Embodiment one
Below in conjunction with accompanying drawing, test process is described.
{ qualified powder cylinder test }
Before starting test, carbon dust cavity volume 132 need be pulled out, claim its weight to be m1, then be inserted in testing apparatus 1 along x direction in Fig. 3 by carbon dust cavity volume 132, then rotating cycle setting knob 111, to set the rotating cycle n1 of driven wheel 123.Fig. 6 is the A-A face cut-open view of powder cylinder testing apparatus in the embodiment of the present invention, and as shown in Figure 6, qualified powder cylinder 21 is placed in powder cylinder cavity volume 121, and the driving force of qualified powder cylinder 21 receives gear 60 and engages with connecting rod 15; The toner supply port 25 of qualified powder cylinder 21 and carbon dust outlet 32 overlap under the effect of described push rod 7.Now, operator presses start key 112, drive motor 122 is started working and is driven connected driven wheel 123 to rotate, simultaneously, the connecting rod 15 engaged is kept also to start to rotate with driven wheel 123, further, connecting rod 15 drives the driving force of powder cylinder reception gear 60 to rotate, carbon dust agitating device 61 in qualified powder cylinder 21 stirs the carbon dust T in qualified powder cylinder 21 under the drive of driving force reception gear 60, and make described carbon dust T send into carbon dust outlet 32 by carbon dust conveying screw rod 50, because carbon dust outlet 32 now and toner supply port 25 overlap, therefore, carbon dust T flows out from toner supply port 25 and arrives carbon dust cavity volume 132, when the rotating cycle of driven wheel 123 reaches setting value, testing apparatus 1 quits work automatically, then carbon dust cavity volume 132 is taken out, its weight is again claimed to be m2, by calculating formula M=m2-m1, namely by analog-driven gear 123 setting rotation number of turns n1 in, calculate the carbon dust amount M that qualified powder cylinder 21 consumes.
For making measurement data more accurate, can in same testing apparatus 1, and the rotating cycle of driven wheel 123 is when being also set as identical, tests out the data of the carbon dust amount that multiple qualified powder cylinder consumes respectively, and then get minimum M 1 and the maximal value M2 of these data.
In fact, the above-mentioned number of turns setting knob 111 for setting powder cylinder rotating cycle can also be the time setting knob for setting powder cylinder rotational time.
{ test of powder cylinder }
According to the test result of above-mentioned qualified powder cylinder, can produce the standard of the carbon dust supply of the powder cylinder meeting request for utilization, the carbon dust supply of powder cylinder must in the scope of minimum M 1 and maximal value M2.The method of testing of the carbon dust supply of powder cylinder can adopt the method for testing of the carbon dust consumption of above-mentioned qualified powder cylinder 21.
The carbon dust supply of powder cylinder that now hypothesis adopts above-mentioned method of testing to draw is M
0if there is relational expression: M1≤M
0≤ M2, so powder cylinder meets request for utilization; If there is relational expression: M
0<M1 or M
0>M2, so powder cylinder does not just meet request for utilization.
Embodiment two
As the preferred embodiment of above-described embodiment, the testing apparatus described in the present embodiment and above-described embodiment have roughly the same structure, and therefore, the parts that the testing apparatus of the present embodiment is identical with the testing apparatus of above-described embodiment use identical numbering.
The testing apparatus 1 of the present embodiment also comprises and to be arranged on bottom carbon dust cavity volume 132 and detected data can be carried out storing and the memory storage (not shown) of computing for the pick-up unit 14 that automatically detects carbon dust cavity volume 132 weight and the inside that is arranged on testing apparatus 1, also comprises being arranged on described control gear 11 and for representing whether powder cylinder meets the pilot lamp 113 of request for utilization.
According to the method for testing in above-described embodiment, testing apparatus 1 in the present embodiment is owing to having pick-up unit 14, memory storage and pilot lamp 113, in above-described embodiment, carbon dust cavity volume 132 is taken out the step of weighing to be replaced by described pick-up unit 14, the step calculating carbon dust consumption is replaced by described memory storage, and last weight is replaced by described pilot lamp 113 step whether when powder cylinder meets request for utilization.When powder cylinder meets request for utilization, pilot lamp 113 does not work; On the contrary, when powder cylinder does not meet request for utilization, pilot lamp 113 is shinny to point out operator.Therefore, the testing apparatus 1 in the present embodiment also can complete each testing procedure in above-described embodiment accurately.
Use the method for testing of above-mentioned powder cylinder testing apparatus, comprise the following steps:
One, after powder cylinder being put into testing apparatus, start testing apparatus, collect the carbon dust that flows out from toner supply port and measure the weight of described carbon dust;
The weight of the carbon dust two, flowed out under certain operating condition according to powder cylinder in above-mentioned testing apparatus judges that whether powder cylinder is qualified.
The operating condition of described powder cylinder is the running number of turns or the duration of runs.
Described step 2 judges that the method whether powder cylinder qualified is: when the weight of carbon dust flowed out be more than or equal to the minimum weight of qualified powder cylinder consumption under the equal operating condition of same testing apparatus and the maximum weight of qualified powder cylinder consumption under being less than or equal to the equal operating condition of same testing apparatus time be judged to be qualified, otherwise be judged to be defective.
Described step 2 is further comprising the steps of: measure the minimum weight and maximum weight that can judge the qualified powder cylinder consumption whether powder cylinder is qualified.
The minimum weight of described qualified powder cylinder consumption be multiple qualified powder cylinder is operated under the equal operating condition of same testing apparatus measured by minimal consumption weight, described maximum qualified weight be multiple qualified powder cylinder is operated under the equal operating condition of same testing apparatus measured by maximum consumption weight.
Powder cylinder cavity volume 121 in the present invention can have multiple or one, and correspondingly, described start key 112 and described carbon dust cavity volume 132 also can have multiple or one.When described powder cylinder cavity volume 121, start key 112 and carbon dust cavity volume 132 are multiple, described motor 122 can have multiple or one, driven wheel 123 and the described powder cylinder driving force of described motor receive engaging except completing by above-mentioned connecting rod 15 between gear 60, and the two also can directly engage.
Should be understood that, for the person of ordinary skill of the art, whether the testing apparatus that the present invention relates to is not limited to test powder cylinder involved in the present invention qualified, without departing from the inventive concept of the premise, have control gear, powder wound packages fitting mechanism, driving mechanism and carbon dust collecting mechanism testing apparatus can also test pack whether contain the powder cylinder of driving force receiving mechanism, carbon dust conveying mechanism and toner supply port qualified.
