Description

Technical Field

[0001] This invention relates to the field of waste sorting and treatment technology. The invention provides a device for collecting, breaking open, and removing bags of kitchen waste and its usage method. Specifically, it relates to a device for collecting, breaking open, and removing bags of kitchen waste and its automatic processing method, which is particularly suitable for intelligent kitchen waste sorting systems in communities, residential areas, government agencies, and other scenarios. Background Technology

[0002] With the continuous acceleration of urbanization and the steady improvement of residents' living standards in my country, the amount of kitchen waste generated has shown an increasing trend year by year. How to efficiently and environmentally dispose of kitchen waste has become an urgent social problem to be solved. Kitchen waste mainly consists of easily perishable materials such as vegetable scraps, fruit peels, and leftover food. It has a high water content, is easily rotten, and has a strong odor. If it is not disposed of properly in a timely manner, it will not only affect environmental sanitation but also easily breed mosquitoes and flies, endangering human health.

[0003] The standard process for sorting and processing kitchen waste typically includes key steps such as "resident disposal—bag breaking—sorting—resource conversion." Especially in the bag breaking and removal stage, since kitchen waste is mostly packaged in plastic bags, the bags must be broken open and the plastic bags separated for recycling in order to achieve composting or resource recovery. Currently, many residents lack acceptance of the bag breaking process and generally throw the waste directly into the bags without sorting, leading to low efficiency in subsequent resource processing.

[0004] In existing technologies, some waste disposal equipment attempts to introduce bag-breaking mechanisms to assist residents in disposing of kitchen waste, but there are still many shortcomings. For example: (1) Some devices use serrated barbs installed on the edge of the garbage can, requiring residents to manually press and pull the garbage bag to break it. Such devices are simple in structure and low in cost, but they can only break the side of the bag, and the residue is easy to remain at the bottom of the bag, which cannot completely release the kitchen waste. Moreover, the whole process depends on manual operation and lacks automated control.

[0005] (2) Some devices propose to use infrared triggering to control the blade to cut open the bottom of the bag. Although this achieves non-contact automatic bag breaking, there is a risk of the bag clamping and bag transfer structure falling off.

[0006] In summary, existing kitchen waste treatment devices suffer from technical bottlenecks such as functional fragmentation in bag breaking and removal, low automation, and low processing efficiency, making it difficult to meet residents' dual needs for convenient disposal and intelligent sorting. Summary of the Invention

[0007] The purpose of this invention is to address the shortcomings of existing technologies by proposing an integrated device and method for collecting, sorting, and breaking bags of kitchen waste. Through structural optimization and process linkage, the invention achieves fully automated control from waste disposal to sorted output, effectively improving processing efficiency and environmental protection.

[0008] To achieve the above objectives, the present invention adopts the following technical solution: This invention discloses a device for collecting, breaking open, and removing bags of kitchen waste, comprising: The main frame is a rigid box structure with internal partitioned support structures to support and integrate the following functional units: The collection device is used to receive kitchen waste bags disposed of by residents, and it can extend and retract inside and outside the waste disposal port of the main frame. The bag clamping device is used to assist in the clamping of food waste bags and the transfer and sorting collection. The bag-breaking device is used to break open the bags of kitchen waste and separate them from the kitchen waste. The waste disposal opening / closing device is used to open and close the waste disposal opening; The food waste bin is located below the collection device inside the main frame and is used to receive food waste that falls out after the food waste bag is torn. Other waste bins, located on the side of the food waste bins, are used to receive food waste bags transferred by the bag clamping device; A disinfection device is used to disinfect the kitchen waste bin regularly or in real time to maintain internal hygiene.

[0009] As a further preferred embodiment, the collection device is installed inside the main frame, including a telescopic mechanism fixed inside the main frame. A collection bin is fixed on the telescopic end of the telescopic mechanism. The collection bin can move in and out of the garbage disposal opening of the main frame. The bottom of the collection bin is a pair of openable and closable bottom covers. The pair of bottom covers are respectively hinged to a set of opposite bottom edges of the collection bin.

[0010] As a further preferred embodiment, the bottom of the collection bucket is equipped with a bottom opening and closing device, which includes a direct-acting bidirectional electric push rod. Each end of the direct-acting bidirectional electric push rod has a telescopic push rod, and each telescopic push rod corresponds to a bottom cover plate of the collection bucket. The end of the telescopic push rod is a slider that pushes the bottom cover plate of the collection bucket to close. A magnetic switch is installed on the direct-acting bidirectional electric push rod to detect the extension and retraction and determine the stroke length.

[0011] As a further preferred embodiment, the bag clamping device includes a translation mechanism, a lifting mechanism, and a roller gripper device. The translation mechanism is installed inside the main frame, the lifting mechanism is located on the horizontal telescopic component of the translation mechanism, and the roller gripper device is located on the longitudinal telescopic component of the lifting mechanism. Driven by the translation mechanism and the lifting mechanism, the roller gripper device clamps the kitchen waste bag from the collection device and transfers it to other garbage bins. The translation mechanism and the lifting mechanism are equipped with magnetic switches to detect the extension and retraction limits and determine the stroke length and position.

[0012] As a further preferred embodiment, the roller gripper device includes a roller electric push rod, a mounting frame, a first roller, and a second roller. The mounting frame is fixed to the longitudinal telescopic component of the lifting mechanism. The mounting frame has a pair of rotating rods with limited rotation. The first roller and the second roller are respectively fixed on a rotating rod and are parallel to each other. The roller electric push rod is fixed to the mounting frame at the end of the pair of rotating rods. The push rod part of the roller electric push rod is longitudinally telescopic, and the end of the push rod part is also provided with a horizontal slot transmission device. Each end of the pair of rotating rods is provided with a rotating pin. One end of the rotating pin is fixed to the end of the rotating rod, and the other end is placed in the slot of the slot transmission device through the pin. The roller electric push rod drives the slot transmission device to move up and down by driving the push rod part, thereby driving the rotating pin to swing up and down, realizing the opposite rotation of the first roller and the second roller.

[0013] As a further preferred embodiment, the surfaces of the first roller and the second roller are distributed with barbs, and there is a gap between the first roller and the second roller.

[0014] As a further preferred embodiment, the bag-breaking device includes a bag-breaking blade and a bag-breaking power transmission device. The bag-breaking blade is mounted on the bag-breaking power transmission device, which is fixed within the main frame. The bag-breaking blade is located on the moving path of the collection bucket. When the bottom of the collection bucket is closed, a gap is formed between a pair of bottom cover plates of the collection bucket for the bag-breaking blade to be inserted from the bottom surface. The side of the collection bucket connected to this gap also has a gap for insertion from the side.

[0015] As a further preferred option, the collection bin is equipped with a waste disposal detection sensor to monitor in real time whether kitchen waste has been put in.

[0016] As a further preferred option, a ventilation device is also provided on the main frame.

[0017] A method for using a device for collecting, breaking open, and removing bags for kitchen waste disposal according to the present invention includes the following steps: S1: In the initial state, the collection bin of the collection device is located outside the disposal port and is in an extended waiting state. The inside of the collection bin is equipped with a waste disposal detection sensor to monitor in real time whether kitchen waste is being disposed of. S2: The telescopic mechanism of the collection device is equipped with a position sensor to determine the extension and retraction positions. When the garbage disposal detection sensor detects that there is garbage in the collection bin, the disposal collection device retracts to above the bag breaking device, and the bag breaking blade is inserted into the gap at the bottom of the collection bin. S3: The telescopic mechanism of the collection device retracts, and the lifting mechanism in the bag clamping device is activated, driving the roller gripper device to descend vertically. The roller gripper device is equipped with a laser displacement sensor to accurately measure the distance between the gripper and the bag surface, used for final landing / clamping position control. After accurately determining the gripping height using the displacement sensor, the roller gripper device performs a rotating gripping action to clamp the garbage bag. The roller gripper device is equipped with multi-point distributed pressure-sensitive sensors to measure the force on the gripper contact surface, used to detect whether the gripping is successful. S4: After the bag clamping action is completed, the bag-breaking blade set at the bottom of the collection bin starts to rotate, cutting and breaking the garbage bag, causing damage to the bag structure; S5: After the bag is broken, the bottom cover of the collection bin is flipped open to form a discharge port. The kitchen waste falls quickly into the kitchen waste bin below under the action of gravity, realizing the separation of the bag material and the kitchen waste. S6: After the bag clamping device completes the falling operation of kitchen waste, it enters the rising and translating stage. The lifting mechanism and translating mechanism drive the roller clamping device to translate it to above other garbage bins and release the clamped garbage bag into other garbage bins. The magnetic switches installed on the translating mechanism and lifting mechanism determine the translation and lifting positions. S7: After the bag clamping device completes the release action, it automatically resets to the initial position; the collection and disposal device extends out of the disposal port again, ready for the next waste disposal cycle; S8: The food waste bin is equipped with a row of proximity sensors to detect the height of food waste. When the detected amount of food waste in the food waste bin exceeds 90% of its total capacity, the capacity sensor will transmit an alarm signal to the control system. The system will issue a warning and prohibit the opening of the disposal door to prevent the waste from overflowing.

[0018] The invention features an integrated box design that incorporates a telescopic collection and dispensing mechanism, a rotating bag-breaking component, a bag-clamping system, and a multi-level sensor detection module. This, combined with a control system, enables closed-loop control of the entire process, effectively achieving automatic separation and sorting of kitchen waste and plastic bags, thereby improving overall processing efficiency and environmental hygiene.

Detailed Implementation

[0020] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0021] like Figure 1 This invention provides an integrated device for collecting, breaking, and removing bags of kitchen waste. The main functional modules include an integrated box structure, a main frame bag clamping device 2, a collection and dispensing device 3, a bottom opening and closing device for the collection bin 4, a bag breaking device 5, a dispensing opening opening and closing device 6, a disinfection device 7, a ventilation device 8, a kitchen waste bin 9, and an external other waste bin 10.

[0022] like Figure 2 The structure adopts a partitioned modular design. The integrated box structure includes a main frame 1, and each functional module is arranged in the main frame 1. The main frame 1 includes other waste guide plate 11, disposal port 12, rear box cover 13, bag breaking device installation location 14, bag clamping device installation location 15, ventilation device installation location 16, disposal and collection device installation location 17, and kitchen waste bin placement location 18. The equipment operates as follows: like Figure 3 The collection device 3 is a retractable structure, comprising a telescopic mechanism 31, a collection bin 32, and a bottom opening / closing device 4 for the collection bin. In its initial state, the collection bin 32 of the collection device 3 is located outside the disposal opening 12, in an extended, ready-to-go state. Residents can place garbage bags containing kitchen waste into the collection bin 32. The collection bin 32 is equipped with a sensor, specifically a garbage disposal detection sensor, to monitor in real time whether kitchen waste has been disposed of. When the garbage disposal detection sensor detects garbage in the collection bin 32, the telescopic mechanism 31 controls the entire collection device to retract into the garbage container.

[0023] like Figure 4 The dispensing port 12 is equipped with a dispensing port opening and closing device 6. The dispensing port opening and closing device 6 adopts a longitudinal retraction drive method and includes a dispensing door 62 located at the dispensing port and a door opening and closing actuator 61 connected to the drive. The door opening and closing actuator 61 is vertically connected to the back of the dispensing door 62 and drives the dispensing door 62 to open and close in the vertical direction.

[0024] The disposal port opening and closing device 6 saves space and the opening and closing of the door does not affect the subsequent work process. The disposal door opening and closing actuator 61 drives the disposal door 62 to achieve automatic closing, so as to avoid external interference to the waste disposal process.

[0025] like Figure 5 The bag-clamping device includes a translation mechanism 21, a lifting mechanism 22, and a roller gripper device 23. The translation mechanism 21 is mounted on the transverse guide rail of the main frame of the device and is used to drive the bag-clamping device to move horizontally between the bag-breaking area and the waste sorting area. The lifting mechanism 22 is vertically mounted on the translation mechanism 21 and is used to drive the roller gripper device 23 to move up and down in the vertical direction. The roller gripper device 23 includes a pair of self-adaptive rotating rollers with motor-driven clamping and releasing functions, used to accurately clamp garbage bags of different shapes and sizes. The roller drive device employs vertical conveying technology and mainly consists of two parts: barbed rollers and conveying actuators. The barbed rollers, acting as the garbage bag gripping device, are primarily composed of a first roller 231, a second roller 232, and protruding barbs 233. The protruding barbs 233 increase the friction against the garbage bag, thereby easily squeezing and gripping it. The conveying actuators include a roller electric push rod 235, a rotating rod 236, a rotating pin 237, and a slotted transmission device 238. The barbed rollers serve as a garbage bag gripping device, primarily consisting of a first roller 231, a second roller 232, and protruding barbs 233. The protruding barbs 233 increase the friction against the garbage bag, thereby easily squeezing and gripping it for sorting. The conveying actuators include a roller electric push rod 235, a slotted transmission device 238, and a rotating pin 237.

[0026] The roller gripper device 23 is equipped with a position sensor and a gripping force detection unit. When the lifting mechanism 22 descends to the preset height area, the position sensor detects the position of the garbage bag in real time and automatically adjusts the gripper closure to achieve non-destructive gripping of the flexible garbage bag.

[0027] After the collection device retracts into place and the delivery door 62 is completely closed, the lifting mechanism 22 in the bag clamping device is activated, driving the roller gripper device 23 to descend vertically, and the clamping height is accurately determined by the position sensor.

[0028] After the garbage bag is gripped, the lifting mechanism 22 rises to the initial height, and the translation mechanism 21 moves the bag gripping device 2 to above the other garbage guide plate 11 located in the main frame 1 structure. After receiving the release command, the roller gripper device 23 automatically releases the garbage bag, allowing it to slide along the guide plate into the preset other garbage disposal container under the action of gravity.

[0029] like Figure 6 As shown, the vertical movement of the electric roller push rod 235, via the slotted transmission device 238, is converted into a 90-degree rotational movement of the barbed rollers through the rotating rod 236 and the rotating pin 237. The upward movement of the electric roller push rod 235 is converted into the first roller 231 rotating counterclockwise and the second roller 232 rotating clockwise, thereby achieving a squeezing and gripping method to clamp the garbage bag, and vice versa for releasing it.

[0030] The bag-breaking mechanism includes a bag-breaking blade 51 and a power transmission device 52. The power transmission device 52 uses a DC motor to drive the transmission gear to provide power to the bag-breaking saw blade.

[0031] like Figure 7As shown, the bag-breaking mechanism includes a bag-breaking blade 51 and a bag-breaking power transmission device 52. The bag-breaking power transmission device 52 uses a DC motor to drive the transmission gear to provide power to the bag-breaking saw blade. The bag-breaking blade 51 adopts a Reuleaux triangle structure, which avoids the obstruction of the gripping rollers from the circular saw blade's high center and low sides. The rotation trajectory of the Reuleaux triangle structure is a square, which can effectively break the garbage bag at the same height, avoiding collision with the roller grippers and causing equipment collisions and safety issues. The bottom cover plate 41 of the collection bin adopts a slotted structure in the middle, and the bag-breaking device 5 can break the bag from the slot. After the bag clamping action is completed, the bag-breaking rotating blade set at the bottom of the collection bin 32 starts to rotate, cutting and breaking the garbage bag, causing damage to the bag structure.

[0032] like Figure 8 As shown, the bottom cover 41 of the collection bin includes a pair of split-opening flip-top structures, which are respectively installed on both sides of the bottom edge of the collection bin via hinge shafts. After the garbage bag is torn, the bottom cover 41 of the collection bin automatically opens, allowing the kitchen waste to fall into the kitchen waste bin 9. The bottom cover 41 of the collection bin is driven to open and close by a direct-acting bidirectional electric push rod 42. After the bag is broken, the control system controls the double bottom plates at the bottom of the collection bin 32 to flip open, forming a discharge port. Under the action of gravity, the kitchen waste quickly falls into the kitchen waste bin 9 below or into the pre-treatment system, realizing the separation of bagged material and kitchen waste.

[0033] The control system is equipped with jamming detection logic. When the continuous running time of the drive device exceeds the preset upper limit and the position of the cover plate does not change, the system will trigger the protection mechanism to prevent the direct-acting bidirectional electric push rod 42 or the drive motor from being overloaded and damaged.

[0034] After the bag clamping device completes the falling operation of kitchen waste, it enters the rising and translating stage. The lifting mechanism 22 and the translating mechanism 21 drive the drive roller clamping device 23 to translate to the position above the garbage guide plate. The slot transmission device 238 converts the downward movement of the roller electric push rod 235 into a 90-degree rotational movement of the barbed roller. The first roller 231 rotates clockwise and the second roller 232 rotates counterclockwise, thereby realizing the release action and releasing the clamped garbage bag into other garbage guide channels for easy entry into the special recycling bin for plastic bags.

[0035] After the bag clamping device completes its release action, it automatically resets to its initial position; the control system controls the electric push rod 235 of the roller to open the disposal door, and the disposal and collection device 3 extends out of the disposal opening again, ready for the next waste disposal cycle.

[0036] The processing method also includes a waste volume detection step. When the amount of kitchen waste in the kitchen waste bin 9 exceeds 90% of its total capacity, the capacity sensor will transmit an alarm signal to the control system. The system will issue a warning and prohibit the opening of the disposal door to prevent waste from overflowing.

[0037] The present invention provides a method for using an integrated device for collecting, breaking open, and removing bags of kitchen waste, comprising the following steps: S1: In the initial state, the collection bin 32 of the collection device 3 is located outside the disposal port 12 and is in an extended, waiting state. The collection bin 32 is equipped with a waste disposal detection sensor to monitor in real time whether kitchen waste has been disposed of.

[0038] S2: When the waste disposal detection sensor detects waste in the collection bin 32, the disposal and collection device 3 retracts above the bag-breaking device 5, and the bag-breaking blade 51 inserts into the groove at the bottom of the collection bin. At the same time, the disposal door 61 is closed by the door opening and closing actuator 61 to avoid external interference to the waste disposal process.

[0039] S4: After the telescopic mechanism 31 of the collection device 3 is retracted into place and the collection door 61 is completely closed, the lifting mechanism 22 in the bag clamping device 2 is activated, driving the roller gripper device 23 to descend vertically. After accurately determining the clamping height by the position sensor, the roller gripper device 23 performs a rotating gripping action to clamp the garbage bag.

[0040] S3: After the bag clamping action is completed, the bag-breaking blade 51 set at the bottom of the collection bin 32 starts to rotate, cutting and breaking the garbage bag, causing damage to the bag structure.

[0041] S5: After the bag is broken, the bottom plates on both sides of the bottom cover 41 of the collection bin are flipped open to form a discharge port. The kitchen waste falls quickly into the kitchen waste bin below or the pre-treatment system under the action of gravity, realizing the separation of the bag material and the kitchen waste.

[0042] S6: After the bag clamping device 2 completes the falling operation of kitchen waste, it enters the rising and translating stage. The lifting mechanism 22 and the translating mechanism 21 drive the roller clamping device 23 to move to the position above the garbage guide plate and release the clamped garbage bag into other garbage guide channels for easy entry into the special recycling bin for plastic bags.

[0043] S7: After the bag clamping device 2 completes the release action, it automatically resets to the initial position; the door opening and closing actuator 61 opens the disposal door 62, and the disposal and collection device 3 extends out of the disposal opening again, ready for the next waste disposal cycle.

[0044] S8: The processing method also includes a waste capacity detection step. When the amount of kitchen waste in the kitchen waste bin 9 exceeds 90% of its total capacity, the capacity sensor will transmit an alarm signal to the control system. The system will issue a warning and prohibit the opening of the disposal door to prevent waste from overflowing.

[0045] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.

The roller clamping jaw device (23) is provided with a laser displacement sensor, which accurately measures the distance from the clamp to the bag surface, and is used for final landing / compaction position control. After accurately determining the clamping height by the displacement sensor, the roller clamping jaw device (23) performs a rotating grabbing action to clamp the garbage bag. The roller clamping jaw device (23) is provided with a multi-point distributed pressure sensor to measure the force on the clamping jaw contact surface, which is used to detect whether the clamping is successful; S4: After the bag clamping action is completed, the bag breaking blade (51) provided at the bottom of the collection barrel (32) starts to rotate to cut and break the garbage bag, so that the bag structure is damaged; S5: After the bag breaking is completed, the flip opening of the collection barrel bottom cover (41) is opened to form a discharge port, and the kitchen waste falls into the kitchen waste barrel (9) below under the action of gravity, realizing the separation of the bag and the kitchen waste; S6: After the bag clamping device (2) completes the kitchen waste falling operation, it enters the lifting and translation stage, and the roller clamping jaw device (23) is driven by the lifting mechanism (22) and the translation mechanism (21) to translate to above the other garbage can (10), and the clamped garbage bag is released to the other garbage can (10). The magnetic switch installed on the translation mechanism (21) and the lifting mechanism (22) determines the position of translation and lifting; S7: After the bag clamping device (2) completes the release action, it is automatically reset to the initial position; the throwing and collecting device (3) is retracted to the outside of the throwing port, preparing for the next garbage throwing cycle; S8: The kitchen waste barrel (9) is provided with a proximity sensor array for detecting the height of the kitchen waste. When the detected amount of kitchen waste in the kitchen waste barrel (9) exceeds 90% of its total capacity, the capacity sensor will send an alarm signal to the control system, and the system will issue a warning and prohibit the opening of the throwing door to prevent garbage overflow.
