A kind of filtration paper web lacks paper detecting apparatus
Technical field
The present invention relates to a kind of filtration paper web and lack paper detecting apparatus.
Background technology
The paper tape filter has been widely used in industrial every field; Paper tape is the main consumptive material of this machine; General machine all has the function of automatic paper feed; But when filter paper is about to use up; The filtration paper cylinder that must artificial more renew gets on; If in time not finding filter paper uses up; Will cause filter inefficacy, board to shut down and influence production so; All discharge the back filter up to old filter paper and could recover normally, reinstall filter paper and need spend more time cost and cost of labor thereby make.
Summary of the invention
The purpose of this invention is to provide a kind of filtration paper web and lack paper detecting apparatus, simple in structure, realize filtering paper web and lack the automation that paper detects, save labour turnover and time cost, avoid shutting down influence and produce, overcome the deficiency of above-mentioned aspect in the existing product.
The objective of the invention is to realize through following technical scheme:
A kind of filtration paper web lacks paper detecting apparatus; Comprise mount pad, sensor, pilot bar and measuring jaw; Said mount pad is fixed on a side of filtration paper cylinder support; Filtration paper cylinder is positioned at the opposite side of filtration paper cylinder support; The mount pad lower end is provided with linear bearing; Be provided with pilot bar in the linear bearing; The pilot bar lower end is provided with block; Be with spring on the pilot bar between block and the mount pad; The pilot bar upper end is provided with target plate; The upper end, right side of target plate is provided with two measuring jaws, and the right-hand member of measuring jaw is provided with roller, and roller and filtration paper cylinder are tangent; The mount pad upper end is provided with guide plate, and guide plate is provided with sensor.
Beneficial effect of the present invention is: simple in structure, and realize filtering paper web and lack the automation that paper detects, save labour turnover and time cost, avoid shutting down influence and produce.
Description of drawings
With reference to the accompanying drawings the present invention is done further explain below.
Fig. 1 is the described a kind of structural representation that paper web lacks paper detecting apparatus that filters of the embodiment of the invention;
Fig. 2 is the described a kind of state reference map when filtering paper web and lacking paper detecting apparatus and change filtration paper cylinder of the embodiment of the invention.
Among the figure:
1, mount pad; 2, filtration paper cylinder; 3, filtration paper cylinder support; 4, linear bearing; 5, pilot bar; 6, block; 7, spring; 8, target plate; 9, measuring jaw; 10, roller; 11, guide plate; 12, sensor.
The specific embodiment
Shown in Fig. 1-2; The described a kind of filtration paper web of the embodiment of the invention lacks paper detecting apparatus; Comprise mount pad 1; Sensor 12; Pilot bar 5 and measuring jaw 9; Said mount pad 1 is through being bolted to a side of filtration paper cylinder support 3; Filtration paper cylinder 2 is positioned at the opposite side of filtration paper cylinder support 3; Mount pad 1 lower end is provided with linear bearing 4; Be provided with pilot bar 5 in the linear bearing 4; Pilot bar 5 lower ends are provided with block 6; Be with spring 7 on the pilot bar 5 between block 6 and the mount pad 1, pilot bar 5 upper ends are provided with target plate 8, and the upper end, right side of target plate 8 is provided with two measuring jaws 9; The right-hand member of measuring jaw 9 is provided with roller 10, and roller 10 is tangent with filtration paper cylinder 2; Mount pad 1 upper end is provided with guide plate 11, and guide plate 11 is provided with sensor 12.
During use, pilot bar 5 is under spring 7 effects, and roller 10 remains with filtration paper cylinder 2 tangent, the driven rotation of meeting when roller 10 rotates at filtration paper cylinder 2, thus reduced the friction force between filtration paper cylinder 2 and the measuring jaw 9, it is smooth and easy to guarantee that filtration paper cylinder 2 rotates.Consumption along with filter paper on the filtration paper cylinder 2; Filtration paper cylinder 2 diameters constantly reduce; Measuring jaw 9 is tangent with filtration paper cylinder 2 all the time under the effect of spring 7; When filtration paper cylinder 2 diameters are reduced to the scope of setting; Target plate 8 has just got into the surveyed area of sensor 12; Sensor 12 output signals, notification processor filter paper is about to use up.
When changing filtration paper cylinder 2, measuring jaw 9 is pulled upwardly, pilot bar 5 can upward movement in linear bearing 4, and measuring jaw 9 turns to a side during to the relevant position, and the filtration paper cylinder 2 that more renews returns to control position with measuring jaw 9 and gets final product.
