Description

Technical Field

[0001] This utility model relates to the technical field of tea processing equipment, and in particular to a tea pressing device. Background Technology

[0002] Compressed tea is a type of tea product made by steaming loose tea leaves and then pressing them into specific shapes such as cakes or bricks using molds. Compressed tea not only facilitates long-term storage and transportation but also creates a suitable environment for microbial fermentation after pressing, which is beneficial for the continuous improvement of tea quality during post-fermentation. This is especially true for fermented teas such as Pu-erh tea and black tea, where pressing into cakes, bricks, or tuocha (bowl-shaped tea cakes) has become a key processing step. During the pressing process, the stability of the pressing device, the uniformity of the pressing force, and the adaptability of the mold directly determine the forming effect, internal compactness, and subsequent quality performance of the tea cake.

[0003] Existing pressing devices typically use bolt-locking or simple clamping methods to fix the molds, lacking a rapid adjustment and locking mechanism. When pressing tea cakes of different sizes or shapes, operators must manually disassemble the original mold, reposition and fix the new mold, a cumbersome and time-consuming process that severely impacts processing efficiency. Furthermore, due to the lack of effective mold positioning and clamping structures, the molds are prone to shifting or loosening during pressing, leading to uneven tea cake forming and loose edges, affecting product consistency. While some devices possess some adjustment capabilities, the adjustment range is limited, operation is inconvenient, and they cannot achieve rapid switching and reliable fixing of multiple molds, making them unsuitable for the demands of modern tea production involving small batches and multiple varieties. Utility Model Content

[0004] This utility model provides a tea pressing device to solve the problem that the existing tea pressing devices are cumbersome and time-consuming when changing the original mold to press tea cakes of different specifications or shapes, which seriously affects the processing efficiency.

[0005] This utility model provides a tea pressing device, including a worktable, a support frame installed at the bottom of the worktable, a pair of slide rails installed at the top of the worktable, a sliding sleeve slidably connected to the top of the slide rails, a sliding plate installed at the top of the sliding sleeve, side plates installed on both sides of the top of the sliding plate, slide rods installed on both sides inside the side plates, clamping plates slidably connected to the outer sides of the slide rods, a pressing mold provided between the pair of clamping plates, an ejector plate provided at the bottom of the inner part of the pressing mold, an adjusting mechanism for adjusting the distance between the pair of clamping plates provided on one side of the side plate, a translation mechanism for moving the sliding plate installed at the top of the worktable, a gantry frame installed at the top of the worktable, a pressing mechanism installed at the top of the gantry frame, and a first electric telescopic rod installed at the bottom of the worktable on the side away from the translation mechanism, the output end of the first electric telescopic rod extending to the bottom of the ejector plate.

[0006] Optionally, the adjusting mechanism includes a bidirectional threaded rod, with retainers rotatably connected to both ends of the bidirectional threaded rod. One side of each pair of retainers is fixedly connected to one side of the side plate. Movable blocks are fitted onto both ends of the bidirectional threaded rod, with one side of each movable block fixedly connected to one side of the clamping plate. An adjusting knob is installed at one end of the bidirectional threaded rod.

[0007] Optionally, the translation mechanism includes a second electric telescopic rod, with retaining seats fitted at both outer ends of the second electric telescopic rod. The bottom end of the retaining seat is fixedly connected to one side of the top of the worktable, and the output end of the second electric telescopic rod is fixedly connected to one side of the sliding plate.

[0008] Optionally, the pressing mechanism includes a hydraulic rod, one end of which is fixedly connected to the top of the gantry frame, the output end of which passes through the inner top of the gantry frame, and a pressure plate is installed at the output end of the pressing mechanism.

[0009] Optionally, the top of the sliding plate is provided with a first ejection hole, and the bottom of the pressing mold is provided with a second ejection hole.

[0010] Optionally, support bases are installed at the four corners of the bottom of the support frame, and the bottom of the support bases is provided with anti-slip texture.

[0011] Optionally, a control panel is installed on one side of the workbench.

[0012] The beneficial effects of the tea cake pressing device provided by this utility model are as follows:

[0013] 1. By integrating the adjustable mold clamping mechanism (side plate, slide bar, clamping plate, adjustable distance mechanism), the linear transfer mechanism (slide rail, slide sleeve, translation mechanism) and the pressing and demolding mechanism (gantry frame, pressing mechanism, ejection plate, first electric telescopic rod) onto a single workbench, a complete and continuous operation from mold fixing, filling, transfer, pressing to ejection and demolding is achieved, reducing intermediate links and manual operation time, and improving the efficiency of pressing and processing tea materials.

[0014] 2. By adopting a mechanical adjustment mechanism consisting of a bidirectional threaded rod, a retainer, and a movable block, the two clamping plates can be driven to move synchronously in opposite directions or in opposite directions by rotating a single adjustment knob. This achieves rapid and precise adaptation to pressing molds of different shapes and sizes, and utilizes the self-locking characteristics of the threads to provide stable and reliable clamping force, effectively preventing the mold from loosening or shifting during the pressing process, and ensuring the consistency of tea cake forming quality.

[0015] 3. By opening the first ejection hole and the second ejection hole at corresponding positions on the sliding plate and the bottom of the pressing mold respectively, the power output end of the ejection mechanism (first electric telescopic rod) can directly act on the ejection plate inside the mold, so as to smoothly and completely eject the formed tea cake from the mold cavity after pressing, achieve rapid demolding and avoid damage to the tea cake structure that may be caused by manual prying.

Detailed Implementation

[0024] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions in the embodiments of this utility model are described clearly and completely below. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are also within the scope of protection of this utility model.

[0025] like Figure 1-5 As shown, this utility model provides a tea pressing device, including a workbench 1, a support frame 2 installed at the bottom of the workbench 1, a pair of slide rails 4 installed at the top of the workbench 1, a sliding sleeve 5 slidably connected to the top of the slide rails 4, a sliding plate 6 installed at the top of the sliding sleeve 5, side plates 7 installed on both sides of the top of the sliding plate 6, slide rods 8 installed on both sides inside the side plates 7, clamping plates 9 slidably connected to the outside of the slide rods 8, a pressing mold 14 is provided between the pair of clamping plates 9, an ejector plate 15 is provided at the bottom of the inside of the pressing mold 14, an adjusting mechanism 10 for adjusting the distance between the pair of clamping plates 9 is provided on one side of the side plate 7, a translation mechanism 13 for moving the sliding plate 6 is installed at the top of the workbench 1, a gantry frame 11 is installed at the top of the workbench 1, a pressing mechanism 12 is installed at the top of the gantry frame 11, and a first electric telescopic rod 16 is installed at the bottom of the workbench 1 on the side away from the translation mechanism 13, the output end of the first electric telescopic rod 16 extends to the bottom end of the ejector plate 15.

[0026] The main structure of the compressed tea cake pressing device includes a worktable 1, an adjusting mechanism 10, a pressing mechanism 12, a translation mechanism 13, and a pressing mold 14. The worktable 1 provides support for the entire compressed tea cake pressing device, and all other components are mounted on it. The worktable 1 cooperates with its bottom support frame 2 to create a stable working platform for the pressing operation. The pressing mold 14 is clamped and secured by two clamping plates 9. The distance between the two clamping plates 9 is adjusted and controlled by the adjusting mechanism 10 to accommodate pressing molds 14 of different sizes. The distance between the two clamping plates 9 is adjusted by the adjusting mechanism 10, and during the adjustment process, the side plate 7 and the sliding rod 8 cooperate to guide the moving clamping plates 9. The sliding plate 6 is used to place the pressing mold 14 and is driven by the translation mechanism 13 in conjunction with the slide rail 4 and the sliding sleeve 5, thereby moving the pressing mold 14 to directly below the pressing mechanism 12 or to the material picking position. The pressing mechanism 12 is fixed by the gantry frame 11 to ensure stable transmission of pressing force. The pressing mechanism 12 presses and shapes the tea material in the pressing mold 14, tightly pressing the tea cake. After pressing, the first electric telescopic rod 16 pushes the ejector plate 15 to eject the pressed tea cake from the pressing mold 14, realizing automatic demolding.

[0027] The working process of the tea pressing device is as follows: When preparing to press the tea material, first select a pressing mold 14 of appropriate size according to the needs, and then place it on the sliding plate 6. After placing the pressing mold 14, adjust the distance between the two clamping plates 9 through the adjusting mechanism 10 to secure the pressing mold 14 and prevent it from shaking during movement and pressing. After fixing the pressing mold 14, place the tea material into it, and then drive the sliding plate 6 to move through the translation mechanism 13. The sliding plate 6 carries the pressing mold 14 to directly below the pressing mechanism 12, and then the pressing mechanism 12 can press the tea material in the pressing mold 14. After pressing, remove the pressed tea cake, and repeat the above process to continuously press the tea material. When it is necessary to change the pressing mold 14, the pressing mold 14 can be quickly changed through the coordinated action of the side plate 7, the sliding rod 8, the clamping plate 9 and the adjusting mechanism 10, which is convenient and quick.

[0028] The tea pressing device provided by this utility model can quickly switch between various molds and reliably fix them according to the needs of the production process, which is convenient and fast and improves the efficiency of pressing tea materials.

[0029] like Figure 3 and Figure 5 As shown, the adjusting mechanism 10 further includes a bidirectional threaded rod 1001, with retainers 1002 rotatably connected to both ends of the bidirectional threaded rod 1001. One side of each pair of retainers 1002 is fixedly connected to one side of the side plate 7. Movable blocks 1003 are fitted onto both ends of the bidirectional threaded rod 1001. One side of the movable block 1003 is fixedly connected to one side of the clamping plate 9. An adjusting knob 1004 is installed at one end of the bidirectional threaded rod 1001.

[0030] The bidirectional threaded rod 1001 in the adjusting mechanism 10 cooperates with the retainer 1002, ensuring that the threaded rod does not deviate during rotation. The rotation of the bidirectional threaded rod 1001 drives the movable blocks 1003 at both ends to move synchronously relative to or towards each other, thereby causing the clamping plate 9 to slide along the slide bar 8, achieving precise adjustment of the mold clamping distance. The adjusting knob 1004 provides a convenient point of force application for the operator, allowing for manual adjustment without tools. This quickly adapts to different internal sizes of the pressing mold 14, such as round and square molds, ensuring that the mold does not wobble during pressing and improving the tea cake forming accuracy.

[0031] like Figure 3 As shown, the translation mechanism 13 further includes a second electric telescopic rod 1301. Both outer ends of the second electric telescopic rod 1301 are fitted with retaining seats 1302. The bottom end of the retaining seat 1302 is fixedly connected to one side of the top of the worktable 1. The output end of the second electric telescopic rod 1301 is fixedly connected to one side of the sliding plate 6.

[0032] The second electric telescopic rod 1301 in the translation mechanism 13 provides power to directly drive the sliding plate 6 to slide along the slide rail 4, thereby realizing the automatic adjustment of the mold position. The electric telescopic rod is fixed by the retaining seat 1302 to prevent it from shifting during extension and retraction.

[0033] like Figure 2 As shown, the pressing mechanism 12 further includes a hydraulic rod 1201, one end of which is fixedly connected to the top of the gantry frame 11, the output end of the hydraulic rod 1201 passes through the inner top of the gantry frame 11, and a pressure plate 1202 is installed at the output end of the pressing mechanism 12.

[0034] The hydraulic rod 1201 in the pressing mechanism 12 provides strong and controllable pressing force to meet the processing requirements of tea cakes with different degrees of compaction. The pressure plate 1202 at the output end of the hydraulic rod 1201 cooperates with the pressing mold 14 to evenly compress and shape the tea material, avoiding uneven thickness of the tea cake.

[0035] It should be noted that the top end of the pressure plate 1202 and the bottom end of the hydraulic rod 1201 are detachably connected, for example, through threads or screw holes, which is not limited here. When changing the pressing mold 14, the pressure plate 1202 that is compatible with the pressing mold 14 needs to be replaced simultaneously.

[0036] like Figure 4 As shown, the top of the sliding plate 6 is provided with a first ejection hole 601, and the bottom of the pressing mold 14 is provided with a second ejection hole 1401.

[0037] The first ejection hole 601 at the top of the sliding plate 6 is aligned with the second ejection hole 1401 at the bottom of the pressing mold 14, providing a through channel for the output end of the first electric telescopic rod 16, so that the telescopic rod can directly act on the ejection plate 15, thereby ejecting the pressed tea cake in the pressing mold 14 to complete the demolding.

[0038] like Figure 1 and Figure 2 As shown, furthermore, support bases 3 are installed at the four corners of the bottom of the support frame 2, and the bottom of the support bases 3 are provided with anti-slip texture. Furthermore, a control panel 17 is installed on one side of the workbench 1.

[0039] By installing support bases 3 at each of the four corners of the bottom of the support frame 2, the stability of the device is improved. Through the control panel 17 on one side of the workbench 1, operators can centrally set the pressing parameters, achieving automated control of the pressing process.

[0040] like Figure 1-5 As shown, the complete working principle of the tea cake pressing device provided by this utility model is as follows:

[0041] In use, a stable platform for pressing tea cakes is built on the workbench 1, supporting core components such as the slide rail 4 and the gantry frame 11, ensuring that the overall structure does not shift during pressing. The workbench 1 is supported by the support frame 2, raising the working height to suit the operator's working habits. The slide rail 4 cooperates with the sliding sleeve 5 to achieve smooth sliding of the sliding plate 6, driving the pressing mold 14 to move precisely. The clamping plate 9 is supported by the side plate 7 and the sliding rod 8, providing guidance for mold fixation. The spacing of the clamping plate 9 is adjusted by the adjusting mechanism 10 to accommodate pressing molds 14 of different specifications. The sliding plate 6 is moved by the translation mechanism 13, transporting the mold to directly below the pressing mechanism 12 or to the material removal position. The pressing mechanism 12 is fixed by the gantry frame 11 to ensure stable transmission of pressing force. The pressing mechanism 12 presses and shapes the tea material to form a tightly pressed tea cake. The first electric telescopic rod 16 pushes the ejector plate 15 to eject the pressed tea cake from the mold, achieving automatic demolding.

[0042] The bidirectional threaded rod 1001 in the adjusting mechanism 10 cooperates with the retainer 1002, ensuring that the threaded rod does not deviate during rotation. The rotation of the bidirectional threaded rod 1001 drives the movable blocks 1003 at both ends to move synchronously relative to or towards each other, thereby causing the clamping plate 9 to slide along the slide bar 8, achieving precise adjustment of the mold clamping distance. The adjusting knob 1004 provides a convenient point of force application for the operator, allowing for manual adjustment without tools. This quickly adapts to different internal sizes of the pressing mold 14, such as round and square molds, ensuring that the mold does not wobble during pressing and improving the tea cake forming accuracy.

[0043] Power is provided by the second electric telescopic rod 1301 in the translation mechanism 13, which directly drives the sliding plate 6 to slide along the slide rail 4, thereby realizing the automatic adjustment of the mold position. The electric telescopic rod is fixed by the retaining seat 1302 to prevent it from shifting during extension and retraction.

[0044] The hydraulic rod 1201 in the pressing mechanism 12 provides strong and controllable pressing force to meet the processing requirements of tea cakes with different compression levels. The pressure plate 1202 at the output end of the hydraulic rod 1201 cooperates with the pressing mold 14 to evenly compress and shape the tea material, avoiding uneven thickness of the tea cake. The first ejection hole 601 at the top of the sliding plate 6 is aligned with the second ejection hole 1401 at the bottom of the pressing mold 14, providing a through channel for the output end of the first electric telescopic rod 16, so that the telescopic rod can directly act on the ejection plate 15.

[0045] With support bases 3 installed at the four corners of the bottom of the support frame 2, the stability of the device is improved. Through the control panel 17 on one side of the workbench 1, the operator can centrally set the pressing parameters to realize the automated control of the pressing process. This utility model can effectively realize the continuous operation of pressing tea from mold fixing, tea material pressing to demolding and material removal, improve processing efficiency and tea cake forming quality, and has high practical value.

[0046] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and not to limit it; although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features; and these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model.
