Description

Technical Field

[0001] This utility model belongs to the field of packaging box production technology, and in particular relates to a color printing paper positioning mechanism with adjustable cutting accuracy. Background Technology

[0002] Packaging boxes refer to rigid or semi-rigid containers, and colored printed paper is one of the main raw materials for packaging boxes. Packaging boxes are obtained by cutting, folding and gluing colored printed paper. In order to facilitate the cutting of colored printed paper, a positioning mechanism is generally used to position the cutting position of the colored printed paper. A paper positioning mechanism for printing is disclosed in a document with the existing authorization announcement number CN221607251U. The mechanism includes a base, with a second fixing plate fixedly connected to both the front and rear ends of the left side of the base. A motor is fixedly installed on the front of one of the second fixing plates. The output end of the motor passes through the front of the second fixing plate and is fixedly connected to a rotating shaft. A worm gear is provided at the center of the surface of the rotating shaft. However, it still has the following drawbacks in practical use: 1. The printing paper positioning mechanism mentioned above drives the positioning plate to move through the bidirectional threaded rod, thereby positioning the color printing paper. However, in use, it can only position the paper cutting position in the front-back direction, and it is not convenient to position the paper cutting position in the left-right direction. The cutting accuracy is low and the practicality is poor. 2. The paper positioning mechanism mentioned above guides the colored printing paper through a guide roller and positions it using a positioning plate. However, since the colored printing paper is used to make packaging boxes and is generally quite thick, the positioning mechanism cannot assist the blade in cutting the colored printing paper, resulting in poor functionality.

[0003] To address these issues, we provide a color printing paper positioning mechanism with adjustable cutting precision. Utility Model Content

A lower guide roller 303 is rotatably connected between the front and rear adjacent mounting columns 301. An upper guide roller 305 is movably connected between the front and rear adjacent mounting columns 301. A third threaded rod 304 is rotatably connected in the groove of the mounting column 301. The top end of the third threaded rod 304 extends above the mounting column 301 and is fixedly connected to a second handwheel 304b. The bottom end of the third threaded rod 304 extends below the mounting column 301 and is fixedly connected to a second synchronous pulley 304c. The second synchronous pulleys 304c are connected to each other by a second synchronous belt 304d. The front and rear ends of the upper guide roller 305 are movably connected to second sliders 304a. The free end of the second slider 304a is threadedly connected to the outer wall of the third threaded rod 304.

[0033] The operation process of this embodiment is as follows: the drive motor 203b is started, and the output shaft of the drive motor 203b drives the moving block 203 and the positioning plate 204 to move through the second threaded rod 203d, so that the positioning plate 204 and the positioning groove 204a move to above the paper cutting position, and the infrared transmitter 205 is started, so that the infrared transmitter 205 emits an infrared signal. When the infrared receiver 206 does not receive an infrared signal, it means that the blade is located in the positioning groove 204a. When the infrared receiver 206 receives an infrared signal, it means that the blade is not located in the positioning groove 204a, thereby improving the accuracy of paper cutting.

[0034] Example 2 Please see Figure 1 , Figure 7 , Figure 8 and Figure 9 As shown, this is the second embodiment of the present invention.

The installation plate 402 and sleeves 403 are used to limit the movement of the perforating needles 405. The lifting plate 404 is used to drive the perforating needles 405 to rise and fall. The perforating needles 405 are used to perforate the paper, thereby facilitating the cutting of the paper.

[0036] Furthermore, a second mounting seat 401a is fixedly connected to both sides of the front and rear end faces of the positioning platform 1, and a slide rod 401b is fixedly connected between adjacent second mounting seats 401a.

The bottom end of the fixing rod 405b passes through the lifting plate 404 and is threadedly connected to the fastening nut 405c. The fastening nut 405c is attached to the lower surface of the lifting plate 404.

[0037] The rest of the structure is the same as in Example 1.

[0038] The operation process of this embodiment is as follows: an external force is applied to the movable column 401, causing the movable column 401 to move the mounting plate 402 and the perforating needle 405 to below the paper cutting position, and the hydraulic cylinder 404a is activated. The output shaft of the hydraulic cylinder 404a drives the lifting plate 404 and the perforating needle 405 to move through the third slider 404b, so that the tip of the perforating needle 405 passes through the sleeve 403 and pierces the paper, thereby realizing the perforation of the paper cutting position and facilitating the cutting of the paper.
