They have the characteristics of not being easy to break, low cost, high transparency, food-grade raw materials, etc.
[0003] However, plastic bottles take hundreds of years to degrade, and microplastics and harmful substances generated during the degradation of plastic bottles can enter the soil and water, polluting the environment. Therefore, in order to reduce pollution to the environment, plastic bottles need to be recycled. Plastic bottles are mainly made of PET, and PET raw materials rely on oil. Recycling plastic bottles to make new plastic bottles can reduce the consumption of oil resources, and recycled plastic bottles can not only be used to produce new plastic bottles, but also be regenerated into fibers to make fiber clothing, such as each single shoulder bag consumes about 6.9 bottles, furniture, building materials, etc. Create economic value and reduce landfill.
[0004] However, the caps, labels and bodies of the plastic bottles are currently made of different materials. When recycling plastic bottles, if the caps and labels are removed, the bottle body is recycled separately, which can improve the purity of plastic bottle recycling. However, the recycling of the label can be handled by a label removal machine, and the cap is usually crushed together with the bottle body, and after screening and cleaning, the bottle body fragments that need to be recycled can be selected, which prolongs the plastic bottle recycling process and reduces the plastic bottle recycling efficiency. SUMMARY
[0005] The application discloses a plastic bottle recycling device, which aims to solve the technical problems of the prior art that the cap is not removed at the same time as the label, prolonging the plastic bottle recycling process and reducing the plastic bottle recycling efficiency.
[0006] To solve the above technical problems, the technical scheme adopted by the application is as follows:
[0007] The utility model provides a plastic bottle recycling device, including the body, be equipped with the delivery port on the body, the conveying device, the bottle cap label removal device, the smashing device and the collection device are equipped in the body along the direction of being close to the delivery port to the direction of being far from the delivery port in proper order, the bottle cap label removal device includes the bottle cap removal part and the label removal part, the bottle cap label removal device includes the first clamping device and the second clamping device can be clamped to the bottle cap and the bottle respectively, the first clamping device is driven through the first drive device, the first drive device is connected with the label removal part through the gear set, the label removal part can move along the axial direction of bottle through the gear set, and the label is cut.
[0008] After adopting the technical scheme, the bottle cap label removal device is arranged between the conveying device and the smashing device, the bottle cap and the bottle are clamped by the first clamping device and the second clamping device respectively, the first clamping device is rotatable through the first drive device, the bottle cap is rotatable through the first drive device, the connection between the bottle cap and the bottle is disconnected, and the bottle cap is removed from the bottle.
[0009] The device can remove the bottle cap and the label from the bottle simultaneously through the first drive part, recycle the bottle cap, the label and the bottle body respectively, improve the cleanliness of plastic bottle recycling, and improve the economic benefit of plastic bottle recycling.
[0010] The label removal part includes a first screw rod connected with the gear set, a first sliding block connected with the first screw rod, a rolling cutter set provided on the first sliding block, a cutter shaft rotationally connected with the first sliding block, a plurality of curved first cutter teeth provided on the cutter shaft, the first cutter teeth being curved towards the direction of the first sliding block, and a second drive device driving the rolling cutter set.
[0011] After adopting the technical scheme, the first sliding block is driven to slide on the first screw rod through the rotation of the first screw rod, and the rolling cutter set is driven to rotate through the second drive device, so that the first cutter teeth contact the label on the bottle and cut the label on the bottle, thereby removing the label from the bottle. The first screw rod and the first sliding block increase the stability of the rolling cutter set in cutting the label, thereby improving the stability of the device in use.
[0012] The first cutter teeth are curved, which can better hook the label and cut and crush the label, thereby improving the crushing efficiency and effect of the label.
[0013] The first clamping device comprises two oppositely arranged first clamping plates, the two first clamping plates are connected through a bottom plate, and the two first clamping plates are rotationally connected with the bottom plate, the end of each first clamping plate is provided with a hooking knife matched with the gasket of the bottle cap, the hooking knife is rotationally connected with the first clamping plate, the bottom plate is provided with a third driving device capable of adjusting the angle of the first clamping plate relative to the bottom plate, and the opposite side of the two clamping plates is provided with a non-slip pad.
[0014] After the technical scheme is adopted, the first clamping device comprises a bottom plate and a first clamping plate arranged opposite to the bottom plate, the bottom plate is rotationally connected with the first clamping plate, the third driving device can drive the two first clamping plates to rotate towards each other to clamp the bottle cap, and the non-slip pad increases the stability of the first clamping device in clamping the bottle cap, thereby improving the stability of the device during use. At the same time, this arrangement can cooperate with any size of bottle cap to clamp the bottle cap, thereby improving the practicality of the device.
[0015] In addition, the hooking knife is arranged at the bottom of the first clamping plate and rotationally connected therewith, this arrangement enables the hooking knife to be in close contact with the bottle body of the plastic bottle during the rotation of the first clamping plate for clamping the bottle cap, and gradually contacts the gasket ring of the bottle cap during the process of removing the bottle cap from the bottle body, and the gasket ring can be hooked by the hooking knife to remove the gasket ring from the plastic bottle, thereby further improving the cleanliness of the plastic bottle recycling.
[0016] The first driving device comprises a first rotary motor, the gear set comprises a first gear sleeved on the first rotary motor, the first gear is engaged with a second gear, and the second gear is connected with a first lead screw through a first one-way bearing.
[0017] After the technical scheme is adopted, the first gear is arranged on the first rotary motor, the first gear is engaged with the second gear, and the first one-way bearing is arranged between the second gears, this arrangement enables the first one-way bearing to be locked during the removal of the bottle cap, drives the first lead screw to rotate, and drives the label removal part to move in the axial direction of the plastic bottle, thereby removing the label during the removal of the bottle cap and improving the recycling efficiency of the plastic bottle.
[0018] The arrangement of the first gear and the second gear increases the stability of the device during use, thereby improving the stability of the device.
[0019] The second clamping device comprises an insertion rod capable of being inserted into the plastic bottle, the insertion rod is provided with an abutting device capable of abutting against the bottom of the plastic bottle, the second clamping device is driven by a fourth driving device, and the fourth driving device is provided with a reset device capable of resetting the label removal part.
[0020] After adopting this technical solution, the second clamping device is fixed to the bottle body through the insertion rod and the adsorption device. The second clamping device is driven by the fourth driving device. The first driving device and the fourth driving device can be set to different speeds, so that both the bottle cap and the bottle body can rotate. However, because the speeds of the bottle cap and the bottle body are different, the label removal effect can be further improved by rotating the bottle body and the rolling blade assembly, and the purity of plastic bottle recycling can be further improved, provided that the bottle cap is removed.
[0021] The fourth drive unit is equipped with a reset device that resets the label removal section, which allows the label removal section to return to its initial position, facilitating the removal of labels and caps from the next plastic bottle and improving the convenience of using the device.
[0022] The fourth driving device includes a third rotary motor, and the reset device includes a third gear mounted on the third rotary motor. The third gear meshes with a fourth gear, and the fourth gear is connected to a second lead screw. The second lead screw is connected to a second slider, and the second slider is connected to the main body. The second lead screw can be inserted into a first lead screw to drive the first lead screw to rotate. The second lead screw is connected to the first lead screw through a second one-way bearing.
[0023] By adopting this technical solution, the first lead screw, in conjunction with the second lead screw, allows the first lead screw to slide the first slider towards the first clamping device to remove the label during the bottle cap removal step. Simultaneously, the second lead screw moves within the second slider, allowing it, along with the second one-way bearing, to insert into the first lead screw. However, due to the presence of the second one-way bearing, the first lead screw does not rotate synchronously with the second lead screw at this time. Only when the second drive device rotates in the reverse direction can the second one-way bearing be locked, causing the first lead screw to rotate in the reverse direction and the first slider to move away from the first clamping device, thus resetting the label removal section. This facilitates the removal of labels and caps from the next plastic bottle, making it more convenient to use.
[0024] The rolling cutter tooth assembly is further provided with a second cutter tooth, which is rotatably connected to the first cutter tooth, and the bending direction of the second cutter tooth is opposite to that of the first cutter tooth. The first cutter tooth and the second cutter tooth are connected by a hinge rod. The first cutter tooth is provided with a limiting ring that cooperates with the second cutter tooth. The second cutter tooth is disposed inside the limiting ring. The first cutter tooth is also provided with a first receiving groove for accommodating the second cutter tooth. A return spring is also provided between the first cutter tooth and the second cutter tooth. The second cutter tooth can cut through plastic bottles.
[0025] With this technical solution, a second blade is provided on the rolling blade assembly. During the stroke of removing the bottle cap and label, the second blade is tangential to the bottle body. During the resetting process of the label removal section, the second blade cuts the bottle body. The cut bottle body can more easily enter the gaps between the crushing rollers and be crushed during the crushing process. Therefore, the second blade provides initial cutting of the plastic bottle, improving the crushing rate.
[0026] The hinge, return spring, and limit ring increase the stability of the second cutter tooth during use, thereby improving the stability of the device during use.
[0027] The label removal unit is further provided with an adhesive removal device, which includes a bracket set on the first slider. The bracket is provided with a ring frame that cooperates with the plastic bottle. The ring frame is provided with a first sponge that absorbs adhesive cleaning agent and a second sponge that absorbs adhesive cleaning agent. The first sponge and the second sponge are arranged adjacent to each other through a partition.
[0028] With this technical solution, the first sponge absorbs adhesive cleaning agent and simultaneously contacts the bottle body during the cap and label removal process, removing the adhesive adhering to the bottle. During the label removal process, the second sponge absorbs and cleans the adhesive cleaning agent adhering to the bottle body, ensuring the cleanliness of the bottle's outer surface. This reduces the number of subsequent bottle-crushing cleaning operations and saves water. The partition further ensures the cleanliness of both the first and second sponges during use, improving the cleaning effect on the bottle.
[0029] The conveying device includes a first conveyor belt and a second conveyor belt that is stepped with the first conveyor belt. The first conveyor belt is positioned above the second conveyor belt. A gap is provided between the first conveyor belt and the second conveyor belt. The bottle cap label removal device is positioned between the gap. An inclined plate is provided on the second conveyor belt. The inclined plate slopes downward along the first conveyor belt toward the second conveyor belt.
[0030] By adopting this technical solution, the first and second conveyor belts are configured as a stepped structure, and the bottle cap and label removal device is placed between the first and second conveyor belts. After the bottle cap and label are removed, the bottle can be transported to the second conveyor belt via an inclined plate and enter the crushing device. This improves the ease of use of the device. This configuration does not interfere with the rotation or other movements of the first and second clamping devices, ensuring the normal operation of the device.
[0031] The first conveyor belt and the second conveyor belt are provided with a debris collection device. The debris collection device includes a fan and a collection bag connected to the gap. The air outlet of the fan is set towards the gap between the first conveyor belt and the second conveyor belt. The fan is set above the bottle cap label removal device. The collection bag is set below the gap. The second conveyor belt is also provided with a heating device that can heat the second conveyor belt.
[0032] With this technical solution, a fragment collection device is installed between the first and second conveyor belts. When the rolling blades cut the label, a fan sucks up the cut label fragments and collects them in a collection bag, preventing them from entering the second conveyor belt and being crushed along with the bottle during the crushing process, thus ensuring the purity of the recycled bottle. The heating device works during the return stroke of the label removal section. The second blades cut open the bottle, allowing moisture to flow out and reducing the water content. When the bottle enters the second conveyor belt, the heating device dries it, further reducing the water content. The heat also helps reduce the bottle's volume, facilitating crushing. For bottles containing purified water or other clean materials, the dried bottles are directly crushed by the crushing device, and the resulting shredded material can be directly used for reprocessing at other manufacturers without separate cleaning, thus saving resources.
[0033] In summary, due to the adoption of the above technical solution, the beneficial effects of the present invention are:
[0034] (1) This device can remove the bottle cap and label from the bottle body simultaneously through the first drive unit, and recycle the bottle cap, label and bottle body separately, which can improve the cleanliness of plastic bottle recycling and improve the economic benefits of plastic bottle recycling. At the same time, there is no need to screen the bottle cap and label in the subsequent process, which shortens the process flow line and can improve the recycling efficiency of plastic bottles.
[0035] (2) The screw and the first slider increase the stability of the rolling cutter group in cutting the label, thereby improving the stability of the device during use. The first cutter is set with a curved structure, which can better hook the label and cut and crush it, improving the crushing efficiency and crushing effect.
[0036] (3) The device is equipped with a third drive unit, a first clamping plate, an anti-slip pad, and a hook, which can remove the gasket ring while removing the bottle cap, ensuring the purity of the recycled plastic bottle. At the same time, it can clamp bottle caps of any size, improving the practicality of the device.
[0037] (4) The second drive device is equipped with a reset device to reset the label removal part, which can return the label removal part to the initial position, making it easier to remove the label and cap of the next plastic bottle, thus improving the convenience of the device when in use.
[0038] (5) A second blade is provided on the rolling blade assembly. During the stroke of removing the bottle cap and label, the second blade is tangential to the bottle body. During the resetting process of the label removal part, the second blade cuts the bottle body. The cut bottle body can more easily enter the gap between the crushing wheels and be crushed during the crushing process. Therefore, the setting of the second blade performs preliminary cutting of the plastic bottle and improves the crushing rate of the plastic bottle.
[0039] (6) Setting up a first sponge and a second sponge can remove the adhesive on the bottle body, further improving the purity of the recycled plastic bottle and making it more economically valuable. Attached Figure Description

The central control device can control the rotation direction of the first rotary motor 301, the second rotary motor 401, and the third rotary motor 501, the extension and retraction of the electric telescopic rod 305, and the distance sensed by the distance sensor 104. The distance sensed by the distance sensor 104 controls the electric telescopic rod 305 to clamp the bottle cap, while simultaneously allowing the insertion rod 503 to be inserted into the bottle.
[0101] In this embodiment, the conveying device includes a first conveyor belt 2 and a second conveyor belt 7 arranged in a step with the first conveyor belt 2. The first conveyor belt 2 is arranged above the second conveyor belt 7. A gap is provided between the first conveyor belt 2 and the second conveyor belt 7. The bottle cap label removal device is arranged between the gap. An inclined plate 701 is provided on the second conveyor belt 7. The inclined plate 701 is inclined downward along the first conveyor belt 2 toward the second conveyor belt 7.
[0102] In this embodiment, the first conveyor belt 2 is provided with several guide bars 201, which are evenly arranged on the first conveyor belt 2, and the distance between two adjacent guide bars 201 is 5cm.
[0103] In this embodiment, the main body 1 is provided with a guide plate 103 connected to the dispensing port 102. The guide plate 103 is inclined, with one end connected to the dispensing port 102 and the other end connected to the first conveyor belt 2. When the user puts the plastic bottle into the main body 1 through the dispensing port 102, the plastic bottle can enter the first conveyor belt 2 along the guide plate 103. Under the action of the guide strips 201 on the first conveyor belt 2, it is guided in a parallel manner to the guide strips 201, and then clamped by the first clamping device and the second clamping device.
[0104] In this embodiment, the gap between the first conveyor belt 2 and the second conveyor belt 7 is set to 3cm, and the first conveyor belt 2 and the second conveyor belt 7 are inclined toward the gap.
[0105] In this embodiment, the inclination angle of the inclined plate 701 is 30 degrees.
[0106] In this embodiment, a debris collection device is also provided between the first conveyor belt 2 and the second conveyor belt 7. The debris collection device includes a fan 8 and a collection bag 6 connected to the gap. The air outlet of the fan 8 is arranged facing the gap between the first conveyor belt 2 and the second conveyor belt 7, and the fan 8 is arranged above the bottle cap label removal device. The collection bag 6 is arranged below the gap. A heating device is also provided on the second conveyor belt 7, which can heat the second conveyor belt 7.
[0107] In this embodiment, the fan 8 is connected to the top wall of the body 1 via a support base.
[0108] In this embodiment, the first lead screw 310 and the second lead screw 507 pass through the collection bag 6 and are placed inside the collection bag 6. The collection bag 6 is suspended below the gap.
[0109] In this embodiment, the side wall of the main body 1 is provided with a hook for hanging the collection bag 6. After connecting the collection bag 6 to the hook, it can be hung below the gap.
[0110] In this embodiment, the collection bag 6 is provided with an adhesive part made of Velcro, through which a through groove that cooperates with the first lead screw 310 and the second lead screw 507 can be formed on the collection bag 6.
[0111] In this embodiment, the heating device is an electric heating wire, which is also connected to the main control device.
[0112] The specific method of using this invention is as follows:
[0113] Reference Figures 1-7 When using this device, the user first enters their personal account via facial recognition, then scans the QR code on the plastic bottle against the scanning interface to accumulate points. Upon receiving the scanned information, the central control device automatically starts the first conveyor belt 2, the second conveyor belt 7, and the distance sensor 104. The user then places the plastic bottle into the inlet 102, where it enters the first conveyor belt 2 and, under the guidance of the guide bar 201, becomes parallel to the conveyor belt. Simultaneously, the distance sensor 104 measures the relative position of the plastic bottle on the first conveyor belt 2 and the first clamping plate 304. When the distance becomes zero, the distance sensor 104 transmits this information to the central control device. The central control device then drives the third drive device to extend and retract, clamping the bottle cap, inserting the drive rod 503 into the bottle body, and making the fixing plate 504 contact the bottom of the bottle body to fix it. Finally, the first rotary motor 301 and the third rotary motor 501 are driven separately to make the bottle cap and bottle body rotate at different speeds, thus removing the bottle cap from the bottle body.
[0114] While removing the bottle cap, the first gear 302 and the second gear 309 mesh to drive the first lead screw 310 to rotate. The first slider 311 on the first lead screw 310 slides towards the gear set. At the same time, the second rotary motor 401 drives the cutter shaft to rotate, causing the first cutter teeth 402 to cut the label. Simultaneously, the second lead screw 507 rotates inside the second slider 506, but due to the presence of the second one-way bearing, it does not drive the first lead screw 310 to rotate; it only slides within the receiving cavity inside the first lead screw 310 until the label is cut. Because the fan 8 is located above the gap, it can blow the label into the gap, and the label fragments are collected by the collection belt.
[0115] After the label is removed, the main control device drives the third drive gear to rotate in the reverse direction, and the second lead screw 507 rotates in the first lead screw 310 in the reverse direction. At this time, the second one-way bearing is locked, the first one-way bearing 313 is disconnected, and the first lead screw 310 rotates in the reverse direction, driving the first slider 311 to slide in the reverse direction and return to the initial position, which is convenient for the next label removal. At the same time, the drive rod 503 is moved out of the bottle body, and the bottle body enters the second conveyor belt 7 under the action of the inclined plate 701 and is transported to the crushing device for crushing, and then collected by the collecting device.
[0116] This device, through its first drive unit, can simultaneously remove bottle caps and labels from the bottle body, recycling the caps, labels, and bottle body separately. This improves the cleanliness of recycled plastic bottles and increases their economic efficiency. Furthermore, it eliminates the need for subsequent screening of caps and labels, shortening the process flow and further enhancing recycling efficiency.
