DETAILED DESCRIPTION

[0035] The technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application.

[0036] Please refer to Figures 1 to 12 The tea-making mold provided in the embodiment of the present application includes a lower mold base 100, a lower mold 200, two guide pillars 300, an upper mold base 400, an upper mold 500 and a guide module 600.

[0037] refer to Figure 1 and Figure 7 , wherein the two guide pillars 300 are fixed to the lower die base 100 in parallel and at intervals, and the lower die 200 is disposed on the lower die base 100 and is located between the two guide pillars 300. Those skilled in the art can understand that the lower die 200 can be fixedly disposed on the lower die base 100, or the lower die 200 can be movably disposed on the lower die base 100.

[0038] The lower mold 200 is provided with a lower mold cavity 210. The upper mold base 400 is slidably connected to the two guide pillars 300, and the upper mold 500 is fixedly connected to the upper mold base 400, and the upper mold 500 is located between the two guide pillars 300. Specifically, the tea-making mold also includes two linear bearings 900, and the two linear bearings 900 are respectively sleeved on the two guide pillars 300, and the two ends of the upper mold base 400 are slidably connected to the two guide pillars 300 through the two linear bearings 900. That is, the two ends of the upper mold base 400 are respectively fixedly connected to the two linear bearings 900, and the two linear bearings 900 are then respectively slidably sleeved on the two guide pillars 300. It can be understood by those skilled in the art that the upper mold base 400 and the linear bearings 900 can be fixed by fasteners such as bolts, which is a well-known technology in the art and will not be repeated here. In the embodiment of the present application, by providing a linear bearing 900, the friction force of the upper mold base 400 sliding on the guide column 300 can be reduced, thereby facilitating the up and down movement of the upper mold base 400.

[0039] Please continue to refer to Figure 1 and Figure 7Furthermore, the tea-making mold further includes a first driving device and a cam bearing follower 910. The fixed end of the first driving device is fixed to the mold frame (not shown in the figure), and the driving end of the first driving device is drivingly connected to the cam bearing follower 910. The cam bearing follower 910 is connected to the end of the upper mold base 400 away from the upper mold 500. Under the drive of the first driving device, the cam bearing follower 910 can drive the upper mold base 400 to move along the two guide pillars 300, thereby providing power for the movement of the upper mold 500.

[0040] Please continue to refer to Figure 1 and Figure 7 Further, the guide module 600 includes a material guide block 610, a first push block 620 and a second push block 630. The material guide block 610 is provided with a material guide channel 611 penetrating along the first direction. The bottom of the material guide block 610 is provided with a lower opening, and the top of the material guide block 610 is provided with an upper opening, and both the upper opening and the lower opening are connected to the material guide channel 611. It can be understood by those skilled in the art that the upper opening can be consistent with the length of the material guide channel 611, the lower opening can be opened only on one side close to the lower mold cavity 210, and the size of the lower opening can be adapted to the lower mold cavity 210. Generally, the size of the lower opening can be consistent with the opening size of the lower mold cavity 210, so that the tea leaves can easily enter the lower mold cavity 210 from the lower opening, and the tea leaves can be prevented from falling on the surface of the lower mold 200.

[0041] Please continue to refer to Figure 1 and Figure 7 , the guide block 610 is slidably connected to the lower die base 100. Specifically, a first guide plate (not shown in the figure) can be provided on the lower die base 100, and the bottom of the guide block 610 is slidably provided on the first guide plate, so as to facilitate the movement of the guide block 610. Obviously, in the embodiment of the present application, a second driving device is also provided to drive the guide block 610 to slide. The installation and connection methods of the first guide plate and the second driving device are both existing technologies in the art and will not be described in detail in the embodiment of the present application.

[0042] Please refer to Figure 2 , Figure 3 , Figure 8 and Fig. 9, the first push block 620 is slidably connected to the material guide channel 611, and the second push block 630 is slidably connected to the lower die base 100; the first push block 620 and the second push block 630 are respectively located on both sides of the lower die cavity 210. The material guide block 610 can move along the lower die base 100 so that the lower opening is connected to the lower die cavity 210, the first push block 620 and the second push block 630 can approach each other and enclose a pre-pressing channel 640 in the material guide channel 611, that is, the first push block 620 can move toward the second push block 630, the second push block 630 can move toward the first push block 620 into the material guide channel 611, and enclose the first push block 620 to form a pre-pressing channel 640. Along the direction from the upper die base 400 to the lower die base 100, the upper opening, the pre-pressing channel 640, the lower opening and the lower die cavity 210 are connected in sequence; the first direction is the length direction of the material guide block 610, such as Figure 1 The second direction is the direction from the upper mold base 400 to the lower mold base 100, and the first direction is perpendicular to the second direction. Figure 1 Y direction shown in .

[0043] Please continue to refer to Figure 1 , Figure 2 , Figure 3 , Figure 7 , Figure 8 and Fig. 9 Specifically, the lower die base 100 may also be provided with a second guide plate (not shown in the figure) for the second push block 630 to slide, and a third driving device for providing power for the movement of the second push block 630. It can be understood by those skilled in the art that the upper surface of the second guide plate and the bottom wall surface of the material guide channel 611 are on the same plane, so that the second push block 630 can be easily pushed from the second guide plate to the material guide channel 611 by the third driving device. It can be understood by those skilled in the art that the initial position of the material guide block 610 is far away from the lower die cavity 210, that is, the initial position of the material guide block 610 does not overlap with the lower die cavity 210 in the second direction, and the initial position of the first push block 620 is located at one end of the material guide channel 611 far away from the second push block 630.

[0044] Please refer to Figure 4 and Fig.10 The upper die seat 400 can drive the upper die 500 to slide along the two guide pillars 300 so that the upper die 500 passes through the pre-pressing channel 640 and closes with the lower die 200.

[0045] Please refer to Figure 1 and Figure 7In the embodiment of the present application, when it is necessary to press the tea leaves, the tea leaves are first added to the material guide channel 611 from the upper opening of the material guide channel 611. Since the material guide block 610 is far away from the upper mold 500 at this time, when adding tea leaves to the material guide channel 611 of the material guide block 610, it will not be disturbed by the upper mold 500, and since the upper opening of the material guide channel 611 can be designed to be larger, it can be further convenient to add tea leaves to the material guide channel 611. In the embodiment of the present application, since the initial position of the material guide block 610 is far away from the lower mold cavity 210, and the upper opening of the material guide channel 611 can be designed as needed, therefore, the embodiment of the present application can also be provided with an automatic feeding device for use in conjunction with the material guide channel 611, thereby further increasing the convenience of tea leaves delivery. The automatic feeding device can be set by those skilled in the art as needed, and the embodiment of the present application will not be repeated. It can be understood by those skilled in the art that after the tea leaves are delivered to the material guide channel 611, the tea leaves are located on the side of the first push block 620 close to the second push block 630.

[0046] Please refer to Figure 2 and Figure 8 After the tea leaves are put in, the material guide block 610 is first moved to make the lower opening of the material guide channel 611 connected to the lower mold cavity 210. At this time, the second push block 630 is moved to make the second push block 630 block the opening of the material guide channel 611 away from the side of the first push block 620. Those skilled in the art can understand that, at this time, there is still a gap between the second push block 630 and the lower mold cavity 210. Then, the first push block 620 is pushed to push the tea leaves in the material guide channel 611 toward the second push block 630 until the edge of the first push block 620 close to the second push block 630 coincides with the opening edge of the lower mold cavity 210. At this time, the tea leaves are located above the lower mold cavity 210 and in the material guide channel 611 between the lower mold cavity 210 and the second push block 630. Then, the second push block 630 is pushed again to push the tea leaves toward the first push block 620, and the second push block 630 and the first push block 620 are surrounded to form a pre-pressing channel 640. At this time, the tea leaves are confined in the pre-pressing channel 640. Figure 3 and Fig. 9 shown.

[0047] It can be understood by those skilled in the art that, in the embodiment of the present application, the tea leaves are first pushed from the side of the first push block 620 to the side of the second push block 630, and then pushed from the side of the second push block 630 to the side of the first push block 620, so that the tea leaves are finally located in the pre-pressing channel 640. By using a specific order of pushing the tea leaves, it can be ensured that the corners of the pressed tea leaves 10 with corners are pressed tightly during the pressing process, and the corners of the pressed tea leaves 10 with corners are prevented from being loose or missing. Of course, for pressed tea leaves 10 without corners, the order of pushing the tea leaves can be adjusted. For example, for a spherical tea leaf, the second push block 630 can be first pushed to align the second push block 630 with the edge of the lower mold cavity 210, and then the first push block 620 can be pushed to form a pre-pressing channel 640 with the second push block 620, and no specific restrictions are made.

[0048] Please refer to Figure 4 and Fig.10 In the embodiment of the present application, after the tea leaves are concentrated in the pre-pressing channel 640, the upper mold 500 is driven to move downward by the upper mold seat 400, and the upper mold 500 will first enter the pre-pressing channel 640 to squeeze the tea leaves in the pre-pressing channel 640 toward the lower mold 200, and the upper mold 500 will move further downward until the upper mold 500 and the lower mold 200 are closed. At this time, all the tea leaves in the pre-pressing channel 640 are squeezed into the mold cavity formed by the lower mold 200 and the upper mold 500, and the upper mold 500 is kept under pressure for a set time to form the tea leaves in the mold cavity to form the pressed tea 10. After the pressed tea 10 is formed, the upper mold 500 moves upward, and the guide block 610, the first push block 620 and the second push block 630 are all moved and reset, and the pressed tea 10 in the lower mold cavity 210 can be taken out. In the embodiment of the present application, by setting the pre-pressing channel 640, it is possible to prevent the tea leaves from being scattered onto the lower mold seat 100 during the pressing process, reduce the cleaning work of the workers, and save tea leaves.

[0049] Please refer to Figure 1 , Figure 2 , Figure 7 and Figure 8 In some embodiments, a limiting groove 612 is provided on one side of the guide block 610 close to the lower die 200, and the lower die 200 is provided with a limiting edge 220 corresponding to the limiting groove 612. In the embodiment of the present application, when the guide block 610 is pushed to approach the lower die cavity 210, the limiting groove 612 cooperates with the limiting edge 220 to ensure that the lower opening of the guide channel 611 is exactly opposite to the opening of the lower die cavity 210, so that the tea leaves in the pre-pressing channel 640 can smoothly enter the lower die cavity 210, and the bottom wall of the pre-pressing channel 640 is prevented from blocking the movement of the tea leaves.

[0050] In some embodiments, the guide module 600 further includes a switch valve (not shown in the figure), which is arranged in the material guide channel 611, and is located on the side of the lower opening close to the first push block 620. The switch valve can be opened or closed to connect or block the material guide channel 611. It can be understood that the initial state of the switch valve is a closed state, that is, in the process of adding tea leaves into the material guide channel 611, the switch valve is closed, so that the material guide channel 611 is blocked. It can also be understood that when adding tea leaves into the material guide channel 611, the tea leaves should be added into the material guide channel 611 between the switch valve and the first push block 620, so that the tea leaves can be prevented from falling from the opening of the material guide channel 611 close to the second push block 630, and the tea leaves can also be prevented from falling from the lower opening of the material guide channel 611. When the second push block 630 runs to block the material guide channel 611, the switch valve can be opened to connect the material guide channel 611 as a whole. It can be understood by those skilled in the art that the switch valve is a prior art. For example, a blocking plate that is slidably connected to the material guide channel 611 can be set. As for the specific setting method of the switch valve, the embodiment of the present application does not make specific restrictions. Those skilled in the art can make a choice based on actual conditions, and will not go into details here.

[0051] Please refer to Figure 2 , Figure 3 , Figure 7 and Fig. 9 In some embodiments, the opening of the lower mold cavity 210 has the same shape as the cross section of the pre-pressing channel 640 along the second direction. It is understandable that the shape of the lower opening of the material guide channel 611 is also the same as the opening of the lower mold cavity 210. Specifically, if the shape of the opening of the lower mold cavity 210 is circular, the lower opening and the cross section of the pre-pressing channel 640 along the second direction are both circular; if the opening of the lower mold cavity 210 is square, the lower opening and the cross section of the pre-pressing channel 640 along the second direction are also square. This arrangement can ensure that the tea leaves in the pre-pressing channel 640 can smoothly enter the lower mold cavity 210.

[0052] It can be understood by those skilled in the art that the pressed tea 10 in the embodiment of the present application can have a variety of forms, such as dragon ball tea, square small cake tea, round small cake tea, leaf shape, copper coin shape, ingot shape, heart shape and other forms of pressed tea 10. For pressed tea 10 of different forms, those skilled in the art can adjust the shape of the space formed when the upper mold 500 and the lower mold 200 are closed to achieve it. For example, the upper mold 500 and the lower mold 200 are closed to form a spherical space, a square space or a cylindrical space, etc., and correspondingly, dragon ball tea, square small cake tea and round small cake tea can be pressed out. However, in the embodiment of the present application, the pressed tea 10 can be roughly divided into two categories, one is spherical, such as dragon ball tea, and this type of pressed tea 10 does not have edges and corners; the other is cake-shaped, such as square small cake tea, round small cake tea, etc., and this type of pressed tea 10 will have edges and corners. The following will be specifically introduced with the two categories of examples, but the embodiment of the present application does not limit the specific shape of the space formed after the upper mold and the lower mold are closed.

[0053] For ball-shaped dragon ball tea, please refer to Figure 5 and Figure 6 In some embodiments, the lower mold cavity 210 is a spherical groove, and the end of the upper mold 500 close to the lower mold 200 is provided with a spherical groove, and the lower mold 200 and the upper mold 500 are closed to form a spherical space; the lower mold cavity 210 is a spherical groove larger than a hemisphere, and the end of the upper mold 500 close to the lower mold 200 is a spherical groove smaller than a hemisphere. It can be understood by those skilled in the art that the shape of the lower mold cavity 210 is related to the shape of the finished pressed tea 10. For example, in the embodiment of the present application, it is necessary to prepare spherical pressed tea 10, then the lower mold cavity 210 can be set as a spherical groove, and the upper mold 500 is also provided with a spherical groove, so that when the upper mold 500 and the lower mold 200 are closed to form a spherical space, the tea leaves will be pressed into a spherical shape in the spherical space.

[0054] Please continue to refer to Figure 5 and Figure 6 Furthermore, in the embodiment of the present application, the lower mold cavity 210 is a spherical space larger than a hemisphere. Those skilled in the art can understand that the space of the lower mold cavity 210 only needs to be slightly larger than the hemisphere. In this way, after molding, the upper mold 500 moves up. Since the lower mold cavity 210 is larger than the hemisphere, during the demolding process, the formed pressed tea 10 is blocked at the opening of the lower mold cavity 210. Therefore, the pressed tea 10 will not be brought out by the upper mold 500 due to the adhesion between the pressed tea 10 and the upper mold 500, thereby facilitating the demolding of the upper mold 500 without adding additional auxiliary demolding tools for the demolding of the upper mold 500.

[0055] For pressed tea with angular cakes, please refer to Fig.11 and Fig.12, the lower mold cavity 210 is square or circular; the upper mold 500 is provided with a square boss or a circular boss at one end facing the lower mold 200, and the upper mold 500 and the lower mold 500 are closed to form a rectangular space or a cylindrical space; the upper mold 500 and the lower mold 200 are closed, and the tea leaves in the pre-pressing channel 640 can be pressed into square tea cakes or round tea cakes. Specifically in the embodiment of the present application, square tea cakes will be used as an example for explanation. When the pressed tea 10 to be pressed is a square pressed tea 10, the lower mold cavity 210 can be set to be square. Of course, it can be understood by those skilled in the art that when the pressed tea 10 is a triangle, the lower mold cavity 210 can be designed to be a triangle. In the embodiment of the present application, rounded corners are set at the four corners of the square of the lower mold cavity 210, which is more conducive to stress elimination and compression molding. Obviously, in the embodiment of the present application, since the square pressed tea 10 has corners, in the process of pushing the tea leaves from the material guide channel 611 into the pre-pressing channel 640, by controlling the movement sequence of the material guide block 610, the first push block 620 and the second push block 630, it is possible to effectively avoid the situation that the corners of the pressed tea 10 are not pressed properly, thereby ensuring the shape of the pressed tea 10 formed by the pressing. The movement sequence of the material guide block 610, the first push block 620 and the second push block 630 can be referred to the above description by those skilled in the art, and will not be repeated here. It is known to those skilled in the art that since the opening of the lower mold cavity 210 is substantially consistent with the internal size, after the molding is completed, during the demoulding process, the sticking caused by the extrusion between the upper mold 500 and the pressed tea 10 may cause the pressed tea 10 to stick to the upper mold 500 during the upward movement of the upper mold 500, causing the pressed tea 10 to move upward with the upper mold 500. Therefore, in this case, the upper mold 500 needs to be demoulded.

[0056] Please continue to refer to Fig.10 , Fig.11 and Fig.12Specifically, in some embodiments, the tea making mold further includes an ejector assembly 700 , and the ejector assembly 700 includes a mounting block 710 , a push rod 720 , an upper ejector pin 730 and a spring 740 . The upper mold 500 is provided with a stepped through hole along the second direction, and the stepped through hole includes a first hole and a second hole, the diameter of the first hole is smaller than the diameter of the second hole, and the first hole is close to one side of the lower mold 200; the mounting block 710 is fixedly connected to the upper end of one of the guide pillars 300, and the push rod 720 is fixedly connected to the lower part of the mounting block 710; and the upper mold 500 can move along the guide pillar 300 so that the push rod 720 is inserted into the second hole; the upper ejector pin 730 is slidably connected to the stepped through hole, and the upper ejector pin 730 includes a first section and a second section that are fixedly connected, the diameter of the first section is smaller than the diameter of the second section, the first section is at least partially located in the first hole, and the second section is located in the second hole, the spring 740 is sleeved on the first section, and the two ends of the spring 740 are respectively abutted against the second section and the step surface of the stepped through hole. Furthermore, the ejection assembly 700 further includes a cover, which covers the second hole, and the second section of the upper ejector pin 730 abuts against the cover, and a through hole is provided on the cover for the push rod 720 to pass through.

[0057] It can be understood that, in a natural state, the lower end of the first section of the push rod 720 can be flush with the lower end of the upper mold 500. In the embodiment of the present application, when the upper mold 500 moves up to the highest point, the upper ejector pin 730 can push the second section of the push rod 720, so that the second section of the push rod 720 drives the first section of the push rod 720 to move down, and the first section of the push rod 720 can move down to below the bottom of the upper mold 500, so that the pressed tea 10 stuck on the upper mold 500 can be ejected, thereby achieving demoulding. In the process of the push rod 720 moving down, the spring 740 is compressed. Therefore, when the upper mold 500 moves down and the push rod 720 is separated from the ejector pin, the spring 740 recovers its deformation, so that the upper ejector pin 730 enters the step hole opened in the upper mold 500, and the second section of the upper ejector pin 730 presses on the cover, so that during the molding process, the molding of the pressed tea 10 will not be affected, so that the shape of the pressed tea 10 is complete.

[0058] Please refer to Figure 6 and Fig.12In some embodiments, the tea-making mold further includes a lower ejector pin 800, which is slidably connected to the bottom of the lower mold 200, and when the lower ejector pin 800 slides along the second direction, one end of the lower ejector pin 800 can extend into the lower mold cavity 210. It can be understood by those skilled in the art that the tea-making mold further includes a driving device for driving the lower ejector pin 800 to move, which will not be described in detail here. In the embodiment of the present application, by setting the lower ejector pin 800, after the mold is opened, the lower ejector pin 800 can eject the pressed tea 10 stuck in the lower mold cavity 210, which is convenient for demoulding the lower mold 200, especially for the mold design in which the opening of the lower mold cavity 210 is smaller than the bottom of the lower mold cavity 210, the lower ejector pin 800 is indispensable. The driving method and setting method of the lower ejector pin 800 are both prior art, and will not be described in detail in the embodiment of the present application.

[0059] Please refer to Figure 1 and Figure 7 In some embodiments, the lower mold 200 is provided with a plurality of lower mold cavities 210, and the upper mold 500 and the guide mold group 600 are arranged in one-to-one correspondence with the lower mold cavities 210. By such an arrangement, a plurality of pressed teas 10 can be formed at one time, thereby increasing production efficiency. It can be understood by those skilled in the art that a plurality of lower ejector pins 800 also need to be arranged, and when a plurality of square lower mold cavities 210 are included, a plurality of upper ejector pins 730 also need to be arranged accordingly, but the guide column 300, the first drive device, etc. can be shared, so that efficiency can be improved and costs can be saved. For example, when the number of lower mold cavities 210 is two, the two upper molds 500 can be driven by the same drive device. It can be understood by those skilled in the art that the specific number of lower mold cavities 210 can be arranged according to the needs of those skilled in the art, and no specific restrictions are made here.

[0060] In other embodiments, the lower mold 200 can be movably arranged on the lower mold base 100. When the tea leaves are pressed into the lower mold 200 to form the pressed tea 10, after the guide mold 600 and the upper mold 500 are reset, the lower mold 200 can slide to other stations to demould the pressed tea 20, and at the same time, a new lower mold 200 slides to cooperate with the lower mold base 100 to press the next pressed tea 10. In this way, the production efficiency can be further improved.

[0061] refer to Fig.13 The present application also provides an embodiment of a tea pressing method, which adopts any of the above-mentioned tea making molds, and the tea pressing method comprises the following steps:

[0062] S1: After tea leaves are present in the material guiding channel 611 , the material guiding block 610 is moved to the lower opening to communicate with the lower mold cavity 210 .

[0063] In the embodiment of the present application, since the opening of the material guide channel 611 is relatively large and the material guide channel 611 is far away from the upper mold 500 and the lower mold 200, when tea leaves are added to the material guide channel 611, the upper mold 500 and the lower mold 200 will not interfere with each other, thereby facilitating the addition of tea leaves. It will be appreciated by those skilled in the art that in the embodiment of the present application, an automatic feeding device may also be provided, so that it is convenient to add tea leaves to the material guide channel 611 in a quantitative manner, and it is also possible to ensure that the consistency of the pressed tea 10 is increased. It will be appreciated by those skilled in the art that the device for automatically adding tea leaves may adopt a technology known in the art, which will not be described in detail herein.

[0064] S2: Move the first push block 620 and the second push block 630 to position the tea leaves in the pre-pressing channel 640. Specifically, the first push block 620 may be moved first, and then the second push block 630 may be moved, or the second push block 630 may be moved first, and then the first push block 620 may be moved.

[0065] In the embodiment of the present application, by pushing the tea leaves into the pre-pressing channel 640, during the pressing process of the tea leaves, due to the limitation of the pre-pressing channel 640, the tea leaves will not be scattered randomly, thus ensuring the consistency of the pressed tea produced and saving tea leaves. However, in actual use, when the shape of the pressed tea has edges and corners, the order of moving the first push block 620 and the second push block 630 is different. Although the pre-pressing channel 640 is finally formed, the edges and corners of the pressed tea will be different. In order to ensure the integrity of the edges and corners of the pressed tea, the present application also provides some embodiments. In this embodiment, step S2 may specifically include:

[0066] S21: Move the second push block 630 so that the second push block 630 blocks the opening of the material guide channel 611 away from the first push block 620 toward the side of the first push block 620. That is, first move the second push block 630 so that the second push block 630 blocks the opening of the material guide channel 611 away from the first push block 620. At this time, the second push block 630 has not reached the set position, that is, there is still a gap between the second push block 630 and the lower mold cavity 210 along the first direction.

[0067] S22: Move the first push block 620 so that the side of the first push block 620 facing the second push block 630 is aligned with the opening of the lower mold cavity 210. In this process, the tea leaves will be pushed toward the second push block 630, and some of the tea leaves will be temporarily stored in the interval between the lower mold cavity 210 and the second push block 630.

[0068] S23: Move the second push block 630 so that the side of the second push block 630 facing the first push block 620 is aligned with the opening of the lower mold cavity 210, and forms the pre-pressing channel 640 with the first push block 620, so that the tea leaves are located in the pre-pressing channel 640. In this process, the second push block 630 pushes the tea leaves located in the interval space toward the first push block 620, and the second push block 630 finally forms the pre-pressing channel 640 with the first push block 620, and finally all the tea leaves are located in the pre-pressing channel 640.

[0069] In the embodiment of the present application, through the specific pre-pressing channel 640 formation process, it can be ensured that the edges and corners of the pressed tea with edges and corners remain intact without being missing or loose during the final pressing and forming process.

[0070] S3: Move the upper mold 500 downward so that the upper mold 500 passes through the pre-pressing channel 640 and closes with the lower mold 200, so that the upper mold 500 and the lower mold 200 cooperate to press the tea leaves in the pre-pressing channel 640, so that the tea leaves are pressed to form pressed tea. In the embodiment of the present application, since the tea leaves are all located in the pre-pressing channel 640, that is, the tea leaves are constrained by the first push block 620 and the second push block 630, the tea leaves will not fall randomly during the downward movement of the upper mold 500, thereby ensuring that the tea leaves added to the material guide channel 611 can all be pressed into pressed tea. In this way, the consistency of the pressed tea can be ensured, and the mold blockage caused by the scattered tea leaves can be avoided.

[0071] S4: The upper mold 500 is kept stationary and maintained under pressure for a set time. After the upper mold 500, the first push block 620 and the second push block 630 are reset, the lower ejector pin 800 is moved to eject the pressed tea in the lower mold cavity 210. It can be understood by those skilled in the art that the pressure maintenance is to make the pressed tea better shaped. The specific pressure maintenance time is related to the pressure of the pressure maintenance and the properties of the tea leaves. Specifically, those skilled in the art can set it according to needs, and the embodiments of this application will not be repeated.

[0072] In the embodiment of the present application, the upper mold 500, the first push block 620 and the second push block 630 can be reset at the same time or in a certain order, which is not specifically limited here. In the embodiment of the present application, a lower ejector pin 800 is also provided to eject the pressed tea from the lower mold cavity 210, thereby facilitating demoulding.

[0073] Since the present process adopts any one of the above-mentioned tea-making moulds, the present process at least has the technical effects described by the above-mentioned tea-making moulds.

[0074] The present application also provides an embodiment of pressed tea, wherein the pressed tea in the embodiment is pressed by any of the above-mentioned tea-making molds, or is made by the above-mentioned tea pressing method. Since the pressed tea 10 is made by the above-mentioned tea-making mold, or is made by the above-mentioned tea pressing method, the pressed tea 10 at least includes the above-mentioned technical effects.

[0075] The embodiments of the present application are introduced in detail above. Specific examples are used in this article to illustrate the principles and implementation methods of the present application. The description of the above embodiments is only used to help understand the method of the present application and its central idea.
