self-adhesive label film tape, forming an acute angle, the piston rods of multiple push cylinders 29 drive multiple scrapers 30 to extend upwards. This causes the tips of the multiple scrapers 30 to scrape into the acute angles, lifting the edges of the self-adhesive label and separating it from the film tape. The multiple push cylinders 29 then reset, causing the multiple scrapers 30 to retract and descend without interfering with the labeling action, thus improving the peeling effect of the self-adhesive label. Example 3

[0028] like Figure 1 , Figure 2 , Figure 11 and Figure 12As shown, based on the embodiment, the conveyor belt mechanism 4 includes a first conveyor belt assembly 34 and a second conveyor belt assembly 36. The first conveyor belt assembly 34 is located on the front side of the main platform 1, and the second conveyor belt assembly 36 is arranged opposite to the main platform 1. The output end of the first conveyor belt assembly 34 is connected to the input end of the side baffle 35. Side baffles 35 are installed on both sides of the first conveyor belt assembly 34 and the second conveyor belt assembly 36. The positioning roller mechanism 5 and the push cylinder 6 are both installed on the frame of the second conveyor belt assembly 36. It also includes a driven shaft 37 that is horizontally rotatably installed on the frame of the second conveyor belt assembly 36. The driven shaft 37 is connected to the second conveyor belt assembly 36. The drive shaft is connected to the drive shaft 37. A bevel gear 38 is concentrically mounted at the end of the driven shaft 37. A vertical shaft 39 is vertically rotatably mounted on the frame of the second conveyor belt assembly 36. A bevel gear 40 is concentrically mounted at the lower end of the vertical shaft 39. The second bevel gear 40 meshes with the first bevel gear 38. A dial 41 is concentrically mounted at the upper end of the vertical shaft 39. The dial 41 is located above the joint between the first conveyor belt assembly 34 and the second conveyor belt assembly 36. Multiple slots are evenly arranged around the edge of the dial 41. The drive shaft 39 also includes multiple photoelectric switches 42 mounted on the positioning roller mechanism 5. The multiple photoelectric switches 42 are respectively opposite to the multiple positioning vertical roller groups of the positioning roller mechanism 5.

[0029] Conveyor belt assembly 34 uniformly conveys upright round bottles. When the drive shaft of conveyor belt assembly 36 rotates, it drives the driven shaft 37 and bevel gear 38 to rotate. Bevel gear 38 meshes with bevel gear 40, driving the vertical shaft 39 and the dial plate 41 to rotate, realizing the linkage between conveyor belt assembly 36 and dial plate 41. When dial plate 41 rotates, it moves the round bottles conveyed on conveyor belt assembly 34 one by one onto conveyor belt assembly 36 through the slots. Furthermore, by optimizing the transmission ratio between bevel gear 38 and dial plate 41 and the spacing between multiple slots, the bottles moved onto conveyor belt assembly 36 are more efficiently moved. The round bottles are evenly distributed and the spacing matches the spacing of the multiple labeling modules 8. Multiple photoelectric switches 42 are used to detect whether there are round bottles between the multiple positioning vertical roller groups of the positioning roller mechanism 5. When multiple photoelectric switches 42 detect round bottles, the second conveyor belt assembly 36 pauses and the dial 41 stops. The dial 41 blocks the round bottles conveyed on the first conveyor belt assembly 34 to prevent the round bottles from interfering with the labeling work, thus saving a round bottle fixed number release mechanism. The labeling work begins. After the multiple round bottles are labeled, the second conveyor belt assembly 36 starts to convey multiple round bottles backward again, improving the degree of automation.

[0030] like Figures 1 to 12As shown, the self-adhesive round bottle labeling machine of the present invention, in operation, firstly requires setting an appropriate number of labeling modules 8 and the same number of positioning roller groups to realize multiple labeling stations evenly arranged along the main platform 1. A new roll is loaded onto the roll holder 2, and the rotating shaft 3 rotates at a certain angle, causing the angle plate 13 to rotate to the side of the output guide roller 12 facing the main platform 1. The end of the self-adhesive labeling film tape output from the roll holder 2 is guided by the input guide roller 11 to the side facing the main platform 1 and enters the labeling module 8. After being guided by the output guide roller 12 towards one side of the conveyor belt mechanism 4, the labeling module 8 is output, so that the end of the self-adhesive label film tape enters the next labeling module 8 or is guided by the moving guide roller 33 and then wound onto the reel frame 2 3. Then the reel frame 1 2 and the reel frame 2 3 cooperate to convey the self-adhesive label film tape, so that multiple self-adhesive labels reach between the input guide roller 11 and the output guide roller 12 on multiple base plates 1 9 respectively. At this time, the rotating shaft 3 reverses and resets, so that the angle plate 13 cuts into the output guide roller 12 when the labeling module 8 is in operation. The self-adhesive label film is fed to the inside, and the edge of the angle plate 13 presses the self-adhesive label film at an acute angle against the side wall of the drive roller 10. Then, the piston rods of multiple push cylinders 29 drive multiple scrapers 30 to extend upwards, so that the tips of the multiple scrapers 30 scrape into the multiple acute angles, lifting the edges of the self-adhesive label and separating it from the film. The multiple push cylinders 29 reset, causing the multiple scrapers 30 to retract and descend. The push cylinder 6 moves to push the positioning roller mechanism 5 toward the main platform 1, so that the multiple positioning vertical roller groups of the positioning roller mechanism 5 respectively place multiple round bottles The labels are rolled and pressed onto multiple active rollers 10, causing the edges of the self-adhesive labels to adhere to the outer wall of the round bottle. The active rollers 10 drive the round bottle to roll, and at the same time, the self-adhesive label film belt is conveyed, so that multiple self-adhesive labels are simultaneously applied to the outer wall of multiple round bottles. Finally, the push cylinder 6 resets, causing the positioning roller mechanism 5 to retract and release multiple round bottles. The conveyor belt assembly 2 36 continues to convey multiple round bottles backward. At the same time, the dial 41 and the conveyor belt assembly 2 36 convey the next batch of multiple round bottles to the positioning roller mechanism 5. The above actions are repeated to achieve continuous labeling.

[0031] The main functions achieved by this invention are: 1. By setting up multiple labeling modules 8, the modular expansion of different labeling stations is realized, enabling multiple labeling stations to automatically label multiple round bottles at one time, which is more applicable. Compared with the traditional single-station labeling, it greatly reduces the labeling time of a single round bottle, thereby improving work efficiency. 2. The labeling module 8 has two modes: self-adhesive label film conveying and labeling. The two modes are automatically switched to realize multi-station conveying of self-adhesive labels. 3. By setting multiple push cylinders 29 and multiple scrapers 30, the edges of the self-adhesive label are scraped up and separated from the film tape, thereby improving the peeling effect of the self-adhesive label; 4. By setting up the linked conveyor belt assembly 36 and dial 41, the round bottles are evenly distributed and matched with the positions of multiple labeling modules 8. When the round bottles are being labeled, the conveyor belt assembly 36 and dial 41 stop, and the dial 41 blocks the round bottles conveyed on the conveyor belt assembly 34 to prevent the round bottles from interfering with the labeling work, thereby saving a round bottle fixed number release mechanism.

[0032] The self-adhesive round bottle labeling machine of the present invention uses common mechanical methods for installation, connection, or setup, and can be implemented as long as it achieves the beneficial effects.
