DETAILED DESCRIPTION

[0023] In order to more clearly understand the above-mentioned purpose, features and advantages of the utility model, the utility model is further explained below in conjunction with drawings and embodiments. It should be explained that the embodiments of the application and the features in the embodiments can be combined with each other without conflict.

[0024] In the following description, a lot of specific details are set forth in order to fully understand the utility model, but the utility model can also be implemented in other ways different from the description, therefore, the utility model is not limited to the specific embodiments disclosed in the following disclosure.

[0025] Embodiment one: as shown in Figures 1-4 The utility model provides a label pressfitting mechanism of labeling machine of liquid agent filling production line, including mounting bracket 1, mounting bracket 1 top fixedly connected with support frame 3, support frame 3 inside central installation has drive motor 5, and mounting bracket 1 top installation has drive mechanism 2, and support frame 3 both sides all are equipped with pressfitting subassembly 4;

[0026] Drive mechanism 2 includes belt transmission part 21 and two reciprocating plates 23, and belt transmission part 21 is fixedly connected with drive motor 5 output end, and both ends bottom of belt transmission part 21 are fixedly connected with rotating rod 22, and rotating rod 22 is rotatably connected with support frame 3, and the bottom of rotating rod 22 is fixedly connected with crank 26, and one end bottom of crank 26 is fixedly connected with drive rod 24, and reciprocating plate 23 middle part is equipped with push groove 27, and drive rod 24 is slidably connected with push groove 27, and one side central of reciprocating plate 23 is fixedly connected with push rod 25, and one end outer surface of push rod 25 is slidably connected with limiting frame 28.

[0027] Pressfitting mechanism includes control frame 41, and control frame 41 bottom end inside is equipped with moving block 42, and moving block 42 bottom end penetrates support frame 3, and moving block 42 is fixedly connected with one end of push rod 25.

[0028] The specific settings and effects of this embodiment will be discussed below. First, when the drive motor 5 is started, its power is transmitted through the belt transmission part 21. The belt transmission part 21 evenly distributes this power to the two rotating rods 22 that rotate synchronously. The crank 26, driven by the rotating rod 22, performs precise circular motion. Through the sliding action of the drive rod 24 inside the push groove 27, and at the same time, the precise force is applied to the reciprocating plate 23. The diameter of the bottom end of the drive rod 24 is designed to be larger than the inner width of the limiting groove 48, which not only enhances the stability of the structure, but also ensures that the drive rod 24 can accurately control the motion trajectory of the reciprocating plate 23.

[0029] With the continuous rotation of the crank 26, the reciprocating plate 23 realizes precise linear reciprocating motion under the joint action of the push rod 25 and the limiting frame 28. This ensures the accuracy and consistency of each pressing action. More importantly, the synchronous rotation of the two cranks 26 allows the two reciprocating plates 23 to approach or move away from each other, thereby achieving precise control of the pressing plates 49 on both sides of the filled container.

[0030] During the pressing process, this approach-avoid motion pattern ensures uniform adhesion of the label on the surface of the filled container, avoiding the generation of bubbles, wrinkles, and other problems. At the same time, due to the uniform and controllable pressure applied by the pressing plates 49, the adhesion between the label and the container is more compact and firm, greatly improving the overall quality of the product.

[0031] Embodiment two: as shown in Figure 1 and Figure 2As shown, the top end of the support frame 3 is slidingly connected with a movable rod 46, and one end of the movable rod 46 is fixedly connected with a pressing plate 49. The outer surface of one end of the movable rod 46 is fixedly connected with a connecting block 47, and the outer surface of the connecting block 47 is provided with a limiting groove 48. The inner side of the control frame 41 is rotationally connected with a rotating frame 44, and one end of the rotating frame 44 is fixedly connected with the support frame 3. The top end of the control frame 41 is rotationally connected with a second driving block 45, and the second driving block 45 is located in the limiting groove 48. The bottom end of the control frame 41 is provided with a clamping groove 411, and the clamping groove 411 is slidingly connected with a first driving block 43. The first driving block 43 is rotationally connected with the side wall of the moving block 42, and the inner side of the moving block 42 is slidingly connected with a sliding rod 421, and the sliding rod 421 is fixedly connected with the support frame 3.

[0032] The effect of the whole embodiment is that in the fine process of pressing operation, the moving block 42 moves stably and accurately along the smooth surface of the sliding rod 421 with the accurate driving of the pushing rod 25. With the continuous movement of the moving block 42, the sliding of the first driving block 43 in the clamping groove 411 gradually converts into the torque action on the control frame 41, and the control frame 41 rotates around the rotating frame 44 as the axis. At the same time, the second driving block 45 at the top end of the control frame 41 is precisely matched with the limiting groove 48. While the control frame 41 rotates, the second driving block 45 cooperates with the limiting groove 48 to apply force to the connecting block 47.

[0033] Finally, the rotating motion of the control frame 41 is converted into the sliding of the movable rod 46 in the inner side of the top end of the support frame 3 through the connecting block 47. The sliding of the movable rod 46 directly drives the pressing plate 49 to slowly approach the filling container until reaching the predetermined pressing position. In this process, the pressing plate 49 not only plays an accurate positioning role on the container, but also ensures the smooth pressing operation, effectively avoiding the problem of poor pressing caused by position deviation or uneven force.

[0034] The working principle and method of using the device are as follows: when the pressing operation is performed, the driving motor 5 is first started to drive the belt transmission member 21 to rotate, and then drive the two rotating rods 22 to rotate synchronously. With the rotation of the rotating rod 22, the crank 26 is driven to move in a circle. This movement makes the driving rod 24 rotate around the rotating rod 22 and slide in the pushing groove 27 while applying force to the reciprocating plate 23. Due to the limitation of the limiting frame 28, the pushing rod 25 can stably move in a straight line.

[0035] The diameter of the bottom end of the driving rod 24 is designed to be larger than the inner width of the limiting groove 48, which ensures that the driving rod 24 can stably control the motion trajectory of the reciprocating plate 23. At the same time, the circular motion of the crank 26 drives the reciprocating plate 23 to move in a straight line.

[0036] On the other hand, during the pressing process, the moving block 42 moves linearly along the surface of the slide rod 421 under the drive of the push rod 25. During this process, the first drive block 43 exerts force on the control frame 41 and uses its rotation and sliding ability to move flexibly inside the clamping groove 411. As the moving block 42 continues to move, the first drive block 43 gradually drives the control frame 41 to rotate around the rotating frame 44.

[0037] During the rotation of the control frame 41, the second drive block 45 at the top end cooperates with the limiting groove 48 to exert force on the connecting block 47. This force is transmitted to the movable rod 46 through the connecting block 47, causing the movable rod 46 to slide inside the top end of the support frame 3, thereby gradually approaching the filling container.

[0038] Finally, when the two cranks 26 rotate, they will drive the reciprocating plate 23 to move towards or away from each other. This movement, through the ingenious design of the mechanical structure, indirectly controls the pressing force of the two pressing plates 49 on the surface of the filling container, making the attached label more firm and flat.

[0039] The above is only a preferred embodiment of the present application, and is not intended to limit the present application in other forms. Any skilled person in the art can modify or change the above disclosed technical content to equivalent embodiments applied to other fields, but any simple modification, equivalent change and modification of the above embodiments within the technical content of the present application, according to the technical essence of the present application, still belongs to the protection scope of the present application.
