Technical Field

[0001] The utility model relates to the technical field of food processing, in particular to a packaging machine for freeze-dried fruit production. Background Art

[0002] Freeze-dried fruit uses the vacuum freeze-drying method of a freeze dryer to freeze the moisture in the fruit in advance, and then sublimates the frozen moisture in the fruit in a vacuum environment to obtain freeze-dried fruit food.

[0003] Freeze-dried fruits need to be packaged during the processing. During the packaging, a packaging machine will be used to heat-seal the bag opening. When heat-sealing the bag opening, the bag containing the freeze-dried fruits is sent into the packaging machine for heat-sealing through a conveying device, while the bag opening of the bag is in an open state. The opening of the bag is opened at a large distance, thereby reducing the heat-sealing effect of the bag opening. Utility Model Content

[0004] The utility model aims to solve the problem that the bag opening of the packaging bag is in an open state in the prior art, the spacing between the bag openings of the packaging bag is large, thereby reducing the heat sealing effect of the bag openings of the packaging bag, and proposes a packaging machine for freeze-dried fruit production.

[0005] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0006] Design a packaging machine for freeze-dried fruit production, including a mounting plate, wherein:

[0007] A heat sealing mechanism is fixedly connected to the mounting plate, and a limiting mechanism for limiting the opening of the packaging bag is connected to the mounting plate;

[0008] The limiting mechanism comprises a first connecting rod, one end of which is fixedly connected to the mounting plate, the other end of which is fixedly connected to a groove frame, and one side of the groove frame is fixedly connected to the limiting frame.

[0009] Preferably, the heat sealing mechanism includes a motor, the motor is fixedly connected to the mounting plate, the output end of the motor is fixedly connected to a first turntable, a heating ring is sleeved on the first turntable, the bottom end of the mounting plate is rotatably connected to a rotating shaft, one end of the rotating shaft is fixedly connected to a second turntable, the second turntable is in contact with the heating ring, and the rotating shaft is connected to the output end of the motor through a belt transmission member.

[0010] Preferably, the first turntable is a heat-insulating turntable.

[0011] Preferably, the spacing between the bottom openings of the limiting frame gradually decreases along the length direction.

[0012] Preferably, a heat dissipation mechanism is fixedly connected to the mounting plate, and the heat dissipation mechanism includes a second connecting rod, one end of the second connecting rod is fixedly connected to the mounting plate, and the other end of the second connecting rod is fixedly connected to a fixing frame, and a plurality of through holes are provided at equal intervals along the length direction at the upper end of the fixing frame, and a fan is connected to each of the through holes.

[0013] Preferably, the second connecting rod and the fixing frame are an integral structure.

[0014] The utility model provides a packaging machine for freeze-dried fruit production, which has the following beneficial effects:

[0015] During the movement of the packaging bag containing the freeze-dried fruit, the bottom end of the limiting frame squeezes and closes the bag opening of the packaging bag containing the freeze-dried fruit, thereby reducing the opening distance of the bag opening of the packaging bag containing the freeze-dried fruit. After being limited by the limiting frame, the bag opening of the packaging bag enters the groove frame, and the groove frame continues to limit the bag opening of the packaging bag. After the bag opening of the packaging bag is shrunk, the opening distance is small, thereby improving the heat sealing effect of the bag opening of the packaging bag.

DETAILED DESCRIPTION

[0020] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0021] Example 1

[0022] Reference Figure 1-2 , a packaging machine for freeze-dried fruit production, comprising a mounting plate 1, wherein:

[0023] A heat sealing mechanism 2 is fixedly connected to the mounting plate 1, and a limiting mechanism 3 for limiting the bag opening of the packaging bag is connected to the mounting plate 1;

[0024] The limiting mechanism 3 includes a first connecting rod 31, one end of which is fixedly connected to the mounting plate 1, and the other end of the first connecting rod 31 is fixedly connected to a groove frame 32, one side of the groove frame 32 is fixedly connected to a limiting frame 33, and the bottom end opening spacing of the limiting frame 33 gradually decreases along the length direction.

[0025] Working process: when the packaging bag is heat-sealed and packaged, the conveying device conveys the packaging bag containing the freeze-dried fruit, and the upper end of the bag opening of the conveyed packaging bag containing the freeze-dried fruit enters the limiting frame 33. Since the bottom open spacing of the limiting frame 33 gradually decreases along the length direction, during the movement of the packaging bag containing the freeze-dried fruit, the side wall of the bag opening of the packaging bag containing the freeze-dried fruit gradually contacts the bottom end of the limiting frame 33, and the bottom end of the limiting frame 33 squeezes and closes the bag opening of the packaging bag containing the freeze-dried fruit, reducing the opening distance of the bag opening of the packaging bag containing the freeze-dried fruit. After being limited by the limiting frame 33, the bag opening of the packaging bag enters the groove frame 32, and the groove frame 32 continues to limit the bag opening of the packaging bag. Since the groove frame 32 has a certain length, after the bottom end of the groove frame 32 squeezes the side wall of the bag opening of the packaging bag, the bag opening of the packaging bag is shrunk and the opening spacing is small. After the shrunk bag opening enters the heat sealing mechanism 2 for heat sealing, the heat sealing effect of the bag opening of the packaging bag is improved.

At the same time, the output end of the motor 21 drives the rotating shaft 24 to rotate through the belt transmission member 26, and the rotating shaft 24 drives the second turntable 25 to rotate. The second turntable 25 and the heating ring 23 rotate synchronously, and the rotation direction is the same. After the bag opening of the packaging bag is located between the second turntable 25 and the heating ring 23, the heating ring 23 contacts the bag opening of the packaging bag and then performs heat sealing under the support limit of the second turntable 25.
