Description

[0002] In order to achieve energy conservation and emission reduction, existing plastic product manufacturers generally recycle discarded plastic products as raw materials for plastic product production. There are many types of plastic products that can be recycled, and common ones include plastic bottles. When recycling plastic bottles, since impurities or other corrosive liquids may be attached to the inside of the plastic bottles, it is often necessary to clean the inside and outside of the plastic bottles.

[0033] One of the preferred embodiments of the present application is as follows: Figure 1As shown, a plastic recycling device includes a frame 1, a conveying device 2, an internal cleaning mechanism 3, an external cleaning mechanism 4 and a crushing mechanism 5. The frame 1 is provided with a loading area 101, a cleaning tank 102 and a crushing tank 103 in sequence. The internal cleaning mechanism 3 and the conveying device 2 are both installed in the loading area 101, and the conveying device 2 is located below the internal cleaning mechanism 3; the external cleaning mechanism 4 is installed in the cleaning tank 102 filled with cleaning liquid, and the crushing mechanism 5 is installed in the crushing tank 103. When it is necessary to crush and recycle the plastic bottle 01, the plastic bottle 01 to be recycled can be placed on the conveying device 2, and the conveying device 2 can transport the plastic bottle 01 to be recycled to the bottom of the internal cleaning mechanism 3, and then the internal cleaning mechanism 3 can position and press the plastic bottle 01 to be recycled and inject cleaning liquid into it and shake it at high speed, so as to use the cleaning liquid to rinse the inner wall of the plastic bottle 01. After the inner wall of the plastic bottle 01 is cleaned, the conveying device 2 can convey the plastic bottle 01 to the cleaning pool 102, and the cleaning liquid inside the plastic bottle 01 can sink the plastic bottle 01 into the cleaning pool 102, and then the outer wall of the plastic bottle 01 is scrubbed by the external cleaning mechanism 4. After the inner and outer walls of the plastic bottle 01 are cleaned, the external cleaning mechanism 4 can convey the plastic bottle 01 to the crushing pool 103 to be crushed by the crushing mechanism 5.

[0034] It is understandable that, compared with the traditional method of crushing first and then cleaning, the present embodiment tilts the plastic bottle 01 first and then crushes it; the structural integrity of the plastic bottle 01 facilitates cleaning, and can effectively avoid the inconvenience caused by the floating of the plastic bottle 01 when it is washed after being crushed in the traditional method. At the same time, by separately setting up the internal cleaning mechanism 3 and the external cleaning mechanism 4 to independently clean the inner and outer walls of the plastic bottle 01, the corrosion of the subsequent crushing mechanism 5 by the internal corrosive liquid can be effectively reduced or avoided, thereby increasing the service life of the crushing mechanism 5. The specific structure and working principle of the crushing mechanism 5 are well known to those skilled in the art, so they will not be elaborated in detail here; generally speaking, the crushing mechanism 5 includes a crushing roller driven by a motor, and the inserted plastic bottle 01 is crushed by the rotation of the crushing roller.

[0035] It should be known that the specific number of the conveying device 2 and the internal cleaning mechanism 3 can be multiple, so as to simultaneously clean and convey the inner walls of multiple plastic bottles 01; the specific number can be selected according to the actual needs of those skilled in the art, for example Figure 1 As shown, there are three conveying devices 2 and three internal cleaning mechanisms 3. The specific structure and working principle of the conveying device 2 are well known to those skilled in the art, so they will not be elaborated in detail here; the conveying device 2 generally adopts a conveyor belt.

[0036] In this embodiment, there are many specific structures of the internal cleaning mechanism 3 that can achieve the above functions. For the sake of easy understanding, the following will be described in detail using one of the structures. Figure 2 and Figure 3 As shown, the internal cleaning mechanism 3 includes a bracket 31, a rotating assembly, a pouring assembly 34, a positioning assembly 35 and a blocking assembly 36. The bracket 31 is fixedly mounted on the loading area 101, the rotating assembly is mounted on the top of the bracket 31, the positioning assembly 35 is mounted on the rotating assembly for pressing and positioning the plastic bottle 01 to be recycled, the pouring assembly 34 is used to inject cleaning liquid into the positioned plastic bottle 01, and the blocking assembly 36 is used to block the opening of the plastic bottle 01; the rotating assembly can drive the positioning assembly 35 to horizontally reciprocate the plastic bottle 01 after the cleaning liquid is injected and the opening is blocked.

[0037] It can be understood that the bracket 31 can be L-shaped as a whole, wherein the vertical section can be fixedly installed on one side of the corresponding conveying device 2, and the horizontal section is fixedly installed on the top of the vertical section and extends directly above the conveying device 2. In this way, when the rotating assembly is installed on the horizontal section, the perfusion assembly 34, the positioning assembly 35 and the blocking assembly 36 can all be located directly above the conveying device 2.

[0038] It should be known that in order to ensure that the plastic bottle 01 can be shaken stably at high speed, it is necessary to align and press it through the positioning component 35. The pressing of the positioning component 35 can also ensure that the perfusion component 34 can stably inject the cleaning liquid into the interior of the plastic bottle 01. It should be known that when the plastic bottle 01 is transported to the bottom of the internal cleaning mechanism 3, the direction of the bottle mouth of the plastic bottle 01 remains consistent. In order to ensure that the cleaning liquid inside the plastic bottle 01 does not splash during the high-speed shaking process, it is necessary to ensure that the bottle mouth of the plastic bottle 01 is stably blocked. Generally speaking, the bottle mouth of the plastic bottle 01 is blocked by a bottle cap, but for the plastic bottles 01 that need to be recycled, some of the bottle mouths of the plastic bottles 01 may not have bottle caps, and some of the bottle caps of the plastic bottles 01 may be loose; therefore, when the plastic bottle 01 is shaken at high speed, the bottle cap of the bottle mouth can be tightened by the blocking component 36, or the bottle mouth without a bottle cap can be blocked. Based on the blocking of the bottle mouth of the plastic bottle 01, the positioning assembly 35 also needs to center the plastic bottle 01. For ease of understanding, the specific structures of the rotating assembly, the pouring assembly 34, the positioning assembly 35 and the blocking assembly 36 will be described in detail below.

[0039] Specifically, there are many specific structures of the rotating assembly that can achieve the above functions, one of which is as follows: Figure 2As shown, the rotating assembly includes a first rotating device 32 and a rotating seat 33. The rotating seat 33 is rotatably mounted on the horizontal section at the top of the bracket 31, and the perfusion assembly 34, the positioning assembly 35 and the plugging assembly 36 are all mounted on the rotating seat 33. A sub-gear 331 is mounted on the outer side of the rotating seat 33. The first rotating device 32 is also fixedly mounted on the horizontal section at the top of the bracket 31 and is located on one side of the rotating seat 33. The first rotating device 32 is engaged with the sub-gear 331 through the main gear 321 installed at the output end to drive the rotating seat 33 to rotate. Based on the structure of the rotating seat 33, the horizontal section at the top of the bracket 31 can also be circular.

[0040] It should be known that the specific structure and working principle of the first rotating device 32 are well-known technologies to those skilled in the art, so they will not be elaborated in detail here; common first rotating devices 32 include motors, rotating cylinders, and rotating hydraulic cylinders, etc. In this embodiment, the first rotating device 32 preferably uses a motor.

[0041] Specifically, there are many specific structures of the positioning component 35 that can achieve the above functions, one of which is as follows: Figure 2 and Figure 3 As shown, the positioning assembly 35 includes a plurality of second telescopic devices 351 and a positioning plate 352. The cross section of the positioning plate 352 is arc-shaped, and the positioning plate 352 is mounted on the lower end surface of the rotating seat 33 through the second telescopic device 351. The positioning plate 352 can press the plastic bottle 01 located on the conveying device 2 under the vertical drive of the second telescopic device 351.

[0042] It is understandable that the plastic bottle 01 is generally a cylindrical structure, so a positioning plate 352 with an arc-shaped cross-section can be set to achieve the compression of the plastic bottle 01, and at the same time, the plastic bottle 01 can also be positioned by squeezing the positioning plate 352 and the plastic bottle 01, so that the axis of the plastic bottle 01 and the axis of the positioning plate 352 are located in the same vertical plane, thereby facilitating the subsequent sealing of the bottle mouth by the sealing component 36.

[0043] It should be known that the specific structure and working principle of the second telescopic device 351 are well-known technologies to those skilled in the art, so they will not be elaborated in detail here; common second telescopic devices 351 include linear motors, cylinders, and hydraulic cylinders, etc. In this embodiment, the second telescopic device 351 preferably uses a cylinder or a hydraulic cylinder.

[0044] Specifically, there are many specific structures of the perfusion component 34 that can achieve the above functions, one of which is as follows: Figure 2 and Figure 3As shown, the perfusion assembly 34 includes a first telescopic device 341 and at least one punching head 342. The first telescopic device 341 is vertically fixedly installed at the center of the rotating seat 33, and the punching head 342 is installed at the output end of the first telescopic device 341 and connected to an external water source. The punching head 342 can move vertically under the drive of the first telescopic device 341 to penetrate the plastic bottle 01 compressed by the positioning assembly 35 and inject the cleaning liquid.

[0045] It should be known that the specific number of the punching heads 342 can be multiple, and multiple punching heads 342 can accelerate the injection of the cleaning liquid. At the same time, during the high-speed shaking of the plastic bottle 01, the multiple punching heads 342 can be kept extended into the plastic bottle 01 to further position the plastic bottle 01.

[0046] It is understandable that the initial position of the punching head 342 is located outside the positioning plate 352, that is, above the positioning plate 352; in order to ensure that the punching head 342 can extend into the plastic bottle 01, it is necessary to open perforations 3520 corresponding to the number and size of the punching head 342 on the top of the positioning plate 352, so that the punching head 342 can extend into the plastic bottle 01 under the drive of the first telescopic device 341 to inject the cleaning liquid. The specific structure and working principle of the first telescopic device 341 are well-known technologies for those skilled in the art, so they will not be elaborated in detail here; common first telescopic devices 341 include linear motors, cylinders, hydraulic cylinders, etc. In this embodiment, the first telescopic device 341 preferably uses a cylinder or a hydraulic cylinder.

[0047] It should also be known that there are many ways for the punching head 342 to penetrate the plastic bottle 01. The punching head 342 can be inserted into the plastic bottle 01 pressed by the positioning component 35 by drilling or melting. For the drilling method, the punching head 342 can have a sharp corner and can adopt a structure similar to that of an injection needle. The center of the punching head 342 can form a water outlet 3420 to facilitate the injection of cleaning liquid. For the melting method, such as Figure 4 As shown, one end of the punching head 342 can be set to a cone, and a heating wire is arranged inside it. The cone head of the punching head 342 is heated by the heating wire to achieve melting and penetration of the plastic bottle 01; a water outlet 3420 is arranged at the center of the punching head 342, and a water inlet 3421 for connecting to a water source is arranged on the side away from the cone head. The water inlet 3421 is connected with the water outlet 3420 inside the punching head 342, and then the external water source can enter the inside of the punching head 342 through the water inlet 3421 and flow into the plastic bottle 01 along the water outlet 3420.

[0048] Specifically, there are many specific structures of the blocking component 36 that can achieve the above functions, one of which is as follows: Figure 2As shown, an extension plate 332 is horizontally arranged on one side of the rotating seat 33; the blocking assembly 36 includes a third telescopic device 361, a fourth telescopic device 362, a second rotating device 365, a plug 363 and a visual unit 364. The third telescopic device 361 is vertically mounted on the extension plate 332, the fourth telescopic device 362 is mounted on the output end of the third telescopic device 361 and is horizontally arranged, the plug 363 is mounted on the output end of the fourth telescopic device 362 through the second rotating device 365; the visual unit 364 is mounted on the output end of the third telescopic device 361. After the plastic bottle 01 is positioned and pressed by the positioning assembly 35, the visual unit 364 can detect the opening state of the plastic bottle 01, and the third telescopic device 361 and the fourth telescopic device 362 can adjust the plug 363 to extend to the opening position of the plastic bottle 01 according to the detected opening position of the plastic bottle 01. If the plastic bottle 01 is open with a cap, the plug 363 can be driven by the second rotating device 365 to rotate the bottle cap in the tightening direction to tighten the bottle cap. If the plastic bottle 01 is open without a cap, the plug 363 directly extends to the bottle mouth of the plastic bottle 01 to seal it.

[0049] It should be known that the specific structures and working principles of the third telescopic device 361, the fourth telescopic device 362, the second rotating device 365, and the visual unit 364 are well known to those skilled in the art, so they will not be elaborated in detail here. Common third telescopic devices 361 and fourth telescopic devices 362 include linear motors, cylinders and hydraulic cylinders, etc., and cylinders or hydraulic cylinders are preferably used in this embodiment. Common second rotating devices 365 include motors, rotating cylinders and rotating hydraulic cylinders, etc., and motors are preferably used in this embodiment. The visual unit 364 generally uses a CCD camera. The plug 363 can be made of flexible materials, such as rubber materials, etc., which can increase the resistance with the bottle cap or improve the sealing performance of the bottle mouth.

[0050] In this embodiment, there are many specific structures of the external cleaning mechanism 4 that can achieve the above functions. For the sake of easy understanding, the following will be described in detail using one of the structures. Figures 5 to 9 As shown, the external cleaning mechanism 4 includes a salvaging assembly 42 and a plurality of roller brush assemblies 41. The roller brush assembly 41 is installed at the bottom of the cleaning tank 102 to scrub the outer surface of the plastic bottle 01 sent into the cleaning tank 102. The salvaging assembly 42 is installed at the upper part of the cleaning tank 102, and the salvaging assembly 42 can salvage the plastic bottle 01 that has been cleaned in the cleaning tank 102 to be transported to the crushing tank 103.

[0051] It should be known that the specific structure and working principle of the roller brush assembly 41 are well known to those skilled in the art, so they will not be elaborated in detail here; generally speaking, the roller brush assembly 41 includes a roller brush and a motor for driving the roller brush to rotate. Multiple roller brush assemblies 41 can increase the area of ​​the cleaning area to achieve the cleaning of more plastic bottles 01. It should be known that the roller brush assembly 41 is installed at the bottom of the cleaning pool. After the inner wall of the plastic bottle 01 is cleaned, the cleaning liquid inside is not removed. Therefore, after the plastic bottle 01 is transported to the cleaning pool 102, it can automatically sink to the bottom of the cleaning pool 102 and be brushed on the outer surface by the roller brush assembly 41. Of course, if the cleaning liquid inside the plastic bottle 01 partially leaks before entering the cleaning pool 102, resulting in a slow sinking time of the plastic bottle 01, the salvage assembly 42 can also be controlled to press the plastic bottle 01 between the liquid levels of the cleaning pool 102 to achieve rapid injection of the cleaning liquid, thereby achieving rapid sinking of the plastic bottle 01.

[0052] In this embodiment, there are many specific structures of the salvage assembly 42 that can achieve the above functions, one of which is as follows: Figure 5 , Figure 6 , Figure 8 and Fig. 9 As shown, the salvage assembly 42 includes a third rotating device 421, a salvage plate 422, a push plate 423 and a traction assembly 424. The cleaning area of ​​the cleaning pool 102 is a circular arc, and the salvage plate 422 is rotatably installed at the center of the cleaning area. The extension length of the salvage plate 422 is equal to the diameter of the cleaning area; the third rotating device 421 is used to drive the salvage plate 422 to rotate, thereby lifting the plastic bottle 01 in the cleaning area; the push plate 423 is slidably installed on the salvage plate 422 and cooperated with the traction assembly 424; the push plate 423 can push the plastic bottle 01 to the crushing pool 103 after the salvage plate 422 salvages the plastic bottle 01.

[0053] It should be noted that the specific structure and working principle of the third rotating device 421 are well-known technologies to those skilled in the art, so they will not be elaborated in detail here. Common third rotating device 421 includes a motor, a rotating cylinder, a rotating hydraulic cylinder, etc. In this embodiment, the third rotating device 421 preferably uses a motor.

[0054] Specifically, Figures 7 to 9 As shown, an arc-shaped rack plate 43 is provided on one side of the cleaning area close to the crushing pool 103; a push plate 423 is elastically slidably installed on the salvage plate 422 through a spring 4221. The traction assembly 424 includes a reel 4241 and a traction rope 4242; the reel 4241 is rotatably installed on the salvage plate 422 through a rotating shaft, and a driving gear 4243 is provided at one end of the rotating shaft extending out of the salvage plate 422; one end of the traction rope 4242 is connected to the reel 4241, and the other end is connected to the push plate 423. Fig. 9As shown, when the salvage plate 422 rotates to the point where the driving gear 4243 engages with the rack plate 43, the winding disk 4241 rotates the winding traction rope 4242 to drive the push plate 423 to slide along the salvage plate 422, thereby pushing the salvaged plastic bottle 01 to move toward the crushing pool 103; after the salvage plate 422 passes over the rack plate 43, the push plate 423 is reset under the elastic force of the spring 4221.
