[0033] Specifically, when the cup holder 3 is placed in the cup holder positioning frame 207, the cup holder positioning frame 207 is retracted by the control telescopic cylinder 205 of the control platform 8, so that the cup holder 3 is placed below the heat sealing mechanism 4, after the heat sealing mechanism 4 is extruded and heat sealed, the cup holder positioning frame 207 is pushed out by the control telescopic cylinder 205 of the control platform 8, and the cup holder 3 is pushed out by the control ejector cylinder 203 of the control platform 8, that is, one heat sealing process is completed.

[0034] The cup holder 3 comprises a cup holder plate 31, four diagonal feet 32 with non-slip pads welded below the cup holder plate 31, six cup holder openings 33 for fixing the cups equidistantly opened on the cup holder plate 31, and an annular groove 34 for collecting scattered mica powder opened on the periphery of the cup holder opening 33.

[0035] The heat sealing mechanism 4 comprises a vertical drive cylinder 41 fixedly installed with the rack 1, a fixed plate 42 fixedly installed at the lower end of the vertical drive cylinder 41, a first lower pressing plate 43 located below the fixed plate 42 and fixedly installed with the output end of the vertical drive cylinder 41, six heat sealing heads 44 equidistantly installed below the first lower pressing plate 43, an auxiliary plate 45 fixedly installed with the first lower pressing plate 43 for guiding the heat sealing heads 44, and a second pressing plate 46 assembled with the auxiliary plate 45. Specifically, the vertical drive cylinder 41 is fixedly installed with the support plate 18.

[0036] The two ends of the first lower pressing plate 43 are welded with guide columns 431 penetrating through the fixed plate 42, the first lower pressing plate 43 is provided with six threading holes 432 corresponding to the positions of the heat sealing heads 44, and the first lower pressing plate 43 is provided with three first stud through holes 432 around each threading hole 432;

[0037] The upper end of the heat sealing head 44 is screwed with three first studs 441, and the lower end of the first stud 441 is sleeved with a first stud spring 442. Specifically, the three first studs 441 pass through the three first stud through holes 432 on the first lower pressing plate 43, are sleeved with the first stud spring 442, and are finally screwed into the heat sealing head 44, so that the heat sealing head 44 can be suspended and installed through the first lower pressing plate 43;

[0041] Six through holes 461 are formed in the second pressing plate 46, which are convenient for the hot sealing head 44 to move during the hot sealing process.

[0042] Six threaded holes 453 are formed in the periphery of the second pressing plate 46, which are convenient for the second threaded rod 453 to pass through the through hole 452 of the auxiliary plate 45, and then be screwed into the threaded hole 453, so that the second pressing plate 46 can be installed on the auxiliary plate 45.

[0043] It should be further explained that in the initial state, the vertical driving cylinder 41 is in the contracted state, the first lower pressing plate 43 is located at the highest position, the hot sealing head 44 is suspended below the first lower pressing plate 43 by the first threaded rod spring 442, and the spring is in the natural length. In the pressing stage, the vertical driving cylinder 41 is started to push the first lower pressing plate 43 to move downward along the guide column 431, and the hot sealing head 44 first contacts the surface of the cup holder 3. The vertical driving cylinder 41 continues to press, the first threaded rod spring 442 is compressed to form the first stage of buffering, and the height of each sealing head is self-adaptively adjusted according to the contact resistance to ensure uniform distribution of pressure. The through hole 452 of the auxiliary plate 45 limits the horizontal deviation of the hot sealing head 44 to maintain the alignment accuracy. With the increase of the pressing force, the second pressing plate 46 contacts the cup holder 3, and the second threaded rod spring 454 starts to compress to form the second stage of buffering, further absorbing the impact and avoiding overload. In the hot sealing process, the hot sealing head 44 is heated by electricity, and the heat energy is transmitted through the wire connected through the wire hole 432. Under constant pressure, the sealing head melts and seals the cup holder 3. In the reset stage, the vertical driving cylinder 41 is pulled back, and the first lower pressing plate 43 rises. At this time, the first threaded rod spring 442 and the second threaded rod spring 454 release the stored elastic potential energy to push the hot sealing head 44 and the second pressing plate 46 to reset and separate from the cup holder 3. The guide column 431 ensures that the first lower pressing plate 43 rises vertically to avoid deflection and prepare for the next operation.

[0044] The film unwinding mechanism 6 comprises an L-shaped support 61, two steel columns 62 fixedly installed on the L-shaped support 61 through bolts, a rotary cylinder 63 installed below the two steel columns 62, and a film unwinding wheel 64 installed on the output end of the rotary cylinder 63 and used for abutting against the hot sealing film 5. Specifically, the L-shaped support 61 is fixedly installed on the first bracket 12.

[0045] The winding mechanism 7 comprises a winding frame 71, a winding motor 73 arranged on one side of the winding frame 71 and driving the winding frame 71 to rotate. Specifically, the winding frame 71 and the winding motor 73 are both installed on the second bracket 13.

[0046] It needs to be further explained that the heat-sealing adhesive tape is discharged from the heat-sealing adhesive roll 5, is pressed by the pressing guide roller 14 in turn, is supported and guided by the supporting guide roller 15, is guided by the first side guide roller 16, passes through the gap between the placing pulling mechanism 2 and the heat-sealing mechanism 4, is guided by the second side guide roller 17, and is finally wound up by the winding frame 71. The heat-sealing adhesive tape wound up by the winding frame 71 is the residual heat-sealing adhesive tape after heat-sealing.
