Description

Technical Field

[0001] This utility model relates to the technical field of tea rolling machines, specifically to a tea rolling machine with adjustable pressure. Background Technology

[0002] In the tea production process, rolling is a crucial step that has a decisive impact on the quality of tea. Through rolling, tea leaves are not only shaped into a tightly rolled and curved form, making them easier to store and brew, but the rolling process also moderately breaks down the leaf tissue, promoting the transformation of substances within the tea leaves and enhancing their color, aroma, and flavor.

[0003] When performing tea rolling operations, a corresponding tea rolling machine is usually used. There are many types of tea rolling machines on the market. For example, the utility model patent with authorization announcement number CN221152829U discloses a tea rolling machine with adjustable rolling pressure function, including: a main body component, including a support foot, a load-bearing plate connected between three sets of the support foot, a rolling disc connected to the load-bearing plate, and a rib connected to the rolling disc; an adjustment component, including a movable hole opened on the rolling disc, a support frame connected below the rib, a rotating shaft rotatably connected to the side of the load-bearing plate, a self-locking crank handle rotatably connected to the rotating shaft, a first bevel gear connected to the other end of the rotating shaft, and a second bevel gear rotatably connected to the first bevel gear. This utility model solves the problem of multiple sets of ring-shaped ribs on the kneading pan. The function of these ribs is to provide friction during kneading. The higher the ribs, the greater the friction and the more serious the breakage rate. Conversely, the lower the ribs, the lower the breakage rate. Therefore, high ribs are better for making black tea, and low ribs are better for making green tea. The existing ribs are directly welded to the kneading pan and cannot be adjusted according to the actual situation, which reduces the applicability of the kneading machine.

[0004] While the aforementioned technical solutions have their advantages, most adjustable-pressure tea rolling machines currently in use still have some shortcomings. For example, their pressure adjustment mainly relies on the ribs extending beyond the height of the rolling disc, combined with the distance between the ribs and the rolling drum, to provide different frictional forces and achieve the pressure adjustment effect. However, as the ribs are adjusted, gaps may exist between the ribs and the bottom and sides of the rolling disc due to the sliding fit. These gaps can cause tea leaves to remain in the gap areas, affecting the processing effect. Therefore, we propose an adjustable-pressure tea rolling machine. Utility Model Content

[0005] The purpose of this invention is to provide an adjustable pressure tea rolling machine to solve the defects mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] An adjustable pressure tea rolling machine includes a main body and a rolling disc that can be raised and lowered on the main body. A support frame is fixedly installed between multiple supports at the bottom of the main body. A cylinder is fixedly installed at a corresponding position on the support frame. The telescopic shaft end of the cylinder is detachably installed on the bottom surface of the rolling disc. Multiple storage sleeves are provided below the rolling disc.

[0035] Please see Figures 1-4 This utility model provides a technical solution: an adjustable pressure tea kneading machine, including a tea kneading machine body 1 and a kneading disc 2 that can be lifted and lowered on the tea kneading machine body 1. A support frame 10 is fixedly installed between multiple supports at the bottom of the tea kneading machine body 1. A cylinder 3 is fixedly installed at a corresponding position on the support frame 10. The end of the telescopic shaft of the cylinder 3 is detachably installed on the bottom surface of the kneading disc 2. Multiple storage sleeves 4 are provided below the kneading disc 2. Multiple racks 5 are fixedly installed on the bottom surface of the kneading disc 2. The racks 5 are located inside the storage sleeves 4 and are slidably connected to the storage sleeves 4. There are three racks 5 and three storage sleeves 4, which are distributed in a ring on the bottom surface of the kneading disc 2 to achieve a stable support effect.

[0036] A side guide sleeve 41 is fixedly installed on the side of the storage sleeve 4. A conical locking block 44 for limiting the position of the rack 5 is slidably connected inside the side guide sleeve 41. A fastening bolt 45 for limiting the left and right movement of the conical locking block 44 is threadedly connected to the top plate of the storage sleeve 4. By setting up the cylinder 3, rack 5 and storage sleeve 4, the cylinder 3 drives the kneading disc 2 to rise and fall to adjust the distance between the kneading disc 2 and the kneading barrel on the main body 1 of the tea kneading machine, thereby adjusting the kneading pressure. The rack 5 slides and guides in the inner cavity 40 of the storage sleeve 4, replacing the traditional method of adjusting the pressure by adjusting the height of the ribs, avoiding gaps between the ribs and the kneading disc, so that tea leaves will not remain in the gaps and ensuring the preparation effect.

[0037] In this embodiment, a rectangular plate 30 is fixedly installed at the end of the telescopic shaft of the cylinder 3. The rectangular plate 30 is detachably installed on the bottom surface of the kneading disc 2 by multiple fastening bolts, which facilitates the disassembly and maintenance of the cylinder 3 and the kneading disc 2 and reduces the difficulty of equipment maintenance.

[0038] Specifically, the support frame 10 is located around the discharge port of the kneading disc 2, and the cylinder 3 and the rack 5 are both located at the discharge port of the kneading disc 2 away from it, so that the device will not affect the normal unloading operation of the kneading machine.

[0039] Furthermore, the storage sleeve 4 is provided with an inner cavity 40 arranged along the length of the storage sleeve 4, and the rack 5 is located in the inner cavity 40 and is slidably connected to the inner cavity 40, so that the rack 5 can slide normally in the storage sleeve 4.

[0040] like Figure 3 As shown, multiple teeth 50 are provided on the side of the rack 5, and a snap-fit ​​gap 51 is provided between two adjacent teeth 50. The conical snap-fit ​​block 44 engages with the snap-fit ​​gap 51 to limit the rack 5.

[0041] like Figure 3 and Figure 4 As shown, a sliding chamber 411 is provided inside the side guide sleeve 41, and an inner slider 43 is slidably connected inside the sliding chamber 411. A conical block 44 is integrally formed on the side of the inner slider 43. A slide rod 42 is fixedly installed on the rear side of the inner slider 43, which extends through the side guide sleeve 41 and is slidably connected to the side guide sleeve 41. This makes the conical block 44 and the inner slider 43 slide more stably and smoothly. The slide rod 42 is convenient for manual operation to adjust the conical block 44 to move back and forth.

[0042] In addition, the size of the inner slider 43 is adapted to the size of the sliding chamber 411, so that the inner slider 43 can slide stably in the sliding chamber 411 and is not prone to shaking; a handle ring 422 is fixedly installed at the end of the slide rod 42 that protrudes from the side guide sleeve 41, making it easier for people to operate by holding the handle ring 422.

[0043] It is worth noting that multiple slots 421 are provided on the top surface of the slide bar 42, and a limiting pin 46 is fixedly installed at the bottom end of the fastening bolt 45. The limiting pin 46 and the slot 421 engage with each other to limit the slide bar 42, thereby limiting the rack 5 and ensuring that the kneading disc 2 remains stable after the height is adjusted. In addition, the distance between two adjacent engagement gaps 51 is between 3mm and 6mm, which makes the adjustment range of the kneading disc 2 more precise when it is adjusted up and down.

[0044] It is worth noting that a fixed base 47 is fixedly installed at the bottom of the storage sleeve 4. The fixed base 47 is fixedly installed on the external base, providing stable support for the sliding cooperation between the storage sleeve 4 and the rack 5, preventing shaking when the kneading plate 2 is raised and lowered, and improving the stability of the equipment operation.

[0045] In this embodiment, the ribs inside the kneading disc 2 are directly fixed to the bottom wall of the kneading disc 2. By directly adjusting the up and down position of the kneading disc 2, the distance between the kneading disc 2 and its internal ribs and the kneading drum on the external kneading machine can be further adjusted, thereby achieving the effect of adjustable kneading pressure.

[0046] Finally, it should be noted that the cylinder 3, the corresponding air source, the corresponding PLC control system, and the external power supply of this utility model are all general standard parts or parts known to those skilled in the art. Their structure and principle can be known to those skilled in the art through technical manuals or conventional experimental methods. In the idle space of this device, all the above-mentioned electrical components, which refer to power elements, electrical components, and the matching controller and power supply, are connected by wires. The specific connection method should refer to the working principle of this utility model. The electrical connections between each electrical component are completed in the order of operation. The detailed connection methods are all technologies known in the art.

[0047] When using the adjustable pressure tea kneading machine of this utility model, the storage sleeve 4 is fixed to the external base through the fixed base 47, the support frame 10 is fixed between the bottom supports of the tea kneading machine body 1, the cylinder 3 is installed on the support frame 10, the rectangular plate 30 is connected to the bottom surface of the kneading disc 2 by fastening bolts, and the rack 5 is correspondingly embedded in the inner cavity 40 of the storage sleeve 4 to ensure that each component is assembled in place;

[0048] During pressure adjustment, the kneading pressure is determined according to the type of tea. The cylinder 3 is started to drive the kneading disc 2 to rise and fall, and the distance between the kneading disc 2 and the kneading barrel on the kneading machine is adjusted. The accuracy of this distance adjustment can be controlled by the PLC control system built into the cylinder 3. The rack 5 slides and guides the kneading disc 2 in the storage sleeve 4. After reaching the target height, the handle ring 422 is held to push the slide rod 42, which drives the inner slider 43 to slide in the sliding chamber 411 of the side guide sleeve 41, so that the conical block 44 is engaged in the engagement gap 51 of the rack 5. Then the fastening bolt 45 is tightened to allow the limiting insert 46 to be embedded in the slot 421 of the slide rod 42, thus completing the limiting.

[0049] During the rolling process, the tea leaves are processed between the rolling pan 2 and the rolling barrel. The support frame 10, cylinder 3 and rack 5 are all located away from the discharge port, so as not to affect the unloading.

[0050] The foregoing has shown and described the basic principles, main features, and advantages of this utility model.
