The roller assembly comprises an axle frame and a plurality of rollers, the plurality of rollers are rotatably arranged on the axle frame, the axle frame is installed on the frame body and can be translated left and right, and the frame body is eccentrically arranged with a paper inlet of an external suction unit.

[0005] As a further improvement of the utility model, the upper side of the front and rear two side edges of the frame body is provided with a sliding rail, the lower side of the front and rear two side edges of the axle frame is fixedly provided with a sliding block, and the sliding block is slidably arranged on the sliding rail, so as to install the axle frame on the frame body and can be translated left and right.

[0006] As a further improvement of the utility model, the axle frame comprises three vertical rods and two horizontal rods, the three vertical rods are arranged side by side, the rollers are arranged between the three vertical rods, the end part is rotatably installed on the side surface of the vertical rod, the two horizontal rods are arranged on the two ends of the three vertical rods respectively, so as to form a frame structure with the three vertical rods, the lower side of the middle part of the vertical rod is fixedly provided with a translation plate, the middle part of the frame body is rotatably provided with a driving lead screw, and the driving lead screw penetrates through the translation plate and is threadedly connected with the translation plate.

[0007] As further improvement of the utility model, the upper portion of the shaft support is provided with a left paper blocking plate and a right paper blocking plate, and the left paper blocking plate and the right paper blocking plate can slide on the shaft support in opposite directions or in opposite directions.

[0008] The utility model discloses the beneficial effect: compared with the existing paper dragging frame in the background art, the existing paper dragging frame roller and frame body are fixed, cannot move left and right, when conveying different size corrugated paper, manual placement small size corrugated paper is difficult to be in position.But the shaft support in the utility model can move left and right and is installed on the frame body, and the frame body and the paper inlet of the external air suction unit are arranged in an eccentric mode, so that the side edge of one side of the frame body is as close to the center position of conveying as possible, when conveying small size paper, the shaft support and the frame body coincide in the height direction, and a person can stand to the side edge of the frame body, which further facilitates the person to place the paper on the roller, the upper portion of the shaft support is provided with left and right paper blocking plates that can slide in opposite directions or in opposite directions, and the left and right paper blocking plates can be adjusted in position to adapt to different size corrugated paper, so that the person does not need to manually and accurately place the corrugated paper to the center position of the frame body every time, the operation is more convenient, and the efficiency and accuracy of the corrugated paper conveying are improved. BRIEF DESCRIPTION OF DRAWINGS

[0009] Figure 1 It is the overall structural drawing of the paper dragging frame of the utility model;

[0010] Figure 2 It is the overall structural drawing of the roller assembly. DETAILED DESCRIPTION

[0011] The utility model will be further described in connection with the embodiments given in the drawings.

[0012] Referring to Figure 1 The paper dragging frame of the embodiment includes a frame body 1 and a roller assembly 2 arranged on the frame body 1. The roller assembly 2 includes a shaft support 21 and a plurality of rollers 22, and the plurality of rollers 22 are rotatably arranged on the shaft support 21. The shaft support 21 is movably installed on the frame body 1, and the frame body 1 is arranged eccentrically with the paper inlet of the external air suction unit. Compared with the background art in which the rollers are fixed with the frame body and it is difficult to place small size corrugated paper in position, the frame body 1 of the embodiment is arranged eccentrically with the paper inlet of the external air suction unit, so that the side edge of one side of the frame body 1 is as close to the center position of conveying as possible. When conveying small size paper, the shaft support 21 and the frame body 1 coincide in the height direction, and a person can stand to the side edge of the frame body 1, which further facilitates the person to place the paper on the rollers 22. As for large paper, the eccentric position can be moved to a flat position through the moving mode of the shaft support 21, so as to avoid the influence on the large paper caused by the eccentricity.

[0013] Further, referring to Figure 1As shown, the upper side of the front and rear side edges of the frame body 1 is provided with a sliding rail 11, and the lower side of the front and rear side edges of the shaft frame 21 is fixedly provided with a sliding block 23, which is slidably arranged on the sliding rail 11, so that the shaft frame 21 is transversely installed on the frame body 1. Through the cooperation of the sliding rail 11 and the sliding block 23, the shaft frame 21 can transversely move more smoothly on the frame body 1. Compared with the background art, the shaft frame 21 can be adjusted according to the size of the paper, and better adapt to the conveying of paper of different sizes.

[0014] Further, referring to Figure 2 As shown, the shaft frame 21 comprises three vertical rods 211 and two horizontal rods 212. The three vertical rods 211 are arranged side by side, and the roller 22 is arranged between the three vertical rods 211 and rotatably installed on the side surface of the vertical rod 211. The two horizontal rods 212 are arranged at the two ends of the three vertical rods 211, respectively, to form a frame structure with the three vertical rods 211. The lower side of the middle part of the middle vertical rod 211 is fixedly provided with a translation plate 213, and the middle part of the frame body 1 is rotatably provided with a driving lead screw 12. The driving lead screw 12 penetrates through the translation plate 213 and is threadedly connected with the translation plate 213. The structure of the shaft frame 21 is a frame structure, and the driving lead screw 12 is threadedly connected with the translation plate 213, so that the transverse movement of the shaft frame 21 can be more accurately controlled, thereby better adapting to the conveying of paper of different sizes and solving the problem that the roller cannot be adapted to the conveying of paper of different sizes in the background art.

[0015] Further, the upper side of the shaft frame 21 is provided with a left paper stop plate 214 and a right paper stop plate 215, which can slide relative to or away from each other on the shaft frame 21. The left and right paper stop plates are adjustably arranged to assist manual adjustment of the position of the paper. In the embodiment, one of the left paper stop plate 214 and the right paper stop plate 215 is driven by a lead screw, and the other is manually driven. Workers can adjust the relative positions of the left paper stop plate 214 and the right paper stop plate 215 by standing on one side, thereby adjusting the position of the corrugated paper.

[0016] In summary, the paper frame effectively solves the problem of difficult placement of small-size corrugated paper in the background art through the eccentric arrangement of the frame body 1 and the paper inlet of the external air suction unit, the transverse movement of the shaft frame 21, the reasonable structure design of the shaft frame 21, and the adjustable paper stop plate.
