Detailed Description

The technical scheme of the invention is further specifically described by the following embodiments and the accompanying drawings 1-2.

The utility model provides an auxiliary device that injection moulding machine used, is including connecting feeder hopper 2 of injection molding machine body 1, wherein is provided with the throat portion 3 of being connected with injection molding machine body 1 in feeder hopper 2 bottom, so through feeder hopper 2 and throat portion 3 with the leading-in injection molding machine body 1 of product in, and because 3 internal diameters in throat portion are less than 2 internal diameters of feeder hopper to this makes the long-time work of removing dust that stops of material ability in feeder hopper 2.

As shown in fig. 1, be provided with two rings of upper and lower dust removal pipe 4 on 2 inside walls of feeder hopper that lie in throat 3 top, wherein evenly be provided with induced draft hole 5 on the lower half lateral wall of dust removal pipe 4, and dust removal pipe 4 passes through 16 activity fixes on 2 inside walls of feeder hopper, and two sets of dust removal pipe 4 are connected with the separating mechanism 7 that lies in the 2 outsides of feeder hopper through exhaust column 6, the separating mechanism 7 of work passes through exhaust column 6 during the use, dust removal pipe 4 and 5 absorption of exhaust hole lie in impurity such as the diffuse dust in feeder hopper 2, thereby reach the mesh of getting rid of dust impurity in the material in the feeder hopper 2.

Because the hole 5 that induced drafts is located the lower half lateral wall of dust removal pipe 4, the material that leads to falling from the feeder hopper 2 top is difficult for dropping and blocks up it on hole 5 that induced drafts, and this has played positive effect to promoting the unblocked of hole 5 that induced drafts.

Wherein, in order to fully lift up the impurities such as dust in the material in the feed hopper 2 and draw out the impurities by the dust removing pipes 4, a sieve plate 8 positioned between two groups of dust removing pipes 4 is arranged in the feed hopper 2, a motor 12 is also arranged on the cover plate 10, wherein the motor 12 is provided with a rotating shaft 13 which sequentially passes through the cover plate 10, the circle center of the dust removing pipe 4, the sieve plate 8 and the necking part 3 and extends into the injection molding machine body 1, and the rotating shaft 13 positioned in the feed hopper 2 is provided with a horizontal stirring paddle 14, as shown in figure 1, a feed pipe 11 positioned right above the inner diameter of the dust removing pipe 4 is arranged at the left side of the cover plate 10, so that the dust removing pipes 4 can not influence the material falling from the feed pipe 11, and the working motor 12 drives the horizontal stirring paddle 14 to rotate through the rotating shaft 13 to stir the material positioned in the feed hopper 2 at the upper and lower sides of the sieve plate 8, wherein, in order to prevent the material in the throat 3 from blocking the material and leading the material in the feeding hopper 2 not to be easily led into the injection molding machine body 1 for processing, a spiral stirring paddle 15 is arranged on a rotating shaft 13 in the throat 3, so when a working motor 12 drives a horizontal stirring paddle 14 through the rotating shaft 13 to stir the material in the feeding hopper 2, the spiral stirring paddle 15 in the throat 3 is also driven to stir spirally downwards, at the moment, the rotating spiral stirring paddle 15 can forcibly lead the material in the feeding hopper 2 into the bottom end of the throat 3 and discharge the material, so as to discharge the material in the feeding hopper 2 through the throat 3 in a way of human intervention, and prevent the material from blocking the throat 3 so as to facilitate the discharge of the material, wherein, because the horizontal stirring paddle 14 for stirring the material in the feeding hopper 2 and the spiral stirring paddle 15 for forcing the material in the feeding hopper 2 to be discharged from the throat 3 are both driven by the same group of motor 12 and the rotating shaft 13, this not only reduces the requirements on the number of motors 12 and shafts 13, but also saves costs, and the reduction in the number of devices also facilitates maintenance.

As shown in fig. 1, a horizontal stirring paddle 14 positioned above the sieve plate 8 stirs the materials to uniformly drop through the sieve holes of the sieve plate 8, so that the materials can not fall in a larger line shape, and the impurities such as dust and the like in the falling materials screened by the sieve plate 8 are easier to diffuse in the feed hopper 2, thereby leading the dust removal pipe 4 to more effectively extract impurities in the materials, and the right side of the sieve plate 8 is provided with the material leakage port 9, when the materials are guided into the feed hopper 2 through the feed pipe 11, because the position of the feeding pipe 11 is opposite to that of the material leaking opening 9, the material directly falling from the feeding pipe 11 can not directly fall into the material leaking opening 9 and fall down, but is moved by the horizontal stirring paddle 14 and is screened by the sieve plate 8, and the materials which can not be screened by the sieve holes at the moment can fall from the position when passing through the material leakage port 9, so that the materials are prevented from being deposited in the feed hopper 2 at the top of the sieve plate 8 in a large scale.

In this embodiment, the separation mechanism 7 includes a separation tank 71, wherein a filter screen 72 located above the exhaust pipe 6 is disposed in the separation tank 71, an exhaust fan 73 is connected to the separation tank 71 located at the top of the filter screen 72 through a pipeline, and a support 17 for supporting the separation tank 71 is disposed at the top of the injection molding machine body 1. During operation air exhauster 73 will permeate impurity such as dust or the less volume material of feeder hopper 2 through knockout drum 71, exhaust column 6, dust removal pipe 4 and suction hole 5 and take out, get into the knockout drum 71 after impurity or the less volume material filters by filter screen 72 for the less volume material silts up in knockout drum 71 of filter screen 72 below, and the dust is then directly taken out, and people can open the discharging pipe of knockout drum 71 bottom at this moment and will filter the material recycle of gained small volume.

The use method of the invention comprises the following steps: the material is guided into the feed hopper 2 above the sieve plate 8 through the feed pipe 11, the motor 12 drives the rotating shaft 13 and the horizontal stirring paddle 14 to stir the material so that the material is uniformly scattered into the feed hopper 2 below the sieve plate 8 through the sieve holes, part of the material falls down when passing through the material leakage port 9, and impurities such as dust and the like mixed in the material are diffused in the feed hopper 2;

then the exhaust fan 73 pumps out impurities such as dust and the like or materials with smaller volume which are diffused in the feed hopper 2 through the separation tank 71, the exhaust pipe 6, the dust removal pipe 4 and the exhaust hole 5, when the impurities or the materials with smaller volume enter the separation tank 71, the impurities or the materials with smaller volume are filtered by the filter screen 72, so that the materials with smaller volume are deposited in the separation tank 71 below the filter screen 72, the dust is directly pumped out, and at the moment, people can open the discharge pipe at the bottom of the separation tank 71 to recycle the materials with small volume which are obtained by filtering;

when the motor 12 in operation further drives the horizontal stirring paddle 14 through the rotating shaft 13 to stir the material in the feeding hopper 2, the spiral stirring paddle 15 in the throat part 3 is also driven to stir spirally downwards, and at the moment, the material in the feeding hopper 2 is forced to be guided into the bottom end of the throat part 3 by the rotary spiral stirring paddle 15 and is discharged, so that the material is prevented from being deposited in the throat part 3.

The present invention has been described in detail, but the above description is only a preferred embodiment of the present invention, and is not to be construed as limiting the scope of the present invention. All equivalent changes and modifications made within the scope of the present invention shall fall within the scope of the present invention.
