DETAILED DESCRIPTION

[0033] The technical solutions in the embodiments of the present application will be described clearly and completely below in conjunction with the drawings in the embodiments of the present application.

[0034] 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.

[0035] refer to Figure 1 and Figure 7 The two guide pillars 300 are fixed to the lower die base 100 in parallel and spaced apart relation, and the lower die 200 is disposed on the lower die base 100 and located between the two guide pillars 300. Those skilled in the art will appreciate that the lower die 200 can be fixed to the lower die base 100 or movably disposed therein.

[0036] 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. 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. This is a well-known technology in the art and will not be described 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.

[0037] Please continue to refer to Figure 1 and Figure 7 Furthermore, the tea-making mold further includes a first drive device and a cam bearing follower 910. The fixed end of the first drive device is fixed to the mold frame (not shown in the figure), and the driving end of the first drive 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 facing away from the upper mold 500. Driven by the first drive 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.

[0038] Please continue to refer to Figure 1 and Figure 7 Furthermore, 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 extending along a 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. Both the upper opening and the lower opening are connected to the material guide channel 611. It will 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 the 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. In this way, tea leaves can easily enter the lower mold cavity 210 from the lower opening and can prevent tea leaves from falling onto the surface of the lower mold 200.

[0039] Please continue to refer to Figure 1 and Figure 7The guide block 610 is slidably connected to the lower die base 100. Specifically, a first guide plate (not shown) can be provided on the lower die base 100, and the bottom of the guide block 610 can be slidably provided on the first guide plate 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 repeated in the embodiment of the present application.

[0040] Please refer to Figure 2 、 Figure 3 、 Figure 8 and Figure 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 mold base 100; the first push block 620 and the second push block 630 are respectively located on both sides of the lower mold cavity 210. The material guide block 610 can move along the lower mold base 100 so that the lower opening is connected to the lower mold 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, and the second push block 630 can move toward the first push block 620 into the material guide channel 611 and enclose a pre-pressing channel 640 with the first push block 620. Along the direction from the upper mold base 400 to the lower mold base 100, the upper opening, the pre-pressing channel 640, the lower opening and the lower mold cavity 210 are connected in sequence; the first direction is the length direction of the material guide block 610, such as Figure 1 The X direction is shown in , 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, as shown in Figure 1 Y direction shown in .

[0041] Please continue to refer to Figure 1 、 Figure 2 、 Figure 3 、 Figure 7 、 Figure 8 and Figure 9Specifically, the lower mold 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 drive device for providing power for the movement of the second push block 630. It will 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 drive device. It will be understood by those skilled in the art that the initial position of the material guide block 610 is far away from the lower mold cavity 210, that is, the initial position of the material guide block 610 does not overlap with the lower mold cavity 210 in the second direction, and the initial position of the first push block 620 is located at the end of the material guide channel 611 away from the second push block 630.

[0042] Please refer to Figure 4 and Figure 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.

[0043] Please refer to Figure 1 and Figure 7 In the embodiment of the present application, when the tea leaves need to be pressed, the tea leaves are first added to the guide channel 611 from the upper opening of the guide channel 611. Since the guide block 610 is away from the upper mold 500 at this time, when adding tea leaves to the guide channel 611 of the guide block 610, it will not be interfered by the upper mold 500, and since the upper opening of the guide channel 611 can be designed to be larger, it can be further facilitated to add tea leaves to the guide channel 611. In the embodiment of the present application, since the initial position of the guide block 610 is away from the lower mold cavity 210, and the upper opening of the guide channel 611 can be designed as needed, the embodiment of the present application can also be provided with an automatic feeding device for use in conjunction with the guide channel 611, thereby further increasing the convenience of tea leaves. 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 described in detail. It can be understood by those skilled in the art that after the tea leaves are put into the guide channel 611, the tea leaves are located on the side of the first push block 620 close to the second push block 630.

[0044] Please refer to Figure 2 and Figure 8After the tea leaves are added, the material guide block 610 is first moved, and the lower opening of the material guide channel 611 is connected to the lower mold cavity 210. At this time, the second push block 630 is moved so that the second push block 630 blocks the opening of the material guide channel 611 away from the side of the first push block 620. It can be understood by those skilled in the art that at this time, there is still a gap between the second push block 630 and the lower mold cavity 210. Then push the first push block 620 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 push the second push block 630 again to push the tea leaves toward the first push block 620, and make the second push block 630 and the first push block 620 enclose to form a pre-pressing channel 640. At this time, the tea leaves are confined in the pre-pressing channel 640. Figure 3 and Figure 9 shown.

[0045] It will 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 is possible to ensure that the corners of the pressed tea leaves 10 with corners are pressed tightly during the pressing process, and to avoid loose corners or missing corners of the pressed tea leaves 10 with corners. Of course, for pressed tea leaves 10 without corners, the order of pushing the tea leaves can be adjusted. For example, for spherical tea leaves, the second push block 630 can be pushed first 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. No specific limitation is imposed.

[0046] Please refer to Figure 4 and Figure 10In the embodiment of the present application, after the tea leaves are concentrated in the pre-pressing channel 640, the upper mold 500 is driven downward by the upper mold base 400. The upper mold 500 will first enter the pre-pressing channel 640 and squeeze the tea leaves in the pre-pressing channel 640 toward the lower mold 200. 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. The upper mold 500 maintains pressure for a set time to form the tea leaves in the mold cavity to form 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 providing the pre-pressing channel 640, it is possible to prevent tea leaves from spilling onto the lower mold base 100 during the pressing process, reduce the cleaning work of workers, and save tea leaves.

[0047] Please refer to Figure 1 、 Figure 2 、 Figure 7 and Figure 8 In some embodiments, a limiting groove 612 is provided on a side of the guide block 610 close to the lower mold 200, and the lower mold 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 toward the lower mold 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 the opening of the lower mold cavity 210. In this way, the tea leaves in the pre-pressing channel 640 can be smoothly transferred into the lower mold cavity 210, and the bottom wall of the pre-pressing channel 640 can be prevented from blocking the flow of the tea leaves.

[0048] In some embodiments, the guide module 600 further includes an on-off valve (not shown). The on-off valve is disposed within the material guide channel 611, located on the side of the lower opening near the first push block 620. The on-off valve can be opened or closed to connect or block the material guide channel 611. It is understood that the on-off valve is initially closed. That is, during the process of adding tea leaves to the material guide channel 611, the on-off valve is closed, thereby blocking the material guide channel 611. It is also understood that tea leaves added to the material guide channel 611 should be added to the material guide channel 611 between the on-off valve and the first push block 620. This prevents tea leaves from falling out of the opening of the material guide channel 611 near the second push block 630, as well as from the lower opening of the material guide channel 611. Once the second push block 630 has blocked the material guide channel 611, the on-off valve can be opened, connecting the entire material guide channel 611. It can be understood by those skilled in the art that the switch valve is a prior art. For example, a blocking plate can be provided to slide and connect the material guide channel 611. As for the specific setting method of the switch valve, the embodiment of the present application does not impose any specific restrictions. Those skilled in the art can make a choice based on the actual situation, and will not go into details here.

[0049] Please refer to Figure 2 、 Figure 3 、 Figure 7 and Figure 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 perpendicular to the second direction. It can be understood that the shape of the lower opening of the material guide channel 611 is also the same as the shape of the opening of the lower mold cavity 210. Specifically, if the shape of the opening of the lower mold cavity 210 is circular, then the cross-section of the lower opening and the pre-pressing channel 640 along the second direction perpendicular to the second direction are both circular; if the opening of the lower mold cavity 210 is square, then the cross-section of the lower opening and the pre-pressing channel 640 along the second direction perpendicular to 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.

[0050] Those skilled in the art will appreciate that the pressed tea 10 in the embodiments of the present application can have a variety of shapes, including, for example, dragon ball tea, square tea cakes, round tea cakes, leaf-shaped tea, copper coin-shaped tea, ingot-shaped tea, heart-shaped tea, and other various shapes. To achieve different shapes of pressed tea 10, 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. For example, the upper mold 500 and the lower mold 200 can be closed to form a spherical space, a square space, or a cylindrical space, and accordingly, dragon ball tea, square tea cakes, and round tea cakes can be pressed. However, in the embodiments of the present application, the pressed tea 10 can be generally divided into two categories: one is spherical, such as dragon ball tea, which has no edges or corners; the other is cake-shaped, such as square tea cakes and round tea cakes, which have edges or corners. The following will provide a detailed description of the embodiments based on these two categories, but the embodiments of the present application are not limited to the specific shape of the space formed when the upper and lower molds are closed.

[0051] 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, the upper mold 500 is provided with a spherical groove at one end close to the lower mold 200, 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 upper mold 500 is provided with a spherical groove smaller than a hemisphere at one end close to the lower mold 200. It will 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, if it is necessary to prepare spherical pressed tea 10, the lower mold cavity 210 can be set as a spherical groove, and the upper mold 500 is also provided with a spherical groove. In this way, 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.

[0052] 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 will 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 upward. 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 of the upper mold 500 due to 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 demolding the upper mold 500.

[0053] For pressed tea cakes with edges and corners, please refer to Figure 11 and Figure 12, the lower die cavity 210 is square or circular; the upper die 500 is provided with a square boss or a circular boss at one end facing the lower die 200, and the upper die 500 and the lower die 500 are closed to form a rectangular space or a cylindrical space; the upper die 500 and the lower die 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 die cavity 210 can be set to be square. Of course, those skilled in the art will understand that when the pressed tea 10 is triangular, the lower die cavity 210 can be designed to be triangular. In the embodiment of the present application, rounded corners are set at the four square corners of the lower die 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, by controlling the movement sequence of the guide block 610, the first push block 620, and the second push block 630 during the process of pushing the tea leaves from the material guide channel 611 into the pre-pressing channel 640, it is possible to effectively avoid the corners of the formed pressed tea 10 from being molded incorrectly, thereby ensuring the shape of the molded pressed tea 10. Regarding the movement sequence of the guide block 610, the first push block 620, and the second push block 630, those skilled in the art can refer to the above description and will not be repeated here. It is understood by those skilled in the art that since the opening and internal dimensions of the lower mold cavity 210 are substantially consistent, after the molding is completed, during the demolding process, the upper mold 500 and the pressed tea 10 may stick to each other 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 demolded.

[0054] Please continue to refer to Figure 10 、 Figure 11 and Figure 12Specifically, in some embodiments, the tea-making mold further includes an ejection assembly 700 , and the ejection 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 respectively abut against the step surfaces of the second section and 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 formed on the cover for the push rod 720 to pass through.

[0055] It is understood that, in its 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. Furthermore, in the embodiment of the present application, when the upper mold 500 moves upward to its highest point, the upper ejector pin 730 can push the second section of the push rod 720, causing the second section of the push rod 720 to move downward, and the first section of the push rod 720 can move downward below the bottom of the upper mold 500. This can eject the pressed tea 10 adhered to the upper mold 500, thereby achieving demolding. During the downward movement of the push rod 720, the spring 740 is compressed. Therefore, when the upper mold 500 moves downward and the push rod 720 is separated from the ejector pin, the spring 740 recovers its deformation, allowing the upper ejector pin 730 to enter the stepped hole defined in the upper mold 500, and the second section of the upper ejector pin 730 to press against the cover. This prevents the pressed tea 10 from being affected during the molding process, ensuring that the pressed tea 10 has a complete shape.

[0056] Please refer to Figure 6 and Figure 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 will 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.

[0057] 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 module 600 are arranged in a 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 will be understood by those skilled in the art that a plurality of lower ejector pins 800 also need to be provided, and when a plurality of square lower mold cavities 210 are included, a plurality of upper ejector pins 730 also need to be provided 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 will be understood by those skilled in the art that the specific number of lower mold cavities 210 can be set as needed by those skilled in the art, and no specific restrictions are made here.

[0058] In other embodiments, the lower mold 200 can be movably mounted on the lower mold base 100. When the tea leaves are pressed into the lower mold 200 to form the pressed tea 10, the guide mold 600 and the upper mold 500 are reset. The lower mold 200 can then slide to another station to demold the pressed tea 20. Simultaneously, a new lower mold 200 slides to engage with the lower mold base 100 to press the next batch of pressed tea 10. This can further improve production efficiency.

[0059] refer to Figure 13 The present application also provides an embodiment of a tea pressing method, which uses any of the above-mentioned tea making molds, and the tea pressing method comprises the following steps:

[0060] S1: After tea leaves are present in the material guiding channel 611 , the material guiding block 610 is moved to the lower opening to connect with the lower mold cavity 210 .

[0061] 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 tea leaves can be added to the material guide channel 611 in a quantitative manner and the consistency of the pressed tea 10 can be increased. It will be appreciated by those skilled in the art that the device for automatically adding tea leaves may adopt a technology well known in the art and will not be described in detail herein.

[0062] S2: Move the first push block 620 and the second push block 630 so that the tea leaves are located in the pre-pressing channel 640. Specifically, the first push block 620 may be moved first, and then the second push block 630, or the second push block 630 may be moved first, and then the first push block 620.

[0063] 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 randomly scattered, 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:

[0064] S21: The second push block 630 is moved so that the second push block 630 is directed toward the side of the first push block 620 to block the opening of the material guiding channel 611 away from the first push block 620. That is, the second push block 630 is first moved so that the second push block 630 blocks the opening of the material guiding channel 611 away from the first push block 620. At this time, the second push block 630 has not yet 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.

[0065] S22: The first push block 620 is moved 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. During this process, the tea leaves are pushed toward the second push block 630, and some of the tea leaves are temporarily stored in the space between the lower mold cavity 210 and the second push block 630.

[0066] S23: The second push block 630 is moved 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 the second push block 630 and the first push block 620 form the pre-pressing channel 640, 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 in the space toward the first push block 620, and the second push block 630 and the first push block 620 eventually form the pre-pressing channel 640, so that all the tea leaves are finally located in the pre-pressing channel 640.

[0067] 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 and will not be missing or loose during the final pressing and molding process.

[0068] 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 guaranteed, and the mold blockage caused by the scattered tea leaves can be avoided.

[0069] S4: The upper mold 500 is held stationary 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 from the lower mold cavity 210. Those skilled in the art will appreciate that holding pressure is intended to ensure better shaping of the pressed tea. The specific holding time depends on the holding pressure and the properties of the tea leaves. Those skilled in the art can adjust the time as needed, and this embodiment will not be further detailed.

[0070] 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 simultaneously 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.

[0071] Since this process adopts any of the above-mentioned tea-making molds, this process at least has the technical effects described in the above-mentioned tea-making molds.

[0072] The present application also provides an embodiment of a pressed tea. The pressed tea in this embodiment is pressed using any of the above-described tea-making molds, or is made using the above-described tea pressing method. Because the pressed tea 10 is made using the above-described tea-making mold or using the above-described tea pressing method, the pressed tea 10 at least provides the above-described technical effects.

[0073] The above is a detailed introduction to the embodiments of the present application. Specific examples are used herein 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.
