[0027] See also Figure 1-6 The utility model provides a technical solution: a filling device for the production of hot melt adhesive for headlights, comprising a workbench 1, a cylinder 11 is fixedly connected to the inner top of the workbench 1, a vertical plate 12 is fixedly connected to the top of the cylinder 11, a reciprocating mechanism is connected to one side of the vertical plate 12, a rotating mechanism is connected to the top of the cylinder 11, a round block 37 is connected to the bottom of the rotating mechanism, the reciprocating mechanism and the round block 37 are connected, a stirring blade 38 is fixedly connected to the outer side of the round block 37, an outlet is opened at the bottom of the cylinder 11, two opening and closing doors 14 are slidably connected to the bottom of the cylinder 11, and an opening and closing mechanism is connected to the inside of the opening and closing door 14; when the staff is ready to start the filling work, first fill the inside of the cylinder 11 with hot melt adhesive, and heat the inside of the cylinder 11 at the same time, at this time the staff turns on the rotating mechanism and the reciprocating mechanism, the internal round block 37 and the stirring blade 38 can reciprocate up and down, so that the internal hot melt adhesive is evenly distributed and evenly heated, and when filling, the staff controls the opening and closing mechanism to open, and the internal hot melt adhesive can flow out for filling. By providing a reciprocating mechanism and a rotating mechanism, the internal hot melt adhesive can be stirred by rotating up and down. The stirring area is increased, and the hot melt adhesive is evenly distributed and heated in the cylinder 11, thereby improving the filling quality. By providing an opening and closing mechanism, the filling process can be automatically controlled. The opening and closing mechanism can be opened automatically, thereby realizing the start and end of filling. This not only saves manpower, but also improves work efficiency.

[0028] The reciprocating mechanism includes a first motor 2, the first motor 2 and the vertical plate 12 are fixedly connected, and the output end of the first motor 2 is provided with a first rotating shaft 21, a rotating block 22 is fixedly connected to one side of the first rotating shaft 21, a convex block 23 is fixedly connected to one side of the rotating block 22, an O-shaped block 24 is slidably connected to the outer side of the convex block 23, and a round rod 25 is fixedly connected to one side of the O-shaped block 24, and the round rod 25 is connected to the round block 37; when the staff turns on the first motor 2, the first rotating shaft 21 at the output end rotates, the rotating block 22 will rotate, and the convex block 23 is fixedly connected to the side end of the rotating block 22, so that the convex block 23 will also rotate accordingly, and slide inside the O-shaped block 24 while rotating, and when it slides to the end of the O-shaped block 24, it can no longer slide, but the convex block 23 still needs to continue to rotate, so that the convex block 23 can lead the O-shaped block 24 downward or upward, so that the round rod 25 will move up and down, and lead the round block 37 to move up and down, that is, move up and down to stir. By providing a reciprocating mechanism, the device can stir up and down reciprocatingly, thereby increasing the stirring area and making the internal stirring more uniform.

[0029] A circular ring 26 is fixedly connected to the bottom of the round rod 25, and a circular groove is opened inside the top of the round block 37, and the circular ring 26 corresponds to the circular groove; the circular ring 26 is in the circular groove inside the round block 37, and when the round block 37 rotates driven by the rotating mechanism, it has no effect on the circular ring 26, that is, the rotation and reciprocating lifting will not conflict, and when the round rod 25 descends, the circular ring 26 descends, and the circular ring 26 presses the circular groove to drive the round block 37 to descend, and the same principle applies to the ascent.

[0030] A positioning block 13 is fixedly connected to one side of the vertical plate 12, and the round rod 25 and the positioning block 13 are slidably connected; the positioning block 13 mainly restricts the round rod 25 to move only in the direction inside the positioning block 13.

[0031] The rotating mechanism includes a second motor 3, which is fixedly connected to the top of the cylinder 11. A second rotating shaft 31 is provided at the output end of the second motor 3. A first gear 32 is fixedly connected to one side of the second rotating shaft 31. A second gear 33 is meshedly connected to one side of the first gear 32. The middle of the second gear 33 is hollow. The round rod 25 passes through the middle of the second gear 33. A moving rod 34 is fixedly connected to the bottom of the second gear 33. A hollow rod 35 is slidably connected to the outer side of the moving rod 34. The hollow rod 35 and the round block 37 are fixedly connected. When the staff turns on the second motor 3, the second rotating shaft 31 at the output end rotates, the first gear 32 rotates, and the second gear 33 rotates, so that the bottom moving rod 34 will rotate, but it is connected to the hollow rod 35 by sliding, and theoretically cannot rotate together, but the long strip 36 outside the moving rod 34 can rotate with the long groove, so the hollow rod 35 rotates, and then the round block 37 at the bottom rotates. The sliding connection between the hollow rod 35 and the moving rod 34 is mainly to cooperate with the lifting and lowering of the reciprocating mechanism, so that there is no conflict between lifting and rotating. By providing a rotating mechanism, the internal rotating stirring can make the hot melt adhesive evenly distributed to prevent uneven concentration after filling.

[0032] The positioning block 13 and the second gear 33 are rotationally connected; the positioning block 13 mainly provides a certain support for the second gear 33, and the rotational connection ensures that the second gear 33 can rotate.

[0033] A long strip 36 is fixedly connected to the outer side of the moving rod 34, and a long groove is opened on the inner side of the hollow rod 35, and the long strip 36 corresponds to the long groove; the long strip 36 is inside the long groove, and when the moving rod 34 rotates, the long strip 36 rotates, and the long strip 36 presses the inner side of the long groove, so that the hollow rod 35 can be rotated, and the reciprocating mechanism ensures that it will not fall in the up and down directions. The ring 26 of the reciprocating mechanism pulls the round block 37, and the device as a whole is stable.

[0034] The opening and closing mechanism includes a third motor 4, which is fixedly connected to the bottom of the cylinder 11. A third rotating shaft 41 is provided at the output end of the third motor 4, and the third rotating shaft 41 is connected to the two opening and closing doors 14. When the staff turns on the third motor 4, the third rotating shaft 41 rotates, and the two opening and closing doors 14 open. By controlling the rotation direction of the third motor 4, the opening and closing doors 14 can be closed or opened, thereby realizing the start and end of filling. Only the motor needs to be controlled, which saves manpower.

[0035] Two threads are provided on the outer side of the third rotating shaft 41, and the threads are in opposite directions. The third rotating shaft 41 and the opening and closing door 14 are threadedly connected; the third rotating shaft 41 has two threads on the outer side, one thread corresponds to one opening and closing door 14, and the two threads are in opposite directions. In this way, when the third rotating shaft 41 rotates, the two threads can open the opening and closing door 14, and the opening and closing door 14 can be closed by controlling the rotation direction of the third rotating shaft 41.
