Description

Technical Field

[0001] This utility model relates to the field of color masterbatch production technology, specifically to a color masterbatch screening system that prevents clogging. Background Technology

[0002] Color masterbatch is a granular colorant made by uniformly dispersing high-concentration pigments or dyes in a carrier resin and then processing them. In the color masterbatch production process, in order to ensure uniform particle size and remove impurities and foreign matter, a color masterbatch screening system is usually used to screen the color masterbatch after pelletizing.

[0003] In existing color masterbatch screening systems, color masterbatch is usually added into the screening machine through the feed port, and then the screen is driven to vibrate. Color masterbatch with the correct particle size passes through the screen and falls into the collection box under the vibration of the screen, while color masterbatch with an excessively large particle size flows out of the screening machine along the inclined screen.

[0004] The existing masterbatch screening system has the following problems: During the screening process, the masterbatch is screened by inertia and the vibration of the screen, which may cause the masterbatch to accumulate and block the screen, thus affecting the normal operation of the screening. Utility Model Content

[0005] The technical problem to be solved by this utility model is to overcome the existing defects and provide a color masterbatch screening system that prevents clogging. During the screening process of color masterbatch, the color masterbatch on the screen is scraped by the anti-clogging mechanism to avoid the situation where the color masterbatch accumulates together and clogs the screen, thus affecting the screening work. This can effectively solve the problems in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a clogging-resistant masterbatch screening system, comprising a screening machine and a microcontroller, wherein the microcontroller is fixedly connected to the front side of the screening machine, the input end of the microcontroller is electrically connected to an external power supply, and the screening machine is equipped with an adjustable screen.

[0007] It also includes an anti-blocking mechanism, which includes a sliding column, a rotating rod, a deflector plate, a contact plate, a rotating shaft, and a cam. The front side of the screening machine has evenly distributed sliding openings, and a sliding column is slidably connected inside each sliding opening. The outer surface of each sliding column is rotatably connected to an evenly distributed rotating rod. The lower end of the outer surface of each rotating rod is provided with a symmetrically distributed deflector plate. The front end of each sliding column is provided with a contact plate. A rotating shaft is rotatably connected to the front side of the screening machine. The outer surface of the rotating shaft is fixedly fitted with a cam corresponding to each contact plate. The outer surface of each cam is in contact with the front side of the adjacent contact plate.

[0008] Furthermore, the front side of the screening machine is equipped with a motor, the left end of the output shaft of the motor is fixedly connected to the right end of the rotating shaft, and the input end of the motor is electrically connected to the output end of the microcontroller to provide driving force.

[0009] Furthermore, the anti-blocking mechanism also includes springs. Springs are movably sleeved on the front end of the outer surface of the sliding column. The springs are located between the rear side of the adjacent contact plate and the front side of the screening machine, which facilitates the normal operation of the anti-blocking mechanism.

[0010] Furthermore, the anti-blocking mechanism also includes a guide assembly, which includes a limiting plate, a limiting groove, a gear, and a rack. The screening machine has a screening chamber inside, and the top wall of the screening chamber has a limiting groove corresponding to the sliding column. The upper end of the rotating rod is provided with a limiting plate, and the limiting plates are slidably connected to the inside of the adjacent limiting groove. The upper end of the outer surface of the rotating rod is fixedly fitted with a gear, and the top wall of the screening chamber is provided with a rack corresponding to the limiting groove. The gears are meshed with the adjacent racks to facilitate the rotation of the actuating plate.

[0011] Furthermore, the screening machine has sliding grooves on both the front and rear side walls, and each sliding groove has a limiting rod inside. A mounting frame is slidably connected between the two limiting rods. The mounting frame is inclined with the left side higher than the right side, and a screen is installed inside the mounting frame to facilitate the limiting of the screen.

[0012] Furthermore, a second cam is rotatably connected to the left side wall of the screening chamber via a rotating shaft. The outer surface of the second cam contacts the lower surface of the mounting frame. A second motor is provided on the left side of the screening chamber. The right end of the output shaft of the second motor is fixedly connected to the left end of the rotating shaft. The input end of the second motor is electrically connected to the output end of the microcontroller to facilitate screen vibration.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] During the screening process of masterbatch, the rotating shaft drives the cam to rotate. Under the action of the spring's rebound force, the contact plate is always in contact with the outer surface of the cam. The rotation of the cam drives the sliding column to slide back and forth through the contact plate. Due to the presence of gears and racks, the rotating rod slides while driving the actuating plate to rotate back and forth around the rotating rod, thereby scraping the masterbatch on the screen and preventing the masterbatch from accumulating and clogging the screen, thus affecting the normal operation of the screening process.

The lower end of the outer surface of each rotating rod 32 is provided with symmetrically distributed deflecting plates 33. The front end of each sliding column 31 is provided with a contact plate 34. A rotating shaft 35 is rotatably connected to the front side of the screening machine 1. The outer surface is fixedly fitted with cams 36 corresponding to the contact plates 34. The outer surfaces of the cams 36 are in contact with the front side of the adjacent contact plates 34. The front side of the screening machine 1 is equipped with a motor 4. The left end of the output shaft of the motor 4 is fixedly connected to the right end of the rotating shaft 35. The input end of the motor 4 is electrically connected to the output end of the microcontroller 2. The anti-blocking mechanism 3 also includes a spring 37. The front end of the outer surface of the sliding column 31 is movably fitted with a spring 37. The spring 37 is located between the rear side of the adjacent contact plate 34 and the front side of the screening machine 1.

[0024] The anti-blocking mechanism 3 also includes a guide assembly 38, which includes a limiting plate 381, a limiting groove 382, ​​a gear 383, and a rack 384. The screening machine 1 has a screening chamber 5 inside. The top wall of the screening chamber 5 is provided with a limiting groove 382 corresponding to the sliding column 31.

[0025] The working principle of this utility model is as follows:

[0026] The workers feed the granulated masterbatch into the screening machine 1 through the feeding port. The masterbatch falls onto the screen 7. The microcontroller 2 turns on the motor 11. The output shaft of the motor 11 drives the cam 10 to rotate through the rotating shaft. Under the restriction of the limit rod 9, the rotation of the cam 10 drives the screen 7 to move up and down along the slide 8 through the mounting frame 6. Under the vibration of the screen 7, the masterbatch with the correct particle size passes through the screen 7 and falls into the collection box, waiting for the workers to collect it. Because the mounting frame 6 is tilted with the left side higher than the right side, the masterbatch with the larger particle size flows out from the right side of the screening machine 1 along the tilted screen 7.

[0027] At the same time, motor 4 is turned on, and the output shaft of motor 4 drives cam 36 to rotate through shaft 35. Under the action of the spring 37, while cam 36 is rotating, the front side of contact plate 34 is always in contact with the outer surface of cam 36. The rotation of cam 36 drives slide column 31 to slide back and forth through contact plate 34, causing rotating rod 32 to slide along with it. Due to the presence of gear 383 and rack 384, rotating rod 32 drives actuating plate 33 to rotate back and forth around rotating rod 32 while sliding along limiting groove 382, ​​thereby scraping the masterbatch on screen 7 and preventing the masterbatch from accumulating and clogging screen 7.

[0028] It is worth noting that the microcontroller 2 disclosed in the above embodiments can be an STM32L1, and the motor 4 and motor 11 can be Y180L-615. The microcontroller 2 controls the operation of motor 4 and motor 11 using methods commonly used in the prior art.
