[0002] Ampoules are widely used as common pharmaceutical packaging containers.

[0004] However, manual ignition relies on manual operation, which is cumbersome and cannot achieve convenient and automatic ignition, resulting in low ignition efficiency. Therefore, an automatic ignition mechanism for the burner nozzle of an ampoule drawing and sealing machine is proposed. Utility Model Content

[0027] Reference Figure 1-5 As shown, this utility model provides a technical solution for an automatic ignition mechanism for the burner nozzle of an ampoule drawing and sealing machine:

[0028] An automatic ignition mechanism for the burner nozzle of an ampoule drawing and sealing machine includes a top plate 1. Several burner nozzles 2 are arranged at the front end of the bottom of the top plate 1. Side fixing plates 11 are provided on the left and right sides of the top plate 1. The side fixing plates 11 have fixing openings for fixing the mechanism at an appropriate position on the drawing and sealing machine. A rotating shaft 3 is rotatably connected to the side fixing plates 11 near the front end of the top plate 1. Both ends of the rotating shaft 3 are provided with end cavity blocks 31. The end cavity blocks 31 are connected to high-temperature resistant metal wires 33 through connectors 32. The two ends of the high-temperature resistant metal wires 33 are connected to wires 34. The ends of the two wires 34 are connected to plugs 35.

[0029] The formula that needs further explanation is that the burner 2 is existing technology and will not be elaborated on here.

[0030] The high-temperature resistant metal wire 33 can be placed at the front end of several burners 2 by rotating the shaft 3. It should be noted that the high-temperature resistant metal wire 33 can be made of platinum-rhodium alloy wire, tungsten wire, etc. It heats up after being energized, thereby igniting the gas sprayed from the burner 2.

[0031] Reference Figure 1 As shown, in an optional embodiment: the rotating shaft 3 is slidably connected to the short shaft 4, and both ends of the short shaft 4 are provided with limit blocks 41 to restrict the short shaft 4 from disengaging from the rotating shaft 3.

[0032] Reference Figure 2 As shown, in an optional embodiment: a limiting pad 42 is provided on the top surface of the top plate 1 at the front end of the short shaft 4. When the limiting end block 41 at the front end of the short shaft 4 abuts against the limiting pad 42, the high-temperature resistant metal wire 33 is placed at the front end of several burners 2.

[0033] Reference Figure 1 As shown, in an optional embodiment, a pull ring 43 is connected to the limiting end block 41 at the rear end of the short shaft 4, which is used to pull the short shaft 4 while controlling the rotation of the rotating shaft 3, thereby improving the user's operating efficiency.

[0034] Reference Figure 1 As shown, in an optional embodiment, the high-temperature resistant metal wire 33 is in a taut state. It should be noted that the high-temperature resistant metal wire 33 is in a taut state after being straightened to avoid bending and unnecessary increase in its length, which would lead to an unnecessary increase in the power consumption of the mechanism after it is energized.

[0035] Reference Figure 4 and Figure 5 As shown, in an optional embodiment: the end cavity block 31 is provided with an inner cavity, and the end of the connector 32 facing the end cavity block 31 is provided with an inner recess. (Refer to...) Figure 5 As shown, in an optional embodiment: the end cavity block 31 has a threaded interface at the connector 32, and the connector 32 is threadedly connected to the end cavity block 31 at the threaded interface. The wire 34 and the high-temperature resistant metal wire 33 are connected by a connecting ring 36, which is engaged within the recess of the connector 32. (Refer to...) Figure 4 and Figure 5 As shown, in an optional embodiment: the high-temperature resistant metal wire 33 passes through the concave opening of the connector 32, and the end cavity block 31 has a through hole. The wire 34 passes through the inner cavity of the end cavity block 31 and exits through the through hole. With this arrangement, when the connector 32 and the end cavity block 31 are threaded together, the high-temperature resistant metal wire 33 will be straightened and tightened.

[0036] The central axis of the through hole in the end cavity block 31 is located on the central axis of the rotating shaft 3. It should be noted that this arrangement prevents the wire 34 located outside the end cavity block 31 from wobbling when the rotating shaft 3 rotates, thus avoiding wear or tangling of the wire 34 due to wobbling. (Refer to...) Figure 3 and Figure 4As shown, the burner 2 is fixedly connected by the fastener 21. It should be noted that the fastener 21 is U-shaped and is fixed to the bottom surface of the top plate 1 by existing screws, thereby pressing the burner 2 against the bottom surface of the top plate 1.

[0037] The working principle of this mechanism is explained through its operation process: When using this mechanism, the rotating shaft 3 is rotated by the pull ring 43 and the short shaft 4 is pushed forward, so that the short shaft 4 extends forward until the limiting end block 41 is placed directly above the limiting pad 42. At this time, the pull ring 43 is released. Under the gravity of the end cavity block 31, the connecting piece 32 and the high temperature resistant metal wire 33, the rotating shaft 3 will rotate until the limiting end block 41 abuts against the limiting pad 42. At this time, the high temperature resistant metal wire 33 is at the front end of several burners 2. Then, the power is connected through the plug 35, and the burners 2 are started to spray gas forward. The high temperature of the high temperature resistant metal wire 33 after being energized will automatically ignite the gas sprayed by the burners 2, thereby completing the ignition operation of the burners 2.

[0038] After the ignition operation of the burner 2 is completed, disconnect the power supply of the plug 35, pull the pull ring 43 backward to control the short shaft 4 to extend backward, and then release the pull ring 43. Under the gravity of the end cavity block 31, the connector 32 and the high-temperature resistant metal wire 33, the rotating shaft 3 will rotate, and the high-temperature resistant metal wire 33 will rotate to the bottom of the top plate 1 to avoid the high-temperature resistant metal wire 33 being burned for a long time, and at the same time to avoid the high-temperature resistant metal wire 33 burning the staff, thereby improving the durability and safety of the mechanism.

[0039] This mechanism, through the arrangement and collaboration of rotating shaft 3, high-temperature resistant metal wire 33, and short shaft 4, utilizes the high temperature of the high-temperature resistant metal wire 33 after being energized to automatically ignite the gas sprayed from the burner 2, achieving rapid and automatic ignition of the burner 2. The short shaft 4 controls the rotation of rotating shaft 3, and in conjunction with the gravity of the high-temperature resistant metal wire 33, connecting piece 32, and end cavity block 31, it achieves convenient positioning of the high-temperature resistant metal wire 33. The mechanism is easy to operate, improves its durability and safety, and has a simple and efficient structure, making it suitable for widespread application in wire drawing and filling machines.

[0040] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
