Specific embodiments

[0024] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of the present utility model.

[0025] Embodiment: As Figures 1-5 shown, a conveying structure for a high - speed multi - functional trademark printing machine includes a conveying table 1 and a trademark printing machine 2. A top roller 101 is rotatably installed at the front end of the conveying table 1. The trademark printing machine 2 is installed on the conveying table 1 and is located directly below the top roller 101. Two longitudinal first limiting grooves 102 are opened on the conveying table 1. Two first electric push rods 103 are fixedly installed at the rear end of the conveying table 1, and a shaft seat 104 is fixedly installed at the telescopic end of the first electric push rod 103. Guide rollers for guiding the trademark tape are rotatably installed on the left and right sides at the front end of the conveying table 1 in a mirror image manner. A limiting component 3 for guiding and limiting the trademark tape is further installed on the conveying table 1;

[0026] The adjusting assembly 4 for adjusting the tension of the trademark tape is installed on the conveyor table 1. There are two adjusting assemblies 4, which are respectively located at two first limiting slots 102. The adjusting assembly 4 includes a mounting seat 401, a channel steel 402 and a scissors frame 403. There are two mounting seats 401, and a telescopic rod 404 is fixedly installed between the two mounting seats 401. A plurality of second electric push rods 405 are fixedly installed between the two mounting seats 401. The scissors frame 403 is rotatably installed between the channel steel 402 and the scissors frame 403. A second shaft rod 408 is fixedly installed at the top of the channel steel 402, and an adjusting roller 409 is rotatably installed on the second shaft rod 408. During use, control the second electric push rod 405 to expand and contract. When the second electric push rod 405 extends, the angle between the scissors frames 403 becomes larger, and the adjusting roller 409 contracts towards the telescopic rod 404, and vice versa, so as to achieve the purpose of adjusting the tension between the trademark tapes.

[0027] There are two limiting assemblies 3, which are respectively located directly above the two guiding rollers. During use, the guiding rollers are used to guide the transmission direction of the trademark tape.

[0028] The limiting assembly 3 includes a mounting plate 301 and an adjusting screw 302. The mounting plate 301 is fixedly installed at the front end of the conveyor table 1. A first shaft rod 303 is movably inserted into the mounting plate 301. A pressing roller 304 is rotatably installed on the first shaft rod 303. Moving plates 305 are fixedly installed at both ends of the first shaft rod 303. The adjusting screw 302 is rotatably installed at the top of the mounting plate 301. The adjusting screw 302 is threadedly connected to the moving plate 305. A rotating handwheel 307 is fixedly welded to the top of the adjusting screw 302. A spring 306 is fixedly installed between the moving plate 305 and the mounting plate 301. During use, rotate the adjusting screw 302 by rotating the rotating handwheel 307. The rotation of the adjusting screw 302 drives the moving plate 305 to move downward. The downward movement of the moving plate 305 drives the pressing roller 304 to move downward through the first shaft rod 303, so as to press the trademark tape against the guiding roller to limit the guiding, and the elastic effect of the spring 306 can increase the friction between the adjusting screw 302 and the moving plate 305, thereby preventing the adjusting screw 302 from slipping threads.

[0029] Two first electric push rods 103 are fixedly installed at the rear end of the conveyor table 1, and a shaft seat 104 is fixedly installed at the telescopic end of the first electric push rod 103. One of the mounting seats 401 is rotatably connected to the shaft seat 104. During use, the telescopic action of the first electric push rod 103 is used to drive the adjusting assembly 4 to move up and down to achieve large-range tension adjustment.

[0030] There are multiple channel steels 402 and scissors frames 403, which are arranged in an equidistant circular array with the mounting seat 401 as the center. A second limiting groove 406 for limiting the scissors frame 403 is provided on the channel steel 402. One end of the scissors frame 403 is provided with a convex column 407, and the convex column 407 is slidably installed in the second limiting groove 406. During use, the scissors frame 403 is limited by the sliding action of the second limiting groove 406 and the convex column 407, so that the channel steel 402 will expand outwards when the scissors frame 403 rotates.

[0031] Pressure sensors for testing tension are installed between both ends of the second shaft rod 408 and the channel steel 402. During use, the pressure of the trademark conveyor belt on the adjusting roller 409 is detected by the pressure sensors, so as to indirectly detect the tension of the trademark winding belt.
