Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] Specific examples are given below.

[0025] See also Figure 1-Figure 5 The utility model provides a functional plastic masterbatch screening device, comprising a vibrating plate 1, a collecting box 11 is fixedly connected to the top of the vibrating plate 1; a plurality of vibrating screens 12 are installed above the collecting box 11; a top cover 13 is fixedly connected to the top of the top vibrating screen 12; a feed hopper 14 is fixedly connected to the middle of the upper surface of the top cover 13; a discharge port 15 is fixedly connected to the bottom of the collecting box 11; a symmetrically arranged mounting assembly is arranged between every two vibrating screens 12, and the mounting assembly comprises a mounting block 2, a U-shaped plate 21 and an insertion rod 23; the insertion rod 23 is inserted into the mounting block 2 and the U-shaped plate 21; a mounting assembly is arranged between the bottom vibrating screen 12 and the collecting box 11; a sieve hole 16 is opened at the bottom of each vibrating screen 12.

[0026] During operation, in the current prior art, although the high-speed rotation of the screen cover can improve the efficiency of plastic masterbatch screening and prevent blockage from occurring above, when one or more of the vibrating screens 12 need to be replaced, if the vibrating screen 12 disc to be replaced is located below, the upper vibrating screen 12 disc needs to be removed together, which adds additional operating steps and reduces work efficiency; when it is necessary to replace one or more vibrating screens 12, the mounting block 2 is moved out by the insertion rod 23, and the mounting block 2 loses its fixation at this time, so that the vibrating screen 12 can be replaced. When the vibrating screen 12 is installed, the mounting block 2 is inserted into the U-shaped plate 21, and the insertion rod 23 is inserted into the mounting block 2, so that the vibrating screen 12 can be fixed, and the vibrating screen 12 that needs to be removed can be directly removed and replaced, which reduces the operating steps and does not reduce work efficiency.

[0027] Further, such as Figure 2 , Figure 4 and Figure 5As shown, the mounting block 2 is fixedly connected to the lower outer side of the vibrating screen 12; the U-shaped plate 21 is fixedly connected to the collecting box 11 and the position of the mounting block 2 above the vibrating screen 12, and the mounting block 2 is inserted in the middle of the U-shaped plate 21; the mounting assembly also includes an L-shaped plate 22, and the L-shaped plate 22 is fixedly connected to the side of the U-shaped plate 21 away from the vibrating screen 12; the insertion rod 23 is slidably connected to the middle of the L-shaped plate 22; the mounting block 2 and the U-shaped plate 21 are provided with a slot 27 at the position corresponding to the insertion rod 23, and the insertion rod 23 is inserted into the slot 27; a positioning ring 24 is fixedly connected to the outer side of the insertion rod 23, and the positioning ring 24 is in contact with the outer side of the U-shaped plate 21; a spring 25 is fixedly connected to the side of the positioning ring 24 away from the U-shaped plate 21, and the other end of the spring 25 is fixedly connected to the L-shaped plate 22; the spring 25 is located on the outer side of the insertion rod 23; a pull ring 26 is fixedly connected to the end of the insertion rod 23 away from the U-shaped plate 21.

[0028] During operation, when it is necessary to replace one or more of the vibrating screens 12, the staff pulls the pull ring 26, and the pull ring 26 drives the insertion rod 23 to move, so that the insertion rod 23 is moved out of the mounting block 2. At this time, the mounting block 2 loses its fixation, so that the vibrating screen 12 can be replaced. When installing the vibrating screen 12, the mounting block 2 is inserted into the U-shaped plate 21. Because when the pull ring 26 is pulled, the positioning ring 24 will move together, and the movement of the positioning ring 24 will squeeze the spring 25. The spring 25 will shrink under the squeezing and will give a thrust to the positioning ring 24 and the insertion rod 23. Therefore, after the mounting block 2 is inserted into the U-shaped plate 21, the pull ring 26 is slowly released. Under the action of the thrust of the spring 25, the insertion rod 23 is inserted into the slot 27, so that the vibrating screen 12 can be fixed, and the vibrating screen 12 that needs to be removed can be directly removed and replaced, which reduces the operation steps and does not reduce work efficiency.

[0029] Further, such as Figure 2 As shown, the U-shaped plate 21 is rotatably connected to the first rotating rod 3 corresponding to the position of the positioning ring 24 ; the first rotating rod 3 is fixedly connected to the end away from the U-shaped plate 21 with a clamping rod 31 .

[0030] During operation, after pulling the pull ring 26 to move the positioning ring 24, rotate the No. 1 rotating rod 3 to make the clamping rod 31 close to the insertion rod 23 and the positioning ring 24, and make the clamping rod 31 clamped on the outside of the insertion rod 23, and at the same time fit with the side of the positioning ring 24 away from the spring 25, so that the positioning ring 24 and the insertion rod 23 can be fixed, making it convenient to take the vibrating screen 12.

[0031] Further, such as Figure 4 and Figure 5 As shown, the end of the insertion rod 23 away from the pull ring 26 is provided with a first arc surface 28; the position of the mounting block 2 corresponding to the slot 27 is provided with a second arc surface 29, and the first arc surface 28 and the second arc surface 29 are used in conjunction with each other.

[0032] During operation, through the No. 1 arc surface 28 opened on the insertion rod 23 and the No. 2 arc surface 29 opened on the mounting block 2, when the insertion rod 23 is inserted into the slot 27, the No. 1 arc surface 28 will first contact the No. 2 arc surface 29, thereby facilitating the insertion of the insertion rod 23 into the slot 27.

[0033] Further, such as Figure 3 As shown, a second rotating rod 4 is rotatably connected inside the feed hopper 14 ; a plurality of evenly arranged blades 41 are fixedly connected to the outer side of the second rotating rod 4 .

[0034] During operation, through the No. 2 rotating rod 4 fixed inside the feed hopper 14 and the blade 41 fixed outside the No. 2 rotating rod 4, after the plastic masterbatch is added into the feed hopper 14, the blade 41 will restrict the plastic masterbatch, so that the plastic masterbatch is slowly added into the vibrating screen 12, thereby preventing the plastic masterbatch from accumulating in the uppermost vibrating screen 12.

[0035] Further, such as Figure 3 As shown, the apertures of the plurality of groups of sieve holes 16 decrease sequentially from top to bottom.

[0036] Working principle:

[0037] When it is necessary to replace one or more of the vibrating screens 12, the staff pulls the pull ring 26, and the pull ring 26 drives the insertion rod 23 to move, so that the insertion rod 23 is moved out of the mounting block 2. At this time, the mounting block 2 loses its fixation, so that the vibrating screen 12 can be replaced. When installing the vibrating screen 12, the mounting block 2 is inserted into the U-shaped plate 21. Because when the pull ring 26 is pulled, the positioning ring 24 will move together, and the movement of the positioning ring 24 will squeeze the spring 25. The spring 25 will shrink under the squeezing and will give a thrust to the positioning ring 24 and the insertion rod 23. Therefore, after the mounting block 2 is inserted into the U-shaped plate 21, the pull ring 26 is slowly released. Under the action of the thrust of the spring 25, the insertion rod 23 is inserted into the slot 27, so that the vibrating screen 12 can be fixed, and the vibrating screen 12 that needs to be removed can be directly removed and replaced, which reduces the operation steps and does not reduce work efficiency.

[0038] The above shows and describes the basic principle, main features and advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments, and the above embodiments and descriptions are only for explaining the principle of the utility model. Without departing from the spirit and scope of the utility model, the utility model may have various changes and improvements, and these changes and improvements fall within the scope of the utility model to be protected.
