Description

Technical Field

[0001] The invention belongs to the field of packaging equipment, in particular to a carton packaging machine. Background Art

[0002] E-commerce is developing faster and faster, and the development of e-commerce has made great progress, so the demand for express delivery and packaging is increasing. Most of the packaging needs to be packed in cartons and then sealed. At present, because manual packaging is time-consuming and labor-intensive, large quantities of goods are no longer packed manually. Instead, packaging machines are used to seal cartons to improve work efficiency. Although packaging machines can automatically use tape to seal cartons, there are many problems with current packaging machines during the packaging process. For example, the two ends of the tape are not bonded firmly enough during the packaging process, and the top of the tape is not tightly enough. Some packaging machines still have the problem of incomplete cutting during the tape cutting process. As the use time increases, the cutting knife gradually becomes blunt, which causes problems in the cutting work and affects the actual cutting effect.

[0003] For example, patent CN202222952653.2 is a current mainstream packaging mechanism. This mechanism uses a carton to push a roller to drive the tape to adhere. However, the opening of the carton is elastic and will deform to a certain extent under external pressure, which makes it impossible for the tape to fit tightly with the carton. The tape at the end of the package will also have insufficient pressure because the carton and the roller move in the same direction, resulting in loose fitting. The cutting of the tape will also fail due to the bluntness of the cutting knife. These common packaging mechanisms all have similar problems. They usually rely on continuous adjustment to fit a fixed-size carton packaging, and they need to be frequently inspected and maintained to overcome problems such as blunt cutting knives and aging rollers. It is very inconvenient to use in actual work, and it also increases the cost of maintenance. Therefore, there is a need for a packaging machine that can overcome the above problems. Summary of the Invention

[0004] The present invention provides a carton sealing machine with improved tape sealing performance and increased maintenance intervals, and is particularly suitable for tape sealing of cartons. The technical problem to be solved is that the cutting blades of current sealing machines are easily blunted, and the tape and carton are not tightly bonded during the sealing process.

[0005] The technical solution adopted by the present invention is:

[0006] A carton packaging machine includes a frame, a conveyor belt, a mounting plate, a moving mechanism and a bonding mechanism. The frame is provided with a positioning plate above the conveyor belt, a guide rod is provided above the positioning plate, the frame is fixedly connected to the placement rack and the moving mechanism, the moving mechanism is slidably connected to the bonding mechanism, the mounting plate is connected to the driving belt through a hydraulic rod, and a guide plate is provided at the end of the driving belt.

[0007] Furthermore, mounting plates and driving belts are symmetrically arranged on both sides of the conveyor belt, belts are arranged on opposite sides of the two driving belts, and the guide plates at the ends of the driving belts are bent toward both sides of the conveyor belt.

[0008] Furthermore, the moving mechanism includes an outer slide, an inner slide, a fixed block, a moving block, a limit block and a reset mechanism. The inner slide is arranged inside the outer slide. The inner slide and the outer slide are inclined upward. The inner slide is slidably connected to the fixed block, the moving block and the limit block. The fixed block and the limit block are fixedly connected to the inner slide by screws. The moving block is arranged between the fixed block and the limit block. The moving block is connected to the fixed block through a reset mechanism.

[0009] Furthermore, the moving block is fixedly connected to the mounting frame, and the mounting frame is provided with bonding mechanisms on both sides of the moving mechanism.

[0010] Furthermore, a gap is left between the inner slide and the outer slide, a nut is set in the gap between the inner slide and the outer slide, and there is a gap in the bottom center of the inner slide, and the screws of the fixing block and the limiting block pass through the gap and then connect with the nut.

[0011] Furthermore, a positioning plate is provided at the end of the placement rack, two positioning plates are provided, threaded holes are provided on the side walls of the positioning plates, and the threaded holes of the positioning plates are connected to locking nails.

[0012] Furthermore, a guide wheel is provided at the end of the positioning plate where the bonding mechanism is located.

[0013] Furthermore, the bonding mechanism includes a mounting block, a cutting rod, a compacting rod and an elastic reset member. The mounting block is fixedly connected to the mounting frame above, a groove is provided below the mounting block, two gears meshing with each other are provided in the groove, the side walls of the two gears are fixedly connected to the compacting rod, the two compacting rods are connected by an elastic reset member, and a roller is provided between the two opposite compacting rods.

[0014] Furthermore, a limiting boss is provided at the center of the bottom of the groove of the mounting block, a cutting knife is provided at the bottom of the cutting rod, and a heating wire is provided on the cutting knife.

[0015] Furthermore, the guide rod is composed of a horizontal rod at one end and a rod inclined upward at the other end.

[0016] The above structure has the following beneficial effects:

[0017] 1. Since a moving mechanism is used to control the up and down movement and horizontal movement of the bonding mechanism, the touch height of the bonding mechanism can be adjusted, which overcomes the problem that the existing equipment cannot conveniently adjust the carton size adapted by the packaging equipment, so that it can quickly adapt to cartons of different sizes and facilitate the packaging work of cartons of different specifications.

[0018] 2. The two compacting rods of the bonding mechanism are used to cooperate to tighten the tape ends at both ends of the carton, which overcomes the problem that the existing equipment cannot ensure the bonding strength of the tail tape during the packaging process, thereby making the tape bonding more stable and strong, ensuring the bonding strength.

[0019] 3. Due to the use of positioning plates and guide rods, the carton lid can be closed automatically, overcoming the problem that the existing equipment needs to be closed manually and the bonding strength of the package is reduced due to the elasticity of the carton. The positioning plate provides support for the carton lid, so that the compacting rod has rigid support during the compaction process, thereby improving the bonding strength.

[0020] 4. The use of a hydraulic rod to connect the drive belt overcomes the problem that the operating structure of the existing equipment cannot be flexibly adjusted and cannot quickly adapt to different carton packaging tasks. The hydraulic rod is used to quickly adjust the distance between the two drive belts, which can better adapt to the packaging work of cartons of different specifications.

[0033] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0034] like Figure 1-10 As shown:

[0035] A carton packaging machine includes a frame 1, a conveyor belt 2, a mounting plate 3, a moving mechanism 4 and a bonding mechanism 5. The frame 1 is located above the conveyor belt 2 and a positioning plate 8 is provided. The positioning plate 8 provides support for the lid of the carton, avoiding the problem of reduced bonding strength due to the elasticity of the carton in traditional packaging work. A guide rod 7 is provided above the positioning plate 8. The guide rod 7 can automatically close the lid conveniently. The frame 1 is connected to the placement rack 6 and the moving mechanism 4 by screws. The moving mechanism 4 is slidably connected to the bonding mechanism 5 by a moving block. The mounting plate 3 is connected to the driving belt 11 by a hydraulic rod 9. A guide plate 10 is provided at the end of the driving belt 11. The guide plate 10 allows the carton to be automatically guided, thereby reducing the positioning accuracy of the feed.

[0036] The mounting plates 3 and driving belts 11 are symmetrically arranged on both sides of the conveyor belt 2. Belts 22 are arranged on opposite sides of the two driving belts 11. The belts use friction to push the cartons forward. The guide plates 10 at the ends of the driving belts 11 are bent toward the outside of the two sides of the conveyor belt 2.

[0037] The moving mechanism 4 includes an outer slide 12, an inner slide 13, a fixed block 14, a moving block 15, a limit block and a reset mechanism 17. The inner slide 13 is arranged inside the outer slide 12. The outer slide 12 and the inner slide 13 are fixed by screws. The inner slide 13 and the outer slide 12 are inclined upward structures. The inner slide is slidably connected to the fixed block 14, the moving block 15 and the limit block 16. The fixed block 14 and the limit block 16 are fixedly connected to the inner slide 13 by screws. The fixed block 14 and the limit block 16 provide a limiting function at both ends. The moving block 15 is arranged between the fixed block 14 and the limit block 16. During the movement of the bonding mechanism 5, the moving block 15 moves accordingly and gradually rises to the top of the carton. The moving block 15 is connected to the fixed block 14 through the reset mechanism 17. The reset mechanism 17 adopts a spring or an elastic telescopic rod. The elastic force resets the moving block 15 and provides pressure for the bonding mechanism 5 to improve the bonding strength.

[0038] The moving block 15 is welded with a mounting frame 18, and the mounting frame 18 is located on both sides of the moving mechanism 4 and is provided with bonding mechanisms 5. The roller 21 and the cutting knife 27 can be conveniently fixed by the bonding structures 5 on both sides.

[0039] A gap is left between the inner and outer slideways 13, 12, and a nut is positioned within the gap. A slit is formed at the bottom center of the inner slideway 13, through which the screws of the fixing block 14 and the stopper 16 pass and are then connected to the nut. The fixing block 14 and the stopper 16 can be secured and released by simply tightening the screws and nuts, making the tightening process more convenient and quick.

[0040] A positioning plate 19 is provided at the end of the placement frame 6. Two positioning plates 19 are provided. Threaded holes are provided on the side walls of the positioning plates 19. The threaded holes of the positioning plates 19 are connected to locking pins 20. The locking pins 20 fix the positioning plates 19 through friction. The two positioning plates 19 are located at both ends of the tape to position the tape.

[0041] The end portion where the positioning plate 8 is located at the bonding mechanism 5 is provided with a guide wheel 23. The guide wheel 23 is convenient for guiding the adhesive tape to avoid excessive friction of the adhesive tape during the guiding process.

[0042] The bonding mechanism 5 includes a mounting block 24, a cutting rod 25, a compacting rod 28, and an elastic reset member 29. A mounting frame 18 is welded above the mounting block 24. A groove is provided below the mounting block 24. Two gears 30 are meshed with each other in the groove. Compacting rods 28 are welded to the side walls of the two gears 30. The two compacting rods 28 are connected by an elastic reset member 29. A roller 21 is provided between the two opposing compacting rods 28. When the carton presses against the roller, the gears will cause the two compacting rods 28 to approach each other and move from the side wall of the carton to the top of the carton as the moving block 15 moves to compact and bond the tape. When the carton moves away from the roller 21, the compacting rod 28 is reset by the elastic reset member 29, and the other roller will press against the carton to compact the tail end of the tape. The elastic reset member 29 uses two connecting rods connected by shrapnel or springs. The ends of the two connecting rods connected by the springs are hinged, and the rotating shaft at the hinge is plugged into the cutting rod 25. When the elastic reset member 29 uses a spring, the middle portion of the spring is connected to the cutting rod 25 via a connecting rod. In addition to controlling the return of the two compacting rods 28, the elastic reset member 29 also ensures that the bottom of the cutting blade 27 is higher than the bottom of the roller 21 when the two compacting rods 28 are closed. The cutting rod 25 is slidably connected to the mounting block 24 via a sliding groove.

[0043] A limiting boss 26 is provided at the center position of the bottom of the groove of the mounting block 24. The limiting boss 26 prevents the compacting rod 28 from excessive movement and plays a limiting role. A cutting knife 27 is provided at the bottom of the cutting rod 25. A heating wire is provided on the cutting knife 27. With the assistance of the heating wire, high temperature can be used for cutting, making the cutting work more convenient and avoiding the problem of the cutting knife becoming blunt over time. High-temperature cutting can make up for the problem of the cutting knife becoming blunt.

[0044] The guide rod 7 is composed of a horizontal rod at one end and a rod inclined upward at the other end.

[0045] How this example works:

[0046] During use, after placing the carton sample, start the hydraulic rod 9 to clamp the sample to ensure that the belt can stably drive the sample to run, adjust the height of the positioning plate to adapt to the carton, adjust the height of the bonding mechanism 5 to adjust the length of the end tape, and place the tape on the placement rack 6 after adjustment, and use the positioning plate 19 to position and clamp it, then pull out the end of the tape and pass it through the guide wheel 23 and wrap it around the roller 21 at the right end, place the box on the conveyor belt 2, and after being guided and positioned by the guide plate 10, it is positioned and transported by the belt. The upper box cover is guided by the guide rod 7 and pressed above the positioning plate 8, and the box body is located under the positioning plate 8. As the box body moves, it hits the roller 21 on the right. At this time, the two compacting rods 28 are pressed against the roller 21 on the right due to the original gear. Because of the opposite rotation and driving the cutting knife to move upward, the roller 21 is pressed on the top of the box cover, supported by the positioning plate 8, and under the pressure of the reset mechanism 17, the roller 21 presses the bonding part, avoiding the problem of low bonding strength due to the elasticity of the carton, greatly improving the bonding strength. As the carton leaves the position of the bonding mechanism 5, the bonding mechanism 5 moves downward with the help of the reset mechanism 17, and the compacting rod opens quickly under the action of the reset elastic reset member 29. When opened, the roller 21 on the left is close to the back of the carton and the cutting rod 25 moves downward and drives the cutting knife 27 to cut the tape. In order to prevent the cutting knife 27 from aging, an electric heating wire is added to use high temperature to quickly melt the tape, reducing the difficulty of cutting while increasing the life of the cutting knife 27.

[0047] This method effectively improves the adhesive strength of the tape packaging and allows pressure sealing at both ends of the tape, overcoming the problem of existing equipment that only provides light adhesion at the end of the tape, resulting in low adhesive strength. Furthermore, a heating wire is added to the blade, allowing for auxiliary cutting with the aid of a fuse in addition to blade cutting, effectively reducing the cutting difficulty and blade wear, extending the life of the cutter 27, and extending maintenance intervals to reduce maintenance costs.

[0048] In Example 2, if packaging is required on both the upper and lower sides, the conveyor belt 2 only needs to be replaced with two separate conveyor belts 2 on the left and right. The moving mechanism 4, bonding mechanism 5 and placement rack 6 are symmetrically arranged at the gap between the two conveyor belts 2 and above.

[0049] In order to prevent the box from tilting upward during the packaging process, downward sloping stripes are set on the belt 22. Since the force is always perpendicular to the contact surface, the box is not completely flat. When some points contact the inclined stripes, they will be subjected to a downward sloping force, thereby strengthening the fit between the box and the conveyor belt 2, preventing the box from moving upward when packaging from below, and improving the packaging effect of the upper and lower surfaces.

[0050] In Example 3, when packaging the upper and lower surfaces, two packaging machines can be set up continuously, and a carton turning mechanism can be set in the middle of the two packaging machines.

The present invention is not limited to the above embodiments, and its specific structure is allowed to be varied. All variations made within the scope of protection of the independent claims of the present invention are within the scope of protection of the present invention.
