Description

Technical Field

[0001] The invention relates to the technical field of waste material recycling, in particular to an online plastic recycling device for capsule medicine plate production. Background Art

[0002] As a primary form of pharmaceutical packaging, capsule sheets are seeing increasing consumption annually. In response to the call for resource recycling, the industry has begun exploring the use of recycled materials from used packaging bottles to produce capsule sheets. However, the labeling of used bottles presents a key obstacle in the recycling process: these labels are typically made of PVC, PE film, or paper, and are attached with self-adhesive or composite adhesives. Residual adhesive can easily form impurities during the recycling process. Furthermore, if not thoroughly cleaned, the adhesive releases volatile organic compounds during high-temperature processing, leading to excessive levels of heavy metals in the recycled material, compromising the sealing properties of the sheets and the safety of the medication.

[0003] Existing cleaning equipment primarily uses a single friction method to clean bottle labels. This method can easily damage the bottle surface, generate microplastics, and increase the burden of subsequent filtration. Furthermore, cleaning equipment primarily targets round bottles and cannot effectively clean the flat surface of square bottles, resulting in a limited range of applications. Summary of the Invention

[0004] The purpose of the present invention is to provide an online plastic recycling device for capsule medicine plate production to solve the problems raised in the prior art.

[0005] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: an online plastic recovery device for capsule medicine plate production, comprising a box body provided with a feed port and a discharge port, a power cylinder provided above the box body, the power cylinder driving the end plate inside the box body to move up and down, a partition, a guide plate and at least two diverter plates provided inside the box body, the diverter plate being installed on the partition, the guide plate guiding the packaging bottle between two adjacent diverter plates, at least two rubbing plates provided on the end plate, two rubbing plates distributed between two adjacent diverter plates, one end of the two rubbing plates located between the two adjacent diverter plates being commonly connected to a reciprocating mechanism, the two rubbing plates cooperating with each other to remove the bottle labels or labels on the surface of the packaging bottle by scraping or rubbing.

[0006] The diverter plate is hollow and is equipped with a small submersible pump and a water pressure sensor. The partition is provided with multiple flow channels that connect to the internal space of the diverter plate. The small submersible pump is connected to the multiple flow channels via a multi-way pipe. The small submersible pump pumps water into the diverter plate or below the partition. Retractable side bladders are provided on both sides of the diverter plate. These side bladders expand outward or contract under the water pressure within the diverter plate or the housing. The side bladders are located between the washboard and the diverter plate. The washboard is moved linearly by a reciprocating mechanism. A multi-way pipe (not shown) is connected to the inlet and outlet of the small submersible pump. Valves are installed at the mouths of the multi-way pipe to facilitate the operation of the small submersible pump, enabling the small submersible pump to pump water into the diverter plate or extract water from the diverter plate and deliver it below the partition.

[0007] The partition is provided with at least one step, located between the two washboards. The step has rounded corners and is hollow. One end of the step is triangular, and a gate plate is rotatably mounted on the inside of the other end. A gate cylinder is rotatably mounted inside the step. The cylinder rod of the gate cylinder is rotatably connected to one end of the gate plate. The other end of the gate plate has a notch in the middle, and a sensor for monitoring the bottle is mounted on the gate plate. Before the bottle passes between the two washboards, the cylinder rod of the gate cylinder extends, pushing the gate plate into a vertical position, causing one end of the gate plate to stand upright between the two washboards, preventing the bottle from flowing directly between the two washboards. When the bottles flow between the two side bags under the influence of the water flow, they are intercepted by the vertical gate plates. After that, the power cylinder drives the end plate down to a certain height, so that the two washboards fall between the two diverter plates and are outside the bottles. Then the small submersible pump starts to work, extracting the water under the partition and pumping it into the diverter plates. As the pressure in the diverter plates increases, the side bags stretch outward under the action of the water pressure and gradually squeeze the washboards, so that the washboards fit the surface of the bottles. When the water pressure detected by the water pressure sensor reaches the set value, the small submersible pump stops working, and then the power cylinder works again and pushes the washboards down again, so that the washboards fit the surface of the bottles. To scrape off the bottle labels or stickers from the outside, a power cylinder lowers the washboard to a certain height. A small submersible pump pumps water from the manifold to below the bulkhead, causing the side bladders to contract under the water pressure in the chamber. This causes the washboard spring to reset and separate from the bottle. Once the washboard is separated from the bottle, the power cylinder returns the washboard to its pre-descent height (i.e., between the two manifolds). The small submersible pump then pumps water from below the bulkhead back into the manifold, causing the side bladders to expand and squeeze the washboard, forcing it to re-adhere to the bottle's outer surface. After repeated scraping operations, the bottle labels or stickers are completely removed. Once the labels are completely removed, the side bladders contract under the water pressure, causing the washboard to reset under the power cylinder. The gate cylinder's rod retracts, causing the gate plate to gradually tilt under the cylinder until the bottle, carried by the water flow, passes over it. Once the sensor detects the bottle has passed over, the gate cylinder pushes the gate plate back to its vertical position to intercept the next bottle.

[0008] The reciprocating mechanism includes a bracket symmetrically mounted on the end plates, each of the brackets being rotatably mounted with a telescopic rod at both ends, a spring supporting telescopic reset is mounted inside the telescopic rod, so that the two ends of the telescopic rod are reset after telescoping, the two telescopic rods are connected by a coupling shaft, a connecting plate is rotatably mounted between the telescopic ends of the two telescopic rods, a slide groove is symmetrically arranged on the end plates, the connecting plate is located in the slide groove, sliders are mounted on both sides of the connecting plate, a notch is respectively arranged on two parallel end surfaces of the slider, and the two notches are in a perpendicular relationship, one notch is slidably connected to the connecting plate, and the other notch is slidably connected to the slide groove, and one end of the connecting plate is connected to the washboard; A crankshaft is disposed between the two brackets and is rotatably connected to the coupling via a shaft plate. One end of the crankshaft is connected to a drive cylinder. The drive cylinder is a rotary hydraulic cylinder. Driven by the drive cylinder, the crankshaft, via the shaft plate, drives the coupling. As the crankshaft rotates, one end of the two telescopic rods performs reciprocating linear motion in the vertical direction, thereby causing the two washboards to move toward each other in the vertical direction. This movement of the washboards removes the bottle labels or labels from the bottle surfaces by rubbing. When rubbing is not required, the drive cylinder uses the crankshaft to horizontally position the telescopic rods, aligning the two ends of the telescopic rods at the same height, allowing the power cylinder to drive the two washboards to scrape the bottle labels or labels from the bottle surfaces. Under the constraints of the slider, when the washboards are squeezed by the side bags, they can move horizontally within the chute, carrying the washboards with them, preventing the chute from tilting.

[0009] The washboard is provided with a plurality of files, and spring grooves are provided on the narrow sides of the washboard. A "C"-shaped pressure frame and a compression spring are slidably installed in the spring grooves. One end of the compression spring rests on the pressure frame, and the other end rests on the cover plate that closes the spring groove. When the power cylinder drives the washboard down, the pressure frame first rests on the outside of the packaging bottle. After the washboard is lowered to a certain height by the power cylinder, the pressure frame presses the packaging bottle on the step, fixing the position of the packaging bottle and facilitating the subsequent labeling or bottle label removal of the packaging bottle. After the pressure frame presses the packaging bottle on the step, as the washboard moves downward, the pressure frame moves in the spring groove and compresses the compression spring. When the washboard is raised by the power cylinder, the pressure frame still rests on the outside of the packaging bottle under the action of the compression spring.

[0010] The washboard is provided with multiple recesses extending through the washboard. The file is slidably mounted within the recesses via a return spring. The length of the file within the recesses is less than the thickness of the washboard. Two arc-shaped scraping grooves of different diameters are provided at one end of the file, transitioning between them via a curved surface. The lower scraping groove has a larger diameter than the upper scraping groove. The scraping grooves are provided with file teeth, and the curved surface is provided with a downwardly angled blade. One end of the return spring is connected to the recesses, and the other end is connected to the file. When the side bladders expand and contract, portions of the side bladders squeeze into the recesses, pushing the file out of the recesses, causing the file's blade to contact the outer surface of a bottle (a square bottle or mineral water bottle) or for the scraping grooves to contact the outer surface of the bottle (a mineral water bottle). When the scraping grooves contact the outer surface of the bottle, the two washboards are of equal height, and the files of equal height are butted together under the pressure of the side bladders. The washboards drive the files downward, and the file's blades or scraping grooves are used to remove bottle stickers or labels from the outer surface of the bottle. When removing the bottle sticker or label from the outer surface of the mineral water bottle, since the scraping groove is attached to the outer surface of the packaging bottle, when the scrubbing board descends, the file can use the scraping groove to smoothly follow the curve of the mineral water bottle to tear off or scrape off the bottle sticker or label from the outer surface of the mineral water bottle.

[0011] Inside the box, a guide plate is installed at the feed inlet. One end of the bent guide plate is connected to a partition. A water outlet trough is provided on the guide plate to impact the packaged bottles. One end of the partition is tilted to form an interceptor plate. This interceptor plate is provided with a separation trough for the labels or bottle labels to pass through. The labels or bottle labels are carried through the separation trough by water. A submersible pump for driving water circulation is installed in the space formed by the partition, guide plate, and box. The submersible pump draws water from the source below the partition and discharges it from the water outlet trough. The operation of the submersible pump causes water to circulate within the box, flowing from the water outlet trough and back through the diversion trough.

[0012] A retractable water bladder is located below the partition. The outlet of the submersible pump is connected to a tee via an output pipe. One of the ends of the tee is connected to a bladder outlet pipe, which is connected to the water bladder. The inlet of the submersible pump is connected to a bladder inlet pipe and a water pump via a tee. The inlet of the water pump is equipped with an anti-blocking net. A retractable filter is slidably mounted on the bottom of the box. Bottle labels or tags follow the water flow through the diversion trough, concentrating them below the partition. When it is necessary to clean the bottle stickers or labels, the submersible pump starts working, pumping water through the suction pipe and pumping the water into the water bag through the bag outlet pipe. As the water enters, the water bag gradually expands, and 95% of the water in the box is infused into the water bag. After that, the submersible pump stops working, and the operator removes the filter from the box and gradually pulls it out. During the pumping process, the remaining water mixed with some bottle stickers or labels flows out of the box, and most of the bottle stickers or labels remain on the filter. The filter is then cleaned. After the filter is cleaned, it is pushed back into the box and fixed with bolts.

[0013] Inside the box, a screen plate is rotatably mounted on one side of the discharge port via a shaft. One end of the shaft is connected to a motor. The screen plate is provided with multiple mesh slots, with a recessed plate seat located at the end of the slots away from the shaft. A sleeve plate is slidably mounted on the screen plate. A secondary slot is provided on the sleeve plate corresponding to the slots, and a triangular set plate is located at the end of the secondary slot near the shaft. The set plate is positioned within the slots. The sleeve plate is sleeved onto the screen plate and slidably connected to the screen plate via the set plate. A motor (not shown) drives the shaft to rotate, causing the screen plate to rotate within the box. When the sleeve plate is initially below the horizontal plane of the shaft, under its own weight, it slides on the screen plate and to the end away from the shaft. This sliding action increases the screen plate's operating area, facilitating the screen plate's removal of bottle labels or labels near the interceptor plate from the box. When the sleeve plate is initially above the horizontal plane of the shaft, it slides toward the shaft under its own weight, reducing its length and facilitating its rotation within the box. When the sleeve plate slides on the mesh plate, the bottle labels or labels blocked in the mesh slot and auxiliary slot are cleaned through the triangular plate and the plate seat.

[0014] The box is provided with a toggle lever, located below the guide plate and in front of the diverter plate. The toggle lever is used to reduce the flow space of the bottles, reducing the probability of the bottles entering the space between the two washboards in a vertical position. The toggle lever blocks the bottles, forcing them to flow horizontally between the two washboards.

[0015] Compared with the prior art, the present invention has the following beneficial effects: 1. Through the structural settings of the washboard, file and side bags, it is possible to remove bottle labels not only from square packaging bottles, but also from mineral water bottles, and even from square packaging bottles and mineral water bottles at the same time. It not only realizes the cleaning of bottle labels of multiple types of packaging bottles, but also realizes the cleaning of bottle labels of different types of packaging bottles at the same time, thereby improving the cleaning efficiency of packaging bottles and expanding the scope of application of cleaning packaging bottles.

[0016] 2. The washboard, file, and reciprocating mechanism work together to not only scrape off bottle labels but also rub them off, depending on the needs and control of the controller. Scraping or rubbing provides multiple methods for label removal, achieving diverse cleaning options and improving label removal effectiveness. The targeted force of scraping or rubbing directly peels off the label, preventing the generation of microplastics during the removal process.

[0017] 3. The file is provided with a scraping groove, which can adapt to the curved surface of the packaging bottle through the arc-shaped scraping groove, thereby increasing the coverage area of ​​the file on the packaging bottle and improving the cleaning efficiency of the bottle label.

[0020] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0021] Example: Figure 1 - Figure 11 As shown, the present invention provides a technical solution, an online plastic recovery device for capsule medicine plate production, comprising a box body 1 provided with a feed port and a discharge port, a power cylinder 2 provided above the box body 1, the power cylinder 2 being a hydraulic cylinder, the power cylinder 2 driving the end plate 16 inside the box body 1 to move up and down, a partition 6, a guide plate 9 and five diverter plates 12 provided inside the box body 1, two of the diverter plates 12 located on the outside are connected to the inner wall of the box body 1, a guide rod 14 is installed above the two diverter plates 12 located on the outside, the guide rod 14 passes through the end plate 16 and the box body 1, the end plate 16 is slidably connected to the guide rod 14, the diverter plate 12 is installed on the partition 6, and the guide plate 9 guides the packaging bottle into the space between two adjacent diverter plates 12. Eight rubbing plates 11 are provided on the end plate 16, and two rubbing plates 11 are distributed between two adjacent diverter plates 12. One end of the two rubbing plates 11 located between the two adjacent diverter plates 12 is commonly connected to a reciprocating mechanism. The two rubbing plates 11 cooperate with each other to remove the bottle stickers or labels on the surface of the packaging bottles by scraping or rubbing.

[0022] Inside the box 1, a guide plate 5 is installed at the feed inlet. One end of the bent guide plate 5 is connected to a partition 6. A water outlet trough is provided on the guide plate 5, which impacts the packaged bottles. One end of the partition 6 is tilted to form an interceptor plate 13. Interceptor plate 13 is provided with a separation trough for labels or bottle labels to pass through. The labels or bottle labels are carried through the separation trough by the water. A submersible pump (not shown) that drives water circulation is installed in the space formed by the partition 6, guide plate 5, and box 1. The submersible pump draws water from the source below the partition 6 and discharges it through the outlet trough. The operation of the submersible pump causes water to circulate within the box 1, flowing from the outlet trough and back through the diversion trough.

[0023] A retractable water bladder 7 is located below the partition 6. The outlet of the submersible pump is connected to a tee via an output pipe 74. One of the ends of the tee is connected to an outlet pipe 73, which is in turn connected to the water bladder 7. The inlet of the submersible pump is connected to an inlet pipe 71 and a water extraction pipe 72 via a tee. The inlet of the water extraction pipe 72 is equipped with an anti-blocking screen. A retractable filter screen 8 is slidably mounted on the bottom of the housing 1. Valves (not shown) are installed at the ends of the two tees. These valves enable the submersible pump to pump water from below the partition 6 to above it or to the water bladder 7, or to pump water from the water bladder 7 to above the partition 6. Bottle labels or tags follow the water flow through the diverter trough, concentrating them below the partition 6. When it is necessary to clean the bottle labels or the labels, the submersible pump starts working, pumping water through the water suction pipe 72 and pumping the water into the water bag 7 through the bag outlet pipe 73. As the water enters, the water bag 7 gradually expands, and 95% of the water in the box body 1 is infused into the water bag 7. Then the submersible pump stops working, and the operator removes the filter screen 8 from the box body 1 and gradually extracts it. During the extraction process, the remaining water mixed with some bottle labels or the labels flows out of the box body 1, and most of the bottle labels or the labels are retained on the filter screen 8. The filter screen 8 is then cleaned. After the filter screen 8 is cleaned, it is pushed back into the box body 1 and fixed with bolts.

[0024] The housing 1 is provided with a toggle lever 3, located below the guide plate 9 and in front of the diverter plate 12. A stirring mechanism (not shown) is also provided in front of the guide plate 9. The stirring mechanism comprises a turntable, a toggle lever mounted on the turntable, and a drive motor that rotates the turntable. The drive motor is mounted outside the housing 1, while the turntable and toggle lever are located inside the housing 1. When washing bottles, the toggle lever, driven by the turntable, stirs the bottles, washing away impurities on their outer surfaces.

[0025] The toggle rod 3 is used to reduce the flow space of the packaging bottle and reduce the probability of the packaging bottle entering between the two washing boards 11 in a vertical state. Through the obstruction of the toggle rod 3, the packaging bottle flows between the two washing boards 11 in a horizontal state.

[0026] Inside the box 1, a screen plate 10 is mounted on one side of the discharge port via a shaft. One end of the shaft is connected to a motor. The screen plate 10 is provided with multiple mesh slots. A recessed plate seat 29 is provided at the end of the slots away from the shaft. A sleeve plate 28 is slidably mounted on the screen plate 10. A secondary slot is provided on the sleeve plate 28 at the position corresponding to the slots. A triangular set plate 30 is provided at the end of the secondary slot near the shaft. The set plate 30 is located in the slots. The sleeve plate 28 is sleeved on the screen plate 10 and is slidably connected to the screen plate 10 via the set plate 30. The motor drives the shaft to rotate, and the screen plate 10 rotates within the box 1. When the sleeve plate 28 is initially located below the horizontal plane of the shaft, under the action of its own weight, the sleeve plate 28 slides on the screen plate 10 and slides to the end away from the shaft. The sliding increases the operating area of ​​the entire screen plate 10, making it easier for the screen plate 10 to push the bottles with the bottle labels removed near the intercepting plate 13 out of the box 1. When the sleeve 28 is initially positioned above the horizontal plane of the axis, it slides toward the axis under its own weight, thereby reducing its length and facilitating the mesh plate 10 to drive the sleeve 28 to rotate within the housing 1. As the sleeve 28 slides on the mesh plate 10, the triangular plate 30 and the plate seat 29 clear any bottle or label clogs in the mesh slots and auxiliary slots.

[0027] The interior of the diverter plate 12 is hollow and is equipped with a small submersible pump and a water pressure sensor. The partition 6 is provided with multiple flow channels that connect to the internal space of the diverter plate 12. The small submersible pump is connected to the multiple flow channels via a multi-way pipe. The small submersible pump pumps water into the diverter plate 12 or pumps water under the partition 6. Retractable side bladders 15 are provided on both sides of the diverter plate 12. The side bladders 15 expand outward under the action of the water pressure inside the diverter plate 12 or contract under the action of the water pressure inside the housing 1. The side bladders 15 are distributed between the washboard 11 and the diverter plate 12. The washboard 11 is moved linearly by a reciprocating mechanism. The multi-way pipe diagram does not show the inlet and outlet connections of the small submersible pump. Valves are installed at the pipe openings of the multi-way pipe to cooperate with the operation of the small submersible pump, allowing the small submersible pump to pump water into the diverter plate 12 or extract water from the diverter plate 12 and send it to the bottom of the partition 6.

[0028] Four steps 4 are provided on the partition 6, one step 4 is located between the two washboards 11, the corners of the step 4 are rounded, the inside of the step 4 is hollow, one end of the step 4 is triangular, and a gate plate 22 is rotatably installed on the inside of the other end. A gate cylinder 27 is rotatably installed inside the step 4, and the cylinder rod of the gate cylinder 27 is rotatably connected to one end of the gate plate 22. A notch is provided in the middle of the other end of the gate plate 22, and a sensor for monitoring the packaging bottles is installed on the gate plate 22.

[0029] The reciprocating mechanism includes a bracket 18 symmetrically mounted on the end plate 16, and each bracket 18 is rotatably mounted with a telescopic rod 19 with retractable ends. A spring supporting telescopic reset is installed inside the telescopic rod 19, so that the two ends of the telescopic rod 19 are reset after telescoping. The two telescopic rods 19 are connected by a coupling shaft, and a connecting plate 17 is rotatably mounted between the telescopic ends of the two telescopic rods 19. Slide grooves are symmetrically provided on the end plate 16, and the connecting plate 17 is located in the slide groove. Slide blocks 24 are installed on both sides of the connecting plate 17, and a notch is provided on each of the two parallel end faces of the slider 24, and the two notches are in a perpendicular relationship. One notch is slidably connected to the connecting plate 17, and the other notch is slidably connected to the slide groove. One end of the connecting plate 17 is connected to the washboard 11; A crankshaft is provided between the two brackets 18 , and the crankshaft is rotatably connected to the coupling shaft through a shaft plate 25 . One end of the crankshaft is connected to a drive cylinder, which is a rotary hydraulic cylinder.

[0030] A plurality of files 20 are provided on the washboard 11, and spring grooves are provided on the narrow surfaces on both sides of the washboard 11. A "C"-shaped pressure frame 21 and a compression spring 23 are slidably installed in the spring groove. One end of the compression spring 23 rests on the pressure frame 21, and the other end rests on the cover plate that closes the spring groove.

[0031] The spring groove is composed of a cylindrical groove and a square groove. The length of the square groove is smaller than the length of the cylindrical groove, and the width of the square groove is smaller than the diameter of the cylindrical groove. The compression spring 23 is located in the cylindrical groove, and the cylindrical groove prevents the compression spring 23 from protruding outward after compression.

[0032] The pressure frame 21 consists of two telescopic plates and a roller rotatably mounted on the movable end of the telescopic plate. The telescopic plate consists of a fixed sleeve, a movable end (i.e., a movable plate) and a spring installed inside the fixed sleeve and connected to the movable end. A base (consisting of a disc and a square piece) is installed on one side of the fixed sleeve, and the base is located in the spring groove.

[0033] When the pressing frame 21 presses against the bottle, the two washboards 11 approach each other, and one end of the pressing frame 21 on each washboard 11 abuts against the other. As the washboards 11 approach, the pressing frame 21 begins to retract, allowing the file 20 on the washboard 11 to contact the bottle. When the file 20 is positioned exactly against the roller of the pressing frame 21, the pressure from the scraping grooves of the file 20 causes the roller to move upward along the grooves, clearing the required position for the file 20. When the file 20 and washboard 11 separate from the bottle, the retractable plate extends, and the pressing frame 21 resumes its pressure on the bottle.

[0034] When the power cylinder 2 drives the washboard 11 downward, the pressing frame 21 first contacts the outside of the bottle. After the washboard 11 is lowered to a certain height by the power cylinder 2, the pressing frame 21 presses the bottle onto the step 4, securing the bottle in position and facilitating subsequent labeling or bottle label removal. After the pressing frame 21 presses the bottle onto the step 4, as the washboard 11 moves downward, the pressing frame 21 moves in the spring groove and compresses the compression spring 23. When the washboard 11 is raised by the power cylinder 2, the pressing frame 21 remains pressed against the outside of the bottle under the action of the compression spring 23.

[0035] The washboard 11 is provided with a plurality of embedding grooves 26, which penetrate the washboard 11. The file 20 is slidably installed in the embedding groove 26 through a return spring. The length of the file 20 located in the embedding groove 26 is less than the thickness of the washboard 11. One end of the file 20 is provided with two arc-shaped scraping grooves of different diameters. The two scraping grooves are transitioned by an arc-shaped surface. The diameter of the scraping groove at the bottom is larger than the diameter of the scraping groove at the top. File teeth are provided in the scraping groove, and a blade inclined downward is provided on the arc-shaped surface.

[0036] A plurality of visual sensors (not shown) are also provided on the end plate 16. The visual sensors are used to detect the posture of the packaging bottle between the two side bags 15, so that the controller can control the driving cylinder according to the detection results of the visual sensors, so that there is a height difference between the two washboards 11, so that the washboard 11 in the lower position and the pressing frame 21 thereon first contact one side of the packaging bottle. As the washboard 11 and the pressing frame 21 descend, the posture of the packaging bottle is adjusted, so that the washboard 11 can remove the bottle label on the packaging bottle.

[0037] The working principle of the present invention is as follows: water or a mixture of water and chemical solvents for soaking packaging bottles is stored in the box 1. The packaging bottles are put into the box 1, and the stirring mechanism stirs and cleans the packaging bottles. The water flows out from the guide plate 5, carrying the packaging bottles to flow in the direction of the guide plate 9. Under the restriction of the guide plate 9 and the obstruction of the toggle rod 3, the packaging bottles flow in a horizontal state between the two side bags 15 and are intercepted by the gate plate 22.

[0038] After the bottle is intercepted between the two side bags 15, the power cylinder 2 drives the end plate 16 to descend a certain height, so that the two washboards 11 fall between the two diverter plates 12 and are located on the outside of the bottle. The bottles are pressed onto the step 4 by the pressure rack 21. Then the small submersible pump starts to work, extracting water from under the partition 6 and pumping it into the diverter plate 12. As the pressure in the diverter plate 12 increases, the side bags 15 extend outward under the action of the water pressure and gradually squeeze the washboard 11. The washboard 11 drives the connecting plate 17 to move horizontally in the chute, causing the two telescopic ends of the telescopic rod 19 to contract, so that the washboard 11 fits the surface of the bottle, and also makes the file 20 contact or fit with the bottle. When the water pressure detected by the water pressure sensor reaches the set value, the small submersible pump stops working, and then the power cylinder 2 works again and pushes the washboard 11 downwards, so that the file 20 scrapes the bottle sticker or label off the outside of the bottle. The power cylinder 2 drives the washboard 11 After descending to a certain height (the descending height is set in the controller), the small submersible pump pumps the water in the diverter plate 12 to the bottom of the partition 6, causing the side bags 15 to contract under the action of the water pressure in the box body 1, and the washboard 11 to return to its original position and separate from the bottle under the action of the spring in the telescopic rod 19. After the washboard 11 and the file 20 are separated from the bottle, the power cylinder 2 brings the washboard 11 back to the height before the descent, and then the small submersible pump again pumps the water under the partition 6 into the diverter plate 12, causing the side bags 15 to expand and squeeze the washboard 11 again, so that the washboard 11 is in contact with the outer surface of the bottle again. After multiple scraping actions, the bottle stickers or labels on the outer surface of the bottle are cleaned.

[0039] After cleaning, the side bag 15 shrinks under the action of water pressure, the washboard 11 is reset under the drive of the power cylinder 2, and the cylinder rod of the gate cylinder 27 is retracted, so that the gate plate 22 is gradually tilted under the drive of the gate cylinder 27 until the bottle passes over the gate plate 22 under the carry of the water flow. After the sensor detects that the bottle passes over the gate plate 22, the gate cylinder 27 pushes the gate plate 22 back to the vertical state again to intercept the next bottle.

[0040] Driven by the water flow, the bottle passes over the gate plate 22 and flows to the position of the interception plate 13. The bottle label or label follows the water flow through the interception plate 13, while the bottle is retained above the interception plate 13. The bottle is removed from the box body 1 by the rotation of the mesh plate 10 and the sliding extension of the sleeve plate 28.

[0041] When the bottle is located between the two side bags 15, the visual sensor detects that the bottle is a square plastic bottle with the wide side (i.e., the side with the label or the opposite side with the label) facing upwards, the controller controls the drive cylinder to work, so that the crankshaft drives one end of the telescopic rod 19 to descend through the shaft plate 25, so that there is a height difference between the two washboards 11, and then the power cylinder 2 brings the washboard 11 down. The washboard 11 in the lower position and the pressing frame 21 on it first contact one side of the bottle. As the power cylinder 2 continues to descend, the bottle is flipped over a certain angle, and then the power cylinder 2 brings the washboard 11 back to its original position, preparing for the subsequent washboard 11 to be outside the bottle and the pressing frame 21 to press the bottle on the step 4. When the pressing frame 21 presses the bottle, it will press on the narrow side of the bottle.

[0042] When cleaning square plastic bottles, the pressing frame 21 is pressed on the narrow surface, and the rubbing board 11 is driven by the power cylinder 2 to scrape the bottle label or label once. Then, the driving cylinder can be selected to drive the two rubbing boards 11 to move up and down toward each other to rub off the bottle label or label on the outer surface of the packaging bottle. Alternatively, the rubbing board 11 and the file 20 can be separated from the packaging bottle, and then attached to the outer surface of the packaging bottle again, and then lowered again to scrape off the bottle label or label.

[0043] When the bottle is a mineral water bottle, rubbing is not used to remove the bottle label or label. The drive cylinder uses the crankshaft to horizontally position the telescopic rod 19, placing the two telescopic ends of the telescopic rod 19 at the same height, allowing the power cylinder 2 to drive the two washboards 11 to scrape the bottle label or label from the bottle surface. When the side bag 15 is extended and retracted, part of the side bag 15 squeezes into the embedded groove 26, pushing the file 20 out of the embedded groove 26. When removing the bottle label or label from the outer surface of the mineral water bottle, because the scraping groove is closely attached to the outer surface of the bottle, when the washboard 11 descends, the file 20 can smoothly follow the curve of the mineral water bottle and tear or scrape the bottle label or label from the outer surface of the mineral water bottle.

[0044] When cleaning both square plastic bottles and mineral water bottles, the blade of the file 20 is pressed against the outer surface of the square plastic bottle and the scraping groove is attached to the outer surface of the mineral water bottle by the side bag 15. Driven by the power cylinder 2, the washboard 11 drives the file 20 downward, and the blade and scraping groove of the file 20 scrape off the bottle stickers or labels on the outer surface of the packaging bottle.

[0045] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above and that the invention can be embodied in other specific forms without departing from the spirit or essential characteristics of the invention.
