Description

Technical Field

[0001] This invention relates to the field of bottle-splitting technology, specifically to a rapid bottle-splitting variable-pitch conveying and diverting device. Background Technology

[0002] In bottled product processing production lines, the bottle-dividing variable-pitch conveyor diversion device is a core supporting equipment. It is widely used in the connection between the filling, labeling, testing, and packaging processes of bottled products such as beverages, daily chemicals, and pharmaceuticals. It is mainly used to adjust the spacing and divert the densely conveyed bottled workpieces, so that the bottled workpieces are stably conveyed in a spacing and arrangement that is compatible with the subsequent processing equipment, thus ensuring the continuous operation of the production line.

[0003] The existing conveying and diversion device results in a small gap between bottles during the conveying process due to the uniform rotation speed of the conveying rollers after the bottles enter the container. This leads to the bottles being too densely packed, resulting in less space for secondary processing between each bottle after subsequent diversion and conveying. Summary of the Invention

[0004] The purpose of this invention is to provide a rapid bottle-splitting variable-pitch conveying and diverting device to solve the problems mentioned in the background art.

[0005] To solve the above-mentioned technical problems, the present invention provides the following technical solution: including a device support, one end of which is provided with a first transmission component and the other end of which is provided with a second transmission component. A diversion component is provided on the inner wall of the device support between the first and second transmission components. By arranging the feed variable-pitch conveying, discharge conveying and intermediate diversion structure in sections on the device support, an integrated conveying process of variable-pitch feeding, diversion arrangement and stable discharge of bottled workpieces is realized, and the bottle spacing adjustment and diversion conveying operation are completed. The first transmission component includes multiple first rotating shafts that are evenly distributed. A pitch-changing component is provided at one end of every two connected first rotating shafts. A first transmission roller is fixedly installed on the outer wall of each first rotating shaft. A first buffer pad is fixedly installed on the outer wall of each first transmission roller. The multiple sets of first rotating shafts and first transmission rollers constitute the main body of the feeding and conveying device. The speed difference is formed by the pitch-changing component between adjacent rotating shafts. The first buffer pad is used to achieve flexible conveying. The bottle spacing is adjusted during the conveying process, and the wear of the bottle is reduced during the conveying process. The pitch-changing assembly includes a drive wheel assembly, a driven wheel, and a transmission belt that meshes with the drive wheel assembly and the driven wheel respectively. The outer diameter of the drive wheel assembly is larger than the diameter of the driven wheel. By engaging the drive wheel assembly and the driven wheel with the transmission belt, a stable transmission speed ratio is formed, which causes a speed difference between adjacent first rotating shafts. This enables the automatic widening of the distance between the bottles during the conveying process, thus completing the pitch-changing operation. The variable pitch assembly also includes a telescopic component that is cantilevered and mounted on the bottom of the device bracket. The top of the piston rod of the telescopic component is rotatably mounted with a tension wheel via an ear plate. The tension wheel is connected to the inner wall of one side of the transmission belt. The telescopic component arranged at the bottom drives the tension wheel to move up and down, which can adjust the tension of the transmission belt in real time, adapt to the transmission conditions after the outer diameter of the drive wheel is adjusted, and keep the transmission belt in a close and taut state. A first motor is fixedly installed on one side of the device bracket. One of the first rotating shafts near the input end of the device is connected to the output shaft of the first motor through a coupling. The first motor provides active power to the entire first transmission assembly, drives the first rotating shaft at the input end to rotate, and drives all rotating shafts to move synchronously through the pitch-changing assembly, ensuring continuous operation of feeding, conveying and pitch-changing operations.

[0006] Furthermore, the drive wheel assembly includes a support block, on which multiple drive nuts are evenly distributed at angles on the outer peripheral wall. A driven bevel gear is fixedly installed on the end face of each drive nut inside the support block. A driven screw is threadedly connected to the inner wall of each drive nut. A U-shaped limiting block is fixedly installed at the end of the driven screw extending inside the drive nut. An elastic connecting plate is movably connected between every two connected limiting blocks. The multiple limiting blocks and connecting plates form a perfect circle structure. The drive nuts are driven to rotate by the bevel gear, which drives the driven screw to extend and retract, adjusting the radial position of each limiting block and realizing the adjustment of the overall outer diameter of the drive wheel assembly.

[0007] Furthermore, drive components are provided on both sides of the device support. Each drive component includes multiple equally spaced drive shafts. A third synchronization component is installed on each of the multiple drive shafts on one side. A synchronization shaft is fixedly inserted through the output end of each third synchronization component. The synchronization shaft is rotatably mounted on the bottom of the device support through bearings. A fourth synchronization component is provided at both ends of the synchronization shaft. The output end of the fourth synchronization component is respectively connected to the two sets of drive shafts. A third motor is fixedly installed on the other side of the device bracket. One of the drive shafts is connected to the output shaft of the third motor through a coupling. The third motor provides overall adjustment power and works with the third synchronization component, the synchronization shaft and the fourth synchronization component to realize the synchronous linkage transmission of all drive shafts on both sides of the device. This provides synchronous power input for the subsequent adjustment of the outer diameter of the drive wheel assembly and ensures the consistency of adjustment of each set of pitch components. Adjustment components are also provided on both sides of the device support. The adjustment components include a telescopic plate. Multiple electric push rods are equidistantly arranged on one side of the telescopic plate. The sleeves of the electric push rods are fixedly installed on the inner wall of the device support, and the multiple electric push rods are controlled by the same driver. Multiple movable shafts are equidistantly arranged through bearings on the inner wall of the telescopic plate. Each movable shaft has a driving bevel gear fixedly installed at its end. The driving bevel gear and the driven bevel gear cooperate. The electric push rods under unified control drive the overall displacement of the telescopic plate, realizing the precise meshing and disengagement of the driving bevel gear and the driven bevel gear. Under the drive of the drive component, the driving nut is driven to rotate through the bevel gear transmission, completing the automatic adjustment of the outer diameter of the driving wheel assembly.

[0008] Furthermore, the second transmission component includes a plurality of third rotating shafts that are equidistantly distributed. Two second transmission rollers are symmetrically fixedly installed on the outer wall of each third rotating shaft. A second buffer pad is fixedly installed on the outer wall of each second transmission roller. The second buffer pad has the same structure as the first buffer pad. The second transmission rollers arranged symmetrically on both sides can divert and transport the puzzle pieces. Together with the second buffer pads with the same structure, a flexible rear-end conveying structure is formed, which further reduces the wear problem during bottle transport.

[0009] Furthermore, a first synchronization component is provided between each pair of the three third rotating shafts connected to each phase, and a second synchronization component is provided between one of the three rotating shafts near the input end and one of the first rotating shafts near the output end. The first, second, third, and fourth synchronization components each include two synchronization pulleys and a synchronization belt, and the synchronization of the front and rear conveying structures and the two-sided drive structures is achieved through each set of synchronization components.

[0010] Furthermore, the diversion assembly includes two symmetrically distributed second rotating shafts. A guide roller is fixedly installed on the outer wall of each second rotating shaft. A guide thread is provided on the outer wall of each guide roller. The two sets of guide threads are distributed in opposite directions. By utilizing the two sets of guide thread structures with opposite rotation directions, the bottle body can be subjected to thrust in opposite directions, thereby achieving the effect of diversion and conveying.

[0011] Furthermore, both ends of the first rotating shaft near the output end are fixedly equipped with driving gears. The driving gears are incomplete gears, and the two driving gears are distributed in opposite directions. A connecting gear is movably meshed on one side of the driving gear, and a driven gear is movably meshed on the side of the connecting gear away from the driving gear. The driven gear is fixedly installed on the outer wall of the second rotating shaft. Through the intermittent meshing characteristics of the incomplete gears, the two sets of guide rollers can be driven to rotate at different times, thereby pushing the connected bottles to flow in different directions.

[0012] Furthermore, a buffer protrusion is fixedly installed on the outer wall of the first buffer pad, and the buffer protrusion has a hollow structure; The buffer bumps are arranged in multiple groups in a circumferential array on the outer wall of the first buffer pad, and each group of buffer bumps is axially staggered on the outer wall of the first buffer pad. The buffer bumps can buffer the vibration and squeezing force of the conveying process, improve the smoothness of the conveying process, and reduce the damage to the bottle body from impacts.

[0013] Furthermore, two limiting components are symmetrically arranged on the top of the device support. Each limiting component includes a support plate fixed to the top of the device support. A guide rail is fixedly installed on the outer surface of the support plate. A second motor is fixedly installed at one end of the guide rail. The output shaft of the second motor extends into the interior of the guide rail and is fixedly installed with a transmission screw. The threads at both ends of the transmission screw are distributed in opposite directions, and two sliders are symmetrically arranged on the outer wall of the transmission screw. One end of each slider passes through the support plate through a groove and is hinged to a movable rod. One end of each movable rod is hinged to a movable plate. The second motor drives the reverse-threaded transmission screw to rotate, causing the sliders on both sides to move towards or away from each other. The movable rod hinge transmission structure enables the adjustment of the spacing between the movable plates, and the width of the conveying channel can be flexibly adjusted according to the bottle specifications.

[0014] Furthermore, the two ends of the movable plate are arranged in a U-shape, and guide plates are hinged to both ends of the movable plate. The end of the guide plate opposite to the movable plate is hinged to the inner surface of the support plate. The guide plates hinged at both ends can guide the bottle during transmission, ensuring that the bottle slides effectively between the movable plates.

[0015] Compared with the prior art, the beneficial effects of the present invention are: This invention features an adjustable variable-diameter drive wheel assembly, which, together with the drive assembly and adjustment assembly, enables the adjustment of the outer diameter of the drive wheel. This allows for flexible changes in the transmission speed ratio of adjacent conveying shafts, and enables the adjustment of the spacing during bottle conveying according to different bottle sizes and the spacing requirements of different processes. As a result, it can adapt to the production and conveying scenarios of bottled workpieces of various specifications.

[0016] During the conveying process, when the bottle passes through the conveying area between two sets of guide rollers, the reverse threaded guide structure can apply a lateral guiding force to the moving bottle, thereby driving the bottle to shift back and forth to both sides, achieving the function of rapid diversion.

[0017] This invention uses a second motor to drive a transmission screw with reversed threads at both ends to rotate, which in turn drives symmetrically distributed sliders to move in opposite directions or in a straight line along the guide rail. In conjunction with the hinged transmission structure between the movable rod and the guide plate, the two movable plates on both sides can be driven to complete the spacing adjustment operation. This allows for flexible adjustment of the width of the conveying channel between the two sets of movable plates, thereby facilitating the limiting operation when conveying the bottle.

[0020] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0021] likeFigure 1 - Figure 9 As shown, this embodiment discloses a rapid bottle-splitting variable-pitch conveying and diversion device, including the device as a whole. The device support 1 adopts a frame-type integrated structure, which has stable overall load-bearing performance and can meet the requirements of long-term continuous conveying operations. The device support 1 is equipped with a first transmission component and a second transmission component at both ends along the workpiece conveying direction. The first transmission component is responsible for feeding and conveying and adjusting the bottle pitch. The second transmission component is used for stable discharge conveying of the bottle after pitch diversion. The inner wall of the device support 1 is equipped with a diversion component in the middle transition area between the first transmission component and the second transmission component, which is used to guide the bottle after pitch diversion to the side, so as to realize the orderly diversion of a single row of bottles.

[0022] The first transmission component is the core structure of the device for feeding and pitch changing. It includes multiple sets of first rotating shafts 2 that are equidistantly distributed along the conveying direction. All first rotating shafts 2 are mounted parallel to each other on the inner side of the device support 1. Both ends are rotatably connected to the device support 1 through bearing structures to ensure smooth and stable rotation of the shafts. A set of pitch changing components is installed at the end of each pair of adjacent first rotating shafts 2. The pitch changing components realize differential transmission between adjacent first rotating shafts 2, thereby changing the bottle conveying distance. A first transmission roller 6 is fixedly installed on the outer wall of each first rotating shaft 2. The first transmission roller 6 rotates synchronously with the first rotating shaft 2. The friction between the roller and the bottle drives the bottled workpiece forward to achieve continuous feeding and conveying.

[0023] In this embodiment, the outer wall of each first conveying roller 6 is fixedly covered with a first buffer pad 7. The first buffer pad 7 is in direct contact with the bottle body, which can weaken the hard contact force between the bottle body and the roller body during the conveying process, reduce the wear of the bottle body, and adapt to the conveying operation of bottles of various materials.

[0024] The variable pitch assembly is a key structure for achieving adjustable bottle spacing. Specifically, it includes a drive wheel assembly 3, a driven wheel 4, and a transmission belt 5. The drive wheel assembly 3 and the driven wheel 4 are respectively mounted at the ends of two adjacent first rotating shafts 2. The transmission belt 5 is sleeved on the outside of the drive wheel assembly 3 and the driven wheel 4 to achieve linkage transmission between the two.

[0025] To further explain, the outer diameter of the driving wheel assembly 3 is larger than the diameter of the driven wheel 4. The large-diameter driving wheel assembly 3 and the small-diameter driven wheel 4 have the same linear velocity but different angular velocities, resulting in a fixed speed difference between the two connected first rotating shafts 2. Multiple sets of pitch-changing assemblies are arranged sequentially along the conveying direction, causing the speed of each subsequent set of first rotating shafts 2 to change differentially at each level. Under the action of progressive differential conveying, the conveying speed of the densely packed bottles entering the device increases sequentially, causing the originally densely packed bottles to gradually increase in spacing, realizing automated continuous pitch-changing. This creates a uniform and stable working gap between each pair of adjacent bottles, meeting the space requirements of subsequent workstations.

[0026] In this embodiment, the variable pitch assembly also includes a tension adjustment structure. The bottom of the device bracket 1 is fixedly installed with a telescopic member 29 via a cantilever. The telescopic member 29 adopts an automatic telescopic structure. The top of the piston rod of the telescopic member 29 is fixedly fitted with an ear plate. The tension wheel 30 is rotatably installed on the inner side of the ear plate via a bearing. The wheel surface of the tension wheel 30 is in close contact with the inner wall of one side of the transmission belt 5. During the operation of the equipment, the tension wheel 30 can be moved up and down by the telescopic movement of the telescopic member 29, thereby adjusting the tension of the transmission belt 5 to meet the transmission requirements after the outer diameter of the drive wheel assembly 3 is adjusted, and to avoid the problem of the transmission belt 5 becoming loose and slipping.

[0027] The first motor 9 is fixedly installed on one side of the device bracket 1. The first rotating shaft 2 near the input end of the device is connected to the output shaft of the first motor 9 through a coupling. The first motor 9 serves as the main power source of the first transmission component. After starting, it can drive the first rotating shaft 2 at the input end to rotate stably. Then, through the transmission action of each set of pitch-changing components, it drives all subsequent first rotating shafts 2 to operate in sequence, so that the entire first transmission component forms a continuous differential conveying system, ensuring continuous feeding and pitch-changing operations.

[0028] The drive wheel assembly 3 has a variable outer diameter adjustment function, specifically including a support block 301. The support block 301 is fixedly mounted on the end of the first rotating shaft 2 and rotates synchronously with the first rotating shaft 2. Multiple sets of drive nuts 302 are distributed at equal angles along the circumferential direction on the outer peripheral wall of the support block 301. All drive nuts 302 are rotatably mounted on the outer peripheral wall of the support block 301 through bearings. A driven bevel gear 303 is fixedly mounted on the end face of each drive nut 302 inside the support block 301. The driven bevel gear 303 can follow the drive nut 301. 02. The driven screw 304 is connected to the inside of each active nut 302 through a threaded structure. The driven screw 304 can achieve telescopic displacement under the rotation of the active nut 302. The outer end of the driven screw 304 extending out of the active nut 302 is fixedly equipped with a U-shaped limiting block 305. An elastic connecting plate 306 is movably assembled between two adjacent limiting blocks 305. Multiple sets of limiting blocks 305 and elastic connecting plates 306 are spliced ​​together to form a complete circular transmission structure, which constitutes the outer edge transmission surface of the active wheel assembly 3.

[0029] In actual operation, the radial position of the adjustable limit block 305 of the driven screw 304 is adjusted to change the overall rotational outer diameter of the drive wheel assembly 3, thereby realizing the adjustable switching of the transmission speed ratio to adapt to the adjustment requirements of different bottle spacing. The elastic connecting plate 306 can adapt to the displacement spacing of the limit block 305 to always ensure the integrity of the overall wheel structure.

[0030] Drive components are provided on both sides of the device bracket 1 to provide overall power support for the adjustment of the outer diameter of the drive wheel assembly 3. The drive components include multiple sets of equally spaced drive shafts 31. A third synchronization component 33 is mounted on all drive shafts 31 on one side of the device bracket 1. The third synchronization component 33 consists of two synchronous pulleys and a synchronous belt, which can realize the synchronous linkage operation of all drive shafts 31 on a single side. A synchronous shaft 34 is fixedly inserted through the output end of each third synchronization component 33. The synchronous shaft 34 is rotatably mounted at the bottom position of the device bracket 1 through bearings. A fourth synchronization component 35 is mounted on both ends of the synchronous shaft 34. The fourth synchronization component 35 also adopts the transmission structure of synchronous pulleys and synchronous belts. The output end of the fourth synchronization component 35 is respectively driven and connected to the drive shafts 31 on both sides of the device bracket 1 to realize the synchronous operation of the drive structure on both sides of the device.

[0031] In this embodiment, a third motor 32 is fixedly installed on the other side of the device bracket 1. One of the drive shafts 31 is connected to the output shaft of the third motor 32 via a coupling. The third motor 32 serves as the total power source for the drive assembly. When running, it can drive the drive shaft 31 on one side to rotate. Then, through the step-by-step transmission of the third synchronization assembly 33, the synchronization shaft 34 and the fourth synchronization assembly 35, the synchronous operation of all drive shafts 31 is realized, providing a stable power input for the subsequent adjustment assembly.

[0032] Adjustment components are provided on both sides of the device support 1 to match the power of the drive component and complete the outer diameter adjustment of the drive wheel component 3. The adjustment components include a telescopic plate 36. Multiple sets of electric push rods 37 are distributed in an equidistant array on one side of the telescopic plate 36. The sleeve ends of all electric push rods 37 are fixedly installed on the inner wall of the device support 1, and all electric push rods 37 are controlled by the same driver to achieve synchronous telescopic movement.

[0033] In this embodiment, multiple sets of movable shafts 38 are equidistantly arranged inside the telescopic plate 36 through bearings. The movable shafts 38 can rotate freely inside the telescopic plate 36. Each movable shaft 38 is fixedly equipped with a driving bevel gear 39 at its end. The driving bevel gear 39 and the driven bevel gear 303 inside the driving wheel assembly 3 mesh with each other.

[0034] During actual adjustment, the electric push rod 37 synchronously extends and retracts, causing the telescopic plate 36 to shift as a whole, so that the driving bevel gear 39 and the driven bevel gear 303 mesh precisely. After the drive assembly drives the movable shaft 38 and the driving bevel gear 39 to rotate, it can drive the driven bevel gear 303 and the driving nut 302 to rotate, thereby driving the driven lead screw 304 to extend and retract, completing the precise adjustment of the outer diameter of the driving wheel assembly 3 and realizing the flexible switching of the variable pitch ratio.

[0035] It should be noted that the movable shaft 38 has a regular hexagonal shape, and the drive shaft 31 has a regular hexagonal through groove inside that matches the shape of the movable shaft 38, so that the drive shaft 31 and the movable shaft 38 can maintain a rotational transmission connection after the movable shaft 38 slides.

[0036] The second transmission component is used for the stable discharge and conveying of bottles after diversion. It includes multiple sets of equidistantly distributed third rotating shafts 16. The third rotating shafts 16 are mounted in parallel to the discharge end of the device support 1 and are arranged in parallel with the first rotating shaft 2. Two second transmission rollers 19 are symmetrically fixedly installed on the outer wall of each third rotating shaft 16. The outer peripheral wall of each second transmission roller 19 is fixedly covered with a second buffer pad 20. The two sets of second transmission rollers 19 can be used for the conveying of bottles after diversion.

[0037] A first synchronization component 17 is installed between each of the two adjacent third rotating shafts 16. The first synchronization component 17 consists of a synchronous pulley and a synchronous belt, which can ensure that all third rotating shafts 16 rotate synchronously at the same speed. A second synchronization component 18 is installed between the third rotating shaft 16 near the input end and the first rotating shaft 2 near the output end. The second synchronization component 18 also adopts a synchronous pulley and synchronous belt transmission structure, so that the first transmission component and the second transmission component can be driven by one motor at the same time, which is beneficial to saving energy consumption.

[0038] The diversion assembly is equipped with two symmetrically arranged second rotating shafts 10. The second rotating shafts 10 are rotatably connected to the device bracket 1 via bearings. Guide rollers 11 are fixedly mounted on the outer shaft of each second rotating shaft 10. The guide rollers 11 can directly contact and cooperate with the side wall of the bottle being conveyed. The outer circular surface of the guide rollers 11 is integrally machined with guide threads 12. The guide threads 12 on the surfaces of the left and right guide rollers 11 rotate in opposite directions, with one side being a forward thread and the other side being a reverse thread. When the bottle after the pitch change enters the diversion area between the two sets of guide rollers 11, the reverse guide threads 12 in the rotating state will generate a lateral thrust on the bottle, which can continuously guide the single row of conveyed bottles to shift to the left and right sides respectively, so that the single row of dense bottles is gradually separated into double rows for conveying, thus completing the stable diversion operation.

[0039] In this embodiment, the opening of the guide thread 12 is rounded to prevent wear on the bottle body when it is being diverted.

[0040] The first rotating shaft 2, near the output end of the first transmission component, has symmetrically fixed drive gears 13 at both ends. The drive gears 13 adopt an incomplete gear structure, with only part of the tooth structure remaining in the gear body. The tooth arrangement of the left and right drive gears 13 is symmetrically distributed in opposite directions. A connecting gear 14 is meshed on the outer side of each drive gear 13. The connecting gear 14 serves as an intermediate transmission gear, playing the role of power transfer and transmission reversal. A driven gear 15 is meshed on the side of the connecting gear 14 away from the drive gear 13. The driven gear 15 is fixedly sleeved on the outer side of the lower end shaft of the second rotating shaft 10, and rotates synchronously with the second rotating shaft 10.

[0041] In this embodiment, the first rotating shaft 2 rotates continuously and drives the two end drive gears 13 to rotate synchronously. The intermittent meshing transmission characteristics of the incomplete gears cause the connecting gear 14 and the driven gear 15 to rotate intermittently, thereby driving the second rotating shaft 10 and the guide roller 11 to run intermittently, and then driving the bottle to be conveyed to both sides respectively.

[0042] The outer surface of the first buffer pad 7 is integrally formed with several buffer protrusions 8. The buffer protrusions 8 are set as a hollow cavity structure. The hollow structure has good elastic deformation space. During the bottle conveying process, the bottle surface is in direct contact and squeezed with the buffer protrusions 8. The hollow buffer protrusions 8 can generate moderate elastic contraction to offset the squeezing force and vibration generated during the bottle conveying process, and avoid hard squeezing that causes the bottle to deform or break.

[0043] In this embodiment, multiple sets of buffer bumps 8 are evenly arranged in a circumferential array on the outer wall of the first buffer pad 7. The buffer bumps 8 in each circumferential array are evenly distributed along the outer circle of the roller. The buffer bumps 8 in each set are arranged in a staggered manner in the axial direction of the first buffer pad 7. The positions of adjacent buffer bumps 8 are staggered, which can increase the contact area between the buffer bumps 8 and the bottle body and ensure that any position on the outer wall of the bottle can be effectively buffered and protected.

[0044] To further explain, the second buffer pad 20 has the same structure as the first buffer pad 7, and its outer peripheral wall is also provided with buffer protrusions 8, which can buffer the conveying of the bottle after diversion.

[0045] Two sets of limiting components are symmetrically mounted on the top left and right sides of the device bracket 1. The two sets of limiting components work together to limit and guide the left and right sides of the bottle during the bottle conveying process, and can also be adapted to adjust the width of bottles with different diameters.

[0046] Further explanation: The limiting component includes a support plate 21, which is vertically fixedly welded to the top end face of the device bracket 1. The plate surface is set perpendicular to the conveying direction. A guide rail 22 is horizontally fixedly installed on the outer plate surface of the support plate 21. A sliding groove adapted to the movement of the slider 25 is opened inside the guide rail 22 to ensure that the slider 25 moves linearly. A second motor 23 is fixedly installed at one end of the guide rail 22. The second motor 23 is an adjustable speed forward and reverse motor. The output shaft of the second motor 23 extends axially into the guide rail 22, and the end of the output shaft is fixedly connected to the transmission screw 24, driving the transmission screw 24 to rotate synchronously. The left and right ends of the transmission screw 24 are machined with threaded structures with opposite directions of rotation. Two sliders 25 are symmetrically mounted on the rod body of the transmission screw 24. The threaded holes inside the sliders 25 are matched and engaged with the threads of the transmission screw 24.

[0047] In this embodiment, when the second motor 23 rotates forward or reverse, the reverse thread structure can drive the two sliders 25 to slide linearly along the guide rail 22, moving closer or further apart, thereby flexibly adjusting the distance between the sliders 25. The lower end of each slider 25 passes through the preset groove of the support plate 21 and extends outward. The bottom end of the slider 25 is hinged to the movable rod 26. The bottom ends of the movable rods 26 on both sides are hinged to the top of the movable plate 27, forming a symmetrical linkage transmission structure. The linear movement of the slider 25 can be driven by the push and pull of the movable rod 26, which in turn drives the movable plate 27 to complete the position adjustment.

[0048] The movable plate 27 adopts a long strip plate structure, and both the left and right ends of the movable plate 27 are set as U-shaped structures. The U-shaped structure can reserve sufficient hinge installation space, avoid movement interference, and adapt to the assembly requirements of the movable rod 26 and the guide plate 28. The guide plate 28 is hinged to the inner side of both the left and right ends of the movable plate 27. The guide plate 28 is a long strip plate structure. The end of the guide plate 28 away from the movable plate 27 is hinged and fixed to the inner side of the support plate 21, so that the movable plate 27, the guide plate 28, the movable rod 26 and the support plate 21 form a four-bar linkage adjustment structure.

[0049] During the movement of the slider 25 and the movable rod 26, the two ends of the movable plate 27 synchronously drive the guide plate 28 to rotate, so that the movable plate 27 remains tilted. This allows the bottle to be effectively guided between the two sets of movable plates 27 during the bottle conveying process, thereby achieving the limited conveying of bottles with different fins. This prevents the bottles from swaying left and right, deviating or derailing during the conveying and diversion process, and further improves the overall accuracy and stability of the bottle diversion and diversion operation.

[0050] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
