Moreover, the specific features, structures, materials, or characteristics described may be combined in any one or more embodiments or examples in a suitable manner.

[0023] Reference Figure 1 and Figure 2 , according to the pulp molding product production line of the embodiment of the present application, comprising: Drying devices 1000, provided with at least two, for drying wet embryos to form dry embryos; The forming device 2000 is provided with at least two forming devices 2000 and the drying device 1000 correspond to each other one by one, and the corresponding forming devices 2000 and the drying device 1000 are distributed along the first direction; the forming device 2000 includes a pulp pool 210, a lower mold 220, a frame 230, a horizontal driving mechanism 240, a lifting driving mechanism 250 and an upper mold 260, the pulp pool 210 and the horizontal driving mechanism 240 are arranged on the frame 230, and the lower mold 220 is arranged on the pulp pool 2 10. The horizontal driving mechanism 240 is connected to the lifting driving mechanism 250, and the lifting driving mechanism 250 is connected to the upper mold 260. The horizontal driving mechanism 240 is used to drive the upper mold 260 to move to the top of the pulp pool 210 or into the drying device 1000. The lifting driving mechanism 250 is used to drive the upper mold 260 to rise and fall, so that the upper mold 260 cooperates with the lower mold 220 to form a wet embryo and take away the wet embryo, or the upper mold 260 places the wet embryo in the drying device 1000; A cutting device 3000, used for cutting the dry embryo to form products and waste; The transport device 4000 is located beside the drying device 1000 and the cutting device 3000 , and is used to transport the dried embryos in the drying device 1000 to the cutting device 3000 .

[0024] It can be understood that the forming device 2000 is used to form wet embryos and transfer the wet embryos to the drying device 1000. The forming device 2000 and the drying device 1000 each include at least two, and each forming device 2000 corresponds to a drying device 1000, that is, the wet embryos formed by a forming device 2000 are transferred to the corresponding drying device 1000. The corresponding forming devices 2000 and drying devices 1000 are defined as a group, and the production processes of multiple groups of forming devices 2000 and drying devices 1000 are staggered. The transport device 4000 can transfer the dry embryos in multiple drying devices 1000 to the same cutting device 3000 in turn. The cutting device 3000 can cut the dry embryos in multiple drying devices 1000 in turn to improve the utilization rate of the cutting device 3000, thereby improving the production efficiency.

[0025] For example, while the forming device 2000 of the first group is forming a wet embryo, the forming device 2000 of the second group has formed a wet embryo and transferred the wet embryo to the drying device 1000. At the same time, the drying device 1000 of the first group is drying the wet embryo, and the drying device 1000 of the second group has completed drying the wet embryo to form a dry embryo. The conveying device 4000 transfers the dry embryo in the drying device 1000 of the second group to the cutting device 3000. While the cutting device 3000 is cutting the dry embryos, the drying device 1000 of the first group completes drying the wet embryos to form dry embryos, and the transport device 4000 can transfer the dry embryos in the drying device 1000 of the first group to the cutting device 3000, while the forming device 2000 of the first group forms wet embryos and transfers the wet embryos to the drying device 1000. During this period, the drying device 1000 of the second group dries another wet embryo, and the forming device 2000 of the second group forms new wet embryos. This cycle allows the cutting device 3000 to perform cutting work uninterruptedly, thereby improving the utilization rate of the cutting device 3000.

[0026] It can also be understood that the horizontal driving mechanism 240 can drive the lifting driving mechanism 250 to move along 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. Subsequently, the lifting driving mechanism 250 drives the upper mold 260 to rise, and the upper mold 260 can absorb the wet embryo, so that the upper mold 260 rises and takes the wet embryo away from the pulp pool 210. Next, the horizontal driving mechanism 240 drives the upper mold 260 to move along 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 absorption 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 cooperate with the lower mold 220 to form the wet embryo, and can also cooperate with the horizontal drive mechanism 240 and the lifting drive mechanism 250 to transfer 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 action of the wet embryo, and improve the transfer efficiency of the wet embryo from the forming device 2000 to the drying device 1000. It should also be understood that this design can also ensure the accuracy of the placement position of the wet embryo compared to the drying device 1000, so as to improve the appearance yield of the dry embryo, avoid the placement deviation of the wet embryo relative to the drying device 1000, and the wet embryo is deformed when the upper heating mold and the lower heating mold of the drying device 1000 are hot-pressed. In addition, the forming device 2000 and the drying device 1000 correspond to each other one by one, and the forming device 2000 and the drying device 1000 are distributed along the first direction, and the horizontal drive mechanism 240 can only drive the upper mold 260 to move along the first direction.

[0027] Reference Figure 2 According to some embodiments of the present application, the drying device 1000 and the pulp pool 210 are arranged at intervals.

[0028] It is understandable that heat is generated during the drying process of the wet embryo by the drying device 1000 , 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 the wet embryo by the upper mold 260 and the lower mold 220 .

[0029] Reference Figure 1 According to some embodiments of the present application, the transport device 4000 is located on one side of the drying device 1000 in a first direction, and the cutting device 3000 is located on one side of the transport device 4000 in a second direction, and the first direction intersects with the second direction.

[0030] It can be understood that the transport 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 transport device 4000 in the second direction. Thus, the transport path of the transport device 4000 can be reduced, and the space occupied by the pulp molding product production line of the present application in the first direction can be reduced, thereby avoiding the pulp molding product production line being too long.

[0031] Specifically, the transport device 4000 is a robot, which is arranged between the two drying devices 1000. The transport 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 transport device 4000 in the second direction, which can reduce the rotation range of the robot.

[0032] Reference Figure 2 , Figure 3 , Figure 5 and Figure 6 According to some embodiments of the present application, the horizontal driving mechanism 240 includes a first mounting seat 241, a first slide rail 242, a first slide seat 243 and a horizontal driving assembly 244. The horizontal driving assembly 244 is driven and connected to the first mounting seat 241 to drive the first mounting seat 241 to move along the first direction. Two first slide rails 242 are provided. The first slide rails 242 are provided on the frame 230 and extend along the first direction. The first slide seat 243 is fixed to the first mounting seat 241, and each first slide rail 242 is slidably matched with at least one first slide seat 243. The lifting driving mechanism 250 includes 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 the second mounting seat 251 is located between the two first slide rails 242. The upper mold 260 is slidably matched with the second mounting seat 251. The lifting driving assembly 252 is driven and connected to the upper mold 260 to drive the upper mold 260 to rise and fall relative to the second mounting seat 251.

[0033] It is understood that the horizontal drive assembly 244 can drive the first mounting seat 241 to move along the first direction. When the first mounting seat 241 is driven to slide along the first direction, the first slide 243 can slide relative to the first slide rail 242, thereby improving the movement stability of the first mounting seat 241, and the second mounting seat 251 is arranged on the first mounting seat 241, and the first mounting seat 241 can drive the second mounting seat 251 to translate along the first direction. The lifting drive assembly 252 is fixed by the second mounting seat 251, and the lifting drive assembly 252 is used to drive the upper mold 260 to rise and fall. It should be understood that the second mounting seat 251 is arranged in the middle of the first mounting seat 241, and the second mounting seat 251 is located between the two first slide rails 242, so that the two first slide rails 242 are evenly stressed, which can improve the support effect of the first slide rail 242 on the first mounting seat 241 and the second mounting seat 251, and when the first mounting seat 241 drives the second mounting seat 251 to slide on the first slide rail 242, the movement stability of the first mounting seat 241 is guaranteed.

[0034] Reference Figure 2 , Figure 3 and Figure 4 According to some embodiments of the present application, the forming device 2000 further includes a protective cover 270 , and the protective cover 270 is located between the horizontal driving mechanism 240 and the pulp pool 210 .

[0035] It is understandable that the horizontal driving mechanism 240 generates debris when driving the first mounting seat 241 to move. A protective cover 270 is provided between the horizontal driving mechanism 240 and the pulp pool 210 to prevent the debris from falling into the pulp pool 210 .

[0036] Reference Figure 5 Specifically, the horizontal driving assembly 244 includes a horizontal driver 245, a first rack 246, a first transmission gear 247 and a first transmission rod 248. The first slide rail 242 and the first rack 246 are both fixed to the frame 230. The first slide rail 242 and the first rack 246 are both provided with two, and the two first racks 246 are both located between the two first slide rails 242. The first slide rail 242 and the first rack 246 are distributed along the second direction, and the second direction is perpendicular to the first direction; the horizontal driver 245 is fixedly connected to the first mounting seat 241, and the driving end of the horizontal driver 245 is connected to the first transmission rod 248. There are two first transmission gears 247, and the two first transmission gears 247 are provided on the first transmission rod 248 and are respectively engaged with one first rack 246; the protective cover 270 blocks the bottom of the first slide rail 242 and the first rack 246.

[0037] It can be understood that the horizontal driver 245 drives the first transmission rod 248 to rotate, so as to drive the first transmission gear 247 installed on the first transmission rod 248 to rotate. Since the first transmission gear 247 is meshed with the first rack 246 and the first rack 246 extends in the first direction, when the first transmission gear 247 rotates, the first transmission gear 247 rolls on the first rack 246 to drive the horizontal driver 245 to translate in the first direction through the first transmission rod 248. Since the horizontal driver 245 is fixedly connected to the first mounting seat 241, the horizontal driver 245 can drive the first mounting seat 241 to translate in the first direction. Since the first slide rail 242 also extends in the first direction and the first mounting seat 241 is fixedly connected to the first slide seat 243, when the first mounting seat 241 translates in the first direction, the first slide seat 243 slides with the first slide rail 242 to guide the movement of the first mounting seat 241. Furthermore, the two first racks 246 are located between the two first slide rails 242, so that the first mounting seat 241 is subjected to uniform force and moves stably. It can also be understood that the protective cover 270 is provided below the first slide rail 242 and the first rack 246, and the debris generated during the sliding cooperation between the first slide seat 243 and the first slide rail 242 and the debris generated during the transmission cooperation between the first rack 246 and the first transmission gear 247 will fall into the protective cover 270 to avoid falling into the pulp pool 210, thereby ensuring the cleanliness of the pulp pool 210.

[0038] Reference Figure 2 , Figure 3 , Figure 6 and Figure 7 According to some embodiments of the present application, the forming device 2000 further includes a chip box 280 , and the chip box 280 is disposed between the lifting drive mechanism 250 and the pulp pool 210 .

[0039] It is understandable that the lifting drive mechanism 250 will generate debris in the process of driving the upper mold 260 to lift and lower. A chip box 280 is set between the lifting drive mechanism 250 and the pulp pool 210, and the protective cover 270 prevents the debris from falling into the pulp pool 210.

[0040] Specifically, the chip box 280 is fixed to the upper mold 260. It is understandable that the chip box 280 is arranged on the upper mold 260, and when the lifting drive mechanism 250 drives the upper mold 260 to rise and fall, the chip box 280 can be driven to rise and fall to ensure that the chip box 280 is always located below the lifting drive mechanism 250.

[0041] Reference Figure 3 , Figure 5 , Figure 6 and Figure 7In order to further reduce the risk of debris falling into the pulp pool 210, the lifting drive assembly 252 includes a lifting drive 253 and a lifting transmission structure 254. The lifting drive 253 and the lifting transmission structure 254 are both arranged on the second mounting seat 251. The lifting transmission structure 254 is connected to the upper mold 260 for transmission. The lifting drive 253 is driven and connected to the lifting transmission structure 254 to drive the upper mold 260 to rise and fall through the lifting transmission structure 254. When the upper mold 260 moves to the top of the pulp pool 210, the projection of the lifting drive 253 and the pulp pool 210 on the horizontal plane is staggered or partially overlapped.

[0042] It is understandable that when the upper mold 260 moves to the top of the pulp pool 210, the lifting driver 253 needs to drive the upper mold 260 to move up and down through the lifting transmission structure 254, so that the upper mold 260 cooperates with the lower mold 220 to form a wet embryo and remove the wet embryo from the pulp pool 210. When the upper mold 260 moves to the top of the pulp pool 210, the projections of the lifting driver 253 and the pulp pool 210 on the horizontal plane are 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 pulp pool 210, further reducing the risk of debris falling into the pulp pool 210.

[0043] Further, refer to Figure 5 When the upper mold 260 moves to the top of the pulp pool 210, the lifting drive 253 partially overlaps with the projection of the pulp pool 210 on the horizontal plane, wherein the second mounting seat 251 is formed with a receiving groove 2511, and the overlapping part of the projection of the lifting drive 253 and the pulp pool 210 on the horizontal plane is accommodated in the receiving groove 2511.

[0044] It is understandable that when the upper mold 260 moves to the top of the pulp pool 210, the projections of the lifting driver 253 and the pulp pool 210 on the horizontal plane partially overlap, that is, partially do not overlap, which can reduce the movement stroke of the lifting driver 253 in the first direction to reduce the occupied space of the horizontal drive mechanism 240. The second mounting seat 251 is formed with a receiving groove 2511, and the overlapping part of the projection of the lifting driver 253 and the pulp pool 210 on the horizontal plane is accommodated in the receiving groove 2511, thereby, the debris formed by the non-overlapping part of the projection of the lifting driver 253 and the pulp pool 210 on the horizontal plane will fall outside the pulp pool 210, and the debris formed by the overlapping part of the projection of the lifting driver 253 and the pulp pool 210 on the horizontal plane will fall into the receiving groove 2511, thereby ensuring the cleanliness of the pulp pool 210.

[0045] Reference Figure 6 and Figure 7Regarding the specific form of the lifting transmission structure 254, the lifting transmission structure 254 includes a second slide rail 255, a second slide seat 256, a second rack 257 and a second transmission gear 258. The second slide rail 255 is fixed on the second mounting seat 251. The second rack 257 is fixed to the side of the upper mold 260 close to the second mounting seat 251. The second slide rail 255 is provided with two and both extend in the height direction. The second rack 257 is located between the two second slide rails 255. The second rack 257 and the second slide rail 255 are distributed along the second direction. The second direction is perpendicular to the first direction, the second transmission gear 258 is meshed with the second rack 257, the lifting driver 253 is fixed to the second mounting seat 251, and the driving end of the lifting driver 253 passes through the groove wall of the accommodating groove 2511 and is connected to the second transmission gear 258; each second slide rail 255 is correspondingly slidably connected with at least one second slide seat 256, and the second slide seat 256 is fixedly connected to the upper mold 260; the chip box 280 is located below the second slide rail 255 and the second rack 257, and the chip box 280 extends along the second direction.

[0046] It is understood that the driving end of the lifting driver 253 is connected to the second transmission gear 258, and the second transmission gear 258 rotates. Since the second transmission gear 258 meshes with the second rack 257 distributed in the height direction, and the second rack 257 is fixedly connected to the upper mold 260, during the rotation of the second transmission gear 258, the second transmission gear 258 rolls relative to the second rack 257 in the height direction, so that the second rack 257 and the second transmission gear 258 move relative to each other in the height direction, thereby lifting and lowering the upper mold 260 relative to the second mounting seat 251. It should be understood that since the second slide rail 255 is fixed on the second mounting seat 251, the second slide seat 256 is connected to the upper mold 260, so that when the upper mold 260 is lifted and lowered relative to the second mounting seat 251, the second slide seat 256 can slide relative to the second slide rail 255, and the sliding cooperation between the second slide rail 255 and the second slide seat 256 can guide the lifting and lowering process of the upper mold 260. It should also be understood that, since the second slide rail 255 and the second rack 257 are distributed along the second direction, the chip box 280 is extended along the second direction, and the debris generated in the process of the second slide rail 255 and the second slide seat 256 slidingly matching and the second rack 257 and the second transmission gear 258 transmitting and matching can all fall into the chip box 280. In addition, since the lifting driver 253 is partially accommodated in the receiving groove 2511, and the upper mold 260, the second slide 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 receiving groove 2511, the driving end of the lifting driver 253 is passed through the groove wall of the receiving groove 2511 to ensure that the lifting driver 253 can be connected to the second transmission gear 258.

[0047] Reference Figure 6 and Figure 8 Regarding the specific structure of the upper mold 260, the upper mold 260 includes a first connecting part 261, a second connecting part 262 and a template 263. The first connecting part 261 extends in the height direction and is connected to the driving end of the lifting drive mechanism 250. One end of the second connecting part 262 is connected to the first connecting part 261. The second connecting part 262 extends in the horizontal direction. The template 263 is arranged on the second connecting part 262. A plurality of protrusions 2631 are arranged at the lower end of the template 263.

[0048] It can be understood that the first connection part 261 is used to connect with the driving end of the lifting drive mechanism 250. Specifically, the first connection part 261 is connected with the second slide rail 255 and the second rack 257. The first connection part 261 extends in the height direction to ensure that there is a sufficient connection area between the first connection part 261 and the second slide rail 255 and the second rack 257, thereby improving the connection stability between the upper mold 260 and the lifting drive mechanism 250. The second connection part 262 extends in the horizontal direction to ensure that there is a sufficient connection area between the second connection part 262 and the template 263, thereby improving the connection stability between the second connection part 262 and the template 263. The convex part 2631 at the lower end of the template 263 can cooperate with the cavity in the lower mold 220 to form a wet embryo. Furthermore, one end of the second connection part 262 is connected to the first connection part 261, so that the first connection part 261 and the second connection part 262 are roughly L-shaped. When the horizontal driving mechanism 240 drives the upper mold 260 to enter the drying device 1000, since the second connection part 262 extends along the first direction, the second connection part 262 can make the template 263 away from the pulp pool 210, and can reduce the moving stroke of the upper mold 260 along the first direction.

[0049] Reference Figure 1 , Figure 2 and Fig.10According to some embodiments of the present application, the upper mold 260 is a male mold, and the lower mold 220 is a female mold; the pulp molding product production line also includes a feeding device 5000 and a feeding device 6000, the feeding device 5000 is arranged beside the cutting device 3000, and is used to feed the product in the die 310 of the cutting device 3000 to the feeding device 6000, and the feeding device 5000 includes a feeding mechanism 510, a translation mechanism 520, a lifting mechanism 530 and a rotating mechanism 540; the feeding mechanism 510 includes a feeding frame 511 and a plurality of feeding heads 512, and the feeding heads 512 are arranged on the feeding frame 511. On one side, the material picking head 512 is used to pick up and place products; the translation mechanism 520 drives the material picking rack 511 to drive the material picking rack 511 to move between the cutting device 3000 and the material placing device 6000; the lifting mechanism 530 drives the material picking rack 511 to drive the material picking rack 511 to rise and fall relative to the die 310 or the material placing device 6000; the rotating mechanism 540 drives the material picking rack 511 to drive the material picking rack 511 to make the side of the material picking rack 511 provided with the material picking head 512 face the die 310 or make the side of the material rack provided with the material picking head 512 face the material placing device 6000.

[0050] It is understandable that the pulp molded product produced in the present application is a bowl-shaped structure, and the size of one end of the product's bowl mouth is larger than the size of one end of the bowl bottom. When the product's bowl mouth faces upward and the bowl bottom faces downward, the product is in the forward direction, and when the product's bowl mouth faces downward and the bowl bottom faces upward, the product is in the reverse direction. Since the upper mold 260 is a convex mold and the lower mold 220 is a concave mold, after the cutting device 3000 cuts the dry embryo, the dry embryo is separated into products and waste materials. The products are carried by the punch 310, and the waste materials are left in the bottom mold 320 of the cutting device 3000. The products on the punch 310 are in the forward direction, and in order to facilitate the stacking or transmission of the products, the products need to be placed in the reverse direction on the material placement device 6000, so as to stabilize the products during the stacking process or the transmission process.

[0051] Specifically, the cutting device 3000 includes a punch die 310, a bottom die 320 and a cutting drive mechanism 330. The cutting drive mechanism 330 drives the punch die 310 and / or the bottom die 320 to move the punch die 310 and the bottom die 320 closer to or farther from each other. The punch die 310 cooperates with the bottom die 320 to cut the semi-finished product to form a product and waste. After the punch die 310 and the bottom die 320 are separated, the punch die 310 can absorb the product to leave the product in the punch die 310, and the product is in a positive direction, while the waste remains in the bottom die 320. 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 upward. The translation mechanism 520 drives the material taking mechanism 510 to translate into the cutting device 3000 and arrive between the punch die 310 and the bottom die. At this time, the material taking end of the material taking head 512 faces the punch die 310. Subsequently, the lifting mechanism 530 drives the material collecting rack 511 to rise, the material collecting rack 511 approaches the die 310, the material collecting head 512 contacts the product in the die 310, and the material collecting head 512 grabs the product in the die 310. After the material collecting head 512 grabs the product in the die 310, the lifting mechanism 530 drives the material collecting rack 511 to descend, and the material collecting head 512 takes the product away from the die 310. Next, the translation mechanism 520 drives the material collecting rack 511 to translate to the top of the material placing device 6000, and the rotating mechanism 540 drives the material collecting rack 511 to rotate so that the side of the material collecting rack 511 provided with the material collecting head 512 faces the material placing device 6000. At this time, the material collecting head 512 faces the material placing device 6000, and the material collecting head 512 drives the product to flip so that the product is in the reverse direction. Afterwards, the lifting mechanism 530 drives the material picking rack 511 to descend, so that the material picking head 512 drives the product close to the material placing device 6000, and the material picking head 512 releases the product, and the product falls on the material placing device 6000 in the opposite direction, thereby completing the unloading of the product.

[0052] Regarding the specific structure of the material placement device 6000, the material placement device 6000 includes a conveyor belt, and the material taking mechanism 510 is used to place the product on the conveyor belt, and transmit the product to the next workstation through the conveyor belt. In other embodiments, the material placement device 6000 may also include a material placement platform, and the product is stacked on the material placement platform by multiple unloading.

[0053] Reference Fig.11According to some embodiments of the present application, the translation mechanism 520 includes a translation rail 521, a translation slide 522 and a translation drive 523. The translation rails 521 are provided with two and extend in the horizontal direction. The translation slide 522 is slidably matched with the two translation rails 521. The translation drive 523 is driven and connected to the translation slide 522 to drive the translation slide 522 to translate; the lifting mechanism 530 includes a lifting actuator 531 and a lifting column 532. The lifting column 532 extends in the height direction. The lifting column 532 is located between the two translation rails 521 and is slidably matched with the middle part of the translation slide 522. The lifting actuator 531 is driven and connected to the lifting column 532 to drive the lifting column 532 to rise and fall; the rotating mechanism 540 is provided on the lifting column 532.

[0054] It can be understood that the translation drive 523 drives the translation slide 522 to move in the horizontal direction along the translation slide rail 521. Since the lifting column 532 is connected to the translation slide 522 and the rotating mechanism 540 is connected to the lifting column 532, the translation slide 522 can drive the lifting column 532 and the rotating mechanism 540 to move in the horizontal direction. In addition, the lifting actuator 531 can drive the lifting column 532 to move in the height direction relative to the translation slide 522, and the lifting column 532 can drive the rotating mechanism 540 to move in the height direction.

[0055] It can also be understood that the translation slide 522 is mounted on two translation rails 521, and the lifting column 532 is connected to the middle part of the translation slide 522 and is located between the two translation rails 521. Since the lifting column 532 has a certain length, the lifting column 532 is set between the two translation rails 521 to enable the lifting column 532 to move stably in the horizontal direction.

[0056] Specifically, the lifting column 532 passes between the two translation rails 521 along the height direction and can be lifted and lowered between the two translation rails 521 .

[0057] Specifically, the translation rail 521 extends along the distribution direction of the cutting device 3000 and the placing device 6000 .

[0058] Reference Fig.11 In order to improve the connection stability between the lifting column 532 and the translation slide 522, a through slot 5221 is formed in the middle of the translation slide 522, and the lifting column 532 passes through the through slot 5221. The lifting column 532 slides in cooperation with at least two opposite groove walls in the through slot 5221.

[0059] It is understandable that the lifting column 532 can slide relative to the groove wall of the through groove 5221, and the lifting column 532 can be lifted and lowered in the through groove 5221. Specifically, the through groove 5221 runs through the upper and lower ends of the translation slide 522, so that the lifting column 532 can pass through the through groove 5221 during the rising and falling processes, so as not to affect the normal lifting and lowering of the lifting column 532. It should be understood that by providing the through groove 5221 on the translation slide 522 and allowing the lifting column 532 to pass through the through groove 5221, the connection surface between the lifting column 532 and the translation slide 522 can be increased, so as to improve the connection stability between the lifting column 532 and the translation slide 522. In this embodiment, the opposite sides of the lifting column 532 slide with the two opposite groove walls in the through groove 5221, so as to improve the connection stability between the lifting column 532 and the translation slide 522.

[0060] Reference Figure 2 , Figure 3 and Fig. 9 According to some embodiments of the present application, the forming device 2000 further includes a spraying mechanism 290 , which is disposed on the frame 230 and is used to spray the pulp pool 210 .

[0061] It is understandable that the pulp pool 210 can be sprayed by the spraying mechanism 290 to cool down the upper mold 260, and the pulp pool 210 can be cleaned after the production is completed.

[0062] Reference Figure 4 and Fig. 9 According to some embodiments of the present application, the spray mechanism 290 includes a spray frame 291, a spray part 292, and a spray drive assembly 293. The spray part 292 is arranged on the spray frame 291, and the spray drive assembly 293 is arranged on the frame 230. The spray drive assembly 293 drives the connected spray frame 291 to drive the spray frame 291 to move along the first direction. An avoidance area 296 is formed between the spray frame 291 and the spray part 292, and the avoidance area 296 can pass through the upper mold 260.

[0063] It can be understood that the spraying part 292 is used to spray the pulp pool 210, and the spraying driving assembly 293 drives the spraying frame 291 to drive the spraying part 292 to move along the first direction to increase 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 to form an escape zone 296 between the spraying frame 291 and the spraying part 292. When the upper mold 260 and the lower mold 220 are in the mold opening state, on the projection plane perpendicular to the first direction, the projection of the upper mold 260 falls into the projection of the escape zone 296. Thus, during the process in which the horizontal driving mechanism 240 drives the upper mold 260 to transfer the dry embryo to the drying device 1000, the process in which the upper mold 260 returns to the top of the pulp pool 210, and the process in which the upper mold 260 remains stationary above the pulp pool 210, the upper mold 260 can pass through the avoidance area 296, so as not to interfere with the process in which the spray part 292 moves along the first direction, so as to improve production efficiency.

[0064] Specifically, the spray drive assembly 293 includes a spray transmission part 294 and a spray driver 295. The spray transmission part 294 is connected to the spray frame 291 by transmission. The spray driver 295 is connected to the spray transmission part 294 by driving, so as to drive the spray frame 291 to move along the first direction through the spray transmission part 294. The spray transmission part 294 is arranged at the lower end of the frame 230, the first slide rail 242 and the first rack 246 are arranged at the upper end of the frame 230, and the protective cover 270 is arranged between the spray transmission part 294 and the pulp pool 210, so that the protective cover 270 can simultaneously block the debris generated by the spray transmission part 294 to prevent the debris from falling into the pulp pool 210. The spray driver 295 is fixed to the end of the frame 230, and the projection of the spray 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 spray driver 295 will not fall into the pulp pool 210. Furthermore, the spray transmission part 294 is a belt transmission module.

[0065] The embodiments of the present application are described in detail above in conjunction with the accompanying drawings, but the present application is not limited to the above embodiments. Various changes can be made within the knowledge of ordinary technicians in the relevant technical field 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.
