Description

Technical Field

[0001] This invention relates to the field of PC / ABS alloy and PC masterbatch production, specifically to an online color difference detection and circulating feeding device and its usage method. Background Technology

[0002] Current PC / ABS alloy and PC masterbatch production involves manually lifting the mixed PC, ABS, and color powder through stairs into a hopper over 2 meters high. After masterbatch production, a large amount of PC is needed to clean the residual color powder from the screw extruder to prevent it from affecting subsequent masterbatch production.

[0003] However, manual high-altitude material loading has several drawbacks:

[0004] 1. Frequent material loading during high-altitude operations can easily lead to falls and injuries to personnel;

[0005] Second, manual feeding can easily cause materials to fall from a height, damaging high-speed operating equipment.

[0006] Meanwhile, there are several shortcomings in equipment cleaning after the production of PC / ABS alloys and PC masterbatches:

[0007] First, it requires the consumption of a large amount of materials;

[0008] Second, frequent manual loading of materials poses a danger to working at heights.

[0009] Third, the accuracy of manual visual inspection in determining the cleaning effect leads to unstable production quality in subsequent batches of products. Summary of the Invention

[0010] Therefore, in order to overcome the above-mentioned shortcomings, the present invention provides a device with a reasonable design, ingenious structure, and easy maintenance for the production of PC / ABS alloys and PC masterbatches. This device is used for online inspection of color difference in the production of PC / ABS alloys and PC masterbatches and for feeding the production equipment. It has high production efficiency, high safety, high reliability, and stable product quality.

[0011] This invention is implemented by constructing an online color difference detection and circulating feeding device, comprising:

[0012] The discharge conveyor belt is installed below the discharge port of the production equipment;

[0013] The testing conveyor belt is located at the discharge end of the discharge conveyor belt, and several sampling bases made of metal are fixedly installed on the testing conveyor belt; the sampling bases are detachably connected to the testing conveyor belt.

[0014] An online detector, installed above the detection conveyor belt, performs color difference detection on samples within the sampling matrix;

[0015] The material distribution conveyor belt, located at the discharge end of the inspection conveyor belt, transports the inspected materials; and

[0016] Lifting conveyor belts are used to feed materials into production equipment.

[0017] Preferably, it also includes a control box, which is connected to the lifting conveyor belt, the discharge conveyor belt, the detection conveyor belt, the distribution conveyor belt, and the online detector.

[0018] Preferably, it also includes a scraper, which is installed in front of the online detector to scrape the material in the sampling substrate that is about to be input into the online detector.

[0019] A metal sensor is installed behind the scraper.

[0020] Preferably, it also includes a bracket for mounting the control box, wherein the online detector is mounted on the side wall of the control box and is height-adjustable, the purpose of which is to adjust the inspection accuracy of the online monitor; the bottom of the bracket is a base.

[0021] Preferably, the online detector includes a mounting body and a color difference detector mounted on the mounting body with the probe facing downwards, the mounting height of the color difference detector being adjustable.

[0022] Preferably, the mounting body has mounting holes for mounting a color difference detector.

[0023] Two vertical mounting tenons are provided on the front and rear outer walls of the mounting body, and mounting tenons matching the mounting tenons are provided on the inner outer wall and the front and rear outer walls of the control box.

[0024] The mounting body is equipped with fixing screws for securing its position.

[0025] The upper end of the color difference detector extends through the mounting body, and a large fixing screw for fixing the position of the color difference detector is installed on the mounting body.

[0026] A method for using an online color difference detection circulating feeder includes the following steps:

[0027] ① The material output from the discharge port of the production equipment is transported to the testing conveyor belt via the discharge conveyor belt, during which the material falls into the sampling substrate;

[0028] ② The sampling substrate containing the material is conveyed by the detection conveyor belt. When the sampling substrate reaches the scraper, the material in the sampling substrate is scraped flat by the scraper. At the same time, when the metal sensor detects the sampling substrate made of metal, the detection conveyor belt slows down / stops. The color difference detector judges the color difference of the material in the sampling substrate. After the judgment, the detection conveyor belt continues to work. The color difference judgment result is either pass or fail.

[0029] ③ When the color difference judgment is passed, the material distribution conveyor belt rotates forward, and the material conveyed by the detection conveyor belt is lifted to the feed inlet of the production equipment by the lifting conveyor belt to realize the cyclic feeding;

[0030] When the color difference judgment fails, the material distribution conveyor belt reverses and transports the material conveyed by the detection conveyor belt to the designated reverse device.

[0031] In step ②, the distance between the probe of the color difference detector and the sampling substrate is adjustable, thereby adjusting the detection accuracy of the color difference detector in sequence.

[0032] The present invention has the following advantages:

[0033] This invention is reasonably designed, ingeniously structured, and easy to maintain. It is used for the production of PC / ABS alloys and PC masterbatches, enabling online inspection of color differences in the production of PC / ABS alloys and PC masterbatches, as well as feeding of production equipment. The lifting conveyor belt, discharge conveyor belt, inspection conveyor belt, and distribution conveyor belt are all controlled by servo motors, allowing for forward and reverse rotation and speed adjustment, which facilitates material transportation.

[0034] The sampling substrate is made of metal and is installed on the conveyor belt in a detachable manner (such as by threaded connection), which facilitates disassembly and replacement and makes maintenance convenient.

[0035] Meanwhile, the scraper is detachable and replaceable, and its position can be adjusted up and down to adapt to different sampling bases, making it more adaptable; at the same time, the metal sensor is detachable and replaceable, which is convenient for maintenance.

[0036] The online detector is detachable and replaceable, and its position can be adjusted up and down, making it easy to install and disassemble. It can also adapt to the transportation and installation of online detectors in different directions. The color difference detector in the online monitor is detachable, making it easy to install and allowing for the replacement of color difference detectors of various specifications.
