[0023] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative work fall within the scope of the present application.
[0024] In the description of the present application, it should be understood that the terms "upper", "lower", "front", "back", "left", "right", "top", "bottom", "inner", "outer" and the like indicate the orientation or positional relationship based on the orientation or positional relationship shown in the drawings, and are only for the convenience of describing the present application and simplifying the description, and do not indicate or imply that the devices or elements referred to must have a particular orientation, be constructed and operated in a particular orientation, and therefore cannot be understood as a limitation on the present application.
[0025] Please refer to Figure 1 and Figure 2 A kind of plastic particle automatic sorting and recycling equipment, similar to prior art device, the equipment is composed of multiple parallelly arranged material collecting tanks 3, these material collecting tanks 3 are specially used to load plastic particles of various particle sizes.
[0026] In addition, the upper side of each material collecting tank 3 is equipped with a coaxially fixed sorting ring 1, and these sorting rings 1 have special design.
[0027] Each sorting ring 1 is designed with multiple through holes, and the diameters of these through holes are different due to the sorting ring 1. Moreover, the diameters of the through holes on multiple sorting rings 1 arranged along the central axis direction of the sorting ring 1 show a decreasing trend. This design cleverly uses the through holes to achieve effective filtration and separation of plastic particles of different particle sizes.
[0028] It is worth noting that in the collection of multiple sorting rings 1, one end is an open structure, and the other end is a closed structure. Among them, the open structure can be used as a feed inlet.
[0029] Therefore, the diameter of the through hole closer to the feed inlet should be smaller to ensure that the through holes of different diameters can gradually separate the plastic particles, thereby achieving the purpose of accurate sorting.
[0030] It needs to be particularly pointed out that in actual application, each sorting ring 1 presents trapezoidal structure in vertical plane projection, and the diameters of the plurality of sorting rings 1 also present a decreasing state (the smaller the diameter of the sorting ring 1 closer to the feeding port). The design makes the inner cavity of the sorting ring 1 collection body inclined, and when the sorting ring 1 rotates synchronously, the inclined surface and the gravity jointly act to promote the plastic particles to automatically move downward and leftward in the sorting ring 1, so as to realize rolling and sorting.
[0031] Please refer to Figure 1 and Figure 3 Unlike existing technical devices, the plurality of sorting rings 1 are collectively configured below with a longitudinal displacement mechanism. The longitudinal displacement mechanism forces the sorting ring 1 to deform, effectively preventing the plastic particles from being stuck in the through hole.
[0032] Specifically, the longitudinal displacement mechanism includes a driving motor 2. And, as shown in Figure 1 and Figure 4 , a support frame is arranged on the output shaft of the driving motor 2 to help the driving motor 2 to remain stable.
[0033] It needs to be particularly pointed out that, as shown in Figure 3 , a corresponding mounting hole is formed below each collection tank 3, and the mounting hole is sleeved outside the output shaft of the driving motor 2. At this time, the collection tank 3 is rotatably connected with the output shaft of the driving motor 2 through a bearing, so as to ensure that the position of the collection tank 3 is fixed and supported by the output shaft of the driving motor 2 (the lower end of the collection tank 3 is generally placed on the ground or connected with the rest of the mechanism, at this time, in cooperation with its own gravity, only the position needs to be constrained to ensure that it does not deviate in position during use).
[0034] It needs to be emphasized that, as shown in Figure 1 and Figure 2 , in actual application, the two axial ends of the collection body composed of the plurality of sorting rings 1 are respectively provided with a positioning frame, which supports and limits the collection body composed of the plurality of sorting rings 1.
[0035] The axial end of the collection body is provided with a driven gear which is engaged with the lower driving gear, and the rotation of the driving gear drives the sorting ring 1 to rotate synchronously.
[0036] Therefore, the driving gear of the device is key-connected with the output shaft of the driving motor 2, so that the automatic rotation of the plurality of driving rings can be realized.
[0037] Please refer to Figure 3 and Figure 4 , specifically, the longitudinal displacement mechanism further includes a driving wheel 5, the driving wheel 5 is sleeved outside the output shaft of the driving motor 2, and the output shaft of the driving motor 2 is key-connected with the driving wheel 5, so that the device can drive the driving wheel 5 to rotate through the driving motor 2.
[0038] Further, the side end of each driving wheel 5 is fixedly connected with a plurality of push rods 6. The push rods 6 are arranged equidistantly around the central axis of the driving wheel 5. At this time, if the distance between the upper end of each driving wheel 5 and the corresponding sorting ring 1 is less than the length of the push rod 6, the push rod 6 can effectively push the sorting ring 1 by interfering with the travel between the push rod 6 and the sorting ring 1 when the driving wheel 5 rotates, thereby causing the active deformation of the sorting ring 1.
[0039] As shown in Figure 6 , further, the device restricts each push rod 6 to include a sleeve 602, and the sleeve 602 is nested with an inner rod 601.
[0040] Meanwhile, a compression spring 603 is coaxially arranged in the sleeve 602, and the two axial ends of the compression spring 603 abut against the corresponding sleeve 602 and inner rod 601, so that the inner rod 601 has a movement trend away from the central axis of the driving wheel 5. This can utilize the active deformation of the inner rod 601 to avoid large travel conflicts between the inner rod 601 and the sorting ring 1, thereby avoiding damage to the device.
[0041] Further, in order to reduce the frictional resistance between the inner rod 601 and the sorting ring 1 (prolong the service life of the device), and to ensure that the inner rod 601 can actively break through the elastic force of the compression spring 603 and enter the inside of the sleeve 602, the device rotates a roller 7 on the side of each push rod 6 away from the corresponding driving wheel 5. By restricting the central axis of the roller 7 to be parallel to the central axis of the sorting ring 1, rolling friction between the roller 7 and the sorting ring 1 can be achieved, thereby avoiding sliding friction between the inner rod 601 and the sorting ring 1. The circular surfaces of the roller 7 and the sorting ring 1 match each other, which can enhance the component of the force acting on the roller 7 by the sorting ring 1 in the direction of the central axis of the inner rod 601, and ensure that the inner rod 601 can overcome the elastic force of the compression spring 603.
[0042] It should be emphasized that, although the device only shows simple sliding friction between the inner rod 601 and the sleeve 602 in Figure 6 , and they lack corresponding limiting mechanisms, in practice, in order to ensure that the inner rod 601 can only slide a limited distance relative to the sleeve 602 and avoid the inner rod 601 from coming out of the sleeve 602, there must be corresponding limiting mechanisms between them (using a sliding rod fixed on the side end of the inner rod 601, and a sliding groove is formed on the sleeve 602 for the sliding rod), or there must be enough sliding friction to ensure that the inner rod 601 will not separate from the sleeve 602 during daily use.
[0043] As shown in Figure 5 , further, the device restricts the lengths of the push rods 6 adjacent to the side end of each driving wheel 5 to be inconsistent. This design is to allow the push rods 6 to produce different displacement effects when pushing the sorting ring 1.
[0044] Specifically, the push rod 6 at each side end of the driving wheel 5 is formed in a wavy structure away from the end of the driving wheel 5, which can intensify the deformation of the side end of the sorting ring 1 and make it more irregular, thereby effectively preventing the plastic particles from falling off the through hole.
[0045] As shown in Figure 1 and Figure 2 Further, the device restricts each sorting ring 1 to be composed of metal filaments woven together, and the through hole is actually the gap between the metal filaments, so that the active deformation of the sorting ring 1 can be more facilitated by using the flexible characteristics of the metal filaments themselves, and the large stroke conflict between the sorting ring 1 and the push rod 6 can be avoided.
[0046] It is worth noting that, in order to ensure that the sorted plastic particles accurately fall into the collection tank 3, the device coaxially and fixedly connects the transfer ring 4 between adjacent sorting rings 1, and the longitudinal displacement mechanism is arranged below the transfer ring 4, so that the through hole is completely corresponding to the position of the collection tank 3.
[0047] Correspondingly, the transfer ring 4 is made of flexible metal products and has the ability of flexible deformation. By limiting the wall thickness, the transfer ring 4 maintains a proper degree of deformability.
[0048] In the actual application process of the utility model:
[0049] The design and function of the sorting ring 1 are embodied as follows: The sorting ring 1 is provided with through holes with different diameters, which are arranged along the central axis direction and have a decreasing diameter, aiming to realize the filtration and separation of plastic particles with different particle sizes. The open structure of the sorting ring 1 serves as a feed inlet, and the closed structure is responsible for collecting the sorted plastic particles.
[0050] The function of the longitudinal displacement mechanism is realized as follows: The longitudinal displacement mechanism cooperates with the push rod 6 and the driving motor 2 to force the sorting ring 1 to deform, thereby effectively preventing the plastic particles from being stuck in the through hole. The output shaft of the driving motor 2 is key-connected with the driving wheel 5, and the rotation of the driving wheel 5 in turn drives the sorting ring 1 to deform, so as to realize the rolling and sorting of the plastic particles.
[0051] The structure design of the transfer ring 4: The transfer ring 4 is arranged between adjacent sorting rings 1 and is made of flexible metal material, which ensures that it has sufficient deformability. The transfer ring 4 is designed to accurately correspond to the position of the through hole and the collection tank 3, so as to ensure that the sorted plastic particles accurately fall into the predetermined tank.
[0052] Although the embodiments of the utility model have been shown and described, it can be understood by those skilled in the art that various changes, modifications, replacements and variations can be made to these embodiments without departing from the principles and spirits of the utility model, and the scope of the utility model is defined by the appended claims and their equivalents.
