Abstract
Description
Technical Field
[0001] The present invention generally relates to the field of plastic recycling, and in particular to a device for recycling waste plastic products. Background Art
[0002] Plastic waste refers to discarded plastic products, including various plastic containers, packaging materials, plastic films, plastic fibers, etc. These plastic wastes have many negative impacts on the environment and ecosystem. After use, plastic products are usually difficult to decompose naturally, and plastic waste needs to be recycled. Reusable plastic materials can be reshaped and reused, and unusable plastics are disposed of by landfill. The recovery of plastic waste usually starts with crushing the plastic products and then collecting the plastic particles.
[0003] The plastic recycling device before the improvement includes a crushing box, two crushing wheels are arranged at the bottom of the crushing box, and a driving assembly for driving the two crushing wheels to rotate relative to each other is arranged outside the crushing box. After the plastic products are put into the crushing box, due to the light weight of the plastic products, it is difficult to be crushed by the hinge force of the two crushing wheels by their own gravity, thereby affecting the overall plastic crushing operation. Summary of the invention
[0004] According to the present invention, in view of the problems existing in the above-mentioned prior art, a plastic product waste recycling device is provided, comprising: a crushing box, which is supported on the ground, and is provided with an inlet on the top and an outlet on the bottom; two crushing wheels are provided, which are located in the outlet area of the crushing box, and the two ends are rotatably connected inside the crushing box; a first driving component is fixed on one side of the crushing box, and is used to drive the two crushing wheels to rotate in relative directions to crush the plastic products; an extrusion cylinder, which is horizontally assumed inside the crushing box and is located above the two crushing wheels, leaving a feeding space between the extrusion cylinder and the crushing wheels; a second driving component is fixed above the extrusion cylinder, and is used to drive the extrusion cylinder to rotate about its own central axis to guide the waste to the feeding space between the extrusion cylinder and the crushing wheels. With the above technical features, plastic waste is put into the feed end of the crushing box. As the extrusion cylinder rotates, it guides and conveys the plastic waste, driving the plastic waste through the space between the extrusion cylinder and the crushing wheel and into between the two crushing wheels. Since the extrusion cylinder is located above the two crushing wheels, the activity space of the plastic waste is limited, the contact frequency between the plastic waste and the crushing area of the crushing wheel is increased, and the crushing efficiency is improved.
[0005] In some embodiments, it also includes: the extrusion barrel is a hollow structure with openings at both ends, a plurality of rows of material-diverting pieces are arranged on the outer peripheral surface of the extrusion barrel, an extension assembly is arranged inside the extrusion barrel to drive each material-diverting piece to slide away from the extrusion barrel; and a first limit barrel is arranged to cooperate with the extension assembly to drive the material-diverting piece to slide. Since the first limit barrel is located inside the extrusion barrel and does not rotate with the rotation of the extrusion barrel, the extrusion barrel is set as a hollow structure with openings at both ends to meet the installation of the first limit barrel and the rotation of the extrusion barrel. By controlling the fixed position of the first limit barrel, the extension assembly is linked to realize the extension of the material-diverting piece and to dig the plastic waste on the surrounding side.
[0006] In some embodiments, the extension assembly includes a slide bar, which is arranged along the radial direction of the extrusion barrel, one end of which passes through the outer wall of the extrusion barrel and is fixedly connected to the material-dispensing member; a stopper, which is fixed to the other end of the slide bar; and an elastic member, which is sleeved on the slide bar, one end of which abuts against the inner wall of the extrusion barrel and the other end of which abuts against the stopper. Thus, when the stopper is subjected to external force, the slide bar and the extrusion barrel are driven to slide, and the material-dispensing member is moved away from the extrusion barrel, thereby displacing the plastic waste on the peripheral side, thereby improving the efficiency of the waste entering the space between the extrusion barrel and the crushing wheel.
[0007] In some embodiments, the first limit barrel is mounted inside the extrusion barrel and is parallel to the axis of the extrusion barrel; the first limit barrel is arranged near the feeding side of the crushing box, and is used to abut against the limit block to drive the slide bar and the extrusion barrel to slide. Therefore, as the extrusion barrel rotates, the limit block rotates to the area on the feeding side, and the first limit barrel squeezes the limit block, driving the slide bar and the extrusion barrel to slide, so that the material-pickup piece extends out of the peripheral side of the extrusion barrel, and achieves the effect of prying the plastic waste, thereby improving the efficiency of plastic waste discharge.
[0008] In some embodiments, a second limiting barrel is provided inside the extrusion barrel, which is mounted inside the extrusion barrel and parallel to the axis of the extrusion barrel; the second limiting barrel is provided near the bottom area of the extrusion barrel, and is used to abut against the limiting block to drive the slide bar to slide with the extrusion barrel in the space between the two crushing wheels. Therefore, as the extrusion barrel rotates, the limiting block is pushed by the limiting position of the second limiting barrel, driving the material-diverting member below to extend out of the outer area of the extrusion barrel, thereby squeezing the plastic waste between the two crushing wheels, further improving the crushing efficiency of the plastic waste.
[0009] In some embodiments, the extrusion cylinder is erected through a first frame, the first frame includes two arc-shaped guide rails, which are symmetrically arranged on the upper edge of the extrusion cylinder, and the upper edge of the extrusion cylinder is located in the arc-shaped guide rails; two support rods are symmetrically arranged on both sides of the extrusion cylinder, vertically arranged, and one end is fixedly connected to the arc-shaped guide rails; a support plate is horizontally arranged above the extrusion cylinder and fixedly connected to the other ends of the two support rods; the first limiting barrel and the second limiting barrel are fixed to the arc-shaped guide rails. As a result, the arc-shaped guide rails not only support the extrusion cylinder, but also satisfy the relative rotation of the arc-shaped guide rails and the extrusion cylinder. Since the first limiting barrel and the second limiting barrel are supported, they can be independently fixed to the support plate, and while satisfying the normal rotation of the extrusion cylinder, the push of the shifting block can also be realized.
[0010] In some embodiments, the second driving assembly includes an annular rack coaxially arranged with the extrusion barrel and fixed to the outer peripheral side of the extrusion barrel; a first gear meshing with the annular rack; and a first motor, whose output shaft is coaxially fixed with the first gear and whose main body is fixed to the support rod. Thus, the active rotation of the extrusion barrel is achieved through the meshing of the first gear and the annular rack.
[0011] In some embodiments, a second frame is fixed above the crushing box, and the second frame is provided with two limit plates extending therefrom. The limit plates are symmetrically arranged on both sides of the extrusion barrel, and each of the support rods is penetrated by the limit plates on the same side and is slidably connected with the limit plates; a compression spring is sleeved on the support rod, and one end of the compression spring abuts against the limit plate, and the other end abuts against the support plate. If a large amount of plastic waste is fed, waste will accumulate in the space between the two crushing wheels. In order to ensure the safe use of the parts of each mechanism, through the arrangement of the compression spring, when the extrusion force between the plastic waste is greater than the elastic force of the compression spring, the extrusion barrel will be driven to move upward along the direction of the support rod, thereby avoiding obstacles and reducing the occurrence of component damage.
[0012] It should be understood that the contents described in the summary of the invention are not intended to limit the key or important features of the embodiments of the present disclosure, nor are they intended to limit the scope of the present disclosure.

DETAILED DESCRIPTION
[0015] Hereinafter, preferred embodiments (or implementation modes) of the present invention will be described in detail with reference to the accompanying drawings.
[0016] refer to Figure 1-Figure 4 A plastic product waste recycling device of the present invention is described.

[0018] Figure 2 FIG. 1 is a schematic diagram showing the structure of a crushing device 3 in a plastic waste recycling device provided by an embodiment of the present invention. Figure 2As shown, the crushing device 3 includes two horizontally arranged crushing wheels 31 located at the bottom of the crushing box 1, each crushing wheel 31 is composed of a plurality of coaxially spaced roller cutters. When the two crushing wheels 31 are arranged horizontally, the roller cutters on each crushing wheel 31 are arranged in a staggered manner, so that when they rotate in opposite directions, the plastic waste can be sheared. Each crushing wheel 31 is coaxially provided with a second gear 32, and the two second gears 32 are meshed with each other, so that the two crushing wheels 31 rotate in opposite directions. One of the second gears 32 is also provided with a power member (not shown in the figure), which can be coaxially arranged on one side of one of the second gears 32, and its output shaft is coaxially fixed with the second gear 32; the power member can also transmit power to one of the second gears 32 through a belt or chain, and drive the two second gears 32 to mesh and rotate.
[0019] Figure 3 FIG. 4 is a schematic diagram showing a support structure of an extrusion cylinder 4 in a plastic product recycling device provided by an embodiment of the present invention. Figure 3 As shown, an extrusion cylinder 4 is horizontally arranged inside the crushing box 1, and the axial direction of the extrusion cylinder 4 is parallel to the axial direction of the crushing wheel 31. The extrusion cylinder 4 is located in the top area of the crushing box 1, and there is a space between the extrusion cylinder 4 and the crushing wheel 31, so that when the extrusion cylinder 4 rotates, the input plastic waste can be introduced into the space between the extrusion roller and the crushing wheel 31. The extrusion cylinder 4 is erected by a first frame 41, wherein the first frame 41 includes a horizontally arranged support plate 411, and support rods 412 vertically arranged at both ends of the support plate 411, one end of the support rod 412 is fixedly connected to the end of the support plate 411, and the other end of the support plate 411 is fixedly connected to an arc guide rail 413, and the curvature of the arc guide rail 413 is the same as the arc of the extrusion cylinder 4, so that the top contour of the extrusion cylinder 4 is located inside the arc guide rail 413, and the extrusion cylinder 4 is slidingly connected to the arc guide rail 413, and the arc side of the arc guide rail 413 in contact with the extrusion cylinder 4 is provided with a plurality of beads rotatably connected to the inner wall of the arc guide rail 413, thereby reducing the friction between the arc guide rail 413 and the extrusion cylinder 4.
[0020] A second driving assembly 42 is arranged above the extrusion roller to drive the extrusion roller to rotate around its own central axis. The second driving assembly 42 includes an annular rack 421 arranged around the circumference of the extrusion cylinder 4, and the annular rack 421 is coaxially fixed to the extrusion cylinder 4; a first motor 422 is also arranged horizontally above the extrusion cylinder 4, and the first motor 422 is fixed to the support rod 412; a first gear 423 is coaxially fixed to the output shaft of the first motor 422, and the first gear 423 is meshed with the annular rack 421, and the first motor 422 drives the first gear 423, and the meshing of the first gear 423 and the annular rack 421 drives the extrusion cylinder 4 to rotate around its own central axis.
[0021] The first frame 41 is connected to the crushing box 1 through the second frame 43. The second frame 43 includes two columns 431. The columns 431 are relatively arranged on both sides of the crushing box 1. They are vertically arranged, and the lower ends are fixedly connected to the crushing box 1. A limit plate 432 is horizontally arranged on the upper ends. The support rods 412 of the first frame 41 are vertically penetrated by corresponding limit plates 432 and are slidably connected to the limit plates 432. A compression spring 433 is sleeved on each support rod 412. One end of the compression spring 433 abuts against one side of the limit plate 432, and the other end of the compression spring 433 abuts against the support plate 411, thereby achieving the purpose of indirectly setting up the crushing box 1 on the extrusion cylinder 4.
[0022] Figure 4 The longitudinal cross-sectional view of an extrusion barrel 4 in a plastic recycling device for plastic products provided by an embodiment of the present invention is shown. In order to improve the feeding efficiency of plastic waste, a material-dispensing device is provided on the circumference of the extrusion barrel 4, and the material-dispensing device includes material-dispensing members 5 distributed on the outer circumference of the extrusion barrel 4. The material-dispensing members 5 are provided in multiple groups, each group of material-dispensing members 5 includes at least three, and are arranged at intervals along the length direction of the extrusion barrel 4, and the multiple groups of material-dispensing members 5 are uniformly distributed around the outer circumference of the extrusion barrel 4; each material-dispensing member 5 is also connected to an extension component 51 that drives the material-dispensing member 5 to move away from the center of the extrusion barrel 4; and a first limiting barrel 52 that controls the extension of the extension component 51 is also provided inside the extrusion barrel 4.
[0023] The material-dispensing member 5 can be a block with a triangular cross section, and its three edges are smoothly rounded, so that when the material-dispensing member 5 is displaced, it can guide the plastic waste on the surrounding side. The extension component 51 is located inside the extrusion cylinder 4, and includes a slide bar 511, which is distributed along the radial direction of the extrusion cylinder 4, one end of which penetrates the extrusion cylinder 4 and is fixedly connected to the material-dispensing member 5, and the other end is fixedly connected with a limit block 512, and the side of the limit block 512 away from the slide bar 511 is set as an arc surface to reduce the friction force of contact with foreign objects, so as to facilitate the sliding of the slide bar 511; the slide bar 511 is also sleeved with a first spring 513, one end of the first spring 513 abuts against the inner wall of the extrusion cylinder 4, and the other end abuts against the limit block 512, so that when the extension component 51 is in the initial state, the slide bar 511 is received into the extrusion cylinder 4 under the elastic force of the first spring 513. The diameter of the first limiting barrel 52 is smaller than that of the extrusion cylinder 4. It is located inside the extrusion cylinder 4 and is arranged close to the feeding direction of the crushing box 1. There is a space between the inner wall of the extrusion cylinder 4, and the axis of the extrusion cylinder 4 is parallel to the axis of the first limiting barrel 52. First connecting parts extend from both ends of the first limiting barrel 52, and the other end of the first connecting part extends upward and is fixed on the arc guide rail 413, so that the first limiting barrel 52 is mounted inside the extrusion cylinder 4.
[0024] When the extrusion cylinder 4 rotates, the limit block 512 rotates with it and abuts against the outer peripheral surface of the first limit barrel 52. Since the limit block 512 and the first limit barrel 52 are both arc-shaped profiles, the limit block 512 is squeezed, driving the sliding rod 511 and the extrusion cylinder 4 to slide, so that the material-pickup member 5 is displaced away from the center of the extrusion cylinder 4. Since the first limit barrel 52 is located on the side of the feeding direction of the crushing box 1, as the plastic waste is put in, the protruding material-pickup member 5 follows the rotation of the extrusion cylinder 4 and drives the plastic waste to move to the bottom space, thereby accelerating the feeding efficiency of the plastic waste. Due to the positional relationship of the first limit barrel 52, as it approaches the crushing wheel 31, the limit block 512 is separated from the abutment with the first limit barrel 52, and under the action of the first spring 513, it drives the sliding rod 511 to move toward the internal space of the extrusion cylinder 4, and moves the material-pickup member 5 to the peripheral side of the extrusion cylinder 4, thereby avoiding interference with the crushing wheel 31.
[0025] In order to improve the crushing efficiency of the two crushing wheels 31 on the plastic waste, a second limiting barrel 53 is also horizontally arranged inside the extrusion barrel 4, the center line of the second limiting barrel 53 is parallel to the axis of the extrusion barrel 4, and the second limiting barrel 53 is located directly above the center of the two crushing wheels 31 and a gap is left between the inner wall of the extrusion barrel 4. Second connecting members are also arranged at both ends of the second limiting barrel 53, and the second connecting members extend upward and are fixed to the arc guide rail 413. The cross-section of the second limiting barrel 53 is an isosceles triangle, and its three edges are arranged as cambered surfaces. When the extrusion cylinder 4 rotates, the limiting block 512 will abut against the inclined surface of the second limiting barrel 53 as it rotates, and the sliding rod 511 and the extrusion cylinder 4 are guided by the inclined surface to slide, and the material-pickup member 5 is driven to move away from the extrusion cylinder 4. Due to the position of the second limiting barrel 53, the material-pickup member 5 will not touch the contour of the crushing wheel 31 even when it is moved to the farthest end, and the material-pickup member 5 is located in the space between the two crushing wheels 31 and extends out, thereby squeezing the plastic waste, accelerating the plastic material to enter the crushing space between the two crushing wheels 31, and improving the crushing efficiency of the plastic waste.
[0026] Due to the setting of the material-discharging device, the feeding efficiency of the plastic waste is accelerated, so that more uncrushed plastic materials remain in the space between the extrusion cylinder 4 and the two crushing wheels 31. Due to the sliding connection structure of the first frame 41 and the second frame 43, the stress damage to the material-discharging device caused by the accumulation of plastic waste can be avoided. Therefore, when the volume of the plastic waste is large or the accumulation is large, it will drive the extrusion cylinder 4 to move upward and drive the compression spring 433 to be elastically compressed to ensure the safe use of the material-discharging device.
