Abstract
Description
Technical Field
[0001] This utility model relates to the field of automatic cartoning machine technology, specifically to a three-stage printing mechanism for an automatic cartoning machine with a quick template change function. Background Technology
[0002] An automatic cartoning machine is an automated packaging device used to complete the box-closing action. It is mainly used in the pharmaceutical industry to automatically insert, seal, and attach items and instructions into boxes. The automatic cartoning machine in the workshop uses a steel-frame structure for printing the three-phase printing. During product or batch changes, the three-phase printing module needs to be disassembled and repeatedly adjusted. Specifically, during adjustment, the four screws on the top of the component need to be adjusted sequentially to achieve the appropriate pressure for clear printing of the three phases on the packaging box. Each adjustment wastes hundreds of small packaging boxes and consumes a significant amount of time.
[0003] However, during the use of the existing automatic cartoning machine's third-phase printing mechanism, due to the large market demand for injection solutions and the increasing workshop output, the third-phase printing module needs to be replaced three to four times a day under normal production conditions. Each replacement requires tedious disassembly and adjustment, which not only makes the screws prone to stripping and shortens the service life of parts, but also increases the waste of packaging box materials and wastes a lot of time, resulting in idle work, seriously affecting shift output, and wasting packaging materials and energy.
[0004] Therefore, we propose a three-stage printing mechanism for an automatic cartoning machine with quick template changing to solve the problems mentioned above. Utility Model Content

[0031] 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.
[0032] Please see Figures 1-6 As shown, this utility model provides a technical solution: a three-stage printing mechanism for an automatic cartoning machine with quick template replacement, comprising: a base 1, a nut 2, a first bolt 3, a mating hole 4, a second bolt 5, a mounting groove 6, a sliding groove 7, a limiting rod 8, a limiting seat 9, a third threaded rod 10, a limiting block 11, a printing template body 12, a support frame 13, a fourth threaded rod 14, a hollow retaining ring 15, a pressure sensor 16, a butterfly spring 17, and a display screen 18.
[0033] During the operation of the existing automatic cartoning machine's third-phase printing mechanism, due to the large market demand for injection solutions and the increasing workshop output, the third-phase printing module needs to be replaced three to four times a day under normal production conditions. Each replacement requires tedious disassembly and adjustment, which not only makes the screws prone to stripping and shortens the lifespan of parts, but also increases the waste of packaging materials and time, leading to downtime and seriously affecting shift output, while also wasting packaging materials and energy.
[0034] like Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, the new printing template body 12 is placed in the mounting groove 6 of the base 1. At this time, the mating hole 4 on the side of the printing template body 12 is precisely aligned with the positions of the first bolt 3 and the second bolt 5. The diameter of the mating hole 4 matches the diameter of the bolt, which can achieve initial positioning. Then, the third threaded rod 10 is rotated in the opposite direction, which drives the limiting seat 9 to slide inward along the mounting groove 6. The limiting rod 8 is guided synchronously in the sliding groove 7 until the top of the limiting seat 9 is fully engaged with the limiting block 11 on the lower side of the printing template body 12. The groove of the limiting block 11 and the protrusion of the limiting seat 9 complement each other. After engagement, they can restrict the horizontal movement of the printing template body 12. Finally, the second bolt 5 is tightened to re-embed it into the mating hole 4, and the first bolt 3 is tightened to re-embed it into the mating hole 4, completing the longitudinal and transverse fixation of the printing template body 12. The entire installation process does not require repeated position adjustments, and the positioning accuracy is guaranteed by the structural design.
[0035] It should be noted that the nut 2 can increase the thickness of the base 1, thereby changing the fixing method and fixing it from the outside, fixing the top screw.
[0036] like Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, when replacement is needed, first rotate the second bolt 5. Since the second bolt 5 is threadedly connected to the base 1, during rotation, its end will gradually disengage from the mating hole 4 on the side of the printing template body 12 along the thread direction until it is completely disengaged, releasing the longitudinal constraint on the side of the printing template body 12. At the same time, rotate the first bolt 3 to loosen the lateral engagement between the first bolt 3 and the mating hole 4, further releasing the side fixation of the printing template body 12. At this time, the printing template body 12 is only limited by the quick-release mechanism at the bottom.
[0037] Rotating the third threaded rod 10, which is threadedly connected to the base 1 and rotatably connected to the limiting seat 9, causes the third threaded rod 10 to move outward axially during rotation, pushing the limiting seat 9 to slide horizontally within the mounting groove 6. During this process, the limiting rod 8 fixed at the bottom of the limiting seat 9 simultaneously slides into the sliding groove 7 inside the base 1. The groove 7's direction is consistent with the moving direction of the limiting seat 9, strictly limiting the offset of the limiting rod 8 and ensuring that the limiting seat 9 always moves in a straight line. As the limiting seat 9 slides outward, its top gradually separates from the limiting block 11 on the lower side of the printing template body 12. When the two are completely disengaged, the quick-release mechanism is unlocked.
[0038] At this point, the printing template body 12 is no longer subject to any fixed constraints and can be directly removed from the installation position of the base 1. The entire disassembly process does not require the removal of multiple screws and can be completed by operating only a few parts, which takes less time.
[0039] like Figure 1 , Figure 2 and Figure 6 As shown, if blurry printing occurs during the printing process, the detection mechanism can be adjusted in real time. The hollow retaining ring 15 is attached to the upper side of the base 1, and the pressure sensor 16 embedded inside it is indirectly in contact with the printing end of the printing template body 12. It can sense the pressure value during printing in real time and transmit the electrical signal to the display screen 18. The display screen 18 will display the current pressure in digital form, which is convenient for the operator to judge whether it is within a reasonable range.
[0040] When the display screen 18 indicates insufficient pressure, the fourth threaded rod 14 is rotated. Because the fourth threaded rod 14 is threadedly connected to the support frame 13, and its lower end is tightly fitted with the disc spring 17, the fourth threaded rod 14 moves axially downwards during rotation, compressing the disc spring 17. The disc spring 17 undergoes elastic deformation under pressure, transmitting the pressure to the pressure sensor 16, which then acts on the printing template body 12 through the hollow retaining ring 15, increasing the pressure at the printing end until the display screen 18 shows the pressure has reached a reasonable value. If the pressure is too high, the fourth threaded rod 14 is rotated in the opposite direction, moving it upwards. The disc spring 17 rebounds elastically, reducing the pressure and achieving precise pressure adjustment. The entire process requires no trial printing adjustments and can be operated directly based on the data on the display screen 18, reducing packaging box waste.
