Abstract
The invention relates to an air intake and exhaust device for a coating machine, which comprises an uptake ventilator (1) and a downcast ventilator (5). The uptake ventilator (1) and the downcast ventilator (5) are mounted on two sides of a coating drum (4) respectively. The air intake and exhaust device is characterized in that an air inlet (7) of the downcast ventilator (5) is arranged at the top of the downcast ventilator (5) and is opposite to the front of a middle line (6) of the drum, an air outlet (2) of the uptake ventilator (1) is arranged on the lower portion of the uptake ventilator (1) and is opposite to the rear of the middle line (6) of the drum, two air intake guide vanes are mounted under the air inlet (7) in the downcast ventilator (5) and respectively include an upper vane (8) and a lower vane (14), initial positions of the upper vane (8) and the lower vane (14) are perpendicular to a central line (16) of the coating drum (4), the bottom of the upper vane (8) is connected with the top of the lower vane (14) through a pin (15), and the upper vane (8) and the lower vane (14) can rotate around the pin (15) respectively. Compared with the prior art, the air intake and exhaust device has the advantages that air volume is distributed more evenly, tablets are not adhered, and a tablet bed is evenly dried.
Description
Technical field
The present invention is that a kind of coating machine advances air exhausting device, belongs to the technical field of structures of product, is used for pharmaceutical machine equipment.
Background technology
Like Fig. 1, shown in 2, present domestic coating machine advances air exhausting device and generally adopts the air draft of rear side air intake rear side, the upside air draft of upside air intake or the one-sided air draft of single admission.During the upside air intake, the blast pipe centered, and do not design the air intake deflector in the air inlet.The operation principle of coating machine coating is: coating cylinder 4 drives the flip-flop movement that the interior tablet of cylinder is done continuous complicacy by the motor-driven rotation, and the spray guns in the coating cylinder 4 spray coating solution to tablet simultaneously.Air through heating gets into coating cylinders 4 from the air inlet of air intake tube 57, and the exhaust outlet through air draft tube 12 takes air away, and sheet bed 3 is dried.
For high capacity coating machine, because coating drum length size is big, so the sheet bed distributes wide; Existing coating machine advances that the air inlet of air exhausting device is less relatively, and the air feed position is concentrated relatively, causes different sheet beds zone air quantity to distribute uneven; Rate of drying difference is big, influences the tablet coating quality.
Summary of the invention
The shortcoming that the present invention exists to above-mentioned prior art just and design and provide a kind of coating machine to advance air exhausting device; Its objective is when solving the long cylinder coating of high capacity machine sheet bed than broad; Have each regional air quantity problem of uneven distribution of into air draft mode sheet bed now, reach the effect that the sheet bed is evenly dried.
The objective of the invention is to realize through following technical measures:
This kind coating machine advances air exhausting device, comprises air draft tube (1) and air intake tube (5), and air draft tube (1) and air intake tube (5) are installed in the both sides of coating cylinder (4) respectively, it is characterized in that:
The air inlet (7) of this device air intake tube (5) is opened at the top of air intake tube (5), and the position is with respect to the front side of cylinder intermediate line (6), and air inlet (7) is definite by following formula with the distance L of cylinder intermediate line (6),
L＝KD
In the formula: D is the length of coating machine cylinder, and the span of K is 0.1～0.2;
The exhaust outlet (2) of this device air draft tube (1) is opened in the bottom of air draft tube (1), and the position is with respect to the rear side of cylinder intermediate line (6);
Two air intake guide vanes are installed in air intake tube (5), under the air inlet (7); Be respectively blade (8) and lower blade (14); The initial position of blade (8) and lower blade (14) is perpendicular to the centrage (16) of coating cylinder (4); The top of the bottom of blade (8) and lower blade (14) is connected through bearing pin (15), and blade (8) and lower blade (14) can rotate around bearing pin (15) respectively.
Technical scheme of the present invention is passed through advances, air draft adopts front upper side to advance back downside row mode, has improved the uniformity of air intake on the sheet bed, in addition; Through the setting of two air intake guide vanes, can realize the profile adjustment of intake, avoided different coating capacity; The problem that needs the different coating machine inlet boxes of design; And simple in structure, reliable, mounting or dismounting are convenient.

The specific embodiment
Below will combine accompanying drawing and embodiment that apparatus of the present invention are done to detail further:
A kind of coating machine advances air exhausting device, comprises air draft tube 1 and air intake tube 5, and air draft tube 1 and air intake tube 5 are installed in the both sides of coating cylinder 4 respectively, it is characterized in that:
The air inlet 7 of this device air intake tube 5 is opened the top at air intake tube 5; The position is with respect to the front side of cylinder intermediate line 6; Air inlet 7 has tangible front side to layout with respect to the cylinder intermediate line 6 of coating cylinder 4, and air inlet 7 is confirmed by following formula with the distance L of cylinder intermediate line 6
L＝KD
In the formula: D is the length of coating machine cylinder, and the span of K is 0.1～0.2;
The exhaust outlet 2 of this device air draft tube 1 is opened in the bottom of air draft tube 1, and the position is with respect to the rear side of cylinder intermediate line 6;
Two air intake guide vanes are installed in air intake tube 5, under the air inlet 7; Be respectively blade 8 and lower blade 14; Pole 10 is installed perpendicular to the centrage 16 of coating cylinder 4 in the initial installation site of blade 8 and lower blade 14 on the sidewall of air intake tube 5, pole 10 ends are welded with axle sleeve 13; Axle sleeve 13 links to each other through bearing pin 15 with lower blade 14 with blade 8, and blade 8 can rotate around bearing pin 15 respectively with lower blade 14.The end that 9, two adjusting screw(rod)s 9 of two adjusting screw(rod)s are set in the upper and lower position of pole 10 is hinged with blade 8 and lower blade 14 respectively through thread bush 12, and the sidewall that the other end of two adjusting screw(rod)s 9 passes air intake tube 5 is connected with adjusting nut 11.Through rotation adjusting nut 4, change adjusting screw(rod) 9 thread segments and screw in thread bush 12 length, the pendulum angle of control blade 8 and lower blade 14.Realize regulating and distributing with this to the air intake air quantity.
