[0002] As society continues to develop, people's living standards are gradually improving, and dietary concepts are constantly changing. For convenience and time saving, directly edible food and beverages have become an indispensable part of their lives. However, if directly edible beverages are directly exposed to the air, they will cause pollution to the beverages. Most plastic cup beverages will be used with a layer of plastic sealing film on the mouth of the cup. Since most of the current manual plastic cup sealing machines are single-station designs, that is, only a single plastic cup can be placed for processing during a sealing operation, this results in a slow speed when a large number of plastic cups need to be sealed. At this time, a multi-station plastic cup sealing machine is required for use.

[0009] Compared with the prior art, the present invention can achieve the following beneficial effects:

[0010] 1. By placing the plastic cup inside the limiting ring and pushing the placement plate to move below the hot-pressing sealing ring, the rotating handle is turned downward to drive the hot-pressing sealing ring and perform sealing work on the single plastic cup with the sealing film. When multiple plastic cups need to be processed with sealing films, plastic cups are placed inside each limiting ring, and several plastic cups are pushed to the bottom of the corresponding hot-pressing sealing ring. The switch component and the connecting component are coordinated to drive several sealing film transmission cylinders to perform synchronous meshing transmission.

[0011] 2. Place a single plastic cup inside the limiting collar, rotate the screw outside the side plate to disengage it from the outside of the positioning plate, and move the bottom plate to drive the two side slides upward so that the outside of the bottom plate fits with the outside of the plastic cup. Then, rotate the screw outside the side plate toward the positioning plate again. The friction resistance between the screw and the positioning plate fixes the height of the bottom plate, thereby achieving the effect of quickly and stably positioning the plastic cup. At the same time, move the rightmost bottom plate upward to drive the lifting slot so that the lifting plate on the left drives the bottom plate to rise synchronously with the rightmost bottom plate, thereby achieving the effect of synchronously rising multiple bottom plates for multi-station adjustment.

[0012] 3. After the sealing film transmission cylinder is rotated inside the sealing machine body, the sealing film transmission cylinder drives the sealing film to be transmitted inside the packaging groove. At this time, the relative position of the sealing film and the window is observed, so that the sealing film is quickly positioned above the mouth of the plastic cup below the hot-pressing sealing ring, so as to facilitate the user to quickly perform the sealing work.

[0013] 4. By holding the handle to drive the horizontal push plate to move downward, the horizontal push plate drives the short plate and causes the elastic rope to accumulate force and stretch downward inside the moving slot. When the handle is released, the elastic force accumulated by the elastic rope drives the short plate to reset and move upward inside the moving slot, thereby facilitating the reciprocating use of the horizontal push plate.

When the handle 46 is released, the elastic force accumulated by the elastic rope 43 drives the short plate 44 to reset and move upward inside the movable slot 42, thereby facilitating the reciprocating use of the transverse push plate 41.

[0030] Working principle:

[0031] When in use: the first step is to place a single plastic cup inside the limiting ring 16, rotate the screw 56 outside the side table 57 to disengage from the outside of the positioning plate 51, and move the bottom plate 50 to drive the two side slides 55 to move upward so that the outside of the bottom plate 50 fits with the outside of the plastic cup. At this time, rotate the screw 56 outside the side table 57 toward the positioning plate 51 again, and the friction resistance of the contact between the screw 56 and the positioning plate 51 fixes the height of the bottom plate 50, thereby achieving the effect of quickly and stably positioning the plastic cup.

[0032] In the second step, the plastic cup is placed inside the limiting ring 16 and the placing plate 15 is pushed to move to the bottom of the hot pressing sealing ring 18. At this time, the rotating handle 11 is turned downward to drive the hot pressing sealing ring 18 and seal the plastic cup with a sealing film. When it is necessary to process multiple plastic cups with sealing films, plastic cups are placed inside each limiting ring 16 and several plastic cups are pushed to the bottom of the corresponding hot pressing sealing ring 18. At this time, the first transmission gear roller 21 is moved toward the direction of the second transmission gear roller 23. The first transmission gear roller 21 drives the connecting roller 32 and the driving ring 31 drives the vertical plate 35 to move horizontally inside the movable notch 38. The setting of the two guide components assists the second transmission gear roller 23 and the first transmission gear roller 21 to move outside. The inside of the slot 24 performs stable lateral movement, and at the same time, the first transmission gear roller 21 drives the connecting roller 32 and makes the driving ring 31 move and engage into the inside of the slot opening 36. At this time, the second transmission gear roller 23 and the first transmission gear roller 21 synchronously drive the outer rotating rod 27 and the inner rotating rod 28 to make the second driving block 26 and the first driving block 22 move inside the two side grooves 25. The second transmission gear roller 23 and the first transmission gear roller 21 move toward the sealing film transmission cylinder 12 inside the outer slot 24 and mesh with the sealing film transmission cylinder 12. At this time, the second transmission gear roller 23 is rotated to drive the first transmission gear roller 21 and make the several sealing film transmission cylinders 12 meshed with it rotate synchronously, so as to quickly control the rotation of the sealing film of the several sealing film transmission cylinders 12.

[0033] In the third step, by holding the gripping handle 46, the horizontal push plate 41 is driven to move downward outside the external plate 40. The horizontal push plate 41 contacts with the plurality of rotating handles 11 and synchronously drives the plurality of rotating handles 11 to rotate downward, so that the plurality of hot-pressing sealing rings 18 are synchronously moved downward to perform hot-pressing on the sealing film. The plurality of hot-pressing sealing rings 18 perform synchronous and rapid sealing work on the placed plurality of plastic cups, thereby achieving the purpose of facilitating the sealing film processing of a single or multiple plastic cups by the device.

[0034] The embodiments of the present invention are described in detail above with reference to the accompanying drawings, but the present invention is not limited thereto, and various changes can be made within the knowledge scope of technicians in the relevant technical field without departing from the purpose of the present invention.
