Description

Technical Field

[0001] This utility model relates to the field of packaging box technology, specifically to an adjustable-size tape sealing machine. Background Technology

[0002] A tape sealing machine is a packaging device used to automate the sealing process between boxes and lids. It uses tape to seal the packaging, ensuring product safety during transportation. Traditional tape sealing machines typically place the boxes in a fixed frame of the same size and drive it to rotate. A transmission mechanism then pulls out the tape and applies it between the box and lid, completing the sealing operation. However, due to the diverse sizes and specifications of packaging boxes, different products require different box sizes. Traditional tape sealing machines often lack flexible size adjustment mechanisms, making it difficult to adapt to the sealing needs of various box sizes. This means that in actual production, companies may need to equip themselves with multiple tape sealing machines of different specifications to handle the sealing of boxes of varying sizes, increasing equipment purchase costs, occupying significant production space, and creating inconvenience for equipment maintenance and management.

[0031] Example 1:

[0032] like Figures 1 to 3 As shown, this embodiment provides an adjustable-size tape sealing machine, including a worktable 1. A rotating mechanism 5 is installed on the worktable 1. The rotating mechanism 5 is used to drive the packaging box to rotate, so that the tape is wrapped around the packaging box. A positioning frame 6 is also installed on the rotating mechanism 5. The positioning frame 6 is used to place the packaging box. The inner walls on both sides of the positioning frame 6 are provided with sliding grooves 61. Two adjusting plates 62 are slidably connected between the two sliding grooves 61. A trapezoidal screw 63 is connected to one side of the two adjusting plates 62. A first handle 64 is installed at one end of the trapezoidal screw 63. When it is necessary to adjust the size of the positioning frame 6, the operator can turn the first handle 64 to drive the trapezoidal screw 63 to rotate, so that the two adjusting plates 62 slide in opposite directions, thereby realizing the size adjustment of the positioning frame 6 and improving the applicability of the tape sealing machine.

[0033] Specifically, in this embodiment, sliders 65 are installed at both ends of the adjusting plate 62. The sliders 65 are slidably connected to the slide groove 61. A mounting cavity communicating with the slide groove 61 is opened on one side of the positioning frame 6. The sliders 65 extend into the mounting cavity. The trapezoidal screw 63 is located in the mounting cavity and is threadedly connected to the sliders 65. The outer ring threads at both ends of the trapezoidal screw 63 are arranged in opposite directions. The two sliders 65 are located at the two ends of the trapezoidal screw 63 respectively. When the trapezoidal screw 63 rotates, the sliders 65 can drive the two adjusting plates 62 to slide in opposite directions.

[0034] like Figure 4 and Figure 5As shown, the tape sealing machine in this embodiment also includes a limiting mechanism 7. The limiting mechanism 7 specifically includes three first fixing plates 71 arranged vertically. The three first fixing plates 71 are connected by a first guide rod 72. A drive cylinder 73 is installed on the middle first fixing plate 71. The output end of the drive cylinder 73 is connected to a positioning seat 74. A first rotating rod 75 is movably connected to one side of the positioning seat 74. One end of the first rotating rod 75 protrudes from the bottom of the positioning seat 74 and a limiting block 76 is installed. The limiting block 76 is located directly above the positioning frame 6. When the drive cylinder 73 is started, the drive cylinder 73 will drive the positioning seat 74 to move up and down. When adhesive needs to be applied, the limiting block 76 moves down to abut against the packaging box on the positioning frame 6, thereby limiting the packaging box and preventing the packaging box from shifting during the adhesive application process. After the adhesive application is completed, the drive cylinder 73 drives the limiting block 76 to move up to reset, so that the packaging box can be taken out from the positioning frame 6.

[0035] Specifically, in this embodiment, a second rotating rod 77 is rotatably connected between the upper and lower first fixing plates 71. A first pulley 78 is installed on both the first rotating rod 75 and the second rotating rod 77. The first pulley 78 will rotate synchronously with the first rotating rod 75 or the second rotating rod 77. The two first pulleys 78 are connected by a first belt 79. A drive motor 710 is installed inside the workbench 1. The drive motor 710 is connected to the second rotating rod 77. When the drive motor 710 starts, the drive motor 710 will drive the second rotating rod 77 to rotate, and drive the first rotating rod 75 to rotate through the first pulley 78, so that the limiting block 76 can rotate synchronously with the packaging box on the positioning frame 6.

[0036] More specifically, the rotating mechanism 5 in this embodiment includes a third rotating rod 51 movably mounted on the workbench 1. Second pulleys 52 are mounted on both the third rotating rod 51 and the second rotating rod 77. The second pulleys 52 rotate synchronously with either the second rotating rod 77 or the third rotating rod 51. A drive wheel 711 is mounted on the output shaft of the drive motor 710. The drive wheel 711 is connected to the two second pulleys 52 via a second belt 712. A positioning frame 6 is mounted on the top of the third rotating rod 51. When the drive motor 710 starts, the drive wheel 711 drives the two second pulleys 52 to rotate, thereby causing the second rotating rod 77 and the third rotating rod 51 to rotate synchronously. Ultimately, the positioning frame 6 on the third rotating rod 51 rotates synchronously with the limiting block 76 on the first rotating rod 75, thereby driving the packaging box between the positioning frame 6 and the limiting block 76 to rotate stably.

[0037] like Figure 6 and Figure 7As shown, the tape sealing machine in this embodiment also includes a tape applicator 2. The tape applicator 2 specifically includes a support base 21 mounted on the workbench 1. A tape feeding tray 22 and a fourth rotating rod 23 are movably mounted on the support base 21. The tape feeding tray 22 is used to hold the tape, while a first rotating plate 24 is mounted on the fourth rotating rod 23. A second rotating plate 25 is mounted on the first rotating plate 24. An applicator wheel 26 is movably mounted on one end of the second rotating plate 25. The applicator wheel 26 can rotate relative to the second rotating plate 25, stretching the tape on the tape feeding tray 22 to... On the adhesive roller 26, a first electric push rod 27 is also installed on the support base 21. The output shaft of the first electric push rod 27 is hinged to the first rotating plate 24. When the first electric push rod 27 is started, it will drive the first rotating plate 24 to rotate, thereby driving the second rotating plate 25 to rotate, so that the adhesive roller 26 rotates to contact the packaging box on the positioning frame 6, so that the tape on the adhesive roller 26 is attached to the packaging box. At the same time, the rotating mechanism 5 is started, which will drive the packaging box on the positioning frame 6 to rotate, so that the tape is pasted around the packaging box.

[0038] Preferably, the tape sealing machine of this embodiment further includes a tape pressing mechanism 3. The tape pressing mechanism 3 specifically includes a second electric push rod 31 installed on the support base 21, a first clamping block 32 installed at one end of the fourth rotating rod 23, the second electric push rod 31 being hinged to the first clamping block 32, and a third rotating plate 33 installed at the other end of the fourth rotating rod 23. A pressing roller 34 is installed at one end of the third rotating plate 33. The pressing roller 34 can rotate relative to the third rotating plate 33. When the second electric push rod 31 is started, the second electric push rod 31 will drive the fourth rotating rod 23 to rotate through the first clamping block 32, thereby driving the third rotating plate 33 to rotate, so that the pressing roller 34 rotates to contact the packaging box on the positioning frame 6, thereby pressing the tape on the packaging box, so that the tape is firmly attached to the packaging box.

[0039] like Figure 8 As shown, the tape sealing machine in this embodiment also includes a tape cutting mechanism 4. The tape cutting mechanism 4 specifically includes a fifth rotating rod 41 movably mounted on the support base 21. The fifth rotating rod 41 can rotate relative to the support base 21. A second clamping block 42 is installed at one end of the fifth rotating rod 41. A third electric push rod 43 is also installed on the support base 21. The third electric push rod 43 is hinged to the second clamping block 42. A fourth rotating plate 44 is installed at the other end of the fifth rotating rod 41. A cutter 45 is installed at one end of the fourth rotating plate 44. When the third electric push rod 43 is started, the third electric push rod 43 will drive the fifth rotating rod 41 on the second clamping block 42 to rotate. The fifth rotating rod 41 will drive the fourth rotating plate 44 to rotate, so that the cutter 45 rotates until the tape between the adhesive roller 26 and the packaging box contacts, thereby cutting the tape after the adhesive application is completed.

[0040] Example 2:

[0041] The tape sealing machine in this embodiment is basically the same as that in Embodiment 1. The main difference is that this embodiment also has an adjustment mechanism. The adjustment mechanism specifically includes a rotating shaft that is movably installed between the upper and lower first fixing plates 71. The middle part of the rotating shaft is provided with an external thread and is threadedly connected to the middle first fixing plate 71. The top of the rotating shaft protrudes from the upper first fixing plate 71 and is equipped with a second handle. By rotating the second handle, the operator can drive the middle first fixing plate 71 to move up and down, thereby driving the limiting block 76 to move up and down, adjusting the initial position of the limiting block 76 to adapt to different packaging box heights.

[0042] Meanwhile, the adjustment mechanism also includes two second fixed plates installed on the workbench 1, with a second guide rod installed between the two second fixed plates. A slide is installed on the second guide rod, and the support seat 21 is installed on the slide. The slide can drive the support seat 21 to move back and forth along the second guide rod, so that the positional relationship between the tape attaching mechanism 2, the tape pressing mechanism 3, and the tape cutting mechanism 4 on the support seat 21 and the positioning frame 6 can be adapted to different packaging box sizes.

[0043] Preferably, the adjustment mechanism may further include a height adjustment device for the support base 21, which adjusts the height of the support base 21 to accommodate different packaging box heights.

[0044] More preferably, the workbench 1 in this embodiment is also equipped with a controller, which is electrically connected to the drive motor 710, the drive cylinder 73, the first electric push rod 27, the second electric push rod 31 and the third electric push rod 43 respectively. The controller can control each electrical component to realize semi-automatic tape sealing operation.

[0045] It should be stated that the above-described specific embodiments are merely preferred embodiments of this utility model and the technical principles employed. Those skilled in the art should understand that various modifications, equivalent substitutions, and variations can be made to this utility model. However, such variations, as long as they do not depart from the spirit of this utility model, should be within the protection scope of this utility model. Furthermore, some terminology used in this application specification and claims is not limiting, but merely for ease of description.
