Technical Field

[0001] This utility model relates to the field of plastic recycling technology, and in particular to a waste plastic sorting and separation device. Background Art

[0002] Plastics are polymers made from monomers through addition or condensation polymerization. They have moderate resistance to deformation, falling between fibers and rubber. They are composed of synthetic resins and additives such as fillers, plasticizers, stabilizers, lubricants, and colorants. Plastic products are now widely used in various industries. Waste plastics can be recycled and reused, reducing resource waste.

[0003] The existing Chinese patent publication number CN218111376U describes a sorting and separation device for waste plastics. According to the description, the device has a relatively closed structure. This structure is very prone to causing waste plastics to get stuck during use, which not only affects the separation work of the device, but also increases the difficulty of cleaning and maintenance later.

[0004] Therefore, it is necessary to provide a new waste plastic sorting and separation device to solve the above-mentioned technical problems. Utility Model Content

[0009] Preferably, the support assembly further includes an adapter frame, which is slidably installed inside the outer fixed frame. A telescopic rod is provided between the adapter frame and the inner support frame. The top end of the telescopic rod is fixedly connected to the inner top of the inner support frame, and the end of the telescopic rod is fixedly connected to the interior of the adapter frame.

[0010] Preferably, the adapter frame has symmetrically distributed springs on both sides inside, and the ends of the springs on the same side are provided with the same fixedly connected support block, and the support block is fixedly installed on the top of the outer fixed frame.

[0011] Preferably, a mounting bracket a is fixedly connected to one side of the top of the outer fixed frame, and an elliptical roller a is rotatably connected inside the mounting bracket a. The mounting bracket a is equipped with a motor that drives the elliptical roller a, and the outer wall of the elliptical roller a abuts against and is slidably connected to the outer wall of the adapter frame.

[0012] Preferably, the adapter frame has an internal mounting frame b, and the mounting frame b has an internally mounted rotatably connected elliptical roller b. The mounting frame b is equipped with a motor that drives the elliptical roller b, and the outer wall of the elliptical roller b abuts against and is slidably connected to the inner top of the inner support frame.

[0024] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0025] The specific implementation of this utility model will be described in detail below with reference to specific embodiments.

[0026] Please see Figures 1 to 5 The present invention provides a waste plastic sorting and separation device, which includes: a base plate 1, a feeding hopper 2 on one side of the top of the base plate 1, a movably connected conveyor belt 4 above the top of the base plate 1, and a support assembly 3 for mounting the conveyor belt 4 on the top of the base plate 1.

[0027] In the embodiments of this utility model, please refer to Figures 1 to 5 The conveyor belt 4 is a hollow mesh chain structure. Several evenly distributed scraping plates 42 are provided on the conveyor belt 4. The outer wall of the scraping plate 42 is an arc surface structure. Baffles 41 are provided on both sides of the conveyor belt 4, and an arc groove 21 is provided on the side of the end of the hopper 2 near the conveyor belt 4.

[0028] It should be noted that: since the outer wall of the scraper 42 is an arc-shaped structure, and the hopper 2 is provided with an arc-shaped groove 21 on the side near the conveyor belt 4, the arc-shaped groove 21 can facilitate the storage of waste plastic when feeding through the hopper 2, so that the rotating arc-shaped scraper 42 can scrape the waste plastic more smoothly, and the conveyor belt 4 can stably move the waste plastic. At the same time, since the waste component is a hollow mesh chain structure, the hollow mesh chain structure can facilitate the falling of particulate impurities on the waste plastic during the rotation of the conveyor belt 4.

[0029] Meanwhile, due to the open structure of the conveyor, the phenomenon of waste plastic clogging inside the device can be reduced during use, and it is also easier for staff to clean the mesh chain holes used to separate particulate impurities from the plastic later. At the same time, the circulating conveyor belt 4 can also enable the device to operate continuously without stopping, thus improving the user experience of the device.

[0030] In the embodiments of this utility model, please refer to Figures 1 to 5 The support assembly 3 includes an outer fixing frame 31 and an inner support frame 32. The outer fixing frame 31 is mounted on the base plate 1, and the inner support frame 32 is movably installed inside the outer fixing frame 31. The bottom end of the inner support frame 32 is fixedly connected to the top of the baffle 41. The support assembly 3 also includes a transition frame 33, which is slidably installed inside the outer fixing frame 31. A telescopic rod 35 is provided between the transition frame 33 and the inner support frame 32. The top end of the telescopic rod 35 is fixedly connected to the inner top of the inner support frame 32, and the end of the telescopic rod 35 is fixedly connected to the inside of the transition frame 33. Symmetrically distributed springs 331 are provided on both sides inside the transition frame 33, and the ends of the springs 331 on the same side are provided with the same fixedly connected support block 3. 32, and the support block 332 is fixedly installed on the top of the outer fixed frame 31. A fixedly connected mounting frame a34 is mounted on one side of the top of the outer fixed frame 31. An elliptical roller a341 is rotatably connected inside the mounting frame a34. A motor for driving the elliptical roller a341 is mounted on the mounting frame a34. The outer wall of the elliptical roller a341 abuts against and is slidably connected to the outer wall of the adapter frame 33. A mounting frame b36 is mounted inside the adapter frame 33. An elliptical roller b361 is rotatably connected inside the mounting frame b36. A motor for driving the elliptical roller b361 is mounted on the mounting frame b36. The outer wall of the elliptical roller b361 abuts against and is slidably connected to the inner top of the inner support frame 32.

[0031] It should be noted that, through the setting of spring 331, when the relatively shorter side wall of the elliptical roller a341 is opposite to the outer wall of the transfer frame 33 during the rotation of the motor, spring 331 can drive the transfer frame 33 to reset and move by its own force. Therefore, the combination of spring 331 and elliptical roller a341 can make the conveyor belt 4 move back and forth in a stable horizontal direction in the later stage. Since the elliptical roller b361 is set below the inner support frame 32, and a telescopic rod 35 is erected between the inner support frame 32 and the transfer frame 33, when the relatively shorter side wall of the elliptical roller b361 rotates to be opposite to the inner top of the inner support frame 32, the inner support frame 32 can squeeze the telescopic rod 35 down by its own gravity, so that the inner support frame 32 can drive the conveyor belt 4 to move back and forth in a vertical direction. Therefore, through the combination of the two, the vibration separation effect of the conveyor belt 4 on waste plastics during operation can be improved.

[0032] In the embodiments of this utility model, please refer to Figures 1 to 5 A placement slot 11 is provided below the top conveyor belt 4 of the base plate 1, and a collection box 5 is placed inside the placement slot 11.

[0033] It should be noted that the placement slot 11 allows the collection box 5 to be positioned, making it easier for staff to place and position the collected particles after cleaning them.

[0034] In the embodiments of this utility model, please refer to Figures 1 to 5 The outer fixed frame 31 has a lower hopper 6 mounted on the side away from the upper hopper 2, and the top of the lower hopper 6 does not contact the bottom of the scraper plate 42.

[0035] It should be noted that by setting the feeding hopper 6 below the scraper plate 42, the feeding hopper 6 can avoid obstructing the scraper plate 42 when the scraper plate 42 rotates with the conveyor belt 4, thus allowing the scraper plate 42 to scrape the waste components smoothly. At the same time, since the feeding is in an inclined state, the separated waste plastic can slide smoothly downwards after falling onto the feeding hopper 6.

[0036] The working principle of the waste plastic sorting and separation equipment provided by this utility model is as follows:

[0037] When using this waste plastic sorting and separation equipment, the staff can add the waste plastic to be separated into the upper hopper 2. At this time, the working conveyor belt 4 can drive the external scraper 42 to rotate synchronously.

[0038] When the scraper plate 42 rotates into the arc groove 21, it can grab the waste plastic inside the hopper 2 and flip it over to the top of the conveyor belt 4. At the same time, the rotating elliptical roller a341 in the support assembly 3 can squeeze the transfer frame 33. Since the outer diameter of the elliptical roller a341 is different, the elliptical roller a341 can cause the transfer frame 33 to drive the inner support frame 32 and the conveyor belt 4 to swing back and forth in the horizontal direction through the combination of the force of the spring 331 in the transfer frame 33 during the rotation. At the same time, the elliptical roller a341 can drive the inner support frame 32 and the conveyor belt 4 to swing back and forth in the set direction through the combination of gravity of the inner support frame 32 and the conveyor belt 4. Then, the waste plastic conveyed above it is vibrated by the conveyor belt 4. At the same time, since the conveyor belt 4 is a hollow mesh chain structure, when the waste plastic is subjected to vibration, the particulate impurities on its outer wall can fall down into the collection frame 5 through the hollow mesh chain.

[0039] As the conveyor belt 4 continues to drive, it transports the waste plastic above to one end near the hopper 6. When the scraper 42 on the conveyor belt 4 flips, the waste plastic falls onto the hopper 6 for unloading, thus realizing the cyclic operation of this device.

[0040] The circuits and controls involved in this utility model are all existing technologies, and will not be described in detail here.

[0041] The above are merely embodiments of this utility model and do not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the description and drawings of this utility model, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
