According to the technology, the automatic production of the sound absorption board to be lifted and conveyed becomes possible, the rejection rate of the sound absorption board is effectively reduced, the appearance quality of the product is improved, the production cost is reduced, and the economic benefit of enterprises is improved.

Description

A kind of pallet of applying in the production process of abatvoix and production technology thereof

Technical field

The present invention relates to and be a kind ofly applied to the pallet in abatvoix production process and manufacture the production technology of this pallet.

Background technology

Abatvoix is a kind of house decorative material reducing noise, and in the middle of prior art, the material such as expanded perlite, mineral wool, rock wool, glass silk floss, foaming aluminum, foamed ceramic, wood fiber, perforating gypsum board is the common used material manufacturing abatvoix.For expanded perlite, because its porous, lightweight, fire prevention, the characteristic such as high temperature resistant, nontoxic belong to green structural material, it is that heat energy reduces noise by the kinetic transformation produced by sound wave.But, because expanded perlite is frangible, therefore, often there will be breakage at production link and cause reject rate to increase.

Manufacture in the production process of abatvoix at expanded perlite, after the process procedure such as cloth, compacting, abatvoix will be sent in dry kiln and carry out drying and processing, generally by load-transfer device or roller-way by abatvoix from compacting link deliver to dry kiln dry after from dry kiln, enter inspection chamber by load-transfer device or roller-way again and to test packaging.And in this production process, due to the frangibility of expanded perlite itself and its be heated uneven in dry kiln, when abatvoix from dry kiln out time, often there is broken angle phenomenon and finished product reject rate improved, too increasing productive costs thereupon.

Summary of the invention

For prior art Problems existing, present invention employs the hollow pallet of a kind of metal as entering into dry kiln at abatvoix and enter into the accessory appliances of this flow process of control laboratory after pressing process after dry kiln drying process.This pallet adopts metal material to make, reduce costs to save the usage quantity of metal, and consider the factors such as the thermal loss that heat absorption brings, metal material can make hollow structure, and the shape of this metal tray can design the shape need of abatvoix according to user.

The invention still further relates to the manufacturing process of this metal tray, hollow bonding jumper is made the shape with abatvoix shape adaptation to be processed by techniques such as cutting, welding, polishing, surface treatments.

The invention still further relates to and use the method for this metal tray, by chemical treatment, avoid due to ferrous metal pallet oxidation and rusting and impact of producing for abatvoix surface quality in high temperature and air.

Detailed description of the invention:

Below by conjunction with the embodiments and accompanying drawing specifically set forth technical scheme of the present invention.

In actual production process, the shape of abatvoix is generally rectangle, and different according to the demand of client, the shape of abatvoix can also relate to various

Geometric figure, such as: triangle, rhombus, circle, ellipse, polygon (limit number is more than or equal to 4) etc.The pallet of abatvoix therefore involved in the present invention also should be suitable with mentioned geometric configuration in user's request.And the material forming pallet can be resistant to elevated temperatures metal or non-metallic material, in actual mechanical process, the temperature of abatvoix is processed between 100-300 DEG C in dry kiln, therefore, when selection pallet material, that should consider that this metal or non-metallic material can not melt distortion or occur that other chemical reaction has influence on pallet in the scope of 100-300 DEG C lifts effect.In actual production, corrosion-resistant steel, iron, aluminium, copper material, alloy material, PPS, nylon, carbon fiber, pottery, sytull etc. are all applicable to the material of pallet of the present invention.Taking cost into account, preferred irony material is comparatively economical.

As shown in Figure 1, for rectangular tray, it can adopt the configurations such as lattice-shaped distribution, the distribution of order shape, the distribution of matts shape, the distribution of checked spun antung shape, the distribution of double check with a core shape, the distribution of Back Word trellis.Compared with traditional sealing bottom type pallet, have employed the pallet of above-mentioned configuration, its heat transfer is better, recepts the caloric less, and minimum to the heat affecting of abatvoix in whole use procedure, and work efficiency is the highest.Little owing to recepting the caloric, work efficiency is high, so lower to the energy input in dry kiln, can be that enterprise is cost-saving, and, due to the power of lifting of pallet and the existence of above-mentioned various pattern mode, make the stress that is distributed on abatvoix comparatively even, heat is also comparatively even, therefore, do not exist uneven due to abatvoix local heating and cause breakage, deformation, the problem such as to burst.And after adopting above-mentioned pattern, also do not need to adopt too much pallet material just can reach industry necessary requirement, also cost-saving to a certain extent.

As shown in Fig. 2 (a-b), the cross section of abatvoix pallet is the structure of hollow, this structure has following advantage: compare relative to the pallet of solid material, the material that it is saved, and greater advantages are, the process heat absorption that the material of this hollow makes this pallet enter into dry kiln at carrying abatvoix is few, compare relative to the pallet of the solid material of equivalent specifications, caloric receptivity will lack about 75%, and so a large amount of heats is avoided consumption, for industry energy conservation environmental protection, is lowered into and originally says and be significant.In addition, adopt hollow material to make whole pallet lighter in weight, greatly alleviate and have bad luck personnel's physical demands, labour intensity also decreases.

Be illustrated in figure 3 pallet hollow material section drawing

According to Fig. 4, displaying be from being pressed into dry kiln, then from dry kiln to control laboratory this use pallet process in technological process.

Be the manufacturing process setting forth this pallet for rectangle according to Fig. 5 (a-e), what Fig. 5 a represented is hollow metal tube, through cutting, obtains and can manufacture the material with the suitable size of abatvoix size.Material after what Fig. 5 b showed is by cutting is with positioning configurations on the platform of frock.Fig. 5 c is shown the welding method commonly used by spot welding or other this area and welds with solid shape.What Fig. 5 d showed is shaping after the polishing of pallet, smoothing or glossing, Fig. 5 e, according to the requirement of actual production environment or user, can carry out as plated film, plating, spraying, mopping to the pallet after configuration, the process of surface treatment such as turn blue.

Adopt easy oxide etch material, such as, chemical maintenance technology during irony pallet.For the pallet of irony, the corrosion such as ferric oxide or ferrous oxide can be produced through long high temperature, high humidity and oxidation, and the generation of iron rust can pollute to abatvoix, and also can affect the service life of self, contriver has found to avoid because corrosion reason impacts the method for product design through experiment for this reason.

Adopt water glass solution process irony tray surface, the generation of the problems referred to above can be avoided.The proportioning of water glass solution: water glass solution glass magnesium density 15-40 degree; The cycle of process: 6 months-2 years; The mode of process: water glass solution is evenly coated with, sprays or wipes on pallet, enter drying chamber after natural seasoning and dry 10 minutes, after taking-up, tray surface is polished smooth, totally, can use.
