Description

Technical Field

[0001] The utility model relates to the technical field of material recycling, in particular to an automated ABS waste recycling and ingredient mixing system. Background Art

[0002] In the current ABS sheet production process, the shortcomings of waste recycling and batching systems are particularly significant, directly impacting production costs, resource utilization, and overall sheet quality. Existing technologies often rely on manual labor, which is not only inefficient but also prone to human error, limiting the recovery rate of scrap and substandard sheets. Waste comminution technology is relatively backward, lacking an efficient comminution mechanism. This results in uneven particle size in the pulverized waste, impacting the uniformity of the subsequent mixing stage and the performance of the recycled material. Furthermore, inefficient removal of impurities from the waste affects the purity of the recycled material, and thus the final quality of the sheet. During the batching and mixing stage, traditional batching systems often lack precise metering methods to ensure that new and recycled materials are precisely mixed in the desired ratio, potentially leading to inconsistent sheet properties. Mixer designs are often rudimentary, making it difficult to achieve uniform mixing of raw materials. This is particularly true when processing materials with varying particle sizes and shapes, which can lead to localized overheating and uneven mixing, impacting material properties. The lack of moisture control mechanisms is also a key issue. If the moisture content of the raw materials is not effectively managed, it can cause material agglomeration and impair extrusion performance. The design of recycled material extrusion dies also has limitations. The lack of independent recycled material extrusion channels and temperature control limits the utilization rate of recycled materials and the molding quality of the sheets. Faced with the current situation where domestic ABS resin technology is restricted by human factors and the continued growth of market demand, especially the pursuit of cost-effective and high-performance ABS sheets, the bottleneck of existing technology has become a key factor restricting the further development of the industry. Innovative automated waste recycling and ingredient mixing systems are urgently needed to improve production efficiency and reduce production costs while ensuring sheet quality and achieving efficient resource recycling, injecting new vitality into the ABS sheet production industry.

[0027] Example 1

[0028] See also Figure 1-5 The utility model provides a technical solution: an automated ABS waste recycling and ingredient mixing system, including a collecting port 1, a conveying device 2, a crushing device 3, a screening device 4 and a mixing device 5.

[0032] Specifically, the crushing device 3 includes a crushing chamber 301 and a crushing chamber 303. The crushing chamber 303 is fixedly installed on the lower surface of the front end of the crushing chamber 301, and the two are connected to each other. The upper end of the crushing chamber 301 is fixedly installed with a waste material injection port 302 connected to the interior thereof. A first screen 307 and a second screen 308 are fixedly installed in the crushing chamber 301. The second screen 308 is located below the first screen 307.

[0036] Specifically, a first material guide plate 311 is fixedly installed at the bottom of the crushing chamber 301 , and the lower end of the first material guide plate 311 is located in the crushing chamber 303 .

[0037] The crushed waste materials are guided more smoothly to the crushing chamber 303 by the first material guide plate 311 .

[0038] Specifically, the quantitative injection device connected to the new material injection port 505 is a loss-in-weight scale or a volumetric feeder.

[0039] The mixing of new and old materials can be precisely controlled according to the preset formula ratio through loss-in-weight scale or volumetric feeder

[0040] Specifically, humidity sensors are fixedly installed in the crushing device 3, the screening device 4 and the mixing device 5, and the humidity sensors are connected to an external host computer.

[0041] By connecting the humidity sensor to an external host computer, the moisture content of the raw materials can be effectively monitored and the drying process can be started when necessary to keep the raw materials in the best condition.

[0042] Specifically, an inclined guide block 406 is fixedly installed on the inner wall of the screening chamber 401 , and the inclined guide block 406 is located above the third screen 404 .

[0043] The oblique guide block 406 can more effectively cause the old material to fall into the optimal screening area of ​​the third screen 404 .

[0044] Working principle: When in use, the scraps and unqualified plates generated by the extruder and cutting equipment are guided to the conveying device 2 through the collecting port 1, and the conveying device 2 then guides the scraps and unqualified plates to the crushing device 3, and introduces them through the old material injection port 302, and then the first crushing blade 309 and the second crushing blade 310 effectively crush them to form old material particles. The old material particles are guided to the crushing cavity 303 of the crushing device 3, and then guided to the screening device 4 through the climbing pipe 305 and the spiral leaf rod. The screening device 4 screens again through the third screen 404 to effectively remove impurities. At the same time, the old material is guided to the mixing device 5, and the new material injection port 505 of the mixing device 5 introduces the new material. Under the action of the planetary stirring frame 504, the new material and the old material are effectively mixed and discharged to the outlet device.

[0045] Example 2: Optimized Blade Layout Design

[0046] This is achieved in the comminution device by increasing the number of blades, changing the blade arrangement, and introducing a staggered blade array. Specifically, multiple sets of first and second shafts are added between the first and second screens 307 and 308. Each set of shafts is equipped with multiple first and second comminution blades 309 and 310. These blades are arranged in a staggered pattern, meaning that the tips of one set of blades are staggered with the edges of the adjacent set, forming a continuous comminution zone.

[0047] Interaction with Other Components: The optimized blade layout closely coordinates with the first and second screens 307, 308, controlling the particle size of the crushed material through the gaps between the blades and the screens. Upon entering the crushing chamber 301, the material is first coarsely crushed by the first set of blades, then passes through the first screen 307 to the second set of blades for further crushing, and finally passes through the second screen 308 for final crushing. The spacing between each blade and screen stage is carefully designed based on the desired material size, ensuring the ideal particle size distribution during the crushing process.

[0048] Effect: Optimizing the blade layout significantly improves pulverization efficiency and quality. Material is pulverized multiple times in a continuous crushing zone, ensuring uniform particle size and improved pulverization efficiency. The staggered blade array reduces the possibility of material clogging the screen, while also reducing blade wear and extending blade life.

[0049] Example 3: Design of adding static mixing elements in the mixing chamber

[0050] Static mixing elements, such as propeller-shaped mixing blades 506 or labyrinth-type baffles 507, are added to the mixing chamber 501. These elements are fixedly mounted on the inner wall of the mixing chamber 501 and cooperate with the rotation direction of the planetary stirring frame 504 to form a complex flow path for the material.

[0051] The static mixing element works together with the planetary stirring frame 504. The rotation of the planetary stirring frame 504 drives the material to tumble in the mixing chamber 501, while the static mixing element guides the material to move along a specific path, thereby increasing the contact area between the materials and the number of mixing times.

[0052] Effect: Adding static mixing elements can significantly improve mixing efficiency and uniformity. The material undergoes multiple shearing and reorganization in the complex flow path. Even when processing materials of different particle sizes and forms, it can ensure good mixing effect, avoid local overheating or uneven mixing, and thus improve the quality and performance of the final product.
