Description

Technical Field

[0001] This utility model belongs to the field of packaging machine technology, specifically relating to a liquid packaging machine with liquid clamping and sealing three-side sealing. Background Technology

[0002] As market demands for packaging bags continue to rise, the impact of gases inside packaging bags on product preservation is receiving increasing attention. In the field of liquid pouch packaging, traditional packaging methods easily lead to residual gases inside the bags. This not only increases transportation costs, but the oxygen in the gas can also cause the material to oxidize and deteriorate during storage and transportation, affecting product quality and shelf life. Therefore, developing a liquid packaging machine that can reduce residual gases inside packaging bags has become an urgent problem to be solved in this field. Utility Model Content

[0003] To address the problems mentioned in the background section, this invention provides a liquid packaging machine with a liquid-clamping and three-side sealing mechanism. The aim is to solve the problems of residual gas in the bags after packaging by existing liquid packaging machines, which leads to increased transportation costs and easy oxidation and deterioration of the material. The machine produces bags with virtually no gas, reducing transportation costs and effectively preventing material oxidation.

[0004] A liquid packaging machine with liquid clamping and three-side sealing includes a housing. The housing is equipped with a film roll holder, a forming device, a bag-pulling wheel, a longitudinal sealing device, an extrusion device, a transverse sealing device, and a conveyor belt. The film roll holder holds rolled packaging material, which enters the forming device and is bent and shaped therein. The shaped packaging material is then conveyed downwards by the bag-pulling wheel. The longitudinal sealing device, located above the bag-pulling wheel, seals the packaging material longitudinally. The extrusion device, positioned above the packaging machine, includes upper and lower material level sensors, is driven by a cylinder, and has a rubber roller driven synchronously by a servo motor to fill the packaging material. The transverse sealing device has a cutter; when the filled packaging material moves to the transverse sealing device, the device seals the material, and the cutter extends to cut the packaging material. The conveyor belt, located below the transverse sealing device, transports the cut packaging bags.

[0005] As a preferred technical solution of this utility model, the material level sensing component of the extrusion device is used to keep the material level between the two material level sensing components so as to ensure that the material is always above the liquid level for packaging.

[0006] As a preferred technical solution of this utility model, during the process of extruding the material, the bag-pulling wheel and the rubber roller rotate synchronously to ensure that the packaging material continues to move downward.

[0007] As a preferred technical solution of this utility model, the cutter of the horizontal sealing device is located in the middle of the horizontal sealing device and extends synchronously to cut the packaging material when the horizontal sealing device performs the sealing operation.

[0008] As a preferred technical solution of this utility model, the roll film support is rotatably mounted on the box body to facilitate the release and transport of the roll packaging material.

[0009] As a preferred technical solution of this utility model, the longitudinal sealing device uses heat sealing technology to longitudinally seal the packaging material to ensure the sealing performance.

[0010] As a preferred technical solution of this utility model, the conveyor belt speed is matched with the downward speed of the packaging material to ensure that the cut packaging bag can be smoothly transported to the designated position.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] Reduced transportation costs: Since the packaged bags contain almost no gas, compared to traditional packaging methods, the increased transportation volume caused by gas occupying space is reduced, thereby lowering transportation costs.

[0013] Preventing material oxidation and deterioration: By packaging the material with it always above the liquid level, oxygen is isolated from the material, effectively preventing oxidation and deterioration during storage and transportation, extending the shelf life of the material, and ensuring product quality.

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model. Example

[0019] like Figure 1 As shown;

[0020] A liquid packaging machine with liquid clamping and sealing three-side sealing.

[0021] In this implementation plan: To solve the technical problems existing in the prior art, such as the "traditional packaging methods easily leave residual gas in the packaging bag, which not only increases transportation costs, but also causes the oxygen in the gas in the bag to be oxidized and deteriorated during storage and transportation, affecting product quality and shelf life" in practical use, this problem is obviously a real and difficult problem to solve. Therefore, in order to solve this technical problem, a liquid-clamping and sealing three-side sealing liquid packaging machine is provided on this basis.

[0022] like Figure 1 As shown in the figure;

[0023] Based on the above,

[0024] The machine includes a housing 2, on which are mounted a film support 1, a forming device 3, a bag-pulling wheel 4, a longitudinal sealing device, an extrusion device 5, a transverse sealing device 6, and a conveyor belt 7. The film support 1 holds rolled packaging material, which enters the forming device 3 from the film support 1 and is bent and shaped therein. The shaped packaging material is then passed downwards by the bag-pulling wheel 4. The longitudinal sealing device is located above the bag-pulling wheel 4 and is used to seal the packaging material longitudinally. The extrusion device 5 is located above the packaging machine and has two material level sensing components, driven by a cylinder, and equipped with a rubber roller that rotates synchronously driven by a servo motor, used to fill the packaging material with material. The transverse sealing device 6 is equipped with a cutter. When the filled packaging material moves to the transverse sealing device 6, the transverse sealing device 6 performs a sealing operation and the cutter extends to cut the packaging material. The conveyor belt 7 is located below the transverse sealing device 6 and is used to transport the cut packaging bag.

[0025] The material level sensing component of the extrusion device 5 is used to keep the material level between the two material level sensing components, so as to ensure that the material is always above the liquid level for packaging.

[0026] During the material compression process, the bag-pulling wheel 4 and the rubber roller rotate synchronously to ensure that the packaging material continues to move downward.

[0027] The cutter of the horizontal sealing device 6 is located in the middle of the horizontal sealing device 6 and extends to cut the packaging material simultaneously when the horizontal sealing device 6 performs the sealing operation.

[0028] The roll film holder 1 is rotatably mounted on the box 2 to facilitate the release and transport of roll packaging materials.

[0029] The longitudinal sealing device uses heat sealing technology to seal the packaging material longitudinally, ensuring the seal is airtight.

[0030] The conveyor belt 7 is matched with the downward speed of the packaging material to ensure that the cut packaging bag can be smoothly transported to the designated position.

[0031] Equipment Installation and Commissioning: First, install all components of the packaging machine onto the housing according to the design requirements, ensuring the accurate positioning of components such as the film roll holder, forming device, bag pulling rollers, longitudinal sealing device, extrusion device, transverse sealing device, and conveyor belt. After installation, commission the equipment, check the smooth operation of each component, and adjust the position of the material level sensor to accurately control the material level.

[0032] Packaging Operation: Install the roll of packaging material onto the film roll holder and start the equipment. After the packaging material is bent and shaped in the forming unit, it is longitudinally sealed by the longitudinal sealing device and then conveyed downwards. When the bag-pulling roller pulls the packaging material to the set length, the cylinder of the extrusion device drives the rubber roller to press it, and the servo motor drives the rubber roller to rotate, filling the packaging material with material. During the filling process, the bag-pulling roller and the rubber roller rotate synchronously to ensure the continuous downward movement of the packaging material. When the formed packaging bag without material reaches the horizontal sealing device, the horizontal sealing device performs sealing and cutting operations. The cut bag is conveyed by the conveyor belt to the designated location for collection.

[0033] Finally, it should be noted that the above are merely preferred embodiments of this utility model and are not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
