Description

The once-combined device of two-sided leather

Technical field

The present invention relates to artificial leather field, particularly the once-combined device of a kind of two-sided leather.

Background technology

Leather is a kind of natural leather processed by mammal skin, there is pliability good, the feature that gas permeability is strong, and there is comparatively comfortable feel, corium is of a great variety, but it is expensive mostly, requires higher to storage, nursing, therefore should not popularize, and the mankind to kill animal and have also become the extinction of many animals or endangered arch-criminal in order to leather is excessive; Artificial leather is a kind of outward appearance, feel also can replace it to use like leather plasticsgoods are base usually with fabric, coating synthetic resinand various plastics interpolation is made, ordinary people's fabricate-leather low price, color is beautiful bright-coloured, numerous in variety, but its comfort level is not as corium, and gas permeability, wearability and cold resistance are also poor, are easy to senile abrasion.

Artificial leather can be divided into polyvinyl chloride, polyamide, polyurethane, polyolefin etc. according to material difference; Wherein polyvinyl chloride is current the most widely used artificial leather, and it can be divided into again single side and double-side type two kinds according to the base fabric number of plies, and single side refers to by one deck base cloth and one deck igelite gluing complex bonded to each other; Two-sided leather refers to two layers of base fabric, the complex of middle one deck polyvinyl chloride, be usually used in the liner of case and bag, current two-sided leather is commonly used rolling process and is produced, a tablecloth frame is all placed after calender, be compounded to form one side with calendering polyvinyl chloride film out remove from office for putting base fabric, one side leather again with base fabric compound, form two-sided leather, the method need through twice compound, complex procedures, and easily cause upper and lower two-layer base cloth in uneven thickness, affect end product quality, high-grade liner base cloth can not be met even, the requirement that fastness is high.

Utility model content

For the problems referred to above, provide a kind of two-sided leather once-combined device, this apparatus structure is simple, and the two-sided leather obtained is smooth, fastness is high.Improve the defect that current two-sided leather abscess is larger, the utility model is achieved in that

The once-combined device of a kind of two-sided leather, comprise four-roll calender and cloth holder, it is characterized in that, two cloth holders are positioned at calender rear end and parallel with roll shaft, upper Ji Bu and lower base cloth are located in cloth holder and lower cloth holder respectively, lower cloth is placed on below calender the 4th roller, and upper cloth is placed on above calender the 3rd roller, and upper Ji Bu and third and fourth roller gap plane (i.e. polyvinyl chloride film plane) of four-roll calender are in 45° angle.

Further, in the utility model, lower Ji Bu and third and fourth roller gap plane (i.e. polyvinyl chloride film plane) of four-roll calender are in 70 ° of-80 ° of angles.

The utility model is for double-side type water-based artificial leather (two layers of base fabric, middle compound one deck polyvinyl chloride) set composite, in the upper and lower two-layer compound base fabric object of polyvinyl chloride film while of in order to reach one time, two cloth holders are set in four-roll calender rear end, lower cloth holder is positioned at below the 4th roller, upper cloth holder is positioned at above the 3rd roller, and with third and fourth roller gap plane (i.e. polyvinyl chloride film plane) in miter angle, through repeatedly testing, if angle is excessive, can cause pasting injustice when cloth and Film laminated, pasting the situation of wrinkling; The utility model makes improvement to existing two-sided leather twice set composite, easy and simple to handle, and the two-sided leather base cloth obtained is smooth and fastness is high, meets high-grade case and bag (as high-grade PVC fabric, corium etc.) liner requirement.

Accompanying drawing explanation

Fig. 1 is embodiment of the present invention structural representation;

In figure, 1, upper cloth holder; 2, lower cloth holder; 3, third and fourth roller gap plane of calender; 4, upper base cloth; 5, lower base cloth; 6, a roller; 7, two rollers; 8, three rollers; 9, four rollers.

Detailed description of the invention

Embodiment 1

As shown in Figure 1, the once-combined device of a kind of two-sided leather, comprise four-roll calender and cloth holder, two cloth holders are placed in four-roll calender rear end, above four-roll calender the 3rd roller 8, steel platform is set, cloth holder 1 placed by steel platform, oil pump and school deflection device is installed simultaneously, make cloth holder 1 can automatic correcting; Lower cloth holder 2 is placed in below four-roll calender the 4th roller 9, upper cloth holder 1 is all parallel with calender roll shaft with lower cloth holder 2, upper base cloth 4 is positioned at cloth holder 1, lower base cloth 5 is positioned at lower cloth holder 2, and upper base cloth 4 and third and fourth roller of four-roll calender (8,9) gap plane 3(and polyvinyl chloride film plane) in 45° angle.

In the present embodiment, lower base cloth 5 and third and fourth roller of four-roll calender (8,9) gap plane 3 are in 75 ° of angles, and in specific operation process, lower base portion and this Plane Angle scope can be 70 °-80 °.

In specific operation process, upper base cloth 4 is high tenacity polyester fiber yarn with lower base cloth 5, then with the polyvinyl chloride film compound that extrudes in four-roll calender, namely with upper and lower two-layer Polyester Yarns compound while of when film pulls out, in Fig. 1, the direction of arrow is the polyvinyl chloride film direction of motion, through cooling wheel rolling after cooling, namely obtain two-sided leather.

The two-sided leather base cloth obtained by this once-combined device is smooth and fastness is high, meets high-grade case and bag (as high-grade PVC fabric, corium etc.) liner requirement.
