Description

Technical Field

[0001] The invention relates to a mechanical device, in particular to a bag breaking device for bagged domestic garbage, specifically to a bag breaking device for domestic garbage that is compatible with a community intelligent garbage bin. Background Art

[0002] The classification, recycling and resource utilization of domestic waste is not only an important means to achieve the resource reuse of urban solid waste, but also an important measure to save energy and reduce emissions.

[0003] In foreign countries where the classification and recycling of domestic waste was implemented earlier, such as Germany, the food waste in the domestic waste is directly discharged into the underground pipe network through a special pipeline and then connected to the food waste biomass treatment enterprise, while other domestic waste is packed in different colored garbage bags according to categories and concentrated at a fixed time and place, and then transported to the corresponding treatment point for treatment by a dedicated person. The implementation of the classification and recycling of domestic waste in my country was relatively late, but the starting point was high. In cities such as Hangzhou, which are leading in the implementation of the classification and recycling of domestic waste, many smart garbage classification and recycling bins are put in the main sources of domestic waste, such as residential communities, according to the number of residents in the community and the characteristics of the population. These smart garbage classification and recycling bins can be roughly divided into two categories: bagless recycling and ordinary recycling. Among them, the bagless recycling type requires residents to pour domestic waste out of garbage bags and put it into the delivery port when putting out garbage; while the ordinary recycling type allows bagged garbage to be directly put into the delivery port. When using bagless recycling smart garbage sorting and recycling bins, when residents pour domestic garbage from garbage bags and put them into the disposal port, it is inevitable that the "wet garbage" in the domestic garbage will cause a large proportion of kitchen waste in the domestic garbage, causing contamination of the disposal port and splashing of soup and residues, as well as odors if not cleaned in time. In addition, special personnel are required to supervise whether garbage bags are mixed in, etc. Therefore, the actual utilization rate of this type of smart garbage sorting and recycling bin is very low. As for the ordinary recycling type intelligent garbage classification recycling bin, although it avoids the aforementioned problems of bagless recycling type, a large number of garbage bags enter the recycling bin, which not only reduces the effective volume of the garbage recycling bin, but also greatly increases the workload of subsequent transportation and bag removal. More importantly, community residents have long formed the habit of putting household garbage in plastic bags of various unknown sources (mostly non-degradable plastic products), which makes it necessary to add the bag removal link in the subsequent treatment of household garbage. However, the workload of bag removal is huge, the efficiency is low, and household garbage is very easy to rot, which is harmful to the disposal personnel. At the same time, due to the particularity of household garbage, it is difficult to realize resource utilization such as fuel and fertilizer, so most of the household garbage has to be "landfilled". To a certain extent, bagged household garbage has become an important source of "plastic pollution" that causes great harm at this stage. It can be seen that it is urgent to develop a bag breaking device for bagged household garbage that is compatible with community intelligent garbage classification recycling bins, so as to promote the in-depth and practical use of community intelligent garbage classification recycling bins, and then promote the classification and recycling of household garbage through equipment upgrades.

[0004] According to the generation, composition and placement habits of domestic waste of community residents and the functional characteristics of intelligent waste classification and recycling bins, there are several technical difficulties in the bagged domestic waste breaking device adapted to the community intelligent waste classification and recycling bin. First, the sizes and specifications of garbage bags for domestic waste are diverse and the holding capacity is different, resulting in different shapes, volumes and sizes of bagged domestic waste. Therefore, the bagged domestic waste breaking device adapted to the community intelligent waste classification and recycling bin needs to be able to adapt to different sizes of bagged domestic waste. Second, when breaking bags of bagged domestic waste, it is necessary to avoid or minimize the generation of plastic fragments as much as possible, and the garbage bags can be stored independently and temporarily after breaking for subsequent resource recycling and treatment. This is conducive to reducing the possibility of plastic bags with perishable substances attached to enter the classification garbage bin and contaminate resource-usable domestic waste such as cardboard that can be directly recycled, kitchen waste that can be used as feed fertilizer, etc., and also reduces the risk of "plastic pollution" in bagged domestic waste. Third, bagged domestic waste itself is a flexible body. How to avoid the fragmentation of garbage bags while breaking them efficiently and reliably is also a technical problem that needs to be solved. In addition, after the bag of bagged domestic garbage is broken, how to separate the garbage in the bag from the garbage bag as completely as possible is also one of the technical difficulties that need to be considered.

[0005] However, existing domestic waste bag breaking devices are mostly only for large-scale centralized garbage treatment sites (stations), and are not suitable for single-time small but high-frequency community domestic waste delivery. In addition, they often break bagged domestic waste and garbage bags (mostly plastic bags) together, making it difficult to separate the plastic garbage bags from them later.

[0006] For example, the invention patent with application number 202210687974.6 discloses a bag breaking mechanism with an arc-shaped clamp, a garbage station and a bag breaking method, which can clamp garbage bags of different sizes by using the arc-shaped clamp, and use the guide rail assembly to move the clamped garbage bags into the collection box for crushing. This patent has good adaptability to bagged garbage that is tightened in a standardized manner and has a clear tightening head, that is, bagged garbage that is clamped from one end by the arc-shaped clamp. However, in fact, there are many different tightening conditions for bagged domestic garbage, and the position after delivery cannot ensure that the tightening head is facing upward. Moreover, if the bagged garbage is clamped from the waist, it is inevitable that domestic garbage with extremely high water content will be squeezed out of the garbage bag, causing it to overflow when clamping the bagged garbage. This is not a problem for large-scale domestic garbage centralized treatment stations, but it is obviously not suitable for adapting to community smart garbage sorting and recycling bins, and it will inevitably pollute the delivery port, causing the smart garbage sorting and recycling bins to be as dirty and messy as ordinary garbage cans. Meanwhile, the bag breaking mechanism described in the invention adopts integral crushing, that is, the plastic garbage bags and domestic garbage are still mixed together after the bags are broken, and it does not have the function of separating the plastic garbage bags from domestic garbage.

[0007] For another example, the invention patent with application number 201710025303.2, in order to solve the problem that the existence of disposable tableware and plastic bags in food waste will cause the subsequent processing equipment to be entangled and blocked seriously, causing equipment damage, etc., invented a bag breaking machine and food waste treatment equipment containing a bag breaking machine. After the food waste material enters the S-shaped feeding channel, it passes through the first bag breaking device, the second bag breaking device and the third bag breaking device in sequence. After the bag-like objects in the material are broken twice by the moving cutter discs of the first bag breaking device and the second bag breaking device, most of the interference of the bag-like objects has been eliminated. After further breaking by the third bag breaking device, the bag-like objects in the material can be fully broken. This invention is aimed at food waste biomass utilization enterprises and solves the problem that the bag-like objects in food waste will cause damage to the subsequent processing equipment by winding, etc., and its effect is still to break the whole and then sort it. Obviously, it is not suitable for breaking bags of community bagged domestic waste with a wide variety of types and a high frequency of single small quantities, and it also crushes plastic garbage bags and other domestic waste as a whole.

[0008] For example, the invention patent with application number 201310112513.7 (bag breaking equipment and garbage sorting system) describes a bag breaking device that breaks bags by whipping with flexible parts, thus avoiding entanglement and reducing wear. The bag-like objects will not be pulled into strips or broken open excessively, thereby reducing energy consumption and improving bag breaking efficiency. However, it still crushes the bagged domestic garbage as a whole, i.e., it does not have the function of separating garbage bags (mostly non-degradable plastic products).

[0009] At present, there are some bag breaking devices that can separate garbage bags during the bag breaking process or facilitate the subsequent sorting of garbage bags, but generally there are problems such as poor bag breaking effect, low efficiency, high energy consumption and large space occupation.

[0010] For example, the invention patent with application number 201810783944.9 discloses a garbage bag opening machine and a garbage cleaning and bag opening machine. The garbage bag opening machine described in the patent utilizes the "knocking" of multiple blades on the rotating shaft of the rotary mechanism and the "impact" of the protrusions in the shell of the bag opening mechanism to shake out and break up the garbage in the garbage bag. It is more suitable for bagged garbage with loose bag openings, but it is not effective and efficient for bagged garbage with tightly tied bag openings, or even fails to open the bag.

[0011] For another example, the invention patent with application number 202410002835.4 discloses an automatic bag breaking, classification, collection and recycling device for kitchen waste. By setting up a primary bag breaking area and a secondary bag breaking area, it can realize the automatic bag breaking of multiple small plastic bags in a large bag. The primary bag breaking area uses two triangular reciprocating knives to insert the garbage bag for the large bag and then relies on the toothed reciprocating knife to break the bag. On the one hand, the patent is also applicable to food waste biomass utilization enterprises; on the other hand, as mentioned above, bagged domestic garbage is essentially a flexible body, which will inevitably give way and deform once it is subjected to force. Whether the triangular reciprocating knife used in the primary bag breaking area of ​​the patent can be effectively inserted into the garbage bag and whether the toothed reciprocating knife can effectively break the bag is worth discussing. In addition, after breaking the bag, relying solely on the weight of the garbage to separate from the garbage bag will inevitably cause the extracted garbage bag to adhere to a lot of residual garbage.

[0012] From the above, it can be seen that there are many solutions for breaking bags of bagged domestic waste, which shows that this problem is an important problem that restricts the classification and resource utilization of domestic waste; however, the existing solutions either break the bagged waste as a whole, which does not need to solve the problem of fixing the flexible bagged domestic waste, but will make it extremely difficult to separate the garbage bags (mostly non-degradable plastic products) from the classified garbage in the future, resulting in many obstacles to resource utilization; or they can be separated or facilitate the subsequent sorting of garbage bags, but there are problems such as poor bag breaking effect and low efficiency, and they are not compatible with smart garbage classification and recycling bins. Therefore, it can be said that it is precisely because of the lack of bag breaking devices for bagged domestic waste that are compatible with community smart garbage classification and recycling bins that residents are unwilling to use community smart garbage classification and recycling bins at this stage, and they have become "decorations". To a certain extent, it also restricts the in-depth and effective implementation of garbage classification and recycling resource utilization. Summary of the invention

The rear end of the transmission shaft 10-4 and both ends of the driven shaft 10-5 are sleeved with sleeves 10-7. The sleeves 10-7 are fixed to the frame 1 by bolts. The conveyor belt 10-6 is sleeved on the transmission shaft 10-4 and the driven shaft 10-5.

[0044] like Figure 7 , Figure 4 The horizontal screw assembly 14 is composed of a screw motor 14-1, a transmission screw 14-2, a transmission nut 14-3, a nut seat 14-4, a motor bracket 14-5, and a bearing seat 14-6. The screw motor 14-1 is directly connected to the transmission screw 14-2 and is fixedly installed on the frame 1 through the motor bracket 14-5. The nut seat 14-4 is sleeved on the transmission nut 14-3 and is connected to the transmission nut 14-3 as a whole through bolts ( Figure 4 ), the transmission nut 14-3 is sleeved on the transmission screw 14-2, and the nut seat 14-4 is connected to the fixed seat 8-2 of the vertical screw assembly 8 (there is a protrusion on it and the connection part is located next to the screw motor 8-1) by bolts. The horizontal light bar follower assembly 15 is composed of a bearing seat 15-1, a light rod 15-2, and a square sleeve 15-3. There are two bearing seats 15-1, which are respectively connected to the two ends of the light rod 15-2 and fixed to the frame 1 by bolts. The square sleeve 15-3 is connected to the vertical light bar follower assembly 16 by bolts. In specific implementation, the anti-rotation structure of the nut seat 14-4 can also be implemented by conventional design. In specific implementation, the anti-rotation of the nut seat 14-4 can be implemented by conventional design, so that the nut seat 14-4 has a guide block, and a matching guide groove is designed in the frame 1. The guide block moves along the guide groove, thereby preventing the nut seat 14-4 from rotating synchronously with the nut 14-3.

[0045] Combination Figure 7 ,like Figure 8 The vertical light bar follower assembly 16 comprises: a left half bearing seat 16-1, a right half bearing seat 16-2, a bearing seat connecting screw 16-3, a vertical light bar 16-4, a square sleeve 16-5 and a support seat 16-6 ( Figure 5 ), the left half bearing seat 16-1 and the right half bearing seat 16-2 are connected into one by the bearing seat connecting screw 16-3, connected to the horizontal light bar follower assembly 15 through the connecting part of the left half bearing seat 16-1, and connected to the other end of the cross beam 3 through the square sleeve 16-5 with the help of the connecting piece 2.

[0046] like Figure 5 A gravity sensor 5 is installed below the front and rear ends of the cross beam 3, and the lower ends of the sensors 5 are connected to the two ends of the straight beam 4, respectively. A pair of manipulators 6 are invertedly installed below the straight beam 4 through a manipulator connector 17.

[0047] The working process of the present invention is: The bagged domestic garbage falls from the delivery port onto the bottom plate 7-1-1. After the system recognizes the garbage, the horizontal screw assembly 14 and the horizontal light bar follower assembly 15 start working. The screw motor 14-1 drives the transmission screw 14-2 to rotate, and the transmission screw 14-2 rotates to drive the transmission nut 14-3 and the nut seat 14-4 to move horizontally, and the nut seat 14-4 drives the vertical screw mechanism 8 connected thereto to move horizontally, and the square sleeve 15-3 drives the vertical light bar follower assembly 16 connected thereto to move horizontally; at the same time, the screw motor 8-1 of the vertical screw mechanism drives the transmission nut 8-4 and the nut seat 8-5 to move in the vertical direction, so that the cross beam 3 connected to the nut seat 8-5 of the vertical screw mechanism moves in the vertical direction, thereby controlling the manipulator 6 invertedly installed under the straight beam 5 to move to a position suitable for grabbing the bagged garbage. In specific implementation, the position limitation of the nut seat 8-5 between the two reinforcing rods 8-7 can be achieved by a clamp or an axial groove, so that the nut seat 8-5 can only move linearly between the two reinforcing rods 8-7 and cannot rotate with the nut 8-4. In specific implementation, the anti-rotation technology of the nut seat can also be implemented by conventional design.

[0048] The servo inside the manipulator 6 controls the claw to rotate to a suitable grasping angle and grasp the bagged garbage. Then, the screw motor 8-1 of the vertical screw assembly 8 controls the nut seat 8-5 to move upward to make the bagged domestic garbage suspended in the air, and the gravity sensor 5 weighs the bagged domestic garbage. Then, the screw motor 8-5 controls the nut seat 8-5 to move downward again to make the bagged domestic garbage close to the serrated bag-breaking blade 7-3. The serrated bag-breaking blade 7-3 has a pair of blades, which rely on the gap between them to limit the longitudinal swing of the bagged garbage.

[0049] The motor 7-1-3 of the bag breaking assembly drives the bottom plate 7-1-1 to flip upward, and the sawtooth bag breaking blade 7-3 installed thereon cuts the garbage bag, causing the domestic garbage to fall out of it. Among them, there is a pair of bottom plates 7-1-1, and the gap between them is 90 degrees with the arrangement position of the manipulator 6. When working, the manipulator 6 fixes the two ends of the garbage bag, and the bottom plate 7-1-1 flips upward. When it contacts the garbage bag, the horizontal component of the force direction of the garbage bag is consistent with the arrangement direction of the manipulator 6. At this time, the manipulator 6 plays a limiting role, limiting the swing of the garbage bag, thereby effectively achieving the bag breaking effect.

[0050] The screw motors 8-1 and 14-1 control the movement of the nut seats 8-5 and 14-4 on the transmission screw, driving the manipulator 6 holding the garbage bag under the beam to move above the garbage bag guide plate 13, and then the internal servo of the manipulator 6 controls it to loosen the garbage bag, and the garbage bag falls into the conveyor belt 10-5 through the garbage bag guide plate 13.

[0051] The motor 10-1 drives the synchronous belt 10-3, and the synchronous belt 10-3 drives the driving shaft 10-4 matched with the other end to rotate, and the driving shaft 10-4 drives the driven shaft 10-5 and the conveyor belt 10-6 to operate, and the garbage bags are output to the same location, finally realizing the breaking of the bagged domestic garbage and the separate collection of the garbage bags.

[0052] like Fig. 9 As shown. The device replaces the intelligent classification trash bin delivery part, and various garbage recycling bins are placed below it. When in use, bagged garbage is placed in various classification trash bins respectively, and after the bags are broken, the garbage falls into the garbage recycling bin below them. The manipulator 6 transports the broken and separated garbage bags to the garbage bag recycling bin set on the far right of the intelligent classification trash bin through the garbage bag transmission component 10 for subsequent centralized processing.
