Abstract

The utility model relates to a cotton gin leather roller adhesive tape. The utility model adopts the technical scheme that the cotton gin leather roller adhesive tape is formed by clipping a rubber sisal plate which comprises sisal netting cloth, and a rubber layer is coated on the sisal netting cloth; the sisal netting cloth is covered on the rubber layer, and the sisal netting cloth and the rubber layer are vulcanized into whole after being spaced and stacked. Because the cotton gin leather roller adhesive tape adopts the sisal netting cloth as base material, and the high roughness concentration and the staying quality of the sisal and white rubber combine perfectly, the implement of the technical scheme greatly improves the friction coefficient of the roll surface of the leather roller and the traction force of the roll surface for cotton fibre, thereby the effect of doffing is greatly improved. The machining technology of the cotton gin leather roller adhesive tape is easy to operate and realize and is convenient to product and implement.

Description

Gin roller rubber strip

technical field

The utility model relates to an accessory for a cotton gin, in particular to a leather roller rubber strip for a cotton gin.

Background technique

Cotton gin rollers are key components of the cotton gin, and their quality directly affects the quality of the processed cotton. At present, the most widely used is the black top roller. The black top roller is generally made of rubber strips cut from waste automobile tires and fixed on the roller surface. The carbon black in the black rubber pollutes the cotton. In addition, the cord layer in the tire rubber strips Contains chemical fibers, which can contaminate cotton and reduce the quality grade of cotton.

There is also a kind of white leather roller imported from abroad, which is composed of canvas discs with holes in the center to form a ferrule. The end cap is pressed tight. This white top roller is made of pure cotton canvas, bonded with white rubber, and vulcanized. Cotton gins can improve the quality grade of cotton by using the white roller, and prevent pollution to cotton. However, the friction coefficient of the roller surface of this white top roller is low, and the traction force on cotton fibers is small.

Utility model content

The utility model aims at the disadvantages of the prior art, and provides a technical scheme of a white top roller with a high roller surface friction coefficient, a large traction force on cotton fibers and a long service life.

The utility model is realized through the following technical measures: it is cut from a plastic hemp board, and the rubber hemp board includes a hemp mesh cloth, the hemp mesh cloth is coated with a rubber layer, and the rubber layer is covered with a hemp mesh cloth, The hemp mesh cloth and the rubber layer are vulcanized as a whole after the upper and lower intervals are stacked and arranged in this way. Among them, the hemp mesh cloth can be selected to be woven with warp and weft hemp threads with a thickness of 0.8-2 mm to form a grid mesh.

The mesh of the above-mentioned hemp mesh cloth should not be too large, generally in the range of 0.8mm×0.8mm to 1.2mm×1.2mm, and a grid mesh of 1×1mm is used specifically for the best effect.

The working surface of the above-mentioned rubber strip is the side of the glue linen board, and the side is at an angle of 45 degrees with the warp or weft of the linen mesh. This can ensure the durability of the rubber strip working surface under the premise of increasing the traction force on the cotton thread. Abrasiveness and prolonging its service life, its elongation at break can reach 500%, and its breaking strength can reach 13MPa.

The above-mentioned glue linen board is made in the following way: take the linen mesh cloth, calender the EPDM rubber to make the linen mesh cloth glued to 0.5kg/m ² , and the linen mesh cloth after glued is along the After the warp or weft of the mesh is cut into a number of isosceles right-angled triangles at an angle of 45 degrees, four arranged triangles are arranged to form a square, and the long hypotenuses of the four triangles form the sides of the square, and then several layers are superimposed to form a certain thickness. After forming With a unit pressure of not less than 2.5MPa, vulcanize at a temperature of 150-155°C to form a glue-lined board.

The above-mentioned rubber can be EPDM rubber, which can be purchased directly.

The beneficial effect of this scheme can be known according to the description of the above scheme. Because it uses hemp mesh as the base material, the high roughness and wear resistance of hemp and the perfect combination of white rubber, the implementation of the technical scheme can greatly improve the The friction coefficient of the roller surface of the top roller and the traction force of the cotton fiber on the roller surface are improved, therefore, the doffing effect is greatly improved.

Detailed ways

In order to clearly illustrate the technical features of the solution, the solution will be described below through a specific implementation mode combined with the accompanying drawings.

A kind of gin rubber strip, as shown in Fig. 1 and Fig. 2, it is cut from the hemp board, and the hemp board includes the hemp mesh cloth 2, and the hemp mesh cloth 2 is coated with a rubber layer 1, The rubber layer 1 is covered with a hemp cloth 2, and the hemp cloth 2 and the rubber layer 1 are stacked and arranged at intervals in this way, and vulcanized as a whole. The hemp mesh 2 is made of warp and weft hemp threads with a thickness of 0.8-1.2 mm to form a grid, and the mesh of the hemp mesh 2 is 1×1 mm. The working surface 3 of the glue strip is the side of the glue linen board, and the warp or weft of the side and the linen mesh 2 is at an angle of 45 degrees. Among them, the glued linen board is made in the following way: take the linen mesh 2, and calender the rubber to make the linen mesh glued to 0.5kg/m ² , and the linen mesh 2 after glueing is along the warp line of the linen mesh. Or after the latitude is cut into several isosceles right triangles at an angle of 45 degrees, the four isosceles right triangles are arranged into a square, and the long hypotenuses of the four triangles form the sides of the square, and then 12 layers are superimposed to form a certain thickness. The unit pressure is not lower than 2.5MPa, and vulcanized at a temperature of 150 to 155°C to form a rubber hemp board.
