Detailed Implementation

[0016] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.

[0017] The following is combined Figures 1 to 4 The embodiments of this utility model are described below.

[0018] This embodiment relates to an adjustable page feeding structure, including a frame, a conveyor belt 101, a front roller 201, an end roller 202, a drive roller 203, and a length adjustment mechanism. The front roller 201 is rotatably connected to the frame, the end roller 202 is rotatably connected to the length adjustment mechanism, and the drive roller 203 is rotatably connected to the frame. The drive roller 203 is used to drive the conveyor belt 101 to move. The length adjustment mechanism is movably connected to the frame. The front roller 201 and the end roller 202 are used to support the conveyor belt 101. The conveyor belt 101 includes a feeding section and a delivery end. The length adjustment mechanism allows the position of the delivery end to be adjusted along the conveying direction.

[0019] The front roller 201 and the end roller 202 mounted on the frame form a conveying plane for the conveyor belt 101. The drive roller 203 is connected to the motor to provide power to the conveyor belt 101. The end roller 202 can adjust its length along the direction of the conveyor belt 101 and change the position of the delivery end, so that the delivery end of the conveyor belt 101 can be quickly adjusted when different sizes of pages need to be delivered during the production process.

[0020] In some embodiments, the length adjustment mechanism includes an adjustable block 304, a support roller 204, a lateral adjustment component, a positioning component, and an adjustable roller 205. The support roller 204 is rotatably connected to the frame. The adjustable block 304 is connected to the frame via the lateral adjustment component, which allows the position of the adjustable block 304 to be locked at different positions along the conveying direction of the conveyor belt 101. The end roller 202 is rotatably mounted on the adjustable block 304. The adjustable roller 205 is connected to the frame via the positioning component, which allows the position of the adjustable roller 205 to be adjusted along with the end roller 202.

[0021] When the position of the feed end needs to be adjusted, the position of the adjustable block 304 is changed by the lateral adjustment component. Since the end roller 202 is set on the adjustable block 304, the feed end position determined by the end roller 202 also changes accordingly, thus realizing the adjustment of the feed end position. The support roller 204 and the end roller 202 support the conveyor belt 101. The adjustment component allows the position of the adjustable roller 205 to be adjusted with the end roller 202, ensuring that the conveyor belt 101 maintains appropriate tension even after the feed end position is changed. In this way, the feed end position is easily adjusted by using the adjustable block 304, support roller 204, lateral adjustment component, adjustment component, and adjustable roller 205, while maintaining appropriate tension on the conveyor belt 101, preventing excessive tension and ensuring the service life of the conveyor belt 101.

[0022] Furthermore, the horizontal adjustment assembly includes an adjustment shaft 301, a transmission gear, and a gear rack 305. The adjustment shaft 301 is rotatably connected to the frame and is drivenly connected to the transmission gear. The gear rack 305 is slidably connected to the frame and slides along the conveying direction of the conveyor belt 101. The gear rack 305 is fixedly connected to the adjustable block 304, and the transmission gear meshes with the gear rack 305.

[0023] When the adjusting shaft 301 rotates, it drives the transmission gear. Through the meshing of the transmission gear and the gear rack 305, the gear rack 305 moves linearly, causing the adjustable block 304 to move the position of the end roller 202 along the sliding direction of the gear rack 305, thus achieving position adjustment of the end roller 202. This structure has the advantages of convenient arrangement and high adjustment accuracy. It is understood that the adjusting shaft 301 can be driven by a drive motor or manually rotated. In this embodiment, the sliding of the gear rack 305 along the conveyor belt 101 is achieved by the fixed block 302. The fixed block 302 is slidably connected to the adjustable block 304, guiding the adjustable block 304 and restricting its sliding only to the guide groove on the fixed block 302.

[0024] In addition to the above-mentioned technical solution including adjusting shaft 301, transmission gear, and gear rack 305, the horizontal adjustment assembly can also adopt conventional solutions in the field, such as using a cylinder, hydraulic cylinder, or electric push rod to directly drive the adjustable block 304 to move.

[0025] Furthermore, the adjusting assembly includes a base block 303 and a locking pin. A locking hole is provided on the frame, and an adjusting groove is provided on the base block 303. The adjusting groove extends along the conveying direction of the conveyor belt 101 and passes through the base block 303 towards the frame. The locking pin passes through the adjusting groove and is threadedly connected to the locking hole. The adjustable roller 205 is rotatably mounted on the base block 303. The locking pin, passing through the adjusting groove and threadedly connected to the locking hole, locks the base block 303 onto the frame, thereby allowing the adjustable roller 205 to be mounted on the frame via the base block 303. By loosening the locking pin, the position of the base block 303 can be released, and the base block 303 can be moved to different positions to change the position of the adjustable roller 205. This allows for adjustment of the position of the adjustable roller 205 to adapt to end-point position adjustments, maintaining appropriate tension on the conveyor belt 101. This method of adjustment makes the position adjustment of the adjustable roller 205 simple.

[0026] In other embodiments, the length adjustment mechanism may employ different implementation methods. For example, the length adjustment mechanism may include a slide and a linear drive mechanism, wherein the linear drive mechanism drives the slide to move along the conveying direction of the conveyor belt 101, and the frame is mounted on the slide. Thus, by moving the frame and the entire conveyor belt 101 along the conveying direction via the linear drive mechanism, the position of the delivery end can be adjusted.

[0027] The conveyor belt 101 is a suction belt. The suction belt makes the transport of book pages more reliable.

[0028] The adjustable page feeding structure also includes a negative pressure box 401, which is fixedly connected to the frame and located between the front roller 201 and the end roller 202. The conveyor belt 101 obtains suction through the negative pressure box 401, which is connected to a vacuum pump.

[0029] The negative pressure box 401 is equipped with a suction belt conveyor belt 101 to provide negative pressure, providing a simple solution for the negative pressure environment component of the suction belt. Specifically, the conveyor belt 101 is provided with several suction holes on its surface, and the suction hole array is arranged on the surface of the conveyor belt 101 and directly opposite the location of the negative pressure box 401. Thus, when the air pump is started, suction is generated on the surface of the conveyor belt 101 through the negative pressure box 401 and the suction holes, enabling the conveyor belt 101 to stably transport book pages at a higher speed.

[0030] The adjustable page delivery structure also includes a detector 500, which is used to detect when a page leaves the conveyor belt 101.

[0031] This embodiment also provides a book page mounting line, including the adjustable book page feeding structure mentioned above. This book page mounting line can quickly adjust the position of the feed end of the conveyor belt 101 to quickly adapt to paper pages of different sizes.

[0032] The page mounting line also includes a page mounting groove, the width of which is adjustable to accommodate pages of different sizes.
