Description

Technical Field

[0001] The utility model relates to a high-speed liquid packaging machine with a reasonable structure. Background Art

[0002] In a high-speed liquid packaging machine, by adopting a turntable conveying mechanism, the work of making a packaging film into a packaging bag and filling and packaging materials into the packaging bag is synchronously completed during the process of conveying the packaging film, thereby realizing high-speed full-automatic packaging, reducing the packaging cost and labor intensity, and improving the production efficiency. For example, a packaging machine disclosed in a Chinese patent document with the publication number CN112607075A and the name "Horizontal Pump Valve High-Speed Liquid Packaging Machine" includes a machine frame and a film feeding device, a packaging bag forming device, a longitudinal sealing device, a filling device, and a sealing device which are respectively installed on the machine frame and arranged in sequence along the conveying direction of the packaging material. The filling device further includes a rotatable storage tray and a material quantitative output mechanism. The rotatable storage tray is installed on a rotating frame. The material quantitative output mechanism includes at least one material quantitative output device. The material quantitative output device includes a mounting seat and at least one horizontal material quantitative output unit. The horizontal material quantitative output unit includes a pumping and feeding pump, a three-way valve, and a three-way valve communication state conversion mechanism. This packaging machine includes a rotating frame and a longitudinal sealing device arranged outside the rotating frame and rotating around the rotating frame. The rotating frame and the longitudinal sealing device are driven by a driving mechanism. The driving mechanism uses a driving device (usually a servo motor) to drive the rotating frame and the longitudinal sealing device to rotate through a cam divider and a gear transmission mechanism respectively. Due to its relatively complex structure and the need for the two (rotating frame, longitudinal sealing device) to be synchronized, the precision requirements of the components used are high, making it difficult to reduce the cost. Once damaged, it is very troublesome to repair and replace, and it has high energy consumption and it is also difficult to improve the working efficiency.

[0003] In order to improve the working efficiency, a liquid filling mechanism of a high-speed packaging machine disclosed in a Chinese patent document with the publication number CN117864515A and the name "Liquid Filling Mechanism of a High-Speed Packaging Machine with a Reasonable Structure" includes a machine frame, a hopper, a plurality of material quantitative distribution units, a plurality of filling devices, and a rotating frame. The material quantitative distribution unit includes a servo motor and a rotor pump. The servo motor and the rotor pump are respectively installed on the rotating frame. The output shaft of the servo motor is connected to the transmission shaft of the rotor pump. The discharge port is connected to the inlet of the rotor pump through a feed pipe, and the outlet of the rotor pump is connected to the inlet of the filling device through a feeding pipe.

[0004] However, the applicant found that although the above high-speed packaging machine has made some improvements to the liquid filling part, its structure is still very complex, with too many components. Moreover, the support mechanism (its rotating frame) and the longitudinal sealing device still use an existing driving mechanism to drive, and the structure is very complex. Therefore, the whole structure still has problems such as unreasonable structure, too many components, too high equipment cost, and high energy consumption. Summary of the Invention

[0005] The object of the present utility model is to provide a high-speed liquid packaging machine with a reasonable structure. This high-speed liquid packaging machine with a reasonable structure has a reasonable structure and can effectively reduce energy consumption and equipment costs.

The hopper installed on the support mechanism cooperates with the liquid filling mechanism through the liquid filling mechanism to complete the filling work of the flexible packaging container located in the longitudinal sealing device. During the filling work process, the liquid filling mechanism and the longitudinal sealing device always remain relatively stationary in the horizontal direction; the liquid filling mechanism includes a liftable platform, a lifting unit, a controllable reversing valve, a first cylinder, a plurality of filling heads, and a plurality of material pumps. The lifting unit is installed on the support mechanism, and the lifting unit has a lifting action end that can move in the vertical direction.

The controllable reversing valve has a rotatable valve core, and a control swing rod is installed at one end of the rotatable valve core. The rear end of the first cylinder is hinged to the support mechanism, and the first piston rod of the first cylinder is connected to the control swing rod. In this way, the liquid filling mechanism can well complete each action, its structure is optimized, the number of components is greatly reduced, and the energy consumption is effectively reduced.

[0007] In one solution, the support mechanism includes a support frame, the support frame is installed on the frame, the hopper and the liquid filling mechanism are respectively installed on the support frame, and the longitudinal sealing device rotates intermittently around the support frame. When the longitudinal sealing device stops moving, the liquid filling mechanism completes the filling work.

[0008] In another solution, the support mechanism includes a rotating frame and a rotating frame driving mechanism. The rotating frame is rotatably mounted on the machine frame, and the rotating frame driving mechanism is mounted on the machine frame and drives the rotating frame to rotate.

The first gear transmission unit includes an output gear and a passive gear. The output gear is mounted on the first output shaft of the first driving unit, and the passive gear is mounted on the rotating shaft of the rotating frame. The longitudinal sealing device rotates continuously around the support mechanism.

By using the first driving unit to drive the rotating frame to rotate through the first gear transmission unit, the structure of the driving unit can be simplified, and the loss of energy during transmission can be reduced.

[0009] In one solution, the first gear transmission unit further includes a plurality of intermediate gears. The first driving unit drives the rotating frame to rotate through the output gear, a plurality of intermediate gears, and the passive gear in sequence.

[0010] In another solution, the output gear and the passive gear are directly meshed.

[0011] In one solution, the first driving unit is a first servo motor, and the first output shaft is the output shaft of the first servo motor.

And by improving the liquid filling mechanism, the number of components is reduced, further reducing energy consumption and the cost of the equipment. BRIEF DESCRIPTION OF THE DRAWINGS

[0039] As Figure 3 、 4 shown in the figure, in an alternative embodiment of the present application, the output gear 3021 and the passive gear 3022 are directly meshed. Figure 7 、 8 For the embodiment shown Figure 9 and the embodiment shown are the same.

[0040] As Figure 3 、 4 shown in the figure, in an alternative embodiment of the present application, the first driving unit 301 is a first servo motor, and the first output shaft is the output shaft of the first servo motor. Figure 10 For the embodiment shown are the same.

[0041] In an alternative embodiment of the present application, the first driving unit 301 includes a first servo motor and a first reduction gearbox. The output shaft of the first servo motor is connected to the first reduction gearbox, and the first output shaft is the output shaft of the first reduction gearbox.

[0042] As Figure 3 , 4 shown, in an alternative embodiment of the present application, the rotary rack driving mechanism 3 is disposed in the middle of the frame 1. Figure 9 The same applies to the embodiment shown.

[0043] As Figure 5 shown, in an alternative embodiment of the present application, the rotary rack driving mechanism 3 is disposed at the bottom of the frame 1. Figure 7 , 8 The same applies to the embodiment shown. Figure 10 The embodiments shown in Figure 12 are the same.

[0044] As Figure 1 , 2 shown, in an alternative embodiment of the present application, the high-speed liquid packaging machine further includes a second servo motor (not visible in the figure) and a second gear set (not visible in the figure). The second servo motor drives the longitudinal sealing device 6 to rotate around the rotary rack 2 through the second gear set. Since its structure still adopts the structure of the prior art and there is no improvement, it will not be described in detail here.

[0045] As Figure 1 , 2 shown, in an alternative embodiment of the present application, the high-speed liquid packaging machine further includes a film feeding mechanism 7. The film feeding mechanism 7 is installed on the frame 1 and the film feeding mechanism 7 is located on the lower side of the frame 1.

[0046] As Figure 1 , 2 shown, in an alternative embodiment of the present application, the high-speed liquid packaging machine further includes a sealing mechanism 8 and a shearing mechanism 9. The sealing mechanism 8 and the shearing mechanism 9 are respectively installed on the frame 1 and the sealing mechanism 8 and the shearing mechanism 9 are located outside the outlet of the longitudinal sealing device 6.

[0047] As Figure 1 , 2 shown, in an alternative embodiment of the present application, the high-speed liquid packaging machine further includes a bag feeding mechanism 10 and a finished product discharging mechanism 11. The bag feeding mechanism 10 and the finished product discharging mechanism 11 are respectively installed on the frame 1 and the bag feeding mechanism 10 and the finished product discharging mechanism 11 are located outside the sealing mechanism 8. The bag feeding mechanism 10 is disposed above the finished product discharging mechanism 11.

[0048] The working process of this embodiment will be introduced below in conjunction with Figures 1-4 :

[0049] The film feeding mechanism 7 feeds out the film, folds it in half and then sends it into the longitudinal sealing device 6. The longitudinal sealing device 6 longitudinally seals the film and moves with the film (the longitudinal sealing device 6 continuously rotates around the rotating frame 2, thus driving the film to move), forming multiple soft packaging containers with open tops. The liquid filling mechanism 5 fills each soft packaging container. After filling, each soft packaging container enters the sealing mechanism 8 in sequence. The sealing mechanism 8 seals the open tops of each soft packaging container. The cutting mechanism 9 cuts each soft packaging container to make soft packaging finished products, and then the bag feeding mechanism 10 sends the soft packaging finished products above the finished product discharging mechanism 11 in sequence and drops them. The soft packaging finished products are discharged through the finished product discharging mechanism 11.

[0050] It should be noted that in this embodiment, the longitudinal sealing device 6 rotates continuously, while the rotating frame 2 rotates reciprocally. That is to say, during the process of the liquid filling mechanism 5 completing the entire filling work, the rotating frame 2 and the longitudinal sealing device 6 rotate synchronously by an angle; after the filling work is completed, the longitudinal sealing device 6 continues to rotate, while the rotating frame 2 rotates reversely by the same angle, and then the rotating frame 2 rotates synchronously with the longitudinal sealing device 6 by an angle again. During the synchronous rotation process, the liquid filling mechanism 5 completes the entire filling work again.

[0051] The following introduces the process of the filling work:

[0052] First, the first piston rod of the first air cylinder 504 drives the control swing rod 5031 to swing, so that the rotatable valve core rotates, and the hopper 4 is respectively communicated with each material pump 506. Each material pump 506 respectively pumps out the liquid material in the hopper 4; then the first piston rod of the first air cylinder 504 drives the control swing rod 5031 to swing reversely, so that the rotatable valve core rotates reversely, the hopper 4 is disconnected from all the material pumps 506, and each material pump 506 is respectively communicated with the corresponding filling head 505. Each material pump 506 respectively sends the liquid material to the corresponding filling head 505 for filling. At the beginning of filling, the lifting unit 502 drives the liftable platform 501 to descend, so that the filling head 505 is inserted into the opening of the lower soft packaging container, and then the filling head 505 fills. After the filling material is completed, the lifting unit 502 drives the liftable platform 501 to rise back to the original position, so that the filling head 505 leaves the lower soft packaging container, thus completing the entire process of one filling work.

[0053] In addition, it should be noted that for the specific embodiments described in this specification, the names of their respective parts and the like may be different. Any equivalent or simple changes made according to the structure, features, and principles described in the inventive concept of this utility model patent are included within the protection scope of this utility model patent.
