[ Detailed description ] of the invention
The utility model will be described in detail below with reference to the drawings and the detailed description.
The utility model provides a cap ply longitudinal cutting slitting machine with a cap ply adhesion reducing function, which is shown in figure 1 and comprises a cap ply longitudinal cutting slitting machine, wherein the cap ply longitudinal cutting slitting machine comprises a traction roller 5 and a curtain cloth dividing device 6, the traction roller 5 is used for guiding a wide cap ply 7 led out by a cap ply coil 4 to the curtain cloth dividing device 6, and the curtain cloth dividing device 6 is used for dividing the wide cap ply 7 into a plurality of cap ply strips 8; one or two crown strap tack reducing means are provided at the location of the wide crown strap 7 between the crown strap roll 4 and the pull roll 5, i.e. a means for reducing crown strap tack is added to the pull path of the pull roll 5 before the wide crown strap enters the curtain-dividing means 6. It is also possible to provide a plurality of crown strap tack reducing means depending on the length of the wide crown strap 7 or the need to reduce the tack.
As shown in fig. 2, each of the crown strap tack reducing devices specifically includes:
The base 1 is of a plate structure, the base 1 is fixedly arranged below the wide crown strap 7, and as shown in fig. 3, a plurality of steel needles 3 are vertically arranged on the upper surface of the base 1 upwards. The cover plate 2 is of a plate structure, the cover plate 2 and the base 1 are symmetrically arranged and are located above the wide crown strap 7, and as shown in fig. 3, a plurality of steel needles 3 are vertically arranged on the lower surface of the cover plate 2 downwards. The steel needles 3 on the base 1 and the steel needles 3 on the cover plate 2 are arranged according to the length of not less than 240mm and the width of not less than 50 mm; the spacing between the free end of the steel needle 3 of the cover plate 2 and the free end of the steel needle 3 on the base 1 is 0.65-0.83mm.
Each crown strap tack reducing device further includes two ball screw mechanisms, the screw 10 of each ball screw mechanism being disposed vertically and on both sides of the base 1, respectively, and the slider 11 of each ball screw mechanism being detachably connected to both sides of the cover plate 2, respectively. Each slider 11 is configured to move up and down along the screw 10, thereby driving the cover plate 2 to move up and down relative to the base 1, so as to adjust the distance between the cover plate 2 and the base 1. Each steel needle 3 is used to scrape the upper and lower surfaces of the wide crown band 7 during the movement of the wide crown band 7 to reduce the tackiness of the wide crown band 7.
The thickness of the wide crown band 7 is 0.84mm, and the width is divided into 160mm and 240mm. The wide crown band 7 is divided into an inner layer structure and an outer layer structure, nylon cords with the thickness of 0.6mm are arranged in the wide crown band, and sizing materials with the thickness of 0.12mm are respectively wrapped on the upper portion and the lower portion of the nylon cords. By using the cap ply longitudinal cutting slitting machine with the function of reducing the adhesiveness of the cap ply, the spacing between the cover plate 2 and the base 1 is adjusted, so that the spacing between the upper layer and the lower layer of steel needles 3 is within the interval of 0.65-0.83mm, and the situation that the adhesive material layer of the wide cap ply 7 is scraped can be ensured without damaging nylon cords. When the viscosity of the wide crown band 7 is larger, the distance between the steel needles 3 on the upper layer and the lower layer is reduced as little as possible, and a plurality of adhesive layers are scraped off, so that the viscosity can be reduced better; otherwise, the distance between the upper and lower steel needles 3 can be increased by a little.
In some embodiments, when a crown strap tackiness reducing device is provided, the arrangement density of the steel needles 3 on the cover plate 2 and the base 1 is 16-32 steel needles/cm 2, and the length of each steel needle 3 is 20mm.

For example, the use of two crown strap tack reducing devices is selected according to four conditions of tack from low to high: ① When the wide crown band is less tacky, both crown band tack reducing devices may not be activated; ② When the wide crown band has a slightly higher viscosity, only one crown band viscosity reducing device with lower steel needle density can be started; ③ When the wide crown band has higher viscosity, only one crown band viscosity reducing device with higher steel needle density can be started; ④ When the viscosity of the wide crown band is high, two crown band viscosity reducing devices can be started at the same time, steel needles of the two crown band viscosity reducing devices can be arranged in staggered arrangement, and the scratch density of the steel needles on the wide crown band can be increased when the wide crown band is used. The specific progressive standard of the viscosity is selected according to the actual working condition.
In some embodiments, the density of steel needles 3 of the crown strap tack reducing device adjacent to crown strap coil 4 is 12-16 per cm 2 and the density of steel needles 3 of the other crown strap tack reducing device is 24-32 per cm 2.
In some embodiments, as shown in fig. 2, the motors 9 of the two ball screw mechanisms are connected by a cross beam 12.
The utility model relates to a cap ply longitudinal cutting and slitting machine with a cap ply tackiness reducing function, which comprises the following working processes:
The wide crown band 7 led out by the crown band roll 4 is led to the curtain cloth dividing device 6 by the traction roller 5, and the curtain cloth dividing device 6 can divide the wide crown band 7 into a plurality of crown bands 8;
When the surface viscosity of the wide crown band is large, the distance between the cover plate 2 and the base 1 is adjusted, namely the distance between the upper layer of steel needles 3 and the lower layer of steel needles 3 is adjusted to be within the interval of 0.65-0.83mm, and the traction roller 5 pulls the wide crown band 7 to pass through the space between the upper layer of steel needles 3, so that the steel needles 3 are contacted with the rubber material surface of the wide crown band 7, the smoothness of the rubber material layer surface is damaged, the roughness between the curled crown band 7 is increased, the contact area between the layers of the segmented crown band 8 is reduced, and the viscosity between the layers of the crown band 8 is reduced;
If it is not necessary to reduce the tackiness of the wide crown, the cover plate 2 and the base 1 may be separated so that the steel needle 3 does not come into contact with the rubber surface of the wide crown 7.
Because of the fluctuation of raw materials, the difference of the viscosity of the crown belt materials can occur, if the viscosity is too large, the cut crown belt strips are adhered when wound again, some of the crown belt strips can be adhered and scrapped, and the quality defect of nylon cord exposure can occur, so that the excessive viscosity of the wide crown belt can greatly influence the next process. According to the utility model, a cap ply longitudinal cutting slitting machine with a function of reducing the tackiness of the cap ply is adopted, and the adhesive on the surface of the cap ply is scraped to form a plurality of scratches, namely concave long grooves are formed on the surface of the cap ply at a microscopic angle, so that the contact area of the cap ply after winding is reduced, and the tackiness of the cap ply is reduced; the aim of reducing interlayer adhesive force of the curled crown strap is achieved by adjusting the parting flow of the crown strap, the quality problem that the crown strap is deglued and whitened due to overlarge adhesive is solved, the problem that a large amount of materials are wasted due to overlarge adhesive and incapability of being normally guided open during molding is solved, the problem that the quality of the tire is reduced due to the deficiency of a cord is solved, and the production cost of the tire is reduced.
