Description

Technical Field

[0001] This utility model relates to the technical field of folding and sealing equipment, specifically a carton folding and sealing equipment with a pre-pressure guiding mechanism. Background Technology

[0002] Carton folding and sealing equipment is a type of packaging machinery that integrates automated forming, precise folding, and efficient sealing. It is mainly used to automatically form the carton body and fold the edges of flat corrugated cardboard or cardboard blanks through mechanical actions, and seal the carton opening / edges with tape or hot melt adhesive. Its core value lies in replacing manual operation and solving the efficiency bottleneck and quality stability problems in batch packaging scenarios. It is widely used in industries that require large-scale carton packaging, such as e-commerce logistics, food and daily chemicals, and home appliances and electronics.

[0003] In existing technologies, the positioning mechanisms of existing equipment mostly use metal baffles of fixed size, which can only be adapted to a single size of carton. However, when it is necessary to switch to cartons of different widths, not only is it necessary to manually disassemble the baffles and re-drill holes for installation, which is cumbersome and takes more than 15 minutes, seriously reducing the efficiency of folding and sealing, but more importantly, the manually adjusted baffles are prone to gap deviations between themselves and the cartons, causing the cardboard to shift laterally during transportation. This results in the edges of the folded cartons not being straight, and the tape or glue cannot evenly cover the seams during sealing. Ultimately, this affects the sealing quality and further restricts the improvement of production efficiency. Utility Model Content

[0004] The purpose of this invention is to provide a carton folding and sealing device with a pre-pressure guiding mechanism, in order to solve the problems mentioned in the background art. The positioning mechanism of the existing equipment is mostly a fixed-size metal baffle, which is only suitable for a single specification of carton. When switching to cartons of different widths and lengths, the baffle needs to be manually disassembled and re-drilled and installed. Moreover, after adjustment, gap deviation is easily generated, which leads to the offset of the cardboard conveying, which reduces the folding and sealing efficiency and affects the sealing quality.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a carton folding and sealing device with a pre-pressure guiding mechanism, including a conveying device, a folding and sealing device body installed on the conveying device, a controller fixedly connected to the folding and sealing device body, a support frame fixedly connected to one side of the folding and sealing device body, a connecting frame slidably connected to the support frame, a first drive assembly installed on the support frame, a positioning plate fixedly connected to one end of the connecting frame, a pressing assembly installed on the positioning plate, and a second drive assembly installed on the pressing assembly. The first drive assembly is used to drive the connecting frames on both sides to move synchronously closer or further apart, and the pressing assembly is used to press the two sides of the carton.

[0006] In the preferred embodiment of this technical solution, two sets of connecting frames and positioning plates are provided. The two sets of connecting frames and positioning plates are symmetrically distributed on the support frame, and the support frame has through slots at corresponding positions of the two sets of connecting frames. The two sets of connecting frames are slidably connected to the through slots of the support frame.

The connecting ear is fixedly connected to the telescopic end of the hydraulic telescopic rod. The rack meshes with the circular gear. The other end of the connecting frame is fixedly connected to the rack. The hydraulic telescopic rod is electrically connected to a controller. The hydraulic telescopic rod is used to drive the rack on one side to slide on the support frame, and then, by meshing with the circular gear, it drives the rack on the other side to slide synchronously in the opposite direction.

[0008] In the preferred embodiment of this technical solution, the support frame has a groove at the corresponding position of the rack, and the rack is slidably connected to the groove of the support frame.

[0009] According to the preferred embodiment of this technical solution, the pressing component includes an adjusting plate slidably connected to the positioning plate, a smooth rod slidably connected to the adjusting plate, a stop plate fixedly connected to one end of the smooth rod, a spring fixedly connected between the adjusting plate and the stop plate, a limiting disc fixedly connected to the other end of the smooth rod, and a rotating roller rotatably connected to the stop plate. The second driving component is used to drive the adjusting plate to move vertically in a straight line.

[0010] In the preferred embodiment of this technical solution, the positioning plate has a limiting groove at the corresponding position of the adjusting plate, and the adjusting plate is slidably connected to the limiting groove of the positioning plate.

[0011] Based on the preferred embodiment of this technical solution, several sets of rotating rollers are provided, and these sets of rotating rollers are sequentially distributed on the support plate.

[0012] In a preferred embodiment of this technical solution, the second drive assembly includes a support plate fixedly connected to the positioning plate, a self-locking threaded rod rotatably connected to the support plate, a second bevel gear fixedly connected to one end of the self-locking threaded rod, an optical shaft rotatably connected to the positioning plate, a knob fixedly connected to one end of the optical shaft, and a first bevel gear fixedly connected to the other end of the optical shaft. An adjustment plate is threadedly connected to the self-locking threaded rod, the first bevel gear meshes with the second bevel gear, and the knob is used to rotate the optical shaft.

[0013] Compared with the prior art, the beneficial effects of this utility model are: 1. By synchronously driving the connecting frames and positioning plates on both sides through the first drive component, the carton on the conveying device can be precisely centered and limited, effectively avoiding lateral deviation during the conveying process. At the same time, this structure can flexibly adapt to cartons of different widths without the need for frequent manual adjustments, significantly improving the equipment's adaptability to positioning of cartons of various specifications, reducing problems such as folding misalignment and uneven sealing caused by positioning deviations, and ultimately improving the operating efficiency and sealing quality of the folding and sealing equipment itself.

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] Please see Figure 1-5This utility model provides an embodiment of a carton folding and sealing device with a pre-pressure guiding mechanism, including a conveying device 1, a folding and sealing device body 4 mounted on the conveying device 1, a controller 5 fixedly connected to the folding and sealing device body 4, a support frame 21 fixedly connected to one side of the folding and sealing device body 4, a connecting frame 26 slidably connected to the support frame 21, a first driving component mounted on the support frame 21, a positioning plate 27 fixedly connected to one end of the connecting frame 26, a pressing component mounted on the positioning plate 27, and a second driving component mounted on the pressing component. The first driving component is used to drive the connecting frames 26 on both sides to move synchronously closer or further away. The pressing component is used to press the two sides of the carton. The controller 5 can coordinate the actions of each component. The first driving component and the pressing component cooperate to achieve accurate positioning and stable pressing of the carton, providing a reliable foundation for subsequent folding and sealing, and reducing the matching error caused by structural dispersion.

[0019] Please see Figure 2 A further solution based on this embodiment is as follows: two sets of connecting frames 26 and positioning plates 27 are provided. The two sets of connecting frames 26 and positioning plates 27 are symmetrically distributed on the support frame 21, and the support frame 21 has through slots at corresponding positions of the two sets of connecting frames 26. The two sets of connecting frames 26 are slidably connected to the through slots of the support frame 21. Through the symmetrical distribution of the two sets of connecting frames 26 and positioning plates 27, symmetrical constraints can be formed from both sides of the carton to ensure the centering effect during positioning. The through slots provide guidance for the sliding of the connecting frames 26 to avoid offset or jamming when the connecting frames 26 move, ensuring that the positioning plates 27 on both sides move synchronously and improving the symmetry and stability of the carton positioning.

[0020] Please see Figure 2 A further solution based on this embodiment is as follows: The first driving assembly includes a circular gear 23 rotatably connected to the support frame 21, a rack 24 slidably connected to the support frame 21, a hydraulic telescopic rod 22 fixedly connected to the support frame 21, and a connecting ear 25 fixedly connected to one side of the rack 24. The connecting ear 25 is fixedly connected to the telescopic end of the hydraulic telescopic rod 22. The rack 24 meshes with the circular gear 23. The other end of the connecting frame 26 is fixedly connected to the rack 24. The hydraulic telescopic rod 22 is electrically connected to the controller 5. The hydraulic telescopic rod 22 is used to drive the rack 24 on one side... The support frame 21 slides, and then engages with the circular gear 23 to drive the rack 24 on the other side to slide synchronously in the opposite direction. The hydraulic telescopic rod 22 drives the rack 24 on one side to slide. With the engagement of the circular gear 23 and the racks 24 on both sides, the racks 24 on both sides move synchronously in opposite directions, thereby driving the connecting frame 26 and the positioning plate 27 to move closer or further away synchronously, ensuring the accuracy and synchronization of the positioning adjustment. The hydraulic drive power is stable and controlled by the controller 5, requiring no manual operation. It is convenient to adjust when adapting to cartons of different widths, improving the adaptability and efficiency of the equipment.

[0021] Please see Figure 2 A further solution based on this embodiment is as follows: the support frame 21 has a groove at the corresponding position of the rack 24, and the rack 24 is slidably connected to the groove of the support frame 21. The groove limits and guides the sliding of the rack 24, which can constrain the movement trajectory of the rack 24, prevent the rack 24 from shifting laterally or tilting during the sliding process, ensure that the rack 24 and the circular gear 23 are always stably meshed, reduce transmission error, and improve the operating stability and adjustment accuracy of the first drive component.

[0022] Please see Figure 2 A further embodiment of this solution is as follows: The pressing assembly includes an adjusting plate 31 slidably connected to the positioning plate 27, a smooth rod 32 slidably connected to the adjusting plate 31, a stop plate 33 fixedly connected to one end of the smooth rod 32, a spring 312 fixedly connected between the adjusting plate 31 and the stop plate 33, a limiting plate 35 fixedly connected to the other end of the smooth rod 32, and a rotating roller 34 rotatably connected to the stop plate 33. The second driving assembly is used to drive the adjusting plate 31 to move vertically. Through the elastic action of the spring 312, the stop plate 33 and the rotating roller 34 can elastically press the two sides of the carton, ensuring stable pressing force and avoiding excessive pressure that could damage the cardboard. The rotating roller 34 can rotate with the carton conveyor, reducing friction during pressing and preventing obstruction of the carton conveyor. The smooth rod 32 and the limiting plate 35 cooperate to limit the displacement of the stop plate 33, ensuring the structural stability of the pressing assembly and improving the reliability of pressing the carton.

[0023] Please see Figure 2 A further solution based on this embodiment is as follows: the positioning plate 27 has a limiting groove at the corresponding position of the adjusting plate 31, and the adjusting plate 31 is slidably connected to the limiting groove of the positioning plate 27. The limiting groove guides the sliding of the adjusting plate 31, which can ensure that the adjusting plate 31 moves up and down in a straight line under the drive of the second driving component, avoid the adjustment plate 31 from shifting and causing the pressing component to deviate, ensure the alignment accuracy of the rotating roller 34 with the two sides of the carton, and improve the working stability of the pressing component.

[0024] Please see Figure 5 A further solution based on this embodiment is as follows: the rotating roller 34 is provided with several sets, and the several sets of rotating rollers 34 are sequentially distributed on the back plate 33. By having several sets of rotating rollers 34 sequentially distributed on the back plate 33, the contact area with the side of the carton can be increased, making the pressing pressure distribution more uniform and avoiding excessive local pressure that could cause deformation of the side of the carton. At the same time, the coordinated action of multiple sets of rotating rollers 34 can better adapt to the slight unevenness of the side of the carton, improving the stability and fit of the pressing.

[0025] Please see Figure 4A further solution based on this embodiment is as follows: The second drive assembly includes a support plate 39 fixedly connected to the positioning plate 27, a self-locking threaded rod 310 rotatably connected to the support plate 39, a second bevel gear 311 fixedly connected to one end of the self-locking threaded rod 310, an optical shaft 36 rotatably connected to the positioning plate 27, a knob 37 fixedly connected to one end of the optical shaft 36, and a first bevel gear 38 fixedly connected to the other end of the optical shaft 36. An adjusting plate 31 is threadedly connected to the self-locking threaded rod 310, and the first bevel gear 38 is connected to the second bevel gear 310. Two bevel gears 311 mesh, and knob 37 is used to rotate optical shaft 36. Rotating optical shaft 36 via knob 37 drives self-locking threaded rod 310 to rotate via first bevel gear 38 and second bevel gear 311, causing adjustment plate 31 to move up and down along threaded rod, thereby realizing height adjustment of pressing component, which is convenient to operate; self-locking threaded rod 310 has a self-locking function, which can stably maintain the position of adjustment plate 31 after adjustment, avoiding height deviation caused by vibration during operation, ensuring the matching accuracy of pressing component and carton, and improving the adjustment reliability of equipment.

[0026] Working principle: First, the conveyor device 1 transports the carton blank, and the controller 5 coordinates the start-up of each component. To adapt to the width of the carton, the controller 5 controls the extension and retraction of the hydraulic telescopic rod 22. Through the connecting lug 25, it drives one side rack 24 to slide along the slide groove of the support frame 21. The rack 24 meshes with the circular gear 23, driving the other side rack 24 to slide synchronously in the opposite direction. This, in turn, drives the two connecting frames 26 on both sides to move closer or further away from each other along the through groove of the support frame 21, so that the two sets of positioning plates 27 form a centering limit from both sides of the carton, achieving precise positioning. Subsequently, according to the height of the carton, the knob 37 is turned to drive the optical shaft 36 to rotate, and the other side of the optical shaft 36... The first bevel gear 38 at the end meshes with the second bevel gear 311 on the self-locking threaded rod 310, driving the self-locking threaded rod 310 to rotate. This causes the adjusting plate 31 to slide up and down along the limiting groove of the positioning plate 27 until the rotating roller 34 is at the same height as the side of the carton, and the self-locking threaded rod 310 locks itself in this position. At this point, the pressing assembly begins to work: the smooth rod 32 on the adjusting plate 31 drives the abutment plate 33 to press against the sides of the carton with the rotating roller 34. The elastic force of the spring 312 makes the rotating roller 34 press the carton stably. At the same time, the rotating roller 34 rotates with the carton during transport to reduce friction. Several sets of rotating rollers 34 ensure that the pressing pressure is evenly distributed. Finally, the carton, after being positioned and stably pressed, is transported to the folding and sealing equipment body 4 to complete the folding and sealing process. The entire process is continuous and efficient, ensuring stable sealing quality.
