Description

Technical Field

[0001] The present invention relates to the technical field of glass bead screening, in particular to an automatic screening and packaging device for glass beads used in highway tunnels. Background Art

[0002] Glass beads for highway tunnels are a special material designed specifically for the construction of highway tunnels and other transportation infrastructure. They are mainly used as reflective materials in road markings (paints), significantly improving the retroreflective performance of road markings. When a car is driving in a tunnel at night, the headlights shine on the road markings with glass beads, which can reflect the light back in parallel, allowing the driver to see the direction of travel clearly and improving nighttime driving safety. These glass beads are usually spherical or pancake-shaped particles with a diameter generally ranging from 200 microns to 1000 microns.

[0003] Application publication number CN115445932A discloses a glass bead isolation type dynamic screening device and screening method. Multiple screening boxes are staggered on both sides of the feed screening tube. Inside the screening box, there are provided a telescopic device, a rotating device connected to the output shaft of the telescopic device, and a screen cylinder connected to the output shaft of the rotating device. The screening box is equipped with a first material distribution component that is connected to the front cavity and a second material distribution component that is connected to the rear cavity. Cylinder assemblies located at the upper and lower sides of the screening box are installed on the outside of the feed screening tube. The present invention screens glass beads through the cooperation of the blowing mechanism and the screening box. When the screen cylinder is blocked, the screening box is isolated from the feed screening tube, and the remaining active large-particle glass beads in the front cavity are discharged and recovered. The screen cylinder is subjected to reverse airflow and pressure shock, thereby realizing the automatic screening of glass beads and the cleaning of blockages, and ensuring the efficiency of the glass bead screening process.

[0004] Existing road tunnels use drum screening machines for large-scale screening of glass beads. When the drum screening machine is screening the glass beads, the glass beads will frequently collide with each other during the screening process, generating large noise and vibration, which will affect the health of workers. At the same time, the collision of glass beads will increase the chance of damage. When the drum screening machine is screening, the glass beads may get stuck in the sieve holes, causing the screen to be blocked, affecting the screening effect and the normal operation of the equipment. Summary of the Invention

[0005] The object of the present invention is to provide an automatic screening and packaging device for glass beads for highway tunnels to solve the problems raised in the above background technology.

[0006] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: an automatic screening and packaging device for glass beads for highway tunnels, comprising a mounting mechanism, the mounting mechanism comprising a tank body, an air inlet pipe being provided on the tank body, and a screening assembly comprising a telescopic rod, the telescopic rod being fixed to the bottom of the tank body, a spring being sleeved on the telescopic rod, a mounting cylinder being fixed at the end of the telescopic rod, a mounting column being fixed above the mounting cylinder, a limit rod being slidingly provided on the mounting column, a spring being provided between the limit rod and the mounting column, a screening spiral tube being fixed on the mounting column, a guide spiral plate being fixed on the screening spiral tube, a screen plate being fixed inside the screening spiral tube, a plurality of discharge pipes being provided on the side of the screening spiral tube, a plurality of inclined baffles being provided inside the screening spiral tube, a discharge pipe being provided at the lower end of the screening spiral tube, two vibration motors being fixed below the screening spiral tube, a plurality of discharge mechanisms being fixed inside the tank body, the plurality of discharge mechanisms being all located below the corresponding discharge pipes, and a plurality of discharge mechanisms being provided at the bottom of the tank body.

[0007] Furthermore, the plurality of inclined baffles are made of rubber material.

[0008] An inlet funnel is arranged above the tank body, a fixing plate is fixed above the inlet funnel, the end of the limiting rod is fixed below the fixing plate, and a plurality of discharge holes are opened on the side of the tank body.

[0009] A communication port is provided on the discharge pipe, and a plurality of mutually staggered guide plates are provided inside the discharge pipe.

[0010] Furthermore, the guide plates are made of rubber.

[0011] The discharging mechanism comprises a conveyor belt, which is located inside the discharging hole, and a plurality of packaging bottles are placed above the conveyor belt.

[0012] The unloading mechanism includes a collecting box, which is fixed on the inner wall of the tank body. A cylinder is fixed below the collecting box, and an auger is rotatably arranged inside the cylinder. A conveying motor is fixed above the collecting box, and the output shaft of the conveying motor is connected to the auger through a coupling. A unloading port is opened below the cylinder.

[0013] Furthermore, the bottom of the collecting box is arranged at an angle, and a rubber buffer layer is laid on the bottom of the collecting box.

[0014] A backing plate is provided at the bottom of the screening spiral tube, and the air inlet pipe is located above the screening spiral tube.

[0015] Furthermore, the pad is made of rubber material.

[0016] An isolation spiral plate is fixed inside the screening spiral tube. The isolation spiral plate and the screen plate separate the inside of the screening spiral tube into an air inlet bin, a screening bin and a material drop bin. A number of air guide inclined slots are provided on the isolation spiral plate, and the air inlet pipe is connected to the air inlet bin.

[0017] A plurality of air guide plates are fixed below the sieve plate, and the air inlet pipe is connected to the air inlet bin.

[0018] Compared with the prior art, the present invention has the following beneficial effects:

[0019] The automatic screening and packaging device for glass beads for highway tunnels can make the glass beads spirally roll and fall by arranging screening spiral tubes, pads, isolation spiral plates and screen plates. During the rolling and falling process, the glass beads are screened to avoid frequent collisions of the glass beads during the screening process, reduce noise and vibration during screening, and avoid affecting the health of workers. A number of air guide chute are opened on the isolation spiral plate, and a number of air guide plates are fixed under the screen plate to continuously accelerate the falling speed of the glass beads, thereby accelerating the screening speed of the glass beads. After the glass beads are screened, the glass beads fall into the interior of the drop bin, and the air continuously accelerates the discharge speed of the glass beads, so that it can screen glass beads in large quantities.

[0020] By arranging a number of mutually staggered guide plates inside the discharge pipe, the falling glass beads can be resisted and guided, the height of the glass beads falling can be limited, and the probability of damage caused by collision when the glass beads fall can be reduced. At the same time, the air is discharged from the discharge pipe, which can speed up the discharge speed of the glass beads through the discharge pipe, reducing the probability of glass beads being damaged by collision while taking into account the discharge speed of the discharge pipe.

[0077] The discharge pipe 510 is provided with a communication port 516, and the interior of the discharge pipe 510 is provided with a plurality of interlaced guide plates 517;

[0078] It should be noted that the guide plates 517 are all made of rubber material. The guide plates 517 that are interlaced with each other can slow down the falling glass beads, prevent the glass beads from falling too fast, and avoid the chance of damage caused by the falling glass beads.

[0079] The discharge mechanism 3 includes a conveyor belt 302, which is located inside the discharge hole 104. A plurality of packaging bottles 301 are placed above the conveyor belt 302.

[0080] It should be noted that the packaging bottles 301 are located directly below the unloading mechanism 6 , and the conveyor belt 302 intermittently transports several packaging bottles 301 to directly below the unloading mechanism 6 . After the packaging bottles 301 are loaded with a certain amount of glass beads, the packaging bottles 301 are transported out of the tank body 103 .

[0081] The unloading mechanism 6 includes a collection box 601, which is fixed to the inner wall of the tank body 103. A cylinder 603 is fixed below the collection box 601. An auger 604 is rotatably provided inside the cylinder 603. A conveying motor 602 is fixed above the collection box 601. The output shaft of the conveying motor 602 is connected to the auger 604 via a coupling. A discharge port 605 is provided below the cylinder 603.

[0082] It should be noted that the bottom of the collecting box 601 is tilted, and a rubber buffer layer is laid on the bottom of the collecting box 601, which can cushion the falling glass beads and reduce the chance of glass beads being damaged by collision. The glass beads fall into the interior of the collecting box 601 from the discharge pipe 510, and the collecting box 601 guides the glass beads to the interior of the cylinder 603. The conveying motor 602 drives the auger 604 to rotate through the output shaft. The auger 604 conveys the glass beads in a quantitative manner and discharges the glass beads from the discharge port 605. The number of conveyed glass beads is controlled by controlling the speed of the auger 604 to achieve quantitative conveying.

[0083] A backing plate 512 is provided at the bottom of the screening spiral tube 511, and the air inlet pipe 2 is located above the screening spiral tube 511;

[0084] It should be noted that the pad 512 can cushion the glass beads that fall after screening, reducing the probability of collision damage when the glass beads fall, and at the same time, reducing the speed of the glass beads during screening.

[0085] An isolation spiral plate 515 is fixed inside the screening spiral tube 511. The isolation spiral plate 515 and the screen plate 513 separate the interior of the screening spiral tube 511 into an air inlet bin, a screening bin, and a material drop bin. A plurality of air guide chute 509 are provided on the isolation spiral plate 515. The air inlet pipe 2 is connected to the air inlet bin.

[0086] It should be noted that the air inlet pipe 2 blows air into the interior of the air inlet bin. When the air fills the interior of the air inlet bin, the air is blown from several air guide chute 509 to the glass beads on the screen plate 513, continuously accelerating the falling speed of the glass beads, thereby accelerating the screening speed of the glass beads. After the glass beads are screened, they fall into the interior of the drop bin. At the same time, the air is discharged from the discharge pipe 510, and at the same time, the discharge speed of the glass beads is accelerated.

[0087] Several air guide plates 514 are fixed below the sieve plate 513, and the air inlet pipe 2 is connected to the air inlet bin;

[0088] It should be noted that after the glass beads are screened, they fall into the interior of the drop bin. Several air guide plates 514 guide the screened glass beads, causing them to fall at an angle, thereby increasing the initial velocity of the glass beads when they fall. At the same time, several air guide plates 514 can also guide the air only twice, continuously blowing the inside of the drop bin, thereby continuously accelerating the movement speed of the glass beads on the pad 512, thereby making full use of the air and speeding up the screening speed.

[0089] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the invention, and that the scope of the invention is limited by the accompanying embodiments and their equivalents.
