Install vibrating motor on the base, vibrating motor is used for driving sieve case 2 vibration. Hopper 3 is installed at 2 tops of sieve case, and hopper 3 and the equal slope setting of sieve case 2, the vertical feeding section of thick bamboo 1 of installing in high-end top of hopper 3, and the discharge gate has been seted up to the low side of sieve case 2, and the discharge gate intercommunication has a feed cylinder. A plurality of sieve meshes have been seted up to 3 bottoms of hopper, and the sieve mesh includes first sieve mesh 4 and second sieve mesh 8, and the aperture of first sieve mesh 4 is less than the aperture of second sieve mesh 8. The first screen hole 4 is used for screening powder and impurities in the plastic particles, and the second screen hole 8 is used for screening the finished plastic particles. The screen box 2 is respectively provided with a recovery cavity for containing the different screened materials.
All the baffles 5 in the free state are disposed obliquely downward, i.e., the state shown in fig. 1. A driving mechanism for driving the baffle 5 to swing in the longitudinal direction of the hopper 3 is installed in the side wall of the hopper 3. As can be known from fig. 2, the driving mechanism includes a driving rod 9 slidably connected in the sidewall of the hopper 3, the driving rod 9 is disposed along the length direction of the hopper 3, the driving rod 9 is connected to a power source for driving the driving rod to slide, in this embodiment, the power source is a cylinder, and the cylinder is mountable on the base. The driving rod 9 is connected with the baffle 5 through a pull rope, specifically, bolts 11 can be respectively installed on the end part of the baffle 5 and the driving rod 9, two ends of the pull rope are tied on the bolts 11, and a movable space is provided for the baffle 5 through the pull rope.
As shown in fig. 2 and 3, a supporting table 10 is installed in the sidewall of the hopper 3, a supporting curved surface 12 with a higher end and a lower end is formed at the top of the supporting table 10, the lower end of the supporting curved surface 12 is close to the higher end of the hopper 3, and the end of the baffle 5 is slidably connected to the supporting curved surface 12. Specifically, the end of the baffle 5 is connected with a slide block, a dovetail groove is formed in the supporting curved surface 12 along the length direction of the supporting curved surface, and the slide block is connected in the dovetail groove in a sliding mode.
The specific implementation process is as follows:
in actual use, the feeding cylinder 1 can be communicated with an extruder, and extruded plastic particles directly enter the hopper 3 from the feeding cylinder 1 for screening. Start vibrating motor and cylinder, vibrating motor drives the vibration of sieve case 2 to drive the vibration of hopper 3, plastic granules removes to the low side from the high-end of hopper 3 under the effect of the vibration of hopper 3, and the in-process of removal realizes the screening through the sieve mesh. Specifically, dust, impurities and plastic particles with a smaller particle size drop through the first sieve opening 4 into a recycling cavity in the sieve box 2. The plastic granules which can not pass through the first sieve holes 4 continue to move downwards, and when the plastic granules move to the second sieve holes 8, the finished plastic granules pass through the second sieve holes 8 and fall into the other recycling cavity in the sieve box 2. The plastic granules which cannot pass through the second sieve openings 8 then remain in the hopper 3, whereby a sifting of the plastic granules is achieved.
In the initial state, the baffle 5 is in the state shown in fig. 1, and most plastic particles cannot move directly from the high end to the low end of the hopper 3 due to the limitation of the baffle 5, but move downwards in the hopper 3 in a wave-shaped path. Therefore, the retention time of the plastic particles in the hopper 3 is increased, namely, the screening time is increased, the plastic particles can be screened more thoroughly, and the screening effect is improved.
In the screening process, the driving rod 9 pushed by the air cylinder gap slides towards the lower end of the hopper 3, and the driving rod 9 drives one end, located in the side wall of the hopper 3, of the baffle plate 5 to swing towards the lower end of the hopper 3, so that the part, located in the hopper 3, of the baffle plate 5 swings towards the high end of the hopper 3. Thereby utilize baffle 5 to promote plastic granules towards the high-end of hopper 3 for plastic granules goes back to carry out the secondary screening, has further improved the screening effect.
In the initial state, the baffle 5 is in the state shown in fig. 1, and one end of the baffle 5 located in the side wall of the hopper 3 is located at the lower end of the curved support surface 12. When baffle 5 is located the one end swing of hopper 3 high-end towards hopper 3 in the hopper, the one end that baffle 5 is located the hopper 3 lateral wall then can slide to high-end from the low end that supports curved surface 12, and the one end that baffle 5 is located hopper 3 will be lifted up promptly, and then the part that baffle 5 is located hopper 3 will be pushed down, reduces the distance between baffle 5 and the hopper 3 bottom from this, can push back more plastic granules.
If the part of the baffle 5 located in the hopper 3 is swung back in a compacted state towards the lower end of the hopper 3 to the state of fig. 1, the baffle 5 will push the plastic particles downwards again, which will affect the sieving of the plastic particles. Therefore, in the embodiment, the supporting table 10 is provided to support the baffle 5, when the portion of the baffle 5 located in the hopper 3 swings towards the lower end of the hopper 3, the end of the baffle 5 located in the sidewall of the hopper 3 slides from the high end of the supporting curved surface 12 to the lower end, so that the portion of the baffle 5 located in the hopper 3 is lifted, the distance between the baffle 5 and the bottom of the hopper 3 is increased, and the situation that the baffle 5 pushes the plastic particles downwards can be reduced. Install the cushion 6 in bar hole 7, can utilize the deformation of cushion 6 self to provide the space of activity for baffle 5 swing and lift on and push down.
According to the invention, the baffle 5 guides the plastic particles to move along the wave-shaped route, so that the retention time of the plastic particles in the hopper 3 is increased, the plastic particles are screened more thoroughly, and the screening effect is improved. In addition, swing through drive baffle 5 and push back plastic granules for plastic granules carries out the secondary screening, has further improved the screening effect.
Example two
The difference between this embodiment and the first embodiment lies in that baffle 5 bottom has glued a plurality of brush strips, and when baffle 5 swung towards the high-end of hopper 3, the bottom of hopper 3 can be cleaned to the brush strip to alleviate the condition of sieve mesh jam.
EXAMPLE III
As shown in fig. 4, the present embodiment is different from the first embodiment in that a balance bar 13 is installed on the hopper 3, the balance bar 13 is disposed across the hopper 3, the wire is sleeved on the left end of the balance bar 13, and the wire is welded on the screen box 2. The right end of the balance bar 13 is fixed on the hopper 3 through a lock catch. When the automatic plastic particle spraying machine is used, the balance rod 13 is fastened through the lock catch and is tightly pressed on the hopper 3, so that the vibration amplitude of the hopper 3 can be reduced, and plastic particles in the hopper 3 are prevented from splashing due to overlarge vibration amplitude.
The foregoing is merely an example of the present invention and common general knowledge of known specific structures and features of the embodiments is not described herein in any greater detail. It should be noted that, for those skilled in the art, without departing from the structure of the present invention, several changes and modifications can be made, which should also be regarded as the protection scope of the present invention, and these will not affect the effect of the implementation of the present invention and the practicability of the patent.
