Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of glue binding machine, concretely is a kind of transverse positioning mechanism of glue binding machine paper. BACKGROUND

[0002] In the operation process of glue binding machine, the accurate transverse positioning of paper is the key link to ensure the binding quality. At present, the common transverse positioning mechanism of glue binding machine paper mostly adopts the mode that air cylinder drives movable plate to realize positioning. Specifically, through the extension and retraction movement of air cylinder, movable plate is driven to move, and then the end of movable plate is pressed against paper, paper is pushed to move towards fixed part, so as to achieve the positioning operation of paper. The typical existing structure is disclosed in the precise positioning mechanism of cover paper of glue binding machine in application No. CN2023223851741.

[0003] However, this traditional positioning mode has obvious limitations. When the precision of air cylinder is insufficient, or due to other factors interference, movable plate can move excessively towards fixed part. In this case, excessive pressure can press paper to arch state, and after losing pressure, paper will rebound to restore original state, which will cause paper to lose positioning and have to be repositioned. This not only reduces the working efficiency of glue binding machine, but also can cause damage to paper due to multiple positioning, which affects the final binding effect.

[0004] In view of the above problems existing in the prior art, a new transverse positioning mechanism of glue binding machine paper is urgently needed to overcome the defects of traditional mode and improve the accuracy and stability of paper positioning. INVENTION CONTENTS

[0035] The driving device is drivingly connected with the conveying belt, for driving the conveying belt to move towards or away from the fixed part, so that the paper placed on the bearing plane follows the conveying belt to move towards or away from the fixed part;

[0036] The paper pressing mechanism 5 is arranged above the bearing plane, for pressing the paper above the bearing plane towards the bearing plane, to increase the frictional pressure between the paper and the bearing plane.

[0037] In the above technical solution, the rack and the clamping surface table form a support and working platform, and the fixed part on the clamping surface table provides a reference point for paper positioning. The conveying belt is distributed on both sides of the clamping surface table, and its bearing plane is used for bearing and conveying paper. The driving device is connected with the conveying belt, and by driving the movement of the conveying belt, the paper is driven to approach or move away from the fixed part. The paper pressing mechanism is located above the bearing plane, to increase the frictional pressure between the paper and the bearing plane, and to ensure the stability of the paper during conveying.

[0038] The overall architecture design realizes the transverse positioning function of paper. Compared with the traditional cylinder positioning mode, the conveying belt and the fixed part are used for positioning, which avoids the arching of paper due to excessive extrusion, and improves the positioning accuracy. The paper pressing mechanism enhances the conveying stability, reduces the shaking, deviation and sliding of paper during conveying, and ensures the smooth progress of positioning and binding process.

[0039] Specifically, the driving device comprises a driving motor 7, a rotating shaft 8 and pulleys 9 on both ends of the rotating shaft 8, the driving motor is drivingly connected with the rotating shaft for driving the rotating shaft to rotate, the pulleys are fixed on both ends of the rotating shaft, and the conveying belt is drivingly connected with the pulleys.

[0040] In the embodiment, the driving device adopts the driving motor as a power source, the motor drives the rotating shaft to rotate, and the pulleys on both ends of the rotating shaft rotate in turn, thereby driving the conveying belt connected therewith to rotate. The stable and reliable power provided for the conveying belt makes the paper conveying process more stable and uniform in speed, which is beneficial to improving the positioning precision of the paper and ensuring the stability of the whole positioning mechanism, thereby reducing the positioning deviation caused by unstable power.

Meanwhile, the transmission mode has simple structure and is convenient to maintain, thereby reducing the maintenance cost of the equipment and further improving the reliability of the positioning mechanism. Of course, gears or belt pulleys that mesh with each other can also be used for transmission.

[0043] Specifically, a rotating shaft mounting plate 12 is fixed on the rack, and the rotating shaft is rotatably connected with the rotating shaft mounting plate through a bearing.

[0044] In the embodiment, the rotating shaft mounting plate fixed on the rack is rotatably connected with the rotating shaft through the bearing.

[0047] In the embodiment, the pressing plate of the paper pressing mechanism is composed of a mounting part and a paper pressing plate, the mounting part is fixedly connected with the rack to ensure the position of the pressing plate. The steel ball hole is provided on the paper pressing plate, the steel ball in the hole can move along the axial direction, and the radial limiting structure at the two ends of the steel ball hole prevents the steel ball from falling off. The design of the steel ball increases the frictional pressure between the paper and the bearing plane, and meanwhile, the axial movement and the limiting structure of the steel ball ensure that the paper pressing mechanism can press the paper with appropriate pressure and avoid pressing the paper to death.

[0048] Specifically, the distance between the paper pressing plate and the bearing plane is 2-8 mm.

[0049] In the embodiment, the appropriate distance setting enables the paper pressing mechanism to adapt to the conveying and positioning of paper with various thicknesses, enhances the versatility of the positioning mechanism, and maximizes the protection of the paper from damage under the premise of ensuring the stability of conveying, thereby improving the adaptability of the perfect binding machine to different paper.

[0050] Specifically, the axial displacement distance of the steel ball is 0.1-2 mm.

[0051] In the embodiment, the appropriate displacement distance of the steel ball improves the adaptability of the paper pressing mechanism to complex situations in the paper conveying process, further ensures the stability of the paper conveying, reduces the positioning deviation caused by uneven thickness or conveying jitter of the paper, and improves the accuracy and reliability of the overall positioning.

[0052] Specifically, the steel ball hole is two, which are arranged at intervals along the length direction of the paper pressing plate.

[0053] In the embodiment, the two steel ball holes arranged at intervals enhance the uniformity of the pressure of the paper pressing mechanism on the paper, further improve the stability of the paper conveying, and especially for the paper with large size or irregular shape, the flatness of the paper in the conveying and positioning process can be better ensured, and the positioning precision is improved.
