Description

Technical Field

[0001] The utility model relates to the technical field of road marking equipment, in particular to a glass bead feeding device. Background Art

[0002] Reflective glass beads possess excellent reflective and refractive properties, effectively reflecting light back in the direction of the light source, creating a strong reflective effect. This characteristic makes them highly visible at night or in low-light conditions, thereby improving road visibility. With the growing market demand for road marking equipment, the proper amount of glass beads must be dispensed during the coating process to ensure nighttime legibility. As an essential component of road marking equipment, glass bead boxes are becoming increasingly important. However, existing glass bead boxes for small road marking equipment suffer from issues such as poor material discharge and severe material accumulation. Patent document CN215561806U discloses a glass bead box for road marking equipment. The lower half of the glass bead box forms a funnel-shaped discharge channel. The short side of the lower curved plate is provided with a discharge port, and an elbow is welded below the discharge port. The glass beads are poured into the box and filtered by a filtering device. They automatically slide into the discharge port under their own gravity and then flow out through the elbow. The glass beads are spread after being filtered, which greatly improves the smoothness of the glass bead discharge. At the same time, due to the unique structure of the glass bead box, the problem of excessive accumulation of glass beads in the box is also avoided.

[0003] The above-mentioned device still has some shortcomings in practical application. Although it can prevent excessive accumulation of glass beads in the box and improve the smoothness of glass bead discharge, it is prone to material accumulation at the elbow when the device stops feeding and then discharges again, leading to accumulation and blockage. This is because the inner diameter of the elbow is small, and the material that is screened by the filter screen in the box during the interruption process will be concentrated and blocked in the inner area of ​​the lower bend plate and the inner side of the elbow due to the impact. In other words, the device can only be used for one-time feeding and has certain limitations. Therefore, it is necessary to provide a glass bead feeding device to solve the above-mentioned problems.

DETAILED DESCRIPTION

[0017] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific embodiments of the present invention are described in detail below with reference to the accompanying drawings.

[0018] Next, the present invention is described in detail with reference to schematic diagrams. For ease of illustration, cross-sectional views of device structures may be partially enlarged and not to scale when describing the embodiments of the present invention. Furthermore, the schematic diagrams are merely illustrative and should not limit the scope of protection of the present invention. Furthermore, in actual production, three-dimensional dimensions, including length, width, and depth, should be included.

[0019] In order to make the purpose, technical solutions and advantages of the present invention more clear, the embodiments of the present invention will be described in further detail below with reference to the accompanying drawings.

[0020] Figure 1-Figure 3 The diagram shows the entire structure of a glass bead feeding device of the present invention. Figure 1-Figure 3, a glass bead feeding device of the present embodiment includes a storage box 100, a corner of the inner bottom of the storage box 100 is provided with a discharge port 101, the edge of the discharge port 101 is provided with a material guide slope 102 extending to the inner wall of the storage box 100, and an electromagnetic ball valve 200 is provided on one side of the bottom of the storage box 100, the input end of which corresponds to the discharge port 101, and a feeding cylinder 300 is horizontally arranged at the bottom of the electromagnetic ball valve 200, and the input end of the feeding cylinder 300 is connected to the output end of the electromagnetic ball valve 200, and a spiral push rod 310 driven by a driving device to rotate is provided on the inside of the feeding cylinder 300 along its length direction, and the bottom of the output end of the feeding cylinder 300 is connected to a distribution plate 400 with a hollow interior.

[0021] The top opening of the storage box 100 is also equipped with a cover plate 110, and a handle 111 is also provided on one side of the top of the cover plate 110. It can be understood that by opening the cover plate 110, glass beads can be easily added to the storage box 100. The cover plate 110 and the storage box 100 can be hinged, slidably, or vertically interlocked, etc., without limitation. A servo motor 320 is provided at one end of the outer side of the feed barrel 300, and the output shaft of the servo motor 320 is connected to one end of the screw push rod 310. The bottom of the output end of the feed barrel 300 also has a discharge nozzle 330 connected to the cloth plate 400. It should be noted that the inner diameter of the discharge nozzle 330 is large enough to at least be saturated to cope with the high-speed output and feeding of the screw push rod 310. The cloth plate 400 has a straight transition structure that is narrow at the top and wide at the bottom, and the outlet at the bottom of the cloth plate 400 is a wide and flat structure. In this embodiment, to ensure a more uniform distribution of glass beads, a uniquely designed distribution plate 400 is used. This allows the beads entering from above to be evenly dispersed through spatial constraints, preventing accumulation at the end of the feed, resulting in a better distribution effect. Specifically, when the material is stopped midway and re-fed, the funnel-shaped storage box 100 is used to allow the material to slide freely into the discharge port 101. The electromagnetic ball valve 200 then opens, allowing the material to enter the feed cylinder 300. The uniformly rotating screw push rod 310 evenly and quantitatively conveys the incoming material to the discharge nozzle 330, where it is further distributed through the distribution plate 400. This significantly improves the smoothness of glass bead discharging and avoids accumulation during the feeding process. The machine can be stopped mid-flight according to construction needs without affecting the next feeding, further enhancing its practicality.

[0022] Furthermore, a laser rangefinder 500 is provided on the top of the inner side of the storage box 100 and mounted on the bottom of the cover plate 110. It is understood that the glass beads in the storage box 100 are continuously consumed during use. Therefore, the laser rangefinder 500 can measure the distance between the top of the material and the cover plate 110 in real time as the material sinks. When the distance reaches a set value, it means that the material is about to be consumed. At this time, the control unit will promptly remind the staff to add or refill the material after receiving feedback.

[0023] Further, a visual window 120 is also provided on one side of the storage box. In actual application, the staff can also check the consumption of the material inside the box through the visual window 120, and the practicality is further improved.

[0024] In summary, a glass bead feeding device according to the present embodiment, when in use, when the material stops halfway and is fed again, the storage box 100 with a funnel-shaped inner cavity is adopted to allow the material to slide freely into the discharge port 101, and then the electromagnetic ball valve 200 is opened to allow the material to enter the feeding barrel 300, and the spiral push rod 310 rotating at a uniform speed can evenly and quantitatively transport the incoming material to the discharge nozzle 330, and then the material is further spread through the distribution plate 400, which greatly improves the smoothness of glass bead discharge and avoids the accumulation of glass beads during feeding. The machine can be stopped according to construction needs during use without affecting the next feeding.

[0025] While the present invention has been described above with reference to specific embodiments, various modifications may be made and equivalent components may be substituted without departing from the scope of the present invention. In particular, as long as no structural conflicts exist, the various features of the embodiments disclosed herein may be combined with one another in any manner, and the omission of an exhaustive description of these combinations in this specification is solely for the sake of space and resource conservation. Therefore, the present invention is not limited to the specific embodiments disclosed herein, but encompasses all technical solutions within the scope of the claims.
