Description

Technical Field

[0001] This utility model relates to the field of rolling vacuum packaging machine technology, specifically a sealing and shaping device for a rolling vacuum packaging machine. Background Technology

[0002] Rolling vacuum packaging machines, also known as continuous vacuum packaging machines or fully automatic chain vacuum packaging machines, are a type of high-efficiency food packaging equipment. Their working principle primarily involves chain drive to achieve automatic cap tilting and continuous product output.

[0003] When using existing rolling vacuum packaging machines, the packaging bag is usually placed on the placement strip first, and then the pressure strip is flipped to turn it to the bag opening. However, when the pressure strip is flipped for a long time, the friction time on the inside of the pressure strip is too long, which will cause the pressure strip to become less smooth when flipping. In addition, the current pressure strip is placed directly at the bag opening. When there are too many objects in the packaging bag or the packaged items are bulging, the bag opening may be stretched open, so that the pressure strip cannot press the bag opening tightly. Utility Model Content

[0004] The purpose of this invention is to provide a sealing and shaping device for a rolling vacuum packaging machine to solve the problems mentioned in the background art.

[0023] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.

[0024] Please refer to Figures 1-4 This utility model discloses a sealing and shaping device for a rolling vacuum packaging machine, comprising a packaging machine body 1, which is the main body of the rolling vacuum packaging machine. The packaging machine body 1 includes a conveyor belt 11 and a vacuum packaging device 12. The conveyor belt 11 is a structure for placing packaging bags and conveying them to the bottom of the vacuum packaging device 12, where they are vacuum packaged. The conveyor belt 11 is provided with a placement strip 13, and a pressure strip 14 is provided above the placement strip 13. The packaging bags are placed on the placement strip 13, and the pressure strip 14 provides initial pressure and shaping for the bag opening. The placement strip 13 is provided with a scale line 32. When placing packaging bags, the distance between every two packaging bags is observed through the scale line 32, so that the placement is more aesthetically pleasing and flat.

[0025] Movable components are provided on both sides of the bottom of the pressure strip 14. The movable components are used to drive the pressure strip 14 to move. The movable components include movable bolts 22. Movable openings 21 are provided on both sides of the placement strip 13. The movable bolts 22 are movably installed in the movable openings 21. Shaft grooves 23 are provided on the outer side of the movable bolts 22 and the inner side of the movable openings 21. Ball bearings 24 are provided inside the shaft grooves 23. The ball bearings 24 roll on the shaft grooves 23. The movable bolts 22 and the movable openings 21 do not contact each other. That is, the movable bolts 22 are supported by the ball bearings 24. When the pressure strip 14 is flipped, the ball bearings 24 roll on the shaft grooves 23, thereby reducing the friction between the movable bolts 22 and the movable openings 21, thus ensuring the smooth rotation of the pressure strip 14.

[0026] Mounting platforms 2 are provided on both sides of the outer side of the placement strip 13. The mounting platforms 2 are mounting structures. Multiple counterweights 4 are provided behind the pressure strip 14. Magnetic blocks 44 are provided on the outer sides of the counterweights 4 on both sides. A clamping connection assembly is provided above the mounting platform 2. The clamping connection assembly is used to connect the magnetic blocks 44. The clamping connection assembly includes an iron block 33. The magnetic blocks 44 are magnetically connected to the iron block 33. A ball groove 3 is provided on the mounting platform 2. A movable ball 31 is provided at the bottom of the iron block 33. The movable ball 31 is movably connected to the ball groove 3, that is, the movable ball 31 is stuck in the ball groove 3 and moves, so that the iron block 33 can move, thereby ensuring that the plane of the iron block 33 is connected to the magnetic block 44. Movable grooves 41 are provided on the inner side of the counterweights 4 on both sides. A spring 42 is provided behind the magnetic block 44. The spring 42 connects to Inside the rear side of the movable groove 41, when the magnetic block 44 is connected to the iron block 33, the spring 42 allows the magnetic block 44 to extend and retract to a certain extent. This allows it to connect to the iron block 33 when sealing packaging bags of different thicknesses. The weight of the counterweight 4 ensures that the sealing strip 14 is stably pressed at the bag opening. After packaging, the conveyor belt 11 moves the placement strip 13 downwards. The weight of the multiple counterweights 4 causes the magnetic block 44 to disengage from the iron block 33, opening the sealing strip 14 and causing the packaging bag to fall. The movable groove 41 is equipped with a limit rail 43, and the spring 42 is equipped with a limit block 45. The limit block 45 is slidably connected to the limit rail 43, meaning that the limit rail 43 limits the limit block 45, thus keeping the magnetic block 44 stable during extension and retraction.

[0027] The working principle of this utility model is as follows: During use, the packaging bag is placed on the placement strip 13, and the bag opening is initially pressed and shaped by the pressure strip 14. When the pressure strip 14 flips, the ball bearings 24 roll on the shaft groove 23, thereby reducing the friction between the movable bolt 22 and the movable opening 21, ensuring smooth flipping of the pressure strip 14. During flipping, the magnetic block 44 and the iron block 33 are interconnected, and the movable ball 31 moves in the ball groove 3, allowing the iron block 33 to move. This ensures that the plane of the iron block 33 is connected to the magnetic block 44, and the magnetic block 44 connects the iron block 33. At time 3, the magnetic block 44 can extend and retract to a certain extent through the spring 42, and the limiting block 45 is limited by the limiting rail 43, so that the magnetic block 44 remains stable when extending and retracting. Thus, when sealing packaging bags of different thicknesses, the iron block 33 can be connected, and the weight of the counterweight 4 makes the sealing strip 14 stably press at the bag opening. After packaging is completed, the placement strip 13 is moved downward by the conveyor belt 11, and the weight of multiple counterweights 4 makes the magnetic block 44 disengage from the iron block 33, the sealing strip 14 opens, and the packaging bag falls.
