Description

Technical Field

[0001] This utility model relates to the field of classification and recycling technology, and mainly relates to a bottle recycling device. Background Technology

[0002] With the total amount of urban waste increasing year by year, waste disposal has become one of the important factors affecting urban development. In order to improve waste disposal capacity, it is necessary to do a good job of sorting household waste at the time of disposal. Beverage bottles are a major recyclable item, and beverage bottle recycling devices can sort and recycle them.

[0003] Because beverage bottles are made of various materials and have different recycling values, they are currently mainly made of metal, plastic and glass. The value and performance of these three materials differ greatly, which directly affects the subsequent processing technology and the value of reuse.

[0004] Currently, automated beverage bottle recycling devices mainly use different sensors installed on conveyor belts to identify and differentiate the materials of the bottles, thereby sorting and classifying them for recycling. However, because the identification and sorting process only begins once the bottles enter the conveyor belt, the process is time-consuming and inefficient. Utility Model Content

[0005] The purpose of this invention is to provide a bottle recycling device that can identify and classify beverage bottles before they enter the conveyor belt, thereby effectively improving the recycling efficiency of the bottle recycling device.

[0006] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0007] One aspect of this application provides a bottle recycling device, including a housing forming the outer shell of the recycling device; a bottle feeding assembly disposed on the housing, the bottle feeding assembly including a feeding cylinder, one end of the feeding cylinder being exposed outside the outer wall of the housing, and the other end of the feeding cylinder extending into the interior of the housing, the feeding cylinder having an annular structure, the annular inner surface of the feeding cylinder forming a feeding channel, and an inlet provided at the end exposed outside the housing for receiving bottles; a first sensor disposed on the feeding cylinder, the first sensor being used to sense bottles made of metal and generate a first detection signal; a second sensor disposed on the feeding cylinder, the second sensor being used to sense bottles made of non-metallic material and generate a second detection signal; and a conveying mechanism disposed inside the housing, the conveying mechanism including a first... A drive unit is disposed inside the housing; a conveyor belt, the input end of which is located at the end of the feeding channel away from the inlet; the first drive unit is drively connected to the conveyor belt and is used to drive the conveyor belt to move; the conveyor belt is provided with a first position and a second position at intervals along its conveying direction; a controller is connected to the first sensor, the second sensor, and the first drive unit respectively; the controller is configured to: control the first drive unit to stop according to the first detection signal generated by the first sensor, so that the bottle on the conveyor belt stops at the first position; and control the first drive unit to stop according to the second detection signal generated by the second sensor, so that the bottle on the conveyor belt stops at the second position.

[0008] The above technical solution has the following advantages or beneficial effects: A first sensor and a second sensor are respectively installed on the feeding cylinder. During the process of the bottle passing through the feeding channel, the first and second sensors can identify whether the bottle material is metal or non-metal and send detection signals to the controller in real time. Thus, the identification action of the bottle recycling device is synchronized with the bottle feeding process, eliminating the need to wait for the bottle to enter the conveyor belt before starting. When the bottle reaches the input end of the conveyor belt, the controller has already obtained its material information, which helps to shorten the overall processing time of a single bottle from input to sorting completion. Furthermore, the conveyor belt is pre-set with a first position corresponding to metal bottles and a second position corresponding to non-metal bottles. The controller obtains the first and second detection signals based on the bottle feeding stage of the feeding component, and then controls the first drive component to stop at the corresponding position. For example, when a metal bottle passes through the feeding cylinder, the first sensor triggers the first detection signal, and the controller plans the conveyor belt running distance in advance, stopping immediately when the bottle is sent to the first position by the conveyor belt; for non-metal bottles, the second sensor triggers the signal, and the controller controls it to stop at the second position. During this process, the conveyor belt transports the identified bottles to a preset position, thus solving the problem that traditional bottle recycling devices only detect and classify bottles when they begin to be transported. This reduces the ineffective operating time of the conveyor structure, allowing more bottles to be processed per unit time and significantly improving classification efficiency.

[0009] In some embodiments of this application, a bottle recycling device is provided. The conveying mechanism includes a first position sensor, which is configured to correspond to a first position of the conveyor belt. When the bottle moves to the first position, the first position sensor generates a first control signal. A controller is connected to the first position sensor. When the controller senses the first detection signal generated by the first sensor and the first position sensor generates the first control signal, the controller controls the first drive component to stop.

[0010] Another technical solution in the above-mentioned technical solution has the following advantages or beneficial effects: the first detection signal sensed by the first sensor serves as the trigger condition for controlling the first drive component to stop, while the first control signal sensed by the first position sensor when the bottle reaches the first position serves as the execution condition. The bottle recycling device initially identifies the material of the bottle at the bottle feeding component, determines the position of the bottle through the first position sensor, and finally executes the stop, making the controller's control of the conveyor belt more consistent with the actual operating state, and improving the stability and anti-interference ability of the bottle recycling device during continuous operation.

[0011] In some embodiments of this application, a bottle recycling device is provided, wherein the controller is connected to the second position sensor, and the second position sensor is configured to correspond to the second position of the conveyor belt, so that when the bottle moves to the second position, the second position sensor can generate a second control signal; the controller is connected to the second position sensor, and when the controller senses the second detection signal generated by the second sensor and the second position sensor generates the second control signal, the controller controls the first drive unit to stop.

[0012] Another technical solution in the above-mentioned technical solution has the following advantages or beneficial effects: the second detection signal sensed by the second sensor serves as the trigger condition for controlling the first drive component to stop, while the second control signal sensed by the second position sensor when the bottle reaches the second position serves as the execution condition. The bottle recycling device initially identifies the material of the bottle at the bottle feeding component, determines the position of the bottle through the first position sensor, and finally executes the stop, making the controller's control of the conveyor belt more consistent with the actual operating state, and improving the stability and anti-interference ability of the bottle recycling device during continuous operation.

[0013] In some embodiments of this application, a bottle recycling device is provided. A third sensor is provided on the conveyor belt, corresponding to a second position on the conveyor belt. The third sensor is used to detect the weight of the bottles on the conveyor belt. When the third sensor detects that the weight of the bottles on the conveyor belt is greater than a preset threshold, the third sensor generates a third control signal. The conveying mechanism also includes a sorting arm with a sorting channel arranged at an angle downwards. The lower end of the sorting arm is rotatably connected to the interior of the housing. A second driving member is driven to the sorting arm and is used to drive the sorting arm to rotate. A controller is connected to both the second driving member and the third sensor. The controller can control the second driving member to operate according to the third control signal, driving the sorting arm to rotate so that the upper end of the sorting channel is connected to the end of the conveyor belt away from the inlet, or keeps the upper end of the sorting channel connected to the end of the conveyor belt away from the inlet.

[0014] Another technical solution described above has the following advantages or beneficial effects: When the third sensor detects that the weight of the bottle on the conveyor belt exceeds a preset threshold, and the bottle is made of heavy non-metallic glass, such as a glass bottle, the controller can generate a third control signal based on the third sensor, thereby triggering the second drive unit to move the sorting arm, connecting the upper end of the sorting channel with the end of the conveyor belt away from the inlet. At this time, the first drive unit drives the conveyor belt to move, thereby transferring the glass bottle into the sorting channel, and then moving it to other collection locations through the sorting channel.

[0015] In some embodiments of this application, a bottle recycling device is provided, the bottle recycling device further comprising a second recycling bin located below the end of the conveyor belt away from the inlet, the second recycling bin having a second opening at its top; when the third sensor detects that the weight of the bottles on the conveyor belt is less than a preset threshold, the third sensor can generate a fourth control signal; the controller can control the second drive unit to operate according to the fourth control signal, driving the sorting arm to rotate, so that the upper end of the sorting channel is separated from the end of the conveyor belt away from the inlet, or keeping the upper end of the sorting channel separated from the end of the conveyor belt away from the inlet.

[0016] Another technical solution described above has the following advantages or beneficial effects: When the third sensor detects that the weight of the bottle on the conveyor belt is less than a preset threshold, and the bottle is made of lightweight non-metallic glass material, such as a plastic bottle, the controller can generate a third control signal based on the third sensor, thereby triggering the second drive unit to move and causing the upper end of the sorting channel to separate from the end of the conveyor belt away from the inlet. The first drive unit drives the conveyor belt to move, at which point the plastic bottle falls directly from the end of the conveyor belt and enters the second recycling bin through the second opening.

[0017] In some embodiments of this application, a bottle recycling device is provided. The conveying mechanism includes a guide member disposed below the end of the conveyor belt away from the inlet. The guide member has a guide groove that is arranged at an angle downwards, and the lower end of the guide groove is located above the second opening.

[0018] Another technical solution described above has the following advantages or beneficial effects: Due to the irregular shape and light weight of plastic bottles, they are easily affected by air resistance and may shift position when falling. The inertia of the conveyor belt may also cause the bottle to be thrown slightly off-center, deviating from the second opening. In this embodiment, by installing the guide below the end of the conveyor belt away from the inlet, the guide groove forms a constrained, fixed channel. After falling, the bottle is restricted to sliding within the groove, allowing it to fall precisely into the opening of the second recycling bin along the guide groove. This helps to avoid the problem of the bottle shifting off-center from the second recycling bin during its descent.

[0019] In some embodiments of this application, a bottle recycling device is provided, the bottle recycling device further comprising a third recycling bin, the top of the third recycling bin having a third opening; the conveying mechanism includes a second slide rail, the second slide rail being arranged inclined downwards, the upper end of the second slide rail being connected to the lower end of the sorting arm, and the lower end of the second slide rail being located above the third opening; when the upper end of the sorting channel is connected to the end of the conveyor belt away from the input port, the bottles on the conveyor belt can enter the second slide rail through the sorting channel and enter the third recycling bin through the third opening.

[0020] Another technical solution described above has the following advantages or beneficial effects: the second slide rail is arranged at an angle downwards. The upper end of the second slide rail is connected to the lower end of the sorting arm, thereby connecting to the outlet of the sorting channel. The lower end of the second slide rail extends above the third opening of the third recycling bin, forming a continuous conveying path from the sorting arm to the third recycling bin. Specifically, when the third sensor detects that the weight of the bottle exceeds a preset threshold, the upper end of the sorting arm connects to the end of the conveyor belt, and the conveyor belt delivers the bottle to its end, allowing it to enter the sorting channel of the sorting arm. The bottle slides down the inclined sorting channel to the second slide rail, and then slides into the third recycling bin via the inclined second slide rail, completing the recycling of the heavy glass bottle. The inclined arrangement utilizes gravity to assist the bottle's sliding, eliminating the need for additional power to complete the conveying process and further simplifying the transmission structure of the bottle recycling device.

[0021] In some embodiments of this application, a bottle recycling device is provided. The bottle recycling device includes a guide plate movably disposed within a third recycling bin. The top wall of the guide plate and the side wall of the third recycling bin enclose a receiving space for accommodating the bottle. A lifting and moving assembly is disposed within the third recycling bin and is tractively connected to the guide plate for driving the guide plate to perform lifting and moving motion. The top wall of the guide plate is inclined relative to the horizontal plane, and the upper end of the guide plate is arranged below the end of the second slide rail away from the sorting arm.

[0022] Another technical solution described above has the following advantages or beneficial effects: Because the top wall of the guide plate is inclined relative to the horizontal plane, the bottles are prevented from falling vertically. Instead, the bottles slide naturally down the inclined surface of the guide plate under gravity, significantly reducing the impact during the fall. For fragile glass bottles or bottles made of other materials, this effectively prevents breakage or other damage during transport to the recycling bin. Furthermore, the guide plate and the side wall of the third recycling bin form a storage space for the fallen glass bottles. The lifting and moving component is connected to the guide plate and can drive the guide plate to move up and down along the height of the third recycling bin. When there are few bottles in the storage space, the lifting and moving component drives the guide plate upwards, bringing it closer to the opening of the third recycling bin. At this time, the drop height of the bottle from the lower end of the second slide rail to the guide plate is minimal, further reducing impact. As the number of bottles gradually increases and the storage space is occupied, the lifting and moving component drives the guide plate downwards, increasing the volume of the storage space while maintaining a low drop height of the bottle from the lower end of the second slide rail to the guide plate.

[0023] In some embodiments of this application, a bottle recycling device is provided, comprising a first recycling bin disposed within a housing, the first recycling bin being located below a first position of a conveyor belt, the top of the first recycling bin having a first opening; a conveying mechanism comprising a first slide rail disposed on one side of the conveyor belt, the upper end of the first slide rail being disposed near the first position of the conveyor belt, the other end of the first slide rail extending obliquely downward to above the first opening; and a gripper movably disposed within the housing, the gripper being disposed above the first position of the conveyor belt, the gripper being movable to push a bottle located at the first position onto the first slide rail.

[0024] Another technical solution described above has the following advantages or beneficial effects: the gripper is positioned above the first position and can be moved by a robotic arm or sliding structure to precisely push the metal bottle, which is stationary at the first position, onto the first slide rail, completing the transition from the conveyor belt to the slide rail. Once the metal bottle is controlled by the controller to remain at the first position, the gripper is activated to move, pushing the bottle to the upper end of the first slide rail. The bottle then slides down the inclined first slide rail, falls through the first opening into the first recycling bin, and the recycling of the metal bottle is completed.

[0025] In some embodiments of this application, a bottle recycling device is provided. The conveying mechanism includes a base portion rotatably disposed above a first position of the conveyor belt. Multiple grippers are provided and arranged circumferentially along the base portion. A third driving member is connected to the base portion for driving the base portion to rotate, thereby causing the multiple grippers to rotate relative to the conveyor belt, so that the multiple grippers can sequentially push the bottles at the first position.

[0026] Another technical solution in the above-mentioned technical solution has the following advantages or beneficial effects: by setting multiple grippers arranged circumferentially, the next gripper approaches the working position after the base rotates, without waiting for reset, thereby realizing continuous pushing without interval. When there is continuous bottle feeding, the arrangement of multiple grippers can effectively improve the processing efficiency of metal bottles and avoid conveyor belt congestion caused by the lag in gripper action.

[0033] Figure 1 This is a schematic diagram of a bottle recycling device according to an embodiment of this application.

[0034] like Figure 1As shown, the bottle recycling device provided in this embodiment of the present invention includes a housing 1, which forms the outer shell of the bottle recycling device. The housing 1 can adopt a hollow structure such as a cuboid. It should be noted that the housing 1 can also adopt other hollow shell structures.

[0035] Figure 2 for Figure 1 A partial schematic diagram; Figure 3 for Figure 2 A schematic diagram of one side. It should be noted that this diagram is for ease of showing the internal structure of the bottle recycling device. Figure 2 for Figure 1 A schematic diagram showing the concealed portion of the casing.

[0036] like Figure 2 and Figure 3 As shown, in some embodiments, the bottle recycling device includes a bottle feeding component 2, which is disposed on the shell 1 and serves as the feeding end for the bottle to enter the bottle recycling device.

[0037] Figure 4 for Figure 3 A cross-sectional schematic diagram of the inlet bottle assembly.

[0038] like Figure 4 As shown, in some embodiments, the bottle feeding assembly 2 includes a feeding cylinder 21. One end of the feeding cylinder 21 is exposed outside the outer wall of the housing 1, and the other end of the feeding cylinder 21 extends into the interior of the housing 1. The feeding cylinder 21 has an annular structure, and the annular inner surface of the feeding cylinder 21 forms a feeding channel 201. An inlet 202 is provided at the end exposed outside the housing 1 for receiving bottles. The other annular end of the feeding cylinder 21 extends into the interior of the housing 1.

[0039] The annular inner surface of the feeding cylinder 21 forms a closed feeding channel 201. The feeding channel 201 is annular and can guide the bottle to avoid rolling or displacement of the bottle.

[0040] The bottle feeding assembly 2 may include a first sensor 22, which is mounted on the feeding cylinder 21. The first sensor 22 is used to sense metal bottles and generate a first detection signal. In this way, metal bottles, such as aluminum cans, can be detected in real time when they enter the feeding channel 201, and the first sensor 22 can generate a corresponding first detection signal.

[0041] The bottle feeding assembly 2 may include a second sensor 23, which is disposed on the feeding cylinder 21. The second sensor 23 may be spaced apart from the end of the first sensor 22 away from the feeding port 202. The second sensor 23 is used to sense non-metallic bottle bodies and generate a second detection signal. In this way, non-metallic bottle bodies, such as plastic bottles and glass bottles, can be detected in real time by the second sensor 23 when they enter the feeding channel 201, and the second sensor 23 can generate a corresponding second detection signal.

[0042] Thus, by setting the first sensor 22 and the second sensor 23 on the bottle feeding assembly 2 respectively, the material identification process can be brought forward to the bottle feeding stage, which greatly shortens the sorting and processing time, reduces the processing time in the subsequent conveying process, and significantly improves the sorting efficiency of the bottle recycling device.

[0043] like Figure 2 and Figure 3 As shown, in some embodiments, the bottle recycling device includes a conveying mechanism 3, which is disposed inside the housing 1. The conveying mechanism 3 is used to move the bottles put into the housing 1 to different recycling locations.

[0044] The conveying mechanism 3 includes a first driving member 31 and a conveyor belt 32. The first driving member 31 is disposed inside the housing 1 and is drively connected to the conveyor belt 32 for driving the conveyor belt 32 to move during startup. The input end of the conveyor belt 32 is located at the end of the feed channel 201 away from the inlet 202. The conveyor belt 32 has first positions 301 and second positions 302 spaced apart along its conveying direction. The first driving member 31 can be a drive motor. In some embodiments, the bottle recycling device further includes a controller 4, which is connected to a first sensor 22, a second sensor 23, and a first drive unit 31. The controller 4 is configured to: control the first drive unit 31 to stop based on a first detection signal generated by the first sensor 22, so that the bottles on the conveyor belt 32 are located at a first position 301; and control the first drive unit 31 to stop based on a second detection signal generated by the second sensor 23, so that the bottles on the conveyor belt 32 are located at a second position 302.

[0045] Specifically, the controller 4 controls the first drive unit 31 to stop based on the first detection signal sensed by the first sensor 22 and the second detection signal sensed by the second sensor 23. After the bottles enter the conveyor belt 32 through the feeding channel 201, metal bottles are positioned at the first position 301 on the conveyor belt 32, while non-metallic bottles are positioned at the second position 302, thus achieving separate parking for bottles of different materials. Furthermore, the first position 301 and the second position 302 on the conveyor belt 32 are spaced apart along the conveying direction, which helps to clearly distinguish the collection areas for metal and non-metal bottles, avoids mixing of bottles of different materials, and improves the accuracy of classification.

[0046] In existing technologies, automatic beverage bottle recycling devices mainly rely on different sensors installed on the conveyor belt 32 to identify and differentiate the materials of the bottles, thereby sorting and classifying them for recycling. However, since the identification and classification process only begins when the beverage bottles enter the conveyor belt 32, the identification and classification process takes longer, resulting in low sorting efficiency.

[0047] In the technical solution of this application, an annular feeding channel 201 is formed in the feeding cylinder 21 of the bottle feeding assembly 2. After the bottle enters from the feeding port 202, it reaches the conveyor belt 32 after passing through the feeding channel 201. A first sensor 22 and a second sensor 23 are respectively installed on the feeding cylinder 21. During the process of the bottle passing through the feeding channel 201, the first sensor 22 and the second sensor 23 can identify whether the bottle material is metal or non-metal and send detection signals to the controller 4 in real time. Thus, the identification action of the bottle recycling device is synchronized with the bottle feeding process, without waiting for the bottle to enter the conveyor belt 32 before starting. When the bottle reaches the input end of the conveyor belt 32, the controller 4 has already obtained its material information, which helps to shorten the overall processing time of a single bottle from feeding to sorting completion.

[0048] Furthermore, the conveyor belt 32 is pre-set with a first position 301 corresponding to metal bottles and a second position 302 corresponding to non-metal bottles. The controller 4 obtains a first detection signal and a second detection signal based on the bottle feeding stage of the bottle feeding component 2, and then controls the first drive unit 31 to stop at the corresponding position. For example, when a metal bottle passes through the feeding cylinder 21, the first sensor 22 triggers the first detection signal, and the controller 4 pre-plans the running distance of the conveyor belt 32. When the bottle is sent to the first position 301 by the conveyor belt 32, it stops immediately. For non-metal bottles, the second sensor 23 triggers the signal, and the controller 4 controls it to stop at the second position 302. In this process, the operation of the conveyor belt 32 sends the identified bottles to the preset positions, thereby solving the problem that existing traditional bottle recycling devices only detect and classify bottles when they start conveying them. This reduces the ineffective running time of the conveyor structure, allows more bottles to be processed per unit time, and significantly improves the classification efficiency.

[0049] like Figure 4 As shown, in some embodiments, the first sensor 22 may include a primary coil 221, which may be wound around the circumferential sidewall of the feeding cylinder 21. The primary coil 221 is energized and used to generate a magnetic field.

[0050] The first sensor 22 may include a primary coil 222 and a secondary coil 223. The primary coil 222 is distributed at both ends of the primary coil 221 along the axial direction. The primary coil 222 is wound around the circumferential sidewall of the feeding cylinder 21 and is located at the end of the primary coil 221 near the feeding port 202. The secondary coil 223 is located at the end of the primary coil 221 away from the primary coil 222.

[0051] In this design, the first-stage coil 222 and the second-stage coil 223 are wound in the same direction. The tail end of the first-stage coil 222 is connected to the tail end of the second-stage coil 223, or the head end of the first-stage coil 222 is connected to the head end of the second-stage coil 223, so that when the metal bottle passes through the feed channel 201, the polarities of the potential output by the first-stage coil 222 and the second-stage coil 223 are opposite.

[0052] Specifically, when a metal bottle passes through the feed channel 201, it cuts the magnetic field generated by the primary coil 221, inducing eddy currents inside the metal. As the metal bottle sequentially passes through the primary coil 222, the secondary coil 221, and the secondary coil 223, the two secondary coils generate induced potentials due to the eddy currents. However, due to their different positions and connections, the potentials output by the primary coil 222 and the secondary coil 223 have opposite polarities—one is positive and the other is negative. This effectively improves the accuracy and anti-interference capability of metal bottle identification. Since non-metallic bottles (plastic, glass) do not generate eddy currents, the induced potential changes in the two secondary coils are minimal, thus effectively distinguishing between metal and non-metallic bottles.

[0053] like Figure 4 As shown, in some embodiments, the second sensor 23 may be configured as a diffuse reflection sensor, which may be located at one end of the bottle-feeding assembly 2 near the conveyor belt 32.

[0054] In some embodiments, the bottle-dispensing assembly 2 may also be equipped with a light assembly 24, which can switch colors according to the sensing process within the bottle-dispensing assembly 2. For example, when a bottle enters the bottle-dispensing assembly 2 and is sensed by the first sensor 22 or the second sensor 23, the light assembly 24 can display a red light, indicating that the bottle-dispensing assembly 2 is performing analysis and preventing the next bottle from entering and affecting the current sensing process. After the bottle enters the conveyor belt 32, the light assembly 24 can display a green light, allowing the user to continue dispensing bottles.

[0055] Figure 5 for Figure 2 A diagram of the other side.

[0056] like Figure 3 and Figure 5 As shown, in some embodiments, the conveying mechanism 3 may include a first position sensor 321, which is disposed corresponding to a first position 301 of the conveyor belt 32, so that when the bottle moves to the first position 301, the first position sensor 321 can generate a first control signal. It should be noted that the first position sensor 321 being disposed corresponding to the first position 301 of the conveyor belt 32 can mean that the first position sensor 321 can be arranged directly opposite the first position 301 of the conveyor belt 32, for example, the first position sensor 321 can be arranged directly above the first position 301. Alternatively, the first position sensor 321 can also be arranged opposite to one side of the first position 301.

[0057] The controller 4 is connected to the first position sensor 321. When the controller 4 senses the first detection signal generated by the first sensor 22 and the first position sensor 321 generates the first control signal, the controller 4 controls the first drive unit 31 to stop.

[0058] Specifically, by setting the first position sensor 321 to correspond to the first position 301 of the conveyor belt 32, the first position sensor 321 can sense the bottle that has reached the first position 301, so that when the bottle moves to the first position 301, the first position sensor 321 can generate a first control signal.

[0059] In this way, when the first sensor 22 detects the metal bottle and sends a first detection signal, and the first position sensor 321 detects that the bottle has moved to the first position 301 and sends a first control signal, the controller 4 issues a stop command to control the first drive unit 31, causing the conveyor belt 32 to stop moving, thereby accurately stopping the metal bottle at the first position 301 of the conveyor belt 32. The first detection signal sensed by the first sensor 22 serves as the trigger condition for stopping the first drive unit 31, while the first control signal sensed by the first position sensor 321 upon the bottle reaching the first position 301 serves as the execution condition. The bottle recycling device initially identifies the material of the bottle at the bottle feeding assembly 2, determines the bottle's position through the first position sensor 321, and finally executes the stop command. This makes the controller 4's control of the conveyor belt 32 more consistent with the actual operating state, improving the stability and anti-interference capability of the bottle recycling device during continuous operation.

[0060] Figure 6 for Figure 5 A schematic diagram showing the interaction between the central conveyor mechanism and the first recycling bin; Figure 7 for Figure 1 A cross-sectional schematic diagram.

[0061] like Figure 5 , Figure 6 and Figure 7 As shown, in some embodiments, the bottle recycling container includes a first recycling bin 11, which may be disposed inside the housing 1. The first recycling bin 11 is located below the first position 301 of the conveyor belt 32, and the top of the first recycling bin 11 has a first opening 101.

[0062] The conveying mechanism 3 may include a first slide rail 36 disposed on one side of the conveyor belt 32. The upper end of the first slide rail 36 is positioned near the first position 301 of the conveyor belt 32, and the other end of the first slide rail 36 extends downward at an angle above the first opening 101. The downward angle of the first slide rail 36 allows the bottle moving onto it to slide from the first position 301 of the conveyor belt 32 into the first recycling bin 11 under the guidance of the first slide rail 36, facilitating accurate movement of the bottle into the first recycling bin 11.

[0063] The conveying mechanism 3 may include a gripper 381, which is movably disposed inside the housing 1. The gripper 381 is disposed above the first position 301 of the conveyor belt 32. The gripper 381 is movable to push the bottle located at the first position 301 onto the first slide rail 36.

[0064] Specifically, the gripper 381 is movably positioned above the first position 301. It can be moved via a robotic arm or sliding structure to precisely push the metal bottle at the first position 301 towards the first slide rail 36, completing the transition from the conveyor belt 32 to the slide rail. Once the metal bottle is controlled by the controller 4 to remain at the first position 301, the gripper 381 is activated to move, pushing the bottle to the upper end of the first slide rail 36. The bottle then slides down the inclined first slide rail 36, falling through the first opening 101 into the first recycling bin 11, completing the recycling of the metal bottle.

[0065] like Figure 7 As shown, in some embodiments, the conveying mechanism 3 may include a base portion 382, ​​rotatably disposed above a first position 301 of the conveyor belt 32. Multiple grippers 381 are provided, arranged circumferentially along the base portion 382.

[0066] The third drive member 383 is connected to the base part 382 in a transmission manner. The third drive member 383 is used to drive the base part 382 to rotate, thereby causing multiple grippers 381 to rotate relative to the conveyor belt 32, so that the multiple grippers 381 can be pushed sequentially towards the bottle on the first position 301. The third drive member 383 can be configured as a drive motor.

[0067] The third driving member 383 can drive the base portion 382 to rotate around an axis, thereby causing multiple grippers 381 to rotate circumferentially along the base portion 382. For example, the number of grippers 381 can be four, and the four grippers 381 can be evenly arranged circumferentially along the base portion 382, ​​for example, in a radial distribution. Each time the third driving member 383 drives the base portion 382 to rotate 90°, the gripper 381 located at the first position 301 pushes the bottle towards the first slide rail 36, and the next gripper 381 can move to the first position 301.

[0068] Specifically, after the metal bottle stops at the first position 301, the third driving component 383 drives the base part 382 to rotate, causing the first gripper 381 to rotate above the first position 301. As the gripper 381 rotates with the base part 382, ​​it pushes the bottle towards the first slide rail 36. After the push is completed, the gripper 381 continues to rotate away with the base part 382, ​​and the next gripper 381 enters the working position in sequence, waiting for the push command of the next metal bottle.

[0069] In this embodiment, by setting multiple grippers 381 arranged circumferentially, the base 382 rotates so that after one gripper 381 completes the push, the next gripper 381 approaches the working position without waiting for reset, thus achieving continuous push without interval. When there is continuous bottle feeding, the arrangement of multiple grippers 381 can effectively improve the processing efficiency of metal bottles and avoid congestion of the conveyor belt 32 caused by the lag in the action of the grippers 381.

[0070] On the other hand, the arrangement of the gripper 381 and the base 382 replaces the linear reciprocating motion of the gripper 381 with circular motion, which requires less installation space in the horizontal space and eliminates the need for additional guide rails and other components, further simplifying the internal structure and facilitating a compact layout inside the bottle recycling device.

[0071] In some other embodiments, the gripper 381 may be a single gripper that can be driven by a lead screw, crank, or rack and pinion mechanism.

[0072] like Figure 3 As shown, in some embodiments, the controller 4 is connected to the second position sensor 322, which is correspondingly positioned to the second position 302 of the conveyor belt 32. When the bottle moves to the second position 302, the second position sensor 322 generates a second control signal. It should be noted that the second position sensor 322 corresponding to the second position 302 of the conveyor belt 32 can mean that the second position sensor 322 can be arranged directly opposite the second position 302 of the conveyor belt 32, for example, directly above the second position 302. Alternatively, the second position sensor 322 can also be arranged opposite to one side of the second position 302.

[0073] The controller 4 is connected to the second position sensor 322. When the controller 4 senses the second detection signal generated by the second sensor 23 and the second position sensor 322 generates the second control signal, the controller 4 controls the first drive unit 31 to stop.

[0074] Specifically, by setting the second position sensor 322 to correspond to the second position 302 of the conveyor belt 32, the second position sensor 322 can sense the bottle that has reached the second position 302, so that when the bottle moves to the second position 302, the second position sensor 322 can generate a second control signal.

[0075] In this way, when the second sensor 23 detects the non-metallic bottle and sends a second detection signal, and the second position sensor 322 detects that the bottle has moved to the second position 302 and sends a second control signal, the controller 4 sends a stop command to control the first drive unit 31, so that the conveyor belt 32 stops moving. This ensures that the non-metallic bottle is accurately stopped at the second position 302 of the conveyor belt 32, providing an accurate spatial reference for the further classification or collection of the non-metallic bottle and reducing problems such as classification errors and bottle jamming caused by inaccurate positioning.

[0076] In this system, the second detection signal sensed by the second sensor 23 serves as the trigger condition for stopping the first drive unit 31, while the second control signal sensed by the second position sensor 322 when the bottle reaches the second position 302 serves as the execution condition. The bottle recycling device initially identifies the material of the bottle at the bottle feeding assembly 2, determines the position of the bottle through the first position sensor 321, and finally executes the shutdown, making the controller 4's control of the conveyor belt 32 more consistent with the actual operating state and improving the stability and anti-interference ability of the bottle recycling device during continuous operation.

[0077] In some specific embodiments, the first position sensor 321 and the second position sensor 322 may be sensors of the type such as photoelectric sensors, inductive proximity sensors, micro switches, limit switches, etc.

[0078] like Figure 7 As shown, in some embodiments, a third sensor 323 may be provided on the conveyor belt 32. The third sensor 323 is disposed corresponding to the second position 302 of the conveyor belt 32, and is used to detect the weight of the bottle on the conveyor belt 32. The third sensor 323 may be located at the bottom of the conveyor belt 32. When the third sensor 323 detects that the weight of the bottle on the conveyor belt 32 is greater than a preset threshold, the third sensor 323 can generate a third control signal. Figure 8 This is a schematic diagram of the sorting arm in one state. Figure 9 This is a schematic diagram of another state of the sorting arm.

[0079] like Figure 8 and Figure 9 As shown, the conveying mechanism 3 may include a sorting arm 33 and a second driving member 34. The second driving member 34 is connected to the sorting arm 33 in a transmission manner and is used to drive the sorting arm 33 to rotate. The lower end of the sorting arm 33 can be rotatably connected to the interior of the housing 1. Specifically, a support 14 may be provided inside the housing 1, and the sorting arm 33 can be rotatably connected to the support 14. The rotatable connection of the sorting arm 33 allows the sorting arm 33 to flexibly switch states, and through the setting of the sorting arm 33, non-metallic bottles can be further sorted.

[0080] The sorting arm 33 is equipped with a sorting channel 304, which is arranged at an angle downwards. When the sorting arm 33 rotates to the point where the sorting channel 304 connects with the conveyor belt 32, the bottle can enter the sorting channel 304 from the conveyor belt 32. The downward-angled arrangement of the sorting channel 304 facilitates the rapid passage of the bottle within the sorting arm 33, avoiding the risk of collision and stagnation.

[0081] The controller 4 is connected to the second drive unit 34 and the third sensor 323 respectively. The controller 4 can control the second drive unit 34 to work according to the third control signal, drive the sorting arm 33 to rotate, so that the upper end of the sorting channel 304 is connected to the end of the conveyor belt away from the input port 202, or keep the upper end of the sorting channel 304 connected to the end of the conveyor belt away from the input port 202.

[0082] Specifically, by setting a first sensor 22 and a second sensor 23 on the bottle feeding assembly 2, the bottles made of metal and non-metal materials can be initially identified. Then, at the stopping position of the bottle at the second position 302, a third sensor 323 is set on the conveyor belt 32 to detect the weight of the bottle, thereby performing secondary classification and identification of non-metallic bottles.

[0083] In practical recycling scenarios, non-metallic bottles generally include plastic and glass bottles, with glass bottles typically being heavier than plastic bottles. By setting a preset threshold for detection by the third sensor 323, the weight can be used to distinguish between glass and plastic. Generally, glass bottles are much heavier than plastic bottles. The preset threshold can be set based on the weight characteristics of common bottle materials; this solution does not impose such limitations.

[0084] When the third sensor 323 detects that the weight of the bottle on the conveyor belt 32 exceeds a preset threshold, and the bottle is made of heavy non-metallic glass, such as a glass bottle, the controller 4 generates a third control signal based on the third sensor 323. The second drive unit 34 then triggers the sorting arm 33 to move, connecting the upper end of the sorting channel 304 with the end of the conveyor belt away from the inlet 202. At this time, the first drive unit 31 drives the conveyor belt 32 to move, thereby transferring the glass bottle into the sorting channel 304 and moving it to other collection locations through the sorting channel 304.

[0085] Furthermore, when the initial position of the sorting arm 33 is set such that the upper end of the sorting arm 33 is separated from the end of the conveyor belt away from the inlet 202, the second drive member 34 drives the sorting arm 33 to rotate so that the upper end of the sorting channel 304 is connected to the end of the conveyor belt away from the inlet 202; when the initial position of the sorting arm 33 is set such that the upper end of the sorting arm 33 is connected to the end of the conveyor belt away from the inlet 202, the second drive member 34 may not drive the sorting arm 33 to move so that the upper end of the sorting channel 304 remains connected to the end of the conveyor belt away from the inlet 202.

[0086] In some embodiments, the second drive member 34 may be a drive mechanism such as a cylinder or an electric actuator.

[0087] In some embodiments, the first position 301 may be located at one end of the conveyor belt 32 near the bottle-feeding assembly 2, or at one end of the conveyor belt 32 away from the bottle-feeding assembly 2.

[0088] Specifically, if the bottle is made of metal, it can first reach the first position 301 on the conveyor belt 32 and stop there, awaiting the next sorting and recycling action of the bottle recycling device. If the bottle is made of non-metallic material, it continues to move on the conveyor belt 32 to the second position 302, where the third sensor 323 detects the weight of the bottle and further distinguishes whether the bottle is made of glass or plastic based on the weight, awaiting the next sorting and recycling action of the bottle recycling device.

[0089] like Figure 8 As shown, in some embodiments, the bracket 14 inside the housing 1 is provided with a sliding groove 105. The conveying mechanism 3 may include a rotating arm 39, one end of which is connected to a second driving member 34, and the other end of which is slidably connected in the sliding groove. The rotating arm 39 is connected to the sorting arm 33. When the second driving member 34 moves to drive one end of the rotating arm 39 to rotate, the other end of the rotating arm 39 moves along the trajectory of the sliding groove 105 to drive the sorting arm 33 to rotate relative to the conveying track, thereby realizing the switching between working and non-working states.

[0090] Specifically, the second drive component 34 can be a drive assembly such as a cylinder or an electric push rod. In this way, the second drive component 34 can quickly transmit power to the rotating arm 39 through telescopic movement to efficiently drive the sorting arm 33 to rotate.

[0091] like Figure 8 and Figure 9 As shown, in some embodiments, the bottle recycling device may include a second recycling bin 12, which is located below the end of the conveyor belt 32 away from the inlet 202, and the top of the second recycling bin 12 has a second opening 102. Specifically, the second opening 102 of the second recycling bin 12 may be located near the second position 302 of the conveyor belt 32.

[0092] When the third sensor 323 detects that the weight of the bottle on the conveyor belt 32 is less than a preset threshold, the third sensor 323 can generate a fourth control signal. The controller 4 can control the second drive unit 34 to work according to the fourth control signal, driving the sorting arm 33 to rotate so that the upper end of the sorting channel 304 is separated from the end of the conveyor belt away from the input port 202, or keeps the upper end of the sorting channel 304 separated from the end of the conveyor belt away from the input port 202.

[0093] When the third sensor 323 detects that the weight of the bottle at the second position 302 is less than a preset threshold, and the bottle is a lightweight non-metallic material, such as a plastic bottle, the third sensor 323 generates and sends a fourth control signal to the controller 4.

[0094] When the third sensor 323 detects that the weight of the bottle on the conveyor belt 32 is less than a preset threshold, and the bottle is made of lightweight non-metallic glass, such as a plastic bottle, the controller 4 can generate a third control signal based on the third sensor 323, and the second drive unit 34 will trigger the sorting arm 33 to move, causing the upper end of the sorting channel 304 to separate from the end of the conveyor belt away from the inlet 202. The first drive unit 31 drives the conveyor belt 32 to move, and the plastic bottle falls directly from the end of the conveyor belt 32 and enters the second recycling bin 12 through the second opening 102.

[0095] Specifically, when the initial position of the sorting arm 33 is set such that its upper end is separated from the end of the conveyor belt away from the inlet 202, the second drive member 34 does not need to move the sorting arm 33, thus keeping the upper end of the sorting channel 304 separated from the end of the conveyor belt away from the inlet 202. When the initial position of the sorting arm 33 is set such that its upper end is connected to the end of the conveyor belt away from the inlet 202, the second drive member 34 moves the sorting arm 33, thus separating the upper end of the sorting channel 304 from the end of the conveyor belt away from the inlet 202. In this way, the bottles at the end of the conveyor belt 32 can fall into the second recycling bin 12 by gravity, avoiding entering the sorting channel 304.

[0096] In this way, the glass bottles are guided to the sorting channel 304 by the sorting arm 33, and the plastic bottles fall into the second recycling bin 12 by gravity. The switching between the two paths is automatically completed by the controller 4 based on sensor signals. This sorting process increases the throughput per unit time, and the plastic bottles fall freely into the second recycling bin 12, avoiding complex conveying mechanisms and reducing the risk of mechanical failure.

[0097] like Figure 8 and Figure 9 As shown, in some implementations, the conveying mechanism 3 may include a guide 35, which is located below the end of the conveyor belt 32 away from the inlet 202. Specifically, one end of the guide 35 may be fixedly connected to the bottom of the conveyor belt, or it may be connected to the bracket 14 and thus arranged on the end of the conveyor belt 32 away from the inlet 202.

[0098] The guide member 35 is provided with a guide groove 303, which is arranged at an angle downwards, and the lower end of the guide groove 303 is located above the second opening 102.

[0099] Specifically, the guide 35 is installed below the end of the conveyor belt 32 away from the inlet 202. The upper end of the guide trough 303 receives the plastic bottles falling from the end of the conveyor belt 32, and the lower end of the guide trough 303 can be aligned above the second opening 102 of the second recycling bin 12, forming a transition channel from the end of the conveyor belt 32 to the second recycling bin 12. The inclined setting of the guide trough 303 allows gravity to assist the sliding of the bottles, completing the conveying without additional power.

[0100] Due to the irregular shape and light weight of plastic bottles, they are easily affected by air resistance and may shift position when falling. The inertia of the conveyor belt 32 may also cause the bottle to be thrown at a slight angle, deviating from the second opening 102. In this embodiment, by installing the guide 35 below the end of the conveyor belt 32 away from the inlet 202, the guide groove 303 forms a constrained, fixed channel. After falling, the bottle is restricted to sliding within the groove, allowing it to fall precisely into the opening of the second recycling bin 12 along the guide groove 303. This helps to avoid the problem of the bottle shifting from the second recycling bin 12 during its descent.

[0101] like Figure 8 and Figure 9 As shown, in some embodiments, the bottle recycling device may include a third recycling bin 13, the top of which has a third opening 103. The third recycling bin 13 may be positioned close to the second recycling bin 12, thereby achieving a compact layout inside the bottle recycling device.

[0102] The conveying mechanism 3 includes a second slide rail 37, which is arranged at an angle downwards. The upper end of the second slide rail 37 is connected to the lower end of the sorting arm 33, and the lower end of the second slide rail 37 is located above the third opening 103. When the upper end of the sorting channel 304 is connected to the end of the conveyor belt away from the input port 202, the bottles of the conveyor belt 32 can enter the second slide rail 37 through the sorting channel 304 and enter the third recycling bin 13 through the third opening 103.

[0103] Specifically, the second slide rail 37 is arranged at an angle downwards. The upper end of the second slide rail 37 is connected to the lower end of the sorting arm 33, and then connects to the outlet of the sorting channel 304. The lower end of the second slide rail 37 extends above the third opening 103 of the third recycling bin 13, forming a continuous conveying path from the sorting arm 33 to the third recycling bin 13. When the third sensor 323 detects that the weight of the bottle is greater than a preset threshold, the upper end of the sorting arm 33 connects to the end of the conveyor belt 32. The conveyor belt 32 delivers the bottle to its end, causing it to enter the sorting channel 304 of the sorting arm 33. The bottle slides down the inclined sorting channel 304 to the second slide rail 37, and then slides into the third recycling bin 13 via the inclined second slide rail 37, completing the recycling of the heavy glass bottle. The inclined arrangement utilizes gravity to assist the sliding of the bottle, completing the conveying without additional power, further simplifying the transmission structure of the bottle recycling device.

[0104] Glass bottles can be sorted through the sorting channel 304 and the second slide rail 37 and then recycled to the third recycling bin 13. Plastic bottles can be recycled to the second recycling bin 12 under the action of the guide groove 303, thus realizing the further sorting and recycling of non-metallic bottles.

[0105] Figure 10 for Figure 9 An exploded view of the third recycling bin in the middle.

[0106] like Figure 10 As shown, in some embodiments, the bottle recycling device may include a guide plate 131, which is movably disposed within the third recycling bin 13. The top wall of the guide plate 131 is inclined relative to the horizontal plane, so that the guide plate 131 forms an inclined upper end and a lower end arranged vertically. The upper end of the guide plate 131 is arranged below the end of the second slide rail 37 away from the sorting arm 33. When the bottle leaves from the end of the second slide rail 37, it will first fall onto the top wall of the upper end of the guide plate 131 and can move downward along the inclined guide plate 131 to the lower end of the guide plate 131.

[0107] The top wall of the guide plate 131 and the side wall of the third recycling bin 13 enclose a receiving space 104, which is used to receive the bottle.

[0108] The bottle recycling device may include a lifting and moving assembly 132, which is disposed within the third recycling bin 13. The lifting and moving assembly 132 is convexly connected to a guide plate 131 and is used to drive the guide plate 131 to perform lifting and lowering movements. Specifically, a space for accommodating the lifting and moving assembly 132 can be formed between the bottom of the guide plate 131 and the side wall of the recycling bin. The lifting and moving assembly 132 may be disposed between the bottom wall of the guide plate 131 and the bottom of the recycling bin. The lifting and moving assembly 132 is convexly connected to the guide plate 131 and is used to drive the guide plate 131 to perform lifting and lowering movements, so that the guide plate 131 can rise or fall along the height direction of the recycling bin.

[0109] Specifically, after the bottle enters the second slide rail 37 through the sorting channel 304, it will move downwards along the second slide rail 37 at an angle. The end of the second slide rail 37 away from the sorting arm 33 corresponds to the opening of the third recycling bin 13. At the same time, the upper end of the guide plate 131 inside the third recycling bin 13 is located below the end of the second slide rail 37 away from the sorting arm 33. When the glass bottle leaves the end of the second slide rail 37, it will first fall onto the top wall of the inclined guide plate 131. Since the top wall of the guide plate 131 is inclined relative to the horizontal plane, it can prevent the bottle from falling vertically. The bottle slides down naturally along the inclined surface of the guide plate 131 by gravity. This can greatly reduce the impact force during the falling process. For fragile glass bottles or bottles made of other materials, it can effectively prevent breakage or other damage during the transportation to the recycling bin.

[0110] Furthermore, the guide plate 131 and the side wall of the third recycling bin 13 enclose a receiving space 104 for storing fallen glass bottles. The lifting and moving assembly 132 is connected to the guide plate 131 and can drive the guide plate 131 to move up and down along the height direction of the third recycling bin 13. When there are few bottles in the receiving space 104, the lifting and moving assembly 132 drives the guide plate 131 to move upward, bringing it closer to the opening of the third recycling bin 13. At this time, the drop height of the bottle from the lower end of the second slide rail 37 to the guide plate 131 is minimal, further reducing impact. As the number of bottles gradually increases, the receiving space 104 is occupied. The lifting and moving assembly 132 drives the guide plate 131 to move downward, increasing the volume of the receiving space 104, while still keeping the drop height of the bottle from the lower end of the second slide rail 37 to the guide plate 131 at a low level. In this way, the size of the holding space 104 can be dynamically adjusted according to the amount of bottles, which not only ensures low impact when there are a few bottles, reducing the probability of glass bottle breakage and improving the integrity after recycling; but also expands the space by moving the guide plate 131 downward when there are more bottles, avoiding bottle crushing damage due to insufficient space, while making full use of the volume of the third recycling box 13.

[0111] In some embodiments, the lifting and moving assembly 132 may include a linkage assembly 1321 and a fourth driving member 1322. The fourth driving member 1322 is tractively connected to the linkage assembly 1321, and the fourth driving member 1322 is telescopic to drive the linkage assembly 1321 to extend and retract vertically, thereby driving the guide plate 131 to perform lifting and lowering movements.

[0112] The linkage assembly 1321 can be disposed inside the third recycling bin 13 and located at the bottom of the guide plate 131, and the linkage assembly 1321 is pultrusively connected to the guide plate 131. When the fourth drive member 1322 extends, the fourth drive member 1322 drives the linkage assembly 1321 to extend relative to the bottom of the third recycling bin 13, thereby causing the guide plate 131 to move upward. When the fourth drive member 1322 retracts, the fourth drive member 1322 drives the linkage assembly 1321 to retract relative to the bottom of the third recycling bin 13, thereby causing the guide plate 131 to move downward.

[0113] Among them, by setting a connecting rod assembly 1321 at the bottom of the guide plate 131, the connecting rod assembly 1321 can serve as a structure to drive the guide plate 131 to rise and fall, and can also serve as a support structure at the bottom of the guide plate 131. The connecting rod assembly 1321 can distribute the driving force of the fourth driving member 1322 to multiple force points of the guide plate 131 through the transmission characteristics of multi-rod linkage, so as to avoid the guide plate 131 tilting or deforming due to single-point force.

[0114] Specifically, the fourth drive component 1322 can be a drive assembly such as a cylinder or an electric push rod. In this way, the extension and retraction action of the first drive component 31 can be quickly transmitted to the linkage assembly 1321, causing the guide plate 131 to rise and fall instantly.

[0115] In other embodiments, the lifting and moving assembly 132 may employ a screw drive structure, a rack and pinion drive structure, or a hydraulic telescopic cylinder structure, etc.

[0116] The above are merely specific embodiments of this application, but the scope of protection of this application is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the scope of the technology disclosed in this application should be included within the scope of protection of this application. Therefore, the scope of this application is limited only by the appended claims.
