Description

Technical Field

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

[0002] Marking machines are a common processing method in sheet metal processing, mainly used to mark cutting lines, drilling positions, or other processing reference lines on sheet metal.

[0003] In the prior art, traditional marking machines require conveying the board material during use, and marking is performed during the conveying process. Traditional marking machines use conveyor belts for conveying, but due to the lack of positioning, the conveying position of the board material is not uniform and it is difficult to place it in the center of the conveyor belt, resulting in inaccurate marking positions. Therefore, this utility model proposes a positioning mechanism for a marking machine to solve the above problems. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a positioning structure for a marking machine.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A positioning structure for a marking machine includes a base, with a roller conveyor fixedly connected to the upper end of the base. Multiple equally spaced conveying rollers are installed inside the roller conveyor. A positioning mechanism for positioning workpieces on the conveying rollers is provided inside the roller conveyor. The positioning mechanism includes two positioning plates arranged symmetrically inside the roller conveyor, and three equally spaced positioning rods are rotatably connected to the upper ends of each of the two positioning plates. The positioning rods are respectively inserted into the gaps between the multiple conveying rollers. A limiting mechanism for limiting the positioning mechanism is provided inside the roller conveyor. A driving mechanism for driving the positioning mechanism is provided at the upper end of the base.

[0007] Preferably, the limiting mechanism includes two limiting rods fixedly connected between the inner walls of both ends of the roller conveyor, and both limiting rods pass through two positioning plates and are slidably connected to them.

[0008] Preferably, the drive mechanism includes a motor fixedly connected to the upper end of the base, and a gear is fixedly connected to the end of the output shaft of the motor.

[0009] Preferably, a rack is fixedly connected to one end of each of the two positioning plates, and the two racks mesh with the two sides of the gear respectively.

[0010] Preferably, the upper end of the roller conveyor is fixedly connected to two symmetrically arranged vertical plates, and the upper ends of the two vertical plates are jointly fixedly connected to a top plate.

[0011] Preferably, the lower end of the top plate is fixedly connected to two symmetrically arranged electric push rods, and the telescopic ends of the two electric push rods are fixedly connected to a movable plate, and a marking assembly is installed at the lower end of the movable plate.

[0012] Compared with the prior art, the advantages of this utility model are as follows:

[0013] 1. By setting up a positioning mechanism and a driving mechanism, when the board passes through the positioning mechanism, the output shaft of the drive motor rotates, which drives the gear to rotate. Under the action of the gear, the two meshing racks move in opposite directions, which drives the positioning plates on both sides to move towards the middle, and drives the positioning rods on both sides to move towards the middle, thus limiting the board that passes through and ensuring that it is in the middle position on the roller conveyor, thus ensuring the accuracy of the marking.

[0014] 2. By setting a limiting mechanism, the positioning plate can slide on two limiting rods. The setting of the limiting rods can limit the positioning plates on both sides, thereby improving the stability of the two positioning plates and improving the positioning stability.

[0021] 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.

[0022] Reference Figure 1-5 A positioning structure for a marking machine includes a base 1, with a roller conveyor 5 fixedly connected to the upper end of the base 1. Multiple equally spaced conveying rollers 4 are installed inside the roller conveyor 5. A positioning mechanism for positioning the workpieces on the conveying rollers 4 is provided inside the roller conveyor 5. The positioning mechanism includes two positioning plates 12 arranged symmetrically inside the roller conveyor 5. Three equally spaced positioning rods 9 are rotatably connected to the upper ends of the two positioning plates 12. The multiple positioning rods 9 are respectively inserted into the gaps between the multiple conveying rollers 4.

[0023] In this utility model, the roller conveyor 5 is provided with a limiting mechanism for limiting the positioning mechanism. The limiting mechanism includes two limiting rods 14 fixedly connected between the inner walls of both ends of the roller conveyor 5. Both limiting rods 14 pass through two positioning plates 12 and are slidably connected to them. One end of each of the two positioning plates 12 is fixedly connected to a rack 13. The two racks 13 mesh with the two sides of the gear 11 respectively.

[0024] In this utility model, the upper end of the base 1 is provided with a drive mechanism for driving the positioning mechanism. The drive mechanism includes a motor 10 fixedly connected to the upper end of the base 1, and a gear 11 is fixedly connected to the end of the output shaft of the motor 10.

[0025] In this utility model, the upper end of the roller conveyor 5 is fixedly connected to two symmetrically arranged vertical plates 2, the upper ends of the two vertical plates 2 are jointly fixedly connected to a top plate 3, the lower end of the top plate 3 is fixedly connected to two symmetrically arranged electric push rods 6, the telescopic ends of the two electric push rods 6 are jointly fixedly connected to a moving plate 7, and the lower end of the moving plate 7 is equipped with a marking assembly 8.

[0026] In use, the sheet material is placed on the roller conveyor 5 for conveying. When the sheet material passes the positioning mechanism, the output shaft of the drive motor 10 rotates, driving the gear 11 to rotate. Under the action of the gear 11, the two meshing racks 13 move in opposite directions, driving the positioning plates 12 on both sides to move towards the middle, and driving the positioning rods 9 on both sides to move towards the middle, thus limiting the passing sheet material and ensuring that it is in the middle position on the roller conveyor 5, ensuring the accuracy of the marking. The positioning plates 12 can slide on the two limiting rods 14. The setting of the limiting rods 14 can limit the positioning plates 12 on both sides, thereby improving the stability of the two positioning plates 12. When the sheet material passes under the top plate 3 after being limited, the telescopic end of the drive electric push rod 6 extends, driving the moving plate 7 and the marking assembly 8 to move down, adjust the position, and perform marking on the sheet material.

[0027] 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.
