Description

Technical Field

[0001] This utility model relates to the field of packaging machine technology, and in particular to a pneumatic liquid packaging machine. Background Technology

[0002] Pneumatic liquid packaging machines are mechanical devices that use compressed air as a power source and achieve automated control through pneumatic components. They are used for quantitative filling and packaging of liquid materials. The equipment uses compressed air as the main power source and achieves mechanical movement through pneumatic components such as cylinders and pneumatic valves, replacing traditional electric or hydraulic drive methods. It has advantages such as simple structure, fast response speed, and explosion-proof safety. It focuses on the processing of liquid materials and covers the complete packaging process from filling and sealing to finished product output. It is suitable for liquid product packaging in industries such as food, daily chemicals, and pharmaceuticals.

[0003] However, traditional pneumatic liquid packaging machines have a relatively simple structure. During filling, the filling nozzle directly contacts the inner wall of the packaging bag, and the filling range is relatively wide. Sticky liquid may cause blockage of the opening or sealing area of ​​the packaging bag, requiring manual cleaning or equipment adjustment, which increases downtime.

[0004] For example, in traditional pneumatic liquid packaging machines, the filling port is usually inside the packaging bag to transport the liquid. If the filling port is too large, the transport range will be too large, and the sticky liquid may spread around inside the packaging bag, affecting the sealing. If the filling port is too small, the packaging bag will not be stretched enough, and the shape of the packaging bag film material may not be full enough, affecting the sealing. Utility Model Content

[0005] This utility model discloses a pneumatic liquid packaging machine, which aims to solve the technical problems of traditional pneumatic liquid packaging machines. When using these machines, the structure is relatively simple, the filling port directly contacts the inner wall of the packaging bag during filling, the filling range is relatively wide, and the sticky liquid may cause blockage of the opening or sealing area of ​​the packaging bag, requiring manual cleaning or equipment adjustment, which increases downtime.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A pneumatic liquid packaging machine includes a housing and a storage tank disposed on the top outer wall of the housing. A conveying pipe is also disposed on one side of the housing. The machine further includes:

[0008] Support mechanism: The support mechanism includes a filling port disposed on the bottom outer wall of the conveying pipe. A rotating disk is disposed on the circumferential outer wall of the filling port. A fixed disk is disposed on the bottom outer wall of the rotating disk. A circular groove is formed inside the fixed disk. The rotating disk is disposed inside the circular groove. Five circular holes are also formed on the circumferential outer walls of the fixed disk and the rotating disk. A connecting rod is movably disposed inside each of the five circular holes. A movable block is disposed on one side outer wall of each of the five connecting rods.

[0009] Adjustment mechanism: The adjustment mechanism is disposed on the rotating disk;

During filling, the filling port and the support mechanism are inserted into the bag together. The five movable blocks contact the inner wall of the bag, providing full support and preventing the filling port from directly contacting the inner wall. This allows for clean and efficient liquid delivery during filling, ensuring the liquid reaches the precise location and preventing excessive liquid adhesion to the inner wall of the bag, thus facilitating subsequent sealing.

[0012] In a preferred embodiment, the adjusting mechanism includes five first arc-shaped grooves formed on one side of the outer wall of the rotating disk and five second arc-shaped grooves formed on one side of the outer wall of the fixed disk.

[0014] In a preferred embodiment, the top of the rotating disk is further provided with two rotating blocks, one end of the two rotating blocks is connected by a hinge, and the bottom outer wall of each of the two rotating blocks is provided with a first locking block. The top outer wall of the rotating disk is provided with two first locking slots, which cooperate with the two first locking blocks.

[0015] By using two hinged rotating blocks connected at the top of the rotating disk, along with two first locking blocks and two first locking slots on the rotating disk, the two first locking blocks can be inserted into the two first locking slots. Rotating the two rotating blocks controls the rotation of the rotating disk. The structure is simple and the steps are clear.

[0016] As described above, a pneumatic liquid packaging machine includes a housing and a storage tank mounted on the top outer wall of the housing. A conveying pipe is also provided on one side of the housing. The machine further includes: a support mechanism: the support mechanism includes a filling port mounted on the bottom outer wall of the conveying pipe. A rotating disk is mounted on the circumferential outer wall of the filling port. A fixed disk is mounted on the bottom outer wall of the rotating disk. A circular groove is formed inside the fixed disk, and the rotating disk is disposed inside the circular groove. Five circular holes are also formed on the circumferential outer walls of the fixed disk and the rotating disk. Five connecting rods are movably mounted inside each of the five circular holes, and a movable block is provided on one side outer wall of each of the five connecting rods; an adjustment mechanism: the adjustment mechanism is mounted on the rotating disk; and a sealing mechanism: the sealing mechanism is mounted on the housing. The pneumatic liquid packaging machine provided by this utility model has the technical effect of increasing the support mechanism, preventing liquid adhesion, and improving packaging efficiency.

[0024] The pneumatic liquid packaging machine disclosed in this utility model is mainly used in traditional pneumatic liquid packaging machines. The structure is relatively simple. During filling, the filling port directly contacts the inner wall of the packaging bag, and the filling range is relatively wide.

[0031] In practical use, the other end of the two rotating blocks 12 is respectively provided with a second slot and a second locking block (not shown in the figure), which are used to engage in a movable locking action. When one end of the two rotating blocks 12 is opened and fitted onto the outer circumference of the can opening, the locking action is then performed to close the block.

[0032] Specifically, by using two rotating blocks 12 connected by two hinges on the top of the rotating disk 13, and cooperating with two first locking blocks 20 and two first locking slots on the rotating disk 13, the two first locking blocks 20 can be locked into the two first locking slots, and the rotation of the two rotating blocks 12 can control the rotation of the rotating disk 13.
