Description

Technical Field

[0001] This utility model relates to the field of packaging box sealing technology, and in particular to a highly adaptable automatic packaging box sealing machine. Background Technology

[0002] Nowadays, more and more packaging boxes are using easy-open lids for sealing. Compared with traditional lids, easy-open lids open in one step, reducing operation steps and physical exertion. Users can open canned goods, beverages and other packaging directly by hand, eliminating the need for can openers or knives, which is especially suitable for fast-paced lifestyles.

[0003] Easy-open lids come in many forms, such as drawer-style sliding lids, magnetic closures, pull rings, or tear strips. One type uses an interference fit to secure the lid inside the packaging box, creating a seal through radial pressure between the lid and the container opening, generating friction that prevents air and moisture penetration. This method eliminates the need for magnets, glue, or other external materials, and avoids additional processing such as grooving or marking. It is cost-effective, simple to seal, and pollution-free, making it ideal for packaging food, medicine, and other similar items.

[0004] When sealing these types of packaging boxes, the box body and lid are typically secured and sent to a sealing mechanism, which then inserts the lid into the box. In standard operation, these two steps usually require two separate drive mechanisms, increasing costs and necessitating close coordination between them to prevent interference.

[0005] In addition, many food packaging boxes are currently customized in style and size by customers. However, it is difficult for a single sealing machine to adapt to packaging boxes of different sizes and styles. Configuring a sealing machine for each type of packaging box would put a lot of cost pressure on manufacturers. Utility Model Content

[0006] In view of this, the purpose of this utility model is to propose a highly adaptable automatic sealing machine for packaging boxes, so as to solve the technical problems of increased cost and low compatibility caused by multiple drive mechanisms in the existing sealing machine.

[0007] To achieve the above objectives, this utility model provides a highly adaptable automatic sealing machine for packaging boxes, including a positioning component for fixing the packaging box and a machine frame, wherein the positioning component is slidably connected to the frame, and further includes:

[0008] The pressure plate and the rotating wheel are located above the positioning component. The pressure plate is fixedly connected to the frame, and the rotating wheel is rotatably connected to the frame.

[0009] A motor is fixedly installed within a frame, and the wheel is connected to the motor's output shaft via a transmission assembly;

[0010] The lifting mechanism includes a motor connected to the lifting mechanism via a transmission assembly. The lifting mechanism is used to drive the positioning component to lift and lower so that the packaging box can cooperate with the mating pressure plate and the rotating wheel for sealing.

[0011] Furthermore, the lifting mechanism includes a cam and a lever. The motor drives the cam to rotate, and the cam presses against one end of the lever. The lever is rotatably connected within the frame, and the other end of the lever abuts against the lower end of the positioning member.

[0012] Furthermore, the lifting mechanism also includes a worm and a worm wheel. The worm is connected to the output shaft of the motor through a transmission assembly. The worm wheel meshes with the worm and is rotatably connected within the frame. The cam is fixedly connected to the worm wheel through a connecting rod.

[0013] Furthermore, the positioning component includes a lifting column and a fixed tray. The lifting column is slidably connected to the frame, and the bottom of the lifting column is located inside the frame and connected to the lifting mechanism. The fixed tray is connected to the top of the lifting column.

[0014] Furthermore, a stud is fixedly connected to the bottom of the fixed tray, and the stud is threaded into the lifting column.

[0015] Furthermore, the upper end of the fixed tray is provided with a placement groove, and the center of the placement groove is provided with a through hole for suction and fixing the packaging box.

[0016] Furthermore, the fixed tray is also provided with a negative pressure chamber, which is connected to the through hole, and the negative pressure chamber is also provided with a negative pressure generating mechanism, which is used to generate negative pressure in the negative pressure chamber after the through hole is blocked.

[0017] Furthermore, the negative pressure generating mechanism includes a piston plate slidably connected within the negative pressure chamber, a slide rod rotatably connected to the outer side of the piston plate, the slide rod slidably connected within a fixed tray, and a screw fixedly connected to the other end of the slide rod, the screw threadedly connected within the fixed tray, and the other end of the screw fixedly connected to a knob, the knob being movably connected to the fixed tray.

[0018] The beneficial effects of this utility model are as follows: 1. By setting a positioning component to fix the packaging box, the positioning component can be raised and lowered, and then the pressure plate and rotating wheel press the top cover into the packaging box to form a seal. The pressure plate has a certain buffer margin to avoid excessive pressure damaging the packaging box. The rotating wheel rotates circumferentially to squeeze the top cover, forming a seal on the edge of the cover. The rotation makes it easier to press the top cover into the packaging box to form an interference fit, and also allows the top cover to fit more tightly and seamlessly with the packaging box.

[0019] 2. The rotation of the rotating wheel and the lifting of the positioning component are both driven by a single motor, saving costs. The motor drives the cam to rotate in conjunction with the lever to lift the packaging box. When the cam protrusion contacts the lever, the lever lifts the positioning component. After the cam protrusion leaves the lever, the positioning component descends. This process coincides with the sealing cycle of the packaging box. Through the gear ratio, the rotating wheel is driven to rotate multiple times during this process, ensuring accurate coordination between the two action mechanisms.

[0020] 3. The positioning tray in the positioning component can be height-adjusted using studs, thus accommodating packaging boxes of various heights. A through-hole is formed in the placement slot at the top of the positioning tray; negative pressure is generated within this hole to hold the packaging box in place, ensuring that any packaging box with a flat bottom can be initially secured by the positioning component. The rotating wheels, connected by multiple rods, can also adjust the distance between the wheels and the center of the pressure plate, thereby accommodating packaging boxes of various diameters and greatly improving overall adaptability.

[0029] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to specific embodiments.

[0030] It should be noted that, unless otherwise defined, the technical or scientific terms used in this utility model should have the ordinary meaning understood by one of ordinary skill in the art to which this utility model pertains. The terms "first," "second," and similar terms used in this utility model do not indicate any order, quantity, or importance, but are merely used to distinguish different components. Terms such as "comprising" or "including" mean that the element or object preceding the word encompasses the elements or objects listed following the word and their equivalents, without excluding other elements or objects. Terms such as "connected" or "linked" are not limited to physical or mechanical connections, but can include electrical connections, whether direct or indirect. Terms such as "upper," "lower," "left," and "right" are used only to indicate relative positional relationships; when the absolute position of the described object changes, the relative positional relationship may also change accordingly.

[0031] The first aspect of this utility model is as follows: Figure 1 , Figure 2 and Figure 3 As shown, when using an interference fit to seal a packaging box, the box body and lid are typically fixed and sent to the sealing mechanism, which then inserts the lid into the box. In conventional operations, these two steps usually require two drive mechanisms, increasing costs and requiring a high degree of coordination between them to avoid interference. Therefore, this solution employs a combined drive approach. Specifically, a positioning component 10 for fixing the packaging box and a device frame 11 are provided, with the positioning component 10 and frame 11 slidably connected.

[0032] A pressure plate 12 and a rotating wheel 13 are arranged above the positioning component 10. The pressure plate 12 is fixedly connected to the frame 11, and the rotating wheel 13 is rotatably connected to the frame 11. A motor 14 is fixedly installed inside the frame 11, and the rotating wheel 13 is connected to the output shaft of the motor 14 through a transmission assembly 15.

[0033] An additional lifting mechanism is provided. The motor 14 is connected to the lifting mechanism through the transmission component 15. The lifting mechanism is used to drive the positioning component 10 to lift so that the packaging box can cooperate with the mating pressure plate 12 and the rotating wheel 13 to seal.

[0034] The lifting mechanism includes a cam 18 and a lever 19. The motor 14 drives the cam 18 to rotate, and the cam 18 presses against one end of the lever 19. The lever 19 is rotatably connected within the frame 11, and the other end of the lever 19 abuts against the lower end of the positioning member 10. The lifting mechanism also includes a worm gear 16 and a worm wheel 17. The worm gear 16 is connected to the output shaft of the motor 14 through a transmission assembly 15. The worm wheel 17 meshes with the worm gear 16 and is rotatably connected within the frame 11. The cam 18 is fixedly connected to the worm wheel 17 through a connecting rod.

[0035] The rotation of the rotating wheel 13 and the lifting of the positioning component 10 are both driven by a motor 14, saving costs. The motor 14 drives the cam 18 to rotate in conjunction with the lever 19 to lift the packaging box. When the protruding part of the cam 18 contacts the lever 19, the lever 19 lifts the positioning component 10. After the protruding part of the cam 18 leaves the lever 19, the positioning component 10 will descend. This process is exactly the operation cycle of sealing the packaging box. Through the gear ratio, the rotating wheel 13 is driven to rotate multiple times during this process, ensuring accurate coordination between the two action mechanisms.

[0036] The pressure plate 12 has a certain margin for buffering movement to prevent excessive pressure from damaging the packaging box. The rotating wheel 13 rotates circumferentially to press the top cover, forming a seal at the edge of the cover. The rotation makes it easier to press the top cover into the packaging box to form an interference fit, and also allows the top cover to fit more tightly and seamlessly with the packaging box.

[0037] The second aspect of this utility model addresses the issue that many food packaging boxes are currently customized in style and size by customers. A single sealing machine is unlikely to be suitable for all sizes and styles of packaging boxes, and requiring a separate sealing machine for each type of box would place a significant cost burden on manufacturers. Therefore, this embodiment incorporates a positioning component 10, which includes a lifting column 101 and a fixed tray 103. The lifting column 101 is slidably connected to the frame 11, with its bottom located within the frame 11 and connected to the lifting mechanism. The fixed tray 103 is connected to the top of the lifting column 101.

[0038] Preferably, a stud 102 is fixedly connected to the bottom of the fixed tray 103, and the stud 102 is threadedly connected to the lifting column 101.

[0039] The fixed tray 103 has a placement groove 104 at its upper end, and a through hole 105 at the center of the placement groove 104 for holding and fixing the packaging box. The fixed tray 103 also has a negative pressure chamber 106, which is connected to the through hole 105. The negative pressure chamber 106 is also equipped with a negative pressure generating mechanism to generate negative pressure in the negative pressure chamber 106 when the through hole 105 is blocked.

[0040] The negative pressure generating mechanism includes a piston plate 107 slidably connected within the negative pressure chamber 106. A slide rod 108 is rotatably connected to the outer side of the piston plate 107. The slide rod 108 is slidably connected within the fixed tray 103, and a screw 109 is fixedly connected to the other end of the slide rod 108. The screw 109 is threadedly connected within the fixed tray 103, and the other end of the screw 109 is fixedly connected to a knob 110. The knob 110 is movably connected to the fixed tray 103.

[0041] The positioning component 10's fixed tray 103 can be height-adjusted via studs 102, thus adapting to various packaging boxes of different heights. A through-hole 105 is formed in the placement groove 104 at the upper end of the fixed tray 103. By generating negative pressure in the through-hole 105, the packaging box is held in place; therefore, any packaging box with a flat bottom can be initially fixed by the positioning component 10. The rotating wheel 13, connected by multiple linkages, can also adjust the distance between the rotating wheel 13 and the center of the pressure plate 12, thereby adapting to packaging boxes of various diameters and greatly improving overall compatibility.

[0042] Therefore, when fixing the packaging box, simply place the packaging box in the center of the placement slot 104 and block the through hole 105. Then, by rotating the knob 110, the screw 109 and slide bar 108 are rotated and moved, driving the piston plate 107 to move. This increases the space in the negative pressure chamber 106 that is connected to the through hole 105, creating negative pressure and achieving initial adsorption and fixing of the packaging box.

[0043] In summary, this utility model uses a positioning element 10 to fix the packaging box. The positioning element 10 can move up and down, and the pressure plate 12 and the rotating wheel 13 press the top cover into the packaging box to form a seal. The pressure plate 12 has a certain buffer margin to prevent excessive pressure from damaging the packaging box. The rotating wheel 13 rotates circumferentially to press the top cover, forming a seal at the edge. The rotation makes it easier to press the top cover into the packaging box to form an interference fit, and it also allows the top cover to fit more tightly and seamlessly with the packaging box. Moreover, the rotation of the rotating wheel 13 and the raising and lowering of the positioning element 10 are both driven by a single motor 14, which saves costs. The motor 14 drives the cam 18 to rotate in conjunction with the lever 19 to lift and lower the packaging box. When the protrusion of the cam 18 contacts the lever 19, the lever 19 lifts the positioning part 10. After the protrusion of the cam 18 leaves the lever 19, the positioning part 10 will descend. This process is exactly the operation cycle of sealing the packaging box. Through the gear ratio, the rotating wheel 13 is driven to rotate multiple times during this process, ensuring the accurate coordination of the two action mechanisms.

[0044] Furthermore, the fixed tray 103 in the positioning component 10 can be height-adjusted via studs 102 to accommodate packaging boxes of various heights. A through-hole 105 is formed in the placement groove 104 at the upper end of the fixed tray 103. By generating negative pressure in the through-hole 105, the packaging box is held in place, thus allowing any packaging box with a flat bottom to be initially secured by the positioning component 10. The rotating wheel 13, connected by multiple rods, can also adjust the distance between the rotating wheel 13 and the center of the pressure plate 12, thereby accommodating packaging boxes of various diameters and greatly improving overall adaptability.
