Description

Technical Field

[0001] This utility model relates to the field of tea processing technology, and in particular to a drying device for tea processing. Background Technology

[0002] Tea drying refers to one of the drying methods in the drying process of tea leaves after they have been withered and rolled. Drying is the last step in most tea processing, mainly to dry the tea leaves, enhance their aroma, and make them easier to preserve. In modern processes, special drying equipment is usually used to dry tea leaves.

[0003] A search revealed a drying device for tea processing in patent document CN220206301U, comprising a heating device for drying tea and a drum for uniformly heating the tea. The inner wall of the drum is fixedly connected to several evenly distributed heating devices. Rollers for rotation are fixedly welded to both ends of the outer circumference of the drum. Connecting plates are fixedly welded to the outer sides of the rollers. Two connecting strips for fixed support are fixedly connected to the top of the connecting plates. A horizontal plate is fixedly welded to the top of the connecting strips. A drive motor is screwed to the top of the horizontal plate. A drive gear is fixedly connected to the output shaft of the drive motor. A toothed belt is meshed with the drive gear and fixedly connected to the outer circumference of the drum. By controlling the rotation of the drive motor, the drive gear connected to its output shaft meshes with the toothed belt set on the outer circumference of the drum, thereby driving the drum to rotate and turning the tea placed inside the drum, thus improving the drying efficiency and quality of the tea.

[0004] Based on the above search and combined with existing technology, most existing tea drying devices are equipped with a screen structure (such as the collection box in the aforementioned patent document) to ensure air permeability during the tumbling process of tea drying and to remove broken tea or tea residue, resulting in a more perfect appearance of the dried tea. However, in actual use, it has been found that tea leaves easily get stuck in the mesh of the screen structure during the tumbling process, clogging the mesh and reducing the effectiveness of removing tea residue. At the same time, since tea leaves are usually curved and thin, it is difficult for tea leaves inserted into the mesh of the screen structure to fall off by tumbling. During repeated tumbling, they may get hooked and entangled with other tea leaves, and even whole tea leaves may break, increasing the damage rate of the tea leaves and reducing the yield of qualified tea products after drying. Therefore, there is a need for a tea drying device. Utility Model Content

[0005] The purpose of this application is to provide a drying apparatus for tea processing to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this application provides the following technical solution: a drying device for tea processing, including a drying box, with a feeding port and a discharge port respectively provided at the upper and lower ends of the drying box, a drying plate embedded in the bottom wall of the drying box, a servo motor fixed on one side of the drying box, a drive shaft connected to the output shaft of the servo motor, the end of the drive shaft away from the servo motor rotating through the side wall of the drying box and rotatingly connected to the side wall of the other side of the drying box, and a drying barrel for filling tea is fixedly sleeved on the servo motor;

[0007] The drying drum is equipped with multiple main screen holes, which are arranged in rows along the axis of the drying drum, and the multiple rows of main screen holes are evenly distributed along the circumference of the drying drum.

[0008] A flexible inner liner is fixed inside the drying drum. The flexible inner liner has multiple secondary screen holes that correspond one-to-one with the main screen holes. The fixing points of the flexible inner liner and the drying drum are staggered with the positions of the secondary screen holes.

[0009] The drying drum is also equipped with multiple elongated impact holes, which are located between two adjacent rows of main screen holes, and the positions of the impact holes and the main screen holes are consistent in the circumferential direction.

[0010] Inside the drying oven, there is also a movable follower rod, on which are fixed multiple hammer rods that correspond one-to-one with multiple long striking holes in the same row;

[0011] The drying oven is also equipped with a follower structure that drives the follower rod to move. The follower structure rotates with the rotation of the drive shaft and drives the follower rod away from the drying drum or quickly approach the drying drum. When the follower rod quickly approaches the drying drum, the hammer rod moves and inserts into the long striking hole and hammers the outer wall of the flexible inner liner.

[0012] The direction of movement of the follower rod is consistent with the radial direction of the drying drum.

[0013] Preferably, the side walls on both sides of the drying oven are provided with sliding grooves, the extension direction of the sliding grooves is consistent with the radial direction of the drying drum, and the two ends of the follower rod are slidably connected in the two sliding grooves respectively.

[0014] The follow-up structure includes a drive disk, two drive disks are provided and fixedly sleeved on both ends of the drive shaft, and multiple first guide blocks are fixed on the drive disk. The multiple first guide blocks are evenly distributed along the periphery of the drive disk. Each first guide block has an arc-shaped guide surface and a side wall extending in the same direction as the radial direction of the drying drum.

[0015] The chute is also equipped with a reset component for applying compressive stress to the follower rod, which ensures that the follower rod always tends to move toward the axis of the drying drum.

[0016] When the drive disc rotates with the drive shaft, the arc-shaped guide surface of the first guide block first contacts the follower rod and lifts the follower rod, so that the hammer rod moves along the extension direction of the slide groove and leaves the striking hole. When the follower rod moves to the side wall of the first guide block and separates from the first guide block, the hammer rod is quickly inserted into the striking hole under the action of the reset member and hammers the outer wall of the flexible inner liner.

[0017] Preferably, the reset component includes a compression spring, one end of which is fixed to the inner side of the slide groove away from the drying drum, and the other end of which is fixed to the peripheral side of the follower rod away from the drying drum.

[0018] Preferably, the drying drum has an opening for taking out and putting in, which extends along the axial direction of the drying drum. A cylinder cover is hinged and closed inside the opening, and the other end of the cylinder cover is movably engaged with the drying drum by a limiting member.

[0019] The cylinder cover also has a main sieve hole and a striking hole.

[0020] Preferably, there are empty areas on both sides of the drying drum where the main sieve holes and percussion holes are not opened;

[0021] A second guide block is fixed at the position of the empty area on the periphery of the drive disc. The second guide block covers the empty area and the main screen hole area on the cylinder cover by the stroke of the follower rod.

[0022] Preferably, a limiting elongated hole is provided on the cylinder cover, and the limiting elongated hole extends along the axial direction of the drying cylinder;

[0023] The limiting component includes a rotating limiting rod, which is a long rod that can move through the limiting elongated hole. The lower end of the rotating limiting rod is rotatably connected to the side wall of the drying drum through a shaft column, and the diameter of the shaft column is smaller than the width of the limiting elongated hole.

[0024] Rotate the limiting rod so that the side wall near the axis of the drying drum abuts against the outer wall of the drum cover.

[0025] In summary, the technical effects and advantages of this utility model are as follows:

[0026] 1. In this utility model, a follower structure drives a follower rod away from or rapidly towards the drying drum. When the follower rod rapidly approaches the drying drum, the hammer rod moves and inserts into the striking hole, striking the outer wall of the flexible inner liner. This causes the flexible inner liner to deform inward, affecting the deformation of the two secondary screen holes adjacent to the striking hole. This deformation is mainly manifested as an inward expansion of the sidewalls. As a result, the tea leaves stuck in the main and secondary screen holes, after being freed from the obstruction, move inward under the impact of the deformation of the flexible inner liner, thus removing the stuck tea leaves from the main and secondary screen holes. This achieves the cleaning of the screen holes during the drying process, ensuring a consistently stable efficiency in removing broken tea and tea residue, and improving the sieving effect. At the same time, because the flexible inner liner is made of flexible material, the impact between it and the tea leaves during deformation is also flexible. Therefore, when cleaning tea leaves that clog the screen holes, the integrity of the tea leaves can be largely guaranteed, avoiding the generation of broken tea leaves, ensuring the quality of the dried tea leaves, improving the finished product qualification rate, reducing losses during the drying process, and thus reducing production costs.

[0027] 2. In this utility model, by setting the second guide block, when the empty area rotates into the hammer rod area, the follower rod is always driven away from the drying drum by the second guide block, and ensures that the follower rod can move closer to the cylinder cover again after leaving the empty area and hammer the flexible inner liner covering the inside of the cylinder cover, so as to clean the main screen holes and corresponding secondary screen holes on the cylinder cover.

[0036] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0037] Example: Reference Figure 1-6 The drying device for tea processing shown includes a drying box 1. The upper and lower ends of the drying box 1 are respectively provided with a feeding port 11 and a feeding port 12. A dustproof net 13 is also hinged and covered on the feeding port 11, which can achieve the effect of air permeability and dust prevention, which is beneficial to drying tea. A drying plate (not shown in the figure) is embedded in the bottom wall of the drying box 1. The drying plate adopts the resistance heating plate or ceramic heating plate (device) commonly used in the prior art and suitable for this embodiment, which can efficiently dry tea. A servo motor 3 is fixed on one side of the drying box 1. The output shaft end of the servo motor 3 is driven and connected to a drive shaft 31. The end of the drive shaft 31 away from the servo motor 3 rotates through the side wall of the drying box 1 and is rotatably connected to the side wall of the other side of the drying box 1. A drying barrel 2 for filling tea is fixedly sleeved on the servo motor 3.

[0038] The drying drum 2 is provided with multiple main screen holes 21, which are arranged in rows along the axial direction of the drying drum 2, and the multiple rows of main screen holes 21 are evenly distributed along the circumference of the drying drum 2.

[0039] A flexible inner liner 5 is fixed inside the drying barrel 2. The flexible inner liner 5 is made of an elastic material commonly used in the prior art and suitable for this embodiment (such as silicone rubber, polyimide and some alloy materials, the best of which will not affect the quality of the dried tea). It has good heat resistance and elastic deformation performance. The flexible inner liner 5 is provided with a number of secondary sieve holes 51 that correspond one-to-one with a number of main sieve holes 21. The fixing point of the flexible inner liner 5 and the drying barrel 2 and the position of the secondary sieve holes 51 are staggered.

[0040] The drying drum 2 is also provided with multiple elongated impact holes 22, which are located between two adjacent rows of main screen holes 21, and the positions of the impact holes 22 and the main screen holes 21 are consistent in the circumferential direction.

[0041] Inside the drying oven 1, a follower rod 6 is also movably installed. On the follower rod 6, there are a number of hammer rods 61 that correspond one-to-one with a number of long striking holes 22 in the same row.

[0042] The drying oven 1 is also equipped with a follower structure that drives the follower rod 6 to move, wherein the direction of movement of the follower rod 6 is consistent with the radial direction of the drying drum 2;

[0043] Based on the above structure, combined with Figure 2 , Figure 3 and Figure 6 It can be seen that the follower structure rotates with the rotation of the drive shaft 31, and drives the follower rod 6 away from the drying barrel 2 or quickly approach the drying barrel 2. When the follower rod 6 quickly approaches the drying barrel 2, the hammer rod 61 moves into the striking hole 22 and hammers the outer wall of the flexible inner liner 5, thereby causing the flexible inner liner 5 to deform inward, and causing the two auxiliary sieve holes 51 adjacent to the striking hole 22 to be affected and deformed, mainly manifested as the inward expansion deformation of the side wall, so that the tea stuck in the main sieve hole 21 and the auxiliary sieve hole 51 can be removed from the wall (mainly referring to the inner wall of the auxiliary sieve hole 51, because the tea is inside the flexible inner liner 5, therefore, when the tea is stuck...). After being stuck in the secondary screen hole 51, the tea leaves move inward under the deformation and impact of the flexible inner liner 5, thereby causing the stuck tea leaves to leave the main screen hole 21 and the secondary screen hole 51. This achieves the cleaning operation of the screen holes during the drying process, ensuring that the efficiency of removing broken tea and tea residue remains stable and improving the screening effect. At the same time, since the flexible inner liner 5 is made of flexible material, the impact between it and the tea leaves when it deforms is also flexible. Therefore, when cleaning the tea leaves that are blocking the screen holes, the integrity of the tea leaves can be largely guaranteed, avoiding the generation of broken tea leaves, ensuring the quality of the dried tea leaves, improving the finished product qualification rate, reducing losses during the drying process, and thus reducing production costs.

[0044] In addition, by Figures 2-4 It can be understood that in this embodiment, the follower rod 6 is installed above the drying drum 2, which ensures that the tea leaves being cleaned are those stuck in the sieve holes (i.e., the main sieve hole 21 and the secondary sieve hole 51). Only tea leaves stuck in the sieve holes can be rotated to the top of the drying drum 2, ensuring the effectiveness of the cleaning and preventing ineffective or improper cleaning due to the follower rod 6 being installed below. In addition, the operator can also install the follower rod 6 at the top front side of the rotation direction of the drying drum 2 according to actual usage needs (e.g., ...). Figure 3 As shown in the image, this method ensures that the tea leaves are cleaned only after they have passed the highest point without falling, further guaranteeing the effectiveness of the cleaning and improving the cleaning results.

[0045] Furthermore, the side walls on both sides of the drying oven 1 are provided with sliding grooves 14. The extension direction of the sliding grooves 14 is consistent with the radial direction of the drying drum 2. The two ends of the follower rod 6 are respectively slidably connected in the two sliding grooves 14.

[0046] The follow-up structure includes a drive disk 4. Two drive disks 4 are provided and fixedly sleeved on both ends of the drive shaft 31. Multiple first guide blocks 41 are fixed on the drive disk 4. The multiple first guide blocks 41 are evenly distributed along the periphery of the drive disk 4. Each first guide block 41 has an arc-shaped guide surface and a side wall extending in the same direction as the radial direction of the drying drum 2.

[0047] The slide 14 is also equipped with a reset component for applying compressive stress to the follower rod 6, which makes the follower rod 6 always tend to move toward the axis of the drying drum 2.

[0048] The reset component includes a compression spring 8, one end of which is fixed to the inner side of the slide groove 14 away from the drying barrel 2, and the other end of which is fixed to the peripheral side of the follower rod 6 away from the drying barrel 2.

[0049] As can be seen from the above structure, combined with the appendix Figures 2-4 When the drive shaft 31 rotates, it drives the drive disc 4 and the drying drum 2 to rotate synchronously. When the drive disc 4 rotates, it drives multiple first guide blocks 41 to rotate synchronously. The arc-shaped guide surface of the first guide block 41 first contacts the follower rod 6 and lifts the follower rod 6, causing the follower rod 6 to slide along the slide groove 14 and compress the compression spring 8. At the same time, it causes the hammer rod 61 to move along the extension direction of the slide groove 14 and leave the striking hole 22. When the follower rod 6 moves to the side wall of the first guide block 41 and separates from the first guide block 41, the hammer rod... Under the elastic force of the compression spring 8, 61 is quickly inserted into the striking elongated hole 22 and hammers the outer wall of the flexible inner liner 5, thereby causing the flexible inner liner 5 to deform inward, ultimately achieving the purpose of cleaning the tea stuck in the main sieve hole 21 and the secondary sieve hole 51; multiple first guide blocks 41 correspond to multiple striking elongated holes 22 respectively, and can work with the compression spring 8 to repeatedly drive the follower rod 6 to move, thereby achieving the purpose of cleaning all the main sieve holes 21 and secondary sieve holes 51 passing through the area of ​​the hammer rod 61, with better cleaning effect.

[0050] Furthermore, the drying barrel 2 is provided with a loading and unloading port 24 extending along the axial direction of the drying barrel 2. A barrel cover 23 is hinged and closed inside the loading and unloading port 24. The other end of the barrel cover 23 is movably engaged with the drying barrel 2 through a limiting member, thereby facilitating the placement and removal of tea leaves.

[0051] The cylinder cover 23 is also provided with a main sieve hole 21 and a striking elongated hole 22;

[0052] There are empty areas on the drying drums 2 on both sides of the inlet 24 where the main screen hole 21 and the long striking hole 22 are not opened;

[0053] A second guide block 42 is fixed at the position of the empty area on the periphery of the drive disc 4. The second guide block 42 covers the empty area and the main screen hole 21 area on the cylinder cover 23 by the stroke of the follower rod 6 being lifted.

[0054] By setting the second guide block 42, when the empty area rotates into the area of ​​the hammer rod 61, the follower rod 6 is always driven away from the drying drum 2 by the second guide block 42, and ensures that the follower rod 6 can move closer to the drum cover 23 again after leaving the empty area, and hammer the flexible inner liner 5 covering the inside of the drum cover 23, so as to clean the main screen hole 21 and the corresponding secondary screen hole 51 on the drum cover 23.

[0055] It should be noted that the flexible inner liner 5 is provided with an openable cylinder at the cylinder cover 23. The cylinder is fixed to the cylinder cover 23 and can open and close with the opening and closing of the cylinder cover 23 to meet the needs of placing and taking out tea leaves.

[0056] Furthermore, a limiting elongated hole 231 is provided on the cylinder cover 23, and the limiting elongated hole 231 extends along the axial direction of the drying cylinder 2;

[0057] The limiting component includes a rotating limiting rod 7, which is a long rod that can move through the limiting elongated hole 231. The lower end of the rotating limiting rod 7 is rotatably connected to the side wall of the drying drum 2 through a shaft column. The diameter of the shaft column is smaller than the width of the limiting elongated hole 231.

[0058] Rotate the limiting rod 7 so that the side wall near the axis of the drying drum 2 is pressed against the outer wall of the drum cover 23;

[0059] When the lid 23 is closed, first rotate the limiting rod 7 so that the position of the limiting rod 7 corresponds to the position of the limiting elongated hole 231, so that the limiting rod 7 can pass through the limiting elongated hole 231. After the lid 23 is closed, simply rotate the limiting rod 7 again so that the position of the limiting rod 7 and the limiting elongated hole 231 is staggered, so that the side wall of the limiting rod 7 abuts against the outer side wall of the lid 23, thereby achieving the purpose of locking the lid 23 and preventing the lid 23 from opening during rotation and causing the tea leaves to scatter.

[0060] The working principle of this utility model is as follows: In daily use, first open the dustproof net 13 and the cylinder cover 23, and put the tea leaves to be dried into the drying barrel 2 (i.e., inside the flexible inner liner cylinder 5) through the feeding port 11 and the loading port 24. Then close the cylinder cover 23 and the dustproof net 13, and open the drying plate and the servo motor 3 so that the drying plate dries the tea leaves. The servo motor 3 drives the drying barrel 2 to rotate through the drive shaft 31 to achieve uniform drying and to remove broken tea leaves and tea dregs.

[0061] During the drying process, the drive disc 4 rotates along with the drive shaft 31. When the drive disc 4 rotates, it drives multiple first guide blocks 41 to rotate synchronously. The arc-shaped guide surface of the first guide block 41 first contacts the follower rod 6, lifting the follower rod 6 so that it slides along the groove 14 and compresses the compression spring 8. Simultaneously, the hammer rod 61 moves along the extension direction of the groove 14 and moves away from the striking hole 22. When the follower rod 6 moves to the side wall of the first guide block 41 and separates from it, the hammer rod 61, under the elastic force of the compression spring 8, quickly inserts into the striking hole 22 and hammers the outer wall of the flexible inner liner 5, causing the flexible inner liner 5 to deform inwards. This also causes the two auxiliary screen holes 5 adjacent to the striking hole 22 to deform inwards. The deformation caused by the deformation is mainly manifested as the inward expansion deformation of the sidewalls. This allows the tea leaves stuck in the main screen hole 21 and the secondary screen hole 51 to move inward under the deformation impact of the flexible inner liner 5 after they are freed from the obstruction. This allows the stuck tea leaves to leave the main screen hole 21 and the secondary screen hole 51, thus cleaning the screen holes during the drying process. This ensures that the efficiency of removing broken tea and tea residue remains stable and improves the screening effect. At the same time, since the flexible inner liner 5 is made of flexible material, the impact between it and the tea leaves when it deforms is also flexible. Therefore, when cleaning the tea leaves that are blocking the screen holes, the integrity of the tea leaves can be largely guaranteed, avoiding the generation of broken tea leaves, ensuring the quality of the dried tea leaves, improving the finished product qualification rate, reducing losses during the drying process, and thus reducing production costs.

[0062] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
