Description

Technical Field

[0001] This utility model relates to the field of packaging equipment technology, and in particular to a fully automatic adaptive wet kraft paper sealing machine. Background Technology

[0002] Water-resistant kraft paper tape is made from kraft paper as the base material, coated with edible plant starch adhesive, and becomes sticky after being wetted. Current technology generally uses wet kraft paper as a sealing material, as it has good adhesion and toughness. The wet kraft paper tape adheres tightly to the carton, forming a strong seal, effectively preventing the carton from falling apart during transportation and storage. Furthermore, kraft paper is environmentally friendly and recyclable, aligning with environmental protection principles. Traditional manual sealing methods require tearing, cutting, and wetting the kraft paper tape, which is complex, inefficient, and makes it difficult to guarantee sealing quality. Currently, wet kraft paper sealing machines are available to improve the standardization of sealing. However, current sealing machines are usually customized according to the size of the carton, making it impossible to effectively and continuously seal cartons of different sizes. When changing to different sized cartons, manual mold changes and adjustments are required, severely impacting production efficiency and sealing accuracy. Utility Model Content

[0003] Based on this, the purpose of this utility model is to provide a fully automatic adaptive wet kraft paper sealing machine that can automatically adjust the sealing parameters according to different sizes of cartons without the need for manual mold replacement or complex adjustments. It can adapt to various specifications of packaging boxes, has strong adaptability, can meet the requirements of continuous production, improve production efficiency and reduce equipment costs.

[0016] The brake band passes around the tray assembly, with one end fixed to the fixing plate and the other end fixed to the brake rod at the end away from the paper winding roller. When the kraft paper tape is in a slack state, the elastic element pulls the movable end of the brake rod to deflect toward the tray assembly, and the brake rod drives the brake band to abut against the tray assembly to brake the tray assembly.

[0043] Currently, wet kraft paper sealing machines on the market are usually customized according to the size of the packaging box. When changing to packaging boxes of different sizes, it is necessary to manually change the mold and adjust the relative position of the feeding mechanism and the sealing mechanism to achieve effective transportation and sealing of packaging boxes of different sizes. This manual adjustment method is inefficient and requires calibration after adjustment, which seriously affects production efficiency and sealing accuracy.

[0044] Based on this, this application provides a fully automatic adaptive wet kraft paper sealing machine that can automatically adjust sealing parameters according to different sizes of cartons without the need for manual mold replacement or complex adjustments. It can adapt to various specifications of packaging boxes, has strong adaptability, can meet continuous production operations, improve production efficiency and reduce equipment costs.

[0045] Please see Figure 1-3 This application provides a fully automatic adaptive wet kraft paper sealing machine, including: a frame 10, a feeding mechanism 20, a first sealing mechanism 30 and a second sealing mechanism 70, and a first lifting mechanism 40. The feeding mechanism 20, the first sealing mechanism 30 and the second sealing mechanism 70, and the first lifting mechanism 40 are all mounted on the frame 10.

[0046] The frame 10 is equipped with a transport platform 11 for transporting packaging boxes. A feeding mechanism 20 is used to stably clamp and move the packaging boxes. This feeding mechanism 20 includes a conveying component 21 and an adjusting component 22. The conveying component 21 is slidably connected to the frame 10 and positioned above the transport platform 11, moving the packaging boxes on the platform. The fixed end of the adjusting component 22 is fixed to the frame 10, and its movable end is drivenly connected to the conveying component 21. The adjusting component 22 drives the conveying component 21 to move in a direction perpendicular to the direction of the packaging box's movement, adapting to the width of the packaging box.

[0047] The first sealing mechanism 30 and the second sealing mechanism 70 are respectively located above and below the transport platform 11 to seal the upper and lower sealing surfaces of the packaging box. The first lifting mechanism 40 drives the first sealing mechanism 30 to move vertically to adapt to the height of the packaging box. The fixed end of the first lifting mechanism 40 is fixed to the frame 10, and its movable end is driven to the first sealing mechanism 30, driving the first sealing mechanism 30 to move in the height direction of the frame 10.

[0048] The fully automatic adaptive wet kraft paper sealing machine provided in this application embodiment improves sealing efficiency by simultaneously sealing the packaging box from both the top and bottom sealing surfaces using a first sealing mechanism 30 and a second sealing mechanism 70. Furthermore, an adjustment component 22 adjusts the position of the conveying component 21 to adapt to the width of the packaging box. Additionally, a first lifting mechanism 40 is provided to adjust the height of the first sealing mechanism 30 to adapt to the height of the packaging box, enabling efficient transportation and sealing of packaging boxes of different sizes.

[0049] In this embodiment, the transport platform 11 is a roller assembly, which facilitates the movement of the packaging box on the transport platform 11 by the conveying assembly 21. A slit is opened in the middle of the transport platform 11, and a second sealing mechanism 70 is located below the transport platform 11 to seal the lower sealing surface of the packaging box from the slit.

[0050] Furthermore, in some embodiments, the frame 10 is also provided with a support frame 12, which includes a support crossbar 121 and support vertical bars 122 fixed to both ends of the support crossbar 121; one end of the support vertical bar 122 away from the support crossbar 121 is vertically fixed to the transport platform 11, and the first sealing mechanism 30 is slidably connected to the support vertical bar 122. The first lifting mechanism 40 is provided with a first motor 41 and two sets of first lead screws 42. The first lead screws 42 are rotatably connected to the support vertical bar 122 and are drive-connected to the first sealing mechanism 30 to drive the first sealing mechanism 30 to move along its length. The first motor 41 is fixed to the support crossbar 121, and its output end is drive-connected to the two sets of first lead screws 42 to drive the first sealing mechanism 30 to lift.

[0051] Specifically, the first sealing mechanism 30 is slidably connected to the support rod 122 by a slider 312. The slider 312 is also threadedly connected to the first lead screw 42. When the first lead screw 42 rotates, it causes the slider 312 and the first sealing mechanism 30 to slide up and down relative to the support rod 122, so as to adjust the sealing height of the first sealing mechanism 30 to adapt to the height of the packaging box.

[0052] As an example, the first motor 41 and the two sets of first lead screws 42 are connected by a synchronous belt to drive the two sets of first lead screws 42 to rotate synchronously. It is understood that in some other embodiments, other transmission methods may be used between the first motor 41 and the two sets of first lead screws 42 to achieve synchronous movement of the two sets of first lead screws 42, which will not be described in detail here.

[0053] Furthermore, in some embodiments, the conveying components 21 are in two sets, symmetrically arranged on both sides of the packaging box to clamp the packaging box. Each conveying component 21 has a conveyor belt that abuts against the two side walls of the packaging box in the width direction to clamp the packaging box and drive it to move along the conveyor belt's conveying direction. The conveying component 21 also has a limit switch 211 for controlling the clamping of the packaging box by the conveying component 21.

[0054] Furthermore, in some embodiments, the adjusting assembly 22 includes an adjusting motor 221 and an adjusting screw assembly 222. The adjusting motor 221 is fixed to the frame 10, and its output end is drivenly connected to one end of the adjusting screw assembly 222. The two ends of the adjusting screw assembly 222 have opposite thread directions and are drivenly connected to two sets of conveying assemblies 21 respectively. The adjusting motor 221 drives the adjusting screw assembly 222 to rotate, thereby causing the two sets of conveying assemblies 21 to move closer or further apart, adapting to the width of the packaging box. It is understood that the transmission connection between the adjusting motor 221 and the adjusting screw assembly 222 can be synchronous belt drive, gear meshing drive, or other transmission methods, and is not limited thereto.

[0055] Specifically, in this embodiment, the adjusting screw assembly 222 consists of two sets of screws coupled along the length direction, which are respectively connected to the two sets of conveying components 21 by threads, driving the two sets of conveying components 21 to move in opposite directions, thereby adjusting the distance between the two sets of conveying components 21 to adapt to the width of the packaging box.

[0056] Please see Figure 1 and Figure 4-6 Furthermore, in some embodiments, the first sealing mechanism 30 includes a first mounting frame 31, and an unwinding assembly 32, a paper feeding assembly 33, a paper cutting assembly 34, a wetting assembly 35, and a paper pressing assembly 36 arranged sequentially according to the direction of movement of the kraft paper strip. The first mounting frame 31 is slidably connected to the supporting vertical rod 122, and the unwinding assembly 32, the paper feeding assembly 33, the paper cutting assembly 34, the wetting assembly 35, and the paper pressing assembly 36 are all fixedly connected to the first mounting frame 31.

[0057] Furthermore, the unwinding assembly 32 includes a fixed plate 321 and a tray rotation structure 322. The fixed plate 321 is fixedly connected to the first mounting frame 31, and the tray rotation structure 322 is fixedly connected to the fixed plate 321 for placing the material strip 80. Specifically, the tray rotation structure 322 includes a fixed shaft 3221, a tray assembly 3222, and a bearing. The fixed shaft 3221 is vertically fixed to the fixed plate 321, and the tray assembly 3222 is rotatably connected to the fixed shaft 3221 through the bearing. The material strip 80 is mounted on the tray assembly 3222, and the discharge of the material strip 80 drives the tray assembly 3222 to rotate.

[0058] Furthermore, in some embodiments, the unwinding assembly 32 also includes an emergency braking structure 323, used to brake the rotating material tray structure 322 in case of a sudden stop in the material belt output, so as to avoid the unwinding assembly 32 from jamming due to the loosening of the material belt. The emergency braking structure 323 includes a brake rod 3231, an elastic element 3232, and a brake band 3233. One end of the brake rod 3231 is rotatably connected to the fixed plate 321, and the other end is provided with a paper winding roller 3234, and is connected to the fixed plate 321 through the elastic element 3232; when the material belt is in a tensioned state, the material belt abuts against the paper winding roller 3234, pulling the brake rod 3231 to deflect, so that its movable end is away from the material tray assembly 3222, at which time the elastic element 3232 undergoes tensile deformation.

[0059] Furthermore, the brake band 3233 passes around the tray assembly 3222, with one end fixed to the fixing plate 321 and the other end fixed to the end of the brake lever 3231 away from the paper winding roller 3234. When the belt slackens, it loses its traction on the paper winding roller 3234. The elastic force of the elastic element 3232 pulls the movable end of the brake lever 3231 to deflect toward the tray assembly 3222. The rotating end of the brake lever 3231 drives the brake band 3233 to abut against the tray assembly 3222, thereby braking the tray assembly 3222.

[0060] Furthermore, in some embodiments, the paper feeding assembly 33 is arranged adjacent to the unwinding assembly 32 for pulling out the kraft paper strip. Specifically, the paper feeding assembly 33 includes a traction motor 331, a traction wheel 332, and a rubber-coated shaft 333; the traction wheel 332 and the rubber-coated shaft 333 are respectively clamped on both ends of the kraft paper strip, the traction motor 331 is fixed to the first mounting frame 31, and its output end is drivenly connected to the traction wheel 332 to drive the traction wheel 332 to rotate, thereby pulling the kraft paper strip out from the feed tray assembly 3222.

[0061] Furthermore, the paper cutting assembly 34 is disposed between the paper feeding assembly 33 and the wetting assembly 35, and is used to cut kraft paper strips of a fixed length. Specifically, the cutting assembly 34 includes a cutter 341 and a cutting power component 342 for driving the cutter 341 to move. In this embodiment, the cutting power component 342 is a cylinder, which is fixedly connected to the first mounting frame 31, and its output end is fixedly connected to the cutter 341 to drive the cutter 341 to cut the kraft paper strip. It is understood that in other embodiments, the cutting power component 342 may also be other linear motion modules that drive the cutter 341 to reciprocate, which will not be described in detail here.

[0062] Furthermore, in some embodiments, the wet assembly 35 includes a water tank 351, a wet roller brush 352, and a roller brush motor 353. The water tank 351 is fixedly connected to the first mounting frame 31; the wet roller brush 352 is detachably rotatably disposed within the water tank 351, and the roller brush motor 353 is fixedly connected to the outer wall of the water tank 351, with its output end connected to the wet roller brush 352. During the operation of the first sealing mechanism 30, the roller brush motor 353 drives the wet roller brush 352 to rotate, which is used to brush water onto the adhesive surface of the kraft paper tape to make it sticky. Specifically, in this embodiment, the water tank 351 is fixedly connected to the first mounting frame 31 from both sides by handle screws 311. When cleaning or maintenance of the wet assembly 35 is required, the wet assembly 35 can be disassembled simply by removing the handle screws 311.

[0063] Specifically, in this embodiment, the roller brush motor 353 and the wet roller brush 352 are connected by a round pulley and a synchronous belt drive to drive the wet roller brush 352 to rotate synchronously. This transmission method facilitates the disassembly of the wet roller brush 352 and facilitates the subsequent cleaning of the water tank 351 and the wet roller brush 352.

[0064] Furthermore, the wet assembly 35 also includes a quick-release screw 355, through which the wet roller brush 352 is confined within the water tank 351. When it is necessary to clean the water tank 351 or the wet roller brush 352, the wet roller brush 352 can be removed from the water tank 351 simply by removing the quick-release screw 355.

[0065] Furthermore, the wet assembly 35 also includes a pressure plate 354 disposed opposite the wet roller brush 352, the pressure plate 354 being provided with an electric heating film for heating the kraft paper strip. Preferably, the electric heating film is attached to the side of the pressure plate 354 facing away from the wet roller brush 352.

[0066] Further, in some embodiments, the paper pressing assembly 36 includes a first swing arm 361, a second swing arm 362, a damping element 363, and a connecting rod 364 for connecting the first swing arm 361 and the second swing arm 362. Both the first swing arm 361 and the second swing arm 362 are rotatably connected to the first mounting frame 31, and each has a pressing roller 3611 at its end for pressing the kraft paper strip; the pressing roller 3611 rolls and presses the kraft paper strip on the packaging box to seal the box. One end of the damping element 363 is rotatably connected to the first mounting frame 31, and the other end is hinged to the first swing arm 361 or the second swing arm 362 to drive the first swing arm 361 and the second swing arm 362 to reset. As an example, in this embodiment, the damping element 363 is a cylinder. In other embodiments, the damping element 363 can also be a spring or other structure that can drive the paper pressing assembly 36 to reset, and is not limited thereto.

[0067] Furthermore, in some embodiments, the second sealing mechanism 70 has the same structure as the first sealing mechanism 30 and is used to seal the lower sealing surface of the packaging box.

[0068] Please see Figure 1 and Figure 3 Furthermore, the fully automatic adaptive wet kraft paper sealing machine provided in this application embodiment also includes a second lifting mechanism 50, used to fix one end of the second sealing mechanism 70 to the frame 10 and the other end to the second sealing mechanism 70. One end of the second sealing mechanism 70 is rotatably connected to the frame 10, and the other end can be deflected by the second lifting mechanism 50, so that the unwinding component of the second sealing mechanism 70 protrudes from the cut end from the transport platform 11, facilitating material changing. Specifically, the second lifting mechanism 50 can be a linear motion module such as a cylinder that drives the second sealing mechanism 70 to deflect, which will not be described in detail here.

[0069] Please see Figure 1 and Figure 6 Furthermore, the fully automatic adaptive wet kraft paper sealing machine provided in this application embodiment also includes a water supply mechanism 60 for supplying water to the water tank 351. The water supply mechanism 60 includes an inlet pump 61, an outlet pump 62, and a first water tank 63 fixed on the frame 10. The inlet end of the inlet pump 61 is connected to the first water tank 63, and its outlet end is detachably connected to the water tank 351 of the first sealing mechanism 30 and the second sealing mechanism 70. The inlet end of the outlet pump 62 is detachably connected to the water tank 351 of the first sealing mechanism 30 and the second sealing mechanism 70, and its outlet end is connected to the first water tank 63, forming a complete circulating water circuit.

[0070] Specifically, the outlet end of the inlet pump 61 is detachably connected to the water tank 351 via an inlet pipe 611, and the inlet end of the outlet pump 62 is detachably connected to the water tank 351 via an outlet pipe 621. Furthermore, both the inlet pipe 611 and the outlet pipe 621 are equipped with sensors 65 to detect whether the pipeline is short of water.

[0071] Furthermore, the water supply mechanism 60 also includes a second water tank 64, which is fixed to the frame 10 and connected to the inlet pump 61 for supplying water to the water tank 351. When the water tank 351 needs to be cleaned, the second water tank 64 is connected to the inlet pump 61, and the water in the second water tank 64 is pumped into the water tank 351. Then, the wastewater in the water tank 351 is pumped into the first water tank 63 via the outlet pump 62, forming a water tank cleaning flow path.

[0072] Compared with the prior art, the beneficial effects of the embodiments of this application are as follows:

[0073] (1) By setting the adjustment component and the first lifting mechanism, the sealing parameters can be automatically adjusted according to the different sizes of cartons. There is no need to manually change the mold or make complicated adjustments.

[0074] (2) By setting up a first sealing mechanism and a second sealing mechanism to seal the packaging box from the top and bottom sealing surfaces simultaneously, the sealing efficiency is improved;

[0075] (3) By setting a second lifting mechanism to drive the second sealing mechanism to deflect upward, the unwinding component of the second sealing mechanism protrudes from the transport platform, making it easier to change materials;
