Wherein 1# and 2# tension station, and constitute separately between the tensile region between 2# and the 3# tension station are bathed and Tension Control is carried out in the two-bath gum dipping interval one.
This structure arranges that existing problems are: if adopt high-tension impregnation, the then stressed increase of yarn; The cohesive force of fiber is just high, and dipping solution can't permeate, even adopt high extruding force; Also can't solve infiltration problem well, easy starved forms the space in the middle of the fiber.If adopt the low-tension impregnation, increase extruding force subsequently, then can solve infiltration problem; But in dry run subsequently; Because the evaporation of internal moisture, volume reduces, and inner core must absorb the dipping solution of superficies; Cause the reduction of appearance impregnation coverage rate, finally cause the reduction of bonding strength; If strengthened infiltration capacity, then often also be that the inner core rubber absorption capacity increases, cause drying, heat treatment after, rubber shoe latex layer occurs in the table widely different.
Summary of the invention
The utility model technical problem to be solved is: the structure at the impregnation station of a kind of cord fabric and canvas cement dipping machine is provided, can't solves infiltration problem well with what solve that present cement dipping machine exists, starved easily in the middle of the fiber forms the space; Perhaps inner core absorbs the dipping solution of superficies, causes the reduction of appearance impregnation coverage rate, finally causes reduction or the like the deficiency of bonding strength.
The technical scheme of the utility model is: it comprises with lower device: be followed successively by impregnation forward pull station, tension force measuring roll, steeping vat, pressurizing unit and impregnation tension station, vacuum suction adhesive dispenser, baking oven, impregnation backward pull station according to the gum dipping process flow process.
In the course of work, connect successively by impregnation product (cord fabric is or/and canvas) between each device.
Impregnation forward pull station is the draw groups of being made up of 5-7 cylinder, and this draw groups is dragged by frequency converter.
Pressurizing unit and impregnation tension station are the draw groups of being made up of 3-5 cylinder, and this draw groups is dragged by frequency converter.
Impregnation backward pull station is the draw groups of being made up of 5-7 cylinder, and this draw groups is dragged by frequency converter.
Between impregnation forward pull station and pressurizing unit and impregnation tension station, pressurizing unit and impregnation tension station and impregnation backward pull station, a tension force measuring roll is installed separately.
Above technical scheme is according to the gum dipping process flow process structure of the impregnation tension station of cement dipping machine to be explained.
Wherein impregnation forward pull station and impregnation tension station, and constitute separately between the tensile region between impregnation tension station and the impregnation backward pull station, to carrying out Tension Control between impregnation interval and dry section.
The actual tension that speed controlling can be responded to through the tension force measuring roll with set warp tension ratio to after, realize regulating automatically.Perhaps directly set between impregnation forward pull station and the impregnation tension station and impregnation tension station and impregnation backward pull station between hauling speed, the fixed traction speed ratio.
In the immersing glue process, the tension force of can lower as far as possible impregnation forward pull station and impregnation tension station, the fiber in the fabric is in fluffy state like this; Help in the immersing glue process; Being penetrated in the fabric inner core of latex particle with the high-tension extruding, further strengthened the infiltration of latex subsequently; Inhale adhesive dispenser through vacuum again, the dipping solution that remains in the surface after the extruding is absorbed; Get into drying oven subsequently, improve the tension force at impregnation tension station and impregnation backward pull station, adopt high-tension dry; The cohesive force of fiber improves like this, and the latex in the fabric inner core is under heavily stressed squeezing action between the fiber, and the latex that part is unnecessary is expressed to fabric face; Even inner core dipping solution oven dry; Smaller volume, but under the effect of fibre cohesion, distance also diminishes thereupon between the fiber.Can not occur the appearance dipping solution is adsorbed onto in the inner core and go.
The utility model and prior art have relatively improved the penetrating power of dipping solution to cord fabric and canvas, thereby have improved product quality, make cord fabric, canvas behind the impregnation reach desirable impregnation state.
