[0005] The cup is placed on the cup supporting member of the conveying component and is conveyed in the discharging direction driven by the left and right transmission chains. During the conveying process, the cup-pushing member moves toward the cup, and the cup-blocking member blocks the cup. The cup-pushing member extends into the cup, so that the film at the cup mouth enters the cup and fits the inner wall of the cup body.

[0024] The following describes the details and working principle of the embodiments and examples of the present invention in conjunction with the accompanying drawings. A heat shrinking machine includes a disposable cup conveying mechanism, the disposable cup conveying mechanism includes a conveying component 2 and a shaping component 1, the conveying component 2 conveys longitudinally, the conveying component 2 includes a left transmission chain 21, a right transmission chain 22 and a plurality of cup supporting parts 25, the left transmission chain 21 and the right transmission chain 22 are respectively arranged on a left sprocket 23 and a right sprocket 24, and the left sprocket 23 and the right sprocket 24 rotate synchronously. The cup support member 25 is arranged horizontally, and the two ends of the cup support member 25 are connected to the left transmission chain 21 and the right transmission chain 22 respectively. A plurality of cup support members 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 drive, so that the cup support member 25 moves cyclically with 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 the conveying section. The disposable cup enters the cup support member 25 of the conveying section and is conveyed from the feeding end to the discharging end. The shaping component 1 includes a plurality of shaping groups. One cup support member 25 is installed with a group of shaping groups. Each shaping group includes a cup stopper 15 and a cup top member 14 installed on the cup support member 25. The cup top member 14 moves horizontally relative to the cup stopper 15 and extends into the cup. The disposable cup is placed between the cup blocking member 15 and the cup top member 14 on the cup support member 25, and the cup mouth faces the cup top member 14. During the conveying process, the cup top member 14 moves toward the cup, and the cup blocking member 15 blocks the bottom of the cup. The cup top member 14 extends into the cup, so that the film at the cup mouth enters the cup and fits the inner wall of the cup. In this way, when entering the heat shrink furnace 3, the film shrinks and wraps the cup body, and the cavity at the cup mouth is retained. The disposable cup 5 after heat shrinkage has a cup mouth cavity, which can be stacked together when collected, which is conducive to the stacking of cups. The cup top member 14 includes a cup top head, which matches the inner cavity of the cup body. The cup top head enters the cup, so that the film on the outside of the cup enters the cup and fits the inner wall of the cup body, thereby improving the packaging effect. The conveying component 2 passes through the heat shrinking furnace 3 longitudinally. In the heat shrinking furnace 3, the top cup component 14 is maintained in the cup body, so that the film will be restricted by the top cup component 14 when heat shrinking. The film after heat shrinkage is in the shape of the inner cavity of the cup body, and remains compact and fitted with the inner wall of the cup body, with a good molding effect.

[0025] The shaping component 1 also includes a first guide rail 11 and a second guide rail 12, which are longitudinally arranged on the frame, the top cup member 14 is slidably arranged on the first guide rail 11, and the cup-blocking member 15 is slidably arranged on the second guide rail 12, so that the top cup member 14 and the cup-blocking member 15 can move stably. If a driving member is additionally arranged on the top cup member 14 to drive its lateral movement, not only the processing cost is high, but also there are problems such as the difficulty in installing the driving member and poor driving stability. In order to solve the above problems, on 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-supporting member 25 moves forward, the top cup member 14 passes through the insertion section, the insertion holding section, and the exit section in sequence along the first guide rail 11, and the top cup member 14 can be moved laterally relative to the cup-blocking member 15 without additional power, so that the top cup member 14 can enter and exit the cup mouth. The extending section, i.e. the cup-lifting member 14, approaches the cup-blocking member 15, and when the disposable cup enters the cup-supporting member 25, the cup-lifting member 14 gradually moves toward the cup-blocking member 15 until it enters the cup; the extending and holding section, i.e. after the cup-lifting member 14 extends into the cup, the lateral positions of the cup-lifting needle and the cup-blocking member 15 remain unchanged, and the cup-lifting member 14 remains in the extending state; the withdrawing section, i.e. the cup-lifting member 14 moves away from the cup-blocking member 15 and withdraws from the cup mouth, and the disposable cup is not restricted by the cup-lifting member 14 and can be discharged from the discharging end. The extending section and the withdrawing section are inclined sections, and the extending and holding section is a straight section. The distance between the cup-lifting member 14 and the cup-blocking member 15 is the smallest. An withdrawing and holding section can be set from the end of the withdrawing section to the beginning of the extending section. The distance between the cup-lifting member 14 and the cup-blocking member 15 is the largest, and is used for the disposable cup to enter and exit the cup-supporting member 25. See attached. Figure 2 The extension section extends from outside the heat shrinking furnace to inside the heat shrinking furnace, the extension holding section is inside the heat shrinking furnace, and the exit section extends from inside the heat shrinking furnace to outside the heat shrinking furnace. After entering the heat shrinking furnace, the top cup member completes the extension. During heat shrinkage, the top cup member 14 holds the film inside the cup for heat shrinkage. This structure is compactly arranged and has a good heat shrinkage effect. After heat shrinkage, the film is in the shape of the inner cavity of the cup body and remains compact and fitted with the inner wall of the cup body.

[0026] The length of the stacked disposable cups will be different if the number of stacked disposable cups and the height of the cup bodies are different. The shaping component 1 includes an adjustment component for adjusting the distance between the cup-stopping member 15 and the cup-topping member 14. The distance between the cup-stopping member 15 and the cup-topping member 14 is adjusted by the adjustment component to adapt to disposable cups of different lengths. The adjustment component includes a third guide rail 13, which is transversely arranged on the frame, and the second guide rail 12 is slidably arranged on the third guide rail 13. Transversely moving the second guide rail 12 means moving the cup-stopping member 15 transversely on the frame, thereby adjusting the distance between the cup-stopping member 15 and the cup-topping member 14. The adjustment assembly also includes an adjusting screw 16 and a nut. The adjusting screw 16 is arranged on the frame for transverse rotation. The nut is installed on the second guide rail 12. Two groups of adjusting screws 16 and nuts are arranged. A synchronous wheel 17 is arranged on the adjusting screw 16. A synchronous belt 18 is arranged on the two synchronous wheels 17. When one adjusting screw 16 rotates, the two adjusting screws 16 rotate synchronously, so that the second guide rail 12 can move laterally and stably on the third guide rail 13, and the distance between the cup stopper 15 and the top cup member 14 can be adjusted quickly and accurately.

[0027] The cup holder 25 includes a first cross bar 251 and a second cross bar 252, and there is a material support 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 the cup body is supported by the two cross bars. A spacer 26 is also provided between adjacent cup holders 25, and the spacer 26 is installed on the cup holder 25. The spacer not only acts as a material block, but also separates adjacent cup bodies, so that each group of cups has an independent space and is not interfered with by other groups. The spacer 26 is small at the top and large at the bottom, and the cavity between adjacent spacers 26 is an inverted trapezoid, so that the entrance of the cup holder 25 is relatively larger, which is conducive to the entry and discharge of disposable cups.

[0028] The cup-push component 4 is connected to the beginning of the conveying component 2. The cup-push component 4 includes a push plate 41 for pushing materials longitudinally. The push plate 41 pushes the fed materials to the cup-supporting component 25 of the conveying component 2, so as to realize the automatic pushing of the disposable cup 5. The cup-push component 4 also includes a support plate 44, which is not lower than the conveying component 2. The push plate 41 is arranged above the support plate 44. The support plate 44 supports the disposable cup 5, and the push plate 41 pushes the disposable cup 5 on the support plate 44 to leave the support plate 44 and enter the cup-supporting component 25 of the conveying component 2. There are a plurality of push plates 41, which are evenly installed on the annular transmission belt 43. The transmission belt 43 is intermittently transmitted longitudinally. The push plates 41 are arranged transversely, and there is a material cavity 42 between adjacent push plates 41. The transmission of the transmission belt 43 drives the push plates 41 to move, and the push plates 41 push the disposable cup to move longitudinally. The longitudinal pushing section of the transmission belt 43 is provided with at least two stations, namely, a feeding station and a discharging station. The feeding station is provided with a conveyor belt 45 for horizontal conveying, and the conveyor belt 45 is arranged below the push plate 41, and the conveyor belt 45 is connected with the support plate 44. As shown in the attached figure, the disposable cups are horizontally stacked and placed horizontally on the conveyor belt 45. When the disposable cups enter the feeding station horizontally, the transmission belt 43 stops conveying, and the material cavity 42 faces the conveyor belt 45 to receive the disposable cups 5. After the disposable cups enter the material cavity 42 of the feeding station, the transmission belt 43 is driven, and the push plate 41 pushes the disposable cups on the conveyor belt 45 forward to the support plate 44. Each time the transmission belt 43 is driven, a new group of disposable cups 5 is received, and the disposable cups 5 of the previous group are pushed forward by one position. The push plate 41 at the discharging station pushes the cups to leave the support plate 44 and enter the cup support member 25. It is better that the outer diameter of the material cavity 42 matches that of the cup body, so as to avoid shaking of the material during the forward movement and improve the accuracy and stability of the feeding.

[0029] The working principle of the preferred embodiment is further described below in conjunction with the accompanying drawings: the disposable cup 5 with the film set is sent to the conveyor belt 45. At this time, the disposable cup 5 is wrapped with a film and placed horizontally on the conveyor belt 45. The conveyor belt 45 transports it horizontally to the material chamber 42 of the feeding station. The transmission belt 43 is driven, and the push plate 41 pushes the disposable cup 5 at the feeding station to move forward until the disposable cup 5 enters the discharging station. The push plate 41 pushes it out, and the disposable cup 5 falls on the cup support member 25 at the feeding end and is placed between the cup blocking member 15 and the top cup member 14. With the transmission of the left transmission chain 21 and the right transmission chain 22, the discharging end of the cup support member 25 moves and passes through the heat shrinking furnace 3. The top cup member 14 enters the exit holding section. Entering the extending section, as the cup supporting member 25 moves forward, the top cup member 14 gradually moves toward the cup blocking member 15 along the first guide rail 11 in the extending section, and enters the cup body, pushing the film at the cup mouth into the cup, and the film fits with the inner wall of the cup body; then entering the extending and holding section, the top cup member 14 remains in the extended state, and the film shrinks under the heating of the heat shrinking furnace 3, wraps the cup body tightly and covers the inner wall of the cup body; then entering the exiting section, the top cup member 14 gradually moves away from the cup blocking member 15 along the first guide rail 11, and the distance between the two gradually increases. Finally, the top cup member 14 enters the exiting and holding section, maintains the distance from the cup blocking member 15, and the disposable cup that has completed heat shrinkage is sent to the discharge end, which is the end of the conveying component 2. At this time, the two ends of the disposable cup are not restricted, and the disposable cup is separated from the cup supporting member.
