Description

Technical Field

[0001] This invention relates to the field of food filling technology, specifically to a glass bottle feeding device for a fully automatic capping machine. Background Technology

[0002] On the bottling production lines for food, pharmaceuticals, and daily chemical products, glass bottles must undergo strict feeding, sorting, and sterilization processes before filling and capping.

[0003] Existing glass bottle feeding and sterilization devices generally have the following specific problems in actual operation, making it difficult to meet the matching requirements of high-speed, high-cleanliness fully automatic capping machines.

[0004] On a glass bottle filling production line, bottles must undergo feeding, sorting, and internal disinfection before entering a fully automatic capping machine. Existing glass bottle feeding devices used in fully automatic capping machines have the following specific defects in actual operation.

[0005] Firstly, in the steam sterilization process inside the bottle, existing devices typically have the steam nozzles fixedly mounted on the frame. When the bottle is transported to the sterilization station by the rotary mechanism, if the bottle slightly wobbles due to clamping gaps, mechanism vibration, or differences in bottle dimensions, the fixed nozzles cannot compensate accordingly. This causes the steam jet direction to deviate from the central axis of the bottle opening, resulting in some steam failing to effectively inject into the bottle's interior and incomplete sterilization of the inner wall. Similarly, in the ultraviolet sterilization process, the fixedly installed ultraviolet lamps cannot adapt to changes in the bottle opening position, resulting in unstable irradiation distances and sterilization dead zones inside the bottle.

[0006] Secondly, regarding bottle clamping, existing devices mostly employ a single clamping method, either clamping only the bottle body or only the bottle opening. For smooth-surfaced cylindrical glass bottles, clamping only the bottle body can easily cause circumferential slippage or tilting during rotation; clamping only the bottle opening makes it difficult to ensure the bottle body maintains an upright and stable posture before entering the disinfection station. Neither method can ensure the precise relative position between the bottle opening and the disinfection element, affecting the disinfection effect.

[0007] Third, most existing devices use a single-channel bottle feeding system, which limits the feeding efficiency. Some devices that use a dual-channel bottle feeding system lack a confluence mechanism that can alternately guide the flow according to the two incoming materials in real time. As a result, the two bottles frequently interfere and get stuck at the point of parallel flow, causing disorder in the feeding cycle. Summary of the Invention

[0069] The technical solutions of the present invention will be clearly and completely described below with reference to the embodiments of the present invention. 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 of ordinary skill in the art without creative effort are within the scope of protection of the present invention.

[0070] Example

[0071] like Figures 1-15 As shown, a glass bottle feeding device for a fully automatic capping machine mainly includes a feeding mechanism 1, a double-sided input mechanism 2, a bottle unloader 3, a sterilizer 6, two intermittent conveyors 4, and an intermittent feeder 5.

[0072] The feeding mechanism 1 undertakes the initial feeding task of materials. It has two parallel feeding and output ends, which can divide a batch of glass bottles into two paths and supply them outward. The double-sided input mechanism 2 is located directly below the two feeding and output ends of the feeding mechanism 1. It is used to receive the glass bottles falling from the two output ends and merge the two paths of bottles into one path and continue to convey them forward. The inlet of the bottle unscrambler 3 is connected to the conveying end of the double-sided input mechanism 2. The bottle unscrambler 3 uses a rotating component to organize the scattered bottles into a single row with the bottle mouths vertically upward and output them outward one by one. The sterilizer 6 is installed on the bottle outlet side of the bottle unscrambler 3 and is used to sterilize the inside of the bottle. The sterilizer 6 has multiple clamping components 62 inside. The clamping components 62 are evenly arranged on the rotating body of the sterilizer 6 along the circumference. Each clamping component 62 can independently clamp a glass bottle. A steam sterilization component 63 is provided on the side of the clamping component 62, and an ultraviolet sterilization component 64 is provided on the top of the clamping component 62.

[0073] During operation, the clamping component 62 first securely clamps the bottle. Then, the rotating body of the sterilizer 6 revolves, causing the bottle to pass through the steam sterilization station and the ultraviolet sterilization station in sequence. At the steam sterilization station, the steam sterilization component 63 sprays high-temperature steam into the bottle, using heat to denature and coagulate the proteins of the bacteria, thus completing steam sterilization. At the ultraviolet sterilization station, the ultraviolet sterilization component 64 irradiates short-wave ultraviolet light into the bottle, destroying the DNA or RNA molecular structure of the microorganisms, thus completing ultraviolet sterilization.

[0074] Two intermittent conveyors 4 are respectively set on the feed side and discharge side of the sterilizer 6. The intermittent conveyors 4 feed the bottles into and out of the sterilizer 6 in a stepping manner to realize the intermittent conveying of the bottles. The intermittent feeder 5 is installed at the end of the intermittent conveyor 4 on the discharge side and is used to feed the sterilized bottles out one by one at uniform time intervals to supply the fully automatic capping machine.

[0075] The specific structure and transmission principle of each mechanism are explained in detail below:

[0076] The feeding mechanism 1 includes a placement frame 11 and a three-axis mover 15. The placement frame 11 is a gantry-type main frame welded from profiles. Two sets of symmetrically arranged placement guide rails 12 are laid at its bottom. The placement guide rails 12 are linear guide rails. A height limiting rope 13 is horizontally stretched at the inlet end of the placement frame 11 to limit the maximum height of the bottle stack on the feeding trolley 14. The bottom slider of the feeding trolley 14 is fitted onto the placement guide rail 12 and can slide along the rail from the inlet end to the outlet end. The three-axis mover 15 is installed on the top crossbeam of the placement frame 11. It consists of an X-axis linear module, a Y-axis linear module, and a Z-axis lifting module, forming a rectangular coordinate robot. Each linear module is driven by a stepper motor and a ball screw to achieve linear motion. The working principle of the stepper motor is that each time the driver receives a pulse signal, it controls the energization phase sequence of the motor windings to change, causing the rotor to rotate by a fixed step angle. The angular displacement is converted into linear displacement of the slide table through the ball screw. To achieve point-to-point control, the three-axis mover 15 is designed with two independent Z-axis output ends. Each output end is controlled by its own Z-axis stepper motor and lead screw mechanism for lifting and lowering. A three-jaw flexible gripper 16 is installed at its bottom. The three-jaw flexible gripper 16 is a parallel opening and closing type air gripper driven by compressed air. The intake and exhaust directions are controlled by a two-position five-way solenoid directional valve to achieve synchronous centripetal gripping or outward opening of the three claw fingers. A hydraulic top connector 17 is also installed at the end of the guide rail 12. The hydraulic top connector 17 consists of a hydraulic cylinder, a hydraulic pump station and a solenoid directional valve. The motor of the hydraulic pump station drives the oil pump to rotate and pressurize the hydraulic oil for output. The solenoid directional valve switches the oil circuit direction and controls the piston rod of the hydraulic cylinder to lift and lower, thereby lifting the tray and bottle stack on the trolley 14 to the preset gripping height. During gripping, the three-axis mover 15 drives the two three-jaw flexible grippers 16 to alternately move in space, grabbing the bottles from the tray and transferring them to the top of the double-sided input mechanism 2 for release.

[0077] The double-sided input mechanism 2 receives the bottle released by the feeding mechanism 1. The double-sided input mechanism 2 includes a first input track 21, a second input track 22, a converging track 23, and a cylinder switching push plate 24. The inlets of the first input track 21 and the second input track 22 are located directly below the two feeding and output ends of the three-axis mover 15, respectively. The outlets gradually converge and meet at the inlet of the converging track 23. The converging track 23 is a horizontal conveying trough. A belt conveyor driven by an AC geared motor is installed in the trough. The AC geared motor is powered by a single-phase AC power supply. It generates a rotating magnetic field through capacitor phase shifting, drives the rotor to rotate, and drives the belt drive pulley after being reduced by the gearbox. The bottle is pulled forward by friction.

[0078] At the junction of the confluence track 23 and the first input track 21 and the second input track 22, a cylinder switching push plate 24 is installed. The cylinder switching push plate 24 consists of a rack and pinion swing cylinder and a baffle. The working principle of the swing cylinder is that compressed air pushes the piston to make linear motion, and the rack on the piston rod drives the gear on the output shaft to rotate, converting the linear motion into the swing of the output shaft within a certain angle. The electromagnetic reversing valve switches the air intake and exhaust at both ends of the air port, which controls the baffle to swing back and forth. The control system judges the material condition based on the photoelectric sensor signal at the entrance of the two tracks, and controls the electromagnetic valve to make the baffle alternately close the first input track 21 or the second input track 22, so that the two bottles flow into the confluence track 23 in an orderly manner and prevent blockage.

[0079] The merged bottles enter the bottle unscrambler 3, which consists of a circular bottle unscrambler frame 31, an input channel 32, an output channel 33, a fixed shaft 34, a guide plate 35, a servo motor 36, and a rotating circular plate with a central hole 37.

[0080] The circular bottle-sorting frame 31 is a disc-shaped shell. An input channel 32 is located on its circumferential sidewall and connects to the outlet of the converging track 23. An output channel 33 is located on the other side and extends tangentially. A central rotating disc 37 is a stainless steel disc with a large central hole. The bottom of the central rotating disc 37 is rotatably mounted inside the circular bottle-sorting frame 31 via a thrust ball bearing. A servo motor 36 is installed at the bottom of the circular bottle-sorting frame 31. This is an AC servo motor, and its working principle is similar to that of the aforementioned servo motors: the driver receives pulse commands, controls the stator winding current to generate a rotating magnetic field, and the permanent magnets on the rotor rotate synchronously. The tail encoder provides real-time feedback of the angle and speed, forming a closed loop. The ring control enables speed and position control. The output shaft of the servo motor 36 is equipped with a drive sprocket, and the bottom surface of the central rotating plate 37 is equipped with a driven sprocket. The two are connected by a transmission chain 38. The fixed shaft 34 extends upward from the center of the bottom plate of the circular bottle-sorting frame 31, passes through the central hole of the central rotating plate 37, and a stationary guide plate 35 is fixedly installed at its top. The bottle falls into the rotating central rotating plate 37 from the input channel 32. Under the action of centrifugal force and disc friction, it moves with the plate. When it touches the arc surface of the guide plate 35, it is gradually guided to the outer edge of the disc and finally arranged in a single row and squeezed out from the output channel 33, completing the bottle sorting action.

[0081] Bottles exiting the bottle unscrambler 3 enter the intermittent conveyor 4 on the feed side. The intermittent conveyor 4 includes a conveying track 41, multiple multi-groove guide frames 43, and a multi-groove guide frame 46. The conveying track 41 is a long strip base, inside which multiple equidistantly arranged conveying rollers 411 are rotatably installed along the length direction to support the bottom of the bottle. Above the conveying track 41, multiple multi-groove guide frames 43 and a multi-groove guide frame 46 are installed along the conveying direction. The multi-groove guide frames 43 are disc-shaped components, and multiple arc-shaped vents for accommodating the sidewalls of the bottle are evenly distributed on the outer circumference of the multi-groove guide frames 43. The groove has a rotating shaft 432 fixedly connected to its bottom. The rotating shaft 432 is vertically mounted on the side wall of the conveying track 41 via a rolling bearing seat. The multi-groove guide frame 43 is staggered on both sides of the conveying track 41, with adjacent two located on the left and right sides respectively. Each pair of rotating shafts 432 on the same side is connected by a synchronous chain 45, which is a sleeve roller chain. On the two rotating shafts 432 located at the ends of the conveying track 41, each is fixedly fitted with a meshing gear 44 by a key. The two meshing gears 44 have the same number of teeth and mesh with each other, thereby making the multi-groove guide frame on both sides... The guide frame 43 rotates synchronously at angles of equal size but opposite directions, alternately pushing the bottle from one side to the other to achieve intermittent progress. The structure of the multi-groove guide frame 46 is similar to that of the multi-groove guide frame 43, but its outer diameter and the number of grooves are adapted to the interface of the sterilizer 6, and it is installed on the inlet side near the sterilizer 6. A long shaft 462 is fixedly connected to the bottom of the multi-groove guide frame 46. The long shaft 462 is rotatably mounted through a bearing seat. A rotating shaft 432 located at the other end is connected to the long shaft 462 through a conveyor chain 47 to transmit power to the multi-groove guide frame 46. In order to increase friction... To protect the bottle, a first flexible conveying pad 431 is attached to the grooved surface of the multi-groove guide frame 43, and a second flexible conveying pad 461 is attached to the grooved surface of the multi-groove guide frame 46, both made of polyurethane. The lower end of one of the rotating shafts 432 is connected to a stepper motor 42 via a flexible coupling. The stepper motor 42 works as follows: the controller sends a pulse sequence to the driver, which energizes each phase winding of the motor according to the pulse sequence, generating a stepping magnetic field. The rotor rotates at a fixed angle following the magnetic field. The pulse frequency controls the rotational speed, and the pulse quantity controls the angular displacement. When there are no pulses, the motor self-locks under the holding torque. The stepper motor 42 rotates intermittently, driving all the multi-groove guide frames 43 and 46 to rotate synchronously through a fixed indexing angle via a transmission chain consisting of a synchronous chain 45, meshing gears 44, and a conveying chain 47. This allows the bottle to advance one station along the conveying direction, thus feeding the bottle one by one into the clamping assembly 62 of the sterilizer 6.

[0082] The disinfection device 6 includes not only the aforementioned clamping assembly 62, steam disinfection assembly 63, and ultraviolet disinfection assembly 64, but also a power assembly 61. The power assembly 61 consists of a rotary motor 611 and a linear shaft 612. The rotary motor 611 is also a servo motor, its body fixedly mounted on the bottom frame of the disinfection device 6. A drive sprocket is mounted on its output shaft. The linear shaft 612 is rotatably mounted inside the housing of the disinfection device 6 via an angular contact ball bearing, with a driven sprocket mounted at its lower end. The connecting chain 613 is a ring-shaped transmission chain sleeved on the two sprockets. The rotary motor 611 rotates under the controller's command, driving the linear shaft 612 to rotate via the connecting chain 613. A rotating frame 614 is fixedly connected to the top of the linear shaft 612, and the aforementioned clamping assemblies 62 are mounted on this rotating frame 614. The rotating frame 614 drives each clamping assembly 62 and the bottle body to intermittently revolve around the axis of the linear shaft 612, sequentially passing through each disinfection station.

[0083] The clamping assembly 62 specifically includes a flexible clamp 621 and a bottle neck clamp 622. The flexible clamp 621 consists of a limiting frame 6211, two flexible claws 6214, and a hinge shaft 6212. The limiting frame 6211 is fixedly connected to one side of the hinge shaft 6212 and is rotatably mounted in the rotating frame 614 through the hinge shaft 6212, so that the limiting frame 6211 can swing around the axis of the hinge shaft 6212. The two flexible claws 6214 are respectively installed on the top of both sides of the limiting frame 6211, and the claw bodies are made of elastic steel plates. Each of the bottle mouth grippers 622 and 6213 is equipped with a pneumatic converter 6213 at its tail end. The pneumatic converter 6213 is a double-acting cylinder, connected to an external compressed air source and a two-position five-way solenoid valve via an air pipe. When the solenoid valve coil is energized, compressed air enters the rod-side or rodless-side chamber of the cylinder, pushing the piston rod to extend or retract, thereby causing the flexible gripper 6214 to swing around its fulcrum, completing the flexible encirclement or release of the bottle body. The bottle mouth gripper 622 includes a worm gear motor 6221, two rotating shafts 6223, and two bottle mouth grippers 6225. 6221 is a DC geared motor, internally composed of a permanent magnet DC motor and a planetary gear reducer. When a DC voltage is applied to the motor terminals, the armature winding rotates under the Ampere force in the magnetic field of the permanent magnet. After gear reduction and torque amplification, the output is sent to the transmission worm 6222. Two rotating shafts 6223 are symmetrically and vertically mounted within the limiting frame 6211. A worm gear 6224 is fixedly fitted at the lower end of each rotating shaft 6223. The transmission worm 6222 is located between and meshes with the two worm gears 6224. The top of 223 extends out of the limiting frame 6211 and is fixedly installed with a bottle mouth gripper 6225. When the worm motor 6221 is powered on and rotates, the transmission worm 6222 drives the two worm wheels 6224 to rotate in opposite directions, thereby driving the two bottle mouth grippers 6225 to move towards each other to clamp the bottle mouth thread, or to move away from each other to loosen the bottle mouth. During clamping, the pneumatic conversion head 6213 is first controlled by the solenoid valve to make the flexible claw 6214 wrap around the bottle body for initial centering, and then the worm motor 6221 drives the bottle mouth gripper 6225 to clamp the bottle mouth, thus completing the double stable clamping.

[0084] The steam sterilization assembly 63 includes a transmission cylinder 631 and a synchronous guide frame 638. The transmission cylinder 631 is a double-rod type cylinder, and its cylinder body is fixed to the top of the rotating frame 614 by a hinge lug. The piston rods at both ends are respectively hinged to the fixed support on the rotating frame 614 and the lug on the synchronous guide frame 638 via the transmission shaft 632. The working principle of the double-rod cylinder is to supply air to one side of the air port and exhaust air from the other side of the air port, using the pressure difference to drive the piston and the piston rods on both sides to move synchronously. One end of the synchronous guide frame 638 is fixedly connected to a follower shaft 636, which is rotatably mounted in the rotating frame 614 via a rolling bearing. In addition, the steam sterilization assembly 633 also includes a synchronous shaft 634, which is rotatably mounted in the rotating frame 614. Inside, the synchronous shaft 634 and the hinge shaft 6212 of the limiting frame 6211 are connected by a chain belt 633. The chain belt 633 is a toothed synchronous belt. The synchronous shaft 634 is fixedly fitted with a drive gear 635, and the follower shaft 636 is fixedly fitted with a follower gear 637. The two gears mesh with each other. When the bottle or clamping assembly swings due to process requirements, the rotation of the hinge shaft 6212 is transmitted to the synchronous shaft 634 through the chain belt 633. The drive gear 635 drives the follower gear 637 and the follower shaft 636 to rotate, thereby driving the synchronous guide frame 638 to follow and move together, so that the steam nozzle 639 is facing the inside of the bottle. The steam nozzle 639 is connected to the external steam generating assembly through a gas pipe. A solenoid valve 6391 is connected in series on the gas pipe. Solenoid valve 6391 is a normally closed two-position two-way solenoid valve. When its coil is energized, the electromagnetic force pulls up the valve core to open the gas passage. When the power is off, it is closed by spring reset. At the steam sterilization station, the control system opens solenoid valve 6391, and steam is sprayed into the bottle through the nozzle. At the same time, the transmission cylinder 631 can finely adjust the angle of the synchronous guide frame 638 as needed so that the steam nozzle 639 is always aligned with the bottle opening.

[0085] The ultraviolet disinfection component 64 includes a circular multi-stage guide frame 641, a sliding rod 642, a top mounting plate 645, and a first ultraviolet disinfection lamp 646 and a second ultraviolet disinfection lamp 647. The circular multi-stage guide frame 641 is an annular cam disk fixedly mounted on the bottom frame of the disinfection device 6, with a guide groove of varying depth on its upper surface. The sliding rod 642 is slidably fitted in a linear bearing of a rotating frame 614, and a guide wheel 644 is rotatably mounted on its lower end via a connecting shaft 643. The guide wheel 644 rolls with the guide groove. The top of the sliding rod 642 is fixedly mounted on the top mounting plate 645. The first ultraviolet disinfection lamp 646 and the second ultraviolet disinfection lamp 647 are vertically mounted downwards on the bottom surface of the top mounting plate 645. The ultraviolet disinfection lamps are low-pressure mercury lamps, and the lamp tubes are filled with... The lamp contains mercury vapor. When energized, the filaments at both ends preheat and emit electrons. Under high voltage, the mercury vapor is broken down, generating an arc discharge that radiates ultraviolet light with a wavelength of 253.7nm. The circuit control is achieved by an electronic ballast and a solid-state relay. The electronic ballast provides high frequency and high voltage, and the PLC controls the on / off state of the solid-state relay to light or extinguish the lamp. When the rotating frame 614 revolves, the sliding rod 642 rotates accordingly, and the guide wheel 644 rolls along the guide groove. When it reaches the ultraviolet disinfection station, the guide wheel 644 falls into the deepest step of the groove, and the sliding rod 642 descends, allowing the ultraviolet disinfection lamp to extend into or near the bottle mouth. At this time, the solid-state relay closes, and the lamp lights up for irradiation. When it leaves the station, the guide groove becomes shallower, the sliding rod 642 rises to reset, and the lamp exits, completing the ultraviolet disinfection.

[0086] After disinfection, the bottle is picked up by the intermittent conveyor 4 on the discharge side. The structure and transmission principle of the intermittent conveyor 4 are exactly the same as those on the feed side. It is also driven by the stepper motor 42. Through the cooperation of the multi-groove guide frame 43 and the multi-groove guide frame 46, the bottle is picked up from the clamping assembly 62 and delivered forward to the intermittent feeder 5.

[0087] The interval feeder 5 includes a feeder track 51 and an interval threaded conveyor roller 53, which is installed at the end of the intermittent conveyor 4 on the discharge side. A drive motor 52 is fixed to one of its outer walls by bolts. The drive motor 52 is an AC geared motor or a servo motor. Its output shaft is fixed coaxially with the roller shaft of the interval threaded conveyor roller 53 through a coupling. The cylindrical surface of the interval threaded conveyor roller 53 is machined with continuous spiral grooves. The cross-section of the grooves matches the curvature of the bottle body. The drive motor 52 drives the interval threaded conveyor roller 53 to rotate at a uniform speed. When the bottle falls into the feeder track 51, the outer side of the bottle body is embedded in the spiral groove. The rotation of the spiral groove relies on friction to push the bottle body forward along the feeder track 51. Since the lead of the spiral groove is fixed, the bottle body is pushed forward by one lead distance for each revolution of the drive motor 52, so that the center distance between adjacent bottles remains constant. The bottles are fed into the bottle feeding station of the fully automatic capping machine one by one in an equally spaced and uniform manner.

[0088] Working principle: A batch of glass bottles enters along the placement guide rail 12 via the feeding trolley 14 of the feeding mechanism 1. After being limited in height by the height limit rope 13, the bottle stack is lifted under the drive of the hydraulic pump station and electromagnetic reversing valve of the hydraulic jacking device 17.

[0089] Each linear module of the three-axis mover 15 is driven by a stepper motor to receive pulses and drive a ball screw to perform point-to-point motion. Its two independent Z-axis output ends drive the three-jaw flexible gripper 16 and control the air circuit through a two-position five-way solenoid reversing valve to make the gripper clamp the bottle and alternately transfer it to the first input track 21 and the second input track 22 of the double-sided input mechanism 2 for release.

[0090] The bottle slides down the two chutes. At the intersection of the converging track 23, the gear and rack swing cylinder of the cylinder switching push plate 24 controls the baffle to swing according to the photoelectric sensor signal and the electromagnetic reversing valve, alternately closing one of the channels, so that the bottle flows in an orderly manner. Then, the single-phase AC geared motor drives the belt conveyor to transport the bottle forward along the converging track 23 through the capacitor phase shift.

[0091] After merging, the bottles enter the circular bottle-scraping frame 31 of the bottle unscraper 3 through the input channel 32, and fall onto the rotating circular plate 37 with a central hole driven by the servo motor 36 through the transmission chain 38. The bottles move under the action of centrifugal force and friction, and after touching the guide plate 35 fixed to the fixed shaft 34, they are gradually guided to the edge of the disc, and finally squeezed out from the output channel 33 in a single row.

[0092] After the bottle is sorted, the bottle enters the intermittent conveyor 4 on the feeding side. The conveyor wheel 411 in the conveyor track 41 supports the bottom of the bottle. The stepper motor 42 energizes each phase winding in sequence according to the pulse sequence to generate a stepping magnetic field. Through the transmission of the rotating shaft 432, the synchronous chain 45 and the meshing gear 44, the multi-groove guide frame 43 arranged on both sides rotates in the opposite direction at the same speed through a fixed indexing angle. The first flexible conveyor pad 431 attached to its groove surface alternately pushes the bottle and advances it at intervals.

[0093] At the same time, the power is transmitted to the multi-groove guide frame 46 near the disinfection device 6 through the conveyor chain 47 and the long shaft 462. The second flexible conveyor pad 461 on the groove surface of the frame moves together to send the bottles one by one into the clamping assembly 62 of the disinfection device 6.

[0094] The power component 61 of the disinfection device 6 receives a command from the rotating motor 611 to rotate, and drives the straight shaft 612 and the rotating frame 614 to revolve intermittently via the connecting chain 613;

[0095] After the bottle enters, the two-position five-way solenoid valve of the flexible gripper 621 is energized, and compressed air enters the pneumatic converter 6213 to push the piston, causing the flexible claw 6214 to swing around the hinge axis 6212 to flexibly hug the bottle body and complete the initial centering.

[0096] Subsequently, the worm motor 6221 of the bottle mouth gripper 622 is powered on. Its permanent magnet DC motor drives the transmission worm 6222 to rotate after being reduced by planetary gears. The transmission worm 6222 drives the two worm wheels 6224 to rotate in opposite directions, causing the bottle mouth grippers 6225 on the rotating shaft 6223 to move towards each other and clamp the bottle mouth.

[0097] At the steam sterilization station, the double-rod type transmission cylinder 631 of the steam sterilization component 63 drives the piston rod to extend and retract through the pressure difference between the two ends of the air port, and pulls the synchronous guide frame 638 to swing around the follower shaft 636 via the transmission shaft 632.

[0098] Meanwhile, the swing angle of the limiting frame 6211 around the hinge shaft 6212 is transmitted to the synchronous shaft 634 through the chain belt 633. The meshing of the driving gear 635 and the follower gear 637 causes the synchronous guide frame 638 to follow, so that the steam nozzle 639 installed on it is always aligned with the bottle mouth. At this time, the coil of the normally closed two-position two-way solenoid valve 6391 connected in series with the gas tube is energized, the valve core is opened, and steam is injected into the bottle to complete the thermal sterilization.

[0099] At the UV disinfection station, the circular multi-stage guide frame 641 fixed to the frame in the UV disinfection component 64 cooperates with the guide wheel 644 and the connecting shaft 643 at the lower end of the sliding rod 642 through its variable depth guide groove, forcing the sliding rod 642 to descend along the rotating frame 614, so that the first UV disinfection lamp 646 and the second UV disinfection lamp 647 on the top mounting plate 645 extend into the bottle mouth;

[0100] At the same time, the PLC controls the solid-state relay to close, and the electronic ballast lights up the ultraviolet lamp, radiating short-wave ultraviolet light to sterilize the inside of the bottle.

[0101] After disinfection, the bottles are picked up by the intermittent conveyor 4 on the discharge side in the same stepping manner and delivered forward to the intermittent feeder 5;

[0102] The drive motor 52 drives the spaced threaded conveyor roller 53 to rotate at a constant speed. The bottle falls into the continuous spiral groove embedded in the side wall of the delivery track 51 and is pushed forward by friction, so that the center distance between adjacent bottles remains constant. The bottles are sent into the bottle feeding station of the fully automatic capping machine one by one in an equal interval.

[0103] The above are merely preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
