Description

Technical Field

[0001] This invention relates to the field of environmental protection equipment technology, and in particular to an automatic garbage bag breaking machine and a method for separating garbage bags using the same. Background Technology

[0002] In the process of transporting and disposing of household waste, effectively separating the plastic bags containing the waste from the waste inside is a crucial pre-treatment step to improve the efficiency of subsequent waste sorting and resource utilization. Currently, there are various technical solutions in the industry aimed at achieving automated bag breaking, but they generally suffer from shortcomings in efficiency, adaptability, or safety.

[0003] One representative technical solution, such as the garbage bag breaker blade assembly structure and garbage bag breaker disclosed in Chinese patent CN214356851U, adopts a rotating drum structure with a bag-breaking blade belt. During operation, the user needs to hold the garbage bag and contact the rotating blade belt to achieve cutting. The main drawbacks of this solution are: firstly, when processing wet garbage with high moisture content, the bag-breaking blade belt is easily adhered to or entangled by sticky substances, causing the bag-breaking efficiency to decrease significantly over time, and it has poor adaptability to garbage bags of different thicknesses and materials; secondly, this solution poses significant safety hazards. When encountering a tough garbage bag that cannot be cut in one go, the high-speed rotating drum may pull the entire garbage bag (or even the user's arm) into the machine through the blade belt, posing a particularly high risk to elderly or child users with weaker strength.

[0004] Another type of technical solution attempts to avoid manual hand operation. For example, Chinese patent CN1035527151A discloses a garbage bag breaking machine and method, which uses a high-speed rotating drum with multiple rows of steel whips on the outer wall of the drum. The steel whips strike the freely falling garbage bags to break them. Although this solution avoids the risks of manual handling, it has the following problems: the impact of the steel whips is difficult to control precisely, and it can easily cause excessive tearing of flexible garbage bags, producing a large amount of plastic fragments mixed into the garbage, which increases the difficulty and cost of subsequent sorting. At the same time, when dealing with wet and slippery garbage bags, the drum is prone to slipping, resulting in incomplete bag breaking; for thicker bags, the opening may be insufficient, while for thinner bags, it is easy to break them into flocculent pieces, increasing the risk of internal blockage of the equipment.

[0005] In summary, existing waste bag breaking equipment either poses serious safety hazards or suffers from unsatisfactory bag breaking effects, severe fragmentation, and poor adaptability to waste bags in different states, making it difficult to achieve efficient, clean, and reliable separation of waste and plastic bags. Therefore, there is an urgent need in this field to develop an automated waste bag breaking device and method that is highly automated, has good bag breaking effects, is highly adaptable, and has excellent safety.

[0021] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0022] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0023] Example 1 Reference Figures 1 to 13 As shown, Embodiment 1 of the present invention provides an automatic garbage bag breaking machine, including a bag breaking machine platform 1, a bag breaking mechanism 2, a secondary clamping mechanism 3, a bag identification and positioning device 4, a robotic arm 5, and an electronic control component 7, among other functional components. The bag breaking machine platform 1 serves as the main frame of the equipment, used to install and support the various functional components; the bag breaking mechanism 2 is responsible for precisely cutting the garbage bags; the secondary clamping mechanism 3 is used to stably clamp the garbage bags; the bag identification and positioning device 4 realizes automatic identification and positioning of the garbage bags; the robotic arm 5 completes the grabbing and transfer of the garbage bags; and the electronic control component 7 coordinates the orderly operation of each component. These components work together to achieve a fully automated processing flow of automatic identification, precise grabbing, stable clamping, efficient bag breaking, and complete separation of garbage bags.

[0024] In one specific embodiment, such as Figures 1 to 3As shown, the bag-breaking machine 1 consists of a frame 12 and a delivery platform 11, with the delivery platform 11 mounted on the frame 12 to form a stable support structure. A delivery port 10 is located at the center of the top of the delivery platform 11 for dispensing garbage bags. A robotic arm 5 is fixedly installed on the delivery platform 11 to one side of the delivery port 10, and a bag identification and positioning device 4 is installed on the upper right side of the delivery platform 11. A bag-breaking mechanism 2 is installed on the rear side wall inside the bag-breaking machine 1, and a secondary clamping mechanism 3 is installed on the front side wall. A garbage bin 8 is placed directly below the delivery port 10 to receive the separated garbage. The electrical control component 7 is electrically connected to each actuator, and the electrical control component 7 controls the movement of the bag identification and positioning device 4, the robotic arm 5, and coordinates the bag-breaking mechanism 2 throughout the entire process.

[0025] In the above embodiments, such as Figures 4 to 9 As shown, the bag-breaking mechanism 2 includes a pushing assembly 24, a first bag-breaking knife assembly 21, a second bag-breaking knife assembly 22, and a lower bag-scraping knife assembly 23. The pushing assembly 24 is fixedly connected to the inner rear side wall of the bag-breaking machine 1 via an L-shaped support plate 244. Its support member 241 has a set of telescopic slide rails 243 at its top and bottom, which are slidably connected to the first bag-breaking knife assembly 21 and the second bag-breaking knife assembly 22, respectively. The first bag-breaking knife assembly 21 includes a left actuating element 212 and a left bag-breaking knife 211. The left actuating element 212 is fixed inside the support member 241, and its piston rod is connected to the left bag-breaking knife 211 via an L-shaped connector 25. The second bag-breaking knife assembly 22 includes a right actuating element 222 and a right bag-breaking knife 221. The right actuating element 222 is fixedly connected to the support member 241 via a Z-shaped connector 26, and its piston rod is also connected to the right bag-breaking knife 221 via an L-shaped connector 25. The lower bag scraper assembly 23 is located directly below the first bag breaking assembly 21 and the second bag breaking assembly 22. It includes a lower connector 233, a lower actuator 232 and a lower bag scraper 231. The rear end of the lower connector 233 is fixedly connected to the inner rear side wall of the bag breaking machine 1. The lower actuator 232 is fixed on the lower connector 233, and its piston rod extends forward and is fixedly connected to the lower bag scraper 231.

[0026] Furthermore, a rear actuator 242 is connected to each of the left and right sides of the back of the carrier 241. The rear actuator 242 is fixedly connected to the bag breaking machine 1 through the L-shaped support plate 244, which can enhance the overall stability of the bag breaking mechanism 2.

[0027] In the above embodiments, such as Figures 10 to 13As shown, the secondary clamping mechanism 3 includes a main clamping assembly 31 and an auxiliary clamping assembly 32. The main clamping assembly 31 includes a left connecting frame 311, a right connecting frame 312, a main actuator 313, and a main push clamp 314. The left connecting frame 311 and the right connecting frame 312 are respectively fixed to the left and right side walls inside the bag breaking machine 1. The main push clamp 314 is slidably connected to the left connecting frame 311 and the right connecting frame 312 through side-mounted slide rails 34 on both sides. The main actuator 313 is fixedly connected to the front inner side wall of the bag breaking machine 1 through a U-shaped connector 33, and its piston rod is connected to the main push clamp 314 through another U-shaped connector 33. The auxiliary clamping assembly 32 includes an auxiliary push plate 321 and an auxiliary actuator 322. The auxiliary push plate 321 is slidably connected to the left and right side walls inside the bag breaking machine 1 via side-mounted slide rails 34 on both sides. The auxiliary actuator 322 is fixedly connected to the front side wall of the bag breaking machine 1 via a U-shaped connector 33, and its piston rod is connected to the auxiliary push plate 321.

[0028] Furthermore, two limiting clamps 315 are arranged on the front side wall of the main pusher clamp 314, which can provide a more uniform clamping force distribution when clamping the garbage bag, ensuring that the garbage bag remains stable during the bag breaking process.

[0029] In the above embodiments, the bag identification and positioning device 4 employs a vision recognition module 41, which incorporates a high-precision industrial camera and image processing algorithms. The electrical control component 7 includes a PLC controller 71 and control switches 72, with each actuator electrically connected to the PLC controller 71. All actuators are electric cylinders, characterized by precise control, rapid response, and low operating noise.

[0030] Based on the above embodiments, a deodorization device 6 is further installed below the bag-breaking machine 1. Figure 1 and Figure 2 As shown, the deodorization device 6 is built-in. The deodorization device 6 is electrically connected to the PLC controller 71. After the bag is broken, it can automatically receive the start command and spray according to the preset trajectory, thereby decomposing odorous substances such as hydrogen sulfide and ammonia produced by the volatilization of organic waste in real time and effectively inhibiting the escape of harmful gases.

[0031] The working principle of the automatic garbage bag breaking machine provided in this embodiment is as follows: After the user places the garbage bag onto the bag-breaking machine 1 and starts the control switch 72, the bag identification and positioning device 4 immediately captures and positions the garbage bag. Its visual recognition module 41 takes pictures of the bag with a built-in high-precision industrial camera, and analyzes the outline, size and spatial posture of the garbage bag in real time through image processing algorithms to generate positioning coordinates and send them to the PLC controller 71.

[0032] The PLC controller 71 plans the gripping path of the robotic arm 5 based on the coordinate information, drives the gripper 51 to grab the garbage bag and move it to the disposal port 10, so that the bottom of the bag is placed on the auxiliary push plate 321. Then the controller performs adaptive attitude adjustment and triggers the action of the secondary gripping mechanism 3: the main actuator 313 pushes the main push clamp 314 forward, so that the garbage bag and the bag breaking mechanism 2 form an adaptive gripping envelope, ensuring that the main push clamp 314, the left and right bag breaking knives 221 and the lower bag scraping knife 231 work together to apply pre-tightening force.

[0033] Next, the PLC controller 71 controls the left and right actuators 222 to synchronously drive the left and right bag-breaking blades 221 to perform reciprocating sawing motions in the horizontal direction, forming a horizontal cut on the bag. Subsequently, the auxiliary actuator 322 is instructed to drive the auxiliary pusher plate 321 to move forward, causing the bottom of the garbage bag to lose support and droop under gravity, with the garbage inside falling into the garbage bin 8 below through the cut. At the same time, the lower actuator 232 drives the lower bag scraper 231 to scrape the bag back and forth, further widening the cut and guiding the bag wall to separate, allowing the garbage to be completely dumped.

[0034] To thoroughly remove residual bag debris, robotic arm 5 works by shaking the bag up and down. Once completed, robotic arm 5 moves the empty bag above the recycling bin, releases the gripper 51, and the empty bag falls into the bin.

[0035] After the bag-breaking and separation process is completed, the PLC controller 71 activates the deodorization device 6, which sprays odors onto the waste through nozzles 61 and controls all actuators to reset to their initial states. The system then enters a low-power standby mode, awaiting the next round of disposal instructions.

[0036] Example 2 like Figure 14 As shown, Embodiment 2 of the present invention provides another automatic garbage bag breaking machine. Based on Embodiment 1, Embodiment 2 replaces the visual recognition module 41 with a rangefinder 42. The rangefinder 42 is installed on the cross-section of the bag breaking machine platform 1, and its infrared coverage area 420 extends throughout the entire platform 1. The rangefinder 42 acquires real-time distance data to the surface of the garbage bag by emitting infrared or ultrasonic signals and feeds this data back to the electronic control component 7. The PLC controller 71 calculates the three-dimensional coordinates of the garbage bag based on this data and calibrates the gripping path of the robotic arm 5. This solution has a low cost and can still work stably in complex scenarios such as uneven lighting or reflective bag surfaces, which is conducive to the widespread application and promotion of automatic bag breaking machines.

[0037] The difference between Example 2 and Example 1 is that the garbage bag needs to be placed within the infrared coverage area 420 of the rangefinder 42 on the bag-breaking machine 1. The electronic control component 7 identifies the bag's outline and posture deviation based on the multi-point distance difference feedback from the rangefinder 42, and the PLC controller 71 dynamically adjusts the gripping angle and clamping force of the robotic arm 5 accordingly. Compared to the visual recognition scheme in Example 1, the rangefinder 42 scheme is slightly less accurate, but it has the advantages of rapid response and strong anti-interference capabilities, especially in complex scenarios such as uneven lighting or bag surface reflection, it can still stably output positioning parameters. The remaining working principles are the same as in Example 1 and will not be described in detail here.

[0038] Example 3 Embodiment 3 of the present invention also provides a method for separating garbage bags. This method utilizes the automatic garbage bag separating machine described in the above embodiments, and includes the following steps: S1: The garbage bag containing garbage is placed on the bag breaking machine 1. The vision recognition module 41 identifies and locates the position of the garbage bag and transmits the three-dimensional coordinate data to the PLC controller 71. The PLC controller 71 plans the grabbing path of the robotic arm 5, drives the robotic arm 5 to grab the garbage bag and move it into the delivery port 10, and places it on the auxiliary push plate 321.

[0039] S2: PLC controller 71 starts the main actuator 313, pushes the main pusher 314 forward to clamp the garbage bag, so that the bag body is tightened with the first and second bag breaking knife assemblies 22.

[0040] S3: PLC controller 71 triggers left and right actuators 222 to drive left and right bag-breaking knives 221 to reciprocate left and right, forming a horizontal cut on the garbage bag.

[0041] S4: The PLC controller 71 instructs the auxiliary execution element 322 to drive the auxiliary push plate 321 to retract, while the lower execution element 232 drives the lower scraper blade 231 to scrape forward, expanding the cut so that the garbage falls into the garbage can 8.

[0042] Specifically, after the transverse cut is formed, the PLC controller 71 immediately instructs the auxiliary actuator 322 and the lower actuator 232 to drive in tandem. The auxiliary actuator 322 drives the auxiliary push plate 321 to retract to the front of the bag breaking machine 1. The garbage bag with the transverse cut loses the support of the auxiliary push plate 321 and falls naturally under the action of gravity. The bag mouth is neatly torn along the transverse cut, and the garbage inside slides into the garbage bin 8 below. At the same time, the lower actuator 232 drives the lower scraper 231 to apply a directional scraping force to the bottom of the bag, further expanding the transverse cut and guiding the bag wall to completely separate so that the garbage inside can be completely poured into the garbage bin 8. The wet garbage inside the garbage bag is also scraped to effectively separate the wet garbage from the garbage bag and prevent it from sticking to the bag.

[0043] S5: The robotic arm 5 vibrates and moves the empty bag to the top of the recycling bin before releasing it; Specifically, the PLC controller 71 controls the robotic arm 5 to perform up-and-down shaking motions, which, together with the continuous scraping of the lower bag scraper 231, completely separates the residual bag fragments from the wet waste. Then, the robotic arm 5 moves the empty bag to the top of the recycling bin, precisely releases the gripper 51, and the empty bag falls into the bin. The entire process requires no manual intervention, the timing error of each actuator is less than 50 milliseconds, the bag breaking completion rate is as high as 99.7%, and the wet waste residue rate is less than 0.3%.

[0044] S6: PLC controller 71 triggers deodorization device 6 to spray deodorizing agent to deodorize the garbage that falls into garbage can 8.

[0045] S7: PLC controller 71 controls each actuator to reset to its initial state, waits for the next round of delivery instructions, and the system enters low-power standby mode.

[0046] This method achieves automatic identification, precise grasping, stable clamping, efficient bag breaking and complete separation of garbage bags through the collaborative work of multiple components. The entire process requires no manual intervention, with a bag breaking completion rate of up to 99.7% and a wet waste residue rate of less than 0.3%.

[0047] In another embodiment, the first bag-breaking knife assembly 21 and the second bag-breaking knife assembly 22 of the bag-breaking mechanism 2 can be replaced by a rotary cutting knife, which is driven by a motor to rotate and cut the garbage bag. The lower bag scraper assembly 23 can be a vibrating scraper, which enhances the scraping effect through high-frequency vibration.

[0048] The main clamping component 31 of the secondary clamping mechanism 3 can use a pneumatic gripper 51 instead of a pusher structure, and the clamping force can be controlled by air pressure. The auxiliary clamping component 32 can use an electromagnetic chuck to fix the bottom of the garbage bag.

[0049] In addition to visual recognition and rangefinder 42, the bag identification and positioning device 4 can also use laser scanning or 3D imaging technology to achieve higher precision positioning. The PLC controller 71 of the electrical control component 7 can be replaced with an industrial computer or other programmable controller.
