Technical Field

[0001] This utility model relates to the field of food packaging technology, and in particular to a bagged plum packaging device. Background Technology

[0002] A bagged plum packaging device is a specialized piece of equipment used to automatically dispense and seal granular or blocky materials such as plums. It typically integrates functions such as filling and sealing.

[0003] In traditional bagged plum packaging devices, the conventional single-layer flat-pressure heat-sealing structure lacks secondary sealing protection. This traditional single-layer flat-sealing design is severely unsuitable for the material characteristics of plums, which are high in sugar and viscosity and prone to oxidation and mold growth. During storage and handling, moisture can easily seep into the bag, and micro-leakage at the seal can allow air to enter, causing the plum sugar frosting to melt, the fruit to turn brown and moldy. This results in damage to the core quality of the product, failure to meet food hygiene standards, and a significant reduction in product shelf life. It also seriously affects production stability and food safety. Therefore, it is particularly important to design an integrated heat-shrink sealing bagged plum packaging device. Utility Model Content

[0004] To address the issues of insufficient protective capacity of packaging bags produced by traditional bagged plum packaging devices and the inability of conventional flat sealing structures to achieve preservation effects, this utility model proposes an integrated bagged plum packaging device with a heat-shrink module. Through the integrated heat-shrink module design in a sealed mode, it can achieve integrated operation of heat-sealing the plum bag and trimming the excess material, while also achieving uniform heat shrinking and shaping of the bag body and sealing and freshness locking effects, greatly improving the sealing reliability and food safety of the finished product.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a bagged plum packaging device, comprising a movable packaging component and a fixed packaging component, wherein the fixed packaging component is disposed on top of the movable packaging component;

Two electric cylinders 104 are bolted to one side of the outer wall of the limiting plate 103. Both electric cylinders 104 are used to push the movable plate 102 under the restriction of the limiting plate 103 to merge the movable packaging component 1 and the fixed packaging component 2. A gate 108 is fixedly connected to one side of the inner wall of the movable plate 102. A heat sealing machine 109 is provided on one side of the inner wall of the movable plate 102. The heat sealing machine 109 is located at the bottom of the gate 108 and is used to heat-seal the top of the packaging bag.

[0026] The overall effect achieved by this embodiment is as follows:

[0027] The above components form a complete bagged plum packaging device. The fixed packaging component 2 is responsible for positioning and receiving the packaging bag and fixing the molded and sealed cavity. The movable packaging component 1 is responsible for driving the bag's translation and mold closing, heat sealing, trimming excess material, and supplying hot air for heat shrinking. The two components work together to achieve integrated sealing packaging and heat shrinking of the plum bags. The workbench 101 serves as the overall support foundation of the device. A limit plate 103 is fixedly connected to its top, providing a stable mounting position for two electric cylinders 104. Two electric cylinders 104 are bolted to one side of the outer wall of the limit plate 103, providing continuous linear driving force for the translation, mold closing, and mold opening actions of the movable plate 102. The output ends of the two electric cylinders 104 are respectively connected to the movable plate. Two protrusions 105 on one side of the outer wall of workbench 102 are fixedly connected to achieve stable transmission of driving power. A movable plate 102 is slidably connected to the top of workbench 101, providing an integrated mounting carrier for heat shrinking, sealing, and cutting functional components. A hot air blower 106 is embedded in the inner surface of the movable plate 102 to provide uniform and controllable circulating hot air for heat shrinking operations. A motor 107 is provided on one side of the outer wall of the hot air blower 106 to provide stable power output for the hot air blower 106. A gate 108 is fixedly connected to one side of the inner wall of the movable plate 102 for cooperating with the knife holder 203 to cut and separate excess film material from the packaging bag. A heat sealing machine 109 is provided on one side of the inner wall of the movable plate 102 for heat-sealing the bag opening. A fixed... Packaging component 2, receiving box 201, is fixedly connected to the top of workbench 101 as the main support of the fixed packaging component 2. It is used to receive the heat shrink film packaging bag containing plums. A fixing plate 202 is fixedly connected to the top of the receiving box 201. It is used to form a sealed heat shrink working cavity isolated from the outside world by correspondingly fitting with the movable plate 102. A knife holder 203 is embedded in one side of the inner wall of the fixing plate 202. Two springs 204 are elastically connected to one side of the inner wall of the fixing plate 202 to provide an adaptive buffer elastic pre-tightening force for the pressing operation of the pressure plate 205. The outer surface of the two springs 204 is elastically connected to the pressure plate 205 on one side, which is used to pre-press and fix the bag mouth when the mold is closed. When carrying out the bagged plum packaging operation, the food-grade heat shrink film packaging bag containing plums is first placed in the mold. The shrink-wrapped packaging bag is smoothly placed into the receiving box 201, completing the pre-positioning of the packaging bag. Then, the equipment is started, and the output ends of the two electric cylinders 104 extend, pushing the movable plate 102 smoothly along the top of the worktable 101 towards the fixed plate 202 via the boss 105. During the mold closing process, the pressure plate 205 contacts the bag opening first, and the rebound force generated by the compression of the spring 204 flattens and tightens the bag opening. After the movable plate 102 and the fixed plate 202 are completely in contact, a sealed heat-shrinking working cavity is formed. Then, the heat sealing machine 109 is started to complete the heat-sealing of the pressed bag opening, realizing the basic sealing of the packaging bag. The gate 108 cuts into the knife holder 203 with the mold closing stroke, completing the flat cutting and separation of the excess film material at the bag opening. Afterwards, the motor 107 drives the hot air blower 106 to start.Circulating hot air at a preset temperature is output into the sealed cavity to evenly heat the sealed packaging bag, causing the heat-shrink film to adhere to the pile of plums and complete the heat-shrinking and shaping process. After the heat-shrinking process is completed, the packaged product can be directly removed from the receiving box 201, thus completing the packaging of a single bag of plums. Compared with traditional equipment, this device avoids the problems of insufficient protective capacity of packaging bags produced by traditional equipment and the inability of conventional flat sealing structures to achieve preservation effects. It effectively balances practicality and functionality in daily use, and can significantly improve the sealing reliability and food safety of the finished product.
