Description

Technical Field

[0001] The utility model relates to a screening device, in particular to a screening device for resin blanks. Background Art

[0002] Resin stock refers to the basic material used to manufacture a variety of products. Due to its excellent processing properties, diverse performance characteristics, and wide range of applications, it plays a vital role in multiple industries. By selecting the appropriate resin type and adding various fillers, plasticizers, curing agents, pigments, and other additives, resin stock can be prepared to meet specific performance requirements for the manufacture of various parts or products. Screening is a crucial step in the resin stock production process, ensuring that the fillers and other components in the resin stock have a uniform particle size.

[0003] Although existing screening devices can complete basic screening tasks, they have some obvious shortcomings in terms of function and performance. For example, most screening devices directly add fillers for screening, resulting in the inability to accurately control the amount of filler fed, which can easily cause too much or too little filler to enter the screening cylinder, and may cause uneven distribution during the screening process, affecting the screening efficiency. In addition, during the screening process, the filler has poor fluidity on the screen and may accumulate on the screen, especially in the center of the screen, which can easily affect the screening effect.

[0004] Therefore, a screening device for resin blanks is particularly needed to solve the above problems. Utility Model Content

A drive motor is installed on the front side of the top of the working cylinder. A gear is fixedly connected to the output shaft of the drive motor. The gear and the ring gear have equal thickness and are engaged.

[0008] Furthermore, the bulk material mechanism includes a spiral ring, a connecting rod and a fixed rod. The fixed rod is fixedly connected to the center position of the baffle, which passes through the two screens and is fixedly connected to the outside with multiple connecting rods distributed up and down. Every four connecting rods are on the same horizontal plane, and a spiral ring is fixedly connected between the ends close to the inner wall of the working cylinder, and the bottom surface of the spiral ring is in contact with the top surface of the screen.

[0009] Furthermore, it also includes a support ring and a spring. The support ring is fixedly connected to the base, and a plurality of springs distributed along the circumferential direction are connected between the support ring and the working cylinder.

[0010] Furthermore, a scraper is included. One end of the spiral ring close to the inner wall of the working cylinder is fixedly connected to the scraper, and the bottom surface of the scraper contacts the top surface of the edge of the screen.

[0012] From the above description of the structure of the present invention, it can be seen that the design starting point, concept and advantages of the present invention are:

[0013] The utility model sets a quantitative mechanism, starts the driving motor, and meshes the gear with the gear ring, so that the connecting block drives the baffle to rotate, and the second discharge hole is intermittently aligned with the two first discharge holes, and the filler in the silo is quantitatively discharged into the working cylinder, ensuring that the discharge amount is consistent each time, thereby improving the uniformity and efficiency of screening. In addition, by setting a bulk material mechanism, the fixed rod drives the spiral ring to rotate, guiding the filler to be evenly distributed on the screen along the spiral direction, thereby improving the fluidity of the filler, avoiding stagnation and accumulation of the filler on the screen, and improving the screening effect.

[0014] The utility model can limit the position of the screening drum by arranging the support ring and the spring, thereby ensuring that the screening drum will not separate from the base during the vibration process, thereby improving the overall stability of the device.

[0015] The utility model prevents the filler from piling up on the edge of the screen by arranging a scraper, thereby further improving the screening effect, and stirs the filler in the lower part of the silo by arranging a stirring rod, thereby avoiding the filler from piling up in the silo and ensuring that the filler can fall smoothly.

The inside of the working cylinder 5 is connected to a vibration motor 9 by bolts, and is connected to two screens 12 by welding. The vibration motor 9 is located below the two screens 12. A support ring 8 is connected to the base 7 by welding. A plurality of springs 10 distributed along the circumferential direction are connected between the support ring 8 and the working cylinder 5. It also includes a quantitative mechanism and a bulking mechanism. A quantitative mechanism is provided between the silo 1 and the working cylinder 5, and a bulking mechanism is provided on the quantitative mechanism.

[0023] See Figures 1-4As shown, the quantitative mechanism includes a baffle 102, a ring gear 3, a drive motor 4, a gear 401 and a connecting block 18. The upper part of the working cylinder 5 is rotatably connected to the connecting blocks 18 that are symmetrically distributed. The baffle 102 is connected to the bottom of the two connecting blocks 18 by welding. The bottom surface of the silo 1 is close to the top surface of the baffle 102. The baffle 102 is provided with a second discharge hole 17 that is the same size as the first discharge hole 101. The ring gear 3 is connected to the top of the two connecting blocks 18 by welding. The ring gear 3 is located outside the working cylinder 5. The front side of the top of the working cylinder 5 is connected to the drive motor 4 by bolts. The output shaft of the drive motor 4 is connected to the gear 401 by welding. The gear 401 is meshed with the ring gear 3 of equal thickness, and there is a gap between the bottom surfaces of the ring gear 3 and the gear 401 and the top surface of the working cylinder 5, which can prevent the ring gear 3 and the gear 401 from rubbing against the top surface of the working cylinder 5.

[0024] See Figure 2-Figure 3 As shown, the bulk material mechanism includes a spiral ring 11, a scraper 13, a connecting rod 14, a stirring rod 15 and a fixed rod 16. The center position of the baffle 102 is connected to the fixed rod 16 by welding. The fixed rod 16 passes through the two screens 12, and the outside is connected to a plurality of connecting rods 14 distributed up and down by welding. Every four connecting rods 14 are on the same horizontal plane, and the spiral ring 11 is connected between the ends close to the inner wall of the working cylinder 5 by welding. The bottom surface of the spiral ring 11 is in contact with the top surface of the screen 12. The end of the spiral ring 11 close to the inner wall of the working cylinder 5 is connected to the scraper 13 by welding, and the bottom surface of the scraper 13 is in contact with the top surface of the edge of the screen 12. The upper end of the fixed rod 16 penetrates into the interior of the silo 1 and is connected to a plurality of stirring rods 15 distributed in a circular path by welding. The stirring rod 15 is located above the baffle 102 and is inclined for guiding the flow of filler.

[0025] Initially, the second discharge hole 17 is staggered with the two first discharge holes 101, so that the silo 1 is in a closed state. First, the staff pours the filler to be screened into the silo 1, and then turns on the drive motor 4 and the vibration motor 9. The output shaft of the drive motor 4 drives the gear 401 to rotate, and the gear 401 is engaged with the ring gear 3, so that the ring gear 3 drives the connecting block 18 to rotate, and the connecting block 18 drives the baffle 102 to rotate, so that the second discharge hole 17 is intermittently aligned with the two first discharge holes 101, and the silo 1 is filled. The filler in the work cylinder 5 is quantitatively lowered into the work cylinder 5, and the lowered filler falls on the upper screen 12 in advance for the first screening. During screening, the large-particle filler stays on the upper screen 12, and the small-particle filler and fine impurities such as sand pass through the upper screen 12 and fall on the lower screen 12 for the second screening. During screening, the small-particle filler stays on the lower screen 12, and the fine impurities such as sand pass through the lower screen 12 and fall into the bottom of the work cylinder 5. In this process, the vibration motor 9 drives the work cylinder 5 to move. The working cylinder 5 vibrates to speed up the screening speed of the filler. When the working cylinder 5 vibrates, the extrusion spring 10 compresses or stretches the spring 10. During the screening process, the baffle 102 simultaneously drives the fixed rod 16 to rotate, and the fixed rod 16 drives the spiral ring 11 to rotate, guiding the filler to be evenly distributed on the screen 12 along the spiral direction to prevent the filler from stagnation on the screen 12. The fixed rod 16 simultaneously drives the stirring rod 15 to rotate, so that it stirs the filler at the lower part of the silo 1 to prevent the filler from accumulating in the silo 1. The spiral ring 11 simultaneously drives the scraper 13 to rotate, so that it scrapes the filler at the edge of the screen 12. After screening for a period of time, the large-particle filler accumulated on the upper screen 12 is discharged from the upper discharge port 6, and the small-particle filler accumulated on the lower screen 12 is discharged from the middle discharge port 6. The fine impurities such as sand accumulated at the bottom of the working cylinder 5 are discharged from the lower discharge port 6. After the screening is completed, ensure that the second discharge hole 17 is staggered with the two first discharge holes 101, and turn off the drive motor 4 and the vibration motor 9.
