Abstract

The utility model relates to a bidirectional beating device of a tobacco leaf beater, which belongs to the technical field of tobacco machinery and is used for solving the problem of bidirectional rotation of a leaf beating movable knife. The utility model comprises a machine frame, a shell, a knife roller, a fixed knife and a basket fence, wherein the knife roller and the fixed knife are positioned in the shell and the movable knives are evenly positioned on the knife roller while the basket fence is positioned at the lower part of the knife roller. The improvement lies in that the shell is symmetrically arranged long the center of the knife roller and the shell comprises a blanking section and a leaf beating transition section, the leaf beating transition section is a circular arc camber which forms a diametral clearance with one end of the movable knife. The utility model realizes the bidirectional leaf beating by improving the shell structure, and the main characteristics are that 1, the service life of the knife and the basket fence is improved by one time; 2, the utility model has simple structure, low manufacture cost and convenient operation; 3, a small quantity of chimney soot on the knife back can b cleared at any time, and the block-shaped chimney soot mixed in the leaves can be avoided; 4, the chimney soot stuck on the knife edge is reduced, the tearing ability of the knife edge to the tobacco leaves is enhanced, and the leaf beating efficiency is improved; 5, the maintenance time for the equipment is decreased, and the work efficiency is raised.

Description

The two-way leaf device of beating of tobacco threshing device

Technical field

The utility model relates to a kind of tobacco processing equipment, especially for beating leaf device, genus machine for processing tobacco technical field on the defoliator that separates tobacco leaf, leaf stalk.

Background technology

In the tobacco industry, tobacco leaf is smashed, separate blade leaf stalk, to reclaim blade be the preorder operation of whole tobacco processing course, also is one important procedure that influences tobacco quality.Tobacco processing factory generally uses the formation of defoliator to comprise that dozen leaf device, conveying device, wind divide device etc. at present, wherein, beating the leaf device is made up of housing, moving knife, quiet cutter, basket hurdle, tobacco leaf is splitting tearing through the quiet cutter of moving knife in housing, pulverize to sheet, enter wind through grid-shaped basket hurdle by conveying device again and divide device.The common moving knife of beating the leaf device is an one-directional rotation, and housing is designed to asymmetric eccentric shape, is beneficial to feeding intake, move and preventing putty of tobacco leaf.The problem that exists is: 1. crock accumulates seriously on the moving knife knife back face, needs often to shut down to change, clear up, and time and effort consuming has a strong impact on the operating rate of defoliator; 2. the large stretch of crock on the knife back comes off to sneak in the tobacco leaf and can have a strong impact on quality of tobacco; 3. moving knife and basket hurdle one-way abrasion are short service life.Based on the problems referred to above, improve the structure of existing apparatus, change cutter one-directional rotation is two-way rotation, for enhancing productivity, prolong service life of equipment, improving the tobacco leaf crudy crucial meaning is all arranged.

Summary of the invention

The utility model is used to overcome the defective of prior art and provides a kind of simple in structure, easy to operate tobacco threshing device the two-way leaf device of beating.

The alleged problem of the utility model is solved by following technical scheme:

The two-way leaf device of beating of a kind of tobacco threshing device, comprise frame, housing, rotor, stationary knife, basket hurdle in the formation, wherein, rotor, stationary knife are arranged in housing, moving knife is distributed on the rotor, and the basket field is in the rotor bottom, and its special feature is: described housing 10 is symmetrical arranged along the rotor center, by blanking section 10-1 with beat leaf changeover portion 10-2 and form, the described leaf changeover portion of beating is a circular arc camber, and radial clearance is left in this circular arc camber and moving knife end.

The two-way leaf device of beating of above-mentioned tobacco threshing device, described circular arc camber geometric center and rotor 12 centers of rotation of beating leaf changeover portion 10-2 have an eccentric distance e on short transverse, and its offset is 5～25 millimeters.

The two-way leaf device of beating of above-mentioned tobacco threshing device, described blanking section is provided with grade flitch 11, and the shelves flitch is fixed on two inwalls of blanking section 10-1.

The utility model by improving shell structure, is realized the two-way leaf of beating according to common tobacco threshing apparatus moving knife, stationary knife, the symmetrically arranged characteristics in basket hurdle, and its main feature is as follows: 1. doubled the service life on cutter, basket hurdle; 2. simple in structure, be easy to realize, cost of manufacture is cheap, is convenient to operation; 3. by the two-way rotation of moving knife, can remove a small amount of crock that is bonded on the knife back at any time, avoid block crock to sneak in the blade, these crock disintegrating slags are promptly separated with the leaf stalk, therefore can improve the tobacco leaf crudy; 4. regularly commutate repeatedly and beat leaf, reduce sticky crock on blade, strengthen the tear ability of blade, improve and beat leaf efficient tobacco leaf; 5. reduce equipment maintenance time and the artificial labour intensity of removing crock.Based on These characteristics, the utility model both had been applicable to does new equipment production, is applicable to again and does old scrap build.

Description of drawings

Fig. 1 is the schematic diagram of tobacco threshing device;

Fig. 2 is a structural representation of the present utility model.

The label of each parts is expressed as follows in the accompanying drawing: 1. feeding-distribution device; 2. conveying device; 3. wind divides device; 5. beat the leaf device; The basket hurdle; 7. frame; 8. stationary knife; 9. moving knife; 10. housing; 10-1. blanking section; 10-2. beat the leaf changeover portion; 11. shelves flitch; 12. rotor.

The specific embodiment

Consult Fig. 1, the formation of tobacco threshing device mainly comprises feeding-distribution device 1, beats leaf device 5, conveying device 2, wind are divided device 3, feeding-distribution device is transported to each respectively with raw tobacco and beats in the leaf device, tobacco leaf economy-combat leaf device is pulverized is sheet, divide device by entering wind by conveying device again through the basket hurdle, wind divides device to isolate leaf stalk and foreign material, and blade reclaims.

Consult Fig. 2, comprise frame 7, housing 10, rotor 12, stationary knife 8, basket hurdle 6 in the formation of the present utility model, wherein, rotor, stationary knife are arranged in housing, and moving knife 9 is distributed on the rotor, and the basket field is in the rotor bottom.As seen from Figure 2, housing is symmetrical arranged along the rotor center, by blanking section 10-1 with beat leaf changeover portion 10-2 and form, beating the leaf changeover portion is circular arc camber, the geometric center of this circular arc camber and rotor center of rotation have an eccentric distance e on short transverse, because the existence of this eccentric throw, make that the radial clearance of circular arc camber and moving knife end is the little down big displacement of, this structure helps preventing putty, and can improve the tear ability of blade to tobacco leaf.According to the equipment of different size, the offset of eccentric distance e is 5～25 millimeters.

Still consult Fig. 2, be rotated in the blanking section with moving knife and upwards fly upward for reducing blade, can grade flitch 11 be set in the blanking section, a shelves flitch is fixed on two inwalls of blanking section, the inwall of blanking section can be vertical setting as shown in the figure, also can be size suitable for reading being obliquely installed less than the end opening size.

During production, the direction of rotation that only need regularly change drive motors gets final product.
