Description

Technical Field

[0001] The utility model relates to the technical field of hot melt adhesives, in particular to a quantitative filler for hot melt adhesive processing. Background Art

[0002] Hot melt adhesive is a plastic adhesive that is solid at room temperature and can quickly bond when heated and melted. Hot melt adhesive is usually in granular form after production and then needs to be bottled and stored.

[0003] The traditional filling method is for the staff to pour the hot melt adhesive granules into the filling machine, then align the bottle mouth of the packaging bottle with the discharge port of the filling machine, and then start the filling machine to pour the hot melt adhesive granules into the packaging bottle. When the packaging bottle is almost full, close the discharge port of the filling machine and remove the packaging bottle.

[0004] However, with this manual filling method, it is difficult for workers to confirm the amount of hot melt adhesive filled by simply looking at it and feeling it, resulting in a large weight deviation in the amount of hot melt adhesive in the bottle. Utility Model Content

[0020] In order to better understand the above technical solution, the above technical solution will be described in detail below with reference to the accompanying drawings and specific implementation methods.

[0021] The present application discloses a quantitative filler for hot melt adhesive processing, referring to Figure 1 、 Figure 2 and Figure 3 , comprising a mounting base 1 and a feeding tank 2, the mounting base 1 being bolted to a mounting frame 11, and the feeding tank 2 being bolted to the mounting frame 11. A feeding port is provided on the top of the feeding tank 2, and a sealing cover 23 is installed at the feeding port. A discharge pipe 21 is welded to the bottom of the feeding tank 2, and a valve 22 is installed on the discharge pipe 21. A turntable 12 is rotatably provided on the mounting base 1 below the feeding tank 2, and a plurality of weighing pans 3 for weighing the weight of the packaging bottles 10 are provided on the turntable 12 at intervals along its circumference. The packaging bottles 10 on the weighing pans 3 are transported in sequence to the position directly below the discharge pipe 21 as the turntable 12 rotates, and a driving member for driving the turntable 12 to rotate is installed on the mounting base 1.

[0022] Specifically, the weighing pan 3 includes a mounting plate 31 and a weighing sensor 32. The mounting plate 31 is connected to the turntable 12 via the weighing sensor 32. The weighing sensor 32 is operatively connected to a display 33, which is mounted on the mounting base 1. The display 33 can display the weight of each packaged bottle 10 in real time.

[0023] In one embodiment of the present application, after a worker places multiple bottles 10 one by one on corresponding mounting plates 31, the driver can drive the turntable 12 to rotate so that the bottles 10 can be rotated sequentially to the discharge end of the discharge tube 21. When the bottles 10 rotate to the discharge end of the discharge tube 21, the driver stops working, and the worker can manually open the valve 22 and observe the weight of the bottle 10 in the filling state on the display 33. When the weight of the bottle 10 reaches the factory weight requirement, the worker immediately closes the valve 22. The driver then drives the turntable 12 to rotate to fill the next bottle 10. Compared to traditional filling methods, the quantitative filler of the present application can detect the weight of the bottle 10 in real time to quantitatively control the amount of hot melt adhesive, which has the effect of reducing the filling deviation of the hot melt adhesive.

[0024] In another embodiment of the present application, valve 22 is an electric valve, which is operatively connected to a controller, and the controller is operatively connected to a weighing sensor 32. The controller can be a computer control system and assembled in conjunction with a display 33. When the packaging bottle 10 rotates to the discharge end of the discharge pipe 21, the drive stops working, and the staff can control the valve 22 through the controller to open the discharge pipe 21 to pour the hot melt adhesive granules into the packaging bottle 10. When the corresponding weighing sensor 32 detects that the weight of the packaging bottle 10 reaches a preset value, the controller automatically controls the valve 22 to close the discharge pipe 21. The preset value is the factory weight value and can be set in the controller through programming. By electrically controlling the valve 22 to close the discharge pipe 21, the filling deviation of the hot melt adhesive can be further reduced.

[0025] Furthermore, a limiting assembly 5 for limiting the horizontal movement of the packaging bottle 10 is mounted on the mounting plate 31. The limiting assembly 5 includes a mounting barrel 51 and a plurality of limiting bolts 52. The mounting barrel 51 is coaxially bolted to the mounting plate 31, and the plurality of limiting bolts 52 are threadedly connected to the side wall of the mounting barrel 51 along the radial direction of the mounting barrel 51.

[0026] In the embodiment of the present application, after the packaging bottle 10 is placed in the installation cylinder 51, multiple limit bolts 52 are rotated one by one to make them contact the outer wall of the packaging bottle 10. This can prevent the hot melt adhesive particles from hitting the inner wall of the packaging bottle 10 during the filling process and causing the packaging bottle 10 to shift, thereby improving the filling stability.

[0027] Furthermore, a flexible block 6 is sleeved on the end of the limiting bolt 52 located in the installation tube 51 , and the flexible block 6 abuts against the outer wall of the packaging bottle 10 .

[0028] In this embodiment, the flexible block 6 is made of rubber. After placing the bottle 10 in the mounting barrel 51, the operator can rotate the multiple retaining bolts 52 to force the flexible block 6 into contact with the outer wall of the bottle 10, further securing the bottle 10. Because the flexible block 6 has a certain degree of elasticity, when subsequently replacing the bottle 10, the operator simply inserts the bottle 10 into the mounting barrel 51 and engages the multiple flexible blocks 6.

[0029] Furthermore, a guide head 7 for inserting into the packaging bottle 10 is vertically slidably connected to the discharge port of the discharge pipe 21. A through hole communicating with the discharge pipe 21 is vertically penetrated through the guide head 7, and the outer wall of the guide head 7 is set to a conical surface.

[0030] When the bottle 10 rotates to the discharge end of the discharge tube 21, the sidewall of the bottle's mouth slides against the conical surface, driving the guide head 7 upward. The guide head then moves downward and engages the bottle's mouth. When the bottle 10 is filled, the driver rotates the turntable 12, causing the sidewall of the bottle's mouth to slide against the conical surface again, driving the guide head 7 upward, allowing the bottle 10 to be transported away from the discharge end of the discharge tube 21. This prevents hot melt adhesive particles from spilling out of the bottle 10.

[0031] In order to facilitate the staff to take and place the packaging bottle 10, the surface of the flexible block 6 that is in contact with the packaging bottle 10 is set to be a hemispherical surface.

[0032] Specifically, the driving component includes a first driving motor 4 . The first driving motor 4 is mounted on the mounting base 1 , and an output shaft of the first driving motor 4 is drivingly connected to the turntable 12 .

[0033] Furthermore, a stirring bracket 8 is rotatably mounted within the feeding tank 2 at the discharge pipe 21. A rotating shaft is vertically welded to the stirring bracket 8. One end of the rotating shaft extends through the top of the feeding tank 2 and is connected to a second drive motor 9. Activating the second drive motor 9 rotates the stirring bracket 8 and stirs the hot melt adhesive pellets in the feeding tank 2 at the discharge pipe 21 to prevent the pellets from clogging the discharge pipe 21.

[0034] The working principle of a quantitative filler for hot melt adhesive processing in an embodiment of the present application is as follows: a worker places multiple bottles 10 one by one on corresponding mounting plates 31. The driver can then drive the turntable 12 to rotate so that the bottles 10 can rotate sequentially to the discharge end of the discharge tube 21. When the bottles 10 rotate to the discharge end of the discharge tube 21, the driver stops working, and the worker can open the valve 22 to pour the hot melt adhesive granules into the bottles 10 and observe the weight of the filled bottles 10 on the display 33. Once the weight of the bottles 10 reaches the factory weight requirement, the worker immediately closes the valve 22. The driver then drives the turntable 12 to rotate to fill the next bottle 10. Compared to traditional filling methods, the quantitative filler of the present application can detect the weight of the bottles 10 in real time to quantitatively control the amount of hot melt adhesive, which has the effect of reducing the filling deviation of the hot melt adhesive.
