This invention belongs to the field of sandpaper production technology, specifically relating to a lamination and packaging system and method for dust-free ceramic dry sandpaper. The invention features a pre-assembly mechanism, a sandpaper feeding mechanism, a release liner feeding mechanism, and a lamination and packaging mechanism working collaboratively. The sandpaper and release liner feeding mechanisms respectively achieve precise, non-adhesive, and quantitative material delivery in a single layer, with precise material alignment achieved through a positioning structure. The pre-assembly mechanism utilizes vacuum adsorption and mechanical pressure to pre-assemble the double-layer sandpaper with the release liner, avoiding direct friction damage to the abrasive layers. The lamination and packaging mechanism employs a circumferential ring-shaped film formed by adhesive coating and curing. This invention effectively solves the problems of sandpaper shedding, scratches, and dust accumulation during the packaging process of high-hardness ceramic abrasive sandpaper, ensuring the performance of dust-free sandpaper, significantly reducing the cost of lamination and packaging consumables, and offering high efficiency and excellent alignment accuracy in automated assembly and lamination operations. It is suitable for the standardized mass production of high-precision dust-free ceramic dry sandpaper.

The utility model discloses a plastic package sealing device, which relates to the technical field of sealing devices and comprises a sealing table, a connecting frame is fixedly connected to the top of the sealing table, and a position calibration mechanism is arranged on one side of the connecting frame. An electric cylinder drives a connecting rod to move downwards, so that L-shaped plates are located on the two sides of a packaging bag, a second electric push rod drives the L-shaped plates to move, the packaging bag is pushed to move through the L-shaped plates, position calibration of the packaging bag is achieved, the packaging bag is pressed and limited through a limiting piece, position deviation of the packaging bag during sealing is reduced, alignment precision during hot pressing is guaranteed, and deviation or incomplete sealing is avoided. The position, above the conveying rollers, of the packaging bag is limited through the guide frame, the fourth gear drives the third gear to rotate, the using direction of the draught fan can be adjusted, and cooling of the sealing position of the packaging bag can be accelerated through the draught fan and the cooling box.
