Description

Technical Field

[0001] This utility model relates to the field of screening device technology, specifically a screening device for the production of polyethylene filler masterbatch. Background Technology

[0002] Polyethylene filler masterbatch, as an innovative achievement in the field of polymer materials, is a new type of material that precisely fuses inorganic or organic fillers with polyethylene resin through a special process. As the application fields of polyethylene filler masterbatch continue to expand, the requirements for its quality indicators such as particle size uniformity and impurity content are becoming increasingly stringent. In the production process of polyethylene filler masterbatch, the screening process is crucial, and its effect directly affects product quality and production efficiency.

[0003] Traditional polyethylene filler masterbatch screening devices often use bolts for screen installation, which requires various tools, making the process cumbersome, time-consuming, and labor-intensive, potentially affecting production progress. Furthermore, masterbatch tends to adhere to the screen during screening, and if not cleaned promptly, it can clog the screen and affect screening efficiency. Traditional devices often require manual cleaning of the screen, increasing the workload for workers. Therefore, this paper proposes a screening device for polyethylene filler masterbatch production to address these issues. Utility Model Content

[0004] The purpose of this utility model is to provide a screening device for the production of polyethylene filler masterbatch. By setting up a connecting component, a T-shaped column and a cleaning component, it solves the problems of traditional polyethylene filler masterbatch screening devices, which often use bolts to fasten the screen during installation. Bolt installation requires multiple tools, which is cumbersome, time-consuming and labor-intensive, and can easily affect the production progress. In addition, masterbatch easily adheres to the screen during screening. If it is not cleaned in time, it will clog the screen and affect the screening effect. Traditional devices often require manual cleaning of the screen, which increases the workload of workers.

[0005] This utility model is achieved through the following technical solution:

[0006] This utility model is a screening device for the production of polyethylene filler masterbatch, including a vibrating screen, a screen mesh, a connecting assembly, and a cleaning assembly. Connecting grooves are provided on both side walls of the vibrating screen, and first limiting holes are provided on the connecting grooves. A second limiting hole corresponding to the first limiting hole is provided on the screen mesh. The connecting assembly is mounted on the vibrating screen and has a T-shaped post. The T-shaped post engages with the first and second limiting holes. After rotating 90°, the T-shaped post abuts against the screen mesh. The cleaning assembly is mounted on the vibrating screen and engages with the screen mesh.

[0007] Furthermore, the connecting assembly includes an L-shaped plate, a spring, and a pressing plate. The L-shaped plate is mounted on the vibrating screen and has a through hole. A T-shaped column slides into the through hole and is fitted with a circular plate. One end of the spring is mounted on the circular plate, and the other end of the spring is mounted on the vibrating screen. The pressing plate is mounted on the T-shaped column.

[0008] Furthermore, the cleaning assembly includes a cleaning brush, a rack plate, and a cross plate. The cleaning brush contacts the surface of the screen. Both ends of the cleaning brush are equipped with cylinders, and gears are mounted on the cylinders. There are two rack plates, which are mounted on connecting grooves. The gears mesh with the rack plates. One of the connecting grooves has a rectangular hole, and one of the cylinders slides into the rectangular hole. The end of one of the cylinders away from the cleaning brush is mounted to the power output shaft of the drive source. The cross plate is mounted on the vibrating screen and has a sliding groove, with the drive source sliding into the sliding groove.

[0009] Furthermore, the vibrating screen is equipped with a feed hopper, which has a funnel-shaped opening.

[0010] Furthermore, the vibrating screen is equipped with a first discharge frame and a second discharge frame. The first discharge frame is located directly below the screen mesh, and the second discharge frame is located at the opening of the screen mesh.

[0011] This utility model has the following beneficial effects:

[0012] 1. This utility model, by setting up a connecting component and a T-shaped column, allows the T-shaped column to rotate 90° and then come into contact with the screen, thereby completing the installation of the screen and the vibrating screen. This solves the problem that the screen of the traditional polyethylene filler masterbatch screening device is often fastened with bolts during installation. Bolt installation requires a variety of tools, which is cumbersome, time-consuming and labor-intensive, and can easily affect the production progress.

[0013] 2. This utility model, by setting up a cleaning component, starts a three-phase asynchronous motor, which drives the two cylinders and the cleaning brush to rotate via the power output shaft of the three-phase asynchronous motor. The cylinders drive the gears to roll on the rack plate, while simultaneously moving the three-phase asynchronous motor. This allows the cleaning brush to reciprocate and clean the screen, solving the problem that masterbatch easily adheres to the screen during screening, and if not cleaned in time, it will clog the screen and affect the screening effect. Traditional devices often require manual cleaning of the screen, which increases the workload of workers.

[0014] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Please see Figure 1-8 This utility model provides a technical solution: a screening device for the production of polyethylene filler masterbatch, including a vibrating screen 1, a screen 2, a connecting component 3 and a cleaning component 5. The vibrating screen 1 is composed of a screen frame, a vibrating motor, support legs, a shock absorption system and a control system. The screen 2 is made of stainless steel and has good wear resistance and corrosion resistance. This is an existing structure and will not be described in detail here.

[0026] The vibrating screen 1 has connecting grooves 101 on both sides of its side walls. The connecting grooves 101 have first limiting holes 102. The first limiting hole 102 consists of a round hole and two square holes. The round hole is located in the middle of the two square holes and is connected to each other. The screen 2 has a second limiting hole 201 corresponding to the first limiting hole 102. The connecting assembly 3 is set on the vibrating screen 1. The connecting assembly 3 is provided with a T-shaped column 4. The T-shaped column 4 cooperates with the first limiting hole 102 and the second limiting hole 201. After rotating 90°, the T-shaped column 4 abuts against the screen 2.

[0027] The connecting assembly 3 includes an L-shaped plate 301, a spring 304, and a pressing plate 305. The L-shaped plate 301 is bolted to the outer wall of the vibrating screen 1. A through hole 302 is provided on the L-shaped plate 301. The T-shaped column 4 is slidably fitted into the through hole 302. A circular plate 303 is welded onto the T-shaped column 4. One end of the spring 304 is welded to the circular plate 303, and the other end of the spring 304 is welded to the outer wall of the vibrating screen 1. The pressing plate 305 is bolted to the T-shaped column 4.

[0028] When it is necessary to install the screen 2 onto the vibrating screen 1, firstly, pull out the pressing plate 305 so that one end of the T-shaped column 4 is positioned in the first limiting hole 102. Place the screen 2 between the connecting grooves 101 on both sides of the vibrating screen 1, aligning the second limiting hole 201 of the screen 2 with the first limiting hole 102 of the connecting groove 101. Then, push the pressing plate 305 inward so that one end of the T-shaped column 4 passes through the first limiting hole 102 and the second limiting hole 201 in sequence. As the screen moves inward, the circular plate 303 moves inward as well. The circular plate 303 presses against the spring 304. Then, after rotating the T-shaped column 4 by 90°, the pressing plate 305 is released. The spring 304 rebounds, causing the T-shaped column 4 to contact the screen 2, thus completing the installation of the screen 2. When it is necessary to remove the screen 2, first press the pressing plate 305 to release the contact with the screen 2, then rotate the T-shaped column 4 by 90°, and then pull the pressing plate 305 outward so that the T-shaped column 4 exits from the second limiting hole 201. The screen 2 can then be removed from the vibrating screen 1.

[0029] When screening polyethylene filler masterbatch is required, a feed hopper 6 is installed on the vibrating screen 1 by welding. The feed hopper 6 has a funnel-shaped opening. A first discharge frame 7 and a second discharge frame 8 are also installed on the vibrating screen 1 by welding. The first discharge frame 7 is located directly below the screen 2, and the second discharge frame 8 is located at the opening of the screen 2. The polyethylene filler masterbatch to be screened is poured into the vibrating screen 1 through the feed hopper 6. The vibration motor on the vibrating screen 1 is started by the control system. The screen 2 screens the material under the action of the vibration motor. Qualified small particles fall through the screen 2 into the first discharge frame 7, while larger particles remain on the screen 2 and move towards the opening of the screen 2 with vibration, eventually falling into the second discharge frame 8, thus completing the screening of polyethylene filler masterbatch.

[0030] The cleaning component 5 is mounted on the vibrating screen 1 and cooperates with the screen 2. The cleaning component 5 includes a cleaning brush 501, a rack plate 504, and a cross plate 505. The cleaning brush 501 contacts the surface of the screen 2. The bristles of the cleaning brush 501 are made of nylon, which has good wear resistance and flexibility, effectively cleaning the screen 2 without damaging the screen surface. Both ends of the cleaning brush 501 are bolted to a cylinder 502. Gears 503 are mounted on the cylinder 502 via key connections. Two rack plates 504 are provided and are bolted to the connecting groove 1. On 01, gear 503 meshes with rack plate 504. A rectangular hole 103 is provided on one of the connecting grooves 101. A cylinder 502 is slidably engaged with the rectangular hole 103. The end of one cylinder 502 away from the cleaning brush 501 is installed with the power output shaft of the drive source through a coupling. The drive source can be a Y112M-4 model three-phase asynchronous motor. The horizontal plate 505 is installed on the vibrating screen 1 by welding. A sliding groove 506 is provided on the horizontal plate 505. A motor support plate is bolted to the bottom of the three-phase asynchronous motor. The motor support plate is slidably engaged with the sliding groove 506.

[0031] When cleaning of screen 2 is required, vibrating screen 1 stops working and drives the power output shaft of the three-phase asynchronous motor to rotate via an external controller. The power output shaft of the three-phase asynchronous motor drives the two cylinders 502 and the cleaning brush 501 to rotate via a coupling. The cylinders 502 drive the gear 503 to move on the rack plate 504. While one of the cylinders 502 moves on the rectangular hole 103, it drives the three-phase asynchronous motor to slide on the slide groove 506, so that the cleaning brush 501 can reciprocate along the connecting groove 101 to clean screen 2, avoid screen 2 from clogging, ensure that screen 2 always maintains good screening performance, and extend the service life of screen 2.

[0032] The preferred embodiments of this utility model disclosed above are merely illustrative of the present utility model. These preferred embodiments do not exhaustively describe all details, nor do they limit the utility model to the specific implementations described. Clearly, many modifications and variations can be made based on the content of this specification. This specification selects and specifically describes these embodiments to better explain the principles and practical applications of this utility model, thereby enabling those skilled in the art to better understand and utilize it. This utility model is limited only by the claims and their full scope and equivalents.
