Description

Technical Field

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

[0002] Color masterbatch is a plastic colorant made by dispersing a high proportion of pigments or additives with thermoplastic resin. The resin used has good wetting and dispersing properties for the colorant and good compatibility with the material being colored. During the production process, color masterbatch needs to be sieved according to its size, thus requiring the use of a sieving device.

[0003] Currently, masterbatches are prone to clumping during storage, and the degree of clumping varies greatly. Existing screening devices are not convenient for screening according to the severity of clumping. When screening clumped masterbatches, they are easily crushed or ground. There is an urgent need to design a screening device for masterbatch production to solve the above problems. Utility Model Content

[0008] Furthermore, a slot is provided at the top of the rotating cylinder, a hot air blower is provided at the top of the rotating cylinder, and an air outlet corresponding to the slot is provided at the bottom of the hot air blower.

[0009] Furthermore, the adjustment mechanism includes a channel formed at one end of the rotating cylinder, a slider that slides within the channel, and a lead screw that rotates within the channel.

[0021] like Figure 1-4 As shown in the figure, this utility model provides a screening device for the production of color masterbatch.

[0022] The system includes a support frame 1, a rotating cylinder 2 rotatably fitted inside the support frame 1, a screening cylinder 3 rotatably fitted inside the rotating cylinder 2, a fixed rod 4 installed inside the screening cylinder 3, a rotating shaft 5 located in the middle of the fixed rod 4, a first motor 6 installed at one end of the rotating cylinder 2, the output end of the first motor 6 connected to one end of the rotating shaft 5, and a baffle 7 rotatably fitted at the other end of the rotating cylinder 2; two fixed frames 8 are provided at the bottom of the rotating cylinder 2, the fixed frames 8 are connected to the rotating cylinder 2, a collection box 9 is slidably fitted inside the fixed frames 8, a shaking mechanism 10 is provided inside the support frame 1 that cooperates with the rotating cylinder 2, a sliding groove 11 is provided at both ends of the fixed rod 4, a plastic roller 12 is elastically fitted and rotatably fitted inside the sliding groove 11, an arc-shaped seat 13 is slidably fitted inside the rotating cylinder 2, a friction wheel 14 is provided at one end of the plastic roller 12, frictional resistance is provided between the arc-shaped seat 13 and the friction wheel 14, and an adjustment mechanism 15 is provided between the rotating cylinder 2 and the arc-shaped seat 13.

[0023] The slide groove 11 is equipped with a spring plate with an arc-shaped bottom end. The bottom end of the spring plate abuts against the circumference of the middle part of the plastic roller 12, so that the plastic roller 12 can rotate while sliding elastically in the slide groove 11.

[0024] Reference Figure 2 The shaking mechanism 10 in this embodiment includes a second motor 16 mounted on one side of the support 1, a rotating rod 17 rotatably fitted inside the support 1, two rotating plates 18 respectively mounted on both sides of the rotating rod 17, and two connecting rods 19 respectively rotatably connected to one end of the two rotating plates 18. One end of the two connecting rods 19 is rotatably connected to the bottom of both ends of the rotating cylinder 2. The output end of the second motor 16 is connected to one end of the rotating rod 17. Two pads 20 are provided at the bottom of the inner wall of the support 1, and the two pads 20 correspond to one end of the two rotating plates 18 respectively. By starting the second motor 16, the rotating rod 17 will be driven to rotate, causing the rotating rod 17 to drive the two rotating plates 18. The two rotating plates 18 will rise and fall, causing the two rotating plates 18 to drive the two connecting rods 19 respectively. The two connecting rods 19 will drive the two ends of the rotating cylinder 2 respectively, causing the rotating cylinder 2 to rotate and tilt. The rotating rod 17 rotates back and forth, causing the rotating cylinder 2 to shake and screen.

[0025] Reference Figure 2 In this embodiment, the top of the rotating cylinder 2 is provided with a slot 21, and a hot air blower 22 is provided at the top of the rotating cylinder 2. The bottom of the hot air blower 22 is provided with an air outlet 23 corresponding to the slot 21. Through the hot air blower 22, hot air can be blown into the rotating cylinder 2 through the slot 21, so that a dry environment is formed inside the rotating cylinder 2, which is beneficial to the dispersion of the masterbatch.

[0026] Reference Figure 3 The adjustment mechanism 15 in this embodiment includes a channel 24 formed at one end of the rotating cylinder 2, a slider 25 slidably fitted within the channel 24, and a lead screw 26 rotatably fitted within the channel 24. A rotating wheel is installed at the bottom end of the lead screw 26. The lead screw 26 and the slider 25 are threadedly fitted, and one side of the slider 25 is fixedly connected to one side of the arc-shaped seat 13. By rotating the lead screw 26, the slider 25 is moved, which in turn moves the arc-shaped seat 13, adjusting its position. The slider 25 always blocks the channel 24 to prevent the masterbatch from leaking out of the channel 24.

[0027] Reference Figure 4 In this embodiment, a fixing plate 27 is installed at one end of the rotating cylinder 2. The fixing plate 27 is semi-circular, and a feed hopper 28 is provided on one side of the fixing plate 27. Through the feed hopper 28, color masterbatch can be added into the feed hopper 28, so that the color masterbatch enters the screening cylinder 3 inside the rotating cylinder 2 through the feed hopper 28.

[0028] Reference Figure 4 In this embodiment, the baffle 7 is rotatably fitted to the bottom of the fixed plate 27. A retaining plate 29 is rotatably fitted to one side of the baffle 7. One end of the retaining plate 29 has a retaining groove 30, and a retaining rod 31 is installed at one end of the rotating cylinder 2. The retaining groove 30 and the retaining rod 31 are engaged. By using the retaining plate 29, when the baffle 7 rotates to fit against one end of the rotating cylinder 2, the retaining plate 29 can be rotated to engage the retaining groove 30 with the retaining rod 31, thereby fixing the baffle 7.

[0029] Working principle: In use, first pour the masterbatch to be screened into the screening cylinder 3, rotate the closed baffle 7 to start the first motor 6 and the shaking mechanism 10. The first motor 6 will drive the rotating shaft 5 to rotate, so that the rotating shaft 5 drives the screening cylinder 3 to rotate through the fixed rod 4, so that the screening cylinder 3 screens the masterbatch. At the same time, the shaking mechanism 10 will drive the rotating cylinder 2 to shake back and forth, so that the rotating cylinder 2 drives the screening cylinder 3 to shake and screen. The masterbatch that passes through the screening cylinder 3 will enter the collection box 9 through the fixed frame 8. When processing agglomerated masterbatch, the adjustment mechanism 15 is adjusted as needed to adjust the height of the arc-shaped seat 13. While the fixed rod 4 drives the screening cylinder 3 to rotate, the fixed rod 4 will drive the plastic roller 12 to move in a circle, so that the friction wheel 14 of the plastic roller 12 is in contact with the arc-shaped seat 13 and rubs against it. This allows the plastic roller 12 to stir and press the agglomerated masterbatch, causing it to disperse. The pressing height of the plastic roller 12 can be adjusted by adjusting the height of the arc-shaped seat 13 according to the size and degree of agglomerated masterbatch.

[0030] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
