[0019] The following is a further detailed description of the present application in combination with the attached Figures 1-3 to the present application.

[0020] The embodiment of the present application discloses a packing mechanism for books. Refer to Figures 1-3, A packing mechanism for books and periodicals, including a strapping machine 1 and a driving component 2. The driving component 2 is installed on the side of the strapping machine 1. A rotating groove is provided on the surface of the working table of the strapping machine 1. The tape inserting port on the strapping machine 1 is located at the center of the rotating groove. A reversing disk 3 is installed in the rotating groove. The reversing disk 3 makes a circular motion in the rotating groove. The reversing disk 3 includes four sector trays 301 distributed in a circular pattern in the rotating groove. A gap is reserved between two adjacent sector trays 301. The width of the gap is the same as the width of the tape inserting port. An engaging and guiding structure is provided between the sector tray 301 and the inner wall of the rotating groove. The sector tray 301 is guided through the engaging and guiding structure to limit the deflection of the sector tray 301, so that it makes a circular motion with the symmetry center as the center. A telescopic connection unit 303 is installed between two adjacent sector trays 301. The connection and separation of the two sector trays 301 are realized through the expansion and contraction of the telescopic connection unit 303. When connected, the four sector trays 301 are spliced to form a synchronous rotating whole. When one of the sector trays 301 is driven to rotate by the driving component 2, the whole reversing disk 3 can be rotated. When separated, the gap is aligned with the tape inserting port, which is convenient for the strapping machine to strap.

[0021] Refer to Figures 1-3 , The engaging and guiding structure can be selected as an annular guide rail slider or an annular guide groove slider structure according to needs. An annular T-shaped groove can be provided at the bottom or side wall of the rotating groove. A number of T-shaped sliders adapted to the T-shaped groove are installed on the sector tray 301 to limit the deflection of the sector tray 301, so that it makes a circular motion with the symmetry center as the center.

[0022] Refer to Figures 2-3 , A cavity is provided on the sector tray 301. A number of telescopic connection units 303 are installed in both of the two opposite cavities. The telescopic connection unit 303 includes a block 3031 slidably installed in the cavity. A socket adapted to the block 3031 is provided on the sector tray 301.

[0023] Refer to Figures 2-3, the driving block 3031 can be selected as an electric telescopic rod or an electromagnetic adsorption structure according to needs to control its movement to complete telescopic insertion. In the embodiment of the present application, in order to ensure rapid response, an electromagnetic adsorption structure is selected. A spring 3032 is installed between the block 3031 and the side wall of the cavity. An expansion rod 3033 is movably installed inside the spring 3032. Both ends of the expansion rod 3033 are fixedly connected to the sector tray 301 and the block 3031 respectively, realizing the movement guidance of the block 3031 and ensuring the accuracy of the docking of the block 3031. Electromagnets 302 are installed in the cavities of the remaining two sector trays 301. The block 3031 is adsorbed by the electromagnetic force of the electromagnets 302, so that the block 3031 passes through the socket and fits with the electromagnet 302. Since the sector tray 301 is selected to make a circular motion and the block 3031 is vertically inserted, the block 3031 will be clamped with the side wall of the socket, and the synchronous rotation of the sector tray 301 can be completed.

[0024] Refer to Figure 2 , the driving assembly 2 includes a driving motor 201 installed on the bundling machine 1. The driving motor 201 is connected with a reducer through a coupling. The reducer and the sector tray 301 are connected through a transmission component. The transmission component includes two reversing driving units 203 installed on the bundling machine 1. The reversing driving unit 203 includes a rotating shaft 2031 rotatably installed on the bundling machine 1. A transmission unit 202 is installed between the rotating shaft 2031 and the output shaft of the reducer. A gear 2032 is installed on the rotating shaft 2031. Tooth grooves are formed on the arc surface of the sector tray 301. By meshing with one of the gears 2032 through the tooth grooves, through the relay transmission of the two gears 2032, the gears 2032 can ignore the gap between the sector trays 301, ensuring that the sector tray 301 can be continuously driven to rotate more than ninety degrees. The transmission unit 202 adopts a chain transmission unit. The driving motor 201 runs forward and backward. After rotating forward ninety degrees once, it must rotate backward ninety degrees the next time, and then rotate forward ninety degrees the next time, and so on in a cycle, preventing the power supply wire from interfering with the binding tape due to the rotation of the electromagnet 302 exceeding the binding opening of the bundling machine 1.

[0025] The implementation principle of a book packaging mechanism in the embodiment of the present application is as follows:

[0026] When the bundling machine is in the standby state, the four sector trays 301 are kept connected through the telescopic connection unit 303 to form a whole. At this time, the two gaps between the sector trays 301 are aligned with the tape insertion port of the bundling machine. The electromagnet 302 is energized, and the telescopic connection unit 303 is in the extended state to ensure the tight connection between the sector trays 301.

[0027] The books and periodicals are fed to the central positions of the four sector trays 301. When bundling is required, the electromagnet 302 is powered off, and the telescopic connection unit 303 retracts under the action of the spring 3032, resulting in the disconnection of the connection between the sector trays 301, forming a gap. The width of the gap is the same as the width of the tape insertion port.

[0028] At this time, the bundling tape of the bundling machine can pass through the gap from the tape insertion port to bundle the books and periodicals.

[0029] After one bundling is completed, the energized electromagnet 302 attracts the clamping block 3031 in the telescopic connection unit 303, so that the clamping block 3031 slides along the cavity under the action of the spring 3032 and passes through the socket on the sector tray 301 to fit with the electromagnet 302.

[0030] During the rotation of the sector tray 301, the vertical insertion of the clamping block 3031 will cause it to be clamped with the side wall of the socket, thereby realizing the synchronous rotation between the sector trays 301.

[0031] The driving motor 201 drives the gear 2032 on the rotating shaft 2031 and the sector tray 301 to rotate through the transmission unit 202. Since there are two reversing drive units 203 respectively installed on both sides of the bundling machine, through the relay transmission of the two gears 2032, the gap between the sector trays 301 can be ignored, and it can be continuously driven to rotate by 90 degrees. Then, the electromagnet 302 and the driving motor 201 are powered off, and the bundling machine 1 performs bundling. After the bundling tape completes the cross bundling, the bundled books and periodicals are unloaded, and the unbundled books and periodicals are loaded to prepare for the next round of bundling operation.
