Description

Sugar refined sugar machines are known, including a table for splitting sugar bars mounted on a common bed, two flat-blades moving back and forth in the vertical plane, two endless lamellar chains with strips for feeding the bars to the split and spring-loaded clamps to hold the bars in the split process .

The proposed rafter sugar refining machine has the following advantages compared with the known machines: the splitting of sugar bars is performed in a continuous stream, which makes it possible to create a line with a press-drying unit; feeding the bars to a mechanized rift, sugar bars splitting into pieces with a smoother surface with less sugar; machine is more productive.

For the purpose of the machine, a part of the air cushion with intermittent movement of the conveyor of the pressing and base assembly is installed, equipped with a bar limiting and compacting the portion of the bars prepared for splitting; in the direction perpendicular to the conveyor belt, a return apron is installed to drop the collected portion of the bars from the belt to the table for splitting.

Knife holders are fixed in shafts with eccentrically located trunnions, which ensures the movement of knives in the direction of movement of the bars and with leading speed.

FIG. Figure 1 shows the kinematic diagram of a peeler for refined sugar; in fig. 2 - machine diagram, side view; in fig. 3 is a plan view of the machine; in fig. 4 is a diagram of the mutual arrangement of flat knives in the machine and their drive; in fig. 5 is a section along AA in FIG. four; in fig. 6 - the technological scheme of the split of the bars of the sugar refinery.

The main working bodies of the machine are: two flat knives 1 and 2, splitting bars 3 of refined sugar into pieces 4

No. 146257-2 (Fig. 6); part of the belt conveyor 5 of the pressing-drying unit mounted into the machine diagram; a returnable apron 6 serving to drop a portion of sugar bars from the conveyor belt 5 to the table 7 for splitting; two endless lamellar chains 8 and 9 with transverse straps 10 for supplying sugar bars to the knives / and 2; and spring-loaded clips //, designed to hold the sugar bars during their splitting into pieces.

The knives / and 2 are installed in strips (holders) J2 rigidly connected to the housings J3 of ball bearings, seated on shafts 14, having eccentrically located pins 15; the housings / J are connected to each other by a strap 16 and are connected by means of tongs 17 with swing arms 18. On one pin of the lower shaft 14 an asterisk is mounted / I and on the other — gear 20, coupled with gear 21, sitting on the pin of the upper shaft 14; the sprocket 19 receives rotation via chain drives 22, 23 and 24 from the drive shaft 25.

The conveyor belt 5 of the pressing-drying unit moves intermittently and is provided with a strip 26, which serves to limit and compact the portion of sugar bars prepared for splitting. An apron 6, having a curved edge at the front, is attached by a hinge to the suspensions 27 of sliders 28 moving along the guide rods 29. In the front part of the apron 6, a stand 30 is rigidly fixed, having a roller 31 at the upper end moving along a profile bar 32 that is hingedly attached the lever 33 connected to the shaft 34 and the free end moves along the roller 55. The shaft 34 receives movement through the lever system and the roller 36 from the copier 37, from which the sliders 28 are kinematically connected through the slides 38 and the levers 39 connected to swivel shaft 40. The lamellar chains 8 and 9 are driven by shaft 41 from the drive of the machine.

The bars 3 of refined sugar with intermittent forward movement of the conveyor 5 are fed to the bar 26 and compacted by the movement of the belt of this conveyor. At the moment the conveyor 5 is stopped, the bars will be mixed in the direction perpendicular to it by apron 6 on table 7. The portions of the bars on table 7 are moved by the cross bar of chains 8 and 9 to the knives I and 2. At this time, the front part of the apron 6 rises, the apron moves to the initial position and after stopping the conveyor 5 is lowered with its front part, captures the next portion of the bars and, through the transition tray 42, delivers it to the table 7. Knives 1 and 2 (the trajectory of movement of which is shown in Fig. 6 with arrows C) split a portion of the sugar bars and on 4 pieces which are then bars 10 are reset with the section 7 to the receiving conveyor (not shown).

The puncher was tested at the Odessa refinery with positive results. The capacity of the machine for splitting 14 bars is 350 centners of crushed refined sugar per day, while conventional machines such as Schiebler when splitting 28 bars give for the same time 200 centners of crushed refined sugar.

The industrial value of this proposal has been confirmed by the Central Research Institute for Sugar Industry.
