[0027] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0028] Reference Figure 1-4 The utility model provides a front and rear pressure rod device for a printer material: it includes a support block 1, two support blocks 1, the two support blocks 1 are arranged opposite to each other, an adjusting rod 2 is rotatably connected between the opposite sides of the two support blocks 1, a plurality of mounting seats 3 are provided on the adjusting rod 2, a plurality of mounting seats 3 are arranged in a linear array, a plurality of mounting seats 3 are fixedly sleeved on the outer surface of the adjusting rod 2, an adjusting plate 4 is provided on the top of the plurality of mounting seats 3, a clamping assembly is provided on the adjusting plate 4, a front pressure rod 5 is provided on one side of the adjusting rod 2, a movable plate 6 is provided on the other side of the front pressure rod 5, a rear pressure rod 7 is provided on one side of the movable plate 6, and a limiting column 8 is rotatably connected to the rear pressure rod 7. The setting of the positioning column 8, after it is installed on the printer housing, can make the rear pressure rod 7 rotate with the limiting column 8 as the axis. Through the coordinated use of structures such as the support block 1, the adjusting rod 2, the mounting seat 3, the adjusting plate 4, the movable plate 6, the limiting column 8 and the connecting piece 10, after manually pressing the front pressure rod 5 or the rear pressure rod 7, the clamping roller 12 can be rotated and lifted upward from the front or rear of the device respectively, so that the material to be printed can pass from under the clamping roller 12, avoiding the problem that the traditional clamping device only has a one-way pressure rod, so that when loading materials such as film and paper, two people are required to complete the loading of film, paper and other materials, which is not only inconvenient but also reduces the loading efficiency.

[0029] The front pressure rod 5 is L-shaped, and the front pressure rod 5 and the movable plate 6 are hinged to each other. The rear pressure rod 7 is Z-shaped, and the rear pressure rod 7 and the movable plate 6 are hinged to each other. By setting the front pressure rod 5 and the rear pressure rod 7 in different shapes, the front pressure rod 5 and the rear pressure rod 7 can be installed on the printer without obstructing the use of other parts. In addition, the front and rear linkage rods are adopted, so that workers can operate the corresponding front pressure rod 5 or rear pressure rod 7 respectively when they are located in front and behind the printer. One side of the adjusting rod 2 is fixedly connected to the rotating block 9, and the other side of the rotating block 9 is fixedly connected to the front pressure rod 5.

[0030] The clamping assembly includes several connecting parts 10, and the several connecting parts 10 are fixedly connected to the bottom of the adjustment plate 4. The several connecting parts 10 are arranged in a linear array. A connecting block 11 is provided on the several connecting parts 10, and a clamping roller 12 is provided on the connecting block 11. The clamping roller 12 is rotatably connected to the connecting block 11. Through the setting of the clamping assembly, the printed material can be fixed and limited during the use of the printer to prevent the material from shifting during the transportation process.

[0031] Working principle: When in use, the device is installed on the printer through the two supporting blocks 1, and after the limiting column 8 is rotatably connected to the shell on one side of the printer, it can be used in conjunction with the conveyor belt or curved guide plate on the printer. During the use of the device, when it is necessary to pass the film or paper material to be printed from under the multiple pressure rollers 12, the front pressure rod 5 is manually pressed to rotate it, and the front pressure rod 5 drives the rotating block 9 and the adjusting rod 2 to rotate synchronously. The rotating adjusting rod 2 drives the corresponding mounting seat 3, the adjusting plate 4 and the multiple connecting parts 10 to rotate synchronously. After the connecting part 10 drives the corresponding connecting block 11 and the pressure roller 12 to rotate synchronously, the pressure roller 12 can be rotated upward to keep the pressure roller 12 away from the conveyor belt or the curved guide plate, so that the film or paper material can pass from under the lifted pressure roller 12.

[0032] When the film or paper material to be printed passes through the side of the pressure roller 12, the worker walks to the back of the printer and manually presses the rear pressure rod 7. Under the action of the limit column 8, the rear pressure rod 7 rotates with the limit column 8 as the axis, and pulls the movable plate 6 hinged to it to move toward the side close to the rear pressure rod 7. The movable plate 6 drives the front pressure rod 5 hinged to it to move synchronously. Under the cooperation of the support block 1 and the adjusting rod 2, the front pressure rod 5 rotates with the rotating block 9 as the axis, and in the process of rotation, drives the rotating block 9, the adjusting rod 2, the mounting seat 3, the adjusting plate 4, the connecting block 11 and the pressure roller 12 and other structures to rotate again, and the pressure roller 12 can be lifted up again, which makes it convenient for workers to perform material pressing and loosening operations in front and behind the printer.

[0033] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent replacements for some of the technical features therein. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
