Abstract

The utility model discloses a tobacco leaf screening plant, including braced frame and supporting the many rollers that the parallel on braced frame was arranged side by side, each roller is rotated by the motor drive syntropy, the roller include roller body and axial interval arrangement in roller body peripheral surface's convex shoulder part, the convex shoulder part -Offset of two piece adjacent rollers. This device can improve screening efficiency, and it influences lower floor's screening effectively to avoid long tobacco leaf to be fallen down by the roller clearance.

Description

Tobacco leaf screening plant

Technical field

The utility model relates to the equipment on cigaret primacy processing line, is specially a kind of tobacco leaf screening plant.

Background technology

In current cigaret primacy processing line, be adopt vibrating screen classifier to sieve tobacco leaf mostly.Tobacco leaf drops on the sorting sieve plate of shutter by feed end, and larger tobacco leaf is fed forward by separating sieve panel vibration, and the tobacco leaf making size less and offal drop on the screen cloth that failure of oscillation is not dynamic of below, then carries out vibrosieve by screen cloth.But the screening efficiency of the sorting sieve plate of this shutter is very low, many larger-size tobacco leaves also can fall down from sorting plate, cause tobacco leaf bulk deposition on screen cloth, and the screening function of screen cloth is lost, and offal can not effectively be sieved.Further, this sorting sieve plate self is also easily blocked, affects screening effect.

As patent 201541697 discloses a kind of pipe tobacco cooling screening machine, which disclose a kind of star roll structure for transmission sorting tobacco leaves, it is the star roller of the many rotating in same directions be arranged side by side.This star roller body is prismatic straight cylinder, can form gap identical with star roller length together between two rollers, this gap is the passage that broken thin tobacco leaf and offal fall, but is unavoidably, long tobacco leaf is also easy to be fallen by this gap, thus have impact on screening effect.

Summary of the invention

The purpose of this utility model is to provide a kind of tobacco leaf screening plant, improves screening efficiency, effectively avoids long tobacco leaf to be fallen down by roller clearance.

Tobacco leaf screening plant described in the utility model, comprise support frame and the parallel many roll shafts be arranged side by side supported on the support frame, each roll shaft drives rotating in same direction by motor, described roll shaft comprises the convex shoulder part that roll shaft body and axially spaced-apart are arranged in roll shaft body peripheral surface, and the convex shoulder partial transposition of adjacent two roll shafts is arranged.

The convex shoulder partial transposition of described adjacent two roll shafts is arranged, refer to the convex shoulder part of a wherein roll shaft face adjacent two convex shoulders on the roll shaft that is adjacent divide between roll shaft body.

The convex shoulder part of every root roll shaft is between all on the roll shaft be adjacent, adjacent two convex shoulders are divided.

Preferably, described roll shaft body and convex shoulder are divided into cylinder or regular polygon cylinder.

Tobacco leaf screening plant described in the utility model, by changing the structure of roll shaft, makes adjacent two roll shafts rabbet cooperation mutually, thus rectangle wave-like gaps is formed between two roll shafts, both ensure that broken thin tobacco leaf dropped, and turn avoid long tobacco leaf and drop, effectively improve screening effect.

Accompanying drawing explanation

Fig. 1 is structural representation of the present utility model;

Fig. 2 is the matching relationship schematic diagram of adjacent two roll shafts;

Fig. 3 is the A-A profile of Fig. 2.

Detailed description of the invention

Below in conjunction with drawings and Examples, the utility model is described in further detail, and following examples, only for explaining the utility model, do not form the restriction to the utility model protection domain.

Tobacco leaf screening plant as Figure 1-3, comprise support frame 2 and the parallel many roll shafts 1 be arranged side by side supported on the support frame, each roll shaft drives rotating in same direction by motor.

Described roll shaft comprises the convex shoulder part 102 that roll shaft body 101 and axially spaced-apart are arranged in roll shaft body peripheral surface, the convex shoulder partial transposition of adjacent two roll shafts is arranged, the convex shoulder part 102 of every root roll shaft 1 is all on the roll shaft be adjacent between adjacent two convex shoulder parts 102.Make to define concavo-convex chimeric fit system between two roll shafts, thus between roll shaft, constitute the gap of class rectangle wave, both ensure that broken thin tobacco leaf drops, effectively avoided again long tobacco leaf and fall down.

The roll shaft body 101 of the present embodiment is cylinder, and convex shoulder part 102 is regular hexagon cylinder.Certainly, described roll shaft body also can for being less than the regular hexagon cylinder body shape of this convex shoulder part.

Claims

1. a tobacco leaf screening plant, comprise support frame (2) and the parallel many roll shafts (1) be arranged side by side supported on the support frame, each roll shaft drives rotating in same direction by motor, it is characterized in that: described roll shaft comprises the convex shoulder part (102) that roll shaft body (101) and axially spaced-apart are arranged in roll shaft body peripheral surface, the convex shoulder partial transposition of adjacent two roll shafts is arranged.

2. tobacco leaf screening plant according to claim 1, is characterized in that: the convex shoulder part (102) of every root roll shaft is between all on the roll shaft be adjacent, adjacent two convex shoulders are divided.
