Description

Technical Field

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

[0002] Matte masterbatch is a functional plastic additive mainly used to reduce the surface gloss of plastic products and achieve a matte or frosted effect. In the production process of matte masterbatch, the masterbatch needs to be screened to facilitate subsequent processing.

[0003] In the prior art, patent document CN222571322U discloses a screening device for color masterbatch processing, including a box body. Multiple sieve plates are movably arranged inside the box body, and a vibrating motor is fixedly installed at the bottom center of each sieve plate. A barrel with an open top is fixedly installed at the top of the box body. A centrifugal dewatering cylinder is rotatably mounted on the bottom surface of the barrel body, and a motor driving the centrifugal dewatering cylinder is fixedly installed at the top of the barrel body. The bottom outlet of the centrifugal dewatering cylinder extends into the box body. A feed inlet is located at the top of the centrifugal dewatering cylinder, and a drain outlet is located at the bottom side of the barrel body. By employing a centrifugal dewatering cylinder and a hot air drying system, color masterbatch can be dehydrated and dried immediately after extrusion, greatly shortening the preparation time before screening and improving screening efficiency. Through centrifugal dewatering and hot air drying, moisture in the color masterbatch is effectively removed, avoiding caking problems caused by excessive water content, ensuring the quality stability and consistency of the color masterbatch, and thus improving the quality of the final plastic products.

[0004] To address the issue of caking in color masterbatches with high moisture content during screening, existing technologies employ centrifugal dehydration drums and hot air drying systems to dehydrate and dry the masterbatches immediately after extrusion. However, this method is inconvenient for feeding materials during use, which reduces the practicality of the screening device. Utility Model Content

Detailed Implementation

[0027] The present invention will be further described in detail below with reference to embodiments: Example

[0028] like Figure 1-5As shown, this utility model provides a screening device for processing matte masterbatch, including a support frame 1; a screening unit 2 disposed inside the support frame 1 for screening; and a feeding unit 3 disposed on the top of the support frame 1 for feeding material. The screening unit 2 includes a transmission component disposed inside the support frame 1 and a screening component disposed inside the transmission component. The feeding unit 3 includes a feeding component disposed on the top of the support frame 1 and an agitation component disposed on the outer surface of the feeding component. The transmission component includes a screening box 21, the outer surface of which is fixedly connected to the inner wall of the support frame 1. Both ends of the screening box 21 are provided with discharge troughs, and both ends of the screening box 21 are detachably connected to discharge trough bodies 26. A drive motor 22 is detachably connected to the outer surface of the screening box 21, and the drive end of the drive motor 22 is rotatably connected to a transmission belt 23 rotatably connected to the inner wall of the screening box 21. The screening component includes a screening screen 24, the outer surface of which is flush with the screen. The inner wall of the screening box 21 is detachably connected. Below the screening screen 24, there is a guide plate 25 that is fixedly connected to the inner wall of the screening box 21. The guide plate 25 is inclined inside the screening box 21. There are two sets of screening screen 24 and guide plate 25, and the specifications of the screening screen 24 are different. When using the screening device for matte masterbatch processing, the masterbatch to be screened is first put into the feeding unit 3 for feeding. After the matte masterbatch enters the interior of the screening box 21, the drive motor 22 can be started to drive multiple conveyor belts 23 inside the screening box 21 for transmission. When the matte masterbatch is transmitted to one side and falls onto the outer surface of the screening screen 24, it can be screened. The screened masterbatch will fall onto the guide plate 25 for discharge, while the unscreened masterbatch will fall onto the next conveyor belt 23 for transmission. Similarly, screening is carried out again using screening screens 24 of different specifications. Finally, the remaining masterbatch is discharged from one side of the screening box 21. Example

[0029] like Figure 1-5As shown, based on Embodiment 1, this utility model provides a technical solution: Preferably, the feeding assembly includes a feeding box 31, the bottom surface of the feeding box 31 is fixedly connected to the upper surface of the support frame 1, and a distribution plate 32 is fixedly connected to the inner wall of the feeding box 31. The stirring assembly includes a pneumatic cylinder 33, one side of the pneumatic cylinder 33 is detachably connected to the outer surface of the feeding box 31, and a fixing plate 35 is detachably connected to the telescopic end of the pneumatic cylinder 33. A limiting slide rod 34, which is detachably connected to the inner wall of the feeding box 31, is slidably connected to the inner wall of the fixing plate 35. A slidable baffle plate 36, which is slidably connected to the outer surface of the distribution plate 32, is fixedly connected to the outer surface of the fixing plate 35. A mounting frame 38 is fixedly connected to the outer surface of the mounting frame 38. The feed box 31 is fixedly connected to the inner wall of the feeding box 31. First, the matte masterbatch to be screened is put into the feeding box 31, so that it is dispersed into the screening box 21 by the diversion action of the distribution plate 32. During the diversion process of the distribution plate 32, the pneumatic cylinder 33 is activated to drive the fixed plate 35 to move under the limit of the limiting slide rod 34, thereby driving the agitator plate 36 to move in the horizontal direction to agitate the masterbatch, prevent the masterbatch from being blocked before entering the screening box 21, and break up the clumps of masterbatch. During the movement, the fixed plate 35 is limited by the mounting frame 38 and the limiting spring column 37, which can cooperate with the pneumatic cylinder 33 to make the agitator plate 36 move back and forth continuously, thereby increasing the agitation effect on the matte masterbatch.

[0030] The working principle of the screening device for matte masterbatch processing will be explained in detail below.

[0031] like Figure 1-5As shown, the matte masterbatch to be screened is first placed in the feeding box 31, so that it is dispersed into the screening box 21 by the diversion action of the distribution plate 32. During the diversion process of the distribution plate 32, the pneumatic cylinder 33 is activated to drive the fixed plate 35 to move under the limit of the limiting slide rod 34, thereby driving the agitator plate 36 to move in the horizontal direction to agitate the masterbatch, prevent the masterbatch from clogging before entering the screening box 21, and break up the clumped masterbatch. During the movement, the fixed plate 35 is limited by the mounting bracket 38 and the limiting spring column 37, which can cooperate with the pneumatic cylinder 33 to make the agitator plate 36 move back and forth continuously. The movement of the screen increases the agitation effect on the matte masterbatch. When using the screening device for matte masterbatch processing, after the matte masterbatch enters the screening box 21, the drive motor 22 can be started to drive multiple conveyor belts 23 inside the screening box 21 for transmission. When the matte masterbatch is transmitted to one side and falls onto the outer surface of the screening screen plate 24, it can be screened. The screened masterbatch will fall onto the guide plate 25 for discharge, while the unscreened masterbatch will fall onto the next conveyor belt 23 for transmission. Similarly, screening can be performed again using screening screen plates 24 of different specifications. Finally, the remaining masterbatch can be discharged from one side of the screening box 21.

[0032] 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.
