Abstract
The invention relates to a production facility and process for a super-low tensibility poly V-belt cord. A stretching device is arranged in a drying oven, and the stretching device is characterized in that a stretching wheel group is formed by two groups of stretching wheels in left and right or front and back arrangement; each stretching wheel group is composed of 10-25 stretching wheels left and right or front and back arranged in two rows; a tensioner controlling the tension of the cord among the stretching wheels is arranged between the stretching wheel groups; the front part of one stretching wheel group is provided with a paying off wheel or a winding up wheel; the rear part of the other stretching wheel group is provided with a paying off wheel or a winding up wheel; and the winding up wheels provide power for driving the stretching wheels, the paying off wheels and the winding up wheels to rotate. The process comprises the following concrete steps: 1) preparation; 2) heating; and 3) stretching. In the invention, the measures such as forced stretching, re-stretching and the like are carried out on the cord, so that the stretching ratio is greatly reduced and the cord can be contracted after being heated at a certain temperature; and the elongation at break of the manufactured poly V-belt is controlled to be below 7% and the manufactured poly V-belt can be used for sixty thousand miles.
Description
Technical field:
The invention belongs to the driving belt technical field, refer in particular to a kind of ultralow production equipment and production technology thereof of stretching the polywedge bet cotton rope.
Background technology:
At present, the edge V tape framework material of producing both at home and abroad all adopts polyester cord.The percentage elongation of general polyester cord is about 8%-11%.Edge V tape uses on automobile, is defined in 20,000 kilometers with interior not roll adjustment.Because the wearing and tearing of edge V tape wedge surface after use and the elongation of framework material, after ten thousand kilometers of the uses to two, difference in addition be less than 20,000 kilometers and skid with regard to the elongation that causes edge V tape, do not extend and expensive aramid fiber even use, also the wear reason because of belt body needs roll adjustment, increase use cost, used inconvenience.
Summary of the invention:
The purpose of this invention is to provide a kind of ultralow production technology of stretching polywedge bet that makes polywedge bet remain tense situation.
The present invention is achieved in that
The ultralow production equipment of stretching the polywedge bet cotton rope, in baking oven, be provided with stretching device, described stretching device is: arranged by about two groups of stretching wheels or front and back and form the stretching wheels, each stretching wheels is made up of the stretching wheels that about 10-25 or front and back become two rows to be provided with, at the Tension Control instrument that is provided with the tension force of cotton rope between the control stretching wheel between the stretching wheels, be provided with actinobacillus wheel or take-up pulley in the front portion of one group of stretching wheels, the rear portion of another group stretching wheels is provided with take-up pulley or actinobacillus wheel, and take-up pulley is provided with the driving stretching wheel, the power that actinobacillus wheel and take-up pulley rotate.
Ultralow production technology of stretching the polywedge bet cotton rope, concrete steps are as follows:
1) prepares: be fixed on the take-up pulley after rising polyester cord on the stretching wheel that is sleeved on successively on the stretching wheels by actinobacillus wheel;
2) heating: the temperature in the heating box is elevated to certain temperature, polyester cord is softened at a certain temperature;
3) stretch: start power, drive stretching wheel, actinobacillus wheel and take-up pulley and rotate, cotton rope is through behind actinobacillus wheel, stretching wheel and the take-up pulley, because the effect of tension force, cotton rope is drawn into elongation at break≤7%, and ultralow to stretch cotton rope standby.
The linear velocity of above-mentioned cotton rope is 10-20 rice/5 minute.
Above-mentioned certain temperature is 80-100 ℃.
The outstanding compared to existing technology advantage of the present invention is:
1, the present invention measure such as takes to force that stretching is extended again to the polyester cord of edge V tape on technology, make it to reach and greatly reduce the effect of under the back uniform temperature of being heated, shrinking in percentage elongation and the use, remedied because of the belt body wearing and tearing narrow down and caused the defective of belt body elongation, made polywedge bet remain tense situation;
2, the elongation at break of the polywedge bet of the present invention's production is controlled at below 7%;
3, the polywedge bet produced of the present invention is using to 60,000 kilometers, can be because of elongation roll adjustment, easy to use, use cost is low;
4, the polywedge bet of the present invention's production is applicable to the machine driving on the automobile.
Description of drawings:
Fig. 1 is the structural representation of tensioning system of the present invention.
The specific embodiment:
With specific embodiment the present invention is further described below, referring to Fig. 1:
The ultralow production equipment of stretching the polywedge bet cotton rope, in baking oven 10, be provided with stretching device, described stretching device is: arranged by two groups of stretching wheels about 40 or front and back and form the stretching wheels, each stretching wheels is made up of the stretching wheels 40 that about 10-25 or front and back become two rows to be provided with, at the Tension Control instrument that is provided with the tension force of cotton rope 30 between the control stretching wheel between the stretching wheels, be provided with actinobacillus wheel 50 or take-up pulley 20 in the front portion of one group of stretching wheels, the rear portion of another group stretching wheels is provided with take-up pulley 20 or actinobacillus wheel 50, and take-up pulley 20 is provided with the driving stretching wheel, the power that actinobacillus wheel 50 and take-up pulley 20 rotate.
Ultralow production technology of stretching the polywedge bet cotton rope, concrete steps are as follows:
1) prepares: be fixed on the take-up pulley after rising polyester cord on the stretching wheel that is sleeved on successively on the stretching wheels by actinobacillus wheel;
2) heating: the temperature in the heating box is elevated to certain temperature, polyester cord is softened at a certain temperature;
3) stretch: start power, drive stretching wheel, actinobacillus wheel and take-up pulley and rotate, cotton rope is through behind actinobacillus wheel, stretching wheel and the take-up pulley, because the effect of tension force, cotton rope is drawn into elongation at break≤7%, and ultralow to stretch cotton rope standby.
The linear velocity of above-mentioned cotton rope is 10-20 rice/5 minute.
Above-mentioned certain temperature is 80-100 ℃.
Use the technology of the cotton rope production polywedge bet of the said equipment and explained hereafter can be:
Blank → white silk glue → go out piece → with cotton rope moulding → sulfuration together → cut → polish → the polywedge bet finished product according to certain standard.
The polywedge bet that cotton rope of the present invention is produced in use can thereby not shrink because of the former of temperature, simultaneously, also avoided because of the wearing and tearing of belt body in use, caused internal tooth on the belt body to fall in the corresponding groove that is provided with it and carry out the defective of roll adjustment because of elongation.
The foregoing description is one of preferred embodiment of the present invention only, is not to limit practical range of the present invention with this, so: all equivalences of doing according to shape of the present invention, structure, principle change, and all should be covered by within protection scope of the present invention.
