Technical Field

[0001] The present invention relates to the technical field of dry garbage bag breaking, and in particular to a dry garbage bag breaking recovery device and a control method. Background Art

[0002] As people's awareness of garbage classification increases, in daily life, people are able to classify garbage and dispose of it, which provides convenience for workers to handle garbage.

[0003] Take bagged dry garbage as an example. During the collection and treatment of dry garbage, the white pollution generated by the garbage bags cannot be ignored, so the staff need to manually open the garbage bags and classify and collect the garbage bags and garbage. This increases the workload of the staff and also affects the efficiency of dry garbage treatment. Summary of the invention

[0004] The content of the present invention is used to introduce the concepts in a brief form, which will be described in detail in the detailed implementation section below. The content of the present disclosure is not intended to identify the key features or essential features of the technical solution claimed for protection, nor is it intended to limit the scope of the technical solution claimed for protection.

[0005] Some embodiments of the present invention provide a dry garbage broken bag recovery device and a control method to solve the technical problems mentioned in the above background technology section.

[0006] In a first aspect, some embodiments of the present invention provide a dry garbage bag breaking and recycling device, comprising a device body with a delivery area on the top, a bag breaking mechanism, a transportation mechanism, a garbage storage box slidably arranged in the device body, and a garbage bag storage box arranged under the garbage receiving position of the garbage storage box, wherein:

[0007] The transport mechanism is arranged obliquely toward the garbage storage box, and is used to transport the bagged dry garbage to the garbage storage box;

[0008] The bag breaking mechanism includes a plurality of bag breaking shafts for breaking bags, a transmission assembly for driving the plurality of bag breaking shafts to extend into or out of the garbage storage box, and a plurality of scraping ring knives for scraping off garbage bag fragments wound on the bag breaking shafts;

[0009] In response to the bag breaking shaft being separated from the garbage storage box, the garbage storage box slides from the garbage receiving position to the garbage transfer position;

[0010] The plurality of bag breaking shafts pass through the scraper ring after being separated from the garbage storage box, and the garbage bag storage box receives the scraped garbage bag fragments.

[0011] In a second aspect, some embodiments of the present invention provide a control method for a dry garbage bag recovery device used in the above embodiments, the method comprising:

[0012] The bagged dry garbage placed in the delivery area is transported to the garbage collection box located at the garbage receiving position by the transportation mechanism;

[0013] The transmission assembly controls the bag breaking shaft to extend into the garbage storage box to perform bag breaking operation;

[0014] In response to completing the bag breaking operation, the transmission assembly controls the bag breaking shaft to be separated from the garbage storage box;

[0015] Control the garbage collection box to move to the garbage transfer position;

[0016] The bag breaking shaft is controlled to pass through the scraper ring knife so that the garbage bag storage box receives the garbage bag fragments.

[0017] The above-mentioned embodiments of the present invention have the following beneficial effects: through the dry garbage bag breaking and recycling device of the present invention, the garbage and the garbage bags can be collected separately while the bags are broken, which reduces the workload of the staff and improves the work efficiency of garbage collection.

[0018] Specifically, the transport mechanism can transfer bagged dry garbage to the garbage storage box at the garbage receiving position, preparing for the bag breaking operation. The transmission assembly of the bag breaking mechanism can extend the bag breaking shaft into the garbage storage box to perform the bag breaking operation. The transmission assembly can also enable the bag breaking shaft to detach from the garbage storage box after completing the bag breaking operation, and will not hinder the garbage storage box from moving to the garbage transfer position, thereby improving the safety and reliability of the device. In the process of the bag breaking shaft detaching from the garbage storage box, the bag breaking shaft can pass through the scraper ring, so that the scraper ring can scrape the garbage bag fragments wrapped around the bag breaking shaft and drop them into the garbage bag storage box. In other words, when the garbage storage box moves to the garbage transfer position and the staff collects garbage, the garbage bag storage box simultaneously collects the garbage bag fragments, thereby improving work efficiency.

[0019] In this way, the dry garbage bag breaking and recycling device realizes the automatic layered collection of garbage bags and garbage, greatly reducing the workload of staff and improving work efficiency. BRIEF DESCRIPTION OF THE DRAWINGS

For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0036] The present disclosure will be described in detail below with reference to the accompanying drawings and in conjunction with embodiments.

[0037] First see Figure 1 , Figure 1 FIG. 1 is a schematic diagram of the structure of an embodiment of a dry garbage bag breaking and recycling device of the present invention. Figure 1 As shown, the dry garbage bag breaking and recycling device includes a device body 1, a bag breaking mechanism arranged in the device body 1, a transportation mechanism, a garbage storage box 3 and a garbage bag storage box 6.

[0038] The device body 1 as the supporting structure of the device can be welded by angle steel and other profiles. The device body 1 can also be spliced ​​by plates, which is not limited here.

[0039] like Figure 1 As shown, on the right side of the top of the device body 1 ( Figure 1 A delivery area 11 is provided in the direction of the center, and the delivery area 11 is opened for delivering bagged dry garbage.

[0040] Continue reading Figure 1 The above-mentioned transport mechanism is used to transport the bagged dry garbage to the garbage storage box 3 at the garbage receiving position. It should be noted that Figure 1The position of the garbage collection box 3 shown is below the bag breaking mechanism, which is the garbage receiving position. The above-mentioned transport mechanism is arranged obliquely toward the garbage collection box 3, so that the bagged dry garbage can smoothly enter the garbage collection box 3. As an example, the above-mentioned transport mechanism can be a slide.

[0041] In an optional implementation of some embodiments, the transport mechanism includes an active roller 21, a passive roller 22, and a transmission belt 23 wound around the active roller 21 and the passive roller 22. The active roller 21 and the passive roller 22 can be pivotally connected to two roller fixing seats 24 fixed to the device body 1. One roller fixing seat 24 is installed at a high place close to the delivery area 11, and the other roller fixing seat 24 is installed at a low place close to the garbage collection box 3, so that the transmission belt 23 is arranged obliquely toward the garbage collection box 3. In the working state, the active roller 21 drives the transmission belt 23 and the passive roller 22 to rotate, thereby transporting the bagged dry garbage into the garbage collection box 3.

[0042] See also Figure 2 and Figure 3 And continue to read Figure 1 , Figure 2 It is a front view of the bag breaking mechanism of the present invention; Figure 3 FIG. 2 is a schematic diagram of the structure of the bag breaking mechanism of the present invention. Figure 1 , Figure 2 and Figure 3 As shown, the bag breaking mechanism is arranged above the garbage receiving position of the garbage storage box 3. The bag breaking mechanism may include multiple bag breaking shafts 41, a transmission assembly and multiple scraper ring knives 42. One end of the transmission assembly can be connected to the top of the device body 1, and the other end is connected to the multiple bag breaking shafts 41, thereby driving the multiple bag breaking shafts 41 to extend into or out of the garbage storage box 3. A threaded blade can be provided on each of the bag breaking shafts 41. During the bag breaking process, each bag breaking shaft 41 rotates around its own axis, thereby tearing and entangled garbage bag fragments through the threaded blade. It should be noted that although the accompanying drawings are shown with two bag breaking shafts 41 as an example, this is not the only one, and those skilled in the art can adjust the number of the bag breaking shafts 41 according to actual conditions.

[0043] In an optional implementation of some embodiments, the transmission assembly may include a transmission part and a connecting plate 43. The two ends of the transmission part connect the top of the device body 1 and the connecting plate 43. A top plate 44 may be provided on the top of the device body 1, and the transmission part is fixedly connected to the top plate 44. The transmission shaft of the transmission part may be connected to the connecting plate 43. A plurality of drive motors 411 may be installed on the connecting plate 43, and the drive shaft of each drive motor 411 passes through the connecting plate 43 and is connected to a bag breaking shaft 41. Here, the drive shaft of the drive motor 411 may be connected to the bag breaking shaft 41 via a coupling. As an example, the transmission part may be an electric push rod, an electromagnetic push rod, or the like.

[0044] The plurality of scraper rings 42 can be fixedly connected to the device body 1, so that the plurality of bag breaking shafts 41 can pass through the plurality of scraper rings 42 one by one. For example, the plurality of scraper rings 42 are connected together and fixedly connected to the device body 1 through a connecting rod.

[0045] In some optional implementations of the embodiments, the plurality of scraper rings 42 can be fixed by setting a bottom plate 45 and two optical axes 46. The bottom plate 45 can be set below the connecting plate 43, and an upper optical axis fixing seat and a lower optical axis fixing seat can be fixed on the top plate 44 and the bottom plate 45, respectively, and the two ends of the optical axis 46 are connected to the upper optical axis fixing seat and the lower optical axis fixing seat, respectively. The plurality of scraper rings 42 are fixed to the bottom of the bottom plate 45. In the assembled state, the plurality of bag breaking shafts 41 pass through the connecting plate 43 and the corresponding scraper rings 42.

[0046] The above-mentioned two optical axes 46 can also slidably pass through the connecting plate 43. Specifically, a copper sleeve can be fixed on the connecting plate 43 so that the optical axis 46 passes through the copper sleeve and is slidably connected to the copper sleeve. The above-mentioned transmission part may include a screw motor 49, a screw 47 and a screw nut 48. The above-mentioned screw nut 48 is fixedly connected to the connecting plate 43. The upper end of the screw 47 is connected to the screw motor 49 fixed to the top plate 44, and the above-mentioned screw motor 49 and the screw 47 can be connected through a coupling. The lower end of the screw 47 cooperates with the screw nut 48. In this way, in the working state, the screw 47 can drive the connecting plate 43 and the multiple bag breaking shafts 41 to reciprocate along the optical axis 46. The setting of the optical axis 46 can avoid the possibility of rotation of the connecting plate 43, thereby improving the reliability of the device.

[0047] A garbage bag identification component 51 may also be provided under the above-mentioned bottom plate 45, for detecting whether bagged dry garbage is placed in the garbage storage box 3. When bagged dry garbage is detected, the transmission part may drive the bag breaking shaft 41 to extend into the garbage storage box 3, and the driving motor 411 may drive the bag breaking shaft 41 to rotate, so that the garbage bag is wound around the bag breaking shaft 41. Then the bag breaking operation is completed. As an example, the above-mentioned garbage bag identification component 51 may include components with image acquisition functions such as a camera or an industrial camera, and an image recognition unit. Those skilled in the art may select components with image acquisition functions and image recognition units according to common knowledge.

[0048] The garbage storage box 3 is slidably arranged in the device body 1, and can be in the garbage receiving position when receiving bagged dry garbage and breaking the bag. After the bag breaking operation is completed, it moves to the garbage transfer position under the transport mechanism to facilitate the staff to collect dry garbage.

[0049] The two sides of the bottom of the garbage collection box 3 can be connected with a slider 31 respectively. The slider 31 can be connected with a ball nut. The ball nut cooperates with a ball screw 32. The ball screw 32 can be connected to the device body 1 through a ball screw fixing seat 33. One end of the ball screw 32 is also connected to a ball screw motor 34 through a coupling. After the bag breaking operation is completed, the ball screw motor 34 can drive the ball screw 32 to rotate, thereby driving the slider 31 and the garbage collection box 3 to move to the garbage transfer position.

[0050] Before the garbage collection box 3 moves to the garbage transfer position, in order to avoid the bag breaking shaft 41 from colliding with the garbage collection box, the bag breaking shaft 41 can be driven to separate from the garbage collection box 3 by the transmission part. In order to ensure that the bag breaking shaft 41 can rise to a height that is separated from the garbage collection box 3, a distance sensor 52 can be set at a position above the garbage collection box 3. The distance sensor 52 can be fixed to the device body 1. When the distance information collected by the distance sensor 52 exceeds the preset threshold, it indicates that the bag breaking shaft 41 has risen to a height higher than the distance sensor 52. As an example, the distance sensor 52 can be an infrared rangefinder, a laser rangefinder, etc., and those skilled in the art can choose according to actual conditions. The preset threshold can be determined by repeated experiments by those skilled in the art.

[0051] The transmission unit continues to drive the bag breaking shaft 41 upward, so that the bag breaking shaft 41 passes through the scraper ring 42. Figure 4 The scraper ring 42 is described. Figure 4 FIG. 4 is a schematic diagram of the structure of the scraper ring 42 of the present invention. Figure 4 and Figure 2As shown, the scraper ring 42 may include an annular body 421 and a plurality of blades 422 evenly fixed to the annular body 421. When the bag breaking shaft 41 passes through the blades 422, the garbage bag fragments wound on the bag breaking shaft 41 can be cut by the blades 422, so that the garbage bag fragments can fall into the garbage bag storage box 6 located at the lower part of the garbage receiving position of the garbage storage box 3. A slide rail fixing seat 61 may be provided at the bottom of the garbage bag storage box 6, and a slide rail 62 is provided at the bottom of the device body 1. The slide rail 62 is slidably connected to the slide rail fixing seat 61. This facilitates the extraction of the garbage bag storage box 6 to collect the garbage bag fragments.

[0052] In the above technical solution, the bag breaking shaft 41 can not only extend into the garbage storage box 3 to perform bag breaking operation, but also can be determined by the distance measuring sensor 52 when rising whether it is completely separated from the garbage storage box 3, thereby avoiding the collision between the garbage storage box 3 and the bag breaking shaft 41 when moving. When the bag breaking shaft 41 passes through the scraper ring 42, the scraper ring 42 can cut the garbage bag fragments. At this time, the garbage storage box 3 has moved to the garbage transfer position, exposing the garbage bag storage box 6 under the bag breaking shaft 41, so that the cut garbage bag fragments can smoothly enter the garbage bag storage box 6, completing the layered collection of dry garbage and garbage bag fragments.

[0053] The present application also provides a control method for a dry garbage bag recovery device, which can be used in a dry garbage bag recovery device in each of the above embodiments. Figure 5 As shown, it shows a process 500 of some embodiments of a control method of a dry garbage bag breaking and recycling device according to the present invention. The method may include the following steps:

[0054] Step 501: The bagged dry garbage placed in the delivery area is transported to a garbage storage box located at the garbage receiving position by a transportation mechanism.

[0055] First of all, it should be noted that the execution subject of the method can be a controller. The controller is connected to the transport mechanism, the bag breaking mechanism, and the garbage storage box 3. As an example, the controller can be a single chip microcomputer, a PLC, an STM32 series microcontroller, etc.

[0056] In some embodiments, the staff can manually or mechanically put the bagged dry garbage into the delivery area 11. Under the transmission of the transport mechanism, the bagged dry garbage can be transported to the garbage storage box 3 located at the garbage receiving position.

[0057] Optionally, the controller can be connected to the garbage bag identification component 51 and the active roller 21 for communication. A laser rangefinder connected to the controller for communication can be provided in the delivery area 11. When the distance information collected by the laser rangefinder changes, it indicates that bagged dry garbage has entered, and the controller receives the image information collected by the garbage bag identification component 51. If the image information shows that the bagged dry garbage has entered, the current step is completed. If the image information shows that no bagged dry garbage has entered, it indicates that the bagged garbage is stuck on the transmission belt 23. At this time, the controller controls the active roller 21 to rotate, and then the bagged dry garbage is driven by the transmission belt 23 to smoothly enter the garbage storage box 3. In this way, the transmission belt 23 is started only when it is determined through distance information and image information that the bagged dry garbage has not entered, which greatly reduces the operating power consumption of the device.

[0058] Step 502: The transmission assembly controls the bag breaking shaft to extend into the garbage storage box to perform bag breaking operations.

[0059] In some embodiments, the controller controls the transmission assembly to move the bag breaking shaft 41 downward and then extend into the garbage storage box 3. Next, the controller controls the bag breaking shaft 41 to rotate to perform the bag breaking operation.

[0060] In some optional implementations of the embodiments, the controller is in communication with the lead screw motor 49 and the drive motor 411. The controller controls the lead screw motor 49 to rotate, so that the bag breaking shaft 41 moves downward and then extends into the garbage storage box 3. Next, the controller controls the drive motor 411 to drive the bag breaking shaft 41 to rotate, thereby performing a bag breaking operation of destroying and winding the garbage bag.

[0061] Step 503 , in response to the completion of the bag breaking operation, the transmission assembly controls the bag breaking shaft 41 to separate from the garbage storage box 3 .

[0062] In some embodiments, the controller can preset the duration of the bag breaking shaft 41 rotation. The above duration represents the time of the bag breaking operation. When the bag breaking shaft 41 stops rotating, it represents the end of the bag breaking operation. The controller controls the screw motor 49 to drive the bag breaking shaft 41 to move upward until it is out of the garbage storage box 3. The controller can be connected to the distance measuring sensor 52 for communication. When the distance information collected by the distance measuring sensor 52 exceeds the preset threshold, it represents that the bag breaking shaft 41 has risen to a height higher than the distance measuring sensor 52.

[0063] Step 504, controlling the garbage collection box 3 to move to the garbage transfer position.

[0064] In some embodiments, the controller is in communication with the ball screw motor 34, and the controller controls the ball screw 32 to rotate, thereby causing the slider 31 to drive the garbage collection box 3 to move to the garbage transfer position. Next, the staff can collect the dry garbage in the garbage collection box 3.

[0065] Step 505 , controlling the bag breaking shaft 41 to pass through the scraper ring 42 , so that the garbage bag storage box 6 receives the garbage bag fragments.

[0066] In some embodiments, after the controller controls the garbage storage box 3 to move, the controller controls the lead screw motor 49 to drive the bag breaking shaft 41 to move upward until the bag breaking shaft 41 passes through the scraper ring 42, and the garbage bag fragments wrapped around the bag breaking shaft 41 can be cut by the blade 422, so that the garbage bag fragments can fall into the garbage bag storage box 6. The staff can pull out the garbage bag storage box 6 to collect the garbage bags.

[0067] Finally, the garbage bag storage box 6 and the garbage storage box 3 return to their original positions, waiting for the next bag of dry garbage to enter. Specifically, a start button can be set on the device body 1, and the start button is connected to the controller. When the start button is pressed, it indicates that the collection of dry garbage has been completed, and the controller controls the ball screw motor 34 to rotate, pulling the garbage storage box 3 back to the garbage receiving position.

[0068] The above technical solution, as an inventive point of an embodiment of the present invention, solves a new technical problem: "how to reduce the power consumption of the device". The present invention starts the transport component only when it determines that the bagged dry garbage has not entered through distance information and image information, which greatly reduces the operating power consumption of the device.

[0069] In addition, the control method can determine that the bag breaking shaft 41 is completely separated from the garbage storage box 3 through the distance measuring sensor 52, so that the garbage storage box 3 can be prevented from colliding with the bag breaking shaft 41 when moving, thereby improving the safety of the device. The descent and ascent of the bag breaking shaft 41 can respectively perform the operations of breaking the bag and scraping off the garbage bag fragments, thereby improving the versatility of the device.

[0070] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or replace some or all of the technical features therein with equivalents. However, these modifications or replacements do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present invention.
