Description

Technical Field

[0001] This utility model belongs to the field of beverage bottle recycling technology, and in particular relates to a clean beverage bottle recycling device. Background Technology

[0002] With increasing environmental awareness, beverage bottle recycling technology has become a crucial link in resource recycling. Currently, beverage bottle recycling devices on the market generally suffer from technical defects, hindering recycling efficiency and equipment reliability. Firstly, existing devices rely on overly simplistic methods to determine the cleanliness of beverage bottles, often depending solely on visual inspection or a single weight threshold, failing to accurately identify residual liquid or foreign matter in bottles of different sizes. This crude inspection method easily leads to bottles containing liquid entering the squeezing process, where liquid overflows and contaminates the equipment under mechanical pressure. Simultaneously, embedded solid foreign matter may cause the squeezing mechanism to jam or even break. Secondly, traditional recycling devices generally use conveyor belt structures. This design not only requires complex components such as power rollers and guide plates but also faces problems such as large equipment footprint and difficult maintenance of the transmission system. Conveyor belts are prone to wear and motor overload during long-term operation, resulting in high downtime rates. Furthermore, most mainstream squeezing mechanisms use a spiral propulsion compression method. This technology inherently suffers from long power transmission chains and high squeezing force losses, resulting in insufficient effective squeezing force per unit of energy consumption, severely impacting processing efficiency. These technological shortcomings have become key bottlenecks restricting the upgrading of equipment in the industry. Utility Model Content

[0005] Furthermore, the platform has two sliding rods, and the two ends of the two platform sliding rods are connected to the top of the first support plate and the second support plate respectively through sliding rod support seats.

[0006] Furthermore, a sensor connector is slidably connected to the platform slide bar, the sensor connector is connected to a weight sensor, and the weight sensor is connected to the sliding platform.

[0011] Furthermore, the identification unit is a barcode scanning identification unit or a visual identification unit.

[0012] Furthermore, the fixed extrusion plate is connected to the first support plate via an extrusion plate fixing rod.

[0013] This utility model also provides a recycling method for a clean beverage bottle recycling device, specifically: the beverage bottle is placed vertically on a sliding platform through a limiting ring; the identification unit identifies the bottle's specifications and measures its weight using a weight sensor; the weight of the bottle is then determined according to the weight range of the corresponding specifications to determine whether there is liquid or debris in the bottle; if the weight exceeds the set range, the bottle is considered to contain liquid or debris, and the operator is prompted to return; if the weight does not exceed the set range, the bottle is considered to be free of liquid or debris, and the sliding platform slides along the platform slide rod under the drive of the first stepper motor; the limiting ring restricts the lateral movement of the beverage bottle; after the sliding platform slides away, the bottom of the beverage bottle loses support and falls into the squeezing chamber; at this time, the limiting baffle supports the bottom of the beverage bottle, and the second stepper motor drives the sliding squeezing plate to move towards the fixed squeezing plate to squeeze the beverage bottle; after the beverage bottle is crushed, the bottom loses support and is located above the discharge port; the second stepper motor drives the sliding squeezing plate to reset, and the beverage bottle falls into the collection bag.

[0014] Compared with existing technologies, the beneficial effects of this utility model are as follows: This utility model provides a clean beverage bottle recycling device that effectively solves the inherent defects of traditional equipment. First, it innovatively constructs a judgment system for bottle type recognition and dynamic weight detection, establishing a bottle type-weight feature database. Bottle specification information is accurately obtained through methods such as barcode scanning or visual recognition, and the weight parameters of standard empty bottles of the corresponding model in the database are retrieved simultaneously. Combined with a high-precision weight sensor, a gradient judgment of residue is achieved. This two-factor verification mechanism has higher detection sensitivity than the traditional single weight threshold method and can accurately identify abnormal weight fluctuations. Second, a vertical gravity conveying architecture replaces the traditional conveyor belt system. Through the precise cooperation of the platform slide bar and the stepper motor, the bottle is transferred between the detection station and the extrusion station without power. This design reduces the number of moving parts in the equipment, lowers the failure rate, and ensures that the bottle remains upright throughout the process, completely eliminating the risk of liquid leakage and achieving free-fall, unpowered conveying. Furthermore, a double-plate pressure-type high-efficiency extrusion mechanism has been developed. A stepper motor directly drives the sliding extrusion plate to form linear pressure, improving extrusion efficiency compared to the spiral extrusion method. The closed-loop control system, composed of a force sensor and a position switch, can quickly complete a single extrusion, significantly reducing unit energy consumption compared to traditional equipment. The organic integration of these three core technologies enables this utility model to achieve a triple breakthrough in equipment cleanliness, structural simplification, and energy economy while ensuring processing efficiency.

It should be noted that, unless otherwise specified, the embodiments and features in the embodiments of the present invention can be combined with each other, and the described embodiments are only some embodiments of the present invention, not all embodiments.

[0022] See Figure 1-3This embodiment describes a clean beverage bottle recycling device, which includes a frame, a sliding platform 14, a squeezing chamber, and a collection bag 11. A first support plate 18 and a second support plate 22 are connected to the frame. Platform slide rods 12 are connected to the tops of the first support plate 18 and the second support plate 22. The sliding platform 14 is slidably connected to the platform slide rods 12 and is connected to the output end of a first stepper motor 5. A weight sensor 4 is installed below the sliding platform 14. Beverage bottles 1 are placed vertically on top of the sliding platform 14, and limit rings are provided on the outer side of the beverage bottles 1. An identification unit 3 is installed on the frame, and the beverage bottles 1 are located on the sliding platform 14. When the beverage bottle 1 is in front of the identification unit 3, the squeezing chamber is located below the sliding platform 14. The squeezing chamber includes a fixed squeezing plate 19 and a sliding squeezing plate 21. A squeezing plate slide rod 23 is connected between the first support plate 18 and the second support plate 22. The sliding squeezing plate 21 is slidably connected to the squeezing plate slide rod 23. The sliding squeezing plate 21 is connected to the output end of the second stepper motor 7. The fixed squeezing plate 19 is connected to the first support plate 18. The fixed squeezing plate 19 and the sliding squeezing plate 21 are arranged opposite to each other. A limit baffle 20 is provided on the side of the squeezing chamber away from the fixed squeezing plate 19, and a discharge port is provided on the other side. A collection bag 11 is provided below the discharge port.

[0023] In this embodiment, the identification unit 3 is a barcode identification unit, a visual identification unit, or other existing bottle-type identification unit.

[0024] In this embodiment, there are two platform slide rods 12. The two ends of the two platform slide rods 12 are connected to the top ends of the first support plate 18 and the second support plate 22 respectively via slide rod support seats 15. A sensor connection seat 13 is slidably connected to the platform slide rod 12. The sensor connection seat 13 is connected to a weight sensor 4, and the weight sensor 4 is connected to the sliding platform 14. The first stepper motor 5 is mounted on the second support plate 22. The output end of the first stepper motor 5 is connected to one side of the sensor connection seat 13 via a first rope. A pulley assembly 16 is mounted on the first support plate 18. A second rope is connected to the other side of the sensor connection seat 13. The second rope passes through the pulley assembly 16 and is connected to a counterweight 17.

[0025] In this embodiment, the identification unit 3, weight sensor 4, first stepper motor 5, and second stepper motor 7 are all connected to the control system. The control system is connected to the display 2, which is mounted on the frame. A counter 6 is installed at the material discharge port. The sliding extrusion plate 21 is connected to the output of the second stepper motor 7 via a force sensor 8. A position switch mounting plate 25 is installed on the frame. Position switches 9 are installed on both the position switch mounting plate 25 and the sliding extrusion plate 21. The collection bag 11 is connected to the vibration motor 10. The counter 6, force sensor 8, position switches 9, and vibration motor 10 are all connected to the control system.

[0026] In this embodiment, the fixed extrusion plate 19 is connected to the first support plate 18 through the extrusion plate fixing rod 24, forming a rigid connection and allowing the position of the fixed extrusion plate 19 to be adjusted.

[0027] In this embodiment, a bottle cap bin 26 is provided on the frame, and a counter 6 is provided above the bottle cap bin 26. During recycling, the bottle caps of beverage bottles 1 can be unscrewed before disposal and placed in the bottle cap bin 26 for separate collection. Alternatively, they can be collected directly during the squeezing process without unscrewing them in advance. If the bottle caps of beverage bottles 1 are not unscrewed, the internal gas pressure of beverage bottles 1 will increase during the squeezing process. Before the internal gas pressure of beverage bottles 1 reaches its limit, the sliding squeezing plate 21 will break the threaded structure connected to the bottle cap, releasing the gas inside the bottle. Therefore, even if the bottle caps are not unscrewed in advance, it will not affect the squeezing process.

[0028] In this embodiment, a frame is used as the main support. A double-sided support frame is formed by a first support plate 18 and a second support plate 22. Two parallel platform slide rods 12 are fixed to the top of the two support plates by slide rod support seats 15, forming a horizontal moving track for the sliding platform 14. The sliding platform 14 forms a sliding pair with the platform slide rods 12 through a sensor connecting seat 13 at the bottom. A high-precision weight sensor 4 is installed below the sliding platform 14 to detect the weight of the beverage bottle 1 in real time. The lateral movement of the sliding platform 14 is driven by a first stepper motor 5. The first stepper motor 5 pulls one side of the sensor connecting seat 13 through a first rope, and the other side is connected to a counterweight block 17 through a second rope that passes around the pulley group 16 on the first support plate 18, forming a balanced traction system to ensure that the sliding platform 14 moves smoothly and with optimized energy consumption. An annular limit ring is provided above the sliding platform 14 to restrain the vertically placed beverage bottle 1 to maintain a vertical state, prevent it from tipping over, and ensure that the beverage bottle 1 does not move horizontally with the sliding platform 14. After the sliding platform 14 is removed, the beverage bottle 1 falls into the squeezing chamber under the action of gravity.

[0029] The identification unit 3 is fixed to the side of the frame, facing the bottle body area of ​​beverage bottle 1. This identification unit 3 uses existing identification methods such as barcode scanning or visual recognition technology to automatically acquire the specification and model information of beverage bottle 1 and match it with the bottle type-weight feature database pre-stored in the control system. The bottle type-weight feature database can be pre-compiled and input into the control system, eliminating the need for complex identification calculations and reducing identification costs. During the detection process, the weight sensor 4 compares the measured weight data with the weight parameters of standard empty bottles of the corresponding specifications in the database, and determines whether there is residual liquid or foreign matter inside the bottle through a gradient weight threshold. When the detected value exceeds the allowable fluctuation range, the display 2 immediately issues a warning to the operator to remove the abnormal bottle; bottles that meet the standards enter the squeezing chamber for subsequent processing.

[0030] The compression chamber is located directly below the sliding platform 14. The fixed compression plate 19 and the sliding compression plate 21 form a counter-pressure compression mechanism. The fixed compression plate 19 is rigidly connected to the first support plate 18 via the compression plate fixing rod 24, and the sliding compression plate 21 is slidably engaged with the compression plate slide rod 23. The sliding compression plate 21 is driven by the second stepper motor 7 to achieve linear reciprocating motion. A limit baffle 20 is provided at the bottom of the compression chamber to support the bottom of the falling beverage bottle 1 before compression, ensuring accurate positioning of the bottle. A force sensor 8 is installed between the sliding compression plate 21 and the output end of the second stepper motor 7 to monitor the compression force in real time and form a closed-loop control with the position switch 9. When the compression force reaches the preset value or the sliding compression plate 21 moves to the limit position, the drive automatically stops to avoid overload of the mechanism.

[0031] After the fixed extrusion plate 19 and the sliding extrusion plate 21 extrude the beverage bottle 1, since the limiting baffle 20 is only located on the side below the extrusion chamber away from the fixed extrusion plate 19, the beverage bottle 1 is no longer supported by the limiting baffle 20 after extrusion, but is directly above the discharge port. The sliding extrusion plate 21 resets, and the beverage bottle 1 falls into the collection bag 11. The vibration motor 10 works periodically to vibrate and flatten the beverage bottle 1 collected in the collection bag 11, so that the extruded beverage bottle 1 can make full use of the space inside the collection bag 11.

[0032] This embodiment describes a recycling method for a clean beverage bottle recycling device. Specifically, the beverage bottle 1 is placed vertically on the sliding platform 14, passing through a limiting stop ring. The identification unit 3 identifies the specifications of the beverage bottle 1, and the weight of the beverage bottle 1 is measured by the weight sensor 4. The system determines whether there is liquid or debris in the beverage bottle 1 according to the weight range of the corresponding specifications. If the weight exceeds the set range, the beverage bottle 1 is considered to contain liquid or debris, and the operator is prompted to return it. If the weight does not exceed the set range, the beverage bottle 1 is considered to be free of liquid or debris, and the sliding platform 14 is then closed. 4. Driven by the first stepper motor 5, the beverage bottle 1 slides along the platform slide bar 12. Under the action of the limit stop ring, the beverage bottle 1 is restricted from moving laterally. After the sliding platform 14 slides away, the bottom of the beverage bottle 1 loses support and falls into the squeezing chamber. At this time, the limit stop 20 supports the bottom of the beverage bottle 1. The second stepper motor 7 drives the sliding squeezing plate 21 to move towards the fixed squeezing plate 19 to squeeze the beverage bottle 1. After the beverage bottle 1 is crushed, the bottom loses support and is located above the discharge port. The second stepper motor 7 drives the sliding squeezing plate 21 to reset, and the beverage bottle 1 falls into the collection bag 11.

[0033] The above workflow can be specifically divided into four stages:

[0034] The first stage is bottle verification. The operator places the beverage bottle 1 upright on the sliding platform 14. The limit ring constrains the vertical state of the bottle. The identification unit 3 automatically identifies the bottle specifications and retrieves the corresponding weight parameters. After the weight sensor 4 completes the weight detection, the control system completes the qualification judgment.

[0035] The second stage is the transfer of the bottle. After determining that the beverage bottle 1 meets the requirements, the sliding platform 14 moves laterally out of the workstation along the platform slide bar 12 under the drive of the first step motor 5. The beverage bottle 1 falls vertically into the squeezing chamber because the bottom loses support, and the limiting baffle 20 accurately supports the bottom of the bottle.

[0036] The third stage is the compression process. The second stepper motor 7 pushes the sliding compression plate 21 to move towards the fixed compression plate 19. Under the action of the sliding compression plate 21 and the fixed compression plate 19, the beverage bottle 1 is flattened. During the compression process, the force sensor 8 provides real-time feedback of pressure data to ensure compression efficiency and equipment safety.

[0037] The fourth stage is the collection of finished products. The flattened beverage bottle 1 is freed from the support of the limiting baffle 20 due to deformation and falls freely from the discharge port into the collection bag 11. The counter 6 above the collection bag 11 automatically counts the number of products processed.

[0038] This invention significantly improves detection accuracy through a two-factor verification mechanism, eliminates the risk of liquid leakage with its vertical gravity conveying design, and achieves high-efficiency and energy-saving compression with its double-plate pressure extrusion structure. Compared to traditional equipment, the reduction in moving parts lowers the failure rate, and the intelligent control system ensures full automation of the processing flow. While reducing unit energy consumption, it also improves processing efficiency, making it particularly suitable for high-frequency recycling scenarios such as supermarkets and communities.

[0039] The specific embodiments of this utility model disclosed above are merely illustrative of the present utility model. These specific embodiments do not exhaustively describe all details, nor do they limit the utility model to only the described embodiments. Many modifications and variations can be made based on the content of this specification. This specification selects and specifically describes these embodiments to better explain the principles and practical applications of this utility model, thereby enabling those skilled in the art to better understand and utilize it.
