Abstract
Description
Technical Field
[0001] The utility model relates to a screening device, in particular to a finished bamboo chopstick grading and screening device. Background Art
[0002] During the production process of bamboo chopsticks, it is necessary to screen and classify the bamboo chopsticks produced centrally on the production line according to different sizes, shapes, types and quality levels to ensure the consistency of the products delivered to customers in the later production and shipment process.
[0003] Conventional screening equipment usually sets up channels of different diameters during the transmission of bamboo chopsticks. When the bamboo chopsticks pass through, bamboo chopsticks of corresponding diameters will fall into the channels. Through this screening method, bamboo chopsticks with large size differences can be quickly screened in batches. However, when the bamboo chopsticks are of similar sizes, the mechanically set drop frame cannot accurately screen the bamboo chopsticks of similar sizes, resulting in mixing of materials. The consistency of screening cannot be guaranteed, and manual sorting is required, which is inefficient. Utility Model Content

When the bamboo chopsticks fall into the blanking frame 5, they will slide to the side away from the material transfer frame 4, and the blanking frame 5 is provided with a square blanking hole on the side away from the material transfer frame 4. When the bamboo chopsticks slide into the hole, they will fall downward. A bracket 6 is fixedly welded to the left side of the top of the material transfer frame 4, and a detector 61 is installed on the bracket 6. A cylinder 7 for performing the screening action is installed on the blanking frame 5, and the movable rods of the cylinder 7 all pass through the blanking on the same side. Frame 5, and the upper part of the movable rod of the cylinder 7 are fixedly installed with a push rod 71, the position of the push rod 71 is slightly lower than the height of the upper part of the screw rod 31, the detector 71 is a visual detector, and the bamboo chopsticks transmitted to the left in the material frame 4 are scanned. The detector 71 is externally connected to a control console, and the control console has preset data of bamboo chopsticks of different sizes. When the detector 61 scans the transmitted bamboo chopsticks, the scanned view is transmitted to the control console for data comparison and feedback to the cylinder 7, and the cylinder moves.
[0019] Initially, the movable rod of the cylinder 7 is in a retracted state, and the motor 32 rotates to drive the screw rod 31 to rotate. Figure 4, there will be a sequence of workpieces 100 that need to be screened in the thread of the screw rod 31, and it will be transmitted to the left under the drive of the motor 32. When the bamboo chopsticks move under the detector 61, the detector 61 will scan the size of the bamboo chopsticks and feed back the value to the cylinder 7. When the bamboo chopsticks after detection move to the top of the push rod 71, the cylinder 7 will push out one of the two push rods 71 according to the data of the detector 61 according to the transmitted size of the bamboo chopsticks. When the push rod 71 is pushed out, one end of the bamboo chopstick will tilt up, the center of gravity of the bamboo chopstick will shift, and it will slide to the other tilted end and slide into the corresponding blanking frame 5 below. The bamboo chopsticks are blanked and sorted through the blanking frame 5. According to the above-mentioned device structure and screening method, it can be correspondingly known that the device can flexibly set a corresponding number of blanking frames 5 according to needs and bamboo chopstick size classification, so as to screen bamboo chopsticks of not limited to two sizes, and set multiple blanking frames for diverting and screening the bamboo chopsticks.
[0020] Embodiment 2: Based on embodiment 1, Figure 1 and Figure 4 As shown, it also includes a support frame 29, a detector 291, a cylinder 210 and a push plate 11.
