[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Please see Figures 1-6 This utility model provides an embodiment of a conveying mechanism for automatic centering and tension balancing of decorative paper rolls, comprising a mechanism mounting frame 1, auxiliary sub-rollers 402, and a roll centering adjustment component; a top fixing plate 2 is fixedly connected to the upper end of the mechanism mounting frame 1, and a roll centering adjustment component is provided below the top fixing plate 2; a drive motor 3 is installed on the side end face of the mechanism mounting frame 1, and the output shaft of the drive motor 3 passes through the mechanism mounting frame 1 and is fixedly connected to the central shaft of the take-up roller 4; the exterior of the take-up roller 4 is covered with a decorative paper roll body 5; a fixed crossbar 6 is fixedly connected to the inner wall of the mechanism mounting frame 1; a pivot main roller 401 is rotatably connected to the outer end of the fixed crossbar 6; auxiliary sub-rollers 402 are rotatably connected to the inner sides of the pivot main roller 401; a bottom mounting block 403 is installed on the inner wall of the bottom end of the mechanism mounting frame 1; and extension rods 404 are fixedly connected to the lower ends of the pivot main roller 401.

[0025] A tension spring 405 is hinged to the lower end of the extension rod 404. The side end of the tension spring 405 is hinged to the side end of the bottom mounting block 403. A guide center roller 406 is rotatably connected to the inner side of the mechanism mounting frame 1. When the tension of the decorative paper roll body 5 changes, the auxiliary sub-rollers 402 on both sides of the hub main roller 401 will rotate accordingly to adapt to the change of the roll body 5, depending on whether the decorative paper roll body 5 is being wound or unwound. The tension spring 405 connected to the extension rod 404 on both sides of the lower end of the hub main roller 401 will play a buffering and adjustment role for the auxiliary sub-rollers 402, which can meet the tension balance adjustment during the winding and unwinding conveying process.

[0026] The outer curved surface of the guide center roller 406 is symmetrically provided with mounting blocks 407. The inner side of the mounting blocks 407 is hinged with a movable short plate 408. The outer curved surface of the guide center roller 406 is fixed with a rubber bearing block 409. The upper end of the rubber bearing block 409 is hinged to the inner end of the movable short plate 408. The upper end of the movable short plate 408 is hinged with a fan-shaped contact plate 410. When the tension of the roll material changes, causing a change in contact pressure, the fan-shaped contact plate 410 will be squeezed. Then, the fan-shaped contact plate 410 will transmit the squeezing force to the rubber bearing block 409 through the lower hinged movable short plate 408. At this time, deformation will occur, and the position of the fan-shaped contact plate 410 will also change, which plays a role in assisting in adjusting the effect of the roll material.

[0027] A top vertical plate frame 411 is fixedly connected to the upper end of the top fixed plate 2. A guide groove 412 is provided on the inner side of the top vertical plate frame 411. A U-shaped lifting plate 413 is slidably connected inside the guide groove 412. An upper extrusion roller 414 is rotatably connected to the inner side of the U-shaped lifting plate 413. An electric telescopic rod 415 is installed at the upper end of the top vertical plate frame 411. The output end of the electric telescopic rod 415 passes through the top vertical plate frame 411 and is fixedly connected to the top of the U-shaped lifting plate 413. The electric telescopic rod 415 can control the U-shaped lifting plate 413 to slide in the guide groove 412, thereby driving the upper extrusion roller 414 to move up and down.

[0028] A support sleeve 416 is fixedly connected to the inner wall of the bottom end of the mounting frame 1. A pressure spring 417 is installed inside the support sleeve 416. A damper is connected to the upper end of the pressure spring 417. A movable inner support plate 418 is connected to the upper end of the damper. A lower extrusion roller 419 is rotatably connected to the inner side of the movable inner support plate 418. A limit groove 420 is opened at the side end of the support sleeve 416. A connecting short rod 421 is slidably connected inside the limit groove 420. The connecting short rod 421 is connected to the side end of the movable inner support plate 418. The lower extrusion roller 419 is installed on the movable inner support plate 418. The pressure spring 417 and the damper below the movable inner support plate 418 can buffer the changes in the tension of the roll material. The upper extrusion roller 414 and the lower extrusion roller 419 cooperate with each other to apply pressure to the roll material and prevent the roll material from being excessively loose or stretched.

[0029] The roll material centering adjustment assembly includes a guide slot 201, a connecting rod 202, an arc-shaped actuating plate 203, a connecting block 204, and a two-way cylinder 205. Two guide slots 201 are symmetrically opened inside the top fixed plate 2. The connecting rod 202 is slidably connected inside the two guide slots 201. The lower end of the connecting rod 202 is fixed to the arc-shaped actuating plate 203. The connecting rod 202 and the guide slot 201 cooperate to limit the arc-shaped actuating plate 203.

[0030] A connecting block 204 is fixedly connected to the upper end of the connecting rod 202. A bidirectional cylinder 205 is installed on the upper surface of the top fixing plate 2. The output end of the bidirectional cylinder 205 is fixedly connected to the inner end of the connecting block 204. The bidirectional cylinder 205 pushes the connecting block 204, and the connecting block 204 drives the connecting rod 202 to slide in the guide slot 201. The arc-shaped actuating plate 203 at the lower end of the connecting rod 202 moves accordingly to actuate and adjust the decorative paper roll body 5.

[0031] Working principle: According to Figures 1-5 First, the drive motor 3 drives the take-up roller 4 to rotate. The take-up roller 4 drives the decorative paper roll body 5 to perform conveying and winding operations through friction. When the tension of the decorative paper roll body 5 changes, the auxiliary sub-rollers 402 on both sides of the main roller 401 will rotate accordingly to adapt to the change in the roll body 5, depending on whether it is being wound or unwound. At the same time, the tension springs 405 connected to the extension rods 404 on both sides of the lower end of the main roller 401 play a buffering and adjusting role. When the tension of unidirectional conveying increases, the tension springs 405 are stretched to absorb part of the tension; when the tension decreases, the tension springs 405 contract, causing the main roller 401 to return to the appropriate position, thereby ensuring the winding... The material tension is relatively stable, while the fan-shaped contact plate 410 transmits the extrusion pressure to the rubber bearing block 409 through the hinged movable short plate 408 below. At this time, deformation will occur, which will achieve the effect of assisting in adjusting the tension of the roll material. The electric telescopic rod 415 controls the U-shaped lifting plate 413 to slide in the guide groove 412, thereby driving the upper extrusion roller 414 to move up and down. The lower extrusion roller 419 is installed on the movable inner support plate 418. The pressure spring 417 and damper under the movable inner support plate 418 can buffer the changes in the tension of the roll material. The upper extrusion roller 414 and the lower extrusion roller 419 cooperate with each other to apply a certain pressure to the roll material, further adjusting the tension of the roll material and preventing the roll material from being excessively loose or stretched.

[0032] according to Figure 6The bidirectional cylinder 205 pushes the connecting block 204, which in turn drives the connecting rod 202 to slide within the guide slot 201. The arc-shaped actuating plate 203 at the lower end of the connecting rod 202 moves accordingly, actuating and adjusting the decorative paper roll body 5 to keep the roll in the center of the conveying mechanism and prevent the roll from shifting during the conveying process.

[0033] The above is the entire working process of the device, and all contents not described in detail in this specification are existing technologies known to those skilled in the art.

[0034] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
