Description

  The present invention relates to a feeder that feeds waste paper, waste plastic, and other supplies discharged from a hopper while keeping them from getting tangled.

  Conventionally, Patent Document 1 discloses a feeder that feeds a supply discharged from a hopper while keeping it from getting tangled. This technology detects an increase in load torque due to entanglement with the scraper plate from the motor current value of the supply panel, and when the load torque exceeds a certain value, the supply panel is automatically reversed or forward and reverse at regular time intervals. Thus, the entangled lump-like material is separated from the slide plate so that overload can be prevented.

  By the way, in the above technique, there is a problem that the supply is temporarily interrupted when the supply panel is reversed, the frequency of reverse rotation increases depending on the type and characteristics of the supply, and the application is limited such as the efficiency of supply deteriorates. there were.

  On the other hand, Patent Document 2 discloses a technique for preventing supply from being entangled. This technology is characterized in that a cylindrical body having protrusions on the outer periphery thereof is rotatably mounted directly below the scraping plate, and the supply material entangled with the scraping plate is wiped off by the protrusions by the rotation of the cylindrical body. .

However, in the above technique, even if a small amount of string-like material of 5 cm or more is mixed in the supply, it wraps around the cylindrical body, and once it is wound, it is difficult to come off even if it is reversed. As a result, the pay-off function is lost and not only the supply is interrupted, but also overload is promoted to cause damage to the apparatus, and the apparatus is expensive.

  The problem to be solved by the present invention is to solve these problems in the past, and to reduce the cost so that the supply to be entangled with the scraping plate can be supplied without interruption without being interrupted. It is to provide a material supply machine that is easily entangled.

The configuration of the present invention that solves this problem is as follows.
1) An intake port communicating with the hopper discharge port is opened on the upper surface of the cylindrical casing, a discharge port is opened on the lower surface of the casing, and a predetermined amount of supply taken from the intake port is accommodated at the bottom of the casing. In a quantitative feeder equipped with a feed plate provided with a stirring blade for rotating the inside of the casing to the discharge port, and a clip plate for cutting off the feed fed above the discharge port in the casing, An easily entangled substance characterized in that the stirring blade is attached to the supply board so as to pass directly under the scraping plate, and the supply material does not get entangled with the scraping plate due to the intersection of the sliding blade and the stirring blade. In the feeding machine.

  According to the present invention, the supply material entangled with the cutting plate due to the intersection of the cutting plate and the rotating stirring blade is peeled off with low resistance, and can be supplied smoothly and efficiently without interrupting the supply such as reverse rotation. . Further, since it is not necessary to separately install a dropping device such as a cylindrical body as in the prior art, the device is simple and low-cost.

  The interval between the sliding plate of the present invention and the stirring blade passing directly below it is practically in the range of 10 to 30 mm, but is determined according to the particle size of the feed. Embodiments of the present invention will be specifically described below with reference to the drawings.

  FIG. 1 is a plan view of the feeder of the embodiment, FIG. 2 is a longitudinal sectional view of the feeder of the embodiment, and FIG. 3 is an explanatory view showing the removal of the tangled lump of the embodiment. In the figure, 1 is a hopper, 1a is a discharge port, 2 is a feeder, 3 is a casing, 3a is an intake port, 3b is a discharge port, 3c is a forwarding space, 3d is an inspection port, 4 is a supply panel, 4a is a blade Reference numeral 4b denotes a cone, 5 denotes a sliding plate, 6 denotes a stirring blade, 7 denotes a motor, 10 denotes a supply, and 10a denotes a lump.

  As shown in FIGS. 1 and 2, the feeder 2 of the present embodiment has a casing 3 that is entirely cylindrical, and has an intake port 3 a having the same diameter as the discharge port 1 a of the hopper 1 on the upper surface and a discharge port 3 b on the outer periphery of the lower surface. Opening, the bottom surface 3e is formed by raising the inner bottom surface of the casing 3 into a cylindrical shape, and eight V-shaped blades 4a project from the outer periphery of the ring 4c, and the cone 4b is attached to the upper surface. Is attached so as to cover the bottom plate 3e, and the inner surface and the bottom surface of the casing 3 form a feeding space 3c for the supply 10.

  An arc-shaped scraping plate 5 is mounted horizontally on the inner wall of the casing 3 above the discharge port 3b, and a V-shaped stirring blade 6 is provided on the upper surface of the ring 4c of the supply board 4. Four bodies protrude from the lower surface of the sliding plate 5 at a height of 10 mm.

  In the present embodiment, the supply 10 discharged from the discharge port 1a of the hopper 1 is stirred by the stirring blade 6 to prevent the bridge, and is guided to the forwarding space 3c in the casing 3 by the cone 4b. The accommodated supply 10 is forwarded through the casing 3 to the discharge port 3b by the blades 4a, cut to a predetermined amount by the slide plate 5, and supplied to the outside from the discharge port 3b.

  Here, when the supply 10 has high binding properties such as waste paper, waste plastic, biomass, etc., a lump 10a of the supply 10 is formed at the end of the sliding plate 5 as shown in FIG. May become entangled and stable supply may not be possible.

  However, in this embodiment, since the stirring blade 6 is provided at a height that passes directly below the scraping plate 5, as shown in FIG. 3 (b), the lump 10a with the stirring blade 6 entangled is moved downward. It is dropped to the discharge port 3b together with the flow of the supply 10 which is separated from the plate end of the scraping plate 5 while being pulled and forwarded.

  Accordingly, since the supply 10 above the lump 10a entangled with the scraping plate 5 is not pulled in the rotation direction of the supply board 4, the stirring blade 6 easily lowers the lump 10a with low resistance. Although it has a simple structure, the supply 10 is reliably prevented from being entangled without load and can be supplied stably.

  FIG. 4 shows another example of the feeder according to the embodiment. FIG. 4 is a longitudinal sectional view of another example of the feeder. In the figure, 8 is a sport. As shown in FIG. 4, in another example of the feeder 2 of the embodiment, a cylindrical sport 8 having a diameter substantially the same as that of the ring 4 c is attached to the casing 3 so as to be movable up and down.

  When the intake port 3a of the feeder 2 is substantially the same diameter as the ring 4c of the feeder panel 4, if the stirring blade 6 is passed only below the scraping plate 5, the upper side of the scraping plate 5 becomes dead stock, and the supply Depending on the physical properties and shape of 10 and the size of the hopper 1, a bridge may occur in the hopper 1 starting from the dead portion.

  However, in another example of the embodiment, by providing a sport 8 having a diameter corresponding to the ring 4 c of the supply board 4, the dead portion and the supply 10 in the hopper 1 are blocked by raising and lowering the sport 8 so that the bridge is completely formed. Prevention and stable supply becomes possible. Other reference numerals and configurations are the same as those in the embodiment.

  The feeder of the present invention can be preferably used for supplying waste paper, waste plastic, and biomass.

It is a top view of the feeder of an Example. It is a longitudinal cross-sectional view of the supply machine of an Example. It is explanatory drawing which shows the exclusion of the entangled lump of an Example. It is a longitudinal cross-sectional view of the supply machine of the other example of an Example.
