By setting a shoe edge correction step, burrs and gluing at the shoe edge of a prepared shoe are treated by adopting a correction tool and the problems of the burrs and the gluing of the shoe edge of the finished-product shoe are avoided.

The invention relates to a trimming knife after film coating of a plastic product film coating combination machine, comprising a rack, an upper blade, a lower blade, a blade adjusting mechanism and a driving mechanism, wherein the upper blade and the lower blade are disc-shaped and are respectively arranged on the rack by an upper knife rest and a lower knife rest; an elastic blade adjusting device for adjusting the blades is also arranged between the lower blade and the lower knife rest and comprises at least three springs; the lower knife rest is provided with hole grooves for installing the springs; and the springs are arranged in spaces formed by matching of the hole grooves and the lower blade and are in a compressed state. The trimming knife has the advantages that the distance between the upper blade and the lower blade is adjusted by the elastic blade adjusting device, so that the upper blade and the lower blade are attached together all the time, and further the problem of film-coating material burrs or incomplete cutting caused by separation of the upper blade and the lower blade is solved.

The invention belongs to a method for forming a cement decorative plate with deep concave and convex patterns by adopting mold box overlapping and vertical vibration. Forming mold boxes comprise a movable mold box and a forming machine mold box which are overlapped, the movable mold box comprises a mold frame and a plastic mold box loaded in the mold frame, and the plastic mold box comprises an outer hard plastic box and an inner elastic soft plastic box; a vibrator is arranged at the upper part of a press head of a forming machine, and a vibrating table at the lower part of the forming machine and the vibrator at the upper part of the press head are started simultaneously during vibrating. With the adoption of the method, the problem about demolding of the deep concave and convex decorative surface can be solved very well, and the problem about forming compaction when the inner elastic soft plastic box is used by a cement mixing material is solved.

The invention provides a novel angle lifter base applied in a mold, which comprises a sliding block, wherein the sliding block is movably embedded in an upper top plate of the mold, one end of an angle lifter is fixed on the sliding block, and the other end is matched with a core insert and a cavity insert of the mold for molding a product. Preferably, the invention provides the novel angle lifter base, wherein the sliding block is a cylinder. The angle lifter base can reduce the strength weakening effect of the angle lifter of the mold to the upper top plate, thereby avoiding the problem of burrs or more adhesive of the product due to inadequate strength of the upper top plate and having excellent practical value.

The invention relates to a thin film material cutting device. The thin film material cutting device comprises a machine frame with the supporting function, a first roller shaft, first gears, a secondroller shaft and second gears, wherein the first gears are coaxially arranged on the first roller shaft, and the second gears are coaxially arranged on the second roller shaft. According to the thin film material cutting device, before cutting, a thin film material is placed between the first roller shaft and the second roller shaft, the first roller shaft and the second roller shaft rotate so that cutting blades can be matched with annular grooves, and therefore the thin film material can be cut; moreover, the radius of each first gear is smaller than the radius of each second gear, so that the rotating speed of the first roller shaft is higher than the rotating speed of the second roller shaft, that is, the rotating speed of the cutting blades is higher, so that the speed difference between the cutting blades and the thin film material is larger; at the moment, the higher the cutting speed of the cutting blades is, the better the cutting effect of the thin film material is; and therefore the thin film material cutting device can effectively prevent the occurrence of burrs when the thin film material is cut.

The invention discloses a sandwich fabric bra mould cup for female sports underwear and a manufacturing technology. The sandwich fabric bra mould cup comprises a mould cup body and an edge covering layer, the mould cup body comprises at least one sandwich fabric layer, and the edge covering layer and the external circumferential side face of the mould cup body are hot-pressed into a whole in an adhesive spraying and bonding manner through adhesives. The manufacturing technology includes the steps: equipment installation; sandwich fabric preparation; mould cup sizing and transferring; edge covering layer adhesive spraying, bonding and hot-pressing; mould cooling and pressing; finished product detection. A mesh layer in a sandwich fabric layer can be effectively fixed, and raw edges are prevented from being formed at the edge of the bra mould cup, easily itching skins and causing wearing discomfort. The manufacturing technology with the simple steps is high in practicability. Compared with an existing bra mould cup with sewn covering edges, the bra mould cup manufactured by the technology can be rapidly restored to an original shape even if the bra mould cup deforms, raw edge piercing cannot be caused in long-time use and cleaning, wearing effects cannot be affected, assembly line processing production requirements can be met, and manufacturing cost is reduced.

The lifter set system also comprises an ejector pin, wherein one end of the ejector pin is fixed on a top plate on the die, and the other end is abutted against the top block. The invention can reduce the strength influence of a lifter set on the upper top plate, avoid the problem of burr or excess glue caused by insufficient strength of the top plate and have more favorable practical value.

A heat dispersion encapsulation structure and its method are provided, which is characterized in that: place and connect a semiconductor wafer to a wafer bearing component; position a heat dispersion component with a interference face layer on its surface on the semiconductor wafer, so as to form a complete encapsulation glue body that wraps the semiconductor wafer and the heat dispersion component; then, cut the wafer bearing component and the encapsulation glue body according to the preset dimension of the encapsulation structure and form a bevel at the top brim of the encapsulation glue body, so as to partially expose the brim of the heat dispersion component; then, remove the encapsulation glue body on the interference face layer and form the encapsulation glue body that covers the interference face layer by keeping a spacing elevation between the encapsulation glue body and the top face of the interference face layer. Meanwhile, because the cutting path of the cutting operation does not pass the heat dispersion component, the invention is able to prevent the problem of flash and wearing of cutter due to the direct cutting of the heat dispersion component by the cutter, thus reducing the cutting cost.
