DETAILED DESCRIPTION

[0033] The embodiment and the working principle of the present application are described below in detail with reference to the drawings. A heat shrinkage machine comprises a disposable cup conveying mechanism, which comprises a conveying part 2 and a shaping part 1. The conveying part 2 is longitudinally conveyed and comprises a left transmission chain 21, a right transmission chain 22 and a plurality of cup supporting pieces 25. The left transmission chain 21 and the right transmission chain 22 are arranged on a left sprocket 23 and a right sprocket 24 respectively, and the left sprocket 23 and the right sprocket 24 rotate synchronously. The cup supporting pieces 25 are arranged transversely and connected to the left transmission chain 21 and the right transmission chain 22 at both ends respectively. The plurality of cup supporting pieces 25 are evenly distributed on the left transmission chain 21 and the right transmission chain 22. The rotation of the left sprocket 23 and the right sprocket 24 drives the left transmission chain 21 and the right transmission chain 22 to move, so that the cup supporting pieces 25 move along the left transmission chain 21 and the right transmission chain 22. The upper section of the left transmission chain 21 and the right transmission chain 22 is a conveying section. The disposable cup is conveyed from the feeding end to the discharging end in the cup supporting piece 25 of the conveying section. The shaping part 1 comprises a plurality of shaping groups. One cup supporting piece 25 is provided with one shaping group. Each shaping group comprises a cup blocking piece 15 and a top cup piece 14 arranged on the cup supporting piece 25. The top cup piece 14 moves transversely relative to the cup blocking piece 15 and extends into the cup. The disposable cup is arranged between the cup blocking piece 15 and the top cup piece 14 on the cup supporting piece 25 with the cup opening facing the top cup piece 14. During the conveying process, the top cup piece 14 moves towards the cup, and the cup blocking piece 15 blocks the bottom of the cup. The top cup piece 14 extends into the cup, so that the film of the cup opening enters the cup and adheres to the inner wall of the cup body. The disposable cup enters the heat shrinkage furnace 3, the film shrinks to wrap the cup body, and the cavity of the cup opening is retained. The disposable cup 5 after heat shrinkage molding has a cup opening cavity, which can be stacked together during collection, facilitating the stacking of the cups. The top cup piece 14 comprises a top cup head, which matches the inner cavity of the cup body. The top cup head extends into the cup, so that the film wrapped outside the cup body enters the cup and adheres to the inner wall of the cup body, improving the packaging effect. The conveying part 2 longitudinally penetrates the heat shrinkage furnace 3. In the heat shrinkage furnace 3, the top cup piece 14 remains in the cup body. When the film is heat shrunk, it is limited by the top cup piece 14. The heat shrunk film is in the shape of the inner cavity of the cup body and adheres to the inner wall of the cup body tightly, achieving good molding effect.

[0034] The shaping component 1 also includes a first guide rail 11 and a second guide rail 12. The first guide rail 11 and the second guide rail 12 are longitudinally arranged on the frame. The top cup 14 is slidably arranged on the first guide rail 11, and the cup stop 15 is slidably arranged on the second guide rail 12, so that the top cup 14 and the cup stop 15 move stably. If the top cup 14 is driven by a separate driving component to move laterally, not only will the processing cost be high, but the installation of the driving component will also be difficult and the driving stability will be poor. To solve the above problems, in the material conveying path, the first guide rail 11 includes an insertion section, an insertion holding section, and an exit section in sequence, and the second guide rail 12 is arranged in a straight line. As the cup support 25 moves forward, the top cup 14 passes through the insertion section, the insertion holding section, and the exit section in sequence along the first guide rail 11. The top cup 14 can move laterally relative to the cup stop 15 without additional power, so that the top cup 14 can enter and exit the cup opening. The insertion section, where the top cup 14 approaches the cup stop 15, involves the top cup 14 gradually moving towards the cup stop 15 as the disposable cup enters the cup holder 25 until it enters the cup. The insertion holding section maintains the lateral position of the top cup pin and the cup stop 15 after the top cup 14 enters the cup, keeping the top cup 14 in the inserted state. The withdrawal section moves the top cup 14 away from the cup stop 15 and exits the cup opening, allowing the disposable cup to be discharged from the outlet without being restricted by the top cup 14. The insertion and withdrawal sections are inclined, while the insertion holding section is a straight section. The distance between the top cup 14 and the cup stop 15 is minimal. An withdrawal holding section can be installed from the end of the withdrawal section to the beginning of the insertion section, where the distance between the top cup 14 and the cup stop 15 is maximized for the disposable cup's entry and exit from the cup holder 25. (See attached image) Figure 2 The extension section extends from outside the heat shrink oven to inside the heat shrink oven, the extension holding section is inside the heat shrink oven, and the withdrawal section extends from inside the heat shrink oven to outside the heat shrink oven. After entering the heat shrink oven, the top cup component completes the extension. During heat shrinking, the top cup component 14 is held inside the cup film for heat shrinking. This structure is compact and has a good heat shrinking effect. The heat-shrinked film is shaped like the inner cavity of the cup and remains compact and fits the inner wall of the cup.

[0035] The number of disposable cup sets is different, the height of the cup body is different, and the length of the stacked cup is also different. The shaping part 1 comprises an adjusting assembly for adjusting the distance between the cup blocking part 15 and the cup top part 14. The distance between the cup blocking part 15 and the cup top part 14 is adjusted by the adjusting assembly to adapt to disposable cups of different lengths. The adjusting assembly comprises a third guide rail 13, which is transversely arranged on the rack. The second guide rail 12 is slidably arranged on the third guide rail 13. Moving the second guide rail 12 transversely moves the cup blocking part 15 transversely on the rack, thereby adjusting the distance between the cup blocking part 15 and the cup top part 14. The adjusting assembly further comprises an adjusting screw 16 and a nut. The adjusting screw 16 is transversely rotatably arranged on the rack. The nut is installed on the second guide rail 12. The adjusting screw 16 and the nut are provided in two sets. The adjusting screw 16 is provided with a synchronous wheel 17. Two synchronous wheels 17 are provided with a synchronous belt 18. Rotating one adjusting screw 16 synchronously rotates the two adjusting screws 16, which stably moves the second guide rail 12 transversely on the third guide rail 13, quickly and accurately adjusts the distance between the cup blocking part 15 and the cup top part 14.

[0036] The cup supporting part 25 comprises a first cross bar 251 and a second cross bar 252, and has a material supporting gap between the first cross bar 251 and the second cross bar 252. The cup body is placed on the first cross bar 251 and the second cross bar 252, and is supported by the two cross bars. Adjacent cup supporting parts 25 are also provided with a separation part 26, which is installed on the cup supporting part 25. The separation part 26 not only plays a role in blocking material, but also separates adjacent cup bodies, so that each group of cups has independent space and is not disturbed by other groups. The separation part 26 is larger at the top and smaller at the bottom, and the cavity between adjacent separation parts 26 is inverted trapezoidal. In this way, the entrance of the cup supporting part 25 is relatively larger, which is beneficial to the entry and discharge of disposable cups.

[0037] The beginning end of the conveying component 2 is connected with a cup pushing component 4, which comprises a pushing plate 41 for pushing the material longitudinally. The pushing plate 41 pushes the incoming material to the cup supporting part 25 of the conveying component 2, so as to automatically push the disposable cup 5. The cup pushing component 4 further comprises a supporting plate 44, which is not lower than the conveying component 2, and the pushing plate 41 is arranged above the supporting plate 44. The supporting plate 44 supports the disposable cup 5, and the pushing plate 41 pushes the disposable cup 5 on the supporting plate 44 to leave the supporting plate 44 and enter the cup supporting part 25 of the conveying component 2. The pushing plate 41 is arranged in several and uniformly installed on the annular transmission belt 43, which is longitudinally intermittently driven. The pushing plate 41 is arranged transversely, and the material cavity 42 is arranged between the adjacent pushing plates 41. The transmission belt 43 drives the pushing plate 41 to move, and the pushing plate 41 pushes the disposable cup to move longitudinally. The longitudinal pushing section of the transmission belt 43 is provided with at least two stations, which are the feeding station and the discharging station. The feeding station is provided with a transversely conveying conveying belt 45, which is arranged below the pushing plate 41 and connected with the supporting plate 44. As shown in the drawings, the disposable cup is horizontally transversely nested and arranged on the conveying belt 45. When the disposable cup enters the feeding station transversely, the transmission belt 43 stops conveying, and the material cavity 42 is opposite to the conveying belt 45 to receive the disposable cup 5. After the disposable cup enters the material cavity 42 of the feeding station, the transmission belt 43 is driven, and the pushing plate 41 pushes the disposable cup on the conveying belt 45 to the supporting plate 44. The transmission belt 43 is driven once, a new group of disposable cups 5 is received, and the last group of disposable cups 5 is pushed to move one position. The pushing plate 41 of the discharging station pushes the cup to leave the supporting plate 44 and enter the cup supporting part 25. The material cavity 42 is matched with the outer diameter of the cup body, which is better, so as to avoid the shaking of the material during the forward movement, and improve the precision and stability of the feeding.

[0038] The working principle of the preferred embodiment is further illustrated below with reference to the drawings: the finished thin film packaged disposable cup 5 is sent to the conveying belt 45, at this time the disposable cup 5 is packaged by the thin film and placed horizontally on the conveying belt 45, the conveying belt 45 conveys it horizontally to the material cavity 42 of the feeding station, the transmission belt 43 drives, the push plate 41 pushes the disposable cup 5 of the feeding station to move forward until the disposable cup 5 enters the discharging station, the push plate 41 pushes it out, the disposable cup 5 falls on the cup supporting member 25 at the feeding end and is placed between the cup blocking member 15 and the cup lifting member 14, with the driving of the left transmission chain 21 and the right transmission chain 22, the cup supporting member 25 moves at the discharging end and passes through the heat shrinkage furnace 3, the cup lifting member 14 enters the extension section from the exit holding section, with the forward movement of the cup supporting member 25, the cup lifting member 14 moves gradually to the cup blocking member 15 along the first guide rail 11 in the extension section and enters the cup body, pushes the thin film at the cup mouth into the cup and makes the thin film adhere to the inner wall of the cup body; then enters the extension holding section, the cup lifting member 14 keeps the extension state, the thin film shrinks under the heating of the heat shrinkage furnace 3, wraps the cup body and covers the inner wall of the cup body; then enters the exit section, the cup lifting member 14 gradually moves away from the cup blocking member 15 along the first guide rail 11, the distance between them gradually increases, finally the cup lifting member 14 enters the exit holding section and keeps the distance from the cup blocking member 15, the disposable cup after heat shrinkage is sent to the discharging end, which is the end of the conveying component 2, at this time the two ends of the disposable cup are not limited, the disposable cup is separated from the cup supporting member.
