Description

Technical Field

[0001] The utility model relates to the field of plastic barrel production, and more particularly to a barrel cover marking mechanism. Background Art

[0002] The blending oil barrels commonly found on the market mostly adopt the injection molding process. After production, a barrel mouth will be left on the top for the convenience of filling and use. Therefore, after filling, the barrel mouth needs to be sealed with a barrel cover. The barrel cover and the barrel body are connected by threads. In order to facilitate the production and sales of subsequent products, the surface of the barrel cover will be marked, so a corresponding marking machine will be used. Existing marking machines mostly use lasers to mark the surface of the product. In order to improve production efficiency, existing marking machines will connect and transport the products through conveyor belts. However, due to the light texture of the barrel cover, inaccurate positioning is often caused by mutual squeezing of the barrel covers or conveying inertia during transportation, which in turn causes deviation in the marking position and affects the marking effect.

[0020] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention; it is obvious that the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0021] Example:

[0022] See also Figure 1 and Figure 2 As shown, a barrel cover marking mechanism includes a workbench 1 and a storage barrel 19. A guide plate 2 is provided at the discharge end of the workbench 1. The guide plate 2 is tilted downward to guide the barrel cover after marking. Support plates 3 are symmetrically provided on both sides of the top of the workbench 1. A control motor 4 is provided on the outside of one of the support plates 3. A conveyor belt 5 is installed inside the support plate 3. The control motor 4 controls the conveyor belt 5. The control motor 4 is a servo motor that can accurately control the movement of the conveyor belt 5. The movement of the conveyor belt 5 drives multiple barrel covers to be transported. The outer surface of the conveyor belt 5 is evenly provided with ridges 51. Adjacent ridges are evenly provided with ridges 51. The distance between the two ridges 51 is equal to the diameter of the barrel cover, so that the barrel cover is placed exactly between the two ridges 51 during unloading to prevent relative sliding between the barrel cover and the conveyor belt 5. A column 6 is vertically arranged on the rear side of the upper surface of the workbench 1, and a slide groove 7 is provided on the surface of the column 6. A threaded rod 10 is vertically and rotatably installed inside the slide groove 7. A lifting rod 8 is slidably installed on the front side of the slide groove 7. The threaded rod 10 is screwed through the lifting rod 8. A marking body 9 is arranged at the front end of the lifting rod 8. The marking body 9 is placed directly above the conveyor belt 5 to improve the flexibility of the marking body 9. The marking body 9 is a laser emitter.

[0023] Please refer to Figure 2 and Figure 3As shown, the upper surface of the workbench 1 is provided with a track groove 12, and the track groove 12 is symmetrically slidably installed with a moving block 15. A connecting rod 16 is vertically provided on the top of the moving block 15. The connecting rod 16 is L-shaped, and a limiting cross bar 17 is provided at one end of the connecting rod 16 away from the moving block 15. The two limiting cross bars 17 are respectively placed on both sides above the conveyor belt 5, and the two limiting cross bars 17 are respectively placed on both sides of the barrel cover. When in use, the two limiting cross bars 17 are adjusted to be placed on both sides of the barrel cover to limit the barrel cover. At this time, the barrel cover is affected by the two adjacent convex strips 5 1, and the two limiting cross bars 17 are used to ensure the stability of the barrel cover. A double screw 13 is rotatably installed inside the track groove 12. The double screw 13 passes through the front end surface of the workbench 1. A knob 14 is provided at the front end of the double screw 13. Two moving blocks 15 are respectively screwed on different thread surfaces of the double screw 13. When replacing a different barrel cover, the double screw 13 can be driven to rotate by rotating the knob 14 externally, thereby driving the two limiting cross bars 17 to move closer to or away from each other to adapt to the marking work of barrel covers of different sizes.

[0024] Please refer to Figure 1 and Figure 2 As shown, the storage barrel 19 is suspended at the feeding end of the conveyor belt 5, and support rods 20 are symmetrically arranged on the bottom of both sides of the storage barrel 19. The bottom of the support rod 20 is fixed to the upper surface of the workbench 1, and the two support rods 20 span the two sides of the conveyor belt 5. The distance between the lower end surface of the storage barrel 19 and the conveyor belt 5 is greater than the thickness of a single barrel cover, but less than twice the thickness of the barrel cover, so that only one barrel cover can pass through the gap between the two. The barrel covers inside the storage barrel 19 are stacked and will fall to the surface of the conveyor belt 5 due to their own weight, and the bottom barrel cover is in contact with the surface of the conveyor belt 5. When the conveyor belt 5 moves during operation, the barrel cover can be pushed by the ridge 51 so that the barrel cover moves with the conveyor belt 5.

[0025] Among them, a cone 21 is provided on the top of the storage barrel 19 to facilitate adding a barrel cover to the inside of the storage barrel 19, and an observation window 22 is opened on the surface of the storage barrel 19 to facilitate observing the barrel cover inside the storage barrel 19.

[0026] Please refer to Figure 1-Figure 3 As shown, the two limiting cross bars 17 are each provided with a guiding oblique rod 171 at one end close to the storage barrel 19 , and the guiding oblique rod 171 is opened outward at one end away from the limiting cross bar 17 to move the barrel cover so that the barrel cover is placed at the center position of the conveyor belt 5 .

[0027] Please refer to Figure 1 and Figure 2 As shown, an air suction cylinder 18 is fixed on the top of the limiting cross bar 17 close to the side of the column 6, and a dust suction pump 11 is fixed on one side of the column 6. The rear end of the air suction cylinder 18 is connected to the inlet and outlet of the dust suction pump 11 through a hose to absorb the exhaust gas during marking, and can be applied to different barrel cover marking tasks.

[0028] Working principle: First, adjust the distance between the two limiting cross bars 17 according to the diameter of the barrel cover. During adjustment, control the double screw 13 to rotate through the knob 14, and then control the two moving blocks 15 to approach or move away from each other through different threaded surfaces, and then control the distance between the two limiting cross bars 17 to limit the barrel cover transported on the surface of the conveyor belt 5, and control the height of the lifting rod 8 by rotating the threaded rod 10, and then control the height of the marking body 9 to mark the barrel cover passing below. When in use, multiple barrel covers are stacked inside the storage barrel 19, and the conveyor belt 5 is driven to move by controlling the motor 4. The barrel covers inside the storage barrel 19 will fall one by one on the upper surface of the conveyor belt 5. Since the gap between the storage barrel 19 and the conveyor belt 5 can only pass one barrel cover, the barrel cover can be evenly placed between the two ridges 51, and then the barrel cover is placed in the center position of the conveyor belt 5 through the guidance of the guide diagonal rod 171 during the movement, so as to facilitate marking of multiple passes.

[0029] The above description is merely a preferred embodiment of the present invention; however, the scope of protection of the present invention is not limited thereto. Any person skilled in the art who, within the technical scope disclosed in the present invention, makes equivalent substitutions or modifications based on the technical solutions and improved concepts of the present invention shall be covered by the scope of protection of the present invention.
