The main structure and technical characteristics of cosmetics sorting machine
1. It is composed of main and driven rollers, belt weighing conveyor, servo motor, frame, etc. The main and driven rollers are designed with a drum structure to effectively prevent belt deviations. At the same time, the driven roller needs to be tested for dynamic balance The deviation from the level 6.3 G (0.3 G) avoids the main shock and the dynamic imbalance caused by the cylinder vibration to the weighing measurement. The weighing conveyor is driven by a servo motor, and the operating speed of the conveyor can be adjusted in time according to the length of the workpiece to be inspected, throughput and other parameters to ensure that only one product conveyor platform is weighed. The servo motor and the driving roller are driven by a synchronous toothed belt, which is stable and noise-free. The belt of the weighing conveyor is equipped with a V-shaped groove guard plate, which can effectively prevent the cylindrical product from rolling during the conveying process, and ensure the stability and accuracy of weighing and measurement. The weighing conveyor is equipped with a windshield to prevent the influence of external wind on the weighing and measurement, and to prevent people from contacting the weighing conveyor and affecting the weighing and measurement. The mortise structure design is adopted between the weighing conveyor and the frame, with fixed buckles, quick release, and convenient cleaning and maintenance of the conveyor. The main roller and the driven roller of the weighing conveyor are equipped with photoelectric detection switches to detect whether the product completely enters the weighing conveyor and whether to leave the weighing conveyor to ensure that the entire product is weighed and measured. And to ensure the accuracy of weighing. 2. The structure of the feed product sorting machine and the unloading conveyor are the same as the weighing conveyor, but the dynamic balance test of the main roller and the driven roller is not performed. 3. The weighing module adopts a fully enclosed structure design, which is connected through the bottom shell and load cell. The bottom shell under the load cell is connected with overload protection bolts. The assembly of the weighing module needs to be tested after the ballast is completed. Increase the load to the rated load, the load of the load cell is output to 2 mv, and the overload protection is carried out by adjusting the bolt. If the load continues to increase above the rated load, the output millivolt value of the load cell. The load cell adopts the HBM PW6KRC3 single-point load cell, and the larger scale size is 300mm×300mm. 4. Elimination method According to the weight and throughput of the product, you can choose the blowing type or the cylinder push rod type. For products weighing less than 500g, you can choose the blowing type. The blowing type elimination structure is simple and efficient. The elimination device is fixed on the discharge conveyor, and unqualified products (overweight and overweight) are classified by weight. As shown in Figure 2, multiple sets of rejection devices can be used to make the unqualified products enter the corresponding collection boxes respectively. The collection box of unqualified products is designed with a fully enclosed structure, and the collection box is equipped with a reclaiming door and a discharge port. Lock. The designated person is responsible for ensuring that nonconforming products are effectively managed. 5. When receiving the operating signal of the user's production line, the electrical control system will automatically start and run. At the same time, if a fault alarm occurs on the cosmetics online weight check scale, the fault information will be fed back to the user control system of the production line. When the photoelectric switch of the feeding conveyor detects the product, it runs the cosmetics online weight check scale to weigh and measure the product online, and remove the unqualified product from the production line through the rejection device. The statistical results of the weight detection have real-time feedback adjustment signals to control the packaging weight of the product.
