[0067] The following is a description of the implementation of the present invention by specific embodiments. People familiar with the art can easily understand other advantages and effects of the present invention from the contents disclosed in this specification. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0068] In a specific embodiment, Figure 1-Figure 5 As shown, the waste bottle recycling equipment provided by the present invention includes a box body 1, a pretreatment component, a lifting component 5 and a storage bin 2. The box body 1 includes a side panel and a top panel. A feeding port 11 is provided on the side panel, and a ventilation hole plate 13 and a discharge port 12 are provided below the side panel. An adjustment support 14 can also be installed at the bottom of the box body 1. The feeding port 11 is used for users to put the bottles to be recycled into the equipment. Its size design should be able to adapt to the size of common waste bottles to ensure that the bottles can enter smoothly. The pretreatment component receives the bottles entering the feeding port 11 and pretreatments the bottles. The purpose of pretreatment is to prepare for subsequent processing procedures, such as identifying the type of bottles, evaluating prices, preliminary sorting, flattening, etc. The lifting component 5 is located downstream of the pretreatment component. After the pretreated bottles leave the pretreatment component, they enter the lifting component 5. The lifting component 5 is used to lift the bottles to a certain height so that they can fall into the storage bin 2. The discharge end of the lifting component 5 is connected to the opening of the storage bin 2, and the bottle body falls into the storage bin 2 through the lifting component 5. The bottle body falls into the storage bin 2 through the lifting component 5 for storage. The storage bin 2 is used for centralized storage of the recovered bottles, waiting for subsequent unified processing.

[0069] During operation, when waste bottles need to be recycled, the waste bottles are put into the box body 1 from the feeding port 11, and the waste bottles first fall into the pre-processing component, where they are identified, evaluated and flattened, and then the flattened waste bottles are transported to the storage bin 2 through the lifting component 5, where they are stored and wait to be transported to a waste collection station or other post-processing site. In this way, the waste bottle recycling device facilitates the recycling of waste bottles, and can achieve one-stop processing of recycling, classification, flattening and storage, thereby improving the efficiency and convenience of waste bottle recycling.

[0070] In some embodiments, the pre-processing component includes an identification mechanism and a bottle pressing mechanism 4 .

[0071] The identification mechanism includes a conveyor belt 31 for conveying the bottle body, and an image acquisition device 32 arranged above the conveyor belt 31; the image acquisition device 32 is used to collect image information of the bottle body on the conveyor belt 31, and identify the evaluation price of the bottle body according to the image information. The conveyor belt 31 is driven by a motor, and the motor drives the conveyor belt 31 to rotate through transmission parts such as a transmission belt or a chain, so as to realize the conveyance of the bottle body. The image acquisition device 32 is fixedly installed on the bracket above the conveyor belt 31 and is electrically connected to the control system. When the bottle body is transported to the collection range of the image acquisition device 32, the collected image information is transmitted to the control system for analysis and processing. During the working process, the bottle body falls on the conveyor belt 31 after being put into the feeding port 11. The conveyor belt 31 transports the bottle body forward, and the image acquisition device 32 collects images of the bottle body during the conveying process. The control system identifies the type, brand and other information of the bottle body according to the collected image information through a preset algorithm, and evaluates its price. The identification mechanism can automatically identify the bottle body and evaluate the price, which provides a standardized pricing basis for the recycling of waste bottles and improves the recycling efficiency and fairness. Theoretically, the identification mechanism may also use a laser scanning device to identify the bottle information by scanning the features on the bottle surface; the conveyor belt 31 may be made of different materials and structures, such as a mesh conveyor belt 31, etc., to adapt to the transportation of different types of bottles.

[0072] like Figure 6-Figure 8 As shown, the bottle pressing mechanism 4 is arranged downstream of the identification mechanism, and the bottle body enters the lifting assembly 5 after being flattened by the bottle pressing mechanism 4. The bottle pressing mechanism 4 is connected with the conveyor belt 31 of the identification mechanism through mechanical structure or electrical control to ensure that the bottle body smoothly enters the bottle pressing mechanism 4 from the identification mechanism; the power transmission is realized between the various components of the bottle pressing mechanism 4 through transmission components such as motors, transmission belts, and chains. During the working process, the bottle body processed by the identification mechanism enters the bottle pressing mechanism 4, and the bottle pressing mechanism 4 applies pressure to the bottle body to flatten the bottle body, and the flattened bottle body enters the lifting assembly 5 again; in this way, the volume of the bottle body can be reduced by flattening the bottle body through the bottle pressing mechanism 4, which is convenient for subsequent storage and transportation, and improves the storage efficiency and transportation efficiency of the equipment.

[0073] Specifically, the bottle pressing mechanism 4 includes a positioning frame 41, a conveying assembly and a pressing wheel assembly; wherein the positioning frame 41 is installed in the box 1, and is used to install the conveying assembly and the pressing wheel assembly, the bottle moves with the conveying assembly, the pressing wheel assembly is arranged at the end of the conveying chain, and the bottle is flattened by the pressing wheel assembly. The conveying assembly can be in the form of a conveying chain or a conveying belt 31, and the conveying assembly can be driven by a motor, and the motor drives the conveying chain or the conveying belt 31 to move through a transmission component, and the bottle is placed on the conveying chain and moves with it; the pressing wheel of the pressing wheel assembly is driven by a pressing wheel motor 48, and the pressing wheel motor 48 drives the pressing wheel to rotate through a transmission component. During the working process, the bottle is placed on the conveying chain or the conveying belt 31 of the conveying assembly, and the conveying chain or the conveying belt 31 conveys the bottle to the pressing wheel assembly, and the pressing wheel of the pressing wheel assembly applies pressure to the bottle to flatten the bottle. In this way, through the cooperation of the conveying assembly and the pressing wheel assembly, the continuous conveying and flattening of the bottle is realized, and the bottle pressing efficiency is improved.

[0074] In order to facilitate the bottle to fall accurately on the conveyor belt 31 or conveyor chain, a guide plate is provided at the front end of the conveyor chain or conveyor belt 31, one end of the guide plate is butted against the discharge end of the identification mechanism, and the other end is located on the conveying surface of the conveyor chain or conveyor belt 31, so as to ensure that the bottle can fall at an appropriate position. One side of the guide plate close to the discharge end of the identification mechanism is higher than the other side of the guide plate, so that the bottle can slide down by its own gravity.

[0075] The conveying component is preferably in the form of a conveying chain. The chain has good structural stability and can provide greater friction to the bottle body to prevent the bottle body from falling off during transportation.

[0076] Specifically, the conveying assembly includes a first conveying chain group and a second conveying chain group, the first conveying chain group includes a first transmission assembly, a first driving sprocket 42 connected to the power member through the first transmission assembly, a first driven sprocket rotatably mounted on the positioning frame 41, and a first conveying chain 43 connected to the first driving sprocket 42 and the first driven sprocket, the bottle body is placed on the first conveying chain 43 and moves with the first conveying chain 43; the second conveying chain group includes a second transmission assembly, a second driving sprocket 44 connected to the power member through the second transmission assembly, a second driven sprocket rotatably mounted on the positioning frame 41, and a second conveying chain 45 connected to the second driving sprocket 44 and the second driven sprocket; wherein the minimum spacing between the first conveying chain 43 and the second conveying chain 45 in the height direction is less than the thickness of the bottle body and greater than one-third of the thickness of the bottle body. It should be understood that the main function of the conveyor chain is pre-pressing to initially flatten the bottle so that it can smoothly enter the downstream pressure wheel assembly. Therefore, the distance between the two conveyor chains is as small as possible. It is advisable to flatten the bottle as much as possible while ensuring that the bottle can pass smoothly after flattening.

[0077] During operation, the bottle falls on the first conveyor chain 43. As the first conveyor chain 43 moves, when the bottle moves between the first conveyor chain 43 and the second conveyor chain 45, due to the spacing between the two, the bottle is pre-flattened by the two conveyor chains. That is, the bottle is flattened by the two conveyor chains before entering the pressing wheel assembly, thereby improving the efficiency and effect of the flattening process. The first conveyor chain group and the second conveyor chain group can also be driven by the same motor to ensure the synchronization of their movements, or they can be driven by two independent motors.

[0078] In some embodiments, the pressure wheel assembly includes an active pressure wheel 46, a driven pressure wheel 47 and a pressure wheel motor 48, the active pressure wheel 46 has a first annular groove 461 on its wheel surface; the driven pressure wheel 47 has a second annular groove 471 on its wheel surface, there is a first preset distance between the active pressure wheel 46 and the driven pressure wheel 47, there is a second preset distance between the bottom of the first annular groove 461 and the bottom of the second annular groove 471; the pressure wheel motor 48 is respectively connected to the active pressure wheel 46 to drive the active pressure wheel 46 to rotate.

[0079] Theoretically, during rolling, there is play in the bearings of the pressing wheel and elastic deformation of mechanical parts such as the pressing wheel. If there is insufficient preload, the plastic bottle will be elastically deformed after being flattened and cannot be effectively flattened. When the pressure is very high, the elastic deformation of the flattened edge of the bottle will change to plastic deformation, and the edge will be torn to a certain extent, and the air in the bottle will be expelled. Therefore, the first preset spacing is usually small and can be zero spacing or even negative spacing, so that there is appropriate preload between the two wheels to improve the compaction effect.

[0080] Since some bottle caps are thick and hard, the degree of flattening cannot reach the flattening effect of the bottle body. In order to ensure that the bottle cap can pass smoothly, the second preset distance is usually the size of a regular bottle cap, about 36 mm.

[0081] When the bottle body enters between the active pressing wheel 46 and the driven pressing wheel 47, the bottle body moves between the two pressing wheels under the drive of the conveyor chain, and the rotation of the active pressing wheel 46 rolls the bottle body into the gap between the two pressing wheels. The driven pressing wheel 47 contacts the bottle body and moves with it. Under the squeezing action of the two pressing wheels, the bottle body is flattened; at the same time, a larger passing space is formed between the first annular groove 461 and the second annular groove 471 to facilitate the passage of the bottle cap and avoid the bottle cap from getting stuck.

[0082] Further, in order to reduce space occupation and reduce the volume of the equipment, the above-mentioned pressure roller motor 48 can serve as the power member of the first conveying chain group and the second conveying chain group, that is, the conveying assembly and the pressure roller assembly share a motor (named as the pressure roller motor 48 for ease of description). At this time, the first transmission assembly includes a transmission sprocket 49 installed on the output shaft of the pressure roller motor 48, and the transmission sprocket 49 is connected to the first driving sprocket 42 through the transmission chain 410; the output shaft of the pressure roller motor 48 rotates to drive the transmission sprocket 49 to rotate, thereby transmitting the rotation to the first driving sprocket 42 through the transmission chain 49, driving the first driving sprocket 42 to rotate, and then driving the first conveying chain 43 to move. The second transmission assembly includes a driving gear 411 installed on the axle of the first driving sprocket 42, and a driven gear 412 installed on the second driving sprocket 44; the rotation of the first driving sprocket 42 drives the axle to rotate, thereby driving the driving gear 411 on the axle to rotate synchronously, and then through the meshing of the driving gear 411 and the driven gear 412, the second driving sprocket 44 is driven to rotate, and finally drives the second conveying chain 45 to move.

[0083] That is, the active pressure wheel is directly connected to the reduction box, the driven pressure wheel has no power, the driven wheel fits the active wheel, and the friction transmission is carried out, and the driven wheel has a preload spring 413, when encountering an object that cannot be flattened, it will bounce upward to achieve elastic avoidance to avoid jamming. Further, in order to increase the friction force during conveying, the first conveying chain and the second conveying chain can be set as a chain structure with barbs.

[0084] In some embodiments, the lifting assembly 5 includes a lifting frame, a lifting motor, a lifting chain 51 and a lifting belt 52; the lifting frame includes a lower horizontal section, a vertical section and an upper horizontal section connected to the discharge end of the bottle pressing mechanism 4, the bottom end of the vertical section is connected to the lower horizontal section, and the top end of the vertical section is connected to the upper horizontal section; the lifting belt 52 covers the range of the lower horizontal section, the vertical section and the upper horizontal section; the lifting chain 51 is connected to the lifting motor by transmission and moves in the vertical direction under the drive of the lifting motor; there are two lifting chains 51, which are respectively arranged on both sides of the vertical section, and the lifting belt 52 moves vertically under the pull of the lifting chain 51, and the lifting belt 52 moves vertically with the lifting chain 51, and at least one support plate 53 for carrying the bottle body is installed on the lifting belt 52. Multiple support plates 53 can be provided, and each support plate 53 is arranged at intervals in the moving direction of the lifting belt 52. The distance between two adjacent support plates 53 should be sufficient to accommodate the bottle body. The provision of multiple support plates 53 can realize the simultaneous transportation of multiple bottles, thereby improving work efficiency.

[0085] During operation, the bottle body flattened by the bottle pressing mechanism 4 falls on the support plate 53, and the lifting motor drives the lifting chain 51 to move, and the lifting chain 51 drives the lifting belt 52 and the support plate 53 to rise vertically, lifting the bottle body to the opening of the storage bin 2, and the bottle body falls from the support plate 53 into the storage bin 2. The bottle body is lifted to the storage bin 2 by the lifting assembly 5, which realizes the transfer of the bottle body at different heights and facilitates the storage of the bottle body; the lifting mechanism is arranged vertically, which improves the space utilization rate in the box body 1 and reduces the floor space occupied by the equipment.

[0086] Furthermore, the waste bottle recycling equipment also includes a discharge mechanism, which is connected to the storage bin 2 and outputs the bottles in the storage bin 2 through airflow. When unloading is required, the discharge mechanism generates airflow, and the airflow sucks the bottles in the storage bin 2 through the pipe connected to the storage bin 2 and outputs the bottles to the equipment, thereby realizing automatic unloading of the bottles in the storage bin 2, reducing the workload of manual unloading and improving the unloading efficiency. In theory, the discharge mechanism can adopt other unloading methods such as mechanical pushing, and the airflow can be generated by different types of fans or air pumps.

[0087] In order to facilitate unloading, a discharge port 12 is provided on the box body 1, and a discharge port 213 is provided at the bottom of the storage bin 2. The unloading mechanism includes a negative pressure fan and a discharge pipe 6. The discharge pipe 6 communicates with the discharge port 12 and the discharge port 213, and the negative pressure fan is located at one end of the discharge port 12 of the discharge pipe 6. When unloading is required, the negative pressure fan is started, and the negative pressure fan generates negative pressure in the discharge pipe 6. The bottles in the storage bin 2 enter the discharge pipe 6 through the discharge port 213 under the action of negative pressure, and then are discharged from the discharge port 12. The unloading of the bottles is realized by using the negative pressure principle, which has a simple structure, convenient operation, and a relatively stable unloading process.

[0088] like Fig. 9 and Fig.10 As shown, the storage bin 2 includes a bin body 21, a discharge door 212, a material discharging motor 22, a lower material discharging arm 23 and an upper material discharging arm 24; wherein, the bin body 21 includes a bottom plate 211 with a planar structure and an annular side plate arranged above the bottom plate 211, the top of the annular side plate forms the opening, the discharge port 213 is opened on the bottom plate 211, and the bottom of the bin body 21 is a planar structure, which can increase the available space of the storage bin 2. The discharge door 212 can be installed on the bottom plate 211 in an openable and closable manner to open or close the discharge port 213; the lower material discharging arm 23 is connected to the material discharging motor 22 through a first one-way bearing, and rotates along a first direction under the drive of the material discharging motor 22; the upper material discharging arm 24 is connected to the material discharging motor 22 through a second one-way bearing, and rotates along a second direction under the drive of the material discharging motor 22; in the process of feeding into the storage bin 2, the rotation of the upper material discharging arm 24 is utilized to flatten the waste bottles as much as possible, thereby improving the space utilization rate of the storage bin 2; one of the first direction and the second direction is clockwise, and the other is counterclockwise.

[0089] When unloading is required, the discharge door 212 is opened, and the material-discharging motor 22 is started. The material-discharging motor 22 rotates. Due to the action of the one-way bearing, the lower material-discharging arm 23 rotates in the first direction, and the upper material-discharging arm 24 does not rotate. The bottle body in the bin body 21 is pushed toward the discharge port 213 through the lower material-discharging arm 23, and the bottle body is pushed out of the storage bin 2.

[0090] The above specific implementation methods further illustrate the purpose, technical solutions and beneficial effects of the present invention in detail. It should be understood that the above are only specific implementation methods of the present invention and are not intended to limit the scope of protection of the present invention.
