Abstract

FIELD: soft wares, paper.

SUBSTANCE: device for dast-fibered material preprocessing contains holding conveyor, double scutching drums with tapered and cylindrical sections, in each of scotching sections guarding enclosure is implemented. It coincides by shape with scutching drums felling cutter path, loading hopper lengthwise of scutching sphere with directional screen at its upper end, left and right in every scutching section flexible restraint are installed. It separates areas with cylindrical section from areas with tapered section of double scutching drums.

EFFECT: machine productivity improvement for dast-fibered material preprocessing.

Description

The invention relates to the primary processing of bast fiber material, mainly flax trusts, for devices for scrubbing washed stalk bast fiber material using bobbin machines.

A device for producing a long fiber containing paired drums, a conveyor and bins for the removal of waste scuffing [1].

The disadvantage of this device is the large air volume in the baffle sections with random flows during the removal of basting waste by the pneumatic conveying system, which leads to the formation of coils on the bobbin drums and a decrease in productivity.

A device for de-sharpening long-fiber complexes with clamping and transporting belts and beat drums [2]. The authors analyze the causes of windings in a bobbin machine, provide recommendations for dealing with them. The recommendations are of a private nature and do not exclude the randomness of the movement of air flows in the trepid sections, leading to the formation of coils.

The closest in technical essence to the proposed invention is a device for the primary processing of bast-fiber material [3]. According to the patent RU 2250939, D01B 1/14, 2005, the device comprises a conveyor, paired scraper drums with conical and cylindrical parts, in each scraper section a protective casing is made that coincides in shape with the trajectory of the scraper drum blades to form a closed limited air volume along the sphere a receiving funnel is installed, along the upper edges of which there are elastic guide visors. The patent does not eliminate the occurring movement of scuffing waste from the cylindrical parts of the scuffing drums along their conical parts onto the shafts of the scuffing drums.

The objective of the invention is to increase the productivity of the bobbin machine by reducing downtime for cleaning the shafts of bobbin drums.

The technical result, which consists in eliminating these shortcomings in the device for the primary processing of bast-fiber material, containing a clamping conveyor, paired scraper drums with conical and cylindrical parts, in each scraper section a guard is made that matches the shape of the trajectory of the beating knives of the scraper drums, a receiving funnel along spheres of scuffing with guiding visors along its upper edges, is achieved due to the fact that elast egg restraints separating zones with cylindrical parts from zones with conical parts of paired bobbin drums.

The device is illustrated by drawings.

Figure 1 - General view of the device.

Figure 2 is the same side view.

A device for primary processing of bast-fiber material contains a clamping conveyor 1, a pair of scraper drums 2 with beater knives 3, a receiving funnel 4 with guide peaks 5, elastic stops 6 and a casing enclosing 7; each scraper drum includes a cylindrical part 8 and a conical part 9.

The device operates as follows. The washed layer of stalks of bast-fiber material by the clamping conveyor 1 is introduced into the working area of the scrubbing drums 2 and is sharpened by beating knives 3, the scuffing waste enters the receiving funnel 4, which has guide peaks on the upper edges 5. To prevent the scuffing waste from the cylindrical part 8 of the scuffing drum, where the largest amount of waste is allocated, on the conical part 9, along which the fibers are moved to the shaft of the scraper drum and form a winding, left and right scutch sections are installed 6. The elastic rib guides limiters, for example, felt, closely adjacent the picker drums and prevent movement of waste along the scutching scutching structural elements sections. The left and right elastic limiters 6 are installed at the top to the support of the clamping conveyor 1, at the bottom - to the guide visors 5. The elastic limiters reduce the randomness of the air flow in the tremp section of the specified design with division into 3 zones, also reducing the number of broken fibers breaking. The installation of elastic limiters is applicable in scutch sections with scraper drums of a different design, for example, barrel-shaped, as well as with one-sided scuffing. The layer of stalks of bast-fibrous material is de-sharpened by rotating beater knives 3 of scraper drums 2 in a closed working zone created by a casing enclosing 7, the shape of which coincides with the trajectory of beater knives of scraper drums.
