The present invention relates to low specific gravity fiber used as a mixture recipe of mortar used in various industrial fields, and more particularly, to enable the quantitative supply of low specific gravity fiber, which is one of the mixing recipes constituting mortar It relates to a low specific gravity fiber metered supply device.

In general, fibers with low specific gravity are used as one of the raw materials of mortar mixing recipe, which is used as a raw material for a product to increase the binding of mortar.

While the low specific gravity fiber has a low specific gravity and high binding property, it is often mixed and used to lighten the product. Due to the low specific gravity, it was difficult to supply a quantitative discharge when adding a mixture of a mortar mixing recipe.

In order to solve the above difficulties, a low specific gravity quantitative supply device is as shown in FIGS. 1 to 2.

As can be seen from FIGS. 1 and 2, the conventional low specific gravity fiber supply device 10 is narrowed from the middle of the inside 14 to the bottom to regulate the falling speed of fibers forming a funnel. A pipe 13 is provided, and a maintenance gate is formed at the bottom of the side wall so that it can be used when a discharge error occurs due to low specific gravity fibers or when internal maintenance is required. The maintenance gate is opened and closed A fiber storage box 11 in which a hinged maintenance door 15 is installed and a discharge passage 16 through which low specific gravity fibers are discharged is formed on the bottom surface adjacent to the side wall line;

A key is fixedly installed to the rotation shaft 17b of the drive motor 17a of the drive unit 17 penetrating the center of the bottom plate 11a of the fiber storage box 11, and through the fiber drop speed regulating pipe 13 Fluffellers 18 and 18a are formed in all directions to scatter and release the falling low-specific gravity fibers and simultaneously transport them to the discharge path 16, and the length of the feeding blades 18 and 18a is A low specific gravity fiber supply unit 20 having a short length on one side and a long length on the other side based on a cross;

A drive motor (17a) for rotating the feeding blades (18) (18a) constituting the low specific gravity fiber supply unit (20) attaches a fixing bracket (17c) to the lower surface of the bottom plate (11a) of the fiber storage box (11). Consisting of a drive unit 17 fixedly installed as a medium and having a shaft hole 18b formed at the center of the feeding blades 18 and 18a key assembled to a rotating shaft 17b located through the bottom plate 11a. will be.

In the conventional low specific gravity fiber supply device 10 configured as described above, the low specific gravity fiber packed in a ton bag is transported and stored.

When the low specific gravity fibers stored as described above are to be used as a mixed recipe for mortar, the driving motor 17a constituting the driving unit 17 is driven.

As described above, as the drive motor 17a of the drive unit 17 is driven, the feeding blades 18 and 18a of the low specific gravity fiber supply unit 20 in which the shaft hole 18b is key-assembled to the rotation shaft 17b rotate. It does.

In the conventional low specific gravity fiber quantitative supply device 10 for discharging and supplying the above and low specific gravity fibers, the low specific gravity fibers are simply loaded and transported on the feeding blades 18 and 18a constituting the fiber supply unit 20 by a falling load, Since it loses, it not only has a problem of not being able to stably discharge and supply when supplying mortar mixed recipe additives, but also the feeding blades 18 constituting the fiber supply unit 20 (18a), which is the center of the rotating shaft (17b) It has the disadvantage that the low specific gravity fiber falling toward the side does not spread in all directions and clumps occur, causing a problem that the low specific gravity fiber is not supplied to the mortar mixing recipe. There is a disadvantage in that the low specific gravity fiber is stuck between the bottom plate 11a of the fiber storage box 11 and becomes hard and cannot be moved and discharged, so that the mixing ratio of the low specific gravity fiber cannot be satisfied in the mortar mixing recipe.

A part is formed so that the shaft hole of the feeding blade is connected to the rotational axis of the drive unit into which the shaft hole is inserted, and at the same time, a rubber scraper that pushes and moves the low specific gravity fiber is installed on the bottom of each feeding blade. At the same time, air is sprayed from top to bottom so that the low specific gravity fibers can sink stably to the bottom plate of the fiber storage box, and the air is blown at an oblique angle from the air nozzle installed on the side wall of the fiber storage box. As it is sprayed in the same direction as the direction in which the feeding blade of the low specific gravity fiber supply unit rotates, the low specific gravity fiber is stably released with respect to the feeding blade, which is the low specific gravity fiber supply unit, so that the low specific gravity fiber is released into the discharge path. As the specific gravity fiber can be discharged in a constant quantity, it is possible to add low specific gravity fiber in a quantitative way when preparing the mortar mixture recipe, so that it is possible to produce a high-quality mortar mixture recipe without mixing defects of the mortar mixture recipe, and products using this It is not only possible to improve the quality of the fiber, but also to provide a low specific gravity fiber quantitative supply device that solves the defects of the mixed recipe caused by the measurement error when producing the mortar mixed recipe as it is possible to quantitatively measure the low specific gravity fiber without measurement errors. .
