Description

Technical Field

[0001] This invention relates to the field of compression forming, specifically to a fast and precise compression forming system and process. Background Technology

[0002] An automated production line is a form of production organization where the product manufacturing process is realized by an automated machine system. It is a further development of the continuous production line. The workpiece is automatically transferred from one machine tool to another, where it is automatically processed, loaded, unloaded, and inspected. Workers' tasks are limited to adjusting, supervising, and managing the automated line; they do not participate in direct operation. All machinery operates at a uniform pace, and the production process is highly continuous.

[0003] However, there is currently a lack of fully automated production lines for the forming of granular products on the market. Existing forming processes for granular seed products mainly involve placing the seed material in a forming device and pressing it from both top and bottom using a flat forming surface. This results in an aesthetically pleasing seed shape that meets market preferences and company product requirements. Current forming technologies typically use hydraulic balers or cylindrical pressing machines. This involves feeding a fixed quantity of round seed pellets into a fixed space, then using hydraulic equipment to compress the space, causing the pellets to deform from an oval shape to a flat shape. The flat surface is then cut in half to obtain two finished seed pellet sheets. These sheets have flat openings and a textured edge resembling a lotus leaf, resulting in an attractive appearance that meets current market aesthetic requirements for finished seed pellet products. However, traditional seed pressing uses a large-scale centralized mixing and pressing method, with each pressing cavity containing 80-500 kg of product seed material. The baling seed pressing machine presses about 500 kg of seeds at a time, and the pressing time is 1-12 hours. The cylindrical seed pressing machine presses 80-100 kg of seeds at a time, and the pressing time is 24-72 hours. The quality of the pressed seeds cannot be guaranteed, and the amount of seeds wasted is large. The product seed material is heated to 45-65℃ by microwave heating or steam heating alone, which is slow and easy to overheat and damage the quality of the product seed material.

[0004] A search revealed that patent number "CN218605016U" discloses a rapid forming machine. A conveyor belt is installed between opposing presses, and a forming mold is fitted onto each press. The forming mold contains heating and cooling components. An X-axis moving module is located outside the forming mold, equipped with a feeding device and a fixed feeding frame. A suction cup assembly is located within the feeding frame, and a solenoid valve group and a vacuum storage tank are fitted onto the suction cup assembly. A servo motor is connected to a Y-axis moving module, one end of which is fixedly connected to the suction cup assembly. However, this solution is structurally complex and still requires manual intervention for tasks such as feeding and cleaning the mold, impacting production efficiency. Summary of the Invention

The multiple adsorption ports correspond one-to-one with the multiple material handling troughs 141. The exhaust port is connected to the fan 117 via an exhaust pipe. The transfer cylinder 114 can be activated to lower the adsorption plate 116 to be close to the product material. After the fan 117 is activated, the adsorption plate 116 can adsorb all the product material that has fallen into the material feeding trough 141 at once, and then transport the product material to the forming groove 101 of the lower mold 10 on the material preparation component through the electronic slide rail 118, which greatly improves the efficiency of material preparation.

[0088] Specifically, the adsorption plate 116 has an adsorption nozzle at its adsorption port, and the adsorption nozzle has a through hole. The tail end of the adsorption nozzle is shaped like an inverted bowl and is made of elastic material. The adsorption nozzle can enhance the sealing between the adsorption plate 116 and the product seed material, forming a better vacuum environment, which greatly enhances the adsorption capacity of the adsorption plate 116 for the product seed material and reduces the probability of the product seed material falling off the adsorption plate 116.

[0089] Please see Figures 6-8 Specifically, the lifting material preparation platform 119 is provided with lifting screws 120 and lifting motors 121 on both sides. The lifting screws 120 are connected to the output shaft of the lifting motors 121, and lifting screw nuts 122 are sleeved on the lifting screws 120. The lifting material preparation platform 119 is fixedly connected to the lifting screw nuts 122. The lifting material preparation platform 119 is provided with first guide wheel sets on both sides for docking and conveying the lower molds 10 on the lifting material preparation platform 119. Through the lifting motors 121 and lifting screws 120, the lifting material preparation platform 119 can move back and forth between the upper conveying device 6 and the lower conveying device 7, so that a single lifting material preparation platform 119 can both send out the lower molds 10 that have completed material preparation and receive the returned empty lower molds 10 and participate in its material preparation and sending process.

[0090] Specifically, the first guide wheel assembly includes a first guide motor 123, at least one first drive sprocket 124, multiple first driven sprockets 125, and multiple first guide wheels 126. The first drive sprocket 124 and the first driven sprockets 125 are interconnected by a chain. The first guide wheel 126 is coaxially connected to the first drive sprocket 124 and the first driven sprockets 125, and the first guide wheel 126 contacts the lower surface of the lower mold 10. The first guide wheel assembly serves to drive and connect the lower mold 10 as it is conveyed from the lower conveyor 7 to the lifting material preparation platform 119, or from the lifting material preparation platform 119 to the upper conveyor 6, making the transfer process smoother.

[0091] Specifically, the front end of the lifting material preparation platform 119 is provided with a front limiting block 127. The front limiting block 127 is arranged vertically, one end of the front limiting block 127 is fixedly connected to the lifting material preparation platform 119, and the other end of the front limiting block 127 is used to abut against the lower mold 10. When the lifting material preparation platform 119 receives the returned lower mold 10, the front limiting block 127 can block the direction of the mold's forward movement, preventing the lower mold 10 from falling off the lifting material preparation platform 119.

[0092] Specifically, a rotary clamping cylinder 128 is provided at the rear end of the lifting material preparation platform 119. The cylinder body of the rotary clamping cylinder 128 is fixedly connected to the lower surface of the lifting material preparation platform 119. The actuating end of the rotary clamping cylinder 128 is a rear limiting block 129, which is used to abut against the lower mold 10. By activating the rotary clamping cylinder 128, the rear limiting block 129 is rotated to a vertically upward position, thereby locking the front and rear ends of the lower mold 10 by the clamping of the front limiting block 127 and the rear limiting block 129. This prevents the lower mold 10 from shifting its position during the movement of the lifting material preparation platform 119, which would affect the correspondence between the product seed material on the adsorption plate 116 and the forming groove 101 on the lower mold 10.

[0093] Specifically, the front limiting block 127 and the rear limiting block 129 are used to abut one end of the lower mold 10, and an adjustment hole 130 is provided in the horizontal direction. An adjustment screw 131 is provided in the adjustment hole 130; so that the operator can adjust the error caused by wear of the feeding device 1 during long-term operation by adjusting the adjustment screw 131.

[0094] Please see Figure 9 Heating device 2: The heating device 2 is equipped with a heating chamber 21, which is located above the upper conveying device 6. The heating chamber 21 has channels at both ends for the upper conveying device 6 to pass through. High-temperature steam can be introduced into the heating chamber 21. A microwave heater or an infrared heater can also be installed inside the heating chamber 21. The heating method for the product seed material can be a combination of microwave heating and steam heating, or a combination of infrared heating and steam heating. This allows for rapid heating of the product seed material, improving efficiency, and also allows for control of the moisture content of the product seed material by adjusting the power of the two heating methods. When the product seed material is relatively dry, the steam flow can be increased and the microwave or infrared power reduced. If the product seed material is relatively wet, the steam flow can be reduced and the microwave or infrared power increased. Typically, the product seed material on the lower mold 10 is heated to 85-160℃, while controlling the moisture content variation of the product seed material to not exceed ±1%.

[0095] The heating device 2 is also provided with a preheating chamber 22, which is located on the lower conveying device 7. The preheating chamber 22 has channels at both ends for the lower conveying device 7 to pass through. The unloaded mold can also be preheated in the preheating chamber 22 by high-temperature steam and / or infrared heater.

[0096] Please see Figures 10-14The hot pressing device 3 includes a hot press frame 31, a first support plate 311, an upper hot press plate 33, a lower hot press plate 34, and a first press 32. The lower hot press plate 34 is placed flat on the hot press frame 31. The first support plate 311 is fixedly connected to the top of the hot press frame 31 by four support columns, and the first support plate 311 is located directly above the lower hot press plate 34. The first press 32 is fixedly connected to the first support plate 311. The first press 32 is arranged vertically, and the actuator of the first press 32 faces the lower hot press plate 34. The lower hot press plate 34 is used to support the lower mold 10. The actuator of the first press 32 is fixedly connected to the upper mold 9. A first mounting plate 35 and a hot press top are also provided between the first press 32 and the upper mold 9. The first mounting plate 35 is fixedly connected to the actuator rod of the first press 32. The lower surface of the first mounting plate 35 is provided with a hot-pressing ejector cylinder 37. The lower surface of the first mounting plate 35 is provided with multiple first sliding rods 38 vertically. The end of the first sliding rod 38 away from the first mounting plate 35 is connected to the upper hot-pressing plate 33. The hot-pressing ejector plate 36 is sleeved on the first sliding rod 38. The hot-pressing ejector plate 36 is fixedly connected to the actuator rod of the hot-pressing ejector cylinder 37. The upper hot-pressing plate 33 is connected to the end of the first sliding rod 38 away from the first mounting plate 35. The upper mold 9 is connected to the lower surface of the upper hot-pressing plate 33. The lower surface of the hot-pressing ejector plate 36 is provided with multiple ejector pins vertically. The upper hot-pressing plate 33 and the upper mold 9 are provided with through holes corresponding to the ejector pins. By transporting the lower mold 10, which contains the product seed material to be formed, to the lower hot press plate 34, the first press 32 is started to apply pressure to the product seed material through the forming protrusions 91 of the upper mold 9 to achieve the effect of shaping the product seed material. At the same time, in order to prevent the product seed material from sticking to the upper mold 9 during the pressing process of the lower mold 10 and the upper mold 9, a hot press ejector plate 36 is set up. When the forming is completed and the upper mold 9 and the lower mold 10 are separated, the hot press ejector cylinder 37 is started simultaneously. The hot press ejector cylinder 37 pushes the hot press ejector plate 36 downward, so that the ejector pins below the hot press ejector plate 36 can push the product seed material stuck to the upper mold 9 off. The position of the ejector pins corresponds exactly to the center of each forming protrusion 91 on the upper mold 9. Compared with the existing method of manually manipulating the product seed material, the present invention can better maintain the integrity of the product seed material and reduce the waste rate.

[0097] Specifically, the upper hot press plate 33 and the lower hot press plate 34 are provided with a first temperature control channel 39 along the horizontal direction. High-temperature steam or hot water can be introduced into the first temperature control channel 39 to heat the upper mold 9 and the lower mold 10, ensuring that the surface temperature of the upper hot press plate 33 and the lower hot press plate 34 is 85-160℃, and finally realizing the hot pressing process. Hot pressing helps to better shape the product material and improve the shaping quality of the product material. When the upper mold 9 and the lower mold 10 are closed, the minimum limit distance between the upper and lower molds 10 can be adjusted by the limiting block. If the overall diameter of the pressed product material is large, the limit distance can be increased, and if the diameter of the product material is small, the limit distance can be decreased. The purpose is to achieve a very good flattening and shaping effect in a short time, minimize the rebound of the product material after pressing, and ensure that the product material is not cracked or damaged.

[0098] The pressure on the first press 32 is adjustable. Its maximum design pressure can be calculated based on the number of forming grooves 101 on the lower mold 10, and can be designed with an average pressure of 80-200 kg per product seed. To reduce the probability of cracking the seed, the first press 32 can be pressed down in two stages. First, the first press 32 pushes the upper mold 9 directly down to the first position, which is 0.5-2 mm larger than the minimum limit position between the upper mold 9 and the lower mold 10. It stays at the first position for 1-10 seconds. Then, the first press 32 continues to push the upper mold 9 down to the minimum limit position between the upper mold 9 and the lower mold 10, and then maintains the pressure to maintain this forming distance. At the same time, the upper hot platen and the lower hot platen 34 continue to maintain heating. After heating and holding the pressure for 30-150 seconds, the mold is opened, and the upper mold 9 rises back to the initial position.

[0099] Specifically, the first mounting plate 35 is vertically provided with multiple second slide rods 312, the end of each second slide rod 312 away from the mounting plate passing through the first support plate 311. Specifically, the length of the second slide rod 312 is greater than the maximum stroke of the actuator rod of the first press 32. During the pressing process, the second slide rods 312 help stabilize the posture of the first mounting plate 35, improving stability during the pressing process.

[0100] Please see Figure 15 and Figure 16Specifically, the cold pressing device 4 includes a cold pressing frame 41, a second support plate 411, an upper cold pressing plate 43, a lower cold pressing plate 44, and a second press 42. The lower cold pressing plate 44 is placed flat on the cold pressing frame 41. The second support plate 411 is fixedly connected to the upper part of the cold pressing frame 41 by four support rods, and the second support plate 411 is located directly above the lower cold pressing plate 44. The second press 42 is fixedly connected to the second support plate 411. The second press 42 is arranged vertically, and the actuator of the second press 42 faces the lower cold pressing plate 44. The lower cold pressing plate 44 is used to support the lower mold 10. The actuator of the second press 42 is fixedly connected to the upper mold 9. A second mounting plate 45 is also provided between the second press 42 and the upper mold 9. The ejector plate 46 is fixedly connected to the actuator rod of the second mounting plate 45 and the second press 42. The lower surface of the second mounting plate 45 is provided with a cold-pressing ejector cylinder 47. The lower surface of the second mounting plate 45 is provided with multiple third slide rods 48 vertically. The two ends of the third slide rods 48 away from the second mounting plate 45 are connected to the upper cold-pressing plate 43. The cold-pressing ejector plate 46 is sleeved on the third slide rods 48. The cold-pressing ejector plate 46 is fixedly connected to the actuator rod of the cold-pressing ejector cylinder 47. The upper cold-pressing plate 43 is connected to the two ends of the third slide rods 48 away from the second mounting plate 45. The upper mold 9 is connected to the lower surface of the upper cold-pressing plate 43. The lower surface of the cold-pressing ejector plate 46 is provided with multiple ejector pins vertically. The upper cold-pressing plate 43 and the upper mold 9 are provided with through holes corresponding to the ejector pins. By transporting the lower mold 10, which contains the product seed material to be formed, to the lower cold press plate 44, the second press 42 is activated to apply pressure to the product seed material through the forming protrusions 91 of the upper mold 9, thereby achieving the effect of shaping the product seed material. At the same time, in order to prevent the product seed material from sticking to the upper mold 9 during the pressing process of the lower mold 10 and the upper mold 9, a cold press ejector plate 46 is set up. When the forming is completed and the upper mold 9 and the lower mold 10 are separated, the cold press ejector cylinder 47 is activated simultaneously. The cold press ejector cylinder 47 pushes the cold press ejector plate 46 downward, so that the ejector pins below the cold press ejector plate 46 can push the product seed material stuck to the upper mold 9 off. The position of the ejector pins corresponds exactly to the center of each forming protrusion 91 on the upper mold 9. Compared with the existing method of manually manipulating the product seed material, the present invention can better maintain the integrity of the product seed material and reduce the waste rate.

[0101] Specifically, the upper cold pressing plate 43 and the lower cold pressing plate 44 are provided with a second temperature control channel 49 along the horizontal direction. The second temperature control channel 49 continuously circulates either cold water or ethylene glycol. The second press 42 controls the upper mold 9 to press down and close the mold. The first press reaches the minimum limit position of the upper mold 9 and the lower mold 10, and this pressure is maintained while the upper and lower cold pressing plates 44 continue to maintain cooling until the surface temperature of the lower mold 10 drops to a set temperature, generally 5-20℃, preferably 5℃. Simultaneously, the pressure holding and cooling time exceeds the designed value, generally 30-240 seconds, at which point the mold can be opened, allowing the upper cold pressing plate 43 and the upper mold 9 to rise. This ultimately achieves the cold pressing process. Cold pressing is generally placed after hot pressing and is used to rapidly cool and solidify the hot-pressed product material to prevent springback.

[0102] Specifically, the second mounting plate 45 is vertically provided with multiple fourth slide rods 412, the end of each fourth slide rod 412 away from the second mounting plate 45 passing through the second support plate 411. Specifically, the length of each fourth slide rod 412 is greater than the maximum stroke of the actuator rod of the second press 42. During the pressing process, the fourth slide rods 412 help stabilize the posture of the second mounting plate 45, improving stability during the cold pressing process.

[0103] Please see Figure 12 and 13Specifically, the upper conveying device 6 on the hot pressing device 3 and the cold pressing device 4 is located on both sides of the lower hot pressing plate 34 and the lower cold pressing plate 44. Multiple fifth sliding rods 68 and supporting cylinders 67 are vertically arranged on both the hot pressing frame 31 and the cold pressing frame 41. These are respectively the first supporting cylinder on the hot pressing frame 31 and the second supporting cylinder on the cold pressing frame 41. The upper conveying device 6 is slidably connected to the fifth sliding rods 68. The cylinder body of the supporting cylinder 67 is fixedly connected to the hot pressing frame 31 and the cold pressing frame 41. The actuator of the supporting cylinder 67 abuts against the lower surface of the upper conveying device 6, allowing the hot pressing device 3 and the cold pressing device 4 to connect to other process equipment on the forming production line, such as the heating device 2 and the feeding device 5, through the upper conveying device 6. When the lower mold 10 loaded with product seed material is transferred from the heating device 2 to the hot pressing device 44... When transferring from the hot pressing device 3 to the cold pressing device 4, the supporting cylinder 67 supports the upper conveying device 6 to a position higher than the lower hot pressing plate 34 or the lower cold pressing plate 44. After the upper conveying device 6 has completely transported the lower mold 10 above the lower hot pressing plate 34 or the lower cold pressing plate 44, the supporting cylinder 67 drives the upper conveying device 6 to descend, so that the lower mold 10 falls onto the lower hot pressing plate 34 or the lower cold pressing plate 44 for pressing. After pressing is completed, the supporting cylinder 67 drives the upper conveying device 6 to rise again to support the lower mold 10 and transport the lower mold 10 to the next process. This realizes the automatic cycle of small and medium batch pressing, which not only improves the automation level of the pressing process and reduces labor intensity, but also maintains the production efficiency of the traditional large-batch pressing production line for cylindrical tubes, and also improves the quality of pressing and shaping and reduces the waste rate, achieving three benefits in one go.

[0104] Specifically, the upper conveying device 6 includes a mounting component 61, at least one conveying motor 62, a drive shaft 63, a first bevel gear 64, a second bevel gear 65, and multiple conveying wheels 66. The conveying motor 62 is fixedly connected to the mounting component 61. The drive shaft 63 is rotatably connected to the mounting component 61. Multiple first bevel gears 64 are sleeved on the drive shaft 63. The conveying wheels 66 are rotatably connected to the side of the mounting component 61 away from the drive shaft 63. A second bevel gear 65 is mounted on the side of the mounting component 61 close to the drive shaft 63. The second bevel gear 65 and the conveying wheels 66 are coaxially connected. The first bevel gear 64 and the second bevel gear 65 mesh. The output shaft of the conveying motor 62 is connected to the conveying wheels 66. The transmission motor 62 drives one of the transmission wheels 66 to rotate, which in turn drives the second bevel gear 65 and the transmission shaft 63 to rotate. Then, the multiple first bevel gears 64 on the transmission shaft 63 drive the multiple second bevel gears 65 and the multiple transmission wheels 66 to rotate synchronously, ultimately realizing the movement of the lower mold 10 driven by the multiple transmission wheels 66. It is worth noting that the above structure is the preferred structure provided in this embodiment, but the present invention is not limited to the above structure. Any existing transmission mechanism that can achieve the same effect can also be used and is within the protection scope of the present invention.

[0105] Please see Figures 17-19 The feeding device 5 includes a feeding frame 51, a fixed frame 52, and a lifting and tilting feeding platform 53. The fixed frame 52 is connected to the feeding frame 51. The lifting and tilting feeding platform 53 is placed horizontally above the fixed frame 52, and one end of the lifting and tilting feeding platform 53 is rotatably connected to the fixed frame 52. A tilting assembly is provided between the fixed frame 52 and the lifting and tilting feeding platform 53. A feeding ejector plate 54 and a feeding ejector cylinder 55 are provided below the lifting and tilting feeding platform 53. The cylinder body of the feeding ejector cylinder 55 is fixedly connected to the feeding ejector plate 54. The actuator of the feeding ejector cylinder 55 passes through the feeding ejector plate 54 and is fixedly connected to the lifting and tilting feeding platform 53. Multiple ejector pins are vertically arranged on the upper surface of the feeding ejector plate 54. The lifting and tilting feeding platform 53 is provided with through holes corresponding to the ejector pins. The flipping assembly provides power to the lifting and flipping unloading platform 53. While the lifting and flipping unloading platform 53 is flipping, the unloading ejector cylinder 55 is activated to push the product seed material stuck in the lower mold 10 out through the ejector pin. The lower mold 10 also has a through hole for the ejector pin to pass through, which greatly improves the efficiency of processing and production, and at the same time prevents damage to the product seed material when it is manually handled.

[0106] Please see Figure 20 Specifically, the tilting assembly includes a tilting cylinder 56, a connecting rod 57, a first connecting rod 58, and a second connecting rod 59. The cylinder body of the tilting cylinder 56 is rotatably connected to the fixed frame 52. The connecting rod 57 is fixedly connected to the actuating rod of the tilting cylinder 56, and the actuating rod is perpendicular to the connecting rod 57. The first connecting rod 58 and the second connecting rod 59 are hinged to both ends of the connecting rod 57. The end of the first connecting rod 58 away from the connecting rod 57 is rotatably connected to the lifting and tilting unloading platform 53. The end of the second connecting rod 59 away from the connecting rod 57 is rotatably connected to the lifting and tilting unloading platform 53. One end of the connecting rod 57 is rotatably connected to the fixed frame 52, and the first connecting rod 58 and the second connecting rod 59 are both perpendicular to the connecting rod 57. When the tilting cylinder 56 is in the retracted state, the first connecting rod 58 and the second connecting rod 59 form an acute angle. At this time, the lifting tilting unloading platform 53 is in a horizontal position. When the tilting cylinder 56 is in the extended state, the first connecting rod 58 and the second connecting rod 59 form an obtuse angle. At this time, the lifting tilting unloading platform 53 is tilted 60°, which facilitates the product seed material placed in the lower mold 10 on the lifting tilting unloading platform 53 to roll down and complete the unloading.

[0107] Please see Figure 21The present invention also provides an alternative flipping assembly, which includes a flipping motor 510, a flipping lead screw 511, a flipping lead screw nut 512, and a flipping connecting rod 513. Both the flipping motor 510 and the flipping lead screw 511 are connected to a fixed frame 52. The output shaft of the flipping motor 510 is connected to the flipping lead screw 511. The flipping lead screw nut 512 is sleeved on the flipping lead screw 511. One end of the flipping connecting rod 513 is rotatably connected to the flipping lead screw nut 512, and the other end of the flipping connecting rod 513 is rotatably connected to the lifting and flipping unloading platform 53. The flipping motor 510 drives the flipping lead screw 511 to rotate, and the flipping lead screw nut 512 slides back and forth along the flipping lead screw 511, causing the angles between the flipping connecting rod 513 and the lifting and flipping unloading platform 53, and between the flipping connecting rod 513 and the flipping lead screw 511, to gradually increase. Ultimately, the lifting and flipping unloading platform 53 is supported on one side by the flipping connecting rod 513, forming a flipping effect.

[0108] Specifically, please refer to Figure 22 The fixed frame 52 has vertically arranged lifting screws 514 and lifting motors 515 on both sides. The lifting screws 514 are connected to the output shaft of the lifting motors 515, and lifting screw nuts 516 are fitted on the lifting screws 514. The fixed frame 52 is fixedly connected to the lifting screw nuts 516. The lifting and tilting unloading platform 53 also has second guide wheel sets on both sides for docking and conveying the lower mold 10 on the lifting and tilting unloading platform 53. The lifting screws 514 and lifting screw nuts 516 can automatically transfer the unloaded lower mold 10 from the upper conveying device 6 to the lower conveying device 7, improving the efficiency of the transfer of the lower mold 10 and thus improving the working efficiency of the entire processing production line.

[0109] Please see Figure 23Specifically, the second guide wheel assembly includes a second guide motor 517, at least one second drive sprocket 518, multiple second driven sprockets 519, and multiple second guide wheels 520. The second drive sprocket 518 and the second driven sprockets 519 are interconnected by a chain. The second guide wheel 520 is coaxially connected to the second drive sprocket 518 and the second driven sprocket 519, and the second guide wheel 520 contacts the lower surface of the lower mold 10. The second guide wheel assembly serves to drive and connect the lower mold 10 as it is conveyed from the upper conveying device 6 to the lifting and tilting unloading platform 53, or from the lifting and tilting unloading platform 53 to the lower conveying device 7, making the transfer process smoother. When the lower mold 10 carrying the product material flows from the conveyor belt of the previous process position to the lifting and tilting unloading platform 53, the lower surface of the lower mold 10 is supported by the second guide wheel 520. Then, the second guide motor 517 is started to supply power to the second guide wheel 520 through the second drive sprocket 518 and the second driven sprocket 519, so that the second guide wheel 520 can completely transport the lower mold 10 to the lifting and tilting unloading platform 53. When it is necessary to transport the lower mold 10 from the lifting and tilting unloading platform 53 to the lower conveyor device 7, it is only necessary to reverse the second guide motor 517 by controlling the program, which greatly improves the transfer efficiency.

[0110] Specifically, the lifting and tilting unloading platform 53 has a positioning block 521 at one end near its rotation connection point, i.e., in the tilting direction. This block is used to block the path of the lower mold 10. When the front end of the lower mold 10 abuts against the positioning block 521, the through hole reserved on the lower mold 10 corresponds exactly to the ejector pin on the unloading ejector plate 54, making it easy for the ejector pin to pass through the through hole and push the product seed material bonded to the lower mold 10 off.

[0111] Specifically, the unloading frame 51 is equipped with multiple light strips 522 and cameras 523, all of which face the lower mold 10 mounted above the lifting and tilting unloading platform 53. The cameras 523 can transmit the captured video to the control terminal in real time, allowing operators to monitor the unloading process and the condition of the raw material.

[0112] Please see Figure 14The cleaning device 8 includes a cleaning assembly located below the hot pressing device 3. This assembly is situated below and separated from the lower hot pressing plate 34. The cleaning assembly includes a cleaning chamber 81 with openings at both its front and rear ends for the lower mold 10 to pass through. A lower conveying device 7 is placed within the cleaning chamber 81. This lower conveying device 7 can be any commercially available conveying mechanism capable of achieving a conveying effect, used to support and transport the returning lower mold 10. The cleaning chamber 81 also includes a cleaning nozzle 82 facing the upper surface of the lower mold 10. The lower conveying device 7 receives the lower mold 10 after the unloading process and transports it into the cleaning chamber 81, where the cleaning nozzle 82 washes and cleans the lower mold 10.

[0113] It is worth noting that the lower mold 10 and the upper mold 9 are not limited to the structure proposed in this invention, and any upper and lower structure mold suitable for processing and shaping granular products can also be used.

[0114] The product seed material is an ellipsoidal high-cellulose lignin product seed material.

[0115] The present invention also provides a rapid and precise forming process, applied to a rapid and precise forming system, comprising the following steps:

[0116] S1. Loading Seeds: The washed and processed product seeds are placed in the feeding hopper 12 by manual labor or conveyor belt. Then, the product seeds can be automatically loaded onto the lower mold 10 by the feeding device 1.

[0117] S2. Preheating: Start the upper conveyor 6 to transport the lower mold 10 and the product seed material into the heating device 2 to preheat the lower mold 10 and the product seed material. The preheating temperature range is 80℃-160℃.

[0118] S3. Hot Pressing: The upper conveying device 6 is activated to transport the lower mold 10 containing the product material to the hot pressing device 3 and make it contact the lower hot pressing plate 34. The first press 32 is activated, and the upper mold 9 moves downward to cooperate with the lower mold 10 to extrude and hold pressure on the product material. The upper hot pressing plate 33 and the lower hot pressing plate 34 of the first press 32 are continuously heated. The heating method of the upper and lower plates is selected from hot water, steam, and electric heating, with a temperature range of 85℃-160℃. The hot pressing process is divided into two stages. The first stage: the upper mold 9 is pressed down to the first position, which is 0.5-2mm higher than the minimum limit position between the upper mold 9 and the lower mold 10. The upper mold 9 holds pressure at the first position for 1-10 seconds. The second stage: the upper mold 9 continues to press down to the minimum limit position between the upper mold 9 and the lower mold 10. After holding pressure for 30-150 seconds, the upper plate and the upper mold 9 rise back to the initial position. After the hot pressing is completed, the upper mold 9 moves upward.

[0119] S4. Cold Pressing: The upper conveyor 6 is activated to transport the lower mold 10, which has completed hot pressing, to the cold press and bring it into contact with the lower cold press plate 44.
