Abstract

The invention discloses a mesh self-cleaning structure of a vibrating screen plate. The mesh self-cleaning structure is characterized in that rollers with a horizontal axis are arranged at the bottom of a horizontal screen plate, the tops of the rollers are accommodated in meshes of the screen plate, and the top surfaces do not exceed the upper surface of the screen plate. The diameter of the rollers is larger than that of the meshes of the screen plate, and material falling gaps are reserved between the peripheries of the meshes and the outer circumferential surfaces of the rollers. The rollers can rotate with the axis as the rotating center. The mesh self-cleaning structure of the vibrating screen plate can effectively relieve mesh plugging, and improve production efficiency and product quality stability.

Description

Oscillating screen plate mesh self-cleaning structure

Technical field

The present invention relates to a kind of oscillating screen plate mesh and put structure in order, is more particularly be applied in tobacco productive corporation, the mesh cleaning structure of oscillating screen plate of the sieve that carries out shaking for offal.

Background technology

Along with the development of tobacco business, oscillatory type screening machine, namely shake sieve use widely, shake sieve can effectively ensure production technology requirement, reduce to shake sieve the manual maintenance time etc. be to shake sieve performance higher requirement.In actual production, due to the adhesion of material, sieve plate clogging is serious, if can not clear up in time in work, then can greatly reduce screening efficiency extremely low, and the mode blocking mesh with labor cleaning in prior art have impact on production efficiency equally significantly, affects constant product quality.

Summary of the invention

The present invention is the weak point for avoiding existing for above-mentioned prior art, provides a kind of oscillating screen plate mesh self-cleaning structure, to reduce sieve plate clogging, enhances productivity, improve product quality stability.

The present invention is that technical solution problem adopts following technical scheme:

The feature of oscillating screen plate mesh self-cleaning structure of the present invention is: for being horizontally disposed sieve plate, arrange in the bottom of sieve plate the roller that axis is level, the bizet of described roller is contained in the mesh of sieve plate, and is preced with the upper surface that end face does not exceed sieve plate; The diameter arranging described roller is greater than the mesh diameter of sieve plate, between the periphery and the outer circumference surface of roller of the mesh of described sieve plate, maintain blanking gap; Described roller can be the rotatable roller of center of rotation with roller axis.

The feature of oscillating screen plate mesh self-cleaning structure of the present invention is also:

For each sieve plate mesh sieve plate located on the same axis, it is locate on the same axis equally that one_to_one corresponding arranges each roller; Described place each roller is on the same axis arranged in same Roller Shaft.

With described Roller Shaft for axle core, each roller sleeve is contained in Roller Shaft, between adjacent rollers with spacer separately.

The height of described Roller Shaft can regulate.

The height of described Roller Shaft is that vertical telescopic cylinder rod drives and regulates by the cylinder being positioned at Roller Shaft two ends with it; Described cylinder is supported on frame by air cylinder support, and described frame is vibratory sieve frame.

Compared with the prior art, beneficial effect of the present invention is embodied in:

1, the present invention can effectively reduce sieve plate clogging, enhances productivity, improves product quality stability.

2, in the present invention, the continuous rotation of roller achieves the self-cleaning of sieve plate mesh, can realize the non-maintaining of sieve plate, significantly reduce personnel labor intensity.

3, the present invention is simple and compact for structure, and the reliable operation of self-cleaning structure own, maintenance workload is minimum.

Accompanying drawing explanation

Fig. 1 is structural representation of the present invention;

Fig. 2 is self-cleaning principle schematic of the present invention;

Number in the figure: 1 air cylinder support, 2 cylinders, 3 locking nuts, 4 spacers, 5 rollers, 6 Roller Shaft, 7 cylinder rods, 8 adjusting nuts, 9 sieve plates, 10 frames, 11 offals, 12 meshes.

Detailed description of the invention

See Fig. 1, in the present embodiment, oscillating screen plate mesh self-cleaning vibrational power flow is: for being horizontally disposed sieve plate 9, arrange the roller 5 that axis is level in the bottom of sieve plate 9, the bizet of roller 5 is contained in the mesh of sieve plate 9, and is preced with the upper surface that end face does not exceed sieve plate 9; The diameter arranging roller 5 is greater than the mesh diameter of sieve plate 9, between the periphery and the outer circumference surface of roller 5 of the mesh of sieve plate 9, maintain blanking gap; Roller 5 can be the rotatable roller of center of rotation with roller axis.

For each sieve plate mesh sieve plate 9 located on the same axis, it is locate on the same axis equally that one_to_one corresponding arranges each roller 5; Place's each roller 5 is on the same axis arranged in same Roller Shaft 6.

Be axle core with Roller Shaft 6, each roller 5 is sleeved in Roller Shaft 6, between adjacent rollers with spacer 4 separately.

The height of Roller Shaft 6 can regulate, height about Roller Shaft 6 regulates, it is specifically that vertical telescopic cylinder rod 7 drives adjustment by the cylinder 2 being positioned at Roller Shaft two ends with it, and cylinder 2 is supported on frame 10 by air cylinder support 1, and frame 10 is vibratory sieve frame.

The present invention can not shut down and Automatic clearance bur under production status, ensures working stability and the normal operation of whole screening system, can effective guarantee equipment efficiency.For different step sizings, by the extension elongation of adjusting nut 8 and locking nut 3 control cylinder bar 7, to adjust the height of Roller Shaft 6 and then to regulate the height of roller to realize, operator only need start cylinder when clearing up sieve plate, step sizing is transferred to appropriate size, and exceed standard offal and fragment of size can all can fall.

As shown in Figure 2, self-cleaning principle in the present invention is, when not starting cylinder, roller 5 is in the mesh 12 of sieve plate, due to the existence in gap, offal 11 and the tiny foreign material such as tobacco cut chip and dust are fallen into lower sieve nest by the gap between roller 5 and sieve plate mesh 12 and are then discharged to shake and sieve, because roller is subject to entering the active force of offal 11 in mesh, during roller is in and ceaselessly rotates, the roller of this state is equivalent to dial brush and equally stirs the chip entering mesh and fall into lower sieve nest, avoids material sticks mesh; Part offal and tobacco cut cannot normally drop in lower sieve nest in mesh because being stuck in, the gap between cylinder increase roller and sieve plate mesh only need be started when its quantity acquires a certain degree, offal in mesh and tobacco cut will drop in lower sieve nest, realize mesh self-cleaning.
