[0002] In the tea processing industry, pressing tea leaves into cakes is a common forming method.

This method often involves manual labor or semi-automatic equipment, with steaming and pressing processes usually performed separately. Manual handling of the tea leaves is cumbersome, labor-intensive, and results in low production efficiency. Furthermore, the steamed tea leaves tend to cool down during handling and pressing, causing them to harden and affecting the subsequent pressing effect and the compactness of the tea cake.

[0016] This application provides an automatic tea pressing and forming device. Initially, the first and second limiting cylinders are located at the top of the steaming section and the pressing section, respectively. The steam mechanism is activated, and the tea to be pressed is placed on the steaming section via the first limiting cylinder, which acts as a limit. After the tea is steamed, a rotating mechanism is activated, causing the first and second limiting cylinders to move in a circular motion along an annular groove. This moves the first limiting cylinder, carrying the steamed tea, above the pressing section, while the second limiting cylinder moves above the steaming section, thus exchanging positions. At this time, the pressing mechanism presses the steamed tea in the first limiting cylinder into shape. Simultaneously, the tea to be steamed is poured into the second limiting cylinder, located above the steaming section, for steaming. Then, the pressing mechanism presses the tea in the first limiting cylinder... The tea cake is formed into a tea cake. Next, the ejector mechanism pushes the formed tea cake from below the pressing section to the top of the first limiting cylinder. Then, a pushing mechanism pushes the tea cake out from the top of the first limiting cylinder. At this time, the tea in the second limiting cylinder has also completed steaming, thus completing the first round of tea cake pressing. Then, the rotating mechanism rotates again, exchanging the positions of the second and first limiting cylinders. The second limiting cylinder, carrying the steamed tea, moves to the top of the pressing section, where more tea is added to the first limiting cylinder for steaming. Meanwhile, the pressing mechanism presses the steamed tea in the second limiting cylinder into a tea cake, which is then ejected by the ejector mechanism and pushed out by the pushing mechanism. At this time, the tea in the first limiting cylinder has also completed steaming. Through this method, the steaming and pressing operations are simultaneously automated. The steaming process softens the tea before pressing, allowing for better pressing into tea cakes.

[0017] The automatic tea pressing and forming equipment of this application has the following technical advantages compared with the prior art: (1) By driving the two limiting cylinders to slide synchronously and exchange positions in the annular groove of the base through the rotating mechanism, the steaming and pressing processes can be carried out at the same time. Steaming and pressing do not need to wait, which greatly improves production efficiency and realizes continuous automated operation.

[0018] (2) The ejection mechanism, in conjunction with the pushing mechanism, can automatically eject the tea cake from the tea pressing cylinder to the top of the limiting cylinder and push it out laterally after pressing and molding, thus realizing automatic demolding and material discharge without manual intervention, which significantly reduces labor intensity.

[0019] (3) By configuring a timed and quantitative feeding mechanism, the amount of tea leaves put into the steaming section each time can be precisely controlled, thereby ensuring the consistency of the weight of each batch of tea cakes and improving the standardization level and quality stability of the product.

[0020] (4) The equipment has a compact structure, and the actions of steaming, workstation interchange, pressing, ejection and pushing are coordinated. It is easy to operate and can stably realize the automated production of feeding, steaming, pressing and discharging.

[0025] To better understand the above-mentioned objectives, features, and advantages of this application, the application will be further described in detail below with reference to the accompanying drawings and specific embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0026] Many specific details are set forth in the following description in order to provide a full understanding of this application. However, this application may also be implemented in other ways different from those described herein. Therefore, the scope of protection of this application is not limited to the specific embodiments disclosed below.

[0027] The following reference Figures 1 to 6 This application describes an automatic tea pressing and forming device and a tea making machine provided according to some embodiments.

[0028] Example 1 An automatic tea pressing and forming device includes a base 1, a rotating mechanism 2, a mounting frame 3, a steaming mechanism 4, a tea pressing mechanism 5, an ejection mechanism 6, and a pushing mechanism 7. The base 1 has an annular groove 11 at its bottom. A steaming section 12 and a pressing section 13 are respectively embedded in the radially opposite sides of the bottom of the annular groove 11. A first limiting cylinder 14 and a second limiting cylinder 15 are respectively provided on the top of the steaming section 12 and the pressing section 13. Both the first limiting cylinder 14 and the second limiting cylinder 15 are slidably connected to the sidewall of the annular groove 11. The rotating mechanism 2 is mounted on the base 1. At the center of the annular groove 11; the rotating mechanism 2 is used to drive the first limiting cylinder 14 and the second limiting cylinder 15 to slide simultaneously in the annular groove 11; the mounting bracket 3 is fixedly set on the top of the base 1; the steaming mechanism 4 is set on the bottom of the base 1; the steaming mechanism 4 is connected to the tea steaming part 12; the tea pressing mechanism 5 is set on the mounting bracket 3; the tea pressing mechanism 5 is located above the tea pressing part 13; the ejection mechanism 6 is set on the bottom of the base 1 at the position corresponding to the tea pressing part 13; the pushing mechanism 7 is set on the mounting bracket 3; the pushing mechanism 7 is located on the side above the second limiting cylinder 15 near the rotating mechanism 2.

[0029] Specifically, the first limiting cylinder 14 and the second limiting cylinder 15 have the same structure and size. The annular groove 11 has sliding grooves on both sides, and the first limiting cylinder 14 and the second limiting cylinder 15 have sliders that are adapted to the sliding grooves on both sides.

[0030] According to an automatic tea pressing and forming device of this embodiment, in the initial position, the first limiting cylinder 14 and the second limiting cylinder 15 are respectively located at the top of the tea steaming section 12 and the tea pressing section 13. The steam mechanism 4 is activated, and the tea to be pressed is placed on the tea steaming section 12 through the first limiting cylinder 14. The first limiting cylinder 14 acts as a limiting device for the tea to be steamed. After the tea is steamed, the rotating mechanism 2 is activated. The rotating mechanism drives the first limiting cylinder 14 and the second limiting cylinder 15 to move in a circular motion along the annular groove 11, so that the first limiting cylinder 14, carrying the steamed tea, moves to the top of the tea pressing section 13, while the second limiting cylinder 15 moves to the top of the tea steaming section 12, realizing the interchange of the positions of the first limiting cylinder 14 and the second limiting cylinder 15. At this time, the tea pressing mechanism 5 presses and forms the steamed tea in the first limiting cylinder 14. While the tea pressing mechanism 5 is working, the tea to be steamed is poured into the second limiting cylinder 15 located above the tea steaming section 12 for steaming. Then, the tea pressing mechanism 5 presses the first limiting cylinder 14... The tea leaves in cylinder 14 are pressed into tea cakes. Then, the ejector mechanism 6 pushes the formed tea cake from below the pressing section 13 to the top of the first limiting cylinder 14. The pushing mechanism 7 then pushes the tea cake out from the top of the first limiting cylinder 14. At this time, the tea leaves in the second limiting cylinder 15 have also completed steaming, thus completing the first round of tea cake pressing. Next, the rotating mechanism 2 rotates again, swapping the positions of the second limiting cylinder 15 and the first limiting cylinder 14. The second limiting cylinder 15 carries the steamed tea leaves to the pressing section... Above the tea section 13, tea leaves to be steamed are added to the first limiting cylinder 14 for steaming, while the tea pressing mechanism 5 presses the steamed tea leaves in the second limiting cylinder 15 into a tea cake, and then pushes the tea cake out through the ejection mechanism 6 and the pushing mechanism 7. At this time, the tea leaves in the first limiting cylinder 14 have also been steamed. Through the above method, the automatic operation of steaming and pressing tea is realized at the same time. The tea leaves are softened by steaming before pressing, which can better press the tea leaves into tea cakes.

[0031] Furthermore, as an optional implementation of this embodiment, the tea steaming section 12 includes a tea steaming through hole 121, a tea steaming plate 122, and a plurality of steam holes 123; wherein, the tea steaming through hole 121 is disposed through the bottom of the annular groove 11; the tea steaming through hole 121 is connected to the steam mechanism 4; the first limiting cylinder 14 is disposed at the top of the tea steaming through hole 121; the tea steaming plate 122 is disposed inside the tea steaming through hole 121; the top of the tea steaming plate 122 is flush with the bottom of the annular groove 11; and the plurality of steam holes 123 are evenly disposed through the tea steaming plate 122.

[0032] It should be noted that the tea leaves enter the steaming plate 122 through the first limiting cylinder 14 or the second limiting cylinder 15, and the steaming through hole 121 is provided through the bottom of the annular groove 11 and communicates with the steam mechanism 4. The steaming plate 122 is located in the steaming through hole 121. Therefore, when the steam mechanism 4 is turned on, steam enters the steaming through hole 121 and heats the steaming plate 122. At the same time, steam enters the tea leaves through the steam hole 123 on the steaming plate 122, thereby steaming the tea leaves. The top of the steaming plate 122 is flush with the bottom of the annular groove 11, so that the first limiting cylinder 14 or the second limiting cylinder 15 will not get stuck. The steamed tea leaves will move around the annular groove 11 to the top of the tea pressing part 13.

[0033] Further, as an optional embodiment of this invention, the tea pressing unit 13 includes a tea pressing through hole 131, a limiting ring 132, a tea pressing cylinder 133, a return spring 134, and a return plate 135; wherein, the tea pressing through hole 131 is disposed through the bottom of the annular groove 11 on the side away from the tea steaming unit 12; the tea pressing mechanism 5 and the ejection mechanism 6 are respectively located above and below the tea pressing through hole 131; the limiting ring 132 is disposed on the side wall of the tea pressing through hole 131 near the bottom of the base 1; the tea pressing cylinder 133... The tea pressing tube 133 is placed on the limiting ring 132 and is located inside the tea pressing hole 131. The top of the tea pressing tube 133 is lower than the bottom of the annular groove 11. The reset spring 134 is located inside the tea pressing tube 133. One end of the reset spring 134 is fixedly connected to the bottom wall of the tea pressing tube 133. The reset plate 135 is located inside the tea pressing tube 133. The reset plate 135 is fixedly connected to the end of the reset spring 134 away from the bottom wall of the tea pressing tube 133. The reset plate 135 is located inside the tea pressing tube 133 in its natural state.

[0034] Specifically, the outer diameter of the tea pressing cylinder 133 is larger than the inner diameter of the limiting ring 132, but smaller than the outer diameter of the limiting ring 132, and the diameter of the reset plate 135 is smaller than the inner diameter of the tea pressing cylinder 133.

[0035] It should be noted that when the steamed tea leaves move to the steaming section 13 along with the first limiting cylinder 14 or the second limiting cylinder 15, the tea leaves are located on the reset plate 135. First, the tea pressing mechanism 5 is activated to press the tea leaves on the reset plate 135. During the pressing process, the first limiting cylinder 14 or the second limiting cylinder 15 acts as a limiting and shaping element. When the tea leaves are subjected to the pressure of the tea pressing mechanism 5, they press down on the reset plate 135, which in turn causes the reset plate 135 to press against the reset spring 134. This causes the tea pressing cylinder 133 to be subjected to a downward force. Since the tea pressing cylinder 133 is placed on the limiting ring 132, and the outer diameter of the tea pressing cylinder 133 is larger than the inner diameter of the limiting ring 132, the tea pressing cylinder 133 is subjected to a downward force from the limiting ring 132. An upward force in the opposite direction is applied, at which point the return spring 134 is fully compressed, the return plate 135 applies an upward force to the tea leaves, and the tea pressing mechanism 5 applies a downward force to the tea leaves, thereby compressing the tea leaves to obtain a compressed tea cake. At this time, the tea pressing mechanism 5 stops working, the pressure on the return spring 134 disappears, the return spring 134 resets, and drives the return plate 135 to reset, thereby pushing the pressed tea cake upward. Then, the ejection mechanism 6 is controlled to push the tea pressing cylinder 133 upward from below the tea pressing through hole 131, so that the tea cake is fully exposed to the top of the first limiting cylinder 14 or the second limiting cylinder 15. Then, the pushing mechanism 7 is controlled to push the tea cake out from the top of the first limiting cylinder 14 or the second limiting cylinder 15.

[0036] Further, as an optional implementation of this embodiment, the rotating mechanism 2 includes a rotary motor 21, a bearing seat 22, a transmission shaft 23, and a rotating rod 24; wherein, the rotary motor 21 is fixedly disposed at the bottom of the base 1; the bearing seat 22 is fixedly disposed at the top of the base 1; the transmission shaft 23 is vertically disposed through the base 1; the transmission shaft 23 is rotatably connected to the base 1; the transmission shaft 23 is located at the center of the annular groove 11; one end of the transmission shaft 23 is fixedly connected to the output end of the rotary motor 21, and the other end is rotatably connected to the bearing seat 22; the rotating rod 24 is vertically disposed through the end of the transmission shaft 23 near the bearing seat 22; the two ends of the rotating rod 24 are equidistant from the transmission shaft 23; the two ends of the rotating rod 24 are fixedly connected to the first limiting cylinder 14 and the second limiting cylinder 15, respectively.

[0037] Specifically, the rotary motor 21 is a stepper motor with a control system.

[0038] It should be noted that when the rotary motor 21 rotates, it drives the transmission shaft 23 to rotate on the bearing seat 22. The rotation of the transmission shaft 23 drives the rotating rod 24 to rotate 180°. The two ends of the rotating rod 24 are fixedly connected to the first limiting cylinder 14 and the second limiting cylinder 15 respectively. Therefore, the rotation of the rotating rod 24 drives the first limiting cylinder 14 and the second limiting cylinder 15 to move in the annular groove 11, thereby realizing the interchange of the working positions of the first limiting cylinder 14 and the second limiting cylinder 15. Since the rotary motor 21 is a stepper motor, the forward rotation angle of the stepper motor is set to 180° to realize the interchange of the working positions of the first limiting cylinder 14 and the second limiting cylinder 15. The time interval between two forward rotations is set to set the interval time for the interchange of the working positions of the first limiting cylinder 14 and the second limiting cylinder 15. This time interval is the sum of the time for pressing, ejecting and pushing out the tea cake.

[0039] Furthermore, as an optional implementation of this embodiment, the steam mechanism 4 includes a steam generator 41, a steam cylinder 42, a steam pipe 43, and a steam nozzle 44; wherein, the steam generator 41 is disposed at the bottom of the base 1; the steam cylinder 42 is disposed at the bottom of the base 1; the steam cylinder 42 is located below the tea steaming passage 121; the steam cylinder 42 is connected to the tea steaming passage 121; one end of the steam pipe 43 is connected to the steam generator 41, and the other end passes through the side wall of the steam cylinder 42 to the inside of the steam cylinder 42; the steam nozzle 44 is disposed on the inner side wall of the steam cylinder 42; the steam nozzle 44 is connected to the end of the steam pipe 43 located inside the steam cylinder 42.

[0040] It should be noted that after the steam generator 41 is started, it generates steam; the steam enters the steam nozzle 44 located in the steam cylinder 42 from the steam pipe 43, and the steam is sprayed into the steam cylinder 42 through the steam nozzle 44. The steam moves upward to heat the tea steaming plate 122, and enters the tea leaves through the steam hole 123 on the tea steaming plate 122 to steam the tea leaves.

[0041] Furthermore, as an optional implementation of this embodiment, the tea pressing mechanism 5 includes a first electro-hydraulic rod 51, a connecting block 52, and a pressing head 53; wherein, the first electro-hydraulic rod 51 is vertically arranged on the mounting frame 3; the first electro-hydraulic rod 51 is located above the tea pressing through hole 131; the fixed end of the first electro-hydraulic rod 51 is fixedly connected to the mounting frame 3; the connecting block 52 is arranged at the telescopic end of the first electro-hydraulic rod 51; the pressing head 53 is arranged at the end of the connecting block 52 away from the first electro-hydraulic rod 51; the pressing head 53 is threadedly connected to the connecting block 52.

[0042] It should be noted that when the first electric hydraulic rod 51 is activated, its telescopic end extends and moves downward, causing the connecting block 52 to move downward. The pressure head 53 is located at the end of the connecting block 52 away from the first electric hydraulic rod 51. Therefore, the downward movement of the connecting block 52 causes the pressure head 53 to move downward. The pressure head 53 moves downward into the first limiting cylinder 14 or the second limiting cylinder 15 to press the tea leaves in the tea pressing cylinder 133 inside the tea pressing hole 131. After pressing is completed, the telescopic end of the first electric hydraulic rod 51 is controlled to retract.

[0043] Furthermore, as an optional implementation of this embodiment, the ejection mechanism 6 includes a first fixed plate 61 and an electric telescopic rod 62; wherein, the first fixed plate 61 is fixed to the bottom of the base 1 at intervals by bolts; the electric telescopic rod 62 is vertically arranged on the top of the first fixed plate 61; the electric telescopic rod 62 is located below the tea pressing hole 131.

[0044] It should be noted that the first fixing plate 61 is fixed to the bottom of the base 1 at intervals by bolts. The first fixing plate 61 is spaced apart from the bottom of the base 1. The electric telescopic rod 62 is vertically set at the top of the first fixing plate 61, that is, the electric telescopic rod 62 is located between the first fixing plate 61 and the bottom of the base 1. After the tea is pressed, the telescopic end of the electric telescopic rod 62 is controlled to push the tea pressing cylinder 133 from the bottom of the tea pressing hole 131 to the top of the tea pressing cylinder 133, thereby pushing the tea cake to the top of the first limiting cylinder 14 or the second limiting cylinder 15.

[0045] Furthermore, as an optional implementation of this embodiment, the pushing mechanism 7 includes a second fixed plate 71 and a second electro-hydraulic rod 72; wherein, one end of the second fixed plate 71 is fixedly connected to the mounting frame 3; the second fixed plate 71 is located above the second limiting cylinder 15 on the side near the rotating mechanism 2; the second electro-hydraulic rod 72 is laterally arranged at the end of the second fixed plate 71 away from the mounting frame 3; the fixed end of the second electro-hydraulic rod 72 is fixedly connected to the side of the second fixed plate 71 near the second limiting cylinder 15, and the telescopic end of the second electro-hydraulic rod 72 points towards the second limiting cylinder 15.

[0046] It should be noted that when the pressed tea cake is pushed to the top of the first limiting cylinder 14 or the second limiting cylinder 15, the second electric hydraulic rod 72 is activated. The telescopic end of the second electric hydraulic rod 72 extends and moves laterally toward the tea cake, pushing the tea cake off the top of the first limiting cylinder 14 or the second limiting cylinder 15.

[0047] Furthermore, as an optional implementation of this embodiment, the automatic tea pressing and forming equipment also includes a timed and quantitative feeding mechanism 8, a discharge conveying mechanism 9, and a support frame 10; wherein, the timed and quantitative feeding mechanism 8 is fixedly mounted on the mounting frame 3; the timed and quantitative feeding mechanism 8 is located above the tea steaming section 12; the timed and quantitative feeding mechanism 8 is used to feed tea leaves onto the tea steaming section 12 in a timed and quantitative manner; the discharge conveying mechanism 9 is located on one side of the base 1, and the discharge conveying mechanism 9 is located in the direction pointed to by the extension end of the second electric hydraulic rod 72; the discharge conveying mechanism 9 is used to convey the pressed and formed tea cake; the support frame 10 is fixedly mounted on the bottom of the base 1.

[0048] Specifically, the timed and quantitative feeding mechanism 8 includes a third fixed plate 81, an annular mounting frame 82, and a timed and quantitative feeding hopper 83; wherein, the third fixed plate 81 is fixedly connected to the mounting frame 3; the annular mounting frame 82 is fixedly connected to the third fixed plate 81, and the annular mounting frame 82 is located above the tea steaming plate 122 of the tea steaming section 12; the timed and quantitative feeding hopper 83 is installed in the annular mounting frame 82, and the timed and quantitative feeding hopper 83 is located above the tea steaming plate 122.

[0049] It should be noted that by setting the feeding amount and feeding interval of the timed and quantitative feeding hopper 83, the feeding amount can control the weight of the pressed tea cake, and the feeding interval is the sum of the time for pressing, ejecting and pushing out the tea cake, so as to realize the automatic cycle of feeding, steaming, pressing and discharging.

[0050] Specifically, the discharge conveying mechanism 9 includes a fixed frame 91 and a conveyor belt 92; wherein, the fixed frame 91 is fixedly installed on one side of the base 1, and the fixed frame 91 is located in the direction pointed to by the telescopic end of the second electric hydraulic rod 72; the discharge conveying mechanism 9 is used to convey the pressed tea cake. The conveyor belt 92 is installed on the fixed frame 91; the top position of the conveyor belt 91 is lower than the top position of the first limiting cylinder 14 and the second limiting cylinder 15.

[0051] It should be noted that when the second electric hydraulic rod pushes the tea cake at the top of the first limiting cylinder 14 or the second limiting cylinder 15 toward the conveyor belt 92, the tea cake will fall onto the conveyor belt 92 and move with the conveyor belt to the next processing station because the top position is lower than the top position of the first limiting cylinder 14 and the second limiting cylinder 15.

[0052] The working principle of an automatic tea pressing and forming device according to this embodiment is as follows: The steam generator 41 is started, followed by the timed and metered feeding hopper 83. The timed and metered feeding hopper 83 feeds the tea leaves into the first limiting cylinder 14 for the first time, causing the tea leaves to fall onto the steaming plate 122. Steam generated by the steam generator 41 enters the steam nozzle 44 located in the steam cylinder 42 through the steam pipe 43. The steam is then sprayed into the steam cylinder 42 through the steam nozzle 44. The steam rises and heats the steaming plate 122, entering the tea leaves through the steam holes 123 on the steaming plate 122 to steam the tea leaves. After steaming... Then, the rotary motor 21 is started, driving the rotating rod 24 to rotate 180°, so that the first limiting cylinder 14 and the second limiting cylinder can move in a circle along the annular slide groove 11 to realize the exchange of work positions. Then, the steamed tea leaves move to the tea pressing part 13 with the first limiting cylinder 14. Then, the timed and quantitative feeding hopper 83 feeds the second batch of tea leaves into the second limiting cylinder 15. The tea leaves in the second limiting cylinder 15 are steamed. At the same time, the first electric hydraulic rod 51 is started. The telescopic end of the first electric hydraulic rod 51 extends and moves downward to press the tea through hole. The tea leaves in the inner tea cylinder 133 are pressed; after pressing, the telescopic end of the first electric hydraulic rod 51 is retracted; then the telescopic end of the electric telescopic rod 62 is activated, pushing the tea cylinder 133 from below the tea pressing hole 131 upwards, thereby pushing the tea cake to the top of the first limiting cylinder 14; then the telescopic end of the second electric hydraulic rod 72 is activated, extending and moving laterally towards the tea cake, pushing the tea cake at the top of the first limiting cylinder 14 onto the conveyor belt 92, where it is transported by the conveyor belt 92. The tea leaves are moved to the next processing station. At the same time, the tea leaves in the second limiting cylinder 15 are steamed. The rotary motor 21 drives the rotating rod 24 to rotate 180° again, so that the positions of the second limiting cylinder 15 and the first limiting cylinder 14 are exchanged again. The second limiting cylinder 15 is located in the tea pressing section 13, and the first limiting cylinder 14 is located in the tea steaming section 12. Then, the timed and quantitative feeding hopper 83 feeds the first limiting cylinder 14 for the third time. Then, the tea pressing and tea steaming operations are carried out automatically at the same time, thereby realizing the automation of feeding, steaming, pressing and discharging.

[0053] According to this embodiment, an automatic tea pressing and forming device drives two limiting cylinders to slide synchronously and interchange positions within an annular groove on the base via a rotating mechanism. This allows the steaming and pressing processes to be performed simultaneously, eliminating waiting time between steaming and pressing, significantly improving production efficiency and achieving continuous automated operation. The ejection mechanism, in conjunction with the pushing mechanism, automatically ejects the tea cake from the pressing cylinder to the top of the limiting cylinder and pushes it out laterally after pressing, achieving automatic demolding and discharge without manual intervention, significantly reducing labor intensity. By configuring a timed and quantitative feeding mechanism, the amount of tea added to the steaming section each time can be precisely controlled, ensuring the consistency of weight for each batch of tea cakes and improving product standardization and quality stability. The equipment has a compact structure, with steaming, position interchange, pressing, ejection, and pushing actions operating in a coordinated manner. It is easy to operate and can stably achieve automated production of feeding, steaming, pressing, and discharging.
