Production equipment of foam laminated packaging box blanks includes a longitudinal creasing device, a transverse creasing device and a traction mechanism. A foam laminated plate is driven forward bythe traction mechanism; when the foam laminated plate passes by the longitudinal creasing device, deep longitudinal creases are made in the foam laminated plate; when the foam laminated plate passes by the transverse creasing device, deep transverse creases are made in the foam laminated plate; the longitudinal and transverse creasing devices which are of special structures enable the longitudinaland transverse creases, which are made, to never bounce back, and breaking of the foam laminated plate is avoided.

The invention relates to a multifunctional pot cover. A fixed cover of the multifunctional pot cover is fixed to an opening of a pot body, a sealing opening structure corresponding to the fixed coverin shape is arranged on the fixed cover, the back side of a movable pot cover is connected with the upper portion of the back side of the fixed cover through a connecting mechanism, a lock catch structure is arranged on the front side of the fixed cover, a fixing block is arranged on the front side of the movable pot cover, a bouncing mechanism is arranged in a support on the back side of the fixed cover, and a clamping block is arranged on the back side of the movable pot cover. The multifunctional pot cover is fixed to the corresponding pot body, can be used together with the pot body and can also be used in cooperation with various pot bodies, the pot cover is provided with an external lock catch, the bouncing mechanism is arranged inside, a rubber cover is completely closed due to thefact that the lock catch device is arranged outsides, the sealing degree is high, the pot cover overall structure is a rectangular structure, the bottom can be provided with a traditional cylindricalpot body or pot bodies of other structures, in the transporting process, contact faces between the pot covers are planes, and therefore swing is not prone to occurrence.

The invention provides a production process of a double-faced woolen product. The production process includes the steps of a, weaving; b, steaming, to be more specific, steaming the woven double-facedwoolen product; c, napping, to be more specific, using a teasel gig to perform napping on the steamed double-faced woolen product; d, sewing, to be more specific, sewing after folding in the width direction; e, washing, to be more specific, washing the sewn double-faced woolen product with a softener; f, dewatering, to be more specific, subjecting the washed double-faced woolen product to dewatering; g, drying, to be more specific, drying the double-faced woolen product at set temperature; h, cutting off floating wool, to be more specific, cutting off the floating wool on the surface of the dried double-faced woolen product; i, ironing, to be more specific, repairing the defects of the double-faced woolen product after floating wool cutting, and then ironing. The production process has the advantages that three-colored yarn is guided into a rotary drum before weaving, and the produced double-faced woolen product is rich in color and attractive in appearance.

The invention provides a PCB welding method. The PCB welding method comprises the steps of a, completely stripping a sheath on an electric wire; and b, welding the stripped copper wire of the electricwire on a PCB. According to the invention, the sheath on the electric wire is completely stripped without damaging an internal copper wire, and meanwhile, the stripped electric wire sheath is not adhered to the copper wire and does not rebound, so that the welding of the electric wire is not influenced. Parallel connection of the electric wire and a PCB can realize only by designing the conventional bonding pad according to the conventional specification. In this way, the production efficiency can be greatly improved, the product tension is increased, and the attractiveness is improved.

The invention discloses a bicycle elbow device comprising a bottom plate, an elbow mold, a pneumatic cylinder, a first hydraulic cylinder, a second hydraulic cylinder and a bicycle head fixed seat, wherein the elbow mold is fixed on the bottom plate, the first hydraulic cylinder and the bicycle head fixed seat are fixed on the bottom plate at the right side of the elbow mold, the pneumatic cylinder and the hydraulic cylinder are fixed on the bottom plate at the left side of the elbow mold, a positioning block adaptive to the head of the elbow is arranged on the pneumatic cylinder, a compression block adaptive to the surface of the elbow is arranged on the first hydraulic cylinder, and a buckling device is arranged on the second hydraulic cylinder. The bicycle elbow device has the advantages of being capable of setting holding-up time according to performances of a straight pipe, and further keeping no bouncing of the bent elbow, and ensuring the product quality.
