Description

A heat sealing and slitting machine for packaging bags Technical Field

[0001] This utility model relates to the field of packaging technology, and more specifically, to a heat-sealing and slitting machine for packaging bags. Background Technology

[0002] In the production process of packaging bags, the formed packaging bag materials need to be heat-sealed and cut.

[0003] Chinese utility model patent with announcement number CN222610609U describes a heat sealing and cutting device for a plastic flexible packaging bag making machine, including a support member and a cutting member. The support member includes a slide bar frame, an opening and closing hydraulic rod is vertically fixed on the top surface of the slide bar frame, and a cutting groove seat is horizontally fixed on the bottom top surface of the slide bar frame. A first translation hydraulic rod is horizontally fixed on one side of the bottom top surface of the slide bar frame, and a brush seat is vertically fixed at the output end of the first translation hydraulic rod.

[0004] The problem addressed by the above solution is that after the sealing and cutting blade frequently comes into contact with the plastic bag, some plastic residue generated during the heat-cutting process remains on its cut surface. Continuous heat-cutting work causes more and more residue to accumulate at the blade, which not only affects the heat transmission during the sealing process, resulting in incomplete sealing, but also causes the residue to stick to the plastic bag during sealing, resulting in particulate stains on the cut plastic bag. The presence of particulate stains on the sealing and cutting blade affects the sealing effect of the packaging bag.

[0005] This application provides another technical solution to this technical problem. Summary of the Invention

[0006] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a heat sealing and slitting machine for packaging bags.

A second mold is slidably driven to slide on the frame by a second drive component. Both the first and second molds have relief grooves into which the cutter slides. A cleaning brush is fixedly provided on the side wall of the relief groove of the first mold.

[0009] The present invention is further configured such that: the cutter includes a base portion and a plurality of toothed portions, the plurality of toothed portions being spaced apart along the length direction of the base portion, and a protruding tooth being formed between two adjacent toothed portions.

[0010] The present invention is further configured such that the protruding teeth are arranged at an angle.

[0011] The present invention is further configured such that: the tooth portion is formed with tooth grooves, and the cleaning brush is provided at intervals of several, and the several cleaning brushes are used to slide into the several tooth grooves respectively.

[0012] The present invention is further configured such that: the first mold and the second mold are respectively connected to the first slide and the second slide, and the frame is fixed with a guide rod that passes through the first slide and the second slide.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. In the description of the present utility model, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing the present 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. Therefore, they should not be construed as limitations on the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0023] As shown in Figures 1, 2, and 3, this application provides a heat-sealing and sliding machine for packaging bags, including a frame 1, a first mold 2, a second mold 3, and a cutter that slide together. Heating rods are installed inside the first mold 2 and the second mold 3. When the first mold 2 and the second mold 3 clamp the packaging bag, they can use pressure and heat to heat-seal the bag. The cutter is fixedly mounted on a slide block 4, the first mold 2 is slidably mounted on the slide block 4, and the second mold 3 is fixedly mounted on a slide block 5. The frame 1 is fixed... A guide rod 6 is provided that runs through slide 4 and slide 5. The guide rod 6, in cooperation with slide 4 and slide 5, can increase the stability of slide 4 and slide 5 when sliding. Both die 2 and die 3 are formed with relief grooves for the cutter to slide into. A spring 14 is provided between slide 4 and die 2. The two ends of the spring 14 are connected to slide 4 and die 2. In the initial state, the relief groove of die 2 will abut against the cutter under the action of the spring 14.

[0024] As shown in Figures 1, 2, and 3, the frame 1 is equipped with a drive component one and a drive component two. Drive component one and drive component two respectively include cylinder one 7 and cylinder two 8 fixed to the frame 1. The piston ends of cylinder one 7 and cylinder two 8 are fixedly connected to slide one 4 and slide two 5 respectively. When the packaging bag is conveyed between mold one 2 and mold two 3, cylinder one 7 and cylinder two 8 are simultaneously actuated. Mold one 2 and the cutter move closer to mold two 3 until mold one 2 and mold two 3 clamp the packaging bag and heat seal it. At this time, cylinder two 8 stops actuating, while cylinder one 7 continues actuating. The cutter slides into the relief groove of mold two 3, and spring 14 is deformed by force to ensure relative sliding between mold one 2 and the cutter until the cutter enters the relief groove of mold two 3 and cuts the packaging bag, completing the processing of the packaging bag.

[0025] As shown in Figures 3 and 4, the cutter includes a base part 9 and several toothed parts 10. The toothed parts 10 are spaced apart along the length of the base part 9, so that a protruding tooth 12 is formed between two adjacent toothed parts 10. The protruding tooth 12 is inclined. When the cutter cuts, the inclined protruding tooth 12 first contacts the packaging bag. The inclined protruding tooth 12 can reduce the contact area between the protruding tooth 12 and the packaging bag, making it easier to cut the packaging bag. At the same time, the toothed parts 10 are formed with tooth grooves 11. After the packaging bag is cut, the plastic residue generated by the cutting will adhere to the toothed parts 10 and into the tooth grooves 11. A cleaning brush 13 is fixedly provided on the side wall of the relief groove of the mold 2, and several cleaning brushes 13 are spaced apart. The several cleaning brushes 13 are used to slide into the several tooth grooves 11 respectively. In this embodiment, the cleaning brush 13 is a wire brush, so that it is not affected by the heat of the mold 2.

[0026] After the cutter finishes cutting the packaging bag, it actuates cylinders 7 and 8, causing mold 2 and the cutter to reset with mold 3. During this process, the cutter moves from the clearance groove of mold 3 into the clearance groove of mold 2. The cleaning brush 13 contacts the cutter to clean the plastic residue adhering to the tooth groove 11, reducing the impact on subsequent heat sealing and cutting, and improving processing quality.

[0027] In summary, the heat sealing and slitting machine provided in this embodiment uses a cleaning brush 13 to remove plastic residues adhering to the sidewalls of the tooth groove 11, reducing the impact on subsequent heat sealing and slitting and improving processing quality.

[0028] The above description is merely a preferred embodiment of this utility model. The protection scope of this utility model is not limited to the above embodiments. All technical solutions falling within the scope of this utility model's concept are protected. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of this utility model should also be considered within the protection scope of this utility model.
