[0019] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.
[0020] according to Figure 1-3 This utility model provides a roller centering adjustment mechanism, including: a fixed frame 1, a movable frame 2, and a support base 3.
[0021] The support base 3 is provided with a support block 32; the fixed frame 1 and the movable frame 2 are respectively arranged on both sides of the support base 3; one end of the roller is rotatably connected to the fixed frame 1, and the other end is rotatably connected to the support block 32; the movable frame 2 includes: a gear 21, a connecting rod 22, and a handwheel 23; the connecting rod 22 is rotatably arranged inside the movable frame 2; one end of the connecting rod 22 is connected to the gear 21, and the other end is connected to the handwheel 23; the support base 3 is provided with a rack 31; the rack 31 can move on the support base 3; the rack 31 meshes with the gear 21; the support block 32 is connected to the rack 31.
[0022] When adjusting the roller angle, first install both ends of the roller on the fixed frame 1 and the support block 32 respectively. Then, rotate the handwheel 23 of the moving frame 2, causing the connecting rod 22 to rotate, which in turn causes the gear 21 to rotate. The rotation of the gear drives the rack 31 to move, which in turn moves the support block 32. This causes the roller end at the support block 32 to move accordingly, while the roller at the fixed frame 1 rotates at a certain angle relative to the fixed frame 1. When the roller at the support block 32 rotates to a certain position, it aligns with the relevant structure, thus completing the roller angle adjustment. In other words, this invention sets the rollers on the fixed frame 1 and the support block 32 respectively, and the support block 32 meshes with the gear 21 of the moving frame 2 via the rack 31. Rotating the handwheel 23 adjusts the position of the support block 32, correspondingly adjusting the roller angle. This makes it difficult for the roller to deviate during operation and is convenient to use.
[0023] The fixed frame 1 has a groove 11; a slider 12 is provided in the groove 11. The slider 12 can slide in the groove 11; one end of the roller is rotatably connected to the slider 12. The movable frame 2 includes a rotating cavity 24; a connecting rod 22 is rotatably disposed in the rotating cavity 24. The movable frame 2 also includes a fixing structure 25; the fixing structure 25 includes a pressure rod 251 and a control handle 252; the movable frame 2 has a threaded groove 26; the pressure rod 251 has a thread; one end of the pressure rod 251 is connected to the control handle 252, and the other end is screwed into the rotating cavity 24. The pressure rod 251 extends into the rotating cavity 24; the pressure rod 251 can move away from or closer to the rotating cavity 24 so that the pressure rod 251 can press against the connecting rod 22. The connecting rod 22 has a pressure groove 221; the pressure rod 251 can move away from or closer to the pressure groove 221 so that the pressure rod 251 presses against the connecting rod 22.
[0024] When the roller rotates, its projection along the line connecting the movable frame 2 and the fixed frame 1 changes, requiring a change in the distance between the movable frame 2 and the fixed frame 1 to accommodate the roller. This invention features a groove 11 on the fixed frame 1, within which a slider 12 is slidably mounted. One end of the roller is rotatably mounted on the slider 12. This allows the roller to rotate relative to the slider 12, which in turn moves the slider 12. When the movable frame 2 moves the roller, the slider 12 is moved to match the movable frame 2, eliminating the need to change the distance between the movable frame 2 and the fixed frame 1. The slider 12 automatically adjusts according to the actual situation, making roller adjustment more convenient and faster. A material such as PTFE can be placed between the slider 12 and the side wall of the groove 11 to prevent the slider 12 from sliding automatically and causing the roller to deviate. The movable frame 2 can then move the roller, which in turn moves the slider 12 accordingly. The movable frame 2 has a rotating cavity 24, in which the connecting rod 22 rotates. When the handwheel drives the connecting rod 22, and the connecting rod 22 drives the gear 21 to rotate to a certain extent, the gear 21 needs to be fixed to prevent accidental rotation of the gear 21 from causing a change in the position of the roller. When it is necessary to fix the gear 21, the control handle 252 can be rotated so that the pressure rod 251 is screwed into the screw groove 26 and extends into the rotating cavity 24. Then the connecting rod 22 is pressed down, making it difficult for the connecting rod 22 to rotate. Thus, the gear 21 is difficult to rotate and is fixed. When the gear 21 is fixed, the rack 31 is also difficult to move, that is, the support block 32 will be fixed, making it difficult for the roller to move. A groove 221 is also provided on the connecting rod 22. When the pressure rod 251 presses down on the connecting rod 22, it is pressed into the groove 221 to fix the connecting rod 22. When the pressure rod 251 presses the connecting rod 22 tightly, pressure is applied to the connecting rod 22. After the device has been used for a long time, indentations are easily formed on the connecting rod 22, causing deformation of the side wall of the connecting rod 22. This may cause protrusions to appear near the indentations of the connecting rod 22. When the connecting rod 22 needs to be removed later, these protrusions are likely to abut against the side wall of the rotating cavity 24, making it difficult to pull out the connecting rod 22. This utility model sets a groove 221, and the pressure rod 251 presses down on the groove 221, so that the indentations and protrusions caused by deformation will appear in the groove 221. Even if protrusions are formed, these protrusions are unlikely to interfere with the inner wall of the rotating cavity 24, making it easier to remove and put in the connecting rod 22.
[0025] Working principle and usage process of this utility model:
[0026] When the roller needs adjustment, one end of the roller is rotatably mounted on the support block 32, and the other end is rotatably connected to the slider 12. Then, the handwheel 23 is turned to make the connecting rod 22 rotate, which in turn drives the gear 21 to rotate. When the gear 21 rotates, the rack 31 meshing with it will move, thereby moving the support block 32. This causes the roller on the support block 32 to move and rotate. When the roller moves and rotates, the roller at the slider 12 also rotates relative to the slider 12, and the slider 12 moves accordingly. When the roller moves to a certain position, it can be aligned with the relevant structure. At this time, the control handle 252 is turned to make the pressure rod 251 screwed into the screw groove 26, so that the pressure rod 251 extends into the rotating cavity 24 and abuts against the surface of the pressure groove 221, thereby stopping the connecting rod 22 from rotating and fixing the gear 21, thus fixing the rack 31 and the support block 32, and limiting the roller.
[0027] In summary, this utility model, by setting the rollers on the fixed frame and the support block respectively, and the support block meshing with the gear of the movable frame through a rack and pinion, allows the position of the support block to be adjusted by turning the handwheel, and the angle of the roller can be adjusted accordingly. This makes it difficult for the roller to deviate during operation and is more convenient to use.

Those skilled in the art to which this utility model pertains may make various modifications or additions to the described specific embodiments or use similar methods to substitute them, without departing from the spirit of this utility model or exceeding the scope defined by the appended claims.
