[0045] The assembly sealing machine of the utility model relies on the clearance matching structure between the beam mold 130 and the mounting hole 111 of the multi-station turntable 110, the zero clearance matching structure between the beam mold 130 and the limit ring 140, and the beam mechanism 200 with adjustable beam axis position, and / or the sealing mechanism 300 with adjustable sealing axis position, firstly adjusts the position of the first beam mold 130 to form the first beam mold, and then adjusts the position of the waist axis of the waist mechanism 200 and / or the sealing axis of the sealing mechanism 300 according to the central axis of the first beam mold, and then adjusts the position of the waist axis of the waist mechanism 200 and / or the sealing axis of the sealing mechanism 300 according to the central axis of the first beam mold, and then adjusts the position of the waist axis of the waist mechanism 200 and / or the sealing axis of the sealing mechanism 300 according to the central axis of the waist mechanism 200 The sealing axis adjusts the position of the central axes of other beam modes 130, and finally realizes that the central axis of the first beam mode 130 is used as a reference to calibrate the central axes of other beam modes 130, so that the central axes of all beam modes 130 are located on the same circumference of the multi-station turntable 110, and each limiting ring 140 is used to limit the corresponding beam mode 130, so that when the beam mode 130 is replaced later, the limiting effect of the limiting ring 140 can be utilized to directly make the central axis of the new beam mode 130 can be maintained on the same circumference of the multi-station turntable 110 without the need to calibrate the position of the new beam mode 130.

[0046] Specifically, the steps of calibrating the position of each beam mold 130 by the assembly sealing machine are as follows:

[0047] Step 100: placing each beam mold 130 in the corresponding mounting hole 111 on the multi-station turntable 110;

[0052] Step 600 : sleeve each limiting ring 140 on the outer periphery of the corresponding beam mold 130 , and connect and fix each limiting ring 140 to the multi-station turntable 110 .

[0053] When replacing the beam mold 130, first remove the old beam mold 130 from the multi-station turntable 110, and then place the new beam mold 130 in the corresponding mounting hole 111 on the multi-station turntable 110, so that the new beam mold 130 passes through the corresponding limiting ring 140, and then the new beam mold 130 is connected and fixed to the multi-station turntable 110.

[0054] In this embodiment, the waist-binding axis of the waist-binding mechanism 200 and the sealing axis of the sealing mechanism 300 are both position-adjustable.

[0057] If the first fine-tuning screw 233 is rotationally engaged with the first connecting member 231 and is threadedly screwed with the second connecting member 232, then when the first fine-tuning screw 233 is rotated, since the first fine-tuning screw 233 is rotationally engaged with the first connecting member 231, the first fine-tuning screw 233 will not drive the first connecting member 231 to move, and since the first fine-tuning screw 233 is threadedly screwed with the second connecting member 232, the first fine-tuning screw 233 will drive the second connecting member 232 to move under the action of the thread; if the first fine-tuning screw 233 is threadedly screwed with the first connecting member 231 and is rotationally engaged with the second connecting member 232, then when the first fine-tuning screw 233 is rotated, since The first fine-tuning screw 233 is rotationally engaged with the second connecting member 232, and the first fine-tuning screw 233 will not drive the second connecting member 232 to move. However, since the first fine-tuning screw 233 is threadedly engaged with the first connecting member 231, the first fine-tuning screw 233 will drive the first connecting member 231 to move under the action of the thread; that is, by rotating the first fine-tuning screw 233 of the two waist wheel fine-tuning structures 230, the positions of the first waist wheel 210 and the second waist wheel 220 can be adjusted respectively, thereby not only adjusting the distance between the first waist wheel 210 and the second waist wheel 220, but also adjusting the position of the waist axis (symmetry axis) between the first waist wheel 210 and the second waist wheel 220.

[0059] The sealing wheel adjustment bracket includes two sealing wheel fine-tuning structures 330, which respectively connect and install the first sealing wheel 310 and the second sealing wheel 320 on the sealing motion assembly 340; the sealing wheel fine-tuning structure 330 includes a third connecting member 331 rotatably connected to the first sealing wheel 310 or the second sealing wheel 320, a fourth connecting member 332 fixedly connected to the sealing motion assembly 340, and a second fine-tuning screw 333 connected between the third connecting member 331 and the fourth connecting member 332, the second fine-tuning screw 333 is rotationally clamped with one of the third connecting member 331 and the fourth connecting member 332, and is threadedly screwed with the other of the third connecting member 331 and the fourth connecting member 332.

[0060] If the second fine-tuning screw 333 is rotationally engaged with the third connecting member 331 and is threadedly screwed with the fourth connecting member 332, then when the second fine-tuning screw 333 is rotated, since the second fine-tuning screw 333 is rotationally engaged with the third connecting member 331, the second fine-tuning screw 333 will not drive the third connecting member 331 to move, and since the second fine-tuning screw 333 is threadedly screwed with the fourth connecting member 332, the second fine-tuning screw will drive the fourth connecting member 332 to move under the action of the thread; if the second fine-tuning screw 333 is threadedly screwed with the third connecting member 331 and is rotationally engaged with the fourth connecting member 332, then when the second fine-tuning screw 333 is rotated, since the The second fine-tuning screw 333 is rotatably engaged with the fourth connecting member 332, and the second fine-tuning screw 333 will not drive the fourth connecting member 332 to move. Since the second fine-tuning screw 333 is threadedly engaged with the third connecting member 331, the second fine-tuning screw 333 will drive the third connecting member 331 to move under the action of the thread; that is, by rotating the second fine-tuning screws 333 of the two sealing wheel fine-tuning structures 330, the positions of the first sealing wheel 310 and the second sealing wheel 320 can be adjusted respectively, thereby not only adjusting the distance between the first sealing wheel 310 and the second sealing wheel 320, but also adjusting the position of the sealing axis (symmetry axis) between the first sealing wheel 310 and the second sealing wheel 320.
