6. The automatic cover closing device for injection molding of milk powder covers as claimed in claim 5, further comprising a conveyor for conveying finished milk powder covers and a finished product removing mechanism for removing finished milk powder covers from the pre-closing mechanism and transferring the finished milk powder covers to the conveyor, the finished product taking and discharging mechanism consists of a taking and discharging sucker and a moving mechanism for controlling the pressing mechanism to move between the position right above the pre-cover closing mechanism and the position right above the conveying belt, the taking and unloading sucker is arranged on the bottom end surface of the cover closing pressing plate and sucks the inner side of the cover seat of the finished milk powder cover, the moving mechanism drives the cover closing pressing plate to move right above the conveying belt, and the taking and unloading sucker loosens the milk powder cover finished product to enable the milk powder cover finished product to fall on the conveying belt.
7. The automatic cover closing device for injection molding of milk powder covers as claimed in claim 6, wherein the moving mechanism comprises a traverse plate, a traverse cylinder and a drag chain, the cover closing cylinder is vertically mounted on the traverse plate, the traverse cylinder is horizontally mounted, a cylinder rod of the traverse cylinder is connected with the traverse plate, the traverse cylinder pushes the traverse plate to move between the position right above the cover positioning plate and the position right above the conveyer belt, one end of the drag chain is fixed, and the other end of the drag chain is fixedly connected with the traverse plate.
8. The automatic cover closing device for injection molding of milk powder covers as claimed in claim 7, further comprising a frame, wherein the product receiving and transferring mechanism, the pre-cover closing mechanism and the conveyer belt are sequentially arranged on the frame from the front end to the rear end, the turnover cylinder is arranged on the frame, the other end of the turnover plate is connected with a bearing seat, the bearing seat is arranged on the frame, the mounting substrate is fixed on the frame, the traverse plate is slidably arranged on the frame, the traverse cylinder is horizontally arranged on the frame, and one end of the drag chain is fixed on the frame.
