[0018] The technical effects and advantages of the present invention are as follows:

[0019] 1. In the present invention, the spiral effect of the two nuts and screws on both sides makes it easy to regulate the top side of the packaging bag. The pinch rolls approach each other while moving downward inside the chute through the protruding rod. The two pinch rolls gradually approach the packaging bag during the downward movement process. At this time, the two pinch rolls facilitate temporary clamping of the mouth of the packaging bag and reduce the diameter of the mouth of the packaging bag. The protruding rod moves the top end of the movable plate downward. The two movable plates make the inner ends of the two bottom plates gradually rotate downward during the rotation process, and the bottom end of the packaging bag gradually moves downward with the rotation of the bottom plate.

The reaction force of the first slide rail against the rollers causes the rollers to move the central rod upward on the surface of the vertical rod, and as the central rod moves upward, it presses the spring on the surface of the vertical rod, and the elastic force of the spring prevents the inner bottom surface of the half rings from directly contacting the top surface of the first slide rail, and the half rings roll on the surface of the first slide rail through the rollers, thereby avoiding damage caused by sliding friction between the half rings and the first slide rail and improving the service life of the entire rolling structure.

[0021] 3. In the present invention, when the pinch roll moves downward inside the chute through the protruding rod, the protruding rod moves the gear downward at the same time, and the gear and the teeth of the helical rack mesh, so that the gear rotates during the downward movement process. The gear rotates the pinch roll simultaneously through the protruding rod, and the two pinch rolls rotate toward each other on both sides of the packaging bag, that is, the left pinch roll rotates counterclockwise, and the right pinch roll rotates clockwise, so that the two pinch rolls rotating toward each other do not push out both sides of the top of the packaging bag during the rotation process of the two pinch rolls rotating toward each other, and at this time, the diameter of the opening of the packaging bag can be gradually reduced during the approach process of the two pinch rolls approaching each other, and the two pinch rolls approaching each other can smoothly clamp the opening of the top of the packaging bag, and the opening of the top of the packaging bag can always be upward during the contact process of the two pinch rolls rotating toward each other with the packaging bag.

[0022] 4. The sliding rod design of the present invention enables the device to pack the items into the packaging bags and transport the packaging bags more smoothly without causing the packaging bags to leak. The items are packaged cyclically and continuously, which greatly improves the packaging efficiency and ensures the safety of the packaging.

When the packaging structure moves on the circulation line, the packaging structure moves on the first slide rail 1 via the rolling structures at both ends of the half ring 4. By placing the half ring 4 on the top of the first slide rail 1, the bottom surfaces of the rollers 7 on both ends of the half ring 4 first come into contact with the top surface of the first slide rail 1, the weight of the rolling structure and the packaging structure is placed on the two half rings 4, and the weight on the half rings 4 acts directly on the first slide rail 1 through the rollers 7. The reaction force of the first slide rail 1 against the rollers 7 causes the rollers 7 to move the central rod 11 upward on the surface of the vertical rod 10, and while moving upward, the central rod 11 presses the spring 12 on the surface of the vertical rod 10, and the elastic force of the spring 12 prevents the inner bottom surface of the half ring 4 from directly contacting the top surface of the first slide rail 1. In addition, the half ring 4 rolls on the surface of the first slide rail 1 through the rollers 7, thereby avoiding damage caused by sliding friction between the half ring 4 and the first slide rail 1 and improving the service life of the entire rolling structure.

[0029] As shown in FIGS. 1 and 2, two chutes 13 are symmetrically drilled on both sides of the surface of the limiting bracket 5, and the distance between the tops of the two chutes 13 is greater than the distance between the bottoms of the two chutes 13. The packaging structure includes two pinch rolls 14 corresponding to the two chutes 13, and protruding rods 15 are provided at both ends of the pinch rolls 14. The pinch rolls 14 slide into the chutes 13 on one side of the two limiting brackets 5 through the protruding rods 15 at both ends. An electric heating device is provided inside the pinch rolls 14, and the pinch rolls 14 are connected to an external battery. The packaging bag 6 is set as a vinyl packaging bag, and as the two pinch rolls 14 gradually move downward, they move downward inside the chute 13 through the protruding rod 15, and gradually approach each other as they move downward until they can continue to clamp the top opening of the packaging bag 6, and the battery energizes the electric heating device in the pinch roll 14, at which time the energized electric heating device generates heat and acts on the top opening of the packaging bag 6 through the pinch roll 14, so that the contact position between the surface of the packaging bag 6 and the heated pinch roll 14 is tightly adhered by the clamping of the two pinch rolls 14, making it easy for the two heated pinch rolls 14 to seal the top of the packaging bag 6.

[0030] As shown in Fig. 1 and Fig. 2, two helical racks 16 are symmetrically provided on both sides of the outer side of the limiting bracket 5, and the two helical racks 16 correspond to the two chutes 13, respectively, and the teeth of the helical racks 16 face downward. A gear 17 is fixed to the surface of the protruding rod 15, and the pinch roll slides with the chutes 13 on one side of the two limiting brackets 5 through the gears 17 on the surfaces of the two protruding rods 15, and the inner surface of the gear 17 corresponds to and is attached to the outer surface of the limiting bracket 5, and the protruding rod 15 meshes with the teeth of the helical rack 16 through the gear 17. When the pinch roll 14 moves downward inside the chute 13 through the protruding rod 15, the protruding rod 15 moves the gear 17 downward at the same time, and the gear 17 meshes with the teeth of the helical rack 16, so that the gear 17 rotates during the downward movement. The gear 17 rotates the pinch rolls 14 simultaneously through the protruding rod 15, so that the two pinch rolls 14 rotate toward each other on both sides of the packaging bag 6, i.e., the left pinch roll 14 rotates counterclockwise and the right pinch roll 14 rotates clockwise, without pushing out both sides of the top of the packaging bag 6 during the rotation of the two pinch rolls 14 rotating toward each other. At this time, the diameter of the opening of the packaging bag 6 can be gradually reduced as the two pinch rolls 14 approach each other, so that the two pinch rolls 14 approaching each other can smoothly clamp the top opening of the packaging bag 6, and the top opening of the packaging bag 6 can always be facing upward during the contact of the two pinch rolls 14 rotating toward each other with the packaging bag 6.

[0031] 1 and 2, the surface of the protruding rod 15 is rotatably fitted on the bottom end of the rotary frame 18, the rotary frame 18 is located inside the limiting bracket 5, the bottom end of the rotary frame 18 is between the pinch roll 14 and the limiting bracket 5, the top ends of two adjacent rotary frames 18 are rotatably fitted on the surface of a screw 19, a nut 20 is screwed onto the inner end of the screw 19, the top side of the packaging bag is between the outer surface of the nut 20 and the top end of the rotary frame 18, and the top side of the packaging bag is restricted by the screwing of the nut 20 and the screw 19. Two fixing bars 29 are fixed to the inner surface of the limiting bracket 5, the outer end of the screw 19 is between the two fixing bars 29, and the two fixing bars 29 restrict the sliding direction of the screw 19. When the top side of the packaging bag 6 needs to be fixed, the nut 20 is loosened, the top side of the packaging bag 6 is placed between the nut 20 and the top end of the rotating frame 18, and the nut 20 is tightened, and the two nuts 20 on both sides and the spiral effect of the screw 19 make it easy to regulate the top side of the packaging bag 6, and to widen the top opening of the packaging bag 6. When the pinch roll 14 moves downward inside the chute 13 through the protruding rod 15, it gradually approaches and is close to each other while moving downward, so that the pinch roll 14 makes the bottom ends of the two rotating frames 18 approach each other while moving downward through the two protruding rods 15 at both ends, and the two fixing bars 29 regulate the inner ends of the screws 19, so that at this time, the top ends of the two rotating frames 18 rotate on the surface of the screws 19 to prevent the screws 19 from shifting during the rotation of the rotating frame 18. The screw 19 and the nut 20 work together to clamp the top opening of the packaging bag 6, and when the screw 19 moves upward between the two fixed bars 29 as the two rotating frames 18 move downward and rotate, the nuts 20 on both sides and the screw 19 pull the two top side edges of the packaging bag 6, so that the bag mouth of the packaging bag 6 gradually becomes smaller during the pulling process, making it easier for the two pinch rolls 14 to seal the bag mouth of the packaging bag 6.

[0032] As shown in Figures 1 and 2, the packaging structure further includes two bottom plates 21 arranged parallel to each other and facing each other, the bottom end of the packaging bag 6 is arranged corresponding to the top surfaces of the two bottom plates 21, protruding plates are provided on the outer parts of both ends of the two bottom plates 21, and a through groove 22 is provided in the center of the protruding plate, the two pinch rolls 14 are arranged corresponding to the two bottom plates 21, the top end of a movable plate 23 is rotatably fitted onto the surface of the protruding rod 15 at the end of the pinch roll 14, the center of the movable plate 23 passes through the through groove 22 on the surface of the protruding plate, a rotating wheel 24 is rotatably connected to the bottom end of the movable plate 23, the bottom end of the movable plate 23 rotatably fits with the top surface of the second slide rail 2 via the rotating wheel 24, and a screw 25 is screwed into the center of the end surface of the protruding plate, and the inner end of the screw 25 is in close contact with the outer surface of the movable plate 23. The protruding rods 15 at the ends of the two pinch rolls 14 are placed on the top of the chute 13, and the two bottom plates 21 are ensured to be in a horizontal state. When the packaging bag 6 is set, the bottom of the packaging bag 6 is placed corresponding to the tops of the two bottom plates 21, and the position of the bottom plate 21 on the surface of the movable plate 23 is adjusted according to the height of the packaging bag 6. The screw 25 is loosened, the bottom plate 21 is pushed and moved, and the nut 20 and the screw 19 cooperate to restrict the top side of the packaging bag 6. Then, the screw 25 is tightened, and the bottom plate 21 moves on the surface of the movable plate 23 through the through groove 22 on the surface of the protruding plate at the end until the bottom plate 21 is restricted on the movable plate 23. After the position of the bottom plate 21 is fixed, the rotating wheel 24 rotatably connected to the bottom of the movable plate 23 is placed on the second slide rail 2, and the packaging structure can roll on the top surface of the second slide rail 2 through the rotating wheel 24 at the bottom of the movable plate 23.

[0033] As shown in Figures 1 and 2, a sliding frame 26 is provided on the outside of the two limiting brackets 5, and both ends of the sliding frame 26 are movably fitted onto the surfaces of the two protruding rods 15. A sliding groove that slides onto the protruding rod 15 is provided on the inside of the top of the sliding frame 26. A sliding rod 27 is provided between the first slide rail 1 and the second slide rail 2. The sliding rod 27 is connected and fixed to a plurality of supports 3. A mounting rod 28 corresponding to the sliding rod 27 is provided on the outer surface of the sliding frame 26. The sliding frame 26 is always in sliding contact with the top surface of the sliding rod 27 via the mounting rod 28. When the packaging structure moves on the first slide rail 1 and the second slide rail 2 via the rollers 7 and the rotating wheel 24, the protruding rod 15 at the end of the pinch roll 14 moves the sliding frame 26 at the same time, and the sliding frame 26 slides on the top surface of the sliding rod 27 via the mounting rod 28. Since the weight of the items and packaging structure packed in the packaging bag 6 is applied to the sliding frame 26 through the protruding rod 15, the sliding frame 26 presses the sliding rod 27 via the mounting rod 28, and the weight of the items and packaging structure packed in the packaging bag 6 can keep the mounting rod 28 in contact with the sliding rod 27 at all times.

[0034] The sliding rod 27 includes a horizontal portion, an arc portion, a descending portion and an ascending portion.

[0035] When the sliding frame 26 slides on the horizontal portion of the sliding rod 27 via the supporting rod 28, the entire packaging structure and the packaging bag 6 can move smoothly along the circulation line, making it easy to insert articles into the packaging bag 6 through the opening at the top of the packaging bag 6.

[0036] When the sliding frame 26 slides on the arc portion of the sliding rod 27 via the mounting rod 28, the mounting rod 28 of the sliding frame 26 descends once on the arc portion and then moves upward, and when the sliding frame 26 moves downward, the pinch roll 14 is moved downward inside the chute 13 via the protruding rod 15, and the two pinch rolls 14 gradually approach the packaging bag 6 as they move downward. At this time, the two pinch rolls 14 make it easy to temporarily clamp the bag mouth of the packaging bag 6, reduce the diameter of the bag mouth of the packaging bag 6, and prevent the articles inside the packaging bag 6 from spilling out from the bag mouth. When the protruding rod 15 moves downward, it moves the top end of the movable plate 23 downward, at this time, the bottom end of the movable plate 23 rolls on the second slide rail 2 via the rotating wheel 24, the distance between the bottom ends of the two movable plates 23 becomes larger, and the two movable plates 23 rotate the two bottom plates 21 during the rotation process, at this time, the inner ends of the two bottom plates 21 gradually rotate downward, and the bottom end of the packaging bag 6 gradually moves downward with the rotation of the bottom plate 21, at this time, the top side edge of the packaging bag 6 is pulled by the spiral effect of the nut 20 and the screw 19, so that the diameter of the top bag mouth of the packaging bag 6 can be further reduced. When the sliding frame 26 moves upward, the sliding rod 27 pushes the sliding frame 26 upward via the mounting rod 28, the inner end of the movable plate 23 gradually moves upward, and the movable plate 23 rotates to return the two bottom plates 21 to a horizontal state.

[0037] When the sliding frame 26 slides on the descending part of the sliding rod 27 via the loading rod 28, refer to the sliding process of the circular arc part. At this time, the protruding rod 15 always moves downward inside the chute 13, and rotates the bottom plate 21 via the movable plate 23, thereby moving the packaging bag 6 downward, and the nut 20 and the screw 19 clamp the top of the packaging bag 6 to reduce the diameter of the packaging bag 6, making it easy for the two pinch rolls 14 to seal the bag mouth of the packaging bag 6 while rotating. When the two bottom plates 21 can no longer support the packaging bag 6, if the weight of the goods inside the packaging bag 6 exceeds the clamping force of the top side edge of the packaging bag 6 by the nut 20 and the screw 19, the packaging bag 6 filled with the goods will fall between the two bottom plates 21, thereby achieving the effect of transporting and packaging the goods.

[0038] When the sliding frame 26 slides on the ascending part of the sliding rod 27 through the supporting rod 28, referring to the sliding process of the arc part, the protruding rod 15 always moves upward inside the chute 13, and rotates the bottom plate 21 through the movable plate 23, which gradually becomes horizontal during rotation, and after the protruding rod 15 moves to the top of the chute 13, at this time, the supporting rod 28 of the sliding frame 26 gradually moves to the horizontal part of the sliding rod 27, and the above-mentioned process is repeated, making it easy to circulate and continuously pack articles using the packaging bags 6.

[0039] Principle of Operation of the Invention 1 to 3, the first slide rail 1 and the second slide rail 2 are installed according to the distance of the article to be transported, forming a circulation line for transporting and packaging. When the article needs to be transported and packaged, the bottom of the packaging bag 6 is placed corresponding to the top of the two bottom plates 21, the position of the bottom plate 21 on the surface of the movable plate 23 is adjusted according to the height of the packaging bag 6, the screw 25 is loosened, the bottom plate 21 is pushed and moved, and the top side edge of the packaging bag 6 is restricted by the cooperation of the nut 20 and the screw 19, and then the screw 25 is tightened, so that the bottom plate 21 moves on the surface of the movable plate 23 through the through groove 22 on the surface of the protruding plate at the end until the bottom plate 21 is restricted on the movable plate 23.

[0040] The packaging structure is pushed and moved, and the packaging structure moves on the first slide rail 1 and the second slide rail 2 via the rollers 7 and the rotating wheel 24. After being transported to the desired location, the bottom of the packaging structure is opened, and the packaging bag 6 filled with the article can be dropped from the bottom of the packaging structure, and the entire packaging structure continues to move, and a new packaging bag 6 is conveniently attached to the packaging structure.
