[0034] In some embodiments, the conveyor belt transmission mechanism 200 is installed in the frame 1; the conveyor belt transmission mechanism 200 includes a rotatable first conveyor belt 23 and a rotatable second conveyor belt 24, the left and right sides of the first conveyor belt 23 and the second conveyor belt 24 are both provided with first side panels 9, the front and rear sides of the first conveyor belt 23 and the second conveyor belt 24 are both provided with second side panels 10, the bottom of the first conveyor belt 23 and the second conveyor belt 24 are both provided with conveyor belt bottom plates 13, the first side plate 9 and the conveyor belt bottom plate 13 are both fixedly connected to the second side plate 10, one end of the first conveyor belt 23 passes through one side of the frame 1, and one end of the second conveyor belt 24 passes through the other side of the frame 1.

[0035] Furthermore, the second side plate 10 on one side of the first conveyor belt 23 is fixedly connected to a motor fixing seat 15, and the motor fixing seat 15 is installed with a first motor 16.

[0036] Furthermore, the first conveyor belt 23 and the second conveyor belt 24 are arranged horizontally, and the second conveyor belt 24 is located on one side of the first conveyor belt 23; a second driving shaft 19 is installed on one side of the second side plate 10 of the second conveyor belt 24, and a second driven shaft 20 is installed on the other side of the second side plate 10 of the second conveyor belt 24, and the second driving shaft 19 and the second driven shaft 20 are connected through the second conveyor belt 24; the first driven shaft 18 and the second driving shaft 19 are coaxial, and the first driven shaft 18 and the second driving shaft 19 are connected through a coupling 22.

Among them, the first motor 16 can be a three-phase asynchronous motor.

[0038] Furthermore, the two second side plates 10 of the first conveyor belt 23 are fixedly connected with side fenders 12 above through a plurality of fixing plates 11, and the two side fenders 12 of the first conveyor belt 23 are respectively located on both sides above the first conveyor belt 23; the two second side plates 10 of the second conveyor belt 24 are fixedly connected with side fenders 12 above through a plurality of fixing plates 11, and the two side fenders 12 of the second conveyor belt 24 are respectively located on both sides above the second conveyor belt 24.

[0039] In this embodiment, the conveyor belt transmission mechanism 200 is provided with two side baffles 12 on both sides above the conveyor belt, respectively, and the empty bottles transported on the conveyor belt are shielded by the two side baffles 12 to prevent the empty bottles from falling from the conveyor belt during transportation.

[0040] Furthermore, pillars 14 are fixed below the conveyor belt bottom plate 13 , and a plurality of the pillars 14 are fixedly connected to the platform 3 .

[0041] In this embodiment, the conveyor belt transmission mechanism 200 is fixedly connected to the platform 3 of the installation mechanism 100 through a plurality of pillars 14 at the bottom thereof.

[0042] In some embodiments, the star-shaped turntable transmission mechanism 300 is installed in the frame 1; the star-shaped turntable transmission mechanism 300 includes a first star-shaped turntable 25, the lower part of the first star-shaped turntable 25 is connected to the second star-shaped turntable 26 through a plurality of turntable pads 27, a turntable shaft 28 is connected between the first star-shaped turntable 25 and the second star-shaped turntable 26, the lower part of the turntable shaft 28 passes through the table 3 and is connected to a bevel gear 30, and a motor pad 37 is installed above the bottom plate 8. A second motor 36 is fixedly mounted on the motor pad 37, and the second motor 36 is drivingly connected to a driving pulley 33, and the driving pulley 33 is connected to a driven pulley 34 through a transmission belt 35, and the driven pulley 34 is connected to a reducer 31, and the output end of the reducer 31 is connected to a bevel gear 30; a turntable support 32 is sleeved on the outer side of the turntable shaft 28, and the turntable support 32 is fixedly connected to the table 3, and the turntable support 32 is connected to the turntable shaft 28 through a bearing.

[0043] In this embodiment, the star-shaped turntable transmission mechanism 300 drives the driving pulley 33 to rotate through the second motor 36, and the driving pulley 33 drives the driven pulley 34 to rotate through the transmission belt 35. The driven pulley 34 is connected to the input end of the reducer 31, and the driven pulley 34 drives the bevel gear 30 to rotate through the reducer 31, and the bevel gear 30 drives the turntable shaft 28 to rotate, and the turntable shaft 28 drives the first star-shaped turntable 25 and the second star-shaped turntable 26 to rotate. In addition, the turntable support 32 is connected to the turntable shaft 28 through a bearing, so that the turntable shaft 28 can rotate in the turntable support 32. The turntable support 32 is fixedly connected to the table 3, and the turntable support 32 plays a supporting role, which can prevent the turntable shaft 28 from deviating during the rotation process, and ensure the stability and accuracy of the rotation of the turntable shaft 28 and the first star-shaped turntable 25 and the second star-shaped turntable 26.

[0044] Furthermore, the feed port of the first conveyor belt 23 is located on one side of the first star-shaped turntable 25 and the second star-shaped turntable 26, and the discharge port of the second conveyor belt 24 is located on one side of the first star-shaped turntable 25 and the second star-shaped turntable 26. The first star-shaped turntable 25 and the second star-shaped turntable 26 are configured to transport the empty bottles on the second conveyor belt 24 to the first conveyor belt 23 by rotating.

[0045] In this embodiment, the empty bottles enter the second conveyor belt 24 from the feed port of the second conveyor belt 24 for transportation, and the empty bottles transported on the second conveyor belt 24 enter the first star-shaped turntable 25 and the second star-shaped turntable 26 from the discharge port of the second conveyor belt 24. The first star-shaped turntable 25 and the second star-shaped turntable 26 transport the empty bottles to the feed port of the first conveyor belt 23 through rotational motion, and the first conveyor belt 23 transports the empty bottles, and finally the empty bottles are transported out from the discharge port of the first conveyor belt 23. Therefore, by rotating the first star-shaped turntable 25 and the second star-shaped turntable 26, and the layout between the first star-shaped turntable 25 and the second star-shaped turntable 26 and the first conveyor belt 23 and the second conveyor belt 24, the empty bottles can be transported from the second conveyor belt 24 to the first conveyor belt 23.

[0046] Furthermore, a plurality of evenly distributed card slots are arranged on the periphery of the first star-shaped turntable 25 and the second star-shaped turntable 26, and the card slots are used to hold empty bottles. A bottle pulling plate 29 is connected above the first star-shaped turntable 25, and the bottle pulling plate 29 is an L-shaped structure. The bottle pulling plate 29 is configured to rotate with the first star-shaped turntable 25 to transfer the empty bottles in the card slots of the first star-shaped turntable 25 and the second star-shaped turntable 26 to the first conveyor belt 23.

[0047] Furthermore, a bottle blocking ring 38 is arranged around the first star-shaped turntable 25, and the bottle blocking ring 38 is an annular opening structure. The bottle blocking ring 38 with an annular opening structure extends clockwise from one end of the discharge port of the second conveyor belt 24 to one end of the feed port of the first conveyor belt 23; the discharge port of the second conveyor belt 24 and the feed port of the first conveyor belt 23 are both located in the opening of the bottle blocking ring 38, and the bottle blocking ring 38 and the bottle pulling plate 29 are staggered.

[0048] In this embodiment, the bottle blocking ring 38 has two functions of changing the movement direction of the empty bottle and fixing the movement of the empty bottle. The size of the inner ring of the bottle blocking ring 38 matches the slot of the star-shaped turntable, which not only ensures that the empty bottles will not fall during transportation, but also ensures that the production line can transport empty bottles of different sizes, reflecting the flexible design of the filling production line.

[0049] Specifically, the second conveyor belt 24 transports the empty bottles one by one to the card slots on the outer periphery of the first star-shaped turntable 25 and the second star-shaped turntable 26, and the first star-shaped turntable 25 and the second star-shaped turntable 26 clamp the empty bottles one by one in the card slots on the outer periphery by rotating. When the first star-shaped turntable 25 drives the empty bottles to rotate to the end of the bottle blocking ring 38 close to the feed port of the first conveyor belt 23, the bottle blocking ring 38 blocks the empty bottles stuck in the card slots on the outer periphery of the first star-shaped turntable 25. At the same time, the L-shaped bottle pulling plate 29 is driven to rotate during the rotation of the first star-shaped turntable 25, and the empty bottles blocked by the bottle blocking ring 38 are transferred to the first conveyor belt 23 through the L-shaped bottle pulling plate 29. Among them, since the bottle blocking ring 38 and the bottle pulling plate 29 are staggered, the bottle pulling plate 29 does not contact the bottle blocking ring 38 during the rotation process, avoiding interference between the bottle blocking ring 38 and the bottle pulling plate 29. Therefore, the star-shaped turntable transmission mechanism 300 can smoothly transport the empty bottles clamped in the outer peripheral grooves of the first star-shaped turntable 25 and the second star-shaped turntable 26 to the first conveyor belt 23 through the cooperation between the bottle pulling plate 29 and the bottle blocking ring 38, thereby realizing the smooth transfer of the empty bottles.

[0050] Furthermore, a bottle pad plate 40 is connected to the bottom of the bottle blocking ring 38 through a plurality of bottle blocking ring pad columns 39. The bottle pad plate 40 is located below a plurality of slots on the periphery of the first star-shaped turntable 25 and the second star-shaped turntable 26. The bottle pad plate 40 is used to receive empty bottles in the slots. A bottle blocking ring support 41 is fixedly connected to the bottom of the bottle pad plate 40, and the bottle blocking ring support 41 is fixedly mounted on the table 3.

[0051] In this embodiment, the empty bottles in the outer peripheral grooves of the first star-shaped turntable 25 and the second star-shaped turntable 26 are received by the bottle pad plate 40 to prevent the empty bottles from falling. The bottle blocking ring 38 is fixed to the bottle pad plate 40, and the turntable shaft 28 passes through the hole opened in the center of the bottle pad plate 40 and is fixedly connected to the first star-shaped turntable 25 and the second star-shaped turntable 26.

[0052] Furthermore, the inner circumference of the bottle retaining ring 38 is wrapped with a protective pad, and the height of the bottle retaining ring support 41 is adjustable.

[0053] The flexible empty bottle conveying device provided in this embodiment of the present application can adapt to empty bottles of different sizes by wrapping a protective pad on the inner circumference of the bottle stop ring 38, that is, the contact point between the bottle stop ring 38 and the empty bottle, and adjusting the height of the bottle stop ring support 41, thereby effectively solving the problems that traditional filling and conveying mechanisms may encounter when conveying empty bottles of different specifications, and improving the stability and production efficiency of the production line.

[0054] In some embodiments, a rejection device 42 is fixedly installed above the bottle blocking ring 38, and the rejection device 42 includes a hydraulic cylinder 421, a hydraulic rod 422 driven and connected to the hydraulic cylinder 421, a slider 423 rotatably connected to the hydraulic rod 422, a first clamp hand 424, and a second clamp hand 425. The first clamp hand 424 and the second clamp hand 425 are arranged opposite to each other, and a slide groove 429 is provided on the side of the first clamp hand 42 away from the second clamp hand 425, and the slider 423 is slidably connected in the slide groove 429; the first clamp hand 424 is fixedly connected to the first oblique rod 4241 at the upper end facing the second clamp hand 425, and the second clamp hand 425 is fixedly connected to the second oblique rod 425 at the upper end facing the first clamp hand 424 1, the first oblique rod 4241 and the second oblique rod 4251 are rotatably connected via a first connecting rod 426; the first oblique rod 4241 is rotatably connected to a first limiting rod 4242, the second oblique rod 4251 is rotatably connected to a second limiting rod 4252, and the first limiting rod 4242 and the second limiting rod 4252 are rotatably connected via a second connecting rod 427; the first clamp hand 42 and the second clamp hand 425 are both provided with a concave surface 428 adapted to an empty bottle on the opposite side thereof, and the concave surface 428 is used to clamp the empty bottle; the rejecting device 42 is also provided with an infrared detector (not shown in the figure) for identifying unqualified empty bottles (defective products), and the second clamp hand 425 is installed on the bottle blocking ring 38 via a moving mechanism (not shown in the figure).

[0055] In this embodiment, when the empty bottle passes through the first star-shaped turntable 25, the infrared detector installed in the rejection device 42 uses infrared thermal imaging non-destructive testing technology. This technology measures the energy flow inside the object through the analysis method of infrared radiation based on the basic principle of infrared radiation, and uses an infrared thermal imager to display the detection results to visually determine the defects. When there are defects inside the object, a temperature difference will be formed between the defective area and the non-defective area of ​​the object, resulting in different infrared radiation intensities. The infrared thermal imager can be used to detect the temperature change, and then judge the defect, so as to identify whether the empty bottle is a defective product. If it is identified as a defective product, the hydraulic cylinder 421 of the rejection device 42 drives the hydraulic rod 422 to move, and the hydraulic rod 422 drives the slider 423 to slide in the slide groove 429 of the first clamp hand 424. Since the first inclined rod 4241 of the first clamp hand 424 and the second inclined rod 4251 of the second clamp hand 425 are rotatably connected via the first connecting rod 426, the hydraulic cylinder 421 drives the first clamp hand 424 to move toward the second clamp hand 425, so that the concave surface 428 of the first clamp hand 424 and the concave surface 428 of the second clamp hand 425 jointly clamp the defective empty bottle, and then the moving mechanism (not shown in the figure) between the second clamp hand 425 and the bottle blocking ring 38 drives the rejection device 42 and the unqualified empty bottles clamped by it to move, thereby realizing the removal of the unqualified empty bottles from the star-shaped turntable.

[0056] The design of the first limiting rod 4242 and the second limiting rod 4252 being rotatably connected by the second connecting rod 427 can limit the opening and closing angle between the first clamping hand 424 and the second clamping hand 425 to prevent the opening and closing angle from being too large and affecting the normal operation of the device. In addition, the end of the hydraulic cylinder 421 is fixed (not shown in the figure), and the action of the hydraulic cylinder 421 realizes the clamping or loosening of the empty bottle by the rejection device 42.

[0057] In addition, the present invention also provides a filling production line, including the above-mentioned empty bottle flexible conveying device.

[0058] The workflow of the present invention is:

[0059] Empty bottles are transported from the upstream of the production line to the second conveyor belt 24, the first motor 16 is started, driving the first conveyor belt 23 and the second conveyor belt 24 to rotate synchronously, the second conveyor belt 24 transports the empty bottles one by one to the card slots on the outer periphery of the first star-shaped turntable 25 and the second star-shaped turntable 26, and the first star-shaped turntable 25 and the second star-shaped turntable 26 rotate to card the empty bottles one by one in the card slots on the outer periphery. The first star-shaped turntable 25 drives the empty bottles to rotate, and when the empty bottles pass through the rejection device 42, the rejection device 42 automatically detects and identifies the quality of the empty bottles. If unqualified (defective) empty bottles are found, the rejection device 42 automatically rejects them from the star-shaped turntable. When the empty bottles detected by the rejection device 42 rotate to the bottle blocking ring 38 close to the feed port of the first conveyor belt 23 under the drive of the star-shaped turntable, the bottle blocking ring 38 blocks the empty bottles stuck in the outer peripheral groove of the first star-shaped turntable 25. At the same time, the L-shaped bottle pulling plate 29 is driven to rotate during the rotation of the first star-shaped turntable 25. The empty bottles blocked by the bottle blocking ring 38 are transferred to the first conveyor belt 23 through the L-shaped bottle pulling plate 29. The first conveyor belt 23 transports the empty bottles to the downstream end of the production line for filling process, thereby completing the empty bottle conveying operation.

[0060] In summary, the present invention provides a flexible conveying device for empty bottles and a filling production line, wherein a protective pad is provided at the contact point between the bottle retaining ring and the empty bottle to prevent the wear of the empty bottle due to friction during transportation; the height of the entire bottle retaining ring part can be changed by changing the height of the bottle retaining ring support, so as to adapt to the transportation of empty bottles of different sizes; the bottle retaining ring is designed as a ring-shaped opening structure, and can smoothly transfer the empty bottle to the conveyor belt in cooperation with the bottle pulling plate; the size of the inner ring of the bottle retaining ring matches the card slot of the star-shaped turntable, which not only ensures that the empty bottle will not fall during transportation, but also ensures that the production line can transport empty bottles of different sizes, reflecting the flexible design of the filling production line. In addition, the present invention adds an empty bottle rejection device, while the traditional filling and conveying mechanism does not have an empty bottle rejection device, which may lead to two undesirable operating conditions: one is that when the size of the empty bottle is incorrect, it will cause the turntable to fail, and the empty bottles will pile up on the empty bottle conveying line, causing a burden on the production line; the other is that the defective empty bottles in the empty bottle filling process lead to inconsistent expected filling time, thereby affecting product quality and production time, and causing waste of resources. The rejection device provided by the present invention can effectively reject unqualified empty bottles, effectively solving the problems that the traditional filling and conveying mechanism may encounter when conveying empty bottles of different specifications, improving the stability and production efficiency of the production line, reducing equipment failure rate and resource waste, and providing strong support for the sustainable development of beverage production enterprises.
