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 relates to a formaldehyde elimination agent and a preparation method thereof as well as an adhesive, a wooden product and an artificial board. The formaldehyde elimination agent comprises the following ingredients in parts by weight: 64-92.9 parts of pure water, 5-20 parts of urea, 2-15 parts of hydrazide compound and 0.1-1 part of an anionic surfactant. The formaldehyde elimination agent can be added into the adhesive and can be also sprayed on the wooden product and the artificial board. The formaldehyde elimination agent has the benefits as follows: on the basis of reaction between urea and formaldehyde, the hydrazide compound is added, so that the technical effect of no reverse reaction after reaction is realized; since the anionic surfactant is added, the reaction between effective ingredients in the product and formaldehyde in the artificial board is reinforced; the pH of the formaldehyde elimination agent is 7-9, the color of the wood material is not changed after the formaldehyde elimination agent is sprayed on the wood material with a light color, and the contents of formaldehyde in the adhesive, the artificial board and the wooden product reach the national compulsorily-executed health standard level.

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 deep layer foundation treatment method and foundation strengthening equipment formed through the method, and belongs to the field of foundation treatment. The problem that according to an existing dynamic consolidation method, a deep layer foundation is not pounded conveniently is solved. According to the technical scheme, the deep layer foundation treatment method and the foundation strengthening equipment formed through the method are characterized in that a drying agent, a gap filling agent, a water passing expansion rubber layer and a rubble layer are sequentiallyadded in the deep layer foundation, and finally the foundation strengthening equipment is used for conducting strengthening treatment on the deep layer foundation. The deep layer foundation treatmentmethod and the foundation strengthening equipment formed through the method have the beneficial effects that the firmness and the cost performance of the deep layer foundation are high.
