AI Technical Summary
In the existing technology, the glass bead spreading speed is uncontrollable, resulting in uneven spreading of glass beads, which affects the retroreflection coefficient of the marking. In addition, the glass beads enter the molten marking at the same time, which affects the quality of the marking.
A follow-up glass bead spreading device for traffic markings was designed, including a mounting plate, a glass bead hopper, an elastic scraper, front and rear micro-groove rubber synchronous belt assemblies, and follow-up wheels. The rubber synchronous belt assembly is driven to rotate through a transmission structure to achieve uniform spreading of glass beads and control the time of spreading into the molten markings.
This method achieves compatibility between the glass bead spreading speed and the marking equipment, avoiding overspreading and missed spreading, improving the retroreflection coefficient and pass rate of the markings, and saving material consumption.

Abstract
Claims
1. A follow-up traffic marking glass bead spreader characterized by: The device includes a mounting plate, a glass bead hopper, an elastic scraper, a front microgrooved rubber synchronous belt assembly, a rear microgrooved rubber synchronous belt assembly, and follower wheels. The mounting plate is vertically arranged. A glass bead hopper is mounted on the outer side of the mounting plate via a fixing rod. At the bottom of the glass bead hopper, a front microgrooved rubber synchronous belt assembly and a rear microgrooved rubber synchronous belt assembly are arranged at intervals. The front and rear microgrooved rubber synchronous belt assemblies are mounted on the mounting plate. The front end of the front microgrooved rubber synchronous belt assembly forms a front discharge port, and the front end of the rear microgrooved rubber synchronous belt assembly forms a rear discharge port. A hopper discharge port is provided on the glass bead hopper at a position corresponding to the front and rear discharge ports. An elastic scraper is installed at each hopper discharge port, contacting the upper surface of the front and rear microgrooved rubber synchronous belt assemblies. A follower wheel is mounted on the bottom of the rear discharge port via a bracket. The follower wheel drives the front and rear microgrooved rubber synchronous belt assemblies to rotate through a transmission structure.
2. A follow-up traffic marking glass bead spreading device according to claim 1, characterized in that: Both the front and rear microgroove rubber synchronous belt assemblies include rollers, belts, shafts, and bearings. The rollers are arranged opposite each other, with belts wound around them. A shaft is coaxially mounted on each roller, extending from one end of the inner side of the roller and rotatably mounted on the bearing. The bearing is fixedly mounted on the mounting plate.
3. A follow-up traffic marking glass bead spreading device according to claim 2, characterized in that: The belt has a structure with evenly spaced microgrooves on its end face.
4. The follow-up traffic marking glass bead spreading device according to claim 1, characterized in that: The glass bead hopper includes a head body with openings at the top and bottom. An opening is provided at the front end of the hopper body, and a groove with an opening at the bottom is provided in the middle of the hopper body. The top wall and front wall of the groove are provided with wall plates, and the rear wall of the groove is open. These two openings form a material outlet.
5. The follow-up traffic marking glass bead spreading device according to claim 1, characterized in that: The transmission structure includes a vertical transmission chain, a horizontal transmission chain, a driving gear, a first driven gear, and a second driven gear. A follower wheel is mounted on the inner middle position of the front microgroove rubber synchronous belt assembly and the rear microgroove rubber synchronous belt assembly via a bracket. A driving gear that rotates synchronously with the follower wheel is mounted on the axle of the follower wheel. A first driven gear is mounted on one inner end of each of the two central rotating shafts, and a second driven gear is mounted on one outer end of each rotating shaft. A vertical transmission chain is meshed and wound around the driving gear and the two first driven gears above it. A horizontal transmission chain is meshed and wound between the two second driven gears on the front microgroove rubber synchronous belt assembly and the rear microgroove rubber synchronous belt assembly.
