[0007] By adopting the above technical solution, the material enters the steaming chamber after the feeding hopper adjusts the falling direction. When the material enters the steaming chamber, the third telescopic member disengages between the feeding hopper and the steaming chamber, and at the same time, the first telescopic member is inserted into the first through hole. When the steaming chamber receives the material, the third telescopic member is inserted between the feeding hopper and the steaming chamber, making the steaming chamber form a closed space, and the material is supported by the air-permeable plate.

[0008] The gas in the steam chamber passes through the air-permeable plate from bottom to top to steam the material, making the surface of the material soften and reducing the degree of fragmentation during the subsequent pressing process; when the material is steamed, the first telescopic member disengages from the first through hole, and at the same time, the second telescopic member pushes the material into the first through hole. By using the vertical setting of the first through hole, the material can fall into the mold cavity under the action of gravity. At the same time, in order to prevent some materials from sticking to the inner wall of the first through hole, the first telescopic member is controlled to be inserted into the first through hole to scrape the residual material on the inner wall of the first through hole into the mold cavity synchronously;

[0009] When the material flows into the mold cavity, the fourth telescopic member moves horizontally above the opening of the mold cavity under the action of the linear guide rail. At the same time, the fourth telescopic member moves up and down to control the jaw cylinder to extend into the mold cavity. By controlling the grasping and releasing actions of the jaw cylinder, the leveling of the material is realized, which is convenient for better realizing the pressing operation in the subsequent process;

[0010] For the leveled material, the fifth telescopic member drives the mold cavity to move below the upper mold, and the sixth telescopic member controls the upper mold to abut against the surface of the material in the mold cavity, and then continuously presses down to press and form the material.

[0011] Optionally, it further includes a feeding tray and a weighing hopper. The feeding tray feeds materials towards the weighing hopper. A switch plate is hinged at the discharging end of the weighing hopper, and a seventh telescopic member is connected to the switch plate. The seventh telescopic member drives the switch plate to open or close the discharging end of the weighing hopper, and the weighing hopper feeds materials towards the feeding hopper.

[0012] By adopting the above technical solution, by using the weighing hopper, when the feeding tray is about to convey materials to the weighing hopper, the switch plate closes the weighing hopper until the weighing hopper is full to realize the quantitative control of the materials; after the weighing hopper is full, the seventh telescopic member drives the switch plate to disengage from the discharging end of the weighing hopper, making the discharging end of the weighing hopper in an open state. At this time, the quantitatively controlled materials are conveyed into the feeding hopper, and at the same time, the feeding hopper is used to adjust the falling direction to convey the materials into the steaming chamber. With this structure, the quantitative processing of the materials can be realized, and the process quality consistency is good.

[0013] Optionally, the steam chamber is externally connected to a water vapor separation device, and the position distribution of the first telescopic member, the second telescopic member and the third telescopic member is utilized to form a closed structure in the steaming chamber.

[0014] By adopting the above technical scheme, water vapor can be transformed into water vapor by using the water vapor separation device, and the water vapor enters the steam chamber. The position distribution of the first telescopic part, the second telescopic part and the third telescopic part makes the steaming chamber closed, and the water vapor is kept at a constant temperature to continuously steam the material, and the process processing effect is good.

[0015] Optionally, it also includes a support seat, which is located below the steaming chamber, the guide rail is installed on the support seat, the mounting seat has a second through hole, and a lower mold is provided in the mold cavity. When the mold cavity is placed on the mounting seat, the lower mold abuts against the second through hole.

[0016] By adopting the above technical solution, the second through hole on the mounting seat is utilized, and the lower mold is simultaneously abutted against the second through hole. When the material in the mold cavity is compacted, the lower mold can be lifted toward the opening along the bottom of the mold cavity through the second through hole, so that the compacted material can be separated from the mold cavity, facilitating the material collection process.

[0017] Optionally, the clamping cylinder is located on the side of the mold cavity. When the material falls into the mold cavity block from the first through hole, the clamping cylinder extends into the mold cavity under the control of the linear guide rail and the fourth telescopic member to level the material in the mold cavity.

[0018] By adopting the above technical solution, when the material is stored in the mold cavity, the linear guide rail controls the fourth telescopic part to be located at the side of the mold cavity, and at the same time cooperates with the lifting operation of the fourth telescopic part, so that the clamping cylinder is located at the opening of the mold cavity, and at the same time extends into the mold cavity to abut on the surface of the material, thereby realizing leveling operation on the material in the mold cavity. The clamping cylinder is used to level the material, so that the material will not have one high and one low in the mold cavity, or accumulate in one place, which is convenient for subsequent compaction and molding, and the structure is uniform, and the appearance is good.

[0019] Optionally, the support seat is provided with a placement cavity for placing the inner fly, and the manipulator module further includes an eighth telescopic member, the eighth telescopic member is connected to a suction cup, the eighth telescopic member moves in the Y-axis and is connected to the linear guide rail, and when the material in the mold cavity is leveled, the eighth telescopic member drives the suction cup to adsorb the inner fly in the placement cavity and place it on the material in the mold cavity.

[0020] By adopting the above technical solution, the inner fly is a mark, which is placed in the placement cavity. When the material is leveled, the linear guide drives the eighth telescopic part to run into the placement cavity first, and uses the suction cup to pre-suck up the inner fly. Then, under the control of the linear guide, the eighth telescopic part is moved to the opening of the mold cavity.

[0021] Optionally, a third through hole is provided on the support seat, and a ninth telescopic member is provided below the third through hole. The ninth telescopic member passes through the third through hole to perform lifting motion. When the sixth telescopic member drives the upper mold to extrude the material in the mold cavity, the fifth telescopic member pushes the mounting seat to connect the second through hole with the third through hole, and the ninth telescopic member passes through the third through hole and the second through hole in turn to lift the lower mold, so that the material is separated from the mold cavity.

[0022] By adopting the above technical solution, after the material in the mold cavity is extruded and formed, the ninth telescopic part passes through the third through hole and the second through hole respectively and abuts against the lower mold, and then the ninth telescopic part drives the lower mold to lift, so that the material can be separated from the mold cavity, completing the demolding process. Utilizing this structure, the material can be taken out conveniently and quickly.

[0023] Optionally, the robot module further includes a tenth telescopic member, which moves in the Y-axis and is connected to the linear guide rail. The tenth telescopic member is also connected to a connecting plate, and telescopic claws are respectively provided at both ends of the connecting plate. The two telescopic claws are arranged opposite to each other. When the material leaves the mold cavity, the two telescopic claws can grab and deliver the material.

[0024] By adopting the above technical solution, when the material is ready to be taken out of the mold cavity, the linear guide rail controls the tenth telescopic member to be located at the top of the mold cavity opening. When the material is pushed out of the mold cavity, the tenth telescopic member drives the telescopic claw to move down to the side area of the material. At the same time, the two telescopic claws move relative to each other to achieve clamping of the side of the material. The tenth telescopic member simultaneously drives the telescopic claw to move upward to complete the grabbing and delivery of the material.

[0025] Optionally, the number of the manipulator modules and the pressurizing modules is the same, and a plurality of pressurizing modules can be provided according to the time required for molding a single material.

[0026] By adopting the above technical solution, each pressurizing module corresponds to a robot module to operate and complete the corresponding leveling, inner fly placement and compaction molding processes. According to the molding time required for each material, multiple pressurizing modules and robot modules can be set to alternately operate production, thereby effectively improving production efficiency.

[0027] Second aspect, a processing method of an automatic pressed tea device provided by the present application, based on the above automatic pressed tea device, includes the following steps:

[0028] S1. The third telescopic member disengages between the material receiving hopper and the steaming chamber, and a quantified amount of material naturally falls through the material receiving hopper into the steaming chamber to prepare for tea steaming.

[0029] S2. After the steaming chamber receives the material, the third telescopic member is inserted between the material receiving hopper and the steaming chamber. At the same time, the first telescopic member is inserted into the first through hole, and the water vapor in the steam cavity passes through the air-permeable plate to soften the material.

[0030] S3. After the material is softened, the first telescopic member disengages from the first through hole, and the second telescopic member pushes the softened material into the first through hole.

[0031] S4. The material in the first through hole falls into the mold cavity, and the clamping jaw cylinder levels the material in the mold cavity.

[0032] S5. The sixth telescopic member drives the upper mold to extrude the material in the mold cavity to achieve tight pressing and forming.

[0033] By adopting the above technical solutions, each station does not require manual participation in production. When all stations operate in a fully automated manner, the production efficiency is high, and the production cycle is effectively reduced.

[0034] In summary, the present application includes at least one of the following beneficial effects:

[0035] 1.

[0036] 2. Using the weighing hopper, when the feeding tray is about to convey material to the weighing hopper, the switch plate closes the weighing hopper until the weighing hopper is full to achieve quantitative control of the material; after the weighing hopper is full, the seventh telescopic member drives the switch plate to disengage from the discharge end of the weighing hopper, making the discharge end of the weighing hopper in an open state. At this time, the quantified amount of material is conveyed into the material receiving hopper. At the same time, the material receiving hopper is used to adjust the falling direction of the material and convey the material into the steaming chamber. With this structure, quantitative processing of the material can be achieved, and the process quality consistency is good.

[0049] The following combines the attached Figure 1-7 to further elaborate on this application in detail.

[0050] Example 1: An automatic pressed tea device, referring to Figure 1 , includes a feeding tray 1, a weighing hopper 2, a receiving hopper 3, a steaming chamber 4, a mechanical module and a pressing module 6. The feeding tray 1 conveys materials towards the weighing hopper 2. The weighing hopper 2 measures the quantity of the materials. After the quantity measurement is completed, the materials are conveyed into the receiving hopper 3. The receiving hopper 3 is used to adjust the falling direction of the materials and then convey them to the steaming chamber 4. The steaming chamber 4 softens the materials by steaming. The softened materials are leveled and the inner flyer is placed by the mechanical module. Finally, the pressing module 6 presses and forms the materials.

[0051] Referring to Figure 2 , specifically, the feeding tray 1 uses automatic vibrating feeding. The weighing hopper 2 is located below the feeding tray 1, and the receiving hopper 3 is located below the weighing hopper 2. When the feeding tray 1 discharges materials, they fall freely into the weighing hopper 2. There are two feeding trays 1 and two weighing hoppers 2, and they are in one-to-one correspondence. The two feeding trays 1 carry out the quantity measurement of the materials simultaneously or alternately. The bottom of the weighing hopper 2 is the discharging end, and a switch plate 21 is arranged at the discharging end. There is a pair of switch plates 21 on each weighing hopper 2. The switch plates 21 are arranged oppositely and are respectively hinged to the weighing hopper 2 through hinges. The two switch plates 21 are jointly connected to a seventh telescopic member 23 by a hinge bar 22. The seventh telescopic member 23 is fixed to the weighing hopper 2 and expands and contracts along the discharging end direction of the weighing hopper 2. Before filling the materials, the seventh telescopic member 23 drives the switch plate 21 to close the discharging end of the weighing hopper 2; when the materials are filled to the full amount in the weighing hopper 2, the seventh telescopic member 23 drives the switch plate 21 to disengage from the discharging end, making the discharging end of the weighing hopper 2 in an open state. At this time, the quantitatively measured materials flow into the receiving hopper 3.

[0052] Referring to Figure 3 and Figure 4The receiving hopper 3 temporarily circulates the materials, which is convenient for unified control of the flow direction of the materials. The receiving hopper 3 is located directly above the steaming chamber 4, and the two are interconnected. A third telescopic member 45 is movably inserted between the receiving hopper 3 and the steaming chamber 4. The third telescopic member 45 is used to control the connection or separation between the receiving hopper 3 and the steaming chamber 4. A layer of air permeable plate 41 is arranged inside the steaming chamber 4. A plurality of air permeable holes are arranged in an array on the air permeable plate 41. A steam cavity 42 is arranged at the bottom of the air permeable plate 41. When the third telescopic member 45 is separated from the receiving hopper 3 and the steaming chamber 4, the materials in the receiving hopper 3 are transported into the steaming chamber 4 and supported by the air permeable plate 41.

[0053] A first through hole 43 is vertically provided on one side of the air permeable plate 41 of the steaming chamber 4, and a first telescopic member 431 is movably inserted in the first through hole 43. A second telescopic member 44 is provided on the other side of the air permeable plate 41 of the steaming chamber 4, and the second telescopic member 44 abuts against the air permeable plate 41. The second telescopic member 44 is located on the opposite side of the first telescopic member 431, and telescopes left and right toward the position of the first through hole 43. When the steaming chamber 4 receives the material, the third telescopic member 45 is inserted between the material receiving hopper 3 and the steaming chamber 4, so that the passage between the material receiving hopper 3 and the steaming chamber 4 is isolated, and the steaming chamber 4 utilizes the position distribution of the first telescopic member 431, the second telescopic member 44 and the third telescopic member 45 to form a closed structure.

[0054] In some embodiments, the steam chamber 42 is externally connected to a water vapor separation device (not shown in the figure), and the liquid is vaporized into water vapor by the water vapor separation device, and the water vapor enters the steam chamber 42. The gas in the steam chamber 42 passes through the air permeable plate 41 from bottom to top, so as to steam the material, soften the surface of the material, and reduce the degree of fragmentation in the subsequent pressing process. When the material is steamed, the first telescopic member 431 is telescoped upward to separate from the first through hole 43, and the second telescopic member 44 pushes the material into the first through hole 43. The vertical setting of the first through hole 43 allows the material to be transported downward by free fall. In order to avoid part of the material from adhering to the inside of the first through hole 43, when the second telescopic member 44 completes pushing the material, the first telescopic member 431 is controlled to be inserted into the first through hole 43 again, and the residual material in the first through hole 43 is scraped off synchronously.

[0055] See also Figure 5 and Figure 6, the manipulator module 5 and the pressurizing module 6 are installed on the support base 7, and the support base 7 is located below the steaming chamber 4. The pressurizing module 6 includes guide rails 61, a mold cavity 63, a fifth telescopic member 64 and a sixth telescopic member 65. There are two guide rails 61 arranged in parallel on the support base 7. A mounting seat 62 is slidably connected to the guide rails 61. The mold cavity 63 is placed on the mounting seat 62. The fifth telescopic member 64 is installed on the support base 7, and its driving end is connected to the mounting seat 62. The fifth telescopic member 64 is used to drive the mounting seat 62 to slide along the guide rails 61. The fixed end of the sixth telescopic member 65 is fixed to the upper part of the support base 7 through a support bar 71 and is perpendicular to the fifth telescopic member 64.

[0056] When the material freely falls from the first through hole 43 (marked in Figure 4 ), the fifth telescopic member 64 drives the mounting seat 62 to slide to the discharge end of the first through hole 43, and the mold cavity 63 is directly opposite to the first through hole 43. Thus, the material flows from the first through hole 43 into the mold cavity 63.

[0057] In some embodiments, the manipulator module 5 includes a linear guide rail 51 and a fourth telescopic member 52. The linear guide rail 51 is installed on the support bar 71. The fourth telescopic member 52 is connected to the linear guide rail 51 through a connecting plate 511. The linear guide rail 51 drives the fourth telescopic member 52 to move along the X-axis. The fourth telescopic member 52 can move up and down, performing a Y-axis movement. The driving end of the fourth telescopic member 52 is connected to a jaw cylinder 521. The jaw cylinder 521 can perform grasping or releasing actions. It should be noted that the jaw cylinder 521 is the application of an existing structure, and the structural principle thereof will not be specifically described in this application.

[0058] In this embodiment, the linear guide rail is driven electromagnetically. The structure here can also be set to be driven by a cylinder, a belt or a gear row. No specific limitation is made in this embodiment.

[0059] When the mold cavity 63 is filled with the material, the fourth telescopic member 52 moves horizontally above the opening of the mold cavity 63 under the action of the linear guide rail 51. At the same time, the fourth telescopic member 52 moves up and down to control the jaw cylinder 521 to extend into the mold cavity 63. By controlling the jaw cylinder 521 to repeatedly perform grasping or releasing actions on the material, the leveling of the material surface is realized, which is convenient for the material to be evenly distributed in the mold cavity 63, so that the material will not produce a phenomenon of being high or low or concentrated in one place in the mold cavity 63, facilitating the uniform structure during subsequent pressing and forming.

[0060] In some embodiments, a placement cavity 72 for placing the inner flyer is further provided on the support base 7. The inner flyer is an information identifier of a product, including information such as trademark patterns, production information, and shelf life. The manipulator module 5 further includes an eighth telescopic member 53. The eighth telescopic member 53 is connected to the linear guide 51 through a connecting plate 511, and a suction cup 531 is connected to the driving end. A negative-pressure air is connected to the suction cup 531. When an object abuts against the suction cup 531, it can be sucked and will not fall. The eighth telescopic member 53 also makes a Y-axis lifting movement. After the material in the mold cavity 63 is leveled, the linear guide 51 drives the eighth telescopic member 53 to first run into the placement cavity 72, and uses the suction cup 531 to pre-lift the inner flyer. Then, under the control of the linear guide 51, the eighth telescopic member 53 is run to the opening of the mold cavity 63. At this time, under the lifting of the eighth telescopic member 53, the suction cup 531 drives the inner flyer to extend into the mold cavity 63, completing the placement of the inner flyer on the material.

[0061] After the inner flyer is placed, the fifth telescopic member 64 drives the mounting seat 62 to move towards the original position, so that the opening of the mold cavity 63 faces the bottom of the sixth telescopic member 65. In this embodiment, an upper mold 651 is provided on the driving end of the sixth telescopic member 65. The sixth telescopic member 65 drives the upper mold 651 to stretch in and out of the opening of the mold cavity 63 and abut against the material, so that the upper mold 651 and the lower mold 6321 are pressed against each other in the mold cavity 63, causing the material to form the shape of the mold.

[0062] See Figure 7 , the mounting seat 62 has a second through hole 621, and a lower mold 631 is provided in the mold cavity 63. The lower mold 631 can slide up and down along the inner wall of the mold cavity 63. When the mold cavity 63 is placed on the mounting seat 62, the lower mold 631 abuts against the second through hole 621 under the influence of gravity, and the outer diameter of the lower mold 631 is larger than the inner diameter of the second through hole 621.

[0063] See Figure 5 And Figure 7 , a third through hole 73 is opened on the support base 7. The third through hole 73 is vertically opened and is parallel to the second through hole 621. A ninth telescopic member 74 is provided below the third through hole 73. The fixed end of the ninth telescopic member 74 is installed on the support base 7. The driving end of the ninth telescopic member 74 makes a lifting movement upward through the third through hole 73. After the sixth telescopic member 65 drives the upper mold 651 to extrude and form the material in the mold cavity 63, the fifth telescopic member 64 pushes the mounting seat 62, so that the second through hole 621 and the third through hole 73 are vertically connected. At this time, the ninth telescopic member 74 passes through the third through hole 73 and the second through hole 621 in sequence, and the driving end of the ninth telescopic member 74 abuts against the bottom of the lower mold 631. As the ninth telescopic member 74 rises successively, it drives the lower mold 631 to synchronously lift along the inside of the mold cavity 63 until the material breaks away from the mold cavity 63 and leaks out.

[0064] See Figure 6 The manipulator module 5 further includes a tenth telescopic member 54. The tenth telescopic member 54 is connected to the linear guide rail 51. The tenth telescopic member 54 is connected to the linear guide rail 51 through a connecting plate 511. The linear guide rail 51 also drives the tenth telescopic member 54 to move along the X-axis. The tenth telescopic member 54 moves along the Y-axis. The driving end of the tenth telescopic member 54 is connected to a connecting plate 55. The connection point is located at the center of the connecting plate 55. Telescopic jaws 551 are respectively arranged at both ends of the connecting plate 55. A cylinder is arranged on the telescopic jaws 551. The telescopic jaws 551 are arranged oppositely. The cylinder drives the jaws to move in opposite directions. When the material is ready to be taken out of the mold cavity 63, the linear guide rail 51 controls the tenth telescopic member 54 to be located at the top of the opening of the mold cavity 63. When the material is pushed out of the mold cavity 63, the tenth telescopic member 54 drives the telescopic jaws 551 to move down to the side area of the material. At the same time, the two telescopic jaws 551 move relatively to realize the clamping of the side of the material. The tenth telescopic member 54 synchronously drives the telescopic jaws 551 to move up to complete the grasping and placing of the material.

[0065] It should be noted that in this embodiment, the telescopic members are all driven by linear telescopic cylinders, with fast action efficiency, simple operation and good application effect.

[0066] In some embodiments, the number of the manipulator module 5 and the pressing module 6 is the same. The pressing module 6 can be set in multiple numbers according to the time required for the forming of a single material. Each pressing module 6 corresponds to a manipulator module 5 to complete the corresponding leveling, placing of inner flying and pressing and forming processes. According to the forming time required for each material, multiple pressing modules 6 and manipulator modules 5 can be set to operate alternately to effectively improve the production efficiency.

[0067] In this embodiment, two manipulator modules 5 and two pressing modules 6 are respectively provided. Each manipulator module 5 cooperates with a pressing module 6 for auxiliary operation. The left and right groups of molds operate symmetrically and alternately, shortening the pressure maintaining and shaping time of the mold cavity 63, and alternately reaching the first through hole 43 in turn to receive materials and continue pressing, making full use of the shaping time of the mold cavity 63 and the corresponding process time to improve the production efficiency.

[0068] It should be noted that this application can not only perform the automatic processing process of forming tea cakes from tea leaves, but also perform the corresponding automatic processing and forming operations on forming tea bricks from tea leaves or for kelp, Chinese herbal medicines, etc.

[0069] The mold cavity 63 can be replaced according to the shape of the pressed tea. Except for the circular structure of the tea cake designed in this application, it can be designed into the outer shape of a tea brick such as a square or a rectangle, and the cross-sectional shape of the corresponding first through hole 43 is replaced. In this embodiment, the processed articles are not specifically limited, as long as they can be adapted to this device.

[0070] The implementation principle of the embodiment of this application is as follows: After the material adjusts the falling direction through the receiving hopper 3 and enters the steaming chamber 4, when the material enters the steaming chamber 4, the third telescopic member 45 disengages between the receiving hopper 3 and the steaming chamber 4, and at the same time, the first telescopic member 431 is inserted into the first through hole 43. When the steaming chamber 4 has received the material, the third telescopic member 45 is inserted between the receiving hopper 3 and the steaming chamber 4, making the steaming chamber 4 form a closed space, and the material is supported by the air-permeable plate 41.

[0071] The gas in the steam chamber 42 passes through the air-permeable plate 41 from bottom to top to steam the material, making the surface of the material soften and reducing the degree of fragmentation during the subsequent pressing process; when the material is steamed, the first telescopic member 431 disengages from the first through hole 43, and at the same time, the second telescopic member 44 pushes the material into the first through hole 43. With the vertical setting of the first through hole 43, the material can fall into the mold cavity 63 under the action of gravity. At the same time, in order to prevent some material from adhering to the inner wall of the first through hole 43, the first telescopic member 431 is inserted into the first through hole 43 to scrape the residual material on the inner wall of the first through hole 43 into the mold cavity 63 synchronously;

[0072] When the material flows into the mold cavity 63, the fourth telescopic member 52 moves horizontally above the opening of the mold cavity 63 under the action of the linear guide 51. At the same time, the fourth telescopic member 52 moves up and down to control the gripper cylinder 521 to extend into the mold cavity 63. By controlling the grasping and releasing actions of the gripper cylinder 521, the leveling of the material is realized, which is convenient for better realizing the pressing operation in the subsequent process;

[0073] For the leveled material, the fifth telescopic member 64 drives the mold cavity 63 to move below the upper mold 651, and the sixth telescopic member 65 controls the upper mold 651 to abut against the surface of the material in the mold cavity 63, and then continuously presses down to press and form the material. By using the automatic operation of each of the above processes, manual participation in production or the operation of corresponding auxiliary machines is not required, the production efficiency is high, and the duration of the process production cycle is effectively reduced.

[0074] Embodiment 2: A processing method of an automatic pressed tea device, based on the aforementioned automatic pressed tea device, includes the following steps:

[0075] S1. In the initial state, the material is fed into the feeding tray 1 and falls freely from the feeding tray 1 into the weighing hopper 2;

[0076] S2. The weighing hopper 2 is quantitatively filled. When it reaches the weight, the feeding tray 1 stops working. The left and right weighing hoppers 2 operate simultaneously or alternately. The switch plate 21 at the bottom discharge end of the first filled weighing hopper 2 (i.e., reaching the weight) is opened first, and the material falls freely from the weighing hopper 2 to the receiving hopper 3, and after passing through the receiving hopper 3 to adjust the falling direction, it enters the steaming chamber 4;

[0077] S3. The third telescopic member 45 is opened so that the material receiving hopper 3 communicates with the steaming chamber 4, and the steaming chamber 4 receives the materials dropped from the discharge hopper.

[0078] S4. After the steaming chamber 4 receives the materials, the third telescopic member 45 is closed to block the communication between the material receiving hopper 3 and the steaming chamber 4. At this time, the water vapor separation device is opened, and water vapor enters the steam chamber 42 to soften the materials, so that the materials are not easily broken during pressing. After being softened, the contained substances can be partially extruded to the surface during pressing, promoting the adhesion of the materials into a mass, or different shapes such as blocks, round cakes, square bricks, and chocolates.

[0079] S5. The first telescopic member 431 disengages from the first through hole 43, and the first through hole 43 communicates with the mold cavity 63. The softened materials are pushed by the second telescopic member 44 and freely fall into the mold cavity 63 through the first through hole 43 for collection.

[0080] S6. The jaw cylinder 521 is located at the side of the mold cavity 63 that has received the materials, and the jaw cylinder 521 extends into the mold cavity 63 to level the materials, so that the materials are evenly distributed in all corners of the mold cavity 63.

[0081] S7. The suction cup 531 is displaced to the placement cavity 72 for placing the inner flyer, sucks the inner flyer on the suction cup 531, and the suction cup 531 extends into the mold cavity 63 under the control of the eighth telescopic member 53 to place the inner flyer on the materials.

[0082] S8. The materials in the mold cavity 63 that have been leveled and had the inner flyer placed are conveyed below the upper mold 651, and the sixth telescopic member 65 drives the upper mold 651 to extend and retract into the opening of the mold cavity 63 and abut against the materials to achieve tight pressing and forming.

[0083] S9. After the materials are formed, the lower mold 631 on the mold cavity 63 is aligned with the third through hole 73, and the ninth telescopic member 74 passes through the third through hole 73 and abuts against the lower mold 631 to lift the lower mold 631, and at the same time, the materials are separated from the mold cavity 63.

[0084] S10. The telescopic jaw 551 abuts against the side of the materials to achieve grasping and placing of the materials.

[0085] The embodiments of this specific implementation manner are all preferred embodiments of this application, and do not limit the protection scope of this application accordingly. The same components are denoted by the same reference numerals. Therefore, all equivalent changes made according to the structure, shape, and principle of this application should be covered within the protection scope of this application.
