[0014] The following are specific embodiments of the present utility model in combination with the drawings to further describe the technical solutions of the present utility model, but the present utility model is not limited to these embodiments.

[0015] Embodiment

[0016] As Figure 1-2 shown, a grain ejector device of a KGD sorter includes a fixed bracket 2. One side of the fixed bracket 2 is provided with a lifting mechanism 3. The other side of the lifting mechanism 3 away from the fixed bracket 2 is provided with an installation frame 4. The lower part of the installation frame 4 is provided with a first driving motor 5, and its driving end is provided with a driving structure connected thereto. The other end of the driving structure away from the first driving motor is connected to an eccentric wheel 9 installed inside the installation frame 4. The top of the installation frame 4 is provided with an ejector seat vacuum adsorption mechanism 1, and the lower part of the ejector seat vacuum adsorption mechanism 1 is provided with a roller 10 that matches the eccentric wheel 9.

[0017] In this embodiment, the lifting mechanism 3 includes a fixing plate provided at its lower end. One side of the fixing plate is provided with a second driving motor 11. The second driving motor 11 drives the lifting mechanism 3, so that the whole lifting mechanism rises and falls, and at the same time drives the installation frame 4 to rise and fall.

[0018] The driving structure is composed of a driving wheel 6, a driven wheel 7 and a transmission belt 8. The other end of the driven wheel 7 away from the driving wheel 6 is connected to an eccentric wheel 9. The upper end of the roller 10 is provided with a jacking rod 13, and the jacking rod 13 is arranged in the inner cavity of the ejector seat vacuum adsorption mechanism 1. Through the setting of the eccentric wheel 9, when it rotates, it can perform a jacking action on the jacking rod 13.

[0019] The ejector seat vacuum adsorption mechanism 1 includes an ejector seat 12 and an ejector fixing magnetic base 14 provided on its upper part. The ejector fixing magnetic base 14 is provided with a core grain ejecting ejector 16. The upper end of the ejector seat 12 is provided with an ejector cap 16. The ejector fixing magnetic base 14, the core grain ejecting ejector 16 and the jacking rod 13 are all arranged in the inner cavity of the ejector cap 16.

[0020] After the product film is expanded in place, the pick-up nozzle contacts the die. The lifting mechanism raises the ejector pin seat, and the ejector pin cap contacts the bottom of the die fixing tape. The vacuum adsorption mechanism is turned on to adsorb the tape at the bottom of the die, fixing the tape at the bottom of the die. The ejector pin lifting mechanism ejects, causing the ejector pin to eject the die, and cooperates with the die pick-up nozzle to successfully pick up the die. After the picking is completed, the ejector pin descends, the vacuum mechanism releases the vacuum, and the ejector pin seat mechanism descends to complete the operation of a single die.
