[0032] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without making creative efforts shall fall within the protection scope of the present invention.

[0033] Embodiment 1

[0034] This embodiment provides an automatic sorting device for packaging bottles, which includes a conveying mechanism 2, a feeding channel 1, a material leveling mechanism 3, a magnetic separation mechanism 4 and an optical sorter 5. The material leveling mechanism 3 is arranged in the middle of the starting end of the conveying mechanism 2 and is used to disperse the materials entering the conveying mechanism 2 to make the materials evenly distributed. The feeding channel 1 is inclined, and the lower inclined end is placed above the starting end of the conveying mechanism 2 on one side of the material leveling mechanism 3. The feeding channel 1 is supported by a support column 6. The magnetic separation mechanism 4 is arranged on one side of the conveying mechanism 2 and extends above the conveying mechanism 2. A collection box 7 is also arranged below the magnetic separation mechanism 4, and a scraping plate member 8 is also arranged in the collection box 7 for scraping and collecting the materials adsorbed on the magnetic attraction mechanism. As Figure 5 shown, the optical sorter 5 is arranged at the end of the conveying mechanism 2.

[0035] In this embodiment, the starting end and the ending end of the conveying refer to the conveying direction of the conveying mechanism 2 as the conveying front. The starting position of the first conveying is the starting end of the conveying, and the last position of the conveying is the ending end of the conveying.

[0036] In this embodiment, a material leveling mechanism 3 is arranged at the starting end of the conveying mechanism 2. After the materials enter the conveying mechanism 2 from the feeding channel 1, the packaging bottles are dispersed by the material leveling device to achieve uniform distribution, and the magnetic separation mechanism 4 is used to magnetically separate the evenly distributed materials on the conveying mechanism 2, and the packaging bottles containing ferromagnetic materials on the conveying mechanism 2 are sorted out efficiently and completely, ensuring the purity of the subsequent recycled packaging bottles for making new products.

[0037] Embodiment 2

[0038] Based on the above embodiment, the conveying mechanism 2 of this embodiment includes a conveyor belt 21. As Figure 1 shown, transmission rollers 22 are respectively arranged inside the two side ends of the conveyor belt 21, and rotating shafts 23 are fixedly sleeved inside the transmission rollers 22. A material protection frame 24 is arranged outside the conveyor belt 21. Both ends of the two rotating shafts 23 rotate through the material protection frame 24 outward. A conveying motor 25 is arranged on the side surface of the material protection frame 24 at the starting end of the conveying. The conveying motor 25 is in transmission connection with the corresponding end of the corresponding rotating shaft 23. Limit plates 26 are arranged at the other end of the rotating shaft 23 corresponding to the starting end of the conveying and at both ends of the rotating shaft 23 corresponding to the ending end of the conveying. The limit plates 26 are arranged outside the material protection frame 24.

[0039] When this embodiment is in use, the rotating shaft 23 is driven to rotate by the rotation of the conveying motor 25. The rotation of the rotating shaft 23 drives the transmission roller 22 to rotate. The rotation of the transmission roller 22 drives the operation of the conveyor belt 21, thereby driving the materials placed on the conveyor belt 21 to be conveyed and sorted. The setting of the material protection frame 24 can limit the packaging bottle materials located on the conveyor belt 21 to prevent them from slipping out of the conveyor belt.

[0040] Embodiment 3

[0041] Based on the above embodiments, in order to prevent the packaging bottle from slipping out or popping out of the conveying mechanism 2, the material protection frame 24 of this embodiment extends upward at the part corresponding to the starting end of the material conveying to form a U-shaped material blocking frame 10, as Figure 2 shown. The material leveling mechanism 3 is arranged in the middle of the unopened end of the U-shaped material blocking frame 10 and extends above the conveyor belt 21 inside the material blocking frame 10. The feeding channel 1 is located above the material blocking frame 10, and the inclined lower end is arranged close to the material leveling mechanism 3.

[0042] Since the material enters from the material blocking frame 10, accumulates centrally after entering, and is scattered and leveled by the material leveling mechanism 3, the material blocking frame 10 can effectively block the material and prevent the material from leaking out of the conveyor belt 21.

[0043] Embodiment 4

[0044] Based on the above embodiments, the material leveling mechanism 3 of this embodiment includes a fixed column plate 31, a horizontal support plate 32, a material leveling motor 33 and a material leveling rod 34, as Figure 2 and 3 shown. The fixed column plate 31 is arranged in the middle of the unopened end of the U-shaped material blocking frame 10 (since the U-shaped structure itself has one end open and one end unopened, the unopened end in the present invention corresponds to the starting end of the material protection frame 24 for conveying). One end of the horizontal support plate 32 is connected to the fixed column plate 31, and the other end extends horizontally above the conveyor belt 21. The material leveling rod 34 penetrates through the other end of the horizontal support plate 32 and can rotate within the horizontal support plate 32. A limiting turntable 35 with an outer diameter larger than that of the material leveling rod 34 is provided at the top of the material leveling rod 34 and is limited to the top of the horizontal support plate 32. Rotating teeth 36 are evenly arranged on the side surface of the limiting turntable 35. The material leveling motor 33 is arranged at the bottom of the horizontal support plate 32 and is drivingly connected to a transmission shaft 37. The transmission shaft 37 penetrates upward through the horizontal support plate 32, and a transmission gear 38 is fixedly sleeved on the part of the upper surface of the horizontal support plate 32. The transmission gear 38 meshes with the rotating teeth 36 on the limiting turntable 35; a plurality of material leveling plates 39 are evenly arranged along the circumference at the bottom of the material leveling rod 34.

[0045] Preferably, this embodiment further includes a reinforcing rod 11. One end of the reinforcing rod 11 is fixed to the bottom of the horizontal support plate 32, and the other end is fixed to the material protection frame 24 or the material blocking frame 10 below the fixed column plate 31.

[0046] The material leveling mechanism 3 in this embodiment indirectly drives the material leveling rod 34 to rotate through the material leveling motor 33, that is, drives a plurality of material leveling plates 39 to rotate to quickly and evenly spread the centrally placed material on the conveyor belt 21, ensuring the uniformity of subsequent magnetic separation.

[0047] The reinforcing rod 11 in this embodiment can enhance the setting stability of the material leveling mechanism 3. Strengthen the support strength of the fixed column plate 31 and the horizontal support plate 32 for the material leveling motor 33, the material leveling rod 34 and the material leveling plates 39, etc.

[0048] Example 5

[0049] Based on the above embodiments, in order to efficiently magnetically separate magnetic substances in the packaging bottles, the magnetic separation mechanism 4 of this embodiment includes a magnetic separation motor 41, a magnetic separation shaft 42, and a magnetic separation disk 44. As shown in Figure 2 Figure 2 and 4 , the magnetic separation motor 41 is arranged on one side of the material protection frame 24. The magnetic separation shaft 42 is vertically arranged, and its lower end is drivingly connected to the magnetic separation motor 41. A magnetic separation sleeve 43 is provided at the upper end. The magnetic separation disk 44 is fixedly arranged on the magnetic separation sleeve 43. The radius of the magnetic separation disk 44 is equal to the horizontal distance between the center of the magnetic separation shaft 42 and the side surface of the material protection frame 24 far from the magnetic separation shaft 42. The material of the magnetic separation disk 44 is a magnet.

[0050] When the magnetic separation mechanism 4 in this embodiment is specifically used, the magnetic separation disk 44 is indirectly driven to rotate by the magnetic separation motor 41. When the magnetic separation disk 44 rotates above the conveyor belt 21, magnetic separation is performed on the materials on the conveyor belt 21, and the packaging bottles or magnetic impurities containing magnetic materials are attracted and rotated to the collection box 7, where they are scraped off by the scraping plate member 8 for collection. The magnetic attraction effect is good, and the sorting is comprehensive and efficient.

[0051] Example 6

[0052] Based on the above embodiments, the horizontal cross-section of the collection box 7 in this embodiment is fan-shaped, and the magnetic separation motor 41 is located at the vertex formed by the two straight side surfaces in the collection box 7. The radius of the collection box 7 is greater than the radius of the magnetic separation disk 44. The scraping plate member 8 is arranged in the collection box 7.

[0053] The shape and radius of the collection box 7 are adapted to the magnetic separation disk 44, which is convenient for collecting the magnetically separated materials and preventing the magnetic materials from falling out of the collection box 7.

[0054] Example 7

[0055] Based on the above embodiments, in order to effectively scrape off the magnetically separated substances, the side end of the scraping plate member 8 far from the magnetic separation motor 41 is connected to the inner side of the arc surface of the collection box 7, and the upper part of the side end close to the magnetic separation motor 41 extends to be close to the magnetic separation shaft 42. The top of the scraping plate member 8 is in sliding contact with the magnetic separation disk 44 or the distance between the scraping plate member 8 and the magnetic separation disk 44 is 1-2 mm. Taking the rotation direction of the magnetic separation disk 44 as the rotation front, the scraping plate member 8 is arranged in the collection box 7 close to the straight side surface located in the rotation front.

[0056] Since the horizontal cross-section of the collection box 7 is mountain-shaped, its side surface includes two connected straight side surfaces and an arc surface.

[0057] The structure and size of the scraping plate member 8 are set to facilitate scraping off the materials adsorbed by the magnetic suction disk completely and ensure that the scraped materials can all fall into the collection box 7 for collection.

[0058] Example 8

[0059] Based on the above embodiments, in order to ensure the comprehensiveness of magnetic separation, vibration mechanisms 9 are respectively provided on both sides of the material protection frame 24 corresponding to the magnetic separation mechanism 4 in this embodiment. The vibration mechanism 9 includes two vibration plates 91. The two vibration plates 91 are arranged in parallel on the inner side of the corresponding material protection frame 24, and are respectively located above and below the upper conveyor belt 21 layer. The two vibration plates 91 are in contact with the conveyor belt 21, and the conveyor belt 21 can move between the two vibration plates 91. Vibrators 92 are uniformly arranged on the two vibration plates 91 along the conveying direction of the conveyor belt 21.

[0060] The conveyor belt 21 generally includes upper and lower layers, that is, the upper and lower conveyor belt 21 layers.

[0061] The setting of the vibration mechanism 9 in this embodiment can, through the vibration of the vibrators 92, transmit the vibration to the upper conveyor belt 21 layer in contact with the vibration plates 91. The vibration of the upper conveyor belt 21 layer drives the vibration of the materials conveyed by it, and thus it is more convenient for the magnetic suction cups to perform magnetic separation on the vibrating materials, improving the separation quality and efficiency.

[0062] Embodiment 9

[0063] Based on the above embodiments, the optical sorter 5 in this embodiment is a TOMRA series optical sorter 5 or a Sesotec series optical sorter 5.

[0064] As another implementation manner, the optical sorter 5 can also select other series of optical sorters 5 that can be used for sorting packaging bottles by color or material.

[0065] Embodiment 10

[0066] On the basis of the above embodiments, this embodiment provides a sorting method based on the packaging bottle sorting device, as Figure 6 shown, which specifically includes the following steps:

[0067] S1. Sorting preparation and feeding: Start the conveying motor 25, the material leveling motor 33, and the magnetic separation motor 41, and start the vibrator 92 and the sorter. Pour the collected packaging bottles to be sorted into the feeding channel 1, and the packaging bottles enter the starting end of the material conveying mechanism from the feeding channel 1;

[0068] S2. Material leveling: The packaging bottle materials entering the conveyor belt 21 are concentrated and piled up. Start the material leveling motor 33 to drive the transmission gear 38 to rotate, and then drive the limit turntable 35 meshed with the transmission gear 38 through the rotating teeth 36 to rotate. The rotation of the limit turntable 35 drives the material leveling rod 34 to rotate, and the rotation of the material leveling rod 34 drives each material leveling plate 39 to rotate to disperse the packaging bottle materials so that the packaging bottle materials are quickly and evenly spread on the conveyor belt 21;

[0069] S3. Magnetic separation: The packaging bottle materials evenly distributed on the conveyor belt 21 are conveyed along the conveying direction of the conveyor belt 21 to the vibration mechanism 9. The vibration of the vibrator 92 drives the corresponding position of the conveyor belt 21 to vibrate, and then the packaging bottles conveyed to the corresponding position follow the vibration; the rotation of the magnetic separation motor 41 drives the rotation of the magnetic separation shaft 42, and then drives the rotation of the magnetic separation disc 44. When the magnetic separation disc 44 rotates above the conveyor belt 21, magnetic attraction selection is performed on the vibrating packaging bottles. The packaging bottles that can be magnetically attracted are sucked to the bottom of the magnetic suction disc and rotate with the magnetic suction disc to above the collection box 7;

[0070] S4. Magnetic separation and scraping: The magnetic suction disc with the sucked packaging bottles rotates to above the collection box 7 and then rotates to the scraping plate member 8. The scraping plate member 8 scrapes the packaging bottles sucked on the magnetic suction disc, and the packaging bottles that can be magnetically attracted are scraped into the collection box 7 for collection. The magnetic suction disc that has been scraped clean by the scraping plate member 8 continues to rotate above the conveyor belt 21 for magnetic separation. In this way, the packaging bottle materials are sorted repeatedly;

[0071] S5. Sorting by the optical sorter 5: The packaging bottle materials after magnetic separation are conveyed into the optical sorter 5 along with the conveyor belt 21, and the optical sorter 5 sorts the packaging bottles according to the material or according to the color.

[0072] The above-described embodiments only describe the preferred embodiments of the present invention, and do not limit the concept and scope of the present invention.

10. A method for sorting packaging bottles, characterized in that: The sorting method is implemented by the above-mentioned sorting device, and specifically comprises the following steps: S1. Sorting preparation and feeding: Start the conveying motor, the material distribution motor and the magnetic separation motor, and start the vibrator and the sorting machine, pour the collected packaging bottles to be sorted into the feeding channel, and the packaging bottles enter the feeding channel to the beginning of the feeding mechanism; S2. Material distribution: The packaging bottles on the conveyor belt are concentrated and piled up, and the distribution motor is started to drive the transmission gear to rotate, which in turn drives the limit turntable that is meshed with the rotating gear and the transmission gear to rotate. The rotation of the limit turntable drives the distribution rod to rotate, and the rotation of the distribution rod drives each distribution plate to rotate to break up the packaging bottles so that the packaging bottles can be quickly and evenly laid on the conveyor belt; S3. Magnetic separation: The bottle materials evenly distributed on the conveyor belt are transported to the vibrating mechanism along the conveying direction of the conveyor belt. The vibration of the vibrator drives the conveyor belt at the corresponding position to vibrate, and then the bottles transported to the corresponding position follow the vibration; the rotation of the magnetic separation motor drives the magnetic separation shaft to rotate, and then drives the magnetic separation disk to rotate. When the magnetic separation disk rotates above the conveyor belt, the vibrating bottles are magnetically selected. The bottles that can be magnetically attracted are attracted to the bottom of the magnetic suction disk and rotate with the magnetic suction disk to the top of the collection box; S4. Magnetic separation and scraping: The magnetic suction cup with the bottles sucked on it rotates to the top of the collection box and then to the scraping plate. The bottles sucked on the magnetic suction cup are scraped by the scraping plate. The bottles that can be magnetically sucked are scraped into the collection box for collection. The magnetic suction cup that has been scraped clean by the scraping plate continues to rotate to the top of the conveyor belt for magnetic separation. The bottles are sorted in this way. S5. Sorting by optical sorter: The packaging bottles that have been sorted by magnetic attraction are transported to the optical sorter through the conveyor belt, and the optical sorter is used to sort the packaging bottles according to material or color.
