Description

Technical Field

[0001] The utility model belongs to the field of paper cup processing equipment, and more specifically, relates to a heat dissipation mechanism for a paper cup forming machine. Background Art

[0002] When processing and forming paper cups, due to the high-power operation of the forming turntable of the forming machine, a large amount of heat will be generated. At the same time, when bonding the cup body and the cup bottom of the paper cup, heat treatment is also required. If the generated heat cannot be removed in time, it will cause damage to the performance of the machine due to insufficient heat dissipation, reduce the service life of the machine, increase the machine maintenance cost, and also pose a threat to the personal safety of the staff at any time in the case of insufficient heat dissipation.

[0003] A Chinese patent with the authorization announcement number CN206589389U discloses a heat dissipation device for a paper cup forming machine, including: a frame and a base. The base is surrounded by the frame. An upper die and a lower die are provided on the frame. A heat dissipation device is provided at the center of the lower die. The heat dissipation device includes a chassis, a fan provided at the center of the chassis, and a partition provided around the fan. A heat dissipation channel is formed between the partitions. The heat dissipation device of the paper cup forming machine of the utility model is provided with a heat dissipation device, which includes a chassis, a fan provided at the center of the chassis, and a partition provided around the fan. A heat dissipation channel is formed between the partitions. When the fan blades rotate, the air around the fan will be driven to flow. The flowing air will quickly flow along the heat dissipation channel to the periphery of the lower die, taking away the heat around the lower die.

[0004] The above technical solution has the following defects:

[0005] When using the above technical solution for paper cup forming, since heat dissipation is carried out by blowing air upwards, and the paper cup is not clamped and fixed when it falls into the lower die groove. When there is wind transmission, the paper cup will shake or fall off in the lower die groove, resulting in the failure of downward pressing and forming. Summary of the Utility Model

[0006] In view of the above defects, the utility model provides a heat dissipation mechanism for a paper cup forming machine, including a clamping mechanism for clamping and transporting the raw material of a bottomless paper cup, a downward pressing and forming mechanism for sealing the bottom of the paper cup raw material, a conveying pipe for conveying the formed paper cup, and a forming turntable. A central groove is opened in the middle of the forming turntable. A connecting flange is connected to the top of the forming turntable by bolts. Annularly arrayed flange heat dissipation holes are opened at the connecting flange. A bearing is installed on the bottom surface of the forming turntable. A rotating ring is fixed to the inner ring of the bearing. A plurality of screw holes are opened at the rotating ring. The top end of the air collecting hopper is threadedly fixed to each screw hole by bolts. The bottom of the air collecting hopper is communicated with an air inlet hose;

[0007] The inner walls of a number of lower die slots opened at the forming turntable are each provided with a number of heat dissipation holes. A number of heat dissipation pipes sleeved outside each lower die slot are inlaid on the inner wall of the forming turntable. The bottom end of the heat dissipation pipe is communicated with a diversion pipe. The top end of the heat dissipation pipe is communicated with the heat dissipation hole. The inner wall of the air collecting hopper is connected by an extension rod with an air outlet valve adapted to the diversion pipe.

[0008] Further, an outer ring is sleeved outside the forming turntable. A spiral groove is opened on the outer ring of the outer ring. A heat dissipation water pipe for water cooling and heat dissipation is arranged inside the spiral groove. Water valves for transmitting a cooling medium are installed at both the top end and the bottom end of the heat dissipation water pipe.

[0009] Further, the spiral groove is at least three turns.

[0010] Further, the air outlet valve is inlaid on the inner wall of the central groove and is in the same horizontal position as the diversion pipe. Magnetic attraction rings with opposite magnetic poles are respectively arranged at one ends of the air outlet valve and the diversion pipe close to each other.

[0011] Further, the heat dissipation pipe is in a spring shape.

[0012] The utility model has the following beneficial effects compared with the prior art:

[0013] Heat dissipation treatment can be realized without affecting normal forming operation;

[0014] The outer part of the forming turntable is cooled by water cooling in a circumferential surrounding cooling manner;

[0015] Inside the forming turntable, wind is conveyed to cool the lower die slots moved to the bottom of the clamping mechanism. In this way, it can be ensured that the paper cup raw materials already inside the lower die slots will not be blown by the wind. When the lower die slots are ready to be refilled after being conveyed by the conveying pipe, heat dissipation by wind will be carried out at this time. BRIEF DESCRIPTION OF THE DRAWINGS

[0023] Embodiment

[0024] As Figures 1-4 shown, this embodiment provides a heat dissipation mechanism for a paper cup forming machine, including a clamping mechanism 3 for clamping and transporting the raw materials of bottomless paper cups, a downward pressing and forming mechanism 2 for sealing the bottom of the paper cup raw materials, a transfer pipe 4 for conveying the formed paper cups, and a forming turntable 1. A central groove 7 is opened in the middle of the forming turntable 1. A connecting flange is connected to the top of the forming turntable 1 by bolts, and flange heat dissipation holes 6 are arranged in an annular array at the connecting flange. A bearing 12 is installed on the bottom surface of the forming turntable 1. The inner ring of the bearing 12 is fixed with a rotating ring 13. A number of screw holes are opened at the rotating ring 13. The top end of the air collecting hopper 17 is threadedly fixed to each screw hole by bolts. The bottom of the air collecting hopper 17 is communicated with an air inlet hose 18, so as to realize that after the air collecting hopper 17 is installed, the air collecting hopper 17 will not affect the normal rotation operation of the forming turntable 1;

[0025] A plurality of heat dissipation holes 11 are formed in the inner walls of the several lower die slots 5 opened at the forming turntable 1. A plurality of spring-shaped heat dissipation pipes 16 sleeved outside each lower die slot 5 are inlaid in the inner wall of the forming turntable 1. The bottom end of the heat dissipation pipe 16 is communicated with a diversion pipe 15, and the top end of the heat dissipation pipe 16 is communicated with the heat dissipation hole 11 (the outermost circle of the heat dissipation pipe 16 can be surrounded to the outside of the lower die slot 5 and is at the same horizontal position as the heat dissipation hole 11). The inner wall of the air collecting hopper 17 is connected with an air outlet valve 14 adapted to the diversion pipe 15 through an extension rod. The air outlet valve 14 is inlaid in the inner wall of the central groove 7 and is at the same horizontal position as the diversion pipe 15. Magnetic attraction rings with opposite magnetic poles are respectively arranged at one ends of the air outlet valve 14 and the diversion pipe 15 close to each other. The purpose is to facilitate the transmission of wind force after the magnetic attraction of the air outlet valve 14 and the diversion pipe 15 through the magnetic attraction rings. It should be noted that the orientation of the air outlet valve 14 needs to be limited to face the side of the clamping mechanism 3, that is, the shortest connection line with the clamping mechanism 3, so as to ensure that when the lower die slot 5 moves to the bottom of the clamping mechanism 3, the air outlet valve 14 and the diversion pipe 15 will be communicated, thereby completing the internal air-cooled heat dissipation treatment;

[0026] An outer ring 8 is also sleeved on the outer ring of the forming turntable 1. A spiral groove is formed in the outer ring of the outer ring 8, and the spiral groove has at least three turns. A heat dissipation water pipe 9 for water-cooled heat dissipation is arranged inside the spiral groove, and water valves 10 for transmitting a cooling medium are installed at the top end and the bottom end of the heat dissipation water pipe 9 respectively. It should be noted that a traditional water-cooled circulation device (such as a traditional water-cooled radiator composed of a water pump, a water pipe, a radiator and a water source) can be used for the cooling medium (such as coolant or distilled water), so as to complete the exchange of the cooling medium inside the heat dissipation water pipe 9.

[0027] It should be noted that the structure described in the present invention can be implemented in many different forms and is not limited to the embodiments. Any equivalent transformation made by those of ordinary skill in the art using the description and drawings of the present invention, or directly or indirectly applied in other related technical fields, such as the loading and unloading of other articles, is included in the protection scope of the present invention.
