Abstract

The invention discloses a synchronous embedded high-speed separating device which is used for separating letters from one another and comprises a group of letter conveying wheels (1), a group of shifting wheels (7), a group of damping wheels (5) and a letter guide plate (3) with damping. The letter guide plate (3) is arranged at the front of the shifting wheels and the damping wheels, and the rotation speeds, the linear speeds and the angular speeds of the letter conveying wheels and the shifting wheels keep identical constantly; two output letters are damped by the letter guide plate, so that a letter stream is in the shape of a combination of stacked tiles; the shifting wheels and the damping wheels form mutually embedded separating mechanisms but are not in contact with one another, so that a gap between each two adjacent letters is kept; the shifting wheels rotate towards a letter output direction, the damping wheels do not rotate, and accordingly the letters can be separated from one another at a high speed owing to the double-wheel embedded mechanisms. The shifting wheels and the damping wheels are embedded with one another pairwise, so that the letters to be separated slightly deform, the upper grouped damping wheels realize an effect of blocking output of an upper letter when two letters are simultaneously fed, and the shifting wheels output the bottom letters one by one.

Summary of the invention

The technical problem to be solved in the present invention is the deficiency that overcomes current tables of equipment sealed separating mechanism, and a kind of fricting separating device of high speed is provided.

In order to solve the problems of the technologies described above, the present invention adopts following technical scheme to realize: a kind of synchronous chimeric high speed separating device, comprise one group of deliver letters wheel and one group of dial wheel, and two kinds of wheels remain that rotating speed, linear velocity and cireular frequency are identical; Being equipped with one on the wheel part circumference identical with the dial wheel phase place of delivering letters has one fixed width, larger, the conveniently detachable circular arc rubber of friction coefficient, so that single letter that seals that the wheel of delivering letters is sent is connected with dial wheel, and synchronous transport; After dial wheel is exported this envelope letter and sent into pinch wheel, the wheel of delivering letters is sent the second envelope letter again.As a kind of of technique scheme, supplement, the place ahead of described damping wheel is provided with envelope-guiding plate, the output of envelope-guiding plate function damping two envelope letters, and make bottom output letter flow form imbricate, be convenient to single envelope and separate.

Chimeric separation device is one group of dial wheel and one group of damping wheel, and two damping wheels are one group, with a dial wheel pairing, forms single inserted type Separate With Friction mechanism; Make like this letter generation slight deformation to be separated, be conducive to realize single envelope separation.Dial wheel and damping wheel form micro chimerism formula separation device, keep the approximately gap of an envelope letter.The mechanism of this two-wheeled pairing, directly do not contact between damping wheel and dial wheel, not easy to wear, can realize high-speed separation..

Dial wheel is group formula structure.The effect of this circular arc dial wheel is that the letter one envelope envelope that the wheel of delivering letters is sent here is dialled from going out, and sends into pinch wheel.

As the another kind of preferred version of technique scheme, described damping wheel is designed to mechanism that can be unsteady, in order to separate the letter of became uneven; Stud with a rubber round belt that plays shock damping action on each damping wheel, pass through to stop two envelope letters simultaneously.

The accompanying drawing explanation

Below in conjunction with the drawings and the specific embodiments, the present invention is described in further detail.

Fig. 1 is the structural representation of synchronous chimeric high speed separating device of the present invention.

Fig. 2 is the axial, cross-sectional view of synchronous chimeric high speed separating device of the present invention.

The specific embodiment

As shown in Figure 1, the wheel 1 of delivering letters is taken turns and is remained that rotating speed, linear velocity and cireular frequency are identical with 7 liang of dial wheels group; One folded letter 2 is placed on letter feeder 9, and under the effect of positive pressure, the rotation of the wheel 1 of delivering letters is extracted an envelope envelope letter 2 of letter feeder 9 bottoms out through the effect of circular arc rubber 8 friction force, delivers to dial wheel 7 and damping wheel 5 interdigitating sections.Because the wheel 1 of delivering letters is identical with circular arc rubber 8 phase places that dial wheel 7 is equipped with on the part circumference separately, rotational synchronization, to deliver letters and take turns 1 and often turn around, circular arc rubber 8 can only be extracted an envelope letter 2 out, and is smooth side on all the other circumference, the minimum letter 2 of can not extracting out of friction force; In like manner the dial wheel 7 circular arc rubber 8 that often turns around also can only be exported the envelope letter 2 that the wheel 1 of delivering letters is extracted out; The wheel 1 of delivering letters rotates continuously with dial wheel 7, and letter 2 is just by single envelope output continuously.Be provided with envelope-guiding plate 3 in the place ahead of damping wheel 5, damping rubber 4 is housed below envelope-guiding plate, limit under the effect in gap at it, not only hindered and pulled two envelope letters outputs but also make letter feeder 9 bottom letter flows form imbricates, make single envelope letter deliver to dial wheel 7 and damping wheel 5 interdigitating sections.Damping wheel 5 is parallel with the axis of dial wheel 7, damping wheel 5 two ends are provided with the rubber round belt 6 that diameter is slightly large, the less formation groove of the middle part diameter of damping wheel 5, shorter and the micro chimerism of circular arc rubber 8 width of dial wheel 7 is in the groove of damping wheel 5, but do not contact each other, keep the approximately gap of an envelope letter, even there are two envelope letters to send, also dampedly take turns 5 and stop, make the single envelope of dial wheel 7 output letters.

Enter damping wheel 5 and dial wheel 7 interdigitating sections, the coefficient of friction of its circular arc rubber 8 is greater than the coefficient of friction of damping wheel rubber round belt 6, even there are two an envelope letter concordant letter to enter the groove of damping wheel 5, under the friction effect of circular arc rubber 8, letter 2 just can be dialled from out by an envelope envelope, sends into pinch wheel place, rear portion.Damping wheel 5 is relocation mechanism, with the letter 2 that adapts to became uneven, passes through.The radical function of dial wheel 7 is under the effect of damping wheel 5, and letter 2 is produced to positive pressures, makes that letter 2 is micro-distortion, and makes letter one envelope envelope form fixing pitch to dial from out.In order to reach this function, in the concrete structure design, the unsteady damping wheel mechanism of employing group formula, pass through with the letter that adapts to 0.3-8mm.Without letter by the time, between damping wheel 5 and dial wheel 7, directly contact, when letter 2 passes through, damping wheel 5 only contacts with letter 2 with dial wheel 7, wear and tear little, thus the separation efficiency of letter can increase substantially, the enforcement high-speed separation.
