[0002] Qingtuan is a traditional specialty snack in the Jiangnan region. It is made by mixing mugwort juice and glutinous rice flour to form a green skin, which is then wrapped with red bean paste or egg yolk and lotus paste.

The first clip 335 and the second clip are arranged in a staggered manner. The first clip 335 is provided with a first arc groove 3351 with an opening, and the second clip 336 is provided with a second arc groove 3361 with an opening. The opening of the first arc groove 3351 is arranged opposite to the opening of the second arc groove 3361. The first arc groove 3351 and the second arc groove 3361 are used to shrink the film from the outside to the inside along the radial direction of the envelope cavity 3131.

[0116] When the cutting mechanism 26 cuts the green ball, the film cutting device 50 cuts the film to cut out a sheet-shaped and independent film, and the film is held on the film packaging fixing plate 311 by the film pressing mechanism 32. After the cutting mechanism 26 completes the cutting of a green ball, the film pressing mechanism 32 releases the film. At this time, the green ball falls onto the film under the action of gravity, passes through the through hole 3111 and enters the film packaging cavity 3131. At this time, the film only wraps the lower part of the outer surface of the green ball.

[0117] When it is necessary to shrink the film from the outside to the inside along the radial direction of the coating cavity 3131, the control box 70 controls the solenoid valve seat 15 to conduct the pipeline used to drive the piston of the first cylinder 331 to extend and retract, and to conduct the pipeline used to drive the piston of the second cylinder 332 to extend and retract. At this time, the first guide rod 333 drives the first clamp 335 and the second guide rod 334 drives the second clamp 336 to move towards each other, so as to reduce the space between the first clamp 335 and the second clamp 336, so that the diaphragm wraps the unwrapped surface above the green ball. At the same time, the vacuum mechanism creates a negative pressure environment inside the flexible clamp 34, so that the clamp 341 shrinks from the outside to the inside along the radial direction of the coating cavity 3131, so as to improve the reliability of the diaphragm wrapping the green ball. At the same time, the control box 70 controls the rotary drive motor 314 to drive the coating seat 313 to rotate through the pulley mechanism, so as to rotate and close the diaphragm to complete the wrapping of the diaphragm by the green ball.

[0118] After completing the wrapping of the green rice dumpling, the control box 70 controls the solenoid valve seat 15 to conduct the pipeline for driving the piston rod of the first cylinder 331 to retract, and conducts the pipeline for driving the piston rod of the second cylinder 332 to retract. At this time, the first guide rod 333 drives the first clamp 335 and the second guide rod 334 drives the second clamp 336 to return to the initial position. At the same time, the vacuum generator 35 of the control box 70 stops working to disconnect the air path between the vacuum generator 35 and the flexible clamp 34, so that the clamp 341 of the flexible clamp 34 releases the green rice dumpling and returns to the initial position, thereby releasing the green rice dumpling that has been wrapped. Subsequently, the wrapping fixing plate 311 rotates to the second position to allow the wrapped green rice dumpling to fall onto the conveying mechanism 60.

The film pressing cylinder 321 is used to drive the pressing plate 323 to press the film on the film coating fixing plate 311.

[0121] When the film needs to be pressed onto the film fixing plate 311, the control box 70 controls the solenoid valve seat 15 to conduct the pipeline for driving the piston of the film pressing cylinder 321 to extend and retract, so that the film pressing cylinder 321 drives the pressing plate 323 to press the film onto the film fixing plate 311, so that the film cutting device 50 can complete the cutting of the film. After the film cutting device 50 completes the cutting of the film, the control box 70 controls the solenoid valve seat 15 to conduct the pipeline for driving the piston of the film pressing cylinder 321 to retract, so that the film can wrap the green dumpling.

[0132] The slide groove on the connecting seat 42, the adjustment seat 461 is slidably connected in the slide groove on the connecting seat 42, and the film pressing wheel 49 is rotatably connected to the adjustment seat 461. The guide sleeve 462 is connected to the film feeding fixed plate 41, the guide rod 463 is slidably connected in the guide sleeve 462, and one end of the guide rod 463 is connected to the adjustment seat 461. The adjustment plate 464 is connected to the end of the guide rod 463 away from the adjustment seat 461. The adjustment screw 465 is rotatably connected to the adjustment plate 464 and is threadedly connected to the film feeding fixed plate 41. The handle 466 is connected to the adjustment screw 465. The locking assembly is connected to the adjustment plate 464, and is used to lock the adjustment screw 465.

The adjusting screw 465 is rotatably connected in the locking sleeve 467. The second locking bolt penetrates the locking sleeve 467 and abuts against the adjusting screw 465 to lock the adjusting screw 465.

[0133] By rotating the handle 466, the handle 466 drives the adjusting screw 465 to rotate. Since the adjusting screw 465 is threadedly connected to the film feeding fixing plate 41, when the adjusting screw 465 rotates, it drives the film pressing wheel 49 to move relative to the film feeding wheel 45 along the radial direction of the film feeding wheel 45 through the adjusting seat 461 to adjust the gap between the film feeding wheel 45 and the film pressing wheel 49. After completing the adjustment of the film pressing wheel 49, the adjusting screw 465 is locked by tightening the second locking bolt to maintain the gap between the film feeding wheel 45 and the film pressing wheel 49.

[0134] In the present application, a film guide mechanism 48 is fixed on the frame 12, and the guide mechanism includes a first guide roller 481, a second guide roller 482 and a third guide roller 483.

[0135] After the film is guided out by the film feeding wheel 45, it enters the first guide roller 481, the fourth guide roller, the second guide roller 482 and the third guide roller in sequence, and then enters the film coating fixing plate 311 in the film coating device 30, and the film enters the bottom of the fourth guide roller from the top of the first guide roller 481, and enters the top of the second guide roller 482 from the bottom of the fourth guide roller.

[0136] It should be pointed out that when the Qingtuan film wrapping machine is working, the film needs to be returned to its original state. The control box 70 first controls the servo motor 39 to rotate to drive the drive shaft 38 to rotate, and the drive shaft 38 rotates through the rotating plate 37. When the rotating plate 37 rotates, it drives the film wrapping mechanism 31 to rotate. At this time, the clamping mechanism 33 presses the film on the film wrapping fixing plate 311 of the film wrapping mechanism 31. When the film wrapping fixing plate 311 rotates, it drives the film to be tightened. At this time, the fourth guide roller slides relative to the adjustment frame 484 under the action of the film tension and separates from the second induction switch. At this time, the second induction switch generates a separation electrical signal and transmits the separation electrical signal to the control box 70. After receiving the separation electrical signal, the control box 70 controls the film feeding motor 44 to start according to the separation electrical signal. After the film feeding motor 44 starts, it drives the film feeding wheel 45 to rotate so that the film passes through the film guide mechanism 48 and enters the film wrapping fixing plate 311.

[0139] When it is necessary to cut the film for any one of the film wrapping mechanisms 31, when the film wrapping mechanism 31 rotates to the first position, the control box 70 controls the solenoid valve seat 15 to open the air path for the piston rod of the film cutting cylinder 52 to extend, so as to control the extension of the piston rod of the film cutting cylinder 52, so that the film cutting knife 54 extends into the film cutting groove adjacent to the film wrapping mechanism 31 to cut the film. After completing the cutting of the film, the control box 70 controls the solenoid valve seat 15 to open the air path for the piston rod of the film cutting cylinder 52 to retract, so that the film cutting knife 54 returns to the initial position to facilitate the next film cutting.

[0140] In the present application, a temperature sensor (not shown in the figure) is installed on the film cutting knife 54, and the temperature sensor is electrically connected to the control box 70 for transmitting the temperature data of the film cutting knife 54 to the control box 70. When the temperature sensor detects that the electric heating element 55 heats the film cutting knife 54 to a preset temperature set in the control box 70, the control box 70 controls the electric heating element 55 to cut off the power to stop heating the film cutting knife 54; and when the temperature sensor detects that the temperature of the film cutting knife 54 is lower than the preset temperature set in the control box 70, the control box 70 controls the electric heating element 55 to be powered on to continue heating the film cutting knife 54.
