[0051] The preferred embodiment of the utility model further provides a chip plastic packaging device, which includes the above-mentioned automatic resin clearing hopper.
[0052] The working principle of the resin automatic cleaning hopper of the preferred embodiment of the utility model is as follows:
[0053] 1. Under normal conditions, the sliding plate 12 is located at the first position, and the sliding plate 12 can block the feed port 1151. The staff adds resin into the bucket 11 through the feed port 1131, and the resin rolls from a high position to a low position along the bottom plate 115. When the resin passes through the sliding plate 12, the smaller particles of the slag can be leaked to the bottom through the perforation 121, and the resin at the lower part of the bottom plate 115 can be loaded through the loading structure 114;
[0054] 2. When it is necessary to remove the resin in the bucket 11, the staff can place the material collecting device for collecting the resin under the material guide outlet 142, and the driving structure 13 pulls the sliding plate 12 to the second position, and the discharge port 1151 opens. Since the discharge port 1151 is located at a lower position, the resin can fall out of the discharge port 1151 and enter the material guide structure 14 through the material guide inlet 141, and finally fall into the material collecting device through the smaller material guide outlet 142.
[0055] This completes the working principle of the automatic resin cleaning hopper of the preferred embodiment.
[0056] The utility model discloses an automatic resin cleaning hopper and chip encapsulation equipment. Under normal conditions, the sliding plate is located at the first position, and the sliding plate can block the feed port. The staff adds the resin into the hopper through the feed port. The resin rolls from a high place to a low place along the bottom plate. When the resin passes through the sliding plate, the smaller particles of debris can be leaked to the bottom through the perforations. The resin located at the bottom of the bottom plate can be loaded through the loading structure. When the resin in the hopper needs to be cleared, the driving structure pulls the sliding plate to the second position, and the feed port is opened. Since the feed port is at a low position, the resin can fall out of the feed port. The utility model discloses an automatic resin cleaning hopper and chip encapsulation equipment. The resin can automatically clear the remaining resin and filter out the debris during operation. The resin is easy to use and effectively improves the work efficiency.
