Description

Technical Field

[0001] This utility model relates to the technical field of packaging sealing device, and more particularly to a packaging sealing device. Background Technology

[0002] Mineral water is uncontaminated underground mineral water that flows naturally from deep underground or is artificially exposed. It contains a certain amount of mineral salts, trace elements, or carbon dioxide gas. Bottled mineral water is often packaged in cardboard boxes. Cardboard packaging refers to the use of paper boxes to protect the product and facilitate storage and transportation during the distribution process.

[0003] Chinese patent publication number CN218807020U discloses a packaging box sealing device, including an operating table. A buffer mechanism is fixedly connected to the outside of the operating table. The buffer mechanism includes a base, a placement plate movably connected to the outside of the base, a support rod fixedly connected to the outside of the placement plate, and a first toothed plate fixedly connected to the outside of the support rod. A gear is meshed with the outside of the first toothed plate, and a second toothed plate is meshed with the outside of the gear. A connecting rod is fixedly connected to the outside of the second toothed plate. This invention utilizes the placement plate movably connected to the outside of the base. When urea falls into the packaging box, it compresses the placement plate, causing the support rod to move downwards. This moves the first toothed plate, which in turn meshes with the gear, which in turn meshes with the second toothed plate. This movement of the first toothed plate causes the connecting rod to compress a damping spring, achieving a buffering effect and facilitating the production and processing of automotive urea.

[0004] Existing packaging sealing devices have drawbacks such as requiring the four side flaps of the box opening to be folded during sealing, which can obstruct the folding of the front and rear flaps, and making it inconvenient to adjust the height of the holding components according to the height of the box. To overcome these disadvantages, this utility model provides a packaging sealing device. Utility Model Content

[0005] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a packaging and sealing device.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a packaging and sealing device, comprising a base, side frames symmetrically fixedly connected to both sides of the upper end of the base, a first sliding groove provided on the inner side of each side frame, a packaging box disposed at the center of the upper part of the base, a movable frame disposed above the packaging box, both ends of the movable frame being slidably connected to corresponding first sliding grooves, a second sliding groove provided on the bottom side of the top of the movable frame, a support frame symmetrically slidably connected to both ends of the second sliding groove, a pressure roller rotatably connected to the inner side of the bottom of each support frame, a bidirectional screw rotatably connected to the second sliding groove, a slide rail fixedly connected to the top of the movable frame, a slider slidably connected to one end of the slide rail, a first telescopic rod fixedly connected to the bottom of the slider, a fixing block fixedly connected to the bottom of the first telescopic rod, a first spring sleeved on the outer side of the first telescopic rod, second telescopic rods fixedly connected to both sides of the fixing block, a connecting rod fixedly connected to one end of each second telescopic rod, a lever fixedly connected to one end of each connecting rod, and a second spring sleeved on the outer side of each second telescopic rod.

[0007] Furthermore, a one-way screw is rotatably connected inside one side of the side frame, one end of which is threadedly connected to the movable frame. A first motor is fixedly connected to the top of one side of the side frame at the position corresponding to the one-way screw. The output end of the first motor passes through the top side wall of the corresponding side frame and is fixedly connected to one end of the one-way screw. A limit rod is fixedly connected inside one side of the side frame, and one end of the movable frame is slidably connected to the limit rod.

[0008] Furthermore, both ends of the bidirectional screw are threadedly connected to the corresponding support frame, and a second motor is fixedly connected to one side of the movable frame at the position corresponding to the bidirectional screw. The output end of the second motor passes through the side wall of the movable frame and is fixedly connected to one end of the bidirectional screw.

[0009] Furthermore, a slide rod is fixedly connected inside the slide rail, and the slider is slidably connected to the slide rod.

[0010] Furthermore, the two ends of the first spring are fixedly connected to the slider and the fixed block, respectively, and the two ends of the second spring are fixedly connected to the fixed block and the corresponding connecting rod, respectively.

[0012] The beneficial effects of this utility model are:

[0013] When in use, this packaging sealing device has the following advantages:

[0014] 1. In this solution, a side frame, a first slide rail, a one-way screw, a limit rod, a packaging box, a movable frame, a second slide rail, a two-way screw, a support frame, and pressure rollers are provided. The operation of the first motor drives the one-way screw to rotate, thereby moving the movable frame up and down along the first slide rail. This facilitates the raising and lowering of the support frames and pressure rollers on both sides according to the height of the packaging box, improving applicability and flexibility. The operation of the second motor drives the two-way screw to rotate, thereby moving the support frame towards each other along the second slide rail. The pressure rollers on the inner side of the bottom of the support frame assist in folding and pressing the flaps on the left and right sides inward, making it convenient to seal the box with tape.

[0015] 2. In this solution, a slide rail, slide bar, slider, first telescopic rod, fixing block, first spring, second telescopic rod, connecting rod, second spring, lever, hook, and hanging ring are provided. When the slider is pulled to the center of the carton, the fixing block is pulled down so that the lever is on the inside of the carton fold. At this time, the first telescopic rod and the first spring are stretched under force, and the hanging ring is removed from the hook. The second spring, which was initially in a compressed state, returns to its original state, causing the corresponding second telescopic rod to stretch. The connecting rods on both sides spring outward, and the levers on both sides push the folds on the left and right sides of the carton outward, making it easier to fold the folds on the front and back sides inward. This avoids the folds on the left and right sides from obstructing the folding of the front and back sides, reduces the squeezing and damage between adjacent folds during folding, and improves the ease of use.

[0023] like Figure 1-3 As shown, a packaging and sealing device is disclosed, comprising a base 1, side frames 2 symmetrically fixedly connected to the upper two sides of the base 1, each side frame 2 having a first sliding groove 3 on its inner side, a packaging box 7 disposed at the center of the upper part of the base 1, a movable frame 8 disposed above the packaging box 7, the two ends of the movable frame 8 being slidably connected to the corresponding first sliding groove 3, a second sliding groove 9 being disposed at the bottom side of the top of the movable frame 8, a support frame 11 symmetrically slidably connected to the two ends of the second sliding groove 9, a pressure roller 13 rotatably connected to the inner side of the bottom of the support frame 11, and a bidirectional screw 10 rotatably connected to the second sliding groove 9. The top end is fixedly connected to a slide rail 14, one end of which is slidably connected to a slider 16. The bottom end of the slider 16 is fixedly connected to a first telescopic rod 17, and the bottom end of the first telescopic rod 17 is fixedly connected to a fixing block 18. A first spring 19 is sleeved on the outside of the first telescopic rod 17. A second telescopic rod 20 is fixedly connected to both sides of the fixing block 18. A connecting rod 21 is fixedly connected to one end of each second telescopic rod 20. A lever 23 is fixedly connected to one end of each connecting rod 21. The lever 23 has an L-shaped telescopic structure for easy extension and retraction. A second spring 22 is sleeved on the outside of each second telescopic rod 20.

[0024] like Figure 1-3As shown, a one-way screw 4 is rotatably connected inside one side frame 2. One end of the one-way screw 4 is threadedly connected to the movable frame 8. A first motor 5 is fixedly connected to the top of one side frame 2 at the position corresponding to the one-way screw 4. The output end of the first motor 5 passes through the top side wall of the corresponding side frame 2 and is fixedly connected to one end of the one-way screw 4. A limit rod 6 is fixedly connected inside one side frame 2. One end of the movable frame 8 is slidably connected to the limit rod 6. Both ends of the bidirectional screw 10 are threadedly connected to the corresponding support frame 11. A second motor is fixedly connected to one side of the movable frame 8 at the position corresponding to the bidirectional screw 10. 12. The output end of the second motor 12 passes through the side wall of the movable frame 8 and is fixedly connected to one end of the bidirectional screw 10. The first motor 5 is started, thereby driving the unidirectional screw 4 to rotate, which in turn drives the movable frame 8 to move up and down along the first slide groove 3, so as to facilitate the raising and lowering of the support frames 11 and pressure rollers 13 on both sides according to the height of the packaging box 7. The second motor 12 is started, thereby driving the bidirectional screw 10 to rotate, which in turn drives the support frame 11 to move towards each other along the second slide groove 9. The pressure rollers 13 on the inner side of the bottom end of the support frame 11 are used to fold the flaps on the left and right sides inward, which is convenient for sealing the box with tape.

[0025] like Figure 1-3 As shown, a slide rod 15 is fixedly connected inside the slide rail 14, and a slider 16 is slidably connected to the slide rod 15. The two ends of the first spring 19 are fixedly connected to the slider 16 and the fixed block 18, respectively. The first spring 19 is initially in a natural state. The two ends of the second spring 22 are fixedly connected to the fixed block 18 and the corresponding connecting rod 21, respectively. A hook 24 is fixedly connected to one side of the fixed block 18. A hanging ring 25 is hinged to the end of the connecting rod 21 near the hook 24. The hanging ring 25 is engaged with the corresponding end of the hook 24. The second spring 22 is initially in a compressed state. Pulling the slider 16 to the center of the carton and pulling down the fixed block 18 makes the lever 23 position inside the carton fold. At this time, the first telescopic rod 17... The first spring 19 extends under force, simultaneously removing the hanging ring 25 from the hook 24. The initially compressed second spring 22 resets, causing the corresponding second telescopic rod 20 to extend. The connecting rods 21 on both sides spring outward, and the levers 23 on both sides push the folds on the left and right sides of the carton outward, making it easier to fold the folds on the front and back sides inward, avoiding the left and right folds from obstructing the folding of the front and back sides. After folding, the connecting rods 21 are pulled again to hang the hanging ring 25 on the hook 24. The fixing block 18 is released, and the first telescopic rod 17 and the first spring 19 reset and retract, causing the fixing block 18 to retract upward as a whole. The lever 23 is a telescopic structure. Retracting the lever 23 can push the slider 16 to one end of the slide rail 14.

[0026] Working principle: In use, the first motor 5 is started, which drives the one-way screw 4 to rotate, thereby driving the moving frame 8 to move up and down along the first slide groove 3. This facilitates the raising and lowering of the support frames 11 and pressure rollers 13 on both sides according to the height of the packaging box 7. At the same time, the slider 16 is pulled to the center of the carton, and the fixing block 18 is pulled down to place the lever 23 on the inside of the carton fold. At this time, the first telescopic rod 17 and the first spring 19 are stretched by force, and the hanging ring 25 is removed from the hook 24. The second spring 22, which was initially compressed, returns to its original position, causing the corresponding second telescopic rod 20 to extend. The connecting rods 21 on both sides spring outward, and the levers 23 on both sides push the folds on the left and right sides of the carton outward. Fold the front and rear flaps inward to prevent the left and right flaps from obstructing the folding of the front and rear flaps. After folding, pull the connecting rod 21 again and hang the hanging ring 25 on the hook 24. Release the fixing block 18, and the first telescopic rod 17 and the first spring 19 will return to their original positions and retract, causing the fixing block 18 to retract upward as a whole. The lever 23 is a telescopic structure. Retracting the lever 23 can push the slider 16 to one end of the slide rail 14. Then start the second motor 12, which will drive the bidirectional screw 10 to rotate, thereby driving the support frame 11 to move in opposite directions along the second slide groove 9. The pressure roller 13 on the inner side of the bottom of the support frame 11 will help fold the left and right flaps inward, making it convenient to seal the box with tape.
