[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model. The utility model is further described in combination with the drawings and embodiments:

[0022] like Figure 1 and Figure 2 As shown, an automatic book weighing device includes a base 11, a weighing device 12 is arranged on the base 11, a conveyor belt 1 is placed on the weighing device 12, a material discharge chute 13 is obliquely arranged at one end of the conveyor belt 1, a receiving platform 2 is arranged below the end of the material discharge chute 13, a driving box 25 and a plurality of groups of equally distributed fixed plates 21 are arranged on the receiving platform 2, a rotating shaft 22 is rotatably connected between a group of fixed plates 21, a roller 23 is arranged on the rotating shaft 22, a driving assembly connected to the plurality of rotating shafts 22 to realize synchronous and unidirectional movement of the plurality of rollers 23 is arranged in the driving box 25, and a qualified product conveyor belt 3 and a defective product conveyor belt 4 distributed opposite to the rollers 23 are respectively arranged on both sides of the receiving platform 2. Specifically, the driving assembly adopts a chain transmission method. The chain transmission belongs to the prior art and its principle is not described and the specific structure is not shown in the figure.

[0023] Further refinement of the embodiment of the present utility model is as follows: Figure 1 As shown, the roller 23 is at the same height as the conveying rollers of the qualified product conveyor belt 3 and the defective product conveyor belt 4, and the rotation speeds of the three are consistent; this arrangement can make the book transfer from the supporting platform to the qualified product conveyor belt 3 or the defective product conveyor belt 4 more stable.

[0024] It should be noted that the weighing device 12, the conveyor belt 1, the driving assembly, the qualified product conveyor belt 3 and the defective product conveyor belt 4 are all electrically connected to the controller, which is not shown in the figure.

[0025] The workflow of this utility model:

[0026] In the initial state, the controller controls the weighing device 12 to zero, and then places the book on the conveyor belt 1, and then the book can be automatically weighed. The weight range corresponding to the book is input into the controller in advance. If the measured weight value is obviously inconsistent with the set value and the error is large, the weighing device 12 feeds back a signal to the controller, and then the controller controls the driving component to work and then realizes the counterclockwise rotation of several rollers 23. At this time, the book is conveyed to the tail end of the conveyor belt 1 and then transferred to the supporting platform along the unloading chute 13. When the book falls on the roller 23 on the supporting platform, it can be automatically transferred to the defective conveyor belt 4, and then move with the defective conveyor belt 4 to the rework area for secondary production and processing. Similarly, if the weight value of the book is consistent with the set value range, several rollers rotate clockwise synchronously, and finally the book will move to the qualified conveyor belt 1, and finally be transported to the next process with the qualified conveyor belt 1 for packaging and boxing. The above process can be repeated to realize the weighing of books and timely remove books that do not meet the weight requirements and separate them and transfer them to different areas.

[0027] Compared with the prior art, the device can automatically transport unqualified books to the defective product conveyor belt 4 instead of simply collecting them after detecting unqualified books by weighing, so that unqualified books can be automatically transferred to the rework area for secondary production and processing, avoiding direct waste of the books. If the books are qualified by weighing, they will be transported to the next area for packaging, with accurate weighing and automatic sorting to remove defective books.

[0028] In some embodiments, Figure 1 and Figure 2 As shown, a rubber layer 24 is provided on the surface of the roller 23 ; this embodiment can reduce the probability of books being damaged by collisions when falling from the feed chute 13 to the roller 23 through the rubber layer 24 .

[0029] In other embodiments, Figure 1 As shown, a mounting frame 5 with an L-shaped main body is provided on the receiving platform 2, and a sensor 6, specifically a laser sensor, is provided on the mounting frame 5. The sensor 6 and the weighing device 12 are electrically connected to the controller; in this embodiment, after the laser sensor 6 detects that a book is transferred to the roller 23, a signal will be fed back to the controller, and then the controller controls the weighing device 12 to be immediately reset to zero, and then the weighing process of the next book can be started.
