Abstract
The utility model discloses a measuring instrument for degree of curling of canvas. A clamp holder is fixed at one end of a fixing plate, and a steering wheel is arranged at the other end of the fixing plate; and one end of detected yarn is fixed by the clamp holder, and the other end of the detected yarn is fixed with a weight and naturally falls through the steering wheel. The measuring instrument can accurately measure the degree of curling of the canvas in a standard way, and is convenient to use, and the input cost of equipment is low.
Description
Technical field
The utility model relates to surveying instrument, in particular, relates to a kind of canvas crimpness surveying instrument.
Background technology
At present, domestic layering conveying belt manufacturer more and more payes attention to for canvas crimpness index.The choose reasonable of canvas crimpness is conducive to improve the anti-performance that circumnutates of conveying belt, reduces cross-section crackle and horizontal delamination.
Referring to Fig. 2 as can be known, crimpness=(L1-L0)/L1 all is to make by hand that yarn is stretchingly to each company of measurement of crimpness at present, and yarn is long before and after measuring, and then calculates crimpness.This method has larger difference because of the difference of survey crew, the degree of accuracy that impact is measured.
The utility model content
Technical problem to be solved in the utility model is to realize a kind of instrument that can measure the canvas crimpness accurately.
To achieve these goals, the technical solution adopted in the utility model is: a kind of canvas crimpness surveying instrument, and fixed head one end is fixed with clamper, and the other end is provided with deflecting roller, detected yarn one end is fixed by clamper, and the other end is counterweight and naturally droop by deflecting roller fixedly.
Fixed head between described clamper and the deflecting roller is provided with scale.
Be provided with the pointer chute along described scale, being provided with in the described pointer chute can be along the pointer of its slip.
Described clamper comprises the back-up block that is fixed on the fixed head, cooperates the clamping plate of back-up block clamping yarn, and the tie down screw that connects back-up block and clamping plate.
The utility model has the advantage of this surveying instrument can be accurately, standard the canvas crimpness is measured, easy to use, the equipment investment cost is low.
Description of drawings
The below makes brief description to the content of every width of cloth accompanying drawing expression in the utility model instructions and the mark among the figure:
Fig. 1 is canvas crimpness surveying instrument structural representation;
Fig. 2 is the crimpness instrumentation plan;
Mark among the above-mentioned figure is: 1, clamper; 2, deflecting roller; 3, counterweight; 4, pointer; 5, scale; L1: length of yarn; L0: cloth length.
Embodiment
Referring to Fig. 1 as can be known, canvas crimpness surveying instrument comprises fixed head, clamper 1, deflecting roller 2, counterweight 3, pointer 4 and scale 5.Wherein fixed head is instrument base, clamper 1 is fixed in fixed head one end, in order to fixing tested yarn end, clamper 1 comprises the back-up block that is fixed on the fixed head, the clamping plate that cooperate back-up block clamping yarn, and the tie down screw that connects back-up block and clamping plate, can carry out gripping and fixing operation to yarn by unscrewing or screw fastening screw.Deflecting roller 2 is tested yarn support member, and it is fixed on the fixed head other end by wheel carrier, and wheel carrier stretches out the fixed head edge obliquely with deflecting roller 2, makes things convenient for the yarn bending sagging.
In order to be convenient for measuring the stretching length of tested yarn, fixed head between clamper 1 and deflecting roller 2 is provided with scale 5, and be provided with the pointer chute along this scale 5, being provided with in the pointer chute can be along the pointer 4 of its slip, and sliding pointer 4 can make things convenient for, measure accurately the length of the yarn that is straightened like this.
When carrying out the crimpness measurement, first yarn one end is fixed in the clamper 1, the other end is counterweight 3 fixedly, and naturally droop by deflecting roller 2, because counterweight 3 is rated weight, therefore the dynamics of each stretching yarn is identical, the error of manual backguy can not occur, utilizes afterwards scale 5 and pointer 4 to carry out linear measure longimetry and can calculate the canvas crimpness.
The above has carried out exemplary description to the present invention by reference to the accompanying drawings; obviously the utility model specific implementation is not subjected to the restriction of aforesaid way; as long as adopted the improvement of the various unsubstantialities that method of the present invention design and technical scheme carry out; or without improving design of the present invention and technical scheme are directly applied to other occasion, all within protection domain of the present utility model.
