Description

Technical Field

[0001] This invention relates to the field of asphalt packaging technology, specifically to an automatic packaging equipment for small packages of asphalt. Background Technology

[0002] Asphalt has the characteristics of good water resistance, strong resistance to deformation, strong resistance to aging, and high flash point, so it is often used for road surface paving. After production, asphalt needs to be packaged, that is, packaged into containers of the same size for storage or sale. The feeding height of existing packaging equipment cannot be adjusted. When the receiving bucket itself is small, the distance between the bucket opening and the discharge port is too far, which can easily cause the product to splash out.

[0003] Chinese patent discloses an asphalt filling machine with lifting function (authorization announcement number CN217535450U). This patented technology involves placing a receiving bucket on a conveying device, moving it to the exact position below the discharge pipe, and controlling the extension and retraction of a telescopic cylinder to rotate a movable arm. The bottom end of the movable arm moves along a chute via a movable seat, thereby allowing the top end to move a sliding component up and down along a support rod. The support rod, through a connecting rod, drives the discharge pipe to extend and retract up and down, adjusting the height of the discharge port to further improve the filling effect. The structure is simple and easy to use, and the height of the discharge port can be adjusted according to different bucket sizes to ensure filling stability and effect. However, it has certain drawbacks: during the process of filling the receiving bucket and replacing it with another receiving bucket, asphalt drips onto the conveying device, easily causing waste and pollution, a problem that cannot be avoided. Therefore, those skilled in the art have provided an automatic small-package asphalt dispensing device to solve the problems mentioned in the background art. Summary of the Invention

A lifting mechanism adjusts the height of the asphalt tank, thereby regulating the distance between the electric valve and the packaging drums to prevent splashing or tipping of the drums during discharge. A stirring mechanism agitates the asphalt to prevent sedimentation. Attached Figure Description

[0025] Please see Figure 1 and Figure 2 In this embodiment of the invention, the automatic packaging equipment for small packages of asphalt includes a base plate 1. A rotary weighing mechanism 2 is installed on the upper surface of the base plate 1. Multiple packaging barrels 3 are evenly placed on the upper surface of the rotary weighing mechanism 2. A support rod 4 is installed on the upper surface of the base plate 1 behind the rotary weighing mechanism 2. A lifting rod 5 is slidably connected inside the support rod 4. An asphalt tank 7 is installed at the upper end of the lifting rod 5. An electric valve 8 is installed at the lower end of the asphalt tank 7. The electric valve 8 is directly opposite a packaging barrel 3. The rotary weighing mechanism 2 includes a support base 9, which is installed on the upper surface of the base plate 1. A weighing sensor 10 is installed at the center of the lower inner surface of the support base 9. Limit rods 11 are installed on both the front and rear sides of the weighing sensor 10 on the lower inner surface of the support base 9. A first limit rod 11 is slidably connected at the upper inner end of the support base 9. A support plate 12 is provided, with the upper end of the weighing sensor 10 attached to the lower surface of the first support plate 12. A limiting rod 11 movably passes through the first support plate 12. A support frame 13 is installed on the upper surface of the first support plate 12. A first motor 14 is installed on the right side surface of the support frame 13. A docking rod 15 is installed on the left end of the first motor 14. A first gear 16 is installed on the left end of the docking rod 15. A rotating rod 17 is rotatably connected through the upper surface of the support frame 13. A second gear 18 is installed at the lower end of the rotating rod 17. The first gear 16 is meshed with the second gear 18. A second support plate 19 is installed at the upper end of the rotating rod 17. Multiple limiting rings 20 are evenly installed on the outer edge of the upper surface of the second support plate 19. The number of packaging barrels 3 is equal to the number of limiting rings 20. The packaging barrels 3 are movably placed inside the limiting rings 20.

[0026] Asphalt tank 7 is filled with asphalt 41. Packaging drum 3 has a small capacity, approximately ten kilograms. Electric valve 8, weighing sensor 10, and first motor 14 are all electrically connected to an external control system, enabling automated operation. Opening electric valve 8 allows asphalt 41 to be discharged into packaging drum 3. The number of readings detected by weighing sensor 10 corresponds to the number of packaging drums. For example, when weighing sensor 10 detects a weight of eleven kilograms, it indicates that one packaging drum 3 is full. At this point, the first motor 14 rotates the second support plate 19 by a certain angle, positioning another packaging drum 3 below electric valve 8, thus opening electric valve 8. When the weighing sensor 10 detects a weight of 22 jin (approximately 11 kg), it indicates that the second packaging barrel 3 is full. At this time, the first motor 14 drives the second support plate 19 to rotate again by a certain angle, so that the other packaging barrel 3 is located below the electric valve 8. The electric valve 8 is opened. When the weighing sensor 10 detects a weight of 33 jin (approximately 11.5 kg), the first motor 14 drives the second support plate 19 to rotate again by a certain angle, so that the other packaging barrel 3 is located below the electric valve 8. This process is repeated. After several packaging barrels 3 are full, the electric valve 8 is closed, all packaging barrels 3 are removed, and new packaging barrels 3 are placed into all the limit rings 20.

[0027] exist Figure 1 and Figure 3 In the middle: The front surfaces of the support rod 4 and the lifting rod 5 are jointly provided with a lifting mechanism 6. The lifting mechanism 6 includes a fixed seat 21. The rear end of the fixed seat 21 is installed at the upper end of the front surface of the support rod 4. A second motor 22 is installed on the lower surface of the fixed seat 21. A threaded rod 23 is installed at the upper end of the second motor 22. A lifting block 24 is connected to the external thread of the threaded rod 23. The rear end of the lifting block 24 is installed on the front surface of the lifting rod 5.

[0028] The second motor 22 is electrically connected to the external control system and operates automatically under the control of the external control system. The second motor 22 drives the threaded rod 23 to rotate, which in turn drives the lifting rod 5 to rise and fall, thereby adjusting the height of the asphalt tank 7. It can also adjust the distance between the electric valve 8 and the packaging barrel 3 to prevent the asphalt 41 from splashing out or the barrel from tipping over when they are too far apart.

[0029] exist Figure 1 , Figure 4 and Figure 5In the middle: An external storage mechanism 25 is provided for the asphalt tank 7. The storage mechanism 25 includes a mounting sleeve 26, which is installed on the outside of the asphalt tank 7. Multiple mounting bolts 27 are threaded through and connected to both the front and rear surfaces of the mounting sleeve 26. One end of the mounting bolt 27 is attached to the asphalt tank 7, and mounting posts 28 are rotatably connected to both the left and right surfaces of the mounting sleeve 26. A first mounting rod 29 is installed on the outside of the mounting post 28, and a second mounting rod 30 is installed on one side of the front end of the first mounting rod 29. The two second mounting rods 30 are connected to each other. A connecting sleeve 31 is rotatably connected between the two parts. Multiple connecting rods 32 are evenly installed on the lower surface of the connecting sleeve 31, and a connecting plate 33 is installed below the connecting sleeve 31. The lower ends of the connecting rods 32 are installed on the upper surface of the connecting plate 33. A storage bucket 34 is movably placed inside the connecting sleeve 31 and is placed on the upper surface of the connecting plate 33. A mounting bracket 35 is installed on the left side surface of the mounting sleeve 26, and a third motor 36 is installed on the left side surface of the mounting bracket 35. The third motor 36 is connected to one end of the left mounting column 28.

[0030] When a packaging barrel 3 is full, the rotary weighing mechanism 2 will rotate once after a delay of several seconds. During this time, the third motor 36 drives the first mounting rod 29 to rotate downwards to a vertical position, so that the connecting sleeve 31 is located directly below the electric valve 8. In this way, the storage barrel 34 can catch the asphalt 41 dripping from the electric valve 8, avoiding waste and pollution caused by the dripping of asphalt 41. When a new packaging barrel 3 is located below the electric valve 8, the third motor 36 drives the first mounting rod 29 to rotate from a vertical position to a horizontal position.

[0031] exist Figure 1 and Figure 6 In the asphalt tank 7, an agitator 37 is installed at the upper part of the interior. The agitator 37 includes a top plate 38. Both ends of the front end of the top plate 38 are installed at the upper part of the interior surface of the asphalt tank 7. A fourth motor 39 is installed on the upper surface of the top plate 38. An agitator 40 is installed at the lower end of the fourth motor 39. The fourth motor 39 drives the agitator 40 to rotate and agitate the asphalt 41 to prevent the asphalt 41 from settling.

[0032] The working principle of this invention is as follows: In use, the electric valve 8 opens to discharge asphalt 41 into the packaging drum 3. Once the packaging drum 3 is full, the electric valve 8 closes, and the third motor 36 drives the first mounting rod 29 to rotate downwards to a vertical position, so that the connecting sleeve 31 is directly below the electric valve 8. In this way, the receiving drum 34 can catch the asphalt 41 dripping from the electric valve 8. When a new packaging drum 3 rotates to a position below the electric valve 8 under the drive of the rotating weighing mechanism 2, the third motor 36 drives the first mounting rod 29 to rotate from a vertical position to a horizontal position, and so on. When all the packaging drums 3 are full, the electric valve 8 closes, and the staff can remove all the packaging drums 3 and place the new packaging drums 3 into all the limiting rings 20. The staff can then turn on the second motor 22 to drive the threaded rod 23 to rotate, thereby driving the lifting rod 5 to lift and lower, which facilitates the adjustment of the height of the asphalt tank 7 and prevents the electric valve 8 from being too far away from the packaging drum 3, which could cause the asphalt 41 to splash out or the drum to tip over.

[0033] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the invention can be implemented in other specific forms without departing from its spirit or essential characteristics. Therefore, the embodiments should be considered in all respects as exemplary and non-limiting, and the scope of the invention is defined by the appended claims rather than the foregoing description. Thus, all variations falling within the meaning and scope of equivalents of the claims are intended to be included within the present invention.
