Description

Automatic sieving mechanism of ejection of compact

Technical Field

The utility model relates to a sieving mechanism especially relates to the screening of grit and crystal in the piezoelectric crystal trade process of falling limit.

Background

The piezoelectric crystal industry typically reduces the impedance by chamfering the periphery of the crystal. The existing chamfering process is to add the grinding sand and the crystal into a chamfering barrel together, and then to place the chamfering barrel into a chamfering machine to finish chamfering, but after the grinding sand grinds the crystal for a long time, the friction force of the crystal is reduced, and at the moment, the original grinding sand needs to be replaced and new grinding sand needs to be added. At present, the grinding sand and the crystals in the chamfering bucket are poured onto a screen together manually, the screen is shaken manually to complete the separation of the grinding sand and the crystals, and then the crystal grains are poured into the chamfering bucket to be added with new grinding sand. The manual operation has the defects of low efficiency, high labor intensity and the like.

Disclosure of Invention

An object of the utility model is to overcome prior art's shortcoming, provide one kind and divide the sieving mechanism who selects the crystalline grain in grit and crystalline grain mixture, and can accomplish the ejection of compact automatically.

The utility model relates to an automatic discharging screening device, which comprises a dustpan-shaped screen with an outlet at one end, wherein a steel wire mesh is arranged in the screen to divide the screen into an upper layer and a lower layer, wherein the upper layer is used for containing and conveying crystal grains, the lower layer is used for containing and conveying grinding sand, a container for collecting the grinding sand is arranged at the outlet of the lower layer of the sieve, a downstream collecting device is arranged at the outlet of the upper layer of the sieve, the bottom wall of the sieve is fixed on the vibration surface of the sand sieving vertical vibrator, a fixed plate is arranged below the sand screening direct vibration device and is arranged along the horizontal direction, springs are respectively connected at four corners between the fixed plate and the sand screening direct vibration device, wherein the height of the two inner springs close to the container side is smaller than that of the outer springs far away from the container side, so that the sieve and the sand sieving straight vibration device are obliquely arranged towards the outlet side of the sieve.

The utility model has the advantages that: adopt this structure can realize the material of two kinds of different diameters of autofilter, and can automatic discharge, replaced the manual work, improved work efficiency, reduced labour cost.

Detailed Description

The present application is described in detail below with reference to a specific embodiment and the attached drawings. However, the description is only a preferred embodiment of the present application and should not be considered as limiting the scope of the invention. All the equivalent changes and improvements made according to the application scope of the present invention should still fall within the patent coverage of the present invention.

The utility model discloses an automatic sieving mechanism of ejection of compact as shown in the attached drawing, including the dustpan shape sieve 1 that one end has the export, be provided with wire net 7 in the sieve 1 make the sieve divide into two-layer about, wherein the upper strata is used for holding and carrying the crystalline grain, the lower floor is used for holding and carrying the abrasive sand, sieve 1 lower floor exit install the container 6 that collects the abrasive sand and use, sieve upper exit be provided with the low reaches collection device, sieve 1 bottom wall fix on the vibration plane of the straight oscillator 3 of sieve sand, sieve sand straight oscillator 3 below set up fixed plate 5, fixed plate 5 set up along the horizontal direction, be connected with the spring respectively in the four corners department between fixed plate 5 and the straight oscillator 3 of sieve sand, wherein the height that is less than the outside spring 4 who keeps away from the container side of two inboard springs 2 that are close to the container side makes sieve 1 and the straight oscillator 3 of sieve sand incline to sieve 1 outlet side slope setting, this setting does benefit to crystalline grain and grit and carries forward, also can play the cushioning effect through the setting of two sets of springs and avoid the vibrations of sieve sand rectilinear vibration ware 3 to influence other devices.

When the sand screening vertical vibration device works, two mixed materials are added on the steel wire mesh 7, the sand screening vertical vibration device 3 is started, the two materials move forwards due to the existence of vibration and an inclination angle, and the materials (crystal grains) with the diameter larger than that of the steel wire mesh 7 move forwards from the upper layer until the materials slide out from an upper layer outlet and are transferred to other places or collected by a downstream device; less than the material (the emery) in 7 apertures of wire net, can follow wire net 7 and fall into the lower floor when the upper strata slides forward, final whole will be followed the export of lower floor and flowed, is collected by container 6.
