[0046] Reference Figure 1 and Figure 2 A pulp molding product production line according to an embodiment of this application includes:

[0047] The drying device 1000 is provided with at least two units for drying wet embryos to form dry embryos;

[0048] At least two molding devices 2000 are provided, with each molding device 2000 corresponding to a drying device 1000, and the corresponding molding devices 2000 and drying devices 1000 are distributed along a first direction. Each molding device 2000 includes a slurry tank 210, a lower mold 220, a frame 230, a horizontal drive mechanism 240, a lifting drive mechanism 250, and an upper mold 260. The slurry tank 210 and the horizontal drive mechanism 240 are located on the frame 230, and the lower mold 220 is located on the slurry tank 210. 10. The horizontal drive mechanism 240 drives and connects to the lifting drive mechanism 250, and the lifting drive mechanism 250 drives and connects to the upper mold 260. The horizontal drive mechanism 240 is used to drive the upper mold 260 to move above the slurry tank 210 or into the drying device 1000. The lifting drive mechanism 250 drives and drives the upper mold 260 to rise and fall, so that the upper mold 260 cooperates with the lower mold 220 to form a wet blank and take away the wet blank, or so that the upper mold 260 places the wet blank into the drying device 1000.

[0049] Cutting device 3000 is used to cut dry blanks to form products and waste;

[0050] The conveying device 4000 is located beside the drying device 1000 and the cutting device 3000, and is used to convey the dry embryo in the drying device 1000 to the cutting device 3000.

[0051] It can be understood that the forming device 2000 is used to form a wet embryo and transfer the wet embryo to the drying device 1000, and the forming device 2000 and the drying device 1000 each include at least two, each forming device 2000 corresponds to a drying device 1000, that is, the wet embryo formed by one forming device 2000 is transferred to the corresponding drying device 1000. Corresponding forming device 2000 and drying device 1000 are defined as a group, and the production processes of multiple groups of forming devices 2000 and drying devices 1000 are staggered, and the conveying device 4000 can convey the dry embryo in multiple drying devices 1000 to the same cutting device 3000 in turn, and the cutting device 3000 can cut the dry embryo in multiple drying devices 1000 in turn, so as to improve the utilization rate of the cutting device 3000, thereby improving the production efficiency.

[0052] For example, when the first group of forming devices 2000 is in the process of forming a wet embryo, the second group of forming devices 2000 has formed a wet embryo and transferred the wet embryo to the drying device 1000, at the same time, the first group of drying devices 1000 is drying the wet embryo, and the second group of drying devices 1000 has completed the drying of the wet embryo to form a dry embryo, and the conveying device 4000 transfers the dry embryo in the second group of drying devices 1000 to the cutting device 3000. While the cutting device 3000 is cutting the dry embryo, the first group of drying devices 1000 completes the drying of the wet embryo to form a dry embryo, and the conveying device 4000 can convey the dry embryo in the first group of drying devices 1000 to the cutting device 3000, and the first group of forming devices 2000 forms a wet embryo and transfers the wet embryo to the drying device 1000, during which the second group of drying devices 1000 dries another wet embryo, and the second group of forming devices 2000 is in the process of forming a new wet embryo. In this way, the cutting device 3000 can continuously cut without interruption, thereby improving the utilization rate of the cutting device 3000.

[0053] It can also be understood that the horizontal driving mechanism 240 can drive the lifting driving mechanism 250 to move in the first direction to drive the upper mold 260 to move above the pulp pool 210, at this time, the lifting driving mechanism 250 drives the upper mold 260 to descend, and the upper mold 260 cooperates with the lower mold 220 to form a wet embryo, and then the lifting driving mechanism 250 drives the upper mold 260 to ascend, and the upper mold 260 can adsorb the wet embryo, so that the upper mold 260 ascends to take the wet embryo away from the pulp pool 210. Then, the horizontal driving mechanism 240 drives the upper mold 260 to move in the first direction through the lifting driving mechanism 250, and the upper mold 260 enters the drying device 1000, at this time, the lifting driving mechanism 250 drives the upper mold 260 to descend, and the upper mold 260 cancels the adsorption of the wet embryo, and the wet embryo is placed in the drying device 1000. The upper mold 260 is driven by the horizontal driving mechanism 240 and the lifting driving mechanism 250 to form and transport the next wet embryo, and at the same time, the drying device 1000 dries the wet embryo. It should be understood that the upper mold 260 can be used to form a wet embryo with the lower mold 220, and can also cooperate with the horizontal driving mechanism 240 and the lifting driving mechanism 250 to transport the wet embryo to the drying device 1000, which can reduce the use of the transfer device between the forming device 2000 and the drying device 1000, reduce the transfer operation of the wet embryo, improve the transfer efficiency of the wet embryo from the forming device 2000 to the drying device 1000, and it should also be understood that this design can also ensure the accuracy of the placement position of the wet embryo relative to the drying device 1000 to improve the appearance yield of the wet embryo, avoid the placement deviation of the wet embryo relative to the drying device 1000, and the upper heating mold and the lower heating mold of the drying device 1000 heat and press the wet embryo, and the wet embryo is deformed. Moreover, the forming device 2000 and the drying device 1000 correspond one by one, and the forming device 2000 and the drying device 1000 are distributed along the first direction, and the horizontal driving mechanism 240 can only drive the upper mold 260 to move in the first direction.

[0054] Referring to Figure 2 According to some embodiments of the present application, the drying device 1000 and the pulp pool 210 are spaced apart.

[0055] It can be understood that during the process of drying the wet embryo by the drying device 1000, heat will be generated, and the drying device 1000 and the pulp pool 210 are spaced apart to reduce the influence of the drying device 1000 on the process of forming a wet embryo by the upper mold 260 and the lower mold 220.

[0056] Referring to Figure 1 According to some embodiments of the present application, the conveying device 4000 is located on one side of the drying device 1000 in the first direction, and the cutting device 3000 is located on one side of the conveying device 4000 in the second direction, and the first direction intersects the second direction.

[0057] It can be understood that the conveying device 4000 is located on one side of the drying device 1000 in the first direction, and the cutting device 3000 is located on one side of the conveying device 4000 in the second direction, so that the conveying path of the conveying device 4000 can be reduced, and the space occupied by the pulp molded product production line in the first direction can be reduced, and the length of the pulp molded product production line can be avoided.

[0058] Specifically, the conveying device 4000 is a mechanical hand, and the mechanical hand is arranged between the two drying devices 1000. The conveying device 4000 is located on one side of the drying device 1000 in the first direction, and the cutting device 3000 is located on one side of the conveying device 4000 in the second direction, so that the rotation range of the mechanical hand can be reduced.

[0059] Referring to Figure 2 , Figure 3 , Figure 5 and Figure 6 According to some embodiments of the present application, the horizontal driving mechanism 240 comprises a first mounting seat 241, a first sliding rail 242, a first sliding seat 243, and a horizontal driving assembly 244. The horizontal driving assembly 244 is drivingly connected to the first mounting seat 241, and is used to drive the first mounting seat 241 to move in the first direction. The first sliding rail 242 is provided in two, and is arranged on the frame body 230 and extends in the first direction. The first sliding seat 243 is fixed to the first mounting seat 241, and each first sliding rail 242 is in sliding cooperation with at least one first sliding seat 243. The lifting driving mechanism 250 comprises a second mounting seat 251 and a lifting driving assembly 252. The second mounting seat 251 is fixed to the first mounting seat 241, and is located between the two first sliding rails 242. The upper die 260 is in sliding cooperation with the second mounting seat 251. The lifting driving assembly 252 is drivingly connected to the upper die 260, and is used to drive the upper die 260 to lift or lower relative to the second mounting seat 251.

[0060] It can be understood that the horizontal driving assembly 244 can drive the first mounting base 241 to move in the first direction, and when the first mounting base 241 is driven to slide in the first direction, the first sliding seat 243 can slide relative to the first sliding rail 242, thereby improving the movement stability of the first mounting base 241, and the second mounting base 251 is arranged on the first mounting base 241, and the first mounting base 241 can drive the second mounting base 251 to translate in the first direction. The lifting driving assembly 252 is fixed on the second mounting base 251, and the lifting driving assembly 252 is used to drive the upper die 260 to lift. It should be understood that the second mounting base 251 is arranged at the middle part of the first mounting base 241, and the second mounting base 251 is located between the two first sliding rails 242, so that the two first sliding rails 242 are uniformly stressed, the support effect of the first sliding rail 242 on the first mounting base 241 and the second mounting base 251 can be improved, and the movement stability of the first mounting base 241 is ensured when the first mounting base 241 drives the second mounting base 251 to slide on the first sliding rail 242.

[0061] With reference to Figure 2 , Figure 3 and Figure 4 , according to some embodiments of the present application, the forming device 2000 further comprises a protective cover 270 located between the horizontal driving mechanism 240 and the pulp pool 210.

[0062] It can be understood that the horizontal driving mechanism 240 will generate debris during the movement of the first mounting base 241, and the protective cover 270 is arranged between the horizontal driving mechanism 240 and the pulp pool 210 to block the debris from falling into the pulp pool 210.

[0063] With reference to Figure 5 , specifically, the horizontal driving assembly 244 comprises a horizontal driver 245, a first rack 246, a first transmission gear 247 and a first transmission rod 248, the first sliding rail 242 and the first rack 246 are both fixed to the frame 230, and the first sliding rail 242 and the first rack 246 are both provided with two, the two first racks 246 are located between the two first sliding rails 242, and the first sliding rail 242 and the first rack 246 are distributed along a second direction, the second direction is perpendicular to the first direction; the horizontal driver 245 is fixedly connected to the first mounting base 241, the driving end of the horizontal driver 245 is connected to the first transmission rod 248, the first transmission gear 247 is provided with two, the two first transmission gears 247 are arranged on the first transmission rod 248 and respectively engaged with a first rack 246; the protective cover 270 is shielded below the first sliding rail 242 and the first rack 246.

[0064] Understandably, the horizontal actuator 245 drives the first transmission rod 248 to rotate, thereby rotating the first transmission gear 247 mounted on the first transmission rod 248. Since the first transmission gear 247 meshes with the first rack 246, and the first rack 246 extends along the first direction, when the first transmission gear 247 rotates, it rolls on the first rack 246, thus driving the horizontal actuator 245 to translate along the first direction via the first transmission rod 248. Because the horizontal actuator 245 is fixedly connected to the first mounting base 241, it can drive the first mounting base 241 to translate along the first direction. Since the first slide rail 242 also extends along the first direction, and the first mounting base 241 is fixedly connected to the first slide block 243, when the first mounting base 241 translates along the first direction, the first slide block 243 slides against the first slide rail 242, guiding the movement of the first mounting base 241. Furthermore, the two first racks 246 are located between the two first slide rails 242, which ensures that the first mounting base 241 is subjected to uniform force and moves stably. It can also be understood that the protective cover 270 is positioned below the first slide rails 242 and the first racks 246. Debris generated during the sliding engagement of the first slide block 243 and the first slide rails 242, as well as debris generated during the transmission engagement of the first rack 246 and the first transmission gear 247, will fall into the protective cover 270, preventing it from falling into the slurry pool 210 and ensuring the cleanliness of the slurry pool 210.

[0065] Reference Figure 2 , Figure 3 , Figure 6 and Figure 7 According to some embodiments of this application, the molding apparatus 2000 further includes a chip box 280, which is disposed between the lifting drive mechanism 250 and the slurry tank 210.

[0066] It is understandable that the lifting drive mechanism 250 will generate debris during the process of driving the upper mold 260 to rise and fall. A debris box 280 is set between the lifting drive mechanism 250 and the slurry tank 210, and the protective cover 270 prevents the debris from falling into the slurry tank 210.

[0067] Specifically, the chip container 280 is fixed to the upper mold 260. It can be understood that the chip container 280 is set on the upper mold 260, and during the process of the lifting drive mechanism 250 driving the upper mold 260 to rise and fall, it can drive the chip container 280 to rise and fall, so as to ensure that the chip container 280 is always below the lifting drive mechanism 250.

[0068] Reference Figure 3 , Figure 5 , Figure 6 and Figure 7In order to further reduce the risk of debris falling into the vat 210, the lifting driving assembly 252 comprises a lifting driver 253 and a lifting transmission structure 254, both of which are arranged on the second mounting base 251. The lifting transmission structure 254 is drivingly connected to the upper die 260, and the lifting driver 253 is drivingly connected to the lifting transmission structure 254 to drive the upper die 260 to move up and down through the lifting transmission structure 254. When the upper die 260 moves above the vat 210, the lifting driver 253 is staggered or partially overlapped with the projection of the vat 210 on the horizontal plane.

[0069] It can be understood that when the upper die 260 moves above the vat 210, the lifting driver 253 needs to drive the upper die 260 to move up and down through the lifting transmission structure 254 to allow the upper die 260 to cooperate with the lower die 220 to form a wet embryo and take the wet embryo out of the vat 210. When the upper die 260 moves above the vat 210, the projection of the lifting driver 253 and the vat 210 on the horizontal plane is staggered or partially overlapped (i.e. partially staggered), so that most of the debris generated by the lifting driver 253 during operation will fall outside the vat 210, further reducing the risk of debris falling into the vat 210.

[0070] Further, referring to Figure 5 When the upper die 260 moves above the vat 210, the lifting driver 253 is partially overlapped with the projection of the vat 210 on the horizontal plane, wherein the second mounting base 251 is formed with a receiving groove 2511, and the part of the lifting driver 253 that is overlapped with the projection of the vat 210 on the horizontal plane is accommodated in the receiving groove 2511.

[0071] It can be understood that when the upper die 260 moves above the vat 210, the lifting driver 253 and the vat 210 are partially overlapped with the projection on the horizontal plane, i.e. partially not overlapped, which can reduce the moving stroke of the lifting driver 253 in the first direction, thereby reducing the occupied space of the horizontal driving mechanism 240. And the second mounting base 251 is formed with a receiving groove 2511, and the part of the lifting driver 253 that is overlapped with the projection of the vat 210 on the horizontal plane is accommodated in the receiving groove 2511, so that the part of the lifting driver 253 that is not overlapped with the projection of the vat 210 on the horizontal plane forms debris that will fall outside the vat 210, and the part of the lifting driver 253 that is overlapped with the projection of the vat 210 on the horizontal plane forms debris that will fall into the receiving groove 2511, thereby ensuring the cleanliness of the vat 210.

[0072] Referring to Figure 6 and Figure 7, the specific form of the lifting transmission structure 254, the lifting transmission structure 254 comprises a second sliding rail 255, a second sliding seat 256, a second rack 257 and a second transmission gear 258, the second sliding rail 255 is fixed on the second mounting seat 251, the second rack 257 is fixed on the upper die 260 close to one side of the second mounting seat 251, the second sliding rail 255 is provided with two and extends along the height direction, the second rack 257 is located between the two second sliding rails 255, the second rack 257 and the second sliding rail 255 are distributed along the second direction, the second direction is perpendicular to the first direction, the second transmission gear 258 is engaged with the second rack 257, the lifting driver 253 is fixed on the second mounting seat 251, and the driving end of the lifting driver 253 is connected with the second transmission gear 258 through the slot wall of the accommodating groove 2511; each second sliding rail 255 is slidably connected with at least one second sliding seat 256 corresponding to the second sliding rail 255, and the second sliding seat 256 is fixedly connected with the upper die 260; the scrap box 280 is located below the second sliding rail 255 and the second rack 257, and the scrap box 280 extends along the second direction.

[0073] It can be understood that the driving end of the lifting driver 253 is connected with the second transmission gear 258, the second transmission gear 258 rotates, and since the second transmission gear 258 is engaged with the second rack 257 distributed along the height direction, and the second rack 257 is fixedly connected with the upper die 260, in the process of rotation of the second transmission gear 258, the second transmission gear 258 rolls along the height direction relative to the second rack 257, so that the second rack 257 and the second transmission gear 258 move relative to each other in the height direction, thereby causing the upper die 260 to lift relative to the second mounting seat 251. It should be understood that since the second sliding rail 255 is fixed on the second mounting seat 251, the second sliding seat 256 is connected with the upper die 260, and thus when the upper die 260 lifts relative to the second mounting seat 251, the second sliding seat 256 can slide relative to the second sliding rail 255, and the sliding cooperation of the second sliding rail 255 and the second sliding seat 256 can guide the lifting process of the upper die 260. It should also be understood that since the second sliding rail 255 and the second rack 257 are distributed along the second direction, the scrap box 280 is extended along the second direction, and the debris generated in the process of sliding cooperation of the second sliding rail 255 and the second sliding seat 256 and the transmission cooperation of the second rack 257 and the second transmission gear 258 can all fall into the scrap box 280. Moreover, since the lifting driver 253 is partially accommodated in the accommodating groove 2511, and the upper die 260, the second sliding rail 255, the second rack 257 and the second transmission gear 258 are all located on the side of the second mounting seat 251 away from the accommodating groove 2511, by making the driving end of the lifting driver 253 pass through the slot wall of the accommodating groove 2511, it is ensured that the lifting driver 253 can be connected with the second transmission gear 258.

[0074] Referring to Figure 6 andFigure 8 With regard to the specific structure of the upper mold 260, the upper mold 260 includes a first connecting portion 261, a second connecting portion 262, and a mold plate 263. The first connecting portion 261 extends in the height direction and is connected to the driving end of the lifting driving mechanism 250. One end of the second connecting portion 262 is connected to the first connecting portion 261, and the second connecting portion 262 extends in the horizontal direction. The mold plate 263 is arranged on the second connecting portion 262, and the lower end of the mold plate 263 is provided with a plurality of protrusions 2631.

[0075] It can be understood that the first connecting portion 261 is used to be connected to the driving end of the lifting driving mechanism 250. Specifically, the first connecting portion 261 is connected to the second slide rail 255 and the second rack 257, and the first connecting portion 261 extends in the height direction to ensure that the first connecting portion 261 has sufficient connection area with the second slide rail 255 and the second rack 257, thereby improving the connection stability between the upper mold 260 and the lifting driving mechanism 250. The second connecting portion 262 extends in the horizontal direction to ensure that the second connecting portion 262 has sufficient connection area with the mold plate 263, thereby improving the connection stability between the second connecting portion 262 and the mold plate 263. The protrusions 2631 at the lower end of the mold plate 263 can cooperate with the cavities in the lower mold 220 to form a wet embryo. In addition, one end of the second connecting portion 262 is connected to the first connecting portion 261, so that the first connecting portion 261 and the second connecting portion 262 are substantially L-shaped. When the horizontal driving mechanism 240 drives the upper mold 260 to enter the drying device 1000, since the second connecting portion 262 extends in the first direction, the second connecting portion 262 can move the mold plate 263 away from the pulp pool 210, thereby reducing the moving stroke of the upper mold 260 in the first direction.

[0076] Referring to Figure 1 , Figure 2 and Figure 10According to some embodiments of the present application, the upper die 260 is a male die, and the lower die 220 is a female die; the paper pulp molded product production line further comprises a blanking device 5000 and a placing device 6000, the blanking device 5000 is arranged beside the cutting device 3000, and is used for blanking the product in the punch die 310 of the cutting device 3000 to the placing device 6000; the blanking device 5000 comprises a material taking mechanism 510, a translation mechanism 520, a lifting mechanism 530 and a rotating mechanism 540; the material taking mechanism 510 comprises a material taking frame 511 and a plurality of material taking heads 512, the material taking heads 512 are arranged on one side of the material taking frame 511, and the material taking heads 512 are used for taking and placing the product; the translation mechanism 520 is drivingly connected to the material taking frame 511, and is used for driving the material taking frame 511 to move between the cutting device 3000 and the placing device 6000; the lifting mechanism 530 is drivingly connected to the material taking frame 511, and is used for driving the material taking frame 511 to ascend and descend relative to the punch die 310 or the placing device 6000; and the rotating mechanism 540 is drivingly connected to the material taking frame 511, and is used for driving the material taking frame 511, so that the side of the material taking frame 511 provided with the material taking heads 512 faces the punch die 310 or the side of the material taking frame 511 provided with the material taking heads 512 faces the placing device 6000.

[0077] It can be understood that the paper pulp molded product produced by the present application is a bowl-shaped structure, and the size of the product bowl opening end is larger than the size of the product bowl bottom end; when the product bowl opening end faces upward and the product bowl bottom end faces downward, the product is in a normal direction, and when the product bowl opening end faces downward and the product bowl bottom end faces upward, the product is in a reverse direction. Since the upper die 260 is a male die and the lower die 220 is a female die, after the cutting device 3000 cuts the dry embryo, the dry embryo is separated into the product and the waste, the product is taken up by the punch die 310, and the waste is left on the bottom die 320 of the cutting device 3000; the product on the punch die 310 is in the normal direction, and in order to facilitate the stacking or transmission of the product, it is necessary to place the product in the reverse direction on the placing device 6000, so as to stabilize the product in the stacking process or the transmission process.

[0078] Specifically, the cutting device 3000 comprises a punch 310, a bottom die 320, and a cutting driving mechanism 330, the cutting driving mechanism 330 is connected to the punch 310 and / or the bottom die 320, and is configured to drive the punch 310 and the bottom die 320 to move towards or away from each other, the punch 310 is configured to cut the semi-finished product together with the bottom die 320 to form a product and waste, after the punch 310 and the bottom die 320 are separated, the punch 310 can adsorb the product to keep the product on the punch 310, and the product is in a forward direction, while the waste is kept on the bottom die 320. The rotating mechanism 540 is configured to drive the material taking frame 511 to rotate, so that the side of the material taking frame 511 provided with the material taking head 512 faces upwards, the translation mechanism 520 is configured to drive the material taking mechanism 510 to translate into the cutting device 3000 and to reach between the punch 310 and the bottom die 320, at this time, the material taking end of the material taking head 512 faces the punch 310. Subsequently, the lifting mechanism 530 is configured to drive the material taking frame 511 to ascend, the material taking frame 511 approaches the punch 310, the material taking head 512 contacts the product in the punch 310, and the material taking head 512 grabs the product in the punch 310. After the material taking head 512 grabs the product in the punch 310, the lifting mechanism 530 drives the material taking frame 511 to descend, and the material taking head 512 takes the product away from the punch 310. Then, the translation mechanism 520 drives the material taking frame 511 to translate above the material placing device 6000, and the rotating mechanism 540 drives the material taking frame 511 to rotate, so that the side of the material taking frame 511 provided with the material taking head 512 faces the material placing device 6000, at this time, the material taking head 512 faces the material placing device 6000, and the material taking head 512 turns over the product to make the product in a reverse direction. Subsequently, the lifting mechanism 530 drives the material taking frame 511 to descend, so that the material taking head 512 takes the product close to the material placing device 6000, the material taking head 512 releases the product, and the product in the reverse direction falls on the material placing device 6000, thereby completing the product unloading.

[0079] As to the specific structure of the material placing device 6000, the material placing device 6000 comprises a conveying belt, and the material taking mechanism 510 is configured to place the product on the conveying belt, and the product is transmitted to the next station through the conveying belt. In other embodiments, the material placing device 6000 can also comprise a material placing platform, and the product is stacked on the material placing platform through multiple times of unloading.

[0080] Referring to Figure 11According to some embodiments of the present application, the translation mechanism 520 comprises two translation sliding rails 521 extending horizontally, a translation sliding base 522 slidingly fitted with the two translation sliding rails 521, and a translation driving member 523 drivingly connected with the translation sliding base 522 for driving the translation sliding base 522 to translate; the lifting mechanism 530 comprises a lifting actuator 531 and a lifting column 532 extending along a height direction, the lifting column 532 being located between the two translation sliding rails 521 and slidingly fitted with a middle portion of the translation sliding base 522, and the lifting actuator 531 drivingly connected with the lifting column 532 for driving the lifting column 532 to lift; and the rotating mechanism 540 is arranged on the lifting column 532.

[0081] It can be understood that the translation driving member 523 drives the translation sliding base 522 to move along the horizontal direction of the translation sliding rails 521, and since the lifting column 532 is connected with the translation sliding base 522 and the rotating mechanism 540 is connected with the lifting column 532, the translation sliding base 522 can drive the lifting column 532 and the rotating mechanism 540 to move along the horizontal direction. In addition, the lifting actuator 531 can drive the lifting column 532 to move along the height direction relative to the translation sliding base 522, and the lifting column 532 can drive the rotating mechanism 540 to move along the height direction.

[0082] It can also be understood that the translation sliding base 522 is arranged on the two translation sliding rails 521, and the lifting column 532 is connected with the middle portion of the translation sliding base 522 and located between the two translation sliding rails 521. Since the lifting column 532 has a certain length, the lifting column 532 is arranged between the two translation sliding rails 521 so as to stabilize the movement of the lifting column 532 along the horizontal direction.

[0083] Specifically, the lifting column 532 extends along the height direction through the space between the two translation sliding rails 521, and can lift between the two translation sliding rails 521.

[0084] Specifically, the translation sliding rails 521 extend along the distribution direction of the cutting device 3000 and the material placing device 6000.

[0085] Referring to Figure 11 In order to improve the connection stability of the lifting column 532 and the translation sliding base 522, a through slot 5221 is formed in the middle portion of the translation sliding base 522, the lifting column 532 is arranged through the through slot 5221, and the lifting column 532 is slidingly fitted with at least two opposite slot walls in the through slot 5221.

[0086] It can be understood that the lifting column 532 can slide relative to the slot wall of the through slot 5221, and the lifting column 532 can be lifted in the through slot 5221. Specifically, the through slot 5221 penetrates the upper and lower ends of the translation sliding seat 522, so that the lifting column 532 can pass out of the through slot 5221 during the lifting process and the lowering process, so as to not affect the normal lifting of the lifting column 532. It should be understood that by providing the through slot 5221 on the translation sliding seat 522 and making the lifting column 532 pass through the through slot 5221, the connection surface of the lifting column 532 and the translation sliding seat 522 can be increased, so as to improve the connection stability of the lifting column 532 and the translation sliding seat 522. In the embodiment, the opposite sides of the lifting column 532 are in sliding fit with two opposite slot walls in the through slot 5221, so as to improve the connection stability of the lifting column 532 and the translation sliding seat 522.

[0087] With reference to Figure 2 , Figure 3 and Figure 9 , according to some embodiments of the present application, the forming device 2000 further comprises a spraying mechanism 290, which is arranged on the frame 230 and is used for spraying the slurry pool 210.

[0088] It can be understood that the slurry pool 210 can be sprayed by the spraying mechanism 290, so as to cool the upper die 260 and clean the slurry pool 210 after production is completed.

[0089] With reference to Figure 4 and Figure 9 , according to some embodiments of the present application, the spraying mechanism 290 comprises a spraying frame 291, a spraying part 292 and a spraying driving assembly 293. The spraying part 292 is arranged on the spraying frame 291, and the spraying driving assembly 293 is arranged on the frame 230 and is drivingly connected to the spraying frame 291, so as to drive the spraying frame 291 to move in the first direction. An avoiding area 296 is formed between the spraying frame 291 and the spraying part 292, and the avoiding area 296 can pass through the upper die 260.

[0090] It can be understood that the spraying part 292 is used for spraying the pulp pool 210, the spraying driving assembly 293 drives the spraying frame 291 to drive the spraying part 292 to move in the first direction, so as to improve the spraying range of the spraying part 292. The spraying frame 291 extends in the height direction, and the spraying part 292 extends in the horizontal direction, so as to form an avoidance area 296 between the spraying frame 291 and the spraying part 292. When the upper mold 260 and the lower mold 220 are in the open mold state, the projection of the upper mold 260 falls into the projection of the avoidance area 296 on the projection plane perpendicular to the first direction. Therefore, in the process that the horizontal driving mechanism 240 drives the upper mold 260 to transmit the dry embryo to the drying device 1000, the process that the upper mold 260 returns to above the pulp pool 210, the process that the upper mold 260 is stationary above the pulp pool 210, the upper mold 260 can pass through the avoidance area 296, so as to not interfere with the process that the spraying part 292 moves in the first direction, so as to improve the production efficiency.

[0091] Specifically, the spraying driving assembly 293 includes a spraying transmission part 294 and a spraying driver 295. The spraying transmission part 294 is in transmission connection with the spraying frame 291, and the spraying driver 295 is in driving connection with the spraying transmission part 294, so as to drive the spraying frame 291 to move in the first direction through the spraying transmission part 294. The spraying transmission part 294 is arranged at the lower end of the frame body 230, the first sliding rail 242 and the first rack 246 are arranged at the upper end of the frame body 230, and the protective cover 270 is arranged between the spraying transmission part 294 and the pulp pool 210, so that the protective cover 270 can shield the debris generated by the spraying transmission part 294 at the same time, so as to avoid the debris from falling into the pulp pool 210. The spraying driver 295 is fixed to the end of the frame body 230, and the projection of the spraying driver 295 on the horizontal plane is staggered with the projection of the pulp pool 210 on the horizontal plane, so that the debris generated by the spraying driver 295 will not fall into the pulp pool 210. Further, the spraying transmission part 294 is a belt transmission module.

[0092] The above describes the embodiments of the present application in detail in combination with the drawings, but the present application is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the purpose of the present application. In addition, the embodiments of the present application and the features in the embodiments can be combined with each other without conflict.
