Abstract

The utility model provides a dough like raw material cutter. Thread pitch of an original threaded rod conveying device is changed from an equidistance into variable pitch with a big head end and a few tail end to form the extrusion force of material, and a charge discharging gap is arranged between a screw thread and a feeding container wall. Rotary distribution material is arranged in an original quantitative container and can carry out rotation of 90 DEG in the quantitative container to realize two stations. The station 1 is that a feed port is opened and a discharge port is closed, and the station 2 is that the feed port is closed and the discharge port is opened to ensure that cutting materials is not disturbed by feeding. The utility model ensures the accuracy and the uniformity of the cutting of plant fiber material.

Description

Dough shape raw material cutting machine

The utility model relates to the plant equipment that a kind of dough shape raw material cutting machine, particularly plant fiber products divide blank.

Plant fiber products be with the straw of annual herb plant as rice wheat straw, reed, bagasse, be equipped with certain auxiliary material, adding water, to stir into doughy material be raw material.On special-purpose machinery, can produce disposable food or beverage container, odds and ends splendid attire vessel, the shockproof goods of packing etc.Because the dough shape raw material that Vegetrable fibre material is become after stirring, viscosity is big, material matter is loose and all degree differ, also contain a large amount of bubbles, cause in cutting machine in the past, exist quantitatively and forbidden, expect that piece and material piece stick together, fiber is pullled difficult problems such as being difficult for cut-out.

The purpose of this utility model is: in the string depiler, design the balanced material density of a kind of energy, accurately provide quantitatively, realize the agile raw material cutting machine of not pasting of blank.

The utility model is achieved in that this dough shape raw material cutting machine, mainly comprise screw rod pusher 1, loading hopper 2, feeding container chamber 3, dosing container 4, tapping channel 5, cutting knife 6, its screw rod pusher 1 places the feeding container chamber, loading hopper 2 communicates with it at the head end upside in feeding container chamber, dosing container 4 communicates with port at the tail end in feeding container chamber, the pitch that its screw rod pusher (1) is gone up screw thread from large to small, spiral shell spin and the feeding container cavity wall between the gap of being convenient to rush down lotus is arranged.

Above-mentioned dough shape raw material cutting machine, in its dosing container 4 rotary tripper 7 is housed, the rotary tripper inner chamber is the threeway form, by external power rotatable 90 °, be in two stations respectively, a station is in the charging aperture 4-1 that makes dosing container 4 and communicates with feeding container chamber 3, discharging opening 4-2 sealing, another station is to open discharging opening 4-2 to communicate with tapping channel 5, sealing charging aperture 4-1.

Above-mentioned dough shape raw material cutting machine, the head end pitch of its screw rod pusher is 1: 0.5: 0.8 with the ratio of tail end pitch.The sword limit of cutting knife 6 is that the angle α of zigzag and its direction of advance is 40 °～60 °, makes blade progressively cut material.

The utility model has the advantages that: adopt varying pitch screw that material is had squeezing action, extrude bubble, make material density when entering dosing container even, the lotus effect of rushing down has been pushed to the bending moment screw rod in the lotus gap of rushing down of screw thread blade and feeding container cavity wall, has guaranteed carrying out smoothly of extrusion process.Rotary tripper is closed the degree of accuracy that discharging opening has guaranteed inlet amount when charging; Closed charging aperture during discharging, guaranteed that not only the weighing apparatus of material pressure is fixed before the charging aperture, and the inaccuracy that causes is interfered in charging when having prevented discharging.Therefore this programme is to containing cutting accurately evenly of bubble or loose bulk material, and the angle of cutting knife and its direction of advance helps the cutting of fibroid raw material.

Below accompanying drawing is described: Fig. 1 is a structural representation of the present utility model, and 1 is screw rod pusher, the 2nd among the figure, and loading hopper, the 3rd, feeding container chamber, 3-1 are to rush down lotus gap, the 4th, and dosing container, 4-1 are that charging aperture, 4-2 are discharging openings, the 5th, and tapping channel, the 6th, cutting knife, 6-1 are knife rests, the 7th, rotary tripper, the 8th, and material is released cylinder, the 9th, cutting knife cylinder.Fig. 2 is the cutter schematic top plan view, the 6th, and cutting knife, arrow are represented the cutting knife travel direction, and 10 represent the material cross section.

Further specify the embodiment of the present utility model and the course of work below in conjunction with accompanying drawing: it mainly contains the Variable pitch screw pusher 1 of convey materials, loading hopper 2, feeding container chamber 3, adjustable dosing container 4, rotary tripper 7, tapping channel 5, knife rest 6-1, cutting knife 6 and driving control system.Displacement pusher 1 places feeding container chamber 3, and and feeding container 3 inwalls between remain with gap 3-1, be convenient to rush down lotus.Screw thread blade convey materials when Variable pitch screw pusher 1 rotates, because displacement pusher pitch from large to small, the air in the material is discharged in the extruding of level level during work, to improve material density.Because rush down the existence in lotus gap, pressure can infinitely not increase, and has guaranteed to hold thus the material pressure that enters dosing container constant, and rotary tripper is done 90 ° of rotations off and on, when it is in charging aperture 4-1 and opens operating mode, material is got into dosing container 4, and rotary tripper rotates 90 °, and charging aperture 4-1 closes, open discharging opening 4-2, cylinder 8 is released the raw material after quantitative in the dosing container, and cutter is also back and forth done cutting action simultaneously, and raw material is downcut.Driving control system (containing motor, compressed air) provides operation power, the control working procedure.

On the adjustable dosing container adjustment screw is arranged, can control the volume of cutting material.

Cutter is installed in dosing container tapping channel 5 one ends, carries out cutting action by cylinder 9.This cutter is oblique sword formula sawtooth cutting tool, can be efficiently with the fibre cutting in the material.

Further specify the course of work below in conjunction with embodiment: raw material is put into funnel, the variable-pitch propeller pusher will expect that sending into pusher from head end delivers to the tail end in feeding container chamber with it, form certain pressure, bubble is extruded, rotary tripper is opened charging aperture, material enters dosing container, after container is added completely quantitatively, rotary tripper rotates 90 ° and closes charging aperture, starts material and releases cylinder 8, and the material in the container can be pushed out under no charging is interfered, cutting knife cylinder operation then, cutting knife cuts off it, and this moment, tripper was got back to the logical position of charging aperture again, repeated above action.

The rotation of rotary tripper is finished by external power, and is as the rack and pinion mode that the axle that the rotation sub-material is clamored is coaxial with gear, moves along tooth bar with the cylinder driven gear, regulates the tram that its distance of moving on tooth bar can guarantee two stations.How many big I of the pitch of screw rod pusher and displacement adjusts according to the viscosity of material, density, bubble, when being used for the string material, head end pitch ratio tail end pitch be about 1: 0.6 best.Each dynamical system is controlled the rhythm of its operation program by control system.
