Each composite module group 11 sequentially and orderly conveys multiple layers of material through the upper space, and sequentially completes gluing and composite, so that the gluing and composite process is orderly completed and is not disturbed by the replacement of the lower material.

The forming mechanism 3 processes the material corresponding to the punching mechanism 2, so as to adapt to the time difference between the punching process and the forming process.

[0043] The conveying belt 34 of the forming mechanism 3 is used for orderly conveying the material, and the input end of the conveying belt 34 is connected with the punching mechanism. The material punched at the punching mechanism is placed on the input end of the conveying belt 34 by the outfeed mechanism 24, and the material is conveyed to the material taking mechanism 35. The material taking mechanism 35 can be specifically provided as a mechanical hand, which can be provided as a clamp or a suction cup to take and place the material.

The layout table 41 is sequentially provided with a feeding station, a soaking station, a glue blowing station, a drying station and a discharging station corresponding to the conveying chain 42. The feeding station and the discharging station are used for taking and placing the material. The soaking station is provided with a soaking mechanism 44 for soaking the material with glue. The glue blowing station is provided with a glue blowing mechanism 45 for blowing the material. The drying station is provided with a drying mechanism 46 for drying the material.

[0045] As shown in Figure 9 , 10 , the feeding station corresponds to the output end of the conveying belt 34. The material is sent to the feeding station by the transfer robot. The clamp group 43 at the feeding station clamps the material. The conveying chain 42 is driven to run by a driving component such as a motor. The material reaches the soaking station. The soaking mechanism 44 at the soaking station fully soaks the material with glue. Then the material reaches the glue blowing station.

The entire conveying track is formed by the conveying chain 42 arranged in a ring shape along the layout table 41. The space occupied by the whole is optimized, facilitating arrangement and maintenance.

[0046] As an improved embodiment, the layout table 41 is provided with a ring-shaped guide rail 47 corresponding to the conveying chain 42. The clamp group 43 comprises a main frame 431 and a clamping jaw 432 arranged at the front of the main frame 431. The rear of the main frame 431 is connected to the conveying chain 42. The lower part of the main frame 431 is provided with spaced rollers 433.

[0047] As shown in Figure 9 , 10 , 11, the conveying chain 42 is arranged on the four surrounding sprockets to maintain structural stability. The clamp group 43 is slidably arranged on the ring-shaped guide rail 47. Through the connection of the conveying chain 42 and the clamp group 43, the conveying chain 42 and the clamp group 43 can maintain a good structural stability state, maintaining the stability of the structure during the whole operation and stopping.

[0049] As shown in Figure 9 , 10 , 11, through the design of the turnover plate 434, when not driven to turn outward, the clamping jaw 432 is naturally hung downward, which can make the clamped material naturally hang downward, and when running to the soaking station, the glue blowing station, the drying station and the discharging station, it can well correspond to the soaking mechanism 44, the glue blowing mechanism 45, the drying mechanism 46 and the discharging collection box below; without position adjustment of the clamping jaw 432, it can rely on the position and movable state of the soaking mechanism 44, the glue blowing mechanism 45 and the drying mechanism 46 to perform the respective processes, improve the stability of material conveying and position keeping, and reduce the adjustment steps. The push cylinder 48 only needs to be arranged at the feeding station, and does not need to be arranged at other stations, which reduces the difficulty and complexity of component arrangement and controls the component cost; the push cylinder 48 pushes the turnover plate 434, and then adjusts the clamping jaw 432 to face outward, which is convenient for corresponding to the output position of the previous process and for the transfer robot to complete the transfer of the material corresponding to the clamping jaw 432. Each group of material coating process can correspond to multiple groups of clamping jaws 432, and then complete batch material coating process, and multiple groups of clamping jaws 432 can be synchronously turned over by one push cylinder 48, which improves the efficiency of mechanism operation and material transfer and controls the component cost. As a preferred embodiment, the cylinder shaft end of the push cylinder 48 can be provided with a push roller to touch the turnover plate 434, thereby reducing the wear between components.

[0051] As shown in Figure 10As shown, the clamping jaw 432 is driven by the conveying chain 42 to the position above the soaking mechanism 44 and the glue blowing mechanism 45, and then the soaking mechanism 44 and the glue blowing mechanism 45 are lifted by the lifting mechanism 49 to adapt the height of the material on the clamping jaw 432, thereby completing the soaking and glue blowing processes; the position of the clamping jaw 432 does not need to be adjusted, thereby facilitating the simplification of the structure of the clamp group 43 and the conveying chain 42, and keeping the stable height position for operation and stopping, achieving the purpose of simplifying the equipment structure and controlling the cost. The lifting mechanism 49 is specifically provided as a cooperation structure of a lead screw 492 and a sliding block 493, the start and stop of a servo motor 491 control the rotation of the lead screw 492, and the sliding block 493 moves along the lead screw 492, thereby lifting the soaking mechanism 44 and the glue blowing mechanism 45 to the appropriate material height, such as ensuring that the material is completely soaked in the glue of the soaking mechanism 44 at the soaking mechanism 44, and ensuring that the blowing component of the glue blowing mechanism 45 blows the material directly; after completing the process, the soaking mechanism 44 and the glue blowing mechanism 45 are lowered and reset again, without affecting the continuous conveying of the clamping jaw 432 and the material.

[0052] As an improved embodiment, the soaking mechanism 44 includes a soaking box 441 and a first base 442 for mounting the soaking box 441, and the sliding block 493 is mounted on both sides of the first base 442.

[0053] As shown, Figure 10 the soaking box 441 contains glue for soaking and gluing the material; the first base 442 arranges the soaking box 441, and the sliding block 493 is mounted on both sides of the first base 442 to stably lift and adjust the height in cooperation with the lead screw 492 on both sides.

[0054] As an improved embodiment, the glue blowing mechanism 45 includes two spaced air knives 451, a collection box 452, and a second base 453 for mounting the collection box 452, and the two air knives 451 are arranged on the upper part of the collection box 452, and the sliding block 493 is mounted on both sides of the second base 453.

[0055] As shown, Figure 10 the two spaced air knives 451 are used to contain the material, and after the two air knives 451 are lifted to the material height, the strip-shaped air outlets of the two air knives 451 can blow the front and back of the material to achieve good blowing of the glue, and the collection box 452 receives the blown glue below; the second base 453 arranges the collection box 452, and the sliding block 493 is mounted on both sides of the second base 453 to stably lift and adjust the height in cooperation with the lead screw 492 on both sides.

[0056] As an improved embodiment, the drying mechanism 46 includes two spaced drying lamps 461.

[0057] AsFigure 9 , 10 As shown, the drying lamps 461 are arranged according to the height of the material suspension. The material can pass between the two drying lamps 461 that are spaced apart during the conveying process, so the drying lamps 461 themselves do not need to be adjusted in height. The two drying lamps 461 that are spaced apart can fully dry the front and back of the material, so as to achieve good shaping of the outer layer of adhesive.

[0058] As an improved specific implementation, the molding module 31 includes an upper molding die 311 and two lower molding dies 312. The upper molding die 311 is movable up and down, and the two lower molding dies 312 are movable horizontally via their respective second tracks 313. Each of the two lower molding dies 312 has two stopping positions: a molding position 32 and a loading / unloading position 33. When the lower molding die 312 is located at the molding position 32, it corresponds to the upper molding die 311 above it. The two lower molding dies 312 adjust the two positions by translating. One of the lower molding dies 312 is movable up and down. When the two lower molding dies 312 switch between the two stopping positions by translating, one of the lower molding dies 312 rises to avoid the other lower molding die 312.

[0059] like Figure 6 , 7 As shown in Figure 8, the material is conveyed to the lower forming mold 312 at the loading / unloading station 33 and then the two sets of lower forming molds 312 at the forming station 32 and the loading / unloading station 33 exchange positions. During the exchange, the liftable lower forming mold 312 rises, so that the two sets of lower forming molds 312 are misaligned and do not interfere with each other. After the exchange is completed, the lower forming mold 312 with material stays at the forming station 32. The upper forming mold 311 and the lower forming mold 312 are vertically aligned. The upper forming mold 311 is driven to descend by a lifting drive component, such as a motor, so that the upper forming mold 311 and the lower forming mold 312 close together. The upper forming mold 311 is connected to an external heating source, so as to hot press the material into the required three-dimensional shape of paper tableware. Meanwhile, the lower forming mold 312, located at the loading / unloading station 33, has its molded material picked up by the material handling mechanism 35 and transported to the adhesive coating mechanism 4. Then, the preceding material is transported to the lower forming mold 312, awaiting completion of the ongoing molding process, before the next material exchange, molding, and loading / unloading can begin. Two sets of lower forming molds 312 can store two batches of material, thus improving processing efficiency. Furthermore, the arrangement of the two sets of lower forming molds 312 exchanging positions allows loading and unloading to share a single station, optimizing material transfer and conveying, reducing the number of components, and minimizing the space occupied by the equipment.

[0060] As an improved specific embodiment, two groups of lower forming dies 312 are arranged on respective second arrangement frames 314, and two groups of second arrangement frames 314 are arranged on respective second rails 313. One of the second arrangement frames 314 is provided with a lifting cylinder 315, which drives the corresponding lower forming die 312 to lift. The two groups of lower forming dies 312 are powered to translate by a station switching motor 316. The output shaft of the station switching motor 316 is connected to a synchronous wheel 317, and a synchronous belt 318 is wound around the synchronous wheel 317. The synchronous belt 318 is connected to the two groups of second arrangement frames 314, respectively, and drives the two groups of second arrangement frames 314 to move synchronously when the synchronous belt 318 operates.

[0061] As shown in Figure 8 , the two groups of two second rails 313 are arranged at different width positions, so as not to affect the sliding of the two groups of second arrangement frames 314. The lifting cylinder 315 is arranged on the outer second arrangement frame 314, which can avoid the inner second arrangement frame 314 and the lower forming die 312 after lifting the second arrangement frame 314 and the corresponding lower forming die 312. The two groups of second arrangement frames 314 are connected to the annular upper and lower sections of the synchronous belt 318. When the synchronous belt 318 operates, the annular upper and lower sections travel in opposite directions, so as to realize the opposite direction operation of the two groups of lower forming dies 312. Thus, one station switching motor 316 can provide power to complete the two-station position conversion of the two groups of lower forming dies 312, which simplifies the component requirements and reduces the component cost.

[0062] As an improved specific embodiment, the punching mechanism 2 further comprises an inlet roller 21 and a collection roller 23. The material is sequentially conveyed through the inlet roller 21, the punching die set 22 and the collection roller 23. The punching die set 22 comprises an upper punching die 221, a lower punching die 222 and a driving mechanism 223. The material passes between the upper punching die 221 and the lower punching die 222. A plurality of punching holes 224 in the shape of paper tableware are arranged on the upper punching die 221 and the lower punching die 222. The driving mechanism 223 is arranged below the lower punching die 222 and drives the lower punching die 222 to lift, so as to punch and form the material into a plurality of paper tableware shapes when the upper punching die 221 and the lower punching die 222 are folded.

[0063] As shown in Figure 3 , 4As shown, the material output by the composite mechanism 1 is conveyed to the feeding roller 21, which is provided as two roller bodies in contact with each other. The two roller bodies clamp the material and convey the material when rotating. The material passes between the upper punching die 221 and the lower punching die 222 of the punching die set 22 and is wound onto the collection roller 23, which collects the remaining waste after punching. The feeding roller 21 and the collection roller 23 are both provided with power to actively drive the material for smooth conveying. The entire conveying process is started intermittently, so that the material is conveyed for a distance and then stopped, and then punched by the punching die set 22. According to the width of the material, the upper punching die 221 and the lower punching die 222 are provided with a proper number of punching holes 224. When the driving mechanism 223 drives the lower punching die 222 to rise, it is folded with the upper punching die 221, and the material is punched into several paper tableware shapes. Then the upper discharge mechanism 24 is lowered to take away the several paper tableware punched out.

The cross rail 242 extends across the punching die set 22 and extends to both sides. The two groups of material taking manipulators 241 correspond to one group of punching holes 224 above and below, respectively. The two groups of material taking manipulators 241 take away the material at one group of punching holes 224 and convey to the left and right sides, respectively.

[0065] As shown in Figure 3 , 4 , by arranging the two groups of punching holes 224 in front and back, the punching and forming of the two groups of materials are completed at one time. Then the two groups of material taking manipulators 241 take away the material and convey to the left and right sides along the cross rail 242, respectively.

[0066] As an improved embodiment, the material taking manipulator 241 includes a translation frame 2411, a lifting motor 2412, a lifting frame 2413, a material taking sub-module 2414, and a material taking cylinder 2415. The translation frame 2411 is horizontally slidable on the cross rail 242. The lifting frame 2413 is vertically slidable on the translation frame 2411. The lifting motor 2412 drives the lifting frame 2413 to perform lifting action. The number of the material taking sub-modules 2414 corresponds to the number of the punching holes 224. The material taking cylinder 2415 drives the material taking sub-modules 2414 to extend into the punching holes 224. The material taking sub-modules 2414 are provided as clamps or suction cups to take away the material.

[0067] As shown in Figure 3 , 4As shown, when taking materials, the translation frame 2411 moves to the upper part of the punching hole 224 along the horizontal rail 242, the lifting motor 2412 drives the lifting frame 2413 to descend, so that the material taking sub-module 2414 extends into the punching hole 224, and the material taking sub-module 2414 is provided as a clamp or a suction cup. The material is clamped or sucked by an electric or pneumatic driving mode, and then the lifting frame 2413 rises, the translation frame 2411 moves to the corresponding input end of the subsequent mechanism at the outer end along the horizontal rail 242, and then the material is output.

When the driving motors 2231 work, the driving motors 2231 drive the lower punching die 222 to ascend and descend.

[0071] As shown, Figure 5 The rotation of the driving shaft 2234 drives the crank slider mechanisms 2232 to move, so that the lower punching die 222 completes the ascending and descending action. The chain wheel and chain mechanism 2233 drives the transmission connection between the driving motors 2231 and the driving shaft 2234, so that the driving motors 2231, the driving shaft 2234, and the crank slider mechanisms 2232 can be arranged separately in the horizontal direction, which facilitates the optimization of the arrangement space of the components.
