TECHNICAL FIELD
[0001] The present application relates to the technical field of packaging equipment, in particular to the technical field of the core of a carton sealing machine. BACKGROUND
[0002] The traditional core of a carton sealing machine is characterized by the provision of pressure wheels at positions before and after the adhesive tape path, and by a linkage mechanism that ensures the synchronous operation of these pressure wheels, thereby ensuring the smoothness and efficiency of the packaging process. The cutting tool in such equipment usually adopts a fixed structure, so in the conventional design, only a simple rear limiting device needs to be provided at the rear pressure wheel to meet the use requirements. As shown in Figure 1 and Figure 2 The rear limiting device 100 in the figure is added for comparison and illustration, and of course it can also be added for use in the present application according to requirements.
[0003] However, with the advancement of technology and the higher pursuit of safety, an innovative design introduces a guard structure on the cutting tool. Although this improvement significantly improves the safety of operation, it also brings new challenges: due to the presence of the guard structure, the linkage will also be subjected to additional forces in the middle. This not only increases the mechanical stress, but also puts higher requirements on the overall stability.
[0004] Therefore, the traditional limiting design has been unable to meet the use requirements under the new circumstances, prompting the industry to seek more stable and reliable limiting structure solutions to adapt to this change. SUMMARY
[0005] In view of the above-mentioned requirements, the present application proposes a core of a carton sealing machine, which is improved from the limiting structure to improve the overall stress stability of the carton sealing machine with a guard structure.
[0006] To achieve the above-mentioned purposes, the following technical solutions are adopted in the present application:

[0009] A cutting tool structure is provided between the front pressure wheel and the rear pressure wheel, the cutting tool structure being provided with a guard structure, the guard structure being connected with the main linkage and rotated synchronously;
[0010] At least one limiting structure that limits the rotation of the main linkage is provided above the main linkage and between the front pressure wheel and the rear pressure wheel in the rack.
[0011] Thus, the mechanical stress of the main connecting rod caused by the synchronous rotation of the front pressing wheel, the rear pressing wheel and the guard structure can be evenly distributed, and fatigue deformation caused by long-term use can be avoided.
[0012] In some possible embodiments, the limiting structure is arranged at least one of between the front pressing wheel and the guard structure and between the rear pressing wheel and the guard structure.

[0016] In some possible embodiments, the limiting structure is an eccentric wheel. The limiting can play a buffering role.
[0017] In a preferred embodiment, the eccentric wheel is arranged between the rear pressing wheel and the guard structure.
[0018] In some possible embodiments, the limiting structure is an adjustable limiting bolt and / or an eccentric wheel.
[0019] In some possible embodiments, the rear limiting device is further included. BRIEF DESCRIPTION OF DRAWINGS

[0024] The features and other related features of the present application are further described in detail by the following examples, so as to facilitate the understanding of the skilled in the art:
[0025] It should be noted that the words "front", "rear", "left", "right", "upper" and "lower" used in the following description refer to the directions in the drawings, and the words "bottom surface" and "top surface", "inner" and "outer" refer to the directions towards or away from the geometric center of a particular component.
[0026] Further, unless otherwise expressly specified and limited, the terms "mounting", "connecting", "connection" should be understood broadly, for example, can be fixed connection, can also be detachable connection, or integrally connected; can be directly connected, or indirectly connected through an intermediate medium, can be internal communication of two elements. For those skilled in the art, the specific meaning of the above terms in this case can be understood according to the specific circumstances.
[0027] The sealing machine core is a relatively mature device in the field of packaging equipment. The conventional prior art is provided with front and rear pressing wheels, and a cutter structure is arranged in the middle. The front and rear pressing wheels are connected by a connecting rod to realize synchronous rotation, and the cutter structure is used to cut off the adhesive tape. At this time, the rear pressing wheel side bears the most stress, so a limiting structure is arranged at the rear pressing wheel to prevent the front and rear pressing wheels from rotating too much and causing damage. As shown in Figure 1 and Figure 2 The rear limiting device 100 in the figure is added for comparison and illustration, and of course it can also be added and used in this application according to the requirements.
[0028] However, this way of operation has the risk of injury to the staff because the cutter structure is always exposed. Products with a guard structure have also been developed, and the guard structure can continue to apply the connecting rod structure of the front and rear pressing wheels for rotation. At this time, at least the following two problems exist. First, the overall connecting rod is subjected to stress at at least three places instead of two ends, which leads to mechanical stress unevenness and hidden dangers of mechanical fatigue after long-term use. Second, it is difficult to adjust the cooperation between the guard structure and the front and rear pressing wheels, and these two points are the problems to be improved in this application.
[0029] Please refer to Figure 1 and Figure 2 The sealing machine core of the present application comprises a rack 1, and the rack 1 is provided with an adhesive tape wheel 2, a guide roller set 3, a front pressing wheel 4 and a rear pressing wheel 5. The adhesive tape passes through the guide roller set 3, the front pressing wheel 4 and the rear pressing wheel 5 in sequence after being released from the adhesive tape wheel 2. Here, the application of the adhesive tape wheel 2 and the guide roller set 3 is an industry common technical means to make the release of the adhesive tape smooth and keep the tension, which will not be described here.
[0030] Please refer to Figure 2 The front pressing wheel 4 and the rear pressing wheel 5 are connected by a main connecting rod 6 and rotate synchronously. At this time, the main connecting rod 6 and the rear pressing wheel 5 are fixed shaft connections, and the main connecting rod 6 and the front pressing wheel 4 are movable shaft connections. That is, at this time, the front pressing wheel 4 can be understood as a driving wheel, and the rotating shaft of the main connecting rod 6 is on the side of the rear pressing wheel 5, that is, the rear pressing wheel 5 is a driven wheel. Therefore, in the conventional design, the limiting structure is arranged on the side of the rear pressing wheel 5.
[0031] The present application sets a guard structure 8 on the cutter structure 7 between the front pressing wheel 4 and the rear pressing wheel 5, and the guard structure 8 is connected with the main connecting rod 6 and rotates synchronously. In the present application, the synchronous rotation is realized by the application of the guide groove 81, and in some other embodiments, the cam structure or the gear structure can also be used to realize the synchronous rotation, which is not limited in the present application.
[0032] Further, the main connecting rod 6 is located above the frame 1, and between the front pressing wheel 4 and the rear pressing wheel 5, at least one limiting structure 9 is arranged to limit the rotation of the main connecting rod 6, that is, to prevent it from rotating too much. More specifically, the limiting structure 9 is arranged at least one of the positions between the front pressing wheel 4 and the guard structure 8 and between the rear pressing wheel 5 and the guard structure 8, because the guide groove 81 is arranged at the guard structure 8 to realize the synchronous rotation, it is not convenient to arrange the limiting structure 9.
[0033] In this way, the mechanical stress of the main connecting rod 6 caused by the synchronous rotation of the front pressing wheel 4, the rear pressing wheel 5 and the guard structure 8 can be relatively evenly distributed, and the fatigue deformation caused by long-term use can be avoided.
[0034] Please refer to Figure 3 and Figure 4 As described above, the stress near the rear pressing wheel 5 side will increase, and at the same time, there is a need to adjust the rotation angle of the main connecting rod 6, different limiting structures 9 can be used.
[0035] As an adjustable way, the limiting structure 9 can be an adjustable limiting bolt 91, which can be adjusted according to the actual application requirements. Further, the adjustable limiting bolt 91 is arranged between the front pressing wheel 4 and the guard structure 8, and the limiting bolt 91 is arranged towards the side of the guard structure 8, so that the stress it bears is relatively light. A buffer pad can be additionally arranged at the contact position of the limiting bolt 91 and the main connecting rod 6, which is not shown in the figure.
[0036] And between the rear pressing wheel 5 and the guard structure 8, an eccentric wheel 92 can be used, which can also play a buffering role when limiting.
[0037] Of course, in other embodiments, the positions of the limiting bolt 91 and the eccentric wheel 92 described above can be used interchangeably. That is, the limiting bolt 91 or the eccentric wheel 92 can be used alone between the front pressing wheel 4 and the guard structure 8, or the limiting bolt 91 or the eccentric wheel 92 can be used between the rear pressing wheel 5 and the guard structure 8. Of course, the limiting bolt 91 and the eccentric wheel 92 can also be used at the same time.
[0038] As described above, the present application protects a packaging machine core, and all technical solutions that are the same or similar to the present application should be considered to fall within the protection scope of the present application.
