Abstract

The utility model discloses an improved structure of a broken tobacco impurity removal sieve plate, belonging to a vibrating sieving device. The vibrating screen comprises a screen plate which is obliquely fixed in a vibrating screen groove along the moving direction of materials; the surface of the screen plate (2) is fixedly provided with a plurality of groups of blocking devices distributed along the movement direction of the materials, and each blocking device consists of a mounting strip (5) fixed on the surface of the screen plate (2) and a plurality of stoppers (3) which are fixedly arranged on the mounting strip along the width direction of the vibration screening groove (1) and are in a 'dry' -shaped structure; a plurality of saw-toothed barbs are distributed on one side of the stopper (3) in the reverse material movement direction. The utility model has the advantages of simple structure, convenient processing and manufacturing, low running cost, good impurity removing effect, less tobacco loss and the like. Is a sieve plate capable of eliminating fibrous light impurities mixed in the broken tobacco leaves.

Description

Improved structure of broken tobacco impurity removing screen plate

Technical Field

The utility model relates to a piece tobacco leaf impurity removal sieve plate, in particular to an improved structure of the piece tobacco leaf impurity removal sieve plate.

Background

The vibrating screen is a main device for removing sundries in the tobacco redrying process, and is generally composed of a screen plate which is obliquely fixed in a vibrating screen groove along the moving direction of materials. The sieve plate with the traditional structure can only remove impurities with heavier mass, such as soil, tobacco stems and the like and smaller grain size; the fiber-shaped light non-smoke sundries such as cotton threads, hemp velvet, hair and the like are difficult to remove. Although the fibrous light sundries mixed in the tobacco leaves can be removed by adopting a manual picking mode, the defects of high labor intensity, low efficiency, fluctuation of picking effect due to influence of human factors and the like exist.

In order to overcome the defects, the patent document with the publication number of CN 212678326U discloses a crushed tobacco leaf winnowing impurity removing device. Although the patent can remove lighter impurities, it is difficult to remove fibrous impurities such as cotton, hemp and hair. The reason for this is that fibrous impurities are easily entangled with tobacco leaves and are difficult to separate from each other. In addition, the winnowing impurity removing device has the defects of complex structure, high operation cost, easiness in blowing away small tobacco leaves along with impurities and serious waste of the tobacco leaves.

Disclosure of Invention

Aiming at the defects in the prior art, the utility model aims to provide an improved structure of a broken tobacco impurity removing sieve plate with good impurity removing effect, and the improved sieve plate can better separate tobacco from fibrous light impurities.

In order to achieve the above purpose, the present utility model adopts the following technical scheme: the vibrating screen comprises a screen plate which is obliquely fixed in a vibrating screen groove along the moving direction of materials; the surface of the screen plate is fixedly provided with a plurality of groups of blocking devices distributed along the movement direction of the material, the blocking devices are composed of a mounting strip fixed on the surface of the screen plate and a plurality of stoppers which are arranged on the mounting strip along the width direction of the vibration screening groove and are in a 'dry' -shaped structure, and a plurality of barbs which are in a zigzag shape are distributed on one side of the stoppers, which are in the reverse direction of the movement direction of the material.

The stoppers in the technical scheme are obliquely arranged relative to the surface of the sieve plate in an upward tilting way, and the stoppers on two adjacent groups of blocking devices are arranged in a staggered way.

Further, a blocking block which is in a wedge-shaped structure and is fixed on the mounting strip is arranged between every two adjacent blocking devices, and a plurality of barbs which are in a saw-tooth shape are distributed on the inclined surface of the blocking block.

Compared with the prior art, the utility model has the following advantages due to the adoption of the technical scheme: when the broken tobacco leaves are hindered by a plurality of groups of stoppers in the vibration screening movement, a plurality of barbs distributed on the stoppers can adhere to fibrous impurities such as cotton filaments, hemp velvet, hair and the like mixed in the broken tobacco leaves, so that the fibrous impurities mixed and entangled in the broken tobacco leaves can be removed, and the separation of the fibrous impurities and the broken tobacco leaves can be realized step by step. Thoroughly avoid the wind separation edulcoration device structure complicacy, running cost high, the small tobacco leaf is blown away along with impurity easily, and the tobacco leaf waste is serious, and edulcoration effect is not ideal defect.

Detailed Description

The utility model will be further described with reference to the drawings and specific examples.

As shown in fig. 1 to 5: the utility model comprises a screen plate which is obliquely fixed in a vibration screening groove along the movement direction of materials (namely the direction indicated by hollow arrow in figure 2); the surface of the sieve plate is fixedly provided with a plurality of groups of blocking devices distributed along the moving direction of the materials, and the blocking devices are composed of a mounting strip 5 fixed on the surface of the sieve plate 2 and a plurality of blocking devices 3 which are fixedly arranged on the mounting strip along the width direction of the vibration sieving groove 1 and are in a dry-shaped structure; a plurality of saw-toothed barbs (not shown) are distributed on one side of the surface of the stopper 3, which is opposite to the movement direction of the material.

In order to avoid that the material passes over the blocking means during vibration, the blocking means 3 are tilted upwards with respect to the surface of the screen deck 2; in order to ensure the impurity removal effect, the stoppers 3 on two adjacent groups of the stopper devices are arranged in a staggered manner along the width direction of the vibration screening groove 1.

In order to further improve the impurity removal effect, a blocking block 4 which is in a wedge-shaped structure and is fixed on the mounting strip 5 is arranged between every two adjacent blocking devices 3, and the inclined surface of the blocking block is distributed with a plurality of barbs which are in a saw-tooth shape.
