Description

Technical Field

[0001] This application relates to the field of automated equipment, and more particularly to a conveying capping and sealing machine. Background Technology

[0002] With the improvement of people's living standards, the demand for detergents is constantly increasing. Laundry detergent pods, as a new type of detergent, are widely welcomed by the market due to their convenient use and environmental protection features. The packaging box used for laundry detergent pods mainly includes a box body and a lid. The outer edge of the opening of the box body is provided with a ring-shaped edge, and the bottom edge of the lid body is provided with a groove for pressing with the ring-shaped edge. In the packaging process on the production line, the traditional method of manually pressing the lid is used to achieve the pressing between the box body and the lid body, but the overall efficiency is low. In order to improve efficiency, a lid pressing machine is used to complete the pressing step of the box body and the lid body.

[0003] In related technologies, a capping machine includes a base and a hydraulic cylinder located above the base and vertically downward. Packaging workers place the box on the base, then place the cap on the box. By activating the hydraulic cylinder, the piston rod of the hydraulic cylinder extends downward and presses down on the cap, thereby completing the pressing step of the cap and the box.

[0004] The aforementioned technologies have the following drawbacks: In actual operation, the one-time pressing method of the hydraulic cylinder can easily cause deformation or even breakage of the outer ring edge of the cover, resulting in a reduction in the packaging quality of the packaging box. Therefore, there is still room for improvement. Summary of the Invention

[0005] In order to improve the packaging quality of packaging boxes, this application provides a conveying capping and sealing machine.

[0006] The technical solution of the capping and sealing machine provided in this application is as follows:

[0007] A capping and pressing machine includes a frame, a lower conveyor belt mechanism, an upper conveyor belt mechanism, and a capping mechanism mounted on the frame. The lower conveyor belt mechanism conveys a box to be pressed, and a cap to be pressed is placed on the box. The upper conveyor belt mechanism is located above the lower conveyor belt mechanism, and a capping channel is formed between the upper and lower conveyor belt mechanisms. The conveying direction of the upper surface of the lower conveyor belt mechanism is the same as that of the lower surface of the upper conveyor belt mechanism, and the conveying speeds are equal. When the box and cap to be pressed enter the capping channel, the lower surface of the upper conveyor belt mechanism abuts against the upper surface of the cap, and the upper conveyor belt mechanism initially presses the cap onto the box. The box and cap, after initial pressing, move forward under the combined conveying action of the upper and lower conveyor belt mechanisms. When the box and cap, after initial pressing, move out of the capping channel and to the position of the capping mechanism, the capping mechanism presses the cap downward.

[0008] By adopting the above technical solution, this conveyor capping machine can effectively improve the pressing efficiency and quality of the box and lid. First, the coordinated work of the lower and upper conveyor belt mechanisms ensures that when the box and lid to be pressed enter the capping channel, the lower surface of the upper conveyor belt mechanism can evenly press against the upper surface of the lid, thus achieving initial pressing. This process not only improves the uniformity and stability of pressing but also avoids the problems of lid deformation or breakage that may occur with traditional one-time pressing. Second, the box and lid that have completed the initial pressing are continued to be conveyed to the capping mechanism, where the capping mechanism will finally press the lid downward to ensure a firm press between the lid and the box. The entire process achieves automated continuous operation, significantly improving production efficiency and packaging quality.

[0009] Preferably, the upper conveyor belt mechanism includes a mounting frame, a driven roller rotatably connected to the mounting frame, a driving roller rotatably connected to the mounting frame, a driving component for driving the driving roller to rotate, a plurality of pressure rollers disposed on the frame, and a synchronous belt sleeved between the driving roller, the driven roller, and the plurality of pressure rollers, wherein the height of the pressure rollers is lower than that of the driven roller and the driving roller.

[0010] By adopting the above technical solution, the design of the pressure roller of the upper conveyor belt mechanism being lower than that of the driven roller and the driving roller can ensure that the lower part of the front end of the synchronous belt is inclined downward. During the operation of the box and the cover, the synchronous belt enters the cover pressing channel smoothly. Under the downward pressure of the pressure roller, the synchronous belt maintains stable contact with the cover, which improves the quality and smoothness of the initial pressing of the cover and the box.

[0011] Preferably, the mounting frame includes a frame body, a mounting plate disposed on the frame body, and a connecting assembly disposed below the mounting plate. The pressure roller is rotatably connected to the connecting assembly. A height adjustment mechanism is provided between the connecting assembly and the mounting plate, and the height adjustment mechanism is used to adjust the height of the pressure roller.

[0012] By adopting the above technical solution, the height adjustment mechanism adjusts the height of the pressure roller. This design allows for flexible adjustment of the pressure roller's height, accommodating combinations of boxes and lids of varying thicknesses. This ensures uniformity and stability during the pressing process, avoids packaging quality issues caused by excessive or insufficient pressing force, and improves production efficiency and product quality.

[0013] Preferably, the height adjustment mechanism comprises a plurality of vertically downward-arranged adjustment cylinders, and the connecting assembly is installed at the telescopic end of the adjustment cylinders.

[0014] By adopting the above technical solution, the height of the pressure roller can be precisely adjusted to ensure that the pressure between the pressure roller and the upper surface of the cover is moderate, avoiding deformation or cracking of the outer ring edge of the cover due to excessive pressure, while ensuring the quality and stability of the initial pressing.

[0015] Preferably, the mounting bracket further includes a sliding shaft slidably connected to the underside of the mounting plate, the distance between the sliding shaft and the drive roller is adjustable, a locking fastener is provided between the sliding shaft and the mounting plate, and the driven roller is rotatably sleeved on the outer periphery of the sliding shaft.

[0016] By adopting the above technical solution, the distance between the sliding shaft and the driving roller is adjustable and fixed by fasteners, allowing the position of the driven roller to be adjusted according to actual needs. This design can adapt to boxes and covers of different sizes, improving the versatility and flexibility of the equipment, ensuring the stability and reliability of the pressing process. At the same time, the adjusted position of the driven roller can better match the tension of the synchronous belt, avoiding instability or damage caused by improper tension.

[0017] Preferably, the pressing mechanism includes a support frame, a lifting component vertically slidably connected to the support frame, and a pressing cylinder disposed on the top of the support frame. When the box and cover that have completed the initial pressing move to the support frame, the lifting component lifts the box away from the lower conveyor belt mechanism, and the pressing cylinder extends downward and presses the cover.

[0018] By adopting the above technical solution, when the box and lid, which have completed the initial pressing, move to the support frame, the lifting component first lifts the box away from the lower conveyor belt mechanism, so that the box is in a suspended state. Then, the pressure cylinder extends downward and precisely presses the lid, ensuring a firm pressing between the lid and the box, while protecting the lid from damage, thus improving the overall quality and production efficiency of the packaging box.

[0019] Preferably, the lifting components are distributed on both sides of the support frame. The lifting components include a support base disposed on the side of the support frame, a lifting cylinder disposed vertically on the support base, and a lifting arm slidably connected vertically to the support frame. The lifting arms on both sides of the support frame extend to the upper surface of the lower conveyor belt mechanism. When the box and cover, which have completed the initial pressing, move to the support frame, the lifting arms are located on both sides of the box and at the bottom of the annular outer edge of the box. The lifting cylinder extends and drives the lifting arms to move upward. The two lifting arms lift the box away from the lower conveyor belt mechanism by supporting the bottom of the annular outer edge of the box.

[0020] By adopting the above technical solution, the lifting arms are located on both sides of the box and at the bottom of the outer ring edge, ensuring that the lifting arms can smoothly lift the box under the action of the lifting cylinder. This makes the force between the lifting components and the two sides of the box more uniform, reduces the situation of excessive local force, and improves the overall quality and stability of the packaging box.

[0021] Preferably, the lower conveyor belt mechanism has parallel guide rods on both sides, and the length direction of the guide rods is consistent with the conveying direction of the lower conveyor belt mechanism. When the box is placed on the upper surface of the lower conveyor belt mechanism, the two guide rods abut against the two sides of the box respectively.

[0022] By adopting the above technical solution, the guide rod ensures the stability and accuracy of the box on the lower conveyor belt mechanism, preventing the box from shifting or tilting during transportation, thereby improving the alignment accuracy of the box and lid and the quality of the final pressing. At the same time, the guide rod design also makes the entire transportation process smoother, reducing production stoppages caused by improper box positioning and improving overall work efficiency.

[0023] In summary, this application includes at least one of the following beneficial technical effects:

[0024] 1. Through the coordinated action of the upper and lower conveyor belt mechanisms, the initial pressing of the cover is achieved, avoiding the problem of deformation or cracking of the outer edge of the cover caused by the one-time pressing operation of the traditional hydraulic cylinder, thus improving the quality of the packaging box;

[0025] 2. The lid-opening mechanism applies a second pressure to the box and lid that have already undergone initial pressing, further ensuring a tight fit between the lid and the box, and improving the final product's pass rate and reliability;

[0026] 3. The conveying direction and speed of the upper and lower conveyor belt mechanisms are consistent, which makes the entire pressing process smooth and orderly, improving the working efficiency and automation of the equipment. Attached Figure Description

[0031] The following is in conjunction with the appendix Figure 1-3 This application will be described in further detail.

[0032] This application discloses a conveying capping and sealing machine, referring to... Figure 1 and Figure 2 The system includes a frame 1, a lower conveyor belt mechanism 2, an upper conveyor belt mechanism 3, and a capping mechanism 4 mounted on the frame 1. The lower conveyor belt mechanism 2 conveys the boxes 6 to be pressed, with the caps 7 placed on the boxes 6. The frame 1 is divided into a capping area and a capping area along the conveying direction of the lower conveyor belt mechanism 2. The upper conveyor belt mechanism is located in the capping area and is mounted above the lower conveyor belt mechanism 2. The gap between the upper conveyor belt mechanism 3 and the lower conveyor belt mechanism 2 forms a capping channel 5. The capping mechanism 4 is located in the capping area and behind the discharge end of the capping channel 5. In this embodiment, the conveying direction of the upper surface of the lower conveyor belt mechanism 2 is the same as that of the lower surface of the upper conveyor belt mechanism 3, and the conveying speeds are equal. When the box 6 and the cover 7 to be pressed enter the pressing channel 5, the lower surface of the upper conveyor belt mechanism 3 presses against the upper surface of the cover 7, and the upper conveyor belt mechanism 3 initially presses the cover 7 onto the box 6. The box 6 and the cover 7, which have completed the initial pressing, move forward under the joint conveying action of the upper conveyor belt mechanism 3 and the lower conveyor belt mechanism 2.

[0033] After the box body 6 and the lid body 7, which have completed the initial pressing, move out of the pressing channel 5, they enter the lid opening area. When the box body 6 and the lid body 7, which have completed the initial pressing, move to the position of the lid opening mechanism 4, the lid opening mechanism 4 presses the lid body 7 downward.

[0034] Throughout the process, the coordinated operation of the lower conveyor belt mechanism 2 and the upper conveyor belt mechanism 3 ensures that when the box body 6 and the lid body 7 to be pressed enter the capping channel 5, the lower surface of the upper conveyor belt mechanism 3 can evenly press against the upper surface of the lid body 7, thereby achieving the initial pressing effect. This process not only improves the uniformity and stability of the pressing but also avoids the deformation or cracking of the lid body 7 that may be caused by traditional one-time pressing. Secondly, the box body 6 and the lid body 7 that have completed the initial pressing are continued to be conveyed to the position of the capping mechanism 4. At this time, the capping mechanism 4 will perform a final downward press on the lid body 7 to ensure that the lid body 7 and the box body 6 are firmly pressed together. The whole process realizes automated continuous operation, which significantly improves production efficiency and packaging quality.

[0035] It should be emphasized that the lower conveyor belt mechanism 2 is common in the material conveying field, while the upper conveyor belt mechanism 3 is specifically designed to improve the capping quality. Specifically, the upper conveyor belt mechanism 3 includes a mounting frame 31 mounted on the outside of the frame 1, a driven roller 33 rotatably connected to the mounting frame 31, a driving roller 34 rotatably connected to the mounting frame 31, a drive component 37 for driving the driving roller 34, several pressure rollers 35 disposed on the frame 1, and a synchronous belt 36 sleeved between the driving roller 34, the driven roller 33, and the pressure rollers 35. The synchronous belt 36 meshes with the driving roller 34 and the driven roller 33 for transmission. The drive component 37 is specifically a motor mounted on the mounting plate 313, with the motor's conveyor shaft coaxially and fixedly connected to the driving roller 34. The height of the pressure rollers 35 is lower than that of the driven roller 33 and the driving roller 34. Ensure that the lower front end of the synchronous belt 36 is inclined toward the inside of the capping channel 5, thereby expanding the feed end of the capping channel 5. During the operation of the box body 6 and the cover body 7, the synchronous belt 36 enters the capping channel 5 smoothly. Under the downward pressure of the pressure roller 35, the synchronous belt 36 maintains stable contact with the cover body 7, which improves the quality and smoothness of the initial pressing of the cover body 7 and the box body 6.

[0036] In this embodiment, the mounting frame 31 includes a frame body 314, a mounting plate 313 horizontally fixed on the frame body 314, and a connecting assembly 312 located below the mounting plate 313. The connecting assembly 312 is a U-shaped component, and the pressure roller 35 is rotatably connected between the bent portions at both ends of the connecting assembly 312. A height adjustment mechanism 32 is installed between the connecting assembly 312 and the mounting plate 313. The height adjustment mechanism 32 is used to adjust the height of the pressure roller 35. Specifically, the height adjustment mechanism 32 consists of several vertically downward-arranged adjusting cylinders, and the upper surface of the connecting assembly 312 is fixed to the telescopic ends of the adjusting cylinders. This allows for precise adjustment of the height of the pressure roller 35, ensuring moderate pressure between the pressure roller 35 and the upper surface of the cover 7. Excessive pressure prevents deformation or cracking of the outer ring edge of the cover 7, while also guaranteeing the quality and stability of the initial pressing. The height of the pressure roller 35 is adjusted via the height adjustment mechanism 32, allowing for flexible adjustment to accommodate combinations of box bodies 6 and cover bodies 7 of varying thicknesses. This ensures uniformity and stability during the pressing process, preventing packaging quality issues caused by excessive or insufficient pressing force, and improving production efficiency and product quality.

[0037] In this embodiment, the mounting frame 31 also includes a sliding shaft 311 slidably connected to the underside of the mounting plate 313. Specifically, a slot 3131 is provided on both sides of the bent section of the mounting plate 313. The two ends of the sliding shaft 311 are slidably connected to the slots 3131 on both sides of the mounting plate 313. In addition, the driven roller 33 is rotatably sleeved on the outer periphery of the sliding shaft 311, so that the distance between the driving roller 34 and the driven roller 33 at the sliding shaft 311 can be adjusted, which can adapt to different sizes of box 6 and cover 7, improve the versatility and flexibility of the equipment, and ensure the stability and reliability of the pressing process. At the same time, the adjusted position of the driven roller 33 can better match the tension of the synchronous belt 36, avoiding unstable conveying or damage caused by improper tension. In addition, a locking device is provided between the sliding shaft 311 and the mounting plate 313. The locking device is a conventional locking device consisting of a bolt and a nut. The bolt passes through the mounting plate 313 and the end of the sliding shaft 311 and is locked at the mounting plate 313. The end of the sliding shaft 311 is limited by two nuts, which helps to improve the stability of the sliding shaft 311.

[0038] Reference Figure 1 and Figure 3In this embodiment, the pressing mechanism includes a support frame 41 fixed to the outside of the frame 1, a lifting assembly 43 vertically slidably connected to the support frame 41, and a pressing cylinder 42 disposed on the top of the support frame 41. A horizontal pressure plate is fixed to the telescopic end of the pressing cylinder 42, and a vertically arranged guide rod with telescopic function is connected between the horizontal pressure plate and the support frame 41. When the box body 6 and the lid 7, after initial pressing, move to the support frame 41, the lifting assembly 43 lifts the box body 6 away from the lower conveyor belt mechanism 2, and the pressing cylinder 42 extends downwards and presses the lid 7 through the horizontal pressure plate. In the pressing step, the lifting assembly 43 first lifts the box body 6 away from the lower conveyor belt mechanism 2, so that the box body 6 is in a suspended state, and then the pressing cylinder 42 extends downwards to precisely press the lid 7, ensuring a firm press between the lid 7 and the box body 6, while protecting the lid 7 from damage, thus improving the overall quality and production efficiency of the packaging box.

[0039] In this embodiment, the pressing components are placed on both sides of the support frame 41. The pressing components include a support base 431 installed on the side of the support frame 41, a lifting cylinder 432 vertically mounted on the support base 431, and a lifting arm 433 vertically slidably connected to the support frame 41. The telescopic end of the lifting cylinder 432 is fixedly connected to the bottom of the lifting arm 433. The lifting arms 433 on both sides of the support frame 41 extend to the upper surface of the lower conveyor belt mechanism 2. When the box 6 and the cover 7, which have completed the initial pressing, move together to the support frame 41, the lifting arms 433 are located on both sides of the box 6 and at the bottom of the annular outer edge of the box 6. The lifting cylinder 432 extends and drives the lifting arms 433 to move upward. The two lifting arms 433 lift the box 6 away from the lower conveyor belt mechanism 2 by supporting the bottom of the annular outer edge of the box 6. Since the lifting arms 433 are located on both sides of the box body 6 and at the bottom of the outer edge of the ring, it ensures that the lifting arms 433 can smoothly lift the box body 6 under the action of the lifting cylinder 432, thereby making the force between the lifting component 43 and the two sides of the box body 6 more uniform, reducing the situation of excessive local force, and improving the overall quality and stability of the packaging box.

[0040] The implementation principle of a capping and pressing machine according to an embodiment of this application is as follows: the box body 6 and the lid body 7 to be pressed are placed on the lower conveyor belt mechanism 2 and moved to the lower conveyor belt mechanism 3 under the conveying action of the lower conveyor belt mechanism 2. The coordinated work of the lower conveyor belt mechanism 2 and the upper conveyor belt mechanism 3 enables the box body 6 and the lid body 7 to be pressed to enter the capping channel 5, and the lower surface of the upper conveyor belt mechanism 3 can be evenly pressed against the upper surface of the lid body 7, thereby achieving the initial pressing effect. This process not only improves the uniformity and stability of pressing, but also avoids the problem of deformation or cracking of the lid body 7 that may be caused by traditional one-time pressing.

[0041] Secondly, the box body 6 and lid 7, which have completed the initial pressing, will continue to be conveyed to the lid-opening mechanism 4. When the box body 6 and lid 7, which have completed the initial pressing, move together to the support frame 41, the lifting arms 433 are located on both sides of the box body 6 and at the bottom of the outer ring of the box body 6. The lifting cylinder 432 extends and drives the lifting arms 433 to move upward. The two lifting arms 433 lift the box body 6 away from the lower conveyor belt mechanism 2 by supporting the bottom of the outer ring of the box body 6. Then, the pressing cylinder 42 extends downward to precisely press the lid 7, ensuring a firm pressing between the lid 7 and the box body 6, while protecting the lid 7 from damage, thus improving the overall quality and production efficiency of the packaging box.

[0042] The preferred embodiments of the application are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made to the structure, shape, and principle of this application should be included within the scope of protection of this application.
