[0035] Many specific details are set forth in the following description to provide a full understanding of the present invention. However, the present invention can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0036] In the description of this utility model, it should be noted that the terms "center," "upper," "lower," "left," "right," "vertical," "horizontal," "inner," and "outer," etc., indicating the orientation or positional relationship, are based on the orientation or positional relationship shown in the accompanying drawings and are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model. Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0037] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention.

[0038] like Figures 1-3As shown, this utility model provides a powder and liquid strip packaging machine, which includes a film feeding group 1, a film tension stepless adjustment group 2 for providing film feeding power, a color mark positioning group 3 for positioning the film, a film cutting group 5 for cutting the film, a longitudinal sealing group 6 for bending and heat sealing the film in the length direction, a transverse sealing group 7 for heat sealing the film in the width direction, a sealing and cooling group 8 for cooling the film, and a strip packaging cutting group 9 for cutting the strip packages;

[0039] The powder and liquid strip packaging machine also includes a frame 12, a feeding mechanism, a powder feeding group 4, and a liquid feeding group 10; the powder feeding group 4 and the liquid feeding group 10 can be switched to be connected to the feeding mechanism. The feeding mechanism includes a forming feeding pipe 11, the feeding end of which is detachably installed on the frame 12, and the discharging end of which passes through the longitudinal sealing group 6 and extends to the transverse sealing group 7. The powder feeding group 4 includes a spiral feeding pipe, which can be connected to the feeding end of the forming feeding pipe 11. The liquid feeding group 10 includes a liquid discharge pipe, which can be connected to the feeding end of the forming feeding pipe 11.

[0040] The film feeding group 1, the film tension stepless adjustment group 2, the color mark positioning group 3, the film slitting group 5, the longitudinal sealing group 6, the transverse sealing group 7, the sealing and cooling group 8, and the strip cutting group 9 are all set inside the frame 12, and the film passes through the film feeding group 1, the film tension stepless adjustment group 2, the color mark positioning group 3, the film slitting group 5, the longitudinal sealing group 6, the transverse sealing group 7, the sealing and cooling group 8, and the strip cutting group 9 one by one.

[0041] In this embodiment, the powder and liquid strip packaging machine, through the switchable powder feeding group 4 and liquid feeding group 10, enables the machine to package both solid powders and liquid materials. This avoids the limitations of traditional strip packaging machines, which often only package one type of material, resulting in insufficient versatility, underutilization of the equipment, and resource waste. This application achieves multi-functionality of the strip packaging machine through the switchable powder feeding group 4 and liquid feeding group 10, expanding its applicable product range and applicability. Furthermore, by detachably mounting the inlet end of the forming feeding tube 11 to the slot 121 of the frame 12, this single-row powder and liquid strip packaging machine can meet the needs of experimental production, small-batch trial production, and small-scale product customization. It can also be expanded into a multi-row strip packaging machine by adding a forming feeding tube 11 to increase production efficiency and adapt to the needs of large-scale production.

[0042] Furthermore, this powder and liquid strip packaging machine, through its film feeding group 1 and film tension stepless adjustment group 2, enables the mechanical, rapid, and automatic adjustment of the film winding speed as it enters the machine. This ensures constant tension after the film is tightened, effectively protecting the film, extending its lifespan, and preventing breakage during production. Additionally, when the film passes through the color mark positioning group 3, this group detects the specific color mark position and the breakage point on the film, ensuring bag-forming stability and facilitating the removal of defective products with broken film.

[0043] In a preferred embodiment, the continuously variable film tension adjustment assembly 2 includes an adjustment base, a swingable gravity roller, a power roller, a continuously variable transmission (CVT), and an upper pressure roller. The adjustment base is disposed within the frame 12. The power roller, CVT, and upper pressure roller are all mounted on the adjustment base. The power roller is connected to the output end of the CVT to adjust the film winding speed. The upper pressure roller is positioned above the power roller to flatten the film. The gravity roller is hinged to the adjustment base. In this embodiment, the mechanical, rapid, and automatic adjustment of the film winding speed is achieved through the connection of the power roller to the CVT and the gravity roller, which swings automatically with the film winding, to maintain a constant film tension.

[0044] In one embodiment, the film slitting assembly 5 includes a slitting base, a film slitting knife, and a film forming roller; the slitting base is hinged to the frame 12, the film slitting knife and the film forming roller are both disposed on the slitting base, and a cylinder is fixedly disposed on the slitting base, the output end of the cylinder being connected to one end of the slitting base to control the rotation of the slitting base.

[0045] In this embodiment, the powder and liquid strip packaging machine, through the setting of the film slitting group 5, enables the strip packaging machine to slit the stretched and straightened roll film into multiple columns by means of the film slitting blade when it needs to be expanded into multiple columns. The film slitting blade is rotatably mounted on the slitting base so that the roll film is divided into multiple columns by the slitting blade. The film slitting blade is driven by a cylinder to achieve quick blade disassembly and replacement.

[0046] See Figure 4 The longitudinal sealing assembly 6 includes a servo rocker arm drive mechanism 7, a longitudinal sealing base 62, a longitudinal sealing movable mechanism 63, and a cylinder drive mechanism 64. The servo rocker arm drive mechanism 7 is connected to the longitudinal sealing base 62 to drive the longitudinal sealing base 62 to rotate, and the cylinder drive mechanism 64 is connected to the longitudinal sealing movable mechanism 63 to adjust the horizontal position of the longitudinal sealing movable mechanism 63.

[0047] In this embodiment, the longitudinal sealing assembly 6 bends the roll film into a strip-shaped packaging bag and heat-seals the roll film along its length. The movable structure of the longitudinal sealing assembly 6 is moved by an adjustment cylinder and can be disassembled and rotated on one side, thus facilitating manual adjustment of the roll film forming, cleaning, and maintenance of the device. After the adjustment cylinder is reset, the moving distance of the assembly remains only 2mm, thereby further ensuring the operating speed of the equipment.

[0048] like Figure 5 As shown, the horizontal sealing assembly 7 includes a horizontal sealing base 71, a horizontal sealing upper module 72, and a film pulling drive mechanism 73; the horizontal sealing upper module 72 is connected to the horizontal sealing base 71 and can move in the horizontal direction, the horizontal sealing base 71 is connected to the film pulling drive mechanism 73, and the film pulling drive mechanism 73 can drive the horizontal sealing base 71 and the horizontal sealing upper module 72 to move in the vertical direction.

[0049] In this embodiment, the strip film formed by the longitudinal sealing assembly 6 enters the transverse sealing assembly 7 for sealing. The strip packaging bag is then heat-sealed in the width direction and filled with powder or liquid material. The transverse sealing assembly 7 can be driven and adjusted vertically by the film pulling drive mechanism 73, thereby adjusting the length of the strip package. After heat sealing, the strip package needs to be cooled by the sealing and cooling assembly 8. The sealing and cooling assembly 8 is equipped with a strip package cooling circulation air blowing pipe, which can be adjusted and rotated to allow for position adjustment according to different strip package specifications, ensuring effective air blowing and cooling.

[0050] See Figure 6 In a preferred embodiment, the strip package cooled by the sealing and cooling group 8 finally passes through the strip package cutting group 9. After adjusting the appropriate cutting length with a handle, it forms a beautifully packaged strip package with rounded corners, making it easy to tear. The cut waste edges, defective products, and qualified products are transported to corresponding locations for recycling through different channels. The strip package cutting group 9 includes a rounded corner cutter assembly 91, a bag length adjustment assembly 92, a finished product discharge assembly 93, and a defective product discharge assembly 94. The rounded corner cutter assembly 91 is located below the sealing and cooling group 8. The bag length adjustment assembly 92 is preferably an infrared sensor to detect the strip package length and adjust the strip package length through the rounded corner cutter assembly 91.

[0051] Furthermore, the frame 12, used for mounting the feed end of the forming feed tube 11, is provided with multiple slots 121, which can engage with the feed end of the forming feed tube 11. The longitudinal sealing assembly 6 has pre-reserved mounting positions for the longitudinal sealing base 62 and the longitudinal sealing movable mechanism 63 corresponding to the slots 121, and the transverse sealing assembly 7 has pre-reserved mounting positions for the transverse sealing upper module 72 corresponding to the slots 121. The feed end of the forming feed tube 11 includes a funnel-shaped opening, which engages with the frame 12.

[0052] In this embodiment, the frame 12 for installing the feeding end of the forming feed tube 11 is provided with multiple slots 121, and each slot 121 in the longitudinal sealing assembly 6 and the transverse sealing assembly 7 is reserved with a longitudinal sealing base 62, a longitudinal sealing movable mechanism 63, and a transverse sealing upper module 72. This allows the strip packaging machine to quickly install and remove multiple forming feed tubes 11 through the slots 121 when it is expanded to multiple rows, and to set longitudinal sealing bases 62, longitudinal sealing movable mechanisms 63, and transverse sealing upper modules 72 for each forming feed tube 11 to package the formed strips.

[0053] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0054] The above embodiments only illustrate several implementation methods of this utility model, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
