Description

[0002] In the production process of a bottle blowing machine, the plastic bottles after blow molding usually need to be cleaned to meet the quality standards. At present, there are mainly two ways to clean the plastic bottles: one way is to use water to clean, which wastes water resources and is time-consuming and low in efficiency; the other way is to use air to clean the inner cavity of the glass bottle, which can not only save water resources, reduce the cleaning process and reduce production costs.

[0003] In the prior art, the air cleaning method generally places a single plastic bottle on the bottle blowing machine by manual operation, and uses high-pressure airflow to clean the inside of the plastic bottle. However, this method not only has low work efficiency, but also the dust directly blown out is easy to scatter in the air, which not only easily leads to the operator inhaling dust and affects the health, but also may be attached to the cleaned bottle again, reducing the cleaning effect and affecting the product quality.

[0034] The following will be described in detail in combination with the accompanying drawings Figures 1-7 Further detailed description will be made on an embodiment of the present application.

[0035] An automatic bottle washing machine, as shown in the drawings, comprises a feeding device 1 for feeding plastic bottles, a sorting device 2 arranged at the end of the feeding device 1 for sorting plastic bottles, and a cleaning device 3 connected to one side of the discharge end of the sorting device 2 for cleaning the inner wall of the bottle body. Figure 1 , 2 The cleaning device 3 comprises a machine box 31, a conveying belt 32 arranged on the machine box 31 for conveying plastic bottles, a turnover mechanism 33 arranged on one side of the conveying belt 32 for turning the bottle mouth of the plastic bottle downward, and an air flow flushing mechanism 34 cooperating with the turnover mechanism 33 for air flow cleaning of the inner cavity of the bottle body. One end of the turnover mechanism 33 is drivingly connected with a first lifting driving mechanism 4, and the other end is drivingly connected with a positioning and clamping mechanism 5. The air flow flushing mechanism 34 is arranged corresponding to the position after the turnover of the turnover mechanism 33, and the bottom end of the air flow flushing mechanism 34 is drivingly connected with a second lifting driving mechanism 6. The second lifting driving mechanism 6 is connected with the first lifting driving mechanism 4 in cooperation, so that the turnover mechanism 33 and the air flow flushing mechanism 34 can adjust the cleaning position synchronously according to the specifications of the plastic bottle.

[0036] Specifically, the turnover automatic bottle washing machine first enters the plastic bottles into the sorting device 2 through the feeding device 1 when working, then sorts and arranges the plastic bottles by the sorting device 2, and then transports them to the conveying belt 32 of the cleaning device 3. Finally, the cleaning device 3 realizes automatic feeding, sorting and arranging and efficient cleaning of the plastic bottles through the cooperation of the positioning and clamping mechanism 5, the turnover mechanism 33, the airflow washing mechanism 34 and the corresponding lifting driving mechanism, which not only reduces the labor intensity, but also greatly improves the cleaning efficiency. The positioning and clamping mechanism 5 can batch clamp the plastic bottles on the conveying belt 32, and drive the plastic bottles to overturn through the turnover mechanism 33 to make the bottle mouth downward, while the first lifting driving mechanism 4 drives the overturned plastic bottles to move downward, and the second lifting driving mechanism 6 drives the airflow washing mechanism 34 to move upward, so that the airflow washing mechanism 34 can adjust the cleaning position according to the specifications of the plastic bottles. In addition, the airflow washing mechanism 34 adopts the way of blowing and sucking at the same time, which not only avoids the dust from escaping in the air, but also improves the cleaning effect.

[0037] In the embodiment, as shown in Figures 4 to 8 The airflow washing mechanism 34 includes a plurality of air blowing pipes 341, a suction air base 342, an air suction pipe 343 and a dust collecting tank 344. The air blowing pipes 341 are provided with a plurality of air blowing pipes 341, and the outer sides of the plurality of air blowing pipes 341 are sleeved with ultraviolet germicidal lamps 345; the bottom end of the air blowing pipe 341 is fixedly installed on the suction air base 342 and is communicated with the outside air source through the air pipe, and the top end of the air blowing pipe 341 is provided with an air blowing hole 3411 communicated with the air source; the suction air base 342 is fixedly connected to the second lifting driving mechanism 6, and the suction air base 342 is communicated with the dust collecting tank 344 through the air suction pipe 343. The suction air base 342 has a suction cavity 3421 matched with the bottle mouth, and the bottom end of the suction cavity 3421 is provided with an air suction hole 3422 communicated with the air suction pipe 343.

[0038] Specifically, when the plastic bottle is flipped 180° by the flipping mechanism 33 so that the bottle opening faces downwards, the first lifting drive mechanism 4 moves the flipped plastic bottle downwards, and the second lifting drive mechanism 6 moves the airflow flushing mechanism 34 upwards. These two mechanisms work together to ensure that the suction chamber 3421 of the suction base 342 accurately covers the bottle opening. At this time, an external air source introduces high-pressure gas into the blowing pipe 341 through the air pipe. The high-pressure gas is blown out from the blowing hole 3411 at the top of the blowing pipe 341. The blown gas can lift dust, particulate matter, and other foreign objects from the inner wall of the plastic bottle, suspending them inside the bottle. Simultaneously, due to the negative pressure created within the suction chamber 3421 of the suction base 342, the dust and foreign objects suspended inside the plastic bottle are drawn into the suction chamber 3421 through the suction hole 3422 under the negative pressure, and then sucked into the dust collection tank 344 through the suction pipe 343. This method of blowing and suction simultaneously effectively removes dust and foreign objects from the inner wall of plastic bottles, preventing dust from escaping into the air and protecting the health of operators. Furthermore, for larger particles, the high-pressure gas can blow them off and suck them into the dust collection tank 344; and for any moisture remaining in the inner cavity of the plastic bottle after washing, the high-pressure gas can also dry it, greatly improving cleaning efficiency and effectiveness.

[0039] It is worth mentioning that while the air blowing tube 341 blows air, the ultraviolet germicidal lamp 345 located outside the air blowing tube 341 is activated simultaneously. The emitted ultraviolet light can further sterilize and disinfect the inner cavity of the bottle, thereby improving the dual cleaning effect on the plastic bottle.

[0040] In this embodiment, as Figure 9 As shown, the flipping mechanism 33 includes a flipping motor 331, a rotating shaft 332, and a synchronous belt assembly 333. The output end of the flipping motor 331 is connected to the synchronous belt assembly 333 for transmission, and the flipping motor 331 is fixedly mounted on the first lifting drive mechanism 4; the rotating shaft 332 is horizontally arranged along the conveying direction of the conveyor belt 32, and one end of the rotating shaft 332 is linked to the synchronous belt assembly 333, while the other end is provided with a bearing seat 334.

[0041] Specifically, when the plastic bottle is conveyed to the lower side of the positioning and clamping mechanism 5 by the conveying belt 32, the positioning and clamping mechanism 5 fixes the plastic bottle; at this time, the overturning motor 331 is started, and the rotating shaft 332 is driven to rotate through the synchronous belt assembly 333. Since the rotating shaft 332 is linked with the positioning and clamping mechanism 5, the rotation of the rotating shaft 332 will drive the positioning and clamping mechanism 5 and the clamped plastic bottle to overturn together, so that the plastic bottle is overturned by 180° with the bottle opening downward; after being washed by the airflow washing mechanism 34, the overturning mechanism 33 overturns the bottle body to reset, so that the cleaned bottle body is conveyed out of the material by the conveying belt 32 again. In this overturning process, the overturning motor 331 provides stable power output, the synchronous belt assembly 333 ensures effective power transmission, and the rotating shaft 332 can rotate stably under the support of the bearing seat 334, so as to ensure that the plastic bottle can be accurately and stably overturned to the appropriate angle. The overturning mechanism 33 is simple and reliable in design, and can quickly realize the overturning action of the plastic bottle, thereby creating conditions for the subsequent dust cleaning work.

[0042] In the embodiment, as shown in Figure 9 The positioning and clamping mechanism 5 is arranged above the conveying belt 32, and is used for fixing and clamping the arranged plastic bottles; the positioning and clamping mechanism 5 includes a clamping frame 51, a positioning block 52 and a cylinder driving assembly 53. The clamping frame 51 is provided with at least two groups, and the two groups of clamping frames 51 are symmetrically arranged. The two ends of the clamping frame 51 are in transmission connection with the cylinder driving assembly 53. The positioning block 52 is provided with a plurality of positioning blocks 52, which are equidistantly arranged on the inner side of the clamping frame 51. One side of the positioning block 52 is fixed to the clamping frame 51, and the other side is provided with an arc-shaped groove 521 matched with the bottle body. The cylinder driving assembly 53 is in linkage connection with the overturning mechanism 33.

[0043] Specifically, the cylinder driving assembly 53 includes an L-shaped connecting plate 531, a transmission shaft 532 transversely penetrating the L-shaped connecting plate 531, and a driving cylinder 533 for driving the transmission shaft 532 to rotate. One end of the L-shaped connecting plate 531 is fixed to the overturning mechanism 33, and the other end is connected with the transmission shaft 532. The transmission shaft 532 is slidably connected with a bearing fixed seat 534, and the bearing fixed seat 534 is fixedly connected with the limiting frame 72. The driving cylinder 533 is fixed to the L-shaped connecting plate 531, and the output end of the driving cylinder 533 is in transmission connection with the transmission shaft 532.

[0044] When the plastic bottle is conveyed to below the positioning and clamping mechanism 5, the driving cylinder 533 is started, and the output end of the driving cylinder 533 drives the transmission shaft 532 to rotate. The transmission shaft 532 is provided with a cam profile or eccentric wheel, and the bearing fixing seat 534 is in contact with the cam profile or eccentric wheel; when the transmission shaft 532 rotates, the cam profile or eccentric wheel pushes the bearing fixing seat 534 to slide in the axial direction, thereby driving the clamping frame 51 to move to the middle. Since the arc-shaped groove 521 inside the positioning block 52 is matched with the bottle body, when the clamping frame 51 moves, the positioning block 52 can accurately clamp the bottle body of the plastic bottle, so as to realize the fixed clamping of the plastic bottle. At the same time, since the cylinder driving assembly 53 is connected with the turnover mechanism 33 in linkage, after the plastic bottle is fixed, the turnover mechanism 33 can drive the positioning and clamping mechanism 5 and the plastic bottle to perform a turnover action together. This positioning and clamping mechanism 5 can quickly and accurately clamp the plastic bottle, and realizes automatic operation through cylinder driving, thereby improving the work efficiency. In addition, the arc-shaped groove 521 of the positioning block 52 is designed to better fit the plastic bottle body, so as to ensure the stability of clamping and avoid the situation that the plastic bottle is loose or falls off during turnover and cleaning.

[0045] In the present embodiment, as shown in Figure 9 The first lifting driving mechanism 4 includes a first lifting support 41, a first transmission lead screw 42, a first guide plate 43 and a first motor 44. The first lifting support 41 is fixed to the cabinet 31 and is composed of a first guide column 411 and a first fixed plate 412. The first guide column 411 is vertically fixed to the cabinet 31, and the first fixed plate 412 is arranged at the top of the first guide column 411. The first transmission lead screw 42 is located between two adjacent first guide columns 411, and one end of the first transmission lead screw 42 penetrates out of the first fixed plate 412. The first guide plate 43 is arranged transversely on the first lifting support 41, and a first ball nut seat 45 is connected between the first guide plate 43 and the first transmission lead screw 42. The first motor 44 is fixedly installed on the first fixed plate 412, and the output end of the first motor 44 is in transmission connection with the first transmission lead screw 42.

[0046] Specifically, in operation, the first motor 44 is started, and the output end of the first motor 44 drives the first transmission screw 42 to rotate. Since the first guide plate 43 is connected with the first transmission screw 42 through the first ball nut seat 45, the rotation of the first transmission screw 42 drives the first ball nut seat 45 to move along the axial direction of the first transmission screw 42, thereby driving the first guide plate 43 to move up and down on the first lifting support 41. Since the turnover mechanism 33 is fixedly installed on the first lifting support 41, the up-and-down movement of the first guide plate 43 drives the turnover mechanism 33 and the plastic bottle clamped thereby to move up and down together; the first guide column 411 provides a guide for the movement of the first guide plate 43, thereby ensuring the stability and accuracy of the first guide plate 43 in the movement process. By controlling the rotation direction and speed of the first motor 44, the lifting position of the turnover mechanism 33 and the plastic bottle can be accurately adjusted, so that the turnover mechanism 33 and the plastic bottle can be accurately matched with the airflow flushing mechanism 34 to complete the cleaning work.

[0047] In the embodiment, as shown in Figure 6 the second lifting drive mechanism 6 includes a second lifting support 61, a second transmission screw 62, a second guide plate 63 and a second motor 64. The second lifting support 61 is fixed to the cabinet 31, and the second lifting support 61 is composed of a second guide column 611 and a second fixed plate 612. The second guide column 611 is fixed vertically on the cabinet 31, and the second fixed plate 612 is arranged at the top of the second guide column 611. The second transmission screw 62 is located between two adjacent second guide columns 611, and one end of the second transmission screw 62 penetrates out of the second fixed plate 612. The second guide plate 63 is arranged transversely on the second lifting support 61, and the second guide plate 63 is connected with the second transmission screw 62 through a second ball nut seat 65. The second motor 64 is fixedly installed on the second fixed plate 612, and the output end of the second motor 64 is in transmission connection with the second transmission screw 62.

[0048] Specifically, the working principle of the second lifting drive mechanism 6 is similar to that of the first lifting drive mechanism 4. When the second motor 64 is started, the output end of the second motor 64 drives the second transmission screw 62 to rotate, and the second transmission screw 62 drives the second guide plate 63 to move up and down on the second lifting support 61 through the second ball nut seat 65. Since the airflow flushing mechanism 34 is fixedly connected to the second lifting support 61, the up-and-down movement of the second guide plate 63 drives the airflow flushing mechanism 34 to move up and down. The second guide column 611 provides a guide for the movement of the second guide plate 63, thereby ensuring the stability and accuracy of the airflow flushing mechanism 34 in the movement process. The first lifting drive mechanism 4 and the second lifting drive mechanism 6 cooperate with each other, can accurately adjust the relative position between the airflow flushing mechanism 34 and the plastic bottle according to the specifications of the plastic bottle, and ensure that the airflow flushing mechanism 34 can smoothly extend into the plastic bottle and complete the cleaning work, thereby improving the adaptability of the bottle washing machine to plastic bottles of different specifications.

[0049] In the embodiment, as shown in Figure 7 the conveying belt 32 transversely penetrates both sides of the machine box 31 for conveying plastic bottles; the limiting assembly 7 includes a fixed support 71, a limiting support 72 and a locking knob 73, the fixed support 71 is installed on both sides of the conveying belt 32, and a mounting hole is formed in the fixed support 71; one side of the limiting support 72 is movably connected with the fixed support 71 through a connecting rod 721 penetrating the mounting hole, and the other side is provided with a limiting baffle 722; the locking knob 73 is threadedly connected to the top end of the fixed support 71, and one end of the locking knob 73 abuts on the connecting rod 721.

[0050] Specifically, in actual installation and use, the distance between the two limiting baffles 722 can be changed by adjusting the position of the limiting support 72 according to the specifications of the plastic bottles. The specific operation is to loosen the locking knob 73, move the limiting support 72 along the connecting rod 721 in the mounting hole to the appropriate position, and then tighten the locking knob 73 to fix the limiting support 72. In this way, the limiting baffles 722 can limit and fix the plastic bottles on the conveying belt 32, preventing the plastic bottles from deviating or falling during the conveying process, and ensuring that the plastic bottles can accurately reach the subsequent processing position. At the same time, this adjustable limiting assembly 7 can adapt to plastic bottles of different specifications, improving the versatility of the bottle washing machine.

[0051] It should be noted that the position of the conveying belt 32 corresponding to the clamping frame 51 of the positioning and clamping mechanism 5 is not provided with the limiting assembly 7, which is to avoid the collision between the clamping frame 51 and the limiting support 72 during the clamping action. At this position, the positioning and prevention of lateral shift / falling of the plastic bottles mainly rely on the positioning and clamping mechanism 5 itself which is about to act.

[0052] In the embodiment, as shown in Figure 3 the feeding device 1 includes a hopper 11 and an elevator 12, the hopper 11 adopts a conical structure, which helps the plastic bottles to smoothly converge to the bottom of the hopper 11, facilitating the grabbing and conveying of the elevator 12; at the same time, the hopper 11 is arranged at the bottom end of the elevator 12, which can stably receive the plastic bottles; a plurality of material blocking plates 121 are equidistantly arranged on the surface of the conveying belt of the elevator 12, and a discharging track 122 is connected to the end of the elevator 12.

[0053] Specifically, during the actual feeding process, the plastic bottles are manually poured into the hopper 11 and will naturally slide to the bottom of the hopper 11 due to the action of gravity. After the elevator 12 is started, the conveying belt of the elevator 12 drives the baffle plate 121 to move upward, and the baffle plate 121 will clamp the plastic bottles and convey them upward. When the plastic bottles are conveyed to the top end of the elevator 12, they will slide into the sorting device 2 along the discharging track 122 at the end of the elevator 12 under the action of gravity and the pushing force of the conveying belt. This feeding mode realizes automatic feeding of the plastic bottles, reduces manual intervention, and improves production efficiency. At the same time, the setting of the baffle plate 121 ensures the stability of the plastic bottles during the conveying process, avoiding the situation of sliding or piling up of the plastic bottles.

[0054] In the embodiment, as shown in the figure, Figure 3 The sorting device 2 includes a barrel 21, a rotating disc 22 and a feeding track 23. The rotating disc 22 is arranged in the barrel 21, and a plurality of mounting stations 221 for accommodating plastic bottles are circumferentially distributed on the rotating disc 22. The feeding track 23 is located on one side of the rotating disc 22 and communicates with the barrel 21, and the discharging end of the feeding track 23 is connected with the conveying belt 32. A plurality of mounting stations 221 for accommodating plastic bottles are circumferentially distributed on the rotating disc 22, and a servo motor is drivingly connected to the bottom end of the rotating disc 22.

[0055] Specifically, after the plastic bottles fall into the barrel 21 from the elevator 12, the servo motor arranged at the bottom of the rotating disc 22 drives the rotating disc 22 to rotate, so that the plastic bottles accurately fall into the mounting stations 221 during the rotation. With the continuous rotation of the rotating disc 22, the mounting stations 221 with plastic bottles will rotate to one side of the feeding track 23. At this time, under the action of gravity and the centrifugal force generated by the rotation of the rotating disc 22, the plastic bottles will slide from the mounting stations 221 into the feeding track 23, thereby completing the sorting and feeding of the plastic bottles, and sliding along the feeding track 23 to the conveying belt 32 of the cleaning device 3, preparing for the subsequent cleaning work.

[0056] It is worth mentioning that the actions of the above-mentioned mechanisms are controlled by a PLC program, and a photoelectric sensor is arranged to detect the position of the bottles and trigger the corresponding driving motor. For different specifications of bottles, parameters can be input through a man-machine interface, so that the bottle washing machine can automatically adjust the parameters such as the overturning angle, the lifting height, the blowing pressure, etc., to realize flexible production.

[0057] The working principle of the present application is as follows:

[0058] The turnover automatic bottle washing machine works, the plastic bottle first gathers through the conical hopper 11, and the blocking plate 121 of the elevator 12 is obliquely transported to the material arranging device 2, the installation position 221 of the rotating disc 22 cooperates with the servo motor to sort the bottle and send it into the feeding track 23. The bottle slides along the track to the conveying belt 32 of the cleaning device 3, the spacing is adjusted and the bottle body is fixed by the limiting assembly 7. The positioning and clamping mechanism 5 drives the clamping frame 51 to clamp the bottle, the turnover motor 331 drives the rotating shaft 332 through the synchronous belt assembly 333 to make the bottle turn over 180° to the bottle mouth downward, the first lifting driving mechanism 4 drives the turned over bottle to descend, and the second lifting driving mechanism 6 makes the airflow flushing mechanism 34 rise, so that the air suction cavity 3421 is accurately connected with the bottle mouth. At this time, the external air source supplies air to the air blowing pipe 341, the high-pressure gas is sprayed from the air blowing hole 3411 to strip the dust on the bottle wall, the dust-containing airflow is sucked into the dust collecting tank 344 by the air suction cavity 3421 under negative pressure, the cleaning by blowing and sucking is completed, and after cleaning, the mechanisms are reset, and the bottle is sent out with the conveying belt 32.

Therefore: any equivalent changes made according to the structure, shape and principle of the application should be covered by the protection scope of the application.
