Description

Technical Field

[0001] The present invention relates to the technical field of glass bead screening, and specifically provides 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 specifically designed for the construction of transportation infrastructure such as highway tunnels. They are mainly used as reflective materials in road markings (paints), significantly improving the retroreflective performance of road markings. When a vehicle travels at night in a tunnel, the headlights shine on the road markings with glass microspheres, and the light of the headlights can be reflected back parallel, enabling the driver to clearly see the forward direction and improving the safety of night driving. These glass beads are usually spherical or disc-shaped particles, and their diameter generally ranges from 200 microns to 1000 microns.

[0003] A glass microsphere isolation type dynamic screening device and screening method with the application publication number CN115445932A. A plurality of screening boxes are staggered on both sides of the feeding and screening pipe. Inside the screening box, there is 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 configured with a first material distribution component in communication and cooperation with the front cavity and a second material distribution component in communication and cooperation with the rear cavity. A cylinder assembly is installed outside the feeding and screening pipe at positions above and below the screening box. The present invention screens glass microspheres through the cooperation of a blowing mechanism and the screening box. When the screen cylinder is blocked, the screening box is isolated from the feeding and screening pipe to discharge and recycle the remaining large-particle glass microspheres in the front cavity, and a reverse airflow pressure impact is applied to the screen cylinder, realizing automatic screening and blockage cleaning of glass microspheres and ensuring the efficiency of the glass microsphere screening process.

[0004] When the existing drum-type screening machine is used for large-batch screening of glass beads for highway tunnels, the glass beads will collide with each other frequently during the screening process, generating relatively large noise and vibration, which has an impact on the health of the staff. At the same time, the colliding glass beads will increase the probability of damage. When the drum-type screening machine is screening, the glass beads may get stuck in the sieve holes, resulting in sieve mesh blockage, affecting the screening effect and the normal operation of the equipment. Summary of the Invention

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

[0006] To achieve the above object, the present invention provides the following technical solution: An automatic screening and packaging device for glass beads used in highway tunnels, including an installation mechanism. The installation mechanism includes a tank body, and an air inlet pipe is provided on the tank body. It also includes a screening component. The screening component includes a telescopic rod fixed at the bottom of the tank body. A second spring is sleeved on the telescopic rod. An installation cylinder is fixed at the end of the telescopic rod. An installation column is fixed above the installation cylinder. A limiting rod is slidably arranged on the installation column. A first spring is arranged between the limiting rod and the installation column. A screening spiral pipe is fixed on the installation column. A guiding spiral plate is fixed on the screening spiral pipe. A sieve plate is fixed inside the screening spiral pipe. A number of discharge pipes are arranged on the side of the screening spiral pipe. A number of inclined baffles are arranged inside the screening spiral pipe. A discharge pipe is arranged at the lower end of the screening spiral pipe. Two vibration motors are fixed below the screening spiral pipe. A number of blanking mechanisms are fixed inside the tank body. All the blanking mechanisms are located below the corresponding discharge pipes. A number of discharge mechanisms are arranged at the bottom of the tank body.

[0007] Further, all the 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. A number of discharge holes are formed on the side of the tank body.

[0009] A communication port is formed on the discharge pipe. A number of mutually intersecting guide plates are arranged inside the discharge pipe.

[0010] Further, the guide plates are all made of rubber material.

[0011] The discharge mechanism includes a conveyor belt located inside the discharge hole. A number of packaging bottles are placed above the conveyor belt.

[0012] The blanking mechanism includes a collection box fixed on the inner wall of the tank body. A cylinder is fixed below the collection box. An auger is rotatably arranged inside the cylinder. A conveyor motor is fixed above the collection box. The output shaft of the conveyor motor is connected to the auger through a coupling. A blanking port is formed below the cylinder.

[0013] Further, the bottom of the collection box is inclined, and a rubber buffer layer is laid on the bottom of the collection box.

[0014] A cushion plate is arranged at the bottom of the screening spiral pipe. The air inlet pipe is located above the screening spiral pipe.

[0015] Further, the cushion plate is made of rubber material.

[0016] An isolation spiral plate is fixed inside the screening spiral tube. The isolation spiral plate and the sieve plate divide the interior of the screening spiral tube into an air inlet chamber, a screening chamber, and a blanking chamber. A number of air guiding inclined grooves are formed on the isolation spiral plate, and the air inlet pipe is communicated with the air inlet chamber.

[0017] A number of air guiding plates are fixed below the sieve plate, and the air inlet pipe is communicated with the air inlet chamber.

[0018] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0019] In the automatic screening and packaging device for glass beads used in highway tunnels, by arranging a screening spiral tube, a backing plate, an isolation spiral plate, and a sieve plate, the glass beads can roll and fall spirally. During the rolling and falling process, the glass beads are screened, avoiding frequent collisions of the glass beads during the screening process, reducing the noise and vibration during screening, and avoiding affecting the health of the staff. A number of air guiding inclined grooves are formed on the isolation spiral plate, and a number of air guiding plates are fixed below the sieve plate, which can 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 blanking chamber, and the air continuously accelerates the discharging speed of the glass beads, enabling large-batch screening of the glass beads.

[0020] By arranging a number of mutually staggered guide plates inside the discharge pipe, the falling glass beads can be resisted and guided, restricting the falling height of the glass beads, reducing the probability of damage caused by collisions when the glass beads fall. At the same time, the air is discharged from the discharge pipe, which can accelerate the discharging speed of the glass beads through the discharge pipe, not only reducing the probability of damage to the glass beads by collisions but also taking into account the discharging speed of the discharge pipe.

[0035] It should be noted that the upper part of the screening spiral pipe 511 is open, which is convenient for glass beads to fall onto the sieve plate 513. A number of screening holes are opened on the sieve plate 513. The inclined baffle is made of rubber material, which can buffer the falling glass beads and reduce the probability of glass beads being damaged by collision. The glass beads fall onto the sieve plate 513 inside the screening spiral pipe 511 to screen the glass beads. The vibration motor 505 drives the screening spiral pipe 511 to vibrate, accelerating the screening speed of the glass beads and reducing the probability of glass beads getting stuck on the sieve plate 513. At the same time, the air inlet pipe 2 blows the glass beads on the sieve plate 513 from top to bottom, accelerating the falling speed of the glass beads, thereby accelerating the screening speed of the glass beads.

A number of screening holes are provided on the sieve plate 513. The inclined baffle is made of rubber material, which can buffer the falling glass beads and reduce the probability of the glass beads being damaged by collision. The glass beads fall onto the sieve plate 513 inside the screening spiral pipe 511, and the glass beads are screened. The vibration motor 505 drives the screening spiral pipe 511 to vibrate, accelerating the screening speed of the glass beads and reducing the probability of the glass beads getting stuck on the sieve plate 513. At the same time, the air inlet pipe 2 blows the glass beads on the sieve plate 513 from top to bottom, accelerating the falling speed of the glass beads, thereby accelerating the screening speed of the glass beads. The screened glass beads fall to the bottom of the screening spiral pipe 511, roll along the screening spiral pipe 511 to the inclined baffle, and the inclined baffle guides the glass beads into the interior of the discharge pipe 510, and the glass beads leave the screening spiral pipe 511 through the discharge pipe 510.

[0075] Above the tank body 103, an inlet funnel 101 is provided. Above the inlet funnel 101, a fixing plate 102 is fixed. The end of the limiting rod 501 is fixed below the fixing plate 102. A plurality of discharge holes 104 are provided on the side surface of the tank body 103.

[0076] It should be noted that the glass beads to be screened are conveyed above the inlet funnel 101. The inlet funnel 101 can guide the glass beads so that the glass beads all fall above the sieve plate 513.

[0077] A communication port 516 is provided on the discharge pipe 510, and a plurality of mutually staggered guide plates 517 are provided inside the discharge pipe 510.

[0078] It should be noted that a plurality of guide plates 517 are all made of rubber material. The plurality of mutually staggered guide plates 517 can slow down the falling glass beads, avoid the too fast falling speed of the glass beads, and avoid the damage probability caused by the collision of the falling glass beads.

[0079] The discharging mechanism 3 includes a conveyor belt 302. The conveyor belt 302 is located inside the discharge hole 104, and 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 blanking mechanism 6. The conveyor belt 302 intermittently conveys a plurality of packaging bottles 301 directly below the blanking mechanism 6. When the packaging bottles 301 are loaded with a fixed amount of glass beads, the packaging bottles 301 are conveyed out of the inside of the tank body 103.

[0081] The blanking mechanism 6 includes a collecting box 601. The collecting box 601 is fixed on the inner wall of the tank body 103. Below the collecting box 601, a cylinder 603 is fixed. Inside the cylinder 603, an auger 604 is rotatably arranged. Above the collecting box 601, a conveying motor 602 is fixed. The output shaft of the conveying motor 602 is connected to the auger 604 through a coupling. A blanking port 605 is provided below the cylinder 603.

[0082] It should be noted that the bottom of the collecting box 601 is inclined, and a rubber buffer layer is laid on the bottom of the collecting box 601, which can buffer the falling glass beads and reduce the probability of damage caused by the collision of the glass beads. The glass beads fall into the inside of the collecting box 601 from the discharge pipe 510. The collecting box 601 guides the glass beads into the inside of the cylinder 603. The conveying motor 602 drives the auger 604 to rotate through the output shaft. The auger 604 quantitatively conveys the glass beads and discharges the glass beads from the blanking port 605. By controlling the rotation speed of the auger 604, the number of conveyed glass beads is controlled to achieve quantitative conveying.

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

[0084] It should be noted that the backing plate 512 can buffer the glass beads falling after screening, reduce the probability of collision damage when the glass beads fall, and at the same time, reduce the speed of the glass beads during screening.

[0085] An isolation spiral plate 515 is fixed inside the screening spiral pipe 511. The isolation spiral plate 515 and the sieve plate 513 divide the inside of the screening spiral pipe 511 into an air inlet chamber, a screening chamber, and a blanking chamber. A number of air guiding inclined grooves 509 are formed on the isolation spiral plate 515, and the air inlet pipe 2 is communicated with the air inlet chamber;

[0086] It should be noted that the air inlet pipe 2 blows air into the inside of the air inlet chamber. When the air fills the inside of the air inlet chamber, the air is blown from a number of air guiding inclined grooves 509 onto the glass beads on the sieve 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, the glass beads fall into the inside of the blanking chamber. 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] A number of air guiding plates 514 are fixed below the sieve plate 513, and the air inlet pipe 2 is communicated with the air inlet chamber;

[0088] It should be noted that after the glass beads are screened, the glass beads fall into the inside of the blanking chamber. A number of air guiding plates 514 guide the screened glass beads, making the glass beads fall obliquely, increasing the initial speed when the glass beads fall. At the same time, a number of air guiding plates 514 can also re-guide the air only, continuously blowing the inside of the blanking chamber, thereby continuously accelerating the moving speed of the glass beads on the backing plate 512, so as to make full use of the air and accelerate the screening speed.
