[0029] The present invention is described in detail below with reference to the accompanying drawings.

[0030] like Figure 1-9 As shown, the multi-stage pressing and thermoforming equipment includes a frame and a feeding mechanism 10, a pressing mechanism 20, a thermoforming mechanism 30 and a discharging mechanism 40 arranged on the frame. The books to be processed pass through the feeding mechanism 10, the pressing mechanism 20, the thermoforming mechanism 30 and the discharging mechanism 40 in sequence. The feeding mechanism 10 is used to feed the books and adjust the position of the books for subsequent processing. The pressing mechanism 20 is used to press and clamp the upper part of the book. The thermoforming mechanism 30 is used to clamp and hot-press the lower part of the book and drive the book to move toward the discharging mechanism 40. The discharging mechanism 40 is used to deliver the formed books out of the frame. Before pressing the book, the operator first places the book flat on the feeding mechanism 10, and then the feeding mechanism 10 straightens and turns the book so that the book is placed vertically, and then the book is transferred to the pressing mechanism 20. The pressing mechanism 20 and the thermoforming mechanism 30 are located on the same production line. The pressing mechanism 20 is located above the thermoforming mechanism 30. The pressing mechanism 20 clamps and presses the upper end of the book, and the thermoforming mechanism 30 clamps and presses the lower end of the book. In this process, the pressing mechanism 20 and the thermoforming mechanism 30 clamp the book alternately. While clamping the book, the thermoforming mechanism 30 also drives the book to move toward the discharging mechanism 40. When the book reaches the discharging mechanism 40, the hot pressing and forming is completed, and then the discharging mechanism 40 sends the formed book away from the rack, thereby greatly saving the time cost required for processing and transportation, improving processing efficiency, and reducing production costs.

[0031] The feed mechanism 10 includes a book feeding module and a book vertical conversion module. The book feeding module includes a book feeding belt and a book feeding motor. The book feeding motor is connected to the book feeding belt and drives the book feeding belt toward the book vertical conversion module. The book vertical conversion module includes a flip loading head 11, which is used to convert books from a flat state to an upright state. The book feeding motor and the book feeding belt cooperate to transport the flat book to the flip loading head 11, which then flips the book from a flat state to a vertical state, thereby facilitating pressing and forming.

[0032] The pressing mechanism 20 includes a mounting plate 210 and a multi-station step pressing module. The multi-station step pressing module includes multiple pressure components, pressure drive components and force components. The pressure component is arranged on the mounting plate 210. The pressure component and the force component are arranged relative to each other. The pressure drive component is connected to the mounting plate 210 in a transmission manner. The pressure drive component drives the pressure component to move toward the force component to achieve the pressing of the book; the pressure component includes a pressing plate 211. The pressing plate 211 is arranged on the front side of the mounting plate 210 and the force component is arranged on the front side of the mounting plate 210. The assembly includes a top plate 220, a support head 221 and a support column 222. The support head 221 is fixedly arranged on the rear side of the top plate 220, and the front end of the support column 222 is fixedly connected to the support head 221; the pressure drive assembly includes a pressure drive motor 212, a pressure drive screw and a nut sleeve 213. The pressure drive motor 212 is transmission-connected to the pressure drive screw, and the pressure drive screw is screwed to one end of the nut sleeve 213. The rear side of the mounting plate 210 is fixedly connected to the other end of the nut sleeve 213. During lamination, the paper to be laminated moves between the pressure plate 211 and the top plate 220, and the pressure drive motor 212 drives the pressure drive screw to rotate, which in turn drives the nut sleeve 213 to rotate, and then drives the mounting plate 210 to move toward the top plate 220, and then presses the paper toward the top plate 220 through the pressure plate 211. The top plate 220, the support head 221 and the support column 222 bear the pressure of the pressure plate 211, thereby completing the lamination of the upper end of the paper. After lamination is completed, the pressure drive motor 212 drives the pressure drive screw to rotate, which in turn drives the nut sleeve 213 to rotate, and then drives the mounting plate 210 to move away from the top plate 220, thereby loosening the paper.

[0033] The support head 221 includes a connecting end, a force-bearing end, and a buffer spring 223. The connecting end and the force-bearing end are connected by a guide rod. One end of the buffer spring 223 abuts against the connecting end, and the other end of the buffer spring 223 abuts against the force-bearing end. The connecting end is fixedly connected to the rear side of the top plate 220. Because the connecting end is connected to the top plate 220, when the top plate 220 is subjected to force, the connecting end moves along the guide rod toward the force-bearing end, compressing the buffer spring 223 to buffer the pressure on the top plate 220, thereby increasing the service life of the top plate 220 and the support column 222.

[0034] The hot forming mechanism 30 includes a moving module and a hot pressing clamping module. The moving module includes a swing rod 370 and a support frame 371. The swing rod 370 is provided with a pivot hole 372. The support frame 371 is provided with a pivot portion 373. The pivot hole 372 is pivotally connected to the pivot portion 373. The swing rod 370 drives the support frame 371 to move along the swing direction of the swing rod 370. The hot pressing clamping module includes a first hot pressing component 310, a second hot pressing component 320 and a hot pressing drive component. The first hot pressing component 310 includes a first hot pressing plate 311 and a first bracket 312. The second hot pressing component 320 includes a first hot pressing plate 311 and a first bracket 312. The pressing assembly 320 includes a second hot pressing plate 321 and a second bracket 322. The first bracket 312 and the second bracket 322 are both arranged on the support frame 371 and are spaced apart. The first hot pressing plate 311 and the second hot pressing plate 321 are both provided with hot pressing surfaces. The hot pressing surface of the first hot pressing plate 311 and the hot pressing surface of the second hot pressing plate 321 are arranged facing each other. The first hot pressing plate 311 is arranged on the first bracket 312, and the second hot pressing plate 321 is arranged on the second bracket 322. The hot pressing drive assembly is used to drive the first bracket 312 and the second bracket 322 to move toward or away from each other. Before hot pressing the paper, the first hot pressing plate 311 and the second hot pressing plate 321 are first heated, and then the hot pressing driving component drives the first hot pressing plate 311 and the second hot pressing plate 321 to move toward each other, and the two hot pressing surfaces clamp and hot press the two sides of the paper, thereby further improving the hot pressing efficiency. When the hot pressing is completed, the hot pressing driving component drives the first bracket 312 and the second bracket 322 to move backwards, thereby facilitating the loosening of the clamping of the paper. At the same time, when the first hot pressing plate 311 and the second hot pressing plate 321 clamp the paper, the support frame 371 is in the initial position, and then the support frame 371 is driven to move to the next position by the rocker rod 370. At this time, the first hot pressing plate 311 and the second hot pressing plate 321 loosen the clamping of the paper, realizing the movement of the paper, greatly improving the transmission efficiency, reducing time cost and labor cost, and improving production efficiency.

[0035] The hot press drive assembly includes a hot press drive gear 331, a driven gear, a hot press drive screw 332, a first screw nut, and a second screw nut. The hot press drive gear 331 and the driven gear are arranged axially at the same level. The hot press drive screw 332 connects the hot press drive gear 331 and the driven gear respectively. The hot press drive screw 332 has two sections of oppositely directed threads of equal length. The first screw nut and the second screw nut are respectively sleeved on both ends of the hot press drive screw 332. The first bracket 312 is connected to the first screw nut, and the second bracket 322 is connected to the second screw nut. The hot press drive gear 331 transfers kinetic energy from the external transmission mechanism to the hot press drive screw 332. The driven gear then rotates in conjunction with the hot press drive screw 332, causing the hot press drive screw 332 to rotate the first and second screw nuts. The two oppositely directed threads on the hot press drive screw 332 cause the first and second screw nuts to move toward or away from each other, thereby driving the first hot press plate 311 and the second hot press plate 321 to move.

[0036] Both the first and second hot pressing assemblies 310 and 320 are equipped with a buffer member 340. The buffer member 340 includes a front buffer rod 341, a rear buffer rod 342, and a spring. The front end of the front buffer rod 341 is fixedly connected to the first hot pressing plate 311 or the second hot pressing plate 321. The front end of the rear buffer rod 342 is provided with a buffer groove, in which the spring is located. The rear end of the front buffer rod 341 is movably located in the buffer groove and abuts against the spring. The front buffer rod 341 pushes the first hot pressing plate 311 or the second hot pressing plate 321 to perform the hot pressing operation. When the first hot pressing plate 311 or the second hot pressing plate 321 contacts the paper, the paper exerts a reverse force on the first hot pressing plate 311 or the second hot pressing plate 321, causing the first hot pressing plate 311 or the second hot pressing plate 321 to be compressed. The spring buffers this reaction force, effectively preventing the first hot pressing plate 311 or the second hot pressing plate 321 from cracking due to the reaction force.

[0037] The hot pressing clamping module also includes a creasing plate 360, which has a creasing end 361 with a triangular cross-section. The creasing plate 360 ​​is positioned below the first hot pressing assembly 310 or the second hot pressing assembly 320, respectively. The creasing plate 360 ​​is positioned below the first hot pressing plate 311 or the second hot pressing plate 321, with the creasing end 361 oriented in the same direction as the hot pressing surface. The triangular shape of the creasing end 361 allows for greater pressure to be applied to the book through its pointed tip, allowing for rapid shaping of the book's spine and aesthetically pleasing appearance. It also facilitates simultaneous creasing of the book while heating, further increasing the speed of spine shaping.

[0038] A processing method of a multi-stage pressing thermoforming device, comprising:

[0039] S1. Start the feeding mechanism 10, and the book feeding module arranges and flips the books, and at the same time transfers the books to the pressing mechanism 20 and the thermoforming mechanism 30.

[0040] S2. Simultaneously start the pressing mechanism 20 and the thermoforming mechanism 30 , with the pressing mechanism 20 processing the upper end of the book, and the thermoforming mechanism 30 processing the lower end of the book, and drive the book to move to the discharge mechanism 40 .

[0041] S3. Start the discharging mechanism 40, which drives the processed books to move out of the rack so that the operator can organize the processed books.

[0042] In summary, it can be seen that the present invention has the above-mentioned excellent characteristics, which can enhance its performance unprecedented in the past and become a product with great practical value.

[0043] The above contents are only preferred embodiments of the present invention.
