Description
Technical Field
[0001] This utility model relates to a vacuum packaging material shaping machine, specifically to a vacuum packaging material shaping component of the vacuum packaging material shaping machine. Background Technology
[0002] After vacuum packaging materials using a pre-packaging bag machine, if the materials are loose and in small pieces, they tend to accumulate at the bottom of the vacuum-packed bag, causing bulges that are both unsightly and detrimental to subsequent boxing and packaging. While some technologies, such as horizontal pre-packaging bag machines, are currently available, their effectiveness is not ideal. Therefore, there is an urgent need for a vacuum packaging material shaping machine specifically designed to reshape already vacuum-packed materials. The key is to develop a completely new vacuum packaging material shaping component. Summary of the Invention
[0003] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a compact vacuum packaging material shaping component specifically for shaping vacuum packaging materials.
[0004] This utility model is implemented through the following technical solution:
[0005] A vacuum packaging material shaping component includes a worktable and a turntable located above the worktable. The turntable is driven by a main motor to rotate in increments during operation. The turntable is characterized by having, in sequence along its circumference, a bag loading station, a vacuuming station, a vibration flattening station, a venting station, and a bag unloading station. Each station is equipped with a horizontal vacuum chamber assembly. Each vacuum chamber assembly has a chamber cover that can be opened upwards. An internal conveyor belt is horizontally laid inside the vacuum chamber of each vacuum chamber assembly. The internal conveyor belt is mounted on a vibration support. A pressing plate is located above the internal conveyor belt. The pressing plate is connected to a flattening cylinder, which is fixedly installed on the chamber cover.
[0006] The turntable has an even number of stations along the circumference, and the vacuum chamber components of adjacent stations are staggered in height.
[0007] The cavity cover is flip-connected to the turntable and pushed by a push rod. The upper end of the push rod is connected to the cavity cover, and the lower end is connected to the swing arm. The swing arm is oscillating and connected to the turntable. A roller is installed in the middle of the swing arm. The roller rolls on the working surface of the end face cam. The end face cam is fixedly installed on the worktable below the turntable.
[0008] With the above technical solution, when the vacuum-packed material is sent to the horizontally laid conveyor belt inside the vacuum chamber assembly at the bag-loading station, the packaging bag lies horizontally. Then, as the turntable rotates, the chamber cover is closed. At the vacuum-evacuation station, the vacuum chamber is evacuated, balancing the pressure inside and outside the vacuum-packed material. The material inside the bag then returns to a free state. Next, at the vibration and flattening station, the conveyor belt inside the chamber vibrates at high frequency, while the pressing plate presses against the material under the constant pressure of the flattening cylinder. Since the packaging bag is horizontal at this time, under the action of high-frequency vibration, the material that was originally piled at the bottom of the packaging bag begins to move towards the bag opening. Under the continuous downward pressing action of the pressing plate, the material inside the bag is finally laid flat in the packaging bag into a flat shape of approximately equal thickness. Then, at the degassing station, the vacuum chamber is degassed to restore normal pressure, and the material packaging is restored to vacuum packaging. Finally, at the bag-out station, the flattened and shaped vacuum-packed material is sent out of the vacuum chamber, thus realizing the automatic shaping of the vacuum-packed material. In addition, the vacuum chamber components of adjacent workstations are staggered in height, making the structure of the entire equipment more compact. Attached Figure Description
[0009] The present invention includes the following figures:
[0010] Figure 1 This is a schematic diagram of the structure of this utility model.
[0011] Figure 2 This is a schematic diagram of the vacuum chamber assembly.
[0012] Figure 3 This is a schematic diagram of the internal structure of the vacuum chamber assembly. Detailed Implementation
[0013] As shown in the figure, the vacuum packaging material shaping component of this utility model includes a workbench 1 and a turntable 2 located above the workbench 1. When the turntable 2 is working, it is driven by the main motor to rotate in an indexing manner. The turntable 2 has eight stations arranged in sequence along the circumference: one bag loading station, two vacuuming stations (one pre-vacuuming station with one vacuum pump in operation, and the other full vacuuming station with two vacuum pumps in operation), three vibration flattening stations (flattening and vacuuming at the same time), one venting station, and one bag unloading station. Each station is equipped with a horizontal vacuum chamber assembly. The vacuum chamber assemblies of adjacent stations are staggered in height. The turntable 2 is divided into upper and lower layers, which are used for the installation of the staggered vacuum chamber assemblies. Each vacuum chamber assembly has an upwardly movable chamber cover 3. The chamber cover 3 is flip-connected to the turntable 2 and pushed by a push rod 4. The upper end of the push rod 4 is connected to the chamber cover 3, and the lower end is connected to a swing arm 5. The swing arm 5 is oscillatingly connected to the turntable 2. A roller 6 is installed in the middle of the swing arm 5. The roller 6 rolls on the working surface of the end face cam 7. The end face cam 7 is fixedly installed on the worktable 1 below the turntable. The vacuum chamber of the vacuum chamber assembly is formed by the chamber cover 3 sealing the surface of the turntable 2. An internal conveyor belt 9 is horizontally laid inside the vacuum chamber of each vacuum chamber assembly. The internal conveyor belt 9 is installed on a vibration bracket 10. The vibration bracket 10 is driven by a vibration cylinder 11 to vibrate. The vibration cylinder 11 is installed on the turntable 2. A pressure plate 12 is provided above the internal conveyor belt 9. The pressure plate 12 is connected to a flattening cylinder 8, which is fixedly installed on the chamber cover 3.
[0014] The vacuum packaging material shaping component of the above technical solution works as follows: When the vacuum packaging material is fed to the horizontally laid conveyor belt inside the vacuum chamber assembly at the bag-loading station (at this time, the chamber cover of the vacuum chamber assembly is fully open), the packaging bag lies horizontally. Then, as the turntable rotates, the chamber cover closes. At the pre-vacuum station, one vacuum pump starts working, and the vacuum inside the vacuum chamber can reach 80% of the rated value. Next, at the fully vacuum station, two vacuum pumps start working, and the vacuum inside the vacuum chamber reaches the rated value, balancing the pressure inside and outside the vacuum packaging material. Thus, the material inside the bag returns to a free state. Then, at the vibration flattening station, the vacuum chamber is maintained under vacuum, and the conveyor belt inside the chamber is moved while the vibration motor is running. The belt vibrates at high frequency, while the pressing plate presses against the material under the constant pressure of the flattening cylinder. Since the packaging bag is horizontal at this time, the material that was originally piled up at the bottom of the packaging bag begins to move towards the bag opening under the action of high frequency vibration. Under the continuous pressing action of the pressing plate, the material inside the bag is finally spread out into a flat shape of basically equal thickness inside the packaging bag. Then, at the degassing station, the vacuum chamber is degassed and restored to normal pressure, and the material packaging is also restored to vacuum packaging. Finally, at the bag exit station, the chamber cover is opened again, and the external drive wheel drives the internal conveyor belt to perform a conveying action by contacting the external conveyor roller 13 of the internal conveyor belt. Thus, the vacuum-packaged material that has been flattened and shaped on the internal conveyor belt is sent out of the vacuum chamber.
