Abstract

The utility model provides a prevent stifled vibrations sieve for tobacco screening, aim at solve traditional through type mesh and cause the problem of blockking up and need consumeing manual cleaning easily, and the scheme is the base plate of making including the rigid material, is equipped with the mesh on the base plate, the mesh be the rectangle mesh, one side downward sloping of mesh is extended there is the fin, the fin equal the half the of mesh area for rectangle and its projected area on the base plate, the angle between the horizontal plane of fin and base plate is 10-20, the orientation and the discharge gate of fin belong to opposite direction, the utility model discloses when specifically using, large stretch of pipe tobacco / smoked sheet is behind calorie income mesh, and when vibrations were controlled to the shale shaker, the production impelled large stretch of pipe tobacco of card income or the mesh that the smoked sheet breaks away from card income along the trend that the fin that slopes upwards climbed, and tiny pipe tobacco / smoked sheet is then realize screening below not fallen into by the mesh part of fin cover.

Description

For the anti-blocking vibrating sieve plate of tobacco screening

Technical field

The utility model relates to sieve plate, particularly relates to a kind of anti-blocking vibrating sieve plate for tobacco screening.

Background technology

In tobacco processing course, the size of smoked sheet and the chopping technique of the uniformity on the pipe tobacco later stage have the impact of high degree, if the higher long filament rate of pipe tobacco that will cause of smoked sheet large smoked sheet rate in early stage is higher, thus causes occurring quality problems in tobacco coiling process.

Therefore after the early stage of carrying out chopping tobacco and chopping, all need to sieve smoked sheet or pipe tobacco, be about to more large stretch of pipe tobacco/smoked sheet and be separated with broken cigarette/little smoked sheet.In traditional operation, normally by vibrating screen panel/sieve plate, vibrations screening is carried out to smoked sheet/pipe tobacco, the mesh of traditional woven screen or steel plate stamping hole sizer plate is normal mesh, this kind of mesh is in the process of application, pipe tobacco/the smoked sheet large stretch of along with the carrying out of operation easily partly snaps in mesh, and tiny pipe tobacco/smoked sheet can block mesh further because of the large stretch of smoked sheet/pipe tobacco snapped in, mesh blocking in the course of time can be more and more serious.Therefore traditional general expression mesh is very easy to result in blockage, and needs manually constantly to clear up mesh.

Summary of the invention

For above-mentioned situation, for overcoming the defect of prior art, the object of the utility model is just to provide a kind of anti-blocking vibrating sieve plate for tobacco screening, and object is the problem that the traditional through type mesh of solution easily results in blockage and needs labor intensive to clear up.

Its technical scheme is, comprise the substrate that rigid material is made, substrate is provided with mesh, described mesh is quadratic mesh, one side of mesh is downward-sloping is extended with fin, described fin is rectangle and its projected area on substrate equals the half of mesh area, and the angle between fin and the horizontal plane of substrate is 10 ~ 20 °, fin towards contrary with direction, discharging opening place.

Described substrate is made up of stainless steel material.

Its bond length of described mesh is 1.2mm, and long edge lengths is 2.4mm, and mesh is punch forming at twice, and a punching press forms the wide square opening of 1.2mm, the basis of square opening is carried out two times punch and forms the fin of inclination.

Described mesh triangularity is staggered formation array.

The utility model is when specifically using, large stretch of pipe tobacco/smoked sheet is after snapping in mesh, when shaking about vibratory sieve, produce the trend of upwards climbing along the fin tilted, impel large stretch of pipe tobacco of snapping in or smoked sheet to depart from the mesh snapped in, tiny pipe tobacco/smoked sheet then realizes screening by not fallen into below by the mesh-portion that fin covers.

Detailed description of the invention

Below in conjunction with accompanying drawing, detailed description of the invention of the present utility model is described in further detail.

Extract 100 mesh for the object of observation with random site on substrate, add up at vibratory sieve under the operating mode of 2 continuous throughout the twenty-four hour24 times, different angles fin mesh stopping state makes experiment form:

Angle of fins	Object of observation number	Blocking mesh number	Plugging rate (blocking mesh count/observation mesh count)
				10°	100	8	0.07
12°	100	6	0.06
				14°	100	2	0.02
16°	100	2	0.04
				18°	100	6	0.06
20°	100	8	0.06

By the data analysis of testing form above, when the angle of fin is 14 ° ~ 16 °, blocking mesh number reaches minimum, can reach best blocking-proof result.

Embodiment one: as shown in Figures 1 to 5, for the anti-blocking vibrating sieve plate of tobacco screening, comprise the substrate 1 that stainless steel material is made, substrate 1 is provided with mesh 2, described mesh 2 is quadratic mesh 2, the wide 2.4mm of mesh 21.2mm is long, one side of mesh 2 is downward-sloping is extended with fin 3, mesh 2 punch forming at twice, a punching press forms the wide square opening of 1.2mm, the basis of square opening is carried out two times punch and forms the fin 3 of inclination, described fin 3 is rectangle and its projected area on substrate 1 equals the half of mesh 2 area, angle between the horizontal plane of fin 3 and substrate 1 is 14 °, fin 3 also can be 10 ° or 20 ° with the angle of substrate 1, fin 3 towards contrary with direction, discharging opening place.Described mesh 2 triangularity is staggered formation array.
