[0032] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0033] See also Figure 1 to Figure 7 In the embodiment of the utility model, a hot melt butyl sealant fully automatic filling device includes a filling machine body 1, a No. 1 support seat 2 is installed at the bottom end of the filling machine body 1, a connecting plate 3 protruding outward is integrally formed in the middle section of the vertical plate portion of the No. 1 support seat 2, a receiving groove is opened at the top of the connecting plate 3, and a lifting seat 4 for placing the container is accommodated on the inner wall of the receiving groove;

[0034] Two telescopic support mechanisms for supporting two lifting seats 4 are installed on the top of the horizontal plate portion of the first support seat 2;

[0035] A reciprocating drive mechanism is installed between the two telescopic support mechanisms, and the reciprocating drive mechanism is used to drive the two support telescopic mechanisms to extend and retract alternately;

[0036] The reciprocating drive mechanism comprises: a first drive unit, a second drive unit and a power unit;

[0037] The power unit is used to drive the No. 1 drive unit and the No. 2 drive unit to respectively drive the two supporting telescopic mechanisms to move.

[0038] In this embodiment: when filling the sealant, two containers are placed on the tops of the two lifting seats 4 respectively, and then the power unit is started, and the power unit drives the No. 1 drive unit and the No. 2 drive unit to reciprocate, and the No. 1 drive unit and the No. 2 drive unit rotate from top to bottom toward the No. 2 gear block 15. At this time, the No. 1 drive unit drives the lifting seat 4 located above the No. 1 gear block 16 to move upward, while the No. 2 drive unit cannot drive the lifting seat 4 located above the No. 2 gear block 15 to move, and the lifting seat 4 located above the No. 2 gear block 15 remains stationary;

[0039] When the container located above the No. 1 gear block 16 is filled with sealant, the power unit is started to rotate in the opposite direction, that is, the No. 1 drive unit and the No. 2 drive unit rotate from bottom to top toward the No. 2 gear block 15. At this time, the No. 1 drive mechanism drives the sealant container located above the No. 1 gear block 16 to descend, and at the same time, the No. 2 drive unit drives the lifting seat 4 located above the No. 2 gear block 15 to move upward to perform the glue filling operation;

[0040] When the machine is about to stop, that is, no container is placed on the top of the two lifting seats 4 for glue pouring. When the lifting seat 4 located above the No. 1 gear block 16 drives the container to rise, the container is no longer placed on the lifting seat 4 above the No. 1 gear block 16. When the lifting seat 4 rises to the highest position, the power unit continues to drive the rotating gear 13 to rotate. At this time, the rotating gear 13 is misaligned with the No. 1 gear block 16. At this time, the lifting plate 12 connected to the No. 1 gear block 16 moves downward under the action of gravity, and the rotating gear 13 rotates 360 degrees to reset to the initial position.

[0041] Please refer to Figure 1 , Figure 2 and Figure 7 The supporting telescopic mechanism includes a slide post 5 fixedly connected to the four corners of the bottom end of the lifting seat 4, the slide post 5 passes through the connecting plate 3, and is connected to the connecting plate 3 by sliding up and down;

[0042] The outer wall of the sliding column 5 is provided with a sleeve 6 fixedly connected to the top of the horizontal plate portion of the No. 1 support seat 2, and the outer wall of the sliding column 5 is slidably connected to the inner wall of the sleeve 6 up and down;

[0043] The outer walls of the four sliding columns 5 in one group are fixedly connected to the annular portions at the four corners of the I-shaped frame 7 , and the sides of the two groups of I-shaped frames 7 close to each other are fixedly connected with the lifting plates 12 .

[0044] In this embodiment, during the up and down movement of the two lifting seats 4 , the lifting seats 4 drive the slide post 5 to move up and down on the inner wall of the sleeve 6 , and the sleeve 6 cooperates with the slide post 5 to guide the up and down movement of the lifting seats 4 .

[0045] Please refer to Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 and Figure 7 The first drive unit includes a first gear block 16 formed on the inner side of a lifting plate 12, the outer wall of the first gear block 16 is meshed with a rotating gear 13, and the gear blocks on the outer periphery of the rotating gear 13 are evenly spaced at 180 degrees;

[0046] The second driving mechanism includes a second gear block 15 formed on the inner side of another lifting plate 12, and a one-way gear 14 is arranged on the inner side of the lifting plate 12. The outer periphery of the one-way gear 14 is circumferentially equidistantly connected with a plurality of one-way gear blocks 17;

[0047] The rotating end of the one-way gear block 17 is formed with a rotating shaft 18 rotatably connected to the one-way gear 14, and the one-way gear 14 is provided with an arc groove 19, which is located outside the rotating shaft 18, and the rotating end of the one-way gear block 17 is formed with a movable rod 20 movably connected to the arc groove 19;

[0048] There is a gap between the rotating end of the one-way gear block 17 and the end surface of the one-way gear 14, and a torsion spring 21 fixed to the end surface of the one-way gear 14 and the inner side of the one-way gear block 17 is arranged in the gap;

[0049] The one-way gear 14 and the rotating gear 13 are misaligned in the front-to-back direction;

[0050] The center of the arc groove 19 coincides with the center of the rotating shaft 18 , and the torsion spring 21 is located on the outer periphery of the rotating shaft 18 .

[0051] In this embodiment, when the power unit drives the first drive unit and the second drive unit to rotate from top to bottom toward the second gear block 15, the gear blocks distributed at 180 degrees on the outer side of the rotating gear 13 are located in the lower half of the outer periphery of the gear (e.g. Figure 5 As shown), the rotation of the rotating gear 13 can drive the lifting plate 12 connected to the first gear block 16 to move upward through the first gear block 16, and the lifting plate 12 can drive the four slide posts 5 in a group to move upward through the I-beam frame 7, and the slide posts 5 can drive the lifting seat 4 to move upward until the rotating gear 13 rotates 180 degrees, at which time the lifting seat 4 moves to the highest position;

[0052] When rotating in this direction, the one-way gear 14 also rotates synchronously and in the same direction. When the one-way gear 14 drives the one-way tooth block 17 to rotate in this direction, the reaction force generated by the contact between the one-way tooth block 17 and the second tooth block 15 causes the one-way tooth block 17 to drive the movable rod 20 to rotate from top to bottom in the arc groove 19. At the same time, the one-way tooth block 17 rotates upward with the rotating shaft 18 as the axis. At this time, the torsion spring 21 is twisted, so the second driving unit cannot drive the lifting seat 4 above it to move upward;

[0053] When the lifting seat 4 and the container above the No. 1 driving unit are filled, the power unit rotates in the opposite direction, and the rotating gear 13 rotates from bottom to top toward the No. 2 gear block 15, and the rotating gear 13 can drive the lifting plate 12 connected thereto to move downward through the No. 1 gear block 16;

[0054] At the same time, the one-way gear 14 drives the one-way gear block 17 to apply a squeezing force to the bottom end of the No. 2 gear block 15, and at this time the movable rod 20 is stuck at the top of the arc groove 19, so the one-way gear block 17 cannot rotate, and the one-way gear block 17 can drive the lifting plate 12 connected to the No. 2 gear block 15 upward through the No. 2 gear block 15, and the lifting plate 12 can drive the lifting seat 4 and its container above it to move upward for penetration. When the No. 1 driving unit is reset, the lifting seat 4 and its container above the No. 2 driving unit are lifted to the top. When the lifting seat 4 above the No. 2 driving unit completes the filling, the power unit reverses again. At this time, the No. 1 driving unit can drive the lifting plate 12 connected to the No. 1 gear block 16 to move upward, and at this time, the lifting plate 12 connected to the No. 2 gear block 15 is gradually lowered under the rotation of the one-way gear 14. When the lifting seat 4 and the container above the No. 1 driving mechanism reach the highest position, the lifting seat 4 and the container above the No. 2 driving mechanism are lowered to the initial position.

[0055] When the sealant filling is completed or continuous production is not required in other situations, the container is no longer placed above the two lifting seats 4. At this time, when the lifting seat 4 above the No. 2 driving mechanism moves downward from the highest position and moves to the lowest position, the lifting seat 4 above the No. 1 driving unit moves to the highest position. At this time, the power unit continues to rotate. At this time, the rotating gear 13 is misaligned with the No. 1 gear block 16. Under the action of gravity, the lifting plate 12 connected to the No. 1 gear block 16 and the lifting seat 4 above it drive the screw slide column 5 in the group to move downward along the inner wall of the sleeve 6. At this time, the buffer unit in the lifting mechanism of this group buffers the descending slide column 5 to avoid the safety risk caused by too fast downward impact.

[0056] Please refer to Figure 2 The power unit includes two No. 2 support seats 8 fixedly connected to the transverse plate portion of the No. 1 support seat 2, and a stepper motor 9 is installed on one transverse plate portion through a mounting bracket. The output end of the stepper motor 9 passes through the mounting bracket and is connected to a worm 10. The output end of the stepper motor 9 is rotatably connected to the mounting bracket. A worm gear 11 is meshed on the outer periphery of the worm 10. One end of the worm gear 11 is connected to a synchronous shaft rotatably connected to the two No. 2 support seats 8. A rotating gear 13 and a one-way gear 14 are interference fitted on the outer wall of the one-way gear 14.

[0057] In this embodiment: during the operation of the stepper motor 9, the worm 10 rotates along with the output end of the stepper motor 9, and the rotation of the worm 10 drives the worm wheel 11 to rotate. Since the transmission between the worm 10 and the worm wheel 11 is self-locking, the reversal problem of the stepper motor 9 caused by gravity can be prevented.

[0058] Please refer to Figure 7 , a buffer unit is provided on the telescopic mechanism connected to the first driving unit;

[0059] The buffer unit includes an input pipe 23 and an output pipe 24 symmetrically arranged at the bottom end of the outer wall of the sleeve 6. A one-way air inlet valve is installed on the input pipe 23, and a one-way air outlet valve is installed on the output pipe 24. An air hole 22 is opened on the top plate of the sleeve 6.

[0060] In this embodiment: after the rotating gear 13 rotates 180 degrees and then continues to rotate, the lifting seat 4 above the No. 1 driving unit is caused to descend under the action of gravity. At this time, the piston at the bottom end of the slide column 5 squeezes the space inside the sleeve 6, and the squeezed air can only be discharged through the output pipe 24. The discharge area is small, so the slide column 5 descending under the action of gravity can be buffered to prevent it from falling too quickly;

[0061] It should be noted that when the power unit is driven to operate, the action of the sliding column 5 has additional pressure, which can apply additional pressure to the air in the sleeve 6 to promote the air discharge speed, thus not affecting the normal operation of the device.

[0062] What is described above is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
