Description

Technical Field

[0001] This utility model relates to the field of plastic masterbatch screening technology, and in particular to a conveying device for plastic masterbatch screening. Background Technology

[0002] In the production of plastic masterbatch, screening is a core process to ensure product quality. Its role is not only to accurately remove foreign impurities (such as metal scraps, unmelted lumps, etc.) from the raw materials, but also to achieve gradient gradation of particle size to meet the particle size requirements of different application scenarios.

[0003] In the prior art, a search revealed a Chinese patent disclosure entitled "A Conveying Device for Masterbatch Screening," application number "202321205394.5." This patent mainly includes a screening plate, comprising a first screening plate and a second screening plate. Both the first and second screening plates are provided with several sets of screening holes of different sizes, and each set of screening holes is preceded by a first blocking roller. The first screening plate performs preliminary screening of the masterbatch, and the second screening plate screens the masterbatch not screened by the first screening plate. The masterbatch screened by the second screening plate enters a conveying channel. The conveying channel is provided with secondary screening holes, which perform secondary screening of the masterbatch screened by the first screening plate. A baffle plate conveys the secondary-screened masterbatch into the conveying channel. A frame is used to mount the screening plate, the conveying channel, and the baffle plate. Although the aforementioned utility model employs a screening plate and conveying channel to perform multiple screenings of the masterbatch, with the screened masterbatch flowing into the conveying channel for transport, the overall structure is complex, the process is lengthy, and it occupies a large area due to the numerous screening components, including a first screening plate, a second screening plate, a third screening hole, a conveying channel, a first channel, a second channel, a fourth screening hole, a third channel, and a fifth screening hole. Furthermore, the numerous screening components increase the risk of screen clogging, potentially leading to frequent shutdowns for cleaning. Therefore, this utility model provides a conveying device for screening plastic masterbatch to solve the problems mentioned in the background art. Utility Model Content

[0024] This section will describe in detail the specific embodiments of the present utility model. The preferred embodiments of the present utility model are shown in the accompanying drawings. The purpose of the drawings is to supplement the textual description with graphics, so that people can intuitively and vividly understand each technical feature and the overall technical solution of the present utility model, but they should not be construed as limiting the scope of protection of the present utility model.

[0025] Reference Figure 1-4 This utility model discloses a conveying device for screening plastic masterbatch, comprising a base plate 1, a fixed column 2 fixedly mounted on the top of the base plate 1, and a screening assembly mounted on the fixed column 2. The screening assembly includes a first screen plate 3 fixed to the outside of the fixed column 2, a second screen plate 4 fixed to the outside of the fixed column 2 and located below the first screen plate 3, and a collection plate 5 fixed to the outside of the fixed column 2 and located below the second screen plate 4. The first screen plate 3, the second screen plate 4, and the collection plate 5 are all designed with a spiral structure. The top of the outer ring of the first screen plate 3, the second screen plate 4, and the collection plate 5 are all provided with a folded edge structure for blocking. The aperture of the first screen plate 3 is larger than that of the second screen plate 4.

[0026] Plastic masterbatch enters the first screen disc 3. The spiral structure of the first screen disc 3 and the second screen disc 4 ensures that the plastic masterbatch can fall freely and roll for step-by-step screening. Large masterbatch particles are discharged through the first screen disc 3, while small particles pass through the first screen disc 3 and enter the second screen disc 4 for secondary screening. Finally, the smallest and finest particles fall into the collection disc 5 to complete the screening process. Through the synergistic effect of the spiral screen discs and horizontal vibration, multi-stage screening and conveying are integrated, resulting in high screening efficiency, simple operation, and less screen clogging, making it highly practical.

[0027] The bottom of the base plate 1 is provided with a vibration assembly, which includes a base 12 located below the base plate 1, a plurality of springs 10 uniformly fixed between the base plate 1 and the base 12, and a vibration motor 11 fixed to the bottom of the base plate 1.

[0028] The vibrating motor 11 generates vibration, and the base plate 1 drives the screen plate to vibrate horizontally, so that the masterbatch rolls and is screened along the spiral channel, which facilitates the falling and screening of the masterbatch while ensuring the screening effect and improving the screening efficiency.

[0029] Multiple limiting frames 7 are fixed on the top sides of the first screen plate 3 and the second screen plate 4. A ball 13 is placed inside each limiting frame 7. During the vibrating screening process of the screen plate, the elastic ball is vibrated and impacts the surface of the screen plate, which helps to effectively clear the blocked screen holes and ensure good screening quality of the screen plate.

[0030] A fixing plate 8 is fixedly installed on the top of the fixing column 2. A hopper 9 is fixedly connected inside the fixing plate 8. The outlet of the hopper 9 is directly opposite the spiral starting end of the first screen plate 3.

[0031] The bottom ends of the first screen plate 3, the second screen plate 4, and the collection plate 5 are all fixedly connected with guide plates 6. The guide plates 6 are set to shorten from top to bottom to ensure that the screened plastic masterbatch can be discharged smoothly and facilitate classification and collection.

[0032] Sphere 13 is a flexible elastic sphere, which reduces the impact on the screen plate while ensuring free bouncing during vibration.

[0033] The first screen plate 3, the second screen plate 4, and the collection plate 5 are all made of highly wear-resistant materials. Materials such as stainless steel, polyurethane, or nylon can be selected to make the screen plates to resist the friction and impact of plastic masterbatch and extend the service life of the screen plates.

[0034] Working principle: Plastic masterbatch enters the first screen plate 3. The spiral structure of the first screen plate 3 and the second screen plate 4 ensures that the plastic masterbatch can fall freely and roll for step-by-step screening. Large particles of masterbatch are discharged through the first screen plate 3, while small particles pass through the first screen plate 3 and enter the second screen plate 4 for secondary screening. Finally, the smaller and finer particles fall into the collection plate 5 to complete the screening process.

[0035] At the same time, the vibrating motor 11 generates vibration, and the bottom plate 1 drives the screen plate to vibrate horizontally, so that the masterbatch rolls and screens along the spiral channel, which is conducive to the masterbatch falling and screening while ensuring the screening effect and improving screening efficiency.

[0036] Through the synergistic effect of the spiral screen disc and horizontal vibration, multi-stage screening and conveying are integrated, resulting in high screening efficiency, simple operation, simple overall structure, and small space occupation. At the same time, the elastic balls 13 are set to impact the surface of the screen disc by vibration, effectively clearing the blocked screen holes, making the screen less prone to clogging and highly practical.

[0037] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
