Description

Изобретение относитс к дозированию материалов и, в частности, к уст ройствам дл объемного дозировани и ориентированной раздачи жидкостей, например герметика.The invention relates to the dosing of materials and, in particular, to devices for volumetric dosing and oriented distribution of liquids, for example, a sealant.

Известен объемный дозатор жидкости , содержащий корпус, установленный . в н-ем дозирующий барабан с капилл рными мерными каналами, привод враще .ни барабана и источник давлени транспортируквдего газа fl}.Known volumetric fluid dispenser, comprising a housing installed. In it, there is a metering drum with capillary measuring channels, a drive for rotating the drum and a source of pressure for the gas fl}.

Однако указанный дозатор имеет сложную конструкцию, а объемы устанавливаемых в нем доз ограничены.However, the specified dispenser has a complex structure, and the volumes of the doses installed in it are limited.

Наиболее близким по технической сущности к изобретению вл етс устройство дл дозированной раздачи жидкого материала, содержащее корпус с камерой, в которой установлен барабан с мерными каналами по окружности, а такж.е канашл подвода и отвода жидкости и канал подачи сжатого, воздуха, расположенный соосно с каналом отвода жидкости 2}.The closest in technical essence to the invention is a device for dispensing a liquid material, comprising a housing with a chamber in which a drum with measured channels is installed around the circumference, as well as a canal of supply and discharge of liquid and a compressed air supply channel located coaxially with channel drain 2}.

Недостатками указанного устройства также вл ютс сложность конструкций и ограниченность объема дозы жидкости , обусловленна тем, что в качестве Мерных каналов испсшьзуютс капилл ры.The disadvantages of this device are also the complexity of the structures and the limited volume of the dose of liquid, due to the fact that capillaries are used as Measuring channels.

Цель изобретени - повышение точности дозировани .The purpose of the invention is to improve the accuracy of dosing.

Указанна цель достигаетс тем, что в устройстве дл дозиро ванной раздачи жидкого материала, содержащем корпус с камерой, в которой установлен барабан с мерными каналами по ОКР1ШНОСТИ, а также каналы подвода и отвода жидкости и канал пода10 чи сжатого воздуха, расположенный соосно с каналом отвода жидкости, камера вьтолнена в виде полуцилиндра , поверхность которого сопр жена с двум плоскост ми, а мерные ка15 налы - открытыми в виде пазов, расположенных по образующей барабана, при этом барабан своей боковой поверхностью прилегает к цилиндрической поверхности камеры, выполненной This goal is achieved by the fact that in a device for dispensing a liquid material, comprising a housing with a chamber in which a drum with measured channels is installed according to the CIRCULATION, as well as channels for supplying and discharging liquid and a channel for supplying compressed air, located The chamber is made in the form of a half-cylinder, whose surface is mated with two planes, and the measuring frames are open in the form of grooves located along the generator of the drum, while the drum with its side surface is adjacent to the cylinders. ndricheskoy chamber surface formed

20 того же радиуса, что и барабан, а канал подвода .жидкости соединен с частью камеры между ее противоположной стенкой и барабаном.20 of the same radius as the drum, and the liquid inlet channel is connected to the part of the chamber between its opposite wall and the drum.

Claims

30 kryiikami 2 and 3. In the lid 2 there is a channel for supplying compressed air with a nozzle 4, which provides a purge of a measuring liquid column into the product. The housing 1 through the top cover 2 is connected by a nozzle 5 with a container b containing the liquid to be dosed, and has a chamber B made in the form of a semi-cylinder j interfaced with two planes / and providing the greatest contact with the metering drum 7 made in the form of a cylinder with eight slots according to his form. The drum 7 is made of fluoroplast to reduce adhesion with liquid and rigidly mounted on shaft 8, on the lower free end of which an orientator 9 is fixed, made in the form of an eight-tooth sprocket, in contact with the filled products 10 installed in the cassette 11 A device for dispensing a liquid operates as follows. The articles 10, for example tubular electric heaters installed in the cassette 11, form a rail with a legal step. When the cassette 11 is moved, the orientator 9 rolls around the rail formed by the products 10, which moves progressively and through the shaft causes the rotation of the dosing bar 7, the measuring channels of which, moving in the bore volume of chamber B, are filled with metered liquid. A liquid table B in the measuring chamber G when exiting chamber B is locked between housing 1 and covers 2 and 3 and transferred with further rotation of the drum 7 to the nozzle 4, where it is passed by the transporting gas to the product 10. Increasing the pressure of the transporting gas and the speed of movement of the cartridge 11, it is possible to adjust the performance of the device. The proposed device provides a strictly oriented distribution of the liquid in the product, and is also characterized by simplicity of design. Apparatus of the Invention A device for dispensing a liquid material, comprising a housing with a chamber in which a drum with circumferential channels is installed, as well as fluid supply and discharge channels and a compressed air supply channel located coaxially with the fluid discharge channel, characterized by. To increase accuracy, the chamber is made in the form of a half cylinder, the surface of which is mated to planes, and the measuring channels are open in the form of grooves located along the generator of the drum, while the drum with its side surface is adjacent to the cylindrical surface of the chamber, made the same radius as the drum, and the channel for supplying the liquid is connected to a part of the chamber to the melody by its opposite wall and drum.
