Description

Technical Field

[0001] This utility model relates to the field of labeling machine technology, and in particular to a labeling machine with a positioning structure. Background Technology

[0002] A labeling machine is an automated device used to quickly and accurately affix labels to products or packaging. Widely used in the food, pharmaceutical, and daily chemical industries, it significantly improves production efficiency, reduces labor costs, supports various label types and materials, and possesses high stability and flexibility. In existing technologies, during the use of a labeling machine, the product needs to be placed on a conveyor belt for transport. When the product reaches the labeling position, it is labeled using the labeling components. However, in traditional labeling machines, the product's position shifts during transport on the conveyor belt, resulting in the product not being in the center position upon reaching the labeling position, thus affecting labeling accuracy. Therefore, this invention proposes a labeling machine with a positioning structure to solve the above problems. Utility Model Content

[0003] The purpose of this invention is to address the shortcomings of existing technologies by proposing a labeling machine with a positioning structure.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] A labeling machine with a positioning structure includes a roller conveyor. The roller conveyor includes a body and multiple conveying rollers on the body. The multiple conveying rollers are arranged at equal intervals. A through groove is opened at the lower end of the roller conveyor. Two symmetrically arranged fixed blocks are fixedly connected to the lower end of the roller conveyor. A positioning mechanism for positioning the product on the conveying roller is provided between the two fixed blocks. The positioning mechanism includes a movable plate disposed between the two fixed blocks. Multiple equally spaced limiting rods are fixedly connected to the upper end of each of the two movable plates. The multiple limiting rods pass through the gap between the conveying rollers in sequence and are slidably connected to them. A limiting mechanism for limiting the two movable plates is provided between the two fixed blocks. A moving mechanism for moving the two movable plates is provided between the two fixed blocks.

[0006] Preferably, the limiting mechanism includes a crossbar fixedly connected between two fixed blocks, the crossbar passing through and slidably connected to the movable plates on both sides.

[0007] Preferably, the moving mechanism includes a double-threaded rod rotatably connected between two fixed blocks, the double-threaded rod passing through and threadedly connected to the two moving plates.

[0008] Preferably, a motor is fixedly connected to the side wall of one of the fixing blocks, and the end of the output shaft of the motor is fixedly connected to the end of the double-threaded rod.

[0009] Preferably, a fixed frame is fixedly connected to the upper end of the roller conveyor, a labeling assembly is installed on the inner top of the fixed frame, and infrared sensors are installed on the inner walls of both ends of the fixed frame.

[0010] Preferably, the lower end of the roller conveyor is fixedly connected to four support legs arranged in a rectangular pattern.

[0011] Compared with the prior art, the advantages of this utility model are as follows:

[0012] By setting up a positioning mechanism, when the product is conveyed by the roller conveyor to the labeling component, the output shaft of the motor rotates, driving the double-headed threaded rod to rotate, thereby driving the two moving plates connected to it to move towards the center, and driving the multiple limit rods on both sides to move towards the center, thereby positioning the product and ensuring that the product is in the middle position of the middle roller conveyor during the labeling process, thus ensuring the accuracy of the labeling.

[0020] To make the above-mentioned objectives, features, and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model are described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a full understanding of this utility model. However, this utility model can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this utility model. Therefore, this utility model is not limited to the specific embodiments disclosed below.

[0021] Reference Figure 1-6 A labeling machine with a positioning structure includes a roller conveyor 1, which includes a machine body and multiple conveying rollers 2 on the machine body. The multiple conveying rollers 2 are arranged at equal intervals. A through groove 6 is opened at the lower end of the roller conveyor 1. Two symmetrically arranged fixed blocks 13 are fixedly connected to the lower end of the roller conveyor 1. A positioning mechanism for positioning the product on the conveying rollers 2 is arranged between the two fixed blocks 13. The positioning mechanism includes a movable plate 9 arranged between the two fixed blocks 13. Multiple limit rods 10 arranged at equal intervals are fixedly connected to the upper end of the two movable plates 9. The multiple limit rods 10 pass through the gap between the conveying rollers 2 in sequence and are slidably connected to them.

[0022] Specifically, a limiting mechanism for limiting the movement of the two movable plates 9 is provided between the two fixed blocks 13. The limiting mechanism includes a crossbar 11 fixedly connected between the two fixed blocks 13. The crossbar 11 passes through the movable plates 9 on both sides and is slidably connected to them.

[0023] Specifically, a moving mechanism for moving two movable plates 9 is provided between the two fixed blocks 13. The moving mechanism includes a double-threaded rod 12 rotatably connected between the two fixed blocks 13. The double-threaded rod 12 passes through the two movable plates 9 and is threadedly connected to them. A motor 3 is fixedly connected to the side wall of one of the fixed blocks 13. The end of the output shaft of the motor 3 is fixedly connected to the end of the double-threaded rod 12.

[0024] Specifically, a fixed frame 4 is fixedly connected to the upper end of the roller conveyor 1. A labeling component 8 is installed on the inner top of the fixed frame 4. Infrared sensors 7 are installed on the inner walls of both ends of the fixed frame 4. Four rectangular support legs 5 are fixedly connected to the lower end of the roller conveyor 1. The infrared sensors 7 are connected to the controller of the motor 3. When the infrared sensors 7 sense that the product has reached the appropriate position, the motor 3 starts and the roller conveyor 1 stops conveying the product. The infrared sensors 7 are connected to the controller of the roller conveyor 1. When the infrared sensors 7 sense that the product has reached the appropriate position, the roller conveyor 1 stops.

[0025] When using this utility model, the worker first places the product on the conveyor roller 2 of the roller conveyor 1 for conveying. When the product reaches the fixed frame 4, the infrared sensor 7 senses that the product has reached the appropriate position, the roller conveyor 1 stops, the motor 3 starts, and the output shaft of the motor 3 rotates, which drives the double-headed threaded rod 12 to rotate. The rotation of the double-headed threaded rod 12 drives the two moving plates 9 connected to it to move towards the middle, which drives the multiple limit rods 10 on both sides to move towards the middle, thereby positioning the product and ensuring that the product is in the middle position of the roller conveyor 1 during the marking process, thus ensuring the accuracy of the marking. After the marking is completed, the roller conveyor 1 starts again to output the product.

[0026] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
