[0008] A servo clamping drive source, rotatably mounted on the receiving and lifting platform, is used to provide clamping driving force; and

[0009] The clamping arms are movable and mirror images of each other on the receiving and lifting platform; the servo clamping drive source can drive adjacent clamping arms to move closer or further apart.

[0010] Furthermore, the servo lifting drive source and the servo clamping drive source adopt the same structural configuration; the servo lifting drive source includes a servo drive motor rotatably mounted on the clamping bracket; the output end of the servo drive motor is connected to a synchronous belt assembly.

[0011] The receiving and lifting platform is movably connected to the clamping bracket on one side via symmetrically arranged guide shafts; the bottom of the receiving and lifting platform is provided with lifting rails; one end of the lifting rails is detachably connected to the synchronous belt assembly; the top surface of the receiving and lifting platform is smooth.

[0012] The clamping arm includes a C-shaped base; one end of the C-shaped base is movably connected to the material receiving and lifting platform via a linear rail, and the other end is provided with a sheet-like clamping plate.

[0013] Furthermore, the packaging bag forming device includes a packaging bag forming support mounted inside the frame; along the length of the packaging bag forming support, there are sequentially arranged a film pulling and cutting mechanism, a dotted line punching mechanism, a handle hole punching mechanism, a coding mechanism, a punching mechanism, an online hot-sealing bag making mechanism, a film pulling mechanism, and a film correction mechanism; a constant tension unwinding mechanism is rotatably provided at the bottom of the packaging bag forming support; the film pulling and cutting mechanism is used to form and cut the packaged bag; the dotted line punching mechanism is used to open the easy-tear line on the packaged bag; the handle hole punching mechanism is used to punch and form a handle hole at one end of the packaged bag; the coding mechanism is used to print information on the packaged bag; the punching mechanism is used to punch holes in the packaged bag; the online hot-sealing bag making mechanism is used to form and heat-seal one end of the packaged bag; the film pulling mechanism is used to pull the film and convey it forward; the film correction mechanism is used to ensure that the roll film does not deviate during the output process.

[0014] Furthermore, the pet pants forming packaging device includes a bag opening device located on one side of the packaging bag forming device for puncturing one end of the formed packaging bag; a heat sealing device located directly below the bag opening device for heat sealing the other end of the packaging bag; a feeding conveyor device vertically inserted into the frame on one side of the clamping mechanism; a pushing mechanism movably provided between the feeding conveyor device and the bag opening device; a bag feeding mechanism rotatably provided in front of the pushing mechanism; and a shaping mechanism provided between the heat sealing device and the packaging bag forming support.

[0015] The heat sealing device is provided with a tail material adsorption assembly on one side; the tail material adsorption assembly includes an adjustable platform-shaped adsorption hood mounted on the heat sealing device; a fan is connected to the bottom pipe of the adsorption hood.

[0016] Compared with the prior art, the present invention has the following beneficial effects:

[0017] 1) In the complex process of pet trouser packaging, traditional manual handling or simple mechanical conveying methods are not only inefficient but also prone to errors and instability. This invention ingeniously incorporates a liftable clamping mechanism between the packaging bag forming device and the pet trouser forming and packaging device, completely changing this situation. The clamping mechanism, like a well-trained robot, precisely and efficiently holds the pet trousers output from the pet trouser forming and packaging device, then smoothly lifts them vertically to a predetermined height, completing the automated transfer from production to packaging in one go. This innovative design greatly reduces manual intervention, significantly lowers labor costs, and effectively avoids various problems caused by manual operation, ensuring that each pet trouser is accurately delivered to its designated location. This lays a solid foundation for perfect coordination with the packaging bag, thereby comprehensively improving packaging efficiency and product quality, leading the pet trouser packaging industry to a new level of automation.

[0018] 2) The servo lifting drive source and the servo clamping drive source adopt the same sophisticated structure, both consisting of a servo drive motor paired with a synchronous belt assembly. The servo drive motor, with its high precision, high response speed, and excellent control performance, acts like a precise commander, accurately controlling the clamping force of the clamping arm and the lifting height and speed of the receiving platform. The synchronous belt assembly, with its significant advantages of smooth transmission, high precision, and low noise, stably and accurately transmits the power of the servo drive motor to the receiving platform and clamping arm, ensuring that their movements are perfectly synchronized. One side of the receiving platform is flexibly connected to the clamping bracket via symmetrically arranged guide shafts. These guide shafts act like sturdy rails, providing stable guidance for the lifting platform's movement, ensuring stability during lifting and preventing deviation or swaying. One end of the lifting rail is detachably connected to the synchronous belt assembly, a thoughtful design that greatly facilitates equipment maintenance and component replacement. The top of the receiving platform is smoothed, significantly reducing friction with the pet pants and preventing any wear or damage during handling. The C-shaped base of the gripping arms is smoothly connected to the receiving and lifting platform via linear guides. The unique design of the linear guides gives the gripping arms smooth and precise movement, allowing them to quickly and accurately move closer or further apart under the drive of the servo gripping drive source, reliably gripping or releasing the pet pants. In addition, the plate-shaped clamp at the other end of the C-shaped base conforms to the unique shape of the pet pants, applying force evenly to ensure that the pet pants remain stable throughout the handling process, without falling or deforming.

[0019] 3) The various components of the packaging bag forming device are arranged in an orderly manner along the length of the packaging bag forming support, jointly constructing a highly efficient and integrated packaging bag forming production line. The constant tension unwinding mechanism acts like a stable material feeder, continuously and steadily releasing the packaging film, ensuring constant tension during the conveying process. This prevents film deformation or breakage due to tension fluctuations, providing a continuous supply of high-quality raw materials for subsequent processing steps. The film pulling mechanism and film correction mechanism work closely together, like tacit partners, precisely controlling the film conveying length to ensure that each packaging bag is of consistent size, significantly improving product consistency and standardization. The film pulling and bag cutting mechanism, with its precise cutting technology, shapes and cuts the film, ensuring that the shape and size of the packaging bag perfectly match the requirements. The easy-tear line created by the dotted line mechanism fully considers the consumer experience, making it easier and more convenient for consumers to open the packaging bag. The handle hole punched by the handle hole mechanism gives the packaging bag excellent portability. The coding system acts like a meticulous recorder, accurately printing key product information such as brand logos, production dates, and shelf-life on the packaging bags, providing strong support for product traceability and market sales. The punching system performs punching operations according to the specific needs of the product, meeting diverse packaging requirements. The online heat-sealing system heat-seals one end of the packaging bag, rigorously protecting its airtightness and comprehensively ensuring the quality and safety of the packaged product. This highly integrated design condenses multiple packaging bag forming processes into a single device, significantly reducing the equipment's footprint, substantially improving production efficiency, and effectively reducing equipment maintenance costs and operational complexity, creating greater economic benefits for enterprises.

[0020] 4) The components of the pet trouser forming and packaging device work together like a closely coordinated team, composing a symphony of efficient packaging. The bag-opening device, like a nimble bag-opening expert, precisely and accurately punctures one end of the formed packaging bag, carefully paving the way for the filling of the pet trousers. The heat-sealing device, located directly below the bag-opening device, immediately heat-seals the other end of the packaging bag after the pet trousers are successfully placed inside, ensuring the packaging is airtight. The feeding conveyor, vertically inserted on the frame, acts like a continuous conveyor belt, stably and continuously transporting pet trousers, providing a constant supply of raw materials for the packaging process. The pushing mechanism moves flexibly between the feeding conveyor and the bag-opening device, accurately pushing the pet trousers from the feeding conveyor into the packaging bag at the bag-opening device, smoothly achieving automatic filling of the pet trousers. The bag-feeding mechanism, rotatably positioned directly in front of the pushing mechanism, acts like a helpful assistant, assisting the pushing mechanism in smoothly feeding the pet trousers into the packaging bag, significantly improving the filling success rate. The shaping mechanism, positioned between the heat-sealing device and the bag-forming support, meticulously shapes the bags after the pet pants are inserted, resulting in a smoother and more aesthetically pleasing product appearance and significantly enhancing its market competitiveness. The close collaboration between these mechanisms perfectly automates and simplifies the entire packaging process, from opening the bag, filling the pants, heat-sealing to shaping, greatly improving the production efficiency and quality of pet pants packaging and setting a new benchmark for the industry.
