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 novel colorant used in polymer materials, also known as pigment preparation. Primarily used in plastics, color masterbatch consists of pigments or dyes, carriers, and additives. It is an aggregate made by uniformly attaching a supermassive amount of pigment to resin. It can be called a pigment concentrate, so its tinting strength is higher than that of the pigment itself. Therefore, during the production of color masterbatch, a screening device is needed to assist in separating it into different particle sizes.

[0003] In the prior art, patent document CN218797185U discloses a screening device for masterbatch production. This device includes a screening box with a filter screen mechanism inside and a vibration mechanism on the outside. Three vibration grooves are equidistantly spaced on both sides of the inner wall of the screening box. A convenient disassembly mechanism is installed inside each vibration groove, and vibration springs are fixedly connected to the bottom of each of the six vibration grooves. The convenient disassembly mechanism includes a hollow slider, with a hollow slider fixedly connected to the top of each of the six vibration springs. The outer side of the hollow slider is slidably connected to the vibration groove. The beneficial effect of this invention is that it solves the problem of traditional devices being unable to flexibly replace the filter screen during practical application. After screening one type of masterbatch, the color of that masterbatch will stick to the filter screen, causing the screened masterbatch color to be mixed in when processing other colors of masterbatch, affecting the quality and purity of the masterbatch. This invention greatly improves the compatibility of the device compared to traditional devices.

[0004] To address the issue of the inability to flexibly replace the filter screen, existing technology involves movably connecting the filter screen to a hollow slider, allowing the filter screen to vibrate with the hollow slider and be easily disassembled. However, this method still results in the screening unit being a closed space during use, leading to a reduction in screening efficiency. Utility Model Content

[0026] The present invention will be further described in detail below with reference to embodiments: Example

[0027] like Figure 1-5 As shown, this utility model provides a screening device for masterbatch production, including a support base 1; a collection box 2 disposed on the upper surface of the support base 1 for collection; a secondary screening unit 3 fixedly connected to the upper surface of the support base 1, and a primary screening unit 4 disposed on the upper surface of the support base 1 for screening. The secondary screening unit 3 includes an adjustment component disposed on the upper surface of the support base 1 and a secondary screening component disposed on the outer surface of the adjustment component. The primary screening unit 4 includes a lifting component disposed on the upper surface of the support base 1 and a primary screening component disposed on the outer surface of the lifting component. The adjustment component includes a limiting guide rail 31, the bottom surface of which is fixedly connected to the upper surface of the support base 1. A limiting slide rod 33 is detachably connected to the inner wall of the limiting guide rail 31, and a fixing bolt 32 is detachably connected to the inner wall of the limiting guide rail 31. The secondary screening component includes a secondary screening box 34, the bottom end of which is slidably connected to the inner wall of the limiting guide rail 31, and the inner wall of the bottom end of the secondary screening box 34 is slidably connected to the outer surface of the limiting slide rod 33. A fixing plate 37 is fixedly connected to the inner wall of the secondary screening box 34. A discharge box 310 is fixedly connected to one side of the secondary screening box 34. An elastic column 38 is detachably connected to the upper surface of the fixing plate 37. A secondary screening screen plate 35 is fixedly connected to the upper surface of the elastic column 38. A leak-proof baffle 39, which is detachably connected to the inner wall of the secondary screening box 34, is detachably connected to the outer surface of the secondary screening screen plate 35. A vibrator 36 is detachably connected to the bottom surface of the secondary screening screen plate 35. (The last sentence appears to be incomplete and possibly refers to a process involving color masterbatch.) If secondary screening is required during screening, the secondary screening box 34 can be moved under the limit of the limiting slide bar 33 by rotating the fixing bolt 32, so that it moves directly below the primary screening box 44, and then the masterbatch is screened. During the screening process, the secondary screening screen plate 35 can be driven to vibrate under the limit of the elastic column 38 by starting the vibrator 36, thereby screening the masterbatch. The screened masterbatch is discharged from the bottom of the secondary screening box 34, while the unscreened masterbatch is discharged from the discharge box 310. Example

[0028] like Figure 1-5As shown, based on Embodiment 1, this utility model provides a technical solution: Preferably, the lifting assembly includes a sleeve 41, the bottom surface of the sleeve 41 is fixedly connected to the upper surface of the support base 1, the inner wall of the sleeve 41 is slidably connected to a lifting frame 42, and the outer surface of the sleeve 41 is detachably connected to a hydraulic cylinder 43.

When it is necessary to screen the masterbatch, firstly, the hydraulic cylinder 43 is started to drive the primary screening box 44 to rise and fall under the limit of the lifting frame 42 and the sleeve 41, thereby adjusting the height of the primary screening box 44, so as to facilitate the input of the masterbatch into the primary screening box 44, and then the primary screening screen plate 45 is used to assist in the screening of the masterbatch.

[0029] The working principle of the screening device used in the production of masterbatch will be explained in detail below.

Then, the primary screening screen plate (45) is used to assist in screening the masterbatch. If secondary screening is required, the secondary screening box (34) can be moved under the limit of the limit slide bar (33) by rotating the fixing bolt (32), so that it moves to the bottom of the primary screening box (44) and then the masterbatch is screened. During the screening process, the vibrator (36) can be started to drive the secondary screening screen plate (35) to vibrate under the limit of the elastic column (38), thereby screening the masterbatch. The screened masterbatch is discharged from the bottom of the secondary screening box (34), while the unscreened masterbatch is discharged from the discharge box (310).

[0031] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the protection scope of the present invention.
