The effective width of the production line is wider and is mostly 3.5-4.5 meters. The above-mentioned hot size shaping is to regulate the temperature and hot air quantity to act on the non-woven fabric uniformly to stabilize the size. The drying refers to removing the water in the non-woven fabric after the mucilage is soaked and hung, and controlling the water in a standard water-containing range, and the used equipment is a multi-cylinder drying unit.

In the use process of the traditional shaping dryer (or machine set) cylinder structure, although hot air is uniformly delivered to the periphery of the cylinder, the difference between the effective air quantity and the air flow which penetrate through the cylinder is larger in the width direction, the suction force close to the air inlet machine side in the cylinder is larger, the hot air flow is larger, the left and right difference of the shaping effect of the cylinder structure finally acting on the non-woven fabric is obtained, or the difference exists for the drying effect. On the other hand, the traditional shaping dryer (or machine set) with a cylinder screen structure has small mesh diameter, and when the traditional shaping dryer (or machine set) is used for a period of time in a short period, part of the meshes are easily blocked by waste flocs and rubber blocks, so that the shaping or drying uniformity is influenced.

Furthermore, two ends of the inner layer rotary screen are fixed on the main shaft through support rods.

Furthermore, the number of the supporting rods at each end of the inner layer circular net is at least 3.

Furthermore, the two end sides of the inner layer rotary screen are respectively connected with a chuck through supporting rods and then fixed on the spindle through the chuck.

Further, the outer layer cylinder mould and the inner layer cylinder mould are both cylindrical.

Furthermore, the side surface of the outer layer cylinder is uniformly provided with screen holes.

Furthermore, sieve holes are uniformly formed in the cambered surfaces corresponding to the fabric wrap angles on the side surfaces of the inner layer circular net, and the rest cambered surfaces are not provided with holes.

Further, the diameter of the screen mesh of the outer layer cylinder mould is 3-4 mm.

Further, the diameter of the screen mesh of the inner layer rotary screen is 3-4 mm.

The utility model also provides a non-woven fabrics design drying-machine, non-woven fabrics design drying-machine adopts above-mentioned broad width design stoving cylinder.

Advantageous effects

The utility model relates to a broad width design stoving mould, structural design is novel unique. Through twice screen plate rectification of the outer layer and the inner layer, the air quantity penetrated by hot air in the width direction is uniform and stable, and the uniformity of the shaping and drying effects of the non-woven fabric is effectively ensured. The mesh diameter can be properly enlarged due to the addition of one-time rectification in the design of the mesh, so that the phenomenon that the mesh is easy to block is avoided or reduced. The inner layer cylinder is only provided with partial meshes according to the wrap angle size of the cloth cover and the cylinder, so that hot air is oriented to penetrate through the effective area only, and the use efficiency of the hot air is improved. The utility model discloses have very high practicality, be practical for the non-woven production line more than 3 meters of broad width very much, can make the fabric design drying even more, steady, high-efficient, be fit for extensively promoting.
