Description

Technical Field

[0001] This utility model belongs to the technical field of plastic particle screening devices, and particularly relates to a particle size screening device for rotational molding special materials. Background Technology

[0002] A patent entitled "A Particle Screening Machine" is disclosed in the existing Chinese patent database, with application number CN202420187821.X and application date of 2024-01-25. This particle screening machine includes a housing with a feed box connected to its top. Three sets of screening plates are arranged in the inner cavity of the housing. Three sets of mounting cavities are formed on the left side wall of the inner cavity, each containing a vertically mounted slide rod. The left side of each screening plate is slidably connected to the slide rod via a slider fitted onto it. The right side of each screening plate is fixedly connected to the right side of the inner cavity of the housing. Springs are provided on both the upper and lower sides of the connection between the slide rod and the slider. This invention utilizes mounting cavities within the housing, with slide rods and springs installed within them. The slide rods, in conjunction with the springs, vibrate the screening plates, causing the particles falling onto the screening plates to disperse due to the spring vibration. This results in a more complete screening process and more accurate particle grading.

[0003] When existing rotational molding materials are put into use, it is necessary to ensure that the particle size meets the process requirements. Therefore, this paper aims to propose a particle size screening device for rotational molding materials, which can quickly and efficiently screen rotational molding particles for subsequent selection and use.

[0004] The technical problem to be solved by this utility model is how to provide a device that can quickly and efficiently screen rotational molding particles. In order to improve its shortcomings, this utility model provides a particle size screening device for rotational molding special materials.

[0005] To achieve the above objectives, this utility model is implemented through the following technical solution:

[0006] A particle size screening device for rotational molding special materials includes a base, a power component on the upper surface of the base, a rotating shaft connected to the output end of the power component, a connecting body integrally formed into an inclined column at the upper end of the rotating shaft, a convex shaft at the edge of the upper surface of the connecting body, a vertical rod connected to the convex shaft via a bearing, a screening component integrally formed at the upper end of the vertical rod, an extension section integrally formed on the side of the vertical rod, a swing rod connected to the extension section via a universal ball joint, a U-shaped plate integrally formed at the free end of the swing rod, a vertical guide column on the base, an arc-shaped groove at the upper end of the guide column, and a pin inserted between the two ear plates of the U-shaped plate, the pin being located within the groove.

[0007] As a preferred embodiment, the screening component includes a screening box, a screen is provided in the middle of the screening box, and a discharge port is provided on the bottom side of the screening box.

[0008] As a preferred embodiment, a number of mounting blocks are integrally provided on the inner wall of the screening box, and a number of countersunk holes are provided at the edge of the screen. The screen is connected to each mounting block by countersunk bolts and fixed inside the screening box.

[0009] As a preferred embodiment, the bottom of the vertical rod is provided with a blind hole that connects to the convex shaft.

[0010] As a preferred embodiment, the power component includes a drive motor.

[0011] Compared with the prior art, the beneficial effects of this utility model are: due to the coordinated arrangement of the screening components, connecting body and swing rod, the rotational molding particles are filtered through the screen during the swinging process of the screening box and discharged through the discharge port, thereby screening out rotational molding particles of the required size that meet the process requirements, improving the processing effect. This device is suitable for industrial production and has strong practicality. Attached Figure Description

[0016] The technical solution of this application will be further described below with reference to the accompanying drawings and embodiments.

[0017] like Figure 1-3 As shown, this is a particle size screening device for rotational molding materials. It includes a base 1, a power component 2 on the upper surface of the base 1, a rotating shaft 3 connected to the output end of the power component 2, a connecting body 4 integrally formed into an inclined column shape at the upper end of the rotating shaft 3, a convex shaft 5 on the upper edge of the connecting body 4, a vertical rod 6 connected to the convex shaft 5 via a bearing, a screening component 7 integrally formed at the upper end of the vertical rod 6, an extension section 8 integrally formed on the side of the vertical rod 6, a swing rod 9 integrally formed on the extension section 8 via a universal ball joint, a U-shaped plate 10 integrally formed at the free end of the swing rod 9, a vertical guide column 11 on the base 1, an arc-shaped groove 12 at the upper end of the guide column 11, and a pin 13 inserted between the two ear plates of the U-shaped plate 10, the pin 13 being located within the groove 12. The screening component 7 includes a screening box 701, a screen 702 in the center of the screening box 701, and a discharge port 703 on the bottom side of the screening box 701. Several mounting blocks 14 are integrally formed on the inner wall of the screening box 701. Several countersunk holes are opened at the edge of the screen 702. The screen 702 is connected to each mounting block 14 by countersunk bolts and fixed inside the screening box 701. A blind hole is opened at the bottom of the vertical rod 6 to connect with the convex shaft 5. The power unit 2 includes a drive motor.

[0018] During operation, the operator controls the rotation of the shaft 3 by opening and closing the power component 2. The connecting body 4 rotates together with the shaft 3. At the same time, the convex shaft 5 on the connecting body 4 drives the bottom of the vertical rod 6 to rotate. The rotation trajectory is set to draw a circle with the uppermost horizontal plane of the connecting body 4. Since the side extension section 8 of the vertical rod 6 is connected to the swing rod 9 through a universal ball joint, and the U-shaped plate 10 is slidably engaged in the slide groove 12 through the pin 13, the swing trajectory of the U-shaped plate 10 is set along the slide groove 12, swinging up and down. At the same time, the vertical rod 6 can form an X-shaped three-dimensional structure during the swing. The screening component 7 can screen the rotomolded particles on the screen 702 during the swing with the vertical rod 6. At the same time, when the screening box 701 is in an inclined state, the rotomolded particles can be discharged through the discharge port 703 due to their own gravity, achieving simultaneous screening and discharge, and avoiding the accumulation of particles in the space below the screen 702, which would prevent continuous screening.

[0019] This utility model is not limited to the above embodiments. Based on the technical solutions disclosed in this utility model, those skilled in the art can make some substitutions and modifications to some of the technical features without creative labor, and these substitutions and modifications are all within the protection scope of this utility model.
