Abstract

The utility model discloses a hot roll structure used for non-woven cloth production. The hot roll structure used for non-woven cloth production comprises an upper roller, a low roller parallel to the upper roller. A supercharging circulation channel is arranged on the internal side of the circumference of the lower roller. The supercharging circulation channel comprises an upper half portion and a lower half portion, wherein both half portions are independent from each other. The right end of the lower half portion is an oil inlet, and the right end of the lower half portion is connected with the left end of the upper half portion. The right end of the upper half portion is an oil outlet. The hot roll structure used for non-woven cloth production has the advantages that the reliability of the structure in operation is greatly improved, the heat bonding is guaranteed, a problem that slow cloth feeding is caused by frequently adjusting the speed of feeding cloth due to the fact the ejected quantity of the lower roll is insufficient and the heat bonding is not satisfying is effectively solved. The hot roll structure used for non-woven cloth production has the advantages of being rapid, reliable and convenient.

Description

A kind of hot roll structure for non-weaving cloth production

[technical field]

The utility model relates to field of textiles, the improvement of the hot roll structure of producing in particular for non-weaving cloth.

[background technology]

In the production of non-weaving cloth, all need to adopt hot roll to carry out heat bonding.

Conventional hot roll structure generally adopts the structure of top roll and lower roll, set-point type on the top roll, and lower roll is smooth, the lower roll central through hole, can form compressional deformation after passing into the deep fat supercharging, realize two gap adjustment between the roller, thereby carry out fiber is carried out heat bonding.At present, adopt crowned roll, lower slightly in the middle of the top roll in the operation process, so outline is high in the middle of the lower roll, remedies its variable, reaches the hot rolling purpose.

There is following problem in present this structure:

1, because the logical oily supercharging in the center of lower roll is not fine so produce the effect of compressional deformation, and the deformation of lower roll outer peripheral face changes smaller, hot sticky effect is relatively poor;

2, temperature was lower after the logical oil in lower roll center, the heat of oil were delivered to the outer surface of lower roll, thereby caused the heat bonding effect relatively poor, was to guarantee product quality, just needed to reduce and advance cloth speed, guaranteed the heat bonding effect, caused production efficiency to descend.

[utility model content]

The purpose of this utility model solves the problems of the prior art exactly, proposes a kind of hot roll structure for non-weaving cloth production, not only can improve the heat bonding effect, and can enhance productivity.

For achieving the above object, the utility model proposes a kind of hot roll structure for non-weaving cloth production, comprise top roll, with the lower roll of the parallel placement of top roll, the side face inboard of described lower roll is provided with the supercharging circulation canal, described supercharging circulation canal comprises the separate first half and Lower Half, the right-hand member of described Lower Half is oil-in, and the left end of Lower Half is connected to the left end of the first half, and the right-hand member of the first half is oil-out.

As preferably, also comprise valve, described valve is located at oil-in or oil-out place, controls the amount that oil is gone out by valve.

As preferably, the center of described top roll is provided with the top roll passage, improves the heat bonding effect.

As preferably, after the pressurization, the ejection amount of lower roll makes lower roll become resilient roller more than or equal to 0.5mm in the supercharging circulation canal of described lower roll, improves the heat bonding effect.

The beneficial effects of the utility model: the utility model has greatly improved structure reliability in operation process, and guaranteed the heat bonding effect, efficiently solve lower roll and eject quantity not sufficient, cause the heat bonding effect bad, and because the bad need of heat bonding effect are often adjusted cloth speed causes advances the slow-footed problem of cloth, have fast, reliably, advantage easily.

Feature of the present utility model and advantage will be elaborated by reference to the accompanying drawings by embodiment.

[description of drawings]

Fig. 1 is the structural representation of a kind of hot roll structure of producing for non-weaving cloth of the utility model.

[specific embodiment]

As shown in Figure 1, a kind of hot roll structure for non-weaving cloth production, comprise top roll 1, with the lower roll 3 of top roll 1 parallel placement, the side face inboard of described lower roll 3 is provided with supercharging circulation canal 4, described supercharging circulation canal 4 comprises the separate first half 41 and Lower Half 42, the right-hand member of described Lower Half 42 is oil-in 43, and the left end of Lower Half 42 is connected to the left end of the first half 41, and the right-hand member of the first half 41 is oil-out 44.The center of described top roll 1 is provided with top roll passage 2.

Also comprise valve 5, described valve 5 is located at oil-in 43 or oil-out 44 places.After the pressurization, the ejection amount of lower roll 3 is more than or equal to 0.5mm in the supercharging circulation canal 4 of described lower roll 3, and this lower roll 3 becomes resilient roller.Described supercharging device can adjusting oil mass, controls the amount that oil is gone out by valve 5, effectively controls the ejection amount of lower roll 3, after the pressurization ejection amount greater than 0.5mm, thereby effectively guaranteed the heat bonding effect.

Above-described embodiment is to explanation of the present utility model, is not to restriction of the present utility model, any scheme after the utility model simple transformation is all belonged to protection domain of the present utility model.
