Description

Technical Field

[0001] The utility model relates to a curling mechanism for paper cups and bowls, in particular to a bottom support device thereof. Background Art

[0002] Paper containers such as paper cups or paper bowls (collectively referred to as paper cups for ease of description) have a curled edge structure at their cup mouths, and generally go through processes such as oil dipping, pre-curling, and final curling for curling the mouth. The curling die of the curling mechanism (set as pre-curling or final curling according to requirements) has corresponding grooves (such as R grooves, etc.) to curl the cup mouth. The curling die cooperates with the lifting to curl the paper cup below. After curling is completed, the curling die rises and separates from the paper cup below, so that the paper cup on the turntable can rotate with the turntable to complete the forming of the paper cup in the subsequent process. However, the grooves of the curling die are prone to getting stuck with the cup mouth of the paper cup (especially for paper cups with large bottoms or large cup body angles) after curling, resulting in the problem that the curling die brings the paper cup up when it rises. The problem is more obvious when the cup size and angle are larger. After the paper cup is lifted, it will shift on the turntable, affecting subsequent operations. Summary of the Utility Model

[0003] In view of the technical problems existing in the background art, the technical problem to be solved by the utility model is to provide a bottom support device for preventing the paper cup from being carried away in a curling mechanism that avoids the displacement of the paper cup.

[0004] To solve the above technical problems, the utility model adopts the following technical solutions: The bottom support device for preventing the paper cup from being carried away in the curling mechanism includes a lifting base and a cup bottom tray, and also includes a cup bottom sucking mechanism for preventing the paper cup from being carried away. It is characterized in that: the cup bottom tray is connected to the upper end of the lifting base, a bottom padding boss is further provided on the upper side of the cup bottom tray, and a cup supporting part is provided around the bottom padding boss; the cup bottom sucking mechanism includes a cup bottom sucking air port, the cup bottom sucking air port is arranged in the bottom padding boss, the cup bottom sucking air port is connected to the lifting base, the cup bottom sucking air port is arranged upward, and the cup bottom sucking air port is further connected to an air suction channel.

[0005] The following various optimizations or supplementary explanations can be further carried out on the above technical solutions respectively.

[0006] For example, the upper end of the lifting base has a connecting flange, and the cup bottom tray is connected to the connecting flange.

The suction cup bottom air port is located at the mounting through hole, and the suction channel includes a suction cup rod, and the suction cup bottom air port is connected to the suction cup rod, and the suction cup rod is set through the mounting through hole.

[0010] Wherein, the upper end of the suction cup rod is provided with a suction cup bottom air port, and the suction cup bottom air port also includes a suction cup.

[0013] In addition, the upper side of the bottom boss has a bottom surface, the bottom surface of the bottom boss is provided with an air groove, the suction cup bottom air port is connected to the air groove, and the air groove is an annular groove.

[0014] For example, the air ports at the bottom of the suction cup are distributed along the air grooves, and a connecting transition air groove is provided between the bottom boss and the cup bottom tray. The connecting transition air groove adopts an annular air groove, and the air ports at the bottom of the suction cup are connected to the air suction channel through the connecting transition air groove.

[0015] The beneficial effect of the utility model is that the bottom support device of the rolling mechanism can not only support the bottom of the paper cup during the rolling process by the cup bottom tray to ensure smooth rolling and relatively good rolling effect, but also can prevent the paper cup from being lifted up and displaced after the rolling is completed by sucking the cup bottom through the suction cup bottom air port, so that the paper cup is in a relatively stable position and the displacement of the paper cup affects the subsequent processing and manufacturing.

Specific embodiments

[0025] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model; obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0026] Referring to the accompanying drawings, the bottom tray device for preventing the cup from being taken away in the curling mechanism in the embodiments of the present embodiment includes a lifting base 1 and a cup bottom tray 2. The cup bottom tray 2 is connected to the upper end of the lifting base 1. The cup bottom tray 2 can be lifted and lowered with the lifting base 1, and the cup bottom tray 2 can hold the paper cup 20 to cooperate with curling. Among them, a bottom padding boss 4 is further provided on the upper side of the cup bottom tray 2. The bottom padding boss 4 can extend into the bottom of the cup bottom of the paper cup 20. The cup bottom tray 2 is provided with a cup holding part 5 around the bottom padding boss 4, and the cup bottom tray 2 is held by the cup holding part 5 to hold the bottom of the paper cup. In addition, the bottom tray device for preventing the cup from being taken away in the curling mechanism further includes a cup bottom sucking mechanism 3 for preventing the cup from being taken away. The cup bottom sucking mechanism 3 can suck the cup bottom to prevent the paper cup from being taken away and displaced during curling.

[0027] Among them, the sucker cup bottom mechanism 3 includes a sucker cup bottom air port 6, which is arranged in the bottom pad boss 4. The sucker cup bottom air port 6 is connected to the lifting base 1 and will rise and fall together with the lifting base 1. The sucker cup bottom air port 6 is arranged upward, and the bottom pad boss 4 can extend into the bottom of the cup, so that the sucker cup bottom air port 6 can cooperate smoothly to suck the cup bottom. For example, when sucking the cup bottom plane, the sucker cup bottom air port 6 is also connected to an air suction channel 7, and the sucker cup bottom air port 6 is supplied with air for suction (such as a negative pressure air source) through the cooperation of the air suction channel 7.

[0028] During the curling process, the cup bottom tray 2 rises with the lifting base 1. The cup supporting part 5 on the cup bottom tray 2 can cooperate to support the cup bottom of the paper cup above to cooperate with the curling, and its cup bottom boss also extends into the bottom of the cup. The sucker cup bottom air port 6 will also rise together, and the sucker cup bottom air port 6 can suck the cup bottom. During the curling process, the cup bottom of the paper cup is supported smoothly for curling. After the curling is completed, the cup bottom of the paper cup is sucked by the sucker cup bottom air port 6 to prevent it from being lifted by the curling die (including the curling groove), and to prevent the curled paper cup from being taken away and displaced, ensuring that the paper cup is in a relatively stable position.

[0029] The bottom support device of the curling mechanism for preventing the cup bottom from being taken away can not only ensure the smooth progress of curling by the cooperation of the cup bottom tray 2 to support the bottom of the paper cup during the curling process, and the curling effect is relatively good, but also can suck the cup bottom by the cooperation of the sucker cup bottom air port 6 to prevent the paper cup after curling from being lifted and taken away and displaced, so that the paper cup is in a relatively stable position and prevent the displacement of the paper cup from affecting the subsequent processing and production. Moreover, the anti-taking effect is better by the way of sucking the cup, and the paper cup will not be damaged.

[0030] Based on the above embodiments respectively, the following optimizations or further explanations can be carried out.

[0031] For example, the upper end of the lifting base 1 has a connecting flange 8, and the cup bottom tray 2 is connected to the connecting flange 8, which is convenient for assembly. Bolt and other fittings can be used for connection for disassembly, maintenance and replacement to meet different sizes of paper cups.

[0032] Among them, the lifting base 1 is connected to the lifting rod.

[0033] Among them, the bottom pad boss 4 is integrally connected to the cup bottom tray 2 or the bottom pad boss 4 is separately connected to the cup bottom tray 2. Among them, the upper side of the bottom pad boss 4 has a bottom pad surface 9; the bottom pad surface 9 adopts a bottom pad plane, which is more fitting and closer to the cup bottom when extending into the cup bottom.

[0034] The air suction channel 7 is connected to an air suction source (such as a negative pressure air source). The bottom cushion boss 4 and the cup bottom tray 2 are provided with vertically aligned and penetrating mounting through holes 10. The air suction port 6 at the bottom of the suction cup is located at the mounting through hole 10. The air suction channel 7 includes a suction cup rod 11. The air suction port 6 at the bottom of the suction cup is connected to the suction cup rod 11, and the suction cup rod 11 can pass through the mounting through hole 10 for installation, facilitating the adjustment of the relative vertical position to ensure the smooth and stable operation of the suction cup.

[0035] For example, the upper port of the suction cup rod 11 is provided with the air suction port 6 at the bottom of the suction cup. The air suction port 6 at the bottom of the suction cup also includes a suction cup 12 (such as a suction skin), and the suction cup effect is relatively good.

[0036] For instance, the suction cup rod 11 is a hollow vertical rod of the suction cup. The suction cup rod 11 is connected and installed on the lifting adjustment frame 13. The suction cup rod 11 can be adjusted in the relative vertical position along with the lifting adjustment frame 13 to ensure the smooth and stable operation of the suction cup during debugging. The lifting adjustment frame 13 is installed on the lifting base 1. The lifting adjustment frame 13, the suction cup rod 11, the air suction port 6 at the bottom of the suction cup, etc. will be lifted and lowered together with the lifting base 1. The lifting adjustment frame 13 is located below the cup bottom tray 2. The lifting adjustment frame 13 can conveniently adjust the relative vertical positions of multiple suction cup rods 11 and air suction ports 6 at the bottom of the suction cup on the lifting base 1 to ensure the smooth and stable suction of the cup during debugging. It can change according to specifications. For example, the height of the boss corresponds to the depth of the cup bottom to change the position of the air suction port 6 at the bottom of the suction cup.

[0037] The lifting adjustment frame 13 is equipped with a locking ring 14. The locking ring 14 is installed and sleeved on the lifting base 1. A locking groove 21 is formed on the locking ring 14. The locking ring 14 is equipped with a locking member (such as a screw, etc.). The locking member is used to loosen and tighten the locking groove 21 (such as the size of the spacing of the locking groove 21). After the locking member loosens the locking groove 21, the locking ring 14 can move on the lifting base 1 to adjust the vertical position; after the locking member tightens the locking groove 21, the locking ring 14 will hold the lifting base 1 to fix the position.

[0038] In addition to using the suction cup rod 11, another method can also be adopted. For example, the connecting flange 8 is provided with a set of first connecting through holes 15 arranged circumferentially, and the cup bottom tray 2 is provided with a set of second connecting through holes 16 arranged circumferentially. The first connecting through holes 15 and the second connecting through holes 16 are connected by fasteners (such as screws, etc.), so that the cup bottom tray 2 is connected and installed on the lifting base 1 by the fasteners; at least one first connecting through hole 15 and one second connecting through hole 16 form an air suction channel 7. The lower end of the air suction channel 7 is connected with an air connector 17, and the air suction port 6 at the bottom of the suction cup is communicated with the air suction channel 7. The structure is relatively compact. The air suction channel 7 is formed by the cooperation of the first connecting through holes 15 and the second connecting through holes 16 for air ventilation, and the air connector 17 is used to connect the air suction source. In addition, the upper side of the bottom cushion boss 4 has a bottom cushion surface 9, and an air groove 18 is provided on the bottom cushion surface 9. The air suction port 6 at the bottom of the suction cup is connected and matched with the air groove 18 to form a larger air suction cup bottom area, and the air suction cup bottom effect is relatively better; the air groove 18 can adopt an annular groove (such as a circular ring). The air suction port 6 at the bottom of the suction cup is arranged along the air groove 18. An connecting and transitional air groove 19 can also be provided between the bottom cushion boss 4 and the cup bottom tray 2. The connecting and transitional air groove 19 adopts an annular air groove. The air suction port 6 at the bottom of the suction cup is connected with the air suction channel 7 through the connecting and transitional air groove 19. The connecting and transitional air groove 19 can connect all the air suction ports 6 at the bottom, and the air suction ports 6 at the bottom of the suction cup can be evenly distributed, and the suction force is relatively more uniform when sucking the cup bottom.
