Description

Technical Field

[0001] This utility model relates to the field of packaging machine technology, specifically to a multi-functional pneumatic packaging machine for sealing. Background Technology

[0002] A pneumatic packaging machine is an automated packaging device that uses compressed air as a power source. It completes packaging operations by driving a mechanical structure through pneumatic components. Its core working principle is that compressed air, regulated by a control system, drives cylinders to perform clamping, sealing, cutting, and palletizing actions. The mechanical structure of a pneumatic packaging machine includes clamping devices, sealing mechanisms, conveyor belts, and cutters, and it is suitable for high-speed, explosion-proof, or clean environments in the food, pharmaceutical, and electronics industries.

[0003] When using a pneumatic packaging machine, the operator first places the items to be packaged on the worktable and adjusts the positioning device to ensure accurate product placement. Then, after starting the equipment, the control system issues commands according to a preset program. Solenoid valves control the flow of compressed air to the cylinders, driving clamping, sealing, or cutting mechanisms to complete the packaging action. Simultaneously, sensors monitor position and pressure in real time to ensure precise operation. After packaging, the finished product is conveyed out by a conveyor belt or manually removed, and the equipment automatically resets to await the next cycle. Existing packaging machines generally suffer from strong specialization and poor adaptability, only capable of packaging single products of specific specifications, shapes, or materials. The lack of flexible design leads to incompatibility issues for enterprises when iterating on products or diversifying production, resulting in high equipment idle rates, significant resource waste, and increased equipment procurement and maintenance costs. Utility Model Content

[0004] The purpose of this invention is to provide a multi-functional pneumatic packaging machine for sealing, in order to solve the problem that existing packaging machines can only package a single product and have poor adaptability.

[0005] To achieve the above objectives, the basic solution provided by this utility model is as follows: a multi-functional pneumatic packaging machine for sealing, comprising a frame, a vacuum pump box fixedly connected to the frame, a lifting bracket slidably connected to the frame, a rotating shaft rotatably connected to the lifting bracket, a housing fixedly connected to the rotating shaft, a heating strip fixedly connected to the housing, an L-shaped rod movably passing through the housing, an upper pressure strip provided on the L-shaped rod, the upper pressure strip being located directly above the heating strip, an arc-shaped through groove on the lifting bracket, an air pipe movably passing through the housing, an outlet of a control valve connected to the air pipe, an inlet of the control valve connected to the vacuum pump box, bolts provided on the housing, bolts movably passing through the arc-shaped through groove, a lifting mechanism for controlling the movement of the lifting bracket on the lifting bracket, and an extension component for extending the housing on the housing.

[0006] The principle and beneficial effects of this utility model are as follows: When packaging granules, powders, liquids and irregular items, a vertical packaging machine is required. The product to be packaged is placed on the machine frame, and then the machine box is raised to the required height through the lifting mechanism. Then, the bolts on the machine box are loosened and the machine box is rotated so that the bolts rotate around the pivot in the arc groove. The machine box is rotated to the required angle, and then the packaging opening of the product to be packaged is put on the air pipe. Then, the L-shaped rod retracts, driving the upper pressure strip to move towards the heating strip. The upper pressure strip and the heating strip clamp the packaging opening. The vacuum pump box is started, and the air in the packaging bag is extracted through the air pipe. The air pipe retracts back into the machine box, and the heating strip starts to heat and heat seal the packaging opening. When packaging long, boxed, or palletized products, a horizontal packaging machine is required. First, loosen the bolts on the machine casing, rotate the casing so that the bolts rotate around the pivot in the arc-shaped groove, and rotate the casing until it is horizontal to the ground. Then, tighten the bolts to secure the casing. Place the product to be packaged on the casing or its extension assembly, and then package the product. By rotating the bolts around the pivot in the arc-shaped groove, the casing's packaging structure can be rotated according to actual needs. The lifting mechanism can raise and lower the casing to the required height, increasing the variety of packaged products and thus enhancing the practicality of the packaging machine.

[0007] Option 2, a preferred option of the basic option, includes a lifting mechanism comprising a screw, which is threadedly connected to the frame and fixedly connected to the lifting bracket. The lifting bracket is equipped with a sliding component for moving the lifting bracket. When the height of the machine box needs to be adjusted, the screw is rotated to move the lifting bracket on the frame, thereby moving the machine box to the required height and increasing the practicality of the packaging machine.

[0008] Option 3, which is a preferred option of Option 2, includes two pulleys, each of which is fixedly connected to the lifting bracket. Two sliding grooves are opened on the frame, and each pulley is slidably connected to the sliding groove. When the lifting bracket moves on the frame, the pulleys convert the sliding friction between the lifting bracket and the frame into rolling friction, which can reduce the friction between the lifting bracket and the frame.

[0009] Option 4, which is a preferred option to Option 2, has casters fixed to the frame and a handle fixed to the screw; the casters provide flexible movement, steering and fixing functions; the handle allows for easier screw rotation, increasing the practicality of the packaging machine.

[0010] Option 5, an optimal choice from the basic option, includes an extension component comprising a pallet that is hinged to the chassis. Several limiting holes are located on both sides of the chassis. Two limiting rods are hinged to one end of the pallet, and the other end of each limiting rod is connected to a pin in a limiting hole. For products requiring tray fixation, when the volume of the packaged product becomes too large, the pallet is rotated to the required angle, and the limiting holes and rods limit the pallet's position. In horizontal packaging, this extends the area of ​​the chassis where the packaged product can be placed, increasing the practicality of the packaging machine.

[0011] Option 6, an optimal choice from the basic option, uses a three-way control valve with another outlet connected to an external gas pipe. The external gas pipe can be connected to oxygen, nitrogen, or carbon dioxide, allowing for vacuuming, oxygen filling, nitrogen filling, or carbon dioxide filling depending on the type of product being packaged, thus increasing the practicality of the packaging machine.
