Description

Technical Field

[0001] The utility model relates to the technical field of metal waste recycling, and more specifically to the technical field of metal can waste recycling. Background Art

[0002] With the implementation and promotion of various environmental protection laws and regulations, people's awareness of green environmental protection and sustainable development has been continuously enhanced, and garbage classification and recycling has become more and more popular. For some waste metal cans with plastic caps, such as milk powder cans, metal and plastic materials need to be sorted and recycled. However, due to some structural designs of the products themselves, such as the sealed plastic caps, which are often tightly fastened to the can body and difficult to remove, the recycled materials will contain plastic and metal mixed, which is not conducive to subsequent garbage classification and recycling.

[0003] The Chinese patent with the authorization announcement number: CN 219988183 U discloses a metal-plastic separator. After the material enters the feed port, it is first crushed into material powder by a crushing component, and then the plastic and metal in the material powder are separated by high-voltage static electricity, and enter the corresponding metal recovery box and plastic recovery box respectively, so as to facilitate subsequent recycling and reprocessing.

[0004] However, due to the large volume of the recycled objects, the metal-plastic separator needs to be crushed first and then separated by high-voltage electrostatic separation, which requires high equipment costs and time costs. In addition, the regular maintenance and replacement costs of the internal components of the device are high, further increasing the cost of waste recycling. Utility Model Content

[0005] The utility model aims to provide a special recycling device for metal cans containing plastic covers, which can carry out special classification and recycling of metals and plastics for waste metal cans containing plastic covers, and the cost is controllable.

[0006] The utility model is realized through the following technical solutions:

[0007] A special recycling device for metal cans with plastic caps, comprising a shell, a feed port being provided on the shell, a separation component, a metal recovery box and a plastic recovery box being provided in the shell, and characterized in that the separation component comprises a separation platform, a compression device and a magnetic suction device, the compression device being located above the separation platform and being used for compressing and separating the metal cans with plastic caps, a drop gap being provided between the separation platform and the shell, and the separated plastic caps falling into the plastic recovery box located below the separation platform through the drop gap, the magnetic suction device comprising a magnetic component for adsorbing the metal can body and a moving component connected to the magnetic component, and the metal can body is dropped into the metal recovery box through the cooperation of the magnetic component and the moving component.

[0008] The metal can containing the plastic cover falls onto the separation platform inside the recycling device through the feed port, and the compression device located above the separation platform compresses the metal can with the plastic cover so that the plastic cover is separated from the metal can body. The compression device can be a mature mechanical compressor in the prior art, such as a hydraulic compressor or a pneumatic compressor. The mechanical compressor has a long service life and can reduce the later maintenance cost of the recycling device. The plastic recycling box is located below the separation platform, and the separated plastic cover falls into the plastic recycling box through the drop gap. The magnetic component can use a mature magnetic switch in the prior art, and its working principle is to control the generation and disappearance of magnetism by energizing and de-energizing the electromagnet. When the moving component in the magnetic suction device controls the magnetic component to move to a suitable position above the separation platform, the magnetic component generates magnetism, so that the compressed metal can body is adsorbed by the magnetic component. After the metal can body is moved to the top of the metal recycling box by the moving component, the magnetism of the magnetic component disappears, and the metal can body falls into the metal recycling box.

[0009] Metal cans with plastic sealing lids, such as milk powder cans, are a relatively large type of waste in recycling. This type of recycling device can process them in advance, so that the plastic and metal of these metal cans with plastic lids have been separated before being recycled, reducing some picking and sorting links and alleviating the later pressure on the recycling station. At the same time, this type of recycling device can achieve the sorting of plastic lids and metal can bodies through the cooperation of the compression device and the magnetic suction device, and has high work efficiency. In addition, the separation components in this type of recycling device are all of a type that is not prone to wear and tear, have a long service life, and can reduce later maintenance costs.

[0010] As a preferred embodiment of the utility model, the special recycling device for metal cans containing plastic caps also includes a return port, which is located at one end of the separation platform. A return assembly is provided at the other end of the separation platform. The return assembly includes a discriminator and a telescopic device electrically connected to the discriminator. The discriminator is used to determine whether the waste to be recycled is a metal can containing plastic caps, and to control the telescopic device to extend and retract so that the recycled waste is pushed from the separation platform to the return port.

[0011] The discriminator may use the photographic recognition system in the prior art, and confirm whether the waste to be recycled is within the recycling range by presetting the appearance features of the metal can in the system. If so, the subsequent compression and separation steps are performed. If not, it will be pushed from the separation platform to the return port by the resistance of the telescopic device. In addition to the photographic recognition system, the code scanning recognition system in the prior art may also be used to identify the information of the waste to be recycled by scanning the QR code or barcode on the metal can. The design of the return assembly and the return port can prevent the waste that is not within the recycling range from undergoing subsequent processing steps, avoid the appearance of other mixed materials in the recycling box, and reduce unnecessary picking steps. At the same time, it can also prevent some hard objects from damaging the telescopic device, further protect it, extend the service life of the device, and reduce the recycling cost overall.

[0012] As a preferred embodiment of the present invention, the separation component further comprises an infrared sensing device 1 for sensing whether there are waste products to be recycled on the separation platform, and the infrared sensing device 1 is electrically connected to the discriminator.

[0013] Since the discriminator needs to process more complex recognition operations, long-term operation is likely to increase power consumption and accelerate the wear of the carrier equipment. Through the cooperation between the infrared sensing device 1 and the discriminator, the discriminator does not need to be in a working state all the time, and can enter a dormant state when no items to be recycled are put in, which can save power consumption and extend the service life of the discriminator, reducing the subsequent maintenance costs.

[0014] As a preferred embodiment of the present invention, the shape of the feed port is compatible with the shape of the metal can body.

[0015] This can prevent users from putting some obviously eligible waste products into the recycling device, reducing some unnecessary work burdens of the device. At the same time, the shape of the feed port is adapted to the shape of the metal can body, which can more intuitively inform users of the recycling objects of the recycling device, increasing the convenience of use for users.

[0016] As a preferred embodiment of the present invention, the feed port is connected to a horizontal downward feed channel, and the waste to be recycled falls onto the separation platform through the feed channel.

[0017] The design of the feed channel helps the waste to be recycled to fall smoothly onto the separation platform for subsequent processing steps, avoiding the risk of the waste to be recycled accidentally entering other areas or getting stuck at a certain position, thereby increasing the operating stability of the device.

[0018] As a preferred embodiment of the present invention, the separation platform is provided with a limiting portion for limiting the rolling of the waste to be recycled.

[0019] The setting of the limiting part can effectively prevent the waste to be recycled from rolling or falling into other areas, ensuring that it can be effectively identified by the discriminator and ensuring the normal progress of subsequent separation work.

[0020] As a preferred embodiment of the present invention, both the metal recycling box and the plastic recycling box are provided with an infrared sensing device 2 for sensing whether the recycling box is full of items to be recycled.

[0021] The setting of the second infrared sensing device helps the staff to recycle the waste in the recycling bin in time, and prevents the normal operation of the device from being affected due to the waste stored in the recycling bin being too full.

[0022] As a preferred embodiment of the present invention, the special recycling device for metal cans containing plastic lids is also provided with a monitoring and recording device for recording the recycling process.

[0023] The monitoring and recording equipment can transmit images and data of the recycling process in real time, making it easier for the management department to conduct remote management and supervision.

[0024] In summary, the utility model has the following beneficial effects:

[0025] 1. Metal cans with plastic lids have been separated from plastic and metal by special recycling equipment before being recycled, which reduces some picking and sorting links and alleviates the later pressure on recycling stations.

[0026] 2. This recycling device can realize the sorting of plastic covers and metal can bodies through the cooperation of the compression device and the magnetic suction device, and has high working efficiency.

[0027] 3. The separation components are all of a type that is not prone to wear and tear, have a long service life, and can reduce subsequent maintenance costs.

[0028] 4. The design of the material return assembly and the material return port can prevent waste products that are not within the recycling range from undergoing subsequent processing steps, thereby avoiding the presence of other mixed substances in the recycling box and reducing unnecessary picking steps; at the same time, it can also prevent some hard objects from damaging the telescopic device, further protecting it, extending the service life of the device, and reducing the recycling cost as a whole.

[0032] The utility model is further described in detail below in conjunction with the accompanying drawings.

[0033] This specific embodiment is merely an explanation of the present invention and is not a limitation of the present invention. After reading this specification, those skilled in the art may make non-creative modifications to the present embodiment as needed, but such modifications are protected by patent law as long as they are within the scope of the claims of the present invention.

[0034] like Figure 1 , 2 As shown, the metal can containing the plastic cover falls onto the separation platform 51 inside the recycling device through the feed port 1. The shape of the feed port 1 is adapted to the shape of the metal can body. It can prevent users from putting some obviously suitable waste products to be recycled into the recycling device, reducing some unnecessary workload of the device. At the same time, the shape of the feed port 1 is adapted to the shape of the metal can body, which can more intuitively inform the user of the recycling object of this type of recycling device, increasing the user's convenience. Among them, a horizontal downward feeding channel can also be provided between the feed port 1 and the separation platform 51, which helps the waste products to be recycled to fall smoothly onto the separation platform 51 for subsequent processing procedures, avoiding the risk of the waste products to be recycled mistakenly entering other areas or getting stuck at a certain position, and increasing the operating stability of the device.

[0035] The separation platform 51 is provided with grooves and limit parts to prevent the waste to be recycled from rolling or falling into other areas. In addition, the shape of the groove can match the shape of the metal can body, so as to further limit the position of the can body, which is convenient for the implementation of subsequent identification and separation steps. The separation platform 51 is provided with an infrared sensing device 1, and the infrared sensing device 1 is electrically connected to the discriminator. When the infrared sensing device 1 detects that the metal can falls into the designated area of ​​the separation platform 51, it will feed back the signal to the discriminator. The discriminator can use the photographic recognition system in the prior art, and confirm whether the waste to be recycled is within the recycling range by presetting the appearance characteristics of the metal can in the system. If so, the subsequent compression and separation steps are carried out. If not, it will be pushed from the separation platform 51 to the return port 2 by the telescopic device.

[0036] In addition to the photo recognition system, the discriminator can also use the existing scanning recognition system to identify the information of the waste to be recycled by scanning the QR code or barcode on the metal can. The design of the return assembly and the return port 2 can prevent the waste that is not within the recycling range from undergoing subsequent processing steps, avoid the appearance of other mixed materials in the recycling box, and reduce unnecessary picking steps. At the same time, it can also prevent some hard objects from damaging the telescopic device, further protect it, extend the service life of the device, and reduce the recycling cost overall.

[0037] Since the discriminator needs to process more complex recognition operations, long-term operation is likely to increase power consumption and accelerate the wear of the carrier equipment. Through the cooperation of the infrared sensing device and the discriminator, the discriminator does not need to be in a working state all the time, and can enter a dormant state when there are no items to be recycled, which can save power consumption and extend the service life of the discriminator, reducing the subsequent maintenance costs.

[0038] When the discriminator confirms that the object to be recycled is within the recycling range, the compression device 52 located above the separation platform 51 compresses the metal can with plastic cover. After the metal can is compressed, the can body and the plastic shell are separated. The metal can body is located on the separation platform 51, and a drop gap is provided under the plastic cover, so that the plastic cover separated from the can body falls into the plastic recycling box 4. The drop gap can be slightly larger than the size of the plastic cover itself, ensuring that the plastic cover can fall smoothly, while the can body still stays on the separation platform 51.

[0039] The compression device 52 may be a mature mechanical compressor in the prior art, such as a hydraulic compressor or a pneumatic compressor, etc. The mechanical compressor has a long service life and can reduce the later maintenance cost of the recovery device.

[0040] When the moving component in the magnetic suction device 53 controls the magnetic component to move to a suitable position above the separation platform 51, the magnetic component generates magnetism, so that the compressed metal can body is adsorbed by the magnetic component. After the metal can body is moved to the top of the metal recovery box 3 by the moving component, the magnetism of the magnetic component disappears, and the metal can body falls into the metal recovery box 3. The moving component can use a mature hydraulic rod or pneumatic rod in the prior art to drive the magnetic component to move linearly. The magnetic component can use a mature magnetic switch in the prior art, and its working principle is to control the generation and disappearance of magnetism by energizing and de-energizing the electromagnet.

[0041] The metal recycling box 3 and the plastic recycling box 4 are both provided with an infrared sensing device 2 for sensing whether the recycling box is full of items to be recycled. The provision of the infrared sensing device 2 helps the staff to recycle the waste in the recycling box in time, and prevents the normal operation of the device from being affected by the waste stored in the recycling box being too full. In addition, the recycling device is also provided with a monitoring and recording device, which can transmit images and data of the recycling process in real time, so as to facilitate remote management and supervision by the management department.

[0042] As another preferred embodiment of the present invention, the recycling device may also be provided with a display screen to display system information, user information, information about delivered items, and progress of classified recycling, etc. The display screen may also include indicator lights to provide eye-catching status information, etc. A weighing device is provided on the separation platform 51 to weigh the recyclables and return information to the system, and the system displays the corresponding information to the deliverer through the display screen.

[0043] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
